The potential for loss of bone mineral mass due to space flight was recognized by space scientists even before man's first venture into micro-gravity. Early life science studies in both the U.S. and Russian space programs attempted to measure the effects of reduced gravity on skeletal homeostasis, and these measurements have become more sophisticated with time. Bone-related measurements have ty...

The metal mining industry faces many large challenges in future years, among which is the increasing need to process low-grade ores as accessible higher grade ores become depleted. This is against a backdrop of increasing global demands for base and precious metals, and rare earth elements. Typically about 99% of solid material hauled to, and ground at, the land surface currently ends up as was...

Bovine milk has been shown to contain bioactive components with bone-protective properties. Earlier studies on bovine milk whey protein showed that it suppressed bone resorption in the female ovariectomised rat. A new osteotropic component was subsequently identified in the whey basic protein fraction, but bone bioactivity may also be associated with other whey fractions. In the present study, ...

The ability to collect uranium from seawater offers the potential for a nearly limitless fuel supply for nuclear energy. We evaluated the use of functionalized nanostructured sorbents for the collection and recovery of uranium from seawater. Extraction of trace minerals from seawater and brines is challenging due to the high ionic strength of seawater, low mineral concentrations, and fouling of...

The important role gained by waste incineration in European waste management systems is recently clashing with increasing concerns about loss of resources in waste, i.e. metals. Even though the recovery of valuable resources in residues from waste incineration is becoming a widespread practice, a significant portions of valuables resources remains in the ash and ends up in disposal sites. The g...

background: celiac disease (cd), as an autoimmune disease has initiated since ingestion of food containing gluten. constant intolerance to gluten causes damages of the small intestinal mucosa. one reason of mal-absorption in children and infants is cd. additionally, about 75% of newly identified patients with cd have low bone mineral density (bmd). many factors have role in metabolic bone disea...

diversification of phosphorus sources can bring substantial synergy effects within all thesustainable development domains: environmental, economic and social, and such an opportunity should not beoverlooked. urban sinks accumulate phosphorus and other elements and may serve as sources of secondaryraw materials. this paper evaluates phosphorus sources based on their total material requirement (t...

dispersive liquid liquid microextraction (dllme) combined with gas chromatography–mass spectrometry (gc–ms) was used for the extraction and determination of 13 polycyclic aromatic hydrocarbons (pahs) in mineral water samples. in this procedure, the suitable combination of extraction solvent (500 µl chloroform) and disperser solvent (1000 µl acetone) were quickly injected into the water sample (...

(2014) " Resource recovery from hazardous waste – the case of MSW incineration fly ashes " In: Proceedings " 4th International Conference Industrial and Hazardous Waste Management", 2.-5. SUMMARY: In the European Union almost 78 million tons of waste are annually combusted in Waste-to-Energy plants. Solid residues generated thereby contain altogether about 72,000 t/a of Zn, of which more than 5...

As a bioaerosol sampling standard, Andersen type impactor is widely used since its invention in 1950s, including the investigation of the anthrax attacks in the United States in 2001. However, its related problems such as impaction and desiccation stress as well as particle bounce have not been solved. Here, we improved its biological collection efficiencies by plating a mineral oil layer (100 ...
