Armenian grapevines: cytoembryological, morphological and chemical analysis

The objectives of our study was to phenotype Armenian grapevines on the base of cytoembryological, morphometric and phenolic content analysis of 10 wine and 10 table cultivars (Vitis vinifera L.). The presented results suggest that Armenian table grape cultivars have higher level of abnormalities in the process of seed formation than wine cultivars. However, during ovule development, the observed differences between table and wine varieties were not significant. The berry morphometric analysis demonstrated that table cultivars formed significantly larger and heavier berries than wine cultivars. The obtained results show that wine grapes contained significantly higher phenol concentrations than table grapes, in both colored and white grapevine cultivars. The study of phenol composition, an important chemical descriptor in grapevine phenotyping, provides oenological information useful to improve the wine quality. Cultivar characterization could be used as marker for the selection of table and wine grape breeding programs. These results will be upgraded in the database for Armenian grapevine varieties. In future Armenian germplasm will be compared with datasets of neighboring countries, to determine the varietal origins relationships

Non-exciting wakefield structured bunches in a one-dimensional plasma model

A model of one-dimensional (1D) cold plasma with an external train of rigidly structured bunches with diverse charges has been introduced. In this model, a solution that cancels the wakefield after the train is found. The density of such bunches can be much greater than the density of the plasma, and a high amplitude electrical field arising inside the train can be used for charged-particle acceleration. In addition, analytical and numerical simulations have been performed

The article is devoted to improvement of methodical training of future officers and their capacities for individual activities in the context of activation of the subject area of pedagogy. According to the concept of I. E. Akulov, V. I. Baydakov, A. G. Vasilyev, methodical training is seen as a set of training activities aimed at improving the skills of officers, warrant officers (midshipmen), sergeants (foremen) in the training of subordinates. Methodical training is an integral part of the commander’s training. The article deals with the functional and personal approaches to rendering the term "methodical preparation" in modern science, as well as the concept of methodical preparation of future officers to arrangement of individual education of soldiers in the unit. Methodical readiness of the cadet to the organization of self-education of the military personnel is a component of structure of professional training of the future officer to service and fighting activity. Advantages and efficiency of methodical readiness of the future officer to the organization of self-education of the military personnel as quality of the personality are analyzed. The urgency of self-educational activity and its priority in development of the serviceman as the subject of professional self-realization is revealed. The purpose of methodical preparation of the future officer to the organization of self-education of the military personnel consists in activation of the psychological and pedagogical knowledge, abilities and skills allowing to use effectively modern technologies of self-educational activity of cadets providing the dominating orientation and motivation in realization of the purposes and tasks of pedagogical maintenance of individual education of the military personnel in military professional activity. The article highlights a model of methodical preparation of future officers of the national guard to individual education of soldiers, reflecting the internal prerequisites that determine the possibility of a deeply conscious, thoughtful, creative nature of work on yourself. The final result of individual education depends to great extent on the level of their development. That is why it is important to focus on formation and development of these internal prerequisites. in individual education of military staffСтатья посвящена повышению качества методической подготовки будущих офицеров к организации самообразования военнослужащих в контексте активизации предметной области педагогики. Согласно концепту И.Е. Акулова, В. И. Байдакова, А.Г. Васильева, «методическая подготовка – комплекс учебных мероприятий, направленных на повышение мастерства офицеров, прапорщиков (мичманов), сержантов (старшин) в обучении и воспитании подчиненных. Методическая подготовка является составной частью командирской подготовки» [1, с. 28]. В статье рассмотрены функциональный и личностный подходы к пониманию термина «методическая готовность» в современной науке, а также сформулировано понятие методической готовности будущих офицеров к организации самообразования военнослужащих в подразделении.

Armenian national grapevine collection: Conservation, characterization and prospects

The general strategy for grapevine genetic resources conservation in Armenia encompasses the collection of the still existing diversity and the use of protection techniques to minimize the losses over time. Being studied mainly by ampelography, the genetic diversity of Armenian grapevine needs to be re-investigated in accordance with modern requirements and international scales. The purpose of the presented research was the first large-scale molecular characterization of Armenian grape varieties by molecular methods using a set of 24 simple sequence repeat (SSR) markers encompassing the nine SSR markers recommended by the European project GrapeGen06. The obtained results indicate the uniqueness of the major part of the investigated varieties and reveal a substantial level of genetic variation within the Armenian grapevine. Based on the realized large-scale investigation a true-to-type inventory of Armenian grape germplasm will be realized and documented in theVitis International Variety Catalogue and in the European Vitisdatabase. The next step having strategic importance in terms of conservation of grape genetic resources in Armenia will be establishment of the first ArmenianVitis database with multi-crop passport description of all varieties preserved in grape collection

Observation of Lambda H-4 hyperhydrogen by decay-pion spectroscopy in electron scattering

At the Mainz Microtron MAMI, the first high-resolution pion spectroscopy from decays of strange systems was performed by electron scattering off a Be-9 target in order to study the ground-state masses of Lambda-hypernuclei. Positively charged kaons were detected by a short-orbit spectrometer with a broad momentum acceptance at zero degree forward angles with respect to the beam, efficiently tagging the production of strangeness in the target nucleus. In coincidence, negatively charged decay-pions were detected by two independent high-resolution spectrometers. About 10^3 pionic weak decays of hyperfragments and hyperons were observed. The pion momentum distribution shows a monochromatic peak at p_pi ~ 133 MeV/c, corresponding to the unique signature for the two-body decay of hyperhydrogen Lambda H-4 -> He-4 + pi-, stopped inside the target. Its binding energy was determined to be B_Lambda = 2.12 +- 0.01 (stat.) +- 0.09 (syst.) MeV with respect to the H-3 + Lambda mass

Professional Learning Through Everyday Work: How Finance Professionals Self-Regulate Their Learning

Professional learning is a critical component of ongoing improvement and innovation and the adoption of new practices in the workplace. Professional learning is often achieved through learning embedded in everyday work tasks. However, little is known about how professionals self-regulate their learning through regular work activities. This paper explores how professionals in the finance sector (n-30) self-regulate their learning through day-to-day work. Analysis focuses on three sub-processes of self-regulated learning that have been identified as significant predictors of good self-regulated learning at work. A key characteristic of good self-regulation is viewing learning as a form of long-term, personalised self-improvement. This study provides a foundation for future policy and planning in organisations aiming to encourage self-regulated learning
