title: Weed phytosociological in irrigated rice under different cultivation systems and crop rotation intensity

description: ABSTRACT: This research aimed to evaluate the phytosociology of weeds in irrigated rice in different soil management systems and crop rotation intensity. Therefore, two field studies were carried out. Study 1 was conducted in an area that has been cultivated since 1994 with three cultivation systems: direct, pre-germinated and conventional ones. Study 2 was carried out in an experimental area in five Integrated Farming Systems, with crop rotation. Phytosociological evaluations were conducted when rice was fully blooming, in the first study, and when grain filling was ending, in the second study. Pre-germinated system of rice cultivation has predominance of aquatic weeds. Conventional system when compared with direct sowing has lower weed densities. Integrated Agricultural Production Systems with higher intensity of crop rotation have been higher infested of perennial species.

title: Salinity reduces nutrients absorption and efficiency of their utilization in cassava plants

description: ABSTRACT: The objective of this research was to evaluate the influence of salinity on the absorption and utilization of nutrients by cassava. For the study, cassava was submitted to four saline concentrations: 0, 20, 40, and 60mM NaCl. Results showed that the absorption of all nutrients, except nitrogen (N), was reduced by salinity, with highest reduction for potassium (K). However, all nutrients were maintained at concentrations which did not indicate mineral deficiency problem. The abnormal concentration of calcium in the tuberous roots may have been one of the factors that contributed to the lower growth of this organ and of the plant as a whole. Transports of nitrogen, potassium, phosphorus and sulfur from root to the aerial part was higher under salinity treatment. Efficiency in the use of all the nutrients, mainly N, was reduced due to salinity. Given that: (i) the absorption of K was the most impaired, (ii) there was abnormal accumulation of Ca in tuberous roots, and (iii) the efficiency in the use of N was the most affected, it is suggested to prioritize studies on these three issues, as a way to better understand the aspects related to the tolerance/sensitivity of cassava plants to salinity.

title: Archival policy of digital preservation: a study on its applicability in federal public institutions

description: Abstract This article presents part of the results obtained in a master's research on the preservation of the archival documentary heritage of the Southern Spiritist Federation (FERGS), which has developed in the Professional Postgraduate Program in Cultural Patrimony of the Federal University of Santa Maria (PPGPPC/ UFSM). The general objective of the research is to analyze the application of preservation strategies for the elaboration of a Plan of Preservation of the FERGS Archival Documentary Heritage. In order to subsidize this research, it was decided to carry out a data survey that identified archival policies on digital preservation and how it would be effective in the institutions, so that it would be possible to analyze the universe of said institution, FERGS. The result of this data collection, carried out in fifty-five Brazilian public institutions, showed that a good part of them, or about ninety-one percent, does not have an archival preservation digital policy and none of them has a Digital Preservation Plan To implement this policy. This shows that the public policies on digital preservation emanated by the National Archives are not being effectively implemented within the federal public institutions, corroborating the development of actions to improve this scenario.

title: Influence of individual factors in the use of digital libraries: the case of Journals Portal Capes

description: ABSTRACT This article investigated users and non-users of the Capes Portal to identify independent variables that are determinant to use or non-use of the Portal. The methodological procedure adopted was a web survey sent to 14,763 faculty in 17 Brazilian federal universities, which contained questions on personal and professional characteristics, attitudes to printed versus electronic journals and purposes for using the Internet. With regard to personal characteristics the results indicate that sex is not determinant for the use of the Portal while the variable age is. With regard to professional characteristics, evidences are that the variables area of knowledge, university and academic background are determinant to use. The variable geographic region is not presented as a determinant variable for the use of the Portal. Another observed behavior was preference for both print and electronic forms simultaneously by most respondents. The three main Internet usage purposes indicated by faculty are performing academic research, accessing email and shopping respectively. More qualitative research is recommended to better understanding of some of the results.

title: Technical-ministers and politician-ministers during PSDB and PT presidencies

description: ABSTRACT Studies on ministerial recruitment have identified the presence of professional politicians as well as technicians within the Brazilian ministerial cabinet. However, career analyses are restricted to technicians, while studies on political ministers have largely focused on party recruitment criteria. The objective of this article is twofold: to empirically demonstrate the differences and similarities between the careers of political and non-political ministers “technicians” during PSDB and PT presidential administrations between 1995 and 2014; and to explore the main aspects regarding the professionalization of politician ministers based on their experiences in elective and high-ranking positions in county and municipal administrations. The results indicate that both politicians and non-politicians have extensive professional experience, including administrative experience, although non-politicians have greater affinity with the ministerial area for which they were appointed as do ministers affiliated with the president’s party when compared to politicians of the allied base. Notwithstanding these nuances, no significant differences were found between PSDB and PT administrations regarding the expertise of their ministers.

title: Association between systemic activity ındex and dry eye severity in patients with primary Sjögren syndrome

description: ABSTRACT Purpose: The aim of the present study was to compare the severity of ocular and systemic findings among patients with primary Sjögren syndrome. Methods: The study followed a prospective controlled design and comprised two groups; the test group included 58 eyes of 58 patients newly diagnosed with primary Sjögren syndrome with poor dry eye test findings and the control group included 45 right eyes of 45 healthy age- and sex-matched individuals. The ocular surface disease index score, tear osmolarity, Schirmer I test without anesthesia, fluorescein tear breakup time, and cornea-conjunctiva staining with lissamine green (van Bijsterveld scoring) were used to examine tear function in the patients via a complete ophthalmological examination. The results were graded and classified on the basis of a Dry Eye WorkShop report and results of the corneal and conjunctival staining test, Schirmer’s test, and fluorescein tear breakup time test. Discomfort, severity and frequency of symptoms, visual symptoms, conjunctival injection, eyelid-meibomian gland findings, and corneal-tear signs were interpreted. Disease activity was scored per the EULAR Sjögren’s syndrome disease activity index (ESSDAI) via systemic examination and laboratory evaluations, and the EULAR Sjögren’s syndrome patient-reported index (ESSPRI) assessed via a survey of patient responses. Results: Mean patient age was 48.15 ± 16.34 years in the primary Sjögren syndrome group and 44.06 ± 9.15 years in the control group. Mean fluorescein tear breakup time was 4.51 ± 2.89s in the primary Sjögren syndrome group and 10.20 ± 2.39 s in the control group. Mean Schirmer I test result was 3.51 ± 3.18 mm/5 min in the primary Sjögren syndrome group and 9.77±2.30 mm/5 min in the control group. Mean ocular surface disease index score was 18.56 ± 16.09 in the primary Sjögren syndrome group, and 19.92 ± 7.16 in the control group. Mean osmolarity was 306.48 ± 19.35 in the primary Sjögren syndrome group, and 292.54 ± 10.67 in the control group. Mean lissamine green staining score was 2.17 ± 2.76 in the primary Sjögren syndrome group, and 0.00 in the control group. Statistically significant differences were found berween the primary Sjögren syndrome group and control group in terms of fluorescein tear breakup time, Schirmer’s test, lissamine green staining, and osmolarity tests (p=0.036, p=0.041, p=0.001, and p=0.001 respectively). The Dry Eye WorkShop score was 2.15 ± 0.98, the EULAR Sjögren’s syndrome disease activity index score was 11.18 ± 4.05, and the EULAR Sjögren’s syndrome patient-reported index score was 5.20±2.63. When potential associations of the Dry Eye Workshop Study scores and osmolarity scores with the Eular Sjögren’s syndrome disease activity index scores were evaluated, the results were found to be statistically significant (p=0.001, p=0.001 respectively). Conclusion: The results showed an association between dry eye severity and systemic activity index in primary Sjögren syndrome patients.

title: Failure behavior monitoring and evaluation of steel-confined reinforced concrete columns by acoustic emission under quasi-static loading

description: Abstract The mechanical behavior and failure evolution of steel-confined and unconfined reinforced concrete (RC) columns are investigated under quasi-static loading through acoustic emission (AE) signal. The excellent hysteresis response, lighter damage characteristics and delayed catastrophe of steel-confined RC columns are verified. Characteristic AE parameters were obtained during the test process, AE monitoring results indicated that the progressive deformation of the test specimens occurred in three stages representing different damage conditions. Extended AE features, including damage severity, modified cumulative signal strength ratio, sentry function, and b-value are calculated to evaluate the damage growth, failure mechanism, and estimate the critical points. The synthesis analysis of multi-indicators mutual verify, overcome the disadvantages of using single-indicator evaluation, and successfully be used to determine the complex damage properties, identify damage statuses, and provide critical warning information for steel-confined RC columns.

title: PERCUTANEOUS TREATMENT OF ANEURYSMAL BONE CYST WITH CALCITONIN AND METHYLPREDNISOLONE

description: ABSTRACT Objective: To introduce the intralesional calcitonin and methylprednisolone percutaneous injection method, which results in the promotion of primary aneurysmal bone cyst (ABC) healing. Methods: A retrospective cohort study involving 76 patients diagnosed with ABC was performed between 2005 and 2014. Patients treated with calcitonin and methylprednisolone injection and who underwent more than 2 years of follow-up were considered eligible for the study (n=47). The Enneking staging and Capanna classification systems were used during the initial evaluation. Treatment response was assessed by Rastogi radiographic grading based on the degree of healing. X2 and Wilcoxon signed-rank tests and odds ratio calculations were used in the statistical analysis with a 5% significance level. Results: The proximal tibia extremity was the most commonly affected site (17.0%). Thirty-three (70.3%) ABC cases were staged as B3 and 28 (59.7%) were classified as type II. The average number of injections performed was 2.8 per patient, with an average reduction of the initial lytic area of 83.7% (p-value=0.00001). Satisfactory results for 91.4% (n=43; p-value=0.00001) were obtained and 5 recurrences occurred. No side effects were observed. Conclusion: Intralesional calcitonin and methylprednisolone percutaneous injection is a minimally invasive, effective, and safe method for promoting primary ABC healing. Level of evidence IV, Type of study: case series.
