background aeromonas hydrophila cause one of the most important diseases in fishes and lead to economic losses, and may be contaminated human beings. objectives the current research aimed to investigate the anti-bacterial activity shown by the extracts prepared from different parts of olea europea, myrtus communis, thymus vulgaris, rosmarinuis officinalis, and achillea falcata that grow in syri...

A on-line monitoring new method for grinding quality is presented based on theory analysis and test study, which collects the information of grinding quality from the AE signals produced by friction and grinding process to realize the on-line intelligent detection and prediction of grinding quality by A wavelet neural network & Fuzzy BP algorithm based network. The reliability and feasibility o...

The use of aluminum alloys as a material for engineering components that rub against each other is increasing, so it important to know the friction characteristics these alloys. In this study, Aluminum 2024 was given heat treatment with variation in aging time and anodization. Then, wear coefficient tests were carried out using pin tool on disc. effect surface anodization are determine amount t...

A pin-on-disk tribotester has been designed and constructed that enables cryogenic friction wear testing to be conducted either in liquid nitrogen (wet tests) or dry sliding conditions. The tester does not require a sealed, cooled cryostat for the tests. For wet tests, both pin disk specimens are immersed (LN 2 ), whereas specimen is only partially submerged LN while remains gaseous nitrogen. T...

In the context of developing an innovative seismic dissipation system, which aims to compromise on steadiness friction and processes costs, this work deals with tribological characterization S355JR structural steel, whose surface has been preliminarily treated by different mechanical galvanic processes. Tribological tests were performed in a pin-on-disk configuration reciprocating motion, using...

conclusions in treatment of intra-articular distal radius fractures in middle-aged patients internal fixation with locking plates may be prefered to pin and plaster as the treatment of choice. results sf-36 test demonstrated a better general health (p < 0.001), mental health (p = 0.006), physical functioning (p < 0.001), social functioning (p < 0.001) and energy/fatigue (p < 0.001) in lcp group...

This paper presents a software called XGB-COF that uses machine learning algorithm Extreme Gradient Boosting to predict the coefficient of friction (COF) porous AlSi10Mg-Al2O3 composites, tested by pin-on-disk method under dry sliding conditions. The is based on python and various packages for data processing, learning, visualization. aims address research challenge developing enhancing materia...
