Evaluation of Silver and Gold Nanoparticles on Polyester Fibers by Fluorescent Polarization Raman Spectra
The results of the validation of identification nanoparticle colloidal silver and gold on the polyester
fibers on the background component of the Raman spectra in the control based on the polarization chara c-teristics. The accuracy of identification of nanoparticles was evaluated by the joint probability of crossing
normal scatter intensity distributions Raman spectrograms as silver nanoparticles and gold nanoparticles
on polyester fibers, depending on the longitudinal and transverse polarization of the laser radiation on the
entire range of wave numbers. Defined generalized parameter values common to distributions over the en-tire range for each wave numbers with the polarization of the laser and across the grain, and generalized
reliability of the control and identification of nanoparticles of silver, gold for assessing the likelihood of the
complete group of events. Set the sensitivity of detection reliability.

THE CAPASITY OF USING OUTDOOR GAMES TO IMPROVE THE PHYSICAL QUALITIES AND FUNCTIONAL CAPABILITIES OF THE BODY
Game has a significant role in the modern world. Since ancient times, athletic games and gaming activities have been used to improve mental and physical activity of a human. Nowadays, the importance of sports games, their functions and role have significantly increased. Outdoor games influence human body in different ways. The article regards outdoor games as one of the most effective means of physical education and the best way to improve physical qualities of children. The study is devoted to the research of the possibility of using outdoor games to develop motor skills and increase the adaptive capacity of children’s body when learning to play tennis. Since the games have proved to be an effective method of teaching, the use of outdoor games makes it possible to provide feedback between the student and the teacher in a playful way, optimizing the learning process and increasing motivation. The study revealed an improvement of physical fitness indicators and adaptivity of children’s body as a result of outdoor games application and the game method, indicating the possibility outdoor games application in order to improve physical qualities and functional capabilities of the body, essential for playing tennis
Molecular and ionic diffusion in ion exchange membranes and biological systems (Cells and proteins) studied by NMR
The results of NMR, and especially pulsed field gradient NMR (PFG NMR) investigations, are summarized. Pulsed field gradient NMR technique makes it possible to investigate directly the partial self-diffusion processes in spatial scales from tenth micron to millimeters. Modern NMR spectrometer diffusive units enable to measure self-diffusion coefficients from 10−13 m2 /s to 10−8 m2 /s in different materials on1 H,2 H,7 Li,13 C,19 F,23 Na,31 P,133 Cs nuclei. PFG NMR became the method of choice for reveals of transport mechanism in polymeric electrolytes for lithium batteries and fuel cells. Second wide field of application this technique is the exchange processes and lateral diffusion in biological cells as well as molecular association of proteins. In this case a permeability, cell size, and associate lifetime could be estimated. The authors have presented the review of their research carried out in Karpov Institute of Physical Chemistry, Moscow, Russia; Institute of Problems of Chemical Physics RAS, Chernogolovka, Russia; Kazan Federal University, Kazan, Russia; Korea University, Seoul, South Korea; Yokohama National University, Yokohama, Japan. The results of water molecule and Li+, Na+, Cs+ cation self-diffusion in Nafion membranes and membranes based on sulfonated polystyrene, water (and water soluble) fullerene derivative permeability in RBC, casein molecule association have being discussed
