Taking the defects of narrow range particle gradation glazed hollow beads and low mechanical strength silica aerogel into consideration, bead have been mixed for composite aggregate insulation mortar. Some measures, such as gradation, were taken to optimize properties formulation, analyzing kinds factors that influence on mortar thoroughly, properties, thermal fire-resistance properties. Under ...

abstract the objective of this study is to investigate the long run and short run interactions between agricultural trade liberalization and shares of the two sectors of agriculture and services in the total export and import products and services of iran during the years 1961-2008. to figure out interactions, the vector correction model was used. the ratio of the sum of imports and exports to ...

When observing a scene horizontally at a long distance in the near-infrared domain, degradations due to atmospheric turbulence often occur. In our previous work, we presented two hybrid methods to restore videos degraded by such local perturbations. These restoration algorithms take advantages of a space-time Wiener filter and a space-time regularization by the Laplacian operator. Wiener and La...

The study investigates how openness influences information and communication technology (ICT) penetration for improved government quality in sub-Saharan Africa for the period 2000-2012. Openness is measured in terms of trade and financial globalisation whereas ICT is proxied with mobile phone and internet penetration rates. Ten bundled and unbundled governance indicators are used. The empirical...

Paul M. Postal, New York University e-mail: [email protected] Preface It might seem plausible to the non-specialist who thinks about natural language (NL) that a given NL, NLx, permits one to report linguistic performances, both performances of NLx elements and those of NLs distinct from NLx. By ‘reporting linguistic performances’ I refer to nothing more arcane than forming statements like ‘A...

It is never pleasant to be the first discussant on the stage and it becomes particularly unpleasant when one is faced with the task of coming up with some constructive criticism of a good paper. And Steve Dowrick’s paper on openness and growth is, indeed, a very good one. In such a situation one way out is to spend a lot of time summarising the paper and its main results, but even that road is ...

Obsessive-compulsive and sleep disorders are among the most common disorders in general population and therefore aim of present study was to determine role of personality traits in predicting obsessive-compulsive disorder and sleep quality among dormitory students. The participants included 277 university students that were selected randomly. Goldberg big five personality inventory-short form, ...

Knowledge of the structure-property-function relationships of dermal scales of armoured fish could enable pathways to improved bioinspired human body armour, and may provide clues to the evolutionary origins of mineralized tissues. Here, we present a multiscale experimental and computational approach that reveals the materials design principles present within individual ganoid scales from the '...

in present research, 17 centrifuge tests have been conducted to study the effect of various parameters such as the number of piles, the distance between piles, gradation and thickness of the granular layer on the load-settlement behavior of a pile raft system. the results showed the importance of granular layer to reduce the settlement of non-connected pile raft system when the roles of piles a...

one of the most controversial aspects of financial markets is capital market liberalization of course not so liberalization under the rules of governmental severities. based on financial theories there are a number of reasons , that capital flows openness should lead to increases in economic growth. on the other hand most economists believe that the cost of openness outweigh the benefits , such...
