Attitude towards wearing face mask increases vulnerability of men over women and the risk of covid-19 pandemic spread in jos-south metropolis, plateau state, nigeria

Background Covid-19 pandemic has hit many countries and put the majority of the public health system to test globally. Mandatory use of face mask was among policies set by the government to contain the spread of the novel disease. But citizens’ attitudes and compliance with these policies are important in controlling the pandemic. We assessed gender-based compliance to Covid-19 protocol (use of face mask) in Jos South, Plateau State, Nigeria. Methods Perception regarding Covid-19 and the use of face masks were assessed among participants using a questionnaire-based survey. In a cross-sectional study, ninety (n=90) questionnaires were administered to willing participants directly. A Chi-square test was used to determine the descriptive analysis of all responses, P-values <0.05 were considered statistically significant. Result Out of 90 participants, 55.6% (50/90) were male and 44.4%(40/90) were female. Forty-two (84%) males deny the existence of the pandemic while in females, 14 (35%) deny that Covid-19 exist. Thirty-seven (74%) of the male respondents do not comply with to use of the face mask and use a single face mask multiple times without decontamination. In females, 28 (70%) comply with the use of the face mask. Unlike the men, 20 (50%) of the females always decontaminate the face mask. The middle-aged adult (26-45 years) uses the face mask more than the young (18-25 years). There was a significant association of gender in relation to the perception of Covid-19 and the use of facemask (p< 0.05). Conclusion Male respondents showed an irresponsible attitude complying to Covid-19 protocol than the females, therefore, enlisting them as a risk factor for the continued spread of the virus. We recommend that public health awareness and campaigns should focus and employ greater influence on men and young adults in their compliance with the preventive protocols.

Public perception and behavior on the disposal of unused and expired drugs

Evidence demonstrates that inappropriate drug disposal creates a significant risk to global environmental safety. Study participants' knowledge, attitude and practice regarding the disposal of unwanted and expired medications were assessed. The study was carried out at Sebha city, in southwestern Libya, from October 2021 to April 2022. A self-administered questionnaire designed explicitly to be completed by a respondent without an interviewer's assistance was used. Out of 650, only 500 completed questionnaires was returned. The majority of the respondents admitted they have at least one medication stored at home (71.6%). Keeping expired drugs were reported by 28.2% of the respondents compared with unused medications in their house (51.2%). Almost half of the respondents (47.4%) declared that their medication were taking from the private pharmacies. “I’ll need it in the future” (48.8%), "Medicines change" (37.2%) and "Symptoms improve and recover" (32.6%) were the top three explanations given by participants. The majority of drugs reported were antibiotics (41.0%). This is followed by antipyretic and analgesic drugs, which were used by 29.8% and 27.8% of respondents, respectively. 52.2% of the respondents agreed that disposing of medicines in the garbage is the most appropriate method. Concordantly, the majority of them indicated they discarded unused or expired medicines whether they were solid (82.6%), liquid (58.4%), or semisolid (79.6%). The majority of participants indicated they were aware of the negative impact of drug waste on the environment (80.6%). More than three quarters of the participants said they had never been given instructions on how to properly dispose of medications and 60.8% thought a medical team would be the best source of knowledge. Despite acknowledging being aware of the harmful effects on the environment, the majority of participants admitted to keeping unneeded pharmaceuticals in their homes and throwing them out in the trash. The government should support the pharmacists' role in educating the public about how to properly dispose of their medications and establish the Return Unwanted Medicines Project in order to raise awareness and create cost-effective medication waste management programs.

Ru-dye grafted cus and reduced graphene oxide (cus/rgo)composite:an efficient and photo tunable electrode for dye sensitized solar cells

The CuS@reduced graphene oxide (CuS/RGO) hybrid nanocomposite was synthesized by facile hydrothermal method and used as a photoelectrode material in photovoltaic applications. In the hydrothermal route, RGO is formed by the reduction of GO with simultaneous formation of CuS/RGO nanocomposites. The CuS/RGO nanocomposites was investigated using powder XRD, TEM, HR-TEM, Raman, XPS, DRS UV–Vis spectroscopy, Photoluminescence (PL) measurements. XRD and TEM results suggest that CuS crystalline with individual spherical like homogeneous nanoparticles sizes in the range of 45–35 nm, which is distributed throughout the RGO sheets. We further construct the flexible photoelectrodes by using CuS and RGO and studied the photovoltaic performance. Photovoltaic parameters, such as short-circuit photocurrent density, open circuit voltage, fill factor and conversion efficiency were found to be 16 mA/cm2 , 0.71 V, 70.1% and 7.81% respectively, for CuS/RGO photoelectrode. The improved photo conversion efficiency of CuS/RGO is due to enhancing the electronic injection ability and reducing the photogenerated charge recombination. These photovoltaic results indicate a simple methodology for the low cost and effortless synthesis of an alternative CuS/RGO photoelectrode in high performance photovoltaic devices.

Preferred learning techniques among bachelor’s level students

Learning styles describe how individuals acquire, interpret, and assimilate knowledge differently. The effective use of learning styles is essential for effective classroom education. The three most popular learning styles are kinaesthetic, auditory, and visual. This study pursued to learn more about the preferred learning modes of college students. There were 152 respondents from Baneshwor Multiple Campus, Kathmandu Nepal. The data were collected from first year students of BBS, B.Ed. and BA. The researchers used a scale of learning styles (VAK) with 28 items to accomplish the study's goal, and after confirming its validity and reliability, it was applied to the sample. The results show that there are no statistically significant differences in the types of learning patterns preferred by students. Based on these findings, the study recommends that teachers are encouraged to diversify college teaching strategies and methods to suit the preferred learning styles of their students, particularly new students, in order to motivate them to learn in the college environment and to provide the training needs and requirements necessary to enable them to take individual differences among their students into account when identifying educational goals.

A challenging presentation of pyrexia and macroscopic hematuria in a kidney transplant patient

Kidney transplant kidney transplant ( KTx) recipients have increased susceptibility to a spectrum of infections including; bacterial, viral, and fungal pathogens. Many factors contribute to their infection potential risk, in terms of their immunosuppressive state, that result in suppression of their B‑and T‑lymphocyte repertoire, also to consider certain donor and recipient‑related factors, that make them at risk of specific type of infectious complications. In addition kidney transplant patients tolerate poorly infections, which may adversely affect their graft function, by inducing glomerular injury, hence early diagnosis, directed therapy, and careful dosing of antimicrobial agents is of paramount importance in reducing patient’s morbidity and mortality. We report a kidney transplant patient, who received her live related kidney graft 7 years earlier (in 2013), she has been with stable graft function in most of her follow up period, until she presented with pyrexia, dyspnea and fatigue associated with deterioration of her graft function.

Exploration of drug-drug interaction in prescriptions of libyan practitioners in community pharmacies

The drug-drug interactions (DDIs) are actions or events that occur when two or more drugs administered together, may cause a clinical significance or not. There are certain factors that may affect the severity of DDIs such as age, gender, number of drugs prescribed, and physician specialists. This study aims to answer: Is there DDI in Libyan community pharmacies? In addition, to explore the factors that might be affecting DDI. Drug Interactions Checkers are used. 200 prescriptions were collected randomly from two different areas ( high and low income),100 from each one and were used to investigate the DDIs by using two different sources (Drugs.com and BNF platforms), bearing in mind, age, gender, prescribers’ specialty, and drug number (prescription size). A personal interview questionnaire with pharmacists for investigate a source of DDI knowledge was considered. The correlation test was used to analysis the findings. The randomly selected sample has 316 drug combinations. The study has revealed a minimum of three drugs (46.0%). In general, Drugs.com was the richer source of DDI than BNF (66.5% and 34.5%, respectively). It is found that 66.5% (67.0% of this is moderate DDI) of these combinations have DDI by Drugs.com. A significant correlation between DDI and gender (male > female, p = 0.035) was found. In a state of residential areas, the results are similar in both selected pharmacies. Most moderate DDIs (21.0% and 15.0%) are prescribed by orthopedics and psychiatrists, respectively. The observational interview questionnaire indicated that 100% of the participating pharmacists had no source of knowledge regarding DDI, 100% of 200 prescriptions had no chick it regarding DDI and 100% of found DDI is released to use by community pharmacies to patients. More than half of the prescribed drug combinations have DDIs (classified as moderate DDIs), and all of them are released for use by pharmacists.

What really matters: experiences of emergency remote teaching in university teaching and learning during the covid-19 pandemic

The COVID-19 pandemic and related lock downs have accelerated the need for online and remote teaching within university settings. However, due to the abrupt nature of the pandemic, many academic staff were not prepared for this forced transition. This study aimed to understand how the pandemic affected academics at a New Zealand university, with regards to their transition to emergency remote teaching. Specifically, it explores the challenges as well as benefits academics experienced during this transition. Recommendations for future online learning are also made. Academic staff (N 67) at a New Zealand University completed an anonymous online survey. Quantitative data were analyzed statistically using descriptive and inferential statistics, while qualitative data were analyzed thematically. Major challenges experienced included miscommunication from the university, concerns about student access to technology, finding a quiet space to work, lack of digital competence skills, too much screen-time, managing work hours, and work/ life balance. Benefits included enhanced flexibility, enhanced teacher creativity, increasing autonomy of learners, and reduced commute time. Looking forward, academic staff desired future teaching to include blended learning and virtual immersion. New strategies of working remotely are being explored to facilitate teaching and learning while catering to the preferences and skills of both educators and students. Our findings honor the considerable agility of academic staff who sought to sustain and enhance excellence in remote education. At an institutional level our findings point to the need for staff to be supported by their institutions as they further refine their work within new-found spaces

Relationship between culture and gender inequality in india

This paper throws light on the role played by culture and traditions specifically of Hindu religion in legitimising the subordinate position of women in Indian society. Along with presenting a brief account on the status of women from ancient times to contemporary situation, the sex-gender binary has also been explored. How a child after his birth socialised to behave in a certain way on the basis of his/her sex has been noted. This process of socialisation is based on the age old customs and traditions which are discriminatory in nature. The male child is taught to be strong, dominating and aggressive in nature and henceforth assigned laborious work to do for managing the finances of house. On the other hand, female child is taught to be sensitive, loving and caring and therefore assigned to manage household work, child nurturing and motherhood related responsibilities.

Accounting for managers

Financial accounting can be viewed as the process through which businesses record, summarize, and report their business transactions over a specified time (Yu, Lin, and Tang, 2018). Financial accounting aims to keep track of all business transactions that the business has engaged in over a specified time. Financial accounting also provides a snapshot of the financial health of the business entity. Financial accounting is crucial due to various factors. First, financial accounting ensures that proper financial statements are preferred in line with accepted accounting standards (Mita et al., 2018). Secondly, financial accounting ensures that the managers make crucial financial decisions in line with the financial statements. Financial accounting is also carried out to ensure that a business complies with the set taxation laws. Financial accounting is also crucial when valuing the business for significant events like merging and sale of the business (Homburg, Theel, and Hohenberg, 2020). Financial accounting can also provide evidence in case of legal suit and also provides crucial information to external and internal users of financial information.

Intersection of caste and gender based subjugation

One of the unique features of Indian society is prevalence of caste system which was originated thousands of years back to demarcate the people engaged in different occupation or jobs. Initially it was not much rigid but gradually people belonging to upper castes for their own selfish means to maintain their monopoly made this arrangement hereditary and started treating people of lower castes disgracefully. For preservation of this system, people started controlling their women to prevent inter-caste marriages and the concept of endogamy came up. This robbed away many types of freedom from women. For women belonging to lower castes, this situation is worse as they are doubly subjugated on the basis on caste as well as gender. Men belonging to their own caste treat them as secondary beings. This paper throws light on this intersection. How intersection of these two kinds of inequalities place them at the lowest position in Indian society. Dr. B.R. Ambedkar rises as their leader who all his life worked for empowerment of downtrodden section of society. He argues that education is the primary tool for evading these differences among people. He further emphasizes to adopt the concept of exogamy to break the backbone of Indian caste system and to immediately leave a religion or culture which legitimizes such system of inequality among people of the same land.

Comparison of broiler performance under two rearing systems (floor vs cages).

Abstract: This study was conducted on two groups of broiler , the first consists of 4 replicates of 10 birds and the second of 10 birds as each bird is a replicate in individual cages. The first group were reared on floor during the entire period ,while the second was reared in cages during the period from 2-7 weeks of age. All birds received the same ration with 2859 Kcal/ kg ME and 22% CP as a starter ration, 2995 Kcal/kg ME and 19.19% CP as a finisher ration. The results showed that cage birds had a significantly (P≤0.01) higher body weight , total and daily weight gain at all ages , significantly(P≤0.01) higher total and daily feed and protein consumption , at 2- 4 , 0-4 weeks , feed and protein conversion ratio at 4- 7, 0- 7 weeks. Also cage birds showed a significantly better growth rate at 2- 4 , 0- 7 weeks and less dressing percentage, higher wing percentage while other carcass parts did not differ significantly. The cage birds showed better economic efficiency by 27% comparing to floor birds.

Coping up with covid-19 in india: a new way of surviving indian hospitality industry

India's hotel and hospitality industry occupancy decreased significantly in the first quarter of 2020, as the outbreak of COVID-19 affects different segments of the market. The outbreak of the novel coronavirus (COVID-19) has inflicted a blow on industries around the world, but maybe none as devastating as hospitality and travel. Depending on the length of the pandemic, companies across the industry adjusted growth forecasts for 2020, estimated profits to be conservatively 40-50 percent lower than expected before the outbreak. The effect on hospitality demand is greater than many other sectors, but even among hotels, air and cruise ships, and restaurants it is varied. Hotels and airlines operate at half capacity, with both business and leisure travelers canceling scheduled trips and not arranging any for the near future.The present article aims to study some novel practices for the survival of hospitality industries once the lockdown is over.

An application of modified path matrix approach for detection of isomorphism among epicyclic gear trains

The identification of isomorphism in epicyclic gear trains has been found a lot of attention by researchers for the last few years. Various methods have been suggested by different authors for the detection of isomorphism in planer kinematic chains and epicyclic gear trains (EGTs), but everyone has found some difficulties to address new issues. In this paper, a modified path matrix approach was presented in order to compare all the distinct geared kinematic mechanisms. A new method based on the matrix approach and corresponding train values is required to identify isomorphism among epicyclic gear trains and their mechanisms. The proposed method was examined on the basis of various examples from four-link, five-link, six links, and eight-link one-degree-of-freedom EGTs and six links two-degree-of-freedom EGTs. All the examples have been found satisfactory results with existing literature.
