“…Nevertheless, these wastes could also contain a lot of valuable resources in the form of nitrogen, phosphorus, potassium, methane and other chemicals which might be useful [1]. The search for better life and socio-economic activities contributes to generation of these wastes from different sources, which are either classified as solid or liquid [2].…”

Polystyrene is extensively used in building and construction industry, packaging and transportation of fragile equipment due its low density, high melting point, low thermal conductivity, low water absorption, etc. Polystyrene after usage is usually discarded thereby causing environmental problems. The post-usage of polystyrene has, therefore, been a subject of intense research in recent times. The aim of this work is to produce adhesive from polystyrene wastes. Polystyrene waste (PS) was collected, processed and dissolved in tackifyer and formulated with diphnyle amine and diethylene glycol dibenzoate additives to produce adhesive using 3 levels variables factors and 4 levels testing factors of design expert optimization software. The produced adhesive was further characterized for viscosity, pH, percentages solid and moisture contents for their response surfaces. The results showed that the best fit viscosity for each run was Run 1B> Run 5A > Run 5D> Run 5B>Run 4D based on the regression analysis and analysis of variance (ANOVA). The pH values obtained ranged from 4.0 to 6.3; percentage moisture content was in the order of Run 1B < 5A<4D<4B and percentage solid content was in the order of Run 1B<5A<4D. The best fitted adhesive was run 1B with 5.93 % moisture content; 5A has 7.57 % moisture content and 4D with 8.76% moisture content. The percentage solid content; Run 1B has 67.19 %, 5A has 68.16 % and 4D has 75.50 %. The produced adhesives were found within the standard range of adhesives used in production of particleboard.

“…[7] The greater percentage women respondents from the north west is in consonance with the result of the 2006 Nigerian national population census which showed the north west zone had the highest figure of population,17,516288. [24][25][26][27] The sample size of women selected from each zone was representative enough to reflect the true opinion of the entire women population in their respective zones.…”

Abstract:The concerns of children testing positive to HIV virus shortly after birth is alarming in developing countries. The study assessed the level of awareness of women about Mother To Child Transmission. (MTCT) in Nigeria. The study used secondary data from the National Demographic and Health Survey (NDHS) conducted in the six geopolitical zones of Nigeria. The National Demographic Health Survey is one of the most comprehensive Nigerian datasets that contains extensive information on the reproductive health of women between ages 15 -49 years and therefore provides a unique opportunity to study the knowledge of women in the reproductive age group in the country. The 2008 Nigerian NDHS survey sample was made up of 33,385 women of reproductive age group from the six geopolitical zones. The data set was obtained from already analyzed results of the NDHS 2008. The results were summarized into tables and charts using Microsoft excel. Most women interviewed for the study were from the north west zone (24%) out of the six geopolitical zones in Nigeria. Twelve percent of the respondents were from the south east zone. Respondents from the south east zone reported highest awareness about the fact that HIV could be transmitted through breastfeeding to the child, (70.1%), while respondents from north west demonstrated least awareness that HIV could be transmitted through breastfeeding to the child. About 51.5% of pregnant women among the respondents reported adequate knowledge that HIV could be transmitted by breastfeeding while 28.6% were aware that the risk of MTCT could be reduced through the use of anti-retroviral drugs and 26.1% were aware that HIV could be transmitted by breastfeeding and the risk of MTCT could be reduced by taking anti-retroviral drugs. Most women do not have adequate awareness of mother to child transmission of HIV in the six geopolitical zones of Nigeria.

“…The major difference between the photoheterotrophic and mixotrophic cultivation conditions is energy source; while in mixotrophic cultivation organic compounds are used as an energy source, both light and organic compounds are needed in phototrophic cultivation. However, the production of several light-regulated metabolites can be enhanced under photoheterotrophic cultivation conditions [46]. Table 2 shows types of cultivation modes, which are suitable for different strains of algae, giving optimum productivity of lipid.…”

Food Industries Wastewater Recycling for Biodiesel Production through Microalgal Remediation

This article is an overview of a biosystem of food-industry wastewater (WW) treatment using microalgae towards circular bioeconomy through biosynthesis of compounds of added-value. Focusing on circular bioeconomy with concern to environmental pollution, the management of water-resource and energy-crisis could be combined; by upgrading conventional WW treatment and simultaneously producing a renewable and sustainable source of energy algal-lipids for biodiesel production. Phyco-remediation of food WW using microalgae has revealed many advantages that can fulfill new demands for the WW treatment. WWs can be valuable resources of micronutrients and organic content (carbon source) for algal cultivation. In this review, prospective routes for the production of value-added compounds (polysaccharides, amino acids, biofuels, and biopigments) along with the bioremediation of food industry WW have been discussed. Furthermore, limitations and issues of phyco-remediation of WW using microalgae have also been reviewed with perspectives for further research and development.
