With modern production, Minimum Quantity Lubricant (MQL) technology has emerged as an alternative to conventional liquid cooling. The MQLs is an environmentally friendly lubricant method with low cost while meeting the requirements of machining conditions... see more

Combustion instability in rocket engines is accompanied by large-amplitude pressure fluctuations in the combustion chamber and (or) intense vibration of the load-bearing structural elements. Unstable operation leads to a decrease in thrust, specific impul... see more

Several researches have shown that P-wave velocity carries information on the complexity of the rock's pore geometry and pore structure. Their complexity can be characterized by critical porosity. Therefore, the P-wave velocity is used to estimate permeab... see more

The endangered Indo-Aryan language Mankiyali, spoken in northern Pakistan, lacks linguistic documentation and necessitates research. This study explores the Voice Onset Time (VOT) values of Mankiyali's stop consonants to determine the duration of sound re... see more

Gas hydrate is a type of hydrocarbon formed like crystals and is formed in the seabed sediment layer. Water temperature and pressure affected the area where gas hydrates are formed; gas hydrates are composed of gas and water elements. Gas hydrates have th... see more

At this time the research related to the effect of magnetostriction for underwater applications is still limited. Acoustic or sound waves are more easily propagated underwater than electromagnetic waves or light. An acoustic wave or sound can be generated... see more

The increased use of metal additive manufacturing in production components makes quality control essential. The performance of parts produced by laser powder bed fusion depends on optimal process-parameters and the careful selection of scanning and buildi... see more
