The Yellow River alluvial silt has unique engineering properties and is unstable when encountering moisture. mechanical of subgrade can be impaired by the increase in moisture content due to rainwater infiltration, which a negative effect on traffic safety. To further reveal influence deformation characteristics silt, series monotonic cyclic triaxial tests were conducted with different contents...

A large amount of accurate river cross-section data is indispensable for predicting river stages. However, the measured river cross-section data are usually sparse in the transverse direction at each cross-section as well as in the longitudinal direction along the river channel. This study presents three algorithms to resample the river cross-section data points in both the transverse and longi...

Articular cartilage functions by providing a specialized mechanically competent extracellular matrix to withstand load bearing, thus protecting the underlying bones and allowing their near friction-free articulation in the joints. The resident chondrocytes maintain this function throughout life and do so by retaining a stable phenotype that resists hypertrophy and vascular invasion from the bon...

although the delayed exfoliation of primary teeth among children is a common dental problem, simultaneous presence of primary teeth and corresponding successors is a rare feature in adults. this paper reports an unusual case in which both permanent teeth (molars, premolars, and canines) and primary teeth were present simultaneously. this report describes questions concerning the etiology of ove...

background:the diagnostic accuracy of frozen section as an important source of information in surgical pathology is important not only in the management of surgical patients but also as a measure of quality control in surgical pathology. in this study, we evaluated the diagnostic accuracy of frozen sections over a 6-year period in a teaching hospital in iran. methods: we retrospectively review...

pacemaker infection has multiple risk factors. its presentation is most often similar to infected endocarditis and the diagnosis is made through studying blood cultures. transesophageal echocardiography can confirm the diagnosis. the most common microorganisms are staphylococcus speciesis. as a matter of fact, complete pacemaker removal appears to be the only definite treatment. we presented a ...

Human settlements emerged based on natural factors such as adequate water resources and suitable fertile soil. Other altitude, slope, slope direction, the distance to permanent sources, communication paths are substrates that affect distribution of human settlements, some which have a more influential role in formation survival life. This study aims investigate status Iron Age settlement Atrak ...

OBJECTIVES To examine nonylphenol (NP) and 4-t-octylphenol (OP) concentrations and general water quality indicators along a river in the greater Tokyo area and to specify the distribution and origin of alkylphenols. METHODS Water was sampled from the Edogawa River, a main river in the greater Tokyo area, which is a source of public drinking water; and the Sakagawa River system, a tributary of...

Context In arid and semi-arid river systems, waterholes are often the only refugia for aquatic organisms during no-flow spells. Sediment accumulation in reduces their persistence.Aims To assess this threat, we surveyed depth of, dated, waterhole sediments from Moonie River, a northern tributary of Australia’s largest system, Murray–Darling Basin.Methods Fine-sediment was determined three deepes...
