This study aimed to analyze BKI Grade (KI-A) plate material using the pre-heat process determine tensile strength and hardness. The method involved welding with shielded metal arc (SMAW) type. variations used several temperatures, such as 50⁰C, 120⁰C, 220⁰C, without heat treatment. obtained specimen pre-heating had lowest of 442.64 MPa, 220⁰C highest average 450.11 MPa. result showed that was p...

Heat Transfer has special importance in engineering applications. So, researchers have suggested different new idea to increase heat transfer and using nanofluid is one of these methods In recent years, new methods have been used. One of these methods is the use of nanofluids, ., because nanofluids have higher heat transfer potential than base conventional fluids. In this investigation effect o...

Using elegant experiments, Ito et al. (2011) were able to demonstrate that a siRNA pathway is crucial to prevent transgenerational retrotransposition in plants subjected to heat-stress (Ito et al., 2011). The heat-stress treatment consisted of a double-temperature-shift stress: 24 h at 6°C followed by 24 h at 37°C. The transcription of a particular family of Ty1/copia-type retrotransposons, nam...

Objective- To evaluate antinociceptive efficacy of pre- versus post-incisional morphine, tramadol and meloxicam using tail-flick test in an incisional model of pain in rats. Design- Prospective, randomized experimental study. Animals- Eighty, adult, male Wistar rats weighing 250–300 g. Procedures- Animals were randomly divided into eight groups to receive pre- or post-incisional (tail skin i...

dissimilar metals friction welding of austenitic–martensitic stainless steels is commonly used in order to manufacture engine valves in the automobile industry. in this study, x53crmnnin219 (austenitic stainless steel) and x45crsi93 (martensitic stainless steel) valve steel rods were welded by friction welding process. the welded joint was then heat treated at 760 0c for 60 min. mechanical prop...
