COMPARISON OF EULER-EULER AND EULER-LAGRANGE APPROACH IN NUMERICAL SIMULATION OF MULTIPHASE FLOW IN VENTILATION

This paper presents the results of multiphase flow numerical simulations in ventilation mill and mixing duct with louvers separator of Kostolac B power plant. Due to very low volume fraction of the secondary solid phase, that is well below 10%, simulations are performed using both the mixture model of the Euler-Euler approach and EulerLagrange approach of ANSYS FLUENT software package. The gas mixture distribution at the main and secondary burner feed ducts obtained by the Euler-Euler mixture model is in a good agreement with the experiment. But aforementioned model also gives the same distribution of the pulverized coal at the burners, leading to large differences between the calculations and measurements. Because of that the Euler-Lagrange approach with Discrete Phase Model (DPM) is used where the fluid phase is treated as a continuum, while the dispersed solid phase is solved by tracking a large number of particles through the calculated flow field, i.e. computing the particle trajectories at specified intervals during the fluid phase calculation. Much better agreement of the calculated and measured value of the pulverized coal distribution at the burners is obtained using DPM. The tracking particles of the dispersed phase enables obtaining the influence of the louvers. It is noticed, in the numerical simulation, that due to the narrow gaps between the louvers only a small fraction of the pulverized coal passes through the gaps. The louvers actually act as an obstacle. The DPM model should be used in obtaining accurate distribution of the pulverized coal at the burners.
Micellar solubilization of poorly water soluble drug using non ionic surfactant

An important property of micelles with particular significance in pharmacy is their ability to increase the solubility of poorly soluble drug in water, this increase their bioavailability. The micellar soulibilization is a powerful alternative for dissolving hydrophobic drugs in aqueous environments. In this work, the soulibilization of ketoconazole was studied in micellar solutions of two surfactant, namely Tween 80 and Brij 35. The solubility of ketoconazole increased linearly with increasing surfactant concentration, as a consequence of the association between the drug and the micelles. Critical micelle concentration of the non ionic surfactant (Tween 80 and Brij 35) in aqueous solution was determined by iodine probe method.
Severe recurrent hepatitis C after liver retransplantation for hepatitis C virus–related graft cirrhosis

An increase in the number of hepatitis C virus (HCV)‐infected transplant recipients at need for repeated liver transplantation is anticipated. To date, there is a certain reluctance to accept these patients because of an increased organ shortage, early reports suggesting a poor outcome, and uncertainty regarding the natural history of recurrent hepatitis C in the second graft. The aim of this study is to determine the outcome of patients undergoing retransplantation for HCV‐related graft cirrhosis. Of 49 transplant recipients with HCV‐related allograft cirrhosis, 31 patients developed decompensation with criteria for retransplantation. Thirteen patients were denied this option. Of the 18 patients accepted, 6 patients died while on the waiting list (5 patients died of graft cirrhosis at a median of 3.2 months of listing), and 12 patients have undergone retransplantation (median, 10 months since HCV cirrhosis). After retransplantation, 8 patients (67%) died at a median of 8 months, and 4 patients (33%) remain alive after 1.9 years of follow‐up. Causes and times of death from retransplantation were: surgical complications, n = 3 (perioperative period) HCV cirrhosis of the second graft, n = 2 (at 9 and 54 months) fibrosing cholestatic hepatitis, n = 1 (at 2 years) lymphoproliferative disorder, n = 1 (at 7 months) and endocarditis, n = 1 (at 3.5 years, with underlying cirrhosis). Of the 4 patients alive, fibrosis stages in the last biopsy specimens are stage 1 (n = 1), stage 3 (n = 1), and stage 4 or cirrhosis (n = 1; one patient has not undergone biopsy), despite antiviral therapy. The outcome of retransplantation for HCV cirrhosis of the first graft is very poor because of multiple complications. The severity of recurrent HCV disease in the second graft seems to be related to that observed in the first graft.
Tamper Detection in RFID-Enabled Supply Chains Using Fragile Watermarking

While mainstream RFID research has been focused on solving privacy issues, security in general and data tampering in specific is still an open question. This paper analyzes potential security threats especially data tampering in RFID-enabled supply chains and proposes solutions how these threats might be addressed using fragile watermarking technologies. We first survey RFID system and its security problems, and then explain the importance of fragile watermarking schemes for RFDD systems and possible applications using fragile watermarking to detect and locate any modification in RFID systems. Finally we suggest possible solutions using fragile watermarking for RFDD-enabled supply chain.

Design of RST controllers based on intelligent optimization algorithms

The Proportional Integral Derivative controller (PID) and the RST controller are the dominant controllers nowadays, since they have simple structure and perform well in most of control loops application. However, unlike PID the RST controller doesn't have direct tuning procedure. In this paper we present an approach for designing and tuning the RST controller by using intelligence optimization algorithms. Three algorithms namely (BSOA, DE and PSO) have been tested in tuning RST controller that controls an electrical DC motor that has been used as a benchmark. Simulation results show PSO tuned RST structure to be more robust and have high performance.

Pain and distress in advanced dementia: Choosing the right tools for the job

Objective: There is a concern that pain is under-recognized in dementia. However, there may be other causes of distress. We wished to evaluate the utility of a distress tool and a pain tool. Methods: Nursing home residents with advanced dementia were observed using pain (Pain Assessment in Advanced Dementia scale (PAINAD)) and distress (Disability Distress Assessment Tool (DisDAT)) assessment tools. Those in pain were treated. Reassessment occurred at one and three months. Results: From 79 participants, 13 were assessed as being in pain. Psychosocial factors explained the behaviour of a false positive group. Both tools showed a significant decrease in pain following intervention (p = 0.008). Behaviours were similar in both groups. Conclusions: Both tools are useful. However, the pain tool also picks up distress, which is not caused by pain. It could potentially lead to false ascriptions of pain. The distress tool picks up a broader array of signs, which may be useful both in practice and in research.
Halftoning-based self-embedding watermarking for image authentication and recovery

This paper presents a block-wise semi-fragile watermarking algorithm for image content authentication, with tamper region localization and recovery capability. A halftone image is generated by the error diffusion halftoning method and embedded using the Quantization Index Modulation (QIM) method in the Discrete Cosine Transform (DCT) domain of the original image. The proposed method is robust to JPEG compression, because the halftone image is embedded as a watermark sequence in the middle frequencies of the DCT coefficients using QIM. Also to improve the recovered image quality, Multilayer Perceptron neural network (MLP) is used in inverse halftoning process. Data in the tampered region is estimated with gray-scale data obtained from the MLP, using the embedded halftone as input. The experimental results show desirable performance of the proposed algorithm, such as watermark imperceptibility, robustness to JPEG compression, detection accuracy of tampered region and high quality of recovered image.
Emulating atmosphere-ocean and carbon cycle models with a simpler model, MAGICC6 – Part 2: Applications

Intercomparisons of coupled atmosphere-ocean general circulation models (AOGCMs) and carbon cycle models are important for galvanizing our current scientific knowledge to project future climate. Interpreting such intercomparisons faces major challenges, not least because different models have been forced with different sets of forcing agents. Here, we show how an emulation approach with MAGICC6 can address such problems. In a companion paper (Meinshausen et al., 2011a), we show how the lower complexity carbon cycle-climate model MAGICC6 can be calibrated to emulate, with considerable accuracy, globally aggregated characteristics of these more complex models. Building on that, we examine here the Coupled Model Intercomparison Project's Phase 3 results (CMIP3). If forcing agents missed by individual AOGCMs in CMIP3 are considered, this reduces ensemble average temperature change from pre-industrial times to 2100 under SRES A1B by 0.4 °C. Differences in the results from the 1980 to 1999 base period (as reported in IPCC AR4) to 2100 are negligible, however, although there are some differences in the trajectories over the 21st century. In a second part of this study, we consider the new RCP scenarios that are to be investigated under the forthcoming CMIP5 intercomparison for the IPCC Fifth Assessment Report. For the highest scenario, RCP8.5, relative to pre-industrial levels, we project a median warming of around 4.6 °C by 2100 and more than 7 °C by 2300. For the lowest RCP scenario, RCP3-PD, the corresponding warming is around 1.5 °C by 2100, decreasing to around 1.1 °C by 2300 based on our AOGCM and carbon cycle model emulations. Implied cumulative CO 2 emissions over the 21st century for RCP8.5 and RCP3-PD are 1881 GtC (1697 to 2034 GtC, 80% uncertainty range) and 381 GtC (334 to 488 GtC), when prescribing CO 2 concentrations and accounting for uncertainty in the carbon cycle. Lastly, we assess the reasons why a previous MAGICC version (4.2) used in IPCC AR4 gave roughly 10% larger warmings over the 21st century compared to the CMIP3 average. We find that forcing differences and the use of slightly too high climate sensitivities inferred from idealized high-forcing runs were the major reasons for this difference.
Optimal location and quantum of DG in a multi-feed system with varying LMPs

Amendment of Electricity market from vertically integrated environment to deregulated environment necessitates the consideration of locational marginal price (LMP) while evaluating the optimal location and quantum of DG in a distribution system. In this paper optimal location and quantum of DG are found considering varying load in the system, varying locational marginal prices of each feeder and optimal reconfiguration of the system. The solution of DG obtained for one snapshot of load and LMP may not be the same for other snapshot. It would thus be better to perform the analysis of DG placement considering the overall benefit achieved over the period of interest by optimally placing the DG in a given distribution system. Genetic algorithm is used to solve the DG placement problem based upon cumulative cost of power purchased by the system over a period of interest for varying loads and locational marginal prices. The proposed approach is applied to a multi-feed distribution system for three different cases of LMP and the results obtained are analyzed.
Estimates of global and regional smoking prevalence in 1995, by age and sex.

OBJECTIVES We calculated regional and sex- and age-specific smoking prevalence estimates worldwide in 1995. METHODS Sex-specific smoking prevalence data from studies in 139 countries and age distribution data from 7 studies were analyzed. RESULTS Globally, 29% of persons aged 15 years or older were regular smokers in 1995. Four fifths of the world's 1.1 billion smokers lived in low- or middle-income countries. East Asian countries accounted for a disproportionately high percentage (38%) of the world's smokers. Males accounted for four fifths of all smokers, and prevalence among males and females was highest among those aged 30 to 49 years (34%). CONCLUSIONS Future decades will see dramatic increases in tobacco-attributable deaths in low- and middle-income regions. Although much of this excess mortality can be prevented if smokers stop smoking, quitting remains rare in low- and middle-income countries.
Scene Flow-Based Environment 3D Digitalization for Mobile Robot Navigation

Abstract This paper presents an effective 3D digitalization technique to reconstruct an accurate and reliable 3D environment model from multi-view stereo for an environment-learning mobile robot. The novelty of this paper lies in the introduction of nonrigid motion analysis to stereo reconstruction routine. In our proposed scheme, reconstruction task is decoupled into two stages. Firstly, range depth of feature points is recovered and in turn is used for building a polygonal mesh and secondly, projection feedback on comparison views, which is generated on assumption of the established coarse mesh model, is carefully introduced to deform the primitive mesh model so as to improve its quality dramatically. The discrepancy of observation on comparison views and the corresponding predictive feedback is quantitatively evaluated by optical flow field and is employed to derive the corresponding scene flow vector field subsequently, which is then used for surface deformation. As optical flow vector field estimation outperforms traditional dense disparity for its inherent advantage of being robust to illumination change and being optimized and smoothed in global sense, the deformed surface can be improved in accuracy, which is validated by experimental results.
A low power monolithic AGC with automatic DC offset cancellation for direct conversion hybrid CDMA transceiver used in telemetering

The monolithic integration can be made possible with the advantages of direct conversion techniques. However, DC offset and flicker noise become critical to the system. In this paper we propose a wide tuning range AGC with an effective automatic DC offset cancellation. The proposed AGC is specifically designed for direct conversion hybrid CDMA system operating at 2.4 GHz used in telemetering applications. The AGC was fabricated using TSMC 0.35 um double poly process. The circuit achieves a 80 dB continuous gain tuning range, [-30 dB, 50 dB], with 40 dB dynamic range for differential output voltage set to 500 mV/sub pp/ and a THD better than 30 dBc. The AGC is powered by 3 V with 7 mW power consumption.
Robust face tracking based on bayesian probability

It is a tough task to robust track face in dynamic complex environments with an active camera. A tracking method based on Bayesian probability is proposed to real-time follow-up track moving face in dynamic complex environments. At first frontal face is detected using the Adaboost face detector based on Haar-like features, and is used to initialize the tracking module. Face color feature representation based on histogram is introduced. Face tracking is realized with the enhanced Camshift algorithm implemented in the color probability density distribution image (CPDDI). To consider and suppress disturbance from background, Bayesian probability is used to produce CPDDI. Experimental results show that the presented method is well suitable for tracking face with arbitrary pose in dynamic complex environments with an active camera. The method is computationally efficient and can run in real-time speed completely.
DNA Damage Induces p53-dependent Down-regulation of hCHK1*

The levels of the human checkpoint gene hCHK1 were measured in human cancer cells growing in vitro after treatment with the DNA damaging agent cis-dichlorodiammine platinum(II) (DDP). Treatment of human cancer cell lines with DDP induced a decrease in the hCHK1 protein levels starting 6 h after treatment, with a further decline at 24 and 48 h. A similar decrease in the levels of hCHK1 was found at the mRNA level by using Northern blot analysis. By using isogenic cell systems in which p53 was disrupted either by transfection with HPV-E6 or by targeted homologous recombination, we found that the DNA damage-induced down-regulation of hCHK1 was only observable in wild type p53-expressing cells, with only a minor decline in the hCHK1 levels observable 48 h after treatment in cells with disrupted p53. Similarly, treatment of mutant p53-expressing human cancer cell lines with DDP did not result in changes in the levels of hCHK1. The p53-dependent down-regulation of hCHK1 is likely to be at transcriptional levels, as suggested by the lack of down-regulation of the hCHK1 when transfected under the control of a heterologous viral promoter. In addition, p53 is able to down-regulate the luciferase activity under the control of the 5′ flanking region of the hCHK1 gene. The data suggest a strict link between p53 and hCHK1 governing the activation and repression of the G2 checkpoint in which both proteins participate.
Planktonic-Cell Yield of a Pseudomonad Biofilm

ABSTRACT Biofilm cells differ phenotypically from their free-floating counterparts. Differential growth rates in biofilms are often referred to, particularly in response to limited diffusion of oxygen and nutrients. We observed growth rates of attached Pseudomonas sp. strain CT07 cells that were notably higher than the maximum specific growth rate measured in batch culture. Despite dilution rates in continuous flow cells that exceeded the maximum planktonic specific growth rate by 58 times, sampling of the effluent revealed >109 cells ml−1, suggesting that biofilms function as a source of planktonic cells through high cell yield and detachment. Further investigation demonstrated considerable planktonic cell yield from biofilms as young as 6 h, indicating that detachment is not limited to established biofilms. These biofilm-detached cells were more sensitive to a commercial biocide than associated biofilm- and chemostat-cultivated populations, implying that detached biofilm cells exhibit a character that is distinct from that of attached and planktonic cell populations.
Investigation of Brillouin scattering in optical fibers for the generation of Millimeter waves

Stimulated Brillouin scattering (BS) in optical fibers is investigated for the generation of millimeter waves (mm-waves) for radio over fiber systems. Predictions of a numerical simulation are compared to experimental results, and both are in good agreement with each other. With the numerical simulation, the optimum parameter for the technique is calculated. It will be shown that the optimum length of the fiber for BS depends on the signal rather than on the pump power. This gives us the opportunity to adjust the parameters for any given fiber length. The advantages and limits of the proposed method for mm-wave generation are discussed.
A dual gene-silencing vector system for monocot and dicot plants.

Plant virus-based gene-silencing vectors have been extensively and successfully used to elucidate functional genomics in plants. However, only limited virus-induced gene-silencing (VIGS) vectors can be used in both monocot and dicot plants. Here, we established a dual gene-silencing vector system based on Bamboo mosaic virus (BaMV) and its satellite RNA (satBaMV). Both BaMV and satBaMV vectors could effectively silence endogenous genes in Nicotiana benthamiana and Brachypodium distachyon. The satBaMV vector could also silence the green fluorescent protein (GFP) transgene in GFP transgenic N. benthamiana. GFP transgenic plants co-agro-inoculated with BaMV and satBaMV vectors carrying sulphur and GFP genes, respectively, could simultaneously silence both genes. Moreover, the silenced plants could still survive with the silencing of genes essential for plant development such as heat-shock protein 90 (Hsp90) and Hsp70. In addition, the satBaMV- but not BaMV-based vector could enhance gene-silencing efficiency in newly emerging leaves of N. benthamiana deficient in RNA-dependant RNA polymerase 6. The dual gene-silencing vector system of BaMV and satBaMV provides a novel tool for comparative functional studies in monocot and dicot plants.
