objective: lack of scientific writing skills is one major problem encountered for publication of research results of iranian scientists in accredited journals. as the result, many research projects or dissertation findings remain unpublished. this study aimed to assess the quality of writing of the “results” section of some original articles published in iranian farsi and international english ...

Focussing on preplanetary grains growth, we discuss the properties of dust aggregation driven by magnetic dipole forces. While there is no direct evidence for the existence of magnetic grains present in the solar nebula, there are reasons to assume they may have been present. We derive analytical expressions for the cross-section of two interacting dipoles. The effective cross section depends u...

an analytical nonlinear stress-strain model and a microscopic damage index for confined and unconfined concretes together with a macroscopic damage index for reinforced concrete (rc) structures under cyclic loading are proposed. in order to eliminate the problem of scale effect, an adjustable finite element computer program was generated to simulate rc structures subjected to cyclic loading. by...

Fluorometry, ion-exchange chromatography, electrophoretic separations and Fourier transform±infrared (FT±IR) spectra were used to determine and characterize amino acids and proteins in 15 di€erent beer samples. Proteins precipitated by ammonium sulfate yielded complex electrophoretic patterns. The major bands corresponded to 45±40 kDa as determined by a two-dimensional gel electrophoresis (2-DE...

Experimental Section Materials All chemicals and solvents were of analytical grade and commercially available.
