Electrochemical cells (Contd...)
The electrodes used in the cells discussed so far, deteriorate with the passage of current and cannot offer a constant emf indefinitely. However, there was a few cells called standard cells, which can maintain a fairly constant emf over very long perio..
Solid State cells
The cells discussed above use a liquid electrolyte, one cathode and an anode. Some of the major disadvantages of these cells are leakage on long term storage, corrosion due to the use of liquid acidic/alkaline solution, short life, low weightage per kg mass of the ..
April 29, 2009 At least 24 million American adults and children have diabetes and struggle with its many complications, including heart disease, amputation, and blindness. Scientists believe that stem cell research holds great promise in the quest for a cure for type 1 diabetes and provides a powerful tool for controlling type 2 diabetes. In a panel discussion, leading stem cell scientists and patient advocates came together on April 29, 2009 to discuss the latest developments in stem cell ...
Frontiers of Biomedical Engineering (BENG 100) Professor Saltzman continues his discussion of cell communication in the body, extending the description to the nervous and immune system. Professor Saltzman describes the mode of signal transmission in neurons: action potential in the axon, and neurotransmitter release at the synaptic cleft. He also introduces elements of the innate and adaptive immune system. The adaptive immune system is presented as a host/foreign antigen recognition system ...
Question : I am doing a research project for science class. Us students are put into groups of four and each person has a specific job. Im suppose to develop a list of question that are to be used in class for discussion.
But im having difficulty coming up with different questions that could be asked. All ive got is the basic: Are you for or against stem cell research?
Answer : Catholics believe that life is a sacred gift from God and needs to be treated with all human dignity from the moment of conception to the point of natural death. For this reason, the destruction of human embryos to harvest embryonic stem cells is immoral. The end never justifies the means A moral good can never come from a moral evil Here are just a few of the common myths about Stem Cell Research: Myth: Stem cells can only come from embryos. Truth: Stem cells can be taken from: Umbilical cords The placenta Amniotic fluid Adult tissues and organs including bone marrow, fat from liposuction, regions of the nose and even dead bodies up to 20 hours after death Myth: The Catholic Church is against stem cell research. Truth: The Catholic Church approves three of the four types of stem cell research: Against Embryonic stem cells For Embryonic germ cells (from miscarriages) For Umbilical cord stem cells For Adult stem cell....

Question : What are some good discussion questions to ask a high school class on the following topics:
1. Abortion
2. Stem Cell Research
3. Euthanasia
4. Capital Punishment
Answer : OK for high schoolers (or anyone for that matter) 1) Abortion What is more important the right to life of the fetus or the right to liberty of the woman? Where is the line between to 2 fundemental rights? Whose decision should it be: society's or the woman's? Is it ethical for abortion to be used as birth control? 2) Stem Cell What sources are ok to take stem cells from? What precautions could be taken to help ensure no abuse of system? 3) Euthanasia Whose decision is it? What if the person has dementia? What protections would be needed to prevent abuse such as family euthanizing an elderly person whose medical costs are to high in a bad economy? Are there certain requirements such as age, sickness, etc or is it open to anyone for any reason? 4) Capital Punishment Should society be required to pay for and support the worst cases for rest of their lives when productive members of society have been killed? Is it right for a govt to say you cannot ki.... More from Yahoo Answers
