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.

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.

This paper will explain briefly about a selected model of instructional and interaction design. The intensive review from a several literature has done and every fact against each selected model has analyzed to identify their advantages and disadvantages. Based on their advantages listed, in intend to overcome their weakness and enhance the instructional model in order to make the instructional and interaction model more relevant in this age, this paper will proposed a new interaction design model for chronological infographic development. Apps Mobile is a latest technology as a platform to disseminate information and educate people by use infographic approach. To convey the information, which is relate with time line and historical information in 21st century, digital chronological infographic is a appropriates matter to apply.

The primary concern of this study was whether there is a relationship among teachers' feedback and type of class (task-based or traditional) ,feedback in education has got various types and fields ,but tutor's feedback to students errors was the researcher's concern.How the tutor corrected the learners in these two kinds of classes can show the researchrers and tutors the effects of feedbacks on learning and teaching and also communicating.To aim this,The researcher examined the students in two groups and examining the teachers' feedback to defining four types of learners errors (M orphosyntax , Semantic, Phonological, Lexical ).Task which was taught in TB class was ordering and matching . Using various sorts of tasks in order to improve students performance in real world (Skehan 1996a).The method which used to analysis data was be Chi-square.The results of the present study revealed that there was no significant relationship between type of class and tutor's feedback .

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.

Tabernaemontana divaricata (L) R. Br. (Apocynaceae) commonly known as Tagar in Bengali. It is a garden plant in tropical countries and found throughout the Indian subcontinent. The present investigation assessed the scavenging potential by 1, 1-diphenyl-2-picryl-hydrazyl (DPPH) assay. All of the extracts exhibited potent in vitro free radical scavenging activity that increased with extract concentrations. The methanol extract was found to be the most potent in this regard, followed by the benzene and ethyl acetate extracts. Therefore, the present study confirms marked in vitro free radical scavenging activity Tabernaemontana divaricata leaves.

The curriculum is beneficial activities that provide many benefits to students. The purpose of this study was to look at the students' perception of involvement in extra-curricular activities of the students' personality enhancement that can impact the discipline and leadership style. A total of 278 students have taken as samples, representing an estimated population of 1000 student semester 1 and 2 Polytechnics Ibrahim Sultan (PIS) that are directly involved in the subject of AR 101 and AR 201 Co-curriculum Curriculum 2. Researchers use questionnaires circulated to selected respondents. The data obtained from the findings of the questionnaire were analyses by using that Statistical Package for Social Science (SPSS) version 19. The results of this analysis that will generate a percentage and mean based on data obtained from the questionnaire. The results mean the study was 0.84 for positive questions and items for item negative 0.20 question that reflects students agree that extra-curricular activities capable of improving the personality.

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.

This study has been carried out of calculating potential energy curves (Deng-Fan potential and Varshni potential) of ground state of diatomic molecule (HCl). Potential energy curves depended on spectroscopic Parameters (?e, ?exe, re, ?, µ, ?, De ,) and our results have been compared with experimental results.

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.
