A mathematical tool for describing the behaviour of a dense effluent discharge

2009

In many cases a dense effluent has to be discharged in the environment with possible harmful consequences. The preferred design for the relevant discharge unit is that of a simple or multi-port diffuser issuing jets at a given inclination above the horizontal. This work presents the follow-on developments of a model previously proposed to predict the behaviour of inclined dense jets issuing in a stagnant environment. It consists of a set of three ordinary differential equations that can be solved by standard numerical methods. Model outputs include information on the trajectory, spreading and dilution of inclined dense jets, return point position and concentration. Interestingly the model a…

User-oriented evaluation of mechanical single-channel axial pipettes.

2013

Hand tools should be designed so that they are comfortable to use, fit the hand and are user-oriented. Six different manual, single-channel axial pipettes were evaluated for such objective outcomes as muscular activity, wrist postures and efficiency, as well as for subjective outcomes concerning self-assessed features of pipette usability and musculoskeletal strain. Ten experienced laboratory employees volunteered for the study. The results showed that light and short pipettes with better tool comfort resulted in reduced muscular activity and perceived musculoskeletal strain when they were compared with a long and heavy pipette. There were no differences in the efficiency between the differ…

GW170814: A Three-Detector Observation of Gravitational Waves from a Binary Black Hole Coalescence

2017

On August 14, 2017 at 10 30:43 UTC, the Advanced Virgo detector and the two Advanced LIGO detectors coherently observed a transient gravitational-wave signal produced by the coalescence of two stellar mass black holes, with a false-alarm rate of 1 in 27 000 years. The signal was observed with a three-detector network matched-filter signal-to-noise ratio of 18. The inferred masses of the initial black holes are 30.5-3.0+5.7M and 25.3-4.2+2.8M (at the 90% credible level). The luminosity distance of the source is 540-210+130 Mpc, corresponding to a redshift of z=0.11-0.04+0.03. A network of three detectors improves the sky localization of the source, reducing the area of the 90% credible regio…

Molecular tools to monitor a biocontrol agent and to assess its environmental impacts

2008

The use of non pathogenic strains of Fusarium oxysporum has been proposed to control Fusarium diseases responsible for severe damages in many crops of economical importance. In order to monitor the biocontrol strain Fo47 after application in greenhouse and field, we have developed a specific molecular tool based on a sequence characterized amplified region (SCAR). Primers targeting a 210-bp fragment were designed to set up a real time PCR assay allowing the identification of the biocontrol strain and its quantification in environmental samples. The assay enabled specific detection of the strain in soils without cross detection of autochthonous populations of F. oxysporum. After its introduc…

Novel bibliographic maps to guide research units

2014

National audience; Publication is a major issue for research evaluation. As a consequence research units need strategies to improve their publications. Bibliometry and cartography are new tools to study the publications of research teams. In particular bibliometry give an overall picture and good criteria to choose a strategy for publishing and to guide the priorities of research. Here we studied the publications of the INRA Agroécologie research unit, Dijon. This unit has 107 scientists and professors, equivalent 80 full-time positions for research, and published 125 original articles in 2012. We present several examples of maps and measurements obtained using Web of science, Excel, Sphinx…

Identification and diagnosis of patients with familial chylomicronaemia syndrome (FCS): Expert panel recommendations and proposal of an "FCS score".

2018

Familial chylomicronaemia syndrome (FCS) is a rare, inherited disorder characterised by impaired clearance of triglyceride (TG)-rich lipoproteins from plasma, leading to severe hypertriglyceridaemia (HTG) and a markedly increased risk of acute pancreatitis. It is due to the lack of lipoprotein lipase (LPL) function, resulting from recessive loss of function mutations in the genes coding LPL or its modulators. A large overlap in the phenotype between FCS and multifactorial chylomicronaemia syndrome (MCS) contributes to the inconsistency in how patients are diagnosed and managed worldwide, whereas the incidence of acute hypertriglyceridaemic pancreatitis is more frequent in FCS. A panel of Eu…

KunstHandWerk - Beiträge der 26. Tagung der AG Eisenzeit gemeinsam mit der Keltenwelt am Glauberg und der hessenARCHÄOLOGIE im Landesamt für Denkmalp…

2018

International audience; Die 26. Sitzung der AG Eisenzeit fand vom 02. bis 06. Oktober 2013 im kleinen Kurort Nidda - Bad Salzhausen (Wetteraukreis/Hessen) statt. Zwei Jahre vorher war die „Keltenwelt am Glauberg - Museum, Archäologischer Park, Forschungszen- trum“ , ein Projekt der hessenARCHÄOLOGIE und des hessischen Ministeriums für Wissenschaft und Kunst, im 12 km südlich entfernten Glauburg eröffnet worden.Die Strahlkraft insbesondere der dort präsentierten einzigartigen Grabfunde aus drei keltischen Kriegergräbern am Fuße des Glaubergs inspirierte uns zu dem Tagungsthema "KunstHandWerk". Das Thema wurde in insgesamt 22 Vorträgen aufgegriffen, weitere zwei Vortragende stellten aktuelle …

Showing the Invisible: The Economic Cycle of Stone Tools

2023

This contribution takes place in a broader theme, that of “the invisible economy of recyclable materials”. It aims to illustrate the phenomena of recovery of materials from lithic tools and their consequences. The classification of tools by material, although classic, is not relevant from a technical point of view. The material of a tool, in particular its mechanical properties, is to be taken into consideration in its technical analysis, but it cannot constitute a determining criterion in a classification system. Function should come first, as most functional categories use multiple materials. The most striking example, if one can say so, is that of the striking supports, where one finds, …
