چکیده
The Burgers vector b with components (1.1) is teated as a vector of a special space, it is called the Burgers space. The Burgers space is an imaginary space, it is assumed to be filled with the infinite ideal (non-distorted) crystalline grid. The tensor T̂ in (1.1) is a double space tensor : its upper index i is associated with some Cartesian coordinate system in the Burgers space, its lower index j is a traditional tensorial index associated with some coordinates y, y, y (no matter Cartesian or curvilinear) in the real space where the crystalline medium moves.

Comparison of Inferior Dental Nerve Block Injections in Child Patients Using 30-Gauge and 27-Gauge Short Needles
Introduction: The purpose of the present study was to record their pain sensation and to assess children`s reaction objectively and subjectively while receiving dental local anesthesia with 27- and 30-gauge needles. Methods: Forty children (24 boys and 16 girls) participated in this study. A random double-blinded crossover design was used so that each child served as his or her own control, rec...
متن کاملThe Effect of Gauge Measurement Capability and Dependency Measure of Process Variables on the MCp
It has been proved that process capability indices provide very efficient measures of the capability of processes from many different perspectives. These indices have been widely used in the manufacturing industry for measuring process reproduction capability according to manufacturing specifications. In the past few years, univariate capability indices have been introduced and used to characte...
متن کاملDesign and Simulation of Hot Cathode Ionization Vacuum Gauge with no X-Ray Limitations
In this paper, the MEMS type ionization gauge with no X-Ray limitations has been presented. Having the dimensions of 2.4 mm× 0.8mm × 1.4 mm, the designed gauge is 9000 times smaller than the conventional type and can operate in HV and UHV pressures up to 5×10-9 torr. Operating at the temperature of 750°C, the cathode of proposed gauge is implemented using nickel and works in a way in...
متن کاملDesign of Continuous Gauge Near-Bit Stabilizer, Using Optimized Hydraulics and Gauge Geometry in Mishan andAghajari Formation
The main task of drilling the formation by the bit is done via scraping, crushing and grinding. Discharging the fluid from the bit nozzles is done with high pressure which assists to break the rocks. Different parameters affect the bit selection and design for each drilling formation, but the most important one is drillability that depends on hardness of the formation. In this paper, the design...
متن کاملRain Gauge Station Network Design for Hormozgan Province in Iran
A rain gauge network should serve general as well as specific purposes such as water supply, hydropowergeneration, flood forecasting, irrigation, and flood control. The level of accuracy a network can achieve depends onthe number and locations of gauges in the network. In this study, a rain gauge network was designed for Hormozganprovince in the south of Iran. Monthly rainfall totals from 124 r...

In this work, we study the anisotropic inflationary models . In these models, an abelian gauge field non-minimally coupled to the inflaton field plays a role in the inflation dynamicIn a gauge field,the backgroundanswer is anisotropic, in the form of metric Bianchi. In order for the model to be consistent with the observations, the level of anisotropy should be small. The anisotropy power spe...
