In order to explore the optimal mining strategy of a fractured Enhanced Geothermal System (EGS) reservoir, we numerically investigated influence seven factors on heat production and conducted an optimization analysis multi-factor multi-level combination by orthogonal test based geological data at Qiabuqia geothermal field. Seven were considered, including five reservoir (fracture spacing, fract...

The existence of fixed point in orthogonal metric spaces has been initiated by Eshaghi and et. al [7]. In this paper, we prove existence and uniqueness theorem of fixed point for mappings on $varepsilon$-connected orthogonal metric space. As a consequence of this, we obtain the existence and uniqueness of fixed point for analytic function of one complex variable. The paper concludes with some i...

background: fracture, is discontinuity of anatomical bone relations. commonly, a maxillofacial fracture occurs after trauma but the etiology and pattern of this entity is different amongst countries. the aim of this study was to clarify the main causes of this entity in yazd to increase public and professional awareness to prevent more injuries and subsequent consequences. materials and methods...

The coastal region of southwest Saudi Arabia contains a thick sequence Late Oligocene basalts in the Jizan Group, which accumulated along continental rift that preceded opening Red Sea. These are targeted for disposal CO 2 emitted from industrial sources by subsurface carbon mineralization processes. potential Group depends on having adequate permeability fracture networks capable conducting in...

In this study, fracture orientations in carbonate reservoirs were determined using a multicomponent velocity analysis based on shear wave splitting. The is the estimated velocities of large seismic events with different polarizations. fractured zone dominant orientation, weak amplitude split events, including noise, result waves that are polarized toward symmetry and anisotropy axes propagate c...

Hilbert frames theory have been extended to frames in Hilbert $C^*$-modules. The paper introduces equivalent $*$-frames and presents ordinary duals of a constructed $*$-frame by an adjointable and invertible operator. Also, some necessary and sufficient conditions are studied such that $*$-frames and ordinary duals or operator duals of another $*$-frames are equivalent under these conditions. W...

conclusions stability of the clavicle is crucial for shoulder function and care should be taken not to miss or underestimate segmental bipolar fractures even with a low energy mechanism. authors believe that operative treatment should be taken into consideration for displaced fractures. introduction clavicle fractures are very common, accounting for approximately 4% of all adult fractures. segm...

introduction: orthogonal radial fields are those in which the central axes are perpendicular to each other. an example of these orthogonal fields is the set of craniospinal orthogonal fields that are used for radiotherapy of medulloblastoma. craniospinal radial fields consist of two parallel-opposed fields for brain exposure and one or two posterior spinal fields for spinal cord exposure. the m...

the main purpose of this article is to present an approximate solution for the two-dimensional nonlinear volterra integral equations using legendre orthogonal polynomials. first, the two-dimensional shifted legendre orthogonal polynomials are defined and the properties of these polynomials are presented. the operational matrix of integration and the product operational matrix are introduced. th...
