However, the size effect in BaTiO3 ceramics such as MLCCs is a complicated phenomenon because of the coexistence of factors such as internal stress, grain boundaries, etc. in addition to the grain size.
This result suggested the possibility of faster particle growth rate with increasing number of contact points between BaTiO3 nanoparticles. 002 and 200 planes of the BaTiO3 nanoparticles prepared from BTO-A and BTO-B are presented in Fig. 3.

This film would bind the hydration product and un-hydrated cement grains to form the structure [8], thus increase the early strength of CAM; however, the asphalt film that formed too early would cover the cement grains thus retarded the cement hydration.

The Lisbon Metropolitan System (Metropolitano de Lisboa), presently comprising stations of different sizes, in 46 locals, inaugurated between 1959 and 2007 [6], constitutes a well-suited set for these studies due to the great number of stations and the diversity of stone materials used.
There are occurrences of surface irregularities in biotite-rich coarse-grained porphyritic granitic rocks applied in pavements (Fig. 3) that seem to specially affect yellowish slabs (yellowish discolouration in these rocks indicates weathering inherited from the quarry that affect physical properties of stones, causing, among other effects, physical weakening and increased porosity).
Fig. 3: Surface irregularity on coarse-grained granitic biotite-rich yellowed stone slabs at Campo Grande station (inaugurated in 1993, [7][8]).

For example, present implementations comprise a large number of security classes (SC).
While in operating systems access classes are assigned to files, database systems can afford a finer-grained classification.
However, the support of fine-grained classifications together with the obvious constraint of maintaining secrecy in the system operation introduces complications.

The average grain size of the received sheet is 20~30μm.
The part blank is aluminium alloy 5083 sheet, its thickness is 1mm, its average grain size is 20~30μm.
According to the research results on thickness distribution，void number and void size in free bulging specimen, if the minimum wall thickness of the parts is not less than 0.5mm, then the formed parts can be recognized as qualified.

Comparing it with both PZTN home-made diffrattrogram (Fig. 1) that with lead zirconium titanium Oxide Pb(Zr0.52Ti0.48)O3 (PDF card number 22-1086) no perovskitic phase (PZTN) was found in detectable amount.
The SEM micrograph reported in Fig. 2 shows an inhomogeneous PZTN microstructure composed by a mixture of fine grains of two or more different phases.
The two different ensembles of colored grains in the top layer are due to the presence of phases with different density.

PSC frost resistance was determined by reducing the compressive strength and weight loss of the samples after a given number of cycles of their multiple alternating freezing and thawing under the following conditions: water as saturation medium; air as environment and freezing temperature of minus (18 ± 2) °C; water as environment and thawing temperature of (20 ± 2) °C.

The first provides a limited time heating and cooling rate increased at high temperatures and prevents the growth of austenite grains to form a low strength of equilibrium structures.
Steel 5155 (AISI / SAE USA) was selected as a base metal which has a high number of mechanical properties.
The first provides a limited amount of time the heating and increased cooling rate at high temperatures and prevents the growth of austenite grains to form a low strength, equilibrium structures.

The size of original β grains is in millimeter scale, consisting of lamellar α colonies in scale of 400~600 μm.
After directly hot rolled by various numbers of heats and successively heat treated, the microstructures of low-cost Ti-6Al-4V plates are composed of primary α phase (αp) and transformed β, as shown in Fig 2 (b) ~ (g).
After one heat hot rolled from 240 mm thick to 85 mm thick, large β grains are significantly refined.

The average grain size of the slag obtained by laser granulometry was d50 = 15.5 µm and d90 = 38.3 µm.
Since all properties were tested on mortars, standard quartz sand with maximum grain size of 2.5 mm was used as aggregate.
Such effect can be explained by a higher number of contacts between fibres for the samples with more than 2% of conductive admixture.
