Influence of wind temporal variation to the initiate of host searching behaviour of the blood sucking bug, Linshcosteus karupus Galvao et. al. (Insecta: Hemiptera: Triatominae)
Surveillance was carried out in the xerophytic climatic condition of Kalakkad forest area (8°41’ N 77°19’E) to study the arousal and foraging behaviour of the Linshcosteus karupus (Galvao et. al.) during different dusk timing in two successive years. The photoperiod, temperature and humidity recorded at the time of investigation were 12 ± 2 hrs, 22°C – 26°C and 76% – 82% respectively. Triatomine bugs are most important vector of trypanosomiasis or Chaga’s disease, a protozoan infection of man and other mammals caused by Trypanosoma cruzi (Chagas). These bugs are nocturnal and prefer to feed and mate after the sunset. Therefore our study was conducted precisely after dusk. In our study maximum number of L. karupus were noticed late after sunset i.e. between 8- 9 pm in two years, May 2013 and May 2014. The wind formation timing was a key factor in the arousal and foraging behaviour of this bug. Similarly when the wind velocity reached to the upper day’s limit i.e. ? 6 but > 3 Km/hr again maximum individuals were collected. The total of thirteen bugs was collected when the wind was at high velocity, among them eight adults and five fifth nymphal instars. Among adults greater numbers was of males which provide a very clear idea about the attraction of adults males to females and to their hosts through the olfactory sense by wind. Observation was also made about the response of these bugs to the air temperature, as the temperature declined the number of bugs seemed aroused in an increased number. At the temperature below 22°C at kalakkad hills forest, the total collected individuals of L. karupus were eleven; this number was more than twice the bugs reported at temperature above 24°C. In the delayed condition of wind formation, the bugs suddenly started to appear when wind picked speed and the number of individuals reached to maximum limit all at once. It was presuming that insects are waiting for the wind to blow and it may be the conditional respond of its feeding behaviour. In our surveillance studies all attempted were done to understand the natural arousal and behaviour of these haematophagous bugs in its natural habitat.

Mathematical Model on Noise Pollution
For many of us, the concept of pollution is limited to nature and resources. However, noise that tends to disturb the natural sythms of life makes for one solid pollutant noise takes place when there is either exercise amount of noise or an unpleasant sound that causes temporary disruption in the natural balance. Large number of vehicle on road produce heavy noise and people get it difficult to get accustomed to that the high noise leads to different health problems like hearing problems, health issues sleeping disorders etc. the present work discusses the fundamentals of acoustics and analysis of vehicular traffic noise. A large number of sets of data were recorded at different dates in a random manner in order to account for statistical temporal variations in traffic flow conditions.

Nina’s emergence as a Liberated Woman in Manju Kapur’s the Immigrant
There are number of postcolonial theorist and critics such as Frantz Fanon, Homi K. Bhabha, and Gayatri Chakravorty Spivak contributed to postcolonialism and the postcolonial intellectuals has developed a new perspective whereby the conditions of marginality, subalterneity, plurality, mimicry, hybridity are seen as sources of energy and potential change. Many women writers, thinkers and critics have formulated a school of thought that searches for such instances in literature. Feminist literary criticism primarily responds to the way woman is presented in literature. Postcolonial feminist criticism examines how women are represented in colonial and postcolonial literature and challenges assumptions which are made about women in both literature and society. Postcolonial feminists point out the ways in which women continue to be stereotyped and marginalised, ironically sometimes by postcolonial authors who might claim to be challenging a culture of oppression. The main task of the feminist literary critics seems to oppose patriarchal norms which exist in the society. The marginalizations of women, their predicament, struggle for identity, finding their own space, celebrating the female body are the chief subjects of this trend. The protagonists of all the novels of Manju Kapur are seen as women struggling against all odds. Manju Kapur has always tried to depict the picture of the sufferings of women at deeper level in her novels. In her novels, she deals with the problems of women and their struggle to establish an identity. She in particular takes up the cause of the females who are victimized on account of conservative and traditional mind-set of the Indian masses. Most of the protagonists of Kapur are women who assert their rights and raise voice against male chauvinism. Nina is one such character who rebels against the exploitation and oppression to assert her individuality.

Weibel Instability in Plasma Low Temperature
A numerical scheme for the Weibel instability of low temperature has been developed which is a modification of the Darwin model. The Darwin model neglects the ion contribution and the theoretical model used considers homogeneous plasma in the presence of a wave low amplitude laser in the dipole approximation using the formalism of kinetic theory. In this study the coupling of the magnetic field generated by self-instability with the laser-wave field is taken into account, described by the Fokker-Planck equation. This equation is solved analytically zero order and disrupted order and distribution functions electrons were explicitly calculated. The dispersion relation of modes Weibel, who holds account of the term of coupling the quasi-static magnetic field with the high frequency field the laser wave, has been established More specifically, typical physical parameters in the experiments melting by laser; it has been revealed a reduction in the spectral range of the unstable modes and a reduction of two orders of magnitude of the rate instabilities.

Oil price, exchange rate and DJIA: Effect to Malaysian stock market
The prolonged slump in crude oil prices and the exchange rate uncertainty can adversely impact global stock market. Malaysia also feel the pinch where in August 2015, its stock market index has plunged to its lowest level in more than three years since June 2012. Thus, this study is conducted to discover the relationship between crude oil prices and exchange rate to the Malaysia stock market index. Crude oil price, exchange rate and Dow Jones Industrial Average (DJIA) are chosen as independent variables while Malaysia stock market index as the dependent variable is proxy by FBMKLCI. This study used monthly time series data covering 74 observations from July 2009 to August 2015. Employing correlation matrix test, our result shows that all independent variables have significant relationship with FBMKLCI. On the other hand, regression analysis indicates that only exchange rate and DJIA is significant in determining the movement of FBMKLCI while crude oil price is not significant. The finding further indicates that changes in DJIA will positively affecting FBMKLCI while changes in exchange rate have negative influence on FBMKLCI.
