This research aim to study the Influence of mix proportions on the impact resistance of high strength concrete, Trial laboratory batches were used including as follows: -Normal concrete mixture (C1) as a reference mix ((w/c) = 0.45, without admixtures);-Four concrete mixtures (C2, C3, C4, C5) prepared by fixing (w/c)…

Cristobalite is a high-temperature, low-pressure polymorph of SiO2. It is comprised of a framework of SiO4 tetrahedra,like many other low-pressure silica polymorphs, e.g. quartz tridymite, or coesite. Its cubic form knownas -cristobalite crystallizes above 1470 °C and at atmospheric pressure. The tetragonal -phase is…
Recently, the widespread interest on soil enzymes is due to the need to develop sensitive indicators of soil quality that reflect the effects of land management on soil and assist land managers in promoting long-term sustainability of terrestrial ecosystems. The activities of six important enzymes involved in C, N, P,…
Herein we designed and characterized films composed of naturally derived materials for controlled release of proteins. Traditional drug delivery strategies rely on synthetic or semisynthetic materials or utilize potentially denaturing assembly conditions that are not optimal for sensitive biologics. Layer-by-layer (Lb…
n recent years, several studies have focused on the growth conditions of the diamonds through the analysis of the mineral inclusions trapped in them (Howell, 2012 and references therein). Nevertheless, to obtain rigorous information about chemical and physical conditions of diamond formation, it is crucial to determin…
A large field (about 100 km in E-W length and 15 km in N-S thickness) of Oligocene pegmatites extends in the \ncentral Alps from the Bergell pluton (to the east) to the Ossola Valley (to the west) within the Alpine nappes north \nof the Periadriatic Lineament. The pegmatite field geographically overlaps (i) the highes…
In this study, two model drugs, ciprofloxacin (CFX) and ethacrynic acid (ECA) are intercalated in layered zinc hydroxides (LZH) and layered double hydroxides (LDH) host materials via either anion exchange or co-precipitation methods. Four intercalation compounds are obtained, designated as Z–CFX, AEZ–ECA, CPZ–ECA and…
Area-based information obtained from remote sensing and aerial photography is often used in studies on ecological footprint and sustainability, especially in calculating biocapacity. Given the importance of the modifiable areal unit problem (MAUP; i.e. the scale dependency of area-based information), a comprehensive u…
A discrete blast within granular material, such as a single subterranean explosion within a debris-filled diatreme structure, is typically considered to produce a single uprush of material. Our experiments demonstrate that apparent “debris jet deposits” can be formed by a two-stage process of cavitation and subsequent…
This paper presents the research results obtained in ERA NET MANUCOAT project, coordinated by INCDTP in collaboration with the following partners: INCDMNR-IMNR, SC MGM STAR CONSTRUCT SRL –Romania and IRIS-Spain. The objective of the research was to develop and obtain textile and wood surfaces with self-cleaning, photo…
The structural characterisation of macromolecules via X-ray crystallography requires the generation of diffracting protein crystals. However not all proteins are amenable to crystallisation, thereby presenting a rate-limiting step in the technique. High-resolution structural information affords a comprehensive underst…
This article highlights the efforts that need to be put in order to maintain and build nuclear power plants to ensure a reliable source of electric generation. With increasing carbon restrictions and the growing demand for electricity, reliable, carbon-free baseload electricity generation is more important than ever f…
This article elaborates the evolution of code and standards for nuclear power plants. In the 1950s, need was felt for a revised set of design and fabrication rules to facilitate the development of safe, economically competitive water-cooled reactors contained in pressure vessels. These rules were codified in the first…
