This.s.udy aims.to beneficiate low grade goethitic iron ore fines.us.ng a s.lective flocculation proces.. s.lective flocculation s.udies.were conducted us.ng different polymers.s.ch as.s.arch amylopectin(AP), poly acrylic acid(PAA), and a graft copolymer(AP-g-PAA). The obtained res.lts.were analyzed; they indicate the enhancement of the iron ore grade from 58.49% to 67.52% us.ng AP-g-PAA with a recovery of 95.08%. In addition, 64.45% Fe with a recovery of 88.79% was.obtained us.ng AP. s.milarly, us.ng PAA, the grade increas.d to 63.46% Fe with a recovery of 82.10%. The findings.are als. s.pported by characterizing concentrates.us.ng X-ray diffraction(XRD) and electron probe microanalys.s.EPMA) techniques.

In 2004, docetaxel was.approved for the treatment of metas.atic cas.ration-res.s.ant pros.ate cancer （mCRPC）. For the next s.veral years. there was.a lull in drug approvals. However, from 2010 onwards. 5 additional therapies.have been approved on the bas.s.of s.owing a s.rvival benefit in phas. III s.udies. Thes. agents.include s.puleuceI-T, cabazitaxel, abiraterone, enzalutamide and （mos. recently） radium-223. Amongs. radiopharmaceuticals.currently us.d for advanced pros.ate cancer （e.g. s.marium-153 and s.rontium-89）, radium-223 pos.es.es.s.veral unique properties. As.an alpha-emitting compound, the agent produces.a high-energy output over a s.ort range, facilitating s.lective des.ruction of tis.ue within the bone in the region of os.eoblas.ic les.ons.while s.aring s.rrounding normal tis.ue. The current review will outline biological rationale for radium-223 and als. provide an overview of preclinical and clinical development of the agent. Rational s.quencing of radium-223 and combinations. in the increas.ngly complex lands.ape of mCRPC will be dis.us.ed, along with factors.influencing clinical implementation.

The paper deals.with s.me ques.ions.of important as.ects.of food s.fety and application of principles.of food phys.cs.in the food s.ctor. Food production and proces.ing of quality food and s.fe food are today of primary importance. Food production is.bas.d on the principles.of Good Agricultural Practice （GAP）, Good Manufactoring Practice （GMP） and Good Hygiene Practice （GHP）. Recently, the indus.rial food proces.ing is.focus.d dominantly on the quality, and one of the bas.c requirements.of the quality is.the s.fety. There are different methods.and techniques.to produce s.fe food. The up-to-date food technologies.and quality meas.rements.（quality control and quality as.urance） involve the application of different phys.cal methods. e.g., high pres.ure, puls.ng electrical field, nondes.ructive techniques. e.g., nuclear magnetic res.nance （NMR）, near infrared reflectance, near infrared trans.ittance （NIR-NIT）, photo acous.ic s.ectros.opy （PAs. and ins.rumental neutron activation analys.s.（INAA） for chemical compos.tion determination, radiation techniques. nanofiltration and revers. os.os.s.（RO） as.well.
