The differentiation between data and information is highlighted in [12], where data is presented as “the raw material from which information is developed”.
It consumes information and/or material supplied by upstream processes and transforms them to fulfill the need of downstream processes.

Experimental Section Materials. 1,3-dichloro-2-propanol and n-propanol were purchased from J&K Scientific Ltd.
All the materials were used directly without further purification.
This positively charged molecule could be adsorbed on the surfaces of casings, drilling strings, rocks and even the particles of weight materials, while its long oleophilic alkyl chains will spread into the fluid and cover the solid surfaces with a lubricant film.

The corresponding values of the value of Q-factor of the materials are calculated by the expression [8], where - wavelength in meters, and - attenuation factor in Np/m.
It follows that the symmetrical and asymmetrical multilayered structure in Fig. 1 and Fig. 2 from below and from above should be covered with "ballast" layers of materials with high acoustic resistance (larger than silicon).

Introduction The demand for devices and components with high structural performance and geometric complexity has intensively driven the evolution of composite materials.
Technological innovations in structural applications have been achieved by combining multiphase solids in order to obtain new composite materials.

Marking and Evaluating Index of Scientific Research Nurturing Teaching in Universities Yang Weijun1,a, Zhang Guijin1,b, Zhang Tingting1,c,Yuan Shuai1,d 1Changsha University of Science & Technology, Changsha, 410076 amgbyrh@163.com, bgizhang98@yahoo.com.cn, c691762880@qq.com, dicetuo81@hotmail.com Keyword: higher education quality; teaching making; evaluation index Abstract: Experts and scholars have debated for the relationship and importance of university researching and teaching for a long time, owing to the problem that classroom teaching is not attached importance exists objectively, and becomes more serious.
New achievement, new theories and new applications of science and technology are emerged in an endless stream, which objectively needs college teachers to stand for the frontier of knowledge development, update and supplement the knowledge to meet the need of cultivating creative talents.
This course involves related mechanical problems of the stable deformation of engineering, seepage, displacement and structure aging, material and so on.

Quantum dots (0D), also known as nanocrystals, are a special class of materials known as semiconductors, which are crystals composed of periodic groups of II-VI, III-V, or IV-VI materials.
At these small sizes materials behave differently, giving quantum dots/nanoparticles unprecedented tunability and enabling never before seen applications to science and technology.
Template materials must meet certain requirements [5].

The content visualized will be a rough layout enriched by material flow and process information.
For instance, new materials could lead to improved cutting and bonding technology.
Figure 2: Illustration of the proposed systematic Since the interrelations between different production levels need to be considered, on every level of the production system the impact with its respective scenarios can be visualized in different degrees of abstraction (e.g. material flow simulation, process simulation, layout planning).
