Authors: RADU CRINA , HERGHELEGIU EUGEN , SCHNAKOVSZKY CAROL , TAMPU CATALIN
Published: October 2018

Abrasive waterjet (AWJ) cutting technology is one of the most recent developed non-traditional processes used in industry for the processing of difficult-to-cut materials which usually lead to a pronounced wear of conventional tools and generation of damaged surfaces. The efficiency and the quality of AWJ depend on many parameters, some of them precisely controllable (e.g. water jet pressure, feed rate) while others uncontrollable (e.g. focusing tube size, waterjet orifice size). The aim of current study was to analyze the influence of feed rate at low working pressures on the quality of cuts, quantified by the parameters specified in the ISO/WD/TC44 N 1770 standard.

Published: October 2018

Stress assessment in the steel constructions is crucial for risk mitigation. NDT methods are widely used in such applications. However, many of these methods are hazardous, due to the radiation or chemicals used. The proposed magnetoelastic method is neutral to the natural environment. In this paper, development of such a method of stress assessment in constructional steel samples is presented. Measurements of the magnetic hysteresis loops of the sample members were performed under varying mechanical load on the specially designed steel truss test stand, which allowed to obtain magnetoelastic Bm(σ)Hm characteristics. The results confirm the feasibility of the new method of NDT stress assessment in the steel truss constructions.

Published: October 2018

The purpose of this paper is to review and present a short synthesis of the scientific literature on Ecolabel and an analysis of the types of products and services in Romania that obtained this environmental label. European eco-label is the only environmental quality label (type I; ISO 14024), awarded at institutional level (EC) valid all around the Europe, and it represents a unique opportunity to satisfy consumer expectations. In this way is promotes the design, production and marketing of products with lower environmental impact during their entire life cycle compared to other products in the same category. The EU Ecolabel covers a wide range of product groups, from major areas of manufacturing to tourist accommodation services. Key experts, in consultation with main stakeholders, develop the criteria for each product group in order to decrease the main environmental impacts over the entire life cycle of the product. Because the life cycle of every product and service is different, the criteria are tailored to address the unique characteristics of each product type. The European Ecolabel was introduced in Romania in 2002.

Published: October 2018

This study is a review of knowledge and understanding of organic fiber membrane behavior in wastewater ultrafiltration processes. Current research is increasingly focusing on the use of state-of-the-art technologies for the elimination of pollutants in water and the use of membranes. This study focuses on testing hollow fiber organic membranes for the ultrafiltration process as a precursor to osmosis processes. The major advantages of ultrafiltration are the elimination of many small organic and inorganic compounds from the water, which cannot be eliminated in microfiltration processes, offering superior quality water. This review highlights the effectiveness of organic membranes from hollow fibers in relation to the dependence between filtering parameters and those related to the membrane type structure, respectively the membrane structure of the polyacrylonitrile. The results of the study on the testing of such membranes have shown that filtration efficiency increases inversely with the degree of fouling on the surface of the membrane; the permeate quality being superior in the early stages of the membrane lifecycle, decreasing with increasing use time. In other words, the aging of the membrane decreases the volume of the permeate and at the same time changes the dependence of the parameters: pressure, temperature, flow if it is desired to obtain the same amount of permeate. Finding the best solutions for streamlining the membrane structure and running under the best conditions will be presented in the current paper.

Published: October 2018

Al-Qur’an adalah Kalamullah, sebagai mu’jizat, yang telah diturunkan kepada penutup para Nabi dan Rasul, Muhammad dengan perantara Jibril yang termaktub dalam mushaf-mushaf yang dinukil sampai kepada kita secara mutawatir, membacanya sebagai ibadah, yang dimulai dengan surah Al-Fatihah yang ditutup dengan surah An-Nas. Untuk membaca Al-Qur’an diperlukan pengetahuan tentang pedoman ilmu Tajwid. Dalam penelitian ini, metode Euclid Distance dan Bray Curtis Distance digunakan untuk menghitung jarak keakurtan pola Tajwid pada citra Al-Qur’an. Hasil pengujian menunjukan bahwa keakuratan sistem ini sebesar 70% hingga 90%. Persentase detection rate tersebut menunjukkan bahwa metode Euclid Distance dan Bray Curtis Distance dapat digunakan sebagai salah satu pendekatan untuk pendeteksian pola Tajwid pada citra Al-Qur’an, akan tetapi dari segi hasil Big Theta menyatakan bahwa algoritma Euclid Distance lebih efisien karena memiliki jumlah Big Theta yang lebih kecil dari Bray Curtis Distance. Sistem ini memiliki beberapa kelemahan yaitu memiliki false positive rate yang tinggi, dapat dilihat pada unjuk kerja dari sistem pendeteksi Tajwid ini, proses keakurasiannya dapat dilakukan dengan memberikan pelatihan lebih lanjut dengan tambahan data training yang lebih banyak dan lebih bervariasi, dan inputan sampel bisa berupa citra Al-Qur’an selain dari surat Al-Baqarah. Walaupun begitu, sistem deteksi Tajwid ini tidak menafikan pentingnya guru untuk membimbing dalam belajar cara baca sesuai dengan hukum-hukum Tajwid yang benar.

Published: October 2018

Graphene is one of the best conductive materials for developing nanocomposites due to its outstanding electronic properties. Graphene is developed by modified Hummers’ method. Zinc oxide (ZnO) based composites were developed by using different weight percentages (0.1%, 0.5% and 1%) as reinforcement. To enhance the dispersion of graphene in ZnO matrix the synthesis was processed by ultrasonication process. The obtained graphene oxide, ZnO and composites were characterized by X-ray diffractometer (XRD), Fourier transform infrared spectroscopy (FTIR) and field emission scanning electron microscopy (FESEM) techniques for structural information, band analysis and surface morphology respectively. The proposed nanocomposites were developed by varying loading percentages 0.1%, 0.5% and 1% weight of graphene. These materials are used in various applications like varistors, energy storage, sensors, super capacitors and so on.
“Cuando consumo me siento menos triste”: exclusión y dificultades de adaptación social escolar (DASE) en estudiantes con consumo problemático de alcohol y drogas

Published: October 2018

Resumen:El presente estudio consiste en reconstruir los itinerarios escolares de un grupo de estudiantes de liceos municipalizados de la ciudad de Puerto Montt, Chile, consumidores frecuentes de alcohol y/o drogas. Por medio del análisis etnográfico y la revisión hermenéutica de documentos institucionales, realizados en el contexto escolar, proponemos la nomenclatura de Dificultades de Adaptación Social Escolar (DASE) para referirnos a aquellos estudiantes que fracasan en su paso por los centros educativos formales, debido a su escaso capital social y cultural, pero también a la poca o nula atención prestada por los propios centros a aquellos jóvenes que presentan complejidades adaptativas en el marco de la cultura escolar. Igualmente, proponemos que las DASE necesitan de una atención especializada con educadores formados para dicho propósito. Abstract:The present study consists in reconstructing the school itineraries of a group of students of public high schools in the Puerto Montt city, Chile, frequent consumers of alcohol and / or drugs. Through the ethnographic analysis and the hermeneutical revision of institutional documents, carried out in the school context, we propose the nomenclature of School Social Adaptation Difficulties (SSAD) to refer to those students who fail in their passage through formal education centers, due to their Low social and cultural capital, but also to the little or no attention given by the centers themselves to those young people who present adaptive complexities within the framework of the school culture. Likewise, we propose that the DASE need specialized attention with educators trained for this purpose.

The Effects of the Expansion of For-Profit Colleges on Student Enrollments and Outcomes at Community Colleges
Authors: Soliz Adela
Published: October 2018

This study is the first large-scale examination of the impact of for-profit colleges on the enrollment and outcomes of students at other postsecondary institutions. Using data primarily from the Integrated Postsecondary Education Data System (IPEDS) and a differences-in-differences approach, I estimate the effect of a new for-profit college opening on community college enrollments and degree completions, as well as county education levels. My results suggest that community college enrollments and degree completions do not decline when a new degree-granting for-profit college opens nearby. Furthermore, I find evidence that the county-level production of short- and long-term certificates increases after a new for-profit college opens, though the number of associate’s degrees does not increase. This evidence should serve to broaden conversations about the role of for-profit colleges in the larger landscape of the American higher education system.

Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation method that is frequently used to study cortical excitability changes and their impact on cognitive functions in humans. While most stimulators are capable of operating in double-blind mode, the amount of discomfort experienced during tDCS may break blinding. Therefore, specifically designed sham stimulation protocols are being used. The "fade-in, short-stimulation, fade-out" (FSF) protocol has been used in hundreds of studies and is commonly believed to be indistinguishable from real stimulation applied at 1 mA for 20 minutes. We analyzed subjective reports of 192 volunteers, who either received real tDCS (n=96) or FSF tDCS (n=96). Participants reported more discomfort for real tDCS and correctly guessed the condition above chance-level. These findings indicate that FSF does not ensure complete blinding and that better active sham protocols are needed.

Published: October 2018

Pojava novih psihoaktivnih tvari u Hrvatskoj počela je zaokupljati pažnju javnosti tek nedavno, iako je nacionalni Sustav ranog upozoravanja u slučaju pojave novih psihoaktivnih tvari ustrojen još 2007. godine. Prepoznavanju problema od strane javnosti pridonijela su izvješća o trovanjima i smrtnim slučajevima povezanim s konzumiranjem takvih tvari u državama članicama Europske unije, kao i njihova rastuća dostupnost u specijaliziranim trgovinama (tzv. smart shop) i na Internetu. U ovom radu prikazat će se utvrđivanje programa politike novih psihoaktivnih tvari u Hrvatskoj, pri čemu će se primijeniti fazni model procesa stvaranja javnih politika, odnosno, model ciklusa javnih politika. Utvrđivanje programa javnih politika predstavlja početnu fazu procesa, stoga je svrha rada raspraviti aktivnosti, okolnosti i aktere koji su važni za postavljanje politike suzbijanja zlouporabe novih psihoaktivnih tvari na program političkog odlučivanja.

Follow the journey of this ‘being’ as they use futurity devices to walk to the flash mob futurity cypher, a radical project of joy and love, summoning Black and Indigenous folx to dance for the future.
Montreal’s Maple Spring: The Afterlives of Movement Histories
Authors: Miller Stefanie Ellen
Published: October 2018

In the spring and summer of 2012, thousands gathered in the streets of Montreal each night to bang on pots and pans to protest a law intended to subdue striking postsecondary students by stipulating how, when, and where bodies could assemble in public space. Six years later, this article reflects on the choreographic afterlives of the Maple Spring, examining how protestors enact gestural ‘movement histories’ that connect individuals with broader social bodies of the past, present, and future.
Some People Are Oil and Water
Authors: McNab Brynn Catherine
Published: October 2018

This essay addresses the Trans Mountain Pipeline Expansion project and its ensuing political turmoil as an expanded assembly of performative processes. Bringing contemporary media theory’s examinations of the composition of an apparatus or “dispositif” to bear on recent developments in vitalist materialism, this essay argues for the inclusion of non-human material elements in the political sphere. In particular, it defines the tendencies of contention between oil and water as a fundamental antagonism within these elemental materials. This study is grounded in the public performances of provincial, federal, and municipal governments as they relate to processes of control and resistance. In its analysis of current rhetoric surrounding the project, including political performances, this essay aims to redefine the conflict over resource extraction and pipeline development through a strategy of resistance that figures oil and water as political actants in an expanded choreographic assembly.

Toronto, English-Canada, and the ‘ROC’: Robert Lepage Onstage
Authors: Carolan Claire
Published: October 2018

This is a review of Jane Koustas’s 2016 book Robert Lepage on the Toronto Stage: Language, Identity, Nation. The reviewer comments on Koustas’s inquiry into Lepage’s success on the Toronto stage, his contribution to global perceptions of Canadian theatre, and his identity as a critically acclaimed artist in English Canada. The review queries the author’s identification of Toronto as the de facto representative of the ROC (Rest of Canada) and the ways that the book’s formatting of lengthy French passages replicates how audiences experience bilingual performance. The review suggests that, like many of Lepage’s works, Koustas’s book raises questions it leaves unanswered and points out productive areas for further inquiry.

This article reviews Barry Freeman’s 2017 book, Staging Strangers: Theatre and Global Ethics. With precision and intellect, Freeman layers multiple theoretical frameworks to examine Canadian theatre, predominantly focusing on performance in Toronto. Freeman fruitfully explores how the definition and production of who is a stranger on Canadian stages is contextually contingent and changes over time, as well as the ways in which it is a construct of complex power relations in society regarding nationalism, multiculturalism, and globalization. This book is a significant contribution to the study of theatre in Canada that combines complicated theories with practice and provides illustrative examples to explore the ways in which theatre can ethically encounter difference in an age of ‘liquid modernity.’

Kurzfassung

Die fortschreitende Digitalisierung wird Unternehmen in Zukunft massiv verändern. Bislang existieren lediglich punktuell umgesetzte Beispiele für sog. Smart Factories und diese sind eher (informations-)technisch geprägt. Das Unternehmen Phoenix Contact hat sich daher entschlossen, die digitale Transformation in Richtung Smart Factory mit einem eigenen Konzept zu bearbeiten. Unter Beteiligung betroffener Führungskräfte, weiterer Unterstützungsfunktionen aus dem Unternehmen und dem Betriebsrat ist zunächst ein Zukunftsbild für eine Smart Factory erarbeitet worden, für das dann – auf Grundlage der wesentlichen künftigen Prozesse – eine passende Aufbauorganisation ausgewählt wurde. Auf dieser Basis können nun alle Beteiligten gezielt für die neuen Arbeitsaufgaben qualifiziert werden; zudem lassen sich in weiteren Schritten technologische Konzepte auswählen und sinnvoll integrieren. In diesem Beitrag wird das Projekt „SmartOrg@Combicon“, als Initialisierungsphase im Rahmen der Umsetzung einer Smart Factory, dargestellt.

Topicality. The urgency of the problem of state incentives for the sustainable development of regions on the basis of economic freedom, property, rule of law and democracy is increasing in today's conditions of strengthening the role of such factors as globalization, competitiveness and innovation in the world.
Aim and tasks. The purpose of the article is to study theoretical, methodological and practical recommendations, which should justify the tools for improving the state incentives for the sustainable development of regions in Ukraine and Poland, taking into account the experience gained from the European Union countries.
Research results. Research and practice show that the development and rates of economic growth in the country depend on the efficiency of public institutions. They are one of the most important variables that explain the differences in the rates of economic growth in the groups of developing and transforming countries. It was found that the decentralization of state functions means that it delegates its powers to the structures it establishes, one of which is a region with, inter alia, administrative rights. Therefore, the article provides a comparative analysis of the legal conditions for the sustainable development of the regions in the EU, Poland and Ukraine. It should be noted that both the basis for smart development and inclusive development are important, however, this study focuses on the components of sustainable development, and, therefore, the stimulation of an economy that effectively uses resources, while being environmentally friendly and more competitive.
Conclusions. It was found that in all the analyzed countries, the planning documents on the regional level take into account the basic principles of the arrangement, development and land use taking into account historical, economic, ecological, demographic, ethnic and cultural features of the region. Prospects for future research in the field of state incentives for sustainable development of regions are related to the effective structure of the formation of the institutional environment of the state.

Bergenia ciliata is an essential medicinal plant used in regions where western medicines are inaccessible due to their unavailability and high cost. The methanolic extract of Bergenia ciliataroots was separated for phytochemical elements and in-vitro antioxidant activity. The plant extract showed the rich outgrowth of secondary metabolites that play the role for biological activities. The higher antioxidant functioning of the plant is due to the occurrence of reactive elements like phenols and flavonoids. The antioxidant functioning of the plant extract was measured by DPPH free radical scavenging assay. In DPPH free radical scavenging assay the IC50 value of Bergenia ciliata was found to be 11.21μg/mL, while the IC50 value of standard ascorbic acid was found to be 45.93μg/mL

Authors: Ivanov P. S. , Plyaskin A. S.
Published: October 2018

One of the directions of further building development and improvement is the creation of structures with a complex internal structure, i. e. combined sections made of various materials operating in a single construction. It is necessary to search for new engineering methods that take into account the behavior of such structures. Trigonometric functions of in ertia moments not only increase the efficiency of computations, especially for complex resistance, but also provide new approaches to the development of engineering methods of building calculation with a complex internal structure.

Objective: The aim of this work is to increase the calculation range for formulas of determining the ratios of inertia moments based on the transformation of trigonometric functions.

Results: A new application of inertia ratios is proposed for the use of trigonometric functions.

Practical implications: The results of theoretical studies can be used in the development of engineering methods for building calculations with a complex internal structure.

The paper presents the results of theoretical and experimental studies of thermal plasma heating and melting of agglomerated powder based on quartz sand screenings of the Tugan Deposit, Tomsk region, Russia. It is shown that phase transitions significantly affect the process of thermal plasma heating and melting of agglomerated powder, which can lead to unjustified heating of particles. The results of thermochemical processes due to heating are presented herein. It is found that the total concentration of phases subjected to evaporation at the initial stage, is rather small (0.13 wt.%). The model is proposed for the hollow particle formation from silicon dioxide agglomerates.

The paper reviews the most significant objects of historical and cultural heritage, built to the order of the Kukhterins in the 19–20th centuries in the city of Tomsk. The architectural analysis of individual buildings illustrated by historical and modern photographs, archival and graphic materials, is performed. It is shown that owing to the Kukhterins and Lygin cooperation, bright public objects appeared in Tomsk. They possess memorable images and reflect the merchant approach to construction - qualitative, practical and beautiful.
Kontrol Kaybı Kaygısı ve Kontrol Edilemeyen PanikBozukluk: Bir Vaka Örneği
Authors: ÖNCÜL Öznur
Published: October 2018

Panik bozukluğun, “kontrol kaybından duyulan endişe”, “mükemmelliyetçilik” ve “kaçınmacı başetme stratejileri” gibi faktörlerle ilişki içerisinde olduğu literatürde sıklıkla vurgulanmaktadır. Bu özelliklerin panik bozukluğun ortaya çıkmasında nasıl etkili olduklarının ve nasıl bir mekanizma içerisinde bir araya geldiklerinin anlaşılması, rahatsızlığın yeniden ortaya çıkmasını önlemeye yönelik terapötik müdahalelerin etkililiğini arttıracaktır. Kimi çalışmalar, panik bozukluk etiyolojisinde kaçınmacı ya da obsesif-kompülsif kişilik özelliklerinin yer alabileceğinden söz etse de bu özelliklerle panik bozukluk arasında nedensel bir bağlantı kurmaya yönelik açıklamalara nadiren rastlanılmaktadır. Genellikle psikodinamik kuram çerçevesinde yapılan bu açıklamalar ise, kişinin, karşılanamayan bağımlı olma ihtiyaçları ve etkili bir biçimde baş edemediği öfke duygusu sebebiyle yaşantıları üzerinde aşırı bir kontrol sağlama çabası içerisine girmiş olabileceklerini vurgulamaktadır. Bu makalede, bir panik bozukluk vakasının formüle edilmesi üzerinden, kontrol kaybı kaygısının ve diğer ilişkili faktörlerin, ebeveyne yönelik öfkenin bastırılması ve tepki oluşumu stratejisi çerçevesinde nasıl örgütlendikleri ele alınacak ve bu faktörlerin danışanın hayatında ve panik bozuk semptomlarının ortaya çıkmasında nasıl bir role sahip oldukları tartışılacaktır.

Published: October 2018

Altı temel duygudan biri olarak korkunun psikopatoloji, hasta ve terapist bakımından incelenmesi amacıyla kaleme alınan bu makalede ilk olarak korkunun tanımı ve diğer duygulardan ayrımı açıklanıp psikopatoloji literatüründe yer alan bilişsel ve psikodinamik teorilerle korkunun altında yatan mekanizmaların nasıl açıklandığı paylaşılmıştır. İkinci olarak Freud’un “Küçük Hans” vakası ve Oğuz Atay’ın “Korkuyu Beklerken” hikâyesi korkunun bireyde nasıl ortaya çıktığı ve onun hayatını nasıl etkilediği sorularına cevap bulmak amacıyla katmanlı duygu modeline göre irdelenmiştir. Son olarak, yine aynı model çerçevesinde korku duygusunun terapist açısından incelenmesini sağlamak üzere duyguların devam eden terapideki önemi, aktarım ve karşı aktarım ile bunların psikoterapideki yeri, karşı aktarımın engelleyici yanları ve karşı aktarımın yönetim yolları “Küçük Hans” ve “Tedavi (In Treatment)” dizisinde yer alan “Laura” vakası üzerinden ele alınmıştır. Yapılan bu incelemelerin hem bilişsel hem de psikodinamik teorik açıklamalara ve katmanlı duygu modeline açıklama getirip örnek teşkil etmeleri, bu makalenin akademik ve pratik alanlarda çalışan ruh sağlığı uzmanları için faydalı olacağına işaret etmektedir.

Objectives: Antibiotics are frequently used in tertiary care hospitals. We conducted an observational study on children admitted to a teaching hospital in south India, to make a profile of antibiotics use and suspected adverse drug reactions (ADRs) owing to them. Methods: Hospitalized children of either sex, aged between 1 month and 12 years, were inspected. Baseline demographic and clinical features, duration of hospital stay, antibiotics received in hospital along with dosing and indications and interest of suspected ADRs attributable to their use were recorded. Every patient was followed up till discharge, admission to the Pediatric Intensive Care Unit, or passing. Results: Over the year and a half report period 364 confirmations were screened. The prevalence of Antibiotics use was 80.22%. The majority of the 292 children who received Antibiotics were males (63.35%). Median age was 35 months, five children died. In most instances, either two (41%) or a single antibiotic (37.32%) was used. Ceftriaxone, co-amoxiclav, amikacin, vancomycin, and ampicillin were predominantly used. Antimalarials, antivirals and antiprotozoals were used occasionally. Average number of Antibiotics per patient was 2.2 ± 1.1 the majority (81.15%) were by parenteral route and initial choice was usually empirical. Prescriptions were usually in generic name. The antibiotic treatment went somewhere in the range of 1 and 32 days, with a middle of 8 days. Five ADRs were noted of which half were skin rash and the rest loose stools. Conclusions: The profile of Antibiotic utilize is comprehensively like prior Indian investigations. Apparent overuse of multiple Antibiotics per prescription and the parenteral route requires exploration. Antibiotics are being used empirically in the absence of policy. ADRs to Antibiotics are occasional and usually mild. The benchmark information can serve in situation analysis for antibiotic prescribing guidelines.
