Abstract This study confirmed the fact that a large majority of isolated VSDs (74%) detected in utero will spontaneously close. Spontaneous closure rates were higher in utero than those detected in infants or children. Isolated VSDs detected in utero did not contribute to fetal morbidity and mortality.

Energy Conversion and Management, 2019
The main purpose of this research is to optimize the life cycle cost (LCC) while minimizing the annual irreversibility of the system in three different modes of a vertical ground heat pump (water-to-water) including heating, cooling, and multi-usage. The

Journal of Membrane Science, 2019
There is an unmet market demand for membrane-based humidity control air conditioning systems. This paper hypothesizes that this unmet demand results from the lack of optimized membrane module designs for this application.

Protection of VSD transformers
2017 Petroleum and Chemical Industry Conference Europe (PCIC Europe), 2017Variable Speed Drives (VSD) protect themselves as well as the driven motors. In contrast, the isolation input transformer typically requires its dedicated protection. Unlike distribution and power transformers, the protection of VSD duty transformers need to consider several additional aspects, such as non-sinusoidal current with harmonic content ...

The treatment of postinfarction VSD
1975Rupture of the ventricular septum is a relatively uncommon complication of myocardial infarction; in most autopsy series the incidence is l–2%1,2. The defect is almost always associated with ECG evidence of either anterior or inferior infarction and most commonly occurs in the inferior part of the septum towards the apex3.
