Could we define " I " ? Throughout this article we give a negative answer to this question. More exactly, we show that there is no definition for " I " in a certain way. But this negative answer depends on our definition of definability. Here, we try to consider sufficient generalized definition of definability. In the middle of paper a paradox will arise which makes us to modify the way we use...

For a graph property P and a graph G , a subset S of vertices of G is a P -set if the subgraph induced by S has the property P . The domination number with respect to the property P , denoted by γP(G) , is the minimum cardinality of a dominating P -set. Any property P satisfied by all edgeless graphs is called nondegenerate. For any graph G with n vertices and maximum degree ∆(G) , γP(G) ≤ n−∆(...

Since, choline chloride caking causes serious operating difficulties and customer complaints, two experiments were conducted to optimize in vitro production of a novel encapsulated choline chloride (ECC) with minimum hygroscopic property and optimize delivery in gastrointestinal tract (GIT). The in vivo verification test of ECC was used to compare it with the commercial choline chloride (CC) in...
