banjarmasin is known as a tidal waterfront city and it is called city of a thousand rivers. thecity level was approximately -16 cm below the sea level and almost a swamp-land. the urbanization and the citydevelopment programs have changed the city’s physical and spatial plan from a wetland to a mainland structure. theissues of the city's transformation have changed the city structure from ...

Let $R$ be a commutative Noetherian ring with non-zero identity, $fa$ an ideal of $R$, and $X$ an $R$--module. Here, for fixed integers $s, t$ and a finite $fa$--torsion $R$--module $N$, we first study the membership of $Ext^{s+t}_{R}(N, X)$ and $Ext^{s}_{R}(N, H^{t}_{fa}(X))$ in the Serre subcategories of the category of $R$--modules. Then, we present some conditions which ensure the exi...

The notion of identity-based proxy signature with message recovery feature has been proposed to shorten identity-based proxy signatures and improve their communication overhead since signed messages are not transmitted with these kinds of signatures. There are a few schemes for this notion: Singh and Verma’s scheme and Yoon et al.’s scheme. Unfortunately, Tian et al. by presenting two forgery a...

Standard economic models tend to be more speci…c about pecuniary payo¤s than non-pecuniary payo¤s to education. Based on Akerlof and Kranton (2000), we consider a model of career choice and identity where individuals derive nonpecuniary identity payo¤s. Using factor analysis on a range of attitude questions, we …nd two factors related to identity (career orientation and social orientation), whi...

in this paper, we have dened and studied a generalized form of topological vectorspaces called s-topological vector spaces. s-topological vector spaces are dened by using semi-open sets and semi-continuity in the sense of levine. along with other results, it is provedthat every s-topological vector space is generalized homogeneous space. every open subspaceof an s-topological vector space is ...
