The aim of this study is to investigate the feasibility of using waste bricks powder of Gachsaran Company in concrete. Cement is replaced by waste bricks powder in different proportions until 40 percent by weight. pozzolanic properties of bricks powder and compressive strength of concrete were investigated. The results demonstrated that the bricks powder show pozzolanic properties. Results also...

Background: Replacement of the gluten is one of the challenging issues in the food industry, since producing nutritious and functionally acceptable gluten-free foods is difficult. The cake is a cereal-based product that attracts the consumers due to its various flavors, long shelf-life, and relatively low cost. Considering the competition in markets and the increased demand for functional and n...

PURPOSE The micronization using milling process to enhance dissolution rate is extremely inefficient due to a high energy input, and disruptions in the crystal lattice which can cause physical or chemical instability. Therefore, the aim of the present study is to use in situ micronization process through pH change method to produce micron-size gliclazide particles for fast dissolution hence bet...

Bioaccessibility in vitro tests measure the solubility of materials in surrogate biofluids. However, the lack of uniform methods and the effects of variable test parameters on material solubility limit interpretation. One aim of this study was to measure and compare bioaccessibility of selected economically important alloys and metals in surrogate physiologically based biofluids representing or...

in this study, shelf life properties of tomato powder under effect of air drying temperature were studied. the qualitative determination was observed that acceptance of color, aroma,flavor, and appearance at 70oc is better, so best temperature was 70oc for producing of tomato powder. tomato powder after drying ,were stored into three kind of packaging including thin cellophane, thick cellophane...

Thermal properties—such as thermal conductivity, thermal diffusivity, and specific heat—of metal (copper, zinc, iron, and bronze) powder-filled high-density polyethylene composites are investigated experimentally in the range of filler content 0–24% by volume. Experimental results show a region of low particle content, 0–16% by volume, where the particles are distributed homogeneously in the po...

peripheral nerve injuries (pni) can lead to lifetime loss of function and disfigurement. different methods such as conventional allograft procedures and using of biological tubes have problems for damaged peripheral nerves reconstruction. designed scaffolds with natural and synthetic materials are now widely used in the reconstruction of damaged tissues. utilization of absorbable and non-absorb...
