Authors: Hasanah Kanzulia Arysta Qaribil , Mulyono Resha Dwi Ayu Pangesti , Fiqkri Mohammad
Published: January 2023

Sumberlesung Village is a village that is administratively located in Ledokombo District, Jember Regency. One of the most famous potentials of Sumberlesung Village and continues to be developed is the handicraft industry in the form of beads, which are exported abroad. But in reality, even though it has been exported to various countries, it turns out that the existence of this beading craft is still not well known by the local community and needs to be expanded further abroad. So that there is a need for improvement and development in terms of segmentation and marketing locally and abroad, this happens because the bead artisans in Sumberlesung Village have not yet marketed their products digitally so an innovation is needed that can integrate their products with technology. Departing from the above problems, the author plans an idea in the form of village empowerment by establishing a community in Sumberlesung Village equipped with software, namely ERP (Enterprise Resource Planning) which is integrated with the website. The research method used is qualitative research with a A.D.D.I.E. The expected target of this research is that the bead craftsmen are members of a community who can market digitally in export and import activities as well as the craftsmen who understand the concept of technology and ERP software systems.

Multiple Sclerosis Associated with a Broad Repertoire of T Cell Receptors That Are Specific to Epstein-Barr Virus
Authors: Donelan Nicola
Published: January 2023

Is infection with the Epstein-Barr virus the long-debated cause of multiple sclerosis? A new study has now added to the mounting evidence supporting this hypothesis: it analyzed the T cell receptor β-chain repertoires of 1,395 MS patients and found more TCRβ sequences specific to the virus in MS patients than in healthy individuals. These findings are consistent with the hypothesis that MS is associated with an ongoing immune response to the Epstein-Barr virus that goes awry, leading to central nervous system damage. They also seem to be independent of differences in genetics or early environmental factors.

MULTIVARIATE APPROACHES TO CLUB LARGE WATER QUALITY DATA FROM AQUATIC TOXICITY STUDIES: A REVIEW STUDY
Authors: KAUR RAJBIR , DUA ANISH , KAUR SATINDER
Published: January 2023

Water is the most valuable, widespread resource, major constituent of all living creatures and extremely essential for the sustenance & existence of life. This is exemplified by its multiple uses such as drinking, cooking, washing, irrigation, farming, industrial activities and many more. Quality of surface waters are getting deteriorated as water resources are polluted due to the discharge of industrial effluents, agricultural run-off having insecticides, pesticides, heavy metals, fertilizers, chemicals, sewage and other domestic wastes. This review strongly recommends the incorporation of regular monitoring programmes for reliable estimation of water quality, effective pollution control and water resource management. The practice of conducting physicochemical studies is even essential/mandatory before conducting any toxicity study using fishes or any other sentinel organism both for in-vivo and in-vitro studies. Frequent sampling at many sites with a lot of water quality parameters generates a large & complex data matrix that needs data interpretation. The use of different multivariate approaches provide a rapid solution by identifications of factors that are mainly influencing water quality, clustering many parameters to identify the parameters mainly responsible for spatial and temporal variations linked to seasonality. In this way, reliable management of water resources as well as rapid solutions to pollution problems and effective environmental impact assessment can be approached.

Authors: Orewere Emmamoge , Owonubi Ayodele
Published: January 2023

Parent materials play significant roles in determining the resultant characteristics of various soils. 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. Also, soil particle size had a significant moderate relationship with Cu and may influence its distribution in these soils.

Published: January 2023

Fish feeds (Fish bolsters) are produced in form of flakes, pellets, or tablets designed to contain vegetables, proteins, cereals, vitamins, and minerals fundamental for ideal development and wellbeing of fishes. However, the scientific evaluation of the feeds compositions as claimed by most manufacturers is lacking in many parts within Nigeria.   Proximate composition analyses were carried out in some selected fish feeds marketed within the Kano metropolis following the method of the Association of Official Analytical Chemists. The result of the proximate investigation showed the following composition: 7.28-11.16% ash, 6.10-12.26% moisture, 11.13-14.29% lipid, 3.01-5.61 % fibre, 37.45-44.30% protein and 20.26-27.70% carbohydrate. There was no critical distinction (p>0.05) noticed among the values of all the proximate compositions of the fish feeds studied. However, a few values exceeded the permissible limit, whereas the majority fell within limits set by relevant regulatory agencies. Considering that most of the feeds were within the permissible limit of regulatory bodies, it could be deduced that the fish feeds are safe for fish consumption.

Published: January 2023

Soil borne pathogens appears to be one of the most devastating groups affecting S. bicolor causing wide range of pre-harvest and post-harvest diseases, plant diseases are commonly managed through different strategies, the use of resistant varieties found to be more economical and ecofriendly. This poses the need to screen different varieties of S. bicolor for horizontal resistance of some fungal species commonly found in the soil. 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. It was concluded that, all the varieties showed a continuous minute or absence of horizontal resistance against the isolated pathogens which could be responsible for post-harvest diseases in Sorghum germplasm.
Convergence of the Fourth Order Variable Step Size Super Class of Block Backward Differentiation Formula for Solving Stiff Initial Value Problems
Authors: Bala Najamuddeen  , Musa Hamisu
Published: January 2023

In many fields of study such as science and engineering, various real life problems are created as mathematical models before they are solved. 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.

The instability of Premium Motor Spirit (PMS/Petrol) and other energy commodities prices, occasioned by volatile and dynamic movement of prices has been found to affect the cost of production in Nigeria. As a result, this paper studies current literature on the applications of machine learning techniques in forecasting PMS (Petrol) and other energy commodities prices. The review has been done through an electronic search of the published papers in the last 4 years (2019-2022). A total number of twenty-nine (29) publications on PMS (Petrol) and other energy commodities prices forecasting using machine learning models were selected for the study to identify research gaps and future works. This paper covers a summary of reviewed published papers on forecasting PMS (Petrol) and other energy commodities prices using machine learning techniques, semantic analysis of algorithms used, and the taxonomy of the models adopted in the published papers. The results showed that there are studies that presented the application of machine learning models in forecasting the prices of PMS (Petrol) and other energy commodities in other countries. However, very few of them have proposed the construction of machine learning models for forecasting PMS (Petrol) and other energy commodities prices in Nigeria. This leads to the need to develop new models, especially deep learning hybrid models.

Cowpea damage caused by pest infestation is a major challenge to farmers and traders in Nigeria which request urgent response. This research is aimed primarily to evaluate the proximate composition and degree of infestation effect on cowpea (Vigna unguiculata L. Walp) nutrients. The samples of cowpea were randomly collected in the Lapai market, refrigerated for a week to stop insect action and were separated into two categories, non-infestation (sample without exit hole) and infestation (samples with one, two and three exit holes), Samples were subjected to proximate composition and statistical analyses for variation in nutrient. Results show a rise in protein and moisture content in the sample without infestation. But shows a decrease in Carbohydrate, Fat, Fibre and Ash content in non-infested samples. For the infested sample, infestation leads to significant deterioration of nutrients of food products developed from cowpeas. The current result shows that pest infestations reduced nutritional benefits as a protein source in livestock and human diets.

Keeping track of students’ lecture attendance is important as it provides the basis for enforcing the policy of having prerequisite minimum attendance to qualify for examinations. It is equally important to the parents/guardian of the students as they will be in the know of whether or not their wards have been attending lectures or not.  However, taking accurate records of student attendance manually can be tedious. Similarly, deploying attendance machines can be costly. To this end, this paper proposes designing and implementing a token-based attendance management system as an affordable and alternative approach to managing students’ attendance. In the new system, a lecturer simply counts the number of students present in a lecture session and hands them tokens. The students use the tokens to mark their presence.  The system was implemented using Hypertext Markup Language, Twitter Bootstrap, JavaScript, Hypertext Preprocessor, and MySQL. The system was deployed and put to use at Al-Qalam University Katsina. The implication of practice is that the software can be replicated, deployed and used in any academic institution.

A twelve month study was carried out between March 2020 and February 2021, to assess water quality parameters and fishermen catch per unit effort of Zobe reservoir in Katsina State, Nigeria with the aim of understanding the contamination position of water body and fishing effort. Five chosen sampling stations are; Raddawa, Tabobi, Gada, Garhi, and Makera. Selected physicochemical parameters such as temperature, pH, NH3, turbidity, alkalinity, BOD and alkalinity were assessed using standard methods. However, they were within all the recommended level for optimum performance of tropical fish species. Individual fishermen catch was used throughout the study period, where each of the five (5) Landing sites was visited twice monthly for catch assessment survey. Fish samples were randomly collected from 5 canoes/fishermen per sampling unit and catches were observed and recorded. There was high catch in the month of July and August (wet season) for all the species in Zobe reservoir. In contrary, there was strong negative correlation between temperature and DO; pH and DO; turbidity and DO; DO and BOD; DO and alkalinity. Makera had higher catches than any of the other stations with more than 700 bi-weekly catch representations between the months of July and August, 2020. Dry season CPUE was up to 22% for wet season and 9.80% for Clarias gariepinus in Garhi fishing station which recorded the highest, whilst for Clarias anguilaris CPUE recorded absolute zeros for all the stations and for both seasons except for Makera in wet season with 0.08% CPUE. Physicochemical parameters of Zobe reservoir showed that the water quality of Zobe reservoir changes with season, however, the parameters were within an acceptable range for fish growth and dependency of fish catch and water quality was observed.

This study analysed households fuelwood consumption as domestic cooking energy source and the implications on the environment in Vandeikya Local Government Area of Benue State, Nigeria. A total of two hundred and forty (240) respondents were selected using multistage sampling procedure to elicit information for the study. Primary data for the study was garnered with the use of structured questionnaires and interview schedule and was analysed using descriptive and inferential statistics. Findings from the study revealed that the majority (81%) of the household heads were males with a mean age of 40 years. 83% of the respondents were married and had at least one form of education with secondary education having the highest share of 49%. The average household size of the respondents was 7 persons with majority (52%) of them taken to farming as their main occupation The mean monthly income of the respondents was N43,150. Majority (79%) of the respondents use firewood as their main fuel source for cooking which they obtained mostly at no cost from the forests (44%) and their farmlands (37%). The average cost price of a bundle of firewood stood at N200 in the study area while that of kerosene is N750/litre in the study area.  Charcoal is sold at N2500/50kg bag (N50/kg), electricity, N61.5/kwh and gas, N780/kg. The average consumption level of fuelwood by respondents was estimated at 3 bundles daily. The result reveals that lack of cheaper energy alternatives (88%), large family sizes (84%), easy availability (77%) were the main reasons given by the respondents for fuelwood consumption over other sources. The perceived environmental effects of fuelwood utilization were; deforestation (75%), global warming (57%), Indoor and outdoor pollution (53%), and violent windstorms (46%), among others. Marital status, educational status, household size, monthly income and cost of Gas significantly influenced the consumption of fuelwood by households. The study recommends use of alternative and clean energy sources should be encouraged and the corresponding alternative energy technologies made available and affordable to residents to reduce the overreliance of households on the use of traditional energy carriers such as firewood and charcoal, thereby reducing their negative impact on health and environmental degradation. Tree planting campaigns should be embarked upon by both residents and relevant authorities to replenish the depleted forest resources and for their sustainability.

Layer production depends on many factors, and it is an excellent source of nutritious animal protein (meat and eggs). Empirical knowledge of the determinants of firm efficiency improves productivity in poultry-egg production systems. Therefore, this study analysed firm efficiency and return to scale in layer production among smallholders in Jos-North, Plateau State, Nigeria. Primary data collected via two-stage cluster sampling were evaluated using descriptive statistics, regression, and elasticity of production analysis. The results revealed that average flock size, feed quantity per cycle, medication cost, labour and capital requirement was 105 birds, 2,750kg, N 17,250, 1095 person-days and ₦330,750, respectively. The coefficient of determination (R2) is 0.768, indicating that variables in the regression model explain 77% of the variation in layer production. Moreover, the coefficient of variables including flock size (-0.446), feed quantity (0.791), medication cost (0.165), labour (0.275) and capital (-0.131) were significant determinants of layer production. The estimate of return to scale was 0.654(ρ<1), indicating decreasing returns. In addition, the major constraints of layer production include the high cost of feeds (91.3%), inadequate capital (80%), disease outbreaks (70.8%) and high medication and equipment costs (61.3%).  This study recommends improved input supply and subsidies; access to farm capital, commodity markets and farm cooperatives; adoption of modern technology, practices and provision of technical support to enhance firm efficiency and optimize productivity.

Like humanity and civilization itself, the idea of beauty and cosmetics is very old. Beauty is a major obsession among women. They therefore utilize a variety of cosmetics to keep their skin glowing. Elderly women and traditional medicine practitioners (TMP) are increasingly experimenting/using herbs, trees, and shrubs to determine their efficacy for beauty and dermatological care as the demand for plant-based cosmetics rises. The study was aimed at survey of plants and recipes from used by females in Katsina City, of the Northwestern Nigeria. Using a semi-structured questionnaire, 15 (TMP) and 20 Traditional Cosmetic businesses spread over 15 different areas of the city were interviewed between November 2021 and August 2022. The survey resulted in the documentation of seventeen (17) plant species representing fourteen (14) distinct families and seventeen (17) recipes. The most often utilized plants were found to be Lawsonia inermis, Curcuma longa and Allium cepa with a frequency of 12.5, 8.5 and 8% respectively. Tomato and meant leaves each with 2% frequency, were found to be the least frequently used ingredients in recipes. Due to the plants' demonstrated efficacy, as stated by the respondents, adequate recording, conservation, cultivation, and use of these cosmetic plants are required in order to prevent their extinction or threatened status.

Published: January 2023

The aim of the research is to assess the viability of castor (Ricinus communis) and senna (Senna occidentalis) plants up to 90 days after planting (DAP) in agricultural soil spiked with different concentration of zinc in the screen house. Agricultural soil was collected from Bayero University Kano, at 11° 98ʹ 32.59″N; 8°42ʹ 43.97″E. Soil texture, pH, electrical conductivity (EC), organic carbon (OC), nitrogen (N), phosphorus (P) and exchangeable cations (K + , Ca + , Mg + and Na + ) were determined. Castor and senna were planted in soil spiked with 2 mg/kg, 4mg/kg and 8 mg/kg of zinc sulphate (ZnSO4) each. Control plants containing only  agricultural soil without spiking with zinc  were added and the set up replicated 4 times. Plant height, number of leaves and root length were assessed at 45 and 90 days after planting (DAP). The soil was sandy loam, slightly acidic, C, N, P and K+ had mean values of 0.41%, 0.33 mg/kg, 14.33 mg/kg and 0.39 cmol/kg respectively. There were significantly higher (p<0.05) mean values for height (16.85cm) and root length (17.35 cm) of control castor plants than those treated with zinc at 45 DAP.  At the termination of the experiment (90 DAP), senna plants in control had significantly higher mean values for height (29.5 cm) than all other treatments.  All concentrations of zinc used in this work did not seem to have much negative effects on the vegetative growth of both test plants.

The most prevalent type of mycorrhiza are arbuscular mycorrhizal fungi (AMF). in plants and have been used as biofertilizer due to its ability to capture and supply water and nutrients to plants. In this study, investigations were carried out to ascertain the effect of biofertilizer (AMF), organic (cow dung) and inorganic fertilizers (NPK) on chlorophyll and moisture contents of pearl millet crop. Experiments were conducted in greenhouse and treatments arranged in a Complete Randomized Block Design. The treatments were replicated four times each and monitored for chlorophyll concentration and shoot moisture contents as it affects crop yield. The chlorophyll a concentration varied from 0.92 mg/g to 1.18 mg/g, while the plants treated with NPK fertilizer exhibited highest chlorophyll a (1.18 mg/g). It was followed by the control (1.15mg/g) and organic manure. The plants inoculated with biofertilizer had the infinitesimal chlorophyll a (0.92mg/g). However, for chlorophyll b, plants treated with biofertilizer (1.01mg/g), organic manure (1.09mg/g) and NPK (1.26mg/g) exhibited higher content than in control plants that had the lowest (0.53mg/g) value. Statistics revealed that there was no discernible difference. (P<0.05) between leaves chlorophyll contents in plants treated with organic manure and NPK fertilizer. Millet treated with organic manure, biofertilizer and the control did not significantly (P<0.05) differ from one another with respect to shoot moisture contents. Although NPK had more chlorophyll contents, biofertilizer promoted more grain yield (2030 grains /m2) than all the treatments. Findings from this study indicated that biofertilizer can alternatively be used for better yield when organic and inorganic fertilizers are costly and unaffordable to peasant farmers. Further studies on biofertilizer are recommended to provide effective formulations for improved crop growth and better yield.
