Discharge coefficient of vertical sluice gates with broad crested weir under free-submerged orifice flows using best subset regression

Water Science and Technology
Accurate calculation of flow discharge for sluice gates is essential in irrigation, water supply, and structure safety. The measurement of discharge with the requirement of distinguishing flow regimes is not conducive to application.

In vitro studies to characterise different physico-chemical properties of some feed grains and their impact in monogastric nutrition

Italian Journal of Animal Science, 2021
Characterisation of the variations in physico-chemical properties of grains may help to improve the feeding value of grains for animal nutrition. Thus, this study aimed to obtain more extensive quantitative ideas concerning different physico-chemical ...

Grain sedimentation inside giant planet embryos

, 2010
In the context of massive fragmenting protoplanetary discs, Boss (1998) suggested that grains can grow and sediment inside giant planet embryos formed at R ~ 5 AU away from the star. Several authors since then criticised the suggestion.

Dynamic stereo microscopy for studying particle sedimentation [PDF]

, 2014
We demonstrate a new method for measuring the sedimentation of a single colloidal bead by using a combination of optical tweezers and a stereo microscope based on a spatial light modulator.

Between Droughts and Floods: The Seasonal Response of Freshwater Snails in Artificial Reservoirs in the Brazilian Semiarid Region

Population Ecology, EarlyView.
We investigate the seasonal dynamics of two freshwater snails, Biomphalaria straminea and Melanoides tuberculata, in artificial reservoirs of the Brazilian semiarid region. Despite regulated hydrology, B. straminea exhibited strong seasonal fluctuations associated with dry periods, while M. tuberculata maintained stable populations throughout the year,

Sedimentation of active colloidal suspensions

, 2010
In this paper, we investigate experimentally the non-equilibrium steady state of an active colloidal suspension under gravity field. The active particles are made of chemically powered colloids, showing self propulsion in the presence of an added fuel ...

Hyperuniformity with no fine tuning in sheared sedimenting suspensions [PDF]

, 2018
Particle suspensions, present in many natural and industrial settings, typically contain aggregates or other microstructures that can complicate macroscopic flow behaviors and damage processing equipment.

Infection Models for Pine Wilt Disease on the Basis of Vector Behaviors

Population Ecology, EarlyView.
Infection models for pine wilt disease without vector density were built to estimate the transmission coefficient of the pathogenic nematode. The models successfully simulated the annual change in the density of infected trees for four pine stands. ABSTRACT Pine wilt disease is caused by the pinewood nematode (Bursaphelenchus xylophilus Steiner et ...

Distribution of particle sedimentation thickness under constant relative centrifugal force in rotating separation system using wireless electrical resistance detector

Mechanical Engineering Journal, 2020
The demand for high separation efficiency needs an advanced device that can be installed in the separation machinery. Parameters in the separation system, such as feeding flow rate and rotational speed, influence the sedimentation formation.
