The study investigated whether there was any significant generic difference between the Research Questions (RQs) and Method sections of applied linguistics research articles (RAs) published in international and local Iranian journals. Two hundred applied linguistics RAs (100 from each group) were selected from 5 SSCI-indexed international journals and 5 Iranian Scientific-Research (Elmi-Pazhouh...

statement of problem: recurrent aphthous stomatitis (ras) is one of the most common diseases affecting the oral mucosa. many topical and systemic medications used to treat ras have adverse local and systemic effects. chamomill (kamillosan) has been shown to be an effective drug, without any noticeable side effects. purpose: the aim of present study was to assess the efficacy of a chamomill mout...

background: sediments are inseparable fractions of wetland ecosystems that work as a his-torical archive in the process of recording heavy metal aggregation changes. this study was carried out for assessing co, ni, and zn in sediment samples of mighan wetland using geo-accumulation index in 2013. methods:the sediment samples were taken from 11 stations. the samples were subjected to bulk digest...

Modern cloud infrastructures are geo-distributed. Geodistribution offers many advantages but can increase the total cloud capacity required. To achieve low latency, geo-distribution forfeits statistical multiplexing of demand that a single data center could benefit from. Geo-distribution also complicates software design due to storage consistency issues. On the other hand, geodistribution can l...

Rich geo-textual data is available online and the data keeps increasing at a high speed. We propose two user behavior models to learn several types of user preferences from geo-textual data, and a prototype system on top of the user preference models for mining and search geo-textual data (called PreMiner) to support personalized maps. Different from existing recommender systems and data analys...

The Group on Earth Observations Biodiversity Observation Network (GEO BON) has been in formal existence for three years, following several years of design and discussion. It is the realisation of the biodiversity societal benefit area envisaged in the GEO System of Systems (GEOSS). GEO BON links together existing networks, each covering particular aspects of biodiversity or parts of the world, ...

Human cells contain four homologous Ras proteins, but it is unknown whether these homologues have different biological functions. As a first step in determining if Ras homologues might participate in distinct signaling cascades, we assessed whether a given Ras guanine nucleotide exchange factor could selectively activate a single Ras homologue in vivo. We found that Ras-GRF/Cdc25Mm activates Ha...

The Ras(17N) dominant negative antagonizes endogenous Ras function by forming stable, inactive complexes with Ras guanine nucleotide exchange factors (GEFs; e.g., SOS1). We have used the growth-inhibitory phenotype of Ras(17N) to characterize two aspects of Ras interaction with GEFs. First, we used a nonprenylated version of Ras(17N), designated Ras(17N/186S), which no longer associates with th...

The PubMed database offers an extensive set of publication data that can be useful, yet inherently complex to use without automated computational techniques. Data repositories such as the Genomic Data Commons (GDC) and the Gene Expression Omnibus (GEO) offer experimental data storage and retrieval as well as curated gene expression profiles. Genetic interaction databases, including Reactome and...
