transmission towers have been subjected to alternating loads caused by the galloping of iced conductors for a long time, and their fastening bolts are easy loosen or break, which seriously threatens safe operation lines. Through transverse vibration test M20 commonly used in towers, frequency amplitude changed, change law preload bolt joints is studied. The results show that with increase initi...

With the development of automobile electrification and intelligence, demand for electro-mechanical braking (EMB) systems is increasing rapidly. This paper reviews status EMB actuator on basis extensive patent literature research. By analyzing basic structure actuator, this decomposes into five modules: service brake module, parking clearance compensation quick-return module sensor module. On st...

The purpose of this study is to compare the performance of laparoscopic partial nephrectomy (LPN) with and without clamping of the renal artery and to evaluate the impact of clamping on postoperative renal function. A total of 20 patients underwent LPN, 13 without and 7 with clamping of the renal artery. The 2 groups were compared with respect to complications, blood loss, operative time, mean ...

Electrophysiological measurements, in particular, patch clamping, have long been regarded as the "gold standard" for assaying ion channels. Despite its high information content, the technique suffers from laborious, manual processing by highly skilled workers and extremely low throughput. Recently, a number of researchers have started to automate patch clamping by either automating conventional...

BACKGROUND The purpose of vascular clamping during the course of liver resection is to reduce bleeding and subsequent complications. AIM To show both step-by-step surgical techniques for vascular exclusion of the liver and their indications. METHODS It is described the following techniques: clamping of the hepatic pedicle, "Pringle" maneuver; intermittent clamping of the hepatic pedicle; in...
