Authors: Gong W. , Liu K. J. , Zhang C. , Zhu J. H. , He L. 
Published: April 2012

Abstract
Microcellular foamed polypropylene (PP)/SiO2 composites were prepared by using micro-SiO2 and nano-SiO2 particles. The effects of the particle size of SiO2 on the foaming behavior and mechanical properties of the composites were studied based on heterogeneous nucleation theory. The results showed that the silica facilitated the cell nucleation to some extent. The average cell size of 16.3 μm and the cell density of 4.46 × 107 cells/cm3 were achieved for the composite foam at the silica content of 4 wt.%. The plastic deformation of the PP was strongly constrained due to the presence of the nano-silica. The tensile and impact strength of the nano-SiO2 composite foam are larger than those of the micro-SiO2 composite foam due to the high crack propagation resistance in the microcellular PP/nano-SiO2 composite.

Published: April 2012

Abstract
In this work, the mechanical and morphological properties of high density polyethylene (HDPE)/flax fiber composites are reported. In particular, the effect of adding a rubber phase (SBR) in terms of recycled ground tire rubber (GTR) is determined. Samples with different concentrations of flax fibers and rubber powders were prepared. Also, the addition of a coupling agent (SEBS) on both matrix-fiber and matrix-rubber surface adhesion and composite morphology is investigated. The results show an improvement in both matrix-rubber and matrix-fiber surface adhesion after incorporation of the coupling agent leading to improved tensile and flexural properties. Also, impact strength results showed a toughening effect of the HDPE matrix by flax and SBR addition.

Tardigrades have unique stress-adaptations that allow them to survive extremes of cold, heat, radiation and vacuum. To study this, encoded protein clusters and pathways from an ongoing transcriptome study on the tardigrade Milnesium tardigradum were analyzed using bioinformatics tools and compared to expressed sequence tags (ESTs) from Hypsibius dujardini, revealing major pathways involved in resistance against extreme environmental conditions.ESTs are available on the Tardigrade Workbench along with software and databank updates. Our analysis reveals that RNA stability motifs for M. tardigradum are different from typical motifs known from higher animals. M. tardigradum and H. dujardini protein clusters and conserved domains imply metabolic storage pathways for glycogen, glycolipids and specific secondary metabolism as well as stress response pathways (including heat shock proteins, bmh2, and specific repair pathways). Redox-, DNA-, stress- and protein protection pathways complement specific repair capabilities to achieve the strong robustness of M. tardigradum.These pathways are partly conserved in other animals and their manipulation could boost stress adaptation even in human cells. However, the unique combination of resistance and repair pathways make tardigrades and M. tardigradum in particular so highly stress resistant.

Authors: Lohss Isabel , Forsyth Kirsty , Kottorp Anders 
Published: April 2012

Introduction: Occupational therapists working in psychiatry are routinely required to undertake vocational assessments and to support clients into work. To make such efforts successful, the use of evidence-based practice and outcome measures is becoming increasingly important. Objectives: The objectives were to examine the psychometric properties of the Worker Role Interview (WRI, version 10.0) with a psychiatric population in the United Kingdom, particularly its construct validity as a baseline assessment and an outcome measure. Method: Data were collected from 34 psychiatric clients rated by seven occupational therapists. Rasch analysis was used to examine scale validity, validity of therapists' rating patterns of clients, rater consistency, precision of client measurement and the scale's aptitude in detecting different ability levels. Results: All items except one demonstrated acceptable goodness-of-fit to the Rasch model. Over 90% of clients fitted the model. The scale detected five ability levels, but client measures were slightly imprecise. Raters used the scale consistently and implications of rater leniency are discussed. Conclusion: The study provides evidence of construct validity, supporting the use of the WRI as a standardised baseline assessment in a mental health population. Further development of the WRI might be indicated and its usefulness as an outcome measure should be tested with larger samples.

Introduction: This small-scale study explores the experiences of staff and students in using a pyramidal model of peer-assisted and long-arm supervision in a role-emerging practice placement in the United Kingdom (UK). Method: Two final year postgraduate diploma occupational therapy students from a UK university entered into a peer-assisted learning arrangement with two occupational therapy students from a Polish university, with UK university staff acting as long-arm supervisors. The setting was a home for older people with no occupational therapy service. This participatory action research preliminary study used interviews to explore the student and supervisor experiences whilst on placement. Findings and discussion: The findings suggest that high levels of personal and professional development can develop in students when this model is used.
Emergent School Leadership: Creating the Space for Emerging Leadership through Appreciative Inquiry
Authors: Dickerson Mark S. 
Published: April 2012

Much has been written on the importance of increasing leadership capacity in schools and managed systems for leadership development; however, little focus has been given to creating conditions to facilitate the emergence of leadership. This research study examines associations of strength-based reflexive processes to the emergence of educational leadership. Specifically, through qualitative analysis, the author explores the emergence of school leadership during an appreciative inquiry initiative in a large, urban school district and identifies the features of appreciative inquiry that were conducive to such emergence. In addition, the author notes that the initiative also provided participants with many of the elements considered vital to leading a healthy learning community: a greater understanding of the big picture, opportunities for professional reflection and sense making, a safe and affirming learning community, time to dialogue with others in the system regarding their core values and commitments, a collaborative work culture, space for networking, and the freedom to take action. Keywords: Emergent Leadership, Appreciative Inquiry, School Improvement

Quality of life becomes an emphasis in the process to reach vision 2020. However, the loitering culture among Malaysians as early as in the primary school until the higher level institution is still be a critical issue. Therefore, this paper aimed to investigate the factors that influenced secondary school students to loitering. This research involved 261 students from two daily schools in Pahang. Among them, 159 involved in loitering activities by which it means in every 10 students, six loiter. The finding shows that the main factor for them to do loitering is to release tension, and then followed by no activity to do, having fun with friends plus no complete recreational facilities around the community. These four factors may contribute to social problems such as vandalism, young smokers and baby dumping because negative attitude will occur among them whereby, they are starting to smoke and getting involved in other negative values. Besides that, family background and school also contribute to students to start loitering. Thus, the finding of this study is hoped to provide useful information in improving the quality of life especially in the rural area whereby the number of crimes among youngsters is increasing. Keywords : loitering culture; quality of life; social problems; student.

Published: April 2012

Abstract
The occurrence of formaldehyde in sap and wood tissue of treated and untreated maple sugar trees was investigated using GC/MS. Samples were collected at different periods of the 2009 season and at different locations in Quebec, Canada. The natural concentration of formaldehyde found in untreated samples varied according to periods and locations and ranged from below the LOQ to 1.82 mg/kg for sap samples and from 2.39 to 8.92 mg/kg of fresh tissue for wood samples. Late season samples tended to have higher concentrations of formaldehyde. Samples of sap and wood tissue from tapholes treated with solutions of formaldehyde showed increased concentrations of formaldehyde for many days after treatment and were clearly distinct from untreated samples. These results will be useful to elaborate new inspection procedures for sugarbushes to control the illegal use of formaldehyde.
Should the AOAC Use-Dilution Method Be Continued for Regulatory Purposes?
Authors: Omidbakhsh Navid 
Published: April 2012

Abstract
Despite its very poor reproducibility, AOAC INTERNATIONAL's use-dilution method (UDM) for bactericidal activity (AOAC Methods 964.02, 955.14, and 955.15) has been required by the U.S. Environmental Protection Agency (EPA) since 1953 for regulatory purposes, while methods with better reproducibility have been adopted in Canada and Australia. This study reviews UDM from a statistical perspective. Additionally, the test's expected results were compared to those obtained from actual evaluation of several formulations. Significant gaps have been identified in the reproducibility of the test data as predicted by statistical analysis and those presented to the EPA for product registration. UDM's poor reproducibility, along with its qualitative nature, requires the concentration of the active ingredient to be high enough to ensure all or most carriers to be free of any viable organisms. This is not in accord with the current trends towards sustainability, human safety, and environmental protection. It is recommended that the use of the method for regulatory purposes be phased out as soon as possible, and methods with better design and reproducibility be adopted instead.

Authors: Köppel René , Eugster Albert , Ruf Jürg , Rentsch Jürg 
Published: April 2012

Abstract
The quantification of meat proportions in raw and boiled sausage according to the recipe was evaluated using three different calibrators. To measure the DNA contents from beef, pork, sheep (mutton), and horse, a tetraplex real-time PCR method was applied. Nineteen laboratories analyzed four meat products each made of different proportions of beef, pork, sheep, and horse meat. Three kinds of calibrators were used: raw and boiled sausages of known proportions ranging from 1 to 55% of meat, and a dilution series of DNA from muscle tissue. In general, results generated using calibration sausages were more accurate than those resulting from the use of DNA from muscle tissue, and exhibited smaller measurement uncertainties. Although differences between uses of raw and boiled calibration sausages were small, the most precise and accurate results were obtained by calibration with fine-textured boiled reference sausages.

Published: April 2012

Abstract
A sensitive and effective method for the simultaneous quantitative determination of aminopyralid, clopyralid, and picloram in vegetables (eggplant, cucumber, and tomato) and fruits (apple and grape) was developed and validated using ultra-performance LC coupled with MS/MS. The three herbicides were successfully separated and independently confirmed in a single run. Different extraction and cleanup methods were used to optimize the pretreatment processes of the residue analysis method. The final method is straightforward and involves extraction with 1% formic acid–acetonitrile, and no complicated cleanup process is needed. Determination of the compounds was achieved within 3.0 min. Respective average recoveries using this method at four concentration levels (0.05, 0.1, 0.5, and 1.0 mg/kg) ranged from 66.5 to 109.4%, with RSDs in the range of 1.1–19.7% (n = 5) for all analytes. The LODs were below 0.010 mg/kg, and the LOQs did not exceed 0.036 mg/kg, which were lower than the maximum residue limits (MRLs) of 0.5–5.0 mg/kg clopyralid in vegetables and fruits samples, as established by the European Union. This study provides a theoretical basis for China to develop MRLs and an analytical method for aminopyralid, clopyralid, and picloram in vegetables and fruits.

Published: April 2012

Abstract
Bacillus cereus is a group of ubiquitous facultative anaerobic sporeforming Gram-positive rods commonly found in soil. The spores frequently contaminate a variety of foods, including produce, meat, eggs, and dairy products. Foodborne illnesses associated with toxins produced by B. cereus can result in self-limiting diarrhea or vomiting. Plate enumeration methods recommended by recognized food authorities to detect the presence of B. cereus in potentially contaminated food products do not inhibit other Gram-positive competitive bacteria. This study evaluated the use of Bacara, a new chromogenic agar, as an efficient method to identify and enumerate B. cereus group from food matrixes, even in the presence of background flora. Inclusivity and exclusivity testing was performed using four different selective and differential media for B. cereus, including Mannitol Egg Yolk Polymyxin (MYP), Polymyxin Pyruvate Egg-Yolk Mannitol Bromothymol Blue Agar, Bacillus Chromogenic Media, Brilliance, and Bacara. MYP and Bacara were also used in plate enumeration studies to isolate B. cereus from artificially contaminated foods.

Abstract
We have developed a real-time PCR array method to comprehensively detect genetically modified (GM) organisms. In the method, genomic DNA extracted from an agricultural product is analyzed using various qualitative real-time PCR assays on a 96-well PCR plate, targeting for individual GM events, recombinant DNA (r-DNA) segments, taxon-specific DNAs, and donor organisms of the respective r-DNAs. In this article, we report the single-laboratory validation of both DNA extraction methods and component PCR assays constituting the real-time PCR array. We selected some DNA extraction methods for specified plant matrixes, i.e., maize flour, soybean flour, and ground canola seeds, then evaluated the DNA quantity, DNA fragmentation, and PCR inhibition of the resultant DNA extracts. For the component PCR assays, we evaluated the specificity and LOD. All DNA extraction methods and component PCR assays satisfied the criteria set on the basis of previous reports.
Influence of sample extraction solutions on the detection of wheat proteins by mass spectrometry
Authors: Heick Julia , Fischer Markus , Popping Bert 
Published: April 2012

Abstract
Routinely used methods for the detection of gluten mostly use denaturing agents and high salt concentrations to increase the extractability of the gluten fraction. These work well in combination with ELISA methods, but may have a negative effect on MS methods due to their influence on the ionization of the analyte leading to a significant reduction of signal intensities. A newly developed HPLC/MS/MS method was used to assess this influence. Four different extraction buffers were compared: 70% ethanol, TRIS-HCl, TRIS-HCl with dithiothreitol, and a commercially available cocktail solution. Unprocessed and processed wheat samples were analyzed. When analyzing unprocessed samples, a negative effect on ionization could be observed. Considering extraction capabilities and signal intensities, TRIS-HCl seemed to be the most suitable buffer in combination with the MS method. To assess whether the method was capable of detecting hidden wheat protein in different kinds of food, different food samples containing 0 to 34 000 μg/g gluten were analyzed using the TRIS-HCl extraction buffer.

AbstractThe optical manipulation of magnetism enabled by rare earth‐transition metal ferrimagnets holds the promise of ultrafast, energy‐efficient spintronic technologies. This work investigates laser‐induced picosecond spin currents generated by ferrimagnetic GdCo via terahertz emission spectroscopy. A suppression of the THz emission and spin current is observed at magnetization compensation when varying the temperature or alloy composition in the presence of a magnetic field. It is demonstrated that this is due to the formation of domains in the GdCo equilibrium magnetic configuration. Without an applied magnetic field, the picosecond spin current persists at the compensation point. The experimental findings support the model for THz spin current generation based on the transport of hot spin‐polarized electrons, which is dominated by the Co sublattice at room temperature. Only at low temperature a comparable contribution from Gd is detected but with slower dynamics. Finally, spectral analysis reveals a blueshift of the THz emission related to the formation of magnetic domains close to magnetization compensation.

AbstractPhotothermal catalytic dry reforming of methane (DRM) provides a sustainable carbon conversion route, but the syngas production rates remain unsatisfactory under low‐temperature conditions. This study reported a layered double hydroxide‐derived Ni–NiO heterojunction catalyst with optimized electronic environments via Ce doping. The Ce‐doped Ni–NiO catalyst exhibited excellent photothermal DRM performance, with H2 and CO production rates of 93.90 and 114.25 mmol g−1 min−1, respectively, and superior 12‐h stability. Mechanistic studies revealed that the Ni–NiO heterojunction activated CH4 and CO2 to form CHx* and O* species, while Ce doping promoted the coupling of these intermediates to CH3O*, enhancing syngas generation. This strategy effectively bonded the intermediate species generated from the reactants, thereby enhancing the conversion of CH4 and CO2 into syngas.

ABSTRACTIndividuals with Turner Syndrome (TS) can experience not only physical and medical differences but are also at risk for neurocognitive and associated psychosocial challenges. Specifically, research shows increased likelihood of difficulties with visual–spatial reasoning, executive functioning, attention, and mathematics skills. One emerging area of research focuses on deficits in social skills and increased prevalence of anxiety within this population. This review introduces relevant genetic influences of TS and examines existing research on social skills and anxiety in individuals with TS. The importance of collaboration between the medical team and school personnel for patients with TS is emphasized, and specific clinical recommendations, such as the use of the TS School Support Plan, are provided to facilitate this collaboration. This paper services as a brief introduction to orient the reader to considerations of strengthening collaboration between medical and school systems; however, future research is needed to investigate the effectiveness and acceptability of the School Support Plan to enhance liaison between the patient's medical and school teams.
