MODELING OF THE COMMERCIAL VOLUME STOCK IN AN OMBROPHILOUS FOREST IN THE SOUTHWEST OF THE AMAZON
Authors: Cysneiros Vinicius Costa , Machado Sebastião do Amaral , Pelissari Allan Libanio , Figueiredo Filho Afonso , Urbano Edilson
Published: March 2017

ABSTRACT The abundance of tree species in tropical rainforests with different shapes and dimensions, as well as the great structural diversity, makes difficult the employment of form factors or equations to estimate individual volumes. However, the employment of equations at the population level makes possible to predict the volumetric stock per unit of area from forest attributes, excluding the necessity of individual tree volume evaluation. Thereby, the aim of this study was to select variables, fit statistical models and propose stand equations to estimate total and exploitable commercial volumes in an Amazon forest under concession regime. For this, variables commonly measured, like density and basal area, were inserted on traditional commercial volume models; besides the application of variables that considered the diversity and forest structure on models generated by the Stepwise process. After analysis, it was observed that the models obtained through Stepwise propitiated more precise estimation of the volumetric stock, reducing estimation errors and reducing problems with heteroscedasticity of residuals. The insertion of variables that express diversity and forest structure on the equations, like Shannon’s and diametric variation indices and the commercial trees ratio, contribute to predictions’ improvement, especially for the exploitable commercial volume, being recommended for the precise evaluation of timber potential of areas under Amazon forest concession.

Authors: Mohammadi Hossein , Mirmehdi Seyedmohammad , Hugen Lisiane Nunes
Published: March 2017

ABSTRAT Thermoplastic composites made with 45, 60 and 75% of rice straw as filler and two types of thermoplastics, virgin polyethylene (PE) and polypropylene (PP) were evaluated. The final boards were made with and without maleic anhydride modified polypropylene (MAPP) at 2% of the total weight of each specimen. The flexural and tensile strengths were measured for dry composites and also measured after 24 h of water immersion of the composites (wet condition). By increasing the filler content, the flexural and tensile strengths and also the density of the specimens decreased. The type of matrix (PE or PP) did not affect significantly the flexural strength, but PP led to higher values of tensile strength for low fiber loadings (45% and 60%). Coupling agents increased the flexural and tensile strength. After water immersion, modulus of elasticity and modulus of rupture were decreased, while tensile strength was less influenced.

Published: March 2017

Abstract Introduction: Adiposity is defined as the accumulation of energy reserves within the adipose tissue at specific body sites. Low-frequency electrical stimulation elicits lipolysis. When applied by insertion of needles into the dermis-hypodermis junction, it leads to a modification of the interstitial space, favoring metabolic changes and lipolysis. Objective: To investigate the effects of electrical stimulation on body fat localized to the abdomen and flanks. Methods: Randomized, controlled clinical trial consisted of two groups of women with body fat localized to the abdomen and flanks. The intervention group (IG) was made up of 9 women (± 24,77 years) who received ten sessions of electrical stimulation, whereas the control group (CG) was made up of 7 women (± 21,8 years) who did not receive electrical stimulation. Perimetric, adipometric and thermographic data were collected before and after the intervention. Data were analyzed using the Shapiro-Wilk test, t test, one-way ANOVA. The significance level was set at p < 0,05. Results: There were statistically significant differences between the intervention and control groups in the assessment immediately following intervention (IG: 33.08 ± 1.00; CG: 30.83 ± 1.5; p = 0.002), 15 minutes following intervention (IG: 33.05 ± 0.48; CG: 30.40± 1.24; p < 0.0001) and at the endpoint (IG: 32.22 ± 14.20; CG: 30.53 ± 1.34; p=0.005) for the thermographic data. For the anthropometric variables, there were no statistically significant differences before and after treatment. Conclusion: Electrical stimulation evokes a significant increase in the temperature of the subcutaneous tissue.

Abstract Introduction: Recovery and maintenance of patients suffering from heart and respiratory diseases using the cardiopulmonary rehabilitation program (CPRP) help maintain their functionality and improve the activities of daily living (ADLs) carried out according to their functional limitations. Objective: To investigate the efficacy of a CPRP in a patient with cardiopulmonary disease, following a 5-month training program. Methods: A 66-year-old female patient, body weight 78 kg, height 1.55 m, diagnosed with acute myocardial infarction and bronchial asthma underwent a six-minute walk test (6MWT) to measure exercise tolerance; the Wells Bench was used to measure the flexibility of the posterior chain and lower limbs (LL), and a hand-held dynamometer (HHD) was used to measure upper limb strength (ULS).Vital sign measurements include blood pressure (BP), heart rate (HR), respiratory rate (RR), oxygen saturation (SpO2) as well as dyspnea and LL fatigue (modified Borg scale) at rest, during and after 5-month CPRP. Results: An increase of 145 meters during the cardiopulmonary rehabilitation program i.e. 30% of walk distance (WD) in the 6MWT (pre = 345, post = 490m). There was an increase of 32% in flexibility (pre = 13, post = 19cm); in right upper limb (pre = 26, post = 60 kgf) and left lower limb strength (pre = 28, post = 72kgf), there was an increase of 57% and 61%, respectively. Conclusion: The CPRP proved to be effective in increasing exercise capacity, upper limb strength and flexibility of the posterior chain and lower limbs.

GFR Evaluation in Living Kidney Donor Candidates
Authors: Levey Andrew S. , Inker Lesley A.
Published: March 2017

Evaluation of GFR, required in the evaluation of living kidney donor candidates, is now receiving increasing emphasis because recent data demonstrate increased risk of kidney disease after donation, including a small increase in the risk of kidney failure. The international guideline development group, Kidney Disease Improving Global Outcomes, recently published a comprehensive set of recommendations for living donor evaluation, with three recommendations regarding GFR. (1) Donor candidacy is evaluated in light of long-term risk, in which GFR is one of many factors. ESRD is considered a central outcome, and a method for estimating long-term risk of ESRD in donor candidates is described. (2) Two GFR thresholds are used for decision-making: a high threshold (≥90 ml/min per 1.73 m2) to accept and a low threshold (<60 ml/min per 1.73 m2) to decline, with 60–89 ml/min per 1.73 m2 as an intermediate range in which the decision to accept or decline is made on the basis of factors in addition to GFR. (3) GFR is evaluated using several methods available at the transplant center, including estimating equations and clearance measurements. We review the rationale for the guideline recommendations, principles of GFR measurement and estimation, and our suggestions for implementation.
The influence of part of speech text structure on eye movements during natural reading
Authors: Malakhova E.Y. , Lamminpiya A.M. , Shelepin Y.E.
Published: March 2017

The difficulty of lexical processing can explain substantial part of variability in fixation duration during the reading process. Factors like word length, frequency, syntactic and semantic ambiguity impact fixation time. On the other hand, there is not much understanding of how saccades parameters vary depending on the text characteristics. Here we investigate how part-of-speech text structure influences eye-movements during the natural reading process. We presented text excerpts from Russian classic literature containing overabundant quantity of verbs, nouns or adjectives to the participants and record their eye-movements during reading. Eye- tracking data was analyzed with the consideration of the individual differences in the reading behavior. We found that saccade length measured in the number of symbols covered per saccade, its duration, average velocity and curve slope differ significantly for texts with different part-of-speech content. This result can provide an evidence of the influence of higher level cognitive processes not only on fixations but also on saccadic movements.

Comparative analysis of stereotypical behavior with hunting in small mammals as an example
Authors: Levenets Y.V. , Panteleeva S.N. , Reznikova J.I.
Published: March 2017

Comparative analysis of stereotypical behavioral patterns including elements of flexible behavior is presented, with hunting behavior of small mammals as an example. Reactions towards live prey (cockroaches) were investigated in rodents possessing different feeding specialization, in comparison with the insectivorous common shrew. Quantitative analysis was used, and Markov chains were constructed to generate schemes of stereotypes of hunting behavior in different species. The characteristic feature of hunting stereotypes in rodents is that after seizing an insect with teeth, they seize and hold it with their forepaws. This is the more evolutionary progressive feature than seizing the prey with teeth only, like shrews do. As schemes of stereotypes and tactics of hunting appeared to be similar in herbivorous narrow-headed voles and granivorous striped field mice, one can assume that these rodents possess specific adaptations to carnivorous life style. Norway rats display the less specialized hunting stereotypes. The studied rodent species demonstrate more primitive hunting stereotypes than specialized hunting rodents; however, their hunting stereotype is rather specific, and this can be considered behavioral adaptation allowing rodents to broaden feeding resources by the use of active hunting towards insects. A suggested scheme of comparative analysis of stereotypical behavior can be used in ethological and psychological studies.

The study was supported by the Russian Science Foundation (grant No. 14-14-00603).

The article contains the results of adaptation and standardization of Russian version of M. Kernis – A. Paradise “The Contingent Self-Esteem Scale” received the translated title “The External Determinants of Self-Attitude Scale”. This scale includes 15 items and is aimed to measure reactivity of self-attitude in relation to external (situational) determinants. The study sample consisted of 440 participants (301 females, 139 males, with a mean age of 18,9 years). The Russian-language version of the technique was verified in terms of internal consistency (Cronbach’s alpha is 0,819), test-retest reliability (after two weeks the Spearman correlation coefficient is 0,805 p<0,01, after four weeks it is 0,782, p<0,01), discriminative ability (Spearman correlation coefficients range from 0,411 to 0,756, p<0,01), external and construct validity. Standardization information is presented as a table for interpretation raw data into stens. The results prove that “The External Determinants of Self-Attitude Scale” is a convenient psychological diagnostic tool and has all the necessary psychometric qualities. Further research steps are associated with standardization within other age groups and refinement of evidence of external and construct validity.

INTEGRASI SAINS DAN AGAMA DALAM PEMBELAJARAN KURIKULUM PAI (Perspektif Islam dan Barat serta Implementasinya)
Authors: Adawiyah Rabiatul
Published: March 2017

The Islamic teachings contain various moral and ethical values which is very important in today's modern era because Islam always concerns with the balance between body and spirit, inward and outward, spiritual and the material, between world and hereafter. Islam can provide moral and ethical values in the development of science. With religion, it is expected that man does not forget himself after successfully developing science, and aware that the science he developed is an ongoing effort within the framework of worship. Therefore, through science, humans will find the ultimate truth that is God. Science is one of the strategic doors to bring people closer to God through intensive and serious effort to consider the universe to the perfection of human life, both physically and spiritually. Through the integration of science and religion developed in PAI (Islamic Education), it is expected to produce the learners who have a scientific attitude, scientific responsibility, capability of utilizing science and become ululalbab.

Published: March 2017

To meet college student needs for financial counseling, it is important to assess why they seek counseling and the extent to which differing financial situations are tied to financial stress. This study examined these issues with a sample of 554 college students who participated in financial counseling and found financial problems in various situations were each linked to increased financial stress. Financial stress was positively associated with having student loans and other forms of debt and was higher for female students and lower for those having investments. From a needs assessment perspective, it is apparent that college students may be able to benefit more from comprehensive financial counseling than from financial advising that is tailored primarily to a single issue.

This study used data from online focus groups collected from November 2014 to April 2015 to understand college students’ decision-making processes when borrowing money to finance their education. Data were collected using an online course management system. Results suggest that (a) students relied heavily on advice from parents, guidance counselors, and friends; (b) attending college was not possible without student loans; and (c) students knew very little about the loans they would be responsible for repaying. Recommendations for financial educators and counselors to help student borrowers make prudent decisions about education debt are presented.
Intergenerational Reflections on Birth: Story as a Method to Enhance Meaning Making in Prelicensure Nursing Students
Authors: Burgess Adriane L.
Published: March 2017

Stories have been used as a way to educate and inform. An educational activity was created for use with prelicensure nursing students in a maternal infant health course where students had the opportunity to be present to the birth stories of older adults. These stories were transformative and brought new context to how the students understood current-day labor and birth practices. This activity allowed students to see how powerful the birth process is in a woman’s life, in that these memories had the power to transcend time. Students were also able to build relationships and practice their communication skills with older adults, which in turn may also be beneficial for the older adults as well.

Published: March 2017

We evaluated a patient education pamphlet on vaginal birth after cesarean (VBAC). Focus groups with 17 women in 4 communities involved a 5-item knowledge pretest and question on intention to plan VBAC, reading the pamphlet, a knowledge posttest, and a moderated discussion. Forming a preference for birth after cesarean was characterized by (a) consolidating information from social sources, (b) seeking certainty in your next birth, and (c) questioning your ability to have a vaginal birth. Participants preferred vaginal birth, but all feared the uncertainty of labor. Knowledge scores increased for all participants, but intentions to plan a VBAC did not change. Our findings may encourage the development of interventions to reduce women’s fear of vaginal birth.

Published: March 2017

La literatura periodontal contiene numerosas descripciones de procedimientos quirúrgicos diseñados para el recubrimiento radicular en dientes con recesión gingival, basados en injertos autógenos provenientes del paladar o de la tuberosidad. Actualmente, existen otras alternativas que disminuyen la morbilidad postoperatoria con buenos resultados funcionales y estéticos mediante el uso de matriz dérmica acelular (MDA) y matriz de colá- geno porcino (MC), las cuales han venido siendo probadas en multiples ensayos clinicos. En la presente serie de casos se describen dos técnicas de recubrimiento radicular para recesiones múltiples utilizando MDA y MC. Se reportan dos pacientes: un primer caso con problemas estéticos en el sector anterosuperior debido a recesio- nes gingivales y restauraciones en mal estado que recibió MDA (AlloDerm ®). El segundo paciente presentaba sensibilidad en el sector anteroinferior además de escasa cantidad de encía queratinizada , la cual recibió MC (Mucograft®). Se obtuvieron resultados favorables en ambos casos demostrando buenos resultados clínicos en el recubrimiento de recesiones gingivales múltiples; considerándolos como una buena alternativa frente a los injertos gingivales autógenos.

Published: March 2017

Los caninos maxilares son unos de los dientes que se impactan con mayor frecuencia en el arco dentario después de los terceros molares. Las impactaciones palatinas son más prevalentes (85%) que las vestibulares (15%).  A pesar de que la incidencia de impactación es de 1 en 100, este rango suele ser mayor en pacientes que buscan tratamientos ortodónticos alcanzando el 23,5%. Resulta sumamente importante definir sus características ana- tómicas, posición, angulación y relación con los dientes vecinos y estructuras adyacentes en la fase diagnóstica. Los primeros protocolos de evaluación fueron realizados utilizando imágenes bidimensionales, sin embargo, con el creciente desarrollo tecnológico, actualmente contamos con imágenes tridimensionales que según la literatu- ra brindan ventajas sobre las imágenes tradicionales. Es así como ya se han desarrollado protocolos utilizando tomografías volumétricas.Desafortunadamente, todos los métodos disponibles en múltiples publicaciones se encuentran dispersos, por lo que propósito de esta revisión es recopilar evidencia científica relacionada con los métodos diagnósticos más utilizados en la evaluación de imágenes para optimizar el plan de tratamiento y pro- nóstico de caninos maxilares impactados.

Published: March 2017

La necrosis pulpar en dientes con ápice abierto representa un desafio al tratamiento endodóntico. Esto debido a que la anatomía radicular se encuentra parcialmente formada, con ápices abiertos, paredes radiculares finas y frágiles, así como la longitud radicular reducida. En estas situaciones, cuatro opciones de tratamiento están disponibles: 1) Apexificación con renovación periódica de medicación intraconducto (MIC), hasta que sea po- sible observarradiográficamente el cierre apical; 2) Apexificación sin renovación de MIC; 3) Confección de una barrera apical utilizando agregado de trióxido mineral (MTA) o Biodentine; 4) Revascularización pulpar. El endodoncista debe estar atento a la evolución tanto de las técnicas de tratamiento como de los materiales den- tales, conociendo sus indicaciones y limitaciones. Este artículo llevó a cabo una revisión de la literatura sobre las diferentes formas de tratamiento en casos de dientes traumatizados con rizogénesis incompleta y necesidad de tratamiento endodóntico por necrosis pulpar, indicando las ventajas, desventajas y limitaciones de cada una.

Two-Phase Time Synchronization-Free Localization Algorithm for Underwater Sensor Networks
Authors: Luo Junhai , Fan Liying
Published: March 2017

Underwater Sensor Networks (UWSNs) can enable a broad range of applications such as resource monitoring, disaster prevention, and navigation-assisted. It is especially relevant for sensor nodes location in UWSNs. Global Positioning System (GPS) is not suitable for using in UWSNs because of the underwater propagation problems. Hence some localization algorithms based on the precise time synchronization between sensor nodes have been proposed which are not feasible for UWSNs. In this paper, we propose a localization algorithm called Two-Phase Time Synchronization-Free Localization Algorithm (TP-TSFLA). TP-TSFLA contains two phases, namely, range-based estimation phase and range-free evaluation phase. In the first phase, we address a time synchronization-free localization scheme base on the Particle Swarm Optimization (PSO) algorithm to decrease the localization error. In the second phase, we propose a Circle-based Range-Free Localization Algorithm (CRFLA) to locate the unlocalized sensor nodes which cannot obtain the location information through the first phase. In the second phase, sensor nodes which are localized in the first phase act as the new anchor nodes to help realize localization. Hence in this algorithm, we use a small number of mobile beacons to help achieve location without any other anchor nodes. Besides, to improve the precision of the range-free method, an extension of CRFLA by designing a coordinate adjustment scheme is updated. The simulation results show that TP-TSFLA can achieve a relative high localization ratio without time synchronization.

Ti and its alloys are the most commonly used materials for biomedical applications. However, bacterial infection after implant placement is still one of the significant rising complications. Therefore, the application of the antimicrobial agents into implant surfaces to prevent implant-associated infection has attracted lots of attention. Scientific papers have shown that inorganic antibacterial metal element (e.g. Ag, Cu, Zn) can be introduced to implant surfaces with the addition of metal nanoparticles or metallic compounds into electrolyte via micro-arc oxidation (MAO) technology. In this review, the effects of the composition and concentration of electrolyte and process parameters (e.g. voltage, current density, oxidation time) on morphological characteristics (e.g. surface morphology, bonding strength), antibacterial ability and biocompatibility of MAO antimicrobial coating were discussed in detail. Anti-infection and osseo-integration can be simultaneously accomplished with the selection of the proper antibacterial elements and operating parameters. Besides, MAO assisted by magnetron sputtering (MS) to endow Ti-based implant materials with superior antibacterial ability and biocompatibility was also discussed. Finally, the development trend of MAO technology in the future was forecasted.
Fabrication of Polymeric Antireflection Film Manufactured by Anodic Aluminum Oxide Template on the Dye-Sensitized Solar Cell
Authors: Tsai Jenn-Kai , Tu Yu-Shin
Published: March 2017

In this study, a high energy conversion efficient dye-sensitized solar cells (DSSC) was successfully fabricated by attaching a double anti-reflection (AR) layer which is composed of a subwavelength moth-eye structured polymethyl methacrylate (PMMA) film and a polydimethylsiloxane (PDMS) film. The efficiency is up to 6.79%. The moth-eye structured PMMA film was fabricated by using anodic aluminum oxide (AAO) template which is simple, low-cost and scalable. The nano-pattern of AAO template has been precisely reproduced onto PMMA film. The photoanode is composed of Titanium dioxide (TiO2) nanoparticles (NPs) with diameter of 25 nm deposited on the fluorine-doped tin oxide (FTO) glass substrate and the sensitizer N3. The double AR layer can effectively improve the short-circuit current density (JSC) and conversion efficiency from 14.77 to 15.79 mA/cm2 and from 6.26% to 6.79%, respectively.
Beyond Academia: Indigenous media as an intercultural resource to unlearn nation-state history
Authors: Lehman Kathryn
Published: March 2017

This article proposes that settler communities cannot teach or understand our shared intercultural history without listening to ideas presented by Indigenous communities about their own history in lands currently occupied by modern nation- -states. This history enables us to understand the power of the ethnographic gaze and its relation to The Doctrine of Discovery (1493), which extinguished Indigenous rights to lands and resources, rights later transferred to the modern nation- -states through the legal notion of “eminent domain”. These rights include the ownership of intangibles such as the image and storytelling through photography and film. Maori scholars Linda Tuhiwai Smith, Barry Barclay and Merata Mita are cited on knowledge production, copyright and image sovereignty to decolonise our understanding of the right to self-representation. The study includes a brief analysis of films that help decolonise an ethnographic gaze at these relationships, particularly the Brazilian documentary “O Mestre e o Divino” by Tiago Campos Torre (2013).Keywords: Indigenous peoples. Nation-state history. Film. Self- -determination.
Imagens, narrativas, culturas infantis em “Abril despedaçado”: tateando um modo de olhar
Authors: Vasconcelos Michele de Freitas Faria de , Melo Marcos Ribeiro de , De Morais Oliveira Roselusia Teresa
Published: March 2017

Esse texto busca experimentar um modo de olhar e narrar infâncias, percorrendo alguns (des)caminhos conceituais-metodológicos. A aposta é na possibilidade de com o cinema produzir imagens, dizibilidades e visibilidades, que criem conexões com forças de um pensamento intempestivo, numa tentativa de desnaturalizar verdades sobre ‘a’ infância veiculadas no (nosso) tempo. Inspiradas/o no método da etnografia de tela, analisamos o filme “Abril despedaçado”, exercitando uma ética da alteridade da infância. Para isso, tateamos falas e gestos dispersos no campo-tela da personagem “menino”. Acompanhamos seu percurso político-afetivo de borramento de (nossos) fazeres, saberes e poderes sobre culturas infantis a desencaminhar modos humanos de produzir relações consigo, com o ‘outro’ e com o mundo.Palavras-chave: Infâncias. Cinema. Etnografia. Imagem. Narrativa.
Registros híbridos: uma análise da estrutura dos filmes “O som ao redor” e “Recife frio”, do diretor Kleber Mendonça Filho
Authors: Japiassú de Queiroz Carlos Eduardo , Carneiro da Cunha Nóbrega Maria de Lourdes
Published: March 2017

O objetivo deste trabalho é realizar uma abordagem dos filmes “O Som ao Redor” e “Recife Frio”, do cineasta brasileiro Kleber Mendonça Filho, produzidos em 2013 e 2009, respectivamente. Os filmes expõem a problemática da transformação urbana da cidade de Recife, capital do estado de Pernambuco, na região Nordeste do Brasil. Deste modo, nossa análise objetivará nos filmes a construção de sua estrutura narrativa, assim como a proposta de seu conteúdo representacional. Outrossim, afirmamos o ponto de vista de que se tratam de obras que miscigenam os gêneros ficcional e documental de forma bastante original e criativa. Por fim, observamos que tais filmes receberam vários prêmios e menções honrosas em diversos festivais de cinema, tornando-se exemplares do denominado Cinema Pernambucano, o qual tem se colocado de grande importância no conjunto do Cinema Brasileiro nas últimas três décadas.Palavras-chave: Teoria do Cinema.

Cinema brasileiro contemporâneo e a juventude de classe média urbana: um olhar prospectivo
Authors: Bomfim Oliveira Rodrigo
Published: March 2017

O presente texto apresenta alguns temas recorrentes ao campo das representações da juventude no cinema brasileiro contemporâneo. São enfoques apresentados em um conjunto de filmes da ultima década – aqui sendo evidenciado por um olhar prospectivo tendo como base as obras As melhores coisas do mundo (2010) e Desenrola (2011). Os vieses narrativos dos filmes apresentam formas diversas como os jovens viabilizam suas vidas num contexto de classe média e média alta urbana. Apresentam as dores e os prazeres de uma faixa etária compreendida por adolescentes, em que a correlação entre a casa (quarto) e a rua (escola) alcançam o tom das sociabilidades do referido grupo social, mediada por códigos culturais próprios como hobbies, gírias, músicas, roupas, pedagogias do amor e pelos meios pós-massivos de comunicação, sobretudo pela WEB.Palavras-chave: Cinema. Culturas juvenis. Sociabilidades.

El escritor que se pintó a sí mismo: Los figurines de Álvaro Retana
Authors: TORO BALLESTEROS Sara
Published: March 2017

El propósito de este artículo es analizar las fructíferas relaciones entre literatura y moda en la obra pictórica y literaria del polifacético y no menos carismático Álvaro Retana (1890-1970). Para ello, nos centraremos en su biografía, así como en el estudio y comparativa de sus figurines para espectáculos de varietés con su novela Las locas de postín. Ambos, en apariencia frívolos, ofrecen un enfoque inusitado y progresista de la mujer y de la homosexualidad en la España previa a la Guerra Civil.
New Insight on the Polymer Flooding to Mature Fields
Authors: da Silva Ivonete Pereira , Lucas Elizabete Fernandes
Published: March 2017

A polymer flooding Pilot in Brazil showed positive results and distinct from other Pilots, in terms of increased oil production and reducing the water produced. These results, however, could not be attributed to viscosity correction - the fundamental principle of the process according to literature -, because the combination of adverse conditions of application, such as high salinity and hardness of the water reservoir, heterogeneity and canalization formation, as well as reduced injected polymer mass. The aim of this work was to reproduce in laboratory scale the phenomenon observed in Pilot. The laboratory flow tests were performed at constant rate in natural porous media, in the range of 100 mD and 1000 mD, and in metallic porous media 60000 mD, at HPAM concentrations of 10 ppm and 1000 ppm, salinity 38000 ppm and temperature 50 °C. The injectivity field test was conducted at concentrations of 300, 500 and 1000 ppm, followed by water injection and monitored with tracers. The residual resistence factor (RRF) as a result of the flow of the HPAM solution at very low concentration (10 mg/L) was much higher than RRF due to the flow of concentrated HPAM solution (1,000 mg/L). As unexpected, in the field, presenting significant finger, the lowest pressure occurred at the highest polymer concentration. The tracer test confirmed the significant decrease in permeability after HPAM injection. Evaluations reported show that the concentration regimes of HPAM dispersions are highly impactful in the flow in porous media, and could be related also to the polymer hydrodynamic volume. As an example, injection of a polymer dispersion of 10 ppm caused a higher factor of residual resistance than the promoted by dispersing 1000 ppm, even at high salinity and high permeability conditions. The results extend our understanding of the mechanisms governing the behavior of polymer dispersions in porous media, particularly in the process of correcting mobility in mature fields.
