...1. Según Enrique Dussel, existen varios problemas con las ciencias sociales y la modernidad, especialmente para nosotros que vivimos en el Sur. ¿Cuáles son estos problemas y qué propone Dussel? Para responder esta pregunta debemos dar un resumen de la lectura Europa, modernidad y eurocentrismo de Dussel empieza con el cambio del significado de Europa. El empieza a romper con el mito del cuento único de Europa donde tiene comienzo en los fenicios y semitas (Asia) Egipto (África) empieza a dar lugar a la historia de la Europa moderna y lo sitúa en el Oriente que es lo contrario a lo que se relata hoy en día. Dussel dice que el mito de la diacronía unilineal de Grecia, Roma y Europa, es un invento ideológico del siglo 18 el romanticismo alemán para su ideología racista del modelo “ario”. El occidental va a ar al imperio romano que ahora contiene al África del norte y esta opuesto a los reinos helenistas. Durante todo este proceso no se tiene todavía el concepto de Europa. Para el tercero el reino de Constantinopla cristiano va a se enfrenta al mundo árabe musulmán. Esto va a crear el mundo griego clásico este griego va a dar proceder el mundo romano occidental y al mundo bizantino oriental luego al mundo árabe-musulmán y judío. España y Portugal va a salir de los musulmanes y judíos que vivían en la península ibérica esto va a dar paso al descubrimiento del 1942, luego del descubrimiento de América empezaría la “Modernidad”.

...DEVELOPMENTAL BIOLOGY The right slant Cell 121, 633–644 (2005) One of the biggest questions in developmental biology is how embryos that begin as uniform balls of cells end up asymmetric. Experiments in mice provided a clue when researchers discovered that hair-like cilia protruding from embryonic cells in mice rotate, somehow setting up a flow in the surrounding fluid that defines the left–right axis. A team led by Nobutaka Hirokawa of the University of Tokyo supplies another piece of the puzzle by showing exactly how the cilia’s movement sets up the directional flow. The researchers found that the cilia rotate around an axis tilted 40 backwards. The same rotation was observed in rabbit and medakafish embryos, suggesting that the mechanism, previously studied only in mice, defines asymmetry in other vertebrates. Paraphrasing of Research Highlight: When studying developmental biology researchers found that embryos start as a uniform ball of cells, however, they were questioning why do these embryos end up asymmetric. Research experiments were done on mice, researchers found that the cilia on the embryos on mice rotate and this rotation controls the flow of the surrounding fluid explaining the left-right axis. Further research was done and the experiments showed that the rotation of the cilia on the embryo is rotated 40 degrees backward on an axis. Experiments were also made in rabbits and medakafish embryos and the rotation in the cilia was observed. These results explain...

...James Gwinn BIOL 840 Infectious Disease - Fall 16 Case Study Scenario: Earlier this week, a middle-aged man came into an urgent care facility referencing a high fever and severe chills for a couple days. He has also been experiencing muscle aches, headache, and an overall tiredness. He has not been feeling well for the past two weeks. Since the patient revealed that he did not receive a seasonal flu-shot, he was prescribed Theraflu and sent home. After a couple more days, the patient returned to the office with no improvement with additional nausea and vomiting. The doctor prescribed a simple blood test and noticed that the man was suffering from hemolytic anemia. The man is from New Hampshire and spends most of his time outdoors. He enjoys hunting, fishing, and trail-hiking. He has...

...In this experiment we were able to use the technique of Gram staining to differentiate two types of bacteria that were unknown. Gram staining is a method that is used by many scientists in order to identify unknown bacteria’s via the unique physical and chemical characteristics of their cell walls. In a gram test a bacteria can either be gram positive or gram negative. The Gram-positive bacteria have an intricate set of amino sugars which we call peptidoglycan that form a thick cell wall around the plasma membrane. On the other hand, Gram-negative bacteria have an uncomplicated cell wall which thus has less peptidoglycan. The main source of identification within the Gram test is the fact that Gram-positive bacteria appear blue-purple while Gram-negative bacteria appear pink (Gram Stain). Bacteria can come in one of three different shapes; spirilla (spiral-shaped), cocci (round-shaped), and bacilli (rod-shaped). In order to be able to see these shapes a bacteria must be stained or dyed. I hypothesis that we will have one Gram-positive culture and one Gram-negative culture. (Lab Manual) In order to prepare this lab experiment we performed five steps. The first step in preparing this experiment was to heat fix a bacteria culture sample which in return stopped the sample from coming off the slide during the experiment. In order to perform this first step we first turned on a Bunsen burner and set the flames to a blue color which was used to sterilize an inoculating loop. Next, a...

...Acids, Bases, PH Introduction. This experiment helped to understand difference between acid and base and there PH levels. We learned how to identify buffer. Buffer is substances that resist changes in PH when acid or base is added to solution. Also we learned that water is neutral. Its mean that water has an equal concentration of H and OH. PH number of water is 7. Acid’s PH numbers less than 7. Bases’ PH number is greater than 7. As well we learned how to use and calibrate PH Meter. Materials and methods. For experiment at class we used two solutions, solution A and solution B. First we took PH meter and measured PH level of solution A. After we add to solution A 1.0ml of HCl and record PH level. Total of HCl added was 10 ml, we did it by adding 1.0 ml of HCl at the time. Second time we took solution A and start adding 10 ml(1.0 ml at the time) of NaOH. With PH meter we record number changing in PH. Third time we took solution B , measured PH level and did the same steps as with solution A. Results.

...Individual Assignment 2 Instructions Attention deficit disorder (ADD) is a syndrome in which a person has difficulty focusing sustained attention on a task for a significant amount of time. In some cases this is accompanied by hyperactivity as well. It is currently being diagnosed at an all-time high. Between 1989 and 1996, youth visits for ADD increased 90%, from 1.9% of total physician visits to 3.6%. Now, a psychiatrist named Dr. Edward Hallowell is making a new distinction. He has described a similar set of characteristics in a large number of patients that he terms Attention Deficit Trait (ADT). It looks a lot like ADD in its day-to-day manifestation, but unlike ADD, ADT symptoms lessen when the sufferer goes on vacation or into a decreased sensory input setting for an extended time period (on the order of days or weeks). In such a long-term placid situation, the ADD sufferer’s problems continue unabated. Imagine that you have the general set of symptoms described above. But which of the two syndromes are causing your symptoms: the disorder (ADD) or the trait (ADT)? Approach your problem using scientific methodology—developing a question, a hypothesis, an experiment, and a control for the experiment. The initial question and the experiment that will be performed on you are provided. Your job is to state the hypothesis and to design the most important and most basic control for this experiment. Your Question: What’s my problem? Is it ADD or ADT? 1. Your...
