We extend the idea of bilateral determinism of a free Z-action by D. Ornstein and B. Weiss to a free Z²-action. We show that we have a 'stronger' spatial determinism for Z²-actions: to determine the complete Z²-name of a point, it is enough to know the name of a fraction...
Objective: The study aimed to (i) segment parents of early adolescents into subgroups according to their Ca-rich-food (CRF) practices and perceptions regarding early adolescent CRF intake and (ii) determine whether Ca intake of parents and early adolescents differed by subgroup.
Design: A cross-sectional convenience sample of 509 parents and their...
Egg fat is of considerable importance in the nutrition of the developing chick as a source of energy and essential fatty acids such as linoleic (18:2 n-6) and α-linolenic (18:3 n-3) acids. During incubation, yolk lipids provide fatty acids that are utilized for energy, synthesis of polyunsaturated fatty acids (PUFA)-rich...
Alongshore flow in the direction of propagation of coastal trapped waves can result in upwelling at the shelfbreak. The intensity of this upwelling can be comparable in magnitude to wind-driven coastal upwelling, with its associated ecological features. Recent numerical experiments by Matano & Palma indicate that this upwelling results from...
The Taylor–Goldstein (T–G) equation is extended to include the effects of small-scale
turbulence represented by non-uniform vertical and horizontal eddy viscosity and
diffusion coefficients. The vertical coefficients of viscosity and diffusion, A[subscript V] and K[subscript V],
respectively, are assumed to be equal and are expressed in terms of the buoyancy...
Pb-isotope data on ore galenas from the West Shropshire orefield show a significant spread of ²⁰⁶pb/²⁰⁴pb values, with minor variation in ²⁰⁷Pb/²⁰⁴Pb and ²⁰⁸Pb/²⁰⁴Pb ratios. These indicate that lead was derived from multiple sources, some of them uranium-enriched and incompletely mixed prior to ore deposition. Four possible mineralizing agents are...
Crystal rich (~ 70–98% phenocrysts) magmatic inclusions in pumices for compositionally heterogeneous ignimbrites from the Central Andes of northern Chile are interpreted as the products of crystal accretion at the sidewalls of the magma chambers. The inclusions are typically andesitic in composition and are found as ‘peppery textured’ lenses and...
The Llanrwst Pb–Zn veinfield occupies fractures in an Ordovician volcano-sedimentary sequence, with three separate mineralizing events (M₁, M₂ and M₃). The Llanfair Pb–Zn–Cu veinfield consists of sporadic mineralization in Silurian sediments. Fluid inclusion data from both veinfields indicate mineralization took place from CaCl₂-bearing brines, up to 26 wt % NaCl...
High pressure processing was investigated for controlling Cheddar cheese ripening. One-month- or 4-month-old Cheddar cheeses were subjected to pressures ranging from 200 to 800 MPa for 5 min at 25 °C. The number of viable Lactococcus lactis (starter) and Lactobacillus (nonstarter) cells decreased as pressure increased. Subsequent storage of the...
Poetry in the People's Republic of China during the past 30 years has been dominated by works intensely political in nature – a kind of poetry known by the name zhengzhi shuqing shi (political lyric). The function of this poetry was to eulogize current political movements and to generate public...
