Dynamic management of UDDI registries in a wireless environment of web services
This paper presents mechanisms for managing the content of several Universal Description, Discovery, and Integration (UDDI) registries. These mechanisms are deployed in a wireless environment of Web services. By content, it is meant the announcements of Web services that providers submit to an UDDI registry. Unlike other initiatives in Web services field that consider a single UDDI registry and a wired communication infrastructure, this paper is concerned with the following aspects: several UDDI registries are deployed, there is no wired communication infrastructure between the UDDI registries, and absence of a centralized component that coordinates the UDDI registries. The solution presented integrates users and software agents into what we call messenger. Initially, software agents reside in users\u27 mobile devices and cache a description of the Web services that satisfy their users\u27 needs. Each time a user is in the vicinity of an UDDI registry, her software agent interacts with that registry so the details stored on Web services are submitted. © Springer-Verlag 2004
Implications of ecotourism development in protected areas: A study from Rema-Kalenga Wildlife Sanctuary, Bangladesh
This article is based on visitors profile study of protected area based tourist spots of Rema-Kalenga Wildlife Sanctuary (RKWS), Bangladesh to ascertain the potential of ecotourism. Study findings shows that 69% male constitute the visitors group while the maximum number of visitors was found in the age of below 30 years. Most of the visitors were literate and among them 43% visitors were student. Most (53%) of visitors preferred to get recreation in holidays as they were employed. Visitors were highly preferred to come with friends group. About 92% respondents showed positive mind to come here in future while 89% respondents view that park has tourism potential. Most of the respondents reported the presence of wildlife (48%) most notable followed by plant diversity and tribal community as recreational. From Ï2 test it is found that highly significance association present between tourism potentiality of the wildlife sanctuary and some demographic variable like income of tourists (Ï2 = 49.138, p < 0.000), visiting pattern (Ï2 = 19.344, p < 0.000), education of tourists (Ï2 = 50.226, p < 0.000), travelling distance (Km - Ï2 = 11.427, p < 0.022), duration of staying (Ï2 = 12.867, p < 0.002), frequency of visit (Ï2 = 8.456, p < 0.015), visiting time (Ï2 = 6.530, p < 0.011), problem in the study area (Ï2 = 14.962, p < 0.021), occupation of tourists (Ï2 = 8.848, p < 0.031). If the problems addressed by the visitors were solved, RKWS would be a bright place of eco-tourism in Bangladesh

Supplementing a-Linolenic acid in the in vitro maturation media improves nuclear maturation rate of oocytes and early embryonic development in the Nili Ravi buffalo
The present study was conducted to investigate the effect of omega-3 poly unsaturated fatty acid (PUFA), α-linolenic acid (ALA; 18:3 n-3) on the in vitro maturation (IVM) of buffalo oocytes and subsequent embryonic development. Buffalo cumulusoocyte complexes (COCs; n = 2282) were in vitro matured in TCM-199 (0.6% fatty acid free bovine serum albumin, 0.02 Units/ml FSH, 1 ”g/ml 17-ÎČ-estradiol, 10 ”g/ml epidermal growth factor, 50 ”g/ml
gentamicin) supplemented with 0 (control), 25, 50, 100,
150 or 300 ”m ALA under an atmosphere of 5% CO2 in air at 38.5ÂșC for 22-24 h. The matured oocytes were then fertilized in Tyrodeâs Albumin Lactate Pyruvate (TALP)
medium and cultured in synthetic oviductal fluid (SOF)
medium. Concentrations up to 100 Όm ALA improves (P †0.05) the cumulus expansion compared to control. Higher percentage of oocytes reaching MII stage was observed at 50 Όm and 100 Όm of ALA compared to control (P †0.05). Concentrations of 150 and 300 ”m ALA were detrimental both for cumulus expansion and nuclear maturation rate of buffalo oocytes. Moreover, supplementation with 100 Όm ALA improved (P †0.05) cleavage rate compared to control and treatment with 50 and 100 Όm ALA yielded significantly higher morulae compared to control. The results of present study indicate that the supplementation with 100 Όm ALA to the IVM medium improves nuclear maturation rate of buffalo oocytes and subsequent early embryonic development
Suitability Analysis of Groundwater for Eco-friendly Agricultural Growths in Food Basket of Pakistan
Water is an important component of earthâs atmosphere and it sustains ecosystems, agriculture and human settlements on earth (Samson et al., 2010). Salinity, sodicity and toxicity generally need to be considered for the evaluation of suitable quality of groundwater for irrigation (Khan et al., 2014; Cobbina et al., 2012; Todd and Mays, 2005). In Thal Doab Aquifer (TDA) groundwater occurs as a layer of fresh water over saline water and its availability is subjected to recharging potency of the Indus and Chenab rivers (Hussain et al., 2017 a, 2016 a)
Caspase deficiency alters the murine gut microbiome
Caspases are aspartate-specific cysteine proteases that have an essential role in apoptosis and inflammation, and contribute to the maintenance of homeostasis in the intestine. These facts, together with the knowledge that caspases are implicated in host-microbe crosstalk, prompted us to investigate the effect of caspase (Casp)1, -3 and -7 deficiency on the composition of the murine gut microbiota. We observed significant changes in the abundance of the Firmicutes and Bacteroidetes phyla, in particular the Lachnospiraceae, Porphyromonodaceae and Prevotellacea families, when comparing Casp-1, -7 and -3 knockout mice with wild-type mice. Our data point toward an intricate relationship between these caspases and the composition of the murine gut microflora
The α1-adrenergic receptors: diversity of signaling networks and regulation
The α1-adrenergic receptor (AR) subtypes (α1a, α1b, and α1d) mediate several physiological effects of epinephrineand norepinephrine. Despite several studies in recombinant systems and insightfrom genetically modified mice, our understanding of the physiological relevance and specificity of the α1-AR subtypes is still limited. Constitutive activity and receptor oligomerization have emerged as potential features regulating receptor function. Another recent paradigm is that ÎČarrestins and G protein-coupled receptors themselves can act as scaffolds binding a variety of proteins and this can result in growing complexity of the receptor-mediated cellular effects. The aim of this review is to summarize our current knowledge on some recently identified functional paradigms and signaling networks that might help to elucidate the functional diversity of the α1-AR subtypes in various organs

89929.pdf (publisher's version ) (Open Access)BACKGROUND: Before strategies or protocols for oral health care can be advised at population level, epidemiological information on tooth decay patterns and its effects on oral function are indispensable. The aim of this study was to investigate influences of socio-demographic variables on the prevalence of decayed, missing, filled (DMF) and sound teeth (St) and to determine the relative risk of teeth in different dental regions for D, M, and F, of adults living in urban and rural areas in Southern Vietnam. METHODS: Cross-sectional DMF and St data of 2965 dentate subjects aged 20 to 95 living in urban and rural areas in three provinces were collected by means of a self-administered questionnaire and an oral examination. The sample was stratified by age, gender, residence and province. RESULTS: The percentage of subjects having missing teeth was high for all ages while it was low for subjects with decayed and filled teeth. The mean number of missing teeth increased gradually by age from approximately 1 in each jaw at the age of 20 to 8 at the age of 80. The number of decayed teeth was relative low at all ages, being highest in molars at young ages. The mean number of filled teeth was extremely low at all ages in all dental regions. Every additional year of age gives a significantly lower chance for decay, a higher chance for missing, and a lower chance for filled teeth. Molars had a significantly higher risk for decay, missing and filled than premolars and anterior teeth. Females had significantly higher risk for decayed and filled teeth, and less chance for missing teeth than males. Urban subjects presented lower risk for decay, but approximately 4 times greater chance for having fillings than rural subjects. Low socio-economic status (SES) significantly increased the chance for missing anterior and molar teeth; subjects with high SES had more often fillings. CONCLUSIONS: The majority of adults of Southern Vietnam presented a reduced dentition. The combination of low numbers of filled teeth and relative high numbers of decayed and missing teeth indicates that the main treatment for decay is extraction. Molars are more at risk for being decayed or missing than premolars and anterior teeth
