An analytical expansion of the disturbing function arising from direct planetary perturbations on the motion of satellites is derived. As a Fourier series, it allows the investigation of the secular effects of these direct ...

The present study shows that nicotinamide prevents the long-term eVect of perinatal asphyxia on dopamine release monitored with in vivo microdialysis in the neostriatum of 3-month-old rats. Perinatal asphyxia was induced ...

In terms of stability around the primary, it is widely known that the semimajor axis of the retrograde satellites is much larger than the corresponding semimajor axis of the prograde satellites. Usually this conclusion is ...

The stability of the (87) Sylvia system and of the neighborhood of its two satellites is investigated. We use numerical integrations considering the non-sphericity of Sylvia, as well as the mutual perturbation of the ...

Glucocorticoids (GC) are the hormonal mediators of stress. In mammals, high levels of GC have negative eVects on reproductive physiology. For instance, GC can inhibit testicular testosterone synthesis by acting via ...

The triple asteroidal system (87) Sylvia is composed of a 280-km primary and two small moonlets named Romulus and Remus (Marchis et al. 2005b). Sylvia is located in the main asteroid belt, with semi-major axis of about ...

Tetragonisca angustula stingless bees are considered as solitary foragers that lack speciWc communication strategies. In their orientation towards a food source, these social bees use chemical cues left by co-speciWcs and ...

Neoseiulus baraki Athias-Henriot (Acari: Phytoseiidae) has been reported from the Americas, Africa and Asia, often in association with Aceria guerreronis Keifer (Acari: Eriophyidae), one of the most important pests of ...
