ABSTRACT National Aeronautics and Space Administration’s Interior Exploration using Seismic Investigations, Geodesy, Heat Transport (InSight) mission on Mars continues to record seismic data over 3 yr after landing, a thousand marsquakes have been identified, date. With only single station, the determination of epicentral location is far more challenging than Earth. The Marsquake Service (MQS) ...

Given the threats to regional river ecological flow, including sharp increase in per capita water demand, number of hydraulic engineering, and strong seasonal runoff rainfall recharge channels, we clarified appropriate flow thresholds for middle reaches Bailong River northwest China. Based on monthly data Wudu Hydrological Station from 1990 2020, seven suitable hydrological methods were used co...

Under climate change, river ecological base flow becomes particularly critical for the health and stability of inland ecosystems in arid regions. Taking three typical seasonal rivers, including Kriya River, Niya Qarqan all on northern slope Kunlun Mountains, as research objects, meteorological data from 1958 to 2019 hydrological 1978 2014 were selected analyze characteristics under change. The ...

Ecological flows in rivers are critical to the health and stability of river ecosystems, especially for inland drylands where ecological conditions rapidly deteriorating. Climate change human activities lead hydrological variation, which turn alters balance local ecosystems. Therefore, it is important study flow under variation. In this study, second-largest basin China, Hei River Basin, was se...

Abstract Failure in Environmental flow quantity, timing, and quality leads to failure support ecosystems, human livelihoods, well-being. Irrigation water use is one of the main actors impacting rivers quantity time but was not well investigated many ungauged catchments under smallholder irrigation systems. This study examined impact on environmental Arata's small catchment. The estimated sub-ca...

Read and Neil Tennant for helpful comments and discussions on topics related to this work. Drafts of Chapters 5 and 6 were written during a research stay at the Department of Logic and Metaphysics of the University of St. Andrews in Spring 1985. I am grateful to the Fritz Thyssen Stiftung for supporting this stay with a travel grant. I should like to thank my colleagues, especially Gereon Wolte...

BACKGROUND The Royal Flying Doctor Service (RFDS) provides aeromedical care to patients during fixed-wing transport over vast distances to healthcare unavailable in rural or remote communities. This study examined the relationship between changes in local accessibility to primary healthcare services and rates of aeromedical service use over time. METHODS This was a 13-year interrupted time-se...
