Microorganisms
Microorganisms are referred as predominant source of commercial enzyme (Wiwapat et al., 2002, Kvesitadze, Kvesitadze 1990, Kutateladze et al., 2009). Due to diverse spectrum of applications enzyme production now became a multi-billion dollar business (Bhat, 2000). The market of the technical enzymes showed great diversity both in terms of the applications as well as the consumption. It has been evaluated that global sale of enzymes was $1.7–2 billion in 2005 which is expected to grow

Microscale Preparation of Methyl Orange
Microscale Preparation of Methyl Orange Conner Page | Background and significance The dyeing of fabric has been done for thousands of years but, it wasn’t until 1876 that Otto Witt made the first attempt to interpret color of dyes in terms of chemical structures. Witt proposed that dyes consist of conjugated P-bonded systems, chromophores, and salt forming groups, auxochromes, which are polar substituents that would modify color. A chromophore is an unsaturated, electron withdrawing group

Mind and Brain
The brain is the control center for many actions that occur in the body. Its ability to conduct complex processes is due to the interconnecting of its 100 billion neurons. Neurons are able to communicate with each other through the neurotransmitters that are released at specialized junctions called synapses. These synapses are found in two locations where the pre-synaptic terminal is found at the tip of an axon and the post-synaptic terminal is on the

Misconcepualiztion of Hormone
MISCONCEPUALIZATION OF HORMONE RESEARCH Hormone research has been greatly influenced by cultural assumptions about the dimorphism of gender. Much of the scientific data produced and taken as ‘knowledge’ reaffirms social ideologies already thought to be true and uses this data to essentially prove these ideas. In the case of hormone research, ideas about the innate differences between males and females were imposed upon the scientific methodologies and the conclusions made. The misconception of estrogen

Mitosis and Meiosid
As viewed from a human perspective, nature has done some ingenious engineering to overcome some of the obstacles it has faced. Take the evolution of sex, for instance. To make the move from asexual to sexual reproduction, nature took a system by which parent cells reproduced simply by dividing (asexual reproduction) and altered it to allow two parent cells to combine to create offspring (sexual reproduction). It met this challenge by devising (again, speaking from

Mixer and Nozzle Process Description
Mixer The hot air that is forced out of the combustor and through the turbine continues to exit the engine at the rearward. Before exiting however, this air must be mixed with the cooler bypass air that did not go through the compressor and combustor. These two airstreams are mixed in order to quiet the engine. To understand how air can create noise, first consider the way water splashes and makes noise when a wave

Emphysema Emphysema Jennifer Davis Modesto Junior College ________________ Abstract Emphysema has long been lacking a clinical definition but instead is often defined in pathological terms. As a disease affecting the airspaces or parenchymal, and not the bronchi. The American Thoracic Society states that emphysema exists when “there is an anatomical alteration of the lung characterized by an abnormal enlargement of the airspaces distal to the non-respiratory bronchioles, accompanied by destructive changes of the alveolar walls”³.

Molar Volume of a Gas
Introduction Molar volume is the name given to the volume that one mole of any gas occupies at standard temperature and pressure. In chemistry, many of the materials worked with are gases. It is often easier to measure the volume of a sample of gas, rather than determine its mass. The main purpose of this lab is to determine the molar volume of hydrogen gas experimentally in order to compare it to the theoretical molar
