Determining the age of ancient architectural and cultural monuments is a significant scientific problem. An approach based on transformation portlandite into calcite subsequent recrystallization considered, which allows for estimating relative brickworks local groups historic buildings results diffraction studies powder samples carbonate mortars measurements with known age. This article present...

We study the unwheeled rational Kontsevich integral of torus knots. We give a precise formula for these invariants up to loop degree 3 and show that they appear as colorings of simple diagrams. We show that they behave under cyclic branched coverings in a very simple way. Our proof is combinatorial: it uses the results of Wheels and Wheelings and new decorations of diagrams.

Many spiders, and in particular those in the genus Argiope, spin highly visible web decorations whose function and significance are the subject of spirited debate. In this work, we present data to address two of the competing hypotheses that fuel this controversy. In particular, we examine the relationship between the presence of web decorations and spider survivorship (predator-protection hypo...

The trend of using modern technologies in the construction industry has been growing stronger recently, particularly fields additive or robotic bricklaying. Therefore, specifically for purpose bricklaying, we created a digital layout plan works. This article presents universal methodology creating bricklaying various variations wall building systems. method is based on conversion drawings from ...

Abstract The research of the mechanical behaviour reinforced and cavity wall brickwork is focus this paper. In paper, casting specimens are done manually totally 18 prepared. different proportions were followed for bricks specimens. used red bricks, fly ash solid bricks. Conventional method using mortar brick prism with constructed finally compressive strength estimated brickworks. obtained var...
