Ignition and extinction fronts in counterflowing premixed reactive gases
Full text linkWe describe two-dimensional steady propagating flame fronts in the stagnation mixing layer between two opposed streams of the same reactive mixture, the propagation taking place in the direction perpendicular to the plane of strain. The front, which is curved by the nonuniform flow field, separates a chemically frozen region from a region with a twin-flame configuration. The front velocity is calculated in terms of the Lewis number, Le(F), and the Damkohler number, Da. Da, equal to the inverse of the Karlovitz number, is defined as the ratio of the strain time to the transit time through the planar unstrained flame. For the cases corresponding to large Da, difficult to tackle numerically, analytical expressions are given, characterizing the flame shape, and the variation of the burning rate along the flame front from the nose up to the planar trailing branches. For moderately large and low values of Da, the study is carried out numerically, yielding, in particular, the propagation velocity in terms of Da, for different values of Le(F). Different combustion regimes are thus described including flames propagating toward the unburnt mixture, or ignition fronts, standing flames and retreating flames, or extinction fronts. We also describe stationary cylindrical flames of finite-extent, or 2D burning spots. In particular, a critical Lewis number is found, below which negative propagation speeds do not exist while the 2D burning spots mentioned may be encountered. Typically, these exist only for sufficiently small Le(F) if the Da is within a range [Da(min), Da(max)], depending on Le(F). For Da < Da(min), the 2D spots are quenched, whereas as Da is increased, they grow in size, tending to give birth to propagating (ignition) fronts; Da(max) is indeed found to be the smallest Da allowing for ignition fronts. We notice that the range of existence of the 2D spots, for a given Le(F), can overlap with that of retreating (extinction) fronts, and possibly with that of 3D spots, or flame balls, in this flow. However, the 3D case is not addressed in this work

Evaluation of faba bean breeding lines under different rainfed conditions
No full textDrought is one of the major factors limiting faba bean (Vicia faba L.) production in Mediterranean region with irregular water distribution and moisture level below than 500 mm. A major objective of any breeding program in this region is to develop drought-tolerant/resistant genotypes of faba bean that are well adapted to a wide range of environments, since environmental variation causes differential genotypic responses. The objective of this study was to evaluate the response of eight faba bean drought tolerant breeding lines - selected in Tel Hadya (Syria) with moisture level below 300 mm - and three cultivars under rainfed conditions in two stations (Terbol and Kfardan) of the International Center for Agricultural Research in the Dry Areas (ICARDA) representing two different agro-climatic zones in Bekaa, Lebanon during 2008/2009 cropping season. The breeding lines were compared in terms of growth vigor, yield, yield components, harvest index and water use efficiency in both locations. The seasonal accumulated rainfall in Kfardan station (289 mm) was 42% less than that recorded in Terbol station (501 mm). Genotypic variations for several yield characters were recorded in both locations. Plant height, number of nods per plant, number of lateral branches and internodes’ length were higher in Terbol by 14%, 50%, 25% and 48%, respectively, than those recorded in Kfardan. Highest grain yields were recorded in Terbol station by the genotypes ILB1814 (Syrian local large) and ILB1266 (Aguadolce), followed by DT/B7 9013, ILB 1270 Reina Blanca and DT/B7 9005. Similarly in Kfardan, the genotype DT/B7 9013 had the highest grain yield, followed by ILB 1814 (Syrian local large), DT/B7 9005, DT/B7 9043 and ILB 1266 (Aguadolce). The biological yield, total biomass, grain yield, harvest index, number of pods per plant and the number of seeds per plant recorded in Terbol were higher by 39%, 16%, 77%, 30%, 54%, and 53%, respectively, than those recorded in Kfardan. This means lines yielding good under low rainfall area may not perform well under high rainfall environments. The biomass water use efficiency (WUEb) ranged from 0.4 to 0.61 kg m-3 in Terbol and from 0.63 to 0.89 kg m-3 in Kfardan, whereas the grain water use efficiency (WUEg) ranged from 0.32 to 0.61 kg m-3 in Terbol and from 0.36 to 0.55 kg m-3 in Kfardan. The WUEb was significantly higher (by 50%) in kfardan than in Terbol whereas the WUEg in Kfardan was significantly lower (by 8%) than that in Terbol. Thus it seems that the remobilization of assimilates is limited in Kfardan due to the severe terminal drought

A Tripartite Post-Recession Rebalancing
No full textIn this latest Advance & Rutgers Report, entitled “A Tripartite Post-Recession Rebalancing,” Dean James W. Hughes and Professor Joseph J. Seneca deliver an incisive assessment of the current market conditions and obstacles in the path of our economic recovery. They offer a statistical cautionary tale that the private and public sector need to hear and acknowledge in order for the economy to make continued progress.This report was published as Issue Paper Number 7, November 2011, in Advance & Rutgers Report
Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
Full text linkFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
Full text linkAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
