A Theoretical Model for Vibro-Impact Dynamics of Spur Gears with Tooth Flanks Wear
(Springer Nature, 2020)
The main performance of involute gears operation leads to the appearance of nonlinear dynamic behavior and impact. In this chapter the influence of mild wear of the tooth flanks of gears without machine finishing and surface ...
Comparative analysis of current standards for testing thermal protection of facade carpentry
(Regional Association for Security and Crisis Management-RASEC S4 GLOSEC Global Security, 2021)
The low level of energy efficiency in buildings results in increased energy
consumption for heating and cooling and high carbon dioxide emissions. Insufficient
thermal protection of the exterior of a building contributes ...
Experimental analysis of fire resistance of cly hollow-brick masonsry non-load bearing wall
(Proceeding of the 8th International Conference "Civil engineering-science and practice", Kolašin, 2022)
Testing the clay hollow-brick masonry non-load-bearing wall helps us to understand the behaviour of this type of wall during a fire. It is important to know the fire resistance of hollow brick walls so that we can prevent ...

What is the most relevant method for water absorption determination in ceramic tiles produced by illitic-kaolinitic clays? The mystery behind the gresification diagram
(Sociedad Espanola de Ceramica y Vidrio, 2020)
This study presents the 51 mixtures of ceramic clays characterized by using XRF, XRD, granulometry, and dilatometry analyses. After firing in a 1000-1250 °C range, water absorption (WA) according to EN standards by boiling ...
Fired pressed pellet as a sample preparation technique of choice for an energy dispersive X-ray fluorescence analysis of raw clays
(Elsevier, 2022)
In this paper, the main subject concerns comparing different techniques to prepare raw clay samples for energy dispersive X-ray fluorescence spectrometry (EDXRF). Three kinds of sample preparation procedures are examined,such ...
