Bioenergy Production and Social Sustainability on Finnish Farms

2011

Problems related to energy production have become a significant social issue, also regarding rural areas. There is an apparent need to establish a model for sustainable energy production that would encompass economic, environmental and social sustainability (Elliott 2000). One important solution to reducing carbon dioxide emissions, as well as addressing the depletion of fossil fuel resources, lies in the renewable natural resources that exist in rural areas. However, sustainable and reasonable utilization of these resources is not simple and requires specific analysis of different production models (Mol 2007). Simultaneously, one must consider how these rural resources can be utilized and …

Integrated stratigraphy of the Oxfordian global stratotype section and point (GSSP) candidate in the Subalpine Basin (SE France).

2014

44 pages; International audience; An integrated biostratigraphic approach, based on ammonites, calcareous nannofossils, dinoflagellates, combined with sedimentology, carbon-isotope and physical stratigraphy, is proposed for the Subalpine Basin (Thuoux and Saint-Pierre d'Argençon sections). Within the expanded marl deposits of the Terres Noires Fm., the Callovian-Oxfordian boundary is particularly well defined by ammonite taxa from different families (i.e. Cardioceratidae, Oppeliidae, Aspidoceratidae and Perisphinctidae), calcareous nannoplankton (first occurrence of large-sized Stephanolithion bigotii) and dinoflagellate cysts (first occurrence of Wanaea fimbriata). This precise biostratigr…

Oxygen isotopes in mammal bone phosphate: A new tool for paleohydrological and paleoclimatological research?

1984

Abstract Oxygen isotope analyses of water in blood of humans and domestic pigs indicate that the oxygen isotope fractionation effects between ingested water and body water are the same in all specimens of the same species. The δ 18 O of body water has been shown to vary linearly with the mean δ 18 O of local meteoric water. This conclusion also holds for the bone phosphate. Thus, δ 18 O ( PO 3− 4 ) values of unaltered fossil bones from humans and domestic pigs can be used to reconstruct the δ 18 O values of local meteoric waters during the life-times of the mammals. Such data can be used for paleohydrological and paleoclimatological studies both on land and at sea.

TYPO-CHRONOLOGIE DES CÉRAMIQUES DU GROUPE RHIN-SUISSE-France -ORIENTALE (R.S.F.O.) DANS LA RÉGION DIJONNAISE :

2009

The archaeological site of the Pré-du-Plancher is located to the east of Dijon (Burgundy, Côte-d’Or), at the footof a limestone hill in the Basmont valley. This site, dated from the late Bronze Age, is the first to include a stratigraphicalsequence for this period in Burgundy. The settlement comprises of three buildings and several dumps containing potteryfinds. The study of the pottery as well as the site’s stratigraphy clearly identifies three chronological periods dating from Late Bronze Age IIb to Late Bronze age IIIa (French chronology) or Hallstatt A2 / B1 (German/Swiss chronology). Culturally, the site belongs to the Rhin-Suisse-France-Orientale group, the first phase showing influen…

BIOMASS UTILIZATION AS A RENEVABLE ENERGY SOURCE IN POLISH POWER INDUSTRY – CURRENT STATUS AND PERSPECTIVES

2015

The depletion of the conventional energy sources, as well as the degradation and pollution of the environment by the exploitation of fossil fuels caused the development of renewable energy sources (RES), including biomass. In Poland, biomass is the most popular renewable energy source, which is closely related to the obligations associated with the membership in the EU. Biomass is the oldest renewable energy source, and its potential, diversity and polymorphism place it over other sources. Besides, the improvement in its parameters, including an increase in its calorific value, resulted in increasing use of biomass as energy source. In the electric power industry biomass is applied in the p…

A new replacement name for the fossil spider Veterator Petrunkevitch, 1963 (Arthropoda: Arachnida: Araneae)

2021

A junior homonym was detected in the genera of fossil Araneae and the following replacement name is proposed within the family Trochanteriidae: Neoveterator Ceccolini & Cianferoni nom. nov. pro Veterator Petrunkevitch, 1963 nec Laws, 1944. Eight new combinations (comb. nov.) are proposed.

The Dolia Defossa and viticulture at Vagnari

2022

At Vagnari, the fabric of the dolia defossa was distinctively different from that present in all the other ceramics from the site, as it was a distinctive orangey-red with black, glassy particles and reddish-brown grit fragments. The surviving lid fragment, on the other hand, is made of a fairly fine buff clay, suggesting it was made somewhere else. It is not unusual that dolia and lids might be made of different clays and in different workshops, as they are in Gallia Narbonensis, where some analysed lids were made in Rome, but the vessels were local. The recognition that it is important to conduct fabric analyses on dolia retrieved in archaeological excavations, whether on land or in the s…

Consistent phenological shifts in the making of a biodiversity hotspot: the Cape flora

2011

Abstract Background The best documented survival responses of organisms to past climate change on short (glacial-interglacial) timescales are distributional shifts. Despite ample evidence on such timescales for local adaptations of populations at specific sites, the long-term impacts of such changes on evolutionary significant units in response to past climatic change have been little documented. Here we use phylogenies to reconstruct changes in distribution and flowering ecology of the Cape flora - South Africa's biodiversity hotspot - through a period of past (Neogene and Quaternary) changes in the seasonality of rainfall over a timescale of several million years. Results Forty-three dist…

Population dynamics of fossorial water vole (Arvicola terrestris scherman): a land use and landscape perspective

1997

Abstract This study investigates the effect of land use, and landscape composition and structure on the population dynamics of fossorial water vole (Arvicola terrestris scherman Shaw). Water vole populations were monitored from 1989 to 1994 in the Doubs department, France, by using index methods. Land use patterns were studied based on agriculture and forestry data from the French Ministry of Agriculture collected in 1956, 1970, 1979 and 1988. Grassland quality and landscape structure were studied based on field transects, combined with the assessment of landscape structure from maps at 1:25,000 scale. Outbreaks of water vole populations occurred as a wave, spreading from epicentres over mo…
