Fascinating single‐cell red algae: models for evolution and adaptation
Summary The unicellular red algae, Cyanidiophyceae, that diverged early during Archaeplastida (algal and plant) evolution, occupy a variety of extreme habitats that are inhospitable for most other eukaryotes. With the use of modern genomics and genetics methods, Cyanidiophyceae show a remarkable taxonomic diversity, share haplodiplophasic life cycles ...

Effect of foamed asphalt on the properties of the asphalt mixture with reclaimed asphalt pavement
The paper presents the effects of foamed asphalt modified with synthetic wax (SWLC) and tall oil amidopolyamine (TOA) at 1.5% m/m and 0.4% m/m, respectively, on an asphalt mixture containing reclaimed asphalt pavement (RAP). The experimental plan and research methodology for determining the properties of the innovative foamed asphalt are presented. The

Behavior of mixtures asphalt prepared with asphalts and wax modification
The main purposeof the research was to modify Colombian asphalts with natural waxes to produce warm asphalt mixes and establish its mechanical and dynamic behavior. The studied mixtures correspond to the curves sieved curves called md-10 and md-12 according to the classification of the Instituto de Desarrollo Urbano (IDU).

Optimizing In-Place Density of Asphalt Pavements During Cold Weather Paving in Nebraska [PDF]
Late season paving is common and often performed in colder temperatures, which is the most challenging environment for attaining optimal in-place density/compaction The in-place density of asphalt pavement greatly affects the lifespan of the pavement. It
