The uranium (234U/238U) and radium (228Ra/226Ra) activity ratios and 87Sr/86Sr isotopic ratio in thermal groundwater, subsurface water (groundwater) and river water from Poddebice and Uniejow were determined. The uranium and radium activity ratios and strontium isotopic ratio varied from 0.629 to 1.471, from 0.396 to 4.961 and from 0.708438 to 0.710344, respectively. The results for the thermal...

A series of zwitterionic hybrid membranes were prepared via the ring opening of 1,3-propanesultone with the amine groups in the chains of TMSPEDA and a subsequent sol-gel process. Their kinetic models for strontium removal were investigated using three two-parameter kinetic equations (i.e., Lagergren pseudo-first order, pseudo-second order, and Elovich models). Adsorption mechanism was evaluate...

Introduction Strontium ranelate is an agent used for the treatment of osteoporosis. It consists of two atoms of stable strontium and an organic part: ranelic acid. Simultaneously, it stimulates the formation of new bone and reduces bone resorption, resulting in a deviation from the balance of bone turnover towards formation. These actions are effected by improving the replication of pre-osteobl...

OBJECTIVE To evaluate changes in the use of strontium ranelate following a health safety warning in November 2007 on the risks of the development of DRESS (Drug Rash with Eosinophilia and Systemic Symptoms) with the use of this medicine. METHOD Monthly strontium ranelate DHD (daily defined doses/1,000 inhabitants/day) were calculated between 2006 and 2008 in a health area of Spain. The data w...

A method for total calcium in serum was optimized, a dual double-beam atomic absorption spectrophotometer being used, with strontium as an internal reference. The effect of HCI and lanthanum concentrations on the signals of both calcium and strontium was determined. The final analysis was unaffected by known sources of interference in serum at a 50-fold dilution of serum in 50mmolar HCI contain...

Atomic Layer Deposition of Platinum on Strontium Titanate Surfaces Tremendous energy savings and environmental benefits are possible from improved catalysts for chemical manufacturing and emissions reduction. Breakthroughs in catalyst development will be enabled by precise methods for synthesizing nanostructured materials. Atomic layer deposition (ALD) is a thin film growth technique that is cu...

OBJECTIVE To determine the surgical outcome of patients with axial cervical spine fractures. METHODS The randomised double-blinded placebo-controlled clinical study was conducted at the Indus Hospital, Karachi, from August 2011 to August 2013. Patients were randomised to receive placebo or strontium ranelate postoperatively after surgical fixation of tibial diaphyseal fractures. Assessment of...

p C P ydrogen sulfide, like nitric oxide, was best known as a oxic pollutant before becoming recognized as a key egulator of several physiologic processes. In recent ears, evidence has accumulated to suggest important oles for hydrogen sulfide as a mediator of several asects of gastrointestinal and liver function. Moreover, lterations in hydrogen sulfide production could contribte to disorders ...

The thermodynamics for the first electron transfer step for sulfide and oxygen indicates that the reaction is unfavorable as unstable superoxide and bisulfide radical ions would need to be produced. However, a two-electron transfer is favorable as stable S(0) and peroxide would be formed, but the partially filled orbitals in oxygen that accept electrons prevent rapid kinetics. Abiotic sulfide o...

background: in this study, ferrate (vi) and ultraviolet (uv) radiation were employed to remove hydrogen sulfide from municipal wastewater resulting in a reduction in chemical oxygen demand (cod). although ferrate (vi) and uv have been used individually for the removal of a few pollutants from urban and industrial wastewater, there exists no study to investigate the effectiveness of simultaneous...
