Authors: Ekpo Effiong, OJI , Inah Edet, MONDAY
Published: July 2020

The study examined the influence of family background on students’ dropout from secondary schools in Yakurr local government area of Cross River State. The study adopted the descriptive survey design and paired t-test and independent t-test were used in analyzing the data collected. The instrument for data collection was a structured questionnaire known as the family background and students’ dropout questionnaire (FBSSDQ)made by the researcher. One hundred and fifty (150) students were randomly sampled from five (5) selected secondary schools from the study area. Fifty (50) students were used for trial testing outside the population of the study. Kuder Richardson 20 (KR20) reliability estimate was used to determine the reliability indices of the three sub variables as follows: family size = 0.78, parents’ attitude = 0.81 and parents’ socio-economic/educational status = 0.73 respectively. The results showed students do drop out from schools and that this situation is attributed to certain factors such as family size, parents’ attitude, parents’ socio-economic status and educational background. It was recommended that parents should be fully educated on population size and education, there should be a massive education campaign to enlighten the parents and the general society on alternative ways of checking school dropout and the government should not shift the whole responsibility of financing education to parents since most of the parents are financially handicap and poor.

L’alternariose de la tomate est une maladie cryptogamique dévastatrice dans les zones maraichères du Burkina Faso. Tous les organes de la plante (tiges, feuilles, fruits) sont attaqués, entrainant une baisse importante du rendement et une dépréciation de la qualité de la production. Dans la présente étude, quatre huiles essentielles de plantes aromatiques locales (Cymbopogon schoenanthus, Lippia multiflora, Ocimum americanum, et Ocimum basilicum) ont été testées, pour évaluer leurs propriétés d'inhibition sur la croissance radiale du mycélium d’un isolat pathogène de Alternaria sp. Le test in vitro des doses de 100%, 50%, 10%, 5% et 1% a montré que toutes ces huiles essentielles possèdent une activité antifongique sur ledit isolat. Les taux d’inhibition des huiles essentielles sur la croissance du champignon étudié vont de 25,96% à 100%. La meilleure inhibition a été enregistrée avec l’huile essentielle de Cymbopogon schoenanthus, de Ocimum basilicum et de Lippia multiflora pour les concentrations supérieures à 1%. Il ressort donc de cette étude que trois huiles essentielles, stoppent la croissance mycélienne de l’isolat pour des doses allant de 5% à 100%. Ces huiles (Cymbopogon schoenanthus, Ocimum basilicum et Lippia multiflora) pourraient être utilisées pour la mise au point de phytopesticides afin d'atténuer l’utilisation intensive et hasardeuse des pesticides.Mots clés:  Alternariose, activité antifongique, plante aromatique, tomate.

English Title: Effects of four essential oils on radial mycelial growth of an isolate of Alternaria sp. in Burkina Faso

Early blight of tomato is a devastating cryptogamic disease in the vegetable gardens in Burkina Faso. All plant’s organs (stems, leaves, fruits) are attacked causing a significant decrease in the yield and a depreciation of the quality of the production in the field. In the present study, four essential oils of aromatic plants (Cymbopogon schoenanthus, Lippia multiflora, Ocimum americanum, and Ocimum basilicum) were tested to evaluate the inhibition properties of these oils on the radial growth of the mycelium of an isolated pathogen of Alternaria sp. In vitro tests at doses of 100%, 50%, 10%, 5% and 1% showed that all these essential oils tested have antifungal activity on said strain. The inhibition rates of essential oils on the growth of the fungus studied range from 25.96% to 100%. The best inhibition was recorded with the essential oil of Cymbopogon schoenanthus, Ocimum basilicum and Lippia multiflora for applied concentrations more than 1%. It therefore emerges from this study that three essential oils stop the mycelial growth of the isolate for doses ranging from 5% to 100%. These oils (Cymbopogon schoenanthus, Ocimum basilicum and Lippia multiflora) could be used for the development of phytopesticides in order to reduce the intensive and hazardous use of pesticides.Keywords: Early blight, antifungal activity, aromatic plant, tomato.

Au Sénégal, les adventices constituent une des contraintes majeures à l’augmentation de la production agricole. Une étude dans l’objectif de caractériser l’enherbement dans les parcelles cotonnières au Sénégal a été réalisée. Celle-ci a été réalisée grâce à la méthode appelée « tour de champs ». A partir de 139 relevés effectués, 204 espèces réparties en 118 genres appartenant à 35 familles botaniques ont été répertoriées. Les Familles des Fabaceae (22,1%), Poaceae (20,1%), Malvaceae (9,3%) et des Cyperaceae (7,8%) dominent cette flore et représentent près de 60% de l’effectif total. Les Dicotylédones sont dominantes avec 68,6%. Sur le plan agronomique, Hyptis suaveolens, Pennisetum pedicellatum, Digitaria horizontalis, Dactyloctenium aegyptium et Kyllinga squamulata constituent les adventices majeures. L’analyse de l’indice partiel de nuisibilité révèle que 47 espèces sont potentiellement nuisibles dont dix constituent les plus nuisibles aux cotonniers dans le bassin cotonnier du Sénégal. Une gestion efficace contre ces espèces devrait être envisagée pour réduire les pertes de rendement dues aux adventices.Mots clés : Adventices, nuisibilité, infestation, cotonnier, rendement, Sénégal.

 

English Title: Degree of weed infestation in Senegal's cotton basinIn Senegal, weeds are one of the major constraints to increasing agricultural production. A study was carried out to characterize grass cover in cotton plots in Senegal. This was carried out using the method known as "tour de champs". Based on 139 surveys, 204 species in 118 genera belonging to 35 botanical families were identified. The Families Fabaceae (22.1%), Poaceae (20.1%), Malvaceae (9.3%) and Cyperaceae (7.8%) dominate this flora and represent nearly 60% of the total number of species. Dicotyledons are dominant with 68.6%. Agronomically, Hyptis suaveonlens, Pennisetum pedicellatum, Digitaria horizontalis, Dactyloctenium aegyptium and Kyllinga squamulata are the major weeds. Analysis of the partial harmfulness index reveals that 47 species are potentially harmful, ten of which are the most harmful to cotton plants in the cotton basin of Senegal.

RNA interference: recent trends and its application in controlling Neglected Tropical Diseases (NTDs)
Authors: Kargbo Alpha , Jawo Edrissa , Mendy Pierre A. , Entonu Moses Edache
Published: July 2020

Degradation of homologous mRNA in some cells or organisms is possible through the introduction of double-stranded RNA (dsRNA), via a process called RNA interference (RNAi). The dsRNAs are processed into short interfering RNAs (siRNAs) which consequently bind to the RNA-induced silencing complex (RISC), and causes degradation of target mRNAs. RNAi has been widely used to study gene modifications and functions hence has the possibility to control disease pathogens or vectors. This promising potential led researchers to discovery gene control mechanisms in tropical diseases, by manipulating genes of pathogens and vectors, protozoans, animal parasitic helminthes and disease-transmitting vectors, such as insects. Many pathogens and vectors cause severe parasitic diseases in tropical regions and it is challenging to control them once the host has been invaded intracellular. The aim of this work is to show how RNA interference can be used as treatment candidate for controlling some neglected tropical disease as it is highly effective in impeding parasitic development and their proliferation within their host.Keywords: Mosquitoes, Parasitic protozoa, Helminthes, Insect vector
Niacin downregulates chemokine (c-c motif) ligand 2 (CCL2) expression and inhibits fat synthesis in rat liver cells
Authors: Xing Xuekun , Wang Hui , Zhao Lan , Bai Yunxiao , Xie Fei , He Junjie , Lv Chenxi
Published: July 2020

Purpose: To elucidate the role of chemokine (c-c motif) ligand 2 (CCL2) in fat metabolism in hepatocytes.

Methods: Following partial hepatectomy, regenerated rat liver cells were isolated and cultured for 24 h were transfected with recombinant plasmid pEGFP-N1-CCL2 using liposomes. Niacin was added to the culture medium to inhibit fat synthesis. CCL2 expression was measured using western blot, while the expression of acly-coa synthetase long chain family 4 (ACSL4) and apolipoprotein E (ApoE) were assessed using real-time PCR.

Results: At 12 h after transfection, GFP-positive rates in the pEGFP-N1 and pEGFP-N1-CCL2 transfection groups were 42.4 ± 5.6 % and 45.1 ± 3.5 %, respectively. Expression levels of CCL2 increased over time in pEGFP-N1 transfection group, pEGFP-N1-ccl2 transfection group, and niacin and pEGFP-N1-ccl2 transfection co-treatment group; however, CCL2 expression levels in the niacin and pEGFP-N1-ccl2 transfection co-treatment groups were similar to that of pEGFP-N1 transfection group, which were significantly lower than those of the pEGFP-N1-ccl2 transfection group. Expressionlevel trends of fat-related genes ACSL4 and ApoE were similar to that of CCL2.

Conclusion: Niacin downregulates the expression of CCL2, thereby inhibiting lipid synthesis in liver cells.

Albiflorin attenuates inflammation and apoptosis by upregulating AMPK-mediated expression of CDX2 in a mouse model of ulcerative colitis
Authors: Xu Xiaoping , Liu Haiyan , Pan Yuan , Lui Zhaohui , Chen Dong , Zhang Lei , Yuang Hong
Published: July 2020

Purpose: To investigate the mechanism underlying the ameliorative effect of albiflorin (AF) on ulcerative colitis (UC) in dextran sulphate sodium (DSS)-induced mice model.

Method: Female C57BL/6 mice were administered DSS to establish a mice model of UC. After one week, the mice received AF, and the body weight and length of colon were measured. The histopathological features of colon tissues treated with hematoxylin-eosin (H & E) stain were examinedby microscopy. Expression of inflammatory cytokines and apoptosis-related proteins were determined using enzyme-linked immunosorbent assay (ELISA) and western blotting.

Results: The relative abundance of goblet cells and crypts of mice were significantly reduced in DSSinduced UC mice model; furthermore, focal ulcers and mucosal damage were apparent. Moreover, treatment with DSS decreased body weight and colon length, downregulated Bcl-2 and AMPK pathwayrelated proteins, increased inflammatory cytokines levels, and upregulated Bax and cleaved caspase-3. In contrast, treatment with AF completely ameliorated DSS-induced effects.

Conclusion: AF treatment attenuated DSS-induced inflammation response and apoptosis via AMPK pathway and modulation of CDX2 expression in UC mice model.

Trifluorobenzamidine prevents allergic rhinitis by regulating IgE, IL-4 and IL-5 in T-cells
Authors: Zhang Yongbo , Wu Zhuo , Yang Yihui , Ding Lu
Published: July 2020

Purpose: To investigate the effect of trifluorobenzamidine (TBI) on a mouse model of ovalbumin (OVA)- induced allergic rhinitis.

Methods: Allergic rhinitis was established in mice via sensitization on days 1, 5 and 14 through intraperitoneal injection of OVA (100 μg) in PBS. On day 15, the mice were subjected to intranasal exposure to OVA (1.5 mg dissolved in PBS). Prior to 10 days of intranasal exposure to OVA, the micewere treated with TBI at doses of 5, 10 and 20 μg/kg. Cytokine levels were determined using enzymelinked immunosorbent assay (ELISA) kits, while cyclooxygenase (COX)-2 and caspase-1 activity were assayed with western blotting.

Results: Treatment with TBI significantly (p < 0.05) reduced OVA-mediated increases in nasal rub scores, and decreased serum levels of IgE, TNF-α, thymic stromal lymphopoietin (TSLP), IL-1β and histamine in mice. It also significantly regulated spleen weight and IL-4 secretion (p < 0.05) in OVAadministered mice. TBI significantly downregulated the expressions of IL-5, IL-13, TNFα, TSLP, IL-1β and IL-6 (p < 0.05). Administration of TBI caused a marked reduction in OVA-mediated increase in caspase-1 activity in mice intranasal tissues, and also significantly reduced OVA-induced excessive production of MIP-2 and ICAM-1 (p < 0.05). Moreover, TBI prevented OVA-induced infiltration of eosinophils and mast cells into intranasal tissues (p < 0.05).

Conclusion: TBI reduces levels of IgE and various pro-inflammatory cytokines in OVA-administered mice. It also regulates Th1:Th2 ratio, inhibited activity of caspase-1, suppressed mast cell/eosinophil infiltration and reduced ICAM-1 and MIP-2 levels. Therefore, TBI possesses inhibitory potential against rhinitis allergy, and thus can potentially be developed as a new treatment strategy for asthma.

Authors: Kim Won Tae , Kim Kang Min , Kang Jae Seon
Published: July 2020

Purpose: To determine the antioxidant and hepatoprotective effects of decursin and decursinol angelate (D/DA) isolated from Angelica gigas Nakai (AGN).Methods: The 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity of D/DA was assessed in a rat model using blood tests, western blotting, and histopathological analyses to identify the pharmaceutical effects of D/DA on liver enzymes and liver morphology.Results: The DPPH scavenging activity of D/DA was 47.11 μg/mL. Administration of D/DA to carbon tetrachloride (CCl4)-treated rats led to a decrease (13.59 %) in the total liver mass of control rats. Decursin and decursinol angelate also lowered the levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), but increased the concentrations of antioxidant enzymes in the liver, including catalase (CAT) and glutathione peroxidase (GPx). Histological examination revealed that D/DA also reduced hepatocellular damage in the rats.Conclusion: D/DA from AGN has significant anti-hepatotoxic and antioxidant activities, and thus, is a potential herbal drug for treating liver damage.

Keywords: Decursin, Decursinol angelate, Antihepatotoxicity, Antioxidant, Angelica gigas Nakai

Purpose: To examine the glucose uptake stimulatory activity of the root extract of Cissus javana DC. (Vitaceae) in Lδ myotubes of rat, and also to identify the extract’s active principles.Methods: The methanol extract was prepared from Cissus javana tuberous roots and evaluated for glucose uptake stimulatory effects on Lδ rat muscle cells and inhibitory activity against α-glucosidase. The chemical components were isolated using several chromatographic techniques, and their structures characterized by spectroscopic methods. Each isolate was then assayed for glucose uptake stimulatory and α-glucosidase inhibitory activities.Results: The extract (100 μg/ml) exhibited glucose uptake stimulatory effect (70.9 % enhancement) and α-glucosidase enzyme inhibitory activity (100 % inhibition). Through chromatographic separation, bergenin, stigmast-4-en-3-one and β-sitosterol were isolated and identified. Bergenin, at 100 μg/ml (0.3046 mM), increased glucose uptake by Lδ myotubes by 50.5 % without toxicity. At the same concentration, bergenin showed no inhibition on α-glucosidase enzyme, while stigmast-4-en-3-one and β-sitosterol exhibited 98.6 and 40.6 %, inhibition, respectively.Conclusion: This study is the first report on the chemical constituents, and the glucose uptake stimulatory and α-glucosidase inhibitory activities of Cissus javana DC. roots. The findings reveal the antidiabetic potential of the plant and the glucose-uptake enhancing activity of bergenin.

Potential inappropriate prescribing among ambulatory elderly patients in a geriatric centre in southwestern Nigeria: Beers criteria versus STOPP/START criteria
Authors: Akande-Sholabi Wuraola , Ajilore Oluwatobi C. , Showande Segun J. , Adebusoye Lawrence A.
Published: July 2020

Purpose: To identify potentially inappropriate prescribing in ambulatory elderly patients and compare the appropriateness of guidelines; Beers' and Screening Tool of Older Person’s Prescription (STOPP)/Screening Tool to Alert Right Treatment (START) criteria to detect potentially  inappropriate prescribing among the elderly.Methods: A retrospective study was conducted using case files of 335 elderly patients aged ≥ 60 years between 1st January and 31st December  2016, using a data extraction sheet. The 2015 American Geriatrics Society (AGS)-Beers Criteria, and version 2 of the STOPP and START were  subsequently used to identify the Potentially Inappropriate Prescribing (PIP) and Potential Prescribing Omissions (PPOs).Results: Mean age of patients was 69 ± 0.4 years (range 60 - 85 years) and 219 (65.4 %) were females. An average of 4.2 medications per patient prescription was found. The Beers criteria identified 26.5 % PIP, while STOPP criteria identified 57.1 % PIP. START detected 29 PPOs in 15 (4.4 %) of the patient’s prescription. The most prevalent disease conditions were hypertension 235 (70.1 %) and osteoarthritis 64 (19.3 %). Polypharmacy was significantly associated with PIP in both Beers (p = 0.002) and STOPP (p = 0.001) criteria.Conclusion: The prevalence of PIP is high among elderly patients. The STOPP/START criteria identified a higher proportion of PIP among elderly patients compared with Beers criteria. The frequency of PIP should stimulate efforts to curtail potentially inappropriate prescribing and may require the need for advocating for a national criterion to be adopted by health care professionals in Nigeria.

No Sex In The City and Postfeminist Discursivity from Arab Diaspora
Authors: Abdullah Muhammad
Published: July 2020

The novel No Sex in the City by Randa Abdel-Fattah juxtaposes Islamic progressive and Western secular viewpoints on dating culture, relationships, sex, and marriage. The patterns of halal1dates are described in a light-hearted, yet meaningful tone. These are religio-culturally appropriate ways of approaching prospective life partners, where the agency of final decision, in most cases, is with the participants. Instead of being defensive or apologetic about Islamic traditions and values, Abdel-Fattah vocalizes them in a rational way through the lead lady, Esma. The protagonist, Esma, is an Australian Muslim with Turkish roots. Muslim diaspora in the West is in the middle of the continuum from liberalism to conservatism. Despite living in a non-Islamic culture, followers of Islamic ideology are connected through a shared culture driven by Islam. Faith-based practices are beyond any geographical bindings. So, for Muslims, wherever they may live, there are similarities in the way they conduct their lives. In fact, the blurring of boundaries between religious and cultural is minimal in diaspora Muslim communities. Abdel-Fattah has delicately balanced secular and religious in this work where freedom and right to exercise choice wins at the end. Pleasantly, these women possess sensual sensitivities and affectionate desires, but Saudi/Islamic sensibilities obligate them to tie the marriage knot before pursuing any physical pursuits. This in no way incapacitates them from loving men, but rather appropriates the meaning of love in an Islamic framework. The diversity of situations and respective choices made by these girls during the novel also allude to the socio-cultural dynamics, patterns, and matrimonial preferences of Saudi women.

Published: July 2020

El enorme poder financiero que han adquirido las multinacionales no solo ha desestabilizado a las personas, sino también a los Estados, que pierden su capacidad para decidir solos sus políticas económicas y sociales, y a las organizaciones internacionales, cuyos poderes provienen de los Estados. Frente a esta situación compleja, resulta muy importante la existencia de una regulación transnacional adecuada. Varios instrumentos legales completan los derechos nacionales del trabajo y el derecho de la OIT, los mejoran, sin sustituirlos o transformarlos, porque también tienen sus defectos. Las soluciones actuales y sus debilidades constituirán el objeto de la primera y de la segunda parte respectivamente del artículo. Las conclusiones contienen algunas sugerencias para superar mejor las consecuencias sociales negativas de la globalización.

Published: July 2020

Cuaca memiliki peran sangat penting terhadap efisiensi penerbangan. Kerapatan udara rendah membuat pesawat membutuhkan landasan pacu yang panjang ketika lepas landas. Hal tersebut dapat meningkatkan beban kerja mesin untuk menambah kecepatannya di runway. Kondisi atmosfer selalu dinamis dan tidak dapat dikendalikan. Pesawat harus mendapatkan gaya angkat maksimal dengan memperhitungkan kondisi tertentu. Operator penerbangan hanya dapat menyesuaikan dengan kondisi meteorologi tersebut untuk memperhitungkan efisiensi penerbangan. Penelitian ini dilakukan di Bandara Supadio Pontianak menggunakan data observasi Stasiun Meteorologi Supadio Pontianak tahun 2016. Data yang digunakan meliputi meliputi suhu udara, suhu titik embun, dan tekanan udara. Berdasarkan hasil perhitungan didapatkan bahwa suhu udara memiliki pengaruh yang paling signifikan terhadap gaya angkat pesawat. Gaya angkat maksimum harian terjadi sekitar pukul 05.00 – 06.00 WIB dan gaya angkat minimum terjadi sekitar pukul 13.00 – 14.00 WIB. Gaya angkat terbesar bulanan terjadi pada bulan Januari dan terkecil pada bulan Agustus.

Breve análise à liturgia penitencial em Jl 2,12-14
Authors: Furghestti Jane Maria
Published: July 2020

Jl 2,12-14 descreve o contexto de uma liturgia penitencial, na qual o próprio YHWH convida o povo para retornar a Ele de todo coração. O pano de fundo do texto de Jl 2,12-14 é de uma catástrofe natural vivida pelo povo de Judá-Jerusalém. Por causa desta condição crítica, a comunidade enfrenta situações extremas, como a fome, a carência de produtos para a sua sobrevivência e uma completa apatia espiritual. Contudo, ainda há uma esperança de que através de uma celebração litúrgica com toda a comunidade reunida se possa mudar tal contexto desfavorável. A ação do profeta é positiva, pois confia na assistência divina. O profeta, então, faz um apelo a toda a comunidade para um retorno a YHWH, com todo o coração, com jejum, com lágrima e com lamento. É dentro deste contexto que se desvela o tema do yôm YHWH, como um Dia de Salvação para o povo de Judá-Jerusalém. A convocação do profeta para o retorno do povo ao seu Deus é interpretada como um chamado para o povo honrá-lo, com ritos religiosos verdadeiros e gestos sinceros. Neste contexto, Jl 2,12-14 expressa uma relação de comunhão entre YHWH e seu povo, o qual retorna ao seu Deus de todo o coração.

Published: July 2020

Malaria parasites and packed cell volume offree range poultry was conducted on one hundred free range chickens collected from three communities in Abeokuta (Osiele, Lafenwa and Kuto). The results revealed that out of the 100 free range chickens examined, 13(13%) were infected with avian malaria parasite. Hematological parameter i.e. packed cell volume (PCV) revealed that chicken with PCV range 16-20 were 33.33% positive for malaria parasite. Others between PCV ranges 21 – 25 were 33.3%, while those between PCV ranges of 26 – 30 were 16.66% and those with PCV range of 31 – 35 were 16.67%.Chi-square analysis showed a significant difference between packed cell volume and malaria parasite(p<0.05). However, no significant difference was observed between sex and malaria parasite(p>0.05). The presence of avian malaria parasites in the study area could be of some epidemiological implications since the infected poultry could act as reservoir for malaria parasites.

Food, drinking water, table and utensil swab and hand washing water samples were examined for Salmonella sp contamination. Microbiological examination of samples using lactose broth, Cystine- Lactose-Electrolyte-Deficient (CLED) agar and Eosin-Methylene-Blue (EMB) agar was done to identify Salmonella sp, other organisms and indicator organisms. Indicator organisms identified were Aerobocter aerogenes and Escherichia coli. Other organisms include Streptococcus faecalis, Proteus sp and Staphylococcus aureus. 74.7% of examined samples showed Salmonella sp contamination while 89.8% of examined samples were contaminated with indicator organisms. Observed Salmonella sp were also examined biochemically to identify different species/strains. Species/strains identified were Salmonella typhi, S. paratyphi A, S. paratyphi B, S. cholerae-suis, S. enteritidis. There was a significant association between sanitary conditions and the occurrence of S. typhi in food, water, surroundings. It is very likely that poor hygiene and sanitary conditions encourage the occurrence of S. typhi in water, food, surroundings. Personal and environmental hygiene should be strictly adhered to especially in the study area so as to prevent and control S. typhi infections.

Authors: Clarkson G J , Adah C A
Published: July 2020

The reactions of galactosyl, mannosyl and lactosyl barbiturates with 4-benzyloxybenzyl chloride and á- halo amide with galactose barbiturate were investigated. The products (benzyloxybenzyl-galactosyl barbiturate, benzyloxybenzyl-mannosyl barbiturate, benzyloxybenzyl-lactosyl barbiturate and galactose amide) were characterised by high field nuclear magnetic resonance spectroscopy, mass spectrometry, carbon, hydrogen and nitrogen combustion analyses and further characterised as per- acetate. The alkylation or the barbituric salts proceeds well with the electrophiles and are routes to novel C-glycosyl lectin binders.

The transportation cost of goods in any company or organization is a pivotal element in determining the total cost of production and also the net profit that will be made. The main aim of this study is to minimize the cost of transporting goods produced at Grand Cereals Limited, Jos, which is reducing the cost of transportation from the major plant where the goods are produced to the various distribution centers. Data was collected on the average quantity of Brabusco Maize Flour (10 kg), Grand Pure Soya Oil (10 litres), Vita Chicks Pelletized Feeds (25 kg, 9 mm) and Royal Layer Concentrate Feeds (25 kg) produced monthly at the Jos plant, the average quantity demanded by major distributors across the country (Yola, Dutse, Minna, Abuja, Aba, Onitsha, Calabar and Ikeja) and the cost of transporting them. The Vogel's Approximation Method of the TORA Optimization System Software was used in solving the formulated transportation problem, and an optimal solution of N3,427,821.00 was obtained, which reduced the monthly transportation cost by N332,179.00. Furthermore, sensitivity analysis was carried out on the parameters after the optimal solution was obtained, which shows that the optimal solution is strongly sensitive to changes in the problem parameters. It was concluded that this work has reduced the transportation cost of the company and therefore recommended to the management of the company for adoption in planning their transportation schedule at a minimum cost.

Authors: Akombor A A , Tyona M D , Adelabu J SA
Published: July 2020

Optogeometric properties of La 2 O 3 (Lanthanum Oxide) thin films prepared by sol-gel technique have been investigated. Characterization was derived by M-line spectroscopy, X-ray diffractometry and waveguide Raman Spectroscopy. M-line spectroscopy measurements revealed a refractive index of 1.592±0.001 on Pyrex substrate for a wavelength of 543.4nm and thin film thickness of 850nm and 1.589±0.001 on silicon wafer and thickness of single layer is between 40 and 60nm. X-ray diffractrometry has shown that the film has monoclinic structure. Waveguide Raman Spectroscopy has revealed a mixture of La 2 O 3 and La 2 O 2 CO 3 (Lanthanum Oxide Carbonate) which are mainly nanocrystalline and polycrystalline respectively. The research has shown that the La 2 O 3 thin films produced can be used as a planar optical waveguide. The results obtained are comparable with the works of other scientists using different measurement techniques.

Authors: Edeoja A O , Owolabi A O
Published: July 2020

Water hyacinth is the world's worst water weed that is responsible for many environmental and economical problems. Nigerian fresh waters have been infested with this aquatic weed. In this work, a Natural Convection Mixed Mode Solar Dryer for drying water hyacinth to about 10% of its moisture content was constructed and tested as a component of controlling its infestation of the River Benue. The performance of the dryer was compared with the traditional open–air sun drying as the control for drying water hyacinth in Makurdi, Benue State Nigeria. The water hyacinth was dried for 8 hours each day for 4 days. 500g of water hyacinth on wet basis was dehydrated by about 437g on dry basis in 20 hours in the dryer while the control required 32 hours. The dryer was found to be technically more suitable for drying water hyacinth both in terms of the drying rate and quality of the dried product.

Published: July 2020

The suspended fine particulate matter concentrations in Makurdi and Otukpo Metropolis were measured using Haz-Dust Sampler (AMS 95015). The measurements were carried out at major observed emission sources such as residential and traffic related sources. On the average, traffic- related sources recorded the highest concentration of suspended fine particulate matter in both metropolis with the highest concentration in Otukpo metropolis (594 : g/m ). Generally the measured values from all the sources are above World Health Organization (WHO) standards and National Air Quality Standard (150-230 : g/m 3 for 24 hrs). Results show that Otukpo metropolis has the highest fine particulate concentrations from residential and traffic related sources. In order to keep the suspended fine particulate concentrations from rising above prescribed standards, appropriate control measures are recommended.

Published: July 2020

The use of photovoltaic cells (solar cells) for generation of electricity is no longer uncommon in Nigeria; this is because solar energy is undoubtedly part of the solution to the problem of dwindling fossil-fuel reserves. Various technologies of photovoltaic systems are imported from different countries and are being used locally with little or no information of their appraisal and field performance. In this work the performance efficiency of a silicon based solar panel operating under ambient conditions has been determined in an experiment using an off the shelf PV module. Measurements were taken while varying the direction of the panel, the tilt angle and illuminance during the day. Results show that PV installations within Benue State and most areas within the north-Central geopolitical region will perform optimally when installed at 15⁰ in the direction of the south. Apart from outlining the efficiency limiting factors, this work also provides an efficiency chart with data that can be used for solar installation.
