Autor: N Morrish, R Mujica-Mota, A Medina-Lara

Publikováno v: BMC Public Health, Vol 22, Iss 1, Pp 1-15 (2022)

Abstract Background Loneliness and unemployment are each detrimental to health and well-being. Recent evidence suggests a potential bidirectional relationship between loneliness and unemployment in working age individuals. As most existing research f

Study of the Hydration Mechanism of Portland Cement with Raman Spectroscopy Applying CO2 Laser Radiation

Autor: D. Quiroz-Portillo, I. Rosales-Candelas, J. J. Soto-Bernal, R. González-Mota, G. V. Vázquez

Publikováno v: Journal of Spectroscopy, Vol 2023 (2023)

This work presents the results by irradiating fresh Portland cement pastes with CO2 laser, at powers of 1.6, 2.0, and 2.4 W, at different water-to-cement (w/c) ratios 0.4, 0.45, and 0.5. Raman spectra show the evolution and accelerated growth of the

An update of IPCC climate reference regions for subcontinental analysis of climate model data: definition and aggregated datasets

Publikováno v: Earth System Science Data, Vol 12, Pp 2959-2970 (2020)

Several sets of reference regions have been used in the literature for the regional synthesis of observed and modelled climate and climate change information. A popular example is the series of reference regions used in the Intergovernmental Panel on

Effects of storage temperature and time on false setting behavior of CPI-S Portland cement

Autor: R. M. Mota, A. S. Silva, V. H. S. Ramos, J. C. T. Rezende, E. de Jesus

Publikováno v: Cerâmica, Vol 66, Iss 379, Pp 321-329 (2020)

Abstract The false setting is when cement stiffens prematurely in a few minutes after adding water. Some variables could cause false setting in CPI-S-32 Portland cement, for example, alkali concentration in the cement, the formation of alite (C3S) wi

Autor: M. Grayaa, S. Vanderick, B. Rekik, A. Ben Gara, C. Hanzen, S. Grayaa, R. Reis Mota, H. Hammami, N. Gengler

Publikováno v: Archives Animal Breeding, Vol 62, Pp 153-160 (2019)

Genetic parameters were estimated for first lactation survival defined as a binary trait (alive or dead to second calving) and the curve shape traits of milk yield, fat and protein percentages using information from 25 981 primiparous Tunisian Hols
