Published: January 2025

In this paper, we present an innovative workflow that allows the performance of coupled direct shear tests in a large direct shear rig utilising whole core samples extracted from wellbores to enable the investigation of fault generation and reactivation processes using rock materials that more closely relate to a given underground study area, whilst minimising the need for large outcrop or synthetic rock samples in experimental campaigns. The methodology involves the preparation and shearing of a composite sample made from the intact (i.e., not fractured) core sample and cement paste and then sub-coring of the sheared composite sample to obtain a 38 mm diameter plug containing the fault zone for further investigation in axisymmetric triaxial setups. The examination of the sheared plug obtained in the first trial confirmed the generation of the fault zone at the predicated angle and location, evidencing the technique's success. It represents a significant advance in our capabilities to characterise sheared materials from diverse depth ranges and geological contexts, complementing field observations and helping to address several aspects relevant to industry and academia.

1. INTRODUCTION

Tectonic and anthropogenic stress changes within and near an underground reservoir can significantly impact the integrity of faults and fractures, potentially leading to fault reactivation, with a follow-on impact on the reservoir's containment (vide, e.g., Wriput and Zoback, 2000). Therefore, it is crucial to assess the mechanical integrity of these discontinuities and understand the alterations in fluid flow along or across them in response to changes in the surrounding stress state. This knowledge is essential for the safe and effective storage or production of natural gas, CO2, and hydrogen accumulations.

In this context, experiments that replicate fracture or fault generation and their reactivation while monitoring changes in their hydraulic conductivity and microseismic response can provide insightful information for the understanding of faults’ static and dynamic behaviour and better predict how geological events or injection or production strategies could affect the reservoir's overall stability and sealing potential.

Authors: Li Xiongrong , Dong Baohong , Huang Sha , Li Bin , Li Jing , Wei Yaoran , Yang Heng
Published: January 2025

During the drilling of hydrate-bearing formation, temperature and pressure differences between the reservoir and the wellbore cause the decomposition of hydrates around the wellbore. It reduces the mechanical properties of the reservoir and leads to wellbore instability. Most of the research primarily focuses on the stress disturbances around the well due to temperature and pressure changes, with relatively few studies addressing the stability of hydrate-bearing wellbores during the invasion of drilling fluids. This study investigates the mechanical response characteristics of hydrate-bearing formation during the drilling process, based on a dual-coupling platform for hydrate decomposition phase transition and geomechanics. The platform integrates the thermal–hydro– chemical module and the mechanical analysis module using TOUGH+HYDRATE and FLAC3D software, respectively. An interpolation algorithm is employed to transfer and call seepage field parameters and mechanical field parameters between the two software programs. This study considers changes in hydrate saturation, formation temperature, and pressure caused by drilling fluid invasion into the reservoir. Sensitivity analysis are conducted on the hydrate reservoir's response to drilling fluid density, temperature and formation permeability. Additionally, the wellbore collapse period for hydrate formations is predicted. The results show that invasion of drilling fluid into the hydrate formation causes a rapid rise in pore pressure around the wellbore. The decomposition of hydrate leads to a decrease in the mechanical properties of the formation, increasing the risk of wellbore collapse. With the increase of drilling fluid density and reservoir permeability, the decomposition of hydrate around the well accelerates. The period of wellbore collapse for the hydrate formation is 10.2 days under the basic case.

1. INTRODUCTION

Natural gas hydrates can be considered as the future hydrocarbon energy (Kvenvolden, 1993; Wood and Jung, 2008; Sloan and Koh, 2007). China's sea areas hold about 80 billion tons of oil equivalent in natural gas hydrate resources, with 74.4 billion tons in the South China Sea. This makes it a key source of clean and efficient oil and gas replacement for the country. Currently, several countries are engaged in natural gas hydrate extraction, using methods such as depressurization, thermal stimulation, and chemical inhibition(Xu and Li, 2015; Moridis et al, 2011). However, safe and reliable drilling technology is essential for the successful exploration and development of these resources.
A THM Model for CH4-CO2 Transport in Fractured Coal
Authors: Tian Jianwei , Gao Yanan
Published: January 2025

In the context of the global energy transition and the drive towards achieving net-zero carbon emissions, unconventional gas extraction methods have gained significant attention. This paper presents an advanced fully coupled thermo-hydro-mechanical (THM) model for enhancing methane (CH4) production and simultaneously storing carbon dioxide (CO2) in fractured coal seams. Our innovative approach integrates the complex interactions between thermal, hydraulic, and mechanical processes within the fracture network, addressing the dynamic evolution of matrix and fracture permeability ratios. By injecting CO2 into coal seams, methane is desorbed and produced more efficiently, while CO2 is securely stored within the fractures and pores of the coal matrix. The proposed model investigates the dual benefits of enhanced CH4 production and CO2 storage, offering a sustainable solution for energy production and greenhouse gas mitigation. Comprehensive simulations demonstrate the model's effectiveness in improving gas recovery rates and provide insights into the long-term stability of CO2 storage in geological formations. This study highlights the critical role of THM coupling in fracture networks and the dynamic permeability changes, ensuring a robust and efficient process for both gas extraction and CO2 sequestration, thereby contributing to the goals of the energy transition and net-zero carbon targets.

1. INTRODUCTION

The burgeoning energy demands of rapidly developing nations such as China and India have propelled coal seam gas (CSG), primarily methane (CH4), to the forefront as a significant energy resource. Simultaneously, escalating concerns over climate change have underscored the urgency for effective carbon dioxide (CO2) sequestration methods. Injecting CO2 into coal seams emerges as a promising strategy that not only facilitates long-term CO2 storage but also enhances CH4 recovery, offering a dual benefit of energy production and greenhouse gas mitigation (Gunter et al., 1998; Luo et al., 2013).

Despite the potential, the application of CO2 enhanced CH4 recovery and the simultaneous decarbonization faces substantial obstacles. Key among these are the complex multiphysics phenomena inherent in the process, including gas adsorption/desorption, diffusion, and the mechanical deformation of coal matrices (Bustin et al., 2016). The multiscale heterogeneity of coal seams—characterized by variations in porosity, permeability, and the presence of natural fractures—further complicates predictive modelling and optimization efforts. These challenges necessitate sophisticated modelling approaches to accurately simulate and manage the gas transport and storage mechanisms within coal seams.
2D Lineaments Extraction, Drainage Pattern Evaluation Using Digital Elevation Modelling and Tectonic Stress Magnitudes Analysis of Southern and Northern Potwar Deformed Zones (SPDZ & NPDZ), Pakistan
Authors: Fayyaz. Najwa
Published: January 2025

This research investigates the tectonic architecture and geomorphic evolution of the Southern and Northern Potwar Deformed Zones (SPDZ & NPDZ), leveraging cutting-edge geospatial and geophysical techniques. High-resolution Digital Elevation Models (DEMs) facilitated the extraction of 2D lineaments and drainage patterns, elucidating tectonic controls on fluvial morphology. The hydrological network was analyzed using the D8 method, while lineament extraction employed Hough transformation algorithms to enhance precision. Stream profile analyses quantified geomorphic indices, revealing marked contrasts in erosion and uplift rates between SPDZ and NPDZ. Advanced structural analyses utilized Rose and Mohr Diagrams to delineate fault orientations and compute tectonic stress magnitudes. Temporal structure maps, derived from seismic interpretations and two-way travel time (TWT) data, unveiled subsurface geometries, prominently featuring folded and thrust fault systems. A comprehensive correlation between drainage networks and tectonic lineaments highlighted their synergistic impact on regional landscape dynamics. This study confirms a compressive tectonic regime with localized strike-slip deformation and provides critical insights into the interplay of tectonic processes and geomorphic responses within the Potwar Plateau. These integrative methodologies present significant implications for structural analysis and hydrocarbon exploration in geologically intricate terrains.

1. INTRODUCTION

The Potwar Plateau is part of the Northwestern Himalayan Fold and Thrust Belt, located on the western border of the India-Eurasia collision zone. The Potwar Plateau's tectonic settings are impacted by the northward sinking of the Indian plate beneath the Eurasian plate. We utilized SRTM's Digital Elevation Models (90 m resolution version 3.0) The vectorization of flow directions enabled us to determine stream pathways. The retrieved drainage network included 112 streams that provided elevation and upstream area information based on their geographical positions (Ahmed, 2019).

The stream profile analysis assisted us in calculating the geomorphic indices and uplift rates for each stream under particular assumptions. The streams in NPDZ have higher steepness and concavity indices than the streams in SPPZ. The direction of lineaments and drainage patterns contributed to the mathematical deformation calculation. Seismic methods were utilized to investigate the Eocene successions, which are two conspicuous and significant reflectors (Najwa, et al., 2023). The seismic line's two-way travel time (TWT) was utilized to generate temporal structure maps. The Tectonic and geological map of Northern and Southern Potwar Deformed Zones is shown in Figure 1.

Published: January 2025

Hydraulic fracturing in coal measures strata encounters difficulties in the longitudinal penetration of fractures. To figure out which engineering parameters can hydraulic fractures penetrate through coal measure strata, a series of mechanical tests, in-situ stress measurement and true triaxial fracturing experiments were carried out. We found that the mechanical strength of mudstone is significantly higher than that of coal: in terms of the average values, the elastic modulus, uniaxial compressive strength, tensile strength, and fracture toughness of mudstone are 2.65 times, 1.47 times, 2.27 times, and 2.78 times those of coal, respectively. The higher of the fracturing fluid viscosity and injection rate, the easier for hydraulic fracture to penetrate. According to fracture penetration chart, a critical line was fitted. When injection rate > 6 m3/min & viscosity > 50 mPa·s or injection rate > 4 m3/min & viscosity > 150 mPa·s, hydraulic fracture can penetrate through coal measures strata.

1. INTRODUCTION

As an unconventional nature gas resource, coalbed methane (CBM) has the characteristics of clean, efficient, and large resource reserves. It is one of the important energy reserves. According to the prediction of CBM, the resource volume of CBM in the land area with a burial depth of 300-2000 m in China can reach 3.146×1012 m3(Chenglin et al., 2009). The exploration and development of CBM has great significance.

However, in western China, there exists a thin interbed reservoir with alternating mudstone and coal (Fig. 1). The production of CBM after fracturing is lower than expected due to inadequate communication in the vertical fracture direction. Previous fracturing experiments focus on hydraulic fractures propagate in coal, pay little attention to the research of hydraulic fracture penetration in coal measures strata.

Consequently, in this study, cores of coal and mudstone were employed to carry out macroscopic mechanical tests. The mechanical parameters of mudstone and coal were compared. The in-situ stress was restored through the Kaiser stress test. On this basis, True triaxial fracturing experiments were designed and conducted to explore the effects of injection rate and fracturing fluid viscosity on the fracture's cross-layer penetration capability. Eventually, a chart of fracture cross-layer penetration conditions was developed to provide a basis for on-site fracturing design.
Renewable Management Strategies for Geothermal Energy Reservoirs
Authors: Hamid Osman , Abdalrahman Eslam M.
Published: January 2025

The primary goal of this research is to develop and implement a robust management protocol for geothermal reservoirs that enhances energy extraction efficiency, prolongs operational life, and minimizes environmental impact.

The study employs a multifaceted approach starting with geoscientific exploration to pinpoint potential geothermal sites. Detailed feasibility studies follow, examining technical, economic, and environmental aspects to evaluate the viability of energy extraction. Drilling and well-testing are then carried out to acquire precise data on reservoir properties. This data feeds into advanced reservoir modeling using FEM (Finite Element Method), which simulates reservoir behavior to inform infrastructure development and operational strategies.

The application of this comprehensive strategy yielded significant improvements in reservoir output and longevity. The findings underscore the efficacy of FEM simulations in optimizing resource management and in mitigating environmental risks.

The innovative integration of geoscientific exploration, feasibility analysis, and FEM modeling represents a leap forward in geothermal reservoir management. The study's methodology sets a precedent for the application of sophisticated computational techniques in natural resource management.

Effective management of geothermal reservoirs can be achieved through an iterative process of exploration, data acquisition, and simulation-based planning. This approach not only secures the sustainable harnessing of geothermal energy but also ensures that extraction processes are economically viable and environmentally responsible. The customizable nature of the management protocol allows it to be adapted to a variety of geothermal contexts, promising wider applicability across different geologic settings.

Introduction

Geothermal energy represents a highly sustainable and renewable source of energy, generated from the Earth's internal heat. It is widely recognized for its capability to provide reliable, baseload power while producing minimal greenhouse gas emissions. The effective management of geothermal reservoirs is critical for ensuring their long-term productivity, maximizing the energy output, and mitigating potential environmental impacts.

Managing geothermal reservoirs involves several interconnected steps, beginning with exploration and site selection. Extensive geological, geochemical, and geophysical surveys are conducted to identify subsurface formations that exhibit high thermal potential. This initial phase is followed by detailed feasibility studies that assess both the economic and technical viability of the geothermal project. Environmental considerations are central to this analysis, as geothermal systems interact closely with local ecosystems and geological structures.
CO2 Injection and Sequestration Modelling in Deep Saline Aquifers Using Various Trapping Mechanisms
Authors: Fayyaz Najwa
Published: January 2025

Global warming threatens and deteriorates human life and the environment. It causes the rising sea level, increasing average global air and sea surface temperatures, and widespread snow and ice melting are well-known effects of global warming. The implementation and development of Carbon Capture and Storage (CCS) technology is highly recommended and progressive to reduce and minimize the amount of greenhouse gases entering the atmosphere. Therefore, carbon dioxide (CO2) sequestration is a technique to store CO2 in an underground formation. Successful CO2 storage in underground formations depends on many factors such as efficient sealing, no escaping from the storage, and minimum corrosion to injection tubing/casing. Therefore, proper planning involving thorough study and reaction kinetics of CO2 with the underground formation is indeed necessary for proper planning. This research project demonstrates serious trapping mechanisms of CO2 under deep saline aquifers for long-term storage of CO2. In this simulation model, CO2 is injected for 1 year (starting year, 01-01-2000) using CMG-GEM simulation software and then the fate of CO2 post-injection is modeled for the next 200 years (01-01-2200). The simulation results showed a notable effect on the sequestration of CO2 in the deep saline aquifers via various trapping mechanisms.

1. INTRODUCTION

Anthropogenic carbon dioxide's concentration in the climate has been rising at a concerning rate, during the past few decades. The IPCC proposes a 29,000 Gt carbon budget to limit global temperature increase to 2°C over preindustrial levels (Anderson et al., 2016). By 2100, 510Gt CO2 must be preserved globally, but only 300Mt (0.006%) is currently stored, with an efficiency rate of 40 Mt/yr. CO2 is a gas under atmospheric conditions but transforms into a supercritical fluid at pressures over 7.19 MPa and temperatures over 31.1°C, exhibiting both liquid and Gaseous properties It becomes conducive for subsurface storage, with its viscosity remaining similar to gases and density increasing like liquids, allowing more CO2 to be trapped in rock as shown in Figure 1. Carbon dioxide storage essentially involves injecting CO2 at high pressures into porous formations that are conducive for long-term storage over periods of the order 104 years. These reservoir depths allow the injected CO2 to remain in a supercritical state (Adewole and Sultan, 2019).
Motion Picture Paradise

Published: January 2025

Overlooked and underestimated in its contributions to motion picture history, the film and television industry in Florida has played a vital role in shaping American visual culture for over a century. From 1898, when the first war correspondents turned their cameras on the state to chronicle the onset of the Spanish American War, through the Ocala Drive-In’s unexpected role as the only theatre that contributed to the national box office in April 2020, Florida has persistently managed to remain in the limelight. The movies made in Florida are nearly as old as the industry itself, yet the state’s essential role as the “third coast” to the American motion picture industry has been mostly dismissed. The image of Florida as a place full of exotic beauty and adventure, set to the backdrop of swaying palms and sun-drenched beaches, has remained constant since the first film pioneers came to the state over one hundred years ago. Motion Picture Paradise tells the fascinating 125-year-long story of the contentious relationship between filmmakers and the Florida politicians who have inspired the rise, fall, and the many unexpected comebacks of one of the most unique production industries in the United States. This behind-the-scenes look into the countless films and television programs made in the state finally gives Florida its long-awaited starring role in American film history.
“Motion Pictures at a Great Saving!”
Authors: Morton David
Published: January 2025

Riding on the crest of the Florida land boom, local boosters attempted to create various studio cities across Central Florida and along the state’s West Coast during the 1920s and 1930s. Each of these fly-by-night ventures succumbed almost as quickly as they began due to misappropriation of funds, investor fraud, or lack of interest either by filmmakers or the local communities. To complicate matters further, Florida suffered a series of successive disasters caused by the 1926 Miami and 1928 Okeechobee hurricanes and the onset of the Great Depression. These developments inspired several questionable film promoters in the Tampa Bay area to pledge they could turn Florida’s West Coast into a “Second Los Angeles.” Through the efforts of CDMP director Trenton Collins, several film producers would make ill-fated attempts to establish studio operations along Tampa’s Davis and Weedon Islands as unprofessionalism and a lack of structural organization caused each of these ventures to eventually fail. After the failure of the Weedon Island studio venture, Florida once more fell back into position as an occasionally sought-after film location.
“The Business Can Kill You Anyway”
Authors: Morton David
Published: January 2025

This chapter tells how filmmaking at Silver Springs and Ocala State Park helped to inspire a state-wide ‘movie tourism’ industry. With the advent of the grindhouse and the B-movie film craze of the 1950s, Florida became a lucrative location, offering an affordable alternative for low-budget producers. The unexpected box-office success of The Creature from the Black Lagoon (1954) brought on a series of low-budget, independently produced horror and comedy films across the state. Orlando-based filmmaker R. John Hugh’s Empire Studios and Thomas Casey’s Shamrock Studios worked to turn Winter Park into a major film center several years before Walt Disney announced his plans for his “Florida Project.” At the same time another popular children’s entertainer, a Hungarian-born immigrant named Ivan Tors built his own studio in South Florida, while CBS and NBC each began to develop their own studio cities in the Greater Miami area. The popularity of Tors’s children’s television programming and films such as Flipper (1963) and Gentle Ben (1967-69), helped to cement Florida as a place of adventure and wonder for a new generation of small- and big-screen audiences.
“The Flip of a Switch”
Authors: Morton David
Published: January 2025

This chapter picks up as production activity winds down in Central Florida during the mid-2000s, and the center of gravity of the state-wide production industry shifts to South Florida. As the South Florida television industry experienced a resurgence after a series of tax incentives were initiated during the Jeb Bush and Charlie Crist administrations, Florida established an open policy of cooperation with the Florida Office of Film and Entertainment. These efforts toward cooperation came to a grinding halt when the Florida legislature denied requests to extend the incentives legislation after the funds were completely spent in 2016. Through interviews with film promoters who have advocated for greater government support and politicians who wish to allocate funds elsewhere, the chapter provides a clear of the inner workings of Florida’s entertainment economy. This chapter addresses only the major beats of the state’s decline in production following the 2016 expiration of tax incentives as Florida continues to come to terms with the rise of rival regional film centers across the South such as Atlanta, New Orleans, and Wilmington.

Published: January 2025

Western Belize was on the frontier of initial European contact in Central America and experienced the impacts of colonialism indirectly through immigration that brought new goods, foodways, and religious practices. This chapter provides an osteobiography of a young child buried at the site Cahal Pech, located in the upper Belize River Valley of western Belize during the Colonial period (AD 1520–1800). Combining skeletal analysis and mortuary analysis, radiocarbon dating, and stable isotope data about diet and mobility, this study provides the most concrete archaeological evidence for Colonial activity in the Belize River Valley date. While mortuary treatment was consistent with Classic Maya interments, the burial was placed in Cahal Pech centuries after the site’s Terminal Classic (~AD 850–900) abandonment. Strontium and sulfur geochemical data suggest immigration of the individual from the Petén to the west of the Belize River Valley. Evidence of Colonial period site use speaks to the strong connection the Maya had with their ancestors, with Cahal Pech perhaps representing a pilgrimage destination during this critical time of transition for lowland Maya communities.
Osteobiography of a Postclassic Maya Shaman/Priest
Authors: Cucina Andrea , Elizalde-Rodarte Sandra , Ortega-Muñoz Allan
Published: January 2025

This osteobiography deals with the human skeletal remains of a 30- to 34-year-old male individual (B. 18) who was born and died at San Miguelito, Cancun Island, along the East Coast of the Yucatan peninsula during the Postclassic (AD 1000–1540) Maya period. He was recovered inside residential Structure 3, together with eighteen more individuals. The overall taphonomic context and the skeletal analysis did not reveal anything out of the “norm” for Prehispanic commoners. Yet, an amazing set of paraphernalia associated to his body clearly indicated that this individual had specialized in ritual performances, like those of a shaman. Next to his seated body were twenty-four stingray spines, carved tubular animal bones (likely fan grips), two pointy bony bradawls and a ceramic vessel with representations of anthropomorphic faces on each side. The figure of the shaman in Prehispanic Maya iconography is associated with ritual bloodletting and the instruments commonly represented correspond to the ones found in this burial. Nonetheless, because of the context from which he was recovered, he likely used to be a lower-level priest or shaman, and not one of the highest hierarchies.

Published: January 2025

The multifaceted relationship between Monte Alban and Teotihuacan has been clearly established by archaeology. In recent research on the population of Monte Alban, oxygen isotope results identify possible migrants and their origins. One person had a foreign isotopic fingerprint, which coincides with the one reported for Teotihuacan. This osteobiography of the identified Teotihuacan immigrant is relevant to better understand the problem surrounding the relationship between the two cities. This is an adult man around 45 years old, who was buried in the family tomb of a domestic group of the minor nobility, in a house near the North Platform of Monte Alban, during the transition from the Terminal Formative to the Early Classic. The role of this individual as a member of the house is discussed, together with his relationship with other people in the group, like the young man next to him and an old woman in the northeast corner of the house, who possessed objects associated with Teotihuacan. Who was this man and why was he there? What can we say about his life history, health and diet? Why did he migrate to Monte Alban and at what stage of his life did he arrive? This chapter discusses these questions.

This study is the osteobiographic vision of Burial 3, a man of at least 50 years old dated to the 6th century AD, which was found in a prehispanic Maya platform in Caucel, Yucatan, during the 2017 field season. A miniature vessel associated with the individual in the burial was decorated with the image of the god of commerce, Ek Chuah. The analysis of occupational stress markers provided evidence for carrying, lifting, and paddling or rowing. Hyperdorsiflexion of the toes may also indicate activity-induced stress from habitual kneeling, such as when river canoeing. The evidence suggest that this man was a merchant who probably traveled long distances by water and land and may have dedicated his life to exchange goods.

Patent law serves as an effective instrument for protecting inventions and is particularly important for companies in the pharmaceutical sector. However, the law on the protection of trade secrets is closely interwoven with patent law. In practice, patents are therefore usually licensed along with the corresponding know-how. While § 24 PatG enables the compulsory licensing of patents under certain conditions, there is no similar provision in the law on the protection of trade secrets. This work examines the possibility and the need to implement a corresponding provision in the law on the protection of trade secrets in order to enable more effective measures in crisis situations. It focuses on the provisions of Directive (EU) 2016/943 and the constitutional requirements of the European Charter of Fundamental Rights.

The paper examines the influence of deviations in geometric parameters during excavation work and terrain conditions on the accuracy of determining the cross-sectional area in road construction. A detailed examination of the accuracy of the processes that determine the quality of shaping during excavation work in all their diversity is substantiated. Possible approaches to assessing the quality of shaping of objects are considered. It is proposed to use construction tolerances as limit deviations to assess the magnitude of deviations in the planned and altitude position of cross-sectional points of the roadbed. It is shown that the steepness of the slope and working marks can significantly affect the relative changes in the cross-sectional area. It is necessary to take into account the conditions of work at all intermediate stages. The obtained dependencies for determining the relative changes in the cross-sectional area take into account the influence of the working mark, slope steepness and hill slope. They can be used to standardize the requirements for the quality of shaping and initial information when designing slopes in different conditions, including when designing the roadbed of highways.

The paper presents a comparative analysis of the physical and mechanical properties of particle boards produced at periodic and continuous pressing plants. Some of the indicators for plates obtained by the periodic pressing method exceed similar indicators for plates obtained by the continuous method. The plates of the periodic pressing method have a higher density. With an equal density of 700 kg/m3, continuous pressing plates have higher bending strength and less swelling. The continuous pressing method makes it possible to obtain particle board of standard quality with a lower density, and therefore with a lower consumption of raw materials.

Published: January 2025

The forest resources of our country are distinguished not only by timber reserves, but also by the diversity of tree species. The characteristics of each breed determine its scope of use. Scots pine is distinguished by a wide distribution area, a large share in the total volume of resources, but it is also a widely and diversely used species. For successful planning of the use of wood, it is necessary to know its properties, which will differ slightly for different regions. It is important to identify the patterns of changes in the properties of wood that determine its industrial importance depending on various factors. In this work, the changes in the percentage of late pine wood from the southern taiga zone were studied in order to identify its change in the age and width of the annual layer. This can facilitate ways to assess the quality characteristics of wood.

Celem pracy było przedstawienie i porównanie plonowania i masy 1000 ziaren trzech odmian pszenicy ozimej (Symetria, SY Orofino, Argument) przeprowadzone w latach 2020-2022 na dwóch poziomach agrotechniki w Stacji Doświadczalnej Oceny Odmian w Karzniczce. Na podstawie analizy wyników przeprowadzonych badań stwierdzono, że uprawa pszenicy na poziomie agrotechniki a2 wpływa bardziej efektywnie na plon i masę 1000 ziaren niż uprawa na poziomie agrotechniki a1. Średni plon trzech odmian pszenicy ozimej w latach 2021-2022 na poletkach o intensywnym poziomie agrotechniki wynosił 9,02 t⸱ha-1 i był wyższy o 0,77 t⸱ha-1 w porównaniu z poziomem a1 (9,79 t⸱ha -1). W roku 2021 na obydwu poziomach agrotechniki najlepiej plonowała odmiana SY Orofino (a1 - 9,1 t⸱ha1 , a2 - 9,38t⸱ha-1 ). W roku 2022 na poziomie agrotechniki a1 najlepiej plonowała odmiana Argument (9,96 t⸱ha- ), a na poziomie a2 odmiana SY Orofino z plonem 10.71 t⸱ha-1 . Średnia wartość MTZ trzech odmianpszenicy ozimej w latach 2021-2022 na poletkach o intensywnym poziomie agrotechniki wynosiła 48,95 g i była wyższa o 2,65 g od masy średniej masy tych samych odmian pszenicy ozimej na poziomie a1(46,3 g). Najwyższą MTZ z trzech badanych odmian pszenicy ozimej na dwóch poziomach agrotechniki w roku 2021 osiągnęła odmiana Symetria (a1 – 45,8 g, a2 – 47,1 g), a w roku 2022 na odmiana Argument (a1 – 50,2 g, a2 – 53,3 g).

Introduction: The formation and development of the student as a future specialist is an urgent task of modern pedagogy. To achieve this goal, such a means of visualizing the skills and abilities acquired in the learning process as an excursion to the production facility is used. In the article the excursion is considered as pedagogical process, the characteristic pedagogical signs of excursion are considered and analyzed. In addition, there are those signs of the tour that distinguish it from traditional forms of learning. This allows us to consider the tour as an independent pedagogical process or as part of a system of pedagogical activities aimed at teaching and education. Aims of the research: To find out psychological - pedagogical approaches to improving students' interest in learning and self - education. Experimentally test the feasibility of this form of training, select and summarize its best features in the process of studying the disciplines of the professional cycle of training future specialists. Material and method: Analysis of scientific - methodical literature; analysis of educational and work programs, textbooks; observation of the educational process, interviews and questionnaires of students, analysis of reports and oral answers of students; pedagogical experiment; systematization and generalization of own pedagogical experience. The study was conducted among students studying for a Bachelor's degree in the specialty 141 “Electric Power, Electrical Engineering and Electromechanics” in a separate division of NULES of Ukraine “Nizhyn Agricultural Institute.
