Bayesian approach for quantifying silica fume and water reducer impact on creep of concrete
Authors: Zgheib Elise , Raphael Wassim , Matar Pierre , Moukarzel Ibrahim
Published: September 2017

The behaviour of concrete structures is affected by the time-dependent volume changes of concrete caused by sustained loads and moisture loss. Creep deformations have an important effect on long-term integrity of reinforced concrete structures. Incorrect or inaccurate prediction of these volume changes leads to undesirable and harmful consequences for the structures. Knowing that the Eurocode 2 does not take admixtures and additives into consideration in predicting creep deformations, the aim of this study is to apply correction coefficients to the Eurocode 2 creep formulas to take into account the effect of additives and admixtures, especially silica fume and water reducer. A large database from international laboratories and research centres is used in this study. The first step consists of comparing experimental measurements of creep deformations with creep values predicted by the Eurocode 2 formulas. The second step lies in introducing correction coefficients to the creep formulas of Eurocode 2, taking into consideration the percentage of admixtures and additives. These new correction coefficients are introduced in the Eurocode 2 formulas using an approximate Bayesian computation method based on a rejection algorithm.
Does Feedback Design Matter? A Neurofeedback Study Comparing Immersive Virtual Reality and Traditional Training Screens in Elderly
Authors: Kober Silvia Erika , Reichert Johanna Louise , Schweiger Daniela , Neuper Christa , Wood Guilherme
Published: September 2017

Neurofeedback (NF) is a Brain-Computer Interface (BCI) application, in which the brain activity is fed back to the user in real-time enabling voluntary brain control. In this context, the significance of the feedback design is mainly unexplored. Highly immersive feedback scenarios using virtual reality (VR) technique are available. However, their effects on subjective user experience as well as on objective outcome measures remain open. In the present article, we discuss the general pros and cons of using VR as feedback modality in BCI applications. Furthermore, we report on the results of an empirical study, in which the effects of traditional two-dimensional and three-dimensional VR based feedback scenarios on NF training performance and user experience in healthy older individuals and neurologic patients were compared. In conclusion, we suggest indications and contraindications of immersive VR feedback designs in BCI applications. Our results show that findings in healthy individuals are not always transferable to patient populations having an impact on serious game and feedback design.
Evaluation of Spatial Perspective Taking Skills using a Digital Game with Different Levels of Immersion
Authors: Freina Laura , Bottino Rosa , Tavella Mauro , Chiorri Carlo
Published: September 2017

The present paper presents the results of an experiment aimed at assessing the impact of different levels of immersion on performance in a Spatial Perspective Taking (SPT) task. Since SPT is an embodied skill, the hypothesis was that the more immersive a tool is, the better the performance should be. Ninety-eight students from a local primary school have played with three different versions of a game: (i) completely immersive with a Head Mounted Display, (ii) semi immersive on a computer screen and (iii) non-immersive where no movements were possible for the player. Results showed that in the immersive versions of the game, players obtained higher scores than in the non-immersive version, suggesting that an immersive tool can better support performance in a SPT task.

An uncritical encounter between anthropology and psychiatry
Authors: Singh Bhrigupati
Published: September 2017

In what ways do two bodies of knowledge meet? Anthropology and psychiatry most often meet in a mood of mutual suspicion, the danger of which is that each confronts (or avoids) the other as a straw man. In this introduction I describe a refreshingly different encounter in which a group of psychiatrists from the All India Institute of Medical Sciences in Delhi respond to an anthropological text, Veena Das’s 'Affliction: Health, Disease, Poverty', which engages with lives and issues quite similar to those encountered by these psychiatrists in their clinical practice. Rather than rehearsing relatively predictable debates (for instance on the importance, or lack thereof, of ‘culture’, often assumed to be the sole meeting ground between anthropology and psychiatry), what is instead surprising in the psychiatrists’ engagement with Affliction is their recognition of a shared terrain of uncertainty and complexity that moves across the realms of the spiritual, the ‘vernacular’ uses of biomedical terms, and the political economy of health. I outline three domains of inquiry that this interdisciplinary discussion opens up as regards the study of mental health and illness: 1) ecologies, circuits, and tempos rather than institutions and subjectivity; 2) not-yet ontologies and etiologies; and 3) methodological consequences, beyond quantitative/qualitative divides and towards patterns, singularities, and modes of attunement.
The language of suffering
Authors: Deb Koushik Sinha , Singh Swarndeep
Published: September 2017

The recently published book 'Affliction' by Veena Das explores the meaning of normalcy, illness, suffering, and loss in the lives of the marginalized urban poor living in and around India’s capital city of Delhi. The language that evolves in such communities to describe the afflictions of the body forms from an amalgamation of terms derived from medical, spiritual, and faith-based systems, resulting in a unique vocabulary that needs to be understood by the clinical service provider. This think piece is a psychiatrist’s interpretation of an anthropological exploration of the understanding of various illness experiences. The commentary focuses primarily on the introductory chapter of the book, entitled ‘How the Body Speaks’, and discusses the various themes and theorizations offered by Das regarding communication about illness. The book and the chapter complement and broaden the biomedical understanding of what constitutes sickness and cure for the vulnerable and the disadvantaged.
Illness narratives of substance users from urban India
Authors: Singh Shalini
Published: September 2017

Reading Veena Das’s book 'Affliction: Health, Disease, Poverty' was a journey of revelations for me as a health professional. The various dialects of illness that are spoken in the rapidly urbanizing Indian community become coherent, lending a voice to the distinctive sociocultural distress of the men and women who form a part of it. A discussion of the social aspects of illness brings certain questions to mind: Does the medical community fully understand those it tries to help? Is the therapeutic dialogue about the social dimensions of medical problems or vice versa? How do we bridge the mental health gender gap in our societies? To try and find some answers, I present the illness stories of two women who sought treatment at drug abuse treatment clinics in the urban slums of New Delhi. This think piece describes substance use disorder in the context of the cultural processes that have shaped these women, their families, and society.
Is Law Enforcement in South Africa Losing the Fight Against Commercial Crime?
Authors: Budhram Trevor , Geldenhuys Nicolaas
Published: September 2017

The South African Police Service (SAPS) is finding it increasingly difficult to protect victims from the scourge of commercial crime which threatens the economy, corrodes scarce and valuable resources, and inhibits growth and development. Official statistics from the SAPS show that the annual detection rate in respect of reported fraud cases was 35.77% in 2014/15 and 34.08% in 2015/16. Although the detection rate for serious commercial crime for 2014/15 is reported as 94.8% and 96.75% for 2015/16, it is likely that these figures are inaccurate and in reality are much lower. This article provides an overview of the incidence of commercial crime, assesses the detection rate reported by the SAPS and seeks to determine whether they are losing the fight against these crimes.
Analysis of 8th Grade Students' Viewpoints to the Concept of Democratic Citizen through Metaphors
Authors: Karabulut Gizem , Çelik Hülya
Published: September 2017

In this study, it is aimed to determine the view of the 8th grade students on the concept of democratic citizens through the metaphors. In the research towards the general objective, one of the qualitative research designs phenomenology was used. The participants of the survey are 160, 8th grade students in the Körfez district of Kocaeli province in the academic year of 2016-2017. Of the 8th grade students who participated in the survey, 85 are boys and 75 are girls. Data have been reached with semi-structured forms. The metaphors and explanations written by the students were used as the basic data source in this research. Data were analyzed through content analysis. The findings from the research show that 8th grade students perceive democratic citizenship in eight categories: freedom, justice, unity and solidarity, participation, equality, patriotism, diligence and responsibility. When the opinions of the students are analyzed, it is seen that the metaphors they produce concentrate on the categories of freedom and justice. In this context, with 13 students the most widely used metaphor is “fair citizen”. Besides the students produced metaphors mostly in the category of freedom. With “tree “and “free bird” metaphors they emphasized dimension of freedom of democratic citizenship. Students have also mentioned the distinctive characteristics of democracy, such as decision-making, election, voting, and having a saying
Leadership and Job Satisfaction: Adjunct Faculty at a For-Profit University
Authors: Barnett Donald
Published: September 2017

There is a lack of research in the for-profit sector of higher education in the United States. Likewise, there is a lack of research on the factors that affect the job satisfaction of adjunct faculty. To address these gaps in knowledge, a quantitative correlational study was performed to investigate the effect of administrative leadership on the job satisfaction of adjunct faculty who teach online classes at a for-profit university in the United States. The Multifactor Leadership Questionnaire, which measures perceived leadership behaviors, and Spector’s Job Satisfaction Survey, which measures job satisfaction, were used to anonymously collect data from a sample of 77 adjunct faculty. The Full-Range Leadership, which is composed of transformational, transactional, and laissez-faire leadership behaviors, was the theoretical model for leadership. Pearson’s product moment correlational analyses were performed to investigate the bi-variate relationships between the variables. The dependent variable of total satisfaction had a statistically significant, direct and strong correlation with the independent variable of transformational leadership (r = .536, p < .0005). The strength and direction of the relationship indicated that increases in the scores of total satisfaction are associated with increases in scores in transformational leadership. Total satisfaction had a statistically significant, indirect and moderate correlation with the independent variable of laissez-faire leadership (r = -.372, p = .001). The strength and direction of the relationship indicated that lower total satisfaction scores are associated with higher laissez-faire leadership scores. There was no statistically significant relationship between transactional leadership and overall job satisfaction.
Influence Factor of Tertiary Students’ Employability Awareness Adjust Industry 4.0
Authors: Chou Chun-Mei , Shen Chien-Hua , Hsiao Hsi-Chi , Shen Tsu- Chuan
Published: September 2017

This study aims to analyze the correlation (N=621) among tertiary students’ career planning, e-recruiting adoption acceptance, and employability awareness in Taiwan. Tertiary students’ perceived career planning includes four factors, namely, self-appraisal, job expectancy, goal selection, and problem solving. E-recruiting adoption acceptance includes four factors, namely, playfulness, ease of use, effectiveness, and usefulness. Employability awareness includes four factors, namely, personal adaptability , employability ambition, career identity, and labour market. Participants responded to a 5-point Likert-type scale for each factor. Analysis was conducted using the structural equation modeling (SEM), and a good model fit was found for both the measurement and structural models. Research findings demonstrate that tertiary students’ career planning significantly and directly influences employability awareness. Career planning significantly and indirectly influences employability awareness by e-recruiting adoption acceptance. Tertiary students’ career planning and e-recruiting adoption acceptance fit the influence model and empirical data of employability awareness. Implications of this study, including the value of student self-assessment of their skills and utility of the e-recruiting to underpin personal career development planning and inform graduate recruitment processes, are discussed and recommendations made.

Authors: Hafner Nascimento Fábio Simões , Cavalcante Luciana Ricarte , Zarife André Sant'Anna , Brito Luciara Leite , Silva Clara Dominguez , Maia Helena Fraga
Published: September 2017

Objective: To investigate the factors associated to the history of acute myocardial infarction (AMI) in hypertensive patients attended at Primary Healthcare (PHC) units. Methods: A cross-sectional study was performed in a health district in the city of Salvador, Bahia, between May and September, 2013.  Primary data was collected through trained interviewers. The magnitude of the association was estimated using the OR calculation, adopting the CI of 95%. Subsequently, multivariate analyses were carried out using logistic regression.  The project was approved by CEP/UNEB (CAAE 09656012.0.0000.0057) and financed by PRO/PET-Saúde, 2012. Results: There were 297 hypertensive patients and, among these, 243 (81.3%) were of the female gender and had average age of 56 years (± 11.54). It was observed that 35 (11.8%) reported having suffered AMI. The risk factors associated the prior AMI were concomitant Diabetes Mellitus (DM) (OR=2.19; CI95% 1.03 – 4.68) and not being aware of the existence of health education groups (OR=5.31; CI95% 1.39 – 20.20); while the protection factors were absence of central obesity (OR=0.43; CI95% 0.20 – 0.95), taking part in health education groups (OR=0.19; CI95% 0.05 – 0.73) and having had an electrocardiogram during the past 06 months (OR= 0.37; CI95% 0.15 – 0,92). Conclusion: A high percentage of hypertensive patients with a background of AMI which was associated to the diagnosis of DM, central obesity, not having had periodic electrocardiograms and not having participated in health education groups.  Strategies for the promotion of healthcare with the population and outpatient care may be considered as effective actions for the prevention of AMI.

Parameters for MDBK cell growth on microcarriers and BoHV-1 virus production
Authors: Freitas Ethel C. , Mozzer Otto D. , Freitas Carla M. B. , Costa Adelson G. , Mendonça Ronaldo Zucatelli
Published: September 2017

Bovine herpes virus 1 (BoHV-1) is an important veterinary agent , which causes infectious bovine rhinotra-cheitis. This disease affects the respiratory tract or genitals, causing weight loss, reduced milk production and abor-tion. Several vaccines against BoHV-1 have been developed. In this paper, we study the parameters for MDBK growth on microcarriers (Cytodex 1) and for BoHV-1 virus production. The cell culture attached to microcarriers is an effi-cient method to enlarge the surface of cell growth and for large-scale cell production. Our studies reveal that MDBK adhered to MCs in 30 minutes and that initial agitation of culture did not influence on the efficiency of adhesion or cell growth. In our experiments, we detected no relevant influence of agitation on initial cell adhesion of MDBK to MCs. The maximum cell yield was similar to all initial conditions of agitation studied. The maximum yield obtained in culture started with 15, 20 and 30 cells / MC, was respectively.8.7 x105, 9.3 x105 and 9.8 x105 cells / ml . The cellular distribution on the MCs at the beginning of the culture was more heterogeneous in higher initial densities. After three medium exchanges during MDBK cell culture, the increase in the final yield was 100% higher than that from culture performed without medium change (0.93 x 106 cells / mL). Replacing 50% of the culture medium with fresh medium after 24 hours of growth, the concentration of glucose (5 mM) and glutamine (1.8 mM) were almost completely res-tored. In these studies, BoHV-1 infections of MDBK were performed after 48, 72 and 86 hours with daily exchanges of 50% of the medium. The increase in viral titer was proportional to the number of viable cells present at the time of infection. The best result of BoHV-1 production was achieved when the infection was performed from 86 hours of cell culture, reaching about 3.7 x108 (TCID50/ml) after 24-48 hours of infection, being on average four times higher when compared to the culture in which the infection was performed with 48 hours of culture and approximately 2 times greater than the crop whose infection occurred after 72 hours of culture. The best yields are obtained when viral infections were performed on cultures with higher cell densities. The best result for the production of BoHV-1 occur-red with 10 MOI, 48 hours after infection, which yield was 24 and 41% superior to the MOI 0.1 and 1, respectively.
Narrating Global Order and Disorder
Authors: Levinger Matthew , Roselle Laura
Published: September 2017

This thematic issue addresses how strategic narratives affect international order. Strategic narratives are conceived of as stories with a political purpose or narratives used by political actors to affect the behavior of others. The articles in this issue address two significant areas important to the study of international relations: how strategic narratives support or undermine alliances, and how they affect norm formation and contestation. Within a post-Cold War world and in the midst of a changing media environment, strategic narratives affect how the world and its complex issues are understood. This special issue speaks to the difficulties associated with creating creative and committed international cooperation by noting how strategic narratives are working to shape the Post-Cold War international context.
La figura pedagógica de Marco Aurelio en la obra de Herodiano

Reflexões sobre a medicina romana
Authors: Mudry Philippe
Published: September 2017

O artigo busca responder à questão sobre os traços que caracterizariam o que uma historiografia especializada usualmente denomina de “medicina romana”. A partir de excertos da obra De Medicina (Sobre a medicina), único texto sobrevivente do enciclopedista latino Aulo Cornélio Celso (século I d.C.), são evocados alguns autores médicos gregos que antecedem Celso para apresentar as semelhanças e particularidades dos autores latinos que trataram da medicina. Conclui-se que, se houve uma medicina legitimamente “romana”, ela deve ser considerada como fruto do mundo rural latino, com suas receitas e terapias tradicionais, não se igualando aos avanços obtidos pela medicina grega, mas que não se eximiu, todavia, de uma rica reflexão acerca da arte médica e do papel do médico.
Technik und Weiterentwicklung der multiplen Korrespondenzanalyse

Nach der Darstellung der Technik der multiplen Korrespondenzanalyse wird gezeigt, daß die multiple Korrespondenzanalyse insbesondere bei der Analyse von qualitativen Merkmalen mit vielen Ausprägungen geringe prozentuale Erklärungsbeiträge der Faktorenachsenund damit geringe globale Erklärungsgüten niedrigdimensionaler Faktorenräume liefert. Die zur Erhöhung der relativen Erklärungsbeiträge der Faktorenachsen von Greenacre (1993) vorgeschlagene Methode der Achsen-Reskalierung wird dargestellt und numerisch beurteilt. Greenacres Joint Correspondence Analysis motiviert im Anschluß die Weiterentwicklung der Korrespondenzanalyse über direkte Kommunalitätenschätzer.
Eine kontinuierliche Arbeitskräfteerhebung für die Europäische Union
Authors: Van Bastelaer Aloïs
Published: September 2017

Statistiken zu Arbeitsmarkt und Beschäftigung sind im Hinblick auf mittelfristige Programme wie NAP, Agenda 2000 usw. von ebenso großer wie offenkundiger Bedeutung. Die jährliche Arbeitskräfte-Erhebung (AKE) ist in Österreich mit der EU-Mitgliedschaft 1995obligatorisch geworden, sie ist aber immer wieder inhaltlichen, z.T. auch methodischen Änderungen unterworfen. Durch Ratsverordnung (VO) vorgeschrieben, müssen die Erhebungen von den nationalen statistischen Ämtern durchgeführt werden. 1998 liegt dem Rat abermals eine neue Fassung der VO vor, die voraussichtlich für Erhebungen ab demBerichtsjahr 1998 Geltung haben wird. Diese - gravierende - Novellierung betrifft neben einigen inhaltlichen Revisionen v.a. die Einführung einer „kontinuierlichen“ Erhebung. Für Mitgliedstaaten, denen diese Änderung aus organisatorischen Gründen nicht (sofort) möglich ist, besteht aber weiterhin die Option, bei der bisherigen einmaligen Erhebung pro Jahr zu bleiben (dazu zählt auch Österreich).

Wählerstromanalyse der Nationalratswahl 1999
Authors: Neuwirth Erich
Published: September 2017

Die vorliegende statistische Wählerstromanalyse unterscheidet sich merkbar von der im ORF noch am Wahltag publizierten Analyse. Unterschiede sind insbesondere bei politisch relevanten Fragestellungen wie etwa der Größe des Wählerstroms zwischen der SPÖ und der ÖVP einerseits und der FPÖ andererseits festzustellen. Unsere Analyse wurde imGegensatz zur ORF-Analyse von einem wissenschaftlich ausgewiesenen Statistikererstellt. Zumindest aus wissenschaftlich-methodischer Sicht erscheint es daher sinnvoll, die im ORF publizierte Analyse nicht als alleinige Grundlage der Interpretation des Wahlergebnisses heranzuziehen.
Wirtschaftspolitik und Statistik
Authors: Kramer Helmut
Published: September 2017

Die Welt, in der die amtliche Statistik ihre Aufgaben wahrzunehmen hat, hat sich dramatisch verändert. Die strategische Position der amtlichen Statistik ist schwierig geworden: Die Umorientierung der Wirtschaftspolitik seit den sechziger Jahren hat dieBedeutung zentraler Ergebnisse der amtlichen Statistik (wie etwa der VolkswirtschaftlichenGesamtrechnung) für die heimischen Entscheidungsträger reduziert. Gleichzeitig erfordern die durch den Beitritt Österreichs zur Europäischen Union eingegangenen Verpflichtungen aber eine signifikante Leistungsausweitung der amtlichen Statistik. Der Widerstand der Respondenten wächst. Deregulierung und Liberalisierung erschweren in vielen Fällen dieArbeit der Statistik. Kennzeichen der neuen Wirtschaft wie neue Arten wirtschaftlicherAktivitäten, neue Formen von Beschäftigungsverhältnissen und Arbeitszeitregelungen sind mit traditionellen Instrumenten schwierig in den Griff zu bekommen.Ein erfolgreiches Bestehen der amtlichen Statistik in Österreich setzt voraus, daß die neue Führung bürokratische Hindernisse überwinden und eine Aufwertung der Tätigkeit der Anstalt – auch im Urteil der Öffentlichkeit – erreichen kann.
Zur Messung der Steuerbelastung von Unternehmen
Authors: Kostal Thomas
Published: September 2017

Zur Messung der (effektiven) Steuerbelastung von Unternehmen stehen mikroökonomische Methoden makroökonomischen Ansätzen auf Basis der VGR (implizite Steuerquoten) gegenüber. Beide Zugänge liefern Antworten auf unterschiedliche Fragestellungen, ihre Ergebnisse sind daher nicht vergleichbar. Während für die Berechnung mikroökonomischer (Grenz-) Steuerquoten eine akzeptierte Methode vorliegt, ist die Ermittlung impliziter Steuerquoten von Kapitaleinkommen problematisch undihre Interpretation schwierig. Als Indikator für die Steuerbelastung von Unternehmenseinkommen ist die ”einfache“ implizite Steuerquote kaum geeignet.Auf Basis der österreichischen VGR werden Bereinigungsmaßnahmen diskutiert, die eine Möglichkeit bieten, die tats¨achliche (durchschnittliche) Steuerbelastung der Einkünfte aus Unternehmertätigkeit zu ermitteln. Angesichts der derzeitigen Datenlage der offiziellen Statistik in Österreich erscheinen diese Bereinigungen jedoch nur mit Einschränkungen möglich.

Learning motivation and personal reflection in students: features and relationship
Authors: Tikhomirova T.S. , Kochetkov N.V.
Published: September 2017

The paper discusses the intensity of learning motivation in university students of various forms, stages and courses of education and its relationship with personal reflection. Large amounts of empirical data obtained in this research allow us to assert that the adequacy of learning motivation is higher in graduate students than in undergraduate students, the latter demonstrating the highest rates in their first year of study and the lowest in the third. Motivation rates in part-time undergraduate students tend to decrease during the first three years at university; however, the rates increase in the fourth year. We also compared learning motivation in respondents with different levels of reflective thinking. Asit was revealed, adequate motivation and motives for acquiring the profession were higher in students with high levels of reflection as compared to those displaying average and low levels. Moreover, the highest rates of reflection were found in students who planned to pursue their profession and knew exactly in which field, whereas the lowest rates were common for students who were not certain as to whether their work would correspond with their major discipline.
Psychologica lreadiness for management as a basis for potential competitiveness in prospective managers
Authors: Mitina O. , Nizovskikh N.A. , Sharafutdinova M.N.
Published: September 2017

The paper presents outcomes of a research on psychological readiness for management in students (future managers). Psychological readiness for management is understood as one’s general predisposition towards administrating himself/herself and other people that is based on the system of relevant values. The extent of manifestation of the components of psychological readiness is considered as the basis of potential competitiveness in university graduates.Our empirical research involved students majoring in management (n = 98) aged 18-23 years.The study revealed that management values are highly significant for the respondents and that there are gender differences in value hierarchies.The components of psychological readiness for management were found to be related with indicators of life satisfaction, time perspective and basic values in the students.The outcomes if this research may be applied in higher education, management and career counselling in schools and universities.
Model programmes of support for families raising ‘difficult’ orphan children
Authors: Oslon V.N.
Published: September 2017

The paper describes a system of organizational and technological measures that shape the principles, conditions, procedure, forms and methods of supporting families raising so-called ‘difficult’ orphan children, i.e. disabled children, adolescents, siblings. These children have specific needs when it comes to living in a family; their integration into the family takes much longer and is usually more complicated as compared to other orphans. It is not uncommon for families to be afraid of such children and to refuse taking care of them. Still, the key factor of successful family integration of these children is a special system of support. Model programmes that were developed in 2016 at the request of the Ministry of Education and Science of the Russian Federation can well be considered as methodological and procedural guidelines for the emerging system of support for families taking care of orphans with special family needs as well as for specialist training courses.

In the present work a molecular genetic analysis of the receptor part of the nfr5 gene in 15 plants of the conjugate collection (the plant component Melilotus albus, the bacterial component Sinorhizobium meliloti) has been done. Was studied the LysM domains structure and found a high level of the nucleotide polymorphism in LysM domains of this gene. A clear relationship of nucleotide and amino acid polymorphism in the receptor region of the nfr5 gene with the genetic diversity of the rhizobial component (bacterial symbiotic locus nodD) was observed. Based on these data, the computer modeling of binding of the bacterial Nod-factor with two different variants of the plant receptor was performed.

Using ethylmethansulphonate the chemical mutagenesis of the pea laboratory line SGE was performed. During analysis of 425 families (2069 plants) of Мsub2/sub progeny 45 putative mutants were selected, among them 30 mutants forming ineffective nodules (Fixsup–/sup phenotype), 13 mutantsunable to form nodules (Nodsup–/sup phenotype), and 2 mutants forming a few nodules (Nodsup+/–/sup phenotype). For 1 Nodsup–/sup and 5 Fixsup–/sup mutants monogenic inheritance and recessive phenotype manifestation were demonstrated. For Fixsup– /supmutant SGEFixsup–/sup–9 an additional mutation leading to Nodsup+/–/sup phenotype was shown. Complementation analysis showed that the mutant phenotype of the SGEFixspan style="font-size:11px"sup-/sup - /span5 line is caused by a mutation in the sym33 gene, of theSGEFixsup–/sup–6 linein the sym40 gene, of the SGEFixsup–/sup–7 line in the sym27 gene, and of the SGEFixsup–/sup–8 linein the sym25 gene.

Published: September 2017

The quantity of antibody producing cells and mitotic disturbances in dividing bone marrow cells of mice were studied after exposure of animals to a physical stressor or various pyrazinecontaining chemosignals. Several different strains of mice were used. We demonstrate that immune suppression and destabilization of the chromosome apparatus in dividing cells depend on: а) mouse genotype and b) side chains position  in the pyrazine ring. Importance of this effects in the light of wide usage of pyrazine containing substances in perfume industry, food production and pharmacology is discussed.

Published: September 2017

The new taxonomic marker (hin-region) has been proposed, which gives possibility for Rhizobium bacteria study on “species — group of strains” level. Using this marker the groups of Rhizobium strains were determined, which could not be distinguished with other methods, and these results correlated with evolutionary similarity of the bacteria. The developed approach for creating marker systems allows to carry out effective inventory of inter- and intraspecies genetic diversity of nodulating bacteria and to evaluate perspectives of their use in agriculture. The proposed marker system was used for description of Rhizobium bacteria samples isolated from various ecological-geographical regions of Ukraine.

Published: September 2017

The chromosome aberration test in bone marrow cells of mice was used to study the influence of valocordin on spontaneous and induced clastogenesis. Valocordin showed no inherent clastogenic activity. In experiments with pretreatment and with single or repeated combined administration , valocordin in doses of 0.03, 0.3 and 3 ml/kg significantly (47–133 %) enhanced the clastogenic activity of cyclophosphamide. There was no effect of valocordin on the cytogenetic activity of dioxidine, a mutagen with a pro-oxidative mode of action. Possible mechanisms of comutagenic activity of valocordin are discussed.

Published: September 2017

Using pea single mutant lines SGEFix–-2 (sym33) and RisFixV (sym42), which are characterized by different abnormalities during symbiotic nodule development, including thickening of infection threads’ walls, a double mutant RBT4 line, carrying a pair of symbiotic genes sym33 and sym42 was constructed. The epistasis of the mutant allele sym33 over the mutant allele sym42 with respect to the histological and ultrastructural organisation of nodules was shown. Thus, it was demonstrated that Sym33 gene functions earlier in symbiotic nodule development than Sym42 gene.
CRISIS OF THE TRADITIONAL VARIABILITY CONCEPT: ON THE WAY TO A NEW PARADIGM
Authors: Tikhodeyev Oleg N
Published: September 2017

The traditional concept of variability meets a lot of contradictions. These contradictions could be successfully overcome, when such variability aspects as a molecular nature of varieties, their heritability, and the factors directly determining organism phenotype, are clearly distinguished. The partition between hereditary and non-hereditary variability also needs correction since multiple intermediate phenomena are known. A more detailed classification is suggested, which reflects three autonomous aspects of heritability. This approach could be used as a basis for a new paradigm in the notion of variability.
Reproductive characteristics of mouse males are influenced by the mouse female pheromone 2,5-dimethylpyrazine in the C57BL/6 strain
Authors: Daev Eugene V , Dukelskaya Anna V
Published: September 2017

The influence of the mouse female pheromone 2,5-dimethylpyrazine was studied on significant reproductive characteristics in C57BL/6 males. With this purpose the frequency of pheromonally induced sperm head abnormalities and dominant lethal frequency was analyzed. It is shown, that the level of different sperm head abnormalities increases significantly after exposure with the pheromones. Simultaneously with it the frequency of dominant lethals elevates significantly in the progeny of the treated males. Connection of the revealed effects with the destabilizing influence of the pheromone on the genome of dividing germ and somatic cells at laboratory mice is discussed
Photoperiodic regulation of reproductive and hormonal rhythms, and litter size in silver foxes (Vulpes vulpes): effects of selection for domestic behavior
Authors: Osadchuk Ludmila V
Published: September 2017

The silver fox is a strictly seasonal breeder, and photoperiod is the primary environmental cue that regulates reproduction in this species. The aim of the present paper is to study effects of long-term selection of silver foxes for domestic behaviour on photosensitivity in respect of oestrus activity, ovarian hormonal function and the litter size. Adult silver fox females from the commercial and selected population were exposed to artificial photoperiods (9.5L: 14.5D) from September until March in a specially equipped shed. The females of two behaviour types maintained in natural daylight served as a control. The experimental groups received illumination in two fractions, one of 7 and one of 2.5 hours duration. The 7-hour period was natural daylight from 10:00 to 17:00 and the additional light pulse was artificial illumination at night (00-02:30), in the morning (06:00-08:30) and in the evening (17:30-20:00). The results demonstrate that a light pulse at night can induce early oestrus and ovarian hormonal activity in anoestrus fox females and the effect was expressed in most extent in selected than in control females. Additionally, this photoperiod decreased dramatically the litter size in both behavioural groups. Photoperiods with morning and evening additional light pulse did not change the temporal pattern of the reproductive rhythm but the litter size was also decreased in control-combined group but not in selected one. All artificial photoperiods depressed the ovarian hormonal activity during follicular and luteal phases of the ovarian cycle and the group with the night additional light pulse had a most pronounced response. The data obtained suggested that behavior selection resulted in an alteration in the relationship between the endogenous reproductive rhythm and environmental photoperiod and increased resist-ibility to detrimental effects of artificial photoperiods on the litter size
Tendril-less2 (TI2) - a gene providing the pea Pisum sativum L with ability to climb
Authors: Berdnikov Vladimir A , Gorel Faina L
Published: September 2017

After gamma-ray treatment of pea seeds, a mutation tendril-less2 (tl2) was obtained. In heterozygote, it transforms tendrils into a narrow leaflets, resembling an action of the classic mutation tl. In contrast to tl, the novel mutation, when homozygous, does not affect leaf development but supresses pigmentation of petals. It is suggested that both genes (Tl and TI2), responsible for transformation of leaves into an organ of climbing, have common origin from a gene controlling anthocyanine synthesis

Authors: Vostrukhina Olga A , Shtam Tatyana A , Mokhova N V , Gulyaev Aleksey V , Chepick Oleg F , Lanzov Vladislav A
Published: September 2017

The human carcinomas of gastrointestinal tract (GIT) are developed via "suppressor" (pJJ-dependent) or "mutator" (with deficiency in DNA mismatch repair) pathways. These pathways are known to be accompanies by variations in both clinicopathological and therapeutic characteristics. The mutator pathway manifests in genome microsatellite instability (MSI). All GIT carcinomas can be subdivided in three classes, with high (MSI-H), low (MSI-L) and zero (MSS) level of MSI. 34 DNA samples from GIT carcinomas were analyzed with 9 microsatellites and 5 exones of p53 gene in searching for correlation between the level of MSI and mutations inp53. The MSI-H carcinomas appeared to be of mutator type whereas both MSI-L and MSS were of suppressor type
