The Amorphous-Crystal Interface in Silicon: a Tight-Binding Simulation

The structural features of the interface between the cystalline and amorphous phases of Si solid are studied in simulations based on a combination of empirical interatomic potentials and a nonorthogonal tight-binding model. The tight-binding Hamiltonian was created and tested for the types of structures and distortions anticipated to occur at this interface. The simulations indicate the presence of a number of interesting features near the interface. The features that may lead to crystallization upon heating include chains with some defects, most prominently dimers similar to those on the Si(001) 2x1 reconstructed free surface. Within the amorphous region order is lost over very short distances. By examining six different samples with two interfaces each, we find the energy of the amorphous-crystal interface to be 0.49 +/- 0.05 J/m^2Comment: Submitted to Phys. Rev.

Factors affecting students participation in extra-curricular

Extracurricular activity is a complementary of the requirement and interest in the student academic development. Extracurricular learning styles can be implemented in the form of informal where it can provide effective learning experiences to the students. In extracurricular development, every activity has its own goals and interests that can influence the students to participate in the particular activities. Nowadays, students are more likely to engage or spending their time with unbeneficial activities or isolate themselves in the virtual world. Several studies have been conducted and found that there are factors influence or prevent the students from participating in the extracurricular activities they intended to. These factors have been categorical into three main constraints; structural constraints, intrapersonal constraints, and interpersonal constraints. These main constraints referred to many factors that can influence student participation in extracurricular activities

Pemanfaatan Teknologi Internet Dalam Pendidikan

Internet technology keeps on developing and touching various aspects of human daily life. Starting from the very simple utilization of internet, such as the use of email for communication purposes, browsing varied information, up to the relatively advanced one, such as designing and developing homepage or the use of internet for shopping purposes (e-shopping). Some initiatives, either individually or in collaboration, to utilize internet for learning has been conducted by some Secondary Schools that have equipped themselves with computers and other necessary equipment needed, both hardware and software. Socialization for introducing the utilization of computer and internet can be begun from the more equipped Secondary Schools in the cities of provincial and district levels in line with the availability of internet infrastructure connectivity

Integrating vocational training in culinary arts and Islamic studies at juvenile rehabilitation centres: Malaysian experience

The Juvenile Rehabilitation Centres (JRC) in Malaysia aims to provide shelter, counselling and skills training to juveniles specifically for those who wish to transform themselves from the regrettable misdeeds they have committed. At JRCs, an integrated Culinary Vocational Training and Islamic education forms part of their training curriculum. The skills acquired should enable trainees to secure jobs upon completion of training. However, there are some training institutions that lack systematic training structures resulting in trainees becoming less skilful in both vocational and Islamic education. The objective of this research is to identify the effectiveness of an integrated Culinary and Islamic Education curriculum implemented at JRCs in Malaysia. This is a descriptive survey and data was obtained using questionnaire and interview. Respondents comprised 92 trainees, four managers, four culinary trainers and four Islamic education teachers, all from four different JRCs. The findings show that the trainees are happy with their trainings that brought about positive effects for them. Some suggestions have been made to provide improvements in the implementation of the course among them the inclusion of prayers in the Islamic education syllabus

Politik Anggaran Dalam Pelaksanaan Pilkada Serentak Di Indonesia

This paper examines the politics of public budgeting relating to the regional head elections were held on 9th December 2015 for the first time. Election will be held for seven times from 2015 to 2027 in order to reduce election costs. However, the budget process is not easy to imagine because the technical rules are unclear. Meanwhile, elites having interests have strong influence to the budget process. The paper attempts to examine how public participation needs to be improved in the budget process, particularly regarding to the implementation of elections that will create budget democracy

Polyethersulfone/HFO mixed matrix membrane for enhanced oily wastewater rejection

The recent growth of oil and gas industry has led to the increase of oily wastewater release. Membrane technology has been in the spotlight in recent advancement to treat the oily wastewater. Fouling due to surfactant adsorption and/or oil droplets plugging the pore has become one of the major hindrances in most of the research on oily wastewater treatment. In this work, self-synthesized hydrous ferric dioxide nanoparticles (HFO NPs) via chemical precipitation method were incorporated in polyethersulfone (PES) to fabricate a novel nanocomposite mixed matrix membranes (MMMs) for ultrafiltration (UF). The morphologies and physicochemical properties of prepared HFO NPs and MMMs were characterized using Scanning Electron Microscopy (SEM) and Transmission electron microscope (TEM), contact angle goniometer, before further subjected to water permeation test and oil rejection test. It was found that contact angle of membrane decreased remarkably with an increase in HFO nanoparticle loading from 70° to 38° at which proved its improved hydrophilicity which led to a significant rise in permeate flux, achieving 168.06 L/m2h bar in comparison to 63.67 L/m2h bar shown by the plain PES membrane. Total rejection of oil (100% rejection) demonstrated by the MMMs has confirmed the superior potential of PES/HFO UF membrane for total purification of oily wastewater especially to be reused in oilfield and refinery processes as well as to be released to the environment

Mengintegrasikan Nilai-nilai Anti Korupsi Dalam Pembelajaran Pendidikan Agama Islam Di Sekolah Menengah Atas

This paper discusses the anti-corruption values which are supposed to provide a solution to the problems of crime of corruption that are befalling the nation. The research aimed to describe and integrate anticorruption values into subjects of Islamic Education in High School. This is done because the subjects of Islamic Education in High School has a strategic role in achieving the goals of national education which is then internalized into the psyche of learners. The approach used is qualitatively using literature study. From the results of this study found a draft of lesson plan, contained in them values such as honesty, caring, self-reliance, discipline, responsibilities, hard work, temperance, courage and justice

Prevalence of motile Aeromonads in chicken meat and their growth during refrigeration storage

The presence of motile aeromonads in chicken meat from the local wet markets was studied. The finding showed that 83.3% of the meat was positive for motile Aeromonas. The most frequently isolated species was Aeromonas sobria (57.0%), followed by A. hydrophila (23.0%) and A. caviae (20.0%). The Aeromonas sp. count at time of purchase which was in the range of 13 x 102 /g to 23 x 103/g, was found to increase about 10 to 100- fold after seven days of refrigeration at 5°C
