Performance Evaluation of PV Panel Under Dusty Condition

The performance of PV panel depends on the incoming sunlight on its surface. The accumulated airborne dust particles on panel surface creates a barrier in the path of sunlight and panel surface, which significantly reduces the amount of solar radiation falling on the panel surface. The present study shows a significant reduction in short circuit current and power output of PV panel due to dust deposition on its surface, whereas the reduction in open circuit voltage is not much prominent. This study has been carried in the field as well as in the laboratory. The reduction in maximum power output of PV panel for both the studies ensures a linear relation with the dust deposition on its surface. In the field study, the reduction in the power output due to 12.86gm of dust deposition on the panel surface was 43.18%, whereas in the laboratory study it was 44.75% due to 11gm of dust depositionArticle History: Received July 10th 2017; Received in revised form Sept 15th 2017x; Accepted 1st Oct 2017; Available onlineHow to Cite This Article: Tripathi, A.K., Aruna, M. and Murthy, Ch.,S.N.

A rare case of occupational lung disease – Talcosis

Talcosis/ Talcpneumoconiosis is one of the rarer forms of magnesium silicate induced lung disease, It usually occurs in the fourth decade and affects people working in talc related industries like roof, shingle, pharmaceutical companies, talcum powder industries, electric ceramics, rubber industry etc. We report a case of talc pneumoconiosis/talcosis in a 51yr old male who presented with breathlessness and dry cough for the past 5 yrs and progressively worsening for the past 5 days. Who was working in a talcum powder manufacturing company for >28yrs in the packaging section. The diagnosis was possible by history, clinical examination, Chest X-ray, PFT/DLCO, HRCT chest, Bronchoscopy & Trans bronchial lung biopsy showing interstitial fibrosis

Paleolimnological Evidence of Terrestrial and Lacustrine Environmental Change in Response to European Settlement of the Red River Valley, Manitoba and North Dakota

Limnological and terrestrial changes in three floodplain lakes are correlated with settlement of the Red River valley in Manitoba and North Dakota. Distinctive pollen, diatom and thecamoebian assemblages provide proxy evidence of the ecological changes from pre- to post-settlement periods in Horseshoe Lake, Lake Louise and Salt Lake. In the pre-settlement period (Zone I), prior to ~1812, grass and Quercus pollen dominate and are indicative of a tall grass prairie-oak riparian forest ecosystem. Diatom and thecamoebian assemblages suggest oligo- to mesotrophic limnological conditions, and more brackish water than presently occurs in Horseshoe Lake. The onset of the post-settlement period (Zone II) corresponds to distinctive terrestrial and limnological changes. A sharp decline in Quercus at the base of this zone correlates with documented regional riparian deforestation, whereas the increase in the weed taxa Salsola, Brassica, Rumex and Ambrosia is associated with the introduction of European agricultural practices and cereal grasses. Diatom and thecamoebian assemblages indicate progressive floodplain lake eutrophication, as well as increased salinity in Salt Lake. Salt Lake is the most brackish lake and supports the brackish-water foraminifera Trochammina macrescens cf. polystoma. Increased erosion and run off in the watershed has caused a more than twofold increase in lake basin sedimentation between the pre-settlement and post-settlement periods.Cette étude établit une corrélation entre les changements limnologiques et terrestres dans la plaine d’inondation de trois lacs et le peuplement de la vallée de la rivière Rouge au Manitoba et dans le Dakota du Nord. Divers assemblages polliniques, de diatomées et de thécamoébiens mettent en évidence de façon indirecte des changements écologiques entre les périodes pré- et post-peuplement aux alentours des lacs Horseshoe, Louise et Salt. Dans la période antérieure au peuplement (Zone I), soit avant 1812, la domination de la signature pollinique des graminées et du chêne indique un écosystème forestier riverain composé de graminées de haute taille et de chênes. Quant aux assemblages de diatomées et de thécamoébiens, ils permettent de penser à des conditions limnologiques d’oligo à mésotrophiques et des eaux plus saumâtres à cette période qu’actuellement dans le lac Horseshoe. La période post-peuplement (Zone II) correspond à des changements terrestres et limnologiques spécifiques. Le déclin marqué du chêne à la base de cette zone correspond en effet à la déforestation des rives de cette région, telle qu’attestée dans les documents, tandis que les taxons Salsola, Brassica, Rumex et Ambrosia correspondent à l’instauration de pratiques agricoles européennes et la culture des céréales. Les assemblages de diatomées et de thécamoébiens indiquent aussi une eutrophisation progressive de la plaine inondable de même que l’augmentation de la salinité du lac Salt, ce dernier étant le plus salé des trois lacs. Il accueille des foraminifères d’eaux saumâtres du genre Trochammina macrescens cf. polystoma. L’accroissement de l’érosion et du ruissellement dans le bassin-versant a quadruplé la sédimentation entre les périodes pré- et post-peuplement

Prevalence of Campylobacter spp. in diarrhoea samples from patients in New South Wales, Australia

Campylobacteriosis is a leading cause of bacterial foodborne disease in many industrialized countries including Australia. New South Wales (NSW) is the most populous state in Australia yet the lack of any Campylobacter species surveillance programs has led to a knowledge gap in the importance of these pathogens as causes of diarrhoea. The data collected in this study demonstrated a need for such programs. In this study, 400 human clinical fecal samples were collected from two NSW locations, Western Sydney and Wagga Wagga, and tested for the presence of Campylobacter spp. Patients were clustered by location, age and gender to assess Campylobacter spp. prevalence within these groups between the two regions. The frequency of Campylobacter spp. was higher in males compared to females in the age groups 0&ndash;4 and 5&ndash;14 years; 6.4% and 1.0%, and 8.2% and none, respectively (P &lt; 0.05). A second peak was noted in elderly adults compared with those in younger age groups. Based on the findings of the quantitative PCR analysis it was estimated that the age-adjusted prevalence of Campylobacter spp. associated diarrhoea was 159 cases per 100,000 persons.
