Automated data acquisition and reduction system for torsional braid analyzer
Automated Data Acquisition and Reduction System (ADAR) evaluates damping coefficient and relative rigidity by storing four successive peaks of waveform and time period between two successive peaks. Damping coefficient and relative rigidity are then calculated and plotted against temperature or time in real time
Deuterium retention in tungsten and tungsten: tantalum alloys exposed to high-flux deuterium plasmas
A direct comparison of deuterium retention in samples of tungsten and two grades of tungsten-tantalum alloys-W-1% Ta and W-5% Ta, exposed to deuterium plasmas (ion flux similar to 10(24) m(-2) s(-1), ion energy at the biased target similar to 50 eV) at the plasma generator Pilot-PSI was performed using thermal desorption spectroscopy (TDS). No systematic difference in terms of total retention in tungsten and tungsten-tantalum was identified. The measured retention value for each grade did not deviate by more than 24% from the value averaged over the three grades exposed to the same conditions. No additional desorption peaks appeared in the TDS spectra of the W-Ta samples as compared with the W target, indicating that no additional kinds of traps are introduced by the alloying of W with Ta. In the course of the experiment the same samples were exposed to the same plasma conditions several times, and it is demonstrated that samples with the history of prior exposures yield an increase in deuterium retention of up to 130% under the investigated conditions compared with the samples that were not exposed before. We consider this as evidence that exposure of the considered materials to ions with energy below the displacement threshold generates additional traps for deuterium. The positions of the release peaks caused by these traps are similar for W and W-Ta, which indicates that the corresponding traps are of the same kind

Weight loss surgery in adolescents corrects high-density lipoprotein subspecies and their function.
Background/objectiveYouth with obesity have an altered high-density lipoprotein (HDL) subspecies profile characterized by depletion of large apoE-rich HDL particles and an enrichment of small HDL particles. The goal of this study was to test the hypothesis that this atherogenic HDL profile is reversible and that HDL function would improve with metabolic surgery.MethodsSerum samples from adolescent males with severe obesity mean±s.d. age of 17.4±1.6 years were studied at baseline and 1 year following vertical sleeve gastrectomy (VSG). HDL subspecies and HDL function were evaluated pre and post VSG using paired t-tests. A lean group of adolescents was included as a reference group.ResultsAfter VSG, body mass index decreased by 32% and insulin resistance as estimated by homeostatic model assessment of insulin resistance decreased by 75% (both P<0.01). Large apoE-rich HDL subspecies increased following VSG (P<0.01) and approached that of lean adolescents despite participants with considerable residual obesity. In addition, HDL function improved compared with baseline (cholesterol efflux capacity increased by 12%, HDL lipid peroxidation potential decreased by 30% and HDL anti-oxidative capacity improved by 25%, all P<0.01).ConclusionsMetabolic surgery results in a significant improvement in the quantity of large HDL subspecies and HDL function. Our data suggest metabolic surgery may improve cardiovascular risk in adolescents and young adults
Non-invasive blood pressure measurement in the domestic chicken by the use of the Doppler principle
Non-invasive blood pressure measurement by the use of a technique using the Doppler principle allows estimation of systolic blood pressure and heart rate in the conscious bird without trauma. It permits repeated measurements over a long period with minimal stress to the bird. Blood pressure was measured in hypo-, normo-, and hypertensive birds. Measurement using the Doppler principle technique was compared with invasive catheter measurement simultaneously in the same bird

Building school-based social capital through 'We Act - Together for Health' - a quasi-experimental study
Abstract Background Social capital has been found to be positively associated with various health and well-being outcomes amongst children. Less is known about how social capital may be generated and specifically in relation to children in the school setting. Drawing on the social cohesion approach and the democratic health educational methodology IVAC (Investigation – Vision – Action – Change) the aim of this study was to examine the effect of the Health Promoting School intervention ‘We Act – Together for Health’ on children’s cognitive social capital. Method A quasi-experimental controlled pre- and post-intervention study design was conducted with 548 participants (mean age 11.7 years). Cognitive social capital was measured as: horizontal social capital (trust and support in pupils); vertical social capital (trust and support in teachers); and a sense of belonging in the school using questions derived from the Health Behaviour in School Children study. A series of multilevel ordinal logistic regression analyses was performed for each outcome to estimate the effect of the intervention. Result The analyses showed no overall significant effect from the intervention on horizontal social capital or vertical social capital at the six-month follow-up. A negative effect was found on the sense of belonging in the school. Gender and grade appeared to be important for horizontal social capital, while grade was important for sense of belonging in the school. The results are discussed in relation to We Act’s implementation process, our conceptual framework and methodological issues and can be used to direct future research in the field. Conclusion The study finds that child participation in health education can affect the children’s sense of belonging in the school, though without sufficient management support, this may have a negative effect. With low implementation fidelity regarding the Action and Change dimension of the intervention at both the school and class level, and with measurement issues regarding the concept of social capital, more research is needed to establish a firm conclusion on the importance of the children’s active participation as a source for cognitive social capital creation in the school setting.

Pengaruh Faktor-faktor Kebiasaan (Habitus), Modal (Capital), dan Perubahan (Changes) sebagai Model Perilaku Keuangan untuk Meningkatkan Performa Keuangan Perempuan Pelaku UMKM (suatu Studi di UMKM Binaan Fe UNPAR –Bandung dan Jakarta)
Berbagai produk asing tidak dapat dibendung telah menyerbu pasar domestik sekarang. Serbuan tersebut terutama dari barang-barang Cina (Kompas: 2011: 13 Mei h. 38). Fenomena ini telah mengakibatkan munculnya ribuan pengangguran baru. Padahal 90% dunia bisnis Indonesia terdiri dari sektor UMKM (BPS: 2000), dan dari jumlah sektor UMKM tersebut, USAha UMKM yang dikelola oleh perempuan jumlahnya meningkat sangat pesat, hal ini mengindikasikan semakin meningkat pula pemberdayaan perempuan di Indonesia (Kontan: April 2011: h. 11).Berdasarkan analisis kualitatif maka aplikasi teori Bourdieu (1999) dalam penelitian ini dengan tujuan untuk melihat perilaku pengelolaan keuangan oleh perempuan pengelola UMKM, yaitu dari 3 variabel Bourdieu: Habitus, Capital dan Changes, variabel perilaku manakah yang signifikan mempengaruhi performa keuangan UMKM. Variabel dominan akan disosialisasikan kepada perempuan pengelola UMKM lain untuk dianalisis apakah terdapat peningkatan performa keuangannya pada tahun berikutnya, bila perilaku pengelola bertambah baik. Alat analisis statistik akan digunakan sebagai pembanding atas analisis tersebut. UMKM yang diteliti adalah UMKM binaan Unpar.Bila perilaku keuangan perempuan pengelola UMKM bertambah baik, maka performa keuangan USAhanya akan meningkat lebih baik, pada gilirannya diharapkan sektor UMKM akan meningkat kesejahteraannya, serta dapat bertahan menghadapi serbuan produk asing.Kata
