In the conduct of case-control studies, it has been a general experience that some cases are identified only after death, and that others cannot be personally interviewed because of extreme morbidity. As a way of dealing with the dilemma of obtaining data on unavailable cases, investigators have sometimes chosen to interview a relative or friend (a proxy respondent) whose responses are based on...

strain induced precipitation in hsla-100 steel was investigated by conducting hotcompression and relaxation tests at temperature range of 850°c to 1100°c and strain rate of 0.001s-1 to 1s-1. the absence of dynamic recrystallization at temperatures below 1000°c was attributedto the influence of dynamic precipitation. the stress relaxation tests showed that strain inducedprecipitation is possible...

in this research, the steady-state flow filed around a 3d body and rotor configuration of the robin helicopter is simulated. the rotor is modeled by an actuator disk. for this purpose, an annular computational domain replaces the rotor and some modeled source terms are added to the momentum equations. this modeling of rotor considerably speed up computational time. the flow field over this heli...

BACKGROUND Advance care planning is a voluntary process whereby individual preferences, values and beliefs are used to aid a person in planning for end-of-life care. Currently, there is no local instrument to assess an individual's awareness and attitude towards advance care planning. This study aimed to develop an Advance Care Planning Questionnaire and to determine its validity and reliabilit...

Along the way, by way of illustration, I evaluate various players and teams with respect to baseadvance average. The evaluation of teams leads to further statistical comparisons. Here, the results are equally decisive in favor of base-advance average. For example, over the period 2000-2004, baseadvance average for-and-against predicts wins just as well as runs for-and-against. This is because, ...

In this paper, we derive principles of optimal cyclical monetary policy in an economy without capital, with a cash-in-advance restriction on household transactions, and monopolistic firms that set prices one period in advance. The only distortionary policy instruments are the nominal interest rate and the money supply. In this environment it is feasible to undo both the cash-in-advance and pric...
