ABSTRACT The paper deals with the design study of pillbox-type reduced waveguide RF window[1] for 5 GHz klystron. Numerical simulation of the window has been carried out using the software “CST MW Studio”. The proposed window is designed for 5 GHz operating frequency for handling a few kilowatts of RF power. The simulated results are […]

ABSTRACT The present study aims to evaluate the in vitro free radical scavenging behavour and antioxidant potential from the fruits of four different Indian medicinal plants (Punica granatum, Citrus limetta, Prunus armeniaca and Syzygium cumini). The free radical scavenging behavior and antioxidant potential of the aqueous extract of fruits of four different Indian medicinal plants […]

ABSTRACT Rudrasagar Lake is one of the prominent tourist destinations in north eastern part of India which surrounds Neermahal Palace. It is also declared as Ramsar site (i.e. a wetland of international importance). The surrounding Lake area was initially developed based on the fishing activity in the lake, although later on people started agricultural activity […]

ABSTRACT Marble slurry wastes are available widespread in Rajasthan as by-product of industrial process. Generally these wastes pollute and damage the environment due to sawing and polishing processes. This waste can be used for making an earthen embankment. For this, three samples of soil and two samples of marble dust from different places were collected. […]

ABSTRACT A single-phase five-level PWM inverter is presented to alleviate harmonic components of the output voltage and the load current. Operational principles with switching functions are analyzed. Two reference signals identical to each other with an offset equivalent to the amplitude of the triangular carrier signal were used to generate PWM signals for the switches. […]

ABSTRACT Explosives are an important category of environmental contaminants. 2,4,6- trinitrotoluene (TNT), the most widely used high explosive is a hazardous compound and also is a possible human carcinogen. TNT contamination is common in areas adjacent to manufacturing sites/firing/training ranges. Thus it is imperative to remediate the soil and wastewater contaminated with TNT. Phytoremediation using […]

ABSTRACT In recent years many new materials have been developed. These materials include titanium alloys, hast alloys, nimonic alloys, composites etc. These materials are used in space crafts, nuclear reactors, special cutting tools, turbine injectors etc. These new materials cannot be accurately machined by the conventional machining processes. Abrasive waterjet cutting is superior to many […]

ABSTRACT The rapid development and expansion of World Wide Web and local network systems have changed the computing world in the last decade. However, this outstanding achievement has a drawback. The highly connected computing world has also equipped the intruders and hackers with new facilities for their destructive purposes. The costs of temporary or permanent […]

ABSTRACT The asymptotic estimates of the expected number of real zeros of the polynomial  i.e.  where gj(j=1,2,…..n) is a sequence of independent normally distributed random variables is such a number. The  expected number of zeros of the above polynomial with coefficients gj(w), j=1,2,…..n in be a sequence of independent random variables defined on probability space […]

ABSTRACT The significance of isopropyl benzene has made isopropylation reactions the most widely studied using a wide range of catalysts such as Lewis acids (metal halides) i.e. aluminum chloride, and inorganic acids (Bronsted acids) i.e. sulphuric acid, hydrofluoric acid, supported phosphoric acid, and zeolite. Therefore, in order to produce higher yield of isopropyl benzene from […]
