Corncob‐to‐xylose residue (CCXR) derived porous biochar as an excellent adsorbent to remove organic dyes from wastewater (2018)

Biochar was prepared from corncob‐to‐xylose residue (CCXR) by KOH activation and anaerobic pyrolysis method. The effect of activation temperature on the microstructure of the biochar was studied. Results showed that the biochar prepared at 850°C (850NBC) possessed high specific surface area and exhibited excellent adsorption property. The maximum adsorption capacity of 2249 mg g −1 was obtained when 850NBC was used for treating methylene blue (MB) solution. Adsorption isotherm fittings revealed that Langmuir and Freundlich models were applicable to 850NBC adsorption process, and the adsorption process was limited by adsorption site and the biochar surface functional groups. Furthermore, 850NBC showed good adsorption property when it was used to treat the other organic dyes of Congo red (751 mg g −1 ), Orange II (735 mg g −1 ), Indigo carmine (662 mg g −1 ) and Methyl Orange (465 mg g −1 ). Biochar 850NBC also possessed an acceptable recyclability which maintained 68.7% absorption capacity after 6 cycles when it was used to treat MB solution. These results proposed that 850NBC is expected to be a promising potential adsorbent for treating organic dyes waste water.
Inhibition of Lipopolysaccharide-Induced iNOS and COX-2 Expression by Indole Alkaloid, 3-(Hydroxymethyl)-6,7-Dihydroindolo[2,3-a]Quinolizin-(12H)-one, via NF-κB Inactivation in RAW 264.7 Macrophages (2013)

3-(Hydroxymethyl)-6,7-dihydroindolo[2,3-a]quinolizin-(12H)-one is a bioactive indole alkaloid isolated from Nauclea officinalis, a plant species which is used as a traditional Chinese medicine. We investigated the anti-inflammatory properties of 3-(hydroxymethyl)-6,7-dihydroindolo[2,3-a]quinolizin-(12H)-one in RAW 264.7 murine macrophages. The results indicated that it inhibited the overproduction of NO and the release of TNF-α. Furthermore, this compound inhibited the expression of iNOS and COX-2 proteins, the enzymatic activity of iNOS, and the translocation of NF-κB to the nucleus induced by LPS. Therefore, we suggested that the effect of 3-(hydroxymethyl)-6,7-dihydroindolo[2,3-a]quinolizin-(12H)-one-mediated inhibition of the expression of LPS-induced iNOS and COX-2 genes is due to the suppression of NF-κB activation in the transcriptional level.
Fatigue Behavior and Nondestructive Evaluation of Full-Scale FRP Honeycomb Bridge Specimen (2006)

An experimental investigation was performed to assess the projected fatigue performance of a fiber-reinforced polymer honeycomb bridge that has recently been completed in Troupsburg, N.Y. The laboratory specimen was representative of a 305-mm-wide strip of the completed bridge. The specimen was first subjected to fatigue loading. Load, displacement, and strain were measured every 25,000 cycles. The data indicated minimum signs of degradation after 2 million cycles of fatigue loading, as reflected in slightly increased values of vertical deflection and strain at midspan. After completion of the fatigue loading, the specimen was evaluated with acoustic emission. Load was statically applied and increased incrementally until failure occurred at a load level exceeding 16 times the fatigue level loading. The results of the static testing also indicated that only minor damage occurred due to fatigue. Field load testing of the actual bridge has been completed by the New York State Department of Transportation, and the results are discussed as they pertain to the fatigue and static load testing programs described.
Pulse sharpening and soliton generation with nonlinear transmission lines for producing RF bursts (2010)

Nonlinear transmission lines (NLTL) are being designed and built to extend the range of available Ultra-Wide Band (UWB) and High Power RF pulse generation technology, especially in the area of high repetition rate microwave burst generation. The NLTL approach to UWB and RF generation eliminates the need for the electron beam, vacuum system, and magnets required in conventional high power microwave (HPM) sources. Furthermore, the novel waveforms of NLTL generated pulses promise to offer a degree of frequency diversity unseen in current electron beam-driven HPM sources. UWB pulses are obtained using the wave front steepening properties of a transmission line with an amplitude dependent phase velocity. Ferrite loaded NLTLs have a phase velocity that increases with amplitude, so the pulse's voltage peak travels faster than the trough until the rise time is limited by dissipation. The addition of dispersion, which occurs in lumped periodic structures, can lead to the generation of a soliton, or solitary wave, and in some cases a group of solitons, where the dispersion replaces the dissipation as the balancing mechanism of the wave front steepening. Soliton bursts can be extracted from the line and delivered to a load as high power RF energy. A multi-stage system that consists of a pulsed power modulator for converting DC power into a high-voltage nanosecond pulse, a semi-continuous NLTL composed of biased ferrite beads for creating a fast rise-time UWB pulse, and a dispersive, lumped element NLTL that converts the UWB pulses into bursts of RF energy is discussed.

A method for assessment ofHelicobacter pylorigenotype using stool specimens (2009)

Helicobacter pylori infection has been regarded as a major factor associated with the development of gastric diseases. The characterization of infected H. pylori in asymptomatic individuals is important for the prediction of the onset of such diseases. However, because of the difficulty in obtaining gastric biopsy samples, H. pylori in healthy subjects have not been studied sufficiently. Therefore, we tested a noninvasive method for the characterization of H. pylori using stool specimens. This method involved H. pylori antigen detection in stool specimens by immunochromatography; confirmation of H. pylori DNA by real-time PCR that involved the detection of its 16S rRNA gene in the DNA extracted from stool specimens; and nested PCR with genotype-specific primer pairs. A total of 80 samples obtained from asymptomatic subjects were assessed using this method. The results showed that the prevalence of H. pylori in asymptomatic Japanese individuals was 37.5%. The detection rate of the virulence factor gene cagA was 18.8%. Furthermore, all the detected cagA belonged to the highly virulent East-Asian type. These data suggest that the method used in this study is valuable for studying the molecular epidemiology of H. pylori infection in asymptomatic people.
Should a Low-Fat, High-Carbohydrate Diet Be Recommended for Everyone? (1997)

Low-fat diets are often advocated for weight reduction and to lower the risk of coronary heart disease and certain forms of cancer. However, there is no universal agreement about the value of low-fat diets. In this Clinical Debate, Connor and Connor argue in favor of the public health benefits of low-fat diets, whereas Katan, Grundy, and Willett present a different point of view.

Exploitation of Run-TIme Partial Reconfiguration for Dynamic Power Management in Xilinx Spartan III-based Systems (2007)

Reconfigurable architectures such as FPGAs are a key technology for implementing self-adaptive and flexible systems, since the possibility for dynamic and partial hardware reconfiguration offers a higher degree of freedom in the resource allocation. However, for many applications, modern reconfigurable architectures cause too high power consumption. For this reason, FPGAs are typically used in highly computational applications where the possibility for performing parallel calculations can be exploited to achieve decreased power consumption as compared to a microcontroller based solution. In order to enable the usage of FPGAs even in low- power applications, techniques for adapting the power consumption according to the work load must be investigated. One novel approach would be to exploit the possibility for dynamic reconfiguration of the FPGA for this purpose. This paper presents the realization of dynamic clock scaling in a Xilinx Spartan 3 based system by performing dynamic and partial reconfiguration of the fixed Digital Clock Manager (DCM) core configuration.

Red de coordinación para el seguimiento y la implantación de nuevas actividades basadas en las TICs en las asignaturas de Genética de los Grados en Biología y Ciencias del Mar (2019)

El aprendizaje en las asignaturas de Genética exige la comprensión de conceptos complejos y una elevada capacidad de deducción y razonamiento, por lo que les resulta difícil a alumnos acostumbrados a asignaturas mayoritariamente descriptivas. Por este motivo, desde el Área de Genética hemos tratado siempre de emplear actividades que sirvan tanto a los estudiantes de entrenamiento para adquirir estas competencias como a los docentes para evaluar su adquisición, proporcionando un marco para practicar el razonamiento y la deducción. En la anterior Red, implantamos el uso de TICs en la evaluación de las actividades prácticas de nuestras asignaturas, con resultados bastante satisfactorios con respecto al desarrollo de la actividad y a las mejoras en la evaluación de los alumnos. En este trabajo, además de evaluar la implantación de esas mismas TICs en el contexto de grupos con mayor masificación (grupos de teoría), planteamos la introducción de una nueva metodología en el contexto de la asignatura de Genética, que implica combinar una actividad ya instaurada como clásica en nuestras asignaturas (la resolución de problemas en grupo) con la evaluación por iguales, con el fin de potenciar el grado de implicación de los alumnos en su propio aprendizaje y evaluación.
Spontaneous dyskinesia and parkinsonism in never-medicated, chronically ill patients with schizophrenia: 18-month follow-up (2002)

Spontaneous dyskinesia and parkinsonism fluctuate over time. The former was found on at least one occasion in the majority of patients. It is an integral part of the schizophrenic disease process.
Measuring Sustainability: How Traffic Incident Management through Intelligent Transportation Systems has Greater Energy and Environmental Benefits than Common Construction-Phase Strategies for “Green” Roadways (2011)

ABSTRACT The research presented in this paper compares the direct emissions and fuel consumption savings of five different strategies for greener roads. Specifically, savings from an incident management strategy using an Intelligent Transportation Systems (ITS) application, traffic cameras, is compared to savings from strategies focused on the construction phase including; using regionally provided materials, reducing fossil fuel use, reusing pavement, and using warm-mix asphalt. The comparison used lifecycle assessment to evaluate a 10-mile segment of a key urban interstate in South Carolina. The results revealed that within the first year of operations, implementing the selected ITS strategy would provide a fuel savings that is over 3 times greater than the combined savings that could be realized by implementing all 4 construction-phase strategies together. For an 8-year repaving schedule, the ITS strategy provides fuel savings over 30 times larger than all the construction phase strategies combined, and reduces carbon-dioxide emissions over 5 times more than any one of the construction-phase strategies. The article highlights ITS's effectiveness as a sustainability tool by comparing emissions and fuel use reductions to sustainable construction strategies. These results suggest that policies and rating systems for more sustainable roads should weigh ITS strategies considerably more than individual construction-phase strategies. The results also highlight the need for transportation policy to evaluate the benefits of all potential sustainable strategies to encourage implementation of the most effective ones.
<title>Helmet-mounted display research activity on the NRC Bell 205 airborne simulator</title> (1997)

The National Research Council (NRC) of Canada, in conjunction with the Canadian Department of National Defence, is investigating the use of helmet-mounted displays as an aid in improving pilot situational awareness in all- weather search and rescue helicopter operations. For over 30 years, the NRC Bell 205 Airborne Simulator has been an integral part of valuable research programs. Equipped with a full authority fly-by-wire control systems, the Bell 205 has variable stability characteristics, which makes the airborne simulator the ideal platform for the integrated flight testing of helmet-mounted displays in a simulated operational environment. This paper will describe the test facility in detail, including a description of the airborne simulator, the fiber-optic helmet-mounted display hardware, the camera system, the head tracking system, and the sensor platform. In addition, the paper will provide a complete description of the symbology overlaid on the camera image that was developed for use with the helmet mounted display. The paper will conclude with the description of a planned preliminary handling-qualities investigation into the effects of using helmet-mounted displays on the pilot's workload and performance while performing standard maneuvers.
Fluorescence Emission and Polarization for Analyzing Binding of Ruthenium Metalloglycocluster to Lectin and Tetanus Toxin C-Fragment (2009)

We have designed and synthesized ruthenium complexes bearing clustered galactose Ru(bpy-2Gal)(3) and glucose Ru(bpy-2Glc)(3). Changes in fluorescence emission (FE) and fluorescence polarization (FP) of the metalloglycoclusters were measured by adding each lectin (peanut agglutinin (PNA), Ricinus communis agglutinin 120 (RCA), concanavalin A (ConA), or wheat germ agglutinin (WGA)) or tetanus toxin c-fragment (TCF). Following the addition of PNA and ConA, the FE spectra of Ru(bpy-2Gal)(3) and Ru(bpy-2Glc)(3) showed new emission peaks, respectively. In addition, Ru(bpy-2Gal)(3) and Ru(bpy-2Glc)(3) exclusively increased the FP values by addition of PNA and ConA. Since other combinations of the metalloglycoclusters and lectin caused little change, specific bindings of galactose to PNA and glucose to ConA were confirmed by the FE and FP measurement. From the FP analyses, the dissociation constants (K(d)) of Ru(bpy-2Gal)(3) to PNA and Ru(bpy-2Glc)(3) to ConA were calculated to be ca. 6.1 x 10(-6) M and 1.8 x 10(-5) M. Furthermore, the FP analyses proved specific binding of Ru(bpy-2Gal)(3) to TCF.
Ion Motion Synchronization in an Ion-Trap Resonator (2001)

Using a new type of ion trap, we demonstrate that the length of a packet of charged particles oscillating between two electrostatic mirrors will remain constant under special conditions. The effect can be understood in terms of phase synchronization, where, in a rather counterintuitive way, the repulsive Coulomb interaction between the ions actually holds the packet together. Application of this effect for mass spectrometry is discussed.
Heterozygosity for genes influencing a quantitative trait (2002)

Choosing families to sample for a quantitative trait locus mapping experiment is a critical component of experimental design because only heterozygous families contribute information to the analysis. Additive genetic variance of a paternal half-sib family can be partitioned into two parts: a variance component of maternal source that is constant across different families and a variance component of paternal source that is defined as an index of heterozygosity of a sire. This index is shown to be an upper limit of variance among marker genotypes of a half-sib family and can be used to identify highly heterozygous sires, thus improving the power of detecting QTL in detection studies. Simulated progeny phenotypic data were used to estimate sire's heterozygosity index via an ANOVA method, and accuracy of the estimation was evaluated with the correlation coefficient between the true and estimated index summarized both as the correlation and by the correct ranking of results as measured by the ratio of the true average heterozygosity index of experimentally selected parents to average heterozygosity of all sires. Positive but small correlation can be achieved in the estimation of a sire's heterozygosity when based on the daughters' phenotypic data, and accuracy was improved when progeny-tested sons were used to estimate their grandsire's heterozygosity index, depending on the genetic model of a trait and the size and structure of families.
A 1.6GB/s DDR2 128Mb chain FeRAM with scalable octal bitline and sensing schemes (2009)

An application that takes advantage of FeRAM characteristics is replacing current DRAM, which then becomes high-performance nonvolatile RAM cache. This improves system performance for many kinds of computer systems, including mobile PCs, cellular phones, digital video products, and storage systems such as SSDs. However, the highest capacity in nonvolatile RAMs that allow frequent cache reads and writes is limited to 64 Mb. The maximum read bandwidth is limited to 400 Mb/s and the write bandwidth is limited to 200 Mb/s in nonvolatile memories reported to date. The FeRAm was demonstrated in 4M 0.13 mum CMOS. A serious problem with FeRAM scaling is cell-signal degradation due to ferroelectric capacitor scaling. The circuit diagram and device feature are also summarizes.
Impact of environmental control costs on an indirect coal liquefaction process (1981)

This report examines the effect on product price of three different scenarios for the control of emissions to the environment by a conceptual, commercial indirect coal liquefaction facility. The plant design utilizes Lurgi dry-ash gasifiers operating on western, subbituminous coal to provide synthesis gas for low-pressure methanol synthesis and subsequent conversion of the methanol to gasoline. Levels of emission control, which are based as much as possible on existing regulations for analogous processes, range from minimal control to more stringent control than that currently in effect. The use of several emission control options and the reduction of plant size are also examined in regard to their effects on product price. Environmental control to current levels would account for 12% of the product price for the facility assumed here. More stringent emission standards would produce an additional 3% increase. Reducing plant size would also raise product price. Two unpredictable factors having the greatest impacts on product price, however, are inflation and the method of financing. It should be noted that emisson control requirements could be postulated which would substantially change the assumed plant design and, consequently, the assumed service factor and the calculated product price.
Superposition MIMO Coding for the Broadcast of Layered Sources (2011)

We propose superposition multiple-input multiple-output (MIMO) coding for the transmission of unequally important sources in a point-to-multipoint system. First, a tradeoff between Alamouti code and spatial multiplexing (V-BLAST) is analyzed in terms of the average bit error rate (BER), where the maximum data rates of both MIMO schemes are set to be equal. The results show that for a given target bit error rate, Alamouti code is preferable for a low data rate, and spatial multiplexing is preferable for a high data rate. For layered sources such as scalable video, the more important component typically has lower data rate than does the less important component. Based on these, we construct a superposition MIMO scheme where two different MIMO techniques are hierarchically combined such that important data is Alamouti coded, less important data is spatially multiplexed, and then two unequally important data symbols are superposed.
Circuit-wise buffer insertion and gate sizing algorithm with scalability (2008)

Most existing buffer insertion algorithms, such as van Ginneken's algorithm, consider individual nets and therefore often result in high buffer cost due to lack a global view. Thus, circuit-wise buffering is necessary to reduce buffer cost. Recently, some circuit-wise buffering algorithms are proposed. However, these algorithms are based on heuristics which are not scalable in handling large circuits.
Micro fabrication of microlens arrays by micro dispensing (2009)

Abstract In this study, master of the microlens arrays is fabricated using micro dispensing technology, and then electroforming technology is employed to replicate the Ni mold insert of the microlens arrays. Finally, micro hot embossing is performed to replicate the molded microlens arrays from the Ni mold insert. The resin material is used as the dispensing material, which is dropped on a glass substrate. The resin is exposed to a 380 W halogen light. It becomes convex under surface tension on the glass substrate. A master for the microlens arrays is then obtained. A 150‐nm‐thick copper layer is sputtered on the master as an electrically conducting layer. The electroforming method replicates the Ni mold insert from the master of the microlens arrays. Finally, micro hot embossing is adopted to replicate the molded microlens arrays. The micro hot embossing experiment employs optical films of polymethylmethacrylate (PMMA) and polycarbonate (PC). The processing parameters of micro hot embossing are processing temperature, embossing pressure, embossing time, and de‐molding temperature. Taguchi's method is applied to optimize the processing parameters of micro hot embossing for molded microlens arrays. An optical microscope and a surface profiler are utilized to measure the surface profile of the master, the Ni mold insert and the molded microlens arrays. AFM is employed to measure the surface roughness of the master, the Ni mold insert and the molded microlens arrays. The sag height and focal length are determined to elucidate the optical characteristics of the molded microlens arrays. Copyright © 2009 John &amp; Sons, Ltd.
