Neighborhood Groups vs. Business Developers in Durham: Expressway Politics in the Scarce Energy Age
Creators: name: Luebke, Paul
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1981

description: The East-West Expressway in Durham, North Carolina, assumed by its businessmen supporters to be completed routinely during the early 1980s, has been stalled primarily by a coalition of white and black neighborhood groups aligned against it. The Coalition for Expressway Alternatives delayed the project in February 1979 by persuading the Durham City Council to reverse its earlier votes and oppose the completion of the highway. The future of the highway at this writing is still in doubt for a variety of reasons: the national energy issue, a revised federal domestic policy which opposes suburban development at the expense of the central city, rising road construction costs and civil rights issues. At issue is a 2.1 mile westward expressway extension which would complete a crosstown highway first begun in 1966. The case for completing the expressway is local traffic congestion in West Durham, and the embarassment of not finishing a project begun fifteen years ago. Finishing the road would also provide a convenient connection for through-city traffic on Interstate highways 85 and 40. However, completing the highway would require relocating 200 families in a low-income black neighborhood known as the Crest Street community, and might also damage the city's economy more than help it. This paper examines the values of Durham's businessmen (proponents of the extension) and the neighborhood alliance (opponents of the extension), highlighting their contrasting positions on numerous issues facing most American cities in the 1980s. The Durham expressway controversy is significant for at least three reasons. First, the timeframe of the conflict demonstrates the reaction of both sides to our energy problem. Second, the white-black coalition against the white business community introduces a political cleavage based on economic self-interest which could either replace or augment the perennial Southern racial cleavage. Third, North Carolina state officials have unequivocally supported the business developers' position. Unlike the situation of neighborhood groups during the Boston expressway conflict a decade ago, 2 Durham's neighborhood coalition found that its Democratic Governor and his Secretary of Transportation were unimpressed by arguments against the expressway, viewing the Coalition as "liberal" and therefore insignificant in a state dominated by conservatives. The battle between businessmen and neighborhood groups arose because of differing views on two questions: how the city of Durham can prosper in the next two decades; and how important the automobile is for the city's future. Detailed answers to these questions appear below and outline the value-systems of expressway proponents and opponents. The response by these two groups to the energy issue is also examined.

description: A self-consistent expression for the surface recombination velocity $S$ and the surface Fermi level unpinning energy as a function of light excitation power ($P$) is presented for n- and p-type semiconductors doped above the 10$^{16}$ cm$^{-3}$ range. Measurements of $S$ on p-type GaAs films using a novel polarized microluminescence technique are used to illustrate two limiting cases of the model. For a naturally oxidized surface $S$ is described by a power law in $P$ whereas for a passivated surface $S^{-1}$ varies logarithmically with $P$. Furthermore, the variation in $S$ with surface state density and bulk doping level is found to be the result of Fermi level unpinning rather than a change in the intrinsic surface recombination velocity. It is concluded that $S$ depends on $P$ throughout the experimentally accessible range of excitation powers and therefore that no instrinsic value can be determined. Previously reported values of $S$ on a range of semiconducting materials are thus only valid for a specific excitation power.

description: A thorough analysis of the dynamics in a deterministic optical rocking ratchet (introduced in A. V. Arzola et al., Phys. Rev. Lett. 106, 168104 (2011)) and a comparison with experimental results are presented. The studied system consists of a microscopic particle interacting with a periodic and asymmetric light pattern, which is driven away from equilibrium by means of an unbiased time- periodic external force. It is shown that the asymmetry of the effective optical potential depends on the relative size of the particle with respect to the spatial period, and this is analyzed as an effective mechanism for particle fractionation. The necessary conditions to obtain current reversals in the deterministic regime are discussed in detail.

description: To satisfy the requirements of performance-based design methods for a large number of earthquake signals that contain a series of variable random variables, the generation of artificial seismic ground motion is necessary. To statistics amplitudes’ instability in the time domain, 500 recorded earthquakes have been divided into 5 groups by D5-95 durations and are statistically analyzed. For each D5-95 earthquake group, its standard time-domain enhancement-attenuation process is described as the edge envelope curve, and the representativeness of the curve is valued as the coverage rate. Comparing response spectrums before and after multiplying with edge envelopes functions of 6000 initial artificial earthquakes that are generated by inverse Fourier process with different intensities and D5-95 durations, their spectrums are well-matched. This newly proposed method is proven to be able to generate artificial earthquake signals that resemble natural amplitudes and time-domain characteristics and maintain the desired frequency domain response. © 2021 THE AUTHORS

description: We revisit the relativistic restricted two-body problem with spin employing a perturbation scheme based on Lie series. Starting from a post-Newtonian expansion of the field equations, we develop a first-order secular theory that reproduces well-known relativistic effects such as the precession of the pericentre and the Lense-Thirring and geodetic effects. Additionally, our theory takes into full account the complex interplay between the various relativistic effects, and provides a new explicit solution of the averaged equations of motion in terms of elliptic functions. Our analysis reveals the presence of particular configurations for which non-periodical behaviour can arise. The application of our results to real astrodynamical systems (such as Mercury-like and pulsar planets) highlights the contribution of relativistic effects to the long-term evolution of the spin and orbit of the secondary body.

The result is subsequently applied to the evaluation of the corresponding imaginary time correlator, and its use in the context of sum rules is discussed. Our hope is that the calculation will eventually find use in the nonperturbative determination of the shear viscosity of the theory.

description: The comparison of the g-factors of the proton and the antiproton is a stringent test of CPT invariance. The state-of-the-art method for the determination of the (anti-)proton's g-factor is the application of the continuous Stern-Gerlach effect. With this method, precisions in the low parts per billion regime could be achieved. However, preparation times for cold enough particles are on the order of minutes to hours. The implementation of sympathetic cooling using a co-trapped atomic ion could lead to preparation times in the milliseconds regime. Furthermore, the applicability of sympathetic cooling would enable an alternative readout scheme using quantum logic methods. This thesis presents a Penning trap system that is designed for ground state cooling, adiabatic transport, and motional coupling of single 9Be+ ions. It has been built in a modular manner, giving the option of adapting it for motional coupling and sympathetic cooling of single (anti-)protons. In the course of this work, the prerequisites for motional coupling of 9Be+ ions have been fulfilled: A cloud of 9Be+ ions was cooled to a temperature of 1.7~mK applying Doppler cooling. The achieved temperature is about three times the Doppler limit which is 0.5~mK for beryllium ions. Furthermore, a scheme for reproducible loading of the trap and reducing the particle number was developed. Finally, first transport in our apparatus was demonstrated with clouds of beryllium ions. The method used for that is directly applicable to single ions. The results of this work pave the way towards adiabatic transport of single 9Be+ ions, which is crucial for sympathetic cooling of (anti-)protons in a double-well potential as well as for implementing quantum logic spectroscopy with single (anti-)protons.

description: The spread of the deadly disease Coronavirus has had a negative impact on every aspect of human life, including the education sector with no exception. As a preventive measure, Governments worldwide announced lockdown & closure of the educational institutions, promote a drastic change in the education environment, from conventional classroom-based to online interaction-based. As the second wave of the pandemic strikes India with a tsunami of cases, LIS professionals serve as front-line workers to keep the educational system functioning without interruption. The present study tried to analyze the performance of LIS professionals during this nightmare with thousands of barriers, like limited e-content, internet speed, availability of insufficient devices, inadequate technical knowledge, unfamiliar online learning, lack of social & personal relationship, financial crisis and physical & psychological health issues. An online survey was conducted with a sample of N=1000, including 500 library staff & 500 teaching staff, to find the answers to the research questions. According to the study findings, employees’ efficiency, social & personal relationships and financial situations were negatively influenced by lockdown during COVID-19, although they tried hard to complete their goals and serve the community with authentic information & knowledge.

description: Context. Blazars are powerful active galactic nuclei (AGNs) radiating prominently in the whole electromagnetic spectrum, from the radio to the X-ray and gamma-ray bands. Their emission is dominated by synchrotron and inverse-Compton radiation from a relativistic jet originating from an accreting central supermassive black hole. The object IGR J12319-0749 has recently been identified as a soft gamma-ray source with the IBIS instrument of the INTEGRAL satellite, coincident with a quasar at high redshift (z=3.12). Aims. We studied the radio structure of IGR J12319-0749 to strengthen its blazar identification by detecting a compact radio jet on the milli-arcsecond (mas) angular scale, and to measure its astrometric position accurate to mas level. Methods. We used the technique of electronic very long baseline interferometry (e-VLBI) to image IGR J12319-0749 with the European VLBI Network (EVN) at 5 GHz on 2012 June 19. Results. IGR J12319-0749 (J1231-0747) is a compact radio source, practically unresolved on interferometric baselines up to ~136 million wavelengths. The estimated brightness temperature (at least ~2 x 10^12 K) indicates that the radio emission of its jet is Doppler-boosted. The accurate position of the compact radio source is consistent with the positions measured at higher energies.

description: We present sub-arcsecond observations toward the massive star forming region G75.78+0.34. We used the Very Large Array to study the centimeter continuum and H2O and CH3OH maser emission, and the Owens Valley Radio Observatory and Submillimeter Array to study the millimeter continuum and recombination lines (H40alpha and H30alpha). We found radio continuum emission at all wavelengths, coming from three components: (1) a cometary ultracompact (UC) HII region with an electron density 3.7x10^4 cm^{-3}, excited by a B0 type star, and with no associated dust emission; (2) an almost unresolved UCHII region (EAST), located 6 arcsec to the east of the cometary UCHII region, with an electron density 1.3x10^5 cm^{-3}, and associated with a compact dust clump detected at millimeter and mid-infrared wavelengths; and (3) a compact source (CORE), located 2 arcsec to the southwest of the cometary arc, with a flux density increasing with frequency, and embedded in a dust condensation of 30 Msun. The CORE source is resolved into two compact and unresolved sources which can be well-fit by two homogeneous hypercompact HII regions each one photo-ionized by a B0.5 ZAMS star, or by free-free radiation from shock-ionized gas resulting from the interaction of a jet/outflow system with the surrounding environment. The spatial distribution and kinematics of water masers close to the CORE-N and S sources, together with excess emission at 4.5 mum and the detected dust emission, suggest that the CORE source is a massive protostar driving a jet/outflow.

description: We study the control of coherent light propagation through multiple-scattering media in the presence of measurement noise. In our experiments, we use a two-step optimization procedure to find the optimal incident wavefront. We conclude that the degree of optimal control of coherent light propagation through a multiple-scattering medium is only determined by the number of photoelectrons detected per single speckle spot. The prediction of our model agrees well with the experimental results. Our results offer opportunities for imaging applications through scattering media such as biological tissue in the shot noise limit.

Year: 2003

description: This article reviews the current context of manufactured housing within the nation and North Carolina in particular. Over the past decade, there has been significant growth in the number of North Carolina's mobile home residences, serving as an affordable housing option for low-to-moderate income households. Despite advances in the mobile home industry, five main sources of lingering problems within the industry are identified: financing, land use, quality of construction and installation, equity-building, and consumer protection. This review is intended to familiarize practitioners with issues related to manufactured housing, and calls for broad reform in the areas of consumer and industry education, state policy, financing programs, and public perception as a means to ensure that manufactured housing can serve as a viable option for affordable housing.
Planners Get Results: Old New Bern Gets a New Look

Year: 1983

description: Settled in 1710 by German Palatines and Swiss Colonists, New Bern became a major port and mercantile center because of its protected waters and lack, of tidal fluctuation. Its importance as a port declined, however, with the advent of railways and improved roads during the early 1900s. The central business district grew slowly; later, a shopping mall attracted merchants to the outskirts of the city. The viability of the commercial heart of the community was threatened, and the tax base eroded as more stores became vacant. Recognizing the importance of downtown New Bern and the architectural and historical heritage of the older parts of the city, the community began taking steps to solve some of these problems. The following narrative describes several ways the New Bern Planning and Community Development Department became a part of the downtown revitalization process.

description: Xanthomonas oryzae pv. oryzae (Xoo) sind pflanzenpathogene Bakterien, die in einigen Reisanbaugebieten zu schweren Ernteeinbußen führen. TALEs sind Virulenzfaktoren aus Xoo und fungieren als Transkriptionsaktivatoren in pflanzlichen Zellen. Mit Hilfe von bis zu 20 TALEs pro Stamm, verändert Xoo die pflanzliche Genexpression zu seinen Gunsten. Jedoch sind nur für wenige TALEs induzierte Zielgene bekannt. Im Rahmen dieser Arbeit wurden vier verschiedene Xoo-Stämme sequenziert und das TALE-Repertoire analysiert. Dabei wurden TALEs in Klassen eingeteilt und eine einheitliche Nomenklatur etabliert. Mit Hilfe einer RNA- seq-Analyse wurden neue potentielle Zielgene in Reis für 16 TALEs identifiziert. Dabei konnte das Gen Os03g03034, welches für eine Flavonol-Synthase kodiert, als potentielles Zielgen des TALEs TalAQ identifiziert werden. Durch die Induktion dieses Gens könnte Xoo pflanzliche Abwehrreaktionen unterdrücken. Um einer Infektion von Xoo entgegenzuwirken, ist es möglich die TALE-Bindestelle in Promotoren von Suszeptibilitätsgenen zu mutieren. Auf diese Weise können die TALEs nicht länger binden und rezessive Resistenzgene erstellt werden. Im Rahmen dieser Arbeit wurden TALE-Nukleasen (TALEN) erstellt, um die Bindestellen der natürlichen TALEs AvrXa7 und TalC zu mutieren. Somit konnte der Promotor eines der wichtigsten Suszeptibilitätsgene von Reis, OsSWEET14, durch unsere Kooperationspartner vom IRD und CIRAD in Montpellier, erfolgreich an zwei verschiedenen Stellen editiert werden. Drei der entstandenen Reislinien (sweet14-10, sweet14-11 und sweet14-32) wurden in dieser Arbeit, mit Hilfe von Inokulationsexperimenten, analysiert. Die durchgeführten Experimente weisen darauf hin, dass die Reislinien gegenüber Infektionen von Xoo-Stämmen mit den TALEs AvrXa7 bzw. TalC resistent sind. Somit konnten erfolgreich resistente Reispflanzen generiert werden. TALEN funktionieren als Paar, wobei zwei TALEN-Proteine in einer tail-to-tail-Orientierung an die DNA binden. So können die FokI-Monomere dimerisieren und die DNA spalten. Im Rahmen dieser Arbeit wurden, zur Vereinfachung dieser Technologie, single-chain TALEN (scTALEN) erstellt. Dafür wurden an einen TALE zwei heterodimerisierende FokI-Monomere fusioniert. Es konnte nachgewiesen werden, dass die scTALEN die DNA in vitro effizient spalten. Somit konnte eine neue Art benutzerdefinierbarer Restriktionsenzyme erstellt werden, welche es möglich machen, eine beliebige DNA-Sequenz an einer spezifischen Stelle mit einem definierten vier Basenpaar-Überhang zu spalten. Die Aktivität der scTALEN konnte in vitro, bisher jedoch nicht in vivo, detektiert werden. In Zukunft könnte diese Technik zum vereinfachten Genome Editing weiterentwickelt werden.

description: Kannapolis is a thriving city of 43,115 people located along the 1-85 corridor in the Charlotte region of North Carolina. It began as a mill community in 1906 when J.W. Cannon purchased 808 acres of former cotton fields and began construction of “Cannon’s model mill town,” which ambitiously became known as Kannapolis. In its first year of operation, Cannon built two manufacturing plants and 75 homes for carpenters and construction workers. Shortly thereafter, 75 additional homes were built for the first wave of textile workers who came to the area with the promise of new opportunities. By 1920, the population of the community had grown to 5,027 men, women and children, living in 821 new houses. The mill employees resided in the homes, paying low rental rates and enjoying free maintenance, low cost utilities, free garbage collection, and no taxes.

description: Electronic structure calculations combining the local-density approximation with an exact diagonalization of the Anderson impurity model show an intermediate 5f^5-5f^6-valence ground state and delocalization of the 5f^5 multiplet of the Pu atom 5f-shell in PuCoIn_5, PuCoGa_5, and δ-Pu. The 5f-local magnetic moment is compensated by a moment formed in the surrounding cloud of conduction electrons. For PuCoGa_5 and δ-Pu the compensation is complete and the Anderson impurity ground state is a singlet. For PuCoIn_5 the compensation is partial and the Pu ground state is magnetic. We suggest that the unconventional d-wave superconductivity is likely mediated by the 5f-states antiferromagnetic fluctuations in PuCoIn_5, and by valence fluctuations in PuCoGa_5.

description: The fractions and dimension of bars, rings and lenses are studied in the Near-IR S0 galaxy Survey (NIRS0S). We find evidence that multiple lenses in some barred S0s are related to bar resonances in a similar manner as the inner and outer rings, for which the outer/inner length ratio 2. Inner lenses in the non-barred galaxies normalized to galaxy diameter are clearly smaller than those in the barred systems. Interestingly, these small lenses in the non-barred galaxies have similar sizes as barlenses (lens-like structures embedded in a bar), and therefore might actually be barlenses in former barred galaxies, in which the outer, more elongated bar component, has been destroyed. We also find that fully developed inner lenses are on average a factor 1.3 larger than bars, whereas inner rings have similar sizes as bars. The fraction of inner lenses is found to be constant in all family classes (A, AB, B). Nuclear bars appear most frequently among the weakly barred (AB) galaxies, which is consistent with the theoretical models by Maciejewski & Athanassoula (2008). Similar sized bars as the nuclear bars were detected in seven 'non-barred' S0s. Galaxy luminosity does not uniquely define the sizes of bars or bar-related structures, neither is there any upper limit in galaxy luminosity for bar formation. Although all the family classes cover the same range of galaxy luminosity, the non-barred (A) galaxies are on average 0.6 mag brighter than the strongly barred (B) systems. Overall, our results are consistent with the idea that bars play an important role in the formation of the structure components of galaxies. The fact that multiple lenses are common in S0s, and that at least the inner lenses can have very old stellar populations, implies that the last destructive merger, or major gas accretion event, must have taken place at a fairly high redshift.

description: A nucleus on a meet-semilattice A is a closure operation that preserves binary meets. The nuclei form a semilattice N A that is isomorphic to the system NA of all nuclear ranges, ordered by dual inclusion. The nuclear ranges are those closure ranges which are total subalgebras (l-ideals). Nuclei have been studied intensively in the case of complete Heyting algebras. We extend, as far as possible, results on nuclei and their ranges to the non-complete setting of implicative semilattices (whose unary meet translations have adjoints). A central tool are so-called r-morphisms, that is, residuated semilattice homomorphisms, and their adjoints, the l-morphisms. Such morphisms transport nuclear ranges and preserve implicativity. Certain completeness properties are necessary and sufficient for the existence of a least nucleus above a prenucleus or of a greatest nucleus below a weak nucleus. As in pointfree topology, of great importance for structural investigations are three specific kinds of l-ideals, called basic open, boolean and basic closed. © 2022, The Author(s).

description: Inwiefern können JEs (an Hochschulen angesiedelte, strukturell unabhängige Studenteninitiativen, die Beratungsdienstleistungen anbieten) deutsche Hochschulen dabei unterstützen „neuen“ sozioökonomischen Anforderungen gerecht zu werden und beim Übergang in die erste Beschäftigung helfen? Innerhalb der Debatte um die Eigenschaften und Ziele der deutschen akademischen Ausbildung besteht ein weißer Fleck: Einer der tonangebenden Streitpunkte in jener Diskussion ist die Frage, inwiefern Studenten an Hochschulen arbeitsmarkt-relevante(s) Wissen und Kompetenzen erlangen. Momentan fehlt es jedoch an fundierten wissenschaftlichen Auseinandersetzungen, die sich intermediären Strukturen zwischen Universitäten und der Arbeitswelt widmen. Zur Erörterung dieses Problems werden bereits vorhandene JE-Publikationen, JE-Materialien und Experteninterviews mit Vertretern aus dem Hochschulwesen und der Privatwirtschaft herangezogen. Die Arbeit kommt zu dem Ergebnis, dass JEs zahlreiche persönliche und professionelle Lern-, Experimentier- und Erfahrungsmöglichkeiten beinhalten, die Studenten bereits während des Studiums mit auf den Weg gegeben werden können und die aus der Struktur und den internen Aktivitäten der Initiativen resultieren. JE können deutsche Hochschulen bzw. vereinzelte Individuen damit zumindest in puncto "traditionelle Schwächen des Hochschulstudiums" unterstützen. JEs scheinen ferner über die strukturellen Voraussetzungen für einfachere Berufsübergänge von Jungakademikern zu verfügen. Das vorliegende Potenzial wird jedoch offenbar kaum bzw. nicht genutzt. In puncto Übergang in die erste Beschäftigung können JEs Hochschulen damit momentan (noch?) nicht behilflich sein.

description: We use QCD sum rules to study the possible existence of a Θc(3250) charmed pentaquark. We consider the contributions of condensates up to dimension-10 and work at leading order in α_s. We obtain m(Θc) = (3.21 +/- 0.13) GeV, compatible with the mass of the structure seen by BaBar Collaboration in the decay channel B- -> p- Σc++ pi- pi-. The proposed state is compatible with a previous proposed pentaquark state in the anti-charmed sector.

description: A catalogue of simplicial hyperplane arrangements was first given by Grünbaum in 1971. These arrangements naturally generalize finite Coxeter arrangements and also the weak order through the poset of regions. The weak order is known to be a congruence normal lattice, and congruence normality of lattices of regions of simplicial arrangements can be determined using polyhedral cones called shards. In this article, we update Grünbaum’s catalogue by providing normals realizing all known simplicial arrangements with up to 37 lines and key invariants. Then we add structure to this catalogue by determining which arrangements always/sometimes/never lead to congruence normal lattices of regions. To this end, we use oriented matroids to recast shards as covectors to determine congruence normality of large hyperplane arrangements. We also show that lattices of regions coming from finite Weyl groupoids of any rank are always congruence normal. © 2021, The Author(s).

description: "The ACC/AHA Task Force on Practice Guidelines was formed to make recommendations regarding the diagnosis and treatment of patients with known or suspected cardiovascular disease (CVD). Coronary artery disease (CAD) is the leading cause of death in the United States. Unstable angina (UA) and the closely related condition of non–ST-segment elevation myocardial infarction (NSTEMI) are very common manifestations of this disease. The committee members reviewed and compiled published reports through a series of computerized literature searches of the English-language literature since 2002 and a final manual search of selected articles. Details of the specific searches conducted for particular sections are provided when appropriate. Detailed evidence tables were developed whenever necessary with the specific criteria outlined in the individual sections. The recommendations made were based primarily on these published data. The weight of the evidence was ranked highest (A) to lowest (C). The final recommendations for indications for a diagnostic procedure, a particular therapy, or an intervention in patients with UA/NSTEMI summarize both clinical evidence and expert opinion."

description: In the ultra-flexible factory, production machines reconfigure themselves ad-hoc depending on incoming production orders. Consequently, the IFF institute has developed a modular cyber-physical system (CPS) that consists of configurable robotic components. This paper is motivated by the need to reduce the effort and time associated with the CE conformity process for manufacturing systems with frequent reconfigurations, thus minimizing non-value adding machine downtime and increasing Overall Equipment Effectiveness (OEE). It presents an approach for an automated assistant system for the required risk assessment process using a database of previous CE conform system configurations and a reasoner that is able to verify the existence of a CE conform configuration that supersedes the hazards and risks of the new configuration. This allows the protective measures listed in the previous CE conform configuration to be reused, as well as a large part of the respective CE documentation.
Characterisation of the potential of frequency modulation and optical feedback locking for cavity-enhanced absorption spectroscopy

description: A combination of optical feedback self-locking of a continuous-wave distributed feedback diode laser to a V-shaped high finesse cavity, laser phase modulation at a frequency equal to the free spectral range of the V-cavity and detection of the transmitted laser beam at this high modulation frequency is described for possible application in cavity-enhanced absorption spectroscopy.In order to estimate an absorbance baseline noise of laser intensity and frequency modulated light triplet passed through the V-cavity in open air, a 1.5-cm long optical cell filled by C2H2 at low pressure was placed behind the cavity output mirror. The performance of the setup was evaluated from the experimental bandwidth normalised relative intensity noise on the cavity output and the frequency modulation absorption signals induced by C2H2 absorption in the 1.5-cm cell. From these data we estimate that the noise-equivalent absorption sensitivity of 2.1*10^-11 cm^-1 Hz^-1/2 by a factor of 11.7 above a shot-noise limit can be achieved for C2H2 absorption spectra extracted from the heterodyne beat signals recorded at the transmission maxima intensity peaks of the successive TEM00 resonances.

A new study of stellar substructures in the Fornax dwarf spheroidal galaxy

description: Using deep V, B-V wide-field photometry, we have conducted a new study of stellar over-densities in the Fornax dwarf spheroidal galaxy by determining detailed Star Formation Histories from Colour-Magnitude Diagram analysis. We have concentrated on the relatively young stellar component (<4 Gyr old), and compared this to the underlying Fornax field population. We have studied in more detail the previously known inner shell-like structure and shown that it has a well-defined age-metallicity relation with a peak at ~1.5 Gyr, [Fe/H]=-0.6 dex. Comparison to the Fornax centre shows that the over-dense feature is consistent with the age-metallicity relation of young field stars, and likely formed from Fornax gas. This is consistent with a scenario in which the over-density was formed by the re-accretion of previously expelled gas. We have also discovered a new stellar over-density, located 0.3 degrees (0.7 kpc) from the centre, which is only 100 Myr old, with solar metallicity. This feature constitutes some of the youngest, most metal-rich stars stars observed in Fornax to date. It is unclear how the young over-density was formed, although the age and metallicity of stars suggest this feature may represent the last star formation activity of the Fornax dSph.
