Previously it was believed that stress influence on microorganisms is only negative, reducing the efficiency of biosynthesis. However, it has been shown now that with the use of controlled stress, it is possible to increase the efficiency of microbial cultivation processes. Among other types of stress, oxidative stress is the most significant. When microorganisms are exposed to oxidative stress agents, breaks can occur in nucleic acid molecules as well as of protein molecules, in addition to this, the blockage of ...

One of the reasons for spontaneous combustion of coal waste dumps is the air intake into the body of a dump. Despite the measures taken to isolate the bases and dump slopes, spontaneous combustion of dumps occur in many countries around the world. That breeds a hypothesis that spontaneous combustion process is facilitated by placement of a dump in the geodynamically active zone of the earth's crust. In geodynamically active zone, due to its high permeability, the interaction of the dumps with environment occurs. P...

In practice, the utilization of biosorption in the wastewater treatment systems at large scale is relatively difficult, mainly because the biosorbents have a short duration of use, and their regeneration is not always easy to achieve. Under these conditions, it is necessary to find other valorization ways of biosorbent loaded with metal ions, and a possible solution is their use as supplements for the remediation of anthropically degraded soil. In this study was examined the possible use of marine algae biomass lo...

Atmospheric aerosol fractional and morphological specifics usually depend on their place of origin, they can be solid, liquid or in mixed form.

Architectural styles had a cyclic pattern throughout the history of humanity, however their recurrence was intentional, educated, having more to do with the taste of a society or a group of individuals than with their basic needs. Vernacular architecture emerged as a response to the needs of people and was a collective product, not the masterpiece of an architect. It emerged from the local building techniques and construction material availability, as well as climatic, economic and socio-politic conditions. Underg...
