Dry hydrated lime is an air binder often used in architectural injection grouts. This study compared the influences of three commercially available dry hydrated limes on the injection grouts workability and mechanical properties. The main differences between the limes were in their chemical and mineralogical composition and Blaine specific surface ...
Geotekstilije so tehnične tekstilije, ki so med drugim namenjene za gradnjo cest, skozi katero voda neovirano prehaja (filtracija), a obenem zadržuje prehajanje delcev zemljine v smeri toka vode (ločevanje). Ustrezati mora specialnim zahtevam objekta nizke gradnje, med drugim tudi, da se njene lastnosti s časom ne smejo bistveno spremeniti. V diser...

The outbreak of the ongoing coronavirus disease 2019 (COVID-19) pandemic has led to the recommended routine use of face masks to reduce exposure risk. In this study, the increase in work of breathing (WOB) imposed by face masks is theoretically studied for both normals and patients with obstructive and restrictive lung diseases at different levels ...

For Ti6Al4V orthopedic and spinal implants, osseointegration is often achieved using complex porous geometries created via additive manufacturing (AM). While AM porous titanium (pTi) has shown clinical success, concerns regarding metallic implants have spurred interest in alternative AM biomaterials for osseointegration. Insights regarding the eval...
This article presents a novel methodology for data integration including laboratory data, the results of standard well logging measurements and interpretation and the interpretation of XRMI imager data for determination of the porosity and permeability of the fracture system in carbonate rock. An example of the results of the micro computed tomogra...
This paper shows the scientific possibilities of computed tomography for the study of concrete porosity. The enormous technological advances in computed tomography equipment used in materials research, with increasingly higher energy, better resolution and smaller pixel size will allow, in the near future, viewing pore sizes that are currently unth...

Activation is commonly used to improve the surface and porosity of different kinds of carbon nanomaterials: activated carbon, carbon nanotubes, graphene, and carbon black. In this study, both physical and chemical activations are applied to graphene oxide by using CO2 and KOH-based approaches, respectively. The structural and the chemical propertie...

The porosity of liver sinusoidal endothelial cells (LSEC) ensures bidirectional passive transport of lipoproteins, drugs and solutes between the liver capillaries and the liver parenchyma. This porosity is realized via fenestrations – transcellular pores with diameters in the range of 50–300 nm – typically grouped together in sieve plates. Aging an...
V diplomskem delu je uvodoma predstavljena tehnologija visokotlačnega litja s poudarkom na njenih prednostih in slabostih. V nadaljevanju je bolj natančno razložen proces visokotlačnega litja znotraj livarske celice in prav tako sta opisana poglavitna elementa tehnologije visokotlačnega litja ? livarski tlačni stroj in livarsko orodje. Omenjeni sta...
