Positioning mobile systems with high accuracy is a prerequisite for intelligent autonomous behavior, both in industrial environments and field robotics. This paper describes the setup of robotic platform its use evaluation simultaneous localization mapping (SLAM) algorithms. A configuration using robot Husky A200, LiDAR (light detection ranging) sensor was used to implement setup. For verificat...

Efficiency of a sequential ultrafiltration – ion exchange purification system was studied by testing separation of an anionic surfactant (SDBS) from aqueous solutions. Commercially available ultrafiltration membranes with cut-off values of 5, 10, and 30 kDa were used for the tests. The ion exchange processes were carried out on five types of ion-exchange resins – both macroporous and gel-based....

We asked respondents about their attitudes toward restriction of imports, their understanding of the principle of comparative advantage and their attitudes toward globalization and business. Respondents who favored import restrictions scored lower on the test of understanding of comparative advantage, and they had less favorable attitudes toward globalization and toward business. Import restric...

Erythromycin resistance among streptococci is commonly due to target site modification by an rRNA-methylating enzyme, which results in coresistance to macrolide, lincosamide, and streptogramin B antibiotics (MLSB resistance). Genes belonging to the ermAM (ermB) gene class are the only erythromycin resistance methylase (erm) genes in Streptococcus pyogenes with MLSB resistance that have been seq...
