An empirical equation for shear viscosity of shear thickening fluids

open access: yesJournal of Molecular Liquids, 2021
Quantitative modelling of the rheology of non-Newtonian fluids requires significant empirical input due to very complex behaviour of the bulk fluid as a result of particle-scale physics of fluids.

The unusual occurrence of tricolpate pollen within Mutisieae (Asteraceae) [PDF]

open access: yes, 2019
The monotypic genus Hecastocleis and species of Ainsliaea DC. (Asteraceae, Mutisieae) have tricolpate pollen, which is unusual in Asteraceae. The pollen morphology of H.

Morfología polínica de las Proteaceae nativas de Argentina: una nueva clave dicotómica para su identificación [PDF]

open access: yes, 2017
A dichotomous key for the identification of eight proteaceous species, native to Argentina, based on pollen morphology is presented. These species are: Embothrium coccineum, Gevuina avellana, Lomatia dentata, L. ferruginea, L.

Impact characteristics of soft composites using shear thickening fluid and natural rubber–A review of current status

open access: yes, 2021
The main focus of this review is on soft composites, relatively new to the literature. The ballistic fabrics, mechanism of ballistic energy absorption and parameters affect the ballistic performance of fabrics are reviewed. Adding shear thickening fluid (

K-Ar dated palynofloras in Tasmania 1: Early Oligocene, Proteacidites tuberculatus Zone sediments, Wilmot Dam, northwestern Tasmania [PDF]

open access: yes, 1994
Tertiaty lake sediments at Wilmot Dam, northwestern Tasmania, are dated as Lower Proteacidites tuberculatus Zone, based on the palynological zonation developed for the Gippsland Basin in eastern Bass Strait.

Poor Correlation between Diaphragm Thickening Fraction and Transdiaphragmatic Pressure in Mechanically Ventilated Patients and Healthy Subjects

open access: yesAnesthesiology, 2021
Background: The relationship between the diaphragm thickening fraction and the transdiaphragmatic pressure, the reference method to evaluate the diaphragm function, has not been clearly established.

Morphological study of the genus Classopollis (Pflug) Pocock & Jansonius (Cretaceous, Argentina) [PDF]

open access: yes, 2014
The present paper analyses different species belonging to the genus Classopollis (Pfl ug) Pocock & Jansonius with scanning electron microscopy (SEM). The material was collected from surface sections and boreholes of Cretaceous age located in Santa Cruz ...

Soil penetration by maize roots is negatively related to ethylene‐induced thickening

open access: yesPlant, Cell and Environment, 2021
Radial expansion is a classic response of roots to a mechanical impedance that has generally been assumed to aid penetration. We analysed the response of maize nodal roots to impedance to test the hypothesis that radial expansion is not related to the ...

Lectin receptor kinase OsLecRK‐S.7 is required for pollen development and male fertility

open access: yesJournal of Integrative Plant Biology, Volume 62, Issue 8, Page 1227-1245, August 2020., 2020
By isolating a recessive mutant gene responsible for a complete male sterile phenotype, we identified the first legume‐lectin receptor kinase in rice, OsLecRK‐S.7, with a function in regulating pollen exine assembly and aperture development. OsLecRK‐S.7 required the kinase activity for its gene function. Abstract Pollen grains are covered by exine that
