Effect of the Phosphorous Content and synthesis method on the in vitro bioactivity and mechanical properties of calcium aluminate cements
Ceramics International, 2017Co-Authors: B.a. Sánchez-escobedo, J.c. Escobedo-bocardo, Dora A. Cortés-hernández, J.m. Almanza-robles, G. García-ÁlvarezAbstract:Abstract The effect of the synthesis method and the Phosphorous Content on the in vitro bioactivity, compressive strength and setting time of Phosphorous-containing calcium monoaluminate cements (CACs) was studied. In order to obtain pure monoclinic calcium aluminate (CA), two methods were used: Pechini and solid state reaction, incorporating the Phosphorous to CA during synthesis. After 7 days of immersion in a simulated body fluid (SBF), a Ca-P rich compound was formed on the surface of all the CACs. The amount of this compound was increased as Phosphorous Content and immersion time were increased and its morphology was finer for the CACs obtained from CAs synthetized by Pechini method. Phosphorous-containing CACs showed a higher compressive strength than those with no P after 21 days of immersion in SBF. Final compressive strength of CACs elaborated with CA synthetized by solid state reaction was higher than that of CACs elaborated with CA synthetized by Pechini method due to the smaller particles obtained by this advanced method which promote a rapid hydration. Setting times decreased as Phosphorous Content was increased, being shorter in cements elaborated with CA synthetized by Pechini method due to the smaller particle size which has a strong effect on the hydration kinetics.

selective extraction of polar lipids of mango kernel using supercritical carbon dioxide sc co2 extraction process optimization of extract yield Phosphorous Content and economic evaluation
Chemosphere, 2020Co-Authors: Aparna Kayathi, Prodosh Prasad Chakrabarti, Lucas Bonfimrocha, Lucio Cardozofilho, Veeriah JegatheesanAbstract:Abstract Lipids are biomolecules extracted from plant sources and plant residues and have a beneficial role in various food, nutrition and medical applications. Supercritical carbon-dioxide as an advanced high-pressure technology which increases the productivity and has negligible environmental impact is employed for the selective extraction of polar lipids from the lipid matrix in mango kernel for the first time. The process parameters affecting the extraction such as pressure, temperature and the flow rate of CO2 are ranged in the intervals of 30–50 MPa, 40–60 °C and 10–30 g min-1, respectively. Optimization using Box Behnken design obtained the highest yield of 3.38% at 40 °C, 50 MPa and 30 g min-1. The Phosphorous Content was evaluated to understand the behaviour of polar lipids extraction at higher pressures. The study showed the effect of process parameters having significant influence on polarity and solvating capacity of CO2 which enabled for the extraction of polar lipids adding value to the mango kernel converting waste into valuable industrial products. The economic evaluation estimates the return on investment of a plant processing 3000 tons of mango kernel per year to account net present value (NPV) almost five times higher than the investment expenses and the payback period is under 4 years.

the effect of shrimp waste hydrolysate on broiler s tibia weight calcium and Phosphorous Content
Pakistan Journal of Nutrition, 2012Co-Authors: Maria Endo MahatAbstract:An experiment was conducted with 80 unsexed broilers of Arbor Acress CP 707 strain to determine the effect of shrimp waste hydrolysate on tibia bone weight, calcium and phosphorus Content. This study involved a Completely Randomized Design (CRD) with 4 treatments (0, 4, 8 and 12% of shrimp waste hydrolysate) and 5 replicates for each treatment. Diets were isonitrogenous (22% of crude protein) and isocaloric (2900 kcal/kg diet). Measured variables were weight of tibia bone, calcium and phosphorus Content of tibia bone. Data were analyzed by analysis of variance for CRD. Result shown that increasing of shrimp waste hydrolysate levels in diet had no effect (p>0.05) on tibia bone weight and calcium Content, but decreasing of Phosphorous Content (p<0.01). In conclusion, the utilization of shrimp waste hydrolysate up to 12% in broiler diet had no affected on weight and calcium of tibia bone but decreased Phosphorous Content.
