Published: September 2017

BACKGROUND

The heating of a green smoothie during an innovative semi‐continuous microwave treatment (MW; 9 kW for 15 s) was modelled. Thermal and dielectric properties of the samples were previously determined. Furthermore, the heating effect on the main chemopreventive compounds of the smoothie and during its subsequent storage up to 30 days at 5 or 15 °C were studied. Such results were compared to conventional pasteurisation (CP; 90 °C for 45 s) while unheated fresh blended samples were used as the control.

RESULTS

A procedure was developed to predict the temperature distribution in samples inside the MW oven with the help of numerical tools. MW‐treated samples showed the highest sulforaphane formation after 20 days, regardless of the storage temperature, while its content was two‐fold reduced in CP samples. Storage of the smoothie at 5 °C is crucial for maximising the levels of the bioactive compound S‐methyl cysteine sulfoxide.

CONCLUSION

The proposed MW treatment can be used by the food industry to obtain an excellent homogeneous heating of a green smoothie product retaining high levels of bioactive compounds during subsequent retail/domestic storage up to 1 month at 5 °C. © 2017 Society of Chemical Industry

Published: September 2017

Advanced donor age has been identified as a risk factor when combined with donor warm ischemia time (WIT), eg, in donation after circulatory death (DCD). In several countries, DCD livers older than 60 years are not considered suitable due to concerns related to poor graft function and development of ischemic cholangiopathy. In this study, we evaluate outcomes after DCD liver transplantation using grafts from donors older than 60 years. We analyzed outcomes after DCD liver transplantation (n = 315), comparing donors > 60 years (n = 93) and donors ≤ 60 years (n = 222) from our center between 2005 and 2015. End points included graft function and complications and patient and graft survival. Multivariate risk analysis was performed to define further key factors that predicted inferior outcome. Donor age at the cutoff 60 years failed to stratify patient and graft survival. The rate of vascular, biliary, and overall complications was comparably low in both cohorts, and the median comprehensive complication index was 42.7 points, independent from the donor age. Second, donor body mass index (BMI) above a threshold of 25 kg/m2 significantly impacted on graft and patient survival at any donor age, whereas donor WIT and cold ischemia times were not predictive for graft loss. In conclusion, older DCD donors can be successfully used for liver transplantation with good longterm outcomes when further risk factors are limited. Additional risk is transmitted by an increased donor BMI regardless of donor age. Liver Transplantation 24 352–362 2018 AASLD.
Gadoxetic acid disodium–enhanced magnetic resonance imaging outperformed multidetector computed tomography in diagnosing small hepatocellular carcinoma: A meta‐analysis

Published: September 2017

Early detection of small hepatocellular carcinoma (HCC) lesions can improve longterm patient survival. A systematic review and meta‐analysis of the diagnostic performance of gadoxetic acid disodium (Gd‐EOB‐DTPA)–enhanced magnetic resonance imaging (MRI) and multidetector computed tomography (MDCT) was performed in diagnosing small HCCs measuring up to 2 cm (≤2 cm). Two investigators searched multiple databases for studies in which the performances of either Gd‐EOB‐DTPA–enhanced MRI or MDCT were reported with sufficient data to construct 2 × 2 contingency tables for diagnosing HCCs up to 2 cm on a per‐lesion or per‐patient level. Diagnostic performances were quantitatively pooled by a bivariate random‐effect model with further meta‐regression and subgroup analyses. A total of 27 studies (14 on Gd‐EOB‐DTPA–enhanced MRI, 9 on MDCT, and 4 on both) were included, enrolling a total of 1735 patients on Gd‐EOB‐DTPA–enhanced MRI and 1781 patients on MDCT. Gd‐EOB‐DTPA–enhanced MRI demonstrated significantly higher overall sensitivity than did MDCT (0.96 versus 0.65; P < 0.01), without substantial loss of specificity (0.94 versus 0.98; P > 0.05). Area under the summary receiver operating characteristic curve was 0.97 with Gd‐EOB‐DTPA–enhanced MRI and 0.85 with MDCT. Regarding Gd‐EOB‐DTPA–enhanced MRI, sensitivity was significantly higher for studies from non‐Asian countries than Asian countries (0.96 versus 0.93; P < 0.01), for retrospective studies than prospective studies (0.95 versus 0.91; P < 0.01), and for those with Gd‐EOB‐DTPA injection rate ≥ 1.5 mL/s than that of <1.5 mL/s (0.97 versus 0.90; P < 0.01). In conclusion, Gd‐EOB‐DTPA–enhanced MRI demonstrated higher sensitivity and overall diagnostic accuracy than MDCT, and thus should be the preferred imaging modality for diagnosing small HCCs measuring up to 2 cm.

Cleanest cities in India 2017: Indore's meteoric rise to no. 1 spot
Authors: Nidugala Ganesh Kumar , Pant Abhay
Published: September 2017

The Indian government initiated “Cleanliness Survey” of Indian cities in 2014 to promote clean cities. Under this initiative cities are ranked based on certain parameters. Indore city was ranked poorly at 149 in 2014 survey. The newly appointed Indore Municipal Corporation commissioner was confronted with the task of turning around the situation. The task was huge, required meticulous planning and flawless execution to achieve the mission. To the surprise of many including the citizens of the city, Indore achieved no. 1 rank in the cleanliness survey, 2017. We discuss the challenges faced by the Indore Municipal Corporation authorities, the response to these challenges, and critical success factors and make recommendations to sustain the top rank. Indore's success was a result of several activities that constitute a part of public affairs. The study identifies change management, corporate social responsibility, employee communications, external communication, and stakeholder management as important organizational activities that contributed in Indore's success. Learning from the study may be useful for urban local bodies and governments in other developing countries.
How does the exosite of rhomboid protease affect substrate processing and inhibition?
Authors: Shokhen Michael , Albeck Amnon
Published: September 2017

Rhomboid proteases constitute a family of intramembrane serine proteases ubiquitous in all forms of life. They differ in many aspects from their soluble counterparts. We applied molecular dynamics (MD) computational approach to address several challenging issues regarding their catalytic mechanism: How does the exosite of GlpG rhomboid protease control the kinetics efficiency of substrate hydrolysis? What is the mechanism of inhibition by the non‐competitive peptidyl aldehyde inhibitors bound to the GlpG rhomboid active site (AS)? What is the underlying mechanism that explains the hypothesis that GlpG rhomboid protease is not adopted for the hydrolysis of short peptides that do not contain a transmembrane domain (TMD)? Two fundamental features of rhomboid catalysis, the enzyme recognition and discrimination of substrates by TMD interactions in the exosite, and the concerted mechanism of non‐covalent pre‐catalytic complex to covalent tetrahedral complex (TC) conversion, provide answers to these mechanistic questions.
The Leaf as a Sustainable and Renewable System
Authors: Krupanidhi Srirama , Madhan Sai N. , Leung Homan , Kineman John J.
Published: September 2017

Leaves play a critical role in the Earth's biosphere, regulating weather, renewing mineral nutrients and maintaining biotic processes to support both flora and fauna. Leaves also form an important resource for consumers. Together, plant hosts and consumers represent complex adaptive selection. We used systems dynamic and holon models to understand the ability of the leaf to meet both host plant and host consumer criteria resulting in socio‐ecological system sustainability. We first identified dynamic cycles facilitated by the leaf as a component of both plant and consumer systems. Each of the variables in these loops serves a critical role in the production and function of the leaf, recycling energy and matter through plant and consumer systems. Control feedback balances the system, optimizing opposing selective forces to meet criteria for viability of host plants and usability by consumers, which return benefits through various services. We then examine the organization of the leaf host system, revealing mutually closed sub‐systems corresponding to a definition of ‘component life’. We thus show the leaf host relation to be a theoretically ‘whole’ system having positive, sustainable impacts on biomass, food, energy, etc. These results may inform more general sustainability assessments by offering a mathematical definition of sustainability as emergent, cyclical organization in ecosystems.

We Count, California! A Statewide Capacity‐Building Effort to Improve Youth Inclusion in California's Point‐in‐Time Homeless Counts
Authors: Lin Jessica S. , Petry Laura , Hyatt Shahera , Auerswald Colette
Published: September 2017

As is the case across the nation, youth in California experiencing homelessness are often undercounted and overlooked. We Count, California!, a collaboration between the California Homeless Youth Project and the University of California, Berkeley School of Public Health was formed to support California communities in better counting and describing their homeless youth in the 2015 Point‐in‐Time (PIT) count. Project activities included a series of trainings across the state, provision of seed grants to communities conducting youth‐specific count activities, and provision of one‐on‐one technical assistance to two nonurban, under‐resourced pilot sites. Despite considerable increases in the energy, commitment, and funding dedicated to youth counts across California, results of the 2015 PIT count were mixed. In this article, we discuss promising practices, successes, and continuing challenges for youth‐inclusive PIT counts. We conclude with recommendations for local initiatives and policy‐level interventions for developing a more accurate and inclusive picture of youth homelessness in California and nationwide.
Using a Gender‐Responsive Approach to Generate Policy, Systems, and Environmental Changes to Improve Women's Health
Authors: Burke Jodi , Lombard Wendy , Lachance Laurie , Kelly Patrick , Wilken Margaret , Waddell Sandra
Published: September 2017

Community coalitions have proven to be an effective mechanism for identifying and addressing social determinants of health. This project mobilized the Inkster Partnership for a Healthier Community (IPHC) coalition, bringing together diverse organizations, and community residents in Inkster, MI to collaboratively develop a strategic plan to address health inequities revealed in a community health needs assessment (CHNA). The coalition designed a multi‐faceted, gender‐responsive approach designed to increase social connectedness as a means to improve health and foster well‐being among women in the community. The approach included three core strategies: (i) providing health literacy mentoring, (ii) using community health workers (CHWs) and lay health educators to increase opportunities for access to and use of community health resources and self‐management programs, and (iii) publicizing targeted health messages intended to positively influence gender norms related to women's health. Emphasis was also placed on instituting policy systems and environmental (PSE) changes to promote sustainable community health improvements. Initial implementation outcomes indicate that a gender‐responsive approach to community health improvement initiatives is a promising model for how coalitions can purposefully adapt and evolve to incorporate gender‐based considerations into programmatic and PSE change efforts that equitably benefit all residents.
Overly determined agents prevent consensus in a generalized Deffuant model on ℤ with dispersed opinions
Authors: Hirscher Timo
Published: September 2017

During the last decades, quite a number of interacting particle systems have been introduced and studied in the crossover area of mathematics and statistical physics. Some of these can be seen as simplistic models for opinion formation processes in groups of interacting people. In the model introduced by Deffuantet al.(2000), agents that are neighbors on a given network graph, randomly meet in pairs and approach a compromise if their current opinions do not differ by more than a given threshold value θ. We consider the two-sided infinite path ℤ as the underlying graph and extend existing models to a setting in which opinions are given by probability distributions. Similar to what has been shown for finite-dimensional opinions, we observe a dichotomy in the long-term behavior of the model, but only if the initial narrow mindedness of the agents is restricted.
Dirichlet approximation of equilibrium distributions in Cannings models with mutation
Authors: Gan Han L. , Röllin Adrian , Ross Nathan
Published: September 2017

Consider a haploid population of fixed finite size with a finite number of allele types and having Cannings exchangeable genealogy with neutral mutation. The stationary distribution of the Markov chain of allele counts in each generation is an important quantity in population genetics but has no tractable description in general. We provide upper bounds on the distributional distance between the Dirichlet distribution and this finite-population stationary distribution for the Wright–Fisher genealogy with general mutation structure and the Cannings exchangeable genealogy with parent independent mutation structure. In the first case, the bound is small if the population is large and the mutations do not depend too much on parent type; 'too much' is naturally quantified by our bound. In the second case, the bound is small if the population is large and the chance of three-mergers in the Cannings genealogy is small relative to the chance of two-mergers; this is the same condition to ensure convergence of the genealogy to Kingman's coalescent. These results follow from a new development of Stein's method for the Dirichlet distribution based on Barbour's generator approach and a probabilistic description of the semigroup of the Wright–Fisher diffusion due to Griffiths and Li (1983) and Tavaré (1984).
SQUARE WITH BUILT-IN DIAMOND-PLUS
Authors: RINOT ASSAF , SCHINDLER RALF
Published: September 2017

We formulate combinatorial principles that combine the square principle with various strong forms of the diamond principle, and prove that the strongest amongst them holds in L for every infinite cardinal.

As an application, we prove that the following two hold in L:

1.

For every infinite regular cardinal λ, there exists a special λ+-Aronszajn tree whose projection is almost Souslin;

2.

For every infinite cardinal λ, there exists a respecting λ+-Kurepa tree; Roughly speaking, this means that this λ+-Kurepa tree looks very much like the λ+-Souslin trees that Jensen constructed in L.
TAMENESS AND FRAMES REVISITED
Authors: BONEY WILL , VASEY SEBASTIEN
Published: September 2017

We study the problem of extending an abstract independence notion for types of singletons (what Shelah calls a good frame) to longer types. Working in the framework of tame abstract elementary classes, we show that good frames can always be extended to types of independent sequences. As an application, we show that tameness and a good frame imply Shelah’s notion of dimension is well-behaved, complementing previous work of Jarden and Sitton. We also improve a result of the first author on extending a frame to larger models.
DECIDABILITY AND CLASSIFICATION OF THE THEORY OF INTEGERS WITH PRIMES

We show that under Dickson’s conjecture about the distribution of primes in the natural numbers, the theory Th (ℤ , +, 1, 0, Pr) where Pr is a predicate for the prime numbers and their negations is decidable, unstable, and supersimple. This is in contrast with Th (ℤ , +, 0, Pr, <) which is known to be undecidable by the works of Jockusch, Bateman, and Woods.
Jerusalem: Archaeologists Versus Residents?
Authors: Galor Katharina
Published: September 2017

Very few cities are defined as much by their antiquities as Jerusalem: religiously, culturally, politically, and economically. Erasing the Old City, or at least part of it, as suggested variously by Theodor Herzl and David Ben-Gurion, would have been an act difficult to reverse. The ruins of the past are now recognized and protected as the city's most distinct physical and visual attribute, in which past and present landscapes mingle to project the deceitful image of harmony. That said, this paper is not concerned with the usual questions of how certain monuments or artifacts inform us about past accomplishments or lost cultures. It in fact distances itself from the material and visual dimensions of Jerusalem's antiquities and addresses instead the human aspects exclusively, questioning the interaction between those who explore Jerusalem's antiquities and those who dwell amongst the surviving remnants. This polarized encounter between archaeologists and residents has defined most of Silwan's 150 years of excavation, reaching new heights of tension with the escalating geopolitical conflict between Israelis and Palestinians. As a case study, explorations in the City of David (figure 1), demonstrate how professional interests increasingly compromise and indeed violate the needs and rights of those who are most closely tied to, and indeed dependent on, the locus of exploration (Galor 2017, 126–131). Silwanis, both the small minority of Jewish settlers and the predominantly Palestinian population, have been persuaded and largely misguided as to the area's biblical heritage. In contrast, the 1300-years of nearly continuous Islamic presence, is perceived by neither as a legacy, which can be archaeologically explored and publicly validated.
After Liberal Hegemony: The Advent of a Multiplex World Order
Authors: Acharya Amitav
Published: September 2017

While the West woke up to the threat to the liberal international order when Donald Trump was elected U.S. president, its decline was apparent even at the height of the Obama-Clinton era. What follows the end of the U.S.-dominated world order is not a return to multipolarity as many pundits assume. The twenty-first-century world—politically and culturally diverse but economically and institutionally interlinked—is vastly different from the multipolar world that existed prior to World War II. China and India are major powers now; and globalization will not end, but will take on a new form, driven more by the East than the West and more by South-South linkages than North-North ones. The system of global governance will fragment, with new actors and institutions chipping away at the old UN-based system. Liberal values and institutions will not disappear, but will have to coexist and enmesh with the ideas and institutions of others, especially those initiated by China. This “multiplex world” carries both risks and opportunities for managing international stability. Instead of bemoaning the passing of the old liberal order, the West should accept the new realities and search for new ways to ensure peace and stability in partnership with the rising powers.
The Idea of Europe as the Point of Encounter between Power and Freedom, Interests and Universal Values: A Consideration of Kissinger’s and Ratzinger’s Visions of Europe
Authors: Frances McKenna Mary
Published: September 2017

The aim of this article is to contribute to thinking on pre-political foundations of secular societies. I do so through the idea of Europe. The importance of pre-political foundations relates to power and freedom, specifically how freedom truly can be freedom and not ultimately power. The paper includes two sections: Section 1 discusses Europe’s Westphalian system as the model for global international relations. Henry Kissinger’s proposal that a modern Westphalian system should be adopted by the international community, as outlined in his 2014 World Order Reflections on the Character of Nations and the Course of History, is explored and critiqued. Section 2 looks at an alternative vision of Europe as the global template which addresses many of the open issues identified in Kissinger’s proposal. Joseph Ratzinger/Pope Emeritus Benedict XVI sees Europe as a historical and cultural idea with, as pre-political foundation, the primacy of rationality as creative reason. Ratzinger’s vision does not displace Kissinger’s; rather it informs it. Core to this discussion are freedom, power, interests and universal values, specifically how these four components interact and can be managed to produce positive constructive outcomes; ultimately these interactions relate to the pre-political foundations that orientate societies.
The Evolving Islam and Psychology	Movement
Authors: Kaplick Paul M. , Skinner Rasjid
Published: September 2017

Abstract. Since the late 1970s there has been a growing awareness in academic literature, and particularly among Muslim psychologists, of the relationship between Islam and psychology. Indicated by almost 40 years of publications and debates, this progression of interest has pointed toward the potential establishment of an Islam and psychology movement within the landscape of psychological sciences. We provide a narrative review that outlines the constitutive elements and appraises the current state of the field. Attention is given to the predominantly-involved professionals, academics, and associations; as well as to the definition of its subject matter and conceptual approaches. We conclude by summarizing current opinions on how the movement may successfully evolve.
What reward does a child prefer for behaving well at the dentist?
Authors: Coxon James , Hosey Marie Therese , Newton Jonathon Timothy
Published: September 2017

Background:

Paediatric dentists often report using positive reinforcement to encourage their young patients to show co-operative behaviour. For effective reinforcement to take place the reward should be salient to the individual. To date, there is little research into what reward a young patient will choose when attending the dentist.

Aim:

To identify what reward children between the age of 4–8 years will choose when attending the dentist, and to determine the extent of agreement between children and caregivers in reward choice.

Method:

Observational study. Fifty-two children from different age groups (4–5 years, 6–7 years and 8 years) attending a primary-care dental clinic were asked to choose between a range of different rewards. The caregiver attending with them was also asked to anticipate the child’s preferred choice.

Results:

There was no clear favourite reward for children from both genders and different age group. However, no child chose the ‘sticker’ reward that is traditionally given out at the dentist. Overall carers agreed with the child’s choice of toy on 18 occasions (34.6%), but there were significant differences across the age groups with carers of older children showing less agreement

Conclusion:

To ensure that rewards are salient, children should be given a choice of rewards when attending the dental clinic. Parents ability to predict their child’s preferred rewards decreases as the child ages.

Clinical relevance:

A child’s motivation to co-operate during dental treatment can be increased by offering a range of rewards. Asking children to choose their reward from a limited range will increase the saliency of the reward for the child.

Adding dilute concentrations of nitrogen (N) or bismuth (Bi) into conventional III–V semiconductor alloys causes a large bowing of the bandgap energy due to the modification of the electronic band structure. This behaviour has attracted significant interest due to the resulting optical and electronic properties. Firstly, the authors present theoretical band structure models for GaAs‐based dilute nitride, dilute bismide and dilute bismide‐nitride alloys and then use them within current continuity equations to show the photovoltaic behaviour . To describe the band structures of these highly mismatched III–V semiconductor alloys, the authors introduce a 10‐, 12‐ and 14‐band Hamiltonian for dilute nitride, dilute bismide and dilute bismide‐nitride semiconductors, respectively. The authors then use this approach to analyse GaBiAs multi‐quantum well p‐i‐n structures for photovoltaic performance. Through theoretical analysis the authors can: (i) elucidate important trends in the properties and photovoltaic performance of GaBiAs QW structures and (ii) comment generally on the suitability of GaBiAs alloys and heterostructures for applications in multi‐junction solar cells. In particular, the authors identify and quantify the limitations associated with current GaBiAs solar cells, and describe the improvements in performance that can be expected pending further development of this emerging class of devices.

Context. The so-called Hα third emission occurs around pulsation phase ϕ = 0.30. It has been observed for the first time in 2011 in some RR Lyrae stars. The emission intensity is very weak, and its profile is a tiny persistent hump in the red side-line profile.

Aims. We report the first observation of the Hα third emission in RR Lyr itself (HD 182989), the brightest RR Lyrae star in the sky.

Methods. New spectra were collected in 2013−2014 with the AURELIE spectrograph (resolving power R = 22 700, T152, Observatoire de Haute-Provence, France) and in 2016−2017 with the eShel spectrograph (R = 11 000, T035, Observatoire de Chelles, France). In addition, observations obtained in 1997 with the ELODIE spectrograph (R = 42 000, T193, Observatoire de Haute-Provence, France) were reanalyzed.

Results. The Hα third emission is clearly detected in the pulsation phase interval ϕ = 0.188−0.407, that is, during about 20% of the period. Its maximum flux with respect to the continuum is about 13%. The presence of this third emission and its strength both seem to depend only marginally on the Blazhko phase. The physical origin of the emission is probably due to the infalling motion of the highest atmospheric layers, which compresses and heats the gas that is located immediately above the rising shock wave. The infalling velocity of the hot compressed region is supersonic, almost 50 km s-1, while the shock velocity may be much lower in these pulsation phases.

Conclusions. When the Hα third emission appears, the shock is certainly no longer radiative because its intensity is not sufficient to produce a blueshifted emission component within the Hα profile. At phase ϕ = 0.40, the shock wave is certainly close to its complete dissipation in the atmosphere.

Context. Massive stars with solar metallicity lose important amounts of rotational angular momentum through their winds. When a magnetic field is present at the surface of a star, efficient angular momentum losses can still be achieved even when the mass-loss rate is very modest, at lower metallicities, or for lower-initial-mass stars. In a close binary system, the effect of wind magnetic braking also interacts with the influence of tides, resulting in a complex evolution of rotation.

Aims. We study the interactions between the process of wind magnetic braking and tides in close binary systems.

Methods. We discuss the evolution of a 10 M⊙ star in a close binary system with a 7 M⊙ companion using the Geneva stellar evolution code. The initial orbital period is 1.2 days. The 10 M⊙ star has a surface magnetic field of 1 kG. Various initial rotations are considered. We use two different approaches for the internal angular momentum transport. In one of them, angular momentum is transported by shear and meridional currents. In the other, a strong internal magnetic field imposes nearly perfect solid-body rotation. The evolution of the primary is computed until the first mass-transfer episode occurs. The cases of different values for the magnetic fields and for various orbital periods and mass ratios are briefly discussed.

Results. We show that, independently of the initial rotation rate of the primary and the efficiency of the internal angular momentum transport, the surface rotation of the primary will converge, in a time that is short with respect to the main-sequence lifetime, towards a slowly evolving velocity that is different from the synchronization velocity. This “equilibrium angular velocity” is always inferior to the angular orbital velocity. In a given close binary system at this equilibrium stage, the difference between the spin and the orbital angular velocities becomes larger when the mass losses and/or the surface magnetic field increase. The treatment of the internal angular momentum transport has a strong impact on the evolutionary tracks in the Hertzsprung-Russell Diagram as well as on the changes of the surface abundances resulting from rotational mixing. Our modelling suggests that the presence of an undetected close companion might explain rapidly rotating stars with strong surface magnetic fields, having ages well above the magnetic braking timescale. Our models predict that the rotation of most stars of this type increases as a function of time, except for a first initial phase in spin-down systems. The measure of their surface abundances, together, when possible, with their mass-luminosity ratio, provide interesting constraints on the transport efficiencies of angular momentum and chemical species.

Conclusions. Close binaries, when studied at phases predating any mass transfer, are key objects to probe the physics of rotation and magnetic fields in stars.
Properties of six short-period massive binaries: A study of the effects of binarity on surface chemical abundances
Authors: Martins F. , Mahy L. , Hervé A.
Published: September 2017

Context.A significant percentage of massive stars are found in multiple systems. The effect of binarity on stellar evolution is poorly constrained. In particular, the role of tides and mass transfer on surface chemical abundances is not constrained observationally.

Aims.The aim of this study is to investigate the effect of binarity on the stellar properties and surface abundances of massive binaries.

Methods.We performed a spectroscopic analysis of six Galactic massive binaries. We obtained the spectra of individual components via a spectral disentangling method and subsequently analyzed these spectra by means of atmosphere models. The stellar parameters and CNO surface abundances were determined.

Results.Most of these six systems are comprised of main-sequence stars. Three systems are detached, two are in contact, and no information is available for the sixth system. For 11 out of the 12 stars studied, the surface abundances are only mildly affected by stellar evolution and mixing. The surface abundances are not different from those of single stars within the uncertainties. The secondary of XZ Cep is strongly chemically enriched. Considering previous determinations of surface abundances in massive binary systems suggests that the effect of tides on chemical mixing is limited, whereas the mass transfer and removal of outer layers of the mass donor leads to the appearance of chemically processed material at the surface, although this is not systematic. The evolutionary masses of the components of our six systems are on average 16.5% higher than the dynamical masses. Some systems seem to have reached synchronization, while others may still be in a transitory phase.
Massenanfall von Verletzten – Besonderheiten von „bedrohlichen Lagen“

Terroristische Anschläge oder Amokläufe können Notärzte, Rettungsdienste, Feuerwehren und Katastrophenschutz in „bedrohliche Lagen“ bringen. Die Zusammenarbeit mit der Polizei ist dabei von herausragender Bedeutung. Um die Gefährdung für Hilfskräfte und Betroffene so gering wie möglich zu halten, richtet sich die notfallmedizinische Versorgung nach einsatztaktischen Grundsätzen. Als oberste Strategie bei solchen „bedrohlichen Lagen“ gilt: „Stopp the bleeding and clear the scene“. Die Polizei unterscheidet drei Gefährdungsbereiche: unsicher, teilsicher und sicher. Die Versorgung in diesen Bereichen folgt dem Konzept des Tactical Combat Casualty Care. Während im unsicheren Bereich ausschließlich Polizei eingesetzt werden sollte, kann nach entsprechenden Absprachen der Rettungsdienst im teilsicheren Bereich agieren. Sicherheit wird unter Umständen erst in Notaufnahmen erreicht, die durch verschiedene Maßnahmen zu sicheren Bereichen gemacht werden sollen.
Liquid bridging of cylindrical colloids in near-critical solvents
Authors: Labbé-Laurent M. , Law A. D. , Dietrich S.
Published: September 2017

Within mean field theory, we investigate the bridging transition between a pair of parallel cylindrical colloids immersed in a binary liquid mixture as a solvent that is close to its critical consolute point Tc. We determine the universal scaling functions of the effective potential and of the force between the colloids. For a solvent that is at the critical concentration and close to Tc, we find that the critical Casimir force is the dominant interaction at close separations. This agrees very well with the corresponding Derjaguin approximation for the effective interaction between the two cylinders, while capillary forces originating from the extension of the liquid bridge turn out to be more important at large separations. In addition, we are able to infer from the wetting characteristics of the individual colloids the first-order transition of the liquid bridge connecting two colloidal particles to the ruptured state. While specific to cylindrical colloids, the results presented here also provide an outline for identifying critical Casimir forces acting on bridged colloidal particles as such and for analyzing the bridging transition between them.

The voltage modulation in spin dynamics via the spin-lattice coupling (SLC) effect has been investigated in epitaxial La0.5Sr0.5MnO3/PMN-PT multiferroic heterostructures. The critical angle for the disappearance of the first exchange (FEX) spin wave has been observed around 67° experimentally and been shifted about 4° by applying an electric field (E-field). In particular, at the critical angle, the FEX spin wave can be switched “on” and “off” by voltages, showing great potential in realizing magnonic devices. Moreover, the FEX spin wave resonance shift of 187 Oe at 173 K has been realized by the voltage driven SLC effect, which is a little larger than piezostrain-induced ferromagnetic resonance shift of 169 Oe. The experimental results can be well-explained by the modified Puszkarski spin wave theory.
