We consider random walk in elliptic i.i.d. random environment in dimension greater than or equal to 4, satisfying the bal-listicity condition (T ′). We show that for every ǫ > 0 and n large enough, the annealed probability of linear slowdown is bounded above by exp`− (log n) d−ǫ´. This is almost matching the known lower bound of exp`− C(log n) d ´ , and significantly improves previously known u...

Polyarginine-containing peptides represent potent inhibitors of furin, a mammalian endoprotease that plays an important role in metabolism, activation of pathogenic toxins, and viral proliferation. The therapeutic use of D-polyarginines is especially interesting because they are not cleaved by furin and possess inhibitory potency almost equal to L-polyarginines. In this study we attempted to de...

Let X be an infinite set of regular cardinality. We determine all clones on X which contain all almost unary functions. It turns out that independently of the size of X, these clones form a countably infinite descending chain. Moreover, all such clones are finitely generated over the unary functions. In particular, we obtain an explicit description of the only maximal clone in this part of the ...

A well known consequence of the Borsuk-Ulam theorem is that if the d-dimensional sphere S is covered with less than d + 2 open sets, then there is a set containing a pair of antipodal points. In this paper we provide lower and upper bounds on the minimum number of open sets, not containing a pair of antipodal points, needed to cover the d-dimensional sphere n times, with the additional property...

In present study, molecular dynamics simulation of Cadmium (II), Lead (II) and Copper (II) removal from aqueous electrolyte solutions using the ion-exchange process with the zeolite particles was done. The results showed that, most of the particles had the highest affinity of ion exchanging with Lead (II) and the lowest affinity with Copper (II). The calculated mean ion-exchange ratios showed t...

Experiments in a large-scale flow loop provide an example of a somewhat increased corrosion rate under multiphase flow conditions caused by a low concentration of H2S in a CO2 saturated environment. Under operating conditions that prevent scale formation, the addition of 3ppm H2S in the gas phase increased the corrosion rate of AISI C 1018 and API 5L X-65 carbon steels, while the addition of H2...

turmeric ( curcuma longa l.) is a perennial rhizomatous plant from the family of zingibraceae, native in south asia. the main components of turmeric are curcuminoids and essential oil which are responsible for turmeric characteristic such as odor and taste. due to the large areas of saline land in iran and less information related to cultivation of turmeric, in this research, the effect of sali...
