Carapace length-frequency distribution and carapace length-weight correlation of ornate spiny lobster (Panulirus ornatus) in Sebatik Island Waters – Indonesia [PDF]

open access: yesE3S Web of Conferences, 2021
Ornate spiny lobster (Panulirus ornatus) in Sebatik Island is a commercial fisheries commodity that has the highest price if we compare it with another lobster caught by the fisherman in Sebatik Island Waters. That causes the effort to catch this lobster

Research of the petroleum road bitumen modification process with secondary polyethylene terephthalate [PDF]

open access: yesE3S Web of Conferences, 2023
Modification of bitumen with polymers is an effective way to improve its properties. Despite the sufficiently widespread use of this method, currently there are practically no appropriate methods of this process calculation. Moreover, there are almost no

Black Carbon Aerosols in the Lower Free Troposphere are Heavily Coated in Summer but Largely Uncoated in Winter at Jungfraujoch in the Swiss Alps

open access: yesGeophysical Research Letters, 2020
Black carbon (BC) particles are responsible for substantial radiative heating of the atmosphere. However, the climate‐relevant properties of BC particles in the free troposphere (FT) are poorly constrained over longer time scales.

Comparison of alumina ball size distribution in two white cement grinding units using Swebrec function

open access: yesDyna, 2019
The results of characterizing the alumina ball size distribution in two mills of a crushing and grinding plant are shown. The mills were unloaded and the ball charge was screened in order to establish the ball size distribution. For both mills, the balls

Deciphering the Relationship Between Free and Vesicular Hemoglobin in Stored Red Blood Cell Units

open access: yesFrontiers in Physiology, 2022
Red blood cells (RBCs) release hemoglobin (Hb)-containing extracellular vesicles (EVs) throughout their lifespan in the circulation, and especially during senescence, by spleen-facilitated vesiculation of their membrane.
