Morphological characterization facilitates the seed production agencies to identify varieties on phenotypic basis by their distinguished characters. The presence of sufficient variability for various agro-morphological traits, as well improvement these traithrough selection and introduction new alleles, lines, accessions into breeding activity from both exotic indigenous collections, aids in id...
-1,3-Glucanase ( Glu) expression in seeds plays important roles in the regulation of seed germination, dormancy and in the defence against seed pathogens. A thick -1,3-glucan layer is typical for the seed envelope of cucurbitaceous species, confers seed semipermeability and is degraded during germination. In many species with coat-imposed dormancy, the seed envelope confers a physical constrain...
Test data is needed to test any database application, but of extra importance when testing business intelligence/data warehousing systems, since they often require a larger volume of data and also often lack a user interface for entering data. This thesis describes Le Generator—a prototype of a framework for test data synthesis implemented in the Python programming language. I describe backgrou...
The purple leaf pigmentation mainly associated with anthocyanins accumulation is common in Brassica but the mechanisms of its production and its potential physiological functions are poorly understood. Here, we performed the phenotypic, cytological, physiological, and comparative leaves transcriptome analyses of 11 different varieties belonging to five Brassica species with purple or green leav...
Exposure of the mature Arabidopsis (Arabidopsis thaliana) seed to water results in the rapid release of pectinaceous mucilage from the outer cells of the testa. Once released, mucilage completely envelops the seed in a gel-like capsule. The physical force required to rupture the outer cell wall of the testa comes from the swelling of the mucilage as it expands rapidly following hydration. In th...
Sorghum is a good source of phenolic compounds with a variety of genetically dependent types and levels including phenolic acids, flavonoids, and condensed tannins. Most sorghums do not contain condensed tannins, but all contain phenolic acids. Pigmented sorghums contain unique anthocyanins that could be potential food colorants. Some sorghums have a prominent pigmented testa that contains cond...
Starting in 1966 with the introduction of the ELIZA chatbot, a great deal of effort has been devoted towards the goal of developing a chatbot system that would be able to pass the Turing Test. These efforts have resulted in the creation of a variety of technologies and have taken a variety of approaches. In this paper we compare and discuss the different technologies used in the chatbots which ...
Wireless Sensor Networks (WSNs) are increasingly being adopted in critical applications. In these networks undesired events may undermine the reliability level; thus their effects need to be properly assessed from the early stages of the development process onwards to minimize the chances of unexpected problems during use. In this paper we propose two heuristic strategies: what-if analysis and ...
This article summarizes a symposium organized and cochaired by Maria Testa and presented at the 2005 Annual Meeting of the Research Society on Alcoholism, in Santa Barbara, California. The symposium explored issues relevant to understanding the function of placebo conditions and to interpreting placebo effects. Cochair Mark Fillmore began with an overview of the use of placebo conditions in alc...
