We evaluated the effect of emptying techniques a pontoon trap on mortality Atlantic salmon their spawning migration along Finnish coast northern Baltic Sea by tagging and releasing fish from commercial nets. Two methods currently used, traditional chute lifting bag, were compared. The bag has been developed primarily for minimising injuries during emptying. A custom-built Bayesian system model ...

Introduction: Facial fractures epidemiology varies with geographic region. Patients and methods: This study reports the frequency, demographic characteristics and aetiologies of facial fractures in a 5-year retrospective survey, in Burkina Faso. Results: In 349 patients, the fracture involved the mandible (44.5%), the zygomatic complex (38.9%), the maxilla (13.8%) or the naso-fronto-orbito-ethm...

Drilling into a rock massif is energetically extremely consumptive process. Hence the optimization of drilling regime with objective of energy consumption minimization, is very important. Proposed article discusses partial problem of this problem. During the drilling process it is useful to know the drilled rock type, whereas to particular drilled rock needs convenient drilling regime, which is...

protein serine/threonine kinase (ROCK), is one of the central regulatory molecules for cytoskeleton control and cell adhesion process. ROCK also involves in other cell functions such as apoptosis and tumor invasiveness. Rho kinase is thought to play an important role in a variety of cellar functions such as stress fiber formation, focal adhesion formation, cell aggregation, cell morphology, cyt...

In s ix 8to 1 1-year-old plantat ions of longleaf pine (Pinus palus tr i s Mill.) near Aiken, S.C., responses of understory vegetation, light, and soil watcr availability and litterfall were studied in relation to pine thinning (May 1994), herbicida1 treatment of nonpine woody vegetat ion (1995-1996), or the combined treatments (treatment responses described below are in absolute units) . Treat...

In this work, the effect of rock bolt angle on the shear behavior of Rock Bridges is investigated using the particle flow code in two dimensions (PFC2D) for three different Rock Bridge lengths. Firstly, the calibration of PF2D is performed to reproduce the gypsum sample. Then the numerical models with the dimensions of 100 mm * 100 mm are prepared. The Rock Bridge is created in the middle of th...

Discrete element model is used to simulate the flow of liquid-granule mixtures in an inclined channel containing a linear contraction. All the relevant particle/particle and particle/fluid interactions are included in the numerical model. The presence of the contraction induces different steady morphologies of the solid phase or the mixture depending on whether closed or open channels are used....

recently, particular attention has been paid to the stepped spillways due to the increasing effect of energy dissipation and the reduction of cavitations risks with the development of roller compacted concrete (rcc) technique. flow regimes on the spillways divide into three groups, namely skimming, jet and transition flow. compared to the numerical methods, the majority of performed studies in ...

No prior research has documented the different types of rock coatings in Yosemite Valley, despite the evident black streaks down Yosemite Falls, the light granitic rock exposed by recent rock falls contrasting with dark rock coatings, and the millions of visitors who have photographed the coated rocks of Yosemite. This paper identifies the types of rock coatings found on Half Dome, in Yosemite ...

Introduction: We have completed analysis of a new near-field rock count at the Mars Pathfinder landing site and determined that the previously published [1,2] rock count suggesting 16 % cumulative fractional area (CFA) covered by rocks is incorrect. The earlier value is not so much wrong (our new CFA is 20%), as right for the wrong reason: both the old and the new CFA’s are consistent with remo...
