Time–temperature–transformation cure diagrams of phenol–formaldehyde and lignin–phenol–formaldehyde novolac resins (2010)

Abstract In this study, the time–temperature– transformation (TTT) cure diagrams of the curing processes of several novolac resins were determined. Each diagram corresponded to a mixture of commercial phenol–formaldehyde novolac, lignin–phenol–formaldehyde novolac, and methylolated lignin–phenol–formaldehyde novolac resins with hexamethylenetetramine as a curing agent. Thermomechanical analysis and differential scanning calorimetry techniques were applied to study the resin gelation and the kinetics of the curing process to obtain the isoconversional curves. The temperature at which the material gelled and vitrified [the glass‐transition temperature at the gel point ( gel T g )], the glass‐transition temperature of the uncured material (without crosslinking; T g 0 ), and the glass‐transition temperature with full crosslinking were also obtained. On the basis of the measured of conversion degree at gelation, the approximate glass‐transition temperature/conversion relationship, and the thermokinetic results of the curing process of the resins, TTT cure diagrams of the novolac samples were constructed. The TTT diagrams showed that the lignin–novolac and methylolated lignin–novolac resins presented lower T g 0 and gel T g values than the commercial resin. The TTT diagram is a suitable tool for understanding novolac resin behavior during the isothermal curing process. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
Energy efficient base station maximization switch off scheme for LTE-advanced (2012)

In this paper, we introduce a solution to a maximization problem for switching off Base Stations in an LTE-Advanced wireless network. Our scheme exploits the existence of idle periods in a cellular network during “night zone”, when the traffic load is low. This work focuses on finding the optimal combination of switched on and off Bases Stations leading to the maximum energy saving. In addition, the major goal lies on increasing the energy efficiency by optimizing the power utilization of the Base Stations without sacrificing the offered Quality of Service. The proposed solution achieves significant energy saving and its performance is evaluated by means of analytical model, as well as simulations results.
[Constitutive glucose-6-phosphate dehydrogenase in mutants utilizing glucose, which are derived from cryptic wildtype strains]. (1969)

Von Wildtyppopulationen von Hydrogenomonas H 16 und anderen Stammen, die lediglich Fructose, aber nicht Glucose zu verwerten vermogen, wurden Glucose verwertende Mutanten isoliert. Samtliche Mutanten stimmen in zwei Merkmalen uberein: 1. sie bilden Glucose-6-phosphat-Dehydrogenase konstitutiv und 2. die Substratsattigungskurve der Veratmung von Glucose verlauft flacher als die fur Fructose. Wahrend die Atmungsrate bei 1,66 mM Fructose schon maximal ist, erreicht die Veratmung von Glucose bei 1,66 mM Glucose erst 15 bis 55%. Die Beziehungen zwischen diesen pleiotropen Effekten (Glucoseverwertung und konstitutive Bildung der Glucose-6-phosphat-Dehydrogenase) sind unbekannt.
Enhanced 3-O-sulfation of galactose in Asn-linked glycans and Maackia amurenesis lectin binding in a new Chinese hamster ovary cell line (2001)

We report the characterization of two Chinese hamster ovary cell lines that produce large amounts of sulfated N-linked oligosaccharides. Clones 26 and 489 were derived by stable transfection of the glycosaminoglycan-deficient cell mutant pgsA-745 with a cDNA library prepared from wild-type cells. Peptide:N-glycanase F released nearly all of the sulfate label, indicating that sulfation had occurred selectively on the Asn-linked glycans. Hydrazinolysis followed by nitrous acid treatment at pH 4 and borohydride reduction yielded reduced sulfated disaccharides that comigrated with standard Gal3SO4beta1-4anhydromannitol. The disaccharides were resistant to periodate oxidation but became sensitive after the sulfate group was removed by methanolysis, indicating that the sulfate was located at C3 of the galactose residues. Maackia amurensis lectin bound to the sulfated glycopeptides on the cell surface and in free form, even after sialidase treatment. This finding indicates that the lectin requires only a charged group at C3 of the galactose unit and not an intact sialic acid. Growth of cells with chlorate restored sialidase sensitivity to lectin binding, indicating that sulfation and sialylation occurred largely at the same sites. The enhanced sulfation was due to elevated sulfotransferase activity that catalyzed transfer of sulfate from phosphoadenosine-5'-phosphosulfate to Galbeta1-4(3)GlcNAcbeta-O-naphthalenemethanol.
Frauen in Spitzengremien großer Unternehmen weiterhin massiv unterrepräsentiert (2010)

Vorstände und Aufsichtsräte großer Unternehmen in Deutschland werden nach wie vor von Männern dominiert - mit erdrückender Mehrheit. Das zeigt die aktuelle Studie des DIW Berlin. Lediglich 2,5 Prozent aller Vorstandsmitglieder der 200 größten Unternehmen (ohne Finanzsektor) sind gegenwärtig Frauen. In den Aufsichtsräten nehmen Frauen ein Zehntel aller Sitze ein. Ähnlich sieht die Lage in Vorständen und Aufsichtsräten des Finanzsektors aus. In den 100 größten Banken sind 2,6 Prozent, in den 62 größten Versicherungen 2,8 Prozent aller Vorstandsmitglieder Frauen. Der Frauenanteil in den Aufsichtsräten liegt jedoch höher als bei den Top-200-Unternehmen: 16,8 Prozent bei den Banken und Sparkassen und 12,4 Prozent bei den Versicherungen. Insgesamt sind rund drei Viertel der Frauen mit Sitz in einem Aufsichtsrat von Arbeitnehmervertretungen entsandt und erhalten damit aufgrund von Mitbestimmungsregelungen ihr Mandat. Trotz einiger positiver Beispiele hat sich die Situation in den Spitzengremien insgesamt in den letzten Jahren kaum geändert. Es bleibt abzuwarten, ob der im Koalitionsvertrag der Regierungsparteien 2009 vereinbarte Stufenplan zur Erhöhung des Anteils von Frauen in Führungspositionen ein größerer Erfolg wird als die Selbstverpflichtung der Unternehmen aus dem Jahr 2001. Deren Umsetzung kann in Bezug auf die Besetzung von Spitzengremien in den großen Unternehmen der Privatwirtschaft als gescheitert gelten.
Induction of mild intracellular redox imbalance inhibits proliferation of CaCo‐2 cells (2001)

Intracellular redox status plays a critical role in cell function, such as proliferation. Oxidative stress, which elicits redox imbalance, also affects cell growth. Therefore, it is often difficult to distinguish the effects of redox imbalance from those of oxidative stress. The objective of this study was to determine the role of redox imbalance independent of reactive oxygen species (ROS) production, in proliferation of human colonic CaCo-2 cells. Low concentrations of diamide plus 1,3-bis(2 chloroethyl)-1-nitrosourea (BCNU) increased intracellular GSSG and decreased GSH and the GSH:GSSG ratio. These changes occurred within 30 min, which preceded a decrease in thymidine incorporation at 6 and 24 h. ROS formation was not detected under these conditions. This suppression of cell proliferative activity was attenuated by N-acetyl cysteine, in parallel with restoration of the intracellular GSH redox status. dl-buthionine-[S, R]-sulfoximine (BSO) decreased intracellular GSH level, but did not change the GSH:GSSG ratio. BSO alone had no effect on cell proliferation, but its presence exaggerated the suppressive effect of diamide plus BCNU. Flow cytometric analysis showed that cells were arrested at G1-to-S transition and G2/M phase. Collectively, this study shows that mild intracellular redox imbalance inhibited cell proliferation independent of ROS generation. Moreover, cells with compromised cellular GSH were susceptible to redox imbalance-induced inhibition of proliferation.
(+)-Larreatricin hydroxylase, an enantio-specific polyphenol oxidase from the creosote bush ( <i>Larrea tridentata</i> ) (2003)

An enantio-specific polyphenol oxidase (PPO) was purified approximately 1,700-fold to apparent homogeneity from the creosote bush (Larrea tridentata), and its encoding gene was cloned. The posttranslationally processed PPO ( approximately 43 kDa) has a central role in the biosynthesis of the creosote bush 8-8' linked lignans, whose representatives, such as nordihydroguaiaretic acid and its congeners, have potent antiviral, anticancer, and antioxidant properties. The PPO primarily engenders the enantio-specific conversion of (+)-larreatricin into (+)-3'-hydroxylarreatricin, with the regiochemistry of catalysis being unambiguously established by different NMR spectroscopic analyses; the corresponding (-)-enantiomer did not serve as a substrate. This enantio-specificity for a PPO, a representative of a widespread class of enzymes, provides additional insight into their actual physiological roles that hitherto have been difficult to determine.
The Reaction between Powder and Liquid Medium at Spark Discharge Point (1977)

When a spark discharge takes place at the contact points of pellets (metal, alloy or graphite) dipped in the liquid medium (pure water or oil), the powder produced from the pellets reacts with the medium at the spark points.This paper describes stoichiometrically the reaction between the powder and the liquid medium at the spark points by means of mass balance being based on the quantity of the cracked medium, the quantity of gas and powder produced, composition of gas, and the property of powder.The results are summarized as follows:1) WC-Co powder produced at the spark points reacted with water and 36.2% of carbon in WC-Co powder was changed into CO2 and CO gases by dicarburization while metallic components were partially oxidized.2) The Aluminum powder reacted with OH-radical and formed Al(OH)3. The reaction took place in short supply of OH-radical by 20.1 % for its theoretical weight at the spark points.3) The Tungsten Carbide was decarburized by its autolysis at the spark points in the oil medium. 11.4% of carbon was decarburized.
Pore Networks in Holocene Carbonate Sediments (1981)

ABSTRACT Permeabilities of Holocene carbonate sediments from Florida and the Bahamas, determined for 74 samples by water flow rates in a variable-head permeameter, range from 0.6 to 57,000 millidarcies. Porosities range from 40 to 78 percent. These parameters are related to depositional texture as follows: Table The muddiest sediments (i.e., the finest-grained) have the highest porosities but lowest permeabilities; this negative correlation between porosity and permeability is the reverse of the situation found in carbonate rocks, even as young as Pleistocene. High porosity and low permeability in sediments show a strong correlation with percentage of fines (<62 µm). From capillary pressure curves it is inferred that many of the pore throats of muddy carbonate sediments are less than 1 µm in diameter, at least after drying. Measured permeabilities are used to calculate cementation rates for simple models of upper phreatic zone cementation; the calculated rates would require excessive time to produce the degree of cementation seen in Late Pleistocene rocks of Florida and the Bahamas. The amounts of rainfall and evaporation are the most important factors in the degree of cementation.
Nutritional Muscular Dystrophy in Calves. II. Addition of Selenium and Tocopherol to a Basal, Dystrophogenic Diet Containing Cod-Liver oil (1960)

Nutritional muscular dystrophy was produced experimentally in Holstein-Friesian calves. The addition of cod-liver oil to the diet caused an intensification of Zenker's degeneration in the muscles of the tocopherol-deficient calves. One p.p.m, of selenium added to the basal diet did not prevent muscular dystrophy. The addition of 200 rag. of water-dispersible d-alpha-tocopheryl acetate per calf per day completely prevented the development of muscular dystrophy in all calves so treated. All calves which were not fed tocopherol supplements developed Zenker's degeneration of the skeletal and tongue muscles and degeneration of the Purkinje fibers 02 the heart. Since blood serum magnesium levels declined progressively in all calves in the experiment, it is possible that low blood ~ magnesium levels may work synergistically with low blood tocopherol levels to produce Purkinje fiber degeneration.
Prediction of Print Defect Perception. (2003)

This study examines the prediction of print defect perception (banding) of the human visual system (HVS) by combining detection probabilities of contrast components from wavelet and sinusoidal decompositions of defect patterns. Detection probabilities for basis function components are obtained from subjective tests. Prediction performance is presented in terms of the deviation of the contrast thresholds at the 92 % detection probability obtained from subjective tests on the simulated print defect patterns. Results from tests run on 21 subjects indicate that prediction errors can be obtained on the order of the subjective test variability used to obtain detection probabilities. While the wavelet approach resulted in less systematic error than the sinusoidal approach, both performed about the same once the systematic error was removed. An advantage of the wavelet approach includes having a framework more conducive for modeling independent visual channels of the HVS and for obtaining efficient orthogonal decomposition of the defect patterns.

Aggregate interference with FCC and ECC white space usage rules: Case study in Finland (2011)

In US FCC and in Europe ECC have outlined the rules for TV-band secondary use. In this paper we apply those rules and compute how much white space is available in Finland. The results are expressed in terms of available secondary channels and secondary system capacity. As a secondary system we use cellular networks with different cell sizes. Unfortunately, the current secondary spectrum usage rules do not protect the TV receivers sufficiently well. Even if each individual secondary transmitter obey them, together their aggregate interference can still disrupt the TV reception. We compute how much aggregate interference a secondary network generates if the network is designed either by FCC or ECC rules. We discover that only for a low secondary transmitters' density, the TV reception will not be disturbed. We can conclude that current white space usage rules are not adequate for protecting the TV receivers. There is a need to develop constraints that consider not only secondary transmission powers but also transmitters' density.
Suppression of Interleukin‐12 Production through Endogenously Secreted Interleukin‐10 in Activated Dendritic Cells: Involvement of Activation of Extracellular Signal‐Regulated Protein Kinase (2003)

Our recent study suggested the reverse relationship between the production of interleukin-10 (IL-10) and IL-12 in dendritic cells (DCs) activated by lipopolysaccharide (LPS) or LPS plus interferon (IFN)-gamma. In the present study, a series of experiments were performed to investigate the mechanisms responsible for this reverse relationship. Our results showed that neutralization of the secreted IL-10 by antibody could enhance the production of IL-12. Neutralization of IL-12 by antibody did not affect the IL-10 production. Addition of exogenous IL-10 suppressed the production of IL-12 by activated DCs, and addition of exogenous IL-12 did not affect IL-10 production. TaqMan real-time reverse transcriptase-polymerase chain reaction supported the fact that the observed effects occurred at mRNA transcription level. We also found that LPS or LPS plus IFN-gamma significantly enhanced the phosphorylation of extracellular signal-regulated protein kinase (ERK) and p38 mitogen-activated protein kinase. In addition, inhibition of ERK by PD98059 significantly suppressed IL-10 and increased the IL-12 production. Exogenous IL-10 reversed the upregulated production of IL-12 induced by PD98059. The above findings suggest a unidirectional negative autocrine regulation of IL-12 by IL-10 in activated DCs and that activation of ERK involves the differential production of IL-10 and IL-12 by activated DCs. Thus, the regulation of differential production of IL-10 and IL-12 may play an important role for DCs in priming T helper 1 (Th1) or Th2 in the immune responses.
Bifunctional Electrocatalysis in Pt−Ru Nanoparticle Systems (2008)

Pt-Ru alloys are prominent electrocatalysts in fuel cell anodes as they feature a very high activity for the oxidation of reformate and methanol. The improved CO tolerance of these alloys has been discussed in relation to the so-called ligand and bifunctional mechanisms. Although these effects have been known for many years, they are still not completely understood. A new approach that bridges the gap between single crystals and practical catalysts is presented in this paper. Nanoparticulate model systems attached to an oxidized glassy carbon electrode were prepared by combining both ligand-stabilized and spontaneously deposited Pt and Ru nanoparticles. These electrodes showed very different voltammetric responses for CO and methanol oxidation. The cyclic voltammograms were deconvoluted into contributions attributed to Pt, Ru, and Pt-Ru contact regions to quantify the contribution of the latter to the bifunctional mechanism. Scanning transmission electron microscopy confirmed the proximity of Pt and Ru nanoparticles in the different samples.
Amyloid β protein (Aβ) deposition in chromosome 14–linked Alzheimer's disease: Predominance of Aβ<sub>42(43)</sub> (1996)

Amyloid beta protein (Abeta) deposition was investigated in the frontal cortex of 8 cases of (genetically confirmed) chromosome 14-linked Alzheimer's disease (AD) using the end-specific monoclonal antibodies BA27 and BC05 to detect the presence of Abeta40 and Abeta42(43), respectively. In all patients, Abeta42(43) was the predominant peptide species present. The total amount of Abeta40 and Abeta42(43) deposited was more than twice the amount deposited in cases of sporadic AD of similar disease duration, although the ratio between the extent of Abeta40 and Abeta42(43) deposition was unaltered, compared with sporadic AD. Therefore, (one of) the effects of the mutations in the presenilin 1:PS-1 (S182) gene may be to cause or at least promote an early and excessive deposition of Abeta42(43) within the brain, a property shared with other inherited forms of AD, such as those due to amyloid precursor protein mutations, and Down's syndrome (trisomy 21).
The Transmission Unit and Telephone Transmission Reference Systems (1924)

Consideration is given to the method of determining and expressing the transmission efficiencies of telephone circuits and apparatus, and of the desirable qualifications for a unit in which to express these efficiencies. The ``transmission unit'' described in this paper has been selected as being much more suitable for this purpose under present conditions than the ``mile of standard cable'' which has been generally used in the past.
Emerging Therapeutic Strategies for Targeting Chronic Myeloid Leukemia Stem Cells (2013)

Chronic myeloid leukemia (CML) is a clonal myeloproliferative disorder. Current targeted therapies designed to inhibit the tyrosine kinase activity of the BCR-ABL oncoprotein have made a significant breakthrough in the treatment of CML patients. However, CML remains a chronic disease that a patient must manage for life. Although tyrosine kinase inhibitors (TKI) therapy has completely transformed the prognosis of CML, it has made the therapeutic management more complex. The interruption of TKI treatment results in early disease progression because it does not eliminate quiescent CML stem cells which remain a potential reservoir for disease relapse. This highlights the need to develop new therapeutic strategies for CML to achieve a permanent cure, and to allow TKI interruption. This review summarizes recent research done on alternative targeted therapies with a particular focus on some important signaling pathways (such as Alox5, Hedgehog, Wnt/b-catenin, autophagy, and PML) that have the potential to target CML stem cells and potentially provide cure for CML.
Laser Doping of Chromium and Selenium in p-Type 4H-SiC (2008)

Chromium (Cr) and selenium (Se) are laser doped in silicon carbide (4H-SiC p-type aluminium) to fabricate an embedded light emitting device and to tune the light emission. A near infrared Nd:YAG (1064 nm wavelength) laser source and an organometallic Cr compound (bis (ethyl benzene)-chromium) and organometallic Se compound (dimethyl selenide) were used to laser dope SiC. A p-n junction device structure was created using these dopants. The dopant profiles have been characterized using secondary ion mass spectrometry. Electrical properties were measured using Hall effect measurement. Enhanced diffusivity and solubility with complete activation of dopants was observed for laser doped Cr and Se. Cr and Se are unconventional dopants, which serve as a double donor and a double acceptor respectively, while aluminium (Al) behaves as single acceptor and nitrogen (N) as a single donor in SiC. The defect levels (donor and acceptor) created within the forbidden band gap of SiC due to Se, Cr and Al onsets the donor acceptor pair (DAP) recombination mechanism for luminescence observed in SiC. Electroluminescence studies showed an orange (677 nm) corresponding to Cr-Al and, red (698 nm) and white (380-900 nm) for Se-Al and pure white for Cr-Se-Al. The Cr-Se-Al white light exhibited a correlated color temperature of 4935 K, which compares well to average daylight (5500 K).
