“…One of the main elements affecting the quality of the conducted overpressure attack is properly carried out tactical ventilation. Effective removal of flammable, hot, and also toxic fire gases from spaces susceptible to their impact is possible first of all while ensuring a properly selected ratio of ventilation openings [31]. Below is a drawing describing the value of the effectiveness of the ventilation performed, depending on the ratio of the area of the ventilation openings (outflow to inlet) [32].…”

Internal fire carries a real threat to health and life, not only of the injured people inside but also rescuers. This is due to the impact of toxic gases, as well as the possibility of dynamic and at the same time dangerous fire phenomena. Despite the constant progress of knowledge about internal fires and the phenomena governing them, as well as the development of technologies and tactics to fighting them, it is still difficult to locate a fire. Researches carried out over the last years, aimed at improving the effectiveness and quality of firefighting activities in residential areas, have now created the most effective and safe technique known as positive pressure attack. It is based on carrying out extinguishing activities inside a fire-covered room under the cover of air generated by mechanical-positive pressure ventilation. Appropriate execution of this technique is possible only through systematic practical exercises supported by thorough theoretical knowledge in the field of fire development dynamics. Taking into account the latest achievements of specialized research centers in the world, this paper presents and characterizes the most important components of the positive pressure attack aimed at increasing the safety and effectiveness of firefighting operations.

“…On the contrary, swirl sprayers shape the water stream into a water cone which is thrown outside [20][21][22][23][24][25][26]. Depending on the nozzle application, manufacturers concentrate on the macro-and microstructure of the spraying liquid [27][28][29][30][31][32]. The uniformity of the spraying liquid is determined by the mass spray density [33][34][35][36][37][38].…”

This study was undertaken to analyze the influence of nozzle type on a mass spray density. The results indicated that the most uniform droplet distribution and spraying area was observed for the impact nozzle P 54. The highest mass spray density and the lowest spraying were noticed for the spiral nozzle TF 6. The high values of mass spray density for TF 6 nozzle were associated with the high K-factor value and the low spray angle. The results also showed that the construction of spiral nozzles influence the stream structure. The value of average mass spray density was twice as low for CW-50 F nozzle compared to TF 6. Material and MethodsThe experiments were performer on a dedicated set-up, composed of a cubic chamber with a nozzle localized in the middle, upper part (Fig.1).

“…Road transport is a significant branch in the developing industries that with increasing number of vehicles is the main issue for the environmental protection [1][2][3][4][5][6]. However, rising number of cars on roads is associated with higher number of car accidents which demands Fire Department engagement [7][8][9][10].…”

Analysis of sorption of vehicle liquids with sand that appear after car accidents reproduced in laboratory scale

Introduction: Increasing number of vehicles corelates with an increase in car accidents' risk which pose a threat of environment contamination. Therefore, this study was undertaken to analyze the sorption process for two vehicle fluids contacted with sand. Methods and findings: Sorption process was analyzed with the use of dedicated experimental set-up in the laboratory scale. Contact of sand (50cm 3 ) with 100cm 3 of two sorbates (brake fluid-BF and diesel-D) with the following properties: pure BF, pure D, 0.75-BF and 0.25-D, 0.5-BF and 0.5-D, 0.25-BF and 0.75-D were investigated. Finally, non-linear regression for the mathematical description of sorption process was prepared. The results indicated that the higher amount of D in mixture the higher absorption of sorbate by sand. Moreover, the highest sorption was recorded for pure BF and the lowest for the mixture of equal amount of BF and D. Furthermore, analysis of absorbed mixtures volume indicated that for the composition of 0.25-BF and 0.75-D, 29ml of liquid was absorbed. While, for the equal amount of brake fluid and diesel 30ml of liquid was absorbed. Finally, for the composition of 0.75-BF and 0.25-D, 27ml of liquid was absorbed.

Serum Cyclophilin A Correlates with Increased Tissue MMP-9 in Patients with Ulcerative Colitis, but Not with Crohn’s Disease

Abstract: The current study suggests that serum CyPA may be an independent additional marker of IBD, especially of UC. Higher CyPA level may be followed by increased MMP-9 in those patients. However, further studies are necessary to verify the role of CyPA in IBD development.
