Quantitative Real Time Polymerase Chain Reaction (RT-qPCR)

Quantitative Real Time Polymerase Chain Reaction (RT-qPCR) QUANTITATIVE REAL TIME POLYMERASE CHAIN REACTION (RT-qPCR) Groundworks Every single preliminary succession were structured utilizing the online device Primer 3-BLAST (NCBI) and the preliminaries were gotten from Sigma Aldrich, Bangalore, India. Relative articulation of changing development factor beta (TGF-ÃŽ ²), myosin overwhelming chain beta (ÃŽ ²-MHC), endothelial nitric oxide synthase (eNOS) and glyceraldehydes-3-phosphate dehydrogenase (GAPDH) was examined. Forward and turn around introductions for the above qualities were utilized for enhancement. Table 5. PCR Primer subtleties RNA detachment All crystal were washed with diethyl-pyrocarbonate (DEPC) offered water restrain RNases. Complete RNA was separated utilizing guanidium thiocynate-chloroform-phenol technique for Chomczynski and Sacchi (1987). Absolute RNA confinement pack (BioUltra, Sigma Aldrich,USA) was used for this examination Subsequent to cleaning with saline, heart and aorta tissues were homogenized in denaturing arrangement with newly included ÃŽ ²-mercaptoethanol. After homogenization 2M sodium acetic acid derivation arrangement (pH. 4.0), water immersed phenol and chloroform: isoamyl liquor (49:1) was included. The blend was shaked energetically and permitted to cool on ice for 15 minutes. The blend was centrifuged at 10,000 Ãâ€"g for 20 minutes at 4 oC. The fluid stage was moved in a new cylinder and an equivalent volume of super cold isopropanol was included. RNA was encouraged by putting the example at - 20 oC for 60 minutes. At that point the blend was centrifuged at 10,000 Ãâ€"g for 20 minutes at 4 oC. The pellet was washed with 70% ethanol and RNA was put away in DEPC water at - 80 oC. RNA quality and amount was evaluated by nano-drop spectrometer. Continuous PCR enhancement SYBR Green Quantitative RT-qPCR Kit was utilized in this examination and the PCR try was done in eppendorff realplex mastercycler. 1â µg RNA was opposite interpreted by utilizing Molone murine leukemia infection (M-MuLV) turn around transcriptase according to produces guidelines. At that point the intensification program (94 oC †45 seconds, toughening †45 seconds, augmentation 72 oC-1 moment) was applied with explicit strengthening temperature. The strengthening temperatures of TGF-ÃŽ ², ÃŽ ²-MHC, eNOS and GAPDH were 58, 52, 55, and 55 oC, separately. The particularity of the groundworks was affirmed by settling the PCR items in 1.5% agarose gel electrophoresis. The relative overlay change of articulation was determined by standardized the articulation with GAPDH. The RT-qPCR results were measured utilizing the ‘threshold line’ and the ‘cycle threshold’. The ‘threshold line’ is where the response arrives at a fluorescent force above foundation. The cycles at which the examples arrive at this level is known as the ‘cycle threshold’ (Ct). The factual investigation of the RT-qPCR results was determined by utilizing the à ¢Ã‹â€ Ã¢â‚¬ Ct = (Ct estimation of quality of premium †Ct estimation of GAPDH). Relative quality articulation was acquired by à ¢Ã‹â€ Ã¢â‚¬ à ¢Ã‹â€ Ã¢â‚¬ Ct techniques (à ¢Ã‹â€ Ã¢â‚¬ Ct test †à ¢Ã‹â€ Ã¢â‚¬ Ct of control), with the utilization of the benchmark group as a calibrator for examination of all obscure example quality articulation levels. The relative quality articulation overlay change was gotten from 2â€Ã ¢Ã‹â€ Ã¢â‚¬ à ¢Ã‹â€ Ã¢â‚¬ Ct (Schmittgen and Livak, 2008). IMMUNOHISTOCHEMICAL LOCALIZATION (IHC) Immunohistochemistry (IHC) IHC was proceeded as portrayed by Rocha et al., (2009) utilizing Super Sensitive Polymer-HRP Detection System unit, from Biogenex, USA. The Super Sensitive Polymer-HRP Detection System is an atypical location framework utilizing a non-biotin polymeric innovation that utilizes two significant segments: a Poly-HRP reagent and super Enhancerâ„ ¢. As the framework did not depend on the biotin-avidin framework, the issues related with endogenous biotin are totally disposed of. The location of antigens in tissues by immunostaining is a two-advance procedure. The initial step includes the authoritative of an immune response to the antigen of intrigue and the subsequent advance includes the identification and representation of bound immunizer by one of an assortment of chemical chromogenic frameworks. The decision of identification framework will significantly affect the affectability, utility and convenience of the technique. System Paraffin-installed tissue was sliced to get segments of around 4  µm thickness. The mounted paraffin-installed cuts are deparaffinized in xylene and rehydrated utilizing an ethanol/H2O slope. Warmth intervened antigen recovery step was completed for 10 min and afterward the slides were permitted to cool to room temperature for another 20 min. This was trailed by peroxidase square treatment (to square endogenous peroxidase compound movement) for 10-15 min and afterward power square treatment (to square vague authoritative of antibodies to exceptionally charged locales) for another 15 min. The areas were hatched with the concerned weakened essential counter acting agent answer (for 2 h (1:200)) trailed by treatment with the super enhancer answer (for 30 min) and very touchy Poly-HRP answer (for 30 mins). After shading improvement with DAB and counterstaining with haematoxylin, the segments were seen under the magnifying lens and photos were taken. TRANSMISSION ELECTRON MICROSCOPIC STUDY The ultrastructure of the heart example was analyzed by Transmission Electron Microscopy (TEM) as per the strategy for Lang (1987), by the method of slight segmenting. Reagents Glutaraldehyde arrangement: 3% Osmium tetroxide: 2% osmium tetroxide in 10 mM sodium phosphate cradle, pH - 7.4 Ethanol: 75%, 95% and 100% Uranyl acetic acid derivation: 1% Lead citrate: 3% Sodium phosphate cradle: 0.1 M, pH 7.4 Strategy Following the penance, the heart tissues were dismembered and fixed with an answer of 3% glutaraldehyde for 2 hours at room temperature and washed threefold with phosphate support to expel glutaraldehyde. Post-obsession was finished by an answer containing 2% osmium tetroxide in 10mM sodium phosphate cradle and left for the time being. At that point, the osmium tetroxide arrangement was expelled and supplanted with 75% ethanol. This decreases the rest of the osmium tetroxide to osmium dioxide, which frames an accelerate in the liquor. Following 10 minutes, the liquor was supplanted with a couple of ml of 75% ethanol. Following 30 minutes, the liquor was supplanted with 95% ethanol and left for 30 minutes. This arrangement was supplanted with 100% ethanol and washed threefold and afterward dried in CH3)2CO. After drying out, the tissues were equilibrated for 30 minutes in 1:1 blend of epoxy propane and the inserting medium, epon 812 (additionally called epikote gum 812). A blend of the sap and two solidifying operators, dodecyl succinic anhydride and methyl anhydride were utilized. A diamine impetus for the most part N-benzyl-N-diethylamine was included not long before use. The 1:1 blend was poured off and supplanted with full quality sap. This progression was rehashed a few times to guarantee full invasion of the implanting medium. The tissue was then moved to a bar case with a wooden stick and the container was loaded up with new pitch blend. The wooden stick was utilized to prod the example down to the focal point of the base of the case. Next, the square holder was set with the example in tourist oven at 60 °C for 48 hours to polymerize the gum totally. When the squares are solidified, they are prepared for segmenting. The finishes of the example squares were cut utilizing glass b lades and ultra slender areas were cut utilizing a LKBUM4 ultramicrotome. The segments were picked upon carbon frameworks and post-recolored with joined uranyl and lead stain and flushed with refined water and dried. In the wake of drying, the frameworks were inspected under a Philips EM201C transmission electron magnifying lens (Philips, Eindhoven, Netherlands). WESTERN BLOT ANALYSIS Western smearing was performed to examine the articulation example of eNOS in the aorta and reperfused hearts as per technique for Laemmli (1970). Standard Following the protein estimation, the examples were isolated utilizing SDS-PAGE gel electrophoresis and the isolated atoms are blotched onto a polyvinylidene fluoride (PVDF) layer. In the wake of hindering, the essential counter acting agent was added and permitted to tie to the protein followed by washing (which evacuates vaguely bound immunizer); at that point a compound named auxiliary neutralizer was included, to recognize the essential counter acting agent. The area of the auxiliary immune response was controlled by including a proper substrate for the compound conjugated to the optional counter acting agent. Reagents Acrylamide stock: 30% acrylamide, 0.8% N,N†²-methylene bisacrylamide Isolating gel cushion: 1.5 M Tris, pH 8.8 Test cushion: 0.5 M Tris, pH 6.8 Sodium dodecylsulfate (SDS): 10% Ammonium per sulfate (APS): (10%) N,N,N,N-tetramethylethylenediamine (TEMED) Isolating gel overlaying arrangement: Water-soaked isobutanol Test Buffer: Tris (0.5M, pH 6.8)- 2.5 mL SDS (10%)- 4.0 mL Glycerol (100%)- 2.0 mL ÃŽ ²-Mercaptoethanol-0.8 mL (or 1 M DDT-0.5 mL) Bromophenol Blue (0.1%)- 300  µL Refined water (400  µl) to 10.0 mL Running gel cradle Tris-6.05 g Glycine: 28.80 g 10% SDS: 10.0 mL or (1.0 g) Refined water to 1000 mL Recoloring arrangement Coomassie splendid blue R250-300 g Methanol-80 mL Acidic corrosive 20 mL Refined water-100 mL Destainning arrangement Acidic corrosive 100 mL Methanol-300 mL Refined water: 1000 mL System The aortic tissues were homogenized in a super cold radio immuno precipitation cradle (RIPA) (1% Triton, 0.1% SDS, 0.5% deoxycholate, 1 mM/L EDTA, 20 mM/L Tris (pH 7.4), 150 mM/L NaCl, 10 mM/L NaF, and 0.1 mM/L phenylmethylsulfonyl fluoride (PMSF)).

How to Fix a Dried out Sharpie

The most effective method to Fix a Dried out Sharpie A Sharpie is an incredible indelible marker, yet its inclined to drying out in the event that you use it a great deal or dont seal the top flawlessly. You cannot wet the pen with water to get the ink streaming (a tip that works for water-based markers) since Sharpies depend on natural solvents to break down the ink and make it stream. Thus, before you toss out dead, dried-out Sharpies or other indelible markers, attempt this tip: Sharpie Rescue Materials 91% Rubbing AlcoholDried Out Sharpie Pen Indelible markers contain natural solvents, which are famously awful about vanishing ceaselessly before you get an opportunity to utilize the entirety of the ink. To save a dried pen, you have to supplant the dissolvable. The most effortless choice is to utilize scouring liquor. On the off chance that you can discover 91% or 99% scouring liquor (either ethanol or isopropyl liquor), those will be your most logical option for fixing your marker. In the event that you approach different synthetic concoctions, you could likewise utilize another high-proof liquor, xylene, or conceivably CH3)2CO. You likely wont have extraordinary accomplishment with scouring liquor that contains a great deal of water (75% or lower liquor). 2 Easy Ways To Save a Sharpie There are two speedy and simple approaches to fix a dried Sharpie. The first is for crisis use, when you dont need a great deal of ink or for the pen to keep going forever. Essentially empty a touch of liquor into a little holder or the pen top and absorb the tip of the Sharpie the fluid. Leave the pen in the liquor for at any rate 30 seconds. This should disintegrate enough ink to make it stream once more. Wipe any abundance fluid off the nib of the pen before utilizing it or, in all likelihood the ink could be runny or paler than expected. A superior strategy, which makes the Sharpie all around great, is to: Handle the pen in your grasp and either pull it open or use pincers to isolate the two pieces of the pen. Youll have a long segment that contains the pen and cushion that holds the ink and the back bit that essentially shields the Sharpie from drying out when its topped or spilling ink on your hands when you write.Hold the recording some portion of the pen, as though you would compose with it. Youre going to utilize gravity to take care of the new dissolvable into the Sharpie.Drip 91% liquor (or one of different solvents) onto the ink cushion (same piece, however inverse side of the composing some portion of the pen). Keep including fluid until the cushion appears saturated.Put the two bits of the Sharpie back together again and top the Sharpie. On the off chance that you like, you can shake the pen, yet it doesnt truly have any kind of effect. Permit a few minutes for the dissolvable to totally immerse the pen. The dissolvable needs a touch of time to work its way into the nib of th e pen, yet you dont need to wet the composing part to get the ink streaming. Uncap the Sharpie and use it. It will be all around great! Simply make sure to recap the pen firmly before putting away it for sometime later or youll be starting over from the beginning once more.

Everyday Minimalists

Everyday Minimalists People often ask us whether there are any normal minimalists out there. Meaning: are there any minimalists who make a living in more conventional ways than, say, writing? Are there minimalist teachers, bankers, factory workers, engineers, architects, lawyers, security guards, plumbers, grocery-store clerks? The short answer is: yes, thousands. While on tour, weve met thousands of minimalists who lead comparatively conventional livesâ€"from CEOs, salesmen, and professors, to philanthropists, social workers, and rabbis. But why dont we ever hear about their stories? While this may seem like an irksome paradox at first, its really just plain old commonsense: the few minimalists who share their journeys are, by definition, more well-known than the ones who dont. Take, for example, our friends Jamar, a teacher in Cincinnati; Adam, a pastor in Tennessee; and  Jessica and Matt, an awesome couple in Los Angeles. Although they are minimalists, rarely do these individuals gasconade publicly over their simpler lives. Rather, they use minimalism privately as a tool to focus less on consumption and more on health and relationships, experiences and creativity. Thus, it is difficult to point  to these people as examples of everyday minimalists, because simple living is part of their interior  lives. They are private citizens, and so for obvious reasons, rarely do we see public illustrations of their journeys. (By the way, this is why we interviewed dozens of them for our documentary, to shed light on the silent majority.) At the end of the day, there are many different flavors of minimalism. The minimalists who publicly share their journeyâ€"people such as  Courtney and Patrick and Allen et al.â€"present  their recipe in  hopes that others may glean insight and tweeze out a few ingredients to create their own flavor of minimalism, using their own recipe. These sharersâ€"bloggers and authors and speakersâ€"are just the tip of the iceberg, though. For every one minimalist who shares her journey with the masses, there are thousands who live their private lives with more meaning but less stuff.

Long Term Effects Of Childhood Maltreatment - 1885 Words

Long Term Effects of Childhood Maltreatment It has been known, for many years, that childhood maltreatment, including physical abuse, emotional abuse, neglect, interparental violence, and sexual abuse, has an adverse effect on a developing child. These effects have been thought to be linked to adults later having cognitive deficits and mental disorders when compared to adults with no history of childhood maltreatment (Tomoda, Polcari, Anderson, Teicher, 2012). It has also been shown that adults who experience childhood maltreatment are more prone to many medical illnesses than their healthy counterparts (Keeshin, Cronholm, Strawn, 2012). With more recent advances in technology, scientists have been able to research exactly how childhood maltreatment affects development through methods such as MRI, fMRI, and genetic tests (Teicher, Anderson, Polcari, 2012). Using these findings, scientists have begun to show how childhood maltreatment affects adults later in life. The following literature will support the claim that childhoo d maltreatment leads to abnormal neurological development which can later have adverse effects on the adult’s mental and physical health. Childhood emotional abuse has been found to have an effect on the serotonin transporter gene, 5-HTTLPR. This gene exists in both adults with a history of abuse and adults without.

Musical Performance Free Essays

The history of music predates the written word and is tied to the development of each unique human culture. Music has been used as meditational music since the very dawn of civilization, because it balances the human organism through its rhythmic pattern of tones, which are generated in a harmonic relationship with each other. Mantras originated in the Vedic religion of India, later becoming an essential part of the Hindu tradition and a customary practice within Buddhism, Sikhism and Jainism. We will write a custom essay sample on Musical Performance or any similar topic only for you Order Now Indian music and mantras bring us back in to the physical world every day.   Most of the indian songs were written by   saints for devotion and meditation. This music was created in order to give people better feelings. Not long ago I visited the concert of a not very famous group â€Å"Atmosphere†. It consisted of two women who chanted mantras and three men who played some instruments. Those instruments included pakhawaj , violin, flute. The most exotic of those instruments were pakhawaj and flute. Pakhawaj   is a long bodied wooden drum with both ends covered in skin. Played horizontally with the fingers and palms of both hands, the right hand surface is tuned to the pitch required and the left hand surface provides the base. Flute, carved from bamboo, is made in every possible size. It is usually played in a vertical position. The combination of the sounds made by those instruments was excellent. The music they played was composed by the members of those group. They took the text of a famous Indian mantras and   composed   a modern joyful music for chanting it. Actually, when they were singing and playing they were meditating themselves. Moreover, a lot of people sitting in the hall were meditating too. While singing the women were dancing. There were no special costumes, except an embroidered Indian shirts. Of course they were influenced by some chanters of mantras, but intheir group they expressed their individualities. To tell the truth, I liked the style of their performance greatly. I think it was a good idea to combine mantras with a modern music. References â€Å"Atmosphere: Music Group†. (2006).

Green Marketing Its Influence on Consumer Behavior

Question: Discuss about theGreen Marketing for Its Influence on Consumer Behavior. Answer: Introduction: The term green marketing is used in the context of marketing of such materials, which are green in nature. The products, which are GREEN, are produced, packaged, labeled and transported considering the environment. Quite naturally, such products are costlier than products, which are not manufactured, in a green process. Green products are measured on the basis of the benefits they provide to the environment. The assumption being made is that the consumer will be able to view the product as environment friendly and thus would buy the product / goods (Sharma and Trivedi 2016). The present research will focus on the marketing principles and its impact of the consumers buying behavior. Literature Review Green marketing as a concept had two objectives. The primary objective was to deliver environment friendly goods to the consumer. These products cause minimal damage to the environment since the products are free of pesticides. To achieve this objective such products are produced taking into consideration the effects on the environment. A green consumer for this purpose is defined as the one who purchases green products. Such consumers believe that by the purchase of such products they are helping the environment. According to the EU 10% of the consumers in Europe recognize the benefit of green products. They understand the importance that such products have on the ecology and energy (Boztepe 2016). Green marketing is a very hot topic with the consumers identifying the importance of such products. The consumers of green products are aware of the different products in the market and the methods of manufacture of such materials. These consumers are environment friendly and they are concerned for the environment. Thus, marketing organizations are employing different strategies to market such products and to retain loyal consumers. Retaining of the consumers is important in the long run because of the high cost of green products (Saini 2013). The strategy of green marketing is based on the 4 Ps which are Product, Price, Place and Promotion. The above 4 Ps are solved with Customer Solutions, Customer Cost, Communications and Convenience (Deshwal 2012). A study was conducted in Australia to analyze the relationship between green marketing and the intentions of the consumer in purchasing green products. The consumers who were graduate students were shown three different types of advertisement and asked their intention to purchase the product. The results revealed that the consumers did not differ in purchase intentions across the advertisement. However, the same study also revealed that the consumers behavior was directly related to environmental impact. Hence the study showed that green marketing intentions should be aligned towards the environmental impact of the green products (Grimmer and Woolley 2014. The concern of the consumer towards an environment friendly world is growing. This concern is due to the green marketing strategies being taken up by the marketer. The awareness of the consumer towards a green product has been influenced by: his reduction in the use of non-green products, his eagerness to purchase green products and use of environment friendly ways of living. From the study done by Suki (2013) in Malaysia that the purchasing decision of green products by the consumers was directly related to the awareness, the price of the product. The awareness of the brand of the product is also an important factor in his decision to purchase. Although the concept of green marketing started in the 60s it was not until the 90s that such products were visible. The concept of green marketing starts from the planning of functions to generate such product which are green. The green purchasing behavior of human beings shows his intention to contribute to the environment (Akehurst Afonso and Gonalves 2012). Research Aim The aim of the research is to evaluate the green marketing strategies and how it influences the purchasing behavior of the consumer Research Question The research question for this assignment is as follows: Do you prefer green products over normal products? How often do you purchase Green Products. ? Are you aware of the harmful effects of pesticides on consumable food products ? Research Objective The objective of the research is as follows: To explore the ways in which green products are marketed To examine if the consumer is price conscious or quality conscious To gain an insight into the awareness amongst the consumers towards green products Research Methodology Primary data will be collected in the form of a survey questionnaire (refer Appendix for survey questionnaire). The primary data collection method is chosen since data from a large population can be collected and then further analyzed. The focus of the survey would be to understand the awareness of the consumers towards green products. The survey would also be able to understand the concern of the consumers towards the environment. It would focus of the long term purchase behavior of the consumers. Exploratory data analysis techniques with multiple regression analysis would be used for the analysis (Delafrooz, Taleghani and Nouri 2014). The analysis will be used to understand the strategies that the marketer of the green product uses to successfully market a green product. Expected Research Outcome The study will demonstrate the techniques that a producer of green product uses to market his goods. Green products are mostly cost-intensive. Thus, they must be effectively marketed so that consumers prefer a green product to a non-green product. The study will also demonstrate if the consumer has enough information about the beneficial effects of Green products to the environment. The study will therefore be able to say that the perceived importance of a green product has percolated to the consumer. The study wishes to understand that given a choice between green and non-green products will the consumer choose a green product. Conclusion The concept that the environment is our concern has given rise to consumer products which are green. These products are manufactured keeping the environment in mind. Thus to manufacture such products a cost is involved. Thus a marketer of green products should use different marketing strategies to influence a consumer to purchase a eco-friendly product. They should be able to show the perceived the beneficial effects of such products. They should emphasize the importance of such products on the environment to offset the higher price. These green products should be advertised aggressively so that the consumers interest on such products increases. Then only will the marketer be able to create new, loyal green consumers.

Municipal Waste Music Reveiw Essay examples

Municipal Waste Music Reveiw Essay examples Municipal Waste Music Reveiw Essay examples I went to see Municipal Waste on January 29th of this year. It was an impromptu event held at someone's house on the 600 block of west Marshall St and I was fortunate enough to experience "The Waste" raw in the someone's moldy basement. Municipal Waste is a thrash-metal band that formed right here in Richmond, VA back in 2000. There are four members, Tony with vocals and front man, Phil, Ryan and Dave. Although there are only three instruments, bass, guitar and drums, along with vocals, the dynamic of Municipal waste is loud and high-pitched. It resonates. The songs are short but really intense. Within the first two songs, I noticed a lot of lyrical references to alcoholism, "thrashing", partying and life in Richmond. There were also some mention of mutants which is depicted on a lot of the Municipal Waste memorabilia that I saw amongst the fans/crowd that night. The Waste seemed to have a lot of influences from bands like, Suicidal Tendencies, DRI, and Corrosion of Conformity. T he Waste was very well received, to no surprise, because they are a locally formed band that has soared in popularity over the last thirteen years and has become an international success, especially among Europeans into the metal sub-culture. And although they have a healthy, world-wide fan base, they have no pretentious demeanors and are intertwined with the social and music scene in their hometown. In fact, most people there at the show were acquaintances or friends of the band. They are

Energy Independence Psychology Personal Statement

Energy Independence Psychology - Personal Statement Example President Obama’s rhetoric about the green economy and independence from foreign energy producers is just that—rhetoric. Sadly, the President has played politics with this issue, refusing to pursue energy programs at home that would open up domestic sources of oil and gas. This is unfortunate especially because it means America is investing in a phantom â€Å"green† sector of the economy that is nowhere near to be being ready to take on the major demands of those who require energy The truth is that America has more than enough natural gas and oil within its own domestic territory to fuel this country for a long time to come. Those who refuse to recognize this are living with their heads in the sand. They need to wake up and begin to see that we have everything we need within our own country. I for one would like to see more drilling done in Alaska and in the Gulf of Mexico. America must start providing its own energy rather than relying on Arab dictators. Green energy projects across the U.S. are going bust (Paugh). There are a number of psychological reasons why people might endorse Obama’s green economy ideas. There is sometimes an information bias when it comes to politics. People often get caught up in their own world. They only read newspapers which they agree with and will only watch TV shows where the speakers tell them what they want to hear.

Application of Enginerring Principles Coursework

Application of Enginerring Principles - Coursework Example Due to centrifugal force, clean mud overflows, and the waste particles (together with some amount of fluid) enters the mesh through the bottom outlet of the hydrocyclone. The vibrating mesh further sieves the unwanted particles out, leaving only the pure mud suspension to pass through it. Hence pure mud suspension is obtained. The efficiency of the mud cleaner and the range of sizes of the waste particles that may be sieved out, depends on many factors like cone angle, diameter of the inlet, diameter of overflow pipe, diameter of the bottom outlet of hydrocyclone, the fineness of the mesh, vibration characteristics of the mesh, viscosity and density of the fluid, density and size of the waste particles etc. b) The three components where angular motion is involved are: hydrocyclone, pump, drill pipe. Hydrocyclone Here, the centrifugal force that is a characteristic of a system having angular motion is utilized to separate coarser and finer suspended particles. In hydrocyclones, viscou s forces are also produced by the angular motion. Because of the difference in densities of the suspended waste particles and the fluid, there will be difference in the centrifugal forces each of these subjected to. This difference in the centrifugal force is responsible for the separation of coarser waste particles and finer (required) particles that are suspended in the fluid. ... ncing has to be done properly, bearings have to be selected properly, lubrication should be taken care of, centrifugal forces (and centrifugal stresses) should be considered while designing the components, blade reactions have to be considered for pumps. Drill pipe Many a times drill pipes rotate and the rotation is greatly responsible for the cutting. But sometimes, even when the rotation of the drill pipe is not the main force behind drilling, a slight rotation of the drilling pipe is necessary for a successful drilling. As with any rotating components (which have angular motion), balancing has to be considered while designing drilling pipes. In addition, buckling should also be taken note of. c) Velocity distribution in a drill pipe during the first stage is given by (cm/s) (1) Differentiating (1); The acceleration, (2) (i) When acceleration is minimum, Hence, from (2), (3) Solving (3), When acceleration is minimum, Hence, Hence, (ii) Assuming that the acceleration is proportional to the velocity during the whole period; Final velocity in a further 35 second = Final velocity after (20 + 35) second = Final velocity after 55 second = (12%/20)*55 = 33% increase in the velocity (iii) To get the displacement profile for the first stage, integrating (1); Displacement (4) where c is a constant The displacement profile is a fourth order polynomial during the first stage. The displacement profile may be obtained by plotting (4) using MATLAB. The profile looks similar to Figure 2. Figure 2. Displacement Profile for the First Stage To get the velocity profile for the second stage, acceleration proportional to velocity during the whole period of the second stage implies that the velocity variation during this stage is exponential. The profile looks similar to Figure 3. Figure

Classical Conditioning Theories And Its Uses In An Educational Setting

Classical Conditioning Theories And Its Uses In An Educational Setting In this paper, we will describe classical and operant conditioning theories and its uses in an educational or work setting. It will begin with differences between classical and operant conditioning, followed by specific examples and applications for each developmental level (infancy, early childhood, middle childhood, adolescence, or early childhood). A discussion on the use of rewards from a philosophical and practical viewpoint will follow with different developmental and learning theories that can be applied in an educational or work setting. Finally, a brief summary of definitions and terms of the theory, discussing specific examples, benefits, and challenges while implementing this theory. Classical and Operant Conditioning According to Pavlov, learning begins with a stimulus-response which is classical conditioning (p.47). Learning should reflect a change in behavior. The stimulus and response noted within the working setting may not see a change in behavior. The classical conditionings in the work setting include: A customer service representative in a call center receives call quality scores via e-mail. The customer representative experiences anxiety each time the score(s) are given. The departmental potlucks create an atmosphere of food and fun. The departmental service level suffers because the customer service representatives are not adhering to scheduled breaks and lunches. The emergency room receives the charts daily. As the end of the calendar month approaches overtime is required to complete all work received. In operant conditioning, learning occurs because of rewards and punishment. Rice indicated, Satisfying consequences bring about changes in behavior (2001). Operant conditioning is often used in the educational or work setting. His or Her father gives them a credit card at the end of their first year in college because they did so well. As a result, their grades continue to get better in their second year. A professor has a policy of exempting students from the final exam if they maintain perfect attendance during the quarter. The professors policy showed a dramatic increase in his students attendance. Customer service representatives strive daily to meet the quarterly incentive. The adherences to break and lunch schedules are enforced. Examples of operant and classical conditioning are prevalent in the everyday lives of many and are seen in the educational environment. An example of operant conditioning during the infancy stage occurs when a caregiver is effective in comforting a crying infant, the infant stops crying. The removal of the unpleasant crying reinforces the caregivers comforting technique. The caregiver is apt to apply the same method of comforting the next time he cries. As an example of classical conditioning during the infancy stage occurs when a baby bottle is inserted in the infants mouth. This brings out a reflexive unlearned response of sucking. The infant can develop a conditioned to the baby bottle; the sucking occurs as soon as the infant sees a baby bottle. The following will provide examples of operant conditioning and classical conditioning during the early childhood stage in an educational environment. As an example of operant conditioning during the early childhood stage, when a student raises his or her hand and waits to be called on to receive something good as a reward. The rewards come in many forms for example a reward is the student receiving a praise or a piece of candy for his or her good behavior. Another example of classical conditioning during the early childhood stage is, when a student calls a classmate an inappropriate name. The teacher may call the student with the inappropriate behavior aside and reprimand him or her. The teacher would have that student take a time out or write sentences as of why he or she should not perform the action of calling the other student inappropriate names (Tuckman, 2010). The following will provide examples of operant conditioning and classical conditioning during the middle childhood stage in an educational environment. As an example of classical conditioning during the middle childhood stage, when a student who seldom associates with other students is encouraged to associate with others, is given praise by the teacher. As an example of classical conditioning during the middle childhood stage, a student has a fear of test taking. In the past, the student has always performed poorly when taking a test. The teacher is aware the student knows the material. The teacher could work with the student by giving him or her series of tests the student could pass. The teacher would provide positive feedback to the student to reinforce the good grade. The student would associate the test taking with positive feedback, and then the student would no longer have a fear of taking test. The following will provide examples of operant conditioning and classical conditioning during the adolescence stage in an educational environment. As an example of operant conditioning during the adolescence stage, when an above average child is receiving an average grade a parent could use monetary rewards if he or she receives As in school however, if the child receives an undesirable grade, the child would pay the parent as a means of punishment. During the adolescence stage, students enjoy working in groups on assignments and projects. As an example of classical conditioning during the adolescence stage, the teacher advises the students to work with the partner of choice if the class exhibits appropriate behaviors until that point in the lesson. If the class is not well behaved, the class does not get to work in groups. If the class exceeds the teachers expectations of appropriate behavior, the class is allowed to work in groups. The students behavior gives a definite response, w hich is a consistent reaction to the classes actions. Rewards Over the years punishment and rewards have been used to control behavior. The concern is that money, high grades, and even praises may be effective in a persons performance, but performance and interest can only remain constant as long as the reward is continuous. Rewards and punishments are ways of manipulating behavior. These two methods are used in our educational environment. These methods are saying to the child, if he or she does this, we will give him or her this, and if he or she does that, we will take away this. The question that arises is as teachers are we using these methods appropriately and is our children benefiting from the methods as a hold. What is the purpose of punishment? The purpose of punishment is to decrease certain responses. There are two types of punishments. Punishment I represents an appearance of an unpleasant stimulus, and punishment II removes the unpleasant stimulus. Punishment can be effective by immediate reasoning, or infrequent reasoning. The purpose of a reward is to let the student know that he or she has done an impressive job. The reward is used to increase the students ability to perform better or do more because his or her performance is already at or above level. This reward can cause a students desire to fail in his or her ability, and become disinterested because he or she has already reached his or her level of attainment. The purpose of reinforces is to increase desired responses and behaviors. We use these reinforces to receive a positive or negative response. The focal point is not principally on rewards and punishment. It is to create an atmosphere that increases motivation. Learning Theory There is no one perfect option in developing a strategy or theory of what would best to used in a classroom or workplace setting. The human mind has been studied for thousands of years, and there is not one study that can be reproduced exactly when it comes to human thinking. The classroom is set up based on the teachers experiences as well as educational knowledge. Starting with the learning focus model, the classroom is set up in the following way to enhance the learning environment. 1) Self- Regulated students are students who develop goals, monitor goals, practice met cognition, and use effective strategies. 2) Teacher Characteristics is expressed in personal teaching efficacy, modeling and enthusiasm, caring as well as a positive expectation of the students abilities. Promoting students motivation in the classroom involves instructional variables, instructional focus, personalization, involvement, and feedback. In comparing Piaget with Vygotsky, Piaget saw interaction primarily as a mechanism for promoting assimilation and accommodation in individuals. Whereas, Vygotsky developed his ideas based on learning and development, which arises directly from social interactions, which means individuals cognitive developments are a direct result of interactions with other people. The role of language is central to Vygotskys theory, and it plays three different roles in development (Eggen Kauchak, 2007, p.46). The first role is giving learners access to knowledge. Second, language providing the learners with cognitive tools that allows humans to think about their surroundings and resolve problems. The third role that language plays is helping the learner with regulation and reflection of his or her own thinking. According to Vygotsky, learning occurs when people acquire specific understanding, Thomas, 32(3), 656). In reviewing the research of the three different theories of motivationbehavioral theo ries humanistic theories and cognitive theoriesthe researcher has to study the development of the humanistic views of Charles Maslows hierarchy of needs. Looking at Maslows two-step processes, the first step is Deficiency needs, which includes survival, safety, belonging, and self-esteem. The second step, Growth needs, includes intellectual achievements, anesthetic appreciation, and self-actualization (Eggen Kauchak, 2007, p.303). This researcher believes that if the work environment or the classroom environment could combine Piaget, Vygotsky and Maslows theories in to one basic idea, one would have the closest thing to a perfect understanding of human physical and cognitive development.

Investigating Ratios of Areas and Volumes

Investigating Ratios of Areas and Volumes In this portfolio, I will be investigating the ratios of the areas and volumes formed from a curve in the form y = xn between two arbitrary parameters x = a and x = b, such that a < b. This will be done by using integration to find the area under the curve or volume of revolution about an axis. The two areas that will be compared will be labeled ‘A’ and ‘B’ (see figure A). In order to prove or disprove my conjectures, several different values for n will be used, including irrational, real numbers (? , v2). In addition, the values for a and b will be altered to different values to prove or disprove my conjectures. In order to aid in the calculation, a TI-84 Plus calculator will be used, and Microsoft Excel and WolframAlpha (http://www. wolframalpha. com/) will be used to create and display graphs. Figure A 1. In the first problem, region B is the area under the curve y = x2 and is bounded by x = 0, x = 1, and the x-axis. Region A is the region bounded by the curve, y = 0, y = 1, and the y-axis. In order to find the ratio of the two areas, I first had to calculate the areas of both regions, which is seen below. For region A, I integrated in relation to y, while for region B, I integrated in relation to x. Therefore, the two formulas that I used were y = x2 and x = vy, or x = y1/2. The ratio of region A to region B was 2:1. Next, I calculated the ratio for other functions of the type y = xn where n ? ?+ between x = 0 and x = 1. The first value of n that I tested was 3. Because the formula is y = x3, the inverse of that is x = y1/3. In this case, the value for n was 3, and the ratio was 3:1 or 3. I then used 4 for the value of n. In this case, the formula was y = x4 and its inverse was x = y1/4. For the value n = 4, the ratio was 4:1, or 4. After I analyzed these 3 values of n and their corresponding ratios of areas, I came up with my first conjecture: Conjecture 1: For all positive integers n, in the form y = xn, where the graph is between x = 0 and x = 1, the ratio of region A to region B is equal to n. In order to test this conjecture further, I used other numbers that were not necessarily integers as n and placed them in the function y = xn. In this case, I used n = ?. The two equations were y = x1/2 and x = y2. For n = ? , the ratio was 1:2, or ?. I also used ? as a value of n. In this case, the two functions were y = x? and x = y1/?. Again, the value of n was ? , and the ratio was ? :1, or ?. As a result, I concluded that Conjecture 1 was true for all positive real numbers n, in the form y = xn, between x = 0 and x = 1. 2. After proving that Conjecture 1 was true, I used other parameters to check if my conjecture was only true for x = 0 to x = 1, or if it could be applied to all possible parameters. First, I tested the formula y = xn for all positive real numbers n from x = 0 to x = 2. My first value for n was 2. The two formulas used were y = x2 and x = y1/2. In this case, the parameters were from x = 0 to x = 2, but the y parameters were from y = 0 to y = 4, because 02 = 0 and 22 = 4. In this case, n was 2, and the ratio was 2:1, or 2. I also tested a different value for n, 3, with the same x-parameters. The two formulas were y = x3 and x = y1/3. The y-parameters were y = 0 to y = 8. Again, the n value, 3, was the same as the ratio, 3:1. In order to test the conjecture further, I decided to use different values for the x-parameters, from x = 1 to x = 2. Using the general formula y = xn, I used 2 for the n value. Again, the ratio was equal to the n value. After testing the conjecture multiple times with different parameters, I decided to update my conjecture to reflect my findings. The n value did not necessarily have to be an integer; using fractions such as ? and irrational numbers such as ? did not affect the outcome. Regardless of the value for n, as long as it was positive, the ratio was always equal to n. In addition, the parameters did not have an effect on the ratio; it remained equal to the value used for n. Conjecture 2: For all positive real numbers n, in the form y = xn, where the graph is between x = a and x = b and a < b, the ratio of region A to region B is equal to n. . In order to prove my second conjecture true, I used values from the general case in order to prove than any values a and b will work. So, instead of specific values, I made the x-parameters from x = a to x = b. By doing this, region A will be the region bounded by y = xn, y = an, y = bn, and the y-axis. Region B is the region enclosed by y = xn, x = a, x = b, and the x-axis. The formulas used were y = xn and x = y1/n. The ratio of region A to region B is n:1, or n. This proves my conjecture correct, because the value for n was equivalent to the ratio of the two regions. . The next part of the portfolio was to determine the ratio of the volumes of revolution of regions A and B when rotated around the x-axis and the y-axis. First, I determined the ratio of the volumes of revolutions when the function is rotated about the x-axis. For the first example, I will integrate from x = 0 to x = 1 with the formula y = x2. In this case, n = 2. When region B is rotated about the x-axis, it can be easily solved with the volume of rotation formula. When region A is rotated about the x-axis, the resulting volume will be bounded by y = 4 and y = x2. The value for n is 2, while the ratio is 4:1. In this case, I was able to figure out the volume of A by subtracting the volume of B from the cylinder formed when the entire section (A and B) is rotated about the x-axis. For the next example, I integrated the function y = x2 from x = 1 to x = 2. In this case, I would have to calculate region A using a different method. By finding the volume of A rotated around the x-axis, I would also find the volume of the portion shown in figure B labeled Q. This is because region A is bounded by y = 4, y = x2, and y = 1. Therefore, I would have to then subtract the volume of region Q rotated around the x-axis in order to get the volume of only region A. In this case, the value for n was 2, and the ratio was 4:1. After this, I decided to try one more example, this time with y = x3 but using the same parameters as the previous problem. So, the value for n is 3 and the parameters are from x = 1 to x = 2. In this case, n was equal to 3, and the ratio was 6:1. In the next example that I did, I chose a non-integer number for n, to determine whether the current pattern of the ratio being two times the value of n was valid. For this one, I chose n = ? with the parameters being from x = 0 to x = 1. In this case, n = ? and the ratio was 2? :1, or 2?. After this, I decided to make a conjecture based on the 4 examples that I had completed. Because I had used multiple variations for the parameters, I have established that they do not play a role in the ratio; only the value for n seems to have an effect. Conjecture 3: For all positive real numbers n, in the form y = xn, where the function is limited from x = a to x = b and a < b, the ratio of region A to region B is equal to two times the value of n. In order to prove this conjecture, I used values from the general case in order to prove than any values a and b will work. So, instead of specific values, I made the x-parameters from x = a to x = b. By doing this, region A will be the region bounded by y = xn, y = an, y = bn, and the y-axis. Region B is the region enclosed by y = xn, x = a, x = b, and the x-axis. In this example, n = n and the ratio was equal to 2n:1. This proves my conjecture that the ratio is two times the value for n. When the two regions are rotated about the x-axis, the ratio is two times the value for n. However, this does not apply to when they are rotated about the y-axis. In order to test that, I did 3 examples, one being the general equation. The first one I did was for y = x2 from x = 1 to x =2. When finding the volume of revolution in terms of the y-axis, it is important to note that the function must be changed into terms of x. Therefore, the function that I will use is x = y1/2. In addition, the y-parameters are from y = 1 to y = 4, because the x values are from 1 to 2. In this example, n = 2 and the ratio was 1:1. The next example that I did was a simpler one, but the value for n was not an integer. Instead, I chose ? , and the x-parameters were from x = 0 to x = 1. The formula used was x = y1/?. In this example, the ratio was ? :2, or ? /2. After doing this example, and using prior knowledge of the regions revolved around the x-axis, I was able to come up with a conjecture for the ratio of regions A and B revolving around the y-axis. Conjecture 4: For all positive real numbers n, in the form y = xn, where the function is limited from x = a to x = b and a < b, the ratio of region A to region B is equal to one half the value of n. In order to prove this conjecture, I used values from the general case in order to prove than any values a and b will work. This is similar to what I did to prove Conjecture 3. So, instead of specific values, I made the x-parameters from x = a to x = b. By doing this, region A will be the region bounded by y = xn, y = an, y = bn, and the y-axis. Region B is the region enclosed by y = xn, x = a, x = b, and the x-axis. The ratio that I got at the end was n:2, which is n/2. Because the value of n is n, this proves that my conjecture is correct. In conclusion, the ratio of the areas formed by region A and region B is equal to the value of n. n can be any positive real number, when it is in the form y = xn. The parameters for this function are x = a and x = b, where a < b. In terms of volumes of revolution, when both regions are revolved around the x-axis, the ratio is two times the value of n, or 2n. However, when both regions A and B are revolved around the y-axis, the ratio is one half the value of n, or n/2. In both situations, n includes the set of all positive real numbers.

Fast Food Essay

Junk food is being blamed for causing many undesirable problems to children. It is referred to any food that is low nutritional value such as instant noodles, potato chips and chocolate bars. Takeaway foods, pre-packaging meals and sugary snack food are also included as junk food (Trab 2005). In response to the problem, I strongly believe that the sale of junk food should be banned. The first reason why junk food should be banned is because it causes behavioral problems in children (Caputo 2005). Most of them contain chemical additives to enhance flavor and colour and to increase shelf life. Furthermore, junk food has a lot of flavor as it is typically high in fat, salt, or sugar and commonly containing synthetic flavor enhancer (Smith 2005). These additives have been shown to cause the behavioral problems such as hyperactivity and pour concentration. Based on a research, it is proven that junk foods are often loaded with chemical additives which can trigger behavioral problems (Caputo 2005). Secondly, junk food is to be said as the major contributor to litter problems. The fast food packaging causes litter problems which is a safety and health hazard, increases cleaning costs and reflects bad image to our communities (Smith 2005). Cans, crisp packets, cartons and plastic container are among of them and are everywhere (Green 2005). By reducing the sale of junk foods, litter problem in schools can be redressed (Smith 2005) as many junk foods are sold in school canteen. As a result of the reduction, the school grounds man doesn’t have to spend so long cleaning and has more time to spend on maintenance projects that benefit the school (Green 2005). Lastly, junk foods need to be banned because they are unhealthy diet because they are lack in nutritional value (Health Foundation 2005). The nutritional value of food eaten by Australian children has been falling progressively over the past 30 years and this can be linked directly to the increased availability and consumption of junk food (Tran 2005). Examples of the junk food that is low in nutritional value are biscuits, cookies, chips.

The Cities affects with Gangs The recent unrest in Baltimore raises complex and confounding questions, and in response many people have attempted to define the problem solely in terms of insurgent American racism and violent police behavior. But that is a gross oversimplification. America is not reverting to earlier racist patterns, and calling for a national conversation on race is a clich that evades the real problem we now face: on one hand, a vicious tangle of concentrated poverty, disconnected youth and a culture of violence among a small but destructive minority in the inner cities; and, on the other hand, of out-of-control law-enforcement practices abetted by a police culture that prioritizes racial profiling and violent constraint. Don’t waste time! Our writers will create an original "Correlation Between Cities And Gangs" essay for you Create order First, we need a more realistic understanding of Americas inner cities. They are socially and culturally heterogeneous, and a great majority of residents are law-abiding, God-fearing and often socially conservative. According to recent surveys, between 20 and 25 percent of their permanent residents are middle class; roughly 60 percent are solidly working class or working poor who labor incredibly hard, advocate fundamental American values and aspire to the American dream for their children. Their youth share their parents values, expend considerable social energy avoiding the violence around them and consume far fewer drugs than their white working- and middle-class counterparts, despite their disproportionate arrest and incarceration rates. In all inner-city neighborhoods, however, there is a problem minority that varies between about 12.1 percent (in San Diego, for example) and 28 percent (in Phoenix) that comes largely from the disconnected youth between ages 16 and 24. Most are not in school and are chronically out of work, though their numbers are supplemented by working- and middle-class dropouts. With few skills and a contempt for low-wage jobs, they subsist through the underground econom y of illicit trading and crime. Many belong to gangs. Their street or thug culture is real, with a configuration of norms, values and habits that are, disturbingly, rooted in a ghetto brand of core American mainstream values: hyper masculinity, the aggressive assertion and defense of respect, extreme individualism, materialism and a reverence for the gun, all inflected with a threatening vision of blackness openly embraced as the thug life. Such street culture is simply the black urban version of one of Americas most iconic traditions: the Wild West. Americas first gangsta thugs were Billy the Kid and Jesse James. In the youth thug cultures of both the Wild West and the inner cities, America sees inverted images of its own most iconic values, one through rose-tinted glass, the other through a glass, darkly. While there is some continuity between the old Western and thug cultures learned through extensive exposure to the media, that of the urban streets originated more in reaction to the long centuries of institutionalized violence against blacks during slavery and Jim Crow. The historian Roger Lane has traced the roots of Philadelphias black criminal subculture all the way back to the mid-1800s; W. E. B. Du Bois found it thoroughly entrenched in his own study of Philadelphia in the 1890s. Its intersection with overly aggressive law enforcement was not random or inevitable, but rooted in a historical irony. As the political scientist Michael Javen Fortner documents in his forthcoming work Black Silent Majority, when Gov. Nelson A. Rockefeller of New York introduced draconian new drug laws in the early 1970s to combat the increasingly violent street life of New York City, he did so with the full support of black leaders, who felt they had no choice † their lives and communities were being destroyed by the minority street gangs and drug addicts. But it was not long before the dark side of this intervention emerged: Soon all black youth, not just the delinquent minority, were being profiled as criminals, all ghetto residents were being viewed and treated with disrespect and, increasingly, police tactics relied on the use of violence as a first resort. And yet it didnt work, at least in one important respect: Although the black homicide rate has declined substantially, it still remains catastrophic, with blacks being murdered at eight times the national rate † and, among teens, it has been rising again since 2002. In tackling the present crisis, it is thus a clear mistake to focus only on police brutality, and it is fatuous to attribute it all to white racism. Black policemen were involved in both the South Carolina and Baltimore killings. Coming from the inner-city majority terrorized by the thug culture minority, they are, sadly, as likely to be brutal in their policing as white officers. We see this in stark detail in the chronic violence of New Yorks Rikers Island correction officers, the leadership and majority of whom are black. We see it also in the maternal rage of Toya Graham, the Baltimore single mom whose abusive reprimand of her son, a video of which quickly went viral, reflects both her fear of losing him to the street and her desperate, though counterproductive, mode of rearing her fatherless son. What is to be done? On the police side of the crisis, there should be immediate implementation of the sensible recommendations of President Obamas Task Force on 21st Century Policing, including more community policing; making the use of violence a last resort; greater transparency and independent investigation of all police killings; an end to racial profiling; the use of body cameras; reduced use of the police in school disputes; and fundamental changes in officer training aimed at greater knowledge of, and respect for, inner-city neighborhoods. Accompanying this should be a drastic reduction in the youth incarceration rate, which President Obama can make a dent in immediately by pardoning the many thousands of nonviolent youths who have been unfairly imprisoned and whose incarceration merely increases their likelihood of becoming violent. In regard to black youth, the government must begin the chemical detoxification of ghetto neighborhoods in light of the now well-documented relation between toxic exposure and youth criminality. Further, there should be an immediate scaling up of the many federal and state programs for children and youth that have been shown to work: child care from the prenatal to pre-K stages, such as Head Start and the nurse-family partnership program; after-school programs to keep boys from the lure of the street and to provide educational enrichment as well as badly needed male role models; community-based programs that focus on enhancing life skills and providing short-term, entry-level employment; and continued expansion of successful charter school systems. The presidents My Brothers Keeper program, now a year old, is an excellent and timely initiative that has already begun the coordination and upscaling of such successful programs, as well as the integration of the private sector in their development. And finally, there is one long-term, fundamental change that can come only from within the black community: a reduction in the number of kids born to single, usually poor, women, which now stands at 72 percent. Its consequences are grim: greatly increased risk of prolonged poverty, child abuse, educational failure and youth delinquency and violence, especially among boys, whose main reason for joining gangs is to find a family and male role models. As one gang member told an interviewer working for the sociologist Deanna Wilkinson: I grew up as looking for somebody to love me in the streets. You know, my mother was always working, my father used to be doing his thing. So I was by myself. Im here looking for some love. I aint got nobody to give me love, so I went to the streets to find love.
