A New Graph to Display the Epidemic Outbreaks of Covid-19 in the World

Abstract:

The paper proposes a new visualization scheme for the registry of Covid-19 cases by calculating the mantissa of the registered ones, so there is no need of performing complicated mathematical calculations. As an example, six countries are randomly selected: Australia, Brazil, China, Colombia, Portugal and Venezuela. The results show that China is the only country that keeps the epidemic under control, while Australia begins a new outbreak after having previously controlled the epidemic. Colombia and Portugal show a very similar behavior of registered cases and, finally, we can see that Venezuela, Brazil, Portugal, and Colombia present a growth of cases that may trigger new outbreaks in the future. Results are obtained from data registered at Johns Hopkins University until July 18^th, 2020.

Covid-19 Pandemic: Mental Dynamics of Quarantine and Social Isolation

Abstract:

This paper explores the two major preventive concepts of the unpredictable life-threatening viral infection caused by Coronavirus that is ravaging the entire world from the beginning of the year 2020, as it pertains to mental health. Through scientific consultations, the expectation is that effective vaccine for the Coronavirus disease-2019 (COVID-19) may not come into the market this year. Two (among others) preventive measures, namely Social Distancing and Quarantine are suggested by the World Health Organization (WHO). Using the principle of explorative research, this study established the flipside of quarantine and social distancing from the metal health perspective. It was discovered that there is a relationship between a long period of self-isolation and a high probability of concerned persons having anxiety, stress, and depression, which gradually leads to mental and emotional health issues. Consequently, mental health affects the overall health and affects...

Osteoarthritis and Falls: Is there a Link?

Abstract:

Osteoarthritis, a widespread joint disease, commonly results in considerable pain and functional disability, especially among older adults. At the same time, falls and fall injuries, also common among the older population, may not only contribute to the onset of osteoarthritis, but once established, to falls that lead to fractures and disability in their own right. But what does the research show specifically?

Sleep Disturbances and Hip Fractures

Abstract:

Hip fractures, which remain highly prevalent among the elderly and produce enormous social and economic costs, have not truly abated in prevalence despite years of research that outlines a multitude of preventable risk factors and intervention programs. This review aimed to examine if sleep disturbances have a bearing on the risk of incurring a hip fracture directly or indirectly, among older adults. The specific aim was to explore and summarize what we know, and how this might inform future research and practice. To this end, PUBMED, Web of Science, Scopus, and Google Scholar data bases were searched to uncover available data representing the topic of sleep in relation to hip fractures among the elderly. Articles of note were scrutinized and summarized in narrative form. Results showed very few studies on the topic prevail, even with no restriction on years examined, and of these, discordant, rather than any solid uniform conclusions prevail. It is concluded ther...

Rate, Maternal and Fetal Outcome of Cesarean Delivery Performed by IESO at Shenen Gibe General Hospital, Jimma South West Ethiopia: A Descriptive Retrospective Data

Abstract:

Pregnancy and parturition are events of considerable significance in the life cycle of women. Though it is supposed that the quality of care during labor, birth, and postpartum period plays a great role for adverse outcomes of birth, various reports claimed that cesarean delivery carries a higher maternal and fetal morbidity and mortality compared to vaginal delivery. Therefore, this study assessed the Rate, Maternal and Fetal Outcome of Cesarean delivery performed by IESO at Shenen Gibe General Hospital, Jimma south west Ethiopia. Integrated Emergency surgical officer is a health professional qualified and authorized to perform emergency obstetrical-gynecological and emergency general surgical procedures. The training has started in 2010 in 3 universities and 10 affiliated sites with intake of 43 students. The MSc program in integrated emergency surgery is intended to achieve one of the millen...

Abstract:

Antimicrobial stewardship (ASP) is of the utmost importance as a way to optimize the use of antimicrobials to prevent the development of resistance and improve patient outcomes. So, it is worthwhile to assess the knowledge, attitude and awareness regarding antimicrobial stewardship in hospitals.

Determining the Efficiency of Fuzzy Logic EOQ Inventory Model with Varying Demand in Comparison with Lagrangian and Kuhn-Tucker Method Through Sensitivity Analysis

Abstract:

This paper considers an EOQ inventory model with varying demand and holding costs. It suggests minimizing the total cost in a fuzzy related environment. The optimal policy for the nonlinear problem is determined by both Lagrangian and Kuhn-tucker methods and compared with varying price-dependent coefficient. All the input parameters related to inventory are fuzzified by using trapezoidal numbers. In the end, a numerical example discussed with sensitivity analysis is done to justify the solution procedure. This paper primarily focuses on the aspect of Economic Order Quantity (EOQ) for variable demand using Lagrangian, Kuhn-Tucker and fuzzy logic analysis. Comparative analysis of there methods are evaluated in this paper and the results showed the efficiency of fuzzy logic over the conventional methods. Here in this research trapezoidal fuzzy numbers are incorporated to study the price dependent coefficients with variable demand and unit purchase cost over varia...

Prevention of Aging and Improvement of Longevity and Life-Span in D-Galactose Induced Aging Rats After Treatment with the Biofield Energy Per Se and Biofield Treated Proprietary Test Formulation

Abstract:

The study was aimed to investigate the potential benefits of the Consciousness Energy Healing Treatment (the Trivedi Effect^®) per se and Biofield Energy Healing treated novel test formulation in male Sprague Dawley rats for their antiaging activity by monitoring aging biomarkers such as brain-derived neurotrophic factor (BDNF), silent information regulator-1 (SIRT-1), and klotho protein. The test formulation was distributed into two parts. First part did not provide any Biofield Energy Treatment was denoted as the untreated sample, however the second part was received Biofield Energy Healing Treatment by a renowned Biofield Energy Healer, Mr. Mahendra Kumar Trivedi and defined as the Biofield Energy Treated sample. In this experiment, nine groups (n=10) were assigned, in which four were preventive maintenance groups. Among them, three groups of animals were also received Biofield Energy Healing Treatment per se...

Reactive Stepping Responses Mediated by Predictable Manual Waist-Pull Perturbations are Associated with Fall History in Older Adults

Abstract:

The ability to respond effectively to perturbations is a key element of reactive postural control and is a crucial mediator of falls. Several studies exist in the literature that determine older adults’ responses to perturbations, however those studies typically involve procedures that lack objectivity or applicability outside a laboratory. A study involving waist-pull perturbations with a spring-scale (SS) is an exception. In that study, fall history was most accurately differentiated by a reactive stepping response to a perturbing force of 10% total body weight. Using data from that study, we retrospectively examined the association between fall history and the number of steps accompanying a SS perturbing force of 10% total body weight in older adults. For perspective, the association of fall history with Timed-Up-and-Go (TUG) and single limb stance (SLS) times was also determin...

Cloning, Expression and Characterization of the α-glucuronidase from the Hyperthermophile DictyoglomusturgidumDSM 6724Ô

Abstract:

Conversion of biomass into fermentable sugars is a major requirement for successful and cost-effective biofuels production. The conversion of xylan to sugars requires multiple enzymes including α-glucuronidase. Here we report the cloning, expression, purification and characterization of the α-glucuronidase from Dictyoglomusturgidum(DtuAgu). DtuAgu is an intracellular protein of 685 amino acids and a predicted molecular weight of 79.4 kD. Enzymatic activity was optimum between pH 7.0 and 8.0 and at 85°C. The specific activity of the enzyme was 10 u/mg when measured using mixed aldouronic acids. The specific activity on isolated glucuronoxylan was approximately 20% of the value obtained with xylooligosaccharides. DtuAgu significantly improved xylan conversion to xylose when evaluated using two mixtures of thermostable bacterial enzymes and two sources of xylan. DtuAgu has the potential to be a key player in t...
