A review of runoff generation and soil erosion across scales in semiarid south-eastern Spain

2011

Climate, lithology, soil and especially, intense land use/cover changes, make SE Spain very vulnerable to runoff generation and water erosion leading to loss of nutrients and organic matter and to infrequent but devastating floods, reservoir siltation and mass failures. This susceptibility has led to heavy economic investment and research efforts since the 1980s, making this region a worldwide reference for understanding the hydrology and geomorphology of semiarid ecosystems. Runoff and soil erosion have been intensively studied throughout the last decades in various natural ecosystems as well as in abandoned farmlands. Research has considered a wide range of methods and spatial and tempora…

Monitoring soil volume wetness in heterogeneous soils by electrical resistivity. A field-based pedotransfer function.: A field-based pedotransfer fun…

2014

11 pages; International audience; Modern irrigation techniques require accurate, rapid, cost-effective, spatial measurement of soil moisture. Electrical Resistivity Tomography (ERT) meets most of these requirements, but needs to be calibrated for each use because it is very sensitive to differences in soil characteristics. In this study, a pedotransfer function approach is used to remove the need for site-specific calibration, allowing ERT to be used directly to measure soil moisture. The study site was a hillslope vineyard, where eight calcaric-cambisol soil profiles were identified. From 2012 to 2013, 23 000 soil volume wetness measurements were acquired by Time Domain Reflectometry, and …

The fragility of Finnish parliamentary democracy at the moment when Prussianism fell

2019

The Finnish case is in many ways illustrative of the complexities of democratisation after World War I. Finland found itself at the nexus of a Swedish constitutional tradition, legalism and ideological controversies adopted from Imperial Germany, the radicalised Russian Revolution, and Western parliamentary democracy. After having been a model for reformers demanding women’s suffrage, for instance, the country found itself in autumn 1918 going in the opposite direction to almost all other European countries. This article analyses the fragility of Finnish parliamentary democracy then, contrasting it with longer-term trends supportive of democratisation. ‘Democracy’ had been the goal for mos…

Thomas Hobbes ja pelon taloustiede

2013

Thomas Hobbesia (1588-1679) pidetään usein yhtenä ”kapitalismin isistä”. Näkökulma on kuitenkin sinänsä ongelmallinen, että Hobbes ei juurikaan kirjoittanut pääomista tai tuotannosta. Hänen poliittinen ajattelunsa oli vastakkaista Englannin nousevan porvariston pyrkimyksille toteuttaa vero- ja kauppavapaus. Hobbes piti aikansa Alankomaita huonona esimerkkinä pääoman ja vapauden liitosta.Kysymys omistuksesta löytyy kuitenkin Hobbesin yhteiskuntateorian perustasta. Kuuluisassa ”luonnontilassa” ei voi Hobbesin mukaan olla omistusta, koska vain oikeusjärjestelmä yhdessä väkivallan monopolin kanssa kykenee takaamaan sen. Hobbes kannustaa ihmisiä tuottavaan elämään ja näkee valtion tehtävänä sell…

Impact of organizing working hours (5 shifts of 8 hours per week vs 3 shifts of 12 hours per week) on health and job strain

2015

This article gives an account of research carried out on working hours in a French hospital and specifically the impact on two ways of organizing working hours (12 hour shifts vs 8 hour shifts) on workers health and job strain as perceived by the health care providers. Based on 255 questionnaires, this research indicates that the health care providers who work in 12 hour shifts and 8 hour shifts have the same perception of their health and job strain. However, there are some differences: the health care providers working in 12 hour shifts feel less fatigue and emotional exhaustion than the health care providers working in 8 hour shifts. We discuss these results taking into account that: i) …

Proposal for a new diagnostic horizon for WRB Anthrosols

2009

Abstract To investigate man's role in the creation and evolution of soils in areas of large scale farming, and to investigate the main morpho-descriptive aspects of the related soils, a survey was carried out in south eastern Sicily, Italy, where, as common to other regions of the Mediterranean basin, there are wide areas with anthropogenic soils due to large scale farming activity. The complex genesis pattern of these anthropogenic soils, which shows a double sequence of man-made horizons, sideways oriented to the soil surface, does not allow their classification as Technosols, because their composition is not dominated or strongly influenced by artefacts or human-made materials as is the …

PLANTING DENSITY AND PRUNING METHOD AFFECT EGGPLANT SOILLESS CULTURE

2007

The aim of this research was to evaluate the effects of two planting densities (1.6 plants-m-2 or 2.5 plants-m-2) and two pruning methods (two or four stemmed plants) on eggplant cultivars Black Bell and Longo in soilless culture. The research was carried out in 2003-2004 in the Northern coast Sicily. Eggplant plug plants were transplanted in a heated glasshouse in polystyrene containers (80 cm in length, 25 cm in width, 20 cm in height) filled with coconut coir dust. The experimental design was a split-split plot. Fruit production from January to April increased significantly as planting density increased. Irrespectively of the cultivars, four stemmed plants gave higher yields than two ste…

EFFECTS OF PRE-PLANT SOIL TREATMENTS ON STRAWBERRY IN SICILY

2014

The 2005 ban by Italy of methyl bromide (MB) has resulted in significant crop management difficulties in pre-plant soil dis-infestation. We report two pre-plant soil treatment techniques and their effects on the performance of new cultivars and selections tolerant to the main root pathogens. The plants grown in soil treated with chloropicrin + 1,3 dichloropropene were the most productive. While neither treatment affected average berry weight, soluble solids content or titratable acidity, the treatment × cultivar interaction was significant and fruits from plants grown in treated soil were firmer than control s. Selection PA 260 and cultivar Florida Fortuna were the earliest, three selection…

Relationship between cobalt, copper and zinc content of soils and vegetables

1992

The relationship between cobalt, copper and zinc content of soils and the vegetables grown in them is discussed. Samples of soil and edible vegetables were taken from 15 different sites, corresponding to four agricultural areas exposed to different degrees of environmental pollution: high industrial and traffic, high industrial and urban, and low industrial and urban pollution. Elements were determined by atomic absorption spectroscopy. Variance analysis (ANOVA) was applied to cobalt, copper and zinc content of vegetables and soils in order to detect significant differences among soils of different areas and the vegetables grown there. The possible relationship between the heavy metal conte…
