The photosynthetic activities, the pigmentation and the chloroplast
membrane polypeptides of several mutants of the green alga, Scenedesmus
obliquus, with complete or limited deficiencies in the light-harvesting
complex of photosystem II are characterized and compared to those of the
normal phenotype.. The principal phenotype examined in this study, K0 -9,...
In vivo generation of cytotoxic T cell activity
against alloantigen is suppressed by the aromatic
hydrocarbon (Ah) receptor binding 3,3',4,4',5,5'-
hexachlorobiphenyl isomer (HxCB). Previous studies in
this laboratory suggest that HxCB may alter early
event(s) in the activation of cytotoxic T lymphocytes
(CTL). Production of and response to interleukins 1...
The western North Atlantic population of the northern right whale (Eubalaena
glacialis) was severely depleted by whaling over the last century. Despite over fifty
years of protection, fewer than four hundred individuals are believed to exist in the
North Atlantic. Relatively little is known about the diving behavior, respiratory
physiology,...
This phenomenological study explores what it means to teach part-time in community colleges in the United States. The increasing use of part-time faculty in community colleges and the concomitant emergence of a two-tiered faculty are discussed.
The study examines the nature of part-time work in the United States, thus providing...
Children who have multiple family risk factors are at increased risk for poor developmental outcomes, including poor academic achievement. The present study focused on charting the pathways through which early family risk – as indexed by ethnic minority status, low maternal education, low family income, and chronic maternal depressive symptoms...

In 2013, Lemke Oliver created a list of all eta-quotients which are theta functions. Then in 2016, Folsom, Garthwaite, Kang, Swisher, and Treneer utilized this list of ``eta-theta'' functions along with Zwegers's construction of mock theta functions to create a set of mock modular forms which are also quantum modular...
In this paper the authors investigate the action of ambient turbulence on thermohaline interleaving using both theory and numerical calculations in combination with observations from Meddy Sharon and the Faroe Front. The highly simplified models of ambient turbulence used previously are improved upon by allowing turbulent diffusivities of momentum, heat,...
We have previously shown that relative potency factors and DNA adduct measurements are inadequate for predicting carcinogenicity of certain polycyclic aromatic hydrocarbons (PAHs) and PAH mixtures, particularly those that function through alternate pathways or exhibit greater
promotional activity compared to benzo[a]pyrene (BaP). Therefore, we developed a pathway
based approach for...
