 Abstract

In many institutions, information system is essential for ensuring efficiency in operations and accountability in financial operations. Access limitations into information communication systems - ICT in organizations has been found in various studies to contribute immensely to management of information systems security. Nonetheless, studies focusing on prominence of access control components in university and their levels of implementation in universities are still insufficient. This study was conducted in universities in Kenya, with the main objective of investigating the levels of implementation of key aspects of access control. Smiths sampling formula was employed to get a sample of 91 respondents. Questionnaires were used for data collection from staff members who were mainly section heads of user departments and information systems administrators. The data analysis produced statistical values needed to address the main objective. Results showed that while some features of access control are fairly implemented within universities in Kenya, many features are inadequately adopted. Therefore, it is recommended that universities fully implement access control measures for better security of information systems in universities. The study also recommends that information systems security policies should include key features of access control.

The World Health Organization (WHO) defines health as the state of perfect (complete) physical, mental and social well-being, and not just the absence of disease et al.,Gabriela Restrepo Rodas May 2020. The COVID-19 pandemic is a major health crisis affecting several nations, with over 45,000 cases and 13,699 confirmed deaths reported to date. In Rajasthan, 25,000 cases are reported. Such widespread outbreaks are associated with adverse mental health consequences. With strict preventive measures and restrictions by the Indian Government in the form of nationwide lockdown, the citizens are going through a range of psychological and emotional reactions, fear and uncertainty being one of them. This study was conducted with the aim of exploring the impact of COVID-19 and lockdown on the mental health of individuals. et al., Kashif Hasan Our study aimed to investigate the immediate impact of the COVID-19 pandemic on mental health and quality of life among the local people of different ages. An online survey was distributed through a social media platform between May and June2020. Participants completed a modified validated questionnaire they were mainly asked upon did they go through stress, anxiety and depression.

 Abstract

Machine learning has a great potential in healthcare industry in various tasks ranging from diagnosis to decision making. There are several machine learning algorithms available which are suitable for various tasks but selecting the best one is a challenge. For selecting the best algorithm, we conducted a study on supervised machine learning algorithms for detecting liver disease in patients. In this paper, we have discussed various supervised machine learning algorithms and analyzed performance of those algorithms for liver disease detection for Indian liver patient records. To implement the algorithms, Indian liver patient records data set was used with 583 instances with 10 attributes as independent variables and one as dependent variable for the analysis. From this research study, the results show that SVM gives the best results in liver disease detection as compared to Logistic Regression, K-Nearest Neighbours, Naive Bayes (NB), Random Forest and Neural Network algorithm.

 Abstract

Nanotechnology is arising as a field of modern science which finds its application in various fields such as medical, health care, food, industrial purposes, etc. due to their manufacturing of materials ranging in nanometres. The B. ceiba is a miraculous plant for the skin troubles and therefore it is selected for preparation of its nanoparticles. In topical formulations, antimicrobial nanoparticles are found effective for treating acne vulgaris and peel off formulations are recently trending in cosmetics. In the present study, biosynthesis of silver nanoparticles was achieved by reduction of silver nitrate using Bombax ceiba acetone extract. These biosynthesized silver nanoparticles were characterized by using UV- Vis spectroscopy, SEM and particle size analysis. Antioxidant and anti-microbial activity of nanoparticles and acetone extract was evaluated. The synthesized nanoparticles were then incorporated in the formulation and evaluated for its various physical parameters.

 Abstract

With the fast development of informal organizations and micro blogging sites, correspondence between individuals from various social and mental foundations turned out to be more straightforward, bringing about increasingly more "digital" clashes between these individuals. Thusly, loathe discourse is utilized to an ever increasing extent, to where it turned into a difficult issue attacking these open spaces. Loathe discourse alludes to the utilization of forceful, vicious or hostile language, It concentrates a specific gathering of individuals sharing a typical property, regardless of whether this property is their sex (i.e., sexism), their ethnic gathering or race (i.e., prejudice) or their accepts and religion, and so on. While the majority of the online interpersonal organizations and miniaturized scale blogging sites deny the utilization of loathe discourse, the size of these systems and sites makes it practically difficult to control the entirety of their substance. In this way, emerges the need to distinguish such discourse consequently and channel any substance that presents derisive language or language instigating to contempt. In this way to deal with distinguish despise articulations on Twitter. Our procedure relies upon unigrams and structures that are normally accumulated from the readiness set.

 Abstract

Brown seaweed Padina tetrastromatica is chief constituents of nutraceutical food and are regularly consumed by the Asian countries due to their large health benefits. Since earlier studies had been proved that P. tetrastromatica have pharmacological activities like antibacterial, antimicrobial, antifungal, antidiabetics, and cytotoxic activity. The present study was aimed to screen antioxidant activity of flavonoid rich fraction of P. tetrastromatica (FRPD). Extraction was done by maceration for 48 hours using methanol by modern sophisticated instruments. These extract was made into flavonoid rich fraction by partitioning with petroleum ether (60-800C) and n- hexane. The flavonoid rich extract was confirmed by phytochemical screening and the flavonoid contents are quantified by total phenolic and flavonoid content estimation. The total flavonoid and total phenolic content of the obtained fraction was found to be 174.71mg of quercetin equivalent, 246.28 mg GAE/g respectively. Antioxidant efficacies are also screened by DPPH and H2O2 radical scavenging assay and the total antioxidant capacity was also performed. The IC50 value of the antioxidant activity was found to be 121.92 ?g/ml, 254.73 ?g/ml, 190.99 ?g/ml respectively. This preliminary investigation might be useful to screen the plant in molecular levels.
