introduction: the limited resolution of the imaging system causes partial volume effects (pves). these results in spreading of image counts to the neighboring pixels. this phenomenon is called spill-out effect. this study aimed at quantifying pves using imagej. methods:technetium-99m solution of concentration of 74 kbq/ml was filled into spheres a, b and c of diameters: 26 mm, 20 mm and 16 mm r...

BACKGROUND Chronic airway diseases are often associated with marked mucus production, however, little is known about the regulation of secretory activity by locally released endogenous mediators. AIM This investigation was performed to determine the release of MUC5AC mucin from human bronchial preparations using the purinergic agonists adenosine 5'-triphosphate (ATP) and uridine 5'-triphospha...

A self-consistent theory is derived to describe the BCS–Bose-Einstein-condensate crossover for a strongly interacting Fermi gas with a Feshbach resonance. In the theory the fluctuation of the dressed molecules, consisting of both preformed Cooper pairs and “bare” Feshbach molecules, has been included within a selfconsistent T-matrix approximation, beyond the Nozières and Schmitt-Rink strategy c...

In this paper, a method for attitude determination from vector observation suitable for Micro Aerial Vehicle application is proposed. The attitude determination algorithm is an estimator which uses a measurement equation derived from the linearization of the non-linear function which maps vectors from one coordinate frame to the other. The physical realization of the system uses Earth’s magneti...

Previous researches have shown that the digital image color intensity could reflect the crops N status, but there is little information about the comparision of spectrum reflectance in the visible bands with the digital imagery color intensities. A field experiment was conducted to compare the wheat canopy reflectance at visible bands (400-700 nm) at shooting stage with near ground digital imag...

there are a number of techniques available to estimate saturated-liquid molar or specific volumes or densities of liquids. in this study, a new empirical correlation is presented to calculate volume of saturated liquids as a function of critical volume, reduced temperature and acentric factor. an optimization algorithm is utilized to obtain unknown parameters of this correlation by fitting them...
