A field experiment was conducted on a sandy loam soil at an Experimental Farm in taejon, South Korea, to determine the effects of paper mill sludge compost application rates on K, Na, Ca and Mg concentrations of soybean (Glycine max (L.) Merr.) aboveground tissues and the genotypic effects on the concentrations of these elements. Sludge compost treatments of 0, 75, and 150 t ha-1 were applied to 30 diverse soybean cultivars. Concentrations of K, Na, Ca, and Mg in aboveground tissues harvested 69 days after …

the magnetic strength and versatility of heterostructures generated via a simple microemulsion cluster-formation technique is demonstrated. this approach allows optimization of individual component magnetic nanoparticles prior to heterostructuring, expediting the discovery and optimization of hybrid magnetic materials. the efficacy of this method is validated through a magnetic study of nanoparticle clusters combining antiferromagnetic CoO and superparamagnetic CoFe204 nanoparticles with tunable particle ratio and size. An enhancement of coercivity compared with pure CoFe204 nanoparticles indicates that close interparticle contacts are achieved. Upon annealing, an exchange bias field of 0.32 t was observed--over twice that achieved in any other colloidally-synthesized system. Additionally, the unique microstructure is defined during cluster formation and thus protects magnetic coercivity during the annealing process. Overall, this work demonstrates a general approach for quickly exploring magnetic parameter space, designing interparticle functionality, and working towards the construction of high-value bulk magnets with low materials and processing cost.

this paper provides an convergence analysis of a fractional-step projection method for the controlled-source electromagnetic induction problems in heterogenous electrically conducting media by means of finite element approximations. Error estimates in finite time are given. And it is verified that provided the time step τ is sufficiently small, the proposed algorithm yields for finite time t an error of O(h^s + τ) in the L^2-norm for the magnetic field h, where h is the mesh size and 1/2 < s <_ 1.

Zinc-indium-tin oxide (ZItO) films were grown by pulsed-laser deposition. three different material compositions were investigated: ZItO-30, ZItO-50 and ZItO-70 in which 30%, 50% and 70%, respectively, of the indium in the In 2 O 3 structure was replaced by substitution with zinc and tin in equal molar proportions (co-substitution): In 2 2x Zn x Sn x O 3 , where x 0.3, 0.5, 0.7. All ZItO films grown at room temperature were amorphous. the first evidence of crystallinity was observed at higher deposition-temperature as the degree of co-substitution was increased. A decrease in mobility and conductivity was also observed as the degree of co-substitution was increased. the highest mobility for ZItO-30 and ZItO-50 was observed at deposition temperatures just prior to crystallization. the effect of deposition temperature on carrier concentration was minor compared to the effect of oxygen partial pressure during deposition.

Meniscus injuries are extremely common with approximately one million patients undergoing surgical treatment annually in the U.S. alone, but no regenerative therapy exist. Previously, we showed that controlled applications of connective tissue growth factor (CtGF) and transforming growth factor beta 3 (tGFβ3) via fibrin-based bio-glue facilitate meniscus healing by inducing recruitment and stepwise differentiation of synovial mesenchymal stem/progenitor cells. here, we first explored the potential of genipin, a natural crosslinker, to enhance fibrin-based glue’s mechanical and degradation properties. In parallel, we identified the harmful effects of lubricin on meniscus healing and investigated the mechanism of lubricin deposition on the injured meniscus surface. We found that the pre-deposition of hyaluronic acid (hA) on the torn meniscus surface mediates lubricin deposition. then we implemented chemical modifications with heparin conjugation and CD44 on our bioactive glue to achieve strong initial bonding and integration of lubricin pre-coated meniscal tissues. Our data suggested that heparin conjugation significantly enhances lubricin-coated meniscal tissues. Similarly, CD44, exhibiting a strong binding affinity to lubricin and hyaluronic acid (hA), further improved the integrated healing of hA/lubricin pre-coated meniscus injuries. these findings may represent an important foundation for developing a translational bio-active glue guiding the regenerative healing of meniscus injuries.

tcells are one of the most migratory cells in the body. the development and function of t cells depend on their interaction with other cells, which is, in turn, dependent on optimal cell migra- tion. t cells migrate largely in three dif- ferent ways： rapid distribution via blood vessels through hemodynamic move- ment, transendothelial migration and interstitial movement. transendothelial migration involves sequential activation of selectins, chemokine receptors and integrin molecules expressed by migrat- ing t cells, leading to extravasation from blood vessel into local tissue environ- ments.
