The theory of curves has a very long history.Moving frames defined on curves are important parts of this theory.They have never lost their importance.A point particle of constant mass moving along a trajectory in space may be seen as a point of the trajectory.Therefore, there is a very close relationship between the differential geometry of the tra
In the spring of 2000, field experiments were begun on three 20-year old grand fir (Abies grandis) to influence the elasto-mechanical behavior of the stem, as well as the distribution of the assimilate crown production.The aim was to analyze, and then describe and model the expected resulting change in stem growth.Three stem sections of one fir wer
Abstract Hydrothermal biochar has demonstrated potential in enhancing crop growth by improving soil properties and microbial activity; however, its effectiveness varies with application rate, with excessive amounts potentially inhibiting plant growth.This study employed a pot experiment approach to compare varying application rates of hydrothermal
A systematic investigation is still lacking for tension out-of-plane in cross laminated timber (CLT), as a planar timber construction product.The objectives of the present study are the determination of the tensile properties of CLT made of Norway spruce, the identification of essential product-specific influencing parameters and a us polo assn men
