Analytical solution of kinematic wave time of concentration for overland flow under green-ampt infiltration
2015
In this paper the well-known kinematic wave equation for computing the time of concentration for impervious surfaces has been extended to the case of pervious hillslopes, accounting for infiltration. An analytical solution for the time of concentration for overland flow on a rectangular plane surface is derived using the kinematic wave equation under the Green-Ampt infiltration. The relative time of concentration is defined as the ratio between the time of concentration of an infiltrating plane and the soil sorptivity time scale, depending on the normalized rainfall intensity and a parameter synthesizing the soil and hillslope characteristics. It is shown that for a more complex case (corre…
Pre-marital and pre-unional financial agreements and their circulation in the context of the new EU regulations 2016/1103 and 2016/1104
2021
Regulations (EU) 2016/1103 and 2016/1104 provide spouses and partners with the possibility to conclude agreements for the organization of their property regime but do not detail their content and structure. Moreover, while the possibility to conclude those agreements even prior to the marriage or the conclusion of a registered partnership is a valuable innovation in comparison with other European Regulations in family matters, some choices made by the European legislator on applicable law will likely be source of inconveniences. Furthermore, as for their recognition and enforcement in the participating Member States ? which will be based on the same rules enacted for decisions, authentic in…

Chapter 3 patterns and thresholds of runoff generation and sediment transport on some Mediterranean hillslopes
2005
Abstract Runoff and sediment transport data obtained from hillslopes in two limestone areas in southeast Spain are analysed in order to define spatial and temporal thresholds for sediment movement at the patch scale under Mediterranean semiarid and subhumid climatological conditions. The data discussed in this paper include a 7-year series of runoff and sediment collection in open Gerlach plots. The 136 events are analysed in relation to characteristics of rainfall, soil and soil surface components. In both cases slopes behave as a patchwork of runoff and runon areas and the size of the runoff or runon patches being dependent on the climatological conditions. These control the hydrological …
Cover crop management and water conservation in vineyard and olive orchards
2021
Abstract Sustainability in orchard crops is an important goal for farmers, decision-makers and consumers. The United Nations Sustainable Development Goals emphasize the importance of the soils in the Earth System to achieve sustainability and accomplish the Land Degradation Neutrality Challenge. Within the world agriculture land, olive and vineyards are within the eldest crops in the world, and they are also the ones with the highest degree of soil degradation. Cover crops (CC) are widely accepted as sustainable crop management that reduces soil and water losses, restores organic matter, increases biodiversity and fertility in degraded agriculture soils. The agriculture land must shift into…
Predicting maximum annual values of event soil loss by USLE-type models
2017
Abstract Previous experimental investigations showed that a large proportion of total plot soil erosion over a long time period is generally due to relatively few, large storms. Consequently, erosion models able to accurately predict the highest plot soil loss values have practical importance since they could allow to improve the design of soil conservation practices in an area of interest. At present USLE-based models are attractive from a practical point of view, since the input data are generally easy to obtain. The USLE was developed with specific reference to the mean annual temporal scale but it was also applied at the event scale. Other models, such as the USLE-M and the USLE-MM, app…
Exploiting historical rainfall and landslide data in a spatial database for the derivation of critical rainfall thresholds
2017
Critical rainfall thresholds for landslides are powerful tools for preventing landslide hazard. The thresholds are commonly estimated empirically starting from rainfall events that triggered landslides in the past. The creation of the appropriate rainfall–landslide database is one of the main efforts in this approach. In fact, an accurate agreement between the landslide and rainfall information, in terms of location and timing, is essential in order to correctly estimate the rainfall–landslide relationships. A further issue is taking into account the average moisture conditions prior the triggering event, which reasonably may be crucial in determining the sufficient amount of precipitation.…
Mätänevän velhon taidejulistus : intertekstuaalisen ja -figuraalisen aineiston asema Apollinairen L'enchanteur pourrissant teoksen tematiikassa ja sy…
2008
Ranskalainen modernisti Guillaume Apollinaire (1880-1918) marssittaa esikoisteoksessaan L’Enchanteur pourrissant (1909) kuolemattoman velhon haudalle vanhentuneen Troijan Helenan. Rapistuneen kaunottaren ohella mädäntyvän tietäjän lihaa saapuvat haistelemaan mm. viehkeytensä menettäneet juoruileviksi naisiksi muuttuneet haltijattaret, höperöityneet antiikin filosofit ja Raamatun kuolemattomat pyhimykset, jotka ovat unohtaneet uskonsa merkityksen. Apollinairen luomassa groteskissa maailmassa vanha myyttinen perintö kuolee ja mätänee samalla kun maailma vajoaa dekadenttiseen rappioonsa. Riikka Mahlamäki-Kaistisen tutkima Apollinaire on yksi tärkeimmistä 1900-luvun alun ranskalaisista kirjaili…
Mediterranean Great Conversation
2015
The exit from the Mediterranean emergency requires rethinking its identity in a new perspective. This means recognizing its legitimate role as a “Great Sea in Between”, as a cultural interface able to connect all the citizens that address to it, in everyday life and as individuals, involving them in a real “great conversation” based on the design disciplines. Design, Brand, Visual Identity, Packaging, Social Media, Fashion, Food, Architecture, Music may be powerful antidotes to the immobility of those who mourn a lost Mediterranean harmony and also a viable alternative to the ethnic closure led by the proponents of the Clash of Civilizations.
Prote Hyle. Notions of Matter in the Platonic and Aristotelian Traditions
2017
How do we experience matter? Does it present itself to the senses? Or is it only an empty substratum that cannot be grasped if deprived of all sensible qualities? Is it perceived as a continuum, or rather intellectually reconstructed through mental and logical forms? Or is it that the very idea of a continuum is itself the outcome of mental abstraction? The nature of matter has been a central issue for philosophy since its inception. The constant oscillation of ancient thought between ma er as indeterminateness that does not have a concept and does not even properly exist - and matter as a principle that allows one to think plurality and otherness, that reaches even into the realm of the in…
