Avaliação de território e coremática na compreensão do espaço geográfico

This paper presents the evaluation of territory and chorem representation as complementary theoretical and methodological tools in the analysis of territory. Both contribute to a better understanding of geographic space in the current period. Those rescue the idea of synthesis which is so characteristic of Geography. Something simple, direct and communicative, but that does not obviate the theoretical and methodological rigor. Points to an effort to find better ways to present and represent the organization of geographical space. Este trabalho apresenta a avaliação de território e a coremática como instrumentos teórico-metodológicos complementares no processo de análise do território. Ambos contribuem para uma melhor apreensão do espaço geográfico no período atual. Resgatam a ideia de síntese que é tão característica da Geografia. Algo simples, direto e comunicativo, mas que não prescinde do rigor teórico e metodológico. Aponta para um esforço em encontrar melhores maneiras de apresentar e representar a organização do espaço geográfico

Resistance of Rice Varieties to \u3ci\u3eSitophilus oryzae\u3c/i\u3e (Coleoptera: Curculionidae)

Abstract Rice, Oryza sativa L. (Poaceae), is one of the world’s most important food crops. Among the insects that damage rice grains, the rice weevil, Sitophilus oryzae (L.) (Coleoptera: Curculionidae), is the most important species. The objective of this study was to identify rice varieties with resistance to S. oryzae as measured by grain feeding damage and S. oryzae reproduction. The rice varieties evaluated were obtained from the germplasm bank of the National Center of Research Rice and Beans, Embrapa, Brazil. The experimental design was completely randomized with 3 replications and 22 treatments (varieties). The varieties Bonança, Esmeralda, and Rio Verde had the antibiosis and/or antixenosis type of resistance, providing high rates of mortality, low rates of adult emergence, and low rates of grain consumption by S. oryzae. The varieties Pepita and Progresso were susceptible, with a high rate of S. oryzae adult emergence and grain consumption. The presence or absence of a fissure in the grain was a major morphological characteristic determining susceptibility or resistance to S. oryzae in rice varieties. Resumo O arroz (Oryza sativa L.; Poaceae) é uma das culturas alimentares mais importantes do mundo. Entre os insetos que danificam os grãos de arroz, o gorgulho do arroz Sitophylus oryzae L. (Coleoptera: Curculionidae) é a espécia mais importante. O objetivo deste trabalho foi identificar variedades de arroz com resistência a S. oryzae. As variedades de arroz avaliadas foram obtidas do banco de germoplasma do Centro Nacional de Pesquisas em Arroz e Feijão, EMBRAPA, Brasil. O delineamento experimental foi inteiramente casualizado com 3 repetições e 22 tratamentos (variedades). As variedades Bonança, Esmeralda e Rio Verde apresentaram resistência do tipo antibiose e/ou antixenose, tendo altas taxas de mortalidade, baixas taxas de emergência de adultos e baixo consumo de grãos por S. oryzae. As variedades Pepita e Progresso são suscetíveis com alta emergência de adultos e consumo de grãos por S. oryzae. A presença ou ausência de fissuras no grão é uma importante característica morfológica para determinar a susceptibilidade ou resistência a S. oryzae em variedades de arroz

Prevalence of mutans streptococci isolated from complete dentures and their susceptibility to mouthrinses

The aims of this study were to evaluate the incidence of mutans streptococci (MS - sessile form) on complete maxillary dentures after use of a specific denture paste, and to determine the minimum inhibitory concentration (MIC) and maximum inhibitory dilution (MID) of 3 oral mouthrinses: Cepacol, Plax and Periogard. Seventy-seven complete denture wearers were randomly assigned into 2 groups, according to the product used for denture cleaning: Control group - conventional dentifrice (Kolynos-Super White); and Test group: experimental denture cleaning paste. Denture biofilm was collected at baseline and after 90 and 180 days after treatment by brushing the dentures with saline solution. After decimal serial dilution, samples were seeded onto agar sucrose bacitracin to count colonies with morphological characteristics of MS. MS identification was performed by the sugar fermentation tests. After this procedure, brain heart infusion broth (BHI) was added to oral mouthrinses (Plax, Cepacol e Periogard) and seeded on Petri dishes. The colonies were seeded using the Steers multiplier and, after the incubation, the MIC and MID of the mouthrinses were calculated. The results showed an incidence of 74.0% (n=57) of MS in the 77 complete dentures examined in the study, being 76.3% (n=29) of the Control group (conventional dentifrice) and 71.8% (28) of the Test group (experimental denture cleaning paste). In both groups, the number of positive cases for MS decreased from day 0 to day 180. In the Test group there was a slight decrease in the incidence of Streptococcus mutans 90 days after use of the experimental denture cleaning paste, which was not observed in the Control group. As regards to mouthrinses, for both groups, Periogard showed antimicrobial action with the highest dilution, followed by Cepacol and Plax. In conclusion, the incidence of MS in complete dentures was high and Periogard was the mouthrinse with the strongest antimicrobial action against MS. The experimental denture cleaning paste showed a slight action against S. mutans after 90 days of treatment.O objetivo deste estudo foi avaliar a incidência de estreptococos do grupo mutans (forma séssil) de próteses totais superiores após o uso de uma pasta específica para higienização de próteses totais, bem como determinar a concentração inibitória mínima (CIM) e diluição inibitória máxima (DIM) de 3 enxaguatórios bucais: Cepacol, Plax e Periogard. Setenta e sete usuários de próteses totais foram distribuídos em 2 grupos: (A) grupo Controle: dentifrício convencional (Kolynos Super Branco) e (B) grupo Teste: pasta experimental para higiene de próteses (1). O biofilme das próteses foi coletado no início e após 90 e 180 dias dos tratamentos, por meio de escovação das próteses com solução salina. Após a diluição decimal seriada, as amostras foram semeadas em agar sacarose bacitracina para a contagem de colônias características de estreptococos do grupo mutans. A identificação dos estreptococos do grupo mutans foi realizada por meio de testes de fermentação de açúcares. Após este procedimento, o caldo de infusão de cérebro e coração (BHI) foi adicionado aos antissépticos (Plax, Cepacol e Periogard) e semeado em placas de Petri. As colônias foram semeadas usando o mutiplicador de Steers e após a incubação, a concentração inibitória mínima e a concentração inibitória máxima dos enxaguatórios foram calculadas. Os resultados mostraram que a incidência de estreptococos do grupo mutans nas 77 próteses totais examinadas foi de 74,0% (n=57), sendo 76,3% (n=29) do grupo Controle (pasta convencional) e 71,8% (n=28) do grupo Teste (pasta experimental). Em ambos os grupos, o número de casos positivos para estreptococos do grupo mutans diminuiu, do início (0 dias) para 180 dias. Houve uma pequena diminuição da incidência de Streptococcus mutans após 90 dias do uso da pasta experimental, o que não foi observado no grupo controle. Com relação aos enxaguatórios, para ambos os grupos, o Periogard apresentou atividade antimicrobiana com diluições maiores, seguido do Cepacol e Plax. Pôde-se concluir que a incidência de estreptococos do grupo mutans em próteses totais foi elevada e que o Periogard foi o enxaguatório com melhor ação antimicrobiana contra os estreptococos do grupo mutans. A pasta experimental mostrou uma pequena ação contra S. mutans após 90 dias de tratamento

What influences the implementation of IFRS for SMEs? The Brazilian case

We investigate factors influencing the implementation of IFRS for SMEs in Brazil. Accountants and accounting firms from all over the country received a questionnaire about the perceptions of IFRS for SMEs. A Logit regression on the factors associated with non-implementation using 426 valid observations suggests that inconsistencies and incomprehensibility issues are the main factors preventing implementation. However, further investigation indicates that once participants know the standard, “implementation myths” are mitigated. Therefore, regulators should increase the availability of education programs, so accountants feel more secure and boost the standard’s implementation. We complement the findings of IASB’s Second Comprehensive Review of the standard

Isometry of Potential Attachment Sites for the Iliotrochanteric Suture in Dogs: an ex vivo Study

Background: Coxofemoral luxation is the most common traumatic luxation in dogs and the iliotrochanteric suture is one of the surgical treatment options. The orthopedic suture aimed at surgically restoring joint movement should be employed in an isometric manner in order to maintain adequate tension throughout the arc of motion. This study aimed to determine the isometric points for the iliotrochanteric suture in dogs during the joint extension and flexion movements. This evaluation was performed both in the intact hip joint and in the luxation model, establishing the best combination, among the determined points, for the reestablishment of normal joint movement.Materials, Methods & Results: Radiographic analyses of 12 canine cadaveric hips, both intact and in craniodorsal luxation model, were performed in a neutral position, flexion at 50°, and extension at 150°. In the trochanteric segment, two parallel lines were drawn, creating the central vertical axis and the secondary vertical axis. Three points were then determined on each axis, from proximal to distal, corresponding to 25, 50, and 75% of the height of the axis, and were labelled as T1, T2, and T3 and T4, T5, and T6, respectively. In the iliac segment, a line perpendicular to the longitudinal axis of the ilium was drawn, and 25, 50, and 75% of this height corresponded to points I1, I2, and I3, respectively. The lengths between the points were measured, with the objective of evaluating which combination of points presented less variation in the joint positions. The central location of the iliac and trochanteric segments, determined respectively by I2 and T2, provided smaller variations during the maximal movements of hip flexion and extension.Discussion: The surgical techniques of iliotrochanteric suture target to maintain the internal rotation of the femoral head inside the acetabulum and abduction of the femur until the soft tissues have healed. The described techniques for the iliotrochanteric suture present a great anatomical variety in the arrangement of the anchor points of the suture. It is known that if during motion, the attachment sites move closer to one another, the suture will become lax and, if the attachment sites move away from one another, the suture will tighten. Therefore, the implantation in isometric sites assists in reducing the variation of the distance between the points of origin and insertion of the suture during joint movement, keeping the suture tension constant and allowing the functional recovery of the joint. This study demonstrates that there are some locations for the origin and insertion of an iliotrochanteric suture that are associated with less length change than others. I2-T2 combination is the point closest to isometry for the iliotrochanteric suture during hip extension and flexion, so that, T2 is the most central point of the greater trochanter, corresponding to 50% of the height of its central vertical axis, as well as I2, which corresponds to the most central point of the ilium, representing 50% of the height of the most caudal portion of its body. The isometric point found by us details the exact location of perforation in all aspects (height and length), both in the ilium and the trochanter. In addition, it is a personalized point created for each patient from its radiographic examination and taking into consideration its anatomical variations, so that there is no damage to the suture during hip extension and flexion movements

Methodological roadmapping: a study of centering resonance analysis

Purpose – This paper aims to map the creation and evolution of centering resonance analysis (CRA). This method was an innovative approach developed to conduct textual content analysis in a semi-automatic, theory-informed and analytically rigorous way. Nevertheless, despite its robust procedures to analyze documents and interviews, CRA is still broadly unknown and scarcely used in management research. Design/methodology/approach – To track CRA’s development, the roadmapping approach was properly adapted. The traditional time-based multi-layered map format was customized to depict, graphically, the results obtained from a systematic literature review of the main CRA publications. Findings – In total, 19 papers were reviewed, from the method’s introduction in 2002 to its last tracked methodological development. In all, 26 types of CRA analysis were identified and grouped in five categories. The most innovative procedures in each group were discussed and exemplified. Finally, a CRA methodological roadmap was presented, including a layered typology of the publications, in terms of their focus and innovativeness; the number of analysis conducted in each publication; references for further CRA development; a segmentation and description of the main publication periods; main turning points; citationbased relationships; and four possible future scenarios for CRA as a method. Originality/value – This paper offers a unique and comprehensive review of CRA’s development, favoring its broader use in management research. In addition, it develops an adapted version of the roadmapping approach, customized for mapping methodological innovations over time

Surgical resection, intraoperative radiotherapy and immediate plastic reconstruction: A good option for the treatment of distal extremity soft tissue sarcomas

AimTo show three patients with soft tissue sarcomas of distal extremities conservatively treated after tumor-board discussion, involving margin-free surgery, exclusive intraoperative radiotherapy, and immediate reconstruction.BackgroundCurrent guidelines show clear and robust recommendations regarding the composition of the treatment of sarcomas of extremities. However, little evidence exists regarding the application of these treatments depending on the location of the primary neoplasia. Tumors that affect the distal extremities present different challenges and make multidisciplinary discussions desirable.Methods/ResultsWe reported 3 patients who were approached with a conservative intention, after tumor board recomendation. The goals from the treatment performed were aesthetic and functional preservation, while enruring locoregional control. We had wound healing complications in 2 of the cases, requiring additional reconstruction measures. Patients are followed up for 24, 20 and 10 months; local control is 100%, and functional preservation is 100%.ConclusionsDespite being a small series, it was sufficient to illustrate successful multidisciplinary planning, generating a therapeutic result with improved quality of life for patients who had an initial indication for extremity amputation
