The possibility of application of 4-nitrocatechol (4-NC) - tetrazolium salt - organic solventsystems for liquid-liquid extraction-spectrophotometric vanadium (IV and V) speciation wasstudied. Six commercially available tetrazolium salts (2,3,5-triphenyltetrazolium chloride (TTC),3-(2-naphtyl)-2,5-diphenyltetrazolium chloride (Tetrazolium Violet, TV); 3-(4,5-dimethyl-2-thiazol)-2,5-diphenyltetra...

Nanomaterials are a new group that has quickly found wide range of applications in medicine, cosmetology, the food, weapons or automotive industry. They also used as fuel additive. This paper reviews literature and assesses current state knowledge regarding use nanoparticles engine fuels. The results obtained so far presented further research directions this field identified.

The study deals with the possibility of reducing peak power consumption when melting snow/ice on pavements, by including meteorological prediction models. It is shown that if meteorological predictions are reasonably accurate e.g. more than 5 h into the future, the use of expensive fossil/electrical back-up fuel can be reduced in district heating systems based on bio fuel.

Information is often modelled as a set of relevant possibilities, treated as logically possible worlds. However, this has the unintuitive consequence that the logical consequences of an agent’s information cannot be informative for that agent. There are many scenarios in which such consequences are clearly informative for the agent in question. Attempts to weaken the logic underlying each possi...

We report a diabetic patient who developed skin lesions on her left forearm and ulnar nerve involvement following admission to the hospital and putting IV catheter for her treatment. Biopsy samples wee taken from her skin lesions and ulnar nerve and with further evaluation after 2 months, the diagnosis of fungal infection due to zygomycetes and mucur was considered based on the presence o...
