About the Cover

It is demonstrated that there is some illusive problem in unfolding quantum field theory relevant to the early universe. That is an inadequate formulation of quantum field momentum in previous works, which is the conjugate variable of the scalar field. Most researchers in this field define quantum field momentum as under the choice , where is the scalar field. However, it is proved that this definition in quantum domain is inadequate because its dimension does not match with that of the counterpart classical representation where is the generalized Langrangian density. We suggest some recipes for fixing this problem on the basis of reconstruction of the quantum field momentum. Quantum field theory with our improved definition of quantum field momentum does not raise dimensional problem and agrees with our previous researches.

DISCOVERY OF THE MONTH

Discovery of Australia by Captain Matthew Flinders in June 9, 1803

Brindha V

Matthew Flinders (March 16, 1774 - July 19, 1814) was an English explorer, naval officer and navigator who circumnavigated (sailed entirely around) Australia and mapped much of its coastline. He and George Bass were the first Europeans to realize that Tasmania was an island; they sailed around it. He first sailed to Australia in 1795 for the British Navy aboard the ship called the "Reliance."

A representation of zarisky topology in a ring c(x)

Pravanjan Kumar Rana

The aim of this paper is to construct a Zarisky topology in a ring C(X) through a functor C, where X is a pointed topological spaces and construct a representation of Zarisky topology in a ring C(X). In this paper we show that i) Spec(C(X)) is a Zarisky topology in a ring C(X), where Spec(C(X)) denotes the set of all prime ideals of ring C(X) and construct a functor ‘Spec’ associated with Zarisky topology; and finally ii) we study the functor ‘Spec’ associated with Zarisky topology

Evaluation of five tomato (Lycopersicon esculentum, Mill) cultivars for fruit, seed yield and quality in the forest zone of Ghana

Tengan KML, Ofori AP, Issa US, Olympio NS

Five cultivars of tomato commonly grown by tomato farmers on commercial basisin the forest zone of Ghana namely: Cocoa, Akoma, Power, Petomech and Rendo were assessed for their fruit, seed yield and quality. Cocoa emerged the highest fruit yielder followed by Akoma and Power. Petomech fruits were observed to store longer, followed by Akoma and Rendo. Rendo recorded the highest seed yield.

ANALYSIS

Single nature of matter: No wave is associated with material particle

Kanay Barik

According to Arthur Beiser, shobhit Mahajani the wave associated with particles are mathematical constructs. It does not describe the space time variation of any measurable quantity like displacement or any characteristic present in a medium. Wave picture given by Schrödinger equation represent the curve of probabilities of the entities to be at various phases away from the most probable phases of different point of time.

Larvicidal and synergistic activity of Anisomeles malabarica and Phyllanthus emblica against the larvae of common malarial vector, Anopheles stephensi Liston. (Diptera : Culicidae)

Jayakumar J, Elumalai K, Dalmin G, Krishnamurthy R

In the present investigation, an attempt was made to assess the larvicidal activity of two indigenous plants, Anisomeles malabarica and Phyllanthus emblica against the larvae of economically important malarial vector, Anopheles stephensi under laboratory condition. Present experiment revealed that the methanol extract of both the plants showed significant larvicidal activity and also combined extracts (synergistic) exhibit highest larval mortality.

Liability for Groundwater contamination by Organochlorine and Organophosphorus pesticide residues in Parbhani District

Motekar Shrinivas C

Ground water samples in Parbhani district have had a designated Maximum Contaminant Limit (MCL) of pesticides in drinking water set by the U.S. Environmental Protection Agency (EPA) and WHO guideline for drinking water. Residues of several organochlorine and organophosphorus pesticide residues were monitored in the ground water from villages of Parbhani district for two years (2012-14).

Clinical, histological, hematological, biochemical, genetic and pharmacogenomic study of human polycystic kidney disease population

Judia Harriet Sumathy V

Throughout the 20th century, the chief epidemiologic impression of polycystic kidney disease (PKD) has been what an early observer described as its outstandingly hereditary character. An Autosomal dominant form of the disease which progresses to end stage renal failure is indeed the most common genetic disorders affecting about one third of people with diabetes. The other causative factors include blood sugar, high blood pressure and inherited factors.

Reconstruction of Fundamental Quantum Field Theory for Describing Scalar Field Dynamics in the Early Universe

Choi JR

The evolution of the early universe, that is usually studied from the Einstein's field equations, is a critical issue in modern cosmology. From numerous reports published in this field, we can see that inflation universe model (Guth, 1981; Guth et al. 1985; Suresh, 2004; Kim et al. 2004; Choi, 2013; Kim, 2007; Bak et al. 1998; Kolb et al. 1990) based on scalar field dynamics is a main stream of researches in cosmology.

Optimization in machining of titanium alloy using desirability analysis

Nithyanandam J, Sushil Lal Das, Palanikumar K

Titanium and its alloys are attractive materials due to their unique high strength to weight ratio, superior corrosion resistance and thermal properties. They are widely used in the aerospace, biomedical and automotive application. They posses poor thermal properties, poor machinability, etc. When machining of Titanium alloys with conventional tools the tool wear rate progresses rapidly.
