IDENTIFICATION OF PROTEIN MARKERS LINKED TO DROUGHT TOLERANCE IN NEW IRANIAN RICE GERMPLASM

Abstract

As with other crops, loss of enough water resources especially during low falling periods is one of the main problems in rice cultivation and production in most regions of Asia. Identification of protein markers linked to drought tolerance can facilitate rice breeding process for developing new elite drought tolerant varieties. In proteome analysis of studied rice germplasm, protein was extracted from leaves of the rice plants under natural growth condition by Damerval method. Concentration of the protein samples was measured by Bradford method. Then, Two-dimensional gel electrophoresis technique was used to identify protein markers linked to drought tolerance in studied rice germplasm. Protein spots available in gel profiles of studied samples were analyzed and compared together in Melanie software. Overall, molecular data analysis of protein spots available in 2D gel profiles indicated that 20 reproducible protein spots were linked to drought tolerance in the new Iranian drought tolerant genotype.

Neutron Diffraction Study of Microstructure of Nanocrystalline Cubic Niobium Carbides from NbC0.77 to NbC0.96

Abstract

The microstructure of nanocrystalline nonstoichiometric niobium carbides NbC0.77, NbC0.84, NbC0.96 powders produced by high-energy ball milling has been investigated by time-of-flight (TOF) high resolution neutron diffraction. The diffraction patterns have been collected with the high resolution Fourier diffractometer HRFD by using the TOF mode of data acquisition. The nanocrystalline ball-milled powders have a microinhomogeneous structure, in which two fractions with different particle size and composition can be identified. The average sizes of the coherent scattering regions and microstrains in nanocrystallites with allowance for the anisotropy of the deformation distortions have been estimated. It is shown that TOF neutron diffraction patterns can provide the very accurate data for microstructure analysis of nanocrystalline powders.

The Importance of Visual Management as a Motivator of Human Capital and Optimization of the Results of the Productive System

Abstract

This paper presents new achievements in people management that allow for the increase of competitive edge of organizations. It also points out the importance of the implementation of new production methods such as process automation or agility and shows the need of employees’ participation and their value within the organization, demonstrating the fundamental importance of people for business growth and development. By this article the management of human resources is highlighted and the resulting optimization of the production system through the visual management and its quality tools is shown. In this sense, a conceptual approach to talent guidance based on management and productive control was used in this article. Modern corporations pursue results through production management system improvements, automation of production lines and advancement of technological skills. The development of production techniques such as Just-in-Time and Kanban supports decision making, facilitates process management and benefits human assets. Retaining of brains has become the prime issue for the success of corporations. These profound changes have given rise to a new society, the knowledge society. It is demonstrated that human capital in organizations has the individual as the main character and generator of knowledge, being a differential in the establishment of indicators and in obtaining results to achieve new goals and the success of the organization. Recent studies have shown relevant results in relation to the influence of the companies favorable organizational climate on the motivation of its employees and in interviews conducted in these studies, the percentages are observed above 73%. The study of the strategies used by the companies shows as results the valorization of the talent as competitive differential and stimulator of the process of innovation of the team and of the project management, besides having a strategic vision of the business in which the organization is inserted.
