Unlike the brain where a person can continue to be “alive” without any electrical activity‚ without a heartbeat‚ a person cannot live. The average person doesn’t ever think about how or why their hearts lub dub every minute of every day until they die. For someone whose heart doesn’t beat properly‚ the lub dub is a frequent worry. Brandon England is one of those people

Chemistry is the science of dealing with the compounds‚ elements‚ and molecular structure of matter. Essentially‚ chemistry is the science of examining substances and objects to find out what they’re made of and how the react to different conditions. All projects Accelerate Rusting To demonstrate how a chemical reaction from vinegar‚ water‚ and bleach can accelerate the rusting process of steel. Acids And Bases To determine which chemicals are acids and which are bases. Apple Mummy To

Clinical Chemistry When people consider their careers in the health care field‚ most of them would think about being a physician‚ a nurse or a surgeon. Individuals with interest in the health care field are not aware of clinical laboratory science. I am one of those individuals who don’t know much about clinical laboratory science before. After taking the class “Introduction to Clinical Laboratory Science”‚ I start to realize that clinical laboratory scientists are just like other health care members

The Inorganic Chemistry of Carbon Inorganic Carbon For more than 200 years‚ chemists have divided compounds into two categories. Those that were isolated from plants or animals were called organic‚ while those extracted from ores and minerals were inorganic. Organic chemistry is often defined as the chemistry of carbon. But this definition would include calcium carbonate (CaCO3) and graphite‚ which more closely resemble inorganic compounds. We will therefore define organic chemistry as the study

home. I decided to choose a different major which happened to be chemistry. I convinced myself that after all science is science. I decided that once I finished the chemistry major‚ I would support myself to study the laboratory science. I worked very hard in chemistry as I was aiming to graduate with honors. However‚ during the course of my study‚ I learned my things‚ which left me very surprised since I did not think that chemistry could contain so much information. In fact‚ it came to a point that

Processing Juveniles “Contact with a police officer often is a young person’s introduction to the juvenile justice system.” (Bolden-Barrett‚ n.d.) Whenever this occurs‚ there are potentially two outcomes‚ the police officer either sends a summons to a juvenile justice system pertaining to the offense/s of the juvenile or they choose to throw out the case. “Law enforcement’s role with youthful offenders‚ boys and girls under 18‚ is particularly challenging because federal law protects young people

Nuclear Chemistry Nuclear science is the study of sub-atomic particles and their function in various subjects. A nucleon is the collective name for the two components of the atomic nucleus: the neutron and the proton. Isotopes are any of the different forms of an element each having different mass numbers‚ which give the total number of nucleons. The major fundamentals of nuclear chemistry include radioactive decay‚ the nature of fission and fusion‚ and mass defect. The decomposition of the

and cellulose. Carbohydrates are high energy compounds because when they react with oxygen‚ they produce large amounts of energy. Plants make their own food by using the glucose they produces as an energy source for growth‚ reproduction‚ repairing damaged tissues... Animals cannot carry out photosynthesis‚ so they eat the plants to obtain food‚ hence‚ energy. For that reason the energy for life comes from the sun. 2.

4. Computer Hardware Image Gallery Graphics cards take data from the CPU and turn it into pictures. See more computer hardware pictures. The images you see on your monitor are made of tiny dots called pixels. At most common resolution settings‚ a screen displays over a million pixels‚ and the computer has to decide what to do with every one in order to create an image. To do this‚ it needs a translator -- something to take binary data from the CPU and turn it into a picture you can see. Unless
