Calcium phosphate (CaP) compounds like hydroxyapatite and tricalcium phosphates are considered to be very important biomaterials. This study used RF-magnetron sputtering (RF-MS) to deposit CaP onto 316L SS. Due to the complex nature of the effect of different sputtering parameters on the quality and integrity of the coatings, there is a need to fur

This was a prospective cohort study, carried out in the Neuro Intensive Care Unit, Department of Neurosciences, Hospital Universiti Sains Malaysia, Kubang Kerian Kelantan. The study was approved by the local ethics committee and was conducted between November 2005 and September 2007 with a total of 30 patients included in the study. In our study, u

This paper presents an approach to establish models for tool life in end milling of titanium alloy Ti–6Al– 4V using uncoated carbide inserts under dry conditions. Small central composite design (CCD) was employed in developing the tool life model in relation to primary cutting parameters such as cutting speed, axial depth of cut and feed. Flank

The recent popularity of RFID tags has generated research for accompanying miniature, low-power reader circuits. This work illustrates the design of RF complementary metal- oxide-semiconductor (CMOS) process compatible spiral inductors. Several simulators such as AWR Microwave Officereg, SONNETreg, and finite element program CST were used to provid

A high linearity CMOS RF (radio frequency) power amplifier, which has the advantage of being low-cost and easily integrated on chip has become the technology of choice for RFID readers. This work demonstrates a 3.3V single voltage self-biased 2.4GHz--2.5GHz high linearity RF power amplifier for RFID applications.CMOS 2.45GHz RF Power Amplifier for

The Letter of Credit (LC) serves as an instrument of payment in international trade. Its aim is to facilitate trade between seller and buyer in different countries. To date, the Islamic banking environment promotes the use of the Islamic LC as a method of financing in international trade, particularly to Muslims and to the general public as a whole

A new architecture to realize a modular, high speed, reconfigurable, digital Rank Order Filter (ROF) is presented in this paper. A bit-level algorithm by Kar and Pradhan has been modified in this work to implement the proposed ROF. Using the proposed digital rank selection circuit it is possible to find the element of a certain rank in a given sequ

Background: The influence of intraluminal thrombus (ILT) on the proteolytic environment within the wall of an abdominal aortic aneurysm (AAA) is unknown. This is the first study to examine the correlation between ILT thickness and the levels of matrix metalloproteinases (MMPs) and their natural inhibitors (tissue inhibitors of matrix metalloprotein

System identification in vibrating environments has been a matter of concern for researchers in many disciplines of science and engineering. In this paper, a sound approach for a Twin Rotor Multi-input Multi-Output System (TRMS) parametric modeling is proposed based on dynamic spread factor particle swarm optimization. Particle swarm optimization (

The concern for and the debate on “objectivity” in the scientific study of religions led scholars to advocate two major approaches known as “History of Religion” and “Phenomenology of Religion.” Both approaches are claimed to be “descriptive” and “value-free” as they stringently enforce the principle of epochê or distanciation
