The content of a number of biogenic amines, their precursors, and derivatives was studied in the prefrontal cortex (PFC) of the brain of male Wistar rats exposed to chronic exposure to a low-intensity electromagnetic field of a Wi-Fi device (24 hours/day, 2.45 GHz, the power flux density did not exceed 583 μW/cm2, amounting to average – 0.46 ± 0.37 µW/cm2) during their early postnatal development. Changes in the content of dopamine, serotonin, their precursors, and metabolites in the PFC of the brain have been established, which determines the development of neurotransmitter disorders in the central nervous system, and subsequently the occurrence of behavioral disorders, the deterioration of social adaptation and cognitive abilities. The identified changes in the dopaminergic system of the PFC of the brain in rats at the early stages of their postnatal development indicate the need for a further hygienic assessment of the safety of long-term exposure to electromagnetic radiation on the body, especially on the brain. Further research in this direction will make it possible to determine neurotransmitter mechanisms underlying the adverse effects of low-intensity electromagnetic fields on the central nervous system, to assess their danger, and to correct the existing maximum permissible levels of electromagnetic radiation, taking into account the reaction of the neurotransmitter systems of brain structures to this type of impact.

Na narrativa da crise pela qual passa o Brasil, via de regra, responsabiliza-se o sistema político e o Estado como a fonte das crises nacionais; o grande vilão causador de gastos públicos. Na pauta da agenda política brasileira a questão da Previdência Social. Porém, pouco se fala sobre os problemas inerentes às estruturas e ao funcionamento do capitalismo brasileiro. Temos milhões de desempregados ou subempregados. Por que o Brasil é incapaz de gerar emprego e renda para seus cidadãos? Por que há altas taxas de violência no país? As falhas do sistema econômico que contribuem para o seu disfuncionamento e entrega de resultados para a sociedade é pouco debatida em nosso país.

NMR Fluid Substitution for Multimodal Carbonate Rocks
Authors:   Halliburton, Shao Wei , Singer Gabriela ,   Halliburton, Hursan Gabor ,   Saudi Aramco, Ma Shouxiang Mark ,   Saudi Aramco
Published: November 2024

Nuclear magnetic resonance (NMR) petrophysical interpretation is largely based on the correlation between NMR relaxation time and formation pore-size distribution, assuming the reservoir is fully saturated by the wetting fluid within the logging tools’ sensitive volume. NMR fluid substitution (FS), a set of methods to eliminate the effect of nonwetting fluids from NMR data acquired in partially saturated rocks, has been developed and established for simple, mostly unimodal pore systems. This paper evaluates the effectiveness of existing FS methods in multimodal carbonate pore systems and proposes a new technique to overcome the limitations of prior approaches in these types of reservoirs. Existing FS methods are subdivided into two approaches, based on (1) the SDR and Coates permeability estimations or (2) the Brownstein equation and thin-film model. Historically, these methods were validated for mostly sandstones and only a limited number of carbonate samples. This work thoroughly evaluates the effectiveness of the existing FS methods using 20 carbonate samples with a multimodal pore system. The plugs were prepared to mimic hydrocarbon charge and drilling mud-filtrate invasion and measured by NMR at 100% water, irreducible water, and residual oil saturations. Four different existing FS methods were applied to partially water-saturated data to approximate T2 distributions at 100% water saturation, and each approximation was subsequently compared with actual measurements of the fully water-saturated samples. Finally, this paper also presents a new FS method for carbonate multimodal pore systems. The new technique consists of a nonlinear inversion method that uses the Looyestijn water saturation profile model to describe the process of hydrocarbon displacing water and an inversion process that minimizes the L2 or L1 distances between the modeled and observed T2 distributions. The inversion derives the T2 distributions at 100% water saturation and the Looyestijn water saturation profile parameters. Existing FS methods in complex carbonate rocks may not be able to reconstruct the details of the pore-size distribution that is required to evaluate its modality. Also, they tend to overestimate mesoporosities and underestimate macroporosity significantly. The new FS method, validated by 20 carbonate samples with a variety of pore-size distributions, yields satisfactory results both in terms of T2 distribution matching and pore typing. The new method eliminates false, hydrocarbon-related bimodality from NMR data in unimodal pore systems while it correctly retains the bimodal T2 distribution where the fully water-saturated NMR spectrum is bimodal. Compared with the existing FS methods, the new FS processing performs well for all carbonate pore-size distribution patterns. This method increases the accuracy of NMR-based pore size and rock-type evaluation in partially hydrocarbon-saturated, complex carbonate pore systems.
Dielectric Characterization of Surface Relaxivity
Authors:   University of Houston, Funk James , Myers Michael ,   University of Houston, Hathon Lori ,   University of Houston
Published: November 2024

NMR and dielectric measurements provide unique petrophysical tools to probe the molecular dynamics of restricted geometries. Both techniques exhibit time-dependent relaxations sensitive to electromagnetic surface interactions and sensitivity to diffusion length scales in the case of NMR relaxation. However, diffusion rates typical for pore fluids limit the accessible length scales probed with NMR. Dielectric measurements provide additional length scale interactions and measurements that can be incorporated with conventional NMR. These clarify the relaxation time T1 and T2 size assignments typically represented by r1 and r2 surface relaxivity and define the lateral extent of the “fast diffusion limit.” Using protocols established with the coupled physics used in magnetic resonance electrical properties tomography (MREPT) for imaging dielectric properties of tissues, we adapt a dielectric permittivity differential length to area correlation based on Maxwell’s equations. An established staged differential effective medium model for matrix and vug dielectric dispersion and a dielectric-T2 mapping technique are used to evaluate the NMR relaxation, diffusion, and formation factors based on measured length scales from scanning electron microscope (SEM) images of the matrix and micro-CT images of the vug system. Correlated NMR and dielectric measurements during spontaneous brine imbibition provide an additional technique to address surface relaxivity by comparing changes in dielectric permittivity in parallel with characterized surface relaxation rates (T1S or T2S). Rates are compared with BPP model correlation times established through dry matrix high-frequency limit dielectric relaxation and T1 NMR dispersion based on comparative 2 MHz and 23 MHz T1 distributions. The dielectrically classified T2 distributions show good correlations with petrophysical properties and image-based size distributions. Modeled surface relaxivity in the matrix fraction falls within the expected range with vug values related to the overlap in the distributions. The technique uses the extensive dynamic mobile charge length scales from dielectric measurements (Maxwell-Wagner effect) to refine our interpretation of easily measured NMR multi-exponential response. Although based on carbonates with clay-free surface conductance, adaptation to scaled clastic dielectric dispersion measurements is proposed.

In order to support production processes at the Oktyabrsky deposit of rich sulfide ores at a depth of 2000 m two exploration workings were driven in 2020-2023 at the Levels of -1650m and -1750 m. with a length of about two kilometers each. In order to provide ongoing mining operations with a forecast of the geomechanical state of the rock mass, field studies were performed in advanced boreholes using ultrasonic logging (UL), borehole telemetry, and core disking. The UL method is used to study the elastic properties and fracturing of rocks. The fracturing of the bore of the advanced boreholes and the presence of various geological and structural heterogeneities are estimated by the telemetry method. The core disking method is based on the ability of hard rocks to brittle fracture. It is established that the vector of the main compressive stresses acts in the rock mass of the studied workings in different directions. Individual cases of identifying the core disking zones and "tracks" on the periphery of the advanced boreholes are not representative in their parameters for classifying these sites as "rock bump hazardous". Thus, a combination of the obtained data proves the efficiency of the applied forecast of the geomechanical state of the advance boreholes, while the information on the geomechanical state of the rock mass in the vicinity of the advance boreholes made it possible to timely make recommendations regarding the mining prcedures in order to ensure the stability of the workings being constructed.

Published: November 2024

The objectives of the study were to select the parameters for a development drift with account of the effect the mining operations have on formation of the gas dynamic phenomena, to develop a method of advance deformation and degassing of the coal seam, to clarify the cause-and-effect regularities in formation of the energy and dynamic interaction processes in the coal-rock massif and to justify the safe face advance criterion. The cause-and-effect method of comparing the guiding documents with the real characteristic of the outburst coal showed that the properties and attributes in the recommendations do not reflect the gas-dynamic hazard properties. Different ingredients and facies conditions of the coal seam formation have not been taken into account. The hazard of the coal seams is represented by irrelevant properties, and the interpretation of this hazard as a spontaneous gas outburst from the coal seam or the processes of energy accumulation and flow in the coal-rock massif covers the development of real methods to forecast and prevent this phenomenon. The article for the first time ever formulates a new hypothesis of the gas-dynamic phenomena in mining workings. In contrast to the existing concepts, the gas-dynamic phenomenon is a natural phenomenon that is local in nature and is a reaction of the stressed-and-strained rock massif to the advance of the coal face. The method preventing a sudden outburst of methane from the coal seam is methane capture in the relief holes using a vacuum pump and its removal via pipes to the ventilation workings or to the surface. With the depth of the relief holes of 30 metres, the face advance rate can be increased up to 13 metres per day.

The history of applying computer technologies in the mining industry goes back for more than half a century. Research activities in the 60s-70s of the last century were focused on modeling of deposits, machine representation of mining and geological information and creation of mathematical models of surface and underground mines. The first automated control systems started to emerge at mining enterprises during this period. The main trends in application of computer technologies, including geological modeling, support of surveying and design, as well as planning of mining operations, were established by the 1980s. Several industry programs to create computer-aided design systems for the mining industry were implemented in the USSR in the 1980s. However, despite significant achievements, the development of these systems faced a number of challenges, such as a lack of software unification and a shortage of technical means at workplaces. With the collapse of the Soviet Union, many scientific teams fell apart, and the previous developments were lost. Modern developments in the mining and geological information systems (MGIS) in the post-Soviet countries were initiated by new teams in the 1990s. The withdrawal of foreign MGIS from Russia, on the one hand, opened a window of opportunities for the Russian developers, but, on the other hand, challenged them with a difficult task to create a domestic full-featured MGIS in the shortest time possible, i.e. within 2-3 years.

A set of new regional (segmented) models of MOS transistors is proposed. In the models, the current in saturation is not considered independently, but as an extrapolation of the current of the physical model in the unsaturated (linear) mode by Padé approximant. The first two coefficients of the approximant are determined from the condition of continuity of the transistor current at the boundary of the saturated region along with two derivatives; the remaining coefficients are determined by parametric optimization based on measured current-voltage characteristics. This saturation current model is invariant with respect to the model for the unsaturated mode and the physics of processes at current saturation. These models were created primarily for simulating transistors manufactured using various wide-gap semiconductor technologies: silicon carbide, gallium nitride and diamond. The results of modeling GaN and SiC transistors with low root mean square error are presented.
