Preparation and welding of the pressure aluminium pipes

The project is an analysis of technology production of pressure pipes made of aluminum alloys. The basis is a literary study of TIG technology, aluminum heat-tretable and non-heat-treatable materials. The flange-material is EN AW 5083 and the pipe is made of EN AW 6005A. The design of the welding is compromise between the preparation, the cleaning of the welding edges and the weld metal backing strip. Weld was made in real production. Examined impacts are evaluated on the basis of destructive and non-destructive welding test methods. After heating process of weldment material exhibits better mechanical properties. Using the economical and technological evaluation were selected sutiable proces parameters. The result is a suitable weld of the pressure vessel. Further optimization is possible through automation and robotics

Additional file 3: Figure S3. of EEG response varies with lesion location in patients with chronic stroke

Pearson’s correlation coefficients for the beta band power changes between the HCs and each of the three patient subgroups for each of the 28 channels during the MI task supination movement. Significant results of a pairwise statistical analysis on the differences in correlation coefficients are indicated (one-way ANOVA test, *p < 0.05; **p < 0.01). (JPG 640 kb

Twenty-eight channel topography of the beta band during active supination (left side) and grasping (right side) movements. The horizontal axis represents 2 s of the motor task with a 0.5-s window interval. The vertical axis represents the subject groups. The upper three rows represent each subgroup of patients according to their lesion location. The fourth row represents all patients and the last row represents healthy controls. (JPG 1727 kb

Does the Type of Anesthetic Technique Affect In-Hospital and One-Year Outcomes after Off-Pump Coronary Arterial Bypass Surgery?

<div><p>Despite numerous previous studies, there is little data on the effects of anesthetics on clinical outcome after off-pump coronary arterial bypass grafting (OPCAB). Therefore, we retrospectively compared the effects of anesthetic choice on in-hospital major adverse events (MAEs) and one-year major adverse cardiovascular and cerebral events (MACCEs) in patients undergoing OPCAB. Electronic medical records were reviewed in 192 patients who received propofol-remifenanil total intravenous anesthesia (TIVA) and propensity score-matched 662 patients who received isoflurane anesthesia. The primary endpoints were in-hospital MAEs and one-year MACCEs. The components of in-hospital MAEs were in-hospital death, myocardial infarction (MI), coronary revascularization, stroke, renal failure, prolonged mechanical ventilation longer than 72 h, and postoperative new cardiac arrhythmia requiring treatment. One-year MACCEs was defined as a composite of all-cause mortality, MI, coronary revascularization, and stroke. There was no significant difference in risk of in-hospital MAEs (OR = 1.29, 95% CI = 0.88–1.88, <i>P</i> = 0.20) or one-year MACCEs (OR = 0.81; 95% CI = 0.46–1.42, <i>P</i> = 0.46) between the groups. The risk of postoperative new arrhythmia including new atrial fibrillation significantly increased in the TIVA group compared to the isoflurane anesthesia group (OR = 1.72, 95% CI = 1.12–2.63, <i>P</i> = 0.01). In conclusion, the choice between propofol-remifentanil TIVA and isoflurane anesthesia did not show differences in incidence of in-hospital MAEs or one-year MACCEs in patients undergoing OPCAB. However, further studies on the effects of anesthetics on development of in-hospital new arrhythmia will be needed.</p></div
