description: Ein derzeit weit diskutiertes Thema ist die vierte Reinigungsstufe auf Kläranlagen. Diese erlangt durch die stetig steigenden Anforderungen an das gereinigte Abwasser immer mehr an Bedeutung. Jedoch sind Verfahren der Aktivkohle-Adsorption, Membranfiltration oder Ozonung für Kläranlagen mit der Größenklasse 4 und kleiner nur bedingt wirtschaftlich umsetzbar. Ziel dieser Arbeit ist es daher, herauszufinden, inwieweit ein Trommelfilter mit einer Bespannung von 77 μm Maschenweite diese Aufgabe übernehmen kann. Dazu wurde ein Teilvolumenstrom von ca. 50 m³/h vom Ablauf der Zentralkläranlage in Braunsbedra mit der Größenklasse 4 filtriert. Der erhaltene Filterkuchen wurde dabei unter anderem spektroskopisch und thermogravimetrisch untersucht. Für die infrarotspektroskopischen und die raman-spektroskopischen Untersuchungen wurde der Filterkuchen mit Wasserstoffperoxid und Schwefelsäure oxidiert, um störende Begleitorganik zu entfernen. Im Zentrum der Arbeit stand die Identifizierung und Quantifizierung der Kunststoffpartikel. Während der Versuchsdauer von 45 Tagen wurden 43.000 m³ Abwasser filtriert. Die Partikelkonzentration von 96 Partikel/m³ wurde durch Auszählen mittels Mikroskops bestimmt. Bei den Partikeln > 500 μm waren 83 % aus Polyethylen, 14 % aus Polypropylen und 3 % aus Polyamid. Es ist demnach davon auszugehen, dass Kunststoffe mit einer Dichte > 1 kg/dm³ in den vorhergehenden Reinigungsschritten entfernt wurden und sich somit vermutlich aufkonzentriert im Klärschlamm finden lassen. Eine Identifikation der Partikel < 500 μm ist aufgrund der Fett enthaltenden Matrix nicht gelungen. Relevant ist es nun herauszufinden, welche Mengen an Mikroplastik nicht zurückgehalten wurden, ebenso ist zu ermitteln, welche Auswirkungen das Mikroplastik in der Aquatik hat und wie die Emission weiter verringert werden kann.

description: Advances in high angular resolution astronomy make it conceivable that black hole dark matter could be detected via angular deviation effects. Assuming the dark matter in the galaxy is made of solar mass black holes, there is a non-trivial probability that a line-of-sight through the galaxy, leads to micro-arcseconds deviations, a value that has been discussed for various astronomical projects. In cosmology the effects are magnified by an increased density at early times and an opening of angles due to redshift. If the dark matter is made of primordial black holes, present at the CMB, random deflections of the CMB photons lead to a limit on the angular resolution, approximately ${3}\times 10^{-7} \sqrt{M/M_\odot}\, rad$, with $M$ the mass of the black holes. Using the resolutions of $\sim 10^{-3} rad$ demonstrated in observations of the "acoustic peaks" then implies the limit $(M/M_\odot)\lesssim 10^{7}$. While this large value seems uninteresting, improved resolutions would lead to significant limits or conceivably the discovery of primordial black holes.

description: In an effort to better calibrate the supernova rate of starburst galaxies as determined from near-IR [Fe II] features, we report on a [Fe II] 1.644 microns line-imaging survey of a sample of 42 optically-selected SNRs in M33. A wide range of [Fe II] luminosities are observed within our sample (from less than 6 to 695 L_sun). Our data suggest that the bright [Fe II] SNRs are entering the radiative phase and that the density of the local ISM largely controls the amount of [Fe II] emission. We derive the following relation between the [Fe II] 1.644 microns line luminosity of radiative SNRs and the electronic density of the postshock gas, n_e: L_[Fe II] (L_sun) ~ 1.1 n_e (cm^-3). We also find a correlation in our data between L_[Fe II] and the metallicity of the shock-heated gas, but the physical interpretation of this result remains inconclusive, as our data also show a correlation between the metallicity and n_e. The dramatically higher level of [Fe II] emission from SNRs in the central regions of starburst galaxies is most likely due to their dense environments, although metallicity effects might also be important. The typical [Fe II]-emitting lifetime of a SNR in the central regions of starburst galaxies is found to be of the order of 10^4 yr. On the basis of these results, we provide a new empirical relation allowing the determination of the current supernova rate of starburst galaxies from their integrated near-IR [Fe II] luminosity.

description: Organic farming provides social, economic and environmental benefits but it still occupies a small share of the overall agriculture sector. The objective of this study is to assess factors identifying the underlying issues leading farmers to adopt organic farming. The study was conducted in Chitwan district where indiscriminate use of agro-chemicals is very much existent but the concept of organic farming is also emerging especially in three village development committees within the district; namely Phoolbari, Shivanagar and Mangalpur. Based on field observation, the farming system is categorized into organic, partial organic and inorganic farming. Data from 285 purposively selected households were analyzed using Multinomial Logit model in Stata 13. Results show that older farmers are reluctant to change and thus has lower tendency to adopt organic farming. On the other hand, livestock holding is very crucial as it supplies the much needed manure for fertilizing the soil. More significantly membership in a group formed for the purpose of organic farming and the extent of activities such as training conducted through it has been very much successful in encouraging farmers to convert to organic or at least partial organic farming. Thus, formation of such groups in other areas could be the most effective tool for large scale conversion to organic farming.

description: We discuss the origin of the associativity (WDVV) equations in the context of quasiclassical or Whitham hierarchies. The associativity equations are shown to be encoded in the dispersionless limit of the Hirota equations for KP and Toda hierarchies. We show, therefore, that any tau-function of dispersionless KP or Toda hierarchy provides a solution to associativity equations. In general, they depend on infinitely many variables. We also discuss the particular solution to the dispersionless Toda hierarchy that describes conformal mappings and construct a family of new solutions to the WDVV equations depending on finite number of variables.

description: Road accident statistics are collected from information about personal injury road accidents and their consequent casualties, to a common national standard. The aim of collecting and publishing national road accident statistics is to inform public debate and to provide the basis for determining and monitoring effective road safety policies to reduce the road accident casualty toll. They are an essential requirement for monitoring targeted reductions in road accident casualties. The credible monitoring of targeted reductions requires that data are reported consistently and accurately, and both national and local government, and local reporting police forces, work closely to achieve a common reporting standard.

Users should note that for 1985-1991, and from 2002 onwards, the Vehicle Record file does not contain breath test data. This change has been made in order to protect confidentiality.

Data for 1985-1990 were deposited at the Archive at the beginning of 2006. Prior to this, the Archive only held the Road Accident Data series from 1991 onwards. No extra documentation was available for the 1985-1990 data, so users are advised to consult the documentation for the 1991 survey.

Further information about the Road Accident Data series and research based on it may be found on the government road accidents and safety statistics webpages.

These studies comprise information gathered using STATS19 and STATS20 forms.
Impedance of a Rectangular Beam Tube with Small Corrugations

Year: 2002
Subjects: subject: Accelerator Physics (physics.acc-ph)

description: We consider the impedance of a structure with rectangular, periodic corrugations on two opposing sides of a rectangular beam tube. Using the method of field matching, we find the modes in such a structure. We then limit ourselves to the the case of small corrugations, but where the depth of corrugation is not small compared to the period. For such a structure we generate analytical approximate solutions for the wave number $k$, group velocity $v_g$, and loss factor $κ$ for the lowest (the dominant) mode which, when compared with the results of the complete numerical solution, agreed well. We find: if $w\sim a$, where $w$ is the beam pipe width and $a$ is the beam pipe half-height, then one mode dominates the impedance, with $k\sim1/\sqrt{wδ}$ ($δ$ is the depth of corrugation), $(1-v_g/c)\simδ$, and $κ\sim1/(aw)$, which (when replacing $w$ by $a$) is the same scaling as was found for small corrugations in a {\it round} beam pipe. Our results disagree in an important way with a recent paper of Mostacci {\it et al.} [A. Mostacci {\it et al.}, Phys. Rev. ST-AB, {\bf 5}, 044401 (2002)], where, for the rectangular structure, the authors obtained a synchronous mode with the same frequency $k$, but with $κ\simδ$. Finally, we find that if $w$ is large compared to $a$ then many nearby modes contribute to the impedance, resulting in a wakefield that Landau damps.

description: Azerbaijan is a net-importer of wheat with average self-sufficiency ratio of 55%. In order to meet the domestic needs completely, Azerbaijan imports wheat mainly from Kazakhstan and Russia. The objective of this study is to investigate the extent of market power exercised by the Kazakh and Russian exporters in Azerbaijani wheat import market. Toward this aim, we apply the Residual Demand Elasticity approach, and fit the model with monthly time-series data covering the period from January 2004 to December 2013. Total export quantity of an exporting country and population of an importing country are selected as excluded variables in this analysis. The empirical results demonstrate that the Russian exporters exercise market power in Azerbaijani wheat market, but the Kazakh exporters face perfect competition. Moreover, we argue that the Ukrainian exporters are able to constraint both Kazakh and Russian exporters’ market powers in Azerbaijani wheat market.

description: Extensive simulations are performed to study the persistence behavior of a conserved lattice gas model exhibiting an absorbing phase transition from an active phase into an inactive phase. Both the global and the local persistence exponents are determined in two and higher dimensions. The local persistence exponent obeys a scaling relation involving the order parameter exponent of the absorbing phase transition. Furthermore we observe that the global persistence exponent exceeds its local counterpart in all dimensions in contrast to the known persistence behavior in reversible phase transitions.

description: We analyze the structure of supersymmetric Godel-like cosmological solutions of string theory. Just as the original four-dimensional Godel universe, these solutions represent rotating, topologically trivial cosmologies with a homogeneous metric and closed timelike curves. First we focus on "phenomenological" aspects of holography, and identify the preferred holographic screens associated with inertial comoving observers in Godel universes. We find that holography can serve as a chronology protection agency: The closed timelike curves are either hidden behind the holographic screen, or broken by it into causal pieces. In fact, holography in Godel universes has many features in common with de Sitter space, suggesting that Godel universes could represent a supersymmetric laboratory for addressing the conceptual puzzles of de Sitter holography. Then we initiate the investigation of "microscopic" aspects of holography of Godel universes in string theory. We show that Godel universes are T-dual to pp-waves, and use this fact to generate new Godel-like solutions of string and M-theory by T-dualizing known supersymmetric pp-wave solutions.

description: In most developing countries data limitations lead to the use of assumptions that compromise studies on the measurement of capital and its impact on productivity analysis. A possible approach is to use the ratio of the value of tractor sales to overall expenditure to impute overall machinery sales. The use of a constant ratio over an extended period results in increasingly incorrect estimates and fails to reveal the changing nature of mechanisation. In this paper, the probems with such an approach are highlighted through an analysis of the historic share of tractor sales to overall machinery sales in South Africa. This paper establishes that the current methods lead to underestimation in the overall value of machinery and implements sales in South Africa by approximately a $100 million per annum in recent years. An alternative method is suggested and the implications of a new capital formation series are discussed.

description: Menschen gelten als soziale Wesen, welche mittels persönlicher Beziehungen zu anderen Personen sowohl ihre Sozialität sowie ihre soziale Integration empfangen und beibehalten (vgl. Lenz und Nestmann 2009b: S. 9). Dabei wird in den vielfachen Ausprägungen persönlicher Beziehungen die Paarbeziehung als äußerst intensive Form beschrieben (vgl. Ebbecke-Nohlen 2009: S. 859). Aufgrund dieses Wandels in den Beziehungsmodellen westlicher Kulturen, widmet sich diese Ausarbeitung der Forschungsfrage, inwiefern Personen, welche in polyamoren Beziehungen leben, sich mit ihren persönlichen und den Bedürfnissen ihrer Beziehungspersonen auseinandersetzen, im Vergleich zu monogamen Menschen. Um dieses Vorhaben entsprechend eingrenzen zu können, fokussiert diese kontrastierende Arbeit die Dimensionen kommunikativer Aushandlungsprozesse, dem Treueverständnis sowie der Vorstellung von romantischer Liebe und Sexualität. Auch wird ein entsprechender Bezug zu der Sozialen Arbeit durch eine Betrachtung der Beratung monogamer und nicht-monogamer Personen hergestellt. Diese Einsicht bildet ab, dass ein sex-positiver Blick in der Beratung Klient*innen, unabhängig derer Beziehungsmodelle, darin unterstützt, sich über ihre persönliche sexuelle Orientierung hinaus, dem eigenen Wohlbefinden und dem Erleben von selbstbestimmten, angenehmen sexuellen Erfahrungen in selbstgewählten Beziehungen widmen zu können. Auch zeigt sich, dass sowohl die Monogamie als auch die Polyamorie durch die untersuchten Dimensionen geprägt werden und Personen individuell miteinander verbinden.

Dieses Werkzeug soll es ermöglichen die Zuverlässigkeit sowie Claimbasierte Berechtigungskonzepte von RESTful Webservices anhand ihrer OpenAPI-Dokumentation zu überprüfen. Dabei wird untersucht, ob sich das Verhalten des zu testenden Systems mittels zustandsabhängiger Eigenschaften spezifizieren lässt und welchen Einfluss diese auf das Finden von Fehlern haben. Um diese Frage zu beantworten, wurde mit dem entwickelten Test-Tool, REST-QA, ein Teil der GitLab- Schnittstelle validiert. Die Auswertung hat gezeigt, dass die vorgeschlagenen zustandsabhängigen Eigenschaften im generischen Kontext nicht allgemeingültig sind. Mit diesen Eigenschaften konnten in GitLab keinerlei Fehler gefunden werden. Jedoch kann damit keine Aussage über den tatsächlichen Nutzen dieser getroffen werden, da die Validierung nur an einem einzelnen RESTful Webservice durchgeführt wurde. Dessen ungeachtet konnte REST-QA zwei neue Fehler in der GitLab-Schnittstelle entdecken. Die Arbeit stellt somit ein weiteres Beispiel für die Machbarkeit und den Nutzen des zu Grunde liegenden Ansatzes für das Testen von RESTful Webservices mittels der Open- API-Dokumentation dar.

description: The objective is to provide an estimate of the use value of the U.S. High Plains aquifer in agriculture. A regional production function for the crop sector, based on countylevel observations, was estimated. Two main estimation procedures were used. The first used a system of equations and instrumental variables, the second accounted for spatial effects. Using the estimated production responses to irrigation, we estimate the average gross value of groundwater for agriculture to be $165/acre at 2007 prices. Using spatial statistical analysis, we found significant spatial relationships that increased this estimate to $174

description: Some short gamma-ray bursts (SGRBs) are thought to be caused by the mergers of binary neutron stars which may sometimes produce massive neutron star remnants capable of producing extragalactic fast radio bursts (FRBs). We conducted a deep search for FRBs from the sites of six low-redshift SGRBs. We collected high time- and frequency-resolution data from each of the sites for 10 hours using the 2 GHz receiver of the Green Bank Telescope. Two of the SGRB sites we targeted were visible with the Arecibo Radio Telescope with which we conducted an additional 10 hours of 1.4 GHz observations for each. We searched our data for FRBs using the GPU-optimized dedispersion algorithm $\texttt{heimdall}$ and the machine-learning-based package $\texttt{FETCH}$ (Fast Extragalactic Transient Candidate Hunter). We did not discover any FRBs, but would have detected any with peak flux densities in excess of 87 mJy at the Green Bank Telescope or 21 mJy at Arecibo with a signal-to-noise ratio of at least 10. The isotropic-equivalent energy of any FRBs emitted from these sites in our bands during our observations must not have exceeded a few times $10^{38}$ erg, comparable to some of the lowest energy bursts yet seen from the first known repeating FRB 121102.

description: The hypothesis that six EU Member States show a common behavior on the implementation of food safety standards on fruits and vegetables imports is examined. To do so, we analyzed food border notifications recorded by the Rapid Alert System for Food and Feed (RASFF). Path dependence and reputation effects of past border notifications were explored for the whole period 2001-13, and for sub-periods 2001-07 and 2008-13. Negative binomial (NB) and zero-inflated negative binomial (ZINB) distributions were used to deal with over-dispersion and excess of zero counts. Our findings suggest thatthe EU cannot be considered as a single unit when non-tariff measures are studied, although there are some signs that MS behavior is becoming more uniform in the latest period.

description: We study the effect of fluid flow on three-dimensional (3D) dendrite growth using a phase-field model on an adaptive finite element grid. In order to simulate 3D fluid flow, we use an averaging method for the flow problem coupled to the phase-field method and the Semi-Implicit Approximated Projection Method (SIAPM). We describe a parallel implementation for the algorithm, using Charm++ FEM framework, and demonstrate its efficiency. We introduce an improved method for extracting dendrite tip position and tip radius, facilitating accurate comparison to theory. We benchmark our results for two-dimensional (2D) dendrite growth with solvability theory and previous results, finding them to be in good agreement. The physics of dendritic growth with fluid flow in three dimensions is very different from that in two dimensions, and we discuss the origin of this behavior.

The proposed approach provides an explanation for fundamental interactions, dark matter and dark energy anomalies, Heisenberg's uncertainty principle, and offers an alternative to the concepts of space curvature and the Higgs field. Calculations demonstrate that rest mass can be expressed in terms of wavelength at the speed of light, as well as through an energy ratio, reducing the expression to wavelength, Planck’s constant, and the speed of light. The interpretation of gravity, electromagnetic, strong, and weak interactions through energy density is discussed. This approach offers a new perspective on the nature of mass and its connection to fundamental forces, potentially leading to new experimental verifications and a more comprehensive description of physical reality.

 

В данной работе рассматривается гипотеза о том, что масса элементарных частиц является следствием изменения плотности энергии в пространстве. Предлагаемый подход позволяет объяснить фундаментальные взаимодействия, аномалии тёмной материи и тёмной энергии, неопределённость Гейзенберга, а также предложить альтернативу концепции искривления пространства и полю Хиггса. Представлены расчёты, показывающие, что масса покоя может быть выражена через длину волны при движении со скоростью света, а также через отношение энергий, где остаются только длина волны, постоянная Планка и скорость света. Обсуждается возможность интерпретации гравитации, электромагнитного, сильного и слабого взаимодействий через плотность энергии. Такой подход позволяет по-новому взглянуть на природу массы и её связь с фундаментальными силами, что может привести к новым экспериментальным проверкам и более целостному описанию физической реальности.

description: The purpose of this study is to measure the sensitivity of trade to agricul- tural productivity shocks, using country-level data on yield and production combined with bilateral trade data for a wide range of countries and products for the years 2000-2010. We find that traded quantities react in the expected direction but that the magnitudes are smaller than predicted by theory. The results suggest that trade frictions, product differentiation and storage limit the role of international trade as way of coping with production volatility. We find that import unit values increase in years when domestic production is relatively high. We consider alternative explanations for this such as quality sorting or economies of scale in international shipping. Import price declines in years when importers have a poor domestic production may act as a coping mechanism for countries that suffer from adverse food production conditions.

description: This paper is one in a series that explores the importance of radius as a second parameter in galaxy evolution. The topic investigated here is the relationship between star formation rate (SFR) and galaxy radius ($R_{\rm e}$) for main-sequence star-forming galaxies. The key observational result is that, over a wide range of stellar mass and redshift in both CANDELS and SDSS, there is little trend between SFR and $R_{\rm e}$ at fixed stellar mass. The Kennicutt-Schmidt law, or any similar density-related star formation law, then implies that smaller galaxies must have lower gas fractions than larger galaxies (at fixed $M_{\ast}$), and this is supported by observations of local star-forming galaxies. We investigate the implication by adopting the equilibrium "bathtub" model: the ISM gas mass is assumed to be constant over time and the net star formation rate is the difference between the accretion rate of gas onto the galaxy from the halo and the outflow rate due to winds. To match the observed null correlation between SFR and radius, the bathtub model requires that smaller galaxies at fixed mass have weaker galactic winds. Our hypothesis is that galaxies are a 2-dimensional family whose properties are set mainly by halo mass and concentration. Galaxy radius and accretion rate plausibly both depend on halo concentration, which predicts how wind strength should vary with $R_{\rm e}$ and SFR.

description: In this paper the stochastic metafrontier method is applied to estimate technical efficiency (TE) and metatechnology ratios (MTR), in beef cattle production for three distinct regions in Argentina. A deterministic stochastic metafrontier production function model is estimated that envelops the individual stochastic frontiers of the three regions. Our results show that firms from Pampean region, the most favored in terms of environment conditions, have an average (TE) of 53.7%, meanwhile for others regions the TE is around 58.9-66.97%. The average MTR for Pampean region is 96.8%, in contrast, the others regions have an average MTR of 42%. Our results suggest that, farms in the Pampean region could improve their performance through a better management using the available technologies and resources. In regions II and III the improvement of the productivity is likely to require additional investment in research to adapt and develop new technologies.

description: We report high sensitivity dual-frequency observations of radio oscillations from GRS 1915+105 following the decay of a major flare event in 2000 July. The oscillations are clearly observed at both frequencies, and the time-resolved spectral index traces the events between optically thin and thick states. While previously anticipated from sparse observations and simple theory, this is the first time a quasi-periodic signal has been seen in the radio spectrum, and is a clear demonstration that flat radio spectra can arise from the combination of emission from optically thick and thin regions. In addition, we measure the linear polarisation of the oscillations, at both frequencies, at a level of about 1--2%, with a flat spectrum. Cross-correlating the two light curves we find a mean delay, in the sense that the emission at 8640 MHz leads that at 4800 MHz, of around 600 seconds. Comparison with frequency-dependent time delays reported in the literature reveals that this delay is variable between epochs. We briefly discuss possible origins for a varying time delay, and suggest possible consequences.

A local-global principle for surjective polynomial maps

description: Let $R$ be an affine domain of characteristic zero with finite quotients. We prove that a polynomial map over $R$ is surjective if and only if it is surjective over $\hat{R_{\mathfrak{m}}}$, the completion of $R$ with respect to $\mathfrak{m}$, for every maximal ideal $\mathfrak{m} \subseteq R$. In fact, the completions $\hat{R_{\mathfrak{m}}}$ may be replaced by arbitrary subrings containing $R$. We use this result to yield a characterization of surjective polynomial maps, and remark that there does not exist a similar principle for injective polynomial maps.
