The presence of valley networks and open-basin lakes in the late Noachian is cited as evidence for overland flow of liquid water and thus a climate on early Mars that might have supported precipitation and runoff. Outstanding questions center on the nature of such a climate, its duration and variability, and its cause. Open basin lakes, their interior morphology, and their associated channels p...

The plankton fauna of the state of Piauí, Northeastern Brazil, especially in the Parnaíba basin, is still poorly known; the results of most studies of the subject have not been published and can only be found in grey literature (unpublished scientific works), such as course completion work and consulting reports. Thus, this paper presents data from samples taken recently from different water bo...

Mineral assemblage and deformation conditions of metasediments metabasites the Tutak Complex, southeast Bavanat, Fars province

[1] The floor of Isidis Basin is covered by materials of the Vastitas Borealis Formation (VBF) that appear to be emplaced essentially as a single unit. Along its western boundary, Isidis Basin is in contact with volcanic flows from Syrtis Major Planum. The contact between the Isidis unit and volcanic flows from Syrtis Major is sharp to gradational and in places is characterized by a high ( 500 ...

Throughout the world, road traffic accidents (RTAs) and their consequences are studied to help develop new prevention and enforcement policies. Impaired driving among drunk or intoxicated drivers is a social and public health problem recognised worldwide and the presence of alcohol and drugs in drivers has been found to be frequent and the cause of fatal outcomes. According to US National Highw...

The research question addressed in this paper is whether or not occupant death, injury, and ejection outcomes differ between vehicles equipped with 3-point manual belts versus 2-point motorized-shoulder/manual-lap (motorized/manual) belt systems. Census crash data sets for the states of Washington and Texas, and the Fatal Accident Reporting System (FARS) were subset to provide data on front-out...

In recent decades, the Canada Basin of the Arctic Ocean has experienced rapidly decreasing summer sea ice coverage and freshening of surface waters. It is unclear how these changes translate to deeper waters, particularly as our baseline understanding of organic carbon cycling in the deep basin is quite limited. In this study, we describe full-depth profiles of the abundance, distribution and c...

primary objectives of this research included 1) develop models relating occurrence of two threatened inland salmonid fishes to stream temperature regimes; 2) develop a comprehensive protocol for sampling stream temperatures using digital data loggers. The two species of interest were bull trout (Salvelinus confluentus) and Lahontan cutthroat trout (Oncorhynchus clarki henshawi). The distributio...

—A warming climate could profoundly affect the distribution and abundance of many fishes. Bull trout Salvelinus confluentus may be especially vulnerable to climate change given that spawning and early rearing are constrained by cold water temperatures creating a patchwork of natal headwater habitats across river networks. Because the size and connectivity of patches also appear to influence the...

Spectral analyses of complementary lithologic and paleoecologic data sets from the Cenomanian-Turonian Bridge Creek Limestone are used to test for Milankovitch periodicities. Because the analyses quantitatively assess variance in the data sets through the study interval, they also offer a new method for evaluating relationships between different components of the depositional system. The analys...
