STUDY ON CARBONATION MECHANISM OF STEEL SLAG (2010)

Carbonated exothermic performance,minerals and structure changes before and after carbonation of steel slag were investigated by examining heat evolution of steel slag carbonation,carbonated mineral phases,thermogravimetric changes as well as pore size distribution of steel slag specimens.The results show that the hydrated cumulative heat release of steel slag is 30 J/g in 24 h,but the carbonated accumulative heat is 95 J/g in 1 h.Some carbonate minerals appeared in carbonated steel slag specimens,and the carbon dioxide of 121.8 g could be sequestrated by using per kilogram steel slag in carbonated sample.The porosity of the steel slag specimens decreased from 21.76% to 13.34%,due to the carbonation,resulting in that the corresponding compressive strength increased from 6.69 MPa to 42.14 MPa.The carbonated specimens had a qualified autoclave soundness.
Determining the Dielectric Properties of a Car Tire for an Advanced Tire Monitoring System (2009)

Conventional tire pressure monitoring systems (TPMS) measure the air pressure in each tire of a car with a sensor mounted on the rim. In future, advanced tire monitoring systems (ATMS) will measure additional data like tire temperature, contact area, vertical load, and slip angle. As a consequence, ATMS modules must be mounted directly at the tire tread. Furthermore, tire identification and lifecycle management via radio frequency identification (RFID) will be enabled. To design appropriate antennas for these applications, it is mandatory to investigate the interaction of antennas with the tire. Therefore we explore the tire structure and the dielectric material properties of the tire rubber. In this contribution the characterization of the dielectric tire materials using an open-ended coaxial probe is presented. We measure the reflection coefficients for each rubber tire layer and determine the relative permittivity and loss tangent by a numerical curve fitting method. The dielectric properties of each rubber layer are measured for a standard and a run-flat tire.
On triazoles. <b>XXXIII</b>. The reaction of potassium triazolyldithiocarbonates with dihaloalkanes (1994)

Abstract The reaction of potassium (5‐amino‐3‐Q‐1,2,4‐triazolyl)dithiocarbonates 2 with 1,ω‐dihaloalkanes 7‐10 to yield ω‐haloalkyldithiocarbonates 11‐12 , ω‐alkylene‐bis(dithiocarbonates) 13‐15 and different by‐products as the corresponding 7,8‐dihydro[1,2,4]triazolo[1,5‐ c ][1,3,5]thiadiazepine‐5(9 H )‐thione ( 16 ), 7,8,9,10‐tetrahy‐dro[1,2,4]triazolo[1,5‐ c ][1,3,5]thiadiazocine‐5‐thione ( 17 ) and 1,7‐dihydro‐5 H ‐1,2,4‐triazolo[1,5‐ c ][1,3,5]thiadi‐azine‐5‐thione ( 22 ) derivatives all three representing novel ring systems were obtained. Repeating the reactions with dipotassium salts 3 the corresponding iminodithietans 18 , imino‐1,3‐dithiolanes 19 and imino‐1,3‐dithianes 20 were obtained. Unexpectively, the imino‐1,3‐dithiolanes ( 19 ) rearranged to the corresponding thiazolidines 24‐27 under rather mild conditions. A possible mechanism is proposed for this rearrangement.
<title>Evanescent Wave Fiber Optic Couplers: Three Methods</title> (1983)

Three methods have been used successfully in fabricating evanescent optical couplers with single mode and multimode optical fibers. These approaches comprise cementing fibers into plates before grinding and polishing, embedding the fibers in lower melting temperature glass before grinding and polishing, and stretching adjacent fibers while heating them. Comparisons are made among the couplers produced by the three methods with regard to stability of the coupling ratio with ageing, changes in temperature and changes in light polarization.
Porous Cellulose Materials from Nano Fibrillated Cellulose (2012)

In the first part of this work a novel type of low-density, sponge-like material for the separation of mixtures of oil and water has been prepared by vapour deposition of hydrophobic silanes on ultra-porous nanocellulose aerogels. To achieve this, a highly porous (&gt; 99 %) nanocellulose aerogel with high structural flexibility and robustness is first formed by freeze-drying an aqueous dispersion of the nanocellulose. The density, pore size distribution and wetting properties of the aerogel can be tuned by selecting the concentration of the nanocellulose dispersion before freeze-drying. The hydrophobic light-weight aerogels are almost instantly filled with the oil phase when they selectively absorb oil from water, with a capacity to absorb up to 45 times their own weight. The oil can also be drained from the aerogel and the aerogel can then be subjected to a second absorption cycle.In the second part of the work a novel, lightweight and strong porous cellulose material has been prepared by drying aqueous foams stabilized with surface-modified NanoFibrillated Cellulose (NFC). Confocal microscopy and high-speed video imaging show that the long-term stability of the wet foams can be attributed to the octylamine-coated, rod-shaped NFC nanoparticles residing at the air-liquid interface which prevent the air bubbles from collapsing or coalescing. Careful removal of the water yields a porous cellulose-based material with a porosity of 98 % and a density of 30 mg cm-3. These porous cellulose materials have a higher Young’s modulus than other cellulose materials made by freeze drying and a compressive energy absorption of 56 kJ m-3 at 80 % strain. Measurements with an autoporosimeter reveal that most pores are in the range of 300 to 500 μm.
The Rac1 C-terminal Polybasic Region Regulates the Nuclear Localization and Protein Degradation of Rac1 (2004)

We observed evolutionary conservation of canonical nuclear localization signal sequences (K(K/R)X(K/R)) in the C-terminal polybasic regions (PBRs) of some Rac and Rho isoforms. Canonical D-box sequences (RXXL), which target proteins for proteasome-mediated degradation, are also evolutionarily conserved near the PBRs of these small GTPases. We show that the Rac1 PBR (PVKKRKRK) promotes Rac1 nuclear accumulation, whereas the RhoA PBR (RRGKKKSG) keeps RhoA in the cytoplasm. A mutant Rac1 protein named Rac1 (pbrRhoA), in which the RhoA PBR replaces the Rac1 PBR, has greater cytoplasmic localization, enhanced resistance to proteasome-mediated degradation, and higher protein levels than Rac1. Mutating the D-box by substituting alanines at amino acids 174 and 177 significantly increases the protein levels of Rac1 but not Rac1(pbrRhoA). These results suggest that Rac1 (pbrRhoA) is more resistant than Rac1 to proteasome-mediated degradative pathways involving the D-box. The cytoplasmic localization of Rac1(pbrRhoA) provides the most obvious reason for its resistance to proteasome-mediated degradation, because we show that Rac1(pbrRhoA) does not greatly differ from Rac1 in its ability to stimulate membrane ruffling or to interact with SmgGDS and IQGAP1-calmodulin complexes. These findings support the model that nuclear localization signal sequences in the PBR direct Rac1 to the nucleus, where Rac1 participates in signaling pathways that ultimately target it for degradation.
Luminescence enhancement by Si ring resonator structures on silicon on insulator (2008)

Si ring resonators on silicon on insulator show at least 50 times stronger photoluminescence (PL) with sharp peaks than the surrounding Si slab region at room temperature. The frequencies of the PL peaks are well explained by the resonant frequencies of the rings and the intensities are by the ratio of the quality factors of the PL peaks and the modal volumes of resonances. This suggests that the Purcell effect should be responsible for the enhancement.
Automatic sentence generation from images (2011)

For the overwhelming amounts of multimedia used on the Web, methods of search and understanding with sentences are necessary. Representing the contents not only using labels but also using sentences including labels' relations enables users to search with a story and to understand multimedia deeply. However, few existing works describe such sentences because obtaining objects' relations and grammar is difficult. We specifically examine captions of images that are similar to an input image. They are expected to explain the input image to some degree. Therefore, we propose a novel approach to generate a sentential caption for the input image by summarizing those captions. Our experiment using a dataset consisting of images and text demonstrates that the proposed method can generate sentential captions.

Une Vie D'Ambassadrice (1962)

E VEN the most casual reader of French literature has at least a nodding acquaintance with Alphonse Daudet (1840-1897), having read some of the charming Proven~al tales related in his Lettres de mon moulin (1866), or the delightfully humorous and ironic Tartarin de Tarascon (1872).Such a reader, however, may not be aware of the fact that his elder brother, Emest-Louis-Marie
Time-dependent changes in pulmonary surfactant function and composition in acute respiratory distress syndrome due to pneumonia or aspiration (2007)

We concluded that a profound impairment of pulmonary surfactant composition and function occurs in the very early stage of the disease and only gradually resolves over time. These observations may explain why former surfactant replacement studies with a short treatment duration failed to improve outcome and may help to establish optimal composition and duration of surfactant administration in future surfactant replacement studies in acute lung injury.

Hydrogen chemisorption and reaction on GaAs(100) (1990)

We have studied the chemisorption of atomic hydrogen and deuterium on gallium-rich (4×6) and arsenic-rich c(2×8) GaAs(100) reconstructed surfaces using temperature programmed desorption (TPD). Molecular hydrogen (specifically D2) desorption from the gallium-rich (4×6) surface exhibits a peak at 480–510 K, depending on the initial coverage. By comparing results from the different reconstructions we conclude that the desorption of molecular hydrogen primarily arises from surface GaHx species. The arsenic-rich c(2×8) surface yields a small amount of molecular hydrogen desorption around 660 K, apparently arising from surface AsHx species. In addition to molecular hydrogen, chemisorbed arsine is detected desorbing from both reconstructions around 330–340 K. This result indicates that atomic hydrogen can etch the GaAs surface. For the maximum exposure studied, ∼15% of the surface arsenic on the arsenic-rich c(2×8) surface is converted to arsine.
Compliance with treatment in adult patients with cystic fibrosis. (1996)

Non-compliance is universal and should be recognised as normal behaviour. There are no reliable criteria for predicting any patient's level of compliance. Treatment protocols should be planned around individual patient's requirements, modifying treatment ideals where necessary according to the exigency and pattern of that patient's lifestyle.
Chin Augmentation Using Minimally Invasive Technique and Bioplastique (1995)

The plethora of problematic techniques for improving minor chin recessions has left the plastic surgeon inevitably uncertain of the most effective remedy. Research we began in 1968 has led us to the development of a new biphasic polymer and minimally invasive implantation techniques aimed at solving the soft-tissue deficiency dilemma. Bioplastique consists of inert, textured particles of critical dimension dispersed within a bioexcretable gel vehicle. Previous experimentation in rabbit ears has shown that the gel component is rapidly phagocytosed, excreted, and replaced by a fibrin matrix within 3 days. The matrix is then replaced by host collagen, gradually forming a stable encasement around each microparticle. Further evaluation has revealed that the implant resists migration and absorption. Based on these encouraging results, a clinical phase was initiated. Thirteen patients lacking chin prominence have subsequently been improved with Bioplastique implants. The infection rate was 0 percent, and other complications were minor. At 26 months, no evidence of migration or absorption has been observed, and the aesthetic results remain.
Platelet ADP receptor and alpha 2-adrenoreceptor interaction. Evidence for an ADP requirement for epinephrine-induced platelet activation and an influence of epinephrine on ADP binding. (1986)

The nucleotide affinity analog 5'-p-fluorosulfonylbenzoyl adenosine (FSBA) is a potent irreversible inhibitor of ADP-mediated platelet activation. Utilizing this compound, the role of ADP in epinephrine-mediated platelet activation was evaluated. Pretreatment of platelets with FSBA under conditions producing covalent incorporation was able to completely block epinephrine-stimulated aggregation of human platelets. In addition, the exposure of latent fibrinogen-binding sites by epinephrine was also inhibited in platelets modified by FSBA. The inhibition of epinephrine-mediated activation of the cells was time dependent, reflecting the need for covalent modification of the ADP receptor by FSBA. The inhibitory effect of FSBA was not due to effects on the affinity of binding methyl [3H]yohimbine or the number of platelet alpha 2-adrenergic receptors. Studies of the effect of epinephrine on the ability of ADP to protect against FSBA incorporation demonstrated that epinephrine can increase the affinity of ADP for its receptor 10-fold without affecting the total amount of FSBA covalently bound. This effect of epinephrine is mediated through the alpha 2-adrenoreceptor since the effect can be reversed by the competitive antagonist, methyl yohimbine. These results suggest that promotion of platelet aggregation and the exposure of fibrinogen receptors by epinephrine is dependent on ADP. The mechanism by which epinephrine renders low concentrations of ADP effective appears to be mediated by an increased avidity of the ADP receptor for the nucleotide.

A Bi-Directional Magnetic Micropump on a Silicon Wafer (1996)

A new electromagnetically driven peristaltic micropump on a silicon wafer with a low driving voltage less than 3 volts has been designed, fabricated, and tested. To construct the micropump, electromagnets on a Pyrex glass wafer and micropump parts on a silicon wafer are separately fabricated, and then assembled together using low temperature polymer bonding techniques. This new fabrication technique of magnetic microactuators using low temperature post-bonding techniques provides a flexible and unique approach in realizing various magnetic MEMS devices. The realized magnetic micropumps have been functionally operated in peristaltic motions with a DC 300 mA and 3 volts allowing bi-direction pumping flows. The maximum attainable flow rate was approximately 20 l/min at 5 Hz. In this work, a new electromagnetically driven bi-directional micropump has been successfully realized on silicon wafers.

The use of baseline covariates in crossover studies (2009)

It is our experience that in many settings, crossover trials that have within-period baseline measurements are analyzed wrongly. A "conventional" analysis of covariance in this setting uses each baseline as a covariate for the following outcome variable in the same period but not for any other outcome. If used with random subject effects such an analysis leads to biased treatment comparisons; this is an example of cross-level bias. Using a postulated covariance structure that reflects the symmetry of the crossover setting, we quantify such bias and, at the same time, investigate potential gains and losses in efficiency through the use of the baselines. We then describe alternative methods of analysis that avoid the cross-level bias. The development is illustrated throughout with 2 example trials, one balanced and orthogonal and one highly unbalanced and nonorthogonal.
Antiangiogenic Effect of Curcumin in Pure Versus in Extract Forms (2008)

Curcumin isolated from turmeric (Curcuma longa L., Zingaberaceae) root was found to be anti-angiogenic in a human tissue-based angiogenesis assay. As a liposoluble compound, curcumin can be extracted from turmeric root with organic solvents such as ethanol or acetone. Curcumin in its pure form has poor solubility in water, potentially limiting its medicinal use for humans when it is taken orally or injected. This study attempted to investigate the possibility of improving curcumin's low solubility using an extract as a carrier. This would maintain anti-angiogenic properties with improved water-solubility. Experiments were undertaken to determine the extraction efficiency of different solvents for curcumin. Anti-angiogenic activities of curcumin in its pure form and in extracts were compared as a general trend ethanol or acetone was more efficient in extracting curcumin than their aqueous counterparts. Using 50 and 70% aqueous ethanol as well as 70% aqueous acetone yielded significantly more turmeric extracts by weight than absolute acetone, which was the lowest. Conversely, turmeric extracts extracted with 95% ethanol and absolute acetone contained significantly higher curcumin concentrations than water extract, which was the lowest. Combining the higher extract yield and highest curcumin concentrations in the extract, 95% ethanol gave the highest yield of single entity curcumin. In the angiogenesis assay, pure curcumin at the concentration of 85 μM (in 1% ethanol v/v) in the culture medium totally suppressed angiogenic responses. In contrast, a curcumin concentration of 18.5 μM (in the form of 100 μg/ml turmeric extract) achieved the same total inhibition of angiogenesis in culture. This nearly 5 fold gap reflected the unaccounted involvement of other antiangiogenic compounds including curcumin derivatives, and/or enhancement of curcumin by non-antiangiogenic compounds in the extract. This finding suggests that curcumin in the form of extracts be potentially more pharmacologically active than pure curcumin. Further investigations of this hypothesis and possible interactions are warranted. © 2008 Informa UK Ltd.
Systematic classification of CDR‐L3 in antibodies: Implications of the light chain subtypes and the V<sub>L</sub>–V<sub>H</sub> interface (2008)

Antibody modeling is widely used for the analysis of antibody-antigen interactions and for the design of potent antibody drugs. The antibody combining site is composed of six complementarity determining regions (CDRs). The CDRs, except for CDR-H3, which is the most diverse CDR, form limited numbers of canonical structures, which can be identified from the amino acid sequences. A method to classify the CDR-H3 structure from its amino acid sequence was previously proposed. However, since those CDR structures were classified, many more antibody crystal structures have been determined. We performed systematic analyses of the CDR-L3 structures and found novel canonical structures, and we also classified a previously identified canonical structure into two subtypes. In addition, two differently defined canonical structures in the kappa and lambda subtypes were classified into the same canonical structure. We also identified a key residue in CDR-L3, which determines the conformation of CDR-H3. Several analyses of CDR-L3 loops longer than nine residues were performed. These new findings should be useful for structural modeling and are eventually expected to accelerate the design of antibody drugs.
Analyzing patterns of information cascades based on users' influence and posting behaviors (2012)

Nowadays people can share useful on social networking sites such as Facebook and Twitter. The is spread over the networks when it is forwarded or copied repeatedly from friends to friends. This phenomenon is so called information cascade, and has been studied long time since it sometimes has an impact on the real world. Various social activities tends to have different ways of cascade on the social networks. Our focus in this study is on characterizing the cascade patterns according to users' influence and posting behaviors in various topics. The cascade patterns could be useful for various organizations to consider the strategy of public relations activities. We explore four measures which are cascade ratio, tweet ratio, time of tweet, and exposure curve. Our results show that hashtags in different topics have different cascade patterns in term of these measures. However, some hashtags even in the same topic have different cascade patterns. We discover that such kind of hidden relationship between topics can be surprisingly revealed by using only our four measures rather than considering tweet contents. Finally, our results also show that cascade ratio and time of tweet are the most effective measures to distinguish cascade patterns in different topics.
