Authors: Fér Miroslav , Leue Martin , Kodešová Radka , Gerke Horst H. , Ellerbrock Ruth H. 
Published: May 2016

Abstract
The organo-mineral coatings of soil aggregates, cracks, and biopores control sorption and macropore-matrix exchange during preferential flow, in particular in the clay-illuvial Bt-horizon of Luvisols. The soil organic matter (SOM) composition has been hypothesized to explain temporal changes in the hydraulic properties of aggregate surfaces. The objective of this research was to find relations between the temporal change in wettability, in terms of droplet infiltration dynamics, and the SOM composition of coated and uncoated aggregate surfaces. We used 20 to 40 mm sized soil aggregates from the Bt2 horizon of a Haplic Luvisol from loess that were (i) coated, (ii) not coated (both intact), and (iii) aggregates from which coatings were removed (cut). The SOM composition of the aggregate surfaces was characterized by infrared spectroscopy in the diffuse reflection mode (DRIFT). A potential wettability index (PWI) was calculated from the ratio of hydrophobic and hydrophilic functional groups in SOM. The water drop penetration times (WDPT) and contact angles (CA) during droplet infiltration experiments were determined on dry and moist aggregate samples of the three types. The decrease in the CA with time was described using the power function (CA(t) = at−b
). For dry aggregates, the WDPT values were larger for coated as compared to uncoated regions on the aggregate surfaces, and increased with increasing PWI value (R
2 = 0.75). The a parameter was significantly related to the WDPT (R
2 = 0.84) and to the PWI (R
2 = 0.64). The relations between the b parameter and the WDPT (R
2 = 0.61) and the PWI (R
2 = 0.53) were also significant. The WDPT values of wet soil aggregates were higher than those of dry aggregates due to high water contents, which limited the droplet infiltration potential. At the wet aggregate surfaces, the WDPT values increased with the PWI of the SOM (R
2 = 0.64). In contrast to dry samples, no significant relationships were found between parameters a or b of CA(t) and WDPT or PWI for wet aggregate surfaces. The results suggest that the effect of the SOM composition of coatings on surface wettability decreases with increasing soil moisture. In addition to the dominant impact of SOM, the wettability of aggregate surfaces could be affected by different mineralogical compositions of clay in coatings and interiors of aggregates. Particularly, wettability of coatings could be decreased by illite which was the dominant clay type in coatings. However, the influence of different clay mineral fractions on surface wettability was not due to small number of measurements (2 and 1 samples from coatings and interiors, respectively) quantified.

AbstractIn the present study, trends and variations in climatic variables (i.e. rainfall, wet day frequency, surface temperature, diurnal temperature, cloud cover, and reference and potential evapotranspiration) were analyzed on seasonal (monsoon and non-monsoon) and annual time scales for the Ajmer District of Rajasthan, India. This was done using non-parametric statistical techniques, i.e. the Mann–Kendall (MK) and Modified Mann–Kendall (MMK) tests, over a period of 100 years. The MK test with prewhitening (MK–PW) of climatic series was also applied to climatic variables and the results were compared to those obtained through the MK and MMK tests in order to assess the performance of trend detection methods. The Pettitt–Mann–Whitney (PMW) test was applied to detect the temporal shift in climatic series. The trend analysis revealed that annual and seasonal rainfall did not show any statistically significant trend at a 10% significant level. A noticeable trend increase was found in wet day frequency, surface temperature and reference evapotranspiration (ET) during the non-monsoon season from the three non-parametric statistical tests at a 10% significance level. A statistically significant decrease in maximum temperature was found during the non-monsoon season by the MK–PW test alone. This analysis of several climatic variables at the district scale is helpful for the planning and management of water resources and the development of adaptation strategies in adverse climatic conditions.

Published: May 2016

Abstract
The paper presents results of research aimed at determining the corrosive properties of steel with cathode metal coating in selected corrosive environments. The corrosion properties of the tin coated steel were evaluated using electrochemical impedance spectroscopy and potentiodynamic tests. For realised measurements, distilled water, 0.5 mol dm−3 NaCl solution, 0.1 mol dm−3 NaCl solution and SARS, which simulates acid rain were used as corrosive solutions. Both corrosion methods are suitable for diagnosing corrosion properties of steel with metal coatings.
Evaluation of corrosion attack of chimney liners

Published: May 2016

Abstract
The case study of chimney liner corrosion addresses three specific cases of damage of chimney systems from of stainless steels. These systems were used for flue of gas arising from the combustion of brown coal in small automatic boilers, which are used for heating. Detailed analyzes implied that the cause of devastating corrosion of the steel AISI 316 and 304 steel (CSN 17349, 17241) was particularly high content of halides (chlorides and fluorides), which caused a severe pitting corrosion, which led up to the perforation of the liner material. Simultaneous reduction of the thickness of the used sheets was due to by the general corrosion, which was caused by the sulfur in the solid fuel. The condensation then led to acid environment and therefore the corrosion below the dew point of the sulfuric acid has occurred. All is documented by metallographic analysis and microanalysis of the corrosion products.
Review of recent EU funded research projects from
the perspective of urban sound planning: do the
results cope with the needs of Europe’s noise
policy?
Authors: Alves Sonia , Scheuren Joachim , Altreuther Beate 
Published: May 2016

Abstract
Noise pollution is one of the major environmental
problems affecting European citizens in urban areas.
Although the Environmental Noise Directive is in force
since 2002, there is still a gap between defined objectives
and outcomes. The EU Seventh Environment Action Programme
attempts to achieve the reduction of noise pollution
by means of more effective European noise policies.
This must be coupled with providing assistance to local
administrations on dealing with existing noise problems,
for example through Urban Sound Planners.
The aim of this paper is to present the results of a systematic
review of European projects addressing urban sound
planning topics and furthermore an overview of the most
relevant research results that can be applied by practitioners.
In order to understand the European funding strategy,
the most valued research topics (number of projects
and funding support) are assessed. A key finding of this
review is the disagreement between air traffic noise research
funding and its importance on overall noise exposure.
Another finding is that the scientific knowledge for
urban sound planning exists but it requires adequately
dissemination of results, among the policy makers and local
authorities, who are usually responsible for policy implementation.
Narrative Writing in Digital Formats: Interpreting the Impact of Audience
Authors: Lawrence Joshua Fahey , Niiya Melissa , Warschauer March 
Published: May 2016

Abstract
Digital writing has enabled students to write for a variety of authentic audiences, both in and out of the classroom. As they consider audience, students shoulder a cognitive burden that they must juggle in addition to the task of composition. At the same time, writing provides students with opportunities to craft and express their identities. The ways that identity formation and cognitive load intersect may be particularly complex in digital, online writing environments, as students gain the ability to share and receive feedback from global and local audiences. In this counterbalanced experimental study, 86 seventh- and eighth-grade students responded to two narrative prompts. One prompt was written for the teacher and the other was written for the teacher and peers in an online forum. We examined student writing fluency, mechanical errors, academic word use, and setting. Students were found to be more likely to set narratives in private settings when writing for an audience that included peers. We discuss this finding from cognitive and sociocultural perspectives and how it might inform networked communication research.
Superdense Coding Interleaved with Forward Error Correction
Authors: Sadlier Ronald J. , Humble Travis S. 
Published: May 2016

AbstractSuperdense coding promises increased classical capacity and communication security but this advantage may be undermined by noise in the quantum channel. We present a numerical study of how forward error correction (FEC) applied to the encoded classical message can be used to mitigate against quantum channel noise. By studying the bit error rate under different FEC codes, we identify the unique role that burst errors play in superdense coding, and we show how these can be mitigated against by interleaving the FEC codewords prior to transmission. We conclude that classical FEC with interleaving is a useful method to improve the performance in near-term demonstrations of superdense coding.
Phase estimation with squeezed single photons
Authors: Olivares Stefano , Popovic Maria , Paris Matteo G. A. 
Published: May 2016

AbstractWe address the performance of an interferometric setup in which a squeezed single photon interferes at a beam splitter with a coherent state. Our analysis in based on both the quantum Fisher information and the sensitivity when a Mach-Zehnder setup is considered and the difference photocurrent is detected at the output. We compare our results with those obtained feeding the interferometer with a squeezed vacuum (with the same squeezing parameter of the squeezed single photon) and a coherent state in order to have the same total number of photons circulating in the interferometer. We find that for fixed squeezing parameter and total number of photons there is a threshold of the coherent amplitude interfering with the squeezed single photon above which the squeezed single photons outperform the performance of squeezed vacuum (showing the highest quantum Fisher information). When the difference photocurrent measurement is considered, we can always find a threshold of the squeezing parameter (given the total number of photons and the coherent amplitude) above which squeezed single photons can be exploited to reach a better sensitivity with respect to the use of squeezed vacuum states also in the presence of non unit quantum efficiency.
The semiotics of migrants’ food: Between codes and experience
Authors: Greco Sara 
Published: May 2016

AbstractThis paper sets out to analyze cultural semiotics of migrants’ food and culinary practices. Moving from the perspective of the Tartu school of semiotics, which views culture both as a grammar (a set of codes) and as a set of texts, food can be characterized as a specific cultural element where grammar and text (code and experience) are woven together. International migrants live one or more ruptures and changes in their status quo due to their adaptation to the receiving country, which puts their cultural habits into questions. In this framework, even “normal” and well-established culinary practices might need to change. In this relation, I claim that it is on the basis of migrants’ new experience abroad that it is possible to change culinary grammars. In order to move beyond a descriptive account of change, and understand the reasons why migrants construct a new semiotics of food, this paper also integrates elements from argumentation theory in order to analyze the reasons given by migrants to explain the changes they are making. The analysis proposed here is based on a corpus of interviews to migrating mothers of different origins, all living in the greater London area.
The McKittrick–Wheelock syndrome: a rare cause of curable diabetes
Authors: Challis Benjamin G , Lim Chung Thong , Cluroe Alison , Cameron Ewen , O’Rahilly Stephen 
Published: May 2016

Summary
McKittrick–Wheelock syndrome (MWS) is a rare consequence of severe dehydration and electrolyte depletion due to mucinous diarrhoea secondary to a rectosigmoid villous adenoma. Reported cases of MWS commonly describe hypersecretion of mucinous diarrhoea in association with dehydration, hypokalaemia, hyponatraemia, hypochloraemia and pre-renal azotemia. Hyperglycaemia and diabetes are rarely reported manifestations of MWS. Herein we describe the case of a 59-year-old woman who presented with new-onset diabetes and severe electrolyte derangement due to a giant rectal villous adenoma. Subsequent endoscopic resection of the tumour cured her diabetes and normalised electrolytes. This case describes a rare cause of ‘curable diabetes’ and indicates hyperaldosteronism and/or whole-body potassium stores as important regulators of insulin secretion and glucose homeostasis.

Learning points

McKittrick–Wheelock syndrome (MWS) is typically characterised by the triad of pre-renal failure, electrolyte derangement and chronic diarrhoea resulting from a secretory colonic neoplasm.
Hyperglycaemia and new-onset diabetes are rare clinical manifestations of MWS.
Hyperaldosteronism and/or hypokalaemia may worsen glucose tolerance in MWS.
Aggressive replacement of fluid and electrolytes is the mainstay of acute management, with definitive treatment and complete reversal of the metabolic abnormalities being achieved by endoscopic or surgical resection of the neoplasm.
Fred Ho’s Wicked Theory and Naked Practice
Authors: Anthony III David H. 
Published: May 2016

To speak of someone as unparalleled often seems trite; in Fred Ho’s case, it seems mandatory. A composer, musician, performance artist, and scholar, he really lived a life beyond categorization. In 2009, with the collaboration of Diane C. Fujino, the University of Minnesota Press published a retrospective anthology of his writings titled Wicked Theory, Naked Practice. Sadly, that volume is now also a memorial: a self-written festschrift. On April 12, 2014, Fred Ho succumbed to cancer, leaving behind an astonishingly innovative body of work. Fred Wei-Han Houn, or Hóu Wéihàn, later more popularly known as Fred Ho, was extraordinary. A virtuosic talent, he was a renaissance person without being limited by the masculinist modifier “man.” Wicked Theory, Wicked Practice offers a cross-section of Ho’s passionate written work over a decade. This collection is divided into four parts: 1) “The Movement and The Self,” 2) “Music Aesthetics and Artistic Production,” 3) “Asian American Pacific Cultural Theory and Criticism,” and 4) “Wicked Theory, Naked Practice.” However, the book really may be read in any order. In fact, tackling it out of order or choosing a random article might be in keeping with the improvisatory quality of much of Ho’s work. It is evocative of a quotation attributed to Cecil Taylor to the effect that “If a man plays for a certain amount of time—scales, licks, what have you—eventually a kind of order asserts itself.”

Published: May 2016

ZusammenfassungZiel der Studie war, die diagnostische Aussagekraft der mittels Niederfeld- Magnetresonanztomographie (MRT) erhobenen Befunde bei septischen Erkrankungen im Hufbereich nach durchdringenden Verletzungen (Nageltritt) zu überprüfen. Material und Methoden: Bei 10 Pferden mit Verletzungen im Hufbereich wurden die MRT-Befunde mittels klinischer, chirurgischer, röntgenologischer, sonographischer und computertomographischer Befunde und/oder postmortaler histologischer Untersuchung validiert. Ergebnisse: Am genauesten ließ sich eine Beteiligung des Strahlbeins nachweisen, die am besten in der fettunterdrückten Sequenz (Short-Tau-Inversion-Recovery-Sequenz, STIR) ermittelt wurde. Defekte der tiefen Beugesehne waren ausgezeichnet nachweisbar, aber unspezifischer als Veränderungen des Strahlbeins. Sie ließen sich am besten in transversalen T2-gewichteten Fast-Spin- Echo-Sequenzen (T2w FSE) nachvollziehen. Der Stichkanal war in sämtlichen Fällen in allen Ebenen erkennbar. Auch hier erwies sich die T2w FSE als gut geeignet. Am wenigsten deutlich konnte die septische Bursitis nachvollzogen werden. Eine Erkrankung der Bursa war am besten in der sagittalen Ebene erkennbar. Schlussfolgerung und klinische Relevanz: Die MRT-Diagnostik von Erkrankungen im Hufbereich nach Verletzung durch Fremdkörper (vor allem Nageltritt) stellt eine zuverlässige Untersuchungsmethode zur Absicherung der Diagnose dar. Dabei eignet sich eine transversale T2w FSE am besten zum Nachweis eines Stichkanals und Sehnendefekts. Für die Diagnostik der Bursitis sind der Stichkanalverlauf und sekundäre Reaktionen des Strahlbeins ausschlaggebend. Fettunterdrückte Sequenzen können eine Knochenbeteiligung gut nachweisen, wenn der Stichkanal nicht direkt bis auf den Knochen zu verfolgen ist. Die beschriebenen Fälle verdeutlichen, dass bei durchdringenden Verletzungen im Hufbereich eine MRT-Untersuchung angezeigt sein kann, wenn die Beteiligung von Strukturen vermutet wird, die eine schlechte Prognose bedingen. Nur die MRT erlaubt intravital eine Beurteilung der verschiedenen Strukturen innerhalb der Hornkapsel. Diese Information wie derum ist essenziell bei der Entscheidungsfindung für eine gezielte Therapie bzw. einer Vermeidung unnötiger Behandlungen.
