In winter wheat, grain development is asynchronous. The grain number and grain weight vary significantly at different spikelet and grain positions among wheat cultivars grown at different plant densities. In this study, two winter wheat (Triticum aestivum L.) cultivars, 'Wennong6' and 'Jimai20', were grown under four different plant densities for two seasons, in order to study the effect of pla...

This chapter deals with breeding aspects of one of the most important crops for food security in the world. Initially it shows how diverse rice is with 22 species, different levels of ploidy and six diversity groups. The choice of parents for crossing, when having such wide genetic diversity available, requires careful characterization and evaluation of the germplasm as well as good knowledge a...

With rapid and continuous population growth and the associated declining quality of cultivated land, food security in China has been attracting the attention of scholars both domestically and internationally. In recent decades, the implications of the cultivated land balance policy have promoted spatial changes of cultivated land. Estimating the agricultural potential productivity and assessing...

Advances in pervasive system are rapidly taking us to a novel frontier in security, revealing a whole new landscape of threats. In open and dynamic environments, malicious terminals may enter a network without being detected, and various malwares may invisibly install themselves on a device. While roaming between heterogeneous networks which are adjusted for their own protection requirements, a...

Individual grain weight is a major yield component in wheat. To provide a comprehensive understanding of grain weight determination, the carpel size at anthesis, grain dry matter accumulation, grain water uptake and loss, grain morphological expansion, and final grain weight at different positions within spikelets were investigated in a recombinant inbred line mapping population of bread wheat ...

Memory integrity protection has been a longstanding issue in trusted system design. Most viruses and malware attack the system by modifying data that they are not authorized to access. With the development of the Internet, viruses and malware spread much faster than ever before. In this setting, protecting the memory becomes increasingly important. However, it is a hard problem to protect the d...

Enterprise networks are in constant danger of being breached by cyber-attackers, but making the decision about what security tools to deploy to mitigate this risk requires carefully designed evaluation of security products. One of the most important metrics for a protection product is how well it is able to stop malware, specifically on “zero”-day malware that has not been seen by the security ...

High-resolution electron backscatter diffraction (EBSD) was used to examine the grain structure in long rods of ultrafine-grain (UFG) commercial-purity titanium produced for medical implants. The UFG material was obtained by equal channel angular pressing (ECAP) using a Conform scheme followed by rod drawing. The microstructure was found to be bimodal consisting of relatively coarse elongated g...

This paper summarises six studies undertaken by the Sheep CRC to elucidate certain aspects of confinement feeding of sheep. A review of confinement feeding highlighted the variability of growth rate and feed conversion of sheep and revealed that little is known about the use of sorghum for feeding sheep. The review indicated that the main factors responsible for variation of growth rate and fee...

While fulfilling the food demand of an increasing population remains a major global concern, more than one-third of food is lost or wasted in postharvest operations. Reducing the postharvest losses, especially in developing countries, could be a sustainable solution to increase food availability, reduce pressure on natural resources, eliminate hunger and improve farmers' livelihoods. Cereal gra...
