Effect of welding parameters in flux core arc welding (FCAW) with conventional and pulsed current in the efficiency and fusion rate of melting coating

This study was conducted over the welding parameters associated with three levels of pulse to lead to important data for the deposition of metal on martensitic stainless steel, through tubular electrode EC410NiMo MC – ESAB by the conventional and pulsed flux core arc welding (FCAW) process in SAE 1020 steel. Were applied three current levels, 170A, 200A e 230A with welding speed of 300 mm/s, 350 mm/s and 400 mm/s,...

Queue size comparison for standard transmission control protocol variants over high-speed traffics in long term evolution advanced (LTE-A) network

The employment of the existing protocols such as Transmission Control Protocol (TCP) cannot achieve the requirements of high-speed networks such as long term evolution advanced (LTE-A) due to the large-bandwidth and low-latency links used in this network. LTE-A network is the continuation of 3GPP-LTE (3GPP: 3rd Generation Partnership Project) and it is targeted to advanced development of the requirements of LTE in terms...

Lipoxygenase assay and cutaneous erythema test have discovered a potent anti-inflammatory activity shown by some genus Prunus plants

Medicinal plants have gained considerable interest in treatment of various medical conditions including inflammation. Rosaceae (the rose family) family of flowering plants having largest genus Prunus (plums, peaches, cherries and almonds) is one of the most economically important families.  In current study, anti-inflammatory activities of three fruit species Prunus persica, Prunus avium...
