Energy prices and the structure of inflation in European Union countries
Authors: Markowski Łukasz , Kotliński Kamil
Published: September 2024

Since 2022, in almost every inflation category, a strong divergence in price dynamics among the EU countries has become visible. The first aim of this paper is to assess the impact of changes in energy prices on the differentiation in price dynamics in individual inflation categories in EU countries. The second aim is to isolate those components of inflation that have significantly differentiated the countries in the crisis year of 2022. The research was conducted based on the vector-autoregressive model, the Granger causality test, cluster analysis and analysis of variance. It can be concluded that there is a causal relationship between energy prices and the differentiation in the price growth rate in certain inflation categories. In 2022, the EU member states were divided into two quite distinct clusters. This article adds value to current research by taking into account the level of variation in the inflation structure among EU countries.

Authors: Gillani Farkhanda , Imran Muhammad Babar , Ahmad Warda , Zafar Saira , Rubab Nayyar , Khan Muhammad Ejaz , Afzal Muhammad Shahzad
Published: September 2024

Background: We report a case of a 54-year-old female patient with carcinoma of the left breast with persistent methylene diphosphonate (MDP) uptake in sclerotic osseous lesions. These lesions were finally declared treated osseous metastatic lesions due to non-avidity on the F18 FDG PET-CT scan, normalization of CA-15.3, and resolution of bone pains. To the best of our knowledge, this has not been reported previously. 
Case presentation:
A 54-year-old woman with persistent backache was referred for further evaluation by a Tc99m MDP bone scan. A Tc-99mmMDP bone scan showed wide-spread skeletal metastatic disease. Magnetic resonance imaging (MRI) showed extensive marrow disease involving the spine and iliac bones. A bone marrow biopsy revealed metastatic carcinoma with a tumor phenotype favoring breast primary. On further workup, the patient was diagnosed with invasive ductal carcinoma of the left breast and was treated with cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitors along with hormone therapy and bisphosphonates, followed by radiation therapy for bone metastasis. The skeletal metastatic disease remains static on three consecutive Tc99m MDP bone scans, despite the clinical improvement and decreased tumor marker levels.
The F18-FDG-FDG-CT scan done for monitoring treatment response revealed multiple non-avid sclerotic osseous lesions, favoring treatment response. The patient was continued with the same treatment, and a follow-up Tc99m MDP bone scan after 6 months revealed no interval change in the reported lesions compared to the initial scan. However, a synergistically performed F18 FDG PET-CT scan again showed multiple non-avid sclerotic osseous lesions suggestive of treated metastasis.
Conclusion: This case highlights the importance of 18F-FDG PET-CT in evaluating the treatment response, especially in patients with symptomatic improvement and falling tumor marker levels with static disease on repeated Tc99m MDP bone scans.

Published: September 2024

Background: Acute otitis media (AOM) is among the most common infections in children, particularly in developing countries where specific guidelines for treating conditions like AOM are often lacking.
Objective: This study aimed to assess the knowledge and practice of the general population in the Al-Baha region of Saudi Arabia regarding AOM and its treatment, and its association with other different sociodemographic variables (age, gender, and educational level).
Materials and Methods: This cross-sectional study was conducted on a sample of 409 participants in the Al-Baha region, Saudi Arabia, using a self-administered questionnaire distributed online. The obtained data were analyzed using Statistical Package for Social Sciences Version 25.
Results: A sample of 409 participants, predominantly female (67.7%) and aged between 18 and 30 years (61.1%), completed an Arabic-language questionnaire distributed via social media. The results revealed that while 31.5% of participants recognized bacteria as the primary cause of AOM, there was significant variability in understanding the condition's symptoms and treatment. Alarmingly, 41.1% of participants incorrectly believed that AOM always requires antibiotic treatment, highlighting a common misconception. Additionally, 37.7% acknowledged the potential for antibiotic resistance with frequent use. Notably, the internet was identified as the most important source of information by 65.3% of respondents. A significant association was found between the number of children and knowledge levels, with participants having 4-7 children showing the highest percentage of good knowledge.
Conclusion: The study concludes that despite some awareness, a substantial proportion of participants exhibited limited knowledge about AOM, particularly regarding its causes and potential for spontaneous resolution. These findings underscore the need for targeted educational initiatives to improve understanding of AOM and promote the appropriate use of antibiotics, emphasizing the condition's natural course and the risks associated with the overprescription of antibiotics and the rising threat of antimicrobial resistance.
A multifuncionalidade da agricultura presente em A Revolução Brasileira, de Caio Prado Júnior: reforma agrária e relação com a terra no Brasil
Authors: Leme Trivellato Gabriela Maria , De Lima Leme Luciana Maria , De Lucas Ademir
Published: September 2024

No clássico A Revolução Brasileira, Caio Prado Júnior critica os teóricos de sua época por elaborarem as bases de pensamento para a reforma agrária no Brasil a partir dos moldes europeus. A reforma agrária europeia fundada na posse pela terra parte da iniciativa de camponeses, indivíduos cujo reconhecimento social está condicionado à função produtiva e o pertencimento à terra e a uma determinada localidade. Diferentemente, o caso brasileiro parte de um sistema escravista, no qual as pessoas que exploram a terra apenas vendem a sua força de trabalho. Uma vez que a luta pela posse da terra estaria atrelada à relação que as pessoas estabelecem com ela, neste artigo, procuramos identificar elementos da crítica de Caio Prado Júnior que se associam ao conceito de multifuncionalidade da agricultura. Tendo em vista que esta linha de estudo reconhece papeis que vão além da função meramente produtiva da agricultura, especialmente aquela relativa à permanência das pessoas no campo e à manutenção do tecido social e cultural nas localidades.

Authors: Quadrado Alves José Caio , Moruzzi Marques Paulo Eduardo , Telles Marcondes Machado Queiroz Odaléia
Published: September 2024

O presente artigo discute as formas de legitimação das ações das famílias engajadas no acampamento Marielle Vive, localizado em Valinhos/SP. Considera-se em particular o papel do turismo comunitário como estratégia para maior visibilidade dos argumentos justificativos que fundamentam as reivindicações do Movimento dos Trabalhadores Rurais Sem Terra (MST) na região. Desta maneira, inverte-se a questão que comumente orienta as pesquisas em turismo. Ao invés de “o que justifica o turismo?”, a questão central do presente estudo é “o que o turismo permite justificar?”. Assim, serão explorados dois eventos de visitação e vivência no acampamento Marielle Vive que ocorreram por ocasião da 10ª Jornada Universitária pela Reforma Agrária (JURA), organizada notadamente por discentes da Escola Superior de Agricultura “Luiz de Queiroz” (ESALQ), e do 61º Congresso da Sociedade Brasileira de Economia Administração e Sociologia Rural (SOBER). Conclui-se que o MST de Valinhos/SP produziu nos últimos anos uma alternativa de turismo rural comunitário que apresenta grande potencial de estímulo ao engajamento de novos apoiadores, favorecendo a construção de alianças com outras organizações da sociedade civil organizada.

Authors: Rocha Bruna , Lima Pereira Elizabeth , Baccarin José Giacomo
Published: September 2024

Em 2009 foi aprovada a Lei 11.947, dando maior institucionalidade ao Programa Nacional de Alimentação Escolar. A nova legislação orientou os agentes executores a reforçarem o valor nutricional da alimentação escolar, priorizando os produtos in natura ou com mínimo grau de processamento. Tornou obrigatório, pelo Artigo 14 (A14), no mínimo 30% dos repasses para a alimentação escolar serem gastos com produtos da agricultura familiar (AF), priorizando os agricultores do município ou região. O objetivo foi verificar como as prefeituras da Região Metropolitana de São Paulo executaram, em 2018 e 2019, o A14 em nível de cumprimento e adequação da compra às condições dos AF. Foram analisadas chamadas públicas municipais e as prestações de conta da alimentação escolar dos municípios junto ao FNDE. Conclui-se que as chamadas públicas se adequaram aos AF, mas o cumprimento do A14 apresentou deficiências e inadequações.

Published: September 2024

O presente artigo é um recorte da tese "A construção da autonomia das mulheres rurais diante dos dilemas nos assentamentos” que deu continuidade às pesquisas realizadas pela autora e aos projetos do NUPEDOR. Trata-se de uma pesquisa qualitativa nos assentamentos da região de Araraquara-SP, que teve como objetivo principal analisar como se dá a construção da autonomia das mulheres, identificando qual o lugar que a reprodução social ocupa na vida e no trabalho delas nos assentamentos e nas unidades familiares de produção, tendo como obstáculos a estrutura patriarcal e as desigualdades nas relações de gênero. Diante do cenário de desvalorização do trabalho da mulher nas atividades agrícolas tradicionais, as atividades consideradas não agrícolas podem viabilizar uma liberdade financeira, mesmo que parcial, para as mulheres assentadas, especialmente quando participam de organizações femininas, o que pode ser considerado fator de apoio à expressão de autonomia da mulher.

Authors: Moni Rabha Anju , Bhuyan Geet
Published: September 2024

Background and Aims

Suicide among people experiencing homelessness is a rising concern, as due to the current economic and geopolitical reasons, people experiencing homelessness are on the rise. Studies have reported a higher rate of suicide among persons experiencing homelessness than the general population. The current available data and interventions to address this issue are limited. This research is aimed to review interventions available, specifically to address suicide and suicidal behavior among people experiencing homelessness.

Material and Methods

Electronic literature search was conducted using Google Scholar, PubMed, Science Direct, EMBASE, and Scopus up to July 31, 2024.

Result

A total search of 4035 studies was identified via literature, among which seven studies were included for the review.

Discussion

The factors causing higher suicide in the homeless population are multifaceted. The few studies available in this area show the efficacy of cognitive therapy for suicide prevention (CTSP), dialectial behavioral therapy (DBT), and electroconvulsive therapy (ECT) along with the efficacy of housing and emotional regulation in suicide prevention.

Conclusion

Limited data is available in this area. This marginalized group needs a holistic approach in suicide prevention, addressing both psychiatric as well as social aspects.
Parental non-compliance to childhood safety practices: A cross-sectional study
Authors: Kaur Ravleen , Kumaravel Sambandan , Mondal Nivedita
Published: September 2024

Background & objectives

To assess the pattern of non-compliance to childhood safety practices among parents of children between one and five yr of age and to determine the reasons behind the same.

Methods

A descriptive, cross-sectional study was conducted on 120 children between one and five yr of age through a questionnaire-based interview of the primary carer. Poor compliance was defined as compliance to <85 per cent of the recommended practices.

Results

Of the total 48 injuries, 32 were serious (66.6%). Falls and burns/scalds were the two common types of injuries. Nearly three-fourths (72.5%) of families showed overall poor compliance. Poorest compliance was observed towards four safety practices namely, helmet wearing, restricting number of pillion riders to two on a two-wheeler, seatbelt wearing in a car and avoiding food items with a high risk of choking in children <3 yr. Parental perception of ‘unnecessary’ and ‘lack of knowledge’ were the main reasons behind non-compliance.

Interpretation & conclusions

Low compliance among families occurred with respect to safety on motor vehicles and avoidance of choking hazards. Change of parental perception and improved awareness is necessary for the prevention of unintentional childhood injuries.

Published: September 2024

Background & objectives

Food and waterborne illnesses remain a neglected public health issue in India. Events with large gatherings frequently witness outbreaks of acute diarrheal diseases due to consumption of contaminated food or water or poor food handling practices. In the present study, an outbreak of acute diarrhoeal disease (ADD) occurring among the attendees of a birthday party in rural Dibrugarh district in the northeastern Indian State of Assam was investigated.

Methods

Sociodemographic information along with details of ADD outbreak that included information about source of foods, food handlers, illness details, etc., were collected using an outbreak investigation form for descriptive and analytical epidemiology. Rectal swabs from affected individuals and food handlers were collected along with bore-well water samples and tested in the laboratory by performing bacterial culture, biochemical analysis and polymerase chain reaction. Due to the delayed report on the outbreak, collecting leftover food for laboratory testing and analysis was impossible.

Results

A total of 25 cases of ADD had similar signs and symptoms. The mean incubation period for developing acute diarrhoea was 26.36±8.76 (± standard deviation) hours from food consumption. The overall attack rate was 60.04 per cent (25/41); 20 per cent (5/25) required hospitalization. Thirteen rectal swab samples were tested for pathogens and found positive for Shigella sonnei. Antibiotic susceptibility test of isolated S. sonnei showed resistance to nalidixic acid, ciprofloxacin and cefotaxime. Consumption of one of the food items - chicken curry was significantly associated with illness (Odds Ratio=14.8; 95% Confidence Interval: 2.75-85.11); P value<0.05 and Population Attributable Fraction (PAF) was 70.18 per cent. The water samples were found satisfactory for human consumption.

Interpretation & conclusions

The findings suggested that S. sonnei infection could be implicated in the investigated food-borne diarrhoeal disease outbreak and that there was a potential for human-poultry cross-infection. Additionally, the study revealed concerning levels of S. sonnei resistance to recommended antibiotics and drew attention to their public health relevance.
Comparative effects of dry needling and instrument-assisted soft-tissue mobilization on hamstring tightness in patients with posterior pelvic tilt: A pilot study
Authors: Manzoor Urooj , Ilyas Maida , Kemall Faryall , Ahmed Syed Mukhtar
Published: September 2024

Objectives:

The objective of this study was to compare the impacts of dry needling (DN) and instrument-assisted soft-tissue mobilization on hip flexion, active knee extension (AKE), and posterior pelvic tilt (PPT) in participants with hamstring tightness.

Methods:

A randomized clinical pilot study was conducted at the District Headquarter Hospital and tertiary hospitals in the District Nankana Sahib, Pakistan. The study’s sample size was 36, and participants were randomized equally into two treatment groups. Group A received DN, and Group B underwent treatment with instrument-assisted soft-tissue mobilization. Hamstring tightness was assessed using an inclinometer to measure the range of motion for AKE and bilateral straight leg raise (BSLR). PPT was measured using an inclinometer at baseline and after treatment of four weeks.

Results:

Both groups showed a significant disparity in the mean of pre-and post-treatment values (P < 0.05) of AKE, BSLR, and PPT. A statistically significant disparity was found between both groups on AKE, BSLR, and PPT (P < 0.05) post-treatment of 4 weeks.

Conclusion:

Both DN and instrument-assisted soft-tissue mobilization were found to be beneficial for enhancing hamstring flexibility by improving hip and knee joint mobility. On the other hand, instrument-assisted soft-tissue mobilization was superior in increasing active knee extension, BSLR, and reducing PPT.

Authors: Walinjkar Jaydeep Avinash , Patel Afroz Qasim , Natarajan Sundaram
Published: September 2024

We report a case of a 60-year-old lady presented to us with a sudden painless diminution of vision in the left eye (LE). Her best-corrected visual acuity (BCVA) was counting fingers close to face in the LE. She was diagnosed with submacular hemorrhage (SMH) secondary to polypoidal choroidal vasculopathy (PCV). We performed a standard 25-gauge pars plana vitrectomy with subretinal tissue plasminogen activator injection along with an intravitreal injection of brolucizumab and perfluoro propane (C3F8) gas injection. Six weeks after the procedure, her BCVA improved to counting fingers at three meters. After another two injections of brolucizumab at one-month intervals, the BCVA improved to 6/9, N6. We present the long-term follow-up of this eye for nearly 18 months with improved visual acuity, that is, 6/36, N24 at the final visit. This technique shows favorable results in the case of massive SMH due to PCV.

Authors: Ait Naceur Hassan , Igmoullan Brahim , Namous Mustapha , El Badaoui Kamal , Bammou Youssef
Published: September 2024

The primary aim of this study was to assess landslide susceptibility in the N'fis watershed by leveraging Geographic Information System (GIS) and remote sensing data. Three statistical models, namely frequency ratio (FR), information value (IV) and logistic regression (LR), were applied and compared. The process began with mapping an inventory of 156 landslides where 70% of the data served to train the models and the remaining 30% was used for validation. The second step involved thematic mapping of 14 causative factors. Subsequently, landslide susceptibility was evaluated using the three methods and the resulting maps were classified into five risk levels. The accuracy of the maps produced by each model was then assessed using the area under curve (AUC) method. The findings revealed that the LR model exhibited the highest accuracy (89.71%) followed closely by the FR model (85.31%) while the IV model demonstrated the least accuracy (72.58%).

Published: September 2024

The antioxidant action of Butterfly pea flower (Clitoria ternatea L.) is believed to be attributed to its flavonoids, alkaloids and polyphenols components. These chemicals function as antioxidants, effectively neutralising free radicals and providing protection against skin damage caused by UV radiation. The objective of this study was to ascertain the IC50 value of butterfly pea extract and thereafter to evaluate the degree of customer preference and convenience towards pharmaceutical items. This study utilised ultrasound-assisted extraction with a solvent technique employing 96% ethanol to generate extracts. These extracts were then compounded into several topical formulations including cream, gel and face spray. Initial assessments were conducted on all compositions, encompassing organoleptic, homogeneity, pH, viscosity, specific gravity, adhesion, spreadability, wetness and irritation. This study also incorporated acceptance and customer preference as factors. The antioxidant activity of BPF extract was determined using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) technique by estimating the IC50 value. The analysis revealed that the BPF extract had a yield of 38.75%. The IC50 values for the gel, cream and face mist preparations were 97.70, 49.14 and 73.89 ppm respectively. The cream recipe had the highest level of antioxidant activity. The determination of consumer preference has indicated that the majority of consumers favours face mist over other formulations.

Published: September 2024

Photocatalytic activity of Titania has a very intriguing mechanism with numerous potential uses such as air and water cleaning. The inclusion of silica improves its catalytic capabilities. The use of titania silica nanoparticles for photocatalytic activity in environmental applications is limited due to their activity in the UV region rather than the visible range. Titania silica nanoparticles were synthesised using the sol-gel method. Metal nanoparticles of vanadium, manganese and silver were synthesised and integrated into the titania silica using a green method. To clarify the structure property correlations for titania silica materials, several characterisation techniques such as SEM-EDAX, IR analysis, UV-Visible spectroscopy and XRD were applied. The photocatalytic activities of titania alone, titania silica and titania silica including the various metals were studied.

Published: September 2024

Soft corals are marine invertebrates known to be a prolific source of marine natural products. The genus Xenia is a rich source of bioactive compounds including terpenoids, steroids, saturated, unsaturated and poly unsaturated fatty acids. The water and methanol solvent extracts of soft coral Xenia macrospiculata Gohar, 1940 (X. macrospiculata) were screened for the novel chemical constituents using gas chromatography–mass spectroscopy (GC-MS). In the water extracts, seventeen compounds were identified including monounsaturated fatty acids (35.29%), saturated fatty acids (23.52%) followed by unsaturated fatty acids (5.88%), poly unsaturated fatty acid (5.88%), sesquiterpenoids (5.88%), aromatic compounds (5.88%), Alcohols (5.88%), thio compounds (5.88%) and pleuromutilin derivatives (5.88%). In methanol extract thirty compounds were identified, among which 30% are the poly unsaturated fatty acids (PUFA) followed by monounsaturated fatty acids (13.33%), unsaturated fatty acids (13.33%), saturated fatty acids (13.3%), sesquiterpenoids (10%), alcohols (6.66%), oxygenated heterocyclic compounds (3.33%), steroid (3.33%), organo-fluro compounds (3.33%) and aldehyde derivatives (3.33%). The GC-MS screening of water and methanol extracts of X. macrospiculata revealed the presence of several novel bioactive compounds. Fatty acids are potential nutraceutical compounds playing vital role in preventing the risk of cardiovascular disorders and fatty liver. In addition, these compounds also showed potential antioxidant activity, antimicrobial, antineoplastic, ichthyotoxic, cytotoxic, HIV-inhibitory, anti-inflammatory activity and 5α reductase inhibitory activity.
The Functional and Anti-bacterial Properties of Cellulose Acetate Propionate / Nano-Zinc Oxide Bio-Composites
Authors: Abdellah Ali Salah F.
Published: September 2024

In this research study, the investigations of how nano-zinc oxide (N-ZnO) could change the functional and antimicrobial features of cellulose acetate propionate (CAP) films, were established. As a result, three forms of CAP films comprising of 0.5%, 1.0% and 2.0% N-ZnO have been assembled. Following that, the physicochemical and barrier properties were assessed. Further, the anti-bacterial activities of prepared nanocomposite films towards Escherichia coli have been investigated using Fourier Transform Infrared (FT-IR). The obtained results demonstrated that 2.0% N-ZnO had the greatest impact on physicochemical and barrier properties. The FT-IR spectra revealed that all N-ZnO concentration interactions were physical, with no chemical reactions between the nanoparticles and CAP framework. The incorporation of N-ZnO improved the humidity level, water absorption and uptake capability of CA films which are essential factors in packaging manufacturing. The anti-bacterial effect of 2.0% N-ZnO formulation exhibited a stronger anti-bacterial impact compared to the remaining formulations. Subsequently, N-ZnO improved the overall properties of CAP films and the most satisfactory concentration for utilizing N-ZnO in CAP-based nanocomposite films was 2% N-ZnO.

The study conducts a comprehensive analysis of soil quality and heavy metal contamination in the vicinity of the Visakhapatnam Municipal Solid Waste Dumpsite, with a focus on the Gajuwaka municipality. The research addresses the escalating global concerns arising from improper waste disposal practices and their environmental repercussions. The Gajuwaka dumpsite, receiving diverse waste types, poses significant threats due to the leaching of heavy metals into the soil, impacting environmental components and human health. The study employs a robust experimental methodology involving soil sampling, metal extraction and Atomic absorption spectroscopy for elemental analysis. Waste characterization reveals the predominant presence of organic fractions and inert materials in the dumpsite. Seasonal physicochemical analysis of soil samples indicates variations in pH, moisture content, soil texture, organic matter and nutrient availability. Metal content generally decreases during the post-monsoon period. Phytotoxicity analysis of selected plant species demonstrates their capacity to accumulate heavy metals, particularly lead. The study emphasizes the urgent need for effective waste management practices, continuous soil monitoring and community engagement to mitigate environmental and health risks associated with waste dumping sites. The findings underscore the critical importance of sustainable waste management and environmental health. The study contributes valuable insights into the complex challenges posed by improper waste disposal practices and provides a foundation for the development of comprehensive strategies aimed at addressing environmental concerns.

В статье рассмотрены достоинства и особенности использования парной параллактической системы координат при локации объектов, включающих отображение парных параметров на осях координат в виде градиентов и их приращений и управление нормированием результатов построения. Это обеспечило условия достоверности измерений, управление их точностью и разрешающей способностью, независимость от влияния окружающей среды, при обеспечении их относительности и абсолютности. Обеспечение достоверности, управляемой разрешающей способности является основанием для использования параллактической системы координат, как теоретической основы теории измерительных антенн.

The article considers the advantages and features of using a paired parallactic coordinate system when locating objects, including displaying paired parameters on the coordinate axes in the form of gradients and their increments and controlling the normalization of construction results. This ensured the conditions of reliability, control of the accuracy and resolution of measurements, independence from environmental influences, while ensuring their relativity and absoluteness. Providing reliability, controlled resolution is the basis for using a parallactic coordinate system as the theoretical basis of the theory of measuring antennas.

METHODOLOGY OF QUANTITATIVE ASSESSMENT OF THE SIZES OF THE ZONE OF TECHNOGENIC DAMAGE OF BIOTA IN FORMATION OF STORAGES OF LARGE-DISPOSED SOLID WASTES OF MINING
Authors: Прошляков А.Н.
Published: September 2024

Проведено исследование, позволяющее оценить уровень воздействия отходов горного производства на естественную биоту, прилегающую к границе отвала. Предложен механизм образования динамического экотона и расчетная схема для определения его линейного размера. Показано, что динамический экотон, ширина которого определяется по величине диаметра наиболее крупной фракции, структурирован на элементарные участки, размер которых пропорционален среднему диаметру единичного куска размещенной здесь фракции. Для определения степени техногенного поражения биоты в пределах динамического экотона предложен показатель проективного покрытия биоты породой. Степень повышения экологической нагрузки при создании отвалов может быть оценена коэффициентом вторичного воздействия. Предложена методика расчета реальной площади техногенного поражения биоты при размещении породного отвала, а также коэффициента вторичного экологического воздействия.

A study was conducted to assess the level of impact of mining waste on natural biota adjacent to the border of the dump. A mechanism is proposed for the formation of a dynamic ecotone and a computational scheme for determining its linear size. It is shown that a dynamic ecotone, the width of which is determined by the diameter of the largest fraction, is structured into elementary sections whose size is proportional to the average diameter of a single piece of the fraction placed here. To determine the degree of technogenic damage to biota within the dynamic ecotone, an indicator of the projective cover of biota by the breed is proposed. The degree of increase in environmental load when creating dumps can be estimated by the secondary impact coefficient. A technique is proposed for calculating the real area of technogenic damage to biota when placing a waste dump, as well as the coefficient of secondary environmental impact.
