compounds that contain carbon – except CO‚ CO2‚ carbonates‚ and carbides • Even though organic compounds only contain a few elements‚ the unique ways carbon atoms can attach together to form molecules leads to millions of different organic compounds 4 1.1 Introduction to Hydrocarbon and Functional Groups What’s so Special About Carbon? Carbon atoms can do some unique things that other atoms cannot Carbon can bond to as many as four other atoms Bonds to carbon are very strong and

The researchers have also looked at carbon sequestration in pastures and are studying a mix of alfalfa — a.k.a. ‘the queen of forages’ — and sainfoin. “Currently we are looking at the different sainfoin germplasms that were used in the development of AC Mountainview‚ and some of these sainfoin

Carbon monoxide (CO)‚ nitrogen oxides (NOx)‚ sulfur dioxide (SO2)‚ ground level ozone and PM are common pollutants present in the atmosphere. The major contributor to air pollution discussed in the case study are Traffic related air pollution (TRAP). Motor vehicles release a mix of combustion and non-combustion emissions.9Fuel combustion produces carbon dioxide (CO2)‚ CO‚ NOx‚ PM‚ and volatile organic compounds (VOCs). A comprehensive

Infrared Remote Control Switch ABSTRACT Now a days‚ everyone wants to control their appliance wirelessly (i.e. remote control). Here is a simple tested and inexpensive remote control switch utilizing reading available components. The project is designed to operate electrical loads using a TV remote. The remote transmits coded infrared data which is then received by a sensor interfaced to the control unit. The system operates electrical loads depending on the data transmitted from the TV remote. Operating

Biofuels. Name: Institution: Course: Tutor: Date: A biofuel is made from a biological process known as carbon fixation. These biofuels are gotten from the conversion of biomass‚ solid biomass‚ liquid fuels as well as biogases. The biofuels are continued to be known because of the high prices of fossil fuels and also for the purposes of ensuring fuel security in various countries. (Caye‚ D. & Terry W.2008). The biofuels are produced from two distinct ways; that is through metabolic by-products

The Neolithic and Industrial Revolutions The two changes in the use of the earth’s resources that had the greatest effect on the world population were the Neolithic and the industrial revolutions. The Neolithic revolution (a.k.a. agricultural revolution) was a change in the way of life of our ancestors. It took place about 8000 years ago among various tribes in Asia and the Middle East. It included a transition from foraging and hunting to the domestication of animals (most probably starting

Peptidoglycan‚ also known as murein‚ is a polymer consisting of sugars and amino acids that forms a mesh-like layer outside the plasma membrane of bacteria (but not Archaea)‚ forming the cell wall. The sugar component consists of alternating residues of β-(1‚4) linked N-acetylglucosamine and N-acetylmuramic acid. Attached to the N-acetylmuramic acid is a peptide chain of three to five amino acids. The peptide chain can be cross-linked to the peptide chain of another strand forming the 3D mesh-like
