The development of super Oxide by mitochondria is highly dependent on the mitochondrial respiratory chain, and cytochrome C acetylation by mitochondrial cytochrome oxidase and NASH-or succinate-dependent cytochrome c reductase direct reduction are thought to prevent the reoxidation. Ubiquinone is thought to be one of the main superoxide producers as the depletion of endogenous ubiquinone led to decreased hydrogen peroxide formation. free radicals have been involved in apoptosis as essential modulators, while experiments conducted under hypoxic conditions indicated that there may be apoptosis in their absence. Different stimuli are caused by various apoptotic pathways and in different ways, reactive oxygen species can influence them. The transcriptional activation of redoxrelated genes and reactive oxygen species and degradation of withochondrial oxidative ingredients leading to cell death, was proposed as characteristic of gene-induced apoptosis.

Tomato is one of the most important staple fruits in Nigeria that provides essential nutrients for maintaining good health and curing nutritional disorders. Tomato production has been facing serious challenges to its sustenance due to economic loss resulting from spoilage by microorganisms which makes its storage and transportation difficult. In this study, isolation and identification of bacterial associated with the spoilage of tomato fruits were carryout using standard laboratory procedures. Tomato samples were collected from Dundaye, Gidan Siminti and Asare Fadama’s, thus, major Fadama’s that supply tomato in Sokoto metropolis. Bacterial isolated were characterized and identified base on colonial, microscopic and biochemical test. The Bacterial counts of the tomato cultivars showed that DanEka has the highest bacterial counts of 5.39CFU/g, UTC 4.56CFU/g and Bahaushe 4.26CFU/g respectively. Results of biochemical test of isolated bacteria showed that two (2) species of bacteria were isolated in DanEka namely: Entrobacter cancerogenus and Bacillus coagulance, E. cancerogenus is the most frequent species that was isolated. Bahaushe cultivar was found to be infected by four (4) different species of bacteria namely Staphylococcus carnosus, Pseudomons trivialis Enterococcus casseli flavus and Raoutella terrgena. Also four (4) different species were also isolated from UTC namely Morganella morganii, Bacillus mycoides, Erwinia mallotivora, and Burkhoderia glumae. The findings showed that Bahaushe and UTC culitars were more susceptible to bacterial spoilage than DanEka. Researchers recommends precautionary measure of handling postharvest tomato fruits such as proper sanitary conditions, treatment with antimicrobial agents (chlorinated water) and refrigeration are necessary not only in reducing microbial toxins to human health, but also enhanced the fruits’ shelf-life, there is also need to develop spoilage-resistant cultivars for effective prevention and control of tomato fruits spoilage.

For the purpose of this study, a continuous dynamical system of ordinary differential equations of first order that are non-linear has been used to model the data precision of ecological species. Data precision is useful in selection of data for research purposes. Ordinary Differential Equation 45 (ODE45) numerical method has been applied to show the effect of decreased variations of the initial condition on data precision. The study creates awareness on the application of data precision in ecology and enlightens experts on the effects of varying initial condition parameter values on data precision of interacting ecological species. It was observed that 5% variation of the initial value conditions together gave a very low data precision value for y- data set which indicates best fit data. The results also show that y-data set is a better data set compared to x-data set and can be used for further research studies.

ASSESSMENT OF SPECIES COMPOSITION AND ABUNDANCE OF THE ICHTHYOFAUNA OF IKERE GORGE DAM, ISEYIN, NIGERIA.
Nigerian institute for oceanography and marine research, no.3, Wilmot point, Victoria Island, Lagos, Nigeria.
Accurate data collection is most difficult for inland fisheries like Ikere because of the artisanal nature and the rural location of the fisher folks and the rivers. Species composition and abundance studies were conducted at three sampling points (SP) based on hydrological characteristics of the dam. The wider and deepest part of the main Dam was designated, SP-A, the broad mid part as SP-B and the narrow shallow upper (inlet) as SP-C. Nine passive graded experimental gill nets (mesh sizes 25.4mm to 177.8mm) measuring 30 meters in length and 3 meters depth each arranged randomly were used for catching fish from the shore; surface and bottom habitat. Eleven fish families consisting of thirty-three species were identified from experimental catch. Nine hundred and fifty-nine (959) fishes (850.09kg) was recorded the first year (yr1) and 6891fishes (1181.07kg), the second year (yr2). The mean weight of each fish was 0.3kg ±0.04kg. Nine (9) families were recorded along the shore, seven (7) from the surface and ten (10) from the bottom.

Classification is a techniques used for solving problems. Several problems are solved with this technique. Gender classification is gaining grounds due to different areas of applications such as surveillance, security and monitory etc. Different authors have presented different research areas in the domain of gender classification and used several methods for analysing facial images in other to predict or classify the images. These methods adopted are either traditional algorithms, hybridised techniques or neural network so as to obtain better accuracy and reliability. We know that successful classification needs a robust method with good experimental setups that is why we present a gender classification using Convolutional Neural Network (ConvNet) for the purpose of reliability and accuracy using a local dataset. Although, majority of works done on this research area made use of the popular datasets such as FERET, AT & T, FACE94, AR to mention but few and/or compare two or more datasets to know the one with the best performance accuracy. Our state of heart method was used on local data set where sizable numbers of images were captured and five different augmentations were done on the images. The experimental result showed that our proposed ConvNet on our local dataset improve gender classification accuracy with the Precision (%) – 89.6276-; Recall (%) – 89.6276; Accuracy (%) – 92.8094 and F1-score (%) – 89.6237.

Plastics have woven their way into our daily lives and now pose a tremendous threat to the environment. Over a 100million tones of plastics are produced annually worldwide, and the used products have become a common feature at over flowing bins and landfills. Though work has been done to make futuristic biodegradable plastics, there have not been many conclusive steps towards cleaning up the existing problem. Here, the process of converting waste plastic into value added fuels is explained as a viable solution for recycling of plastics. Thus two universal problems such as problems of waste plastic and problems of fuel shortage are being tackled simultaneously. In this study, plastic wastes (low density polyethylene)were used for the pyrolysis to get fuel oil that has the same physical properties as the fuels like petrol, diesel etc. Pyrolysis runs without oxygen and in high temperature of about 300°C which is why a reactor was fabricated to provide the required temperature for the reaction. The waste plastics are subjected to depolymerisation, pyrolysis, thermal cracking and distillation to obtain different value added fuels such as petrol, kerosene, and diesel, lube oil etc. Converting waste plastics into fuel hold great promise for both the environmental and economic scenarios. Thus, the process of converting plastics to fuel has now turned the problems into an opportunity to make wealth from waste. The hazards of plastic waste are well known to us. The conversion of oil from plastic has dual benefits. First of all the oil produced can be used as a fuel for domestic purposes and also in vehicles and industries when further refined. Secondly the various types of pollution caused due to waste plastics can be minimized. Plastic in the first place is manufactured from natural gas specifically from ethane which is a constituent of natural gas. Therefore the waste plastic can be converted back into it. For the process of conversion a machine can be used which will heat the plastic to a temperature so that it melts and does not burns.

Oil and gas wells are conditions to maintain the reservoir pressures and to avoid unwanted exit of hydrocarbons. The Norwegian petroleum safety regulations desire that a multi-barrier constructions be made for reservoir. This principle guaranty that the next barrier prevent escalating occurrence should the other protection fail. A subsea wellhead is a strong and heavy walled pressure barrier at the top of the well on the sea bottom. It is the second pressure barrier during drilling and exploration of oil and gas. The Blow out Preventer (BOP) is position on top of the wellheads while the drilling riser connect between the FPSO and the BOP. Tidal waves and current interfered with the riser that result in dynamic movement, causing localised bending stress. The wellheads is a load carrier supporting the riser to resist the static and cyclic forces acting on it. These forces: tensional and compressional causes fatigue failure of the wellhead. This study provide a comprehensive professional qualification plan that guarantee a safe flow from subsea wellhead to Floating Production Storage and Offloading (FPSO) vessel operation in a deep or ultra-deep waters.

In wireless sensor network, sensor nodes are furnished with non-chargeable, low power, and irreplaceable battery source, and their lifecycle depends on these batteries. Consequently, these nodes consumed more energy while conveying their sensitive data to the desire destination, thus, sensor nodes may exhaust their energy after separate rounds of operation. LEACH Protocol is the first and most popular energy-efficient clustering algorithm for WSNs that was proposed for reducing power consumption. LEACH is a Clustering-based routing protocol which are cost-effective in terms of energy, scalability, fault tolerance, reduce latency, and decreases communication in WSNs. In LEACH, energy is preserved by splitting the network period into smaller groups referred to as a cluster and altering the character of the sensor node as “Cluster leaders” and as a ” node members” in each round; thus, helps to dispenses energy amid all the nodes. The cluster leaders are accountable for data collection, accumulate data, afterwards diffuses the accumulated data Also, direct communication is used by each cluster head (CH) to forward the accumulated data to the base station (BS). However, the downside of LEACH is the unequal dispersal of nodes in different clusters. In addition, the residual energy of the sensors was not taken into consideration during the selection of cluster head in LEACH. Consequently, nodes with minimum residual energy may be designated as Cluster heads and could result in the early death of the nodes; this will also lead to failure of the network. Due to the drawback of LEACH, much research has been done to enhance LEACH for better routing and clustering approaches. Therefore, in this paper, we reimplement LEACH and ILEACH protocols and perform a set of simulations testing that have been used to improve network lifetime and minimize energy consumption of sensor nodes in WSN. The simulation was administered using MATLAB R2018b Additionally, we compared the performance of LEACH and ILEACH using two metrics, namely the network lifetime and network throughput and the result shows that the ILEACH protocol outperforms the LEACH protocols.

The paper impact of teleconferencing technology in Nigerian colleges of education review indicates that the focus of most of the studies has been to assess teleconferencing as a medium for education and training along diversification such as interactivity factors influencing effectiveness in teaching-learning, role of teachers/resource person etc. there are hardly any studies on the perceptions of teachers who use this type of technology. The present study focuses on teachers’ views, their opinions experiences and account of teleconference as a teaching tool. Specifically, the study was conducted to achieve two major objectives viz: to explore the teachers’ perceptions of the technology especially with regard to the learning objectives, appropriateness, flexibility, interactivity of use, etc. in higher learning situations, as well as analyses some ‘good’ and ‘bad’ practice that may have been followed during the course of teleconferencing so that these can serve as useful experiences for others in the system to emulate or avoid. To achieve the above objectives, descriptive survey research design was adopted using the simple random sampling techniques among the 50 educators and learners available in the case study. Questionnaire was utilized for data collection and data collected were analyzed using simple percentage. It was discovered from the findings of the study that teleconferencing can enhance collaborative learning in education and that limited access to technological equipment was the greatest challenge to educators in deploying teleconferencing as to support distance learning. Therefore, the study recommends that government should make provision for computer system and teleconference technology equipment to the various schools in order to encourage and educate teachers and learners.
