Chemotherapy of acute myeloblastic leukaemia with DAM regimen

32 patients of denovo-ANLL were treated with Doxorubicin, Ara-C and 6-Mercaptopurine (DAM) regimen. Remission induction was instituted with 1-3 cycles of DAM regimen and maintenance was given by 6-MP continuously with intermittent DA (1,5) regimen. In the remission induction, Doxorubicin 30 mg/m2 for 3 days, Ara-C 150 mg/m2 for 5 days and 6-Mp 100 mg/m2 daily was given. Complete remission (CR) was observed in 60% cases. The probability of 2 years disease-free survival of patients with complete remission is 56.73%.     

Advancements in the behavioral modeling of fuel elements and related structures

An important aspect of the design and analysis of nuclear reactors is the ability to predict the behavior of fuel elements in the adverse environment of a reactor system. By understanding the thermomechanical behavior of the different materials which constitute a nuclear fuel element, analysis and predictions can be made regarding the integrity and reliability of fuel element designs. The SMiRT conference series, through the division on fuel elements and the post-conference seminars on fuel element modeling, provided technical forums for the international participation in the exchange of knowledge concerning the thermomechanical modeling of fuel elements. This paper discusses the technical advances in the behavioral modeling of fuel elements presented at the SMiRT conference series since its inception in 1971. Progress in the areas of material properties and constitutive relationships, modeling methodologies, and integral modeling approaches was reviewed and is summarized in light of their impact on the thermomechanical modeling of nuclear fuel elements.     

Two Statistical Cosite Signal-Prediction Models for Mobile Communication Systems

Two statistical cosite signal-prediction models are developed taking into account the effect of mutual coupling between antennas on a finite conductive earth. Both models predict the expected values of the desired and interfering signals, their standard deviations and correlation coefficients at the input terminals of a communication receiver, when such a receiver is in the near field of a transmitting antenna. Sufficient measured data are not available in the literature for various parameters of these models. The model must, therefore, be kept updated as measured data become available. Model 2 is in a form suitable for practical application. Further work is needed before Model 1 can be actually useful.     

Quantitative and qualitative IR studies of some synthesized aromatic polysulfides

Quantitative and qualitative IR analysis of some synthesized aromatic homo polysulfides and copolysulfides based on 4,4-oxydibenzenethiol (IV), 4,4 -dimercaptodiphenyl sulfide (I) and bis-(4-fluorophenyl) Sulfone (II) in 1-methyl-2-pyrrolidone (NMP) has been done. A satisfactory agreement of experimental results with theory was observed.     

Recent results on the evaluation of the overpressure response of concrete and steel containments

Analytical studies have been performed for the evaluation of the ultimate load capacity of concrete containment structures. In addition, analyses of steel containment models were carried out to validate computer codes for the analysis of steel containment structures. This paper reports on some of the results of these analyses, dealing first with the global ultimate load behavior of typical prestressed and reinforced concrete containment structures. The results of these analyses are described, with particular attention given to identifying local effects and failure mechanisms of concrete containment structures. On the basis of the global analysis results, local effects analyses were carried out which show clear evidence of large strain concentrations in the liner. The utility of the ABAQUS-EPGEN code is also demonstrated for three steel containment small-scale models tested by Sandia National Laboratory. The basic geometry of the models consisted of a thin cylindrical shell with a hemispherical dome. One of the models included ring stiffeners in the cylinder, and the other model included penetrations without ring stiffeners. The results of these calculations are presented without test data comparisons.     

Dirac-fock total energies, ionization energies, and orbital energies for uranium ions U I to U XCII

Listed here are the orbital energies, total energies, and ionization energies for ground-state configurations of uranium ions U I to U XCII. These values have been computed with the relativistic Dirac-Fock code due to Desclaux. The ground-state electronic configuration for each ion is determined by comparing the total energies of neighboring configurations and selecting the one with the minimum value. The ionization energies are obtained by building differences between the total energies of the respective ions with and without the valence electron. The term values of the uranium ions have been assigned through comparison with the term values of ionized atoms with the same configuration and the same number of electrons as given in the tables of Moore. The tables presented here should find application in the calculation of opacities in uranium plasmas.     

A novel method of harmonic assessment generated by three-phaseAC-DC converters under unbalanced supply conditions

A three-phase converter is fully analyzed, and the performance of the converter is evaluated under both balance and unbalanced supply situations. It is observed that the level of imbalance in the supply voltage increases the harmonic content of the input current and decreases the power factor of the converter. This situation worsens toward the lower output region of the converter. The nature of the analysis has been kept very general so that future related work can be incorporated     

The effect of evaporation losses in the analysis of counterflow cooling towers

In Merkel's method for the thermal design of counterflow cooling towers, the variation of the water flow from the tower inlet to outlet (due to evaporation losses) is neglected, which does not lead to a convervative design. In this analysis, the water evaporation losses are included in the energy balance and a new technique for the thermal design of cooling towers is developed. A comparison of the present analysis with the Merkel solution indicates that the error in the Merkel method may reach 12%, depending on the design conditions. The present solution is recommended where more accurate results are needed.
