Despite recent striking advances in assisted reproductive technology (ART), poor ovarian response (POR) diagnosis and treatment is still considered challenging.Poor responders constitute a heterogeneous cohort with the common denominator of under-responding to controlled ovarian stimulation.Inevitably, respective success rates Pillow are significan
We give a necessary and sufficient condition for the existence of a positive principal eigenvalue for a periodic-parabolic problem with indefinite weight function.The condition was originally established by Beltramo and Hess [extit{frenchspacing Comm.Part.Diff.Eq.}, extbf{9} (1984), Serving Tongs 919--941] in the framework of the Schauder theory of
The 24th Japanese Antarctic Research Expedition (JARE-24) took charge of the second year survey of the three-year programme for Antarctic marine biological investigations near Syowa Station.The second year programme was planned to lay stree on primary producers in water column and in sea ice.Investigations on seasonal variations of standing stock,
Anatomical Kit Purificante variations can be seen in any part of the body and unless they are identified through imaging, during surgery, or on autopsy most of them will never be detected.Anatomical variations of the sciatic nerve in relation to the piriformis have been described for many years and so has possible implications these variations migh
The chasing behaviour of male blowflies after small targets belongs to the most rapid and virtuosic visually guided behaviours found in nature.Since in a structured environment any turn towards a target inevitably leads to a displacement of the entire retinal image in the opposite direction, it might evoke optomotor following responses counteractin
