Authors: Ferreira Luiz Cláudio Costa , Almeida Alexandre Nascimento de , Santos Carolina Cassia Batista , Kipnis Bernardo
Published: October 2023

O Programa Nacional de Assistência Estudantil (PNAES) completa 12 anos de existência em 2020, contou com um orçamento em torno de R$ 1 bilhão em 2019, no entanto, há poucas iniciativas de avaliação dos seus impactos. O objetivo deste estudo é avaliar o efeito dos programas de assistência estudantil da Universidade de Brasília (UnB) no período de 2010-2014, por meio da comparação das taxas de evasão e retenção entre os estudantes participantes e não participantes da assistência estudantil. Os resultados indicaram que não houve diferença na taxa de evasão entre os dois grupos analisados. Quando avaliado em desagregado por cursos, a taxa de evasão variou inversamente proporcional ao prestígio do curso. A retenção dos estudantes da assistência estudantil apresentou ser maior comparativamente a dos estudantes não participantes nos cursos de médio e baixo prestígio. Os programas de assistência estudantil têm atingido o objetivo do PNAES, reduzindo a taxa de evasão e mantendo a média de retenção dos estudantes atendidos dentro dos parâmetros definidos pelo Ministério da Educação do Brasil (MEC). Destaca-se que, no caso da retenção, são necessários ajustes para que essa seja igual entre todos os estudantes da UnB, principalmente nos cursos considerados de médio e baixo prestígio.
Groundwater Quality Analysis for Wardha, Maharashtra, India
Authors:   Lovely Professional University, Shende Ashay
Published: October 2023

Arid and semi-arid regions significantly depend upon groundwater to meet their water demand, especially when groundwater is the only and limited resource for drinking and other human needs. The primary concerns are the excessive consumption of groundwater for agricultural and industrial activities, low recharge rate and percolation of impurities in groundwater, affecting groundwater quality and quantity. This study was performed to identify the variation in the water quality of groundwater of arid or semi-arid regions using geographical information system (GIS) and water-quality index (WQI). The database generated by analyzing samples of 3 decades (1990 to 2019) spatially varied over 68 sampling locations and the dataset was classified based on designated use. The dispersal of chemical constituents in groundwater over the study area was determined using GIS and water quality was classified based on WQI. The maximum concentrations of magnesium, nitrates and sulphates were found to be 307.6 mg/L, 600.16 mg/L and 890.0 mg/L, respectively, but the overall water quality was found varying between marginal and good due to tremendous variations. The southeastern and southwestern parts of the study area were found to be majorly affected with high concentrations of electrical conductivity, total hardness, chlorides and sulphates. Integrating GIS and WQI gives new knowledge on the spatial variation in groundwater characteristics for designated use. The integrated model derives valuable information for land-use planners and decision-makers on groundwater-resource management.

Authors:   The National Institute of Engineering, M. Hulagabali Anand
Published: October 2023

Reinforced earth retaining walls are being utilized more frequently in civil infrastructure projects as an alternate design structure to typical reinforced concrete walls and other structures for supporting backfill. The objective of the present study is to model and analyze a 2-dimensional Segmental Precast Concrete Panel (SPCP) wall using the 2-dimensional finite-element tool PLAXIS and analyze the behaviour of the wall concerning the effect of reinforcement type and surcharge loads. The present work also includes the investigations of the effects of reinforcement type and surcharge loads, as well as the influence of different supporting systems on the deformations and ground-surface settlements of the SPCP wall. Ribbed steel reinforcements, Polyethylene Terephthalate (PET) geogrids and Density Polyethylene (HDPE) geogrids are used to evaluate the wall deformations for reinforcement types. For ribbed-steel reinforcement, ground settlements and wall deformations are 14% and 25% less compared to those of PET and HDPE geogrid reinforcements, respectively. With the increase in surcharge on the backfill soil, wall deformations and surface-ground settlements are increased significantly by 150%. To decrease the deformations of walls resting on soft soil, pile foundations and aggregate piers are considered as supporting solutions. In the case of reinforced blocks with pile foundation as supporting systems, the wall deformations and settlement are 60% lesser than for aggregate pier supporting systems.

Three-dimensional Finite-element Analysis of the Influence of Tunneling on Pile Foundations
Authors: Abd El Raouf Moamen
Published: October 2023

Advancing tunnel boring machine (TBM) during tunnel construction induces a surface settlement, affecting adjacent buildings and facilities. A three-dimensional finite-element model (Plaxis 3D) was used to simulate and analyze this process. A comparison between the numerical model and field measurements of the Greater Cairo Metro (Line 3) was made to validate the obtained results. A sensitivity analysis was conducted to determine how changes in some parameters, such as constitutive models, pile position relative to the tunnel axis and pile spacing, affect the results of the finite-element model. Three constitutive models: hardening soil small (HSS), hardening soil (HS) and the Mohr-Coulomb (MC) models, were used to evaluate the effect of the constitutive models on the results. From the numerical analysis, it is clear that the numerical results are in good agreement with field measurements. The results of the HSS model are more realistic and closer to field measurements than those of the HS and MC models. Furthermore, the effect of the tunnel construction on the settlement of adjacent piles is virtually null at a distance of 2 D (where D is the tunnel diameter). Finally, increasing the pile spacing decreases the effect of tunnel excavation on adjacent pile foundations. KEYWORDS: Tunneling, Numerical models, Constitutive models, Pile foundation, Pile spacing
Numerical Analysis of a 3D Unit Cell Model for Soft Soil Reinforced with Different Granular Columns
Authors:   Djelfa University, Amin Yousfi
Published: October 2023

Recycled aggregates have been increasingly considered in recent years, owing to the limited supply of natural aggregates coupled with the corresponding carbon footprint. Recycled aggregates are aggregates prepared from construction and demolition waste. Their use aims to reduce energy consumption and contributes to reducing waste harmful to the environment. This study is based on a number of numerical tests using the finite element method of PLAXIS 3D software with the elastic-perfectly plastic behavior model and the Mohr flow criterion for all materials. A unit cell model of soft soil treated with three types of granular columns was loaded to failure: ordinary stone columns (OSCs), sand-fiber mix (SFM) and recycled aggregate porous concrete pile (RAPP). An extensive parametric study was conducted to investigate the effect of column type, friction angle, elasticity modulus, column length and geotextile effective stiffness on the behavior of soft soils. The results of numerical tests indicated that the bearing capacity of the recycled aggregate columns is three times greater than that of columns of natural aggregates. The findings of this research are given in the form of load-settlement graphs, which made it possible to release recommendations to carry out works using this technique.

Behavior of Natural Pozzolana-Lime-stabilized Clayey Soils Artificially Contaminated by Sulfates
Authors:   Faculty of Nature and Life Sciences and Earth Sciences, Gadouri Hamid
Published: October 2023

The use of lime in sulfate-bearing clayey soils has historically caused structural damage to infrastructures due to the formation of an expansive ettringite mineral. In this paper, a research was conducted to study the effectiveness of natural pozzolana (NP) for providing better stabilization of sulfate-bearing soils. Compaction and free-swell potential tests were first performed on lime-stabilized grey and red clayey soils (GS and RS) containing different contents of added sodium and calcium sulfates (2, 4 and 6% Na2SO4 or CaSO4·2H2O). Then, the same tests were repeated by adding 20%NP. The test results indicated that the presence of 4% and 6% Na2SO4 in the soil resulted in an abnormal increase in the swell potential of both lime-stabilized GS and RS. The X-ray diffraction (XRD) results confirmed the growth of the ettringite mineral responsible for this higher swell potential. However, the use of 8% lime with 20%NP in stabilizing sulfate-bearing clayey soils produced significant improvements in the optimum moisture content (OMC) and maximum dry density (MDD), as well as in the swell potential. The addition of 20%NP into the lime-stabilized GS and RS eliminated the harmful effect of Na2SO4. In addition, for 120-day curing period, the use of 6% CaSO4·2H2O was found very effective by reducing the swell potential of NP-lime-stabilized GS and RS from 7.33% to 0.4% and from 2.79% to 0.2%, respectively trips.

Authors:   Dayananda Sagar College of Engineering, Kumar G. Shiva
Published: October 2023

This article investigates the impact of Crumb Rubber Modified Bitumen (CRMB) and fibre additives (aramid fibre and basalt fibre) on the performance properties of Stone Matrix Asphalt (SMA) mixtures. Tests were conducted to evaluate mix design, draindown, cantabro loss, moisture sensitivity, rutting resistance and fatigue behavior. The Marshall method, the draindown parameters (ASTM D6390-11) and the cantabro loss characteristics (ASTM D 7064) were used to examine the mix design qualities. The modified Lottman test was used to assess the moisture sensitivity of SMA mixes. The roller compactor cum rut analyzer was used to assess rutting resistance. Findings showed that CRMB and fibre additives effectively controlled binder draindown and minimized abrasion loss in SMA mixtures. SMA-CRMB mixtures had higher draindown, but comparable cantabro loss than SMA-AF and SMA-BF mixtures. Incorporating CRMB and fibre additives enhanced moisture sensitivity, rutting resistance and fatigue behavior. SMA mixtures with 0.3% fibre addition displayed similar performance properties to SMA with CRMB. Further, substituting fibre additions for CRMB in SMA combinations may yield similar performance.

Seismic Behavior of an Inter-story Hinged Lateral Resistance Braced Frame
Authors: Ren Yu
Published: October 2023

Based on the deflection behavior of structural components occurring at the lateral deformation of moment frames, a new lateral force-resisting system, the R-BRACE Frame (RBF) system, was proposed. This system is capable of effectively limiting the inter-story drift response of tall buildings. An evaluation was conducted using the finite element method program SAP2000 to simulate the internal force distribution and deformation of the system. The equivalent lateral force procedure (ELFP), the capacity spectrum method (CSM), a linear time-history analysis and the pushover method were applied to assess the yielding mechanism of the structure under different earthquake intensity levels. The findings revealed that the sub-unit, referred to as an R-BRACE, had a major impact on improving a structure's lateral stiffness. The placement of R-BRACE units could guarantee controllable stiffness degradation and enhanced seismic ductility, but would not alter the vertical load transfer path of the initial structure, which makes the RBF system an ideal option for seismic retrofitting.

Computation of Flow Coefficient via Non-deterministic Approach of Fuzzy Logic Called "SMRGT" Based on Meteorological Properties
Authors:   Civil Engineering Department, Gunal Ayse Yeter
Published: October 2023

In light of the current global climate changes, floods have emerged as a significant hydraulic and hydrological challenge on a global scale. The primary contributors to the expansion of impermeable areas and the intensification of flood flow are extensive urbanization, the proliferation of concrete edifices and the construction of asphalt thoroughfares. Anticipating the flow beforehand will be conducive to the successful execution of the task at hand. The objective is to reduce the likelihood of harm to individuals and damage to assets. By accurately determining the flow coefficient, which is a significant factor in flood flow, it is possible to mitigate existing issues to a significant degree. Numerous methodologies for modeling flow coefficients can be found in the extant literature. However, most of these methodologies rely on black-box techniques and are not easily generalizable. Hence, the present investigation has opted for a novel methodology; namely, the fuzzy SMRGT method that takes into account the physical characteristics of the phenomenon and is designed to assist individuals who encounter difficulties in selecting the appropriate quantity, structure and rationale of membership functions and fuzzy rules within a given fuzzy set. The data comprising annual precipitation, temperature and relative humidity measurements was acquired from the Regional Directorate of Meteorology. The model outcomes were juxtaposed with the actual observations. Statistical parameters, such as the coefficient of determination (R2 ), the root mean square error (RMSE), the Nash-Sutcliffe efficiency coefficient (NSE) and the mean absolute percentage error (MAPE), were used to evaluate the performance of the model. The statistical test results were: (RMSE: 0.096, NSE: 0.90, MAPE: 17.3, R2 :0.96). The findings suggest that the SMRGT model is highly effective in accurately forecasting the flow coefficient and represents a robust approach for constructing membership functions and fuzzy rules.

Optimal Shear Strengthening of Severely Deficient RC Beam Using JFRP Laminate with Anchor
Authors:   University of Asia Pacific, Alam Md Ashraful
Published: October 2023

High-strength jute fibre-reinforced polymer (JFRP) laminates have recently been introduced to strengthen RC beams against shear. In contrast to synthetic-based composites, JFRP laminates would be more ductile, compatible with steel shear rebar and effective in reducing debonding due to their lower modulus of elasticity. The prime objective of this research was providing an optimal solution to strengthen a severely deficient RC beam against shear using an externally bonded JFRP laminate with anchor. Fabrication of the JFRP laminate was carried out with the maximum fibre content of 37.5% to obtain high tensile strength. Five full-scale RC beam specimens were cast. Shear strengthening was done by an externally bonded JFRP laminate with double connector, multiple connector and embedded-bar anchor systems. The dimensions of JFRP laminate were obtained based on proposed guidelines. Based on the experimental test, the average tensile strength of the fabricated JFRP laminate was found to be 162 MPa. Results also showed that the JFRP laminate with multiconnector anchor increased the maximum shear capacity of deficient RC beams by 89% and the beams had failed by the fracture of laminate. Beams strengthened with embedded-bar anchor had shown flexural ductile failure. Both beams failed after yielding of flexural bar. The proposed guidelines could be used for shear strengthening of severely deficient beams to enhance the maximum shear capacity using full strength of JFRP laminate with anchor.

Published: October 2023

Accurately identifying the vehicle load on the bridge plays a vital role in structural-stress analysis and safety evaluation. Also, extracting the spatiotemporal information of the vehicle’s is crucial for identifying the vehicle load. This study aimed to propose a vehicle spatiotemporal information-identification method based on machine-vision technology. First, digital video surveillance cameras were installed in the front and on the side of the monitoring section to capture real-time videos of vehicles passing through the monitoring section. The background-difference method was used to detect vehicles based on the frontal video. Subsequently, the transverse position was evaluated according to the distance between the vehicle’s license plate and the lane line. Other vehicle parameters, including the vehicle’s speed, the number of axles and the wheelbase, were identified based on the lateral video and the auxiliary lines with a known distance. Second, a laboratory model experiment and multiple field tests under different scenes were carried out to validate the efficiency and accuracy of the proposed method. The results indicated that the average identification errors of wheelbase for the model experiment and the field tests were all 1.12% and those of the vehicle’s speed were 1.25% and 1.35, respectively. Also, the average deviations of the lateral position were 2.57 mm and 2.69 cm, respectively. The variances of the identified error of the three parameters for the field tests were 0.78%, 1.83 cm and 0.54%, respectively. This verified that the proposed method has high accuracy, reliability and good anti-noise performance.

Published: October 2023

Today’s workforce not only requires specific content-area knowledge and skills achieved through formal education but also, and most critically, superior performance competencies including distinguishable behaviors. While formal education prioritizes easily detectable and measurable content-specific knowledge and skills, superior performance competencies such as cognitive, affective, and motivational skills remain secondary unless students engage in extracurricular activities in real-world settings. This qualitative study investigated the phenomenon of achieving an array of superior performance competencies through learning by doing, at one of the 2023 Destination Imagination events. This study marked the first fieldwork in which the principal researcher directly observed the event in its natural setting. Data were collected, analyzed, and interpreted concurrently during the event by means of observations, ordinary conversations, and an informal interview. The inductive data analysis included analytic memos, and midway hypothesis coding which confirmed the significance of immersing in such activities and resulted in two major findings: 1) participating in such meaningful real-world activities cultivates distinctive behaviors that drive exceptional performance, positioning participants to stand out among their peers; and 2) this involvement also equips students with the capabilities to excel upon entering the workforce, ensuring superior employee performance in their roles.
Exosomal prognostic biomarkers predict metastatic progression and survival in breast cancer patients
Authors: Ceran Serdar Ceyhan , Osmanlıoğlu Şeyma
Published: October 2023

Objectives

This study aims to comprehensively evaluate extracellular vesicle (EV)-based biomarkers circulating in body fluids with significant prognostic value in breast cancer (BrCa).

Methods

We systematically searched WOS, PubMed, and Scopus databases on 14 February 2023 for studies indicating overall survival(OS), progression/disease/event-free survival(PFS/DFS/EFS), and metastatic progression. We computed univariate(UHR) or multivariate adjusted(AHR) hazard ratios, and AUC values for all prognostic EV-based biomarkers of blood-origin using random effect model and Stata 16.0 software. Subgroup analysis was conducted for positive and negative prognostic factors.

Results

Twenty-one articles comprising twenty-six studies and 3,423 patients satisfied the inclusion criteria. EV-based negative biomarkers indicated low OS(UHR=2.31, CI=1.77–3.03, I2=60.12 %, p<0.001); worse DFS/PFS/EFS(UHR=3.91, CI=2.82–5.43, I2=19.08 %, p=0.24); increased risk for metastasis(pooled AUC=0.91). Out of 56 EV-based biomarkers that have been previously described, we identified PD-L2, sHLA-G, exo-XIST, and miR4800 as the best predictors of OS of BrCa patients. Expression levels of miR155, Annexin-A2, sHLA-G, PD-L2, miR1246, PSMA and the biomarkers constructing the EVP-panel hold significant potential to be combined in a prognostic-panel predicting DFS/PFS/EFS of BrCa patients. PD-L2 and sHLA-G standing out as leading biomarkers in both OS and DFS highlights the importance of immune system evasion for patient survival. In addition, we suggest that reinforcement with additional RNA biomarkers could significantly increase the metastatic prediction power of the previously described EVDX-panel.

Conclusions

This meta-analysis provides an overview of the liquid biopsy-based EV-biomarkers associated with OS, DFS, and metastatic progression of BrCa for the first time. Prognostic efficiency of the proposed panels should be further investigated before transition to clinical use.

Published: October 2023

This study aimed to investigate the effect of gold mining on soil properties. Soil samples were taken from the post-gold mining land, the property of PT Panca Logam Nusantara and PT Alam Buana Indonesia, and a nearby natural forest in Bombana, Southeast Sulawesi Province. The next step focused on specifying soil pH, total nitrogen (TN) and carbon (TC) concentration, C/N ratio, available phosphorus (P) concentration, cation exchange capacity (CEC), and exchangeable K, Na, Mg, Ca, Fe, Mn, Cd and Pb concentration, texture and spore amount, AMF resource and AMF colonization. The result shows that the pH in post-gold mining soil was higher than that in natural forest soil. Meanwhile, TN, TC, available P, and CEC of post-gold mining soil got lower compared with these of natural forest soil. The texture in the post-mining soil was clay loam, while that in natural forest soil was clay. Total of 10 AMF species belonging to five genera and three families were found in a post-gold mining area. Soil pH, CEC, soil texture, Mn, and total Fe had a negative relation with AMF colonization and spore count, while organic C, total N, C/N ratio, P2O5 and silt had a positive relation. Sand was proven to have a strong and positive correlation with the amount of AMF species. Adding organic matter and fertilization as well as applying mycorrhizal biofertilizers, were urgently required to support the effort in restoring post-gold mining soil.

Published: October 2023

Maize has attracted the attention of local governments due to its high yield potential and economic prospects, but the strategic value of this commodity has not been specific to particular locations. Therefore, this study aimed to assess degraded land suitability and determine the regional comparative advantages for maize development in the Gorontalo sustainable agriculture areas. The suitability class was assessed using Automatic Land Evaluation System software, while comparative advantages were determined using input-output and regional analysis. The input-output analysis was based on maize farming data from interviews with 80 farmers. This study also employed location quotient, specialization index, and localization index analyses based on maize, rice, and soybean production data for 2014, 2016, and 2018. The results showed that land degradation caused by soil erosion was dominated by moderate, heavy, and very heavy categories. Most of the actual land suitability for maize was classified as marginal suitable (S3) but became very suitable (S1) and moderately suitable (S2) after the limiting factors were improved. Furthermore, maize was profitable for the land suitability classes of S1, S2, and S3, and the commodity was most concentrated in Mootilango District. Based on the results, land management recommendations followed a pattern of recommendation I > II > III > not recommended.

Published: October 2023

This study aimed to screen some potential local seed grains for hydroseeding and describe their characteristics based on the literature review and a year of hydroseeding application. This study used six species/variants of Poaceae (Coix lacryma-jobi, Eleusine indica, Setaria italica (brown, black, and red), Sorghum timorense, S. bicolor, Themeda arundinaceae), five species of Leguminosae (Adenanthera pavonina, Cajanus cajan, Sesbania grandiflora, S. sesban, Indigofera sp.), a species of Cyperaceae (Cyperus javanicus), Sapindaceae (Sapindus rarak), Rhamnaceae (Ziziphus jujuba), and Moringaceae (Moringa oleifera). A seed germination test was held using soil media placed in 5 pots per species until 15 days after sowing (DAS). Characters were scored, and data were statistically analyzed. A field record of one-year hydroseeding applied on 6 m x 6 m post-coal mining land plot was presented. Some data such as pH H2O, pH KCl, conductivity, and soil organic carbon among hydroseeding areas, unrevegetated areas, and reference sites were observed. Results showed that there were 13 of 17 species could variably germinate. The fastest germination time was recorded for S. timorense, S. bicolor, red S. italica, C. cajan, and S. grandiflora, while the highest germination rate (≥50%) was black S. italica (80%), brown S. italica (58%) and S. bicolor (50%). The annual black and brown S. italica, S. bicolor, and S. timorense were highly recommended to be used in hydroseeding. The perennial C. cajan, Indigofera sp., S. sesban, and T. arundinaceae were also potential to be added into a hydroseeding slurry to improve pioneer vegetation multilayering structure and diversity.
Sorting the facts from the lots: Contribution of artisanal and small-scale mining (galamsey) to rural livelihood configurations in sub-Saharan Africa
Authors: Baddianaah Issah , Abdulai Ibrahim Abu , Dordaa Felix
Published: October 2023

In recent times, what is common in the scientific literature is findings showcasing the environmental and social menaces associated with artisanal and small-scale mining (ASM)–low-tech, low capital investment, and labor-intensive mineral extraction and processing. However, a better understanding of how ASM shapes livelihood and rural economies may present nuances as to how its negative ramifications can be addressed. As a result, this paper examines how galamsey engenders livelihoods and the transformation of rural economies in Ghana. We produced a nuanced counter-debate to the widely held view that galamsey is evil and a menace to national development by sourcing data from 236 operators using a questionnaire and key informant interviews with 11 relevant stakeholders in north-western Ghana. Findings show that galamsey is a source of employment, income, and accumulation of assets such as houses, motorbikes, cars, and filling stations, which together make the local economy thrive, thereby fostering a local economic boom. However, there is limited collaboration between regulatory agencies and local stakeholders in implementing sustainable mining policies in Ghana. To address this problem, the government should engage local community actors such as the chiefs and landlords, assembly members, and the lead miners on possible steps to streamline and effectively monitor galamsey operations as opposed to military clamp downs.

Published: October 2023

One method that can be used to improve soil properties is the addition of geopolymer cement to the soil to become more stable. This study aimed to determine the effect of geopolymer cement on soil stability. The raw materials for geopolymer cement include clay and basalt rock, with variations in the composition of 0%, 20%, 30%, 40%, and 50%. The levels of temperature variance used were 40 oC, 60 oC, and 80 oC, with variations in 4 and 6 hours. Characterization includes X-ray fluorescence (XRF), X-ray diffraction (XRD), and scanning electron microscope (SEM) tests of raw materials and products. The highest compressive strength was obtained on a mixture of 40% basalt, 200 mesh, and a heating temperature of 80 °C for 6 hours, 56.32 MPa. The California Bearing Ratio (CBR) test showed a significant increase in the heat treatment geopolymer products. The CBR value on y1 during the 10x collision was 16.67%; in the 30x crash, it increased to 63.33%, while in the 65x collision, it increased to 78.33%.

Neste trabalho foram avaliadas as principais causas de condenação de fígado bovino na inspeção post mortem, a partir do levantamento de dados, em um abatedouro-frigorífico situado no Estado do Espírito Santo, sob Serviço de Inspeção Federal (SIF). Para realização do levantamento, utilizou-se as fichas oficiais do Serviço de Inspeção Federal (SIF) referentes ao abate mensal de bovinos e suas respectivas condenações hepáticas durante o ano de 2022. Foram abatidos 45.482 bovinos nesse período, sendo 43.578 machos (95,81%) e 1.904 fêmeas (4,19%). Ao total, 4.365 fígados foram condenados, sendo uma frequência de 9,6% do total de animais abatidos. Três afecções foram as mais recorrentes: os abscessos hepáticos que totalizaram 1.357 condenações (31,1%), seguidos pela peri-hepatite e pela fasciolose, responsáveis por 546 (12,5%) e 518 (11,9%) condenações, respectivamente. As três lesões mais frequentes citadas somaram 55,5% das condenações de fígados bovinos. Também foram detectadas outras causas de condenação, como contaminação gastrointestinal e biliar, que obteve o total de 924 casos (21,2%), além de 514 casos de teleangiectasia (11,8%), 505 casos de cirrose (11,6%) e 1 caso de alteração linfática (0,001%). O prejuízo econômico devido às condenações hepáticas foi substancial para a indústria, totalizando uma média de R$ 41.467,50, no decorrer do ano de 2022. Dessa forma, torna-se imprescindível a diminuição de afecções hepáticas, identificando suas principais causas e possíveis soluções, a fim de minimizar perdas econômicas para a indústria.

O câncer pancreático é diagnosticado com baixa frequência em gatos, tendo como diagnósticos diferenciais pancreatites e adenomas. Foi atendido uma gata de 3 anos de idade, sem raça definida, com hiporexia, prostração e dor epigástrica. Pelo ultrassom de abdome observou-se uma formação sólida e contornos irregulares em região hipogástrica direita, vascularização ao doppler, sem plano de separação com duodeno e efusão abdominal. Foi realizada a Tomografia Computadorizada, onde confirmou-se a presença de área tumoral de 9 cm caudal ao processo caudado do lobo hepático, em íntimo contato com as veias esplênica e porta. A paciente foi submetida a pancreatectomia parcial para diagnóstico morfológico e alívio. O material extraído foi fixado em formaldeído e o diagnóstico morfológico inicial foi carcinoma indiferenciado padrão sólido. Posteriormente, realizou-se a imuno-histoquímica para definição da histogênese, sendo positivo para os marcadores AE1AE3, CDX2, CK8 ̸ 18, CK20 e Ki67 para prognóstico, que favoreceram carcinoma pancreático sólido acinar, com 80% das células em divisão celular. Iniciou-se o tratamento com quimioterapia adjuvante doxorrubicina e carboplatina alternadas a cada 28 dias. Após 4 meses de tratamento a paciente ganhou peso, se manteve ativa, com normorexia, mas verificou-se recidiva tumoral com carcinomatose em peritôneo. Foi associada a quimioterapia metronômica com prednisona diariamente e ciclofosfamida em dias alternados. O tratamento instituído foi bem tolerado pela paciente e parece ser uma opção no controle desse tipo de doença. O baixo número de diagnóstico e escassez de informações nas literaturas, limitam as opções de tratamento e possibilidades terapêuticas. O adenocarcinoma pancreático acinar é de ocorrência rara entre os felinos, com grandes chances de metástase e sobrevida de dias a poucos meses após o diagnóstico.

O hemangiossarcoma é uma neoplasia maligna comum em cães, pouco comum em felinos e que confere um prognóstico de reservado a ruim nos pacientes acometidos com a forma visceral, e favorável naqueles que desenvolvem a forma cutânea da doença. O exame histopatológico é essencial para o diagnóstico definitivo, assim como os exames de imagem para delimitação da área tumoral, avaliação das margens cirúrgicas e pesquisa de metástases. O tratamento de escolha é a remoção cirúrgica, que pode ser associada a quimioterapia e a radioterapia. Este trabalho teve como objetivo relatar um caso incomum de hemangiossarcoma muscular em uma paciente canina, que foi tratada através de exérese tumoral, sendo realizado técnicas reconstrutivas para reparo da parede abdominal com omento, tela de polipropileno e transposição do músculo reto abdominal.

This research aims to find out how the Legal Lending Limit (LLL) is implemented for commercial banks. The method used in this research is a normative legal research method using a statutory approach. The research results show that the application of the Legal Lending Limit (LLL) is a form of application of the precautionary principle where regulations regarding LLL aim to minimize credit risks that may occur. If there is a violation or exceedance of the LLL, it must be handled immediately by making an action report and the bank must resolve the violation or exceedance of the LLL in accordance with the action plan within a predetermined time limit. The impact of violations or exceeding the LLL that are not resolved means that the person responsible for a bank can be subject to sanctions in the form of administrative sanctions and criminal sanctions, apart from that it can also have an impact on the continuity of the bank's existence if a credit failure occurs.
