In order to test in orbit a wide variety of new systems and technologies and to carry out associated research, the Royal Aerospace Establishment is developing two small 50 kg satellites, designated Space Technology Research Vehicles 1a and 1b. They are scheduled to be launched into the geostationary transfer orbit by an Ariane 4 in 1993; in this orbit they will be able to investigate the effects of a very high radiation dose, atomic oxygen erosion and spacecraft charging. The paper discusses the design of the spacecraft and describes the development status as at September 1991. Details are also given of a selection of the payload experiments.

The record-breaking heatwave of 2003 also had an impact on the vegetation in Switzerland. To examine its influences seven phenological late spring and summer phases were evaluated together with six phases in the autumn from a selection of stations. 30% of the 122 chosen phenological time series in late spring and summer phases set a new record (earliest arrival). The proportion of very early arrivals is very high and the mean deviation from the norm is between 10 and 20 days. The situation was less extreme in autumn, where 20% of the 103 time series chosen set a new record. The majority of the phenological arrivals were found in the class «normal» but the class«very early» is still well represented. The mean precocity lies between five and twenty days. As far as the leaf shedding of the beech is concerned, there was even a slight delay of around six days. The evaluation serves to show that the heatwave of 2003 strongly influenced the phenological events of summer and spring.

Microbial electrochemical systems are a fast emerging technology that use microorganisms to harvest the chemical energy from bioorganic materials to produce electrical power. Due to their flexibility and the wide variety of materials that can be used as a source, these devices show promise for applications in many fields including energy, environment and sensing. Microbial electrochemical systems rely on the integration of microbial cells, bioelectrochemistry, material science and electrochemical technologies to achieve effective conversion of the chemical energy stored in organic materials into electrical power. Therefore, the interaction between microorganisms and electrodes and their operation at physiological important potentials are critical for their development. This article provides an overview of the principles and applications of microbial electrochemical systems, their development status and potential for implementation in the biosensing field. It also provides a discussion of the recent developments in the selection of electrode materials to improve electron transfer using nanomaterials along with challenges for achieving practical implementation, and examples of applications in the biosensing field.

Abstract Prolificacy is a very important trait in sheep. Romanov sheep, the well-known Russian sheep breed, are characterized by very high prolificacy; however, the genetic basis of this unique property of Romanov sheep is still unknown. It was reported that Ovine BMPR1B gene, located on the OAR6, is associated with prolificacy in several sheep breeds. The aim of our study was to identify candidate SNPs within BMPR1B gene, related to prolificacy. To achieve this goal, using NGS technology, we sequenced ovine BMPR1B gene in Romanov sheep (n = 6), which are characterized by high prolificacy (about 270 lambs per 100 ewes). The sequences of BMPR1B gene of Noire du Velay, Tan, Southdown and Australian Horned Merino sheep breeds as well as Asiatic mouflon (n = 1), which are characterized by significantly lower prolificacy (from 110 to 180 lambs per 100 ewes) were derived from publicly available sources and used for comparison. FST analysis performed in PLINK 1.9 program revealed 10 SNPs with values higher than 0.8. The majority of candidate SNPs under putative selection were localized in the region from 29,382,098 to 29,430,387 on OAR6 of Ovine reference genome (Oar_v3.1 (Ensembl release 98). Thus, we can suggest, that this region of the BMPR1B gene can be considered as the putative region, associated with high prolificacy of Romanov sheep. Additional studies will be needed to confirm the effect of identified candidate SNPs on prolificacy traits. The research results will be useful for artificial selection of sheep with higher prolific capacity, including the introduction of desired alleles in sheep populations using genome editing technologies. This work was supported by the Russian Ministry of Science and Higher Education No. 0445-2019-0024 and RFBR No. 20-516-56002.

The diagnosis of stable ischemic heart disease begins with a careful clinical examination of the patient and non-invasive testing to identify the disease. Patients with very low and very high pretest probability should not undergo various non-invasive tests. Various non-invasive tests are available to assess the presence of coronary heart disease in patients with an intermediate probability of ischemic heart disease (15–65%). The combination of anatomical with functional non-invasive tests helps improve diagnostic capabili of the disease.

Представлены результаты работы по изучению влияния филлоксероустойчивых подвоев Берландиери × Рипариа Кобер 5ББ и Берландиери × Рипариа Телеки 4Б (СО4) на агробиологические и увологические показатели крымского технического белоягодного аборигенного сорта винограда Кокур белый в условиях Алуштинской долины (филиал «Алушта» ФГУП «ПАО «Массандра»). Для проведения исследований были выбраны: участок № 361, площадью 4,49 га, на котором произрастают кусты винограда Кокур белый, привитые на подвое Берландиери × Рипариа Кобер 5 ББ (2010 год посадки, схема 3 м ×1,25 м) и участок № 391, площадью 3,06 га, на котором возделываются растения сорта Кокур белый, привитые на подвое Берландиери × Рипариа Телеки 4Б (СО4) - 2011 год посадки, схема 3 м × 1 м). На обоих участках система ведения кустов - вертикальная трехпроволочная шпалера, формировка АЗОС-1, высота штамба - 1,3 м. Показана целесообразность проведения работ по улучшению сорта Кокур белый методом клоновой селекции на сортоподвойной комбинации Кокур белый подвой Кобер 5 ББ: у растений отмечен высокий уровень коэффициента плодоношения (0,92), довольно крупные грозди (365 г), урожай с куста в среднем составил 4,74 кг/куст, очень высокая продуктивность побега по сырой массе грозди - 336,6 г/побег, большой процент выхода мякоти и сока - 91,3%. Оценка имеющихся сортоподвойных комбинаций в производственных условиях позволила провести индивидуальный отбор генотипически ценных в биолого-хозяйственном отношении форм растений.The paper reports on the findings of a study on the influence of phylloxera-resistant rootstocks ‘Berlandieri’בRiparia Kober 5BB’ and ‘Berlandieri’בRiparia Teleki 4B (СО4)’ on the agro-biological and uvological indicators of Crimean aboriginal grapevine variety used in winemaking ‘Kokur Beliy in the conditions of Alushta valley (branch of Alushta FGUP PAO Massandra). The following were selected for research: plot № 361 with an area of 4.49 hectares with bushes of ‘Kokur Beliy’ grafted on rootstock of ‘Berlandieri’ × Riparia Kobera 5 BB’ (planting year - 2010, planting scheme 3 m ×1.25 m) and plot № 391 covering 3.06 hectares with ‘Kokur Beliy’ vines grafted on ‘Berlandieri’ × ‘Riparia Teleki 4B (СО4)’ rootstock - planting year - 2011, planting scheme 3 m×1 m). On both plots, the training system used was vertical three-wire trellis, vines shaped as AZOS-1, the trunk height 1.3 m. The paper demonstrates the relevance of the work on improvement of ‘Kokur Beliy’ cultivar with the help of clonal breeding on rootstock cultivar combination ‘Kokur Beliy’ rootstock ‘Kober 5 BB’: the plants demonstrated high relative productivity (0.92), quite large bunches (365 g), yield per bush made on average 4.74 kg/bush, very high shoot productivity as per raw bunch weight 336.6 g/shoot, a large percentage of pulp and juice output - 91.3 %. Assessment of the cultivar-rootstock combinations under production conditions allowed making individual selection of genotypically valuable, from the biological and economic points of view, plants.
