Effects of NIOMR smoking kiln and oven on the crude protein, minerals and vitamins of catfish Clarias gariepinus

The effects of two different preservative methods, NIOMR Smoking Kiln and Oven drying on Crude Protein minerals and Vitamin of clarias gariepinus were studied. Clarias gariepinus were obtained from the fish farm of African Regional Aquaculture Centre, Aluu, Port Harcourt. The crude protein, minerals and vitamins of the fresh fish were determined immediately while two other batches were separately dried using oven at 50~'C for 30minutes and NIOMR Smoking Kiln at 70~'C for 3 hours. Result of the crude protien of fresh fish was 21.84 ~c 1.10 which increased to 59.53 ~c 1.88 and 35.41 ~c 1.00 in both NIOMR smoking and oven, respectively. This means that, there was a significant different in both dryers on the crude protein. This will improve the knowledge and capacity of rural women and agricultural communities on the appropriate processing method for fish. The mineral and vitamins of oven dried and NIOMR Smoking kiln were analyzed. The vitamin content of both the fish, dried and smoking kiln shows no significant different except in vitamin A which was significant (p<0.05).There was significant different (p<0.05) in the mineral content of the two different drying method except in sodium, Potassium and Phosphorus of the drying method. This result indicates that the two drying methods have effects on the nutritional quality of catfish

Time of introducing component crop influences productivity of intercropping system

Field experiment was conducted at National Horticultural Research Institute (NIHORT), Mbato Sub-station, Okigwe, Imo State, South-eastern Nigeria in the 2012 and 2013 cropping seasons to establish the most appropriate time to introduce component crops in cocoyam/cowpea mixture. Five different planting schemes (two and four weeks before, two and four weeks after and same day) and two cowpea genotypes (climbing Akidienu and erect IT97K-499-35) were used. The component crops were grown in monocultures to assess the productivity of the systems. The experimental design used was a completely randomized design with three replicates. Growth and yield of cocoyam and the cowpea genotypes increased significantly (P&lt;0.05) when either of the component crops was planted earlier than the other. Intercropping reduced significantly (P&lt;0.05) cocoyam yield by 0.7 − 74% in IT97K-499-35 and 22 − 80% in Akidienu. Sowing the cowpea genotypes the same day or before cocoyam resulted in over-yielding of cowpea, whereas sowing Akidienu and IT97K-499-35 after cocoyam caused pod yield reductions of 64% − 73% and 32% − 59% on average, respectively. Cocoyam planted two weeks before IT97K-499-35 produced more satisfactory yields of the intercrops than the other planting schedules with LER, LEC and ATER of 2.15, 1.03 and 1.57, respectively

Carcass, Organ Weights and Egg Quality Characteristics of Guinea Fowl Layers Fed Varying Levels of Butter Fly Pea Leaf (Centrosema Pubescent) Meal.

This study was conducted to investigate the effects of different protein levels on growth of guinea fowl keets (Numidia meagris) of the same age under intensive system in a typical poultry house from 6th week to 12th week of age. They were fed commercial broiler starter for two weeks and maintained on same diet of 18% crude protein for 5 weeks of age and given water ad libitum. The birds were separated into three pens. One hundred and twenty old guinea fowls were assigned at grower period on 3 dietary protein levels of 14, 16 and 18% crude protein (CP) on same metabolizable energy level of 2800 kcal/ kg. The study conducted at the Poultry Unit of Teaching and Research Farm, Imo State Polytechnic was used to test the performance of the guinea fowl layer birds. The birds were killed at the owner’s farm by cutting the neck through the jugular vein. There was significant difference (P&lt;0.05) in feed intake between the three treatments. The internal organs for the treatments were not significantly different. Keywords: Carcass, Organ Weights, Egg Quality Characteristics, Guinea Fowl Layers, Butter Fly Pea Leaf (Centrosema Pubescent) Meal

Using a novel climate-water conflict vulnerability index to capture double exposures in Lake Chad

Climate variability is amongst an array of threats facing agricultural livelihoods, with its effects unevenly distributed. With resource conflict being increasingly recognised as one significant outcome of climate variability and change, understanding the underlying drivers that shape differential vulnerabilities in areas that are double exposed to climate and conflict has great significance. Climate change vulnerability frameworks are rarely applied in water conflict research. This article presents a composite climate–water conflict vulnerability index based on a double exposure framework developed from advances in vulnerability and livelihood assessments. We apply the index to assess how the determinants of vulnerability can be useful in understanding climate variability and water conflict interactions and to establish how knowledge of the climate–conflict linked context can shape interventions to reduce vulnerability. We surveyed 240 resource users (farmers, fishermen and pastoralists) in seven villages on the southeastern shores of Lake Chad in the Republic of Chad to collect data on a range of exposure, sensitivity and adaptive capacity variables. Results suggest that pastoralists are more vulnerable in terms of climate-structured aggressive behaviour within a lake-based livelihoods context where all resource user groups show similar levels of exposure to climate variability. Our approach can be used to understand the human and environmental security components of vulnerability to climate change and to explore ways in which conflict-structured climate adaptation and climate-sensitive conflict management strategies can be integrated to reduce the vulnerability of populations in high-risk, conflict-prone environments

An Implementation of K-NN Classification Algorithm for Detecting Impersonators in Online Examination Environment

The online examination platforms also known as computer-based testing (CBT) platforms for conducting mass-driven examinations over computer networks to eliminate certain issues such as delay in marking, misplacement of scripts, monitoring, etc., associated with the conventional Pen and Paper Type (PPT) of examination have also been bedeviled with the issue of impersonation commonly associated with the PPT system. The existing online examination platforms rely on passive mechanisms such as the CCTV system and the human invigilators for monitoring the examination halls against cheating and impersonation. The proposed model integrates some level of intelligence into existing online examination prototype by designing and developing an intelligent agent service that could assess students against impersonation threat in an online examination environment using the K-Nearest Neighbor (K-NN) machine learning classification technique considering the level of accuracy and response time in answering the questions. A total of 3,083 dataset was downloaded from an online repository; 80% (2,466) of the dataset was used for training the model, while 20% (617) dataset was used in testing the model to enable the model detect unseen data correctly. Results showed that the developed model has a 99.99% accuracy rate, precision, recall and f-score

Preliminary Findings on Metastatic Brain Tumors in Enugu, Southeast Nigeria

Background: Metastatic brain tumors (MBTs) are the most common brain neoplasms seen clinically and are often associated with poor outcomes. This study highlights the demographic, clinical, and radiological profiles as well as outcomes of MBTs managed in a tertiary hospital in Southeast Nigeria. Methods: This was a 1-year prospective observational study of patients with MBT who presented to the neurosurgery unit of the University of Nigeria Teaching Hospital, Enugu, from December 2018 to November 2019. Data on the demography, clinical and radiological features, treatment, and outcomes were collected and analyzed. Results: Of the 31 patients with MBTs, 58.1% were female and 41.9% male. The mean age was 51.0 ± 15.2 years. The most common presenting features were limb weakness (77.4%), headache (58.1%), and personality changes (54.8%). About a quarter (26.7%) were fully conscious at&nbsp; presentation. Only 45.2% knew that they had a systemic malignancy (SM) before presentation. The breast (29.0%), lungs (22.6%), and skin (19.3%) were the common sources of metastases. The lesions were solitary in 25.8% and multiple in 74.2%. They were predominantly frontal (80.6%), with bilateral distribution in 64.5% of patients. Radiotherapy was done in 58.1% and surgery in 6.5% of patients. Prior knowledge of the existence of a SM (P = 0.045) and unilateral brain involvement (P = 0.013) were associated with better 30-day survival. Conclusion: The breast is the most common source of brain metastasis. Prior knowledge of the existence of a SM and unilateral brain involvement is associated with better short-term survival. Keywords: Brain, metastasis, primary, surviva

Effect of ethanolic extract of Justicia secunda (blood root) leaves on reproductive organs and hormones in female Wistar rats

Background: Several environmental chemicals are suspected to be responsible for adverse health effects on the reproductive system. Poisonous plants grow in most communities found on range lands and pastures. One major effect on consumption of these plants is on reproduction which includes birth defect, abortion and interference with Oogenesis, spermatogenesis, libido and estrous cycle. Justicia secunda (blood root) as the name implies is known for its anti-anemic properties.Methods: Animals were grouped into 6 groups with 6 rats in each group. They were housed in metal cages at room temperature and had access to commercial standard rodent pellets and clean water. Group 1 (control 0.00 mg/kg.) was given distilled water, groups 2-6 were given 99% ethanolic extract of Justicia secunda leaves orally at dose levels of 300, 400, 400, 450 and 450 mg/day, respectively for 42 days.Results: The result of this study indicates that ethanolic extract of Justicia secunda (blood root) was able to increase the level of FSH significantly at medium dose group. Significant increase in oestrogen level observed in this study.Conclusions: ethanolic extract of Justicia secunda (blood root) leaves is likely to cause an increase in the secreting ability of cells of the anterior pituitary gland producing FSH or cells of the hypothalamus producing gonadotrophin releasing hormones. The plant is likely to contain steroids

Investigating the mineral composition of proceessed cheese, soy and nunu milks consumed in Abuja and Keffi metropolises of Nigeria

Milk and its products are needed for proper body building. Processed cheese, nunu and soy milk consumed within Abuja and Keffi metropolises were analyzed for their mineral contents. X1, Y1, Z1 represents soy milk, nunu and cheese from Abuja metropolis while X2, Y2, Z2 represents sample from Keffi metropolis respectively. Calcium (265.53±0.25 mg/mL), iron (1.19±0.92 mg/mL), potassium (162.77±0.02 mg/mL) were found to be higher in cheese milk (Z1) from Abuja than that (225.82±0.13 mg/mL, 1.05±0.60mg/mL and 130.41±0.04 mg/mL) found in Keffi (Z2) examined respectively, though the amount of sodium present (151.0±0.08 mg/mL) in cheese (Z2) from Keffi is slightly higher than that (150.08±0.01 mg/mL) from Abuja (Z1). Also, Soya milk from Abuja (X1) had highest amount of zinc (0.76±0.00 mg/mL) while that of Keffi (X2) was 0.65±0.3 mg/mL, for magnesium and copper, higher values 18.40±010 mg/mL and 0.25±0.02 mg/mL were recorded for soy milk (X2) from Keffi while soy milk from Abuja (X1) had 17.97±0.20 mg/mL and 0.16±0.01 mg/mL respectively. Chromium was dictated in both cheese samples but not dictated in soya and nunu milks from both metropolises. It is seen from the investigation that cheese had more minerals followed by soya milk. Nunu milk sample had the least quantity of minerals; also all the samples analyzed have minerals present in them. Therefore, they are needed for the proper functioning of the body system Keywords: Analysis, Concentration, Milk, Mineral, Metropolis, Flame Atomic Absorption Spectroscop
