abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...
The predictions for cellular traffic in the next few years show an exponential growth for mobile data. New transmission techniques and the application of efficient algorithms are required in order to make the best use of the scarce resources in mobile communications to be able to satisfy this growing demand. Following the evolution of mobile cellular systems, the last releases of UMTS1 were alr...
In this research, zinc-iron ferrite nanoparticles were synthesized by thermal treatment method. The presence of crystalline phases by X-ray diffraction (XRD) was determined by X-ray diffraction (XRD), which confirmed the presence of crystalline phases in all nanoparticles. The particle size and morphology of the nanoparticles were obtained using Field Emission Scanning Electron Microscopy (FESE...
Since thee beginning of the present century retroviruses have been reported as causative factors that produced transmissible tumors in birds. However, in 1980 Poiesz et al, established, for the first time, a link between a retrovirus and leukemia called Human Lymphotropic Virus Type 1 (HTLV1). Over the course of past 27 years the epidemiology of human T lymphotropic Virus type l has matured. ...
Introducción: Muchas publicaciones versan sobre diversos aspectos del SARS-CoV-2. Este artÃculo presenta un trabajo de revisión modos transmisión y diseminación nuevo coronavirus.
While in other parts of the world it is on decline, incidence of HIV infection continues to rise in the former Soviet Union (FSU) countries. The present study was conducted to investigate the patterns and modes of HIV transmission in FSU countries. We performed phylogenetic analysis of publicly available 2705 HIV-1 subtype A pol sequences from thirteen FSU countries: Armenia, Azerbaijan, Belaru...
Syphilis remains widespread worldwide, with increasing rates among men who have sex with men. This paper reviews available evidence regarding syphilis transmission, including data on: sexual transmission (transmission probability per sexual partnership), vertical transmission, transmission via blood products and organ donation, and other rare modes of transmission. In addition, host susceptibil...
