This article is a critical review of some of the methods that have been used for the sampling, analysis, and monitoring of vapor-phase toluene diisocyanate (TDI). Only some of the methods that have received relatively widespread application have been addressed in this article. This review includes a "tutorial style" discussion of basic definitions and basic principles and procedures of quality ...

Assessment of exposure to airborne endotoxins has been studied for several years, especially in occupational environments, but a large number of procedures are used for sampling and analysis. This lack of standardization makes it very difficult to compare results and set internationally accepted threshold limit values (TLVs) or occupational exposure limits (OELs) for endotoxin exposure. This pa...

objectives: the authors of this paper hypothesized that vibration stimulation applied by a vibratory orthosis improves balance in patients with parkinson’s disease (pd). in this study we evaluate this hypothesis. methods & materials: fourteen pd patients (12 male and 2 female) with mean age of 59.9±9.1 (±sd) years were participated in this cross- sectional study. using biodex balance system, th...

Developing countries have embarked on the promotion of “ICT access for all” through subsidized Information and Communication Technologies (ICTs), especially in underserviced areas of such countries. The main aim of the “ICT access for all” is to extend the communication services to the large areas of underserviced regions through subsidized communication services. In some instances, subsidies m...

If uniform coding (Gödelization) of potentially infinite sequences of numbers can be performed in PSPACEF, then PSPACE = EXPTIME 6= EXPSPACE = 2-EXPTIME, and, for all p, we have p−EXPSPACE = p+1-EXPTIME; if it can be performed in LINSPACEF, we also have LINSPACE = DTIME(2); the proof fails, when relativized to oracle-TM’s. A by-product of this research is that PTIMEF is not closed under number-...

OBJECTIVES To calculate the Scapular Balance Angle (SBA) reference values in a healthy population between 18 and 85 years old, and to define abnormality criteria for this sample. MATERIALS AND METHODS A descriptive study was conducted on a total of 300 individuals (mean age: 44.83, range: 18-83; proportion male/female: 1.59), calculating the SBA through manual measurement with a goniometer. A...
