Features in Assessing the Psychosocial Approaches Bassed on the Feedback – Received and Transmitted Emotions

The fairness and efficiency of the learning - teaching process result from the behaviour changes of the designed activity. If the evaluation of the behaviour in a psychomotric way in physical education implies probes and tests where the running timing, number of repetitions the long jump, the evaluation of the psychosocial  approaches can be done through the means of some tests which combine the students motricity with the survey on students, with the aim of finding out the social involvement level of each student. The experimental research emphasises the way the tests are handed, under the influence of motor activities for the 2nd form students, in three different schools in Arges. The former test, following Zlate Mielu model, aims at the assessment of the training/ development/ education level of the personality features through the learning of every individual psychosocial profile. The latter test is illustrative of Zapan Gheorghe method and implies the examining of objective appreciation capacity concerning the right way of performing all the exercises and the student capacity of obeying the rules. Through the means of these two tests the students social behaviour is assessed on the grownd of each students the feedback provided by the emotion received or sent to the students. As a result of this research, we concluded that the psychosocial approaches were included in a prosocial behaviour, each and every student being able to show safety and self - confidence in their own psychomotric prospective, as well as fairness regarding their collegues potential quality.</em

Influence of transport activity on environmental factors in Petroşani Basin

Economic development is closely linked to the mobility needs of communities. The main pillars supporting sustainable development are society, the environment and the economy, and the diagnosis of the current situation, the identification of solutions, the development plans and their implementation lead to sustainable development in terms of transport activity. As the Petroşani Basin has a high degree of urbanization, the negative effects of increased road traffic are particularly pronounced in the central areas of the cities. Of the environmental factors, air is the most obvious and most important factor in human health. Taking into account the national and European Community targets in terms of climate change mitigation, the reduction of air and noise pollution and greenhouse gas emissions is becoming a priority objective. Thus, by limiting the growth of road traffic and the adoption of strategic measures in the Petroşani Basin, a reduction in carbon dioxide emissions, nitrogen oxides and particulate matter levels will also be achieved. According to these trends, achieving a clean public transport system and sustainable (like electrical buses) and having infrastructure for the use of electric bicycles and trotters can do for sure reducing the pollutant emissions

Pulsed Laser Fabrication of TiO₂ Buffer Layers for Dye Sensitized Solar Cells

We report on the fabrication of dye-sensitized solar cells with a TiO2 buffer layer between the transparent conductive oxide substrate and the mesoporous TiO2 film, in order to improve the photovoltaic conversion efficiency of the device. The buffer layer was fabricated by pulsed laser deposition whereas the mesoporous film by the doctor blade method, using TiO2 paste obtained by the sol&#8211;gel technique. The buffer layer was deposited in either oxygen (10 Pa and 50 Pa) or argon (10 Pa and 50 Pa) onto transparent conducting oxide glass kept at room temperature. The cross-section scanning electron microscopy image showed differences in layer morphology and thickness, depending on the deposition conditions. Transmission electron microscopy studies of the TiO2 buffer layers indicated that films consisted of grains with typical diameters of 10 nm to 30 nm. We found that the photovoltaic conversion efficiencies, determined under standard air mass 1.5 global (AM 1.5G) conditions, of the solar cells with a buffer layer are more than two times larger than those of the standard cells. The best performance was reached for buffer layers deposited at 10 Pa O2. We discuss the processes that take place in the device and emphasize the role of the brush-like buffer layer in the performance increase

Thin Film Fabrication by Pulsed Laser Deposition from TiO2 Targets in O2, N2, He, or Ar for Dye-Sensitized Solar Cells

Active semiconductor layers of TiO2 were synthesized via pulsed laser deposition in He, N2, O2, or Ar to manufacture DSSC structures. As-prepared nanostructured TiO2 coatings grown on FTO were photosensitized by the natural absorption of the N719 (Ruthenium 535-bis TBA) dye to fabricate photovoltaic structures. TiO2 photoanode nanostructures with increased adsorption areas of the photosensitizer (a combination with voluminous media) were grown under different deposition conditions. Systematic SEM, AFM, and XRD investigations were carried out to study the morphological and structural characteristics of the TiO2 nanostructures. It was shown that the gas nature acts as a key parameter of the architecture and the overall performance of the deposited films. The best electro-optical performance was reached for photovoltaic structures based on TiO2 coatings grown in He, as was demonstrated by the short-circuit current (Isc) of 5.40 mA, which corresponds to the higher recorded roughness (of 44 &plusmn; 2.9 nm RMS). The higher roughness is thus reflected in a more efficient and deeper penetration of the dye inside the nanostructured TiO2 coatings. The photovoltaic conversion efficiency (&eta;) was 1.18 and 2.32% for the DSSCs when the TiO2 coatings were deposited in O2 and He, respectively. The results point to a direct correlation between the electro-optical performance of the prepared PV cells, the morphology of the TiO2 deposited layers, and the crystallinity features, respectively
