Dams and the water systems they support must be monitored, maintained, repaired when necessary so can continue to provide benefits communities serve. This study presents methods results from a robotic crawler-based ground penetrating radar (GPR) inspection of rehabilitated concrete hydroelectric dam spillway located in Alabama, USA. spillway, which was recently inspected repaired, showed eviden...

Large wood increases the morphological and hydraulic complexity of rivers, yet it may block modify flood discharge capacity structures. To assess related risk, blockage probability estimation for structures such as reservoir spillways is needed. This work presents unstudied parameters large with a reservoir-type approach flow, where inflow velocity has negligible magnitude. Experiments were con...

Ecological traps can be caused when partial restoration leads organisms to make maladaptive habitat choices. One example of this is fishways (e.g., fish ladders) that provide upstream passage at dams but are not paired with adequate downstream passage. We tested the hypothesis attracting anadromous fishes spawn above a dam, blocking their offspring an ecological trap. Using passive integrated t...

conclusions due to the shorter :union: time, to some extent less complication rate and comparable functional and clinical results, the authors recommend to use the mipo technique in treating the mid-distal humeral shaft fracture. results the median of :union: time was shorter in the mipo group (4 months versus 5 months). the time of surgery and functional outcomes based on the ucla and meps sco...

Anterior dislocation of the shoulder joint with ipsilateral humerus shaft fracture is a very rare injury. Until July 2006 only 18 cases have been reported in the literature. Here we report a case of Anterior Shoulder dislocation with greater tuberosity and shaft of humerus fracture. The patient was treated by Open reduction and internal fixation of the shaft fracture followed by closed reductio...

BACKGROUND There are many ways to treat aseptic non-union of femoral shaft fractures with reported varied success rate. Amongst all these, Exchange nailing is the simplest and most successful technique for treating aseptic non union of femoral shaft fractures. We have carried out a prospective study in the Department of Trauma & Orthopaedics, Ayub Medical College Abbottabad to analyse the role ...

The adult peripheral nervous system of Drosophila includes a complex array of mechanosensory organs (bristles) that cover much of the body surface of the fly. The four cells (shaft, socket, sheath, and neuron) which compose each of these organs adopt distinct fates as a result of cell-cell signaling via the Notch (N) pathway. However, the specific mechanisms by which these cells execute their c...

BACKGROUND To study phacoemulsification probe shaft/wound and corneal surface/tip temperatures in vivo during longitudinal, torsional and combined phacoemulsification modes and their relationship to machine parameters. DESIGN This was a prospective study at Chaithanya Eye Hospital and Research Institute, Trivandrum, India (tertiary). PARTICIPANTS Twenty-two eyes of 22 patients were randomiz...
