| ABSTRACT The power consumption and load capacity of agricultural machines have grown and the effects of pressure on the soil by tires have been still little investigated. In concern with sustainable development, the relationship machine-tire-soil must be in balance to give more consistency on the best use of tires for a given load. This study aimed to evaluate four tires of two constructive types, the bias belted tires and radial tires, both with respective rim diameters of 22.5 and 26.5 inches with variables measuring the footprint, elastic deformation, sinkage and resistance to penetration. A hydraulic press with an attachment shaft for tire mounting and a box of soil in which the tire has been imposed on a load of 53.00 kN using nominal pressures... |

| An extra large aperture scintillometer (XLAS) was used over several months across the Thau Lagoon (South of France) to retrieve one-wavelength scintillation and, thence, sensible heat flux. We present the experiment with the XLAS, an eddy-covariance station and meteorological stations measuring on or near the Thau Lagoon. Changes implemented to adapt the scintillometry processing schemes to the above water conditions are presented together with a full error budget, including sensitivity tests to the relevant parameters of the scintillometer processing scheme. The XLAS error budget amounts to 16% (systematic part) +/- 50% (random part). Sensible heat fluxes obtained using the XLAS under unstable atmospheric conditions are then compared to eddy-covariance... |

| The musculotendinous hood of the rotator cuff muscle complex is formed by four tendons which thicken and merge with the underlying glenohumeral capsule as they insert onto the respective regions of the humeral head. This insertional anatomy has been reported to exhibit several pathological patterns which serve as the basis for the operative repair of cuff tears. Since previous literature concentrated on macro-evaluations of tears specific to the supraspinatus tendon, the present study aimed to investigate the macro- morphological and morphometric parameters of all four rotator cuff tendons. Observation of the insertion site configurations and computation of the relative tendon morphometry were performed once the glenohumeral region in forty adult cadaveric... |
