Leafy greens Yes‚ they’re your favorite go-to salad greens—lettuce‚ escarole‚ endive‚ spinach‚ cabbage‚ kale‚ arugula‚ and chard. But they also caused 363 outbreaks involving 13‚568 reported cases of illness since 1990. (Remember bagged spinach in 2006?) Greens can be contaminated by manure‚ dirty water rinses‚ or unwashed hands before you even purchase them. To avoid getting sick‚ wash produce and prevent cross-contamination

minimized by adopting shortwall method of working at the time of pillar extraction. In India some of the underground mine adopting this method at the time of depillaring and percentage of extraction is very high and production rate is also encouraging. So we should adopt this method in all underground mines where geomining condition support. Keywords Longwall‚shortwall‚depillaring. Introduction: Mining is the extraction of valuable mineral or any other geological mineral from the earth. The

Extraction of Caffeine from Lipton® Tea Leaves Nathaniel Camangon*‚ Kaila Bumagat‚ Franz Mari Burgos‚ Remigio Callanta Department of Chemistry‚ College of Science‚ University of Santo Tomas‚ Manila‚ Philippines Abstract This experiment mainly focuses on the extraction of pure caffeine by multiple extraction from commercially acquired tea leaves and determining its purity by melting point determination. A 0.02% yield of pure caffeine was obtained from 10.4978g of tea leaves (4 tea bags).

Strawberry DNA lab Extraction Purpose: The purpose of this lab experiment is to see if this particular type of fruit which in this case is a strawberry contains DNA. Using materials such as a Ziploc bag to help keep the entire strawberry in one place while it gets smashed and test tube to help better see the DNA and break down of the liquid in the left over strawberry sediments. Background information: The long thick fibers of DNA store the information for the function of the chemistry

benzoic acid and a neutral compound (triphenylmethanol or 1‚2‚4‚5-tetrachlorobenzene) into its components by extraction and also to get the melting point. THEORY: Extraction is a process of transferring a solute from one solvent to another. In this experiment‚ a mixture of benzoic acid and a neutral compound (triphenylmethanol or 1‚2‚4‚5-tetrachlorobenzene) into its components by extraction. The mixture is dissolved in diethyl ether (common name is ether). Both components are soluble in this solvent
