Lichens are universally distributed organism occurring in varied climatic condition ranging from the poles to the tropics in earth. The study  of lichen remains quite frowzy throughout the world. Though the importance of lichen in an ecosystem is very high in its own way. Lichens are just like miniature sponges that take up everything that comes their path, including air pollution (Fleishner, 1994). They synthesise many useful secondary metabolites. Among the synthesised metabolites, many of them have antiviral and antibacterial activity. To keep this view in mind the present study has done to to evaluate the antibacterial activity of two different crustose lichen species collected from Kalyani University Campus,WB. Since this is the first time study of antimicrobial activity of Cryptothecia striata and Cryptothecia scripta .

Purpose The purpose of this paper is to discuss the factors that attract (pull) or discourage (push) Palestinian students from Israel (PSI) to study at a Palestinian university, the Arab American University in Jenin (AAUJ), for the first time since the establishment of Israel in 1948. Design/methodology/approach A qualitative research method using in-depth interviews with 15 PSI who study at AAUJ attempts to define the motivations behind PSI preferring AAUJ, on one hand, and constraints, on the other hand. Findings The findings of the study show factors that attract PSI to study at the AAUJ and what subjects they choose to study there, the encounter with a similar culture and nationalism in a Palestinian campus in the occupied West Bank; the most significant difficulties and impediments they face there, whether economic or political, are discussed. This paper contributes to an understanding of the new national re-encounter between two Palestinian groups in a university campus, one under Israel’s occupation and the other that has Israeli citizenship. Originality/value It is a unique phenomenon in the trends of international students’ mobility in the world.

Studies about the measurement of outdoor tobacco smoke (OTS) are limited to a few very recent studies. In many countries around the world, within public buildings, smoking is prohibited by law. However, these prohibitions often drive smokers to move to the border of the areas where smoking is forbidden, typically the entrances of buildings, in order to smoke. When many smokers stand outdoors near the entrances, a significant “wall” of smoke is generated. This condition exposes nonsmokers to smoke and contaminates the indoor environment too. Such a situation is amplified if the outdoor external area is covered. This paper presents a work carried out in a university campus, near building entrances, with the aim of studying the second-hand smoke (SHS) exposure in outdoor conditions. Measurements of particulate matter in specific environmental conditions are evaluated to estimate the OTS impacts on the students and the academic staff. The results showed that the exposure to tobacco can be very high and even comparable to values found when tests were carried out indoors, at the same distances from the smokers. A discussion about forbidding smoking near the entrances of public buildings is reported, including considerations about the environmental and public health concerns induced by SHS exposure and the smoking activity.

Butterflies are one of the most attractive insects in the world, and they have been able to attract all kinds of peoples by their various features. This present documentation records the butterfly diversity of the three districts Jhargram, Paschim Medinipur, and Purba Medinipur, which formed the former Medinipur district. A total of 139 species belong to 94 genera and six families have been recorded. Among all families, Lycaenidae and Nymphalidae are the most abundant. Among the three districts, most species were found from Jhargram district. Fluffy Tit, Angled Pierrot and Common Lascar are the first time recorded from southern West Bengal. Rapid urbanization, deforestation, uncontrolled developmental works, and changing the character of Coastal zone is some of the threats to butterflies in these areas. So it was a great need to prepare a list of butterflies by which the past changes in the species diversity and number of butterflies in the future able to understand.

Abstract Apiosordaria is a genus of fungus with species commonly reported inhabiting soil or herbivore feces. However, studies related to the association of representatives of this genus to plants, especially in semi-arid ecosystems, are still non-existent. In this work we documented a new occurrence for Brazil of a species of Apiosordaria, associated with the palm Syagrus coronata. The collections were carried out at the Raso da Catarina Ecological Station and the analyzes were carried out at the Laboratory of Sciences of the Bahia State University, Campus VIII, Paulo Afonso. From the topographic analysis of the plant substrate in stereomicroscope and the evaluation of fungal structures under optical light microscope, the species was identified as Apiosordaria nigeriensis. This fungus was reported for the first time in Enugu, Nigeria, after being isolated from soil samples. In this work, we report the second occurrence of A. nigeriensis to the world, being the first to Brazil, representing the first record for the Americas, and highlighting the palm S. coronata as the first botanical host colonized by the species. These data broaden the knowledge about the geographic distribution of the genus, especially on the microdiversity for the caatinga biome.

INTRODUCTION: India being the second highly populated nation in the world. HIV/AIDS has acquired pandemic proportion in the world. Estimate by WHO for current infection rate in Asia. India has the third largest HIV epidemic in the world. HIV prevalence in the age group 15-49 yrs was an estimate of 0.2%. India has been classified as an intermediate in the Hepatitis B Virus (HBV) endemic (HBsAg carriage 2-7%) zone with the second largest global pool of chronic HBV infections. Safety assessment of the blood supply, the quality of screening measures and the risk of transfusion transmitted infectious diseases (TTIs) in any country can be estimated by scrutinizing the files of blood donors. After the introduction of the blood banks and improved storage facilities, it became more extensively used. Blood is one of the major sources of TTIs like hepatitis B, hepatitis C, HIV, syphilis, and many other blood borne diseases. Disclosure of these threats brought a dramatic change in attitude of physicians and patients about blood transfusion. The objective of this study is to determine the seroprevalence of transfusion transmitted infections amidst voluntary blood donors at a rural tertiary healthcare teaching hospital in Chhattisgarh. MATERIAL AND METHODS: This retrospective study was carried out in Chandulal Chandrakar Memorial Medical College, Kachandur, Durg. Blood donors were volunteers, or and commercial donors who donated the blood and paid by patients, their families, or friends to replace blood used or expected to be used for patients from the blood bank of the hospital. After proper donation of blood routine screening of blood was carried out according to standard protocol. Laboratory diagnosis of HIV 1 and HIV 2 was carried out by ELISA test. Hepatitis B surface antigen was screened by using ELISA. RESULTS: A total of 1915 consecutive blood donors’ sera were screened at Chandulal Chandrakar Memorial Medical College, blood bank during study period. Of these 1914 were male and 1 female. The mean age of patients was found to be 29.34 years with standard deviation (SD) of 11.65 Years. Among all blood donors in present study, 759(39.63%) were first time donors and 1156(60.37%) were repeated donors. 1 patient was HIV positive in first donation group while 3 (75%) were positive in repeat donation group. 7 (38.9%) were HBsAg positive in in first donation group while 11(61.1%) were positive in repeat donation group. Two patients in first donation group had dual infection of HIV and HBsAg. CONCLUSION: Seropositivity was high in repeated donors as compared to first time donors. The incidence of HIV is observed to be 0.2% and that of HBsAg is 0.94%. Strict selection of blood donors should be done to avoid transfusion-transmissible infections during the window period.

The author of the article discloses the prospects of development of the world feed production for aquaculture based on the analysis of key innovative technological and market trends. The author specifies that shortage, high cost, low ecological compatibility of traditional raw materials - fish flour - are among major limiting factors in the development of production of feeds for aquaculture. This fact, in turn, limits sustainable development of aquaculture both in Russia, and in the world in general. The article presents the overview of a current status of the world industry of feed production in aquaculture, where the regional situation is studied, as well. For the first time, there is given the outlook of innovative technologies in feed production based on the alternative sources of protein (on the example of projects of leading aquabiotechnological companies) which will determine industry’s objectives for the mid-term perspective.

Salman Rushdie remains a major Indian writer in English. His birth coincides with the birth of a new modern nation on August 15, 1947. He has been justly labelled by the critics as a post-colonial writer who knows his trade well. His second novel Midnight’s Children was published in 1981 and it raised a storm in the hitherto middle class world of fiction writing both in English and in vernaculars. Rushdie for the first time burst into the world of fiction with subversive themes like impurity, illegitimacy, plurality and hybridity. He understands that a civilization called India may be profitably understood as a dream, a collage of many colours, a blending of cultures and nationalities, a pluralistic society and in no way unitary.
