DXYS156: a multi-purpose short tandem repeat locus for determination of sex, paternal and maternal geographic origins and DNA fingerprinting
2002
In forensic science and in legal medicine Y chromosomal typing is indispensable for sex determination, for paternity testing in the absence of the father and for distinguishing males in multiple rape cases. Another potential application is the estimation of paternal geographic origin or family name from a crime stain to narrow down the range of suspects and thus reduce costs of mass screenings. However, Y typing alone cannot provide a sufficiently resolved DNA fingerprint as required for court convictions. Thus, there is a dilemma whether or not to sacrifice valuable material for the sake of extensive Y chromosomal investigations when stain DNA is limited (typically allowing only few PCR am…
Psychological distress of children with early-onset type 1 diabetes and their mothers' well-being
2015
Aim Few studies have focused on the psychological adjustment of pre-adolescent children with type 1 diabetes. This study examined psychosocial functioning in nine- and 10-year-old children with early-onset type 1 diabetes, and their mothers, and associations between psychosocial functioning and diabetes management. Methods The mothers of 63 children with early-onset diabetes and 86 healthy children evaluated their own psychosocial functioning, and their child's, with standardised rating scales. We used general linear models to analyse the children's behaviour problems and the mothers' well-being. Associations between the children's behaviour problems, diabetes-related measures and the mothe…
Depression, Somatization, and Posttraumatic Stress Disorder in Children Born of Occupation After World War II in Comparison With a General Population.
2015
At the end of World War II and during the first decade after the war, roughly 200,000 children were fathered in intimate contacts between German women and foreign soldiers. The experiences of these German occupation children (GOC) have been so far described in case reports and from historical perspective only. Research on psychosocial consequences of growing up as a GOC has been missing so far. This study examined traumatic experiences, posttraumatic stress disorder, somatization, and depression in GOC (N = 146) using self-report instruments: Posttraumatic Diagnostic Scale and Patient Health Questionnaire. Findings have then been compared with a representative birth cohort-matched sample fr…
Electrical characterization of highefficiency bifacial silicon solar cells
2018
This work presents a preliminary study on the electrical characterization of high efficiency bifacial solar cells. An opening discussion on the state-of-the-art of such advanced technology is initially proposed and the experimental characterization of some prototypes is described. From this analysis, it can be stated that the bifacial silicon solar cells can be a very promising technology with high electrical performances and efficiency.
Influence of oblique edge blanking on the online punching quality after stretch bending
2018
The oblique edge punching was proposed to reduce the surrounding sag failure occurred under the large punching force during online punching after stretch bending. The finite element models under three different kinds of punches were stablished and the punching processes were simulated by using the DEFORM-3D software. Comparison between the flat-edge punch and the oblique edge punches were realized, and the optimal height of the oblique edge of the unilateral bevelled punch and the single-peak bevelled punch were obtained. Three kinds of punches were designed based on the simulation results, and the experiments for manufacturing the upper strip of the automobile door frame by the online punc…
Optical Probing (EOFM/TRI): A large set of complementary applications for ultimate VLSI
2013
International audience; Electro Optical Techniques (EOFM: Electro Optical Frequency Mapping and EOP: Electro Optical Probing) and Dynamic Light Emission Techniques (TRE: Time Resolved Emission and TRI: Time Resolved Imaging) are dynamic optical probing techniques widely used at IC level for design debug and defect localization purpose. They can pinpoint the origin of timing issue or logic fault in up to date CMOS devices. Each technique has its advantages and its drawbacks allowing a common set of applications and more specific ones. We have been involved in the development of the most advanced techniques related to EOFM and TRI on various devices (down to 28nm technology). What we can expe…
Regarding Quality Management System in Aerospace Industry Organizations
2019
This paper illustrate the quality management system in an organization with field of activities in manufacturing of aerospace components. The aerospace standard of quality management system is EN AS 9100, based on ISO 9001. Additional to the EN AS 9100 quality management system standard requirements, the organizations in aerospace field, need to integrate in their quality system a lot of additional process and regulations specific in aerospace industry. The big aircraft producers have designed their requirements in such a way that all approved suppliers, which are respecting these requirements, can manufacture high quality products. These requirements are manufacturing process specification…
Mesoscopic structural organization in fluorinated pyrrolidinium-based room temperature ionic liquids
2019
Abstract In this contribution the microscopic and mesoscopic structural organization in a series of fluorinated room temperature ionic liquids, based on N-methyl-N-alkylpyrrolidinium cations and on bis(perfluoroalkylsulfonyl)imide anions, is investigated, using a synergy of experimental (X-ray and neutron scattering) and computational (Molecular Dynamics) techniques. The proposed ionic liquids are of high interest as electrolyte media for lithium battery applications. Together with information on their good ion transport properties in conjunction with low viscosity, we also describe the existence of nm-scale spatial organization induced by the segregation of fluorous moieties into domains. …
Stabilizing organic photocathodes by low-temperature atomic layer deposition of TiO2
2017
Organic semiconductor light absorbers are receiving attention for their potential application in photoelectrochemical (PEC) cells for renewable fuels generation. Key to their advancement is precise control of the interfaces between charge-selective contacts, absorber layers, and electrocatalysts, while maintaining compatibility with an aqueous electrolyte environment. Here we demonstrate a new process for low-temperature atomic layer deposition (ALD) of TiO2 onto a P3HT:PCBM polymer blend surface for stable high-performance organic PEC photocathodes. This ALD TiO2 layer provides three key functions: (1) formation of an electron-selective contact to the polymer to enable photovoltage and pho…
Microscopic structural and dynamic features in triphilic room temperature ionic liquids
2019
Here we report a thorough investigation of the microscopic and mesoscopic structural organization in a series of triphilic fluorinated room temperature ionic liquids, namely [1-alkyl, 3-methylimidazolium][(trifluoromethanesulfonyl)(nonafluorobutylsulfonyl)imide], with alkyl=ethyl, butyl, octyl ([C(n)mim][IM14], n = 2, 4, 8), based on the synergic exploitation of X-ray and Neutron Scattering and Molecular Dynamics simulations. This study reveals the strong complementarity between X-ray/neutron scattering in detecting the complex segregated morphology in these systems at mesoscopic spatial scales. The use of MD simulations delivering a very good agreement with experimental data allows us to g…
