Published: May 2024

Computer programs applied to disaster simulation are widely used and widespread today, taking as input various data types, from specific to the application area to DTMs (Digital Terrain Models). This need for data input and, in particular, data related to relief is very relevant in prediction procedures for forecasting catastrophes, such as the failure of tailings mining deposit dams. Therefore, it is of fundamental importance to know and quantify the quality of this input data in question, in order to effectively serve this application. To this end, in this research, several tests were carried out, using as a reference for best results those obtained with the introduction of DTM from a LIDAR (Light Detection and Ranging) flight survey, this data being used as one of the primary and input into HEC-RAS (Hydrologic Engineering Center-River Analysis System). Subsequently, these same data had their spatial resolution degraded, that is, the pixel size increased, generating models with worse quality for new inputs and obtaining new simulation results of mining dam failures. The test area of the B1 Dam, located in Brumadinho-MG, Brazil, was used as a laboratory, where one of the biggest mining disasters in the world recently occurred and, for which, there are real data from the area affected by the dam collapse. The results obtained demonstrated that the use of an DTM with a spatial resolution of at least 2.5 meters or better, with DTM class A cartographic quality compatible with the most recent Brazilian standard, would guarantee reliable results.
Mechanical characterization of 3D-Printed carbon fiber-reinforced polymer composites and pure polymers: Tensile and compressive behavior analysis
Authors: Faidallah Rawabe Fatima , Hanon Muammel M. , Szakál Zoltán , Oldal István
Published: May 2024

Fused deposition modeling (FDM) 3D printing is widely utilized for producing thermoplastic components with functional purposes. However, the inherent mechanical limitations of pure thermoplastic materials necessitate enhancements in their mechanical characteristics when employed in certain applications. One strategy for addressing this challenge involves the incorporation of reinforcement materials, such as carbon fiber (CF), within the thermoplastic matrix. This approach leads to the creation of carbon fiber-reinforced polymer composites (CFRPs) suitable for engineering applications. The utilization of CFRPs in 3D printing amalgamates the benefits of additive manufacturing, including customization, cost-effectiveness, reduced waste, swift prototyping, and accelerated production, with the remarkable specific strength of carbon fiber. This study encompasses tensile and compressive testing of distinct material compositions: recycled polylactic acid (rPLA), PLA enriched with 10 wt.% carbon fiber, pristine polyethylene terephthalate glycol (PETG), and PETG bolstered with 10 wt.% carbon fiber. Tensile tests adhere to the ASTM D3039 standard for specimens of rectangular shape, while the ASTM D695 standard governs the compressive testing procedures. Additionally, an inquiry into the influence of the primary 3D printing build orientation parameter on the tensile and compressive strengths of diverse materials was conducted. The outcomes reveal that rPLA exhibits superior mechanical properties in both tensile and compressive tests, irrespective of flat or on-edge build orientations. In the context of tensile strength analysis, it is noteworthy that rPLA demonstrated a superior performance, surpassing CFPLA by 30% in flat orientation and exhibiting a remarkable 39.2% advantage in on-edge orientation. Moreover, PLA reinforced with carbon fiber exhibits superior tensile and compressive properties compared to its PETG counterpart. A comparative analysis between CFPLA and CF-PETG indicates that CF-PLA demonstrates higher tensile strengths, with increases of 26.6 and 27.6% for flat and on-edge orientations, respectively. In the context of compressive strength analysis, rPLA surpassed CFPLA, PETG, and CF-PETG by 23.7, 53, and 67%, respectively. Intriguingly, the findings indicate that the incorporation of 10 wt.% carbon fiber diminishes the tensile and compressive properties in comparison to pure PETG.
Ecological influences and visual attention to infant phenotypes
Authors: Garza Ray , Pazhoohi Farid , Byrd-Craven Jennifer
Published: May 2024

In humans, the allocation of resources, such as parental care and attention, is vital to offspring survival. Life history strategies are influenced by cues in the environment, particularly those that signal the availability of resources. What has yet to be determined is how individuals allocate resources to infants as a function of perceived ecological harshness and life history strategy. In the current research we hypothesized that perceived ecology would influence infant ratings (Study 1), and that visual attention to infant phenotypes would be associated with life history strategies (Study 2). Study 1 investigated the effect of ecological conditions (control vs. harsh) on preferences to infant phenotypes (i.e., underweight, average weight, overweight). Participants (N = 246) were less likely to rate infants favorably under a harsh ecological condition. Study 2 investigated visual perception in processing infant images. Using an eye-tracking task, participants (N = 239) viewed images of infants while their eye movements were recorded. Participants displayed an early attentional bias (i.e., first fixation duration) to the head of the infant and focused most of their visual attention to the torso of infants (i.e., total visit duration). The results of the both studies indicate that ecological factors play an important role in rating infants, and data from eye-tracking demonstrates that phenotypes influence the amount of attention given to infants.
Microstructure development during rapid alloy solidification
Authors: Ji Kaihua , Clarke Amy J. , McKeown Joseph T. , Karma Alain
Published: May 2024

Solidification processing of structural alloys can take place over an extremely wide range of solid–liquid interface velocities spanning six orders of magnitude, from the low-velocity constitutional supercooling limit of microns/s to the high-velocity absolute stability limit of m/s. In between these two limits, the solid–liquid interface is morphologically unstable and typically forms cellular-dendritic microstructures, but also other microstructures that remain elusive. Rapid developments in additive manufacturing have renewed the interest in modeling the high-velocity range, where approximate analytical theories provide limited predictions. In this article, we discuss recent advances in phase-field modeling of rapid solidification of metallic alloys, including a brief description of state-of-the-art experiments used for model validation. We describe how phase-field models can cope with the dual challenge of carrying out simulations on experimentally relevant length- and time scales and incorporating nonequilibrium effects at the solid–liquid interface that become dominant at rapid rates. We present selected results, illustrating how phase-field simulations have yielded unprecedented insights into high-velocity interface dynamics, shedding new light on both the absolute stability limit and the formation of banded microstructures that are a hallmark of rapid alloy solidification near this limit. We also discuss state-of-the-art experiments used to validate those insights.

A Practical Paradigm Shift in Human Resource Management
Authors: Poór József , Tóth Arnold , Kálmán Botond Géza
Published: May 2024

Objective: The paradigm shift taking place in the science of human resource management has resulted in numerous changes in the theory. This process was significantly accelerated by the COVID-19 pandemic. This study shows how new knowledge appears in everyday practice in the countries of Central and Eastern Europe (Austria, Bulgaria, Bosnia and Herzegovina, Czech Republic, Hungary, Romania and Slovakia).
Research Design & Methods: Statistical processing of the data collected in a questionnaire survey shows how conservative crisis management is complemented by measures based on the new approaches organisations are using. In addition to the comparison between individual countries, the study also focuses on the size of the company as a factor determining crisis management decisions. It also examines the validity of general principles such as equal opportunity and difference management, both of which are people-centric principles.
Findings: The results of the survey show that the companies already understand modern theoretical knowledge. Despite this, among the practical measures, conservative responses such as layoffs or wage freezes are still used predominantly. The study draws attention to the need to speed up practical changes and implement the theory in practice.
Implications/Recommendations: The modern understanding and interpretation of HR is not alien or remote from the organisations that responded to our survey. Nonetheless, their imple­mentation of modern HR concepts has been relatively slow.
Contribution: We set out to create an international database that can serve as a basis for future research. We also show that the effect of the HR paradigm shift can already be demonstrated in practice, even if the uptake has been slow. Although the attachment to the past is strong, forward-‑looking crisis management measures that replace previous restrictive solutions are becoming more and more widespread. We hope our study helps modern crisis management in HR take stronger root.
Multigenerational Teams from the Perspective of Knowledge Management Based on the Example of a Selected Public University
Authors: Flaszewska Sylwia , Szymańska Katarzyna
Published: May 2024

Objective: The purpose of the article is to answer the following questions: What are the problems faced by university managers responsible for managing multigenerational work teams? Is it possible, and if so, what are good practices in integrating the potential of multigenerational teams of employees? What is the overall assessment of multigenerational teams – do university executives see them as an opportunity or a burden?
Research Design & Methods: Qualitative research in the form of a case study was carried out. This method included seven individual interviews with executives at the Faculty of Organization and Management at Lodz University of Technology.
Findings: Executives at the selected university identify various types of problems in managing multigenerational teams, while recognising opportunities to integrate the potential inherent in age-diverse teams. Respondents are mostly positive about intergenerational teams, but they also note some difficulties for managers related to having a multigenerational team.
Implications / Recommendations: The role of people responsible for leading multigenerational teams is becoming increasingly demanding. Striving to achieve equal involvement of representatives of all generations in the work is one of the most difficult challenges faced by university managers today. The effort, however, is worth making, as any diversity can positively influence the team and foster improvements in knowledge management.
Contribution: The article adds to the characterisation of each generation of employees with aspects from a knowledge management perspective.
Generation Z’s Expectations of a RemoteTeam Manager
Authors: Michałkiewicz Anna
Published: May 2024

Objective: The paper aims to categorise the expectations of Generation Z of managers managing remote teams.
Research Design & Methods: The research was carried out using the technique of written statements according to instructions. Analysis of the data collected was performed with the use of text-analysis software NVivo Pro as well as MS Excel for quantitative analyses. The study group consisted of 287 people.
Findings: The analysis shows that, apart from digital skills, remote managers need several people-oriented qualities and skills. Young people expect understanding, empathy, patience, and support in performing duties. They emphasised the role that trust plays for managers in motivating employees. The research also shows that there was some differentiation in men’s and women’s answers. Women more often emphasise patience and team support, the need to trust employees and team-building skills, while men proportionally more often wrote about self-control, self­-confidence, firmness and assertiveness, which is partly in line with the stereotypical perception of a male manager.
Implications / Recommendations: The results reveal the image of the remote manager Generation Z expects: a manager-psychologist that is proficient in computer operation and will organise work and care for his team.
Contribution: The author hopes that the research presented in this article fills a cognitive gap on Generation Z and its expectations of remote managers. Developing knowledge in this area is essential as this generation will play an increasingly important role in the changing labour market.
Wyzwania współpracy z robotem jako członkiem zespołu
Authors: Krawczyk-Bryłka Beata , Nowicki Krzysztof
Published: May 2024

Objective: To assess views on working with robots in a team and the most important concerns and expectations related to “employing” robots.
Research Design & Methods: Quantitative research was carried out using a survey questionnaire among a group of 593 IT specialists.
Findings: Robots are still treated mainly as tools, not as entities that participate in a team’s work. The belief that the presence of a robot on a team will not eliminate a human but instead replace it, performing dangerous and uncomfortable tasks and providing space to focus on more creative activities, leads some to view the employing of robots in teams in a positive light.
Implications / Recommendations: The creators of robots should be aware that robots will be team members that enter into relationships with people alongside whom they carry out professional tasks. Preparing – or being prepared, in the case of robots – to cooperate in such teams is a crucial task in modern human resource management.
Contribution: Research on teams in which robots cooperate with people is a novelty in the Polish literature on the subject. The article may help inspire further exploration of this research area.

the spectral quasi-linearization method (SQLM). Graphs are utilized to address the effects of new thermophysical
parameters. The entropy generation is calculated through various flow variables. The impact of a variety of parameters on entropy generation is discovered to be significant and shouldn't be disregarded.
Impact of triisopropanolamine on surface composition, crystallographic variation, and thermal behavior of C3A polymorphs
Authors: Kang Hyunuk , Lee Jihoon , Yang Jingwei , Moon Juhyuk
Published: May 2024

In this study, the impact of triisopropanolamine (TIPA) on both the crystallographic and surface properties of cubic and orthorhombic tricalcium aluminate (C3A) were investigated together with their hydration behavior and strength development. When TIPA was added during the grinding process, the pre-hydration and carbonation of C3A were effectively prevented, and crystal structural changes of C3A were confirmed. It leads to altering the hydration mechanism of C3A phases: in the case of cubic C3A, it promotes the formation of Al-hydrogarnet phases instead of OH-AFm phases even on the first day of curing. Similar hydration behavior was observed with orthorhombic C3A, but the phase transition of OH-AFm phases to Al-hydrogarnet occurs during a specific time period in 1–3 days. The latter was revealed as a very interesting endothermic reaction which can be the only heat absorptive behavior in complex cement hydration as reported so far.
Weight effects and the parametrization of the foot: English versus Portuguese
Authors: Garcia Guilherme D , Goad Heather
Published: May 2024

This article explores the possibility that even though English and Portuguese present similar stress patterns on the surface, the two languages may be formally different: whereas English offers strong evidence for the foot, Portuguese does not. We present new data on the relationship between syllable weight and antepenultimate stress in both languages. We experimentally show that weight effects in English are consistent with an analysis of stress that employs feet. Weight effects in Portuguese, in contrast, are not optimally accounted for by a foot-based analysis. Sonority effects captured in our experimental data from Portuguese further question the role that the foot plays in this language, but not in English. Additional evidence for the foot in English comes from word minimality constraints, which are never violated in the language, unlike in Portuguese, where violations are commonly observed both in the lexicon and in derived words.

Web-Based Digital Cell Library Characterization System
Authors:   NM-TECH, Moscow, Zelenograd, 124365, Russian Federation, Lyalinsky A. A.
Published: May 2024

A modern approach to the design of large-scale electronic computing equipment is inconceivable without using previous similar developments in the current project. It is quite natural in this case to use previously developed digital cell libraries as a base. When a separate library cell is included in a large project, there is no need to calculate signal transmission delays, power consumption and layout of the included cell — all this is obtained in advance at the stage of characterization of library elements. This approach allows to significantly accelerate the development of the product as a whole. The stage of characterization of digital libraries requires significant time and computing resources, which is why it receives increased attention from developers of computer-aided design systems for microelectronic equipment. This article discusses some aspects of building a digital cell library characterization system. The description of the web-based library characterization system developed by the author is given. The main features that distinguish the system from the rest are an interactive approach to building the system, its web—oriented nature (i.e. the system is located on a web server and is available for communication via any web browser on the Internet), a large number of auxiliary procedures, a unique graphical representation of the results obtained. In addition to the above, it may be noted the simplicity of preparing the source data, the ease of switching between the "initial circuit"/ "circuit with extracted parasitic elements" modeling modes, as well as between the so-called "modeling edges": the normal, worst and best combination of temperature and supply voltage. To speed up calculations in the system, two modes of parallelization of modeling processes are provided at the user's choice.
Challenging Norms and Practices in Women’s Beach Handball: The Bikini Debate
Authors: Hyde-Clarke Nathalie , Fonn Birgitte Kjos
Published: May 2024

Since 1978, the Norwegian Act for Gender Equality has created a strong emphasis on the importance of equality in all parts of society. This implies equal access to all cultural and welfare activities and services—including sports. In the media, we often see strong reactions to examples of discrimination based on gender, such as during the 2021 European Beach Handball Championship, when the Norwegian women’s beach handball team was fined by the European Handball Federation for refusing to play in bikini bottoms during their final matches. Media attention was given to the ensuing international outrage, which included well-known music artist Pink offering to pay on the team’s behalf in a gesture of solidarity. In November 2021, the sport’s International Federation agreed to allow women to compete in a similar uniform to men. This study analyses Norwegian newspaper coverage of the responses from Norwegian women athletes, politicians, and the international sports/media community from July 2021 to March 2022. It also provides an opportunity to determine to what extent the media framed and participated in calls for change.

This study assessed the serum leptin concentrations for development of gestational diabetes mellitus

This is a case-control study, included 120 participants (60: Gestational Diabetes Mellitus Cases and 60: Healthy Controls). We assed BMI, FBS, HbA1c, Lipid Profile and serum leptin.

The serum leptin concentrations were significantly elevated in patients with gestational diabetes mellitus when compared to controls (P=0.001**). There was a significant positive correlation between the serum leptin and BMI, FBS, HbA1c, Total Cholesterol and LDL (P=0.001**).

Based on study findings, significant elevated levels of serum leptin might be served as a marker for detection of gestational diabetes mellitus.

Authors: Gupta Mallicka , Singh Shivendra Kumar , Pandey Amita , Manar Manish Kumar
Published: May 2024

: Gestational Diabetes Mellitus (GDM) is one of the pregnancy complications characterized by carbohydrate intolerance that develops or is discovered during pregnancy. Physical inactivity and excessive gestational weight gain have been identified as independent risk factors for maternal obesity and pregnancy-related disorders, such as gestational diabetes. Awareness of the significance of physical activity for bodily and psychological health is vitally essential. The woman and her family members need to be swayed to change with time and let go of their myths and false cultural perceptions that exercise can harm the baby.

: To determine the physical activity pattern of pregnant women at the time of diagnosis with GDM.

: 188 pregnant women diagnosed with gestational diabetes mellitus was selected for the study. Pregnancy Physical Activity Questionnaire was used to calculate the duration; frequency, intensity, and type of physical activity during current gestational period. An average weekly energy expenditure in Metabolic Equivalent of Task (MET-h-week) was calculated. Demographic data including age, socioeconomic status, parity, literacy and working status were collected.

Data was analysed on 188 pregnant women diagnosed with GDM. The physical activity of moderate intensity was less performed by the pregnant women. None of the pregnant women were involved in vigorous type of physical activity. Only light intensity activities were performed by the study participants.

The study concluded light intensity activity was commonly carried by pregnant women thus a low level of physical activity was observed during the pregnancy.

Published: May 2024

Obesity has complications in relation to health as well as pregnancy. Bariatric surgeries gain interest among obese women to reduce the adverse obstetric outcomes. However, pregnancy post bariatric surgeries have benefits as well as risks. The study analyzed the effects of bariatric surgery on pregnancy, delivery, and postpartum period.

This is a retrospective study conducted in Bahrain Defense Force Hospital from September 2019 till August 2020. The study included women in the reproductive age who had bariatric surgery before planning pregnancy and a control group of women who did not undergo the bariatric surgeries. Comparison of obstetric outcome was done between both groups. Data included demographic characteristics, method conceived, antenatal pathway, delivery process and postpartum period. Results were presented as odds-ratios (OR) with 95% confidence interval (CI) and P-values. P values of less than 0.05 were considered statistically significant.

This analysis includes 2972 patients. 47 patients of them had undergone previous bariatric procedure. Patients with previous bariatric surgery were older 32.8vs 29.9 and interestingly heavier with BMI 34.5 vs 31.1. Patients with previous bariatric surgery had more antenatal complications 36% vs 18.5% (p=0.002). The most evident complication is gestational diabetes with 21.3% of patients who had bariatric surgery developed Gestational Diabetes Mellitus(GDM) during pregnancy compared to 8.9% of patients without the surgery (P=0.004). Both groups had similar start of labor, 1 stage of labor, 2 stage of labor, 3 stage of labor and prolonged 2 stage of labor. Caesarean section rate was similar at 42.6% vs 35.4% (p=0.31). After adjusting confounding factors, previous bariatric surgery increased length of stay in hospital more than 3 days with OR 2.3 95%CI (1.2-4.4) P=0.01.

Our study concluded the antenatal complications, Gestational diabetes as well as postpartum length of stay are significantly increased in post bariatric pregnant women. However, labor process and fetal outcome did not show significant difference.

Published: May 2024

: Worldwide 75 million women need post abortion care (PAC) services each year following safe or unsafe induced abortions and miscarriages. Majority of them do not wish to conceive in near future and are receptive towards using contraception. Contraceptive counselling and basket of choices should be made available to all women undergoing abortion and her right to decline or postpone this care should be respected while recognizing that each woman has a unique unmet need of contraception.

: To compare the acceptance and continuation of various contraceptive choices offered after first and second trimester abortion.

: A retrospective study was conducted at a tertiary care hospital in which women who underwent first and second trimester abortion over a period of one year were interviewed regarding their acceptance and continuation of the contraceptive method till six months post abortion.

: A total of 378 women underwent first and second trimester abortions over one year, of which 61.3% had resulted from failure of contraception. Women were grouped into Group A for those undergoing first trimester and Group B for women undergoing second trimester abortion for study purpose. Average age of women in group A was 28.9 years and in group B was 26.5 years. Mean period of gestation of pregnancy in group A was 7.5weeks and in group B was 19.5 weeks. In group A 96% parous women had conceived as a result of failure of contraception of which 90% were using natural method (Coitus Interruptus). Group B majority (76.3%) women were nulliparous and early parous (P1, P2) and indication for termination of pregnancy in them were gross congenital anamolies (GCA) in fetus while in rest of multiparous were due to failure of contraception. With group A 53.1% nulliparous women did not opt for any contraception whereas 48.6% primiparous and second parous opted for long acting reversible contraception(LARC) –Intrauterine contraceptive device(IUCD) in contrast to 66% multiparous opting for permanent sterilization at the time of abortion. In group B 45.3% nulliparous and early parous opted for depot medroxy progesterone acetate (DMPA) and 64.2% multigravidas underwent permanent sterilization.

: Post abortion care must include counselling and choice of contraceptive basket. Women with future reproductive plans preferred LARC after first trimester abortion whereas DMPA was most acceptable method of contraception after second trimester abortion. Women were most satisfied with LARC and permanent methods compared to methods that required daily intake of pills. There is need of effective contraceptive choices according to the reproductive plans of the women to reduce the burden, morbidity and mortality associated with abortions.
Comparison of Bishop’s score with transvaginal sonographic cervical assessment to predict success of induction of labor
Authors: Srivastava Subhi , Coumary A Sendhil
Published: May 2024

Induction of labor for medical or obstetric indications is a common practice in modern obstetrics. Evaluation of the cervix by Bishop’s score is universally used to predict the success of induction of labor. But it is a subjective method and many studies have shown that it is not a good indicator of success of induction.

To compare Bishop’s scoring system and trans-vaginal sonographic assessment of cervix in predicting the successful outcome of induction of labor.

This was an observational study conducted in a tertiary care center. 120 patients who met the selection criteria were included. Prior to the induction of labor the Bishop’s score and the sonographic scoring was assigned. Successful induction was defined as the patient entering the active phase of labor.

84% of participating women entered the active phase of labor. While 72.6% women had a normal vaginal delivery, 67.8% women delivered vaginally within 24 hours of induction. The TVS score (MGPICSS) of ≥2 predicted the successful induction with a specificity of 100% and sensitivity of 39.3% and AUC 0.74. In comparison, the Bishop score of ≥4 had a specificity of 75% and sensitivity of 44% and AUC 0.56. The prediction of delivery within 24 hours at the MGPICSS of ≥2 had a specificity of 100% and sensitivity of 42.9% and AUC 0.76. For the same, the Bishop’s score of ≥4 had specificity of 83.3% and sensitivity of 45.5% and AUC 0.71.

TVS assessment of cervix is a better predictor of successful labor induction in comparison to Bishop’s score.
Reactive leuco-thrombocytosis in a post splenectomized pregnant woman in labour: A case report
Authors: Keerthivasan Sree Supriya Muthaiyan , Kundavi K. M , Naaram Nithya M
Published: May 2024

Post-splenectomy diagnosis of infection based on WBC and platelet elevation is confounded by the fact that leucocytosis is a physiologic response to splenectomy, similar to the phenomenon of post-splenectomy platelet count elevation. Previous reports suggest that the WBC post-splenectomy in patients with sepsis is greater and more persistent than the WBC in patients without sepsis. However, specific values that can be used at the bedside to distinguish between a "normal" and "pathologic" WBC or platelet elevation are lacking. The clinician is often challenged to identify an infection in a post-splenectomy patient with an elevated WBC and prevent thrombotic events in case of thrombocytosis.

Activity on the securities market is mediated by the conclusion of civil law contracts. The provision of advisory services by an investment adviser is gaining popularity especially among novice and inexperienced investors. The legislator regulated investment consulting activities, including providing an opportunity for an investment adviser and his client to conclude a separate named investment consulting agreement. The article deals with the problems associated with the absence in the Law on the Securities Market of an indication of the obligation to conclude an investment consulting agreement in simple written form and the invalidity (nullity) such a contract in case of non-compliance with this form.
Efecto del método de Auto-curado con polímero Glicol de Polietileno en la resistencia a la compresión de los concretos fluidos F’c=280 kg/cm2, en Lima Metropolitana

Published: May 2024

En el desarrollo de las diversas actividades vinculadas a obras de construcción está presente el concreto, que, por sus propiedades y características favorables, ha llegado a considerarse como uno de los materiales más usado en el rubro constructivo actualmente. En relación a la relevancia de este material, es necesario garantizar que la resistencia final que alcance sea la requerida según las normativas vigentes, lo cual muchas veces no se asegura, debido a las deficiencias en la práctica del curado del concreto. El concreto auto-curado es uno de los concretos innovadores que sirve para mitigar el curado insuficiente del concreto debido a la negligencia humana, la escasez de agua en las zonas áridas, la inaccesibilidad de las estructuras, los costos adicionales que generan los materiales y el personal requerido para desarrollar esta labor, los terrenos difíciles y en zonas donde la presencia de sales en el agua puede afectar el comportamiento del concreto. En esta tesis se va a utilizar Glicol de Polietileno PEG-400 como material potencial que propicie el auto curado del concreto, para ello, obtendrá la dosificación óptima del PEG-400 en la mezcla según las resistencias de diseño del concreto en análisis a fin de proporcionar la humedad adicional en el concreto para lograr una hidratación más eficaz del cemento y reducir su auto-desecación, traduciéndose esto en una mayor retención de agua al concreto y contrarrestando la formación de fisuras. Este novedoso material hace que se supriman los procesos tradicionales del curado del concreto.

Image segmentation is a fundamental image processing technique that involves di-viding an image into distinct regions or segments to enable the analysis and extrac-tion of valuable information. It finds applications in various fields including medi-cine, pattern recognition, computer vision, and security surveillance. Different types of image segmentation techniques can be employed based on specific application requirements, including thresholding, region-based segmentation, edge-based segmen-tation, clustering-based segmentation, active contour models (Snakes), graph-based segmentation, watershed segmentation, and deep learning-based segmentation. the latter has become a powerful tool in image segmentation. Deep learning (DL) models can be trained on large datasets of images, allowing them to learn intricate relation-ships between pixels and object classes. This is particularly beneficial for challenging segmentation tasks. However, one significant challenge is the scarcity of labeled training data. To address this issue, self-supervised approaches using generative mod-els like Generative Adversarial Networks (GANs) provide a solution. GANs can gener-ate synthetic training data, which is useful for tasks where acquiring labeled training data is difficult or expensive, such as in medical imaging or remote sensing applica-tions. Additionally, GANs can generate realistic segmentation masks, which are cru-cial for tasks like medical imaging. In this study, we conducted a comparative analy-sis of DL-based segmentation approaches for COVID-19 CT scans. The evaluated approaches were assessed using metrics such as Dice Score, Specificity, and Sensitivi-ty. These metrics provide quantitative measures of the segmentation performance, allowing for an objective evaluation and comparison of the different techniques.

In this work, we present an energy efficiency study for a residential building located in the city of Al-Hoceima, Morocco. The aim is to bring the building into compliance with the technical requirements of the Moroccan Thermal Building Regulations (RTCM). To achieve this, several modifications and interventions were carried out, such as the use of hemp concrete for insulation and the integration of passive strategies to minimize energy loads. Similarly, this energy study is carried out as a simulation using TRNSYS software, so that the building is modeled as a multizone entity with an occupancy schedule. The simulation results show that the technical requirements of the RTCM are achieved using a construction containing hemp concrete with an optimum thickness of around 10cm, this thickness can be reduced to 4cm using double glazing, or to 1cm using controlled natural ventilation in summer and winter.

Modern cryptography is a key element of data security, ensuring the confidentiality and integrity of information. In an increasingly digital world, cryptography remains crucial for the protection of sensitive data. In this context, we propose a novel hybrid security system for encrypted color images using a DNA model, chaotic systems, and SHA256-MD5 hash functions as a basis. The proposed hybrid system includes DNA permutation and diffusion. In DNA permutation, we unpredictably rearrange the location of DNA image elements by using the logistic map of low computational complexity. In DNA diffusion, we diffuse the permuted image of DNA with the DNA image key generated by a 5D hyper-chaotic system, using a variety of algebraic operators such as the circular offset in both directions. Considering the experimental outcomes and security evaluation, we can infer that the proposed hybrid security system demonstrates a high level of security, resistance to existing attacks, and practical application suitability while maintaining speed.
