Wire injury of an artery has been recognized as a standard model of vascular inflammation and atherosclerosis; however, the mechanism of leukocyte recruitment has not been studied in this model. In this study, we documented the recruitment of leukocytes to the murine femoral artery after a wire injury. A transluminal mechanical injury was generated by insertion of a wire into the femoral artery...

OBJECTIVE To determine potential effects of humidification on the volume of airway secretions in mechanically ventilated patients. METHODS Water vapor delivery from devices providing non-heated-wire humidification, heated-wire humidification, and heat and moisture exchanger (HME) were quantified on the bench. Then, patients requiring 24-hour mechanical ventilation were exposed sequentially to...

The occurrence of non-deformable, non-metallic inclusions is the dominant reason for failure wire during drawing and degrades service life some steel grades, e.g., tire cord steel. To investigate deformability glassy in CaO-Al2O3-SiO2 MnO-Al2O3-SiO2 systems, experimental numerical methods were used. Young’s modulus values glasses based on which correspond to typical steel, measured with resonan...

In this paper we are interested in the dynamics and numerical treatment of a rolling disk on a flat support. The objective of the paper is to develop a numerical model which is able to simulate the dynamics of a rolling disk taking into account frictional resistance against sliding, pivoting and rolling. A mechanical model of a rolling disk is presented in the framework of Non-smooth Dynamics. ...

Atmospheric pressure corona discharges are used in electrophotographic (EP) printing technologies for charging imaging surfaces such as photoconductors. A typical corona discharge consists of a wire (or wire array) biased with a few hundred volts of dc plus a few kV of ac voltage. An electric discharge is produced around the corona wire from which electrons drift towards and charge the underlyi...

We have used time-resolved scanning Kerr microscopy to study spin waves in a magnetic microwire subjected to a bias magnetic field applied parallel to its long axis. The spin-wave spectra obtained from different points near one end of the wire reveal several normal modes. We found that modes of a higher frequency occupied regions located further from the end of the wire. This was interpreted in...

The latest development trend in rolling industry is the combination of various technological operations continuous production lines. In long products, and drawing processes looks promising. A wire mill developed by team authors this work belongs to conceptually new, integrated creation new mills requires a research phase, where relevant concepts are scrutinized using methods mathematical modeli...

The resistance against rolling of a rigid cylinder on a at viscous surface is investigated. We found that the rolling-friction coeecient reveals strongly non-linear dependence on the cylinder's velocity. For low velocity the rolling-friction coeecient rises with velocity due to increasing deformation rate of the surface. For larger velocity, however, it decreases with velocity according to decr...

High pressure multi-layer rolling is an effective method to reduce residual stress and distortion in metallic components built by wire arc additive manufacturing (WAAM). However, the mechanisms of reduction during are not well understood. Conventional finite element models for highly inefficient, hindering simulation large WAAM components. This study aims identify most suitable modelling techni...
