Working Girl Blues: The Life and Music of Hazel Dickens (2011)

Working Girl Blues: The Life and Music of Hazel Dickens. By Hazel Dickens and Bill C. Malone. (Urbana: University of Illinois Press, 2008. Pp. ix + 102, acknowledgements, biography, songs and memories, discography, index, illustrations. $ 17.95 paper.)Working Girl Blues is a fine book that documents the connection between a bluegrass musician's life and her songs. Hazel Dickens is a songwriter and bluegrass musician whose work has been widely performed and recorded. Bill C. Malone is a scholar and musician with important books to his credit: Country Music USA and Don't Get Above your RaisinCountry Music and the Southern Working Class.The text of Working Girl Blues is divided into two major sections. The first thirty pages are devoted to Hazel's biography, written by Bill C. Malone. In the biographical section, readers learn about her West Virginia family, their poverty, and search for better economic opportunities, Hazel's loves, and the struggles of a female bluegrass musician in a field dominated by good old boys. The final fifty-five or so pages contain the lyrics of Hazel's compositions, with Hazel's commentary about each song. She tells of the inspirations for the songs, her artistic struggles, and, in general, the experiences the songs reflect. The lock between the two sections is effective. In her section, Dickens refers to themes of her life that Malone touches on, but fills out the narrative with additional information. She tells it in a way that seems close to her speaking voice, and it makes the writing come to life.Many books about bluegrass assume that an artist's song selections or compositions somehow reflect the artist's attitude or experience, or that it somehow represents a shared community aesthetic. In Working Girl Blues, the connection between lived experience and composition is one of the main thrusts of the book. For example, Malone's biography tells that Hazel was a sickly child who, at about the age of three months, would not drink milk. The Mercer County, WV, doctor pronounced he'd done all he could do to treat Hazel's problem. Hazel's mother, Sarah, was a shy woman who rarely left her home place. However, despite her shyness, Sarah carried Hazel to the nearest big place to see a baby doctor. There she received the help that pulled Hazel through. Readers eventually learn how this episode in Hazel's early life inspired two of her songs: Mama's Hand and Carry Me Across the Mountain. Hazel comments on the special bond between herself and her mother, and the lyrics of these songs amply reinforce the point.Showing how new songs reflect life is important, because it demonstrates how a traditional songwriter combines a handed-down musical system with experience to create new work that fits a current scene. Working Girl Blues demonstrates that bluegrass is more than a collection of handed-down musical ideas that are assembled into pieces, but a vibrant musical form that artists shape to the circumstances of their lives.Working Girl Blues also addresses Appalachian migration for reasons relating to employment. …
Natural gas oxy-fuel cycles—Part 1: Conceptual aerodynamic design of turbo-machinery components (2009)

Several oxy-fuel cycles have been considered in the ENCAP project. These cycles require compressors and turbines that operate at different conditions and with different gas compositions from conventional heavy-duty gas turbines. Conceptual designs of selected turbo-machinery have therefore been carried out to assess the feasibility of the proposed components. A compressor and turbine from the SCOC-CC and S-Graz cycles have been selected for this preliminary design study. The unusual boundary conditions would ideally require new hardware. As entirely new designs might rule out the commercial realization of these cycles possible ways of using existing components for the SCOC-CC compressor have been investigated.
<title>Flexible, runtime-efficient vector-radix algorithms for multidimensional fast Fourier transform</title> (1994)

Dynamic development in digital signal processing is inseparably bound to the disclosure of the fast Fourier transform (FFT). Implications from the application of these efficient algorithms for calculating the discrete (inverse) Fourier transform are significant in many ways. Applicability of FFT algorithms ranges far into almost every aspect of physics and performs a central role in analysis, design and implementation of DSP algorithms and digital systems. Consumed computer time almost ceases to be a problem when using FFT compared with straightforward discrete Fourier transform (DFT). The cutdown on consumed computer time by usage of FFT algorithms even holds greater promise for multidimensional applications with in general more complex tasks and heavier data loads to cope with. Without multidimensional FFT algorithms for high speed convolution or spectral analysis the successes for example in SAR, tomography, data compression or picture processing could not have been achieved. Since the introduction of the Cooley-Tukey-algorithm in 1965 methods to calculate the two- or N dimensional Fourier transform of a set of data are based essentially on the separability of the 2D FFT. With a 1D FFT algorithm the data set is `combed' row- and columnwise to form the 2D transform of the calculated 1D transforms. After some basics and recalling some different conventional approaches to 1D and 2D Fourier transform the paper concentrates on Vector-Radix-algorithms which decimate and transform a 2D data set simultaneous for both index directions and therefore seem suitable for parallelization. Vector-Radix-approaches are derived for general radices and for the 2D case also for nonquadratic data sets.

Immunogenicity of bacterial carbohydrates: cholera toxin modulates the immune response against dextran B512 (1997)

Native dextran B512 is a T-cell-independent (TI) antigen. By conjugating low molecular weight (MW) dextran to protein, a T-cell-dependent (TD) response against dextran can be obtained. We have previously reported the effects of native dextran and two different protein-dextran conjugates on the immune system. While one type of conjugate induced an optimal TD response, the other conjugate ('suboptimal') evoked a response more similar to that induced by native dextran, i.e. with little immunoglobulin class switch and with a secondary response of similar magnitude to the primary response. In order to investigate if it was possible to augment the anti-dextran response we examined the effects of cholera toxin (CT) in our dextran model system. CT is a potent mucosal, as well as systemic, adjuvant with effects on T cells, B cells and antigen-presenting cells. We show that CT is a very efficient adjuvant for both the TD and TI forms of dextran. A major increase in IgM and IgG anti-dextran antibody production was detected after administration of CT together with the conjugates compared with a conventional alum adjuvant. The effect was most pronounced for the suboptimal TD conjugate. CT was also able partially to abrogate the unresponsiveness to dextran in the TI type 2 (TI-2) non-responder strain CBA/N. CT was also found to be a very potent adjuvant for native dextran, secondary IgM levels were enhanced eightfold by the co-administration of CT. Furthermore CTB-Dx, which is a conjugate of the non-toxic part of CT and low MW, non-immunogenic dextran, elicited an anti-dextran response in nude mice. Collectively, our data show that it is possible to improve the immunogenicity of both TD and TI forms of a carbohydrate by co-administration of CT. This is indicative of two components of the adjuvant effect, one could enhance antigen presentation and costimulation of T cells and the other could have a direct stimulatory effect on B cells.
Structural phase transition in CuFe2O4 spinel (2013)

A structural transition with a reduction in symmetry of the high temperature cubic phase (sp. gr. Fd3m) to the tetragonal phase (sp. gr. I41/amd) and the appearance of a ferrimagnetic structure occur in CuFe2O4 copper ferrite at T ≈ 440°C. It is established by an experiment on a high-resolution neutron diffractometer that the temperature at which long-range magnetic order occurs is higher than that of tetragonal phase formation. When cooling CuFe2O4 spinel from 500°C, the equilibrium coexistence of both phases is observed in a fairly wide temperature range (∼40°C). The composition studied is a completely inverse spinel in the cubic phase, and in the tetragonal phase the inversion parameter does not exceed few percent (x = 0.06 ± 0.04). At the same time, the phase formed upon cooling has a classical value of tetragonal distortion (γ ≈ 1.06). The character of temperature changes in the structural parameters during the transition from cubic to tetragonal phase indicates that this transition is based on the Jahn-Teller distortion of (Cu,Fe)O6 octahedra rather than the mutual migration of copper and iron atoms.
Sensor-based diagnosis of dynamical systems (1995)

Analysis of nitrite, the indicator of nitric oxide (NO) generation in vivo, provides a useful tool to study NO synthesis in vivo. A fast and sensitive fluorometric CE method was developed for determination of nitrite in human plasma through its derivatization with 2,3-diaminonaphthalene (DAN). Nitrite in human plasma was easily reacted with DAN under acid conditions to yield the highly fluorescent 2,3-naphthotriazole (NAT). Fluorescence detection was optimized to achieve subnanomolar detection which allows a direct analysis of plasma samples unlike most CE-UV methods using sample stacking. Acetonitrile was used to remove the protein. Short-end injection and a high voltage (-30 kV) were used to shorten the analysis time. The good separation was achieved with 20 mM borate buffer at pH 9.23. The separation of NAT was obtained within 1.4 min. The deproteinized plasma sample was injected hydrodynamically for 5s at -50 mbar into a 60 cm × 75 μm internal diameter uncoated fused-silica capillary. Excitation wavelength was selected with a broad-band filter (240-400 nm), and the emitted light was measured at 418 nm by the use of a cutoff filter. A good linearity (R(2)=0.9975) was obtained in the range from 2 to 500 nM. The detection limit of nitrite was 0.6 nM in original plasma samples, which is 750 times lower than our previous CE-UV method. The developed fluorometric CE method offers the advantages of more simple system and lower cost compared with the current fluorometric HPLC methods without losing sensitivity. The detected mean nitrite concentration in human plasma by this method was consistent with the most frequently reported values.
Looking for new, not known music only (2004)

With the growth of digital music, content-based music retrieval (CBMR) has attracted increasingly attention. For most CBMR systems, the task is to return music objects similar to query in syntactic properties such as pitch and interval contour sequence. These approaches provide users the capability to look for music that has been heard. However, sometimes, listeners are looking, not for music they have been known, but for music that is new to them. Moreover, people sometimes want to retrieve music that "feels like" another music object or a music style. To the best of our knowledge, no published work investigates the content-based music style retrieval. This paper describes an approach for CBMR by melody style. We proposed four types of query specification for melody style query. The output of the melody style query is a music list ranked by the degree of relevance, in terms of music style, to the query. We developed the melody style mining algorithm to obtain the melody style classification rules. The style ranking is determined by the style classification rules. The experiment showed the proposed approach provides a satisfactory way for query by melody style.
The Place of Man in International Society (2001)

The human rights theme which came back at the end of the seventies, was used by the West in the eighties, to help the communist fall. Although in progress, the universal value of these rights is still challenged especially by the southern countries. However, the fall of the Berlin wall has allowed to reunite civil and political rights with social and economic rights in a common approach. The notion of human rights spread in the nineties, incorporating new subjects such as environmental protection. Under the influence of new actors, it was also brought to groups or communities. The rising in power of human rights goes with a growth of judicial control which best guarantees their respect. However, in the lack of an institution or a global legal structure in charge of checking on it, the latter remains limited.
Antioxidant Activity of Diethyldithiocarbamate (1996)

Diethyldithiocarbamate (DDC), a potent copper chelating agent, has long been used for the treatment of oxygen toxicity to the central nervous system, as an immunomodulator to treat cancer, and in HIV-infected patients. We evaluated the antioxidant properties of DDC, including its scavenging of reactive oxygen species, its reducing properties, its iron-chelating properties, and its protective effects on oxidant-induced damage to brain tissue, protein, human LDL, and DNA. It is found that DDC is a powerful reductant and antioxidant since it scavenges hypochlorous acid, hydroxyl radical and peroxynitrite; it chelates, then oxidizes ferrous ions; it blocks the generation of hydroxyl radicals and inhibits oxidative damage to deoxyribose, protein, DNA, and human LDL. These findings may provide an explanation for the apparent beneficial effects of DDC against oxidative stress-related diseases that have been observed in experimental and clinical studies.
Color (2018)

Although colors are central to our cultural and social interactions with the world, color is a topic that has more often been pushed to the periphery of anthropological study. This entry outlines an anthropology of colors by tracing approaches to color, from interests in perception, linguistics, color naming, evolutionary theories, and semiotics through to the more recent resurgence in material culture studies and the sensorial turn in anthropology since the 1990s. Works since the mid‐2000s have attempted to overcome prior challenges posed by considering color as a fixed single hue by instead examining what colors do through their transformation and their relations with other colors, properties, things, and people. This focus has opened up new possibilities—for example, considering how indigenous peoples have resocialized their worlds by using colors in novel ways following experiences of colonialism. A renewed interest in light and the increasing experience of colors as mediated through digital screens indicate future directions for anthropological investigations of colors.
Alkali Metal-Promoted La<sub><i>x</i></sub>Sr<sub>2–<i>x</i></sub>FeO<sub>4−δ</sub> Redox Catalysts for Chemical Looping Oxidative Dehydrogenation of Ethane (2018)

Chemical looping oxidative dehydrogenation (CL-ODH) represents a redox approach to convert ethane into ethylene under an autothermal scheme. Instead of using gaseous oxygen, CL-ODH utilizes lattice oxygen in transition metal oxides, which acts as an oxygen carrier or redox catalyst, to facilitate the ODH reaction. The oxygen-deprived redox catalyst is subsequently regenerated with air and releases heat. The current study investigated alkali metal (Li, Na, and/or K)-promoted LaxSr2–xFeO4−δ (LaSrFe) as redox catalysts for CL-ODH of ethane. While unpromoted LaSrFe exhibited poor ethylene selectivity, addition of Na or K promoter achieved up to 61% ethane conversion and 68% ethylene selectivity at 700 °C. The promotional effect of K on LaSrFe was characterized using X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), low-energy ion scattering spectroscopy (LEIS), transmission electron microscopy (TEM), O2-temperature-programmed desorption (TPD), H2-temperature-programmed reduction (TPR), and 18O2 surface exchange. XPS and XRD showed that K incorporates into the mixed-oxide structure at low loading levels (e.g., 0.1K-LaSrFe), whereas the surface of LaSrFe was enriched with K cation at high loading levels. LEIS indicates that the outermost surface layer was covered by potassium oxide. This surface layer was characterized to be amorphous under TEM. It was further determined that the surface layer increased the resistance for O2– diffusion from the bulk and its subsequent evolution into electrophilic oxygen species on the surface. As such, nonselective oxidation of ethane is inhibited. The synergistic effect of copromoting LaSrFe with Li and K was also investigated. Li and K copromotion improved the redox catalyst performance to 86% ethylene selectivity and 60% ethane conversion while maintaining an oxygen capacity of ca. 0.65 wt %, making it a promising candidate for CL-ODH.
Lunar Core and Mantle. What Does LLR See (2008)

Vitamin D and the vitamin D receptor (VDR) complex have been reported to inhibit the growth of several types of tumor; however, their function in papillary thyroid cancer (PCT) remains unknown. In addition, the Wnt/β‑catenin signaling pathway was discovered to serve a critical role in the pathology of PCT. Therefore, the present study aimed to determine the role of the VDR and its association with Wnt/β‑catenin signaling in vitamin D‑treated PTC cells. VDR expression was detected in human PTC cells (including MDA‑T120, MDA‑T85, SNU‑790 and IHH4 cells) and thyroid follicular cells (Nthy‑ori 3‑1 cells). SNU‑790 and IHH4 cells were infected with KD‑VDR or negative control (KD‑NC) lentiviruses, treated with 1,25(OH)2D3 (the active form of vitamin D), and subsequently referred to as the KD‑VDR&vitD and KD‑NC&vitD groups, respectively. Additionally, PTC cells infected with KD‑NC and not treated with 1,25(OH)2D3 were used as the normal control and referred to as the KD‑NC group. VDR mRNA and protein expression levels were increased in MDA‑T120, SNU‑790 and MDA‑T85 cells compared to Nthy‑ori 3‑1 cells, whereas in IHH4 cells, VDR mRNA and protein expression levels were similar to Nthy‑ori 3‑1 cells. In SNU‑790 and IHH4 cells, cell proliferation and invasion were decreased in the KD‑NC&vitD group compared with the KD‑NC group, but increased in the KD‑VDR&vitD group compared with the KD‑NC&vitD group. Cell apoptosis was increased in the KD‑NC&vitD group compared with the KD‑NC group, and decreased in the KD‑VDR&vitD group compared with the KD‑NC&vitD group. Furthermore, the expression levels of Wnt family member 3 and catenin β1 were decreased in the KD‑NC&vitD group compared with the KD‑NC group, but increased in the KD‑VDR&vitD group compared with the KD‑NC&vitD group. In conclusion, the present study revealed that VDR‑KD attenuated the antiproliferative, pro‑apoptotic and anti‑invasive effects of vitamin D in PTC by activating the Wnt/β‑catenin signaling pathway.
DevOps for Better Software Security in the Cloud Invited Paper (2017)

The DevOps paradigm means that development and operations for an organisation blend together. For security, this implies that information on detected attacks can be fed back to the development, enabling faster eradication of vulnerabilities in software. This is particularly important in cloud installations, where release cycles can be less than a day. This paper argues that DevOps can be employed for overall improved software security.
A survey of unit testing practices (2006)

Unit testing is testing of individual units or groups of related units. What are a company's typical strengths and weaknesses when applying unit testing? Per Beremark and the author surveyed unit testing practices on the basis of focus group discussions in software process improvement network (SPIN) and launched a questionnaire to validate the results. This survey is an indication of unit testing in several companies. You can use the questionnaire at your own company to clarify what you mean by unit testing, to identify the strengths and weaknesses of your unit testing practices, and to compare with other organizations to improve those practices
Photocrosslinked poly(ester‐anhydride) microspheres with macroporous structure (2013)

In this work, the new method of preparation biodegradable microspheres with macroporous structure is presented. Typical methods used for generation of porous structures in microspheres obtained from preformed polymers require the use of additional substances acting as porogens. In this study, the porosity was achieved as the effect of photocrosslinking, without porogens. Microspheres were prepared using emulsion solvent evaporation technique from functional poly(ester‐anhydride)s with different amount of allyl groups in the side chains. The crosslinking was carried out by UV irradiation during the solvent evaporation (photoinitiator was introduced to polymer solution). The size of microspheres obtained was in the range of 1.7 – 4 µm (small microspheres) or 31 – 50 µm (large ones) and depended on the conditions used in emulsion formulation process. Effectiveness of the crosslinking was characterized by the content of insoluble part of samples, and it was in the range of 42–89%. The content of insoluble part of sample of microspheres and their porosity were dependent on functionality of poly(ester‐anhydride)s, the amount of photoinitiator used, and also on size of microparticles. The small particles were always more crosslinked than the large ones, but the latter were more porous than the small ones. Crosslinked microparticles indicated higher loading efficiency of model compound and appeared to degrade faster than uncrosslinked ones, probably due to their high porosity. The high porosity of microspheres obtained would enable their eventual use in pulmonary drug delivery systems or in construction of porous scaffolds for tissue engineering.

Immunomodulatory effects of probiotics. (2009)

Probiotics have been mostly examined in the prevention and treatment of gastrointestinal disorders. The mechanisms are not fully understood, but they are likely to be mediated by the gut mucosal immune system. The immunomodulatory effects of specific probiotic strains have not been systematically investigated from in vitro screenings to short-term clinical trials and longer interventions evaluating the clinical outcome of the probiotic intervention. Although probiotics have reduced the incidence or duration respiratory infections in healthy children and adults, not much is known about their actual immunomodulatory effects in healthy adults. The immunomodulatory effects of probiotics were systematically investigated in a primary cell culture model using human peripheral blood mononuclear cells (PBMC), as well as in healthy adults in randomised, double-blind, placebo-controlled clinical intervention studies. It was found that probiotics have strain-specific effects on immune system in healthy adults and especially L. rhamnosus GG (LGG®) seemed to posses anti-inflammatory potential reflected as small decrease in inflammatory mediators, such as sensitive CRR as well as in the modulation of global serum lipidomics profiles. The mechanisms of specific host-probiotic interactions in the gut resulting in systemic and clinical effects warrants further investigations.
