In fact, Photocatalytic products are a contemporary innovation and play an important role in reducing pollution, thanks to their technology that allows them to be used in several cases: tiles, concrete, paint and floor coverings (Fig. 6). these materials are attracting a lot of interest throughout Europe, especially when applied to traditional surfaces because they are self-cleaning, absorb many pollutants in the air and play an antibacterial effect by transforming the surfaces on which they are applied in multifunctional elements due to solar radiation, anatase, a particular titanium dioxide (tiO2) mineral form, by means of a photocatalyst accelerates the oxidation process by helping pollutants decompose into water-soluble inorganic salts by combining the anti-pollution effect with Antibacterial effect [17].
The bacteria present in the mixture create a calcareous substance able to fill the discontinuities in the stone material of this green-concrete and to reduce and eliminate the cracks in an ecological way to prevent water from coming into contact with the reinforcements.
Once the cracks have formed, the water dissolves the capsules and releases the bacteria increase by feeding on the calcium lactate present in the mixture and so they start to produce calcite or limestone crystals that fix the crack by two weeks. 
Professionals of different disciplines are confronted through a design approach where principles and practices are integrated, aware that Nature is a database of sustainable design innovations, an archive of patents available immediately, an available research and development laboratory, a starting place to face the future challenges on massive sustainability problems.

Population growth in the world has caused an increased demand for resources, energy, food and water.
The importance of forests is critical because they play very important ecosystem roles such as the release of oxygen and carbon capture, maintenance of water and biodiversity, protection against erosion.
Among bamboo’s applications, few should be cited, such as: A) Agriculture: it is used for irrigation of soils and crops; its tubular structure facilitates the water transport from the source to local irrigation [17].
In this way, faced with the current energy crisis, global warming and socio-environmental stresses, the use of non-conventional sustainable materials and technologies becomes a great ally for minimizing the impact of those conventional, and encourage changes in attitudes of professionals involved more specifically in the environmental conservation in Brazil.

.→ fermenting → cooling → finished product Technique procedure: Glutinous rice and grits were soaked in water for 4h and then steamed for 5 min.
After that, stirred up the rounded masses, continued to be steamed for 25 min and then showered them with cool boiled water to about 30℃, inoculating Angel Rhizopus Sp., incubating the materials at Constant Temperature until they had a desirable flavor and taste. 2.3 Measurement Indicators and methods 2.3.1 Sensory evaluation: 10 professionals were chosen to evaluate rice wine and yogurt with rice wine flavor in sense perception.
°T stands for the Unit. 2.3.3 Determination of reducing sugar: The Fehling reagent hot titration method (GB/T 15038-2006) was used: in every 100g of rice wine juice contains glucose's number. 2.4 Flavor analysis of rice wine 2.4.1 Head Space Solid Phase Micro-extraction (HP-SPME) Aromatic compounds from the rice wine samples were extracted by HS-SPME and analyzed using gas chromatography/mass spectrometry. 3g wine sample, 3ml distilled water and 1g NaCl were placed in a 15-mL sample vial.

Standard quercetin (Tokyo Chemical Industry CAT 849061-97-8), standard chrysin (Sigma Aldrich USA CAT 480-40-0), and water for injection (PT.
Quercetin is very soluble in ether and methanol; soluble in ethanol, acetone, pyridine, and acetic acid; and insoluble in water [21].
Research conducted by Dong et al. (2021), stated that chrysin compounds had the highest solubility values in dipolar aprotic solvents, such as dimethylformamide (DMF), acetone, and ethyl acetate, had moderate solubility values in polar protic solvents such as n-butanol, isopropanol, n-propanol, ethanol, and methanol; and had the lowest solubility value in polar aprotic solvents such as hexane and water [24].

As a matter of fact, the subway construction has the characteristics of large-scale investment, long construction cycle, complex professional division of labor, and great technical difficulties, etc., although cooperated-building parties attach great importance to safety management work, the risk accidents still happen often, which causes a great economic loss to the country and produces serious social impacts.
The risk identification expert system is an effective way to solve the above problem, which can effectively utilize experts’ many years of accumulated experience and professional knowledge through simulating expert thinking process. 2.
Flow sand refers to after the soil granular is saturated by ground water , due to the existence of the head, dynamic pressure will make these granular produce suspension flow.
The causes and risk factors include: ①retaining pile or ground even if wall into the rock, ②the variation of water head difference between the inside and the outside,③the basement formation geological, ④the foundation pit bottom weak formation is strengthening or not, ⑤the ratio of the retaining pile the ground wall in the dust, ⑥the soil thickness of the basal. 3.2 Risk identification fact Base Construction In general, fact base consists of fact ID, fact description, status, and facts determination and its credibility,which it can be expressed by table structure.

Water adsorbency at one-side wetting was determined according to GOST 12605-97 (Cobb's method).
The method includes determination of the water weight (g) absorbed by paper surface at wetting one side of the sample for 60 sec.
Inhibitor content of the Fislage's and EuroBum papers is confidential, but identification tests in water extracts based on packaging papers detected nitrite ions [10].
The first adsorbed water molecules can expand gaps between cellulose macromolecules without chemical bond, which facilitates expansion.

The performance of gas lift was affected by a several factors namely the injection depth, valves spacing, wellhead pressure, reservoir pressure, water-cut and many more.
Fig.1 ang Fig.2 show the oil rate with various reservoir pressure and increasing water cut for the injection depth 1068 m, 1222 m and 1490 m.
Fig.3 and Fig.4 show the sensitivity of gas injection rate towards the oil production at various reservoir pressure and water cut.
For this study, analysis was performed on the initial reservoir condition where the water-cut is zero and the result is shown in Table 2.

For cooling slope casting (CS casting), A380 aluminum alloy (Table 1) was melted in a graphite crucible in a resistance furnace and cast into a steel mould (30 mm in diameter and 160 mm in length), via a water cooled slope feed (see Fig. 1).
The semi-solid slurries were quenched in water to observe the microstructure of the semi-solid slurries and they were metallographically examined.
In addition, the solid fraction and sphericity were obtained using the CLEMEX PROFESSIONAL EDITION analysis program.
