Particle size distribution (PSD) affects properties of particulate materials and is used for denoting their quality and performance. Among many techniques available to measure PSD, many are quite often offline methods and are time consuming. Also methods like sieving involve, handling of the material physically and electromagnetically, which is healthy, if avoided for certain materials. Thus th...

Concept of a multichannel electron spin detector based on optical imaging principles and Mott scattering (iMott) is presented. A multichannel electron image produced by standard angle-resolving (photo) electron analyzer or microscope is re-imaged by an electrostatic lens at an accelerating voltage of 40 keV onto the Au target. Quasi-elastic electrons bearing spin asymmetry of the Mott scatterin...

Distribution of various immunocompetent cells, i.e., IgG-, IgM-, IgA-, IgD-, IgE-, CD4-, and CD8-positive cells in palatine tonsils (tonsils) and pharyngeal tonsils (adenoids) of same patients were investigated immunohistologically by using monoclonal antibodies. The proportion of Ig-positive cells and T cell subsets in both tonsils were quantitatively studied by the image analyzer (CUE-2, Olym...

BACKGROUND Few studies on how to diagnose pulmonary neuroendocrine tumors through morphometric analysis have been reported. In this study, we measured and analyzed the characteristic parameters of pulmonary neuroendocrine tumors using an image analyzer to aid in diagnosis. METHODS Sixteen cases of typical carcinoid tumor, 5 cases of atypical carcinoid tumor, 15 cases of small cell carcinoma, ...

Smartphone is a very useful and compact device that fits in person’s pocket, but at the same time it can be used as a tool for criminal activities. In this day and age, people increasingly rely on smart phones rather than desktop computers or laptops to exchange messages, share videos and audio messages. A smartphone is almost equivalent in its application to a PC, hence there are security risk...

The pearl oyster, “Pinctada radiate”, is a native species of Persian Gulf area, which has always been attractive for its ability of producing pearl. Thus, studying the gonadal maturation of the pearl oyster has been important for nucleus implantation to pearl production. In this study, samples were taken in winter and spring from Lavan and Kish Islands. The classic histological methods were use...
