Axion-de Sitter wormholes

Abstract We construct wormholes supported by axion flux in the presence of a positive cosmological constant.The solutions describe compact, one-handle bodies colloquially known as kettlebell geometries.The wormholes are perturbatively stable, RV@ALL but regularity of the Euclidean geometry implies an upper bound on the axion flux.Viewed as no-bound

KAJIAN DESAIN ATRIUM PADA BERBAGAI DIMENSI TERHADAP DISTRIBUSI DAN PERGERAKAN UDARA PADA BANGUNAN BERLANTAI BANYAK DENGAN DENAH BUJURSANGKAR DAN BERVENTILASI ALAMI Studi Model dengan Terowongan Angin

Abstract: An atrium is a type of space which is physically shaped as an enclosure inside the building.It is modified from courtyard or an opened enclosure in middle of the building.This research is conducted to identify the effect of atrium size to the air movement velocity rate and its distribution through the rooms in a square-shaped natural-vent

Tuning Barrier Properties of Low-Density Polyethylene: Impact of Amorphous Region Nanostructure on Gas Transmission Rate

This work focused on determining the factors that are of key importance in the oxygen barrier properties of low-density polyethylene (LDPE).It has been shown that, depending on the type and amount of the low-molecular-weight compound (tetracosane, paraffin wax, paraffin oil) introduced into the LDPE matrix, it can contribute to the improvement or d

Generation of Human Neutrophils from Induced Pluripotent Stem Cells in Chemically Defined Conditions Using ETV2 Modified mRNA

Summary: This protocol describes a rapid and efficient feeder-, serum-, and xeno-free method for neutrophil generation from hiPSCs using ETV2 modified mRNA (mmRNA), which directs hematoendothelial programming of hiPSCs.Hematoendothelial progenitors were cultured PROTEIN WATER TROPICAL LIMON with GM-CSF, FGF-2, and UM171 to expand myelomonocytic pro
