Most heavy metals from industrial catalysts are harmful to human body; however, to function normally, the human body does need traces of essential metal cofactors. The data confirms that complexes between cobalt ions and deprotonated histidine will only settle into a square planar geometry, regardless of the initial geometry. However, with neutral histidine, the complex is not in square planar formation at all. Instead, the five-member ring formed among cobalt and histidine’s N- and C-terminus forms an angle, where N-Co-N is almost linear (167.5°). Different reaction conditions will yield either tetrahedral and square planar geometry at the metal center, which will influence the band gap. Such influence can then be used to create a tunable and broad spectrum solar panel materials.

This study analyzed images of the established Keratitis pneumococcal mouse model. The eye images of mice 7-8-week-old and 9-month-old were collected. Additional images were taken on post-infection days one, three, five, and nine, revealing the progression of the infection. Results: The ImageJ Application provided more in depth review to determine the detrimental effects of S. pneumoniae. Through the software, a “Color Threshold” was created on every image to emphasize the area of damage caused by the bacteria. ImageJ has proven to be a useful tool to analyze the impact of disease on the murine model. Results from this study also provide evidence of the importance of early intervention in ocular disease.

Sub-Saharan African countries are plagued by an adaptable parasite, Trypanosoma brucei, T.b., with a very high iron dependency. This protozoan parasite is the causative agent for Human African Trypanosomiasis (HAT), otherwise known as sleeping sickness. Any process, which contributes to further decreasing DHAP concentration, is likely to be detrimental to the T. brucei. Other processes, such as superoxide radical degradation, will be considered in concert to the ones assessed in this study to develop suitable drug targets.

Annually farmers in the United States suffer crop losses due to the invasive weed, Amaranthus palmeri. Agricultural Vinegar (vinegar with 20% acetic acid) is an effective, non-selective organic herbicide. Overall, the experiments show that if caught early enough, with in the first 30 days, the young A. palmeri may be treated with applications of 10% acetic acid or 20% acetic acid regardless of its glyphosate resistance. This is beneficial for the environment because it will decrease the buildup of acetic acid in the soil. This minimizes the chance for making the soil and surrounding environment more acidic. It also brings down the price per acre of producing produce. This in turn brings down the price at the supermarket. Future work can refine what concentration between 10 and 20% remains effective, and further analysis of how the herbicide affects the soil could also lead to more discovery, optimization and further savings.
