Labile nitrogen, carbon, and phosphorus pools and nitrogen mineralization and immobilization rates at low temperatures in seasonally snow-covered soi…

2006

Surface mineral horizons from four ecosystems sampled in the northwestern Italian Alps were incubated at −3 and +3°C to simulate subnivial and early thaw period temperatures for a seasonally snow-covered area. The soil profiles at these sites represent extreme examples of management, grazed meadow (site M) and extensive grazing beneath larch (site L) or naturally disturbed by avalanche and colonized by alder (site A) and the expected forest climax vegetation beneath fir (site F). Changes in labile pools of nitrogen (N) and phosphorus (P) were active at all sites at both temperatures during 14 days of laboratory incubation. Ammonium was the dominant inorganic form of total dissolved N (TDN),…

Natt, Sharon. 2016. Exploring Human Rights Conceptualisations in the United States: A study into knowledge and attitudes of participants connected to a social justice NGO. University of Jyväskylä. Department of Education. Concepts of human rights are present within our social, global and geo-political frameworks, yet their understandings are subject to infinite influences and interpretations. This localised and exploratory study importantly addresses a gap in previous research by investigating such conceptualisations against the backdrop of the United States. Centring on knowledge and attitudes, it focuses specifically on US participants with a connection to a social justice NGO. Representa…

Análisis conjunto y espacios naturales: una aplicación al Paraje Natural del Desert de les Palmes

2007

We use stated preference methods to analyze consumer preferences on the attributes of protected natural areas and to estimate the willingness to pay for reducing the risk of fires in the site. For the first goal, conjoint analysis is used. Three attributes are considered: biodiversity, dimension of the natural area and the economic contribution that would have to be made for its maintenance and preservation. The willingness to pay for reducing the risk of fires has been estimated using choice experiment. The data have been gathered from a mail survey conducted among people living near the Desert de les Palmes Park, a protected area located in the Valencian Community (Spain). En el trabajo s…

Augsnes mezofaunas struktūra Engures ezera dabas parkā

2018

Bakalaura darba pētījums veikts Engures ezera dabas parka ekoreģionā un tā tuvākajā apkārtnē. Darbā tiek aprakstīta augsnes mezofauna un analizēta tās veidotās struktūras dažādos biotopos un to parauglaukumos, kas iekļauti ILTER (International Longt Term Ecological Research network) programmā. Bakalaura darbā iekļauta vispārīga informācija par augsnes faunu un parauglaukumos konstatētajiem mezofaunas pārstāvjiem. Pētījums ir veikts sešos biotopos. Katrā parauglaukumā noteikts mezofaunas taksonomiskais sastāvs, struktūra un tās blīvums. Bakalaura darba izstrādes laikā autore apguva augsnes mezofaunas ievākšanas un noteikšanas metodiku, kā arī ieguva zināšanas un izpratni par mezofaunas nozīm…

Biodegradation of organophosphorus pesticides by soil bacteria.

2009

A number of studies in the 1980s and 1990s showed that crop-protection products, applied to drained fields, could move downwards through the soil profile and to the groundwater. Organophosphorus insecticides (OPs) are used all over the world for crop protection, for other agricultural practices such as sheep dipping and, in aquaculture, for the control of sea lice. Ops besides showing a specific neurotoxicity and have also been related to various modern diseases, including Creutzfeldt–Jakob (CJD) and the Gulf War syndrome. Although OPs are less persistent than Organoclorine pesticides (OCs), they still constitute an environmental risks thus increasing the social concern about their levels i…

Influence of Calcium Carbonate Nanoparticles on the Soil Burial Degradation of Polybutyleneadipate-Co-Butylenetherephthalate Films.

2022

A polybutyleneadipate-co-butylenetherephthalate (PBAT) sample, commercially known as Ecoflex®, was processed via melt extrusion with CaCO3 nanoparticles coated with a hydrophobic coating. Blown films of PBAT and two composites with nanofiller (2% and 5%wt) were prepared and degradation tests in soil at 30 °C up to 180 days were carried out with weight loss measurements. Furthermore, biodegradation test according to ISO 14851 was carried out at 30 °C. The effect of CaCO3 on soil burial degradation was assessed by surface wettability and SEM. ATR-FTIR and XPS analyses highlighted chemical modifications induced by soil degradation. CaCO3 nanoparticles decreased surface wettability …
