Thermal transfer simulation regarding the rotational moulding of polyamide 11

Simulation of thermal phenomena in rotational moulding is very important to follow the evolution of the temperature in various zones of this process. It was a question of modelling heat gradients developing in rota-tional moulding part. Thermal model tested take into account the temperature change (thermal transfer mecha-nism) of melting and crystallization pseudo-stages (enthalpy method). Series of tests in polyamide 11 (PA11) were carried out by means of rotational moulding STP LAB, and non-isothermal crystallization kinetics of rota-tional moulding PA11 grade are measured and analysed by DSC technique type TAQ20. A result of non-isothermal crystallization of the studied polyamide was confronted with Ozawa model. In order to test the validity degree of enthalpy method (layer to layer), another approach based on Ozawa model has also been used in the case of cooling pseudo-stage. As results, the rotational moulding of PA11 was successfully carried out. The simulation of the fusion and crystallization stages, by application of Ozawa model coupled with enthalpy method gave a good representation of experimental data

Axial crushing of fiber filled thin tubes

The energy absorption capacity of a series of axially crushed tubes filled with oil palm fiber is compared with empty tube. This is to determine the viability of considering the use of such composites or bimaterials in transportation system especially in automotive application. The cross-sectional of tubes are square and rectangular in shape. The tubes arefilled with Empty Fruit Bunch (EFB)fibers and with Oil Palm Frond (OPF) fibers; and some of them were added with water or urea formaldehyde. The fibers densities are ranging from 150 kgm-3 to 300 kgm-3 . It was also found that the rectangular mild steel tubes filled with 300 kgm-3 Oil Palm Frond fiber was good in absorbing energy compared with others densities

Investigating risk reporting practices in Egypt

Traditional financial statements fail to satisfy users' needs for information because they provide only a partial view regarding a company's risk profile. Recently, risk reporting has become the focus of interest. This, however, has not been translated into empirical research that investigates risk reporting in corporate annual reports. This study addresses this gap through examining risk reporting practices in Egypt. The key objectives are to measure the extent of mandatory and voluntary risk reporting, identify the nature of voluntary risk reporting and investigate firm characteristics, corporate governance and ownership structure that could explain variation in risk reporting practices in the annual reports of Egyptian companies. In addition, the study aims to identify factors that may obstruct the presentation of risk reporting in annual reports of Egyptian companies. In the first phase, the annual reports of 106 listed companies for the years 2006/2007 were examined to measure the extent of risk reporting and examine potential determinants of risk reporting. In the second phase, 15 semi-structured interviews were carried out with academics, external auditors, regulators and financial managers to identify factors that may obstruct risk reporting in corporate annual reports. Results indicate a low level of compliance with mandatory risk reporting requirements. Also, results indicate a low extent of voluntary risk reporting with a tendency to report more past and qualitative than future and quantitative risk-related information. It is suggested that competition, role duality, board size, ownership concentration, profitability and auditor type influence the risk reporting practices of Egyptian companies. The study identified accounting practice problems (such as lack of effective profession and enforcement mechanisms), accounting education problems (such as inadequate local accounting textbooks) and the Egyptian culture of secrecy, as key obstacles to the presentation of risk reporting in corporate annual reports.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

Bachelor of landscape architecture thesis : proposed astronomical outdoor gallery at National Planetarium, Kuala Lumpur

The project presents a design and planning of the outdoor space of the National Planetarium in Kuala Lumpur. The planetarium exhibits equipment and artefacts on astronomy and space technology to travel beyond the Earth’s atmosphere. This indoor gallery allows people to observe the celestial objects and learn about phenomena in space. But the indoor spaces in the building limit the activities to educate people. Therefore, this proposal intends to extend the learning process of astronomy to the outdoor as a gallery. The 23-acre gallery is located on a hilltop of hill that affords scenic view to the city. The concept of the design is “evolution of astronomical time-line†which highlights a journey from ancient period to modern technological era. The site is divided into eight zones: Ancient Period, Mesopotamian, Egyptian, Early Greek, Chinese, Islamic, Renaissance and Modern Era which is famous for their exploration of celestial objects. Firstly, the ancient park let visitors to experience the early astronomical era from 3100B.C. such as the Stonehenge and Babylonian astronomy. Facilities such as information centre, food corner, surau, phone booth and toilet are provided. The rest of the zones are composed instruments and sculptures such as astrolabe, globe, quadrant, sundial and equatorium to highlight the character of the era and automatically become a landmark to generate emotional attachment among users. Finally, the journey of the time-line ends at Modern Era Park where visitors can interact with the exhibition items in observatory gallery, playing with the water element and small kiosk and observe the celestial objects. Children also can learn about astronomy while they are playing with the sun tunnels and other equipments in children planet. The users can experience about the evolution of astronomy after they complete their journey in all zones

Presenting the Archaeological Evidence in Aceh: International Trade Perspective

Aceh province, Indonesia. It shows that the ceramics fragment proves the connection of trade between Aceh and Southeast Asia. These specific ceramics originally come from mainland China, Thai and Vietnam. The current founding of ceramics in Malaysian Peninsula including Kedah, Melaka, and Johor confirm the similarities. It reaffirms that Aceh was the hub of international trade. This study used exploratory research approach. This approach with the narrative perspective to examine what ceramics tells us around 13th until 15th CE regarding to international trading in Lamreh, Aceh. The research will give the new perspective on historical record based on archaeological evidences. Previous researches are mainly focussing on record from international explorers. This study will help us to understand possibility to connect Aceh as part of ASEAN community to build a new international trade hub in Aceh

Smoking cessation and its relationship with religiosity: a review of literature

This study aims to systematically review the literature regarding the relationship between religiosity/spirituality and smoking behaviour. Systematic searches were conducted to identify the literature published since 2013-2019 based on sets of inclusion and exclusion criteria. Four electronic databases were used to identify the literature, including Scopus, Science Direct, ProQuest and PubMed. The search was limited to full-text articles/ review papers and in English or Malay language only. Articles on smoking prevention and other nicotine delivering devices such as vape or electronic cigarette were excluded from the study. Initially, 26,938 articles were retrieved, but only 12 were finalised to be critically appraised. Out of the 12 studies, five studies revealed a significant relationship between religious/spiritual activities and cessation while the others showed an inverse association between religiosity and smoking. Religiosity/spirituality played an essential role in influencing smoking behaviour, making it an important vehicle to complement other existing tobacco control efforts. Limited studies were focusing on the Islamic religion despite the growing number of the Muslim population worldwide. Thus further research on the integration of Islamic religion in the smoking cessation program is highly recommended, especially in a Muslim country like Malaysia
