During the past decades, FRP strengthened RC structures have attracted worldwide interest in both application and research. Nowadays, as more and more infrastructures are being suffered from severe corrosions due to harsh and extreme environments, the durability of FRP strengthened RC structures has generally emerged as the most important issue in research. Thus, the paper presents the latest p...
We examined a disease outbreak of the fan mussel, Pinna nobilis (L.), in Alfacs Bay (South Ebro Delta, Spain) during period two years three zones exposed to summer salinity gradient resulting from agricultural freshwater discharges and distance open sea. Long-term monitoring was also conducted Fangar (North Delta), featuring lower salinities no evidence disease. Results showed that (37.4–35.7) ...
The characteristics of near-storm environments have been elucidated by several studies of observed soundings near reported tornadoes (Maddox 1976; Kerr and Darkow 1996), all soundings for multiple severe weather hazards during a complete year (Rasmussen and Blanchard 1998), or long-period samples of soundings associated with severe thunderstorms (Craven and Brooks 2004). Meanwhile, much attenti...
Background: Our hearing ability in space is critical for hearing speech in noisy environment and localization. The Spatial Hearing Questionnaire (SHQ) has been devised to focus only on spatial haring tasks (e.g., lateralization, distance detection and binaural detection). The aim of the present study was to determine the reliability and validity of the Persian translation of the SHQ (Spatial ...
A set of 21 cases in which an isolated supercell merged with a squall line were identified and investigated using analyses from the Rapid Update Cycle (RUC) model, archived data from the Weather Surveillance Radar-1988 Doppler (WSR-88D) network, and severe storm reports. This analysis revealed two primary environments associated with these mergers: a weak synoptic forcing, weak to moderate shea...
severe congenital neutropenia (scn) is a rare primary immunodeficiency disease. different genes are found to be associated with scn, including ela2, hax1, was, gfi1, g-csfr and g6pc3. the aim of this study was to find different gene mutations responsible for scn in iranian patients. twenty-seven patients with scn referred to immunology, asthma and allergy r...
severe congenital neutropenia (scn) is a rare primary immunodeficiency. different genes are found to be associated with scn, including ela2, hax1, was, gfi1, g-csfr. also, recently g6pc3 as a rare gene in scn has been reported. patients with g6pc3 often have cardiac and/or urogenital malformations. two patients with persistent severe neutropenia, recurrent infections and maturatio...
scid disorder is major failure of the immune system, usually genetic. the aim of this study was on mutations detection of rag1, rag2, and il7rg genes in scid cases. mutation detection was performed by pcr sequencing. our results indicated that 13 mutations were found through cases which include 4 mutations in il7r gene (t661i, i138v, t56a, c57w), 7 mutations in rag1 (w896x, w204r, m324v,...
though intravenous (iv) magnesium sulphate (mgs04) has additive effect to beta-2 agonists, its additive benefit in face of combination therapy with beta-2-agonists and ipratropium (standard therapy of severe acute exacerbation of asthma) remains unaddressed. the aim of this investigation was to evaluate the role of iv mgso4 when used as an adjunct to standard therapy of severe exacerbations of ...
