Rare diseases affect a small part of the population, and the most affected are children. Because of the low availability of patients for testing, the pharmaceutical industry cannot develop drugs for the diagnosis of many of these orphan diseases. In this sense, the use of benzothiazole compounds that are highly selective and can act as spectroscopy probes, especially the compound 2-(4′-aminophenyl)benzothiazole (ABT), has been highlighted. This article reports the design of potential contrast agents based on ABT and iron to develop a new material with an efficient mechanism to raise the relaxation rate, facilitating diagnosis. The ABT/δ-FeOOH hybrid material was prepared by grafting (N-(4’-aminophenyl) benzothiazole-2-bromoacetamide) on the surface of the iron oxyhydroxide particles. FTIR spectra confirmed the material formations of the hybrid material ABT/δ-FeOOH. SEM analysis checked the covering of nanoflakes’ surfaces in relation to the morphology of the samples. The theoretical calculations test a better binding mode of compound with iron oxyhydroxide. Theoretical findings show the radical capture mechanism in the stabilization of this new material. In this context, Fe3+ ions are an electron acceptor from the organic phase. 相似文献

Chicken litter (CL) is a waste generated by poultry farming and it that has increased significantly in recent years. Due to chicken litter levels of nitrogen, potassium, phosphorus, and other nutrients, the CL has a potential use as fertilizer, nevertheless, this purpose has been threatened by the pollution of water resources owing to the leaching and disposal of these nutrients. The production of CL granular organomineral fertilizers (OMF) is one way of minimizing these problems and to add value to poultry waste. Thus, this study evaluates the potential of the use of different binder materials on the improvement of the hardness and nutrient release. For this, five ceramic materials were added in four different concentrations to the powder mixture containing Monoammonium Phosphate (MAP) and CL. The fertilizers were granulated and through hardness evaluation, it was possible to observe that the positive effect on the hardness depended on the additive used and its concentration. The most promising additive was magnesium oxide that, was able to improve the strength of by up to four times, when compared to the OMF control. The results shown that the nutrient release is not affected with addition different binder materials. 相似文献

Matrix multiplication is a key primitive in block matrix algorithms such as those found in LAPACK. We present results from our study of matrix multiplication algorithms on the Intel Touchstone Delta, a distributed memory message-passing architecture with a two-dimensional mesh topology. We analyze and compare three algorithms and obtain an implementation, BiMMeR, that uses communication primitives highly suited to the Delta and exploits the single node assembly-coded matrix multiplication. Our algorithm is completely general, i.e. able to deal with various data layouts as well as arbitrary mesh aspect ratios and matrix dimensions, and has achieved parallel efficiency of 86 %, with overall peak performance in excess of 8 Gflops on 256 nodes for an 8800 × 8800 matrix. We describe BiMMeR's design and implementation and present performance results that demonstrate scalability and robust behavior over varying mesh topologies. 相似文献
