This paper reported the socio economic importance and marketing of P. osun in Ibadan South West Local Government, Oyo State, Nigeria. Data were collected through the use of structured Questionnaire administered to 150 respondents. Descriptive statistics, Cost and return, and the cost-benefit ratio were determined while Gini coefficient was used to analyze the market structure. The result showed that 73.8% of the respondents were female while 46-55years were 34.7%. P. osun’s leaves were used in the treatment of skin diseases while its roots and bark were used in the treatment of asthma, traditional soaps/antibacterial, its timber is also used in furniture making and building construction. The study further revealed that Bode market has the highest Net profit (?96,319:98) while Beere market has the lowest Net profit (?33,303:18) and the sawmills amassed an average Net profit of (?5,389,625.00) per annum. The Gini coefficient (G=0.81) (G=0.71) for the P. osun herb sellers and P. osun timber sellers respectively indicates the market is highly monopolized and has minimal competition while the regression analysis revealed that age of the sellers and their religion are factors that influence the profit of P. osun sellers in the study area It can be concluded that P. osun trade is highly lucrative whereby an increase in capital will bring an increase in the quantity of P. osun and a sharp increase in profit made from this enterprise. There is the need to properly create awareness campaigns and educate the people about the economic values of P. osun which also require adequate management and conservation for sustainable utilization.

This work studies the experimental approach employed in performance investigation of thermoelectric materials using Orthorhombic Tin Sulphide (SnS) crystals as a case study. The sample material was joined with Lead Telluride (PbTe) to form a closed couple in the module. The two junctions of the couples where held at different sets of temperature causing varying sets of temperature gradients with 30°C/m difference between each set. The result obtained reveals that SnS and PbTe module has a high thermoelectric conversion efficiency which ranges from 1.92% to 4.84% for the range of temperature gradient of 60°C/m to 180°C/m. These ranges of thermoelectric conversion efficiency are better than those of commercial thermoelectric modules which has efficiencies of between 0.5% to 1%. It is also seen that SnS module can operate as both low and high temperature thermoelectric material.

Carbon dioxide is thought to be one of the contributing factors in the rise of global warming. Consequently the discovery for an efficient and economically valuable gas capturing system is highly in demand. Therefore there have been various recent developments in creating new, efficient and adaptable gas capturing materials. Microporous organic based materials received great research efforts in the field of environmental related applications such as gas storage and separations due to their permanent porosity, low density (i.e. composed of light weight elements) and remarkable physicochemical stability. Three anthracene microporous polymers (AMPs)1,2 bridged by imide links were successfully prepared by conventional nucleophilic substitution reaction between different 9,10-dihydro-9,10-ethanoanthracenes and 2,3,5,6-tetrachlorophalonitrile (instead of fluoro-monomer)2. AMPs display a BET surface area in the range of 711-796 m2 g–1, and adsorb reach to 1.70 wt. % H2 at 1.09 bar/77 K. The enhanced microporosity, in comparison to other organic microporous polymers originates from the macromolecular shape of framework, as dictated by the anthracene units, which helps to reduce intermolecular contact between the extended planar struts of the rigid framework. The impressive hydrogen adsorption capture of these materials verified by Horvath?Kawazoe (HK) and NLDFT analyses of low-pressure nitrogen adsorption data, which expected to be use in transportation as a source of green chemistry. A novel synthesis method for AMPs was done by Flow Injection System (FIS). This method has the advantage over conventional synthesis method as saving time-solvent and lowering synthesis cost of. Optimizing conditions (sample & reagent volumes, 0.1 ml/min flow rate, with 0.5 m coil length and 0.5 mm i.d) were used for increasing percentage yield of the product.

This paper contemplates a single vendor single buyer integrated production inventory problem with stochastic demand and transportation cost. Instead of constant lead time, it is assumed to be proportional to the size of vendor’s batch in each cycle. That is, lead time is composed of a lot size dependent run time and constant delay times such as moving, waiting and setup times. Transportation takes a crucial part in the manipulation of supply chain. The operation of transportation determines the efficiency of moving products. The problem is to find the number of shipments m, shipment size Q, safety factor k and the reorder point r. The objective is to minimize the joint total relevant cost incurred in the supply chain. A solution procedure is mentioned for solving the proposed model. Finally a numerical example is provided to illustrate the proposed model.

Healthcare sector in Malaysia has developed progressively since the early 1990s and was recognized under the Tenth Malaysia Plan (2011-2015) as one of the National Key Economic Areas, or NKEA The introduction of the Eleventh Malaysia Plan has supported this; it places focus on transforming the service sector, giving attention to private healthcare by improving the quality of service and increasing its global competitiveness. However, private healthcare poses a variety of challenges due increasing private healthcare spending, and thus affected the sustainability in the healthcare system. Moreover, sustainability issues are related to increasing costs that lead to waste. In this regard, it was suggested that lean healthcare should be applied in private hospitals and incorporated with sustainability, and needs to be carefully planned to ensure that it is feasible and sustainable in the long run. From previous studies, it is apparent that not many empirical researches have been conducted that pertain to the relationship lean healthcare practices (operational aspects and sociotechnical aspects) and sustainability. Therefore, the main objective of this research is to evaluate does the lean healthcare practices will lead to sustainability based on the triple bottom line; financial, social and environment. Besides, the article will embrace introduction, problem statement, literature review, methodology and conclusion. Finally, it is hoped this research will be extremely insightful for the service sector, specifically from healthcare organizations that are looking into improving their organizational performance and be much more sustainable.

Studied have established the prevalence of Vaginal Candidiasis (Moniliasis) from women attending antenatal care clinic at the Aminu Kano Teaching Hospital Kano. The Antimycotic susceptibility profile has not been reported. To study the Antimycotic susceptibility profiles of some Candida species isolated from suspected patients. Seventeen isolates of Candida species isolated from vaginal swabs were subjected to Germ Tube Test (GTT) for identification of Candida albicans. Four antifungal drugs were tested against the isolates to determine their Minimum Inhibitory Concentration (MIC) on the isolates using tube dilution method. Miconazole had the least MIC of 0.15 mg against 41.2% of the isolates. The MIC of Ketoconazole was 0.078 against 35.3% of the isolates. Up to 29.40% of the isolates were inhibited by Nystatin and Clotrimazole at MIC of 19.53IU and 0.093mg respectively. Miconazole has more antifungal activity against Candida albicans isolates at the area of study.
