Dinosaurs: Warm-Blooded?
There is presently much controversy regarding the issue of dinosaurs, as the fact that experts have access to a limited amount of resources concerning this matter makes it difficult for them to express certainties concerning this particular animal reign. Even with the fact that there are presently no living dinosaurs to be dissected, scientists have come up with a series of theories based on how dinosaurs behaved. In spite of their physiology, most dinosaurs put across behavior characteristic to mammals and birds. One of the oldest debates in the history of dinosaur studies is related to the blood temperatures of these creatures, as some experts insist that they were cold-blooded while others maintain that they were warm-blooded. The presence of dinosaur fossils at high altitudes makes it possible for one to consider that dinosaurs were warm-blooded, taking into account that cold-blooded creatures typically evolve in warm areas.
All living bodies on earth depend on a series of chemical reactions in order to survive and each particular reaction is most effective when it is presented with an optimal temperature. Living mammals and many other animals have internal apparatuses that control temperature levels and that provide the best temperature needed in order for certain chemical reactions to occur. Chemical processes usually...
Blood Spatter The television show Dexter highlights the role of blood spatter analysis in forensics and law enforcement work. Blood spatter analysis can be a cornerstone of crime solving. Rooted in the laws of physics, blood spatter analysis provides a method by which the forensic scientist can recreate a crime scene to provide law enforcement with valuable crime solving tools. Blood spatter can reveal incidents that occurred before, during, and after
Blood doping, as a performance enhancing method, has been around for more than three decades now. The Finnish athlete and the four time Olympic gold medallist, Lasse Viren is widely regarded as the first successful user of Blood doping to achieve sporting success. However, only much later after the 1972 and 1976 Olympic success, it was determined that Lasse Viren had used blood doping to boost his performance. [The Gale
This shows that monitoring of lifestyle changes can effectively be implemented in conjunction with other drug therapies to provide the most effective results for patients in need. Additionally, another 2010 (Navidian et al.) study showed that although lifestyle monitoring may not have been much different in terms of systolic blood pressure, there were statistical differences in terms of diastolic blood pressure. In this study, 61 patients with systolic hypertension
Blood Transfusion The Pros and Cons of Blood Transfusion A blood transfusion poses both risks and benefits and, therefore, there are pros and cons to be weighed before opting for a blood transfusion. What a blood transfusion does is allow blood products to be replaced in a human body that has lost its own blood products through either illness or accident. The pro-of undergoing a blood transfusion when in danger of death
Blood Substitutes The search for the perfect substitute for human blood began as early as the 17th century, when water, oil, milk and animal blood were used for transfusion until the first human-to-human transfusion in Philadelphia in 1795 (McCarthy 2003). Successes were, however, inconstant since then, as patients died due to injuries or from reactions to foreign blood, so that it was only a last resort during emergencies. Early in the
(Janine Roberts 2006) Acts like the Kimberley process are presumed to guarantee that the diamonds that people buy have not been related to the killing and mutilating of children from a South African country. However, as most critics state, the certification alone is not enough to guarantee such a thing. The process of providing guarantees that the diamonds have not been mined by rebels needs to be much more complex.
