description: High temperatures, rain and high winds (at great intensity at times) have led to scientists and producers exploring options that enable greater control over the effects of weather on primary industries. In this study the suitability of an Italian pergola trellising system (the pergola) for table grapes was assessed on a property in Sunraysia. The study was established in 2009 through Palms Vineyard, the Australian Table Grape Association (ATGA) and Horticulture Australia Limited (HAL). The Victorian Department of Primary Industries (DPI) and Regional Development Victoria (RDV) gathered scientific and production information about this technology from the trial site. The scientific study was the subject of a separate report. In this article, we report on a cost and benefit analysis of installing a pergola on a case study farm. The key message from this analysis is that installing a pergola over a table grape property is worth investigating while there is a price premium for the fruit produced.
title: Helikal-chirale Poly(isocyanide) als asymmetrische Katalysatoren
Creators: name: Fleckenstein, Max

Year: 2021

description: Diese Dissertation ist in drei Teilprojekte gegliedert. Der Hauptteil der Arbeit beschäftigt sich mit der Etablierung von phosphanylierten Poly(isocyaniden) in der asymmetrischen Katalyse. Dabei wurden verschiedene Monomerstrukturen hergestellt, die Schwefel als Schutzgruppe für die sauerstofflabilen Phosphane verwenden. Diese Phosphorsulfide wurden zu hochmolekularen Poly(isocyaniden) umgesetzt, entschützt und durch Komplexierung mit Übergangsmetallen der asymmetrischen Katalyse zugänglich gemacht. Hierbei konnten Enantiomerenüberschüsse bis zu 60% erzielt werden. Daneben wurden Labelstrukturen für die Hyperpolarisations-NMR-Spektroskopie entwickelt und an ein Modellpeptid angebunden. Die Güte der Labelbausteine wurde anschließend mittels DNP- und PHIP-NMR-Spektroskopie überprüft. Der dritte Teil der Dissertation beschäftigt sich mit der Entwicklung von Sulfonimidamiden, die als Schutzgruppe für Aminogruppen fungieren können.

description: Este trabajo evalúa la importancia que tiene el cultivo del tabaco en América Latina. Con este fin se analizan las principales variables del sector como son la cantidad y el valor de la producción, el número de hectáreas cultivadas y el rendimiento de los cultivos. También se estudia el valor del sector como fuerza exportadora. Se construye además, a partir de diferentes fuentes, un comparativo del empleo directo que genera el cultivo del tabaco en los países tabacaleros de América Latina. Los resultados muestran que la producción de los países latinoamericanos en conjunto ha venido aumentando en los últimos años, haciendo que la participación de la producción de este continente sea cercana al 16% de la producción mundial. Argentina y Brasil destacan por su producción al situarse entre los diez mayores productores del mundo. La extensión de área cultivada en la región alcanza el 13,55% del área dedicada de tabaco en el mundo. El incremento en la producción ha impulsado un crecimiento en la productividad del mismo con una tendencia creciente desde hace ya varios lustros. Este comportamiento positivo se ha visto acompañado de un aumento en los precios al productor, particularmente desde 2007. Es pues un sector con impacto significativo en la región. El cultivo de tabaco tiene la capacidad de generar 650.000 empleos directos y exportar US$ 3.788 millones de dólares anuales. Considerando que sólo se involucra empleos directos en el análisis estas cifras son muy significativas.
Nonequilibrium fluctuations in a resistor

description: In small systems where relevant energies are comparable to thermal agitation, fluctuations are of the order of average values. In systems in thermodynamical equilibrium, the variance of these fluctuations can be related to the dissipation constant in the system, exploiting the Fluctuation-Dissipation Theorem (FDT). In non-equilibrium steady systems, Fluctuations Theorems (FT) additionally describe symmetry properties of the probability density functions (PDFs) of the fluctuations of injected and dissipated energies. We experimentally probe a model system: an electrical dipole driven out of equilibrium by a small constant current $I$, and show that FT are experimentally accessible and valid. Furthermore, we stress that FT can be used to measure the dissipated power $\bar{\cal P}=RI^2$ in the system by just studying the PDFs symmetries.

description: The description of the collective magnetorheological effect induced by magnetic field in magnetoactive elastomers is proposed. The condition of consistency is used between magnetic and mechanic momenta of forces exerted on magnetically uniaxial ferromagnetic particles in elastomer at their magnetization. The study shows that even in the case of small concentration of particles, the value of magnetically-induced shear can be anomalously large, reaching up to tens of percent. The deformation of magnetoactive elastomer can evolve critically, as a second-order phase transition, if magnetic field is aligned along the easy axis of particles.

description: This essay analyzes the member participation in general as-sembly and educational committees in agricultural cooperatives in func-tion of economic objective function, members’ number, and economic performance. There are analyses of two regression models that show the participation is an inverse function of economic performance in coopera-tives and the educational committee participation occurs in functions to intensify the member relations in cooperative with problems with mem-ber economic activity. At the end it is possible also indicate that member participation is important to corporate governance transparency in agri-cultural cooperative but there is a dichotomy because the best economic performance in cooperatives could not incentive member participation and in consequence the governance transparency that needs additional costs to correct this deficiency.

description: The impact parameter is one of the crucial physical quantities of heavy-ion collisions (HICs), and can affect obviously many observables at the final state, such as the multifragmentation and the collective flow. Usually, it cannot be measured directly in experiments but might be inferred from observables at the final state. Artificial intelligence has had great success in learning complex representations of data, which enables novel modeling and data processing approaches in physical sciences. In this article, we employ two of commonly used algorithms in the field of artificial intelligence, the Convolutional Neural Networks (CNN) and Light Gradient Boosting Machine (LightGBM), to improve the accuracy of determining impact parameter by analyzing the proton spectra in transverse momentum and rapidity on the event-by-event basis. Au+Au collisions with the impact parameter of 0$\leq$$b$$\leq$10 fm at intermediate energies ($E_{\rm lab}$=$0.2$-$1.0$ GeV$/$nucleon) are simulated with the ultrarelativistic quantum molecular dynamics (UrQMD) model to generate the proton spectra data. It is found that the average difference between the true impact parameter and the estimated one can be smaller than 0.1 fm. The LightGBM algorithm shows an improved performance with respect to the CNN on the task in this work. By using the LightGBM's visualization algorithm, one can obtain the important feature map of the distribution of transverse momentum and rapidity, which may be helpful in inferring the impact parameter or centrality in heavy-ion experiments.

description: For decades, the Brazilian agriculture sector has suffered strong income transfers to many of the country’s other economic sectors, which caused the impoverishment of many Brazilian farmers. Govern-ment sponsored rural credit assistance programs have somewhat redres-sed this inequity and ameliorated the farmer’s plight. However, due to the structure of these credit assistance programs, the majority of their benefits have gone to the country’s largest agricultural producers, there-by increasing income disparity found between family and commercial farms. New policies are needed that actually assist the majority of those that work in the Brazilian agriculture sector: the family farmers. This work evaluates effects of implementation of an Income Stabilization Policy (ISP) intended to support family farmers, focusing on cassava, milk, and bean producers. The evaluation is based on the costs and benefits of ISP, with reference to the theory of economic surplus. This article also considers the policy’s negative effect on the surplus gene-rated by commercial producers. Study results indicate that implemen-tation of the proposed ISP would increase the prices received for cassa-va, milk and beans, improve the income of Brazilian family farmers producing these products, and lead to consumer gains that more than offset the losses suffered by large, commercial agriculture producers.

description: Shear banding is an important deformation and failure mechanism in metallic systems, especially at high-rate straining. Dynamic recrystallization was often reported to account for the refined microstructure of shear bands but rarely confirmed using direct quantitative measurement. Here, we employ quantitative precession electron diffraction analysis to uncover shear band microstructure in pure titanium. The results reveal that the microstructure is dominated by early stages of grain subdivision process. Dynamic recrystallization is not as prevalent as perceived conventionally. Our results offer key insights into understanding shear banding and highlight the need for quantitative analyses of shear band microstructure. A critical quantitative assessment of shear band microstructures is made using precession beam diffraction imaging. Specifically, grain subdivision, as opposed to dynamic recrystallization, drives the shear band microstructure evolution.

description: I review work on diffractive vector meson production in photon-proton collisions at high energy and large momentum transfer, accompanied by proton dissociation and a large rapidity gap. This process provides a test of the high energy scattering dynamics, but is also sensitive to the details of the treatment of the vector meson vertex. The emphasis is on the description of the process by a solution of the non-forward BFKL equation, i.e. the equation describing the evolution of scattering amplitudes in the high-energy limit of QCD. The formation of the vector meson and the non-perturbative modeling needed is also briefly discussed.

Energy flux and dissipation of inhomogeneous plane waves in hereditary viscoelasticity

description: Inhomogeneous small-amplitude plane waves of (complex) frequency $ω$ are propagated through a linear dissipative material which displays hereditary viscoelasticity. The energy density, energy flux and dissipation are quadratic in the small quantities, namely, the displacement gradient, velocity and velocity gradient, each harmonic with frequency $ω$, and so give rise to attenuated constant terms as well as to inhomogeneous plane waves of frequency $2ω$. The quadratic terms are usually removed by time averaging but we retain them here as they are of comparable magnitude with the time-averaged quantities of frequency $ω$. A new relationship is derived in hereditary viscoelasticity that connects the amplitudes of the terms of the energy density, energy flux and dissipation that have frequency $2ω$. It is shown that the complex group velocity is related to the amplitudes of the terms with frequency $2ω$ rather than to the attenuated constant terms as it is for homogeneous waves in conservative materials.

He was awarded the Distinguished Conduct Medal but for what is not clear as the event is missing from the regimental diary. Tom Booth was presented with a 'chalice' from St Ann's in recognition of him winning the DCM and is dated 25th August 1918. A piece appeared in the London Gazette describing how he was surrounded by the enemy (see photos) - this is not necessarily why he was awarded DCM. He was hospitalised on 27th September 1918 by a gunshot wound to the clavicle and was in hospital in Glasgow. He was demobilised in 1920. Tom didn't speak about his war service during his lifetime. His grandson found the medal and did some research.

description: The biotechnology reached the principal link of the soy complex, that is, the producers. The GMO soybean promotes the reduction of the necessary amount of herbicide and the cost of production. The objective of this study was to determine and compare the average costs incurred into the production of conventional and the new technology for the South Mato Grosso State of the harvest 2004/05, through primary data, obtained for field research. In the present work it is presented the methodology adopted for the formation of the data base and for the countable structure properly said. Through the analysis of the data base it was possible to observe that the cost of the GMO is approximately 14.8% less than the conventional one.

description: The motion of an elastic solid inside of an incompressible viscous fluid is ubiquitous in nature. Mathematically, such motion is described by a PDE system that couples the parabolic and hyperbolic phases, the latter inducing a loss of regularity which has left the basic question of existence open until now. In this paper, we prove the existence and uniqueness of such motions (locally in time), when the elastic solid is the linear Kirchhoff elastic material. The solution is found using a topological fixed-point theorem that requires the analysis of a linear problem consisting of the coupling between the time-dependent Navier-Stokes equations set in Lagrangian variables and the linear equations of elastodynamics, for which we prove the existence of a unique weak solution. We then establish the regularity of the weak solution; this regularity is obtained in function spaces that scale in a hyperbolic fashion in both the fluid and solid phases. Our functional framework is optimal, and provides the a priori estimates necessary for us to employ our fixed-point procedure.

description: In this review I give an overview on the conceptual issues involved in the question how to interpret so-called `direct top quark mass measurements', which are based on the kinematic reconstruction of top quark decay products at the Large Hadron Collider (LHC). These measurements quote the top mass parameter $m_t^{\rm MC}$ of Monte-Carlo event generators with current uncertainties of around $0.5$ GeV. At present time the problem of finding a rigorous relation between $m_t^{\rm MC}$ and top mass renormalization schemes defined in field theory is unresolved and touches perturbative as well as nonperturbative aspects and the limitations of state-of-the-art Monte-Carlo event generators. I review the status of LHC top mass measurements, illustrate how conceptual limitations enter and explain a controversy that has permeated the community in the context of the interpretation problem. Recent advances in acquiring first principle insights are summarized, and it is outlined what else has to be understood to fully resolve the issue. For the time being, I give a recommendation how to deal with the interpretation problem when making top mass dependent theoretical predictions.

description: Lightweight magnesium alloys with good thermal conductance are in demand for structural components in portable devices. This work presents a strategy to achieve excellent thermal conductivity, room temperature (RT) formability and high strength in magnesium sheet alloys. We found that a Mg-1.6Zn-0.5Ca-0.4Zr alloy shows a substantial increase in thermal conductivity to over 130 W/(m·K) due to the reduced supersaturation of solute atoms in the matrix by the precipitation of Guinier-Preston (G.P.) zones while exhibiting excellent RT formability with a large Index Erichsen value of 8.1 mm, and a high yield strength of 227 MPa by peak aging treatment. This work reports a superiority of heat treatable magnesium alloy in simultaneously achieving high thermal conductivity and excellent mechanical properties through quantitative analysis of the microstructure in atomic scale.

description: Over the last decade, some two hundred municipalities in the state of São Paulo increased the area of Atlantic Forest, and since most of them are adjacent areas they are starting to show up as authentic spots of recovering forests on the map of the State. The present article seeks to identify the major factors underpinning this unprecedented increase. The initial premise was that the recovery of the Atlantic Fo-rest was associated with the increasing number of ventures protecting natural heritage and promoting its economic exploitation. The study shows that compliance with the legislation, resulting from enhanced enforcement, along with a reduction in farming and livestock-breeding activities that allowed the natural growth of the vegetation, were the main drivers of the recovery of the Atlantic Forest over the last decade. However, as initially assumed, a rare combination of private enterprise and forest conservation can be witnessed in some areas of São Paulo State. This synergy has not arisen by chance; it mainly depends on the existence of institutional agreements among public and private players committed to the conservation of the natural heritage.

We conclude with the unique decomposition in distribution of stationary stable processes into the sum of four major independent components: 1. A mixed moving average component. 2. A harmonizable (or ``trivial'') component. 3. A cyclic component 4. A component which is different from these.

description: This article reports the results of a research about the sustai-nability of extractive farmers in the Atlantic slopes of Rio Grande do Sul. The extractive economy at issue is related to a species usually known as leather fern (Rumohra adiantiformis (G.Forest.) Ching). It is estimated that 3,000 families in the region perform this non-regulated activity, whi-ch is their only source of income. The sustainability degree of farmers was calculated from information related to environmental, social and eco-nomic dimensions, and to productivity, stability, equity, resilience, and autonomy criteria. The analysis focused on the comparison among the In-dexes Related to Dimension (IRD), Criteria (IRC) and Sustainability (IRS) of each kind of production system. The results pointed to the existence of four kinds of production systems, and three of them were included in this research. The sustainability indexes showed that the production system type 3 was the most sustainable, followed by type 2 and, ﬁ nally, type 1.

Creators: name: Dajani, Muna Daoud
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2018

description: This thesis is concerned with the political subjectivity of farming in settler colonial contexts. Guided by theoretical concepts of political ecology, settler colonialism and lived geographies, this thesis examines two farming communities which have been central to the realisation of Israeli settler colonial hydro-imaginaries and realities. It employs a historical approach to explain the realities facing these communities today, in their struggle over water to maintain their farming livelihood and hence how, through water, claims of recognition are shaped and developed. Employing mixed qualitative methods of ethnography, archival research, interviews and participant observation, this thesis posits that farming practices, including demands for water and infrastructure, acquire political subjectivity in both communities, transcending farming into an act of resistance, sumud (steadfastness) and rootedness. Under conditions of settler colonial rule, communities are faced with a dialectical presence-absence of the state in their lives. The settler colonial water and land policies materialised realities of unequal geographies and waterscapes, othering the communities concerned through policies of difference and enactment of misrecognition through uprooting land-based belonging and resource rights. Through analysis of their acts of protest through the lens of ‘presence-absence’, farmers demand for water and infrastructure have re-configured from being acts of resistance to a scaled-up articulation for their demands for recognition, inclusion and development. Examining the role of sumud as a form of resistance in livelihood practices highlights how access to, and control over, flows of water by indigenous Arab communities acquire material and symbolic weight as an articulation of rootedness and protest the Israeli hydraulic mission of centralised water control and exclusion. Hence, their realities are shaped by complex conditions of settler colonial rule, where farming acquires political subjectivity as it enacts sumud in their everyday practices.

description: In this paper, we investigate the cosmic anisotropy from the SN-Q sample, consisting of the Pantheon sample and quasars, by employing the hemisphere comparison (HC) method and the dipole fitting (DF) method. Compared to the Pantheon sample, the new sample has a larger redshift range, a more homogeneous distribution, and a larger sample size. For the HC method, we find that the maximum anisotropy level is $AL_{max}=0.142\pm0.026$ in the direction ($l$, $b$) = $({316.08^{\circ}}^{+27.41}_{-129.48}$, ${4.53^{\circ}}^{+26.29}_{-64.06})$. The magnitude of anisotropy is $A$ = ($-$8.46 $^{+4.34}_{-5.51}$)$\times$$10^{-4}$ and the corresponding preferred direction points toward $(l$, $b)$ = ($29.31^{\circ}$$^{+30.59}_{-30.54}$, $71.40^{\circ}$$^{+9.79}_{-9.72}$) for the quasar sample from the DF method. The combined SN and quasar sample is consistent with the isotropy hypothesis. The distribution of the dataset might impact the preferred direction from the dipole results. The result is weakly dependent on the redshift from the redshift tomography analysis. There is no evidence of cosmic anisotropy in the SN-Q sample. Though some results obtained from the quasar sample are not consistent with the standard cosmological model, we still do not find any distinct evidence of cosmic anisotropy in the SN-Q sample.

description: Using an algebraic formulation, we explore two well-known degeneracies involving the mass-squared differences for three-neutrino oscillations assuming CP symmetry is conserved. For vacuum oscillation, we derive the expression for the mixing angles that permit invariance under the interchange of two mass-squared differences. This symmetry is most easily expressed in terms of an ascending mass order. This can be used to reduce the parameter space by one half in the absence of the MSW effect. For oscillations in matter, we derive within our formalism the known approximate degeneracy between the standard and inverted mass hierarchies in the limit of vanishing $θ_{13}$. This is done with a mass ordering that permits the map $Δ_{31} \mapsto -Δ_{31}$. Our techniques allow us to translate mixing angles in this mass order convention into their values for the ascending order convention. Using this dictionary, we demonstrate that the vacuum symmetry and the approximate symmetry invoked for oscillations in matter are distinctly different.

description: We consider the circumnuclear regions of MaNGA galaxies. The spectra are classified as AGN-like, HII-region-like (or SF-like), and intermediate (INT) spectra according to their positions on the BPT diagram. There are the following four configurations of the radiation distributions in the circumnuclear regions: 1) AGN+INT, the innermost region of the AGN-like radiation is surrounded by a ring of radiation of the intermediate type; 2) INT, the central area of radiation of the intermediate type; 3) SF+INT, the inner region of the HII-region-like radiation is surrounded by a ring of radiation of the intermediate type; and 4) SF, the HII-region-like radiation only. The LINERS of configurations 1 and 2 are examined. The spaxel spectra of the LINERs form a sequences on the BPT diagram. The line ratios change smoothly with radius, from AGN-like at the center to HII-region-like at larger distances. This is in agreement with the paradigm that the LINERs are excited by AGN activity. The AGN and INT radiation in the circumnuclear region is accompanied by an enhanced gas velocity dispersion, s_g. The radius of the area of the AGN and INT radiation is similar to the radius of the area with enhanced s_g, and the central s_g,c correlates with the luminosity of the AGN+INT area. We assume that the gas velocity dispersion can serve as an indicator of the AGN activity. The values of s_g,c for the SF-type centers partly overlap with those of the AGN-type centers. We find that there is a demarcation line between the positions of the AGN-type and SF-type objects on the s_g,c - central Halpha surface brightness diagram.

Forest fire occurrence outside the historic range of frequency and intensity can result in extensive economic and ecological impacts. The detection of regional patterns of fire occurrence density can allow for the identification of areas at greatest risk of significant impact and for the selection of locations for more intensive analysis. In 2017, the number of satellite-detected forest fire occurrences recorded for the conterminous States was the fifth most in 17 full years of data collection and the most since 2014. Ecoregion sections in the Pacific Northwest, the northern Rocky Mountains, and California had the highest forest fire occurrence density per 100 km2 of forested area. Geographic hot spots of high fire occurrence density were detected in these same areas, as well as in the Southeast and southern Arizona. Ecoregion sections in southern, central, and northern California; the Cascade Mountains of Oregon and Washington; and northern Idaho and northwestern Montana experienced greater fire occurrence density than normal compared to the previous 15-year mean and accounting for variability over time. Alaska experienced low fire occurrence densities except in one northeastern ecoregion section. The Big Island of Hawai‘i experienced a lower fire occurrence density than in recent years as a result of an ongoing volcanic eruption.

description: We perform short-time Monte Carlo simulations to study the criticality of the isotropic two-state majority-vote model on cubic lattices of volume $N = L^3$, with $L$ up to $2048$. We obtain the precise location of the critical point by examining the scaling properties of a new auxiliary function $Ψ$. We perform finite-time scaling analysis to accurately calculate the whole set of critical exponents, including the dynamical critical exponent $z=2.027(9)$, and the initial slip exponent $θ= 0.1081(1)$. Our results indicate that the majority-vote model in three dimensions belongs to the same universality class of the three-dimensional Ising model.

description: In this letter, we develop a mode-coupling theory for a class of nonlinear Langevin equations with multiplicative noise using a field theoretic formalism. These equations are simplified models of realistic colloidal suspensions. We prove that the derived equations are consistent with the fluctuation-dissipation theorem. We also discuss the generalization of the result given here to real fluids, and the possible description of supercooled fluids in the aging regime. We demonstrate that the standard idealized mode-coupling theory is not consistent with the FDT in a strict field theoretic sense.

description: Expected utility maximization problems in mathematical finance lead to a generalization of the classical definition of entropy. It is demonstrated that a necessary and sufficient condition for the second law of thermodynamics to operate is that any one of the generalized entropies should tend to its minimum value of zero.

description: La valoración económica tradicional (VE) se ha constituido en una herramienta fundamental para apoyar el establecimiento de áreas marinas protegidas como la estrategia preferida para la conservación de los ecosistemas marinos y costeros y de los servicios que éstos proveen. Sin embargo, generalmente, estos ejercicios estiman los beneficios que la conservación genera a actores situados fuera de las mismas, quienes no hacen uso extractivo de los recursos como su principal fuente de alimento e ingresos, y han ignorado los valores que las comunidades locales otorgan a los ecosistemas que las rodean, o los costos de oportunidad que las comunidades locales, usuarias de recursos, asumen cuando deben enfrentar las restricciones que imponen las AMPs en el acceso a los recursos. Adicionalmente, se ha cuestionado la pertinencia de realizar VE en contextos locales porque su implementación aún enfrenta desafíos prácticos, metodológicos, éticos y políticos. Siguiendo las recomendaciones de The Economics of Ecosystems and Biodiversity (TEEB), este estudio propone una metodología de valoración económica que es innovadora, porque combina herramientas cualitativas de valoración que permiten capturar la importancia relativa que los usuarios locales otorgan a los ecosistemas, y a los diversos servicios que proveen, con herramientas cuantitativas estándares de la VE, experimentos de elección, que permiten capturar la disponibilidad a aceptar restricciones en el uso de recursos impuestas por el establecimiento de AMPs. La metodología propuesta incorpora enfoques de valoración colectiva y deliberación grupal, en donde la construcción participativa de los escenarios de base y de cambio permite un mejor entendimiento, por parte de los usuarios de recursos, de la situación hipotética a valorar.
Detecting domain wall trapping and motion at a constriction in narrow ferromagnetic wires using perpendicular-current giant magnetoresistance

description: We present a versatile method for detecting the presence and motion of a trapped domain wall in a narrow ferromagnetic layer using current-perpendicular-to-plane (CPP) giant magnetoresistance (MR). The CPP-MR response to small motions of the trapped domain wall is enhanced because the CPP current is restricted to the region of wall trapping. We use a Permalloy/Cu/Permalloy spin valve in the shape of a long, ~500-nm-wide wire with a constriction (notch) near its middle that acts as a trapping site for a head-to-head domain wall. Two different notch shapes were studied, mostly at 4.2 K but also at 295K.
