Last years are characterized by increasing penetration of digital information registration methods in various domains of science and technical knowledge. Digital systems are very attractive because of their universality, flexibility, swift action, and simplicity of technical realization, better stability, accuracy, and reproduction quality in comparison with analog methods. Particularly, digita...

OBJECTIVE The goal of this study was to evaluate the utility of the stroke thrombolytic predictive instrument (s-TPI) in predicting clinical outcome in patients with acute ischaemic stroke treated with intravenous tissue plasminogen activator (t-PA). METHODS The study assessed the external validity of the s-TPI in 301 consecutive stroke patients treated with intravenous t-PA. Clinical outcome...

cucumber is one of the main vegetables in iranian food basket. a wide range of pesticides are used for crops protection during the cultivation of vegetables such as cucumber due to heavy pest infestation. analysis of pesticide residues in food and other environmental commodities have become essential requirement for consumers, producers, and food quality control authorities. this study was aime...

Optical fluorescence and absorption are two of the primary techniques used for analytical microfluidics. We provide a thorough yet tractable method for computing the performance of diverse optical micro-analytical systems. Sample sizes range from nano- to many micro-liters and concentrations from nano- to milli-molar. Equations are provided to trace quantitatively the flow of the fundamental en...

Calibration of ground water transport models is often performed using results of field tracer experiments. However, little attention is usually paid to the influence, on resulting breakthrough curves, of injection conditions and well-aquifer interactions, more particularly of the influence of the possible trapping of the tracer in the injection wellbore. Recently, a new mathematical and numeric...
