Optimized communication plan and its impact on the contingency plan previously put in place for timely crisis response in the air sector

Analyze the crises spread in the Organization, taking into account their effects, response time (partial and total) and entities involved. In theory, the goal is to understand how the crisis response should be and how the system responds to the same type of crisis. There is a gap in the communication plan for crisis response in place. The deepening and exploration of typologies of organizational crises in the air sector, will to optimize the response times that can satisfy or mitigate the worsening of the situations, setting off a new challenge. It is through the methodology of gathering information, readings and research of the subject literature that this will be analyzed based in success cases, typologies of crisis and also models of response time exist. The study will shine a light on the different crisis typologies as well as their propagation at the Lisbon airport. Leading to the creation of a model or models for a quick and effective response to it. Thus minimizing the response time and eventual recourse due to the analysis of success stories in similar infrastructures. The objective of this study is to study is the production of a model or several. Therefor optimizing the response time in crisis situations as a result of studies and research on typologies of crisis and their effects in time and in the entities involved.info:eu-repo/semantics/publishedVersio

Nanoindentation of functionally graded hybrid polymer/metal thin films

Hybrid functionally graded coatings (2D-FGC) were deposited by magnetron co-sputtering from poly(tetrafluoroethylene) (PTFE) and AISI 316L stainless steel (316L) targets. The carbon and fluorine content varied from 7.3 to 23.7 at.% and from 0 to 57 at.%, respectively. The surface modification was developed to change the surface of 316L vascular stents in order to improve the biocompatibility of the outmost layer of the metallic biomaterial. In-depth XPS analysis revealed the presence of a graded chemical composition accompanied by the variation of the film structure. These results were complemented by those of transmission electron microscopy (TEM) analysis that highlighted the nanocomposite nature of the coatings. The nanomechanical characterization of 2D-FGC was performed by nanoindentation at several loads on the thin films deposited onto two different steel substrates: 316L and AISI M2. The study allowed establishing 0.7 mN as the load that characterized the coatings without substrate influence. Both hardness and Young modulus decrease with the increase of fluorine content due to the evolution in chemical composition, chemical bonds and structure

Amyand's Hernia in a 6-Week-Old Infant: A Delayed Diagnosis

In Amyand's hernia, the hernia sac contains the appendix. This can be normal and accidentally found during herniotomy or inflamed and present as acute scrotum, although the latter is less frequent. We present a case of a male infant with scrotal abscess resulting from Amyand's hernia, with appendicitis and periappendicular abscess

The effect of flooding on the exchange of the volatile C₂-compounds ethanol, acetaldehyde and acetic acid between leaves of Amazonian floodplain tree species and the atmosphere

The effect of root inundation on the leaf emissions of ethanol, acetaldehyde and acetic acid in relation to assimilation and transpiration was investigated with 2–3 years old tree seedlings of four Amazonian floodplain species by applying dynamic cuvette systems under greenhouse conditions. Emissions were monitored over a period of several days of inundation using a combination of Proton Transfer Reaction Mass Spectrometry (PTR-MS) and conventional techniques (HPLC, ion chromatography). Under non-flooded conditions, none of the species exhibited measurable emissions of any of the compounds, but rather low deposition of acetaldehyde and acetic acid was observed instead. Tree species specific variations in deposition velocities were largely due to variations in stomatal conductance. Flooding of the roots resulted in leaf emissions of ethanol and acetaldehyde by all species, while emissions of acetic acid were only observed from the species exhibiting the highest ethanol and acetaldehyde emission rates. All three compounds showed a similar diurnal emission profile, each displaying an emission burst in the morning, followed by a decline in the evening. This concurrent behavior supports the conclusion, that all three compounds emitted by the leaves are derived from ethanol produced in the roots by alcoholic fermentation, transported to the leaves with the transpiration stream and finally partly converted to acetaldehyde and acetic acid by enzymatic processes. Co-emissions and peaking in the early morning suggest that root ethanol, after transportation with the transpiration stream to the leaves and enzymatic oxidation to acetaldehyde and acetate, is the metabolic precursor for all compounds emitted, though we can not totally exclude other production pathways. Emission rates substantially varied among tree species, with maxima differing by up to two orders of magnitude (25–1700 nmol m−2 min−1 for ethanol and 5–500 nmol m−2 min−1 for acetaldehyde). Acetic acid emissions reached 12 nmol m−2 min−1. The observed differences in emission rates between the tree species are discussed with respect to their root adaptive strategies to tolerate long term flooding, providing an indirect line of evidence that the root ethanol production is a major factor determining the foliar emissions. Species which develop morphological root structures allowing for enhanced root aeration produced less ethanol and showed much lower emissions compared to species which lack gas transporting systems, and respond to flooding with substantially enhanced fermentation rates and a non-trivial loss of carbon to the atmosphere. The pronounced differences in the relative emissions of ethanol to acetaldehyde and acetic acid between the tree species indicate that not only the ethanol production in the roots but also the metabolic conversion in the leaf is an important factor determining the release of these compounds to the atmosphere

Thermal comfort for pregnant sows housed in individual and group stalls

Este experimento foi realizado no período compreendido entre 04/01 e 11/03/2005, em uma propriedade de produção industrial de suínos, localizada no município de Elias Fausto, estado de São Paulo. O objetivo da pesquisa consistiu na avaliação de diferentes sistemas de alojamento para matrizes gestantes, verificando-se as influências dos elementos meteorológicos e os aspectos relacionados à qualidade química do ar e seus reflexos no conforto animal na fase de gestação, determinando-se as condições favoráveis ao melhor desempenho animal, com base nas respostas ao ambiente de criação. O estudo foi desenvolvido no setor de gestação, com 24 matrizes primíparas, 12 fêmeas alojadas em baias individuais (T1) e 12 animais em baias coletivas (T2). O trabalho foi dividido em duas etapas: análise bioclimática e análise da qualidade química do ar. O delineamento experimental foi em blocos casualizados, com dois tratamentos e 67 blocos, e as médias comparadas pelo teste de Tukey. As variáveis meteorológicas (T, °C e h, kJ kg-1) apontam o sistema de alojamento em baias coletivas como aquele que permitiu melhor condicionamento térmico natural às matrizes em gestação apresentando valores da ordem de 25,03 °C e 62,02 kJ kg-1. As concentrações dos teores de gases não superaram as concentrações consideradas críticas para as matrizes.The experiment was carried out from January 4 to March 11, 2005 in a farm specialized in industrial production of pork, located in Elias Fausto, São Paulo State. This study evaluated different housing systems for pregnant sows looking at meteorological element influences and aspects of air chemical quality on the animal thermal comfort. The optimal conditions for animal performance improvement were determined by analyzing behavioral data taken in the breeding environment. In the gestation facility 24 gilts were allocated: 12 in individual stalls (T1) and 12 in group housings (T2). This study was divided into two steps: bioclimatic analysis and analysis of the chemical quality of air. An experimental design using randomized blocks with two treatments and 67 blocks was used. Means were compared by the Tukey test. The variables (T, °C e h, kJ kg-1) indicated which confinement system in group-houses was the one that permitted the better natural thermal environment for pregnant gilts with values of 25.03 °C and 62.02 kJ kg-1. In relation to concentration of gases, mean levels did not exceed the concentrations considered limiting for sows

Electrochemical detection of in situ adriamycin oxidative damage to DNA

Adriamycin intercalation and in situ interaction with double helix DNA was investigated using a voltammetric DNA-biosensor. Oxidation and reduction of adriamycin molecules intercalated in double helix DNA were investigated in order to understand the in vivo mechanism of action with this anti-neoplasic drug. The results showed that the interaction of adriamycin with DNA is potential-dependent causing contact between DNA guanine and adenine bases and the electrode surface such that their oxidation is easily detected. A mechanism for adriamycin reduction and oxidation in situ when intercalated in double helix DNA immobilised onto the glassy carbon electrode surface is presented and the formation of the mutagenic 8-oxoguanine explained.http://www.sciencedirect.com/science/article/B6THP-44PVS7R-M/1/1474d369a4b1d556b84d548d2df2543

Reflection on Risk Factors, Ashtma and Tobacco Smoke Exposure

O impacto da asma brônquica nas últimas décadas, nomeadamente em idade pediátrica, associando prevalências significativas a uma tendência, gravidade e custos crescentes, tem levado a que se efectuem múltiplos estudos para esclarecer causas, avaliando riscos, permitindo a elaboração de programas de prevenção. Estudos epidemiológicos bem desenhados, aplicados a amostras populacionais significativas, permitem identificar determinantes independentes da asma, viabilizando a actuação. Se muito se tem avançado no conhecimento das bases fisiopatológicas da doença alérgica, é com alguma preocupação que sentimos que a comunidade médica, mesmo a especializada, não sente as evidências epidemiológicas como aplicáveis à sua população de asmáticos. “Precisamos de mais estudos”, é declaração comum. Com este trabalho, centrado em três rastreios efectuados com a coordenação dos autores, pretendemos demonstrar que existem factores preveníveis, moduláveis, que podem permitir reduzir a morbilidade da doença asmática. Entre estes, o tabagismo passivo assume uma relevância ímpar, por ser o principal factor de risco para a gravidade da asma pediátrica em Portugal

Natural polymorphisms of HIV type 2 pol sequences from drug-naive individuals

Until today, the susceptibility of human immunodeficiency virus type 2 (HIV-2) to protease and nucleosidic reverse-transcriptase inhibitors (PI and NRTI, respectively) has not been clearly documented. In this report we studied HIV-2 proviral sequences (n = 30) from drug-naive patients. Our results revealed that several amino acid positions in the protease and reverse transcriptase coding sequence harbored residues that have been associated with drug resistance in HIV-1-infected patients. In particular, the M46I substitution in the protease was detected in 90% of the sequences analyzed, which, together with the other substitutions identified, may indicate a reduced susceptibility of HIV-2-infected drug-naive patients to PI. Furthermore, interpretation of genotypic data with four available algorithms, developed for interpretation of HIV-1 sequence data, suggested nonoverlapping profiles of drug resistance

The effect of flooding on the exchange of the volatile C₂-compounds ethanol, acetaldehyde and acetic acid between leaves of Amazonian floodplain tree species and the atmosphere

International audienceThe effect of root inundation on the leaf emissions of ethanol, acetaldehyde and acetic acid was investigated with 2?3 years old tree seedlings of four Amazonian floodplain species by applying dynamic cuvette systems under greenhouse conditions.
