Large amounts of energy storage are required to support high levels solar and wind power. Pumped hydro comprises the majority global for electricity industry. A previous study identified 616,000 potential "Greenfield" closed-loop (off-river) pumped sites around world with combined 23,000 Terawatt-hours (TWh). In this study, we identify 904 in mining areas ("Brownfield") 30 TWh. spatial resolution atlas Brownfield systems is available online. It was developed through Geographic Information...

Three-quarters of the global population lives in sunbelt region (±35o latitude) with excellent access to solar resources. Wind resources at equator are very limited, while supply chain and permitting delays slowing wind deployment a scale. This paper investigates potential for photovoltaic-dominant 100% renewable grids be developed countries through case study Malaysia. It was expected that technical photovoltaics off-river pumped hydro would far excess what is required decarbonise...

The authors used a lexical-decision task in 3 different experiments to examine whether age differences word recognition were consistent across processing stage. In all experiments, frequency and length manipulated. Experiments 1 2, encoding difficulty was varied, Experiment 3, response selection varied. there no for frequency. However, older adults showed larger decrement encoding. when load increased. These results suggest that occur because exhibit primarily peripheral-rather than...

S. P. Vecera and M. J. Farah (1994) have addressed the issue of whether visual attention selects objects or locations. They obtained data that they interpreted as evidence for attentional selection from an internal spatially invariant representation. A. F. Kramer, T. Weber, E. Watson question this interpretation on both theoretical empirical grounds. First, authors suggest there are other interpretations consistent with location-mediated objects. Second, provide data, using displays employed...

The authors report 4 lexical decision experiments in which case type, word frequency, and exposure duration were varied. These data indicated that there is a larger mixed-case disadvantage for nonwords than words longer presentations of targets. However, when targets presented 100 ms (followed by postdisplay pattern mask), occurred nonwords. For the from Experiments 1, 2, 3 revealed slightly mixed- higher frequency lower words. (There was additivity between type experiment 4.) results are...

Abstract The rapidly growing scale of solar photovoltaics and wind energy coupled with electrification transport, heating industry offers an affordable pathway for achieving deep decarbonization. Massive integration variable requires large-scale adoption short (seconds-hours) long (hours-days) duration storage. Currently, long-duration pumped hydro storage (PHES) accounts about 95% global the electricity sector. This paper discusses Global PHES Atlases developed by Australian National...

Decarbonization of the electricity system coupled with electrification transport, heat and industry represents a practical cost-effective approach to deep decarbonization. A key question is: where build new solar wind farms? This study presents cost-based evaluate land parcels for farm suitability using colour-coded heatmaps that visually depict favourable locations. An indicative cost is calculated each pixel by focusing on factors including resource availability, proximity transmission...

The decarbonization of the electricity system coupled with electrification transport, heat, and industry represents a practical cost-effective approach to deep decarbonization. A key question is as follows: where build new solar wind farms? This study presents cost-based evaluate land parcels for farm suitability using colour-coded heatmaps that visually depict favourable locations. An indicative cost calculated classified each pixel by focusing on factors including resource availability,...

<title>Abstract</title> Global commitments to net-zero emissions, and increasing electricity demand, require an unprecedented scale of new transmission infrastructure. Yet, most existing planning approaches rely on simplified models or incremental upgrades, overlooking the complex interplay renewable resource availability, grid balancing needs, challenges routing lines across vast terrains. In this paper, we introduce integrated expansion method that seamlessly unifies strategic system-wide...

Ureteral-arterial fistula (UAF) is an exceedingly rare but life-threatening condition warranting emergent intervention. Prompt recognition and management of UAF in suspect patients presenting with gross hematuria are required for a successful outcome. We report subset involving the bilateral common iliac arteries. The patient underwent endovascular stent-grafting to correct arterial defect delayed open repair ureteral strictures. Timely has benefited from collaboration involved medical...

K. R. Paap and L. S. Johansen (1994) proposed that word frequency effects do not occur on a lexical decision task (LDT) when postmasked target exposure duration is sufficiently brief because such prevents verification--their hypothesized locus of the effect. In making this assertion, they activation interpretation A. Dobbs, Friedman, J. Lloyd (1985) P. Allen, M. McNeal, D. Kvak (1992) was flawed. However, evidence Johansen's conclusions were wrong their experimental design contained flaws...

The authors conducted 2 studies to examine potential age-related differences in object-based attentional selection. Participants were briefly presented with pairs of wrenches and asked make 1 response if both target properties (i.e., an open end a hexagonal end) present another only single property was the display. critical manipulation whether on wrench or distributed between wrenches. Space-based models selective attention predict no difference performance these conditions. However,...
