Water System for Developing Countries / Disaster Relief Made with Local Materials

At the beginning of this project, I elected to focus mainly on the electrolysis portion. I completed a lot of research on electrolysis in general, and then specifically on brine electrolysis, which is transforming a salt water solution into a sodium hypochlorite solution, or bleach. I researched all of the different types of electrode materials and purchased several electrodes in order to perform experiments. I researched several methods of electrolysis in use today. I performed several calculations about the electrolysis reaction, including the electric potential required to drive the reaction (approximately 1.0 volt), as well as what concentration of salt to use for the water and the expected final concentration of the bleach solution that would be created. Based on sources given to us in the Phase I proposal, a salt concentration of 3% by weight was chosen, and this translates to a 0.513M solution. Due to the stoichiometry, this indicates that the highest concentration of sodium hypochlorite solution that was possible was also a 0.513M solution. Based on the electric potential, I ranked what I thought would be the best pairings of electrodes, and I planned how to carry out the experiment. The “best” theoretical pairing of electrodes was the copper and aluminum pairing, because the potential difference between the two metals was the highest, at 2.01 volts. After that failed, I purchased new electrodes with special coatings that were already in use for this type of application and carried out experiments with these electrodes. I performed every electrolysis experiment, recorded data, and drew conclusions about the data I recorded. I determined what the optimal time to run electrolysis was based on the batch size we selected. I took the graphs depicting the data from the treadle pump, sand filter, battery charging, and electrolysis experiments, edited them, and inserted them into the final paper. Although many group members assisted in writing the paper, I went through it and meticulously edited it for both content and grammar. I also filmed the footage we needed for the instructional videos. I assisted with the overall design of the water purification system, including what materials to use, what the size of batches should be, and how we would keep the water clean in the final reservoir. I spoke with a Civil Engineering professor regarding how clean the water must be to kill the microbes we expected to be present in the non-potable water, and we decided to use a chlorine residual of 1-5ppm based on her recommendation. I also spoke with two Chemical Engineering professors to learn more about the electrochemistry of the electrolysis reaction and to consult when I was having problems with the experimentation. I assisted in doing research in other areas of the project, including discrediting the idea of using a scotch yoke, and coming up with an alternative plan. I investigated the use of an alternator to charge the 12 volt battery using a bicycle, and when that failed, I researched about using the DC motor from a scooter to charge the battery using a bicycle

Effects of Early Life Stress on Anhedonia and Striatal Dopamine Concentration Depends on Variation in catechol-O-methyltransferase (COMT) Genotype

Depression is a serious, costly, and heterogeneous disorder for which no one genetic determinant has been identified. Research has shown that stress, and subsequent hypothalamic-pituitary-adrenal (HPA) axis dysregulation, is a significant predictor of depression, and one particular stressor that has been linked to vulnerability to depression and HPA axis dysregulation is early life trauma. Due to the heterogeneity and complexity of depression, it is likely that specific gene-environment interactions play a role in the development of depression. Interaction between catechol-O-methyltransferase (COMT) Val158Met variants with specific environmental factors can potentially increase vulnerability to depression. The present proposed experiment examines the interaction between COMT genotype and the effects of early life stress in a maternal separation paradigm on behavioral and neurological factors in a rodent model of depression. Outcome measures include anhedonia-like behavior, as indexed by performance on a sucrose consumption test, and striatal dopamine concentration, a neurological measure of depression. I hypothesize that across genotype, stress leads to decreased sucrose consumption and decreased striatal dopamine concentrations. However, the functional COMT Val158Met polymorphism will interact with stress such that these results are most pronounced among stressed Met/Met rats, as compared to Val/Met rats and Val/Val rats. These results may have implications for treatment of depression in COMT polymorphic individuals, who appear to be more sensitive to stress and more vulnerable to developing depression

A Study on Anti-Maskers

In-depth interviews were conducted in September of 2021 with 15 Florida residents between the ages of 18-30 (8 males, 7 females). Our primary goal was to identify why these individuals choose not to wear face masks when required or highly recommended despite the potential legal, social, and health consequences. The researchers discovered that these individuals frame not wearing masks as physically harmless, and socially and legally acceptable. Specifically, these individuals justify their anti-masking actions using seven patterns arising from both their internal views and external influences. These patterns are: 1) Changing CDC mask wearing recommendations, 2) Mask wearing health consequences, 3) Denial of the severity of the virus, 4) Right to choose, 5) Florida living 6) Media influence, and 7) Others are not wearing masks. We discuss the limitations to the study and conclude with recommendations for those who are proud maskers in addition to a discussion providing further ideas for study

Probable Early-Onset Alzheimer's Disease in an Apolipoprotein E2 Homozygote

Objective: To describe a case of early-onset Alzheimer's disease (AD) in an apolipoprotein (Apo) epsilon 2/epsilon 2 homozygote. Background: Apo epsilon 2/epsilon 2 is the rarest of the ApoE genotypes, representing only 1.4% of the population. Cognitive decline in ApoE epsilon 2 homozygotes has rarely been reported. Case Report/Methods: We report a 58-year-old Apo epsilon 2/epsilon 2 female who meets clinical criteria for probable AD as confirmed by neuropsychological testing, positron emission/computed tomography scan, CSF analysis and genetic screening for known mutations. Results: The clinical course is typical of AD, with progressive cognitive and functional decline. Conclusion: Clinically confirmed early-onset AD is atypical in ApoE2 homozygotes but can occur.

African Statue of Liberty

Tybee Island is situated at the mouth of the Savannah River, which leads to the city of Savannah. As ships arrived in North America with enslaved men, women, and children they were inspected at Tybee Island for signs of illness, and disease in order to hinder the spread of infectious diseases from overseas. As shipments increased a demand for a quarantine hospital arose. In 1766 lawmakers in Savannah authorized a budget of seventy pounds to seek a location to serve as a receiving juncture for incoming ships. The seventy pound budget was used to purchase 104 acres on the west end of the Island from plantation owner Josiah Tattnall, and construction began. Once complete, the hospital was named “Lazaretto” descending from the Italian word for “pest house.” Tybee Island officially recorded only two ships that disembarked enslaved Africans, totaling three hundred and fifty eight, of the four hundred and sixty two who embarked in African locations. However, Tybee received thousands more for quarantine before it was demolished in 1785.

Woman-centred care and integrated electronic medical records within Australian maternity settings: Point prevalence audit and observational study

Objective: Transition to paperless records brings new challenges to midwifery practice across the continuum of woman-centred care. There is limited and conflicting evidence on the relative benefits of electronic medical records in maternity settings. This article aims to inform the use of integrative electronic medical records within the maternity services’ environment with attention to the midwife-woman relationship. Design: This descriptive two-part study includes 1) an audit of electronic records in the early period following implementation (2-time points); and 2) an observational study to observe midwives’ practice relating to electronic record use. Setting: Two regional tertiary public hospitals Participants: Midwives providing care for childbearing women across antenatal, intrapartum and postnatal areas. Findings: 400 integrated electronic medical records were audited for completeness. Most fields had high levels of complete data in the correct location. However, between time 1 (T1) and time 2 (T2), persistent missing data (foetal heart rate documented 30 minutely T1 36%; T2 42%), and incomplete or incorrectly located data (pathology results T1:63%; T2 54%; perineal repair T1 60%; T2 46%) were identified. Observationally, midwives were actively engaged with the integrative electronic medical record between 23% to 68% (median 46%; IQR 16) of the time. Conclusion: Midwives spent a significant amount of time completing documentation during clinical episodes of care. Largely, this documentation was found to be accurate, yet exceptions to data completeness, precision and location remained, indicating some concerns with software usability. Implications for practice: Time-intensive monitoring and documentation may hinder woman-centred midwifery care
