The contents of polycyclic aromatic hydrocarbons (PAH) in Frankfurtertype sausages were investigated in depency on hot smoking conditions (glow smoke), type of casing, back fat content and different types of wood chips. For the smoking experiments three different types of smoke densities and ventilator velocities, three types of casings, four different back fat contents (10%, 20%, 30%, and 39%)...

RWTH participated in the System Combination task of the Fifth Workshop on Statistical Machine Translation (WMT 2010). For 7 of the 8 language pairs, we combine 5 to 13 systems into a single consensus translation, using additional n-best reranking techniques in two of these language pairs. Depending on the language pair, improvements versus the best single system are in the range of +0.5 and +1....

The emphasis placed on bonding with the introduction of Acoustic Cement Bond Logs has led to a study of many of the variables influencing this property, as well as methods for improving bond at the casing-cement interface. Special cementing problems concerning gas storage wells and tubingless completion wells have also indicated the need for better pipe-cement bonding. This presentation stresse...

A unit that encloses a motor-compressor and a condenser of refrigerant fluid in a single hermetic casing is presented. After a description of the general advantages of the component compared with the traditional solution, as far as weight, size, cost and very low noise emission are concerned, experimental test results are presented. COP values in different working conditions show that a good en...

The plastic deformation and interface micro annulus of oil-well cement during acid fracturing are key reasons for the failure wellbore seal sustained casing pressure. However, most existing research ignores influence cooling effect fracturing, owing to which, design conditions in theoretical analysis may be inconsistent with those actual wellbore, calculation results biased. In this study, a no...

The photographic collections held by the University of Melbourne are a rich resource for those interested in the history of photography in Victoria. Notable collections include those of the Grainger Museum, the Ian Potter Museum of Art and the University of Melbourne Archives (UMA), all of which contain works by some of Victoria's best-known photographers. 1 Of particular significance, however,...

The effective utilization of micro hydropower sources is often realized through the use pumps as turbines (PAT). efficiency PAT about same that original pump. A further increase in and power output can be achieved by modifying parts interacting with flow, especially impeller adjacent volute casing draft tube. This paper presents a user-friendly calculation model Francis turbine design its appli...
