Authors: Feitosa Jamille A , Fernandes Corina A , Casseb Raphael F , Castellano Gabriela 
Published: December 2021

Abstract

Background. The use of virtual reality (VR) as a rehabilitation tool has been shown to induce motor and cognitive improvements in different populations. Functional magnetic resonance imaging (fMRI) has been used to investigate neuroplasticity resulting from these treatments. We hypothesize that VR rehabilitation induces functional improvement and brain changes that can be detected by fMRI. Objective. To systematically review the effects of VR intervention on the cortical reorganization measured by fMRI and associated with functional improvement. Approach. We performed a systematic review of studies published between 2005 and 2021. Papers were retrieved from six databases using the following keywords: ‘motor rehabilitation’, ‘fMRI’ and ‘virtual reality’. Case studies, pre-post studies, cross-sectional studies, and randomized controlled trials published were included. Manuscripts were assessed by The National Institutes of Health study quality assessment tools to determine their quality. Main results. Twenty-three articles met our eligibility criteria: 18 about VR rehabilitation in stroke and five on other clinical conditions (older adults, cerebral palsy, and Parkinson’s disease). Changes in neural patterns of activation and reorganization were revealed in both the ipsilesional and the contralesional hemispheres. Results were located mainly in the primary motor cortex, sensorimotor cortex and supplementary motor area in post-stroke patients in the acute, subacute, and chronic rehabilitation phases, and were associated with functional improvement after VR intervention. Similar effects were observed in older adults and in patients with other neurological diseases with improved performance. Significance. Most stroke-related studies showed either restoration to normal or increase of activation patterns or relateralization at/to the ipsilesional hemisphere, with some also reporting a decrease in activity or extent of activation after VR therapy. In general, VR intervention demonstrated evidence of efficacy both in neurological rehabilitation and in performance improvement of older adults, accompanied by fMRI evidence of brain reorganization.
Anomalous tungsten transport driven by ion temperature gradient turbulence
Authors: Xu Shaokang , Maeyama S. , Watanabe T.-H. 
Published: December 2021

Abstract
The present study reveals that the anomalous tungsten particle transport based on the nonlinear gyrokinetic simulations shares some similarities with that of the linear gyrokinetic study, meanwhile there exists some significant differences. In particular, nonlinear excitation of the linearly stable modes plays a non-negligible role in the anomalous tungsten particle transport. The highlighted results are the downshift of the critical density gradient for zero tungsten particle transport and the modification of the poloidal profile of the outward tungsten particle transport, which are both related to the small scale turbulent fluctuations. The former one is due to the outward particle convection produced by the linearly stable modes. The later one is brought by both the linearly stable modes and the large-scale eddies with finite ballooning angle, which flatten the poloidal profile of the particle diffusion and further shift the peak positions of the strongest outward particle transport to the high poloidal angle regions.
X-ray characterization of BUSARD chip: A HV-SOI monolithic particle detector with pixel sensors under the buried oxide
Authors: Alcalde Bessia F. , Lipovetzky J. , Perić I. 
Published: December 2021

Abstract
This work presents the design of BUSARD, an application
specific integrated circuit (ASIC) for the detection of ionizing
particles. The ASIC is a monolithic active pixel sensor which has
been fabricated in a High-Voltage Silicon-On-Insulator (HV-SOI)
process that allows the fabrication of a buried N+ diffusion below
the Buried OXide (BOX) as a standard processing step. The first
version of the chip, BUSARD-A, takes advantage of this buried
diffusion as an ionizing particle sensor. It includes a small array
of 13×13 pixels, with a pitch of 80 μm, and each pixel
has one buried diffusion with a charge amplifier, discriminator with
offset tuning and digital processing. The detector has several
operation modes including particle counting and Time-over-Threshold
(ToT). An initial X-ray characterization of the detector was carried
out, obtaining several pulse height and ToT spectra, which then were
used to perform the energy calibration of the device. The Molybdenum
𝐊α emission was measured with a standard
deviation of 127 e- of ENC by using the analog pulse output,
and with 276 e- of ENC by using the ToT digital output. The
resolution in ToT mode is dominated by the pixel-to-pixel
variation.

Abstract
Scintillation detector is widely used for the particle detection in the field of particle physics.
Particle detectors containing fluorine-19 (19F) are known to have advantages for Weakly Interacting Massive Particles (WIMPs) dark matter search, especially for spin-dependent interactions with WIMPs due to its spin structure.
In this study, the scintillation properties of carbontetrafluoride (CF4) gas at low temperature were evaluated because its temperature dependence of light yield has not been measured.
We evaluated the light yield by cooling the gas from room temperature (300 K) to 263 K.
As a result, the light yield of CF4 was found to increase by (41.0 ± 4.0stat. ± 6.6syst.)% and the energy resolution was also found to improve at low temperature.

Abstract
The study is devoted to the microelement composition of organs and tissues of chum salmon (Oncorhynchus keta), which came for spawning in September 2018 in the r. Lovetskaya on the southwestern coast of Sakhalin. Samples of organs and tissues of fish, prepared in Sakhalin, were frozen and delivered to Vladivostok for chemical analysis. Trace elements were determined from acid mineralizates by atomic absorption on a Shimadzu AA 6800. It was found that the content of microelements indicating anthropogenic impact on the environment (Zn, Cu and Ni) in the Sea of Japan chum was significantly higher than the content of those in the Okhotsk Sea fish. So, for example, the amount of zinc in the muscles of the Sea of Japan chum salmon was 2.5 times higher than in those of the Sea of Okhotsk fish. In the liver, the effect was even greater - the difference between the content of this element in the Sea of Japan and the Sea of Okhotsk reached 19 times. At the same time, in the organs and tissues of the Okhotsk chum salmon, which crossed the impact geochemical zone in the Kuril-Kamchatka region at least twice during its life cycle, the content of lead and cadmium, witnesses of underwater and surface volcanism in the Kuril straits, prevailed. The content of lead in the muscles of chum salmon from r. Raidovaya was 4 times more than in the muscles of chum salmon from the river. Lovetskaya; in the liver, the difference was 5 times.

Authors: Ya Prakhova T , Turina E L 
Published: December 2021

Abstract
The aim of the research is to study the effect of different backgrounds of mineral nutrition on the yield and quality of oilseeds of winter false flax in different regions of cultivation. The research was conducted in two contrasting regions: the forest-steppe of the Middle Volga region (Penza Research Institute of Agriculture) and the Central steppe zone of Crimea (Crimean Research Institute of Agriculture) in 2018-2020. The object of the research was the winter false flax varietal Baron. In the experiment, the effect of nitrogen fertilizer fertilization on the productivity of winter false flax at a dose of 0 to 60 kg of active substance per hectare with a step of 15 kg has been studied. Ammonium nitrate was used as nitrogen fertilizer. In the experiments of Penza Research Institute of Agriculture, the yield increase with nitrogen fertilizer was 0.07-0.19 t/ha. The highest yield of winter false flax was obtained in the variant with the introduction of nitrogen at a dose of N30, which was 1.61 t/ha, which significantly (0.19 t/ha) exceeded the variant without fertilizers. In the conditions of the Crimea, the yield of winter false flax in the average three years was not high and ranged from 0.95-1.16 t/ha. Fertilizing false flax with nitrogen at a dose of N30 led to an increase in yield by 0.21 t/ha, the productivity of the crop was 1.16 t/ha. Nitrogen fertilizer fertilization led to a slight decrease in the oil content of the seeds. In both regions, the fat content was greatest in the variant without fertilizer and was 39.9 and 40.9 %.

Published: December 2021

Abstract
Phosphate fertilizers are widely used for growing crops. To obtain phosphoric fertilizers, phosphoric acid purified using organic solvents, one of which is 100% tributyl phosphate, is used. The authors of the paper have chosen this solvent to obtain purified phosphoric acid. Purification from impurities included the stages of extraction and reextraction. On the basis of the re-extract and chemically pure phosphoric acid, a phosphoric fertilizer magnesium-ammonium phosphate (MgNH4PO4) was synthesized and used in the greenhouse experiment. The greenhouse experiment consisted in growing a tomato crop included three options for fertilization. A comparative analysis of the stimulating effect of magnesium-ammonium phosphate, synthesized with the use of phosphoric acid of varying degrees of purification, on the yield of tomato culture has been carried out.The paper proposes a blister-colorimetric version of the determination of phosphate ions in a blister cell containing a mixture of dry reagents in the form of a bulk. The optimal conditions for carrying out colorimetry have been selected. The proposed method makes it possible to semi-quantitatively determine phosphorus in various objects without preparing reagent solutions, using a bulk packed in an ampoule or blister, and can be used to control phosphorus consumption by plants, which, in turn, allows regulating the introduction of nutrients in the form of dressings.

Published: December 2021

Abstract
One of the ways to strengthen the immunity of animals in aquaculture is the use of immunomodulators as a food supplement. This work presents a study on the effect of the probiotics Bacillus subtilis and Bacillus licheniformis on the immunity of crayfish and fish. It was found that the use of the probiotic “Subtilis-C” as a feed supplement strengthened the immunity of narrow-clawed crayfish: the survival rate increased almost threefold in the presence of Saprolegnia parasitica in the water and the incidence of burn-spot disease (BSD) decreased. The average cytochemical coefficient (ACC) of the lysosomal cationic protein in hemocytes decreased. It appears that crayfish consume this cytotoxic protein for immune protection. In carp fed with the probiotic, the immunity to saprolegniosis was strengthened, the body weight gain increased significantly, the amount of hemoglobin increased by 15%, and the number of erythorocytes in the blood almost doubled. An increase in metamyelocytes was noted in WBC differential count of these fish.

Abstract
A substantive interpretation of the main categories of the system approach is formulated in relation to the semantics of the operation of mobile agricultural units from the standpoint of ensuring the technological reliability of the production of field mechanized work by improving the methods and means of measuring control of the state of machine and tractor units and evaluating the parameters of functional diagnostics under shift time conditions. A structural diagram of the systemic image of the production of field mechanized work is proposed, which makes it possible to clarify the hierarchical levels of movement of concepts in the field of managing the state of a complex technical system during the operation period, to highlight the object of research and establish its system elements and connections with the operating environment. The business logic of the implementation of the basic operations of the system of technological adjustment of machine-tractor units to ensure the quality of the technological operation when used for its intended purpose is presented. The theoretical significance of the work is associated with the development of a systematic understanding of the main objects of the processes of machine use in agriculture. The applied and practical significance of the work is confirmed by new technical solutions implemented in projects and organizational and technical documents of an industry scale. The results of the work can be useful both for researchers of the processes of machine-use in agriculture, and for practitioners-subjects of small and medium-sized agribusiness, as well as in organizing the transfer of knowledge of the agro-engineering direction to specialists in agricultural production.

Published: December 2021

Abstract
The relevance of the construction of ecological houses (eco-houses), i.e. houses made from environmentally friendly building materials, is increasing due to the exacerbation of environmental problems on a global, regional and local scale. The purpose of this study is considered to be the actualization of the concept of ecological houses in relation to modern conditions, taking into account new and future requirements for buildings. Ecological houses are considered as a kind of modern green buildings. Particular attention is paid to energy efficiency as an essential requirement for new buildings. Eco-friendly building materials have two qualities at the same time: they are more favorable to humans; their use has a minimal impact on the environment, taking into account the entire life cycle of the building material. As a rule, natural materials (materials of natural origin) are considered environmentally friendly. It is rationally to apply the experience of energy efficient and green construction for environmentally friendly buildings: compact architectural forms, translucent structures with the effect of passive solar heating, supply and exhaust ventilation with heat recovery, automation of engineering systems, elimination of heat bridges (cold bridges).
Justification of the rotary working bodies of the cultivator for processing between the rows of plantations of lavender oilseed on the basis of agricultural biomechanics
Authors: Babitsky L F , Sobolevsky I V , Kalafatov I I 
Published: December 2021

Abstract
The article presents the methods and results of modeling in agricultural biomechanics, which made it possible to substantiate models of cultivator working bodies adapted to the soil environment based on rotary discs with teeth. The biological prototype of this design is the burrowing limb of a rhinoceros beetle. It is proposed to solve the problems of improving the shape of rotary discs with teeth on the basis of the use of a mechanical-bionic approach, which allows to analytically describe the dependencies for determining the minimum number of steps of cutting notches between the teeth and the number of teeth on the disc, as well as the rational value of their length. The use of a new type of working bodies - a toothed flat disc, designed in a bionic manner, will increase the efficiency of weed control during inter-row tillage, and also reduce traction resistance.
