Mass loss and stellar superwinds [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2017
Mass loss bridges the gap between massive stars and supernovae (SNe) in two major ways: (i) theoretically, it is the amount of mass lost that determines the mass of the star prior to explosion and (ii) observations of the circumstellar material around SNe may teach us the type of progenitor that made the SN.

Partitioning Recent Greenland Mass Loss [PDF]

open access: yesScience, 2009
GRACE and Movement Together Recent measurements of the rate of mass loss from the Greenland ice sheet vary approximately by a factor of three. Resolving these discrepancies is essential for determining the current mass balance of the ice sheet and to project sea level rise in the future. Van den Broeke

Mass loss rates and the mass evolution of star clusters

open access: yesMonthly Notices of the Royal Astronomical Society, 2010
We describe the interplay between stellar evolution and dynamical mass loss of evolving star clusters, based on the principles of stellar evolution and cluster dynamics and on a grid of N-body simulations of cluster models. The cluster models have different initial masses, different orbits, including elliptical ones, and different initial density ...

Pre-competition body mass loss characteristics of Brazilian jiu-jitsu competitors in the United Kingdom [PDF]

open access: yes, 2021
Background: Brazilian jiu-jitsu (BJJ) is a grappling-based combat sport in which competitors engage in pre-competition acute ‘weight’ loss (AWL) and rapid ‘weight’ loss (RWL) to achieve the body mass (BM) required for their desired division.

Experimentally evaluation of high-performance concrete mixes used for tunnels and containing silica fume and polypropylene fiber after exposed to high temperatures

open access: yesFracture and Structural Integrity, 2022
This work introduces an experimental study to evaluate the effect of elevated temperatures on the mechanical properties of high-performance concrete (HPC) mix with changes in Water-Cementitious ratios, W/(C+SF), Silica Fume percent, SF, and Polypropylene,

Mass Loss and Mass Transfer in Algols [PDF]

open access: yesSymposium - International Astronomical Union, 1980
We have examined the observational data of 60 Algols in order to check some theoretical views on mass loss and mass transfer in Algols. Not negligible contradictions between some theoretical non-conservative attempts and the observational scenario have been emphasized.

Pore pressure evolution and mass loss of broken gangue during the seepage [PDF]

open access: yesRoyal Society Open Science, 2018
Broken gangue consists of different particles, and it has more complicated seepage characteristics than intact rock sample. Using the self-designed instrument, the permeability, mass loss and pore pressure of crushed gangue during the seepage are tested.

Calidad postcosecha de genotipos de fresa (Fragaria × ananassa (Duchesne ex Weston) Duchesne ex Rozier) según vernalización

open access: yesActa Agronómica, 2018
La producción de frutilla en Paraguay es realizada por pequeños productores, usando escasa tecnología y obtención de baja productividad, con la necesidad de ampliar los genotipos y la tecnología utilizada. El objetivo de esta investigación fue evaluar la

Ability of selected wood-inhabiting fungi to degrade in vitro sapwood and heartwood of Nothofagus pumilio

open access: yesLilloa, 2022
Fungi are the main decomposers of lignocellulose in temperate forests, and are classified as either white- or brown-rot, based on the ability to degrade lignin along with cellulose and hemicellulose. In this work, decomposition of Nothofagus pumilio wood
