Bleeding is a common sequela of periodontal and oral surgery. Generally, bleeding is self-limiting. Special circumstances require additional procedures to reduce or eliminate active hemorrhage. Occasionally hemorrhage can be under control when a patient is dismissed from their surgical appointment and, subsequently, the patient will experience either slow seepage of blood or extravascular clot ...

Based on knowing clearly about the goal and principle of the system development, the paper formulated its basic methods and tools as well as the environment of development, studied the structure and the operation procedure of the system. The system also established the database and the evaluation system of the aging and damage situation of seepage control canal with concrete, and therefore impr...

Abstract Conventional triaxial loading tests with different confining pressures and stress-seepage coupling on sandstone seepage were conducted. A permeability model considering strength strain was established, which better characterized the progressive deformation mechanical behaviour of under coupling. The results showed following. (i) pressure not only affects peak but also axial conventiona...

Carbonate communities: The activity of anaerobic methane oxidizing microbes facilitates precipitation of vast quantities of authigenic carbonate at methane seeps. Here we demonstrate the significant role of carbonate rocks in promoting diversity by providing unique habitat and food resources for macrofaunal assemblages at seeps on the Costa Rica margin (400-1850 m). The attendant fauna is surpr...

The lowlands in northeast Germany are among the driest and at the same time the most densely wooded regions in Germany. Low annual precipitation between 500 and 600 mm and the light sandy soils with their low water storage capacity and high porosity lead to limited water availability. Therefore the hydrological functions of forests play an important role in the fields of regional water budget, ...

Jinan is a famous spring city in China. Construction of underground metro system may block groundwater seepage, inducing the depletion risk of springs. This paper presents an assessment of the risk due to metro line construction to groundwater in Jinan City using Analytic Hierarchy Process (AHP) and Geographic International System (GIS). Based on the characteristics of hydrogeology and engineer...
