4Artificial equilibrium points and bi-impulsive maneuvers to observe 243 Ida显示文摘In the restricted three-body problem,the traditional Lagrange points L1 and L2 are the only equilibrium points near the asteroid 243 Ida.The thrust generated by a solar sail over a spacecraft enables the existence of new artificial equilibrium points,which depend on the position of the spacecraft with respect to the asteroid and the attitude of the solar sail.Such equilibrium points generate new spots to observe the body from above or below the plane of motion.Such points are very good observational locations due to their stationary condition.This work provides a preliminary analysis to observe Ida through the use of artificial equilibrium points as spots combined with transfer maneuvers between them.Such combination can be used to observe the asteroid from more different points of view in comparison to fixed ones.The analyses are made for a spacecraft equipped with a solar sail and capable of performing bi-impulsive maneuvers.The solar radiation pressure is used both to maintain the equilibrium condition and to reduce the costs of the transfers and/or to create transfers with longer duration.This is a new aspect of the present research,because it combines the continuous thrust with initial and final small impulses,which are feasible for most of the spacecraft,because the magnitudes of the impulses are very low.These combined maneuvers may reduce the transfer times of the maneuvers in most of the cases,compared with the maneuvers based only on continuous thrust.Several options involved in these transfers are shown,like to minimize the fuel spent(Dv)as a function of the transfer time or to extend the duration of the travel between the points.Extended transfer times can be useful when observations are required during the transfers.Allan Kardec de ALMEIDA Jr Geraldo Magela Couto OLIVEIRA Antonio Fernando Bertachini de Almeida PRADO 2021Chinese Journal of Aeronautics2021,34,1:1

9Olea europaea leaves delay the onset of toxicity of Cerastes cerastes venom in male Swiss albino mice显示文摘We investigated the anti-Cerastes cerastes venom effect of aqueous olive leaf extract.The mitigation in the mean survival time of the albino mice were used to deduce the antivenom property of this extract after challenging with LD99 of snake venom.The aqueous extract of olive leaf significantly increases the mean survival time and the protection fold,but could not protect animals from death when used alone.The higher dose,i.e.,33 g/kg was found better than that of the lower dose of 15 g/kg.The anti-snake venom was found to be more efficient than the aqueous olive leaf extract.Inass A Al sadawia Alla M.
