Fine-grained sediments are Quaternary with grain sizes of not more than 2 mm. They start first when meeting water, their stability is related to the initial water volume triggering debris flow, and thus plays an important role in flow hazards early warning. The permeability coefficient inter-controlled factor fine-grained sediment stability. However, there no hyperspectral model for detecting l...

In Kingdom of Saudi Arabia, there are several areas where expansive soil exists in the form of variable-thicknesses layers in the developed regions. Severe distress to infrastructures can be caused by the development of heave and swelling pressure in this kind of expansive shale. Among the various techniques for expansive soil mitigation, the removal and replacement technique is very popular fo...

To understand the degradation processes of organic matter related to sulfate reduction by Sulfate Reduction Bacteria (SRB) in the tidal flat sediments of Hwang-do and Sogeun-ri, Tae-an Peninsula in Chungnam-do, biogeochemical characteristics were analyzed and highlighted using specific microbial biomarkers. The organic geochemical parameters (TOC, δCorg, C/N ratio, long-chain-n-alkane) indicate...

Citation: Nissen KG (2015) Commentary: Psychosocial screening and assessment in oncology and palliative care settings. Depression and anxiety are common in patients with cancer and psychosocial screening in oncology and palliative care settings is suggested as a means to reduce emotional distress in cancer situations (Grassi et al., 2014). In their study, Grassi and colleagues report the result...

The Sorkheh deposit in northwestern Iran exhibits several readily visible general characteristics of sediment-hosted stratiform copper (SSC) mineralization. It consists of fine-grained disseminated base-metal sulfides within gray sandstones (gray beds, the basal whitish Miocene sandstone and shallow-water) that overlie a thick sequence of red beds (Miocene Upper Red Formation). The host gray be...

The design of geotextile containers for dewatering applications typically requires hydraulic compatibility between the geotextile and the confined fill material. Ideally, a geotextile container must successfully retain the solid phase of the fill material and must not be clogged during the dewatering process. This becomes difficult to achieve when the fill material is fine grained and the pore ...

Knowledge of seabed dynamics in nearshore environments is needed to address problems ranging from to the evolution of coastal geomorphology to the changing nature of seabed acoustical properties. One successful approach, used primarily in fine-grained sedimentary environments, has been the application short-lived particle-reactive radioisotopes to quantify sediment deposition and accumulation r...

introduction more than 90% of drinking water in cities around the world and about 40% of the agricultural water supply from groundwater resources.,thus, groundwater quality consideration issue is inevitable . one of the most important parameter which can show the quality of drinking water is nitrate concentration. nitrate enters the groundwater and surface water through the decomposition of hum...
