Expression profiling of glial genes during Drosophila embryogenesis

2006

AbstractIn the central nervous system of Drosophila, the induction of the glial cell fate is dependent on the transcription factor glial cells missing (gcm). Though a considerable number of other genes have been shown to be expressed in all or in subsets of glial cells, the course of glial cell differentiation and subtype specification is only poorly understood. This prompted us to design a whole genome microarray approach comparing gcm gain-of-function and, for the first time, gcm loss-of-function genetics to wildtype in time course experiments along embryogenesis. The microarray data were analyzed with special emphasis on the temporal profile of differential regulation. A comparison of bo…

Variations in the volatile compounds of a Fennel (Foeniculum vulgare Mill.) variety grown in a semi-arid Mediterranean environment

2005

Fennel is an industrial source of anethole but, recently, further interest has came from the suggested possibility of many industrial uses of this plant. The volatile substances from the seeds of fennel grown in Sparacia (Cammarata - AG - Sicily; 37° 38' N; 13° 46' E) have been investigated and compared on a statistical base with previously reported data. The variety grown in Sparacia fall into the "high fenchone" chemovariety. The substances alpha-toluene, alpha-terpinene, beta-phellandrene + limonene and camphene appear the components most sensitive to environment and grow condition modifications. Fennel is an industrial source of anethole but, recently, further interest has come from the…

Le intese restrittive della concorrenza nell'attività dell'Agcm (anno 2015)

2016

La prassi dellAutorità garante della concorrenza e del mercato (qui di seguito « Agcm »), nel corso del 2015, non mostra significativi scostamenti rispetto agli orientamenti consolidati nellambito dellapplicazione della disciplina antitrust alle intese restrittive della concorrenza. È interessante notare, comunque, che gran parte delle condotte oggetto di analisi ha riguardato ipotesi di collusione tra i partecipanti a gare ad evidenza pubblica, integrando in prevalenza fattispecie di intese continuate e complesse aventi ad oggetto la compartimentazione dei relativi mercati. Significativo, inoltre, è il fatto che a partire dal 2015 l'Agcm ha iniziato ad applicare le Linee Guida nazionali in…

Decisioni con impegni, programmi di clemenza e misure cautelari nell'attività dell'Agcm (anno 2013)

2014

L'analisi delle decisioni dell'Autorità garante della concorrenza e del mercato (Agcm) nel corso del 2013 dimostra un utilizzo limitato degli strumenti ad essa conferiti in attuazione del cd. decreto Bersani (d.l. 4 luglio 2006, n. 223). Con riferimento alle decisioni con impegni, si nota che, a differenza di quanto avvenuto negli anni immediatamente successivi alla loro introduzione nell'ordinamento giuridico italiano, la prassi più recente dell'Agcm è caratterizzata da un utilizzo residuale di tale istituto. Dunque, in tale nuova prospettiva, i provvedimenti di accettazione di impegni rappresentano, coerentemente con la loro funzione, strumenti eccezionali, di applicazione limitata, non i…

Changing European storm loss potentials under modified climate conditions according to ensemble simulations of the ECHAM5/MPI-OM1 GCM

2007

Abstract. A simple storm loss model is applied to an ensemble of ECHAM5/MPI-OM1 GCM simulations in order to estimate changes of insured loss potentials over Europe in the 21st century. Losses are computed based on the daily maximum wind speed for each grid point. The calibration of the loss model is performed using wind data from the ERA40-Reanalysis and German loss data. The obtained annual losses for the present climate conditions (20C, three realisations) reproduce the statistical features of the historical insurance loss data for Germany. The climate change experiments correspond to the SRES-Scenarios A1B and A2, and for each of them three realisations are considered. On average, insure…

Rainfall variability in subequatorial America and Africa and relationships with the main sea-surface temperature modes (1951–1990)

1995

The rainfall variability of subequatorial South America and Africa is poorly documented owing to the scarcity of data. We present a new land-only data set of monthly precipitation from 1951 to 1990, focusing on subequatorial South America and Africa, which improves the knowledge of rainfall variability and allows comparisons with GCM outputs. The results of multivariate analyses are compared with those performed on the best actual global rainfall data set developed by Mike Hulme. The main modes of bimonthly rainfall variability are not located in the major rain-forest basins of Za'ke and Amazonia, but rather on the tropical margins, such as Venezuela or Sudan, and near-coastal equatorial ar…

Changes in the frequency of the Weather Regimes over the Euro-Atlantic and Mediterranean sector and their relation to the anomalous temperatures over…

2013

19 pages; International audience; An exercise has been carried out to assess to what extent the Euro-Atlantic Weather Regimes (WR),described from the ERA-interim Reanalysis in the summer season, projects onto a pool of AGCMAMIPsimulations in which sea surface temperatures (SST) are prescribed from observations.Although the model simulations present some biases in the spatial structure and seasonality of WRs,exhibiting also less variability, they are able to capture main WR over the region in summer season:+Middle East –Middle East, +NAO, -NAO. WR paradigm is used to quantify changes in theatmosphere under warmer/colder than normal conditions over the Mediterranean Sea. To addressthis proble…

The West African Monsoon Modeling and Evaluation project (WAMME) and its First Model Intercomparison Experiment

2008

International audience; This paper presents the scientific challenge in West African monsoon (WAM) simulation and discusses the West African Monsoon Modeling and Evaluation project (WAMME) initiative and its approaches to improve WAM simulations. Major scientific highlights from the first WAMME model comparison are the focus of the paper. Based on the first WAMME experiment, the WAMME models' performance is evaluated with precipitation being the major focus. The analyses indicate that the models with specified SST generally have reasonable simulations of the mean spatial distribution of WAM precipitation but largely fail to produce proper daily precipitation frequency distributions. WAMME m…
