Use of Unmanned Aircraft Systems and Regulatory Landscape: Unravelling the Future Challenges in the High Sky
The individuals on the ground nowadays often observe objects distantly hover over the sky, which raises the question of who might be operating the object or what the object might record. Unmanned Aircraft Systems (UAS) or Drones today have quickly penetrated civilian, military, and commercial sectors. The drones or UAS, with the advancement of technology, are now capable of traversing long distances, having long endurance, and having multipurpose functionality. The UAS industry is fast expanding, with trade investment touching the billion-dollar mark in flourishing economies. The advent of the Covid 19 pandemic saw a steep rise in the use of UAS across the world. The world is moving towards a liberalized regulatory approach to promote and accelerate the UAS within the aviation ecosystem. The UAS ecosystem provides access to advanced aircraft technology coupled with vast economic opportunity, but the same is not devoid of challenges. The study looks at aspects of privacy, persistence surveillance, data protection, and safety that have emerged as pertinent challenges to the UAS ecosystem. The study has analyzed the case laws that have influenced the regulatory approach, policy initiatives. The study has also looked at stakeholders’ initiatives to navigate the challenges to strengthen the UAS ecosystem
A Study on Stock Co-Movement’s Analysis of Select Bank and IT Company Stocks
The risk of a portfolio depends on the co- movement between the security returns forming the portfolio. The coefficient of correlation is an important measure for studying co movement between securities. Banking and IT company’s shares represent sizable share of market portfolio of common investors. In this perspective the present study has been undertaken to help small retail investors who commonly invest in these two major sectors to understand the co movement of returns among Banking and IT industry stocks. This study covers correlation co movement calculation between selected four Banking shares and four IT companies’ shares for a period from 16th June 2014 to 15th June 2015. The correlation between banking shares are more positive compared to correlation between IT company shares. This implies that the banking stocks return more or less move in the same direction. The correlation between Banking and IT Company stocks are either zero or negative which implies that these two sectors shares are not related or move in the opposite direction in terms of return. This implies that banking and IT industry shares are good combinations for portfolio construction which substantially reduces the risk of that particular portfolio
Occurrence and abundance of plastic particles in razor moonfish along the eastern Arabian Sea
Rising crisis in marine environment is the presence of plastics in the water column and risk of their input and accumulation in the food web. The present study reports for the first time, the presence of micro and macro plastics in the gut of razor moonfish, Mene maculata. Moonfish plays a major role in the marine food web as prey of large pelagic fishes. The gut analysis of fishes collected from commercial vessels operating along eastern Arabian Sea was analysed to determine the occurrence and abundance of plastic particles with attempt to identify the diet component which might have contributed to the plastic intake in fish. The analysis revealed dominance of plastic particles in gut when dietary component was dominated by eggs. The present study forms baseline information for plastic accumulations in fishes along the eastern Arabian Se
Do African-American men need separate prostate cancer screening guidelines?
BACKGROUND: In 2012, the United States Preventative Services Task Force issued new guidelines recommending that male U.S. residents, irrespective of race, no longer be screened for prostate cancer. In African American men, the incidence of prostate cancer is almost 60 % higher and the mortality rate is two to three times greater than in Caucasians. The purpose of this study is to reduce African American men's prostate cancer burden by demonstrating they need separate screening guidelines. METHODS: We performed a PubMed search using the keywords: African American, Prostate cancer, Outcomes, Molecular markers, Prostate-specific Antigen velocity, PSA density, and to derive data relevant to our hypothesis. RESULTS: In our literature review, we identified several aspects of prostate cancer that are different in Caucasian and African American men. These included prostate cancer incidence and outcome, the clinical course of the disease, serum PSA levels, genetic differences, and social barriers. It's also important to note that the USPSTF guidelines were based on two studies, one of which reported that only 4 % of its participants were African American. The other did not report demographic information, but used participants from seven European countries with small African American populations. CONCLUSION: Given the above, we conclude that separate prostate cancer screening guidelines are greatly necessary to help save the lives of African Americans

Increasing reproductive health services through Family PACT participation among California community college student health centers
ObjectiveCommunity college students engage in more risky sexual behavior compared to their four-year counterparts, yet have access to fewer reproductive health services. The study's purpose was to examine whether California Community College student health centers' participation in Family PACT, a state publicly-funded family planning program, increased reproductive health services to community colleges students.ParticipantsCalifornia community college student health centers.MethodsBivariate analyses of student health centers with and without Family PACT participation and qualitative analysis of five participating campuses.ResultsAmong the 60 colleges in the study, 25 student health centers participated in the Family PACT program. Family PACT campuses reported greater provision of sexual and reproductive health services and higher levels of staffing and revenue.ConclusionsKey benefits of Family PACT participation among community colleges include expansion of sexual and reproductive health services to an underserved population and increased student health centers' financial sustainability
A Morphometric Study on the Septomarginal Trabeculae in South Indian Cadavers
ABSTRACT Most of the human hearts presents a specialized bridge known as Septomarginal trabecula which extends from the right side of the ventricular septum to the base of anterior papillary muscle. For the present study we took 30 human hearts. We studied the thickness of the septomarginal trabecula, the height of its attachment to the ventricular wall by considering the supraventricular crest as the landmark, length of septomarginal trabecula and type of attachment to the septal wall. We found that in most of the cases, the septomarginal trabecula originated about upper or middle third of the ventricular wall. The thickness varied from less than 1mm to more than 5mm. We also found variation in the way of attachment of the septomarginal trabecula to the ventricular wall. Some of the septomarginal trabecula branched before attaching to the base of the anterior papillary muscle. We decided to study this because of its role in the haemodynamics and conduction of electric impulses in heart
Molecular implications of HOX genes targeting multiple signaling pathways in cancer.
Homeobox (HOX) genes encode highly conserved homeotic transcription factors that play a crucial role in organogenesis and tissue homeostasis. Their deregulation impacts the function of several regulatory molecules contributing to tumor initiation and progression. A functional bridge exists between altered gene expression of individual HOX genes and tumorigenesis. This review focuses on how deregulation in the HOX-associated signaling pathways contributes to the metastatic progression in cancer. We discuss their functional significance, clinical implications and ascertain their role as a diagnostic and prognostic biomarker in the various cancer types. Besides, the mechanism of understanding the theoretical underpinning that affects HOX-mediated therapy resistance in cancers has been outlined. The knowledge gained shall pave the way for newer insights into the treatment of cancer
