Average Metabolic Rate Difference of Goldfish in Dark vs. Ambient Light Introduction Metabolism is an interesting field of study to better understand what is happening inside of the body of different organisms that keep them alive. Goldfish (Carassius auratus) were used for this experiment since these small animals metabolism can be easily influenced by different variables. This is due to the fact that goldfish are poikilothermic whose internal temperature is influenced by their surroundings.…

there is an abnormality fluid collects in the neck tissue. Amniocentesis is a sample of the amniotic fluid surrounding the fetus is withdrawn through a needle inserted into the mothers ' uterus in a study by mayoclinic.org (pg2). Chorionic villus sampling (CVS) is a test when cells are taken from the placenta to be tested for DS. Although some of these diagnostic tests can diagnose Down syndrome in early stages of pregnancy some women chose to take an abortion if positive for DS. If the mother…

CHAPTER ONE INTRODUCTION 1.1 RESEARCH BACKGROUND The US Environmental Protection Agency (EPA) and the US Consumer Product (1995) (as cited in Preethi, 2005) sated that people spend approximately 90 percents of their time being indoors. Therefore, for many, due to more exposure of indoor air pollution than outdoor air pollution the risk to health may be greater. The building occupants may be exposed to the variety of contaminants whether in the form of gases and particles derived from office…

Fresh water lake ecosystems are very susceptible to invaders which degrade lake habitats and food webs. The Chinese mystery snail (Bellamya chinensis), referred to as Bellamya, is an understudied invasive species that is becoming more abundant in the fresh water lakes of North America and poses a threat to the ecological community of the Great Lakes. Understanding how Bellamya can effect lake ecology is critical to preventing the possible extinction of native snail species and the degradation of…

methodology involves a multistep approach consisting of a differential diagnosis, pattern recognition, and a final clinical component. The lengthy process must be completed before any treatment options are considered often resulting in over/under diagnosis, error, and lag-time. It would be of great benefit to develop a more effective system to heighten the potential advantages of early diagnosis. Current research involves the use of analytical techniques as diagnostic tools for a variety of…

accomplished in order to catch up with others assignments. Another factor that contributed to lack of communication from the nurse side with the dying patient is attributed by the doctors, because they place the nurse in a state of confusion due to errors they make in prescription and which often consume the nurse’s time in trying to clarify order and, adding more stress on nurses. Furthermore, another common stressor among nursing professionals who care for dying patients include; watching the…

The manufacturing of pharmaceutical tablets involves several main steps including blending, granulation, drying and milling. Each step is known as a unit operation and will be outlined below. The ingredients to make a pharmaceutical tablet will include the active pharmaceutical ingredients [API], and may require a bulking or binding agent which allows the tablet to be sufficiently large for consumption and provides sufficient surface properties of the particles within the mixture to facilitate…

4.1.4 Development of Feed Forward Control model in Simulink To implement feed forward control. Firstly, the transfer function of the linear DC Motor model has to be obtained. Actually in our case, the input of the plant is current so the transfer function of the mathematical model in ratio of angular velocity to current has to be obtained. It is given by: G(s)=Ω_1/I_a =R_A/K_M 1/(T_e s+1) where T_e=(J_meq R_A)/(K_m Cϕ) is electro-mechanical time constant. The feed forward control could be…

Brett Richards Mrs.McErlean Modern Literature 10/20/16 Media: Biased, Truthful, Impactful? Over the years the media has played a big part in a ton of things. Whether it was the news or an internet report the media has always had an effect on the situation. A question often asked is “Was the media biased, can we trust the media,and lastly what impact does the media really have on society and it’s people? The media and reporters are always faced with this question. People often have different…

In their research article, Graham and Linda Forrester, Lianna Jarecki, and Rebecca Flynn explored the effects of an anchoring event on a coral reef at Crab Cove in the British Virgin Islands. With an increase in tourism, recreational boat traffic has increased and some boaters don’t think about where their anchor is going when they throw it overboard. On July 7th, 2004, a 50 meter vessel named the Holo-Kai anchored overnight on the reef. The heavy chains and three anchors used to hold the…
