Dr. Pál László, 2nd Department of Medicine, University Medical School, POBox 12, H-4012 Debrecen (Hungary) bin time test and this might raise some new requirements against the thromboplastin. The reagent dependency of the derived fibrinogen method was investigated on ELECTRA 900C (Medical Laboratory Automation, Pleasantville, N.Y.). This coagu-lometer printed out not only the fibrinogen value o...
Spreadsheets are used to develop application software that is distributed to users. Unfortunately, the users often have the ability to change the programming statements (“source code”) of the spreadsheet application. This causes a host of problems. By critically examining the suitability of spreadsheet computer programming languages for application development, six “application development feat...
To aid the development of spreadsheet debugging tools, a knowledge of end-users natural behaviour within the Excel environment would be advantageous. This paper details the design and application of a novel data acquisition tool, which can be used for the unobtrusive recording of end-users mouse, keyboard and Excel specific actions during the debugging of Excel spreadsheets. A debugging experim...
Action potential (AP) alternans has been well established as a mechanism of arrhythmogenesis and sudden cardiac death. Proper interpretation of AP alternans requires a robust method of alternans quantification. Traditional methods of alternans analysis neglect higher order periodicities that may have greater pro-arrhythmic potential than classical 2:1 alternans. The spectral method of alternans...
oscillating reactions are one of the most interesting topics in chemistry and analytical chemistry. fluctuations in concentrations of one the reacting species (usually a reaction intermediate) create an oscillating chemical reaction. in oscillating systems, the reaction is far from thermodynamic equilibrium. in these systems, at least one autocatalytic step is required. developing an instinctiv...
در این پروژه، ابتدا یک قاعده کلی برای طراحی فرآیند خشک کردن مطرح شد و سپس برای اجرای طراحی از محیط Excel استفاده شده است. یکی از خشک‌کن‌های متداول در صنایع تبدیلی محصولات کشاورزی، خشک‌کن تسمه‌ای است که در پژوهش حاضر، برای خشک کردن هویج به‌عنوان مطالعه موردی استفاده شده است. از طریق نرم‌افزار Excel می‌توان تابع هدف (هزینه سالیانه کل) را بهینه کرده و تأثیر متغیرهای طراحی برروی تابع هدف را مشاهده ...
BACKGROUND Whether the rate of drug elution and polymer absorption affects clinical outcomes of biodegradable polymer-based drug-eluting stents (DES) is unknown. The widely used polylactide polymer-based Excel stent (JW Medical, Weihai, China) elutes sirolimus within 180 days, and the polylactide polymer is completely absorbed within 6 to 9 months. In contrast, the poly-lactide-co-glycolide pol...
OBJECTIVE To investigate acute recoil of bioabsorbable poly-L-lactic acid (PLLA) stent. BACKGROUND As newly developed coronary stent, bioabsorbable PLLA stent still encountered concern of acute stent recoil. METHODS Sixteen minipigs were enrolled in our study. Eight PLLA XINSORB stents (Weite Biotechnology Co., Ltd., China) and eight metallic stents (EXCEL, Jiwei Co., Ltd. China) were impla...
We implemented the widely used CXTFIT code in Excel to provide flexibility and added sensitivity and uncertainty analysis functions to improve transport parameter estimation and to facilitate model discrimination for multi-tracer experiments on structured soils. Analytical solutions for onedimensional equilibrium and nonequilibrium convection dispersion equations were coded as VBA functions so ...
VanLehn argued that an essential feature of many intelligent tutoring systems (ITSs) is that they provide feedback and hints on every step of a multi-step solution.But if step-based feedback and hints alone suffice for strong learning gains, as Anderson et al. conjecture ([1]), then perhaps a lightweight tutoring system that employ only feedback and bottom-out hints would have advantages. This ...
