the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...
The main idea of this paper is to study the dependence between the probability of default and the recovery rate on credit portfolio and to seek empirically this relationship. We examine the dependence between PD and RR by theoretical approach. For the empirically methodology, we use the bootstrapped quantile regression and the simultaneous quantile regression. These methods allow to determinate...
Kinetic models are the most important tools for the prediction and evaluation of the flotation circuits performance. In order to determine the kinetic order and rate of flotation of a Gilsonite sample, flotation experiments were conducted using the combination of Gasoline-Pine Oil, and one test without any collector and frother. The pulp density was 10% and the experiments were carried out in b...
A modified centrifugal elutriation technique is described for the isolation of large numbers of lymphocytes and monocytes. Elutriation was carried out by lowering the rotor speed at a constant flow rate which was generated by hydrostatic pressure. The flow rate could be kept constant if the separation procedure was performed at high pressure and high systemic resistance. Up to 2.3 X 10(9) monon...
The three traditional failure classes are system, media, and transaction failures. Sometimes, however, modern storage exhibits failures that differ from all of those. In order to capture and describe such cases, single-page failures are introduced as a fourth failure class. This class encompasses all failures to read a data page correctly and with plausible contents despite all correction attem...
Background: Given that COVID-19 continues to spread worldwide, has become a public health priority. This study aimed to investigate the correlation between the social capital and the epidemiological indicators of COVID-19. Methods: This survey is an ecological study, so all studied variables are aggregate variables. To collect the variables in the study, a data set was provided, which includ...
This paper addresses the definition of recovery lines in the context of backward recovery whose aim is to cope with failures in distributed sytems. A general framework that allows for several semantics of recovery lines is introduced. Key notions such as missing messages and orphan messages are precisely defined and their impact on the definition of consistency of recovery lines is carefully an...

Three tests were conducted to assess the effectiveness of three different intensities of exercise both in reducing blood lactic acid (LA) levels and in influencing subjects' heart rate (HR), following a 2000 m race in a rowing boat. In the first and second tests these variables were investigated during a 13 min recovery exercise at 60% and 40% of the preceding maximum rowing speed respectively....
