Hop (Humulus lupulus L. var lupulus) is a plant of great cultural significance, used as a medicinal herb for thousands of years, and for flavor and as a preservative in brewing beer. Studies of the medicinal effects of the unique compounds produced by hop have led to interest from the...
Under defined cultural conditions, large populations of zygotes
of the brown algae Fucus vesiculosus L. and F. distichus L. Powell
synchronously form a cell wall shortly after fertilization. Intact cell
walls, free of cytoplasm and maintaining shape properties of early
stages of embryo development, have been isolated from these zygotes....
Draft membership agreements for pollock fishery cooperatives pay particular attention to the allocation of quota among cooperative members. Since the impetus for cooperative organization among pollock fishing boats derives largely from the opportunity provided by transferable quotas, this emphasis is not surprising. However, a cooperative structure requires attention to other...
In the 1990s, Bartlett and Youd introduced empirical equations for predicting
horizontal displacement from liquefaction-induced lateral spreading; these equations have
become popular in engineering practice. The equations were developed by multilinear
regression (MLR) of lateral spreading case history data compiled by these researchers. In 2002,
these equations were revised and...
Brazil's economic strategy has shifted hesitatingly during the last several decades from one of producer protection to trade competitiveness. Exploiting the variations these shifts have afforded, we use a sequence of decennial agricultural censuses to examine Brazilian policy implications for agricultural competitiveness and efficiency. Total factor productivity is decomposed into...
Larval supply determines year-class strength of fisheries and complex ecological
interactions among adults of benthic marine species. In upwelling regions, a latitudinal cline in
the intensity and persistence of upwelling is thought to affect larval advection and recruitment,
thereby regulating the intensity of interactions in adult populations and communities. We...
