A narratív self emlékezeti tükörben
Authors: Papp Orsolya , Marno Hanna , Kónya Anikó 
Published: March 2005

A tanulmány azt a kérdést járja körül, hogy élettörténeti szövegekben mennyiben jelenik meg az elbeszélő selfkoherenciája. Bizonyos emlékezeti és narratív koherenciamutatók feltételezhetően szoros kapcsolatban állnak a selfkoherenciával, így a kérdésre segítenek választ adni. Kiindulásunk alapját Fitzgerald (1992, 1996) selfnarratív elmélete képezi, amelyet a reminiszcenciahatás értelmezésére dolgozott ki. Ez az elmélet a személyes integráltságot a felidézett eseményeknek az élettörténeti időben való eloszlási mintázatában keresi. Fitzgerald (1992) eljárását követő, 25 idős személlyel végzett vizsgálatunkban a reminiszcenciagörbe (vagyis az adott életkori szakaszra vonatkozó emlékek relatív gyakoriságának eloszlása) egyértelműen mutatja a reminiszcenciahatást: az emlékek száma 16 és 20 éves kor között tendenciaszerűen emelkedik, majd 21 és 30 éves kor között éri el maximumát, végül a 31-35 éves életkori szakaszban radikálisan csökken. Az elemzés következő lépcsőjében a narratív koherencia megállapítására K. J. Gergen és M. M. Gergen (1988) jól formáltsági kritériumrendszerét alkalmaztuk. Ennek a mutatónak a használata leszűkíti a reminiszcenciahatás tartományát 21 és 25 év közé. Eredményünk a selfnarratív hipotézis kiegészítéseként értelmezhető: 1. azok a személyek, akik a leginkább jól formált, koherens történeteket idézik fel, elsősorban ebből a szűkebb reminiszcenciacsúcsból választják jelentős életeseményeiket; 2. a jól formált csoporttal szemben a kevésbé jól formált eseményeket elbeszélő személyek egyáltalán nem mutattak reminiszcenciahatást; 3. a szűkebb reminiszcenciaövezet érvényességét, a személyek jól formáltsági csoportjaitól függetlenül, az emlékek kronológiai mintázatának és jól formáltságának összevetése is alátámasztja. Az önéletrajzi narratívumok elemzésében alkalmazott harmadik eljárás a történetek „általánosított tanulságait" kifejező indexelés (Schank, 1990, 1999). Mintánkban nem találtunk összefüggést a reminiszcenciahatás és a történetek indexelhetősége között, annak ellenére, hogy azok a személyek, akik koherens történeteket meséltek, egyben indexelhetőbb emlékekkel is rendelkeztek. Értelmezésünk szerint a jelentős események felidézését irányító általánosított tanulságok explicit használata nem köthető meghatározott életszakaszhoz, a koherens életút felépítéséhez viszont szükség van tanulságos emlékekre.
Coke combustion and gasification kinetics in ethane steam crackers
Authors: Heynderickx G. J. , Schools E. M. , Marin G. B. 
Published: March 2005

AbstractA simulation model for the development of the optimal decoking procedure of a steam cracker is constructed. It is based on experimental data for the process gas side coke combustion with oxygen and the process gas side coke gasification with steam, using coke samples taken from an industrial steam cracker. The texture changes of the coke during the combustion and gasification are accounted for. Different kinetic models are combined with a coke porosity model and different gas–solid reaction/diffusion models. The model parameters are estimated from the experimental data and model discrimination is performed. For the coke combustion the kinetic model is based on the dissociative chemisorption of oxygen on the active coke sites, whereas a general gas–solid reaction/diffusion model is required. The growth of the pores and the overlap of the pores during the coke combustion are found to compensate each other. For the coke gasification, the kinetic mechanism is based on the dissociative chemisorption of steam, whereas a uniform gas–solid reaction/diffusion model is used. © 2005 American Institute of Chemical Engineers AIChE J, 2005
Renpenning syndrome comes into focus

AbstractRenpenning syndrome represents a prototypic X‐linked mental retardation condition with full expression of the phenotype in males and little or no expression in females. The predominant clinical findings are microcephaly, long narrow face, short stature with lean body build, and small testes. Mental retardation, usually of severe degree, occurs in 95% of cases. Less than 20% of cases have major malformations, the most common being cardiac defects and cleft palate. Subsequent to the description of mutations in the polyglutamine tract binding protein 1 (PQBP1) in Sutherland–Haan syndrome, Hamel cerebropalatocardiac syndrome, MRX55, and two small XLMR families, a single nucleotide insertion has been found in the original family with Renpenning syndrome and an AGAG deletion in a second family with the Renpenning syndrome. Mutations have also been found in Golabi–Ito–Hall syndrome, Porteous syndrome, and an additional small family. It is now demonstrated that five named XLMR syndromes (Sutherland–Haan, Hamel cerebropalatocardiac, Golabi–Ito–Hall, Porteous, and Renpenning), one nonsyndromic family (MRX55), and three small XLMR families have PQBP1 mutations and are thus allelic XLMR entities. In acknowledgement of the historical importance of the original report of Renpenning syndrome [1962], we propose that the entities with PQBP1 mutations be combined under the name of Renpenning syndrome. © 2005 Wiley‐Liss, Inc.
The impact of operator involvement in pollution reduction: case studies in Canadian chemical companies
Authors: Boiral Olivier 
Published: March 2005

AbstractIn contrast to most environmental engineering processes, the effectiveness of employee involvement in pollution reduction seems uncertain, ambiguous and far from being clearly established. For companies whose environmental policies have long rested on technical investments, this uncertainty raises several essential questions, namely ‘what is the true effectiveness of this approach?’, ‘to what degree does employee involvement, most specifically operator involvement, make it possible to significantly and measurably reduce environmental impacts?’ and ‘what type of change could this induce in company operations?’. This article proposes answers to these questions based on an empirical study of the preventive and behavioural aspects of environmental management in the Canadian chemical industry. Conducted in three chemical factories from the Montreal region, the case studies show that significant results, often exceeding managers' expectations, could be obtained through the operators' involvement. However, these results and the precise organizational changes that caused them were difficult to identify, measure and foresee. Copyright © 2005 John Wiley & Sons, Ltd and ERP Environment.
Environmental issue management: towards a multi‐level theory of environmental management competence
Authors: Heugens Pursey P. M. A. R. 
Published: March 2005

AbstractThe continuity and profitability of business firms are under constant threat from environmental issues – forthcoming developments in the environmental domain or involving environmental stakeholders that are likely to have an important impact on the ability of the enterprise to meet its objectives. Managers must forge responses to such issues, but must they respond in an ad hoc fashion to every issue or can they develop more coherent environmental management competences? Empirical evidence was collected from a case study of the environmental issue management practices of Unilever, one of the largest food and personal care companies in the world. This company's approach to dealing with the issue of genetically modified ingredients reveals that issue managers face a complex level‐of‐analysis problem when confronting environmental issues: how to translate individual‐level knowledge into organization‐level outcomes? The theory developed here suggests that once firms learn how to span this chasm, they are able not only to address discrete environmental issues, but also to build competitive environmental advantages through the development of integrative organizational competences.

Multipotent stem cells from adult olfactory mucosa

Published: March 2005

AbstractMultipotent stem cells are thought to be responsible for the generation of new neurons in the adult brain. Neurogenesis also occurs in an accessible part of the nervous system, the olfactory mucosa. We show here that cells from human olfactory mucosa generate neurospheres that are multipotent in vitro and when transplanted into the chicken embryo. Cloned neurosphere cells show this multipotency. Multipotency was evident without prior culture in vitro: cells dissociated from adult rat olfactory mucosa generate leukocytes when transplanted into bone marrow–irradiated hosts, and cells dissociated from adult mouse olfactory epithelium generated numerous cell types when transplanted into the chicken embryo. It is unlikely that these results can be attributed to hematopoietic precursor contamination or cell fusion. These results demonstrate the existence of a multipotent stem‐like cell in the olfactory mucosa useful for autologous transplantation therapies and for cellular studies of disease.

Proof testing in support of the new San Francisco–Oakland Bay Bridge
Authors: Seible Frieder , Dazio Alessandro , Restrepo José I. 
Published: March 2005

AbstractFollowing the Loma Prieta earthquake, Caltrans (California Department of Transportation) started a multi‐year seismic vulnerability assessment and retrofit project of all major bridges in California, including the San Francisco–Oakland Bay Bridge (SFOBB) East Bay Span. First, a retrofit of the East Span Steel Truss structure was evaluated. However, owing to the high cost and the questionable reliability in terms of performance of the retrofit and owing to its difficult implementation under full traffic, a replacement structure was determined to provide a seismically more reliable alternative, resulting in the SFOBB East Span Replacement Project.The new bridge consists of four distinct structures: (1) the Oakland landing or touchdown structures; (2) a segmental concrete box girder crossing called the Skyway; (3) a self‐anchored suspension (SAS) signature span; and (4) a series of multi‐cell post‐tensioned concrete box girder bridges providing the transition to the tunnel on Yerba Buena Island. The new bridge will feature parallel roadways and will be built next to the existing bridge, which will be dismantled after the new bridge is opened to traffic.This paper focuses only on the seismic safety aspects in the RC elements of three of the four segments of the new SFOBB East Span Bridge, namely the Skyway, the SAS bridge and the Oakland touchdown. Analytical and numerical models were developed to assess the seismic behavior of the Bay Bridge and a large‐scale proof‐testing program was conducted at the Charles Lee Powell Structural Research Laboratories at the University of California, San Diego. In the framework of this program, two steel shear links at 100% scale were tested, two concrete piers of the Skyway at 25% scale, a 25% scale model of the West Anchor Pier W2, and two column 35% scale piers of the Oakland Touchdown were also tested.The large‐scale tests on all structural elements of the new East Span of the San Francisco–Oakland Bay Bridge with expected inelastic performance characteristics proved that the design fully meets all performance requirements. The large‐ or full‐scale tests were able to identify performance issues, resulting in design improvements and considerable cost savings. Alternative detailing and construction procedures were validated, leading to a more economic construction of the new bridge. Copyright © 2005 John Wiley & Sons, Ltd.
Seismic retrofit of George Massey Tunnel
Authors: Taylor Peter R. , Ibrahim Hisham H. , Yang Dan 
Published: March 2005

AbstractThe 629 m long immersed George Massey Tunnel passes under the south arm of the Fraser River near Vancouver, British Columbia. The tunnel was completed in 1959. Based on current seismic design standards, the precast concrete structure is grossly under‐reinforced in the longitudinal direction. Buckland & Taylor Ltd was retained by the Ministry of Transportation of British Columbia to conduct a seismic assessment and final design for the seismic safety retrofit of the tunnel. A number of vulnerabilities were identified including soil liquefaction in the loose jetted sand and native deposits underneath the tunnel, resulting in tunnel flotation, large differential lateral displacements, and post‐liquefaction consolidation settlements, subsequently imposing large tensile and compressive forces in the weak tunnel joints. The situation of cracking and water leakage potentially creates a life hazard in the event of a major earthquake. During the final design, detailed non‐linear dynamic geotechnical analyses were conducted to study the effects of soil liquefaction and to evaluate ground improvement measures. Detailed structural analyses were also conducted considering different proposed retrofit schemes to enable the tunnel section to handle the soil displacement demands. Centrifuge model testing was used to calibrate and verify the liquefaction characteristics predicted by the numerical models and the proposed densification and gravel drainage techniques. Field testing of gravel drains was performed to collect data on the performance of different types of gravel drains. Copyright © 2005 John Wiley & Sons, Ltd.
Spatial and temporal expression of S100B in cells of oligodendrocyte lineage
Authors: Hachem S. , Aguirre A. , Vives V. , Marks A. , Gallo V. , Legraverend C. 
Published: March 2005

AbstractThe analysis of oligodendrocyte (OL) lineage development has been facilitated by the immunocytochemical characterization of OL‐specific antigens and definition of the phenotypes sequentially acquired by differentiating OLs. The purpose of the present study was to address an enduring discrepancy between several reported cases of S100B immunodetection in CNS myelin and myelinating OLs on the one hand, and the systematic use of the S100B protein as an alleged astrocytic marker in studies of the mammalian CNS on the other. To resolve this discrepancy, we have compared the developmental distribution of EGFP+ cells in the CNS of s100b‐enhanced green fluorescent protein (EGFP) (Vives et al., 2003) and cnp‐EGFP (Yuan et al., 2002) mice, and examined the degree of overlap between EGFP expression and that of stage‐specific markers of OL differentiation during the embryonic and postnatal phases of development. We demonstrate that the S100B protein is expressed in postnatal and adult populations of NG2+ progenitors of mouse brain, as well as in immature and mature myelinating OLs present in the brain and spinal cord of embryonic and adult mice, respectively. Comparison between EGFP and endogenous S100B expression in the s100b‐EGFP and cnp‐EGFP mice indicates that S100B protein expression is upregulated in immature and mature OLs. These results argue against the current view that S100B expression is restricted to the astrocytic lineage in the CNS, and indicate that the use of S100B in combination with other molecular markers will help discriminate oligodendrocytes from astrocytes. © 2005 Wiley‐Liss, Inc.
Quality of life, mucositis, and xerostomia from radiotherapy for head and neck cancers: A report from the NCIC CTG HN2 randomized trial of an antimicrobial lozenge to prevent mucositis

Published: March 2005

AbstractBackground.The National Cancer Institute of Canada Clinical Trials Group undertook a multicenter, randomized, double‐blind controlled trial of an oral antimicrobial versus placebo to prevent and treat mucositis. We present the quality of life (QOL) analysis for this trial.Methods.One hundred thirty‐eight patients were randomly assigned. QOL data were collected every 2 weeks before, during, and after radiotherapy. The European Organization for Research and Treatment of Cancer Quality of Life questionnaire (EORTC QLQ‐C30) and a Trial Specific Checklist (TSC) were used.Results.The antimicrobial lozenge did not impact QOL. The principal acute side effect of radiotherapy is oral pain, affecting more than 90% of patients. Role function is impacted during treatment, and patients experience fatigue. Appetite was reported to markedly increase during radiotherapy. There was a dramatic and persistent increase in dry mouth.Conclusions.This study highlights the benefits of combining the EORTC QLQ‐30 with an “oral” TSC in a randomized controlled trial and provides valuable baseline data for their use with an objective mucositis scoring system. © 2005 Wiley Periodicals, Inc.

An interaction between apolipoprotein E and TERE1 with a possible association with bladder tumor formation
Authors: McGarvey Terence W. , Nguyen Trang B. , Malkowicz S. Bruce 
Published: March 2005

AbstractTERE1, a recently discovered gene/protein appears to play a role in bladder tumor growth regulation but to date does not have clear functional correlates. The objective of this study was to gain further insight into the function of the TERE1 protein by identifying potential protein to protein interactions with TERE1 and determining whether these interactions are associated with putative growth regulatory pathways and/or bladder tumor formation. Towards this aim, we have performed a bacterial two hybrid assay and isolated interacting clones, which then were sequenced and further examined by affinity chromatography and immunoprecipitation. From among several positive clones, we isolated a putative interacting plasmid containing the C‐terminal portion of preapolipoprotein E starting from amino acid number 124 from the pBT‐TERE1/pTarget‐cDNA bacterial two hybrid system. The C‐terminal portion of apoE interaction with the TERE1 was confirmed using ProBond columns by the expression of 6XHis recombinant and 35S methionine/cysteine labeled proteins. We found that there was ubiquitous expression of the apoE transcript in normal bladder and in various grades and stages of transitional cell carcinoma (TCC) of the bladder. Likewise, we detected the apoE protein in both normal and malignant bladder tissues by Western blot. There was a significant decrease in the apoE protein in 12 of 16 muscle invasive TCCs of the bladder compared to normal bladder mucosa samples. Previous studies in rat fibroblasts have found that expression of apoE can decrease the phosphorylation of the growth factor‐related p42/44 MAP kinase. A significant decrease in p44/p42 MAPK phophorylation was also apparent using a phosphorylation specific antibody in human 293 kidney cells upon transfection and expression of apoE. In conclusion, the results from this study suggest that the expression and regulation of the apoE pathway may yield clues toward understanding the function of TERE1. © 2005 Wiley‐Liss, Inc.
Unavoidable cycle lengths in graphs
Authors: Verstraete Jacques 
Published: March 2005

AbstractAn old conjecture of Erdős states that there exists an absolute constant c and a set S of density zero such that every graph of average degree at least c contains a cycle of length in S. In this paper, we prove this conjecture by showing that every graph of average degree at least ten contains a cycle of length in a prescribed set S satisfying $|S \cap \{ 1,2,\ldots ,n\} | = O(n^{0.99})$. © 2005 Wiley Periodicals, Inc.

Effects of beam polarization on coherent anti‐Stokes Raman scattering using noisy light
Authors: Aung Pye Phyo , Cosert Krista M. , Weisel Lindsay R. , Schulz Tanner F. , Gealy M. W. , Ulness Darin J. 
Published: March 2005

AbstractThe effects of different linear polarization schemes on the noisy light‐based coherent anti‐Stokes Raman scattering [I(2)CARS] signal were investigated. It was found that certain polarization schemes can selectively shut down the contributions from terms represented by various factorized time correlation (FTC) diagrams to the I(2)CARS spectrogram. FTC diagram analysis was used in conjunction with the symmetry properties of the hyperpolarizability to provide a theoretical understanding of this phenomenon and serve as the basis for simulation of the I(2)CARS spectrogram. Striking agreement is seen between the simulations and the experimental results for benzene and several methylated benzene derivatives. Copyright © 2005 John Wiley & Sons, Ltd.
Spectroscopic identification of alizarin in a mixture of organic red dyes by incorporation in Zr‐Ormosil
Authors: Murcia‐Mascarós S. , Domingo C. , Sanchez‐Cortes S. , Cañamares M. V. , Garcia‐Ramos J. V. 
Published: March 2005

AbstractRaman and UV–visible spectroscopy were applied to the study of a mixture of alizarin and carminic acid, two highly fluorescent anthraquinone dyes. The selective incorporation of alizarin into a Zr‐Ormosil polymer induced intense Raman spectra that allow an easy, quick and unequivocal identification of this dye. Therefore, this method can be applied to the separation and identification of dyes, which is an important issue in the field of archaeometry. Raman spectroscopy was used to identify alizarin in Zr‐Ormosil at different pH values, solvents and dye concentrations. The best conditions for composite formation were determined. Moreover, the Raman spectra allow us to propose an interaction model for the alizarin–Zr complexes where the monoanionic alizarin forms a chelate with Zr cations in the doped Ormosil similar to the alizarin–Al chelate formed in lacs and alizarin–Ag chelate formed in SERS experiments.

Infrared and Raman spectra of ethyl trifluoromethanesulfonate, CF3SO2OCH2CH3. An experimental and theoretical study
Authors: Tuttolomondo M. E. , Navarro A. , Varetti E. L. , Ben Altabef A. 
Published: March 2005

AbstractThe infrared spectra of CF3SO2OCH2CH3 in the gaseous and liquid states and the Raman spectrum of the liquid were obtained. Quantum chemistry calculations using density functional theory were used to predict the most stable geometry and conformation of the studied molecule. Subsequently, the harmonic vibrational wavenumbers and force field were calculated. An assignment of the observed spectral features made after comparison with related molecules and with the predicted wavenumbers was used as the basis of a scaling of the original force field in order to reproduce as well as possible the experimental wavenumbers. With this purpose, a set of scale factors was calculated by a least‐squares procedure, leading to a final root mean square deviation of 12.0 cm−1. Copyright © 2005 John Wiley & Sons, Ltd.

Published: March 2005

AbstractA progressive supranuclear palsy (PSP)‐like syndrome due to vascular or anoxic brain insult is rare. We describe a 65‐year‐old man with a progressive PSP‐like phenotype associated with hypoxic–ischemic bilateral striopallidal lesions, secondary to rupture of and subsequent surgery for a thoracic aortic aneurysm. After early extrapyramidal features, 10 months later he started to fall, and developed levator inhibition. A supranuclear gaze palsy for downgaze was documented 5.5 years after the insult. © 2005 Movement Disorder Society
