the composition of the essential oils of teucrium chamaedrys l. belongs to the family lamiaceae, it is growing wild in the margin of mountainous roads of arid and cold climate of north iran. in this research, essential oils of t. chamaedrys, extracted and measured at the different location by different methods of distillationand then were analyzed by gc and gc/ms. investigation and comparison o...

We present the results of UMBC’s participation in the Web and Novelty tracks. We explored various heuristics-based link analysis approaches to the Topic Distillation task. For the novelty task we tried several methods for exploiting semantic information of sentences based on the SVD technique. We used SVD to expand the query and to filter redundant sentences. We also used a clustering algorithm...

The objective of the study is to assess the external and internal exposures to aromatic hydrocarbons in the tar and oil naphthalene distillation processes at a coke plant. 69 workers engaged as operators in tar and oil naphthalene distillation processes and 25 non-exposed subjects were examined. Personal analyses of the benzene, toluene, xylene isomers, ethylbenzene, naphthalene, indan, indene ...

We present our work on constructing multi-scale deep convolutional neural networks for automatic speech recognition. Several VGG nets have been trained that differ solely in the kernel size of the convolutional layers. The general idea is that receptive fields of varying sizes match structures of different scales, thus supporting more robust recognition when combined appropriately. We construct...

Medicinal plante Borazambol with the scientific name of Perovskia abrotanoides Karel. belongs to the family Lamiaceae. It is growing wild in the margin of mountainous roads of arid and cold climate of north Iran. It is for a long time that indigenous people by different methods in traditional medicine use its products in preventing and curing diseases. In this research, essential oils of Perovs...

Distillation (Hinton et al., 2015) and privileged information (Vapnik & Izmailov, 2015) are two techniques that enable machines to learn from other machines. This paper unifies the two into generalized distillation, a framework to learn from multiple machines and data representations. We provide theoretical and causal insight about the inner workings of generalized distillation, extend it to un...

Coboiling distillation is a special method of separating the azeotropic system mixture, which widely used in petroleum refining and chemical production. This paper reviewed selection characteristics azeoliling agents, introduced research progress home abroad detail. The compares advantages disadvantages traditional constant boiling new heat pump, compare advantages, presents prospect distillati...

Reactive distillation processes couple chemical reactions and physical separations into a single unit operation. The ethyl acetate production by esterification reaction is equilibrium limited and is suitable to be carried out in a distillation column. In the present work, a reactive distillation column for the production of ethyl acetate is simulated using Aspen Plus. The component compositions...

Vapour recompression system has been used to enhance reduction in energy consumption and improvement in energy effectiveness of distillation columns. However, the effects of certain parameters have not been taken into consideration. One of such parameters is the column heat loss which has either been assumed to be a certain percent of reboiler heat transfer or negligible. The purpose of this st...

Air gap membrane distillation (AGMD) experiments were performed with varied temperature and varied module inclination angles to characterize the effect of module angle on permeate production and thermal performance. While AGMD is potentially one of the most energy efficient membrane distillation configurations, transport resistances in the air gap typically dominate the thermal performance, res...
