In this study, three different concentration of organic loading rate (OLR) were investigated to examine the effect of the change in the organic loading rate on the efficiency of the biogas production. Daily amount of biogas of different type of organic loading rate (OLR), rates of production of biogas, removal efficiencies of chemical oxygen demand

Feedstock is one of the most challenging parts of building and operating an anaerobic digestion system. Feedstock quantity and quality must be established and longterm contracts. It must be secured early in the project. This is because anaerobic digestion systems must be designed around available feedstock, and not the other way around. There are t

تهدف هذه الدراسة إلى إبراز أصول وعناصر الأغلوطة والمغالطة وأصحابها في القرآن، ومقارنتها بما عُرفت به عند المناطقة. أبرزت هذه الدراسة أن أصحاب المغالطة في القرآن أصناف متنوعة، منهم من كانوا من

The implementation of the earth-air pipe heat exchanger (EAPHE) system as a passive cooling technology for both residential and commercial buildings in the hot humid climate of Malaysia is relatively new. To date this technology has not been implemented in Malaysia, although it is proven in many studies particularly in drier climates, that it has t

Motor imagery (MI) related Electroencephalogram (EEG) signal classification is one of the main challenge in designing a brain computer interface (BCI) system. Single Layer Perceptron Learning (SLPL) algorithm has a very low computational requirement which makes it suitable for online BCI system. This paper proposes an advanced and simple classifica

This paper addresses on the issue of the loss of culture and the importance of reclaiming the cultural landscape of the Minangkabau in Negeri Sembilan. Reclaiming the loss of culture is an important initiative in order to protect cultural landscape values or cultural in general. Hence, a study is conducted to provide an understanding towards the im

This paper describes the methodology used in the investigation of thermal comfort studies with the notion that energy efficient design adapted to double-storey terraced houses in Malaysia can increase thermal comfort and decrease energy consumption. The study requires a method of exploring the thermal performance of existing and hypothetical dwelli

Introduction: AKI is common and carries a high mortality rate. Most epidemiological studies were retrospective and were done in Western populations. A prospective study in a non-European population utilising the recent AKI consensus guideline is warranted. We aim to assess the AKI epidemiology in our local ICU. This will be the basis of future mult

This research project presents the effects of thermal neutron radiation of fluences ranging from 3 to 9×1013 neutron/cm2 on the electrical behaviour of quantum dot-in-a-well semiconductor samples. The samples are characterized via forward-bias and reverse-bias current densities measurement, capacitance-voltage measurement and temperature dependenc

The expansion of urbanization has received much attention since the late 19th century. A physical aspect that needs to be understood is the urban climate problem such as the urban heat island phenomenon and its factors and effects towards environment. The steady economic growth and rapid urbanization has created more concrete landscapes that can in
