Authors: Aniskov N. I. , Safonova I. V. , Horeva V. I.
Published: June 2019

Background. In Leningrad Province, winter rye is an irreplaceable cereal crop for food and feed. At present, a reduction of the acreage under rye is observed. This situation may be changed by developing rye cultivars capable of maintaining high and stable protein content across variable natural environments.

The objective of the research encompassed 9 winter rye cultivars developed by V. D. Kobylyansky and O. V. Solodukhina at VIR, all recommended for cultivation in this area.

Materials and methods. The experimental part of the work was carried out in 2012–2017 in the fields of Pushkin and Pavlovsk Laboratories of VIR. Nine low-pentosan winter rye cultivars bred at VIR were analyzed. Sowing time was within the period from August 28 to September 11. Agricultural practice used in the experiments was conventional for the Northwestern Region. The area of the plot was 10 m2; there were three replications. Seeding rate was 350 seeds/m2 or 3.5 million viable seeds per hectare. Analysis of variance was used for mathematical processing. Parameters of adaptability, stability, plasticity and stress resistance were calculated for the “grain protein content” indicator.

Results. Protein content in grain for the studied winter rye cultivars in the environments of the Northwest region averaged 10.3% and varied from 8.7% to 12.2% depending on environmental conditions and hereditary features of the cultivars. It was confirmed by the results of the analysis of variance: the share of the ‘year of trial’ factor’s effect on protein content was 71.9%. The best conditions for increased protein content were observed in 2012, 2013 and 2016 (10.7%, 11.9% and 12.2%, respectively). The analysis of average protein content in grain showed that the cultivars ‘Ilmen’, ‘Vavilovskaya’, ‘Krasnoyarskaya universalnaya’, Novaya Era, ‘Yantarnaya’ exceeded the reference cultivar ‘Era’ by (1.0 – 10.0%). The most adaptable in the context of grain protein content under the conditions of the Northwestern Region were the winter rye cultivars ‘Ilmen’, ‘Era’, ‘Yantarnaya’, Novaya Era, and Rushnik 2. The sum of their ranks according to the coefficients of variation (V), environmental plasticity (O), relative trait stability (St²) and homeostasis (Hom), as well as each cultivar’s adaptability coefficient (AC), stress resistance level (Y min – Y max) and compensatory ability (Y min + Y max/2), was 13–31 units.

Conclusion. Rye cultivars ‘Ilmen’, ‘Era’, ‘Yantarnaya’, Novaya Era, and Rushnik 2 possess high adaptability and can maintain high protein content levels in grain under widely varied environmental conditions in the Northwestern Region of Russia.

Authors: Voytsutskaya N. P. , Loskutov I. G.
Published: June 2019

Background. For the present-day oat breeding, the task is to develop adaptive cultivars with high yield potential, high quality of products, fairly early-ripening habit, and resistance to lodging and diseases. Breeding new cultivars with a complex of valuable characters, high yield, and high quality of products under varied environmental conditions requires well-studied source material. Selection of sources according to the basic economically useful traits is one of the main objectives in the study of the global diversity preserved in the oat collection.

Results and conclusion. The article presents the results of studying the oat accessions from Western and Central European countries, preserved in the VIR collection, under the conditions of Kuban Experimental Station of VIR (Krasnodar Terr.). Evaluation of the accessions in the field was targeted at such crop characters as the duration of the growing season, resistance to lodging, and field resistance to rust diseases. A structural analysis was performed in the laboratory to measure the weight of 1000 grains, the number of spikelets and grains per panicle, grain weight per panicle and per plant, and percentage of grain hullness. As a result of a three-year comprehensive field study of the newest oat cultivars bred in Western Europe in the environments of Kuban Experimental Station of VIR, sources of traits useful for breeding were identified, such as lodging resistance, field resistance to crown rust, high yield structure components (1000 grain weight, grain weight per panicle, number of grains per panicle, grain productivity). When using source materials in oat breeding practice, in addition to economically important traits, special attention should be paid to grain size, since this character, according to our data, has the most significant correlation with the grain yield of a cultivar. The identified sources of traits valuable for breeding may be included in breeding programs of Krasnodar Territory and other regions of the Russian Federation.
Variability and correlations of economically valuable traits in cowpea from the VIR collection in the environments of Astrakhan provincer
Authors: Gurkina M. V.
Published: June 2019

Background. The problem of a deficit in vegetable protein and the need to diversify agricultural produce require involvement of new and little-known crops, such as cowpea, in the production. Cowpea (Vigna unguiculata (L.) Walp.) is a high-protein leguminous crop; its breeding and production have been intensified in Russia only in recent years. The study of the VIR collection, carried out at the Institute’s branch in Astrakhan, makes it possible to disclose the crop’s breeding potential. Objective: Studying the range of variability and tracing the relationships of economically valuable traits in vegetable (green pod) cowpea under the conditions of Astrakhan Province.

Materials and methods. In 2008‑2010, a study was implemented at an experiment plot of the Astrakhan branch of VIR. Thirty- three accessions of green pod cowpea from the VIR collection were studied to analyze the variability of 12 phenotypic traits. Positive and negative correlations were identified between the following characters: interphase periods (flowering, industrial ripeness and seed maturation), shape of the shrub, lengths of the stem and to the first pod, length and weight of the pod, number of seeds per pod, presence of a parchment layer and fiber in pod valves, pod yield per plant, number of pods and peduncles, seed weight per plant, and weight of 1000 seeds.

Results and conclusion. Medium variability was observed for such characters as the interphase periods ‘shoots–industrial ripeness’ and ‘shoots– seed maturation’, number of seeds per pod, and weight of 1000 seeds: the coefficient of variation (CV) was 15‑18%. High variation was registered for the length and weight of the pod (CV = 26‑32%), shrub shape, stem length, and length of the stem up to the first pod (CV = 35‑37%). The widest ranges of variability were demonstrated in the quantitative yield characters of cowpea accessions: number of pods per plant (CV = 33‑49%), number of flower stalks (CV = 38‑51%), and seed weight per plant (CV = 38‑44%), which means that cowpea yield is quite susceptible to weather conditions. During the three years of studying, the lowest levels of variability in economically valuable traits were characteristic of the accessions of the early-ripening group: k‑668 and k‑873 (China); mid- ripening group: k‑971 (India); and late-ripening group: k‑141 (China). Cowpea pod productivity depended to the greatest degree from mean values of the number of pods per plant (r = 0,73) and the number of peduncles (r = 0,71). The identified correlations in the productivity components make it possible to optimize the selection of accessions promising as source materials for the development of new high-yielding cultivars.
Polymorphism of the Rca2 anthracnose resistance gene in strawberry cultivars (Fragaria × ananassa)
Authors: Lyzhin A. S. , Lukyanchuk I. V. , Zhbanova E. V.
Published: June 2019

Background. Anthracnose, caused by phytopathogenic fungi of the genus Colletotrichum, is one of the most important strawberry diseases. Strawberry yield losses from anthracnose lesions can reach 80%. Most strawberry cultivars are susceptible to anthracnose. Therefore, identification of the initial forms carrying resistance genes is a necessary step toward successful breeding of anthracnose-resistant cultivars. Use of molecular markers will increase reliability of identification and enhance effectiveness of strawberry breeding.

Materials and methods. Biological material was represented by strawberry cultivars (Fragaria × ananassa Duch.) of various ecological and geographical origin. Total genomic DNA was extracted from the fresh leaves using the CTAB methods according to Puchooa (2004). To assess the allelic state of the Rca2 anthracnose resistance gene, the SCAR marker STS-Rca2_240 was used. The SCAR marker STS-Rca2_240 was multiplexed with the microsatellite marker EMFv020 used as the positive PCR control.

Results and conclusion. The SCAR marker STS-Rca2_240, mapping at about 2.8 cM from the Rca2 gene, was identified in the strawberry cultivars ‘Elianny’, ‘Troubadour’ and ‘Sudarushka’. Cvs. ‘Elianny’ and ‘Troubadour’ are presumably characterized by a dominant homozygous (Rca2Rca2) or heterozygous (Rca2rca2) genotype. Cv. ‘Sudarushka’ has the heterozygous state for the Rca2 anthracnose resistance gene (Rca2rca2). In the remaining cultivars studied, the marker STS-Rca2_240 was not detected (the prospective genotype is rca2rca2).

Authors: Shupletsova O. N. , Shchennikova I. N.
Published: June 2019

Background.The environmental conditions in the northeast of the Russian Non-Black-Soil zone require development of barley cultivars with resistance to higher soil acidity, drought and diseases. Increased productivity in stressful environments was achieved by combining different breeding techniques, including application of cell technologies.

Materialsand methods.Barley accessions from the unique collection of the N. I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR) served as sources of useful traits. These accessions underwent field- and laboratory-based research at the FASC of the North-East, which was targeted at the main qualities of breeding value: grain yield, growing season duration, and resistance to lodging, diseases and soil stress. Cultivation of callus tissues and regeneration of barley plants were performedin vitroon artificial nutrient media modified by adding selective agents simulating the effect of natural stressors.

Results and discussion.After studying the accessions from VIR for various traits of breeding value for the environments of the Volga-Vyatka region, the following breeding sources were selected: cvs. ‘Dina’ (k‑29216, Russia), ‘Andrey’ (k‑30122, Russia), etc. for their earliness; ‘Belogorsky 90’ (k‑29770, Russia), ‘Syabra’ (k‑29917, Belarus), etc. for combined high yield and earliness; ‘Musson’ (k‑30968, Russia), ‘Fenix’ (k‑30835, Ukraine), etc. for lodging resistance; ‘Dina’ (k‑29216, Russia), ‘Medikum’ (k‑30962, Russia), etc. for disease resistance; and ‘Tandem’ (k‑30883, Russia), ‘Novichok’ (k‑30806, Russia), etc. for soil stress resistance. Besides, cvs. ‘Ekolog’ (k‑29417, Russia), ‘Conrad’ (k‑30406, USA), etc. were identified as promising for cellular breeding. General principles regulating selection of initial genotypes for barley tissue culture were formulated. Of practical interest is application of cell-level breeding techniques to cultivars sensitive or moderately resistant to stressors. Accessions from VIR’s collection have been used to develop spring barley cultivars adapted to the cultivation conditions of the Volga-Vyatka region: more than 30 cultivars through hybridization and selection, and 6 cultivars with theuse ofin vitrotissue culture.

Na simulação, o docente pode intervir a qualquer momento, o que o auxilia na avaliação e instrução do estudante. O objetivo deste estudo foi avaliar a evolução da autoconfiança e segurança de estudantes após aprendizagem simulada utilizando manequim em um componente curricular de Periodontia e sua correlação com desempenho prático. Questionários utilizando escala visual analógica (EVA), escala numérica de 101 pontos (NRS-101) e escala verbal de 4 pontos (VRS-4) foram aplicados aos estudantes da Disciplina de Periodontia I da Universidade Federal do Paraná  no primeiro semestre de 2018, em três momentos: 1) antes do início das atividades práticas; 2) após a fase laboratorial; e 3) após a fase clínica. Os dados obtidos foram comparados entre si pelo tempo de aplicação e correlacionados com a nota prática final. Os estudantes demonstraram maior autoconfiança e segurança no final do que no início do período (Friedman; p<0,05). Essa evolução foi notada principalmente entre a primeira e segunda aplicações dos questionários, ou seja, após a fase laboratorial simulada em manequim. Houve correlação entre autoconfiança e segurança aferidas pela NRS-101 e o desempenho prático (Spearman; r=0,3948 e r=0,3771, respectivamente; p<0,05). Observou-se aumento de autoconfiança e segurança dos estudantes após aprendizagem simulada em manequim, que se mostrou ligeiramente mais valiosa para evolução desses quesitos em comparação à experiência clínica.

O estudo objetivou verificar a adesão dos estudantes de graduação em Odontologia à campanha de vacinação contra hepatite B e tétano em uma escola particular de Odontologia. A hipótese testada foi que a campanha de vacinação seria um programa efetivo na prevenção da infecção pelo HBV e tétano. O cartão de vacinação e o exame anti-HBs foram analisados como desfecho principal. Os dados foram submetidos à regressão de Poisson bivariada e multivariada (a<0, 5). Idade, ano de admissão, turno de estudos, número de doses de vacinas para hepatite B e vacinação para tétano foram variáveis independentes. Dos 485 estudantes, 318 entregaram a cópia do cartão de vacinação e 295 apresentaram o exame anti-HBs. A mediana de idade dos estudantes foi de 21 anos (76,1% do sexo feminino, 23,9% do sexo masculino). Nos modelos de regressão de Poisson univariada e multivariada, a não vacinação contra o tétano foi considerada fator de risco. Os alunos de graduação matriculados nos anos iniciais foram mais propensos a não receberem a vacinação do que aqueles dos anos finais (p≤0,001). Do total de alunos (318) que entregaram a documentação para hepatite B, 86,1% completaram o protocolo de vacinação (3 doses), enquanto 13,9% o protocolo incompleto (1 ou 2 doses). Os estudantes mais velhos foram mais propensos a não terem tomado as vacinas em comparação com mais jovens (p≤0,001). Em relação ao anti-HBs, 73,9% apresentaram título de proteção positivo. As campanhas de vacinação para estudantes de graduação podem ser efetivas se a adesão dos indivíduos ao calendário vacinal puder ser assegurada. Estratégias para maior adesão dos estudantes, como essa campanha, devem ser pensadas e planejadas pelos cursos de Odontologia.
APPLICATION OF FINISH-STRENGTHENING PROCESS WITH DIAMOND SMOOTHING FOR BEARING CAPACITY INCREASE OF JOINTS WITH TIGHTNESS
Authors: Шишкин Сергей , Shishkin Sergey
Published: June 2019

The test results of stress joints with a regular micro-relief with the purpose of the assessment of their operation properties increase at finish-strengthening are shown. Thus, shaft endurance in insertions increases at relief application on the surface of a bush hole. It is explained with the pressure concentration decrease caused by a fit at the expense of the growth of joint contact flexibility. A similar effect is achieved at the creation of an artificial camber of a surface with the purpose of obtaining a characteristic diagram of a con-tact load distribution. The formation of a regular relief on the shaft surface results in, besides strengthening, the insignificant increase of the fatigue strength in joints.

The static strength increase in stressed joints with the regular micro-relief is explained by the contact interaction character of an unevenness at a cross as-semblage and by the increase of an actual contact area at mechanical pressing-in. At that at reassemblies it was observed a lesser decrease of their strength. A sharp increase of bearing capacity is typical for the mating at a balance of micro-relief high-step parame-ters on contact surfaces of a shaft and a bush. The results obtained lead to the idea of the creation of joints like threaded or splined joints at transferring an axial load or a rotational moment.

At the relief formation at the expense of some metal extrusion in overflows there is a raising of a sur-face “plateau” which is used for tightness increase of loose connections and also for rejects correction during manufacturing parts.

In such a way the application of efficient tech-nologies of regular micro-relief coatings along with strengthening increases considerably fatigue and static strength in joints with tightness.

Authors: Ашуркова Светлана , Ashurkova Svetlana , Антипин Дмитрий , Antipin Dmitriy
Published: June 2019

As a method of investigations there is adopted a computer mathematical modeling based on the use of a finite element method. The choice of a type and perforation parameters is connected with the problem in the large array creation of bearing structure design models of passenger car bodies. The analysis of investigations carried out in the field of multi-variation computations has shown that the most efficient investigation method is a superelement reduction. Its use allows decreasing labor and time costs for the body design model development at the expense of the initial super-element with the perforation area for a new one.

The appraisal of the procedure offered on the choice of a body efficient bearing structure with the perforated profiles is carried out by the example of the body of a domestic passenger car according to the criteria of strength and assurance of the highest weight reduction of a bearing structure.

In the first stage of the work there are defined types and parameters of perforation possible for use in the structure. Finite element design models of car bodies are developed. On the basis of strength computation results the reinforcing elements of the structure are offered which have a margin safety for perforation application in them. Based on the analysis of car body bearing structure there is carried out a choice of an efficient unit of a finite element model which will be used as a super-element. In the next stage of the work there are developed and computed structures of car bodies with the perforation types under consideration and with the use of superelements.

The computation results have shown that maximum design stresses of car bodies for all perforation types under consideration do not exceed legitimate values. As an efficient bearing structure of a passenger car body there is adopted a car body with the sixth type of perforation ensuring the largest decrease of structure metal intensity and satisfying strength requirements.

The procedure developed can be used at designing modern bearing structures of passenger car bodies having improved technical and economic values.

Harvesting microalgae is an important part in the culture system to produce higher crop biomass. Microalga Harvesting can be done by several techniques such as centrifugation, filtration, sedimentation, flocculation, ultrasonic vibration, and using filter. The technique currently used on an industrial scale is flocculation. This technique is used because it is more quickly and efficiently. Flocculants safe materials are polymers of polysaccharide seaweed. The study was conducted to determine the efficiency of the use of flocculants from alginate, carrageenan, so that the flocculation process microalgae Dunaliella salina. Flocculation process at the 50-minute show flocculation by material alginate by 30.52%, 22.85% by carrageenan, 11 % by Agar, plankton without flocculation make flocculates only amounted to 3.96%. Flocculation process at 240-minutes unchanged where carrageenan increased flocculation becomes 39.84%. Agar increased to 31, 48%. Plankton added flocculant alginate did not experience significant changes that just turned into 30.89%. The research results Show best flocculation activity is carrageenan where flocculation speed equal to alginate that has been frequently used as flocculants.

A modified Mann iterative scheme based on the generalized explicit methods for quasi-nonexpansive mappings in Banach spaces
Authors: SOW Thierno
Published: June 2019

In this paper,  we  introduce and study a new iterative algorithm which is a combination of a modified Mann iterative scheme and a generalized    explicit methods (GEM) for finding  a common  fixed points of an infinite family of  quasi-nonexpansive mappings in Banach spaces. Under suitable conditions, some strong convergence theorems for finding  a common  fixed points of an infinite family of quasi-nonexpansive mappings are obtained without imposing any compactness assumption. Presented results improve and generalize many known results in the current literature.

Extremo: An Eclipse plugin for modelling and meta-modelling assistance
Authors: Mora-Segura Ángel
Published: June 2019

Modelling is a core activity in software development paradigms like Model-driven Engineering (MDE). Therefore, the quality of (meta-)models is crucial for the success of software projects. However, many times, modelling becomes a purely manual activity, which does not take advantage of information embedded in heterogeneous information sources, such as XML documents, ontologies, or other models and meta-models. In order to improve this situation, we present Extremo, an Eclipse plugin aimed at gathering the information stored in heterogeneous sources in a common data model, to facilitate the reuse of information chunks in the model being built. The tool covers the steps needed to incorporate this knowledge within an external modelling tool, supporting the uniform query of the heterogeneous sources and the evaluation of constraints. Flexibility of the main features (e.g., supported data formats, queries) is achieved by means of extensible mechanisms. To illustrate the usefulness of Extremo, we describe a practical case study in the financial domain and evaluate its performance and scalability.

Corruption is one of the ailments in this country, a disease like a deadly virus effects every official. In the presence of corruptors, justice is reversed. Unfortunately, people like affirming the behavior of corruptor. Officials who had been convicted by the court as robbers of state money, actually rose and were later re-elected as regents or legislatures. Whereas nthose who are honest are not even given a place, even then they will be trapped in various cases. Justice is thus no longer given space, because injustice gets a respectable place. Isn’t corruption a form of injustice that has usurped people’s rights. Because of that corruption has broken dwon the societas. With the view of Thomas Aquinas, we will see how corruption has become spaces for the occurrence of injustice in society.
