we investigate the temperature-dependences of the Brillouin frequency shift in three different kind of single-mode fibers using a heterodyne method for sensing temperature. Positive dependences coefficients of 0.77, 0.56 and 1.45MHz/0C are demonstrated for 25 km long single-mode fiber, 10 km long non-zero dispersion shifted fiber and 100 m photonic crystal fiber, respectively. The results indic...

the sscp technique is based on the appearance of new “refolding” conformations during electro-phoresis due to mutation. in order to develop a simple, non-radioactive sscp analysis method so that it can reliably detect single nucleotide changes in pcr products up to 500 bp in length, extensive optimisation trials were performed . the best separation of sscp bands of pcr products up to 500 bp in ...

objective:glioblastoma is an invasive tumor of the central nervous system. epigenetic therapy of cancer is potentially very useful in reversing some of cancer defects due to reversibility of epigenetic alterations. meg3 is a tumor suppressor long non-coding rna (lncrna) that expresses in the majority of normal tissues. methylation of the meg3 promoter region elicits a decrease in its expression...

the studies carried out over 2010-13 involved a static field experiment initiated in 1999 at brody research station of the poznan university of life science, poland. the soil tillage systems for winter wheat were compared on a soil classified as albic luvisols. the aim of experiments was to evaluate impact of ploughless soil tillage on some soil physical, chemical, biological properties and win...

introduction: non-ossifying fibroma (nof) is a relatively common benign and non-neoplastic lesion in long bones of children and adolescents. as far as very few cases of nof have been reported in jaws and what was managed to be found regarding all reported cases having occurred only in the mandible, in this article we are going to report a case of maxillary nof in a 38-year-old female.

this paper investigates the short- run and long-run effects of government size and exports on the economic growth of iran as a developing oil export based economy for the period of 1974 - 2008 using an autoregressive distributed lags (ardl) framework. a modified form of feder (1982) and subsequently ram’s (1986) model has been applied to include both government size and exports in growth equati...
