What Are Stem Cell?
STEM CELL WHAT ARE STEM CELL? All of us start from a single cell formed at conception, when a sperm cell joins with an egg. This cell then starts dividing and forms a ball of cells. About four days after conception, this ball of cells is smaller than a pinpoint. This process, called differentiation, allows some cells to become liver cells and other cells to become nerve cells or skin cells and so on. This

Car Engine, Brief Fuel System Explanation
THE FUEL SYSTEM The fuel system pumps fuel from the tank and mixes it with air so that the proper air/fuel mixture can flow into the cylinders (because to make the little explosion to work it needs oxygen) then it give out a little spark. Fuel is delivered in three common ways: carburetion, port fuel injection and direct fuel injection. • In carburetion, a mechanism called a carburetor mixes fuel into air as the air

Sickle Cell Disease
Sickle Cell Disease is a hereditary blood disorder that affects the oxygen-carrying part of blood, the red blood cell. In other words, it is visible by diseased red blood cells that have a sickle shape. Red blood cells have proteins called hemoglobin. Hemoglobin transports oxygen from your lungs to every part of your body. When a normal red blood cell (with normal hemoglobin) releases its oxygen, it maintains its disc shape. However, when a diseased

Sickle Cell Anemia
Sickle Cell anemia is a blood disease that is inherited by the parents and lasts forever. The ones that have this disease inherit two genes from each parent that are abnormal which are the sickle cell genes. These genes inform the body to make abnormal hemoglobin which causes the red blood cells to be deformed. A single change in the amino acid building blocks of hemoglobin causes the sickle cell mutation. The changes in

Steam Cell
Stem Cell Stem cell research has been a major controversy for the last few years. But what exactly is a stem cell? Stem cells have the remarkable potential to develop into many different cell types in the body. Serving as a sort of repair system for the body, they can “theoretically” divide without limit to replenish other cells as long as the person is alive. When a stem cell divides, each new cell has the

Sickle Cell Anemia
Sickle Cell Anemia Jenkins 1 Abstract Sickle Cell Anemia is a hereditary disease that changes the smallest and most important components of the body. A gene causes the bone marrow in the body to make sickled shapes, when this happens; it causes the red blood cell to die faster. This is what causes Hemolytic Anemia. Older children and adults with sickle cell disease may experience a few complications, or have a pattern of ongoing

Developing Female and Male Germ Cells in Fetilisation
The female and male germ cells are reproductive cells that fuse with one another during fertilization (Burfoot, 1999). Each possesses unique characteristics and molecular structure during the pre-fertilization phase of development and post-fertilization. These characteristics are influenced by the production of various hormones in the male and female body. Fertilization occurs when the materials from two gametes come together to form an embryo. The female gamete is often referred to as the egg or female

Stem Cells and Therapeutic Cloning
Stem Cells and Therapeutic Cloning Embryonic stem cells were grown in a laboratory successfully in 1998. At that time researchers were able to have the stem cells begin copying themselves without becoming anything further (Easterbrook, 2000). This was an exciting time for researchers to begin discovering this new technology. The therapeutic cloning process begins when the nucleus is removed from a human egg and replaced with the nucleus of a body cell from the person

The Impact of Catalytic Materials on Fuel Reformulation
The impact of catalytic materials on fuel reformulation Stefano Rossini Snamprogetti, S. Donato Milanese, Italy Abstract Fuel reformulation has been seeded by the growing consciousness of the potential damages mankind was causing to the ecosystem and to itself. Fuel reformulation means that fuels are defined on a chemical composition base with additional engine-technology related standards rather than on pure performance bases. These standards, which are getting more and more stringent, can be met by different
