Method based on a multi-image feature fusion model for detecting weld defects in time-of-flight diffraction images
Authors: Yue Kun , Jiang Hongquan , Zhi Zelin , Yang Deyan , Cheng Zhixiang
Published: October 2024

The time-of-flight diffraction (TOFD) technology is widely used in weld defect inspection and the utilisation of TOFD images in automatic defect recognition is attracting interest from enterprises. However, the extant artificial intelligence (AI)-based object detection methods have
limitations: they use only a single image, the ability to extract defect features is weak and they are easily affected by interference fringes. These limitations result in high miss and false detection rates. In this study, a weld defect object detection method based on a multi-image feature
fusion model (MIFFM) is proposed. The original TOFD input image was preprocessed using adaptive Gaussian filtering (AGF) and anisotropic filtering (specifically, Perona-Malik (P-M) filtering) to remove noise and enhance the defect features in the image. Subsequently, the AGF preprocessed,
P-M filtering preprocessed and original TOFD images were stacked and used as input images. To enhance the detection performance, the you only look once X (YOLOX) bidirectional feature fusion network combined with the non-monotonic dynamic Scylla-intersection over union (SIoU) loss function
was constructed. Finally, the feasibility of the proposed method was verified using the TOFD image of a large-pressure spherical tank weld. The proposed method achieved a mean average precision (mAP) of 78.05%, which is higher than YOLOX by 4.59%.
Loosening detection method for hexagonal screws based on error compensation and deep learning
Authors: Li Yang , Luo Pengzhan , Zhou Yang
Published: October 2024

Screws are extensively utilised across various domains. However, the problem of screw loosening not only impacts the stability and safety of engineering structures but also poses the risk of severe accidents and losses. The hollow design of hexagonal screw heads limits the effectiveness
of conventional methods for detecting screw loosening. Additionally, traditional visual detection methods are influenced by the surrounding environment, affecting detection accuracy. To tackle these challenges, this study introduces a novel approach based on deep learning for detecting loosened
hexagonal screws. This method primarily relies on the you only look once version 8 (YOLOv8) algorithm to accurately detect the coordinates of the four key points of the hexagonal screw. By applying geometric imaging theory, equations are derived for calculating the loosening angle and length
of hexagonal screws. By utilising these equations along with bolt parameters, the degree of loosening is determined. Furthermore, photos captured in low-light environments are enhanced using an improved automatic colour enhancement (ACE) algorithm, which saturates image colours to improve
environmental adaptability. This enhancement facilitates better recognition of hexagonal screws even in dark environments. Four colour enhancement methods are also evaluated based on four criteria. Moreover, by employing a back-propagation (BP) neural network for error compensation, the proposed
method brings predicted values closer to actual values. The experimental results demonstrate an angular identification error of less than 1° and a length identification error of less than 1 mm for loose hexagonal screws.

Authors: Cui Ranting , Wei Chaojun , Zhang Keping , Wu Yuning , Zhu Xuan
Published: October 2024

Thermographic techniques are widely used to characterise material damage, porosity and moisture in structures. Due to the thermographic signal reconstruction (TSR) technique, active thermography has made significant progress. In this study, the TSR technique was applied to identify
a rubber layer that mimics an internal defect, which is attached to the back of the steel plate, after a 1.0 min thermal stimulation. The peaks of the first and second derivative logarithmic curves correspond to the important time point revealing the position of the attached flaw. Furthermore,
a new post-processing technique for infrared thermographic data was proposed by exploiting polynomial orders of the fitting curves to produce a synthetic image, which can highlight the flaw with distinctive contrast. Finally, the upgraded TSR technique was applied to image a natural shelling
defect in a rail sample with an excellent contrast.
Coda Envelope Moment Magnitudes and Source Scaling for Southeastern Canada
Authors: Bent Allison L. , Mayeda Kevin , Roman-Nieves Jorge I. , Barno Justin
Published: October 2024

Although moment magnitude is the preferred magnitude scale for earthquake hazard assessment, it has been traditionally difficult to calculate for small earthquakes using methods such as moment tensor inversion that rely on long-period data. The coda envelope moment magnitude method, which relies on regional calibrations using ground-truth data, has emerged as a viable and stable option. In this study, we undertake a calibration of the region of southern Quebec and eastern Ontario containing three active seismic zones. The calibration enabled us to reduce the threshold for moment magnitude calculation from ∼3.5 to 1.5. This will lead to improved input to the seismic hazard models and a more uniform catalog. It simultaneously reduces the need for magnitude conversions while providing a larger data set for improving the conversion relations. The low attenuation and high apparent stresses of this region led to revisions of the coda calibration tool because some assumptions regarding the range of allowable values for parameters such as window length and stress were not valid for this region. Apparent stresses calculated in this study allow for reliable comparisons to other regions and for improved scaling relations. We see high stresses compared to other regions and evidence for self-similarity.
Teachers’ Literary Work for Children as a Tool for (Self-)Creation in Professional Development
Authors: Kupiec Monika , Twardosz Natalia
Published: October 2024

The preschool teacher’s own literary text for children of a preschool teacher based on her professional experience, published in book form, is a special tool – the impact on the child and the development of the teacher. The main goal of the article was to reach the determinants of the teacher’s motivation for literary activity for children. An individual case study using a literary text and an interview with its author was used. The research technique used is the content analysis of the interview with the author and the analysis of her literary text. The analysis draws on categories related to one of the perspectives of existence in biography – the sensitive narrator. In the text, the teacher perpetuated the needs of a real child. The genesis of the author’s book lies in the therapeutic impact of the teacher on the child and the impact of the text itself. The process of creating a literary text for children combined the teacher’s awareness of her own ability to influence who she is and became a tool for her own development. The preschool teacher’s own book for children is a tool of (self-)creation – a story about the child and herself.

Generation Z and the Choice of Authority
Authors: Jagielska Katarzyna
Published: October 2024

The article presents the results of research conducted in 2022 on Generation Z’s choice of authority. The introduction defines authority. Attention has been drawn to the fact that authority means a positive evaluation, recognition of someone as a person worthy to emulate, a role model, and the attribution of exceptional qualities to that person. The dynamic nature of the concept was also taken into account. Authority is an idea that changes over time and is determined by various factors, including the socio-cultural context. The research aimed at answering the question of who are authority figures for Generation Z, what qualities they possess and what values they should follow. The study was conducted in a quantitative paradigm, using a survey method and a questionnaire technique. The tool was a survey questionnaire. A total of 258 individuals took part in the study. The results of the survey indicate that parents and family members enjoy the greatest authority among Generation Z. They are followed by academic teachers, literary characters and well-known public figures.
Analysis of the Determinants of Seniors’ Suicidal Behavior – Towards Gerontosuicidology
Authors: Kania Sławomir
Published: October 2024

The increasing scale of suicidal behavior in the population poses a significant challenge to public health activities. Seniors, i.e. people over 60 years of age, and people of pre-retirement age constitute a higher risk group, which is visible in the number of suicide attacks and completed suicides. Comparative analyzes between individual age cohorts allow us to identify this age group as having the highest rate of attacks in relation to suicide attempts. The cognitive and theoretical goal is to learn about the determinants of seniors’ suicidal behavior. The practical and implementation goal is to develop recommendations for preventing seniors’ suicidal behavior. The main research problem is the following question: What are the determinants of seniors’ suicidal behavior? The desk research method was used. Using the typology of suicides presented by Durkheim, an attempt was made to analyze age-specific factors increasing the risk of suicide attacks. Due to the above, it is postulated to combine gerontological and suicidological knowledge into a gerontosuicidological perspective. Analyzes from this perspective will allow researchers to pay more attention to the problems of the suicidological crisis in the analyzed age cohort.
Peer Violence at School in the Perception of Teachers, Parents and Students
Authors: Sitarczyk Małgorzata , Dudziak Arkadiusz
Published: October 2024

The study attempts to assess the intensity of various forms of peer violence in the school environment. The research allows for a broader exploration of the phenomenon of violence and the identification of most common forms of violence, places where it occurs, the competences to deal with the problem and the specifics of students’ search for social support. The analysis of the research results shows the perspectives of parents, teachers and students on the awareness of the occurrence of indirect or direct aggressive behaviours, proving insight into the extent to which these three groups communicate with each other. The data obtained allow to answer the question whether this problem is noticed to a similar extent by parents, teachers and students. The results of own research showed many differences between teachers, parents and students in the awareness of the occurrence of peer violence, which indicates the need to consider the role of the adult-child relationship in the effectiveness of preventive interventions. In addition, in the discussion were proposed forms of violence prevention and the possibility of seeking information and psychological support for both students and adults.
Relationship Quality of Pregnant and Non-pregnant Women with and without Children
Authors: Banaszkiewicz Paulina , Górnik-Horn Karolina
Published: October 2024

The study aimed to determine differences in selected parameters of women’s relationship quality depending on whether they already have children with their current partner and whether they are currently pregnant. The study included overall relationship satisfaction, attachment anxiety and avoidance, and jealousy. The following scales were used: the Couple Satisfaction Index CSI-32, the Experience in Close Relationships – Revised, and the Multidimensional Jealousy Scale. The participants were 274 non-pregnant women and 105 pregnant women who were in a romantic relationship at the time of the study. The analyses showed that relationship satisfaction was higher among pregnant women. In this group, lower attachment anxiety and attachment avoidance, as well as weaker cognitive jealousy were also observed. Overall relationship satisfaction was lower in the group of women who had children, although when considering pregnancy, it was found that pregnant women showed the same level of relationship satisfaction regardless of whether or not they already had offspring. The research largely confirmed the higher relationship quality among pregnant women and partially lower relationship quality among women with children. However, the differences in terms of jealousy turned out to be inconsistent with the assumptions. The study’s conclusions were discussed in relation to the existing literature.

Published: October 2024

Odontometric measurements, are carried out for determination of space discrepancies in the dental arches. It is observed in orthodontic circles that a maximum number of cases of malocclusion appear during mixed dentition stage, which has long time period of time i.e from the 6 to 12 years. Space analysis in mixed dentition is an important aspect in orthodontic diagnosis and treatment planning.

: The present study was done to assess and compare the applicability of Melgaco's linear regression equation for mixed dentition analysis in the population of Panchkula district of Haryana state in North India.

Study was conducted on 200 patients who attended the OPD of department of Orthodontics & Dentofacial Orthopedics, Swami Devi Dyal Hospital and Dental College, Barwala, Panchkula, Haryana, in order to evaluate applicability of Melgaco’s mixed dentition analysis. A digital vernier caliper (0-150mm) SL 1112 INSIZE CO. Ltd with resolution 0.01 was used.

On comparing the values of our present study with the values derived from the Melgaco’s Brazilian population. The p value was ≤ 0.001 in males, females and overall sampled population which is considered to be statistically very highly significant when measurements of our study were compared with those for Melgaco’s Brazillian subjects.

The regression equation given by Melgaco’s et. al. for sampled Brazilian population does not apply on our sampled population of Panchkula district. Hence, a new regression model was derived for this population.

Published: October 2024

Dental caries is considered the most widespread human disease. Caries arrest therapy is now being marketed as a component of the essential dental care regimen. Researchers and dental clinicians are paying close attention to silver diamine fluoride (SDF), one of the antibacterial agents, for its ability to stop active caries.

This study aimed to evaluate the effect of SDF+KI in maintaining pulp health, dentin bridge formation and remineralization after partial caries removal in permanent teeth that were evaluated clinically and radiographically after different follow-up periods.

: Eighty teeth having deep occlusal carious lesions from 70 participants between the age 18-50 years were randomly divided into two groups: Group 1 (n= 40) using 38 %SDF+KI, while Group 2 (n= 40) using Resin Modified Glass Ionomer Cement (RMGIC). Soft deep caries was removed by low-speed handpiece and spoon excavators, then the teeth were evaluated radiographically. The teeth were evaluated at baseline and were compared at 6,12 months after the application to assess the vitality of the pulp, postoperative pain, dentin bridge formation and remineralization by using intraoral periapical radiograph using Diagora TM Optime and pixel grey values were measured using Diagora for window software.

: There was no statistically significant difference between the two groups in success rate and remineralization after a 6,12-month follow-up period (P ≤ 0.05). Regarding the dentin bridge formation, the SDF +KI showed better results, but there wasn't a significant difference between the two groups.

With or without 38% SDF+ KI application, the glass ionomer had remineralization potentials on the carious dentine and tertiary dentine formation. SDF gave better dentin bridge formation, indicating a good future in caries arrest.

Published: October 2024

Mucormycosis (Zygomycosis) is an opportunistic fungal infection caused by saprophytic fungus that invades rapidly and it is mainly associated with medically compromised patients. Paltauf first discovered this uncommon infection in human being in 1885.This clinical case report describes a post-operative prosthodontics management of acquired right side total maxillectomy defect caused by mucormycosis in a known uncontrolled diabetic female patient. As a treatment modality for mucormycosis, surgical resection of involved region has been done and surgical intervention creates a communication between the oral cavity and nasal cavity and missing some part of maxillofacial region with a loss of normal functions like mastication, swallowing, speaking, resonance etc. The goal of prosthodontics is the rehabilitation of missing oral and extraoral structures along with restoration of normal functions like mastication, speech, swallowing etc. But the prosthetic rehabilitation of maxillectomy defect can be challenging because of difficulty in getting adequate retention, stability and support. The obturator prosthesis is commonly used for rehabilitating this type of total maxillectomy cases by restores the missing structures and acts as a barrier to the communication between oral & nasal cavities.

Younger Generations of Americans in the 2024 Election
Authors: Popov Nikolay
Published: October 2024

In the 2024 elections, the participation of young people, whose weight in the electorate will reach almost half of the voters, will play an important role. These young people show considerable interest in politics and willingness to vote, which is largely due to their dissatisfaction with the state of affairs in the country and the inability of the current government institutions to solve the main problems of concern to young people. Their political involvement is not reflected in the growth of supporters of the two political parties. On the contrary, their numbers are decreasing, while the number of "independents" who do not belong to any party is growing. In this regard, more young people are voting not based on party affiliation, but on the basis of an idea of which party or candidates are able to solve the main problems of youth. Such problems in the 2024 elections are inflation, which prevents young people from obtaining higher education, their own housing and starting a family; increased illegal immigration through the southern border;  and bans on abortions. Additional events and problems affecting the electoral choice of young people have entered the current election campaign – the conflict in Ukraine, the war between Israel and Hamas, criminal trials of former President Donald Trump. The outcome of the November 2024 elections will largely depend on the participation of younger generations of Americans, as it was in 2020 and 2022.
FISA’s Section 702 in the Struggle of U.S. Groups of Power
Authors: Selyanin Yaroslav
Published: October 2024

In 2023 a struggle on an extension of section 702 of the Foreign Intelligence Surveillance Act (FISA) issue started in the U.S. Congress. This section regulates an intelligence community (IC) surveillance on non-U.S. persons when they are abroad. But IC members exceed an authority given them by FISA and broadly collected electronic communications of U.S. persons. This was the violating of the fourth amendment to the U.S. Constitution which prohibited unreasonable searches. It became the reason publicly sounded by members of the House of Representatives from both main parties for insisting on a significant reforming sec. 702. A case of IC illegal surveillance isn’t something new for the USA by itself. For example, even FISA appeared as a result of the Watergate scandal. But there was an unusual composition of sides which took part in this current case. The White House controlled by the Democrats and allied them IC was staying on 702’s renewal without significant amendments. But an unreconciled opposition included the Republicans and again the Democrats. Both sides seemed to be not ready to a compromise. But both sides underlined 702’s big importance as an instrument of National Security defending. So it was obvious that the compromise would be reached. And finally it was reached in a very unexpected way and D. Trump took part in it. This research is an attempt to find true reasons of this struggle between U.S. groups of power.
Hollywood and the Left Ideology
Authors: Khalilov Vladimir
Published: October 2024

. The article is focused on the reflection of Leftist ideas and the portrayal of their advocates in Hollywood filmmaking, as well as leftist activism within the cinema industry itself. The author examines the filmmakers' appeal to leftist narratives throughout Hollywood history, from the first "Red Menace" to the current struggle for social equity and justice. The author suggests that despite the temporary preoccupation of Hollywood figures with radical belief systems, these systems find themselves reflected on the screen only in exceptional cases, and that the dominant ideology in fundamentally capitalist and "bourgeois" Hollywood for many decades has been liberalism.

Published: October 2024

For several decades, the engine of modern society has been technological progress. Its innovations, new and constantly improving means and principles are the main components of our current coexistence. Information technologies shape and develop communication between market actors, economic relations, working environment, social interaction on large and small scales. That is why the replacement of previous technology with fundamentally new ways and methods, is always accompanied by changes in the world. If the informational, highly productive and highly networked world was a distant vision of the future just a few years ago, the active use of advanced technologies and gradual transition to a new format of activity have made it a real present. The main raw material for digital transformation is data, which is recognized as a decisive factor in the success of modern business. In the long term, the key competencies of successful companies will lie in collecting, processing, connecting and, most importantly, protecting this data. This is explained by the fact that the information formed in the information and communication system of the enterprise allows determining the efficiency of structural units to improve business processes, signaling trends in their development, thus helping managers to make informed management decisions. This information is of interest not only for the company itself, but also for competitors and cybercriminals, so it requires full protection. The article reveals the results of theoretical research into the protection of digital information, devices and resources in the modern world, and concludes on further improvement of the Russian legislation on digital security.

Published: October 2024

Wages occupy the largest share of income of citizens in most countries of the world and are the key to well-being and ensure the welfare of the population. In connection with global political and economic changes in the world, it becomes relevant to carry out an economic analysis of different countries, including indicators measuring the standard of living of the population, which very well reflect the state of the economy of these countries. Wages, as a significant part of citizens' incomes, are one of the indicators of the standard of living of the population. France is of interest as one of the Western countries participating in the sanctions war against Russia. The purpose of this work is to analyze wages and identify the main trends in their changes in recent years in France. The study analyzed average annual wages in France for 2000-2022, differentiated by category and gender. Based on the results of the analysis, a certain increase in the standard of living of citizens in the country was revealed in connection with an increase in average wages. A gradual decrease in the difference in wages between highly qualified employees with higher education and low-skilled employees performing manual labor was recorded. Some gender discrimination was identified, with women receiving lower wages than men in the same positions. However, during the analyzed period there was a decrease in the wage gap between both genders.

Stress testing has been proposed as a method of early warning of banking risks in the short and medium term. Recommendations has been given for organizing the stress testing procedure and specific stages of applying the stress testing scenario in the study of banking risks have been highlighted, taking into account the digitalization of banking services
WAYS TO INTRODUCE ENVIRONMENTAL TAXATION IN RUSSIAN REGIONS
Authors:   Vologda Scientific Center of the Russian Academy of Sciences, Palkina Darya S.
Published: October 2024

The issues of interaction between the state and business are topical, as companies provide socio-economic development of territories. At the same time, they leave a significant ecological footprint, which causes the need to stimulate environmentally responsible behavior. In this regard, we propose to improve such a financial instrument for regulating the activities of enterprises as environmental taxation. Russia already has a number of developments in this area, but implementation as a separate system is causing debate in the scientific community. In this regard, the purpose of the research was to study the Russian practice of introducing new and reforming the existing tax instruments of interaction between the private and public sectors in the context of environmental protection. Therefore, the article shows the practice of application of special tax regimes, investment agreements and projects, creation of special economic zones and realization of certain benefits and preferences for companies. The results of the study have shown that Russian legislation allows improving the implementation of environmental taxation at the federal, regional, as well as local levels. This opens up in the future the possibility of mathematical analysis of the implementation of this tool by different methods and identification of the most effective one. The methods of system analysis, tabular and graphical data visualization, statistical methods of initial data processing were used in the research. The information base was provided by the works of domestic authors, data from Rosstat, EMISS and news sources.
SECURITIES MARKET MANIPULATION USING CLOSED INFORMATION CHANNELS
Authors:   Moscow Aviation Institute (National Research University), Pelikh Evgeni A.
Published: October 2024

The development of social media and instant messaging platforms has changed the way financial information is disseminated, making it easier to access, but at the same time providing opportunities for potential abuse. Among these platforms, Telegram has gained significant popularity in the Russian-speaking segment, especially due to its investment advice channels. These closed channels, which often require a fee to provide access, have attracted many private investors seeking to capitalise on supposedly expert forecasts. However, this phenomenon also poses a significant risk of market manipulation, especially for low-liquidity stocks. The manipulation mechanism, which requires the presence of a certain number of private investors, involves attracting their interest in listed assets with a further increase in value due to increased demand. The manipulator uses the increased value of the asset to close the position and take profits. This article discusses the detailed mechanisms of such manipulations and suggests methods to combat them.

Published: October 2024

The paper analyses the Minority Game and focuses on analysis and computational modelling of several variants (variable payoff, coalition-based and ternary voting) of Minority Game using UAREI (User-Action-Rule-Entities-Interface) model. UAREI is a model for formal specification of software gamification, and the UAREI visual modelling language is a language used for graphical representation of game mechanics. The URAEI model also provides the embedded executable modelling framework to evaluate how the rules of the game will work for the players in practice. We demonstrate flexibility of UAREI model for modelling different variants of Minority Game rules for game design.

Authors: Mikelić Preradović Nives , Lešin Gordana , Boras Damir
Published: October 2024

In this paper we analyze the role and attitudes of kindergarten educators in the early ICT education. Our kindergarten survey among educators in Croatia showed the positive attitude towards ICT literacy in general, but it also showed that more than one third of educators has neither positive nor negative attitude towards the issue of early ICT education. The research results are compared to the most recent findings for other countries – Turkey, Hawaii, Sweden, Belgium, China, Greece, Portugal, UK, Australia, Israel, Chile, Slovakia, Singapore and Malaysia. The conclusion is that educators in countries that are still not obliged to use ICT in the preschool classroom, generally understand the necessity of their own ICT education and motivation to transfer their knowledge to the youngest learners.
First Confirmed Record and Ecologic Observations of Ophiocordyceps kimflemingiae (Hypocreales: Ophiocordycipitaceae) Infecting Camponotus americanus (Hymenoptera: Formicidae) in Tennessee1
Authors: Coffman Kathleen R. , Longmire Matthew L. , Chandler Jennifer G. , Grant Jerome F.
Published: October 2024

Entomopathogenic fungi in the clade Ophiocordyceps unilateralis (s.l.) parasitize formicine ants (more commonly known as carpenter ants), resulting in fungal fruiting bodies that emerge from the head of the infected ant. This phenomenon is better known as the “zombie-ant fungus.” In Oak Ridge, Tennessee, 191 infected ant specimens found on deciduous understory shrubs and saplings were collected from May to December 2022 and from March to May 2023. The diameter of stems on which these infected ants were attached was measured, host plant species were determined, and various morphologic characteristics (e.g., stroma length and perithecial plate diameter) of this fungus were documented. Deoxyribonucleic acid extractions and polymerase chain reaction analysis were conducted to confirm the identity of the fungus. Our results confirmed the presence of a fungal species within the Ophiocordyceps clade. Ophiocordyceps kimflemingiae was found infecting Camponotus americanus Mayr attached to stems of several understory shrubs and saplings, such as Lindera benzoin (L.) Blume (spicebush), Ulmus spp. (elm), Acer spp. (maple), Betula spp. (birch), and others. The size of fungal morphologic characteristics varied widely. For example, fungal stroma length ranged from <1 to >30 mm and perithecial plate diameter ranged from as small as 0.1 to >1.5 mm. This research has expanded the known geographic distribution of this fungus, demonstrated fungal morphologic variation, contributed to ecologic knowledge on stem diameter and mandibular death grip of infected ants on deciduous host plants, and expanded the listing of known plant species inhabited by infected ants.

The spatial variability of properties in sedimentary deposits can be assessed using approximation methods. A small number of direct measurements or their extremely uneven distribution leads to significant model errors. This article explores the possibility of using multidimensional approximation and regression splines, both considering spatially referenced direct observation data and using well log curves statistically linked to the modeled variables. It is possible to significantly reduce the forecast error by utilizing indirect data. The results can be computed for individual wells as for inter-well space, allowing for the creation of geological cross-sections of predicted properties and 3D models of their distribution. In order to demonstrate the effectiveness of the proposed approach, computational experiments were conducted using data from the stratigraphic range of the Georgievskaya and Vasyuganskaya formations in the Kazan field in southeastern West Siberia. Comparing the obtained forecast with the real, unknown values of the modeled variable at the time of its implementation showed a high quality model with determination coefficients up to 0.9.

This paper presents the results of lithological and geophysical studies of the Vikulov Formation sediments, as well as cyclostratigraphic and facies analyses. The geophysical and seismic data have been linked to identify and trace the main isochronal levels of the Vikulov Formation sediments in different facies zones of the West Siberian palaeobasin. The detailed alignment of the reflecting boundaries with the boundaries of sedimentation cyclites made it possible to conduct facies modeling of five sedimentation units of the Vikulov Formation. The modelling results showed that the sediments of the Formation were formed in the conditions of the underwater part of the avandelta of a semi-isolated shallow marine basin. The change in the source area location during the sediments formation was reflected in the whimsical structure and distribution of sediments in the sedimentation basin. The lithological heterogeneity of the Vikulov formation deposits determines the differentiation of filtration and reservoir properties and oil saturation.

The main objective of this paper is to increase the efficiency of planning horizontal wells and refine the geological model of formations of coastal origin. Based on a comprehensive analysis of geological and geophysical information and a description of the core, a facies and a 3D geological models of TP16 formations of coastal origin were constructed. These formations are characterized by strong lateral variability and low net to gross. In the course of this research, data from seismic inversion, geophysical studies of wells and production logging were used. Updated seismic correlation and an interval analysis of seismic cubes, together with the data from well test results, made it possible to reliably determine the stratigraphy and chronology of accumulation of the studied formations. As a result of the performed research, seismic attributes describing the geological structure of the deposits, as well as the distribution of productive volumes and reservoir properties were obtained for each formation. Also, the boundaries of tidal-fluvial channels and floodplain areas were identified based on seismic attributes. Taking into account the acquired data, the facies and 3D geological models were updated and the drilling of exploitation wells was planned. The accuracy of the new geological model was confirmed by drilling 8 horizontal wells with an average effective penetration of the reservoir of 1640 meters (82%) and an average permeability coefficient of 108 mD.

The article is devoted to the problem of predicting the viscosity of an oil mixture. Viscosity is an important characteristic of oil when calculating pressure losses due to friction when moving in a well, through field pipelines, through a network of main oil pipelines. In the presence of a complex branched network of pipelines and the flow of oil from various wells and fields in the condition of constantly changing production flow rates, a large number of mixture variants can be formed. Laboratory determination of viscosity for each theoretically possible mixture is practically difficult to implement, therefore, it is promising to determine the viscosity of the mixture by a computational method based on parameters amenable to additivity. Such parameters can be density, component composition and its derivatives, such as the content of paraffins, resins, asphaltenes, and fractional composition. The article analyzes various regressions of the first and second kind to obtain equations for determining viscosity depending on the mentioned parameters. A model is being developed to predict the viscosity-temperature dependence of an oil mixture based on information on density, paraffin content, resins, asphaltenes and fractional composition. The results can be applied to the calculation of field and trunk oil pipeline networks.

Background: Farmers conserve bean germplasm due to its importance in nutrition despite recent socioeconomic changes in their communities. The objective of the study was to analyze the edaphoclimatic conditions, morphometric and agronomic characters in seeds of bean varieties. Methods: Seeds of native varieties were collected in the Las Montañas region, Veracruz, Mexico, with data on temperature, precipitation and soil properties were extracted. The native materials were grown together with the Negro INIFAP variety and the commercial grains Michigan and Pinto. Qualitative variables (frequency and correspondence analysis) and quantitative variables were evaluated, the latter related to the plant, as well as dimensions and weight of the seed, following a complete and completely randomized block design, respectively. Result: Native varieties develop in ranges of 18.4 to 25.5°C and between 1 827 to 2 610 mm of precipitation and soils with average values of organic matter and pH of 5.89-7.04. Differences were present in the qualitative characters and in the number of seeds per pod (NSE), weight of one hundred seeds (WHSE) and seed dimensions (p≤0.01). The Amarillo milpa variety reached the highest NSE with 7.33 and Pinto stood out over the WHSE (33.41 g). The native varieties are classified as small ( less than 25 g 100 seeds), characteristic of the Mesoamerican race. In conclusion, the diversity in qualitative and quantitative characters in bean varieties reflects adaptations to contrasting edaphoclimatic conditions, which has implications for genetic improvement, food security and sustainability.

Este proyecto se basa en el asesinato de mi padre en 1998, cuando yo tenía 5 años. Un día, al buscar el nombre de mi padre en Google, me encontré con un artículo titulado «Tiempos sangrientos: una ola incontrolable de asesinatos, secuestros y robos azota Lima con más furia que El Niño mismo». En ese artículo había una fotografía con el nombre de mi padre; él estaba cubierto de sangre en el asiento del pasajero de su auto. Reconocí la camiseta que le había visto puesta. Años después, comencé a investigar a fondo su asesinato. Sentía la necesidad de construir una relación con él, y eso fue lo que me motivó.

Hace cerca de 11 años fui invitado por la ONG Wildlife Conservation Society (WCS) a tener una experiencia inmersiva en la reserva natural Bahuaja Sonene, en Madre de Dios, la intención era ver la posibilidad de desarrollar un proyecto de investigación visual en ese territorio. Esa primera experiencia fue tan intensa en términos vivenciales que decidí desarrollar un proyecto ahí. Así comencé a ir con cierta regularidad a este territorio ubicado al sureste en la Amazonía del Perú.
