Epidemic Curve

Health workers reported an increased number of diarrhea cases at Haibatpur village on June 17, 2012. This outbreak was investigated with the followingobjectives: to confirm the existence of diarrhea outbreak, to find out the risk factors, and propose control measures. Cases were listed; spot map and epidemic curve were drawn. Attack rate was calculated by age and sex and risk factors were found out by calculating odds ratio (OR) with 95% confidence interval (CI). Rectal swabs were taken and water specimens were collected for laboratory test. Forty-one cases of patients were identified with overall attack rate (AR) was 5% (41/780). AR among men was higher 6% (25/404) than women. There was no death.V. cholerae01 Eltor Ogawa was isolated from one (1/4) stool specimen. Spot map showed cases clustered around two ponds which were contaminated with coliform organisms. The underground water was a bit saline in nature. Using pond water for preparation of fermented rice (Panta Bhat) (OR 4.73, 95% CI 1.69–13.51), washing utensil in pond water (OR 7.31, 95% CI 1.77–42.29) were associated with cholera outbreak. Health education was done to villagers. Disinfection of two ponds with bleaching powder was done. We proposed supplying of safe drinking water and repairing defective deep tube well to village.

SummaryThe authors made a field-survey of mental morbidity in all the tribal and caste groups residing in a cluster of villages in West Bengal, India, and found that, in each group, higher socio-economic classes had higher rates of mental morbidity. Different groups having a similar cultural pattern showed no significant difference in their rates of morbidity. Groups having different cultural patterns differed significantly in their rates of morbidity. In the tribal groups some neurotic disorders were absent.

Spartina alterniflorawas introduced to Beihai, Guangxi (China), for ecological engineering purposes in 1979. However, the exceptional adaptability and reproductive ability of this species have led to its extensive dispersal into other habitats, where it has had a negative impact on native species and threatens the local mangrove and mudflat ecosystems. To obtain the distribution and spread ofSpartina alterniflora, we collected HJ-1 CCD imagery from 2009 and 2011 and very high resolution (VHR) imagery from the unmanned aerial vehicle (UAV). The invasion area ofSpartina alterniflorawas 357.2 ha in 2011, which increased by 19.07% compared with the area in 2009. A field survey was conducted for verification and the total accuracy was 94.0%. The results of this paper show that VHR imagery can provide details on distribution, progress, and early detection ofSpartina alterniflorainvasion. OBIA, object based image analysis for remote sensing (RS) detection method, can enable control measures to be more effective, accurate, and less expensive than a field survey of the invasive population.

In order to comprehensively evaluate the air pollution control status of bulk terminals, the atmospheric environment control measures and effects of Qingdao port Qiangang company in Shandong Province were studied. By means of field survey, monitoring and data analysis, the present situation of atmospheric environment of the research object was analyzed quantitatively, and compared with the national standards. The research results show that the atmospheric environment and main characteristic pollutants at the boundary of the terminal operation area meet the standard requirements under the premise of using spray, cover, windbreak and other management measures during the monitoring period.

Successful Establishment

In recent years women empowerment has become a significant issue among academicians, social workers, and policy decision-makers in India. After the successful establishment of the Panchayat system as well as reservations for women in the local bodies, there has been a tremendous change in the number of women representatives in PRIs. But women empowerment is not an easy process rather, that needs a change in the mindset of the patriarchal society, social institutions, and far more determined effort on the part of the women representatives. Sometimes it becomes difficult to serve political duties for the women representatives in this present situation where there is a lack of proper knowledge, lack of education, lots of dependencies, family influence, and so on. In this light, the present study is an attempt to examine the socio-economic conditions and experiences of the elected women representatives of Gram Panchayats of Raiganj and Islampur Blocks and their participation in different sectors of grassroots politics. The whole study is based on empirical data which have been collected through field survey.

Tea Pests

<p>Twenty one species of tea pests have been recorded for the first time from the tea gardens of Manipur which include twelve species of cutting and chewing pests, seven species of sucking pests, a stem borer and a leaf miner. Among them, red spider mite, (<em>Oligonychus coffeae</em>), leaf roller, (<em>Caloptilia theivora</em>), thrips (<em>Mycterothrips setiventris</em>) and aphid, (<em>Toxoptera aurantii</em>) were categorised as important pests and the rest as minor pests based on the observations carried out for one pruning cycle during 2010 to 2013. Field studies had shown that red spider mite (RSM) infested the tea plants all through the year with peak density of 16 mites per leaf per bush in April, whereas occurrence of thrips had been recorded with maximum abundance of 6 thrips per leaf per bush during October. On the other hand, tea aphids infested the plant from March to October with maximum of 200 individuals per 5 cm length of tea shoot in September. The stem borer, <em>Zeuzera coffeae </em>was noticed during March, April and September with an average density of 9.5 borers per 40 bushes. Among the foliage folders, leaf roller was predominant over flush worm and tea tortrix. Occurrence of leaf rolls was noticed from June to November with maximum incidence of 6 larvae per bush in October, but flushworms and tortrix were abundant even in April with the mean of 3 larvae per infested tea bush. Based on the above observation, a pest calendar was prepared for the tea pests of Manipur for planning pest control measures. Besides, 16 species of natural enemies attacking the tea pests are also reported in this article.</p>

Amaranthus tricolor (Amaranthus subgen. Albersia sect. Pyxidium) is a native species of tropical Asia. It shows high inter- and intra-population phenotipic variability that is poorly known at present. During the field survey in India (West Bengal area) a large number of plants were collected and studied from the morphological point of view. The results justify the recognition of three varieties, of which one is new for the science: var. tricolor, var. tristis and var. acutus var. nov.
