The effect of pallet top deck stiffness on the compression strength of asymmetrically supported corrugated boxes

open access: yesPackaging technology & science, 2020
During unitized shipment, the components of unit loads are interacting with each other. During floor stacking of unit loads, the load on the top of the pallet causes the top deck of the pallet to bend, which creates an uneven top deck surface resulting ...

Static compression of porous dust aggregates [PDF]

open access: yes, 2013
Context: In protoplanetary disks, dust grains coagulate with each other and grow to form aggregates. As these aggregates grow by coagulation, their filling factor \phi decreases down to \phi 0.1).

An Injectable Enzymatically Crosslinked and Mechanically Tunable Silk Fibroin/Chondroitin Sulfate Chondro‐Inductive Hydrogel

open access: yesMacromolecular Materials and Engineering, 2023
An injectable hybrid hydrogel is synthesized, comprising silk fibroin (SF) and chondroitin sulfate (CS) through di‐tyrosine formation bond of SF chains. CS and SF are reported with excellent biocompatibility as tissue engineering scaffolds.

Effect of growth conditions on wood properties of Scots pine (Pinus sylvestris L.)

open access: yesMetsanduslikud Uurimused, 2022
The study material of Scots pine sample trees originated from five different forest site types (Cladonia, Calluna, Myrtillus, natural raised bog and drained raised bog) in Estonia. Altogether, 60 trees were sampled from 10 stands.
