Statistical analysis
All data were expressed as mean of ± SE and statistical analysis was made using the Statistical Package for Social Sciences (SPSS 11.0 software and Microsoft Excel 2010).
These data indicate a decrease in the exchange function of the lymphatic system.
These data indicate an increase in the ion content of cadmium in blood and tissues by 5-7 times from the initial values after chronic poisoning with sodium chloride.
The accumulation of cadmium ions in the lymph nodes leads to a reduction of transport and drainage of lymph tissue.
As it is evident from the data obtained after cadmium intoxication in rats the total protein content in plasma and lymph decreased and plasma portion of blood increased.

By using the proposed
relationship formulation, this validity will be presented by means of comparing the result of the
compression analysis with the experimental data.

From the orientation
mapping data, the boundaries in the deformation microstructures were analyzed.
Figure 1 shows the boundary misorientation maps obtained from the EBSD data of the IF steel ARB processed by various cycles (various strains).
Analyzed from the EBSD data through thickness of the sheet.
The EBSD orientation mapping like Fig.1 was carried out at six different thickness locations (center, t/t0 = 0.1, 0.2, 0.3, 0.4 and surface) for each cycle, and all the data were summarized in Fig.2.

Hydraulic System Tension Control Design
2.1 Trawl winch work flow diagram
Trawl winch work flow diagram as shown in Figure 2, the specific process of work: hydraulic motor drive winch machine rotation, cable drive the cable through the trident force gauge mechanical structure movement, trident force gauge installed on both sides of the tension sensor and displacement encoder, according to the tension on the cable release process changes, with the hydraulic motor speed change and the cable length change, after the tension sensor and displacement encoder will collect the hydraulic value of the winch hydraulic oil circuit port, after the electrical signal transmission of the oil pressure and tension converted into tension value signal transmission to the data collection box, the data will be transmitted to the main console to reflect the traction platform in the whole process of operation of the hydraulic motor speed, cable tension and length changes, PLC controller control hydraulic system
Trawl winch workflow diagram The tension value signal is transmitted via the data communication line to the programmable logic controller (PLC), which controls the differential pressure P at the motor port and the hydraulic motor speed by adjusting the electro-hydraulic proportional relief valve pressure to control the tension balance of the two winches within a certain permissible range[11].
The signal data from the encoder can be processed by means of a PLC high-speed calculation model, which can also be converted into the width of the web release in the software interface, as feedback information for the adjustment of the web tension. 2.2 Hydraulic system control diagram Trawl winch hydraulic schematic diagram as shown in Figure 3, which is a control system by controlling the flow size of various types of valves.
Too slow release speed will cause the reduction of operation efficiency and increase the work intensity, while too high release rate will cause the uneven traction force, resulting in the slackening of the left and right cables, which will cause the netting to overturn and the change of the netting, thus causing the failure of the release.
After the distance of net release exceeds the set length, the control system will switch the net release to manual dragging mode, at this time, the sensor will collect the oil pressure data of the left and right winches and adjust it to the traction tension, and use PLC for control, the difference between the set tension and the actual tension will be kept at a certain value, meanwhile, by adjusting the pressure difference between the left and right winches, the traction tension will be kept within a certain range of change.

If the crankshaft uses a "material reduction" approach to repair, due to spindle neck just processing 0.15-0.2mm, 80mm in diameter relative to their terms, can be neglected, so the life before manufacturing and after manufacturing are the same.
The data in able 5 is matched and the availability of valid data is n = 6 referred in Fig. 6 at the same time.
It could be drawn from above data that: (1) Test measured the non-quenched and tempered steel crankshaft fatigue limit moment for the M-1 = 3075 Nm, the standard deviation of Sn-1 = 134.2 Nm, from M-1 to meet the confidence level of 95%, less than 5% requirements. (2) Survival rate was 50% safety factor for n50% = 2.21, the survival rate of 99.9%, the safety factor for n99.9% = 1.90. (3) The batch crankshaft is safe and reliable, but the corner of processing needs further improvement.
Not only on the crankshaft design and optimization are of a certain sense, also shows that a "material reduction" or "additional material" (Arc Spray 3Cr13 repair crankshaft) when engine crankshaft is remanufactured.

The collision rule takes into account a reduction
of normal relative velocity of the two particles and a reduction of total tangential relative velocity.
Our data are reasonably well fitted by a Mittag−Leffler function (1).
The data shown have been obtained in a system composed of the grains of type (A), and have been averaged over 80 runs.
Our data show that the compaction dynamics strongly depends on the material properties of the grains.
We have proposed an analytical expression (5) for mobility which is consistent with simulation data.

Magnetic nanoparticles find uses in a wide range of applications, from data storage and sensors to medical imaging and cancer treatment.

European design concepts are discussed in view of available data and new developments in research, quality control, fabrication of specimen as well as testing techniques.
The data base for the logN-logΔσ-design lines in DIN EN 1999-1-3, covering LCF and HCF, was set up between 1960 and 2000 [2].
In addition, methods are introduced in case of necessary reductions due to corrosion or thickness effects.
Because of the welding also the reduction factors ro und ru for the strength values in the heat affected zone are presented.

Any
polynomial fitted to many data points could exhibit erratic behavior.
Cubic splines use three degree polynomial to connect the data points which often results in strikingly smooth curve fits [6].
The input data required is the crystallographic information of the magnetite crystal cell.
The maximum reduction of the particle size as compared to any CD is 84.54% at 0.75% of βCD.
The experimental data (Figure 9B) shows that the percentage of reflectance increases with the increasing of particle size at a constant wavelength.

After removing cesium cations, deactivating solutions can be used repeatedly, which leads to reduction of the total amount of liquid radioactive wastes on NPP [3, 4].
Above 210 °C, thermooxidative decomposition of the polymer occurs leading to reduction of radionuclide uptake efficiency [14].
Based on the obtained data, further studies were done with the sample RFR 3-1-210.
Based on the presented data, volume of 1M HNO3 solution can be reduced to 40 mL, thus, decreasing the amount of secondary wastes.
Obtained data shows that total breakthrough of Cs-137 in every sorption cycle does not exceed 5% that indicates high sorption efficiency.
