abstract background: clearing the endotracheal tube through suctioning should be done to promote oxygenation. depth of suctioning is one of the variables in this regard. in shallow suctioning method, the catheter passes to the tip of the endotracheal tube, and in deep suctioning method, it passes beyond the tip into the trachea or brunches. this study aimed to evaluate the effect of shallow and...

background: methicillin resistant staphylococus aureus (mrsa) is a cause of ‎nosocomial infections at intensive care unit (icu), which imposes a high mortality and ‎morbidity on the health care systems.‎ the objective of this study was to evaluate the role of mrsa in patients with clinically ‎suspected ventilator associated pneumonia (vap) in toxicological icu admitted ‎patients.methods: this c...

conclusions the results illustrated the diversity of antibacterial resistance and virulence gene profiles among different sccmec types of s. aureus. the increased prevalence of methicillin-resistant s. aureus isolates containing different toxin and antibiotic resistance genes is a serious threat for the hospitalized patients in the intensive care units. methods in this cross-sectional study tha...

background in recent decades, multidrug-resistant non-fermenting gram-negative pathogens, particularly acinetobacter baumannii and pseudomonas aeruginosa, have been recognized as a major cause of healthcare-associated and nosocomial infections and outbreaks. conclusions the majority of a. baumannii and p. aeruginosa isolates were found to be resistant to commonly recommended antibiotics. theref...

Unit Selection based speech synthesis systems are currently the best performing, producing natural sounding speech with minimal CPU load. One of the important reasons behind their success is the amount of recordings that are now commonly used in synthesis applications. However, in the case of singing applications, it is quite hard for a database to cover a large phonetic space due to the relati...

Thermal effects on the brain, spinal cord and muscles were studied in electrocoagulation and laser photocoagulation. The experiments were performed on cats and rabbits. The monopolar and bipolar electrodes of the electrosurgical unit were applied to the tissues in comparison with the carbon dioxide laser surgical unit. The experiments were divided into the following two groups: 1) Morphological...

E vidence that stroke units save lives and reduce disability is now accepted. In some countries, including the United Kingdom, these findings have contributed to a government directive for all hospitals dealing with stroke to have had a dedicated stroke unit by April 2004. Despite the welcome strength of such political mandates, a number of crucial factors must be addressed if a real life strok...

This contribution introduces a novel unit of syntactic analysis, which is called the component. The validity and utility of the component unit are established in terms of chunking. When informants organize the words of sentences into groups, they are creating chunks, and these chunks then qualify as components in dependency syntax. By acknowledging the nature of chunking and the component unit,...

A lot of time series analysis in economics and nance is to determine whether a unit root and/or seasonal unit root is present in the data. These tests are usually based on unit root tests orginally developed by Dickey & Fuller(1981). Testing for the presence of a seasonal root has been considered by Dickey, Hasza & Fuller (1984). Li(1991) considered tests for the existence of a seasonal and a r...

Unit selection text-to-speech systems currently produce very natural synthetic sentences by concatenating speech segments from a large database. Recently, increasing demand for designing high quality voices with less data creates need for further optimization of the textual corpus recorded by the speaker. The optimization process of this corpus is traditionally guided by the coverage rate of we...
