Study on the reliability of an InP/InGaAsP integrated laser modulator

Ridge Integrated Laser Modulator (ILM) devices were fabricated using a butt-coupling technology based on two gas source molecular beam epitaxy. A complete stability evaluation was undertaken, including a reliability study on discrete lasers, discrete modulators and integrated devices. The butt-coupling integration process does not affect the reliability of the integrated devices.     

Fußball-WM und Personalausweisnummer

Die bevorstehende Fu?ball-Weltmeisterschaft besch?ftigt seit einigen Monaten auch die Gerichte. In einem Urteil vom 28. M?rz 2006 hat das AG Frankfurt a.M. die Erhebung und Verwendung der Personalausweisnummer aller Ticket-Bewerber für zul?ssig erkl?rt. Der Beitrag analysiert die Entscheidung und stellt die personalausweisrechtlichen Hintergründe dar.     

Schizophrenic prelingual deaf and hearing patients. A comparison of premorbid and current data after several years of progression

The aim of the present study was to investigate the seroprevalence to Flavivirus, in young people living in risk areas. We analyzed 189 human sera from 3 towns in the Province of Formosa. This area corresponds to the border that limits Brasil and Paraguay and the aim was to search for a possible introduction of Dengue and Yellow Fever from these countries. Serological tests such as haemagglutination inhibition (HI), complement fixation (CF) and neutralization (NT) were performed using St. Louis encephalitis (SLE), Bussuquara, Ilheus, Yellow fever and dengue 1 and 2 viruses. No definite evidence for HI antibodies to dengue and Ilheus was obtained. One serum cross-reacted only with yellow fever and two sera only for Bussuquara by the HI test. Only one serum was confirmed to be positive for Bussuquara by NT test. A total of 22 sera from 189 were positive for SLE by the HI test and 40 were also reactive by the NT test. The seroprevalence measured by HI and NT antibodies was similar in the three departments studied. These results show that SLE virus is present in the North of Argentina with an important value of prevalence so that this agent could play an important role in the febrile infections not virologically confirmed.     

Temperature desensitisation of delay in optical fibres for sensor applications

We demonstrate a significant reduction in delay sensitivity against temperature in optical fibres, using a novel tight jacketed fibre structure. This technique has the cabability of producing fibre in which the optical delay is insensitive to temperature. This has potential in the field of sensors and fibre devices.     

Managing complex data and geometry in parallel structured AMR applications

Adaptive mesh refinement (AMR) is an increasingly important simulation methodology for many science and engineering problems. AMR has the potential to generate highly resolved simulations efficiently by dynamically refining the computational mesh near key numerical solution features. AMR requires more complex numerical algorithms and programming than uniform fixed mesh approaches. Software libraries that provide general AMR functionality can ease these burdens significantly. A major challenge for library developers is to achieve adequate flexibility to meet diverse and evolving application requirements. In this paper, we describe the design of software abstractions for general AMR data management and parallel communication operations in SAMRAI, an object-oriented C++ structured AMR (SAMR) library developed at Lawrence Livermore National Laboratory (LLNL). The SAMRAI infrastructure provides the foundation for a variety of diverse application codes at LLNL and elsewhere. We illustrate SAMRAI functionality by describing how its unique features are used in these codes which employ complex data structures and geometry. We highlight capabilities for moving and deforming meshes, coupling multiple SAMR mesh hierarchies, and immersed and embedded boundary methods for modeling complex geometrical features. We also describe how irregular data structures, such as particles and internal mesh boundaries, may be implemented using SAMRAI tools without excessive application programmer effort. This work was performed under the auspices of the US Department of Energy by University of California Lawrence Livermore National Laboratory under contract number W-7405-Eng-48 and is released under UCRL-JRNL-214559.     

Flaxseed proteins: food uses and health benefits

Flaxseed proteins are potent multi‐functional ingredients for food formulation owing to their techno‐functionalities, food preservation capacity, and health benefits. A possible synergistic effect with mucilage on their functionalities could be valuable even though this co‐product in flaxseed may limit the protein yield during their production processes. Their techno‐functional properties could also be considered in mixture with other flax bioactive components such as lignans and fibre to enhance the value of the flaxseed meal. The present paper reviews flaxseed protein uses in food and their health benefits. New perspectives according to consumers’ demand for products with health promoting bioactive components are also suggested.     

Relationship of management of substance abusers to psychological and practice pattern characteristics of family physicians.

Surveyed 73 family physician alumni from a university/community-based residency program concerning management of substance abuse. This information was related to current practice patterns and to information about the psychological characteristics of the S. The psychological data were acquired during the 1st year of residency training. Findings suggest that family physicians tend to underdiagnose but frequently manage substance abusers. Physicians who are more likely to manage individuals with substance abuse problems include those engaged in solo practice and those who tend to be orderly, introspective, and less anxious and less guilt prone than others. They also tend to be more experientially oriented and less in need of affection, and they place less value on power and on religion. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

"Assessment of environment-therapy systems: The Group Atmosphere Scale": Erratum.

Reports an error in the original article by S. Silbergeld et al(Journal of Consulting & Clinical Psychology, 1975[Aug], Vol 43[4], 460-469). On page 467, the profiles for Figures 1 and 2 were inadvertently reversed. The profiles for Groups C2 and T1 should be placed in Figure 1; those for Groups T1 and TS, in Figure 2. (The following abstract of this article originally appeared in record 1975-28112-001). Describes the Group Atmosphere Scale (GAS) which was developed to measure systematically the psychosocial environment of therapy groups. 12 content subscales, each containing 10 true-false items, assess the consensual psychosocial environment. Several of these serve as indicators of group cohesion and conformity. GAS analyses were based upon data from 149 members of 17 therapy groups. The GAS differentiated among 3 modalities of therapy: academic counseling, long-term psychotherapy, and short-term intervention. Within each treatment modality, the GAS distinguished among different therapy groups. Since identical dimensions have been used to measure psychiatric ward and classroom atmospheres, the GAS makes feasible a comparison of psychosocial environment for diversified milieus.
