Page 1 & 2 Question of Interest- Out of tin foil‚ a plastic baggy and saran wrap‚ which preserves a piece of fruit the best after a week? Population of interest- The population of interest is the pieces of fruit we are using. The fruit is what we are experimenting on. Experimental Design- For our experiment‚ we chose three types of fruit to put into the three different wrappings. We did this so that we could have replication. The fruits we used were strawberries‚ apples and bananas

DCS ULO Relatieve respiratie Ethanol!! 0 % O2 21 TM Dynamic Control System With the DCS™ system the lowest possible oxygen value during storage is sought instead of the ‘safe’ 1% oxygen. When the apple starts to ferment automatically a permanent minimal flow of oxygen is supplied. By this method apples are stored in the best possible way. O2 / CO2 CONTrOL SENSOrS O2 CO2 Ethanol New for DCS™ With special systems alcohol formation is determined manually by e.g. cutting apples into pieces

From the 80s‚ plastic bags became popular because of its thinness and almost weightless. Plastic bags are made from polyethylene and they are used for many purposes such as medical application‚ daily groceries carrying. Within the banana supply chain‚ plastic bags are utilized since the very in many stages for example at the packaging station‚ the bananas will be packed into cardboard boxes with an inlay of a plastic bag or at the wholesalers‚ three to five bananas will be wrapped in one plastic

Petrochemicals Workforce Development Petrochemicals Workforce Development Introduction The North American petrochemical industry can be said to be currently enjoying something of a renaissance. With natural gas prices currently low‚ and looking set to remain that way due to abundant domestic shale supply‚ companies and investors are putting up billions of dollars for construction‚ expansion and export projects across the US and Canada. One real hotspot for such activity can be found on the Gulf

yesterday at the market I noticed a number of workers‚ least bothered by the pungent smell that fills the area‚ are busy putting small packets in hundreds of crates‚ two in each‚ containing fresh green mangoes. “This is ‘carpet.’ By the time the fruit will be transported to different markets in the country‚ it will have ripened and will fetch a good price . About 300 to 400 trucks carrying around 8‚000 tons of mangoes arrive every day at the Mandi these days. Talking about the large-scale use

The gaseous hormone ethylene has been shown to influence a diverse array of plant growth and developmental processes‚ thus it is critical for plants to optimize the ethylene production at developmental transitions as well as during stress response. Ethylene is derived from the amino acid methionine‚ which in the first step is converted to S-adenosyl-methionine (AdoMet) by AdoMet synthetase3‚4. The 1-Aminocyclopropane-1-Carboxylic acid Synthase (ACS) catalyzes the conversion of AdoMet to 1-aminocyclopropane-1-carboxylic

INTRODUCTION 1. INTRODUCTION The copolymerization of ethylene with 1‚ 3-butadiene to give crystalline‚ homopolymer-free‚ high molecular weight‚ substantially linear copolymer is described. Butadiene polymerizes almost exclusively in a trans-1‚ 4 structure‚ ranging in content from zero to 50 mole-%. At relatively low content of butadiene monomeric units (≤30 mole-%) X-ray crystallinity is of polyethylene type with a slight variation of the structural parameters. At higher levels of

1 HISTORY: Ethylene Glycol (1‚ 2 – ethanediol)‚ HOCH2CH2OH usually called glycol is the simplest Diol. Diethylene glycol and Triethylene glycol are Oligomers of Mono ethylene glycol. Ethylene glycol was first prepared by Wurtz in 1859; treatment of 1‚2 dibromoethane with silver acetate yielding ethylene glycol diacetate via saponification with potassium hydroxide and in 1860 from the hydration of ethylene oxide. There to have been no commercial manufacture or application of ethylene glycol prior

The amount of solute decreases the boiling point. The pressure keeps the atmospheric temperature lower than the pressure with the solute. Antifreeze used in heating and cooling systems is a solution of water and ethylene glycol has a lower freezing point than pure water or pure ethylene glycol. Antifreeze is a good example of the colligative property‚ except its special because it keeps from
