Abstract

BACKGROUND
Heart failure (HF) is a leading cause of morbidity and mortality worldwide. Plasma concentrations of B-type natriuretic peptide (BNP) or its amino terminal congener (NT-proBNP) are used for HF diagnosis and risk stratification. Because BNP concentrations are inexplicably lowered in obese patients, we investigated the relationship between proBNP glycosylation, plasma NT-proBNP, and body mass index (BMI) in HF patients.

METHODS
Three assays were developed to distinguish between total proBNP (glycosylated plus nonglycosylated proBNP), proBNP not glycosylated at threonine 71 (NG-T71), and proBNP not glycosylated in the central region (NG-C). Intraassay and interassay CVs were &lt;15%; limits of detection were &lt;21 ng/L; and samples diluted in parallel.

RESULT
Applying these assays and an NT-proBNP assay to plasma samples from 106 healthy volunteers and 238 HF patients determined that concentrations [median (interquartile range)] of proBNP, NG-T71, and NT-proBNP were greater in HF patients compared with controls [300 (44–664), 114 (18–254), and 179 (880–3459) ng/L vs 36 (18–229), 36 (18–175), and 40 (17–68) ng/L, respectively; all P &lt; 0.012]. NG-C was undetectable in most samples. ProBNP concentrations in HF patients with BMI more or less than 30 kg/m2 were not different (P = 0.85), whereas HF patients with BMI &gt;30 kg/m2 had lower NT-proBNP and NG-T71 concentrations (P &lt; 0.003) and higher proBNP/NT-proBNP and proBNP/NG-T71 ratios (P = 0.001 and P = 0.02, respectively) than those with BMI &lt;30 kg/m2.

CONCLUSIONS
Increased BMI is associated with decreased concentrations of proBNP not glycosylated at T71. Decreased proBNP substrate amenable to processing could partially explain the lower NT-proBNP and BNP concentrations observed in obese individuals, including those presenting with HF.

Authors: Schneider Craig W. , Wynne Michael J. 
Published: May 2019

Abstract
The fourth addendum to Schneider and Wynne’s 2007 “A synoptic review of the classification of red algal genera a half century after Kylin’s 1956 ‘Die Gattungen der Rhodophyceen’” is presented, covering the names of genus- and higher-level taxa added or modified since our third addendum (Bot. Mar. 59: 397–404). Since that synopsis, we added 21 new genera in a first addendum, 27 in the second, and 40 in the third, demonstrating the increasing amount of genetic work over more than a decade. In this fourth addendum, we add 58 new genera to the list of red algae as well as many new taxa in the hierarchical framework over the past 3 years. Based upon molecular sequencing, other genera reinstated from synonymy studies are included.
Shared spaces, shared mind: Connecting past and present viewpoints in American Sign Language narratives
Authors: Janzen Terry 
Published: May 2019

AbstractIn American Sign Language (ASL) narratives, signers map conceptualized spaces onto actual spaces around them that can reflect physical, conceptual, and metaphorical relations among entities. Because verb tenses are not attested in ASL, a question arises: How does a signer distinguish utterances about past events from utterances within a present conversational context? In narratives, the story-teller’s past-event utterances move the story along; accompanying these will often be subjective comments on the story, evaluative statements, and the like, that are geared, in the present, to the conversational partner. This usage-based study looks at how the ASL signer integrates past and present spaces in a narrative and specifically, integrates the viewpoints associated with each. Blending past and present spaces, while a conceptual notion, is in ASL played out in utterance structure and also in the fact that signed language articulation takes place in a three-dimensional space upon which both the signer and addressee have embodied, perspectivized views. Past and present conceptual spaces both occupy the physical space of articulation, and so the blends are at once conceptual and perceivable.
Beyond ICS: How Should We Govern Complex Disasters in the United States?
Authors: Nowell Branda , Steelman Toddi 
Published: May 2019

Abstract
The complexity of large-scale disasters requires governance structures that can integrate numerous responders quickly under often chaotic conditions. Complex disasters – by definition – span multiple jurisdictions and activate numerous response functions carried out by numerous legally autonomous public, nonprofit, and private actors. The command operating structure of the Incident Command System (ICS) is a hierarchical structure used to manage complex incidents. Increasingly, complex disasters are seen as networks of multiple actors. Improving our capacity to respond to large-scale, complex disasters requires moving beyond the “hierarchy versus networks” debate to understand the conditions under which governance structures can best serve disaster response goals. Understanding the capabilities and limitations of the governance structures embedded in our national policy tools and frameworks can enhance our ability to govern effectively in networked contexts. In this article, we suggest the need to shift focus to build greater capacity for hybrid and network governance approaches, including a more sophisticated understanding of the conditions under which these governance forms are most effective.

Abstract
This research focuses on the side-polished Single-Mode Optical Fibers (SMOF) as refractive index (RI) sensor utilizing properties of Surface Plasmon Resonance. The SMOF with cladding stripped off shows a D-shaped optical fiber with high sensitivity functionalization. Here we show silver protected by graphene oxide (GO) as viable candidates. A few layers of GO on top of silver thin layer were applied as a material to overcome silver coating degradation process. This silver/GO sensor was characterized using various RIs of analyte likely deionized water and alcohol solutions. Sensor with GO has shown fast response and high sensitivity in respect of RI, where sensitivity increases in range from 1.30 to 1.34 RIU (refractive index unit). This device shows highest sensitivity of up to 833.33 nm/ RIU. The polishing process using SMOF stops at few microns above the core of the fiber with the drop of output power fixed to be 1 dB as an indication to standardize the amount of cladding been removed. The thickness of 30 nm Ag was deposited using electron beam evaporation method on D-shaped optical fiber with subsequent protected layer of GO in solutions form. The use of COMSOL Multiphysics has also been carried out to observe numerical findings. The response of the GO has shown a sensitivity improvement which proves new promising approaches for the newly developed sensors.

Published: May 2019

Abstract

Objective
To assess the effect of fetal gender in small-for-gestational age (SGA) neonates with birth weight less than the fifth percentile by gestational age.

Methods
We compared male and female SGA neonates for maternal and neonatal outcomes in the following gestational age subgroups: at <32 + 6, 33 + 0–36 + 6 and at ≥37 + 0 weeks of gestation.

Results
We examined 159, 154 and 2363 SGA neonates born at <32 + 6, 33 + 0 to 36 + 6 and ≥37 weeks of pregnancy, respectively, whose birth weight was below the fifth percentile for gestational age and who met our inclusion criteria. Overall, there were no significant differences between the mothers of males and females, except that there were more males at term and the incidence of nulliparas was greater among the mothers of males. In terms of outcomes, males had a similar incidence of respiratory distress syndrome (RDS), intraventricular hemorrhage (IVH) and admissions to intensive care. Interestingly, low Apgar scores were more common in preterm females born at 33–37 weeks and vice versa in births over 37 weeks.

Conclusion
Our data do not support an advantage of either gender in preterm birth of infants who are most likely growth restricted.
Zwei gegensätzliche Formen sozialer Unsicherheit aus psychotherapeutischer Sicht
Authors: Gödde Günter 
Published: May 2019

Abstract
Den Ausgangspunkt dieses Beitrags bilden die psychotherapeutischen Erfahrungen mit zwei gleichaltrigen Studenten, die zu Anfang der Therapie eine ähnlich wirkende „Unsicherheit“ zeigten. Im fortlaufenden therapeutischen Prozess kristallisierten sich aber immer stärkere Unterschiede zwischen ihnen heraus. Der eine Patient, der als „selbstunsicher“ eingeschätzt werden kann, war stark auf sich selbst bezogen und suchte seine soziale Ängstlichkeit mit einer Einzelgänger-Strategie und entsprechender Vermeidung von näheren sozialen Kontakten zu bewältigen, wobei er mit Situationen des Alleinseins und den Anforderungen selbstbestimmten Arbeitens gut zurecht kam. Der andere war beim Arbeiten und Alleinsein von der emotionalen Präsenz anderer und deren Strukturierungshilfen „abhängig“; von seinem Auftreten, seiner gefühlsmäßigen Zugewandtheit und sozialen Bezogenheit her gesehen ließ er aber hohe soziale Kompetenzen erkennen, so dass man bei ihm von einem „aktiv-dependenten“ Beziehungsmuster sprechen kann. Der Vergleich zwischen beiden Formen sozialer Unsicherheit lässt sich mit dem anthropologischen Konzept der „Bipolarität zwischen selbst- und objektbezogenen Tendenzen“ (Mentzos) in Verbindung bringen.
Überempfindlichkeit

Abstract
Dieser Beitrag erkundet die auditiven Aspekte der Unsicherheit anhand von kleinsten Wahrnehmungen, die eine durchschlagend verunsichernde Wirkung haben können. Ausgehend von einem Hörstück des Sprechkünstlers Carlfriedrich Claus und den Irritationen, die hieraus sich ergeben können, werden körperliche Idiosynkrasien als „Tätowierungen“ (nach Michel Serres) diskutiert und das historische Konzept der „petites perceptions“ (nach Gottfried Wilhelm Leibniz) vorgestellt sowie auf aktuelle Beispiele angewendet. Schließlich wird die Wirkung kleinster Wahrnehmungen auf die Bedeutung der Körperorgane des Gleichgewichts zurückgeführt und anhand zweier Beispiele (Otolith und Muskelspindel) näher betrachtet. Der Beitrag endet mit einem Lob der Idiosynkrasie, die als anthropologisch generative Eigenschaft bewertet werden könnte.
Künstlerische Praktiken des Ver(un)sicherns
Authors: Klein Gabriele 
Published: May 2019

Abstract
Unsicherheit ist ein Thema, das in der Soziologie und der Tanzwissenschaft vielfach diskutiert wird. Ausgehend von den Positionen dieser beiden Wissenschaftsdisziplinen will der Text das Thema Un-Sicherheit aus einer praxeologischen Perspektive beleuchten. Nicht die Frage „Was ist Unsicherheit?“ sondern „Wie erfolgt das Verunsichern?“ steht dabei im Mittelpunkt. Im ästhetischen Verunsichern, so soll anschließend aufgezeigt werden, liegt ein produktives Element: Das Verunsichern eröffnet Möglichkeitsräume eines erneuten Versicherns. Am Beispiel der künstlerischen Arbeit von Pina Bausch und dem Tanztheater Wuppertal wird aufgezeigt, wie sich künstlerische Praktiken des Ver(un)sicherns zu dem alltäglichen Sicherheitsempfinden, zu habituellen Dispositionen und routinisierten Praktiken verhalten.

Published: May 2019

Abstract
Drug delivery systems based upon the blending of Arabic gum and poly(N-vinylpyrrolidone) (AG/PVP) were prepared for the controlled release of acebutolol (Acb) hydrochloride. The prepared blends containing Acb were characterized using different techniques. The presence of physical interactions between the drug and polymer matrices was observed with Fourier-transform infrared spectroscopy. These interactions resulted in the transition of the drug from a crystalline to an amorphous state into the polymeric matrices, as demonstrated by differential scanning calorimetry and X-ray diffraction analysis. The thermogravimetric analysis study confirmed the presence of these interactions, which had a stabilizing effect on the drug against both thermal degradation and crystallinity. The in vitro release of Acb from the AG/PVP polymer system was investigated. Each drug-loaded system was used in a tablet formulation. Moreover, an in vitro dissolution study was carried out in three different dissolution media, and comparison of the dissolution profiles of the different dosage forms revealed that the polymer blend matrix had a better release-retarding efficiency. To better understand the release mechanism, the dissolution data were fitted to various release kinetic models.
CFD Study of Combined Impingement and Film Cooling Flow on the Internal Surface Temperature Distribution of a Vane
Authors: Pujari Arun Kumar 
Published: May 2019

Abstract
Conjugate heat transfer analysis is carried out on the internal surface of the first-stage nozzle guide vane of a gas turbine, which has both impingement and film cooling holes. The mainstream flow Reynolds number and internal coolant flow Reynolds number systematically changed and its effect on internal local surface temperature variation is studied. It is found that an increase in the coolant mass flow rate causes a non-uniform decrease in the local internal surface temperature. The external film coolant jet-lift off and internal impingement cross-flow are significant contributors to the non-uniform variation in surface temperature. It is also observed that the leading edge regions are prone to jet lift-off, whereas the tip regions of the suction surface are prone to self-induced cross-flow, due to which hot patches are formed in these regions. Hot patches are observed near the hub regions of a pressure surface due to the reduced film thickness on the external surface. From these observations it is concluded that local values of internal surface temperature are differently affected in different regions of the vane surface for a given combination of mainstream and coolant flow rates. Therefore, the conventional method of obtaining the internal temperature distributions by considering generalized geometries may not yield accurate solutions, in predicting the life of the nozzle guide vane.

Abstract
Removal of volatile organic compounds (VOCs) from indoor or outdoor environments is an urgent challenge for the protection of human populations. Inorganic sorbents such as zeolites are a promising solution to tackle this issue. Using dispersion corrected periodic DFT calculations, we have studied the interaction between sodium-exchanged faujasite zeolite and a large set of VOCs including aromatics, oxygenates and chlorinated compounds. The computed interaction energies range from about −25 (methane) to −130 kJ/mol (styrene). Methane is by far the less interacting specie with the NaY zeolite. All other VOCs present interaction energies higher in absolute value than 69 kJ/mol. Most of them show a similar adsorption strength, between −70 and −100 kJ/mol. While the electrostatic interactions are important in the case of oxygenates and acrylonitrile, van der Waals interactions predominate in hydrocarbons and chlorides. By monitoring the variation of molecular bond lengths of the different VOCs before and after adsorption, we have then evaluated the tendency of adsorbate to react and form by-products, since a significant stretching would evidently lead to the activation of the bond. While hydrocarbons, tetrachloroethylene and acrylonitrile seem to be not activated upon adsorption, all oxygenates and 1,1,2-trichloroethane could possibly react once adsorbed.
A Study on the One-Dimensional Flood Numerical Analysis Method in Open Channels of Cascade Barrage Network

Published: May 2019

Abstract
Flood propagation in a river that has a network of cascade barrages is greatly influenced by the operation of the barrage floodgates that are upstream and downstream in the river. In this article, an effective flood numerical analysis method is proposed for evaluating the flood propagation process in the open channels under the complex real-time operation of floodgates at cascade barrages. The proposed model mainly uses the one-dimensional Saint-Venant equation (SVE), which incorporates upstream and downstream boundary process techniques that reflect real-time operation of floodgates and techniques for treatment of inner boundaries, such as flow of tributaries and confluence points. The real-time operation of floodgates includes the full open and partial open of floodgate in consideration of lift capacity of the crane according to time and automatic operation of floodgates for the optimal discharge considering influence of high tide and low tide. The proposed method has been validated by experiments in the Taedong River in the Democratic People’s Republic of Korea, in which six barrages from upstream and downstream in this river are taken into account. Employing the proposed method, flood routing in the channels between barrages is analyzed during the period of flooding. The validation result demonstrates that the proposed method can successfully solve the problems that arise in the analysis of flood propagation in channels of the barrage network.
Nanoporous Oxide Surface Obtained on Titanium (Grade 5) Alloy to Analyze Surface Hardness and Anti-Wear Character
Authors: Kumar Anil , Kushwaha Manoj Kumar 
Published: May 2019

Abstract
This research work exhibits a technique to enhance the surface character of nanoporous oxide layer obtained on Ti6Al4V by an anodic oxidation method and by critically analyzing its tribological behavior along with improved surface hardness. The effects of anodizing parameters like electrolytic concentration, anodic voltage, time, current density, etc. were monitored to attain well-ordered porous oxide film on the titanium substrate. Phase analysis and the morphological survey of the anodized surface were performed by an X-Ray diffractometer and scanning electron microscopy (SEM), respectively. Phase analysis revealed that porous structure appeared at 0.4 M of sulfuric acid (H2SO4) and anodic voltage at 20 V; the phase transformation from anatase to rutile occurred at 0.5 M of H2SO4. Wear tests performed on pin-on-disc–type tribometer showed accumulated oxide layer (titanium dioxide) significantly enhanced wear-resisting strength, especially abrasive wear. Comparison between the anodized and nontreated/nonanodized surface with SEM micrographs was performed to determine the response of oxide film after wear. This work determines a large range of applications for the treated surface, especially for biomaterial.

ВІДЗНАЧЕННЯ 150-РІЧЧЯ ВІД ЧАСУ СТВОРЕННЯ “ПРОСВІТИ” В ПРИКАРПАТСЬКОМУ НАЦІОНАЛЬНОМУ УНІВЕРСИТЕТІ ім. В. СТЕФАНИКА

Published: May 2019

13 грудня 2018 року в ДВНЗ “Прикарпатський національний університет імені Василя Стефаника” відбулася Всеукраїнська наукова конференція, присвячена 150-річчю від часу створення “Просвіти”. Вона була організована Івано-Франківським обласним об’єднанням ВУТ “Просвіта” та кафедрою історії України і методики викладання історії Прикарпатського університету при підтримці Івано-Франківської обласної держадміністрації, Івано-Франківської обласної ради, Івано-Франківської обласної організації Національної спілки краєзнавців України. Історичне значення товариства “Просвіта” в національному житті українського народу важко переоцінити. Вона виникла 8 грудня 1868 р. у Львові в умовах бездержавного існування українців, що перебували під владою двох імперій – Романових і Габсбургів. Імперська влада здавалася непорушною, а простий народ в абсолютній більшості був неписьменним. Майбутнє русинів-українців як окремого народу, відмінного від поляків і росіян-“великоросів”, могло виглядати для багатьох сучасників практично безнадійним. Політичну ситуацію влучно передав поетичним словом російський письменник українського походження (його нащадки були запорізькі козаки, що після заборони Січі переселилися на Кубань) Володимир Гіляровський у 1886 р.:

В России две напасти
Внизу власть тьмы,
А наверху – тьма власти.

Цей вірш-експромт стосувався Російської імперії, але схожа ситуація в ХІХ ст. була в Австрійській (з 1867 р. – Австро-Угорській) монархії. За умов імперської влади український народ залишався неосвіченим (рівень писемності на початок ХІХ ст. становив лише 5%), а правляча “верхівка” аж ніяк не хотіла поступатися владою. Виходило своєрідне “зачароване коло”, становище, з якого, здавалося, не було виходу. Однак тогочасна українська інтелігенція, в руслі національних рухів “недержавних народів” того часу, знайшла формулу, що принесла успіх у боротьбі за національне самоствердження. Ця формула вміщувалася в одне, але ємке слово, що дало назву новоствореній культурно-освітній організації – “Просвіта”. Щоправда, успіх в українському національному русі прийшов не відразу, це був шлях копіткої, наполегливої роботи освічених верств населення серед простолюду. Можливість для створення і діяльності “Просвіти” дали демократичні реформи і децентралізація внутрішнього устрою в Габсбурзькій монархії в 1860–1870-х рр.
