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...

I tested 80 male and 80 female subjects between the ages of 3 and 7 years on two exercises of isometric trunk flexor muscle strength (half-hold hooklying position and supine flexion position) and one exercise of isotonic trunk flexor muscle strength (hooklying sit-ups) to establish normative data for trunk flexor musculature capabilities. Measurements included the length of time the half-hold h...

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 ...

present study describes the length-weight (lwr) and length-length (llr) relationships of a freshwater catfish eutropiichthyes vacha hamilton from indus river, sindh, pakistan. a total of 281 specimen of e. vacha were collected from fisherman?s catch from february 2005 to january 2006, are used for this study. the parameters a and b of the length-weight relationship were calculated as w= alb are...
