all transport systems. Burgeoning travel demand far exceeds the limited supply of transport infrastructure and services. Public transport‚ in particular‚ has been completely overwhelmed. Most bus and train services are overcrowded‚ undependable‚ slow‚ inconvenient‚ uncoordinated and dangerous. Moreover‚ the public ownership and operation of most public transport services has greatly reduced productivity and inflated costs. India’s cities desperately need improved and expanded public transport service

chemical reactions organisms‚ allowing cells to break or build things instantly. The structure of an enzyme is essential to its function. Enzymes are proteins‚ made up of 100-1000 amino acids bonded together in chains. These chains are folded/coiled into a unique 3-D structure that allows them to bind to a reactant‚ called a substrate at an active site. Enzymes are flexible‚ and therefore can change it’s shape to better accommodate its substrate; this is the induced fit model (D. Fraser‚ 50). When

Narcotics Anonymous (NA) meeting Reaction Paper Denisha Hightower Morgan State University Dr. Anthony Estreet 4/15/15 The Narcotics Anonymous meeting which I attended was named 7 Days of NA which was located on 1212 North Wolfe Street at an organization called Dee’s Place. Just as the Alcoholic Anonymous meeting previously attended‚ the location appeared to be in a covert and quiet place to hold a support group. We entered through the rear entrance‚ which seemed to be staged that way to

Our country‚Malaysia is a well develop country. That goes for public transport too. It also well develop. There always have some issue that should we having a free public transport.This issue already exist for some time.Resident of Malaysia always question about this issue.Some of them hoping that can get a free public transport but some reject this idea.As for me‚I totally agree about the free public transport.There are some benefits that we can get. First of all‚the benefits is save money.For

DENATURATION OF PROTEINS Abstract The experiment aimed to use the concept of viscosity to study the effects of different denaturants on 1% albumin extract. An Ostwald viscometer was used to measure the flow time of 5 mL of the blank and native protein. These were then denatured by adding 1 mL of denaturant and had their flow time measured. The flow time from the blank to denatured protein is increasing. The specific viscosity and reduced viscosity

Relationships of Proteins Proteins are a group of organic compounds whose molecules consist of carbon‚ hydrogen‚ oxygen‚ nitrogen and sometimes sulfur atoms. They are condensation polymers of amino acids that are joined by strong peptide bonds. There are 20 different types of amino acids available‚ and the different combinations of these amino acids give it different structures and specific functions to it. Below in this essay‚ will illustrate the how different structure of a protein is related to

The main factors that affect distribution of population are natural resources‚ climatic conditions‚ soils‚ cultural factors‚ age of human settlement‚ industrial development and means of transport and communication. The factors affecting distribution of population are described below one by one in a nutshell manner. (i) Natural Resources: The regions having rich wealth of natural resources like coal‚ water‚ minerals and forest wealth favour the growth of population. These resources help in the

Proteins are polymeric chains that are built from monomers called amino acids. All structural and functional properties of proteins derive from the chemical properties of the polypeptide chain. There are four levels of protein structural organization: primary‚ secondary‚ tertiary‚ and quaternary. Primary structure is defined as the linear sequence of amino acids in a polypeptide chain. The secondary structure refers to certain regular geometric figures of the chain. Tertiary structure results from

Introduction The airline industry has been plagued by factors such as overcapacity‚ commoditization of offerings or competition‚ high level of rivalry‚ entry of low cost carriers. other factors include several macro-level socio economic troubles‚ SARS crisis‚ 9/11 attacks‚ bird flu‚ Asian Tsunami and other terrorism concerns‚ due to this there has been a big impact on airline profit. As market condition is continuously changing‚ it is difficult to predict the future of the airline industry. the

Identifying sites of protein synthesis in Chlamydomonas using erythromycin and cyclohexamide as protein synthesis inhibitors. October 16‚ 2009 Introduction: In living cells‚ prokaryotic or eukaryotic‚ the synthesis (construction) of proteins is accomplished by similar machinery. Amino acids‚ ribosomes‚ messenger RNA (mRNA)‚ and transfer RNA (tRNA)‚ are all necessary for the building of functional proteins in a cell. Ribosomes are the site of protein synthesis in a cell‚ and there are two
