Polymer-modified cement-based materials have been widely used in building materials.Polymers play a crucial role in improving the performance of cement-based materials.At the same time, different polymers are added according to specific special requirements to meet the needs of the industry.Therefore, this paper reviewed the research on the perform
Abstract Based on investigations and flow gauges that we conducted in all the foggaras of the Bouda Oasis during the period: 2015–2018, this article examines ULTRA OMEGA-3 an original hydraulic phenomenon that occurred recently in the oasis of Bouda in the wilaya of Adrar (Algeria).The exploitation of the boreholes made during the 1980s in the ex
Abstract We demonstrate a new generation mechanism for polarisation- and colour-entangled photon pairs.In our approach we Potato Mashers tailor the phase-matching of a periodically poled KTP crystal such that two downconversion processes take place simultaneously.Relying on this effect, our source emits entangled bipartite photon states, emerging i
The primary goal of this study is to investigate the effect of increasing battery size and driving range to the environmental impact of electric vehicles (EVs).To this end, we compile cradle-to-grave inventories for EVs in four size segments to determine their climate change potential.A second objective is to compare the lifecycle emissions Door Se
