conclusions the most relevant finding was that hook pinning in pauwels type iii fracture may result in delayed :union: or non:union: due to significantly increased stress of a traction force at the fracture site that works to displace the fracture. however, in a pauwels type i fracture, increased compression stress contributes to stabilize it. surgeons are recommended not to treat pauwels type ...

An ionic current model of the retinal horizontal cell is constructed. The horizontal cell models are interconnected by gap junctions to form a horizontal cell layer. The light response properties of the L-type horizontal cell are analyzed using this model. We demonstrate the functional role of each ionic current and the role of the feedback loop between cones and horizontal cells. The present s...

We describe a stochastic birth-and-death model of evolution of horizontally transferred genes in microbial populations. The model is a generalization of the stochastic model described by Berg and Kurland and includes five parameters: the rate of mutational inactivation, selection coefficient, invasion rate (i.e., rate of arrival of a novel sequence from outside of the recipient population), wit...

The interface friction between geosynthetics has previously been extensively studied with reference to medium-high contact stresses. strength at low stress is a less investigated chapter whose importance, however, evident for the stability of geosynthetic landfill barriers during construction stage and covering systems. inclined plane most used laboratory test measuring normal stresses as 5 kPa...

The performance of plate anchors in sand, relative to clay, is not well understood, particularly for the more realistic case an inclined load. This paper investigates effect load inclination on horizontal sand through centrifuge tests and numerical finite-element simulations. were performed rectangular loose dense at shallow embedment depths with four different inclinations. experiments showed ...

the moist sample shrinks during drying and the non-uniformity shrinkage involves stresses in the body. the aim of the present work is simulating deformations and drying-induced stresses of carrot slice during a convective drying. the effect of shrinkage on the heat and mass transfer profiles were considered. non-constant physical and thermal properties were also incorporated in the model and th...

Pores in coal are not only the main space for coalbed methane (CBM) occurrence but also to be opened during CBM recovery. Therefore, analysis of impact hydraulic fracturing on pores, especially change adsorption pores before and after fracturing, is great significance evaluation effect Hydraulic experiments low-field nuclear magnetic resonance technology were used analyze changes T 2 curve, por...

Introduction: The Magellan mission to Venus [1] revealed the presence of at least 144 large volcanic edifices (i.e., those with flows extending > 100 km in diameter; Figure 1) [2-4]. Numerical models of coupled edifice growth and lithospheric flexure on Venus [5] revealed that horizontal compression in the upper lithosphere gets transmitted into the edifice, tending to halt magma ascent (and th...

The Afar and Ethiopian plateaus are in a dynamic uplift due to the mantle plume, therefore, considering plume effect is necessary for any geophysical investigation including estimation of lithospheric stress this area. Earth gravity models Gravity Field Steady-State Ocean Circulation Explorer (GOCE) structure can be applied estimate tensor inside lithosphere. To do so, boundary-value problem el...

Purpose is to improve analytical technique calculate strength of cylindrical rock samples taking into consideration standard horizontal stresses. Methods. Mathematical modeling sample breakage under the truncated-wedge destruction was performed stresses using four experimental characteristics (i.e. k being shear strength; f? and ? contact internal friction coefficients; ? elasticity modulus) as...
