SUMMARY Advancements in microsurgical techniques as applied to perforator flaps have made harvesting flaps in a free-style manner a practical reality. A hand-held Doppler identifies sizable perforators on which flaps can be based. In free-style free flap harvesting, any region of the body can be chosen as a donor site as long as there is an audible pulsatile Doppler signal. The value of the fre...

This document provides a brief summary estimate of Galactic free-free emission and Hα emission and their relationship. Particular emphasis is placed on estimating the potential freefree emission in the region of significant confusion for CMB anisotropy measurements. Existing x-ray, ultraviolet and Hα emission provide limits on the radio free-free emission and vice versa. These limits are genera...

To a real Hilbert space and a one-parameter group of orthogonal transformations we associate a C∗-algebra which admits a free quasi-free state. This construction is a freeprobability analog of the construction of quasi-free states on the CAR and CCR algebras. We show that under certain conditions, our C∗-algebras are simple, and the free quasi-free states are unique. The corresponding von Neuma...

the distribution of the allophones of /?/in certain contexts involves free variation and gradient preferences. an organized survey was conducted to elicit the judgments of 37 native persian speakers concerning the well-formedness of /?/allophonic behavior in five different phonological positions. the results showed that the differences in judgment between the various categories are not just t...

let h be a finite dimensional complex hilbert space, b(h)+ be the set of all positive semi-definite operators on h and phi is a (not necessarily linear) unital map of b(h) + preserving the entropy-gibbs transformation. then there exists either a unitary or an anti-unitary operator u on h such that phi(a) = uau* for any b(h) +. thermodynamics, a branch of physics that is concerned with the study...

some of the adamantane properties were calculated in this study. chemical shift, free energy ofsolvation, free energy of cavity formation, henry's law constant, and other properties ofadamantane in dry phase, three solvents and three temperatures have been calculated with abinitio method base on density functional theory (dft) at b3lyp/6-31g, b31yp/6-31g*, b3lyp/6-31+g* and b3lyp/6-31++g** leve...

the aim of this study was to investigate the range utilization of rhode island red hens, grazing outdoor (under tropical conditions) and to scan their activities inside the house as well as during their outdoor visits. the activities of rir hens, raised in indoor floor pens connected with outdoor areas covered with natural vegetation, were scanned and recorded individually within 15 minute inte...

bean yellow mosaic virus (bymv, potyvirus, potyviridae) causes serious disease in gladiolus spp. in this work, the possibility of obtaining bymv free plant material from virus infected gladiolus corms was studied. thermotherapy, meristem-tip culture and combination of both techniques on infected corms/meristem-tip explants (0.5–1 mm in length) resulted in bymv elimination up to 15.38, 78.04 and...

dodecylbenzenesulfonic acid (dbsa) was used as an efficient, cheap and stable brønsted catalyst for acetylation of alcohols and phenols and formylation of alcohols under solvent-free conditions. various primary, secondary and tertiary alcohols were acetylated with acetic anhydride as an acetylating agent under solvent-free conditions in the presence of catalytic amount of dbsa at room temperatu...
