Recent efforts to increase online privacy by offering the user a more general choice to opt out of online tracking were mainly pushed by the FTC in late 2010. As the FTC explicitly omitted technical details, browser developers started to implement what they thought might be appropriate to either limit user tracking directly, or let the advertiser know about the user’s wish to not be tracked. Th...

Abstract Chalcopyrite (CuFeS 2 ) is the most refractory copper mineral when treated in conventional sulfate media leaching systems. This first study to examine use of a dimethyl sulfoxide (CH 3 SOCH , DMSO) solution containing chloride (CuCl for chalcopyrite. Leaching experiments concentrate composed mainly chalcopyrite were conducted at ambient pressure 313–413 K. The fractions Cu, Fe, S, Au, ...

2. Do I hold in my hand the truly appropriate remedy for that lack ? 3. Is the preparation stable, active, pure, and uniform ? 4. Can I accurately determine the dosage ? 5. Is the preparation smoothly active when administered by the route I propose ? 6. Are ill-effects impossible ? Even if these questions cannot be answered in the affirmative, he gives the prescriber one more chance, provided t...

OBJECTIVE To stimulate and awakening the interest of students of high school or elementary public schools in research and science through scientific initiation stages in the Postgraduate Program in Translational Surgery.

In order to explain how DIYbio knowledge and expertise is developed and shared the use of Practice Theory will help us gain a useful understanding of how working practices are sustained, reproduced and potentially changed. In addition, the development and sharing of thick, evocative, rich descriptions of these practices might contribute to the motivational knowledge of DIYbio practitioners.

DO-178B was based on the consensus of the avionic software community as it existed in 1992. Twenty two years after publication, we have no publically available experimental data as to its efficacy. It appears to work extremely well, since there have been no hull loss accidents in passenger service ascribed to software failure. This is a comforting and surprising result. However, if we don’t kno...

One key step in the development of safety-critical applications is the assessment of the quality of the verification strategy. In practice, structural coverage is the methodology used to ascertain the testing campaign well satisfy a given quality criteria. In this paper, we describe the possible strategies to measure structural coverage in a DO-178B context. After evaluating state-ofthe-art app...

Nitrogen-filled “Vacutainers” (Becton-Dickinson, Rutherford, N. J. 07070) have been proposed for the anaerobic collection of specimens for blood gas determinations (1). We have indicated (2) that these devices, as currently supplied by the manufacturer, contain oxygen and may produce spuriously high P(02) and percentage oxyhemogobin (HbO) values. We had previously indicated preference for the u...

Content objects are essential links between Knowledge Management and E-Learning systems. Therefore content authoring and sharing is an important, interdisciplinary topic in the resp. fields. In this paper, we want to critically elaborate on the “user as producer and consumer”-concept for content production and consumption. We address the subject by using the notion of content collaboration as e...

OBJECTIVE To measure the delivered fractional oxygen concentration (F(DO(2))) from preterm-size Laerdal silicone resuscitators (PLSR) without a reservoir. BACKGROUND The North American Neonatal Resuscitation Program manual states that self-inflating bags without a reservoir deliver approximately 40% oxygen, differing from the PLSR manufacturer's specifications. METHODS A neonatal test lung ...
