Color characteristics of costumes for Korean folk festivals and color consciousness of Koreans
Authors: Kim Ji Young 
Published: June 2010

AbstractThe purpose of this study was to identify the color characteristics of Korean culture, the color consciousness of Korean people based on their arche‐pattern sentiment, and to analyze the colors of the costumes of Korean folk festivals, which clearly suggest the archetype of Korean tradition. The range of this study is focused on Korea's important intangible cultural assets in which the colors used in folk festivals were fully expressed, and 20 folk games and plays were selected from among different festival events. Hundred and fifteen pictures from these 20 folk games/plays were used to extract the costume colors and conduct color analyses. Among 647 colors extracted in total, this article used 199 colors after excluding overlapping colors. The results show that Korean folk festivals have served as the medium of nondifferentiation that goes beyond the differentiated order of reality. Costumes for these Korean folk festivals, such as folk games and folk plays, have a sacred meaning as ritualistic robes. Five element colors in these costumes for the Korean folk festival are used as a means of circulatory thinking and as a symbol of Chaos—the very origin of undifferentiated thinking—beyond one's daily lives. It was found that these highly chromatic five element colors have always been used, wherever this undifferentiated thinking was strongly expressed. Delivering visually strong impacts, these five element colors symbolize the concept of the Arche‐pattern theory, being related to infinite freedom without any restrictions. © 2010 Wiley Periodicals, Inc.

Molecular Wires in Single‐Molecule Junctions: Charge Transport and Vibrational Excitations
Authors: Ballmann Stefan , Hieringer Wolfgang , Secker Daniel , Zheng Qinglin , Gladysz John A. , Görling Andreas , Weber Heiko B. 
Published: June 2010

AbstractWe investigate the effect of vibrations on the electronic transport through single‐molecule junctions, using the mechanically controlled break junction technique. The molecules under investigation are oligoyne chains with appropriate end groups, which represent both an ideally linear electrical wire and an ideal molecular vibrating string. Vibronic features can be detected as satellites to the electronic transitions, which are assigned to longitudinal modes of the string by comparison with density functional theory data.

Published: June 2010

AbstractBackground:The process of maturation of the immune system leads to generation of various lymphoid cell populations having the ability to react in specific way and expressing various markers on the cell surface. The study was set up to establish reference values for B lymphocyte subpopulations in peripheral blood of children and young adults to find the spectrum of their physiological age‐related variation.Methods:Blood samples were taken from 292 children and young adults aged 0–31 years and tested for distribution of B cell subsets. Relative and absolute sizes of non‐memory and memory, transitional, naïve, immature marginal zone‐like/IgM‐only memory, class‐switched memory, double negative, activated, and plasmacytoid cell populations were determined by four‐color flow cytometry, based on differential expression of CD19, IgM, IgD, CD21, CD27, and CD38. Significant variation both in relative, as well as in absolute numbers of individual cell populations in tested groups was observed.Results:The reference values for age‐related B cell subsets in eleven age groups, established as result of this study, may be used in diagnostics of any pathology related to B cell maturation process, as well as in attempts of correlating laboratory results with clinical symptoms of many defects affecting antibody production in pediatric population.Conclusion:Determination of B cell subpopulations carried in patients with antibody deficiencies may help to understand the nature of the disease and prevent its complications. © 2010 International Clinical Cytometry Society
A low‐complexity adaptive receiver for DS‐CDMA systems in unknown code delay environment
Authors: Chen Jun‐Da , Ueng Fang‐Biau , Lin Pi‐Feng 
Published: June 2010

AbstractIn direct‐sequence code division multiple access (DS/CDMA) multiuser communication systems in multipath channels, both intersymbol interference (ISI) and multiple‐access interference (MAI) must be considered. The multipath channel characterizes the propagation effects including the timing offset and delays, etc. Traditionally, we use the delay‐locked loop (DLL) code tracking loop to recover the timing delay. But DLL cannot work well in multipath environment. In this paper, we propose a low‐complexity adaptive receiver to suppress ISI/MAI and solve the timing offset problems without using conventional DLL code tracking loop. The proposed receiver employs an adaptive filter whose weights are adapted using a block least‐mean square error algorithm with fractional sampling. Simulations confirm the good performance, including learning curves and theoretical analysis of minimum mean‐square error, of the proposed receiver. Copyright © 2010 John Wiley & Sons, Ltd.

In silico subtraction approach reveals a close lineage relationship between follicular dendritic cells and BP3hi stromal cells isolated from SCID mice
Authors: Wilke Gordon , Steinhauser Gudrun , Grün Joachim , Berek Claudia 
Published: June 2010

AbstractOrganization of the stromal compartments in secondary lymphoid tissue is a prerequisite for an efficient immune reaction. In particular, follicular dendritic cells (FDC) are pivotal for the activation and differentiation of B cells. To investigate the development of FDC, FDC together with tightly associated B cells (FDC networks) were micro‐dissected from frozen tissue sections and follicular B cells were sorted by FACS. Using an in silico subtraction approach, gene expression of FDC was determined and compared with that of follicular stromal cells micro‐dissected from the spleen of SCID mice. Nearly 90% of the FDC genes were expressed in follicular stromal cells of the SCID mouse, providing further evidence that FDC develop from the residual network of reticular cells. Thus, it suggests that rather minor modifications in the gene expression profile are sufficient for differentiation into mature FDC. The analysis of different immune‐deficient mouse strains shows that a complex pattern of gene regulation controls the development of residual stromal cells into mature FDC. The in silico subtraction approach provides a molecular framework within which to determine the diverse roles of FDC in support of B cells and to investigate the differentiation of FDC from their mesenchymal precursor cells.
Basophils are potent antigen‐presenting cells that selectively induce Th2 cells
Authors: Nakanishi Kenji 
Published: June 2010

AbstractBasophils and mast cells are important effector cells in helminth‐infected host and IgE‐mediated allergic inflammation. Although they have the same progenitors, basophils and mast cells complete their terminal differentiation in the bone marrow and peripheral tissues, respectively, and only basophils circulate in the blood. Although it is recognized that basophils are important for Th2 responses, and it is also well established that IL‐4 is required for Th2 differentiation from naïve CD4+ T cells, the nature of the cells that produce “early” IL‐4, remained elusive until recently. Three groups independently demonstrated that basophils are the predominant APC in inducing Th2 response against helminth parasites and allergens. Basophils express MHC class II and CD80/86, have the potential to take‐up and process protein Ag (particularly Ag–IgE complex) and to present peptide in the context of MHC class II, and to produce IL‐4. These Ag‐pulsed basophils induce the development of Th2 cells both in vitro and in vivo. Thus, basophils contribute to Th2/IgE response by the production of IL‐4 and presentation of MHC class II/peptide complex to naïve CD4+ T cells, in contrast to the Th1‐inducing action of DC. In this review, we summarize what is known regarding basophil function in allergy and parasite infection, examine the novel Ag‐presenting function of basophils and discuss potential clinical implications of this finding.
Tumor immune therapy: Lessons from infection and implications for cancer – Can IL‐7 help overcome immune inhibitory networks?
Authors: Pellegrini Marc , Mak Tak W. 
Published: June 2010

AbstractThe complexity that the immune system faces in distinguishing pathogens from self is manifested by the intricate immunological networks involved in initiation, promotion and abrogation of immunity. A substantially more complex algorithm is required to distinguish normal from aberrant self (e.g. in the form of cancers), and this is reflected by the apparent inefficiency of our immune system to eradicate tumors; however, with our expanding insights into the molecular networks that govern immunity, we can now consider therapies that transiently promote immunity and/or antagonize immune inhibitory networks. Cytokines that normally function to regulate immune responses hold much therapeutic promise in this regard. Translating this promise to tangible outcomes will require a thorough analysis of how, when and in what way these cytokines should be used to take advantage of synergistic and complementary effects of current cancer therapeutics. In this review, we focus on IL‐7, as much data are emerging on the ability of this unique homeostatic cytokine to augment various anti‐tumor immunotherapeutic modalities.

AbstractA series of novel chromium complexes that bear anilido–imine ligands, [{ortho‐C6H4(NAr′)(CH=NAr″)}CrCl2(thf)2] [Ar′ = Ar″ = C6H5 (1); Ar′ = Ar″ = p‐MeC6H4 (2); Ar′ = Ar″ = 2,6‐Me2C6H3 (3); Ar′ = 2,6‐iPr2C6H3, Ar″ = 2,6‐Me2C6H3 (4); Ar′ = Ar″ = 2,6‐iPr2C6H3 (5)], have been synthesized and characterized by elemental analysis, IR spectroscopy, and ESI‐MS. The molecular structures of complexes 1 and 2 have been confirmed by single‐crystal X‐ray diffraction analysis. When activated with methylaluminoxane (MAO), these complexes exhibit reasonable to good catalytic activity for ethylene polymerization and produce polyethylene with moderate molecular weights.

AbstractTwo approaches based on the ring‐closing metathesis reaction have been explored for the synthesis of the core structure of the marine natural products, the aurisides. The second approach, accomplished in a stereocontrolled manner, used both a Brown's allylation and an Evans' aldolisation, and finally a transannular ketalization to deliver a highly functionalized auriside analogue.
A Calibration Strategy for Stripping Voltammetry of Lead on Silver Electrodes
Authors: Jakubowska Małgorzata , Baś Bogusław , Ciepiela Filip , Kubiak Władysław W. 
Published: June 2010

AbstractThis work presents a calibration strategy for stripping voltammetry which enables improving and testing accuracy, using as an example quantitative determination of lead ions on a silver electrode. The proposed procedure integrates the interpolative and extrapolative conventional calibration methods. In the proposed approach the accuracy of determination is verified by the evaluation of the statistical agreement of the results obtained in standard addition and a series of standard methodologies. In the experiments only the standard solutions used to perform quantification are required. The application of procedures of baseline subtraction may decrease the value of systematic error, therefore such an algorithm constitutes an essential part of the described methodology and has been given in detail. The proposed calibration strategy has been tested for the determination of Pb(II) ions in certified reference material (CRM) water samples.
Volatile emissions from hot bitumen storage tanks
Authors: Deygout François 
Published: June 2010

AbstractThe purpose of this study is to estimate the fugitive volatile organic compounds (VOCs) emitted from hot stored bitumen and to assess the contribution of these VOCs on the overall emissions in refinery processes. All the usual information regarding VOC emissions from tank storage is based on the storage of petroleum products at ambient temperature (mainly volatile streams such as fuels), and all the calculation systems used to predict or estimate the emissions are based on daily or seasonal temperature variations. Consequently, a dedicated protocol for hot bitumen storage using measurement‐based estimations was established. Tank headspace compositions were also determined. Some annual emissions were estimated and comparisons were made with current emission factor‐based methods.The atmospheric VOC emissions from hot stored bitumen were shown to be made of residual petroleum compounds. The experiments demonstrated that volatile emissions are more bitumen related than temperature dependent in the studied temperature range. The experiments also showed VOC depletion over time. Storage duration is the predominant factor affecting VOC emission levels. Another main outcome concerns the influence of differences in the manufacturing process between oxidized and nonoxidized bitumens, with the blowing operation decreasing the VOC contents by stripping. Finally, it is shown that hot bitumen storage tanks make a low contribution to the overall fugitive VOC emissions in a refinery process. © 2010 American Institute of Chemical Engineers Environ Prog, 2011
Metal uptake from aqueous leachate of poultry litter by natural zeolite
Authors: Turan N. Gamze 
Published: June 2010

AbstractThe objective of this research was to identify Cu (II) and Zn (II) ions in the litter aqueous leachate and to take up these metals from leachate using natural zeolite. The adsorption capacities and sorption efficiencies were determined. The sorption efficiencies increased with increasing natural zeolite ratio. The pseudo first‐order, the pseudo second‐order, Elovich, and the intraparticle diffusion kinetic models were used to describe the kinetic data to estimate the rate constants. The second‐order model best described adsorption kinetic data. The results indicated that natural zeolite showed excellent adsorptive characteristics for the removal of Cu (II) and Zn (II) from aqueous leachate of poultry litter and could be used as additive materials for poultry litter due to its high uptake capacity and the abundance in availability. © 2010 American Institute of Chemical Engineers Environ Prog, 2011
Effects of aquatic and terrestrial carbaryl exposure on feeding ability, growth, and survival of American toads
Authors: Webber Nicholas R. , Boone Michelle D. , Distel Christopher A. 
Published: June 2010

Abstract
The present study evaluates whether larval density and aquatic exposure to the insecticide carbaryl influenced susceptibility to terrestrial exposure of carbaryl through effects on juvenile feeding ability, growth, and survival with metamorphs of American toads (Bufo americanus). Tadpoles were reared in outdoor mesocosms, and individuals were brought into the lab at metamorphosis for terrestrial exposure studies. The present study indicated that feeding and survival of toads after metamorphosis was not affected by earlier aquatic or subsequent terrestrial exposure; therefore, the impacts of short-lived insecticides may be most significant to aquatic, larval stages.

Studies on the sorption behaviors of phenanthrene on marine sediments
Authors: Yang Gui-Peng , Zheng Xuan 
Published: June 2010

AbstractIn the present study, the sorption behaviors of phenanthrene on marine sediments were investigated. Through the study of the adsorption kinetics and isotherms, the adsorption mechanism of phenanthrene on marine sediments was described. The results showed that the adsorption kinetics of phenanthrene on marine sediments could be described by the second-order kinetic equation. The sorption rate of phenanthrene was very rapid, and the equilibrium time was slightly longer in deionized water than in natural seawater. The adsorption isotherms of phenanthrene on all the sediments could be very well described by Freundlich equations. The adsorption capacity of phenanthrene had a significant positive correlation with the sediment organic carbon content. Some external factors that could affect adsorption behaviors of phenanthrene were also investigated. Results of the present study showed that the adsorption capacity of phenanthrene on the sediment decreased with increasing temperature. Moreover, the adsorption amounts of phenanthrene on the sediment appeared to be lower in natural seawater than in deionized water. Finally, the presence of the surfactant of Tween20 in the system could enhance the adsorption of phenanthrene on the sediment, and the adsorbance was proportional to the concentration of Tween20.

Authors: Santolo Gary M. , Yamamoto Julie T. , Neiberg Pamela S. , Wilson Barry W. 
Published: June 2010

Abstract
The accumulation of selenium in Coturnix quail, a sensitive species to selenium toxicity, was studied. Quail were fed diets containing 0.7 µg/g (control), 12 µg/g (low-Se), and 22 µg/g (high-Se) as seleno-L-methionine for four weeks. At the end of the four weeks, blood selenium in the treatment groups had a positive significant relationship to diet, and selenium in blood was approximately two times, and in livers was approximately three times, the dietary concentration. Quail in the low-Se group accumulated selenium to higher levels over the same time period than American kestrels and mallards fed selenomethionine at similar concentrations in other studies. Food consumption was similar among the groups throughout the study. Body mass, as a percent of initial body mass, was similar in the control and low-Se groups (102%) but lower in the high-Se group (97%). Liver mass, as a percent of initial body mass, showed a positive dose-dependent response to dietary selenium, and liver mass was significantly higher in quail fed 22 µg Se/g than in control quail. Unlike other species studied, accumulation of selenium in blood did not plateau but continued to increase until the study ended. Environ. Toxicol. Chem. 2010;29:2220–2224. © 2010 SETAC
