Analysis of the Research Article pH Effects on the Bio-Permeability of Polymers Used in Prophylactics - Essay ExampleThe hypothesis in this study was that pH has an effect on bio-permeability of NLR condoms hence research question is Does pH increase the permeability of NLR condoms to infectious agents? In order to get an help to the research question, this study tested pH effects on the permeability of natural latex rubber thus pH is an independent variable man permeability of NLR is a dependent variable. The investigators exercised adequate control of the variables. The NLR were first tested for any permeability using neutral water, bacteriophage and bacterium (E. Coli) and only those that were tight at the beginning of the experiment were used in the experiment. This was very important since it ensured the issuances that showed permeability after treating with different pH solutions were not as a result of any other factor but the pH. The second control was by cleaning the NL R condoms using distilled and neutral water. This was important because of two controls first, by ensuring all lubricants, flavors and outcome are removed from the NLR condom and second, there is no effect on the subsequent removal since distilled water (neutral was used) (Tubman et al 293-294). The investigators also prepared and standardized the bacteria that was used in this experiment and used the right media to inoculate and isolate the bacteria and bacteriophage. However, the investigators have not shown evidence of calibration of the pH meter that was used. Since pH is a variable, preparation of the pH solutions that were used to treat NLR condoms only is only mentioned but does not show for example how the study confirmed that pH 4.2 was in reality 4.2. Moreover, replication of this study could face a challenge due to this fact.
