Arkitektur og pedagogikk i samspill eller motspill? - om betydning av koherens mellom planlegging og etablering av nye typer barnehagebygg
Authors: Evenstad Randi , Becher Aslaug Andreassen 
Published: September 2015

Abstract: This article discusses the intentions and experiences from architects and pedagogues involved in planning and establishing kindergartens with new building topologies in Oslo. The National Kindergarten effort (St.meld.nr. 24 2002-2003) with the political aim that all children between one and six years should have the right to attend kindergarten, led to a huge development of kindergarten buildings all over Norway. Many of the buildings were designed as new typologies named base and zone kindergartens. There are barely research on processes and consequences of the changes in physical structures in educational institutions. The results of the research presented here are based on a case study of processes in four municipalities in Oslo. It shows that the staff working in the new buildings had scarcely any knowledge of the intentions behind the new design, and the support in establishing pedagogical work in new physical frames was limited. The aim of the article is to expand the knowledge about connections between architecture and pedagogic, and point to the importance of involving the staff/professionals in educational changes where the physical environment is at stake. These findings may be relevant to other transformations involving organizational and architectural changes. Sammendrag: Artikkelen drøfter intensjoner og erfaringer hos arkitekter og pedagoger involvert i planlegging og etablering av barnehager med nye bygningstypologier i Oslo. Barnehageforliket (St.meld.nr.24 2002-2003) innebar et politisk vedtak om barnehageplass for alle og førte til en massiv utbygging av barnehager over hele landet. Mange av de nye byggene ble oppført med nye typer planløsninger (base- og sonebarnehager). Det finnes lite forskning om prosesser og konsekvenser knyttet til endring av fysiske strukturer i pedagogiske institusjoner. Forskningsresultatene som presenteres i artikkelen er basert på en casestudie av prosesser i fire bydeler i Oslo, og viser at personalet i de nye byggene hadde lite kjennskap til intensjoner bak byggenes utforming og opplevde lite støtte i etableringsprosessen. Artikkelens formål er å bidra til kunnskap om betydningen av å involvere personalet i pedagogiske reformer og i utvikling av det fysiske miljøet. Funnene kan ha overføringsverdi til andre reformer som innebærer organisatoriske og arkitektoniske endringer.

AbstractIn this study, land cover changes between 1972 and 2013 were investigated in the Binah River watershed (North of Togo and Benin) using remote sensing and geographic information system technologies. Multitemporal satellite images—Landsat MSS (1972), TM (1987), and OLI‐TIRS (2013)—were processed using object‐based image analysis and post–classification comparison methods including landscape metrics and changes trajectories analysis. Land cover maps referring to five main land cover classes, namely, agricultural land, forest land, savannah, settlements, and water bodies, were produced for each acquisition date. The overall accuracies were 76.64% (1972), 83.52% (1987), and 88.84% (2013) with respective Kappa statistics of 0.69, 0.78, and 0.86. The assessment of the spatiotemporal pattern of land cover changes indicates that savannah, the main vegetation type, has undergone the most dominant change, decreasing from 67% of the basin area in 1972 to 56% in 1987 and 33% in 2013. At the same time, agricultural land has significantly increased from 15% in 1972 to 24% in 1987 and 43% in 2013, while some proportions of agricultural land were converted to savannah relating to fallow agriculture. In total, more than 55% of the landscape experienced changes between 1972 and 2013. These changes are primarily due to human activities and population growth. In addition, agricultural activities significantly contributed to the increase in the number of patches, degree of division, and splitting index of forest and savannah vegetations and the decrease in their effective mesh sizes. These results indicate further fragmentation of forest and savannah vegetations between 1972 and 2013. Further research is needed to quantitatively evaluate the influences of individual factors of human activities and to separate these from the impacts of climate change‐driven disturbances.
Exhumation of serpentinized peridotite in the northern Manila subduction zone inferred from forward gravity modeling

AbstractThe Taiwan Integrated Geodynamic Research program (TAIGER) collected two wide‐angle and reflection seismic transects across the northern Manila subduction zone that provide constraints on the seismic velocity structure of the crust. Two‐dimensional gravity modeling along these two transects shows a significant, relatively high density (3.12 and 3.02 g/cm3) in the fore‐arc region, at the interface between the subducting Eurasian Plate and the accretionary prism in front of the Luzon arc on the overriding Philippine Sea Plate. The anomalous density in this zone is higher than that in the fore‐arc crust and the accretionary prism but lower than that in mantle. Numerous geophysical and geological data, together with numerical models, have indicated that serpentinization of the fore‐arc mantle is both expected and observed. Serpentinization of mantle rocks can dramatically reduce their seismic velocity and therefore their seismic velocity in a density to velocity conversion. Therefore, the source of the high‐density material could be serpentinized fore‐arc mantle, with serpentinization caused by the dehydration of the subducting Eurasian Plate. We interpret that positive buoyancy combined with weak plate coupling forces in the northern Manila subduction zone is resulting in this serpentinized fore‐arc mantle peridotite being exhumed.

Published: September 2015

AbstractThe purpose of this work is to study neutron enhancements observed using the Neutron Spectrometer aboard MESSENGER in order to identify events that may have been generated at/or near the Sun by solar transients. To securely establish an origin of the observed neutrons that is nonlocal to the MESSENGER spacecraft, a measurement of the energetic ion environment local to MESSENGER is needed. For this purpose, we use energetic ion spectrometers on several spacecraft at 1 AU when they were magnetically connected to MESSENGER during an event. We report strong evidence that for six neutron events studied in detail, the detected neutrons do not likely have a local spacecraft origin. By implication, most of the detected neutrons for these six events may have originated near the Sun, generated by many moderate‐level solar eruptive events that produce an extended solar exosphere of moderate‐energy neutrons, protons, and electrons.

Published: September 2015

AbstractCopper‐catalyzed, aerobic, oxidative, C3‐dicarbonylation of indoles has been realized directly from α‐hydroxyketones, which serve as an efficient dicarbonylative reagent under mild conditions. The method is widely compatibility with various functional groups, offering a straightforward means to produce different heterocycle‐substituted quinoxalines in excellent yields. These diverse fluorescent quinoxalines exhibited photophysical properties and solvatochromism in certain rules. Based on control experiments, a plausible reaction mechanism was proposed.

Published: September 2015

AbstractA series of energetic polynitro‐aryl‐1,2,3‐2 H‐triazoles are synthesized from readily accessible aryl‐1,2,3‐2 H‐triazoles. X‐ray diffraction analysis established the solid‐state structures of several representative molecules. The thermal properties are determined by differential scanning calorimetry and thermogravimetric analysis (DSC‐TGA) data. Based on computational studies, most of the compounds showed positive heats of formation and the densities were 1.55 to 1.83 g cm−3. In addition, the compounds were thermally stable (Td>210 °C) and exhibited acceptable detonation properties.

AbstractDünnschichttransistoren können als bioelektronische Bauelemente genutzt werden, um solche Aufgaben auszuführen wie Erkennung oder Steuerung der Freisetzung biologischer Spezies sowie Umwandlung der elektrischen Aktivität von Zellen oder sogar Organen wie des Gehirns. Organische Materialien sowie Graphen oder Zinkoxid werden als druckbare Halbleiterschicht eingesetzt, was zu leistungsfähigen kostengünstigen bioelektronischen Sensoreinheiten führen kann, die möglicherweise sehr nützlich für Vor‐Ort‐Anwendungen sind. Von Interesse sind unter anderem die elektrolytgesteuerten Transistoren, da sie aufgrund der hohen Kapazität der Ladungsdoppelschichten als kapazitätsmodulierte Bauelemente betrieben werden können. Speziell die Kapazität der Bioschicht, die in einer Reihe von Kondensatoren geringer ist, beeinflusst den Ausgangsstrom des Bauelementes. Solch ein Phänomen ermöglicht eine äußerst hohe Empfindlichkeit gegen sehr schwache Wechselwirkungen. Sämtliche Aspekte, die diese Vorgänge bestimmen, werden besprochen.
Printable Bioelectronics To Investigate Functional Biological Interfaces

Published: September 2015

AbstractThin‐film transistors can be used as high‐performance bioelectronic devices to accomplish tasks such as sensing or controlling the release of biological species as well as transducing the electrical activity of cells or even organs, such as the brain. Organic, graphene, or zinc oxide are used as convenient printable semiconducting layers and can lead to high‐performance low‐cost bioelectronic sensing devices that are potentially very useful for point‐of‐care applications. Among others, electrolyte‐gated transistors are of interest as they can be operated as capacitance‐modulated devices, because of the high capacitance of their charge double layers. Specifically, it is the capacitance of the biolayer, being lowest in a series of capacitors, which controls the output current of the device. Such an occurrence allows for extremely high sensitivity towards very weak interactions. All the aspects governing these processes are reviewed here.
Electrocatalytic Dihydrogen Production with a Robust Mesoionic Pyridylcarbene Cobalt Catalyst
Authors: van der Meer Margarethe , Glais Estelle , Siewert Inke , Sarkar Biprajit 
Published: September 2015

AbstractA CoIII complex with a mesoionic pyridylcarbene ligand is presented. This complex is an efficient electrocatalyst for H2 production at very low overpotential and high turnovers when using a (glassy carbon) GC electrode. The corresponding triazole complexes display no catalytic activity whatsoever under identical conditions. The remarkable robustness of the CoC(carbene) bond towards acids is likely responsible for the high efficiency of this catalyst. The present results thus open new avenues for carbene‐based ligands for generating functional models for hydrogenases.

Published: September 2015

Abstract[Pt(cur)(NH3)2](NO3) (1), a curcumin‐bound cis‐diammineplatinum(II) complex, nicknamed Platicur, as a novel photoactivated chemotherapeutic agent releases photoactive curcumin and an active platinum(II) species upon irradiation with visible light. The hydrolytic instability of free curcumin reduces upon binding to platinum(II). Interactions of 1 with 5′‐GMP and ct‐DNA indicated formation of platinum‐bound DNA adducts upon exposure to visible light (λ=400–700 nm). It showed apoptotic photocytotoxicity in cancer cells (IC50≈15 μM), thus forming ⋅OH, while remaining passive in the darkness (IC50>200 μM). A comet assay and platinum estimation suggest Pt–DNA crosslink formation. The fluorescence microscopic images showed cytosolic localization of curcumin, thus implying possibility of dual action as a chemo‐ and phototherapeutic agent.
Fabrication of elastic composite hydrogels using surface‐modified cellulose nanofiber as a multifunctional crosslinker
Authors: Kobe Ryosuke , Yoshitani Kouzou , Teramoto Yoshikuni 
Published: September 2015

ABSTRACTWe fabricate composite hydrogels using surface‐modified cellulose nanofiber (CNF) and N‐isopropylacrylamide (NIPAm) as a multifunctional crosslinker and monomer, respectively. We expect to produce unique network structures that lead to elastomeric properties rarely reported for CNF‐based materials. The modification of CNF is performed to introduce polymerizable vinyl groups onto the surface of CNF via condensation between the surface hydroxyl groups and 3‐(trimethoxysilyl)propylmethacrylate. The modification and morphology of the surface‐modified CNF (mCNF) are confirmed by FTIR, solid‐state NMR, and FE‐SEM, respectively. We conduct in situ radical polymerization under various conditions using mixtures of the mCNF aqueous suspension, NIPAm monomer, radical initiator, and catalyst. The mechanical properties of the obtained hydrogels (water content = 90 wt %) are evaluated. The gels can be elastically stretched to more than 700 times their original lengths and exhibit an apparent shape recovery with a small permanent deformation (∼1/5 of the applied deformation under the gravity field). © 2015 Wiley Periodicals, Inc.

Published: September 2015

ABSTRACTNew microfibrous materials from polylactide and polyvinylpyrrolidone or polyethylene glycol loaded with the natural polyphenolic compound curcumin have been prepared by one‐pot electrospinning. The incorporation of curcumin in the fibers contributes to shielding curcumin from photodestruction and to enhancement of the mechanical properties of the fibers. Moreover, the formation of hydrogen bonds between curcumin and polyvinylpyrrolidone or polyethylene glycol facilitates the drug release. Curcumin release provides for the antibacterial and anticoagulant activity of the curcumin‐loaded mats and prevents adhesion and aggregation of platelets onto the surface of the mats. © 2015 Wiley Periodicals, Inc.

Authors: Bahramzadeh Alireza , Zahedi Payam , Abdouss Majid 
Published: September 2015

ABSTRACTThe aim of this work was to prepare novel electrospun polystyrene (PS) nanofibrous samples functionalization with acrylamide monomer (AAm) as promising nanoadsorbents by the use of nitrogen gas plasma. To investigate the performance evaluation of the samples for adsorbing cadmium (Cd2+) and nickel (Ni2+) ions, a series of tests in terms of ATR‐FTIR spectroscopy, FE‐SEM, water contact angle (WCA) measurements and atomic adsorption spectroscopy were carried out. The ATR‐FTIR results showed that nitrogen (N2) plasma was an efficient tool because of the formation of functionalized AAm‐PS nanofibrous samples by providing amide (−NCO) and amine (−NH−) groups onto their surfaces. The WCA measurements demonstrated that the N2 plasma‐modified samples in the presence of AAm had a lower contact angle of 42.8º than the other samples. Moreover, FE‐SEM micrpgraph images of AAm‐treated PS nanofibrous samples indicated that approperiate amount of the functional groups onto the samples surfaces were deposited. Afterwards, AAS analysis along with Langmuir and Freundlich's isotherm models revealed that a high adsorption of the ions was occurred at pH 5 in the order Cd2+ (10 mg g−1) > Ni2+ (4.9 mg g−1) by using the nanoadsorbents dosage 1 g L−1 and the metal ions concentration 25 mg L−1. In addition, the obtained results exhibited the Cd2+ and Ni2+ ions removal efficiencies (%R) were increased up to 96% and 94%, respectively with raising the nanoadsorbents dosage. Moreover, the equilibrium adsorption of the ions showed the best fitting by the Freundlich's model. Finally, the desorption of the optimized samples for regenerating them owing to the effective removal of the ions has been confirmed by applying the recyclability test. © 2015 Wiley Periodicals, Inc.

Published: September 2015

AbstractRhodamine is an ideal platform for fluorescence probes owing to its spiro‐lactam framework and excellent photochemical properties. Herein, a novel rhodamine‐based palladium fluorescent chemosensor, Rd‐Eb, showing a fast response time (3 min), high sensitivity for palladium species over other ions, and a low detection limit (1.91×10−7 m), was synthesized. It can act as an obvious colorimetric as well as a fluorescent “off/on” sensor for Pd2+. In addition, it is also an excellent sensor for in vivo imaging of Pd2+ in zebra fish and Daphnia magna, illuminating the impact of palladium on organisms at different growth stages with respect to biological toxicology.

Published: September 2015

AbstractA novel fluorescent sensor based on tetraphenylethene (TPE) modified with 2,6‐pyridinedicarboxylic acid (PDA) that shows aggregation‐induced emission (AIE) characteristics for thorium recognition with remarkable fluoresence enhancement response has been synthesized. This sensor is capable of visually distinguishing Th4+ among lanthanides, transition metals, and alkali metals under UV light. Th4+ can be detected by the naked eye at ppb levels owing to the AIE phenomenon. The sensor showed high selectivity for Th4+ compared to all other metals tested, and this recognition displayed good anti‐interference qualities. This study represents the first application of a AIE fluorescence sensor in actinide metal recognition and it has potential applications in environmental systems for thorium ion detection.

Abstract

Background
The aim was to compare the clinical outcomes and effectiveness of surgical treatments for haemorrhoids.

Methods
Randomized clinical trials were identified by means of a systematic review. A Bayesian network meta-analysis was performed using the Markov chain Monte Carlo method in WinBUGS.

Results
Ninety-eight trials were included with 7827 participants and 11 surgical treatments for grade III and IV haemorrhoids. Open, closed and radiofrequency haemorrhoidectomies resulted in significantly more postoperative complications than transanal haemorrhoidal dearterialization (THD), LigaSure™ and Harmonic® haemorrhoidectomies. THD had significantly less postoperative bleeding than open and stapled procedures, and resulted in significantly fewer emergency reoperations than open, closed, stapled and LigaSure™ haemorrhoidectomies. Open and closed haemorrhoidectomies resulted in more pain on postoperative day 1 than stapled, THD, LigaSure™ and Harmonic® procedures. After stapled, LigaSure™ and Harmonic® haemorrhoidectomies patients resumed normal daily activities earlier than after open and closed procedures. THD provided the earliest time to first bowel movement. The stapled and THD groups had significantly higher haemorrhoid recurrence rates than the open, closed and LigaSure™ groups. Recurrence of haemorrhoidal symptoms was more common after stapled haemorrhoidectomy than after open and LigaSure™ operations. No significant difference was identified between treatments for anal stenosis, incontinence and perianal skin tags.

Conclusion
Open and closed haemorrhoidectomies resulted in more postoperative complications and slower recovery, but fewer haemorrhoid recurrences. THD and stapled haemorrhoidectomies were associated with decreased postoperative pain and faster recovery, but higher recurrence rates. The advantages and disadvantages of each surgical treatment should be discussed with the patient before surgery to allow an informed decision to be made.

AbstractParaquat is quick‐acting and non‐selective, killing green plant tissue on contact; it is also toxic to human beings and animals. In this study, we developed a urine metabonomic method by gas chromatography–mass spectrometry to evaluate the effect of acute paraquat poisoning on rats. Pattern recognition analysis, including both partial least squares discriminate analysis and principal component analysis revealed that acute paraquat poisoning induced metabolic perturbations. Compared with the control group, the levels of benzeneacetic acid and hexadecanoic acid of the acute paraquat poisoning group (intragastric administration 36 mg/kg) increased, while the levels of butanedioic acid, pentanedioic acid, altronic acid decreased. Based on these urinary metabolomics data, support vector machine was applied to discriminate the metabolomic change of paraquat groups from the control group, which achieved 100% classification accuracy. In conclusion, metabonomic method combined with support vector machine can be used as a useful diagnostic tool in paraquat‐poisoned rats. Copyright © 2015 John Wiley & Sons, Ltd.
