Caractéristiques limnologiques de 56 lacs du Québec méridional en lien avec l’état trophique
Authors: Tremblay Roxane , Pienitz Reinhard 
Published: July 2015

Les lacs de villégiature du Québec méridional sont soumis à des pressions anthropiques croissantes. Conséquemment, on observe une intensification de l’eutrophisation avec les effets indésirables que cela comporte, tels une diminution de la biodiversité et un accroissement des espèces tolérantes comme les cyanobactéries. Le premier objectif de l’étude consiste à documenter les interactions qui s’opèrent entre les variables limnologiques et géologiques à l’étude et le processus d’eutrophisation. Le second objectif vise à déterminer a posteriori l’état trophique des lacs étudiés. Pour ce faire, des analyses de corrélations, de groupement et de covariances ont été menées grâce à l’utilisation d’une série de données comptant 57 variables environnementales. Les analyses de corrélations ont montré, tel que normalement observé, qu’il y a un lien étroit entre la concentration de phosphore total, l’abondance des algues et la diminution de la transparence de l’eau. De plus, l’accroissement de la biomasse primaire dans les lacs eutrophes et hypereutrophes était corrélé avec l’augmentation des concentrations d’aluminium dissous. Par ailleurs, les résultats montrent que la géologie des bassins versants joue un rôle prépondérant sur les propriétés alcalines des lacs et conséquemment, le niveau de production primaire semble s’en trouver accrue. Enfin, l’ensemble des lacs à l’étude représente un gradient trophique complet, soit des conditions trophiques classées ultra-oligotrophes à hypereutrophes, ce qui permettra d’effectuer une étude comparative entre le gradient trophique et la structure des communautés de diatomées lors des travaux futurs.

Published: July 2015

La décharge non contrôlée d’ordures ménagères de Sidi Yahya se trouve à environ 7 km au sud-est de la ville d’Oujda (Maroc nord-oriental). Le tonnage total de déchets qui y sont déversés est de 1,2 à 1,5 million de tonnes pendant la période de l’exploitation (1990-2005). La surface totale qui a été entièrement utilisée est de 41 hectares. Les eaux souterraines, situées à 30 m environ sous le sol, circulent dans des terrains post-miocènes sur un substratum imperméable formé par les marnes du Miocène. Le sol est de type calcimagnésique peu profond, avec une couche plus ou moins importante de limons et d’argiles. Les eaux provenant des déchets eux-mêmes ou issues de la dégradation de la matière organique en conditions aérobies, ainsi que les eaux météoriques, en percolant à travers les déchets, s’enrichissent en divers polluants appelés lixiviats ou percolats. Afin de connaître la destination de ces percolats dans le sous-sol, une étude géophysique par imagerie électrique a été menée dans la partie dégagée de la décharge. Quatre profils de reconnaissance ont été réalisés selon le dispositif dipôle-dipôle. Les résultats de la prospection géoélectrique ont montré que les très faibles résistivités électriques (< 5 Ωm), ont été observées au sein et à l’aval direct du site de la décharge. Ces résultats mettent bien en évidence des zones électriquement très conductrices et elles indiquent la progression du panache de lixiviats dans le sous-sol. La partie centrale de la décharge est l’endroit sous lequel la contamination a atteint des profondeurs qui dépassent les 20 m. Ceci plaide en faveur d’une forte minéralisation des eaux circulant dans les formations sous-jacentes au site, dont la source potentielle est liée à une contamination par des eaux de lixiviats très minéralisées et chargées en matière organique.
Operative Treatment of Ingrown Toenail by Nail Fold Resection Without Matricectomy
Authors: DeBrule Michael B. 
Published: July 2015

Background
Many operative techniques have been studied for correction of ingrown toenails, yet the role of nail fold resection without matricectomy is poorly defined. Current literature on this topic is sparse, and previous systematic reviews are absent.

Methods
A MEDLINE/Cumulative Index to Nursing and Allied Health Literature/Scopus search was performed and a systematic review was undertaken for articles discussing surgical treatment of ingrown toenail by nail fold resection without matricectomy. Outcome measures were systematically reported, and variations in operative technique were identified.

Results
Of the 14 articles that fit the inclusion criteria, 2 were level V evidence, 11 were level IV, and 1 was level III. Minimum follow-up time and the criteria for a satisfactory outcome were not consistently defined. Recurrence rates varied from 0% to 20%. The postsurgical infection rate was 0% for all nine studies reporting infection. Ten different operative techniques were identified. Three studies used partial or total nail avulsion as an adjunctive operative procedure. Triangular-, crescent-, elliptical-, semi-elliptical–, and radical-shaped skin excision strategies were identified. Primary and secondary intentions were used for closure.

Conclusions
Operative algorithms for the treatment of ingrown toenail are still unclear regarding nail fold resection without matricectomy and are supported by almost entirely level IV evidence. Future prospective comparative studies and randomized trials are necessary to support and strengthen current practice.

Authors: Mendel Shaun , Curtis Donald , Page Jeffrey C. 
Published: July 2015

Background
Interprofessional collaboration is key to quality outcomes in the health-care systems of today. Simulation is a common tool in podiatric medical education, and interprofessional education has become more common in podiatric medicine programs. Interprofessional simulation is the blending of these educational strategies.

Methods
A quantitative design was used to determine the impact of an isolated interprofessional podiatric surgical simulation between nurse anesthesia and podiatric medical students.

Results
Statistically significant differences were observed among participants between preintervention and postintervention surveys using the revised Interdisciplinary Education Perception Scale.

Conclusions
Interprofessional simulation can be an effective educational opportunity for podiatric medical and nurse anesthesia students.
Methodological Quality of Randomized Trials Published in the Journal of the American Podiatric Medical Association, 1999–2013
Authors: Landorf Karl B. , Menz Hylton B. , Armstrong David G. , Herbert Robert D. 
Published: July 2015

Background
Randomized trials must be of high methodological quality to yield credible, actionable findings. The main aim of this project was to evaluate whether there has been an improvement in the methodological quality of randomized trials published in the Journal of the American Podiatric Medical Association (JAPMA).

Methods
Randomized trials published in JAPMA during a 15-year period (January 1999 to December 2013) were evaluated. The methodological quality of randomized trials was evaluated using the PEDro scale (scores range from 0 to 10, with 0 being lowest quality). Linear regression was used to assess changes in methodological quality over time.

Results
A total of 1,143 articles were published in JAPMA between January 1999 and December 2013. Of these, 44 articles were reports of randomized trials. Although the number of randomized trials published each year increased, there was only minimal improvement in their methodological quality (mean rate of improvement = 0.01 points per year). The methodological quality of the trials studied was typically moderate, with a mean ± SD PEDro score of 5.1 ± 1.5. Although there were a few high-quality randomized trials published in the journal, most (84.1%) scored between 3 and 6.

Conclusions
Although there has been an increase in the number of randomized trials published in JAPMA, there is substantial opportunity for improvement in the methodological quality of trials published in the journal. Researchers seeking to publish reports of randomized trials should seek to meet current best-practice standards in the conduct and reporting of their trials.
Drought‐induced variability in dissolved organic matter composition in a marsh‐dominated estuary
Authors: Medeiros Patricia M. , Seidel Michael , Dittmar Thorsten , Whitman William B. , Moran Mary Ann 
Published: July 2015

AbstractThe composition of dissolved organic matter (DOM) in an estuary characterized by extensive salt marsh vegetation was investigated at the molecular level using ultrahigh‐resolution mass spectrometry and stable carbon isotope analyses. Samples from multiple seasons covered different hydrological regimes, including anomalously low‐discharge conditions. The untargeted approach used allowed for identifying the DOM molecular signatures associated with different DOM sources in the estuary. DOM composition was strongly modulated by river discharge at monthly scales, with high river flow leading to significant increases in the terrigenous signature of the DOM throughout the estuary. During a severe/exceptional drought, estuarine DOM was imprinted with a distinct signature of marsh‐derived compounds. The frequency of occurrence of anomalously low‐discharge conditions seems to have increased over the last decades. If predictions of anthropogenically driven changes in hydroclimate are confirmed, they will likely be accompanied by changes in DOM composition in estuaries at multidecadal time scales.
Imaging widespread seismicity at midlower crustal depths beneath Long Beach, CA, with a dense seismic array: Evidence for a depth‐dependent earthquake size distribution
Authors: Inbal Asaf , Clayton Robert W. , Ampuero Jean‐Paul 
Published: July 2015

AbstractWe use a dense seismic array composed of 5200 vertical geophones to monitor microseismicity in Long Beach, California. Poor signal‐to‐noise ratio due to anthropogenic activity is mitigated via downward‐continuation of the recorded wavefield. The downward‐continued data are continuously back projected to search for coherent arrivals from sources beneath the array, which reveals numerous, previously undetected events. The spatial distribution of seismicity is uncorrelated with the mapped fault traces, or with activity in the nearby oil‐fields. Many events are located at depths larger than 20 km, well below the commonly accepted seismogenic depth for that area. The seismicity exhibits temporal clustering consistent with Omori's law, and its size distribution obeys the Gutenberg‐Richter relation above 20 km but falls off exponentially at larger depths. The dense array allows detection of earthquakes two magnitude units smaller than the permanent seismic network in the area. Because the event size distribution above 20 km depth obeys a power law whose exponent is near one, this improvement yields a hundred‐fold decrease in the time needed for effective characterization of seismicity in Long Beach.

AbstractWe use observations from the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft, in orbit around Mercury, to investigate interplanetary coronal mass ejections (ICMEs) near 0.3 AU. MESSENGER is the first spacecraft since Helios 1 and 2 in the 1980s to make in situ measurements of the interplanetary medium at heliocentric distances < 0.5 AU. As such, it presents a unique opportunity for observing the innermost heliosphere. It also allows for observations of ICMEs well within 1 AU to study their evolution as they expand and propagate outward, interacting with the solar wind. We catalog ICME events observed by the MESSENGER Magnetometer between 2011 and 2014 and present statistical analyses of ICME properties at Mercury. In addition, using existing data sets of ICMEs at 1 AU, we investigate key ICME property changes from Mercury to 1 AU. We find good agreement with previous studies for the magnetic field strength dependence on distance, and we also find evidence that ICME deceleration continues past the orbit of Mercury. This paper describes the database of ICMEs from MESSENGER orbital observations around Mercury, which is publicly available through the supporting information (Table S1) associated with this manuscript and the Virtual Energetic Particle Observatory. Our ICME database will prove particularly useful for multipoint spacecraft studies of recent ICMEs, as well as for model validation of ICME properties.

Published: July 2015

AbstractReaction between a β‐diketiminato magnesium hydride and carbon monoxide results in the isolation of a dimeric cis‐enediolate species through the reductive coupling of two CO molecules. Under catalytic conditions with PhSiH3, an observable magnesium formyl species may be intercepted for the mild reductive cleavage of the CO triple bond.
Blends of polylactide and poly(3‐hydroxybutyrate‐co‐3‐hydroxyvalerate) with low content of hydroxyvalerate unit: Morphology, structure, and property
Authors: Liu Qingsheng , Wu Cong , Zhang Hongxia , Deng Bingyao 
Published: July 2015

ABSTRACTThe Polylactide (PLA)/poly(3‐hydroxybutyrate‐co‐3‐hydroxyvalerate) (PHBV) blends with four different weight ratios were prepared by melt mixing. PLA and PHBV in PLA/PHBV blends were immiscible while the weak interaction between PLA and PHBV existed. The PHBV domains below 2 μm were dispersed in PLA matrix uniformly. The addition of PHBV made the crystallization of PLA easier due to PHBV acting as nucleating agent. PLA spherulites in PLA/PHBV blends presented various banded structures. In addition, the crystallinity of neat PLA was lower than those of PLA/PHBV blends. With the increase of PHBV content in PLA/PHBV blends, the crystallinity of PLA/PHBV blends increased. PHBV could enhance significantly the toughness of PLA. However, with the increase of PHBV content, the yield stress (σy), tensile modulus (E), and the yield strain (εy) of PLA/PHBV blends decreased gradually. In addition, incorporation of PHBV to PLA caused a transformation from an optical transparent to an opaque system. © 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 42689.

Authors: Du Yicheng , Chen Fangping , Zhang Yachuan , Rempel Curtis , Thompson Michael R. , Liu Qiang 
Published: July 2015

ABSTRACTThermal processing of two potato protein isolates (PPIs) with glycerol as a plasticizer was explored in this study. The PPIs were pretreated by alkali or alkali under reducing conditions. The PPIs before and after pretreatment were analyzed by sodium dodecyl sulfate polyacrylamide gel electrophoresis, differential scanning calorimetry, and Fourier transform infrared spectroscopy. The effects of plasticizer content and pretreatment on mechanical and thermo‐mechanical properties of the compression‐molded biopolymers were studied. The highest tensile strengths obtained were 20–25 MPa and the biopolymer can be brittle or ductile depending on the plasticizer contents. The molecular weight and protein structure of the PPIs markedly affected the resultant biopolymers’ static and dynamic mechanical properties. The pretreatment of PPIs caused distinctly different changes in the mechanical properties of the two PPIs. © 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 42723.
Fabrication of durable hydrophobic cellulose surface from silane‐functionalized silica hydrosol via electrochemically assisted deposition
Authors: Guo Ning , Chen Yuanhui , Rao Qingqing , Yin Yunjie , Wang Chaoxia 
Published: July 2015

ABSTRACTDurable excellent hydrophobic surface on cellulose substrate was fabricated from the silica hydrosol functionalized with silane chemicals by a facile electrochemically assisted deposition technique. The silica hydrosol was synthesized using tetraethoxysilane (TEOS) as the precursor and sodium dodecylbenzene (SDBS) as the emulsifier under acidic conditions. The hydrophobic silane modifiers including octyltriethoxysiliane (OTES), dodecyltriethoxysiliane (DTES) and isooctyltriethoxysiliane (iso‐OTES) and the silane‐coupling agent γ‐mercaptopropyltriethoxysilane (MPTES) were used to dope the silica hydrosol for preparing durable hydrophobic cellulose surface. The cellulose surface modified with silane modifier iso‐OTES exhibited the best hydrophobicity with water contact angle of 162.3 ± 0.5° due to its non‐polar and hydrolytically stable of Si(C8H17) groups. The addition of silane‐coupling agent MPTES containing the SH group led to good durability of hydrophobicity with water contact angle of 130.0 ± 1.2° after 20 washing times. © 2015 Wiley Periodicals, Inc.

Study on the poly(3‐hydroxybutyrate‐co−4‐hydroxybutyrate)‐based composites toughened by synthesized polyester polyurethane elastomer
Authors: Su Tianxiang , Zhang Rui , Wang Jianjian , Shao Wei , Hu Yuan 
Published: July 2015

ABSTRACTIn this study, polycaprolactone(PCL)‐based polyurethane (PU) elastomer containing 45 wt % hard segment component was synthesized and characterized by fourier transform infrared spectroscopy, gel permeation chromatography, and X‐ray diffraction. As a toughening agent, the as‐synthesized PU was incorporated into biodegradable poly(3‐hydroxybutyrate‐co‐4‐hydroxybutyrate) [P(3,4)HB] by solution casting to prepare P(3,4)HB/PU composites. The microstructure and properties of P(3,4)HB/PU composites were investigated using transmission electron microscopy, X‐ray diffraction, tensile testing, scanning electron microscopy, differential scanning calorimetry, thermogravimetric analysis, and activated sludge degradation testing. The results show that PU can disperse well in a P(3,4)HB matrix. The elongation at break of P(3,4)HB/PU composites is remarkably increased while the yield strength and elastic modulus are decreased with an increase in PU content. At the same time, it is found that the fracture characteristic of P(3,4)HB is obviously transformed from brittleness into ductility with a gradual increase in PU loading. Moreover, the thermal stability of P(3,4)HB/PU composites is significantly improved compared with that of pure P(3,4)HB. In addition, the biodegradation rate of P(3,4)HB/PU composites is evidently reduced with the increase of PU content in the activated sludge degradation testing. © 2015 Wiley Periodicals, Inc. J.

Authors: Aoki Hiroshi 
Published: July 2015

AbstractNumerous researchers have devoted a great deal of effort over the last few decades to the development of electrochemical oligonucleotide detection techniques, owing to their advantages of simple design, inherently small dimensions, and low power requirements. Their simplicity and rapidity of detection makes label‐free oligonucleotide sensors of great potential use as first‐aid screening tools in the analytical field of environmental measurements and healthcare management. This review article covers label‐free oligonucleotide sensors, focusing specifically on topical electrochemical techniques, including intrinsic redox reaction of bases, conductive polymers, the use of electrochemical indicators, and highly ordered probe structures.
The Mixed Robust /FTS Control Problem Analysis and State Feedback Control
Authors: Amato Francesco , Cosentino Carlo , Tommasi Gianmaria De 
Published: July 2015

AbstractIn this paper we deal with the mixed
/finite‐time stability control problem. More specifically, given an open loop uncertain linear system, we provide a necessary and sufficient condition for quadratic input‐output finite‐time stability with an
bound. Exploiting this result we also give a sufficient condition to solve the related synthesis problem via state‐feedback. The property of quadratic input‐output finite‐time stability with an
bound implies that the system under consideration satisfies an
performance bound between the disturbance input and the controlled output and, at the same time, is input‐output finite‐time stable for all admissible uncertainties. This condition requires the solution of a feasibility problem constrained by a pair of differential linear matrix inequalities (LMIs) coupled with a time‐varying LMI. The proposed technique is illustrated by means of both a numerical and a physical example.

AbstractThe hydrogen Balmer‐α emission line spectrum of ten diffuse ionization sources in the Milk Way – NGC 40 (WC8), NGC 2022, NGC 6210, NGC 6618 (M17, Sh2‐45), NGC 6720 (M57), NGC 6781, NGC 6888 (Sh2‐105), NGC 6992 (Sh2‐103), NGC 7635 (Sh2‐162,) and IC 1848 (Sh2‐199) – has been investigated using a dual etalon Fabry‐Pérot optical spectrometer (DEFPOS) aatached to the 150 cm RTT150 telescope at TUBITAK National Observatory (TUG, Antalya, Turkey: 36° 51′ N; 30° 20′ E; elevation: 2547 m). All of our galactic Hα observations discussed in this paper were carried out during the nights of 2013 June 21–24 with exposure time of 3600 s. As main results the intensity, the full width at half maximum, and the radial velocity with respect to the LSR have been determined for each data set. The intensities, the radial velocities, and the line widths of the Hα emission line vary from 59.15 to 8923.44 R, –46.72 to +54.07 km s–1, and 31.4 to 48.01 km s–1, respectively. The radial velocities and the half‐widths of the Hii regions and planetary nebulae determined from our measurements are found tobe consistent with values given in literature, especially with those in Schneider et al. (1983) and Fich et al. (1990). (© 2015 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

AbstractCystic fibrosis (CF) is a lethal genetic disease caused by the loss or dysfunction of the CF transmembrane conductance regulator (CFTR) channel. F508del is the most prevalent mutation of the CFTR gene and encodes a protein defective in folding and processing. VX‐809 has been reported to facilitate the folding and trafficking of F508del‐CFTR and augment its channel function. The mechanism of action of VX‐809 has been poorly understood. In this study, we sought to answer a fundamental question underlying the mechanism of VX‐809: does it bind CFTR directly in order to exert its action? We synthesized two VX‐809 derivatives, ALK‐809 and SUL‐809, that possess an alkyne group and retain the rescue capacity of VX‐809. By using CuI‐catalyzed click chemistry, we provide evidence that the VX‐809 derivatives bind CFTR directly in vitro and in cells. Our findings will contribute to the elucidation of the mechanism of action of CFTR correctors and the design of more potent therapeutics to combat CF.
