Abstract
Objective—To describe the epizootiological investigation of an outbreak of Q fever (Coxiella burnetii infection).
Design—Epidemiological study.
Animals—17 goat herds in Washington, Montana, and Oregon.
Procedures—In April 2011, an abortion storm at a commercial goat farm in Washington was determined to be caused by C burnetii. A joint epidemiological investigation by public health and veterinary professionals was subsequently performed to assess the extent of the outbreak by performing a trace-forward of goats sold from the index farm, to determine risk factors associated with infection, and to implement control measures. A herd management plan was developed to control the outbreak and reduce risk of human exposure. Quarantine and temporary holds preventing the sale or movement of goats allowed time for trace-forward investigation, education of farmers regarding disease risk, and testing to determine the scope of the outbreak.
Results—17 farms were affected; 21 human Q fever cases were identified. Bacterial shedding in feces, vaginal fluid, or milk was confirmed in 156 of 629 (25%) goats tested by PCR assay. Seroprevalence of antibodies against C burnetii in goats, determined by ELISA, was 12%. The risk for C burnetii infection in goats was highest among females, those on farms associated with human Q fever, and those on Washington farms. A protective effect was observed for goats at farms where the primary form of goat carcass disposal was burial.
Conclusions and Clinical Relevance—This outbreak illustrated the importance of a joint investigation for zoonotic pathogens and the need to expand and strengthen relationships between medical, public health, and veterinary partners. Heightened awareness and enhanced veterinary diagnostic capabilities for C burnetii are needed to identify and control outbreaks expediently.
Potential for iatrogenic coil embolization of the caudal cerebellar artery during treatment of internal carotid artery bifurcation in two horses with guttural pouch mycosis
Authors: Bonilla Alvaro G. , Scansen Brian A. , Hurcombe Samuel D. , Mudge Margaret C. 
Published: December 2015

Abstract
Case Description—2 horses were examined for chronic nasal discharge secondary to unilateral guttural pouch mycosis.
Clinical Findings—Initial endoscopic examination of both horses confirmed the presence of a fungal plaque on the dorsomedial aspect of the medial compartment of the guttural pouch (auditory tube diverticulum) involving the internal carotid artery (ICA). No signs of hemorrhage or neurologic deficits were present at admission.
Treatment and Outcome—Transarterial stainless steel coil embolization of the affected ICA was performed under general anesthesia, with fluoroscopic guidance. During treatment, an aberrant branch of the ICA, or a proposed bifid ICA, that anastomosed with the caudal cerebellar artery was identified. Occlusion of the distal (noncardiac) side of the aberrant branch was performed in both horses because of potential mycotic involvement at that level. Following treatment, resolution of the mycotic infection was observed in both horses; however, 1 horse developed neurologic signs compatible with unilateral caudal cerebellar artery ischemia on recovery from anesthesia; these signs resolved over the following 2 months.
Clinical Relevance—Findings highlighted variability of the anatomy of the ICA in 2 horses that was identified during treatment for guttural pouch mycosis and identified caudal cerebellar artery infarction as a potential complication of treatment. Because of the size and pathway of both arterial branches, we suggest that the term bifurcation of the ICA is more appropriate than aberrant branching, as has been previously described in the literature. The information in this report may be of value to clinicians performing procedures involving the vasculature of the head and neck in horses.
Aberrant systemic arterial supply to normal lung arising from the proper hepatic artery discovered during transarterial chemoembolization
Authors: Walsworth Matthew K , Yap Felix Y , McWilliams Justin P 
Published: December 2015

We report a rare case of dual arterial supply to an otherwise normal lung discovered incidentally during initial angiography performed with the intent of chemoembolization of hepatocellular carcinoma. In addition to normal hepatic arterial supply, the proper hepatic artery provided systemic arterial supply to the lower lobe of the left lung. Subsequent chest computed tomography angiography demonstrated a normal tracheobronchial tree and normal pulmonary arterial supply to the lung. Although other anatomic variants have been reported, there are no other reported cases of systemic arterial supply from the proper hepatic artery to the lung. Identifying systemic arterial supply to the lung during angiography is important while performing transcatheter chemoembolization or radioembolization in the liver in order to minimize non-target embolization of the lung.
Vers l'institutionnalisation de l'enseignement autonomisant – La technologie, soutien et obstacle à l'innovation

Un projet de plateforme numérique pour l'apprentissage des langues destiné aux étudiants et aux enseignants du secteur Lansad (langues pour spécialistes d'autres disciplines) est en cours de développement à l'université de Lorraine (UL) (Chateau & Bailly, 2013). Ce projet a pour objectif l'essaimage de plusieurs dispositifs utilisant le potentiel d'outils numériques pour favoriser l'autonomisation d'apprenants (Bailly et al., 2008 ; Chateau & Zumbihl, 2012 ; Carette, Guély & Pereiro, 2011).Les retours positifs d'enseignants et d'apprenants ayant bénéficié de ces apports technologiques ont naturellement impulsé une volonté de sortir de la phase expérimentale pour passer à une institutionnalisation progressive, à travers un projet de plateforme numérique, institutionnalisation qui se révèle problématique. À travers les réponses à deux questionnaires adressés aux enseignants de langues de toute l'université nous identifierons les freins et les réticences constatés au cours du travail de développement de la plateforme. Il est souvent dit que l'innovation technique n'engendre pas nécessairement d'innovation pédagogique. Nous tenterons de mieux comprendre la nature des rapports entre ces deux types d'innovation.
Quantification of precipitation and temperature uncertainties simulated by CMIP3 and CMIP5 models

Published: December 2015

AbstractAssessment of climate change impacts on water resources is extremely challenging, due to the inherent uncertainties in climate projections using global climate models (GCMs). Three main sources of uncertainties can be identified in GCMs, i.e., model structure, emission scenario, and natural variability. The recently released fifth phase of the Coupled Model Intercomparison Project (CMIP5) includes a number of advances relative to its predecessor (CMIP3), in terms of the spatial resolution of models, list of variables, and concept of specifying future radiative forcing, among others. The question, however, is do these modifications indeed reduce the uncertainty in the projected climate at global and/or regional scales? We address this question by quantifying and comparing uncertainty in precipitation and temperature from 6 CMIP3 and 13 CMIP5 models. Uncertainty is quantified using the square root of error variance, which specifies uncertainty as a function of time and space, and decomposes the total uncertainty into its three constituents. The results indicate a visible reduction in the uncertainty of CMIP5 precipitation relative to CMIP3 but no significant change for temperature. For precipitation, the GCM uncertainty is found to be larger in regions of the world that receive heavy rainfall, as well as mountainous and coastal areas. For temperature, however, uncertainty is larger in extratropical cold regions and lower elevation areas.
An ensemble constrained variational analysis of atmospheric forcing data and its application to evaluate clouds in CAM5
Authors: Tang Shuaiqi , Zhang Minghua , Xie Shaocheng 
Published: December 2015

AbstractLarge‐scale atmospheric forcing data can greatly impact the simulations of atmospheric process models (e.g., large eddy simulations, cloud‐resolving models, and single column models (SCMs)) that are used to develop physical parameterizations in global climate models. This study introduces an ensemble variationally constrained objective analysis of atmospheric large‐scale forcing data and its application to evaluate the cloud biases in the Community Atmospheric Model (CAM5). Sensitivities of the variational objective analysis to background data, error covariance matrix, and constraint variables are presented to quantify the uncertainties in the large‐scale forcing data and state variables. Application of the ensemble forcing in the CAM5 SCM during March 2000 intensive operational period at the Southern Great Plains (SGP) of the Atmospheric Radiation Measurement Program shows that the systematic biases in the model simulations (i.e., excessive high clouds and insufficient low clouds) cannot be explained by the uncertainty of large‐scale forcing data, which points to the deficiencies of physical parameterizations. These biases are found to also exist in the global simulation of CAM5 when it is compared with satellite data over the surrounding SGP site for annual and seasonal means.
Low‐temperature plasma processing for the enhancement of surface properties and dyeability of wool fabric
Authors: Mendhe Pankaj , Arolkar Gauree , Shukla Sanjeev , Deshmukh Rajendra 
Published: December 2015

ABSTRACTIn the present investigation, wool fabric was treated with a low‐temperature air plasma. The plasma discharge power and treatment time were varied. The effect of plasma treatment on various fabric properties such as wettability, wickability, dyeability, crease recovery angle, breaking strength, and elongation at break was investigated. Surface morphology was studied using SEM micrographs. The fabric became substantially hydrophilic even with a short duration of air plasma treatment of 30 s with improvement in dye uptake and in the rate of dyeing when dyed at a lower temperature. Under these treatment conditions, aging was almost nil in a dry environment, even after 45 days, whereas some aging was observed in a humid (75% relative humidity) environment. A 20% increase in the breaking strength and 24% increase in the elongation at break were observed with reduction in wrinkle recovery angle to 133–144° from 169° for untreated fabric. © 2015 Wiley Periodicals, Inc.

Preparation of hybrid composite microspheres containing nanosilicon via microsuspension polymerization
Authors: Liu Fandong , Wang Zhoulu , Zhou Yingjie , Liu Xiang 
Published: December 2015

ABSTRACTHybrid composite microspheres with nano‐Si as the core and poly(styrene‐co‐acrylonitrile) as a shell are successfully prepared by a two‐step polymerization technique, which includes dispersion polymerization of styrene and 3‐methacryloxypropyl trimethoxysilane in ethanol for surface modification of nano‐Si followed by microsuspension polymerization of styrene and acrylonitrile in an aqueous phase for encapsulating nano‐Si into an SAN copolymer matrix. The structure and surface properties of modified nano‐Si are investigated by Fourier transform infrared spectroscopy (FTIR) and contact angle. The hybrid composite microspheres are systematically characterized by energy dispersive spectroscopy, thermogravimetric analysis, and transmission electron microscopy (TEM). According to the FTIR spectra and the contact angle experiments, it was determined that a hydrophobic polymer layer was formed on the surface of nano‐Si. TEM showed that nano‐Si was homogeneously dispersed in SAN particles when the loading capacity of nano‐Si in the hybrid composite microspheres was less than 20 wt %. Moreover, scanning electron microscopy and X‐ray photoelectron spectroscopy revealed that there were large amounts of nano‐Si absorbed on the surface of the hybrid composite microspheres, and the mean particle size became much larger when the loading amounts of nano‐Si reached 25 wt %. From this, it can be inferred that nano‐Si overflows from the inner core to the outside surface in the emulsification process and acts as an inorganic dispersant. © 2015 Wiley Periodicals, Inc. J.

Published: December 2015

ABSTRACTOn the basis of the present study, the details of the recovery of cutting oil from oil‐in‐water emulsion using the modified forms of biopolymer chitosan viz., chitosan beads (CB), carboxylated chitosan beads (CCB), and lanthanum incorporated carboxylated chitosan beads (La‐CCB). Various oil sorption experiments were conducted using an extractive gravimetric method by optimizing various parameters such as contact time, pH, sorbent dosage, and initial oil concentration for maximum sorption. It was found that the oil removal percentage was comparatively less in the case of CB and CCB when compared with La‐CCB, which showed 85% of oil removal at acidic condition. The obtained adsorption equilibrium data was explained with Freundlich, Langmuir, D–R, and Tempkin isotherms to find the best fit for the sorption process. Thermodynamic parameters such as ΔG0, ΔH0, and ΔS0 were calculated in order to understand the nature of sorption process. The surface morphology and sorption of oil on the beads were confirmed by FTIR, SEM with EDAX, XRD, TGA, and DSC analysis. This work provides a potential platform for the expansion of oil removal technology. © 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43218.

Published: December 2015

ABSTRACTIn this article, a series of polyurethane (PU)/organic vermiculite (OVMT) composites are prepared by intercalating polymerization. 1,4‐cyclohexane diisocyanate (CHDI) as hard segment of PU is designed to improve the decomposition temperature of composites. Vermiculite (VMT) is modified by method of cation exchange with octadecyl trimethyl ammonium bromide (OTAB); the resulting product OVMT with the function of physical cross‐linking disperses well in soft segment of PU polycarbonate polyol (PCDL), which improves the mechanical properties of composites obviously. This modification further enlarged the interlayer of OVMT and improved the properties of composites. The structure and properties of OVMT and PU/OVMT composites are characterized by Fourier transform infrared spectroscopy, X‐ray diffraction, thermogravimetric analysis, scanning electron microscope, and tensile strength test. The results showed that the layer spacing of OVMT increased 1.41 nm compared with that of VMT (the value of layer spacing of VMT is 0.96 nm) and further enlarged to 2.92 nm by the loading of PCDL. The tensile strength and the strain at break of PUCPB/OVMT (3.0%) composites reached 26.8 MPa and 443%, respectively. The temperature resistance of PUCPB/OVMT (3.0%) composites is above 300°C, which is more suitable for the steam channeling plugging of heavy oil. © 2015 Wiley Periodicals, Inc. J. Appl. Polym.

Structural biology of tumor necrosis factor demonstrated for undergraduates instruction by computer simulation
Authors: Roy Urmi 
Published: December 2015

AbstractThis work presents a three‐dimensional (3D) modeling exercise for undergraduate students in chemistry and health sciences disciplines, focusing on a protein‐group linked to immune system regulation. Specifically, the exercise involves molecular modeling and structural analysis of tumor necrosis factor (TNF) proteins, both wild type and mutant. The structure of the tumor necrosis factor type 1 receptor (TNF‐R1) is also briefly explored. TNF and TNF‐R1 play major roles in maintaining human immune‐system homeostasis. Upon binding with TNFR‐1, the TNF can activate the nuclear factor kappa B (NF‐κB), eventually resulting in apoptosis or cell death. These essential features of the clinically relevant TNF family is explored within the frame work of a readily adaptable tutorial. © 2015 by The International Union of Biochemistry and Molecular Biology, 44:246–255, 2016.

Numerical stability for modelling of dynamic two‐phase interaction
Authors: Mieremet M.M.J. , Stolle D.F. , Ceccato F. , Vuik C. 
Published: December 2015

SummaryDynamic two‐phase interaction of soil can be modelled by a displacement‐based, two‐phase formulation. The finite element method together with a semi‐implicit Euler–Cromer time‐stepping scheme renders a discrete equation that can be solved by recursion. By experience, it is found that the CFL stability condition for undrained wave propagation is not sufficient for the considered two‐phase formulation to be numerically stable at low values of permeability. Because the stability analysis of the two‐phase formulation is onerous, an analysis is performed on a simplified two‐phase formulation that is derived by assuming an incompressible pore fluid. The deformation of saturated porous media is now captured in a single, second‐order partial differential equation, where the energy dissipation associated with the flow of the fluid relative to the soil skeleton is represented by a damping term. The paper focuses on the different options to discretize the damping term and its effect on the stability criterion. Based on the eigenvalue analyses of a single element, it is observed that in addition to the CFL stability condition, the influence of the permeability must be included. This paper introduces a permeability‐dependent stability criterion. The findings are illustrated and validated with an example for the dynamic response of a sand deposit.

ObjectiveAt the cellular level, how excess adiposity promotes atherogenesis is not fully understood. One pathway involves secretion of adipokines that stimulate endothelial dysfunction through increased expression of adhesion molecules. However, the relationship of adiposity to adhesion molecules that promote atherosclerosis is largely unknown.MethodsLinear regression models were used to assess the sex‐specific associations of soluble cellular adhesion molecules (sP‐ and sL‐selectin, sICAM‐1, sVCAM‐1, and sHGF) and adiposity in 5,974 adults examined as part of the Multi‐Ethnic Study of Atherosclerosis (MESA). Adiposity measures included body mass index (BMI), waist‐to‐hip‐ratio (WHR), and computed tomography measures of subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT).ResultsThe mean age was 64 years and 52% were female. In multivariable models adjusting for traditional cardiovascular risk factors, sHGF was positively associated with BMI, WHR, and VAT in both males and females, and sP‐selectin with WHR and VAT in males. sVCAM‐1 was inversely associated with VAT in females only.ConclusionsOur results showed the relation of adiposity to soluble cellular adhesion proteins was similar across adiposity measures and for both sexes. However, the relationship between adiposity and sVCAM‐1 and P‐selectin may be modified by sex and the measure used to assess adiposity.
