DMSA-camSPECT/US fusion imaging of children’s kidneys – Proof of feasibility
Authors: Gühne Falk , Weigel Friederike , Kühnel Christian , Seifert Philipp , Freesmeyer Martin
Published: December 2019

Aim SPECT using Tc-99m-dimercaptosuccinic acid (DMSA-camSPECT) and ultrasound (US) are useful diagnostic modalities in pediatric nephrology. Former studies proved SPECT/US fusion to be a problem-solving tool for thyroid and sentinel lymph node imaging. The purpose of this study was to demonstrate the feasibility of real-time DMSA-camSPECT/US fusion in children and to evaluate the technical implementation.

Methods Subsequent to a clinical indicated DMSA-camSPECT showing a mostly normal result, 10 children received a SPECT/US fusion. The magnetic sensor-navigated equipment allows a real-time superposition of three-dimensional SPECT data to live US images according to the position of the transducer.

Results 100 % of still images and 90 % of cine-loops were sufficient to depict the kidney; at least one sufficient camSPECT/US fusion loop could be accomplished for every kidney examined. Limitations are mainly caused by standard difficulties of conventional US.

Conclusion Real-time DMSA-camSPECT/US is feasible in depiction of renal parenchyma. This newly implemented application broadens the scope of SPECT/US fusion imaging.

Bringing the policy in: a new typology of national referendums
Authors: Silagadze Nanuli , Gherghina Sergiu
Published: December 2019

Scholarship has categorized referendums predominantly along their procedural and institutional features. This paper moves beyond these formal dimensions, argues that the policy subjected to a popular vote is the missing link and proposes a complementary typology based on the policy areas. This typology fosters comparisons across countries, political systems and over time within one policy area, thus serving as a powerful analytical tool for further analyses. At the same time, the typology maps out the history of referendum use showing the chronology of salient issues in different societies. The empirical evidence draws on an original dataset of 630 nationwide referendums in Europe between 1793 and 2019.
Spin Hall effect investigated by spin Hall magnetoresistance in Pt100−xAux/CoFeB systems
Authors: Saito Yoshiaki , Tezuka Nobuki , Ikeda Shoji , Sato Hideo , Endoh Tetsuo
Published: December 2019

We studied spin Hall effect (SHE) in Pt100-xAux with various Au compositions x for Pt-Au/CoFeB systems by means of spin Hall magnetoresistance (SMR). We synthesized low resistive, flat, and highly (111)-textured Pt-Au alloy films by sputtering using low pressure Kr gas. We found that spin Hall angle (θSH), spin Hall conductivity (σSH), and spin diffusion length (λS) increase by alloying Pt with Au at certain x. The enhancement of σSH is consistent with the theoretically predicted increase in the intrinsic spin Hall conductivity, however quantitatively, there are some discrepancies in θSH and λS between our result and the experimental and theoretical results in the literatures 19 and 20. The discrepancy between our results and previous results would be related to the difference of the nanostructure in Pt-Au alloys related to the scattering from film surfaces and grain boundaries and the degree of phase separation in Pt-Au alloy systems.
Magnetic skyrmions in nanostructures of non-centrosymmetric materials
Authors: Mathur Nitish , Stolt Matthew J. , Jin Song
Published: December 2019

Magnetic skyrmions are a new form of magnetic ordering with whirlpool-like spin arrangements. These topologically protected particlelike spin textures were first discovered a decade ago in noncentrosymmetric magnetic materials. Confining magnetic skyrmions in nanostructures leads to interesting fundamental insights into skyrmion stability and could provide convenient platforms for potential practical applications of skyrmions in information storage technology. In this research update, we summarize the recent advances on studying magnetic skyrmions in nanostructures of skyrmion hosting noncentrosymmetric materials (especially the B20 materials) made via bottom-up synthesis or top-down fabrication methods. We discuss various real space imaging (such as Lorentz transmission electron microscopy or electron holography) or physical property measurement (such as magneto-transport) techniques that have been used to observe and detect these exotic magnetic domains in both nanostructure and bulk samples, which have proven to be critical to fully understanding them. We examine the importance of morphology and dimensionality of skyrmion hosting materials in stabilizing isolated magnetic skyrmions in confined geometry and their benefits for implementation in magnetic memory applications. We further highlight the need for experiments that allow the skyrmion research to move from the fundamental physics of skyrmion formation and dynamics to more applied device studies and eventual applications, such as the all-electrical writing and reading of skyrmions needed for skyrmion-based high density magnetic memory storage devices.
Supramolecular nanoarchitectonics for functional materials
Authors: Ariga Katsuhiko , Shrestha Lok Kumar
Published: December 2019

Nanoarchitectonics has been paid much attention as an emerging concept to architect functional materials from molecular and nanounits through the combination of nanotechnology-oriented strategies and supramolecular-chemistry-like methodologies. This perspective article aims to figure out important keys for materials nanoarchitectonics. In the initial part, recent trends in materials nanoarchitectonics upon supramolecular self-assembly are overviewed. The overview processes extract several key words including dynamic natures, dimensional controls, and interfacial processes according to the following sections: (i) preparation of assembled structures and conversion into nanostructured materials, (ii) dynamic structural transformation to hierarchic materials, and (iii) material preparation and functions with dynamic flows at interfacial media. Not limited to the material production, dynamic processes at the interface can be also connected with forefront functions such as tuning of molecular receptors and mechanical controls. This perspective article can conclude that fabrication of functional materials and controls of nanosystems would be well-considered on the basis of these three key terms.
Inhibiting extracellular vesicles formation and release: a review of EV inhibitors
Authors: Catalano Mariadelva , O'Driscoll Lorraine
Published: December 2019

It is now becoming well established that vesicles are released from a broad range of cell types and are involved in cell‐to‐cell communication, both in physiological and pathological conditions. Once outside the cell, these vesicles are termed extracellular vesicles (EVs). The cellular origin (cell type), subcellular origin (through the endosomal pathway or pinched from the cell membrane) and content (what proteins, glycoproteins, lipids, nucleic acids, metabolites) are transported by the EVs, and their size, all seem to be contributing factors to their overall heterogeneity. Efforts are being invested into attempting to block the release of subpopulations of EVs or, indeed, all EVs. Some such studies are focussed on investigating EV inhibitors as research tools; others are interested in the longerterm potential of using such inhibitors in pathological conditions such as cancer. This review, intended to be of relevance to both researchers already well established in the EV field and newcomers to this field, provides an outline of the compounds that have been most extensively studied for this purpose, their proposed mechanisms of actions and the findings of these studies.
The domestic politics of international climate commitments: which factors explain cross-country variation in NDC ambition?
Authors: Tørstad Vegard , Sælen Håkon , Bøyum Live Standal
Published: December 2019

Under the Paris Agreement, parties self-determine their mitigation ambition level by submitting Nationally Determined Contributions (NDCs). Extant assessments find that the collective ambition of current pledges is not line with the Agreement’s goals and that individual ambition varies greatly across countries, but there have not been attempts at explaining this variation. This paper identifies several potential drivers of national climate ambition, and tests whether these can account for differences in the ambition level of countries’ mitigation targets under the Paris Agreement. After outlining theorized relationships between a set of domestic political characteristics and climate policy ambition, regression analysis is used to assess the effects of different potential drivers across a dataset of 170 countries. We find that a country’s level of democracy and vulnerability to climate change have positive effects on NDC ambition, while coal rent and GDP have negative effects. Our findings suggest that these objective factors are more important than subjective factors, while the most influential subjective factor is the cosmopolitanism-nativism value dimension.

Published: December 2019

The study is aimed at determining the etiopathogenesis of reproductive ability disorder among high-producing cows. For this purpose, a group of cows amounting 37 heads was formed following the principle of analogous pairs. The cows were inseminated during the first estrum after calving, and then their blood was drawn using Monovette system taking into account sterility terms. In the drying off period, the blood was drawn 1-4 days before calving and during the first day after calving. Totally 253 blood samples were tested. Proceeding from the results, cows were divided into two groups. The first group included 20 cows impregnated after the first insemination; the second group included 17 not impregnated cows. Later the blood was drawn providing for the parturition process and postpartum period. Blood values were investigated by commonly accepted methods using certified equipment. The study showed that cows during the early gestation have lipid metabolism, lipid peroxidation and antioxidant system state significantly differing from those among non-pregnant cows. During the gestation, cows have the level and class of general lipids reducing, as well as the accumulation of lipid peroxidation products. Cattles with retained placenta have low lipid metabolism and higher level of peroxidation within interlactation period. After the calving, this difference tends to widen. The obtained data can be used for elaboration of measures preventing post-parturient complications by applying agents with antioxidant properties.

Authors: Nitsievskaya Kseniya , Motovilov Oleg , Sherbinin Vyacheslav
Published: December 2019

The article presents the semi-finished product recipe for bakery products, the feature of which is the introduction of white flax seeds and wheat grains in their native form. The technology provides for the processing of plant materials in the form of whole seeds (grains) to increase nutritional value by improving the fatty-acid and amino-acid composition, as well as enriching the finished product with plant fiber and biologically active substances of plant origin. Using the principle of hydromechanical dispersion as the basis for technological processing of raw materials will allow preserving the native properties of raw materials and prolonging the expiration date of bakery products obtained on the basis of the semi-finished product, and reducing the process of moisture loss during storage. A mechanical-acoustic apparatus is used as technical and hardware equipment, which allows reducing microbial contamination and improving the safety of the semi-finished product during further storage and baking of finished bakery products. Statistical processing of organoleptic assessment data is presented taking into account weighting factors in comparison with a control sample. The energy value of the experimental samples of bakery products was calculated, indicating an increase in the caloric value of the samples with an increase in the content of white flax seeds in the recipe. A methodology for constructing a cause and effect diagram for the example of the production quality analysis of bakery products is considered. The root causes of possible risks of quality deterioration in the production of bakery products are identified.

Published: December 2019

The search for new ways to optimize the adaptive capabilities of service dogs is a prerequisite for increasing the viability of animals and increasing their longevity. Dihydroquercetin neutralizes the increased level of free radicals toxic to the body, protecting cell membranes from destruction, and reduces the harmful effects of oxidative stress. The use of dihydroquercetin contributed to increased providing cells with oxygen, stimulated anabolic processes and increased the antioxidant defense of the body. The amount of red blood cells in the blood of service dogs increased by 11.5-19.1% (p<0.01) when using dihydroquercetin, hemoglobin increased by 5.7-9.4% (p<0.05), total protein by 21-32% (p<0.01), albumin by 30-31% (p<0.001), compared with similar data at the beginning of the experiment. The antioxidant properties of dihydroquercetin contributed to the reduction of malondialdehyde by 23.9% (p <0.05); reduction of diene conjugates by 26%; and an increase in catalase activity by 36% compared to the data on the first day of the experiment. The use of dihydroquercetin optimizes the adaptive capabilities of service dogs and can be used to increase the vitality and longevity of animals.

Published: December 2019

The study is aimed at reducing the negative impact of open ground on plants during the growth season and during adverse extreme impacts, with the maximum reduction in response time to changes in external conditions. The developed screens do not limit the conditions of natural pollination and access to plants for irrigation, machining and harvesting, extend the vegetation period of plants, and contribute to increased yield. The proposed solutions are based on the dualism principle stating that the cultivated plant is both in open ground and under the protection of screens. The objectives of the study: to reveal the impact of design parameters of protective screens on the temperature regime in the inter-screen space; to determine the possibility of monitoring the plant moisture supply under the screens using the method of calculating the moisture stress index in real time; to assess the effectiveness of protecting the plants with screens from the effects of negative factors caused by open ground. The reason for the temperature change in the presence of insolation is the effect of interlocking of vertical convective air currents that form in the space between the screens. By changing the opening parameters of the face ends, it is possible to increase the air temperature in the plant zone or to protect them from overheating. The moisture stress index can be used to quickly monitor the water regime of plants. Protective screens contribute to the accumulation of active temperatures, extending the growing season, reducing the risks of negative impact caused by open ground factors, and increasing the productivity compared to open ground conditions.

Increasing power supply efficiency of livestock complexes at small farms using renewable energy sources
Authors: Rudenko Nikolay , Ershov Valery , Trints Dmitry
Published: December 2019

The paper provides technical recommendations for designing power supply systems for livestock complexes of small farms based on renewable sources of electric energy. Resource analysis of solar and wind energy on the Russian Federation territory shows that the use of the hybrid solar-wind power plants is most appropriate. In the case, it is advisable to use batteries and diesel generators to ensure reliable and uninterrupted power supply. Herein is offered a version of making up a structural diagram of power supply system for a small farm with combined power supply from centralized power grids and renewable energy sources. It is shown that the use of such a system can significantly save due to the power not consumed from the grid, and also allows selling excess energy to the power system. Herein is offered a version of building up a structural diagram of an autonomous power supply system based on a hybrid solar-wind power plant and a diesel generator for those regions, where there is no distributive electrical network. A design of a vortex wind power installation has been developed for practical use as part of the considered options for power supply schemes, which allows using small winds and low-potential thermal upward flows, reducing low-frequency vibration and noise, placing it on the top of industrial buildings with ease of installation, maintenance and repair.

Published: December 2019

In the production of starch products from corn grain, a number of valuable byproducts are obtained, the bulk of which are pulp, corn extract, crushed corn grain and oilcake. By-products of starch production in the feeding rations of farm animals are mainly used as separate components, which reduces the effectiveness of their use. It is most advisable to feed them in the form of a dry mixture as concentrated corn feed, which is proposed to be cooked in a spiral mixer. The design and technological scheme of the mixer should include a framework with a spiral installed in it, one end of which is fixed to the eccentric of the leading pin and the other to the driven pin of the feed change mechanism with the possibility of horizontal movement. To justify the design and technological parameters and rational operating modes of the mixer, theoretical, laboratory and production tests were performed, their results are presented. Based on the data obtained, the parameters and operating modes of the spiral mixer are substantiated. As a result of production tests, the developed mixer, used in the processing lines for the preparation of crumbly and granular feed, confirmed its operability
RETRACTED: Principles of improving the smoothness of the working mechanism in forging and stamping machines
Authors: Kobzev Kirill , Chukarin Alexsandr
Published: December 2019

The analysis of safety clutches shows that, despite the high rates of scientific and technical progress in the field of mechanical engineering, the development of safety clutch designs is noticeably lagging behind, and their technical and operational characteristics in general do not fully comply with modern requirements for the protection of machine drives. Friction clutches have a high response accuracy, but at present they do not provide the necessary level of protection against overloads. For a certain period of time, these performance characteristics met the necessary requirements for accuracy of operation. However, due to the steady increase in the technical characteristics of machines and mechanisms at present, some technological equipment requires the implementation of technological processes to preserve existing power factors with minimal (up to 7 … 10%) deviation of the nominal values. Such equipment may include, for example, forging and stamping equipment. To ensure a high degree of constancy of the working forces and moments in the drives of the specified equipment, the use of safety couplings with a significantly higher accuracy of operation within the above limits is required.

Authors: Novikova Elena , Sayfutdinov Rinat
Published: December 2019

The article proposes a method for measuring the sparking voltage in DC electric machines based on the transient functions of these machines connected to bipolar brushes. Knowing the resulting response of the system to an impact in the form of a series of pulses obtained experimentally, it is possible to determine the response of the system to an arbitrary input action from a real spark in the sliding electrical contact of an electric machine. Using real transitional parameters of the anchor circuit of an electric machine will eliminate the systematic error of the method for estimating the level of switching sparking using a signal with bipolar brushes of this machine.
Construction of stochastic transport models with a constant function
Authors: Karachanskaya Elena , Tagirova Tatiana
Published: December 2019

The paper considers two transport models described using stochastic differential equations system. The investigation is based on a constant function of motion. The approach allows building stochastic dynamical model using a well-known deterministic model and its constant function. The construction algorithm is realized as a software, and it allows choosing a set of functions for simulation. Moreover, it is possible to construct both a system of stochastc differential equations and a system of deterministic ones. The article represents a stochastic model for a vehicle movement and an idea for an itinerant aircraft stochastic model. Transit from a deterministic model to stochastic one is carried out by completing of three addition terms. The first term is a continuous random influence. The second one describes strong random jumps. The third item is an addition component for a drift coefficient. It was shown that choice of additional functions allows building a system of equations with such coefficients that the resolution of this system meets reasonable restrictions. Examples of numerical solutions of the equations constructed confirm the conservation of the value of dynamic invariant under any solution of stochastic differential equations system.

Russian transporters receive an opportunity to increase carriage volumes and seek an additional income, Russian government, in this case, may receive additional tax payments into the budget. In order to increase the number of freight trains with the usage of railroad transit services on 1520mm gauge it is necessary to improve transport and logistics infrastructure. New transport corridor for delivering container freights into Europe through Kaliningrad Region and the use of railroad route through Mongolia are considered to be perspective solutions. Based on the analysis results it was stated that there is a possibility to redeploy existing and perspective container transit volumes on the China-Europe lane through border crossing points Dostyk, Zabaikalsk and Zamyn-Uud. Goods for e-commerce has the greatest importance in the structure of transit freights. The switch of international flow of goods from airplane to rail transportation for the purpose of e-commerce is also another opportunity to increase the volume of transit traffic through Russian territory. It will give benefits as for clients, as for Russian Railroad company. In order to implement these opportunities, it is necessary to solve a set of legal, organizational and technical tasks.

The paper presents the results of studying the efficiency of use at the railway loop of the technology of handling heavy multiple-unit trains made up with several heavy train units, the mass of each of which is higher than the scheduled one. This technology is advisable to apply in conditions where the mass of a heavy multiple unit train consisting of m heavy train units exceeds the mass of a scheduled train by more than n times. The paper presents the main advantages and disadvantages of the technology of making-up and handling of heavy multiple-unit trains, as well as the classification of the main cost indicators, which should be taken into account when determining the economic efficiency of the technology. The formulas for calculating the cost, return and investment are presented. Assessing the economic efficiency of applying the technology for making-up and driving heavy multiple-unit freight trains can be done using indicators – operating profit, comparative economic effect and a simple payback period of investments. In addition to the specified set of indicators, economic criteria can be calculated taking into account the influence of the time factor: net present value, profitability index and discounted payback period of the project. Using the presented methodology will allow evaluating economic effect of application of the technology of making-up and handling of heavy-duty multiple-unit trains as that responding the growing freight traffic.

Published: December 2019

In the modern practice of transporting goods in cities, the use of motor vehicles on an hourly basis has become widespread, although it is known that their use is much less efficient. The purpose of this paper is to increase the efficiency of cargo transportation in cities by motor vehicles on an hourly payment basis by developing methods for operational planning of cargo transportation in cities by motor vehicles used on an hourly payment basis and practical recommendations for its use. The developed methodology considers the existing practice of cargo transportation. By default, it is assumed that a client who rents a car on an hourly basis has the competence to organize cargo transportation in cities. In an order application, the client indicates a car, body type and order time. Thus, it seems that the decision of the client when ordering always contributes to the positive satisfaction of his needs. However, the results of the study suggest that the use of cars on an hourly payment basis for the transportation of building or commercial goods at different distances in urban environments gives different results. Applying the results of this study allows assessing customer satisfaction and prevent undesirable outcomes prior to experience.

In today’s diverse world, one of the most urgent tasks is environmental protection, rational use and reproduction of natural resources, conservation of biological diversity. The problem of clean water is one of the most important places in the solution of this problem because surface waters are the most sensitive natural environment link. Without careful monitoring of the state indicated by the latter, it is impossible to prevent the occurrence of adverse environmental situations, maintain the health of the nation and ensure the quality of life. Based on the results of the analysis of indicators of the quality of the water source, the required volumes of water for the consumer and the requirements of the consumer for the produced water, a decision is made on the technology for purifying the required water. Special climatic conditions (sharply continental climate, high summer temperatures, low water levels, etc.) negatively affect the quality indicators of the water source. The article presents the results of a study of surface water by microbiological indicators and phytoplankton. Water was investigated in the area of the channel-type surface water intake structure located in the Astrakhan region on the Volga. It is revealed that the river belongs to the category of dirty. Moreover, there is a positive trend in the development of this process. Applied water treatment technologies are not able to fulfill the tasks to ensure a safe drinking regime. It is known that chlorination of water during water treatment does not affect the removal of metabolites secreted by massively developing species of cyanobacteria (blue-green algae). The recommendations for improving water treatment facilities are made.

Sponge is one of the benthic organisms that could be found in seagrass ecosystem. Sponge is also could harbor various organisms within its tissue, as a biogenic habitat for those associative organisms. This interaction could benefit from enhancing marine biodiversity in the seagrass ecosystem. Aims of this research were study the abundance of associative mesofauna and its correlation with the sponges antibacterial activity. Sponges samples were preserved in 70% ethyl alcohol (0.5-1 cm3 thickness) and observed under stereomicroscope, to find the associative mesofauna. Meanwhile fresh tissue samples were tested against several pathogenic bacteria in antibacterial assay. Associative mesofauna that was found in 14 of 23 seagrass sponge species, belong to Ophiuridae, Mollusca, Gastropoda, Arthropoda, Polychaeta, and Oligochaeta groups. Mollusca and Polychaeta were highly correlated with most of the sponge species (8 of 14), based on statistical correspondence analysis (CA). Antibacterial assay on sponge tissue showed that only 6 of 14 sponge species has activity against several pathogenic bacteria. Statistical analysis (CA) showed that Mollusca and Polychaeta also have high correlation with the antibacterial activity. This suspected that sponges defense mechanism strategy against pathogenic bacterial infections, could influence the preference of associative mesofauna inhabiting seagrass sponges.
