Conservation of soil and water resources for combating food crisis in Nigeria
This article presents the conservation of soil and water resources and its effective utilization as key to sustainable agricultural development in Nigeria. This requires policies and methods that emphasize the conservation of these natural resources base. Poverty, intensification and extensification of marginal lands were identified as major threats to the sustainability of soil and water resources. The study recommends...

Overview of drug evaluation system in China
Developing a drug requires great amount of research work in chemistry, manufacturing, controls (CMC), preclinical science and clinical trials. Drug reviewers in regulatory agencies around the world bear the responsibility of evaluating whether the research data support the safety, effectiveness and quality control of a new drug product to serve the public health. This article provides an overview of the drug evaluation...

An alternative evaluation method for Likert type attitude scales: Rough set data analysis
Likert scales are the most prevalent attitude scale. However, the fact that different items could be added up to produce same attitude values decreases the validity of the Likert scale results. Rough set data analysis could perhaps be conducted to overcome related limitations. Thus, this study seeks to investigate the employability of the rough set approach for the interpretation of Likert type attitude scales. Data was...

Non-perturbative solutions of a nonlinear heat conduction model of the human head
Temperature profiles within the human head are highly influenced by the geometry and the rate of metabolic heat production. In this paper, we provide a very accurate, non-perturbative, semi-analytical solution to a nonlinear singular boundary value problem modelling the distribution of heat sources in the human head and their dependence on environmental temperature. Our analysis is based on Adomian decomposition...

Finite element analysis of the beam strengthened with prefabricated reinforced concrete plate
Various strengthening methods were frequently carried out in the world to strengthen weaker cross section beams. In this study, one beam strengthened by bonding with a prefabricated plate which has 80 mm thickness underneath and one control beam were produced. The specimens were tested in the laboratory and a single load was applied on the middle of the beam. The results of the experiments were compared with the...

Strength properties of L-profiled furniture joints constructed with laminated wooden panels
This study analyzed the effects of L-profiled corner joint design on maximum load-carrying capacity of case furniture. For massive panels material (red pine), two test groups were formed using polyvinyl acetate (PVAc), Desmodur-VTKA (polymarine) and Purocal (polyurethane-based) adhesive types. First group test samples were prepared using L-profiled corner joint and second group test samples were prepared without using...

The place of geographic information systems (GIS) in the new geography curriculum of Turkey and relevant textbooks: Is GIS contributing to geography education in secondary schools?
The national geography curriculum of Turkey has undergone radical changes and new secondary school programs were introduced by The Turkish Ministry of National Education (MEB) in 2005. The new geography curriculum recommends greater incorporation of technology in geography classes, in particular, emphasizing the deep integration of the geographic information systems (GIS) into courses. In spite of having some...

Examining the effects of mercerization process applied under different conditions to dimensional stability
In this study, mercerization processes were performed on cotton fabrics with three different weaving patterns in chain mercerizer at 60°C by applying three different time periods and three different processes under factory conditions. The fabrics, which were weaved from 20/1 open-end and 100% cotton yarns, were used in the tests. The fabrics used in the tests were applied singeing, desizing, bleaching and...

Calculation of time-varying mean velocity by different methods and determination of turbulence intensities
The raw velocity data for both stream-wise and transversal directions in unsteady flows, which are formed by generating input hydrograph, are obtained by using a flow tracker. The same hydrograph is generated 15 times and the mean values are found by calculating the average of all hydrographs. The time varying mean is obtained by using FFT, moving average, wavelet and EMD methods. The best time varying mean is selected...

Experimental investigation of sediment transport in steady flows
An elaborate experimental system is designed and built in the Hydraulics Laboratory, Civil Engineering Department, Dokuz Eylül University. The sediment transport in steady flow conditions has been studied to correlate the flow parameters with the transported sediment amount. In this paper, the experimental system, its elements and their functions are explained. The critical point for...

Designing a smart multi-agent system based on fuzzy logic to improve the gas consumption pattern
A wireless sensor network (WSN) is composed of many sensor nodes that are distributed in the environment to gather information. One of the most common application of this technology is the monitoring of environments where there are constraints regarding the setting up of wired networks. In this paper, the design of a control system based on fuzzy logic to monitor and control gas consumption with the help of smart...

An analytical study on one of the dramatic rituals of Komeijan inhabitants in Iran under the light of anthropological hypotheses and Aristotelian dramatic pattern
This paper is an analysis of whooping-cough, one of Iranian pre-Islamic rituals that functions as a way of defending people against evil. The data collection derived from the three year anthropologic study of the researcher on drama done within 67 Villages of Komeijan region in Markazi province, Iran. The methods and materials in this case were classic literature, Aristotelian dramatic pattern and...
