background and aim: one of the key aspects of maternal care is observing the progress of labor. careful assessment of labor progress could provide mothers to be referred on time and could decrease the maternal and neonatal morbidity. this study aimed to compare diagnostic accuracy of purple line with transvers diagonal of michaelis sacral rhomboid to predict labor progress in nulliparous and mu...

A three-level domain decomposition is considered. Bodies in contact with each other are divided into subdomains, which in turn are the union of elements. Using an approach based purely on FETI (finite element tearing and interconnecting) algorithms with only Lagrange multipliers as unknowns, which has been developed by the engineering community, does not lead to a scalable algorithm with respec...

lateral and anterior displacements of mandible may cause malocclusion. the aim of this study was to determine the prevalence of these displacements in a population of 597 childrens age 12 in mashhad secondary schools. displacment of mandible was shown to be in 11.8 percent of the population (6.2 percent anterior and 5.6 percent lateral displacement).anterior displacement of mandible was diagnos...

Tapered columns are a type of column that is used for different purposes, including architectural purposes or structural needs to take into account the changes occur moments along with height column. For example, in highway bridges, tapered reduce number transmitted base and from there foundation. This research studied analysis short reinforced concrete variable cross-sections linear manner by ...

A new tracking design for laser systems with different arrangements of a quadrant photodetector, based on the principle of active disturbance rejection control is suggested. The detailed models of quadrant photodetector with standard add–subtract, difference-over-sum and diagonal-differenceover-sum algorithms for displacement signals are included in the control loop. Target moving, nonlinearity...

A diagonal Latin square is a Latin square whose main diagonal and back diagonal are both transversals. In this paper we give some constructions of pairwise orthogonal diagonal Latin squares. As an application of such constructions we obtain some new infinite classes of pairwise orthogonal diagonal Latin squares which are useful in the study of pairwise orthogonal diagonal Latin squares.

The state-space formalism [Elliott S. J., et al. (2007). J. Acoust. Soc. Am. 122, 2759-2771] allows one to discretize cochlear models in a straightforward matrix form and to modify the main physical properties of the cochlear model by changing the position and functional form of a few matrix elements. Feed-forward and feed-backward properties can be obtained by simply introducing off-diagonal t...

where θ = ∇ · u is the dilation and u is the displacement. The stress tensor σ ≡ σij , where (1.3) σij = θλδij + 2Gǫij + ν1θ,tδij + ν2ǫij,t + τij . In Eq. (1.1), c denotes the free cytosolic calcium concentration, D is its effective diffusion coefficient, f(c) is the function describing calcium transport into and out of the cytosol. In Eq. (1.3), ǫij are the components of the deformation tensor...

We obtain several results and examples concerning the general question “When must a space with a small diagonal have a Gδ-diagonal?”. In particular, we show (1) every compact metrizably fibered space with a small diagonal is metrizable; (2) there are consistent examples of regular Lindelöf (even hereditarily Lindelöf) spaces with a small diagonal but no Gδ-diagonal; (3) every first-countable he...
