Subsoil Reconstruction in Geostatistics beyond Kriging: A Case Study in Veneto (NE Italy)

The reconstruction of hydro-stratigraphic units in subsoil (a general term indicating all the materials below ground level) plays an important role in the assessment of soil heterogeneity, which is a keystone in groundwater flow and transport modeling. A geostatistical approach appears to be a good way to reconstruct subsoil, and now other methods besides the classical indicator (co)kriging are available as alternative approximations of the conditional probabilities. Some of these techniques take specifically into account categorical variables as lithologies, but they are computationally prohibitive. Moreover, the stage before subsoil prediction/simulation can be very informative from a hydro-stratigraphic point of view, as the detailed transiogram analysis of this paper demonstrates. In this context, an application of the spMC package for the R software is presented by using a test site located within the Venetian alluvial plain (NE Italy). First, a detailed transiogram analysis was conducted, and then a maximum entropy approach, based on transition probabilities, named Markovian-type Categorical Prediction (MCP), was applied to approximate the posterior conditional probabilities. The study highlights some advantages of the presented approach in term of hydrogeological knowledge and computational efficiency. The spMC package couples transiogram analysis with a maximum entropy approach by taking advantage of High-Performance Computing (HPC) techniques. These characteristics make the spMC package useful for simulating hydro-stratigraphic units in subsoil, despite the use of a large number of lithologies (categories). The results obtained by spMC package suggest that this software should be considered a good candidate for simulating subsoil lithological distributions, especially of limited areas.

Dimp-Hydro Solver for Direct Numerical Simulation of Fluid Microflows within Pore Space of Core Samples

The paper is devoted to a description of the DiMP-Hydro software package being developed at the Keldysh Institute of Applied Mathematics (Russian Academy of Sciences). It is intended to simulate microflows of single- and two-phase viscous compressible fluids with different rheology in spatial voxel domains. Such geometric models are relevant due to the development and widespread use of computer microtomography methods. One of the main areas of the application of this software package is the simulation of microflows within pore spaces of core (rock) samples. The simulation results can be used to determine the macroscopic properties of core samples (for instance, absolute permeability) and features of displacement processes at the micro level, which is one of main tasks of digital rock technology. The used mathematical models, numerical algorithms, and the software package are described. To describe the fluid dynamics, the regularized Navier–Stokes (for single-phase flows) and Navier–Stokes–Cahn–Hillard equations (for two-phase flows) are used. The regularization is based on the quasi-hydrodynamic approach, which is physically justified and makes it possible to use explicit stable numerical algorithms that are relatively simple to implement. The software package is parallel and focused on the use of high-performance computing systems. The results of the use of DiMP-Hydro to simulate microflows of fluid (including two-phase fluid) and gas (including moderately rarefied gas) in the pore space of core samples are presented.

. The possibility of application of the Infolytica software package to solve the main tasks of work is substantiated. The computer 3D-model of electromagnetic separator was verified by solving of test problem. Comparison of results of magnetic induction research for characteristic points obtained during 3D modeling of electromagnetic separator with data obtained during experimental research showed a fairly high consistency. An analysis of geometric dimensions influence on distribution of magnetic field in a polygradient matrix was carried out for a random sampling containing three structural variants of an electromagnetic separator, the working air gap of which varies over a wide range. It is shown that determination of magnetic flux distribution for other structural variants of matrix that located inside sampling can be carried out by interpolation. For selected variants, three-dimensional computer models of electromagnetic separator are developed, their geometric characteristics and physical properties are described. A numerical-field analysis of magnetic field spatial distribution in working air gap of polygradient matrix of electromagnetic separator was carried out using Magnet module of Infolytica software package. For three threedimensional models of electromagnetic system of separator, numerical values of magnetic induction and magnetic flux in working air gap of polygradient matrix in center of characteristic area are obtained. The obtained results for three models are compared and variant with rational parameters of working area of separator matrix is selected.

DscoreApp: A Shiny Web Application for the Computation of the Implicit Association Test D-Score

Several options are available for computing the most common score for the Implicit Association Test, the so-called D-score. However, all these options come with some drawbacks, related to either the need for a license, for being tailored on a specific administration procedure, or for requiring a degree of familiarity with programming. By using the R shiny package, a user-friendly, interactive, and open source web application (DscoreApp) has been created for the D-score computation. This app provides different options for computing the D-score algorithms and for applying different cleaning criteria. Beyond making the D-score computation easier, DscoreApp offers the chance to have an immediate glimpse on the results and to see how they change according to different settings configurations. The resulting D-scores are immediately available and can be seen in easy-readable and interactive graphs, along with meaningful descriptive statistics. Graphical representations, data sets containing the D-scores, and other information on participants' performance are downloadable. In this work, the use of DscoreApp is illustrated on an empirical data set.

Constraint-Induced Movement Therapy for Lower Extremity Function: Describing the LE-CIMT Protocol.

Constraint-induced movement therapy (CIMT) is comprised of a set of techniques shown to produce significant changes in upper extremity (UE) function following stroke and other disorders. The significant positive results obtained with the UE protocol have led to the development of LE-CIMT, an intervention to improve lower extremity (LE) function. However, some modifications of the UE protocol were needed, including omitting use of a restraint device, development of supervised motor training tasks to emphasize movement of the lower limb, and adaptation of the UE Motor Activity Log for the lower extremity. The LE-CIMT protocol includes: (1) intensive supervised training delivered for 3.5h/d for 10 consecutive weekdays, (2) use of shaping as a strategy for motor training, (3) application of a transfer package, and (4) strongly encouraging use of the more-affected LE with improved coordination. The transfer package consists of several strategies to facilitate transfer of the improved motor skills developed during supervised treatment to everyday situations. Research to date has yielded positive results. However, the intervention protocol continues to evolve. The purpose of this article is to describe the components of the complete LE-CIMT protocol to promote further development and investigation of this approach.

Silicate Rock-Based Fertilizers Improved the Production of Sugarcane Grown on Udipsamments Kediri, East Java, Indonesia

Improving the farming productivity and profitability of sugarcane in Indonesia requires an appropriate fertilization method. So, three types of silicate rock-based fertilizers were developed and tested in field condition. The main objectives of this research were to identify the effects of liquid-silicate rock fertilizer (LSRF) in addition to NPK, and granules of NP₇₀-Si and NP₁₀₀-Si on the growth and yield components of sugarcane grown on Udipsamments. A randomized complete block design was employed with the treatment consisting of F-0 (NPK) as the reference of fertilizer package, F-1 (NPK + LSRF applied onto the leaf), F-2 (NPK + LSRF applied to the soil), F-3 (NP₇₀-Si), and F-4 (NP₁₀₀-Si), and those were replicated in five blocks. Results reveal that the applications of those different fertilizer packages significantly affected the germination of seed buds, cane production, and sugar yield, but did not for the other growth and yield components. The order of its agronomic and economic effectiveness of the fertilizer packages, based on the value of either cane production or sugar yield, was F-2 > F-1 > F-4 > F-0 > F-3. Therefore, the use of the fertilizer package of F-2 (NPK + LSRF) may be promoted as an appropriate fertilization method to improve the farming productivity and profitability of sugarcane in Indonesia.
