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
La missió en la vida. Notes sobre «Camins de França» de Joan Puig i Ferreter
2005
This article approaches the task of analyzing the autobiographical activity of Joan Puig i Ferrater. Particular attention is paid to «Camins de França», one of the most outstanding autobiographies of the twentieth century literature. The literary production of Puig i Ferreter turns around a series of basic characteristics: life like an initiation journey, life like a search of the affirmation of his own personality, and the sense of sensuality. All in all, the author conceives his office of artist as an adventure in search of his own essence.

Coupling of iron and dissolved organic matter in lakes–selective retention of different size fractions
2023
AbstractIncreasing concentration of iron (Fe) is observed in many boreal lakes, such as for the present study in Oslo Østmark, SE-Norway (1983–2018). As Fe-regulating processes are complex and dynamic, the link between mobilizing and retention processes is still not well understood. A seasonal study (2017–2018) from two headwaters, with medium and high dissolved organic matter (DOM) concentrations, showed that the loading of Fe to the lakes was highly dependent on flow conditions. Significantly higher values of Fe were related to autumn and winter periods with high runoff of highly colored and aromatic DOM compared to a severe drought period with minimum Fe values in the lakes. Compared to …
Local cubic splines on non-uniform grids and real-time computation of wavelet transform
2017
In this paper, local cubic quasi-interpolating splines on non-uniform grids are described. The splines are designed by fast computational algorithms that utilize the relation between splines and cubic interpolation polynomials. These splines provide an efficient tool for real-time signal processing. As an input, the splines use either clean or noised arbitrarily-spaced samples. Formulas for the spline’s extrapolation beyond the sampling interval are established. Sharp estimations of the approximation errors are presented. The capability to adapt the grid to the structure of an object and to have minimal requirements to the operating memory are of great advantages for offline processing of s…
Using static and dynamic indicators to evaluate soil physical quality in a Sicilian area
2016
Both capacitive indicators derived from the water retention curve and dynamic measurements of the flow-weighted mean pore radius, R0, were used to assess the soil physical quality of two agricultural areas (cropland and olive orchard) and two natural areas (grassland and managed woodlot plantation) potentially subject to soil degradation. The overall idea of the study was to investigate whether a dynamic indicator quantitatively derived from hydraulic conductivity measurements could be used to supplement the traditionally applied capacitive indicators retrieved from water retention measurements. According to the available criteria, only the surface layer of the cropland site showed optimal …
Developing and testing a discrete event simulation model to evaluate budget impacts of diabetes prevention programs
2020
Type 2 diabetes (T2D) is one of the most rapidly increasing non-communicable diseases worldwide. Lifestyle interventions are effective in preventing T2D but also resource intensive. This study evaluated with discrete event simulation (DES) the relative budget impacts of three hypothetical diabetes prevention programs (DPP), including group-based contact intervention, digital program with human coaching and fully automated program. The data for simulation were derived from research literature and national health and population statistics. The model was constructed using the iGrafx Process for Six Sigma software and simulations were carried out for 10 years. All simulated interventions produc…

Nenodrošinātā kreditora tiesību īstenošanas problemātika mantojuma lietā
2019
Bakalaura darba “Nenodrošinātā kreditora tiesību īstenošanas problemātika mantojuma lietā” mērķis ir noskaidrot tiesiskā regulējuma gadījumus, kas ir nenodrošinātā kreditora tiesību īstenošanas problemātikas pamatā mantojuma lietā. Tāpat mērķis ir noskaidrot, vai nenodrošinātā kreditora kā tiesību subjekta tiesības ir samērotas ar citu tiesību subjektu tiesībām un pienākumiem mantojuma lietā. Darbā autore, aplūkojot katru mantojuma lietas posmu, sākot no mantojuma atklāšanās līdz tiesību pārņēmēju noskaidrošanai vai mantojuma lietas izbeigšanai, ir analizējusi problemātikas rašanās pamatus un darba noslēgumā sniegusi priekšlikumus, kā risināt aplūkotos problemātikas gadījumus.
