Comportement de mâles stériles de Glossina tachinoides West. lâchés dans les conditions natuelle - environs de Fort-Lamy (Tchad). II. Longévité et dispersion

Revue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 1973
Des lots de mâles d'élevage stérilisés par irradiation y et de mâles sauvages ont été lâchés dans un gîte bordant un bras mort du Chari. Les recaptures, effectuées à des délais réguliers, montrent que les facteurs «élevage, voyage» abaissent la longévité

On the assessment of the nature of open star clusters and the determination of their basic parameters with limited data [PDF]

, 2017
Our knowledge of stellar evolution and of the structure and chemical evolution of the Galactic disk largely builds on the study of open star clusters. Because of their crucial role in these relevant topics, large homogeneous catalogues of open cluster ...

Cerebral hemodynamic characteristics of acute mountain sickness upon acute high-altitude exposure at 3,700 m in young Chinese men. [PDF]

, 2014
PURPOSE: We aimed at identifying the cerebral hemodynamic characteristics of acute mountain sickness (AMS). METHODS: Transcranial Doppler (TCD) sonography examinations were performed between 18 and 24 h after arrival at 3,700 m via plane from 500 m (n ...

X-Ray sum frequency generation; direct imaging of ultrafast electron dynamics [PDF]

, 2018
X-ray diffraction from molecules in the ground state produces an image of their charge density, and time-resolved X-ray diffraction can thus monitor the motion of the nuclei.

Equivalents lait et rendements en produits laitiers : modes de calculs et utilisation

Revue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 1998
Pour des besoins statistiques, il peut être parfois utile de comparer des quantités de produits laitiers entre elles en les ramenant à des quantités équivalentes de lait. Pour cela, des coefficients de conversion sont utilisés.

Transcranial Doppler and magnetic resonance angiography assessment of intracranial stenosis: An analysis of screening modalities

Brain Circulation, 2020
BACKGROUND: Time-of-flight (TOF) magnetic resonance angiography (MRA) of the head and transcranial Doppler (TCD) are used to diagnose intracranial stenosis, an important cause of ischemic stroke. We aimed to compare TCD findings with TOF-MRA results in a

Photocatalytic Versus Stoichiometric Hydrogen Generation Using Mesoporous Silicon Catalysts: The Complex Role of Sacrificial Reagents

Advanced Functional Materials, EarlyView.
This study highlights the importance of accounting for stoichiometric hydrogen produced when utilizing Si photocatalysts. The stoichiometric contribution is sacrificial reagent dependent and decreases with increasing sterics around the catalyst surface.

A simplicial $A_\infty$-operad acting on $R$-resolutions [PDF]

, 2009
We construct a combinatorial model of an A-infinity-operad which acts simplicially on the cobar resolution (not just its total space) of a simplicial set with respect to a ring R.Comment: 18 pages; part 2 of a paper formerly called "$A_\infty$-monads ...
