with the standards. The purpose of this experiment is to analyse the hardenability of the three materials such as EN-3 (1015)‚ EN-8 (1040) and EN-24 (4340). 1.2 Objectives The test has following objectives‚ to check the hardenability of different metals‚ the effect of carbon on the material’s hardenability and the comparison of the link between the microstructure and the cooling rate [1]. 1.3 Additional Comments The results are plotted as functions of distance from the quenched end‚ yielding hardenability

GOFFMAN‚ SCHEFF AND SCASZ ARGUE THAT MENTAL ILLNESS IS A SOCIAL CONSTRCUTION. Mental illness is a general term referring to psychological‚ emotional‚ or behavioural disorders as well to the view that these disorders are diseases of the mind. Because it’s more to do with the psychological aspect‚ methods of treatment are different from a physical disability. A physical disability may involve treatment like acupuncture and traditional medicine whilst a mental illness (disability) treatment involves

One example is the transition from hospital care to home. Primary care providers should be mindful of how difficult‚ frightening‚ and frustrating this transition can be. One thing providers can try to do to help is improve communication between the various providers and systems and between the providers/systems and the family. They can also consider systems change like changes to the pay structures and transition care ("step down") after hospitalization where the

calculated and illustrated with respect to time. This occurred for varying temperatures. From the internal energy of the system per time step‚ the heat capacity was determined. Heat capacity was then plotted against temperature in order to view phase transitions. The results show almost independence of heat capacity-temperature curves with respect to the number of particles. That is‚ for all numbers of particles in said range the heat capacity rises with respect to temperature and then plateaus at temperatures

have been precipitated by microbes which include carbonates‚ sulphates‚ silicates etc [1]. Amongst all these‚ carbonates are the most common minerals formed. Carbonate precipitation has been applied in several fields ranging from removal of heavy metals and radio nucleotides‚ waste water treatment‚ biodegradation of pollutants‚ CO2 sequestration and filler in rubber and plastics and greatly in remediation and restoration

element in the periodic table‚ it is in period 4‚ group 16 which is also called the chalcogen group. The term chalcogen stands for “sulfur”‚ therefore all elements in family 16 are similar to the element sulfur. All the elements in family 16 are non-metals and all of these elements in chalcogen family have six electrons in the outermost shell so they all have the similar properties. Give a description of the physical characteristics and chemical properties of the element. Physical characteristics:

optical microscope and scanning electron microscope. Introduction This paper contains some important experiment results concerning metals properties. The main aim of the laboratory experiment was to examine and to compare the microstructure and hardness of different carbon content metals‚ starting from 0.2%C‚ 0.4%C‚ 1.0C% content metals with different heat treatment and cooling mechanism. The experiment was started from the preparation of the samples. At the first step the samples

------------------------------------------------- State of matter From Wikipedia‚ the free encyclopedia States of matter in physics are the distinct forms that different phases of matter take on. Four states of matter are observable in everyday life: solid‚ liquid‚ gas‚ and plasma. Further states are possible but do not naturally occur in our environment: Bose–Einstein condensates‚ neutron stars. Other states‚ such as quark-gluon plasmas‚ are believed to be possible.
