2. Explain and critically evaluate Zimmerman’s response to relativity-based arguments against presentism. Optional: compare and contrast Zimmerman’s response with Markosian’s response. Zimmerman defends the A-theory of time against allegations of B-theorists that it is in conflict with the Special Theory of Relativity (STR) and the General Theory of Relativity (GTR). He agrees that if there is conflict between the two, then it does indeed cause trouble for the A-theory. The B-Theory of time,…

Case study one 1. Principle of APTT: Platelet poor plasma (PPP) is incubated at 37 degrees Celsius then phospholipid (cephalin) and a contact activator (e.g.: Kaolin, ellagic acid) are added followed by calcium (all pre-warmed to 37 degrees Celsius). Addition of calcium initiates clotting and timing begins. The APTT measures the time required to regenerate thrombin and fibrin polymers via the intrinsic and common pathways. Reagents:  Platelet poor plasma (PPP)  Surface activator: example;…

Introduction Drosophila melanogaster can be considered model organisms for the study of genetics. Some characteristics that contribute to this status are their quick lifecycles, large amount of offspring, and the presence of only four chromosomes. Drosophila melanogaster contain bristles on the thorax, head, legs, and abdomen. These bristles are used as a sensory mechanism, allowing fruit flies to detect their surroundings as they fly and walk around their environment (Yehuda, 2011). The rate…

PURPOSE The purpose of this study is to measure object recognition testing on sleep/wake rats that measures in a streptozotocin-induced rat model of Sporadic Alzheimer’s disease. I will be focusing on object recognition testing in mice where they have the ability to perceive certain objects by its physical features such as color, shape, size, texture to determine how your short-term memory works when one or two different objects are placed for a certain period of time. The term “object…

5.11 Coronary ligation model of mice In murine models of MI or ischemic injury, permanent or temporary occlusion of the left main descending coronary artery by coronary ligation is performed [65, 73]. Coronary ligation model requires excellent techniques and anaesthesia, so large-scale experiments are very difficult to perform. The problem with this model is that artificial effects from the operation and anaesthesia cannot be avoided and it does not have atherosclerotic lesions. The standard…

Introduction: Herpes Labialis, also known as the cold sore, is characterized by painful clusters of clear blisters on or around the mouth, and is often accompanied with fever. The disease is usually caused by the virus HSV-1, or herpes simplex type 1, but can also be caused by HSV-2. In a previous study, it was found that 67.6% of Americans possessed antibodies for HSV-1, establishing HSV-1 as an exceptionally prevalent virus even in developed countries 9. The virus is spread through skin to…

Seein’ the Real Monsters by Genevieve Fernandes A couple weeks had passed since Jem had broken his arm, or rather, since Mr. Ewell had broken it for him. He had spent most of his days sleeping in his thin, white cot, surrounded by books, papers, pens and a few toys, courtesy of Atticus. In the beginning, Jem was restless and pleaded with Atticus to let him go outside, but Atticus was adamant that he stay in bed and entertain himself with what he had. Atticus reckoned that he needed more than two…

Concerning nanotechnological consumer products, the most rapidly growing is the use of nanoparticles (NPs).(47) So far the knowledge regarding the safety aspects of NPs is still in its initial phase and greater efforts is needed to understand the interaction of NPs with the human body. (48) Several studies have reported that NPs always showed more serious toxicity than bulks and suggested that their size and the dose were the key factors influencing NPs toxic effects.(49) Despite of this, large…

Silicosis, a life threatening lung disease that can severely harm your ability to breathe. Starting in 1955, the Berkeley Pit became well known as a large truck-operated, open-air copper mine in Butte Montana. The unusually high copper prices resulted in the Anaconda Copper Mining Company opening many pit mines, including the Berkeley Pit. Buying up two communities and a lot of Butte’s previous population, the company was able to clear out a pit site. But after the discovery of very acidic…
