in this project, 4,4?-methylenebis(3-chloro-2,6-diethyl trimellitimidobenzene) as a diacid, was prepared by the reaction of trimellitic anhydride (tma) with 4,4?-methylenebis(3-chloro-2,6-diethylaniline) (mcdea). the novel poly(amide-imide) (pai) was synthesized from the reaction of 4,4?-methylenebis(3-chloro-2,6-diethyl trimellitimidobenzene) as a diacid with mcdea under green condition using ...

Governments provide incentives to promote green building practices in the construction sector. Compared with rigid-regulatory incentives, reward and compensation are voluntary because stakeholders can choose whether uptake them or otherwise. The problem is that an explicit list of forms may decide design construct buildings not available them. This paper employs a narrative review academic prac...

abstract: this paper presents the results of pullout tests on uniaxial geogrid embedded in silica sand under monotonic and cyclic pullout forces. the new testing device as a recently developed automated pullout test device for soil-geogrid strength and deformation behavior investigation is capable of applying load/displacement controlled monotonic/cyclic forces at different rates/frequencies an...

This research paper describes the study of combined effect of Fly Ash (FA) and Rice Husk Ash (RHA) on properties of concrete as partial replacement of Ordinary Portland Cement (OPC). These by-products are having high pozzolanic reactivity. In this research, the composition of mix was used with 10% RHA along with 10, 20 and 30% FA as partial replacement of cement. In this study, the compressive ...

We synthesized four novel benzoxazolic and benzimidazolic derivatives of 6-hydroxycoumarin and their photophysical properties were studied. The products with brilliant yellow color shades declared green fluorescence. The emission peaks of the products appeared 456–474 nm. The important characteristic for fluorescent compounds, the Stokes shift νA-νF, oscillator strength f, and fluorescence quan...

We present a proactive queue-management (PQM) algorithm called GREEN that applies knowledge of the steadystate behavior of TCP connections to intelligently and proactively drop packets, thus preventing congestion from ever occurring and ensuring a higher degree of fairness between flows. This congestion-prevention approach is in contrast to the congestionavoidance approach of traditional active...

Green infrastructure (GI) can help bring people together, engaging individuals from different social groupings that may not normally interact. Green space offers possibilities: increasing social activity, improving community cohesion, developing local attachment and lowering crime levels, particularly in deprived communities (Bell et al., 2008; Weldon et al., 2007). Certain groups in society ar...

Five years ago, “Privacy-enhancing technologies for the Internet” [23] examined the state of the then newly emerging privacy-enhancing technologies. In this survey paper, we look back at the last five years to see what has changed, what has stagnated, what has succeeded, what has failed, and why. We also look at current trends with a view towards the future.

Canning of sausage is one of the methods to extend the shelf life of sausage with lower percentage of additives such as nitrite. This method reduces transport and storgae costs, too. The present stduy was carried out in two stages. The first stage consists of preparing sausages with four different formulations in Isfahan Senobar Factory and producing canned sausage. In the second stage, physico...
