The reduction of resinous species in Portuguese forest areas has caused constraints to wood industry supplies. Portugal represents the extreme southwest Scots pine (Pinus sylvestris) natural distribution and large gaps exist knowledge its wood-quality characteristics. Understanding relationship between these traits is important for recognizing which combination properties most suitable specific uses. To address questions, we assessed traits, namely, wood-density components...
A cirurgia robótica tem avançado significativamente, proporcionando maior precisão e eficiência em procedimentos cirúrgicos. Esta revisão examina evidências recentes sobre a tecnologia robótica, destacando seus benefícios limitações. demonstra melhora na precisão, redução da perda de sangue aceleração recuperação pós-operatória. Procedimentos como o reparo robótico hérnia inguinal pancreatoduodenectomia têm mostrado taxas mais baixas complicações melhor comparados às abordagens tradicionais....
The maritime pine (Pinus pinaster) is the main conifer species in Portugal, occurring mainly central and northern regions of country. In addition to its environmental significance, it plays an important socio-economic role, supported by a robust forest sector. face climate change driven release CO2 into atmosphere, forests play essential role mitigating these changes storing large amounts carbon their biomass. This study assesses impact management, focusing on thinning, accumulation...
This study contributes to the Pinus pinaster Ait. breeding programme, which is reaching third generation by adding information on wood quality of 46 open-pollinated families from a progeny trial located in Leiria, Portugal, that originated seed collected clonal orchard. A total 552 seventeen-year-old trees were sampled at 2 m height. Trends studied pith outward variance components and narrow-sense heritability (h ) density ring-width characteristics as well genetic correlations between...
The forest inventory plays a crucial role in management planning, and it is the first step planning actions for production. However, conducting an can be expensive complex. Forest applications on smartphones have emerged as alternative to traditional methods they aim make field data collection more accessible non-professionals while ensuring accuracy determining volume of wood given area. This study evaluates effectiveness Katam, Arboreal, Trestima compared methods. focuses assessing stand...
The maritime pine (Pinus pinaster Ait.) forest is an essential element of the Portuguese landscape due to its social, economic, and environmental importance. sustainability these forests in Mediterranean region faces challenges recurrent fires absence or delayed management. species has a high capacity for regeneration, but perpetuation sustainable conditions depends on adequate management achieve biomass production assure fire resilience. This study aimed analyse four scenarios (C1 C4)...
Abstract Cork oak ( Quercus suber L.) grows in the Mediterranean basis including Portugal and is main species producing cork which used prevailingly stopper industry. In our paper, from L. over three consecutive harvests a traditional rainfed plot, between 1999 2017, an irrigated harvested were studied. We applied two X–ray image analysis technologies – micro-computed tomography microdensitometry. development, related with intern porosity, growth density was studied objective of...
In order to characterise the changes produced by boiling and roasting on mechanical properties of 11 Portuguese chestnut cultivars (cvs.), moisture, mass, force energy required as well shell kernel stiffness raw, boiled roasted chestnuts were evaluated. comparison raw chestnuts, increased moisture content about 4% decreased 20%. Lamela Judia cvs. more rupture shell, while Negra Boaventura kernels offered higher resistance penetration. Colour was also evaluated because it is a parameter that...
The northern inland region of Portugal has experienced significant population decline due to the exodus younger generations and an aging population. This led abandonment traditional activities in these territories, contributing territorial abandonment, degradation local economic conditions, increased social vulnerability, a heightened risk rural fires. presence communal lands, known as “baldios”, is important facilitator for implementing actions that revitalize villages, making them more...
Quercus rotundifolia Lam., known as holm oak or evergreen oak, occurs naturally in the western Mediterranean region, mainly part of agroforestry agrosilvopastoral systems Portugal (“montado”) and Spain (“dehesa”), is economically important for acorn production. Less attention has been given to Q. wood, its density variability not known, namely related tree growth. The wood 20 trees was measured along radial direction by X-ray densitometry factors responsible ring width variation within...
Environmental conditions can change both the quantity and quality of wood formation. This study aimed to evaluate anatomical chemical changes in a Eucalyptus urophylla S.T. Blake clone cultivated four sites wide climatic Brazil. Radial samples were used xylem anatomy along growth cycles. Samples with quarter disk perform analyses extractives, total lignin (LG), syringyl/guaiacyl (S/G), holocellulose, elemental analysis wood. The elements Na, K, Ca, Mg, P, Mn, Fe, Zn, Ni, Cu, Cr, Cd, F, Cl...
This paper aimed to determine the quality indexes for and cellulose based on fiber features from two wood species of interest, Eucalyptus pellita E. tereticornis. The mean annual increment (IMA) was calculated by measuring DBH Height (25 years), a 10 cm disk each tree collected density determinations anatomical studies paper. Tree height, trunk diameter at 1.30 m in height (DBH), volume per were higher when compared hectare average tereticornis pellita. Based dimensions, we did not observe...
