I.History Trung nguyên is the most famous coffee brand in Vietnam. It was created in 1996 by Mr.Đặng Lê Nguyên Vũ. During student life in medical school of Tây Nguyên‚ Mr.Đặng had a question about coffee farmers’ life. Although the price of a cup of coffee wasn’t cheap‚ but why‚ farmers were still poor. This question encouraged him to find the answers. He and his company suffered from many accidents‚ but they kept on trying. Those experiences brought them a good background for opening more shops

The story seems to begin in Ethiopia‚ where the coffee berry grew wild. Goatherds there noted that goats which ate leaves and berries of the plant remained awake all night. The Arabs claim that they developed the plant during the reign of Mohammed (c675 AD). Believe that if you wish - we are going with the Ethiopian story. Consumed originally as a food‚ it would take on the character of a medicinal and eventually that of a social drink. The coffee tree grows to a height of 14 to 20 feet‚ producing

9/23/12 Lab Report #1 Meter Reading Summary The objective of this experiment was to learn how to read different meters like the D.C. volt meter and the D.C. amperes meter. In all meters each big line is a major division and each little line in between is a minor division‚ and if there is a line smaller than the minor division lines then that would be a sub minor division. Each meter has a low‚ medium‚ and high range. For example on the D.C. volt meter the ranges go from top to bottom 150‚ 15‚

Hoeung 1 Tiffany Hoeung Ms. Braceras Honors Earth Science 4 March 2015 How Does Slope Affect the Movement of a Glacier Purpose: The purpose of this lab was to find how slope would affect glacier’s movement‚ and whether the movement was at a constant rate or changed. Hypothesis: If the slope is more steep‚ then the glacier’s movements will be faster than a less steep slope. Materials: Flubber Glue Water Borax Long tray Timer Procedure: 1

Introduction The aims of the lab session was to familiarize with the principles‚ operation and application of a light spectrophotometer. This report discusses an experiment to study the relationship of absorbance and concentration‚ the interaction of electromagnetic radiant energy(ERE) and matter which is an important aspect of the Beer-Lambert ’s Law. This law states that the absorption of a compound is directly proportional to the concentration of that particular compound. This is because (a &

during the lab session Procedure Part A This lab was performed by the group members as they closed both low and high flow rotameters (Fig-2) and filled the tank with water. Then‚ the large rotameter was opened when the water in the tank had reached the internal baffle‚ so the flow from the tank was reduced by doing so. One member was in charge of adjusting the level of the water so it was always maintained over the baffle’s level during the lab (Fig-1). The first part of the lab was done

Lab Report Diffusion is - One of two kinds of passive transport‚ - Diffusion can transport ions from higher concentration to lower concentration region without any other forces. - A net movement of molecules in and out of cell membrane - Diffusion can be affected by the steepness of the concentration gradient. Lab question: Is the rate of diffusion influenced by the presence of second molecule? Prediction: the rate of diffusion is influenced by the presence of second molecule

that drinking coffee dehydrates us is a myth‚ scientists said last night. They said that while we may find it hard to believe‚ a few cups of coffee a day is as hydrating as water. The Birmingham University researchers called for health advice to be updated to reflect their findings. Sports scientist Sophie Killer said that the idea that coffee dehydrates stems from research done on samples of caffeine over 80 years ago. However‚ caffeine and the many other compounds in coffee interact with
