Control of Postharvest Anthracnose Using Chitosan and Lemongrass Oil Abstract Anthracnose is a postharvest disease of mango caused by the fungus Colletotrichum gleoesporiodes that results in major economic challenges during transportation and storage. It limits mango production in our country especially where high humidity prevails during the cropping season. Symptoms of this postharvest disease are black spots‚ starting from the stem‚ then proceeding to infect the mango fruit itself. For the control

most accurate forecast possible so they can plan for the demands. There are forecasting tools that assist with making calculations to receive the best outcome by your company’s needs. The tools are moving average‚ weighted moving average and exponential smoothing. The moving average takes the total of actual demand for previous months then divides by the number of months added. The number of months that is used can be predefined such as using the previous three months. This is the simplest

eightweek period have been 14‚ 9‚ 30‚ 22‚ 34‚ 12‚ 19‚ 23. a. Suppose that three-week moving averages are used to forecast sales. Determine the one-step-ahead forecasts for weeks 4 through 8. b. Suppose that exponential smoothing is used with a smoothing constant of α = 0.15. Find the exponential smoothing forecasts for weeks 4 through 8. c. Based on the MAD‚ which method did better? Solution: a. Week 4 5 6 7 8 b. and c. You may start ES forecast from week 1 or start ES forecast from week 4 using MA(3)

Chapter 6 Microbial Growth 1 Growth • increase in cellular constituents that may result in: – increase in cell number • e.g.‚ when microorganisms reproduce by budding or binary fission – increase in cell size • e.g.‚ coenocytic microorganisms have nuclear divisions that are not accompanied by cell divisions • microbiologists usually study population growth rather than growth of individual cells 2 The Growth Curve • observed when microorganisms are cultivated in batch

modernize with her changing community. The theme of decay is shown throughout the entirety of the story. Faulkner sets the story through a twenty-year span before and after the Civil War; his use of imagery helps the reader visualize the decay of the traditional homes as the rest of the town modernizes. Faulkner then shows the decay of Miss Emily‚ a well-known tradition throughout the town of Jefferson. The Grierson family home is a physical symbol of decay throughout the story. Faulkner uses the southern

2012. The effects of this population increase are evident in the increasing poverty‚ unemployment‚ air and water pollution‚ shortage of food‚ health resources and educational resources. With India as an example we will discuss Malthus‚ the population growth theory and see if Malthus theory was maybe mistaken in the past but has some valid aspects today. Thomas Malthus was an English priest and economist who lived during the late 18th Century. He is famous for his theories about population and its increase

Radioactive Decay‚ Nuclear Fission and Nuclear Fusion When elements undergo radioactive decay the atoms of one element are changed into the atoms of another element when an alpha or beta particle is emitted from an unstable nucleus. When a nucleus disintegrates and emits an alpha particle it is alpha decay‚ the alpha particle emitted contains two protons and two neutrons which is equivalent to a helium nucleus being released. Alpha decay occurs because there are too many protons‚ which causes

Early Childhood Caries (ECC)‚ also referred to as Baby Bottle Tooth Decay (BBTD)‚ is a disease that causes severe and swift decay of baby teeth. It usually begins with the upper front teeth‚ then moves on to the molars. Unfortunately‚ by the time most parents notice the decay‚ it may be too late to do anything about it. That’s why it’s important to understand the causes of ECC and learn how to prevent it before it even starts. WHAT CAUSES ECC? The main culprit of ECC is -- surprise -- your baby’s
