Organisation des secours extrahospitaliers lors du sommet 2003 du G8: nouveau concept de poste médical mobile (PMM) [Prehospital medical care organization during the 2003 G8 summit: a new concept of Mobile Medical Squadrons (MMS)].

OBJECTIVE: The occurrence of the 2003 G8 summit in Evian and the threat of major civil riots or even terrorist attacks in the Swiss neighbourhood forced us to imagine a new system of rescue and medical care in case of numerous victims. Previous occurrences of the G8 in Europe or America have demonstrated the need of flexible and mobile structures, able to respond quickly to crowd movements, unlike the usual static structure of rescue systems designed for major accidents. METHODS: We developed a new concept of Mobile Medical Squadrons (MMS) consisting of several vehicles and medical care and rescue human resources. In our concept, each MMS consisted of 3 emergency doctors, 5 paramedics and 9 first-aid workers. They were designed to handle 15 patients, with a large autonomy in terms of rescue, medical care, evacuation and medical authority. The equipment included medical, resuscitation, simple decontamination, evacuation and communication materials. RESULTS: The MMS were dispatched four times during the G8 summit following civil riots. They took care of 12 injured patients. CONCLUSION: The concept of MMS as a reinforcement of the existing rescue and health care resources appears as a new flexible, a modular and useful concept for the medical management of collective prehospital emergency situations. Its use is suggested instead of the traditional static concept of rescue systems designed for major accidents.

Effect of laser on the remnant liver after the first 24 hours following 70% hepatectomy in rats

PURPOSE: To evaluate the mitochondrial function of the remnant liver (RL) in the early phase of liver regeneration in rats after 70% partial hepatectomy (PH). METHODS: Sixty male Wistar rats (200-250g) submitted to 70% PH were divided into five groups according to the time of euthanasia and application or not of laser light: C = Control, time zero; 2 minutes, 4, 6 and 24 hours after PH. The dose of laser radiation was 22.5 J/cm², wavelength of 660 nm (visible/red), in the remnant liver. We studied the respiration activated by ADP (state 3), basal mitochondrial respiration (state 4), respiratory control ratio (RCR) and mitochondrial membrane potential (MMP). RESULTS: The mitochondrial function of RL changed at 4 and 6 hours after PH, with a significant increase in state 3 and a concomitant increase in state 4 and with maintenance of RCR. MMP differed significantly between the groups biostimulated with laser radiation and the control group 4 hours after HP, with a substantial reduction in the non-laser groups. CONCLUSION: The laser light at the dose used in this study did not induce additional damage to the RL and seems to have delayed the hepatocellular metabolic overload of the remnant liver.

Influência da função distribuição de quebra na modelagem e simulação do circuito de moagem de Carajás - Parte 1 - ajuste de modelos

The perfect mixing model (PMM) is based on parameters derived from the equipment characteristics as well as ore breakage characteristics. Ore characteristics are represented through the appearance function. This function may be determined using JKMRC laboratorial methods or by standard functions. This work describes the model fitting process of the Carajas grinding circuit, using the JKSimMet simulator Two scenarios were used in model fitting exercises: 1) standard appearance function; and 2) appearance fund ion based on testing carried out on samples taken at circuit feed. From this assessment, the appearance function`s influence in the PMM,fit and it`s relation with the breakage rate were determined. The influence of the appearance function on the respective breakage rate distribution was assessed.

Influència dels tractaments mèdics i psicoterapèutics en la disminució del delicte en població addicta a drogues

En l'àmbit judicial es constata una relació entre drogoaddicció i delicte. Els addictes a drogues han iniciat amb freqüència algun programa de desintoxicació o han sol·licitat suport mèdic o psicològic. L'estudi es proposa avaluar l'associació entre la conducta il·legal i l'abús de substàncies tòxiques, així com interpretar l'eficàcia dels tractaments terapèutics en la disminució d’aquesta associació, i les repercussions de les teràpies tant sobre els pacients com sobre el seu entorn. És un estudi observacional prospectiu d’una mostra de 100 subjectes que tenen relació amb el consum de drogues d'abús, al Jutjat de Guàrdia de Barcelona i en subjectes interns del Centre Penitenciari de Joves de Barcelona. Els resultats de l’estudi diuen que el sexe masculí hi està representat en un 94%, la mitjana d’edat és de 25,5 anys, amb baix nivell d’estudis i sense professió qualificada. Gairebé la meitat de la mostra són estrangers i solters. Els pacients estudiats són politoxicòmans amb un consum majoritari de cocaïna (92%), cannabis (87%), alcohol (71%) i el 54% d’heroïna. Destaca l’alta freqüència dels UDVP i de la positivitat als tres virus (VIH, VHC, VHB), tot i que es demostra el descens de l’ús de la via parenteral. El 73% dels subjectes comenten delictes contra la propietat. El 93% de la mostra han estat en tractament, però en períodes curts (70%). El 72,7% que estan en PMM consumeixen habitualment cocaïna. Els pacients tractats amb psicofàrmacs són detinguts menys vegades que la resta de pacients. Pocs pacients han fet tractaments combinats amb psicoteràpia o lliure de drogues. Entre la població de detinguts, els tractaments rebuts han resultat beneficiosos pel que fa a autoestima, autoagressivitat, heteroagressivitat, conflictivitat penal i violència en els fets delictius, però aquestes variables quasi no es modifiquen en el cas dels joves. Els tractaments produeixen un benefici als pacients toxicòmans i disminueixen la conflictivitat penal. Els tractaments s’han d’iniciar en els primers estadis del consum, així com potenciar l’adhesió i el seguiment. Els centres penitenciaris de justícia juvenil, les comissaries i els jutjats de guàrdia són els llocs idonis per a l’abordatge del tractament del drogodependent.

Effect of blood components, abdominal distension, and ecdysone therapy on the ultrastructural organization of posterior midgut epithelial cells and perimicrovillar membranes in Rhodnius prolixus

The effects of blood components, nerve-cord severance, and ecdysone therapy on the posterior midgut epithelial cells of 5th-instar Rhodnius prolixus nymphs 10 days after feeding were analyzed by transmission electron microscopy. Cutting the nerve-cord of the blood-fed insects partially reduced the development of microvilli and perimicrovillar membranes (PMM), and produced large vacuoles and small electrondense granules; insects fed on Ringer's saline diet exhibited well developed microvilli and low PMM production; swolled rough endoplasmatic reticulum and electrondense granules; Ringer's saline meal with ecdysone led to PMM development, glycogen particles, and several mitochondria in the cytoplasm; epithelial cells of the insects fed on Ringer's saline meal whose nerve-cord was severed showed heterogeneously distributed microvilli with reduced PMM production and a great quantity of mitochondria and glycogen in the cytoplasm; well developed microvilli and PMM were observed in nerve-cord severed insects fed on Ringer's saline meal with ecdysone; Ringer's saline diet containing hemoglobin recovered the release of PMM; and insects fed on human plasma showed slightly reduced PMM production, although the addition of ecdysone in the plasma led to a normal midgut ultrastructural organization. We suggest that the full development of microvilli and PMM in the epithelial cells depends on the abdominal distension in addition to ingestion of hemoglobin, and the release of ecdysone.

Apoyo social a drogodependientes en programa de mantenimiento con metadona en una prisión

Goal: To learn more about the social support available to patients participating in a prison methadone maintenance program (PMM). Methodology: Descriptive, with controls. Setting: A penitentiary in Albolote (Granada) Population Sample: The total prison population was 1,579; 364 patients were included in the PMM; 35 were female and 329 were male. 60 patients, 7 women and 53 men, were used as cases. 30 non-drug dependent prisoners, 3 women and 27 men, were the control group. They had no antecedents of problems with drug addiction. Interventions: Interviews with cases and controls to learn about their addictive antecedents, family structure, socio-economic level, and a hetero-applied MOS questionnaire was completed. Percentages of each social support variable were obtained and compared using the chi-squared technique. Results: The overall support received is low in 38 cases (74.5%) and in 9 controls (30%): p = 0.0001. OR 0.1466, confidence interval at 95% (0.0538-0.3989). Support received is normal in 13 cases (25%) and 21 controls (70%): p = 0.0007. OR 0.69, confidence interval at 95% (0.44-0.93). All of the variables were statistically significant for non-drug addicts, except for emotional support, which was the same for both groups. Conclusion: The perception of inmates participating in the methadone maintenance program was that they received less social support than the non-drug dependent inmates.

Macrofauna edáfica em estádios sucessionais de Floresta Estacional Semidecidual e pastagem mista em Pinheiral (RJ): Rio de Janeiro State

Entre os diferentes tipos de organismos da macrofauna do solo, distribuídos em diversos tipos de habitats, com variados hábitos alimentares e ciclos de vida, alguns são capazes de responder rapidamente às alterações ambientais e, por isso, considerados bons indicadores do funcionamento dos ecossistemas. O presente trabalho teve como objetivo avaliar o efeito dos seguintes estádios sucessionais de Floresta Estacional Semidecidual Submontana do domínio ecológico da Mata Atlântica: floresta secundária estádio inicial (FSEI), floresta secundária estádio médio (FSEM), floresta secundária estádio avançado (FSEA) e uma área de pasto misto manejado (PMM) sobre a densidade, diversidade e composição da comunidade da macrofauna edáfica em duas épocas do ano, no município de Pinheiral (RJ). Para amostragem da macrofauna, foram retiradas oito amostras da serapilheira e da camada superficial (0-10 cm) do solo pelo método recomendado pelo programa Tropical Soil Biology and Fertility (TSBF), com adaptações. Predominaram Isoptera, Formicidae e Oligochaeta em FSEI, FSEM e FSEA e Formicidae e Oligochaeta em PMM. Não houve diferença significativa na densidade da macrofauna edáfica entre as áreas. Os maiores valores dos estimadores de diversidade utilizados (equabilidade de Pielou, riqueza total e média) foram encontrados em FSEA. Os valores de riqueza total mostraram aumento gradual de acordo com o estádio de sucessão, desde PMM até FSEI. Constatou-se maior número de indivíduos no solo do que na serapilheira em todas as áreas de floresta, nas duas épocas. Pela análise de componentes principais (ACP) realizada para os períodos seco e chuvoso, foi possível identificar maiores diferenças na composição das comunidades entre os estádios sucessionais para o período chuvoso. Nesta época, os estádios FSEM e FSEA estiveram associados a uma maior diversidade de invertebrados saprófagos e predadores do que PMM e FSEI, demonstrando influência do processo sucessional sobre a comunidade da macrofauna do solo.

Impacto del Sistema Integrado de Transporte Público de Bogotá en la Productividad de la Empresa Transportes Bermúdez S.A.

En el Plan Maestro de Movilidad se definió y acordó la estructura que tendrá el Sistema Integrado de Transporte Público que empezó a operar en Bogotá a partir del 30 de Junio de 2012. Las implicaciones de este nuevo sistema afectan tanto a los bogotanos, como a las 66 empresas que estaban habilitadas como operadoras del transporte público colectivo y a los transportadores, entre muchos otros factores involucrados. Para la puesta en marcha del SITP, Bogotá se dividió en 13 zonas, las cuales van a estar cubiertas por 432 rutas y tan solo 13 empresas que quedarán como las operadoras del sistema. La implementación del SITP ha sido criticado fuerte y negativamente por parte de los bogotanos, las empresas operadoras, los transportadores y entidades gubernamentales. Esto, debido a varios factores, como las condiciones de la malla vial, el proceso de chatarrización al que entrarán más de 6000 vehículos en el primer año, las exigencias medioambientales con las que deben cumplir los vehículos antiguos que quedarán circulando, los problemas con el nuevo sistema de recaudo, pero sobre todo por la falta de información que se ha dado a la sociedad sobre este cambio, que aunque paulatino, afectará de manera crucial la vida de los Bogotanos.

Introduction of 4-chloro-alpha-cyanocinnamic acid liquid matrices for high sensitivity UV-MALDI MS

Matrix-assisted laser desorption/ionization (MALDI) is a key ionization technique in mass spectrometry (MS) for the analysis of labile macromolecules. An important area of study and improvements in relation to MALDI and its application in high-sensitivity MS is that of matrix design and sample preparation. Recently, 4-chloro-alpha-cyanocinnamic acid (ClCCA) has been introduced as a new rationally designed matrix and reported to provide an improved analytical performance as demonstrated by an increase in sequence coverage of protein digests obtained by peptide mass mapping (PMM) (Jaskolla, T. W.; et al. Proc. Natl. Acad. Sci. U.S.A. 2008, 105, 12200-12205). This new matrix shows the potential to be a superior alternative to the commonly used and highly successful alpha-cyano-4-hydroxycinnamic acid (CHCA). We have taken this design one step further by developing and optimizing an ionic liquid matrix (ILM) and liquid support matrix (LSM) using ClCCA as the principle chromophore and MALDI matrix compound. These new liquid matrices possess greater sample homogeneity and a simpler morphology. The data obtained from our studies show improved sequence coverage for BSA digests compared to the traditional CHCA crystalline matrix and for the ClCCA-containing ILM a similar performance to the ClCCA crystalline matrix down to 1 fmol of BSA digest prepared in a single MALDI sample droplet with current sensitivity levels in the attomole range. The LSMs show a high tolerance to contamination such as ammonium bicarbonate, a commonly used buffering agent.

Conceptual Product Development in Small Corporations

The main objective of the thesis “Conceptual Product Development in Small Corporations” is by the use of a case study test the MFD™-method (Erixon G. , 1998) combined with PMM in a product development project. (Henceforth called MFD™/PMM-method). The MFD™/PMM-method used for documenting and controlling a product development project has since it was introduced been used in several industries and projects. The method has been proved to be a good way of working with the early stages of product development, however, there are almost only projects carried out on large industries which means that there are very few references to how the MFD™/PMM-method works in a small corporation. Therefore, was the case study in the thesis “Conceptual Product Development in Small Corporations” carried out in a small corporation to find out whether the MFD™/PMM-method also can be applied and used in such a corporation.The PMM was proposed in a paper presented at Delft University of Technology in Holland 1998 by the author and Gunnar Erixon. (See appended paper C: The chart of modular function deployment.) The title “The chart of modular function deployment” was later renamed as PMM, Product Management Map. (Sweden PreCAD AB, 2000). The PMM consists of a QFD-matrix linked to MIM (Module Indication Matrix) via a coupling matrix which makes it possible to make an unbroken chain from the customer domain to the designed product/modules. The PMM makes it easy to correct omissions made in creating new products and modules.In the thesis “Conceptual Product Development in Small Corporations” the universal MFD™/PMM-method has been adapted by the author to three models of product development; original-, evolutionary- and incremental development.The evolutionary adapted MFD™/PMM-method was tested as a case study at Atlings AB in the community Ockelbo. Atlings AB is a small corporation with a total number of 50 employees and an annual turnover of 9 million €. The product studied at the corporation was a steady rest for supporting long shafts in turning. The project team consisted of management director, a sales promoter, a production engineer, a design engineer and a workshop technician, the author as team leader and a colleague from Dalarna University as discussion partner. The project team has had six meetings.The project team managed to use MFD™ and to make a complete PMM of the studied product. There were no real problems occurring in the project work, on the contrary the team members worked very well in the group, having ideas how to improve the product. Instead, the challenge for a small company is how to work with the MFD™/PMM-method in the long run! If the MFD™/PMM-method is to be a useful tool for the company it needs to be used continuously and that requires financial and personnel resources. One way for the company to overcome the probable lack of recourses regarding capital and personnel is to establish a good cooperation with a regional university or a development centre.

Modelagem estocástica do índice de radiação ultravioleta na costa leste do nordeste do Brasil

The increase in ultraviolet radiation (UV) at surface, the high incidence of non-melanoma skin cancer (NMSC) in coast of Northeast of Brazil (NEB) and reduction of total ozone were the motivation for the present study. The overall objective was to identify and understand the variability of UV or Index Ultraviolet Radiation (UV Index) in the capitals of the east coast of the NEB and adjust stochastic models to time series of UV index aiming make predictions (interpolations) and forecasts / projections (extrapolations) followed by trend analysis. The methodology consisted of applying multivariate analysis (principal component analysis and cluster analysis), Predictive Mean Matching method for filling gaps in the data, autoregressive distributed lag (ADL) and Mann-Kendal. The modeling via the ADL consisted of parameter estimation, diagnostics, residuals analysis and evaluation of the quality of the predictions and forecasts via mean squared error and Pearson correlation coefficient. The research results indicated that the annual variability of UV in the capital of Rio Grande do Norte (Natal) has a feature in the months of September and October that consisting of a stabilization / reduction of UV index because of the greater annual concentration total ozone. The increased amount of aerosol during this period contributes in lesser intensity for this event. The increased amount of aerosol during this period contributes in lesser intensity for this event. The application of cluster analysis on the east coast of the NEB showed that this event also occurs in the capitals of Paraiba (João Pessoa) and Pernambuco (Recife). Extreme events of UV in NEB were analyzed from the city of Natal and were associated with absence of cloud cover and levels below the annual average of total ozone and did not occurring in the entire region because of the uneven spatial distribution of these variables. The ADL (4, 1) model, adjusted with data of the UV index and total ozone to period 2001-2012 made a the projection / extrapolation for the next 30 years (2013-2043) indicating in end of that period an increase to the UV index of one unit (approximately), case total ozone maintain the downward trend observed in study period

Reforma administrativa e gestão de políticas sociais em Mossoró: a falácia dos atores institucionais e sociais

The thesis entitled The administrative reform and social political management in Mossoró: the institutional and social staff's falacy. Comprehends a moment of apprehensiveness and analysis in the reestrcturing process of the city, whose process will show the formation of strategies and deployment of its relation with the social political affectiveness. It represents a single moment in the approach of such a kind of experience in the city. The analysis starts from the third mandate of the Mayor Rosalba Ciarlini Rosado, during the quadriennium 2001/2004, for being the time in which the public management got materialized, such as in the operational way of the social politics. For that, we delimitate this study in two distinct moments: the first one refers to the reform elaboration from the creation of the additional law nº 001/2000 GP/PMM: the second one refers to a practical reform from the social and institutional staff's speech. Within that scenary it was seen that the approaching, though partially, the State Reform and, consequently, the master plan of the state apparatus, which were made of theoretical matrices of such a project locally. However, that is a complex experience, that required the use of field and documental research for the proposed investigation and at the same time, prove the guiding hypothesis of it, what means a grouping of areas like: education, healthy, and social development in only one department City Citizenship Department that is able to materialize a new intitutional arrangement, according to the management principles in the public administration at the govern local level, configuring a reform and not just an institutional adequacy. In that context, it got necessary to apprehending the institutional and social actors' falacy as a way to prove or not the presented hypothesis. Among the first staff, we have the mayor's direct leaders and advisors' perception that express the politcal administrative aspects of the reform and, in the second, the perception of the political view of what has changed concerning the management of the social politics

Avaliação de pastagens tropicais em sistemas de produção de ovinos de corte no nordeste brasileiro

He aim of this study was to evaluate the structural characters, herbage accumulation, nutritive value and performance of sheep in different tropical pastures. The treatments were two cultivars and two of the genera Panicum Brachiaria pastures under intermittent stocking and variable stocking rate, in the rainy season. We evaluated the masses and the components of herbage pre grazing in two layers, and after grazing. Chemical analyzes were made of the stems and leaf blades pre grazing in two layers. We used 48 male sheep and whole for the assessment of individual weight gain and area, and anestrous females to adjust the stocking rate. In the cv. Massai showed the highest herbage mass, leaf blades and dead material, and the largest volume density and leaf blade: stem pre grazing. There was no difference among cultivars for the percentage of leaf blade (PLB) in both strata, but the higher the PLB was higher than the bottom. The highest percentage of dead material (PDM) was observed in cvs. Massai and Marandu in the two strata. In cvs. Massai and Piatã were observed lower levels of crude protein in stem and leaf. In stratum 0-25 cm lower nutritional value was observed in the stem in the leaf blades did not grant the nutritional value among the strata. Herbage mass, leaf blade, PLB and proportion of stem in the residue of the Massai pastures were higher than cv. Aruana. There was no difference for efficiencies in harvest leaf and stem between the cultivars. The cv. Massai got the higher accumulation of leaf per cycle per day. Animals kept in grass swards Aruana had the highest average daily gain. The higher stocking rates and earnings per area were observed in grass swards and Marandu Massai. The cultivars are suitable for sheep meat production in the rainy season

Effects of powder preparation and sintering procedure on microstructure and dielectric properties of PLZT ceramics

PLZT ceramics belong to one of the very important groups of functional materials that make a basis for the production of a large range of electronic devices. The microstructure and properties of ceramics depend on the powder preparation and thermal processing conditions. Various techniques have been used to obtain chemically homogeneous and fine starting powders. PLZT powders have been prepared by two different production routes: by a modified Pechini method, using a polymeric precursor method (PMM) and by a partial oxalate method. A two-step sintering process, including a hot pressing, was carried out at 1100 and 1200degreesC Distinct phases obtained during the sintering process have been investigated by SEM and EDS techniques and dielectric properties such as permittivity and dielectric loss were measured in a frequency range from 1 to 20 kHz.. A significant difference in microstructure and dielectric properties, depending on powder origin and sintering procedure, has been noticed.
