Reactivating Nigerian norms and values through religious studies for national transformation

Reactivating Nigerian norms and values are essential ingredients in the transformation of the nation, because it is a missing link that is breeding moral decadence in the society. Therefore religious education which inculcates good moral values such as honesty, fidelity to one’s duty, love for one’s neighbour and self-discipline should be given a prominent position in the schools. Moral decadence is a pervasive evil that poses great challenge to Nigerians. It is also a national problem with certain destructive tendencies, hence the need for the entrenchment of moral values to salvage the nation from decay. Societal norms and values play important roles in the social lives of individuals and society at large. This is because they deal with values, behaviours and attitudes exhibited and encouraged by members of the society. Thus Religious Education is essential for activating Nigerian moral values in order to infuse sanity into the fast decaying Nigerian’s value system. Morality is an integral part of societal progress and transformation. It is also the life wire of any successful society. In fact a society that is experiencing moral decadence is not only being inactive but indeed sick. The knowledge gotten from religious education will enable one to conform to the societal norms and values, so that he will not be a social deviant. This paper therefore examines the concept of reactivating Nigerian norms and values through religious education for national transformation. A number of recommendations are made which include the inclusion of religious education at all levels of Education and students should be taught the Nigerian norms and values and encourage them to conform to it to avoid being sanctioned or labeled social deviants

Comparison of the electrochemical performances of MCDCFC using hand and ball milled biomass carbon fuels

The electrochemical performances of a single cell molten carbonate electrolyte direct carbon fuel cell (MCDCFC) using miscanthus and switchgrass biomass carbon fuels subjected to hand and ball milling treatments are presented in this paper. Conventional direct carbon fuel cell (DCFC) uses carbon derived from coal, a fossil fuel with adverse consequences on the environment. This paper explores a more benign carbon fuel source which is the biomass to power the DCFC. The performances of the hand milled (HM) carbon fuels were slightly higher than those of the ball milled (BM) carbon fuels. At 800oC for the open circuit voltage, miscanthus fuel (1.03 V) has higher values for the HM and switchgrass fuel (0.77 V) for the BM. Higher peak power densities were observed for switchgrass fuel (21.60 and 12.32 mW/cm2) for both the HM and BM. Switchgrass fuel (74 mA/cm2) gave the maximum current density for both the HM and BM. Miscanthus fuel (0.72 V) show higher voltage at peak power generation for the HM and switchgrass fuel (0.39 V) for the BM. The peak power efficiency evaluated show that miscanthus fuel (70%) gave higher values for the hand milled and equal values for both carbon fuels (51%) for the ball milled

Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study

Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.

Reading tea leaves worldwide: decoupled drivers of initial litter decomposition mass‐loss rate and stabilization

The breakdown of plant material fuels soil functioning and biodiversity. Currently, process understanding of global decomposition patterns and the drivers of such patterns are hampered by the lack of coherent large‐scale datasets. We buried 36,000 individual litterbags (tea bags) worldwide and found an overall negative correlation between initial mass‐loss rates and stabilization factors of plant‐derived carbon, using the Tea Bag Index (TBI). The stabilization factor quantifies the degree to which easy‐to‐degrade components accumulate during early‐stage decomposition (e.g. by environmental limitations). However, agriculture and an interaction between moisture and temperature led to a decoupling between initial mass‐loss rates and stabilization, notably in colder locations. Using TBI improved mass‐loss estimates of natural litter compared to models that ignored stabilization. Ignoring the transformation of dead plant material to more recalcitrant substances during early‐stage decomposition, and the environmental control of this transformation, could overestimate carbon losses during early decomposition in carbon cycle models

Studies on characterization of solid fuel using municipal solid waste from Bida, Nigeria

Municipal solid waste (MSW) in Bida, Nigeria consists of domestic waste with the addition of commercial waste. Disposal of this wastes constitute environmental problem in Bida and Nigeria in general. Selected amounts of MSW were considered in this study which are dried grass, melon peels, paper, sugarcane bagasse and saw dust. These materials were carbonized at 350 degree Celsius and the solid carbon fuel obtained were analyzed using particle size, x-ray diffraction (XRD) and scanning electron microscopy (SEM). The particle size measurement showed that dried grass has percentage intensity using dynamic light scattering at Z-average (135.2 nm), polydispersity index (0.453) and duration of 60 s. The mineralogical properties observed from XRD analysis showed that minerals like calcite, graphite, quartz, magnesium and gypsum were present. The peaks indicated at 2θ were within the range of 21 degree Celsius - 58.5 degree Celsius. Out of these, 21 degree Celsius was for sugar cane bagasse in crystal area and 58.5 degree Celsius for saw dust in amorphous area. The morphological properties revealed rough surface, hollow structure, homogeneous particle and irregularity. The particle size, mineralogical and morphological properties indicated that the solid carbon produced can be applied in direct carbon fuel cell, cement industry, iron and steel industry. The proper application of these solid carbon fuels can reduce environmental problems associated with MSW disposal in Nigeria

Digestive Manifestations in Patients Hospitalized With Coronavirus Disease 2019

This article is made available for unrestricted research re-use and secondary analysis in any form or by any means with acknowledgement of the original source. These permissions are granted for the duration of the World Health Organization (WHO) declaration of COVID-19 as a global pandemic.BACKGROUND & AIMS: The prevalence and significance of digestive manifestations in coronavirus disease 2019 (COVID-19) remain uncertain. We aimed to assess the prevalence, spectrum, severity, and significance of digestive manifestations in patients hospitalized with COVID-19. METHODS: Consecutive patients hospitalized with COVID-19 were identified across a geographically diverse alliance of medical centers in North America. Data pertaining to baseline characteristics, symptomatology, laboratory assessment, imaging, and endoscopic findings from the time of symptom onset until discharge or death were abstracted manually from electronic health records to characterize the prevalence, spectrum, and severity of digestive manifestations. Regression analyses were performed to evaluate the association between digestive manifestations and severe outcomes related to COVID-19. RESULTS: A total of 1992 patients across 36 centers met eligibility criteria and were included. Overall, 53% of patients experienced at least 1 gastrointestinal symptom at any time during their illness, most commonly diarrhea (34%), nausea (27%), vomiting (16%), and abdominal pain (11%). In 74% of cases, gastrointestinal symptoms were judged to be mild. In total, 35% of patients developed an abnormal alanine aminotransferase or total bilirubin level; these were increased to less than 5 times the upper limit of normal in 77% of cases. After adjusting for potential confounders, the presence of gastrointestinal symptoms at any time (odds ratio, 0.93; 95% CI, 0.76-1.15) or liver test abnormalities on admission (odds ratio, 1.31; 95% CI, 0.80-2.12) were not associated independently with mechanical ventilation or death. CONCLUSIONS: Among patients hospitalized with COVID-19, gastrointestinal symptoms and liver test abnormalities were common, but the majority were mild and their presence was not associated with a more severe clinical course
