Abstract Recent applications of digital photogrammetry in forestry have highlighted its utility as a viable mensuration technique. However, tropical regions little research has been done on the accuracy this approach for stem volume calculation. In study, performance Structure from Motion estimating individual tree relation to traditional approaches was evaluated. We selected 30 trees five sava...

The relevance of the study is related to need determine current state windbreaks as a component forest-agrarian landscape particular region. purpose conduct comprehensive assessment windbreaks. During study, data from remote sensing Earth using satellite imagery was utilised, which allowed for determining field parameters, placement windbreak system, and their characteristics. Forest inventory ...

AIMS The purpose of this study was to investigate the protective effects of sericin protein (SP) on alcohol-induced hepatic injury in mice and the possible mechanisms. METHODS SP (0.375, 0.75 and 1.50 g/kg body weight) was dissolved in distilled water and given to mice by gavage 1 hour before the alcohol (56% wt/vol, 14.2 ml/kg b.w.) treatment for 30 days, then blood, urine and liver were col...

The article introduces an atlas-assisted method and a tool called the Cerefy Neuroradiology Atlas (CNA), available over the Internet for neuroradiology and human brain mapping. The CNA contains an enhanced, extended, and fully segmented and labeled electronic version of the Talairach-Tournoux brain atlas, including parcelated gyri and Brodmann's areas. To our best knowledge, this is the first o...

Forest carbon sequestration offset protocols have been employed for more than 20 years with limited success in slowing deforestation and increasing forest trading volume. Direct measurement of flux improves quantification but has not applied to research projects 600 site installations worldwide. In this study, we apply accounting methods, scaling hours decades 28-years scientific CO2 eddy covar...

The treatment of tuberculous disease of the hip in children has not yet reached the stage when useful recovery of joint function is a frequent end-result. Brackett (1924) urged that the first objective should be the provision of a permanently safe and useful limb; and in girls, we would add, a graceful one. These standards are not achieved, even with quiescent disease and a soundly ankylosed jo...

Mensuration of tree growth habits is of considerable importance for understanding forest ecosystem processes and forest biophysical responses to climate changes. However, the complexity of tree crown morphology that is typically formed after many years of growth tends to render it a non-trivial task, even for the state-of-the-art 3D forest mapping technology-light detection and ranging (LiDAR)....
