Education has always been one of the main concerns of human societies, but in different periods and different communities educational goals have varied. Nowadays, and especially here in Iran, the main goal of education is to prepare children for real life and its problem. More specifically, the goal in mathematics education is help students with solving real life problems using their acquired m...

existence of words and concepts of basic sciences including mathematics, geology, biology, chemistry and physics in the poetry causes many form and conceptual rises and falls for which further investigation and criticism are necessary. science always accompanies with accuracy and science introduction  into poetic and literary  area will also involve it in accuracy and give it more depth. someti...

Although many mathematics-based and heuristic approaches have been recently developed on optimally allocation of TCSCs for lines overloads reduction and buses voltage stability enhancement during fault conditions, the works on the TCSCs efficiency to achieve the abovementioned goals are rare. This idea that TCSCs can surely enhance the system’s security must be comprehensively investigated. In ...

in this paper, a useful classification of all lie subalgebras of a given lie algebraup to an inner automorphism is presented. this method can be regarded as animportant connection between differential geometry and algebra and has many applications in different fields of mathematics. after main results, we have applied this procedure for classifying the lie subalgebras of some examples of lie al...

This paper offers an analysis of the meaning of although set within the framework of Relevance Theory. In line with Iten (1998b), although is seen as encoding procedural information that constrains the inferential processes involved in the derivation of implicatures. However, the current account differs from Iten (1998b) in several points. First, it suggests that utterances of the form Q althou...

One may find out the application‎ ‎of mathematics in the areas of ecology‎, ‎biology‎, ‎environmental‎ ‎sciences etc‎. ‎Mathematics is particulary used in the problem of‎ ‎predator-prey known as lotka-Volterra predator-prey equations.‎ ‎Indeed‎, ‎differential equations is employed very much in many areas‎ ‎of other sciences‎. ‎However‎, ‎most of natural problems involve some‎ ‎unknown functions...

Some birds of prey from the Upper Pliocene of Kansas.---Although many arian fossils from the local faunas of the Rexroad formation (Upper Pliocene), Meade County, Kansas, have now been reported, several species of birds of prey remain. These fossils, which Dr. C. W. Hibbard of The University of Michigan Museum of Paleontology a.nd his field parties collected, come from the Rexroad and Fox Canyo...
