substituted naphthofurans and naphthopyrans were constructed at high temperature from allyl or propargyl naphthyl ethers via claisen rearrangement in moderate to good yields. also, substituted (trimethylsilyl)-naphthofurans were synthesized from the corresponding naphtofurans.

Adders and multipliers are two main units of the computer arithmetic processors and play an important role in reversible computations. The binary multiplier consists of two main parts, the partial products generation circuit (PPGC) and the reversible parallel adders (RPA). This paper introduces a novel reversible 4×4 multiplier circuit that is based on an advanced PPGC with Peres gates only. Ag...

Sophisticated commercial products and product assemblies can greatly benefit from novel IT-based approaches to the conditioning of these products and of „product knowledge‟, leading to what we call Smart Products. The paper motivates the need for such novel approaches, introduces important relevant challenges and research domains, and provides an early definition of Smart Products.

In an uncertain and competitive environment, product portfolio management (PPM) becomes more challenging for manufacturers to decide what to make and establish the most beneficial product portfolio. In this paper, a novel approach in PPM is proposed in which the environment uncertainty, competitors’ behavior and customer’s satisfaction are simultaneously considered as the most important criteri...

Most of spices are produced using traditional systems. In unsanitary conditions, spices can contain large numbers of pathogenic microbes such as bacteria, molds and yeasts. Some microorganisms are known as human pathogens, which need disinfection mechanisms that minimize their potential harms to active substances in spices. Use of contaminated spices in foods can significantly decrease the shel...
