occur with the choice of new boundary conditions. Using these more realistic boundary conditions, Yadav et al. [ 4 ] analyzed the thermal instability of rotating nanofluids. The authors mentioned that the
model selected in their study is more realistic physically than those used in the previous studies (i.e., models with non-zero nanoparticle flux at boundaries). Different aspects of natural convection in porous media have been examined thoroughly by many researchers (see, e.g., Ref. [ 5 –9]).

out the anchor for any material and for any length of anchoring.
The HILTI HDA-P M20x250/100 anchor was adopted for pull-out tests. with anchoring length of 25 cm will be used ( “European Technical Assessment…” ), the picture of this anchor is shown in Fig. 1 .
Pre-set undercut Hilti HDA-P anchor.
To mount this anchor, it is placed in a prepared hole in the anchored surface. Then, a drill is attached to the anchor, and while drilling, the anchor undercuts itself with deflecting elements. Scheme of mounting the anchor is shown in Fig. 2

The stocks of coal are crucial areas of coal-fired power plants, in terms of safety, optimization of energy storage and environmental implications (e.g., [ 1 ], [ 2 ]). Although they are now usually protected from rain and wind by storage structures or more simply by coating with tarpaulins, in many old plants in the world these stocks are still exposed to natural climatic conditions such as rain. This climatic condition could allow the air pollution with fine coal particles, as close to mining areas (e.g., [ 3 ]), and leaching processes due to
