The production of particulate matter and harmful gases from different sources is a problem in the cities. An important role in air pollution is played by industry and road transport. Traffic volume continues to grow and road transport has the greatest impact on the atmosphere in the vicinity of the urban roads. Due to the dominant use of combustion engines, exhaust gases contain large amounts of gaseous pollutants as well as particulate matter. They particularly include a large amount of the finest PM fractions, w...

Last year (2017) was one of the three hottest years on record, with many high-impact events including catastrophic hurricanes and floods, debilitating heat waves and drought. Long-term indicators of climate change continue unabated and arctic sea ice coverage remained below average. Of the hottest years on record, 15 out of 17 have come since 2000. By contrast, more than a century has gone by since the planet had a record cold year (1911). At European level, based on the three different observational records of gl...

There is a fact that where surfaces are in contact with relative movement, there is also wear, with these aspects dealing the Tribology. There are other mechanical parts destroyed during functioning by the fatigue of the materials. Usually these two phenomena are studied separately. But there are mechanical systems where these two actions are joined into a single degradation event, leading to a shorter working time for the parts. The study of the tribo-wear as a simultaneous action with the material fatigue, leads...

The main air pollutants in the urban areas are power stations and transport. As a result of fuel combustion, heavy metals and solid particles with unknown composition enter the atmosphere. Concentrations of heavy metals in the snow can be an indicator of air pollution in urban areas, also giving us indications on the origin of pollution. Heavy metals accumulated in the snow in significant quantities in the cold period. But in the spring, runoff after the melting of snow presents a significant source of pollution i...

Humic substances (humic and fulvic acids) are widespread, being present in soil, water, lake sediments, peat, and different coal. Therefore, there is a great interest for their immense role in terrestrial and aquatic systems, as well as their bio-stimulatory effects on plant growth. Humic substances, through their positive effects on plant nutrition and by increasing the tolerance to abiotic and biotic stress, lead to higher yields and superior quality crops. Their role in agriculture is essential, but humic subst...

Carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) are the most important anthropogenic greenhouse gases and their concentrations are continuously increasing. Some scientists consider that water vapor is more an enhancer than a greenhouse gas by itself, even though its concentration in the atmosphere is much higher than those of the other 3 GHGs listed above. But it is not only the concentration of a GHG that counts, but also its percentage of absorption and reemission of infrared radiation, namely its gl...
