Introduction Within the moss genus Timmia, three or four sections have been suggested based on morphology. Earlier studies conflicted in suggesting that T. austriaca Hedw. either displays limited phylogeographical structure includes large molecular variation with potential for geographical structure.Methods Relationships within Timmia were inferred from nuclear 26S and plastid atpB–rbcL trnL–tr...

in this study, the stochastic cell formation problem with developing model within queuing theory with stochastic demand, processing time and reliability has been presented. machine as server and part as customer are assumed where servers should service to customers. since, the cell formation problem is np-hard, therefore, deterministic methods need a long time to solve this model. in this study...

titania nanotubes (tnt) prepared by anodization of ti foils were used for water splitting in a standalone cell. the concentration polarization between the anode side (1m naoh) and cathode side (0.5 m h2so4) ensured that the water splitting reaction could take place with no external bias and separate h2 and o2 evolution could be achieved. the destruction of tnt structures under 365 nm uv irradia...

introduction: l. pneumophila is the most important cause of legionaires, disease, which is currently reported either as a nosocomial or community acquired infection. rapid and reliable diagnosis of legionella has hampered the epidemiological studies and disease control activities. in spite of good sensitivity and specificity, the culture method encountered serious shortcomings. polymerase chain...

we used qcd factorization for the hadronic matrix elements to show that the existing data, in particular the branching ratios br ( ?j/?k) and br ( ?j/??), can be accounted for this approach. we analyzed the decay within the framework of qcd factorization. we have complete calculation of the relevant hard-scattering kernels for twist-2 and twist-3. we calculated this decays in a special scale ( ...

Iris belongs toIridaceae family and it is monocotyledon. Iris is one of the important ornamental and medicinal plants. 34 iris genotypes (14 species) collected from different provinces of Iran were planted at National Institute of Ornamental Plants (NIOP) Iran. All of the species evaluated for 15 quantitative traits and 30 qualitative traits. Results showed that the highest positive correlation...

Titania nanotubes (TNT) prepared by anodization of Ti foils were used for water splitting in a standalone cell. The concentration polarization between the anode side (1M NaOH) and cathode side (0.5 M H2SO4) ensured that the water splitting reaction could take place with no external bias and separate H2 and O2 evolution could be achieved. The destructi...

Having a clear set of basic Iranian students’ legal rights could serve as a practical guideline to commitments and responsibilities of teachers, administrators, and others dealing with education. To this end, all existing legal documents related to the topic were content analyzed. The result has been a set of fourteen principle areas which can be categorized into three subsets depending on the ...
