Sensitivity evaluation of Krakowiec clay based on time-dependent behavior
Authors: Olek Bartłomiej , Dobak Paweł , Gaszyńska-Freiwald Grażyna
Published: December 2018

Time resistance of soil structure in oedometer IL (Incremental Loading) tests was defined by Janbu as specific dependence between load and development of strain during consolidation process. Anumber of laboratory tests have been conducted in order to study the time dependent behaviour of the natural and remoulded clay, thereby providing sensitivity evaluation. The soil sensitivity framework was applied to represent the effect of structure and stress dependency on the time resistance number. For this purpose, the creep behavior of structured and remolded clay during consolidation were compared and the initial amount of bonding (structure) was determined as well. In this study, the initial amount of bonding was defined through the intrinsic time resistance number and lowest measured time resistance number determined by the IL oedometer test conducted on intact (undisturbed) sample. In case of the Krakowiec clay, it was found that the time resistance number varies with effective stress level. The investigated clay indicated medium sensitivity, which is in great agreement with previous reports on the sensitivity of the Krakowiec clay.

Published: December 2018

The aim of the study is the investigation of potentially toxic elements adsorption on limestone, dolomite and marble particles of different size. As parameters, rock particle size, solution concentration, contact time and presence of other elements in the solution have been investigated. Four fractions with different particle size (−4mm + 1mm, −1mm + 315μm, −315μm + 90μm, <90μm) have been studied. Batch experiments have been carried out at 20, 60, 120 min from monoelement and competitive Cd, Cu, Pb, Zn solutions at concentrations 5, 100, 500 mg/L, whereas fixed bed conditions have also been applied. In lower concentrations, adsorption reaches equilibrium after 60 min. 15% difference in Pb adsorption and 15-30% in Zn adsorption has been observed depending on particle size. However, according to Taguchi method particle size has not proven a determinative parameter, so as to make grinding and/or sieving necessary for their further utilisation. Cd and Zn adsorption from a competitive solution is lower, whereas Cu and Pb adsorption is similar. Adsorption capacity of materials rises up to 0.03 mg Cd/g, 0.60 mg Cu/g, 0.03 mg Pb/g, 0.60 mg Zn/g. In fixed bed conditions more than 93% element is adsorbed, of which only 4% is leached.

Published: December 2018

The chromium was deposited on the surface of 0.45 C medium carbon steel by high current pulsed electron beam (HCPEB) alloying treatment to obtain a high quality alloying layer. The microstructure of the alloying layer was studied by X-ray diffraction, optical microscopy, scanning electron microscopy (SEM), and transmission electron microscopy. The hardness of the surface was measured by Vickers durometer. The corrosion resistance of samples before and after HCPEB irradiation was also measured by an electrochemical workstation. The results showed that the alloying layer with a dept of about 4–9 μm on the surface was formed after HCPEB alloying treatment. TEM results revealed that the Cr element is dissolved on the surface and alloyed with C element in the substrate to form Cr23C6enhanced particles. The microhardness and corrosion resistance of the medium carbon steel subjected to a HCPEB alloying processing were remarkably improved compared with the original one.

Authors: Pani Swatirupa , Dash Nilima , Mohapatra B.K. , Singh S.K.
Published: December 2018

Siliceous manganese ore, associated with the banded iron formation occurs in large volume in northern Odisha, India. It is a sub-grade ore containing 21% Mn, 60% SiO2 and 3% Fe, hence do not find any use and considered as waste. Such ore does not respond to any physical beneficiation techniques because of intricate microstructure and poor liberation of Mn-phase. It could only be up-graded to 32% Mn with 36% yield and 52% recovery by processing it through mineral separator followed by WHIMS. Siliceous manganese ore along with calcite and coke in appropriate ratio, when charged to a plasma reactor, a product with slag metal ratio of 2.5:1 was obtained within a period of 10 min. Electron probe micro-analysis of the metal confirmed it to be ferrosilicomanganese while the slag constitute of tricalcium silicate (C3S) with around 5% Mn in adsorbed state.

The first cortical circuits: Subplate neurons lead the way and shape cortical organization
Authors: Kanold Patrick O.
Published: December 2018

The cerebral cortex is essential for our sensory experiences and conscious thought. Its neural connections, in particular sensory areas of the cerebral cortex, are shaped and sculpted by our early sensory experiences. Onset of these first sensory experiences of the world mark an important developmental event, enabling our worldy interactions to shape the makeup of our cerebral cortex. These long-lasting effects of early sensory experience are particularly striking in human communication, since early exposure to the mother’s language is required to detect all nuances in the underlying sounds. Early interactions with the world are mediated by a key set of neurons, subplate neurons, which remain part of the developing cerebral cortex until most of them disappear at later stages of development. They play a crucial role in the developing mammalian brain. Here I review the circuitry and functional roles of cortical subplate neurons, focusing on their purpose in the development of primary sensory cortices.
A Dynamic Segregation Test Method for Heavyweight Concrete: Density Variation Method
Authors: Gökçe H. Süleyman , Andiç-Çakır Ö.
Published: December 2018

Several segregation evaluation methods have been developed for concrete; however, none of them have been specially focused on heavyweight concrete, which has more of a tendency toward segregation because of differences in density of paste matrix to heavy aggregate. Thus, for heavyweight concrete, the segregation may be determined by measuring the difference density in a vertical direction. In this study, a simple reliable method, i.e., the density variation method, that considers the variation in vertical layers of the concrete is modeled to assess dynamic segregation of heavyweight concrete. In addition, 35 heavyweight concrete mixtures with high consistency were designed with various mixing parameters, and the results were compared with the model findings. The suggested test method was also compared with a conventional method (column segregation test by wet-sieving), and an equivalent segregation limit was determined. A strong linear relation (R2: 0.86) was found between the density variation method and column segregation test, and a segregation coefficient limit for segregation of heavyweight concrete is recommended as 1.7 %.

Gene expression variation is a major contributor to phenotypic variation in human complex traits. Selection on complex traits may therefore be reflected in constraint on gene expression. Here, we explore the effects of stabilizing selection on cis-regulatory genetic variation in humans. We analyze patterns of expression variation at copy number variants and find evidence for selection against large increases in gene expression. Using allele-specific expression (ASE) data, we further show evidence of selection against smaller-effect variants. We estimate that, across all genes, singletons in a sample of 122 individuals have ∼2.2× greater effects on expression variation than the average variant across allele frequencies. Despite their increased effect size relative to common variants, we estimate that singletons in the sample studied explain, on average, only 5% of the heritability of gene expression from cis-regulatory variants. Finally, we show that genes depleted for loss-of-function variants are also depleted for cis-eQTLs and have low levels of allelic imbalance, confirming tighter constraint on the expression levels of these genes. We conclude that constraint on gene expression is present, but has relatively weak effects on most cis-regulatory variants, thus permitting high levels of gene-regulatory genetic variation.
Seroconversion in Romanian Small Ruminant Populations Exposed at Chlamydophila Abortus and the Risk to Public Health
Authors: BARAITAREANU Stelian , DANES Doina , DAN Marius , DANES Mihai
Published: December 2018

Chlamydophila abortus is an important pathogen of small ruminants, causing reproductive failure manifested through abortion during the last 2-3 weeks of gestation, stillbirth, or delivery of weak lambs or kids, and orchitis and seminal vesiculitis in males. Also, C. abortus is a zoonotic bacteria, involved in influenza-like illness, pneumonia and abortions sometimes with severe complications in humans. The aim of this article is to evaluate the immunological status to C. abortus of Romanian small ruminant populations, geographically isolated, whose spontaneous uncontrolled contact is excluded. This paper is also assessing the risk of humans exposure to contaminated animals and food. The immunological status of the investigatet small ruminants was evaluated using an ELISA commercial kit and the results were analysed in correlation with the history of vaccination and type of animal breeding (traditional/professional farms). According to these results, the exposure of C. abortus is still to consider in traditional breeding farms, but in professional herds the serological tools are useless to uncover the circulation of wild strains, once the immunoprofilactic programs has been implemented. The public health risk relate to the close contact with the infected sheep and goats, common event in the traditional breeding.

Published: December 2018

ABSTRACT Objective: To evaluate elderly patients in a geriatric service, along with their sensory characteristics and their association with clinical aspects. Methods: This was a descriptive longitudinal study. We enrolled 36 healthy participants of both sexes in this study. The following instruments were used and evaluations performed: clinical evaluation, Mini-Mental State Exam, and quantitative sensory testing. Results: During the follow-up, there was reduction of mean corpuscular volume at each evaluation (p < 0.001) and significant increase in mean corpuscular hemoglobin concentration (p < 0.001). There was an increase of the olfactory (p < 0.001), salty (p = 0.024), sour (p = 0.020), bitter (p = 0.001), facial cold (p = 0.019), hand cold (p = 0.004), facial tactile (p < 0.001), hand tactile (p = 0.012) and facial vibration (p = 0.018) thresholds. Previous existing morbidities were associated with sensitivity changes in the individuals in this sample. Conclusion: This longitudinal study suggests that the loss of sensitivity with aging may be associated with the presence of morbidities in elders.

ABSTRACT Objective: To analyze the practice of obstetric nurses operating in a prenatal/delivery/postpartum unit of a university hospital in Mato Grosso and the maternal welfare resulted from the care provided in this scenario. Method: Study with a quantitative approach, carried out in a prenatal/delivery/postpartum unit of a university hospital in Cuiabá, Mato Grosso. The data were collected through the Scale of Maternal Welfare in Delivery Situation 2, and the study included 104 recent mothers in the period from June to September 2016. The data were analyzed in Epi Info version 7. Results: The results indicate that the practice of obstetric nurses is based on the humanization of labor and childbirth, however, the presence of invasive and unnecessary practices in the service did not influence the level of maternal welfare, which was optimum for 76% of the women. Conclusion: The lack of information might make the women less critical and, therefore, influence the evaluation of the care received

ABSTRACT Objective: To describe the evaluation of patients that participated in the National Program for Improving the Access and Quality in Primary Health Care (Programa Nacional de Melhoria do Acesso e da Qualidade na Atenção Básica) for the comprehensive healthcare, the bond and the coordination of care in the country's macro-regions. Method: A descriptive, transversal study, from interviews with 65,391 patients of Primary Health Care, in 3,944 municipalities regarding the use of health services. Results: The professionals seek to solve the patients' problems in their unit (73.1%) but focused mainly on the scope of the appointment (65.6%) and offering care away from the population's reality (69.4%). Difficulties in the rescue of clinical history were referred (50.3%) and in the care performed in other health services (29.2%). Conclusion: The comprehensive health care, the bond and the coordination of care remain challenges to the Primary Health Care in the country, requiring reflections on the implementation of national policies, especially considering the regional diversities in Brazil.

Published: December 2018

ABSTRACT Objective: To analyze the care coordination for the child and adolescent in chronic condition and users planning in the Health Care Network. Method: Qualitative study, conducted with 26 health professionals and managers through Focus Groups. Thematic content analysis was used. Results: Care coordination is fragile, with lack of support from the management, and presence of high turnover of managers and professionals. The limits in the network planning are due to frequent changes in the careflow. Communication between levels of care and lack of counter-referral makes network care unfeasible. Final considerations: There is a need for planning in the Health Care Network and establishment of careflow, as well as the construction of communication channels and tools of referral and counter-referral between professionals and services, for the constitution and integration of the network from the perspective of user-centered care.

Published: December 2018

Resumo A literatura sobre federalismo aponta que a coordenação do governo federal tem papel central para garantir maior consistência às políticas sociais dos governos subnacionais. Este artigo buscou compreender o papel das relações intergovernamentais nas políticas municipais de educação. Apesar de a Constituição Federal determinar a colaboração entre os entes federados, há diferentes modelos de relacionamento entre estados e municípios na política educacional. Esta pesquisa comparou quatro estados - Ceará, Mato Grosso do Sul, São Paulo e Pará - com modelos distintos de relacionamento com o objetivo de identificar seus resultados nas políticas municipais. A análise de questionários e entrevistas semiestruturadas mostra que o tipo de cooperação tem implicações na capacidade institucional e financeira, na coordenação das políticas municipais e na implementação de políticas federais.
The city and the urban as spaces of capital and social struggle: notes on Henri Lefebvre’s enduring contributions
Authors: Misoczky Maria Ceci , Oliveira² Clarice Misoczky de
Published: December 2018

Abstract The argument of this essay is that Lefebvre’s writings contain relevant contributions to understand the contemporary phenomenon of neoliberal urbanism and, at the same time, his politics of the possible can contribute to explain the restless urban struggles and spatial practices of social movements. We value the author’s contribution from a comprehensive perspective, avoiding the usual fragmented way it has been used in the fields of public administration, organization and urban studies. Our reading follows Gadamer’s notion of “the horizon of the question”, which indicates that “we can understand a text only when we have understood the question to which it is an answer”. Accordingly, the question posed asks for the contribution of Lefebvre’s oeuvre to understand contemporary urban processes and to make visible possible futures objectively implied in processes of social struggles.
A direct comparison of the performance of public-private partnerships with that of traditional contracting
Authors: Rodrigues Bruno , Zucco Cesar
Published: December 2018

Abstract This paper assesses the city of Belo Horizonte’s experience building school infrastructure through public-private partnerships (PPPs). Between 2009 and 2015, Belo Horizonte built very similar schools using both PPPs and traditional public contracting (TPC). As the choice of mode of contracting was unrelated to our outcomes of interest, the experience constitutes a quasi-experiment that allows for a simple and direct comparison of PPPs to TPC. We examine construction- and operation-phase outcomes measured using administrative data and a survey of school administrators. We find that schools constructed under the PPP contracting model outperformed those built using TPCs in most outcomes.

Authors: Salata Tiago Medina , Ribeiro Bruno Niemeyer de Freitas , Muniz Bernardo Carvalho , Antunes Lívia de Oliveira , Rosas Heraldo Belmont , Marchiori Edson
Published: December 2018

Abstract Hearing disorders are usually unilateral and are more common in women. They can be congenital or acquired, and hearing loss is categorized as sensorineural, conductive, or mixed. The onset of hearing loss can be progressive or sudden, and it is a common reason for seeking medical attention. In this context, computed tomography and magnetic resonance imaging have assumed critical roles in the search for an etiological diagnosis and in guiding the therapeutic approach. In this pictorial essay, we illustrate the common causes of hearing loss, discussing the possible differential diagnoses and highlighting the most relevant imaging findings.

Published: December 2018

Resumo Atualmente, o número de crianças que crescem em famílias cujas mães são ativas no mercado de trabalho é significativamente superior ao de gerações anteriores. Essa mudança demográfica envolve alterações quanto ao tempo e cuidado materno dedicado aos filhos, podendo afetar suas vidas atuais e prospecções futuras. Por isso, o objetivo desta pesquisa é contribuir para o debate acerca dos efeitos relacionados à participação da mãe no mercado de trabalho e a escolaridade dos filhos, medida pelas horas de trabalho. As estimações são obtidas por meio de variável instrumental como estratégica de identificação para isolar os efeitos causais entre a decisão pelo mercado de trabalho das mães e a escolaridade dos filhos, nas quais as condições do mercado de trabalho local são utilizadas como instrumentos. Entre os resultados, destaca-se que o aumento das horas trabalhadas da mãe reduz o nível educacional deles. Em relação ao diferencial educacional entre os sexos, observa-se que o efeito da mãe trabalhar não é responsável por introduzir diferenciais educacionais entre os sexos.

Published: December 2018

RESUMO: Este artigo busca debater o compromisso social da universidade pública sob a perspectiva da Educação em Direitos Humanos (EDH), identificando alguns desafios que dificultam a concretização da EDH nestas instituições. Metodologicamente, realizou-se uma revisão bibliográfica da literatura científica acerca dos direitos humanos e do ensino superior brasileiro, bem como uma análise das legislações acerca da EDH, buscando compreender como a universidade pública se insere dentro desta temática. Visualiza-se que as universidades públicas ainda precisam enfrentar alguns desafios para que a concretização das propostas da EDH ocorra, tais como os processos de mercantilização da universidade pública e a privatização do ensino superior; a fragilidade da integração entre ensino, pesquisa e extensão; as dificuldades de se estabelecer uma conexão mais sistemática e profícua com os segmentos e classes sociais que se apresentam em situação de vulnerabilidade social e com direitos violados; e as dificuldades na democratização do acesso à universidade.

RESUMEN En el artículo presento resultados de investigación con respecto al impacto que las políticas delineadas por el Estado mexicano, articuladas por el Consejo Nacional de Ciencia y Tecnología (CONACyT) e implementadas por las Instituciones de Educación Superior (IES), tienen en el proceso de formación de investigadores, con especial énfasis en los campos que corresponden a la educación y la psicología. El proceso de investigación se realiza a través de la observación participante, conversaciones con estudiantes y profesores de programas doctorales en los campos de la psicología y la educación y análisis de documentos oficiales en donde se postulan las políticas de investigación y las que refieren a la formación de investigadores en México. Analízanse las políticas planteadas por el Consejo Nacional de Ciencia y Tecnología (CONACyT) con relación a la función de la investigación en México, así como a las orientaciones que realiza a través del Programa Nacional de Posgrados de Calidad (PNPC) diseñado en la última década del siglo XX con la finalidad de garantizar la formación de investigadores con altos niveles de calidad. Aún aprecio el Programa para el Desarrollo Profesional Docente (PRODEP) en su pretensión de organizar a los investigadores en Cuerpos Académicos y garantizar, de esa manera, la productividad científica de los investigadores de las Instituciones de Educación Superior. Cuestiono las políticas del CONACyT con respecto a la formación de investigadores, demostrando la inconsistencia de las mismas y su limitada aportación a la dinámica de calidad del posgrado de calidad.

Authors: Micarello Hilda , Baptista Mônica Correia
Published: December 2018

RESUMO Neste artigo, discute-se a formação de professoras2 da Educação Infantil como mediadoras de leitura literária e as repercussões desse processo formativo nas práticas docentes, com base em dois projetos de pesquisa-ação realizados pelas Universidades Federais de Juiz de Fora e de Minas Gerais. Leitura literária e docência são abordadas numa articulação entre ciência, arte e vida, buscando-se compreender a experiência dos sujeitos com essa prática cultural a partir dessa articulação. A educação literária é percebida na sua complexidade e, consequentemente, como um processo exigente do ponto de vista da formação de professoras como mediadoras e promotoras da leitura literária junto a bebês e demais crianças pequenas. A análise dos dados demonstrou as potencialidades das pesquisas colaborativas no sentido de, a partir de uma análise dos contextos educativos, construir e experimentar, numa parceria entre pesquisadoras e professoras da Educação Infantil, procedimentos e práticas educativas comprometidas com princípios e concepções que consideram a literatura como arte e a educação de crianças pequenas como direito à ampliação das experiências estéticas.
Literatura, literatura para a juventude e valores: da inculcação à interrogação
Authors: Butlen Max
Published: December 2018

RESUMO A literatura sempre foi e continua sendo atravessada pela questão dos valores. Apesar de seu relativo sucesso no século XX, os formalistas e os estruturalistas não conseguiram eliminar essa questão dos valores. Pelo contrário, os trabalhos recentes lhe consagram um lugar cada vez maior (BUTLEN, 2017). Este lugar foi profundamente renovado, especialmente na literatura para a juventude, pois se trata sempre mais decisivamente de passar de uma postura de inculcação de valores a uma didática centrada sobre sua interrogação para combinar formação literária e formação pessoal. Como descrever e explicar essas evoluções? Por que valorizar os corpora e as abordagens que trabalham para combinar ética e estética, para promover enfim uma postura axiológica?

Published: December 2018

Abstract: Crabs of the genus Persephona are intensely captured in shrimp fisheries as bycatch in the Cananéia region off the coast of the state of São Paulo, Brazil. The analysis of the spatial and temporal distribution of Persephona punctata and Persephona mediterranea could provide information about variation in the abundance of these species, as well as the environmental variables affecting their distribution and the existence of a possible habitat partitioning. Using a shrimp fishery boat equipped with double-rig nets, crabs were monthly captured from July 2012 to June 2014 in seven sites: four in the coastal area adjacent to the Cananéia region and three in the Mar Pequeno estuarine area. The abundances of both species were compared according to spatial (among sites) and temporal (years and seasons) scale distribution. A total of 396 individuals of P. punctata and 64 of P. mediterranea were captured. The abundance of both species was higher in the second sampling year (July 2013-June 2014) and in coastal areas; only one individual of each species was captured in the estuarine area due to the low salinity at this location (approximately 27.7‰). The temperature was the environmental variable that most affected the distribution of both species, which was more abundant in warmer periods. The temporal variation in abundance was modulated by temperature, while salinity modulated the spatial distribution of P. punctata and P. mediterranea. The spatial-temporal distribution of both species differered in Cananéia, pointing to a similar use of the environment's resources.

Published: December 2018

Abstract: Pithecopus rusticus is a newly described species, of which information on its natural history, vocalization and tadpole morphology are still lacking. Here, we describe the larval external morphology of P. rusticus from the type locality, in the municipality of Água Doce, state of Santa Catarina, southern Brazil, comparing it with that of other species of the genus Pithecopus and providing information on its natural history. Eggs from two spawns were collected and kept in the laboratory until hatching. The tadpoles of P. rusticus belong to the suspension-rasper guild. At Gosner stage 37, the tadpoles showed: body shape oval in dorsal view and triangular in lateral view; a tooth row formula of 2(2)/3(1); the third lower row six times shorter than others; marginal papillae uniserial, interrupted by a wide dorsal gap and with rounded tips; and a single row of alternate marginal papillae on lower lip. External morphological features were compared with those of other tadpoles of Pithecopus. Observations on the natural history of P. rusticus are also reported.

ABSTRACT Canine Leproid Granuloma Syndrome (CLGS), also known as canine leprosy, is a cutaneous nodular infectious disease caused by Mycobacterium sp.. Despite being reported worldwide, it is still quite unknown and underdiagnosed. Diagnosis may be achieved by cytopathology or histopathology of skin lesions, but identification of the infectious agent is complex, since bacterial in vitro growth is not possible, relying upon molecular techniques such as PCR to confirm Mycobacterium DNA in the sample. We report a CLGS case in Niteroi, Rio de Janeiro state, Brazil, diagnosed by cytopathology and submitted to molecular identification of the agent. PCR amplification of hsp65 gene was performed and revealed 100% genetic homology to M. murphy strain. This is the first CLGS report with molecular identification in Rio de Janeiro state, and this finding should raise awareness about CLGS as a differential diagnosis among granulomatous skin diseases in this region.

RESUMO A cardiomiopatia dilatada é uma doença de caráter crônico, que compromete a função cardíaca, resultando em desequilíbrio da circulação sanguínea e da homeostase corporal do animal. Este relato apresenta a evolução do quadro clínico e o tratamento de cardiomiopatia dilatada em um exemplar cativo de tamanduá-bandeira. O animal apresentou quadro clínico de insuficiência cardíaca e foi submetido a duas baterias de exames laboratoriais e de imagem em um período de três meses. Posteriormente, foi iniciado o tratamento com pimobendan e suplementação de taurina, resultando em resposta positiva e melhora dos sinais clínicos do paciente. Os achados ecocardiográficos do caso foram compatíveis com cardiomiopatia dilatada com sinais evidentes de diminuição progressiva das frações de ejeção, bem como encurtamento e aumento expressivo das câmaras cardíacas, quando se comparou este caso ao de cães de grande porte e animais saudáveis da mesma espécie. O tratamento com inotrópico positivo, suplementação dietética de taurina e diuréticos se mostrou eficiente em controlar os sinais clínicos do animal.

ABSTRACT The objective of this study was to conduct an investigation of Mycoplasma bovigenitalium and Ureaplasma diversum infections in cattle in the microregion of the Ipanema Valley, state of Pernambuco, Brazil. Vaginal swabs were collected from 355 breeding cows in reproductive age and were analyzed by multiplex PCR (mPCR) and culture. An epidemiological investigation of risk factors was performed for Mollicutes. mPCR analysis showed that, 9.29% (33/355) of the cows were positive for M. bovigenitalium and 21.69% (77/355) for U. diversum; coinfection was observed in 2.81% (10/355) of the cows. The microbiological isolation showed, 81.81% (27/33) of Mycoplasma spp. and 24.67% (19/77) of Ureaplasma spp.. The risk factors related to Mollicutes infection identified were semi-intensive breeding system (OR= 4.6), pasture rent (OR= 3.6), non-isolation of animals with reproductive disorders (OR= 3.2), and natural mounting and artificial insemination (OR= 3.5). There was a significant association between Mollicutes infection and abortions in the first gestational third (P= 0.001). This is the first record of M. bovigenitalium and U. diversum infection in cows in the semiarid region of the state of Pernambuco, Brazil. Preventive measures directed to the identified risk factors can decrease the occurrence of Mollicutes in these herds.

ABSTRACT Multiple pelvic fractures can lead to narrowing of the pelvic canal and loss of life quality. Hemipelvectomy, characterized by removal of bone fragments from the pelvis, is considered a rescue therapy. This report describes the technique of caudal partial hemipelvectomy in four cases of obstipation secondary to traumatic pelvic canal narrowing in four dogs, with promising results. All patients had tenesmus and fecal retention. After the procedure, the patients presented immediate normochezia and support of the ipsilateral limb after 10 to 20 days, showing the feasibility of the technique in small animals, providing clinical improvement without walking alterations.
