    The paper examines the alternative sources of revenue or resource mobilisation from internally generated revenue (IGR), statutory allocation and utilisation for sustainable development to the university management. The study employs descriptive survey design (mean and standard deviation) and Pearson Product Moment Correlation. The results revealed that business ventures owned by university management are among the main sources of revenue, the proceeds include servicing staff welfare, maintenance of university facilities and remodelling of university environment. The finding revealed that there is no significant relationship between revenue generated in university and the development. The paper therefore recommended that, government should support all universities with funding to strengthening revenue base usefulness

    Background: Effective wastewater treatments are paramount to modern-day Scientists. The available methods are ineffective in detoxifying tannery wastewater. Aim: This study synthesize and characterized polysiloxane-Immobilized thiosalicylic-mercaptoethanol ligand system (PITSMCBLS) and used in detoxification of Cr3+ and Fe3+ from tannery wastewater.Method: Porous solid PITSMCBLS was prepared by hydrolytic polycondensation of tetraethylorthosilicate with mixture of 3-chloropropyltrimethoxysilane, methanol and sodium hydroxide as catalyst. The gelation formed (3-CPP) after 40 min, was functionalized (F-3CPP) with excess ethylchloroacetate, triethylamine and grafted with thiosalicylic-mercaptoethanol bi-ligand. The PITSMCBLS was characterized using FTIR and SEM-EDX. The competitive sorption characteristics of metal ions (Cr3+ and Fe3+) were studied using Microwave Plasma Atomic-Emission Spectrophotometer.Result: The FTIR spectrum of PITSMCBLS showed vibrational frequencies (cm-1) at: 3339, (O-H); 2928, (C-H); 2685, (SH); 2497, (Si-H); 1587–1707, (C=O) and 1028, (Si-O). The SEM-EDX showed irregular particle sizes (4.4294 ± 1.7187 nm) and elemental composition (wt %): 3-CPP, Si (50.45); O (25.02) and Cl (24.57). The F-3CPP showed, O (58.68) and Si (41.32), while PITSMCBLS showed 11.94 of S. Gibbs free energy yielded negative range values for ΔGo (Cr3+ -14.187 to -14.832 and Fe3+ - 14.369 to -14.843 kJmol-1), positive values for: ΔHo (Cr3+ 5.345 and Fe3+ 0.000 kJmol-1) and ΔSo (Cr3+ 64.459 and Fe3+ 47.421 Jmol1K1) respectively.Conclusion: PITSMCBLS exhibits high potential for extraction of Cr3+ and Fe3+ in tannery wastewater. The Thermodynamic values indicate spontaneous, endothermic reactions and high degree of disorderliness with respect to metal ion binding capacity to the ligand system. This development would improve tannery wastewater treatment.</div

    External validation of the PROLOGUE score to predict neurological outcome in adult patients after cardiac arrest: a prospective cohort study

    No full text
    Abstract Background The PROLOGUE score (PROgnostication using LOGistic regression model for Unselected adult cardiac arrest patients in the Early stages) is a novel prognostic model for the prediction of neurological outcome after cardiac arrest, which showed exceptional performance in the internal validation. The aim of this study is to validate the PROLOGUE score in an independent cohort of unselected adult cardiac arrest patients and to compare it to the thoroughly validated Out-of-Hospital Cardiac Arrest (OHCA) and Cardiac Arrest Hospital Prognosis (CAHP) scores. Methods This study included consecutive adult cardiac arrest patients admitted to the intensive care unit (ICU) of a Swiss tertiary teaching hospital between October 2012 and July 2022. The primary endpoint was poor neurological outcome at hospital discharge, defined as a Cerebral Performance Category (CPC) score of 3 to 5 including death. Results Of 687 patients included in the analysis, 321 (46.7%) survived to hospital discharge with good neurological outcome, 68 (9.9%) survived with poor neurological outcome and 298 (43.4%) died. The PROLOGUE score showed an area under the receiver operating characteristic curve (AUROC) of 0.83 (95% CI 0.80 to 0.86) and good calibration for the prediction of the primary outcome. The OHCA and CAHP score showed similar performance (AUROC 0.83 and 0.84 respectively), the differences between the three scores were not significant (p = 0.495). In a subgroup analysis, the PROLOGUE score performed equally in out-of-hospital and in-hospital cardiac arrest patients whereas the OHCA and CAHP score performed significantly better in OHCA patients. Conclusion The PROLOGUE score showed good prognostic accuracy for the early prediction of neurological outcome in adult cardiac arrest survivors in our cohort and might support early goals-of-care discussions in the ICU.

    Factors associated with the risk of malaria among children: analysis of 2021 Nigeria Malaria Indicator Survey

    Abstract Background Malaria remains a burden globally, with the African region accounting for 94% of the overall disease burden and deaths in 2019. It is the major cause of morbidity and mortality among children in Nigeria. Though different environmental factors have been assessed to influence the distribution and transmission of malaria vectors, there is a shortage of information on how they may influence malaria transmission among under-fives in Nigeria. Methods This study was based on the secondary data analysis of the Nigeria Malaria Indicator Survey 2021. The study sample comprised 10,645 women (aged 15–49) who delivered a child in the 2 years preceding the survey. The study was restricted to under-fives. Logistic regression was used to identify factors associated with the risk of malaria. Results There was a positive association between the risk of malaria and heard/seen malaria messages in the last 6 months (AOR 1.39, 95% CI 1.19–1.62), houses with walls built using rudimentary materials (AOR = 1.38, 95% CI 1.04–1.83), at least 6 children living in the house (AOR 1.22, 95% CI 1.00–1.49), children being 1 or 2 years old was associated with increased odds (AOR 1.89, 95% CI 1.50–2.34 and AOR 1.89, 95% CI 1.52–2.36), children from households with only treated nets (AOR 1.23, 95% CI 1.04–1.46) and those from the North West or South East regions (AOR 1.50, 95% CI 1.10–2.05 and AOR 1.48, 95% CI 1.01–2.16), respectively. All other predictors were not associated with the risk of malaria. Conclusion The factors associated with the risk of malaria in this study included sleeping under treated mosquito nets, the age of the children, residing in the northwest and southeast regions, wall construction material, 6 children and above in the household and hearing/seen malaria messages in the last 6 months. Continuous health education and public health interventions, such as the provision of LLITNs, will reduce the risk of malaria and improve the health and well-being of children under 5 years of age

    Uptake, distribution in different tissues, and genotoxicity of imidacloprid in the freshwater fish Australoheros facetus

    The neonicotinoid imidacloprid is under re-evaluation by regulatory agencies because of the poor current information available regarding its potential effects. One of the goals of the present study was to determine imidacloprid uptake and distribution in the freshwater fish Australoheros facetus experimentally exposed for 24 h and 48 h to 100 μg/L, 300 μg/L, and 2500 μg/L. The toxicity of imidacloprid to fish reported in the literature is in the milligrams per liter or gram per liter range, but sublethal effects at micrograms per liter in some groups other than fish have been described. Another goal of the present study was to evaluate imidacloprid's potential genotoxicity and to compare it between the individual compound and a commercial formulation. Concentrations of imidacloprid were measured in water, brain, muscle, gills, gut, liver, and blood by liquid chromatography-tandem mass spectrometry. Imidacloprid was detected in all the tissues tested. Concentrations were higher after 48 h than after 24 h in liver, gills, gut, and muscle, whereas in brain and blood they were similar at both exposure times. Although there was no accumulation, only uptake, of imidacloprid, genotoxicity was observed. In fish exposed to IMIDA NOVA 35®, increased micronucleus frequency at 100 µg/L and 1000 µg/L was detected, whereas in the imidacloprid active ingredient bioassay it increased only at 1000 µg/L imidacloprid. The present findings warn of the possible consequences that fish living in freshwater ecosystems can suffer. Environ Toxicol Chem 2017;36:699–708. © 2016 SETAC.Fil: Iturburu, Fernando Gastón.
