the quality of pressure distribution over the atmosphere of the sea level and geopotential altitude at different atmosphere layers affect on many climate and meteorology phenomena of the earth surface. one of the important meteorology phenomenon is the occurrence of frost phenomenon especially late spring frost. in this surrey, occurring late spring frost days and minimum temperature during the...
Background: The basic and instrumental activities of daily living are prerequisites for living with a good quality of life. On the contrary, lack of movement and physical inactivity are considered as the main cause of pressure injuries. Accordingly, this study aimed to determine the relationship between the basic and instrumental activities of daily living with the risk of pressure ulcers in pa...
a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...
Background and Aim: Despite of developments in healthcare systems and ongoing investments to prevent pressure ulcers, it still remains as a major problem particularly in critical care units . This study aimed to investigate the relationship between the level of oxygenation and hemodynamic status in the occurrence of pressure ulcer in mechanically ventilated patients. Material& Methods: It w...
In this study, we investigated the preconsolidation pressure (P C) of sedimentary soft rock and its relationship with brittle-ductile transition (BDT) pressure. We proposed a generalized G) suitable for both soil rock, which is defined in terms yield stress initial sediment structure under confined lateral compression. then explored digenetic effect on P G using 24 types. Next, BDT were verifie...
