today, market orientation plays a vital role in determining customers’ needs and success of organizations. market orientation has also influenced various organizations’ measures including innovation. therefore the aim of this research is to study the role of market orientation in innovation of bodybuilding clubs of golestan province. the population of this study comprised all 170 managers of bo...

One of the important process parameters affecting tensile strength and build time part is orientation. Therefore, in this study, FDM 3D-printed PLA parts were fabricated at different orientations to examine effects orientation on properties material. In regard, three print angles examined. According results, decreased when was aligned from flat upright direction 0° 90° printing angle. For orien...

A two part probabilistic model for polycrystalline microstructures is described. The model utilizes a Poisson–Voronoi tessellation for the grain geometry and a vector random field model for the crystallographic orientation. The grain geometry model is calibrated to experimental data through the intensity of the Poisson point field underlying the Poisson–Voronoi tessellation and the orientation ...

The present article focuses on changes in the mechanical properties of an all-oxide fiber-reinforced composite following long-term exposure (1000 h) at temperatures of 1000–1200°C in air. The composite of interest derives its damage tolerance from a highly porous matrix, precluding the need for an interphase at the fiber–matrix boundary. The key issue involves the stability of the porosity agai...

Dual three-dimensional networks of structural and transport elements were combined to model the effect of fracture on mass transport in quasi-brittle geomaterials. Element connectivity of the structural network, representing elasticity and fracture, was defined by the Delaunay tessellation of a random set of points. The connectivity of transport elements within the transport network was defined...

The authors report on a case of fracture of the distal humeral epiphysis sustained at birth. This is extremely rare. The main problem in treatment of this kind of fracture is correct and timely diagnosis. In almost all reported cases the fracture has been confused with elbow dislocation. The reason for this mistake is difficult roentgenological orientation owing to invisible ossification nuclei...

While empirical relationships between the mechanical properties of WC-Cocomposites and the carbide grain size and carbide volume fraction are qualitatively well-known, the influence of other microstructural features on the macroscopic properties hasbeen less clear. In this thesis, a comprehensive study of the effect of the interfacecharacter distribution (grain shape and misorie...

We have investigated the orientation of isolated fragments of Halobacterium halobium purple membrane (PM) adsorbed to poly-L-lysine-treated glass (PL-glass), by quanitative electron microscopy. Three lines of evidence support the conclusion that the cytoplasmic side of the membrane is preferentially absorbed. First, monolayer freeze-fracture reveals nonrandom orientation; more fracture faces (8...

Background Laying hens are often kept in barn or free-range systems where they must negotiate level changes in the house to access resources. However, collisions and resultant keel fractures are commonplace. Producers sometimes add ramps to make raised areas more accessible but designs vary and very little research has investigated bird preference or behaviour when using different ramp designs,...

The effect of grain shape and fracture on the interaction of high velocity granular slugs with rigid stationary targets is analysed for targets in normal and inclined orientations. The granular slugs comprise spherical, rodshaped or cubic grains and are constructed by connecting together spherical sub-particles with either rigid or beam connectors. The case when grain fracture is suppressed (ri...
