introduction : to achieve success in treatment, one cannot ignore the knowledge of pulp anatomy. mandibular premolars are considered to be the most difficult teeth for endodontic therapy due to high variability in their canal morphology. it is possible that a relation exists between the crown size and the number of extra canals in these teeth, so this in vitro study aims to investigate the rela...

Daily and seasonal net photosynthesis (Anet), transpiration (E), absorbed photosynthetically active radiation (Qa) and light-use efficiency (epsilonc) in a red maple container nursery were simulated with MAESTRA, a three-dimensional canopy model. Effects of canopy heterogeneity were simulated by imposing changes in crown spacing. The light transfer sub-model, a distribution model of incident, d...

A method to measure tree crown dimensions is introduced in this article. The method is based on terrestrial images, which are captured from two different directions. Image orientation is registered during the image acquisition and this geometrical information is utilized in image pre-processing. In pre-processing images are corrected from distortion errors and rectified to plane parallel to tre...

Efficient forest management requires detailed, timely information on forests. The increasing availability and affordability of high spatial resolution remotely sensed imagery provides viable opportunities for developing automatic forest inventories at fine scale. Individual tree crown detection and delineation has become increasingly important for forest management and ecosystem monitoring. Exi...

Crown structure, absorbed photosynthetically active radiation (APAR) and growth were analyzed in 300 replicated loblolly (Pinus taeda L.) and slash pine (Pinus elliottii Engelm. var. elliotti) clones to: (1) quantify genetic variation in crown structural traits, growth and APAR at the species, family and clonal levels; and (2) estimate within-family genetic and environmental influences on measu...

Banana Crown Rot Postharvest Disease Banana is one of the most important tropical crops and is affected by several fungal diseases, such as crown rot postharvest disease [1]. Crown rot is responsible for significant losses in banana fruits [1, 2]. Predominantly, Colletotrichum musae and Fusarium spp. are its causative agents [1, 2]. Inoculum sources include mainly infected flowers but also deca...
