1. A comprehensive review of the advances, manufacturing, properties, innovations, environmental impact and applications of ultra-high-performance concrete (UHPC)Gregor Kravanja, Ahmad Rizwan Mumtaz, Stojan Kravanja, 2024, review article Abstract: The article presents the progress and applications of ultra-high-performance concrete (UHPC), a revolutionary material in modern construction that offers unparalleled strength, durability, and sustainability. The overview includes the historical development of UHPC, covering its production and design aspects, including composition and design methodology. It describes the mechanical properties and durability of UHPC and highlights recent innovations and research breakthroughs. The potential integration of multifunctional properties such as self-heating, self-sensing, self-luminescence and superhydrophobicity, is explored. In addition, advances in nanotechnology related to UHPC are addressed. Beyond the actual material properties, the article presents an environmental impact assessment and a life-cycle cost analysis, providing an insight into the wider implications of using UHPC. To illustrate the environmental aspects, the determination of CO2 emissions is explained using three numerical examples. Finally, various applications of UHPC are presented, focusing on the construction of buildings and bridges. By synthesizing the above-mentioned aspects, this review paper captures the dynamic landscape of UHPC and serves as a valuable resource for researchers and engineers in the field of construction materials.
Keywords: ultra-high-performance concrete, UHPC, manufacturing, mechanical properties, durability, multifunctionality, environmental impact assessment, life-cycle costs

2. Religious capital and religious rewards : a study in the economics of religious lifeSergej Flere, 2012, original scientific article Abstract: Religious life is studied by way suggested by the rational choice theory and the religious capital theory. The basic contentions of the theory on the nature of religious life having to do with an exchange upon a religious market, by firms offering compensators and rewards, and consumers, is considered. In the empirical analysis, it was validated that the independent (religious capital) and dependent (religious rewards of two types) were empirically separate constructs. Cross-sectional analysis of survey data indicated a very strong association between religious capital and institutional and ritual experience rewards within religious life, at a cross-cultural analysis, including Bosnian Muslims, Serbian Orthodox, Slovenian Catholics and US Protestants. The association was confirmed as robust at regression inspection with religious socialization. This extends further support for the empirical validity these novel theories of religious life and extensions of economic analysis into religious life.
