Vertical distribution of polychaetes in a semi-enclosed brackishwater pond of Nethravathi estuary was studied for one year from February 2004 to January 2005. The semienclosed brackishwater pond is a shallow water body with an average depth of 1-1.5 m with an area of 12 ha having direct connection with the estuary which opens into the Arabian sea. A total of nine species of polychaetes were ide...

Let B be a Borel set in E with volume V (B) = ∞. It is shown that almost all lattices L in E contain infinitely many pairwise disjoint d-tuples, that is sets of d linearly independent points in B. A consequence of this result is the following: let S be a star body in E with V (S) = ∞. Then for almost all lattices L in E the successive minima λ1(S,L), . . . , λd(S,L) of S with respect to L are 0...

Looking at decisiveness as crucial, we discuss the existence of an order-preserving function for the nontotal crisp preference relation naturally associated to a nontotal fuzzy preference relation. We further present conditions for the existence of an upper semicontinuous order-preserving function for a fuzzy binary relation on a crisp topological space.

We consider isotropic non lower semicontinuous weighted perimeter functionals defined on partitions of domains in R. Besides identifying a condition on the structure of the domain which ensures the existence of minimizing configurations, we describe the structure of such minima, as well as their regularity.

background: relapse is a common problem in drug user’s rehabilitation program and reported in all over the country. an in-depth study on patients’ experiences can be used for exploring the relapse process among drug users. therefore, this study suggests a model for relapse process among iranian drug users. methods: in this qualitative study with grounded theory approach, 22 participants with ri...

background and objectives: understanding and meeting the religious needs of patients could lead to the satisfaction and promotion in religious care. this study aimed to explore the patients’ religious expectations of nurses. methods: researchers used a conventional approach to content analysis in this study. eighteen patients (11 men and 7 women) purposefully were selected with maximum variatio...

Recently, on-line adaptation of binary classifiers for tracking have been investigated. On-line learning allows for simple classifiers since only the current view of the object from its surrounding background needs to be discriminiated. However, on-line adaption faces one key problem: Each update of the tracker may introduce an error which, finally, can lead to tracking failure (drifting). The ...

purpose: the main goal of this investigation was diagnosis the factors of successful marriage. method: the research methodology was qualitative by employing grounded theory method. statistical population included all couples whom living in tehran and had two years living together. sampling method was purposeful and theoretical sampling. so far 12 ones who got a high score from das& pfq and desc...
