基于SMP的总线式软运动控制引擎设计

提出了基于SMP实时架构的EtherMAC实时以太网主站的设计方法,开发了一种运行于内核空间的运动控制引擎,并给出了一种通过在共享内存建立内存堆栈方式的跨平台编程接口设计方法。通过设计总线抽象层将总线控制资源抽象,降低了运动控制引擎与总线之间耦合性,增强了总线系统或从站设备的可替换性。原型机进行功能验证表明,该引擎实现了较好的易用性和可移植性,并间接增强了EtherMAC的实时性能。

Bio-based Coating from Fish Gelatin,K-Carrageenan and Extract of Pomegranate Peels for Maintaining the Overall Qualities of Fish Fillet

ABSTRACT

To maintain the overall quality of fisheries products, functional edible coatings from natural ingredients including fish gelatin (Gf), k-carrageenan (Cr), and extract of pomegranate peels (PPE) were composed. The Gf was extracted from blue tilapia (Oreochromis aureus), microencapsulated with Cr, and then loaded with PPE (at concentrations of 0.5%, 1.0%, 1.5% and 2.0%). The Fourier transform infrared (FTIR) spectra of Gf/Cr composites verified their cross-linkage and functionality; the Gf/Cr microcapsules had a mean particle size of 36.2 µm with good distribution and homogeneity. The coating of Nile tilapia (Oreochromis niloticus) fillets, with constructed solutions from Gf/Cr/PPE, revealed their positive effects on fillet quality attributes; the effectiveness was dependent on the supplemented PPE concentration. The Gf/Cr/PPE solutions could effectively reduce the microbial counts of total aerobics, psychrotrophs, yeast and molds, and enterobacteriaceae groups throughout 30 days of refrigerated storage. Additionally, the analysis of spoilage chemical parameters (total volatile basic nitrogen, peroxide value, and thiobarbituric acid reactive substances) in coated samples indicated that formulated solutions could hinder the increase of their values during storage. The sensorial evaluation indicated the acceptability and validity of coated samples for up to 30 days of storage. Gf/Cr/PPE coating is recommended for overall quality maintenance of fish fillets and prolongation of storage using safe and healthy biopreservatives.

Effects of Plant and Soil Factors on Growth of Young Apple and Blackcurrant Plants

Abstract

Shoot growth as affected by plant size at planting, peat application in the planting hole, pruning, drip-irrigation and, for apple, specific apple replant disease (SARD) was investigated in apple (cv. Elstar) and blackcurrant (cvs Ben Lomond and Ben Nevis), using a multifactorial design. In the first year after planting, peat application and drip-irrigation enhanced shoot growth in both species, with a further interactional increase when both treatments were applied. The extension growth of apple, in contrast to blackcurrant, was positively related to plant size, and the strength of the relationship was distinctly improved when growth conditions were good. Pruning had only small effects on total shoot growth, with a trend towards an increase when growth conditions were poor.
