Abstract
We report the CH4 emission flux from the city of Indianapolis, IN, the site of the Indianapolis Flux Experiment (INFLUX) project for developing, assessing, and improving top-down and bottom-up approaches for quantifying urban greenhouse gas emissions. Using an aircraft-based mass balance approach, we find that the average CH4 emission rate from five flight experiments in 2011 is 135 ± 58 (1σ) moles s-1 (7800 ± 3300 kg hr-1). The effective per capita CH4 emission rate for Indianapolis is 77 kg CH4 person-1 yr-1, a figure that is less than the national anthropogenic CH4 emission (∼91 kg CH4 person-1 yr-1) but considerably larger than the global figure (∼48 kg CH4 person-1 yr-1). We consistently observed elevated CH4 concentrations at specific coordinates along our flight transects downwind of the city. Inflight investigations as well as back trajectories using measured wind directions showed that the elevated concentrations originated from the southwest side of the city where a landfill and a natural gas transmission regulating station (TRS) are located. Street level mobile measurements downwind of the landfill and the TRS supported the results of aircraft-based data, and were used to quantify the relative contributions from the two sources. We find that the CH4 emission from the TRS was negligible relative to the landfill, which was responsible for 33 ± 10% of the citywide emission flux. A regression of propane versus methane from aircraft flask samples suggests that the remaining citywide CH4 emissions (∼67%) derive from the natural gas distribution system. We discuss the combination of surface mobile observations and aircraft city-wide flux measurements to determine the total flux and apportionment to important sources.

A poor response to chemotherapy (≤ 90% necrosis) for osteosarcomas leads to poorer survival and an increased risk of local recurrence, particularly if there is a close margin of excision. We evaluated whether amputation confers any survival benefit over limb salvage surgery (LSS) with narrow margins in patients who respond poorly to chemotherapy. We only analysed patients with an osteosarcoma of the limb, a poor response to chemotherapy and close margins on LSS (marginal/intralesional) or primary amputation: 360 patients (36 LSS (intralesional margins), 197 LSS (marginal margins) and 127 amputations) were included. Local recurrence developed in 13 (36%) following LSS with intralesional margins, and 39 (20%) following LSS with marginal margins. There was no local recurrence in patients who underwent amputation. The five-year survival for all patients was 41% (95% confidence interval (CI) 35 to 46), but for those treated by LSS with marginal margins was 46.2% (95% CI 38 to 53), 36.3% (95% CI 27 to 45) for those treated by amputation, and 28% (95 CI 14 to 44) for those treated by LSS with intralesional margins. Patients who had LSS and then developed local recurrence as a first event had the same survival as those who had primary amputation without local recurrence. Prophylactic adjuvant radiotherapy was used in 40 patients but had no discernible effect in preventing local recurrence. Although amputation offered better local control, it conferred no clear survival benefit over LSS with marginal margins in these patients with a poor overall prognosis.

Published: January 2015

Abstract
Succinylcholine is one of the most commonly used drugs by anesthesiologists worldwide for rapid access to airway both in emergency and elective situations. Nonetheless, the very mention of succinylcholine generates the most energetic high decibel debate between its users and nonusers. Despite its potential to produce a short-acting, ultra-intense neuromuscular block rapidly in seconds, it is surrounded by a plethora of side effects and drug interactions. This case report is about one such drug interaction of this innocent yet malicious drug, which resulted in the death of a 14-year-old girl. Both β-adrenergic blockers and succinylcholine are known to cause hyperkalemia. Life-threatening hyperkalemia in susceptible individuals who have been administered succinylcholine has the most severe effect on the myocardium and can result in asystole with minimal chances of resuscitation. Both succinylcholine and a nonselective β-adrenergic blocker, propranolol, have the propensity to affect the transcellular redistribution of potassium which can result in hyperkalemia. We advocate cautious use of this drug combination till further studies confirm the drug interaction and find the potential triggering factors involved.
Trends in publications on complementary and alternative medicine in the medical literature
Authors: Treister-Goltzman Yulia , Peleg Roni 
Published: January 2015

Abstract

Background: Public interest in and demand for complementary and alternative medicine (CAM) services have increased in recent years throughout the Western world. The aim of the study was to assess trends in publications on CAM in the medical literature between 1963 and 2012 and to compare them with overall trends in publications on medical issues.

Methods: A search of the literature was conducted on CAM and integrative medicine using the PubMed and Google Scholar search engines with key search terms.

Results: Articles on CAM began to appear in the medical literature 50 years ago. Over the years there has been an increase in the number of publications. On PubMed the increase was from 15,764 to 144,288 articles from 1963 to 2012. In the decade between 1963 and 1972 publications on CAM comprised 0.81 % of all the articles appearing in PubMed. Over the course of the 50 years, the percentage increased more than twofold to 1.92 % from 2003 to 2012. On Google Scholar there were 27,170 citations related to CAM between 1963 and 1972. This increased to 2,521,430 between 2003 and 2012.

Conclusions: Over the last 50 years there has been an increase in scientific publications on CAM in general, and on specific CAM treatments in particular.
Tensions, ambivalence, and contradiction: a small story analysis of discursive identity construction in the South African workplace
Authors: Oostendorp Marcelyn , Jones Tamiryn 
Published: January 2015

Abstract
Recently there has been an increased focus on narratives produced within or about the workplace. A number of different analytical approaches to narrative exist and there has been quite a vigorous debate between researchers interested in life stories (or so-called big stories) and those researchers proposing an increased focus on small stories. This paper will use small story analysis (SSA) to examine workplace identity in discourses on organizational processes in one workplace in South Africa. The data for this study were collected by conducting interviews and focus group discussions with 19 members of a large South African retail company. We find that participants often introduce small stories which offer discourses that contradict or contest “official” company discourses (or the so-called sanctioned grand narrative stories). We argue that small stories can be a valuable resource to investigate organizational discourses, as participants often introduce questions of identity which do not necessarily fit the dominant organizational discourses through small stories. Small story analysis seems to be an ideal tool to investigate contradictions and inconsistencies which occur in all discourses but are typical of contexts of diversity and transformation such as the South African workplace.
Cylindrospermopsin: cyanobacterial secondary metabolite. Biological aspects and potential risk for human health and life
Authors: Adamski Michał , Chrapusta Ewelina , Bober Beata , Kamiński Ariel , Białczyk Jan 
Published: January 2015

Abstract
Cylindrospermopsin (CYN) is a cytotoxin produced by several species of cyanobacteria, which occur all over the world. It was demonstrated that CYN has a wide spectrum of biological activity in animal cells, involving hepatotoxicity, genotoxicity, cytotoxicity and carcinogenic potential, and is considered as one of the factors that caused human poisoning in Palm Island (Australia) and in Caruaru (Brazil). This compound may be introduced into organism by several ways, including consumption of water, fishes and seafood as well as accidental swallowing or aerosol spray inhalation during recreational using of reservoirs covered by cyanobacterial blooms. The information about the CYN impact on environment and its degradation processes under natural conditions is scant. Taking this into consideration CYN should be regarded as a potential threat to human health and life. This review presents physicochemical characteristic and biological activity of CYN, occurrence in freshwaters and its sensitivity to the influence of some environmental factors.
Morphology, ecology and distribution of the diatom (Bacillariophyceae) species Simonsenia delognei (Grunow) Lange-Bertalot
Authors: Witkowski Andrzej , Żelazna-Wieczorek Joanna , Solak Cüneyt , Kulikovskiy Maxim 
Published: January 2015

Abstract
Simonsenia delognei is a diatom species which is relatively rarely recorded, but apparently widespread in Europe and other continents. This taxon has recently been discovered for the first time in springs of Central Poland, where it was found to occur abundantly. Somewhat later this species has also been identified and photographed in samples from the Eagean Region in Turkey. Light and electron microscopic studies were carried out on S. delognei populations from the Quaternary spring located near Łódź (Central Poland) and from the Porsuk and Felent Rivers and a spring in the Türkmen Mountains in Kütahya and Havuzdere Stream in Yalova (NW Turkey). Morphological studies were accompanied by environmental measurements and determination of changes in the seasonal distribution of S. delognei in a key area, i.e. the Porzeczkowe spring in Central Poland, which are included in the present study. Identification of S. delognei under a light microscope is difficult and hence an electron microscope is required for accurate taxonomic identification.
New localities of rare species Kobayasiella okadae (Skvortzov) Lange-Bert. and K. tintinnus Buczkó, Wojtal & Jahn in Europe — morphological and ecological characteristics

Published: January 2015

Abstract
The aim of the present work conducted in the area of Międzyrzeki Strict Nature Reserve in the Roztocze National Park was to show new sites of rare and species new to Poland from the Kobayasiella genus (K. okadae (Skvortzov) Lange-Bert., K. tintinnus Buczkó, Wojtal & Jahn) with regard to morphological and ecological characteristics. Chemical parameters show that investigated habitats are poor and oligotrophic with a low content of chlorides, sulfates and nitrates. K. okadae, K. subtilissima (Cleve) Lange-Bert. and K. tintinnus were found in the studied area. The authors suggest the use of synonym Navicula hoeflerii Cholnoky for the Kobayasiella okadae. LM and SEM images were used in the analysis of the material.

Impact of waterbirds on chemical and biological features of water and sediments of a large, shallow dam reservoir
Authors: Gwiazda Robert , Woźnica Andrzej , Łozowski Bartosz , Kostecki Maciej , Flis Adam 
Published: January 2015

Abstract
Large numbers of Mallard Anas platyrhynchos (max. 10,490 ind.), Black-headed Gull Chroicocephalus ridibundus (max. 3,430 ind.) and Great Cormorant Phalacrocorax carbo (max. 1,449 ind.) were recorded on the Goczałkowice Reservoir, Poland (2,754 ha). Most of the waterbirds occurred in the backwater of this reservoir. The amount of phosphorus and nitrogen loaded by the most numerous waterbirds into Goczałkowice Reservoir was estimated at 958 kg and 2,621 kg, respectively in 2011 and 1,043 kg and 2,793 kg, respectively in 2012. In 2011 and 2012, the waterbirds introduced a considerable amount of phosphorus, nitrogen and a large number of coliforms into the backwater of the reservoir. The concentration of different forms of phosphorus and nitrogen, chlorophyll-a and bacteria coli in the water was not greater at the site of birds’ concentration (except dissolved organic nitrogen). The concentration of nitrates in the water at the site near the breeding colony of gulls in comparison with the reference site was not different. The amounts of P-tot and N-tot in the sediment were similar at the site affected by waterbirds and at the reference site. The dynamics of water masses was not the reason for the lack of differences between the studied sites.
Failure Analysis of a Hydraulic Manifold Plate
Authors: Herz M. , Triesch G. 
Published: January 2015

Abstract
Massive forming requires the use of large costly production facilities. Their degree of utilization plays an important role in price calculation. Direct costs are incurred by disruptions in the production process. Those disruptions should therefore be avoided whenever possible. Any production facility in the field of forming technology aims at maintaining a possibly smooth and efficient operation. Damaged machine parts or components may lead to high consequential costs. However, the costs incurred for the replacement of the defective component merely represent a small fraction of the overall incurred costs.

Published: January 2015

Abstract
This work presents quantitative microstructures and triboelectric properties of melt-infiltrated copper-graphite composites which are characterized by a specific structural composition. It compares them with commercially available carbon brush material. The structural design requires the synthesis of open porous graphite preforms. This work reports on advances in the powder preparation and the production of composites by means of direct squeeze casting. A specially developed tribo-electric testing device is presented. It is used to simultaneously test tribological, thermal, as well as electrical influences.
Development and characterization of microsatellite loci in the mistletoe Psittacanthus schiedeanus (Loranthaceae)
Authors: González Clementina , Harvey Nick , Ornelas Juan Francisco 
Published: January 2015

• Premise of the study: Microsatellite primers were developed for the parasitic Psittacanthus schiedeanus, a common mistletoe species on cloud forest–adapted tree hosts in Mesoamerica, to investigate intraspecific genetic patterns of diversity and genetic structure.• Methods and Results: Using an enriched library, 10 polymorphic microsatellite loci were developed in P. schiedeanus. All loci consisted of dinucleotide repeats. Average alleles per locus were 12 (4–17), and a total of 120 alleles were recorded across 39 individuals from four populations in Mexico. Primers were tested in 11 additional species, but only amplified successfully in P. calyculatus and P. angustifolius.• Conclusions: The polymorphic loci described will be useful in studies of genetic diversity and genetic population differentiation in natural populations of these parasitic plants, and will provide valuable information to understand the importance of host distribution.

Accéder aux textes juridiques de son secteur d’activité est certes essentiel, mais vous êtes perdu. Pourtant, le paysage qui s’offre à vous n’est pas aussi confus que vous l’imaginiez. Il n’est pas inutile de rappeler que le célèbre adage attribué à Aristote, « Nul n’est censé ignorer la loi » , se poursuit par « surtout quand il est facile de la connaître ». Par ailleurs, diffuser l’information paraît être une mission à haut risque tant le hiatus semble grand entre les possibilités techniques et les obligations juridiques.

Médiation thérapeutique picturale et associativité formelle dans les dispositifs pour enfants avec troubles envahissants du développement
Authors: Brun Anne 
Published: January 2015

Cet article vise à décrire la spécificité de la symbolisation et des formes de transfert mises en jeu par la médiation picturale, individuelle ou groupale, avec des enfants souffrant de troubles envahissants du développement, en proposant le concept d’associativité formelle, destiné à repérer l’enchaînement des formes non seulement dans les productions, mais aussi dans l’ensemble du langage sensorimoteur des enfants confrontés au médium. Du fait de cette associativité sensorimotrice, les médiations thérapeutiques comme la peinture favorisent l’émergence de formes primaires de la symbolisation. Dans cette perspective, à l’appui d’une pratique d’observatrice écrivante et de la supervision de nombreux dispositifs de médiation picturale, l’auteure développe l’hypothèse d’une chaîne associative formelle, essentiellement constituée de signifiants formels (Anzieu) à l’œuvre dans le cadre des médiations thérapeutiques. Elle propose un tableau synthétique de « repères pour une évaluation clinique » de la mise en jeu de l’associativité formelle dans un dispositif de médiation picturale, référé à la psychothérapie psychanalytique.
Un effondrement de la confiance dans l'UE ?
Authors: Cautrès Bruno 
Published: January 2015

La période de « Grande Récession » depuis 2008 a entraîné une baisse de nombreux indicateurs de soutien des Européens à l’intégration européenne. Du point de vue de la confiance que les Européens font à l’Europe (une dimension importante de soutien diffus à l’UE), on peut même parler d’une véritable crise de confiance dans l’action de l’Union européenne constatée depuis 2008 dans les opinions des Européens. Dans certains pays (Grèce par exemple), on enregistre même un effondrement de cette confiance. L’analyse des données de deux vagues de l’Eurobaromètre, une vague au début de la crise et une autre en 2011, montre que si cet effondrement est bien avéré, et pas seulement sur les indicateurs de soutien diffus, les Européens n’impute pas la responsabilité de la crise à l’UE seulement. Ils perçoivent la crise et le rôle de l’Europe dans la crise à travers le prisme de l’expérience nationale qu’ils en ont. Par ailleurs, la crise de confiance dans l’UE n’entraîne pas ipso facto une grave crise de confiance dans l’euro : on ne constate pas d’effondrement comparable à celui que l’on observe en termes de confiance générale dans l’UE. Dans les pays membres de la zone euro les évolutions sont en légère baisse mais de manière qui n’est pas très significative ; ce sont dans les pays qui sont hors de la zone euro ou dans ceux qui sont candidats pour y entrer que la baisse du soutien à l’euro est la plus forte.
La bonne administration dans l'Union européenne
Authors: Streho Imola 
Published: January 2015

La confiance dans les institutions européennes est au plus bas alors que les institutions n’ont jamais été aussi transparentes, ouvertes, prêtes à dialoguer avec leurs « administrés européens ». Désormais le droit primaire de l’UE fait expressément référence à la bonne administration aussi bien dans les traités que dans la Charte des droits fondamentaux de l’UE (1). La place et les missions du Médiateur européen s’affirment également de façon constante dans le cadre institutionnel européen (2); un code européen de bonne conduite administrative formalise désormais les modalités des missions menées par les fonctionnaires européens (3) et une palette d’aide administrative a été mise en place au niveau de l’UE (4). Toutefois, le Parlement européen doit veiller au soutien constant des missions du Médiateur européen et aux recommandations formulées ci-dessous pour permettre des avancées concrètes en matière de bonne administration dans l’UE afin d’aboutir à terme à une confiance plus forte des citoyens « administrés » dans les institutions européennes.
Les mesures « anti-crise » et la transformation des compétences de l'Union en matière économique
Authors: Clément-Wilz Laure 
Published: January 2015

Les « mesures anti-crise » renforcent indéniablement l’implication de l’Union et de ses institutions, alors même que le domaine de compétence reste a priori le même : discipline budgétaire d’un côté, coordination des politiques économiques de l’autre. L’ensemble de ces instruments englobe à la fois les politiques budgétaires et économiques nationales ; ces mesures consistent à un contrôle accru opéré par les institutions de l’Union sur les États, notamment les États de la zone euro. Deux types de coordination ont ainsi fusionné, l’un fondé sur un dispositif souple de surveillance multilatérale entre États chapoté par le Conseil et l’autre axé sur une surveillance plus rigide de la part de la Commission. La surveillance des grandes orientations en matière économique par la Commission et le Conseil est plus précise que par le passé, notamment avec le nouveau mécanisme de sanction quasi-automatique des États de la zone euro. La conditionnalité de l’aide financière alourdit encore un peu plus la pression sur les États. Il convient de renforcer la démocratisation de l’ensemble par un renforcement du rôle du Parlement européen et des parlements nationaux et de donner une base juridique claire aux nouvelles missions des institutions de l’Union.
Au-delà de l'Union bancaire européenne
Authors: Pollin Jean-Paul 
Published: January 2015

Après avoir brièvement rappelé les avancées et surtout les limites du projet d’Union bancaire européenne, tel qu’il vient d’être accepté par les diverses parties prenantes, cet article cherche à décrire et à évaluer les réformes susceptibles de compléter le nouvel accord. Deux types de propositions sont évoqués : soit on renforce la régulation bancaire en engageant une réforme structurelle du secteur (une séparation des activités) et en définissant une politique macroprudentielle cohérente au niveau de l’Union, soit on s’efforce de réduire la part de l’intermédiation dans le financement de l’économie européenne en accroissant l’importance des marchés, au risque de heurter les fondements des systèmes économiques et sociaux d’Europe continentale.
