The aim of the study was to determine the facial  morphometry of the Mwaghavul ethnic group of Plateau State, Nigeria. The objectives were to determine facial dimensions, facial index  and facial types of Mwaghavul ethnic group. Four hundred and five (405) participants (231, males; 174, females) aged 18-30 years were  involved in this study. The study was carried out on Mwaghavul students of College of Education Gindiri, Mangu LGA of Plateau State in  Nigeria. The photographic setup consisted of a tripod stand and digital camera. The participants were positioned at a distance of 120 cm  from the camera. The camera was raised to the ear level of the participants to provide good quality of image and to prevent distortion of  the face. The photographs were captured at a standard resolution of 12.1 megapixels. A digital vernier caliper was then used to measure  the facial linear dimensions. The photographic records were analysed using a bioanalyser (version 6). The program was customized with  the landmarks used in this study.

Many factors can contribute to adverse drug reactions, including  genetics and drug targeting/delivery. Genetic markers, such as single nucleotide polymorphisms (SNPs) in drug-metabolizing enzymes,  drug targets, and human leukocyte antigen (HLA) genotypes, have been associated with an increased risk of ADRs. Pharmacogenomics is  the study of the genetic variation in the way that different people react to different pharmaceuticals, including variations in the risk of  adverse drug reactions, dose requirements, and efficacy. The implementation of genetic data for predicting responses to medications  and ADRs is becoming a reality in clinical practice, offering the potential to reduce the incidence of ADRs and improve patient outcomes.  As pharmacogenomic research continues to advance, it holds great promise for enhancing drug safety and efficacy, ultimately leading to  more tailored and effective therapeutic interventions. ","PeriodicalId":479620,"journal":{"name":"Dutse Journal of Pure and Applied Sciences","volume":"55 20","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140662651","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}

Random soil samples were taken from a solid dumpsite and its adjacent closed bottomland at depths  of 0–15, 15–30, and 30–75 cm and analyzed in the laboratory. Soil texture, soil moisture content (MC), porosity, bulk density, pH, electrical  conductivity (EC), organic carbon (OC), potassium (K), calcium (Ca), magnesium (Mg), and sodium (Na) were measured. Also examined  was the concentration of heavy metals such as lead (Pb), cadmium (Cd), arsenic (As), nickel (Ni), chromium (Cr), and manganese (Mn) in  the samples. Soil moisture content (MC), porosity, bulk density, pH, and electrical conductivity (EC) ranged from 8.52 to 16.08%, 30.14 to  51.19%, 1.16 to 1.46 g/cm3, 6.98 to 7.58, and 299.82 to 432.61 μS/cm, respectively. The concentrations of nutrients and heavy metals (OC,  K, Ca, Mg, and Na) and (Pb, Cd, As, Ni, Cr, and Mn) in the soil samples collected from the solid waste dumpsite and bottomland ranged respectively from 2.13–3.10%,, 3.98–6.57, 5.08–8.11, 5.41–7.11, and 0.98–2.61 Cmol/kg, and 6.83– 29.04, 0.00–0.35, 0.41–3.92, 0.89–3.46,  0.00–0.63, and 13.74–74.38 mg/kg. The highest concentrations of nutrients and heavy metals were found in the soil sample collected from  the solid waste dumpsite between 0 and 15 cm of soil depth, and it was closely followed by the sample obtained from the bottomland at the same soil depth compared to other locations. The concentration of heavy metals did not exceed the limits established  by the World Health Organization (WHO) and the Food and Agricultural Organization (FAO), but persistent dumping of waste in the area  may eventually increase the concentration of heavy metals beyond the acceptable limit. There is a need for the locals to be aware that the  growing of crops on dumpsites and closed adjacent bottomland due to its fertility status could result in the uptake of heavy metals  and eventually end up in human or animal bodies. A measure to avoid dumping waste close to the bottomland should be put in place by  ensuring the immediate construction of a standard environmental sanitary dumpsite in combination with the waste recycling strategy in  the study area. ","PeriodicalId":479620,"journal":{"name":"Dutse Journal of Pure and Applied Sciences","volume":"99 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140659228","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}

The intermittent nature of the DC side of these systems can significantly impact their  performance. However, the extent of this impact remains uncertain when employing the stationary reference frame PLL (αβPLL)  algorithm for synchronization with the utility grid. Employing simulation in MATLAB 2020a and a Model Based Design approach in the  Simscape toolbox of SIMULINK, we conducted this investigation through two test scenarios: one with constant solar irradiance and  varying temperature, and the other with varying solar irradiance and constant temperature. Our results indicate that fluctuations in solar  irradiance and temperature have minimal effects on the output parameters of grid-connected PV systems when synchronized with the  stationary reference frame PLL (αβPLL) algorithm. This conclusion is supported by the total harmonic distortion values, which all fall  within the specified limits of IEEE Standard 929- 2000. These findings underscore the potential of αßPLL synchronization as a promising  technique, capable of effectively synchronizing grid inverters even in the presence of DC input distortion. This proficiency in grid  integration holds promise for enhancing the integration of renewable energy sources into the grid, thereby bolstering power availability  for household distribution. ","PeriodicalId":479620,"journal":{"name":"Dutse Journal of Pure and Applied Sciences","volume":"48 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140662164","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}

Comparative analysis of these minerals and proximate composition will  showcase their health and nutritional benefits. This study aimed to compare the proximate composition of Z. spina christi and P. biglobosa fruits. The proximate analysis shows that some parameters (ash, crude fiber and moisture content) were significantly (p<0.05)  higher in the fruit of P. biglobosa when compared to Zizipus spina christi fruit [(5.76±0.17 % and 3.15±0.12 %), (12.35±0.46 % and  5.59±0.16 %), (3.16±0.05 % and 1.99±0.02 %) respectively], while other parameters such as crude protein, crude fat and carbohydrate  content were significantly (p<0.05) higher in the fruit of Z. spina christi when compared to P. biglobosa fruit [(13.23±0.60 % and 11.09±0.60  %), (75.80±0.10 % and 67.53± 0.09 %), (0.14±0.01 % and 0.13± 0.01 %) respectively]. Also, the mineral composition were also  analyzed; potassium (250.72± 0.03 mg/kg), magnesium (47.04± 0.04 mg/kg), iron (12.77± 1.02 mg/kg), manganese (2.26± 0.55 mg/kg) and  sulfur (1.92± 0.12 mg/kg) were found to be significantly (p<0.05) higher in the fruit of P. biglobosa when compared to Zizipus spina  christi fruit, while calcium (177.72± 0.07 mg/kg), zinc (2.53± 0.08 mg/kg) and phosphorus (10.85± 0.13 mg/kg) were found to be significantly (p<0.05) higher in the fruit of Zizipus spina christi when compared to P. biglobosa fruit. The present study showed that the  fruits of both trees contains important mineral and proximate composition; therefore, they could be utilized as raw materials in food and  pharmaceutical industries.             ","PeriodicalId":479620,"journal":{"name":"Dutse Journal of Pure and Applied Sciences","volume":"96 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140659242","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}
