Deep drawing is the process of obtaining three-dimensional containers certain depths and shapes under pressing forces with help molds sheet materials. In this study, numerical shaping rectangular cups in angled deep dies was investigated experimentally by using finite element method (FEM). For purpose, die/blank holder surfaces have α=0°, α=3°, α=6°, α=9°, α=12° α=15° angles order to facilitate...

In this research, St37 and 316L steel sheets were welded using friction stir welding (FSW) process and effective parameters such as the rotational speed, linear speed of the tool, pin diameter, and their appropriate values were studied. The microstructure, hardness, and strength of the different welding regions were investigated. It was observed that in the stir zone (SZ), a mechanical operatio...

BACKGROUND Postoperative gastrointestinal dysfunction (PGD) is a common complication following laparotomy under general anesthesia (GA). Abdominal distension occurs in 8-28% of surgeries within 24 h postoperatively. The present study aimed to analyze the efficacy of electroacupuncture (EA) for the prevention of PGD by applying preoperative EA stimulation of PC6 (Neiguan), ST36 (Zusanli), and ST...

BACKGROUND Information about the genotypic characteristic of Coxiella burnetii from Hungary is lacking. The aim of this study is to describe the genetic diversity of C. burnetii in Hungary and compare genotypes with those found elsewhere. A total of 12 samples: (cattle, n = 6, sheep, n = 5 and human, n = 1) collected from across Hungary were studied by a 10-loci multispacer sequence typing (MST...

Joining of stainless steel to carbon is widely used in various industries. Resistance spot welding (RSW) a suitable process for joining sheets. Due the complexity and importance optimizing parameters, numerical simulation this was considered. In research, electrical-thermal-mechanical RSW 304 St37 performed using finite element method (FEM). Then, simulated weld nugget size compared with experi...

BACKGROUND Previous research has shown that electro-acupuncture (EA) may be effective for functional constipation. We report a protocol for a randomized controlled trial using EA to confirm the efficacy and safety for severe chronic functional constipation. METHODS/DESIGN This is a randomized, controlled trial. A total of 1,034 patients will be randomly allocated into the EA group (n=517) and...

Visceral hypersensitivity is enhanced in irritable bowel syndrome (IBS) patients. Treatment of IBS visceral pain by moxibustion methods has a long history and rich clinical experience. In the clinic, moxibustion on the Tianshu (ST25) and Shangjuxu (ST37) acupoints can effectively treat bowel disease with visceral pain and diarrhea symptoms. To investigate the regulatory function of moxibustion ...
