In the present paper, by considering the notion of ideals in $MV$-algebras, we study some kinds of ideals in $MV$-algebras and obtain some results on them. For example, we present definition of ultra ideal in $MV$-algebras, and we get some results on it. In fact, by definition of ultra ideals, we present new conditions to have prime ideals, positive implicative ideals and maximal ideals in $MV$...

with a mean grain size below 100 nm. Fig. 1 shows an image taken in a transmission electron microscope of a high-density nanocrystalline (nc)-Cu sample with a mean grain size of 20 nm. The mechanical behavior of a fully-dense nanocrystalline metal is, compared with its coarse-grain counterpart, characterized by a significantly enhanced yield stress and a limited tensile elongation1,2. A simple ...

Links between people, their land, and culture need to be acknowledged " I ndigenous " has a number of usages that differ from " to be born in a specific place, " which is how the Concise Oxford Dictionary defines it. 1 These usages tend to define indigenous by the experiences shared by a group of people who have inhabited a country for thousands of years, which often contrast with those of othe...
