Biochemistry at its finest!

Biochemistry at its finest! Yesterday, I attended my last 7.05 (Biochemistry) lecture taught by Prof. Michael Yaffe. Three professors co-teach the class and Yaffe taught for the first month of the semester. Indeed, it was a sad day. For 1.5 hours three times a week, hundreds of students fill 10-250 (one of the giant lecture halls) to watch Yaffe cover crazy amounts of information in very little time. By the end of every lecture, you probably have four pages of very colorful notes and 9 boards filled with pretty picture of molecules and processes. The picture below is what the board looked like last Friday: Using these boards, Prof. Yaffe explained the metabolic process that prevents you from bleeding to death after a measly paper cut! Basically, everyone knows that when a blood vessel is damaged, a bunch of platelets congregate to repair the cut by creating a clot. What you may not know is that this process is facilitated by the formation of a mesh made out of a protein called fibrin. This fibrin is formed by a long and relatively complicated process (called a coagulation cascade). The cascade begins with a vascular injury (a cut) that initiates an extrinsic pathway (aptly named because the source is outside of your body), which initiates an intrinsic pathway (named such since all of the necessary components already exist in your circulatory system). In the end, this complex process results in a reaction at the right place at the right time unless you have something like hemophilia. (Dont continue reading this if you plan on taking 7.05 and dont want the surprise to be ruined!) Thats all well and good, but the *craziness* began when Yaffe asked if anyone wanted to donate blood for a demonstration. I thought he was joking and nobody volunteered. So, he called up the head TA (teaching assistant) and the TA dutifully sat in a chair at the front of the classroom as Yaffe pulled out rubber gloves, a syringe, and some tubes. He drew a considerable amount of blood (2 vials full), while everyone watched in awe (except for the ones who had heard about it before, they seemed more amused from everyone elses reaction). Then, he added a clotting factor to one tube and continued with class. An hour later, he showed that one tube had a huge clot in it, while the other was the same as before. By the way, Yaffe is an MD/PhD who studies protein-protein interactions and signal transduction pathways by lipid and protein phosphorylation. His lab is in the Center for Cancer Research, where I did my first UROP (well, not in his lab in particular, just in the same building.) Im sure he would draw your blood, too, if you asked politely.

The Core Focus Of The Prison Officer - 1559 Words

This statement, that rule enforcement is the core focus of the prison officers job, is underestimating the challenges and risks that come with being a prison officer. Research shows that there is more pressure on the officers than to just administer the rules, they are dealing with human beings who have a range of emotional and daily challenges they must overcome in prison. A prison officer has daily contact with these prisoners which is why rules cannot be fully implemented, all the time. â€Å"†¦guard buys compliance or obedience at the cost of tolerating disobedience† (Sykes 1958, p.57). They were created to guide the officers, there are numerous elements that are equally or in some cases more important that enforcing specific prison rules.†¦show more content†¦Comparing prisoner experience and opinions of prison officers between the two institutions, harsh rule enforcement shows to be detrimental to the prisoners self-respect but causes hostility with the reg ime.. A prisoner in Albany, a category B prison states that â€Å" most of [institution] rules are not designed for any specific purpose other than for bashing you over the head every day of the week to remind you your in prison† (ibid, p.191). Inmates are being controlled and dictated forcefully, with no input into their regime. This shows that with no social agreement or relationship between inmate and staff, inmates are being punished in an inequitable manner, by the unethical abuse to dominate. Jeweks states that ‘total domination over prisoners is fiction’ (2007, p.124), that prisoners will have no sense of internal duty to comply to the officers. Long Lartin, a category A prison on the Isle of White, proposes a sense of confidence in the prisoners, as they have privileges that most prisons do not have, for example; a generous gym, allowing prisoners outdoors during summer nights, ownership of clothes and no escorts needed (Sparks, Bottoms and Hay, 1996, p. 171). â€Å"If they treat you like an animal or a lump of wood, you act like one. If they treat you like a human being, you behave like a human being† (ibid p.172).

Zinn Chapter 12 Response the Empire and the People Essay Example

Zinn Chapter 12 Response: the Empire and the People Paper In chapter twelve of Howard Zinn’s A People’s History of the United States, he talks about the history of expansion in the United States, which helped shape America. People, such as Theodore Roosevelt and Captain A. T. Mahan of the U. S. navy, wanted expansion brought upon America. Mahan used propaganda to influence other powerful leaders within the United States. Commercial farmers began to demand expansion in the United States. Manufactured goods were becoming overproduced in America, so the need for foreign markets and trade became prominent. By 1893, America was the second largest trading country. Theodore Roosevelt welcomed war as a means for expansion overseas. According to Zinn, President Roosevelt wrote to a friend in the year 1897: â€Å"In the strict confidence . . . I should welcome almost any war, for I think this country needs one. † The movement towards expansion was popular among the upper class Americans (military men, politicians, businessmen, etc. ). Howard Zinn stated that many people, like philosopher William James, thought that Roosevelt obsessed over war and treated peace as a condition of blubberlike and swollen ignobility. President Roosevelt was conscious of America’s trade with China. American trade and influence was an important key to shaping American policy in the Asian countries. America became greatly interested in helping Cuba as an appeal of expansion during the reign of Cleveland and McKinley as presidents. Cuba was at a revolt against the Spaniards for independence during the time. Americans gave Cuba popular support because they were fighting for liberation. There was fear that Cuba might turn into a black republic similar to Haiti.

S. battleship Maine, a representation of the interest in Cuba, was destroyed by an unknown explosion. President McKinley did not want war, but was moving towards that direction, Zinn exclaimed. After a long battle, Cuba became a part of America. The Filipinos rose up in a bloody revolution against America for their independence, which would take America three years to overcome and crush. Angered African American soldiers deserted American troops and joined with the Filipinos. They were furious because the term â€Å"nigger† was used by the white troops. Posters were used by the Filipinos as a way to lure the black soldiers in their direction and fight against the white American troops. Back in the United States, the African- Americans of Massachusetts wrote a letter to President McKinley addressing their overlooked unfair treatment. In the years to come, the American people would become impatient and unpatriotic because of the attention that was being turned towards issues outside of America.

menkaure essays

menkaure essays The sculpture group of King Menkaure and His Queen is positioned in one of the basic types of Egyptian sculpture the Standing/Striding pose. The figure of Menkaure is rigidly frontal, although his head is slightly turned to the right. His left foot is slightly advanced, however the upper body does not respond to this uneven distribution of weight - there is no tilt in the shoulders, nor a shift in the hips. All movement of the figure is suppressed: his muscular arms hang down his athletic body, they are not flexed at the elbow and do not break through the front contour of his thighs. The body remains wedded to the block of stone from which it was carved. The artist does not remove the dead stone between the arms and torso and most importantly his advanced leg is not carved in the round, which contributes to the solid and majestic appearance of the statue. The Queen assumes the same rigidly frontal posture, however her left leg is less advanced than his, which alludes that she is a subordinate figure to her king in this stance she is just echoing the pharaohs decisive actions. She embraces the pharaoh with her right arm placing her hand around his waist; her left arm is bent at the elbow and covering her stomach rests on the kings left arm. There is a space of about couple of centimeters between the statues that widens towards the base, and which makes Menkaure appear standing independently from his female counterpart. In this frontal, striding forward posture the pharaoh looks confident and in control. ...

Prophetic, Predictive, Presageful, and Portentous

Prophetic, Predictive, Presageful, and Portentous Prophetic, Predictive, Presageful, and Portentous Prophetic, Predictive, Presageful, and Portentous By Maeve Maddox A reader has asked me to explain the differences between prophetic, predictive, presageful, and portentous. In a very general sense, the words are synonymous. All four are adjectives indicative of the future. Their connotations, however, differ. The adjective prophetic has two meanings: 1. prophetic: â€Å"characteristic of prophecy or a prophet.† For example, King Saul was known to fall into a â€Å"prophetic frenzy,† a mental state usually associated with a prophet. 2. prophetic: â€Å"foretelling events.† For example, Jules Verne (1828-1905) created fictional scenarios that have proved to be prophetic of events and discoveries in our own times. Prophetic often conveys supernatural connotations. The adjective predictive is a simple way to say that something can be predicted or foretold. For example, anyone who has ever browsed an investment flyer has come across this expression: â€Å"Past performance is not predictive of future success.† The adjective presageful derives from the noun presage: â€Å"something that portends, foreshows, or gives warning of that which is about to happen.† Presageful means, â€Å"full of presage.† The verb presage means, â€Å"to predict.† I found this example on a site dedicated to prison reform: â€Å"Two decades after [a former warden’s] presageful caveat, the Louisiana penal system is imploding under the weight of a burgeoning inmate population and a societal mindset that is more retributive than rehabilitational.† Presageful is so uncommon that Word’s spellchecker flags it as a misspelling. Merriam-Webster’s single citation- â€Å"presageful gloom†- is from a convoluted sentence of 101 words spoken by Merlin’s sweetheart Vivien in Tennyson’s Idylls of the King. Trust me, this is a word you can do without. The adjective portentous is used with three meanings: 1. portentous: â€Å"relating to a portent.† A portent is a sign thought to predict the future. Etruscans studied the  flight of birds  to foretell the future. Even the number of  birds  was regarded as  portentous. 2. portentous: â€Å"eliciting amazement.† A travel article contains this example: â€Å"In the Grand Forks Valley at the foot of the mountain the portentous wall cuts off entirely the view of the summit.† 3. portentous: â€Å"exhibiting gravity or ponderousness.† A New York Times reviewer uses the word in the sense of inflated or pompous writing: â€Å"To be sure, there were plenty of passages like this in Cold Mountain - prose that somehow managed to be simultaneously portentous, folksy and cloying, like banjo music on the soundtrack of a Ken Burns documentary.†Ã‚   Used with the first meaning given above, portentous often suggests that whatever is being foretold is ominous and to be feared. A Google search of the four words gives the following results: predictive: 44,700,000 prophetic: 17,800,000 portentous: 464,000 presageful: 15,300 The Ngram Viewer shows that predictive and prophetic are far more common than portentous or presageful in printed books. English has so many words that refer to foretelling the future or knowing something without being told that no writer need be at a loss to choose exactly the right one. For example: clairvoyant divinatory farseeing farsighted insightful intuitive perceptive percipient prescient prognostic psychic vatic visionary Here are a few synonyms for portentous: foreboding ill omened inauspicious menacing ominous premonitory threatening unfavorable Want to improve your English in five minutes a day?
