Adsorption of Acid Dyes from Aqueous Solution on a Chitosan-cotton Composite Material Prepared by a New Pad-dry Process (2011)

In this paper, we developed a method that may be considered as an easy and economical way to prepare chitosan-cotton composite (CH-cotton) materials using an electrolytes-free pad-dry process in which the cure step was performed in an oven microwave to provide a cotton fabric with greatly enhanced affinity for acid dyes. Evidence of successful interaction between cotton and CH through formation of hydrogen bonding and/or ion dipole interactions was analysed by FTIR spectroscopy. Influence of cure time onto the weight per surface unit of samples has been studied and five CH-cotton composite materials with different %CH content (I-V) were prepared. Crosslinking of cellulosic chain molecules of cotton fiber through CH segments was confirmed by Wrinkle Recovery Angle (WRA) and Tensile properties measurements. CH-cotton samples were then tested as adsorbent of four acid dyes from no-electrolytes aqueous solution [Indigo Carmine (AB74), Acid Red 183 (AR183), Acid Blue 161 (AB161) and Acid Yellow 17 (AY17)]. Results were monitored using, reflectance spectro-colorimeter and spectrophotometer analyses. Data obtained with treated cotton showed better dye exhaustion than obtained with untreated one. The modelling of the adsorption isotherms was performed by Langmuir equation and the thermodynamic parameters were evaluated. Globally, the lack of affinity of cotton for acid dyes is widely overcome by the use of low %CH content ranging from 0.079 to 0.515
Elastoplastic Contact Conductance Model for Isotropic Conforming Rough Surfaces and Comparison With Experiments (1996)

A New thermal elastoplastic contact conductance model for isotropic conforming rough surfaces is proposed. This model is based on surface and thermal models used in the Cooper, Mikic, and Yovanovich plastic model, but it differs in the deformation aspects of the thermal contact conductance model. The model incorporates the recently developed simple elastoplastic model for sphere-flat contacts, and it covers the entire range of material behavior, i.e., elastic, elastoplastic, and fully plastic deformation. Previously data were either compared with the elastic model or the plastic model assuming a type of deformation a priori. The model is used to reduce previously obtained isotropic contact conductance data, which cover a wide range of surface characteristics and material properties. For the first time data can be compared with both the elastic and plastic models on the same plot. This model explains the observed discrepancies noted by previous workers between data and the predictions of the elastic or plastic models.
The mechanism of acyl phosphonate reactions. Part I. The kinetics of the solvolyses of benzoyl and p-toluoyl phenylphosphonates in aqueous dioxan (1973)

Rate constants have been determined for the neutral hydrolysis of benzoyl phenylphosphonate in 5, 20, and 40% aqueous dioxan and p-toluoyl phenylphosphonate in 20% dioxan. Acid catalysis, salt effects, and the addition of nucleophiles have been investigated in 20% dioxan at 295·5 K. It is concluded that the mechanism of hydrolysis is bimolecular addition to the acyl carbon atom to form a tetrahedral intermediate prior to phosphonate ion elimination.
X-Ray Imaging With Two-Dimensional Charge-Coupled Device (CCD) Arrays (1984)

Two basic approaches to digital radiography have been thoroughly investigated in the last decade. In one, the traditional video chain is modified, and the output of the camera is digitized and analyzed by a computer to produce an image of the area of the body being examined. The other approach uses a linear detector array to generate a sequential series of line images as the array is scanned across the area being observed; the line images are then combined by a computer to form a two-dimensional image. We are investigating the characteristics of a third method, a prototype digital radiography system in which two-dimensional diode arrays (CCD) are fiberoptically coupled directly to either a scintillating fiberoptic plate or to a fluorescent screen. In this paper we describe the- concepts and design configuration of this approach, as well as preliminary results from several phantom studies. Our results indicate that high resolution, high signal-to-noise ratio imaging can be attained with this method.
Infection with Methicillin-resistant Staphylococcus aureus after Carbon Dioxide Resurfacing of the Face (1998)

We propose that it would be helpful for patients undergoing CO2 laser resurfacing to have their nares cultured to see if they are staphylococcal carriers. If a patient is found to be a carrier, mupiricin ointment can be used preoperatively treat to the nares, to help decrease the risk of infection of the skin from this potential source.

Interference based W-band single-pole double-throw with tunable liquid crystal based waveguide phase shifters (2017)

This work presents an interference based W-band single-pole double-throw (SPDT) in rectangular waveguide and liquid crystal technology. In radiometers, this kind of SPDT can be used e.g. for switching to the calibration load for power calibration. The SPDT is designed with an E-plane power divider, two different paths for the phase shifting regions, being separated by 30 mm to provide enough space for the used magnets for proof-of-concept, and a coupled line combiner, where the interference is taking place. Rexolite 1422 is serving as liquid crystal cavity. The matching is better than -12 dB between 88 GHz to 110 GHz, except a peak around 102 GHz. The insertion loss is less than 3 dB between 89 GHz to 105 GHz, while exhibiting an isolation of at least 9 dB in this frequency range. From 90 GHz to 100 GHz, isolation is even between 10 dB to 12 dB.
An Assigned Color Depth Packing Method With Centralized Texture Depth Packing Formats for 3D VR Broadcasting Services (2018)

The ability to distribute 3D video and audio in traditional television channels is key to deliver three dimensional (3D) virtual reality (VR) broadcasting services, which allows a limited number of connected players and unlimited number of audiences to enjoy 3D video, audio, and passive interactions. Recently, the centralized texture depth packing (CTDP) formats with color depth packing are proposed for delivering 3D videos. In this paper, we revise the procedure of CTDP computation and introduce an assigned color depth packing method that packs the depth information of VR in RGB color space and depacks it in YCbCr or RGB color space even if the video coder is conducted in YCbCr 4:2:0 and 4:2:2 chroma formats. Under uncoded and coded conditions, the performances of the depacked depth, texture, and synthesized frames of the proposed method are compared to those of the existed packing algorithms. Finally, a trial 3D video and VR broadcasting system based on the left-ad-right CTDP format have been tested in Hsin Yeong, a cable company in Taiwan.
Actinomycin D Binds Strongly and Dissociates Slowly at the dGpdC Site with Flanking T/T Mismatches (1996)

Comparative electrophoretic, thermal denaturation, and spectroscopic studies with dodecamers of the form d(ATTA-XGCX-TAAT) and their self-complementary counterparts suggest that actinomycin D (ACTD) binds strongly to a 5'GC3' site with flanking T/T mismatches and moderately to that with C/C mismatches but weakly to those with other G/G or A/A mismatches. The relative binding order is found to be T/T > C/C > G/G > A/A. The ACTD binding affinity for the GC site with T/T mismatches is comparable to the strong binding of self-complementary-XGCY-sequences. Both the ACTD association and dissociation kinetics at the GC site with flanking T/T mismatches require two-exponential fits. The slow component of the association rates is slower than those of the self-complementary sequences, whereas that of the dissociation is only slightly faster than that of the -TGCA- sequence. Interestingly, the slow component of dissociation is decidedly slower than those of -AGCT- and -CGCG- sites and is more than an order of magnitude slower than those with C/C, G/G, and A/A mismatches. These kinetic results are further corroborated by fluorescence measurements using 7-amino-ACTD, a fluorescent analog of ACTD. In addition, fluorescence and absorbance spectral characteristics indicate that the binding mode at the GC site with flanking T/T mismatches resembles those of strong-binding self-complementary -XGCY- sites which are known to be intercalative in nature. The observed slow ACTD dissociation at the T/T-mismatched site suggests that the minor-groove environment near the T/T-mismatched pairs provides favorable interactions with the pentapeptide rings of the drug, whereas the others, especially those of bulkier purine/purine mismatches, result in less favorable interactions.
Distribution of Uronic Acids in Xylans from Various Species of Soft- and Hardwood As Determined by MALDI Mass Spectrometry (2001)

The distribution of 4-O-methylglucuronic acid residues along the polysaccharide chains of xylans isolated from birch, aspen, spruce, pine, and larch was studied here employing matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) analysis of the oligosaccharide mixtures obtained by partial acid hydrolysis. The hydrolyzates thus obtained were analyzed by MALDI-MS or by capillary electrophoresis as well as by size exclusion chromatography in combination with MALDI-MS. In the case of all softwood xylans examined, the major portion of the 4-O-methylglucuronic acid residues were distributed regularly on every seventh or eighth xylose residue, while a minor portion of these residues were attached to adjacent xylose residues in the beta-(1-->4)-D-xylopolysaccharide chains. In contrast, the 4-O-methylglucuronic acid residues in the hardwood xylans examined were found to be distributed irregularly within the xylan. Further support for these experimental findings with the xylans was obtained by simulation of the distribution patterns of the molecular masses of oligosaccharides arising from polysaccharides with the postulated distribution of uronic acid residues.
A Comparative Study of Stress-mediated Immunological Functions with the Adjuvanticity of Alum (2012)

The efficacy of a vaccine is generally dependent on an adjuvant, which enhances the immune functions and alum has been widely used in human immunization. Alum activates the intracellular stress sensors inflammasomes, but whether these are responsible for the adjuvanticity is controversial. The objectives of this investigation were to examine the hypothesis that alum-mediated adjuvanticity is a function of stress and conversely that stress agents will elicit adjuvanticity. The investigation was carried out in BALB/c mice by SC immunization with ovalbumin (OVA) mixed with alum. This elicited inflammasomes, with significant activation of caspase 1, production of IL-1β, and adjuvanticity, demonstrated by enhancing OVA-specific serum IgG antibodies, CD4(+) T cells, and proliferation. The novel finding that alum induced HSP70 suggests that stress is involved in the mechanism of adjuvanticity. This was confirmed by inhibition studies with PES (phenylethynesulfonamide), which disrupts inducible HSP70 function, and inhibited both inflammasomes and the adjuvant function. Parallel studies were pursued with an oxidative agent (sodium arsenite), K-releasing agent (Gramicidin) and a metal ionophore (dithiocarbamate). All 3 stress agents induced HSP70, inflammasomes, and the adjuvant functions. Furthermore, up-regulation of membrane associated IL-15 on DC and CD40L on T cells in the animals treated with alum or the stress agents mediate the interactions between splenic CD11c DC and CD4(+) or CD8(+) T cells. The results suggest that the three stress agents elicit HSP70, a hallmark of stress, as well as inflammasomes and adjuvanticity, commensurate with those of alum, which may provide an alternative strategy in developing novel adjuvants.
Oxidative tyrosylation of high density lipoproteins impairs cholesterol efflux from mouse J774 macrophages: role of scavenger receptors, classes A and B (2002)

Studies were designed to test whether tyrosylation of high-density lipoprotein (HDL(T)) modifies its metabolic features. HDL(T) was less effective than native HDL in promoting cholesterol efflux from J774-AI macrophages. Cell association with fluorescent HDL(T)-apolipoprotein and the uptake of HDL(T)-[(3)H]cholesteryl hexadecyl ether were enhanced by 50% in comparison with native HDL. In addition, neutral cholesterol ester hydrolase (nCEH) activity in J774-AI, which controls the hydrolysis of cholesteryl ester stores to provide free cholesterol for cellular release, declined in the presence of HDL(T). In vitro displacement experiments revealed the ability of HDL(T) to compete with oxidized and acetylated LDL, known as ligands of scavenger receptor (SR) class B type I/II. Similarly, treatment with a blocking antibody to SR-BI/II reduced the cell association of HDL(T) and native HDL by 50%. The addition of polyinosinic acid, an inhibitor of SR class A, reduced the cell association of HDL(T) without affecting that of native HDL. These findings provide evidence that HDL(T) can compete with modified LDL, bind SR-BI/BII and internalize cholesterol ester. Furthermore, the impaired capacity of HDL(T) in promoting cholesterol efflux from J774-AI was accompanied by diminished nCEH and enhanced recognition by SR-AI/II, which appears to involve the transport of cholesterol into cells.

Current Situation and Development of Micro-milling Key Technologies (2012)

Application of the micro-milling technology on the three dimensional precision micro parts manufacturing led to a major technological change in micro manufacturing.Different from MEMS technology and the ultra precision processing technology,it is an effective way for micron-scale micro and intermediate parts with high efficiency,high-precision micro-manufacturing,which is use of traditional milling methods and has unique advantages such as the diversity of workpiece materials and the realization of machining 3D surface.Based on the summary of a lot of literature in our and foreign countries,this thesis summarizes the studies on the research and development of micro milling machine,surface topography,surface roughness,burr of and micro tool wear in micro-milling process.The deficiency of study on the concern technologies of micro milling and the development perspective of this field have been pointed out.
Aspects of Synchronization (1997)

Aspect oriented programming promotes the separation of the different aspects of a system into their natural form. Synchronisation is an important aspect of concurrent object-oriented systems, but treating synchronisation as a single monolithic aspect leads to inflexibility and limited possibilities for reuse. We suggest that synchronisation has a number of different aspects, and introduce the 'synchronisation rings' model which allows the aspects of a synchronised object to be specified independently. By separating the different aspects of synchronisation we can provide flexible, generic implementations of common synchronisation constraints, which can be reused in many different contexts
Effects of material state on the small strain behavior of dry sand (2004)

An energy-injecting virtual-mass (EIVM) resonant column system was employed to investigate the small strain behavior of dry sand; and the effects of effective mean normal stress, density of soil samples, amplitude of shear strain, as well as number of loading cycles on shear modulus and damping ratio are studied. The test results show that the shear modulus increases with effective mean normal stress and soil density, while the damping ratio exhibits the opposite response. Moreover, the effects of effective mean normal stress on the small strain behavior of dry sand are more than those of soil density. As the shear strain increases, the shear modulus become smaller; but the damping ratio become larger. The number of loading cycles has no significant effects on shear modulus, but it influences the damping ratio to a quite extent.
A survey of neurologists on bothersome patient behaviors. (2006)

Some of the bothersome patient behaviors may have deleterious effects on patient care, whereas others may make the practice of medicine unpleasant for physicians. A number of the behaviors may be reduced by providing patients with practice policies. Others are best addressed through ongoing communication and education.
Per-Tone Transmit Antenna Selection with Phase Precoding for OFDM (2011)

If antenna selection in OFDM is done on a per-tone basis, the frequency domain can be exploited to achieve very good performance. However this means that the channel after antenna selection will have discontinuities in the frequency domain. In this paper we present a novel phase precoding that ensures that the channel after antenna selection is smooth enough in the frequency domain for advanced channel estimation. We analyse its performance and show that it is robust to channel estimation and reciprocity errors.
Regulation of tumor necrosis factor ?-mediated apoptosis of rheumatoid arthritis synovial fibroblasts by the protein kinase Akt (2001)

These results indicate that phosphorylated Akt acts as a survival signal in RASF and contributes to the stimulatory effect of TNFalpha on these cells by inhibiting the apoptosis response. This effect was not observed in OASF and may reflect the pathophysiologic changes associated with the proliferating synovium in rheumatoid arthritis.
Compact polarimetry overview and applications assessment (2010)

A synthetic aperture radar (SAR) with hybrid-polarity (CL-pol) architecture transmits circular polarization and receives two orthogonal, mutually coherent linear polarizations, which is one manifestation of compact polarimetry. The resulting radar is relatively simple to implement and has unique self-calibration features and low susceptibility to noise. It also enables maintenance of a larger swath coverage than fully polarimetric SAR systems. A research team composed of various departments of the Government of Canada evaluated this compact polarimetry mode configuration for application to soil moisture estimation, crop identification, ship detection, and sea-ice classification. This paper presents an overview of compact polarimetry, the approach developed for evaluation, and preliminary results for applications important to the Government of Canada. The implications of the results are also discussed with respect to future SAR missions such as the Canadian RADARSAT Constellation Mission, the American DESDynI, and India’s RISAT.
A reverse genetics system for flaviviruses (2013)

Flaviviruses such as Japanese encephalitis virus, West Nile virus, yellow fever virus, dengue virus, and tick-borne encephalitis virus belong to a family Flaviviridae. These viruses are transmitted to vertebrates by infected mosquitoes or ticks, producing diseases, which have a serious impact on global public health. Reverse genetics is a powerful tool for studying the viruses. Although infectious full-length clones have been obtained for multiple flaviviruses, their early-stage development had the difficulty because of the instability problem of the viral cDNA in E. coli. Several strategies have been developed to circumvent the problem of infectious clone instability. The current knowledge accumulated on reverse genetics system of flaviviruses and its application are summarized in this review.
Theoretical and experimental study of a quantized lattice configuration in a nearly unstable defect system (1989)

Theoretical lattice dynamics analysis and new optical experiments on KI:${\mathrm{Ag}}^{+}$ reveal a nearly unstable low-temperature defect-host configuration, whose population decreases dramatically with temperature, but whose dynamics are consistent with a temperature-independent harmonic model involving collective motion. This behavior is in marked contrast to the temperature-dependent evolution of the dynamics of ``soft-mode'' systems.
Commercial SATCOM communications protection: Commercial SATCOM resilience to jamming (2011)

Commercial satellite communications are occasionally targeted by jamming for political/ideological reasons or suffer the effects of accidental interference. Jamming is rare enough that it is generally considered a tolerable business risk. Traditionally the threat has not been preemptively mitigated with anti-jam technologies. Instead, instances of jamming are dealt with reactively. Specialized commercial services locate the jammer and negotiations are used to persuade the instigator to cease the jamming activity. Although commercial business decisions have not driven broad implementation of anti-jam technologies low risk features are available. The last decade has seen an evolution of a new suite of commercial satellite communication systems. Driven to maximize the service providers' return on investment the systems increase the number of subscribers served within the limited bandwidth resource for relatively small growth in capital expense. Key to the exponential gains in capacity are technology enhancements at all layers of the protocol stack. Although developed to optimize a business case these technologies provide features that inherently provide resilience to interference, increase link availability, and with reasonable modification may be enhanced further to increase the resilience to jamming. This paper identifies features of modern commercial satellite systems relevant to assuring communications in a contested environment.
