Four-armed star poly (ε-caprolactone) (PCL) terminated with carboxy group was prepared by two-step reaction. The carboxy group of star PCL was activated and chemically conjugated to the amine group of PLL (polylysine) to produce sPCL-b-PLL copolymer. The structure of final product and the intermediates were characterized by IR and 1H NMR. The sPCL-b-PLL copolymer can self-assemble into micelle in aqueous solution. The CMC (critical micelle concentration) of micelle ranged from 7.603 × 10-4 to 2.638 × 10-4 mg.mL-1 for different sPCL-b-PLL copolymer. In addition, Curcumin as a hydrophobic drug can be entrapped in the sPCL-b-PLL micelle. The results indicated that the micelle exhibited 9.431% loading capacity for Curcumin, and it can be used as a potential delivery carrier for the hydrophobic drug.

DOI: 10.9734/BJAST/2015/16536

Energy production is one of the significant challenges our world will face in the future. The utilization of fuels originating from plants as an alternative energy source will impact fossil fuel utilization and energy production. This research focuses on the hydrothermal treatment of hay biomass by analyzing the chemical oxygen demand (COD), which is a commonly used testing method to determine the amount of organic pollutants found in drinking or wastewater. The test indicates the mass of oxygen consumed per liter of solution, expressed in milligrams per liter (mg/L), also referred to as ppm. In this paper, COD tests were used to indirectly determine whether the yield of biogas in a biogas plant could be increased by pretreating the biomass (hay) with heat and/or decreasing the particle size. It was assumed that the potential space-time-yield of biogas in biomass is directly linked to the amount of its accessible organic compounds. Hence the COD of filtrates of different hydrothermal pretreated hay samples was measured in order to determine if there is a relation to temperature and particle size.

DOI: 10.9734/BJAST/2015/17518

Vulnerability which is a factor of concern within the context of disaster risk reduction is considered in this study. The widespread flooding which impacts massively on urban residents in the Lagos metropolis of Nigeria highlights the prevailing needs to explore the lack of social capacities of people exposed to the hazard. Social vulnerability, defined by place and social inequalities is a critical concept in this regard and its assessment underpins best practices in flood risk reduction. However, such a concept has been poorly investigated in the Lagos area most likely due to lack of knowledge about its relevance. The present study addresses this gap through critical discussions regarding social vulnerability and its assessment in relation to addressing the challenges of flooding in Lagos, Nigeria. The roles social vulnerability assessment can play in view of flood risk reduction within the context of the study area are considered along with relevant factors that influence social vulnerabilities in the area. The study concludes with some recommendations that key stake holders will find quite desirable towards flood risk reduction in the area.

Current Journal of Applied Science and Technology, Page 383-388
DOI: 10.9734/BJAST/2015/17528

In the present paper, the Iranian spacecraft is considered, and is studied from an aero thermo dynamic viewpoint to design the proper thermal protection system, for its first mission: the sub-orbital flight. The design procedure is based on the decoupling of the aerodynamic heating phenomena and the solid phase heating process. Due to the sub-orbital mission of this spacecraft as a first flight, an elastomeric material is used as an unconventional heat shield to protect the blunt body reentry vehicle. The full Navier-Stokes equations are used for heat-flux estimation during flight, and the one-dimensional equations for an ablative materials are used to design the thermal protection system, according to the structural criteria.

Current Journal of Applied Science and Technology, Page 389-399
DOI: 10.9734/BJAST/2015/16781

This study analysed the prevalent learning styles (auditory, visual and tactile) among secondary school mathematics students and how this prevalence was influenced by students’ gender and age in Benue State, Nigeria. A sample of 191 students from five randomly selected secondary schools in Makurdi Metropolis was used. Seventy eight males and one hundred and thirteen females with age ranges of 9 – 12 years, 13 – 16 years and 17 – 20 years responded to the mathematics learning style questionnaire (MLSQ). The instrument was made up of 30 statements to be responded to by students. A descriptive survey design was adopted for the study. Three research questions and three hypotheses were framed. The responses obtained was analysed using mean and standard deviation and the two-way ANOVA. The findings obtained revealed that there was no significant difference in the mean score prevalent rate of the auditory, visual and tactile learning styles among mathematics students (P = .16> P = .05), there was no significant difference in the mean score prevalent rate of the auditory, visual and tactile learning styles among male and female mathematics students (P = .09, P = .81, P = .76 respectively) and age had no significant influence on the mean score prevalence of auditory, visual and tactile learning styles among secondary school mathematics students (P  = .97, P = .71, P = .83 respectively). It was concluded that students possessed the ability to utilize and combine all three learning styles with ease, depending on the learning environment or teaching strategy or instruction of the teacher. The recommendation that was drawn suggested that, teachers should be able to accommodate and include in their lessons all three learning styles to help students comprehend the lessons better to avoid learner opposition and misunderstanding.

The study examined the perception and adaption of rice farmers to climate change in Ekiti State, Nigeria. Three Local Government Areas were purposively selected based on level of rice production in Ekiti. Well-structured and pre- tested interview schedule was used to collect relevant information from ninety respondents. Analysis was carried out using descriptive and inferential statistics. The study showed that majority of the respondents were married (85.6%) and the mean age was 50 years. Also, they were mostly males (81.1 percent) practicing farming as primary occupation (78.9%) and had secondary education (91.1%). Major source of information was from friends and family. The study established that the respondents were very much aware of the fact that climate is changing and their level of perception varies. Intensive manure application, introduction of new variety of same crop and increased weeding were the mostly adopted coping strategies with the mean of 3.9 respectively. The other identified adopted strategies by respondents in mitigating the effect of climate change to their farms include; moving to a different site, expansion of cultivated land, breeding of heat and drought resistant crop. Study concluded that rice farmers’ perception affects the adoption strategies and that farmers’ perception is affected by their socio-economic characteristics.
