Battery sizing for a stand alone passive wind system using statistical techniques [PDF]

open access: yes, 2011
In this paper, an original optimization method to jointly determine a reduced study term and an optimum battery sizing is investigated. This storage device is used to connect a passive wind turbine system with a stand alone network. A Weibull probability

Model simplification and optimization of a passive wind turbine generator [PDF]

open access: yes, 2009
In this paper, the design of a "low cost full passive structure" of wind turbine system without active electronic part (power and control) is investigated. The efficiency of such device can be obtained only if the design parameters are mutually adapted

The Impact of Maturation Medium Supplemented with PMSG and HCG Hormones on In vitro Maturation of Ovine Oocytes [PDF]

open access: yesJournal of Applied Veterinary Sciences
This investigation aimed to assess the dose-dependent impact of the pregnant mare serum gonadotropin (PMSG) on the in vitro maturation of sheep oocytes and the effect of combining the best dose with the human chorionic gonadotropin (hCG), which is a cost-

Different estrous induction methods during the non-breeding season in Kivircik ewes

open access: yesVeterinární Medicína, 2006
The efficiency of medroxyprogesterone acetate (MAP) sponges in combination with either pregnant mare serum gonadotrophin (PMSG) or cloprostenol (PGF2α) for inducing and synchronizing the estrous cycle in non-lactating Kivircik ewes was investigated ...
