Thermal induction of diploid gynogenesis
Sporadic diploid gynogenetic fry resulted from fertilization with y-irradiated sperm. Their frequency increased appreciably when thermal shock treatments, beginning during the first hour of development (―0.4 OC lasting 6 hrs 45 min ; 26-30 °C lasting 10 min), were used. When the eggs were fertilized with normal sperm, a good triploidization rate was induced by means of heat shocks (27-30...
متن کاملThe experimental induction of gynogenesis in the mouse I. Irradiation of the sperm by X-rays
Sperm of the mouse, M us musculus, was X-irradiated in vitro before fertilization. Dosages were between 100 and 50 000 r. With increasing irradiation of the sperm, the chromosome complement of embryos, scored at 3ijr days’ gestation, declined from diploid to haploid. Higher dosages increasingly retarded embryonic development, 30000 and 50 000r restricting development to the first cleavage. Gyno...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولAttempted induction of chronic copper poisoning in boma confined impala.
Induction of chronic copper poisoning in ten boma-confined impala was attempted in a randomized, single dose, parallel designed, titration study using five increasing oral doses, ranging between 125 mg/kg to 1000 mg/kg, of copper oxide needles. Two untreated impala were kept as controls. Impala (n = 1) from each treatment group were culled 52 d and 105 d after treatment and examined for tissue ...
