Kommunikationsformenadressen oder: Prozeduren des Situationsvollzugs am Beispiel von Weblogs
Authors: Meiler Matthias 
Published: December 2013

Abstract
Using the example of weblogs the paper raises the question what kind ofprocedures are necessary to enable speech acts (written or spoken), pictures(moving or static), typography, layout, etc. – i.e., procedures thatare considered to be possibility conditions for acts of communication. Toanswer that question a category from early Textual Linguistics – Formsof Communication (initially: Ermert 1979) – is reconstructed in its developmentthroughout the history of Textual and Media Linguistics (cf.Brinker 6[1985] 2005; Dürscheid 2005; Holly 1996, 2011b; Domke 2010a)and is reconceptualized with a more pragmatic resp. praxeological approach.In order to do this, the concept of Speech Procedures – developedby the Functional Pragmatics approach (cf. Ehlich [1986] 1991) – ischosen, conceptually located, and adapted to enable a description that addressesall the actions which establish – quite simultaneously to acts ofcommunication – the possibility to communicate and which are clusteredand differentiated as Medializing and Addressing Procedures. In a bodythey work on the tasks of situating communication in space and time andbetween communicators. Hereby going beyond Genre Theory (cf. e.g.Puschmann 2013), it is possible to conceive of weblogs ever so adequatelyas being situated on an average level of communicational knowledge.

Published: December 2013

Abstract
Objective—To identify factors significantly associated with prognosis in cats hospitalized because of pancreatitis.
Design—Prospective case series.
Animals—33 cats hospitalized for treatment of pancreatitis (diagnosis determined on the basis of clinical signs and serum feline pancreatic lipase immunoreactivity [fPLI] concentration ≥ 5.4 μg/L).
Procedures—Cats were hospitalized (day 1) for 2 to 16 days and observed for 44 days or until they died or were euthanized. Results of physical examination and hematologic and serum biochemical analysis, including measurement of serum fPLI concentration, performed on the day of hospital admission were analyzed to determine whether they were associated with outcome (ie, survival to at least 44 days vs death or euthanasia).
Results—On day 1, mean × SD serum fPLI concentration among the 33 cats was 22.0 × 16.4 μg/L. Mean age of the cats was 12.7 × 3.8 years (range, 4 to 19 years). Eleven of the 33 (33%) cats died or were euthanized before day 44. In univariate analyses, dyspnea, hypothermia, hypokalemia, hyperkalemia, and serum fPLI concentration were significantly associated with an adverse outcome. However, in a multivariate analysis, only severe dyspnea, hyperkalemia (potassium concentration > 5.5 mmol/L), and serum fPLI concentration at the time of hospital admission were found to be significantly associated with an adverse outcome.
Conclusions and Clinical Relevance—Results suggested that dyspnea, hyperkalemia, and serum fPLI concentration at the time of hospital admission were significant prognostic factors for cats hospitalized because of pancreatitis.
Diagnostic accuracy of a point-of-care urine bacteriologic culture test in dogs
Authors: Olin Shelly J. , Bartges Joseph W. , Jones Rebekah D. , Bemis David A. 
Published: December 2013

Abstract
Objective—To determine diagnostic accuracy of a compartmented bacteriologic culture and antimicrobial susceptibility testing plate (CCSP) for detection of bacterial urinary tract infection (UTI) in dogs and antimicrobial susceptibility testing of bacterial isolates.
Design—Evaluation study.
Sample—62 frozen, previously characterized bacterial isolates from canine urine cultures and 147 canine urine samples.
Procedures—The study was conducted in 2 phases: preliminary assay validation (phase 1) and diagnostic validation (phase 2). For phase 1, the frozen bacterial isolates were revitalized and tested with the CCSP and with standard aerobic microbiological culture (SAMC). For phase 2, the urine samples were tested with the CCSP and SAMC in parallel.
Results—For phase 1, after 24 hours of culture, 46 of 62 (74%) bacterial isolates had growth on the CCSP and all (100%) had growth in SAMC. For bacterial isolates with growth, the CCSP allowed correct identification of 45 of 46 (98%) isolates. Isolates yielding no growth on the CCSP were gram-positive cocci (Staphylococcus spp [n = 7] and Enterococcus spp [9]). In phase 2, the overall diagnostic accuracy of the CCSP, compared with SAMC, was 94% (sensitivity, 81%; specificity, 99%). The positive predictive value was 98% and negative predictive value was 92%. Susceptibility results for enrofloxacin and trimethoprim-sulfamethoxazole as determined with the CCSP had greatest concordance with those determined by SAMC (71% and 96%, respectively), compared with other antimicrobial susceptibilities.
Conclusions and Clinical Relevance—Use of the CCSP led to accurate exclusion of UTI in dogs without a UTI but was less reliable for diagnosis of UTI, particularly infections caused by gram-positive cocci. Standard aerobic microbiological culture remains the gold standard for detection of UTI in dogs.
Symmetric Neutral-Atmosphere Mapping Functions: A Review of the State-Of-The-Art
Authors: Sharifi M.A. , Souri A.H. 
Published: December 2013

ABSTRACT
The aim of this paper is to review of six recent symmetric mapping functions. The mapping function can be largely used for GPS meteorological measurements, InSAR atmospheric corrections and precise measurements of very long baseline interferometry (VLBI). These spacebased techniques use radio signal that propagate through the Earth's atmosphere. The electrically-neutral region, predominantly the troposphere, affects the speed and direction of travel of radio waves leading to existence of excess path. The mapping function models the elevation angle dependence of the delay. Within the past decade, significant improvements have been achieved in order to use of Numerical Weather Models (NWM) for geodetic positioning. Ray-tracing algorithms have been performed through refractivity shells retrieved from NWMs in order to relate zenith delays to slant delays. Therefore, there seems to be a real need for deep review of recent developments in the mapping function domain. This paper proposes a comprehensive review of the symmetric mapping functions state of the art, their spatio-temporal variations and used NWM and generic models. Niell Mapping Function (NMF), Vienna Mapping Function (VMF1), University of New Brunswick-VMF1 (UNB-VMF1) mapping functions, Global Mapping Function (GMF) and Global Pressure and Temperature (GPT2)/GMF are reviewed in this paper.
Controllling Simulation Experiment Design for Agent-Based Models Using Tree Representation of Parameter Space
Authors: Szufel Przemysław , Kamiński Bogumił , Wojewnik Piotr 
Published: December 2013

Abstract
An important aspect of the simulation modelling process is sensitivity analysis. In this process, agent-based simulations often require analysis of structurally different parameter specifications - the parameters can be represented as objects and the object-oriented simulation configuration leads to nesting of simulation parameters. The nested parameters are naturally represented as a tree rather than a flat structure. The standard tools supporting multi-agent simulations only allow only the representation of the parameter space as a Cartesian product of possible parameter values. Consequently, their application for the required tree representation is limited. In this paper an approach to tree parameter space representation is introduced with an XML-based language. Furthermore, we propose a set of tools that allows one to manage parameterization of the simulation experiment independently of the simulation model.
Time of concentration of surface flow in complex hillslopes
Authors: Sabzevari Touraj , Saghafian Bahram , Talebi Ali , Ardakanian Reza 
Published: December 2013

Abstract
Time of concentration (TC) of surface flow in watersheds depends on the coupled response of hillslopes and stream networks. The important point in this background is to study the effects of the geometry and the shape of complex hillslopes on the time of concentration considering the degree of flow convergence (convergent, parallel or divergent) as well as the profile curvature (concave, straight or convex). In this research, the shape factor of complex hillslopes as introduced by Agnese et al. (2007) is generalized and linked to the TC. A new model for calculating TC of complex hillslopes is presented, which depends on the plan shape, the type and degree of profile curvature, the Manning roughness coefficient, the flow regime, the length, the average slope, and the excess rainfall intensity. The presented model was compared to that proposed by Singh and Agiralioglu (1981a,b) and Agiralioglu (1985). Moreover, the results of laboratory experiments on the travel time of surface flow of complex hillslopes were used to calibrate the model. The results showed that TC for convergent hillslopes is nearly double those of parallel and divergent ones. TC in convex hillslopes was very close to that in straight and concave hillslopes. While the effect of convergence on TC is considerable, the curvature effect confirmed insignificant. Finally, in convergent hillslopes, TC increases with the degree of convergence, but in divergent hillslopes, it decreases as degree of divergence increases.
The use of sodium polytungstate as an X-ray contrast agent to reduce the beam hardening artifact in hydrological laboratory experiments
Authors: Nakashima Yoshito 
Published: December 2013

Abstract
Iodine is conventionally used as a contrast agent in hydrological laboratory experiments using polychromatic X-ray computed tomography (CT) to monitor two-phase Darcy flow in porous geological media. Undesirable beam hardening artifacts, however, render the quantitative analysis of the obtained CT images difficult. CT imaging of porous sand/bead packs saturated with iodine and tungsten-bearing aqueous solutions, respectively, was performed using a medical CT scanner. We found that sodium polytungstate (Na6H2W12O40) significantly reduced the beam hardening compared with potassium iodide (KI). This result is attributable to the location of the K absorption edge of tungsten, which is nearer to the peak of the polychromatic X-ray source spectrum than that of iodine. As sodium polytungstate is chemically stable and less toxic than other heavy element bearing compounds, we recommend it as a promising contrast agent for hydrological CT experiments.
Changing Media Preferences?
Authors: Näsi Matti , Räsänen Pekka 
Published: December 2013

Abstract
As the Internet provides extensive sources of information and entertainment platforms, traditional forms of media have come under scrutiny ever since the early days of the information and communication technologies (ICTs). In the present article, we examine how media preferences in Finland have changed over the past ten years by focusing on the perceived importance of television, newspapers and the Internet. We use three sets of nationally representative survey data from 1999, 2004 and 2009, respectively, to establish a comparative view of the preferences during this time. Our findings indicate that even though the perceived importance of the Internet has increased during the past ten years, media preferences in general have not changed radically. In addition, we are able to witness clear variations between socio-demographic groups across all points in time. Some of these variations have weakened over time, but not all of them. Broader implications for a changing media landscape are discussed in relation to the results.
Contribution to the knowledge of the parasitic fauna of fish off Adelie Land, Antarctica
Authors: Zdzitowiecki Krzysztof , Ozouf−Costaz Catherine 
Published: December 2013

Abstract
In total, 42 fish belonging to 16 species were examined. All fish were infected. Parasitic worms were endoparasites: Digenea (eight species), Cestoda (three mixed groups of larval forms), Acanthocephala (two species) and Nematoda (one species in adult and one in larval stage, and two Contracaecum spp. in larval stage). Undetermined parasitic Copepoda and Hirudinea were external parasites. Summing up previous and new data 25 species and mixed groups were found. Parasites in larval stage using fish as intermediate or paratenic hosts were more numerous than species maturing in fish. For example, 1913 nematodes Contracaecum spp. were recorded in one fish, whereas the digenean, Genolinea bowersi, was the most numerous maturing parasite (168 specimens in one fish).

Abstract
Whole-grain rye intake has been suggested to have anti-cancer effect, including changes in serum hormones and reduced prostate specific antigen (PSA) in animals and humans. In this study, we investigated the effect of high intake of whole-grain rye bread on prostate cancer progression as assessed by PSA concentration in men diagnosed with prostate cancer. Fifteen men with prostate cancer who did not receive prior therapy were randomised and given a daily supplement of 250 g refined wheat bread for two weeks and, afterwards, 250 g whole-grain rye bread for six weeks. Blood samples were taken from fasting men at baseline and after two and six weeks to measure the PSA and sex hormones. The dietary intake was: energy intake 3452 kcal; protein intake 166 g, carbohydrate intake 334 g, fat 149 g, saturated fat intake 52 g, and fibre intake 40 g. Plasma total PSA, free PSE, testosterone concentrations and free androgen index tended to be higher after refined white bread treatment and lower after whole-grain rye treatment. However, none of the differences were statistically significant. There were no significant changes in sex hormone binding globulin, luteinising hormone, and follicle stimulating hormone. In this intervention trial, whole-grain rye consumption did not result in significant changes in PSA and sex hormones, which may be related to high fat intake. Further prospective trials are indicated to evaluate the potential of whole-grain rye bread, taking into account other factors.
Effect of the Glonass-Specific Receiver Antenna Phase Center Corrections on the Results of European Regional GNSS Network
Authors: Liwosz Tomasz 
Published: December 2013

ABSTRACT
In the paper I investigated the effect of the GLONASS-specific receiver antenna phase center corrections on the results of a regional permanent GNSS network. I made analysis, using Bernese GPS Software 5.0, of GPS-only and GPS-GLONASS (GNSS) observations collected at permanent sites in Europe. Two types of GNSS solutions were computed: with GPS phase center corrections used for observations of both systems, and with the system specific corrections for observations of the respective system. The Bernese software was modified accordingly to use GLONASS specific corrections for GLONASS measurements. The results, i.e., coordinates and tropospheric zenith delays were analyzed and compared between computed solutions. Introducing GLONASS-specific receiver antenna phase center corrections did not improve the repeatability of the GNSS coordinate time series. Differences of coordinates between the two GNSS solutions were highly repeatable but offsets (biases) were observed; maximum bias for horizontal component was 1 mm and 4 mm for up component. Similar biases were observed for stations with the same antenna models. Periodic signal with a period of 1/3-year was found in difference time series between GPS and GNSS solutions for north component with a maximum peak-to-peak amplitude 2.8 mm. The periodic signal was attributed to GLONASS.

Wood supply for the Aubrugg wood-fired combined heating-and-power-plant by Zürich Holz AG – experience so far
The article addresses wood supply for a large heating plant in Switzerland, delivered by Zürich Holz AG. It describes the role of the supplier, in this case a wood marketing company, owned by the forest owners, in preparing and delivering the contracted volumes. Important factors in the success (so far) of the supply system are the reliable supply of the contracted volumes by the suppliers as well as careful organisation and monitoring of deliveries. The commercial success is based on systematic reference to the energy content of the wood. The article also addresses the measures put in place to guard against possible future reductions in wood availability.
Entwicklungstrends der Holzenergie und ihre Rolle in der Energiestrategie 2050
Authors: Nussbaumer Thomas 
Published: December 2013

Perspectives of biomass combustion and its role in the energy strategy 2050
Wood energy contributes 4% to the total energy demand in Switzerland and is expected to reach 6% by 2020. As a directly storable fuel, energy wood is highly valuable to complement temporarily available solar and wind energy. Since the potential of wood is limited, highly effective applications to substitute fossil fuels need to be prioritised. For this, the energy yield factor is introduced, which reveals that heat and power from wood achieve a high substitution efficiency enabling a reduction of fossil CO2 of up to 90%. Consequently, the unused potential of energy wood should be mobilised for heating, disctrict heat, and combined heat and power (CHP). For these applications, the following developments need to be carried on: small-scale devices with low pollutant emissions by two-stage combustion, stringent execution of air pollution control to avoid inappropriate operation, improvements of grate boilers by aerodynamic optimisation, sectoral fuel conversion, and reduction of fuel NOX emissions by advanced staged combustion. With respect to power from wood, technologies with reduced cost for applications smaller than 1 MWe must be developed, while for low-quality wood fuels, a limited number of highly efficient plants based on Integrated Gasification Combined Cycle (IGCC) is most promising. The findings reveal that the assumptions for the Swiss energy strategy 2050 with a decline of energy wood for heat by 60% and a shift to biofuels are not justified, since wood for heat, power, and CHP achieves higher energy yields with technologies which are available or ready to implementation (IGCC) and economically viable.
Intensivere Holzenergienutzung in Europa: Politik- und Forschungsaspekte

Published: December 2013

Increased use of wood energy in Europe: policy and research issues
The contrasting and often conflicting objectives associated with the increased use of bioenergy resources pose significant political and regulatory challenges across Europe. In the EU, wood energy use is not regulated in a dedicated directive, but is part of a variety of directives with different foci, and the individual EU member states implement these directives in very different ways. The challenges lie, on the one hand, in the harmonization of policies, standards and regulation and, on the other hand, in measures for efficiency improvements and minimization of adverse side effects of wood energy use. In this paper, the current EU bioenergy and wood energy legislative framework and specific policies are presented and current research themes in the context of the European wood energy policy highlighted, with a special emphasis on cascadic use of wood resources. It can be concluded that sustainable material and energy use of wood is subject to many restrictions, and that although cascadic use contributes to resource efficiency and CO2 mitigation, it may also affect the prevailing market structures significantly.
A Skolem–Mahler–Lech Theorem for Iterated Automorphisms ofK–algebras

AbstractIn this paper we prove a commutative algebraic extension of a generalized Skolem–Mahler– Lech theorem. LetAbe a finitely generated commutativeK–algebra over a field of characteristic 0, and letσbe aK–algebra automorphism ofA. Given idealsIandJofA, we show that the setSof integersmsuch thatJis a finite union of complete doubly infinite arithmetic progressions inm, up to the addition of a finite set. Alternatively, this result states that for an affine schemeXof finite type overK, an automorphismσ∊ 2 AutK(X), andYandZany two closed subschemes ofX, the set of integersmwithYis as above. We present examples showing that this result may fail to hold if the affine schemeXis not of finite type, or ifXis of finite type but the fieldKhas positive characteristic.
Spectral Aspects of the Skew-Shift Operator: A Numerical Perspective
Authors: Bourgain-Chang Eric 
Published: December 2013

AbstractIn this paper we perform a numerical study of the spectra, eigenstates, and Lyapunov exponents of the skew-shift counterpart to Harper’s equation. This study is motivated by various conjectures on the spectral theory of these ‘pseudo-random’ models, which are reviewed in detail in the initial sections of the paper. The numerics carried out at different scales are within agreement with the conjectures and show a striking difference compared with the spectral features of the Almost Mathieu model. In particular our numerics establish a small upper bound on the gaps in the spectrum (conjectured to be absent).

ABSTRACT
The ever-increasing problem of cultural heritage destruction in the eastern Mediterranean is the topic for this Forum. With the rapid spread of armed conflict and civil uprising throughout the Middle East and North Africa, the protection of cultural property takes a backseat to more pressing concerns about the destruction of lives and economic resources. In this article and the responses that follow, the complexities of preserving the past in the context of a volatile present are explored.
