AbstractA sensitive tuning of dielectric properties under the application of magnetic field in Fe74.4Co21.6Si0.5B3.3Mn0.1C0.1/0.7Pb(Mg1/3Nb2/3)O3‐0.3PbTiO3 multiferroic composites is presented. We demonstrate large variations of the effective permittivity at resonance region under extremely low magnetic field of 4 Oe near room temperature. The tuning of the maximum dielectric permittivity at resonance and the corresponding frequency was systematically studied. We suggest that the magnetic dependence of the effective permittivity is consistent with a strain‐mediated magnetic‐elasto‐dielectric effect. Our results suggest a route towards future applications of the dielectric properties tuning effect in advanced devices.

Published: June 2012

AbstractBackground/PurposeSurgery can offer the only chance for a cure in patients with perihilar cholangiocarcinoma, and a growing number of elderly patients are undergoing resection. The purpose of this study was to evaluate the impact of patient age on surgery for perihilar cholangiocarcinoma.MethodsFrom 2001 to 2011, 431 consecutive patients underwent a potentially curative resection for perihilar cholangiocarcinoma at the Division of Surgical Oncology, Department of Surgery, Nagoya University Graduate School of Medicine. Perioperative and long‐term outcomes after surgery were compared between octogenarians (80 years and older, n = 21) and younger patients (less than 80 years old, n = 410).ResultsAll 21 octogenarians were healthy and deemed to be candidates for surgery; however, twenty (95 %) had one or more comorbidities. Nineteen (90 %) octogenarians underwent major hepatectomy with bile duct resection and the remaining two (10 %) underwent bile duct resection only, whereas almost all the (99 %) younger patients underwent hepatectomy (P = 0.021). Postoperative morbidity and mortality occurred in 57 and 5 % of the octogenarians, respectively. These rates were similar to those in the younger patients (P = 0.372 and P = 0.332, respectively). The overall 3‐ and 5‐year survival rates in the octogenarians were both 56.8 %, and 3 patients survived for more than 5 years. Their survival rate was similar to that of the younger patients (P = 0.348).ConclusionsSurgery for perihilar cholangiocarcinoma can be safely performed even in octogenarians, and careful patient selection can lead to acceptable morbidity, mortality, and long‐term survival. Octogenarian patients should not be precluded from surgical resection for perihilar cholangiocarcinoma.
Der Stellenwert der „array comparative genomic hybridization“ in der Pränataldiagnostik
Authors: Held K.R. , Kähler C. , Kerber S. , Auber B. 
Published: June 2012

Zusammenfassung
Die hochauflösende „array comparative genomic hybridization“ (Array-CGH) erkennt ohne eine vorhergehende Anzüchtung fetaler Zellen mit hoher Sicherheit Veränderungen in der Kopienzahl weit unterhalb des Auflösungsvermögens der konventionellen Chromosomenanalyse. Trotz dieser unstreitigen Vorteile wurde die Array-CGH bisher nur zögerlich in der Pränataldiagnostik eingesetzt. Dies ist auf die Befürchtung zurückzuführen, dass bei der Diagnostik genomische Kopienzahlveränderungen („copy number variations“, CNVs) mit unklarer Bedeutung detektiert werden können. Um Unsicherheiten zu minimieren, sollte die Array-CGH in der Pränataldiagnostik nicht als primäre („first tier“), sondern nur als ergänzende Diagnostik eingesetzt werden. Die Indikationen hierfür werden in der Arbeit definiert und begründet. Als Voraussetzung für die Durchführung sollten in jedem Labor klare Vorgaben bestehen hinsichtlich der Mindestgröße der Kopienzahlveränderungen, die bewertet, und der genomischen Regionen, die als klinisch relevant angesehen werden.
Geochemistry of silver in Permo-Triassic traps of the Siberian Platform
Authors: Medvedev A.Ya. , Al’mukhamedov A.I. 
Published: June 2012

Abstract
The first data on the silver content in volcanics of the West Siberian Plate are presented, and data on basalts of the Siberian Platform are supplemented. The silver contents in all studied rocks do not depend on the fractionation of initial melts and contamination of the host rocks and average 0.07–0.10 ppm. The high silver contents can be associated only with sulfide formation.
A geothermal method for detecting gas hydrates in the bottom sediments of water basins
Authors: Duchkov A.D. , Istomin V.E. , Sokolova L.S. 
Published: June 2012

Abstract
We formulate the fundamentals of the geothermal method for determining the hydrate saturation of bottom sediments. According to laboratory experiments (A.A. Trofimuk Institute of Petroleum Geology and Geophysics, A.V. Nikolaev Institute of Inorganic Chemistry), detecting gas hydrates in bottom sediments requires measurement of thermal conductivity at least twice at one bottom site, using a cylindrical probe with different heater power values. Changing the latter permits controlling gas hydrate stability and instability. A low-power probe does not destroy gas hydrates and permits measuring the true thermal conductivity of the sediments. Increasing heater power destroys gas hydrates near the probe and drastically increases effective thermal conductivity. Comparison between true and effective thermal conductivity clearly shows the presence of gas hydrates in the sample or their absence from it. A technique was proposed for the quantitative interpretation of changes in the temperature field of a cylindrical probe. It permits quite a precise determination of the mass of gas hydrate that decomposed in the layer surrounding the probe over a certain period. Also, it permits a rough estimation of the gas hydrate content of the sediments. Thermal conductivity can be measured in the field with submersible multichannel thermoprobes, which are commonly used for studying the heat flow through the bottom of water basins. Now it is important to perform field experiments, so that we gain the necessary experience with the geothermal method.
XXXII.—Extracts from Accounts of the Churchwardens of Minchinhampton, in the County of Gloucester, with Observations thereon. By John Bruce, Esq. Treas. S.A.
Authors: Bruce John 
Published: June 2012

An opportunity having been afforded me of inspecting a collection of old churchwardens' accounts, I have made some extracts from them, which I beg leave to submit to this Society.The importance of this class of historical evidences has been long universally admitted. Illustrations of manners and customs, information as to prices and comparative values, and interesting facts in history, topography, and biography have been derived from these humble records. The present accounts differ in some respects from those which have been already published, and, although certainly not to be compared in point of interest with one or two of the most important, they will not, I think, be deemed unworthy of consideration.

I am just recovering from an attack of illness, or I would certainly have sooner acknowledged your kind attention in sending me six copies of your report on my Collection from Sacrificios, for which I beg to return you my best thanks.Your observations on the whole coincide with my own preconceived opinions, with the exception of what I consider one of its most important points; I allude to the antiquity of the collection, which you consider to have been the work of the Aztecks, or comparatively modern Mexicans, of the period of the Conquest by Cortez. You will I hope excuse me if I differ from you in this respect, and that you will permit me to make the following observations thereon. I premise by stating, that by far the greater portion, and indeed the best of the specimens, were found at a depth of from ten to fourteen feet in rich dark soil; my objections, therefore, to your view of the case is principally founded on the geology of the island of Sacrificios.
Arabidopsis NRT1.5 Is Another Essential Component in the Regulation of Nitrate Reallocation and Stress Tolerance
Authors: Chen Chun-Zhu , Lv Xin-Fang , Li Jian-Yong , Yi Hong-Ying , Gong Ji-Ming 
Published: June 2012

AbstractNitrate reallocation to plant roots occurs frequently under adverse conditions and was recently characterized to be actively regulated by Nitrate Transporter1.8 (NRT1.8) in Arabidopsis (Arabidopsis thaliana) and implicated as a common response to stresses. However, the underlying mechanisms remain largely to be determined. In this study, characterization of NRT1.5, a xylem nitrate-loading transporter, showed that the mRNA level of NRT1.5 is down-regulated by salt, drought, and cadmium treatments. Functional disruption of NRT1.5 enhanced tolerance to salt, drought, and cadmium stresses. Further analyses showed that nitrate, as well as Na+ and Cd2+ levels, were significantly increased in nrt1.5 roots. Important genes including Na +/H + exchanger1, Salt overly sensitive1, Pyrroline-5-carboxylate synthase1, Responsive to desiccation29A, Phytochelatin synthase1, and NRT1.8 in stress response pathways are steadily up-regulated in nrt1.5 mutant plants. Interestingly, altered accumulation of metabolites, including proline and malondialdehyde, was also observed in nrt1.5 plants. These data suggest that NRT1.5 is involved in nitrate allocation to roots and the consequent tolerance to several stresses, in a mechanism probably shared with NRT1.8.

Published: June 2012

PurposeThe purpose of this paper is to describe the fisheries governance system in the European Union (EU) and review fishers’ participation in the decision‐making process in the EU.Design/methodology/approachThe study was based on a variety of sources, such as review of the literature, including scientific articles and reports, and data collected by the Coastal Transects Analysis Model (CTAM) online decision support tool.FindingsThe review reveals major improvements in involving fishers in the decision‐making process in Europe, but participation and empowerment are still generally lacking.Social implicationsThe lack of fisher participation in the decision‐making process leads to limited acceptance of management measures which in turn results in management objectives not being met, with negative effects on environmental, economic and social sustainability.Originality/valueThe paper provides a review of participation in the EU decision‐making process. The results could give management bodies an insight into the failures of participation and point to possible ways forward.
Sustainable coastal zones? A matter of “sense and sensibility”
Authors: Rosário Bastos Maria , Alveirinho Dias João , Dias Ana Cristina , Dias Pereira Silvia , Vieira de Oliveira Nanci , Antonieta Rodrigues Maria 
Published: June 2012

PurposeThe purpose of this paper is to perform a comparative analysis between Aveiro's Lagoon (Portugal) and Sepetiba Bay (Brazil), in order to understand the similarities and differences between these two coastal zones, in terms of human occupation.Design/methodology/approachThis paper is supported by works (papers and scientific projects being developed) produced in Portugal and Brazil, by researchers from different areas of expertise.FindingsThese two coastal zones have a similar geomorphologic evolution, due to the fact that both appeared because of a sandy spit, which started to grow and separated these areas from the sea, converting them into sheltered coasts. It was because they are protected that these two study cases early became targets for human occupation. The anthropic impacts in the systems were sustainable until the middle of the twentieth century. Since then, however, the economic development options, based first in industry and second in tourism exploration, have compromised the natural healthy balance.Practical implicationsThis paper could be a contribution to a scientific support for political decisions on the coastal zone management (namely in these studied areas).Social implicationsThe paper provides and increases the knowledge of the coastal zones’ evolution and occupation – from a multidisciplinary perspective – produced and made available to scientists, local politicians, students and local populations.Originality/valueThe paper provides a truly interdisciplinary approach, which allows a better understanding of the evolution of these two systems, discussing the causes and consequences of human activities in both coastal areas.
Promoting sustainable aquaculture
Authors: Fernandes Borges Pena Seixas Sónia Isabel , Bostock John , Eleftheriou Margaret 
Published: June 2012

PurposeThe purpose of this paper is to review a number of recent initiatives to promote sustainable aquaculture development through improvements to education and training capacity, and innovations in the use of eLearning.Design/methodology/approachThe authors share their experience in these initiatives and demonstrate how e‐learning has been developed in specific cases to better serve the needs of the aquaculture sector, while addressing the pedagogical issues of distance learning and finding the best use of new internet‐based technologies.FindingsThese examples show how to respond to the needs of adult learners who may have a substantially different learner profile to typical campus students and have a more diverse range of needs and background knowledge. Greater focus is needed on defining, enhancing and accrediting knowledge and skills acquired informally and “on the job”, so as to develop more effective formal education interventions.Practical implicationsAdults engaging with job‐related education are not empty vessels requiring to be filled with the correct mix of knowledge and skills by teachers who know all the answers. They are active learners seeking a supportive and enabling structure involving access to appropriate resources, engagement with fellow learners and more expert practitioners, and appropriate challenges and rewards to maximise effort and achievement.Originality/valueThe paper shows that there is substantial social benefit in promoting an innovative and sustainable aquaculture industry that contributes positively to food security and human health. Continued Professional Development involving eLearning and other innovative approaches can make an important contribution throughout the sector.
A comparative evaluation of women's perceptions and importance of sustainability in fish consumption
Authors: Pinto de Moura Ana , Cunha Luís M. , Castro‐Cunha M. , Costa Lima Rui 
Published: June 2012

PurposeThe purpose of this paper is to explore women's perceptions about the benefits and risks of fish consumption, while exploring differences on their views about wild and farmed fish, considering light fish consumers.Design/methodology/approachThe methodology adopted is exploratory, using focus group technique, segregating women by education level (higher education versus lower education). A focus group guide was designed, taking into account the following dimensions: attitudes towards fish consumption and perceptions towards farmed fish relative to wild fish, also considering risk perceptions related to farmed versus wild fish.FindingsThis study has shown that fish consumers enjoy the taste of fish and they are strongly convinced that eating fish is healthy. The main reason for their low fish consumption is related to perceive lacking of convenience. Women with higher education levels expressed additional knowledge considering different aquaculture systems and women with lower education levels were convinced that both wild and farmed fish offer benefits and present disadvantages.Originality/valueThe paper shows that attitudes of light fish users are partially similar to heavy fish users considering farmed fish production, with the search for convenience being driven by either perceived lack of time or perceived lack of cookery skills to prepare fish‐based meals.
