101. Electron scattering by ytterbium: I. Excitation of the 4f146s6p 1P1resonance state and elastic collision

Author

Predojevic, B, Sevic, D, Pejcev, V, Marinkovic, B P, and Filipovic, D M

Abstract

Differential cross sections (DCSs) for electron-impact excitation of the 4f146s6p 1P1resonance state of ytterbium were measured at 10, 20, 40, 60 and 80 eV incident electron energies (E0) and scattering angles (?) between 2° and 150°. The absolute DCS scale for the 1P1state was determined through normalization of its relative DCSs to the optical oscillator strength using the forward scattering function method. DCSs for elastic electron scattering by ytterbium were measured at the same energies for ? between 10° and 150°. Elastic-to-inelastic intensity ratios were obtained from energy-loss spectra recorded with overall energy resolution of 65 meV (FWHM) and angular resolution of 1.5°. Both inelastic and elastic DCSs were extrapolated to 0° and 180° and numerically integrated to yield integral, momentum transfer and viscosity cross sections. Our results are compared with scarce experimental and theoretical data.

104. BANDPASS VIBRATION ABSORBER

Author

Filipovic´, D. and Schro¨der, D.

Abstract

A new concept for active vibration absorption is presented. A properly designed compensator in the local feedback converts the well-known passive absorber into a bandpass absorber. Such an absorber amplifies frequencies in a given frequency range, thus almost producing resonance for all these frequencies. If such an absorber is attached to a vibrating body, it absorbs vibrations at all frequencies that belong to the bandpass range. The presented compensator design guarantees the stability of the system. The proposed concept needs an additional local control of the absorber mass displacement, which has also been resolved. The paper presents the idea, the design procedure, and the simulation results that prove the relevance of the solution.

108. Landscape suitability assessment and mapping of potential land use conflicts in the function of sustainable landscape management: A case study of Branicevo District, Serbia

Author

Zivkovic, M., Filipovic, D., Novkovic, I., Radic, B., Aleksandar Djordjevic, and Mladenovic, N.

Subjects
Landscape functions, agriculture production, landscape suitability assessment, recreational tourism, geoecological evaluation, conflict analysis
Abstract

In this study, the landscape suitability assessment was used to quantify and map the relationships between landscape functions (agriculture production, recreational tourism and mineral resources exploitation). Obtained results can be treated in two ways. The greatest potentials for conflict are observed in the multifunctional landscapes of Branicevo District, where the mapped landscape functions carry high values. In the same way, the values obtained by determining the degree of suitability reflect development opportunities, and indicate terrains most suitable for the development of agriculture production and recreational tourism. The methodological approach is based on the combined application of the Relative Relief Evaluation Method and V-Wert method. GIS data processing produced synthesis maps, which presented spatial units, grouped into categories with values conditioned by the heterogeneous landscape structure. Spatial units indicating high and conditionally high level of potential conflict between agriculture production and recreational tourism occupy an area of 16.01%, while spatial units where high and conditionally high level of potential conflict between all three landscape functions occupy 4.91% of the district. The most suitable terrains for agriculture production development occupy 23.17% of the area, while the spatial units indicating terrains most valuable for recreational tourism development occupy 7.43% of the study area.

Abstract

In the 12,000 years preceding the Industrial Revolution, human activities led to significant changes in land cover, plant and animal distributions, surface hydrology, and biochemical cycles. Earth system models suggest that this anthropogenic land cover change influenced regional and global climate. However, the representation of past land use in earth system models is currently oversimplified. As a result, there are large uncertainties in the current understanding of the past and current state of the earth system. In order to improve representation of the variety and scale of impacts that past land use had on the earth system, a global effort is underway to aggregate and synthesize archaeological and historical evidence of land use systems. Here we present a simple, hierarchical classification of land use systems designed to be used with archaeological and historical data at a global scale and a schema of codes that identify land use practices common to a range of systems, both implemented in a geospatial database. The classification scheme and database resulted from an extensive process of consultation with researchers worldwide. Our scheme is designed to deliver consistent, empirically robust data for the improvement of land use models, while simultaneously allowing for a comparative, detailed mapping of land use relevant to the needs of historical scholars. To illustrate the benefits of the classification scheme and methods for mapping historical land use, we apply it to Mesopotamia and Arabia at 6 kya (c. 4000 BCE). The scheme will be used to describe land use by the Past Global Changes (PAGES) LandCover6k working group, an international project comprised of archaeologists, historians, geographers, paleoecologists, and modelers. Beyond this, the scheme has a wide utility for creating a common language between research and policy communities, linking archaeologists with climate modelers, biodiversity conservation workers and initiatives.

118. ASSESSMENT OF RELATIONS BETWEEN STEWARDSHIP AND STAKEHOLDER THEORY.

Abstract

Developed as alternative to agency theory, stewardship theory rejects the agency theory assumptions and presupposes context in which managers perceive that satisfying stockholders goals is also in their personal interest. With the extension of the corporation duties beyond the shareholders based upon the assumption that the corporation had citizenship responsibilities within society and an array of ethical and moral obligations to different stakeholders, intention of this paper is to compare stewardship theory to stakeholder theory specially concerning relations towards employees. Presented theoretical assumptions indicate that in reality, stewardship theory is consistent to stakeholder theory and upgrades stakeholder theory. [ABSTRACT FROM AUTHOR]

Abstract

Agency theory is an important, yet controversial, theory. This paper reviews agency theory and its contributions to organization theory. Assessment is done in comparison to stewardship theory. The intent is to clarify some of the confusions surrounding agency theory and to alert organizational scholars when using agency theory. Agency theory is confirmed as useful addition to organizational theory, but the paper offers alternative propositions based on a relaxing of agency theory's assumptions. [ABSTRACT FROM AUTHOR]

Abstract

A 15-45 GHz broadside coupled rectangular coaxial line based phase shifter is demonstrated. An analysis, the design, fabrication, measurements and a sensitivity study are conducted and discussed. Amplitude and phase imbalances of <0.25 dB and <2.5°, respectively, are measured. Input port reflection coefficients < -10 dB and an insertion loss below 0.6 dB are also obtained. A conducted sensitivity study shows the small dependence of the device performance on the process variations. The presented results may pave the way for multi-octave analogue phase shifters and beam formers throughout the millimetre-wave range. [ABSTRACT FROM AUTHOR]

Abstract

Various physical and mechanical properties of almond (Prunus dulcis cv. 'Fra Giulio Grande') nuts and kernels were determined at four moisture content levels (9. 74%, 16.35%, 23.28%, and 30.46% wet basis). The average length, width, thickness, equivalent diameter, unit mass, volume, and sphericity of nuts were 36.77 mm, 26.70 mm, 19.01 mm, 26.51 rang 6.06 g, 9.83 cm³, and 72.13%, respectively, while the corresponding values for kernels were 25.98 mm, 16.19 nun, 8.63 mm, 15.33 mm, 1.57 g, 1.93 cm³ and 59.01%, respectively, at a moisture content of 9.74% wet basis (w.b.). In the moisture range from 9. 74% to 30.46% w.b., studies on the rewetted nut showed that the bulk density of nut and kernel decreased from 488 to 401 kg m-3 and from 559 to 475 kg m-3 respectively. The true density of nut decreased from 826 to 730 kg m-3, while for kernel it decreased from 922 to 844 kg m-3. The porosity of nut increased from 40. 94% to 45.08%, while porosity of kernel increased from 39.43% to 43.69%. Tire projected area for nut and kernel increased from 745 to 823 mm² and from 318 to 357 mm² respectively. In the same moisture range, tire static coefficient of friction for nuts on three different material surfaces varied from 0.291 to 0.415 on aluminum, from 0.338 to 0.462 on plywood, and from 0.392 to 0.529 on rubber The corresponding values for kernels were 0.335 to 0.441, 0.381 to 0.496, and 0.484 to 0.589, respectively. The maximum force for nut cracking occurred in the longitudinal direction and tire minimum force transversely in thickness direction. For all compression directions, the force required to crack the nut decreased with increasing moisture content. The results of this study could be applied to optimize and develop of machines for handling and cracking of this almond cultivar. [ABSTRACT FROM AUTHOR]
