We study ant community in Obala (Cameroon), a forest-savannah ecotone to determine diversity and functional structure. Ants were sampled using pitfall, bait and hand-collecting in four habitats. Ant community was characterized using genera and species richness per subfamily, species richness and Pielou index for diversity, Venn diagrams for the distribution of species richness, multinomial model and Individual value to determine habitat specialization, and Multiple Correspondence Analysis to identify functional structure. We identified 104 ant species belonging to 34 genera and six subfamilies; 90, 31, 35 and 17 ant species were collected respectively in cocoa farms, food crops plantations, teak forests and savannahs. Myrmicinae, Ponerinae and Formicinae were the richest subfamilies at genera and species levels. Cocoa farms were richer and more diverse (S = 90; E = 0.68) than other habitats. Eight species were shared amongst the four habitats and the high number of generalist species occurred between cocoa farms and teak forests. Indicator species were mainly ground-dwelling ant species, confirming the high level of environmental threat in Obala. Four functional structures were identified: non-dominant ground foraging species with low ability for space control; tree foraging species with low ability for food control found in cocoa farm; subdominant species that exert medium level of food and space control; and ubiquist numerically dominant ant species with high aptitude for food and space control. In a functional structure involving ant species that plays the same or complementary roles in the ecosystem functioning and determine network of species assemblages.

Published: January 2025

Seasonal changes in carabid assemblages (Coleoptera Carabidae) inhabiting four sites near Mostaganem (NW Algeria) were investigated from April 2019 to March 2020 by means of pitfall trapping. Notable changes were found in all sites. In a citrus orchard (31 species, 710 specimens) spring breeders were more frequent. An olive grove (34 species, 1219 specimens) was dominated by Orthomus abacoides (974 specimens). Activity-density was concentrated in spring and autumn. An Eucalyptus forest (21 species, 292 specimens) showed unexpected species diversity and is a secondary habitat for large predators and forest taxa. In a fallow humid zone, a high number of species (80) and specimens (4366) were captured. Activity-density peaked in spring but was intense in all seasons. Hygrophilous and generalist taxa were dominant throughout all seasons. Seasonal changes are thought to be due to varying phenology and life cycle of species. Diversity was influenced by a few dominant species in all sites, but it was high in the fallow humid zone and decreased in cultivated areas. Comparison between sites was difficult because of the heterogeneity of species composition, which also applies to other Algerian cultivated lands, forests, and wetlands. Fine ecological tunning to environmental factors and random dispersal of taxa are likely causing seasonal faunal heterogeneity.

Authors: Madroñal Melvin H. , Relox Richel E.
Published: January 2025

In the Philippines, mangrove coverage has been declining in Misamis Oriental, impacting bat populations due to coastal and aquaculture development. This study evaluated the relationship between bats and mangroves. Mist netting was used to capture bat species, while quadrat sampling was used to sample mangrove species. Six different bat species have been identified and classified as least concern (LC) by the International Union for Conservation of Nature (IUCN). Cynopterus brachyotis was the most common bat species in all sampling locations, while Ptenochirus jagori, Eonycteris spelaea, and Harpyionycteris whiteheadi were first recorded in mangrove forests, adding to existing bat fauna literature in Mindanao. Cynopterus brachyotis is strongly associated with taller mangroves with larger diameter at breast height (DBH) and denser canopy cover based on canonical correspondence analysis (CCA). All the mangrove species found were classified as ‘Least Concern’ by the IUCN, except for Ceriops decandra, which were classified as ‘Near Threatened.’

Authors:   Institute of Africa of the Russian Academy of Sciences, Moscow, Russia, Gavrilova Nina G.
Published: January 2025

This article is devoted to determining the changing role of African countries in the production and export of a unique agricultural product - cocoa beans, which serves as a raw material for many industries. The production of this product has shifted from Latin American countries towards the African continent. Four countries - Côte d’Ivoire, Ghana, Nigeria and Cameroon - have been identified as the leading African producers of cocoa beans, which are also among the top ten world exporters of this product. It has been found that despite many differences in size, geography and economic situation, producer countries share common problems. Fundamentally, these are related to the small size of farms producing raw cocoa, the poverty of farmers, their technical and technological backwardness, insufficiently developed infrastructure, etc. However, in all aforementioned African countries, an agricultural policy has been developed and continues to be developed, which is aimed at increasing the living standards of farmers and improving the quality of raw cocoa materials to strengthen the country’s competitiveness in the world market. In the further development of the farmer support system, special attention must be paid to measures aimed at mitigating price shocks for immediate producers.

Published: January 2025

Toilet training in children is a crucial developmental milestone, focusing on teaching them to control defecation and urination. The absence of effective toilet training can result in several challenges, including social embarrassment when interacting with toilet-trained peers and increased stress and anxiety for both the child and parents. This study aims to evaluate the effectiveness of oral and modeling techniques in enhancing toilet training. Utilizing a case study design, we employed participatory observation, unstructured interviews, and documentation to gather data. The sample consisted of a pediatric patient aged 18-24 months. Data analysis was performed using domain analysis after tabulation. The findings indicate that employing oral and modeling techniques significantly improves toilet training outcomes in children. These methods are recommended for parents to implement in-home care settings to facilitate successful toilet training.

Honey healing: A sweet solution to alleviate diarrhea and curb bowel movement frequency in children
Authors: Qaromah Yafiana , Nugroho Sri Hananto Ponco , Sulistyono Dwi
Published: January 2025

Diarrhea is the second leading cause of death among children under five years of age. It can persist for an extended period, leading to dehydration and potential malnutrition. While the literature presents various complementary therapies for managing diarrhea, there is a notable lack of studies specifically addressing the use of honey to mitigate hyperactivity of bowel movements in affected patients. Therefore, the objective of this study was to evaluate the benefits of honey in children experiencing diarrhea. The study involved two pediatric patients who were administered pure honey over a two-day period. The dosage consisted of 5 cc of honey mixed with 10 cc of water, given three times daily at 07:00, 17:00, and 21:00. The honey used in the study was confirmed to be pure. The findings suggest that pure honey is effective in reducing the frequency of bowel movements in children with acute diarrhea. This conclusion is supported by the observed outcomes in both patients, which indicated a reduction in bowel movement frequency following the administration of honey. Consequently, it is recommended that pure honey be considered as a complementary treatment for children suffering from acute diarrhea.

Authors: Hidayanto Arif , Subrata Sumarno Adi , Widiyanto Puguh
Published: January 2025

Peptic ulcers are a leading cause of upper gastrointestinal bleeding, with the highest incidence observed among men and the elderly. Esophagogastroduodenoscopy (EGD) is the gold standard diagnostic tool, offering sensitivity and specificity rates of up to 90% for identifying peptic ulcers. This study aimed to describe the characteristics of peptic ulcer cases in patients presenting with hematemesis and/or melena who underwent EGD at RSUD Temanggung in 2023. A quantitative descriptive design was utilized, employing retrospective data collection from medical records of patients who met the inclusion and exclusion criteria. A total of 23 medical records were analyzed. Among the 23 cases of hematemesis and/or melena, peptic ulcers were the most common diagnosis, accounting for 47.8% (11 cases). Erosive gastritis was the second most common diagnosis (39.1%, 9 cases), followed by esophageal varices (13.0%, 3 cases). Of the 11 patients diagnosed with peptic ulcers, 63.6% were aged over 60 years, 27.3% were aged 40–59 years, and 9.1% were aged 19–39 years. Regarding gender, 81.8% of peptic ulcer patients were male, and 18.2% were female. The majority (90.9%) of patients had ulcers classified as Forrest III, while 9.1% were classified as Forrest IIc. The most common nursing problems identified included ineffective tissue perfusion (36.4%), nausea (36.4%), and pain (27.2%). The findings highlight that the majority of peptic ulcer cases involved Forrest III ulcers, and key nursing concerns included managing ineffective peripheral tissue perfusion and nausea. This study underscores the need for targeted interventions to address these common nursing problems and improve patient outcomes in peptic ulcer management.

Soft tissue augmentation using bone substitutes around dental implants healing abutments: a novel approach to enhance tissue width and quality
Authors: Hamad Shehab Ahmed , Xailani Kocher Kareem
Published: January 2025

Dental implants are widely recognized as a reliable solution for tooth replacement, with consistently high success rates. However, the pursuit of improved aesthetic outcomes and patient satisfaction has driven the advancement of techniques to enhance soft tissue stability around implants. This study investigated the effect of immediate implant placement combined with bone grafts and healing caps on soft tissue thickness and height. A prospective clinical study was conducted involving ten patients undergoing immediate tooth extraction and implant placement. A total of 18 implants were placed, with bone grafts applied around the implants and healing caps utilized. Gingival thickness and height were measured before tooth extraction and six months post-implantation using injection needles and transgingival probing methods. The results revealed significant increases in gingival dimensions after six months. The mean gingival height improved from 1.3 mm pre-extraction to 3.9 mm post-implantation, while the mean gingival thickness increased from 1.9 mm to 4.2 mm. The findings demonstrated stable gingival tissue and favorable aesthetic outcomes, underscoring the efficacy of immediate implant placement combined with bone grafts and healing caps. This approach significantly enhances soft tissue stability and aesthetics, providing a promising method for improving long-term implant success and patient satisfaction.

THE EFFECT OF PARTIAL REPLACEMENT OF CEMENT WITH FLY ASH ON THE STRENGTH OF CONCRETE FOR TRANSPORTATION STRUCTURES AND ROAD PAVEMENTS
Authors:   Odesa State Academy of Civil Engineering and Architecture, Kroviakov S.O. , Shymchenko P.V. ,   Odesa State Academy of Civil Engineering and Architecture
Published: January 2025

The effect of replacing part of the cement with fly ash on the strength of concrete for transportation structures and road pavements has been determined.
Portland cement CEM II/A-S 500, crushed stone (5–20 mm fraction), quartz sand with fineness modulus of 2.3, the superplasticizer Polyplast SP-1, and fly ash from the Darnytsia Thermal Power Plant were used in concrete production. The properties of three concrete compositions were investigated. Composition No. 1 (without fly ash) served as the control, with 300 kg/m³ of Portland cement used as the binder. In composition No. 2, 10% of the Portland cement was replaced with 75 kg/m³ of fly ash. In composition No. 3, 20% of the Portland cement was replaced with 150 kg/m³ of fly ash. All concrete compositions included 2.4 kg/m³ of superplasticizer.
All concrete mixtures exhibited equal workability (S1), with the water/cement ratio (W/C) depending on the composition. For the control composition No. 1, the W/C ratio was 0.390. For composition No. 2, the actual W/C ratio, calculated as the total binder content (cement and fly ash), was 0.333. For composition No. 3, the W/C ratio was 0.308. Thus, as the proportion of fly ash in the binder increased, the W/C ratio of the mixtures decreased.
The average density of the control concrete (composition No. 1) and composition No. 2 was approximately equal (2441 kg/m³ and 2446 kg/m³, respectively), while composition No. 3 exhibited a slightly lower density (2423 kg/m³). This can be explained by the fact that replacing part of the cement with a larger mass of fly ash reduces the W/C ratio while simultaneously increasing the spacing of coarse aggregates.
Compressive strength was measured at 7 and 28 days. At 7 days, the compressive strength of composition No. 2, where 30 kg/m³ of cement was replaced with 75 kg/m³ of fly ash, was 6.8% lower than that of the control (composition No. 1). However, at 28 days, the compressive strength of composition No. 2 was 3.8% higher than that of the control. For composition No. 3, replacing 60 kg/m³ of cement with 150 kg/m³ of fly ash resulted in a 28.3% decrease in compressive strength at 7 days and a 14.0% decrease at 28 days compared to the control. Thus, concretes containing fly ash demonstrated slower strength gain compared to concrete using only Portland cement as the binder. Replacing 10% of the Portland cement with a rational amount of fly ash produced concrete with strength comparable to that of the control composition. However, replacing 20% of the Portland cement was not fully compensated by the fly ash.
Therefore, the use of fly ash in concrete for transportation structures and road pavements is both feasible and effective. The introduction of a rational amount of fly ash reduces binder consumption, which has significant ecological benefits and is economically viable.

Authors:   King Danylo University, Luzhnyii S. , Zhyhaliuk S. ,   King Danylo University
Published: January 2025

The article explores the role of the «spirit of place» as an intangible factor in organizing urban spatial planning. It examines the significance of cultural heritage and national identity in shaping urban landscapes, describing how they foster a sense of belonging and attachment to a place. A method is proposed for integrating these factors into the urban planning process, enabling the creation of more sustainable and attractive urban spaces that resonate with historical and cultural contexts.
The concepts of «city spirit», «spiritual comfort», and «architectural code» are analyzed in detail, highlighting their features and interconnections. The «spirit of place» is considered a key element that shapes the unique identity of a location, influencing people's emotional perception and behavior. The importance of considering historical, cultural, religious, and social aspects in the formation of the architectural environment is emphasized.
Special attention is given to intangible aspects such as cultural heritage, traditions, folklore, and spirituality, which need to be integrated into urban planning decisions. This is particularly relevant in the context of post-war city reconstruction, where human needs, social cohesion, and the preservation of national identity should be prioritized.
Methods for using the «spirit of place» to create or transform architectural environments that consider the needs of different population groups and promote the preservation of cultural uniqueness are also proposed. An analysis of contemporary studies reveals the necessity of developing clear recommendations for implementing innovative solutions that take into account the ecological, socio-economic, political-legal, historical, and cultural characteristics of Ukrainian cities. Equally important is the creation of approaches for involving the public in the process of urban space transformation and modeling practical applications of the «spirit of place» concept in architectural design. Integrating these approaches will allow for the creation of comfortable urban spaces with high aesthetic and cultural value, contributing to the formation of a positive city ensemble and enhancing the quality of life for residents. The research emphasizes the importance of preserving historical memory, which will foster a deep sense of national belonging among the Ukrainian people.
The article proposes approaches that can form the basis for creating effective urban development strategies, taking into account the cultural and historical aspects that define the uniqueness of each place.

Published: January 2025

Background: Congenital heart disease (CHD) represents the most common and lethal birth defect affecting newborns. This study aimed to characterize the echocardiographic profile of CHDs, along with their prevalence and associated risk factors in CHD patients. Materials and Methods: This cross‐sectional, analytical study was conducted on CHD patients referred to the major pediatric hospital affiliated with Urmia University of Medical Sciences between March 2022 and October 2023. They were selected by convenience sampling method. The collected data, including mothers' parity, prior diagnoses of heart disease, hypertension, diabetes, thyroid disorders, COVID-19 infection during pregnancy, prior surgical procedures, use of complementary medicine during gestation, medication history, and mode of delivery. Additionally, child-related characteristics were investigated, including age, gender, co-existing congenital cardiovascular disease, neonatal intensive care unit (NICU) admission history, and echocardiographic findings. Specifically, the study focused on abnormalities in left ventricular fractional shortening (LVFS) and left ventricular ejection fraction (LVEF). Data analysis was done using SPSS software version 22.0. Results: Of 293 CHD children, 59.72% were male and 40.27% were female. Overall, 132 (45%) children were below one year of age. Among echocardiography profile, Patent Foramen Ovale (PFO) constituted 65 cases accounting for 22.1% of all CHD cases and Atrial septal defect (ASD) was the second most common CHD accounting for 16.3% of all CHD cases. Mother's infection with Covid-19 during pregnancy (P<0.001), type of delivery (P=0.015), and patient's NICU hospitalization (P=0.010) was statistically significant among the patients with normal and abnormal echocardiography. Conclusion: This study reveals a significant prevalence of Patent Foramen Ovale (PFO) and Atrial Septal Defect (ASD) among patients with congenital heart disease (CHD), highlighting the crucial role of early echocardiographic screening in this group. It also suggests a potential link between maternal COVID-19 infection during pregnancy, the method of delivery, and abnormal echocardiographic findings in CHD patients.

Authors: Chokami Rafiei Sahar , Jafary Nodoushan Zahra
Published: January 2025

Background: Adenomatoid odontogenic tumor is an asymptomatic, rare, benign neoplasm of odontogenic epithelium origin with a slow growth rate. Case Presentation: We describe a case of a 15-year-old male patient of Asian descent, who presented with a 0.8*0.8*0.3-cm expansile mass in the lateral incisor region, which is an uncommon location and gender for AOT. Cone-beam computed tomography revealed evidence of a well-defined unilocular radiolucent lesion in the anterior maxilla, with snowflake calcification, expansion of the buccal cortical plate, and lingual drift of the lateral incisor. After complete excision of the mass under local anesthesia and extraction of the associated tooth, the defect was filled with xenograft, covered with pedicle connective tissue graft from the palate, and sutured. Histological sections showed a benign odontogenic tumor composed of a proliferation of spindle-shaped epithelial cells forming strands and whorls structure. A thick capsule surrounded the lesion. Some basophilic calcification with concentric structures was also seen. A piece of oral mucosa covered by parakeratinized stratified squamous epithelium was evident. There was no evidence of malignancy. Conclusion: Clinical, radiographic, and histopathologic findings aided the final diagnosis of the AOT. The patient was treated surgically and later rehabilitated with a removable prosthesis. No recurrence was detected over the one-year follow-up. This study can help diagnose and manage this lesion according to its specific characteristics.

Published: January 2025

This case report presents the management of a patient suffering from severe facial asymmetry and malocclusion. The patient was born in 2001 and was later hospitalized due to severe jaundice. At 5 years of age, the deviation in the jaws and the post condylectomy ankylosis of the TMJ and hip joint problems were evident. At age 7, a costochondral graft was performed. In the next phase, orthodontic treatment was started with hybrid functional therapy, but the treatment was unsuccessful due to the severity of the problem. At age 15, bilateral distraction osteogenesis was performed. The orthodontic plan for the maxilla was non-extraction. We expanded the upper arch and corrected the crossbite of the lateral incisors. Due to the difficulty of surgery, the impacted canine of the mandible remained impacted. The mandibular right lower incisor was removed due to severe crowding. Orthognathic surgery was performed after fixed orthodontic treatment.

Authors: Shahraki Neda , Keikhaee Fatemeh , Kahnemuee Fatemeh
Published: January 2025

Background: The primary aim of this study was to compare palate depth and nasal septum deviation between patients with unilateral and bilateral buccal and palatal impactions of maxillary canines and those without impaction. Materials and Method: This cross-sectional study examined CBCT images of 60 patients from a private radiology archive, divided into four subgroups of 10 patients each with unilateral or bilateral buccal and palatal impactions, and a control group of 20 patients without impaction. Nasal deviation was assessed by measuring the distance of the maximum convexity of the deviated septum from the midsagittal plane in the coronal CBCT cut. Palate depth (PD) was measured as the perpendicular line from the middle of the axis connecting the mesiopalatal cusp of the first molar to the hard palate. Measurements were performed using NNT 16.3.1 software and validated by radiology and orthodontics specialists. Independent t-tests were used for statistical comparisons. Results: There were no significant differences in palate depth (p > 0.05) or nasal septum deviation (p > 0.05) between the control group and patients with unilateral or bilateral buccal and palatal impactions of maxillary canines. Conclusion: The study found no significant differences in palate depth and nasal septum deviation between patients with and without maxillary canine impaction, suggesting that impaction does not significantly affect these anatomical features. Further research is recommended to explore these findings in larger populations.

Published: January 2025

Background: This research aimed to evaluate the impact of Pulpine Mineral, Pulpine NE, and mineral trioxide aggregate (MTA) Angelus on crucial cellular functions, including viability, proliferation, attachment, and migration, in stem cells derived from human exfoliated deciduous teeth (SHEDs). Materials and Methods: In this laboratory-based investigation, SHEDs were exposed to 24-hour extracts from Pulpine Mineral, Pulpine NE, and MTA Angelus, prepared in both freshly mixed and fully set forms, over 24 and 72 hours. The methyl thiazolyl tetrazolium (MTT) assay was used to measure cell viability and proliferation, while a scratch test assessed the extent of cell migration. Scanning electron microscopy (SEM) provided insights into how these materials affected cell morphology and attachment. Data analysis was performed using one-way ANOVA and Tukey’s post-hoc test, with statistical significance set at α=0.05. Results: Among the materials tested, MTA resulted in significantly greater cell viability than the other groups (P<0.05). Interestingly, diluted extracts of set Pulpine Mineral showed comparable viability to MTA after 24 hours (P>0.05). In contrast, Pulpine NE yielded the lowest viability scores (P<0.05). For migration, the MTA group achieved complete scratch closure within 48 hours, whereas Pulpine Mineral facilitated partial migration but did not close the scratch entirely. Cells in the Pulpine NE group exhibited neither proliferation nor migration, as they were entirely non-viable. Conclusion: Pulpine Mineral showed superior biological effects compared to Pulpine NE; however, both Pulpine materials exhibited inferior results compared to MTA Angelus.

Published: January 2025

Background: Racial disparities in dental health care access have been a persistent issue in the United States. This study aims to investigate the association between racial disparities and access to dental care. Materials and Methods: This study conducted a secondary data analysis of the CHIS 2023 Adult Survey, which included a sample of 21671 individuals. The survey collected information on demographic characteristics, health behaviors, and dental health outcomes, including access to dental care. Ordinal regression analysis was performed to examine the association between racial disparities and dental service outcomes, controlling for demographic and socioeconomic factors. Results: The study found significant differences in demographic characteristics among racial groups. The 2023 CHIS analyzed 21,671 individuals across various racial groups, revealing significant variations in age distribution, with White individuals being the oldest and "Other single race" the youngest. Whites also had the highest median income and dental insurance coverage. An ordered logistic regression adjusted for age, gender, educational level, income last month, current smoking status, and dental insurance showed that being White was associated with a significantly higher number of dental visits (coefficient = 0.14, p-value = 0.005), while other racial groups did not show significant associations. Conclusion: This study suggests that racial disparities exist in dental service outcomes in California, with certain racial and ethnic groups being less likely to access dental care. The findings show the need to address these disparities and improve access to dental care for marginalized populations.

In this study, the relationship between HbA1c level and dental caries has been investigated to be a step towards increasing awareness and improving the health status and quality of life of diabetics. Materials and Methods: This cross-sectional study was carried out on  20 type 2 diabetic who referred to dental clinic of shiraz university of medical sciences between 2022 and 2023 and were separated into two categories of managed diabetes (HbA1c under 7%) and uncontrolled (HbA1c above 7%). The desired data were obtained through a questionnaire containing demographic information, clinical examination (DMFT (Decayed, Missing, Filled Teeth) index), oral hygiene, and carbohydrate consumption. Results: The average DMFT index is greater in individuals with unmanaged diabetes compared to those with Controlled Diabetes, though not statistically significant (P=0.137). However, as BMI increases, so does the DMFT index (P=0.035). There is no notable correlation between HbA1c levels and dental caries (P=0.2). Oral hygiene practices did not significantly affect the DMFT index (P=0.943). Carbohydrate intake per day did not impact the DMFT (P=0.34). Higher education levels were associated with a decrease in DMFT, though not statistically significant (P=0.172). Conclusion: Considering the higher rate of dental caries in individuals with uncontrolled diabetes, it is necessary to inform these patients about more oral and dental hygiene and blood sugar control.

Background: This study aimed to compare the dmft and oral health behavior of 7-9-year-old Iranian and Afghan children. Materials and Methods: This cross-sectional study was conducted on 87 Iranian and 70 Afghan children between 7-9 years, who were selected among elementary schoolchildren in Pishva, Iran by convenience sampling in 2023. The children underwent clinical dental examination by a dental explorer and a dental mirror under a head light to record their decayed, missed and filled teeth (dmft) index. Their oral health behavior was also evaluated by using a questionnaire completed by parents. Data were analyzed by the Chi-square test and Fisher’s exact test (alpha=0.05). Results: The dmft of Iranian children was significantly lower than of Afghan children (P<0.05). Also, Afghan children’s Oral health behavior. was lower than Iranian children (P<0.05) There was no significant difference between source of oral health information and toothbrushing technique between the two ethnic groups (P>0.05). Conclusion: Iranian 7-9-year-old children had lower dmft and superior oral health behavior than Afghan children, which highlights the effect of immigration and social and cultural factors on oral health behavior. Information drawn from this study can be helpful to design specific dental programms in order to provide better oral health for Afghan children.
Thermodynamic Model of Glass Ceramics Crystallization

The increase in the economic efficiency in many industries (energy, mineral resources, metallurgy, chemical coal, construction) is associated with new materials with unusual combination of physical, mechanical and chemical properties. Glass-ceramic materials obtained by directional glass crystallization rank first among others. Compared to crystalline substances, glass has increased internal energy (latent energy of crystallization). Therefore, the substance in the glassy state is metastable (thermodynamically unstable). Ordinary glass under certain conditions begins to crystallize, sometimes, spontaneously. This process is called drying or devitrification. A thermodynamic model is proposed based on the concept of dynamic equilibrium of energy and matter flows during phase transitions in non-equilibrium open systems. The model considers thermal force of the metasilicate crystal growth. Some of the main dependencies of kinetic parameters on thermodynamic properties are suggested for М2М1[Si2O6] metasilicate composition. The crystallization temperature growth occurs as the overall basicity ∆Ζо298 increases against relative increase in the basicity of ions in the cationic sublattice M2 and, especially, in the octahedral sublattice M1.

Negative consequences of global climate change and rapid urbanization are problems of combating urban floods, underflooding and increasing the safety of adjacent water bodies due to the washout of storm water and municipal waste. These problems are being solved slowly and ineffectively. This is explained by harsh climatic conditions in a large number of territories, higher number of abnormal rainfalls, insufficient financial injections into the construction of storm systems from the state and business structures, imperfection of regulatory documents based on outdated information for calculating projects. Conclusions are formulated on ways out of the crisis situation in the city of Tomsk (Western Siberia). It is proposed to improve the collection and drainage of atmospheric water from road sections.The relevance of the work is associated with the improvement of the system of atmospheric wastewater removal from the road pavement and urbanized areas, especially at abnormal volumes of rainwater.Purpose: The aim of the work is to assess environmental, economic and technological potential of Russian and foreign techniques to ensure effective storm water drainage and primary treatment of surface runoff.Methodology/approach: The analysis of the current state and prospects for the implementation of the best foreign practices for collecting, removing from urbanized areas, effective water drainage devices; comparative assessment of practices that are most suitable for continental climate conditions with a long cold period and significant amounts of precipitation; measures to improve the efficiency of storm water drainage; theoretical research of literary sources, theoretical analysis, interdisciplinary synthesis; methods of logical generalizations, patent analysis, search and statistical methods.Research findings: The paper highlights foreign achievements and problems of drainage and storm water treatment from urban roads. Increasing interest in biophilic engineering technologies includes stages of collection and removal of surface runoff water, its primary treatment, and evaporation or infiltration into deep aquifers. The state of the drainage problem in Russia is considered herein. Modern technical means capable of organizing a road drainage system and, if necessary, treating storm water are investigated. The main reasons for the unsatisfactory condition and insufficiency of road drainage systems are identified.Practical implications: Systematization and generalization of approaches to combating excess urban storm water serve as the basis for improving modern drainage systems in Russia. Foreign experience in draining, isolating, and recycling storm water can be used and developed in different natural and climatic zones of Russia with respect to the specifics of their geoecological situation.

Being one of the world's developing countries, Myanmar experiences a significant surge in bridge construction. It, however, suffers resource limits in the bridge sector, which may result in quality difficulties during the construction process. There are serious concerns with the maintenance of some Myanmar bridges, particularly the older ones. Some old bridges in Myanmar were built with limited time, materials, and they are currently in critical need of renovation. While the creation of new infrastructure plays an important role in Myanmar’s transport sector, maintenance of the existing bridge infrastructure is also necessary to ensure its continued safe development.This article presents a dynamic approach to integration of information and parametric modeling of revovation of steel truss bridges in Myanmar. A brief assessment is given for the current situation of steel truss bridges in Myanmar. The Grasshopper visual programming language is utilized for creating parametric scripts, and the model is able to integrate into information modeling tools such as Tekla Structures and Midas Civil for additional details and strength analysis. The integration of the truss parametric model into numerous software packages improves the flexibility of design automation process, saving time and effort. The design approach makes it possible to get several variants of the same model in a single file, and the process of building a complicated structure like a bridge becomes considerably simpler and more efficient. The results show significant improvements in time savings, alternative design selection, and structural performance. Furthermore, this approach has the potential to revolutionize bridge design, leading to more cost-effective and efficient structures that meet contemporary demands of the transportation infrastructure.
