results the results show that the individual and demographic factor (idf), organizational factor (of), h & s training factor (tf), workplace-human factor (whf), factor related to type of accident occurrence (taf), h & s risk management system factor (rmsf), and accident time factor (atf) were considered to be effective and significant independent latent factors in occupational injuries. conclus...

the joints between segmental rings can withstand a certain amount of bending moment as well as axial and shear forces. generally, in the structural analysis of tunnel segmental lining, the joints can be modeled as elastic hinges or rotational springs, and their rigidity should be demonstrated in terms of the rigidity of the joints or their rotational stiffness. therefore, the bending moment act...

the present study attempts to investigate lean production in iran khodro company in order to address the importance of renovation and implementation of strategic improvement cycle to achieve competitive advantage through improving product quality as well as correcting consumption pattern for energy in the country along with national strategies. due to its comprehensiveness, having clear framewo...

An algorithm is given for bringing the equations of monomial first integrals of arbitrary degree of the geodesic motion in a Riemannian space Vn into the form (FA) k = ∑ B ΓkABFB . The FA are the components of a Killing tensor Ki1...ir of arbitrary rank r and its symmetrized covariant derivatives. Explicit formulas are given for rank 1,2 and 3. Killing tensor equations in structural form allow ...

The structural equations for the Killing-Yano tensors of order two was investigated.The physical signification of the tensors Lαβγ and Mαβδγ was obtained using the dual transformation. The structural equations in the dual space was investigated. Permanent address:Institute for Space Sciences,P.O.BOX, MG-36, R 76900 MagureleBucharest, Romania e-mail:[email protected]
