Tool wear evolution and surface formation in milling various wood species
Authors: Keturakis Gintaras , Bendikiene Regita , Baltrusaitis Antanas
Published: March 2023

This study presents the results of tool wear and surface roughness of wood processed by plain milling. The tests were done on wood samples of pine and black alder grown in Lithuania in order to clarify time-related tool blunting and the aspects of surface formation. The samples were milled along the fiber in the experimental wood cutting stand at two different cutting and feed speeds. The roughness parameter (Rz) of the processed samples was measured in five sectors along and across the fiber using a contact profilometer. Registered values were analyzed by a Gaussian digital filter and evaluated according to relevant statistics seeking to minimize influence of wood anatomy. The obtained results helped to determine distinctions and variations of surface roughness, which strongly depend on the cutting path, rounding radius of the tool’s cutting edge, cutting, and feed speeds while milling pine and black alder.

Authors: Correa Mori Cynthia Massiel
Published: March 2023

La investigación tiene como objetivo general identificar los criterios que se ha empleado en el Distrito Fiscal de Lima Sur para aplicar la orden de prisión preventiva en los ilícitos penales de Peculado y Cohecho Pasivo Propio, años 2018-2020. Con este fin, se llevó a cabo una investigación de socio – jurídica, que abarcó el estudio programático de las medidas cautelares correspondientes a los años 2018, 2019 y 2020 y teniendo como unidad de análisis a jueces, fiscales y abogados del Distrito Fiscal de Lima -Sur. Se aplicó el muestreo intencional o no probabilístico y las técnicas para investigar como la encuesta, el análisis documental y entrevista, con una Guía de encuesta para los fiscales, jueces y abogados. Se identificó que existe una relación causal directamente proporcional entre el incremento de las causas por ilícitos penales cometidos por funcionarios públicos, en concreto los tipos penales de Peculado y Cohecho Pasivo Propio con la cantidad de prisiones preventivas concedidas en los mismos procesos en el periodo 2018 -2020. Se concluyó en que los criterios empleados en el Distrito Fiscal de Lima Sur para la aplicación del mandato de prisión preventiva corresponden a los preceptos del artículo 268 del Código Procesal Penal peruano.
Testing Convergence of Fiscal Policies in Regions of Turkey
Authors: Karaş Göksel , Karas Ebru
Published: March 2023

The presence of convergence in the fiscal policies implemented at the national level in order to eliminate regional inequalities is an indication that the resources are rationally distributed among the regions and the differences are decreasing. From this point of view, in this study, it is aimed to investigate the convergence of the fiscal policy implemented in the period of 2004:01-2020:12 in Turkey within the scope of the fiscal purpose of taxes. In the study, nonlinear convergence analysis was performed, but linear convergence analysis was used because the linearity hypothesis could not be rejected. According to the findings, there is an absolute convergence between the regions in the fiscal policy implemented in Turkey. However, in terms of regions, the first region is differentiated from other five regions, while the other regions are very close to each other. Regarding this, it may be possible to bring the first region and the other five regions closer to each other by reducing the difference with the arrangements to be made in taxation policies. The obtained findings offer important implications for policy makers.
Crecimiento urbano y su relación con el espacio público en la ciudad de Manizales, Colombia.
Authors: Ortega Sapuyes Juan Felipe , Giraldo Ospina Tania
Published: March 2023

Algunas ciudades presentan una evolución y expansión tanto urbana como poblacional a lo largo del tiempo, lo cual conlleva pensar en nuevas dinámicas de crecimiento urbano a partir de lo conocido, sin olvidar la importancia que implica el espacio público en la imagen y el desarrollo de una ciudad. El objetivo de la presente investigación es contrastar el crecimiento urbano de la ciudad de Manizales, Colombia por períodos desde su fundación hasta la actualidad a partir de la relación entre área de espacio público, número de habitantes y área urbanizada. A partir de un sistema de información geográfica (SIG) con el software libre QGIS se recopiló cartografía con el fin de procesarla en conjunto con fotografías y capas de datos para cada periodo, para analizar la forma urbana, los espacios públicos, la densidad urbana y el incremento poblacional. Se identificaron nueve períodos de tiempo desde 1848 hasta el 2021, en donde se evidenció un crecimiento urbano y de espacio público efectivo de manera constante hasta el período 1993-2008, junto con un descenso paulatino de la densidad poblacional registrada desde la fundación de la ciudad. Hasta el momento no se han encontrado estudios urbanos que contrasten el crecimiento poblacional y su relación con el espacio público de la ciudad de Manizales, impidiendo nuevas visiones de la evolución histórica desde su fecha de fundación hasta la actualidad.
Alcances de la reconversión territorial para la mitigación de factores condicionantes de pobreza urbana
Authors: Quintana Noriega María Carolina
Published: March 2023

El presente trabajo de investigación es un ejercicio prospectivo que identifica las lógicas de localización de los equipamientos urbanos dentro de la Zona Metropolitana del Valle de México (ZMVM) como metodología replicable para las ciudades mexicanas. Para ello, se parte de escenarios prospectivos, basados en la Estructura del Sistema Normativo de Equipamiento Urbano (ESNEU) de la Secretaría de Desarrollo Social (SEDESOL, 1999) y en destinos de usos de suelo comercial, habitacional, industrial y agropecuario, los cuales se integran conforme a variables de capital social y económico, propiedad pública o privada y densidad de población, reflejando áreas de población beneficiada y servida para determinar una lógica de localización metropolitana. Con ello, se analizan los posibles alcances de la reconversión territorial como instrumento de mitigación de ciertos factores socio-territoriales condicionantes de pobreza urbana. A su vez, se reconoce una deficiencia en el acceso a los servicios de educación y salud de las periferias urbanas, originada en el control del mercado y la propiedad del suelo, la especulación inmobiliaria y una lógica en favor del capital privado sobre el bienestar social de los grupos de menores ingresos. Es en este sentido que este trabajo presenta una modelación de las lógicas de localización de equipamientos e invita a revisar los criterios de planificación urbana vigentes, que operan sobre los fenómenos territoriales de la expansión de las ciudades mexicanas, con miras a la solución de estos problemas particulares de rezago social que inciden en las condiciones de pobreza urbana.

Published: March 2023

Este artigo estuda o funcionamento discursivo de memes que circulam na internet, pertencentes às famílias mêmicas “Expectativa x Realidade” e “Willy Wonka Irônico”. Com o suporte teórico e metodológico da Análise de Discurso (AD) pecheuxtiana, o objetivo é mostrar como se dá esse funcionamento discursivo, além dos efeitos de sentido produzidos por este tipo de materialidade imagética e de palavras, no ambiente digital. A partir dos gestos de análise empreendidos neste estudo, os resultados mostram que os memes não são somente um fenômeno massivo da era digital. Sob o prisma discursivo, são materialidades que, apoiadas pelo imbricamento entre textos verbais e não verbais, jogam com o equívoco da língua e abrem o leque de possibilidades para instauração de diferentes efeitos de sentido.
Interventions in spontaneous developed public spaces
Authors: Lleshi Blendi , Jashari Rineta , Fáczányi Zsuzsanna
Published: March 2023

Public green spaces are very important in the urban structure, both on environmental and social level. Renovation may be necessary, but the process must involve complexity.

The objective of this research is to define the main criteria of a successful renovation process, using two case studies - the Lucius-Burckhardt-Platz in Kassel, Germany, and the ‘Parku i lodrave’ in the city of Peja, Kosovo, where the recent intervention had rather negative effects. The paper considered aspects as community activity, key functions, visual elements, accessibility, safety, well-being and maintenance.

The transformation of these spontaneously developed, liveable spaces into renewed but abandoned parks was explained by the lack of correlation between the analysis of function, public needs, and the dominance of aesthetics.
Dynamic behavior of gravity segmental retaining walls
Authors: Alsirawan Rashad , Alnmr Ammar
Published: March 2023

This work aims to highlight gravity segmental retaining walls with their varied advantages. The paper investigates the dynamic behavior analysis of segmental retaining walls. The stability analysis is conducted on the basis of a pseudo-static Mononobe-Okabe theory that provides safety factors against sliding and overturning failure. The results demonstrate that the crucial safety factor of internal stability is the safety factor against overturning. Moreover, the positive wall inclination angle contributes to an improvement in the stability of the segmental retaining walls and the effect of the vertical seismic coefficient on the stability can be disregarding. Finally, a new equation is proposed for the elementary design of the segmental retaining walls.
Design and theoretical characterization of neomycin-guanine and neomycin-thymine using DFT methods
Authors: Hernández Castillo Juan Martín , Molina Brito Bertha , Soto Mercado Jorge Ramón , Francisco Santiago Pedro
Published: March 2023

Neomycin B is a drug of the bacteriologic category of aminoglycosides, built by four sugar rings joined with glycosidic bonds, that recently has attracted a lot of attention because its derivatives have shown anti-carcinogenic and antiviral properties, in addition to some gene therapy applications. Although some derivatives have been synthesized, there are no theoretical studies about them. In this work, we carried out DFT calculations to predict and study stable neomycin B derivatives, obtained by substituting its first ring by Thymine, as done in previous experiments, and for Guanine as a theoretical proposal. For the two nucleobases, we obtained stable quasi-degenerated structures, pointing out that there is equal probability to synthesize their isomers. Moreover, we calculated the electrostatic potential surface to elucidate the long-range interaction mechanism.

Authors: Özözen Danaci Miray , Bapoğlu Dümenci Sırma Seda
Published: March 2023

The study reported on here was conducted to examine the consistency of the views of children and teachers in predicting the multiple intelligence areas of children at the end of the education programme provided in an enriched class based on multiple intelligence practices in a pre-school education institution. Using the pre-test-education-post-test experimental method, we applied the relational pattern to investigate the relationship between the 2 variables. The sample group of this study consisted of 34 children aged 5 to 6 years, 17 in the experimental and 17 in the control group. As data collection tools, the TIMI Inventory developed by Teele (1992) and an application (colour-bead system) containing assessments of the children’s preferences were applied. The findings obtained in this study show that in 7 of the 17 children, the intelligence/skills area revealed by the evaluations of their preferences was similar to the results of the TIMI Inventory.

RELATION BETWEEN THE PRESSURE OF GASES AND THE HYDRATE FORMATION PROCESS: CONSEQUENCES FOR CO2/CH4 REPLACEMENT AND FOR STORAGE APPLICATIONS
Authors: Gambelli Alberto Maria , Serani Giovanni , Rossi Federico
Published: March 2023

The hypothesis pursued in this work deals with the influence that the local pressure of the reservoir could exert on the CO2/CH4 replacement and on the gas storage processes. To experimentally validate such hypothesis, the relation between initial pressure of the system and induction, formation, and dissociation time was found and described. Sixteen methane hydrates formation and dissociation tests were carried out in a lab-scale reactor. The tests were made consecutively and with the same gas-water mixture to avoid differences between the tests related to the memory effect. The main difference between experiments consisted in the initial pressure of the system, which ranged from 62.41 bar to 46.03 bar. The effect of varying the initial pressure was evaluated by considering its influence on the induction period and the time required for methane hydrates growth and dissociation.
NUMERICAL SIMULATION ON THE HEAT EXTRACTION OF ENHANCED GEOTHERMAL SYSTEM WITH DIFFERENT FRACTURE NETWORKS BY THERMAL-HYDRAULIC-MECHANICAL MODEL
Authors: Duan Xin-Yue , Huang Di , Sun Kang-Song , Lei Wen-Xian , Gong Liang , Zhu Chuan-Yong
Published: March 2023

Hot dry rock (HDR), as a kind of geothermal energy resource, has attracted much attention due to its wide distribution and huge reserves. This paper presents a numerical study on energy mining in the HDR by the enhanced geothermal system (EGS). The thermal-hydraulic-mechanical coupling model is employed in these simulations. The multi-field evolution process and the influence of the fracture parameters on the heat recovery performance of an EGS are analyzed comprehensively. The results show that the fractures parallel to the connecting line of the injection-production well can lead to an early thermal breakthrough, resulting in a thermal recovery performance decrease, while fractures perpendicular to the connecting line between the production and injection wells can enhance the production temperature of an EGS, when compared with the reservoir without fractures. The production temperature drop rate of the EGS with percolated fracture network is much quicker than that of the EGS with an isolated fracture network. Additionally, short fractures can lessen the potential for working fluid preferred flow channels to emerge; therefore, an EGS with short fractures may operate better than an EGS with lengthy fractures.
ASPIRING TO THE ROAD LESS TRAVELED: FACTORS INFLUENCING BLACK MALES' PURSUIT OF ENGINEERING GRADUATE DEGREES
Authors: Burt Brian A. , Stone Blayne D. , Porter Tiaira , Wallace Joshua D.
Published: March 2023

A growing body of research explores the experiences of students in graduate education and more-particularly, students of color pursuing advanced degrees. However, little research provides information about Black students' aspirations to pursue graduate education in science, technology, engineering, and mathematics (STEM). Even less is known about Black males' aspirations to pursue
graduate education in STEM. Knowing why Black males aspire to pursue graduate education would assist stakeholders (e.g., administrators, faculty, advisors, family members, and peers) in better supporting and motivating students while they are in graduate school, or earlier in their educational trajectories. This retrospective study of 50 Black males' aspirations for graduate school aimed to
better understand the factors that influenced their aspirations to pursue graduate degrees in engineering.
Four themes were most influential: (a) Black male students received messages implying that a bachelor's degree was insufficient, (b) earning a graduate degree in engineering was regarded as a sign of community influence and respect, (c) students' professorial career goals necessitated an
advanced degree, and (d) mothers functioned as support systems and role models for earning an advanced degree. Finally, we offer implications for future research and practice. These new findings about aspirations regarding graduate education will assist stakeholders in identifying critical moments and experiences necessary to encourage talented individuals to pursue advanced degrees in STEM fields.

Published: March 2023

This paper describes research into the poorly understood axial behaviour of piles driven in chalk. Comprehensive dynamic and monotonic axial testing on 27, mostly instrumented, piles undertaken for the ALPACA joint industry projects is reported and interpreted covering: diameters between 139 mm and 1·8 m; lengths from 3 to 18 m; different pile material types; tip and groundwater conditions; and ages after driving. The experiments show the factors that influence resistance most strongly are: (a) pile end conditions; (b) slenderness ratio and flexibility; (c) shaft material; (d) age after driving; (e) relative water table depth; and (f) whether loading is compressive or tensile. Varying the factors systematically identified a remarkable average long-term shaft resistance range from below 11 kPa to more than 200 kPa for piles driven at the same low- to medium-density chalk test site in Kent (UK). Dynamic and static analyses demonstrate that soil resistances to driving were generally well predicted by the Chalk ICP-18 short-term formulation. Considering the piles’ long-term behaviour, the Chalk ICP-18 approach over-predicted capacity, while the widely used CIRIA approach proved over-conservative for most cases. The research enabled the development of a revised ‘ALPACA-SNW’ long-term capacity assessment method that matches the test outcomes far more faithfully.
Optimising internal curing parameters for autonomous curing of normal-strength concrete
Authors: Atsbha Tesfaalem Gereziher , Zhutovsky Semion
Published: March 2023

Autogenous curing, also known as internal curing (IC), has revolutionised the way high-performance concrete (HPC) and high-strength concrete (HSC) are cured. IC improves the service life of concrete by lowering early-age cracking and enhancing durability. However, normal-strength concrete (NSC), the most commonly used type in the industry, is typically cured using conventional methods. Researchers are thus looking at ways to reproduce the positive results found in internally cured HSC/HPC in NSC. Studies have shown that IC is feasible in NSC despite its higher permeability, which results in loss of internal curing water (ICW). However, no comprehensive study has attempted to assess how the type, size and amount of IC agents affect the properties of NSC. The aim of this work was thus to optimise IC parameters for autonomous curing of NSC. The findings of this study support the notion that IC is possible in concrete with a high water/cement ratio and that, compared with lightweight aggregates (LWAs), superabsorbent polymers significantly impacted the durability properties of the NSC. Moreover, varying the size of the IC agent (LWA) had little effect on NSC properties, while increasing the amount of ICW considerably improved the durability properties.

A katonai műveletek hatása a környezetre
Authors: Padányi József
Published: March 2023

A 2022. február 24-én, Ukrajna ellen indított orosz háborús műveletek kapcsán érdemes áttekinteni azt, hogy a katonai erő műveletei, működése milyen hatással van az épített és természetes környezetre. A téma nem csak azért aktuális, mert a konfliktus ráirányította a figyelmet a háborús pusztításra Ukrajnában. A 2022. június 28–29-én tartott madridi NATO csúcstalálkozón – először a NATO történelmében – kiemelt jelentőségű biztonsági kockázatként azonosították az éghajlatváltozás okozta hatásokat, alapozva a 2021. június 14-én elfogadott Cselekvési Tervre.[1] Minden adat azt bizonyítja, hogy a háborús konfliktus – számos egyéb mellett – olyan hatásokkal jár, mely az éghajlatváltozást gyorsító következményeket eredményez. A továbbiakban az orosz agresszió kapcsán kialakult környezeti helyzet néhány kérdését tekintjük át – mind az épített, mind a természetes környezetre vonatkozóan – de utalunk korábbi katonai konfliktusok ilyen jellegű hatásaira is.[2] Teljességre nem tudunk és nem is akarunk törekedni, hiszen az információk töredékesek, sokszor egymásnak ellentmondóak. Emellett az sem vállalható fel a terjedelmi korlátok miatt, hogy a következmények minden elemét bemutassuk. Részletesebben foglalkozunk a háború okozta környezetszennyezéssel, a háború és a víz kapcsolatával, érintjük az infrastruktúra egyes elemeinek (kulturális javak, energetika, egészségügy, közlekedés) rombolását és annak következményeit.

Published: March 2023

The use of immune checkpoint inhibitors in malignant tumors improves patient outcomes. Because single-agent immune checkpoint blockade has a low objective response rate, it is meaningful to explore combined blockade of immune checkpoint receptors. We aimed to investigate the co-expression of TIM-3 with TIGIT or 2B4 on peripheral blood CD8+ T cells from patients with locally advanced nasopharyngeal carcinoma. The correlation between co-expression level and clinical characteristics and prognosis was studied to provide a basis for immunotherapy for nasopharyngeal carcinoma. Flow cytometry was used to detect TIM-3/TIGIT and TIM-3/2B4 co-expression on CD8+ T cells. The differences in co-expression between patients and healthy controls were analyzed. The correlation between co-expression of TIM-3/TIGIT or TIM-3/2B4 and the patient clinical characteristics and prognosis was examined. Also, the correlation between the TIM-3/TIGIT or 2B4 co-expression and other common inhibitory receptors was analyzed. We further validated our results using mRNA data from the Gene Expression Omnibus (GEO) database. TIM-3/TIGIT and TIM-3/2B4 co-expression was upregulated on peripheral blood CD8+ T cells from patients with nasopharyngeal carcinoma. They were both correlated with poor prognosis. There was a correlation between TIM-3/TIGIT co-expression and patient age and pathological stage, whereas TIM-3/2B4 co-expression correlated with age and sex. CD8+ T cells with elevated mRNA levels of TIM-3/TIGIT and TIM-3/2B4 also showed increased expression of multiple inhibitory receptors, indicating T cell exhaustion in locally advanced nasopharyngeal carcinoma. TIM-3/TIGIT or TIM-3/2B4 can be used as potential targets for combination immunotherapy in locally advanced nasopharyngeal carcinoma.

Authors: Gnanasekaran Vijayalakshmi , Perumal Vanamail , Periyasamy Mahendiran , Ramanathan Meena , De Britto Lourduraj
Published: March 2023

Introduction: The morbidity management and disability prevention (MMDP) strategy for elimination of lymphatic filariasis (ELF) focuses on alleviating the sufferings of about 36 million filariasis patients living in 49 endemic countries. At present, available quality of life questionnaires are not adequate to address the stigma and stress of filarial lymphoedema (FLE) patients. Therefore, a comprehensive and a robust stigma and stress assessment tool needs to be developed.
Methods: We developed 49 item SARI-FLE-Version-2 questionnaire for stigma assessment and 20 item PSS-FLE-Version-2 questionnaire for stress assessment and tested it among different grades of FLE patients. We followed the Likert scale scoring system and conducted a statistical analysis using SPSS IBM version 25.0.
Results: Of the 80 lymphatic filariasis (LF) patients assessed, 35.0%, 42.5%, and 22.5% had grades 2, 3, and 4 LE of the lower extremity, respectively. The developed stigma tool had an excellent internal consistency, as indicated by high Cronbach alpha values for all six domains. There was a significant correlation (p < 0.05) between different stigma domains. In three domains (cognitive function, social stigma, and experienced stigma), the mean stigma scores were significantly higher for the grade 4 patients compared to grade 2 patients (p < 0.02).
Conclusion: Stigma and stress assessment tools in the form of 49 item SARI-FLE-Version-2 and 20 item PSS-FLE-Version-2 questionnaires are reliable in quantifying the stigma and stress of LF patients. There is a scope to incorporate these tools in the MMD
On Fixed-Accuracy Confidence Intervals for the Parameters of Lindley Distribution and Its Extensions
Authors: Bapat Sudeep , Joshi Neeraj , Shukla Ashish
Published: March 2023

The purpose of the present paper is to deal with sequential estimation of the parameter θ in a Lindley distribution. A fixed-accuracy confidence interval for θ with a preassigned confidence coefficient is developed. It is established that, no fixed sample size procedure can solve the estimation problem and hence a purely sequential methodology is proposed to deal with the situation. The first-order asymptotic efficiency and consistency properties associated with our purely sequential strategy are derived. Similar estimation strategies are also outlined for a few other extensions of the Lindley distribution. Extensive simulation analysis is carried out to validate the theoretical findings. We also provide a real data example, where we estimate the parameter related to the “initial mass function" for a particular cluster of stars.

In the conditions of a military invasion of Ukraine, the discourse of national security and the place of our state in the system of international relations is expected to be actualized. This trend originates from such a global characteristic of the modern world as the spread of risk situation. From our point of view, the development of democracy and civil society is an important factor in ensuring the internal and external security of our country. One of the important prerequisites for effective security of Ukraine is the level of involvement of civil society into this process. Hence the need for a theoretical analysis of the discourse of civil society and democracy, reconstruction of the main concepts and concepts used in it. Otherwise, if this discourse is used uncritically, there is a danger that terms and words begin to obscure reality from our view. The works of domestic and foreign authors were used to study the problem posed in the article. The research is based on the principles of such methodological approaches as critical, interdisciplinary, systemic and comparative analysis, as well as on general scientific principles of objectivity and historicism. A developed civil society provides for the articulation of public interests, within the horizon of which the realization of private interests takes place. This situation requires the replacement of «patronage politics» by «politics of real affairs». From the point of view of the study of mechanisms for ensuring democratic security, this means that it is possible to talk about it within the functioning of the public space. Democratic security is possible if citizens are active.

The study aimed to serologically detect the prevalence of Sarcocystis infection in buffaloes using the indirect enzyme-linked immunosorbent assay (ELISA) for the first time in Iraq. An overall 184 buffaloes of different ages and sexes were selected randomly from the regions of Wasit province (Iraq) from March to June (2022), and subjected to draining of venous blood under aseptic conditions. After centrifugation, the obtained sera were examined by indirect ELISA. Totally, 33.15% of study animals were positive for IgG antibodies. According to their concentrations, the ODs level showed a significant increase (P<0.0186) in mild infection (63.93%) when compared to moderate (27.87%) and strong (8.2%) infections. Subsequently, values of mild, moderate, and strong infections were 0.330 ± 0.01, 0.554 ± 0.019 and 0.912 ± 0.031 nm, respectively. Regarding age and sex factors, significantly higher positivity (P<0.0469) was shown in buffaloes aged >10 years old (57.89%); while the lowest was seen in those <1 year (13.64%). Subsequently, older buffaloes appeared significantly (P<0.0192) at higher risk (2.1685) when compared to other age groups. Females recorded an obvious increase (P<0.05) in positivity (35.95%) and risk (1.8569) in comparison with males; 19.35% and 0.5385, respectively. The results indicate that ELISA is of great value in the diagnosis of sarcocystosis.

Измена как феномен супружеских отношений
Authors: Васина Инга Дмитриевна
Published: March 2023

Статья посвящена актуальной проблеме семейной психологии — проблеме супружеской неверности. На теоретической основе в ней рассматриваются основные подходы в историческом и современном понимании феномена супружеской измены. Констатируется, что проведенные исследования подтверждают, что больше половины россиян изменяют своим половым партнерам.

Раскрывается понятие супружеской измены, обозначаются ее мотивы и структура. Рассматривается феномен психологической готовности к супружеской измене. Показывается, что супружеская измена может быть как однократной, так и систематической. Приводятся основные мотивы измены, имеющие индивидуальные особенности и различия. Указывается, что ученые склоняются к теории, согласно которой в действительности к измене склонны представители обоих полов.

Опираясь на статистические данные и привлекая воззрения отечественных авторов на проблему, автор делает вывод о разрушительности супружеской измены для психологического благополучия и безопасности человека. Измена как глубокая психологическая травма приводит к неблагоприятным для психики последствиям (алкоголизм, депрессия, агрессивность, суицидальные наклонности и др.).
The 2022 Mw 6.7 Menyuan Earthquake on the Northeastern Margin of the Tibetan Plateau, China: Complex Surface Ruptures and Large Slip
Authors: Niu Pengfei , Han Zhujun , Li Kechang , Lv Lixing , Guo Peng
Published: March 2023

On 8 January 2022, the Mw 6.7 Menyuan earthquake occurred near the stepover of the Lenglongling (LLLF) and Tuolaishan (TLSF) faults of the Qilian–Haiyuan fault zone in the middle of the northeastern Tibetan plateau. Field investigations and unmanned aerial vehicle-based photogrammetry revealed that the earthquake generated five surface rupture zones with different strikes and kinematic properties. Two large rupture zones, R1 (∼22.8 km long) and R2 (∼3.9 km long), occurred along the northern branch of the western LLLF and the eastern segment of TLSF, respectively, and featured left-lateral strike slips. Among the three small rupture zones, the left-lateral strike-slip-type R3 (0.6 km long) was located in the extension direction of R2, whereas the thrust-type R4 (∼3.3 km long) and R5 (∼1.1 km long) zones were located north of the central section of R1. These complex multifault ruptures were caused mainly by the rupture of strike-slip faults on both sides of the stepover structure. A small amount of compressive shortening strain was released during the earthquake due to regional oblique compression. The total length of the rupture zone was ∼31.7 km; the maximum left-lateral and vertical offsets were 3.5 ± 0.3 and 0.47 ± 0.04 m, respectively. Compared with the relationship observed between coseismic slips and magnitudes in historical and modern earthquakes in western China, the 2022 Menyuan earthquake produced a large coseismic slip in relation to its magnitude. The distribution characteristics of the aftershock belts and their relationship with rupture zones showed that the seismogenic fault of the earthquake was nearly east–west-striking TLSF, which may have triggered the rupture of the northern branch of the western LLLF. In addition, only a small segment of TLSF was ruptured, indicating that the accumulated strain could not be released completely during the earthquake and that this remains the most likely area for the occurrence of large earthquakes in the future.
Thermal lattice BGK models for fluid dynamics
Authors:   , Huang Jian , Feng Da Hsuan
Published: March 2023

As an alternative in modeling fluid dynamics, the Lattice Boltzmann method has attracted considerable attention. In this thesis, we shall present a general form of thermal Lattice BGK. This form can handle large differences in density, temperature, and high Mach number. This generalized method can easily model gases with different adiabatic index values. The numerical transport coefficients of this model are estimated both theoretically and numerically. Their dependency on the sizes of integration steps in time and space, and on the flow velocity and temperature, are studied and compared with other established CFD methods. This study shows that the numerical viscosity of the Lattice Boltzmann method depends linearly on the space interval, and on the flow velocity as well for supersonic flow. This indicates this method's limitation in modeling high Reynolds number compressible thermal flow. On the other hand, the Lattice Boltzmann method shows promise in modeling micro-flows, i.e., gas flows in micron-sized devices. A two-dimensional code has been developed based on the conventional thermal lattice BGK model, with some modifications and extensions for micro-flows and wall-fluid interactions. Pressure-driven micro-channel flow has been simulated. Results are compared with experiments and simulations using other methods, such as a spectral element code using slip boundary condition with Navier-Stokes equations and a Direct Simulation Monte Carlo (DSMC) method.
Adult hepatoblastoma: making the challenging distinction from hepatocellular carcinoma
Authors: Pagarigan Allison Kaye L. , Mendoza Paulo Giovanni L.
Published: March 2023

Hepatoblastoma is an exceptionally rare malignancy in adults with just over 70 non-pediatric cases reported in literature. Recounted is a case of a 49-year-old female who presented with acute right upper quadrant abdominal pain, elevated serum alpha fetoprotein and a large liver mass on imaging. Hepatectomy was performed under clinical suspicion of hepatocellular carcinoma. Immunomorphologic characteristics of the tumor proved consistent with hepatoblastoma of mixed epithelial and mesenchymal type. Hepatocellular carcinoma remains to be the primary differential diagnosis for adult hepatoblastoma, however, distinguishing between these two neoplasms requires close histomorphologic assessment and immunohistochemical profiling as clinical, radiologic and gross pathologic findings typically overlap. Making this distinction is highly crucial in the timely initiation of surgical and chemotherapeutic interventions for this inherently aggressive and rapidly fatal disease.
