description: The Brackett decrement in the Class I source HH100 IR has been observed and analyzed to set constraints on the origin of the IR HI emission in this young object. We have used both low resolution (R ~ 800) observations of the Brackett lines from Brg, to Br24, and medium resolution (R~9000) spectra of the Brg, Br12 and Br13 lines. The dereddened fluxes indicates that the lines remain moderately thick up to high quantum numbers. Moreover, the profiles of the three lines observed in medium resolution are all broad and nearly symmetric, with a trend for the lines at high n-number to be narrower than the Brg, line. With the assumption that the three lines have different optical depths and consequently trace zones at different physical depths, we interprete the observed profiles as evidence that the ionized gas velocity in the HI emitting region is increasing as we move outwards, as expected in an accelerating wind more than in an infalling gas. We have modelled the observed line ratios and velocities with a simplified model for the HI excitation in an expanding circumstellar gas. Such a comparison indicates that the observations are consistent with the emission coming from a very compact region of 4-6 solar radii, where the gas has been already accelerated to velocities of the order of 200 \kms, with an associated mass flow rate of the ionized component of the order of 10^{-7} solar masses per year. This implies that the observed lines should originate either from a stellar wind or from the inner part of a disk wind, providing that the disk inner truncation radius is close to the stellar surface.

description: Supplmentary information for Spatial Analyses of Ediacaran Communities at Mistaken Point
Abstract.— Bedding plane assemblages of Ediacaran fossils from Mistaken Point, Newfoundland, are among the oldest known records of complex multicellular life on Earth (~565 Ma). The in-situ preservation of these sessile, but otherwise deeply enigmatic organisms means that statistical analyses of specimen positions can be used to illuminate their underlying ecological dynamics, including the interactions between taxa. Fossil assemblages on Mistaken Point D and E surfaces were mapped to millimetre accuracy using differentiated GPS. Spatial correlations between ten well defined taxa (Bradgatia, Charniid, Charniodiscus, Fractofusus, Ivesheadiomorphs, Lobate Discs, Pectinifrons, Plumeropriscum, Hiemalora and Thectardis), were identified using Bayesian Network Inference (BNI), and then described and analysed using Spatial Point Process Analysis. BNI found that the E surface community had a complex web of interactions and associations between taxa, with all but one taxon (Thectardis) interacting with at least one other. The unique spatial distribution of Thectardis supports previous, morphology-based arguments for its fundamentally distinct nature. BNI revealed that the D surface community showed no inter-specific interactions or associations, a pattern consistent with a homogeneous environment. On the E surface, all six of the abundant taxonomic groups (Fractofusus, Bradgatia, Charniid, Charniodiscus, Thectardis and Plumeropriscum) were each found to have an unique set of interactions with other taxa, reflecting a broad range of underlying responses. Four instances of habitat associations were detected between taxa, of which two (Charniodiscus - Plumeropriscum, and Plumeropriscum - Fractofusus) led to weak competition for resources. One case of pre-emptive competition between Charniid and Lobate discs was detected. There were no instances of inter-specific facilitation. Ivesheadiomorphs interactions mirror those of Fractofusus and Charniodiscus, identifying them as a form-taxonomic grouping of degradationally homogenized taphomorphs. The absence of increased fossil abundance in proximity to these taphomorphs argues against scavenging/saprophytic behaviours dominating the E surface community.

description: Electron interferometry with quantum Hall edge channels holds promise for probing and harnessing exotic exchange statistics of non-Abelian anyons. In semiconductor heterostructures, however, quantum Hall interferometry has proven challenging and often obscured by charging effects. Here we show that high-mobility monolayer graphene equipped with a series of gate-tunable quantum point contacts that act as electron beam-splitters provides a model system to perform Fabry-Pérot quantum Hall interferometry. We observe high-visibility Aharonov-Bohm interference free of charging effects and widely tunable through electrostatic gating or magnetic field, in remarkable agreement with theory. A coherence length of $\mathbf{10 \,μm}$ at a temperature of $0.02$ K allows us to further achieve coherently-coupled double Fabry-Pérot interferometry. Our results open a new avenue for quantum Hall interferometry and the exploitation of topological excitations for quantum computation.

description: The exact analytical solution of Maxwell equations for a Bessel light beam scattered by a sphere is found. Scattered power, stored energy and a generalized Q factor as a function of frequency, the sphere radius, permittivity, and the Bessel beam angle are found. On the base of this solution, modes and pseudo-modes of a dielectric sphere are extracted by calculation of the generalized Q factor. It is shown that an appropriate choice of Bessel beam parameters can provide excitation of a single given mode and an unlimited value of the radiative Q factor of pseudo-modes.

description: Since food consumption contributes significantly to greenhouse gas emissions it is important field of action for consumer engagement. In this context, the present article looks into the question if carbon footprint labels are a suitable mean to foster climate-friendly food purchase behavior. By means of a mixed methods approach comprising choice experiments and qualitative face-to-face interviews European consumers’ preferences and willingness to pay for carbon footprint labels compared to other sustainability labels as well as socio-psychological barriers for climate-friendly consumption are explored. The results reveal that consumers are prepared to pay a price premium for carbon footprint labels but that label skepticism and fatigue as well as a lack in awareness about the impact of food production and consumption on climate change are major barriers for climate-friendly purchase behavior. Information provision in form of carbon footprint labels can only be one part of the solution. Political engagement and engagement by the retail are incremental for success.

description: The observation of coherent elastic neutrino nucleus scattering (CE$ν$NS) by the COHERENT collaboration in 2017 has opened a new window to both test Standard Model predictions at relatively low energies and probe new physics scenarios. Our investigations show, however, that a careful treatment of the statistical methods used to analyze the data is essential to derive correct constraints and bounds on new physics parameters. In this manuscript we perform a detailed analysis of the publicly available COHERENT CsI data making use of all available background data. We point out that Wilks' theorem is not fulfilled in general and a calculation of the confidence regions via Monte Carlo simulations following a Feldman-Cousins procedure is necessary. As an example for the necessity of this approach to test new physics scenarios we quantify the allowed ranges for several scenarios with neutrino non-standard interactions. Furthermore, we provide accompanying code to enable an easy implementation of other new physics scenarios as well as data files of our results.

description: This Background Paper defines indirect effects of migration on development as the effects on specific outcomes of changes in norms, values and perceptions that are brought about by the migratory experience. Specifically, we estimate: (i) the indirect effects on girls’ enrolment from changes in gender norms brought about by migration, and (ii) the effects on civic and political participation from changes in perception of the quality of governance brought about by migration.

Key Takeaways

The number of migrants in an area has a positive effect on civic participation and girls’ secondary enrolment.

Migratory experiences affect norms and values, which, in turn, increase civic participation and girls’ secondary enrolment.

The true effects of migration at the community level are often underestimated, because effects extend beyond migrant households.

description: The Brazilian Coffee Agribusiness system has been modified over the last years. An evidence is the outsourcing contracts in agricultural mechanization of harvesting services. Brazilian coffee growers have replaced their own machineries for specialized services firms. The Coase (1937)'s make or buy paradigm sheds light the decision of farmers of the coffee chain with the investment lens. The investigation analyzes the determinants of outsourcing contracts in the transaction of harvesting mechanization in the agribusiness system of coffee in Brazil based on a quantitative approach through a probit regression with 105 Brazilian coffee growers’ interviews. The results validated the path dependence aspect and the hypothesis of the asset specificity and uncertainty of the efficient alignment argument of the Transaction Cost Economics, pointing out the high level of education of the farmer and the adoption of contracts as a way of coordinating other transactions as determinants of the outsourcing contracts of the transaction of harvesting mechanization. The study brought a change in coffee grower’s profile to a modern pattern of decision-making with three different institutional arrangements for the transaction of harvesting mechanization: total vertical integration, tapped vertical integration and outsourcing contracts or only outsourcing contracts.

description: Elie Wiesels wohl meistgelesenes Werk ist sein Überlebensbericht Die Nacht, in dem er die Deportation aus seiner Heimatstadt Sighet nach Auschwitz, dann ins Lager Buna/Monowitz und schließlich den Todesmarsch nach Buchenwald und seine Befreiung schildert. Dieses Zeugnis erschien in der deutschen Übersetzung von Curt Meyer-Clason erstmals 1962.2 Vorlage war der von Wiesel selbst verfasste französische Text La Nuit (1958), der bereits 1960 von Stella Rodway ins Englische übertragen worden war. Zu diesem französischen Text existiert jedoch noch eine mehr als doppelt so umfangreiche jiddische Vorversion unter dem Titel …un di welt hot geschwign (1955/56), erschienen als Nr. 117 in der Reihe Dos pojlische jidntum. 3 Für das Projekt der deutschsprachigen Gesamtausgabe der Elie-Wiesel-Werke wird im ersten Schritt an der Übersetzung von …un di welt hot geschwign ins Deutsche gearbeitet. Zwar soll dazu ein noch ausführlicheres, 862 Seiten starkes jiddisches Manuskript existieren oder existiert haben, dieses wird der Forschung wohl jedoch unzugänglich bleiben.4 Der Historiker Joel Rappel 5 stieß bei seinen Recherchen zur Entstehungsgeschichte von Die Nacht auf ein hebräischsprachiges Manuskript von 150 Seiten, das mit dem Hinweis »first draft« (erster Entwurf) markiert war. 6 Diese handschriftliche Version von Elie Wiesels Bericht soll laut Rappel bereits vor der maschinengeschriebenen jiddischen Version …un di welt hot geschwign entstanden sein.7 Wiesels Autobiographie Alle Flüsse fließen ins Meer… gibt ebenfalls einen Hinweis darauf: »Ich bleibe während der ganzen Überfahrt in meiner Kabine und schreibe auf Jiddisch an meiner Erzählung über die Zeit im Konzentrationslager. Ich hatte mit dem Bericht schon vor einigen Monaten auf Hebräisch begonnen und ihn, ich weiß nicht mehr, aus welchem Grund, Yaffah zu lesen gegeben, einer Kollegin, die für eine israelische Kinozeitschrift arbeitet.« 8 Allerdings bleibt unklar, ob der hebräische Text vor der Arbeit an …un di welt hot geschwign beendet worden war und was die von Wiesel genannte Kollegin mit seinem Text gemacht hat. Joel Rappel datiert das von ihm gefundene hebräische Manuskript auf das Jahr 1954 und vermutet, dass Elie Wiesel seinen hebräischen Text der israelischen Zeitung Jediot Achronot angeboten hat, für die er schon seit 1948/49 schrieb.9 Das Manuskript wurde in kurzen Abschnitten von höchstens zwei bis vier Seiten verfasst. Dies entspräche der üblichen Länge der Artikel, die Wiesel dorthin ablieferte. Erst Ende des vergangenen Jahres hat Rappel der Öffentlichkeit ein weiteres Textfragment, diesmal der französischen Version La Nuit, präsentiert. 10 Es handelt sich dabei um das ursprünglich erste Kapitel von La Nuit, das bei der Überarbeitung herausgestrichen worden war.

description: The aim of this paper is to explore the diversity of farmers’ relationship to the networks that make up the knowledge and innovation systems. We approach farmer’s knowledge diversity through the development of a typology based on a principal component analysis (PCA) of Norwegian farmers. The analysis indicates a preliminary typology of farmers where the main types are: 1) the self-confident farmers; 2) the knowledge-seeking farmers; 3) the knowledge-purchasing farmers; 4) the experienced farmers; 5) the collective- knowledge farmers; and, 6) the well-educated farmers. We discuss how extension service may improve communication, knowledge services, and knowledge networks.
Study of lymphocyte development from embryonic stem cells in vitro

description: Embryonic stem (ES) cells have been shown to differentiate to all hematopoietic lineages. However, lymphocyte development from murine ES cells has not been fully investigated. In this thesis, the developmental pathway of natural killer (NK) lymphocytes from ES cells was investigated, using a multi-step in vitro ES cell differentiation system. ES cells were induced to differentiate into embryoid bodies (EBs). CD34⁺ EB cells were isolated and cultured on OP9 stroma with a cocktail of cytokines to generate cells; termed ES-derived hematopoietic progenitors (ES-HPs). EB cell subsets as well as ES-HPs were tested for NK, T, B, and myeloid lineage potentials using lineage specific differentiation cultures. ES-HPs derived from CD34⁺ EB cells appeared to be heterogeneous and contained NK, T, B and myeloid potentials. At the EB level, lymphoid potential was found in CD34⁺CD45⁻ EB cell subset, while CD34⁺CD45⁺ EB cells had only myeloid but not lymphoid potential. CD34⁺CD45⁻ EB cells gave rise to CD45⁺ Mac-1⁻Ter119⁻(Lin⁻) ES-HPs, which were highly enriched for NK progenitors, but also had other lineage potentials. The NK progenitors among ES-HPs lacked CD122, a marker for NK lineage committed precursors, but they acquire CD122 as they differentiate along the NK lineage. To further enrich lymphoid progenitors among CD45⁻ EB cells, EB cell populations were dissected according to several surface markers and tested for myeloid and lymphoid lineage potentials. Hematopoietic progenitors with lymphoid potential in EBs were found to be CD45⁻CD34⁺c-kit⁺CD41⁺CD31⁺Flk-1⁺. As they differentiate in vitro into more mature hematopoietic progenitors, they slowly acquire CD45 and lose Flk-1 and CD41 expression while retaining erythroid/myeloid and lymphoid potentials. This study suggests that hematopoietic progenitors in EBs are similar to immature embryonic hematopoietic stem cells (HSCs) and they differentiate into more mature type HSCs in vitro.
title: Investigating The Possible Role Of Regulatory T Cells In Suppressing DTwP And Measles-Vaccine Induced Responses In 9 Month-Old Gambian Infants
Creators: name: Ndure, Yai Jorjoh
Publisher: name: The Open University

description: The majority of deaths in children under five are attributed to infections, with neonates and young infants being the most susceptible. The immune system of the newborn is adapted to protect the fetus from infections and avoid harmful inflammation, characterized by limited Th1 immunity and skewed towards Th2 and immunoregulatory responses. This results in high susceptibility to infections and impaired responses to vaccines. Regulatory T cells (Tregs) control pro-inflammatory responses and are therefore important in maintaining a fine balance of immune responses during infections. Tregs are high and functional in neonates, but their precise role in controlling vaccine immunogenicity is not known. I hypothesised that circulating Tregs at vaccination can limit subsequent vaccine-induced cellular and humoral responses, and that functional Tregs are induced by vaccination in infants. The work in this thesis involves the characterization of Tregs before and after measles and Diphtheria, Tetanus and whole cell pertussis combined (DTwP) vaccination, and association with functional readouts, vaccine-specific humoral and cellular responses. I found that CD4+FOXP3+CD127lo Tregs significantly declined overtime, with this subset and the CD4+CD25hiFOXP3+ Treg subsets inversely correlating with the measles antibodies following vaccination. This supports a functional role for Tregs in controlling the humoral response to measles but not for DTwP vaccination. We also observe an induction of CD4+IL-10+ T cells following measles vaccination. Further evaluation of these cells showed that they were mainly IL-4- and IFN-γ-, excluding the possibility that these may be Th1 or Th2 cells, and suggesting that these may be Tr1 cells induced as part of a homeostatic control mechanism following MV. Further evaluation of the role of Tregs in vaccine immunogenicity in infants is warranted.

description: There is a strong interplay between root causes, policies, and networks driving migration aspirations and out- migration intensity among 26 MIGNEX research areas in 10 African and Asian countries.

Key Takeaways

No single root cause is identified as strictly necessary nor sufficient for driving migration aspirations or actual migration behaviour, reflecting the complexity of migration determinants.

Elevated international migration aspirations are shaped by a nuanced interplay of socio-cultural and political-economic factors, where a culture of migration and limited involvement of migration- related policies assume pivotal roles.

A firmly ingrained culture of migration and strong migration aspirations are central, yet not sufficient on their own in generating high out-migration. Complementary local factors give rise to distinctive out-migration patterns.

description: We provide a compact review on recent developments on axion $F(R)$ gravity. The axion field is a string theory originating theoretical particle that is a perfect candidate for low-mass particle dark matter. In this review we present how a viable inflationary phenomenology and a viable late-time evolution can be described by an axion $F(R)$ gravity theory, in which the $F(R)$ gravity part can drive in a geometric way the inflationary and the late-time era, and the axion field behaves as dark matter, with its energy density $ρ_a$ behaving as a function of the scale factor as $ρ_a\sim a^{-3}$. We also briefly discuss the effect of a non-trivial axion Chern-Simons coupling on the inflationary phenomenology of the $R^2$ model. Finally, we briefly discuss the effects of a non-minimal coupling of the axion field with the curvature on neutron stars, and also the propagation of gravity waves in Chern-Simons axion gravity.

description: Migration can affect households through various channels: the absence of a person, receiving remittances or learning of new ideas. Our analysis focuses on how these different aspects of migration influence well-being across five dimensions and specific indicators in 25 research areas, showing that migration influences multidimensional household well-being and development in a diversity of ways that are not always straightforward.

Key Takeaways

Having a return migrant and receiving remittances are associated with higher participation in groups and social capital, showing that the effects of migration go beyond only financial ones.

The aggregated analysis hides interesting and diverse findings within specific indicators or local areas, strongly pointing to the value of disaggregation.

“Social remittances” that households receive can be just as – or more – important, alongside, or instead of, financial remittances.

description: On the basis of spectrophotometric observations we reconstruct the accretion disk of the eclipsing novalike cataclysmic variable RW Tri in the wavelength region 3600-7000 A. We find a radial temperature profile that is, on average, consistent with that expected on the basis of the theory of optically thick, steady state accretion disks and infer a mass-accretion rate in RW Tri of \~10e-8 solar masses per year. The line emission is dominated by two areas: one around the hot-spot region and one near the white dwarf. Both emission regions have appreciable vertical extension, and seem to be decoupled from the velocity field in the disk. In our observations RW Tri shows a number of features that are characteristic of the SW Sex sub-class of novalike stars. The appearance of a novalike system as a UX UMa/RW Tri or SW Sex star seems to be mainly governed by the mass-transfer rate from the secondary at the time of observation.

description: We study 4D systems in which parameters of the theory have position dependence in one spatial direction. In the limit where these parameters jump, this can lead to 3D interfaces supporting localized degrees of freedom. A priori, this sort of position dependence can occur at either weak or strong coupling. Demanding time-reversal invariance for $U(1)$ gauge theories with a duality group $Γ\subset SL(2,\mathbb{Z})$ leads to interfaces at strong coupling which are characterized by the real component of a modular curve specified by $Γ$. This provides a geometric method for extracting the electric and magnetic charges of possible localized states. We illustrate these general considerations by analyzing some 4D $\mathcal{N} = 2$ theories with 3D interfaces. These 4D systems can also be interpreted as descending from a six-dimensional theory compactified on a three-manifold generated by a family of Riemann surfaces fibered over the real line. We show more generally that 6D superconformal field theories compactified on such spaces also produce trapped matter by using the known structure of anomalies in the resulting 4D bulk theories.

description: »Hunger als ständiger Begleiter« von Angst, Verzweiflung, Tod und Elend sind die charakteristischen Stichworte, die sich durch die 30 Textdokumente der Jüdischen Gemeinde Kreuzlingen, des Schweizerischen Israelitischen Gemeindebundes, aber vor allem durch die Briefe und Postkarten aus den französischen Internierungscamps Gurs, Noé, Pontacq, Récebédou, Rivesaltes, Les Mittes an die jüdische Gemeinde Kreuzlingen ziehen. Sehr eindrücklich ist die Sammlung der Briefe von Rosa Schriesheimer. Die Frage nach dem Warum wird in dem Beitrag von Margot Wicki-Schwarzschild thematisiert, die selbst Betroffene der Deportation der jüdischen Bevölkerung aus Südwestdeutschland am 22.10.1940 war. Die historische Einordnung von Erhard Roy Wiehn der Ereignisse der Deportation nach Gurs in Südfrankreich nahe der spanischen Grenze macht die Ungeheuerlichkeit offenbar, mit der das NSRegime gegen die jüdische Bevölkerung vorging. Die Briefzeugnisse sind z.T. erschütternd, und für die heutigen Leser_innen wird deutlich, dass sich diese Geschichte(n) nicht auf einem fremden Stern abgespielt hat/haben, sondern im Herzen Mitteleuropas. Insgesamt wurden aus Baden und der Pfalz 6.504 Menschen jüdischer Zugehörigkeit deportiert, die Unvorstellbares mitmachen mussten; Rosa Schriesheimer schrieb am 17.3.1943 aus Gurs: »Ich will und darf den Mut nicht sinken lassen, und will ich das Gottvertrauen nicht verlieren.« (S. 13) Vier Jahre bekamen die Deportierten aus der Schweiz Unterstützung, die unter z.T. massiv erschwerten politischen Bedingungen erbracht wurde. »Auch rund 75 Jahre später sind diese Briefe und Postkarten noch traurige Zeugnisse des Leidens und der Verzweiflung völlig unschuldiger Opfer, immerhin jedoch im Kontext von Dokumenten selbstloser Hilfsbereitschaft. « (S. 16) In Gurs herrschten »unendlicher Hunger, Kälte, materielle Not und seelisches Elend.« (S. 238) Ab dem 5.8.1942 wurden diejenigen, die die Verhältnisse in Gurs überstanden hatten, fast vollzählig in die »Todeslager« nach Polen gebracht (S. 240). Bitter wird kommentiert: »Die Staatsraison von Vichy kannte keine Menschlichkeit.« (S. 241)

description: The problem of the optimal approximation of circular arcs by parametric polynomial curves is considered. The optimality relates to the Hausdorff distance and have not been studied yet in the literature. Parametric polynomial curves of low degree are used and a geometric continuity is prescribed at the boundary points of the circular arc. A general theory about the existence and the uniqueness of the optimal approximant is presented and a rigorous analysis is done for some special cases for which the degree of the polynomial curve and the order of the geometric smoothness differ by two. This includes practically interesting cases of parabolic $G^0$, cubic $G^1$, quartic $G^2$ and quintic $G^3$ interpolation. Several numerical examples are presented which confirm theoretical results.
Spoke formation under moving plasma clouds

description: Goertz and Morfill (1983) propose that spokes on Saturn's rings form under radially moving plasma clouds produced by meteoroid impacts. We demonstrate that the speed at which a plasma cloud can move relative to the ring material is bounded from above by the difference between the Keplerian and corotation velocities. The radial orientation of new spokes requires radial speeds that are at least an order of magnitude larger than this upper limit, thus the model advanced by Goertz and Morfill fails to make radial spokes.

description: When a system consisting of many interacting particles is set rotating, it may form vortices. This is familiar to us from every-day life: you can observe vortices while stirring your coffee or watching a hurricane. In the world of quantum mechanics, famous examples of vortices are superconducting films and rotating bosonic $^4$He or fermionic $^3$He liquids. Vortices are also observed in rotating Bose-Einstein condensates in atomic traps and are predicted to exist for paired fermionic atoms. Here we show that the rotation of trapped particles with a repulsive interaction leads to a similar vortex formation, regardless of whether the particles are bosons or (unpaired) fermions. The exact, quantum mechanical many-particle wave function provides evidence that in fact, the mechanism of this vortex formation is the same for boson and fermion systems.

title: The History of Water and Other Associated Volatiles in Howardite-Eucrite-Diogenite Meteorites
Creators: name: Barrett, Thomas
Publisher: name: The Open University

description: Recent in situ measurements of volatiles (H2O, Cl and F), particularly in lunar and martian samples, have changed our understanding of the volatile inventory of the inner Solar System. Whilst this has provided a wealth of data for these planetary bodies, currently little is known about the history of volatiles in other bodies in the inner Solar System. The howardite, eucrite, diogenite (HED) meteorites form the largest suite of rocks representing a differentiated basaltic asteroid (4 Vesta) and are some of the oldest igneous rocks in the Solar System. Understanding their volatile histories, therefore, can help us to constrain some of the processes that operated on Vesta early in Solar System history.

 Using the NanoSIMS 50L, six eucrites were analysed for their apatite H2O abundance and hydrogen isotopes, whilst seven eucrites (five of which were also investigated for H) were analysed for their apatite Cl content and isotopic composition. Apatite H2O abundances range from ~ 30 to ~ 3500 ppm and are associated with a weighted average δD value of - 34 ± 67 ‰. No systematic variations or correlations are observed in H2O abundance or δD value with eucrite geochemical trend or metamorphic grade. These results are comparable to published literature and confirm the striking homogeneity in the H-isotopic composition of water in eucrites, and are consistent with a common source of water in the inner Solar System. Chlorine abundance in apatite ranges from ~ 25 to 4900 ppm and the δ37Cl values range from – 3.98 to + 35.6 ‰. Samples with lower H2O content typically were enriched in δ37Cl, however, no obvious correlation between δ37Cl and δD values is seen. Cl isotope fractionation is likely to have occurred for some samples via magmatic degassing of ZnCl2. The observed variation in Cl isotopes, particularly the residual eucrites, however, remains enigmatic.

description: The "Certified Organic System" is a production and marketing system that requires thought and planning. Planned diversification and good management principles can steer production away from monoculture agriculture and a dependence on chemicals pot1mtially hazardous to the environment. To practice this system the farmer must concentrate on improved management and gearing this management to production of a quality product for a known market utilizing techniques to maximize production and minimize destructive impact on the environment.
