The Effects of Different Stress Levels on Bean Plants: Thigmotropism May 3‚ 2012 Abstract Bean plants were planted and rubbed a certain amount of times a day to apply stress. This was to see how plants might survive in a windy area or in an environment where they might be constantly touched or moved around. They were put under four different stress levels‚ and the plants were measured before the start of treatment to determine how they were being affected. The hypothesis was that those who

Killing Machines A drone is an unmanned aerial vehicle‚ an aircraft‚ without a human pilot on board. Its flight is controlled by a pilot on the ground or in another vehicle. These drones are used for remote sensing‚ commercial aerial surveillance‚ domestic policing‚ transport‚ scientific research‚ armed attacks‚ search and rescue‚ etc. The most controversial use‚ however‚ is armed attack. These drones are MQ-1 Predator UAV’s armed with Hellfire missiles. They were first used in 2001 from bases

EXPERIMENT 201: WORK‚ ENERGY AND POWER John Michael A. Ramos‚ Phy11l/A5 Abstract The essential conditions to be satisfied for work to be done are: Some force must act on the object. The point of application of force must move in the direction of force. W = F x s. SI unit of work is joule. Energy is the capacity to do work. The two types of mechanical energy are kinetic energy and potential energy. Kinetic energy is the energy possessed by an object by virtue of its motion. Potential energy is

Abstract The Tuskegee syphilis experiment was an infamous clinical study conducted between 1932-1972 in Macon Country‚ Alabama by the U.S Public Health Service. The purpose was to study the natural progression of untreated syphilis in rural African American men who thought they were receiving free health care from the U.S government; about four hundred African American men were denied. The doctors that were involved in this study had a shifted mindset; they were called “racist monsters”; “for

------------------------------------------------- ABSTRACT Separation processes by using the application of membrane have become highly demand in various industries. In this newly separation process ‚ the membrane function as a semi-permeable barrier and the separation process occur by the membrane controlling the rate of movement of various molecules between two liquid phases ‚ two gas phases or a mixture of a gas phase and liquid phase. In industries‚ many companies have high demand on both quality

The purpose of the experiment is to determine the effect of cross-linking has on the viscosity of the polymer solution. In the experiment‚ a hotplate was used to heat 50 mL of tap water in a 200 mL beaker to boiling. It took nearly two hours to fully dissolve 2 grams of PVA [poly(vinyl alcohol)] in the water by sprinkling minor amounts bit by bit. 10 drops of 0.1% methyl red indicator was added to PVA solution for the cross-linking part. 0.4 grams of borax was dissolved into 10 mL of hot water. 3

and Biotechnology‚ Mapua Institute of Technology ABSTRACT In this experiment‚ solubility class of various organic compounds are to be determined. The main objective of the experiment is to identify an unknown compound through the use of preliminary tests such as examination of physical state‚ color‚ odor‚ and ignition properties. Also‚ solubility tests were used to further examine an unknown compound’s solubility class. In this experiment‚ the apparatus used are micro test tubes and droppers

Experiment to Investigate Osmosis in Potatoes The aim of this experiment is to investigate the movement of water in and out of plant cells. The cells chosen for study will be taken from potato tubers. Firstly I will explain what osmosis is. Osmosis is the passage of water from a region of high water concentration through a semi permeable membrane to a region of low water concentration. This definition contains three important statements: a) It is the passage of water through a semi permeable membrane
