In the in vivo immature heart, conflicting results are reported for postischemic functional recovery. This study determines whether interpretations of functional recovery are influenced by the contractile performance index (systolic pressure, developed pressure, and maximum rate of systolic pressure increase per unit time) reported or the assessment technique (isovolumetric and variable-volume)...

The recovery of high-quality, valuable end products from cheese whey is a very important industrial process. The aim of this study is to improve the recovered protein content of concentrate stream in cheese whey. The experiments were conducted by using ceramic ultrafiltration (UF) membrane followed by diafiltration (DF) process with a 15kDa molecular weight cut-off (MWCO). The volume concentrat...

Abstract—Though the method of least squares has been used for a long time in solving signal processing problems, in the recent field of sparse recovery from compressed measurements, this method has not been given much attention. In this paper we show that a method in the least squares family, known in the literature as Orthogonal Least Squares (OLS), adapted for compressed recovery problems, ha...

in this research the simulation of an air independent proton exchange membrane fuel cell (pemfc) propulsion system was taken into consideration. the system consists of several parts including pem fuel cell stack, metal hydride and liquid oxygen (lox) tanks, and also pre-heaters of oxygen and hydrogen gases along with other heat exchangers, to ensure proper operation of system. the heat recovery...

The fault recovery of VSC-HVDC transmission system is often influenced by many factors, such as the reactive power compensation characteristics of the inverter and the dynamic performance of DC controllers. In this paper, the PSCAD/ EMTDC simulation tool is used to study the dynamic recovery performance of VSC-HVDC system for several different var compensating devices in VSC-HVDC inverter-Fixed...

OBJECTIVES The aim of this study was to investigate how subjective sleepiness, mood states, simple and high-order cognitive performance change after one night of sleep deprivation (SD) and recover to after 7 h normal recovery sleep opportunity during three recovery days. METHODS Ten healthy subjects participated in this study. We measured their subjective sleepiness, mood states and their per...

Background. Fatigue has an undesirable effect on the continued exercise performance and decreases athlete's activity. Fast lactic acid disposed is high of importance for athletes. Objectives. Therefore, the present article determines the effects of the different frequencies of whole-body vibration after a strenuous activity on blood lactic acid. Methods. 60 athletes were chosen from sel...

software fault-tolerance, process replication failure masking, continuous availability, topology The ambition of fault-tolerant systems is to provide application transparent fault-tolerance at the same performance as a non-fault-tolerant system. Somersault is a library for developing distributed fault-tolerant software systems that comes close to achieving both goals. We describe Somersault and...

Local recovery approaches for reliable mw!ticmt have the potential to provide significant performance gains in terms of reduced bandwidth and delay, and higher system throughput. In this paper we ezamine two local recovery approaches — one server-based, and the other receiver–based, and compare their performance. The server-based approach makes use of specially designated hosts, called repair s...
