A phylogenetic analysis of Astragalus sect. Alopecuroidei based on nrDNA ITS as well as morphological character data is presented. A total of fifty informative morphological characters were analyzed to reconstruct phylogenetic relationships for 23 taxa of the sect. Alopecuroidei and two species of sect. Laxiflori plus A. sieversianus and A. caryolobus as outgroups. The present analysis revealed...
The Born-Oppenheimer approximation [1] can be used whenever the hamilto..ian of a fast system depends on the coordinates of a slow system . In some textbooks, the problem is solved by freezing the coordinates of the slow system and solving the hamiltonian of the fast system; then the energy of the fast system enters the effective hamiltonian for the slow system as a potential energy term. This ...
The Jaramillo Event was originally defined by Doell and Dalrymple in 1966 on the basis of K^Ar ages from sanidine in the normally, transitionally and reversely magnetized rhyolite domes named Cerro del Abrigo, Cerro Santa Rosa I and Cerro Santa Rosa II, respectively, that erupted following collapse of the archetypal Valles Caldera, New Mexico. We have collected new paleomagnetic data from the t...
در بررسی تاکسونومیکی بر روی جنس Hieraciumدر ایران که بر اساس مطالعات نمونه های هرباریومی و جمع آوری شده صورت گرفت، H. ×sintenisiiو H. ×pannoniciforme از بخش sect. Praealtina، H. pollichia از بخش sect. Vulgata و H. echioides Lumn. subsp. echioides از بخش sect. Echinina برای اولین بار از ایران گزارش می شوند. گونه‌های H.×procerigenum با H.×auriculoides و H. ×woronowianum با H. ×maschukenseمتر...
Cortinarius is the largest genus of ectomycorrhizal fungi worldwide. Recent molecular studies have shown high levels of morphological homoplasy within the genus. Importantly, DNA phylogenies can reveal characteristics that have been either over- or underemphasized in taxonomic studies. Here we sequenced and phylogenetically analysed a large set of pan-European and North American collections tax...
In systemic mastocytosis (SM), clinical problems arise from factor-independent proliferation of mast cells (MCs) and the increased release of mediators by MCs, but no human cell line model for studying MC activation in the context of SM is available. We have created a stable stem cell factor (SCF) -dependent human MC line, ROSA(KIT WT), expressing a fully functional immunoglobulin E (IgE) recep...
Rosa centifolia and Rosa gruss an teplitz distillation waste biomass was immobilized using sodium alginate for Pb(II) uptake from aqueous solutions under varied experimental conditions. The maximum Pb(II) adsorption occurred at pH 5. Immobilized rose waste biomasses were modified physically and chemically to enhance Pb(II) removal. The Langmuir sorption isotherm and pseudo-second-order kinetic ...
We conducted a phylogenetic analysis to characterize relationships among Bromus and test the monophyly of five of the seven morphologically distinct groups within Bromus (Poaceae: Pooideae) that have been treated as sections, subgenera, or genera. We sequenced the chloroplast trnL (UAA) intron, the 3!-end of the chloroplast ndhF gene, and the internal transcribed spacers (ITS) of the nuclear ri...
