The experimental data indicated that, compared with the linear one, the hyperbranched HPU aqueous dispersions exhibited lower viscosity, and larger particle size.
The data show that at low temperature the intrinsic viscosities of all the HBPEs are almost not alterant Whereas, with the increasing of temperature, the intrinsic viscosity decreased sharply, resulting from the out-stretching of the branched chains of HBPE after absorbing heat. 3.2.
The data in Table 1 shows that the particle size for all the HPU aqueous dispersions is larger than that of the neat PU aqueous dispersion.
The data in Table 1 shows that all the HPU aqueous dispersions have the similar viscosity as neat PU, resulting from the highly branched sphere-like structures of hyperbranched HPUs, as there is little entanglement among the HPU molecular chains.
It can be presumed that the reduction of viscosity with increasing HBPE-3 content was due to the decreasing intermolecular entangling in the system.

Vibrational density of states for InP and CdTe as well as the static structure factor for liquid CdTe are in very good agreement with experimental data.
It needs to accurately reproduce a set of experimental data for the system of interest.
It should also be able to describe with some accuracy the structures and phases not included in the fitting data base.
Further transition to Immm and CsCl phases were predicted[23, 33, 34] but no experimental data confirm them.

The circular economy requires the "3R" principle, namely the reduction principle (Reduce), reuse principle (Reuse) and recycle principle (Recycle) as the guideline of economic activities.
The development overview of renewable resources industry in Chengdu.According to statistics data, in 2013, 1586.5 thousand tons of renewable resources were recycled within the Chengdu City recycling system(meanwhile the total amount of recycled renewable resources is 5037.01 thousand tons, see Table 1) , with total value of 3.76 billion Yuan, accounting for the Chengdu City renewable resources recycling industry’s total recovery of 31.49% and 31.99%, and compared with 2012 the numbers were decreased by 225.7 thousand tons and 811.36 million Yuan, a decline of 12.45% and 17.75%.

To estimate solar system performance it is primarily necessary to obtain the data on incoming solar radiation (SR) in the environment considered.
The geographic coordinates of the city of Nish and estimated total sums per month shown in the Table 1 have been taken as basic initial data.
The data obtained make it feasible to implement initial calculations and estimate whether it is rational to use solar systems to ensure heat and electric power supply in reference to a certain building.
With data estimated and analyzed it is evident that there are essential possibilities to ensure as lightning as heat and hot water supply using solar power if this pre-school facility is upgraded.
The Table 2 shows the data per year and per period from April, 1 to October 1 in reference to incoming SR power and electric power per 1m2 estimated for the surfaces with the angles of inclination equal to 30° being under consideration.

The reference distances, the group overlap integrals, the cubic field parameter Dq (in cm1) and the average covalency factor N, the molecular orbital coefficients N and  (and s), the spin-orbit coupling coefficients (in cm1) and the orbital reduction factors for NiX2 and CdX2:Ni2+ .
Substituting the above parameters into Eq. (1) and fitting the calculated results to the experimental data, the local angles  54.36 and 54.82 (6) can be obtained for Ni2+ in CdCl2 and CdBr2, respectively.
c The experimental data of zero-field splitting were not measured for NiX2 [18,19].
(1) The results (Cal. a) based on neglecting of the ligand contributions are worse than those including the above contributions, i.e., the calculated zero-field splitting and g factors are larger in magnitude than the experimental data.
(3) For CdX2:Ni2+ , one can find that the theoretical results (D  7.254, g//  2.287, g  2.238, and D  2.663, g//  2.206 and g  2.225 for X= Cl and Br, respectively) based on the host angles H do not show good agreement with the experimental data, particularly, the zero-field splittings are much larger than the experimental data.

Ethernet module allows viewing the network traffic and selecting only the data about specific traffic parameters.
One can also analyze data in real-time; however, it requires a reduction of the sampling frequency.
Data Transmission For data transmission, the special architecture of information system that allows exchanging the data between the components of the proposed system of the car simulator has been developed.
The Figure 2 shows the translation of an exemplar data packet sent to the host computer.
Since this loop has a higher priority than the loop used to record data on disk (Fig. 7), the data sent in this way will not be lost even if the computer is overloaded until the overflowing of the FIFO queue.
