title: Nitrogen Transfer from Cover Crop Residues to Onion Grown under Minimum Tillage in Southern Brazil

description: ABSTRACT Nitrogen derived from cover crop residues may contribute to the nutrition of onion grown under minimum tillage (MT) and cultivated in rotation. The aim of this study was to evaluate the N transferred from different cover crop residues to the onion crop cultivated under MT in southern Brazil. In June 2014, oilseed radish, black oat, and oilseed radish + black oat residues labeled with 15N were deposited on the soil surface before transplanting onions. During the growth season and at harvest, young expanded onion leaves, complete plants, and samples from different soil layers were collected and analyzed for recovery of 15N-labeled residue. Oilseed radish decomposed faster than other residues and 4 % of residue N was recovered in leaves and bulbs at harvest, but in general, N in plant organs was derived from sources other than the cover crop residues. In addition, leaf N was in the proper range for all treatments and was adequately mobilized to the bases for bulbing. The N derived from decomposing residues contributed little to onion development and the use of these plants should be chosen based on their advantages for physical and biological soil quality.

title: Retrieving ascarid and taeniid eggs from the biological remains of a Neolithic dog from the late 9th millennium BC in Western Iran

description: BACKGROUND Paleoparasitology reveals the status of parasitic infections in humans and animals in ancient times based on parasitic particles found in biological remains from archaeological excavations. This line of research emerged in Iran in 2013. OBJECTIVE The identification of parasites from Neolithic times is an attractive subject that shows the oldest origins of parasitic infections in a given geographical region. From an archaeological point of view, this archaeological site is well-known for animal domestication and agriculture in ancient Iran. METHODS In this study, soil deposited on the surface and in the pores of a dog pelvic bone was carefully collected and rehydrated using trisodium phosphate solution. FINDINGS The results showed ascarid and taeniid eggs retrieved from the biological remains of a dog excavated at the East Chia Sabz archaeological site, which dates back to the Neolithic period (8100 BC). MAIN CONCLUSION The current findings clearly illustrate the natural circulation of nematode and cestode parasites among dogs at that time. These ancient helminth eggs can also be used to track the oldest parasitic infections in the Iranian plateau and contribute to the paleoparasitological documentation of the Fertile Crescent.

title: Ruthenium Complex Improves the Endothelial Function in Aortic Rings From Hypertensive Rats

description: Abstract Background: The endothelium is a monolayer of cells that extends on the vascular inner surface, responsible for the modulation of vascular tone. By means of the release of nitric oxide (NO), the endothelium has an important protective function against cardiovascular diseases. Objective: Verify if cis- [Ru(bpy)2(NO2)(NO)](PF6)2 (BPY) improves endothelial function and the sensibility of conductance (aorta) and resistance (coronary) to vascular relaxation induced by BPY. Methods: Normotensive (2K) and hypertensive (2K-1C) Wistar rats were used. For vascular reactivity study, thoracic aortas were isolated, rings with intact endothelium were incubated with: BPY(0.01 to10 µM) and concentration effect curves to acetylcholine were performed. In addition, cumulative concentration curves were performed to BPY (1.0 nM to 0.1 µM) in aortic and coronary rings, with intact and denuded endothelium. Results: In aorta from 2K-1C animals, the treatment with BPY 0.1µM increased the potency of acetylcholine-induced relaxation and it was able to revert the endothelial dysfunction. The presence of the endothelium did not modify the effect of BPY in inducing the relaxation in aortas from 2K and 2K-1C rats. In coronary, the endothelium potentiated the vasodilator effect of BPY in vessels from 2K and 2K-1C rats. Conclusion: Our results suggest that 0.1 µM of BPY is able to normalize the relaxation endothelium dependent in hypertensive rats, and the compound BPY induces relaxation in aortic from normotensive and hypertensive rats with the same potency. The endothelium potentiate the relaxation effect induced by BPY in coronary from normotensive and hypertensive rats, with lower effect on coronary from hypertensive rats.

title: Phytophagous mites on genetically modified maize with Bacillus thuringiensis genes

description: ABSTRACT: The study of non-target organisms such as mites, can provide information about the possible effects of transgenic maize cultivars on the arthropod community. This study aimed to evaluate the abundance of phytophagous mites in the area of Bt maize and evaluate the instantaneous population growth rate, and food preference of phytophagous mites on Bt maize. We registered the species occurrence and the number of adult mite individuals on four maize cultivars, one non-Bt 30F35, and three containing the proteins Cry1Ab (30F35 Yg), Cry1F (30F35 Hx) and Vip3a (Impacto Viptera). Cry proteins disrupt the midgut epithelium of insect pests. The food preference and instantaneous population growth rate (ri) were evaluated using the two-spotted spider mite Tetranychus urticae as model. The species Catarhinus tricholaenae and Aceria zeala were recorded. The Bt maize cultivars did not significantly affect the average number of C. tricholaenae and A. zeala mites compared to conventional cultivar. The population growth rates of T. urticae were similar for the different maize cultivars. T. urticae showed no preference between the leaf of Bt or conventional cultivars. Bt maize did not affect the abundance of species in phytophagous mite.

title: OntoSmart: an ontology-based information retrievel model

description: ABSTRACT Information retrieval system is a mediator element between a stock of information and its users. Its effectiveness depends on representation language of information items and requests of its users. This work presents an ontology-based information retrieval model which uses the formal structure of Vector Space Model. The vector that represent a document is created during the automatic indexing process, in which an ontology provide new terms in order to semantically enrich that representation. The search vector is created from a query expansion process, in which new terms are added in the search expression initially formulated by the user from inferences in the ontology. Using the proposed model, the OntoSmart system is being developed. Preliminary results show a significant improvement in the precision of search results.

title: Epidemiological profile of infectious keratitis

description: Abstract Objective: To evaluate the epidemiologic aspects of cornea ulcers in a referred ophthalmology private practice center. Methods: Retrospective study over electronic files of patients treated for corneal ulcers during a period of 7 years by the same physician (RJMF) at Centro de Olhos São Francisco, between june 2007 and june 2014. These patients were evaluated for risk factors such as: trauma causes, co-morbidities and contact lenses use. They were also evaluated by the microorganism found at the smears, treatment and patient's outcome. Patients that didn't return with the smears results or that didn´t have a complete follow-up were excluded from the study. Results: A total of 242 patients were fully treated during this period. 55 patients were excluded and 187 patients were included. 28.88% (54/187) were positive for gram negative bacteria, 27.81% (52/187) for filamentous fungi, 16.04% (29/187) for gram positive bacteria and only 1.07% for acanthamoeba. Twenty-four patients had negative cultures and 21 patients had combined infections (bacteria + fungi or other combination). Corneal collagen Cross-linking was effective on melting arrest in 16 of the 16 patients that we have submitted to this procedure during 2008 and 2009. Among all the patients that had corneal infection and were previously using contact lenses, 81% were infected by pseudomonas or pseudomonas associated with other gram negative bacteria. Filamentous fungi had a strong association with physical trauma. While use of saline solution for contact lenses cleaning had a strong association with gram negative bacteria and biological trauma, a strong association with combined infection. Conclusion: Gram negative bacteria (Pseudomonas) followed by filamentous fungi (Fusarium sp) were the most frequent etiologic agent found in our study. Cross-link was effective on corneal melting arrest. Pseudomonas aeruginosa was the most frequent isolated agent on hydrophilic contact lenses wearers.

title: Agency and discretion in police practice

description: ABSTRACT The interest in the individual-society relationship is characterized in social theory by the diversity concerning the role of agency in human action. In this article, we revisit the issue of agency in an applied perspective. We aim to examine agency in police practice through the analysis of the meta-agentive discourse emerged in a narrative whose theme was the disrespect of a police officer during a research interview. The analysis shows that: (i) despite the range of possible choices of actions circumscribed by the law and the situated contexts, a single route of action is usually applied to all situations that are evaluated as disrespect; (ii) there is a new model of police officer whose reflexive and critical character is aligned with a model of community-oriented police that the government has been trying to implement in public security policies in Rio de Janeiro.

title: Applied linguistics and language: towards radical indisciplinarity

description: ABSTRACT This article puts forward a view of Applied Linguistics and language committed to radical INdisciplinarity. To achieve this goal it congregates authors from different fields to reflect both upon historical processes of territorialization forged in the so-called Modernity and possibilities of transgression. The central argument is that border thinking involves many challenges, especially reexamining familiar norms and making them strange.
