Power dissipation and time of breakdown in AC discharge of argon at a low pressure in the frequency range 5-10 kHz
...Show More Authors

The influence of 5-10 kHz audio frequency on the power dissipation in ac discharge of argon gas was studied experimentally, at pressures 50-80 mTorr and electrodes separation 10 cm (pd range 0.5-0.8 Torr.
cm). The measurements have shown that the discharge behavior in the ac circuit is equivalent to a series RC circuit. It is observed that the variation curve of discharge power P with the frequency f is approximately has a Gaussian shape. It is also observed that the curve of Pm- pd is the inverse of Paschen curve, where Pm is the maximum power in the frequency range. The time of breakdown is estimated from the curve of P- f.

BACKGROUND:

The compliance is considered one of the most important parameters which is defined as the change in volume with given change in pressure (dv/dp). It is varying inversely with both diastolic filling and modulus of chamber stiffness.

AIMS:

This study aimed to deduce the net atrioventricular compliance which is affected the trans mitral blood flow.

MATERIALS AND METHODS:

This study focuses on study group of 25 patients (15 males

Strategic Maneuvering in Commercial Advertisement: A Pragmatic Study
...Show More Authors

This study deals with strategic maneuvering in advertisement from a pragmatic point of view found in some commercial advertisements in order to investigate and analyze the pragmatic devices that are used in the strategic maneuvering and stages. The study attempts to shed light on the most fuzzy areas in advertisements that is probably how the language of advertisements employed by advertisers to affect consumers positively. The primary goal of strategic maneuvering is to discover how the pragmatic devices have persuasive techniques that are used to gain a competitive advantage and more sales. This study is a contribution to the field of research in the language used in advertising. In this research, the effectiveness of strategic man

Genetic Algorithms in Construction Project Management: A Review
...Show More Authors

Genetic algorithms (GA) are a helpful instrument for planning and controlling the activities of a project. It is based on the technique of survival of the fittest and natural selection. GA has been used in different sectors of construction and building however that is rarely documented. This research aimed to examine the utilisation of genetic algorithms in construction project management. For this purpose, the research focused on the benefits and challenges of genetic algorithms, and the extent to which genetic algorithms is utilised in construction project management. Results showed that GA provides an ability of generating near optimal solutions which can be adopted to reduce complexity in project management and resolve difficult problem
