Inspired by recent developments in particle physics, the so-called brane world cosmology seems to provide an alternative explanation for the present dark energy problem. In this paper, we use the estimated age of high-z objects to constrain the value of the cosmological parameters in some particular scenarios based on this large scale modification of gravity. We show that such models are compat...

This document describes the RC encryption algorithm a fast symmetric block cipher suitable for hardware or software imple mentations A novel feature of RC is the heavy use of data dependent rotations RC has a variable word size a variable number of rounds and a variable length secret key The encryption and decryption algorithms are exceptionally simple

The Rauhut-Currier (RC) reaction represents an efficient method for the construction of carbon-carbon bond in organic synthesis. However, the RC reactions involving allenoate substrates are very rare, and in particular, asymmetric intramolecular RC reaction of allenoates is yet to be discovered. Here, we show that the intramolecular RC reaction proceeds smoothly in the presence of 1 mol% β-ICD,...

The effect of somatostatin analogue RC-160 on the growth of hepatic metastases of colon cancer was investigated in rats using magnetic nes onance imaging. Experimental liver metastatic tumors were established in syngeneic BDIX rats after intrasplenic injection of DHD/K12 colon adenocarcinomacells. Each rat with implanted liver tumors receiveds.c. injections of somatostatin analogue RC-160 (50 @...

Double blind study presents clinical and laboratory estimation of root canal system (RC) cleaning by endodontic treatment of apical periodontitis by means of galvanophoresis of hydroxide copper-calcium (GP HCC). In 60 patients the amount and composition of RC fluid from incisors and canines by GP HCC were estimated within 2 weeks with three different galvano-pair and the efficiency of RC decont...

The present study examined the developmental relationship between morphological awareness (MA) and reading comprehension (RC) using a 2-year and four-wave cross-lagged design with a sample of 149 Chinese children (80 males and 69 females). We measured children's MA, word reading (WR), and RC from T1 to T4, in addition to phonological awareness, vocabulary knowledge, and general cognitive abilit...

Studies have suggested that reading speed (RS) or fluency should be a component of reading comprehension (RC) models. There is also evidence of a relationship between RS and RC. However, some questions remain to be explored, as the changes in such a relationship may be a function of development. In addition, while there are studies published with English speakers and learners, less evidence exi...

BACKGROUND In a retrospective study of Southwestern Oncology Group (SWOG)-S8710/INT-0080 (radical cystectomy [RC] alone vs 3 cycles of neoadjuvant chemotherapy [NC] with methotrexate, vinblastine, doxorubicin, and cisplatin before RC for bladder cancer), factors found to be associated with improved overall survival (OS) included pathologic complete response, defined as P0; treatment with NC; co...

Frog ribonucleases have been demonstrated to have anticancer activities. However, whether RC-6 ribonuclease exerts anticancer activity on human embryonal carcinoma cells remains unclear. In the present study, RC-6 induced cytotoxicity in NT2 cells (a human embryonal carcinoma cell line) and our studies showed that RC-6 can exert anticancer effects and induce caspase-9 and -3 activities. Moreove...
