Electric Field Gradient at Nb Site in the Intermetallic Compounds Nb3X (X = AI, In, Si, Ge, Sn) Measured by PAC
Authors: Junqueira A. C. , Carbonari A. W. , Filho J. Mestnik , Saxena R. N.
Published: September 2020

The electric field gradient (efg) at the Nb site in the intermetallic compounds Nb3X (X = Al, In, Si, Ge, Sn) was measured by the Perturbed Angular Correlation (PAC) method using the well-known gamma-gamma cascade of 133 -482 keV in 181Ta from the β- decay of 181Hf, substituting approximately 0.1 atom percent of Nb. The PAC results show that Vzz drops by nearly 40% when X changes from Al to In, and by about 25% when X changes from Si to Ge and Sn. This behavior is most probably related to the change in the degree of sp hybridization in these compounds. The Vzz values of the studied compounds do not follow the well known universal correlation for the efg's in non-cubic metals but the observed trend is well reproduced by results of ab-initio electronic structure calculations. In the case of Nb3 Al a linear temperature dependence of the quadrupole frequencies was observed in the temperature range of 6.5 to 1210 K.

The crystal structure of [C(NH2)3]HgBr3 was determined at room temperature: monoclinic, space group C2/c, Z = 4, a = 775.0(2), b = 1564.6(2), c = 772.7(2) pm, β = 109.12(2)°. In the crystal, almost planar HgBr3- ions are connected via Hg ··· Br bonds, resulting in single chains of trigonal bipyramidal HgBr5 units which run along the c direction. [C(NH2)3]HgI3 was found to be isomorphous with the bromide at room temperature. The temperature dependence of the halogen NQR frequencies (77 < 77K < ca. 380) and the DTA measurements evidenced no phase transition for the bromide, but a second-order phase transition at (251 ± 1) K (Tc1) and a first-order one at (210 ± 1) K for the iodide. The transitions at Tc2
are accompanied with strong supercooling and significant superheating. The room temperature phase (RTP) and the intermediate temperature phase (ITP) of the iodide are characterized by two 127I(m=1/2↔3/2) NQR lines which are assigned to the terminal and the bridging I atoms, respectively. There exist three lines in the lowest temperature phase (LTP), indicating that the resonance line of the bridging atom splits into two. The signal intensities of the 127I(m =1/2↔3/2) NQR lines in the LTP decrease with decreasing temperature resulting in no detection below ca. 100 K. The 127I(m=1/2↔3/2) NQR frequency vs. temperature curves are continuous at Tcl, but they are unusual in the LTP. The T1
vs. Tcurves of 1H NMR for the bromide and iodide are explainable by the reorientational motions of the cations about their pseudo three-fold axes. The estimated activation energies of the motions are 35.0 kJ/mol for the bromide, and 24.1, 30.1, and 23.0 kJ/mol for the RTP, FTP, and LTP of the iodide, respectively

Published: September 2020

Emerging data supports a potential role of neurotensin (NT) in the development of obesity, obesity-associated comorbidities, and certain cancers. The association of NT with colon cancer risk has not been explicitly explored. We determined plasma levels of pro-NT, a stable NT precursor fragment, in 223 incident colon cancer patients and 223 age-, gender-, BMI-matched population controls participating in a population-based case–control study of colon cancer. On average, the cases have significantly higher levels of pro-NT than the controls (median = 205.6 pmol/L vs 183.1 pmol/L, respectively; P = 0.02). Multivariate logistic regression models, adjusted for age, gender, BMI, family history of colorectal cancer, smoking, diabetes mellitus, alcohol, and non-steroidal anti-inflammatory drugs use, show statistically significant risk associations: for continuous measure of pro-NT, the OR estimate was 1.30 (95% CI =1.03–1.64; P = 0.026) for each increment of 175 pmol/L; for dichotomized measure of pro-NT, the OR estimate was 1.75 (95% CI = 1.12–2.74; P = 0.025) for those in the top quartile comparing to the other participants. Our results support circulating levels of pro-NT as a novel risk biomarker for colon cancer.
Bonding between cellulosic fibers in the absence and presence of dry-strength agents – A review
Authors: Hubbe Martin
Published: September 2020

Various hydrophilic polyelectrolytes, including cationic starch products, are used by papermakers to promote inter-fiber bonding and increase paper’s dry-strength. Thus, papermakers can meet customer requirements with a lower net cost of materials, more recycled fibers, or higher mineral content. In the absence of polymeric additives, key mechanisms governing bond development between cellulosic fibers include capillary action, three-dimensional mixing of macromolecules on facing surfaces, conformability of the materials, and hydrogen bonding. Dry-strength additives need to adsorb efficiently onto fibers, have a hydrophilic character, and have a sufficiently high molecular mass. Though it is possible to achieve significant strength gains by optimal usage of individual polyelectrolytes, greater strength gains can be achieved by sequential addition of oppositely charged polyelectrolytes. Superior strength can be achieved by in-situ formation of polyelectrolyte complexes, followed by deposition of those complexes onto fiber surfaces. Polyampholytes also hold promise as efficient dry-strength additives. Opportunities for further increases in performance of dry-strength agents may involve fiber surface modification, self-assembled layers, and optimization of the dry film characteristics of dry-strength polymers or systems of polymers.
PENSIJŲ SISTEMOS TVARUMAS IR JOS DALYVIŲ INTERESAI
Authors: Azguridienė Guoda
Published: September 2020

Straipsnis skirtas pensijų reformų temai, tačiau ne įvairiems reformų modeliams analizuoti, o pačios reformos būtinumui pagrįsti. Daugiausia dė­mesio teikiama skirtingiems ir prieštaringiems pensijų sistemų dalyvių inte­resams. Straipsnyje teigiama, kad reformuoti pensijų sistemą reiškia pakeisti jos dalyvių interesus iš antagonistinių – kokie jie yra PAYGarchitektūroje – į kooperacinius. Kooperaciniai santykiai – asmeninių santykių, bendruomenių ar verslo forma – gali skleistis tik laisvesnėje, lankstesnėje ir mažiau politiš­kai paveikioje socialinės apsaugos sistemoje. Daroma išvada, kad priešingu atveju jokiomis ekonominėmis bei politinėmis priemonėmis nepavyks iš­vengti vidinės sistemos įtampos ir pasiekti ilgalaikį pensijų sistemos tvarumą bei socialinę vertę.

Straipsnyje analizuojama Didžiosios strategijos raida istorijoje ir nacionalinių valstybių didžiųjų strategijų perspektyvos šiuolaikiniame pasaulyje. Nagrinėjama valstybių, turinčių Didžiąją strategiją, patirtis, tokios strategijos poreikio ir paskirties XXI a. problema. Teigiama, kad globaliame pasaulyje nesumenkėjo nacionalinės Didžiosios strategijos reikšmė ir poreikis – pakito tik jos įgyvendinimo aplinka ir sąlygos. XXI a. Didžiojoje strategijoje valstybės „įsitvirtinimo po saule“ sąvoką keičia „įsitinklinimo“koncepcija, kuri reiškia valstybės pastangą išnaudoti globalizacijos teikiamas galimybes nacionalinės plėtros tikslais. Vakarų pasaulio valstybės nėra natūraliai „pasmerktos“ didėjančios gerovės, kylančios kokybės ir sanglaudos vizijos išsipildymui. Vakarietiškosios Didžiosios strategijos, paremtos liberaliosios demokratijos koncepcija, modelio plėtros sėkmė priklausys ne tik nuo globalizacijos jėgų logikos, bet ir nuo sprendimų, kuriuos privalės priimti valstybių vyriausybės. Tai gali aktualinti nacionalinių didžiųjų strategijų poreikį.

Neocatolicismo, carlismo y democracia
Authors: González-Cuevas Pedro-Carlos
Published: September 2020

En España, el liberalismo triunfó de forma temprana sin conseguir un amplio nivel de legitimidad social; lo que igualmente obstaculizó el advenimiento del sistema político demoliberal. A lo largo del siglo XIX, la rebeldía antiliberal se centró en el carlismo. Sin em-bargo, en sus comienzos el carlismo careció de una doctrina política específica. Fueron los neocatólicos, herederos de los planteamientos de Jaime Balmes y Juan Donoso Cortés, quienes consiguieron articular y vulgarizar un proyecto político tradicionalista, que tendría su mayor desarrollo frente a la revolución democrática triunfante en septiembre de 1868. Un proyecto político que tendría su renovación en el siglo XX español.
Las elecciones democráticas a Cortes Constituyentes de 1869
Authors: de-la-Fuente-Monge Gregorio
Published: September 2020

Las elecciones generales a Cortes Constituyentes de enero de 1869 son las primeras celebradas en España por sufragio universal masculino directo. Utilizando las actas de las Juntas electorales como fuente histórica, y con una metodología diferente a la que en su día utilizó Martínez Cuadrado, se analizan los resultados en todas las circunscripciones electorales y en el conjunto de España, así como la composición política de las Cortes salidas de la revolución de 1868. Estas elecciones fueron muy competitivas y registraron la mayor participación del Sexenio Democrático. La coalición monárquica liberal, que respaldaba al Gobierno Serrano-Prim, obtuvo una amplísima victoria sobre los republicanos y los monárquico-católicos, impulsando como mayoría parlamentaria la Constitución democrática de 1869. El estudio de la participación electoral y del apoyo ciudadano a los partidos se fundamenta en datos homogéneos. Como investigación básica sobre los resultados electorales, puede servir para elaborar nuevas comparaciones e hipótesis de trabajo.

Authors: Lima Waléria Paixão de , Lima Camila Astolphi , Santos Renato Barbosa dos , Soares Wuber Jefferson de Souza , Perracini Monica Rodrigues
Published: September 2020

Abstract Objective : to investigate the association between utilitarian walking and walking as exercise, and socio-demographic, clinical and functional covariates related to these walking types. Methods : a cross-sectional exploratory study was conducted with 148 older adults (aged 60 and over). Walking frequency and duration was assessed using the IPEQ-W (Incidental and Planned Exercise Questionnaire - Version W). Socio-demographic, clinical conditions, level of disability and mobility were also assessed. Types of walking were compared among the variables using the Mann-Whitney test and non-parametric Spearman rho correlations were used to investigate the association between the types of walking and the variables. Results : the participants performed a mean of 1.1 (±2.1) h/week of walking as exercise and 2.2 (±2.3) h/week of utilitarian walking. Older adults who had diabetes (p=0.015) did fewer h/week of walking as exercise. Participants who were older (p=0.014), reported poor self-rated health (p<0.001), poor disability levels (p<0.001), hypertension (p=0.048), strokes (p<0.001), heart disease (p=0.026), urinary incontinence (p<0.001), dizziness (p=0.008), or sleep disorders (p=0.042) spent fewer hours performing utilitarian walking. Correlations between the covariates and types of walking varied from very weak to weak. Conclusion : chronic diseases and unfavorable health conditions decreased walking time. Utilitarian walking was the most frequent type of walking performed by the older adults. Health care professionals and public policy managers should use utilitarian walking as a way of increasing levels of physical activity and to promote healthy aging.

ABSTRACT The knowledge of the prevalence of bovine cysticercosis is important for the implementation of control programs. The objective was to evaluate the prevalence and geographical distribution of bovine cysticercosis in Northern Minas Gerais. For that, 14,556 cattle were evaluated during the federal post-mortem inspection in 27 municipalities of five microregions: Janaúba, Montes Claros, Januária, Pirapora and Bocaiúva. The prevalence of Cysticercus bovis was 1.03% with distribution in all microregions evaluated of the northern Minas Gerais. All municipalities with a sampling number of cattle slaughtered above 543 showed positive animals for cysticercosis. The microregions of Bocaiúva, Montes Claros, Janaúba, Januária and Pirapora presented a prevalence of cysticercosis at 2.11%, 1.17%, 1.01%, 0.90% and 0.56%, respectively. The microregions of Montes Claros and Januária presented a greater chance of finding positive cattle for cysticercosis. As there are positive cases of cysticercosis in all microregions evaluated, there is a risk to human health.

Authors: Nair Sukanya J. , Sasikumar Kizhakkayil
Published: September 2020

A large number of multi-reservoir hydropower systems are in operation all over the world in order to meet increasing power demand. To date, different optimisation methods have been applied to multi-reservoir systems. However, overcoming the computational effort required to find an optimal operating policy for multi-reservoir systems still remains a difficult task. The aim of this study was to optimise the operation of complex multi-reservoir hydropower systems using profust reliability – a theory used in the reliability analysis of manufactured systems. The profust-reliability-based optimisation model was applied to a system with reservoirs connected in series and parallel to determine monthly operating policies for synthetically generated streamflow. The results show that the model is applicable to multi-reservoir systems.

Published: September 2020

Paraffin sections (4 μm thickness) of formalin-fixed human pancreases and isolated human islets were treated with 0.05% pronase for antigen retrieval. HS and Col18 HSPG core proteins were detected immunohistochemically using 10E4 anti-HS (US Biological/Amsbio) and anti-Col18 (Santa Cruz), respectively, with horseradish peroxidase-conjugated rabbit anti-mouse Ig (Dako). Background staining was checked using the corresponding isotype control Ig instead of the primary antibody. 3-amino-9-ethylcarbazole (AEC) was used as the chromogen. For morphometry, stained sections were imaged using a light microscope with attached camera (Olympus BX41). Image J software with color deconvolution plugin was used for the quantitative analysis of the % of islet area stained

The features of the formation of communicative competence in the classroom are described in detail with a personality-oriented approach in the process of learning the Russian language as a foreign language. In the educational process with foreign students, a special place is occupied by professionally oriented reading. The methodology of teaching Russian as a foreign language presents different types of reading. The methods of studying, familiarization and viewing types of reading are described in detail, which are relevant in the study of Russian as a foreign language. In the process of formation and development of the communicative competence of foreign students, attention should be paid to the learning objectives, the content of the educational material, to focus on the professional motivation of students needed to develop communication skills and abilities, to communicate with teachers of special disciplines. The teacher should take into account that when teaching a language, it is important to include such approaches to modern students in the educational process in order to obtain high-quality results that they could subsequently use in their professional activities. The paper notes the need to choose professionally-oriented textual material for reading, which is so necessary for foreign students. According to the authors of the article, professionally oriented reading is both a goal and a means of teaching Russian to foreign students, as well as the need to familiarize students with the original literature in the specialty in order to successfully apply the knowledge and skills acquired in the Russian language classes in the educational process.

The paper considers one of the most important technologies in teaching Russian as a foreign language - interactive learning. The use of this technology helps to increase the effectiveness of training and the development of students' motivation, as it is aimed at realizing the main goal, which is to enhance speaking competence, using dialogue forms of communication in each lesson. The paper describes examples of interactive learning technologies that can be used when teaching Russian as a foreign language. However, the authors of the paper believe that it is not possible to make the process fully interactive in the modern context due to the lack of both technical equipment and a complete educational and methodological complex. The authors see a partial solution to this problem in the creation and further use of authentic materials. This didactic technique allows you to increase interest in the subject under study, to form and develop both linguoculturological and communicative competencies. This paper presents an authentic set of interactive teaching tasks developed by the authors for the Russian as a foreign language lesson. The lesson plan is shown, and the results of introducing the technology are described using the example of separate exercises. Having implemented the lesson plan, the authors have come to certain conclusions. So, for example, based on the active participation of students and the interest shown in the topic of the lesson, the authors believe that the language material was chosen successfully. The motivation of students plays a vital role in the acquiring of educational material, and therefore in the development of communicative competence.
CASE STUDY in the system of a professionally-oriented foreign language teaching at higher school
Authors: Igumnova Olga V.
Published: September 2020

Foreign language at higher school reflects the specific of the students’ forthcoming professional activity. Decade-old publications prove the need of including case study in a foreign language teaching, the stages of working with the case are revealed. However, the case study method will promote the language teaching effectiveness, if a student is ready to work with cases. The purpose of this paper is to indicate the possible consistency of the methods of teaching a professionally-oriented foreign language at junior courses of non-linguistic universities, as well as the place of the case study in them from the point of view of the effectiveness of its application. When writing the paper, such theoretical research methods as analysis, synthesis, systematization, generalization, abstraction, design and modeling of the educational process as well as case study application evaluation criteria were used. Such an approach to the generalization of private teaching experience makes it possible to identify pedagogical conditions of case study application efficiency in teaching and learning activities, to specify the strategic and tactical language learning process design with cases in mind and to present the modeling of teaching within one topic. The author agrees that the case study allows assessing the students’ level of foreign language competence formation. At the same time, it is noted that the case study application evaluation should consist of components that track the overall curricular actions of the language trainer from the beginning to the completion of the study of the topic. In this regard, it is necessary to evaluate the quality of the case analysis completed by students, the availability, logic, consistency and literacy of their statement of the case issues, as well as the ability to operate the actual material studied within the topic, students’ readiness for dialogue and the use of compensatory skills to realize their own communicative intention. The proposed criteria and stages of modeling teaching and learning activities can be used in practice.

Evacuation characteristics of pedestrians can be captured under two different conditions - one in immediate and another in non-immediate. The safe and quick evacuation of pedestrians from a building in any situation depends on pedestrian and building characteristics. Understanding the behaviour of pedestrians in emergency situations such as earthquake or fire accident helps in designing buildings for safe evacuation. In view of the limited research on this problem in the Indian subcontinent, this study aims to capture the pedestrian flow characteristics in emergency situations by conducting several experiments in a classroom environment. As a part of the experimental study, the students were instructed to behave as if they were in an emergency evacuation situation. Data was collected on pedestrians with different age profiles such as high school, under graduate and post graduate students considering various scenarios that includes different door widths. Several factors such as number of pedestrians, width of the door, average age of the pedestrians, Body Mass Index, proportion of females, number of students and classroom capacity are considered and their influence on evacuation characteristics was analysed. Based on the observations, an evacuation model has been developed using least square error method. Results show that the variables such as door width and number of students are crucial in representing evacuation time of the classroom. It was found that the relationship between total evacuation time (TET) and door width is represented by power function. This is contrast to the findings of existing literature which shows that the relationship between flow and door width is linear. Our results are best supported by the fact that the TET is exponentially varying with door width till a particular value and remains constant for further increase in door width which is realistic in nature. It is anticipated that the results of the study would provide guidelines to various agencies on managing evacuations. This can also lead to suggestions on optimization of layouts while designing various building access facilities in an academic environment.

Published: September 2020

There is, as you know, a method of supravaginal amputation of the uterus, according to which the stump formed by the remaining uterine cervix is not sheathed by the peritoneum, but simply captured only in the ligature; while, according to H. Treub'u, the ligature is applied only around the neck, en masse, according to the method practiced by prof. DO Ottom, ligatures, number from 2 to 4, pass through the thickness of the uterine wall, without capturing the cervical canal and thus leaving it passable.

Published: September 2020

El artículo expone los resultados de la investigación llevada a cabo para conocer los efectos sociopedagógicos y políticos derivados de la interacción entre la competencia changemaker y la autonomía de centro, abriendo una discusión sobre sus posibilidades y límites. Se parte del análisis de los argumentos que establecen una relación entre: a) el cambio competencial experimentado en el ámbito educativo para que los ciudadanos sean capaces de desenvolverse de forma satisfactoria y b) la autonomía de centro como rasgo organizativo catalizador de su implementación. Revisada la teoría de su interacción positiva, se comprueban sus efectos prácticos a través del análisis cualitativo de tres Proyectos Educativos de Centro de la Comunidad Autónoma de Castilla y León. En los proyectos se han desarrollado innovaciones relacionadas con la acción y el cambio social, implementando metodologías de Aprendizaje Servicio y de Comunidad de Aprendizaje y Enseñanza Democrática. Se identifican como categorías de análisis, la innovación, las competencias, la planificación de las actuaciones, los responsables y la evaluación. Los resultados muestran como la autonomía de centro, si bien de modo diferencial, permite en la práctica configurar los procesos de aprendizaje y la adquisición de la competencia global Changemaker.
La autoeducación permanente en un contexto sociotécnico
Authors: Vázquez Gómez Gonzalo
Published: September 2020

La educación permanente es un proceso de autoconstrucción basado en los principios pedagógicos de la educabilidad, la educatividad y la autonomía personal. El proceso de construcción humana implica un proceso de aprendizaje y de formación a lo largo y ancho de la vida a fin de conseguir el “bienestar” (la vida buena) individual y comunitario. Esta concepción de la educación permanente incluye la consideración de nuevos espacios de aprendizaje como el de la ciudad cognitiva y nuevas posibilidades como la constituida por la existencia de los cursos abiertos. Dentro del enfoque de la formación de las capacidades se estudian las posibilidades y riesgos del aprendizaje autorregulado como una estrategia eficaz en el actual contexto socio-técnico y de globalización tecnológica. Finalmente, se examina el potencial de riesgo que supone la aportación de la analítica del aprendizaje y de la inteligencia artificial (IA) a la educación para cuya superación se reclama que el proceso de educación permanente esté basado en una sólida formación humana.
Culpa de la víctima como eximente de responsabilidad
Authors: Carrera Torres Paúl Ricardo , Roldán Carrillo Felipe Nicolás , Vera Saltos María Alejandra
Published: September 2020

Al pasar de los años, el sistema de la responsabilidad civil, en general, se concibió con la finalidad de que la víctima sea indemnizada por los daños sufridos. Sin embargo, en el régimen de la responsabilidad civil extracontractual, existen situaciones en las que la víctima participa activamente en la producción de su propio daño. Frente a esto, se ha pretendido dilucidar si la llamada culpa de la víctima responde a la hipótesis de concurrencia de culpas o culpa exclusiva de la víctima, tomando en cuenta dos de los elementos que rigen el Derecho de Daños: culpabilidad y causalidad.

Published: September 2020

La presente investigación analiza la figura de los smart contracts o contratos inteligentes, los cuales se caracterizan por su ejecución automática a través de blockchain. Se desmiente la creencia de que por ejecutarse automáticamente, estos contratos están exentos de disputas, y se analiza qué tipo de controversias podrían surgir de ellos. El presente trabajo sostiene que el arbitraje posee ciertas características, en particular su deslocalización, flexibilidad y confidencialidad, que lo convierten en el método idóneo para resolver disputas derivadas de smart contracts, y analiza cómo dos plataformas han desarrollado mecanismos de resolución de disputas para contratos inteligentes. A la luz del procedimiento adoptado por estas plataformas y de la Teoría General del Arbitraje, se hace un análisis de los desafíos que implica arbitrar este tipo de contratos.
Impact of Electric Power Pricing Reforms on the Japan’s Industry and Household Sector
Authors: Jung Woojong
Published: September 2020

After the Fukushima nuclear power plant accident, Japan had an opportunity to advance its economic and energy policies to pursue stable energy supply, economic efficiency, environmental security, and safety. The accident not only raised concerns regarding the safety of nuclear power plants but also increased awareness regarding the effect of energy import growth on the economy and related issues such as the effect of imports on Japan’s international competitiveness. This study simulates the impact on electricity prices using three potential scenarios for Japan. According to the results, the consumer price index (CPI) was larger than the corporate goods price index (CGPI) for Japan in all cases. In the simulation results, the CPI was observed to have an increased effect of 0.88%–3.59% against a 0.84%–3.41% increase in the CGPI. The surge in electricity prices significantly impacted the supply of electricity, gas, and heating and also the business services sector. The cost of policies that maintain safety, the increase in costs resulting from the overseas importation of fossil fuels, and the cost of promoting renewable energy in conjunction with the reutilization of nuclear power plants leading to higher electricity prices will also be considered in the future.
