The epithelial cells that line the kidneys and lower urinary tract are exposed to mechanical forces including shear stress and wall tension; however, the mechanosensors that detect and respond to these stimuli remain obscure. Candidates include the OSCA/TMEM63 family of ion channels, which can function as mechanosensors and osmosensors. Using Tmem63bHA‐fl/HA‐fl reporter mice, we assessed the localization of HA‐tagged‐TMEM63B within the urinary tract by immunofluorescence coupled with confocal microscopy. In the kidneys, HA‐TMEM63B was expressed by proximal tubule epithelial cells, by the intercalated cells of the collecting duct, and by the epithelial cells lining the thick ascending limb of the medulla. In the urinary tract, HA‐TMEM63B was expressed by the urothelium lining the renal pelvis, ureters, bladder, and urethra. HA‐TMEM63B was also expressed in closely allied organs including the epithelial cells lining the seminal vesicles, vas deferens, and lateral prostate glands of male mice and the vaginal epithelium of female mice. Our studies reveal that TMEM63B is expressed by subsets of kidney and lower urinary tract epithelial cells, which we hypothesize are sites of TMEM63B mechanosensation or osmosensation, or both.
On maximal totally real embeddings
Authors: Pali Nefton
Published: May 2024

We consider complex structures with totally real zero section of the tangent bundle. We assume that the complex structure tensor is real-analytic along the fibers of the tangent bundle. This assumption is quite natural in view of a well-known result by Bruhat and Whitney. We provide explicit integrability equations for such complex structures in terms of the fiberwise Taylor expansion. In a particular geometric case considered in the literature, we explicit much further the fiberwise Taylor expansion of the complex structure as well as the integrability equations.

Published: May 2024

Objectives

Digit ratio (2D:4D), as endocrine fingerprint, can indicate prenatal androgen exposure. It serves as an anatomical marker for various systemic diseases and a few studies relating it to oral health. The present study aims to evaluate the association between digit ratio and susceptibility to dental plaque formation.

Methods

The study was conducted on young adults aged between 18 and 25 years. Digit ratio and reproductive hormones were measured; dental plaque score and gingival index (GI) were recorded. Data were analysed using the MedCalc. v.20.

Results

Male and female participants were categorized into two groups based on their digit ratios being either above or below the calculated average (0.99 for females, 0.98 for males). Those with a digit ratio below the average had a significantly higher mean dental plaque score (p < 0.0001) than those with ratios at or above the average. However, there was no significant difference in the GI between the two groups. Reproductive hormone profiles varied significantly between the higher and lower digit ratio groups for both sexes.

Conclusions

Digit ratio may find potential to be used as an anatomical marker to identify the susceptibility to dental plaque build-up.

Published: May 2024

Objectives

To evaluate medical students’ knowledge, attitudes, and self-medication practices for acne vulgaris.

Methods

An analytical cross-sectional study was conducted at Beni-Suef University’s Faculty of Medicine from January 2023 to June 2023. A pre-structured questionnaire was used for the study.

Results

A total of 297 students (85.1 %) used self-medications for acne without a prescription. The total knowledge score of self-medication among the study participants was 3.81 ± 2.23. About 71.4 % knew about precautions, and 72.7 % of the participants reported that self-medication is part of self-care. There was a statistical significance between the total mean knowledge score and age (p=0.007), gender (p=0.013), and academic year (p=0.001).

Conclusions

A significant portion of students self-medicate about acne. The total knowledge score of self-medication was to some extent not relatively high. Educational programs can be developed to increase medical students’ awareness of the risks and benefits of self-medication, information on appropriate use of medications, and when to seek medical attention.
The salience of students’ body language during in-person and online lectures at a Canadian university
Authors: Salvato Giuliana
Published: May 2024

Professors teaching different disciplines at a university in Canada received an email invitation to fill-out an online questionnaire where they could reflect on and express their opinions about the pedagogical and communicative roles of the body during their lectures. The questionnaire was divided into two parts: one asking professors to comment on their own body language; the other inquiring about professors’ perception of their students’ body language usage. This article is specifically focused on the second part of the survey, where professors reacted to questions concerning awareness of students’ body language during classes held in-person and online. In investigating the perceived salient functions attributed to students’ body language, this study values multimodal competence, embodied communication, and it informs the concept of immediacy in the relationship between students and professors at the university level.
Elevated mRNA level indicates FSIP1 promotes EMT and gastric cancer progression by regulating fibroblasts in tumor microenvironment

Published: May 2024

Fiber sheath interaction protein 1 (FSIP1) plays a crucial role in cancer development and occurrence, but its influence on gastric cancer is still unclear. In this study, differential mRNA analysis was performed by TCGA database for the Limma analysis algorithm, and the gene ontology, the Kyoto Encyclopedia of Genes and Genomes, and the gene set enrichment analysis (GSEA) were used for bioinformatics functional enrichment analysis. A gastric cancer cell model with FSIP1 mRNA knockdown was constructed by RNA interference. Cell counting kit-8 and transwell migration/invasion assay were performed to verify the cell function, and western blotting was employed to confirm the expression of target genes. The GSEA analysis revealed that FSIP1 was associated with epithelial-mesenchymal transition (EMT). The high expression group also had a significant positive correlation with the markers of fibroblast in tumor microenvironment (TME). Western blotting showed that FSIP1 was generally upregulated in gastric cancer cell lines. FSIP1 mRNA knockdown cell lines inhibited gastric cells proliferation, migration, and metastasis in vitro, and the protein levels of EMT-related markers N-cadherin and vimentin were reduced. Our work proved that FSIP1 promoted EMT by regulating fibroblasts in the TME, thereby promoting the carcinogenic activity of cancer cells in proliferation, invasion, and migration. FSIP1 may take a role of the occurrence and could be a potential therapeutic target and offer a new insight into the underlying mechanism of gastric cancer.

Published: May 2024

Objectives

In this study, the aim is to provide a more detailed understanding of vitamin D metabolism by evaluating the correlation between 1,25-dihydroxyvitamin D (1,25(OH)2D) and 25-hydroxyvitamin D (25(OH)D) according to the variations in measurement methods and clinical conditions.

Methods

We searched PubMed, Embase, and Web of Science for studies reporting correlation results between 1,25(OH)2D and 25(OH)D. We performed a meta-analysis based on the correlation results of 1,25(OH)2D and 25(OH)D in different clinical conditions. We included a total of 63 studies and our laboratory’s results in the meta-analysis. The studies were categorized into high-quality methods group (HQMG), medium-quality methods group (MQMG), and low-quality methods group (LQMG) based on the 25(OH)D and 1,25(OH)2D measurement.

Results

In the healthy, renal disease, and other disease groups, the highest correlation values were observed in the studies categorized as HQMG, with values of 0.35 (95 % CI; 0.23–0.48), 0.36 (95 % CI; 0.26–0.42), and 0.36 (95 % CI; 0.22–0.48), respectively. Significant statistical heterogeneity was observed in the healthy, renal disease, and other disease groups, with I2 values of 92.4 , 82.7, and 90.7 %, respectively (p<0.001). Both Funnel plots and the results of Egger’s and Begg’s tests indicated no statistically significant bias across all studies.

Conclusions

A significantly low correlation was found between 25(OH)D and 1,25(OH)2D. However, higher correlations were found in the studies categorized as HQMG. Various factors, including methodological inadequacies and disparities, might contribute to this. In the future, with more accurate and reproducible measurements of 1,25(OH)2D, a clearer understanding of vitamin D metabolism will be achieved.
Gletschertourismus ohne Eis? Die Transformation und Positionierung von alpinen Gletschertourismus-Standorten in Zeiten des Klimawandels

Published: May 2024

Der Klimawandel führt zu einem noch nie dagewesenen Gletscherschwund in den Alpen. Daher analysiert dieser Beitrag, wie BesucherInnen von Gletschertourismusstandorten diesen Landschaftswandel wahrnehmen und wie sich diese Standorte positionieren könnten, wenn ihre Hauptattraktionen verschwinden. Konzeptionell verknüpfen wir den wissenschaftlichen Diskurs über den Last Chance Tourism (LCT) mit Positionierung und den touristischen Attraktionssystemen von Leiper. Wir befragten die BesucherInnen von sechs alpinen Gletschertourismusstandorten (n=1330) zu ihrer Besuchsmotivation und ihrer Klimawandelwahrnehmung und verwendeten eine latente Klassenanalyse zur BesucherInnensegmentierung. Eine zweite Befragung an der Pasterze/Franz-Josefs-Höhe (n=201) gibt Einblicke in die Positionierung von Gletschertourismusstandorten und die Rolle des Gletschers als Kern des touristischen Attraktionssystems. Die Ergebnisse zeigen, dass LCT-Motivationen für BesucherInnen aller Standorte wichtig sind, die Gletscher als gefährdete Objekte wahrnehmen. Das Beispiel der Pasterze zeigt, dass für die meisten BesucherInnen der Gletscher als solcher nicht primär ausschlaggebend für die Reiseentscheidung ist, sondern eher einen (kleiner werdenden) Teil des gesamten Landschaftserlebnisses darstellt. Eine LCT-Positionierung wäre daher als Strategie zu eng und zu kurzsichtig, während eine Transformation von Gletscher- zu Landschaftswandel-Destinationen eine tragfähige Positionierung mit langfristiger Perspektive zu sein scheint.

Phytoremediation stands as a crucial tool for addressing pollution, yet its application in Europe remains inadequately explored. Taking Serbia as a test case, this literature review delves into the state of knowledge regarding phytoremediation, exploring the regional distribution of contaminated sites, the prevalence of analysed contaminants, and the diversity of plant species employed for phytoremediation. Analysis revealed 24 distinct locations, 11 sampling parts, scrutiny of 24 potential toxic elements (PTEs) and nutrients, and the involvement of 65 plant species. Predominantly, research sites were associated with industrial areas, particularly mining sites. The efficacy of various plants varied across multiple factors, with soil, roots, and leaves emerging as the most frequently sampled components in reviewed manuscripts. Notably, the scientific literature emphasized Cu, Zn, Cd, and Pb as the most frequently studied PTEs in the context of phytoremediation. This review underscores the need for increased attention to phytoremediation research in Serbia, advocating a more widespread and intensive exploration, both geographically and in research efforts. The compilation of plant species employed for phytoremediation offers valuable insights into the effectiveness of particular species in distinct phytoremediation practices.

Published: May 2024

In addition to enabling students to acquire the knowledge and competencies necessary for their professions, higher education institutions should also support the formation of broad civic attitudes among students. University participatory budgets (PB) are an example of a tool for reaching this goal. The purpose of the presented research was to analyse the degree and scope of their use by public universities in Poland, with particular focus on the context in which PBs educate young citizens. The aim of the study was to fill the research gap regarding the lack of knowledge about the scale, importance and potential educational dimensions of PB implemented at public universities, by means of analysing the use of PBs at all 92 public universities. To this end, the budget regulations, orders, informational material and other documents available on the universities’ websites regarding participatory budgets were studied, which enabled the identification of 19 universities that implement processes meeting PB criteria, and 17 of including students in the process. Analysis of the data showed significant variation in terms of the scale, scope and stakeholders involved in BP processes, and although it should be noted that the educational goals are not directly indicated by universities, a number of activities were identified in the research that could ensure the achievement of differentiated educational outcomes at different stages of the PB process.

Published: May 2024

Intracerebral hemorrhage (ICH), the most common subtype of hemorrhagic stroke, leads to cognitive impairment and imposes significant psychological burdens on patients. Hippocampal neurogenesis has been shown to play an essential role in cognitive function. Our previous study has shown that tetrahydrofolate (THF) promotes the proliferation of neural stem cells (NSCs). However, the effect of THF on cognition after ICH and the underlying mechanisms remain unclear. Here, we demonstrated that administration of THF could restore cognition after ICH. Using Nestin-GFP mice, we further revealed that THF enhanced the proliferation of hippocampal NSCs and neurogenesis after ICH. Mechanistically, we found that THF could prevent ICH-induced elevated level of PTEN and decreased expressions of phosphorylated AKT and mTOR. Furthermore, conditional deletion of PTEN in NSCs of the hippocampus attenuated the inhibitory effect of ICH on the proliferation of NSCs and abnormal neurogenesis. Taken together, these results provide molecular insights into ICH-induced cognitive impairment and suggest translational clinical therapeutic strategy for hemorrhagic stroke.

Published: May 2024

Triangular cross-section color center photonics in silicon carbide is a leading candidate for scalable implementation of quantum hardware. Within this geometry, we model low-loss beam splitters for applications in key quantum optical operations such as entanglement and single-photon interferometry. We consider triangular cross-section single-mode waveguides for the design of a directional coupler. We optimize parameters for a 50:50 beam splitter. Finally, we test the experimental feasibility of the designs by fabricating triangular waveguides in an ion beam etching process and identify suitable designs for short-term implementation.
Assessing the bioaccumulation and translocation potential of vetiver grass for dioxins phytoremediation in Bien Hoa airbase, Viet Nam
Authors: Ngo Thi Thuy Huong , Nguyen Thi Thanh Thao
Published: May 2024

Dioxins (PCDD/Fs) are well-known toxic organic pollutants that accumulate in the environment and the food chain, imposing a risk to human health and the ecosystem. Due to the use of dioxin-contaminated herbicides during the US-Vietnam War, there are several hotspots in Vietnam with very high levels of dioxins. Phytoremediation has been increasingly developed in recent decades because of its low cost and environmental-friendly aspect. Vetiver grass is a plant that can remediate both organic and inorganic agents. In this study, the uptake and translocation of dioxins in Vetiver grass (Chrysopogon zizanioides) from the dioxin-contaminated soil was investigated in a field experiment on the Bien Hoa airbase, Vietnam. An experimental area was divided into six plots, of which three were planted with Vetiver grass and three served as control plots, with the initial dioxin concentrations as following: FC2>FC3>FC1>FT2>FT3>FT1.
Vetiver grass had grown well on the dioxin-contaminated soils, yielding high biomass and the level of dioxins in the roots of vetiver grass was positively correlated (r2 = 0.67; p<0.01) with its growth rate. During the first year of cultivation, Vetiver grass had the greatest capacity to efficiently accumulate dioxin. Accumulation occurs in the roots, with BAF>1 throughout the entire experiment period for FT3, and in the first year for FT1 and FT2. The dioxin translocation from the roots to the shoots was significantly lower than the BAF and less than one (TF<1), with the first and second sampling times having the highest values compared to the others. Dioxin concentrations do not provide a reliable indicator of its bioavailability but numerous other factors, such as physicochemical properties of the soil and microbes. Our study aims to contribute significant insights to capability of Vetiver grass to accumulate and translocate dioxins, hence the arsenal of dioxin remediation. Furthermore, we envisage translating our findings into practical applications in other areas, considering optimized planting techniques, growth conditions, and long-term sustainability.

Occupational health and safety management systems: a systemic approach
Authors: Ledic Neto Jerko , Moro Antônio Renato Pereira , Ensslin Sandra Rolim
Published: May 2024

Abstract Risks are intrinsic to any human activity. Occupational Health and Safety Management Systems (OHSMSs) are mechanisms designed to mitigate risks, protect workers, and ensure productivity. This study aimed to support researchers’ reflective analysis by examining scientific literature related to OHSMSs and identifying possibilities for future research with practical significance. Employing a qualitative approach, this systematic review was conducted using bibliographic procedures and action research. The intervention instrument ProKnow-C guided by a structured process from a constructivist perspective, was applied. A total of 3,130 studies were analyzed to select the bibliographic portfolio. The systemic analysis revealed that most articles neither demonstrate legitimacy nor consider companies’ particularities. The paper advances theoretical knowledge of OHSMSs by assessing relevant studies in the field, identifying evolution patterns, and highlighting gaps. A research agenda is proposed to guide the development of future models. We conclude that the challenges of designing ad hoc OHSMSs and incorporating the decision-makers’ knowledge throughout the process when addressed, have the potential to significantly contribute to the advancement of this field of knowledge.

Published: May 2024

Resumo Destacando-se como o principal produtor mundial de cana-de-açúcar e líder em volume de produção e exportação de açúcar, o Brasil desempenha papel central na fabricação de etanol e na geração de biomassa. Apesar da relevância do setor, poucos estudos se dedicaram a avaliar a eficiência técnica e os determinantes socioeconômicos da produção agrícola de cana-de-açúcar no Brasil. Diante da importância econômica da atividade e dessa lacuna na literatura, o objetivo deste estudo foi calcular a eficiência técnica da produção de cana-de-açúcar, utilizando o método de análise envoltória de dados (data envelopment analysis - DEA) para uma amostra de municípios nos estados de São Paulo, Goiás, Minas Gerais e Mato Grosso, por meio de dados do Censo Agropecuário de 2017 e da Agência Nacional do Petróleo, Gás Natural e Biocombustíveis. Adicionalmente, um modelo Tobit foi empregado para identificar as variáveis socioeconômicas que afetam a eficiência produtiva da cana-de-açúcar nesses estados. Os resultados apontaram que as mesorregiões de Ribeirão Preto e São José do Rio Preto, em São Paulo, e Triângulo Mineiro/Alto Paranaíba, em Minas Gerais, apresentaram as maiores eficiências de produção nos municípios. Além disso, os resultados do modelo Tobit indicaram que as variáveis socioeconômicas mais relevantes para os estados analisados foram a presença ou não de usinas no município e a mesorregião à qual o município pertence.

ABSTRACT Sex determination plays a crucial role in the post-mortem identification of human remains. One effective approach for obtaining sex-related data is to use measurements of anatomical structures such as the mandible. This study aimed to evaluate the potential of mandibular radiomorphometric indices from panoramic radiographs (PRs) for the identification of sexual dimorphism. The study sample included 300 PRs of individuals aged 51 to 80 years from the northeastern region of Brazil. Four linear measures and three numerical indices were analyzed with Inkscape® version 1.0.1 for Windows by two blinded evaluators. After statistical analysis, the results showed that the linear measurements obtained from PRs are a reliable method for sex identification. However, the calculated indices of these measurements exhibited lower efficacy for the same purpose. Therefore, PRs proved to be a valuable method for sexual identification through mandibular assessment.

Abstract The objective of this work was to determine the acidity levels to obtain adequate soil chemical attributes for the maximum fruit yield of blackberry trees grown in acidic soils subjected to increasing limestone rates. The BRS Tupy, Brazos, Guarani, and BRS Xavante blackberry cultivars were evaluated on the Typic Hapludox (LVdf) and Rhodic Hapludox (LVd) soils, to which four rates of dolomitic limestone were applied (0, 1.5, 3.0, and 6.0 Mg ha-1). The effect of liming on soil chemical attributes, in a 2×4 factorial arrangement (soils and limestone rates), as well as leaf nutrient content and fruit yield, in a 2×4×4 factorial arrangement (soils, limestone rates, and cultivars), were evaluated. The maximum fruit yield was obtained with 3.3 Mg ha-1 dolomitic limestone. The blackberry cultivars showed a high demand for Ca, Mg, and base saturation and a low tolerance to aluminum in the soils. From 3.3 Mg ha-1 dolomitic limestone, the maximum fruit yield of blackberry trees grown in acidic soils is obtained with pH 5.6, maximum tolerated aluminum saturation of 6%, Ca and Mg concentration of 45.3 mmolc kg-1, and base saturation of 48.3%.

Abstract The objective of this work was to evaluate the effect of the dietary addition of calcium anacardate as a source of phenolic compounds on the reproductive performance and blood antioxidant parameters of New Zealand White female rabbits. Twenty-seven New Zealand White female rabbits were distributed in a randomized complete block design with three treatments and nine replicates, considering one animal as the experimental unit. The treatments consisted of pelleted diets with different inclusion levels of calcium anacardate (0, 0.5, and 1.0%). The inclusion of calcium anacardate in the diets increased the concentration of phenolic compounds and the antioxidant capacity in the blood of lactating female rabbits. Calcium anacardate at the level of 1.0% improves the feed conversion ratio during gestation and increases the phenolic compounds and antioxidant capacity in the blood serum of female rabbits at 21 days of lactation.
The influence of the beam-column connection on the global results of multi-storey reinforced concrete structures
Authors: Manoel Lucas , Pachla Eduardo C. , Bolina Fabricio L.
Published: May 2024

Abstract The effect of the semi-rigid connection between beams and columns on the global behavior of reinforced concrete (RC) structures was investigated. The relative rotations in the nodes of the spatial frames were determined using the analytical approach proposed by Alva and El Debs. The rotational restraint factor ( α r) was defined and applied in each node of the spatial frames. RC spatial frames with total heights of 21, 42, and 63 m were considered. It was found that the semi-rigid connection increases the lateral displacements, the 2nd order effects, and the γ z values. The lower the stiffness of the nodes, the lower the influence of α r on the global results. The total fixed beam-column connections can lead to an unrealistic behavior of the spatial frame and thus to global results.
Simulating a reservoir on-site flood plan test: Operation Redbrook
Authors: Davis Merlin
Published: May 2024

The Canal and River Trust, undertaker for 71 high-risk reservoirs, has developed a schedule to conduct a desktop test annually and a full incident simulation exercise every five years. The paper covers the methodology for developing the desktop test, integrating international best practices and strategies from other industries. Practical insights for effectively conducting a desktop exercise, ranging from the selection of failure mode scenarios to debriefings, are provided. The importance of a full simulation was highlighted following the Toddbrook incident. The paper describes how to organise a simulation exercise and the considerations for selecting a suitable reservoir, based on access, location, stakeholders, failure mode and risk assessments on the backdrop of ‘Operation Redbrook’ conducted in June 2023. Pre-exercise arrangements include failure mode simulation, welfare, weather warnings, media responses and traffic management. The Trust also engaged the Local Resilience Forum, BT Emergency services and the contractor's supply chain. The challenges faced by contractors in deploying emergency pumps raise questions on proportionality of expenditure for crane pads, assessments for utilities, environmental impacts and traffic management. Strategies to disseminate lessons learnt and continuous improvement of the emergency response system within the Trust are covered.

Authors: Murat Yetis Sazi , Cakici Ziya
Published: May 2024

The Covid-19 pandemic has affected the entire world and changed many aspects of daily life, including transportation behaviour and preferences. This study examines the situation of transportation behaviour and preferences before and after the Covid-19 pandemic process through a survey study. A total of 471 people participated in the survey, and 30 questions were posed to participants regarding transportation modes preference, daily usage habits, public transportation usage rate, income status, perceived risk level of transportation systems, preferences before and after the pandemic process, and more. The answers were classified, evaluated and statistically analysed. The results showed that users were significantly affected by the Covid-19 process and changed their transportation mode preferences. The use of buses in urban journeys decreased, and the use of private vehicles significantly increased after the Covid-19 process. Hygiene was the key factor in travel, followed by the vehicle occupancy rate, ventilation, fare and travel time factors. The perceived risk levels of public transportation systems were ranked as metrobus, minibus (paratransit), bus, metro, tram and ferry. The study suggests that future transportation system designs should consider user preferences, as well as changes in education and working conditions, and pandemic conditions.

Reuso de efluente industrial: desafios e oportunidades no contexto brasileiro
Authors: Lima Fabiana Aparecida de , Achon Cali Laguna
Published: May 2024

Este artigo aborda o cenário atual do reuso e relaciona a sua aplicabilidade com a legislação pertinente. A pesquisa foi desenvolvida através de revisão bibliográfica sobre o reuso da água, voltada reuso principalmente para efluentes industriais, com o objetivo de expor os obstáculos que esta prática possui no cenário atual do país e também analisar as contribuições que advém para a expansão do reuso. A minimização da extração dos recursos, a promoção de uma gestão integrada do uso da água e o oferecimento de benefícios ambientais, sociais e econômicos para a sociedade foram os principais fatores que alavancaram o estudo do tema. Os resultados obtidos através da matriz de SWOT, indicam que o desenvolvimento de tecnologias de tratamento podem ser uma alternativa benéfica para os setores agrícola e industrial, mas no cenário atual a falta de legislação e normativas para embasamento do desenvolvimento e implantação de tecnologias de reuso ainda é um fator impactante para o crescimento das práticas. A conclusão do estudo propõe que para implantação das práticas de reuso é notório primordialmente a criação de leis para o direcionamento a processos e tecnologias de reuso, assim como a parâmetros principalmente no ramo industrial e também as práticas de conscientização da sociedade em paralelo ao desenvolvimento das leis e normas relacionadas ao reuso.

Published: May 2024

В работе представлены проблемы системы озелененных территорий, урболандшафтов (УЛ) г. Минска (на примере доминирующего вида Западной группы комплексов), заключающиеся в подверженности неблагоприятному воздействию химического и физического загрязнения, а также формировании крайне низких показателей обеспеченности населения озеленёнными пространствами. Для поиска путей решения этих проблем выявлены главные источники негативного воздействия на зелёные насаждения. Также проведено полевое обследование 226 деревьев на 7 площадках древостоя. Полученный набор дендрометрических показателей (изреженность кроны; цвет хвои; усыхание хвои; усыхание ветвей, механические повреждения; окорение ствола), позволил произвести расчет индекса жизненного состояния насаждений в рамках заложенных площадок. Результаты расчетов послужили основой для выявления категории жизненного состояния насаждений общего пользования Западной группы урболандшафтов Фрунзенского района и позволили дать рекомендации по оптимизации их системы озелененных территорий.

На примере охранной зоны Аргунского музея-заповедника, охватывающую средне- и высокогорную части Чеченской Республики, приведена ландшафтная структура рассматриваемой территории, которая включает в себя 6 типов ландшафтов, пространственное распространение которых имеет характер высотных поясов с континуальными границами, среди них - два вторично-производных типа, образованных в результате сведения условно коренных лесов. В соответствии с природным инвариантом при помощи контент-анализа историко-географических источников временного диапазона второй половины XIX - первой половины XX вв. рассмотрены категории землепользования в рамках специфичных административных границ, оконтуривающих границы горных чеченских обществ по естественным рубежам. Было установлено, что для всей территории музея-заповедника в указанный исторический период пастбищное животноводство было доминирующим типом хозяйственной деятельности ввиду обширных ареалов злаково-разнотравных субальпийских лугопастбищ. 30 горных обществ, исторические границы которых ныне охватывает охранная зона музея-заповедника, были поделены на 10 категорий в соответствии с обусловленными природным фактором типами землепользования и этнокультурными особенностями проживающих локальных сообществ.

Рассмотрена изменчивость атмосферных осадков по сезонам года, на основании которой делается предположение, что осадки не являются главной причиной особенностей водного режима и снижения максимального стока. В качестве доминирующего фактора современных изменений высоты половодий выступает состояние подстилающей поверхности, а именно, глубина промерзания и осеннее увлажнение почвы, которые на фоне повышения температуры воздуха регулируют снеготаяние, насыщение почвы водой и образование склонового и речного стока. Глубина промерзания почвы син-фазна величине максимального стока.

Представлен анализ ландшафтных предпочтений местных сообществ и формирования природно-хозяйственных систем (ПХС) Уймонской котловины и ее горного обрамления. Установлено, что ландшафтная обстановка в Уймонской котловине, благоприятная для земледелия, способствовала формированию в ее пределах, начиная с конца XVIII - начала XIX вв., ПХС современного типа. Основу пространственной структуры данной ПХС составляли пригодные для распашки геосистемы. Оформление структуры ПХС произошло уже к началу ХХ в. В дальнейшем эта структура лишь модифицировалась.

В работе на основании исторических данных рассмотрены изменения в распространении природно-антропогенных геосистем Среднего Приамурья в период с 1928 по 1941 гг. в связи с созданием нового региона - Еврейской автономной области. Определено, что первыми для заселения и сельскохозяйственного освоения использовались ландшафты, наиболее благоприятные по условиям увлажнения и транспортной доступности. Важным также был фактор изученности территории. В изучаемый период отмечалось расширение площади созданных в предыдущие периоды функциональных категорий природно-антропогенных ландшафтов (в первую очередь, сельскохозяйственных) и появление новых - промышленных, городских селитебных с увеличением степени трансформации геосистем. Пирогенный фактор преобразования ландшафтов имеет унаследованный характер. Сформировалась пространственная структура землепользования, отражающая сочетание природно-антропогенных геосистем разных типов и сохраняющаяся сегодня в виде приамурской и прижелезнодорожной зон.
