The passive solar heated school in Wallasey. VII. Window opening behaviour and the microclimate of a classroom

Previous work on factors which influence the opening or closing of windows suggests that at low ambient temperatures movement might be associated with odour levels, at intermediate temperatures, with ambient humidity and at higher ambient temperatures with the need to cool buildings. The data on window position, together with other physical measures during the period of observation in the Wallasey School, has been examined to see what quantity is most closely associated with window position. It appears that in the classroom the number of open windows depends mainly upon air temperature, but it also depends markedly on time of day.     

Pinpointing reality: How well can people judge true and mistaken emotional childhood memories?

The present study evaluated how well people are able to identify completely mistaken emotional memories from childhood. Further, possible individual differences, including personality/interpersonal traits and cue utilization strategies, contributing to this ability were examined. 137 participants (aged 17-34 yrs) viewed videos of true and mistaken childhood memory reports and judged whether the target had actually experienced the described event. Results indicate that 60% of judges accurately identified mistaken memories (greater than chance) and 53% accurately identified true memories (performing at chance). Compared to inaccurate judges, accurate judges were interpersonally less unassuming-ingenuous and more arrogant-calculating and aloof-introverted. Accurate judges also reported using more overall cues to formulate their judgments than inaccurate judges. Brief exposure to information about empirically based cues to mistaken memories prior to veracity judgments impaired rather than facilitated judgment ability. Implications for credibility assessment in applied settings and future research are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

2.5D Quantitative Millimeter Wave Imaging of a Hidden Object on a Simplified Human Body Model Using Value Picking Regularization

In this contribution, the authors provide a proof of principle for quantitative imaging of concealed objects on the human body using millimeter waves. A two-and-a-half-dimensional (2.5D) quantitative millimeter wave imaging algorithm is applied to reconstruct a hidden dielectric object on a clothed simplified human body model. At millimeter wave frequencies, the incident field is typically a fully three-dimensional (3D) Gaussian beam, illuminating only a limited spot on the body. Due to the large dimensions of the human body in terms of wavelengths, a 3D discretization is hardly feasible. Therefore, it is assumed that the electromagnetic properties of the body do not significantly change within the illuminated spot, along the longitudinal direction of a person. Hence, only the cross-section of a human body model is discretized. This 2.5D assumption however is still not sufficient to reduce the forward problem to a feasible size. Therefore, a priori knowledge on the illumination and on the scattering properties of the clothed human body is used to deduce a simplified model to describe the cross-section of the clothed human abdomen. The complex permittivity profile of a small dielectric object, hidden underneath clothing and representing some type of explosive, is reconstructed. The complex permittivity profiles of all other scatterers are assumed to be known. The presented quantitative inverse scattering algorithm is based on a Newton-type optimization, combined with an approximate line search and regularized by applying Stepwise Relaxed Value Picking regularization. The input data of the quantitative inverse scattering problem are synthetic scattering data since the authors are not aware of any amplitude and phase measurement data for concealed weapon detection yet made available to the inversion community at these high frequencies.     

Analysis of volatiles evolved during high-temperature treatment of thermally stable polymers. I. Nitrogen-containing acetylene-terminated resin

Cured samples of a nitrogen-containing acetylene-terminated resin, N,N′-(1,3-phenylene-dimethylidene)bis(3-ethynylaniline), have been heated at 10°C/min up to 900°C in a pyroprobe attached to a gas chromatograph/mass spectrometer (GC/MS). Analysis of the volatiles evolved during heating identified both gases and higher boiling compounds. The major higher boiling compounds are benzene, toluene, xylene, aniline, benzonitrile, m-methylaniline, and m-methylbenzonitrile; the gases include ammonia, methane, and traces of carbon dioxide. Correlations between sample temperature and the evolution of each of these compounds have been made. The onset of all volatile formation occurs between 450 and 500°C. The higher boiling volatiles peak, then end by approximately 700°C, while the gases peak then fall off but are still being evolved at 900°C. Average weight loss measurements of 13.6% at 700°C and 15.7% at 900°C agree with previously published thermogravimetric analysis (TGA) data. © 1993 John Wiley & Sons, Inc.     

Pectic Galactan Polysaccharide-Based Gene Delivery System for Targeting Neuroinflammation

Treating neuroinflammation-related injuries and disorders through manipulation of neuroinflammation functions is being heralded as a new therapeutic strategy. In this study, a novel pectic galactan (PG) polysaccharide based gene therapy approach is developed for targeting reactive gliosis in neuroinflammation. Galectin-3 (Gal-3) is a cell protein with a high affinity to β-galactoside sugars and is highly expressed in reactive gliosis. Since PG carries galactans, it can target reactive gliosis via specific carbohydrate interaction between galactan and Gal-3 on the cell membrane, and therefore can be utilized as a carrier for delivering genes to these cells. The carrier is synthesized by modifying quaternary ammonium groups on the PG. The resulting quaternized PG (QPG) is found to form complexes with plasmid DNA with a mean diameter of 100 nm and have the characteristics required for targeted gene therapy. The complexes efficiently condense large amounts of plasmid per particle and successfully bind to Gal-3. The in vivo study shows that the complexes are biocompatible and safe for administration and can selectively transfect reactive glial cells of an induced cortical lesion. The results confirm that this PG-based delivery system is a promising platform for targeting Gal-3 overexpressing neuroinflammation cells for treating neuroinflammation-related injuries and neurodegenerative diseases.     

Comparison of anxiety management training and self-control desensitization.

Compared the effects of anxiety management training (AMT) and self-control desensitization (SCD) in reducing targeted (test anxiety) and nontargeted anxieties. Comparisons revealed that AMT and SCD effectively reduced state (worry, emotionality, and state test anxiety) and trait (Debilitating scale of Alpert-Haber Achievement Anxiety Test and test items from the Fear Inventory) debilitating test anxiety and increased facilitating text anxiety (Facilitating scale of the Achievement Anxiety Test) relative to controls. A 6-wk follow-up demonstrated maintenance of debilitating test anxiety reduction. No performance differences were found in analog testing, but Ss receiving treatment had significantly higher psychology grades than those not receiving treatment. Posttreatment findings reveal some nontargeted anxiety reduction for SCD; however, by follow-up both treatments evidenced significant nontargeted anxiety reduction. The results are discussed in terms of remedial and preventive functions met by the self-control interventions; the possibility of treating diverse anxieties within a single AMT group is also considered.
