In this paper we obtain existence results for the positive solution of a singular elliptic boundary value problem. To prove the main results we use comparison arguments and the method of sub-super solutions combined with a procedure which truncates the singularity.

The Pareto distribution is a simple model for nonnegative data with a power law probability tail. In many practical applications, there is a natural upper bound that truncates the probability tail. This paper derives estimators for the truncated Pareto distribution, investigates their properties, and illustrates a way to check for fit. We illustrate these methods with applications from finance,...

Effective interruption of the Schistosoma life cycle is essential to blocking the parasite’s transmission, and thus truly preventing human schistosomiasis over the long term. Our current mass treatment campaigns were expected to limit transmission by reducing environmental contamination with parasite eggs. However, the process of transmission has proven to be very focal and highly efficient, su...

To better understand the gastropod community dynamics of fresh water snails in Upper Victoria Nile (UVN), spatial and temporal abundance changes assemblage were assessed biannually from April 2006 to 2021 at three transects. Biannual abundances gastropoda obtained by a ponar grab examine their structure relation Bujagali Hydropower Project (BHP). The consisted nine speciesbelonging five familie...

background: fragile histidine triad protein (fhit), as a known tumor suppressor protein, has been proposed to play crucial role in inhibiting p53 degradation by mdm2. studies have confirmed fhit interaction with p53 or mdm2, although functional interacting domains of fhit with mdm2 and/or p53 are not completely defined. thus, through determining the significant structural interacting domains of...

We write the IIB Green-Schwarz action in certain general classes of curved backgrounds threaded with Ramond-Ramond fluxes. The fixing of the kappa symmetry in the light-cone gauge and the use of supergravity Bianchi identities simplify the task. We find an expression that truncates to quartic order in the spacetime spinors and relays interesting information about the vacuum structure of the wor...

Overall 10389 snails were collected from four study areas of Punjab from November 2005 to October2006. The highest prevalence (38%) was found for Indoplanorbis followed by Physa (17%), Bellamaya(10.3%), Gyraulus (10%), Lymnaea (9.2%), Oncomelania (9%) and the lowest was found for Bulinus (6.7%).Only Indoplanorbis snails were found to be positive for Schistosoma bovis cercaria. Correlation betwe...

S. haematobium was first discovered in Sierra Leone in 1909 [1,2], and S. mansoni was later discovered in 1934 in the north of the country [1]. Recovered snail samples included both Bulinus globosus and Biomphalaria pfeifferi [1]. Peak transmission of schistosomiasis takes place at the beginning of the dry season, when water levels and habitat conditions are most suitable for snail hosts [1]. A...
