در این تحقیق دو مبحث مورد بررسی قرار می گیرد. فصل اول، به رفتار سالیتون معادله سینوسی-گوردون دوگانه(double sine-gordon ) در حضور پتانسیل خارجی پرداخته می شود. پتانسیل خارجی به دو مدل به لاگرانژی سالیتون اضافه می شود. به طور تحلیلی معادله حرکت سالیتون در این دو مدل به روش مختصه جمعی حل می گردد. در نهایت پیش بینی های تحلیلی این دو مدل با نتایج شبیه سازی عددی مقایسه می شود. این مقایسه نشان می ...

On the basis of lithium electrolyte mechanism, modified glassy polymers were developed by adding salts to poly(methyl methacrylate) (PMMA). This review summarizes how rheological and mechanical properties PMMA changed introducing various salts: perchlorate (LiClO4), trifluoroacetate (LiCOOCF3), trifluoromethanesulfonate (LiCF3SO3), nonafluorobutanesulfonate (LiC4F9SO3), bromide (LiBr). It was f...

These studies were undertaken to examine whether an antagonism between vasopressin and prostaglandin occurs in vivo in the mammalian kidney. All experiments were performed in steroid-replaced hypophysectonized dogs undergoing a water diuresis. In the first group of studied the effect of two consecutive intravenous doses (100 mU) of vasopressin was examined. The second dose of vasopressin was pr...

The photodissociation dynamics of small I-(H2O)n(n=2-5) clusters excited to their charge-transfer-to-solvent (CTTS) states have been studied using photofragment coincidence imaging. Upon excitation to the CTTS state, two photodissociation channels were observed. The major channel (approximately 90%) is a two-body process forming neutral I+(H2O)n photofragments, and the minor channel is a three-...

In this paper, the performance of the operational Level 2 MIPAS processor for offline data (versions 4.61 and 4.62) in the presence of cloud is examined. Using simulations of typical cloud scenarios, based on MIPAS cloud statistics for the tropics, the impact of varying cloud influence at 12 km and the tangent altitude above (i.e. 15 km) is investigated. It is found that with increased cloud pr...

To understand the initial hydration processes of MgCl2, we measured photoelectron spectra of MgCl2(H2O)n- (n = 0-6) and conducted ab initio calculations on MgCl2(H2O)n- and their neutral counterparts up to n = 7. A dramatic drop in the vertical detachment energy (VDE) was observed upon addition of the first water molecule to bare MgCl2-. This large variation in VDE can be associated with the ch...

The effect of H2O on the catalytic reduction of SO2 and NO on La2O2S was studied using temperature-programmed reaction coupled with fast mass spectrometry, powder X-ray diffraction and X-ray photoelectron spectroscopy. It is found that La2O2S can be completely and irreversibly deactivated in the presence of H2O at 700°C when NO/SO2 is sufficiently high (~1.0). This is caused by the formation of...

Leaf-level CO2 assimilation (A(area)) can largely be predicted from stomatal conductance (g(s)), leaf morphology (SLA) and nitrogen (N) content (N(area)) in species across biomes and functional groups. The effects of simulated global change scenarios, increased summer monsoon rain (+H2O), N deposition (+N) and the combination (+H2O +N), were hypothesized to affect leaf trait-photosynthesis rela...
