Implementation of the Water Framework Directive calls for methodologies and tools to quantify nutrient losses from diffuse sources at a river basin district scale. Here, we examine the possibility of using a statistical model for source apportionment and retention of nutrients in a large transboundary drainage basin (44,000 km2). The model approach uses non-linear regression for simultaneous es...

Sentinel node (SN) biopsy, a procedure based on the identification and histologic examination of the first lymph node on the direct drainage pathway from the tumor, is widely used to stage melanoma and other, non-cutaneous, malignancies, such as breast cancer. The technique was introduced by Morton et al1 in 1992 as a new standard in the surgical treatment of localized melanoma. Several later s...

tectonic processes are major factors controlling landform development in tectonically active areas. in order to evaluate quantitative measurement of tectonic activities in the alamarvdasht basin in the south of iran, six different morphological indices including stream-gradient index (sl), drainage basin asymmetry (af), hypsometric integral (hi), valley floor width-valley height ratio (vf), dra...

Abstract Case Summary Melanoma of the abdominal wall is not uncommon, and sentinel lymph nodes are usually located in lymphatic drainage basins axilla or inguinal region. Less frequently, interval can be found along vessels between primary cancer nearest basin. We present case a 53-year-old female with silicone breast implants who underwent scar excision node biopsy for 1mm Breslow thickness su...

in central part of kopeh dagh there is an array of active right-lateral strike-slip faults that obliquely cut the range and produce offsets of several kilometers in the geomorphology and geological structure. geomorphic indices indicate the presence of differential uplifting in history of this area. tectonic activity of the study area is investigated by a large number of dem derived catchments ...

Intermontane basins in the Trans-Pecos region of westernmost Texas and northern Chihuahua, Mexico, are target areas for disposal of interstate municipal sludge and have been identified as possible disposal sites for low-level radioactive waste. Understanding ground water movement within and between these basins is needed to assess potential contaminant fate and movement. Four associated basin a...

the present study carried out to identify neo tectonic activity of the gorgan river basin in golestan province, in north of eastern alborz range is investigated by four geomorphic indices including the stream– gradient index (sl), drainage basin asymmetry (af), reveres symmetry of topography (t) and mountain front sinuosity (smf). result from the analysis is accumulated and expressed as an in...

The incidence of melanoma is increasing rapidly in the United States. Sentinel lymph node biopsy is an important diagnostic tool in the treatment and staging of melanoma. However, many patients with melanoma will have had lymph node surgery for previous melanoma or breast cancer. We set out to examine alterations in drainage patterns in patients with previous axillary dissection for breast canc...

The technique of lymphatic mapping and sentinel lymph node (SLN) biopsy for melanoma has emerged during the last 2 decades as a minimally invasive approach to evaluate regional lymph node basins in patients with intermediate- and high-risk primary cutaneous melanoma and has changed our approach to the clinically negative lymph node basin in melanoma during the same period. This review focuses o...
