Influence of the texture on the efficiency of thermal desorption process of soils contaminated with crude oil
The hereby paper presents the experimental research on the influence of three types of soil texture on the
efficiency of decontamination performed using the technology of thermal desorption. The concentrations of
crude oil of the soil samples, the initial ones as well as those following the depollution process were
determined using the Soxhlet method. The decontamination process with thermal desorption on soil samples
was performed using the electric oven with chamber, and with silicon carbide bars. Experimental researches
were performed on the following types of soils: loamy sand, loam and loamy clay. The main parameters
established for the process of thermal desorption were the temperature 350 °C and the amount of time for
keeping the soil samples in the oven, of 5, 10 and 15 minutes. The results of the experiments indicated that
the type of texture has influenced the efficiency of the thermal desorption, and the highest efficiency was
obtained for the sample of loamy sand, treated for 15 minutes

Investigations concerning the influence of sports trainings carried out in a protected area (Natura 2000 site) on various physiological and biological parameters for athletes
The study propose a comparative analysis of biochemical and physiological parameters and their dynamics in athletes training in two different locations: the campus stadium in the Oradea University and a protected area- Valea RoĆie Natura 2000 site. The research was conducted between 31st of May 2016 â9th of June 2016 on the players of a female volleyball team of Oradeaâs University Sport Club, aged between 18 and 24. We used Polar RC3 heart rate monitor, monitoring: distance travelled in each exercise, duration, calories consumed, heart rate, minimum and maximum altitude. After the effort, biological samples were taken, analysing the following indices: Creatine kinase (CK), Lactate dehydrogenase (LDH) and Sideremia; the data interpretation and the results highlighted that organizing outdoor trainings in sites like Natura 2000 has a favourable influence on the biochemical parameters, had a contribution to "breaking" the routine and being a motivating factor for athletes in their activity
