Throughout history, new ideas and inventions have been created from human intelligence effecting the way human life exist in today’s world. There have been different periods all around the world that have experienced some sort of lack development. Then there have been other times of great discovery and creation leaning towards something new and exciting. For a good amount of time, not too much development and creations were being brought forth upon. Part of the reason may be because of religion…

the bacteria under the microscope. The last agent you would add was safranin and this is too put back the color to the bacteria. I would then rinse and blot dry on bibulous paper. Then put oil on the slide then observed under the microscope-using eyepiece…

other objects as well, like glasses. One of the first inventors to experiment with lenses was Zacharias Jansen. Using his knowledge of the microscope,"Dutch optician Zacharias Jansen invents the compound microscope using two lenses, one for the eyepiece and one for the objective lens.” (Technology 104). Another inventor, Hans Lippershey in 1608, invents a refracting telescope, which uses two lenses. Galileo's invention of the telescope, helped others like Hans Lippershey create the refracting…

World War I or the Great War was a time period that caused many bloods and questioned morality. Each country was dedicated to make more powerful and effective weapons. Therefore, from 1914 to 1918, technology had been greatly advanced due to countries’ dedication and effort to create and improve blood shedding machines. Poison gases are one of the many weapons used during the Great War; this method of warfare creates and created controversies for ethical reasons. Even during the World War I when…

observe more than 50 times a day. Steps to clean the microscope. 1. Remove the objective lenses and clean inner and outer parts of them with a brush in order to remove the dust particles. 2. Repeat it to the other optical parts such as condenser and eyepiece. 3. Oil can be remove with a tissue paper or medical grade cotton wool. 4. At last optical surfaces should clean with 80% petroleum ether or 20% 2-propanol. 5. If there’s heavy contamination they can be removed by soap water. 6. Oils can be…

INTRODUCTION Tomato (Solanum lycopersicum L.) and Potato (Solanum tuberosum, L.) are the most economically important vegetable crops in Egypt and the most widely grown vegetables in the world. The disturbance of its production affects severely it's local and export impact, because it is considered a very important consumption crop with high nutritional value and a potential export crop for the Egyptian farmers. In Egypt about 20% of total area devoted for vegetable production is cultivated…

The objective of work was to optimize, formulate, evaluate and compare the transdermal gel containing vesicle based: Transfersomes and liposomes, containing Ketoconazole, an anti-fungal bioactive. Ketoconazole loaded Transfersomes were prepared using thin film hydration method with different concentration of surfactant (Span80, Tween80, and Sodium Deoxycholate) and soya lecithin and characterized for various parameters including Vesicles Size, Morphology, Entrapment Efficiency, Drug Loading…

To what extent did military technology develop during the course of World War One and how did this affect warfare? World War One, known as ‘The Great War,’ lasted from 1914-1918 and was a time of great technological growth in military technology. During the course of World War One, the inclusion of fighter aircraft, chemical weaponry and armoured tanks resulted in dramatic changes to military warfare.

Exercise 2: Observing Bacteria Cultures in Yogurt Firstly, we created an incubator using a Styrofoam cooler with a removable lid and a small hole in the top which was used for placing a 7 watt light bulb in order to maintain a Microbe growing temperature of 35-37° Celsius. We also monitored the temperature with the use of a thermometer. A teaspoon of yogurt was then placed into a clean plastic container with lid. The container was then placed in the Styrofoam incubator, which was not…
