Influence of pre-drilling hole and feed rate on welded surface strength of pine-itauba joints

open access: yesCase Studies in Construction Materials, 2022
Rotary friction welding technique is a promising alternative of joining dowel-laminated timber (DLT) and dowelled cross-laminated timber (DCLT), without any adhesive.

Crown Efficiency and Pine Cones Production for Brazilian Pine (Araucaria angustifolia (Bertol.) Kuntze) in South Brazil

open access: yesJournal of Agricultural Science, 2019
Crown efficiency is a relation of growth with the area tree occupies (available area efficiency). Efficiency is associated with the vertical and lateral expansion capacity of the tree and crown, increase, density and light absorption. Thus, our study aimed to evaluate crown efficiency with pine cones∙tree-1 production and dendro/morphometric variables ...

Elucidation of the polyamine biosynthesis pathway during Brazilian pine (Araucaria angustifolia) seed development [PDF]

open access: yesTree Physiology, 2017
Polyamines (PAs), such as spermidine and spermine, as well as amino acids that are substrates for their biosynthesis, are known to be essential for plant development. However, little is known about the gene expression and metabolic switches associated with the ornithine/arginine and PA biosynthetic pathway during seed development in conifers.

Development of a “pinhão” (brazilian pine nut) peeling machine

open access: yes, 2019
Resumo - A cadeia produtiva do pinhão envolve as etapas de colheita, descasque, industrialização e comercialização. Uma das dificuldades encontradas é a falta de equipamento capaz de descascar o produto, aumentando a capacidade de trabalho da atividade. O descascamento é um processo demorado e difícil, necessitando de intensa mão-de-obra. Este trabalho

Exchange Rates and Sovereign Risk: A Nonlinear Approach Based on Local Gaussian Correlations

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT We empirically assess the interlinkages between sovereign risk, measured in terms of CDS spreads, and exchange rates for a sample of emerging markets. Our period of analysis includes episodes of severe stress, such as the Global Financial Crisis, the COVID‐19 pandemic, and the Ukrainian War.

Low‐Dose Chlorothalonil Induces Testicular Injury Through Disruption of Steroidogenic Signaling in Adult Male Mice

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Chlorothalonil (CHL) is a widely used organochlorine fungicide frequently detected in environmental and food matrices. Although increasing evidence indicates adverse effects in nontarget species, the mechanisms underlying CHL‐induced male reproductive toxicity remain incompletely understood.

Using crown characterisation variables as indicators of the vigour, competition and growth of Brazilian pine

open access: yesSouthern Forests: a Journal of Forest Science, 2021
Crown variables are used in growth and production models to increase the accuracy of estimates. These variables are costly and difficult to measure, mainly in dense native forests such as mixed ombrophilous forests (MOF), where Araucaria angustifolia is the predominant species.

Irritability in preschool children with attention‐deficit/hyperactivity disorder: Analysis of family environmental factors

open access: yesJCPP Advances, EarlyView.
Abstract Background Irritability affects one‐third of children and adolescents with attention‐deficit/hyperactivity disorder (ADHD) and is associated with negative outcomes. The family environment plays a prominent role in the child's development, and therefore on the risk for irritability, especially during the preschool period.
