desert truffles, hypogeous pezizales (ascomycota), are difficult to identify due to evolutionary convergence of morphological characters among taxa that share a similar habitat and mode of spore dispersal. in this paper we document the presence of picoa lefebvrei (pat.) maire (=phaeangium lefebvrei) in iran and use phylogenetic analysis of the its and 28s rdna to show that this species belongs ...

bioleaching is the extraction of metals from their ores through the use of microorganisms. inthis process, the use of native bacteria leads to achieve more yields of metals. so, in the presentstudy, native sulfur-oxidizing bacterium in potentiality of uranium extraction was isolated fromghachin mine in iran and identified by partial gene sequencing. for this purpose, the watersamples were colle...

Data capture technologies such as RFID promise customer centric global service supply chains, but simultaneously threaten data overload. We argue that novel approaches to information management are required to successfully manage the data from sensor-based data capture technologies and to integrate them into successful inter-organizational service supply networks. We question the degree to whic...

A comparative review is presented of available technologies suitable for automatic reading of patient identification bracelet tags. Existing technologies' backgrounds, characteristics, advantages and disadvantages, are described in relation to their possible use by public health care centers with budgetary limitations. A comparative assessment is presented of suitable automatic identification s...

This paper presents a Scenario-Based Adaptive Service Framework, where we can provide more adaptive service scenarios among highly correlated business applications. Individual services are seamlessly integrated into a framework by registering scripts, written in XML infrastructure language, called the XLogic, to the middleware platform, the XCREAM (XLogic Collaborative RFID/USN-enabled Adaptive...

In this concept paper, we study the complex innovation of Radio Frequency Identification Systems (RFID) in context of their functional value. The purpose of this research is to provide an interpretation of functionality as presented by contemporary RFID systems and organized in the form of a functional matrix that demonstrates RFID mainstream applications. The fundamental functions are broken d...

identification, authentication and quality control are essential to ensure safety, therapeutic potency, efficacy and reproducible quality of herbal medicines. the aim of this study is to use taxonomic method for authentication of traditional herbal drugs which are commonly sold in herbal shops in iran. in this regard, twenty-seven cases of herbal drugs suspected to be adulterated were investiga...

background and objectives: the genus malassezia contains an expanding list of lipophilic yeasts involve in the etiology of various superficial fungal infections. pityriasis versicolor (pv) is the most prevalent malassezia -related infection distributed worldwide. in the present study, clinical and epidemiological features of the genus malassezia are discussed with special focus on pv in iran. m...

due to the epidemiological alteration in distribution of candida species as well as significant increasing trend of either intrinsic or acquired in resistance of some of these fungi, the precise identification of candida species is necessary for effective antifungal therapy and also for prevention of nosocomial infections. pcr-rflp method is indicated to be a reliable, rapid and simple techniqu...
