AS Level Physics: Terms & Definitions:- Measurement Random errors are errors of measurements that result in a scatter of readings about a mean value. Systematic errors are errors of measurement which occur according to some fixed patterns such that they consistently give out an over-estimation or under-estimation of the true value. Accuracy is a measure of how close the results of an experiment agree with the true value. Precision is a measure of how close the results of an experiment

Metallobiomolecules METALLOBIOMOLECULES CONTENTS 1. Introduction Metallobiomolecules 2. Classification Metallobiomolecules 2.1. Transport and of to Storage Proteins 2.2. Oxygen binding Today scientists try to explore the chemistry basis behind the biological processes. As a result of this‚ new areas have evolved such as bioinorganic chemistry and bioorganic chemistry. In this section we will talk about an important concept in bioinorganic chemistry called “Metallobiomolecules”. Metallobiomolecules

Health care code requirements Introduction: The health maintenance and enhancement‚ the safety and the comfort of people in health care facilities are seriously affected if specific building requirements are not met. Hospitals are the most complex of building types. Each hospital is comprised of a wide range of services and functional units. Functional organization criteria classify health care facility environments as follows: nursing units‚ operating theatres‚ diagnostic facilities (radiology

melt the ice on the roads. KCl is important for plant fertilizers since potassium helps plant growth. The metal halides form white ionic crystalline solids. They are all soluble in water except LiF because of a high lattice enthalpy due to the electrostatic attraction between Li+ and F- ions. All halogens are quite reactive‚ and in the natural world they always occur combined with other elements. Fluorine reacts so readily with almost any substance it contacts that chemists were not successful

that he calculated as having a very large value for the charge-to-mass ratio. Later he estimated the value of the charge itself. In 1904 Thomson suggested a model of the atom as a sphere of positive matter in which electrons are positioned by electrostatic forces. His efforts to estimate the number of electrons in an atom from measurements of the scattering of light‚ X‚ beta‚ and gamma rays initiated the research trajectory along which his student Ernest Rutherford moved. Thomson’s last important

Pollution is the introduction of contaminants into a natural environment that causes instability‚ disorder‚ harm or discomfort to the ecosystem i.e. physical systems or living organisms. Pollution can take the form of chemical substances or energy‚ such as noise‚ heat‚ or light. Pollutants‚ the elements of pollution‚ can be foreign substances or energies‚ or naturally occurring; when naturally occurring‚ they are considered contaminants when they exceed natural levels. Pollution is often classed
