Received: February 1st, 2022 ; Accepted: March 27th, 2022 ; Published: April 27th, 2022 ; Correspondence: [email protected] and anatomical features of new cultivars with photosynthesis of C3 (Actinidia kolomikta (Rupr. & Maxim.) Maxim. cv. ‘Narodnaya’) and C4 (Amaranthus tricolor L. cv. ‘Valentina’) were established by light and scanning electron microscopy, as well as energy-dispersive analysis. The leaf lamina of Actinidia kolomikta cv. ‘Narodnaya’ has a dorsoventral anatomical structure, anomocytic stomata on the abaxial epidermis and two types of trichomes: multicellular, uniseriate hairs and multicellular bristle-like protrusions, containing raphids. The needle-like raphides are located in subepidermal layers along the veins. A vascular system of petiole consists of two upper concentric bundles and the crescentic vascular strand. A starch sheat is present. Raphides (needle-shaped and rectangular) are located in phloem and cortical parenchyma cells, contain Ca, K, Mg, P and Si. The leaf lamina of Amaranthus tricolor cv. ‘Valentina’ have the kranz-anatomy, dorsiventral mesophyll and contain druses. Betacyanins are concentrated in the epidermis and mesophyll, but are not present in the bundle sheath. The number of vascular bundles in petioles is odd-numbered and variable (from 5 to 13). Trichomes are multicellular, uniseriate, ending in a large oval cell. Cells with betacyanins are present in the epidermis cortex, and, rarely, the collenchyma and phloem of the petiole. Cells with betaxanthins are absent. A starch sheat is brightly pigmented with betacyanins. The crystall sand is deposited in the parenchyma cells of the cortex and pith of the petiole and contains Ca (mainly) and K oxalates. Druses in the leaf lamina additionally contain Mg and P

Bandwidth-controlled Mott transition in κ−(BEDT−TTF)2Cu[N(CN)2]BrxCl1−x\kappa-(BEDT-TTF)_2 Cu [N(CN)_2] Br_x Cl_{1-x} I. Optical studies of localized charge excitations

Infrared reflection measurements of the half-filled two-dimensional organic conductors $\kappa$-(BEDT-TTF)$_2$Cu[N(CN)$_{2}$]Br$_{x}$Cl$_{1-x}$ were performed as a function of temperature ($5 {\rm K}<T<300$ K) and Br-substitution ($x=0$, 40%, 73%, 85%, and 90%) in order to study the metal-insulator transition. We can distinguish absorption processes due to itinerant and localized charge carriers. The broad mid-infrared absorption has two contributions: transitions between the two Hubbard bands and intradimer excitations from the charges localized on the (BEDT-TTF)$_2$ dimer. Since the latter couple to intramolecular vibrations of BEDT-TTF, the analysis of both electronic and vibrational features provides a tool to disentangle these contributions and to follow their temperature and electronic-correlations dependence. Calculations based on the cluster model support our interpretation.Comment: 12 pages, 12 figure

Structural Investigations of Li1.5Al0.5Ge1.5(PO4)3 glass-ceramics by Solid State NMR

NASICON-type conductors based on LiGe2(PO4)3 are very promising lithium-conducting electrolytes for all-solid-state lithium-ion and lithium batteries. Al-doped LiGe2(PO4)3 solid electrolytes possessed higher conductivity (∼10-4 S/cm at room temperature) and stability versus metallic Li. In this paper, we present the structure study of Li1.5Al0.5Ge1.5(PO4)3 compound. Fast lithium-ion conductor Li1.5Al0.5Ge1.5(PO4)3 solid electrolyte have been obtained through glass crystallization at 820 °C during 8 h. Structural positions occupied by atoms have been examined by solid state nuclear magnetic resonance experiments. 6Li, 7Li, 27Al 31P NMR measurements have been performed at room temperature. © Published under licence by IOP Publishing Ltd.Russian Science Foundation, RSFThe reported study was funded by the Russian Science Foundation according to the research project № 18-73-00099.

Recombinant monovalent llama-derived antibody fragments (VHH) to rotavirus VP6 protect neonatal gnotobiotic piglets against human rotavirus-induced diarrhea

Group A Rotavirus (RVA) is the leading cause of severe diarrhea in children. The aims of the present study were to determine the neutralizing activity of VP6-specific llama-derived single domain nanoantibodies (VHH nanoAbs) against different RVA strains in vitro and to evaluate the ability of G6P[1] VP6-specific llama-derived single domain nanoantibodies (VHH) to protect against human rotavirus in gnotobiotic (Gn) piglets experimentally inoculated with virulent Wa G1P[8] rotavirus. Supplementation of the daily milk diet with 3B2 VHH clone produced using a baculovirus vector expression system (final ELISA antibody -Ab- titer of 4096; virus neutralization -VN- titer of 256) for 9 days conferred full protection against rotavirus associated diarrhea and significantly reduced virus shedding. The administration of comparable levels of porcine IgG Abs only protected 4 out of 6 of the animals from human RVA diarrhea but significantly reduced virus shedding. In contrast, G6P[1]-VP6 rotavirus-specific IgY Abs purified from eggs of hyperimmunized hens failed to protect piglets against human RVA-induced diarrhea or virus shedding when administering similar quantities of Abs. The oral administration of VHH nanoAb neither interfered with the host's isotype profiles of the Ab secreting cell responses to rotavirus, nor induced detectable host Ab responses to the treatment in serum or intestinal contents. This study shows that the oral administration of rotavirus VP6-VHH nanoAb is a broadly reactive and effective treatment against rotavirus-induced diarrhea in neonatal pigs. Our findings highlight the potential value of a broad neutralizing VP6-specific VHH nanoAb as a treatment that can complement or be used as an alternative to the current strain-specific RVA vaccines. Nanobodies could also be scaled-up to develop pediatric medication or functional food like infant milk formulas that might help treat RVA diarrhea.Fil: Vega, Celina Guadalupe.

A social portrait of the Russian trainer

The purposes of this paper are to survey Russian trainers to create a social portrait of the professional group and to identify features, which could be arranged as a foothold for transforming this group to a new level given the demands of the modern economy. This study integrates the use of quantitative and qualitative social research strategies to obtain, aggregate, and analyze data characterizing the professional group of trainers in the Russian vocational education and training (VET) system. The basic research was provided by questionnaires in all federal districts (as recognized by international law) of the Russian Federation. The quantitative poll of trainers was conducted by representative two-level sampling. A number of tables and charts provide a social portrait of the Russian trainer. The statistical data reveal the current level of trainers’ education as well as their length of service, distribution of vocations, and other significant features. The overall conclusion from these findings indicates that a typical representative of this professional group is a woman of average or slightly advanced age with a family, who has a VET or higher education, has served as a training officer for not less than 10 years, and who has either been recruited as a highly skilled worker or as a specialist. A typical representative feels the need to change something in the life and teaching of the young people that she knows. The research into trainers as a professional group was conducted first because of their uniformity, and secondly, their typicality as a pedagogical group. In many respects, the main characteristics of the social portrait are similar to characteristics of other professional groups in the Russian education system, such as secondary and post-secondary school teachers, and VET teachers. The study is based on one country. It is the first and only survey of its type in the Russian Federation. The paper provides a unique analysis of the situation with trainers in the VET system of the Russian Federation. © 2016 Kopnov et al

Dermatoscopic Pattern in Children with Microsporia and Pityriasis rosea

The present work includes a literature review and own investigations of dermatoscopic patterns of microsporia on the skin and pityriasis rosea in children. The method to investigate differential diagnosis between microsporia of the skin and the pityriasis rosea in children was the goal of the manuscript. Dermatoscopic examination of skin lesions is performed in 120 children using the manual contact dermatoscope (Heine Delta 20). In microsporia of the skin following dermatoscopic patterns were found: erythema without vessels in 56 patients (98.2%), white round spots (micro pustules compatible) at 30 examinees (52.6%), brown spots surrounded by a white-yellow halo with loss of vellus hairs were found in 50 children (87.7%), rough scales with chaotic distribution were detectable in 55 of 57 patients with microsporia (96.5%). In the following pityriasis rosea dermatoscopic signs were observed: a yellowish background at 60 children (95,2%), linear irregular vessels in 55 patients (87.3%), thin scales, located on the periphery “lace collar” in 59 of 63 surveyed (93.6%). Typical diagnostic patterns of the skin microsporia and pityriasis rosea in children were found. In the case of the microsporia of the skin, the diagnostic procedure supported the assessment of the involvement of vellus hairs and a timely prescription of systemic antifungal therapy, which shortens the duration of therapy.Die vorliegende Arbeit umfasst eine Literaturrecherche und eigene Untersuchungen der dermatoskopischen Muster der Mikrosporie an der Haut und der Pityriasis rosea bei Kindern.

Latent risks of secondary vocational school teachers’ professional activity: results of sociological research

The article presents the results of sociological research of the work of secondary school teachers who do not have psychological and pedagogical education. The analysis of the sociological research data shows that 84.1% of teachers (the re-spondents) having no psychological and pedagogical education are of working age. Among them, 24.6% of teachers belong to the age group of up to 35 years. This leads to the problems and difficulties of modernization of vocational education. The main trends of secondary vocational education development for the next five years are updating of vocational education content, implementation of the federal government standards, professional standards, modern methods and educational technologies in the system of secondary vocational education. All these tasks cannot be fulfilled without a serious pedagogical trainingВ статье приводятся результаты социологического исследования профессиональной деятельности преподавателей СПО, не имеющих профессионально-педагогического образования. Анализ данных социологического исследования показывает, что 84,1 % преподавателей (из числа опрошенных), не имеющих профессионально-педагогического образования, находятся в наиболее активном трудоспособном возрасте. Среди них 24,6 % преподавателей, входящих в возрастную категорию до 35 лет. Это приводит к проблемам и затруднениям в реализации задач модернизации среднего профессионального образования. Основными направлениями развития системы СПО в ближайшее пятилетие станут обновление содержания профессионального образования и внедрение в системе СПО ФГОС, профессиональных стандартов, современных методик и образовательных технологий, которые нельзя освоить без серьезной педагогической подготовки. Для решения поставленных профессионально-педагогических задач сегодня уже недостаточно уровня витагенного и ситуативного педагогического опыта, имеющегося у преподавател
