The Impact

A new soil water characteristic curve (SWCC) experiment contemplating urea concentration is presented in the paper. We focus on the impact of the SWCC considering urea concentration test method for materials selection and introduction, experimental results, and finally, we have conducted some experiments of SWCC and obtained some valuable data which could affect urea concentration. By using linear fitting, an exponential function between water content and suction and urea concentration is established.

AbstractSSZ-based ceramics were obtained by sintering of nanopowders derived at room temperature by mechanochemical synthesis from refined technical grade ZrO2 nano-precursors. RT-treatment by 2.5 MeV electrons up to 1563 K was used for the modification of ceramics. Powders and ceramics were characterized by XRD, Raman, SEM and EDS, TEM, SIMS techniques. The phase composition of Zr0.89Sc0.1Ce0.01O1.95 ceramics was very close to cubic structure but better fitting of XRD patterns was obtained for rhombohedral lattice. Conductivity of solid electrolytes for IT SOFC was studied by complex impedance method. To stabilize cubic structure and increase conductivity at operation temperature of To ∼ 1000 K, the composition of SSZ solid electrolyte was optimized by addition of yttria and sintering aids. The interaction of admixtures with minor dopants leading to intergrain phase was revealed. During fast sintering, ceramics keep a memory about inhomogeneous disordered solid solutions in a form of nanostructuring. Conductivity data indicate nanostructuring of ceramics too: activation energies of bulk and grain boundary conductivities are close (Eb ∼ 0.9 eV, Egb ∼ 1.05 eV). Annealing of ceramics at high temperatures increases conductivity at To and promotes grain growth.

The purpose of this study was to determine the effect of substitution ketapan seed to chemical and organoleptic properties of  the resulted snack food, knowing the exact level of substitution, so obtain the snack food liked the panelists. The design used in this study was completely randomized design (CRD) with single factor that influences the concentration of seed flour substitution ketapan seed consisting of 5 treatments. Each treatment be repeated 3 times. The data obtained was analyzed by Analysis of Variance (ANOVA), if there was a difference between the treatment of advanced test conducted by Duncan`s Multiple Ranges Test Method (DMRT) at the level of 5%. Substitution of wheat flour with ketapan seed flour  affects the snack food produced, which can reduce the water content of the snack food and increase levels of protein and fiber snack food. Ketapan seed flour substitution preferred by the panelists was substitution ketapan seed flour up to 30% with a value of 3.52 and the criteria snack food produced had a water content of 3.67%, 15.10% db protein content, fiber content of 3.64 % db, brownish yellow color (2.95), a rather tasted wheat flour (3.35), and crispy (3.60).

The thin plate penetration test method was presented by Professor T.S. TAN for the determination of undrained strength in high water content sludge. Based on the method, a thin plate penetration test device is designed. Through the thin plate penetration indoor test of dredged sludge, the unload weight and interval time of this test method are studied. The results shows that: if the water content range of soil sample can be segmented, and determine the appropriate interval time for unloading in each segment of the water content range, the efficiency and accuracy of thin plate penetration test method can be improved.
