Jaffry Zakaria, Zulakbal Abd Karim, Azali Rahmat, Sanmuga Nathan K. Jeganathan
Open Access Library Journal (OALib Journal) , 2017, DOI: 10.4236/oalib.1104011
Abstract:
This article aims to look upon the guidelines regarding the preparation of facilities and risk management of training activities for disable athlete. The facilities and appropriate training activities are one of the vital entities to prepare them towards better performance. Suitable facilities for every group will give advantages toward any service provider; thus their facilities will always be users’ choice. However, special facilities for this group are also needed to be taken into consideration to ensure equality for them. This group needs to be given attention and helps to ensure that their success in sports area can be highlighted and they may experience what was felt by other normal athletes, indirectly. But, the facilities and non-user-friendly risk management of the training practices result to the limitation of their mobility and potential in our country’s sports arena. Lack of scientific material regarding disabled athletes in risk management field also contributes to the reason why authors wish to share discussion to give precise and useful information for readers.

Makara Seri Sosial Humaniora , 2012, DOI: 10.7454/mssh.v16i2.1462
Abstract: Tempat ngèbèr, or hanging-out places where gay men in Indonesia meet, can be found in various—though relativelyhidden—public places across Indonesia. Tempat ngèbèr as one of the more prominent sites in the constellation of gayserves not only as a space to find sexual partners, but also to socialize, to be open in expressing oneself, and to gainacceptance from one’s peers. Surabaya has a number of famous, well-known tempat ngèbèr, with Pataya being one ofthe largest places. Yet changes within the last few years have diminished its popularity. Through participant observationand non-formal interviews, this research attempts to understand how Pataya became the more prominent tempat ngèbèrin Surabaya, and what kind of changes have happened that reduced its popularity. Hopefully, this research will bringabout future studies that will investigate various adaptations that can be carried out inside or outside the site itself.

Encapsulation of a Chloroform Molecule in a Peptide Nanotube  [PDF]
Fainida Rahmat, Ngamta Thamwattana
Advances in Bioscience and Biotechnology (ABB) , 2014, DOI: 10.4236/abb.2014.59088
Abstract:

We determine the encapsulation of a chloroform molecule into a D,L-Ala cyclopeptide nanotube by investigating the interaction energy between the two molecular structures. We employ the Lennard-Jones potential and a continuum approach which assumes that the atoms are evenly distributed over the molecules providing average atomic densities. Our result demonstrates that the encapsulation depends on the size of the molecule and the internal diameter of the peptide nantube. In particular, the on-axis chloroform molecule is only accepted into a peptide nanotube whose internal radius is greater than 5 ?. If located near the edge of the nanotube, then it is unlikely that the chloroform molecule will enter the nanotube. This is due to the energy valley that the molecule will need to overcome to move past the edge into the open end of the nanotube.

Evaluation of Disparities between Transportation Needs and Trip Patterns of Men and Women in Kandahar City, Afghanistan  [PDF]

Abstract: Consideration of gender equality in transportation planning is quite a new phenomenon. However, its significance is discussed widely by several researchers, particularly, in developing countries. In Kandahar city of Afghanistan, women have limited choices when it comes to using transportation services. With respect to some cultural, social, contextual, environmental, technological and physical barriers; women do not receive equal services from the current transport sectors. Using Revealed Preference and Stated Preference techniques, a survey was conducted in Kandahar city to identify the differences between trip patterns and transportation needs among men and women of the city. Our findings show distinct and clear disparities in socio-demographic characteristics of men and women of Kandahar city leading to trip disparities. Almost all of women do not own any types of personal vehicles, they are less educated and do not have jobs. Likewise, there is a considerable gap between trip characteristics and patterns of men and women. Majority of female trips are for educational purposes while male trips are more dispersed over multiple activities. Motorcycle is the most dominant and preferred mode for men, while women are mostly walking or using available public transit. Compared to men, women were recorded to have lesser trips per day over short distances. Transportation choices of women are also limited to walking, accompanying other male members of family or using public modes. However, men are generally using their private cars, motorcycles and bicycles together with all those options available for women. The results of Multinomial Logit Model showed that all selected variables such as vehicle ownership, income, travel cost and time will be significant factors for mode choice behavior of men, though for female respondents travel time and travel cost are main factors.
Differential Evolution Immunized Ant Colony Optimization Technique in Solving Economic Load Dispatch Problem  [PDF]

Engineering (ENG) , 2013, DOI: 10.4236/eng.2013.51B029
Abstract: Since the introduction of Ant Colony Optimization (ACO) technique in 1992, the algorithm starts to gain popularity due to its attractive features. However, several shortcomings such as slow convergence and stagnation motivate many researchers to stop further implementation of ACO. Therefore, in order to overcome these drawbacks, ACO is proposed to be combined with Differential Evolution (DE) and cloning process. This paper presents Differential Evolution Immunized Ant Colony Optimization (DEIANT) technique in solving economic load dispatch problem. The combination creates a new algorithm that will be termed as Differential Evolution Immunized Ant Colony Optimization (DEIANT). DEIANT was utilized to optimize economic load dispatch problem. A comparison was made between DEIANT and classical ACO to evaluate the performance of the new algorithm. In realizing the effectiveness of the proposed technique, IEEE 57-Bus Reliable Test System (RTS) has been used as the test specimen. Results obtained from the study revealed that the proposed DEIANT has superior computation time.

Chemistry Central Journal , 2012, DOI: 10.1186/1752-153x-6-126
Abstract: Results of the present study revealed that various fractions of Sonchus arvensis significantly scavenged the free radicals (DPPH·, ABTS·+, ·OH, superoxide), however its methanolic fraction is more potent than other fractions. Significant correlation was found between DPPH·, ABTS·+, superoxide radical and total antioxidant activity with total flavonoids and phenolics contents. Phytochmical analysis revealed the presence kaempferol, quercetin, orientin, rutin, hyperoside, catechin and myricetin.From the present data it is concluded that various fractions of Sonchus arvensis significantly scavenged the free radical, which might be due the presence of polyphenolic constituent.Oxidation provides energy to living organisms for various metabolic processes. Normally a balance is present between amounts of free radicals produced in our body and antiradicals enzymatic and non enzymatic system to quench these and protect the body from their harmful effects [1]. Free radicals including superoxide anions, hydrogen peroxide and hydroxyl are extensively involved in oxidative damage at cellular level. Growing number of evidences suggest that reactive oxygen species (ROS) induced biochemical changes are decisive factors in various chronic human disease such as diabetes mellitus, cancer, atherosclerosis, arthritis, inflammation and neurodegeneration [2]. Human body has developed many mechanisms both enzymatic and nonenzymatic to eliminate ROS but not enough in severe oxidative stress conditions. Many studies have been carried out to investigate, that how to avoid the onset of oxidative diseases. The most studied system to fight against oxidative stress is to combat their level in body by supplying with greater amount of natural antioxidants, which can be attained by elevated use of vegetables and fruits. Natural antioxidants, particularly polyphenolics are safe and also bioactive. For that reason, in recent times, extensive studies have been conducted to identify plants with antiradi

Asian Journal of Information Technology , 2012,
Abstract: Foreign bodies inhalation or impaction into the airway are more commonly seen in children as compared to adults. We present the different scenarios of these cases and the photograph taken during the procedure attempted. Our intention is to illustrate how photo-documentation can be made feasible during this acute intervention. Although airway management is far more important, with the cooperation between the anaesthetist and the operating surgeon, this can be made possible. In the case studies illustrated, we have successfully captured the images of the implicated foreign bodies. It was also found that the images taken by using rigid scope has a superior quality as compared to the flexible scopes. The taken photograph is an absolute proof of the impacted foreign bodies and it can be an ideal example for teaching, examination and other education purpose.

Makara Seri Teknologi , 2002,
Abstract: Galvanized steel sheet of 0.8 mm in thickness was drilled with circle holes of 2.5 mm diameter and spacing arranged in tetragonal and hexagonal pattern. The manufacturing properties of specimen were studied through drawing and stretching simulative test. It was concluded from the results that, at high ratio of punch to hole diameter (40/2.5), the drawing properties (LDR) of both square and hexagonal perforated sheet were slightly lower than that of solid sheet, while hexagonal perforated showing LDR somewhat higher than the square one. The stretching properties (LDH) of sheet, however, were much lower than that of solid sheet while the hexagonal perforated exhibiting LDH lower than the square one. Provided the effi ciency factor was well defi ned, which was not effective in the present experiment, the intrinsic drawing properties might be indirectly determined through the simulative test by assuming the perforated materials as an equivalent continuum.
