Abstract: This paper presents development results of the method of seismoacoustic activity monitoring based on usage vibrosensitive properties of optical fibers. Analysis of Rayleigh backscattering radiation parameters changes, which take place due to microscopic seismoacoustic impacts on the optical fiber, allows to determine seismoacoustic emission sources positions and to identify their types. Results of using this approach are successful for complex monitoring of railways.

Abstract: An obligate intracellular human pathogen Chlamydia trachomatis is the most common bacterial cause of sexually transmitted diseases in females and males worldwide. The diseases range from urethritis, cervicitic, pelvic inflammatory disease, ectopic pregnancy, infertility to trachoma (eye infection) in newborns from infected mothers. Currently, the standard method for C. trachomatis detection in laboratory is polymerase chain reaction (PCR) of the gene encoded for a major outer membrane protein (ompA) followed by electrophoresis. This process requires several hours (3.5 hrs. PCR and sequencing), handling of carcinogenic ethidiumbromide during gel electrophoresis, and is expensive. Thermocycling machine and electrophoresis apparatus are high-priced. Thus, the current research developed C. trachomatis detection by loop-mediated isothermal amplification (LAMP). LAMP is rapid and uses a single temperature; thereby the reaction requires only a heat block or water bath, and thus can be perform
