description: Zusammenfassung : Als Folge des Health Check der Gemeinsamen Agrarpolitik sowie des europäischen Konjunkturprogramms wurden die Mittel des Europäischen Landwirtschaftsfonds zur Entwicklung des ländlichen Raums (ELER) aufgestockt, um damit geeignete Maßnahmen zur Reaktion auf die „neuen Herausforderungen“ (Klimawandel, erneuerbare Energien, Wassermanagement, Biodiversität, Umstrukturierung des Milchsektors) zu ergreifen. Dieser Bericht analysiert die Änderungen, die die deutschen Bundesländer daraufhin im Jahr 2009 in ihren ländlichen Entwicklungsprogrammen vorgenommen haben. Die Analyse zeigt den großen Unterschied, der zwischen der formalen Anrechnung dieser zusätzlichen Mittel auf Maßnahmen gemäß den Prioritäten des Health Check und der tatsächlichen Mittelverteilung in den Programmen besteht. Umschichtungen von frei werdenden Mitteln in andere Maßnahmen führen in der Summe zu einer Stärkung von Maßnahmen, die vor allem eine Einkommensstützung landwirtschaftlicher Betriebe bewirken und kaum mit anspruchsvollen Bedingungen an zusätzliche Umweltleistungen der Landwirtschaft verknüpft sind. --------------------------------------------------------------------------------------------------------------------------------------- Summary: As a result of the Health Check of the Common Agricultural Policy and the European Economic Recovery Plan, resources of the European Agricultural Funds for Rural Development (EAFRD) were increased in order to take appropriate measures against the “new challenges” (climate change, renewable energies, water management, biodiversity, re-structuring of the dairy sector). This report analyses how the German federal states (Länder) in 2009 adjusted their Rural Development Programmes to these requirements. The analysis shows the clear difference between the formal assignment of additional funds towards measures according to the Health Check priorities, and the actual distribution of funds in the programmes. Shifting of released funds to other measures leads to a strengthening of measures which primarily sustain incomes of agricultural holdings. These measures are hardly tied to additional environmental benefits as a condition for support.

description: We discuss the possibility of trapping polar molecules in the standing-wave electromagnetic field of a microwave resonant cavity. Such a trap has several novel features that make it very attractive for the development of ultracold molecule sources. Using commonly available technologies, microwave traps can be built with large depth (up to several Kelvin) and acceptance volume (up to several cm^3), suitable for efficient loading with currently available sources of cold polar molecules. Unlike most previous traps for molecules, this technology can be used to confine the strong-field seeking absolute ground state of the molecule, in a free-space maximum of the microwave electric field. Such ground state molecules should be immune to inelastic collisional losses. We calculate elastic collision cross-sections for the trapped molecules, due to the electrical polarization of the molecules at the trap center, and find that they are extraordinarily large. Thus, molecules in a microwave trap should be very amenable to sympathetic and/or evaporative cooling. The combination of these properties seems to open a clear path to producing large samples of polar molecules at temperatures much lower than has been possible previously.

description: FU Orionis objects (FUors) are rapidly-accreting, pre-main sequence objects that are known to exhibit large outbursts at optical and near-infrared wavelengths, with post-eruption, small-scale photometric variability superimposed on longer-term trends. In contrast, little is known about the variability of FUors at longer wavelengths. To explore this further, we observed six FUor objects using the NOrthern Extended Millimeter Array (NOEMA) and for a subset of three objects we obtained coordinated observations with NOEMA and the Lowell Discovery Telescope (LDT). In combination with previously published NOEMA observations from 2014, our 2017 observations of V1735 Cyg provide the first detection of variability in an FUor object at 2.7 mm. In the absence of significant optical variability, we discount the possibility that the mm flux density changed as a result of irradiation from the central disk. In addition, a change in the dust mass due to infall is highly unlikely. A plausible explanation for the change in 2.7 mm flux density is variability in free-free emission due to changes in the object's jet/wind. Thus, it may be that free-free emission in some FUor objects is significant at $\sim$3 mm and must be considered when deriving disk masses in order to help constrain the mechanism responsible for triggering FUor outbursts.

Numerical optimal control with applications in aerospace
Creators: name: Nie, Yuanbo
Publisher: name: Imperial College London
Year: 2020

description: This thesis explores various computational aspects of solving nonlinear, continuous-time dynamic optimization problems (DOPs) numerically. Firstly, a direct transcription method for solving DOPs is proposed, named the integrated residual method (IRM). Instead of forcing the dynamic constraints to be satisfied only at a selected number of points as in direct collocation, this new approach alternates between minimizing and constraining the squared norm of the dynamic constraint residuals integrated along the whole solution trajectories. The method is capable of obtaining solutions of higher accuracy for the same mesh compared to direct collocation methods, enabling a flexible trade-off between solution accuracy and optimality, and providing reliable solutions for challenging problems, including those with singular arcs and high-index differential-algebraic equations. A number of techniques have also been proposed in this work for efficient numerical solution of large scale and challenging DOPs. A general approach for direct implementation of rate constraints on the discretization mesh is proposed. Unlike conventional approaches that may lead to singular control arcs, the solution of this on-mesh implementation has better numerical properties, while achieving computational speedups. Another development is related to the handling of inactive constraints, which do not contribute to the solution of DOPs, but increase the problem size and burden the numerical computations. A strategy to systematically remove the inactive and redundant constraints under a mesh refinement framework is proposed. The last part of this work focuses on the use of DOPs in aerospace applications, with a number of topics studied. Using example scenarios of intercontinental flights, the benefits of formulating DOPs directly according to problem specifications are demonstrated, with notable savings in fuel usage. The numerical challenges with direct collocation are also identified, with the IRM obtaining solutions of higher accuracy, and at the same time suppressing the singular arc fluctuations.

description: Infrared and optical spectra of SN 1998bu at an age of one year after explosion are presented. The data show evidence for the radioactive decay of 56Co to 56Fe, long assumed to be the powering source for the supernova light curve past maximum light. The spectra provide direct evidence for at least 0.4 solar masses of iron being present in the ejecta of the supernova. The fits to the data also show that the widths of the emission lines increase with time. Photometric measurements in the H-band show that the supernova is not fading during the observation period. This is consistent with theoretical expectations.

Webster Sequences, Apportionment Problems, and Just-In-Time Sequencing

description: Given a real number $α\in (0,1)$, we define the Webster sequence of density $α$ to be $W_α= (\lceil(n-1/2) / α\rceil)_{n\in\mathbb{N}}$, where $\lceil x \rceil$ is the ceiling function. It is known that if $α$ and $β$ are irrational with $α+ β= 1$, then $W_α$ and $W_β$ partition $\mathbb{N}$. On the other hand, an analogous result for three-part partitions does not hold: There does not exist a partition of $\mathbb{N}$ into sequences $W_α, W_β, W_γ$ with $α, β, γ$ irrational. In this paper, we consider the question of how close one can come to a three-part partition of $\mathbb{N}$ into Webster sequences with prescribed densities $α, β, γ$. We show that if $α, β, γ$ are irrational with $α+ β+γ= 1$, there exists a partition of $\mathbb{N}$ into sequences of densities $α, β, γ$, in which one of the sequences is a Webster sequence and the other two are "almost" Webster sequences that are obtained from Webster sequences by perturbing some elements by at most 1. We also provide two efficient algorithms to construct such partitions. The first algorithm outputs the $n$th element of each sequence in $O(1)$ time and the second algorithm gives the assignment of the $m$th positive integer to a sequence in $O(1)$ time. We show that the results are best-possible in several respects. Moreover, we describe applications of these results to apportionment and optimal scheduling problems.

Arsenic removal by iron oxides
Creators: name: Aredes, Sonia
Publisher: name: University of British Columbia
Year: 2010

description: Arsenic has long been recognized as a toxin and carcinogen. Arsenic contaminated drinking water probably poses the greatest threat to human health. A successful treatment for removing arsenic from drinking water requires an understanding of arsenic chemistry and the physical-chemical processes that occur during each treatment step. Iron oxide (Fe-Ox) minerals showed good efficiency for arsenic removal (Simeonova 2000, Matis et.al., 1999). Additionally, naturally occurring iron oxides are more attractive for arsenic removal from contaminated water than the synthetic oxides because they are more cost effective. However, few studies have been carried out on the feasibility of their use as adsorbents for arsenic removal. Hematite, magnetite, goethite and laterite have been studied in their role as arsenic adsorbents. Results showed that all of them are suitable as arsenic adsorbents. Electroacoustic Tests (ET) tests showed that arsenic adsorption occurs over the whole pH range considered (4-11) and also that the Fe-Ox have IEP at pH between 6.5 and 8.5. Their surface charge is negative at pHpzc. The presence of inner sphere complex, which implies stability of the arsenic adsorbed onto Fe-Ox because of covalent bonding, was shown by ET and leaching tests. Leaching tests by MgCl₂ were performed to study the stability of the adsorption products and results expressed on a weight percentage basis showed that hematite had 60.2%, magnetite 75.4%, goethite 78.0% and laterite 86.2% of arsenic strongly fixed. While these results expressed on a surface area basis showed that hematite had 0.16mg/m² , magnetite 0.11mg/m² , goethite 0.065 mg/m² and laterite 0.011 mg/m² of arsenic strongly fixed. In addition, this study presents a simple method developed to remove arsenic from water using natural iron oxides (Fe-Ox) minerals. The method involves mixing natural iron mineral bearing soils (lateritic soils) with arsenic contaminated water for ten minutes and then filtering (coffee filter). The aadsorption capacity of laterite was estimated at 0.1 lmg/m². After addition, arsenic levels in the treated water were below drinking water standards. The treatment method is inexpensive and simple, making it suitable for house hold use.

description: We discuss if one can verify the MSW effect in neutrino oscillations at a high confidence level in long-baseline experiments. We demonstrate that for long enough baselines at neutrino factories, the matter effect sensitivity is, as opposed to the mass hierarchy sensitivity, not suppressed by $\sin^2 2 θ_{13}$ because it is driven by the solar oscillations in the appearance probability. Furthermore, we show that for the parameter independent direct verification of the MSW effect at long-baseline experiments, a neutrino factory with a baseline of at least 6000 km is needed. For superbeams, we do not find a $5σ$ discovery potential of the MSW effect independent of $\sin^2 2 θ_{13}$. We finally summarize different methods to test the MSW effect.

Imaginary-field-driven phase transition for the $2$D Ising antiferromagnet: A fidelity-susceptibility approach
Creators: name: Nishiyama, Yoshihiro
Publisher: name: arXiv
Year: 2020
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: The square-lattice Ising antiferromagnet subjected to the imaginary magnetic field $H=i θT /2 $ with the "topological" angle $θ$ and temperature $T$ was investigated by means of the transfer-matrix method. Here, as a probe to detect the order-disorder phase transition, we adopt an extended version of the fidelity susceptibility $χ_F^{(θ)}$, which makes sense even for such a non-hermitian transfer matrix. As a preliminary survey, for an intermediate value of $θ$, we examined the finite-size-scaling behavior of $χ_F^{(θ)}$, and found a pronounced signature for the criticality; note that the magnetic susceptibility exhibits a weak (logarithmic) singularity at the Néel temperature. Thereby, we turn to the analysis of the power-law singularity of the phase boundary at $θ=π$. With $θ-π$ scaled properly, the $χ_F^{(θ)}$ data are cast into the crossover scaling formula, indicating that the phase boundary is shaped concavely. Such a feature makes a marked contrast to that of the mean-field theory.

description: This PhD thesis explores humpback whale song research, cumulative cultural evolution (CCE), aesthetics, and public engagement. It comprises five chapters, each offering a comprehensive analysis of these topics. Chapter 1 outlines humpback whale song research and its relevance to CCE and vocal learning debates. It emphasises the effective use of whale song in public engagement for science and conservation. Chapter 2 presents a conceptual analysis of the compatibility between CCE and aesthetics. Interdisciplinary discussions explore challenges in reconciling aesthetic culture with prevailing philosophical views. The chapter also highlights tensions between cultural evolution in aesthetic and technological domains, contributing to debates on reconstructive and preservative theories. Chapter 3 tracks the evolution of a specific humpback whale song unit type across different themes within a song type over a breeding season. Methodological efficiencies enable a larger dataset analysis, providing insights into vocal production learning hypotheses. Chapter 4 expands on Chapter 3 by examining the evolution of a song unit type over two seasons and in a different ocean basin. Matching song types across locations reveals the extraordinary scale of humpback song cultural evolution. Evidence supports the vocal production learning hypothesis and challenges the notion of an innate template. Chapter 5 diverges thematically and methodologically, focusing on two case studies in public engagement. An interactive science exhibition and a community science event demonstrate successful engagement and impact on low science capital public groups. This thesis contributes to understanding humpback whale song research, CCE, aesthetics, and public engagement. It offers interdisciplinary perspectives, empirical investigations, and valuable insights into cultural evolution complexities. The thesis emphasises the importance of engaging the public in science while showcasing the impact on both the public and the researcher.

description: The problem of graph learning concerns the construction of an explicit topological structure revealing the relationship between nodes representing data entities, which plays an increasingly important role in the success of many graph-based representations and algorithms in the field of machine learning and graph signal processing. In this paper, we propose a novel graph learning framework that incorporates the node-side and observation-side information, and in particular the covariates that help to explain the dependency structures in graph signals. To this end, we consider graph signals as functions in the reproducing kernel Hilbert space associated with a Kronecker product kernel, and integrate functional learning with smoothness-promoting graph learning to learn a graph representing the relationship between nodes. The functional learning increases the robustness of graph learning against missing and incomplete information in the graph signals. In addition, we develop a novel graph-based regularisation method which, when combined with the Kronecker product kernel, enables our model to capture both the dependency explained by the graph and the dependency due to graph signals observed under different but related circumstances, e.g. different points in time. The latter means the graph signals are free from the i.i.d. assumptions required by the classical graph learning models. Experiments on both synthetic and real-world data show that our methods outperform the state-of-the-art models in learning a meaningful graph topology from graph signals, in particular under heavy noise, missing values, and multiple dependency.

description: In this work we extend our previously developed formalism of Newtonian multi-fluid hydrodynamics to allow for coupling between the fluids and the electromagnetic and gravitational field. This is achieved within the convective variational principle by using a standard minimal coupling prescription. In addition to the conservation of total energy and momentum, we derive the conservation of canonical vorticity and helicity, which generalize the corresponding conserved quantities of uncharged fluids. We discuss the application of this formalism to electrically conducting systems, magnetohydrodynamics and superconductivity. The equations of electric conductors derived here are more general than those found in the standard description of such systems, in which the effect of entrainment is overlooked, despite the fact that it will generally be present in any conducting multi-constituent system.

description: The double ionization potential (DIP) equation-of-motion (EOM) coupled-cluster (CC) method with a full treatment of 4-hole-2-particle (4$h$-2$p$) correlations and triply excited clusters, abbreviated as DIP-EOMCCSDT(4$h$-2$p$), and its approximate form called DIP-EOMCCSD(T)(a)(4$h$-2$p$) have been formulated and implemented in the open-source CCpy package available on GitHub. The resulting codes work with both nonrelativistic and spin-free scalar-relativistic Hamiltonians. By examining the DIPs of a few small molecules, for which accurate reference data are available, we demonstrate that the DIP-EOMCCSDT(4$h$-2$p$) and DIP-EOMCCSD(T)(a)(4$h$-2$p$) approaches improve the results obtained using the DIP-EOMCC methods truncated at 3$h$-1$p$ or 4$h$-2$p$ excitations on top of the CC calculations with singles and doubles.

description: The electronic structure of the rational approximants 1/1 Cd6Yb and 1/1 Cd6Ca to the stable icosahedral CdYb and CdCa quasicrystals is studied by the full-potential linear augmented plane wave method. A comparison is made between several structural models. We show that the (relativistic) spin-orbit (SO) interaction and electronic correlations that are not described by the usual local density approximation, are essential for an accurate description of the electronic structure. In particular, we show that the SO interaction is responsible for a splitting of the Cd-4d and Yb-4f peaks, and that the experimental peak positions can be reproduced by including a Hubbard U term in the Hamiltonian [U(Cd) = 5.6 eV, U(Yb) = 3.1 eV]. Our results show very good agreement with a photo-emission (PE) spectrum of 1/1 Cd6Yb [R. Tamura, Y. Murao, S. Takeuchi, T. Kiss, T. Yokoya, and S. Shin, Phys. Rev. B 65, 224207 (2002)] and a 350 eV PE spectrum of 1/1 Cd6Ca, which we present in this paper. Without the relativistic and correlation effects even a qualitative agreement with the PE spectra cannot be achieved.

description: This analysis uses the 2011 FAPRI-CARD (Food and Agricultural Policy Research Institute–Center for Agricultural and Rural Development) baseline to evaluate the impact of four alternative scenarios on U.S. and world agricultural markets, as well as on world fertilizer use and world agricultural greenhouse gas emissions. A key assumption in the 2011 baseline is that ethanol support policies disappear in 2012. The baseline also assumes that existing biofuel mandates remain in place and are binding. Two of the scenarios are adverse supply shocks, the first being a 10% increase in the price of nitrogen fertilizer in the United States, and the second, a reversion of cropland into forestland. The third scenario examines how lower energy prices would impact world agriculture. The fourth scenario reintroduces biofuel tax credits and duties. Given that the baseline excludes these policies, the fourth scenario is an attempt to understand the impact of these policies under the market conditions that prevail in early 2011. A key to understanding the results of this fourth scenario is that in the absence of tax credits and duties, the mandate drives biofuel use. Therefore, when the tax credits and duties are reintroduced, the impacts are relatively small. In general, the results show that the entire international commodity market system is remarkably robust with respect to policy changes in one country or in one sector. The policy implication is that domestic policy changes implemented by a large agricultural producer like the United States can have fairly significant impacts on the aggregate world commodity markets. A second point that emerges from the results is that the law of unintended consequences is at work in world agriculture. For example, a U.S. nitrogen tax that might presumably be motivated for environmental benefit results in an increase in world greenhouse gas emissions. A similar situation occurs in the afforestation scenario in which crop production shifts from high-yielding land in the United States to low-yielding land and probably native vegetation in the rest of the world, resulting in an unintended increase in global greenhouse gas emissions.

description: We analyse N-body galaxy merger experiments involving disc galaxies. Mergers of disc-bulge-halo models are compared to those of bulge-less, disc-halo models to quantify the effects of the central bulge on the merger dynamics and on the structure of the remnant. Our models explore galaxy mass ratios 1:1 through 3:1, and use higher bulge mass fraction than previous studies. A full comparison of structural and dynamical properties to observations is carried out. The presence of central bulges results in longer tidal tails, oblate final intrinsic shapes, surface brightness profiles with higher Sersic index, steeper rotation curves, and oblate-rotator internal dynamics. Mergers of bulge-less galaxies do not generate long-lasting tidal tails, and their strong triaxiality seems inconsistent with observations; these remnants show shells, which we do not find in models including central bulges. Giant ellipticals with boxy isophotes and anisotropic dynamics cannot be produced by the mergers modeled here; they could be the result of mergers between lower luminosity ellipticals, themselves plausibly formed in disc-disc mergers.

description: The band calculation scheme for $f$ electron compounds is developed on the basis of the dynamical mean field theory (DMFT) and the LMTO method. The auxiliary impurity problem is solved by a method named as NCA$f^{2}$v', which includes the correct exchange process of the $f^{1} \to f^{2}$ virtual excitation as the vertex correction to the non-crossing approximation (NCA) for the $f^{1} \to f^{0}$ fluctuation. This method leads to the correct magnitude of the Kondo temperature, $T_{\rm K}$, and makes it possible to carry out quantitative DMFT calculation including the crystalline field (CF) and the spin-orbit (SO) splitting of the self-energy. The magnetic excitation spectra are also calculated to estimate $T_{\rm K}$. It is applied to Ce metal and CeSb at T=300 K as the first step. In Ce metal, the hybridization intensity (HI) just below the Fermi energy is reduced in the DMFT band. The photo-emission spectra (PES) have a conspicuous SO side peak, similar to that of experiments. $T_{\rm K}$ is estimated to be about 70 K in $γ$-Ce, while to be about 1700 K in $α$-Ce. In CeSb, the double-peak-like structure of PES is reproduced. In addition, $T_{\rm K}$ which is not so low is obtained because HI is enhanced just at the Fermi energy in the DMFT band.

description: We determine colour gradients of $-0.15 \pm 0.08$ magnitudes per decade in radius in F450W$-$F606W and $-0.07 \pm 0.06$ magnitudes per decade in radius in F606W$-$F814W for a sample of 22 E/S0 galaxies in Abell 2218. These gradients are consistent with the existence of a mild ($\sim -0.3$ dex per decade in radius) gradient in metal abundance, (cf. previous work at lower and higher redshift for field and cluster galaxies). The size of the observed gradients is found to be independent of luminosity over a range spanning $M^*-1$ to $M^*+1.5$ and also to be independent of morphological type. These results suggest a fundamental similarity in the distributions of stellar populations in ellipticals and the bulges of lenticular galaxies. These results are not consistent with simple models of either monolithic collapse or hierarchical mergers.

description: We reanalyse the ratio $\varepsilon'/\varepsilon$ in the Standard Model (SM) using most recent hadronic matrix elements from the RBC-UKQCD collaboration in combination with most important NNLO QCD corrections to electroweak penguin contributions and the isospin-breaking corrections. We illustrate the importance of the latter by using their latest estimate from chiral perturbation theory (ChPT) based on the $octet$ approximation for lowest-lying mesons and a very recent estimate in the $nonet$ scheme that takes into account the contribution of $η_0$. We find $(\varepsilon'/\varepsilon)^{(8)}_\text{SM} = (17.4 \pm 6.1) \times 10^{-4}$ and $(\varepsilon'/\varepsilon)^{(9)}_\text{SM} = (13.9 \pm 5.2) \times 10^{-4}$, respectively. Despite a very good agreement with the measured value $(\varepsilon'/\varepsilon)_\text{exp} = (16.6 \pm 2.3) \times 10^{-4}$, the large error in $(\varepsilon'/\varepsilon)_\text{SM}$ still leaves room for significant new physics (BSM) contributions to this ratio. We update the 2018 master formula for $(\varepsilon'/\varepsilon)_\text{BSM}$ valid in any extension beyond the SM without additional light degrees of freedom. We provide new values of the penguin parameters $B_6^{(1/2)}(μ)$ and $B_8^{(3/2)}(μ)$ at the $μ$-scales used by the RBC-UKQCD collaboration and at lower scales $\mathcal{O}(1\,\text{GeV})$ used by ChPT and DQCD. We present semi-analytic formulae for $(\varepsilon'/\varepsilon)_\text{SM}$ in terms of these parameters and $\hatΩ_\text{eff}$ that summarizes isospin-breaking corrections to this ratio. We stress the importance of lattice calculations of the $\mathcal{O}(α_\text{em})$ contributions to the hadronic matrix elements necessary for the removal of renormalization scheme dependence at $\mathcal{O}(α_\text{em})$ in the present analyses of $\varepsilon'/\varepsilon$.

description: Here we present a neutron scattering-based study of magnetic excitations and magnetic order in NaYbO$_2$ under the application of an external magnetic field. The crystal electric field-split $J = 7/2$ multiplet structure is determined, revealing a mixed $|m_z>$ ground state doublet and is consistent with a recent report Ding et al. [1]. Our measurements further suggest signatures of exchange effects in the crystal field spectrum, manifested by a small splitting in energy of the transition into the first excited doublet. The field-dependence of the low-energy magnetic excitations across the transition from the quantum disordered ground state into the fluctuation-driven ordered regime is analyzed. Signs of a first-order phase transition into a noncollinear ordered state are revealed at the upper-field phase boundary of the ordered regime, and higher order magnon scattering, suggestive of strong magnon-magnon interactions, is resolved within the previously reported $up-up-down$ phase. Our results reveal a complex phase diagram of field-induced order and spin excitations within NaYbO$_2$ and demonstrate the dominant role of quantum fluctuations cross a broad range of fields within its interlayer frustrated triangular lattice.

description: We study non-linear adiabatic connection paths in density-functional theory using modified electron-electron interactions that perform a long-range/short-range separation of the Coulomb interaction. These adiabatic connections allows to define short-range exchange-correlation potentials and short-range local exchange-correlation energies per particle that we have calculated accurately for the He and Be atoms and compared to the corresponding quantities in the local density approximation (LDA). The results confirm that the LDA better describes exchange-correlation potentials and local exchange-correlation energies per particle when the range of the interaction is reduced.

description: UHECR are evaluated in the frame role of different nuclei composition. Most of the past and present models are considering proton or iron as their main courier. Some attention has been paid to the role of the UHECR light nuclei in recent years. We update here the lightest nuclei UHECR model, able to explain the nearest AGN or Star Burst sources with the few observed Hot Spot clustering in AUGER and TA array data. Any additional components of the heaviest nuclei with the highest energy, more bent and smeared, may also fit recent AUGER and TA homogeneous records at those energy edges.

description: Devido à expansão do cultivo da soja transgênica na região paulista do Médio Paranapanema analisou-se o retorno econômico comparativo entre a soja convencional e transgênica incorporando na análise o risco de alterações de variáveis críticas. Para determinar a rentabilidade líquida dos dois sistemas de produção sob condições de risco foi utilizado o método de simulação estocástica ou de Monte Carlo considerando três variáveis básicas: preço, produtividade e itens específicos do custo de produção para cada sistema, sabendo-se que na soja transgênica o manejo e controle de plantas daninhas são diferenciados. Concluiu-se que a soja transgênica apresentou nesse estudo maiores valores de retorno médio e menores indicadores de risco nas condições de preço, produtividade e custo. Verificou-se, também, que nos dois sistemas o preço de mercado da soja tem maior influência na variação da receita líquida do que a produtividade e o custo com herbicidas. --------------------------------------------The aim of this work was to analyze the economic return of conventional and transgenic soybean crop systems in the Middle Paranapanema region, in São Paulo State, Brazil, comprising risk analysis of critical variables changes. It was used the Monte Carlo Method simulation to determine the net profit of both systems under risk conditions, considering three critical variables, soybean prices, yield and herbicides use cost, because the transgenic soybean involves different types of weeds control. Throughout the results, could be observed that the transgenic soybean production system presented greater economic return and lower risk, based on the soybean prices, yield and herbicide costs considered in this study. In both systems the soybean prices had major influence on net income, than yield and herbicide costs.
