Objectives One of the economical ways of dental caries prevention is using fluoride containing toothpastes. For fluoride to be effective in toothpastes, significant amount of fluoride need to be in solution form. Global standard of fluoride content of toothpastes is 1500 ppm (part per million).This study aimed to determine fluoride content of some special toothpastes. Methods This research was...

the analysis of flow in water-distribution networks with several pumps by the content model may be turned into a non-convex optimization uncertain problem with multiple solutions. newton-based methods such as gga are not able to capture a global optimum in these situations. on the other hand, evolutionary methods designed to use the population of individuals may find a global solution even for ...

Due to the increase of users the efficient usage of spectrum plays an important role in digital terrestrial television networks. In digital video broadcasting, local and global content are transmitted by single frequency network and multifrequency network respectively. Multifrequency network support transmission of global content and it consumes large spectrum. Similarly local content are well ...

With the primacy of content driving the design of new network architectures as well as the successful CDN business model, it is instructive to reconsider problems of content placement from the context of ISPs. In particular, we focus on a near-term future where architectural support for content has become more explicit, or where ISPs have become more proactive in incorporating content hosting i...

this paper presents a method for generating a digital management map to apply cyanazine pre-emergence herbicide. the main objective was to develop a precision method to generate management maps for the variable rate application of herbicide to reduce the amount of herbicide applied and its adverse impact on the environment. first, local and utm coordinates of a field were determined using total...

in 2000, an evaluation of iranian elementary education revealed that it did not successfully prepare students for the future. the failure was attributed to the teacher centered, content-oriented education system. in 2001, the iranian ministry of education began a pilot project that introduced an alternative curriculum, known as “global education,” with unicef’s participation. global education, ...
