The present study deals with new material of carnivorans (Mustelidae, Mephitidae, Ailuridae, Potamotheriinae and Viverridae) from the basal Tortonian (Late Miocene, late Astaracian) hominid-bearing locality of Hammerschmiede (Bavaria, Germany). The small carnivoran fauna includes 20 species belonging to nine different subfamilies (Guloninae, Lutrinae, Mellivorinae, Potamotheriinae, Leptarctinae, Mephitinae, Simocyoninae, Genettinae and Viverrinae). The identified forms include: "Martes" sansaniensis, "Martes" cf. munki, "Martes" sp., Circamustela hartmanni n. sp., Laphyctis mustelinus, Guloninae indet., Eomellivora moralesi, Vishnuonyx neptuni, Paralutra jaegeri, Lartetictis cf. dubia, Trocharion albanense, Palaeomeles pachecoi, Proputorius sansaniensis, Proputorius pusillus, Alopecocyon goeriachensis, Simocyoninae indet., Potamotherium sp., Semigenetta sansaniensis, Semigenetta grandis and Viverrictis modica. The new species Circamustela hartmanni n. sp. is differentiated from the other members of the genus by its small size and the morphology of its dental cusps in the upper and lower carnassials. This is one of the highest reported taxonomic diversities for fossil small carnivorans in the Miocene of Europe, including also first and last occurrences for several genera and species. Additionally, the assemblage comprises some rare taxa such as Palaeomeles pachecoi and Eomellivora moralesi. An ecomorphological comparison of the discovered taxa reveals possible cases of competition and niche partitioning.

There are currently many large-field surveys operational and planned including the powerful Vera Rubin Observatory Legacy Survey for Space and Time (LSST). These surveys will increase the number and diversity of transients dramatically. However, for some transients, like supernovae (SNe), we can gain more understanding by directed observations than by simply increasing the sample size. For example, the initial emission from these transients can be a powerful probe of these explosions. Upcoming ground-based detectors are not ideally suited to observe the initial emission (shock emergence) of these transients. These observations require a large field-of-view X-ray mission with a UV follow up within the first hour of the event. The emission in the first one hour to even one day provides strong constraints on the stellar radius and asymmetries in the outer layers of stars, the properties of the circumstellar medium (e.g. inhomogeneities in the wind for core-collapse SNe, accreting companion in thermonuclear SNe), and the transition region between these two. This paper describes a simulation for the number of SNe that could be seen by a large field of view lobster eye X-ray and UV observatory., Comment: 13 pages, 7 figures, submitted to ApJ

This report provides an overview about recent research activities and current practice concerning inspection and monitoring of the structural performance of bridges and the related decision-making process. A brief review of common methods of collecting information on structural performance of bridges is presented, followed by a description of the use of the information collected in structural analysis and maintenance planning. An overview about the state of the art is given including recent scientific developments. Finally, the current Swedish practice for bridge management is presented.

Ultrahochfester Beton (UHPC) erlaubt aufgrund seiner hohen Festigkeit und extrem dichten Matrix die Konstruktion von sehr filigranen Bauteilen. Dies gilt auch für Verbundträger mit externer Bewehrung, bei denen der Stahlflansch als reines Zugglied außerhalb des Betons liegt. Die schubfeste Verbindung zwischen der externen Bewehrung und dem dünnen UHPC-Steg erfolgt über Verbunddübelleisten, die in diesem Fall nur eine sehr geringe seitliche Betondeckung besitzen. Im Rahmen der vorliegenden Arbeit wurden basierend auf experimentellen und numerischen Untersuchungen von Push Out Körpern und Verbundträgern die erforderlichen Konstruktionsprinzipien und Bemessungsregeln zur Anwendung von Verbunddübelleisten in diesen schlanken und hochtragfähigen Verbundträgern aus UHPC entwickelt., Due to its high compressive strength and extremely dense microstructure, Ultra-High Performance Concrete (UHPC) allows the design and construction of very light-weight, slender structural members. This also applies to composite beams with so-called external reinforcement, where the steel flange on the underside of the concrete section acts solely as a tension member. The longitudinal shear between the external reinforcement and the thin UHPC web is carried by composite dowels with very low concrete cover. Based on the results of experimental and numerical investigations on push out specimens and composite beams, design and construction guidelines for the application of composite dowels in slender composite beams with thin UHPC webs have been developed, as presented in this thesis.

The present paper provides some ideas about how decisions concerning maintenance of timber bridges should be made in a rational way. First, a brief discussion is provided concerning the evolution of maintenance strategies in general and it is suggested that maintenance of timber bridges should follow a risk-based approach. Then the discussion moves on to the condition assessment of timber bridges with a main focus on inspection and monitoring. The use of non-destructive testing methods and structural health monitoring is highlighted with regard to collecting useful information for maintenance decisions. It is argued that the information collected, should be used in a Bayesian decision analysis framework, which is especially useful in quantifying to value of information and thus the worth of various inspection and monitoring alternatives., BIG BRO - Beslutsstöd för rationellt underhåll och uppgradering av befintlig infrastruktur baserat på avancerade utvärderingsmetoder, mätningar och övervakning, COST Action TU1402

Slitsmurar har, i svenska infrastrukturprojekt, hittills enbart använts som temporära stödkonstruktioner under byggnationen. Sedan 2007, tillåter dock Trafikverket att slitsmurar används som en del av en permanent konstruktion. I denna rapport presenteras normutvecklingen, nationellt och internationellt, under de senaste tio åren samt erfarenheter från nordiska slitsmursprojekt under samma period sammanfattas. För att stimulera innovation och rationella val av produktionsmetod strävar Trafikverket efter att upphandla entreprenader baserat på funktionskrav i stället för att föreskriva tekniska lösningar. I rapporten diskuteras funktionskrav ur ett slitsmursperspektiv, samt problematiken kring hur de kan verifieras. Hittills har slitsmurar bara uppfört i ett fåtal projekt i Sverige. I två större infrastrukturprojekt har slitsmurar utnyttjats som temporära stödkonstruktioner. Inom två andra närtida projekt, ett husprojekt samt ett värmeverk, används slitsmurar som en del av den permanenta konstruktionen. Erfarenheter från dessa projekt kan utnyttjas vid användning av permanenta slitsmurar i kommande infrastrukturprojekt. Flera uppdateringar av normer och standarder har gjorts som berör konstruktion och utförande av slitsmurar. Störst praktisk konsekvens bör Trafikverkets accepterande av slitsmurar i permanenta konstruktioner få. Nationella standarder hänvisar till SS-EN 1538 (SIS, 2010). Uppdatering av denna standard gjordes 2010 i form av en relativt omfattande omarbetning. Den uppdaterade standarden ger en bättre bas för slitsmurskonstruktioner då många avsnitt blivit utökade och förtydligade. Sammanfattningsvis uppvisar de slitsmurar som uppförts, både i infrastruktur- samt husprojekt, tillfredställande resultat. Normer har utvecklats mot tydligare krav under det senaste decenniet vilket bör förenkla så väl upphandling som uppförhandet av slitsmurar., Slitsmurar som permanenta konstruktioner – en uppföljning
