Preparing for Juice’s daring double flyby

En

Next month, ESA’s Jupiter Icy Moons Explorer (Juice) will carry out the first combined lunar-Earth flyby. Preparations are under way at ESA mission control for this highly precise manoeuvre, which will harness the gravitational forces of the Moon and Earth in quick succession to line Juice up for the next stage of its journey to Jupiter.

Can the U.S. Avoid an Energy Crisis?

Oilprice.com 
En

Authored by Danny Ervin via RealClearEnergy, I am generally pessimistic about the future of the U.S. due to recent energy policies at the federal and state levels that favor "green" energy technologies, primarily solar and wind. These policies often distort the economics of power production, leading to a massive misallocation of capital and overinvestment in unreliable solar and wind projects. Reliable electricity supply requires consistency every second of the day, not just minute-by-minute, but also over weeks, months, and years. Читать дальше...

The impact of digital transformation of infrastructure on carbon emissions: Based on a "local-neighborhood" perspective

by Jinzhao Song, Qiyue Gao, Xiangxiang Hu, Jie Lei

In light of the recent worldwide scientific and technological revolution, it is imperative that urban infrastructure undergo a digital transformation in order to lower carbon emissions and support sustainable urban growth. However, to date, there is a lack of empirical research on carbon emissions based on the digital transformation of urban infrastructure. This paper uses data from 178 prefecture-level cities in China from 2005 to 2020 to... Читать дальше...

Study on deformation of tunnel pile foundation based on discrete element method and finite difference method

by Zhenchu Zhao, Yuan Zhang, Fang Dai

The deformation of pile caused by tunnel excavation will weaken the bearing capacity of the foundation. In order to investigate the deformation response of pile induced by the construction of three-hole small spacing tunnel, the DEM-FDM (discrete element method and finite difference method) coupling numerical simulation method were used to simulate the deformation process of pile during tunnel excavation. This paper probed into the deformation response of pile by three factors... Читать дальше...

Health system adaptations for extreme heat: Protocol for an international scoping review of reviews

En

by John Richmond, Mark Clowes

Objective

The objective of this study is to map the international evidence for extreme heat related adaptation strategies by health systems, with a particular focus on how heat-vulnerable populations and local situational awareness are considered in these strategies.

Introduction

Since the Paris Climate Accords in 2015, awareness has increased of the health risks posed by extreme heat along with interest in adaptations which aim to reduce heat-health-risks for vulnerable populations. Читать дальше...
