ABSTRACT

The Nigeria banking sector over the year has experience noticeable innovation and changes in the products and service delivery. The advancement in information technology has brought about changes and other products such as automated teller machine [ATM]. Which was aimed at enhancing effective service delivery by bring money to the door step of customers 24 hours a day seven days a week. Its one of the component that make up for electronic banking (e-banking). Automated Teller Machine is described as an electronic machine that enable customer to primarily withdraw paper money or carry out other banking transaction. This research primary objective will be to assess the effectiveness of ATM in providing efficient and reliable banking services specifically at Federal Polytechnic Bauchi where some of the ATM is sited. The research made use of both primary and secondary data in conducting the study. The data collected was used to test the hypothesis postulated: that ATM has no significant impact on banking service delivery using chi- square. The result of the study indicates that ATM to some extent has enhanced banking service delivery but not fully. The study recommends the need for proper maintenance of the machine, regular and prompt of restocking cash and encouragement to go cashless e.tc.

Abstract

Samples of soil were collected from three (3) different locations in Zaria, northwest part of Nigeria and the Geo-accumulation index () was used to check the level of pollution in the soil. The result shows that of the metals falls within the class of 0 and 1. Considering permissible levels of metals, this reveals that the soil in Zaria and environ is not enriched in these potentially toxic elements. Also the concentrations of the elements determined were compared to the range, mean, and median values of the World soil.

ABSTRACT

We examine certain general problems of the employment of analytic functions in the solutions of boundary-value problems involving Laplace’s equation  (i.e finding a solution in the boundary), considering Dirichlet’s, Neumann’s and Mixed or Gauss’s problems. Conformal mapping is used to map a given complicated domain onto a simpler one, where the solution is known or can be found easily. This solution is then mapped back to the given domain; this is the idea that works due to the fact that harmonic functions remains harmonic under conformal mapping. And we proceed to show that for a mapping  to be conformal in any domain, it is necessary and sufficient that  be analytic in that domain and that  for all  in the domain, and also shows that a mapping which preserves the magnitude of angles but not necessarily the sense is non-conformal rather Isogonal.

ABSTRACT

The powdered leaves of Chenopodium ambrosioides (L) were extracted in 70% acetone and concentrated using rotary evaporator at a temperature below 40oC. The extract was partitioned in diethyl ether and distilled water. The aqueous phase containing the tannins was separated and freeze dried.  Column chromatography (CC) was performed using acetone toluene and formic acid (6:6:1) as the solvent system. Tannin fractions were isolated and spotted using CC and ferric chloride solution. The fractions were pooled based on Rf value similarities. FT-IR P800S system was used for the determination of functional group. The HPLC analysis was carried out using lab solution system equipped with UV detector and Pinnacle C18 RP column (150 X 4.6mm ) with injection volume of 20µl and the flow rate of 1ml/min. Acetonitrile and distilled water (80:20) were used as the mobile phase. The result of the extraction  gave 8 spots with Rf values; 0.88,0.10,0.16,0.4,0.41,0.5,0.56, & 0.6. The tannin fraction gave one spot with Rf value 0.11 and the standards gave 3 spots with Rf values, 0.11, 0.2,& 0.3) The FT-IR analysis confirmed the presence of tannins functional groups. The HPLC result detected the presence of hydrolysable tannin (gallotannins) which was found to exhibit marked activity on E. coli, S. typhi, S.  aureus and C. albicans.

Abstract

A total of 60 Anak strain broiler finisher birds of 28 days of age were used in a twenty eight (28) days feeding trial to determine the effect of bambara nut sievate fortified exogenous enzymes on the serum biochemical values and haematological assays of finisher broiler birds. Four experimental diets were formulated such that bambara nut sievate fortified exogenous enzyme was incorporated in the finisher broiler diets at 0%, 5%, 10% and 15% dietary levels to replace soybean in the experiments in diets T1, T2, T3 and T4 respectively. The 60 finisher broiler birds were divided into 4 experimental groups of 15 birds per group and were randomly assigned to the 4 treatment diets and replicated three (3) times (5 birds per replicate).  The haematological parameters such as Hb, PCV, RBC. and WBC increased with respect to control except in treatments 3 and 4.  Furthermore, MCV, MCH and MCHC, were significantly different (p>0.05).  Serum biochemical parameters such as urea, total protein cholesterol and globulin were significantly different (p<0.05) between the treatments, while creatinine and albumin were similar (p>0.05) between the treatment means. However, all the parameters of the WBC were not significantly different (p>0.05).  All serum biochemical elements were significantly different (p<0.0) between the treatments. These results suggest that bambara nut sievate fortified exogenous enzymes could be included in the diet of finisher broiler birds up to 15% level without any harmful effect on the animal.

Abstract

The Benzene ring is an important example of conjugated molecule, and also an important building block of many organic semiconductors (OSC). However a single benzene ring is not yet large enough to bring the band-gaps Eg into the OSC regime. The molecular geometries of the   Hydroxylbenzene group have been studied using ab-initio Quantum chemical calculations at the Restricted Hatree-fock (RHF) with 6-31G(d,p) basis set. Also Density functional theory (DFT) at the B3LYP have been carried out  at the same basis set for inclusion of electron correlation. The electronic properties calculated  are Bond length, Bond angle, total energy, energy gap, ionization energy, electron affinity, electrophilic index, Hardness and softness. Some of the properties computed like bond lengths and bond angles by DFT are in good agreement with experimental values but those computed from RHF over estimated the results. The energy gap decreases with the substitution of OH radical in the Benzene molecule. The study was performed using Gaussian 03W software.

Keywords: Benzene, Bond length, Energy gap and DFT,  RHF

ABSTRACT

Studies on Mosquitoes in Hadejia emirate, Jigawa State, Nigeria revealed the presence of eight species; 107 (16.09%) Aedes aegypti, 123 (18.50%) Ae. africanus, 41 (6.16%) Ae. albopictus, 60 (9.02%) Ae. furcifer, 76 (11.43%) Ae. taylori, 42 (6.32%) Ae. luteocephalus, 77 (11.58%) Culex decens, 31 (4.66%) Cx. dutton and 82 (12.33%) Mansonia Africana. Within the (8) Local Government Areas sampled, Hadejia has the highest member of mosquitoes obtained. Anopheles species were only reported from Auyo and Guri has the least number of Mosquitoes Aedes africanus was the most abundant while Anopheles funestus was the least. The mosquitoes identified in this study are of public health importance and there is an urgent need to control them by treatment of their breeding places and indoor residual spray.

ABSTRACT:

A study of the icthyofauna resources of the coastal waters of Ondo State of  Nigeria conducted for 18 months (June 2011-December, 2012) revealed the presence of 67 finfish species with the clariids(especially Clarias gariepinus and Heterobranchus bidorsalis) and cichlids(especially Oreochromis niloticus and Coptodon zilli) dominating the stock accounting for 42% and 16% respectively. Other predominant families were  A high ’Claroitedae’(Chrysichthys nigrodigitatus) with 9.2% contribution, ’Channidae’(Parachanna africana) with 8.7%, Osteoglossidae (Heterotis niloticus) with 7.1%, Gymnarchidae( Gymnarchus niloticus), Mugilidae (Mugil cephalus) and Clupeidae (Ethmalosa fimbriata). Lausanne Index of Abundance was 89.7% while Margalef.s index( a measure of species richness) was 5.18.  The Length-weight relationships of these predominant fishes showed negative allometric growth pattern. A high level of heterogeneity of stock was observed as revealed by Simpson Index and Shannon-Weiner Index of General Diversity (H i) which were 0.13 and 0.35 respectively. A lot of similarity in species composition existed as revealed by Evenness Index(E) of 0.20 and Berger-Perker Index of 0.88. There was comparatively higher catches of fish in the dry season than the wet season probably due to reduced water volume which concentrated the fishes for easier catchability. The author recommends the need to protect the existing stock especially the monospecific families like the Osteoglosidae and Gymnarchidae through regular monitoring of the physicochemical parameters of the coastal waters which are highly susceptible to crude oil pollution, Ondo State being a crude oil-producing area. More funds should be committed by the government to researches on population dynamics and biomass estimate of our coastal waters.

Abstact

The molecular geometries of the hydroxyl radical  on the monosilacyclobutane molecule have been studied using ab-initio Quantum chemical calculations at the Restricted Hatree-fock (RHF) with 6-31G(d,p) basis set. Also Density functional theory (DFT) at the B3LYP have carried out  at the same basis set for inclusion of electron correlation. Cyclobutane is the original Molecule before replacing one carbon by Silicon atom. This  led/resulted in the study of three molecules. The electronic properties calculated  are Bond length, Bond angle, total energy, energy gap, ionization energy, electron affinity, electophilic index, Hardness and softness. The result in this study show that calculated Bond length,  Bond angle and total energy for cyclobutane have been found in good agreement with previous studies. For the other molecules, we have not found a reference data, so this study supplies a new data in this aspect. These calculations have been performed using Gaussian 03 package. 

Keywords: Ab-initio, Cyclobutane, DFT, Bond length, silicon.
