ABSTRACT: BACKGROUND: Phenotyping asthma according to airway inflammation allows identification of responders to targeted therapy. Induced sputum is technically demanding. We aimed to identify predictors of sputum inflammatory phenotypes according to easily available clinical characteristics. METHODS: This retrospective study was conducted in 508 asthmatics with successful sputum induction recruited from the University Asthma Clinic of Liege. Receiver-operating characteristic (ROC) curve and multiple logistic regression analysis were used to assess the relationship between sputum eosinophil or neutrophil count and a set of covariates. Equations predicting sputum eosinophils and neutrophils were then validated in an independent group of asthmatics. RESULTS: Eosinophilic (>=3%) and neutrophilic (>=76%) airway inflammation were observed in 46% and 18% of patients respectively. Predictors of sputum eosinophilia >=3% were high blood eosinophils, FENO and IgE level and low FEV1/FVC. The derived equation was validated with a Cohen's kappa coefficient of 0.59 (p < 0.0001). ROC curves showed a cut-off value of 220/mm3 (AUC = 0.79, p < 0.0001) or 3% (AUC = 0.81, p < 0.0001) for blood eosinophils to identify sputum eosinophilia >=3%. Independent predictors of sputum neutrophilia were advanced age and high FRC but not blood neutrophil count. CONCLUSION: Eosinophilic and paucigranulocytic asthma are the dominant inflammatory phenotypes. Blood eosinophils provide a practical alternative to predict sputum eosinophilia but sputum neutrophil count is poorly related to blood neutrophils. [less ▲]

In the present paper we report the distribution of the partial pressure of CO2 (pCO2) in surface waters along 13 transects in the English Channel, covering the four seasons. The spatial and temporal variability of pCO2 is controlled by a complex combination of primary production (from May to June), degradation of organic matter, temperature change, and freshwater inputs. Preliminary air-sea CO2 exchange computations suggest that the Channel is not a major sink of atmospheric CO2 and is probably neutral from the point of view of atmospheric coupling. This is mainly related to a relatively low export and/or burial of organic carbon and intense benthic calcification. [less ▲]

Data on the distribution of the partial pressure of CO2 (pCO2) were obtained during six cruises off the Galician coast, a region characterized by a seasonal upwelling. The values of pCO2 over the continental shelf are highly variable and range between 265 and 415 matm during the upwelling season and between 315 and 345 matm during the downwelling season. Both the continental shelf and off-shelf waters behave as significant net sinks of atmospheric CO2. The computation of the air-sea fluxes of CO2 over the continental shelf yields a net influx in the range of 2.3 (±0.6) to 4.7 (±1.0) mmol C m 2 d 1 during the upwelling season and 3.5 (±0.8) to 7.0 (±1.5) mmol C m 2 d 1 on an annual basis. During the upwelling season and on an annual basis, although the observed air-sea gradients of CO2 over the continental shelf are significantly stronger than those in off-shelf waters, the computed air-sea CO2 fluxes are not significantly different because of the important incertitude introduced in the calculations by the estimated error on wind speed measurements. The presence of upwelling filaments increases the influx of atmospheric CO2 in the off-shelf waters. During summer, important short-term variations of pCO2 are observed that are related to both upwelling and temperature variations. During winter the cooling of water causes important undersaturation of CO2 related to the effect of temperature on the dissolved inorganic carbon equilibrium constants. [less ▲]

Parametric numerical analyses have been performed with SAFIR for the temperature distribution in steel and composite beams and joints subjected to natural fires. A simple model has been derived to calculate the temperature development in the upper flange of the steel section supporting a concrete slab. This model takes into account, not only the heat transfer with the surounding hot gases, but also the heat transfer 1) by conduction with the lower part of the section through the web and 2) with the supported concrete slab.

The present article describes the existing methods and recommendations for the evaluation of temperature profiles in steel beams and joints covered by a concrete slab. Then, modifications and improvements to the existing methods are proposed in order to predict more accurately temperatures at the level of the top flange of the beam by accounting for heat fluxes between the steel elements and the concrete slab. The two methods presented in this article differ by the degree of simplicity, the field of applicability and the accuracy of the predicted results. Comparisons with numerical simulations performed in the finite element program SAFIR have been described for the validation of these new methods. It is assumed in these numerical models that the contact between the steel profile and the concrete slab is perfect. The “original” Lumped Capacity Method gives globally good predictions of temperature in steel and composite beams and joints but does not integrate heat fl uxes between the steel elements and the concrete slab. This leads to an over-estimation of temperature in the steel elements during the heating phase and to an under-estimation of temperature during the cooling phase. In order to take these fluxes into consideration in the evaluation of the top flange temperature, it is suggested in the first proposed method to integrate a part of the concrete slab into the heated surface or volume considered in the Lumped Capacitance Method. The Composite Section Method correctly predicts temperature at the level of the top flange under ISO fire or during the heating phase of parametrical fire curves but a delay is observed between these analytical results and those obtained from numerical simulations performed in SAFIR software. In a second method, called Heat Exchange Method, it is proposed to calculate separately the heat fluxes between, on one side, the top flange and, on the other side, the gases of the compartment, the rest of the steel section and the concrete slab. The temperatures given by this latter method are in very good agreement with those obtained from FE models. The use of this method is really less fastidious than the use of FE models, especially for joints, but is limited to a certain type of fire curves (parametrical fire curves defined in the Annex A of the EN 1991-1-2). Finally, a bilinear temperature profi le has been proposed to interpolate the analytically-calculated temperatures at the level of the top and bottom flanges on the total height. This procedure is simple and shows a good agreement with the numerical results in 2-D beam sections and 3-D joint zones during the heating and cooling phases of parametric fire curves. [less ▲]

Ten vertical samplings were carried out at five different stations. Eight species of Salps and six species of Doliolids were collected and their distribution examined. No Pyrosoma was caught. Catch below 100 m were not very numerous. Several species of Salps and Doliolids know from the northern Red Sea and its appendages were present in the catches: Brooksia rostrata, Ritteriella amboinensis, Iasis zonaria, Thalia cicar, Salpa cylindrica, Doliolina indicum, D. muelleri, D. krohni, Doliolum nationalis and D. denticulatum. Doliolina indicum, common in the northern part of the Sea and in the Gulf of Aquaba, was the most frequently caught species of Doliolid. Pegea confoederata, a new record, was locally very abundant. The standing stock of Thaliacea was very low, except at the N'Djebel Tair and Commision Plain stations. [less ▲]
