Summary Environmental adaptation and cell differentiation processes are factors that influence the anatomical elements of wood. The objective this study was to investigate effect water deficit on lignin composition in characteristics vessel-neighboring cells. Six-year-old clones Eucalyptus urophylla grandis × camaldulensis from wet dry regions were used. All received a rainfall exclusion treatment. Cell wall width, thickness, form factor fibers close far vessels measured. In same cells,...
The COVID-19 pandemic has brought discussions about the efficacy of respiratory protection equipment, primarily due to their widespread usage during this period. Among various types face masks, N95, PFF3, and PFF2 surgical masks have gained great prominence efficiency, despite discomfort they may cause. Therefore, thinking a cost-effective more comfortable solution, work aimed reinforce non-woven with cellulose nanofibrils (CNFs), improve filtration efficiency. For this, CNFs were produced...
The production of yarns and synthetic fibers is great importance for numerous industrial sectors, such as the textile, composite material, biomedical, civil construction industries. utilization cellulose microfibrils (CNFs) filament still requires further research, given challenges associated with coagulation process. Extensive research efforts have been dedicated to development materials that can be combined CNFs improve coagulation. This study aimed develop an acetone spinning method...
Background: Multiple challenges are faced by industry and certification agencies when commercializing tropical species. Anatomical similarities of hardwoods impair identification. Deep learning models can facilitate microscopic identification wood using sophisticated techniques such as deep convolutional networks (DCNN). Our objective was to microscopically identify 23 commercially available Brazilian species a custom DCNN model. Results: Photographs from slides each were processed, the...
The aim was to assess the effect of sawing patterns on lumber yield, energy consumption, and surface quality Pinus caribaea var. wood sawn a portable sawmill. logs had an average diameter 29 cm, length 3 m, age 46 years. A specific pattern used for production cants boards another two-sided cants, obtained after subsequent edging operation. Log board volumes were determined, ratio these variables calculate yield. amount during breakdown determined by measuring electric current applied time...
