The History of Caterpillar Engines The start of Caterpillar engines actually begins before Caterpillar was even a company. The history began back in the late1800’s when Daniel Best and Benjamin Holt were experimenting with various forms of steam tractors used for farming. The two competed with each other to gain the lead in the farm equipment industry. Throughout the late 1800’s and early 1900’s Holt and Best continued to build both steam and gas tractors. In 1908 Best sold his company to Holt

Japan and Western Europe are two countries on opposite sides of the earth‚ yet both had a time period known as the feudal period. Japan’s feudal age (12th century to the = 15th century) is comparable in many ways to Europe’s feudal age (9th century through the 15th century‚ also known as the Middle Ages). Three specific areas that share differences and similarities between these two ages of feudalism are in politics‚ culture‚ and social structure. An area in which the West and Japan are as different

The Impact of Western media on African Cultures By Levis Kamau Introduction Pop music has become very much popular and widespread among the young people in Nairobi City. It is usually characterised by western behaviours and ways of doings of the west (developed countries) particularly the United States and Jamaica. It is very common to hear young people talking about the pop singers. You will always hear “I like that dance in the song….” “I wish I had such a cloak”

ABSTRACT Camless internal combustion engines offer major improvements over traditional engines in terms of efficiency‚ maximum torque and power‚ pollutant emissions. Electromechanical valve actuators are very promising in this context‚ but still present significant control problems. Low valve seating velocity‚ small transition time for valve opening and closing‚ unavailability of position sensor are the main objectives to be considered in the design of the valve control system. Actuator physical

A jet engine‚ like a rocket engine‚ is a reaction engine. It works by throwing mass in one direction and taking advantage of the reaction in the opposite direction. In the case of a jet engine‚ the engine burns fuel (like kerosene) with air from the atmosphere. The burning fuel heats and expands the air‚ and this hot air shoots out of the exhaust-end of the engine to create thrust. Most modern jet engines use a turbine to improve the efficiency of the engine and allow the engine to work at low speeds

After the fall of the Roman Empire (5th – 6th century)‚ bathing was not common at all especially in Western Europe‚ Japan and Southwest Asia; Simply because of the decline in wealth and in technology. Taking a bath required a lot of time and effort. You had to get buckets of water and wait for the water to get hot enough so you could take a shower‚ then you had to make sure you had enough soap to bath with. After the 5th and 6th century bathing was considered temporary and not important. There are

roots of plants. In this experiment‚ the essential oil eugenol was isolated from ground cloves using steam distillation techniques. Eugenol had a high boiling point‚ but it was isolated at a lower temperature by performing a co-distillation with water‚ a process known as steam distillation. This technique allowed the desired material to be distilled at a lower temperature than 100℃. The point of the steam distillation was to use an azeotrope to isolate the organic compound from a solid. The azeotrope
