GNSS-positioning services like SAPOS/ascos in Germany and many others in Europe, America and worldwide, usually yield in a short time their interdisciplinary and country-wide use for precise geo-referencing, replacing traditional low order geodetic networks. So it becomes necessary that possible changes of the reference stations' coordinates are detected ad hoc. The GNSS-reference-station MONitoring by the KArlsruhe approach and software (MONIKA) are designed for that task. The developments at Karlsruhe University of Applied Sciences in cooperation with the State Survey of Baden-Württemberg are further motivated by a the official resolution of the German state survey departments' association (Arbeitsgemeinschaft der Vermessungsverwaltungen Deutschland (AdV)) 2006 on coordinate monitoring as a quality-control duty of the GNSS-positioning service provider. The presented approach can - besides the coordinate control of GNSS-positioning services - also be used to set up any GNSS-service for the tasks of an area-wide geodynamical and natural disaster-prevention service. The mathematical model of approach, which enables a multivariate and multi-epochal design approach, is based on the GNSS-observations input of the RINEX-data of the GNSS service, followed by fully automatic processing of baselines and/or session, and a near-online setting up of epoch-state vectors and their covariance-matrices in a rigorous 3D network adjustment. In case of large scale and long-term monitoring situations, geodynamical standard trends (datum-drift, plate-movements etc.) are accordingly considered and included in the mathematical model of MONIKA. The coordinate-based deformation monitoring approach, as third step of the stepwise adjustments, is based on the above epoch-state vectors, and - splitting off geodynamics trends - hereby on a multivariate and multi-epochal congruency testing. So far, that no other information exists, all points are assumed as being stable and congruent reference

This article explores the concepts of unmourned and disenfranchised grief as a way to understand the experiences of adult children of Nazi perpetrators, who grew up with cultural norms of grieving alone or in silence. The scholarly literature on descendants of Nazis reflects a group unlikely to warrant empathy or support from others because of the stigma surrounding their family's possible involvement in the Holocaust atrocities. This article uses, as a case study approach, the testimony given by Monika Hertwig, the adult daughter of a high ranking Nazi, who appears in the documentary film, Inheritance. From the perspective of disenfranchised grief, defined as grief that is not socially recognized or supported, the article links Monika's testimony with existing research from in-depth interviews with other descendants of Nazis to suggest that, as a group, they lacked permission to grieve their deceased parents, acknowledgment of their grief, and opportunities to mourn. Based on the theory that the effects of grief can be transgenerational, the disenfranchisement experienced by the "children of the Third Reich" does not have to pass to subsequent generations if opportunities for mourning are made possible and some resolution of grief occurs. Studies have shown that ongoing dialogue groups between Holocaust survivors and descendants of Nazis provide opportunities for mourning to both groups.

The purpose of the present study is to ascertain the effectiveness of familiar additives and oil-soluble inhibitors under conditions of acid corrosion in comparison with their rapid action and waterreplacement efficiency, and the capacity to inhibit an electrolyte that forms in the oils, to protect against electrochemical corrosion, especially from pitting, and to reduce the mechanical-corrosion forms of wear. Characteristics of several oil-soluble corrosion inhibitors and the effectiveness of the oil-soluble inhibitors are shown. The additives M, ALOP, and MONIKA are most effective under fretting-corrosion conditions. It is shown that only the combined additives and compositions that provide for metalmore » protection in both acid and neutral media are sufficiently effective in preventing corrosion cracking, fatigue, corrosion fatigue and corrosion fretting.« less

This paper shows a method to assess the vulnerability of coastal risks such as coastal erosion or submarine applying Fuzzy Analytic Hierarchy Process (FAHP) and spatial analysis techniques with Geographic Information System (GIS). The coast of the Mohammedia located in Morocco was chosen as the study site to implement and validate the proposed framework by applying a GIS-FAHP based methodology. The coastal risk vulnerability mapping follows multi-parametric causative factors as sea level rise, significant wave height, tidal range, coastal erosion, elevation, geomorphology and distance to an urban area. The Fuzzy Analytic Hierarchy Process methodology enables the calculation of corresponding criteria weights. The result shows that the coastline of the Mohammedia is characterized by a moderate, high and very high level of vulnerability to coastal risk. The high vulnerability areas are situated in the east at Monika and Sablette beaches. This technical approach is based on the efficiency of the Geographic Information System tool based on Fuzzy Analytical Hierarchy Process to help decision maker to find optimal strategies to minimize coastal risks.

The goal of the STAR (STrengthening Altitude Research) initiative was to produce a uniform set of key elements for research and reporting in clinical high-altitude (HA) medicine. The STAR initiative was inspired by research on treatment of cardiac arrest, in which the establishment of the Utstein Style, a uniform data reporting protocol, substantially contributed to improving data reporting and subsequently the quality of scientific evidence. The STAR core group used the Delphi method, in which a group of experts reaches a consensus over multiple rounds using a formal method. We selected experts in the field of clinical HA medicine based on their scientific credentials and identified an initial set of parameters for evaluation by the experts. Of 51 experts in HA research who were identified initially, 21 experts completed both rounds. The experts identified 42 key parameters in 5 categories (setting, individual factors, acute mountain sickness and HA cerebral edema, HA pulmonary edema, and treatment) that were considered essential for research and reporting in clinical HA research. An additional 47 supplemental parameters were identified that should be reported depending on the nature of the research. The STAR initiative, using the Delphi method, identified a set of key parameters essential for research and reporting in clinical HA medicine.

Findings suggest age-related, socioeconomic-related, literacy-related, and health-related disparities in the use of mobile technologies. Health app use may reflect a user's motivation to change or maintain health behaviors.

This is probably combine effect of carbonate dissolution associated with relatively slow diffusion of ions though porous coating, affecting both pH and saturation indices. High concentrations of carbonate ions result in CO32- substitution in the structure of precipitating HPY.

An unadjusted between-arm increase of +11.4 was observed on the Picker scale in favor of the intervention arm. Other measures showed negligible changes. Loop was primarily used for medical care management, symptom reporting, and appointment coordination. The results of this study show that implementation of Loop was feasible. It provides useful information for planning future studies further examining effectiveness and team collaboration. Numerically higher scores were observed for the Loop arm relative to the control arm with respect to continuity of care. Future work is required to understand the incentives and barriers to participation so that the implementation of tools like Loop can be optimized.

During mapping (by the Undergraduate Team Research program, University of Southern California) in the Saddlebag Lake pendant just along the eastern margin of the Tuolumne batholith we have discovered a brittle slip component in the ESCSZ that juxtaposes largely metasedimentary and metavolcanic rock packages. The metasedimentary package is dominated by bedded sandstones and siltstones and local conglomerates whereas the metavolcanics show a large range of volcanic and volcaniclastic units. All of the units dip steeply and have an average N-NW strike. Dextral oblique ductile shear is distributed in domains in both rock packages with varying width from ~2 km in the South to ~1 km in the North. Shear sense in planes at high angles to a steep to SW plunging mineral lineation include S-C structures, shear bands, asymmetrical folding, sigma and delta clasts, and asymmetrical boudins. Partitioning of shear is common with the metarhyolites and metasediments showing higher non-coaxial strain than in the metaandesite and metadacite units. Map-scale “z-shaped” asymmetrical folds within the shear zone are also consistent with dextral shearing. Folded and sheared dikes of the 88-85 Ma Cathedral Peak phase of the Tuolumne batholith are common in the shear zone. A newly discovered brittle slip surface with breccias, gouge, and local pseudotachylite and large quartz veins was also mapped in the center of the ductile shear zone typically along the contact between the western metasedimentary and eastern metavolcanics (often a metarhyolite at the contact) on the east. Local slickenlines, steps, and offset dikes indicate that the brittle fault also had oblique dextral movement, similar to the ductile shear zone. In the mapped area no dikes originating from the TB cross the brittle fault and some are terminated at the brittle fault surface We interpret these observations to indicate northward displacement of the metasedimentary package by first ductile then brittle faulting during cooling and possibly uplift of this region with the youngest motion post 82 Ma.

A truly international scholar, Wulff was a member of the Astronomische Gesellschaft, the American Astronomical Society, and a Fellow of the Royal Astronomical Society. Between 1979 and 1985, he served as president of IAU Commission 5 (Documentation and Astronomical Data) and on the executive committee of the International Council on Scientific and Technical. Wulff is survived by Dietlind, his wife of forty-nine years, his daughter Ruth and son Robert, and his two sisters Monika Heintz and Ursula Heintz-Eberlein, who both live in Germany. After having lived a career which was so rich and productive, Wulff will be much missed by the astronomical community, and especially those working in the areas of astrometry and binary stars.

that direct detection and subsequent, effective spectroscopic verification of extra-solar planets is now quite feasible with a ground-based facility like the VLT. It is thus not a very daring prediction that the ongoing searches may soon lead to the first direct images of an extra-solar planet. These are indeed exciting times! More information The work described in this Press Release is discussed by the team in a research article that has been accepted for publication in the European journal Astronomy & Astrophysics. Another paper ( "Direct imaging search for planetary companions next to young nearby stars" ) is also available with more details about the current searches, including the spectrum of the background star at TWA-7. The Principal Investigator for this project may be contacted at: Ralph Neuhaeuser Max-Planck-Institut für Extraterrestrische Physik D-85748 Garching Germany Phone +49-89-32993398 email: rne@mpe.mpg.de Notes [1]: The team consists of Ralph Neuhaeuser (Principal Investigator) and Nuria Huelamo (both Max-Planck-Institut für Extraterrestrische Physik, Garching, Germany), Eike Guenther (Landessternwarte Tautenburg, Germany), Monika Petr (Max-Planck-Institut für Radioastronomie, Bonn, Germany), Wolfgang Brandner (Institute for Astronomy, Honolulu, Hawaii, USA) and João Alves (ESO, Garching, Germany). [2]: The hitherto sharpest image (0.25 arcsec) was obtained in March 1999, cf. ESO PR 06/99. It was obtained during a period of exceptionally good "seeing" (low level of atmospheric turbulence). The installation of adaptive optics at the VLT, foreseen in 2001, will provide a means to overcome the image smearing effect of air turbulence and hence, consistently obtain stellar images of a few hundredths of an arcsecond diameter, near the theoretical limit for an 8.2-m telescope (the telescope diffraction limit ). [3]: 1 solar mass = 2 x 10 30 kg. 1 Jupiter mass = 2 x 10 27 kg ~ 0.001 solar mass. Thus, the "BD-limit" of 0.08 solar masses corresponds to
