Processing—Morphology regulation of epoxy/layered‐silicate nanocomposites
Authors: Chen Chenggang , Benson‐Tolle Tia , Baur Jeffery W. , Putthanarat Sirina 
Published: March 2008

AbstractPolymer/layered‐silicate nanocomposites have unique and hierarchical structures that can provide improvements to the properties of polymeric materials. Controlling the dispersion of the nanomaterials through processing greatly influences the resulting morphology and the resulting properties of the nanocomposite. In this article, the dispersion behavior of organic layered silicates (OLS) as a function of the processing procedure is reported. The behavior of the OLS in all stages of processing—in the solvent, the epoxy prepolymer, and in the epoxy through cure—is discussed. On the basis of understanding of the dispersion behavior of the OLS in the epoxy resin at each stage of processing, a different processing procedure can be designed and used so that the morphology of the epoxy/layered‐silicate nanocomposite can be regulated. Mild low‐shear processing resulted in an intercalated nanocomposite with large‐size aggregates (> 10 μm), and high‐shear processing resulted in an intercalated nanocomposite with relatively small‐size aggregates (0.5–3 μm), whereas the high‐shear and ultrasonication processing procedures gave rise to an exfoliated nanocomposite. © 2008 Wiley Periodicals, Inc.

Published: March 2008

AbstractThe melting and crystallization behaviors of poly(trimethylene terephthalate) (PTT)/acrylonitrile–butadiene–styrene (ABS) blends were investigated with and without epoxy or styrene–butadiene–maleic anhydride copolymer (SBM) as a reactive compatibilizer. The existence of two separate composition‐dependent glass‐transition temperatures (Tg's) indicated that PTT was partially miscible with ABS over the entire composition range. The melting temperature of the PTT phase in the blends was also composition dependent and shifted to lower temperatures with increasing ABS content. Both the cold crystallization temperature and Tg of the PTT phase moved to higher temperatures in the presence of compatibilizers, which indicated their compatibilization effects on the blends. A crystallization exotherm of the PTT phase was noticed for all of the PTT/ABS blends. The crystallization behaviors were completely different at low and high ABS contents. When ABS was 0–50 wt %, the crystallization process of PTT shifted slightly to higher temperatures as the ABS content was increased. When ABS was 60 wt % or greater, PTT showed fractionated crystallization. The effects of both the epoxy and SBM compatibilizers on the crystallization of PTT were content dependent. At a lower contents of 1–3 wt % epoxy or 1 wt % SBM, the crystallization was retarded, whereas at a higher content of 5 wt %, the crystallization was accelerated. The crystallization kinetics were analyzed with a modified Avrami equation. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
Distribution modelling to guide stream fish conservation: an example using the mountain sucker in the Black Hills National Forest, USA
Authors: Dauwalter Daniel C. , Rahel Frank J. 
Published: March 2008

Abstract
Conservation biologists need tools that can utilize existing data to identify areas with the appropriate habitat for species of conservation concern. Regression models that predict suitable habitat from geospatial data are such a tool. Multiple logistic regression models developed from existing geospatial data were used to identify large‐scale stream characteristics associated with the occurrence of mountain suckers (Catostomus platyrhynchus), a species of conservation concern, in the Black Hills National Forest, South Dakota and Wyoming, USA.
Stream permanence, stream slope, stream order, and elevation interacted in complex ways to influence the occurrence of mountain suckers. Mountain suckers were more likely to be present in perennial streams, and in larger, higher gradient streams at higher elevations but in smaller, lower gradient streams at lower elevations.
Applying the logistic regression model to all streams provided a way to identify streams in the Black Hills National Forest most likely to have mountain suckers present. These types of models and predictions can be used to prioritize areas that should be surveyed to locate additional populations, identify stream segments within catchments for population monitoring, aid managers in assessing whether proposed forest management will potentially have impacts on fish populations, and identify streams most suitable for stream rehabilitation and conservation or translocation efforts.
When the effect of large brown trout (Salmo trutta) was added to the best model of abiotic factors, it had a negative effect on the occurrence of mountain suckers. Negative effects of brown trout on the mountain sucker suggest that management of recreational trout fisheries needs to be balanced with mountain sucker conservation in the Black Hills. However, more spatially explicit information on brown trout abundance would allow managers to understand where the two species interact and where recreational fisheries need to be balanced with fish conservation.

Controlled user evaluations of information visualization interfaces for text retrieval: Literature review and meta‐analysis
Authors: Julien Charles‐Antoine , Leide John E. , Bouthillier France 
Published: March 2008

AbstractThis review describes experimental designs (users, search tasks, measures, etc.) used by 31 controlled user studies of information visualization (IV) tools for textual information retrieval (IR) and a meta‐analysis of the reported statistical effects. Comparable experimental designs allow research designers to compare their results with other reports, and support the development of experimentally verified design guidelines concerning which IV techniques are better suited to which types of IR tasks. The studies generally use a within‐subject design with 15 or more undergraduate students performing browsing to known‐item tasks on sets of at least 1,000 full‐text articles or Web pages on topics of general interest/news. Results of the meta‐analysis (N= 8) showed no significant effects of the IV tool as compared with a text‐only equivalent, but the set shows great variability suggesting an inadequate basis of comparison. Experimental design recommendations are provided which would support comparison of existing IV tools for IR usability testing.
The effects of culture conditions on the glycosylation of secreted human placental alkaline phosphatase produced in Chinese hamster ovary cells

Published: March 2008

AbstractThe effects of different culture conditions, suspension and microcarrier culture and temperature reduction on the structures of N‐linked glycans attached to secreted human placental alkaline phosphatase (SEAP) were investigated for CHO cells grown in a controlled bioreactor. Both mass spectrometry and anion‐exchange chromatography were used to probe the N‐linked glycan structures and distribution. Complex‐type glycans were the dominant structures with small amounts of high mannose glycans observed in suspension and reduced temperature cultures. Biantennary glycans were the most common structures detected by mass spectrometry, but triantennary and tetraantennary forms were also detected. The amount of sialic acid present was relatively low, approximately 0.4 mol sialic acid/mol SEAP for suspension cultures. Microcarrier cultures exhibited a decrease in productivity compared with suspension culture due to a decrease in both maximum viable cell density (15–20%) and specific productivity (30–50%). In contrast, a biphasic suspension culture in which the temperature was reduced at the beginning of the stationary phase from 37 to 33°C, showed a 7% increase in maximum viable cell density, a 62% increase in integrated viable cell density, and a 133% increase in specific productivity, leading to greater than threefold increase in total productivity. Both microcarrier and reduced temperature cultures showed increased sialylation and decreased fucosylation when compared to suspension culture. Our results highlight the importance of glycoform analysis after process modification as even subtle changes (e.g., changing from one microcarrier to another) may affect glycan distributions.

An investigation of small‐molecule surfactants to potentially replace pluronic F‐68 for reducing bubble‐associated cell damage
Authors: Hu Weiwei , Rathman James J. , Chalmers Jeffrey J. 
Published: March 2008

AbstractIt is well known that bubble rupture has a detrimental effect on mammalian cells. As a result, Pluronic F‐68 (PF‐68), a nonionic surfactant, is commonly used to reduce bubble‐associated cell damage in sparged bioreactors. While PF‐68 is currently effective, there is a concern with respect to its decrease in effectiveness as cell concentrations increase (Ma et al., 2004, Biotechnol Prog 20:1183–1191). In addition, having more than one effective surfactant for cell culture is also highly desirable. Given the empirical nature in which PF‐68 was initially discovered as a cell culture additive, a structure‐performance study of small molecule surfactants, a distinct group which have been previously investigated for other purposes, was performed in an attempt to find a replacement for PF‐68. In this study, a generic platform was established to initially screen both the type and concentration of these surfactants for cytotoxicity. Promising candidates where then evaluated for their ability to rapidly lower the surface tension (dynamic surface tension) of culture media and their ability to prevent cell‐bubble attachment in a specially developed bubble creation and collection system. Several promising small‐ molecule surfactants, and their effective concentration, were identified, which can reduce cell‐bubble attachment efficiently without being harmful to cells. Biotechnol.
