Biofortification with selenium and lithium improves nutraceutical properties of major winery grapes in the Midwestern United States

Enriching the micronutrients, selenium (Se) and lithium (Li), in grapes to improve their nutraceutical properties were implemented by foliar application of organic fertiliser rich in Se and Li onto five grape cultivars. The effects of this biofortification on vine vigour, fruit quality, overall micronutrients and phenolic compounds also were investigated. Agronomic biofortification was found greatly increased the Se and Li content in the whole grape by multiple times, meanwhile it did not significantly affect the vine vigour and fruit quality of grapes. However, the biofortification did impact the Ionome (including all the mineral nutrients and trace elements) and phenolic compounds in grapes and this varied among cultivars. This study demonstrated foliar spray of organic Se/Li fertiliser was a very effective strategy to biofortify these micronutrients in grape berries, particularly in the skin, and therefore might be a promising strategy to increase the consumption and awareness of these grapes.

基于mini C RAN的IEEE1588时间同步方案

基于通用处理平台的室内覆盖基站系统(mini C-RAN)是一种基于通用处理器研发的小型化、低功耗、高容量蜂窝覆盖的TD-LTE基站系统.由于TD-LTE系统对时间同步要求非常高,所以提出一种基于mini C-RAN的1588时间同步方案.在基带池内部采用主从同步模型使其内部达到时间同步并向下级传输1588时间同步报文,在交换机内部采用透明时钟模型得到1588报文在交换机内部的传输时延.通过用1588时间分析仪测试其时间延迟在正负200 ns内,达到了TD-LTE基站系统要求.     

燃煤过程中水蒸气对砷释放特性的影响

为了研究水蒸气对煤燃烧过程中砷释放特性的影响,在800~1 300℃下对庆华煤进行燃烧试验,并结合XRD分析了水蒸气对砷释放的作用机理。气氛中有水蒸气时,可以明显加快煤的失重;相同温度下,气氛中存在水蒸气时,煤中砷的逃逸有一定的增加,随着水蒸气浓度的增加,逃逸率增加趋势放缓;随着温度的增加,水蒸气对砷的逃逸率的提升效果减弱。在水蒸气气氛下灰的矿物质组成结构发生变化,石膏等硫酸盐增多,主要是水蒸气促进了石膏的形成,缩减了高活性CaO的停留时间,抑制了CaO对砷的捕捉,造成砷吸附率降低,逃逸率增加。

Modeling Method of Automotive Body CAN/LIN Nets Application Protocol Based on Object-oriented Colored Petri Net

Recently automotive nets are adopted to solve increasing problems in automotive electronic systems.Technologies of automotive local area network from CAN and LIN can solve the problems of the increasing of wire bunch weight and lack in module installation space.However,the multilayer automotive nets software becomes more and more complex,and the development expense is difficult to predict and to keep in check.In this paper,the modeling method of hierarchical automotive nets and the substitution operation based on object-oriented colored Petri net(OOCPN) are proposed.The OOCPN model which analyzes the software structure and validates the collision mechanism of CAN/LIN bus can speed the automobile system development.First,the subsystems are divided and modeled by object-oriented Petri net(OOPN).According to the sets of message sharing relations,the message ports among them are set and the communication gate transitions are defined.Second,the OOPN model is substituted step by step until the inner objects in the automotive body control modules(BCM) are indivisible and colored by colored Petri net(CPN).And the color subsets mark the node messages for the collision mechanism.Third,the OOCPN model of the automotive body CAN/LIN nets is assembled,which keeps the message sets and the system can be expanded.The proposed model is used to analyze features of information sharing among the objects,and it is also used to describe each subsystem real-time behavior of processing messages and implemental device controllers operating,and puts forward a reasonable software framework for the automotive body control subsystem.The research can help to design the communication model in the automotive body system effectively and provide a convenient and rapid way for developing the logical hierarchy software.
