The aim of the present study was to analyse sequences of 16S-23S internal transcribed spacer regions of different Geobacillus species, identify structural elements of these regions and evaluate the possibility to use these structural elements in the taxonomy of the genus Geobacillus. GEOBAC-PCR was used in order to obtain 16S-23S rRNA internal transcribed spacer sequences. Certain structural el...

BACKGROUND The application of spacer gel represents a promising approach to reliably spare the rectal frontal wall during particle therapy (IJROBP 76:1251-1258, 2010). In order to qualify the spacer gel for the clinical use in particle therapy, a variety of measurements were performed in order to ensure the biological compatibility of the gel, its physical stability during and after the irradia...

We observe a strong thermally-controlled magnon-mediated interlayer coupling of two ferromagnetic layers via an antiferromagnetic spacer in spin-valve type trilayers. The effect manifests itself as field-induced coherent switching the ferromagnets, which can be controlled by varying temperature and thickness. explain observed behavior due to hybridization ferro- antiferro-magnetic magnon modes ...

PURPOSE To point out the advantages and drawbacks of high-dose rate brachytherapy in the treatment of mobile tongue cancer and indicate the clinical importance of modular lead-lined spacers when applying this technique to patients. METHODS First, all basic steps to construct the modular spacer are shown. Second, we simulate and evaluate the dose rate reduction for a wide range of spacer confi...

In this paper, we describe the second-order nonlinear optical properties of a series of 1,3-dithiole-based electron donor-acceptor systems incorporating proaromatic donor and spacer groups. Modification of the proaromaticity of the quinoid spacer gives rise to NLO-phores with mubeta values ranging from -2000 x 10(-)(48) esu to +3000 x 10(-)(48) esu. Quite surprisingly, compounds with a p-benzoq...

From a rRNA repeating unit (9.1 kbp) of mustard we have The DNA was sequenced according to the method of Maxam sequenced the first internal transcribed spacer, the 5.8S rRNA and Gilbert gene, and the second internal transcribed spacer [1]. Here, we present the nucleotide sequence of a 5500 bp fragment containing the 3 ' end terminus of the 25S gene (486 bp), the intergenic spacer REFERENCES (32...

Membrane fouling is a major drawback of reverse osmosis (RO) membrane filtration as it negatively affects the quantity and quality of the permeate and lifespan of the membrane. Spacer plays a pivotal role in hydrodynamics of the membrane channel thus influencing the membrane fouling. In this study, a series of novel sinusoidal spacers that can form unobstructed sinusoidal membrane channels were...

A series of sequence changes in the spacer region of the FLP recombination target (FRT) site are presented which drastically reduce site function without affecting recognition by the FLP protein. The effects follow a pattern which indicates that two structural features of the FRT site are essential for site function: a pair of pyrimidine tracts arranged in a palindrome and a predominance of AT ...
