description: A rendszeres mezőgazdasági adatgyűjtések közel kétszáz éves múltra tekintenek vissza. Az 1828-tól végrehajtott felmérések a földhasználatra, növénytermelésre és az állattartásra terjedtek ki, az első „földhasználati regisztert” – az ideiglenes föld¬katasztert – 1853-ban állították fel. A szőlőterületekre, borászatra vonatkozó első statisztikát Magyarország – nemzetközi felkérésre – 1873-ban dolgozta ki, illetve hajtotta végre. A 19. század végére már Európa-szerte egyre nagyobb igény merült fel a mezőgazdasági tevékenység, a mezőgazdasági termelés részletesebb megismerésére. Az első magyar – általános – mezőgazdasági cenzus rendszerét Keleti Károly, az önálló magyar statisztikai hivatal első elnöke személyes vezetésével dolgozták ki. A nagy volumenű munka végrehajtására csak Keleti Károly halála után – 1895-ben – kerülhetett sor, mert a cenzus végrehajtása forrásainak megteremtése nagy nehé¬zségekbe ütközött. Az EU rendeletének megfelelően 2010-ben teljes körű mezőgazdasági összeírásra, majd 2013-ban és 2016-ban reprezentatív mezőgazdasági össze¬írásra kerül sor. ---------------------------------------------------- Regular collection of agricultural information goes back to nearly two hundred years. The surveys, which began in 1828, addressed land use, crop cultivation and animal husbandry. The first ‘land use register’ – a temporary cadastre – was set up in 1853. The first Hungarian statistics for viticulture and winemaking were created in 1873 upon international request. By the end of the 19th century, the need to obtain more detailed information about agricultural activities and agricultural production had grown substantially. The methodology for the first general agricultural census in Hungary was developed under the personal supervision of Károly Keleti, the first head of the first independent Hungarian Statistical Office. This ambitious job could only be completed after his death, in 1895, because of the great difficulties of obtaining funding for its implementation.

Ices in the edge-on disk CRBR 2422.8-3423: Spitzer spectroscopy and Monte Carlo radiative transfer modeling

description: We present 5.2-37.2 micron spectroscopy of the edge-on circumstellar disk CRBR 2422.8-3423 obtained using the InfraRed Spectrograph (IRS) of the Spitzer Space Telescope. The IRS spectrum is combined with ground-based 3-5 micron spectroscopy to obtain a complete inventory of solid state material present along the line of sight toward the source. We model the object with a 2D axisymmetric (effectively 3D) Monte Carlo radiative transfer code. It is found that the model disk, assuming a standard flaring structure, is too warm to contain the very large observed column density of pure CO ice, but is possibly responsible for up to 50% of the water, CO2 and minor ice species. In particular the 6.85 micron band, tentatively due to NH4+, exhibits a prominent red wing, indicating a significant contribution from warm ice in the disk. It is argued that the pure CO ice is located in the dense core Oph-F in front of the source seen in the submillimeter imaging, with the CO gas in the core highly depleted. The model is used to predict which circumstances are most favourable for direct observations of ices in edge-on circumstellar disks. Ice bands will in general be deepest for inclinations similar to the disk opening angle, i.e. ~70 degrees. Due to the high optical depths of typical disk mid-planes, ice absorption bands will often probe warmer ice located in the upper layers of nearly edge-on disks. The ratios between different ice bands are found to vary by up to an order of magnitude depending on disk inclination due to radiative transfer effects caused by the 2D structure of the disk. Ratios between ice bands of the same species can therefore be used to constrain the location of the ices in a circumstellar disk. [Abstract abridged]

Characterization of arsenic in a tailings impoundment under post depositional conditions
Creators: name: Meilleur, Desiree
Publisher: name: University of British Columbia
Year: 2009

description: Arsenic is found naturally in the gold ores extracted from the Red Lake Mine in Balmertown, Ontario. Milling of ores produced arsenic-rich tailings that have been disposed of in different locations around the site through the over 50 years of mine operations. The composition of the tailings depended upon the mineral processing methods (cyanidation, sulphide flotation, and roasting) used at the time. The primary objective of this thesis was to characterize the forms, stability, and mobility of arsenic in the different wastes located around the mine site. In addition, a potential method to reduce arsenic transport from tailings pond sediments into the overlying pond waters was investigated. Whole rock analysis, Scanning Electron Microscopy (SEM), Rietveld refined powder X-ray diffraction, sequential extractions, and X-ray Absorption Near Edge Structure (XANES) using a Synchrotron light source were used to mineralogically characterize the various tailings types. Experiments were conducted to investigate the behaviour of arsenic in several tailings types under various conditions with the objective of determining if arsenic could be stabilized under reducing conditions, ideally in the form of arsenopyrite or arsenian pyrite. High aqueous arsenic concentrations were found to be associated with oxidized arsenic bearing mineral phases (i.e. arsenic bearing iron oxyhydroxides contained in historical roaster-derived tailings and tailings pond sediments). Mobilization of a significant fraction of the arsenic contained within these wastes is likely to continue as a result of the reducing conditions that these wastes are stored under. Arsenic is found at relatively low concentrations in the freshly produced tailings, primarily in the form of arsenopyrite, and is likely to remain immobile as long as saturated conditions exist. In order to minimize arsenic mobilization from solid wastes, oxidized arsenic bearing phases (e.g. arsenic bearing iron oxyhydroxides) should be kept dry and dissolved organic carbon influxes should be limited. Reduced arsenic bearing mineral phases (e.g. arsenopyrite, arsenian pyrite), however, should be maintained under saturated conditions. During field and laboratory experiments it appears as if arsenic was immobilized as a reduced sulphide phase under strongly reducing conditions, however further work is required to determine the mechanism and stability of the produced phase.
Quantum Oscillation and Landau-Zener transition in Untilted Nodal line semimetals under a time-periodic magnetic field

description: Nodal line semimetals (NLSM) exhibit interesting quantum oscillation characteristics when acted upon by a strong magnetic field. We study the combined effect of strong direct (dc) and alternating (ac) magnetic field, perpendicular to the nodal plane in an untilted NLSM in order to probe the behavior of the low lying Landau level (LL) states that can periodically become gapless for suitably chosen field parameters. The oscillatory field variation, as opposed to a steady one, has interesting impact on the quantum oscillation phenomena with the Landau tubes crossing the Fermi surface extremally two times per cycle. Furthermore, the low energy modes can witness Landau-Zener like transitions between valence and conduction band providing further routes to conduction. We discuss such transition phenomena following the framework of adiabatic-impulse approximation for slow quenches. Next we also investigate the effect of oscillating magnetic field acting parallel to the nodal loop where topologically nontrivial magnetic oscillations at low energies can be witnessed. Therefore, with proper parameters chosen, one can engineer topological transitions to occur periodically in such systems as the oscillating field is swept through its cycles.

description: We present the first X-ray observation of an oscillation during a stellar flare. The flare occurred on the active M-type dwarf AT Mic and was observed with XMM-Newton. The soft X-ray light curve (0.2-12 keV) is investigated with wavelet analysis. The flare's extended, flat peak shows clear evidence for a damped oscillation with a period of around 750 s, an exponential damping time of around 2000 s, and an initial, relative peak-to-peak amplitude of around 15%. We suggest that the oscillation is a standing magneto-acoustic wave tied to the flare loop, and find that the most likely interpretation is a longitudinal, slow-mode wave, with a resulting loop length of (2.5 +- 0.2) e10 cm. The local magnetic field strength is found to be (105 +- 50) G. These values are consistent with (oscillation-independent) flare cooling time models and pressure balance scaling laws. Such a flare oscillation provides an excellent opportunity to obtain coronal properties like the size of a flare loop or the local magnetic field strength for the otherwise spatially-unresolved star.

description: Földviszonyainkat 20 éve a nemzetek feletti tőkehasznosulás elsajátítási magánérdekét érvényesítő, neoliberális birtokpolitika uralja. Ez – rendszertani lényegéből eredően – maga alá gyűrte a földnek a társadalmi közösséget fenntartó és újratermelő közfunkcióit. Az új történelmi korszakban – amely a civilizáció összeomlásával is fenyeget – a föld és a víz, mint természeti őselemek birtoklása a túlélés feltétele. Ezért létkérdés a haszonelvű birtokpolitikának a közérdekű, értékkövető földpolitikával való felváltása. Amikor a közérdeknek elkötelezett agrárértelmiség a nemzeti önvédelem eszköztárával keres kitörési pontot az értékalapú, a közjót és a fenntarthatóságot szolgáló birtokpolitikához, még a szakmai párbeszéd igényénél is gátakba ütközik. Az alapfogalmak tisztázásra szorulnak, csak ezután épülhet fel – társadalmi közmegegyezéssel – a közérdekű birtokpolitika cél- és intézményrendszere. Jelen írásom ehhez próbál szerény adalékot adni, részben néhány fogalom megvilágításával, részben az általam kidolgozott, nemzeti földprogram felvázolásával. -------------------------------------------------- For 20 years, land ownership in Hungary has been dominated by neoliberal land policy, which serves the private interests of cross-national capital investment. By its very nature, this policy has suppressed the community functions of land, such as its ability to sustain and recreate societies and communities. In the new era of history – which might even bring about the collapsing of civilisations – ownership of soil and water, these two ancient natural elements, is essential to survival. This is why replacing profit-oriented land policy with a value-oriented land policy serving common interests is indispensable. When agricultural intellectuals desiring to use the means of national self-defence to seek a point of breakthrough that will bring about a value-based land policy in the service of sustainability and the public good, even professional dialogue is hampered. Basic terms need to be clarified before the goals and institutions of a land policy based on our common interests can be set up, based on a nation-wide agreement. This paper intends to offer a humble contribution to this process by clarifying some terms and by outlining a national land scheme I have developed.

description: Megkülönböztetve egymástól a KAP és a birtokpolitikára vonatkozó közösségi jogi rendelkezéseket, arra a következtetésre jutok, hogy túlzás, illetve nem helytálló Tanka Endre megállapítása, mely szerint az uniós jog a birtokpolitikában „maga a politika”, „a tagállami jogalkotás annak végrehajtására szűkül”, és a birtokpolitikában a közösségi jog „a belső jogot csaknem kiszorítja”, hiszen a tagállam dönthet úgy, hogy semmilyen korlátozást nem léptet életbe a földpiacon, valamint a közösségi joggal összeegyeztetett igen szigorú, Tanka Endre szavaival élve értékalapú birtokpolitikát, polgári demokratikus földreformot is bevezethet. Alapelv szerint a birtokpolitikában a tőke szabad mozgásának korlátozása tilos – minden tagállam esetében –, de az Európai Bíróság által elismert közérdekből, az arányosság és a szükségesség jogelvének betartásával mégis korlátozható, feltéve, hogy az adott rendelkezések nem a más tagállamok polgárainak hátrányos megkülönböztetésére irányulnak. A földkérdésben véleményem szerint nem vezet előre a nemzeti szuverenitás kontra közösségi jog problematika előtérbe helyezése, megoldás inkább attól várható, hogy megvizsgálják azt, hogy milyen, a közösségi joggal összeegyeztethető szabályozással lehet a célokat megvalósítani. ------------------------------------------ Making a distinction between Community law provisions on CAP and on land policy, I conclude that the observations by Endre Tanka, such as the Union law on land policy being “policy itself”, that “legislation in the Member States is limited to the implementation thereof”, and that Community law “nearly precludes any national legislation” on land policy, are exaggerated or incorrect, as Member States may choose not to apply any restriction to the land market, or may even choose to introduce a very strict land policy – to quote Endre Tanka, a value-based land policy, or a democratic land reform. In principle, the free movement of capital may not be restricted under land policy – in any Member State –, but restrictions may still be introduced if they serve public interests accepted by the European Court of Justice and are in line with the legal principles of proportionality and adequacy, provided that such provisions are not intended to discriminate against citizens of the other Member States. In my opinion, focusing on the issue of national sovereignty versus Community law will not bring us closer to a solution. It would be more useful to look into potential regulations which are compatible with Community law and would still help attain the desired goals.

description: Wilson loop averages are evaluated for large contours and in the large N limit by means of minimal surfaces. This allows the study of the quark-antiquark gauge invariant Green function through its dependence on Wilson loops. A covariant bound state equation is derived which in the center-of-mass frame and at equal-times takes the form of a Breit-Salpeter type equation. The interaction potentials reduce in the static case to a confining linear vector potential. For moving quarks, flux tube like contributions are present. The nonrelativistic limit is considered.

description: The field of Artificial Intelligence (AI) and, in particular, the Machine Learning area, counts on a wide range of performance metrics and benchmark data sets to assess the problem-solving effectiveness of its solutions. However, the appearance of research centres, projects or institutions addressing AI solutions from a multidisciplinary and multi-stakeholder perspective suggests a new approach to assessment comprising ethical guidelines, reports or tools and frameworks to help both academia and business to move towards a responsible conceptualisation of AI. They all highlight the relevance of three key aspects: (i) enhancing cooperation among the different stakeholders involved in the design, deployment and use of AI; (ii) promoting multidisciplinary dialogue, including different domains of expertise in this process; and (iii) fostering public engagement to maximise a trusted relation with new technologies and practitioners. In this paper, we introduce the Observatory on Society and Artificial Intelligence (OSAI), an initiative grew out of the project AI4EU aimed at stimulating reflection on a broad spectrum of issues of AI (ethical, legal, social, economic and cultural). In particular, we describe our work in progress around OSAI and suggest how this and similar initiatives can promote a wider appraisal of progress in AI. This will give us the opportunity to present our vision and our modus operandi to enhance the implementation of these three fundamental dimensions.

description: Control of impurity concentrations in semiconducting materials is essential to device technology. Because of their intrinsic confinement, the properties of two-dimensional semiconductors such as transition metal dichalcogenides (TMDs) are more sensitive to defects than traditional bulk materials. The technological adoption of TMDs is dependent on the mitigation of deleterious defects and guided incorporation of functional foreign atoms. The first step towards impurity control is the identification of defects and assessment of their electronic properties. Here, we present a comprehensive study of point defects in monolayer tungsten disulfide (WS$_2$) grown by chemical vapor deposition (CVD) using scanning tunneling microscopy/spectroscopy, CO-tip noncontact atomic force microscopy, Kelvin probe force spectroscopy, density functional theory, and tight-binding calculations. We observe four different substitutional defects: chromium (Cr$_{\text{W}}$) and molybdenum (Mo$_{\text{W}}$) at a tungsten site, oxygen at sulfur sites in both bottom and top layers (O$_{\text{S}}$ top/bottom), as well as two negatively charged defects (CDs). Their electronic fingerprints unambiguously corroborate the defect assignment and reveal the presence or absence of in-gap defect states. The important role of charge localization, spin-orbit coupling, and strain for the formation of deep defect states observed at substitutional defects in WS$_2$ as reported here will guide future efforts of targeted defect engineering and doping of TMDs.

An Observationally Motivated Framework for AGN Heating of Cluster Cores

Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The cooling-flow problem is a long-standing puzzle that has received considerable recent attention, in part because the mechanism that quenches cooling flows in galaxy clusters is likely to be the same mechanism that sharply truncates the high end of the galaxy luminosity function. Most of the recent models for halting cooling in clusters have focused on AGN heating, but the actual heating mechanism has remained mysterious. Here we present a framework for AGN heating derived from a Chandra survey of gas entropy profiles within cluster cores. This set of observations strongly suggests that the inner parts of cluster cores are shock-heated every ~10^8 years by intermittent AGN outbursts, driven by a kinetic power output of ~ 10^45 erg/sec and lasting at least 10^7 years. Beyond ~30 kpc these shocks decay to sound waves, releasing buoyant bubbles that heat the core's outer parts. Between heating episodes, cooling causes the core to relax toward an asymptotic pure-cooling profile. The density distribution in this asymptotic profile is sufficiently peaked that the AGN shock does not cause a core entropy inversion, allowing the cluster core to retain a strong iron abundance gradient, as observed.

description: In this paper, we analyze static traversable wormholes via Noether symmetry technique in modified Gauss-Bonnet $f(\mathcal{G})$ theory of gravity (where $\mathcal{G}$ represents Gauss-Bonnet term). We assume isotropic matter configuration and spherically symmetric metric. We construct three $f(\mathcal{G})$ models, i.e, linear, quadratic and exponential forms and examine the consistency of these models. The traversable nature of wormhole solutions is discussed via null energy bound of the effective stress-energy tensor while physical behavior is studied through standard energy bounds of isotropic fluid. We also discuss the stability of these wormholes inside the wormhole throat and conclude the presence of traversable and physically stable wormholes for quadratic as well as exponential $f(\mathcal{G})$ models.

description: A new nonlinear electromagnetic wave mode in a magnetized dusty plasma is predicted. Its existence depends on the interaction of an intense circularly polarized electromagnetic wave with a dusty plasma, where quantum electrodynamical photon-photon scattering is taken into account. Specifically, we consider a dusty electron-positron-ion plasma, and show that the propagation of the new mode is admitted. It could be of significance for the physics of supernova remnants and in neutron star formation.

Our approach enables to compute also the pairwise correlation function of a randomly branched polymer in a 3D semi-space.

More generally, this kinetic duality principle produces regularity results where one can trade a loss of regularity or integrability somewhere in the kinetic transport equation for a suitable opposite gain elsewhere. Also, it looks simpler and more robust to rely on proving inequalities instead of constructing exact parametrices. The results in this article are introduced from a functional analytic point of view. They are motivated by the abstract regularity theory of kinetic transport equations. However, we may recall that velocity averaging lemmas have profound implications in kinetic theory and its related physical models. In particular, the precise formulation of such results has the potential to lead to important applications to the regularity of renormalizations of Boltzmann-type equations, as well as kinetic formulations of gas dynamics, for instance.

description: Az éghajlatváltozás globális hatásainak Európa is kiszolgáltatott. Így megnövekedett annak az igénye, hogy az Európai Unió adaptációs és mitigációs intézkedéseket építsen be szakpolitikáiba. Hosszabb távra azonban összehangolt és megfelelő pénzügyi háttérrel rendelkező EU-s klímastratégia szükséges. A megváltozó éghajlat kulcstényező az európai mezőgazdaság és vidék fejlődésében, ezért a közeljövő Közös Agrárpolitikáját (KAP) már ehhez javasolt igazítani. A fenntartható termelést elősegítik a 2007–2013-as EU-s vidékfejlesztési intézkedések, melyek nagy része a mitigációt is ösztönzi. Ezért az EU további vidékfejlesztési többletforrásokat csoportosított az éghajlatváltozás okozta hatások mérséklésére és az adaptáció növelésére. Véleményem szerint az EU azonnali cselekvése pozitívan értékelhető, azonban ezen intézkedések hasznosulása nehezen lesz kimutatható az EU–27 szintjén, mert az eredmények mérhetőségére nincsen egységes rendszer. Jelen tanulmány legfőbb célja, hogy rámutasson, a KAP fokozott jelentőségére a klímaváltozás tekintetében. -------------------------------------------------- Europe will also feel the impact of the global effects of climate change. This makes it highly necessary that the European Union include adaptation and mitigation measures in its policies. On a longer term, however, a coordinated and financially backed EU climate strategy is needed. The changing climate is a key factor in the development of Europe¬an agriculture and rural areas, and therefore the Common Agricultural Policy (CAP) of the near future should be formulated accordingly. The Community’s rural development measures for 2007-2013 promote sustainable production, and many of them encourage mitigation. Therefore the EU has re-allocated additional rural development resources to mitigate the impact of climate change and to promote adaptation. I think that this immediate action taken by the EU is a positive move. The usefulness of these measures will, however, be difficult to assess at the EU-27 level because no single system exists to measure the results. The main goal of this paper is to highlight the importance of CAP with respect to climate change.

description: Az általunk kidolgozott Biomassza Termelési Modell (BTM) lineáris programozáson alapul, és lehetővé teszi, hogy adott mezőgazdasági területre vonatkozóan meghatározzák az optimális vetésszerkezetet, különböző célfüggvények mellett. A különböző célfüggvények esetére vonatkozó optimalizálást a gazdasági környezet, különösen a szabályozó rendszer változása miatt tartottuk szükségesnek, amely adott körülmények között a legkedvezőbb gazdasági haszonnal jár. A döntés fő kérdése, hogy a rendelkezésre álló földterület és erőforrás-kapacitás mellett élelmiszercélú, vagy inkább energetikai célú hasznosítás irányában célszerű-e elmozdulni. --------------------------------------- We have developed a Biomass Production Model (BTM), which is based on linear programming. It enables us to identify the optimal crop structure for a specific piece of agri-cultural land, based on various target functions. Optimisation for different target functions was made necessary by the changing economic environment, especially the changes in the regulatory framework, to identify the most profitable option under the specific circumstances. The key question to be decided for any land and resource available is whether it is advised to opt for food crops or energy crops.

description: We examine the effect of the market share of supercenter stores on consumers’ food-at-home purchasing habits in the United States. We measure healthfulness several different ways to ensure robustness, but all measurements place a greater value on fresh fruits and vegetables and whole grains than on processed foods high in sugar and sodium. The results show that consumers, on average, purchase less healthful foods at supercenters than they do at supermarkets. Moreover a one-percent increase in the local market share of supercenters results in a decrease in purchase healthfulness for groceries of 0.5 to two percent.

Magnetic vortex dynamics in a 2D easy plane ferromagnet
Creators: name: Thompson, Lara
Publisher: name: University of British Columbia
Year: 2009

description: In this thesis, we consider the dynamics of vortices in the easy plane insulating ferromagnet in two dimensions. In addition to the quasiparticle excitations, here spin waves or magnons, this magnetic system admits a family of vortex solutions carrying two topological invariants, the winding number or vorticity, and the polarization. A vortex is approximately described as a particle moving about the system, endowed with an effective mass and acted upon by a variety of forces. Classically, the vortex has an inter-vortex potential energy giving a Coulomb-like force (attractive or repulsive depending on the relative vortex vorticity), and a gyrotropic force, behaving as a self-induced Lorentz force, whose direction depends on both topological indices. Expanding semiclassically about a many-vortex solution, the vortices are quantized by considering the scattered magnon states, giving a zero point energy correction and a many-vortex mass tensor. The vortices cannot be described as independent particles—that is, there are off-diagonal mass terms, such as [Equation], that are non-negligible. This thesis examines the full vortex dynamics in further detail by evaluating the Feynman-Vernon influence functional, which describes the evolution of the vortex density matrix after the magnon modes have been traced out. In addition to the set of forces already known, we find new damping forces acting both longitudinally and transversely to the vortex motion. The vortex motion within a collective cannot be entirely separated: there are damping forces acting on one vortex due to the motion of another. The effective damping forces have memory effects: they depend not only on the current motion of the vortex collection but also on the motion history.

description: Researchers have been using the latent class model (LCM) to value recreational activities for years. Then the reliability of this model becomes an issue. We conduct Monte Carlo simulations to test if the latent class model is able to recover the truth. The simulation results show that LCM does a better job on recovering population average values than recovering underlying population segments.

description: While farmland rental markets are likely to be spatially differentiated, the fine spatial structure of row-crop quality land should have a significant effect on cash rent determination. This study provides a rigorous empirical understanding of the effect of land spatial heterogeneity on cash rental rates. The lacunarity index is employed to measure spatial heterogeneity of land quality, which is built directly upon a soil quality measure, the land parcel’s corn suitability rating index (CSR). A panel data random effect model is applied on annual survey data of farmland cash rental rates of Iowa for 1987-2009. As expected, land spatial heterogeneity has a statistically significant and negative effect on local cash rent rates. The effect’s origin warrants further research.

description: In the present work, we investigated the electronic and elastic properties in equilibrium and under strain of the type-II Dirac semimetal NiTe$_2$ using density functional theory (DFT). Our results demonstrate the tunability of Dirac nodes' energy and momentum with strain and that it is possible to bring them closer to the Fermi level, while other metallic bands are supressed. We also derive a minimal 4-band effective model for the Dirac cones which accounts for the aforementioned strain effects by means of lattice regularization, providing an inexpensive way for further theoretical investigations and easy comparison with experiments. On an equal footing, we propose the static control of the electronic structure by intercalating alkali species into the van der Waals gap, resulting in the same effects obtained by strain-engineering and removing the requirement of in situ strain. Finally, evaluating the wavefunction's symmetry evolution as the lattice is deformed, we discuss possible consequences, such as Liftshitz transitions and the coexistence of type-I and type-II Dirac cones, thus motivating future investigations.
