REEVALUATION OF ASCE 7-10 EXTERNAL PRESSURE COEFFICIENTS ON THE COMPONENTS AND CLADDING OF LOW-RISE BUILDINGS USING MODERN WIND TUNNEL TESTING DATA
Wind loads for U.S. building designs are specified in a publication of the American Society of Civil Engineers (ASCE 7). Portions of the current version, ASCE 7-10, rely on wind tunnel tests that date back 30-50 years. In recent decades, advances in computer technology have allowed the simultaneous recording of many more pressure taps than was possible before. This research proposes a step-by-step methodology which determines the external pressure coefficients (GCp) on the components and cladding of low-rise buildings using modern aerodynamic wind tunnel databases. Pressure tap time history data is used to calculate the peak pressure coefficients for a comprehensive sweep of arbitrarily selected grid areas, over all available tested wind directions. By incrementing grid area combinations with their contributing taps, GCp can be plotted versus effective area. External pressure coefficients for the analysis of cladding and components are under predicted by the current ASCE 7-10 specifications
Primary tubercular caecal perforation: a rare clinical entity
<p>Abstract</p> <p>Background</p> <p>Intestinal tuberculosis is a common problem in endemic areas, causing considerable morbidity and mortality. An isolated primary caecal perforation of tubercular origin is exceptionally uncommon.</p> <p>Case presentation</p> <p>We report the case of a 39 year old male who presented with features of perforation peritonitis, which on laparotomy revealed a caecal perforation with a dusky appendix. A standard right hemicolectomy with ileostomy and peritoneal toileting was done. Histopathology revealed multiple transmural caseating granulomas with Langerhans-type giant cells and acid-fast bacilli, consistent with tuberculosis, present only in the caecum.</p> <p>Conclusions</p> <p>We report this extremely rare presentation of primary caecal tuberculosis to sensitize the medical fraternity to its rare occurrence, which will be of paramount importance owing to the increasing incidence of tuberculosis all over the world, especially among the developing countries.</p
Focal segmental glomerulosclerosis, Coats’-like retinopathy, sensorineural deafness and chromosome 4 duplication: a new association
We describe the novel association in a girl of nephrotic syndrome due to focal segmental glomerulosclerosis, bilateral sensorineural deafness, basal ganglia calcification, bilateral retinopathy similar to that seen in Coats’ disease, with de novo duplication of a subtelomeric region of chromosome 4q35. The chromosomal duplication was identified during investigation of a possible association with features of fascio-scapulo-humeral dystrophy (FSHD). This duplication has not previously been reported with FSGS and adds to the expanding number of genetic associations with steroid-resistant nephrotic syndrome

Diseño comparativo entre pavimento rĂgido y flexible con subrasante mejorada adicionado 10% de cenizas de carbĂłn mineral en la carretera Cascajal Izquierdo – Ancash
Esta investigaciĂłn está basada en el diseño comparativo entre pavimentos rĂgidos
y flexibles con subrasante natural y sub rasante adicionado 10% de cenizas de
carbón mineral en la carretera Cascajal Izquierdo – Ancash en relación a costo y
tiempo de ejecuciĂłn, esto debido, a que se verificĂł que Ă©stas aumentan su
capacidad portante del suelo. La metodologĂa de investigaciĂłn corresponde al
diseño no experimental, de nivel descriptivo – comparativo, enfoque cuantitativo,
de tipo aplicada. Para efectuar el diseño estructural de pavimentos se basó en el
Método AASHTO -1993, cumpliendo con los requerimientos básicos del Ministerio
de Transporte y Comunicaciones, además, se realizó cotizaciones para el obtener
el presupuesto de cada tipo de pavimentos, finalmente se cuantificĂł mediante el
cronograma de Gantt el tiempo de ejecuciĂłn. Por ende, esta investigaciĂłn concluyĂł
que, el tipo de pavimento flexible con sub rasante mejorada adicionado 10% de
cenizas de carbón mineral es el tipo de pavimento más viable en la carretera
Cascajal Izquierdo (progresiva 6+000 - 7+000 km), tanto del punto de vista
econĂłmico con un presupuesto total de S/. 646,432.27 como del punto de vista en
tiempo de ejecuciĂłn con 50 dĂas calendarios, el cuál es más factible para su
viabilidad
