Performance organizzativa e carichi di lavoro nello studio sui Consorzi Regionali di Bonifica

2022

The objective of our research was to verify, through an empirical survey, the measuring of the relationship between workload and performance within complex public organizations. Starting from the reference literature the research approach adopted was of a mixed type characterized by an exploratory design and the analysis of a case study. #e data collection was carried out through documentary sources and some structured interviews administered to the management and the various sector heads of reclamation consortium studied. Based on the interviews carried out, a relationship between the measurement of the workload and the performance within the institution examined is inferred, because there…

Soil chemical and biochemical properties of a salt-marsh alluvial Spanish area after long-term reclamation

2009

Marisma, one of the largest salt-marsh alluvial areas in SW Spain, has been reclaimed since 1970 by artificial drainage and amendment with phosphogypsum (PG) so as to reduce Na+ saturation. Within the reclaimed area, two 250- × 20-m plots were treated as follows: (1) amendment with 25 Mg/ha of PG every 2 to 3 years between 1979 and 2003 (plot PY); (2) like PY but PG treatment stopped after 1997 (plot DR). A contiguous virgin Marisma salt-marsh plot (MV), neither drained nor amended, was the control. In MV, soil microbial biomass C, most enzyme activities and total organic C content were much greater than in PY and DR soils, despite the salinity stress. The decrease in soil organic matter co…

Chlorohydrocarbons, PCB congeners, polychlorodioxins, furans and dibenzothiophenes in pine needles in the vicinity of a metal reclamation plant

1995

Abstract Chlorohydrocarbons, PCB congeners, polychlorodioxins, furans and dibenzothiophenes in pine needles in the vicinity of a metal reclamation plant were analyzed by GC/ECD and GC/MS. Wax and the rest of the needles were analyzed separately. As a rule the concentrations of α-HCH (0.5–13.6 ng/g), γ-HCH (0.4–7.3 ng/g), HCB (0.2–3.4 ng/g), PCB congeners (0.2–67 ng/g), PCDDs and PCDFs were higher in the older needles. The ratio of the concentration in the wax to the concentration in the rest of the needles was higher in the younger needles. The concentrations of PCB congeners, TeCDDs and TeCDFs were higher in the needles collected in the area nearest to the plant. The samples, obviously, co…

Methodologies for feasibility studies related to wastewater reclamation and reuse projects

2006

Abstract About 20% of the total surface water in Europe is strongly threatened due to pollution problems, and 60% of European cities over-exploit their groundwater resources. The European Framework Water Directive established that by the year 2015 “a good ecological state” of all European water resources and a sustainable use of water must be achieved. Wastewater reuse presents a promising solution to the growing pressure on Europe's water resources. However, wastewater reuse implementation in Europe faces obstacles that include insufficient public acceptance; technical, economic and hygienic risks; and lack of regulations. On the other hand, a very important aspect to implement a water reu…

Fruit Trees and Bushes as a Biodiversity Element in the “Górażdże” Quarry Reclaimed Areas

2019

The assumption of biological land reclamation in the forest direction is to introduce trees and shrubs on the reclaimed area so as to bring it as close as possible to the natural state based on the species characteristic for forest communities. While assessing the concept of biodiversity resulting from the naturalistic approach to the forest as a timeless good, it is necessary to take into account the diversity of plantings used and their multifunctionality. One of the functions is to designate crops for utility purposes, by creating a natural undergrowth, birdhouses, forest fringe plantings and enclaves of edible fruit plants. As part of the research, implementing the biodiversity of midfo…

The proposal to transform an old limestone quarry into a botanical garden with a rainforest zone: a case study

2019

Nowadays, a significant part of cities is tackling the problems with post-mining areas. This manuscript is an original research which shows possibilities of their reclamation. The aim of the article is to present the proposal of developing the closed limestone quarry and creating a botanical garden. The proposed spatial solutions allow for creating a new, tourist and recreation space, maintaining the natural heritage. The work also assumed carrying out a dendrological inventory, in order to determine the existing dendrofl ora. The required spatial, nature and communication analyses, which illustrate the current condition of the area and defi ne further design works, have also been carried o…
