As the shear rate increases, the polymer chains begin to unravel and become partially aligned with the direction of plate motion, which is reflected as a reduction in the viscosity of the solutions (Table 2).
DSC measurements can provide us with very relevant data on the thermal behavior and phase transitions that exist within materials.

However, the addition of 10% recycled ceramic tile powder resulted in a significant reduction in water absorption to 8.9%, indicating enhanced durability.
The central composite design approach was employed to analyze the experimental data and establish the optimal mix composition for maximizing the durability performance of the burnt clay bricks.

For von Mises material model with IF, however, differences between experimental and numerical data of maximal thickening in risk section are observed.
In addition to the processing time, a difference in thickness reduction is observed where the explicit model gives less thickness decrease in the flange edge.

Q1 Capital/cost effectiveness
Q1.1 Production cost of products saving
Cost reduction is a strong reason of cooperation.
After excluding non-manufacturing survey and other non-real-data problems in questionnaires, 145 valid questionnaires were returned to 32.2%.

Combined TGA/DTA data were obtained using STA 449 F3 Jupiter (by Netzsch).
The blending of fly ash from pulverised combustion process with fly ash from fluidized bed coal combustion and with addition of 5 wt.% of gypsum resulted in reduction of anhydrite, vishnevite phase formation and improvement of geopolymer paste strength.

This process consists of repeated fracture, mixing and cold welding of a fine blend of elemental
particles, resulting in size reduction and chemical reactions.
The data for nanocrystalline LaNi5 was also incorporated; lines are provided as a guide to the eye.

At present, the methods of Cr-containing wastewater treatment are ion exchange resin, chemical precipitation, electrolytic reduction, adsorption, biological methods, membrane separation, etc.[3], Commonly used as adsorbents adsorption—modified zeolite was reported frequently, eg. adsorption of heavey metals Pb2+, Co2+, Zn2+, Cr6+, Cu2+ [4-13]. zeolite 4A is a compounds with silicon oxide and aluminum oxide tetrahedron, in the tetrahedral aluminum, the aluminum atoms are trivalent, with one oxygen atom has been in negative [14], in order to remain neutral, then it would be compensate by the positively charged ions [15].
Through the zeolite 4A to the different concentrations of wastewater containning Cr3+ adsorption, with Langmuir and the Freundlich adsorption isotherm data were fitted [11], so the adsorption isotherm shown in Figure 5, Figure 6.

Considering the situation of contraction of teaching hours and reduction of research funding in university, it should not occupy extra classes as far as possible.
A series of links and steps of practice ,including: consulting literature and data, reporting the topics of project, designing steps of the research, implementing it, and writing papers and a concluding report, enables students to learn a lot of things that they can’t learn from the simple classroom, inspires the students’ independent thinking and awareness of innovative, improves their scientific literacy greatly, and makes some students with a strong ability to stand out, and a good foundation for research work in the future.
