Group members tried to put certain liquids in a cuvette and then place it in the spectrophotometer and the waves would be constantly moving. This little problem made it difficult to get precise results of certain concentrations of the food dye. Conclusion: In the end predicting the amount of dye that was in the food dye could not have been correctly guessed. Not calibrating the spectrophotometer can really have an affect on the wavelength and absorbance calculations that are given. We had an error somewhere along the line when making the solutions for the yellow dye #5.
60 Days Risk-Free Trial Mike Whitfield has a decent refund guarantee in place, and he says that if you’re not happy with The Achievable Body system for any reason, you can simply ask him for your money back. We have to say that we tried searching for complaints regarding Mike’s refund policy, but we didn’t find any so far… The Cons Varied Results Like other weight loss programs, the results of The Achievable Body Blueprint could be different for each person. Some may lose as much as 11 pounds on the first week alone, while you may lose only 3 pounds or even less. Right
The starch concentration was calculated using the absorbance and the equation of the standard curve (Figure 1) (see Calculations). Table 2 lists the results of the calculated starch concentration in grams per liter. To determine if the outcome of both experiments were accurate, we should have replicated the procedure to compare the results. Because we only prepared the experimental procedures once, the results could contain some deviation if performed again. Conclusion Supplement one, GNC, was found to not contain proteins and its starch proportion was 0.0745 g/L; this supplement is not recommended due to the absence of amino acids and high starch content.
Two of the samples were the same and one was odd. The odd sample contained oleic acid (C18:1). The panelists were asked to choose the odd sample in each set. Triplicates of samples were used in triangle test was due to the chance of correctly guessing the sample with added fatty acids three consecutive times in triangle test was only 3.7% (Stewart and others 2011). Although fatty acids was not a ‘taste’ in the traditional sense such as sweet, however, previous research had proved that fatty acids can be detected in the oral cavity over a range of concentration (Mattes 2009).
Despite the titration being performed thrice to attain the average titrant which would help improve accuracy, several errors happened contributing to inaccuracies. Some of these are misjudging the colour at endpoint and inaccurate reading of the volume in the burette due to parallax error or presence of air bubbles, which resulted in the amount of titrant recorded to be inaccurate. Also by using the same pipette for different solutions without rinsing it with D.I. water in between and when addition of solid reagents, not all the reagent may have been added both contributing to error leading to slight inaccuracies. To further increase accuracy, solutions that were involved in the reaction with iodine should be
The fungal cultures which grown earlier on Petri dishes were transferred to the rice (2 Petri-dishes/plastic bag) under sterilized conditions. The bags then closed and kept under 25-30°C for 15 days. After that the rice was dried on strengthening paper and then grinded. Then 50 grams of ground rice inoculated with Conidiospores of, T. album fungi was added to (1 kg) of wheat. Each gram of rice powder loaded with fungus contained (7x107 conidia /ml) which considered the highest concentration that gave the highest mortality rate in previous bioassay experiment, then the treated wheat with T. album in addition to control wheat were infested with an insect, R. dominica an early stage of the infection and stored in plastic jars (1 liter) covered with muslin cloth at 25±1 ºC and 80-90% RH for six months.
Outliers There were two major outliers in the data. One of them was trial 3 of the control test, which took 47.38 to fully drain. It’s an outlier because the other two trials of the control test took 35 and 39 seconds to fully drain, so trial 3 isn’t in the range that was expected of it. The other outlier was trial 3 of the sample test, which took 67.6 seconds to fully drain. It’s an outlier because the other two trials both took 53 seconds to fully drain, and like the other outlier, it wasn’t in the expected range.
Omnivorous birds put their eggs in one basket A latest research published in Nature produced astonishing results – Birds that are omnivorous have lower diversification rates – higher risks of extinction and are less likely to evolve to different species Few studies had been done to establish the connection between diet and evolutionary processes. A study conducted recently on birds obtained critical information showing the links between diet and evolution. The surprising results will have deep repercussions in the field of Biology. It can possibly be the key to unlock the secrets of why some species goes extinct and why some diverge into different species. What an organism eats is associated to how it interacts with its environment.
Synthesis Essay Rough Draft Obesity can be seen as the epidemic of the twenty-first century as it poses a threat to a large percent of the current population, and like all epidemics, there is a suspected cause, “Food deserts.” This term is a technical term used by the CDC to describe an area that lacks access to foods high in nutrients, such as specific areas without grocery stores nearby. The idea of “food deserts” is paradoxical and can be seen as holding back people who want to eat healthy food, but it also has little impact on those who do not already want to eat healthily. For the past decade, researchers and professionals have done surveys and studies on the possibility of “food deserts” being the cause of obesity and yielding different results. However, there is also the complication that obesity is an epidemic caused by a dynamic group of factors and cannot be pinned
The extension of control pulse width is from 0.5 ms to 2.5 ms. The stall torque is 12.0 kg/cm. The velocity is 0.24 sec/60degree. The steering gear is droved by pulse-width modulated (PWM) signal. That is to say if the input of 0.5~2.5 ms VOH pulse width in the 20 ms control cycle, the corresponding angle is -90°~ 90°.
