date juice was treated by cross- flow ultra-filtration with molecular weight cut-off (mwco) of 5 kda. optimized levels of feed brix, tmp and operation time were determined as 47.13, 82.11 psi and 30 min, respectively. under such conditions, 80.94% decolourisation and 97.78 % turbidity reduction were obtained while loss of glucose and fructose were estimated to be only 3.49% and 9.62%, respectiv...

the main impetus for our research is provided by the growing interest worldwide in ultra thin silicon dioxide on silicon based nano devices. the obvious need for better knowledge in the ultra thin gate silicon dioxides, is motivated both by interests in fundamental research and phenomenology as well as by interests in possible applications, which can be found with better fitting of experimental...

a newly designed printed slot antenna is presented that incorporates variable two band-notched functions for ultra-wideband (uwb) applications. the two band notches of this coplanar waveguide (cpw) fed antenna are achieved by an m-shaped slot (mss) embedded in the radiating element and a c-shaped strip(css) close to ground plane, therefore two very narrow rejected properties in the wireless loc...

a variety of anthropometric and training characteristics have been identified as predictor variables for race performance in endurance and ultra-endurance athletes. anthropometric characteristics such as skin-fold thicknesses, body fat, circumferences and length of limbs, body mass, body height, and body mass index were bi-variately related to race performance in endurance athletes such as swim...

In [1] we uniquely introduced ultra exponential functions (uxpa) and denednext step of the serial binary operations: addition, multiplication and power.Also, we exhibited the topic of limit summability of real functions in [2,3]. Inthis paper, we study limit summability of the ultra exponential functions andprove some of their properties. Finally, we pose an unsolved problem aboutthem.

Abstract Objectives This study evaluates ultra-marathon runners’ use of goal-setting, self-talk, and imagery as strategies to help them through the challenge long-distance running. Methods In stage one, thirty-one self-professed non-runners were recruited received motivational interviewing (MI) in a group setting, examining their motivation get healthy. two, five months later, participants aske...

PURPOSE Peroxiredoxin-2 (PRDX-2) is an antioxidant and chaperone-like protein critical for cell function. This study examined whether the levels of lymphocyte PRDX-2 are altered over 1 month following ultra-endurance exercise. METHODS Nine middle-aged men undertook a single-stage, multi-day 233 km (145 mile) ultra-endurance running race. Blood was collected immediately before (Pre), upon comp...

 Leydig stromal cell tumor is a rare ovarian tumor that belongs to the group of sex-cord stromal tumors. They produce testosterone leading to hyperandrogenism. We present a 41yr old woman with symptoms of virilization and a mass of right adenex via ultra Sonography, and a rise of total and free serum testosterone. An ovarian source of androgen was suspected and a surgery performed. A diagnosis ...
