AN ASSESSMENT OF INDEXING AND ABSTRACTING SERVICES IN NUHU BAMALLI POLITECHNIC LIBRARY, ZARIA, NIGERIA

This paper examines the concept of indexing and abstracting, where index is define as systematic arrangement of entries designed to enable users to locate information in a document. While abstract at the other hand is an intellectual summary of an information package. The paper tried to finds out the availability and use of indexes and abstracts in Nuhu Bamalli Polytechnic Library (Annex) Zaria. The paper finds out that most types of indexes and abstracts are available and mostly used by Academic staffs and Students. It concludes that subject and citation indexes, as well as subject abstract were the most highly used by the respondents in the library; this could be due to lack of awareness about the other existing types of indexes and abstracts. However, some recommendations were made which includes; public awareness to the staffs and Students about the other existing types of indexes and abstracts and also more experts should be employed because as at present only one person is in charge of Indexing and Abstracting services.

The Occurence of Gastrointestinal Helminths in Slaughtered Cattle in Azare, North-East Nigeria

A Cross-sectional Study was carried out to determine the prevalence of gastrointestinal (G.I.) helminths parasites in slaughtered cattle at Azare abattoir, Katagum Local Government Area, Bauchi State, North-Eastern Nigeria. One hundred and twenty faecal samples were examined using the floatation and sedimentation method. Out of the total samples tested, G.I.helminths infections were detected in 62 samples tested, giving an overall prevalence of 51.6%. Class nematodes are the most diverse class (56.5%), followed by trematodes (35.5%), while cestodes are the least prevalent (8.1%). There was a statistically significant difference in G.I. helminths’ prevalence among different classes (p 0.05). The Red Bororo breeds had the highest prevalence of 75%, while the least was recorded in White Fulani and Sokoto Gudali, 40% each. There was a statistically significant difference in G.I helminth infection’s prevalence rate to breed (p < 0.05).This study revealed that Fasciola spp. (15%) is the most prevalent G.I.helminths parasites detected, followed by Oesophagostomum spp (11.7%);Haemonchus spp. (9.2%); Strongyloides spp. (8.3%), Schistosoma spp.(3.3%); and Moniezia spp. (1.67%). Our findings from the present study revealed a high prevalence of G.I. helminths species affecting cattle in Azare, North-East Nigeria. Therefore, there is a great need for proper advocacy on appropriate management, regular deworming practices, and improved cattle hygiene to boost animal production. This will help in curbing significant loss to Nigeria’s economy and the world in general

An Investigative Study on Impact of Frequency Dynamics in Load Modeling

Load modeling plays a significant impact in assessing power system stability margin, control, and protection. Frequency in the power system is desired to be kept constant, but in a real sense, it is not constant as loads continually change with time. In much literature, frequency dynamics are ignored in the formulation of load models for the basic assumption that it does not affect the models.&nbsp; In this paper, the composite load model was formulated with Voltage-Frequency Dependency (V-FD) on real and reactive powers and applied to estimate the load model. 2- Area network 4- machines Kundur test network was used for testing the developed model.&nbsp; The model was trained with measurements from a low voltage distribution network supplying the Electrical Engineering department at Ahmadu Bello University, Zaria. Both training and testing data were captured under normal system operation (dynamics). To evaluate the V-FD model performance, Voltage-Dependent (VD) model was examined on the same measured data. The work makes use of the Feed Forward Neural Network (FFNN) as a nonlinear estimator. Results obtained indicate that including frequency dynamics in modeling active power reduces the accuracy of the model. While in modeling reactive power the model performance improves. Hence, it can be said that including frequency dynamics in load modeling depends on the intended application of the model

The Dynamic Impacts of Idle Cash on Economic Growth in Nigeria (1985 – 2018)

The study investigated the dynamic effect of idle cash on economic growth in Nigeria from 1985 to 2018 employing a mixed methodology.&nbsp; The qualitative result revealed that political affluence, social status, treasury single account, asset declaration, biometric verification number, whistle-blower programme, and the empowering operation of economic and financial crime commission for anti-corruption crusade determine idle cash in Nigeria. On the other hand, the quantitative result revealed that idle cash has an inverse effect on economic growth in the short run. However, the long run result revealed a positive, and statistically significant effect on the economic growth, and it was found that idle cash Granger causes economic growth. We recommend that the government should provide a policy regulation framework that will regulate, track and checkmate the superfluousness of idle cash

Load modeling techniques in distribution networks: a review

Power system operation and control required models of generators, lines and loads to be accurately estimated, this is to enable operators make a reliable decision on the system.&nbsp; Generators and lines models are so far considered accurate, while load models are considered perplexing due to invention of new types of loads, distribution system are transforming from passive to active. Future distribution systems are desired to be smart and for a network to be smart the system as to be fully and accurately represented. Penetration of renewable energy and application of power electronic devices as well as participation of active customers in distribution systems make traditional methods of load modeling absolute. Accurate load modeling is required to address the new challenges evolving in the task of power system operation, control and stability studies. It is also an interest of power system researchers globally to realize Smart Networks (SNs), in which accurate load models are required. This work described a review of techniques and approaches for load modeling from traditional methods to the state of art in the area. In addition, gaps in the literature as well as research directions are also pointed out

Preliminary Evaluation of Some Qualitative Traits of Sugarcane Germplasm of North-Western Nigeria

Thirty five local sugarcane (Saccharum spp.) accessions were collected in an expedition in North-Western Nigeria, covering Sokoto, Kebbi, Zamfara,  Katsina, Kaduna, Kano and Jigawa States in September 2011. The germplasm accessions were maintained at Usmanu Danfodiyo University Sokoto. Data on leaf colour, leaf sheath colour, thrashability, ligular process, spines  (pubescence), stem colour and bud groove were collected. The study indicate that shape of the accessions could be used either directly or indirectly as a selection tool for pest resistance and mechanical cultivation in sugarcane. Leaf sheath colour and number of green leaves per plant could form additional selection tools for high photosynthesis efficiency to the already existing ones.Key words: Evaluation, Sugarcane, Germplasm, Characters, Accession

Screening of sweet potato feathery mottle virus resistant sweet potato (Ipomoea batatas L., Lam.) cultivars in Kebbi State, Nigeria

Sweet potato is a food security crop because of its ability to withstand adverse climatic conditions. This security, however, is being threaten by viral diseases and use of resistant cultivars remain the best management. This research was conducted to screen cultivars of sweet potato against sweet potato feathery mottle virus (SPFMV) infection. The treatments consisted of five cultivars coded as CV1, CV2, CV3, CV4 and CV5, respectively. The asymptomatic experimental plants were established, maintained under screen house conditions and graft-inoculated using infected vines which were tested SPFMV positive using both Double Antibody Sandwich Enzyme-Linked Immunosorbent Assay (DAS-ELISA) and Polymerase Chain Reaction (PCR). The experiment was laid out in Completely Randomized Design (CRD) and replicated three times. Results obtained from disease incidence and symptom severity indicated that there was significant difference (P &lt;0.05) among cultivars in their reaction to SPFMV infection. CV2 had the highest mean disease incidence (60.67%) while, CV3 had the lowest mean disease incidence (36.67%). CV1, CV3, and CV5 have the same lowest mean symptom severity score of 2.00 while, CV2 had the highest mean severity score of 4.00. Based on the reaction of the cultivars after inoculation, it could be concluded that, all the cultivars screened were susceptible to SPFMV but CV1, CV3 and CV4 cultivars have some degree of resistance to SPFMV infection and were therefore recommended for use by the farmers in the study area. This is the first research that screened sweet potato cultivars for resistance to SPFMV in Kebbi State, Nigeria

Mechanical Properties of Self-Compacting Concrete Subjected to Elevated Temperature

Self-compacting concrete flows and fills reinforcement gaps and corners of formworks without the need for vibration during the pouring process. The problem associated with the production of self-compacting concreteis the use of a high dosage of cement which necessitates the addition of supplementary cementitious materials to curtail this effect. As a result, the impact of a ternary blended pozzolanic materials on the mechanical properties of SCC exposed to extreme temperatures was investigated. A quantitative research approach was employed and an experimental design method was adopted. The materials used were cement, rice husk ash, metakaolin, and pulverized burnt bricks. Laboratory tests conducted at the hardened stage were compressive strength, weight loss, and ultrasonic pulse velocity of self-compacting concretesubjected to 200°C, 400°C, 600°C, and 800°C elevated temperatures. At 800°C elevated temperature, the result of residual compressive strength shows that SCC produced withaddition of the ternary blend at 10% had a higher value of residual compressive strength of 27.3% over the control specimens. Control specimens were found to have the least values of weight loss in comparisonto the self-compacting concreteproduced with the addition of the ternary blend. The result of residual UPV shows that self-compacting concrete produced withaddition of the ternary blend at 10% had a higher value of 8.6%over the control specimens. When self-compacting concreteis to be produced with a ternary blend of rice husk ash, metakaolin, and pulverized burnt bricksand subjected to an elevated temperature of up to 800°C, 10wt.% is the optimum cement replacementleve
