Many entanglement distillation schemes use either universal random hashing or breading as their final step to obtain shared almost perfect EPR pairs. Both methods involve random stabilizer quantum error-correcting codes whose syndromes can be measured using simple and efficient quantum circuits. When applied to high fidelity Werner states, the highest yield protocol among those using local Bell...

Cost-effective methods are needed to identify the presence and distribution of tritium near radioactive waste disposal and other contaminated sites. The objectives of this study were to (i) develop a simplified sample preparation method for determining tritium contamination in plants and (ii) determine if plant data could be used as an indicator of soil contamination. The method entailed collec...

The genus Boswellia is one of the 17 genera belonging to Burseraceae family. In this study resin of Boswellia carteri birdwoodcollected or purchased from Tehram herbal Market as a food and non-food for chemical analysis. The essential oils of the resins of Boswellia carteri birdwoodobtained by different methods of distillation (water distillation, steam distillation and hydro-steam distillation...

Process design deals with synthesis and optimization tasks, where process synthesis means to conceive a set of processing units and the interconnections between these units which will fulfill the performance target of the process, and optimization means the evaluation of the best set of parameter values of the system. The intensive use of modular simulators, e.g. ASPEN PLUS or numerical solver ...

The following important question is frequently overlooked: Which variables should we control? The answer is related to finding a simple and robust way of implementing the optimal operating strategy. It is argued that the controlled variables should be those that that give “self-optimizing control”, which is when acceptable operation is achieved with constant setpoints for the controlled variabl...

In the chemical industry the demands regarding process efficiency are permanently increasing. At the same time methods to design indiviual process stages and interconnect them to higly integrated process are reaching their preformance limit. To overcome these limitations the focus of current research has turned to combined processes, i.e. processes that combine the tasks of different process st...

Abstract This paper presents the nonlinear dynamic analysis of an ideal two-reactant-two product reactive distillation. The impact of disturbance magnitudes and directions on openloop stability of the system is studied. An analysis of the physicochemical phenomena present in reactive distillation processes that, under certain operational conditions, causes special types of nonlinear behavior is...

BACKGROUND The Iranian traditional medicine is one of the branches of complementary medicine and it is based on using the dosage forms of plants. One of the most common forms of pharmaceutical plants is Aragh. Due to ease-of-use, distillate is a more acceptable form among the public. In this article, it is attempted to study the usage forms and effects of Aragh according to the valid traditiona...

Non-pinched, minimum energy solutions are important class of distillation designs that offer the potential advantage of a better trade-off between capital investment and operating costs. In this paper, two important tasks associated with non-pinched distillation designs are studied. Thus the novel contributions of this work to the literature are (1) A comprehensive methodology for finding non-p...
