Separateness Of Persons

AbstractProfessor Walen’s book rejects the familiar argument of “double effect,” namely the doctrine that an action that knowingly causes the death of another person cannot be justified merely by its good consequences but only by its good intentions. Professor Walen offers a rival argument. He proposes that we rethink the killing of non-combatants in war on the basis of a theory of “the mechanics of claims” so that the intentional killing of civilians may be occasionally permissible. Such targeting of civilians may be justified, according to the book’s argument, by the aim of eliminating the threat that these civilians may pose—innocently or not—to other persons. In these circumstances, it will not only be permissible, but it would also be a matter of right to kill civilians, which would be derived from a balancing of “claims.” The argument is impressively made but is ultimately unconvincing. All the decisive questions appear to be matters of a balance of “goodness.” The “mechanics of claims” organizes a structure of welfare values that ultimately work as a proxy for act-utilitarianism. As a result, the argument is open to well-known objections regarding justice and the separateness of persons.

Most arguments of Applied Ethics (e.g.slippery slope argument, argument of double effect) are well analyzed. An exception is the argument 'I do not do this because it is not my duty'. It makes sense to call the argument the 'argument of supererogation' (ASE): Since J. Urmson's essay Saints and Heroes of 1958, those actions are called 'supererogations' which (despite of their moral value) are not supposed to be duties. The argument is widely used not only in Applied Ethics, but also in ordinary moral everyday life. Nevertheless, there is a need of investigation because it has an indecency-problem. The argument is convincing if an actor does not want to risk his life. It seems indecent, however, if an actor refuses a simple favor or a service of friendship with the 'argument of super-erogation', although they both constitute no duties. This paper reconstructs the 'argument of supererogation' as a syllogism. It analyzes its formal structure by benefitting from current Anglo-American literature on supererogation. The overall aim of this paper is to solve the problem of indecency.

Stage Crystallization

During the SIT conference in Dubai 2005 a single strike crystallization scheme model based on the way that Russian beet factory operated when refining raw sugar was proposed and suggested that it would be particularly suitable for medium size refineries up to about 2000 t/d RSO (refined sugar output). Now there is operational a 1700 t/d RSO stand-alone refinery that uses the scheme. It melts up to VHP raw sugar with 1200 IU (ICUMSA units) and runs carbonatation followed by a light dosing of PAC (powdered activated carbon) as necessary then double effect evaporation to produce fine liquor. Target color for the fine liquor is 340 IU. The centrifugal run-off needs to be segregated into the higher purity, lower color (so-called white) and lower purity, higher color (so called ‘green’) run-off. The white run-off (about 75%) is sent to white crystallization. The remaining 25% (green run-off) is sent to a three-stage crystallization recovery but, given the high purity regime without affination, the ‘A’ sugar is melted back to fine liquor having been crystallized and purged as if food quality. The results presented in the paper show that the refinery is operating broadly as predicted, producing a refined sugar to EEC 2 standard.

Natural Death

Double Effect Donation claims it is permissible for a person meeting brain death criteria to donate vital organs, even though such a person may be alive. The reason this act is permissible is that it does not aim at one’s own death but rather at saving the lives of others and because saving the lives of others constitutes a proportionately serious reason for engaging in a behavior in which one foresees one’s death as the outcome. Double Effect Donation, we argue, opens a novel position in debates surrounding brain death and organ donation and does so without compromising the sacredness and fundamental equality of human life. Summary: Recent cases and discussion have raised questions about whether brain death criteria successfully capture natural death. These questions are especially troubling since vital organs are often retrieved from individuals declared dead by brain death criteria. We therefore seem to be left with a choice: either salvage brain death criteria or else abandon current organ donation practices. In this article, we present a different way forward. In particular, we defend a view we call Double Effect Donation, according to which it is permissible for a person meeting brain death criteria to donate vital organs, even though such a person may be alive. Double Effect Donation, we argue, is not merely compatible with but grows out of a view that acknowledges the sacredness and fundamental equality of human life.

Abstract Even though the evaporation is a common process in the food industry, there is scarce information about the convective coefficient evaluation as an important parameter for equipment and process design. A research on evaporation of sugar solution in a double effect was carried out. The experimental results obtained in this equipment, from the heat transfer and concentration processes are presented, a range of 2658–6091 W of heat flow was quantified implying computed values of 1431–3763 W/m2K for the convective coefficients and 1020–1815 W/m2K for the overall coefficient. The quantification of the convective coefficient, the fitting methodology and modeling were developed in order, to obtain the correspondent correlations. Then, from a set of several equations, two general relationships are proposed. Both correlations were applied to experimental and supposed data, finding a difference lower than 30% between the experimental and predicted values of the Nusselt number, that was considered as satisfactory.

Absorption Refrigeration System

This paper presents the design of a solar/gas driving double effect LiBr-H2O absorption system. In order to use solar energy more efficiently, a new kind of solar/gas driving double effect LiBr-H2O absorption system is designed. In this system, the high-pressure generator is driven by conventional energy, natural gas, and solar energy together with water vapor generated in the high-pressure generator, which supplies energy to the low-pressure generator for a double effect absorption system. Simulation results illustrate that this kind of system is feasible and economical. Economic evaluation of several systems is also given in this paper in order to get a clear knowledge of the energy consumption of the system.
