Acoustic emission (AE) is now a well established technique for damage detection, quantification and location in large structures. It appears in its principle as a technique providing real time information about the origins and the importance of the degradation mechanisms inside the material. This paper demonstrates the use of AE technique to monito

Renewable energy from the wind turbine has been focused for the alternative source of power generation due to the following advances of the of the wind turbine. Firstly, the wind turbine is highly efficient and eco-friendly. Secondly, the turbine has the ability to response for the changeable power generation based on the wind velocity and structur

We have used cellular automata integrated with GIS and remote sensing to analyze urban sprawl aiming at analyzing expansion of potential unauthorized land uses for residential, commercial and industrial based on spatial factor deriving from remote sensing high resolution data. The spatial factors considered are used as parameter to measure either l

This paper describes the unique structure of an aircraft model with and without winglet tested at Aerodynamics Laboratory, Faculty of Engineering (University Putra Malaysia) using subsonic wind tunnel of 1000 mm × 1000 mm rectangular test section and 2500 mm long. Focusing on predicting the aerodynamic characteristics of the aircraft model, three

S,S′-(Naphthalen-2-ylmethyl sulfanyl (1-p-tolyl-ethylidene) hydrazine (SNM4MA) was prepared by the condensation of S-napthalen-2-ylmethyldithiocarbazate (SNMDTC) and 4-methylacetophenone. Yellow needles of SNM4MA were obtained upon slow evaporation of a 50:50 mixture of acetonitrile and DMSO over a period of weeks. The compound crystallizes in th

The main challenges for biodiesel production are the cost of raw material (fats and oils) and the cost of processing. In oil palm industry there are large amounts of low grade oils that could be converted to biodiesel such as sludge palm oil (SPO). SPO is an attractive feedstock and a significant raw material for biodiesel production. The use of SP

Biodiesel is receiving an increased attention because of increases in crude oil prices, limited resources of fossil oil and environmental concerns. There has been renewed focus on using vegetable oils and animal fats to make biodiesel fuels. The main challenges in biodiesel industry are its production cost and limited availability of fats and oils

Drymoglossum piloselloides, Abrus precatoris, Piper bettle and Cinnamon aldehyde have been traditionally used in dentistry. However, there are not many scientific research on investigating those leafs and their therapeutic efficacy to bacteria causing periodontitis. Aims: to investigate antibacterial of extracted of Drymoglossum piloselloides, Abru

Background: The rapid social, cultural and economic changes in Bangladesh have given rise to a number of deaths that can be attributed to non-communicable diseases. The hospital records showed that death from cardiovascular diseases accounted for more than 12 percent of all deaths. Objectives: This study was undertaken to generate information that

Hypertension and obesity are established and independent risk factors for cardiovascular diseases. There are important inter-relationships between these two factors that may explain the aetiology of cardiovascular diseases. To determine the prevalence of hypertension and obesity in a rural community setting in Malaysia, and to identify their associ
