Tailings are one of the largest solid wastes in stock at present. In order to improve comprehensive utilization rate tailings, especially solve problems fine-grained tailings treatment, concrete composite admixture was prepared by using iron powder and slag powder. study influence on workability long-term mechanical properties concrete, C30 C50 with different dosages were prepared, slump, expan...

Ceramic micro-stereolithography (mSL) was recently introduced in the fabrication of complex 3D ceramic microstructures. Light scattering is found as an important factor in the mSL of ceramics. In this work, the Monte Carlo ray tracing method is employed to investigate the in¯uences of the important materials properties on the scattering during the ceramic mSL. It is found that the scattering is...

In order to improve the mechanical and biological properties of calcium phosphate cement (CPC, nanometer-biomaterial) for bone reconstruction in the rabbit femoral defect model, fibrin glue (FG, the natural product, purified from the blood) was introduced at three different ratios. The CPC powder and the FG solution were mixed, respectively, at the powder/liquid (P/L) ratios (g/mL) of 1:1, 3:1,...

STUDY OBJECTIVES To evaluate the efficiency and reproducibility of pulmonary delivery of an investigational tobramycin PulmoSphere formulation (PStob) [Inhale Therapeutic Systems; San Carlos, CA] by a passive dry powder inhaler, and to compare serum concentrations and whole-lung deposition with a commercial nebulized tobramycin product (TOBI; Chiron Corporation; Seattle, WA). DESIGN A five-pe...

Sing, K.W., Sofian-Azirun, M. and Tayyab, S. 2012. Protein analysis of Chrysomya megacephala maggot meal. Animal Nutrition and Feed Technology, 12: 35-46. Protein content of Chysomya megacephala maggot meal extract was determined using different colorimetric methods such as biuret method, dye-binding method and Lowry method. Protein estimation was performed after dissolution of maggot powder in...

Graphene with ultrahigh intrinsic strength and excellent thermal physical properties has the potential to be used as the reinforcement of many kinds of composites. Here, we show that very high tensile strength can be obtained in the copper matrix composite reinforced by reduced graphene oxide (RGO) when micro-layered structure is achieved. RGO-Cu powder with micro-layered structure is fabricate...

In order to achieve a sustainable mix design, this paper evaluates self-consolidating green concrete (SCGC) properties by experimental tests and then examines the design parameters with an artificial intelligence technique. regard, cement was partially replaced in different contents granulated blast furnace slag (GBFS) powder, volcanic fly ash, micro-silica. Moreover, fresh hardened were perfor...
