Evaluation of factors associated with elevated newborn 17-hydroxyprogesterone levels
Authors: Anandi V. Shobi , Shaila Bhattacharyya 
Published: May 2017

AbstractBackground:Measurement of 17-hydroxyprogesterone (17-OHP) in dried blood spots has been widely used as a newborn screening tool for congenital adrenal hyperplasia (CAH). Various maternal and neonatal factors can result in falsely high values of 17-OHP. There is a paucity of Indian studies in this regard because routine evaluation of newborn 17-OHP levels as a screening program is not widely practiced in India. Hence, this study was undertaken to evaluate the influence of various maternal and neonatal factors on newborn 17-OHP levels. The aim of the study was to determine the effect of various maternal and neonatal factors on the newborn 17-OHP values.Methods:Retrospective data related to a total of 3080 newborn 17-OHP values and clinical characteristics were collected for 3 years (2013–2015). The data were analyzed to determine the influence of various factors on 17-OHP values.Results:The mean value of 17-OHP in our study was 5.486±3.96 ng/mL. Gender and mode of delivery did not significantly affect the 17-OHP levels. The levels were significantly higher in preterm and low birth weight babies as compared to term babies and babies with normal birth weight. Stress factors like pregnancy induced hypertension (PIH), early onset sepsis (EOS), neonatal seizures and birth asphyxia significantly increase the neonatal 17-OHP levels.Conclusions:The levels of 17-OHP in newborns was measured around day 3 of life are very sensitive to the influence of gestational age, birth weight and presence of stress factors like maternal PIH, birth asphyxia, neonatal sepsis and neonatal seizures and should be interpreted cautiously.

Published: May 2017

Abstract
Knowledge of the jaguar population is needed in French Guiana that faces an increase of human-jaguar conflicts. We carried out a camera trap survey to assess jaguar local density and home range size in a preserved coastal area of French Guiana. We ran spatially explicit capture recapture (SECR) models. In our model, the scale parameter σ, that is linked to the home range size, was larger for males (σ=3.87±0.59 SE km) than for females (σ=2.33±0.30 SE km). The assessed jaguar density was 3.22±0.87 SE ind. 100 km−2, which should be considered as an optimal density in a French Guiana coastal area.

Catalysis in a dispersion medium for the hydrogenation of aromatics and hydrodearomatization in oil refining
Authors: Maximov Anton L. , Sizova Irina A. , Khadzhiev Salambek N. 
Published: May 2017

Abstract
A comparative study of nickel-tungsten sulfide catalysts for hydrodearomatization prepared in situ in a reaction medium by different methods (from a [BMPip]2Ni(WS4)2 precursor in a hydrocarbon or in an ionic liquid, from a suspension of nickel and tungsten salts formed from inverted emulsions in hydrocarbons, or from oil-soluble precursors) has been carried out. It has been found that the use of the oil-soluble precursors makes it possible to reach a high degree of sulfidizing of the active phase and a high degree of its promotion by nickel at a small size of the active phase particles. The resulting catalyst can be applied to the hydrogenation of both the naphthalene and substituted methylnaphthalenes (2-methylnaphthalene, 2,6-dimethylnaphthalene, 2,3-dimethylnaphthalene, and 2,3,6-trimethylnaphthalene) with the high selectivity for decalins and to the hydrodearomatization of light cycle oil with the complete removal of di- and polycyclic aromatic compounds.
Reaction behavior of the Collman reagent towards the nitrosyl carbonyls [CoNO(CO)3] and [Fe(NO)2(CO)2]
Authors: Böttcher Hans-Christian , Beck Wolfgang 
Published: May 2017

Abstract
Reactions of the Collman reagent, Na2[Fe(CO)4]·1.5 dioxane, towards the nitrosyl carbonyls [CoNO(CO)3] and [Fe(NO)2(CO)2] in THF as the solvent at room temperature were investigated. Thereby a quick transfer of one nitrosyl ligand from the nitrosyl carbonyl molecule to the iron carbonyl metalate was observed. The reaction with the cobalt compound afforded in high yields the well-known species [Co(CO)4]− and [FeNO(CO)3]− isolated by addition of two equivalents of [PPN]+Cl− ([PPN]+= bis(triphenylphosphane)iminium cation) and characterized by their known IR spectra, by elemental analysis and their characteristic colors and melting points. In the reaction of the Collman reagent with [Fe(NO)2(CO)2] a clean transformation to the tricarbonylnitrosylferrate(1−) as the only formed product was observed.
Topical Video Search: Analysing Video Concept Annotation through Crowdsourcing Games

Published: May 2017

Games with a purpose (GWAPs) are increasingly used in audio-visual collections as a mechanism for annotating videos through tagging. One such GWAP is Waisda?, a video labeling game where players tag streaming video and win points by reaching consensus on tags with other players. The open-ended and unconstrained manner of tagging in the fast-paced setting of the game has fundamental impact on the resulting tags. We find that Waisda? tags predominately describe visual objects and rarely refer to the topics of the videos. In this study we evaluate to what extent the tags entered by players can be regarded as topical descriptors of the video material. Moreover, we characterize the quality of the user tags as topical descriptors with the aim to detect and filter out the bad ones. Our results show that after filtering, game tags perform equally well compared to the manually crafted metadata when it comes to accessing the videos based on topic. An important consequence of this finding is that tagging games can provide a cost-effective alternative in situations when manual annotation by professionals is too costly.
R577X polymorphism of alpha-actinin-3 in human populations of North-Eastern Asia
Authors: Malyarchuk Boris A , Derenko Miroslava V , Denisova Galina A 
Published: May 2017

Background. In polymorphism rs1815739, a C T transition converts arginine to a premature stop-codon at residue 577 of the alpha-actinin-3 (ACTN3) protein (R577X polymorphism). This polymorphism may affect muscle performance, and the derived 577X allele has been found to be under-represented in sprint/power athletes. In addition, loss of alpha-actinin-3 results in a shift in muscle metabolism toward the more efficient aerobic pathway, thus pointing that this polymorphism may have been involved in enhancing the capability for hunting and for cold adaptation. Here, we study rs1815739 polymorphism in native populations (Chukchi, Koryaks and Evens) and newcomers (Russians) of North-Eastern Asia.
Materials and methods. Genomic DNA was isolated from peripheral blood. ACTN3 genotypes for rs1815739 locus were established by enzymatic digestion of amplicons with DdeI. Heterozygotes TT were confirmed by DNA sequencing. In addition, data on exome variation in Siberian populations were analyzed.
Results. Lowered frequencies (less than 40%) of mutant allele rs1815739-T were found in studied populations of North-Eastern Asia. Analysis of exome data has shown that haplotype comprising the rs1815739-T allele reaches the highest frequencies in populations of Southern and Central Siberia, while it is rather rare in the north-east of Siberia.
Conclusion. The results obtained contradict the hypothesis that the rs1815739 polymorphism may have been involved in cold adaptation of North-East Siberians.

Biomass- An Overview on Composition Characteristics and Properties
Authors: Parmar Kavita 
Published: May 2017

<em>A general overview has been proposed for biomass composition, characteristics and property. Biomass is the combination of all organic materials that simplify referring to amount of animal and plant. Biomass materials are diverse, ranging from wood, bark, straw and other agricultural residues, grasses and off-spec grains. Despite of diversity the composition of most biomass materials is relatively uniform, when moisture has been excluded. Biomass burning emission is an important part of carbon and nitrogen cycle. The pollutants released by biomass burning varies depends upon the constituents of nitrogen sulphur and carbon. In this paper basic knowledge of biomass and comparative data regarding composition and characterization has been studied. </em>
Solar-driven photocatalytic decomposition of microcystin-LR: from laboratory development to on-site demonstration
Authors: Malayeri Hesam Zamankhan , Nadagouda Mallikarjuna , Choi Hyeok 
Published: May 2017

Abstract
Harmful algal blooms (HABs) found in various water bodies worldwide have been a huge concern due to their adverse impacts on human health and ecosystems. In particular, HABs associated with cyanobacteria have been of great interest because of their potential to generate and release biological toxins, especially, lethal microcystins (MCs). The overall goal of this study was to develop a new sustainable approach to decompose MCs, preferably on-site and in real-time with minimal effort, fewer chemicals, and low energy inputs. To achieve the goal, a high efficiency nitrogen-doped TiO2 photocatalytic film immobilized onto a glass substrate was fabricated via integrated sol-gel synthesis employing nitrogen-containing surfactants as pore-templating agent and nitrogen-dopant. The film exhibited visible light-activated, nanoporous, and transparent properties. Effects of surfactant type, calcination temperature, coating layers, and reaction pH on the photocatalytic decomposition of microcystin-LR (MC-LR) were investigated under visible light. Eventually, the TiO2 film was able to successfully decompose MC-LR on-site in a lake under solar radiation in real-time. This study implies the high potential of the TiO2 film for on-site and real-time decomposition of many organic contaminants in water by using sustainable solar energy.
Laboratory Study on EOR in Offshore Oilfields by Variable Concentrations Polymer Flooding
Authors: Song Kaoping , Sun Ning , Pi Yanfu 
Published: May 2017

Background:
Polymer flooding is the most commonly applied chemical enhanced-oil-recovery technique in offshore oilfields. However, there are challenges and risks in applying the technology of polymer flooding to offshore heavy oil development.

Objective:
This paper compared the spread law and the displacement effect of different injection modes and validated the feasibility of enhancing oil recovery by variable concentrations polymer flooding.

Method:
Two types of laboratory experiments were designed by using micro etching glass models and heterogeneous artificial cores. Furthermore, in order to determine a better polymer flooding mode, the displacement results, displacement characteristic curves and oil saturation distribution of heterogeneous artificial cores were also compared, respectively.

Results:
The experimental results showed that the recovery of variable concentrations polymer flooding was higher than that of constant concentration polymer flooding, under conditions of same total amount of polymer and similar water flooding recovery. Its sweep efficiency and displacement efficiency were also significantly higher than those of constant concentration polymer flooding. Moreover, variable concentrations polymer flooding had lower peak pressure and was at lower risk for reaching the formation fracture pressure.

Conclusion:
As a consequence, variable concentrations polymer flooding has certain feasibility for heterogeneous reservoir in offshore oilfields, and can improve interlayer heterogeneity to further tapping remaining oil in medium and low permeability layer. Conclusions of this paper can provide reference for the field application of polymer flooding in offshore oilfields.

Published: May 2017

Background and objectives
Kidney length is often measured during routine abdominal ultrasonography and may be of use to identify patients at high vascular and renal risk. We aimed to explore patient characteristics related to kidney length, from which reference values were derived, and evaluate the relationship between kidney length and the risk of cardiovascular events and ESRD in high-risk patients.

Design, setting, participants, & measurements
The study population consisted of 10,251 patients with clinical manifest arterial disease or vascular risk factors included in the Second Manifestations of ARTerial disease (SMART) Study cohort between 1996 and 2014. Linear regression was used to explore patient characteristics of kidney length. The relationship between kidney length and cardiovascular events (myocardial infarction, stroke, and cardiovascular mortality), all-cause mortality, and ESRD was analyzed using Cox regression. Kidney length was analyzed in tertiles, using the second tertile as the reference category.

Results
Kidney length was strongly correlated with body surface area (2.04 mm; 95% confidence interval [95% CI], 1.95 to 2.13 per 0.1 m2 increase) and eGFR (1.62 mm; 95% CI, 1.52 to 1.73 per 10 ml/min per 1.73 m2 increase). During the median follow-up of 6.3 years, 1317 patients experienced a cardiovascular event, including 711 myocardial infarctions, 369 strokes, and 735 vascular cause deaths. A total of 1462 patients died of any cause and 52 patients developed ESRD. Irrespective of eGFR, patients in the third tertile of kidney length (11.7–16.1 cm) were at higher risk of cardiovascular mortality (hazard ratio, 1.33; 95% CI, 1.05 to 1.67) and cardiovascular events (hazard ratio, 1.28; 95% CI, 1.09 to 1.50). Patients in the first tertile of kidney length (7.8–10.8 cm) were not at higher risk of cardiovascular adverse events.

Conclusions
Large kidney length is related to higher risk of cardiovascular events and mortality in high-risk patients, irrespective of eGFR. Kidney length may serve as a clinical marker to further identify patients at high cardiovascular risk.

Published: May 2017

Kurzfassung
Schwankungen in den Lagerbeständen sind auch heute noch eines der Hauptprobleme, mit denen sowohl einzelne Unternehmen als auch ganze Unternehmensnetzwerke konfrontiert sind. Diese Bestandsschwankungen, die auch als Bullwhip- oder Forrester-Effekt bekannt sind, nehmen in einer von Globalisierung gekennzeichneten und hoch technisierten Wirtschaft weiter zu, sodass Unternehmen gezwungen sind, nach neuen Wegen zu suchen, der beschriebenen Problematik zu begegnen. Während in der Vergangenheit meist soft-oder hardwarebasierte Ansätze verfolgt wurden, die zu einer erhöhten Komplexität des Gesamtsystems, aber meist zu keiner abschließenden Lösung des Problems führten, soll an dieser Stelle ein innovativer Ansatz vorgestellt werden, der den Entscheider – den Menschen – in den Mittelpunkt der Bemühungen stellt. Ziel des hier vorgestellten Lösungswegs mittels Planspielen ist es, die verantwortlichen Personen für die Auswirkungen ihres Handelns zu sensibilisieren, damit neben der Leistungsfähigkeit des eigenen Unternehmens auch der Erfolg des gesamten Netzwerks zu einem zentralen Leitmotiv bei sämtlichen Entscheidungen wird und somit die Bestandsschwankungen in Höhe und Häufigkeit gezielt begrenzt werden können.

Kurzfassung
Wissen lässt sich durch direkte Kommunikation von Mensch zu Mensch gut transferieren. Insbesondere für schnell veränderliches oder spezielles Wissen ist dies gegenüber dokumentenbasierten Methoden vorteilhaft, da der Wissenstransfer schnell und bedarfsorientiert erfolgen kann. Doch wie findet der Rat suchende Mitarbeiter geeignete Ansprechpartner? Elektronische Kommunikation eröffnet hier einen neuen Weg, denn Nachrichten in Form von E-Mail oder News haben bereits die Art und Weise verändert, wie Menschen kommunizieren und zusammenarbeiten. Bisher ging es hauptsächlich darum, Informationen zu übertragen oder abzuspeichern, jedoch weniger darum, sie zu erschließen. Der vorliegende Beitrag beschreibt Gestaltungsformen für Verfahren zur Personensuche und stellt ein am Fraunhofer Institut für Produktionstechnik und Automatisierung (IPA) entwickeltes Softwaresystem vor, das Kommunikationsprofile durch Nachrichtenanalyse automatisch erstellt.
