zcebe Co-Supervisor: Prof. Dr. Ugur Ersoy July 2005, 135 pages The minimum spiral ratio equation given in the codes is derived by equating the strength at the second peak to the strength at the first peak for spiral columns tested under uniaxial load. In this study, specimen behavior under combined bending and axial load was taken as basis while deriving proposed equations. Analyses were carried out by using a Moment-Curvature program. For normal strength concrete, one regression and one simplified equation giving minimum spiral ratio are proposed. Difference between two equations arises from the number in front of (Ac/Ack). In regression equation, this number is calculated by means of a function. In simplified equation, this number is a constant. For high strength concrete, a different regression equation is proposed which is valid for concrete strengths up to 95 MPa. Simplified equation proposed for normal strength concrete is also proposed for high strength concrete up to concrete strengths of 120 MPa. It was found that
(i) Simplified equation proposed for normal and high strength concrete yielded consistent results in the range of variables studied
(ii) Except some points, regression equations yielded consistent results
(iii) It is recommended to use simplified equation instead of regression and code equations since it yields more consistent results than code and regression equations. Keywords: Confined Concrete, Ductility, Moment-Curvature, Minimum Spiral Volumetric Ratio

Full textThis work investigates the behaviour of Ra within a forest ecosystem (Montiers, Meuse). It is based on the quantification of several isotopic tracers (U- and Th- series disequilibria, isotopic ratios of 228Ra/226Ra and 87Sr/86Sr) in the different compartments of the water-soil-plant system. The research goals were : 1) to study the mobility of Ra and its radioactive ascendants in the separated mineral fractions of a soil profile, 2) to evaluate the transfer of Ra to the water-plant system, 3) to characterise the transfer of Ra and its residence time onto the vegetation, 4) to realise an account of the biogeochemical cycle of Ra. This work shows a strong redistribution of U, Th and Ra depending on their respective affinities with the different mineral fractions of the soil. Despite being predominantly concentrated in the clay fraction (<2 µm) of the soil, our findings indicate that trees (beeches) mostly extract Ra from the soil’s iron oxides. The subsequent transfer of this nuclide from the roots to the foliage is lesser than that of other alkaline-earth metals, leading to a vegetal residence time on the order of a few years (2.6 ± 1.6 years). Finally, the biogeochemical cycle of Ra is characterised by the degradation flux of fine-roots rather than that of leaves, by a negligible atmospheric input and by a strong weathering rate. Ra presents in the latter originates almost uniquely from litter degradation and does not pass through gravitational soil solutions

Full textMineral exploration in Australia today faces a great challenge: to efficiently detect mineralisation buried beneath extensive regolith cover. Because their roots penetrate the regolith cover, establishing the elemental signatures of certain plants (biogeochemical exploration) can aid in the detection of buried ore deposits. At the highly prospective Mount Painter Inlier, Eucalyptus camaldulensis (river red gum) was sampled in the ranges and extending out onto the plains bordering Lake Frome. Here it is shown that the leaves from Eucalyptus trees can detect a range of elements including important pathfinder elements related to U mineralisation. A significant finding of this study is that the sediments thought to be associated with the geochemical transport and host of U mineralisation, like those that host the Four Mile U deposit, have relatively elevated U2/Th values. The geological setting of these locally elevated U results also appears to be equivalent to the Four Mile mineralisation, based on available field exposures. Therefore, this area could well represent a biogeochemical expression of mineralisation equivalent to the soon to be mined Four Mile U deposit. This study demonstrated that Eucalyptus biogeochemistry has significant advantages over other approaches in that it is cost and time efficient, culturally unobtrusive, and can identify relationships between plant biogeochemistry and the underlying geological substrate, in particular, U-mineralisation. The examination of more Eucalyptus camaldulensis (and more widespread species in the area) from surrounding areas therefore also warrants further investigation.

In this thesis, a multiple pulse transmission for hybrid TH/DS impulse radio UWB systems is studied. Using Binary Phase Shift Keying(BPSK) modulation and Bi-orthogonal Pulse Position Modulation(BPPM), and an accurate performance analysis of proposed system using BPSK modulation is provided. For proposed system using BPPM modulation make a simulation to understand the parameter change impact on system performance. The advantage of the proposed system is to increase the transmission rate and the system capacity, and also improve the system performance in terms of using TH/DS multiple access technology. Proposed system using BPSK modulation, so the original can only transmit one bit of BPSK modulation, into Q bits can be send to increase the transmission rate simultaneously. Based on the characteristic function analytical method, we derive the probability distribution of multiple access interference and the system average symbol error rate. Many of the above pulse transmission system using BPSK modulation combined with pulse position modulation (PPM), which form a multiple pulse transmission of the N-ary Biorthogonal Pulse Position modulation (BPPM), to increase the modulation level (N).The simulations used to verify the analytical results are carried out in AWGN and actual UWB fading channel. In order to numerical analysis and simulation results can be a fair comparison , we will be one of the parameters Tp fixed 0.7ns (reciprocal of bandwidth can be approximated) ,namely, the bandwidth is fixed, and fixed data transmission rate (Tb / Tp) is 32. From the numerical analysis and simulation results, we can conclude when other system parameters are fixed that the performance of system is improved by increasing the number of frames. As the number of users increase, the system performance degrades more. The theoretical analysis of the proposed system can be verified from the simulation results. Consider the parameters in proposed system using BPSK and BPPM modulation, which fixed (Tb / Tp ) is 32, the more pulse transmit simultaneously the more improve in the performance obviously. In the proposed system using BPPM modulation, the system performance can be improve as the number of the pulse position is increased.
