Inspired by the active site structure of monoiron hydrogenase, a series of iron complexes are built using experimentally ready-made acylmethylpyridinol and aliphatic PNP pincer ligands. Density functional theory calculations indicate that the newly designed iron complexes are very promising to catalyze the formation of formic acid from H2 and CO2.

over the past few decades, scientists have paid special attention to studying novel and natural hydrocolloids due to the growing demand for ready meals, public awareness on the importance of natural fibers in daily diets, and their wide range of application, especially in foods, pharmaceuticals and herbal medicine. moreover, natural hydrocolloids are preferred to biotechnologic ones (e.g., gell...

In this paper, we consider scheduling of project networks under minimization of total weighted resource tardiness penalty costs. In this problem, we assume constrained resources are renewable and limited to very costly machines and tools which are also used in other projects and are not accessible in all periods of time of a project. In other words, there is a dictated ready date as well as a d...

’Capture Ready’ is a design concept that will enable fossil fuel plants to be more easily and economically retrofitted with Carbon Capture and Storage (CCS) technologies during their life time. However, Capture Ready is not eligible to be financed by selling carbon credits under the Emissions Trading Scheme (ETS) in EU or the Clean Development Mechanism (CDM) market in non-annex one countries. ...

We present the first delay-fault testing approach for Field Programmable Gate Arrays (FPGAs), applicable for on-line testing as well as for off-line manufacturing and system-level testing. Our approach is based on Built-In Self-Test (BIST), it is comprehensive, and does not require expensive external test equipment (ATE). We have successfully implemented this BIST approach for delay-fault testi...

the present paper aims at clarifying the role of the concept “walåyah” in the philosophy of the unity of being in islamic philosophy (waedat al-wujid). the concept “walåyah” is deeply built into the philosophic system of the islamic theory of being, and moreover the dynamic aspect of this concept has always activated islamic philosophy of existence and stimulated the thought of islamic philosop...
