sorption reactions in many heterogeneous systems are important. adsorption is a time dependent process and knowing the adsorption rate is essential for designing, evaluating and recovering the adsorbents. at the present study, an ammonium adsorption kinetic experiment by some soils series of golestan provice, which is varying in mineralogical and textural properties was conducted using solution...

This paper demonstrates the efficient method of tuning PI controller parameters by comparing different tuning rules. The method implies an analytical calculation of the controller gain , Integral time for a PI controlled system which is modeled to be a First Order Plus Dead Time (FOPDT) process. A bench mark non linear system, conical tank is considered for study for which the identified transf...

Xylariaceous fungi are typically saprobes, but are also commonly isolated as endophytes and some species are pathogens. Two species of Lopadostoma (Xylariaceae, Xylariales) are reported for the first time from Iran. L. dryophilum was found from dead branches of Quercus sp. in East Azerbaiejan and L. fagi from dead branches of Fagus sp. in Ardabil province. Based on morphology and sequence data ...

We revisit phase transitions in Twin Higgs (TH) models. show that strong first-order (FOPTs) can occur provided appropriate source of $\mathbb{Z}_2$ symmetry breaking between the twin and Standard Model (SM) sectors is present. found FOPTs two classes First: with hard scalar potential allowing for FOPT. Second: broken by enhanced Yukawa couplings leptons. also considered supersymmetric UV compl...
