The comparison of obtained FE results with experimental data is presented and discussed for the pulling ribbed bars out of concrete blocks, the spalling of concrete cover at the automobile bridge and cracking of ballastless deck at the railway bridge.
The comparison of obtained numerical results with experimental data has been presented in Fig. 1.
The volume of corrosive material is about 2.0…2.5 times of the reduction of the bar cross-section; respectively, high pressure on the concrete is generated resulting in origination of cracks and their propagation through the concrete cover.
Crack propagation under progressive corrosion. a is the length of horizontal crack The obtained crack opening width d = 44mm on free surface for the reinforcement radius losses of D=40 mm demonstrate a satisfactory agreement with experimental data d ≈ 50mm [5].
However, practical realization of this approach demands considerable computational effort and additional experimental data for mechanical properties of concrete.

Results: There were no differences in patient age, fracture type, BMD, ASA, hospital stay and reduction quality.
Patient data also included operative time, postoperative complications, number of blood transfusions, level of pain (assessed by a visual analog scale, on the fifth postoperative day) and length of hospital stay.
In Group A, the reduction over time in the femoral neck-shaft angle was 6 ± 8, while in Group B, the reduction was 2 ± 1 (p < 0.002).
The reduction was well-maintained

Over the last 20 years of Rural Industry Reform, collective enterprises have caused a reduction.
of 1988-2011 in order to be unified, no data of Guizhou in 2002-2011 (1) In 1988-1996, there were 17 provinces whose rural industrial collective enterprises proportion declined, the provinces whose proportion is increasing and decreasing both showed a plaques centralized distribution.
Eastern proportion reduction of rural industrial collective enterprises is greater than the west, which shows that the east has become the leading area.
(Table 4) Fig.5 The reduction level in the proportion of number and gross output in 1997 (2) In 1997-2001, 29 provinces whose collective proportion dropped sharply presented a diffusional downgrade pattern.
In the early 1990s, because of market sluggishness, financial strain and reduction of tax, credit support and other preferential measures, stock cooperative enterprises reform was mainly applied to rural collective industrial enterprises, and its proportion began declining.

From the electrical characteristics data, it was known that the heat treatment could change the electrical characteristics of the Fe2TiO5 based-thermistor.
In order to carry out the reduction reaction as shown in equation 4, the thermal energy received by Fe2TiO5 material from the heat treatment process was used
The increase in the heat received can lead to an increase in the speed of the reduction reaction and increasing the amount of oxygen idle.
Furthermore, the heat treatment provided is a reduction process and the occurrence of oxygen vacuum flaws / the formation of Fe2+ ions in the ceramics become the source of free electron source for the conduction band.
For example NTC at the time reduction of 25 minutes at a temperature of 300 °C, has a room temperature resistance value (RRT) is 465 KΩ and the B value of 3459 K, respectively.

Data were collected in order to be compared with other methodologies, already used in the literature.
According to the Ministry of Mines and Energy (MME), this measure allows the reduction of imports of the diesel oil, adding value in the agribusiness of the biodiesel, in direct relation with other agro-industries (grains, oilseeds and meats) and inducing the improvement of agribusiness exports (processed products, instead of in natura) [9].
In this context, here, the proposal was to study the viability of biodiesel production, using alternative methodologies, such as the reuse of materials and reduction of the processing time.
In the latter case, in our laboratory, microwaves have been widely applied as an economically more feasible technological resource, due to their main advantage, that is the reduction of time and processing temperature.
The proposed methodology may contribute to the reduction of basic sanitation costs.

"Sludge concentration-filtration dewatering/centrifugal dewatering" technology was developed with focal point[3,4], which could reduce the sludge moisture content of production system from 98-99% to 70-80%, the rate of reduction could reach more than 90%; During "The Eleventh Five-Year-Plan", the pollution control of oil sludge  developed from sources reduction toward final reduction, recycling and harmless treatment.
It looks as sticky cream solid, whose industrial analysis data is shown in Table 1.

The data for the grain-oriented and densified bulk [9] which was fabricated by combination of magnetic alignment and spark-plasma sintering processes (MA+SPS) was also shown for comparison.
For comparison, data for the n-type layer in the previously fabricated multi-layered films, the optimized Mn113 mono-layer and a densified Mn113 bulk[10] were also shown.
For this calculation, the data of Th, cold side temperature (Tc) and ∆T [11] measured for the evaluation of power generation in the previously fabricated multi-layered film were used.
The calculated Pmax data were plotted as a function of ∆T in Figure 7.
The measured data [11] of the previously reported multi-layered film were also shown for comparison.

This desiccant wheel is capable of condensing water at 0.05kgH2O/s and providing 3.3639 kW load reduction.
With this significant load reduction, the component integrated in solar hybrid desiccant air-conditioning system can perform comfort cooling to area with high latent load such as hall, hyper market and commercial building. 1.Introduction The emphasis on the design of energy efficient air conditioning systems for both industrial and comfort applications is becoming a priority in the light of continuing rise in energy demand, cost and the environmental problems most notably the climate change.
ADAM data acquisition has been used to do monitoring and recording of temperature, humidity, air flow rate in each stage of air process and also radiation intensity.
Fig.2 Sensible process of desiccant wheel Fig.3 Theoretical and experimental sensible dehumidification Fig.4 Dehumidification Sensible Effectiveness Theoretically, the value of absolute humidity 0.024 kgH2O/kgdry.air at dehumidification process result a reduction to 0.017 kgH2O/kgdry.air while the experimental value is 0.0167 kgH2O/kgdry.air.

There is not much data on mass/heat transfer studies with the use of electrolytic technique.
Because the electrodes are immersed in the electrolyte, the reduction process occurs at the cathode while the oxidation - at the anode.
The following electrochemical reaction (reduction process) takes place on the surface of the cathode
The experiment was carried out in order to be able to transpose later the obtained data to the phenomenon of heat transfer using the heat and mass transfer analogy.
Received data can be used in special heat exchanger with buffer layer in the form of annular gap.
