Analysis of Coal Floor Fault Activation Inducing Water Inrush Using Microseismic Monitoring—A Case Study in Zhaogu No. 1 Coal Mine of Henan Province, China
Authors: Xin Chongwei , Jiang Fuxing , Zhai Changzhi , Chen Yan
Published: April 2023

Previously conducted studies have established that mining activities can activate faults, which will cause floor water inrush disasters and cause loss of personnel and property. In order to reduce the possibility of water inrush disasters in mining, it is particularly important to study the dynamic characteristics and rules of floor fault activation under the influence of mining. In this work, firstly, a microseismic monitoring system was established in the working face to analyze the changes of microseismic indexes before and after grouting. It was found that grouting can enhance the strength of a rock mass and play a role in sealing the water channel. Secondly, the quadratic kernel function of microseismic event energy was established. It was found that the accumulation degree of microseismic events and the region of high energy kernel density increased with the decrease of the distance between the working face and the left boundary of the “analysis region”. Combined with a microseismic event index and water inflow, the activation process of the floor fault was divided into five stages. Finally, the plastic failure region of surrounding rock under different excavation steps was analyzed by numerical simulation, and the characteristics of fault activation were further explained. A method of taking measures to prevent water inrush in the “sign stage of fault activation” was proposed.

Published: April 2023

The height of water-conducting fracture zone (HWCFZ) is one of the important technical parameters for water-preserved coal mining. The purpose of this paper is to acquire information about the height development characteristics of water-conducting fracture zone (WCFZ) in fully mechanized mining of shallow thick coal seam under water body in western mining area of China. The 91,105 fully mechanized mining face of Daheng coal mine under composite water body was taken as the research object, the development height, morphological characteristics, development and evolution process of WCFZ in working face mining were studied through underground up-hole water injection method by intervals, borehole TV and numerical simulation. The results show that the HWCFZ in 91,105 fully mechanized mining face is 52.7~53.6 m, and the fracture mining ratio is 12.55~12.76. The final development form is saddle-shaped with “large at both ends and small in the middle”. It is accurate and reliable to determine the development characteristics of overburden fractures and the HWCFZ by the field measurement of the combination of underground upward hole segmented water injection method and borehole TV. The development height of the water-conducting fracture zone obtained by numerical simulation is consistent with the field measured results. The development and evolution of the height of WCFZ presents four stages: “development–slow increase–sudden increase–stability”. When the WCFZ develops to a certain layer, the cracks generated by the weak strata in the fracture zone of overlying strata on the working face will automatically close with the advancement of the working face, resulting in “bridging phenomenon”, which inhibits the further development of the WCFZ. That is, the existence of soft rock with a certain thickness in overburden will become the key inhibiting layer for the development of WCFZ, effectively blocking the communication between water-conducting fracture and overlying aquifer. The research results are intended to provide guidance for the implementation of water preserving mining and ecological environment protection in ecologically fragile areas in western China.

Authors: Zhao Wenqi , Toh Moau Yong
Published: April 2023

Urban innovation has been highly regarded as a modern urban model that drives sustainable urban development by synthesizing knowledge innovation and technological innovation in industrial processes. As such, numerous studies have emerged to investigate the impact of the innovative city pilot policy (ICP), yet the impact of the ICP on industrial structure upgrading has not been explicitly studied. To address the research gap, this study utilizes the ICP in China as a quasi-natural experiment and investigates the impact of the ICP on industrial structure upgrading in Chinese cities. We apply a DID model estimation on a panel dataset of 284 Chinese prefecture-level cities from 2007 to 2019. The results indicate that the innovative city pilot policy greatly helps to upgrade the industrial structure in pilot cities, with the upgrading outcome particularly evident in large and non-natural resource-based cities. Mechanism analyses further reveal three channels via which the ICP promotes industrial structure upgrading, specifically by improving innovation capacity, boosting labor clustering, and lowering pollutant emissions. The results of this study carry significant policy implications for China in building a sustainable and modernized economic system and for other emerging nations in seeking economic transformation and industrial structure upgrading.

Published: April 2023

Traffic flow forecasting is a basic function of intelligent transportation systems, and the accuracy of prediction is of great significance for traffic management and urban planning. The main difficulty of traffic flow predictions is that there is complex underlying spatiotemporal dependence in traffic flow; thus, the existing spatiotemporal graph neural network (STGNN) models need to model both temporal dependence and spatial dependence. Graph neural networks (GNNs) are adopted to capture the spatial dependence in traffic flow, which can model the symmetric or asymmetric spatial relations between nodes in the traffic network. The transmission process of traffic features in GNNs is guided by the node-to-node relationship (e.g., adjacency or spatial distance) between nodes, ignoring the spatial dependence caused by local topological constraints in the road network. To further consider the influence of local topology on the spatial dependence of road networks, in this paper, we introduce Ollivier–Ricci curvature information between connected edges in the road network, which is based on optimal transport theory and makes comprehensive use of the neighborhood-to-neighborhood relationship to guide the transmission process of traffic features between nodes in STGNNs. Experiments on real-world traffic datasets show that the models with Ollivier–Ricci curvature information outperforms those based on only node-to-node relationships between nodes by ten percent on average in the RMSE metric. This study indicates that by utilizing complex topological features in road networks, spatial dependence can be captured more sufficiently, further improving the predictive ability of traffic forecasting models.

Envenomation caused by venomous animals may trigger significant local complications such as pain, edema, localized hemorrhage, and tissue necrosis, in addition to complications such as dermonecrosis, myonecrosis, and even amputations. This systematic review aims to evaluate scientific evidence on therapies used to target local effects caused by envenomation. The PubMed, MEDLINE, and LILACS databases were used to perform a literature search on the topic. The review was based on studies that cited procedures performed on local injuries following envenomation with the aim of being an adjuvant therapeutic strategy. The literature regarding local treatments used following envenomation reports the use of several alternative methods and/or therapies. The venomous animals found in the search were snakes (82.05%), insects (2.56%), spiders (2.56%), scorpions (2.56%), and others (jellyfish, centipede, sea urchin—10.26%). In regard to the treatments, the use of tourniquets, corticosteroids, antihistamines, and cryotherapy is questionable, as well as the use of plants and oils. Low-intensity lasers stand out as a possible therapeutic tool for these injuries. Local complications can progress to serious conditions and may result in physical disabilities and sequelae. This study compiled information on adjuvant therapeutic measures and underscores the importance of more robust scientific evidence for recommendations that act on local effects together with the antivenom.

Alfven-branch waves provide an efficient means for transporting energy into the auroral oval. Here, we report observations of these waves obtained by the Fengyun-3E (FY-3E)/ACMag instruments, which are designed to detect three-dimensional AC magnetic fields in the 0.05–25 Hz band. The observations suggest that broadband waves are a permanent feature of the auroral oval, although their amplitude and locations vary with the global state of the magnetosphere. We primarily focus on the data obtained from 10 July 2021 to 26 August 2021, during which a series of recurrent storms driven by solar wind corotating interaction regions (CIRs) occurred. Analysis of the observations shows that the auroral-oval waves grow in amplitude (1–3 orders of magnitude) and shift to lower latitude (∼10°) immediately following the decrease in the SYM-H index in each storm. Further investigation reveals the response of the auroral-oval waves has a time scale equal to or less than FY-3E’s effective revisiting time, which is about 45 min. The observations presented in this paper confirm that the FY-3E/ACMag instruments provide a high-resolution monitor of the auroral-oval waves and could further our understanding of auroral physics.

Published: April 2023

Artificial intelligence and machine learning have been increasingly used in the medical imaging field in the past few years. The evaluation of medical images is very subjective and complex, and therefore the application of artificial intelligence and deep learning methods to automatize the analysis process would be very beneficial. A lot of researchers have been applying these methods to image analysis diagnosis, developing software capable of assisting veterinary doctors or radiologists in their daily practice. This article details the main methodologies used to develop software applications on machine learning and how veterinarians with an interest in this field can benefit from such methodologies. The main goal of this study is to offer veterinary professionals a simple guide to enable them to understand the basics of artificial intelligence and machine learning and the concepts such as deep learning, convolutional neural networks, transfer learning, and the performance evaluation method. The language is adapted for medical technicians, and the work already published in this field is reviewed for application in the imaging diagnosis of different animal body systems: musculoskeletal, thoracic, nervous, and abdominal.

Authors: Scheveig Franck , Bucci Maria Pia
Published: April 2023

Several studies have reported motor deficiencies in children with dyslexia, in line with the cerebellar deficit theory. In the present study, we explored whether tests used by physiotherapists during clinical evaluation were able to report motor deficits in a group of fifty-six dyslexic children (mean age 10.9 ± 0.2 years old) compared to a group of thirty-eight non-dyslexic children (mean age 11.2 ± 0.4 years old). The occurrence of instability on an unstable support; spinal instability in the sagittal, frontal and horizontal plane; head-eye discoordination; and poor eye stability were clinically assessed in the two groups of children. All such measures were found to be significantly more frequent in dyslexic than in non-dyslexic children (p < 0.001, p < 0.05, p < 0.001 and p < 0.001, respectively, for occurrence of instability on an unstable support, spinal instability, head-eye discoordination and poor eye stability). These results, firstly, confirmed the poor motor control of dyslexic children, suggesting deficient cerebellar integration. Secondly, for the first time, we reported that simple tests that can be done by pediatricians and/or during a clinical routine evaluation could be useful to discriminate children with reading difficulties. The tests used in this study could be a reference for a first exploration of motor deficiencies in children with dyslexia that can be easily assessed by clinicians and/or physiotherapists.

Hydrological reaction to climate change anticipates water cycle alterations. To ensure long-term water availability and accessibility, it is essential to develop sustainable water management strategies and better hydrological models that can simulate peak flow. These efforts will aid in water resource planning, management, and climate change mitigation. This study develops and compares Sacramento, Australian Water Balance Model (AWBM), TANK, and SIMHYD conceptual models to simulate daily streamflow at Rajegaon station of the Pranhita subbasin in the Godavari basin of India. The study uses daily Indian Meteorological Department (IMD) gridded rainfall and temperature datasets. For 1987–2019, 70% of the models were calibrated and 30% validated. Pearson correlation (CC), Nash Sutcliffe efficiency (NSE), Root mean square error (RMSE), and coefficient of determination (CD) between the observed and simulated streamflow to evaluate model efficacy. The best conceptual (Sacramento) model selected to forecast future streamflow for the SSP126, SSP245, SSP370, and SSP585 scenarios for the near (2021–2040), middle (2041–2070), and far future (2071–2100) using EC-Earth3 data was resampled and bias-corrected using distribution mapping. In the far future, the SSP585 scenario had the most significant relative rainfall change (55.02%) and absolute rise in the annual mean temperature (3.29 °C). In the middle and far future, the 95th percentile of monthly streamflow in the wettest July is anticipated to rise 40.09% to 127.06% and 73.90% to 215.13%. SSP370 and SSP585 scenarios predicted the largest streamflow increases in all three time periods. In the near, middle, and far future, the SSP585 scenario projects yearly relative streamflow changes of 72.49%, 93.80%, and 150.76%. Overall, the findings emphasize the importance of considering the potential impacts of future scenarios on water resources to develop effective and sustainable water management practices.

Published: April 2023

To overcome the difficulty that existing hydrological models cannot accurately simulate hydrological processes with limited information in irrigated paddy areas in southern China, this paper presents a prediction model combining the Ensemble Empirical Mode Decomposition (EEMD) method and the Long Short-Term Memory (LSTM) network. Meteorological factors were set as the multivariate input to the model. Rainfall, regarded as the main variable affecting runoff, was decomposed and reconstructed into a combination of new series with stronger regularity by using the EEMD and K-means algorithm. The LSTM was used to explore the data laws and then to simulate and predict the runoff of the irrigated paddy areas. The Yangshudang (YSD) watershed of the Zhanghe Irrigation System (ZIS) in Hubei Province, China was taken as the study area. Compared with the other models, the results show that the EEMD-LSTM multivariate model had better simulation performance, with an NSE above 0.85. Among them, the R2, NSE, RMSE and RAE of the EEMD-LSTM(3) model were the best, and they were 0.85, 0.86, 1.106 and 0.35, respectively. The prediction accuracy of peak flows was better than other models, as well as the performance of runoff prediction in rainfall and nonrainfall events, while improving the NSE by 0.05, 0.24 and 0.24, respectively, compared with the EEMD-LSTM(1) model. Overall, the EEMD-LSTM multivariations model is suited for simulating and predicting the daily-scale rainfall–runoff process of irrigated paddy areas in southern China. It can provide technical support and help decision making for efficient utilization and management of water resources.

Published: April 2023

The coupling between optically active substances of algae particles and inorganic suspended solids of water makes the characteristics of reflection spectra of water complex and changeable. This makes modeling and inversion of polarization remote sensing in class II water difficult. In our study, considering the influence of the mixing ratio of algae particles and inorganic suspended solids, the sensor incidence angle, and the solar zenith angle on the polarization reflection spectrum, we analyzed the coupling characteristics of the polarized bidirectional reflectance of particulate matter through control experiments of mixed components of water particles in the laboratory. With Chaohu Lake in China as an example, the polarized reflectance coupling characteristics of water particles was investigated by the water-leaving radiation. The results showed that in the characteristic bands of 570, 675, and 705 nm, the degree of linear polarization (DOLP) was sensitive to the water-leaving radiation of the particles rather than to the reflectance. With the variation of observation angle, the reflection spectra were strongly interfered with by solar flare when the sensor zenith angle was close to 50° on the meridian plane with an azimuth angle of 180°, but DOLP was less affected, while also having a low correlation in the high concentration region. Combined with the coupling characteristics of particles at 675 and 705 nm, the model of DOLP ratio was established by partial least squares regression (PLSR) with a determination coefficient (R2) of 0.91, root mean square error (RMSE) 0.035, and a verification accuracy of 0.959. This shows that the model has better prediction ability for the coupling characteristics of water particles by the polarization reflection spectra and provides good support for mixed spectral unmixing of class II water.
Ant-Inspired Metaheuristic Algorithms for Combinatorial Optimization Problems in Water Resources Management
Authors: Bhavya Ravinder , Elango Lakshmanan
Published: April 2023

Ant-inspired metaheuristic algorithms known as ant colony optimization (ACO) offer an approach that has the ability to solve complex problems in both discrete and continuous domains. ACOs have gained significant attention in the field of water resources management, since many problems in this domain are non-linear, complex, challenging and also demand reliable solutions. The aim of this study is to critically review the applications of ACO algorithms specifically in the field of hydrology and hydrogeology, which include areas such as reservoir operations, water distribution systems, coastal aquifer management, long-term groundwater monitoring, hydraulic parameter estimation, and urban drainage and storm network design. Research articles, peer-reviewed journal papers and conference papers on ACO were critically analyzed to identify the arguments and research findings to delineate the scope for future research and to identify the drawbacks of ACO. Implementation of ACO variants is also discussed, as hybrid and modified ACO techniques prove to be more efficient over traditional ACO algorithms. These algorithms facilitate formulation of near-optimal solutions, and they also help improve cost efficiency. Although many studies are attempting to overcome the difficulties faced in the application of ACO, some parts of the mathematical analysis remain unsolved. It is also observed that despite its popularity, studies have not been successful in incorporating the uncertainty in ACOs and the problems of dimensionality, convergence and stability are yet to be resolved. Nevertheless, ACO is a potential area for further research as the studies on the applications of these techniques are few.

Published: April 2023

This paper applies the von Bertalanffy growth equation to study the age structure and growth characteristics of 210 Ptychobarbus dipogon collected in September 2019 in the middle and upper reaches of the Yarlung Zangbo River and employs FISAT II software to estimate the population characteristics’ parameters. Its aim is to provide a basis for the conservation of the population resources of the Ptychobarbus dipogon. In this study, the length of the catch ranged from 137 mm to 475 mm, the weight ranged from 44.04 g to 1142.80 g, the minimum age was 5 years, and the maximum age was 47 years. The body length–weight relationship was W(♀) = 4.1738 × 10−5L2.7687 (n = 86, R2 = 0.901); W(♂) = 2.7784 × 10−5L2.8434 (n = 100, R2 = 0.918). The growth equation was Lt(♀) = 505.000[1 − e−0.048(t−1.992)]; Lt(♂) = 452.254[1 − e−0.069(t−4.233)]; Wt(♀) = 1296.576[1 − e−0.048(t−1.992)]2.7687; Wt(♂) = 1001.872[1 − e−0.069(t−4.233)]2.8434. The inflection point ages of the female and male Ptychobarbus dipogon were 7.95 and 6.05, respectively. The exploitation rate of Ptychobarbus dipogon was 0.61, which exceeds the optimum exploitation rate of resources (0.57). The population resources are overfished. It is suggested to strengthen the conservation of Ptychobarbus dipogon population resources and the protection of native fish on the Qinghai–Tibet Plateau.

Published: April 2023

Coastal wetlands are natural complexes situated between terrestrial and marine ecosystems and are one of the most productive ecosystems in terms of global biomass production. However, under the influence of intensive human activity, global coastal wetlands have undergone rapid degradation. In this study, RS technology, landscape ecology, and object-oriented methods were used to interpret remote sensing images from different periods and analyze the dynamic changes in landscape patterns and their driving mechanisms in coastal wetlands in the Luoyangjiang River estuary from 1983 to 2021 by considering changes in the landscape pattern index. The results show that the patch areas of all the types of wetland landscapes in the Luoyangjiang River estuary changed, and the patch areas of mangroves and Spartina alterniflora increased. The patch density of the coastal wetlands increased significantly, the index of mangrove aggregation increased, and the index of separation decreased. From the perspective of the overall characteristic value of the landscape pattern, the landscape diversity index and the evenness index of the study area gradually increased, and the difference in the proportion of different types of landscape was reduced. Additionally, the patch number and patch diversity significantly increased, the maximum patch index and the spread index decreased, and the landscape separation index significantly increased. Rapid urbanization and the implementation of many ecological restoration projects were shown to be the main factors driving changes in the landscape indices of coastal wetlands in the Luoyangjiang River estuary. In the study period, rapid urbanization significantly reduced the area of coastal wetlands, and the implementation of ecological restoration projects increased the fragmentation, heterogeneity, and dispersion of wetland landscapes in the study area and decreased the aggregation of wetland landscapes. Moreover, the distribution of all the types of landscapes gradually became more uniform.

Authors: Liu Yuchen , Liu Jia , Li Chuanzhe , Liu Lusan , Wang Yu
Published: April 2023

This study established a WRF/WRF-Hydro coupled forecasting system for precipitation–runoff forecasting in the Daqing River basin in northern China. To fully enhance the forecasting skill of the coupled system, real-time updating was performed for both the WRF precipitation forecast and WRF-Hydro forecasted runoff. Three-dimensional variational (3Dvar) multi-source data assimilation was implemented using the WRF model by incorporating hourly weather radar reflectivity and conventional meteorological observations to improve the accuracy of the forecasted precipitation. A deep learning approach, i.e., long short-term memory (LSTM) networks, was adopted to improve the accuracy of the WRF-Hydro forecasted flow. The results showed that hourly data assimilation had a positive impact on the range and trends of the WRF precipitation forecasts. The quality of the WRF precipitation outputs had a significant impact on the performance of WRF-Hydro in forecasting the flow at the catchment outlet. With the runoff driven by precipitation forecasts being updated by 3Dvar data assimilation, the error of flood peak flow was decreased by 3.02–57.42%, the error of flood volume was decreased by 6.34–39.30%, and the Nash efficiency coefficient was increased by 0.15–0.52. The implementation of LSTM can effectively reduce the forecasting errors of the coupled system, particularly those of the time-to-peak and peak flow volumes.
Study on Characteristics of Pipeline Hydraulic Transportation of Coarse Particles Based on LBM-DEM Method
Authors: Wu Yuxi , Niu Weijing , Zhao Tingting , Li Zhiqiang
Published: April 2023

Pipeline hydraulic transportation is an important method for transporting solid materials. An LBM–DEM-based simulation method is established in the Visual Studio platform using the Fortran language, which can model the hydraulic transportation process of coarse particles in a pipeline. To verify the feasibility of this numerical simulation method, we also conduct pipeline hydraulic transportation experiments and find that the simulation results are consistent with the experimental results. This method is used to investigate the motion characteristics of coarse particles in horizontal pipelines under different conditions because of its advantages of clear physical meaning, ability to deal with complex boundary conditions, and suitability for parallel computing. The results show that the bedload motion is the main motion mode of coarse particles in horizontal pipelines. Changes in the pipeline flow velocity and particle diameter can cause some particles to saltate, and the critical pipeline flow velocity of saltation particles has a linear relationship with the particle diameter. During the process of coarse particles changing from the static state to stable state, the velocity curve of coarse particles gradually changes from “C” type to “S” type with the increase of particle diameter. Moreover, there is a linear relationship between the pipeline flow velocity and the stable velocity of coarse particles, while the particle diameter has no significant influence on the stable velocity. This study provides guidance for the development of pipeline hydraulic transportation technology of coarse particles.

Authors: Maddahi Mohammadreza , Rahimpour Majid
Published: April 2023

Bed irregularities of water bodies play a significant role in many hydraulic and river engineering experiments and models. Accurate measurement of river geomorphology requires great fieldwork effort. Optimizing the dataset size of measured points will reduce the time and costs involved. In this study, the geomorphology of a gravel bed river reach was measured using different spatial acquisition methods. Digital elevation models were created for each measurement method and the volumes of under/overestimation were calculated. The results show that the sampling methods had more effect on the accuracy of the interpolated geomorphology than the density of the measured points. By choosing an optimized sampling method, the measurement efforts decreased to less than 50%, with negligible errors of around 15 m3 and 10 m3 over and underestimation, respectively, in a water body area of around 2200 m2. These findings help to provide more accurate geomorphological data with less effort as inputs for experimental and numerical models to derive better results.
Changing Technological Development: Approaches, Methods, Problems and Prospects
Authors:   Institute of Economic of the Russian Academy of Sciences, Sukharev Oleg
Published: April 2023

Technological changes form the basis of modern economic development, however, in order to study their influence and features, as well as to develop control actions, it is necessary to adequately measure the level of technological effectiveness of the economy. The purpose of the study is to identify the limitations of existing approaches and methods for measuring technological development, indicating what prospects there are in terms of their improvement or the development of new ways to assess the level of manufacturability and emerging technologies. The methodology is based on the economic theory of technological development, statistical approaches to measuring the level of technological effectiveness of the economy, performance assessment, and comparative analysis is applied. The result is reduced to a reasonable position that the existing methods for measuring the level of manufacturability essentially do not reveal the true content of this concept, do not reflect the manufacturability of the economy. Thus, it is required to revise and introduce new accounting, measurement and statistical procedures covering the issues of technological development. The measuring apparatus for technological modes, the “knowledge economy” also requires perfection, which is proposed in this study. By modes, it is important to measure the distribution of policy instruments and the structure of technologies in each mode, for which accounting for specific types of technologies and the construction of technological maps can be used. The “knowledge economy”, which symbolizes a high level of technological development, needs to be measured in its purest form by the volume of sectors responsible for the creation, transfer, replication and application of advanced knowledge. Evaluation of productive jobs needs to be revised — from measuring wages in the workplace, as it is today, to measuring the level of its automation and intellectualization.

The article presents the results of clinical and laboratory studies of a new way of detoxifying the body with the external use of natural activated Uzbekistan glauconite ("Fatigrin") in patients with atopic dermatitis. Clinical, biochemical, and microbiological research methods have shown that in patients with atopic dermatitis, endogenous intoxication is accompanied by a disorder in the syndrome of colonization resistance of opportunistic microorganisms with a shift in skin pH to an alkaline environment, depending on the severity of the disease. The use of pelotherapy with glauconite mineral mask "Fatigrin" in the complex therapy of patients with atopic dermatitis contributes to a more pronounced decrease in the degree of endogenous intoxication of the body compared to standard therapy. The obtained data indicate the detoxifying effect of the mineral mask "Fatigrin" of external action, which can be recommended for the widespread introduction in dermatological practice.

Scientific novelty: it consists in the fact that works on the history of concepts and intellectual history, devoted to the thoughts and ideas of the French memoirists of the Napoleonic era about Eastern Europe, are rare. The author of the article proposes to increase scientific output in this direction.
Conclusions: in the process of writing the work, the idea of Eastern Europe had been considered in the memoirs of French military and politicians of the Napoleonic Wars and their input had been highlighted to the formation of the concept of «Eastern Europe».
French memoirists considered the partitions of the Polish-Lithuanian Commonwealth a mistake that allowed Russia to gain a foothold in Eastern Europe, and they believed Napoleon's plans to restore Polish statehood as a way to create a balance in European politics. The French invasion of Russia was called as important for the whole of Europe, and the characterization of Russians as «savages» and «barbarians» became widespread, French memoirists had been considered creating a kind of «barrier» in the form of a revived Poland to protect against the Russians.
Lithuania and Poland were perceived as the northeastern part of Europe, which separates European civilization from the huge Asian spaces and expansionist Russian Empire, whose continued westward expansion was seen as a threat to Europeans. Among the options for defining the cultural and civilization border between Europe and Asia, they proposed the former Russian capital Moscow or «Lithuanian-Russian» river Dnipro.

The article deals with metaphorical and metonymical modifications of the kernel components in homonymous phrases which due to the presence of certain cognitive links realize homophrasal relations and form homophrases.

The semantic composition of the constituent parts of A + N, Participle + N, N + N models which indicates the features included in the semantic volume of a significate forms stable binary units, in our case, – military homophrases. Homonymity is the process of secondary nomination of free phrases, the result of which is the homophrase, formed by metaphorization or metonymization of a free word combination that coincides with it in form, but differs in meaning and has all the characteristics of idiomaticity. The number of classification and implicational intra-verbal content connections is determined by the degree of semantic complexity of the original meaning of the phrase noun component, which in its turn affects the potentiality for the emergence of regular polysemy. The polysemantic noun-kernels in word-combinations become homonyms which is a precondition of forming homophrases. In the cognitive aspect the formation of military homophrases is observed by the type of cognitive links ''donor  recipient''. Donors are the nouns of free phrases with the semantics of the names of thematic groups. The recipients are military homophrases as the names of cognitive categories. The kernels of military homophrases when undergoing metaphorical modifications may be the donors for the formation of new phraseological meanings in the non-military phraseology .

The use of wood in buildings is an age-old craft, but recent proliferation of innovative wood-derived materials such as mass timber in commercial, institutional, industrial, and residential building signal the need for an education that expands upon these technological shifts. Academia and industry are proactively developing new curricula to address this challenge. This paper describes a wood design studio taught in combination with a seminar course run prior to the Fall 2020 launch of a new Master of Design in Integrated Wood Design at Fay Jones School of Architecture and Design at the University of Arkansas, located in a state that is 60 percent forested. This post-professional degree is part of a long-term investment to meet future needs of the wood industry in Arkansas and the nation. The studio–seminar clusters explored the nexus between mass timber and the built environment. These courses brought together teams of students from the departments of architecture, interior design, and civil engineering, and challenged them to examine the design potential of presenting wood and mass timber with the respect and legitimacy they deserve, to the extent of rivaling other materials like concrete or steel. This paper will first provide a discussion of the interdisciplinary collaboration, followed by the design method applied to mass timber. The pedagogy of the studio rests on collaborative interdisciplinary teaching and learning between faculty, faculty and students, and students. The design method applied in these courses does not follow a typical process, simply to allow students to remain focused on working with wood to inform the making of space. Rather than starting with the site, programming, massing, and so on, the process is reversed, beginning with the small—the detail connection—culminating into the large—the building.
Triple Standard: Addressing the Missing Middle in the Texas Triangle
Authors:   Texas A&M University, Tate James Michael
Published: April 2023

There’s an urban phenomenon happening in Texas. It’s called the Texas Triangle. Dallas-Fort Worth defines the top while Austin-San Antonio and Houston create the base. These major urban areas are connected by Interstate-45, Interstate 10, and Interstate 35. These cities, and other smaller ones, are experiencing significant transformational growth. Much of this is happening in outlying metro areas; causing once distinct cities to grow into one another. In the coming decades, the Triangle could become one megacity. To explore new futures of the Triangle, in 2019 I launched a multi-year design research investigation that explores alter¬natives to existing housing and land use models. The past six months was spent identifying different situations that exist in the periphery of major downtown areas. Outlining three prevailing spatial conditions is the primary focus of this paper. In January 2020, my design team started producing strategies that test density configuration, programmatic accommodation, and form generation relative to urban conditions of these places. Each of these investigations recognizes a missing middle scale of building and urban development. The current form of city-making will deplete resources in coming decades without producing a diverse mix of housing stock. Initial design work is mentioned in this paper, but remains schematic.
An Architecture of the Sea: Nationalizing the World’s Maritime Commons--Then and Now
Authors:   Smith College, Kim Elisa
Published: April 2023

Though May 12, 2019 marked the 10-year anniversary of the 2009 deadline for countries claiming sovereign territories along the ocean floor, many nations continue to file sovereign claims to extended seabed territories. In the largest land-grab since the colonial project, and in accordance with the provisions of article 76, paragraph 8 of the United Nations Convention on the Law of the Sea, eighty-five1 sovereign territorial claims to the ocean floor have been made for the purposes of resource extraction and exploitation. In an exhibition entitled “Nationalizing the World’s Maritime Commons, Then and Now: May 12, 2019 | May 12, 2019,” I produced an “Atlas of the Sea,” which renders visible these new oceanic territories in an effort to establish the space of the sea as a site for design, and to shift the frame of urbanism and territorialization to the space of the sea. In this paper, I expand upon the ideas put forth in the exhibition by making an argument for an architecture of the sea. By underscoring the discipline of architecture’s engagement with territory during the second half of the twentieth century, I argue that while a territorial approach to architecture is nothing new, it may serve as a precedent for developing an architecture of the sea. In particular, I argue that a territorial approach to— and an ethics of visibility for—designing the space of the sea is necessary in the face of a rapidly changing world order.

Beberapa kawasan banjir sebelumnya di daerah Kecamatan Driyorejo pernah teridentifikasi sebagai akibat dari penyempitan ruang pada daerah sempadan sungai yang terjadi diakibatkan dari pembangunan gudang dan ruko dari City Nine dan pembangunan perudi Desa Cangkir. Penyempitan ruang sungai juga terdapat pada kawasan Kali Afvoer sebagai kawasan peruntukan industri bagi Desa Sumput di Kecamatan Driyorejo. Penyempitan ruang pada sungai dan berkurangnya tanah serapan yang berada pada kawasan peruntukan industri di beberapa desa Kecamatan Driyorejo menyebabkan luapan air dari curah hujan yang tinggi tidak dapat terbendung. Penelitian ini bertujuan untuk mengetahui karakteristik kerentanan banjir di Kecamatan Driyorejo. Metode penelitian yang digunakan adalah teknik overlay union yang terdiri dari 4 parameter yakni curah hujan, penggunaan lahan, struktur tanah dan kemiring lereng. Metode pengumpulan data dilakukan dengan survei instansi, observasi dan dokumentasi. Hasil penelitian ini adalah wilayah Kecamatan Driyorejo masuk dalam kelas kerentanan yang rentan terhadap banjir. Hasil menunjukkan bahwa luasan wilayah dengan kerentanan yang rentan adalah sebesar 2427,60 Ha atau sekitar 47% dari dari luas keseluruhan wilayah Kecamatan Driyorejo. Hasil tersebut berasal dari beberapa indikator yaitu jumlah curah hujan 2020 mm/tahun yang termasuk dalam kategori curah hujan tinggi, bentuk penggunaan lahan sebagai besar merupakan pemukiman, sawah, lahan kosong, maupun semak belukar, jenis struktur tanah adalah alluvial kelabu dan grumusol yang mana termasuk tanah dengan kualitas liat yang cukup tinggi, dan nilai kemiringan lereng di wilayah Kecamatan Driyorejo berada pada kisaran 0-2 % dan 2-15 % yang merupakan tingkat kemiringan yang curam.
