The carburization process is a surface hardening where carbon added to the without changing core properties of material. This carried out at austenite temperature so that can diffuse into phase. only be done on low steels with content below 0.25%. research was conducted ST37 steel, which steel 0.18% content. type hardened carburizing 850 C long lasting time 1 hour, then it under moderate coolin...

Several factors must be considered when designing parts that are being made by bending. The primary factor is minimum radius and angle of bending that can be bent successfully without metal cracking. Low carbon steel metal (st37), manufactured by Libyan Iron and steel Company, was used in this study. Various bending processes by Vee die for different radii and calculate thickness were conducted...

BACKGROUND Electroacupuncture (EA) is used clinically for the treatment of constipation. Serotonin (5-hydroxytryptamine, 5-HT) plays an important role in colonic motility; however it is unknown whether alterations in colonic 5-HT are associated with EA. In this study, the effect and mechanism of EA at acupuncture points LI11 and ST37 were examined using a cold saline-induced rat model of consti...

nowadays, in order to reach minimum production cost in machining operations, various optimization methods have been proposed. since turning operation has different parameters affecting the workpiece quality, it was selected as a complicated manufacturing method in this paper. to reach sufficient quality, all influencing parameters such as cutting speed, federate, depth of cut and tool rake angl...

Background. The roles of the sympathetic and parasympathetic systems in mediating the effect of electroacupuncture (EA) at ST37 on jejunal motility have yet to be demonstrated. Aim. We used rats and mice to investigate the effect and mechanism of action of EA at ST37 on jejunal motility. Methods. Jejunal motility was recorded by a balloon placed in the jejunum and connected to a biological sign...

We investigated the effect of welding parameters on ultimate tensile strength of structural steel, ST37-2, welded by Metal Active Gas welding. A fractional factorial design was used for determining the significance of six parameters: wire feed rate, welding voltage, welding speed, travel angle, tip-to-work distance, and shielded gas flow rate. A regression model to predict ultimate tensile stre...

Our previous study showed that mossy fiber sprouting can occur in the hippocampus region in rats 6 wk after kainic acid-induced epileptic seizure, and this mossy fiber sprouting can facilitate epileptogenesis. Transcutaneous auricular vagal nerve stimulation (VNS), which is similar to cervical VNS, can reduce the occurrence of epileptic seizure in intractable epilepsy patients. Greater parasymp...

Friction welding is a type of solid state where the process carried out in phase to combine various types ferrous and non-ferrous metals that cannot be welded by fusion method but for different results are less than optimal due cracks on surface differences mechanical properties cause result brittle, therefore an interlayer used. In this study, observations were made joint friction using dissim...
