Erosion problem in tool steel using cold box core-making process por Rodríguez, Eduardo, Pérez, Alberto, Mercado Solis, Rafael David, Velasco Tellez, Abraham, Jiménez, Omar, Flores, Martín, González, Marco Aurelio, Ibarra, Jesús

“…The main results are summarized as follows: (i) The harder material, the lower erosion; (ii) the maximum erosion rate is at 30°; (iii) Little difference in erosion rate at impact angle of 60° and 90° for a constant pressure tested regardless of the hardness level; (iv) As the pressure increases, so does the erosion rate, being more sensitive for low impact angles. …”

The influence of habitat fragmentation on genetic diversity of a rare bird species that commonly faces environmental fluctuations por Canales Delgadillo, Julio César, Scott Morales, Laura Magdalena, Korb, Judith

“…Although we can not exclude that is too early to see an impact on the genetic level, we think that these results might be explained by the species ’ biology: like many other birds living in arid areas, the Worthen’s sparrow has a nomadic lifestyle; depending on local conditions individuals flexibly move between areas. …”

Nutritional role of the natural productivity and formulated feed in semi-intensive shrimp farming as indicated by natural stable isotopes por Gamboa Delgado, Julián

“…As in the natural ecosystems, these dietary components exhibit differing isotopic signatures at natural abundance levels and since these natural communities belong to different trophic positions and isotopic values of organisms tend to increase with trophic level, the isotopic differences can be measured and used to infer on the transfer of nutrients, hence allowing establishing relationships between consuming organisms and their diets. …”

Effect of minerals admixtures on high-performance concrete: C-S-H formation and physical-mechanical properties. por Rivera Torres, Jorge Maurilio

“…However, in most cases, the performance of a cementitious material is typically evaluated through the impact on the mechanical properties and the cost, leaving aside the durability and the effects at the microstructural level. This work intends to study the effect of supplementary cementitious materials on formation of C-S-H and the development of the concrete microstructure. …”
