Pemanfaatan Air Asam Tambang Dalam Teknik Elektrokinetik Untuk Menurunkan Kadar Logam Berat Bahan Timbunan Bekas Tambang
Authors: Suryaningratyas D. T. , Firosya F. , Darmawan Darmawan 
Published: June 2017

Teknik elektrokinetik merupakan salah satu teknik remediasi tanah atau bahan lain yang terkontaminasi logam berat. Teknik ini dikembangkan terutama untuk mengatasi lokasi-lokasi yang terkontaminasi logam berat dalam level yang cukup tinggi. Prinsip dasar teknik ini adalah dengan memberikan arus searah pada bahan yang terkontaminasi dengan menggunakan elektroda (katoda dan anoda) pada tegangan rendah. Penggunaan air asam tambang (AAT) sebagai larutan elektrolit pada percobaan laboratorium untuk mengurangi kandungan logam berat pada bahan timbunan bekas tambang telah dilakukan. Penambahan asam cenderung meningkatkan efektivitas teknik ini. Hasil penelitian menunjukkan bahwa teknik elektrokinetik dapat digunakan untuk menurunkan kandungan logam berat (Fe, Cu, Pb, dan Mn) lebih dari 6% sampai 90% dari kandungan semula. Penggunaan air asam tambang sebagai elektrolit tidak menunjukkan hasil yang berbeda nyata dengan penggunaan air sebagai elektrolit. Akan tetapi untuk aplikasi di lapang, pemanfaatan asam tambang yang telah tersedia di daerah pertambangan akan lebih efisien digunakan dibandingkan dengan menggunakan air bersih.Kata kunci : air asam tambang, kontaminasi, logam berat, remediasi, teknik elektrokinetik
Aplikasi Adaptive Nuero-Fuzzy Interference System (ANFIS) Sebagai Soft Sensor Untuk Memprediksi Komposisi Produk Pada Kolom Distilasi
Authors: Biyanto T. R. 
Published: June 2017

Makalah ini memaparkan pemanfaatan Nuero-Fuzzy Interference System (ANFIS) sebagai soft sensor untuk memprediksi komposisi produk distilat dan produk bawah pada kolom distilasi. Model plant kolom distilasi dibangun menggunakan hysys software dengan metode shortcut dan rigorous sedangkan ANFIS menggunakan mekanisme penalaran fuzzy sugeno. Pengukuran fraksi mol pada kolom distilasi biner biasanya merupakan pengukuran secara infential. Fraksi mol dari distilat dan produk bawah diwakili oleh temperature pada bagian tertentu dari kolom distilasi tersebut. Hubungan antara temperatur dan fraksi sebenarnya non linier dan dipengaruhi oleh pengganggu-pengganggu, seperti tekanan kolom distilasi, fraksi mol feed, laju feed dan laju panas reboiler. Pada penelitian, nilai Xd mempunyai korelasi terdekat dengan temperatur pada tray 14 (top tray) dan nilai Xb mempunyai korelasi terdekat dengan temperatur pada tray 1 (bottom tray). Oleh karena itu sensor temperature diletakkan pada tray 1 dan tray 14 untuk memprediksi Xd dan Xb. ANFIS softsensor menghasilkan nilai RMSE sama dengan 2.0034 x 10-5 untuk fraksi atas dan RMSE = 1.6850 X 10-4 untuk fraksi bawah.Kata kunci : komposisi produk kolom distilasi, soft sensor, Adaptive Nuero-Fuzzy Interference System
Studi Produksi Hidrasin VIA Proses Urea
Authors: Sitompul J. P. 
Published: June 2017

The use of hydrazine,N2H4 becomes very broad nowadays, in the production of polymer such as automobile air bags, in pharmacy, and in the water treatment for oxygen scavenge. Three commercial processes are available for hydrazine production , i.e. via Rasching-Olin, Ketazin, and Urea process. The operating condition for the later process is very mild compared to with the other two processes and hence requires simple processing equipments. This paper concerns with the kinetic study on production and on the effect of deactivator/ inhibitor during hydrazine bench-scale production via Urea process. Operating condition are at 1 bar and at temperature range 5-100 0C. The yield of the hydrazine and its concentration with varying reactants, NaOH, hypochlorite, and urea during the cource of reaction are presented. Futher, the effect of gelatin as the deactivator toward hydrazine yield is futher examined. A kinetic model is proposed and used to predict yield of hydrazine. The predicted yield is in close agreement with the experimental yield.Keywords : hydrazine, bench-scale production, kinetic model, oxygen scavenger, inhibitor, geltine

Aus einer Bedarfsanalyse basierend auf Experteninterviews und Diskursanalysen lässt sich die grundsätzliche Erkenntnis festhalten, dass eine konsequente Digitalisierung des geisteswissenschaftlichen Publizierens bisher ausbleibt und sich entsprechende Entwicklungen innerhalb der Disziplinen asynchron entwickeln. Davon ausgehend formulierte das Projekt konkrete Handlungsempfehlungen jeweils für Vertreter der Geisteswissenschaften, der Informationsinfrastrukturen, der Wissenschaftspolitik und Förderinstitutionen sowie der Verlage.
Finanzierungsmodelle für Open-Access-Zeitschriften
Authors: Keller Alice 
Published: June 2017

ZusammenfassungErgebnisse aus verschiedenen Studien zeigen, dass viele Herausgeber sich bei der Gründung einer Open-Access-Zeitschrift kaum Überlegungen machen zu den möglichen Geschäftsmodellen zur Deckung der entstehenden Kosten. Bisweilen wird vergessen, dass Open Access kein Geschäftsmodell sondern ein Zugangsmodell ist. Aber auch in den Fällen, wo sich Herausgeber umfassende Überlegungen machen, fehlt der Überblick, welche Einnahmemöglichkeiten grundsätzlich für Open-Access-Publikationen zur Verfügung stehen. Oft werden Bibliotheken hier um finanzielle Hilfestellung oder Rat gebeten.Der Artikel beschreibt im ersten Teil exemplarisch verschiedene Ausgangslagen von Open-Access-Zeitschriften. Im Vordergrund der Diskussion stehen neue Einzelzeitschriften oder sogenannte „Flips“ bestehender Zeitschriften zu Open Access. Im zweiten Teil werden neun unterschiedliche Geschäftsmodelle vorgestellt. In der Schlussfolgerung wird versucht, diese exemplarischen Kategorien von Zeitschriften den Geschäftsmodellen zuzuordnen, d. h. welches Finanzierungsmodell ist für welchen Zeitschriftentyp geeignet?

Childhood Firearm Injuries in the United States
Authors: Fowler Katherine A. , Dahlberg Linda L. , Haileyesus Tadesse , Gutierrez Carmen , Bacon Sarah 
Published: June 2017

OBJECTIVES:
Examine fatal and nonfatal firearm injuries among children aged 0 to 17 in the United States, including intent, demographic characteristics, trends, state-level patterns, and circumstances.

METHODS:
Fatal injuries were examined by using data from the National Vital Statistics System and nonfatal injuries by using data from the National Electronic Injury Surveillance System. Trends from 2002 to 2014 were tested using joinpoint regression analyses. Incident characteristics and circumstances were examined by using data from the National Violent Death Reporting System.

RESULTS:
Nearly 1300 children die and 5790 are treated for gunshot wounds each year. Boys, older children, and minorities are disproportionately affected. Although unintentional firearm deaths among children declined from 2002 to 2014 and firearm homicides declined from 2007 to 2014, firearm suicides decreased between 2002 and 2007 and then showed a significant upward trend from 2007 to 2014. Rates of firearm homicide among children are higher in many Southern states and parts of the Midwest relative to other parts of the country. Firearm suicides are more dispersed across the United States with some of the highest rates occurring in Western states. Firearm homicides of younger children often occurred in multivictim events and involved intimate partner or family conflict; older children more often died in the context of crime and violence. Firearm suicides were often precipitated by situational and relationship problems. The shooter playing with a gun was the most common circumstance surrounding unintentional firearm deaths of both younger and older children.

CONCLUSIONS:
Firearm injuries are an important public health problem, contributing substantially to premature death and disability of children. Understanding their nature and impact is a first step toward prevention.
Protein kinase C (PKC) involved in enhancement of α1-adrenoceptor-mediated responses of the main pulmonary artery in rats with diabetes mellitus

Published: June 2017

Diabetes mellitus (DM) causes multiple dysfunctions including circulatory disorders such as cardiomyopathy, angiopathy, atherosclerosis and arterial hypertension. Moreover, DM can strongly affect pulmonary circulation, enhancing the wall thickness of the pulmonary arteries, changing their tone and contractility, and gas exchange in the lungs. It can lead to marked loss of lung function and respiratory efficiency. It is also known that protein kinase C (PKC) activity increases in DM and that PKC is involved in the mechanisms of DM-associated vascular complications. However, the effect of DM on pulmonary artery tone has been poorly investigated and the role of PKC in this remains unknown. The aim of this study was to investigate changes in contractility of pulmonary arteries in rats with DM and to determine the possible role of PKC in this process. Experimental type 1 DM was elicited in male Wistar rats by single streptozotocin (STZ, 65 mg/kg) injection. DM was verified by the presence of hyperglycaemia. The investigation was performed on the isolated rings of the main pulmonary arteries using the method of vascular tone registration. Phenylephrine (PhE, 0.1 nM – 1 mM) caused dose-dependent constriction of the pulmonary arteries. The pD2 (negative logarithm of the agonist concentration required for half-maximum response) of this constriction increased in rats with DM, however significant changes in amplitude of PhE-induced constriction were not observed. PKC inhibition with chelerythrine and staurosporine (1 µM) significantly shifted PhE the concentration-response curve to the right in intact diabetic vessels but had no effect on sensitivity to PhE in deendothelised diabetic vessels. Our data suggest that type 1 DM leads to enhancement in pulmonary artery α1-adrenoceptor-mediated contractility and PKC activity in the endothelium rather than in vascular SMCs is involved in this process.

Authors: Hatzidakis Adam , Galanakis Nikolaos , Kehagias Elias , Samonakis Dimitrios , Koulentaki Mairi , Matrella Erminia , Tsetis Dimitrios 
Published: June 2017

Background and aims
Budd–Chiari syndrome (BCS) is treated with anticoagulation therapy, transjugular intrahepatic portosystemic shunt (TIPS), angioplasty, and liver transplantation. TIPS is not always technically feasible, due to the complete hepatic venous thrombosis. Direct intrahepatic portosystemic shunt (DIPS) is an alternative method for decompression of portal hypertension. This is a retrospective, single-center study aiming to evaluate the outcome of ultrasound (US)-guided DIPS in patients with BCS.

Materials and methods
Between 2003 and 2016, six patients with BCS were treated with US-guided DIPS. Polytetrafluoroethylene (PTFE)-covered stents were used in two patients and bare-metal stents in four patients. Mean follow-up time was 71.4 months (range: 21–164). Technical/clinical success, technical difficulties, and complications of DIPS were analyzed.

Results
Technical success without complications was achieved in all patients (100%). In one patient, DIPS was performed through the right femoral vein, without significant amelioration of portal hypertension (clinical success 83.3%). In four out of five patients, ascites and variceal bleeding resolved completely and in the other one ascites was relieved. Six- and 12-month primary patency rates were 100% in PTFE-covered stent group when compared with bare-metal stent group, the rates were 33% and 0%, respectively.

Conclusion
US-guided DIPS is a safe and effective alternative technique for patients with BCS, with significant clinical improvement.

Abstract: Introduction: Lung cancer is a rapidly progressing, often life-threatening disease that constitutes a huge societal burden. Because of the scarce resources of the Hungarian health care system, the cost-effectiveness of introducing low-dose computed tomography screening is a relevant health policy matter. Aim: The aim of this study is to design a model concept for assessing the cost-effectiveness of low-dose computed tomography lung cancer screening in Hungary, and to define the required steps for performing the analysis. Method: A targeted literature review was conducted to identify and synthesize the evidence on efficacy and effectiveness of screening, and results were evaluated based on adaptability to Hungarian settings. We also summarized the available Hungarian scientific evidence and reconstructed the potential patient pathways. Results: In accordance with these findings, we recommend to perform the full health-economic evaluation of low-dose computed tomography lung cancer screening using a complex model structure that consists of several sub-models and is capable to follow the population at risk on life-time horizon. Conclusions: The proposed cost-effectiveness model will be suitable to provide data for further analyses that support decision-making on introducing low-dose computed tomography lung cancer screening as public health program.

Published: June 2017

Abstract: Introduction: Preterm children’ development and harmful affecting factors to development are important aspects of public health, because in our country the number of preterm birth is very high. Aim: Description of psychomotor development of preterm children (Brunet-Lézine; Bayley-III) and connection between psychomotor development and maternal abuse history (own questionnaire). Method: Extremely (<1000 g) and very low (1000–1500 g) birth weight preterm children at 23–30 months (n = 35) and their mothers’ abuse history were measured. Results: Lower birth weight was associated with lower psychomotor development quotients and higher development risk. Strong associations were found between maternal history of childhood abuse and the development quotients. Conclusions: We would like to draw attention to the importance of assessing preterm children, as well as to the importance of maltreatment and the severity of its consequences. With the early recognition of necessity for developmental interventions we can prevent problems in the future. Orv Hetil. 2017; 158(25): 976–983.
Трансформация женской образности в советском кинематографе 1920–1930-х гг.

Published: June 2017

<p>В статье представлено исследование динамики трансформации женских типов образов и их художественной репрезентации в кинематографе как отражение изменений в социально-политической истории России. Хронологические рамки исследования — 1920–1930-е гг.</p><p>В постреволюционной России женский мир подвергся коренной перестройке. Изменения в социальном положении женщин обусловили появление образа новой женщины как воплощения прав и свобод новой Советской России. Основные женские типы — героический, материнский и роковой — изменяются и обновляются, формируясь в систему мифов-идеологем и репрезентуются в массовой культуре.</p><p>Проанализированы доминирующие в каждом десятилетии типы и особенности их эволюции под влиянием социокультурных и идеологических факторов. Через анализ киноматериала выявляются мифосемиотические основы функционирования и визуализации героинь советского кинематографа и их неомифологическая характеристика.</p><p>Анализ показывает, что доминирующим женским типом в 1920-х годах становится героический, синтезировавший в себе новую символику и реанимацию мифологических моделей и схем. В 1930-е на фоне трансформации героики из революционной в производительную актуализируется материнский тип, связанный с архетипом Родины-матери, и два доминирующих типа сливаются, образуя синтетический образ, на основе которого формируется специфический тип советской женщины.</p>
Половая мораль московских студентов: религиозный аспект
Authors: Тихомиров Дмитрий Андреевич 
Published: June 2017

<p>В статье на основании результатов проведенного автором в 2016 г. эмпирического исследования рассматривается влияние религии на семейно-брачные ценности и нормы московских студентов, причисляющих себя к последователям той или иной религии. Проводится дифференциация отношения религиозных (православных и мусульман), нерелигиозных и неверующих студентов к многодетности, добрачному целомудрию, сожительству, разводу, супружеским изменам, однополым бракам. Восприятие этих явлений различается как между религиозными, нерелигиозными и неверующими группами, так и внутри религиозной группы. Наиболее выражены традиционные взгляды на семью и половую мораль у религиозных студентов, наименее — у неверующих. Среди религиозных студентов мусульмане занимают более традиционную позицию в вопросах половой морали, нежели православные, за исключением группы воцерковленных, но ее численность незначительна (4% от всех православных). Автор показывает, что отношение к обозначенным выше аспектам семейно-брачной сферы как норме или отклонению определяется не только религиозной принадлежностью, но и уровнем религиозности молодежи. Однако в целом для православных, хотя и в гораздо меньшей степени, чем для нерелигиозных и неверующих студентов, характерна деструкция нормативности в различных вопросах половой морали.</p><p>Либерализация половой морали в России практически не затронула сферу нетрадиционных сексуальных отношений. Большинство московских студентов, особенно религиозных, воспринимают однополую любовь как ярко выраженное отклонение. </p>
