Background and Objective: The reliability and validity of monitors for self-monitoring of blood glucose are debated. We evaluated the analytical performance of Accu-check Active (Boehringer Mannheim, Roche) which is one of the most commonly used monitors in Iran. Material and Methods: We compared the monitor readings with the reference values by percentage of values within...

Background and objectives: All three phases of laboratory testing are equally important for improving total quality management, but the pre-analytical phase is the most error-prone. This study aimed to determine the rate and reasons for blood sample rejection in the pre-analytical phase of laboratory testing in a referral hospital in Ruhengeri, Rwanda. Methods: This study was a cross-sectional...

The distribution static synchronous compensator (D-STATCOM) has the characteristics of non-linearity, multivariable and strong coupling. Based on analysis D-STATCOM mathematical model, in order to improve performance linear active disturbance rejection controller (LADRC), solve coupling problem between d-axis q-axis current dynamic tracking response speed anti-interference ability. A with LADRC...

PURPOSE To determine the sensitivity of the Seoul National University (SNU) computerized color vision test for detecting diabetic macular edema. METHODS From May to September 2003, a total of 73 eyes of 73 patients with diabetes mellitus were examined using the SNU computerized color vision test and optical coherence tomography (OCT). Color deficiency was quantified as the total error score o...

BACKGROUND Glucose meter analytical performance criteria required for safe and effective management of patients on tight glycemic control (TGC) are not currently defined. We used simulation modeling to relate glucose meter performance characteristics to insulin dosing errors during TGC. METHODS We used 29,920 glucose values from patients on TGC at 1 institution to represent the expected distr...

Deficiency and inappropriate distribution of reengage station is one of challenges faced by researchers in hydrology and climate science. In this research, evaluate the applicability of four gridded precipitation data products ERA-Interim, PERSIANN-CDR, PERSIANN-CCS and CRU as a supplement or substitute for ground data in a monthly time scales. This assessment was done by comparison with observ...

this study was motivated by the researchers’ goal to unfold the quality of the english translations of persian tourism industry texts and discover the most frequent error patterns the iranian non-native translators have committed in such texts. thus, the following research questions were addressed: 1) are the english versions of persian tourist guidebooks and multimedia compact discs provided b...

AIM To evaluate the effects of chronic smoking on color vision in young subjects. METHODS This study included 91 smokers and 88 non-smokers (a total of 179 volunteers) without any ophthalmologic and systemical disorders. The subjects were between 18-40 years of age with a best corrected visual acuity (BCVA) of 20/20, normal anterior and posterior segment examinations and normal intraocular pr...

a novel technique is investigated for pid controller adaptation in order to control thetemperature of a liquid-phase reactor tank by using a heat exchanger system. as for nonlinearity,time delay problems and model uncertainties introduced by the heat exchanger, an interval type-2fuzzy system (it2fs) is implemented to enhance and improve the total control performance.moreover, the fuzzy inferenc...

in this study the accuracy of one of the vital signs(boyd temperature) reported by the nursing staff was compared with the reporting of the control group,in order to find the problems and ways to solve them.to do this,117 body temperatures reported from hospitalized patients in pediatrics wards in Kerman university No1 hospital were analused.samples were gathered by clustering method from diffe...
