  • Carbohydrates serve three different principal functions in the metabolism of plants. They are the primary products of energy fixation, they are important transport metabolites, and they are deposited as structural or storage compounds. Modification of carbohydrate metabolism therefore covers approaches to modify yield, to change sink/source relationships and thereby alter the ratio of harvestable material, and to improve the quality of crop plants. The scope of this article is to summarize research done at the Max-Planck-Institute related to the first two fields and to present in some detail what we learned, when we established a new carbohydrate storage form in potato.

  • A convex region covers a family of curves if it contains a congruent copy of each curve in the family, and a 'worm problem' for that family is to find the convex region of smallest area. In this paper, we find the smallest triangular cover of any prescribed shape for the family S of all triangles of diameter 1.

  • We have presented the tracing algorithm for center pixel of character image. Character image was read by scanner device. Performing the tracing process, it can be possible to detect feature points, such as branch point, stroke of 4 directions. So, the tracing process covers the thinning and feature point detection process for improving the processing time. Usage of suggested tracing algorithm instead of thinning that is the preprocessing of character recognition increases speed up to 5 times. The preprocessing chip has been designed by using single layer perceptron algorithm.

  • About 440,000 $\textrm{km}^2$, about twice the size of the Korean Peninsula is covered by loess deposits in China. Along the middle reaches of the Huanghe River, mainly in Shaanxi and in Gansu province loess plateau covers vast area amounting to 273,000 $\textrm{km}^2$ Chinese studies on loess and loessial slopes are summarized. And some of the U. S. study and others are also presented for comparison.

  • Safety of packaging foods has increasingly been a significant global issue in recent years. This paper aims to present the broad information and perspectives on food packaging safety in Thailand. This paper compiles the use of different packaging materials, their safety characteristics, and the regulations in Thailand in accordance with the world regulations. In addition, it covers the opinion of various parties related to food packaging in Thailand. Some scientific based results coupled with the interviewing and questionnaire data from the previous and ongoing researches are discussed here. This paper summarizes the food packaging safety in Thailand today and proposed the trends tomorrow along with the future world requirements.

  • In this paper, we consider a diffusive delayed predator-prey model with Beddington-DeAngelis type functional response under homogeneous Neumann boundary conditions, where the discrete time delay covers the period from the birth of immature preys to their maturity. We investigate the global existence of nonnegative solutions and the long-term behavior of the time-dependent solution of the model.

  • Many radiological modalities has been applied to medicine as a basic fundamental diagnosis and therapy recently. The prevalence of computer systems affect most images to be digitized. However conventional X-ray film images are not digital images eventhough they covers 70% of all radiologica images. This is the hinderacne of building PACS. In this paper all radiological digital imaging parts such as DSA. CR. MRI. SPECT. PET and ultrasonography were briefly introduced and the applications were described. In brief digital radiography contribute to enhance the medical service quality. And the digital substituition of conventional X-ray film image is inevitable.
