description: Für einen profitablen Anbau von Pflanzen in geschlossenen Kultursystemen ist der Einsatz elektrischer Energie zu optimieren. Wesentlich hierfür ist das Erlangen von Kenntnissen über den Zusammenhang zwischen Bestrahlungssituation und Pflanzenwachstum. Als potentielles Maß für die Wachstumsleistung gilt die Photosyntheserate der Pflanze, die durch die Messung der CO2-Aufnahme eines Blattes ermittelt wird. Von Vorteil ist hierbei, dass Auswirkungen auf die Photosynthese im Gegensatz zum Wachstum direkt messbar sind. Aus diesem Grund wird zunächst der Einfluss von verschiedenen Bestrahlungsspektren auf die Photosyntheserate untersucht. Das Ergebnis zeigt, dass die spektrale Zusammensetzung des Lichts messbare Auswirkungen auf die Photosyntheserate hat. Um zukünftig den Zusammenhang zwischen Photosyntheserate und Pflanzenwachstum zu untersuchen zeigt der Ausblick, wie hierfür Versuchsstände in weiteren Studien aufgebaut sein können. Mit diesen können verschiedene Wachstumsparameter erfasst, und damit wiederum Korrelationen festgestellt werden.

description: Fahrten im Straßenverkehr sind durch sich ständig verändernde Lichtsituationen charakterisiert, die sowohl zeitlich als auch örtlich eine hohe Dynamik aufweisen. Ist die Dynamik innerhalb des Gesichtsfeldes des Beobachters so hoch sodass es das Auge nicht schafft sich entsprechend anzupassen, wird dies als Blendung bezeichnet. Während dieses Anpassungsprozesses verfügt das visuelle System nicht über seine optimale visuelle Leistungsfähigkeit, sodass potentiell gefährliche Objekte unter Umständen zu spät oder gar nicht erkannt werden können. Um das damit verbundene Gefährdungspotential besonders in Blendsituationen mithilfe von Probandenstudien evaluieren zu können, wurde eine objektive Messmethode, die sogenannte MeLLIMethode (Measurement of glaring Light stimuli with Letter Identification) entwickelt und erfolgreich validiert.

description: Golf carts are increasingly being used as a means of transportation for travel in neighborhoods, city areas, and unpaved surfaces. The catchment area of our regional trauma center has seen an increase in golf cart use for transportation. In fact, Georgia has recently changed legislation to support the growing need for more defined laws around golf cart use. This study aims to further evaluate injury and outcome patterns in the adult population of northeast Georgia. We performed a retrospective review of adult golf cart injured patients from 2018 to 2022. We evaluated key demographics, such as age and gender, along with the length of stay, Glasgow Coma Scale (GCS), and Injury Severity Score (ISS). Outcomes included the injury type. The results showed that orthopedic injuries were the most common (n = 24). Most patients were in the driver’s seat (76%). Ejection from the golf cart was common (82%). Geriatric patients, 65 and older, had an increased length of stay compared to patients under the age of 65 (10 vs 3.9 days). Based on these results, future work includes injury prevention, increased awareness of injury patterns in prehospital and hospital settings, and communities updating their ordinances.

description: Dilute acid pretreatment of lignocellulosic biomass depolymerizes xylan into xylose and lignin into acid-soluble lignin (ASL). Xylose is a desired product, while the lignin fraction can be reduced by producing ASL, since lignin is a non-competitive inhibitor for enzymatic hydrolysis. The optimal conditions for depolymerization of xylan into xylose and lignin into ASL differ during acid pretreatment of bagasse. Hence, multi-objective optimization problems (MOOPs) were formulated for a batch reactor considering temperature as the decision variable. Two different MOOP studies, namely maximization of the weighted sum of final xylose and ASL yields, and minimization of weighted deviation of final xylose and ASL yields around a targeted value, were considered. The optimal temperature varied between 143.2 °C and 113.1 °C along the Pareto front for static optimization. The batch time minimization problem reduced batch time by 32% to achieve desired xylose yield. Dynamic optimization provided minimal benefits over static optimization. Stochastic optimization considering expected uncertainties showed that uncertainties in kinetic parameters impacted results selectively. The optimal temperature decreased by 10 °C for ± 15% variability in kinetic parameters for ASL yield maximization, while it changed marginally for xylose yield maximization. Stochastic optimization showed benefits over static optimization for large variability in kinetic parameters.

description: We present a new pseudospectral approach for incorporating many-body, nonlocal exact exchange interactions to understand the formation of electron gases in core-shell nanowires. Our approach is efficiently implemented in the open-source software package PAMELA (Pseudospectral Analysis Method with Exchange & Local Approximations) that can calculate electronic energies, densities, wavefunctions, and band-bending diagrams within a self-consistent Schrodinger-Poisson formalism. The implementation of both local and nonlocal electronic effects using pseudospectral methods is key to PAMELA's efficiency, resulting in significantly reduced computational effort compared to finite-element methods. In contrast to the new nonlocal exchange formalism implemented in this work, we find that the simple, conventional Schrodinger-Poisson approaches commonly used in the literature (1) considerably overestimate the number of occupied electron levels, (2) overdelocalize electrons in nanowires, and (3) significantly underestimate the relative energy separation between electronic subbands. In addition, we perform several calculations in the high-doping regime that show a critical tunneling depth exists in these nanosystems where tunneling from the core-shell interface to the nanowire edge becomes the dominant mechanism of electron gas formation. Finally, in order to present a general-purpose set of tools that both experimentalists and theorists can easily use to predict electron gas formation in core-shell nanowires, we document and provide our efficient and user-friendly PAMELA source code that is freely available at http://alum.mit.edu/www/usagi

description: PHENIX reports on electromagnetic and hadronic observables in large data sets of p+p, d+Au and Au+Au collisions at various cms energies. Initial state effects in cold nuclear matter are quantified by centrality dependent $π^0$, $η$, reconstructed jets and $ψ\prime$ measurements. Using the first run of the new EBIS ion source at RHIC, we report first results for particle flow ($v_1$ and $v_2$) and quarkonium production in U+U and Cu+Au collisions. Hot matter created in Au+Au is characterized using event-plane dependent HBT and dielectrons. Parton-medium interactions are investigated using high $p_T$ single hadrons, $γ$-hadron correlations and heavy flavor decay electrons identified with the newly installed VTX detector.

description: The SW Sex stars are a class of cataclysmic variables, originally identified because they shared a number of enigmatic properties - most notably, single-peaked emission lines instead of the double-peaked lines one would expect from their high-inclination accretion discs. We present high time-resolution spectrophotometry of the eclipsing nova-like variables SW Sex and DW UMa, two of the founding members of the SW Sex class. Both systems show single-peaked Balmer and HeII 4686A emission lines that appear to originate from a region in the disc that lies close to, but downstream of, the bright spot. The emission-line light curves are consistent with the finding from X-ray and ultraviolet observations that we predominantly see the flared disc rim and the unobscured back portion of the disc in these systems. In DW UMa, the HeII 4686A emission line originates from close to the white dwarf and exhibits flaring. Such flares have been used to argue for magnetically-channelled accretion, as in the intermediate polars, but the lack of a clear periodicity in the flares argues for a simpler model in which we are viewing the central regions of the disc through the non-uniform upper edge of a flared disc rim. We also observe narrow, blue-shifted, transient absorption features in the Balmer lines of DW UMa, which we attribute to blobs of material ejected from the system, possibly by a magnetic propeller, that happen to be passing between us and the binary. Our results suggest that the solution to the SW Sex enigma is a combination of dominant bright-spot emission and a self-occulting disc. We also propose a simplified classification scheme for nova-like variables.

It is found that the Barr-Zee type fermion dipole moment with sfermion loop acts destructively to the currently known fermion loop contribution, and that it has small effect when the mass of squarks or charged sleptons in the loop is larger than or comparable to that of the sneutrinos, but cannot be neglected if the sneutrinos are much heavier than loop sfermions.

description: The beauty of the nature and the dynamics of the movements make the skiing one of the most popular and attractive sports in a lot of countries. The daylight skiing is the most often practice but not only. The night time practicing has its own beauty and is also attractive. For this purpose is needed appropriate artificial lighting. In some cases and for big international events it is obligatory. The visual tasks, the curved slope fields, the not smooth calculating surfaces, the snow reflection characteristics, the speed of the movement and recognition make this field of lighting design quite interesting and challenging as the sport itself. In the present paper it is proposed a practical solution for artificial lighting of a skiing slope, completed with 3D modelling of the track surface with its reflecting characteristics and fulfilling the standard requirements for artificial lighting of that kind of sport practicing.

description: Scheinwerfer mit adaptiver Lichtverteilung und Matrixbeam sind mittlerweile als Serienstand anzusehen. Die Anwendung verschiedener Projektionstechniken hingegen ist in der automobilen Lichttechnik noch in der Entwicklung. Da im Exterieurbereich die Nutzung von Projektionstechniken viele Vorteile, wie beispielsweise lichtbasierte Fahrerassistenz oder Kommunikation hinsichtlich autonomen Fahrens mit sich bringt, liegt die Überlegung nahe, diese auch im Interieurbereich zu nutzen. Mit Monitoren können verschiedene Nutzeranwendungen an festen, ebenen Flächen im Fahrzeuginneren dargestellt werden. Inhalte wie Messenger-Dienste, Social Media Anwendungen, News-Feeds oder Streaming Dienste sind hier möglich. Mit Hinblick auf autonom fahrende Fahrzeuge werden Techniken benötigt, die es erlauben relevante Informationen ortsunabhängig darzustellen. Dies ist bei der Verwendung von Monitoren durch die feste Einbauposition im Fahrzeug sowie die Flexibilität der Darstellung jedoch stark eingeschränkt. Der Einsatz von Projektionstechniken hingegen ermöglicht es, Informationen an beliebigen Positionen nutzerorientiert darzustellen und ist dabei nicht ausschließlich auf planare Oberflächen beschränkt. Theoretisch betrachtet kann jede beliebige Oberfläche im Fahrzeuginnenraum für die Projektionsdarstellung verwendet werden.

Also, mixing this with the techniques in J Symb Log 56(3):795-810, 1991, we can prove that it is consistent with ZFC to assign, at the same time, several arbitrary regular values on the left hand side of Cichon's diagram.

description: Die vom Kraftfahrzeuginsassen subjektiv wahrgenommene indirekte Beleuchtung ist das Resultat aus physio- und psychologischen Einflüssen des menschlichen Betrachters. Bei der Beleuchtungsvariante wird diese unter anderem von der Art der angeleuchteten Fläche und der Lichtquelle mitbestimmt. Zur Reduzierung der Variantenvielfalt bei der Fahrzeug-Innenlicht-Entwicklung werden oftmals baureihenübergreifende Leuchtmodule verwendet. Die emittierenden, leitenden und verteilenden Lichtmodule sind somit als annährend konstant anzunehmen, währenddessen die angeleuchtete Fläche nahezu frei vom Kunden konfigurierbar ist und von der gewählten Interieur-Ausstattung abhängt. Das nachfolgende Paper beschreibt eine mögliche Modellbildung für eine lichttechnische Oberflächencharakterisierung typischer texturierter Materialien im Fahrzeuginnenraum. Dabei setzt sich das Modell für die Oberfläche aus der spektralen Remissionseigenschaft, dem Streuverhalten sowie der Topologie zusammen. Der Schwerpunkt dieser Untersuchung liegt auf der Erstellung der sog. Wellenlinie der Topologie von genarbtem bzw. texturiertem Leder. Zur objektiven Messdatengenerierung des Modells werden hierbei, angefangen bei der klassischen BRDF bis hin zu genormten Flächencharakteristika – wie dem Flächenrauheitswert –, bereits vorhandene und meist genormte Kenngrößen verwendet. Somit wird im Vergleich zu den bisherigen Möglichkeiten eine Übertragbarkeit des Modells mit geringen Einflussfaktoren bezüglich der Datenermittlung, der Datenverarbeitung und der Datenextrahierung erreicht.

description: The nature of the pairing state in iron-based superconductors is the subject of much debate. Here we argue that in one material, the stoichiometric iron pnictide KFe2As2, there is overwhelming evidence for a d-wave pairing state, characterized by symmetry-imposed vertical line nodes in the superconducting gap. This evidence is reviewed, with a focus on thermal conductivity and the strong impact of impurity scattering on the critical temperature Tc. We then compare KFe2As2 to Ba0.6K0.4Fe2As2, obtained by Ba substitution, where the pairing symmetry is s-wave and the Tc is ten times higher. The transition from d-wave to s-wave within the same crystal structure provides a rare opportunity to investigate the connection between band structure and pairing mechanism. We also compare KFe2As2 to the nodal iron-based superconductor LaFePO, for which the pairing symmetry is probably not d-wave, but more likely s-wave with accidental line nodes.

description: Eine Möglichkeit hochauflösende Scheinwerfer im Automobil umzusetzen, sind scannende Systeme. Scannen bedeutet, dass ein Strahl von einer Ablenkeinheit umgelenkt wird, sodass ein Winkelbereich beleuchtet wird. Durch Modulation der Lichtquelle werden aus dem Winkelbereich nur die Winkel ausgewählt, die zur Erzeugung der Ziellichtverteilung beitragen. Damit die Lichtverteilung als statisch wahrgenommen wird, muss sich der Strahl ausreichend schnell bewegen. Das vorliegende Konzept verfolgt eine Ablenkung in einer Dimension. Der Strahl bewegt sich entlang einer Linie. Eine facettierte Optik verteilt das Licht, sodass die Ziellichtverteilung entsteht. Durch die Ablenkung in nur einer Dimension fallen die Anforderungen an das mechanische System und die Modulation der Lichtquelle moderater aus als bei vergleichbaren 2D-Scannern. Hauptaufgabe ist das Design der facettierten Optik. Weiterhin muss eine geeignete Lichtquelle gefunden und ein Beleuchtungspfad entworfen werden.

description: The recently proposed hard-pion chiral perturbation theory predicts that the leading chiral logarithms factorize with respect to the energy dependence in the chiral limit. This claim has been successfully tested in the pion form factors up to two loops in chiral perturbation theory. In the present paper we explain this factorization property at two loops and even show that it is valid to all orders for a subclass of diagrams. We also demonstrate that factorization is violated starting at three loops.

description: In recent years, automotive headlight systems have been improved in a considerable extent for a safer drive. In this paper, an optical design is presented for scanning headlight systems with an alternative deflection unit and an RGB laser source to optimise the light distribution and create desired illumination patterns adapting to the driving situation. Recently developed scanning lighting systems incorporate mechanical deflection systems. Here, since the redistribution of the light is mostly depending on the fixed deflection pattern, several drawbacks are emerging. As an alternative method, acousto-optic deflection technology can deflect the light without any mechanical displacement. They offer highflexibility to redistribute the light in the desired intensity. Thus, the main role can be undertaken by acousto-optic deflectors as laser scanners and illumination units. However, although they have a mechanic-free deflection mechanism, their narrow deflection range causes difficulties in realising the desired illumination and scanning applications. An optics design to enlarge the deflection range for Acousto-Optic Deflectors (AODs) is required. In this project, an optical system is purposed for high resolution and contrast illumination in automotive lighting using acousto-optic deflectors.

description: Vibrational properties of iron-chalcogenide superconductor K$_{0.75}$Fe$_{1.75}$Se$_{2}$ with $T_{c}\sim$ 30 K have been measured by Raman and optical spectroscopies over temperature range of 3-300 K. Sample undergoes \textit{I4/m} $\to $ \textit{I4} structural phase transition accompanied by loss of inversion symmetry at $T_{1}$, below 250 K, observed as appearance of new fully-symmetric Raman mode at $\sim$ 165 cm$^{-1}$. Small vibration mode anomalies are also observed at $T_{2}\sim$ 160 K. From first-principles vibrational analysis of antiferromagnetic K$_{0.8}$Fe$_{1.6}$Se$_{2}$ utilizing pseudopotentials all observed Raman and infrared modes have been assigned and the displacement patterns of the new Raman mode identified as involving predominantly the Se atoms.

Bei Scheinwerfer-Projektionssystemen wird der Übergang durch eine streuende Struktur auf der Linsenfläche aufgeweicht. Bisher erfolgte die Auslegung manuell. Diese Arbeit befasst sich mit der Auslegung strukturierter Flächen unter Anwendung von genetischen Algorithmen. Die Anforderungen an die Hell- Dunkel-Grenze eines Scheinwerfers werden erläutert. Es werden Verfahren dargestellt, um CAD-Flächen mit einer streuenden Struktur zu überlagern. Damit die Auslegung strukturierter Linsenflächen durch Optimierungsalgorithmen ermöglicht werden konnte, musste die Zeit für eine lichttechnische Simulation der Fläche reduziert werden. Die verwendete Simulationsmethodik wird erklärt und erste Ergebnisse diskutiert.

description: We present theoretical results of a low-loss all-optical switch based on electromagnetically induced transparency and the classical Zeno effect in a microdisk resonator. We show that a control beam can modify the atomic absorption of the evanescent field which suppresses the cavity field buildup and alters the path of a weak signal beam. We predict more than 35 dB of switching contrast with less than 0.1 dB loss using just 2 micro-Watts of control-beam power for signal beams with less than single photon intensities inside the cavity.

description: Die Licht-emittierende Diode (LED) gewinnt sowohl in der Haushalts- als auch in der Kfz-Beleuchtung stetig an Bedeutung. Der Umstieg von konventionellen Glühlampen zu LED-Leuchtmitteln erfolgt bereits seit einigen Jahren durch die Verwendung von sogenannten Retrofit-LEDs im Haushalt. Auch in der Kfz-Frontbeleuchtung wäre solch ein Wechsel technisch möglich. In Deutschland und Europa fehlen derzeit jedoch die rechtlichen Rahmenbedingungen für die Zulassung von Retrofit-LEDs. Dabei könnten sich durch die Verwendung von Retrofit-LEDs sowohl Vor- als auch Nachteile bezüglich der Sicherheit im nächtlichen Straßenverkehr ergeben. So könnte der mögliche höhere Lichtstrom und die kältere Lichtfarbe der Retrofit-LEDs zu einer höheren Leuchtweite und somit einer größeren Sichtbarkeitsweite führen. Diese Eigenschaften könnten jedoch ebenfalls für ein erhöhtes Blendpotential sorgen. Mit der durchgeführten Untersuchung wird eine Aussage bezüglich der Sicherheitserhöhung im nächtlichen Straßenverkehr durch die Verwendung von aktuell verfügbaren Retrofit-LEDs getroffen. Hierfür werden sowohl photometrische Messungen im Labor als auch ein Feldtest durchgeführt und ausgewertet.

A nova frescura (ou seria qualiragem mesmo?) é destacar que o PR Jair Bolsonaro falou em boiolagem com um copo com Cola Guaraná Jesus nas mãos. Sim, eu sou do tempo em que assim era chamado esse refrigerante.Pois bem, ele é refrescante, atende a héteros, gays e todo o resto do abecedário inventivo dos que não tem o que fazer.Sendo assim, o presidente deveria em terras maranhenses fazer a piada com qualiragem e não boiolagem.
title: The Strong Black Woman ≠ Superwoman: Shattering Stereotypes of Strength in Black Literature
Creators: name: Thomas, Tricia Inez
Publisher: name: Old Dominion University Libraries
Year: 2023

description: That the Black woman must be strong in order to endure the oppression she has been forced to withstand is a double-edged sword that equally contributes to both her dehumanization and willpower to survive. This project interrogates the patterns and characteristics that contribute to the schema of the strong Black woman through the examination of cultural texts foregrounded in biblical scriptures against literature written by prominent Black women through Beyoncé. Specific tropes explored include the jezebel, the mammy, and the sapphire with a conclusion that these harmful and dehumanizing stereotypes have cultivated a fallacious assumption of supernatural strength and resiliency that society has expected Black women to aspire to.

As such, the ideologies presented within this project are examined through the analysis of literary portrayals of hypersexualization and subsequent justification, self-erasure and mulehood, and Black girl magic and double and triple consciousness. A well-rounded framework for uncaping, or demystifying, the Black superwoman is made possible by bringing biblical beliefs to the table with scholarly and literary works, enhanced by discussions of theatrical and musical portrayals of Black women. This project proves that Black women have been severely mistreated long before and well after the institution of slavery in not limiting the contexts in which the controlling images of Black women are portrayed to a specific genre or time period. The Strong Black woman schema incessantly demands perfection in all that we do through the shattering of glass ceilings in an attempt to dismantle the master’s house. So, too, must the stereotypes that celebrate mythical supernatural strength and concurrently shame the Black woman be shattered.

description: We report on a multi-site photometric campaign on the high-amplitude $δ$ Scuti star V2367 Cyg in order to determine the pulsation modes. We also used high-dispersion spectroscopy to estimate the stellar parameters and projected rotational velocity. Time series multicolour photometry was obtained during a 98-d interval from five different sites. These data were used together with model atmospheres and non-adiabatic pulsation models to identify the spherical harmonic degree of the three independent frequencies of highest amplitude as well as the first two harmonics of the dominant mode. This was accomplished by matching the observed relative light amplitudes and phases in different wavebands with those computed by the models. In general, our results support the assumed mode identifications in a previous analysis of Kepler data.

description: We study supernova neutrino flux variations in the IceCube detector, using 3D models based on a simplified neutrino transport scheme. The hemispherically integrated neutrino emission shows significantly smaller variations compared with our previous study of 2D models, largely because of the reduced SASI activity in this set of 3D models which we interpret as a pessimistic extreme. For the studied cases, intrinsic flux variations up to about 100 Hz frequencies could still be detected in a supernova closer than about 2 kpc.

title: Vortex flows around morphing foils: reshape yourself to effect a change
Creators: name: Martínez Carmena, Alfonso
Publisher: name: University of Glasgow
Year: 2023

description: The unsteady production of vorticity is a unifying principle in biological locomotion in air and water. Shape-tailoring their aerodynamic/hydrodynamic surfaces, natural flyers/swimmers switch with ease between regimes of attached and separated flow. Modern engineering tries to mimic this shape control ability in applications such as micro air vehicles and oscillating energy harvesting devices. Owing to the complexity of morphing, fundamental research merits further efforts, to provide a clearer view of the link between shape variation and unsteady flow response. In this dissertation, classical theories (potential flow) are combined with numerical methods (vortex methods) in the development of a physics-based low-order model to simulate complex unsteady flows around foils undergoing large camber variations, as a first step towards exploring the capability of camber morphing to alter vortex characteristics, like formation time and strength. Discrete-vortex methods have risen as one of the most suitable numerical tools to establish a relation between camber definition, flow characteristics and aerodynamic loads produced, involving a reasonably low number of parameters. An existing discrete-vortex model for rigid foils is extended to variable-camber foils. A time-varying chord line is proposed, where the boundary condition in thin-aerofoil theory is to be satisfied. This enables large deformations of the camber line to be modelled. Computational fluid dynamics simulations at Reynolds numbers of O(104) are used to test the performance of the model. Furthermore, a new method is introduced to determine the rate at which vorticity is fed into leading-edge vortices in vortex models. The strength of nascent particles at the leading edge is here computed with the velocity at the edge of the shear layer, formulated in terms of the leading-edge suction parameter (an inviscid parameter from unsteady thin-aerofoil theory). This novel formulation allows postseparation flow behaviour, like vortex sheets dynamics, to be correctly captured. Finally, morphing and vortex modelling are combined to demonstrate the potential of this technique to affect leading-edge vortices: the amount of vorticity produced at the leading edge is modulated by suitably tailoring the shape of the camber line. This research aims to advance our theoretical understanding of the correlation between prescribed deflection at the trailing edge and alteration of flow properties at the leading edge, of interest to the design of flow control strategies inspired by nature.

description: The reaction $^{17}$O($n,α$)$^{14}$C was studied at energies from $E_{cm}=0$ to $E_{cm}=350$ keV using the quasi-free deuteron break-up in the three body reaction $^{17}$O$+d \rightarrow α+ ^{14}$C$+p$, extending the Trojan Horse indirect method (THM) to neutron-induced reactions. It is found that the $^{18}$O excited state at $E^*=8.125 \pm 0.002$ MeV observed in THM experiments is absent in the direct measurement because of its high centrifugal barrier. The angular distributions of the populated resonances have been measured for the first time. The results unambiguously indicate the ability of the THM to overcome the centrifugal barrier suppression effect and to pick out the contribution of the bare nuclear interaction.

description: We study the SU(3) gauge theory with Nf=12 flavors in the fundamental representation by use of lattice simulations with staggered fermions. With a non-improved action we observe a chiral zero-temperature (bulk) transition separating a region at weak coupling, where chiral symmetry is realized, from a region at strong coupling where chiral symmetry is broken. With improved actions, a more complicated pattern emerges, and in particular two first order transitions in the chiral limit appear. We observe that at sufficiently strong coupling the next-to-nearest neighbor terms of the improved lattice action are no longer irrelevant and can indeed modify the pattern observed without improvement. Baryon number conservation can be realized in an unusual way, allowing for an otherwise prohibited oscillating term in the pseudoscalar channel. We discuss the phenomenon by means of explicit examples borrowed from statistical mechanics. Finally, these observations can also be useful when simulating other strongly coupled systems on the lattice, such as graphene.

description: The many examples of integrated farming systems from around Asia that are presented in this technology information kit are not given as models to copy of emulate exactly. Rarely can such complex systems be built from scratch. Many of the technical and budget details will not apply in every case. Rather, examples are given to show what is possible and to stimulate a process of integration on the farm. What other farmers have proven is shared to help people who work directly with farmers to facilitate the addition of new resource flows, the integration of new enterprises, the substitution of external inputs and the rehabilitation of degraded ecosystems. The kit suggests a procedure for evolving farming systems that share the characteristics described herein. It seeks to stimulate people who work directly with farmers develop small-scale farms that provide a reasonable rural livelihood, a clean conserved environment and food, fuel and fiber products.
