A house is not primarily a solid building; it is a system of activities. It has to accommodate a broad range of diurnal and nocturnal activities throughout the entire year, and this can best be achieved by means of a flexible spatial configuration. Any changes in the house users and their needs affect the space requirements, but we cannot predict and control these processes. This (case s...

Land use in a city has a unique structure, mostly due to the interactions between its spatial configuration and functions, developing into a patchwork of functional regions of various forms. Land price can be seen as one of the indices reflecting these advancements in spatial structure and land use. Through an analysis of the influences of spatial configuration and land use on the formation of ...

methods retrospective cohort study of blunt trauma patients with rib fractures at a level i trauma center that had both a cxr and a ct chest. the ct finding of ≥ 3 additional fractures in patients with ≤ 3 rib fractures on cxr was considered clinically meaningful. student’s t-test and chi-square analysis were used for comparison. results we identified 499 patients with rib fractures: 93 (18.6%)...

abstract: a continuously variable transmission (cvt) is a transmission which may change step less by way of an infinite variety of effective gear ratios between maximum and minimum values. this contrasts with different mechanical transmissions that solely permit just a few different distinct gear ratios to be selected. continuously variable transmissions (cvts) are mechanical devices that allow...

Managing fractures of distal humerus in patients with rheumatoid arthritis (RA) is technically challenging. Total elbow arthroplasty (TEA) is one of the treatment options for these fractures. While elbow motion is largely regained by TEA, comminuted condyle fragments are often ignored. Although numerous approaches for repair of condylar fragments around TEA are described, any universal fixation...
