Size and Composition of the MORB+OIB Mantle Reservoir

open access: yesGeochemistry, Geophysics, Geosystems, 2022
Most efforts to characterize the size and composition of the mantle that complements the continental crust have assumed that the mid‐ocean ridge basalt (MORB) source is the incompatible‐element depleted residue of continental crust extraction. The use of

Group Divisible Codes and Their Application in the Construction of Optimal Constant-Composition Codes of Weight Three [PDF]

open access: yes, 2008
The concept of group divisible codes, a generalization of group divisible designs with constant block size, is introduced in this paper. This new class of codes is shown to be useful in recursive constructions for constant-weight and constant-composition

Proximate composition and serving sizes of selected composite Ghanaian soups

open access: yesAfrican Journal of Food, Agriculture, Nutrition and Development, 2020
Soups are major components of Ghanaian dishes. The composite nature of Ghanaian soups, in general, tend to make the calorie and macronutrient composition highly variable. This study sought to determine the proximate composition of selected Ghanaian soups from defined recipes and to photographically present quantities of the soups, measured with common ...

Dynamics of fishery and distribution of aggregations for saffron cod Eleginus gracilis (Tilesius) at northern Kuril Islands

open access: yesИзвестия ТИНРО
The fishery on winter-spring accumulations of saffron cod in the area of northern Kuril Islands has a long history with varying intensity, though this species is not abundant both in the Pacific and Okhotsk Sea waters of this area.

Fission-fusion dynamics and group-size dependent composition in heterogeneous populations

open access: yes, 2019
Many animal groups are heterogeneous and may even consist of individuals of different species, called mixed-species flocks. Mathematical and computational models of collective animal movement behaviour, however, typically assume that groups and ...

Current state for stocks and fishery of saffron cod Eleginus gracilis (Tilesius, 1810) in the western Bering Sea

open access: yesИзвестия ТИНРО
State of stocks and fishery and some general features of biology are considered for saffron cod in the Bering Sea on results of bottom trawl surveys and commercial fishery statistics in 2000–2023. In 2023, the stock in the southwestern part of the sea is

A global perspective on household size and composition, 1970–2020

open access: yesGenus
Households are core units of social organization and reproduction, yet, compared to other areas of demographic research, we have limited understanding of their basic characteristics across countries.

Associations between Childhood Body Size, Composition, Blood Pressure and Adult Cardiac Structure: The Fels Longitudinal Study

open access: yesPLoS ONE, 2014
Objectives To determine whether childhood body size, composition and blood pressure are associated with adult cardiac structure by estimating childhood “age of divergence.” Methods 385 female and 312 male participants in the Fels Longitudinal Study had ...
