    REMOVAL OF ACID-SOLUBLE LIGNIN FROM BIOMASS EXTRACTS USING AMBERLITE XAD-4 RESIN

    Get PDF
    This paper describes a method for the removal of acid-soluble lignin from acid hydrolyzed hemicelluloses extracted from a mixture of northern hardwood chips, by using Amberlite XAD-4 resin, which was shown to remove 100% of furan derivatives and 90% of acid-soluble lignin. Subsequent fermentation of the resin treated hydrolyzates gave ethanol yields as high as 97% of theoretical and showed a marked increase in fermentation rate. Regeneration of resin performed with 75% acetone was 85% efficient with respect to acid soluble lignin

    Extremely Luminous Far-infrared Sources (ELFS)

    Get PDF
    The Infrared Astronomical Satellite (IRAS) survey uncovered a class of Extremely Luminous Far Infrared Sources (ELFS), exhibiting luminosities up to and occasionally exceeding 10 to the 12th power L sub 0. Arguments are presented to show that sources with luminosities L equal to or greater than 3 x 10 to the 10th power L sub 0 may represent gas rich galaxies in collision. The more conventional explanation of these sources as sites of extremely active star formation fails to explain the observed low optical luminosities of ELFS as well as their high infrared excess. In contrast, a collisional model heats gas to a temperature of approx. 10 to the 6th power K where cooling takes place in the extreme ultraviolet. The UV is absorbed by dust and converted into far infrared radiation (FIR) without generation of appreciable optical luminosity. Gas recombination as it cools generates a Lyman alpha photon only once for every two extreme ultraviolet approx. 50eV photons emitted by the 10 to the 6th power gas. That accounts for the high infrared excess. Finally, the model also is able to explain the observed luminosity distribution of ELFS as well as many other traits

    Two-Tier Compensation Structures: Their Impact on Unions, Employers, and Employees

    Get PDF
    Martin conducted a study at a large company where its various wage tier systems allowed assessment of the long-term impact of tiers. Part of this study included the development of a survey designed to explore eight research questions related to tiers and to test five hypotheses of low-tier v. high-tier employees.https://research.upjohn.org/up_press/1102/thumbnail.jp

    Nucleon-Nucleon Scattering in a Harmonic Potential

    Full text link
    The discrete energy-eigenvalues of two nucleons interacting with a finite-range nuclear force and confined to a harmonic potential are used to numerically reconstruct the free-space scattering phase shifts. The extracted phase shifts are compared to those obtained from the exact continuum scattering solution and agree within the uncertainties of the calculations. Our results suggest that it might be possible to determine the amplitudes for the scattering of complex systems, such as n-d, n-t or n-alpha, from the energy-eigenvalues confined to finite volumes using ab-initio bound-state techniques.Comment: 19 pages, 13 figure

    Recent advances in emerging integrated anticorrosion and antifouling nanomaterial-based coating solutions

    Get PDF
    The rapid progress in the marine industry has resulted in notable challenges related to biofouling and surface corrosion on underwater infrastructure. Conventional coating techniques prioritise individual protective properties, such as offering either antifouling or anticorrosion protection. Current progress and innovations in nanomaterials and technologies have presented novel prospects and possibilities in the domain of integrated multifunctional coatings. These coatings can provide simultaneous protection against fouling and corrosion. This review study focuses on the potential applications of various nanomaterials, such as carbon-based nanostructures, nano-metal oxides, polymers, metal–organic frameworks, and nanoclays, in developing integrated multifunctional nano-based coatings. These emerging integrated multifunctional coating technologies recently developed and are currently in the first phases of development. The potential opportunities and challenges of incorporating nanomaterial-based composites into multifunctional coatings and their future prospects are discussed. This review aims to improve the reader’s understanding of the integrated multifunctional nano-material composite coating design and encourage valuable contributions to its development.publishedVersio

    The Burden of Acting White: Implications for Transition

    Get PDF
    This study used a phenomenological qualitative approach that engaged Black students in discussions about the burden of acting White and its impact on their in-school and postschool outcomes and postschool transition visions. Six seventh- and eighth-grade Black students identified as at risk for school failure, a principal, and five teachers participated in this study. The authors identified and addressed the following themes: (a) the existence of the burden of acting White; (b) students' definitions of acting Black or White; (c) teachers' inability to intervene and counteract the impacts of acting White; (d) the significance of postschool visions; and (e) academic orientation. The authors conclude by discussing the need for transition programs focused on self-determination.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

    Advancing knowledge in stepped-wedge cluster randomised controlled trials

    Get PDF
    This thesis aims to extend the existing knowledge and enhance the methodological quality of future stepped-wedge cluster randomised trial (SW-CRTs). A systematic review of published SW-CRTs shows that pre-trial sample sizes calculations display a poor standard of reporting, with little adherence to published guidelines. The methodological rigor is often substandard, with inappropriate methods often used to determine sample size. In SW-CRTs, it is assumed that the correlation between observations is independent of the timing of them. We test the validity of this assumption by outlining a method to estimate the within-period and inter-period correlation. A case study illustrates what these correlations may look like in practice. The impact of varying cluster size in a SW-CRT is then demonstrated by comparing a design with unequal cluster size to a design with equal cluster size. A simulation study provides evidence that the SW-CRT is affected less, on average, than a P-CRT by varying cluster size. However, the potential power in a SW-CRT with unequal cluster sizes is extremely variable. A practical method for estimated power in a SW-CRT with varying cluster size is then illustrated through a Stata function
