1.1 We prove that: Over any field I of characteristic p > 0, there exists an infinite dimensional Lie algebra which is the join of two (p + l)-dimensional and nilpotent (of class exactly p) subideals. A result of Hartley ([2; p. 259, theorems 2 and 5]) states that over any field of characteristic zero, the join of a pair of finite dimensional (resp. finite dimensional and nilpotent) subideals i...

The papers in this volume of Frontiers all relate to 3D vision. What, then, is a paper about visual stability doing among them? I will argue that these topics are really two sides of the same coin: if we are not to be surprised by the changes in images that occur as we move (we see a stable world), we must have some sort of representation of the 3D environment that has given rise to those image...

A sensory evaluation study was performed at UC Davis to determine if taste differences could be detected among several English walnut (Juglans regia) cultivars. Differences were tested using the duo-trio method, in which 'Hartley' was compared to seven other cultivars. No differences were found when 'Hartley' was compared to 'Vina', 'Scharsch Franquette' and 'Mayette', however 'Chandler', 'Chic...

Use of the hyperinsulinemic euglycemic clamp to assess insulin sensitivity in guinea pigs: dose response, partitioned glucose metabolism, and species comparisons.

Infection of the amniotic cavity remains a major cause of preterm birth, stillbirth, fetal injury and early onset, fulminant infections in newborns. Currently, there are no effective therapies to prevent in utero infection and consequent co-morbidities. This is in part due to the lack of feasible and appropriate animal models to understand mechanisms that lead to in utero infections. Use of mou...

are potent carcinogens in several species of animals (33) but have induced no tumors in the guinea pig (1, 8, 22, 30). That this contrasting response might be reflected in the metabolism of these compounds has been the object of several studies. Meade and Ray (21) found more combined diazotizable and less free diazotizable material after an intraperitoneal injection of 2-fluorenamine than was o...

Physical and immunological characteristics of the chimpanzee and guinea-pig subcutaneous chamber models for Neisseria gonorrhoeae infection were compared to evaluate their usefulness for gonococcal research. Urethral infection in chimpanzees anatomically resembled the human infection; however, individual variation in response, limited availability, and the presence of interfering micro-organism...

The severity of epidemic and pandemic influenza outbreaks is dictated in part by the efficiency with which the causative strain transmits between human hosts. The mechanisms underlying influenza virus spread are poorly understood, in part because of the lack of a convenient animal model to study this phenomenon. Indeed, despite extremely efficient transmission among humans and virulence in the ...
