SIZE STRUCTURE IN SETTLEMENTS OF MUSSEL CRENOMYTILUS GRAYANUS AT THE COAST OF PRIMORSKY KRAI (JAPAN SEA)

open access: yesИзвестия ТИНРО, 2019
Current size structure of mussel Crenomytilus grayanus in the coastal waters at Primorye (Japan Sea) is considered on results of diving surveys conducted in 2003–2018. In total, 3635 mussel specimens were weighed and measured.

Meta-Estimation of Araucanian Herring, Strangomera bentincki (Norman, 1936), Biological Indicators in the Central-South Zone of Chile (32°–47° LS)

open access: yesFrontiers in Marine Science, 2022
Araucanian herring, Strangomera bentincki, is ecologically and economically important. Its complexity, like that of other pelagic fish, arises from seasonal population changes related to distribution with different spatial dynamics and demographic ...

Yield stress fluids method to determine the pore size distribution of a porous medium [PDF]

open access: yes, 2014
In this paper a new method is presented in order to determine the pore size distribution in a porous medium. This original technique uses the rheological properties of some non-Newtonian yield stress fluids flowing through the porous sample.

The Size and Structure of Government [PDF]

open access: yesSSRN Electronic Journal, 2010
Does government size and structure adapt to changes in government’s organisational environment (particularly to uncertainty and complexity) as predicted by organisational theory? We find – using a range of statistical analyses – support for each of the major theories of organisation adaptation (the contingency-based view, resource-based view, and ...

Inapparent decrease in phytoplankton biomass accompanied by significant size composition succession in the shellfish aquaculture farm in the western Taiwan strait

open access: yesFrontiers in Marine Science, 2023
We conducted an annual monthly sampling in the aquaculture areas of Lianjiang and Zhangpu, Fujian province, in the west coast of the Taiwan Strait, to gain insight into the effects of shellfish aquaculture on total phytoplankton biomass and its ...

Effect of Anthropogenic Aerosol Addition on Phytoplankton Growth in Coastal Waters: Role of Enhanced Phosphorus Bioavailability

open access: yesFrontiers in Microbiology, 2022
Atmospheric deposition can supply nutrients to induce varying responses of phytoplankton of different sizes in the upper ocean. Here, we collected surface and subsurface chlorophyll a maximum (SCM) seawaters from the Yellow Sea and East China Sea to ...

Optimal harvesting in a unidirectional consumer–resource mutualisms system with size structure in the consumer

open access: yesNonlinear Analysis, 2022
This paper considers the optimal harvesting problem for a size-structured model of unidirectional consumer–resource mutualisms in which the consumer species has both positive and negative effects on the resource species, while the resource has only a ...

The size effect in concrete structures

open access: yes, 1993
In the present paper the results of a size effect study on plain concrete unnotched and notched beams loaded in three-point bending are shown and compared with experimental results and Bazant's size effect law. The numerical results, obtained using the nonlocal microplane finite element code, confirm a strong size effect for smaller beam sizes. However,

Investigating and modelling the body size structure of benthic communities [PDF]

open access: yes, 2006
Benthic communities were investigated in terms of their body size distributions at three environmentally contrasting study sites: (i) a shallow-water location on the Fladen Ground, North Sea, (ii) a deep-water location in the Faroe-Shetland Channel and ...
