adulteration of food. It has engulfed the developing and the underdeveloped countries for the past decade. There are 400 million children in India. Malnutrition‚ diseases like polio and even prejudice continue to threaten their healthy existence. When we see such young children and adults suffering from various diseases due to the adulteration of food‚ we realize that it become a big problem now. Food adulteration can be defined as the intentional debasing of the quality of food offered for sale

Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source

Column and Thin Layer Chromatography: The Separation of Spinach Pigment Abstract Spinach extract was separated into fractions containing compounds of similar polarity by column chromatography. Based on solid-liquid phase partitioning‚ this separation technique exploited the different polarity of the compounds in the spinach extract. Three fractions with different colors were obtained. The extract and its fractions were analyzed using thin layer chromatography (TLC). The TLC results showed that

Healthy Food vs Junk Food Diet is almost everything according to nutritionists. The importance of consuming a healthy diet is immensely beneficial for a good and enjoyable lifestyle. As many religions and persisting cultures refer‚ the food that we eat should be in the desired quality in terms of nutrition as well as taste. However‚ the world today is facing a serious problem regarding junk food or unhealthy food. Many health-related problems have a common origin‚ that is junk food. Therefore‚

Fresh Food and Canned Food Eating is most important activity in our life. Some people eat 2 times‚ 4 times‚ or some people in poor countries eat only 1 time a day. We live in a world where the variety of food is immense‚ and we are responsible for what we eat. We decide what we are about to eat and how it will affect our bodies. The three main differences between fresh food and canned food are flavor‚ health benefits‚ and cost. The most notable difference between these two kinds of foods is their

Re = Reynolds number V = Fluid velocity (m/s) d = Pipe diameter (0.012m) v = Kinematic viscosity (0.893 x 10-6m2/s) Laminar Flow‚ Re < 2000 Laminar flow denotes a steady condition where all stream lines follow parallel paths. Under this condition‚ the dye will remain
