A shooting range with adjustable targets and shooting positions

Zaključna naloga obravnava strelišče za kratkocevno ognjeno orožje, ki ima na voljo 6 strelskih mest s tarčami, ki se jim da individualno nastavljati razdaljo do strelskega mesta. Poleg tega naj bo možno tudi spreminjanje položaja samih strelskih mest, ki naj se premikajo naenkrat. Predstavljeno je snovanje in dimenzioniranje njegove konstrukcije in pogonov s pripadajočimi krmilji. Za navedene pogone so izbrani tudi ustrezni elektromotorji. Pri snovanju smo si pomagali s programsko opremo za 3D modeliranje (SolidWorks) in za reševanje enačb (Wolfram Mahtematica).The final thesis deals with a shooting range for short-barreled firearms, which should have 6 shooting sites with individually adjustable targets. In addition, it should also be possible to change the position of the shooting stands themselves, which should move at once. The design and dimensioning of the structure and drives are also presented, including the selection of suitable electric motors and associated controls. We have used software for 3D modeling (SolidWorks) and solving equations (Wolfram Mathematica)

Electrooxidation of polar benzotriazole - The impact of supporting electrolyte

Polar benzotriazoles are heterocyclic compounds widely used in industry, and as such are easily released into the environment. These compounds show harmful and toxic effects on plants and some aquatic organisms, biodegrade quite slowly, and some, depending on the structure, have the ability to bioaccumulate. They can only be partially removed by conventional wastewater treatment, and are therefore found in a variety of waters, as well as solid waste. In this paper, synthetic wastewater containing polar benzotriazole was treated by an electrooxidation process. The efficiency of the treatment was tested depending on various parameters, such as: anode material (mixed metal oxide - MMO and boron-doped diamond - BDD), applied current density (10 and 20 mA/cm2), type of supporting electrolyte (NaCl, Na2CO3, Na2SO4, H2SO4) and treatment time (0.5 - 2.5 h). Obtained results showed the treatment was more effective at higher current density and by using BDD anode. Also, the efficiency of the treatment increases with the prolongation of the electrolysis time. After 2.5 h of treatment, 97.9% of benzotriazole was removed, in the presence of sulfuric acid as supporting electrolyte
