A pedotransfer function for estimating the soil erodibility factor in Sicily
2009
The soil erodibility factor, K, of the Universal Soil Loss Equation (USLE) is a simple descriptor of the soil susceptibility to rill and interrill erosion. The original procedure for determining K needs a knowledge of soil particle size distribution (PSD), soil organic matter, OM, content, and soil structure and permeability characteristics. However, OM data are often missing and soil structure and permeability are not easily evaluated in regional analyses. The objective of this investigation was to develop a pedotransfer function (PTF) for estimating the K factor of the USLE in Sicily (south Italy) using only soil textural data. The nomograph soil erodibility factor and its associated firs…
Enhanced Thin-Film Transistor Performance by Combining 13,6-N-Sulfinylacetamidopentacene with Printed PEDOT:PSS Electrodes
2011
Bottom-contact/bottom-gate organic thin-film transistors (OTFTs) are fabricated using a soluble pentacene precursor (13,6-N-sulfinylacetamidopentacene; SAP) and inkjet printed PEDOT:PSS electrodes on bare SiO2 dielectrics. Saturation mobility, Ion/Ioff ratio, and threshold voltage parameters, respectively, of 0.27 cm2 V−1 s−1, 105, and −4.25 V were measured under ambient conditions after the thermal conversion of SAP to pentacene in 100 μm long channel OTFT devices. The results obtained by the above solution approach are comparable to that of vapor-phase grown pentacene-based OTFTs with photolithographic gold contacts and organic buffer layers and/or inorganic injection layers. The present …

Using the centre-periphery framework to explore human-carnivore relations
2023
Unidad de excelencia María de Maeztu CEX2019-000940-M Living alongside carnivores can incur both costs and benefits on people's lifeways. While positive outcomes of carnivore presence can foster coexistence, negative relations with carnivores can trigger carnivores' killing and undermine their conservation. In response to this, conservation efforts increasingly focus on promoting positive human-carnivore relations, most often through improvements in the flow of economic benefits from carnivores to local communities. However, there is a question mark over the effectiveness and potential consequences of market-based instruments for carnivore conservation. To understand the opportunities and p…
Artificial Neural Networks for Predicting the Water Retention Curve of Sicilian Agricultural Soils
2018
Modeling soil-water regime and solute transport in the vadose zone is strategic for estimating agricultural productivity and optimizing irrigation water management. Direct measurements of soil hydraulic properties, i.e., the water retention curve and the hydraulic conductivity function, are often expensive and time-consuming, and represent a major obstacle to the application of simulation models. As a result, there is a great interest in developing pedotransfer functions (PTFs) that predict the soil hydraulic properties from more easily measured and/or routinely surveyed soil data, such as particle size distribution, bulk density (&rho

Amperometric Biosensor and Front-End Electronics for Remote Glucose Monitoring by Crosslinked PEDOT-Glucose Oxidase
2018
Focusing on the interplay between interface chemistry, electrochemistry, and integrated electronics, we show a novel low-cost and flexible biosensing platform for continuous glucose monitoring. The amperometric biosensing system features a planar three-electrode structure on a plastic substrate, and a wireless near-field communication-powered electronic system performing sensor analog front-end, A/D conversion, digital control, and display tasks. The working electrode is made of electropolymerized poly (3,4-ethylenedioxythiophene) film onto a polyethylene terephthalate/gold electrode followed by immobilization of cross-linked glucose oxidase by glutaraldehyde. The advantages offered by such…
Funzioni di pedotrasferimento per la determinazione della curva di ritenzione idrica dei suoli siciliani
2009
Il ricorso alle funzioni di pedotrasferimento (PTF) rende possibile una stima relativamente agevole delle caratteristiche di ritenzione idrica del suolo. Una riproduzione accurata delle misure per un’area di interesse presuppone però l’accertamento delle prestazioni delle PTF esistenti ed, eventualmente, lo sviluppo di PTF alternative. Utilizzando 217 curve di ritenzione misurate in Sicilia, nell’indagine è stata dapprima verificata l’applicabilità di alcune delle più diffuse PTF disponibili in letteratura. Tale verifica ha evidenziato che i risultati migliori competono alle PTF che includono, tra le variabili indipendenti, la densità apparente del suolo. Poiché tale proprietà fisica non se…
Pedotechnique application and soil security in intensive viticulture: an (im)possible link!
2018
Since ancient times Man and Soil have experienced interwoven links. Nowadays soil scientists continue to stress such links highlighting the importance of soil to provide man’s growing demand for food, water and energy, and also the soil’s im- portance in providing ecosystem services that affect climate change, human health and biodiversity. In soil management for agricultural purposes, pedotechniques to tailor soils suita- ble for table grapes cultivation in large-scale farming are used to get substantial fi- nancial returns. However, farmers in tailoring soils for high income crops, fre- quently do not take into account the fundamental objective of the pedotechnique, i. e. to meet the need…
