Modelling the early evolution of extracellular matrix from modern Ctenophores and Sponges

Published: August 2019

Abstract
Animals (metazoans) include some of the most complex living organisms on Earth, with regard to their multicellularity, numbers of differentiated cell types, and lifecycles. The metazoan extracellular matrix (ECM) is well-known to have major roles in the development of tissues during embryogenesis and in maintaining homoeostasis throughout life, yet insight into the ECM proteins which may have contributed to the transition from unicellular eukaryotes to multicellular animals remains sparse. Recent phylogenetic studies place either ctenophores or poriferans as the closest modern relatives of the earliest emerging metazoans. Here, we review the literature and representative genomic and transcriptomic databases for evidence of ECM and ECM-affiliated components known to be conserved in bilaterians, that are also present in ctenophores and/or poriferans. Whereas an extensive set of related proteins are identifiable in poriferans, there is a strikingly lack of conservation in ctenophores. From this perspective, much remains to be learnt about the composition of ctenophore mesoglea. The principal ECM-related proteins conserved between ctenophores, poriferans, and bilaterians include collagen IV, laminin-like proteins, thrombospondin superfamily members, integrins, membrane-associated proteoglycans, and tissue transglutaminase. These are candidates for a putative ancestral ECM that may have contributed to the emergence of the metazoans.
Data‐based differential matched‐mode source depth estimation for a moving source

Published: August 2019

For locating a target moving in a more general track relative to the single receiver and at an ultra‐low frequency (<100 Hz) effectively, a differential matched‐mode method is proposed to estimate the depth of a moving source. It relies on the Hankel transform fast Fourier transform (FFT) to estimate the modal wavenumber difference spectrum for extracting source depth information. For the real data, the received signal as a function of the range is first processed by FFT per block to obtain the pressure field per range. Then these pressure fields are steered and beamformed according to the synthetic aperture created by the source motion to yield the modal wavenumber difference spectrum. A normalised source‐depth ambiguity function configured using these spectral peaks is applied to estimate the source depth with knowledge of the mode depth functions or nominal modal functions. Numerical simulation and experimental data all have tested this method with reasonable success especially when the source travels in a non‐radial direction relative to the single receiver.
Numerical analysis of high‐voltage RESURF AlGaN/GaN high‐electron‐mobility transistor with graded doping buffer and slant back electrode

Published: August 2019

A reduced surface field (RESURF) AlGaN/GaN high‐electron‐mobility transistor (HEMT) with graded doping buffer (GDB) and slant back electrode (SBE) is proposed. In the GDB, the p‐dopant density increases linearly both from top to bottom and right to left. The concentrated negative space charges in the lower‐left corner of GDB attract the electric field lines from the channel and barrier towards the gate under OFF‐state, which flats the electric field and enhances the breakdown voltage (Vbr). Additionally, the low p‐dopant density near the top of GDB achieves the device with low ON‐state resistance (RON). The SBE flats the electric field along the channel above it and introduces a peak electric field near its edge. Simulation results show a Vbr of 2150 V and RON of 7.05 Ωmm for the proposed device, compared with 1701 V and 7.73 Ωmm for the conventional back electrode RESURF HEMT (BE‐RESURF HEMT) with the same gate ‐drain spacing. Moreover, due to the reduced depletion of 2DEG from the GDB, the proposed device shows slight increases in fT and fmax (8.76 and 14.80 GHz), comparing with the conventional BE‐RESURF HEMT (8.24 and 13.84 GHz).

Authors: van Gemert Theresa , Patricia Zaharia Oana , Roden Michael , Müssig Karsten 
Published: August 2019

ZusammenfassungDer Versuch einer neuen Diabetesklassifikation, welche neben den klassischen Merkmalen auch den Krankheitsverlauf und das Risiko für die Entwicklung von Folgeerkrankungen miteinbezieht, ermöglicht möglicherweise eine differenzierte Einteilung der Erkrankung. Dies könnte dazu beitragen, Behandlungen zu individualisieren und Personen mit einem erhöhten Risiko für Komplikationen bereits bei Beginn der Diagnose zu identifizieren, hin zu einer stratifizierten, zielgerichteten Therapie. Inwieweit sich die Ergebnisse hinsichtlich der 5 Diabetestypen auf andere Populationen übertragen lassen, bleibt jedoch zu überprüfen.
Land deals, and how not all states react the same: Zambia and the Chinese request
Authors: Widengård Marie 
Published: August 2019

ABSTRACT
The global land rush has drawn new attention to the African state. Governments have generally been accused of brokering deals that are assumed to negatively affect local people. This framing contributes to an image that all states react in the same way, ignoring that states and customary rulers still covet control over land. By drawing on a Chinese land request for 2 million hectares in Zambia, the article argues that processes of land acquisition are deeply influenced by the shifting politics and policies within the respective country, specifically since a change of government changed the dynamics of the deal.

Published: August 2019

AbstractThe vehicle detection in the aerial images is widely used in many applications. Comparing with the object detection in the ground view images, vehicle detection in the aerial images remains a challenging problem due to the small size of vehicles, monotone appearance and complex background. In this paper, we propose the solution of this issue using the convolutional neural networks. We further introduce the large-scale vehicle detection dataset with ground truth annotations for all the vehicles in the scene that considers the scene complexity due to the environmental conditions. We show the performance of the trained model with other popular neural work architectures.

Abstract
In field experiment in conditions of the Krasnoyarsk forest-steppe, the influence of the microbiological fertilizer Azofit on the properties of chernozem and the productivity of rapeseed variety Nadezhny 92, cultivated for oilseeds, was estimated. It was shown that the treatment of rapeseed using the fertilizer with subsequent foliar treatments of vegetative plants or the use of the preparation only for vegetative plants formed a normal composition and good structure of the 0-20 cm soil layer. The use of the preparation contributed to an increase in the concentration of hard hydrolysable, easy hydrolysable and ammonium nitrogen in the soil. The maximum productivity of spring rapeseeds was formed on the variant using Azofit as a protectant in its pure form with subsequent foliar treatments of the crops (2.6 t/ha).
Empathy, emotional intelligence and decision-making among managers of agro-industrial complex. The role of tolerance for uncertainty in decision-making
Authors: Vyatkin A V , Fomina L V , Shmeleva Zh N 
Published: August 2019

Abstract
The article is devoted to the study of the peculiarities in decision-making by the managers of the agro-industrial complex enterprises. Managing agrarian enterprises is connected with the necessity of considering multiple factors and risks. Therefore, the decision-making under uncertainty and risk is often stressful. Recently, the study of the role of the emotional intelligence and tolerance for uncertainty in decision-making has become relevant and indispensable. The authors conducted the research using four techniques in two groups – managers and students of universities studying on programs involving the future management of people. The positive correlation between emotional intelligence measured by the MSCEIT test and the subjects’ age was established. A higher ability to emotional self-control according to the EmIn questionnaire and emotional intelligence according to the MSCEIT test among managers were revealed. Iowa Gambling Test showed significant differences in the preference for the winning decks both by gender (higher for men) and in groups – the students showed a lower degree of self-control, but a greater propensity for risk. People who seek certainty and clarity perceive their loss very unambiguously and try to avoid the risk of such an outcome in the future. Thus, the ability to understand and regulate emotions is important in the choice of solutions; therefore, emotional intelligence plays an important role in decision-making.

Abstract
The global trends in the development of photovoltaic power stations (PPS) and their application are actively fighting for a place in the sun. On January 20, 2009, Vladimir Putin (at that time the chairman of the government) signed a decree approving the main directions of state policy in the development of renewable energy sources (RES) until 2024, and on May 13, 2019, by decree no. 216 “On the approval of the energy security of the Russian Federation” signed the Doctrine of the energy security of the Russian Federation. In this regard, the need to find the optimal operating modes of PPS has become acute, which is an environmentally friendly way to generate electricity. New designs and methods of using systems are being developed to study and determine the optimal operating modes of PPS. The work justified the design parameters and experimentally investigated the characteristics and operating modes of PPS, determined the effect of the spectral composition of radiation on the amount of generated energy. The study was conducted using graph-analytical processing of the results of practical PPS tests characteristics by simulating outlook surfaces using the biharmonic interpolation method in the Curve Fitting Toolbox application of the MATLAB program.

Published: August 2019

Abstract
Every organism is constantly exposed to biotic and abiotic environmental factors. Geological objects (soil, minerals, water, etc.) and factors play a great role in the development of a huge number of animal diseases. The diseases are endemics, for instance endemic osteodystrophy, enzootic ataxia in sheep, boric enteritis in sheep, white muscle disease and deficiency in microelements). As a result, Veterinary Geology as a new branch of veterinary medicine is being formed. Veterinary Geology studies the influence of natural and anthropogenic geological objects and processes on animal health and quality of animal products and use of minerals for treatment of animal’s diseases of different etiology. Study of the epizootic situation and the role of geological objects and processes in the animal health allow to develop successful preventive and control measures. The overview presents the areas of application, directions and prospects for the development of veterinary geology in modern conditions. The importance of application of geoinformational systems (GIS) as an optimal tool for assessing, analyzing and managing risks in this branch of knowledge is shown.

Authors: Platonov V V , Fedorov T 
Published: August 2019

Abstract
The article presents the method of the feasibility study of various methods of regulation on pumping installations of agricultural objects. It was found that the best results are observed in electric drives with frequency converters and valve cascade: here the total losses Qmin
mode are only about 10% of the base value, which is explained by minimal losses in pipelines. There is no need to use valves at all. It is shown that with parametric control of the speed of an asynchronous electric drive with a phase-rotor, the loss in hydraulic elements (pump and network) has the same value as with frequency control (about 10% of the base value), but slip losses increase by 12%

It is shown that an increase in reliability of semiconductor converters can be achieved increasing the power reserve. At the same time, if the economic indicator is chosen as an optimization criterion, the coefficient of failure-free operation reaches no more than 0.8. In the event that resulting coefficient of failure-free operation is allowed according to operating conditions, selected criterion can be successfully applied at design stage of semiconductor converters.
Improving the accuracy of electric mechanisms for the manufacture of blanks of agricultural objects
Authors: Zagoskin Y S , Tsirkunenko A T 
Published: August 2019

Abstract
The principles of increasing the precision characteristics of an agricultural electric drive are presented in this article. There are achieved by analyzing the requirements for the electric drive by the operating body. The scientific work has a relationship between the parameters of the quality of rolling the blanks for agricultural facilities and the precision parameters of the electric drive in terms of overshoot parameters and absolute positioning accuracy. It is shown that this dependence is non-linear in the position electric drive and depends more on the size of the overshoot and a significantly smaller ratio from absolute accuracy. The permissible overshoot value depends on the absolute accuracy and has range from 5 to 10%. The largest value of the overshoot is achieved with absolute positioning accuracy with an error not exceeding 2%. The obtained values of the control parameters can be successfully applied in the design of the position agricultural electric drive. So, if you provide sufficient positioning accuracy with an error not exceeding 2%, which is achieved by the use of position sensors with a resolution of at least 10 000 pulses per revolution, the modeling electric drive in the position loop can be adjusted with an allowable overshoot of 10%, and therefore, increased system performance while maintaining quality control indicators.

Published: August 2019

Abstract
Searching for new ecologically and economically efficient sources of chitin is of great interest in the field of biotechnology. Nowadays, the topic is growing fast, and many scientists, researchers, primarily the representatives of the Russian Chitin Society, study and search for new sources of chitin not only from large crustaceans, molluscs, and crabs, but also from insects and small crustaceans. Domesticated and liable to breeding representatives of invertebrate animals, particularly large American Black Soldier Fly (Hermetia illucens L.) can be new and promising raw material source. The Fly is a promising object of research because it contains a chitinous external skeleton. During the studies at the Biology, Ecology and Biotechnology Department of NARFU named after M. V. Lomonosov, there were determined a sufficiently high percentage chitin yield from dead flies equal to 21.3% (1281.2 g per year per 1 m3 of a cage), almost complete absence of residual protein (C = 0.98 µg/ml) and high adsorption ability (X = 156.6 mg/g) of the extracted polysaccharide. Studied qualitative characteristics enable to consider the product as environmentally and economically cost-effective sorbent with the possibility of application in many areas of biotechnology, environmental and industrial fields of production.

Published: August 2019

Abstract
Reactions of free radicals’ formation are integral parts of many metabolic processes in the body, but in a number of states under the influence of external and internal factors there occurs intensification of these reactions accompanied by excessive generation of phagocytizing blood cells activity (PBCA), therefore the study of the antioxidant activity of biological fluids is of clinical (diagnostic, predictive) value. The component analysis of the blood chemiluminescent kinetics of Bous Taurus of different age and sex groups was carried out. The functional activity of venous unfractionated blood cells taken from the jugular vein was evaluated by the Tono-Oke method using the “Chemiluminometer CL-3604” hardware-software complex. The analysis of the chemiluminescent kinetics of PBCA generation and the state of the organism was evaluated by the method of Magrisso M.Y. A component analysis of the blood chemiluminescent kinetics of animals of different sex, age and physiological state revealed a number of specific characteristics and pointed out the relationship between some parameters that can complete the picture of the antioxidant potential possibilities.

Abstract
This paper reports the effect of modified nutrient media on biotechnologically growing rootstock plants (Gizella – 5 and VSL – 2) at the stages of introduction and grafting. Murashige and Skoog medium was modified by adding 25 mg/l Chelate-Fe and 500 mg/l of Ca(NO)3 to the basic nutrient at the stage of introduction of the plant. At the grafting stage 0.1 mg of 6-Benzylaminopurine (6-BAP) was added to Murashige and Skoog, where the effect of regeneration was 2 times higher than in experimental control. The results obtained prove that modified Murashige and Skoog medium is to be the best nutrient media for root-plant introduction and regeneration processes in Vitro followed by Chelate-Fe, Ca(NO)3 and 6-BAP respectively.
