Study of endotracheal tube cuff pressure and time of measurement among intensive care units patients
Introduction: The pressure in the endotracheal tube cuff must be kept within an optimal range, to make sure tracheal capillaries circulation still stable during positive ventilation. This is essential to avoid oral and gastric stuffing aspiration Objective: The objective of this study was to assess the endotracheal tube cuff pressure and time intervals measurements among intensive care units...
We advance the understanding and measurement of concept time by offering a taxonomy four distinct constructs: duration, frequency, timing, sequence. On basis literature review human resource management allied fields (i.e., organizational behavior, industrial psychology, general management, entrepreneurship, strategic studies), we offer recommendations on how to measure each construct as well il...
industrial organizations are complex systems` where the interactions among the various functions such as sales, distribution, manufacturing, materials, finance, human resources and maintenance have to be man-aged towards a common purpose of delivering the customers satisfaction. however, since most of these or-ganizations have a `functional structure`, each function or department works towards ...
Background: Breast cancer is one of the most prevalent malignancies among women in various countries. HER2 overexpression, which is due to different reasons, occurs in 20-30% of breast cancers. HER2 gene encodes an 185kDa transmembrane glycoprotein with 1255 amino acids. This active product triggers downstream intracellular signaling pathways inducing cell proliferation and cell survival. These...
The method of optimal measurement counting time in Gamma spectrometry for soil samples was studied. Gamma spectrometry was done based on minimum detectable activity using the HPGe- p type with efficiency of 30% and FWHM 1.7keV (for 1.33 MeV 60Co). The samples were IAEA-RG Th-1, IAEA-RGU-1 and IAEA-RGK-1 prepared in bottles. The measurements were done for 12 different counting times from 5 min t...
