OBJECTIVE Inpatient hyperglycemia, hypoglycemia, and glucose variability are associated with increased mortality. The use of an electronic glucose management system (eGMS) to guide intravenous (IV) insulin infusion has been found to significantly improve blood glucose (BG) control. This retrospective observational study evaluated the 7-year (January 2009-December 2015) impact of the EndoTool® e...

The study was conducted between 2020 and 2022 in the experimental field of Maize Research Institute-Knezha. subject is following hybrids: Kn-517 group 500-600 FAO with a density 5500 p/da 6000 p/da; Kn-613 over 600 5200 5700 p/da. cultivated hybrids each variation measured height 10 plants. maize grown under control variant T0 – without fertilization two levels: Т1 N8.5P5.4K6.4 T2 N17P10.8K12.8...

The essential oil yield stability of damask rose (Rosa damascena Mill.) as an important medicinal and aromatic plant in different environments has not been well documented. In order to determine appropriate stability parameters, six statistics were studied for essential oil stability of 35 Rosa damascena landraces in seven locations (Sanandaj, Arak, Kashan, Dezful, Stahban, Ke...

Although most nervous system diseases affect women and men differentially, most behavioral studies using mouse models do not include subjects of both sexes. Many researchers worry that data of female mice may be unreliable due to the estrous cycle. Here, we retrospectively evaluated sex effects on coefficient of variation (CV) in 5,311 mice which had performed the same place navigation protocol...

The within subject variability of forced vital capacity (FVC), forced expiratory volumes in one second (FEV1) and half a second (FEV0.5), peak expiratory flow (PEF), and flow rates at 25-75%, 75-85%, 25%, 50%, and 75% of expired FVC were assessed among 7 year old children from the general population. Within occasion variability in 232 children was lowest for FVC (coefficient of variation (CV) 5...

A study was undertaken to evaluate the efficacy of commercially available antimicrobial discs manufactured by Oxoid, UK, HiMedia Laboratories, Mumbai and Span Diagnostics, Surat. The discs were evaluated for their performance on the basis of percentage of coefficient of variation (%CV) which is a measure of reproducibility, mean zone diameters which is a measure of accuracy and range of zone di...

Objective: Evaluate induced astigmatism in progressive addition lenses into deflectometer measurements. Methods: Eleven progressive addition lenses were included with power away from +1.00D and addition 2.00D. Induced astigmatism was assessed twelve points in the zone intermediate, with six on each side of the progressive corridor in deflectometer.Results: There are significant differences betw...

Temperature sensitivity of soil organic carbon (SOC) mineralization (i.e., Q10) determines how strong the feedback from global warming may be on the atmospheric CO2 concentration; thus, understanding the factors influencing the interannual variation in Q10 is important for accurately estimating local soil carbon cycle. In situ SOC mineralization rate was measured using an automated CO2 flux sys...

The maximum strain experienced by the thinnest segment of a non-uniform fiber governs fiber breakage, yet this maximum strain can not be obtained from a normal single fiber test. Only the average strain of the whole fiber specimen can be obtained from a normal single fiber tensile test. This study has examined the relationship between the average strain, the maximum strain and the degree of fib...

the paper demonstrates the result of changes in the physicochemical and biological properties in soil as a result of the operation of illegal dumping sites. soil was sampled from the research points located on the outskirts of the city of bydgoszcz (poland) from the site not affected by illegal dumping sites (control c), within the dumping sites, having removed the waste layer (w), and 10 m awa...
