compared to other methods of vaccine production, (e.g. culture flask and bioreactor system), the roller culture method for producing rabies vaccine is simpler, and the equipment easier to install and maintain, and also in the event of contamination of one roller, the entire batch need not be discarded. this system provides a much larger surface area than the culture flask, and also ensures a mu...

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...

There has been a considerable imbalance between the availability of conventional building materials and their demand in recent past. On other hand, plastic waste is abundantly available disposal Polyethylene Terephthalate Plastics (PET) big challenge, as repeated recycling PET bottles poses potential danger being transformed only small proportion are recycled. In this work an attempt made to ac...

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 prevalence of bottle propping (permitting an infant to drink from a bottle unattended) and the determinants of this practice at 1 week and 4 months of life were studied in a selected sample of urban women in Hermosillo, Mexico. The sample (n = 165) consisted of mothers planning to breast-feed who gave birth to healthy infants at one of two public hospitals. Data were obtained by interviewin...

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...
