Investigating the relation between the secondary yield enhancement and the structure of the metallic overlayer in metal‐assisted SIMS
Authors: Nittler L. , Delcorte A. , Bertrand P. , Migeon H.‐N. 
Published: May 2010

AbstractPristine and Au‐covered molecular films have been analyzed by ToF‐SIMS for different amounts of evaporated gold. In contrast to other MetA‐SIMS studies, the metallization of the high‐mass polymers (polycarbonate and polystyrene) was carried out in situ. The evaporation flux was monitored with a quartz‐crystal microbalance, and the exact quantity of deposited gold was determined by XPS. It was found that the sticking coefficient of gold on these polymers is less than one. The evolution of the secondary ion yield using Argon ion bombardment is studied as a function of the total amount of deposited metal. Furthermore, the SIMS results are accompanied by a detailed characterization of the sample surfaces morphology, in order to check any possible relation between the structure of the deposited metallic film and the yield enhancement of S‐SIMS signals.

AbstractVPD‐SIMS and VPD‐TOFSIMS are used to detect ultra low level of metallic contaminants on silicon wafer surface. The combination of Secondary Ion Mass Spectrometry (SIMS) high sensitivity and Vapor Phase Decomposition (VPD) is capable to provide quantitative detection of metals with sub‐107 at/cm2 detection limits on 200 mm and 300 mm silicon wafers surface. The quantification is validated by a correlation with Total X Ray Fluorescence (TXRF) measurements. This study sets down the quantification problematic and describes the protocol that was developed for the analysis and quantification. This complementary technique to VPD‐TXRF improves the detection of metallic contamination on silicon surface for the most advanced semiconductor technology. Copyright © 2010 John Wiley & Sons, Ltd.
Chemical composition and microstructure of waxy plant surfaces: triterpenoids and fatty acid derivatives on leaves of Kalanchoe daigremontiana
Authors: Jetter Reinhard , Sodhi Rana 
Published: May 2010

AbstractThe vast surfaces of plant leaves are protected by a coating of cuticular waxes. While the bulk composition of wax mixtures from various plant species has been reported, chemical information on the outermost leaf surface is lacking to date. The goal of the present study was to explore the use of ToF‐SIMS for surface analyses of plant leaves of the species Kalanchoe daigremontiana. It was found that the two major wax triterpenoids, glutinol and friedelin, were both present at the lower leaf surface in high concentrations. In contrast, the predominant wax alkane, tritriacontane, was not detectable by ToF‐SIMS. Three other unidentified compounds that had not been detected in the bulk wax mixture were present at the surface, further demonstrating that the outermost layer of molecules differed drastically in composition from the underlying wax mixture. Mapping experiments showed that all compounds were distributed fairly homogenously across the lower leaf surface, exhibiting no apparent gradients across epidermal cells and within the surface area of individual cells Copyright © 2010 John Wiley & Sons, Ltd.
FIB‐SIMS analysis of an aluminum alloy/SiC metal matrix composite
Authors: Silk Jonathan R. , Dashwood Richard J. , Chater Richard J. 
Published: May 2010

AbstractPolished surfaces of a fine‐grained aluminum, silicon carbide metal matrix composite (MMC) were imaged using the ion‐induced secondary electron emission in a FIB ion microscope. In these images a dispersion of particles with a distinct bright contrast are seen to be mainly located at the matrix aluminum grain/subgrain boundaries, and at the matrix/reinforcement interface. The particles range in size from 20 to 200 nm. FIB‐SIMS was used to identify the composition of these particles as magnesium and oxygen‐rich, and so, to corroborate SEM/EDS analyses. Analysis of the FIB images of the polished section showed that the areal density of the particles with distinct bright contrast was consistent with a composition of MgAl2O4.

Published: May 2010

AbstractThe effect of incorporating zirconium dioxide in TiO2 mesoporous films was investigated. Improved stability of the mesoporous structure of the synthesized TiO2/ZrO2 nanocomposites could be related to the suppression of titania crystallites growth and the formation of Ti1−xZrxO2 solid solution, as was inferred by the results of optical properties, AFM, XRD and XPS investigations.

Depressive symptoms and bodily pain: the role of physical disability and social stress
Authors: Gayman Mathew D. , Brown Robyn Lewis , Cui Ming 
Published: May 2010

AbstractThis study evaluates the bi‐directional association between depressive symptoms and bodily pain, and examines the role of physical disability and perceived social stress in the depression–pain relationship. Data are employed from a two‐wave panel study of Miami‐Dade county residents (n = 1459) that includes a substantial over‐sampling of individuals who identify as physically‐disabled. Findings indicate that the bi‐directional relationship between depression and pain is similar for those with and without a physical disability. Results also demonstrate that stress exposure, specifically recent life events and daily discrimination, partially mediated the relationship between prior levels of depression and changes in pain. Directions for future research and the need for a more comprehensive model of health incorporating physical, psychological, and social factors are discussed. Copyright © 2010 John Wiley & Sons, Ltd.
Defining a strategy for development of systems capability in the workforce
Authors: Davidz Heidi L. , Martin James N. 
Published: May 2010

AbstractAs systems increase in complexity, many organizations face an increasing need to improve the systems capability of their workforce. Systems engineering, systems integration, and system architecting skills are needed, yet many organizations struggle with designing an effective strategy for developing these organizational capabilities. This paper discusses how an organization might define a strategy to more efficiently develop systems capability in its workforce. In addition to listing considerations in defining a development strategy, existing methods used for developing systems capability are compared. With a more thorough understanding of the strengths and weaknesses of various systems capability development methods, organizations can customize a better development strategy for their unique systems capability needs. © 2010 Wiley Periodicals, Inc.

Aberrant right subclavian artery at 16 to 23 + 6 weeks of gestation: a marker for chromosomal abnormality
Authors: Borenstein M. , Minekawa R. , Zidere V. , Nicolaides K. H. , Allan L. D. 
Published: May 2010

AbstractObjectivesThis study was carried out to determine the feasibility of defining the position of the right subclavian artery (RSA) by fetal echocardiography between 16 and 23 weeks of gestation, and the association between an aberrant right subclavian artery (ARSA) and chromosomal and cardiac defects.MethodsWe examined the position of the RSA in all patients who attended our unit for a fetal cardiac scan. The assessment was carried out using a transverse view of the fetal chest sweeping up from the level of the aortic arch, using color flow mapping. An ARSA was diagnosed when this vessel was not seen in the normal position and an arterial vessel was seen crossing behind the trachea towards the right arm, arising as a fourth branch of the aortic arch, at a lower level than normal.ResultsThe course of the RSA could be identified in more than 95% of the 2799 fetuses examined between 16 and 23 + 6 weeks of gestation. An ARSA was found in 43 fetuses. The incidence was 1.5% in normal fetuses, 28.6% in fetuses with trisomy 21, 18.2% in fetuses with trisomy 18 and 8% in fetuses with other chromosomal defects. There was an association between an ARSA and cardiac defects in seven of the 43 fetuses (16%), and three of these seven fetuses had a normal karyotype.ConclusionsAssessment of the RSA by a fetal cardiologist is possible in almost all cases. The finding of an ARSA is much more common in fetuses with chromosomal defects, in particular trisomy 21 (where the prevalence of an ARSA was 29%), compared with euploid fetuses. Moreover, the presence of an ARSA may be associated with an increased incidence of intracardiac malformations. Examination of the position of the RSA is likely to become a routine ultrasound marker for chromosomal abnormalities in the second trimester of pregnancy. Copyright © 2010 ISUOG.

AbstractBackgroundLong‐term hemodynamic effects and clinical outcomes after balloon‐occluded retrograde transvenous obliteration (B‐RTO) remain unclear. The purpose of this study was to evaluate long‐term clinical results and effects on portal hemodynamics after B‐RTO for the treatment of gastric varices with spontaneous gastrorenal shunt.MethodsA total of 21 patients with cirrhosis and gastric varices treated by B‐RTO were evaluated. The cumulative survival rate was calculated, portal blood flow was measured by Doppler ultrasonography, and liver function was estimated on the basis of Child‐Pugh classification before and 1 year after B‐RTO.ResultsGastric varices disappeared or decreased markedly in size in all patients. Overall cumulative survival rates at 1, 3 and 5 years were 90.48, 71.11 and 53.71%, respectively. Portal blood flow increased significantly from 681.9 ± 294.9 to 837.0 ± 279.1 ml/min (p = 0.0125) after B‐RTO. Child‐Pugh score was not significantly changed (p = 0.755) after obliteration, but serum albumin was elevated significantly from 3.49 ± 0.49 to 3.75 ± 0.53 g/dl (p = 0.0459). The ascites score was significantly increased (p = 0.0455) after B‐RTO, but all cases of ascites could be controlled with medication.ConclusionsBalloon‐occluded retrograde transvenous obliteration is a safe and effective treatment for gastric varices with gastrorenal shunt. Portal blood flow and serum albumin parameters are increased, and liver function is unchanged after B‐RTO.

AbstractStatins decrease apoB‐100‐containing lipoproteins by increasing their fractional catabolic rates through LDL receptor‐mediated uptake. Their influence on hepatic secretion of these lipoproteins is controversial. The objective of the study was to examine the influence of simvastatin on the secretion of apoB‐100‐containing lipoproteins in fasting non‐obese subjects. Turnover of apoB‐100‐containing lipoproteins was investigated using stable isotope‐labeled tracers. Multicompartmental modeling was used to derive kinetic parameters. Eight male subjects (BMI 25 ± 3 kg/m2) with mild hypercholesterolemia (LDL cholesterol 135 ± 30 mg/dL) and normal triglycerides (111 ± 44 mg/dL) were examined under no treatment (A), under chronic treatment with simvastatin 40 mg/day (B) and after an acute‐on‐chronic dosage of 80 mg simvastatin under chronic simvastatin treatment (C). Lipoprotein concentrations changed as expected under 40 mg/day simvastatin. Fractional catabolic rates increased in IDL and LDL but not in VLDL fractions versus control [VLDL +35% in B (n.s.) and +21% in C (n.s.); IDL +169% in B (P = 0.08) and +187% in C (P = 0.032); LDL +87% in B (P = 0.025) and +133% in C (P = 0.025)]. Chronic (B) and acute‐on‐chronic simvastatin treatment (C) did not affect lipoprotein production rates [VLDL −8 and −13%, IDL +47 and +38%, and LDL +19 and +30% in B and C, respectively (all comparisons n.s.)]. The data indicate that simvastatin does not influence the secretion of apoB‐100‐containing lipoproteins in non‐obese subjects with near‐normal LDL cholesterol concentrations.

Abstract
A 41 year old woman with a history of colon cancer metastatic to her lung and liver, presented to the emergency department severely dehydrated. Bedside ultrasonography revealed a tumor mass in her proximal inferior vena cava at the junction of the right atrium obstructing the ability to assess her volume status with inferior vena cava inspiratory collapse. Bedside emergency department cardiac tissue Doppler ultrasonography of the lateral right ventricle and pulse Doppler ultrasonography of the tricuspid valve was used to estimate her right atrial pressure and intravascular volume status.
The effects of dating violence, substance use and risky sexual behavior among a diverse sample of Illinois youth

Published: May 2010

ABSTRACTThis study examines the relationship between dating violence, forced sexual intercourse (FSI), and four measures of sexual risk taking (i.e., age at first sex, number of recent (within the last three months) sex partners, alcohol/drug use at last sex, and condom use at last sex) among a sample of 1124 ethnically diverse sexually active adolescents in Illinois. Given conflicting reports regarding the role of gender in dating violence, and the dearth of research examining the role of gender in relations between dating violence, sexual violence, and sexual risk taking, we also examine whether gender moderates the relation between these constructs. The findings indicate significant relationships among dating violence and FSI and age at first sex, number of sexual partners, and condom use across various ethnic groups. Findings also show that when controlling for gender, dating violence and FSI are related to number of sexual partners and age at first intercourse regardless of ethnic group identification.

AbstractQuantitative data of fetal cortical folding and its developmental changes supply important information in the estimation of fetal age and assessment of brain maturation, so the increasing tendencies of cortical growth and its folding conditions at the beginning of the second and third trimesters with post‐mortem Magnetic Resonance Imaging (MRI) were analyzed. 131 fetal specimens of 14–40 weeks gestational age (GA) were selected and scanned with 3.0 T MR. Then the length of folded cortical margin (LFCM) and length of unfolded cortical margin (LUCM) were measured by Photoshop and ZoomMagic software. Degrees of cortical folding (DCF) were calculated by means of (LFCM − LUCM)/LFCM. Growth curves were obtained between the 3 above values and GA, and significant differences in age stages, hemispheres and genders were analyzed. The relationship between LFCM in centimeters, DCF and GA in weeks was described by two exponential growth curves [LFCM = 5.325 exp(0.079GA); DCF = 11.890 exp(0.043GA)]. The curves increased rapidly after 26 weeks GA, which could be recognized as a cut‐off point of fetal cortical and sulcal development. LUCM and GA were described by a logarithmic growth curve which slowed down after 26 weeks GA [LUCM = 30.580 Ln(GA) − 72.490]. Significant differences of the 3 values before and after 26 weeks GA (p < 0.01), but not any in hemispheres and genders were noticed. These results, which may be valuable in assessing normal brain development and can serve as a model in clinical settings, indicate that the cerebral volume first increases and is then followed by increases of the surface area.

Estimation of the glomerular filtration rate (GFR) is a useful tool in the evaluation of kidney function in feline medicine. GFR can be determined by measuring the rate of tracer disappearance from the blood, and although these measurements are generally performed by multi-sampling techniques, simplified methods are more convenient in clinical practice. The optimal times for a simplified sampling strategy with two blood samples (2BS) for GFR measurement in cats using plasma 51chromium ethylene diamine tetra-acetic acid (51Cr-EDTA) clearance were investigated. After intravenous administration of 51Cr-EDTA, seven blood samples were obtained in 46 cats (19 euthyroid and 27 hyperthyroid cats, none with previously diagnosed chronic kidney disease (CKD)). The plasma clearance was then calculated from the seven point blood kinetics (7BS) and used for comparison to define the optimal sampling strategy by correlating different pairs of time points to the reference method. Mean GFR estimation for the reference method was 3.7±2.5 ml/min/kg (mean±standard deviation (SD)). Several pairs of sampling times were highly correlated with this reference method ( r2≥0.980), with the best results when the first sample was taken 30 min after tracer injection and the second sample between 198 and 222 min after injection; or with the first sample at 36 min and the second at 234 or 240 min ( r2 for both combinations=0.984). Because of the similarity of GFR values obtained with the 2BS method in comparison to the values obtained with the 7BS reference method, the simplified method may offer an alternative for GFR estimation. Although a wide range of GFR values was found in the included group of cats, the applicability should be confirmed in cats suspected of renal disease and with confirmed CKD. Furthermore, although no indications of age-related effect were found in this study, a possible influence of age should be included in future studies.
The impact of internal integration and relationship commitment on external integration⋆

AbstractSupply chain integration (SCI) among internal functions within a company, and external trading partners within a supply chain, has received increasing attention from academicians and practitioners in recent years. SCI consists of internal integration of different functions within a company and external integration with trading partners. While both supply chain internal and external integration have been studied extensively, our understanding of what influences SCI and the relationship between internal and external integration is still very limited. This paper argues that external integration with customers and suppliers is simultaneously influenced by internal integration and relationship commitment to customers and suppliers. Internal integration enables external integration because organizations must first develop internal integration capabilities through system‐, data‐, and process‐integration, before they can engage in meaningful external integration. At the same time, before external integration can be successfully implemented, organizations must have a willingness to integrate with external supply chain partners, which is demonstrated by their relationship commitment.We propose and test a model that specifies the relationship between internal integration, relationship commitment, and external integration, using data collected from manufacturing firms in China. The results show that internal integration and relationship commitment improve external integration independently, and their interactive effect on external integration is not significant. However, internal integration has a much greater impact on external integration than relationship commitment.We also examine the model for companies with different ownerships, and the results indicate that for Chinese controlled companies where there is a strong collectivism culture and more reliance on “Guanxi” (relationship), relationship commitment has a significant impact on external integration with suppliers and customers. This is in stark contrast to foreign controlled companies, characterized by a more individualistic culture and more reliance on technological capabilities, where no significant relationship between relationship commitment and external integration could be found. The model is also tested across different industries and different regions in China, providing useful insights for Chinese companies in particular. This study makes significant contributions to the SCI literature by simultaneously studying the effects of internal integration and relationship commitment on external integration, and providing several future research directions.
Maternal serum concentrations of insulin-like growth factor (IGF)-I and IGF binding protein-1 before and during pregnancy in relation to maternal body weight and composition and infant birth weight

Maternal nutritional status, e.g. body weight and composition, is associated with fetal growth. It has been suggested that the insulin-like growth factor (IGF) system may be a mediator of this relationship. In twenty-three healthy Swedish women, we studied (1) the relationships before and during pregnancy between maternal serum concentrations of IGF-I and IGF binding protein-1 (IGFBP-1) and maternal body weight and composition; (2) interactions between serum concentrations of IGF-I (before and in early pregnancy) and maternal nutritional status in relation to infant birth weight. We found that serum IGF-I during pregnancy was positively correlated with maternal body weight (r 0·47–0·56) and fat-free body weight (r 0·61–0·65), whereas serum IGFBP-1 was negatively correlated with maternal body weight (r − 0·44 to − 0·69) and body fat (r − 0·64 to − 0·76) before and during pregnancy. Women with a lower body fat content (%) before pregnancy had greater increases in serum IGFBP-1 during pregnancy than women with a higher prepregnant body fat content (%). In addition, significant fractions of the variation in corrected infant birth weight were explained by variables related to the maternal nutritional status when these were combined with serum concentrations of IGF-I in gestational week 14 (adjusted r2 0·25–0·44, P = 0·001–0·021), but not when they were combined with such concentrations before pregnancy (adjusted r2 0·11–0·12, P = 0·105–0·121). These results suggest mechanisms by which the IGF system may be a mediator between maternal nutritional status and fetal growth.
