Rare Earth Element Recovery from Phosphogypsum using a Biolixiviant

This project describes the process of recovering of rare earth elements (REE) from phosphogypsum (PG) waste using a novel biolixviant produced by a bacteria strain known as Glucanobacter oxydans and is inspired by novel research occurring at Idaho National Laboratories. This report details design of a plant which has the capacity to produce the biolixiviant through fermentation, use this biolixiviant to leach REE from a solid waste such as PG, and recover the REE in oxide form through crystallization, filtration, and subsequent high temperature decomposition. The plant has the capability of processing nearly 1 million MT of PG a year and yields 286,000 kg of a rare earth oxide (REO) mixture, valued at approximately $9 per kg. As it stands, this process is unprofitable: it has a negative internal rate of return after 15 years of production and has a NPV of negative$147,664,900. In its third year of production, operating at 91% capacity, the plant has a -21.17% ROI. An alternative design is considered where fermentation is cut and H2SO4 is the lixiviant, removing 79% of the original capital necessary to create the plant. Though still negative, the IRR/ROI are much more sensitive to changes in product price, thus opening a potential path to profitability in the near future as prices are expected to increase

Prion decontamination method

Autoklaviranje je metoda najčešće primjenjivana za dekontaminaciju priona, sama ili u kombinaciji s NaOH ili drugim kemijskim reagencijama. Naša metoda autoklaviranja u 0,1N NaOH pri temperaturi od 134 °C, kroz 18 minuta je neškodljiva za instrumente i okolinu, pouzdanija od prijedloga Svjetske Zdravstvene Organizacije (bez NaOH ) koja se danas primjenjuje u većini evropskih zemalja (Velika Britanija 1986., Švicarska 2003.). Naša metoda je jednostavno izvediva a troškovi dekontaminacije su mali. Uspjeh je ovisan o postupku s instrumentima neposredno nakon uporabe, da bi se spriječilo sušenje; osušene instrumente više nije moguće dekontaminirati. Tako se danas radi u većini bolnica na svijetu, a moguće je to izbjeći uranjanjem instrumenata neposredno nakon uporabe u autoklavabilne posude iz polipropilena (pp) u kojima je 0,1N NaOH (ili druge kemikalije). Na kraju rada, instrumenti se ručno, prenesu u autoklav zajedno s tekućinom u koju su uronjeni. Proces autoklaviranja traje 2,5–3 sata. Na kraju se i pp posude, složene jedna u drugu, autoklaviraju na jednaki način i osuše za slijedeći radni dan.Autoclaving is the method most frequently used for the decontamination of prion infected medical devices alone or in combination with NaOH or chemicals. Our proposal is the simultaneous autoclaving in 0.1N NaOH for 18 minutes at 134 °C; it is considerably more rigorous than autoclaving in water or in porous autoclaves under identical pressure conditions as practiced in Europe (first Great Britain 1986, Swiss law 2003). It is less harmful as 1N solution and completely harmless for the environement and autoclave including the lowest costs for the hospital. Devices must immediately immersed in 0.1N NaOH (or other) contained in autoclavable polypropylene pans (pp) to avoid dessication. Dried instruments cannot be decontaminated. Instruments are then manually transferred to the autoclave (together with the fluid) to immerse instruments. Autoclaving process is for 2.5-3 hours. Finally, pans can also be autoclaved (stapled) under the same condition

Body Fat Percentage and the Long-term Risk of Fractures. The EPIC-Norfolk Prospective Population Cohort Study

Background: This cohort study aimed to determine the association between body fat percentage (BF%), incident fractures and calcaneal broadband ultrasound attenuation (BUA). Methods: Participants were drawn from the EPIC-Norfolk Prospective Population Cohort Study (median follow-up = 16.4 years). Cox models analysed the relationship between BF% and incident fractures (all and hip). Linear and restricted cubic spline (RCS) regressions modelled the relationship between BF% and BUA. Results: 14,129 participants (56.2 % women) were included. There were 1283 and 537 incident all and hip fractures respectively. The participants had a mean (standard deviation) age of 61.5 (9.0) years for women and 62.9 (9.0) years for men. Amongst men, BF% was not associated with incident all fractures. While BF% 23 % was associated with increased risk of hip fractures by up to 50 % (hazard ratio (95 % confidence interval) = 1.49 (1.06–2.12)). In women, BF% 35 % was not associated with this outcome. Higher BF% was associated with lower risk of incident hip fractures in women. Higher BF% was associated with higher BUA amongst women. Higher BF% up to ~23 % was associated with higher BUA amongst men. Conclusions: Higher BF% is associated with lower risk of fractures in women. While there was no association between BF% and all fractures in men, increasing BF% >23 % was associated with higher risk of hip fractures in men. This appears to be independent of estimated bone mineral density. Fracture prevention efforts need to consider wider physical, clinical, and environmental factors
