Visual search editor for composing meta searches
Authors: Spoerri Anselm 
Published: September 2005

AbstractMetaCrystal is visual tool for creating and editing meta search queries. Users can visually combine the top results retrieved by different search engines to create crystals of increasing complexity. MetaCrystal consists of several overview tools to help users gain insight into how to filter the results from the different engines. It shows users the degree of overlap between the top results returned by different search engines. Users can apply different weights to the search engines to create their own ranking functions and can perform advanced filtering operations visually. Users can modify the URL directory depth or change the number of top documents used to increase or decrease the degree of overlap between the different engines. MetaCrystal addresses the problem of the effective fusion of different search engine results by enabling user to visually compose and refine meta searches.
Speak now and forever record your piece: Information use in technical trouble tickets
Authors: Marlow David W. , Nyce James M. 
Published: September 2005

AbstractBased on a bimodal approach combining elements of the ethnography of communication and organizational genre analysis, this study examines the text of a large corpus of trouble ticket discourse. Key findings involve the fragmentary nature of trouble ticket text, the role the system plays in the use of information, the duality of writers' intention for the use of information, and the collaboratively concatenative generation of trouble tickets.Directions for future study include the evolution of the trouble ticket genre over time, the affect of gender on communicative style, readers' reactions to trouble tickets, and the role of trouble tickets play in organizational memory.
Managing and assessing internet service needs and use of under‐served populations at public libraries
Authors: Kim Yunkeum 
Published: September 2005

AbstractAs the range of public library services with new technology has diversified, defining, measuring, assessing and managing the quality of these electronic services has become a critical issue. Internet connections at public libraries have increased dramatically since 1990 due to the availability of key external funding sources. The major goal of those funding sources was to expand public access to Computers and digital information, especially for the public of low‐income or under‐served populations; thus, there has been continuing increase in public library Internet services at the library, for example, the services at Internet workstations. Although there have been attempts to measure the performance of public library network services by library and information science researchers using network statistics based on “technical‐driven” performances, there has been little research dealing with service quality and satisfaction of Internet service users at the public libraries based on “user‐driven” performance evaluation. This paper describes the process of survey research using 386 Internet service users at four public libraries and discusses how public libraries need to approach those under‐served populations' Information needs and use at Internet workstations which can expand the possibility of new direction for future public library Internet services.
A conceptual framework for the holistic measurement and cumulative evaluation of library services
Authors: Nicholson Scott 
Published: September 2005

AbstractThis conceptual piece presents a framework to aid libraries in gaining a more thorough and holistic understanding of their users and services. Through a presentation of the history of library evaluation, a measurement matrix is developed that demonstrates the relationship between the topics and perspectives of measurement. These measurements are then combined through evaluation criteria, and then different participants in the library system view those criteria for decision‐making. By implementing this framework for holistic measurement and cumulative evaluation, library evaluators can gain a more holistic knowledge of the library system and library administrators can be better informed for their decision‐making processes.
Rank‐normalized impact factor: A way to compare journal performance across subject categories
Authors: Pudovkin Alexander I. , Garfield Eugene 
Published: September 2005

AbstractIt is well known that uninformed science administrators often use ISI's journal impact factors without taking into account the inherent citation characteristics of individual scientific disciplines. A rank normalized impact factor (rnlF) is proposed which involves use of order statistics for the complete set of journals within each JCR category. We believe the normalization procedure provides reliable and easily interpretable values. For any journal j, its rnlF is designated as rnlF1and equals (K–R1+ 1)/K, where R1 is the descending rank of journal j in its JCR category and K is the number of journals in the category. Note: JCR impact factor listings are published in descending order. The proposed rnlF is compared with normalized impact factors proposed by earlier authors. The efficacy of the rnlF is illustrated in the cases of seven highly‐cited scientists, one each from seven different fields.
Can web citations be a measure of impact? An investigation of journals in the life sciences
Authors: Vaughan Liwen , Shaw Debora 
Published: September 2005

AbstractWe examine traditional and Web citations to journal articles in biology and genetics. There is significant correlation between citations in these two formats. Journals with higher numbers of Web citations tend to have more citations indicating intellectual impact (citations from papers or class readings, in contrast to citations from bibliographic services or the author's or journal's home page). Web citations show a broader geographic coverage and capture a greater number and variety of uses of journal articles.

Authors: Chemetov N. 
Published: September 2005

AbstractThe aim of this paper is to study shape memory alloys which admit two shape memory effect. This effect results from progressive modification of the admissible mixture of martensites and austenite. The predictive theory of this education phenomenon has been developed by Frémond. We discuss the education model of Frémond and establish the solvability and uniqueness results. Copyright © 2005 John Wiley & Sons, Ltd.
Outcome of urethral closure in patients with neurologic impairment and complete urethral destruction
Authors: Stoffel John T. , McGuire Edward J. 
Published: September 2005

AbstractAimsThe purpose of this study is to describe the problems associated with prolonged urethral catheterization in 12 patients with neurological problems and to report the results of surgical treatment.MethodsA retrospective study of patients with neurogenic bladder and urethral dysfunction treated with prolonged catheterization resulting in incontinence associated with loss of urethral tissue and or function selected 12 patients. All had video urodynamics. Twelve were continuously incontinent despite a catheter. Bladder compliance, where that could be measured, was low is 10, and there were multiple and serious co‐morbidities including sepsis, hypoalbuminemia, skin breakdown, osteomyelitis, respiratory insufiency, etc. There were 4 males and 8 females, 9 had a spinal cord injury and 3 progressive multiple sclerosis.ResultsMale patients underwent transperineal closure of the membranous urethra; females transvaginal closure of the urethra. All patients had a urinary diversion, either an ileovesicostomy, or an augmentation cystoplasty and construction of a neourethra. Continence was ultimately achieved in 11 of 12 patients at a median 20 months. Four patients had one additional procedure to gain continence, but five patients required 3.8 procedures/patient to achieve continence. Closure of the male urethra was more easily accomplished than closure of an extensively damaged eroded female urethra.ConclusionsPatients with urethral damage and erosion related to prolonged catheter present a formidable challenge in surgical reconstruction. Most have serious co‐mobidities and a single operation does not usually solve all the problems. Persistence does almost always result in continence. Neurourol. Urodynam. © 2005 Wiley‐Liss, Inc.
Visceral and cutaneous sensory testing in patients with painful bladder syndrome
Authors: FitzGerald Mary P. , Koch Dorothea , Senka Judith 
Published: September 2005

AbstractAimsOur aims were to determine whether subjects with painful bladder syndrome (PBS) demonstrate characteristics of visceral pain syndromes: visceral hyperalgesia, expanded loci of referral of bladder sensation, increased bladder pain with repetitive filling, lower thresholds to cutaneous stimulation in relevant dermatomes, abnormal response to repetitive cutaneous stimulation in relevant dermatomes, and also to develop easily applied measures for PBS pain evaluation and management.MethodsWe recruited PBS subjects and control subjects with no bladder pain and with either stress urinary incontinence (SUI) or no incontinence. Subjects underwent three bladder fills up to maximum 300 ml and mapped bladder fullness/discomfort, rating any pain present. Cutaneous current perception thresholds (CPTs) were tested at 2000 Hz, 250 Hz, 5 Hz at C5, T6, T10, T12, S3 dermatomes. Repetitive supra‐threshold stimulation in trains of 15 stimuli 2 sec apart were then administered to T12, S3 dermatomes.ResultsPBS subjects demonstrated hyperalgesia to bladder filling and tended to sense bladder discomfort at both suprapubic and vulvar/urethral sites. There was no difference in CPTs at any dermatome at any stimulating frequency. PBS and SI subjects tended not to habituate to repetitive stimuli, while asymptomatic controls tended to habituate to repetitive stimulation.ConclusionsPBS subjects demonstrate bladder hyperalgesia and may sense bladder discomfort at sites other than suprapubic. Rating of bladder discomfort and sensory mapping during cystometry usefully distinguishes between PBS subjects and controls. Neurourol. Urodynam. © 2005 Wiley‐Liss, Inc.
Transshipment through crossdocks with inventory and time windows
Authors: Lim Andrew , Miao Zhaowei , Rodrigues Brian , Xu Zhou 
Published: September 2005

AbstractA major challenge in making supply meet demand is to coordinate transshipments across the supply chain to reduce costs and increase service levels in the face of demand fluctuations, short lead times, warehouse limitations, and transportation and inventory costs. In particular, transshipment through crossdocks, where just‐in‐time objectives prevail, requires precise scheduling between suppliers, crossdocks, and customers. In this work, we study the transshipment problem with supplier and customer time windows where flow is constrained by transportation schedules and warehouse capacities. Transportation is provided by fixed or flexible schedules and lot‐sizing is dealt with through multiple shipments. We develop polynomial‐time algorithms or, otherwise, provide the complexity of the problems studied. © 2005 Wiley Periodicals, Inc. Naval Research Logistics, 2005
A Cauchy‐stress based solution for a necking elastic constitutive model under large deformation
Authors: Olley P. 
Published: September 2005

AbstractA finite element based method for solution of large‐deformation hyperelastic constitutive models is developed, which solves the Cauchy‐stress balance equation using a single rotation of stress from principal directions to a fixed co‐ordinate system. Features of the method include stress computation by central differencing of the hyperelastic energy function, mixed integration‐order incompressibility enforcement, and an iterative solution method that employs notional ‘small strain’ stiffness. The method is applied to an interesting and difficult elastic model that replicates polymer ‘necking’; the method is shown to give good agreement with published results from a well‐established finite element package, and with published experimental results. It is shown that details of the manner in which incompressibility is enforced affects whether key experimental phenomena are clearly resolved. Copyright © 2005 John Wiley & Sons, Ltd.
Numerical investigation of the stress field of particulate reinforced polymeric composites subjected to tension
Authors: Kakavas Panayiotis A. , Kontoni Denise‐Penelope N. 
Published: September 2005

AbstractThe aim of the present study is the detailed numerical investigation of the stress/strain distribution in polymeric matrix composites reinforced with spherical inclusions, using the finite element method (FEM). Perfect adhesion between the matrix and the inclusions was assumed and from the computed stress/strain profiles of the system, debonding initiation and propagation can easily be predicted. Analytical models available in the literature may predict the stress/strain distribution within the inclusion and along the matrix/inclusion interface, while the FEM may yield results for the whole composite, including within the inclusions. Three typical volume fractions of the composite were examined and the results were justified by the analytical predictions of other researchers. The numerical results show that the matrix starts to debond from the inclusions at angular distance forty‐five degrees and as the applied load increases the debonding zone gradually extends.

Scanning for chorionicity: comparison between sonographers and perinatologists
Authors: Weisz Boaz , Pandya Pranav , Dave Raj , Jauniaux Eric 
Published: September 2005

AbstractObjectiveIn most prenatal settings, twin pregnancies are initially evaluated by sonographers. Pregnancies diagnosed as monochorionic are subsequently referred to perinatologists or specialists in fetal medicine for the confirmation of chorionicity. In order to assess this screening strategy, we have compared the diagnosis of chorionicity made by the sonographers in the ultrasound department with the diagnosis done in the fetal medicine unit.MethodsA cohort of women presenting with twin pregnancy and booked for prenatal care at University College London Hospitals over a 4‐year period were investigated prospectively. All women were scanned at their initial visit at 11–14 weeks in the ultrasound department (US), and were subsequently referred to the Fetal Medicine Unit (FMU) for a second ultrasound evaluation. Ultrasound data were compared and diagnosis of chorionicity was confirmed by examination of the inter‐twin membranes after delivery.ResultsChorionicity was determined in 172 twin cases by the two different departments. The overall rate of concordant chorionicity determination between both units was 90.1%. The rate of discordant results in dichorionic pregnancies was extremely small, 1 in 119 pregnancies (0.8%). The rate of discordant results for monochorionic diamniotic pregnancies was 5.5%. Monoamniotic pregnancies were over‐diagnosed by the US technicians.DiscussionThese results demonstrate that DC/DA chorionicity is accurately determined by sonographers at less than 14 weeks. In our opinion, it is both efficient and safe to rely on the diagnosis of the sonographers in DC/DA pregnancies in early pregnancy. In such pregnancies, a decision can be made either not to refer these patients for further evaluation of chorionicity by the fetal medicine team or to postpone the referral to after 14 weeks.

Prenatal screening for Down syndrome and neural tube defects in twin pregnancies
Authors: Wald Nicholas J. , Rish Simon 
Published: September 2005

AbstractPrenatal screening and diagnosis in a twin pregnancy is not straightforward. Once a twin pregnancy has been identified, women and their partners need time to consider the implications and decide whether they wish the pregnancy to be screened for Down syndrome or neural tube defects. We discuss here how multiple marker screening for Down syndrome and alpha‐fetoprotein screening for neural tube defects can be carried out, given that this is the parents' chosen option and that the health professionals involved are capable of performing a diagnosis and selective feticide, should this arise.

Prenatal diagnosis and management of twin pregnancies complicated by a co‐existing molar pregnancy
Authors: Wee Ling , Jauniaux Eric 
Published: September 2005

AbstractRecent advances in ultrasound and molecular genetics have increased our understanding and hence enhanced the perinatal management of complete and partial hydatidiform mole. By contrast, the management of a twin pregnancy combining a normal pregnancy with a normal fetus and a complete hydatidiform mole (CHM) remains complex and controversial due to conflicting data from different parts of the world. The aim of this review is to analyse the international literature on twin pregnancies that include a mole, present the complications and outcome of pregnancy and to discuss the perinatal management. Management is complicated and women should be counselled about the maternal and fetal complications, and the pregnancy monitored carefully by a perinatal team with experience in high‐risk obstetrics and access to neonatal care. The data reviewed here suggest that a woman who decides to continue with the pregnancy including a CHM must be aware that, overall, she only has a one in four chance of live birth and in around 35% of cases she will develop persistent trophoblastic disease (PTD) after delivery. In ongoing pregnancies, there will be, in at least 20% of the cases, an early onset of pre‐eclampsia (PET) and a 29% risk of fetal loss due to late miscarriage, intrauterine death and neonatal death. Maternal serum human chorionic gonadotrophin (MShCG) could be useful in predicting outcome in twin pregnancy combining normal pregnancy and CHM, but this needs to be investigated prospectively.

Modification of microstructures and physical properties of ultra high molecular weight polyethylene by electron beam irradiation
Authors: Lee Sang Man , Choi Sun Woong , Nho Young Chang , Song Hyun Hoon 
Published: September 2005

AbstractAn ultra high molecular weight polyethylene was irradiated with the electron beam at dose levels ranging from 100 kGY to 1 MGy. The microstructures of the irradiated samples were characterized by FTIR, gel fraction measurement, DSC, and small‐ and wide‐angle X‐ray scattering. For the mechanical properties, a static tensile test and creep experiment were also performed. The crosslinking and the crystal morphology changes were the main microstructural changes to influence the mechanical properties. It was found that 250 kGy appeared to be the optimal dose level to induce crosslinks in the amorphous area and recrystalliztion in the crystal lamellae. At doses above 250 kGy, the electron beam penetrates into the crystal domains, resulting in crosslinks in the crystal domains and reduction in the crystal size and crystallinity. The static mechanical properties (modulus, strength) and the creep resistance were enhanced by the electron beam irradiation. The stiffness rather correlated with the degree of crosslinks while the strength with the crystal morphology. © 2005 Wiley Periodicals, Inc. J Polym Sci Part B: Polym Phys 43: 3019–3029, 2005
Fabrication of Bioactive Surfaces by Plasma Polymerization Techniques Using a Novel Acrylate‐Derived Monomer

Published: September 2005

AbstractSummary: Material coating of surfaces can enhance receptivity for cells and biological compounds. Existing plasma coating technologies and possible materials are limited. A new polymer from pentafluorophenyl methacrylate (PFM) monomer was synthesized, and was plasma enhanced chemical vapor deposited on silicon wafers. The optimal plasma polymerization parameters for the PFM monomer and its copolymerization with the cross‐linking agents 1,7‐octadiene and 1,4‐butanediol divinyl ether co‐monomers were established. All the resulting polymer coatings leave the labile pentafluorophenyl group on the surface, enabling a rapid reaction with an amino‐terminated biotin ligand and allowing layer‐by‐layer self‐assembly of biotin‐streptavidin. In addition, the deposited polymer layers showed an extremely flat morphology with a nanoscale average roughness. This approach provides an easy means of obtaining functionalized surfaces which can enhance and control the biocompatibility of bulk materials. Merging the versatility of plasma polymerization processes, via simple monomers and reaction conditions, with biological platforms that enable target of cell adhesion brings us closer to the ultimate goal of controlling cell function through structured surfaces for their application in tissue engineering.Schematic representation of a functionalized surface obtained by plasma polymerization of the PFM monomer, showing labile pentafluorophenyl groups on the surface.magnified imageSchematic representation of a functionalized surface obtained by plasma polymerization of the PFM monomer, showing labile pentafluorophenyl groups on the surface.
Improvement of Surface Properties of Poly(propylene) Hollow Fiber Microporous Membranes by Plasma‐Induced Tethering of Sugar Moieties
Authors: Yu Hai‐Yin , Hu Meng‐Xin , Xu Zhi‐Kang 
Published: September 2005

AbstractSummary: Hydrophobic poly(propylene) hollow fiber microporous membranes (PPHFMMs) were surface‐modified by nitrogen plasma‐induced tethering of α‐allyl glucoside (AG). Their antifouling characteristics in a submerged membrane bioreactor (SMBR) were investigated. The chemical composition of the modified and unmodified PPHFMMs was characterized by X‐ray photoelectron spectroscopy (XPS). Water contact angle was measured by the sessile drop method. Results of XPS clearly indicated that sugar moieties could be tethered on the membrane surface. Water contact angle on the modified membrane showed a minimum value of 64°, approximately 64° lower than that on the unmodified membrane. After continuous operation in a SMBR for about 160 h, the flux recovery, the reduction of flux and the relative flux ratio for the modified PPHFMMs were 17.8% higher, 5.1% lower and 140% higher than those of the nascent one, respectively.Schematic representation of plasma‐induced tethering of α‐allyl glucoside on a PPHFMM surface.magnified imageSchematic representation of plasma‐induced tethering of α‐allyl glucoside on a PPHFMM surface.
Microscope Raman scattering and X‐ray diffraction study of near‐stoichiometric Ti:LiNbO3 waveguides
Authors: Zhang De‐Long , Siu G. G. , Pun E. Y. B. 
Published: September 2005

AbstractThe crystalline phase within guiding layers of near‐stoichiometric strip and planar Ti:LiNbO3 wave‐guides, prepared by the method of simultaneous work of vapour transport equilibration (VTE) treatment and indiffusion of Ti film, was studied by combined confocal microscope Raman scattering and X‐ray powder diffraction. The results show that the strip and planar waveguide layers still retain the LiNbO3 phase and no other non‐LiNbO3 phases can be identified within the guiding layer. Li/Nb ratios inside and outside the strip and planar waveguide layers were determined from the microscope Raman scattering results and compared to those obtained from the measured optical absorption edge. It is shown that the Li/Nb ratios are homogeneous within the waveguide layer and are close inside and outside the waveguide layer. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
