Unequivocal evidence in favor of the concept that a ventricular diastolic vis a fronte contributes to ventricular filling has been established only in the following conditions: a. When the ventricle contains an abnormnlly small residual volume (rat, dog, turtle) ; b. When the ventricle contains a more nearly normal, residual volume due to ejection against the resistance of a fluid column (dog, ...

Analysis and design algorithms for residual generators for non minimum phase systems are given. It is shown that Rm optimization of residual generators applied directly to systems including non m i n i u m phase zeros can be very conservative. To remove this conservatism in the H, optimization of the residual generators, a factorization of the non minimum phase system into a minimum phase part ...

Airways resistance measured by the interrupter technique (Rint) requires little patient cooperation and has been successfully used in young children, but little studied in infants. The authors aimed to evaluate the measurement of Rint in infants, using a commercially available device (the MicroRint), by comparing it with an established technique to measure respiratory resistance: the single bre...

Analysis and design algorithms for residual generators for non minimum phase systems are given. It is shown that H∞ optimization of residual generators applied directly to systems including non minimum phase zeros can be very conservative. To remove this conservatism in theH∞ optimization of the residual generators, a factorization of the non minimum phase system into a minimum phase part and a...

One of the methods to achieve optimal conditions in increasing oil recovery through injecting polymers is by optimizing parameters that influence success provide information and be considered when determining new schemes for implementation future. Optimization obtain optimum value factor best PV, injection rate, time, pressure, adsorption, residual resistance (RRF), inaccessible pore volume (IP...

The use of pyrethroid insecticides in malaria vector control has increased dramatically in the past decade through the scale up of insecticide treated net distribution programmes and indoor residual spraying campaigns. Inevitably, the major malaria vectors have developed resistance to these insecticides and the resistance alleles are spreading at an exceptionally rapid rate throughout Africa. A...

Muscle wasting is a common complication afflicting maintenance hemodialysis (HD) patients, and it is associated with decreased muscle function, exercise performance, physical function, and quality of life. Meanwhile, numerous epidemiologic studies have consistently shown that greater muscle mass (ascertained by body anthropometry surrogates, body composition tests such as dual x-ray absorptiome...

Resistance is an obstacle to endocrine therapy for breast cancer. We measured levels of hypoxia-inducible factor (HIF)-1α in 52 primary breast cancer patients before and after receiving neoadjuvant endocrine therapy with letrozole for at least 3 months. Pre-treatment levels of HIF-1α were associated with negative clinical outcome. Furthermore, levels of HIF-1α were increased in post-treatment r...
