we report a young male with an initial excisional biopsy report of melanoma of the lower back, referred to our hospital for complete excision and sentinel lymph node (sln) biopsy.  four peritumoral intradermal tc-99m phytate injection was performed and slns were detected in both axillary and right inguinal regions. on the biopsy only the right axillary sln was metastatic leading to right axilla...

The chapter proposes a method for the formal description of enterprises as complex human-technical systems. In distinction from other methods this approach is aimed at the analysis of parallel planning and allocation of resources from different points of view. The method is valid for every hierarchical level of enterprise subdivision. It allows the design of decision making systems for various ...

We establish connections between the lattices of non-crossing partitions of type B introduced by V. Reiner, and the framework of the free probability theory of D. Voiculescu. Lattices of non-crossing partitions (of type A, up to now) have played an important role in the combinatorics of free probability, primarily via the noncrossing cumulants of R. Speicher. Here we introduce the concept of no...

This paper investigates the potential for automatic mapping of typical embedded applications to architectures with multimedia instruction set extensions. For this purpose a (pattern matching based) code transformation engine is used, which involves a three-step process of matching, condition checking and replacing of the source code. Experiments with DSP and the MPEG2 encoder benchmarks, show t...

Hydromorphometric analysis as a method is considered one of the most reliable and used methods in solving hydrological problems. Where it possible to know volume runoff rest elements that enter into water balance. Geographical Information System Remote Sensing technique hydro-morphometric Wadi Al-Mohammadi basin. Al-Mohammadi, located Western Desert, main valleys flow Euphrates River. It an imp...

Given a text and a pattern, the problem of pattern matching consists of determining all the positions of the text where the pattern occurs. When the text and the pattern are matrices, the matching is termed bidimensional. There are variations of this problem where we allow the matching using a somehow modified pattern. In this paper we assume that the pattern can be scaled. We propose a new par...

Basin morphometry is a means of numerically analysing or mathematically quantifying different aspects of a drainage basin. In the present study, morphometric analysis of the Baitarani basin has been carried out using earth observation data and geographical information system (GIS) techniques. The morphometric parameters considered for analyses include the linear, areal and relief aspects of the...

the length-weight relationships for three fish species from beheshtabad river, karun river drainage (western chaharmahal and bakhtiari provinces, iran) were investigated. the values of the slope parameter ( b ) in the length-weight relationship equations were determined as 2.79 for capoeta damascina , 3.10 for chondrostoma regium and 3.09 for oncorhynchus mykiss , all of which were significantl...
