Effects of the combination of ketamine and medetomidine anaesthesia on haematological parameters in Sahel goats
The effects of the combination of ketamine and medetomidine intravenous (IV) anaesthesia on haematological parameters were evaluated in six sahel goats comprising of 5 females and 1 male with mean body weight of 19 ± 1.4kg. Each goat was given a recommended dose of the drugs combination: medetomidine at 0.01mg/kg and ketamine at 5mg/kg body weight IV. Pre injection blood samples were obtained and at 15 minutes interval during anaesthesia in EDTA bottles and later analyzed. The parameters evaluated were packed cell volume (PCV), haemoglobin concentration (Hb), red blood cells (RBC), white blood cells (WBC), and differential leucocytes (neutrophils, eosinophils, basophils, lymphocytes and monocytes). The ketamine-medetomidine combination produced a significant decrease in PCV values from 30 minutes (24.00±1.23%) to 90 minutes (25.00±2.55%) compared with baseline value (29.50±1.52%); Hb also decreased significantly at 45mins. RBC and WBC values showed no significant difference compared with baseline values. Neutrophils decreased significantly at 45mins (35.17±3.25) compared to baseline value (41.50±3.67). There were no significant differences in lymphocytes, monocytes, and eosinophils values from baseline. The ketamine and medetomidine combination produced decreases in PCV, Hb and neutrophils. The goats recovered from anaesthesia uneventfully.Keywords: Anaesthesia, Goats, Haematology, Ketamine, Medetomidine

Comparative Study of the Nutrient Composition of Millet and Maize-Based Complementary Weaning Foods
Children in the study area are mostly weaned on cereal gruel that is deficient in some essential nutrients. The current work compared the nutrient composition of millet (MLMX) and the (MZMX) based complementary food prepared from locally sourced food stuffs. MZMX was formulated from maize, soyabeans, groundnuts, crayfish and palm oil. MLMX contained millet in place of maize. Proximate composition of the two diets, were not significantly different (p > 0.05) and compared well with frisocream. Mineral element composition of the two diets was significantly ( p < 0.05) different when compared. Amino acid compositions of the diets were comparable to that of frisocream. Antinutritional factors in the two diets were not significantly (p > 0.05) different when compared
Evaluation of the Hydraulic Conductivity of Compacted Laterite-Metakaolin Mixtures for Solid Waste Leachate Containment
This paper presents the results of a study conducted to investigate the benefits of using metakaolin (MK) with laterite as liner material for containment of municipal solid waste (MSW). Laboratory tests were conducted on laterite specimens treated with MK at concentrations of 0 - 20 % by weight of the soil and compacted using four types of compaction energies. Hydraulic conductivity was determined based on permeation of the compacted laterite - MK mixtures with deionized water (DW) and municipal solid waste leachate (MSWL), respectively. Deionized water was the reference permeant fluid. The results showed that hydraulic conductivity generally decreased with increase in the percentage addition of MK to the soil. From an economic and sustainability point of view, it has been found from the results that 5 % MK can be added to soil and compacted at moulding water content of 14.1 % using the West African Standard (WAS) compaction energy to achieve the regulatory hydraulic conductivity of less than or equal to 1 x 10-9 m/s for compacted soil liner. The natural logarithm of the hydraulic conductivity experimental results were computed and used to develop regression equations for estimating hydraulic conductivity given MK contents and compaction energies. The results of the two-way analysis of variance (ANOVA) test carried out at 5 % level of significance showed that calculated F-statistics are statistically significant and the measured values of hydraulic conductivity compare well with the predicted values. The developed models can therefore be used to give good estimates of hydraulic conductivity of soils having similar properties with the laterite investigated in this study. Therefore, the developed models can be used to give good estimates of hydraulic conductivity of soils having similar properties with the laterite investigated in this study. Keywords Â_ Deionized water, Hydraulic conductivity, Leachate, Metakaolin, Municipal solid waste
Repositioning the Facilities in Technical College Workshops for Efficiency: A Case Study of North Central Nigeria
This article focuses on assessing the facilities in Government Technical College workshops in the context of a developing country. A descriptive survey design was adopted. Two research questions and a hypothesis were formulated to guide the study. A 35-item questionnaire was developed based on the National Board for Technical Education (NBTE) standards on Technical College workshops, and was validated by three experts. Data was collected from 101 administrators, 140 teachers, and 24 workshop personnel randomly sampled and stratified along trades in 19 Government Technical Colleges in North Central Nigeria. Mean was employed to answer the research questions while one-way analysis of variance (ANOVA) was employed to test the hypothesis using Statistical Package for Social Sciences (SPSS) for analysis. Results revealed that administrators, teachers, and workshop personnel shared similar views on inadequacy of facilities in Technical College workshops. It was therefore recommended that: The private sector should be encouraged to initiate and participate in the provision of facilities using such methods as build operate-and-transfer (BOT), build own-operate and transfer (BOOT) and rehabilitate-operate and transfer (ROT); special intervention funds should be set aside by Government for procurement of workshop facilities to technical colleges, such channels may include Education Tax Fund (ETF) as practiced in Nigeria; Non Governmental Organizations (NGOs), Parent Teacher Association (PTA), and Community Based Organizations (CBOs) should be asked for support in supplying relevant facilities to the workshops as obtained in some nations; and that a specific percentage of income tax generated annually by the Government should be utilized for provision of workshop facilities in technical colleges

The relationship between yield curve components and equity sectorial indices: Evidence from China
This paper examines the static and dynamic connectedness (returns and volatility) between the components of the sovereign yield curve (level, slope, curvature) and sectorial equity indices in China. We document a strong connection between these factors, particularly during three periods: the August 2011 stock market crash, the 2015 Chinese stock market crash and the 2018 US-China trade war. Our results show that the level component of the yield curve is a net transmitter of return spillovers, whereas the curvature component of the yield curve is a net transmitter of volatility spillovers. These findings may be useful for portfolio managers and policymakers making decisions regarding portfolio allocations, risk management, and monetary policy
Application of Stochastic Frontier Analysis in the Estimation of Allocative Efficiency of Part-time Food Crop Farmers in Kogi State, Nigeria
In this paper, stochastic frontier cost model is used to analyze the allocative efficiency of part-time food crop farmers in Idah Local Government Area of Kogi State, North Central Nigeria and also to establish the socio-economic factors that determine allocative efficiency. It is evident from the study that part-time food crop farmers are not fully efficient in their allocation of production resources. This was confirmed by the presence of allocative inefficiency effects in part-time food crop farming with average allocative efficiency of 97.95 %. The study also revealed that rising age and household size contribute to allocative inefficiency in part-time food crop farming, while level of education and farming experience were found to increase allocative efficiency among the part-time food crop farmers. It is recommended that policies aimed at encouraging relatively younger and educated persons and providing them easy access to improved seeds and fertilizers should be formulated .This will go a long way in enhancing allocative efficiency in part-time food crop farming. Keywords: Part-time farming, stochastic frontier cost model, allocative efficienc
Network connectedness dynamics of the yield curve of G7 countries
Our study examines the connectedness between the sovereign bond yield curve components (Slope, Curvature and Level) of the Group of Seven (G7) countries. Using the framework of Nelson and Siegel we are able to track their connectedness over the long, medium and short-term horizons. The results of the static analysis show an increased connectedness in the long-term as compared to medium and short-term factors, whereas the results of dynamic analysis demonstrate three distinct phases of connectedness over time. Specifically, these phases are characterized by stable, decreasing and then increasing level of connectedness of the G7 system before, during and after the 2008 crisis, respectively. We also find France as well as Germany function as the net transmitters of shocks whereas UK and Japan function as the net receivers of the shocks for all the components of their yield curves. The findings may shed light on the dynamics and interaction of yield curve shocks between these major economies and may be essential for financial market participants such as investors, fund managers, and policy makers, which debt consists a part of their assets allocation
