Measuring Cultural Responsiveness in the Classroom Component of a School-wide Model of Positive Behavior Support at the Elementary Level
Authors: Utley Cheryl A. 
Published: December 2012

Abstract This study was designed to measure teachers’ self-assessment of elements across 4 domains and compliance in implementing a school-wide positive behavior support (SWPBS) features in an urban elementary school. Within the classroom domain, teachers’ perceptions of cultural responsiveness (CR) were assessed. The participants were 14 teachers and 335 students in kindergarten through fifth grade. The participants were administered the Effective Behavior Survey(EBS), Systems Evaluation Tool (SET), and the Culturally Responsive Survey (CRS). Results of the EBS and SET revealed that (a) participants reported 63% of school-wide, 50% of non-classroom, 59% of classroom, and 24% of individual systems were in place and; (b) fidelity of implementation was 90%, indicating that participants were in compliance with the SWPBS program; and (b) 50% of the participants were perceived as CR, 57% employed CR instructional designs, 63% engaged in CR interactional styles, and 73% employed CR teaching practices

Authors: Stebleton Michael J. , Soria Krista M. , Aleixo Marina B. , Huesman Ronald L. 
Published: December 2012

Abstract This study examined student-faculty interactions and peer interactions among immigrant college students attending 4-year research universities in the United States. Using the Student Experience in the Research University (SERU) survey completed by 58,000 undergraduate students from six large, public research universities, the researchers used analysis of variance and multiple linear regression analyses to explore differences between immigrant populations. The results suggest that there are significant differences between immigrant and non-immigrant college students with regard to their sense of belonging, faculty interactions, and peer interactions. There are also differences within immigrant waves and generational status. Implications and recommendations for educators in multicultural learning and teaching contexts are outlined.
Material schmecken: Die Materialsammlung der ETH Zürich – ein Kooperationsprojekt der ETH-Bibliothek mit dem Departement Architektur und dem Netzwerk Material-Archiv
Authors: Joachim Markus 
Published: December 2012

Abstract
The Materials Collection is newly established at the ETH-Bibliothek in Zurich in cooperation with the Department of Architecture. As part of the Baubibliothek (building library), the collection presents a publicly accessible, systematically structured exhibition of sample materials that offers a unique symbiosis with the corresponding literary and media holdings. The collection ranges from basic, historical materials to the most important materials used in the built environment today, right down to the latest materials in the technological vanguard. To supplement the physical objects, collaboration with the network Material-Archiv (Materials Archive Association) has provided a material-specific database which details the technical characteristics and contexts of the materials and products. This joint project was launched in 2011. The collection is continually expanding and already includes about 1000 objects.

Compact dual-band spectrograph
Authors: Pavlycheva Nadezhda K. , Muslimov Eduard R. 
Published: December 2012

Abstract
A concept and design method of a dual-band flat-field spectrograph is presented. In the proposed optical scheme, the working range of wavelengths is divided into two subranges. A reflection holographic grating is used in the first subrange, and a transmission concave holographic grating is used in the second one. Both of them are aberration-corrected flat-field gratings. As an example, a scheme of spectrograph for spectral range from 278 to 560 nm is considered.
Aristotle on Fire Animals (Generation of Animals iii 11, 761b16-24)
Authors: Macfarlane Patrick 
Published: December 2012

Abstract In a short passage in Generation of Animals iii 11, 761b16-24, Aristotle appears to argue for the existence of life on the moon, or what commentators call ‘fire animals’. Just what this passage is supposed to mean is far from clear. This paper provides the background for Aristotle’s notion of fire animals in his predecessors, including Plato and the Presocratics, and then traces the theme into late antiquity. The paper also integrates the topic of fire animals into Aristotle’s natural philosophy. Finally, the paper demonstrates that Aristotle’s remarks on fire animals provide a unique window into his natural philosophy, particularly his cosmology.
Problēmata Mēchanika, the Analytics, and Projectile Motion
Authors: Anders John 
Published: December 2012

Abstract The project of this paper is to look at problēmata in the Organon, how the Mēchanika employs problēmata, what these texts can teach us about each other, and the significance of all these things for the difficulties that Aristotelian natural philosophy encounters in explaining projectile motion. My treatment of the last item will highlight a pun used in the Mēchanika and argue that it makes a serious point. The paper proceeds as follows: first I will briefly present a reading of how problēmata are understood by Aristotle in the Organon. Next I will examine how problēmata are treated in the Mēchanika. Then I will put these two views of problēmata in dialogue with each other. Lastly I will utilize this discussion to address some of the well-known difficulties associated with Aristotle’s account of projectiles, and what this might mean for Aristotelian natural philosophy as a whole.

Combined effects of CO2, temperature, irradiance and time on the physiological performance of Chondrus crispus (Rhodophyta)

Published: December 2012

Abstract
In natural environments, marine biotas are exposed to a variety of simultaneously acting abiotic factors. Among these, temperature, irradiance and CO2 availability are major factors influencing the physiological performance of marine macroalgae. To test whether elevated levels of CO2 may remediate the otherwise reduced performance of uncalcified seaweeds under the influence of other stressful abiotic factors, we performed multi-factorial experiments with the red alga Chondrus crispus from Helgoland (North Sea) with two levels of CO2, temperature and irradiance: low and high pCO2 levels were tested in combination with either (1) optimal and low irradiances or (2) optimal and sub-lethal high temperatures for growth. Performance of C. crispus was evaluated as biomass increase and relative growth rates (RGR), gross photosynthesis and pigment content. Acclimations of growth and photosynthesis were measured after 4 and 8 days. Acclimation time was crucial for elucidating single or combined CO2 effects on growth and photosynthesis. Significant CO2 effects became evident only in combination with either elevated temperature or reduced irradiance. Growth and photosynthesis had divergent patterns: RGR and biomass significantly increased only under a combination of high pCO2 and elevated temperature; gross photosynthesis was significantly reduced under high pCO2 conditions at low irradiance. Pigment content varied in response to irradiance and temperature, but was independent of pCO2.

Published: December 2012

AbstractBackground:Clinical guidelines for decision-making in chronic kidney disease (CKD) consider parathormone (PTH) levels. The measured PTH values differ if novel full length PTH(1-84) assays are used instead of earlier intact iPTH assays. In this study we analyzed how the classification of CKD patients alters when iPTH assays are switched to PTH(1-84) assays.Methods:Plasma samples were collected prior to dialysis sessions from 110 consecutive CKD patients on maintenance hemodialysis. PTH levels were determined with iPTH assays (Elecsys, Architect and DiaSorin Liaison N-tact) and PTH(1-84) assays (Elecsys and Liaison). Using KDIGO guidelines patients were classified as being below, above and in the recommended target range (RTR) of PTH. The results of classification with different assays were evaluated and, a novel calculation method of RTR was implemented.Results:The prevalence of patients with PTH in RTR is comparable with each assay, but the individual patients differed. PTH(1-84) Elecsys and Liaison assays classified more patients as being below RTR than iPTH Elecsys and Architect but not Liaison N-tact assay (27.3%, 22.7% vs. 41%, 31.8%, and 36.4%, respectively). In turn, PTH(1-84) Elecsys and Liaison assays identified less CKD patients with PTH above the RTR than iPTH except N-tact assays (6.4%, 10% vs. 16.3%, 19%, and 6.3%, respectively). Using our calculation method, our discrimination values for PTH(1-84) assays to achieve classification identical to that with iPTH Elecsys were lower than those recommended by the manufacturer.Conclusions:Current guidelines for the treatment of secondary hyperparathyroidism in CKD should consider the type of assays used for PTH measurement. Each laboratory should assess its own RTR for PTH tests to achieve comparable classification. The presented calculation is simple, it mimics an everyday situation, switching from one assay to another one, and provides useful RTR values for PTH tests.
Analysis of serous body fluids using the CELL-DYN Sapphire hematology analyzer

Published: December 2012

Abstract

Background: Correct cell enumeration and differential analysis of body fluids are important in the diagnosis and management of several diseases. Currently, microscopic analysis is still considered the “gold standard”. The aim of the present study was to evaluate the analytical performance of the CELL-DYN Sapphire hematology analyzer for automated differentiation of cells in serous fluids and to explore whether manual analysis of the raw data files could improve the differential count compared with reference microscopy.

Methods: A total of 105 serous fluids (39 peritoneal and 66 pleural effusions) were analyzed by the CELL-DYN Sapphire using standard whole-blood algorithm. Additionally, we performed optimized manual gating of the Sapphire raw data file using standard flow cytometry software.

Results: The standard Sapphire algorithm showed substantial deviations from the reference microscopic differentiation: polymorphonuclear cell counts were too high because they contained some monocytic cells. However, when optimized manual gating strategy is used, a good correlation and negligible bias were found.

Conclusions: We have demonstrated that with a modified algorithm, CELL-DYN Sapphire will provide reliable identification and enumeration of blood cells in peritoneal and pleural fluids
Advancing haemostasis automation – successful implementation of robotic centrifugation and sample processing in a tertiary service hospital
Authors: Sédille-Mostafaie Nazanin , Engler Hanna , Lutz Susanne , Korte Wolfgang 
Published: December 2012

Abstract

Background: Laboratories today face increasing pressure to automate operations due to increasing workloads and the need to reduce expenditure. Few studies to date have focussed on the laboratory automation of preanalytical coagulation specimen processing. In the present study, we examined whether a clinical chemistry automation protocol meets the preanalytical requirements for the analyses of coagulation.

Methods: During the implementation of laboratory automation, we began to operate a pre- and postanalytical automation system. The preanalytical unit processes blood specimens for chemistry, immunology and coagulation by automated specimen processing. As the production of platelet-poor plasma is highly dependent on optimal centrifugation, we examined specimen handling under different centrifugation conditions in order to produce optimal platelet deficient plasma specimens. To this end, manually processed models centrifuged at 1500 g for 5 and 20 min were compared to an automated centrifugation model at 3000 g for 7 min.

Results: For analytical assays that are performed frequently enough to be targets for full automation, Passing-Bablok regression analysis showed close agreement between different centrifugation methods, with a correlation coefficient between 0.98 and 0.99 and a bias between –5% and +6%. For seldom performed assays that do not mandate full automation, the Passing-Bablok regression analysis showed acceptable to poor agreement between different centrifugation methods.

Conclusions: A full automation solution is suitable and can be recommended for frequent haemostasis testing.

Published: December 2012

Abstract
Congenital hemangiomas (CHs) are rare benign vascular tumors that are present at birth after full development in utero. With the increasing importance of prenatal screening and improved imaging techniques, vascular tumors will be detected more frequently during examination. Ultrasonographers and obstetricians should be aware of these vascular tumors, their differential diagnosis and prognosis. Not only caregivers need optimal counseling, but also the professionals involved should have knowledge about these anomalies because of an increased risk of complications during and after the delivery of the child. Here, we present a child with a CH of the leg and discuss prenatal diagnosis, intra-partum management, and postnatal follow-up.
Near abelian profinite groups
Authors: Hofmann Karl H. , Russo Francesco G. 
Published: December 2012

Abstract
A compact p-group G (p prime) is called
near abelian if it contains
an abelian normal subgroup A such that G/A has a dense cyclic
subgroup and that every closed subgroup of A is normal in G. We relate near abelian groups to a class of compact groups, which are rich in permuting subgroups. A compact group is called quasihamiltonian (or modular)
if every pair of compact subgroups commutes setwise. We show that for p ≠ 2 a compact p-group G is near abelian
if and only if it is quasihamiltonian. The case p = 2 is discussed separately.

Authors: Piroyan Aleksandr , Melikyan Gagik 
Published: December 2012

Abstract
A new efficient method of synthesizing 3-cyano-pyridine-2(1H)-ones containing variable substituents at position 4 and various aromatic substituents at position 1 of the pyridinone ring has been developed. The method is based on the reaction of ylidenecyanoacetic acid ethyl esters with dimethylformamide dimethyl acetal, the re-amination of obtained derivatives with several aromatic amines in glacial acetic acid and the final cyclization of the intermediate products to targeted N-aryl-3-cyano-pyridine-2(1H)-ones. The condensation reactions of some of the synthesized compounds with several aldehydes have been investigated.
Development and evaluation of new curing agents derived from glycerol for formaldehyde-free soy-based adhesives in wood composites
Authors: Huang Jian , Gu Kai , Li Kaichang 
Published: December 2012

Abstract
Three novel curing agents (I, II, and III) were synthesized from epichlorohydrin and ammonium hydroxide. The combinations of soy flour (SF) with one of the curing agents (SF-I, SF-II, and SF-III) were investigated as adhesives for making interior plywood. Water resistance tests showed that plywood panels bonded with SF-I and SF-III adhesives met the requirements of interior plywood, whereas those bonded with SF-II did not. The modulus of rupture, modulus of elasticity, and internal bond strength of particleboard panels bonded with the SF-II adhesive all exceeded the corresponding minimum industrial requirements for M-2 grade particleboard.
Aggregation and adsorption behaviors of carboxymethylated lignin (CML) in aqueous solution

Published: December 2012

Abstract
Carboxymethylated lignin (CML) as a water-soluble lignin derivative is a multipurpose adsorbent and dispersant. In this article, the aggregation and adsorption behaviors of CML have been investigated in aqueous solution using fluorescence spectroscopy, dynamic light scattering, and a quartz crystal microbalance combined with dissipation monitoring techniques. It was found that CML forms aggregates when its concentration exceeds the critical aggregation concentration (CAC). The CAC of CML1 with a carboxylic (COOH) group content of 2.8 mmol g-1 was 0.022 g l-1, and that of CML2 with a COOH group content of 2.0 mmol g-1 was 0.026 g l-1. The adsorption behavior of CML on the gold surface was strongly dependent on the pH and ionic strength of the solution. At low pH and ionic strength, more CMLs were adsorbed at the gold/water interface, and the layers were rigid. The results could be used not only from the theoretical but also from the application point of view.

Published: December 2012

Abstract
Microorganism-based biological protections are alternatives to chemical treatments. Worldwide, Fusarium species are important plant pathogens, and their mycotoxins are antimicrobial. In this study, 18 Fusarium strains isolated in Korea have been investigated. Nine Fusarium species, including two unknown species, were identified based on their genotypic characteristics. Among the identified species, Fusarium
armeniacum and Fusarium commune were observed for the first time in Korea. The antifungal activity of Fusarium crude extracts was assessed by growth inhibition against two wood-decay fungi and three sapstain fungi. Most Fusarium strain extracts revealed strong antifungal activity against wood-decay fungi. Strains of the unknown Fusarium sp. 2, which was found in wood samples, showed strong antifungal activity against all wood-decay and sapstain fungi tested in this study.
Formation of highly hydrophobic wood surfaces using silica nanoparticles modified with long-chain alkylsilane
Authors: Wang Xiaoqing , Chai Yubo , Liu Junliang 
Published: December 2012

Abstract
The so-called lotus effect has inspired the production of highly hydrophobic wood surfaces based on a two-step process consisting of growing nanofilms on the wood substrate (Chinese fir) with silica sol followed by hydrophobization with hydrolyzed hexadecyltrimethoxysilane (HDTMS). The microstructure and chemical composition of the nanofilm coating were examined by field emission scanning electron microscopy, energy dispersive X-ray and Fourier transform infrared spectroscopy. The hydrophobicity of the treated wood was evaluated by water contact angle measurements. The results show that spherical nanoparticles were deposited uniformly on the wood surface, and the long-chain hydrophobic HDMTS was covalently linked to the surface of silica particles. The elevated hydrophobicity of wood was manifested by the water CA of about 141° on the longitudinal surface and 150° on the transverse surface.
Combination of quercetin and tannic acid in inhibiting 26S proteasome affects S5a and 20S expression, and accumulation of ubiquitin resulted in apoptosis in cancer chemoprevention
Authors: Chang Tsui-Ling , Wang Chi-Hsien 
Published: December 2012

Abstract
To look for oral proteasome inhibitors, daily injested food is the best source for cancer chemoprevention. A combination of active components from vegetables, coffee, tea, and fruit could be more efficient to inhibit 26S proteasome activities for preventing cancer diseases. Tannic acid and quercetin have been shown to strongly inhibit 26S proteasome activity, but the molecular target involved remains unknown. Overlay assay, peptide assay, Western blot, and 2-D gels were used to assess the combination of quercetin and tannic acid as a potential inhibitor. Here, we demonstrated that the combination of quercetin and tannic acid (1) synergistically suppresses chymotrypsin-, caspase-, and trypsin-like proteolytic activities, (2) are tightly binding substrates, (3) do not perturb the proteasome structure, (4) inhibit the 26S proteasome affected by ubiquitin, ATP, or β-casein, and (5) inhibit β-casein degradation by the 26S proteasome in vitro. Finally, the inhibition of the proteasome by a combination of quercetin plus tannic acid in Hep-2 cells resulted in the induction of S5a at low dose, accumulation of ubiquitin, and the cleavage of pro-caspase-3, followed by the induction of apoptotic cell death. Evaluating the combination of quercetin and tannic acid as an oral drug to prevent cancer may provide a pharmacological rationale to pursue preclinical trials of this combination.
Plant cell microcompartments: a redox-signaling perspective
Authors: Zachgo Sabine , Hanke Guy T. , Scheibe Renate 
Published: December 2012

Abstract
This review describes how transient protein-protein interactions can contribute to direct information flow between subsequent steps of metabolic and signaling pathways, focusing on the redox perspective. Posttranslational modifications are often the basis for the dynamic nature of such macromolecular aggregates, named microcompartments. The high cellular protein concentration promotes these interactions that are prone to disappear upon the extraction of proteins from cells. Changes of signaling molecules, such as metabolites, effectors or phytohormones, or the redox state in the cellular microenvironment, can modulate them. The signaling network can, therefore, respond in a very flexible and appropriate manner, such that metabolism, stress responses, and developmental steps are integrated by multiple and changing contacts between functional modules. This allows plants to survive and persist by continuously and flexibly adapting to a challenging or even adverse environment.
