The segmental branches of the renal artery vary in number and origin. The 1998, Terminologia Anatomica homologates two branches of the renal artery (anterior, posterior) and five segmental arteries: four from the anterior branch and one from the posterior one. The purpose of this study is to evaluate the renal artery branching pattern, the number and origin of the segmental arteries, as well as...

At HF through UHF frequencies, wave propagation in a forest environment is mainly attributed to a lateral wave which propagates at the canopy–air interface. Due to the existence of tree trunks, significant multiple scattering also occurs which is the dominant source of field fluctuations. Basically, the current induced in the tree trunks by the source and the lateral wave reradiate and generate...

The effects of a sudden rainfall (40 mm d-1) event on the surface waters covering muddy tidal flats were studied during April 2016 at estuarine Cruces River wetland in south-central Chile (~40ºS). study area included flooded vestigial tree trunks, which is evidence coseismic subsidence associated with 1960 Valdivia earthquake as source environmental variability. flat trunks registered fastest a...

Natural rubber is an important and strategic raw material, used in tires, gloves, insulating products, that mainly obtained by cutting the bark of trees. However, complex contour curve tree trunk hard to fit using a tapping machine. Thus, collection would be useful for development machines. In this study, acquisition system based on laser-ranging technology was proposed collect point cloud data...

Knowledge of sap flow variability in tree trunks is important for up-scaling transpiration from the measuring point to the whole-tree and stand levels. Natural variability in sap flow, both radial and circumferential, was studied in the trunks and branches of mature olive trees (Olea europea L., cv Coratina) by the heat field deformation method using multi-point sensors. Sapwood depth ranged fr...

Remote sensing of forest canopies is dominated by the interaction between tree trunks and ground at lower microwave frequencies and/or when the crown layer is tenuous. An e cient and complete electromagnetic scattering model for tree trunks above a tilted rough ground plane has been performed and enhanced. The individual trunks are modelled as nite-length strati ed cylinders, with an external c...

We present a deep, high spatial resolution (0.35 arcsec FWHM), near-infrared (1–2.5 μm) imaging survey of the Eagle Nebula, M 16, made with the VLT, centred on the famous elephant trunks. We compare these data with the existing HST optical images to search for evidence of ongoing or recent star formation in the trunks, and in particular in the 73 small evaporating gaseous globules (EGGs) on the...

AIMS The definitive cardiac outflow channels have three components: the intrapericardial arterial trunks; the arterial roots with valves; and the ventricular outflow tracts (OFTs). We studied the normal and abnormal development of the most distal of these, the arterial trunks, comparing findings in mice and humans. METHODS AND RESULTS Using lineage tracing and three-dimensional visualization ...

This paper presents a novel approach to measure tree trunks and to model the ground using a 3D laser scanner. The 3D scanner, self-build using two 2D Sick scanners on a rotating base, measures each scan line approximately at 45° angle towards the ground and the trees. Single scan lines are segmented to find ground and tree returns. 3D point clouds from the surrounding forest are recorded while ...
