At the same time, the pharmaceutical industry ensures economic stability and security of the state. The main pharmaceutical products - medicines - are considered essential goods, which increases the profitability of this industry. Speaking about companies in the pharmaceutical sector, it should be noted that they bear a high degree of responsibility. This is due to the fact that the results of companies’ activities have a direct impact on human life and health. The relevance of the chosen topic lies in the fact that creating a business in the pharmaceutical industry is an attractive project from an investment point of view, through which an important social mission is realized. However, the implementation of financial and economic activities in this sector of the economy is associated with many restrictions, including mandatory registration of medicines, obtaining licenses, etc. Therefore, when entering the pharmaceutical market, a young business needs to take into account many specific factors that influence their activities. The purpose of this article is to study the features of the pharmaceutical industry and formulate an enterprise investment project in this area. To achieve this goal, the specifics of the pharmaceutical sector were identified, and the main regulatory measures in this area were determined. As a result of the study, an analysis of the main aspects of doing business in the pharmaceutical industry was carried out, a marketing analysis of the dietary supplement market was carried out, and an investment project for the enterprise was developed. The information base for the study was the scientific works of scientists on the research problem. analytical reports and reviews of the pharmaceutical market. In the process of research, such general scientific methods and techniques were used as analysis, generalization and systematization of the scientific information base, study of analytical and statistical collections, and graphic methods. Creating an effective investment project for an enterprise in the pharmaceutical industry is possible provided that the business clearly understands its responsibility, its compliance with legislative regulations, the use of advanced production technologies, high-quality raw materials, as well as when conducting high-quality clinical studies and ensuring quality control of products. In this case, special attention should be paid to the formation of the company’s brand and marketing strategy.
Differentiating Neuropathic and Inflammatory Heel Pain: Clinical Evaluation and Diagnostic Utility of the Sural Nerve Ankle Block
Authors: Tailor Dhaval M , P N Kulkarni
Published: December 2024

Background: Heel pain is a prevalent issue with diverse aetiologies, including neuropathic and inflammatory causes, each requiring different therapeutic approaches. This study aims to differentiate between these types of heel pain using clinical evaluation and the sural nerve ankle block as a diagnostic tool.
Methods: This prospective analytical study was conducted in the Department of Orthopaedics at Krishna Institute of Medical Sciences, Karad, India, over an 18-month period. A total of 50 patients aged 18 years and above presenting with heel pain were included. After obtaining informed consent, patients underwent clinical assessment, including palpation, Windlass test, Gore’s sign, and Visual Analogue Scale (VAS) scoring. A sural nerve block was administered to assess its diagnostic value, and VAS scores were recorded immediately and at various follow-up intervals.
Results: Neuropathic pain was characterized by burning sensations, persistence throughout the day, unilateral distribution, and positive Gore’s sign, whereas inflammatory pain showed sharp morning pain, bilateral distribution, and positive Windlass test. Immediately post-block, neuropathic pain patients showed significant pain reduction, which persisted over time, while inflammatory pain patients exhibited minimal improvement. The sural nerve block proved effective in diagnosing neuropathic pain.
Conclusion: Clinical assessment combined with the sural nerve block can effectively distinguish neuropathic from inflammatory heel pain. Neuropathic pain patients experienced significant relief post-block, confirming its utility as both a diagnostic and therapeutic tool in neuropathic cases.

This review provides an updated list, morphological characterization,
and an artificial dichotomous key for identifying Pimelodidae fish species
of Bolivia. 346 specimens deposited in the UMSS–Museo d’Orbigny
Ichthyological Collection (Cochabamba, Bolivia) were examined. The
morphological characterization was based on 41 measurements. The
species list considered the museum collection and records available in the
literature for Bolivia. Forty-eight species and 24 genera were identified
from the Amazon (44) and La Plata (16) basins. New records for Bolivia were
Hypophthalmus celiae, H. oremaculatus, Iheringichthys megalops, and
two new potential species were identified within the genus Propimelodus.
Additionally, two new undescribed genera are listed: one collected from
the bottom of the Beni River channel (three specimens), and the second
from the bottom of the Beni and the Mamoré river channels in the north
of Bolivia (one specimen). Species groups such as Pimelodus gr. blochii
and P. gr. maculatus are taxonomically challenging and difficult to identify
due to morphological similarities. This study reveals the high diversity of
Pimelodidae in Bolivia, and the presence of new genera and species.

Socio-Economic Factors Contributing to Human Trafficking in Pakistan
Authors: Sultana Munawwar
Published: December 2024

The nature and causes of human trafficking in Pakistan are multifaceted and are closely linked with the socio-economy context. Literacy, any form of the disease, ills, joblessness, and inequality makes people develop weakness and easily are forced to be traffickers or become victims of trafficking. These cover economic demand and poverty that force people to look for a way to survive, cultural inclinations that encourage gender discrimination and caste discrimination that exposes certain groups of society to human trafficking. These conditions make the environment favourable for traffickers to exploit people for labour or sexual purposes and continue the cycle of poverty and pain. This calls for multi-sectorial interventions alongside the legislation to fight human trafficking in Pakistan, where besides the causes that create the market for trafficking are the traffickers themselves. This paper aims to explore the socio-economic factors that prevail in human trafficking in Pakistan and put forward advisory steps for the appropriate response. Through the elimination of poverty, expansion of educational access, eradication of discriminative social and cultural, enhancement of law and order, and provision of numberless victim support services, Pakistan will be able to eradicate this heinous crime on human rights.

A coleta seletiva é uma ferramenta importante para a destinação ambientalmente correta dos resíduos recicláveis, pois gera impactos sociais, econômicos e ambientais, como a inclusão social de catadores e a geração de fonte de renda, reduz o uso dos recursos naturais como fonte de matéria-prima e diminui o montante de resíduos destinados para o aterro sanitário, contribuindo para o aumento da sua vida útil. O presente trabalho realizado no município de Sobral-CE, distante 240 km da capital cearense, objetiva diagnosticar os impactos socioambientais gerados pelo projeto piloto do modelo de coleta seletiva implementado. Trata-se dos Pontos de Entrega Voluntária - PEVs, local que poderá receber da população os seus recicláveis limpos e secos para serem destinados às associações de catadores. O projeto contemplou 5 (cinco) ilhas ecológicas distribuídas estrategicamente em prédios públicos em funcionamento, onde a intenção era formar naquele recinto equipes de monitoramento, fundamentais para a operacionalização do equipamento, como a sua manutenção, acionamento da coleta e coibir qualquer indício de pontos de lixo. Até julho de 2023 foram coletados e destinados para a Central Municipal de Reciclagem II, 2,5 toneladas de recicláveis, em sua maioria plástico, papel e vidro. O município já economizou R$ 244 mil reais, realizando a destinação final de mais de 4 mil toneladas de materiais recicláveis para as Central de Tratamento de Resíduos - CMRs, gerando fonte de renda para 87 famílias.

Published: December 2024

In the current higher education scenario, innovation plays a crucial role in fostering new alternatives for positioning complex institutions, such as universities, within competitive and dynamic environments. Recent studies highlight the need to broaden this discussion, with a  particular focus on the relationship between innovation and quality assurance processes. This article examines the development of convenience and technical competencies in higher education institutions, emphasizing the role of the Self-Assessment Commission (CPA). The CPA, responsible for governance in institutional evaluation, operates in alignment with ISO 56002 standards. Using a mixed-methods approach, the results indicate that the evaluation commissions responsible for quality assurance in Brazilian higher education have limited involvement in innovation processes, and universities tend not to support the development of these commissions' convenience and operational competencies. The conclusions suggest the need to increase the prominence and autonomy of these commissions, allowing them to actively participate in the innovation process within Brazilian higher education institutions.

O emprego do lodo de esgoto (LE) doméstico como fertilizante orgânico é uma opção para melhoria das propriedades físicas do solo. No entanto, a aplicação desse resíduo pode proporcionar efeitos positivos, insignificantes ou negativos nestes atributos, sendo necessária a investigação em diferentes condições experimentais. Assim, visou-se com esse trabalho avaliar o efeito do LE associado a fertilizantes minerais nos atributos físicos do Cambissolo Hálpico. O experimento foi conduzido em casa de vegetação utilizando-se seis tratamentos que envolveram a adubação a base de lodo de esgoto associado com cloreto de potássio e/ou calcário dolomítico e tratamento apenas com fertilizante mineral (NPK+C). Os atributos estudados foram: pH em água, matéria orgânica (MO) do solo, argila dispersa em água (ADA), argila dispersa (AD), grau de floculação (GF) e grau de dispersão (GD) de argilas, diâmetro médio ponderado (DMP) e diâmetro médio geométrico (DMG). O pH do solo foi menor nos tratamentos a base de lodo de esgoto, mesmo com a calagem. Enquanto o teor de MO foi menor no tratamento com NPK+C. O tratamento com adubação mineral apresentou os maiores valores de argila dispersa em água (ADA) e grau de dispersão de argilas (GD), consequentemente menor valor de grau de floculação (GF) em relação aos tratamentos adubados com lodo de esgoto e testemunha, que não diferiram entre si. Não houve diferença para estabilidade dos agregados via úmida e seca entre os tratamentos.

Os “brejos de altitude”, uma vegetação sub-montana que recobre parte do interior do Nordeste do Brasil. O município de Areia – PB, situado no Brejo da Paraíba, tem como uso e ocupação do solo fragmentos compostos na sua maior parte em vegetação nativa e atividades agropecuárias, para detecção de alterações que ocorrem no solo devido ao uso e manejo são comumente utilizados indicadores químicos e físicos. No entanto bioindicadores são mais sensíveis que indicadores químicos e físicos. É entendido que ação antrópica pode afetar diretamente o ambiente, dessa forma a atividade enzimática tem sida apresentada como ferramenta de avaliação da qualidade do solo. Entre as enzimas mais comuns encontradas no solo, estão a arilsulfatase e a β-glicosidase que desempenham papel importante na função metabólica do solo e são sensíveis aos fatores ambientais. Partindo desse pressuposto o presente trabalho objetivou avaliar a atividade enzimática, em ambiente de agricultura, ambiente de pecuária, ambiente de solo descoberto e vegetação nativa, com intenção de verificar a qualidade dos solos. Dessa forma foram selecionadas quatro áreas para as avaliações, correspondente a vegetação nativa, ambiente de agricultura, solo descoberto e ambiente de pecuária. Dessas áreas foram retiradas amostras de solo e enviadas para laboratório afim de obter os valores das atividades das enzimas arilsulfatase e β-glicosidase, matéria orgânica, ciclagem de nutrientes, armazenamento de nutrientes, suprimento de nutrientes e os índices de qualidade do solo (IQS) de fertibio, IQS biológico, IQS químico. Os resultados das análises de solos são atribuídos a plataforma web MIQS (Modulo Interpretação da Qualidade do Solo da tecnologia BioAS). Para análise dos dados o delineamento adotado foi inteiramente ao acaso com 4 tratamentos e 4 repetições. Os dados foram submetidos a análise de variância (ANOVA) a (p<0,05) e teste de Tukey para comparar as médias e análise de componentes principais (PCA) para cada variável analisada. O software utilizado para as análises estatísticas foi o R 4.3.0. Foi observado que a matéria orgânica no sol é fator determinante para atividade enzimática e para os índices de qualidade dos solos, os ambientes de pecuária e agricultura apresentaram valores mais elevados para esses, o ambiente de vegetação nativa tem indicado estabilidade e de acordo com a análise dos componentes principais os solos descobertos obtiveram respostas pouco representativa aos atributos índices de qualidade dos solos de maneira a se aproximar ao centroide.

Published: December 2024

A apicultura no Norte do Brasil possui grande potencial, todavia enfrenta desafios no fortalecimento das colônias em períodos de escassez de alimento. No ecótono Cerrado-Amazônia, a produção é promissora, mas ainda limitada ao mel. Neste sentido, o estudo visa avaliar a produção de geleia real por abelhas melíferas neste ambiente. O experimento foi realizado no apiário do Centro de Ciências Agrárias da Universidade Federal do Norte do Tocantins, em Araguaína - TO. Para a pesquisa, as colônias foram preparadas e adaptadas, com o apiário sendo ampliado e reorganizado desde 2021. O método utilizado foi o de Recria Orfanada, com três conjuntos de colmeias: uma produtora de geleia real e quatro colmeias suporte. As colmeias de suporte doaram abelhas e larvas para manter a produção constante. As larvas foram enxertadas manualmente em cúpulas e, após 48 horas, a geleia real foi coletada e analisada. O processo foi repetido três vezes por semana durante a safra apícola de 2022. O estudo no Tocantins sobre produção de geleia real exigiu ajustes, como reduzir o tempo das realeiras nas colônias de 72h para 48h e treinar a equipe. A produção variou de 0,54g a 2,17g por dia, influenciada pela rusticidade e desenvolvimento das colônias.

Comparative Soil Liquefaction Assessment Based on Multiple Investigations Methods
Authors: STANCIUCU MIHAELA , DIACONU ADRIAN , DOGARU IULIANA , MIRCEA IRINA
Published: December 2024

Submerged soils like loose sands or very soft clays are sometimes hard to evaluate for geotechnical purposes with classical methods like sampling and lab testing. In such soils, evaluation of liquefaction potential became very important, especially in large projects with hard geotechnical conditions where this issue is involved in almost all stages of design. The paper presents the results of the complex geotechnical evaluation of a site situated on the alluvial plain of the Danube, where geotechnical investigations, boreholes with Standard Penetration test measurements, laboratory analyses, and Cone Penetration Tests were completed with geophysical survey (cross-hole and down-hole). To obtain local representative correlations, we apply in the first instance several well-known formulas that link shear wave velocities (Vs) and Standard Penetration Resistance (NSPT). Still, the degree of fitness was very poor. In the second stage, we developed several evolutionary polynomial regression algorithms (EPR) which is a relatively new method used to find polynomial correlations between dependent and independent variables. This algorithm represents a method of solving optimization problems, especially when the objective function is nonlinear. The new predicted values were analyzed using some statistical parameters and using residual analysis, some values were excluded. Thus, based on proposed EPR models we obtain a new series of formulas for each layer which allows more precise correlations of geotechnical and geophysical parameters inside the sedimentary alluvial structure, by reference to the relations proposed in the literature. Based on these new parameters, an assessment of the range of variation of the safety factor against liquefaction based on multiple evaluation methods and the comparison between them was the main purpose of the presented paper.

Published: December 2024

Old downtown of city Požega was build in 18th century during the reign of Austro-Hungarian Empire. The center of the main complex is situated between the Palača velikog župana and Županijska palača on the east and medieval building on the west. The modern reconstruction includes an underground garage and two new buildings. Geotechnical investigation was conducted on the basis of conceptual architectural design, Rusanov ured do.o., Zagreb, 2022. Geotechnical investigation included exploratory drilling, CPTu testing, laboratory testing and geophysical surveys with masw and seimic refraction method. According to general geological data of the area, the complex was built on alluvial sediments with lateral alteration (changes) with loess deposits. Geotechnical investigation gave a more detail insight about the relationship of alluvial and loess strata and the location of the aquifer, which was also confirmed with geophysical survey and exploratory drilling. This relationship was defenied as an interval layers change of sand and gravel with clay materials.
Based on the results of field investigation and laboratory testing geotechnical soil model was created. On the basis of geotechnical soil model the foundation depth of the buildings and underground garage will be determined. It will also provide guidelines for choosing excavation technology of foundations and construction pits, along with shielding and support technology of construction pits and nearby buildings.
Experimental and numerical modeling of soil-vegetation-atmospheric interaction on slopes and erosion control using biopolymers and vegetation
Authors: Josifovski Josif , Susinov Bojan , N. Atanasovska Aleksandra
Published: December 2024

The impact of climate change on the infrastructure is alarming, thus creating several challenges that affect their lifespan and transport safety. The large temperature variations and more frequent intense rainfalls are seen as the main contributing factors for soil instabilities, landslides, and erosion. To understand the soil-vegetation-atmospheric interaction a holistic approach has been used that combines theoretical results and laboratory testing, as well as experimental and numerical modeling.
The hypothesis that intense rainfalls can have a significant impact on slope stability has been tested through various methods and models, but moreover, the use of a naturally-based solution for erosion resistance improvement, such as biopolymers in combination with vegetation has been examined. Nowadays, the usage of environmentally friendly materials for soil improvement has become very popular with the increased environmental awareness. Biopolymers are biodegradable substances, thus they don't harm the environment or people.
The paper presents an analysis of ideal slopes subjected to intense rainfalls, for which both physical and numerical modeling were performed. The results indicate that the impact of the atmosphere through intense rainfall can be significant on the surface layers on slopes where initially erosion occurs, later leading to local instability which eventually can end in global failure and even landslides. The experimental testing on the use of biopolymers as naturally based solutions has shown that the biopolymer improves not only the mechanical but also the hydrological soil parameters by forming a viscous gel matrix with a reinforcing bond between the soil grains that fills the pores. All test results confirm that the efficiency of the biopolymer as an additive significantly enhances the erosion resistance and stabilizes the soil, thus providing additional adhesion which in combination with the vegetation root system eliminates the erosion and improves the safety of slopes subjected to atmospheric actions.

Loading very dense crushed sand and gravels such as in this study is well known to induce volume contraction followed by dilation. In the saturated stated, water initially outflows from the specimen during drained shearing and subsequently inflows. Unexpectedly, the same material when unsaturated expels water continuously throughout both phases of volume change. A first group of samples proves unable to maintain their saturation even under a matric suction as low as 0.14 kPa. Capillary physics elucidates how this could originate from the observed presence of a millimetre size void network (up to 6 mm). Loading of these samples produced cracking of the high air-entry porous stone. This interfered in setting the matric suction by the axis-translation technique. Modifications to moulding preparation fixed this problem and eliminated the macroporosity. Consequently, specimens proved capable of remaining saturated up to an air entry-value of 4.7 kPa. Their subsequent loading in both saturated and unsaturated states confirmed drainage observations by others. Inspecting the soil-water characteristic curve while shearing shows clear trends: water retention increases during contraction then decreases while dilating. Hence contraction acts as wetting while dilation generates drying. Examining the degree of saturation throughout shearing in function of void ratio and matric suction reveals a soil-water characteristic surface. This permits to forecast how matric suction should evolve when loading in constant water content conditions. Further testing confirms this prediction. This indicates that the water-retention characteristic surface should allow modelling other drainage conditions such as in a constant volume test. This study also concludes that loading a granular material in a dense state enables to measure its drying soil-water retention surface. Consequently, shearing a loose material should permit exploring the wetting portion of the same surface. Implications on mechanical properties are additionally investigated.

The certainty of uncertainties is the hallmark of Himalayan Geology. Complex geological signatures attribute to occurrence of multiple generation folds, faults, thrusts, shear zones (bedding/cross shears), highly fractured rockmass, perpendicularly intercepting perennial nalas/gullies as lineaments at almost every 100-500m intervals etc. along with diverse climes; being the primary traits.
Although requisite investigations are done as per codal provisions/guidelines; encountering geological uncertainties can't be ruled out whatsoever. Moreso, complex geology with mixed ground conditions and associated brittle-ductile deformation poses difficulties not only in surface excavations, rather infringes greater challenge for tunnelling in DBM and/or TBM; leading to geological uncertainties. Such instances; if substantial in degree and difficult to handle/mitigate are tagged as Extraordinary Geological Occurrences (EGOs), which in turn lead to time and cost over-run of the project.
Exemplifying EGOs as encountered in 120 MW Rangit-IV Project, envisaging construction of 6.5km long (7.3m dia.) HRT and 958m long SFT (5.1m dia.) comprised of heavy underground seepage of 7000LPM, low-cohesive Coal band (8m thick), >2D Cavity, >1D Chimney and long-persistent shear zones (>0.5D). Also, experienced high squeezing >5% radial tunnel closure, occurrence of Gassy conditions with tunnel fire and explosion, high tunnel temperature (46°C) etc. in Lower Gondwanas which affected the work-efficiency and in turn the progress of tunnel. Nevertheless, such EGOs were tackled conventionally, yet with certain on-site innovations.
In Indian context, based on past experience of various tunneling projects, of recent EGOs are being quantified for sufficing contractual framework towards avoiding disputes between developer and executing agency. However, denotation of EGOs vis-a-vis degree/dimension/extent are project-specific; yet limited.
Hence, this paper is an attempt towards advocating a moderate yet universal numerical assignment for EGOs negotiating uncertainties in complex geological set-up and putting up arguments with reasoning for such advocation, thereby urging the need for framing an appropriate code/guidelines for EGOs.

The problem of soil properties heterogeneity in the massif and possible approaches of evaluating its regularities by means of three-dimensional numerical modelling of spatial fields of the studied parameters within the framework of geostatistical approach is considered.
It can be demonstrated that the structure of geological parameters fields (a) differs for different stratigraphic-genetic complexes of soils and rocks, (b) can be simpler than the combination of engineering-geological units, (c) the proposed approach is able to identify and explain significant deviations from the normal or lognormal distribution in its upper and lower quartiles, presenting practically in any geological subdivisions of the section. These outbursts in the maximum and minimum ranges are themselves an additional characteristic of soil heterogeneity; they testify to the non-randomness of such outbursts, their typicality, which should be taken into account, though usually rejected in standard statistical processing due to the smallness of data samples. Such analysis of heterogeneity allows to see the overall picture of the massif structure or part of it, and can be especially useful in case of mottled structure and frequent alternation of soil varieties, complicating detailed division of the soil profile. It can also provide additional important information like cracking distribution and potential for the development of unfavorable geological processes in them, like karst and suffusion.
Unlike a formal approach of subdividing the soil profile into a set of engineering geological units the proposed differentiation is based initially on composing the geological model consisting of bodies (strata, lenses, dykes, etc.) with varying origin, age and lithology and separated by distinct boundary surfaces. Additional internal boundaries in these 3D bodies are, on the contrary, diffusive and based on the analysis of spatial fields of the studied soil parameters (composition, density, moduli, etc.) by means of appropriate geostatistical procedures within a specialized software.
Landslide susceptibility models at a regional scale. The case study of the Region of Epirus in Greece

The current study presents the results of a landslide susceptibility model applied in the Region of Epirus, Greece. Initially, a detailed archive of 286 active landslides was created for the research area. Furthermore, four basic landslide predisposing factors were selected, geology, slope angle, elevation and land use, as they contribute to the landslide susceptibility assessment. The susceptibility assessment was based on the analysis of the relationships between the above factors and the occurrences of landslides applying the Frequency Ratio (FR) prediction model. FR is a statistical model of bivariate analysis that performs reliability tests on the results and is internationally accepted to quantitatively describe susceptibility. When FR>1 the class of the factor contributes strongly to the landslide event.
After completing the previous calculations, the final degree of landslide susceptibility was assigned through the Landslide Susceptibility Index (LSI). As the value of LSI increases so does susceptibility. In this way, five different susceptibility scenarios and relevant maps were performed for the study area, and all of them were evaluated for their ability to classify the landslides in the various susceptibility zones, in a satisfactory way.
By comparing the results, the most suitable model proved to be the one in which the slope angle is absent as it had the highest percentage of landslides coinciding with the three highest susceptibility classes. This led to the creation of a landslide susceptibility map for the entire Region of Epirus, that can be used for the assessment of landslide hazard and risk on a regional scale.
Slope instability and associated geohazards in Gisborne, New Zealand

Gisborne is a remote city on the northeast North Island of New Zealand, close to the Hikurangi Subduction Zone, subject to a range of geohazards. These primarily include tsunami, earthquakes, coastal erosion, flooding, mud volcanoes, and landslides. The city is remote from other urban centres, taking >3 hours to reach the nearest adjacent city via rural roads that are vulnerable to closure during and following natural hazard events. In particular, landslide risk in recent years has been exacerbated by urban and suburban expansion of residential development into erosion-prone steep hillslopes surrounding the city. The hills are underlain by weak Neogene sediments and uplifted Pleistocene estuarine deposits. Sentinel-1 InSAR has revealed the pattern of slope deformation across Gisborne’s steepland periphery from January 2016 to December 2021. Velocities in the line of sight were obtained from the stack of interferograms and projected along the direction of maximum slope, to extract the true displacement on the slopes. The ascending and descending data sets were combined to reveal the vertical and horizontal components of the deformation. Site investigations have revealed that the soils are smectite-rich and exhibit expansivity. In addition, small amounts of the toxic “asbestiform” mineral, erionite, have been detected in soil exposures in landslide scarplets. The erionite formed within altered volcanic ash, but the exposure risk is probably mitigated naturally by vegetation cover and rainfall. Slope deformation time series data was also compared with rainfall to identify seasonal changes, as well as shrink/swell of expansive soils. Despite clear evidence of the effects of tree removal, loading of slopes by construction activity, slope cutting, and installation of unconsented, inadequate retaining walls contributing to landslides, such activities continue to occur.
Large scale assessment of the liquefaction potential using the cone penetration testing (CPT): example of Sisak – Moslavina county in Croatia

On December 29th, 2020, an earthquake with a magnitude of 6.2 on the Richter scale struck the area of central Croatia. During and after the earthquake, several geotechnical phenomena appeared that directly impacted buildings and infrastructure. The most widespread phenomenon that caused significant damages is liquefaction, which occurred on almost 1600 ha of the Sisak – Moslavina County’s territory. As a phenomenon occurring during the strong seismic events in saturated non-coherent materials, it is characterized by turning the soil into a thick liquid, losing its strength and stiffness. As a part of large-scale investigations of the area in the post-seismic period, a Cone Penetration Testing (CPT) campaign was implemented to assess the probability of liquefaction occurrence. Considering the very large and statistically relevant number of collected data, the development of a map of a specific region followed, by interpolating the obtained results. As such, this map can be directly compared to the previous liquefaction assessment efforts which relied only on the limited indicators, such as overall geology and distance from the adjacent rivers.
