Influence of occupations by production gymnastics on indicators of physical development and cardiovascular system of office employees

© 2016, International Journal of Pharmacy and Technology. All rights reserved.The article shows the positive impact of production gymnastics on the functional status and physical development of people involved in mental activity. One of the study objectives is the monitoring of the remote influence of industrial gymnastics on the health and physical development of students. The first survey was conducted prior to the production gymnastics exercises, a repeated survey was performed after one year of exercise. The production gymnastics was held in the form of sports breaks twice a day, first time-before lunch two hours after the work start and the second time-half an hour after the lunch break, as the fatigue occurs sooner in the second half of the day. During the examination, the power of a right and a left hand, the chest circumference on inhalation, exhalation and pause were studied, its tour was calculated, the vital capacity of lungs, arterial pressure, heart rate and cardiovascular system reaction to the dosed load (20 squats) were determined. The comparative analysis of health surveys among the accountants allows to make the following conclusions: 1. The exercises during a work day helps to increase lung capacity and the development of chest mobility. 2. The functionality of the cardiovascular system is increased slightly. 3. The number of complaints on headaches, heart pains, muscles, arms and back are reduced. 4. The motor-coordination abilities are improved

Development of combined technologies and multifunctional equipment for application of polymer powder coatings

© 2016 Research India Publications.New processes and a complex of specialized equipment, which allow applying polymer powder coatings onto the surface of materials of various nature in stationary and non-stationary conditions by using combined methods, were developed. Mathematical model of the processes of heating and melting of particles of powder compositions, which provides a perfect homogeneity of solid surfaces with guaranteed quality, was proposed. Operating and design parameters of technological processes and equipment were optimized

Donor-acceptor recombination emission in hydrogen-terminated nanodiamond: Novel single-photon source for room-temperature quantum photonics

In fluorescence spectra of nanodiamonds (NDs) synthesized at high pressure from adamantane and other organic compounds, very narrow (~1 nm) lines of unknown origin are observed in a wide spectroscopic range from ~500 to 800 nm. Here, we propose and experimentally substantiate the hypothesis that these mysterious lines arise from radiative recombination of donor-acceptor pairs (DAPs). To confirm our hypothesis, we study the fluorescence spectra of undoped and nitrogen-doped NDs of different sizes, before and after thermal oxidation of their surface. The results obtained with a high degree of confidence allowed us to conclude that the DAPs are formed through the interaction of donor-like substitutional nitrogen present in the diamond lattice, and a 2D layer of acceptors resulting from the transfer doping effect on the surface of hydrogen-terminated NDs. A specific behavior of the DAP-induced lines was discovered in the temperature range of 100-10 K: their energy increases and most lines are split into 2 or more components with decreasing temperature. It is shown that the majority of the studied DAP emitters are sources of single photons, with an emission rate of up to >1 million counts/s at room temperature, which significantly surpasses that of nitrogen-vacancy and silicon-vacancy centers under the same detection conditions. Despite an observed temporal instability in the emission, the DAP emitters of H-terminated NDs represent a powerful room-temperature single-photon source for quantum optical technologies

The stromal vascular fraction from fat tissue in the treatment of osteochondral knee defect: Case report

© 2018 Salikhov, Masgutov, Chekunov, Tazetdinova, Masgutova, Teplov, Galimov, Plakseichuk, Yagudin, Pankov and Rizvanov. In this study we applied autologous fat tissue stromal vascular fraction (SVF) cells in combination with microfracturing technique in a 36-year-old man with an osteochondral lesion of the medial femoral condyle 8 months after the injury. Cell material was generated by fat tissue liposuction from the anterior abdominal wall with subsequent extraction of the SVF and injected through a mini-arthrotomy portal with subsequent fibrin sealant fixation. The follow-up period was 2 years. Clinical score improved from 23 to 96 according to IKDC and from 10 to 90 according to EQ-VAS at 24 months follow-up. Magnetic resonance imaging (MRI) before the surgery revealed an osteochondral lesion with development of significant trabecular edema that remained unchanged for 6 months despite conservative treatment. MRI 1 and 2 years after the surgery showed the recovery of the damaged cartilage thickness with somewhat uneven structure and a decrease in the trabecular edema of the femoral condyle. The use of SVF cells with fibrin sealant fixation might be a promising approach in the treatment of osteochondral joint lesions. Further studies are required

Temperature change calculation at welding products

Thermal calculation of the welded seams was conducted, made from heat resisting austenitic steel 10X11H20T2P by argon-arc welding. Schedules of temperature increment are constructed during various time moments on mode parameters existing on technology manufacture and on offered welding conditions. Structure forecasting opportunity and mechanical properties of welded connection various zones is shown: a welded seam, weld lines, zones of thermal influence and basic metal by calculation of temperature field changing in time. Calculation data are received at use of standard methods of calculation and under general formulas. Basic methods of experimental temperature test are considered at welding and computer application in calculations of temperature fields. Recommendations are given at the welding modes choice for prevention of hot cracks formation, namely, welding speed reduction up to 6 km/h is recommended. © IDOSI Publications, 2014

The influence of mineral fillers on mechanical properties of polyvinyl chloride composites

The paper reports the investigation results of tensile stress-strain properties of filled PVC composite during static and low cycle testing. The distinctive features of composite mechanical behavior depending on the content of dispersed mineral fillers which are basically industrial waste are established. It is revealed that small filler additives have a strong influence on the structural behavior that manifest itself as their abnormal change depending on the filler content. The experimental data obtained are explained based on the modern ideas about structural morphological model of base polymer structure. © IDOSI Publications, 2013
