The incidence of adenocarcinoma of oesophagus or gastro-oesophageal junction is increasing in Europe and other regions of the Western world. Research of possible causes has shifted to the molecular level. This study evaluated human papillomavirus (HPV) using real-time PCR and mutational status of selected genes using the multiparallel sequencing method (NGS) in DNA extracted from paraffin-embedded tumour tissue of 56 patients with oesophageal or gastro-oesophageal junction adenocarcinoma. The genetic material was in sufficient quality for the analysis in 37 cases (66 %). No HPVpositive sample was found. NGS revealed higher frequency of mutations in TP53, ARID1A, PIK3CA, SMAD4, ERBB2, MSH6, BRCA2, and RET genes. Association between gene mutations and histological grade, subtype according to Lauren, or primary tumour site was not statistically significant. In conclusion, the study did not confirm any HPV-positive sample of oesophageal and gastro-oesophageal junction adenocarcinoma. The study confirmed the usefulness of NGS analysis of paraffin-embedded tissue of these tumours, and it could be used in clinical studies to evaluate the prognostic and/or predictive value of the tested mutations. The association between gene mutations and histological features should be tested in larger patient cohorts.

The 2007 flora “Green Seaweeds of Britain and Ireland” did not present the molecular data underpinning the Ulvaceae treatment, mostly ITS sequences. Subsequently, names have changed as type material of Ulva species is sequenced and intensive sampling with DNA barcoding adds new European species. To update the Ulvaceae, we systematically sampled from 2007 to 2021, identifying specimens using various molecular markers alongside DNA from type material of four species. We show here that Ulva gigantea, based on rbcL, tufA and ITS sequences of its holotype, is assigned to Ulva compressa, as is the lectotype of Ulva curvata. Ulva gigantea sensu GenBank and Ulva pseudocurvata are conspecific. The correct name is U. pseudocurvata based on rbcL sequences of the lectotype. Two species of monostromatic Ulvaceae were included in the 2007 flora, but we show that both of them and all earlier British monostromatic collections represent Ulvaria splendens, a species originally described from Alaska. Analysis of two rbcL amplicons of the Ulva sordida lectotype shows that it is conspecific with Ulvaria splendens. Our first genuine collections of Ulvaria obscura from SW England and SW Wales correspond to topotype material from the Bay of Biscay, recent samples from Galicia and unpublished tufA sequences from Britanny.

The Lamiaceae family contains bioactive medicinal compounds mostly used as ornamental plants and traditional medicine, as well as in the food, cosmetics, and pharmaceutical sectors. Common uses include treating high cholesterol, diabetes, respiratory diseases, heart disease, and food poisoning. These medicinal uses were linked to their components and numerous biological properties, including antimicrobial and antioxidants. The goal of this study was to investigate the phytochemicals and biological activities of the petroleum ether extract of Thymus capitatus plant from two different regions of eastern Algeria (Souk ahras and Guelma), as well as to extract volatile oils using a Clevenger device and then analyze by using GC-MS. The results revealed that the total amount of phenolic compounds was better in the phenolic extract of Souk Ahras (3.41 mg GAE g−1), while the amount of flavonoid compounds was higher in the region of Guelma (26.31 mg QE g−1). Following the quantification of phenolic compounds by HPLC, we observed that the phenolic extracts contained most of the standard compounds in variable proportions. Furthermore, we tested the antioxidant activity of the phenolic compounds electrochemically with the cyclic voltammetry method. We concluded that the highest antioxidant content was recorded in the Guelma region extract (3.17 mg GAE g−1). We have also evaluated the antioxidant activity by a chemical method using 2,2-diphenyl-1-picrylhydrazyl, and the results showed that the Guelma extract exhibited a high effectiveness in terms of IC50% values. When extracting the volatile oils, it was found that the highest yield was in the Guelma region
Areas of stability of the dynamic equilibrium points of a chemical reactor
Authors: Berezowski Marek
Published: February 2024

This article develops a method for determining the areas of attraction of trajectories by stable points of dynamic equilibrium. This method is based on determining a line separating these areas. In the case of n-fold equilibrium states, there are a maximum of (n + 1)/2 regions of attraction. This is the maximum number of stable states. It may also happen that none of the states are stable and then there will not be any area of attraction. The number of all states n is odd. In the case of single stable states, we are dealing with one unlimited region of attraction. In the case of three-fold equilibrium states, two of which are stable, there are two regions of attraction, etc. In this study, the case of three-fold dynamic equilibrium states of a chemical tank reactor is considered.
The perfect waveguide coupler with universal impedance matching and transformation optics
Authors: Kim Myeongjin , Park Q-Han
Published: February 2024

Efficient energy transfer is crucial in electromagnetic communication. Therefore, producing a waveguide coupler that achieves broadband, nonreflective transmission is a challenging task. With the advancement of silicon-based integrated photonic circuits, fiber-to-chip coupling has become increasingly important. Although various couplers have been developed for fiber-to-chip coupling, they often have limitations such as long coupling length, low coupling efficiency, and narrow bandwidth. This is due to the inability to eliminate reflections between the two waveguides. Here, we introduce a method using universal impedance matching theory and transformation optics to eliminate reflections between two waveguides. The coupler, called the universal impedance matching coupler, using this method has the shortest subwavelength coupling length, a 99.9 % coupling efficiency, and a broad bandwidth.
Electrostatic self-assembly effect of Fe3O4 nanoparticles on performance of carbon nanotubes in cement-based materials
Authors: Wang Linghui , Ge Zhi , Zhang Ning , Feng Yujie , Ling Yifeng , Zhang Hongzhi
Published: February 2024

The beneficial effect of carbon nanotubes (CNTs) to enhance the electrical conductivity and piezoresistivity of cement-based materials was highly contingent upon its dispersion. To achieve an appropriate dispersion of CNTs, ultrasonication, high-speed stirring, and chemical dispersion were commonly used, which raises the risk of structural damage of CNTs caused by the excessive energy. In this study, electrostatic self-assembly of Fe3O4 nanoparticles on CNTs was employed to efficiently disperse CNTs. To optimize the dispersion effect of conductive fillers in cement paste, the mix proportions including sodium dodecyl sulfate (SDS) concentration, CNTs concentration, and Fe3O4/CNTs ratios were adjusted. The dispersion degree and electrical property were evaluated by UV–vis absorption and zeta potential. In addition, the effect of self-assembled conductive filler dosage on the electrically conductive property of cement pastes was examined. The results show that the occurrence of electrostatic self-assembly was proved by the change of zeta potential, and the grape-bunch structure was observed by transmission electron microscopy. Further, the optimal proportions of self-assembled conductive fillers were 0.20 wt% SDS concentration, 0.05 wt% CNTs concentration, and 1:1 Fe3O4/CNTs ratio. The self-assembled conductive filler dosage between 0.02 and 0.10 wt% can effectively improve the electrical conductivity of cement paste with up to 68% reduction of resistivity.

Authors: Zhang Peng , Su Jia , Gao Zhen , Zhang Tianhang , Zhang Peng
Published: February 2024

The geopolymer mortar (GPM) prepared from industrial by-products and alkali activation solution (AAS) is one of the hot spots of current building materials. As a feasible alternative to natural river sand, manufactured sand (MS) alleviates the global ecological pressure. In this study, MS was used for fine aggregate. Sodium hydroxide (NaOH) and sodium silicate (Na2SiO3) solution were used as AAS. Metakaolin (MK) and fly ash (FA) were used as the precursor to prepare MK-FA-based GPM with MS (MS-GPM), which was of great significance for saving non-renewable resources, mitigating the greenhouse effect, and recycling waste. Numerous studies were conducted to explore the effect of sand–precursor ratio (r
sp) on mechanical and durability characteristics of MS-GPM. Relationships between compressive strength and tensile or flexural strength were established by linear fitting equation. Finally, analysis of variance (ANOVA) was used to systematically calculate the effect of r
sp on performance. The results indicated that the mechanical strength and impermeability of MS-GPM decreased and crack resistance increased with r
sp from 1 to 5. The strength of MS-GPM was the best when r
sp was 1. With the increase of r
sp, the proportion of MS in MS-GPM increases, and the relative cementitious material decreases, which has an adverse impact on mechanical properties and impermeability. Linear fitting revealed that the compressive strength of MS-GPM was closely related to tensile strength and flexural strength. ANOVA results indicated that r
sp in the range of 1–5 had great effects on the performance of MS-GPM. The aim of this article is to further promote the possibility of applying MS-GPM in practical engineering by designing reasonable r
sp.

Authors: Heinrichs Peter , Stammler Hans-Georg , Mitzel Norbert W.
Published: February 2024

The reaction of chlorodimethylphosphane with dilithiated bis(ethynyldimethylsilyl)methane leads to the corresponding bis[(dimethylphosphanylethynyl)dimethylsilyl]methane (1) which reacts readily with chloroauric acid in the presence of a reductant to form its dinuclear chlorogold(I) complex (2). The terminal chloride units of this compound can be substituted by reaction with nucleophiles. Furthermore, the metallophilic host functionality of the dinuclear complex 2 towards metallophilic atoms such as copper, silver, and thallium was tested. The crystal structure of bis[(dimethylphosphanylethynyl)dimethylsilyl]methane-digold(I) dichloride (2) is presented, which shows chains of the molecules aggregated by intermolecular aurophilic contacts.

Temperature Index of Electrical Insulations by mTGA
Authors: Xu James J. , Kaminski Christopher A.
Published: February 2024

Temperature index (TI) is a common measure for the temperature classification of electrical insulation materials (EIMs) used in electric machines and apparatus. TI is generally obtained through accelerated life testing lasting >7–8 months at certified labs. This paper deals with a new life-testing method to determine TI using thermogravimetric analysis (TGA), more particularly, modulated TGA (mTGA), The method of estimating precision of the TI is also given. The testing time may be reduced to <15 h per test. The new concept simplifies the life equation for practicability. The new method is not a replacement of conventional life testing, but may be of particular utility for screening new EIMs and evaluating materials with a known TI, after minor changes in composition have been introduced to improve physical properties. It can be a recommended method once it has been verified over a suitable range of EIMs.
Grey and white matter metrics demonstrate distinct and complementary prediction of differences in cognitive performance in children: Findings from ABCD (N= 11 876)
Authors: Michel Lea C. , McCormick Ethan M. , Kievit Rogier A.
Published: February 2024

Individual differences in cognitive performance in childhood are a key predictor of significant life outcomes such as educational attainment and mental health. Differences in cognitive ability are governed in part by variations in brain structure. However, studies commonly focus on either grey or white matter metrics in humans, leaving open the key question as to whether grey or white matter microstructure play distinct or complementary roles supporting cognitive performance.

To compare the role of grey and white matter in supporting cognitive performance, we used regularized structural equation models to predict cognitive performance with grey and white matter measures. Specifically, we compared how grey matter (volume, cortical thickness and surface area) and white matter measures (volume, fractional anisotropy and mean diffusivity) predicted individual differences in cognitive performance. The models were tested in 11,876 children (ABCD Study, 5680 female; 6196 male) at 10 years old.

We found that grey and white matter metrics bring partly non-overlapping information to predict cognitive performance. The models with only grey or white matter explained respectively 15.4% and 12.4% of the variance in cognitive performance, while the combined model explained 19.0%. Zooming in we additionally found that different metrics within grey and white matter had different predictive power, and that the tracts/regions that were most predictive of cognitive performance differed across metric.

These results show that studies focusing on a single metric in either grey or white matter to study the link between brain structure and cognitive performance are missing a key part of the equation.

Significance StatementThis paper enriches the recent debates on the challenges of linking variation in brain structure to phenotypic differences (Marek et al., 2022). We demonstrate that using latent variables (to improve power), structural equation modelling (to allow greater flexibility in linking brain to behaviour), and by simultaneously incorporating multiple measures of grey and white matter in a large sample, we demonstrate relatively strong and robust brain-behaviour associations, which highlight the complementarity of grey and white matter metrics in predicting cognitive performance as well as the importance of incorporating the full complexity of these associations over 1-to-1 linkages. This finding should lead researchers to consider integrating both grey and white matter measures when demonstrating a more comprehensive picture of brain-cognition relationships.
Spindle shape and volume differ in high- and low-quality metaphase II oocytes
Authors: Fluks Monika , Milewski Robert , Tamborski Szymon , Szkulmowski Maciej , Ajduk Anna
Published: February 2024

In brief

Optical coherence microscopy non-invasively visualizes metaphase II spindles allowing for quantitative analysis of their volume and shape, which may prove useful in the assessment of the oocyte quality. Using a mouse model, we showed also that analysis of spindle length combined with morphokinetics improves the evaluation of the resulting embryos.

The proper development of embryos strongly depends on the quality of oocytes, so the evaluation of oocytes may be a useful initial step in IVF procedures. Additionally, it enables embryologists to make more informed decisions regarding the treatments chosen for the patients and better manage patients’ expectations. Optical coherence microscopy (OCM) allows for non-invasive 3D visualization of intracellular structures, such as spindles or nuclei, which have been linked to the success of embryonic development. Here, we applied a mouse model to examine whether OCM imaging could be used in the quality assessment of metaphase II (MII) oocytes. We showed that quantitative parameters describing the shape and volume of the MII spindle were associated with the quality of the resulting embryos, including the likelihood of blastocyst formation and the embryos’ ability to differentiate the trophectoderm and primitive endoderm, but not the epiblast. We also created a multivariate linear regression model, combining OCM-based quantification of MII spindles with morphokinetic analysis of the embryos, that allowed for improved evaluation of the embryo quality. Finally, we proved that OCM does not interfere with the viability of the scanned cells, at least during the preimplantation development. Therefore, we believe that OCM-based quantitative assessment of MII spindles can improve the oocyte and embryo selection in IVF procedures.
Interference with the activities of a defense counsel or representative of a person: criminal law and criminology dimension.
Authors: Balobanova D.O.
Published: February 2024

The article analyzes the criminal law and criminological characteristics of the criminal offense under Article 397 of the Criminal Code of Ukraine. The author notes that this criminal offense has a complex structure of the direct object, since interference with the activities of a defense counsel impedes not only the exercise of a person’s right to defense, but also the right to legal aid, and on this basis the author suggests that the direct object of interference with the activities of a defense counsel should be social relations which exist in connection with the activities, performance of duties and ensuring the rights and legitimate interests of certain subjects.The author points out that from the objective side, the criminal offense under study is expressed in any form of interference with the lawful activities of a defense counsel or a person’s representative in providing legal aid or violation of the guarantees of their activities and professional secrecy established by law. It is assumed that this encroachment is possible only in the case of an intentional form of guilt with the aim of obstructing, changing or terminating the provision of legal aid, and this direction of criminalized activity is the purpose of this offense.The article analyzes certain official statistics on criminal offenses in the area of interference with the activities of a defense counsel, attorney or representative of a person and the results of their investigation, which determine the existence of problems in this area for the period from 2015 to June 2023 includive. It is proven that the mechanism for protecting the professional activity of defenders (lawyers) in Ukraine is ineffective, which significantly reduces the possibilities for effective protection of the rights and freedoms of citizens and public interests. The identified issues require larger-scale scientific research with appropriate justification and the development of more effective mechanisms to protect the activities of defenders (lawyers) and representatives of the person.
Liability for Unlawful Correction of Justice: Historical Genesis of National Criminal Law
Authors: Pulyk V.M.
Published: February 2024

The article examines the historical genesis of national criminal legislation in terms of regulating liability for interference with the judiciary. The author analyzes the legal monuments of Kievan Rus, the Grand Duchy of Lithuania, the Commonwealth of Poland, the Russian Empire, the Soviet era and independent Ukraine – the current Criminal Code of 2001 and its current draft created in the course of reforming criminal legislation. In the process of developing a model for periodization of criminal law protection of judicial independence and judicial activity in Ukraine, the author proposes to apply a mixed criterion based on the validity, legal force and level of codification of a legal instrument containing criminal law provisions on interference with the activities of judicial bodies, and also takes into account the historical stages of formation of Ukrainian Statehood. The author identifies the stages of development of criminal legislation in this area: Stage I (XI - XV centuries) – the origins of criminal law policy in the field of protection against interference with the activities of judicial authorities and persons entrusted with the administration of justice; Stage II (XVI - XIX centuries) – the formation of criminal law policy in the field of protection against interference with the activities of judicial authorities and persons entrusted with the administration of justice; III stage (early twentieth century - adoption of the Criminal Code of Ukraine in 2001) – fixation of the content of unlawful behavior within the criminal law policy of ensuring protection against interference with the activities of judicial authorities and persons entrusted with the administration of justice, which corresponds to the current provision of Article 376 of the Criminal Code; IV stage (late twentieth century - to the present) – further improvement of the criminal law policy in the area of ensuring protection against interference with the activities of judicial authorities and persons entrusted with the administration of justice.

Published: February 2024

Straw pretreatment enhances the cellulose accessibility and increases the methane yield from anaerobic digestion. This study investigated the effects of alkali pretreatments with different chemical agents (NaOH, KOH, and Na2CO3) on the physicochemical and thermal characteristics of barley straw, as well as methane production from codigestion with sewage sludge. Artificial neural network modeling with a feedforward neural network (FFNN) and slime mold optimization (SMO) techniques were used to predict methane production. NaOH pretreatment was shown to be the best pretreatment for removing hemicellulose and lignin and for increasing the cellulose accessibility. Moreover, there was a 2.57-fold higher level of methane production compared to that from codigestion with untreated straw. The removal ratios for the total solids, volatile solids, and chemical oxygen demand reached 59.3, 67.2, and 73.4%, respectively. The modeling results showed that the FFNN-SMO method can be an effective tool for simulating the methane generation process, since training, validating, and testing produced very high correlation coefficients. The FFNN-SMO accurately predicted the amount of methane produced, with an R2 of 0.998 and a 3.1×10-5 root mean square error (RMSE).

The aim of the present study was to develop the first life tables for the domestic feline population of the Autonomous City of Buenos Aires by constructing general cohort tables. To develop the life tables, data from felines received for final disposition at the Luis Pasteur Zoonosis Institute of the city from January 2018 to December 2021 were used. Of the 7945 cats that died in that period, the overall life expectancy at birth was 11.01 years (95% CI=10.55- 11.46 years). When life expectancy was analyzed according to sex, significant differences were found, being higher in females, 12.26 years (95% CI: 11.78- 12.73) than in males, 10.92 years (95% CI: 10.50- 11.35). According to neutered status, life expectancy at birth in the neutered, 13.19 years, was significantly higher than in the entire, 5.55 years (p-value=0.00001). Likewise, life expectancy among purebred cats was significantly higher, 14.81 years (95% CI: 14.51- 15.10), than for cross breed cats, 10.97 years (CI: 10.81- 11.13). Regarding the variations in mortality according to the warm or cold season of the year, no differences were observed between the two seasons. The most prevalent causes of death were related to urinary system failures and neoplasms, over 444 records analyzed. This study provides useful information for veterinary professionals and pet owners and is a valuable tool for the planning and development of effective health policies.

Authors: Alina Pikhtirova , Kiełb Ewa Pecka , František Zigo
Published: February 2024

The resistance of pathogenic microorganisms to antibiotics has become a "scourge" of the medical field in recent decades. In this regard, the vector of medical research rightly changed in favor of the search for natural mechanisms to fight pathogens. Nature has produced mechanisms for maintaining balance for millions of years, so it is reasonable to investigate and, in the future, use such mechanisms. This current study reviews and analyzes the last five years of research on the effects of saponin-containing plants on the most common pathogens. The analysis of literary data confirms the growing interest in natural antimicrobial drugs that are currently used in folk medicine or have the prospect of use in humane medicine in different countries of the world. Wide interest of the scientific community in the search for alternative antimicrobial agents, which would make it possible to overcome antibiotic resistance in the treatment of various types of diseases, has been revealed. Current scientific research has confirmed or disproved the effectiveness of only a thousandth part of all possible plants. Undoubtedly, the use of natural plant components will make it possible to make the treatment process cheaper and more effective, so this direction of research is currently very promising from all points of view.
Fungal diversity in environments of repository of the national archive of the Republic of Cuba from the 80s to 2022
Authors: Borrego Sofia
Published: February 2024

This work aims to perform a compilation of the fungal diversity in the environment of the National Archive of the Republic of Cuba (NARC) repositories from the 80s of the last century and until 2022, which includes the fungal genera and species isolated from: air, settled dust and document surface, as ecological niches that contribute to the environmental mycological quality of these spaces in the institution. A total of 55 references were analyzed (31 of air, 4 of settled dust and 20 of different types of documents surface). A total of 168 fungal genera and 54 species were isolated from air, 36 genera and 12 species from dust as well as 98 genera and 26 species were detected on the document surfaces with a marked predominance of the genera Aspergillus, Cladosporium and Penicillium in the three niches, although 24 rare genera were detected in air after the year 2000 (e.g. Acremonium, Aureobasidium, Beltraniella, Bipolaris, Blastomyces, Botryoderma, Botryotrichum, Chaetomium, Chrysonilia, Exophiala, Gilmaniella, Harposporium, Hyalodendriella, Itersonilia, Nodulisporium, Ovulariopsis, Papularia, Scolecobasidium, Sepedonium, Sprorobolomyces, Torula, Trichophyton, Wardomyces, Zygosporium). Only six genera were similarly isolated from air, dust and the document surfaces (9.7%), while 19 species were found in these three niches (9.5%) (e.g. A. flavus, A. niger, A. versicolor, Cl. caryigenum, Cl. cladosporioides, Cl. herbarum, P. chrysogenum, P. citrinum, P. commune, P. janczewskii). Although fungal isolations from dust and the document surfaces are still scarce, it is evident that the greatest diversity of species was isolated from the air and that the similarities of species between these three niches are low, therefore air is the matrix that contributes with the most fungal species to the NARC environment. This compilation of the fungal diversity in the environment of the NARC repositories will serve as a reference for future studies in Cuban archives and other countries.

Published: February 2024

Children experiencing homelessness (CEH) have several health-related needs. It is necessary to address barriers posed by homelessness to improve health outcomes. Our objectives were to (1) conduct a health-related needs assessment and (2) determine acceptability/feasibility of the community-based initiative designed to identify and address health-related needs for CEH. The initiative involved a mobile care center, a health-focused education series for CEH, and resource provision, which included establishing connections with a stable source of health care. The needs assessment included standardized screening questions assessing health-related needs. We surveyed guardians of CEH who attended Summer360 between June and July 2022. Guardians were invited to evaluate our intervention via survey. We used descriptive statistics to characterize health-related needs. A needs assessment was completed on 36 of 100 children (42% white persons, 64% male), with 94% reporting at least 1 health-related need, and 61% with ≥3 needs. The most common needs identified were dental health and food insecurity. Twenty-four (24%) campers participated in a mobile health clinic that included hearing and vision screening, fluoride application, and vaccinations. The education series included dental hygiene, nutrition, and mental health. All families who desired assistance (73%) were connected to resources, and 91% of guardians agreed that the initiative helped meet their children’s health-related needs and provided helpful resources. Implementation required planning with contributors including dental partners, mobile clinic operators, and school leadership. A community-based health initiative may serve as a unique opportunity to identify and address health-related needs for CEH.

A new species, Telipogon pillaropatatensis, is described from the highlands of east-central Ecuador. It is morphologically similar to T. octavioi but differs by having a corolla with longitudinal thick vein lines without reticulations and a column with three dense bundles of equally sized setae. Also, our phylogenetic analyses suggest that they are not closely related. Interestingly, among the analyzed taxa, T. pillaropatatensis appears to have a closer phylogenetic relationship with the highly distinct T. pulcher and T. hausmannianus than with the morphologically similar T. octavioi. The new species has been found in a relatively small area, covering just a few square kilometers in east-central Ecuador. Additionally, we documented remarkable variation in the coloration and size of the corolla. Information regarding the species' habitat, ecology, phylogenetic relationships, and conservation status is also provided.

The article considers the identification of potential sources of formation of water and mudflows in the area of the Olympic objects of the southern slope of the Psekhako ridge and the catchment areas of the 1st, 2nd and 3rd Galion rivers (the catchment area of the Mzymta river). The collection and study of natural, climatic and morphological characteristics mudflow basins and the study of the possibility of their negative impact on the operated Olympic facilities, the creation of a database of mudflow basins. Implementation of the results of studies of the natural-climatic and morphological characteristics of the mudflow basin of the river. Mzymta is assumed in the justification of anti-mudflow measures to protect the infrastructure of operated Olympic facilities from the negative impact of water and mudflows. To ensure the reliability of the functioning of these foundations and foundations of structures. It is important to take into account the possibility of a negative impact on them of water and mudflows that form in the conditions of mountainous terrain and natural and climatic features of this region, as well as due to the extremely insufficient knowledge of the current state of development in these territories. mudflow processes and the possibility of their activation as a result of the impact on the natural landscapes of mudflow basins during the operation of the foundations and foundations of Olympic facilities and their infrastructure (access and technological roads, power lines, ski slopes, chairlifts, various sites, etc.). Taking into account the impact of the consequences of a large-scale technogenic impact on the natural landscape, in the territory of operation of the Olympic facilities along the southern slope of the Psekhako ridge, the materials of the survey confirm the conclusions about the increased mudflow hazard of the watercourses of the river. Rudnichny, r. Sumasshedshiy, r. Kamburovsky. The main reason for the descent of these mudflows is the technogenic impact on the upstream natural landscapes, including the discharge of liquefied soil dumps from steep slopes, the concentration of surface runoff into concentrated eroded, cuts, etc. Simulation modeling of the stability of the river slopes was performed. Tobias, the most dangerous combinations of impacts under static and seismic conditions, to predict the formation of mudflows.

This article is aimed at studying methods for optimizing the pile field in order to ensure the greatest use of the bearing capacity of piles, adopted in the project, considering the most unfavorable design combinations of forces. The object of the study is a multi-storey apartment building on a slab-pile foundation with a regular grid of piles, which clearly shows the imperfection of the calculation methods, due to the incomplete use of the bearing capacity of a significant number of piles, but the methods described in the article are also applicable to other buildings on slab-pile foundations, especially the difference between the original scheme and the optimized scheme will be clearly visible on the example with longer piles in less bearing soils, spread over the entire depth of the foundation. The purpose of this study is to study methods for optimizing a pile field, to study the methodology for using these methods on a specific example and compare them in terms of the parameters of using the bearing capacity of piles: the absolute and relative value of the minimum load on the pile, the absolute and relative value of the maximum load on the pile, the absolute and relative value average load per pile, as well as their comparison of economic efficiency. In the course of the article, numerical modeling was used, using the finite element method and analysis of the results of multivariate calculation. The result of this article is the application of pile field optimization methods to the multi-storey building on a slab-pile foundation, the evaluation of each of the methods and their comparison according to these indicators, as well as an understanding of the further development of this topic.
Evaluation of the effectiveness of the use of indicator methods in determining the carbonization of concrete

Currently, one of the most important problems is the impact of aggressive environments on reinforced concrete structures, as a result of which the process of their destruction is triggered. One of the reasons for the failure of reinforced concrete structures is the process of carbonization of concrete. In practice, in order to timely eliminate and prevent the problem of carbonization of concrete, an indicator method for determining damaged zones is used. However, the traditional phenolphthalein test method does not allow to determine with high accuracy the boundary zones of concrete that are most vulnerable to carbonization. The article discusses the possibility of improving the phenolphthalein test method by using additional solutions of acid-base indicators alizarin and neutral red. The results of experiments on measuring the surface neutralized layer of concrete with alcohol solutions of acid-base indicators alizarin and neutral red on concrete samples of various ages and sizes are presented. The results of a comparative analysis of the traditional and improved methods for determining the carbonization of concrete are presented. The method proposed by the authors is distinguished by greater accuracy of the results obtained. The solution of neutral red expands the boundaries of the application of the phenolphthalein test method for determining the carbonization zones of concrete at 6 < pH < 10.5. The use of alizarin in addition to the phenolphthalein solution is difficult because the indicator solution is too dull in color, resulting in the definition of zones of highly alkaline concrete not being accurate enough. Due to the fact that the phenolphthalein test method has limitations in its use by examiners at the field stage, it is advisable to continue the search for indicators that can supplement or fully replace phenolphthalein for these purposes.

In the conditions of global warming of the climate in the territories of permafrost distribution it takes place the processes of increasing the temperature of perpetually frozen soils and increasing the depth of their thawing. These factors lead to a decrease in the structural safety of the buildings and constructions. Measures to return soils to the frozen state are not always feasible and effective. In such conditions the solution to the problem of decreasing the pile foundation bearing capacity can be the ground strengthening by the cementation using the wristband-pipe injection technology. In the article it is presented the experience of assessing the current technical condition and designing of bases and foundations strengthening of a three-storey residential building in Yamal-Nenets Autonomous District, village Muzhi. The object was given a limited-operational category of the technical condition due to the deficit of the pile foundation bearing capacity. To bring the constructions of the object to the working condition the project of pile foundation strengthening with the cementation by wristband-pipe injection technology was developed. While injecting the soil foundation with the hydraulic fracturing the additional (induced) tension state appears, and it changes the deformation and strength properties of soils, voids ratio, index of liquidity and modulus of deformation. Reinforced joints, soil compaction and stabilization appear due to the injection. While making the hydraulic test and fracturing in the soil body its stress and strain state is changing, foundation piles are stressed with the additional lateral pressure. Besides the soil is strengthening under the pile toe bulb. Analytical calculations are given for increasing the bearing capacity of a pile during cementation of soils due to the increase of horizontal stresses and the work of compacted foundation soil on the lateral surface and under the lower end of the pile.
