Adding basalt fiber into concrete can significantly improve its mechanical properties. In order to explore the influence of content on uniaxial compressive strength and splitting tensile mechanism action, this paper conducts tests three kinds specimens with different obtains relationship between macro properties content. At same time, help CT scanning equipment digital image processing technolo...

Mass transport of molecular compounds through porous solids is a decisive step in numerous, important applications like chromatography or heterogeneous catalysis. It is a multi-scale, hierarchical phenomenon: macrodiffusion (>μm) is influenced, in addition to parameters like grain boundaries and particle packing, by meso-scale (>10 nm, <μm) factors like particle size and the connectivity of por...

Several methodologies published in the literature can be used to construct realistic pore networks for simple rocks, whereas in complex pore geometry formations, as formed in tight reservoirs, such a construction still remains a challenge. A basic understanding of pore structure and topology is essential to overcome the challenges associated with the pore scale modeling of tight porous media. A...

Abstract A new model for the multi-scale simulation of solute transport in concrete is presented. The employs plurigaussian simulations to generate stochastic representations micro- and meso-structures. These are idealised as two-phase medium comprising mortar matrix pores micro-structure, large aggregate particles meso-structure. generated meso-structures employed a finite element analysis ste...

It is known that the essential ingredients of a Lisp-style unhygienic macro system can be expressed in terms of advanced hygienic macro systems. We show that the reverse is also true: We present a model of a core unhygienic macro system, on top of which a hygiene-compatible macro system can be built, without changing the internals of the core macro system and without using a code walker. To ach...

A soil’s physical properties, mineral types, and pore structure significantly influence the shape properties of soil-water characteristic curve (SWCC). This study investigated effects types on SWCC pore-size distribution (PSD). Eight different soils from an alluvial deposit in Istanbul Adapazar?/Türkiye were used study. The test samples prepared by compaction at optimum water content (OWC) wet ...

The paper presents an algorithm for multi-agent strategic modeling (MASM). The method applies domain knowledge and transforms sequences of basic multi-agent actions into a set of strategic action descriptions in the form of graph paths, agent actions, roles and corresponding rules. The rules, constructed by machine learning, enrich the graphical strategic patterns, which are presented in the fo...

Synthetic routes for the preparation of O-acetyl-ADP-ribose and two novel non-hydrolyzable analogs containing an N-acetyl are described and shown to interact with the macro domain of histone protein H2A1.1.

4 ABSTRACT: Anaerobic digestion (AD) of the organic fraction of municipal solid waste (OFMSW) 5 is promoted as an energy source and more recently as a GHG mitigation measure. In this context, AD 6 systems operating at thermophilic temperatures (55-60C) – compared to mesophilic temperatures 7 (35-40C) – have the unique feature of producing hygienic soil conditioners with greater process 8 effici...
