Use of greater omentum in the surgical treatment of a synovial cyst in a cat
Authors: Van Goethem B. , Beerden C. , Grussendorf C. , de Rooster H. , Stegen L. 
Published: March 2015

SummaryA 13-year-old cat was diagnosed with a synovial cyst originating from the glenohumeral joint. The cat presented with severe front limb lameness and a non-painful fluctuating swelling on the medial aspect of the humerus. Radiographic examination showed severe bilateral shoulder osteoarthritis with osteophyte formation. The mass was surgically resected and histopathology confirmed the diagnosis of a synovial cyst. Three weeks postoperatively the cyst recurred. Surgical resection was repeated followed by omentalisation of the defect. Throughout the following 3 months the cyst did not recur. Unfortunately, for reasons unrelated to the presented disease, the cat was euthanized shortly afterwards, therefore making a long-term follow-up impossible.

Micro-macro model for prediction of local temperature distribution in heterogeneous and two-phase media
Authors: Furmański Piotr , Seredyński Mirosław , Łapka Piotr , Banaszek Jerzy 
Published: March 2015

Abstract
Heat flow in heterogeneous media with complex microstructure follows tortuous path and therefore determination of temperature distribution in them is a challenging task. Two-scales, micro-macro model of heat conduction with phase change in such media was considered in the paper. A relation between temperature distribution on the microscopic level, i.e., on the level of details of microstructure, and the temperature distribution on the macroscopic level, i.e., on the level where the properties were homogenized and treated as effective, was derived. The expansion applied to this relation allowed to obtain its more simplified, approximate form corresponding to separation of micro- and macro-scales. Then the validity of this model was checked by performing calculations for 2D microstructure of a composite made of two constituents. The range of application of the proposed micro-macro model was considered in transient states of heat conduction both for the case when the phase change in the material is present and when it is absent. Variation of the effective thermal conductivity with time was considered and a criterion was found for which application of the considered model is justified.

Published: March 2015

Abstract
Transient heat transfer is studied and compared in two planeparallel composite walls and one EPIDIAN 53 epoxy resin wall acting as a matrix for both composites. The first of the two walls is made of carbonepoxy composite; the other wall is made of glass-epoxy composite, both with comparable thickness of about 1 mm and the same number of carbon and glass fabric layers (four layers). The study was conducted for temperatures in the range of 20-120 °C. The results of the study of thermal diffusivity which characterizes the material as a heat conductor under transient conditions have a preliminary character. Three series of tests were conducted for each wall. Each series took about 24 h. The results from the three series were approximated using linear functions and were found between (0.7-1.35)×10−7m2/s. In the whole range of temperature variation, the thermal diffusivity values for carbon-epoxy composite are from 1.2 to 1.5 times higher than those for the other two materials with nearly the same thermal diffusivity characteristics.

Authors: Justus Benjamin 
Published: March 2015

AbstractWe present two computational approaches for the purpose of point compression and decompression on Edwards curves over the finite field Fp where p is an odd prime. The proposed algorithms allow compression and decompression for the x or y affine coordinates. We also present a x-coordinate recovery algorithm that can be used at any stage of a differential addition chain during the scalar multiplication of a point on the Edwards curve.

AbstractThis paper considers three general trichotomy concepts for noninvertible linear discrete-time systems in Banach spaces. Characterizations of these concepts are obtained from the point of view of the projections sequences. Some illustrative examples are given in order to prove that these concepts are distinct.
The Bandwidths of a Matrix. A Survey of Algorithms
Authors: Mafteiu-Scai Liviu Octavian 
Published: March 2015

AbstractThe bandwidth, average bandwidth, envelope, profile and antibandwidth of the matrices have been the subjects of study for at least 45 years. These problems have generated considerable interest over the years because of them practical relevance in areas like: solving the system of equations, finite element methods, circuit design, hypertext layout, chemical kinetics, numerical geophysics etc. In this paper a brief description of these problems are made in terms of their definitions, followed by a comparative study of them, using both approaches: matrix geometry and graph theory. Time evolution of the corresponding algorithms as well as a short description of them are made. The work also contains concrete real applications for which a large part of presented algorithms were developed.
Biochemical soil activity in Taxus baccata L. stands in forest reserves and managed forests
Authors: Olszowska Grażyna 
Published: March 2015

Abstract
The aim of these studies was to estimate the enzymatic activity and chemical properties of soils of Taxus baccata L. stands in selected forest reserves as well as in managed forest stands that do not belong to reserves. Furthermore, I compared the soil fertility of both types of forest stand using a biochemical soil quality indicator. The studies were conducted in the following reserves: ‘Bogdanieckie Cisy’, ‘Cisy Rokickie’, ‘Cisy Tychowskie’, ‘Cisy w Czarnem’, as well as in managed forest stands with the same soil and habitat type as the above-mentioned reserves. Analyses showed a lower activity of urease, asparaginase, acid phosphatase and dehydrogenase in soils of the managed forests than in soils of the reserves. The soil nutrient availability given by the total organic carbon, nitrogen, and alkaline cation content as well as soil sorption capacity were significantly lower outside the forest reserves. Chemical and biochemical parameters were used to calculate a biochemical index of soil fertility. The index was higher for soil in forest reserves than for soil in managed forest stands located outside reserves. The result held true regardless of the biochemical parameters used in calculation. As has been shown in previous studies on protected areas with no cultivation that are largely influenced by natural processes, biochemical indices can be very useful for comparative analyses aiming at estimating soil quality or the reaction of soil to external factors, both natural and anthropogenic

AbstractUsing in situ data from 2011 and 2013, we evaluate the ability of CryoSat-2 (CS-2) to retrieve sea-ice freeboard over fast ice in McMurdo Sound. This provides the first systematic validation of CS-2 in the coastal Antarctic and offers insight into the assumptions currently used to process CS-2 data. European Space Agency Level 2 (ESAL2) data are compared with results of a Waveform Fitting (WfF) procedure and a Threshold-First-Maximum-Retracker-Algorithm employed at 40% (TFMRA40). A supervised freeboard retrieval procedure is used to reduce errors associated with sea surface height identification and radar velocity in snow. We find ESAL2 freeboards located between the ice and snow freeboard rather than the frequently assumed snow/ice interface. WfF is within 0.04 m of the ice freeboard but is influenced by variable snow conditions causing increased radar backscatter from the air/snow interface. Given such snow conditions and additional uncertainties in sea surface height identification, a positive bias of 0.14 m away from the ice freeboard is observed. TFMRA40 freeboards are within 0.03 m of the snow freeboard. The separation of freeboard estimates is primarily driven by the different assumptions of each retracker, although waveform alteration by variations in snow properties and surface roughness is evident. Techniques are amended where necessary, and automatic freeboard retrieval procedures for ESAL2, WfF and TFMRA40 are presented. CS-2 detects annual fast-ice freeboard trends using all three automatic procedures that are in line with known sea-ice growth rates in the region.
Radiographic and computed tomographic assessment of the development of the antebrachia and elbow joints in Labrador Retrievers with and without medial coronoid disease
Authors: Hazewinkel H. A. W. , Voorhout G. , Lau S. F. 
Published: March 2015

SummaryObjectives: To compare the development, monitored by radiography and computed tomography, of the antebrachia and elbow joints in seven Labrador Retrievers with healthy elbow joints and in seven Labrador Retrievers that developed medial coronoid disease (MCD), in order to determine whether disturbances in the development of the antebrachia and elbow joints, between the age of six and 17 weeks may lead to medial coronoid disease.Methods: A prospective study of 14 Labrador Retrievers in their active growth stage was performed. The development of the antebrachia and elbow joints was assessed between six and 17 weeks of age using radio graphy and computed tomography determining the development of secondary ossification centres, radioulnar length ratio, radial angulation, and inter-relationship between the humerus, ulna and radius.Results: For the parameters of ossification of secondary ossification centres, radioulnar length ratio, radial angulation, and joint congruence evaluation, there was no significant difference in the development of the ante-brachia and elbow joints of seven Labrador Retrievers positive and seven Labrador Retrievers negative for MCD at the age of six to 17 weeks.Clinical significance: These findings demonstrate that the development of MCD in the Labrador Retrievers in our study was not related to any disturbance in the development of the antebrachia and elbow joints during the rapid growth phase.
Le renforcement du centre de l’exécutif : Expliquer le changement autrement que par le NMP
Authors: Kolltveit Kristoffer 
Published: March 2015

Dans plusieurs pays, diverses mesures ont été prises en vue d’améliorer la capacité de coordination et de contrôle de la politique publique au sein du centre de l’exécutif. La littérature sur l’ensemble du gouvernement (« whole-of-government ») et le gouvernement décloisonné considère ces évolutions comme une réaffirmation des initiatives visant à contrer les effets négatifs des anciennes réformes du NMP. La principale question de recherche examinée dans le présent article est celle de savoir si le renforcement du centre de l’exécutif doit aussi s’expliquer par les évolutions plus larges dans la société et par les caractéristiques du gouvernement proprement dit. Nous tâcherons de répondre à cette question en examinant les évolutions survenues en Norvège depuis trente ans. Même si les anciennes réformes du NMP jouent un rôle dans le cas de la Norvège, nous verrons dans cet article que les mesures prises doivent aussi s’expliquer par le désir d’améliorer le processus décisionnel du gouvernement et de résoudre les conflits entre les partis qui le composent. Remarques l’intention des praticiens Dans le présent article, nous examinons différentes explications de l’évolution survenue au sein du centre de l’exécutif en Norvège. Au cours des trente dernières années, le centre de l’exécutif norvégien s’est renforcé grâce au nombre accru de personnes désignées pour des raisons politiques au sein des ministères, mais aussi de l’élargissement du bureau du Premier ministre, où un ministre de la Coordination a été désigné en 2009, et de l’officialisation d’un cabinet restreint. Les données empiriques sont extraites de documents ministériels internes et d’entretiens semi-structurés réalisés avec des responsables administratifs et politiques. Nous verrons que les évolutions en Norvège ont plusieurs explications, ce qui tend à indiquer que les changements survenus au sein du centre de l’exécutif sont hétérogènes et sont rarement réalisés dans un but unique.

Published: March 2015

Purpose. In the United States, 36% of human papillomavirus (HPV)–related cancers occur among men. HPV vaccination can substantially reduce the risk of HPV infection; however, the vast majority of men are unvaccinated. This study developed and validated transtheoretical model–based measures for HPV vaccination in young adult men. Design. Cross-sectional measurement development. Setting. Online survey of young adult men. Subjects. Three hundred twenty-nine mostly college-attending men, ages 18 to 26. Measures. Stage of change, decisional balance (pros/cons), and self-efficacy. Analysis. The sample was randomly split into halves for exploratory principal components analysis (PCA), followed by confirmatory factor analyses (CFA) to test measurement models. Multivariate analyses examined relationships between scales. Results. For decisional balance, PCA revealed two uncorrelated five-item factors (pros α = .78; cons α = .83). For the self-efficacy scale, PCA revealed a single-factor solution (α = .83). CFA confirmed that the two-factor uncorrelated model for decisional balance and a single-factor model for self-efficacy. Follow-up analyses of variance supported the theoretically predicted relationships between stage of change, pros, and self-efficacy. Conclusion. This study resulted in reliable and valid measures of pros and self-efficacy for HPV vaccination that can be used in future clinical research.

On characteristics of social disorder and resistance
Recent scientific literature and media focus on new styles, rituals and instruments in the phenomena of social disorder and resistance. People fight for new issues, in changing in/out group settings, with social media as a means to an end that often is not so obvious from the start. The various, dynamic local contexts define how and why these new ambitions and techniques become trenchant.From a long term perspective patterns and appearances do change, but (perceived) distributive injustice and procedural injustice remain the key drivers motivating social disorder and resistance. Feeding on recent studies about the immediate aftermath of the Second World War (1945), the Arab Spring (2010-2011), and the British ‘Summer of Discontent’ (2011), this article reconsiders the question: what’s new?
A large‐scale view of Space Technology 5 magnetometer response to solar wind drivers

Published: March 2015

AbstractIn this data report we discuss reprocessing of the Space Technology 5 (ST5) magnetometer database for inclusion in NASA's Coordinated Data Analysis Web (CDAWeb) virtual observatory. The mission consisted of three spacecraft flying in elliptical orbits, from 27 March to 27 June 2006. Reprocessing includes (1) transforming the data into the Modified Apex Coordinate System for projection to a common reference altitude of 110 km, (2) correcting gain jumps, and (3) validating the results. We display the averaged magnetic perturbations as a keogram, which allows direct comparison of the full‐mission data with the solar wind values and geomagnetic indices. With the data referenced to a common altitude, we find the following: (1) Magnetic perturbations that track the passage of corotating interaction regions and high‐speed solar wind; (2) unexpectedly strong dayside perturbations during a solstice magnetospheric sawtooth oscillation interval characterized by a radial interplanetary magnetic field (IMF) component that may have enhanced the accompanying modest southward IMF; and (3) intervals of reduced magnetic perturbations or “calms,” associated with periods of slow solar wind, interspersed among variable‐length episodic enhancements. These calms are most evident when the IMF is northward or projects with a northward component onto the geomagnetic dipole. The reprocessed ST5 data are in very good agreement with magnetic perturbations from the Defense Meteorological Satellite Program (DMSP) spacecraft, which we also map to 110 km. We briefly discuss the methods used to remap the ST5 data and the means of validating the results against DMSP. Our methods form the basis for future intermission comparisons of space‐based magnetometer data.

AbstractThe paper reports a clear dependence of a basic structure of two sublayers of the low‐latitude boundary layer (LLBL) on northward and southward interplanetary magnetic field (IMF) orientations. Regardless of different processes responsible for a formation and evolution of the entire LLBL, the outer part of the LLBL is significantly influenced by the sign of the IMF BZ component. Under northward IMF conditions this layer is present, whereas it is missing during a southward pointing IMF. This behavior can be understood in terms of a motion of reconnection spots due to the changes of the orientation of the magnetosheath magnetic field in the vicinity of the magnetopause. Our case and statistical studies demonstrate that the changes of the LLBL structure can be observed in the subsolar region as well as on flanks near the dawn‐dusk meridian. Moreover, the study emphasizes a role of magnetosheath magnetic field variations on the boundary layer formation.
A computational and theoretical investigation of nonlinear wave‐particle interactions in oblique whistlers
Authors: Nunn David , Omura Yoshiharu 
Published: March 2015

AbstractMost previous work on nonlinear wave‐particle interactions between energetic electrons and VLF waves in the Earth's magnetosphere has assumed parallel propagation, the underlying mechanism being nonlinear trapping of cyclotron resonant electrons in a parabolic magnetic field inhomogeneity. Here nonlinear wave‐particle interaction in oblique whistlers in the Earth's magnetosphere is investigated. The study is nonself‐consistent and assumes an arbitrarily chosen wave field. We employ a “continuous wave” wave field with constant frequency and amplitude, and a model for an individual VLF chorus element. We derive the equations of motion and trapping conditions in oblique whistlers. The resonant particle distribution function, resonant current, and nonlinear growth rate are computed as functions of position and time. For all resonances of order n, resonant electrons obey the trapping equation, and provided the wave amplitude is big enough for the prevailing obliquity, nonlinearity manifests itself by a “hole” or “hill” in distribution function, depending on the zero‐order distribution function and on position. A key finding is that the n = 1 resonance is relatively unaffected by moderate obliquity up to 25°, but growth rates roll off rapidly at high obliquity. The n = 1 resonance saturates due to the adiabatic effect and here reaches a maximum growth at ~20 pT, 2000 km from the equator. Damping due to the n = 0 resonance is not subject to adiabatic effects and maximizes at some 8000 km from the equator at an obliquity ~55°.
Processes controlling mid‐water column oxygen minima over the Texas‐Louisiana shelf

Published: March 2015

AbstractWe investigate distributions of dissolved oxygen over the Texas‐Louisiana shelf using spatially highly resolved observations in combination with a regional circulation model with simple oxygen dynamics. The observations were collected using a towed, undulating CTD during the Mechanisms Controlling Hypoxia (MCH) program. Mid‐water oxygen minimum layers (dissolved oxygen lower than 3.2 mL L−1) were detected in many transects. These oxygen minimum layers are connected with the bottom boundary layer and follow the pycnocline seaward as a tongue of low oxygen into the mid‐water column. T‐S diagrams highlighting the low oxygen minima in both observations and simulations imply direct connections between low‐oxygen bottom water and the oxygen minimum layer. The dynamics of these oxygen minimum layers in the mid‐water column are examined using a three‐dimensional hydrodynamic model, based on the Regional Ocean Modeling System (ROMS). Convergence within the bottom boundary layer relative to density surfaces is calculated, results show that there is a convergence in the bottom boundary layer at the location where the pycnocline intersects the bottom. Buoyancy advection forced by bottom Ekman transport creates this convergent flow, and the corresponding low‐oxygen intrusion. Similar intrusions of near‐bottom water into the pycnocline are observed in other regions. The presence of hypoxia within the bottom boundary layer in the northern Gulf of Mexico creates a unique situation in which these intrusions are also associated with low dissolved oxygen.
