Effects of pigment volume concentration on radiative cooling properties of acrylic-based paints with calcium carbonate and hollow silicon dioxide microparticles

چکیده
Radiative cooling paints offer a sustainable method for reducing energy demand in buildings. This work investigates the effects of particle volume concentration (PVC) calcium carbonate (CaCO3) and hollow silicon dioxide (SiO2) microparticles acrylic-based on capability. Paint solar reflectance increases as total PVC until peak is reached. The addition CaCO3 improves due to an enhancement near-infrared reflection but decreases thermal emission. paint, with 0.45 CaCO3:SiO2 ratio 1:1, offers right balance between emissivity achieves best performance. demonstrates that CaCO3-SiO2 paint system allows tuning radiative

the effects of previewing and providing background knowledge on iranian university efl learners’ comprehension of literary and academic texts
abstract poor reading comprehension can result in failure in using references, benefiting from professional gatherings and resources, keeping up with the growing body of knowledge in the virtual world of the internet, and failing to achieve in efl programs. the purpose of the present quasi-experimental study was to explore the effects of background knowledge and previewing narrative and expos...
15 صفحه اولsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
