Aims: The aims were to assess the influence of tibial bone mineral density (BMD) and cement viscosity on cement mantle thickness in total knee arthroplasty (TKA), and to determine whether BMD is a more dominant factor th...

Abstract Northwest Pacific sedimentary eolian dust flux records have long been used to make direct inferences about Asian interior aridity. However, factors other than aridity can impact dust production rate. We present ...

Abstract Thick-hard roof fracturing presents a significant challenge for disaster prevention in longwall mining. This study investigates the 15,311 south working face and develops a mechanical model to analyze energy rel...

Abstract The study included thirty-six isolates of rhizobia bacteria were isolated from the nodules located on the roots of nine types of leguminous family plants that were planted in four areas of the city of Mosul for ...

Metasurfaces, consisting of arrays of subwavelength structures, are lightweight and compact while being capable of implementing the functions of traditional bulky optical components. Furthermore, they have the potential ...

The vibration-induced liquefaction in soils is a notable hottopic in geotechnical engineering. The building collapse and embankment burst induced by liquefaction are fatal for the loss of lives and properties of human be...

Transparent brittle materials such as glass and sapphire are widely concerned and applied in consumer electronics, optoelectronic devices, etc. due to their excellent physical and chemical stability and good transparency...

Latest Maastrichtian climate change caused by Deccan volcanism has been invoked as a cause of mass extinction at the Cretaceous-Paleogene (K-Pg) boundary (~66.0 Ma). Yet late Maastrichtian climate and ecological changes...

The article is devoted to the research of the place of the mathematical word problems in the course of mathematics of primary school in Ukraine. The researchers define the results in the study of solving math problems, f...

To investigate the influence mechanism of roof pre-splitting blasting on overlying strata movement in automated roadway formation without coal pillars, the mechanical response characteristics of the bearing structure of ...

The Jebel El Onk region presents a complex geological history, starting with Maastrichtian limestones. Early Paleocene subsidence intensified, leading to the deposition of thick marly horizons and black marl shales durin...

The presence of evidence of depredation in ostracods valves from marine and freshwater environments of the central region of the republic Argentina are studied in this paper. In samples from intertidal environment (Puert...

“El presente proyecto consiste en un estudio de pre-factibilidad para el desarrollo del mercado de proppant en la Republica Argentina. En el mismo se explica detalladamente todo el proceso operacional de las perforacio...

The present chapter explores how the distinctive characteristics of magnetic nanoparticles (MNPs), particularly when at different interfaces, account for many novel potential applications in the oil industry. According t...
