A bstract I study generalisations of U-duality transformations which do not rely on the existence isometries. start by providing more details a recently proposed generalised map between solutions type IIA supergravity form M 7 × S 3 , with NSNS flux, and 11-dimensional supergravity, in three-sphere is replaced four-dimensional geometry encodes three-algebra structure constants. then show that w...

background: the purpose of this study was to investigate the ratio of electromyography (em g) activities of the vastus medialis obliqus (vmo) and vastus lateralis (vl) within seven angles of knee joint range of motion using isometric contraction in open kinetic chain (ok c) and closed kinetic chain (ckc). methods: the dominant knees of 44 healthy female subjects (mean age: 24.84 with range: 20-...

introduction: according to the importance of the back extensor muscle strength in postmenopausal women, this study aimed to determine the relationship between strength and changes in the thickness of back extensor muscles during isometric contraction in healthy and osteoporotic postmenopausal women. material and methods: 42 volunteer postmenopausal women according to their bone mineral density ...

The accurate description of embryonic cardiovascular function requires the adaption of standard measurement techniques to the small scale of the developing heart. In the mature heart, the analysis of ventricular pressure and volume accurately defines function. Because in vivo measures of volume are not feasible in the embryonic heart, we tested the hypothesis that ventricular pressure-area loop...
