a general robotic mechanism was presented for in-pipe inspection oflevel pipes with varied diameter or curved pipelines. the robot employed three legs comprised of parallelogram linkages mechanism which enables adapting to various elbow joints in the piping systems. the curvatures in pipeline are the most important constraints in front of the robot through navigation process. to study the adapt...

The dynamics of the seagrass-sulfide interaction were examined in relation to diel changes in sediment pore water sulfide concentrations in Thalassia testudinum beds and adjacent bare areas in Corpus Christi Bay and lower Laguna Madre, Texas, USA, during July 1996. Pore water sulfide concentrations in seagrass beds were significantly higher than in adjacent bare areas and showed strong diurnal ...

OBJECTIVES To determine the prevalence of incomplete ossification of the humeral condyle (IOHC) and other osseous abnormalities of the elbow in English Springer Spaniels with no history of lameness. METHODS Prospective observational study of English Springer Spaniels with no recent history of lameness. Computed tomography scans of both elbows were obtained from dogs older than six months of a...

Methods a. Bare skin acquisition. b. Cutaneous benchmark: the first sacral piece (S1), the anterior superior iliac spine (ASIS). c. First acquisition in standard position, feet spread natural, hands at shoulder height into vertical bars, elbows drooping. d. Second acquisition in the same position but with feet in a board position with heels spaced 19cm apart [3]. e. A single operator. f. Measur...

Ten patients with 13 ankylosed elbows after burns are described. Six elbows, fixed in nearly full extension, had almost total functional disability; the other seven had varying amounts of deformity. In five of the 13 elbows there was a continuous bony mass with loss of the joint space; these were treated by a modified excision arthroplasty which restored good movement and useful function, thoug...

A physically based, variably saturated flow model was developed to predict soil water dynamics, evapotranspiration (ET) from the vadose zone, and recharge to (or exfiltration from) the saturated zone using mean daily atmospheric forcings and to identify the value of diurnal climate forcings on those predictions. The vadose zone flow is modelled using the Galerkin finite element technique to sol...
