Published: December 2019

Abstract
This study analyses the results of research on the improvement of grain quality using a filling core in a grain silo. The research is a part of the research project aimed at developing an innovative system for drying and storing maize grain that, among other benefits, reduces grain damage. Two series were carried out: a control series, in which a chute was applied as the main element, and an operation series, in which a cascade chute was used for testing. The analysis conducted on the simulated operating conditions showed a 4-5-fold reduction in the amount of grain damaged following the application of the filling core compared with the control series. It has also been shown that a 6-meter cascade chute considerably decreases the velocity of the falling grain when loading the silo.

Abstract
Laboratory specimen preparation methods can significantly influence the dynamic shear-induced volumetric response of sands. In this study, a medium dense to very dense Ottawa sand (relative density, DR = ∼60–95 %) was systematically tested using a multidirectional cyclic direct simple shear device to evaluate the influence of specimen preparation on drained cyclic volumetric strain. Both unidirectional and bidirectional cyclic loads were applied to specimens created using four preparation techniques: dry funnel deposition, dry soil raining, dry funnel deposition followed by table vibrations, and dry funnel deposition followed by cyclic shearing. The results indicate that as DR increases, the effect of specimen preparation on volumetric strain decreases. Specifically, the results illustrate that volumetric strain of medium dense sand (DR = 57–74 %) is affected by specimen preparation, which is consistent with the literature. In contrast, dense to very dense specimens (DR &gt; 80 %) exhibited comparable volumetric strain independent of the specimen preparation method. This observation is consistent for both unidirectional and bidirectional cyclic loading.

AbstractThe lipid kinase PI4KB, which generates phosphatidylinositol 4‐phosphate (PI4P), is a key enzyme in regulating membrane transport and is also hijacked by multiple picornaviruses to mediate viral replication. PI4KB can interact with multiple protein binding partners, which are differentially manipulated by picornaviruses to facilitate replication. The protein c10orf76 is a PI4KB‐associated protein that increases PI4P levels at the Golgi and is essential for the viral replication of specific enteroviruses. We used hydrogen–deuterium exchange mass spectrometry to characterize the c10orf76‐PI4KB complex and reveal that binding is mediated by the kinase linker of PI4KB, with formation of the heterodimeric complex modulated by PKA‐dependent phosphorylation. Complex‐disrupting mutations demonstrate that PI4KB is required for membrane recruitment of c10orf76 to the Golgi, and that an intact c10orf76‐PI4KB complex is required for the replication of c10orf76‐dependent enteroviruses. Intriguingly, c10orf76 also contributed to proper Arf1 activation at the Golgi, providing a putative mechanism for the c10orf76‐dependent increase in PI4P levels at the Golgi.
La atenuación mediante la partícula discursiva ¿eh? en el lenguaje adolescente de Madrid
Authors: Jørgensen Annette Myre 
Published: December 2019

The discourse particle eh has a high frequency in the Madrid teenage talk. The different functions this short particle displays in the interaction, as for instance: calling upon the hearer’s attention, demanding approval or asking for a repetition of what is said, or hedging is worth some attention. One of the many functions attributed to this particle is the hedging one, especially when there are utterances containing speech acts conveying orders, critics and recriminations, which could imply a face threat. This paper will therefore describe the hedging function of the final interrogative ¿eh? in the oral speech among Madrid teenagers. Hedging is a pragmatic strategy by which the speaker minimizes the effects of the utterance. It can have impact on different elements in the communicative process: the message, the speaker, the hearer and the relation between both. Although teenagers are not known for their tendency to soften the content and effect of their sayings, there are several utterances among the Madrid teenagers that present a certain hedging through the particle ¿eh? in a final position.
The examples used in this study are extracted from the Corpus Oral de Lenguaje Aolescente, COLA-corpus (http://www.colam.org/), which contains spontaneous, informal teenage (13 to 19 years) talk from Madrid. There are more than 5000 concordances with ¿eh? displaying a wide array of functions in different positions in the utterance. The cases that have ¿eh? in a final position and a hedging function have been selected for the analysis of this paper.

Published: December 2019

Set in Ontario, which is the most diverse province in Canada, this study (N = 76) examined Internationally Educated Teachers’ (IETs) and non-Internationally Educated Teachers’ (non-IETs) sense of self-efficacy for providing linguistically and culturally inclusive pedagogy in K-12 classrooms. Theories of self-efficacy and culturally responsive pedagogy frame this research. This study employed a quantitative 40-item survey to compare teachers’ self-efficacy perceptions of general pedagogy and culturally responsive pedagogy. Results show that while both groups were equally consistent in their self-efficacy perceptions for providing general pedagogy, IETs reported significantly higher self-efficacy for providing culturally responsive pedagogy.
Réalisée en Ontario, la province la plus diversifiée du Canada, auprès d’enseignantes et enseignants formés à l’étranger (IETs) et d’enseignantes et enseignants formés ailleurs qu’à l’étranger (non-IETs), cette étude rend compte de la mesure dans laquelle ces professeurs se sentent personnellement capables d’offrir efficacement une pédagogie linguistiquement et culturellement inclusive dans les salles de classe de la maternelle à la douzième année. Éclairée par des recherches dans les domaines de l’auto-efficacité et de la pédagogie adaptée aux réalités culturelles, cette enquête quantitative basée sur la réponse à 40 questions a permis de comparer les perceptions d’auto-efficacité des enseignantes et enseignants à l’égard de la pédagogie en général et de la pédagogie adaptée aux réalités culturelles. Les résultats de l’enquête indiquent que, alors que les sentiments d’auto-efficacité des membres des deux groupes étaient uniformes quant à la pédagogie en général, les enseignantes et enseignants formés à l’étranger se sentent considérablement plus à même d’offrir une pédagogie adaptée aux réalités culturelles.

The limitations of the rooms in the hospital may be reasonable, but it will be a problem if this happens at certain times when there is an over the quota of patients such as during an outbreak of Dengue Fever or in the event of a natural disaster. Generally, patients must be willing to sleep on the floor just because of the limitations of the inpatient room and also the bed.
To help overcome this problem, especially to help paramedic needs, a multipurpose wheelchair is designed so that in addition to being able to be used as patient transportation, it can also be used as an examination table. The method used to develop the wheelchair starts from an inventory of wheelchair needs, concept development, and selection. The reference used for concept development is a conventional wheelchair while the criteria set for the variety of concepts are the function, operational ease and convenience (wheelchair wear ergonomics).
As the central part of the wheelchair, the frame is made of stainless steel pipes. To keep the seating position stable, the swing arm is used as a place to hang the seat on the mainframe. The cross position in the middle of the frame functions to keep the wheelchair symmetrical and can be folded when not in use. Semicircular discs with seven keyholes, each of which is spaced 150, are used as a system for backrest mechanisms to allow them to lie down. The rack and pinion system is used as a mechanism for wheelchair lifting when it is functioned as an examination table. Ergonomics analysis with the help of Catia software using the RULA method, the grand score obtained is 3. So that the design of the wheelchair is quite safe

Confusão na evolução
Authors: Pioker-Hara Fabiana Curtopassi , Faht Elen Cristina 
Published: December 2019

O ensino de evolução encontra muitos desafios, dentre eles, a compreensão do tempo geológico pelos estudantes. Nesse sentido, filmes animados que tratam de seres que viveram em eras pretéritas podem servir de ponto de partida para discussões acerca do tema. Este trabalho, parte de uma pesquisa em andamento, traz a análise de duas animações infantis (Em Busca do Vale Encantado e A Era do Gelo 3) acerca da presença de anacronismos na construção das personagens. Pontuamos e discutimos também o contexto geológico e paleoclimático das histórias. Notamos que Em Busca do Vale Encantado tem um certo rigor científico na construção das personagens e da história, embora tenha dois personagens anacrônicos. Já A Era do Gelo 3, além de retratar como contemporâneos animais separados por milhões de anos, trata da última glaciação do Pleistoceno como o único evento de glaciação desde os dinossauros. Do ponto de vista didático, os dois longa-metragens têm potencial para compor a discussão sobre tempo geológico em sala de aula. Pretendemos futuramente criar uma ferramenta didática para auxiliar o professor de ciências na abordagem da macroevolução e do passado geológico e climático do planeta.
Approach to design of distributed multi-agent system for processing sound information of the environment
Authors: Vishniakou U. A. , Shaya B. H. 
Published: December 2019

The processes of measurement, recording and analysis of different sound levels are considered. The amplitude and effect of sound waves vary considerably in continuous space-time measurements. Modeling different types of sounds and their spatiotemporal effects becomes important for assessing the sound situation both in working spaces and in recreation areas. Developing a model that reflects the characteristics of sounds, their sources, and the rules that govern their distribution in different environments would help track sound variations and predict their future changes for spatiotemporal states. Similar works abroad are given, but they are of a private nature. There are many features that you can use to describe audio signals. We consider a wide range of objects to evaluate the effect of each object and select the appropriate set of objects to distinguish between classes. Two estimations of a sound situation are given: on the basis of short-term energy and average speed of change. Three different classification methods are investigated: KNearest neighbors, Gaussian mixture model and Support vector machine.Multi-agent system (M)AS characteristics are given, the classification, trends in the use of multi-agent intelligent technologies for information processing are presented. Authors propose the use of MAS for sound information (MASSI) monitoring. MFSSI structure includes many agents of sound transformation, analysis of information received from them and decision-making. MASSI can handle noise levels in the urban space and to help in the study of noise pollution in many areas.
Unlocking the Potential: Understanding the Psychological Factors That Influence Technology Adoption in the Upstream Oil and Gas Industry
Authors: Roberts Ruby , Flin Rhona 
Published: December 2019

Summary
To maximize the opportunities for the adoption of newly developed products, there is a need to better understand how psychological factors have an impact on the acceptance and deployment of innovative technology in industry. While there is extensive general literature on the psychological factors that influence consumer behavior and the use of new technologies, there seemed to be very limited understanding of this topic, specifically relating to the upstream energy sector. A literature review was conducted to (1) identify what, if any, research has been conducted in relation to the psychological factors influencing technology adoption and deployment in the oil and gas (O&G) industry and (2) identify what interventions have been developed to support technology adoption in O&G.
A literature search was undertaken, and given the limited research anticipated, minimum selection criteria were applied on the basis of Cochrane quality control (Higgins and Green 2011). In the 17 articles that met the search criteria, there was limited discussion of the psychological factors that have an impact on O&G technology adoption. The articles were subject to Braun and Clarke (2006) thematic analysis, producing a list of psychological factors that influence technology adoption in O&G.
Only five psychological factors were identified: personality (e.g., exploration traits and risk aversion), attitude (e.g., trust and not-invented-here syndrome), social (e.g., social norms), cognition (e.g., risk perception), and psychological factors at an organizational level (leadership and organizational culture). In addition, our review identified a small number of interventions that were developed and deployed to support technology adoption in O&G.
Given the early stages of this research area, combined with the relevance for technology innovation in upstream O&G, our review adds to the literature by identifying an initial framework of the key psychological factors. This essential set of factors can be used to direct future research, as well as to support effective interventions aimed at supporting the introduction of new technology.
Calculation of Perforated Vertical and Horizontal Well Productivity in Low-Permeability Reservoirs
Authors: Wu Minglu , Zhu Jiamin , Li Longlong , Li Pengguang 
Published: December 2019

Summary
This paper presents the productivity formulas of a perforated vertical well on the basis of the dual-radial-flow model and then presents the productivity formulas of horizontal wells on the basis of disturbing elliptical flow theory. The threshold pressure gradient (TPG) is used to characterize the seepage characteristics of low-permeability reservoirs. By combing the above formulas, the authors proposed the productivity formulas of perforated horizontal wells in a low-permeability reservoir on the basis of the triple-radial-flow model. The formulas are derived considering the cases of the damaged zone being penetrated and being partially penetrated. At the same time, the flow patterns of single-phase flow and oil/water two-phase flows are considered. Sensitivity analysis on the performance of the perforated well shows that the productivity increases with the increase of the length of the horizontal well, penetration depth, shot density, perforation diameter, and phasing, and it decreases with the increase of TPG, compaction thickness, and crush degree of the crushed zone; the influence of the length of the horizontal well, TPG, penetration depth, shot density, compaction degree, phasing, perforation diameter, and compaction thickness on the productivity is in descending order.
Patients’ experiences of discontentment one year after total knee arthroplasty- A qualitative study

Published: December 2019

AbstractBackground Total knee arthroplasty is a common procedure with generally good results. However, there are still patients who are discontented without known explanation. Contentment and discontentment have previously been captured by quantitative designs, but there is a lack of qualitative studies regarding these patients’ experiences. Qualitative knowledge might be useful in creating strategies to decrease the discontentment rate. Methods Of the 348 patients who responded to a letter asking if they were contented or discontented with their surgery, 61 (18%) reported discontentment. After excluding patients with documented complications and those who declined to participate, semi-structured interviews were conducted with 44 patients. The interviews were analyzed according to qualitative content analysis. The purpose was to describe patients’ experiences of discontentment one year after total knee arthroplasty. Results The patients experienced unfulfilled expectations and needs regarding unresolved and new problems, limited independence, and need for buttresses. They were bothered by pain and stiffness, and worried that changes were complications as a result of surgery. They described inability to perform daily activities and valued activities. They also felt a need for buttresses, and a lack of respect and continuity, support from health care, and information adapted to their needs. Conclusion Patient expectation seems to be the major contributing factor in patient discontentment after knee replacement surgery. This qualitative study sheds light on the meaning of unfulfilled expectations, in contrast to previous quantitative studies. The elements of unfulfilled expectations need to be dealt with both on the individual staff level and on the organizational level. For instance, increased continuity of healthcare staff and facilities may help to improve patient contentment after surgery.
Oxytocin Receptor Gene, Childhood Maltreatment and Borderline Personality Disorder among Male Inmates in China
Authors: Zhang Min , Liu Na , Chen Haocheng , Zhang Ning 
Published: December 2019

Abstract
Background: Borderline personality disorder (BPD) is caused by a variety of biological and environmental factors. Accumulating evidence suggests that childhood maltreatment is a risk environmental factor in the development of BPD, but research on the genetic pathology of BPD is still in its early stages, and very little is known about the oxytocin receptor (OXTR) gene. The purpose of this study is to further explore the interactive effects between OXTR gene polymorphisms and childhood maltreatment on BPD risk.
Methods: Among the 1804 male inmates, 765 inmates with high risk were included in this study. Childhood maltreatment, BPD, antisocial personality disorder (ASPD) and impulsivity were measured by self-reported questionnaires. Peripheral venous blood was collected for the genotype test.
Results: Analyses revealed that the BP group had higher rs53576 AA genotype frequency and rs237987 AA genotype frequency than the non-BP group. Total childhood maltreatment score, emotional abuse and neglect could positively predict BPD risk. Among the high-risk samples, rs53576 GG genotype carriers had higher BPD scores at higher levels of physical abuse and sexual abuse and had lower BPD scores at lower levels of physical abuse and sexual abuse.
Conclusions: The findings suggest that the interaction between OXTR gene variations and childhood maltreatment is an important mechanism for the development of BPD. The moderating role of the OXTR gene provides evidence for gene plasticity.

Abstract

Background: Renalase is a flavoprotein that plays a protective role in chronic kidney disease and cardiovascular diseases. The secretion and way of action of this protein are still discussed. The aim of our study was to estimate the balance between serum and urine renalase in healthy individuals and chronic kidney disease (CKD) patients, using two parameters: fractional excretion (FE) and serum-to-urine renalase ratio (StURR). Methods: Our study involved 28 healthy volunteers and 62 patients with CKD in stages I to IV. The concentration of renalase in serum and urine was measured using an enzyme-linked immunosorbent assay (ELISA) kit (EIAab, Wuhan, China). We analyzed associations between renalase levels in urine and serum, and other parameters: sex, age, GFR, presence of hypertension, diabetes, and proteinuria, and determined the serum-to-urine renalase ratio and fractional excretion of renalase. Results: Renalase and serum-to-urine ratio were significantly higher in CKD patients in comparison with the control group. Fractional excretion was lower in CKD patients but this difference did not reach the statistical significance (p=0.092). Multivariate analysis performed in the CKD group showed, that from mentioned parameters, serum renalase was the only significant independent factor strongly positively associated with urinary renalase concentration. Conclusions: The serum-to-urine ratio is significantly and about 6.5-fold higher in CKD patients, and the fractional excretion of renalase is 3-fold, but not significantly lower in CKD patients. Renalase levels in both serum and urine are not related to glomerular filtration rate and not associated with blood pressure.
