ONE 1.0 INTRODUCTION Natural rubber is produced by over 2000 plants species and its main constituent is poly (cis-I‚4-isoprene).a highly unsaturated hydrocarbon. Since 1914 there have been efforts to investigate microbial rubber degradation: However‚ only recently have the first proteins involved in this process have been identified and characterized and have the corresponding genes cloned. Analysis of the degradation product of natural rubber and synthetic rubbers isolated from various bacterial

ELASTIC BAND PRACTICAL Introduction The elastic band‚ or rubber band as it is sometimes known‚ is an item that is generally taken for granted today. Because of their unique elasticity‚ they have many purposes. The main purpose is for storage but they can also be used for crafting. Elastic energy only lasts for a short period of time but is comparatively strong. Aim To investigate the amount that a rubber band is stretched when consistently increasing amounts of weights are placed Hypothesis

Physics (Thorpe Park Trip) Report: On Monday 8th October our physics class went on a physics trip to Thorpe Park to look at the different ways in which a roller coast works. This report will be looking at the G forces acting on rides‚ the launching systems and breaking systems. The particular rollercoaster which I have picked to look into more detail in is “Stealth” which is located in Thorpe Park. Stealth: Stealth was originally designed by Werner Stengel. Stealth reaches a height of 205 feet

The Bubble Bath Rubber Ducky Experience When I found out that there was a paper due on having to take a bubble bath with a rubber duck‚ I was thinking‚ “why? How very odd but okay‚ I guess I’ll do it.” Then I found out that we had to bring the rubber duck to school and I was like‚ “really? Uhm... Okay then. I’ll have to pass by wal-mart on my way home then.” So‚ I eventually got around to doing the bubble bath. I put way my cell phone‚ my laptop & told everyone not to bother me unless they

1.Discuss the structure of the plasma membrane and explain the process of active and passive transport through the membrane. 2. Explain your observations in detail in terms of concentration gradient‚ diffusion‚ osmosis‚ osmotic pressure‚ passive transport‚ and active transport. Explain what happened to the blood cells at the various levels of concentration. Be sure to refer to the solutions as being hypotonic‚ hypertonic and isotonic. The plasma membranes are made up of proteins that form

Newton’s second law of physics dictates that acceleration is produced when a force acts on a mass. The greater the mass of the object‚ the greater the force needed to put the object in an accelerated motion. This relationship can be viewed in the formula: Force = mass (acceleration) The key to keeping the mousetrap car accelerating is to keep the forces acting upon it unbalanced. The force of the mousetrap car has to be larger than the force of friction working against the car. Because the force provided

What is Physics? Physics is a field of science that shows the interaction between matter and energy. It shows physical processes that help us understand better how our universe behaves. Physics also use scientific method that formulates and tests hypothesis which are based on observations and comprehensions. What are the different fields under Physics?

Rubber Boom Slavery Dating back hundreds of years the indigenous people of South and Central America had discovered the many uses of rubber‚ taken from what is known as a "Hevea brasiliensis" or more commonly‚ a rubber tree. When the latex is extracted from the tree it is hardened and formed into rubber which natives would use for numerous tasks such as making shoes‚ handles for tools‚ and even rubber balls for sports (Dean 23). Due to its useful yet uncanny features it created an immediate
