In this sense, several methods of cooling and / or freezing, such as, cooling with water, air, air-water and vacuum are used in practice [12].
However, during freezing, the water contained in the material changes from liquid to ice phase.
Following, the fruits were washed in water stream for withdrawn of the chlorine excess.
The water-ice phase change has the advantage of fixing the cellular tissue structure and separating the fraction of water at the boundary of the ice crystals.
What is wanted to show, in fact, is the versatility and the applicability that has the mathematical model presented here, which in fact was proven, and to help professionals with interest and expertise in this important topic.

We derived the dependences describing how the bioresistance coefficient, the elastic modulus and the water demand depend on the granulometric composition after 3 and 9 months of aging in the environment of filamentous fungi.
It is necessary to get high volume content of maximum concentrated suspension component having low water demand of concrete mix [20, 21].
Elastic modulus (a) resistance coefficient and water demand (b) dependences on granulometric composition after 3 months of aging in the environment of filamentous fungi.
Elastic modulus (a) resistance coefficient and water demand (b) dependences on granulometric composition after 9 months of aging in the environment of filamentous fungi.

With the production water injection pump unit consumption data for training data, prediction results show that this method can achieve good prediction effect.
It[3] proposed modeling methods that based on the neural network and multivariate statistical analysis of the dynamic prediction, It is improved to a single sequence network prediction, It improves the performance of the network[4-6] .Because of the above methods or depend on professional knowledge, or only applies to certain special circumstances..
QPSO optimized BP neural network chart Experimental Result This method has been used to in a energy saving production information system, Verify the actual data to the first production ore key energy consumption equipment water injection pump unit consumption.
Forecasting water injection pump unit consumption main need three parameters, motor actual operating voltage, the motor operation current and water injection pump of the actual flow.

The Comparison of Au/C Catalyst and Au-Pd/C Catalyst for the Oxidation of Glyoxal to Glyoxylic Acid by Oxygen Xiaoli Wang1,2,a, Shuangcheng Bao2,b and Meilin Jia2,c 1 Professional College, Inner Mongolia Vocational College of Chemical Engineering, Huhhot, 010070,China 2 College of Chemistry & Environmental Science, Inner Mongolia Normal University, Huhhot 010022,China a404782509@qq.com, bshuangcheng@imnu.edu.cn, cjml@imnu.edu.cn Keywords: Bimetallic Catalyst, Glyoxal, Glyoxylic Acid Abstract.
Before use, the carbon was suspended in HCl 2mol/L for 6h, then washed several times with distilled water until the pH of the solution reached values of 7.
Au-Pd/C catalyst: An aqueous solution of PdCl2(0.0385mol/L) was added under vigorous stirring to 100ml distilled water which contains a certain amount of above-mentioned Au/C catalyst and reacted for 0.5h, then NaBH4 solution (0.1mol/L) which was freshly prepared was added.
Glyoxal (2.5ml, 40%) and 0.2g catalyst were mixed with 200ml distilled water in a 4-mouth flask(500ml) provided with an electric stirrer and reflux condensing tube.

The third part uses the professional statistical analysis software SAS to draw the shellfish and algae carbon curve of marine ranching construction, which provides theoretical reference for considering the carbon sink function of marine ranching construction.
Algae fix inorganic carbon by photosynthesis, and make it into carbohydrates, which provide the basis for productivity of waters[3-6].
A ton of waste paper can produce good quality recycled paper 850 kilograms, saving 3 cubic meters’ wood, at the same time can water-saving 100 cubic meters, saving 300 kilograms of chemical raw materials, saving coal 12000 tons and saving 600 degree [11].

Its water level to move rapidly, when moved to the d-hole near the water level, due to the dynamic pressure of the water caused by the high speed rotating head chassis hold up activities, pressing separate cylinders and closed slag s, this is a sealed condition.
This stage is usually very short, only about 5 seconds, safe water must not be too long, otherwise, Active chassis will move to a lower water level, by m holes into a lower part of the chassis p relief activities water, Active chassis back drop.
Compensation conditions For min oil machine by Min water machine work Shi, in oil entered separation tube Qian, must in separation tube within established water seal, is Dang electromagnetic valve open Shi, separation tube of above on can introduced water seal water, electromagnetic valve, open, water seal water entered high speed rotating of separation tube, until sewage export has water outflow weizhi, said water seal area has been by established.
Oil over into out of the partial separation of the water seal water and built up a stable of oil-water interface within the separation tube, oil will also be continuous.
Latter stages of slag, according to oil separator to extend open water water solenoid valve, isolation tube continues to introduce water to water, to flush out the accumulating over the separation of waste slag that cannot be automatically discharged.

Base on renewal transformation practice of urban buildings, firstly new green reconstruction ideas are put forward aiming at improving and enhancing work performance and safety performance of urban buildings, enhancing ability resist earthquake, typhoon, etc, guaranteeing the safety of people's lives and property, improving the efficiency of resource utilization, energy-saving, land-saving, water-saving, material-saving, protecting and improving the environment, prolonging service life of existing buildings.
The consequences are more than the huge waste of the social resources, and a lot of architectural garbage were piled up around the city, lands were occupied, some of them contains many kinds of the harmful chemicals, which corrode the land surface and pollute the underground water, the human survival environment is damaged at the same time, tearing down old buildings and then constructing new ones blindly destroys the city’s historical landscape ,weakens the city cultural inheritance, thousands of the citys’ style is identical, the urban style were damaged heavily.
The existing urban buildings renewal transformation technical standard system concerned many specialties which ranges from exploration, inspection, identification, evaluation, design, construction, to acceptance of project, and the operational management including construction, structure, structural fire protection ,building energy saving, building electricity, central heating and air conditioning, water supply and drainage, intelligent building, building monitoring and identification and so on was made.
Before the urban building renewal transformation is executed the reliability assessment and evaluation of the building should be taken at first, such as structure reliability, state of maintenance health, architecture function and peripheral public environment, condition of the architectural energy-saving, and fire protection system, water supply system, HAVC system, power supply and lighting system, intelligent system and safety hardware facilities.
It includes multi-professional factors of the existing buildings: buildings, structures, fire control, energy-saving, electricity, heating, ventilation, air-conditioning, supply and drainage of water, intelligent, monitoring and identification of houses.
