A demonstration of Fluidized Bed Steam Reforming (FBSR) was recently completed on a Hanford Low Activity Waste (LAW) simulant. This technology produced stable mineral phases (feldspathoids) when co-fired with clay. The mineral phases are cage structured and were determined to retain anions such as SO4 as well as cations such as Re (simulant for Tc) in the mineral cages. The mineral phases are p...

One of the effective steps in use of water resources is accurate estimation of plants water requirement. Lack of accurate estimation of this amount leads to water loss and failure to achieve optimum yield, reduced potential of production, soil resources degradation by too much irrigation or lack of enough leaching and salinization of soils by irrigation less than necessary level, which would ul...

Vitamin and mineral deficiencies may perpetuate fibromyalgia syndrome (FMS) and chronic myofascial syndrome symptoms. Vitamin D supports healthy bone renewal, promotes normal cell growth and is a key factor in the maintenance of a healthy immune system. Moreover, low blood levels of Vitamin D are associated with pain and muscle weakness. Indeed new research released by the American Society of A...

Intermittent parathyroid hormone administration (iPTH) increases bone mass and strength by stimulating osteoblast number and activity. PTH exerts its anabolic effects through cAMP/protein kinase A (PKA) signaling pathway in mature osteoblasts and osteocytes. Here, we show that inactivation of the p38α MAPK-encoding gene with the use of an osteocalcin-cre transgene prevents iPTH bone anabolic ac...

Copper plays a key role in the physiology of methanotrophs. One way that these bacteria meet their high copper requirement is by the biosynthesis and release of high affinity copper binding compounds called methanobactins. Recent advances in methanobactin characterization include the first crystal structure, detailed spectroscopic analyses, and studies of metal ion specificity. Methanobactin ma...

Membrane bioreactor (MBR) is a promising alternative to conventional wastewater treatment methods. However this process is still under-used due to its high running costs. Its main power requirement comes from aeration, which is used to supply dissolved oxygen to the micro-organisms and to maintain the solids in suspension. In addition, in submerged MBRs, aeration is used for membrane cleaning. ...

Davis, J. B. (Socony Mobil Oil Co., Inc., Dallas, Tex.), V. F. Coty, and J. P. Stanley. Atmospheric nitrogen fixation by methane-oxidizing bacteria. J. Bacteriol. 88:468-472. 1964.-Methane-oxidizing bacteria capable of fixing atmospheric nitrogen were isolated from garden soil, pond mud, oil field soil, and soil exposed to natural gas, indicating a rather wide prevalence in nature. This may exp...

New European product standards now include a mandatory requirement for manufacturers to declare the temperature-dependent thermal conductivity for each insulation used in building equipments and industrial installations. For pipe insulation systems, the measurement is usually performed by a standard pipe test method, in which the value on a large temperature range is integrated to reduce temper...
