Utilisation des arbres de classification et de régression pour modéliser les données manquantes sur l’IMC, la taille et la masse corporelle chez les jeunes
Authors: Doggett Amanda , Chaurasia Ashok , Chaput Jean-Philippe , Leatherdale Scott T.
Published: May 2023

Introduction

Les données issues de mesures de l’indice de masse corporelle (IMC) autodéclarées par les jeunes comportent souvent de graves lacunes, ce qui peut avoir un effet important sur les résultats des recherches les utilisant. La première étape du traitementdes données manquantes consiste à étudier leur niveau et leur structuration. Or les études antérieures qui ont analysé les données manquantes sur l’IMC chez les jeunes ont utilisé une régression logistique, une approche limitée dans sa capacité à discerner des sous-groupes ou à obtenir une hiérarchie dans l’importance des variables, des dimensions pourtant susceptibles de contribuer grandement à la compréhension de la structuration des données manquantes.

Methods

Cette étude a utilisé des modèles d’arbre de classification et de régression (CART, pour classification and regression tree) stratifiés selon le sexe pour analyser les données manquantes sur la taille, la masse corporelle et l’IMC chez 74 501 jeunes participant à l’étude COMPASS 2018-2019 (une étude de cohorte prospective qui a porté sur les comportements de santé des jeunes canadiens), dans laquelle 31 % des données sur l’IMC étaient manquantes. Des variables telles que le régime alimentaire, le mouvement, les résultats scolaires, la santé mentale et l’utilisation de substances ont été étudiées afin de vérifier leurs associations avec les données manquantes sur la taille, la masse corporelle et l’IMC.

Results

D’après les modèles CART, le fait d’être à la fois plus jeune, de se sentir en surpoids, d’être moins actif physiquement et d’avoir une santé mentale moins bonne a produit des sous-groupes de filles et de garçons où il était très probable que des valeurs d’IMC soient manquantes. Les données manquantes sur l’IMC étaient moins probables chez les répondants de l’enquête plus âgés et ne se sentant pas en surpoids.

Conclusion

Si l’on se fie aux sous-groupes produits par les modèles CART, utiliser un échantillon au sein duquel les cas dont la valeur de l’IMC est manquante ont été supprimés conduirait à tenir davantage compte des jeunes en meilleure santé sur les plans physique, émotionnel et mental. Étant donné que les modèles CART sont aptes à discerner ces sous-groupes ainsi qu’à établir une hiérarchie dans l’importance des variables, ils constituent un outil précieux pour étudier la structuration des données manquantes et la manière appropriée de gérer ces dernières.

Published: May 2023

Introduction

A growing number of Canadian studies have examined the link between sleep and mental health. This research builds upon that work by investigating associations of sleep duration and quality with positive mental health (PMH) and mental illness and suicidal ideation (MI/SI) outcomes among youth and adults from three Canadian provinces (i.e. Ontario, Manitoba and Saskatchewan).

Methods

Using cross-sectional data from respondents 12 years and older (n = 18 683) who were asked questions on their sleep in the 2015 Canadian Community Health Survey – Annual Component, we conducted unadjusted and adjusted logistic regressions with self-reported measures of sleep duration and sleep quality as independent variables and a range of PMH (e.g. high self-rated mental health) and MI/SI indicators (e.g. mood disorder diagnosis) as dependent variables. Analyses were conducted of all complete cases and also stratified by sex and age group.

Results

Good sleep quality was associated with higher odds of PMH indicators (adjusted odds ratio [aOR]: 1.52–4.24) and lower odds of MI/SI indicators (aOR: 0.23– 0.47); associations remained significant when analyses were stratified. Meeting sleep duration recommendations was positively associated with PMH indicators (aOR: 1.27– 1.56) and negatively associated with MI/SI indicators (aOR: 0.41–0.80), but some associations did not remain significant when stratified.

Conclusion

This study provides support for associations between sleep duration and quality and indicators of PMH and MI/SI. Findings can inform future research and surveillance efforts that monitor sleep behaviours and indicators of PMH and MI/SI.

Xanthine Oxidase Inhibitory, Antioxidant Activity and Total Phenolic Content of Momordica charantia L. Fruit Extracts Prepared using Two Water Temperatures
Authors: Zainal Rashid Nurshazwani Wajiha
Published: May 2023

Momordica charantia L. fruit has good reputation for pharmacology and nutrition. Among the reported biological activities include antihyperlipidemic, blood glucose and serum uric acid reducing potentials. In most studies, M. charantia fruit extract was prepared in organic solvents. Nevertheless, water has been a good solvent to extract beneficial compounds with biological activities. Moreover, M. charantia fruit has also being consumed in the form of juice. In this study, the aqueous extracts of M. charantia fruit were prepared by blending the fruits in two differentwater temperature (25C and 100C). After the extracts were lyophilized, the xanthine oxidase inhibitory (XOI), antioxidant activity and total phenolic content of both extracts, along with allopurinol and ibuprofen were measured. From the results, both extracts exhibit XOI and antioxidant activity. The total phenolic content, XOI and antioxidant activity of the 25C and 100C extracts are not significantly different (p>0.05), which is in accordance with the negative correlation between total phenolic content and the activities of extracts. Interestingly, the XOI activity of both extracts are not significantly different from allopurinol (p>0.05), indicating the extracts effectiveness to inhibit xanthine oxidase enzyme. As a conclusion, it is postulated that the activities and total phenolic content of the M. charantia extracts are not affected by the water temperature.
Tyrosinase inhibition, antioxidant activity and total phenolic content of selected Mimosaceae pericarps ethanolic extracts
Authors: Ramli Salfarina , Ruangrungsi Nijsiri
Published: May 2023

The pericarp is the outer layer of a fruit. Often, pericarps are not used and are usually discarded. However, they may have untapped pharmacological potential. This study explored the tyrosinase inhibition, antioxidant activities, and total phenolic content of five pericarp extracts from Mimosacea family, namely Adenanthera pavonina, Archidendron jiringa, Leucaena glauca, Parkia speciosa and Pithecellobium dulce. Ethanolic extract was obtained after continuous extraction of dried pericarp with petroleum ether, dichloromethane and ethanol using Soxhlet apparatus. L-Tyrosine and L-Dopa are the substrates of tyrosinase in the monophenolase and diphenolase reaction, respectively. Both reactions are crucial in melanin production. Thus, tyrosinase inhibitor has broad potential in the fields of cosmetics and medicine. The antioxidant activity was evaluated by reducing power assay and metal chelating assay. Extracts inhibited both diphenolase and monophenolase reactions were analyzed by HPLC-PDA. From the results, at 500 μg/ml A. jiringa and P. speciosa extracts exhibited both monophenolase and diphenolase reactions. HPLC-PDA analysis detected catechin and epicatechin from the extract, respectively. Inhibition activity of A. jiringa and A. pavonina were not significantly different with kojic acid in monophenolase and diphenolase reaction, respectively. It can be implied that the inhibition of monophenolase reaction was attributed by the high total phenolic content, presence of flavanols and high reducing power. However, reducing power appeared irrelevant to the inhibition of diphenolase reaction, due to the lowest activity presented by the A. pavonina extract. This study showed A. jiringa and A. pavonina extracts inhibited tyrosinase enzyme in different reactions during melanin production.

Published: May 2023

The effectiveness of antibiotics has declined significantly due to development of drug resistance. Consequently, it results in millions of deaths due to infectious diseases. Many studies have suggested that bioactive compounds produced by endophytes could be an alternative to discover new antimicrobial compounds. Endophytes are microorganisms that reside within the tissues of living plants that cause no apparent harm to the host. Fungal endophytes may biosynthesize the same or similar compounds as their host plant and other diverse bioactive compounds, which provide various pharmacological activities. Therefore, this study aimed to conduct literature search on the antimicrobial properties of the isolated compounds produced by fungal endophytes associated with Rubiaceae. Literature was conducted on secondary metabolites of endophytic fungi via four databases; EBSCOhost, Google Scholar, PubMed, and Scopus. A search filter was performed to include only research articles from 2007 to 2021. The search was restricted to publications in English only. Overall, 29 publications were selected for full-text evaluation and were included in the study. Results showed that sixteen antimicrobial metabolites were isolated from six fungal endophytes of ten different plant species were identified. These compounds were classified as alkaloid, phenol, coumarin, steroid, diterpene, and meroterpene.
ANALISIS KESALAHAN PENGGUNAAN TATA BAHASA RUSIA DALAM PEMANDUAN WISATA DI PULAU BALI (STUDI KASUS TERHADAP PRAMUWISATA DI BALI)
Authors: Dewi Anggraeni Purnama , Fatah Imam Abdillah
Published: May 2023

Salah satu penggunaan bahasa Rusia yang sangat berkembang saat ini adalah di bidang pariwisata, khususnya dalam hal pemanduan wisata di pulau Bali. Banyaknya wisatawan Rusia yang datang ke Bali sekitar tahun 2000 an, secara otomatis menuntut ketersediaan sumber daya manusia yang mahir berbahasa Rusia, baik secara lisan maupun tulisan. Salah satu profesi yang dibutuhkan untuk menunjang kegiatan wisata ini adalah pramuwisata. Namun bahasa Rusia tidaklah semudah yang dibayangkan. Hal ini terlihat dari banyaknya kesalahan tata bahasa dalam tuturan lisan yang disampaikan oleh pramuwisata berbahasa Rusia. Melihat hal tersebut, penulis merasa perlu untuk melakukan penelitian ini dengan tujuan untuk mengetahui jenis tata bahasa apa saja yang sering salah digunakan oleh pramuwisata, dan untuk mengetahui faktor penyebab kesalahan tersebut. Metode yang digunakan dalam penelitian ini adalah deskriptif kualitatif dengan memaparkan hasil penelitian apa adanya. Sumber data diperoleh dengan teknik simak catat dan wawancara terhadap empat pramuwisata berbahasa Rusia. Hasil penelitian menunjukan bahwa pramuwisata berbahasa Rusia di Bali masih mengalami banyak kesalahan dalam penggunaan tata bahasa Rusia, khususnya terkait konjugasi verba, deklinasi nomina dan adjektiva, penggunaan preposisi, dan aspek verba bahasa Rusia. Adapun penyebab kesalahan tersebut adalah karena kerumitan tata bahasa Rusia yang sangat berbeda dengan tata bahasa Indonesia, sikap permakluman dari wisatawan Rusia terhadap kesalahan penutur, dan adanya tuntutan yang besar akan ketersediaan pramuwisata berbahasa Rusia dalam waktu singkat.
RHETORICAL MOVES IN TEN PAPUAN FOLKLORES: A CORPUS-BASED GENRE ANALYSIS
Authors: Tanusy Jeanyfer , Tanto Trisnowati
Published: May 2023

ABSTRACT. This paper aims to examine the basic structure that builds the narrative of ten of the folklores in Papua using the genre approach within the field of English for Specific Purposes (ESP). The study focuses on the presence of the rhetorical moves in each of the story, which is hoped to show the stories’ main communicative purposes as well as their schematic structures. The study uses descriptive-qualitative approach, which analyses the data interpretatively by applying Swales’ (1990) genre theory, the Move-Structure theory and combining it with the narrative elements from Labov’s (1972) Narrative Structure theory. The findings indicate all ten stories share similar structures in general despite being written by different authors—each of them has the moves orientation, complications, resolution, and coda. However, in the move realization, each story has different steps and/or step cycles. These findings indicate that the ten stories share the same communicative purpose: giving information about how some things come to be, and that they belong to the same genre. It is hoped that this research adds to the literature of genre analysis in the perspective of linguistics as well as enriches the analysis of folk literature in Indonesia.
As hierarquias escolares e a violência entre estudantes
Authors: Ávila de Lima e Dias Marian , Ferreira de Andrade Patricia , Cavalcante Carreira João Luiz
Published: May 2023

A partir das hierarquias escolares identificadas por Adorno, investigou-se a relação entre o desempenho escolar (destaque nas notas e atividades de classe – hierarquia oficial) e ser vítima ou praticante de maus tratos; a relação entre o desempenho em Educação Física, a popularidade (hierarquia não oficial) e a condição de sofrer ou praticar maus tratos entre pares e, ainda, se os estudantes que se destacam na primeira situação, também se destacam na segunda. As respostas aos  questionários e escalas aplicados a 223 estudantes do nono ano do Ensino Fundamental de escolas públicas de uma cidade da Grande São Paulo indicaram, sobre a hierarquia oficial, que os que nessa se destacam não tendem a ser vítimas ou agressores, enquanto aqueles que não se destacam, tendem a ser vítimas e agressores, conforme indicação de colegas. Se o mau desempenho na hierarquia oficial coloca o aluno como vítima ou agressor, é a sua posição na hierarquia não oficial que influencia qual desses papéis ele ocupará. Os considerados populares e com bom desempenho físico tendem a ser identificados como agressores e os impopulares e que não se saem bem em Educação Física, como vítimas. Além da correlação entre ser popular e sair-se bem nos esportes, que confirma a existência da hierarquia não oficial na escola, também há uma correlação entre popularidade e destaque na hierarquia oficial, sugerindo que a popularidade também é um aspecto importante nessa hierarquia. Esse dado leva ao questionamento sobre quais atributos identificam atualmente o “bom aluno” e quanto o reconhecimento do bom desempenho acadêmico pode ser confundido atualmente com um mero cumprimento de tarefas.

A Koppány-völgyi lepkefauna vizsgálatának első eredményei (Lepidoptera)
Authors: Horváth Bálint , Sáfián Szabolcs , Kovács Gyula
Published: May 2023

The Lepidoptera fauna in the Külső-Somogy region (Somogy County) in southwestern Hungary is generally under-recorded, despite the fact that the area hosts a diverse landscape and a wide range of natural and semi-natural habitats. As part of the landscape-scale habitat rehabilitation program the authors conducted a series of surveys on the butterfly and macro moth fauna (Rhopalocera and Macroheterocera) of the Koppány valley between the villages Somogydöröcske and Gerézdpuszta in 2010 including the catchment area and the floodland of the stream Koppány. In total 192 species were recorded between April and October. The Lepidoptera fauna is characterized by species associated with wet habitats near the stream (Lycaena dispar rutilus, Chariaspilates formosaria), but is also influenced by the warm broad-leaved woodlands and orchards that surrounds the valley (Meganephria bimaculosa). The change of land-use in the study area threatens the butterfly fauna through the intensification of agriculture (application of pesticides), and the complete cessation of animal husbandry.

Terrestrial isopod communities were studied in 27 Black locust forest in Transdanubia between 1995 and 2011 by hand sampling and pitfall trapping. The investigations yielded 17 species. The most common isopod species of Transdanubia (Porcellium collicola, Armadillidium vulgare, Trachelipus rathkii, T. nodulosus and Hyloniscus riparius) proved to be frequent in the Black locust plantations, too. All of these species are generalists. The assemblages consisted of 4-5 species. Dominant species of the communities were A. vulgare or P. collicola, alternatively. Species diversity and evenness of the assemblages were low. Strong association was pointed out between A. vulgare, P. collicola and T. rathkii while negative association was calculated between T. nodulosus and H. riparius.

Authors: Mavrodin Mihaela-Mariana , Dumitrescu Anca , Cambrea Simona Claudia
Published: May 2023

Introduction: Staphylococcus are gram-positive bacteria that inhabit both the skin and mucous membranes of both humans and animals.

Antimicrobial susceptibility testing is one of the most important laboratory procedures for infectious disease management.

Material and method: Between January 2017 and June 2019, in the Clinical Infectious Diseases Hospital (CIDH) of Constanta, 331 strains of staphylococcus isolated from various pathological products were identified and tested for antibiotic sensitivity: urine culture, stool culture, pharyngeal / nasal discharge, blood culture, sputum, vomiting fluid and various secretions.

Results: During 2017, 95 strains were isolated from patients hospitalized in CIDH, in 2018: 118, and in the first half of 2019: 124 staphylococcal strains.

An analysis by age groups shows that staphylococcus infection predominates in adults with a total of 196 (59.21%), and in children, less than 18 years: 135 (40.78%). Of the 196 adults, there are immunocompetent patients: 115 (58.67%), immunocompromised by HIV 40 (20.50%), and 19 were hospitalized in the intensive care unit (9.69%).

Regarding the predominant sex in staph infections, the most strains were registered in males: 179 (54.07%) and 152 in females (45.92%).

Out of the total strains of isolated Staphylococcus, 160 (48.33%) of Staphylococcus aureus were identified, of which methycillin resistant staphylococcus aureus (MRSA) 43 (26.87%).

Testing for Staphylococcus aureus strains with Oxacillin showed that 45 (28.12%) were resistant, Rifampicin 26 (16.25%) was resistant, Fluoroquinolones 29 (18.12%), and Cotrimoxazole / Sulfamethoxazole 27 (16.87%) of the strains were resistant.

Conclusions: There is a relatively high resistance to Oxacillin of Staphylococcus aureus strains and a relatively low resistance to fluoroquinolones, Rifampicin and Cotrimoxazole / Sulfamethoxazole, over the years studied.
Biochemical Modifications Associated with Bladder Cancer
Authors: Preda Cosmin , Vlad Anisoara-Marinela , Gurgas Leonard
Published: May 2023

Bladder cancer is the most common neoplasm of the urinary system, and urothelial carcinoma is the most common histological type of bladder cancer (approximately 90%), and represents the invasion of the basement membrane or lamina propria by urothelial cells.

Most people with bladder cancer have hematuria and the doctor should be consulted as soon as possible and a specialist scheduled to examine the bladder with a camera - cystoscopy.

The present study is a retrospective study that includes 174 patients from the Urology Clinic of the „Sfantul Apostol Andrei” County Emergency Clinical Hospital in Constanta in the period 2016-2020.

In the study, the 174 patients were divided into 2 groups. The first group is a study group and includes patients with an anatomopathologically confirmed diagnosis of urothelial carcinoma, while the second, control group, contains patients without a diagnosis of urothelial carcinoma. This study analyzes the metabolic disorders associated with bladder cancer.

There is a highly statistically significant association between hematuria and urothelial carcinoma.

The present study confirms a significant association between urinary tract infection and bladder cancer. The infection is associated due to the presence of blood in the urine, being an environment for the development of bacterial cultures.

A significant association is observed between hemoglobin and urothelial carcinoma, with patients developing anemia due to episodes of hematuria caused by the presence of bladder tumors.
Improved Barnacle Mating Optimizer-Based Least Square Support Vector Machine to Predict COVID-19 Confirmed Cases with Total Vaccination
Authors: Ahmed Marzia , Sulaiman Mohd Herwan , Mohamad Ahmad Johari
Published: May 2023

Every country must have an accurate and efficient forecasting model to avoid and manage the epidemic. This paper suggests an upgrade to one of the evolutionary algorithms inspired by nature, the Barnacle Mating Optimizer (BMO). First, the exploration phase of the original BMO is enhanced by enforcing and replacing the sperm cast equation through Levy flight. Then, the Least Square Support Vector Machine (LSSVM) is partnered with the improved BMO (IBMO). This hybrid approach, IBMO-LSSVM, has been deployed effectively for time-series forecasting to enhance the RBF kernel-based LSSVM model since vaccination started against COVID-19 in Malaysia. In comparison to other well-known algorithms, our outcomes are superior. In addition, the IBMO is assessed on 19 conventional benchmarks and the IEEE Congress of Evolutionary Computation Benchmark Test Functions (CECC06, 2019 Competition). In most cases, IBMO outputs are better than comparison algorithms. However, in other circumstances, the outcomes are comparable.

It contains also all the required steps needed to create the concrete models that were prepared to study the behavior of beams with partial substitution recycled rubberized concrete (RRC). The reinforcement of beams was various combinations of polymer GFRP and steel bars. The Rubberized concrete mixes were prepared by partial substitution 7.5 %, 10 %, and 12.5 % replacements by volume. The ratio of GFRP to steel reinforcement at mid‐span section was the second parameter investigated. Due to the large number of parameters affecting the behavior of Hybrid Reinforced T- Beam with partial substitution Recycled Rubberized Concrete, an extensive parametric study was performed using ANSYS version 15 program. Three parameters were investigated namely; Bottom RFT, compressive strength of concrete, and the existence of opening. The analytical results agree well with the experimental results in terms of mode of failure and the failure load values. The results indicated that although the flexural capacity of the tested specimen decreased with the addition of Crumb Rubber and reduced its self-weight. The failure load of the beam with partial substitution recycled rubberized concrete increases with bottom reinforcement by the GFRP bar or CFRP bar. Also, reinforced beams by CFRP bars had a higher failure load than reinforced beams by GFRP bars. Having an opening in hybrid reinforced T-Beam with partial substitution recycled rubberized concrete reduced the beam load capacity and maximum deflection. Also, using GFRP bars, and CFRP bars in the vicinity of openings in hybrid reinforced T-Beams increased the load capacity of these beams.

Road accidents have been identified as one of the main causes of death and have a significant effect on public health challenges, economic growth and development. The Iraqi transport infrastructure has suffered from the effects of war, carelessness, and lack of investment. As a result, road traffic accidents have increased, and the current efforts to address road safety are minimal in comparison to the growing level of citizen suffering. The objective of this study was to provincially analyze traffic accidents in Iraq using data from 2010 to 2020 to shed light on the current situation. Three key conclusions were made from the results: first, people aged 35 years and under was the age group recorded in the most traffic accidents; second, Al-Najaf province recorded the highest rate of traffic accidents; and third, COVID-19 lockdown in Iraq caused a 28.5 % decline in traffic accidents while fatality and injury rates fell by 28 % and 18.4 % respectively, when comparing with the data of the same period in 2019.
Two-Lane Highway Capacity Estimation Based on Geometric Features

The majority of roads in most countries are two-lane highways. These lanes quickly reach their capacity and must be upgraded on a regular basis. To do so, we must first determine the capacity of the street. The primary objective of this study was to determine the effect of carriageway width, the radius of the horizontal curve, and gradients on Passenger Car Unit (PCU) values as well as on capacity of two-lane undivided Highways, and more importantly, to develop a multiple linear regression model to determine the capacity of the highway when all of these factors are present, which has not been previously reported. Green shield’s model was used to estimate the capacity of each element for all thirty-six sections using flow and speed data. Different models were built using regression analysis to estimate capacity independently, and the combined model was developed as a result. It has been noted that with proportionate increases in carriageway width and radius of the curve, there is an equivalent rise in PCU values and highway capacity, providing improved comfort and safety to road users. It was also discovered that when the value of the gradient increases cause increase in PCU values but the highway capacity decreases, thereby increasing the vehicle operating cost. Where all of these characteristics are present simultaneously in a section, the resulting multiple linear regression model was proven to be appropriate. It is believed to be valuable to practitioners as well as in the development or revision of Indian highway capacity manuals.

Published: May 2023

On average, each person in Indonesia generates 0.45 kg of waste a day. The country is home to 231.8 million people, so the average daily waste generated is approximately 104.31 million kg. Malang, one of the biggest cities in East Java Province, generated 1,790.5 m3 of waste in 2001. Bank Sampah Malang (BSM), a waste bank program, has been established as a social engineering project to socialize and educate waste management in the community. The Malang Waste Bank (BSM) management policy was made as social engineering, providing socialization and education to the community to manage waste. This study aims to analyze the BSM policy by using the Analytic Hierarchy Process (AHP). Information from informants about policy evaluation shows that AHP consists of criteria, sub-criteria, and policy determination based on a green economy concept. The green economy includes economic, social, and environmental/ecological aspects. To sum up, BSM policy as the priority of social engineering requires institutional and environmental support as well as information availability.
Assessment of Slope Stability with the Assistance of Artificial Neural Network and Differential Evolution
Authors: Vu Vu Truong
Published: May 2023

This study aims for two purposes: firstly, using the Differential Evolution method combined with limit equilibrium methods to find the factor of safety of a variety of different configurations of slopes and soil parameters. Two patterns of the embankments are assessed, a one-layer soil pattern with 540 cases and a two-layer soil pattern with 24300 cases. Secondly, using these data to train and test an artificial neural network for predicting the factor of safety of slopes. The experimental data and values predicted by the artificial neural network correlate well with a linear coefficient of correlation of around 0.99. Given large enough training data, the proposed approach shows its reliability in quick evaluation of the slope stability without a long process of searching for a critical slip surface.

Published: May 2023

In the present study, laboratory model tests and numerical analysis are carried out to study the immediate, and consolidation settlement of shallow foundations rested on clayey soil. The purpose is to evaluate the immediate and consolidation settlement of different cases and compares them with the calculated values using theoretical equations; the numerical analysis is utilized by the Plaxis-3D program for developing the finite element model, whereas the soft soil model was used for simulation. It was studied the effect of three parameters on the behavior of the foundation for immediate and consolidation settlement, these parameters are soil cohesion, the pressure applied on the foundation, and layer thickness. The obtained results indicated that the simulation using the soft soil model underestimates the immediate settlement by about 30 % and gives excellent results for predicting consolidation settlement. The total settlement of shallow raft foundation rested on a clay layer of depth three times raft width to one time was increased by about 66 %. The consolidation settlement is much higher than the immediate in clayey soils, however, the average of immediate to consolidation settlement is equal to 0.3 % for pressure 20 kPa, and increases with rising applied pressure until it reaches 1.2 %. The numerical analysis revealed a lower value than the calculated using the theoretical equation for immediate settlement, while for consolidation settlement, the results are close except for the soft clay condition cu
= 20 kPa.

Published: May 2023

Concrete, which is based on the use of Portland cement as a binder, often becomes a construction material in the construction industry. Concrete itself, however, exists in a number of modifications that are intended for specific applications. Especially with regard to the development of materials engineering, variants were created, which include, for example, fiber reinforced concrete with improved tensile properties and alkaline-activated composite, which produces less CO2 emissions. The aim of the presented article is to verify the concept of using a combination of reinforced concrete and alkaline-activated material in the application of reinforced concrete beams without shear reinforcement. Components of the experimental program are static load tests, which are evaluated in detail with regard to the formation and propagation of cracks. Laboratory tests are also part of the experimental program, which focus on a detailed description of the properties and the possibility of a technological solution.

Published: May 2023

The effect of rotation rate parameter, cylinder diameter, and the variation of Reynolds number on the circular cylinder was the main object of this 2D numerical study. Rotating and stationary circular cylinder in steady and unsteady incompressible flow has been analysed. For each value of Reynolds number, we have varied the rotation rate parameter clockwise and anti-clockwise to visualize their effect on the drag, lift, and coefficients. All cases have carried out steady laminar, unsteady laminar, and turbulent regimes. A realizable K-epsilon model has been used to solve the Navier Stokes equations for the turbulent regime. Results were in good agreement with the recent findings.

Published: May 2023

The performance/weight ratio of fiber reinforced polymer matrix composites makes them the material of choice for structural applications in many fields such as aerospace, aeronautics, automotive and civil engineering...etc. In polymer matrix composites, the fibers used as reinforcement are mainly synthetic fibers such as carbon and/or glass fibers. To ensure the low cost of using fiber-reinforced materials in motor vehicles, it is proposed to selectively incorporate carbon fibers to enhance glass fiber composites along the roadway, and to enhance glass fiber composites along the main load path. For this purpose, we conducted a behavioral study of hybrid epoxy thermoset polymer matrix laminates to highlight the influence of alternate hybridization of glass and carbon fibers on the physical-mechanical behavior of the materials.The results obtained show that the alternated hybridation of the fibers has a significant influence on the tensile properties; and it affected the density, hardness and flexural properties significantly.
