Effects of the perceptions of online quizzes and electronic devices on student performance
Authors: Di Meo Fabrizio , Martí-Ballester Carmen-Pilar
Published: June 2019

This study assessed how students’ perceptions of online quizzes and the use of three electronic devices to solve them affected their performance. A sample of 208 students enrolled in an introductory accounting course at the Universitat Autònoma de Barcelona completed online quizzes as part of their evaluation and filled in a questionnaire on their perceptions of such quizzes and the electronic devices they used to do them on. Their scores were collected both for the online quizzes and their examinations, and the data were then analysed using a partial least square structural equation model. Findings suggest that a positive perception of online quizzes positively affected students’ examination scores, but not their scores for the online quizzes. The findings also indicate that, while positive perceptions of computers and tablet PCs for doing online quizzes did not affect students’ examination scores, those who reported positive perceptions of the use of mobile phones for online quizzes obtained significantly lower examination scores than their peers. Finally, perception of the use of any electronic device did not affect students’ scores for online quizzes. Implications for instructors, faculty administrators, and students are provided based on the results.
User guidance for efficient fact checking

Published: June 2019

The Web constitutes a valuable source of information. In recent years, it fostered the construction of large-scale knowledge bases, such as Freebase, YAGO, and DBpedia. The open nature of the Web, with content potentially being generated by everyone, however, leads to inaccuracies and misinformation. Construction and maintenance of a knowledge base thus has to rely on fact checking, an assessment of the credibility of facts. Due to an inherent lack of ground truth information, such fact checking cannot be done in a purely automated manner, but requires human involvement.

In this paper, we propose a comprehensive framework to guide users in the validation of facts, striving for a minimisation of the invested effort. Our framework is grounded in a novel probabilistic model that combines user input with automated credibility inference. Based thereon, we show how to guide users in fact checking by identifying the facts for which validation is most beneficial. Moreover, our framework includes techniques to reduce the manual effort invested in fact checking by determining when to stop the validation and by supporting efficient batching strategies. We further show how to handle fact checking in a streaming setting. Our experiments with three real-world datasets demonstrate the efficiency and effectiveness of our framework: A knowledge base of high quality, with a precision of above 90%, is constructed with only a half of the validation effort required by baseline techniques.
Multi-dimensional balanced graph partitioning via projected gradient descent

Published: June 2019

Motivated by performance optimization of large-scale graph processing systems that distribute the graph across multiple machines, we consider the balanced graph partitioning problem. Compared to most of the previous work, we study the
multi-dimensional
variant in which balance according to multiple weight functions is required. As we demonstrate by experimental evaluation, such multi-dimensional balance is essential for achieving performance improvements for typical distributed graph processing workloads.

We propose a new scalable technique for the multidimensional balanced graph partitioning problem. It is based on applying randomized projected gradient descent to a non-convex continuous relaxation of the objective. We show how to implement the new algorithm efficiently in both theory and practice utilizing various approaches for the projection step. Experiments with large-scale graphs containing up to hundreds of billions of edges indicate that our algorithm has superior performance compared to the state of the art.
Efficient discovery of sequence outlier patterns
Authors: Cao Lei , Yan Yizhou , Madden Samuel , Rundensteiner Elke A. , Gopalsamy Mathan
Published: June 2019

ModernInternet of Things(IoT) applications generate massive amounts of time-stamped data, much of it in the form of discrete, symbolic sequences. In this work, we present a new system called TOP that deTects Outlier Patterns from these sequences. To solve the fundamental limitation of existing pattern mining semantics that miss outlier patterns hidden inside of larger frequent patterns, TOP offers new pattern semantics based oncontextual patternsthat distinguish theindependent occurrenceof a pattern from its occurrence as part of its super-pattern. We present efficient algorithms for the mining of this new class of contextual patterns. In particular, in contrast to the bottom-up strategy for state-of-the-art pattern mining techniques, our top-downReducestrategy piggy backs pattern detection with the detection of the context in which a pattern occurs. Our approach achieves linear time complexity in the length of the input sequence. Effective optimization techniques such as context-driven search space pruning and inverted index-based outlier pattern detection are also proposed to further speed up contextual pattern mining. Our experimental evaluation demonstrates the effectiveness of TOP at capturing meaningful outlier patterns in several real-world IoT use cases. We also demonstrate the efficiency of TOP, showing it to be up to 2 orders of magnitude faster than adapting state-of-the-art mining to produce this new class of contextual outlier patterns, allowing us to scale outlier pattern mining to large sequence datasets.

Published: June 2019

Despite extensive research on cryptography, secure and efficient query processing over outsourced data remains an open challenge. We develop communication-efficient and information-theoretically secure algorithms for privacy-preserving aggregation queries using multi-party computation (MPC). Specifically, query processing techniques over secret-shared data outsourced by single or multiple database owners are developed. These algorithms allow a user to execute queries on the secret-shared database and also prevent the network and the (adversarial) clouds to learn the user's queries, results, or the database. We further develop (non-mandatory) privacy-preserving result verification algorithms that detect malicious behaviors, and experimentally validate the efficiency of our approach over large datasets, the size of which prior approaches to secret-sharing or MPC systems have not scaled to.
A Gyermeki Viselkedés Kérdőív legrövidebb változatának (CBQ VS) magyar adaptációja
Authors: D. Molnár Éva , Kovács Dénes
Published: June 2019

Elméleti háttér: A kisgyermekek körében végzett temperamentumkutatások egyik legismertebb és leggyakrabban használt mérőeszköze a 3–8 éveseknek szánt Gyermeki Viselkedés Kérdőív (Children's Behavior Questionnaire; CBQ), amely különböző változatokban is létezik, és amelynek magyar nyelvű változata ezidáig nem állt rendelkezésünkre. Cél: Tanulmányunk célja a CBQ legrövidebb változatának (CBQ VS) magyar adaptációja és a mérőeszköz pszichometriai mutatóinak ismertetése a hazai kutatók számára. Módszerek: Vizsgálatunkban 5–7 éves gyermekek (n = 201) és szüleik (n = 201) vettek részt három magyarországi településről. A kérdőívet a gyermekek szülei (176 anya és 25 apa) töltötték ki. A CBQ VS-H mellett vizsgáltuk a gyermekek végrehajtó funkcióit is a HTKS és Day-Night tesztekkel. Eredmények: Az exploratív faktoranalízis eredményeként a magyar verzióban, hasonlóan az eredeti változathoz, három faktor különült el, amelyek jó belső megbízhatósági mutatókkal rendelkeztek: Erőfeszítés alapú kontroll (Cronbach-α: 0,76), Extraverzió (Cronbach-α: 0,78), Negatív érzelmi viszonyulás (Cronbach-α: 0,74). A temperamentum vizsgált dimenziói függetlennek bizonyultak a kitöltő személyétől (anya vagy apa), életkorától, családi állapotától és iskolai végzettségétől. Következtetések: Eredményeink alapján a Gyermeki Viselkedés Kérdőív legrövidebb változatának magyar verziója (CBQ VS-H) megbízhatóan működik, és alkalmasnak tekinthető a kisgyermekek temperamentumának és annak három dimenziójának vizsgálatára.
Casamento fatal entre religião e política: fonte de armadilhas para a igualdade de gênero (Introdução)
Authors: Razavi Shahra , Jenichen Anne , Heinen Jacqueline
Published: June 2019

O lugar ocupado pela religião no campo da política continua a afirmar-se há várias décadas. Enquanto as práticas religiosas retrocederam em alguns contextos (especialmente na Europa ocidental), elas tendem a crescer em escala mundial (Norris e Inglehart 2004). Além disso, o uso de argumentos religiosos na política continua sendo uma prática comum em toda uma série de países, desenvolvidos ou em desenvolvimento.
Política sexual nos Estados Unidos: o peso das comunidades religiosas
Authors: Bernstein Elizabeth , Jakobsen Janet R.
Published: June 2019

Esse artigo versa sobre a análise das alianças entre atores laicos e religiosos nos Estados Unido, a partir de um estudo do caso sobre a luta contra o tráfico. Ele mostra que o imbricamento entre religião e política tem, nesse caso, duas fontes: o peso das normas e valores veiculados pelas instituições laicas derivadas do protestantismo e a influência das organizações religiosas sobre a política americana – sobretudo a dos evangélicos conservadores, já há mais de quinze anos. A origem das medidas que favorecem as desigualdades de gênero ou de ordem sexual nos Estados Unidos é, portanto, ao mesmo tempo, laica e religiosa. Seria errôneo, todavia, pensar que a religião pende necessariamente para um sentido conservador e a laicidade para um sentido progressista.
Estimates for the elastic moduli of 2D aggregate of hexagonal-shape orthorhombic crystals with in-plane random crystalline orientations

Numerical finite element simulations on the homogenization problem for large samples of particular 2D hexagonal-shape-geometry random orientation aggregates from the base crystals of orthorhombic symmetry have been performed. At sufficiently large random-aggregate samples, the scatter intervals of the macroscopic 2D bulk and shear elastic moduli converge toward the Voigt-Reuss-Hill bounds, and then our recently constructed theoretical estimates, which have been specified for the aggregates.
Color and Categorical Claims
Authors: Holcombe Alex O
Published: June 2019

The effect of color on psychological functioning is the topic of a large literature. Published claims include that viewing blue causes calmness and that viewing red decreases test achievement. However, almost all these claims are made on the basis of testing just a single, or sometimes a few, hues. But colors like red are categories that comprise many perceptually distinct hues. Making a general claim about red on the basis of testing just one or two red hues may be akin to testing the reliability of one Toyota car and one Tesla car, finding that the Toyota is more reliable, and concluding that Toyotas are more reliable. This methodological issue was omitted from a recent literature review that was otherwise rather comprehensive. This article provides arguments for why this is a major issue and suggests ways to address it.
Cztery świadectwa święceń duchownych z diecezji krakowskiej z XV i XVI wieku
Authors: Kaczmarek Krzysztof
Published: June 2019

Z terenu średniowiecznej diecezji krakowskiej posiadamy niewiele materiałów pokazujących praktykę święceń tamtejszego duchowieństwa. Z wyjatkiem dwóch krótkich wykazów akolitów ordynowanych przez bp. Jana Rzeszowskiego nie znamy też żadnych imiennych wykazów duchownych wyświęconych przez tamtejszych ordynariuszy i sufraganów. Z tego względu w badaniach nad święceniami kleru w tej diecezji warto sięgać do zapoznanych w dotychczasowych badaniach świadectw święceń poszczególnych duchownych. Kwerenda przeprowadzona w aktach biskupich i księgach konsystorskich kilku diecezji należących do polskiej organizacji kościelnej późnego średniowiecza pozwoliła na odnalezienie świadectw trzech duchownych z diecezji krakowskiej z lat 1460–1531: Andrzeja (prawdopodobnie z Męciny Małej), Grzegorza z Olkusza oraz Jana z Jakimowic. Zawartość tych materiałów ma znaczenie dla studiów nad prozopografią krakowskiego kleru w XV i pierwszej połowie XVI wieku.
Kazanie Skargi Jana Matejki w kontekście ówczesnej wiedzy o epoce i poglądów na dzieje Polski
Authors: Słoczyński Henryk M.
Published: June 2019

Autorzy zajmujący się twórczością największego malarza dziejów Polski, Jana Matejki, długo nie prowadzili systematycznych badań licznych odniesień do konkretnej materii historycznej w jego dziełach, ignorując ten ich aspekt, któremu artysta przypisywał szczególną wagę. W przypadku Kazania Skargi, jednego z najwybitniejszych jego dzieł, zmianę w tym zakresie przyniosła książka Jarosława Krawczyka Matejko i historia, ale autor skupił się tylko na jednym motywie: walce szlachty z tronem Zygmunta III. Publikowana tu rozprawa pokazuje, że niemniej ważne w treści obrazu są problemy unii religijnej oraz podporządkowania Polsce Rosji na początku XVI wieku. To poszerzenie interpretacji opiera się na próbie sprecyzowania, jaka wiedza o tych sprawach była dostępna artyście. Niewątpliwie szczególne znaczenie miała dlań inspiracja przyjaciela, Józefa Szujskiego, który wtedy opublikował traktujący o tej epoce tom Dziejów Polski. Ujęcie problemów tego okresu w tej książce oraz w obrazie wykazuje daleko idącą zbieżność, zaś istotą przesłania Kazania Skargi jest (znany także z innych dzieł Matejki) motyw utraconej przez Polaków wielkiej szansy dziejowej. Chodziło o szansę opanowania i ucywilizowania Moskwy, a konsekwencją jej utraty było powstanie ­imperium – przyszłego zaborcy Polski.
Infanticide and the Conflicts in Early Modern South Bohemia (1690–1710). Five Women from Jindřichův Hradec
Authors: Stůj Pavel
Published: June 2019

Early Modern Child-Murder Investigations Were Characterized by Many Conflicts and Struggles on Different Levels of the Social Organization. Sources like broadside ballads or pamphlets highlighted the infanticide as a matter of considerable public concern. There the conflict between idea of early modern motherhood and family life and the everyday life of single-mothers dealing with unwanted children was apparent. These moralizing pamphlets were describing virtues of motherhood like self-sacrifice, solicitude, economic and social responsibility and on the other hand authors criticized murdering mothers. Finally, conflicts, antipathy and personal confrontations between members of the family and sexual partners can be traced in these sources. Events prior the crime can be characterized by disagreements between sexual partners, violence and verbal abuse. This contextual analysis of conflicts in five infanticide proceedings from south Bohemia (1690–1710) is the centre of the paper.
Zachowane baldachimy procesyjne na terenie Małopolski z wieku XVII i XVIII
Authors: Tracz Szymon
Published: June 2019

Baldachimy procesyjne na terenie Małopolski w wieku XVII i XVIII przyjmowały formę dekoracyjnego daszku wykonanego zazwyczaj z tkaniny rozpiętej na stelażu, przymocowanego do ozdobnych drążków, co umożliwiało ich przenoszenie. Przede wszystkim baldachimów używano podczas procesji teoforycznych. Wykonywano je z zasady z nietrwałych materiałów, stąd też zachowało się ich tylko kilka. Na podstawie źródeł archiwalnych oraz zachowanych przykładów baldachimy procesyjne można podzielić ze względu na kształt na dwa rodzaje.Pierwszy, najliczniejszy, stanowią baldachimy o drewnianym lub metalowym stelażu na rzucie prostokąta zbliżonego do kwadratu, zaopatrzone w dwa lub cztery drążki. Drugi to baldachimy owalne na jednym drążku w kształcie parasola. W obu grupach najistotniejszym elementem dekoracyjnym była tkanina rozpięta na stelażu tworząca podniebie oraz dach baldachimu, kształtująca także jego boki za pomocą falbany lub lambrekinu. Podniebie i dach baldachimu wykonywane były zasadniczo z dwóch różnych tkanin. Dach baldachimu najczęściej był płaski, ale występowały także przykłady o dynamicznych formach, czego przykład stanowi baldachim w Kacwinie z drugiej połowy XVIII wieku. Dodatkowo stosowano dekoracyjne uzupełnienia w postaci obszycia galonem, koronką, frędzlą, taśmami i haftem, a także chwostami. Najczęściej drzewce baldachimów były rzeźbione i malowane. Najlepszym przykładem klasycznego baldachimu barokowego stanowi najstarszy zachowany w Małopolsce baldachim z  roku ok. 1663 w Polance Wielkiej lub baldachim wykonany z XVII-wiecznej tkaniny w kolegiacie św. Anny w Krakowie. Zdarzało się, że dach baldachimu był obwiedziony ażurowym, bogato rzeźbionym i złoconym obramieniem, jak np. baldachim z trzeciej ćwierci XVIII wieku w Krzywaczce lub w kościele św. Anny w Nowym Targu (2. poł. XVIII w.). Ciekawą grupę tworzyły baldachimy w całości drewniane dekorowane malowaną i złoconą snycerką, które zachowały się na Spiszu, w kościele we Frydmanie (2. poł. XVIII w.), Krempachach (2. poł. XVIII w.) i Trybszu oraz znany ze zdjęć archiwalnych niezachowany baldachim z końca XVIII wieku w Łapszach Niżnych. Zasadniczym elementem dekoracyjnym wymienionych baldachimów jest bogato rzeźbiony i złocony drewniany stelaż, do którego przytwierdzany był dach wykonany z tkaniny bądź z deski.Drugi rodzaj baldachimów w formie rozkładanego i składanego parasola reprezentowała niezachowana obecnie XVIII-wieczna umbella w Bielanach k. Kęt.Powstające w następnych stuleciach baldachimy generalnie przyjęły formę opartą na prostym drewnianym stelażu z tekstylnym dachem i bokami prostymi lub w formie lambrekinu. Spotykane są także rozwiązania, w których do elementów tekstylnych dodawano akcenty snycerskie.
Finite-element modelling of concrete-filled steel tube columns wrapped with CFRP
Authors: Abdalla Khairedin M. , Al-Rousan Rajai , Alhassan Mohammad A. , Lagaros Nikos D.
Published: June 2019

Experimental evaluation of the structural behaviour of concrete-filled tubular (CFT) circular steel columns under the combined effects of axial and cyclic lateral loads is costly and challenging. This study provides a non-linear finite-element analysis (FEA) of 21 models of CFT circular steel columns wrapped with several carbon-fibre-reinforced polymer (CFRP) composite layers at the end region, which represents the critical location in terms of lateral load capacity. The intent is to confine the column end to avoid outward local buckling of the column and thus develop high strength, larger net drift and more energy dissipation. The non-linear FEA models were properly calibrated and validated with reputable experimental results; a parametric study was then conducted to assess the influence of the number of CFRP layers and axial load level on CFT circular steel column performance. Also, it was found that the column axial load level significantly affects the CFT circular steel column behaviour under lateral loading, behaviour improved as the axial load level increased. It takes a parametric investigation, in terms of strengthening system, and the findings of this study provide a useful guideline and methodology for similar strengthening of CFT steel columns.

Objective. To evaluate possibilities and advantages of SpyGlass DS system (Boston Scientific) in the diagnosis and treatment of pancreato-biliary diseases. Material and methods. SpyGlass DS has been applied in 24 interventions in 22 patients for the period from December 6, 2017 to July 6, 2018. There were 21 cholangioscopies, 2 pancreaticoscopies and one cholangiopancreaticoscopy. The indications for cholangioscopy were undifferentiated strictures (n = 14), suspected Mirizzi syndrome (n = 2), large choledocholithiasis and need for laser lithotripsy (n = 1). There was a need to pass a guidewire under visual control (n = 2) and to control bile duct stones extraction (n = 1). Scheduled removal of ligature after laparoscopic cholecystectomy was in 1 case. Indication for pancreaticoscopy was suspected malignancy within the strictures associated with chronic pancreatitis, for cholangiopancreaticoscopy – assessment of spread of major duodenal papilla tumor into common bile and pancreatic ducts. Results. Overall technical success rate was 95.8% (23/24). Intraductal biopsy was successfully performed in 13 out of 14 (92.9%) cases. Cholangiocarcinoma was histologically confirmed in 6 cases. Curative interventions were performed in all 4 cases. There were no complications and mortality. Conclusion. The main indications for endoscopic peroral intraductal interventions are various types of undifferentiated and complicated biliary and pancreatic strictures, as well as “difficult” bile and pancreatic duct stones. The technology of diagnostic and curative endoscopic interventions using the SpyGlass DS system is relatively simple while morbidity and mortality rates are similar to those after conventional transpapillary interventions.

Objective. To analyze safety and efficacy of X-ray surgical treatment of choledocholithiasis in case of failed endoscopic procedures. Material and methods. A retrospective analysis included 195 patients with choledocholithiasis who underwent X-ray surgical treatment. Primary X-ray surgical intervention was antegrade cholangiostomy. Data of antegrade cholangiography were used to determine type of endobiliary intervention. Antegrade mechanical and pneumatic choledocholithotripsy and lithoextraction, balloon dislocation of stones of the common bile duct into duodenum or jejunum, lithoextraction using rendezvous technique after endoscopic papillotomy through transpapillary drainage tube or a wire were applied. Results. Puncture and drainage of non-dilated bile ducts were successfully performed in 30 (15.4%) patients. There were 212 procedires of cholangiostomy in 195 patients including redo interventions. Complications after cholangiostomy were absent in 92.9% of cases. Minor complications occurred in 7.1% of cases. Antegrade mechanical and pneumatic choledocholithotripsy and lithoextraction was performed in 118 (98.3%) patients. Balloon dislocation of stones of the common bile duct into duodenum was applied in 52 (81.3%) patients. Lithoextraction using rendezvous technique after previous endoscopic papillosphincterotomy was performed in 12 (60%) patients. Six patients underwent transpapillary external-internal drainage of common bile duct. Five patients had stricture of biliodigestive anastomosis complicated by cholelithiasis. Lithotripsy and lithoextraction through antegrade approach or dislocation of stones into jejunum after previous balloon dilatation were performed in these patients. Postoperative mortality was 1.5%. Minimally invasive techniques were absolutely effective for choledocholithiasis in 187 (98.9%) patients. Conclusion. Antegrade X-ray surgical management is effective and safe in patients with choledocholithiasis and unsuccessful previous endoscopic procedures. Integral efficiency of antegrade management of cholelithiasis was 88.8%.

Published: June 2019

Approaches and results of endoscopic transpapillary procedures in the treatment of patients with obstructive jaundice of various origins are analyzed. Modern trends in the development of endobiliary surgery and recommendations devoted to various endoscopic techniques and methods of biliary decompression depending on etiology and severity of obstructive jaundice, management of patients and dates of interventions are described. Leading specialized centers are characterized by quite high effectiveness of endoscopic transpapillary interventions in patients with cholelithiasis complicated by obstructive jaundice (95.2–97.5%), benign biliary strictures (63.7–92.8%) and biliopancreatoduodenal malignancies (70–96.8%). Analysis of modern tactical and technical approaches and international guidelines for transpapillary interventions allowed us to determine the current capabilities of retrograde minimally invasive curative technologies, systematize and optimize the basic algorithms for endoscopic care in patients with obstructive jaundice, and outline the prospects for the introduction and improvement of the effectiveness of new techniques.
Modeling the mass transfer processes in the growth of KDP crystals from solution
Authors: Verezub N. A. , Manomenova V. L. , Prostomolotov A. I.
Published: June 2019

Finding the conditions of high-speed single crystal growth with an appropriate quality is a priority for the industrial production of crystalline materials. Crystals of potassium dihydrogen phosphate (KDP) are important optical materials, they are grown from an aqueous solution and an increase in the rate of growth and quality of a single crystal is of great practical importance.

In this paper, mathematical simulation of hydrodynamic and mass transfer processes in growing KDP crystals is performed. The flow and mass transfer are modeled within the framework of continuous medium, which is considered as an aqueous solution of a special salt — potassium dihydrogen phosphate. This salt dissolves in water to a saturation level at a high temperature. Then, such supersaturated solution is used to grow crystals at lower temperatures in non-flowing and flowing crystallizers. The mathematical model is considered in a conjugate formulation with allowance for mass transfer in the

«solution—crystal» system. Local features of hydrodynamics and mass transfer in a solution near the surface of a growing crystal are determined, which can affect on the local (for a particular place and direction) crystal growth rate and the formation of defects. The requirements to the crystallizers that provide the «necessary» hydrodynamics in the solution are discussed. Its validation is shown for the flow around a long horizontal plate simulating the growing facet of the crystal. The rate of precipitation of salt was evaluated by the proposed mathematical model, which matches the calculation of solution flow according to the Navier-Stokes equations for an incompressible fluid with a thermodynamic condition for the normal growth of a face under conditions of two-dimensional nucleation. The action of the flowing crystallizers was analyzed for various solution inflows (axial and ring) and its outflow through the axial bottom hole.

Published: June 2019

In the heat «cooling» investigated the temperature dependence of the specific heat capacity and thermodynamic functions doped strontium alloy AK1М2 in the range 298,15—900 K. Mathematical models are obtained that describe the change in these properties of alloys in the temperature range 298.15—900 K, as well as on the concentration of the doping component. It was found that with increasing temperature, specific heat capacity, enthalpy and entropy alloys increase, and the concentration up to 0.5 wt.% of the alloying element decreases. Gibbs energy values have an inverse relationship, i.e., temperature — decreases the content of alloying component — is up to 0.5 wt.% growing.
The getters in silicon
Authors: Kharchenko V. A.
Published: June 2019

The processes of gettering of fast-diffusing metal impurities and structure defects in silicon, mainly used in the production of integrated circuits, power high-voltage devices, nuclear-doped silicon, are considered. The getters based on structural defects and gas-phase getters based on chlorine-containing compounds are analyzed. It is noted that for the formation of getters on the basis of structural defects, it is necessary to create internal sources for generation of dislocations and formation of precipitate — dislocation clusters. It is shown that dislocations are generated in the mouths of microfractures, which then form a sedentary dislocation grid on the non-working side of the plates. In the second case, defects are created in the area of the plate adjacent to the active layer of the electronic component. The process of creating an internal getter is based on the decomposition of a supersaturated solid oxygen solution in silicon, due to which a complex defect medium consisting of various precipitate-dislocation clusters is formed in the crystal. The packing defect as oxide precipitate with a cloud of Frank’s loops is formed. Two variants of creating an internal getter are considered — first is associated with the distillation of an oxygen impurity from the near-surface region of the plate, the second is associated with a fine adjustment of the distribution of vacancies along the plate thickness. The analysis of the influence of the getter as the defect structure reducing the magnitude of mechanical stress of the beginning of the generation of dislocations, which ultimately can determine the mechanical strength of the silicon wafer.

This paper also considers the mechanism of gas-phase medium impurities and defects gettering with the addition of chlorine-containing compounds. It is shown that at elevated temperatures, due to the interaction of silicon atoms with chlorine in the near-surface region of the plate, it is possible to create vacancies that penetrate the sample volume with some probability. As a result, the case DСv > 0, DCi £ 0 is realized, that leads to a change in the composition of microdefects and their density. The examples of practical application of heat treatment in chlorine-containing atmosphere silicon wafer during application of the oxide film, in the case of the target the need for dissolution of the microdefects and of the withdrawal of fast diffusing impurities from the crystal volume, and to prevent the formation of generation-recombination centers in the manufacturing process of devices and in a nuclear doping silicon.
RNA extractions from de-etiolated Arabidopsis seedlings using CTAB v1

Published: June 2019

A CTAB based method for extracting RNA, which is particularly useful for tough tissues. This has been adapted from a protocol that was originally used for pine tree tissue, which is difficult due to the high concentrations of polysaccharides, phenolics, and RNase (Chang, S., Puryear, J. & Cairney, J. Plant Mol Biol Rep (1993) 11: 113. https://doi.org/10.1007/BF02670468). The protocol described herein was an effective alternative to TRIzol based extractions for recovering RNA from juvenile de-etiolated tissues.
Standard method for microCT-based additive manufacturing quality control 5: witness specimen analysis v2
Authors: Du Plessis Anton
Published: June 2019

MicroCT is a well known technique and is often used for non-destructive analysis of parts produced by additive manufacturing. This is especially useful to inspect the parts for potential defects such as excessive porosity or layered defects due to imperfect powder levelling in individual layers. While various online monitoring methods are under development, there is currently not yet any accepted method to identify such defects during the building process. Post-production microCT of the entire part allows for the identification of such errors, but its limitation is the resolution which depends on part size. Hence a large part may have small but important porosities which may be missed by microCT. This can be overcome by using a witness specimen built in the same process, and analysing this smaller sample at a high resolution. The porosity information from the smaller part can be used to evaluate the acceptability of the entire build. The workflow presented here serves to standardize this process: with a simple process, a standard geometry witness specimen and hence standardized scan and analysis procedures. A layered stop-start flaw is shown in the witness specimen to demonstrate the ability to detect this type of flaw.

Published: June 2019

This protocol describes a robust and easy method for nuclei isolation for frozen tissues based on unpublished work by Drokhlyansky et al. This protocol is compatible with 10X droplet-based single-cell technology. This method is part of a toolbox for processing frozen tissue samples, including the TST (this protocol), CST and NST protocols (all available in protocols.io). We recommend users to test all three protocols on their tissue type of interest, and perform side-by-side comparison of the data generated. For the HTAPP project, this protocol was tested and validated for metastatic breast cancer, ovarian cancer, pediatric neuroblastoma and pediatric sarcoma frozen samples.

Penelitian ini bertujuan untuk mengetahui pengaruh integrasi kecakapan hidup (life skills) ke dalam program latihan renang. Sebanyak 60 perserta yang merupakan atlet renang dan non atlet terlibat dalam penelitian ini. Seluruh peserta tersebut kemudian dibagi menjadi tiga kelompok, yaitu (i) atlet renang yang memperoleh program renang yang terintegrasi dengan kecakapan hidup, (ii) atlet renang yang hanya diberikan program renang biasa tanpa muatan kecakapan hidup, dan (iii) non-atlet yang memperoleh program renang tanpa muatan kecakapan hidup. Metode yang digunakan dalam penelitian ini adalah the matching-only pretest-posttest control group design. Sebanyak delapan kecakapan hidup yang meliputi keterampilan kerja tim, menetapkan tujuan, keterampilan sosial, pemecahan masalah dan pengambilan keputusan, keterampilan emosi, komunikasi antar pribadi, kepemimpinan, dan manajemen waktu diintegrasikan ke dalam program latihan renang. Hasil penelitian menunjukkan bahwa terdapat perbedaan perkembangan kecakapan hidup antara kelompok atlet renang yang mendapatkan program renang terintegrasi kecakapan hidup dengan kelompok atlet renang tanpa program kecakapan hidup dan kelompok non atlet. Kelompok atlet renang yang memperoleh program renang dengan integrasi kecakapan hidup memiliki perkembangan kecakapan hidup yang lebih tinggi dibandingkan dengan dua kelompok lainnya. Hal ini menunjukan bahwa pemberian program kecakapan hidup secara disengaja terbukti mampu meningkatkan perkembangan kecakapan hidup atlet renang.

Published: June 2019

In modern conditions, the problems of economic security of socio-economic systems of various levels are in the focus of attention of Russian and foreign scientists. These problems are particularly acute for territories that have a pronounced source of raw materials and underdeveloped high-added value industries. Economic security of the city and the region cannot be ensured without due regard to the sectoral structure of the economy and the balance of budgets of all levels. An important indicator of the budget balance is the structure of the regional budget revenue, or, particularly, the structure of tax revenues to the budget, as well as the expenditure structure. The article discusses the distinctive formation features of revenue and expenditure parts of the regional and local budgets, analyses the most typical sources of revenue for different territories. The consolidated budget structure for the region and some municipalities based on the example of the Krasnoyarsk Territory (Krai) is analysed. The dynamics of revenues and expenditures is considered, the limitations stipulated by the regional law on intergovernmental relations are examined. As a result of the study, the authors arrived at the conclusions about the lack of balance between the analysed budgets, their inconsistency with the needs of the region, and, as a result, the existing threats to the economic security of the territory in question. The article contains recommendations on the development of economic activities in the Krasnoyarsk Territory that take into account the specifics of the studied region and that can improve the balance of local and regional budgets

Published: June 2019

Digitale Zwillinge für die Inbetriebnahme, Programmierung und Überwachung von Robotern finden im Maschinenbau immer breitere Anwendung. Bislang werden dafür kaum moderne Visualisierungstechnologien wie Augmented, Mixed oder Virtual Reality Methoden eingesetzt, obwohl damit neue Formen der Interaktion zwischen der Realität und dem Digitalen Zwilling möglich sind. Zurückzuführen ist dies unter anderem auf die plattform- und endgerätespezifische Entwicklung der Anwendungen sowie eine fehlende Vernetzung zwischen modernen Endgeräten, der Steuerungsebene und den Digitalen Zwillingen. Dieser Beitrag adressiert die beschriebenen Hemmnisse und schlägt als Lösung ein Konzept zur Modellierung, Ausführung und Bereitstellung von Digitalen Zwillingen in einer `Digital Twin as a Service´-Plattform vor. Die plattformunabhängige Interaktion zwischen Mensch und Simulationsmodell wird dabei durch eine Abstraktionsschicht sichergestellt. Das Konzept wird am Beispiel eines interaktiven, realdatengetriebenen Digitalen Zwillings eines kollaborativen Zweiarm-Roboters verifiziert.

Published: June 2019

El objetivo principal de este trabajo ha sido analizar las tasas recientes de progradación y retroceso del delta interior en la laguna de Los Micos, ubicada en el Caribe de Honduras, y determinar los factores antropogénicos y meteorológicos que han contribuido a la acelerada formación deltaica y los potenciales efectos sobre el sistema físico natural. Para ello, se han generado polígonos a partir de imágenes de satélite de la misión Landsat tomadas en los años: 1984, 1999, 2010 y 2014. Se han calculado las áreas de los polígonos y se ha analizado su evolución temporal. Se ha observado una tasa de progradación del delta de 38,45 m∙a-1, lo cual ha provocado una pérdida de superficie lagunar de   ̴ 6,77 ha∙a-1, como resultado del cambio de uso del suelo en la cuenca hidrográfica y los efectos de eventos meteorológicos severos como el Huracán Mitch.
Reconstrucción geomorfológica del último máximo glaciar en la cuenca del río San Juan, Argentina
Authors: Forte Ana Paula , Villarroel Cristian Daniel
Published: June 2019

Las glaciaciones cuaternarias han dejado registro en diversos espacios geográficos de la corteza terrestre. Esto no ha sido una excepción en los Andes Centrales de Argentina y Chile, donde enormes valles labrados por la erosión glacial y depósitos morrénicos evidencian el fenómeno. Sin embargo, aún no se ha logrado establecer a nivel regional el alcance geográfico de éstas glaciaciones, ni los volúmenes de agua que fueron descargados durante el retroceso de los glaciares. En éste trabajo se presenta un mapa geomorfológico de temática glacial de una región de los Andes Centrales y además se realiza por primera vez una reconstrucción geomorfológica de la zona en el momento del máximo avance glacial. Este trabajo ha sido realizado mediante el reconocimiento de las áreas ocupadas por valles en forma de U, valles asimétricos y depósitos morrénicos a partir de imágenes satelitales, fotografías aéreas y registro de geoformas en el campo. Los resultados obtenidos indican que en el área de estudio los glaciares pleistocenos llegaron a cubrir una superficie total de 582,3 km2, es decir, un 25,5% del total del área analizada (2.085 km2). Actualmente, en dicha zona los glaciares y heleros ocupan el 3,94 % de la superficie total.

Las Serres de Tramuntana y de Llevant, (Mallorca) tienen gran número de canchales de origen periglaciar, la mayoría de ellos activos. Debido a sus características geológicas y geomorfológicas, y a su singularidad se proponen 5 emplazamientos de canchal como Lugares de Interés Geológico (LIG). Esta propuesta se basa en su elevado interés científico y didáctico como ejemplos representativos de procesos sedimentológicos y geomorfológicos asociados al periglaciarismo insular manifestado en morfologías de canchales, y asociados un patrimonio etnológico correspondiente al comercio del hielo en Mallorca a través de las “cases de neu” que se sitúan en los ápices de dichas morfologías.

Published: June 2019

The authors determine the significance of the research of the value bases of the understanding of life activity by the representatives of the young generation for its productive inclusion in the system of social and industrial relations. The authors presented the results of the study of the axiological aspect of the idea of the success of university students belonging to the generation of centenials; The sample of the study was 591 students from three universities in Krasnoyarsk. The significance of success values was revealed by the method of S.A. Pakulina “The motivation for the success of university students.” The results of the study show that students’ perception of success contains a wide range of interrelated values. At the same time, the values of internalized (internally presented) success are of greater importance than the values of externalized (externally presented) success. The overall level of significance of the values of success is given by the cumulative effect of the values of the emotional state, personal success and the values of social significance. The authors describe the risks of such a structure of the axiological aspect of success for young people with a high focus on achievement.
