Abstract: This article’s objective is to better understand the elements of informal coordination in the management of high performance teams acting in complex and unpredictable scenarios. We present the results of an empirical study in a police special operations unit. We conducted a qualitative and quantitative research, respectively though oral history, in-depth interviews and survey. Our results show that the sense of a common mission, trust relationships and leadership quality are central elements to better explain informal coordination. We observed higher levels of trust between peers, as compared with trust in superiors and teams, as a fundamental constitutive element of the power of the bond found among members. Our analyses also indicate strong relationships between trust in superiors and affective and normative commitment, and the importance of loyalty and pride in membership.

Abstract: this study examined the spatial and temporal variations of six important parameters of the salt accumulation process in water samples collected along section urban of contas river. the na+, k+, ca2+ and mg2+ concentrations were determined by faas. the conductivity, total dissolved solids, na+ and ca2+ presented the largest seasonal and spatial variations in the urban area demonstrated that are appropriate indicators of urban contamination. the readily soluble salts in drainage urban, contribute for the degradation of the water of rivers located in semi-arid zones.

Abstract: the objective this work was to verify the relative contribution between yield components and yield of the common bean landraces cultivars. the experiment was carried out with twenty six genotypes of beans under field conditions in the 2008/2009 growing season using randomized block design with three repetitions, where evaluated the yields components and yield in the in the following santa catarina countries: anchieta, joa?aba and lages. the unvaried variance test was used and the cropping places were compared by tukey test and, scott-knott test to grouping genotypes. the correlations were done by path analysis. the genotypes evaluated performed differently according to the environment where the tests were done to all characters, with exception to the mass of 100 grains. the indirect selection by mass of 100 grains to yield component isn't a good alternative to genetic progress. but, the selection to pod number per plant, grain per pod and pod loci number can contribute to yield selection.

Abstract: wheat leaf rust caused by puccina triticina is an important disease affecting wheat (triticum aestivum) worldwide. disease symptoms are normally shown on the upper leaf surface, but they can be observed in the leaf sheaths. in this work, epidemic rate and lesion distribution were characterized for the development of a simulation model. diseased leaves were collected at regular intervals during the 2006 and 2007 seasons, in tamandaré do sul, rs. two commercial wheat fields were used for sampling. a digital image was obtained for each sampled leaf. software was used to assist counting and determining the exact location of leaf rust lesions. the quantification of the number of lesions was made on individual leaves. the data set representing the epidemic progress was adjusted to a logistic model with three parameters. a descriptive analysis indicated that the position of leaf rust lesions followed a random pattern at the beginning of the epidemic, shifting to an aggregate pattern as the epidemic advanced in time. the cubic log- polynomial model successfully predicted portions of leaf area more likely to bear lesions. further exploration of these techniques could help the statistical modeling of host-pathogen relationships. moreover, the model can be used to generate a useful diagrammatic scale with gradients of severity.
The attitudes of nurses from an intensive care unit in the face of errors: an approach in light of bioethics
Coli, Rita de Cássia Pires;Anjos, Marcio Fabri dos;Pereira, Luciane Lucio;
Revista Latino-Americana de Enfermagem , 2010, DOI: 10.1590/S0104-11692010000300005
Abstract: this study analyzed the attitudes of nurses concerning the occurrence of errors in nursing procedures carried out in an intensive care unit (icu) based on the bioethics framework. this descriptive study with qualitative approach was carried out with 14 nurses from a private hospital in the city of s?o paulo, brazil. results were analyzed according to bardin’s proposal of content analysis. the resulting themes were: acknowledging one’s fallibility; acknowledging and reporting errors; hiding errors. the nurses’ reports are based on considerations through the lens of bioethics: taking responsibility for an error implies acknowledging one’s own vulnerabilities; acknowledging an error with responsibility implies ethical conditions in the relationships among those involved; and errors are in the context of a particular environment. this study enables re-thinking nursing practice based on bioethics, resorting to the analysis of errors focusing on the relationships between those involved.
Trombose da veia de Galeno: relato de caso

Arquivos de Neuro-Psiquiatria , 2003,
Abstract: A trombose venosa cerebral (TVC) é doen a vascular com diferentes manifesta es clínicas e várias causas possíveis (locais, sistêmicas ou idiopáticas). A trombose da veia de Galeno (TVG) é causa rara de TVC e geralmente está associada a alguma malforma o vascular. Relatamos o caso de uma paciente de 16 anos que apresentou TVG sem malforma o vascular, porém associada a trombose de seio reto e infarto venoso talamico. Discutem-se também aspectos importantes do diagnóstico clínico, radiológico e laboratorial da TVC.

Abstract: The Soy Moratorium is a pledge agreed to by major soybean companies not to trade soybean produced in deforested areas after 24th July 2006 in the Brazilian Amazon biome. The present study aims to identify soybean planting in these areas using the MOD13Q1 product and TM/Landsat-5 images followed by aerial survey and field inspection. In the 2009/2010 crop year, 6.3 thousand ha of soybean (0.25% of the total deforestation) were identified in areas deforested during the moratorium period. The use of remote sensing satellite images reduced by almost 80% the need for aerial survey to identify soybean planting and allowed monitoring of all deforested areas greater than 25 ha. It is still premature to attribute the recent low deforestation rates in the Amazon biome to the Soy Moratorium, but the initiative has certainly exerted an inhibitory effect on the soybean frontier expansion in this biome.

Abstract: cerebral venous thrombosis (cvt) is a vascular disease with many clinical manifestations and possible etiologies (local, systemic or idiopathic). galen vein thrombosis (gvt) is a rare cause of cvt and usually it is associated with some vascular malformation. we report a case of a 16 years old female patient with gvt without vascular malformation, but associated with straight sinus thrombosis and venous thalamic infarct. relevant aspects of the clinical, radiological and laboratory diagnosis of cvt are also discussed.

Abstract: studies on sewage sludge (ss) have confirmed the possibilities of using this waste as fertilizer and/or soil conditioner in crop production areas. despite restrictions with regard to the levels of potentially toxic elements (pte) and pathogens, it is believed that properly treated ss with low pte levels, applied to soil at adequate rates, may improve the soil chemical and microbiological properties. this study consisted of a long-term field experiment conducted on a typic haplorthox (eutroferric red latosol) treated with ss for seven successive years for maize production, to evaluate changes in the soil chemical and microbiological properties. the treatments consisted of two ss rates (single and double dose of the crop n requirement) and a mineral fertilizer treatment. soil was sampled in the 0-0.20 m layer and analyzed for chemical properties (organic c, ph, p, k, ca, mg, cec, b, cu, fe, mn, zn, cd, ni, and pb) and microbiological properties (basal respiration, microbial biomass activity, microbial biomass c, metabolic quotient, microbial quotient, and protease and dehydrogenase enzyme activities). successive ss applications to soil increased the macro- and micronutrient availability, but the highest ss dose reduced the soil ph significantly, indicating a need for periodic corrections. the ss treatments also affected soil microbial activity and biomass negatively. there were no significant differences among treatments for maize grain yield. after seven annual applications of the recommended sludge rate, the heavy metal levels in the soil had not reached toxic levels.
