Developments of advanced surgical adhesives have demonstrated a suitable alternative to sutures for wound closure, prevention of fluid leakage and reduction of infection in vivo[3].
All data was statistically evaluated using the two-way ANOVA analysis and Bonferroni post-test (p = <0.05).
In contrast, a reduction in cell number and alterations to cell morphology was observed of cells cultivated on chitosan films alone (B).

Viscosity reduction was associated with an increase in the severity value and was dependent on reaction temperature and time.
After raising from environment temperature to 60℃ then return, apparent viscosity decreases from 6200mPa.s to 4610mPa.s from 24℃ to 50℃, it consistent with rule which temperature increase then viscosity reduction, However, when temperature ranges in the scale of 50℃ to 60℃, apparent viscosity increases 48% from 4610mPa.s to 6830mPa.s.
Activated sludge rheology: A critical review on data collection and modelling [J].

Despite the visible advantages of high-nitrogen austenitic steels as the construction material, there is limited data related to their high-temperature deformation and the possibility of realization of superplastic flow in them [1,18].
The visualization of EBSD data was performed with the TSL OIM Analysis 6.2 software.
According to these data, initial coarse-grain specimens of V-alloyed HNS do not exhibit superplastic behaviour in high-temperature deformation regime.
Maximum total reduction of solution-treated billets achieved for considered V-alloyed HNS was about 50%, further rolling leads to a brittle fracture of the billets.
Microstructural analysis shows that room-temperature rolling of the billet to 50% reduction (CR50) doesn’t lead to grain refinement.

Experimental data indicate that power law relationships exist between da/dt and KI.
The raw data was used to determine the stress, strain, Mode I stress intensity factor, and crack growth rate.
The developed equation was employed in the reduction of experimental data to calculate KI in term of actual instantaneous load and crack length.
This method involved fitting an nth order polynomial to a set of crack length and time data.
However, the scatter of the crack growth rate is probably within the scatter of experimental data.

It has implemented the following facilities: · graphical user interface (GUI) used for introducing the geometrical parameters of the part to be modelled; · automatic checking of wrong data; · form showing to correct erroneous data; · automatic generation of optimized processing paths.
Checks the user data input are made using conditional and loops functions.
After the error detecting, windows warning and correcting data are displayed, shown in Fig.2, using predefined functions [6].
The first standard for exchanging data files was STL, conducted in 1984 by the 3D Systems company [7].
To exchange data it may be used other compliant standards: IGES files, STP, etc.

Aircrafts are provided with Flight Data Recorders (FDR) that are meant to keep records of flight parameters, data acquired from on-board instruments as well as systems and activities of the aircraft crew.
The indispensable provision for that is keeping records on pressure variation across the avionic hydraulic drive by the Flight Data Recorder (FDR).
Fig. 4 presents an example of a graph for pressure variations in the avionic hydraulic drive downloaded from the Flight Data Recorder of a military jet airplane.
Example of waveforms for variation of pressure in an avionic hydraulic drive stored in the Flight Data Recorder (FDR). 1) movements of the rudder (flight in a tight bend); 2) movements of the elevator (barrel roll) 3) repositioning of wings to the position of 60º; 4) repositioning of wings to the position of 30º; 5) activation of decelerons; 6) activation of flaps; 7) lowering of undercarriage; 8) retraction of undercarriage and flaps; 9) lowering of undercarriage and activation of flaps; 10) engine shutdown (the hydraulic pump drive) on the ground.

Magnetic field distribution data and current density predictions of the numerical model were compared with the literature and with the superconducting properties of explosively consolidated MgB2 samples measured experimentally.
The input data used in the numerical simulation regarding the physical dimensions of the SMES coil included 4 layers consisting of MgB2 cylindrical wires, with 24 turns on each layer having a total active cross sectional area of 44.72 mm2.
Critical current density data were obtained using the magnetisation data of the MgB2 samples and Bean’s critical state model.
Current density data which characterise the superconducting coil are shown in Fig. 5(a) with peak values reaching approximately 5.34 x108 A/m2.
(b) The superconducting behaviour of explosively compacted MgB2 samples have been determined experimentally by means of magnetisation measurements after applying Bean’s critical state model to the recorded SQUID magnetic moment data.

Based on computer and network communications, it can transfer, store, inquire, compare, display and share the medical data and remote video as well as audio information.
And other medical data processing can easily be added to this system, because its main form is relatively simple.
In the consultation process, the patient's medical image data in turn is the main consultation reference information.
During the process of reading data and updating, the user operation will not be interrupted by refreshing the whole page.
The data volume of medical images is generally large (there are several MB for a single image and there are several hundred MB for CT, and MRI images).

The pretreatment of animals with sulfotozifan 2-4 days prior to the irradiation has a positive effect on the animals’ clinical condition, normalizes their hematological parameters, increases the levels of T and B lymphocytes, inhibits peroxidation of lipids (POL), reduces the concentration of malondialdehyde (MDA), the final product of POL, in the erythrocyte hemolysate and blood plasma, and also promotes a reduction in the formation of radiotoxins.
Radiobiology has accumulated a large amount of experimental data indicating very strong biological effects of ionizing radiation on mammals, birds, and other living organisms.
Conclusion Based on the experimental data obtained, it has been established that the pre-treatment of animals with the synthesized agent sulfotozifan 4 days prior to the irradiation at an absolute lethal dose has a positive effect on the clinical condition of the animals, normalizes their hematological parameters, increases the number of T and B lymphocytes, reduces the content of malondialdehyde (MDA), POL final product, in the hemolysate of erythrocytes and blood plasma, as well as promotes a reduction in the formation of radiotoxins and provides 100% protection of the irradiated sheep.

This problem was successfully minimized to a total reduction of 25% in friction by implementing micro-texturing on the surfaces of piston ring.
Reduction in contact length and entrapment of wear debris were reported to be the main reason for the friction reduction while using textured surfaces at the contact interfaces [17].
It is possible to get enhanced surface quality with significant reduction in grinding forces by using MQL techniques with nano fluids.

Analysis of test results of surface textured cutting tools compared with conventional cutting tool would give comparison performance data of tool wear under identical machining conditions, surface finish evaluation and cutting force under identical machining conditions.
