The CWL characteristics were studied using Fourier Transform Infra-Red (FTIR) spectroscopy, Scanning Electron microscopy (SEM) and point of zero charge (PZC) to establish surface functional groups present, morphology and net neutral charge of the adsorbent. The effects of contact time (15-150min), dosage (20-200mg), initial concentration (20-140ppm), and pH (3-13) on the adsorption process were investigated for the removal of MG by batch adsorption method. The result shows that all the parameters have effect on adsorption process. Compared to the Langmuir, Freundlich, Temkin, and D-R models, the isotherm models were investigated and confirmed to fit well onto the D-R model. Pseudo-second order model best fitted the kinetic data for the different operating temperature (300C, 400C, 500C) of the analysis. Thermodynamics studies clearly indicates that the sorption was spontaneous, endothermic, and increased in the randomness of the systems at adsorbent-liquid interfaces as a result of negative Gibb’s free energy (∆G), positive enthalpy (∆H) and Entropy (∆S). Therefore, this study confirmed that carbonized water lily leaves adsorbent could be used as an alternative adsorbent for the adsorption of toxic dyes such as Malachite green dye.","PeriodicalId":235595,"journal":{"name":"UMYU Scientifica","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115627358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, 4 ml of blood was collected from HIV+ patient who has not commenced antiretroviral treatment. PBMCs were isolated using the Ficoll-Paque method and counted using the trypan blue assay. The isolated PBMCs were treated with different concentrations of the PHF (25 50, 100, and 200 μg/ml). Cytotoxicity and proliferation were determined using the WST-8 assay. The percentage viability in this study was 96.74%, whereas the non-viable cell percentage was 3.26%. The lowest percentage of cytotoxicity for the PHF was 0.05% at 25 µg/ml of the extract, while the highest was 5.35% at 200 µg/ml. The mean absorbance scores of the formulation's various concentrations and the control group did not significantly differ from one another (F=0.622, df = 5, p=0.69). There was significant difference (t= -4.887, df =6, 95% CI= -0.1566 to -0.0521, p = 0.003) in mean absorbance scores between control and treatment. The polyherbal formulation exerts the lowest cytotoxicity of 0.05% and significant proliferation on the PBMCs at 25 µg/ml.

Plate technique was used to isolate soil fungi and morphological identification was through macro and microscopy. Koch’s postulate was followed in the assessment of pathogenicity of the identified organisms on the three sorghum germplasms (Yelai, Kaura and Warwarbashi). The isolated fungal species were found to be Aspergillus niger, Aspergillus flavus, Rhizopus stolonifer, Mucor spp and penicillium spp. Pathogens with highest occurrence observed was A. niger , R. stolonifer and Penicillium spp with 30, 25 and 20% occurrence respectively. Thus, all the three cultivars of S. bicolor screened were very susceptible to the tested pathogens, with A. niger and R. stolonifer found to be highly virulent.

In this regard, the impact of various experimental parameters namely, contact time, adsorbent dose, initial dye concentration, pH, and temperature were assessed and optimized. The adsorbent was characterized using Fourier transformed infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), and point of zero charge (PZC) analysis. The maximum adsorption rates of ARS and EBT onto UTG were determined to be 49.92 mg/g and 47.43 mg/g, respectively, at equilibrium. In comparison to previous models evaluated, removal of both ARS and EBT by the UTG demonstrated that the data had a strong fit with pseudo-second-order kinetic and Freundlich adsorption isotherms. The contact time for both dyes was optimised at 15 minutes, while the pH for ARS and EBT were attained at 8 and 2 respectively. However, based on the established results of various parameters in this study, the adsorptive removal of ARS and EBT by UTG was a favourable process. The Van't Hoff plot was used to calculate the thermodynamic quantities of the adsorption process, including ΔG, ΔH and ΔS. The outcomes showed that the process was both spontaneous and thermodynamically possible. From the parameters tested, EBT was found to be better adsorbed onto UTG than ARS. Even though both dyes are anionic in nature, but EBT has additional diazo and nitro functional groups than the hydroxyl and sulphate functional groups present in ARS. This might be the reason for the better adsorption of EBT onto UTG than ARS. Results from this investigation supported the efficiency of UTG as a low-cost and environmentally friendly solution for the adsorption of ARS and EBT from contaminated wastewater.","PeriodicalId":235595,"journal":{"name":"UMYU Scientifica","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122339108","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These models often lead to special class of ordinary differential equations known as stiff ODEs. A system is regarded as ‘stiff’; if the existing explicit numerical methods fail to efficiently integrate it, or when the step size is determined by the requirements of its stability, rather than the accurateness. The solution of stiff ODEs contains a component with both slowly and rapidly decaying rates due to a large difference in the time scale exhibited by the system. The stiffness property prevents the conventional explicit method from handling the problem efficiently. This nature of stiff ODEs has led to considerable research efforts in developing many implicit mathematical methods. This paper discussed the convergence and order of the current variable step size super-class of block backward differentiation formula (BBDF) for solving stiff initial value problems. The necessary conditions for the convergence of the fourth order variable step size super class of BBDF for solving stiff initial value problems, has been established in this work. It has been shown that the new method is both zero-stable and consistent, which are the requirements for the convergence of any numerical method. The order of the method is also derived to be four. It is therefore concluded that the method is convergent and has significance in solving more complex stiff initial value problems, and could be robustly applied in many fields of study.","PeriodicalId":235595,"journal":{"name":"UMYU Scientifica","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129654711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, not much information is available on their micronutrient status of soil of the Jos Plateau. Hence, the objective of this study was to assess plant available Cu, Zn, Mn and B in soils derived from migmatite, granite gneiss and biotite granite parent materials on the Jos Plateau. Seven profile pits were dug in each geologic unit and soil samples obtained using guidelines in the soil survey manual. Available Cu, Zn, and Mn in soil samples were determined using the 0.1 M HCl extraction method and data collected was subjected to one-way analysis of variance. The results indicated that there were significantly higher contents of available Cu in the A horizon for soil derived from migmatite than in those over biotite granite or granite gneiss. Mean available Cu contents in the A horizon were 1.61 (± 0.35), 1.7125 (± 0.96), and 3.33 mg/kg (± 0.16) for granite gneiss, biotite granite and migmatite respectively; whereas for the B horizon mean contents were 2.06 (± 0.40), 2.98 (± 1.31), and 4.13 mg/kg (± 1.93) for granite gneiss, biotite granite and migmatite respectively. Generally, there were no significant differences in distribution of Mn, Zn and B among the geologic units. Implying that soils derived from migmatite, granite gneiss and biotite granite seems to behave similarly in contents of available Cu, Mn, Zn and B.
