the berriasian-valanginian fahliyan formation forms one of the giant reservoirs in the subsurface of the abadan plain, onshore iran. a detailed petrographical analysis of the available cores and thin sections revealed that the different diagenetic parameters influenced the reservoir quality of the fahliyan formation in this field. the fahliyan formation has been influenced by three diagenetic e...

a novel gram-positive actinobacterium isolated from a human clinical source. Four-year prospective study of STAPH-IDENT system and conventional method for reference identification of Staphylococcus, Stomatococcus, and Micrococcus spp. Alvarez-Grande J. Relapsing bacteraemia due to Micrococcus luteus in a haemodialy-sis patient with a Perm-Cath catheter. To the Editor: Some 80% of parasitic infe...

routing in ad-hoc networks, specifically intelligent-based ones, is a highly interested research topic in recent years. most of them are simulation-based study. large percentages have not even mentioned some of the fundamental parameters. this strictly reduces their validity and reliability. on the other hand, there is not a comprehensive framework to classify routing algorithms in wireless sen...

Vehicular ad hoc networks are an emerging technology with an extensive capability in various applications including vehicles safety, traffic management and intelligent transportation systems. Considering the high mobility of vehicles and their inhomogeneous distributions, designing an efficient routing protocol seems necessary. Given the fact that a road is crowded at some sections and is not c...

The exponential rise in wireless communication demands and allied applications have revitalized academia-industries to develop more efficient routing protocols. Wireless Sensor Network (WSN) being battery operated network, it often undergoes node death-causing pre-ma...

Routing in computer networks has played a special role in recent years. The cause of this is the role of routing in a performance of the networks. The quality of service and security is one of the most important challenges in routing due to lack of reliable methods. Routers use routing algorithms to find the best route to a particular destination. When talking about the best path, we consider p...

In this research attempts were made to estimate the in-situ stresses acting on a hydrocarbon reservoir based on routine activities of acid injection in oil reservoir. It was found that the relation between the re-opening pressure of fracture and principal in-situ stresses can be estimated using rock mechanics equations for the circular underground cavities. An appropriate relation between the m...
