Although water-assisted injection moulding is a relatively new and advanced technique to produce hollow parts, several problems which reduce the product quality can occur. Namely, water inclusions in the wall, severe fingering and double wall defects reduce the product part stiffness. This study investigated the …
Lead is a naturally occurring element present in the earth’s crust. It is one of the most harmful environmental pollutants. It has become difficult to control because of its wide usage. Over the years it is being used in gasoline, house paint and plumbing fixtures. …

Concrete fix can be defined as the act of regenerating, reconstructing, or replacing of any concrete or concrete surfaces after initial arrangement ( Smoak et al, 2002 ) . In general, the demand for concrete fix can originate from different causes which may change from …
Generally, atmosphere layers are hot if they contain gases that absorb some of the light that penetrates to that depth. Transparent layers are cool. The temperature of a layer is generally found by the balance between absorption of solar radiation (heating) and the emission of …
A redox titration, involving an Iodometric method, has been used to do the analysis. L-Ascorbic acid was first isolated as a pure substance by Albert Agent-Gyorgi and Charles King 1928, an anti-oxidant and free radical scavenger, is found ubiquitously in fruit and vegetables such as …
A membrane is a type of selective barrier that is used to separate or concentrate the feed stream as it passes through the membrane, which selectively allows some constituents to pass as others are retained on the surface of the membrane. The constituents that are …
Conjugation
The word "conjugation" is derived from a Latin word that means "to link together". In organic chemistry terms, it is used to describe the situation that occurs when π systems (e.g. double bonds) are "linked together". An "isolated" π (pi) system exists only between a single pair of adjacent atoms (e.g. C=C)
Kinetic energy
Kinetic energy is the energy associated with objects in motion. Potential energy is the type of energy associated with an object's potential to do work. Chemical energy is the type of energy released from the breakdown of chemical bonds and can be harnessed for metabolic processes.
Physics
Chemical physics is concerned with the application of the concepts and theories of physics to the analysis of chemical systems and their physical behaviour. While also at the interface between physics and chemistry, it is distinct from physical chemistry.
