Both mandibular central incisors had extensive caries. Root canals of both mandibular central ...

We consider optimal control problems for the flow of gas or fresh water in pipe networks as well as drainage or sewer systems in open canals. The equations of motion are taken to be represented by the nonlinear isothermal Euler gas equations, the water hammer equations, or the St. Venant equations for flow. We formulate model hierarchies and derive an abstract model for such network flow proble...

Helisoma duryi is a planorbid snail, which has been suggested as biological control agent against the intermediate hosts of schistosomiasis. This snail species has been present in a sugar estate in northern Tanzania since 1972. In January 1981 a snail survey was done in this area in order to determine the distribution and abundance of H. duryi relative to other freshwater snail species. The dis...

Hormozgan Province is located in the south of Iran bordering the Persian Gulf. In this area, malaria is still considered a major health problem. In the province, eleven species of Anopheles were identified: An. pulcherrimus, An. sergenti, An. apoci, An. multicolor, An. subpictus, An. turkhudi, An. fluviatilis, An. stephensi, An. d'thali, An. superpictus, and An. culicifacies, among which only t...

century ago, making a sad havoc in that flourishing town. Within our recollection, it next appeared in the districts of Burdwan, Hooghly, Nuddea and the 24-Pergunnahs in the latter end of the fifties, devastating most of their prospering towns and villages, many of which were once renowned as sanitariums in Bengal. Later on it spread to Rungpore, Rajshahi, Dinajpur, and other districts. Various...

BACKGROUND/PURPOSE The objectives of this study were to identify the bilateral distolingual (DL) canals / roots of the mandibular first molars and second mesiobuccal (MB2) canals of the maxillary first molars in the same Turkish individuals using cone-beam computed tomography (CBCT). MATERIALS AND METHODS A total of 150 CBCT images including all mandibular and maxillary first molars were retr...
