in this study 121 prescapular, prefemoral and popliteal lymph node of male healthy camel from mashhad abattoir were collected. after collecting of specimens factors such as: length, width, thickness, weight, volume and density of each lymph node were measured by caliper device. all factors were analyzed and compared using excel program. it was revealed that, normal dimensions of right prescapul...

Avoiding collisions is one of the key roles of mediaaccess (MAC) protocols. Since MACAW and 802.11, carrier sense and exchange of request-to-send (RTS) and clearto-send (CTS) packets have been used to prevent concurrent communication in wireless networks. Yet these approaches have significant cost: they prevent all concurrent communication, even exchanges that might not result in loss; they red...

introduction: several radiotracers are being used for sentinel node mapping in patients with breast cancer. in the current study, we reported our experience with 99m-tc phytate for sentinel node mapping in mashhad university of medical sciences. methods: all breast cancer patients who underwent sentinel node mapping using 99m-tc phytate were included. all patients received intradermal peri-areo...

to review children with kawasaki disease admitted in 17-shahrivar hospital of rasht from 1999 to 2007. we reviewed retrospectively 64 children with kawasaki disease between 1999-2007 admitted in 17-shahrivar hospital of rasht. frequency distributions of variants including age, sex, season, clinical and laboratory manifestations, response to treatment and complications of the patients were abstr...

In this paper the properties of node-node adjacency matrix in acyclic digraphs are considered. It is shown that topological ordering and node-node adjacency matrix are closely related. In fact, first the one to one correspondence between upper triangularity of node-node adjacency matrix and existence of directed cycles in digraphs is proved and then with this correspondence other properties of ...

background: the diagnosis of toxocariasis heavily depends on immunological tests because the number of parasites is usually few in infected tissues, unless they migrate into an organ such as eye. in general, patients with ocular toxocariasis have serum anti- t canis antibody titres that are significantly lower than those with visceral toxocariasis. objective: to diagnose the asymptomatic toxoca...

Transit-oriented development (TOD) is generally understood as an effective urban design model for encouraging the use of public transportation. Inspired by TOD, node-place (NP) was developed to investigate relationship between transport stations and land use. However, existing studies construct NP based on statistical attributes, while importance travel characteristics ignored, which arguably c...

Abstract Graph embedding is a transformation of nodes network into set vectors. A good should capture the underlying graph topology and structure, node-to-node relationship, other relevant information about graph, its subgraphs, themselves. If these objectives are achieved, an meaningful, understandable, often compressed representation network. Unfortunately, selecting best challenging task ver...

The performance of prioritized DQDB MAN under bursty traac environment is studied in this paper. The tagged node model is adopted to simplify the analysis. The processes of the packet arrivals to the tagged node, the empty-slot pattern from upstream, and the request pattern from downstream are assumed to be Markov Modulated Poisson Processes, a more general and appropriate model to capture the ...

Information security in infrastructureless wireless sensor networks (WSNs) is one of the most important research challenges. In these networks, sensor nodes are typically sprinkled liberally in the field in order to monitor, gather, disseminate, and provide the sensed data to the command node. Various studies have focused on key establishment schemes in homogeneous WSNs. However, recent researc...
