the catalyst pt-ta supported on 7-alumina was prepared by impregnation with solution containing compoundsof ii21k1.0. and ta205 the pt concentration was kept constant at 0.2 vet% while the concentration of thetantalum was 0,4 wt%. the activity and selectivity of catalyst were determined under conditions at 450-500 °cand 15-30 atm.. with molar ratio h2/c[h,e5 and wh=1.5ml/h for converted n-hepta...

The influence of the thyroarytenoid (TA) and cricothyroid (CT) muscle activation on vocal fold stiffness and eigenfrequencies was investigated in a muscularly controlled continuum model of the vocal folds. Unlike the general understanding that vocal fold fundamental frequency was determined by vocal fold tension, this study showed that vocal fold eigenfrequencies were primarily determined by vo...

Layer-by-layer (LbL) assembled films have been exploited for surface-mediated drug delivery. The drugs loaded in the films were usually released via diffusion or the degradation of one of the film components. Here we demonstrate that drug release can also be achieved by exploiting the dynamic nature of hydrogen-bonded LbL films. The films were fabricated from tannic acid (TA), a model polypheno...

to shorten the dormancy period of potato minitubers and to increase a tuber's capacity to be planted sooner after being harvested, an experiment was conducted at pishtaz tissue culture company in karaj, using factorial experiment on the basis of a completely randomized design with three replications. the first factor was comprised of cultivars (agria, marfona and burren), the second minitu...

Here, we show that a small-molecule activator of telomerase (TA-65) purified from the root of Astragalus membranaceus is capable of increasing average telomere length and decreasing the percentage of critically short telomeres and of DNA damage in haploinsufficient mouse embryonic fibroblasts (MEFs) that harbor critically short telomeres and a single copy of the telomerase RNA Terc gene (G3 Ter...

OBJECTIVES/HYPOTHESIS Laryngeal adductor muscle dysfunction is a common cause of voice disorders. Reconstitution of adductor muscle function is often the target of therapy, but the effects of these muscles on voice production remain to be fully understood. This study investigated the differential roles of thyroarytenoid (TA) and lateral cricoarytenoid (LCA) muscles on voice production. STUDY ...

The main purpose of this paper is to compare the actual transpiration rates from tomato crop, as measured at leaf scale and estimated by a macroscopic approach in an agro-hydrological model, named FLOWS-HAGES, under variable soil properties water availability. To aim, sixteen plots were cultivated with tomatoes Metaponto, Southern Italy. Soil hydraulic (SHP) obtained using fast in-situ characte...
