Propagation by Cutting of Grewia coriacea Mast. (Malvaceae)
Pakistan Journal of Biological Sciences, 2015 Congolese forests contain important spontaneous food plants. Among these plants, there is the Grewia coriacea Mast., called in the national language "Tsui-téké", which is a tree of 4-25 m high and of 12-40 cm in diameter. Its fruits are used in several drinks making (juice, sparkling wine, syrup) and lollipops.

Performance Analysis of Abradable Coating Systems for Aircraft Gas Turbines
Advanced Engineering Materials, EarlyView.Three CoNiCrAlY/YSZ/MgAl2O4 abradable liner configurations on a nickel‐superalloy are evaluated by thermal‐gradient cycling and incursion tests. Laser ablation of the bondcoat and/or Y2O3‐stabilized ZrO2 (YSZ) intermediate layer increases mechanical interlocking and bonding for thick topcoats.

Crack propagation in honeycomb cellular materials: a computational approach
, 2012 Computational models based on the finite element method and linear or nonlinear fracture mechanics are herein proposed to study the mechanical response of functionally designed cellular components. It is demonstrated that, via a suitable tailoring of the

Advanced Engineering Materials, EarlyView.A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Methods used in cutting propagation of forest trees in Finland.
Silva Fennica, 1980 Cutting propagation of forest trees has recently been done in Finland mainly by the Foundation for Forest Tree Breeding. The aim has been to develop methods which could be used in forest nurseries for large scale production of rooted cuttings.

Changes in the nutritional constituents in cuttings during propagation
Engei Gakkai zasshi, 1971 1. Changes in nitrogen and carbohydrate contents in hardwood cuttings of grapevines (cv. Delaware) were investigated during propagation.2. Dry weight of a whole cutting continued to decrease gradually through 60 days after planting and thereafter began to increase due to the growth of new shoots. The increase of dry weight in upper and lower half stems

Finite element simulation of crack propagation and delamination in layered shells due to blade cutting [PDF]
, 2016 The focus of this work is on the simulation of crack propagation and delamination in layered shells due to cutting by sharp blades. The main features of these type of problems are: material non-linearities, contact, large deformations, fracture and ...

Advanced Engineering Materials, EarlyView.Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.
