Solanum brasilianum Dunal was described by Dunal in 1813 with reference only to an illustration in an 18th century work by Leonard Plukenet. Th e plate is diffi cult to interpret and no explicitly related specimens were available so the name S. brasilianum has long been regarded as “unresolved” and has never been used. Material matching the Plukenet plate was discovered in the herbarium of the ...

In this paper, after collecting the rock samples from eight mines and one high way slope, the tests for determination of dry density, Uniaxial Compressive Strength, tensile Strength (Brazilian Test), elastic modulus, Schmidt hammer rebound number have been done on samples. In addition, in order to calculating the mean size of rock grains, quartz content, hardness and abrasivity, a thin sections...

Rodents constitute one of the most diversified mammalian orders. Due to the morphological similarity in many of the groups, their taxonomy is controversial. Karyotype information proved to be an important tool for distinguishing some species because some of them are species-specific. Additionally, rodents can be an excellent model for chromosome evolution studies since many rearrangements have ...

The objective of the current study was to compare results relating compressive and tensile strength rocks obtained during research undertaken according Polish Standards (as part European standards known as Eurocodes), American Society for Testing Materials (ASTM) Standards, recommendations International Rock Mechanics (ISRM). A total 130 experiments uniaxial compression on axisymmetric samples,...
