Diversity requirements for safety critical software-based automation systems. System vendors nowadays propose software-based systems even for the most critical safety functions in nuclear power plants. Due to the nature and mechanisms of influence of software faults new methods are needed for the safety and reliability evaluation of these systems. In the research project 'Programmable automation systems in nuclear power plants OHA ' various safety assessment methods and tools for software based systems are developed and evaluated.

A Cafe Scientifique for Teens. It is well-known to those pursuing the quest to connect scientists to the public that an exceedingly hard-to- reach demographic is people of high school age.
Typically, kids may tag along with their parents to museums until they reach adolescence, and then don't again appear in museums until they themselves have children. We have addressed this demographic challenge for free-choice-learning by developing a Cafe Scientifique program specifically for high school students. The Cafe Scientifique model for adults was developed in England and France, and has now spread like wildfire across the U.
Typically, people come to a informal setting like a cafe, socialize and have food and drink, and then hear a short presentation by a scientist on a hot science topic in the news.
This is followed by a period of lively discussion. We have followed this model for high school age students in four towns in northern New Mexico--Los Alamos, Santa Fe, Espanola, and Albuquerque--which represent a highly diverse demographic. We started this novel project with some trepidation, i. But the program has proven popular beyond our expectations in all four towns. A part of the secret of success is the social setting, and-especially for this age group-the food provided.
But we have also found that the kids are genuinely interested in the science topics, directing their own program, and interacting with scientists. We have often heard statements like, "I think it is important to be well-informed citizens". One of the most important aspects of the Cafes for the kids is to be able to discuss and argue about issues related to the science topic with the presenter and each other.
It is an important part of the popularity that the Cafes do not involve school or parents, but also that we have strived to give the kids ownership of the program. Each town has a Youth Leadership Team-open to any teen-that discusses and prioritizes potential topics, conducts. Recollections of the author's early experiences in French family planning and reflections on the ethical issues and legal status of new fertility technologies are the major topics of this address. The group that was to become le Mouvement francais pour le Planning Familial MFPF was founded in by the author and others and opened its first family planning center in , before contraception became legal.
Despite opposition from physicians and Catholic clergy, the MFPF operated centers serving over , clients by In the MFPF began a study of abortion. Despite legalization, the controversy concerning the legitimacy of abortion has not subsided. More recently, the practices of artificial insemination with donor sperm, in vitro fertilization, surrogate mothers, and other medically assisted fertility technologies have raised moral, ethical, and legal questions for all societies.
The questions range from the legitimacy of gamete donation to the status of unused embryos. The dissociation of different stages of the reproductive process affects concepts of filiation, paternity and maternity. In the absence of appropriate legislation, it has been left largely to the courts to create a new body of law at this frontier.
The review of legislation in France, elsewhere in Europe, and in the U. It would be highly desirable for the European countries to adopt a common legislation in these areas. Des journees d'etudes sur les techniques d'expression Days of Study on Expression Techniques.

Discussion centered around the role of linguistics, of the media, and of psychological factors. Text is in French. Plus de connaissances et de preuves scientifiques. PubMed Central. We have modified the popular Cafe Scientifique model for engaging adults in dialog on issues at the nexus of science and society to address the specific needs and interests of high-school age youth.
Key elements of the model are Youth Leadership Teams that guide the program design and assist with implementation; a speaker preparation process to…. Processing of special formats diagrams, tables - Determination of words to be Pre-analysis Programs added to system dictionary Dictionary The monolingual lexi- Unfortunately, there is at present no linguistic theory which cons.
We have created an informal science program that engages high school age youth in exploring science relevant to their lives with researchers working at the cutting edge of science. The program provides scientists a challenging new audience to share their research and enthusiasm for science and science careers. It gives the youth an opportunity to discover how the often-mundane science they are learning in school is used to push the frontiers in science, with exciting applications in the real world.
We feature short presentations with a high degree of interactivity and discussion during which the scientist expert communicates a single important idea or scientific principle. A good speaker will leave the audience with a dilemma or controversy to discuss, and with further opportunities to learn. Encouraging the presenters to interact frequently with the audience allows them to gauge the audience's engagement and knowledge.
Controversial topics are often presented within a scientific, economic, and social or political framework, because science is only part of the solution. A key element of success is in preparing the presenters for the youth audience.
Presenters submit their presentation to the program directors for initial review and receive feedback on length, mechanisms for involving the audience, and clarifying or. Le point sur les amas de galaxies. Fires Burning near Big Sur , California. Fires near Big Sur , Calif. Pockmarks off Big Sur , California. A pockmark field was discovered during EM multi-beam bathymetric surveys on the lower continental slope off the Big Sur coast of California. The field contains???
To investigate the origin of these features, piston cores were collected from both the interior and the flanks of the pockmarks, and remotely operated vehicle observation ROV video and sampling transects were conducted which passed through 19 of the pockmarks.
The water column within and above the pockmarks was sampled for methane concentration. Piston cores and ROV collected push cores show that the pockmark field is composed of monotonous fine silts and clays and the cores within the pockmarks are indistinguishable from those outside the pockmarks.
No evidence for either sediment winnowing or diagenetic alteration suggestive of fluid venting was obtained. Concentrations of methane, dissolved inorganic carbon, sulfate, chloride, and ammonium in pore water extracted from within the cores are generally similar in composition to seawater and show little change with depth, suggesting low biogeochemical activity.
These pore water chemical gradients indicate that neither significant accumulations of gas are likely to exist in the shallow subsurface??? Taken together the data indicate that these pockmarks are more than yr old, are presently inactive, and contain no indications of earlier fluid or gas venting events. All rights reserved.

Croissance epitaxiale de GaAs sur substrats de Ge par epitaxie par faisceaux chimiques. Les resultats de caracterisation indiquent que les materiaux obtenus presentent une tres faible rugosite de surface, une bonne qualite cristalline et un dopage residuel relativement important. Finalement, la diffusion d'arsenic dans le substrat de germanium est comparable aux valeurs trouvees dans la litterature pour la croissance a basse temperature avec les autres procedes d'epitaxie courants.
Ces resultats confirment que la technique d'epitaxie par faisceaux chimiques CBE permet de produire des couches de GaAs sur Ge de qualite adequate pour la fabrication de cellules solaires a haute performance. L'apport a la communaute scientifique a ete maximise par le biais de la redaction d'un article soumis a la revue Journal of Crystal Growth et la presentation des travaux a la conference Photovoltaics Canada Planned in by the French protectorate of Morocco, this institute has played, since its effective creation in , an important role in the development of several geosciences in North Africa, such as meteorology and climatology, geophysics gravimetry, magnetism and especially seismology , geomorphology, geology and oceanography.
After the independence of Morocco in , several activities, such as meteorology, were transferred elsewhere, but others, such as seismology and magnetism, remained important elements of the centre until recent years. In addition to the research activities, its observatories and libraries that were built during the early years are unique in Northwest Africa. Adolescence et pornographie sur la toile.

In Northern California alone, fires have consumed more than , acres. At least 18, people have deployed to attempt to extinguish or control the flames. Air quality as far away as San Francisco has been adversely impacted by the dense clouds of smoke and ash blowing towards the northwest. The satellite image combines a natural color portrayal of the landscape with thermal infrared data showing the active burning areas in red. The dark area in the lower right is a previous forest fire.
A joint U. The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping, and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance.
The U. Size: ATP-sensitive potassium channels K-ATP channels play a key role in adjusting the membrane potential to the metabolic state of cells. SUR modulates channel gating in response to the binding of nucleotides or drugs and Kir6. The activity of K-ATP channels varies with their localization. Three residues E, I, L located in the linker region between transmembrane domain 2 and nucleotide-binding domain 2 of SUR 2A were previously found to be involved in the activation pathway linking binding of openers onto SUR 2A and channel opening.
This article details a faculty learning community FLC that started in on the campus of a Midwestern University and has evolved into an interdisciplinary research, teaching and social community of practice and learning called Sur PriSe. We analyzed the biotic, abiotic, and human components interacting at the coastal zone of the Ojo de Liebre Lagoon, Baja California Sur , Mexico.
