Let A be a Banach algebra and X a Banach A-bimodule, the derivation D : A → X is semi-inner if there are ξ, μ ∈ X such that D(a) = a.ξ − μ.a, (a ∈ A). A is called semi-amenable if every derivation D : A → X∗ is semi-inner. The dual Banach algebra A is Connes semi-amenable (resp. approximately semi-amenable) if, every D ∈ Z1w _ (A,X), for each normal, dual Banach A-bimodule X, is semi -inner (re...

Since the 1990s, Morocco’s agriculture has been characterized by co-existence and transformation of both modern traditional smallholder systems. In Atlas Mountains, effects rural–urban have led to intensified irrigated in some agricultural areas, while others were abandoned. To better understand these effects, this study aimed at (1) analyzing land use cover (LULC) changes, (2) assessing struct...

introduction access to tourism destinations and ranking of them are the main aspects of tourism development planning. although the analysis network process (anp) is based on analysis hierarchy process (ahp) but network structure or feedback is dominated in decision making of the options. this article tries to respond to following questions in order to prove the main goal of the research as sele...

In this paper our focus is to study certain covering properties in topological spaces by using semi-open covers. A part of this article deals with Rothberger-type covering properties. The notions of s-Rothberger, almost s-Rothberger, star s-Rothberger, almost star s-Rothberger, strongly star s-Rothberger spaces are defined and corresponding properties are investigated.

introduction climate has always been one the main factors of designing urban spaces in iran since past centuries. by analyzing urban spaces it can be concluded that different cities have different urban spaces due to climate differences. one of the main reasons of the differences in the type and orientation of urban spaces is the climate as one of the key factors in designing these areas. regar...

soil compaction has become a widespread problem in the world and is one of the factors involved in land degradation and declining crop yields, especially in the arid and semi-arid agriculture. the purpose of this study was to investigate the effects of subsoil compaction on morphological, physiological and agronomic aspects of wheat .the research was carried out in the experimental farms of anb...
