Twinning In Cattle :: essays research papers fc

Twinning in Cattle   Ã‚  Ã‚  Ã‚  Ã‚  Due to the continual fluctuation of the cattle market cattle producers have been searching for ways to improve their production and increase their profits any way possible. For years genetic engineers have been working hard on improving economic efficiency in cattle. It is their hope that through genetic research they can improve the yield and the income of cattle producers around the world. Research has shown that twinning is one way that farmers can increase their yield . Twinning has a significant influence on producers as well as people who are involved in all realms of agriculture. The reason for this large impact at this time is the fact that the occurrences are limited. However, many producers have a vision that twinning can be more than a once in a blue moon occurrence. These producers see twinning as a way to dramatically increase their yield per calving season. Producers will increase their income due to more weight per year per cow. It is necessary ;however, that the producer be well educated on how to handle twinning, in order for it to be successful for them.   Ã‚  Ã‚  Ã‚  Ã‚  Many agencies see twinning as an economic move upward. The American Breeder Service has made efforts to produce semen as well as embryos with high predicted breeding values available to producers. They have been recorded based on twinning probabilities and ovulation rates. A large amount of work on twinning has also been done by the Meat and Animal Research Center. Since the early eighties, they have located cattle with a high frequency of twinning and been forming a breeding foundation based on this characteristic. â€Å"We believe the time has come to make some of these unique genetic resources available to the beef industry through artificial insemination and embryo transfer† (Gregory 23). An extensive amount of research has been done using embryo transfer in cattle. In one study recipients were implanted with either a single embryo, two embryo in one uterine horn, or one embryo in each uterine horn. It is also possible to split embryos using a micro manipulator and implant each half to produce identical twins. On the average about 16% of the cows implanted with two embryos produced twins. When two embryos were implanted, and one was placed in each horn, conception rates were comparable with the prior method, however the twinning rate was much higher when the embryos were in separate horns (73% vs. 45%). For the most part, when one embryo was split in an attempt to produce identical twins, only one of the offspring survived birth (Davis 302).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Many producers see twinning as a possible advancement in

My First Experience in College

Glass Castle The Glass Castle was written by the author, Jeanette Walls and she is also the protagonist of the book. The book tells the story of Jeanette Walls and her family life. It shows how they basically struggled day in and out like being short on food and money, they always moved around the country just to find a place to settle in. Jeanette Walls and her family mostly lived in various mining towns on the west coast of America.As Jeannette grew up in the desert, she enchanted by the limitless bounds of nature and the fantasies her father dreams up for her and her siblings. When Jeanette lived in the desert with her brother (Brian), she usually stacked up a rock collection and explored the natural and man-made features of the environment. Due to Rex Alcoholism, life in the desert ended because the family ran out of funds. So from the desert, they decided to relocate to Welch where Rex grew up.One thing I mostly knew about the Walls family was that their parents were both addict ed to substances that could kill, their father was addicted to alcohol while their mum was so addicted to sugar and it lead to them not paying attention to their children. On my academic research, the article I researched was on alcoholism and it basically said alcohol consumption, particularly heavier drinking is an important risk factor many health problems and, thus, is a major contributor to the global burden of disease.When it comes to Rex, the head of the Walls family, he tends to focus more drinking than his family which led to him being terribly poor. However, life in Welch, West Virginia is completely different than the life the Walls led in the desert on the West coast. Most notably, Welch has a winter season which brings new challenges to the Walls family. From their arrival, the Wells children are itching to leave Welch and return to the desert. But eventually circumstances become so bad that they realize they must move away from their parents in order to achieve stable lives.Lori and Jeannette set their sights on New York and begin saving money to move out of Welch once and for all. Moreover, Walls describes in fascinating detail what it was to be a child in this family, from the embarrassing (wearing shoes held together with safety pins; using markers to color her skin in an effort to camouflage holes in her pants) to the horrific (being told, after a creepy uncle pleasured himself in close proximity, that sexual assault is a crime of perception; and being pimped by er father at a bar). Though Walls has well earned the right to complain, at no point does she play the victim. In fact, Walls’ removed, nonjudgmental stance is initially startling, since many of the circumstances she describes could be categorized as abusive (and unquestioningly neglectful). But on the contrary, Walls respects her parents’ knack for making hardships feel like adventures and her love for them–despite their overwhelming self-absorption–resona tes from cover to cover.Eventually the siblings all end up relocating from Welch to New York in an attempt to be liberated from the stifling environment in Welch. For a time everyone is settled and living independently until Rex and Rose Mary show up in Manhattan in a van. After just a short while, the couple ends up poor and homeless once again and despite their efforts, the children are unable to take on the burden of hosting their parents anymore.Consequently, Rose Mary and Rex become squatters in abandoned apartments until Rex dies after having a heart attack. To Conclude, Jeannette has finally reconciled her past and present and no longer feels the need to hide behind lies or half-truths. In my perspective, I feel Glass Castle has thought me a lesson and that is to take life serious not for a mere joke and that is why Rex died through ignoring the clean aspect of life. The memoir liberates her and allows her to do what she enjoys most about writing; communicate with the world.

The Relevance of Behavioral Psychology to Instructional...

The Relevance of Behavioral Psychology to Instructional Technology Behavioral Psychology Defined John Watson wrote a paper in the Psychological Review in 1913 and defined behavioral psychology or behaviorism as †¦a purely objective experimental branch of natural science. Its theoretical goal is the prediction and control of behavior. Introspection forms no essential part of its methods, nor is the scientific value of its data dependent upon the readiness with which they lend themselves to interpretation in terms of consciousness. The behaviorist in his efforts to get a unitary scheme of animal response recognizes no dividing line between man and brute (Reynolds, Sinatra, Jetton 95). Essentially Watson’s views supported the†¦show more content†¦Lastly the concept of functionalism states when people think or act they do so for a purpose or function(Alberto Troutman 30). Thus behavioral psychology becomes a science emphasizing a practical and observable approach (Alberto Troutman 30). There are many behavioral psychologists that have contributed to the field. John Watson’s definition provided the foundation for Ivan Pavlov and B.F. Skinner. Their work has been extremely beneficial to the development of psychology and education. Ivan Pavlov earned a Nobel Peace Price for his research on respondent conditioning. It was by chance that this discovery was made. He was studying the behavior of dogs in his laboratory. If his assistant who fed the dogs came into the laboratory when Pavlov was studying the dog’s stomach, the dog began to secrete gastric liquids, just as if they had been given food. Pavlov deemed this a psychic secretion and noted that this reaction affected the whole digestive system, starting with the flow of saliva in the mouth as well as the secretion of acids in the stomach(Alberto Troutman 31). His peers discouraged him from pursuing this research, but he continued. His experiment involving the dogs included pairing food powder (which starts salivation-an automatic reflex) with a tone or noise that would normally have no affect on a dog’sShow MoreRelatedChildhood Obesity Essay976 Words   |  4 Pageslecture style, core information with the learning styles and technology skills of today’s 21st century learners, the Net Generation.

Back Titration in Chemistry

A back titration is a titration method where the concentration of an analyte is determined by reacting it with a known amount of excess reagent. The remaining excess reagent is then titrated with another, second reagent. The second titrations result shows how much of the excess reagent was used in the first titration, thus allowing the original analytes concentration to be calculated. A back titration may also be called an indirect titration. When Is a Back Titration Used? A back titration is used when the molar concentration of an excess reactant  is known, but the need exists to determine the strength or concentration of an analyte. Back titration is typically applied in acid-base titrations: When the acid or (more commonly) base is an insoluble salt (e.g., calcium carbonate) When direct titration endpoint would be hard to discern (e.g., weak acid and weak base titration) When the reaction occurs very slowly Back titrations are applied, more generally, when the endpoint is easier to see than with a normal titration, which applies to some precipitation reactions. How Is a Back Titration Performed? Two steps are typically followed in a back titration: The volatile analyte is permitted to react with an excess reagent A titration is conducted on the remaining quantity of the known solution This is a way to measure the amount consumed by the analyte, thus calculate the excess quantity.

Buffalo film review Free Essays

Do you want to fragrantly waste a mind-numbing hour and a half of your monotonous life? If you just threw you hand up in the air and shouted yes’, then Vincent Gallon’s film Buffalo ’66 is for you. You will be subjected to a remarkably mundane plot, which will leave you hopelessly confused and a little afraid. It’s only rendering feature is, perhaps, the artistic style in which it is created. We will write a custom essay sample on Buffalo film review or any similar topic only for you Order Now The film Is set In the overly Industrialized town of Buffalo where our mall character, Billy Brown. Who Is played might say, badly by Gallo himself, was born with regret ND raised with disinterest. We are fist introduced to Billy as he is being released from prison. We become reluctant voyeurs of his life. His first problem that he had to face after being released is searching for a bathroom. Yes! You real that right. For the first maybe 20 minutes of the film, he is running around in his bright red boots, and ill fitted clothes, looking quite Like a child holding his genitals searching for a place to relive himself. I really don’t understand the meaning of this either. But what an entrance to a movie. Throughout his hunt for a restroom, we are introduced to Lay. Gallo has decided to put her in a virgin blue dress, a doll like face and alienated from the rest of her dance class. In fact she looks very much like a prostitute. Gallo chooses to sexuality her, focusing the camera around her breasts. Maybe this is why Billy kidnaps her. Yes! I said kidnaps. Told you this was a weird movie. Well Billy makes Lay drive him to his parents house, because he can not ‘drive a stick, but along the way he makes her pull over so he can relieve himself behind a tree. Any normal person would have Just driven off and got the hell out of there. But Lay is not normal, she is alienated from society because of her lack of lets call it social skills. She decides to stay, and continue being kidnapped. Apparently his playground talk of ‘If you do this for me, I will be your best friend, you will be the best friend I have ever had’. However if we gallantly ignore this entire aimless and dreary plot all we have left is Gallon’s amazing use of techniques such as his use of colors, music and camera angles. Throughout Buffalo ’66, Gallo focuses on the abundant use of pale colors and lurid scenes, which portray a lonely sense of emotion and feeling. Gallo an accomplished musician composed a very suitable score to accompany the film. Having himself creating most of the songs Gallo was able to carefully control a great deal of the mood and feeling of each scene. His song ‘Lonely Boy playing at the start of the movie in the opening credits, starting when the Billy Picture is shown Is a good example of child in the picture. Another technique is Gallon’s use of overlaying images or videos over the top of the already playing film. He does this to show flashbacks to inform us of Billy’s past. Through these flashbacks we discover that Billy’s childhood was very harsh. We see his loss of innocence through his Fathers anger on his dog Bingo, and his Mothers lack of care when Billy has an allergic reaction to chocolate. We also see his innocence in the events that sent him to prison. With Billy’s Mothers obsession with the town’s local football team the ‘Buffalo Bills’, we see her lack of care in Billy as a child again. When Lay asks Billy’s mum to see a photo of Billy as a child, She then replies to husband â€Å"Where’s the Billy Picture? † He had one picture as a kid, ONE!! But as you walk into the house you see a bunch of pictures of Buffalo players. This is a major key to Billy’s alienation. He didn’t have a normal home and was treated like he wasn’t wanted. You will quickly grow tiered of Bill’s need to constantly repeat everything he says. You will find yourself getting frustrated and wishing you could somehow reach into the film and bring him to his senses, perhaps by rearranging his facial features. In the bowling ally scene we notice we see Billy and Lay in the photo booth, â€Å"Spanning time† together, Just â€Å"Spanning time†. At this point I found my self shouting at the screen telling him to Just â€Å"shut up†. One important event in the film is the scene between Billy and Lay in the hotel room. We witness them laying on a bed together and Billy looks very, well, uncomfortable, while Lay looks like she has been in this type of situation many times before. We have a bird’s eye view of this whole scene so we see every movement that is made. Slowly, very slowly Lay’s hand moves towards Billy’s, leaving them awkwardly holding hands, well touching hands. After what seems like an incessant amount of time, Billy rolls over, out of his very what must be uncomfortable position and him and Lay kiss. KISS! You heard me right. I thought it was Lay’s imagination to be honest. If you think it couldn’t get more awkward he curls up in the fetal position in Lay’s arms. WEIRD! But this does portray Billy’s childlike behavior again and his need for affection that his parents lacked to provide for him. I think I was thankful at this point in the movie though, because finally, finally, they ended up together. They are not alone anymore, because they have each other. Bit click ©, but never mind that. If forced to offer a quick summery of the film, I would answer in a forceful honesty, hat it is Just plain boring. So bleak and uneventful is the plot, that I would rather go bird watching. It’s only rendering features is Gallon’s cinematic techniques. There, in my view, are the movies great strength and manage to Just salvage it from complete ruin. So masterful is Gallon’s use of cinema that I should recommend this film to English school teachers and others that appreciate the subtle and obscure artistic works. To the rest of us, I would issue a warning to avoid the film, like stay at least give it 5 stars out of 10. How to cite Buffalo film review, Papers

The Change of the American Family free essay sample

The American family has changed dramatically over the past 50 years. During the 1950s, the Cleavers on the television show â€Å"Leave it to beaver† epitomized the American family. In 1960, over 70 percent of all American households were like the Cleavers: made up of a breadwinner father, a homemaker mother, and their kids. Today much of the recent research indicates the traditional American family is not a model anymore in the sense that, there is no ideal or normal family. Family is now defined by some sociologists as, â€Å"a unit comprising two or more people who share a residence for a substantial period of time and have legal or moral responsibilities for long term care for each other (our social world p287). As time passes we evolve with all the changes in our society and people are living and thinking how they feel instead of keeping up with the values and morals society once followed. We will write a custom essay sample on The Change of the American Family or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Each of us has a concept of the typical family and how it has changed overtime. Being rooted in our own family experience and community, our views are seldom, if ever, an accurate depiction of the typical family. It is fair to say that there is no such thing as the â€Å"typical† family. In our nation the characteristics of families vary dramatically by race and ethnicity, age and income of adult members of the family; religious affiliation; region of the country; and by the demographic, social, and economic factors (monthly labor review p4). One change that has affected the modern American family is Divorce. Back then divorce was uncommon. Single parent households were very rare. The last 50 years have seen a dramatic rise in divorce (the u. s has the highest in any industrialized nation), cohabitation rather than marriage, blended families of both gay and heterosexual design, and children born out of wedlock. Another change that has affected the modern American family is immigration. Immigration has changed the modern family from what America has considered the normal type, too many different races and families. Interracial couples have become more accepted over the years, as it was once viewed as wrong and what caused a lot of racial bigotry and crimes of hate becoming more prominent, but in these times it is much more accepted. Our society has evolved and has become more accepting of the new ideas in what family is. The rise of dual career, two income marriages have transformed from time. More American women are employed now as so to their husbands. While husbands are more involved in child bearing, the bulk of the housework and parenting still falls on the woman. It becomes a balancing act between care-giving demands, spousal engagement and job responsibilities. Self-definition can become a heavy burden when there is no one to come home to. Today people are able to make choices now, than back then they couldn’t due to fear of judgment from others or because of religious belief etc. with our choices and things like rational theory these changes have become more prominent. After all rational theory happens when â€Å"the costs outweigh the rewards† (our social world pg290).
