The drainage pattern of a river network is the arrangement in which a stream erodes the channels of its network of tributaries. It can reflect the geographical characteristics of a river network to a certain extent, because it depends on the topography and geology of the land. Whether in cartography or GIS, hydrography is one of the most important feature classes to generalise in order to produ...

concerns about nitrate pollution in groundwater and downstream systems cause development of surface water management system to reduce losses of agricultural drainage water nitrate in subsurface drainage using subsurface irrigation from existing drainage lines, drainage water during the growing season and out of season is controlled. the overall objective of this study was to evaluate the effect...

OBJECTIVE To investigate the redirection of lymphatic drainage post-lymphadenectomy using non-invasive near-infrared fluorescence (NIRF) imaging, and to subsequently assess impact on metastasis. BACKGROUND Cancer-acquired lymphedema arises from dysfunctional fluid transport after lymphadenectomy performed for staging and to disrupt drainage pathways for regional control of disease. However, l...

Chronic subdural hematoma (CSDH) is a curable entity frequently encountered by neurosurgeons. The present study was conducted to explore expert opinion and common practice in Iran. Besides, a Review of randomized clinical trials in literature was performed. A questionnaire including six questions discussing major aspects of practice on CSDH, with multiple choices was designed. A pilot study was...

OBJECTIVE To evaluate discordancy between clinical predictions and lymphatic drainage patterns of primary cutaneous melanoma as determined by preoperative lymphoscintigraphy and intraoperative lymphatic mapping of sentinel lymph nodes (SLNs). DESIGN Before selective SLN dissection, 226 consecutive patients with melanoma underwent preoperative lymphoscintigraphy. SETTING Teaching hospital te...

Background The pattern of cranial venous drainage in syndromic craniosynostosis is unpredictable and not adequately understood. Collateral channels substitute for stenotic venous sinuses and pose potential risk for surgical intervention. The purpose of this study was to analyze the patterns of venous drainage in patients with syndromic craniosynostosis and their influence on operative planning ...

Abstract In the Wadi Qena region, digital elevation model (DEM), aeromagnetic, and magnetotelluric data are processed examined to outline surface water flow patterns, subsurface structures, demonstrate their effects on groundwater direction, assess aquifer thickness relationship between structures inherited (drainage pattern). Qena’s drainage pattern watershed basins were delineated using satel...
