Quartz sand with a maximum grain size of 2.5 mm was used as aggregate.
Changes of a dominant frequency in impact-echo method towards lower values for all three specimens are not negligible and indicate that a large number of new inhomogeneities appeared in the tested specimens 72 hours after they were demoulded.

It is also seen that though the grains tend to become finer with the increase of Cr3C2 content and various phases are the most evenly distributed in the composition of 0.6% Cr3C2, which is consistent with the research by Yong Zheng [5] et al.
The research by Lin He et al [6] showed that Cr content is the most in the binder phase and the least in the hard phase and the number of Ti (C,N) particles decreases gradually from the binder phase and some Cr3C2 particle that are not totally dissolved are scattered in the binder phase and at the phase boundaries, thus refraining cracks, which is consistent with the conclusion that the KIC is the best in the composition of 1.2% Cr3C2.

Natural selection has favoured the evolution of a variety of shell adaptations in some groups of amoebas, e.g. in Diflugia, the shell is made of tiny sand grains cemented together in a kind of miniature upside-down vase; in Arcella, the shell is constructed from the chitin (protein-sugar compound); in Euglypha, thin siliceous plates are produced and deposited in the outer layer of the amoeba's body.
Conidiophores are reproductive structures that enable some filamentous fungi to produce and disseminate large numbers of asexual spores.

Introduction The study of porous medium has gained considerable momentum in last few decades because of its significant role in many scientific and engineering applications namely geothermal heat extractions, nuclear reactor waste disposal, heat exchangers, electronic components, solar energy storage technology, exothermic reactions in packed bed reactors, storage of grains, food processing, and the spread of pollutants underground etc.

Although the dominant intrinsic strengthening mechanism in typical Co-Cr-Mo alloys is secondary phase strengthening due to various precipitates [12, 13], the low number of those found in the SP2_AS sample is likely to have a very small effect on the mechanical properties.
The TEM investigation of the Ti64_AS sample (Fig. 3(b)), shows the α acicular microstructure which is typical of metal parts subject to high cooling rates [8], with a high density of dislocations inside the lamellar grains and rare twins.

Crop climate potential productivity estimate is the basis of enhancing grain comprehensive production ability, and it can provide important theoretical guidance for the agricultural productivity layout, agricultural structure adjustment and ensure the national food security.
At present, a large number of researches are based on a regional climate potential productivity’s time-space distribution characteristics.

With the ninth super typhoon storm Muifa large number of infiltration slope body, FEDCB, upper slide zone soil water seepage recharge saturation, slope body soon in full water state, and the original slope FGHI flowing water and mud.
The slope of rock and soil layer is grain filling, silt clay, weathering slate.

In addition, a large number of rounded grains with the film thickness of ~150 nm were observed in a cross-sectional SEM image of TiO2 film (Fig. 2(b)).

The quartetin content in each replication stated as the equivalent of a newsletter is a general reference for measuring a number of queries contained in a material Result and Discussion Table 1.
The influence of total phenols content on antioxidant capacity in the whole grain extracts.

Introduction The Pearl River Delta is a relatively developed region in China, in recent years a large number of projects such as highway, railway, municipal roads, skyscrapers and large buildings ect., the widely distributed modern sedimentary soft soil in the region brings great difficulties to the constructions of different projects due to its high moisture content and compressibility, low strength, high plasticity index and low permeability.
A lot of research and practice has confirmed that in addition to its material composition and grain composition, the engineering properties of soft soil are closely related to the microstructure of the soil and dominated and controlled by it, such as the shape, distribution, mode and connection of particles, the morphology, scale, cemented form, voids scale and porosity of micro-particle polymers etc [3-4].
