Published: July 2023

There is global progress toward gender equality with 68% of the countries in the World Economic Forum Gender Gap Report of 2019. Despite the progress, education and income are among areas in which gender is still not equally enabled in developing regions. As the world is progressing in reaching gender-equal access to education and income some programs appeared in gender equity to wipe out some obstacles faced by girls and women in education and income which may invariably improve the socio-economic status. The quantitative- exploratory-Correlational design was used in a gender-disaggregated form on the parents with children in the Reggio Emilia Early Childhood Development (REA-ECD) centres. The sample size of 405 with 204 females and 201 males was used through multistage-systematic random sampling. The instrument for data collection was adapted, data collection with the aids of trained enumerators and analysed in descriptive and binary logistic regression. The results show a significant improve (44.9%) with tertiary education, mean income N34,572. 840, [USD138.291]and 28.5 times (odds=29.46) more likelihood of high REA-ECD acceptance for girls and boys to attend schools. These revealed the need for more programs involving more women as well as laws and policies that enable girls and young women to attend school. More studies in future especially longitudinal to ascertain any dynamism in development over time. Hence, in developing countries, there are still barriers limiting women and girls opportunity.

Published: July 2023

In this study, we present a 6-step linear multistep mehod in union with some newton-cote quadrature family for solving third order Linear Fredholm Integro-Differential Equation(LIDE). The schemes were derived using Vieta-Pell-Lucas Polynomial as the approximating function. The linear multi-step component is for the non integral part while the quadrature family is for the Integral part. The quaudrature methods Boole , Simpson 3/8 and Trapezoidal rule were separately combined with the linear multistep method. The qualititaive analysis of the scheme revealed that the method is consistence, stable and convergent. In order to further attest to the behavioural attribute of the methods, numerical experiments were carried out on some selected Initial Value Problems.The results from the tested problems and their absolute errors of deviation revealed that the new method is very suitbale for solution to the tested problems. The scheme when combined with Boole and Simpson 3/8 merhod, performed better with Tracendental function than when combined with Trapezoidal rule and vice –versa. The results further showed that the proposed method perform creditably well with lesser computional steps when compared with some existing methods when applied to the selected examples.

This paper presents the performance evaluation of a natural convection indirect solar dryer for drying white yam. Drying is the process of removing enough moisture from food to prevent decay and spoilage. Large quantity of yams are produced, therefore, there is need for drying the yams to minimize wastage. This study mainly tried to solve the problem of post harvest-loss using natural convection indirect solar dryer for drying white yam. The dryer was made from plywood with 10 mm thickness and consists of a solar collector and drying chamber which houses three trays with an upper vent for the exit of air. The result of no load showed that the dryer temperature could rise up to 60 . The average collector temperatures recorded from no load tests were 71.1 oC and 75.11 oC. The collector efficiency was found to be 53.1 and dryer efficiency was 10.5 . The drying rates for the load tests were found to be 0.081 kg/hr and 0.095 kg/hr. It was found that, the required 7.6% moisture content was obtained within 18 hours of drying. Therefore, farm products with an initial moisture content of 71.3% can be dried using this dryer.

Published: July 2023

A study on the Prevalence of Intestinal Parasitic Infections was carried out among Internally Displaced Persons and the host community in Mubi North Local Government Area of Adamawa State. 400 stool samples were collected from three communities namely, Barama,Yelwa and Wuro Hande. The Stool samples was processed using formol ether concentration technique and examined under microscope for the cyst of parasites with the aid of identification manual..121 were infected with a Prevalence rate of (30.3%). Eight Parasites species were encountered namely, Ascaris lumbricoides(36.1%), Schistosoma mansoni (22.5%), Ancylostoma duodenale (12.6%), Entamoeba histolytica (5.3%), Hymenolepis nana (2.6%), Enterobius vermicularis (3.0%), Entamoeba coli (6.0%) and Giardia lamblia (7.0%.). Ascaris lumbricoides was the most prevalent parasite while Hymenolepis nana was the least encountered. Internally Displaced Persons were more infected (34.5%) compared to the host community (26.0%), though statistically not significant P>0.05. Males were more infected among the IDPs (41.1%) than females 29.1%, while females (27.2%) were more infected than males (24.4%) in the host communities.. The study showed that infection was wide spread within the communities irrespective of settlement status. This could be attributed to poor personal hygiene, and indiscriminate dumping of waste, coupled with the challenges of portable water supply. There is the need for improvement in the availability of portable water supply and proper waste management in mubi and environs.

Fruit flies are the main pests that attack various types of fruit vegetables and fruits that can caused a damage in the quality and quantity of production. Fruit flies controlling by chemical insecticides is common to use nowadays, but excessive use of chemical insecticides has a negative impact on the health and environment. One alternative to control the fruit flies is using oleoresins of Chromolaena odorata leaf. This study aims to determine the effect of C. Odorata leaf oleoresin on increasing the mortality of fruit fly pests (Bactrocera cucurbitae). This research used an experimental method with Completely Randomized Design (CRD) which had 6 treatment levels, namely: N0 (Aquadest), N1 (Oleoresins 2%), N2 (Oleoresins 4%), N3 (Oleoresins 6%), N4 (Oleoresins 8%), N5 (Oleoresins 10%), was replicated 4 times so there were 24 experimental units. The results showed that the application of C. Odorata leaf oleoresin had no sigificant effect on mortality percentage and mortality rates, but oleoresin had the potential to increasing fruit fly mortality as concentrations increased. It is necessary to test the increasing concentration of oleoresin > 10% to control fruit fly pests.

SMK Islam Kunjang is a relatively developing school in any things; such as the system of administration, relation, or teaching methodology or technique, because it runs for about 14 years old. SMK Islam Kunjang is located suburbs. Absolutely, most students were less in spirit to study more over English. The teacher has been trying to determine the technique in teaching especially teaching writing. The students’ writing was poor. One of the problems was the technique used. Examples Non-Examples technique is one of the cooperative learning strategies that employ images and videos connected to fundamental skills and encourages students to be more creative and engaged in developing their own ideas about the subject that they are observing. In this study, eleventh-grade students at SMK Islam Kunjang in the academic year 2022–2023 were asked to write descriptive texts with examples and without examples to see if this improved their writing abilities. Action research in the classroom is the methodology (CAR). The tools were an observational study, a questionnaire, and a test. This study focused on TKJ 1's eleventh grade, which had 45 pupils. The results showed that the average student in cycle one was 70.80%, whereas the average student in cycle two was 81.66. According to the means of cycles one and two, there was a considerable improvement from 77.78 to 81.66 and 70.80% to 89.68% of students passing the indicator of success, respectively. Additionally, pupils showed higher interest in learning how to write descriptive texts. Therefore, it is advised that students use the examples-not-examples strategy to improve their writing, particularly in descriptive texts.
