Who Cares: Why the Israeli–Palestinian Conflict Matters (More) to Some EU Member States

JCMS: Journal of Common Market Studies, EarlyView.
Abstract What drives the salience of the Israeli–Palestinian conflict amongst EU member states? This article employs domestic foreign policy theories to explain the factors underlying variation in salience, estimated analysing all country statements made at the United Nations General Assembly between 1993 and 2017.

Method of gas flows calculation in solid propellant rocket engines taking into account the combustion of solid fuel charge

IOP Conference Series: Materials Science and Engineering, 2019
The paper presents a method for calculating the local and integral characteristics of the flow in the axisymmetric gas-dynamic paths of solid propellant rocket motors, taking into account the combustion of a charge of solid fuel.

The Monetary Policy–Commodities Nexus: A Survey

Journal of Economic Surveys, EarlyView.
ABSTRACT This survey synthesizes evidence on the bidirectional links between commodity markets and monetary policy. On the commodities‐to‐policy side, we review how shocks to energy, food, and metals pass through to inflation, inflation expectations, economic activity, and financial stability in state‐dependent ways that vary by shock type, exposure ...

Small but mighty: Impact hazards from iron Near‐Earth Objects

Meteoritics &Planetary Science, EarlyView.
Abstract Small asteroids can impact Earth unexpectedly, as demonstrated by the Chelyabinsk event in 2013. The warning times are likely to be short, and the first tools for fast hazard predictions have been developed in the last years for encounters with rocky or cometary objects, which quickly fragment in the atmosphere and cause airbursts. However, in

Validation of Integral Method for Numerical Prediction of Hybrid Rocket Internal Ballistics

Journal of Fluid Science and Technology, 2013
In order to design hybrid rocket engines, we developed a numerical prediction method which describes the internal ballistics, thus the solid fuel regression rate. In order to obtain a fast code, simple but efficient models have been implemented.

The Downward Spiral of Legitimacy Erosion: Lessons on Network Governance Failure During the German “Refugee Crisis”

Public Administration Review, EarlyView.
ABSTRACT Organizational legitimacy is essential for effective crisis governance. This study analyzes the rapid erosion of legitimacy faced by the German State Office for Health and Social Affairs (LAGeSo) during the 2015 refugee crisis, triggering cascading failures in public service delivery.

Noisy Politics, Quiet Technocrats: Strategic Silence by Central Banks

Regulation &Governance, EarlyView.
ABSTRACT In contrast to the “quiet” politics of the pre‐2008 period, macroeconomic policy has become “noisy”. This break raises a question: How do independent agencies designed for quiet politics react when a contentious public turns the volume up on them?

Comparative effects of a glucose–fructose bar, glucose–fructose hydrogel and maltodextrin gel on carbohydrate oxidation and sprint performance in Tier 2 athletes

Experimental Physiology, EarlyView.
Abstract Carbohydrate supplementation optimises athletic performance, but the metabolic and performance impacts of commercial products/compositions are underexplored. We compared the efficacy of three commercial carbohydrate supplements: a glucose–fructose bar (GF‐Bar), a glucose–fructose hydrogel (GF‐Gel) and a maltodextrin‐based gel (MD‐Gel ...

Analysis of carbon nano particle variant as the propellant fuel to increase specific impulses of rockets [version 3; peer review: 1 approved, 2 approved with reservations]

F1000Research
Background This study compares propellant fuels’ specific thrust and impulse parameters using nanocarbon variant fuels from coconut shells and coal. Specific impulses and impulses are essential parameters that determine rocket performance.
