Patient-reported outcomes, postoperative pain and pain relief after day-case surgery (POPPY): baseline data from day surgery practice in the UK. [PDF]

open access: yesAnaesthesia
Summary Introduction Most patients undergoing elective surgery in the UK are discharged from hospital on the same day. Despite this, there is a lack of UK patient‐centred outcome measures relating to quality of recovery, pain and analgesic use. The POPPY study was a UK‐wide prospective, observational study measuring short‐ and longer‐term patient ...

Verification of two- and three-parameter simple height-diameter models for birch in the European part of Russia

open access: yesJournal of Forest Science, 2020
The accuracy of determining the height of trees is essential both in forestry and in scientific research. Height is usually determined using specific models, where it is a function of the diameter at breast height.

EVALUATION OF SITE QUALITY AND MODELLING TREE PRODUCTIVITY BY LIDAR TECHNOLOGY IN SALT-AFFECTED OAK FOREST TERRITORY [PDF]

open access: yesNatural Resources and Sustainable Development, 2019
Forest site quality evaluation is an important part of forest planning and forest management. A forest site is characterized by forest biomass, which is determined by elevation characteristics, soil type and climate.

Osteology of the Feeding Apparatus of Chilean Flamingo Phoenicopterus chilensis (Aves: Phoenicopteridae). [PDF]

open access: yesJ Morphol
1. The skull features a broad, dorsoventrally flattened frontal region articulating with an elongated upper jaw that is complemented by the mandible's downward bend along its proximal half. 2. The low mechanical advantage in the mandible is attributed to the reduced and shallow insertion areas of the adductor muscles, which are positioned close to the ...

Engelmann spruce site index models: a comparison of model functions and parameterizations.

open access: yesPLoS ONE, 2015
Engelmann spruce (Picea engelmannii Parry ex Engelm.) is a high-elevation species found in western Canada and western USA. As this species becomes increasingly targeted for harvesting, better height growth information is required for good management of ...

GROWTH OF AMAZON NATIVE SPECIES SUBMITTED TO THE PLANTATION IN THE RORAIMA STATE

open access: yesCiência Florestal, 2009
An important forest research challenge in the Amazonian is finding forms of reforesting degraded areas with the use of a larger number of native species and identify tropical species commercially attractive adapted to clear-cut areas.

Height–diameter modeling of tree species in boreal and mixed forests using a mixed-effects approach and stand-level variables

open access: yesForest Science and Technology
Forests are ecologically complex, and trees play a structural and functional role in ecosystem dynamics. Tree height–DBH (diameter at breast height) relationships serve as a key indicator of forest productivity, competition, and succession, fundamental ...
