In current construction, there are still areas that utilize natural materials such as aggregates from rivers construction materials, one of which is in the Dumoga, Bolaang Mongondow, North Sulawesi. The communities this area use river concrete mixture development process. purpose study was to provide information public about material characteristics and quality using coarse fine Ongkak River, D...

The inflow of foreign direct investment shows the economic and political strength a country (Bevan & Estrin, 2004). Resources agglomeration have theoretical empirical relationship (Carlton, 1983; Hansen, 1987; Krugman, 1991; Wheeler Mody, 1992; Friedman et al., Head 1995; Henderson Kuncoro, 1996; Ries, Devereux Griffith, 1998; 1999; Guimaraes 2000). This paper has examined impact aggregate ...

Relational databases are used to store a large quantity of data scattered around the world. However, users face difficulties in accessing such data for lack of a more natural way of specifying queries. Techniques that use natural language words to search different information sources on the Web are now very common, but they cannot be employed to search relational databases. This work proposes a...

An aggregate signature scheme (recently proposed by Boneh, Gentry, Lynn, and Shacham) is a method for combining n signatures from n different signers on n different messages into one signature of unit length. We propose sequential aggregate signatures, in which the set of signers is ordered. The aggregate signature is computed by having each signer, in turn, add his signature to it. We show how...

aggregate stability is an important soil property because it dictates how strongly a soil can resist water erosion. the objectives in this study were: (1) to compare the stability of six soil aggregate size fractions, primarily to determine if aggregate stability varies with aggregate size, and (2) to determine with which aggregate size fraction the stability of most soils would be different fr...

We exploit the 2004 Indian Ocean Tsunami as a natural experiment to investigate how aggregate bank lending changes in response to a large and unexpected shock. Using a dataset comprising aggregate bank loans at provincial level, we assess the impact of the Indian Ocean Tsunami of 2004 on aggregate provincial lending in Thailand. The results of a Difference-in-Differences investigation suggest t...

We present a dynamic analysis of the evolution of preferences in a strategic environment. In our model, each player’s behavior depends upon both the game’s payoffs and his idiosyncratic biases, but only the game’s payoffs determine his evolutionary success. Dynamics run at two speeds at once: while natural selection slowly reshapes the distribution of preferences, players quickly learn to behav...

The present investigation revealed the effect of using silica fume and copper slag as a partial replacement of cement and fine aggregate, respectively on the mechanical properties of the concrete. Due to the depletion of natural sand resource worldwide with the increment of industrial waste, simultaneously, partial replacements of fine aggregate with copper slag have been attempted. Therefore, ...
