When a vehicle is to be brought to a standstill or to slowdown, we have to convert kinetic energy into heat energy by the application of brakes. S= 0.5*M*v*v/f. total stopping distance is the sum of the perception-reaction distance and the braking distance. D_{total}=D_{p-r}+D_{braking}=v t_{p-r}+ \frac{v^2}{2 \mu g}. A common baseline value of t_{p-r}=1.5 s, \mu=0.7 is used in stopping distance charts.
From Wikipedia, the free encyclopedia. Hematology, also spelled haematology (from the Greek Î±á¼·Î¼Î±, haima blood and -Î»oÎ³Î¯Î±), is the branch of medicine concerned with the study, diagnosis, treatment, and prevention of diseases related to the blood.Hematology includes the study of etiology.n some institutions, hematologists also manage the hematology laboratory. Physicians who work in hematology laboratories, and most commonly manage them, are pathologists specialized in the diagnosis of hematological diseases, referred to as hematopathologists or haematopathologists.
Hematology is the study of blood in health and disease. It includes problems with the red blood cells, white blood cells, platelets, blood vessels, bone marrow, lymph nodes, spleen, and the proteins involved in bleeding and clotting (hemostasis and thrombosis).A hematologist is a medical doctor who applies this specialized knowledge to treat patients with blood conditions.Learn more about the types of diseases that hematologists study and treat, as well as the importance of having a hematologist as part of your health-care team.hen something is wrong with your blood, it can affect your total health. That is why it is important for you to know about some of the common blood disorders that may affect you.
