Published: February 2020

Menegua es la primera variedad de algodón específicamente para suelos ácidos en Colombia con recomendación, además de incluir en el sistema de rotación maíz-soya, como estrategia para ampliar la frontera algodonera en la subregión ‘altillanura plana’. No obstante, su manejo agronómico en relación con la distancia de siembra requiere de un ajuste como una estrategia para mejorar la competitividad del algodón en términos de rendimiento, calidad y costos. El objetivo de este estudio fue determinar el efecto del surco ultra-estrecho en comparación con el convencional en el desempeño productivo y calidad del algodón en condiciones de un suelo ácido oxisol en la altillanura plana colombiana. Se realizó un experimento en Puerto Gaitán-Meta, durante el ciclo agrícola 2015B, se usó un diseño de bloques completos al azar con dos tratamientos correspondientes a distancias entre surcos en cm): T1= 0.4 y T2= 0.8 y cuatro repeticiones; se utilizó la variedad Menegua con adaptación específica para suelos ácidos y se determinaron variables productivas y de calidad de fibra. El cambio de la distancia convencional de 80 cm a 40 cm ocasionó incremento de 13.1% en la altura de la planta, reducción 29.2% en el número de motas planta-1 y disminución 23.1% y 23.9% en el rendimiento de algodón semilla y rendimiento de algodón fibra, respectivamente, el porcentaje de extracción de fibra y su calidad no fue afectada. Se concluye que en la subregión ‘altillanura plana’ en un suelo ácido oxisol el surco ultra estrecho en comparación con el convencional afecto la variedad Menegua de manera negativa el comportamiento productivo sin detrimento de la calidad de la fibra en el algodón.

Authors: Maldonado-Torres Ranferi , Álvarez-Sánchez Ma. Edna , Abarca-Cervantes Alma Delia , Vargas Gustavo Almaguer
Published: February 2020

La deficiencia de calcio origina susceptibilidad a enfermedades fisiológicas en frutos y reducción de rendimiento, además de generar enroscamiento, clorosis y disminución en el crecimiento de hojas jóvenes. En el presente trabajo fue realizado en el año 2017, donde se obtuvieron medidas estructurales y ultraestructurales celulares de hojas de aguacate, mediante un microscopio electrónico de barrido y transmisión respectivamente y se correlacionaron con la concentración nutrimental foliar. Se observó que el grosor de la hoja, el largo del parénquima esponjoso más epidermis y el largo y ancho de parénquima en empalizado no tuvieron afectación significativa con la concentración de calcio solo, pero sí con las relaciones nutrimentales: BxCa, KxCa, ZnxCa, Mn/Ca y Ca/Mn. El ancho de la pared celular fue afectado por las relaciones con magnesio: Mn/Ca y Ca/Mn.

Published: February 2020

People assume that cancer is a deadly disease. The communication gap between doctor and their patients results in incomplete information obtained by people with cancer. This research was conducted using a qualitative approach in order to explore the meaning of cancer for cancer sufferers in Bandung Cancer Society. Theories used as references are phenomenology and symbolic interactionism. The results of the study of 10 informants indicated that cancer is a very frightening disease; cannot be cured and there is no life expectancy; cancer is caused by unhealthy life style; and yet cancer increases acts of worship. All informants as cancer survivors made efforts to survive by following the doctor's advice. Another result of this study states that communication that takes place between cancer survivors and other fellow sufferers in Bandung Cancer Society can  change the view of cancer, motivate and raise the spirit of life.
Los Grupos de Innovación Educativa GIE: Una alternativa válida para los Docentes Universitarios
Authors: Pesántez Avilés Lauro Fernando
Published: February 2020

Las Instituciones de Educación Superior de América Latina no necesariamente han manejado un escenario de vanguardia en los procesos de la investigación científica, sea porque su tradición académica estuvo orientada, especialmente, al ámbito de la docencia o, porque se ha subestimado el potencial de sus claustros académicos para generar conocimiento o, incluso, por las precarias fuentes de financiamiento que han soportado los proyectos universitarios, por lo que, históricamente, se ha privilegiado la enseñanza y la extensión sobre la investigación.

Sin embargo, de lo antes mencionado, no deja de ser verdad que, en más de una ocasión, los cuerpos docentes, muchas veces en solitario y con insuficientes estructuras de gestión universitaria, han solventado soluciones pertinentes a los desafíos que su entorno sociocultural les ha sabido requerir a título de la función investigación. Ante la dualidad presente, es necesario desmitificar aquellas lógicas que privilegian la visión de que la investigación solo puede ser gestada por aquellos con grandes dotes disciplinares o que es particular proceso de los que poseen un grado científico del más alto nivel.

Hacia una Teoría del Riesgo Humanístico en la Responsabilidad Social de Garantías Recíprocas desde la Complejidad
Authors: Camacho Quintero Carlos Liborio
Published: February 2020

El objetivo del artículo es generar una teoría humanista basada en la responsabilidad social, con la finalidad de indagar las garantías reciprocas en tiempos complejos, ontológicamente el ser y el hacer como proceso integral, examinando el efecto del otorgamiento de la fianza sobre el riesgo de la sociedad. Actualmente el sistema nacional de garantías muestra principios axiológicos en la cultura de riesgo del ser humano. En las instituciones financieras la ambigüedad y entropía genera baja liquidez exponiendo altos niveles de incertidumbre lo que hace que el apalancamiento sea ineficiente. Metodológicamente se empleará el paradigma cualitativo de tipo fenomenológico, tomando en consideración a los informantes clave el cual estará conformado por cuatro (04) gerentes o propietarios de Pequeñas Y Medianas Empresas (PYMES), ubicadas en el Municipio Libertador y Campo Elías. Este ambiente inestable hace al sistema financiero sensible a la hiperinflación por los altos costos ya que no existe una competencia perfecta en la economía, asimismo, el exiguo crecimiento cambiario por su complejidad es detonante para las instituciones en las cuales afecta tanto micro como macroeconómicamente la ventaja competitiva sustentable y sostenible.

On improved RCM model to theart evaluation for radiation sesource
Authors: Zhang Ying , Wang Wei Hong , Xiang Fan Yu , Guo X.T.
Published: February 2020

Focusing on the deficiency of intuition, real-time and complexity of threat evaluation of radiation resource, an algorithm based on improved radar chart method (RCM) is proposed in this paper. In the algorithm proposed, coarse sorting is integrated with fine sorting to obtain a more accurate and reliable result of threat evaluation. Coarse sorting is applied to sequence all the radiation resource roughly according to radar operation mode, and reduce the task priority of low-threat radiation resource. Then, on the basis of improved RCM, fine sorting is applied to sequence the radiation resource with same radar operation mode. Finally, obtain the results of threat evaluation which combined coarse sorting with fine sorting. Simulation analysis shows the correctness and effectiveness of this algorithm. Comparing with classical method of threat evaluation of radiation resource based on RCM, the algorithm proposed in this paper is more visual in image and can work quickly with lower complexity.
Performance investigation of a volute porous tongue of a turbocharger turbine
Authors: Chachoua Abderrahmane , Kamal Hamidou Mohamed , Hamel Mohammed
Published: February 2020

The design for better performance of the spiral housing volute used commonly in radial and mixed inflow gas turbines is of prime importance as it affects the machine stage at both design and off design conditions. The tongue of the scroll divides the flow into two streams, and represents a severe source of disturbances, in terms of thermodynamic parameter uniformity, maximum kinetic energy, the right angle of attack to the rotor and minimum losses. Besides, the volute suffers an undesirable effect due to the recirculating mass flow rate in
near bottom vicinity of the tongue. The present project is an attempt to design a tongue fitted with cylindrical holes traversing normal to the stream wise direction, where on account of the large pressure difference between the top and the bottom sides of the tongue will force
the recirculating flow to go through the rotor inlet. This possibility with its limitations has not yet been explored. A numerical simulation is performed which might provide our suitable objectives. To achieve this goal the ANSYS code is used to build the geometry, generate the mesh, and to simulate the flow by solving numerically the averaged Navier Stokes equations. Apparently, the numerical results show evidence
of favorable impact in using porous tongue. The realization of a contact between the main and recirculation flow by drilled holes on the tongue surface leads to a flow field uniformity, a reduction in the magnitude of the loss coefficient, and a 20 % reduction in the recirculating mass flow rate.
Miradas nostálgicas en "Pozo de aire" de Guadalupe Gaona
Authors: Forné Anna
Published: February 2020

En Pozo de Aire la fotógrafa y poeta argentina Guadalupe Gaona traza desde el presente fragmentos de sus memorias de la infancia por medio de un ensamblaje de fotografías y breves poemas narrativos, antecedidos por un prólogo de carácter testimonial. Esta combinación de registros texto-visuales articulados por una voz poética omnipresente más esquiva, excede los horizontes de expectativa asociados a la configuración de las memorias de la segunda generación en Argentina porque se resiste a elaborar una historia prospectiva. En este artículo abordaré las especificidades estéticas de Pozo de aire enfocando en primer lugar en las relaciones entre sujeto y objeto a partir de la idea de una poesía camarógrafa y, en segundo lugar, propondré una lectura del texto a partir del concepto de nostalgia.

Published: February 2020

En este trabajo se presenta y se interpreta una recopilación de datos relacionados con la publicación y la difusión de la narrativa hispanoamericana actual en España entre 2009 y 2018. Con apoyo en la metodología de la lectura distante propuesta por Franco Moretti y en reflexiones teóricas sobre la relación entre crisis y literatura, se intenta indagar en la eventual consecuencia de la última crisis económica mundial en la reconfiguración del campo, en contraste con la situación durante la primera década del siglo XXI. Para ello, se han utilizado los listados de algunos de los premios más conspicuos; los dossiers y monográficos publicados en tres revistas especializadas (Ínsula, Cuadernos Hispanoamericanos y Quimera) y en los suplementos culturales de otros tres diarios (El Cultural, de El Mundo; Babelia, de El País, y ABC Cultural), numerosas declaraciones de agentes implicados en el campo hispanoamericano peninsular, así como el contenido de una decena de antologías publicadas en el periodo (no sólo en España) y de los catálogos de la editorial Literatura Random House, para aquilatar la deriva transatlántica del fenómeno.
AGROCHEMICAL PROPERTIES MONITORING OF THE VARIOUS LANDS WITHIN THE AGROLANDSCAPE
Authors: Ivanov D. A. , Karaseva O. V. , Rublyuk M. V.
Published: February 2020

The paper presents the results of a statistical analysis of data on long-term monitoring of the agrochemical properties of soils of various lands within the reclaimed agrolandscape. Research was conducted in 1997-2012. on the agroecological transect of the VNIIMZ polygon - a narrow field 1300 m long that intersects all the main landscape positions of the end moraine hill. During the monitoring, two rounds of agrochemical surveys of the transect territory were carried out: 1. In 1997, the initial state of the soils was investigated; 2. In 2012, the state of the soils of the output field and crop rotation array. Agrochemical parameters of soils (various types of acidity, content of plant nutrients and humus) were determined at the sampling points regularly located along the transect. The research results were statistically processed based on the STATGRAPHICS plus package. It was revealed that during the research, the same type of evolution of the agrochemical parameters of soils of different lands occurred - acidification of soils, loss of the basic elements of plant nutrition during the accumulation of humus are observed everywhere. By 2012, the spatial variability of most agrochemical parameters of soils of different lands mainly began to depend on the granulometric composition of soils. A significant difference was found in the mechanism of soil loss of potassium and phosphorus - potassium migration mainly depends on the intensity of eluvial processes in the agrolandscape, and phosphorus moves laterally along the plow sole. Based on the results obtained, it is possible to develop a system of adaptive land allocation in an agrolandscape, which allows controlling degradation processes in soils.

In nature, the freesia genus is distributed throughout the continent of South Africa. Most species selected at the end of the 19th century played an important role in the origin of cultivated varieties and hybrids. The paper presents the history of the development of the freesia culture in the world market of cut flower products, the selection research history in world practice and in the conditions of humid subtropics of Russia in the Sochi at the Russian Research Institute of Floriculture and Subtropical Crops. Promising direction of selection research on the promising new cultivars breeding characterized by high decorative qualities and resistance to local growing conditions are analyzed: obtaining triploid cultivars; breeding potted cultivars; intervarietal, interspecific, and heterogeneous crosses using ovule culture in vitro; researches using radiation mutagenesis and other means of a physical and chemical nature; receiving seed races. The issue of incompatibility of the original parental forms of one ploidy level remains open and requires a more detailed genetic analysis.
The genus Leptotoma Kiritch. et Samyl. (Ginkgoales): systematics and characteristics of the leaf epidermal structure
Authors: Nosova N. V.
Published: February 2020

Diagnostic features are systematized for the leaf epidermal structure of the Leptotoma Kiritch. et Samyl. The study of the new findings and the revision of the type material of L. kryshtofovichii Srebrod. et Samyl. from the Early Cretaceous of Eastern Transbaikalia reveal the occurrence of occasional stomata on the lateral epidermis as well as the presence of a central or proximal papilla on the subsidiary cells of the stomata, which allows to emend the specific diagnosis. The same sediments yield L. baikalica N. Nosova, sp. nov., that differs considerably from other Leptotoma species in its peculiar set of epidermal characters. For the first time, discrete resin ducts are found in the leaves of Leptotoma. The revision of type specimens of L. tenuis Samyl. and L. prynadae Travina from the Middle Jurassic of Kansk-Achinsk Coal Basin (Krasnoyarsk kray) suggests their affinity to Baiera. The re-investigation of the type material of L. borealis Travina and L. sibirica Kiritch. et Batjaeva from the Jurassic of Western Siberia indicates that these species should be merged, with L. sibirica kept as the priority name. For the first time for the Lower Cretaceous, findings of Leptotoma leaves are reported from the Maastrichtian of the Amur oblast (L. samylinae N. Nosova, sp. nov.).

Published: February 2020

Timelines are commonly represented on a horizontal line, which is not necessarily the most effective way to visualize temporal event sequences. However, few experiments have evaluated how timeline shape influences task performance. We present the design and results of a controlled experiment run on Amazon Mechanical Turk (n=192) in which we evaluate how timeline shape affects task completion time, correctness, and user preference. We tested 12 combinations of 4 shapes --- horizontal line, vertical line, circle, and spiral --- and 3 data types --- recurrent, non-recurrent, and mixed event sequences. We found good evidence that timeline shape meaningfully affects user task completion time but not correctness and that users have a strong shape preference. Building on our results, we present design guidelines for creating effective timeline visualizations based on user task and data types.

INPP1 is differentially expressed in platinum-resistant ovarian cancers.
Authors: Mamoor Shahan
Published: February 2020

Ovarian cancer is the most common reason for a gynecological cancer death in the developed world and fifth leading cause of cancer death in women in the United States (1, 2). Chemotherapy includes the use of platinum drugs (3) and resistance to platinum drugs is a serious problem for women diagnosed with ovarian cancer (4, 5, 6). We found, using two published datasets (7, 8) that INPP1 was one of the genes most differentially expressed when comparing the transcriptomes of platinum-resistant and platinum-sensitive tumors and cell lines but that the pattern of differential expression was opposite in cell lines versus that in primary tumors from patients. Manipulation of INPP1 expression should be assessed for its ability to reverse platinum resistance.
The reticular atomic filter in the vacuum. The adaptability of the electronic cloud of atoms with two applications: hydrogen and water.
Authors: D'Alonzo Giovanna
Published: February 2020

In the vacuum, some solids could be used as gas filters not only through the empty spaces of the crystal lattice but also through the electronic clouds of the atoms that make up the solid. With the use of particular equipment in the vacuum we could obtain a new energy, look for the energy sufficient for the adaptability of the electronic cloud and obtain a suitable temperature for the adaptability of the electronic cloud. In the case suppose that the electronic clouds of the atoms constituting the solid are valued by the ions, this energy is subtracted from ion ionization energy in the total energy of the molecules distribution and, through some mathematical passages, we deduce a temperature sufficient for the passageway of the electronic cloud suitable for some solids. An ion and/or an atom to be filtered should have a smaller diameter than the atomic radius of the atom that constitutes the filter, for the transition through the electronic clouds. The gases could cross the solid or in the empty spaces of the crystal lattice or in the electronic clouds of the atoms that make up the solid due to the difference between the force fields. Possible future applications could improve the quality of life, in particular it would be possible to reduce atmospheric pollution by producing molecular hydrogen which would become above all a solid ecological alternative for energy production and, therefore, a solid alternative to nuclear power.

Published: February 2020

We propose a new mathematical moment technique for the inverse problem of wave propagation in an inhomogenous (half-space) medium in the acoustical wave field Born approximation by using the analytical regulariazation scheme of the theory of quantum fields .
Risk Orientation Scale: A new clinically relevant measure of risk aversion
Authors: Brown Gary P.
Published: February 2020

Aversion to risk is a prominent factor in transdiagnostic theories of emotional problems, and it is included as an element in the research domain criteria. There is a plethora of risk scales across different domains, but most of these have notable shortcomings or are not suited for use in mental health research. The present study describes the development of the Risk Orientation Scale. Content was drawn from previous risk scales and separate classifications of risk. The factor structure of the ROS was derived in a clinically relevant sample and confirmed in two other independent non-clinical samples. The final 15-item ROS was found to have an adequate three-factor structure across clinical, general population and undergraduate student samples. Total and subscale scores covaried in the predicted direction with measures of risk taking behavior, underlying orientation towards reward and punishment, and clinical anxiety-relevant measures that have been theoretically linked to risk. The findings on the ROS thus support the idea that aversion to risk is a process that underlies anxiety disorders. The ROS can provide a brief and valid measure of this in both clinical and non-clinical populations. As it provides risk orientation towards specific domains, it can potentially aid in guiding clinicians in targeting important underlying mechanism in the treatment of anxiety disorders.
How Firm Are the Foundations of Mindset Theory? The Claims Appear Stronger Than the Evidence

Mindset refers to people’s beliefs about whether attributes are malleable (growth mindset) or unchangeable (fixedmindset). Proponents of mindset theory have made bold claims about mindset’s importance. For example, one’smindset is described as having profound effects on one’s motivation and achievements, creating different psychological worlds for people, and forming the core of people’s meaning systems. We examined the evidentiary strength of six key premises of mindset theory in 438 participants; we reasoned that strongly worded claims should be supported by equally strong evidence. However, no support was found for most premises. All associations (rs) were significantly weaker than .20. Other achievement-motivation constructs, such as self-efficacy and need for achievement, have been found to correlate much more strongly with presumed associates of mindset. The strongest association with mindset (r = –.12) was opposite from the predicted direction. The results suggest that the foundations of mind-set theory are not firm and that bold claims about mind-set appear to be overstated.
Some Researchers Wear Yellow Pants, but Even Fewer Participants Read Consent Forms: Exploring and Improving Consent Form Reading in Human Subjects Research

Though consent forms include important information, those experienced with behavioral research often observe that participants do not carefully read consent forms. Three studies examined participants’ reading of consent forms for in-person experiments. In each study, we inserted the phrase “some researchers wear yellow pants” into sections of the consent form and measured participants’ reading of the form by testing their recall of the color yellow. In Study 1, we found that the majority of participants did not read consent forms thoroughly. This suggests that overall, participants sign consent forms that they have not read, confirming what has been observed anecdotally and documented in other research domains. Study 2 examined which sections of consent forms participants read and found that participants were more likely to read the first two sections of a consent form (procedure and risks) than later sections (benefits and anonymity and confidentiality). Given that rates of recall of the target phrase were under 70% even when the sentence was inserted into earlier sections of the form, we explored ways to improve participant reading in Study 3. Theorizing that the presence of a researcher may influence participants’ retention of the form, we assigned participants to read the form with or without a researcher present. Results indicated that removing the researcher from the room while participants read the consent form decreased recall of the target phrase. Implications of these results and suggestions for future researchers are discussed.
Is Student Dropout at University a Multi-Staged Process? A Phase-Orientated View on Quitting Studies and Changing Majors

Student dropout can be conceptualized as a motivated decision-making process, consisting of different phases. Based on previous literature on student dropout, decision-making, and action-phases, we proposed that the process of developing dropout intentions includes the following phases: non-fit perception, thoughts of quitting, deliberation, information search, and a final decision. In the present study, we empirically investigated if the assumed phases can be distinguished from each other, if the phases follow the presumed order, and whether each phase is associated with certain characteristics. Furthermore, we considered a strict separation between quitting studies completely and changing a major. For this purpose, we analysed data of N = 1,005 students (average age of 23.0 years; 53% female; 47% male) from a German University. By using confirmatory factor analyses, we found the supposed factor structure for the different phases concerning both kinds of dropout, quitting studies and changing majors. In each process, latent mean scores followed the presumed order. The factor values correlated to a substantial amount with an assortment of variables associated with student dropout. On a theoretical level, the conception of different phases of student dropout helps to get a better understanding of regulatory processes in the context of student dropout.
Prawo właściwe dla skutków przelewu wierzytelności w stosunku do osób trzecich. Uwagi z perspektywy międzynarodowego prawa upadłościowego

The claims are rights in personam but the assignment of claims has a hybrid nature. Abolishing the “nomina ossibus inhaerent” rule has increased commercial significance of the assignment of claims. However, the contemporary legal situationleaves parties with great legal uncertainty, as to the question under which circumstances does the cross — borders assignment is valid. A recent judgment of the CJEU of 9 October 2019 (C — 548/18) in case BGL BNP Paribas SA v. TeamBank AG Nürnberg has augmented this uncertainty. The Luxemburg Court ruled that: “Article 14 of the Regulation (EC) No 593/2008 of the European Parliament and of the Council of 17 June 2008 (‘Rome I’) must be interpreted as not designating, directly or by analogy, the applicable law concerning the third-party effects of the assignment of a claim in the event of multiple assignments of the claim by the same creditor to successive assignees”. In this situation, one would highly welcome an attempt to establish a new set of conflict of laws rules relating to the law applicable to third — parties effects of the assignment of claims. This attempt has recently been made by the European Commission in its Report “on the question of the effectiveness of an assignment or subrogation of a claim against third parties and the priority of the assigned or subrogated claim over the right of another person”, dated 29 September 2016. In the present article, the author reviews the most important propositions formulated in the conflicts’ doctrine through the “lens” of the international insolvency law. Multiply provisions of the Regulation (EU) 2015/848 of 20 May 2015 on insolvency proceedings (recast) — despite many judgments of the CJEU in this area — also lack certainty. Insolvency is a foreseeable risk, but without clear rules concerning the third parties’ effects of the assignment of claims, it may become unenforceable for the creditors of the assignor.
Niejednoznaczne podstawy stosowania przepisów wymuszających swoje zastosowanie (przepisów koniecznego zastosowania)
Authors: Rodziewicz Piotr
Published: February 2020

The article raises issues concerning legal basis for the application of the overriding mandatory rules. In the Polish doctrine there are two opposing concepts in terms of explanation of the legal grounds for application of overriding mandatory rules. Both theories do not have a universal dimension, in the sense that they do not sufficiently explain the basis for the application of domestic as well as foreign overriding mandatory rules, being part of lex causae or coming from a third state. The article presents arguments for and against the possibility of deriving the legal grounds for application of the overriding mandatory rules, with reference to submissions made to that effect in literature. The author makes also an attempt to formulate a concept complementary to the concept of an integrated conflict-of-law rule with the substantive law rule, boiling down to the assumption that the basis for application of overriding mandatory rule is a second degree conflict of laws rule allowing to apply a first degree conflict of laws rule integrated with the substantive rule.
Glosa do wyroku Trybunału Sprawiedliwości Unii Europejskiej z dnia 12 lutego 2015 r. w sprawie Sähköalojen ammattiliitto ry c/a Elektrobudowa Spółka Akcyjna (C‑396/13)
Authors: Kurowski Witold

This paper aims to comment an important ruling concerning the Posted Workers Directive (Directive 96/71/EC). In the judgement C-396/13 (Sähköalojen ammattiliitto ry v. Elektrobudowa Spółka Akcyjna), the European Court of Justice providedits pro-worker’s interpretation of Art 3 of Directive 96/71/EC concerning the scope of the "minimum pay rate". The second issue raised by the European Court of Justice was the assignability of pay claims governed by Polish law based on Art 14 (2) of Rome I Regulation and prohibited under that law. In commented judgement, the Court admitted the assignment of claims arising from employment relationships in light of article 47 of the Charter of Fundamental Rights of the European Union and accepted the trade union’s right to represent the posted workers.
