In this study the characteristics of two different kinds of La0.6Sr0.4Co0.2Fe0.8O3 (LSCF) powders, one in-house synthesized powder by a co-precipitation method and another one purchased from Fuel Cell Materials Co. (FCM Co., USA), were compared. The co-precipitated powder was prepared by using ammonium carbonate as precipitant with a NH4+/NO3- molar ratio of 2 and calcination at 1000C for 1 h....

In the current work, high density polyethylene (HDPE) composites were fabricated via Friction Stir Processing (FSP). A two-phase Fe-Fe3O4 powder was used as reinforcing agents. The extremely low cost obtained from shot-blasting of as-forged carbon steel components. X-ray diffraction (XRD) to phase analysis and evaluation purity as-received powder. size distribution determined by Laser Particle ...

Large number of schemes have been proposed to deal with location privacy preservation in VANETs. One the most popular ways preserve is pseudonym changing, which includes mix-zone, silent zone, mix-context zone and trigger-based schemes. The pseudonyms must be changed after a specific interval privacy. All these require vehicles part dense traffic order change pseudonym. Although changing are no...

As a by-product generated from the processing of corn, the production in China of corncob (CC) is abundant, with up to 3.87 million tons per year. The biomass gasification industries make use of the CC residue as feedstock, but large volumes of generated corncob ash (CCA) requires daily disposal. In this study, CCA was characterized by laser particle size analyzer (LPSA), X-ray fluorescence (XR...

4 years old boy presented with prolonged fever for 12 weeks not responding to treatment with antibiotic and antipyretics along with pain, swelling and limitation of movements affecting both ankles, right knee and cervical joints. Erythematous skin rash was there. He had faint systolic murmur at LPSA. Abdominal examination revealed liver palpable 2 cm below costal margin. After one week of hospi...
