Mechanical Properties of Polypropylene/Polycarbonate Blends

Nowadays Polypropylene (PP) I Polycarbonate (PC) blends have received interest in polymer study and tests have been done to explore its properties and behavior. This project aim to further characterize PP/PC blends compatibilized with polypropylenegraft- maleic anhydride (PP-g-MA) with varying weight composition in the area of water absorption and tensile strength. In a practical field, organic polymer materials have been shown to express some advantages such as light weight, high strength, anti-rust, and easily processable. These advantages were based on the comparison with metal and inorganic materials. However, polymer materials degrade under various circumstances for example low and high temperature, exposure to rain and sunlight, and under the water or soil. Some plastics absorb very little water at room temperature but at higher temperature it tends to absorb high amount of water and will lose properties rapidly. Eight weight ratios are considered and they are 85/10/5, 75/20/5, 65/30/5, 55/40/5, 85/15/0, 75/25/0, 65/35/0, and 55/45/0 in PP/PC/PP-g-MA respectively. The glass transitional and melting temperatures of PP, PC, and PP-g-MA were obtained by differential scanning calorimetry (DSC) and the values were consistent with literature. Meanwhile, degradation temperatures of samples were obtained by thermogravimetric analysis (TGA). Then, the polymers were compounded in twin screw extruder and fabricated by compression and injection moulding. Water absorption test were follow the ASTM Standards: D 570-98 (Reapproaved 2005) Standard Test Method for Water Absorption of Plastics and Tensile Test were follow ASTM D638 Standard Test Method for Tensile properties of rigid plastic

KEISTIMEWAAN KURMA DALAM AL-QUR’AN DITINJAU DARI PERSPEKTIF ILMU KESEHATAN

ABSTRAK Menafsirkan Al-Quran berarti berupaya untuk menjelaskan maksud dan kandungan Al-Quran, dan oleh karena objek tafsir adalah Al-Quran yang merupakan sumber utama dari ajaran Islam sekaligus sebagai petunjuk bagi manusia. Maka penafsiran terhadap ayat-ayatnya bukan hanya merupakan hal yang diperbolehkan, bahkan lebih dari itu, penafsiran Al-Quran merupakan suatu kewajiban bagi orang-orang yang memiliki kualifikasi untuk melakukannya. Seperti halnya salah satu term atau kosa kata yang dibicarakan dan tersurat di dalam Al-Quran ialah kata An-Nakhl, An-Nakhiil, An-Nakhlah dan An-Nakhlan yang berarti pohon kurma, kebun kurma dan buah kurma. Dan yang menjadi permasalahan dalam penelitian ini adalah, apakah sebab keistimewaan buah kurma ini jika di banding buah-buah lain dan bagaimana keistimewaannya buah kurma ditinjau dari perspektif ilmu kesehatan. Maka penulis melakukan penelitian dengan judul “Keistimewaan Kurma Dalam Al-Quran DiTinjau Dari Perspektif Ilmu Kesehatan.” Kata An-Nakhl, An-Nankhiil, An-Nakhlah dan An-Nakhlan dalam kitab Mu’jam Al-Mufarras Al-fadhul Quran, menyebutkan kata An-Nakhl, An- Nakhiil, An-Nakhlah dan An-Nakhlan sebanyak 20 kali dalam 16 surat. Namun, penulis membatasi penelitian ini dengan mengambil 6 ayat dari 5 surat yaitu, surat Ar-Ra'd: 4, surat Maryam: 23 & 25, surat Al-Mukminun:19, surat Yasin: 34 dan surat Ar-Rahman: 68. Maka untuk mengungkapkan masalah ini, penulis melakukan penelitian dengan menggunakan metode maudhu’i atau tematik. Karena penelitian ini termasuk dalam penelitian perpustakaan (Library Reseach), yang merujuk xv kepada literatur buku, maka penulis menggunakan kitab-kitab tafsir dan bukubuku berkaitan kurma. Sementara yang lainnya menggunakan kitab-kitab hadis, dan buku yang berkaitan dengan ilmu kesehatan. Berdasarkan penelitian yang penulis lakukan, keistimewaan kurma berbanding buah-buah yang lain amatlah banyak dan mempunyai manfa’at yang cukup tinggi terhadap kita sebagai manusia dalam aspek rohani dan jasmani. Sebagaimana Allah SWT menceritakan dalam Al-Quran Al-‘Azim peristiwa Maryam saat ingin melahirkan. Didalam pendekatan ilmu kesehatan, penulis mendapati khasiat kurma yang bergizi, berbagai vitamin dan mineral terkandung dalamnya dapat menyembuhkan berbagai penyakit karena semua bahan itu adalah penawar atau obat. Kesimpulan yang penulis peroleh antaranya yaitu : 1. Kurma adalah buah yang sangat tinggi nilai gizinya dan amat sesuai dengan tubuh badan manusia yang di ciptakan Allah SWT. 2. Manfa’at darinya bisa diperolehi semua peringkat umur dari bayi hingga orang tua. 3. Ternyata hampir semua dari kurma boleh diambil manfa’at bermula dari pangkal hingga batang. Dan dalam pendekatan ilmu kesehatan kurma berupaya: 1. Mencegah struk dan serangan jantung 2. Mempercepat penyembuhan demam berdarah 3. Mencegah pendarahan rahim 4.

An Investigation On The Synthesis And Characterization Of Flexible 3d Graphene Foam

Carbon materials, with their many different allotropes, have played important roles in our everyday lives as well as the advancement of material science and engineering. Since 2004, 2D graphene materials with their unique and interesting features have received significant attention after the discovery of 0D C60 and 1D carbon nanotube. 2D graphene is a single atomic layer of sp2 bonded carbon atoms which crystallizes in a honeycomb/hexagonal structure. It has an outstanding electrical property due to its two-dimensional shape, as well as a very high carrier mobility that is symmetrical for electrons and holes. Over the last decade, 3D structures have been produced out of graphene sheets which give rise to a new type of graphene materials called 3D graphene which had better and improved electrical conductivity, easy of functionalization, and large area. In this final year project, the synthesis of 3D graphene foam on copper foam was produced using methane (CH4) as a carbon source through chemical vapor deposition (CVD) process. The effect of some CVD parameters on the growth of 3D graphene on copper foam template such as growth temperature and growth time were manipulated. Afterwards, the sample was coated with poly(methyl methacrylate) (PMMA) to preserve the 3D graphene during transfer process. Then, the copper matrix was removed using nitric acid (HNO3). Next, the PMMA coating was removed by heating the samples in a Carbolite furnace. Afterwards, the 3D graphene samples produced were characterized by Raman spectroscopy and Thermogravimetric Analysis (TGA). Based on the ID/IG ratio, the sample produced at 1000°C, 40 minutes growth time has the fewest number of defects while the sample produced at 800°C, 40 minutes growth time has the highest number of defects. As the growth temperature increased from 800°C to 1000°C, the ID/IG ratio decreased which indicates that the graphene synthesized at 1000°C has fewer defects and better crystallinity than graphene synthesized at 800°C. Based on the ID/IG ratio approximates that all the graphene samples produced were multi-layered. Based on the I2D/IG ratio, the sample produced at 1000°C, 10 minutes is single layer graphene while the rest of the samples are few-layered graphene. The final mass percentage of 3D graphene and PMMA-coated 3D graphene sample is 18.46% and 13.84%, respectively. The remaining mass was the residue that was left behind which indicates that the 3D graphene was not completely pure and can be considered as low purity. Apart from that, a greater amount of heat energy is required to burn carbon nanotubes (CNT) compared to 3D graphene. This suggests that CNT is more heat resistant and have higher thermal stability than 3D graphene

Comparison of shariah stock screening methodology between Malaysia and International / Eirfan Syamil Ahmad Norisham

Shariah is an Islamic law derived from the divine revelation and practice of the prophet namely, al-Quran and al-Hadith. Shariah prohibits elements such as usury (riba’), gambling (maysir) and uncertainty (gharar). These elements are present in many conventional financial activities. For a Muslim, this means getting involved indirectly in prohibited practices, which is considered as a grave sin. To tackle this problem, Shariah scholars have set some acceptable boundaries for companies to do their business activities and outline steps to purify the sinful earnings. Thus, the purpose of this paper is to compare the criteria used among Islamic Indices, specifically between the FTSE Global Islamic Index (FTSE) and the Dow Jones Islamic Market Index (DJIM) in screening a permissible company for investment purposes. A comparative analysis is performed to highlight the variances of the Shariah-compliant methods and principles practiced by these renowned institutions with the latest compiled data. The two controversial criteria examined are level of debt and level of liquidity of the company. This paper will discuss the criteria, processes as well as the matters involved in the screening for Shariah-compliant and. Two sets of business screens and financial screens are profiled separately to clearly examine the similarities and differences between the different methodologies. Some of these practitioners are more specific in their listing of Shariah-impermissible activities, while some are more general in allowing more businesses to be included as permissible. The majority of these users practice a two-tier method of screening which is qualitative and quantitative. Under the quantitative screen, the range of allowable threshold ratios on non-permissible criteria differs slightly between them

Integriti dalam kalangan pekerja awam: kajian kes Agensi Keselamatan Sempadan (AKSEM) Chuping, Perlis

The main aim of this study is to examine integrity among civil servants in Malaysia. In order to achieve this, the research has selected a case study of the Border Security Agency (AKSEM) in Chuping, Perlis by focusing on the level of knowledge and integrity practices as well as on the factors that affect the deterioration of the integrity among civil servants in this agency. This study also analysed relations between demographic information such as gender, age, race, education status, service period (only for AKSEM civil servants only) and level of integrity. The study involved 30 respondents comprising 20 civil servants from AKSEM Chuping, Perlis. All the respondents had been interviewed to examine the level of knowledge and integrity practices as well as on the factors that affect the deterioration of the integrity among civil servants in this agency. The results show that the level of knowledge regarding integrity can affect the level of their integrity practices. Besides that, this study also highlights the factors that affect the decline of integrity among civil servants and provide some effective proposals in addressing the issues. All parties should play their roles in ensuring successfulness of programmes initiated by the government in enhancing level of integrity comprehensively. However, for a more comprehensive outcome, thorough analysis and adequate timeframes need to be implemented to address the problematic factors that cause higher probability of diminishing integrity among Malaysians, especially among those civil servants who serve as mediators between people and the government. If these civil servants have not possessed good integrity values, this will have negative impact on the image of government administration
