establishment or exploitation of such dominion for continuing material advantage.” So‚ in order to increase his ‘material advantage’ Leopold created the Force Publique‚ a group of men that uses terror as a source of influence on workers to make the rubber trade move faster and more efficiently. Leopold thought “the use of terror [was] the most cost efficient method of imposing rule and facilitating extraction.” Therefore‚ the Force Publique was generally made up of strangers to the area so the soldiers

Claisen adapter‚ which had a rubber septum in the opening directly over the flask. The condenser was attached to the other opening of the adapter. The top of the condenser was fitted with a rubber stopper equipped with a Y-tube. One of the arms of the Y-tube was connected to the water aspirator using rubber tubing with the other arm left open. Conducting the Reaction Aluminum chloride (AlCl3‚ 1.45 g) was quickly added to the round-bottom flask by removing the rubber septum‚ with caution as to

temperature of polymethylmethacrylate ( PMMA‚ Perspex) is measured using static and dynamic method while the glass transition temperature of rubber of different size is measured using only dynamic method. The glass transition temperature Tg of Perspex is found to be 90°C using the static method and 160°c using the dynamic method. On the other hand‚ the Tg of rubber is found to be -30°C. Introduction Perspex is a type of amorphous polymer and has the following repeat unit : If the PMMA is heated

The DoorShox car door protection solves the problem by eliminating vinyl magnets entirely. Instead the DoorShox car door protector uses 3 super powerful earth magnets that are strategically embedded into a foam body and covered with a silicone like rubber material that provides an (1) easy to clean surface (2) a soft impact absorbing material (3) and anti-slip surface. If car door dings have got you worried can a car door protector may be just what you need. The demand for car door protection has

and at many table tennis clubs‚ are required to have red and black rubber sheets on opposite sides. This rule was enacted to prevent players who use either two different advanced specialized rubber sheets with very different playing characteristics‚ or rubber sheets of the same type with one side altered‚ from having an advantage over their opponents. Before the two-color rule‚ a player could‚ by using two very different rubber sheets on opposite sides of the racket‚ gain an advantage by twirling

Commodity Chain Research Paper Introduction Centuries by centuries‚ life is becoming more and more convenient. For example‚ people don’t have to walk‚ they can take cars. In this way‚ vehicle is an important transportation in our lives. To make a car‚ chassis is the most necessary part because it consists of an internal framework that supports a man-made object in its construction and use. So‚ as a commodity‚ I think chassis is worth to discover. In addition‚ chassis is becoming more special and

Earwax ear Earwax is often soft and produced by glands in the outer part of the ear canal. Wax job is to keep the ear canal clean. The wax flows out slowly and take away debris. In some people’s wax tougher and sometimes the wax becomes extra tough when water comes in the ears. An early sign that you are about to get a Earwax may be that it knocks the lid when you have a shower‚ because the water caught up behind wax plug. Sometimes‚ the wax may be a reason that you hear worse. Avoid touching

between the rubber stoppers on your calculator and the aluminum dynamics cart track. The Experiment: 1. Find the coefficient of static friction by slowly raising the incline plane until the block just begins to slide. Note the angle. Repeat 3 times and average to accurately find the angle of repose. 2. Determine a method in which the coefficient of kinetic friction can be determined. 3. Perform your experiment to determine the coefficient of kinetic friction for the rubber stoppers
