Remediation potentials of composite metal-organic frameworks (MOFs) for dyes as water contaminants: A comprehensive review of recent literatures

Abstract: In wastewater treatment, metal–organic frameworks (MOFs) have indeed attracted much attention in recent years as effective adsorbents and/or photocatalysts for removing or degrading organic contaminants such as dyes. A limitation of MOFs during remediation is the leaching of metal ions and ligand into solution, which further contaminates water. Therefore, in recent times, researchers have adopted and worked on the use of composing materials such as graphene oxide, activated carbon, Ag/AgCl, magnetic particles and so on as doping agents to enhance the structural stability, photocatalytic and adsorptive properties, and separability of MOFs. Consequently, this paper aims at reviewing published research articles in recent times on the synthesis and applications of MOF composites. In addition, the mechanisms of MOF degradation in water, the methods for preparing MOF composites, influence of operating parameters such as pH of the aqueous media, initial contaminant concentration, and adsorbent/photocatalyst dosage on the adsorption/photodegradation processes are discussed. Most of the results observed revealed that the composites were highly efficient for wastewater treatment, and at fast rates.

Microbial valorization of corncob: Novel route for biotechnological products for sustainable bioeconomy

Abstract: Huge amount of renewable biomass in excess of 140 billion metric tons is generated annually due to agro-industrial activities. The agrowastes are often disposed indiscriminately or burnt off, thereby constituting environmental menace and contribute to global warming through the generation of greenhouse gases. Most frequently, the biomasses despite their richness in nutrients are also not found suitable for deserving applications. Among the agrowastes, generation of corncob occupies a prime position due to large scale cultivation of maize worldwide, as more than 200 million tons of corncobs are produced yearly. In recent times, to achieve environmental sustainability, value-addition to wastes, and promotion of advances in bio- and circular economy, agrowastes are now being investigated for valorization through biotechnological route. The preponderance of microbes with their concomitant production of different varieties of degradative enzymes makes them suitable for bioconversion of agrowastes to viable bioproducts in eco-friendly manner. The valorization of agrowastes is in direct responses to achieving five of the goals of SDG; particularly good health and wellbeing (SDG 3), clean water and sanitation (SDG 6), affordable and clean energy (SDG 7), industry and innovation (SDG 9), and climate action (SDG 13). In this review, we present recent activities on biotechnological valorization of corncob to create new range of bio- and nanoproducts to stimulate more research endeavours in this area.

Metabolic syndrome and occupation: Any association? Prevalence among auto technicians and school teachers in South West Nigeria.

Abstract: Aims To determine occupational association with metabolic syndrome among auto technicians and school teachers. Methods One hundred and sixty six subjects were selected for this study. Clinical data was obtained while laboratory investigations including plasma glucose and lipid profile were performed. Statistical analysis was done with SPSS 20.0. P Results School teachers had significantly higher mean total cholesterol and LDL-cholesterol compared to auto technicians. Mean serum triglycerides was significantly higher among auto-technicians compared to school teachers in this study. The prevalence of some conventional cardiovascular risk factors was significantly higher among auto-technicians compared to school teachers: Impaired blood glucose (9.6% vs. 1.2%, p Conclusion The prevalence of metabolic syndrome appears to be significantly higher among auto technicians despite their high level of physical activity, exertion and education compared to teachers. This may be related to the increased occupational exposure to organic and inorganic materials from dust particles, oil and oil related matter and particulate matter among auto technicians. Prompt definitive evaluation of this concept and appropriate health education to encourage safety mechanism can reduce this burden of metabolic syndrome among auto technicians in Nigeria.

Prediction of compressive strength of oil field class G cement slurry using factorial design

Abstract: Proper slurry design is critical to the success of a cementing job. The best method to obtain a good slurry design with desired compressive strength is by laboratory experiments which involve experimenting different formulations and selecting the best composition for the specific cementing operation. This exercise is not only time consuming considering the amount of time required, but also expensive. Sixteen sets of experiments were conducted in the laboratory, and factorial design was used to design the experiments for the sensitivity analysis of four different factors impacting on the compressive strength of cement slurry. The responses from the 16 experimental runs were used to develop a model which can be used for optimization purposes. The model developed was simple, in agreement with the experimental data used and can be implemented using an ordinary simple calculator.

An autopsy review of sudden unexpected natural deaths in a suburban Nigerian population

Abstract: The pattern of diseases causing sudden unexpected natural deaths is a function of the prevalent disease pattern in the general population. This pattern appears to be changing in Nigeria in response to changing demographics and lifestyle. This was a descriptive retrospective autopsy-based review of cases of sudden unexpected natural deaths seen at the Obafemi Awolowo University Teaching Hospitals Complex in Ile-Ife, Nigeria (OAUTHC) over a 10-year period. Analysis was done for differences in proportion using Chi square (p is significant at <0.05) by SPSS version 15. Sudden unexpected natural deaths accounted for 13.4% of all medico-legal autopsies. The male to female ratio was 2.1:1, and the mean age was 43.1 years ± 19.5 SD. Cardiovascular (28.3%), respiratory (18.2%), and central nervous system (12.6%) disorders were the major groups of causes. About 64.4% of cardiovascular deaths were due to hypertensive heart disease. Bacterial pneumonia, intracerebral haemorrhage, and breast carcinoma accounted for 34.4%, 60.0%, and 52.6% of respiratory, central nervous system, and cancer-related deaths respectively. Infectious causes predominated in all age groups below 40 years and above 70 years while hypertensive disorders predominated between 40 and 70 years. Only 16.9% of cases occurred while the patient was admitted to the hospital. Cardiovascular, respiratory, central nervous system, and cancer-related causes were the major causes of sudden unexpected natural deaths in our series. Hypertension-related disorders constituted a large proportion of cases especially in people over 40 years, whereas infectious diseases were more common below this age. The majority of deaths occurred outside the hospital setting. It is imperative that appropriate public health strategies be developed to address these issues.
