BACKGROUND Electronic methods are increasingly being used to manage health-related data amongst sporting populations. Collection of such data permits analysis of injury and illness trends, improves early detection of injuries and illnesses, collectively referred to as health problems, and provides evidence to inform prevention strategies. The Athlete Management System (AMS) has been employed across a range of sports to monitor health. Australian combat athletes train across the country without dedicated national medical/sports science teams to monitor and advocate for their health. Employing an internet-based system, such as the AMS, may provide an avenue to increase visibility of health problems experienced by combat athletes, and deliver key information to stakeholders detailing where prevention programs may be targeted. OBJECTIVE The objectives of this paper are to: 1) report on the feasibility of utilising the AMS to collect longitudinal injury and illness data of combat sport athletes, and 2) describe the type, location, severity and recurrence of injuries and illnesses that the cohort of athletes experience across a 12-week period. METHODS Twenty-six elite and developing athletes from four Olympic combat sports (boxing, judo, taekwondo and wrestling) were invited to participate in this study. Engagement with the AMS system was measured and collected health problems (injuries/illnesses) were coded using Orchard Sport Injury Classification System (OSICS, version 10.1) and International Classification of Primary Care (version 2). RESULTS Despite over 160 contacts, athlete engagement with online tools was poor with only 13% compliance across the 12 week period. No taekwondo or wrestling athletes were compliant. Despite low overall engagement, a large number of injuries/illness were recorded across the 11 athletes who entered data: 22 unique injuries, 8 unique illnesses, 30 recurrent injuries and two recurrent illnesses. The most frequent injuries were to the knee in boxing (n=41) and thigh in judo (n=9). In this cohort, judo players experienced more severe, but less frequent, injuries than did boxers, yet sustained more illnesses. In 97% of cases, athletes in this cohort continued to train irrespective of their health problems. CONCLUSIONS Amongst athletes who reported injuries, many reported multiple conditions indicating that there is a need for health monitoring in Australian combat sport. A number of factors may have influenced engagement with the AMS, including access to internet, the design of the system, coach views on the system, previous experiences with the system and the existing culture within Australian combat sports. To increase engagement, there may need to be a requirement for sports staff to provide relevant feedback on data entered into the system. Until the barriers are addressed, it is not feasible to implement the system in its current form across a larger cohort of combat athletes.

Electroflocculation is a technique for liquid effluent treatment that has been widely used due to simplicity in operation and to the possibility of application in different types of effluents. This study aimed to evaluate the electroflocculation treatment efficiency, monitoring and controlling an effluent automatically from the textile industry, also considering a feasibility study to photovoltaic generation application. The electrofloculation tests were performed with raw effluent, in a batch reactor containing aluminum electrodes and glass vat. Sensors and a microcontroller make up the electronic system, which monitors and controls voltage, temperature, and time variables and also processes and sends the data to the computer. The tests consist of applying 1 and 2A current in a 3 liters volume taking aliquots in 5, 10, 15 min. The parameters analyzed were: pH, conductivity, turbidity, Chemical Oxygen Demand, and absorbance sweep in 200 to 800 nm range. The samples presented in the visible region a band with the maximum absorbance at 670nm; thus, it was decided to evaluate the system at this wavelength. The results of the electroflocculation tests showed that the best removal of turbidity, COD, and absorbance at 670nm occurred in the conditions of 2A / 10min, with average efficiency above 70%. A photovoltaic system was projected to meeting the demand for the energy electroflocculation system, whose analysis found that the best strategy is connecting the photovoltaic system to the electric power grid. Through financial simulation, It was identified as a significant energy-saving which offsets costs related to system installation. in conclusion, the system developed is efficient in textile effluent treatment and that the photovoltaic system meets the demand for energy from the electroflocculation system, ensuring project sustainability.

There are different methods and devices for the increase of the videosignal information in SEM. For example, with the help of special pure electronic [1] and opto-electronic [2] systems equipotential areas on the specimen surface in SEM were obtained. This report generalizes quantitative universal method for space distribution representation of research specimen parameter by contour equal signal lines. The method is based on principle of comparison of information signal value with the fixed levels.Transformation image system for obtaining equal signal lines maps was developed in two versions:1)In pure electronic system [3] it is necessary to compare signal U (see Fig.1-a), which gives potential distribution on specimen surface along each scanning line with fixed base level signals εifor obtaining quantitative equipotential information on solid state surface. The amplitude analyzer-comparator gives flare sport videopulses at any fixed coordinate and any instant time when initial signal U is equal to one of the base level signals ε.

Bright-field images taken with axial illumination show spurious high contrast patterns which obscure details smaller than 15 ° Hollow-cone illumination (HCI), however, reduces this disturbing granulation by statistical superposition and thus improves the signal-to-noise ratio. In this presentation we report on experiments aimed at selecting the proper amount of tilt and defocus for improvement of the signal-to-noise ratio by means of direct observation of the electron images on a TV monitor.Hollow-cone illumination is implemented in our microscope (single field condenser objective, Cs = .5 mm) by an electronic system which rotates the tilted beam about the optic axis. At low rates of revolution (one turn per second or so) a circular motion of the usual granulation in the image of a carbon support film can be observed on the TV monitor. The size of the granular structures and the radius of their orbits depend on both the conical tilt and defocus.
