PERFORMANCE OF LIGHTWEIGHT FOAMED CONCRETE PARTIALLY REPLACING CEMENT WITH INDUSTRIAL AND AGRICULTURAL WASTES: MICROSTRUCTURE CHARACTERISTICS, THERMAL CONDUCTIVITY, AND HARDENED PROPERTIES

The production of eco-friendly concrete has been made possible by reusing agricultural and industrial wastes.This paper presents an experimental investigation of the characteristics of lightweight foamed concrete (LWF) produced from a protein-based foaming agent and including granulated blast furnace slag (GGBS), fly ash (FA), rice husk ash (RHA) a

The photochromic properties of oxygen-containing yttrium hydride thin films are directly Pop-Up Sofabed dependent on the oxygen concentration in the material.We use 16O/18O labelling to study oxidation of YH2 films.Oxygen penetrates the film through grain boundaries and intercolumnar voids oxidising the whole film thickness, without pronounced surf

Lithium dialkylcuprates undergo conjugate addition to thiochromones to afford 2-alkylthiochroman-4-ones in good yields.This approach provide an efficient and general synthetic approach to privileged sulfur-containing structural motifs and Pop-Up Sofabed valuable precursors for many pharmaceuticals, starting from common substrates-thiochromones.Good

Irma Virant-Klun Department of Obstetrics and Gynaecology, University Medical Center Ljubljana, Ljubljana, Slovenia Abstract: In spite of generally accepted dogma that the total number of follicles and oocytes is established in human ovaries during the fetal period of life rather than forming de novo in adult ovaries, some new evidence in the field
