Varnish and sludge formation are considered as one of the most common problems in lubrication and hydraulic systems. In order to simulate the condition of sludge formation, base stock lubricant (Group 1 API) has been selected and exposed to heat in a laboratory setup. Sludge formation process accelerated in the laboratory scale and solid liquid equilibrium data were extracted. Then solid-liquid...

The purpose of this work was to investigate the effect of multidirectional soccer-specific fatigue on hamstring muscle strength and angle of peak torque. Sixteen male semi-professional soccer players (mean+/-S.D.: age: 21.3+/-2.9 years; height 185.0+/-8.7 cm; body mass 81.6+/-6.7 kg) completed the SAFT(90), a multidirectional, intermittent 90-min exercise protocol based on data from English Cha...

Phased arrays are relatively new tools that have been introduced to NDE in the recent decennium. Phased arrays have unquestionable advantages and open new possibilities of realtime ultrasonic imaging in NDE. However, the common way of designing focusing laws is based on the point source assumption, that is, it is assumed that the element size can be neglected. Since such assumption is valid in ...

• Experimental solubility data of amino acids in KCl and (NH 4 ) 2 SO aqueous solutions. ePC-SAFT modelling solid-liquid equilibria water + acid salt mixtures. Ion effects on the different polarity. The effect L-aspartic acid, L-glutamic L-tryptophan, L-tyrosine, seldomly found literature, was studied at 298.2 K, solutions , for concentrations up to 2.0 mol·kg -1 . In this concentration range, ...
