In 1940, with the fall of France imminent, Britain prepared for invasion. After Dunkirk, with most armour and transport lost, a defence ‘stop line’ (GHQ Line) was prepared. Local Defence Volunteers (later Home Guard) were raised to buy time for the Home Army to deploy. Secret ‘Auxiliary Units’ were also formed, tasked with ‘Scallywagging’ – guerrilla activities ––in the invading army’s rear. 4-8 [...]

Single-blind test of airplane-based hyperspectral methane detection via controlled releases

Evan David Sherwin, Yuanlei Chen, Arvind P Ravikumar, et al.

Published: 2020-01-08
Subjects: Education, Engineering, Other Engineering

Methane leakage from point sources in the oil and gas industry is a major contributor to global greenhouse gas emissions. The vast majority of such emissions come from a small fraction of "super-emitting" sources which, once detected, can generally be fixed at relatively low cost. We evaluate the emission detection and quantification capabilities of Kairos Aerospace’s airplane-based hyperspectral [...]

Learning by Doing: Enhancing Hydrology Lectures with Individual Fieldwork Projects

Anne Van Loon

Subjects: Education, Higher Education, Scholarship of Teaching and Learning

Hydrology teaching deals with processes happening outside the classroom, which calls for active-learning methods to complement lectures. In a geography undergraduate course, new teaching methods and assessment were designed, in which students investigated a river of their choice by completing homework tasks and presenting their results on a poster. During a 3-year implementation process, the [...]

Unfolding Veined Fold Limbs to Deduce a Basins Prefolding Stress State

Koen Van Noten, Manuel Sintubin

Published: 2019-03-06
Subjects: Earth Sciences, Education, Outdoor Education, Physical Sciences and Mathematics, Tectonics and Structure

Tectonic structures that developed prior to folding, such as pre- and early-kinematic veins, hold valuable information on the stress state of the paleobasin in which these early structures formed. To derive the parental orientation of these prefolding brittle structures, folds need to “unfold.” A fold restoration methodology is presented in which fold limbs, and the structures they contain, are [...]
