The resulting reduction in stress was modeled numerically and the crystals were investigated by X-ray topography (XRT) and molten potassium hydroxide (KOH) etching.
The data set draws a line from the center of the crystal to the edge, at the same position where the respective wafers A1 and B1 are taken from.
Although 26 m is still a comparatively high amount of bow, the reduction in regard to wafer A1 is apparently enough to prevent the formation of BPD arrays.
The reduction of the temperature gradients has to be implemented carefully.
The numerical calculations predicted a reduction of shear stress by 54% in the wafers close to the crystal cap from a maximum value of 18.0 MPa in wafer A1 to 8.3 MPa in wafer B1.

The system framework is a blackboard system, which encapsulates information sharing through the common data structure termed a blackboard.
It stores the current state of the solution, problem data, intermediate parameters and final emergency relief outcomes.
Data inside Emergency Stage are employed by Forward chaining inference mechanism to derive the next emergency process.
User-friendly displays are used to interact with end users by prompting for values and showing the output data.
The system checks for consistency and accuracy of all input data and prompts a warning message if the data is not within the specified range.

A reduction of 150 mW/kg for a reduction of the A-parameter with 1° is possible.
The texture data were obtained by OIM measurements since the texture throughout the thickness of the samples is quite heterogeneous.
Shear bands have been observed after hot rolling from values as low as 15% of reduction and ending at relatively high temperatures of 800°C [2].
(b) ε-fiber intensity for: A) three different substrates after ICR (70% reduction) and DA at 1100°C for 30 min, B) FeSi with 2.4 m.-% Si, ICR reduction 40% and different DA treatments [7] Concentration profiles were measured by SEM-EDS, the resulting texture by means of EBSDSEM.
Fig. 4b compares the intensities of the ε fiber for different reduction and annealing.

Introduction From recently years’ college students’ physical health data, it can be known that their physique is in the drop tendency.
Fig.1 PDCA cycle 2.3 Principle Component Analysis The principle component analysis is a kind of statistic analysis that transforms many variables to a few principle components by applying the data dimensionality reduction technology.
It makes use of the linear combination method, and transforms many indexes into some typical comprehensive indexes based on losing fewer data information.

Additionally, reduction in heat conduction through window glazing further reduces the cooling costs.
Global focus is shifting towards considering energy saving and carbon emission reduction as a top priority while designing buildings.
Employing the data of the values obtained experimentally for LT , Ld and Lct , an interface was designed to determine the amount of optical fiber surface at the receiving node for the tracked-concentrated system.
Summary This work focused on the experimental data collection and further theoretical assessment of the concentration cum tracking based daylight enhancement system using POF light transport systems; as a complementary design for existing daylight integration systems and partial-to-total replacement of electric lighting.

Reduction in energy consumption, which means that low cost of heating and cooling needs, safer, clean and comfortable environment achieved.
In this work, the environmental affect of heat insulation used for reduction heat losses in building in addition to using of waste material, which is harmful for the environment.
Test machine used for the compression test Results and Discussion The recorded data for thermal conductivity, thermal resistant and overall heat transfer coefficient used to calculate the heat transfer rate at variable percentage of polystyrene added to the ordinary mixture for the general brick.
Variation of stress (P) with the polystyrene percentage Finally it must be mention that using these waste material such as waste polystyrene will be reflected on clean environment ,healthy and comfort conditions, energy saving and hence money , reduction in mould issue which made headache for all citizen because it enhance the thermal insulation performance.
The new building material is a high efficient thermally insulation material, healthy, clean, comfort conditions will be provide, which leads to low energy consumption and reducing the growth of mould and considerable reduction on the demand on electrical energy for cooling and heating purposes.

The obtained data show that the nanocrystalline hydroxyapatite with low contamination and suitable morphology can be produced in Polyamide6 vials similar to stainless steel vials, therefore it seems that using polymeric and polymeric based nanocomposite vials with high strength and wear resistance could lead to a new way for the mass production of nanocrystalline hydroxyapatite with high performance, low contamination and low cost.
According to data presented in Fig.2, and Table 2, by increasing the milling time, the crystallite size decreased but the lattice strain increased; but the rate of both of these variations (increase in the lattice strain and decrease in the crystallite size) decrease by increasing the milling time.
As can be seen, by increasing the milling time, reduction of particle size occurred but in this case the dominant phenomena were accretion and agglomeration.
It is evident in Fig.6 that by increasing the milling time, reduction of particle size occurred and the dominant phenomenon is agglomeration, until 60 hrs of milling.
With regard to the obtained data, a new method for the synthesis of nanocrystalline HA and preparation of spherical HA particles has been developed.

Functional results were very good; stability and ROM data obtained were within normal limits.
According this classification: Mason I injuries are treated conservatively; Mason II injuries conservatively or if displaced with open reduction and internal fixation (ORIF); and Mason III fractures with ORIF or radial head prosthesis [5, 6, 7].
Fracture type Characteristics type I - Nondisplaced or minimally displaced fracture of head or neck - No mechanical block to rotation - Displacement less than 2 mm or a marginal lip fracture type II - Displaced (usually > 2 mm) fracture of head or neck (angulated) - May have mechanical block to motion or be incongruous - Without severe comminution (technically possible to repair by open reduction and internal fixation) - More than a marginal lip fracture of the radial head type III - Severely comminuted fracture of the radial head or neck - Judged not reconstructible on basis of radiographic or intraoperative appearance - Usually requires excision for movement Management of a radial head fracture with elbow dislocation involves initially a reduction followed by repeat radiographs to analyze the success of the reduction.
Analysis of both radiographs, respectively the initial and after reduction will be carefully assessed for associated fractures or displacement that could suggest a complex injury or unstable elbow.
