Dynamics of abelian subgroups of GL(n, C): a structure's Theorem

In this paper, we characterize the dynamic of every abelian subgroups $\mathcal{G}$ of GL($n$, $\mathbb{K}$), $\mathbb{K} = \mathbb{R}$ or $\mathbb{C}$. We show that there exists a $\mathcal{G}$-invariant, dense open set $U$ in $\mathbb{K}^{n}$ saturated by minimal orbits with $\mathbb{K}^{n}- U$ a union of at most $n$ $\mathcal{G}$-invariant vectorial subspaces of $\mathbb{K}^{n}$ of dimension $n-1$ or $n-2$ on $\mathbb{K}$. As a consequence, $\mathcal{G}$ has height at most $n$ and in particular it admits a minimal set in $\mathbb{K}^{n}-\{0\}$.Comment: 16 page

Influence of manufacturing parameters of knitted compression fabric on interface pressure

The influence of various parameters, such as knitted structure, elastane percentage, elastane yarn count and stitch length,on the interface pressure generated by compression knitted garment has been studied. An experimental device has beendeveloped to measure interface pressure by using a FlexiForce® sensor. The obtained result shows that the pressuregenerated by compression garment depends on the considered parameters. It is observed that plain knitted fabric causes highpressures on leg, generating a high value of interface pressure. Moreover, the increase in elastane percentage and elastaneyarn count cause an increase in interface pressure. Contrariwise, the increase in stitch length generates a decrease ininterface pressure. Mathematical models based on ANOVA analysis are also developed. The validity of these models hasbeen demonstrated using χ2-test

Meeting of the Ecosystem Approach Correspondence Group on on Pollution Monitoring (CorMon Pollution)

In accordance with the UNEP/MAP Programme of Work adopted by COP 21 for the biennium 2020-2021, the United Nations Environment Programme/Mediterranean Action Plan-Barcelona Convention Secretariat (UNEP/MAP) and its Programme for the Assessment and Control of Marine Pollution in the Mediterranean (MED POL) organized the Meeting of the Ecosystem Approach Correspondence Group on Pollution Monitoring (CorMon on Pollution Monitoring). The Meeting was held via videoconference on 26-27 April 2021. 2. The main objectives of the Meeting were to: a) Review the Monitoring Guidelines/Protocols for IMAP Common Indicator 18, as well as the Monitoring Guidelines/Protocols for Analytical Quality Assurance and Reporting of Monitoring Data for IMAP Common Indicators 13, 14, 17, 18 and 20; b) Take stock of the state of play of inter-laboratory testing and good laboratory practice related to IMAP Ecological Objectives 5 and 9; c) Analyze the proposal for the integration and aggregation rules for IMAP Ecological Objectives 5, 9 and 10 and assessment criteria for contaminants and nutrients; d) Recommend the ways and means to strengthen implementation of IMAP Pollution Cluster towards preparation of the 2023 MED Quality Status Report

Numerical simulation of compressible turbulent flow using algebraic Reynolds stress model

The explicit incompressible algebraic Reynolds stress model proposed by Gatski and Speziale [J. Fluid Mech. 254, 59 (1993)] has been extended to be applied to compressible turbulent flows. This extension is based on the modeled compressible transport equations for the Favre-averaged Reynolds stress tensor. The resulting model is tested in a variety of compressible turbulent flows which include the homogeneous shear flow and the compressible mixing layer. Comparisons between the present model predictions and the results of direct numerical simulations and experiments are quite encouraging
