Limit laws for k-coverage of paths by a Markov-Poisson-Boolean model

Let P := {X_i,i >= 1} be a stationary Poisson point process in R^d, {C_i,i >= 1} be a sequence of i.i.d. random sets in R^d, and {Y_i^t; t \geq 0, i >= 1} be i.i.d. {0,1}-valued continuous time stationary Markov chains. We define the Markov-Poisson-Boolean model C_t := {Y_i^t(X_i + C_i), i >= 1}. C_t represents the coverage process at time t. We first obtain limit laws for k-coverage of an area at an arbitrary instant. We then obtain the limit laws for the k-coverage seen by a particle as it moves along a one-dimensional path.Comment: 1 figure. 24 Pages. Accepted at Stochastic Models. Theorems 6 and 7 corrected.

Sporadic Medullary Microcarcinoma in a Young Patient - A Rare Case

Sporadic medullary microcarcinoma of thyroid is a rare disease detected usually in 0.15% of all thyroid malignancy. We report a case of sporadic medullary microcarcinoma (MMC) of thyroid in a 24 year old male presenting as solitary thyroid nodule. There was no family history of medullary carcinoma of thyroid. Although medullary carcinoma in a familial setting have been reported, sporadic MMC is rare especially in a young patient

TLC-Bioautography Guided Screening for Compounds Inhibitory to Klebsiella Pneumoniae from Justicia Wynaadensis (Nees) T. Anders

The increasing occurrence of opportunistic infections as well as infections caused by multi-drug resistant organisms has led to new efforts in the search for novel antimicrobial compounds. Justicia wynaadensis is a scandent herb found growing in the forest and estate regions of Kodagu District. The present investigation deals with the TLC-Bioautography of the methanolic extract of J. wynaadensis, followed by GC-MS analysis of active fractions. TLC-Bioautography resulted in four clearly visible active spots showing large inhibition zones. The antibacterial activity of the methanolic extract of J. wynaadensis against Klebsiella pneumoniae MTCC 3384 could be attributed to volatile components such as phytol and to the fatty acids such as myristic acid, palmitic acid, linoleic acid and stearic aci

Indoor Study on Airborne Fungi in Swine House of Bangalore, India

In rural areas of India and other tropical as well as temperate countries a large number of people are occupationally involved with different types of animal sheds. In these sheds, a wide range of fungal growth substrates like moldy livestock foods, moldy hay, bedding of animals and their excreta are present, which could provide a huge airborne fungal spore load making these places unhygienic for the animal workers. The nature and seasonal variations of fungi have been investigated in the environments within partially and completely enclosed swine house during one-year period by fortnightly sampling from January 2011 to December 2011, using an Andersen two stage viable air sampler. The air samples were collected from indoor swine houses in Hessaraghatta village, Bangalore. A total of 69.11 CFU/m3 airborne spore and 25 species representing 14 genera were recorded which included Acremonium, Alternaria sp, A. alternata, Aspergillus sp, A. flavus, A. fumigatus, A. niger, Botrytis sp, Cladosporium sp, C. cladosporioides, C. herbarum, C.lunata, Curvularia sp, Fusarium sp, F.moniliforme, F.oxysporum, Mucor sp, Nigrospora sp, Pencillium sp, P. nigricans, Phoma, Rhizopus sp, Rhizopus oryzae, Scopulariopsis sp, Trichoderma sp, and 1 unidentified genera. The aim of the present study was performed to evaluate the quality and magnitude of exposure to airborne fungi in indoor air and to compare the seasonal variation of fungal genera with regard to these environments

Avifaunal diversity in Gulbarga region, north Karnatak

The study involves of bird fauna in Gulbarga region within radius of about 100km which include, Gulbarga University campus, Gulbarga city, Chandrampalli forest areas and Surpur- Bonal reservoir. The study area (Gulbarga) lies between17 04’ -77 42’ longitude and 16 12’ -17 46’ north latitude and is placed 45meters above the mean sea level. Gulbarga has a climate that is almost typical of south Indian pennisula with semi-arid conditions. The temperature between 14ºC, – 45ºC; in winter to in summer and the average rainfall being 702mm. The forest area of the District is 275 sq. miles, occupying about 4% of the geographical area. The forests are primarily deciduous at North Eastern Zone, with reasonably dense tree growth. Chincholi taluk itself represts 50% of the forest and possess teak, rosewood trees. The objective of the study included evaluation of species composition, relative abundance and distribution   of avifauna of the chosen region. Line and point transect technique method were used for the survey purpose. A total of 115 species of birds belonging to 16 orders and 41 families were recorded. The Species consisting 85 resident, 27 winter and summer migrants were identified. Among the birds recorded in this study, 47 species were insectivorus, 11 omnivorus, 20 piscivorous, 8 carnivorus, 17 frugivorus, and 13 grainivorus
