The article represents equipment that belongs to the light industry, in particular non-woven fabric manufacturing techniques and technologies, may be used for felt tightening straightening. describes device constructed by us, which it is possible tighten straighten without creating differently deformed areas, protecting structural composition of treated over entire area increasing strength In a...

Abstract. To increase the sustainability of forming processes such as punch bending, homogenization processed semi-finished product is an essential step in manufacturing process. High-strength wire materials are usually available strip material before being further a For storage and transport, coiled onto coils transported to customer. During coiling process, residual stresses plastic deformati...

The effect of vanadate on the ATP-induced disruption of trypsin-treated axonemes and the ATP-induced straightening of rigor wave preparations of sea urchin sperm was investigated. Addition of ATP to a suspension of trypsin-treated axonemes results in a rapid decrease in turbidity (optical density measured at 350 nm) concomitant with the disruption of the axonemes by sliding between microtubules...

Takotsubo cardiomyopathy can be divided in apical ballooning, mid-ventricular ballooning, and rarely in basal ballooning. The role of left anterior descending coronary artery is still in debate. Spasms, myocardial bridging and recurrent segment (wrap-around) LAD have been described in takotsubo cardiomyopathy. 8 patients (4 females, mean age 74.3 ± 9.7 years) with typical apical ballooning in 4...

The research involved the design of pipe positioning equipment for repair natural gas and oil pipelines. This paper presents results hydraulic straightening device its practical implementation. Several concept calculations analyses were carried out during design. final layout was selected from several possible solutions.

Channelization has changed the form and dynamics of rivers on a global scale. In midwestern United States, widespread straightening meandering headwater streams been undertaken for purpose improving land drainage. Few studies have examined in detail how respond to straightening, especially over timescales nearly century following straightening. This study uses historical aerial imagery contempo...
