Perspectives of barley breeding for the conditions of the Volgo-Vyatka region (analytical review)
Authors: Shchennikova I. N. , Kokina L. P.
Published: February 2021

The article is devoted to the analysis of the structure of sown areas and characteristics of barley varieties zoned in the Kirov region for 2020. In 2019 in the Kirov region the varieties cultivated in production for more than 20 years had the largest specific weight – 50.1 % of the acreage occupied with barley. Those cultivated for more than 10 years had 36.1 %; from 5 to 10 years – 13.8 %. Certified sowings varied from year to year in percentage to the occupied area. There is a gradual decrease in unsorted sowings of barley from 3.0 thousand hectares in 2017 up to 1.18 thousand hectares in 2019. The areas sown with barley varieties bred in Federal Agricultural Research Center of the North East named N. V. Rudnitsky (FARC North-East) in the structure of sown areas in 2019 were from 21.5 % in the southern zone up to 57.8 % in the northern zone of the Kirov region. For the whole of the region the greatest distribution was recorded among Belarussian cultivars Zazersky 85 (39.3 % of the areas sown with barley), and cultivars bred in FARC North-East: Ecolog (10.8 %), Rodnik Prikamiya (7.1 %) and Novichok (7.0 %). In northern districts of the region the ratio changed: Ecolog – 27.2 %, Rodnik Prikamiya – 18.9 %, Novichok – 9.0 %, Zazersky 85 – 7.7 %. High productivity (4.22-4.79 t/ha in average), resistance to lodging and diseases characterize the zoned cultivars. The main disadvantage of barley assortment offered for zoning is the lack of stable yield and differences in duration of the growing season among the varieties. All cultivars belong to the group of mid-season, except for the mid-late cultivar Zazersky 85. The region is short of the sources of high-quality raw materials for forage production; only 30.7 % of all assortment of barley in the region are presented by cultivars with high grain quality (Ecolog, Belgorodsky 100, Rodnik Prikamiya and Pamyati Rodinoy). Currently, the trend for developing high-yield early, resistant to lodging and diseases barley varieties of high grain quality is to become the key factor in breeding work.

Published: February 2021

The paper presents the results of 2018-2019 research on improving the technology of growing planting material of bog cranberry (Vaccinium oxycoccos L.) of Krasa Severa, Severyanka, Virussaare varieties on the basis of in vitro. Studied was the effect of the concentrations of growth regulators in the composition of the nutrient medium according to Anderson's recipe on the reproduction and subsequent rooting of micro cuttings, as well as the duration of cultivation and adaptation of micro plants depending on partial pruning of shoots. It has been established that at the stage of introduction into in vitro culture, sterilization of explants with 33% hydrogen peroxide in an exposure of 5-8 minutes with washing in 5 portions of sterile distillate gives 60-80 % of viable shoots. The optimum phase of plant development for the successful introduction of in vitro culture is the swelling of buds. Cultivation of micro cuttings was carried out in a light room at a temperature of 25±2 °С, a photoperiod of 16 hours. The duration of each subculturing was 30-60 days. For the stage of actual micropropagation on Anderson's nutrient medium, an increase in the dose of cytokinin 6-benzylaminopurine (6-BAP) from 0.2 to 0.5 mg/l and an increase in the duration of cultivation from 30 to 60 days contributed to a significant increase in the multiplication factor on average for the tested cranberry varieties.According to the efficiency of micropropagation, the varieties Virussaare and Krasa Severa were distinguished – 9.3-12.0 pcs/stalk, respectively. At the rooting stage, the use of a root-forming reagent of indolyl-3-acetic acid (IUK) in doses of 0.2, 0.5 and 1.0 mg/l in the composition of Anderson's nutrient medium did not affect the quality of root formation and the length of shoots of Virussaare micro-plants. No significant varietal differences in the root-forming ability of microcuttings were found. The tendency of better rooting of micro cuttings was observed in the Virussaare variety (90.3 %) compared to the Severyanka (85.7 %) and Krasa Severa (79.3 %) varieties. Micro plants of the Krasa Severa cultivar were characterized by the longest shoots, the total number of roots was less, but their length was longer in comparison with other cultivars. For the adaptation stage, a substrate from a mixture of lowland peat and sphagnum moss was used (1:1). The efficiency of adaptation of micro plants of cranberry varieties when cutting the tip of the shoots was 100 %. Pruning of micro plants shoots contributed to the formation of more side shoots and better development of the aboveground part of the plants.
Does Corruption Affect Foreign Direct Investment (FDI) Inflows in SADC Countries?
Authors: Chamisa Moses Garai
Published: February 2021

Foreign Direct Investment (FDI) is a crucial factor to development in SADC, while at the same time corruption continues to be an obstacle to economic transformation in these countries. Empirically, studies provide controversial results on the effect of corruption on FDI. Some studies conclude that corruption negatively impacts FDI inflows in a country, while others provide evidence that corruption can act as a ‘helping hand’ to FDI inflows in a country. Given this ambiguity in the results of previous studies, using panel data for the period 2000-2016 for 15 SADC countries, this study examines the impact of corruption on FDI inflows in these countries. Lack of attention in previous studies on the impact of corruption on FDI inflows in SADC motivated this research. Estimation results using robust random effects model show that when corruption is widespread in a country, foreign investors are reluctant to invest. Thus, corruption negatively affects FDI inflows in SADC countries. The study recommends that SADC countries should develop and implement efficient, effective and strong anti-corruption measures to reduce corruption and hence increase FDI inflows.

Published: February 2021

Universities around the world are incorporating online learning, often relying on videos (asynchronous multimedia). We systematically reviewed the effects of video on learning in higher education. We searched five databases using 27 keywords to find randomized trials that measured the learning effects of video among college students. We conducted full-text screening, data extraction, and risk of bias in duplicate. We calculated pooled effect sizes using multilevel random-effects meta-analysis. Searches retrieved 9,677 unique records. After screening 329 full texts, 105 met inclusion criteria, with a pooled sample of 7,776 students. Swapping video for existing teaching methods led to small improvements in student learning (g = 0.28). Adding video to existing teaching led to strong learning benefits (g = 0.80). Although results may be subject to some experimental and publication biases, they suggest that videos are unlikely to be detrimental and usually improve student learning.

Identifiability as an “Antidote”: Exploring Emotional Contagion and the Role of Anonymity in Twitter Discussions on Misinformation
Authors: Chen Chen , Yuan Hao , Yao Mike
Published: February 2021

Misinformation carries both distorted facts and sophisticated emotional signals. Comparing to facts that could be labeled as true or false, we are more concerned about contaminative negative emotions transferring digital-ly among users. In this study, we explored an emotional contagion effect among misinformation discussion participants on Twitter. We analyzed the sentiment of 573 tweets in 192 discussion threads. Our result revealed that highly emotional tweets do not have a universal effect on the online discussions, but it affects those individuals with limited social and personal identity cues (i.e., being anonymous). We found that anonymous members of the online discussion are more susceptible to emotional contagions than those are not. We also suggest coping strategies that protect social media users’ emotional well-being during the era COVID-19.

TUBE1 is a differentially expressed gene in brain metastatic human breast cancer.
Authors: Mamoor Shahan
Published: February 2021

Metastasis to the brain is a clinical problem in patients with breast cancer (1-3). We mined published microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with brain metastasis in humans with metastatic breast cancer. We found that tubulin epsilon 1, encoded by TUBE1, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. TUBE1 mRNA was present at decreased quantities in brain metastatic tissues as compared to primary tumors of the breast. Importantly, expression of TUBE1 in primary tumors was significantly correlated with patient overall survival. Modulation of TUBE1 expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain in humans with metastatic breast cancer.

Large Phase 3 clinical trials of the two FDA-authorized COVID-19 vaccines, mRNA-1273 (Moderna) and BNT162b2 (Pfizer/BioNTech), have demonstrated efficacies of 94.1% (n = 30,420, 95% CI: 89.3-96.8) and 95% (n = 43,448, 95% CI: 90.3-97.6) in preventing symptomatic COVID-19, respectively. Given the ongoing vaccine rollout to healthcare personnel and residents of long-term care facilities, here we provide a preliminary assessment of real-world vaccination efficacy in 62,138 individuals from the Mayo Clinic and associated health system (Arizona, Florida, Minnesota, Wisconsin) between December 1st 2020 and February 8th 2021. Our retrospective analysis contrasts 31,069 individuals receiving at least one dose of either vaccine with 31,069 unvaccinated individuals who are propensity-matched based on demographics, location (zip code), and number of prior SARS-CoV-2 PCR tests. 8,041 individuals received two doses of a COVID-19 vaccine and were at risk for infection at least 36 days after their first dose. Administration of two COVID-19 vaccine doses was 88.7% effective in preventing SARS-CoV-2 infection (95% CI: 68.4-97.1%) with onset at least 36 days after the first dose. Furthermore, vaccinated patients who were subsequently diagnosed with COVID-19 had significantly lower 14-day hospital admission rates than propensity-matched unvaccinated COVID-19 patients (3.7% vs. 9.2%; Relative Risk: 0.4; p-value: 0.007). Building upon the previous randomized trials of these vaccines, this study demonstrates their real-world effectiveness in reducing the rates of SARS-CoV-2 infection and COVID-19 severity among individuals at highest risk for infection.

Geological risk management
Authors: Khan Aftab Alam
Published: February 2021

Geological risk management depends on the understanding of the underlying geological processes and their control on various geohazards. The significant responsibilities are post-crisis analysis with scenario formulation to develop strategies to mitigate the impact of future events and preparation of coordinated risk assessments for regions vulnerable to natural hazards. The evaluations are essential for developing hazard-resistant structures, building codes, better land use planning, hazard minimising policy, and emergency response plans. Two vital geological hazard scenarios, such as earthquake and arsenic contamination in groundwater in the Ganges-Brahmaputra-Meghna delta of Bangladesh, are elaborated as case studies. A complete cycle of seismic hazard assessment to seismic risk management is proposed. An earthquake prediction to risk management mechanism is identified together with the coordinated professional effort is for seismic risk assessment. The geological processes responsible for arsenic contamination in groundwater are pointed out and the role of geology in managing various geohazards is highlighted.
Earthquake-induced slope vibration and its relationship with material properties, slope height, and input wave frequency
Authors: Dhakal Subodh , Hack Robert , Huismann Marco
Published: February 2021

The relationship of the amplification of vibration on the surface with the slope geometry, earthquake input signal (mainly frequency of the wave) and the material property of the slope is studied using the finite difference program FLAC. A sinusoidal wave with acceleration of 1 m/s2 is applied for the duration of 0.25 sec. The influence of varying input frequency is investigated applying the frequencies in the range of 3 Hz to 15 Hz. The variation of amplification due to the change in shear modulus of the material in the slope and that due to slope height is also investigated.

It is found that the crests of the higher slopes are amplified most by the lower input frequency and smaller slopes are amplified most by the higher input frequency. The overall magnitude of the amplification is maximum for smaller slopes when input signals of higher frequency are applied. The generation of standing waves at certain harmonic frequencies could be the reason behind such a high amplification. It is also seen that the amplification peaks of vibrations repeat at different slope heights, which is considered reflection of the harmonic effect. A clear resonance effect is seen when the amplification of vibration is plotted against the shear modulus. The peaks of such amplification also repeat periodically as a result of varying shear modulus. Present study provides some preliminary relationship of amplification with slope height and shear modulus of the material in the slope. The horizontal amplification of vibration as much as 17 (horizontal acceleration in the order of 1.7 g) is obtained at the crest of normal limestone slope with 20 m height when an input signal of 15 Hz frequency is applied. It is also revealed that for extremely lower values of shear modulus, there is mostly attenuation instead of amplification and for extremely high values of shear modulus, amplification is negligible as compared to the certain range of intermediate shear modulus. Maximum amplification in the order of 6.5 (horizontal acceleration of 0.66 g) is achieved for the shear modulus of 3000 MPa with slope height of 40 m when the input acceleration of 0.1 g is applied. This type of relationship is believed to have great importance for seismic microzonation study as the results might be used along with the digital elevation model for separating different zones of hazard levels. However, one should be aware that this result is for the slope with particular combination of material properties, geometry and earthquake input signals, and generalisation could lead to misleading results.
Natural and anthropogenic factors of flooding in the Saptakoshi alluvial fan, east Nepal
Authors: Thakur Pramod Kumar , Tamrakar Naresh Kazi
Published: February 2021

The Saptakoshi alluvial fan (SAF), located in front of the Sub Himalaya near the Chatara village, is one of the largest fans in the world. Floods bring about severe loss of lives and property in the middle and lower reaches of the Saptakoshi River. This paper attempts to assess the natural as well as anthropogenic factors responsible for flooding in the SAF. Some of the major factors of flooding are continuous and high-intensity monsoon rainfall, huge discharge of the Saptakoshi River, unconsolidated sediments and soft rock constituting steep slopes, deforestation, and land degradation. A risk zonation map of the SAF was prepared by analysing these factors, and the SAF was classified into low, medium, and high risk zones. The villages situated in the south-western part of the SAF (i.e., Belardaha, Bhardaha, Joginia, Hanumannagar, Birpur, and Tilathi) lie in a high risk zone, whereas those lying in the eastern portion (i.e., Chatara, Mahendranagar, Singra, lnaruwa, and Diwanganj) belong to a low risk zone. The flood risk level on the south-western bank is high mainly because of water impoundment by the barrage and indiscriminate release of floodwater towards the western flank of the Saptakoshi River.

Purpose: justification of the need for irrigated lands inventory and their allocation into a separate category as the main component of the agricultural landscape that forms the ecological stability and sustainability of agricultural production. Materials and methods. The research was carried out within the boundaries of Svetloyarsk district Volgograd region. The object of research is a semi-desert zone of light chestnut soils. The research was carried out using aerospace observation methods in combination with geoinformation technologies and computer modeling. As a result of computer processing and transformation of space photographs, an overview space photomap of the research region is created, on which a coordinate grid, boundaries and additional attributive information are plotted. For geoinformation analysis and implementation of data processing, the QGIS 3.12 software package was used. The images were obtained from the Sentinel-2, Landsat-8 or Landsat-7 satellites, and they make it possible to carry out the whole complex of studies related to obtaining information on the state of agricultural land. Results. The location, boundaries and actual use of 2355 plots of arable land have been determined, of which 1424 are irrigated. The features of each specific site, namely the area, minimum and maximum slope angles, elevation differences and other characteristics have been determined, which made it possible to determine the suitability of these sites for irrigation purposes more accurately. Conclusions. Clarification of the nature and intensity of the use of land plots, of which more than 60 % are irrigated, requires their detailed inventory and tracking of ongoing changes. The maximum (1071 hectares) and minimum (0.7 hectares) areas of irrigated areas, the maximum slope angle of 8.18 grade, the vertical drop up to 131 m and the configuration characterize the course of erosion processes during irrigation. The discrepancy in the areas within the boundaries of Raygorodsky rural settlement was 148.26 hectares, which reflects the real picture of the irrigated lands use and availability.

Purpose: development of a computer algorithm for a quantitative assessment of the hydraulic parameters of an irrigation and drainage system with the possibility of integrating different irrigation methods. Materials and methods. The design of structures for combined irrigation is based on hydraulic calculation. A feature of such systems is the ability to change irrigation methods, which is associated with a significant change in hydraulic parameters and the complication of hydraulic design of structures. Automation of hydraulic calculations based on a universal computer algorithm is the most acceptable way to solve the problem and the basis for designing combined irrigation systems. Results. A feature of the proposed algorithm for determining the quantitative parameters of the combined irrigation system is the use of a step-by-step approach followed by the formation of a generalized hydraulic screenshot of the entire structure. A screenshot of hydraulic parameters here means a quantitative assessment of hydraulic indicators for all nodal points of a structure, implemented by a calculation method for given, stationary modes of system operation. A set of this kind of static screenshots allows you to evaluate the process in dynamics, as well as to carry out comparative assessments of hydraulic parameters under different operating modes of the combined irrigation system. The algorithm offers an original way to identify objects based on the use of a linear coordinate system. The method makes it possible to organize an enumeration of the structural elements of the system and a step-by-step calculation of hydraulic parameters from the inlet section of the design segment to any given nodal point. Conclusions. The calculation results according to the proposed algorithm make it possible to form a specially organized data array, which is a set of symbolic-numeric values that determine the pressure level and water flow rate and identify them with the nodal point of the system.

Materials and methods. A collection of soybeans, numbering 2 thousand varieties of various ecological and geographical origin, including the selection of the Federal State Budgetary Scientific Institution VNIIOZ, created in 1983 and annually replenished with new genotypes. Hybridization and selection in later generations. The research was carried out on the chernozem soils of Volgograd region. Results. The original plant varieties were identified in the period 2008–2010, competitive variety trials were carried out in 2014–2016, state tests were held in 2018 and 2019. A new soybean variety called Volgogradka 2 has been included in the State Register of Varieties approved for use since 2020. In accordance with the indicators of its comparative with the standard characteristics, it stands out for its high yield (3.04 t/ha (an increase of 0.34 t/ha)), a short growing season (105 days), medium-sized (0.74 m) plants with a high attachment of lower beans (0.16 m), an increased protein content in seeds (41 %) and a gross crude protein and fat yield of 1.51 t/ha. It is drought-resistant in non-irrigated agriculture of the steppe zone of chernozem soils of Volgograd region, highly profitable and provides high-quality grain production suitable for food processing. Conclusions. A fundamentally new soybean variety with a complete type of stalk growth during the period of mass flowering, a low stem that is resistant to lodging and high attachment of lower beans, a short growing season, which contributes to a significant increase in the grain yield and quality in terms of protein content relative to standard varieties VNIIOZ 76 and VNIIOZ 86 was developed by traditional methods of breeding. The introduction of the new variety will allow expanding soybean crops in the Lower Volga region and increasing domestic soybean production.

Purpose: to study the effect of the desalinator “Biosolvent” on the processes of soil desalinization during the washing and vegetative irrigation. Materials and methods. The research was carried out in Syrdarya region of Uzbekistan at experimental sites. The objects of research are saline soils of irrigated fields under cotton. Field observations and soil analyzes were carried out according to generally accepted methods: granulometric composition – by sedimentation method, salinization – by electrical conductivity and water extract, phenological observations – by the SoyuzNIKHI method. Statistical processing was performed in Excel. Results: when spraying soil of strong and medium salinity with 10% Biosolvent preparation before washing and watering cotton, the leaching of ions toxic to plants is higher compared to conventional washing, more harmful ions are washed out: chlorine by 35–42 %, sulfates by 13–16 %, calcium by 21–28 %, sodium by 21–23 %. When treating the surface of furrows with a 10% solution before watering cotton, a more significant decrease in the content of harmful salts was also found than with conventional irrigation. Salts were washed out along the treated furrows by 18–23 % more, and chlorine, sulfate and calcium ions, respectively, by 17, 18 and 14 %. As a result of improved conditions in the root zone of cotton, an increase in yield of 7.5 c/ha was obtained. Conclusions. To increase the efficiency of washing saline soils and regulate the salinity of the root layer of soil during the growing season, it is advisable to apply preliminary spraying of the soil with a 10% solution of the “Biosolvent” preparation. The use of Biosolvent in comparison with traditional technologies contributes not only to a decrease in soil salinity, positive changes in chemical composition of salts in the soil, but also to an increase in cotton yield.
El origen del ‘sueño’ de la arquitectura de cristal. Una aproximación
Authors: Rubio Hernández Rosana
Published: February 2021

La historia de la arquitectura de vidrio se ha visto animada por un ‘sueño’ estimulado por las particulares propiedades de interacción de este material con la luz. El artículo se aproxima a la génesis de ese sueño y sus primeras manifestaciones, en forma de leyendas sobre fantásticos edificios de cristal transcritas en textos sagrados o literarios, y hace referencia a las arquitecturas en las que se ha materializado y a algunos de los arquitectos a los que ha inspirado. Se concluye que la pervivencia en el tiempo de este sueño, se debe a la capacidad otorgada al vidrio como vía para acceder indistintamente a ‘anagogías'(elevación y enajenación del alma por la contemplación de las cosas ‘divinas’) de carácter religioso o laico.

Obwohl immer mehr Bildungsausländer*innen an deutschen Hochschulen studieren, ist über die Einflussfaktoren auf ihren Studienerfolg bisher wenig bekannt. Da sie besonders gefordert sind, den Lernstoff eigenständig vor- und nachzuarbeiten, untersuchte die vorliegende Studie ihr Nutzungsverhalten kognitiver und metakognitiver Lernstrategien als Schlüsselkomponenten selbstregulierten Lernens und deren längsschnittliche Effekte auf Studienzufriedenheit und Abbruchintention. Anhand latenter Profilanalysen wurden bei N = 3,837 Bildungsausländer*innen vier Lernerprofile (Maximal-, Tiefen-, Durchschnitts- und Minimallerner) im ersten Studiensemester ermittelt und ihre prospektive Vorhersagekraft für die Studienzufriedenheit und Abbruchintention am Ende des ersten Studienjahres bestätigt. Aus den Befunden lassen sich Implikationen für die Gestaltung von (profil-)spezifischen Trainings- und Unterstützungsangeboten für Bildungsausländer*innen in Deutschland ableiten.
responsabilidade civil dos provedores de internet nos casos de pornografia de vingança

Published: February 2021

O fenômeno da pornografia de vingança possui na internet seu mais expressivo instrumento de realização, cuja prática é, inclusive, fomentada por provedores de internet. Dado a isso, questiona-se: em que medida o direito brasileiro regula a responsabilidade civil dos provedores de internet nos casos de exposição de pornografia de vingança? Intenta-se, com isso, analisar o alcance da legislação brasileira, em especial o Marco Civil da Internet, na resposta do fenômeno de exposição indevida da intimidade, sobretudo de mulheres. Para isso, efetuou-se uma pesquisa pelo método hipotético-dedutivo, com a revisão de bibliografias e legislativa. Sendo assim, trabalha-se a pornografia de vingança como expressão de violência de gênero, porquanto a mulher é constantemente julgada pelo exercício de sua sexualidade. A principal evidência deste estudo é que os provedores de internet, especificamente os de conteúdo, devem responder de forma objetiva pela participação no dano advindo da pornografia de vingança vinculada em suas bases.
