Sultan Azlan Muhibbuddin Shah Ibni Almarhum Sultan Yussuf Izzuddin Shah Ghafarullahu-lah, GCB, KSTJ was the 34th Sultan of Perak and was the ninth Yang di-Pertuan Agong of Malaysia from 26 April 1989 to 25 April 1994. The child of a royal father and commoner mother, he grew up in Perak, Malaysia. During school he played field hockey, subsequently playing for the Perak team. He trained to be a lawyer in the United Kingdom. Upon returning to Malaysia, he soon became a judge and quickly rose through the legal ranks. In 1965, he became the youngest person appointed to the High Court of Malaya, and in 1982 he became the youngest ever Lord President of the Federal Court, the country's highest judicial rank.After his uncle died in 1984, Azlan Shah became the Sultan of Perak. He became the Yang di-Pertuan Agong of Malaysia in 1989, serving a five-year term before returning to his post as Sultan of Perak. In 2009, he exercised his royal authority to prevent the dissolution of the Perak parliament, sparking a constitutional crisis. Ultimately, the legal system ruled Sultan Azlan had acted properly.During his career, Sultan Azlan Shah was awarded more than 3 dozen Malaysian and foreign honours. Dozens of buildings and other projects were named after him, including a genus of insects. He was known as the "Father of Malaysian Hockey" for furthering field hockey at home and abroad, and was the patron of dozens of organisations. With his wife Tuanku Bainun Binti Mohd Ali, Sultan Azlan had five children. Wikipedia.

Porcelain balls as grinding media are produced by firing process of clay, quartz and feldspar mixtures. This application need high technological properties such as high compressive strength and hardness, wear resistance, low water absorption and excellent chemical resistance. These properties are associated with higher firing temperatures. The porcelain balls were prepared by mixing 30 wt% clay, 40 wt% feldspar and 30 wt% quartz. The samples were sintered at 1200 °C, 1230 °C, 1250 °C, 1270 °C and 1300 °C for 2 h with heating rate of 3 °C/min. Both green powder and fired samples were characterized by X-ray diffraction (XRD), X-ray fluorescence (XRF) and field emission scanning electron microscopy (FESEM).The properties of the fired samples were evaluated by compressive strength, hardness, shrinkage, water absorption, bulk density, and porosity measurement. Increasing of compressive strength, hardness and density are associated with increasing of firing temperatures. Porcelain balls PB1 and PB2 can be produced as grinding media with optimum mechanical and physical properties at firing temperature 1270 °C and 1250 °C, respectively. © 2017 Trans Tech Publications, Switzerland.

Background: Bovine brucellosis is an important disease affecting cattle characterised by abortion, still birth, reduced milk production, weak foetus and infertility in both males and females. There is wide distribution of the disease among cattle and several wildlife species. Bovine brucellosis is commonly caused by B. abortus and very occasionally B. melitensis and B. suis. The distribution of bovine brucellosis in cattle has not been described in Malaysia. In this paper we describe the distribution, pattern and trend of bovine brucellosis in Peninsular Malaysia between 2000 and 2008 based on serological data obtained from nationwide B. abortus serosurveillance activities in cattle populations.Results: Brucella antibodies were detected in 21.8% of sampled herds (95% CI, 21.01-22.59) and 2.5% (95% CI; 2.45-2.55) of sampled cattle. The state of Pahang had the highest animal and herd-level seroprevalence of 5.3 and 43.6%, respectively. The herd-level seroprevalence varied but remained high (18-26%) over the period of study and generally increased from 2000 to 2008. Seropositive herds clustered around the central part of the peninsula within the period of the study. The months of September, October and November illustrated the highest rates with corresponding seroprevalences of 33.2, 38.4 and 33.9%, respectively. A noticeable variation was observed in the cattle-level seroprevalence, but the rate remained relatively low (<5%). The chi-square statistics showed herd size (χ2 = 1206.077, df = 2, p = 0.001), breed (χ2 = 37.429, df = 1, p = 0.001), month of sampling (χ2 = 51.596, df = 11 p = 0.001), year (χ2 = 40.08, df = 8, p = 0.001) and state (χ2 = 541.038, df = 10, p = 0.001) to be associated with increased seropositivity.Conclusion: Bovine brucellosis is widespread among herds in Peninsular Malaysia at a low within-herd seroprevalence rate. © 2013 Anka et al.; licensee BioMed Central Ltd.

The aim of this research is to study the efficiency of symplectic and non-symplectic Runge-Kutta methods in solving Kepler problem. The numerical behavior of the Runge-Kutta (RK) methods that are symmetric such as the implicit midpoint rule (IMR), implicit trapezoidal rule (ITR), 2-stage and 2-stage Gauss (G2) method are compared with the non-symmetric Runge-Kutta methods such as the explicit and implicit Euler (EE and IE), explicit midpoint rule (EIMR), explicit trapezoidal rules (EITR), explicit 4-stage Runge-Kutta (RK4) method and 2-stage Radau IIA method (R2A). Kepler problem is one type of nonlinear Hamiltonian problem that describes the motion in a plane of a material point that is attracted towards the origin with a force inversely proportional to the distance squared. The exact solutions phase diagram produces a unit circle. The non-symplectic methods only reproduce a unit circle at certain time intervals while the symplectic methods do produce a unit circle at any time intervals. Some phase diagram show spiral in or spiral out patterns which means the solutions are running away from the unit circle. This also means that the absolute error will be increasing in long time integration. The numerical experiments for the Kepler problem are given for many time intervals and the results show that the most efficient method is G2 of order-4 and surprisingly RK4 seems to be efficient too although it is not a symplectic nor a symmetric method. The numerical results on Kepler problem concluded that, the higher the order of the method, the most efficient the method can be in solving Kepler problem despite whether they are explicit or implicit or symmetric and symplectic. © 2017 Author(s).

In this study, six experiments to produce precipitated calcium carbonate were carried out, two experiments without terpineol and four experiments with terpineol. The volumes of terpineol used were 1 mL and 2 mL with 90 % purity. The starting material used was calcium oxide. Terpineol and sucrose were used as additive. The flow rates of carbon dioxide gas used were 0.2 L/min and 2 L/min. Precipitation concept was employed in producing precipitated calcium carbonate (PCC). PCC products produced were analysed using X-ray fluorescence (XRF) and Field Emission Scanning Electron Microscope (FESEM). XRF was used to determine elemental oxides such as calcium oxide, iron oxide, manganese oxide, etc. FESEM was used to determine the morphology of the PCC produced. The highest purity of calcium carbonate obtained was from PCC3 that used 1 mL terpineol with CO2 gas flow rate 0.2 L/min. The highest amount of PCC product produced was 20.1 g with flow rate of CO2 gas 0.2 L/min and without terpineol. Grain shape PCC was produced with flow rate of CO2 gas 0.2 L/min and without terpineol. Cubic shape PCC was produced with flow rate of CO2 gas 0.2 L/min and with 1 mL terpineol.

The aim of the study was to investigate the influence of ZrO2 on the crystallization and properties of leucite phase from K2O -Al2O3- SiO2 glass-forming melts. A starting glass composition of weight %; 60.7-63.2% SiO2, 16.6% Al2O3, 11.6% K2O, 5.10% Na2O, 2.5-5.0% ZrO2, 0.5% TiO2 and 0.5% LiO2 was melted in an electric furnace, followed by quenched in cool water to produce glass frit. Malaysian silica sand from Terengganu was used as the SiO2 source. The glass powders were ball milled and compressed to form 13mm diameter discs using cool isostatic pressing. The discs were sintered at 650°C, 700°C, 750°C, 800°C and 850°C for 1 hour and characterised using X-ray diffraction (XRD) and field emission scanning electron microscope (FESEM). The results indicate that the amount of ZrO2 additive is one of the key factors controlling of leucite crystallization. The properties of sintered disc specimens were studied using three point bending, diametral and Vickers microhardness test. The results showed that the mechanical properties of leucite glass-ceramics increased as the amount of ZrO2 was increased. © (2014) Trans Tech Publications, Switzerland.

The motivation of this work is to improve fatigue life of the alloys steel power transmission shafts of the palm oil screw press machines in a Malaysia palm oil company. In order to improve daily productions of the palm oil, a high extraction efficiency of the machine with bigger crushing forces are required. Consequently, the failures due to torsional fatigue would become susceptible to the shafts. The shaft materials of SAAB 709 which has nearest equivalent properties to AISI4140 were then taken for sequential treatments and examinations. Carburizing processes with different combinations of soaking temperatures of 850 °C and 900 °C and soaking times of 2. h and 4. h were carried out. Standard mechanical tests were then conducted for determining the hardness and the ultimate tensile strength of the specimens. Different soaking temperature and time would result in different carburizing depths that in turn influence the fatigue endurance limit under bending torsional loadings. © 2011 Elsevier Ltd.

Summary An M/G/C/C state dependent queuing network measures the performance of a system whose service rate decreases with the increasing number of residing entities. However, the performance in terms of throughputs, levels of congestions, the expected number of entities, and the expected service time is typically analyzed based on a series of arrival rates without any further discussion on the optimal arrival rate. This paper derives the optimal arrival rates of corridors in a topological network using calculus and numerical analysis approaches. These optimal rates are then used as capacity parameters in the network's flow model to obtain the optimal arrival rates that maximize its total throughput. To ease the construction and performance evaluation of the network, we design and construct an M/G/C/C framework based on the Object-Oriented Programming approach that integrates the lingo software as an optimization tool. The framework is then tested on virtual and real networks. This framework can be used to develop a more advanced traffic management tool for studying and managing traffic flow through a complex network. Copyright © 2015 John Wiley & Sons, Ltd.

Hematite nanoparticles with average particle size of 75.6 and 93.4 nm were produced by mechanical grinding technique using planetary ball mill. The ground hematite were characterized by X-ray diffraction analysis technique, specific surface area analysis (BET), transmission microscope (TEM) and scanning electron microscope (SEM). The effects of different properties of hematite particles used as a catalyst for decolorization of synthetic dye, Remazol Red 3B (RR3B) were investigated. The experimental results show that smaller particle size of 75.6 nm decolourized at the rate of 95.8% within 10 min reaction while larger particle size of 93.4 nm decolorized at the rate of 95.9% within 60 min reaction. The decolorization of RR3B dye by both catalyst were achieved with minimum iron leached (<5 mgL-1) which fulfill the Malaysian Environmental Quality (Industrial Effluent) Regulations 2009. The continuous mode for decolorization of RR3B was carried out and complete decolorization was achieved with low iron dissolution which demonstrates the possibilities of using milled hematite as catalyst for large-scale textile industry wastewater treatment applications. © (2015) Trans Tech Publications, Switzerland.
