Performance results of running parallel applications on the InteGrade
Authors: Cáceres E. N. , Mongelli H. , Loureiro L. , Nishibe C. , Song S. W. 
Published: October 2009

AbstractThe InteGrade middleware intends to exploit the idle time of computing resources in computer laboratories. In this work we investigate the performance of running parallel applications with communication among processors on the InteGrade grid. As costly communication on a grid can be prohibitive, we explore the so‐called systolic or wavefront paradigm to design the parallel algorithms in which no global communication is used. To evaluate the InteGrade middleware we considered three parallel algorithms that solve the matrix chain product problem, the 0–1 Knapsack Problem, and the local sequence alignment problem, respectively. We show that these three applications running under the InteGrade middleware and MPI take slightly more time than the same applications running on a cluster with only LAM‐MPI support. The results can be considered promising and the time difference between the two is not substantial. The overhead of the InteGrade middleware is acceptable, in view of the benefits obtained to facilitate the use of grid computing by the user. These benefits include job submission, checkpointing, security, job migration, etc. Copyright © 2009 John Wiley & Sons, Ltd.
Ionic Liquids in Refinery Desulfurization: Comparison between Biphasic and Supported Ionic Liquid Phase Suspension Processes
Authors: Kuhlmann Esther , Haumann Marco , Jess Andreas , Seeberger Andreas , Wasserscheid Peter 
Published: October 2009

AbstractThe desulfurization of fuel compounds in the presence of ionic liquids is reported. For this purpose, the desulfurization efficiency of a variety of imidazolium phosphate ionic liquids has been tested. Dibenzothiophene/dodecane and butylmercaptan/decane mixtures were used as model systems. Single‐stage extractions reduced the sulfur content from 500 ppm to 200 ppm. In multistage extractions the sulfur content could be lowered to less than 10 ppm within seven stages. Regeneration of the ionic liquid was achieved by distillation or re‐extraction procedures. Supported ionic liquid phase (SILP) materials, obtained by dispersing the ionic liquid as a thin film on highly porous silica, exhibited a significantly higher extraction performance owing to their larger surface areas, reducing the sulfur content to less than 100 ppm in one stage. Multistage extraction with these SILP materials reduced the sulfur level to 50 ppm in the second stage. The SILP technology offers very efficient utilization of ionic liquids and circumvents mass transport limitations because of the small film thickness and large surface area, and allows application of the simple packed‐bed column extraction technique.
Analysis of PEG‐fractionated high‐molecular‐mass proteins in human plasma by non‐denaturing micro 2‐DE and MALDI‐MS PMF
Authors: Jin Ya , Manabe Takashi 
Published: October 2009

AbstractThe process of 0–4% PEG precipitation of high‐molecular‐mass proteins (around and above 1×103 kDa) in human plasma was analyzed by non‐denaturing micro 2‐DE employing agarose IEF gels in the first dimension, and by MALDI‐MS PMF. The PEG 0–2% precipitate could be mostly re‐dissolved (fraction PS2%), but some part remained as precipitate (fraction PP2%). Non‐denaturing 2‐DE followed by MALDI‐MS PMF showed that PS2% contained fibrinogen (Fb), fibronectin (FN), and their oligomers as the major components, and von Willebrand factor and coagulation factor XIII as the minor components. PP2% was directly subjected to MALDI‐MS PMF and FN and Fb were assigned, suggesting it was formed by co‐precipitation of the two proteins. The PEG 2–4% precipitate could be totally dissolved, but after freezing and thawing the solution, a small amount of precipitate appeared. MALDI‐MS PMF analysis of the precipitate (PP4%) suggested that its major constituent is complement C1. The soluble fraction of the PEG 2–4% precipitate (PS4%), analyzed by non‐denaturing 2‐DE and MALDI‐MS PMF, contained C4b‐binding protein and its complex with complement C4, low‐density lipoproteins, IgM, and complement C1 subcomponent q, together with Fb, FN, and their oligomers. When the PS4% fraction was analyzed by a Type‐II 2‐DE technique (non‐denaturing IEF followed by SDS‐PAGE, no reducing agent being used), several proteins in molecular mass range from 7×101 to 2×102 kDa appeared, suggesting that these proteins interacted with the high‐molecular‐mass proteins, then dissociated in the presence of SDS.
Late Tournaisian (Carboniferous) brachiopods from Mouydir (Central Sahara, Algeria)
Authors: Mottequin Bernard , Legrand‐Blain Marie 
Published: October 2009

AbstractA small‐sized brachiopod fauna, representing an orthid, rhynchonellid and spiriferid community which lived in a low‐energy environment, is reported from the lower part of the Argiles de Teguentour and was collected around Oued Tamertasset (or Temertasset) and Oued Habadra in north‐western Mouydir (Algerian Sahara). Associated goniatites indicate an early Late Tournaisian age (Pericyclus–Progoniatites assemblage). Thirteen brachiopod species belonging to 12 genera and 5 orders (Productida, Orthida, Rhynchonellida, Athyridida and Spiriferida) are described. Mouydirhynchus is proposed as a new rhynchonellid genus and the species Rhipidomella prolifica, Mouydirhynchus quietus and Eomartiniopsis mouydirensis are new. The other described taxa are the following: Chonetipustula? sp., strophalosioid gen. et sp. indet., Schizophoria sp., trigonirhynchiid gen. indet. sp. A, trigonirhynchiid gen. indet. sp. B, Hemiplethorhynchus? sp., Coveenia? sp., Crurithyris cf. fissa, Punctothyris? sp., and elythid gen. et sp. indet. Copyright © 2009 John Wiley & Sons, Ltd.
Hydrothermal alteration of plagioclase in granitic rocks from Proterozoic basement of SE Sweden
Authors: Morad S. , El‐Ghali M. A. K. , Caja M. A. , Sirat M. , Al‐Ramadan K. , Mansurbeg H. 
Published: October 2009

AbstractPetrographic examinations and electron microprobe analyses of Proterozoic granitic rocks, SE Sweden aimed to characterize and unravel the mechanisms and conditions of plagioclase alterations. These alterations include saussuritization, albitization and replacement of plagioclase by K‐feldspar. The hydrothermal alterations, which are inferred to have occurred at ca. 250–400°C, resulted in concomitant formation of Al‐rich titanite, epidote, calcite, pumpellyite, prehnite and iron oxides. Replacement of plagioclase by K‐feldspar occurs in red‐stained zones, which have developed close to thin fractures owing to the precipitation of tiny Fe‐oxide pigment particles within the altered plagioclase, whereas saussuritized plagioclase has less systematic spatial relationships to these fractures. Albitization of plagioclase occurred in rocks that are poor in biotite compared to rocks that suffered extensive saussuritization. The chemical and textural characterization of various types of plagioclase alterations allows elucidation of the granitic hydrothermal systems. Features of feldspar alteration in the granitic rocks are similar to those encountered in feldspathic sandstones and should hence be considered in studies on diagenetic changes of siliciclastic successions during basin evolution.

Palynological evidence for Pennsylvanian (Late Carboniferous) vegetation change in the Sydney Coalfield, eastern Canada
Authors: Dimitrova Tatyana K. , Zodrow Erwin L. , Cleal Christopher J. , Thomas Barry A. 
Published: October 2009

AbstractThe palynology of clastic samples from seven stratigraphical levels in the late Moscovian Sydney Mines Formation, exposed along the shore at Bras d'Or, Nova Scotia, has been investigated. Most of the samples were from roof shales of major coals; the one sample that was not yielded a much higher proportion of pollen derived from extra‐basinal vegetation. The four stratigraphically lower roof shale samples yielded essentially similar palynological spectra, with 39 ± 4% lycophytes, 9 ± 4% sphenophylls, 23 ± 4% tree‐ferns, 12 ± 4% other ferns and 5 ± 3% cordaites. The palynology of the upper part of the investigated succession suggests a shift in vegetation towards one favouring more marattialean tree‐ferns, cordaites and conifers, and fewer lycophytes. This correlates with changes in drainage patterns as the alluvial plain migrated seawards and thus changed water tables. No evidence was found to suggest significant climate change at this time.

Polyethylene wear debris produced in a knee simulator model: Effect of crosslinking and counterface material
Authors: Williams Paul A. , Brown Cindy M. , Tsukamoto Riichro , Clarke Ian C. 
Published: October 2009

AbstractPolyethylene (PE) debris has been well studied in clinical retrievals and laboratory wear simulations of total hip replacements. However, little is known about PE debris from total knee replacements. In this study, we investigated the effects of crosslinking PE bearings and alternate counterface material. Mildly (35 kGy) and highly (70 kGy) crosslinked PE were studied in combination with CoCr and zirconia femoral counterfaces. Wear debris was isolated and its morphology characterized. Except for changes in PE debris size with the zirconia bearings, there were no morphological changes greater than 10%. The average submicron volume fraction decreased from about 65% to 45% with both increased crosslinking and changing counterface material from CoCr to zirconia. The averaged number of generated particles decreased by ∼fourfold with increased crosslinking and threefold with changing counterface material from CoCr to zirconia. This showed that the degree of PE crosslinking and the choice of counterface material were important factors in the PE wear debris production in total knee simulator replacements. © 2009 Wiley Periodicals, Inc.

Toxicity evaluation of biodegradable and thermosensitive PEG‐PCL‐PEG hydrogel as a potential in situ sustained ophthalmic drug delivery system
Authors: Yin HongBo , Gong ChangYang , Shi Shuai , Liu XuYang , Wei YuQuan , Qian ZhiYong 
Published: October 2009

AbstractIn this work, a biodegradable poly(ethylene glycol)‐poly(ε‐caprolactone)‐poly (ethylene glycol) (PEG‐PCL‐PEG, PECE) triblock copolymer was successfully synthesized, which was flowing sol at low temperature and turned to nonflowing gel at body temperature. The toxicity evaluation of PECE hydrogel as a potential in situ sustained opthalmic drug delivery system was performed, including the biodegradability of PECE hydrogel in the eye, its effect on cultured human lens epithelia, intraocular pressure, and ocular tissues. The results indicated that the prepared PECE hydrogel was biocompatible and biodegradable despite of temporary elevated intraocular pressure and slight corneal endothelial damage at specific concentration. Therefore, PECE hydrogel may be a safe candidate for sustained ophthalmic drug delivery system. © 2009 Wiley Periodicals, Inc. J Biomed Mater Res Part B: Appl Biomater 2010
