in this paper, polyacrylamide/chromium acetate gel polymer system was prepared as water shut-off system to control water production in one of the iranian oil reservoirs condition. effect of various parameters such as temperature (90 °c) and water formation from view point of salinity and divalent cations, was evaluated on the gelation kinetic and gel strength using bottle testing method. the re...

The use of prolonged respiratory support under the form of high-flow nasal cannula (HFNC) or nasal continuous positive airway pressure (nCPAP) is frequent in newborn infants. Introduction of oral feeding under such nasal respiratory support is, however, highly controversial among neonatologists, due to the fear that it could disrupt sucking, swallowing, and breathing coordination and in turn in...

The method of computational homology is used to analyze natural image 8 × 8 and 9 × 9-patches locally. Our experimental results show that there exist subspaces of the spaces of 8× 8 and 9× 9-patches that are topologically equivalent to a circle and a Klein bottle respectively. These extend the results of the paper ”on the local behavior of spaces of natural images.” To the larger patches. The K...

A 45-year-old prisoner violently inserted a 30 cm bottle into his rectum in the prison. He complained of lower abdominal fullness and inability to pass stool. His vital signs were stable and the abdominal examination did not reveal any peritoneal sign. Multiple longitudinal ulcer like anal fissures were also remarkable in different positions of the anal wall extending to the rectum. Attempts we...

A new, clear-plastic nonvented aerobic FA bottle, designed to prevent breakage, has been developed for the BacT/ALERT blood culture system. We assessed the new plastic FA bottle by comparing its performance with that of the current glass FA bottle for recovery of microorganisms and time to detection of growth in blood samples obtained for culture from adult patients with suspected bloodstream i...
