RESISTANCE TO CRACK PROPAGATION OF HIGH-PERFORMANCE CONCRETE
Authors: Šušteršič Jakob , Ercegovič Rok , Polanec David
Published: December 2023

This paper discusses the results of investigations on the resistance to crack propagation carried out as part of a large-scale project to develop high-performance concretes (HPCs) for the secondary lining of a low and intermediate level waste disposal shaft. Four HPCs were investigated, in which the quantity of the binder component and the proportions of the two cements and the silica fume in it were varied. We have also added steel fibers to one HPC. The wedge splitting test method was used to determine the resistance to crack propagation. The results obtained show that all the HPC investigated achieve good resistance to crack propagation. The addition of steel fibers further improves this resistance.

Authors: Mirković Marija , Radević Aleksandar , Zakić Dimitrije , Savić Aleksandar , Askrabić Marina , Jevtić Dragica
Published: December 2023

Presented research was intentioned to clarify the effects of thermal treatment (ageing) of reinforcing steel products on their mechanical and deformation properties. In order to determine the effect of temperature, samples were exposed to room temperature (reference samples) and a temperature of 100 °C in duration of 30, 60 and 120 minutes, respectively. Tests were conducted on bars, coils and welded fabrics. After the thermal treatment, samples were exposed to tensile testing. The duration of the ageing treatment did not significantly affect measured properties of the tested products. Still, longer ageing process increased the yield stress of samples taken from coils by 7%, while the welded fabrics reached optimum values of yield stress and elongation after ageing of 60 minutes.

The subject of this analysis is the selection of the road alignment of Route 2a on the section Krupa - Bočac (Republic of Srpska). The complexity of the problem is reflected in the fact that a number of conflicting criteria of different stakeholders should be taken into account; i.e. criteria that are important from the aspect of road managers, criteria from the aspect of users and criteria society as a whole. The PROMETHEE method was used to determine compromise solution. Detailed comparative analysis of all parameters showed that variant 0 of the Krupa - Bočac section is a first ranked compromise solution. Sensitivity analysis has shown that the first place is stable by most criteria. Decision support framework presented in this paper can help future researchers and decision makers with similar problem.
ISOGEOMETRIC ANALYSIS OF A SPATIALLY CURVED BERNOULLI-EULER BEAM SUBJECTED TO MOVING LOAD
Authors: Jočković Miloš , Nefovska-Danilović Marija , Borković Aleksandar
Published: December 2023

Dynamic analysis of a spatially curved Bernoulli-Euler beam subjected to the moving load is considered in this paper. The isogeometric approach is used for the spatial discretization of the weak form of the equation of motion. Both the reference geometry and the solution space are represented using the same NURBS basis functions that guarantee an accurate description of beam’s centerline. The time integration is done by the explicit technique. The presented formulation is validated by the comparison with the existing results from the literature for the curved beam subjected to the constant load moving with the constant velocity.

GENDER DIFFERENTIATION OR EQUALITY IN TRANSPORT PROJECTS: CASE STUDY ROAD SECTOR MODERNIZATION IN THE FEDERATION OF BOSNIA AND HERZEGOVINA
Authors: Jokanović Igor , Ljubijankić Selma
Published: December 2023

Transport projects provide us with better, faster roads, save travel times, but also lead to occurrences of health and safety risks. Data shows that males are the group that are most affected by such risks. However, they become far less cooperative when confronted with this fact. At the same time, women are the group that is more likely to accept new methods or ideas concerning road projects. They are also more focused on road safety and concerned about associated community health and safety risks. Yet, women are far less involved in any kind of official interaction, and that is why their scope of interest is more likely to be neglected. The paper analyzes how transport projects affect differently women and men and presents recommendations to improve benefits for both genders.

Published: December 2023

One of the first steps in reducing energy consumption for heating and cooling buildings is developing of thermal insulation envelope of building. Nowadays contemporary walls have constructions composed from different layers – which make composite structures. We have developed model of the heat balance and based on that model simulation that could analyze and determine the heat balance and temperature distribution inside the buildings in dependence from external conditions and temperature distribution inside the walls and on their boundaries between different layers. All cases represents passive isolation, where the heat balance depend only on materials characteristics, on their heat transfer coefficients, thermal conductance properties and thickness of used materials. For various combinations of today available construction and insulating materials, we have calculated the overall coefficients of heat transmission. Our calculations confirm advantage of usage hollow bricks instead solid bricks, and placing insulation layers on the outer side of walls. Furthermore, those simulations will serve as test for the wider project of the dynamic heat flow experiments in general structures and among them in nanostructures as well.

Authors: Krstić Hristina , Petrović Vladana , Živković Milica , Kondić Slaviša , Medar Katarina
Published: December 2023

Space that cannot be precisely defined by certain conventional spatial chategory (for example as interior or exterior), because it takes over the characteristics of variuous spaces, expresses ambivalent features. Such a spatial chategory often occurs in complex architectonic structures, that are created by the insertion of spatial layers one within another. Its presence enriches the spatial experience of the architecture and contributes to the creation of unique ambience values, that affect the residents’ lives. This paper has the goal to investigate the spaces of this kind in housing architecture and to determine their importance in the terms of housing comfort.

Published: December 2023

The period between the two World Wars was a golden age of the rise of Belgrade and other cities in Serbia. After the Second World War, there was a period of stagnation in urban areas, but there were also high achievements in the field of urban reconstruction. With the social changes that took place in the last two decades of the 20th century, with the advent of transition, the attitude towards the urban renewal of cities in Serbia, especially Belgrade, also changed. These changes brought higher quantity, and lower and lower aesthetic quality of new construction in cities. This possible view of a small part of quality, but also inappropriate architectural - urban practice in the field of urban reconstruction of Belgrade, is accompanied by a picture of the social context in its basic features.

Sonorism in Compositions by Soviet Composers for Non-Register Button Accordion
Authors: Eshchenko Aleksei Borisovich
Published: December 2023

The object of the research is the works of Soviet composers for the non-register bayan (non-register accordion). The subject of the research is the sonorous technique. The aim of the study is to examine the specific application of sonorism in the works of Soviet composers for the non-register bayan. The author identifies the types of sonorous soundings and the ways they are formed; considering their textural, dramatic, and depictive significance. The materials of the article can be used for the professional activities of bayanists and composers, and can be included in the courses. The methodological basis of the research includes a comprehensive approach, which incorporates scientific methods of induction and deduction, typology, comparative, structural, systemic, and historical approaches. The scientific novelty of the research lies in the fact that the sonorism in compositions for the non-register bayan is specifically explored for the first time. As a result of analyzing works of Soviet composers for the non-register bayan (original compositions, arrangements of folk melodies, adaptations), the author of the article concludes that sonorous technique is not frequently used in them, and the sonorous soundings employed (lines, spots, and stripes) are generally consist of a small number of sounds and brief. Nevertheless, by selecting the representative examples from the works of the renowned Soviet composers to illustrate, the author of the article demonstrates that sonorous soundings are employed in crucial dramatic moments, serve various depictive functions, and provide a background for the melodically leading voices. Identified applications of sonorous technique in works of Soviet composers for the non-register bayan represent a preparatory evolutionary stage leading to the "flourishing" of sonorism in music for the cassotto-сonverter instrument in the second half of the 20th century and the first half of the 21st century.
Experimental legal regime in the field of digital innovations: on the issue of ensuring legal certainty
Authors: Chereshneva Irina
Published: December 2023

The rapid development of digital technologies that transform objective reality by their implementation, combined with the need for the Russian state to rely mainly on internal resources (which is due to the introduction and expansion of the sanctions regime of unfriendly countries against Russia), "calls" for the search for effective mechanisms and tools capable of: 1) to ensure technological sovereignty, 2) to mobilize the digital economy, 3) to preserve the well-being of our society. One of these mechanisms may be an experimental legal regime in the field of digital innovation (hereinafter referred to as EPR), the study of the essence of which is the subject of this work. In the course of the research, the author pays special attention to: 1) consideration of the category "legal experiment"; 2) disclosure of the essence of the EPR through the study of the category "legal regime of entrepreneurial activity", including within the territories with a special regime of entrepreneurial activity; 3) consideration of the issue of ensuring the principle of legal certainty in the context of the EPR. The following methods of scientific research were used in the study: analysis, synthesis, generalization, analogy, etc.; a systematic approach, special legal and comparative legal methods were used. The main conclusions of the conducted research are: - firstly, the system of entrepreneurial legal regimes can be represented by the following triad: general, special, extraordinary; in relation to territories with a special regime of entrepreneurial activity, when it comes to a special preferential regime; - secondly, the dual legal nature of the EPR makes it possible to consider it both as one of the types of territory with a special regime of entrepreneurial activity, and as a legal experiment; - thirdly, the intermediate place of the EPR between the advanced legal regulation is determined and the postponement of legal regulation, which allows us to talk about the dynamism of legal certainty; fourth, EPR can be considered as an effective means of overcoming the effect of lagging legislation only when legality is not replaced by expediency.

Authors: Meziti Alexandra , Smeti Evangelia , Daniilides Daniil , Spatharis Sofie , Tsirtsis George , Kormas Konstantinos A.
Published: December 2023

Background-Aim

Protistan communities have a major contribution to biochemical processes and food webs in coastal ecosystems. However, related studies are scarce and usually limited in specific groups and/or sites. The present study examined the spatial structure of the entire protistan community in seven different gulfs and three different depths in a regional Mediterranean Sea, aiming to define taxa that are important for differences detected in the marine microbial network across the different gulfs studied as well as their trophic interactions.

Methods

Protistan community structure analysis was based on the diversity of the V2–V3 hypervariable region of the 18S rRNA gene. Operational taxonomic units (OTUs) were identified using a 97% sequence identity threshold and were characterized based on their taxonomy, trophic role, abundance and niche specialization level. The differentially abundant, between gulfs, OTUs were considered for all depths and interactions amongst them were calculated, with statistic and network analysis.

Results

It was shown that Dinophyceae, Bacillariophyta and Syndiniales were the most abundant groups, prevalent in all sites and depths. Gulfs separation was more striking at surface corroborating with changes in environmental factors, while it was less pronounced in higher depths. The study of differentially abundant, between gulfs, OTUs revealed that the strongest biotic interactions in all depths occurred between parasite species (mainly Syndiniales) and other trophic groups. Most of these species were generalists but not abundant highlighting the importance of rare species in protistan community assemblage.

Conclusion

Overall this study revealed the emergence of parasites as important contributors in protistan network regulation regardless of depth.

Authors: Sanjay KS , Kantharajanna Usha Bangalore , Sruthi Ratakonda , Kalavala Chandana
Published: December 2023

Congenital Syphilis (CS), also known as mother-to-child transmission of syphilis is caused by Treponema pallidum. Infected pregnant women can transmit the infection vertically to the foetus. Diagnosis of CS can be difficult because more than two-thirds of affected infants remain asymptomatic at birth, and signs may be non-specific or subtle. In this case series, seven cases of CS with varied presentations are described. In cases 1, 2, 6, mothers were screened after the baby was tested positive for Venereal Disease Research Laboratory (VDRL) test. In two cases (Case-4,6), the mothers received inadequate treatment for syphilis antenatally. In the present case series, Case-6 presented with renal manifestations early in the course of the disease, Case-2 had skin manifestations like vesicular lesions and peeling of skin and Case-7 had symptoms suggestive of meningitis. Because of its varied presentations, high index of suspicion is the key to diagnosis and treatment of CS and prognosis. Screening of pregnant women and treating them is the most effective way in preventing CS and its related morbidity and mortality.
LATCH Score as a Tool to Predict Weight Gain in Term Babies at Six Weeks Post-discharge: A Prospective Cohort Study
Authors: Lakshmi S Kavitha , Jagadish AS , Premalatha R , Ravichander B
Published: December 2023

Introduction: The LATCH score is an acronym representing L- LATCH, A- Audible swallowing, T- Type of nipple, C- Comfort, H- Hold. It is a comprehensive yet simple breastfeeding assessment tool used to evaluate breastfeeding practices. Babies with a poor LATCH score at discharge are at an increased risk of early breastfeeding cessation and inadequate weight gain. According to World Health Organisation (WHO), only about 44% of infants aged 0-6 months worldwide were exclusively breastfed from 2015-2020, with a goal of increasing this rate to atleast 50% by 2025. There have been very few studies conducted in developing countries regarding this matter. Aim: To determine the correlation between the LATCH score and weight gain at six weeks post-discharge in term babies. Materials and Methods: This prospective cohort study was conducted at MVJ Medical College and Research Hospital, Bengaluru, Karnataka, India, from January 2023 to June 2023. The study included 355 healthy term and singleton babies. LATCH scores were assessed at the time of the first feed, 24 hours, 48 hours, 72 hours, and at the time of discharge. Mothers with a low LATCH score and the reasons for the low score were identified, corrected, and counselled until discharge. Weight gain velocity was analysed at the six-week follow-up. Analysis of Variance (ANOVA) was used to compare the mean values between variables, and Pearson’s correlation was used to analyse the correlation between the LATCH score and weight gain at six weeks post-discharge in term babies. Results: In the present study, the mean age of mothers was 26.21±5.40 years, and there were 200 males and 155 females babies. The mean LATCH score at the time of the first feed was found to be 3.91±1.09, which improved to 5.61±0.890, 7.03±0.742, 7.67±0.578, and 9.12±0.662 at 24 hours, 48 hours, 72 hours, and at the time of discharge, respectively. The reasons for a poor LATCH score were mainly attributed to primiparous mothers (42%) and incorrect positioning (35.5%). A significant positive correlation was found between the improvement of the LATCH score and weight gain at the six-week follow-up. Conclusion: The LATCH score was found to be a simple tool for identifying mothers and infants who require breastfeeding support and timely intervention to sustain breastfeeding. The LATCH score can serve as an effective predictor of weight gain at the six-week follow-up.

Coimbatore, with a high development index, was selected using a three-stage stratified random sampling approach involving 120 households. Utilizing tools like the development index, econometric models, scoring/ranking techniques, and non-market valuation methods, values ranged from 0 to 1, indicating low to high development. An adoption index classified respondents into low, medium, high, and very high adopters, evaluating cashless transaction adoption. The logit model pinpointed factors influencing cashless transaction adoption among farm households.

Results and Conclusion: This study shows a gradual shift towards cashless transactions among farmers, primarily driven by government policies promoting bank account usage for subsidies and loans. In Coimbatore, a developed district in Tamil Nadu, the adoption index is 63 per cent for non-agricultural and 44 per cent for agricultural transactions, highlighting a significant difference. The slow adoption is attributed to incomplete sales portal transformation and farmers' limited awareness of online platforms for input purchases. Despite challenges, farmers exhibit a positive attitude, emphasizing the importance of addressing issues such as financial literacy, internet connectivity, and infrastructure for successful cashless transactions.

Community health outreach is part of community-based health care, an extension of facility-based primary care services used to reach the underserved. Slums population in sub-Sahara Africa has been growing by 9 million persons per year making slum occupancy to form more than 56% of urban settlements. A slum is characterized by inadequate access to safe water, inadequate access to sanitation and infrastructure, poor structural quality of housing, overcrowding, and insecure residential status. People in slums due to their environment are more vulnerable to communicable diseases, respiratory diseases, malnutrition and accidents. The main objective was to identify the 10 top most prevalent diseases in Korogocho slums. A cross-sectional study design was applied. Study period was between January 2021 and December 2021. Data was collected through a series of 12 Community health outreach sessions at Korogocho slums in Nairobi, Kenya. Secondary data was extracted and analyzed using SPSS version 25.A total of 3699 individuals were treated, there were more females (67.96%) than males (32.01%) and at least 1 person was identified as a transgender. Age group of 0 to 59 months (472 patients) had more males than females while 19 to 59 years old (1413 patients) females formed majority of Community health outreach attendants. Modal age group was 19 to 59 years among females and 0 to 59 months among males representing 45.28% of the total patients. An average of 308 patients was seen per session. Respiratory tract infections (44.8%), skin diseases (13.8%), abdominal diseases (13.2%), musculoskeletal disorder (7.86%), eye conditions (4.75%), genitourinary diseases (4.18%), ENT diseases (3.9%), hypertension (3.36%), dental problems (2.1%) and wounds and injuries (2.05%) respectively formed the 10 most prevalent diseases in Korogocho slums. Public health intervention of wearing of medical face mask to prevent allergens and airborne infections is highly recommended, prompt and timely treatment of respiratory diseases will help in reducing respiratory related complications. Cost effective and sustainable water treatment options should be availed to the locals to help in improving water quality so as to reduce infective abdominal-diseases.

The field investigation was conducted during the Kharif 2021 and 2022 at the Central Research Farm (CRF) of Naini Agriculture Institute, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj, Uttar Pradesh, India. The experiment was organized in a Randomized Block Design, comprising twelve treatments, each replicated thrice. The treatments included Chlorantraniliprole 18.5 SC (0.5 ml/l), Lambda cyhalothrin 2.5% EC (10 ml/l), Thiamethoxam 25 WG (10 gm/kg), Profenophos 50 EC (3ml/l), Cypermethrin 10 EC (4 ml/l), Neem oil 3% (30 ml/l), Verticillium lecani 1.15 WP (15 ml/l), Spinosad 45 SC (0.3 ml/l), Emamectin benzoate 5 SG (0.40 gm/kg), Indoxacarb 15.8 EC (1.5 ml/l), NSKE 5% (50 ml/l), and control plot. The results showed that the lowest population of stem borer was identified with Emamectin benzoate 5 SG (2.24), (0.82) and (3.61), (2.33) followed by Chlorantraniliprole 18.5 SC (2.41), (1.01) and (3.82), (2.46) during the Kharif seasons of both 2021 and 2022. Neem oil 3%, NSKE 5% were found to be least effective over the other treatments and is significantly superior over the control.

Aims: The study aims to verify the relationship between the positioning of the shoulder and the cervical spine in sitting posture in university agents associating it with musculoskeletal pain.

Methodology: To carry out this study, the evaluation of the prevalence of musculoskeletal pain using a recall record was used and the projection angle of the head and shoulder in the sitting position was quantified. The selected group is made up of university agents from UNICENTRO who agreed to participate in the research.

Results: The results show the main change in the shoulder angle in men with pain in the left shoulder, the other measures do not show significant changes between people with and without pain.

Conclusion: The values obtained for the angular variables (shoulder angle and head angle, measured with passive markers in the ear, cervical spine (C7) and acromion) evidenced in this study demonstrated that some university agents presented postural dysfunctions related to poor posture in their work environment in relation to the correct posture described in the literature.
Prediction of Mortality in COVID-19 Patients Using Diagnostic Value of SaO2/FiO2 and PaO2/FiO2 Ratios at Hospital Admission: A Retrospective Cohort Study
Authors: El-Ali Myrella A. M. , Sejópoles Marcia D. , Gomes Luciano T.
Published: December 2023

Background: Approximately 20% of COVID-19 patients have an arterial blood oxygen partial pressure to fractional inspired oxygen concentration ratio (PaO2/FiO2) of less than 300.

Objective: To analyze the diagnostic value of oxygen saturation of arterial blood (SaO2)/FiO2 and PaO2/FiO2 ratios measured upon hospital admission for predicting mortality in COVID-19 patients.

Methods: A retrospective cohort study was conducted at two hospitals in the Central Region of Brazil, involving 199 COVID-19 patients hospitalized from March to August 2020. Data were collected from medical records. Respiratory markers were obtained from blood gas analysis and pulse oximetry measurements taken upon admission. Receiver Operating Characteristic curves were constructed to assess the accuracy of the studied ratios in predicting mortality among the analyzed patients.

Results: There were 33 deaths among the total hospitalized COVID-19 patients. Among those with available data on PaO2/FiO2 and SaO2/FiO2 measured upon admission, 22 (20.6%) deaths occurred. Notably, the severity of ARDS correlated with an increased risk of death (p=0.001) within this subgroup. Patients who died had lower PaO2/FiO2 and SaO2/FiO2 ratios compared to survivors. Both PaO2/FiO2 and SaO2/FiO2 ratios measured upon hospital admission were accurate parameters for predicting mortality in COVID-19 patients. The cutoff point of 280 for PaO2/FiO2 and 290 for SaO2/FiO2 showed satisfactory sensitivity in predicting death among the analyzed patients.

Conclusion: SaO2/FiO2 and PaO2/FiO2 ratios measured upon hospital admission exhibited good sensitivity and accuracy in predicting mortality in hospitalized COVID-19 patients. This finding may prove valuable in guiding future pandemic decision-making in healthcare practice and contributing to oxygen management for both non-invasive and invasive ventilation.
