Work Allocation Algorithm (WA2): An Operations Research Approach []

The objective of this paper is to deep dive into Linear Programming (LP) approach for solving “Optimal allocation of work mix in a cross-training environment”. One need that is often practiced by industries is to come up with optimal number of resources required to run the operations without compromising the customer service. This paper sheds light on the problem of resource optimization using Linear Programming approach. The mathematical formulation considers various parameters like Associate's availability (hours), Historical Performance (Items processed per hour), Service Level Agreement (SLA) of work-mix in its formulation. The optimization-based solution is implemented in a typical back-office processing unit in a financial organization.


Periphyton communities are considered as solar-powered biogeochemical reactors and are assemblages of algae, heterotrophic microbes and prokaryotes. The diversity and species composition of epidendric periphyton from the submerged roots of a Cocos nucifera which was fringing on Paravur Lake was qualitatively and quantitatively estimated. The study site is a sheltered area in the lake which is bordered with patches of mangroves. Sampling was done during a period of February to June, 2016. Physico-chemical parameters of water like Temperature, Salinity, Turbidity, Biological Oxygen Demand, Dissolved Oxygen, Acidity and Alkalinity were estimated. Soil Texture and Soil pH were also assessed. 66 species of microalgae under 29 genera were collected and identified from coconut roots. Class Bacillariophyceae (86.38%) dominated among microalgae. Other representative classes were Coscinodiscophyceae (3.03%), Zygnematophyceae (4.54%), Cyanophyceae (4.54%) and Euglenophyceae (1.51%). Apart from microalgae, some faunal groups like Bivalves, Barnacles, Crustaceans, Crustacean larvae and Polychaete worms were also identified from the coconut root. Roots of coconut tree seem to be a reservoir of periphyton with great diversity which is somewhat comparable to mangrove pnuematophores which abode large number of periphyton. Variations in the physico-chemical parameters of water and soil, and the diversity and number of periphyton are revealed. Based on the results, the ecological role of epidendric periphyton on the coconut tree root is discussed in detail. (Key words: Periphyton, Coconut Roots, Backwater, Paravur Lake, Kerala)

The possible linkage of ENSO and IOD to JJAS rainfall variability over Ethiopia []

Rainfall is the most important climate element for rainfed agriculture and the general socio-economic development of Ethiopia. This study examined the possible linkage of ENSO and IOD to the rainfall of June to September (JJAS) over Ethiopia during 1991-2020. The correlation coefficients show that JJAS rainfall has closest relationship with nino3.4 and DMI indices on September and January respectively, and those are much greater with the nino3.4 indices. And the anomalous lower pressure systems, strong convective activity with convergent flows and water fluxes are helpful for the formation of positive JJAS rainfall, and vice versa. The regression analysis of the JJAS rainfall and the tropical forcing denotes that there is close linkage of the SSTA and the induced vertical motion over eastern Pacific to the JJAS rainfall over the country. Further study suggests that the warm/cold SSTA over eastern Pacific can induce anomalous ascending/descending vertical motion with an opposite one coupled over the area from Indian ocean to the Africa, which will enhance/suppress the high pressure, and the convective activities over the study region will be suppressed/enhanced, and hence cause the reduction/increase of rainfall over Ethiopia. The result of this study will help to improve the seasonal rainfall prediction and early warning of extreme rainfall events over Ethiopia.

Spatiotemporal Trends of Lassa Fever Surveillance in North Easthern States, Nigeria. []

Abstract Lassa fever is a viral haemorrhagic fever transmitted by rats. Lassa fever is a longstanding public health concern in West Africa with recent molecular studies confirming the fundamental role of the rodent host (Mastomys natalensis) in driving human infections, but control and prevention efforts remain hampered by a limited baseline understanding of the disease’s true incidence, geographical distribution and underlying drivers. We analyzed confirmed reported data from surveillance records of NCDC dashboard between 2015 to 2020 and primary health facilities from ehealth Africa for spatiotemporal trends of lassa fever and distribution of primary health facilities for upgrade to a diagnostic center. The results shows a spatiotemporal trends increase with hot spot at Bauchi (127), Taraba (117), Gombe (12), Adamawa (5), Borno (4) and Yobe (0) confirmed cases despite a clustered distribution of primary health centers and the population of people in the study area with increment from 2015-2020, there is no LF diagnostic center in the study area. From this report, challenges to control efforts which included poor local laboratory capacity, inadequate/poor quality of protective materials, fear among health workers, and inadequate emergency preparedness should be put in place for proper health planning. Key words: Lassa fever, Northeastern, Nigeria, Spatiotemporal, Surveillance.

The Research Teaching of Inquiries, Investigations, and Immersions: Basis for a Unified Research Paper Format []

The study was conducted to determine the efficiency of technical writing rules and guidelines set forth by the curriculum in providing student researchers with adequate assessment, correction, and revision that help in writing a better output. It aims to propose a unified research format where the department and the division can adapt. Survey research was used as the fundamental model of research. The quantitative method was then used to treat data that utilized estimates of the parameter through statistics. Among the one hundred (100) respondents, thirty-six (36) are male students, and six (6) male teachers, a total of forty-two (42) male respondents and forty-four (44) female students, and fourteen (14) female teachers, a total of fifty-eight (58) female respondents. The study showed that the teacher enables students to identify research pitfalls on his own through guided evaluation, however, it shows that the adviser’s ability to showcase pros and cons whenever a researcher decides on matters pertinent to research accomplishment is lack lustered. Following this, the evaluation of both the student and teacher respondents showed that revisions made in the research-related literature and studies showed the most favorable results, while the revisions made for research methods showed the least favorable results. The research has determined that outlines are a general necessity that aids the researcher in gathering thoughts and including pertinent details to the paper. Along with this are the capabilities of teachers to be well-versed in all aspects of technical research.

Drug repurposing for the treatment of Type 2 Diabetes and Gestational Diabetes Mellitus []

Currently, repurposing an existing medicine for treatment of a different disease is a good and lucrative choice because of the long and time-consuming research and development process of new drugs and the high attrition rate. The utilization of low-risk chemicals, lower overall research costs, and shorter development timelines are all contributing to its growth and appeal. Ideal repurposed medication candidates have been found using a variety of date- and experimental-driven methodologies. However, there are a number of technological and legislative issues that must be addressed. Type 2 and gestational diabetes mellitus are both forms of diabetes mellitus, although gestational diabetes mellitus is a transitory condition that can lead to type 2 diabetes in the future. About 90% to 95% of diabetic people have type 2 diabetes, which is the most common form of the disease. Currently medications used for the treatment of these two diabetes is basically Metformin which often regarded as first line of treatment for Diabetes, but it is not affective too much and just control the condition. In order to identify a more effective therapy for Type 2 diabetes and gestational diabetes, we are going to use the Drug repurposing approach to look at novel pharmaceuticals and treatments and alternative combinations of current drugs. Medicine repurposing strategies and their usage in the search for a better drug or combination of drugs for the treatment of Type 2 Diabetes and Gestational Diabetes have been addressed in this review article.

Impact of COVID-19 on food processing and supply chain []

Coronavirus disease 2019 (COVID-19) is a clinical condition caused by the coronavirus-2, which causes extreme acute respiratory syndrome (SARS-CoV-2). The World Health Organization (WHO) declared COVID-19 a pandemic on March 11, 2020, due to its rapid spread across many countries, as well as its high mortality rate among the elderly and infirm. Pandemics are known for their devastating effect on the global economy. COVID-19 has been observed to have an impact on the entire process in food processing and supply chain (from the field to the consumer) which is one of the most important sectors of the economy. Workers' movement constraints, changes in market demand, the closing of food processing facilities, limited food trade policies, and financial strains in the food supply chain were all consequences of COVID-19. There is now considerable concern regarding food production, manufacturing, distribution, and demand. To avoid a rise in food prices, food protectionist policies should be avoided, governments should make it easier for workers and agricultural products to move around. By modifying safety measures, facilities should improve working conditions while also protecting employees' health and safety. Cleaning, sanitation, good hygiene practices, and active packaging are also required from farm to consumer. The goal of this review is to assess the impact of COVID-19 on agriculture and food production, as well as to summarize the recommendations needed to mitigate and control the pandemic's impact.

Deep freezers are considered to be an important household item that falls under the category of cooling appliances. The basic structure of the freezer consists of a thermally insulated compartment which through a proper mechanism lowers down the temperature inside it and transfers the heat from inside to the external environment. As it keeps the temperature lower so it is used to keep and store the food items which can be spoiled at ambient temperature. Deep freezers in all the sizes are available at the market but they are restricted and limited for indoor usage only as they require electricity and are large. But presently, people are more inclined towards outdoor activities and they need to have a freezer to keep the essential items saved from spoilage and wastage. Therefore this study is geared towards the designing a mobile deep freezer that is powered through the batteries and is portable which can be easily used outdoors as well carried about. Consequently, the design was fabricated using locally made materials. This is to encourage local ingenuity and to reduce cost of production comparable to already made and foreign deep freezers. It is designed to be simple, handy and readily available to be used by anyone in case of malfunctioning and for easy relocation. Though, the main limitation of the system fabricated is the long time it uses to achieve cooling and finally the machine is affordable to all, and is highly recommended for local entrepreneurs for mass production because of its cost effectiveness, simplicity and availability of spare parts.

Inhibitive effect of Grapefruit peels on Titanium steel in acidic solutions []

The corrosion inhibitive effect of Citrus × Paradisi (CP) (grapefruit) inhibitor, has been experimented on Ti steel samples in 0.5 M HCl and 0.25 M H2SO4 solutions by weight loss method and open circuit potential. Result revealed that the presence of active components in Citrus × Paradisi inhibitor supported the inhibitive nature and its potency by mitigating corrosion effect on the Ti steel samples in both acidic solutions. The corrosion rate values decreased drastically for all the steel samples as both CP inhibitor and inhibitor efficiency increases. The highest inhibitor efficiency (IE) occurred in HCl solution with 91% at the maximum CP inhibitor concentration. Also, the open circult potential shows that CP inhibitor performed like a mixed type of inhibitor. This confirms excellent adsorption behaviour of CP inhibitor on the Ti steel samples.

The importance of Buddhist moral education for moral education in the family in Ho Chi Minh City today []

Buddhist ethics has affirmed its profound influence on the lives of Vietnamese people. Buddhism is one of the important cultural resources of the Vietnamese nation (along with Taoism and Confucianism), has been creating history with it, and at the same time has become a condition for promoting the values of Buddhism. nation in the present situation. Relating to Buddhism as a path to spiritual and moral upliftment, the authors analyze the value-based factors of Buddhist ethics and moral education in the family in Ho Chi Minh City today. The author reveals the particularity of Buddhism’s ethics, including the fact that the teaching does not aim to distinguish right from wrong by connecting morality to a set of metaphysical dogmas to then reflect on. In essence, Buddhism is existential, but its humanism is non-metaphysical, as it is based on the concept of nirvana rather than theistic absolutism. On the one hand, Buddhism acknowledges scientifically sound standards; on the other hand, it emphasizes the moral and existential aspects of modern Vietnamese life. Such a combination today is truly relevant and in line with today’s social development goals.

Factors that influence the uptake of IPTp in pregnancy at the Redemption Hospital (September 2021) []

This thesis used a quantitative approach to investigate factors influencing uptake of intermittent preventative treatment of malaria in pregnancy at the Redemption Hospital (September 2021). The target sample for the study was 250 pregnant women attending ANC at the Redemption Hospital. Closed-ended structured questionnaires were used to collect the information from women who attended clinic on the days the research was conducted (convenience sampling). The results of study found that majority of participants (n=207, 82.8%) were knowledgeable on the prevention of malaria during pregnancy. The unavailability of SP was shown to be an issue at Redemption Hospital. Furthermore, most participants said that they carry or buy their own water when they come to the clinic in order to take the SP that is given them. Additionally, attitudes of healthcare workers towards pregnant women were found to be good. Majority of the pregnant women (n=208, 83.2%) indicated that healthcare workers have not acted rude on them during their ANC visits. Accordingly, to enhance transparency and accountability, the study recommends that the conduct of bi-monthly training sessions for health workers as a way of building their capacity for delivering health education; a regular monitoring and evaluation of IPT services must also be stressed to guarantee continuous availability of drugs, clean water and clean cups for proper IPT management. The Redemption Hospital should adapt best practices from other government and private run Hospitals and budget for provision of safe and clean water. The benefits of SP should be taught during ANC health education sections to guarantee that antenatal women know the correct number of doses that are required of them. Moreover, an external monitoring Team should be set-up to check on the administration of SP.


The coronavirus pandemic has brought about deep and unprecedented transformations in the world economy and population, and industries have suffered various impacts in different areas. Given this scenario, the way of working had to adapt to avoid an increase in the number of absences from work and the consequent drop in productivity. Absen-teeism is a phenomenon that originates from extrinsic and intrinsic fac-tors and is quite expensive for organizations. To this end, 188 employ-ees who work in three different shifts in a 24 hour period participated in the study. For statistical analysis, the correlation coefficient of R was used. The loss of productivity between the periods from 2019 to 2021 was (1%) through the adjusted R², yet the loss of productive hours in the same period was (8%). The results indicate that there was a weak relationship between absenteeism associated with a drop in productivity in the period of the Covid-19 pandemic

By applying Fast Fourier Transform technique with operation, the fault detection instruments give correct fault result with saving the time.

Improve the Performance of AODV-SOS and FORP-SOS Routing Protocols in MANET for Emergency Rescue Services Based on Obtained Signal Intensity []

Finding the specific paths between the source and destination nodes in MANET routing protocols is necessary. During a natural calamity, when our regular communication network is disrupted for the damage to the ground station, at that time, AODV-SOS and FORP-SOS rout-ing protocols in MANET are expected as an alternative medium for communication. Such as, when a victim wants help at a time of calami-ty and contact cannot be established at that time, it is difficult for the victim to communicate with the rescue team if the IP address is not known. Our goal is to fix the issue. We have considered FORP-SOS and AODV-SOS, which constructed S-O-S packets without endpoint addresses in MANET routing protocol FORP and AODV, and figured out their connection strength. This paper aims to enhance the resili-ence of FORP-SOS and AODV-SOS routing protocols in MANET based on obtained signal intensity to remove S-O-S packets when the accepted signal intensity is lower than a predetermined threshold at each time node accepts an S-O-S packet. Finally, we test our en-hanced technique on a network simulator and determine its performance through extensive simulations.
