Background: Propolis is a bee (Apis mellifera) product of plant origin with varied chemical composition depending on the ecology of the botanical origin. It has been reported in literature to possess various therapeutic effects both traditionally, clinical trial, and animal study. Objectives: In the present study bioactive principle in methanol extract of Nigerian bee (A. mellifera) propolis was determined by gas chromatography-mass spectrometry (GC/MS) study. Materials and Methods: The methanol extract of Nigerian bee (A. mellifera) propolis was characterized for its chemical composition by preliminary phytochemicals screening and GC/MS analysis using standard procedures and methods. Results: Phytochemical screening revealed the presence of flavonoids, saponins, alkaloids, tannins, cardiac glycosides, anthraquinones phlobatannins, and steroids while GC/MS chromatogram revealed nineteen peaks representing 60 different chemical compounds. The first compounds identified with less retention time (RT) (13.33s) were methyl tetradecanoate, tridecanoic acid, methyl ester, decanoic acid, methyl ester while squalene, all-trans-squalene, 2,6,10-dodecatrien- 1-ol, 3,7,11-trimethyl-, (E,E)- and farnesol isomer a took longest RT (23.647s) to identify. Methyl 14-methylpentadecanoate, hexadecanoic acid methyl ester, methyl isoheptadecanoate, and methyl tridecanoate were the most concentrated constituent as revealed by there peak height (26.01%) while eicosanoic acid was the least concentrated (peak height 0.81%) constituent of Nigerian bee propolis. Conclusion: The presence of these chemical principles is an indication that methanol extract of Nigeria bee propolis, if properly screened could yield a drug of pharmaceutical importance. © SAGEYA.

It is certain that Space Education is very important for sustainable space development especially in the underdeveloped country like Nigeria and as children is going to bear new era of space development. This project was done to ignite the curious mind of high school children in the rural areas in Space Education and Technology development. The European nation has recently focused on space education for the young generation to enhance sustainable space development, however; our country as a developing country does not consider investing in the children the basic knowledge of space technology and astronomy. Even the attempts made by the National Space Research and Development Agency to involve young children into space was only focused in the Federal Capital Territory Abuja, Where there was already Modern High Schools that are highly equipped. This project bridged the gap in opportunities available in the rural to urban areas. This project enhanced basic science education in the rural areas and build the space development program thus, achieving the mission of He Space Children Foundation. The targeted objectives was to carry out space education outreach sensitization to the high schools in 3 rural communities and equipped the schools visited with standard space science equipment's. Introduced the students to Universe in a box to enhance the study of the universe, and to initiate a team project on space and astronomy among young students. Thus over 1,610 high school students was involved. The project also focused on Teacher's re-training by holding workshops within the Local Communities and over 200 Science Teachers turned up in the first workshop and sensitization in 2015. It was observed that most of teachers realized space can be applied not only for astronomy but also in various subjects. Although, most of teachers do not have enough time for investigating or preparing teaching materials as they have to put lots of effort to extracurricular activities held after school and weekends (like farm practice). It is necessary for the government to study and analyze more about present issues on educational field and to build effective infrastructure to spread space education based on demands. I believe that mysteries of space can stir up children's 3 spirits ("Curiosity", "Adventurous" and "Craftsman-ship"). It is my most important mission to motivate young students via space education at their early stage of school life. As part of my personal volunteered Community Development Service during my National Service.

Internet as a dependent provider repository of saved information and resources is challenged through the request for heterogeneous content. This necessitated the need to lodge and save services and resources on different root servers. However, the semantics of the current Internet have given concern to Users diversifying their interest towards media driven data. These, along several issues generated the need for a new paradigm shift known as Information-centric networks. It has thus been submitted along its advantages, but predictor issues include excessive caching of similar contents resulting to low diversity on the entire network. This study used a mathematical formulation of graph-theory to palliate the aforementioned issue to improve the diversity of contents. The results obtained show our submitted PRECache approach outperformed the default approach to the mark of 80% against 20% and 49% for LCE and ProbCache respectively as the cache sizes varied. © 2017 American Scientific Publishers All rights reserved.

The study investigated the effect of sublethal concentrations (39.10mg l-1, 19.55mg l-1, 9.87mg l-1and 0.00mg l-1) of Portland cement powder in solution on the biochemical parameters (cholesterol, triglyceride, total protein, glucose, lactate dehydrogenase and creatine kinase) in the serum, liver and kidney of the juvenile African catfish Clarias gariepinus after a fifteen-day exposure period. The result revealed varying levels of significant difference in serum, liver and kidney cholesterol, triglyceride, total protein, glucose, lactate dehydrogenase and creatine kinase activities, showing that the liver was most affected, the serum was less affected and the kidneys were least affected by the sublethal concentrations of the Portland cement powder in solution after the fifteen-day exposure period. Consequently, the liver and kidney, the medium of transportation of nutrients and other metabolites were affected. The liver and kidney, which are primarily responsible for maintaining external and internal milieu of fishes via detoxification, metabolism and excretion, are susceptible to deleterious effects of Portland cement powder. Therefore, sublethal concentration (39.10mg l-1) of Portland cement powder in solution after a fifteen-day exposure has been most toxic and debilitating to the test fish. © Royal Irish Academy.

A two-year study was conducted on maize (Zea mays L.) at the University of Ilorin Teaching and Research Farm Ilorin, Nigeria, during 2005 and 2006 growing seasons. The objective was to investigate correlation between grain yield and other agronomic parameters using 10 open-pollinated maize varieties and their 45 F1 hybrids in a half diallel. Positive and significant phenotypic and genotypic correlations were found for days to 50% tasselling with plant and ear height, and grain yield with plant height, number of grains ear-1 and ear weight. Positive and significant environmental correlation was also recorded for grain yield with plant and ear height, and ear weight. The path analysis revealed that, days to 50% silking, ear weight and number of grains ear-1 had the highest direct effect on grain yield, while number of grains ear-1 had the highest moderate indirect negative effects on grain yield. Days to flowering, plant and ear height, number of grains ear-1 and ear weight could be the important selection criteria in improving open pollinated maize varieties and hybrids for high grain yield. © 2010 Academic Journals.

Biofilms are sessile communities of microorganisms growing on material surfaces and embedded in self-accumulated extracellular polymers. A comprehensive analysis of physical, chemical and biological factors including hydrodynamic and nutrient conditions that regulate their formation is required to adequately gain insight to this complex multicellular microbial life style. Reproducible experimental models that consider all the conditions under which they grow and develop also remain a required tool for studying the biofilms. As a result of its ability to create hydrodynamic and nutrient conditions coupled with continuous and non-destructive ability to grow biofilms, flow cell technology has become one of the most recently patronised models used to study microbial biofilms. This article focuses on recent advancements, principles and practical application of flow cell technology to study microbial biofilms. © 2016 Penerbit UTM Press. All rights reserved.

The nutritionists' interest in leaf vegetables including Hibiscus sabdariffa stems from their rich contents of essential amino acids, vitamins and minerals which are needed for normal metabolic activities of the body. Vegetables are also good sources of dietary fibres that are important for bowel movement. However, the presence of some inherent anti nutrients and toxic substances in vegetables has been a major obstacle in harnessing the full nutritional benefits. It is against this background that this research was conducted to determine the effect of some processing methods on the antinutrients (soluble and total oxalates), toxic substances (cyanide and nitrate) and some micronutrients which include vitamin C, P-carotene (provitamin A) and mineral elements (Fe, Mg, Zn, Na and K) in Hibiscus sabdariffa. The processing methods include boiling (vegetable leaves were boiled in distilled water for 5 and 10 min) and sun drying. Results obtained showed that the cyanide, nitrate and soluble contents in fresh vegetable sample are within the tolerable level and they can be well tolerated in the meals. However, the total oxalate content in the vegetable is high enough to induce oxalate toxicosis. All the processing methods significantly (p<0.05) reduced the antinutrients and toxic substances in Hibiscus sabdariffa except that the reduction in soluble and total oxalate with sun drying was not significant (p>0.05). Boiling methods reduced these toxic substances significantly (p<0.05) more than sun drying. The antinutrients and toxic substances generally decreased with boiling time. These post-harvest treatments also reduced vitamin C content significantly (p<0.05) in Hibiscus sabdariffa. Boiling method retained more of the vitamin compared to sun drying. P-carotene levels increased in the boiled vegetable leaves, while its content was reduced in sundried leaves. However, boiling beyond 5 min led to significant (p<0.05) reduction of P-carotene levels in the vegetable. Mineral elements (Fe, Cu, Mg, Na and K) decreased significantly (p<0.05) with boiling in Hibiscus sabdariffa; however sun drying had no significant effect on the mineral contents. The result concludes that moderate boiling significantly reduces the levels of antinutrients and toxic substances while still conserve some micronutrients in amounts sufficient to meet our dietary requirements. © 2012 Academic Journals Inc.

Nigeria is in the advanced development stages of extracting its oil sands resources to boost national revenue and economic prosperity, like other countries in Sub-Saharan Africa including the Republic of Congo and Madagascar. Compared to resource-rich developed countries like Canada and America, the consequences of oil sands extraction is likely to be disastrous in countries like Nigeria that have a poor reputation for managing resources (as is the case with the petroleum sector). Using a mixed-method approach-focus group discussions, interviews and observations-this paper addresses environmental concerns about oil sands extraction in Nigeria. Overall, the communities perceived oil sands development negatively, because of fears of loss of communal lands, biodiversity, water availability and quality, and pollution. They were angry with the previous administrations over the lack of communication, and were deprived of socio-economic opportunities and pollution from prolonged delays in oil sands extraction. The way forward is to form sustainable partnerships between the government, communities, industry and other stakeholders to achieve responsible oil sands development-environmentally friendly development that meets climate obligations, addresses cumulative impacts, and acts in the best interest of host communities and Nigerians. © 2015 Department of Geography, National University of Singapore and Wiley Publishing Asia Pty Ltd.

Instrumental neutron activation analysis was used for multi-trace elemental determination of six medicinal plants: Boerhavia diffusa, Euphoria hirta, Senna occidentalis, Senna obtusofolia, Cyprus dilatatus and Mitracarpus villosu. These plants were irradiated in the Nigeria Research reactor-1, at flux levels of 2.25E+11ncm -2s -1 in the outer channel and 5.0E+11ncm -2s -1 in the inner channel. A total of the twenty one elemental concentrations were evaluated highlighted the similarity between the elements obtained for the six plants. It was found that Euphoria hirta and Senna occidentalis have similar concentrations of elements. Boerhavia difusa, Mitracarpus villosus, Cyprus dilatalus and Senna obttusifolia were also similar in elemental content to each other, while Boerhavia difusa was the only exceptional outlier. The accuracy of measurements was evaluated by analyzing IAEA-359 cabbage references standard materials and the results show good agreement with certified or literature values within ±0.01% to ±0.87%. © 2012 Elsevier Ltd.
