    Notes: Abstract This report analyzes our initial experience with window rectostomy (WR) as a new method of fecal diversion for high anorectal malformations (ARM) in 27 males without a urinary fistula between May 1994 and May 1998; total correction was achieved in two stages. In the first stage, during the neonatal period, the dilated rectum was exteriorized as a WR through the left lower abdomen. In the second, after 3–5 months an abdominoperineal pull-through (APPT) procedure was performed in which the window rectostomy was mobilized and taken down to form a new anus. The results were compared with cases of high ARM with urinary fistula that were managed in three stages, i.e., proximal sigmoid colostomy, APPT, and colostomy closure. All 27 cases showed satisfactory results without any mortality or major pelvic infection. The main advantages of WR are that it provides more functioning bowel length after diversion and avoids a colostomy-closure operation and repeated hospitalizations, thus reducing the total cost of treatment.

    Notes: Abstract The research work presented in this paper deals with the determination of the stress concentration at the root of the fillet of a weldment on a T steel specimen. A finite element model was developed for the specimen. Measurements were carried out using the holographic moiré technique. Strain gages were added to evaluate extrapolation techniques proposed in the literature. Good agreement was found between the finite element results and the optically measured values. The strain gage extrapolation technique yielded very low values.
