Effective Practices in Mitigating Soil Erosion from Fields
2017
Soil erosion by water is a natural process that cannot be avoided. Soil erosion depends on many factors, and a distinction should be made between humanly unchangeable (e.g., rainfall) and modifiable (e.g., length of the field) soil erosion factors. Soil erosion has both on-site and off-site effects. Soil conservation tries to combine modifiable factors so as to maintain erosion in an area of interest to an acceptable level. Strategies to control soil erosion have to be adapted to the desired land use. Knowledge of soil loss tolerance, T, i.e., the maximum admissible erosion from a given field, allows technicians or farmers to establish whether soil conservation practices need to be applied …
Testing the Universal Soil Loss Equation-MB equation in plots in Central and South Italy
2019
Planning soil conservation strategies requires predictive techniques at event scale because a large percentage of soil loss over a long-time period is due to relatively few large storms. Considering runoff is expected to improve soil loss predictions and allows relation of the process-oriented approach with the empirical one, furthermore, the effects of detachment and transport on soil erosion processes can be distinguished by a runoff component. In this paper, the empirical model USLE-MB (USLE-M based), including a rainfall-runoff erosivity factor in which the event rainfall erosivity index EI30 of the Universal Soil Loss Equation (USLE) multiplies the runoff coefficient QR raised to an ex…
Impact of the Extraction Method on the Chemical Composition and Antioxidant Potency of Rosmarinus officinalis L. Extracts
2023
Rosmarinus officinalis L. is a dietary source that produces polyphenols as secondary metabolites. These natural compounds with potent antioxidant abilities are increasingly recommended as a supplement to inhibit oxidative stress. In the current work, we evaluated the impact of the extraction method on the chemical composition of R. officinalis extract, especially on the content of carnosic (CA) and rosmarinic (RA) acids using UPLC-MS-DAD as well as on their antioxidant potency. Four extracts of Tunisian rosemary were obtained from non-conventional extraction techniques:ultrasound-assisted extraction (UAE),supercritical extraction (SFE) and UAE and SFE combined ((UAE-SFE(I), UAE-SFE(II)). Th…
Population divergence in maternal investment and embryo energy use and allocation suggests adaptive responses to cool climates
2023
1. The thermal sensitivity of early life stages can play a fundamental role in constraining species distributions. For egg-laying ectotherms, cool temperatures often extend development time and exacerbate developmental energy cost. Despite these costs, egg laying is still observed at high latitudes and altitudes. How embryos overcome the developmental constraints posed by cool climates is crucial knowledge for explaining the persistence of oviparous species in such environments and for understanding thermal adaptation more broadly. 2. Here, we studied maternal investment and embryo energy use and allocation in wall lizards spanning altitudinal regions, as potential mechanisms that enable su…
The Relationship between Public Value and Change : Case Study on Public Value Creation in Relation to the Regional Government, Health and Social Serv…
2019
Master's thesis Innovative governance and public management ME523 - University of Agder 2019 A break first from Traditional Public Administration (TPA) and later New Public Management (NPM) has gradually offered new angles to the governance. For instance, Moorecreated an analogue to the private value creation,and as a result, the ideology of public value creation has emerged worldwide.Since then, scholars have developed a conceptual understanding of public value. Compared to the NPM public value management embraces post-competitive achievements and broader governmental goals. Yet, the empirical research on public value management, especially in the Finnish context, is rather unknown.This st…

Assessing risk perception over recidivist traffic offenders from a multi-group approach: how gendered could it be?
2022
ABSTRACT Objective: The core aim of this study was to examine the predictive role of demographic, psychosocial and driving features of Spanish drivers on their risk perception over recidivist traffic offenders, focusing on gender as a key differentiating factor. Method: For this cross-sectional study, it was analyzed the data gathered from a nationwide sample of 1,711 licensed drivers from the 17 regions of Spain (49% females, 51% males) with a mean age of 40.07 years, responding to a telephone-based interview on road safety issues. Demographic, driving-related and psychosocial factors were comparatively analyzed through robust tests and a bias-corrected MGSEM (Multi-Group Structural Equati…
Combining spatial prioritization and expert knowledge facilitates effectiveness of large-scale mire protection process in Finland
2020
Conservation resource allocation involves a complex set of considerations including species, habitats, connectivity, local to global biodiversity objectives, alternative protection and restoration actions, while requiring cost-efficiency and effective implementation. We present a national scale spatial conservation prioritization analysis for complementing the network of protected mires in Finland. We show how spatial prioritization coupled with regional targets and expert knowledge can facilitate structured decision-making. In our application, discussion between experts was structured around the prioritization model enabling integration of quantitative analysis with expert knowledge. The u…
Un sistema per la concimazione spazialmente variabile
2005
Lo scopo del lavoro è quello di misurare il tempo e la distanza di regolazione di un sistema per l’applicazione di fattori produttivi a dosi spazialmente variabili, progettato, sviluppato, messo a punto e già sperimentato positivamente per il diserbo dalla Sezione Meccanica del Dipartimento I.T.A.F. Tale sistema è stato sperimentato per la concimazione spazialmente variabile, installando, su uno spandiconcime ad azione centrifuga a due dischi di distribuzione opportunamente modificato, due diversi tipi di attuatori, collegati al sistema di regolazione delle luci di caduta del concime. E’ risultato che, a parità di variazione di dose, la distanza di regolazione del sistema, con entrambi gli …
La inscripción de la ciudadanía en la cuba neocolonial (1902-1919) : Sucinta referencia histórico-jurídica
2021
This historical-legal account brieflycovering 17 years of civil registration activity carried out during the neocolonial period by Municipal Judges and Secretaries, specifically that related to registration of Cuban citizens)becomes considerably relevant to understand and to godeeper into the origins of this complex process, as well asto achieve a re-encounter with the history of those who passed through those times, currently a hidden history in the shadows of Civil Registration offices, but still alive and thus allowing us to find all the beauty that there was in it.
