Published: August 2014

Poly(ethylene 2,5‐furandicarboxylate) (PEF) is an emergent biobased polyester whose chemical structure is analogous to poly(ethylene terephthalate). Pilot‐scale PEF is synthesized through the direct esterification process from 2,5‐furandicarboxylic acid and bio‐ethylene glycol. Wide‐angle X‐ray diffraction (WAXD) measurements reveal similar crystallinities and unit cell structures for melt‐crystallized and glass‐crystallized samples. The non‐isothermal crystallization of PEF sample is investigated by means of DSC experiments both from the glass and the melt. The temperature dependence of the effective activation energy of the growth rate is obtained from these data, and the results show that the glass and early stage of the melt crystallization share common dynamics. Hoffman–Lauritzen parameters and the temperature at maximum crystallization rate are evaluated. It is found that the melt‐crystallization kinetics undergo a transition from regime I to II; however, the crystal growth rate from the melt shows an atypical depression at T < 171 °C compared with the predicted Hoffman–Lauritzen theory.

Published: August 2014

AbstractFusobacterium nucleatum is a common oral organism that can provide adhesive and metabolic support to developing periodontal bacterial communities. It is within the context of these communities that disease occurs. We have previously reported whole cell proteomics analyses of Porphyromonas gingivalis and Streptococcus gordonii in early‐stage communities with each other and with F. nucleatum, modeled using 18 h pellets. Here, we report the adaptation of F. nucleatum to the same experimental conditions as measured by differential protein expression. About 1210 F. nucleatum proteins were detected in single species F. nucleatum control samples, 1192 in communities with P. gingivalis, 1224 with S. gordonii, and 1135 with all three species. Quantitative comparisons among the proteomes revealed important changes in all mixed samples with distinct responses to P. gingivalis or S. gordonii alone and in combination. The results were inspected manually and an ontology analysis conducted using DAVID (Database for annotation, visualization, and integrated discovery). Extensive changes were detected in energy metabolism. All multispecies comparisons showed reductions in amino acid fermentation and a shift toward butanoate as a metabolic byproduct, although the two organism model community with S. gordonii showed increases in alanine, threonine, methionine, and cysteine pathways, and in the three species samples there were increases in lysine and methionine. The communities with P. gingivalis or all three organisms showed reduced glycolysis proteins, but F. nucleatum paired with S. gordonii displayed increased glycolysis/gluconeogenesis proteins. The S. gordonii containing two organism model also showed increases in the ethanolamine pathway while the three species sample showed decreases relative to the F. nucleatum single organism control. All of the nascent model communities displayed reduced translation, lipopolysaccharide, and cell wall biosynthesis, DNA replication and DNA repair.

Fibre‐reinforced plastic (FRP) – an innovative approach to further development of rock bolt technology and the development of new outlets in tunnel and structural engineering
Authors: Borgmeier Erich 
Published: August 2014

AbstractFibre‐reinforced plastics, known as CFRP or GRP, are used as securing elements in the form of rock bolts or concrete reinforcement in mining and tunnel engineering, civil engineering and geotechnics. Applications according to exposure classes following Eurocode 2 in the ground, in rock and concrete, which are exposed to enhanced chemical attack by groundwater and pollutant loading, mine water flow, alkalinity of the concrete, frost and thaw conditions and de‐icing salt exposure, seawater and other moist‐warm changeover conditions, also place the highest demands on permanent chemical resistance, quite apart from the high mechanical demands on the composite material.The applications discussed here require the lowest possible elastic expansion and long‐term resistance, apart from high service loads as well as good composite behavior, slight creeping, self‐extinguishing and a series of other properties. A somewhat more precise consideration of these requirements, the state of the art and other development trends show that several products are now available that for the most part meet all of these requirements.In the medium term material and product development will facilitate quite new application possibilities like pre‐ and post‐stressing technology or combinations of primary and secondary support construction, which in technical and commercial respects will open up new perspectives in mining, but in particular also in tunnel engineering and as before in civil engineering.
Network pricing: can both ISP and P2P benefit?
Authors: Li Zhen , Liao Qi 
Published: August 2014

SummaryInternet service providers are facing increasing back pressure from rising access demand by users, especially peer‐to‐peer (P2P)‐based applications that greatly enhance the large‐scale distribution of content into and out of their networks. With the ever increasing consumption pressure on scarce bandwidth resources, ISPs have been forced to reconsider their business model of overselling ‘all‐you‐can‐eat’ broadband at flat rates. Technical solutions such as traffic differentiation or blocking violate the principle of network neutrality; traffic shaping and deep packet analysis fall short in the presence of encryption; and P4P (localized P2P)‐based solutions are difficult to achieve in a heterogeneous environment. Economically, various usage‐based pricing schemes have been proposed and discussed. While they can improve efficiency in bandwidth consumption, they tend to face strong customer resistance as users have strong preference in favour of simple flat rates. We argue that any feasible pricing reforms cannot deviate much from the current flat rates while providing financial incentives for bandwidth hogs to limit their bandwidth access. In contrast to normal usage‐based pricing models that charge by volume, we propose a temporal‐based pricing model that may generate a mutually beneficial solution that can not only increase the profitability of ISPs but also accommodate P2P, rather than killing it, without changing the software, protocols or hardware that clients or ISPs use on the network.Copyright © 2014 John Wiley & Sons, Ltd
Probing microphase separation and proton transport cooperativity in polymer‐tethered 1H‐tetrazoles
Authors: Chaloux Brian L. , Ricks‐Laskoski Holly L. , Miller Joel B. , Saunders Kaitlin M. , Hickner Michael A. 
Published: August 2014

ABSTRACTTo elucidate the driving forces for phase separation and proton conductivity in polystyrenic alkoxy 1H‐tetrazole (PS‐Tet), an analogous polystyrenic alkoxy carboxylic acid (PS‐HA) was synthesized and the conductivity and chain dynamics of both materials measured. Proton and polymer motions illustrate dramatic differences in the nonaqueous behavior of carboxylic acids and 1H‐tetrazoles, belying similarities in their aqueous properties. Exceptional interactions between 1H‐tetrazoles drive phase separation not observed in PS‐HA or reported for other azole‐containing homopolymers. PS‐HA and PS‐Tet exhibit both dry (0% relative humidity) and hydrated proton dissociations proportional to their aqueous pKas, with residual water acting as the proton acceptor in both polymers. While water is the sole contributor to mobility in PS‐HA, PS‐Tet exhibits dynamic interactions with water allowing 1H‐tetrazole moieties to contribute to proton conduction even in the hydrated state. © 2014 Wiley Periodicals, Inc.

SummaryBackgroundPalivizumab prophylaxis for RSV has been consistently reported to reduce the risk of hospital admissions related to RSV infection in children with symptomatic cardiac disease. This study was designed to investigate the efficacy of palivizumab prophylaxis among infants with congenital heart disease (CHD) in Turkey.MethodsA total of 91 infants with CHD who received palivizumab prophylaxis and 96 infants with CHD without prophylaxis (0–12 months:52; 12–24 months:44) were included in this single‐center retrospective case control study. Data on patient characteristics, household environment, and LRTIs were evaluated.ResultsIn patients without prophylaxis, the rate of overall lower respiratory tract infections (LRTIs) (P < 0.001), complicated LRTIs (P = 0.006), LRTI‐related hospitalization (P < 0.001) and ICU admission (P = 0.008) were significantly higher than control patients. Weight <10th percentile (odds ratio (OR) 5.78, 95% confidence interval (CI):1.37; 24.4, P < 0.001) and concomitant chromosome abnormality (OR 4.01, 95% CI:1.01;16.45, P < 0.001) in patients with prophylaxis, while presence of a sibling <11 years of age (OR 3.38, 95% CI: 1.21; 9.46, P < 0.001) and congestive heart failure (OR 8.63, 95% CI: 2.81; 26.6, P < 0.001) in the control group were the significant correlates of LRTI‐related hospitalization.ConclusionOur findings revealed significantly lower rate of overall and complicated LRTIs, LRTI‐related hospitalization and ICU admissions in infants with CHD via palivizumab prophylaxis.

Secure publish/subscribe‐based certificate status validations in mobile ad hoc networks
Authors: Masdari Mohammad , Jabbehdari Sam , Bagherzadeh Jamshid 
Published: August 2014

AbstractFreshness of certificate status information is very important in validating public key certificates. However, existing certificate validation schemes suffer from high inconsistency, which makes network vulnerable to various security attacks. In this paper, we propose a new publish/subscribe‐based certificate validation scheme that provides fresh certificate status information in the mobile ad hoc networks. This scheme increases the security of public key infrastructure‐based security systems and improves the scalability of certificate validation systems. Also, according to the simulation results, our solution effectively decreases the processing overheads on responder nodes and reduces the messaging overhead of certificate status validations in mobile ad hoc networks.

Langevin power curve analysis for numerical wind energy converter models with new insights on high frequency power performance
Authors: Mücke Tanja A. , Wächter Matthias , Milan Patrick , Peinke Joachim 
Published: August 2014

AbstractBased on the Langevin equation, it has been proposed to obtain power curves for wind turbines from high‐frequency data of wind speed measurements u(t) and power output P(t). The two parts of the Langevin approach, power curve and drift field, give a comprehensive description of the conversion dynamic over the whole operating range of the wind turbine. The method deals with high‐ frequent data instead of 10 min means. It is therefore possible to gain a reliable power curve already from a small amount of data per wind speed. Furthermore, the method is able to visualize multiple fixed points, which is, e.g. characteristic for the transition from partial to full load or in case the conversion process deviates from the standard procedures. In order to gain a deeper knowledge, it is essential that the method works not only for measured data but also for numerical wind turbine models and synthetic wind fields. Here, we characterize the dynamics of a detailed numerical wind turbine model and calculate the Langevin power curve for different data samplings. We show how to obtain reliable results from synthetic data and verify the applicability of the method for field measurements with ultra‐sonic, cup, and Lidar measurements. The independence of the fixed points on site‐ specific turbulence effects is also confirmed with the numerical model. Furthermore, we demonstrate the potential of the Langevin approach to detect failures in the conversion process and thus show the potential of the Langevin approach for a condition monitoring system.

Characterizing the importance of habitat patches in maintaining landscape connectivity for Tibetan antelope in the Altun Mountain National Nature Reserve, China

Published: August 2014

AbstractConnectivity of habitat patches is crucial for wildlife dispersal and survival, and identifying patches with high importance for maintaining connectivity can aid effective wildlife management. Knowledge of the habitat distribution of the Tibetan antelope in the Altun Mountain National Nature Reserve, which is essential for connectivity analysis, remains limited. We analyzed potential habitat distribution and priority patches using GIS‐based habitat suitability modeling with three weighting factors and evaluated the connectivity of habitat patches under four dispersal distance scenarios. Patches with high habitat suitability covered 25.39 % of the total area, and these patches were selected for connectivity analysis as resource patches. Connectivity analysis indicated that, although the overall probability of connectivity (PC) showed an upward trend with increasing dispersal distance, the importance of each patch varied considerably under different dispersal distance scenarios. Transfer analysis of patch numbers between different importance levels revealed that the number of patches becoming less important was higher than the number of patches becoming more important when dispersal distance increased. In addition, nine patches covering 38.49 % of the suitable habitat area were identified as priority patches, in particular the patches near the Kardun and the Karchuka inspection stations. We also found that the habitat distribution of the Tibetan antelope obtained from the suitability model matched the population distribution determined by a field survey. Correlation analysis between patch area and the percentage of PC index value loss (dPC) revealed that the larger patches in this region were more likely to be important for maintaining connectivity.

Published: August 2014

AbstractThe purpose of this study is to determine the trans fat level in French fries sold in different fast food outlets in Karachi. In the present study, attenuated total reflectance‐Fourier transform infrared (ATR‐FTIR) spectroscopy was used for the quantification of trans fatty acid (TFA). A number of studies have been reported on trans fat in different regions of the world, but no categorical study has yet discussed the trans fat in fast food products in Karachi. Amongst the samples examined, the total trans fatty acid content was in the range of 0.11 ± 0.01–24.00 ± 0.25 %. Most of the samples contain a high percentage of TFA. There is an urgent need to monitor and regulate the level of trans fat in order to reduce the health risk to the consumers of fast food items in Karachi, Pakistan.

Les tumeurs testiculaires à cellules de Leydig sont rares, elles représentent entre 1 et 3 % de l’ensemble des tumeurs testiculaires. L’atteinte bilatérale synchrone est exceptionnelle. Découverte dans 20 % des cas lors de la première décennie, elle peut être retrouvée dans toutes les tranches d’âge, le diagnostic étant effectué après 50 ans dans 25 % des cas. Le diagnostic est classiquement suspecté devant une anomalie sécrétoire intéressant les hormones sexuelles et seule l’histologie confirme le diagnostic. Nous rapportons le cas d’un patient âgé de 25 ans qui présente une tumeur bilatérale synchrone à cellules de Leydig traité par orchidectomie unilatérale et tumorectomie controlatérale.

AbstractMotivation: Numerous public microarray datasets are valuable resources for the scientific communities. Several online tools have made great steps to use these data by querying related datasets with users’ own gene signatures or expression profiles. However, dataset annotation and result exhibition still need to be improved.Results: ExpTreeDB is a database that allows for queries on human and mouse microarray experiments from Gene Expression Omnibus with gene signatures or profiles. Compared with similar applications, ExpTreeDB pays more attention to dataset annotations and result visualization. We introduced a multiple-level annotation system to depict and organize original experiments. For example, a tamoxifen-treated cell line experiment is hierarchically annotated as ‘agent→drug→estrogen receptor antagonist→tamoxifen’. Consequently, retrieved results are exhibited by an interactive tree-structured graphics, which provide an overview for related experiments and might enlighten users on key items of interest.Availability and implementation: The database is freely available at http://biotech.bmi.ac.cn/ExpTreeDB. Web site is implemented in Perl, PHP, R, MySQL and Apache.Contact: boxc@bmi.ac.cnSupplementary information: Supplementary data are available at Bioinformatics online.

Published: August 2014

ObjectiveTo assess whether variations in maternal haemoglobin levels during pregnancy are associated with cardio‐metabolic risk factors in school age children.DesignPopulation‐based prospective cohort study.SettingRotterdam, The Netherlands, 2002–2012.PopulationMothers and children (n = 5002) participating in the Generation R Study.MethodsWe obtained maternal haemoglobin levels during early pregnancy (median gestational age 14.6 weeks [95% range 10.3, 25.3]) from venous blood samples. Maternal anaemia and elevated haemoglobin levels were based on World Health Organization criteria. We measured childhood cardio‐metabolic risk factors at age 6 years.Main outcome measuresCardio‐metabolic risk factors included body mass index, total fat mass percentage, android/gynoid fat mass ratio, systolic and diastolic blood pressure, left ventricular mass, and blood levels of cholesterol, insulin and C‐peptide.ResultsMaternal haemoglobin levels were not associated with childhood body mass index, total fat mass percentage, android/gynoid fat mass ratio, systolic blood pressure, cholesterol or insulin levels. Compared with children with normal maternal haemoglobin levels, children from anaemic mothers had slightly higher diastolic blood pressures (difference 0.70 mmHg, 95% CI 0.12, 1.29) and lower C‐peptide levels (difference factor 0.93, 95% CI 0.88, 0.98), and children of mothers with elevated haemoglobin levels had lower left ventricular masses (difference −1.08 g, 95% CI −1.88, −0.29). These associations attenuated after adjustment for multiple testing and were not consistent within linear models.ConclusionThese results do not strongly support the hypothesis that variations in maternal haemoglobin levels during pregnancy influence cardio‐metabolic risk factors in childhood.
