SUMMARY In this research, which was done for one year, we examined the stool of 35 HIV+ patients who had chronic, alternative, and usual drugs resistant diarrhoea, who were referred from infectious and Haemophilia wards of Imam Khomeini Hospital in Tehran. All of the stools were examined by different Bacteriologic, Mycologic, and parasitologic techniques, in order to find the etiology of their...

several studies suggest that invertebrate abundance and richness are disrupted and reset at confluences. thus, junctions contribute disproportionately to the overall aquatic biodiversity of the river. in general terms, authors have reported high abundance and diversity due to the major physical heterogeneity at junctions. however, data are still scarce and uncertainties are plentiful.the impact...

Molecular motors are found throughout the cells of the human body and have many different and important roles. These micromachines move along filament tracks and have the ability to convert chemical energy into mechanical work that powers cellular motility. Different types of motors are characterized by different duty ratios, which is the fraction of time that a motor is attached to its filamen...

The paper covers state of the art and latest development of piezoelectric motors at Kaunas University of Technology (Lithuania), that are related to the R&D of laser scanning and deflecting devices, measuring systems, nano-resolution positioning devices on the plane, various applications including teaching aids for Mechatronics studies and even “intelligent” toys. All presented motors are oneor...

Hyper-positive real, matrix-valued, rational functions are associated with absolute stability (the Lurie problem). Here, quantitative subsets of functions, related through nested inclusions, introduced. Structurally, this family turns out to be matrix-convex and closed under inversion. A state-space characterization these a corresponding Kalman-Yakubovich-Popov Lemma, is given. Technically, the...
