The essential oil composition of the leaves of Artemisia salsoloides, growing in Jammu & Kashmir, India, along with its antioxidant activity, is reported in present study. Gas chromatography coupled with mass spectrometry (GC-MS) revealed the presence of eight constituents, representing 99.96% of the total oil. The major constituents of the oil were 2,4-Penta diynylbenzene (49.68%), ?-trans-ocimene (17.98%), Sabinene (16.68%), 2,5-etheno(4,2,2) propeller-3,7,9-triene (5.58%). The monoterpene content in the oil was found to be 44.70 % while as other hydrocarbon content was 55.26%. The essential oil was evaluated for antioxidant activity with DPPH radical, exhibiting an interesting antioxidant profile.

The comparative study of solvolysis of tetra ethyl lead in aqueous NaOH and aqueous KOH solution was studied with the help of ultrasonic velocity, viscosity, density and other parameters determined by using a single crystal interferometer at a frequency of 2 MHz. the ultrasonic study of tetra ethyl lead conforms that there is a significant interaction between the solute- solvent molecules and ions in aqueous alkaline solutions. The main motto of this paper is that tetra ethyl lead shows more effective interaction on which alkaline solution.

This paper is concerned with the controllability of impulsive functional differential equations with infinite delay in a Banach space. Sufficient conditions for controllability are obtained by using the measures of noncompactness and Monch fixed point therem under the assumption of noncompactness of the evolution system.

Private Label brands had seen a striking expansion in recent days. Though, initially private label brands had a low-priced strategy, retailers have taken serious efforts quality improvements in recent years. The paper examines how retailers can influence the customers for private label brands by providing additional features in their product. Furthermore, the familiarity of the products may influence the purchase decision. The research method used in this study is descriptive research. Under this study a survey is conducted with the customers in and around the Coimbatore city for their preference towards private label brands. The major limitation in this study is that a few customers led some problems in the customer service area. The study was limited only to 200 customers. The time taken for the survey was between February 2012 and June 2012. The data collected is analysed with the tools like chi-square, weighted average rank and simple percentage method .The present study shows the customer preference for private label brands only in organized retail stores. Personal bias by the respondents may have script in while answering the questions.

Traditional products of Iran were created based on cultural needs and people’s beliefs and customs as well as functional needs. This study aimed to guide designers in designing new product based on cultural factors for Iranian people. In this study, the researcher wanted to experience his perception about cultural factors that influenced creating a particular traditional product in Iran and to study how these can contribute to designer practices. This study involved with qualitative method where interview has been conducted to identify specific traditional products, which have strong influence of cultural factors. Fifteen “Cultural Factors” has been identified, which can be beneficial to the designers for future product development.

The foot is among the heaviest producers of sweat in the body, as it is able to produce over 1 US pint (0.47 l) of perspiration per day. Socks help to absorb this sweat and draw it to areas where air can evaporate the perspiration. Although perspiration is odorless and 99% water, it provides a perfect medium for bacteria to grow. The bacteria cause foot odour. Foot odour is a type of body odour that affects the feet of humans and is generally considered to be an unpleasant smell. Wearing polyester or nylon socks may increase perspiration and therefore may intensify foot odor. In order to overcome this problem, a nylon sock was with increased moisture absorbency. The super absorbent solution was prepared by using various chemicals. Then the solution was examined for antibacterial activity by well diffusion method. The nylon socks were treated with this solution by dip dry method. The finished sample shows good moisture absorbency and also having antimicrobial activity when compared with the untreated sample by the testing method AATCC (147 and 30). It’s having odor control property and also there is no any irritant reaction to contact with dermatitis by the testing method of organoleptic evaluation and Contact dermatitis testing. Ultimately, it is applicable for athletic persons and also common socks wearers.

The main objective of the present paper is to obtain certain new results in the aspects of Hypergeometric function. The results presented here are presumably new.

This research will examine synthesis of single-wall carbon nanohorns (SWCNHs) by dielectrophoresis (DEP). This will involve electrokinetic synthesis method which will produce a SWCNHs sensor. In dielectrophoresis (DEP), the carbon particles will be subjected to a non-uniform electric field and thus a force will be exerted on the particles. The materials are dielectrically polarized with electrokinetic motion in non-uniform electric fields. The region of higher electric field will attract the nanoparticles due to positive DEP force. The carbon nanoparticles are then trapped in the electrode gap and thus form an electrical connection to the external measuring circuit. This method provides a fast, simple and low cost fabrication of nanomaterial-based sensors based on a bottom-up approach.

A set of vertices D in a graph G = ( V, E ) is a dominating set if every vertex of V – D is adjacent to some vertex of D. If D has the smallest possible cardinality of any dominating set of G, then D is called a minimum dominating set. A graph G is said to be Just excellent (JE), if it to each u ? V, there is a unique ? - set of G containing u. In this paper we have obtained the domatic number of the subdivision graph of a just excellent graph.
