Polymerisable octahedral rhenium cluster complexes as precursors for photo/electroluminescent polymers

New polymerisable photoluminescent octahedral rhenium cluster complexes trans-[{Re₆Q₈}(TBP)₄VB)₂] (Q = S or Se; TBP – p-tert-butylpyridine; VB – vinyl benzoate) have been synthesised, characterised and used to construct rhe-nium cluster-organic polymer hybrid materials. These novel polymer systems are solution-processable and the rhenium clusters retain their photoluminescent properties within the polymer environment. Notably, when the rhenium cluster complexes are incorporated into the matrix of the electroluminescent polymer poly(N-vinylcarbazole), the resultant cluster polymer hybrid combined properties of both components and was used successfully in the construc-tion of a polymer light emitting diode (PLED). These prototype devices are the first PLEDs to incorporate octahedral rhenium clusters and provide the first direct evidence of the electroluminescent properties of rhenium clusters and indeed, to the best of our knowledge, of any member of the family of 24-electron hexanuclear cluster complexes of molybdenum, tungsten or rhenium

A WIDE DISTRIBUTION OF A NEW VRN-B1c ALLELE OF WHEAT TRITICUM AESTIVUM L. IN RUSSIA, UKRAINE AND ADJACENT REGIONS: A LINK WITH THE HEADING TIME AND ADAPTIVE POTENTIAL

The adaptation of common wheat (T. aestivum L.) to diverse environmental conditions is greatly under the control of genes involved in determination of vernalization response (Vrn-1 genes). It was found that the variation in common wheat heading time is affected not only by combination of Vrn-1 homoeoalleles but also by multiple alleles at a separate Vrn-1 locus. Previously, we described the Vrn-B1c allele from T.aestivum cv. 'Saratovskaya 29' and found significant differences in the structure of the first (1st) intron of this allele when compared to another highly abundant Vrn-B1a allele, specifically, the deletion of 0.8 kb coupled with the duplication of 0.4 kb. We suggested that the changes in the intron 1 of Vrn-B1c allele caused earlier ear emergence in the near-isogenic line and cultivars, carrying this allele. In this study we investigate the distribution of the Vrn-B1c allele in a wide set of spring wheat cultivars from Russia, Ukraine and adjacent regions. The analysis revealed that 40% of Russian and 53% of Ukranian spring wheat cultivars contain the Vrn-B1c allele. The high distribution of the Vrn-B1c allele can be explained by a frequent using of 'Saratovskaya 29' in the breeding process inside the studied area. From the other hand, the predominance of the Vrn-B1c allele among cultivars cultivated in West Siberia and Kazakhstan may be due to the selective advantage of this allele for the region where there is a high risk of early fall frosts

FEATURES OF THE EDUCATIONAL PROCESS FOR CHILDREN WITH ATTENTION DEFICIT HYPERACTIVITY DISORDER

Наличие в современном мире проблем, связанных с экологией, экономикой, социальной неуравновешенностью, а также кризис семейных ценностей приводят к тому, что все больше людей испытывают проблемы психо-неврологического характера. Более всего такого вида расстройствам подвержены дети, так как их психика еще не сформирована, этим можно объяснит возросший процент детей с синдромом дефицита внимания с гиперактивностью. Дети с СДВГ испытывают большие трудности в обучении и требуют особого подхода к ним от педагогов. В данной статье описаны методы, помогающие сделать процесс обучения более плодотворным для детей с СДВГThe presence in the modern world of problems related to the environment, economy, social instability, as well as the crisis of family values lead to the fact that more and more people experience problems of a psycho-neurological nature. Children are most susceptible to this type of disorder, since their psyche is not yet formed, this can explain the increased percentage of children with attention deficit hyperactivity disorder. Children with ADHD experience great difficulties in learning and require a special approach to them from teachers. This article describes methods that help make the learning process more fruitful for children with ADH
