(FROM WIKIPIDEA PAGE 1&2) The Aeta (Ayta‚ pronounced eye-tə)‚ or Agta‚ are an indigenous people who live in scattered‚ isolated mountainous parts of Luzon‚ Philippines. They are considered to be Negritos‚ who are dark to very dark brown-skinned and tend to have features such as a small stature‚ small frame‚ curly to kinky afro-like textured hair with a higher frequency of naturally lighter hair color (blondism) relative to the general population‚ small nose‚ and dark brown eyes.

Abstracts Innovate a machine which is easy to use and that cannot tolerate with their accuracy‚ without affecting the prize of the machine. All over the world the resources of energy are reduced for that we can find new sources of energy. For that machine is both manually and power operated. In India‚ there is many industries which are engaged in production of manually pipe bending machine. Presently the pipe bending machine is power and manually both operated. But‚ the manually operated

onto the balance. The result is rounded to two decimal places. The graduated cylinder is used for measuring volume of a liquid or water displaced by a solid. The students look at lines‚ at eye level‚ drawn onto the side of the cylinder to measure the liquid level‚ significant figures depends on how accurate the marks go. Pipettes suck up or expel liquids. Students use the pipette to move liquids to a graduated cylinder by squeezing the top of the pipette to cause suction. Procedures: Students

An Investigation Into The Effect Of PH On The Activity Of Potato Tissue Catalase Aim The aim of my investigation is to see how pH affects the activity of potato tissue catalase‚ during the decomposition of hydrogen peroxide to produce water and oxygen. Catalase + 2H2O2 Catalase + 2H2O +O2 Catalase + Hydrogen Peroxide Catalase + Water + Oxygen Independent Variable The independent variable in this investigation is pH. Each individual enzyme has it’s own pH characteristic

INTRODUCTION CRDi stands for Common Rail Direct Injection meaning‚ direct injection of the fuel into the cylinders of a diesel engine via a single‚ common line‚ called the common rail which is connected to all the fuel injectors. Whereas ordinary diesel direct fuel-injection systems have to build up pressure anew for each and every injection cycle‚ the new common rail (line) engines maintain constant pressure regardless of the injection sequence. This pressure
