Abstract:
Saturn’s rings are an accessible exemplar of an astrophysical disk, tracing the Saturn system’s dynamical processes and history. We present close-range remote-sensing observations of the main rings from the Cassini spacecraft. We find detailed sculpting of the rings by embedded masses, and banded texture belts throughout the rings. Saturn-orbiting streams of material impact the F ring. There are fine-scaled correlations among optical depth, spectral properties, and temperature in the B ring, but anticorrelations within strong density waves in the A ring. There is no spectral distinction betwee

The status of constructions of the type non-prefixed verb + adverb with regard to expressing aspectuality (iet iekšā ‘to go in’, vērt vaļā ‘to open up’ etc.) is one of the most interesting problems in Latvian aspectology. However, too little attention has been paid in Latvian linguistics to the use of such constructions in sentences, as well as to the lexical (spatial) meanings of adverbs and their syntactic functions. This study aims to fill that gap, taking a closer look at the ways in which constructions of the type non-prefixed verb + adverb are used in sentences, as well as at the semanti

This thesis examines the origin and relative timing of carbonate alteration zones in the poly-deformed Doolena Gap Greenstone Belt in the East Pilbara Terrane, the type locality of Archaean dome-and-keel-terranes. The key findings are: [1] shear-assisted carbonate alteration occurred throughout the entire tectonic history of the greenstone belt; and [2] weak pre- and syntectonic carbonate minerals make up 40 to 60% of the examined greenstone rocks. These outcomes imply that carbonate minerals likely controlled the strength of Archaean lithosphere.

Abstract:
Abstract The Upstream oil and gas industry is adopting more and more environmentally friendly solutions to achieve the COP 21 goal set in Paris in 2015 (i.e., no more than 1.5°C of global temperature rise versus the pre-industrial levels). As such, when selecting a technology on a project, operators started acknowledging the need to adopt not only economic solutions but also low carbon ones. Some technologies today can already give an answer to the decarbonization challenge. In Offshore deep waters, which is an area keener to innovate and where many future field developments would happen, rota

While some livestock production in some places contributes significantly to climate change, this is not universally the case. This article focuses on pastoral production systems – extensive, often mobile systems using marginal rangelands across around half of the world’s surface, involving many millions of people. By examining the assumptions behind standard calculations of greenhouse gas emissions, a systematic bias against pastoralism is revealed. Many policy and campaign stances fail to discrimina
