Management of Waste in Rural Areas of Gorj County, Romania

Abstract

On the top of the ecological priority list in Romania, waste management is on the third place following the problems regarding the surface and underground water pollution, as well as that of the atmosphere. The clean-up of the landscape represents an issue largely discussed in Romania. The paper presents the advantages of waste management for the landscape, which includes: waste gathering and transfer, waste selection, waste biological treatment and the storage. Some analyses of the constituent components of the soil are presented, in order to assess the possibility to use the compost obtained from waste household within a composting station in agricultural sector of the district of Gorj. The experimental data demonstrated the possibility of using the compost as a fertilizer on the agricultural fields. By applying good management and treatment practices of the household wastes, one may achieve long-tern economic objectives such as: the improvement of public health as well as the protection of the natural resources by diminishing the soil, water and air contamination.

Influence of gamma-ray irradiation on Faraday effect of Cu-doped germano-silicate optical fiber

“…The measured absorption spectra also represented that the strong absorption bands of the Cu-related defect centers were located centering at VIS and UV region with an extension up to near infrared (NIR) region. In addition to the overall increase of optical absorption, distinct absorption bands peaking at 565 nm, 585 nm were also found to appear after the irradiation, and they are identical to the surface plasmon resonance (SPR) absorption of Cu metal particles in the previous reports [16][17][18]24]. Thus Cu 2+ ions in the optical fiber core were thought to be converted to Cu metal particles by the irradiation as following reduction reaction: Cu 2+ + 2e À = Cu.…”

“…And we have found that the Cu ions are involved in the formation of radiation-induced defect centers in the optical fiber that affect the magneto-optical properties. Moreover, a number of studies have also shown that Cu ions in silicate glasses were reduced to those with lower valences by the thermal treatment, the gamma-ray irradiation, and the ion-exchange techniques, which contributed to the change in magneto-optical properties of the glasses [14][15][16][17][18]. Therefore, we have chosen Cu-doped germano-silicate optical fiber to investigate the influence of gamma-ray irradiation on magneto-optical properties, particularly on Faraday effect.…”

Comparative Study Regarding Atmospheric SO2 Content in Rovinari and Turceni Areas

“…Reducing and control emissions of sulfur oxides from combustion and industrial processes can be achieved by applying several measures such as use of fuel with a low sulfur content, replacement of burning sulfur fuels with other energy sources, removing sulfur from fuels prior to burning and removing sulfur oxides from the flue gases [16,17].…”

The State of Air Pollution with PM2.5 in the City of Targu Jiu

“…Recent data suggest that globally, air pollution is one of the largest environmental health risks being responsible for many diseases [2,[10][11][12][13][14][15].…”
