Results of the ultra-long duration balloon flight support system development

Advances in Space Research, 2004
Abstract NASA/Wallops Flight Facility (WFF) developed an Ultra-Long Duration Balloon (ULDB) balloon support system that was flown on a balloon test flight at Fort Sumner, NM in May of 2001. The objectives were to develop a flight support system that would meet the generic requirements of supporting ULDB missions for up to 100 days.

Duration of Heart Failure Influences the Outcomes After Mechanical Circulatory Support

The Journal of Heart and Lung Transplantation, 2015
s S81 97% at 2 years and 88% at 4 years. Postoperative survival was 7.6 years (95% CI 7.1 8.1, maximum 9.2). Five patients were transplanted (mean 4.7 years) and 29 (23%) patients died. Conclusion: We describe the largest series of patients with extended survival on CF LVAD support, with mean survival of 7.6 years. This unique cohort had relatively few

Left ventricular assist device recovery: does duration of mechanical support matter?

Heart Failure Reviews, 2018
Heart failure is a widespread condition in the United States that is predicted to significantly increase in prevalence in the next decade. Many heart failure patients are given a left ventricular assist device (LVAD) while they wait for a heart transplant, while those that are not able to undergo a heart transplant may be given an LVAD permanently ...

Social Support During Labor and Duration of Labor: A Community‐Based Study

Public Health Nursing, 1993
Abstract The effect of a birth companion on duration of labor was examined in a sample of 66 nulliparous women in Michigan. Two‐thirds of the sample were single, 66% received Medicaid, and 88% were white. Using simple linear regression, support during labor explained a significant amount of variance in duration of labor.

Duration of left ventricular assist device support affects transplant survival.

The Journal of heart and lung transplantation : the official publication of the International Society for Heart Transplantation, 1997
Left ventricular assist devices have become an important tool in the successful treatment of heart failure as bridges to transplantation. The optimal duration of device support before heart transplantation is debated. We report the effect of left ventricular device support duration on survival after heart transplantation.All patients bridged to heart ...

Game-based evaluation of personalized support for astronauts in long duration mission. [PDF]

, 2008
Long duration missions set high requirements for personalized astronaut support that takes into account the social, cognitive and affective state of the astronaut. Such support should be tested as thoroughly as possible before deployment into space. The in-orbit influences of the astronaut's state factors are hard to simulate on earth.

Support Vector Regression for Predicting the Enhancement Duration of Software Projects

2017 16th IEEE International Conference on Machine Learning and Applications (ICMLA), 2017
Software engineering (SE) has been defined as the application of a systematic, disciplined, quantifiable approach to the development, operation, and maintenance of software. Enhancement is a type of software maintenance. SE involves software planning (SP), and SP includes prediction.
