Hirschsprung's disease (HD) is a common congenital disease of colorectum. Although it was described more than one century ago, the effective treatment was established only half a century later. The initially treatment consisted of preoperative diverting colostomy, followed by definite pull-through and closure of colostomy on later date. A variety of procedures like Swenson, Duhamel, Rehbein and...

A PDAE model of a multicomponent gas pipeline has been formulated and solved using the ode15s solver of Matlab. The model with boundary conditions allows for reactions and di usion. Also, general cubic equations of state for pressure and enthalpy are described. To simplify the implementation at this stage, a non-reactive, non-di usional model with fixed feed composition is considered, and multi...

In this review, we present a comparison of the high-pressure phase behaviour of binary systems constituted of CO2 and ionic liquids of the [Cn(m)mim][Tf2N] type. The comparative study shows that the solubility of CO2 in ionic liquids of the [Cnmim][Tf2N] type generally increases with increasing pressure and decreasing temperature, but some peculiarities have been observed. The solubility of CO2...

The theory is der~ved in several stages ([1], [.4], [9], [10]). Each stage exhibits the minim:11 systems that are compatible with a given list of psychological postulates. Successive stages refine either the dynamical'"equations themselves, or the synthesis of netw:)rk COIU1ections, to satisfy additional postulates. This paper reviews the derivation of stage one, for completeness, and proves tw...

A study of the high-pressure phase equilibria in the ternary system oleic acid/1octanol/supercritical CO2 was performed to obtain information for optimization of enzymatic synthesis of n-octyl oleate. Equilibrium data were measured at temperatures of 308.15, 323.15 and 343.15 K over a pressure range from 1 to 25 MPa. Two different apparatuses: a Variable Volume View Cell and a Batch Stirred Tan...

There is a lack of durable thinking on digital longevity. For this we require cross-domain communication and acceptation of standardized concepts, procedures, document formats and IT-tools. Four kinds of standards are required for preservation of digital documents over an indefinite period of time: standards for the architecture, document format standards for preservation, metadata standards fo...
