- Electrocardiogram - 797 words
Electrocardiogram Electrocardiogram Lab Introduction Electrocardiograms are used to obtain information about the function of the heart. An ECG is a recording of the electrical activity of the heart made from electrodes placed on the surface of the skin. Salt solutions are good conductors of electricity and can transfer electrical activity to the skins surface. An ECG tracing shows the sum of the electrical potentials generated by all the cells of the heart at any moment (Silverthorn, 1998). Each point reflects depolarization or repolarization of a portion of the heart. Depolarization is the signal for contraction. There are three major components of an ECG: the p waves, which corresponds to ...

- Electrophoresis Separation Of Proteins Cytochrome C, Myoglobin, Hemoglobin, And Serum Albumin By Using Isoelectric Focusing S - 1,418 words
Electrophoresis Separation Of Proteins Cytochrome C, Myoglobin, Hemoglobin, And Serum Albumin By Using Isoelectric Focusing System (Ief) Electrophoresis Separation of Proteins Cytochrome C, Myoglobin, Hemoglobin, and Serum Albumin by Using Isoelectric Focusing System (IEF) Introduction Proteins are composed of amino acids. All amino acids are amphoteric molecules consisting of three types of amino acids: neutral, acidic, and basic. Thus, for any protein there is a characteristic pH, called the isoelectric point (pI), at which the protein has no net charge and therefore will not move in the electric field. Electrophoresis takes advantage of this characteristic. Proteins are electrophoreased, ...

- Female Versus Male Recovery Rate - 618 words
Female Versus Male Recovery Rate THE RECOVERY RATE OF THE MALE IS SIGNIFICANTLY FASTER THAN THAT OF THE FEMALE. Abstract: This experiment is designed to test whether or not gender is a major contributing factor to the recovery heart rate in humans. Most would assume that the male heart rate would be considerably faster in recovery time than that of the female. This experiment furthers that assumption by eliminating uncontrolled variables such as age, build, and health conditions. Introduction: The male human has always had certain physical advantages over the female human such as increased muscle mass, larger bones, and superb aggressiveness in times where deemed necessary. But is recovery r ...

INTRODUCTION: By controlling the type of music that a person listened to I believed that the music would help to shape what animal a person perceived the music to best represent. Due to the large array of animals, I anticipated that I would need to classify the animals into two groups: carnivores and herbivores. In addition, I assumed that the group herbivore1 would be present in both groups. There are many different kinds of music in our society. Music affects many people's lives. This can be seen through people's clothes, appearance, and actions. Furthermore, the type of music a person listens to can effect their actions. At a rock concert, one would see people crowd surfing, moshing, and ...

Laminitis In Horses Laminitis in Horses ABSTRACT: Laminitis is a painful and serious disease that can cause lameness in horses. It is an inflammation of the laminae. The Laminae is tissue that connects coffin bone and the wall of the hoof. Laminitis can occur in any horse, usually obese horses, and ponies. It is caused by changes of horses' feed, lush grass, retained placenta, intake of cold water while horse is still hot, surgery, trauma to the hoof, riding on hard ground. Key Words: Laminitis, Laminae, Inflammation, Founder, Coffin Bone Introduction: Laminitis can occur in all horses. Ponies are more prone to laminitis, just as obese horses. A horse that has had too much grain intake recen ...

pH Lab Experiment By Jeff Price Biology 101- 011 Dr. Art Ellis 1 May 1997 Trident Technical College Charleston, South Carolina 29423 pH Lab Experiment Abstract: Upon hypothesizing that stomach medicines are useful in neutralizing the acidic affects of beverages when used properly an experiment was designed to test this theory. The experiment incorporated the use of white grape juice to be the acid, Maalox as the antacid, and red cabbage juice as the pH indicator. A control group was also formulated by substituting distilled water for the antacids. After mixing the solutions in separate test tubes, any changes were recorded. These changes were the indicators for the pH level of the mixture. T ...

Science Period 1 Radishes Respond to music Phillip Chiu, Period 1 Introduction The question I will be addressing is "Does music affect radish growth?" This seemed like a good idea to research and experiment on because I wanted to know if a plant could really "hear" or if vibrations through the air, which is sound, really affects the growth of the plant. I will be testing this using different types of music including rock, jazz, and classical music. The radish (raphanus sativus), a root crops which is very easy to grow. Radishes are cold hardy but cannot withstand heat. In the South, they grow in the fall through spring, and in the North, they grow well in the spring or fall. Some interesting ...

- Stereotypes Of Men In Advertisements - 1,207 words
Stereotypes Of Men In Advertisements Visual representation of reality, as seen through mass media, is acknowledged by sociologists to be influential in shaping people's views of the world. Our everyday realities are articulated mostly by what we see in the media. The role of advertising in this interpretation of reality is crucial. The target audience's self-identification with the images being a basic prerequisite for an advertisement's effectiveness, makes advertising one of the most important factors in the building of behavior models and values systems. The way a certain notion is managed at a visual level determines how people will perceive this notion and whether they will identify wit ...

They also noted that the "American murder rates for handguns are higher than the total Canadian homicide rate"(249). According to Sproule and Kennett, "Canada's favourable situation regarding murder relative to the United States is to a large measure the result of Canadian gun control, and Canadians must be vigilant against any erosion of our gun control provisions" (250). B) Comparison: The works cited above are based on research done by experts and scholars in the field of gun control and violence. Examining the above materials can identify similarities and differences found in the va ...

THE RESUMPTION OF WHALING BY NORWAY A paper by Bryan Togias Introduction The following paper is about the resumption of whaling by Norway with a focus on the American attitude towards whaling in general. Whaling is a very sensitive issue for many people, including myself. There are many people who feel that whales are highly intelligent mammals, akin to humanity in many ways. They cite the fact that whales mate for life, the size of the average whales brain, and the proof that whales communicate with one another ; all of these traits they share with us. The anti-whaling people feel that to kill whales for their meat or oil, would be like killing people for their meat or oil. The pro whaling ...

- Wolf Predation - 983 words
... ates that wolf population regulation is needed when a caribou herd population declines and becomes trapped in a predator pit, wherein predators are able to prevent caribou populations from increasing. The final model that attempts to describe the effects of predation on prey populations is the stable limit cycle hypothesis. This hypothesis proposes that vulnerability of prey to predation depends on past environmental conditions. According to this theory, individuals of a prey population born under unfavorable conditions are more vulnerable to predation throughout their adult lives than those born under favorable conditions. This model would produce time lags between the proliferation of ...
