Inflammatory mediators in naturally occurring rhinitis
No full textBackground: The mediators released during the allergic inflammatory reaction induce the clinical symptoms of the allergic disease and although there have been numerous studies investigating mediator release in allergen challenge models of allergic rhinitis very few have extended this approach to the study of natural disease.Objective: The aim of this investigation was therefore to measure mast cell and eosinophil mediator levels and indices of vascular permeability in naturally occurring rhinitis.Methods: Three groups of subjects were studied, normal non-rhinitics, seasonal allergic rhinitics in and out of the grass pollen season and perennial allergic rhinitics. Mediators were recovered using the technique of nasal lavage and the levels of tryptase, histamine, eosinophil cationic protein and albumin were determined. In addition, eosinophils were enumerated in nasal smears as an indices of underlying inflammation.Results: The levels of tryptase, eosinophil cationic protein and albumin were significantly higher in the lavage recovered from the symptomatic seasonal allergic rhinitics than when asymptomatic (P = 0.05, P = 0.003, P = 0.009, respectively). These levels of eosinophil cationic protein and albumin were also significantly higher than those of the normal non-rhinitics (P = 0.0008, P = 0.0.003, respectively). In the perennial allergic rhinitics the levels of tryptase, eosinophil cationic protein and albumin were higher than the normal non-rhinitics (P < 0.0001, P = 0.0003, P = 0.0001, respectively). The levels of tryptase and histamine were higher in the perennial allergic rhinitics than the seasonal allergic rhinitics (P = 0.0003, P = 0.006, respectively). These changes in mediator levels were accompanied by a significant influx of eosinophils into the nasal mucosa of both the symptomatic seasonal rhinitics, compared with asymptomatic (P = 0.04) and normal controls (P = 0.0006) and the perennial rhinitics compared to normal controls (P = 0.03).Conclusion: These results indicate that in both naturally occurring seasonal allergic rhinitis and perennial allergic rhinitis mast cell and eosinophil activation occurs and this is accompanied by an increase in vascular permeability. These measurements in lavage fluid provide a method of monitoring the mucosal cellular events in response to therapy.<br/
Helicopter flight around a ship's superstructure
No full textA computational fluid dynamics model of a hovering helicopter main rotor is developed to examine air flow in the presence of ship structures and side winds. An illustration of the problem is given. The rotor is modelled by modifying the governing Navier-Stokes equations in the region of the disc. The extra terms added to the governing equations apply a downward force to the fluid; these forces are independent of the flow around the rotor and are equal to the helicopter weight. The helicopter rotor model and the ship model are combined to yield one flow solution, which, due to the severe non-linearities of the problem, cannot be achieved by superposition. The resultant flow yields valuable data about the induced velocities at the rotor, which ultimately determine the control pitch and power required to maintain the hover in a given location. Indeed, the interactions between the rotor downwash and ship air flow are known to produce unexpected and adverse flight dynamic behaviour of the aircraft
CFD predictions of the influence of external airflow on helicopter operations when operating from ship flight decks
No full textA CFD model of a hovering helicopter main rotor is developed to examine airflow in the presence of ship structures and side winds. The rotor is modelled by modifying the governing Navier-Stokes equations in the region of the disc. The extra terms added to the governing equations apply a downforce to the fluid; these forces are independent of the flow around the rotor and equal to the helicopter weight. The boundaries of the computational domain are also modified in order to generate a physically correct solution. Flow solutions in both two and three dimensions are achieved using the commercial flow solver CFX 4.1. The flow solutions exhibit very good correlation with established momentum and power principles. In order to model helicopter operations from a ship's flight deck, typically a frigate, the rotor is modelled at several positions above a ship profile. Cross winds are applied to the computational domain. The thrust of the rotor is held constant and the resulting flow solutions are calculated. The power exerted at the rotor is obtained and compared to the ideal hover condition and computational flow solution

A Validated Framework for Measuring Interface Support for Interactive Information Seeking
No full textIn this paper we present the validation of an evaluation framework that models the support provided by search systems for different types of user and their expected types of seeking behavior. Factors determining the types of users include previous knowledge and goals. After an overview is presented, the framework is validated in two ways. First, the novel integration of the two existing information-seeking models used in the framework is validated by the correlation of multiple expert and novice analysis. Second, the framework is validated against the results produced by two separated user studies. Further, the refinements made by the first validation technique are shown to increase the accuracy of the framework through the second technique. The successful validation process has shown that the framework can identify both strong and weak areas of search interface design in only a few hours. The results produced can be used to either revise and strengthen designs or inform the structure of a user study

Pathology of rhinitis and bronchial asthma
No full textStudies of the pathology of rhinitis and asthma have identified similarities and differences between these two clinical conditions. With regard to symptoms, both the nose and the lower airways respond to neural stimulation by irritant substances, but a major difference is that engorgement of the capacitance vessels is the main cause of nasal obstruction in rhinitis, while muscle constriction is the major determinant of lower airway narrowing. There are also similarities and differences with respect to the role of inflammatory cells. In both conditions there is evidence of allergen-induced mast cell activation, with production of an array of mediators (some mast cell-derived and others originating from a variety of other cell types). Eosinophilia is also characteristic of both diseases--it is prominent even in mild forms of asthma, but is low in pollen-sensitive rhinitics outside of the season. T-cell activation and production of cytokines plays an important role in the development and maintenance of allergic disease, but the level of T-cell activation may differ between asthma and rhinitis. Further research into differences in cellular activity and response to treatment between these two diseases may help define factors which will determine whether atopic disease is expressed in the upper, lower, or both parts of the respiratory tract
Biologically generated habitat provision and diversity of rocky shore organisms at a hierarchy of spatial scales
No full textThe diversity and abundance of intertidal organisms found on moderately exposed shores were compared between biologically generated complex and less complex habitats at four different spatial scales. For macrobiota, comparisons were made between Fucus clumps and open areas (barnacle covered or bare rock) and then between barnacle covered rock and ‘bare’ rock. Microbiota were compared on barnacle plates and on the rock surface and at a finer resolution on the plates themselves and pits in the plates. Macrobiota were quantified at two levels of resolution by direct observation and under low power magnification. Microbiota were examined at two levels of resolution with a scanning electron microscope. For macrobiota the average number of species was significantly greater in complex habitats at both levels of resolution. The average number of individuals associated with the Fucus clumps was significantly lower than that on adjacent areas of barnacle covered and bare rock. However, the average number of individuals associated with the barnacle matrix was significantly greater than that on surrounding rock. The differences were entirely caused by a greater abundance of barnacles and species associated with the barnacle matrix on exposed rock outside the Fucus clumps. For microbiota there were large differences in species composition; cyanobacteria were predominant on the rock surface whilst diatoms dominated the barnacle plates. The diversity of this assemblage was low and no differences in species numbers were apparent between the two habitats. At a finer scale, abundance of individuals was much greater in the pits than on flat areas of the surrounding plates and there was a slightly elevated average number of species per sampling unit. This paper illustrates the importance of using a variety of resolutions to measure biodiversity and the importance of biological habitat provision in maintaining biodiversity
