Diagnosis and prevalence of uterine leiomyomata in female chimpanzees ( Pan troglodytes )
(Wiley Subscription Services, Inc., A Wiley Company, 2011-07)
Uterine leiomyomata are common, affecting 70–80% of women between 30 and 50 years of age. Leiomyomata have been reported for a variety of primate species, although prevalence rates and treatments have not been widely ...
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 ...
Influence of Mn dopants on InAs/GaAs quantum dot electronic states

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 ...
Proteomic screening and identification of differentially distributed membrane proteins in Escherichia coli
(Blackwell Science Ltd, 2004-05)
Bacteria show asymmetric subcellular distribution of many proteins involved in diverse cellular processes such as chemotaxis, motility, actin polymerization, chromosome partitioning and cell division. In many cases, the ...
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 ...
Hydrodynamics and microphase ordering in block copolymers: Are hydrodynamics required for ordered phases with periodicity in more than one dimension?
(The American Institute of Physics, 2004-12-08)
We use Brownian dynamics (BD), molecular dynamics, and dissipative particle dynamics to study the phase behavior of diblock copolymer melts and to determine if hydrodynamics is required in the formation of phases with ...
