No Time to Waste: A Synthesis of Evidence on Time Reallocation Following Water, Sanitation and Hygiene Interventions

Journal of International Development, EarlyView.
ABSTRACT Large amounts of time are wasted globally accessing water for domestic uses and sanitation, disproportionately impacting women and girls. We conducted a systematic review and meta‐analysis based on evidence mapping initiatives. Our synthesis of the evidence found a mean reduction of 15 min per trip for water supply interventions, and 3 min per

SZ–X-Ray Surface Brightness Fluctuations in the SPT-XMM Clusters

The Astrophysical Journal
The hot plasma in galaxy clusters, the intracluster medium, is expected to be shaped by subsonic turbulent motions, which are key for heating, cooling, and transport mechanisms.

Distribution and Evolution of Metals in the Magneticum Simulations

Galaxies, 2017
Metals are ideal tracers of the baryonic cycle within halos. Their composition is a fossil record connecting the evolution of the various stellar components of galaxies to the interaction with the environment by in- and out-flows.

An aminostratigraphy of the northern Upper Rhine Graben, Germany

Journal of Quaternary Science, EarlyView.
ABSTRACT The northern Upper Rhine Graben (Germany) contains a complex, quasi‐continuous Quaternary record, but constraining its chronology is challenging. This study presents the first application of amino acid geochronology for this region using Bithynia opercula to establish a relative dating framework.

Broad Band Optical Polarimetric Study of IC 1805 [PDF]

, 2007
We present the BVR broad band polarimetric observations of 51 stars belonging to the young open cluster IC 1805. Along with the photometric data from the literature we have modeled and subtracted the foreground dust contribution from the maximum ...

IDLB: An SDN‐Based Load‐Balancing Routing Protocol for Autonomous Satellite Constellation Networks

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Routing in satellite constellation networks with intersatellite links has become an important aspect to enable broadband Internet access and to integrate into terrestrial networks. However, their dynamic characteristics and large physical size require specifically tailored solutions.

A holistic view on ram pressure stripping in the Virgo cluster - The first complete model-based time sequence

, 2009
Based on a comparison of dynamical models with observations of the interstellar gas in 6 Virgo cluster spiral galaxies a first complete ram pressure stripping time sequence has been established.

A Generative Model for Realistic Galaxy Cluster X-Ray Morphologies

The Astrophysical Journal
The X-ray morphologies of clusters of galaxies display significant variations, reflecting their dynamical histories and the nonlinear dependence of X-ray emissivity on the density of the intracluster gas. Qualitative and quantitative assessments of X-ray

Separation Maps for Classification of Multiple Partial Discharges: A Comparative Study Focusing on Time and Frequency Characteristics

High Voltage, EarlyView.
ABSTRACT Electrical insulation faults produce partial discharges (PD), which can be analysed to identify specific types of defects. PD clustering is a widely used method to identify PD sources, although its success depends largely on the feature maps used.

Intracluster stellar population properties from N-body cosmological simulations -- I. Constraints at $z=0$

, 2003
We use a high resolution collisionless simulation of a Virgo--like cluster in a $\Lambda$CDM cosmology to determine the velocity and clustering properties of the diffuse stellar component in the intracluster region at the present epoch.
