Laser‐driven hydrodynamic perturbation in an overdense Z‐pinch plasma
(The American Institute of Physics, 1979-04)
Holographic interferometry of the interaction of a radially incident intense CO2 laser beam (1011 W/cm2, 38‐nsec FWHM pulse) with an overdense helium Z‐pinch plasma (ne≳1019 e/cm3, Te∼20 eV, L=100 μm) has indicated the ...
Direct measurements bearing on the question of the nighttime heating mechanism in the ionosphere
(Elsevier, 1967-01)
Langmuir probe measurements of electron temperature and density were made in the upper F-region on two different occasions near local midnight. The experiments were carried out at Fort Churchill, Canada, and at Wallops ...
Does schooling reduce fast-start response latencies in teleosts?
(Elsevier, 1980)
1. 1. Response latencies, denned as the time between a d.c. electric shock and initiation of a fast-start (startle response) were measured for eight species of teleosts.2. 2. Fast-start response latencies varied from 10 ...
Differential operators commuting with invariant functions
(Birkhäuser Verlag; Birkhäuser Verlag, Basel, ; Springer Science+Business Media, 1997-10)
Let be a reductive, complex Lie algebra, with adjoint group G , let G act on the ring of differential operators via the adjoint action and write for the differential of this action. We prove that the commutant, in , of is ...
Social interactions between captive adult male and infant lowland gorillas: Implications regarding kin selection and zoo management
(John Wiley & Sons, Inc., 1999)
Interactions between unrelated and related silverback-infant dyads are compared in an attempt to assess the influence that kinship may have on male parental behavior. Observational data were collected on each member of two ...
Environmental influences on mountain gorilla time budgets
(Wiley Subscription Services, Inc., A Wiley Company, 1988)
Data on the time budgets of mountain gorillas ( Gorilla gorilla beringei ) were collected during field studies in the Virunga Volcanoes region of Rwanda and Zaire. Focal sampling was used to determine the proportion of ...
The direct enhancement of positive palatability by chlordiazepoxide is antagonized by Ro 15-1788 and CGS 8216
(Elsevier, 1987-04)
In a pre previous study, it was found that positive, palatability-dependent consummatory reactions in rats to intraorally infused tastes were facilitated by chlordiazepoxide (10 mg/kg). In contrast, the rats' more neutral ...
Dorsal cerebral collaterals of stroke-prone spontaneously hypertensive rats (SHRSP) and Wistar Kyoto rats (WKY)
(Wiley Subscription Services, Inc., A Wiley Company, 1987-05)
Earlier studies established that stroke-prone spontaneously hypertensive rats (SHRSP) invariably infarct after middle cerebral artery (MCA) occlusion. Normotensive rats are usually protected from infarction after the ...
Schlieren measurements of the hydrodynamics of excimer laser ablation of polymers in atmospheric pressure gas
(The American Institute of Physics, 1990-08-01)
Pulsed schlieren photography and fast helium‐neon laser deflection are used to study the hydrodynamics of laser ablation of polyethyleneterephthalate and polymethylmethacrylate by pulsed KrF (248 nm) radiation in atmospheric ...
The regeneration of brachial nerves of contralateral origin into denervated fused newt forelimbs Supported by NIH Training Grant 5 TO1 GM 00312-15 and a grant from the Muscular Dystrophy Association of America to Dr. Bruce M. Carlson. Reported earlier in abstract form (Goshgarian, '75a). This material is part of a thesis for the degree of Doctor of Philosophy, University of Michigan.
(Wiley Subscription Services, Inc., A Wiley Company, 1976-09)
Previous studies involving the end-to-end fusion of the forelimbs of the adult newt have demonstrated that new limbs can regenerate from the transected ends of proximo-distally reversed limb segments. The limb regeneration ...
