Adsorption of Carbon Dioxide from Gas Streams via Mesoporous Spherical-Silica Particles (2010)

A relatively new mesoporous silica sorbent for environmental protection applications (i.e., mesoporous spherical-silica particles [MSPs]), was modified by N-[3-(trimethoxysilyl)propyl]ethylenediamine (EDA) solution and was tested for its potential in the separation of carbon dioxide (CO2) from flue gas. The CO2 adsorption capacity of MSP and MSP (EDA) increased with temperature from 20 to 60 degrees C but decreased with temperature from 60 to 100 degrees C. The mechanism of CO2 adsorption on both samples is mainly attributed to physical interaction regardless of temperature change. The MSP (EDA) have good adsorption performance as compared with EDA-modified zeolite or granular activated carbon conducted in this study and many types of silica sorbents reported in the literature. The cyclic CO2 adsorption showed that spent MSP (EDA) could be effectively regenerated at 120 degrees C for 25 min and CO2 adsorption capacity of MSP (EDA) was preserved during 16 cycles of adsorption and thermal regeneration. These results suggests that MSP (EDA) are efficient CO2 sorbents and can be stably used in the prolonged cyclic operation.

Mnt, a novel Max-interacting protein is coexpressed with Myc in proliferating cells and mediates repression at Myc binding sites. (1997)

The small constitutively expressed bHLHZip protein Max is known to form sequence-specific DNA binding heterodimers with members of both the Myc and Mad families of bHLHZip proteins. Myc:Max complexes activate transcription, promote proliferation, and block terminal differentiation. In contrast, Mad:Max heterodimers act as transcriptional repressors, have an antiproliferative effect, and are induced upon differentiation in a wide variety of cell types. We have identified a novel bHLHZip Max-binding protein, Mnt, which belongs to neither the Myc nor the Mad families and which is coexpressed with Myc in a number of proliferating cell types. Mnt:Max heterodimers act as transcriptional repressors and efficiently suppress Myc-dependent activation from a promoter containing proximal CACGTG sites. Transcription repression by Mnt maps to a 13-amino-acid amino-terminal region related to the Sin3 interaction domain (SID) of Mad proteins. We show that this region of Mnt mediates interaction with mSin3 corepressor proteins and that its deletion converts Mnt from a repressor to an activator. Furthermore, wild-type Mnt suppresses Myc+Ras cotransformation of primary cells, whereas Mnt containing a SID deletion cooperates with Ras in the absence of Myc to transform cells. This suggests that Mnt and Myc regulate an overlapping set of target genes in vivo. When mnt is expressed as a transgene under control of the beta-actin promoter in mice the transgenic embryos exhibit a delay in development and die during mid-gestation, when c- and N-Myc functions are critical. We propose that Mnt:Max:Sin3 complexes normally function to restrict Myc:Max activities associated with cell proliferation.
Industrial Robotics (1988)

A text book providing a thorough introduction to the design and application of industrial robotics. The book is in three sections, the first 'An Overview' contains the introduction, a tongue in cheek 'Origin of the Robot Species', and 15 page chapter on classification and description of industrial robots. The section - Robot Design and Control-is nearly 190 pages long and is divided into nine chapters. Each chapter is dedicated to a particular aspect of robot design or control including subjects such as transmission systems and power drives, which other books ignore or allocate only a few lines at the most.
Management of Wild Pigs (2019)

This chapter discusses tools and methodologies currently available to manage wild pig populations and wild pig damage in North America, particularly on tools and methodologies supported by scientific data. It explores strategic application of available tools and methodologies and describes specific case studies from successful wild pig control programs. The success of any wildlife management program depends upon development of a sound plan, and management programs for wild pigs are no different. Sound plans include careful design and well-defined goals and benchmarks. Use of traps to capture wild pigs in North America predates damage management efforts. Domesticated pigs in North America historically were free roaming and subsequently captured for food and to mark for ownership in the fall through trapping. Gate dimensions are an important consideration for most trappers. Smaller gates weigh and cost less, but are potentially less effective than larger/wider gates.
Perspective high-temperature ceramic composite materials (2011)

The high-temperature glass-matrix and ceramic-matrix composites developed by the RIAM are overviewed. The distinctive properties of the developed composites are their high stability at temperatures above 1200°C in an oxidizing medium, high endurance and corrosion resistance, and low density and thermal expansion. Therefore, these composites are unique for production of heat-loaded units and parts of advanced engines. A characteristic feature of the SiC/SiC ceramic-matrix composite is its high resistance (by contrast to traditional monolithic ceramics) to thermocyclic loadings in the medium of fuel combustion products, which is due to its regulated and manageable structure.
Female segregation patterns of the putative Y‐chromosome‐specific microsatellite markers INRA124 and INRA126 do not support their use for cattle population studies (2009)

Here we tested the segregation and paternal compatibility of markers INRA124 and INRA126 on female DNA in 10 different cattle families, in order to clarify the usefulness of these microsatellites for the study of male-mediated population processes in cattle. Their performance was compared with that of four microsatellites located in the PAR-BTAY (UMN0108, UMN0803, UMN0929 and UMN0905) and another one male-specific microsatellite (INRA189). INRA124 and INRA126 amplified the same sized fragment in both sexes. Same size alleles were sequenced and the high homology found allowed us to rule out non-specific female amplification. INRA124 showed full parental compatibility, whilst the locus INRA126 showed 55% parental incompatibility. Based on these observations, it is recommended that markers INRA124 and INRA126 should not be used in studies to characterize male-mediated genetic events in cattle.
Human sex reversal is caused by duplication or deletion of core enhancers upstream of SOX9 (2019)

Initial steps in the sex determination of the (human) testis depend on SRY regulating SOX9, but the exact mechanism that controls SOX9 expression remains unknown. These authors discovered four overlapping copy number variations (CNVs) upstream of SOX9 as the causes of sex reversal in two 46,XX DSD (with duplications) and two 46,XY DSD patients (with deletions). Prompted by this, they performed studies of these CNVs in cell systems and in mice, and found three essential regulatory elements for normal testis and male sex development, namely eSR-A, eSR-B and eALDI.
Quartzite rheology under geological conditions (1990)

Abstract The problems associated with extrapolating laboratory measurements on quartzite rheology to geological conditions are discussed, with special reference to the question of equilibration with respect to the effect of water. Some new results on synthetic specimens crystallized from wet amorphous silica are presented in the expectation that water equilibration is more closely attained in these than in natural quartz specimens. These results and earlier ones from the literature are collated and used to arrive at limits on quartzite flow strength under geological conditions.

Investigating the Effects of Tissue-Specific Extracellular Matrix on the Adipogenic and Osteogenic Differentiation of Human Adipose-Derived Stromal Cells Within Composite Hydrogel Scaffolds (2019)

While it has been postulated that tissue-specific bioscaffolds derived from the extracellular matrix (ECM) can direct stem cell differentiation, systematic comparisons of multiple ECM sources are needed to more fully assess the benefits of incorporating tissue-specific ECM in stem cell culture and delivery platforms. To probe the effects of ECM sourced from decellularized adipose tissue (DAT) or decellularized trabecular bone (DTB) on the adipogenic and osteogenic differentiation of human adipose-derived stem/stromal cells (ASCs), a novel detergent-free decellularization protocol was developed for bovine trabecular bone that complemented our established detergent-free decellularization protocol for human adipose tissue and did not require specialized equipment or prolonged incubation times. Immunohistochemical and biochemical characterization revealed enhanced sulphated glycosaminoglycan content in the DTB, while the DAT contained higher levels of collagen IV, collagen VI and laminin. To generate platforms with similar structural and biomechanical properties to enable assessment of the compositional effects of the ECM on ASC differentiation, micronized DAT and DTB were encapsulated with human ASCs within methacrylated chondroitin sulfate (MCS) hydrogels through UV-initiated crosslinking. High ASC viability (>90%) was observed over 14 days in culture. Adipogenic differentiation was enhanced in the MCS+DAT composites relative to the MCS+DTB composites and MCS controls after 14 days of culture in adipogenic medium. Osteogenic differentiation studies revealed a peak in alkaline phosphatase (ALP) enzyme activity at 7 days in the MCS+DTB group cultured in osteogenic medium, suggesting that the DTB had bioactive effects on osteogenic protein expression. Overall, the current study suggests that tissue-specific ECM sourced from DAT or DTB can act synergistically with soluble differentiation factors to enhance the lineage-specific differentiation of human ASCs within 3-D hydrogel systems.

Integrated Genomic and Proteomic Analysis of Signaling Pathways in Dendritic Cell Differentiation and Maturation (2002)

Dendritic cells (DCs) are antigen-presenting cells that play a major role in initiating primary immune responses. Their phenotypic and functional characteristics are intimately linked to their stage of maturation. The specific biochemical pathways and genes whose expression mediates differentiation of progenitors to DCs and their maturation are largely undefined. We recently utilized two approaches, DNA microarrays and proteomics, to analyze the expression profile of human CD14(+) blood monocytes and their derived DCs. Approximately 4% of the genes or proteins expressed were found to be regulated during DC differentiation. Most of these genes were not previously associated with DCs and included genes highly relevant to DC functions (genes involved in antigen presentation, cell adhesion and motility, lipid metabolism). Genes involved in specific signaling pathways, including IkappaBalpha, PPAR-gamma and C/EBPalpha as well as two members of the family of transcription factors, interferon regulatory factors (IRFs), were also modified. Modulation of IRF gene expression is of particular interest because of their functional roles in innate and adaptive immune responses. IRF-family members control the expression of proteins that include type-1 interferons, interleukin-12, interleukin-15, MHC molecules and adhesion molecules. They have also been found to play an important role in lymphocyte development. In contrast to DC differentiation, very few genes were modified at the transcript level during DC maturation as determined by microarray experiments. Further analysis suggested that DC maturation is largely controlled by posttranscriptional and posttranslational modifications. The use of proteomics is therefore necessary for a full comprehension of DC maturation process.
Ultra-Low Voltage Time-Resolved Emission Measurements from 32 nm SOI CMOS Integrated Circuits (2014)

Abstract This work presents a comparison of two generations of Superconducting nanowire Single-Photon Detector (SnSPD) prototypes used for Time-Resolved Emission (TRE) measurements from VLSI chips. The performance of the systems is compared in order to understand the figures of merit that a single-photon detector should have to enable the acquisition of time resolved emission waveforms for ultra-low voltage applications. We will show that measurements down to a new World record low 0.4 V supply voltage were made possible by a careful optimization of the detector front-end electronics. We also characterized the emission from devices with different threshold voltages in order to understand how the emission contributions depend on this parameter and how this affects the resulting waveform SNR.
Two-dimensional coarsening and phase separation in thin polymer solution films (1997)

A comprehensive experimental study on the late stages of phase separation in two dimensions was performed by phase separating thin (1.5 and 10 \ensuremath{\mu}m) films of off- and near-critical polymer solutions. The resulting domain-size growth rate (coarsening rate) of the dispersed phase was directly measured for several systems using optical microscopy. Domain sizes of off-critical solutions coarsen predominantly via Ostwald ripening, growing approximately as ${\mathrm{Kt}}^{1\mathrm{/}3}$ , regardless of system. For near-critical solutions, domain sizes grow approximately as ${\mathrm{Kt}}^{1\mathrm{/}3}$ at early times, with coarsening via both coalescence and Ostwald ripening, and feature a crossover to an ultimate ${\mathrm{t}}^{2\mathrm{/}3}$ growth rate. The crossover domain size decreases with increasing quench depth in a manner consistent with a transition from a thermally driven to a flow-driven coarsening mechanism. In general, K increases with area fraction of the dispersed phase for a given off-critical or near-critical system. Both average and crossover domain sizes increase with increasing film thickness, and coalescence is significantly dependent on film thickness while Ostwald ripening is not. The substrate polarity does not greatly affect off-critical coarsening, although near-critical coarsening (particularly near the crossover) is greatly affected. Other effects of polymer molecular weight, solvent viscosity, and quench depth are discussed.
In Situ Causticizing for Black Liquor Gasification (2005)

Black liquor gasification offers a number of attractive incentives to replace Tomlinson boilers but it also leads to an increase in the causticizing load. Reasons for this have been described in previous reports (FY04 ERC, et.al.). The chemistries have also been covered but will be reviewed here briefly. Experimental results of the causticizing reactions with black liquor are presented here. Results of the modeling work were presented in detail in the Phase 1 report. They are included in Table 2 for comparison but will not be discussed in detail. The causticizing agents were added to black liquor in the ratios shown in Table 1, mixed, and then spray-dried. The mixture ratios (doping levels) reflect amount calculated from the stoichiometry above to achieve specified conversions shown in the table. The solids were sieved to 63-90 microns for use in the entrained flow reactors. The firing conditions are shown in Table 2. Pictures and descriptions of the reactors can be found in the Phase 1 annual report. Following gasification, the solids (char) was collected and analyzed by coulometric titration (for carbonate and total carbon), and by inductively coupled plasma emission spectroscopy (ICP) for a wide array of metals.
Contributions of CO2, O2 and H2O to the Oxidative Stability of Solid Amine Direct Air Capture Sorbents at Intermediate Temperature (2023)

Aminopolymer-based sorbents are preferred materials for extraction of CO2 from ambient air (direct air capture of CO2, or DAC) owing to their high CO2 adsorption capacity and selectivity at ultra dilute conditions. While those adsorptive properties are important, the stability of a sorbent is a key element in developing high-performing, cost-effective, and long-lasting sorbents that can be deployed at scale. Along with process upsets, environmental components such as CO2, O2, and H2O may contribute to long-term sorbent instability. As such, unraveling the complex effects of such atmospheric components on sorbent lifetime as they appear in the environment is a critical step to understanding sorbent deactivation mechanisms and designing more effective sorbents and processes. Here, PEI/Al2O3 sorbent is assessed over continuous and cyclic dry and humid conditions to determine the effect of the co-presence of CO2 and O2 on stability at an intermediate temperature of 70 °C. Thermogravimetric and elemental analysis in combination with in situ HATR-IR spectroscopy are performed to measure the extent of deactivation, elemental content, and molecular level changes in the sorbent due to deactivation. The thermal/thermogravimetric analysis results reveal that incorporating CO2 with O2 accelerates sorbent deactivation using these sorbents in dry and humid conditions compared to CO2-free air in similar conditions. In situ HATR-IR spectroscopy results of PEI deactivation under a CO2-air environment show the formation of primary amine species in higher quantity (compared to conditions without O2 or CO2), which arise due to C-N bond cleavage at the primary and secondary amine due to oxidative degradation. We hypothesize the formation of bound CO2 species such as carbamic acids catalyze C-N cleavage reactions in the oxidative degradation pathway by shuttling protons, resulting in a lower activation energy barrier for degradation, as probed by metadynamics simulations. In the cyclic experiment after 30 cycles, results show a gradual loss in stability (dry: 29%, humid: 52%) under CO¬2 containing air (0.04% CO2/21% O2 balance N2). However, the loss in capacity during cyclic studies is significantly less than continuous deactivation as expected.
A Capitalist Road to Communism (2006)

This article was originally published in Theory and Society 15 (5), 1986, pp. 635655. The editors of Basic Income Studies are grateful to Springer Verlag for permission to reprint this article as lead piece in this retrospective. A first draft of this text was written in May 1983 by Van Parijs under the title "The Capitalist Transition to Communism: A Radical Alternative" and was circulated for discussion at the third meeting of the September Group (London, September 1983). It aimed to establish a link between Van Parijs's own first formulation of the argument for basic income ("L'allocation universelle," Ecolo-Infos, 16 February 1983) and van der Veen's formal model of the transition from socialism to communism ("From Contribution to Needs," Acta Politica 19, 1984). A significantly expanded version, co authored by van der Veen and Van Parijs, was finalized in the Spring of 1985, and provided the lead piece for the symposium published in Theory and Society 15(5), 1986, with contributions by Johannes Berger, Joseph Carens, Jon Elster, Alec Nove, Adam Przeworski and Erik Olin Wright, and a reply by van der Veen and Van Parijs ("Universal Grants Versus Socialism"). The piece was subsequently republished, in the original or in translation, in Van Parijs's Marxism Recycled (Cambridge, 1993), in Umbau des Sozialstaats (Opielka and Ostner, eds., Essen, 1987,) and in Zona Abierta (46/47, 1988).
En route to next-generation nerve repair: static passive magnetostimulation modulates neurite outgrowth (2023)

<i>Objective</i>. Regeneration of damaged nerves is required for recovery following nervous system injury. While neural cell behavior may be modified by neuromodulation techniques, the impact of static direct current (DC) magnetic stimulation remains unclear.<i>Approach</i>. This study quantifies the effects of DC magnetostimulation on primary neuronal outgrowth<i>in vitro</i>. The extension of neurites of dorsal root ganglia (DRG) subjected to two different low-strength (mT) static magnetic flux configurations was investigated.<i>Main results</i>. After 3 d of 1 h in-plane (IP) magnetic field stimulation, a 62.5% increase in neurite outgrowth area was seen relative to unstimulated controls. The combined action of in-plane + out-of-plane (IP + OOP) magnetic field application produced a directional outgrowth bias parallel to the IP field direction. At the same time, the diverse magnetic field conditions produced no changes in two soluble neurotrophic factors, nerve growth factor and brain-derived neurotrophic factor, released from resident glia.<i>Significance</i>. These results demonstrate the potential for DC magnetostimulation to enhance neuronal regrowth and improve clinical outcomes.
Etude des mecanismes de conduction electrique et de l'anisotropie de resistivite dans les differentes phases magnetiques du compose la2cuo4 (1991)

L'etude des proprietes de transport et l'anisotropie de resistivite dans les differentes phases magnetiques du compose la2cuo4 constitue l'essentiel de ce travail. Pour ce faire j'ai ete amene a developper une extension de la methode de montgomery permettant, malgre la forte anisotropie de ce compose, de deconcoluer precisement les differentes composantes du tenseur de conductivite. La distinction entre les mecanismes de conduction dans les directions parallele et perpendiculaire aux plans cuo#2 de ce materiau, a permis de mettre en evidence, d'une part, que son comportement bidimensionnel est du a la delocalisation de porteurs extrinseques a l'interieur des plans cuo2, et d'autre part, que la localisation de ces porteurs a basse temperature induit une conduction a caractere tridimensionnel. En outre, la variation des composantes du tenseur de conductivite avec l'ordre magnetique montre l'existence d'un couplage magnetique entre les porteurs et les spins du reseau cristallin. En particulier, les differences entre les mecanismes de conduction observes dans les phases ferromagnetique cache et ferromagnetique faible de ce compose apparaissent liees a une modification, par le changement d'ordre magnetique, de la structure de bande (lors de la transition ferromagnetique cache-ferromagnetique faible on observe: dans les plans, une diminution du gap semi-conducteur extrinseque; et dans la direction perpendiculaire, le passage d'une conduction de type par saut a une conduction de type active)
