Under the Shade of a Coolabah Tree: A Second Cache of Tulas From the Boulia District, Western Queensland

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT This paper reports on the excavation of a cache of stone artefacts, buried on the bank of a waterhole or ‘billabong’ in central western Queensland. This is an extremely rare find, and yet it is the second such site to be reported within less than a 10 km radius.

Atmospheric CO2 consumption by continental erosion : present-day controls and implications for the last glacial maximum [PDF]

open access: yes, 1998
The export of carbon from land to sea by rivers represents a major link in the global carbon cycle. For all principal carbon forms, the main factors that control the present-day fluxes at the global scale have been determined in order to establish global

Repeating Nuclear Transients From Repeating Partial Tidal Disruption Events

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT Extragalactic nuclear transients that exhibit repeating outbursts can be modeled as the repeated dynamical interaction between bound stars and supermassive black holes (SMBHs). A subset of these transients, with recurrence timescales of months‐to‐years, have been explained as accretion flares from the repeated tidal stripping of a star by an ...

Impacts of climate change and human activities on sediment load in Longchuan River Basin, China

open access: yesJournal of Hydrology: Regional Studies
Study region: Longchuan River Basin in the Hengduan mountain region, China. Study focus: With the decrease in annual precipitation, the sediment yield on the slope and sediment delivery ratio (SDR) in the river channel, both play a critical role in ...

Beyond peak reservoir storage? A global estimate of declining water storage capacity in large reservoirs [PDF]

open access: yes, 2013
Water storage is an important way to cope with temporal variation in water supply and demand. The storage capacity and the lifetime of water storage reservoirs can be significantly reduced by the inflow of sediments.

Discrete Element Method Modeling of an Extrusion Process with Recirculation for Dry Manufacturing of Lithium‐Ion Battery Electrodes

open access: yesBatteries &Supercaps, EarlyView.
On a digitized laboratory extruder, discrete element method modelling is studied, considering two classes of particles representing aggregates of 1) active material and 2) binder and carbon material is studied. Various extrusion scenarios leading to the formation of filaments devoted to the 3D printing of lithium‐ion battery electrodes are studied. The

Effect of Rainfall Pattern on Sediment Yield and Runoff in Different Textured Soils

open access: yesPolytechnic Journal
Evaluating the impacts of rainfall intensities on bulk density, runoff rate, and sediment yield is critical in soil characterization and sediment transport. The primary objective of this research is to use multiple linear regression analysis to establish

Evaluation of the utility of sediment data in NASQAN (National Stream Quality Accounting Network) [PDF]

open access: yes, 1983
Monthly suspended sediment discharge measurements, made by the USGS as part of the National Stream Quality Accounting Network (NASQAN), are analysed to assess the adequacy in terms of spatial coverage, temporal sampling frequency, accuracy of ...

Simulated Runoff and Sediment Yield Responses to Land-Use Change Using the SWAT Model in Northeast China

open access: yesWater, 2019
Land-use change is one key factor influencing the hydrological process. In this study, the Hun River Basin (HRB) (7919 km2), a typical alpine region with only four gauge meteorological stations, was selected as the study area.
