PURPOSE To compare 2 radiographic assessment methods for congenital talipes equinovarus: strapping the ankle with tapes versus dorsiflexion with a wooden block. METHODS Anteroposterior and lateral radiographs were taken with the ankle strapped by tapes or dorsiflexed by a wooden block. Talocalcaneal and tibiocalcaneal angles were measured and analysed. RESULTS 20 radiographic assessments we...

The efficacy of a photostable formulation of methoprene and two photostable juvenoids, fenoxycarb and pyriproxyfen, and their residual activity in inhibiting the emergence of adult cat fleas, Ctenocephalides felis (Bouché), was studied in topsoil. Nursery pots composed of clay, peat, and plastic, and wooden flats were used to hold soil samples. Treated soil samples were exposed to sunlight duri...

The widely used above-the-knee prosthesis is composed of a quadri­ lateral muscle-contour, wooden thigh socket, a knee mechanism, a wooden shank, a SACH foot, and a suitable pelvic suspension. This type of pros­ thesis has met with considerable success in most patients, but it is expensive and not all geriatric patients can wear it. A so-called temporary limb—a modified long brace with a leathe...

A disentanglement puzzle consists of mechanically interlinked pieces, and the puzzle is solved by disentangling one piece from another set of pieces. A string puzzle consists of strings entangled with one or more wooden pieces. We consider the generalized string puzzle problem whose input is the layout of strings and a wooden board with holes embedded in the 3-dimensional Euclidean space. We pr...

a subject of the investigation is the behavior of concrete and reinforced concrete columns under different loading conditions. the experimental study comprised a great number of tests on hinged - end columns with slenderness ratio within 35 and 155 subjected to both short and long - time loads applied at different eccentricities. the strength of concrete and the steel percentage varied in a wid...

Leaks represent a very important hazard for the buildings and they can affect all sorts of building materials and specially wood due to its hygroscopic properties. Excessive moisture content can affect in a negative way building processes such as the installation of wooden floors or the use of wood as a structural material. Moisture meters can provide prompt and non-destructive determination of...

A novel method was developed for the preparation of highly efficient anion- and cation-exchange microHPLC columns using an on-column polymerization of methacrylates having amine or sulfonic acid functional groups onto monolithic silica capillary columns modified with 3-methacryloxypropyltriethoxysilane as the anchor groups. The chromatographic evaluation of the columns using nucleic acids, nucl...

Original scientific paper RC frame structures with specially shaped columns and RC frame structures with rectangular columns are different types of structures with different column sections. A progressive collapse analysis model of RC frames was proposed using the beam-column element and joint element based on the program OpenSees. Progressive collapse performance of the experimental frame was ...

lateral resistance of railway track is one of the most important parameters in lateral stability. this parameterdepends!on the conditions of different components of ballasted railway track (such as density of ballast layer,sleeper spacing, type of sleeper, etc.). from this perspective, type of sleeper has an important effect on lateralresistance. however in some conditions, in technical and eco...
