BACKGROUND Because treatment modalities for carbon monoxide (CO) poisoning, especially normobaric oxygen and hyperbaric oxygen therapies, have limited effects and hyperbaric oxygen is not available at the scene where treatment is most needed, we conducted a study to determine and compare rates of carboxyhemoglobin (COHb) dissociation achieved in human in vitro blood samples under light radiatio...

Laboratory soil incubations provide controlled conditions to investigate carbon and nutrient dynamics; however, they are not free of artefacts. As carbon and nitrogen cycles are tightly linked, we aimed at investigating whether the incubation-induced accumulation of mineral nitrogen (Nmin) biases soil organic carbon (SOC) mineralisation. For this, we selected two soils representative of the C:N...

programs. 1 General coincidence summing problems and specific coincidence summing problems encountered when measuring these two radionuclides on filter papers were discussed in the last issue? In order to perform accurate measurements of 134CS and 60Co in liquid samples using Marinelli beakers, coincidence summing effects should be investigated. Liquid samples of 134Cs and 60Co were prepared in...

A horizontal electrohydrodynamic (EHD) liquid bridge (also known as a “floating water bridge”) is phenomenon that forms when high voltage DC (kV·cm−1) applied to pure in two separate beakers. The bridge, free-floating connection between the beakers, acts cylindrical lens and refracts light. Using an interferometric set-up with line pattern placed background of light passing through split into h...

The increase of Ae. aegypti resistance to conventional insecticides and growing public concern about the environmental impact has resulted in development alternatives mosquito control. Thus, use essential oils (EOs) combination with larvicides may be a strategy used reduce phenomenon resistance. Controlling larvae for prolonged period is important interrupting transmission vector-borne viruses,...

BACKGROUND In ecotoxicological and environmental studies Lemna spp. are used as test organisms due to their small size, rapid predominantly vegetative reproduction, easy handling and high sensitivity to various chemicals. However, there is not much information available concerning spatial and temporal stability of experimental set-ups used for Lemna bioassays, though this is essential for inter...

The closing sentence of Paul Lauterbur’s seminal article describing magnetic resonance imaging is “ Zeugmatigraphic (imaging) techniques should find many useful applications in studies of the internal structures, states, and compositions of microscopic objects” [1] – an obvious understatement about the impact MRI has had on modern medicine and science. MRI continues to deliver exciting new oppo...
