abstract aim and background: the zuckerman – kuhlman personality questionnaire is an instrument measuring personality traits. it is designed according to zuckerman’s alternative five factor personality model (ffm). the present research aimed at investigating the psychometric properties of a version of the zuckerman – kuhlman personality questionnaire which contains 50 items. method and material...

Sensation seeking is a core personality trait that declines with age in both men and women, as do also both density and availability of the dopamine D(2/3) receptors in striatum and cortical regions. In contrast, novelty seeking at a given age relates inversely to dopamine receptor availability. The simplest explanation of these findings is an inverted-U-shaped correlation between ratings of se...

The breakthrough result of Chattopadhyay and Zuckerman (2016) gives a reduction from the construction of explicit two-source extractors to the construction of explicit non-malleable extractors. However, even assuming the existence of optimal explicit nonmalleable extractors only gives a two-source extractor (or a Ramsey graph) for poly(logn) entropy, rather than the optimal O (logn). In this pa...

OESTROGENIC substances can be recovered from the ovaries, placenta, urine, blood, faeces, bile, colostrum, testes, adrenals and pituitary [Doisy, 1932; Callow & Parkes, 1936]. Until recently there has been no evidence of their presence in tissues on which they specifically act. The present paper is an account of their occurrence in the sexual skin of monkeys, a tissue whose activity, it has bee...

Semi-infinite forms on the moduli spaces of genus-zero Riemann surfaces with punctures and local coordinates are introduced. A partial operad for semi-infinite forms is constructed. Using semi-infinite forms and motivated by a partial suboperad of the partial operad for semi-infinite forms, topological vertex partial operads of type k < 0 and strong topological vertex partial operads of type k ...

Zuckerman, Tsiquaye, and Fulton in 1967 described a method for the cultivation of monolayers of differentiated parenchymal human embryonic liver cells in glass tissue culture plates made especially for this purpose. The apparatus utilized and the precise method of implantation are given in detail by Fulton (1960). This technique was later modified and extended to the culture of very small fragm...
