Yield

disorders, & more hunger. The world starves while large biotech companies sit on their huge bags of cash. Genetically Modified foods have been used to theoretically conserve water, soil, and energy while producing greater yields. There is evidence to suggest that GMO foods do not always yield more and don’t solve world hunger. Consumers need to stop buying GMO foods because they cause disorders, cross pollinate non-GMO crops, and pollute the environment. GMO foods have been linked to many…

being practiced today in other developing countries have resulted in yield increases backed by methods containing GMOs have shown little to no increase in yields at all. Based on evident research from the Union of Concerned Scientists’ report Failure to Yield the definitive study to date on GM crops and yield. Failure to Yield is the first report to closely evaluate the overall effect genetic engineering has had on crop yields along with other researched agricultural technologies. The…

pure benzil and benzilic acid. Table 1 also shows the percent yield of each of these compounds. Table 2 provides the melting point results from the DigiMelt apparatus, which were used to test the purity of the experimental products. The percent yield of the crude product of benzil was calculated to be 73%. The melting point of the crude product of benzil was 82.0-86.2˚C, with a range of 4.2˚C. After evaluation of the high percent yield and comparison of the experimental data to literature…

The yield of oil extraction was compared between both method which is microwave assisted extraction method and soxhlet extraction method. Two different solvent was used in soxhlet extraction method which is polar solvent and non-polar solvent. The oil yield from soxhlet extraction method for 8 hours by using Methanol is 50% while Hexane is 81.82%. The oil extracted from microwave…

money to afford new seed, and thus need to keep increasing their yield. The issue of seed patenting and commercialization also poses significant problems in developing areas, where GM seeds, through competition and contamination, are slowly destroying the diversity of seed that once existed. If an entire agricultural sector is based on one type of crop with one specific genetic makeup, when the crop fails or does not have profitable yields on any given years, it puts the livelihoods of poorer…

To ensure the reaction was complete the melting point was obtained and determined to be 128℃. The limiting reagent for this reaction was determined to be benzaldehyde as it was a 2: 1 ratio. Using the theoretical yield of 20.70 g, the percent yield was calculated to be 28.74 %. This could have been higher if the reflux was completed for 90 minutes like the procedure called for instead of 60 minutes. This could have influenced the amount of product obtained from the reflux. The…

condensation in high to excellent yields at 70 °C under solvent-free conditions. Initially the reaction between 2-aminobenzophenone (1.0 mmol) and dimedone (1.0 mmol), as the model reaction was examined in the presence varying amount of tartaric acid as catalyst and the results are presented in Table 1. The best result was achieved by carrying out the reaction with 15 mol% of catalyst (Table 1, entry 4). Use of a higher amount of catalyst did not improve the yield while a decrease in the amount…

Fitzsimmons raised many different questions during his talk on integrated aquaculture-agriculture. The most prominent question was if we can use integrated aquaculture-agriculture to supply both higher crop yields and an alternative protein source? Not only does using an integrated system increase crop yields significantly, but it also farms an alternative protein source for the American public. As we look towards the future, using an integrated system will help provide the crops and protein we…

Solventless Reactions: The Aldol Reaction CH204-01 Fadwa Mekkaoui Introduction: An aldol reaction is the formation of a new carbon-carbon bond by the addition of a nucleophile to an electron deficient carbon. The reaction is favorable in Green Chemistry. It demonstrates green principles such as using no solvent and having a high atom economy. In the lab a mixed aldol reaction was performed to synthesize an unsaturated ketone from and aldehyde and ketone. By using an aldehyde, that doesn’t…

ethanol. IR- and H- NMR-spectrum were taken to determine the location of the I+. I had a yield of 0,7 g (2,66mmol, 18,2%). The iodide’s position is opposite of the –OH group. Salicylamide…
