Published: October 2018

Рассматривается стимулирующая роль гормона стресса абсцизовой кислоты (АБК) в процессе соматического эмбриогенеза растений - асексуальном формировании зародышей из соматической клетки/группы клеток в экспериментальных условиях культуры in vitro - в сравнении с аналогичными событиями в зиготическом эмбриогенезе в естественных условиях in vivo. Приводятся сравнительные данные об участии АБК в двух путях соматического эмбриогенеза in vitro - прямом и непрямом. Обсуждается влияние АБК на индукцию формирования, стадии развития и прорастание соматических зародышей в сравнении с аналогичными процессами в зиготических зародышах in vivo. Анализируется совместное воздействие АБК и других фитогормонов, а также АБК и осмотических веществ на процесс соматического эмбриогенеза in vitro. Дается оценка возможных клеточных и молекулярных механизмов стимулирующего действия АБК на индукцию и ход соматического эмбриогенеза in vitro. Подтверждается положение о том, что для индукции и поддержания тех или иных физиологических программ растениям необходимо определенное качественное сочетание и количественное соотношение фитогормонов, в частности АБК. Высказывается предложение об использовании соматического эмбриогенеза в контролируемых условиях in vitro как модели для изучения взаимодействия и взаимовлияния фитогормонов в растениях в естественных условиях in vivo.

Published: October 2018

AbstractRoom‐temperature hydro‐pressure‐driven densification of amorphous silica (nanoparticles and microbeads) is developed. This technique is inspired by biological silicification with reference to dissolution, precipitation, and hardening mechanisms. Cold sintering based on uniaxial pressure is taken as a benchmark. Starting from a green‐body relative density of 70%, densification exceeding 99% is achieved by adding distilled water or caustic solution to an amorphous powder under a hydrostatic pressure of 450–600 MPa for 5–30 min. Translucent samples are obtained. Silica microbeads are employed as a model system to define the effect of the sintering parameters: pressure, pH, and soaking time. Densification is attained through a preferential precipitation of a second phase from silica dissolution under hydro‐pressure. Precipitation is governed by minimization of the surface energy (Ostwald ripening). Transmission electron microscopy, NMR, thermal gravimetric analysis/differential scanning calorimetry, and Fourier transform infrared spectroscopy reveal the mechanisms of the process and the analogies with biosilicification.

Published: October 2018

AbstractSoft on‐skin electronics have broad applications in human healthcare, human–machine interface, robotics, and others. However, most current on‐skin electronic devices are made of materials with limited gas permeability, which constrain perspiration evaporation, resulting in adverse physiological and psychological effects, limiting their long‐term feasibility. In addition, the device fabrication process usually involves e‐beam or photolithography, thin‐film deposition, etching, and/or other complicated procedures, which are costly and time‐consuming, constraining their practical applications. Here, a simple, general, and effective approach for making multifunctional on‐skin electronics using porous materials with high‐gas permeability, consisting of laser‐patterned porous graphene as the sensing components and sugar‐templated silicone elastomer sponges as the substrates, is reported. The prototype device examples include electrophysiological sensors, hydration sensors, temperature sensors, and joule‐heating elements, showing signal qualities comparable to conventional, rigid, gas‐impermeable devices. Moreover, the devices exhibit high water‐vapor permeability (≈18 mg cm−2 h−1), ≈18 times higher than that of the silicone elastomers without pores, and also show high water‐wicking rates after polydopamine treatment, up to 1 cm per 30 s, which is comparable to that of cotton. The on‐skin devices with such attributes could facilitate perspiration transport and evaporation, and minimize discomfort and inflammation risks, thereby improving their long‐term feasiblity.

AbstractIn the quest for solutions to enhance the safety and sustainability of energy storage devices, Bombyx mori silkworm cocoons are proposed as separators for lithium (Li)‐ion batteries obtained literally from nature, and employed directly in a device. The suitability of the cocoons is evaluated in Li‐ion batteries using two different electrolytes: a mixture of lithium hexafluorophosphate (LiPF6), ethylene carbonate (EC), and dimethyl carbonate (DMC), and the ionic liquid (IL) 1‐ethyl‐3‐methylimidazolium bis(trifluoromethylsulfonyl)imide ([Emim]TFSI). Li/C–LiFePO4 half cells comprising the EC–DMC–LiPF6 electrolyte present excellent cycling performance, with a discharge capacity up to 86 mAh g−1 and a capacity retention up to 81% after 50 cycles at C rate. Values of 66 mAh g−1 at C/5 and 85% result with [Emim]TFSI, respectively. Separator/electrolyte interactions during battery cycling lead to a decrease of the degree of crystallinity of the cocoon silk fibers, and, in the presence of EC–DMC–LiPF6, to a concomitant increase of the concentration of free PF6− ions. The self‐extinguishing ability of silkworm cocoons represents an additional benefit to batteries, providing fire risk reduction or even suppression. This bio‐inspired work paves the way toward the fabrication of environmentally friendlier separators for next‐generation sustainable and safer Li‐ion batteries.

AbstractAimAs a result of the difficulty in effective prevention of gastroesophageal reflux, no standard reconstruction procedure after proximal gastrectomy (PG) has yet been established. The double‐flap technique (DFT), or Kamikawa procedure, is an antireflux reconstruction procedure in esophagogastrostomy. The efficacy of DFT has recently been reported in several studies. However, these were all single‐center studies with a limited number of cases.MethodsWe conducted a multicenter retrospective study in which patients who underwent DFT, irrespective of disease type and reconstruction approach, at each participating institution between 1996 and 2015 were registered. Primary endpoint was incidence of reflux esophagitis at 1‐year after surgery, and secondary endpoint was incidence of anastomosis‐related complications.ResultsOf 546 patients who were eligible for this study, 464 patients who had endoscopic examination at 1‐year follow up were evaluated for reflux esophagitis. Incidence of reflux esophagitis of all grades was 10.6% and that of grade B or higher was 6.0%. Male gender and anastomosis located in the mediastinum/intra‐thorax were independent risk factors for grade B or higher reflux esophagitis (odds ratio [OR]: 4.21, 95% confidence interval [CI]: 1.44‐10.9, P = 0.0109). Total incidence of anastomosis‐related complications was 7.2%, including leakage in 1.5%, strictures in 5.5% and bleeding in 0.6% of cases. Laparoscopic reconstruction was the only independent risk factor for anastomosis‐related complications (OR: 3.93, 95% CI: 1.93‐7.80, P = 0.0003).ConclusionDouble‐flap technique might be a feasible option after PG for effective prevention of reflux, although anastomotic stricture is a complication that must be well‐prepared for.
Detection of Homologue and Isomer Vapors through Dynamic Reflection Spectra of Hollow Mesoporous Silica Sphere Photonic Crystals

Published: October 2018

AbstractVapors of homologues and isomers with very similar refractive indices can be easily distinguished by using dynamic reflection spectra (DRS) of hollow mesoporous silica sphere (HMSS) photonic crystals (PCs). Different diffusion behaviors render the HMSS PCs with a distinct response to different chemicals vapors, leading to diversity in the evolution of the reflection spectra and their DRS patterns. Therefore, by studying the geometric characteristics and color changes of color‐filled contour maps, as well as the reflection peak shift speeds at different stages, even isomers such as n‐butanol and iso‐butanol, with a refractive index difference of only 0.001, can be recognized. The reflection peak shift speed depends on both the refractive index and the diffusion speed of chemicals. The proposed strategy provides a convenient, accurate, and low‐cost method to detect vapors of homologues and isomers.
Strömungsgeräusche an Fassaden
Authors: Herget Wolfgang , Brandstätt Peter 
Published: October 2018

AbstractAkustische Untersuchungen an Fassadenelementen in einem Windkanal können wichtige Erkenntnisse zu potentiellen Strömungsgeräuschen bei deren Überströmung liefern. Die Quellen für Strömungsgeräusche sind vielfältig und werden oft durch Löcher, Öffnungen, Kanten sowie vibrierende Teile verursacht. Sie können unter Umständen sehr vom Anströmwinkel und einer bestimmten Windgeschwindigkeit abhängig sein. Messungen an verschiedenen Fassadenelementen im Windkanal am Fraunhofer‐Institut für Bauphysik IBP zeigten auch, dass nicht zwangsläufig nur hohe Windgeschwindigkeiten zu Problemen führen. Gerade niedrigere Strömungsgeschwindigkeiten, die zu bestimmten geometrischen Abmessungen passen, können ausgeprägte Lärmquellen bilden. Laut Beaufortskala entspricht eine Windstärke von 10 – 20 m/s schon einem starken bis stürmischen Wind. Bei solch hohen Windgeschwindigkeiten ist das allgemeine Hintergrundgeräusch bereits deutlich angehoben und Geräusche an Fassadenelementen können von diesem maskiert werden. Ein weiterer wichtiger Aspekt ist die meist sehr große Fläche von Fassaden. Wenn bereits an einem Fassadenausschnitt im Windkanal markante Strömungsgeräusche entstehen, ist eine weit höhere Schallabstrahlung am Gebäude zu erwarten. Ziel der akustischen Untersuchungen und Optimierungen an einer windüberströmten Fassade sollte dabei immer sein, sie in Einklang mit dem Design und der Konstruktion der Fassade zu bringen.
Wirkung von Nachhall in Bildungsräumen
Authors: Martin Noemi , Liebl Andreas 
Published: October 2018

AbstractMenschen, welche bspw. aufgrund von Hörstörungen oder eingeschränkten Sprachkenntnissen ein erhöhtes Bedürfnis für gute Hörsamkeit haben, sollten in der Erfüllung dieses Bedürfnisses von der raumakustischen Umgebung unterstützt werden. In der Neufassung der DIN 18041 aus dem Jahr 2016 werden daher Anforderungen an die Nachhallzeit definiert, die je nach Nutzergruppe und Nutzungskontext eines Raumes das Hörverstehen optimal unterstützen sollen. Die in dieser Norm festgelegten Anforderungen basieren auf der Annahme, dass in den oben beschriebenen Fällen von Inklusion eine Verringerung der Nachhallzeit zu einem verbesserten Sprachverstehen führt. Das Projekt „Wirkungen von Nachhall in Bildungsräumen” beschäftigt sich mit der Frage, ob empirisch nachgewiesen werden kann, dass die Anwendung der DIN 18041: 2016 diese Anforderung in der Praxis erfüllt, d. h. ob die definierten Zielwerte ausreichen, um dem Thema Inklusion aus raumakustischer Sicht gerecht zu werden. Die Forschungsfrage wurde sowohl in einer Literaturstudie als auch über die empirische Evaluation in einen Hörversuch adressiert. In diesem Artikel werden die Ergebnisse der Literaturrecherche berichtet.
Elemente zur akustischen Gestaltung von Sporthallen

Published: October 2018

AbstractIn Sporthallen lässt die Akustik in vielen Fällen zu wünschen übrig. Oft beschweren sich die Betroffenen berechtigt über eine schlechte Akustik, geringe Sprachverständlichkeit und viel zu hohe Pegel. Dieser Beitrag behandelt Aspekte und Ansätze, mit denen sich die Anforderungen an die akustische Gestaltung von Sporthallen insgesamt besser erfüllen lassen. Raumakustisch ist eine schallabsorbierende Decke zwar gut, aber nicht ausreichend. Deutlich besser sind schallabsorbierende Flächen möglichst in allen drei Raumrichtungen, z. B. durch die Kombination von Decken und Prallwänden. Die analog zu Prallwänden gestalteten, aber akustisch doch etwas anders funktionierenden Geräteraumtore stellen dabei wirksame Tiefenabsorber dar. Die schallabsorbierende Eigenschaft von Trennvorhängen ist in Mehrfeld‐Sporthallen eine sinnvolle Option. Sie sind großflächig und müssen keine Absorptionsrekorde brechen, um Pegel zu mindern und Flatterechos zu vermeiden. Der Schallschutz zwischen Teilhallen bleibt ein akustischer Dauerbrenner. Die untersuchten Maßnahmen sind unter realen Bedingungen umsetzbar und können bei guter Planung zu einer deutlichen Erhöhung der Schalldämmung zwischen den Teilhallen einer Sporthalle führen. Neben einer angemessenen Schallabsorption sollten die Elemente wie Sportböden und Prallwände, die bei der Nutzung selbst Lärm verursachen, möglichst leise sein. Hierzu liegen jetzt konkrete Messungen und erste Vorschläge zur akustischen Behandlung vor.

Published: October 2018

AbstractDas Fraunhofer‐interne Projekt „BauCycle” entwickelt eine ganzheitliche Verwertungsstrategie für feinkörnigen Bauschutt, welcher bisher meist ungenutzt auf Deponien verbracht wird. In einem ersten Schritt wurde eine Methodik zur „chemischen” Sortierung von Bauschutt kleiner 2 mm entwickelt um Störstoffe wie Gips selektiv aus Beton oder Kalksandstein austragen zu können. Basierend auf den Sortiermöglichkeiten fand die Entwicklung von Bauprodukten mit einem signifikanten Anteil an Bauschutt statt. Es konnte ein Porenbetonstein hergestellt werden bei dem der Primärrohstoff Sand zu 30 Ma.‐Prozent durch feinkörniges Bauschuttmaterial ersetzt werden konnte. Zudem wurde ein Akustikputz für Innenanwendungen entwickelt, welcher absolut vergleichbar zu marktüblichen Produkten ist. Neben der Entwicklung neuer Produkte steht auch die Betrachtung geltender Richtlinien im Hinblick auf den Einsatz von neuentwickelten Baustoffen sowie deren ökologische Wirkung im Fokus. Dazu wurden relevante Indikatoren wie Rohstoffqualität und ‐verfügbarkeit definiert und für eine Modellregion dargestellt. Dies geschah nicht zuletzt unter Berücksichtigung logistischer Parameter. Der finale Schritt im Projekt ist die Implementierung einer Handelsplattform über welche Bauschuttfraktionen bedarfsgerecht angeboten bzw. nachgefragt werden können.

Published: October 2018

AbstractThe medicinal and aromatic plants resources of India are known as a source of economy, sustainable livelihood, and employment for many rural communities. However, perhaps the recognition for medicinal and aromatic plants as a source for sustainable economy generation without linking sustainable marketing orientation, such as branding, is less appropriate. Because, the lack of required marketing orientation is leading challenges for resource sustainability in the sector. Therefore, to address the need of sustainable marketing orientation in the medicinal and aromatic plants sector of India and to conceptualize the branding strategy for the medicinal and aromatic plants resources, this qualitative study, based on the brand heritage of Indian medicinal and aromatic plants, demonstrates the implications of country of origin branding framework to brand the Indian medicinal and aromatic plants. Our study provides a fresh perspective on the branding of natural products and offers strategies for differentiation, competitiveness, and authenticity while trading across the globe.

AbstractTransition‐metal and nitrogen co‐doped carbon materials (M/N/C) have received increasing attention as electrocatalysts for the oxygen reduction reaction (ORR). M/N/C catalysts usually exhibit distinct ORR catalytic activity between acidic and alkaline media. The origin of such pH‐dependent activity is so far unclear. Herein, we investigate the dependence of ORR activity of FePc/C catalysts on the pyrolysis temperature (300–1000 °C) in both acidic and alkaline media to speculate the difference between active sites in the different media. The highest ORR activity is achieved at 800 °C and 500 °C in acidic and alkaline media, respectively. In particular, at 600–800 °C, the ORR activity increases greatly with increasing pyrolysis temperature in acidic medium, whereas it decreases in alkaline medium, indicating different active sites present in the two media. Thermal decomposition analysis of FePc suggests that highly active sites in acidic medium are formed through the decomposition of FePc or Fe‐N4 structures at 600–800 °C after releasing phthalonitrile (C6H5−C2N2), whereas intact FePc or Fe‐N4 incorporated in the carbon matrix are the main active sites in alkaline medium. XPS measurements show that there is a good relationship between the ORR activity and metal N in alkaline medium. This study is of significance to the development of highly active non‐precious metal catalysts.

Published: October 2018

AbstractA nitrogen‐doped porous carbon monolith (N‐PCM) was synthesized following a simple self‐assembly method in a one‐pot hydrothermal process. A solution of hexamethylenetetramine (HMT) in formaldehyde and ammonia was used as partial carbon precursor and nitrogen source, respectively. The monolithic polymer was formed through self‐assembly of formaldehyde and resorcinol catalyzed by ammonia. After the annealing process, the N‐PCM was prepared. The N‐PCM with tailorable macrostructure possessed a high specific surface area (1124 m2 g−1), rich porous structure and reasonable N content (up to 2.1 %). Used as binder‐free all‐carbon supercapacitor electrode, the N‐PCM allowed efficient migration of electrolyte ions and electrons, showing a high specific capacitance up to 202 F g−1 at a current density of 1 A g−1, and favorable capacitance retention (93.5 % capacitive retention after 5000 cycles) in a 6 M KOH solution. This advanced monolith carbon material with high surface area and controllable morphology produced in a simple and efficient method could be used as a promising electrode material for high‐performance supercapacitors.

BackgroundChildhood cancer survivors have an increased risk of cardiovascular disease (CVD) and diabetes mellitus. Because diabetes is a potentially modifiable risk factor for CVD in the general population, it is important to understand how diabetes affects the risk of CVD among childhood cancer survivors.MethodsThis study examined the risk of CVD among survivors with diabetes and 142,742 population comparison subjects. From the national cancer registries of the 5 Nordic countries, 29,324 one‐year survivors of cancer diagnosed before the age of 20 years between 1968 and 2008 were identified. Study subjects were linked to the national hospital registers. The cumulative incidence of CVD was determined with competing risk methods. A Cox proportional hazards model was used to estimate the effects of diabetes and cancer on the hazard of CVD. The interaction between diabetes and cancer was analyzed.ResultsDiabetes was diagnosed in 324 of the 29,324 one‐year survivors, and CVD was diagnosed in 2108. The hazard of diabetes was 1.7 times higher among survivors than comparison subjects (hazard ratio [HR], 1.7; 95% confidence interval [CI], 1.5‐1.9), whereas the HR of CVD was 3.6 (95% CI, 3.3‐3.8) 1 to 15 years after the cancer diagnosis and 1.9 (95% CI, 1.8‐2.0) after more than 15 years. Individuals with diabetes had a 2.4 times higher hazard of CVD (95% CI, 2.1‐2.8) among both survivors and comparison subjects in comparison with individuals without diabetes.ConclusionsChildhood cancer survivors with diabetes have a markedly increased risk of CVD in comparison with survivors without diabetes. However, diabetes does not increase the risk of CVD more in survivors than the general population.
