Efficient strategy for low nox combustor design in the spatial domain using multi-fidelity solutions

Gas turbine combustor designers now routinely use high-fidelity reactive computational fluid dynamics (CFD) analyses to gain valuable insight into the complex reactive flow-field and pollutant formation process. But, a large number of such computationally expensive CFD analyses are generally required to arrive at an acceptable combustor configuration. Therefore, given the practical limits on available computational resources and time, traditional combustor design methodologies using only high-fidelity CFD analyses need further improvement. To address this, a combustor design strategy using multifidelity co-Kriging response surface model (RSM) is developed and applied for the design of a two-dimensional test combustor problem in the spatial domain using steady-state Reynolds-averaged Navier Stokes (RANS) formulation. The design and optimization problem is set-up for two geometric variables and a single-objective, NOx concentration, as it is of current interest to the combustor design community. The developed multi-fidelity strategy is also assessed for performance against high-fidelity Kriging RSM strategy. This study demonstrates that the multi-fidelity design strategy can obtain good designs with up to ten times less effort than a full grid sampling search plan. However, the multi-fidelity co-Kriging strategy does not outperform the high-fidelity Kriging strategy for the given spatial domain problem. © 2013 ASME
Similar Gene Regulation Patterns for Growth Inhibition of Cancer Cells by RP215 or Anti-Antigen Receptors

RP215 is a monoclonal antibody generated against a carbohydrate-associated epitope of glycoproteins designated as CA215, which consists mainly of immunoglobulin superfamily proteins expressed by cancer cells including antigen receptors such as immunoglobulins and T-cell receptors. Since RP215 was shown to induce apoptosis and inhibit tumor growth in nude mouse models, the effects of RP215 and antibodies against antigen receptors on the gene regulations of cultured OC-3-VGH ovarian and C-33A cervical cancer cells were investigated through semi-quantitative RT-PCR. For both cell lines, RP215 and anti-antigen receptors were found to regulate similarly and consistently a number of genes including NFκB-1, IgG, P21, Cyclin D1, ribosomal P1 and c-fos with only exceptions for EGFR and ribosomal P0. Among toll-like receptor genes (TLR-2, -3, -4, -6, -7 and -9), differential levels of gene expressions in different cancer cell lines were observed. RP215 and anti-antigen receptors were found to up-regulate TLR-2 and/or TLR-3, whereas those of TLR-4 and TLR-9 were down regulated for both cancer cells. Based on these preliminary observations, it can be proposed that apoptosis of the two cancer cell lines was induced similarly by RP215 and anti-antigen receptors through consistent regulations of the same groups of genes. The innate immunity of cancer cells can also be affected by any of these antibodies through unidirectional regulations of certain toll-like receptors. Excellent correlations were obtained (R2=0.90-0.94) in terms of gene regulation patterns affected by any of these binding ligands. Therefore, the anti-cancer therapy of RP215 Mab may be, in part related to the surface bound antigen receptors and/or toll-like receptors in the innate immunity system, all of which may be involved in the growth and survival of cancer cells.
Potential role of scallops Argopecten irradians in deposition of particulate nutrient and trace elements in a eutrophic estuary, northern China

Anthropogenic inputs of nutrients and trace elements have globally significant impacts on coastal waters. In order to evaluate the effect of the filter-feeding bay scallop Argopecten irradians on benthic-pelagic coupling in a eutrophic estuary (Laizhou Bay), biodeposition of total suspended materials, particulate nutrient (C, N, P) and trace elements (Cu, Zn, Pb, Cr, Cd, Hg, As) were determined using modified sediment traps during autumn 2013. Results showed that biodeposition rates of the bay scallops were rather high compared with those reported for other bivalves. The allometric relationship between the biodeposition rate (BDR; g ind.(-1) d(-1)) and soft tissue dry weight (W; g ind.(-1)) was modeled (BDR = aW(b)) with the value of a being 1.24 in September and dropping to 0.96 in October. The biodeposition contributed to the enrichment of organic matter, C and N in the local sediment. Trace element concentrations in the scallop biodeposits were significantly higher than those of the natural surrounding sediments, especially during the months of October and November. A. irradians significantly increases the mass fluxes from the water column to the bottom, with estimated 1140 tonnes of total suspended material being deposited to the seabed each day in the culture zone. Results also suggest that biotransformation and biodeposition by such efficient filter-feeders may play a pivotal role in the fate and transportation of particulate nutrient and trace elements in aquatic ecosystems. In coastal waters and estuaries subject to anthropogenic inputs, suspended bivalve aquaculture could be environmentally advantageous via intense filtering and biodeposition, potentially mitigating eutrophication trace and element pressures.
Rethiking group therapy for anorexic patients

This paper presents an approach to working with groups of anorexic patients via decoding of primitive concrete language. Certain assumptions about treating anorexics with group therapy have been held up as reasons for not using this mode of therapy. The characteristics of patients with anorexia nervosa are that they remain withdrawn despite restoration of body weight, anxious, rigid, egocentric, preoccupied with body weight and food and have extreme difficulty in identifying and expressing feeling. Thus the patients are likely to be silent, or so preoccupied with food that this may be the sole topic of discussion. Using the traditional methods of psychoanalysis and group analysis, little success has been reported with this patient group. It is also difficult to construe the characteristics described above in terms of traditional psychoanalytic concepts. Bruch (1973) and Selvini-Palazzoli (1974) described early disturbances in the mother-infant relationship, which contribute to the development of the personality structure associated with anorexia nervosa. They suggest that the defective ego must be recognised and strengthened in psychotherapy in a way similar to the approaches used with borderline, narcissistic or schizophrenic patients. This paper suggests that, due to the changes in thought and language exhibited by this patient group, essential early communication and language skills can be enhanced by group work. Attention to these tasks by the group conductor or therapist forms part of the building blocks on which later, overtly language-based therapies, depend (Lacan, 1998). Most in-patient facilities are based around group activities and we must assume that there are sound therapeutic reasons for doing so other than economic viability. Most of these groups are not talking groups but are task orientated. The question might be, are these tasks therapeutic in their own right? Do cooking groups instil a knowledge of what constitutes appropriate amounts of food in an appropriate context, or making a collage of female figures from magazines improve perception of body image or is there an occluded task, related to early communication skills?
Locating Longitudinal Respondents After a 50-Year Hiatus

Abstract Many longitudinal and follow-up studies face a common challenge: locating study participants. This study examines the extent to which a geographically dispersed subsample of participants can be relocated after 37 to 51 years of noncontact. Relying mostly on commercially available databases and administrative records, the 2011-12 Project Talent Follow-up Pilot Study (PTPS12) located nearly 85 percent of the original sample members, many of whom had not participated in the study since 1960. This study uses data collected in the base year to examine which subpopulations were the hardest to find after this extended hiatus. The results indicate that females were located at significantly lower rates than males. As expected, sample members with lower cognitive abilities were among the hardest-to-reach subpopulations. We next evaluate the extent to which biases introduced during the tracking phase can be minimized by using the multivariate chi-square automatic interaction detection (CHAID) technique to calculate tracking loss adjustments. Unlike a 1995 study that found that these adjustments reduced statistical biases among its sample of located females, our results suggest that statistical adjustments were not as effective in PTPS12, where many participants had not been contacted in nearly 50 years and the tracking rates varied so greatly across subgroups.
Embedment of metal nanoparticles in GaAs and Si for plasmonic absorption enhancement in intermediate band solar cells

The high near-field enhancement occurring in the vicinity of metallic nanoparticles (MNPs) sustaining surface plasmons can only be fully exploited in photovoltaic devices if the MNPs are placed inside their semiconducting material, in the photoactive region. In this work an experimental procedure is studied to embed MNPs in gallium arsenide (GaAs) and silicon (Si), which can be applied to other semiconductor host materials. The approach consists in spin-coating colloidal MNPs dispersed in solution onto the substrate surface. Then a capping layer of the same material as the substrate is deposited on top to embed the MNPs in the semiconductor. The extinction spectra of silver (Ag) and gold (Au) MNPs embedded in GaAs and Si is modeled with Mie theory for comparison with optical measurements. This contribution constitutes the initial step towards the realization of quantum-dot intermediate band solar cells (QD-IBSC) with MNP
Updating the Economic Impacts of the High/Scope Perry Preschool Program

This article derives an updated cost-benefit ratio for the High/Scope Perry Preschool Program, an intensive preschool intervention delivered during the 1960s to at-risk children in Ypsilanti, Michigan. Because children were randomly assigned to the program or a control group, differences in outcomes are probably attributable to program status. Data on outcome differences is now available on participants as they reached the age of 40; outcomes include educational attainment, earnings, criminal activity, and welfare receipt. These outcomes are rendered in money terms and compared to the costs of delivering the program to calculate the net present value of the program both for participants and for society. The data show strong advantages for the treatment group in terms of higher lifetime earnings and lower criminal activity. For the general public, gains in tax revenues, lower expenditures on criminal justice, lower victim costs, and lower welfare payments easily outweigh program costs. At a 3% discount rate the program repays $12.90 for every $1 invested from the perspective of the general public; with a 7% discount rate, the repayment per dollar is $5.67. Returns are even higher if the total benefits—both public and private—are counted. However, there are strong differences by gender: a large proportion of the gains from the program come from lower criminal activity rates by the treatment group, almost all of which is undertaken by the males in the sample. The implications of these findings for public policy on early childhood education are considered.
Scalable uniform construction of highly conditional quantum gates

We present a scalable uniform technique for the construction of highly conditional multiply-controlled-not quantum gates of trapped ion qubits, such as the Toffoli gate, without using ancilla states and circuits of an exorbitant number of concatenated one- and two-qubit gates. Apart from the initial dressing of the internal qubit states with vibrational phonons and the final restoration of the phonon ground state, our technique requires the application of just a single composite pulse on the target qubit and is applicable both in and outside the Lamb-Dicke regime. We design special narrowband composite pulses, which suppress all transitions but the conditional transition of the target qubit; moreover, these composite pulses significantly improve the spatial addressing selectivity.
White-Coat Hypertension and Carotid Artery AtherosclerosisA Matching Study

Methods: Community residents 40 to 70 years of age and not receiving any cardiovascular medications were recruited to participate in a study of cardiovascular risk factors. On the basis of clinic and daytime ambulatory BP and a threshold criterion of 140/90 mm Hg, subjects were classified as having persistent hypertension, whitecoat hypertension, or persistent normotension. One-toone matching was conducted in male participants on the basis of race and BP. Subjects with persistent hypertension and white-coat hypertension were matched on clinic BP, and those with white-coat hypertension and normotension were matched on daytime ambulatory BP. Results: The 3 matched groups of men (n=40 in each group) were similar in age, smoking status, and fasting glucose and lipid levels. Compared with the normotensive subjects, subjects with either persistent or whitecoat hypertension had greater mean body mass index, waist-hip ratio, and fasting insulin concentration. On the basis of standardized duplex ultrasound examination of the carotid arteries, mean maximal intimal-medial thickness and plaque index in subjects with white-coat hypertension were greater than among normotensive subjects and equal to that of the subjects with persistent hypertension.
Relationships between gas‐liquid interfacial surface area, liquid saturation, and light transmission in variably saturated porous media

Liquid saturation and gas‐liquid interfacial area are important parameters for evaluating the transport and fate of contaminants in unsaturated subsurface environments. Recent findings indicate that interfacial surface area controls the relative degree of transmitted light in laboratory systems containing translucent porous media. Equations are derived to estimate the specific gas‐liquid interfacial area from the area under the primary‐drainage branch of the Seff‐h characteristic curve as parameterized using common water retention functions. The total area under the curve provides the maximum available specific gas‐liquid interfacial area available at residual saturation, which can be incorporated into the relationship to determine the gas‐liquid interfacial area at intermediate degrees of saturation via light transmission. Experimental results, and analysis of external data sets, support these findings. Closed‐form relationships are presented as enhancements to a recent method for determination of liquid saturations above residual using light transmission. A physically based model is developed and tested for the quantification of liquid contents below residual saturation.
Pressure drop in aqueous surfactant solution flow through pipes in SIS structure degradation zone

The paper describes chemical and rheologic properties of solutions of polymer additives and cationic surfactants while they flow though pipes in a laminar and turbulent zone and their influence on drag reduction. Surface active additives or aqueous solutions of surfactants form rod-like micelles, associated into an intermolecular SIS structure that absorbs the turbulence energy at the passage through a pipe, thus influencing the reduction in pressure drop or drag reduction. The influence of the velocity of aqueous solution of surface active additives is analysed in pipes in the Re number range, where high shear stress leads to a degradation of the surfactant intermolecular SIS structure and the drag reduction effect disappears. The pressure drop and drag reduction rate diagrams as functions of aqueous surfactant solution flow velocity and Re number are based on computer calculations.
International Companies' Perception of Digital Marketing Strategies and Their Implementation

The purpose of the study was to investigate how well international companies have adapted to the digital revolution and find the reasons behind implementing or neglecting certain digital marketing strategies. The study also looked at the impact such strategies have on the brand. Both quantitative and qualitative research methods were applied during this study. A web asset audit developed by The Duffy Agency was the foundation to assess the web presence of 12 international companies. Semi-structured interviews with 5 marketing employees were used to gain insight to the reasons behind their decisions. The findings show that in general companies are on their way to adapting to the digital revolution. They understand the importance of the web for business. Findings indicated that companies with well experienced employees and management with the right attitude adapted better. The study should be of use for both practitioners and academics. Applying a practical framework in academic research gives academics a broader understanding of how the business world is adapting to the digital revolution. Practitioners may benefit from the findings which show how a strong web presence can influence consumers’ perceptions of the brand and why it’s important for businesses’ to be present in the digital world
Phenotypic diversity of soybean (Glycine max (L.) Merr.)accessions in the Philippines for utilization

An increasing trend of soybean production and consumption has been seen in the Philippines. To assess the potential of the soybean germplasm for utilization, diversity of the Philippine soybean collection was established. High diversity was marked on 17 out of 29 qualitative characters, which include plant growth habit, leaf blistering and flower standard color. Phenotypic diversity indices (H’) of 92 soybean accessions averaged at 0.62. This aside, traits identical to a variety of soybean with superior characters were all present in the soybean germplasm collection. Using simple matching similarity coefficient, cluster analysis separated the different accessions into 12 distinct clusters at 62% similarity. Categorical Principal Component Analysis (CATPCA) showed that two independent components accounted for 35.36% of the total variation of the qualitative morphological characters. Factor loadings for each component showed the morphological characters, such as pubescence color, flower wing color, and seed coat color, that were contributing to the high projections in the two principal components. Accessions with vigorous seedlings were also observed. With the marked trait diversity, the soybean collection could be potentially used directly and for breeding purposes. Consequently, to uncover further the potential of our genetic resources at hand, the remaining germplasm accessions at NPGRL should be characterized and evaluated.
Determination of Dicarboxylic Acids and Levoglucosan in Fine Particles in the Kanto Plain, Japan, for Source Apportionment of Organic Aerosols

Fine particles were collected at a suburban site in the inland Kanto plain, Japan, in the spring and winter of 2007, and the summer of 2008. Organic carbon (OC), water-soluble organic carbon (WSOC), elemental carbon (EC), inorganic ions, and water-soluble organic compounds (dicarboxylic acids and levoglucosan) were analyzed. The WSOC/OC ratio was the highest in summer, followed by in spring, suggesting that organic aerosols were influenced by aging. The concentrations of total diacids (C2–C9) in spring and summer were higher than in winter. In each season, WSOC showed a strong positive correlation with the total diacids. Levoglucosan, which is recognized as a biomass burning tracer, was observed in a considerably higher concentration in winter than in spring or summer. In winter, WSOC also showed a strong positive correlation with levoglucosan. These results indicate that secondary formation is important as a source of WSOC and OC especially in the warm seasons, although emissions from biomass burning also contribute to WSOC in winter. By using the combination of source profile for biomass burning emission and EC tracer method, OC derived from biomass combustion in winter was calculated to be 47% of OC and OC derived from secondary formation in summer was calculated to be 75% of OC.
Effect of dietary moringa (Moringa oleifera) and rosemary (Rosmarinus officinalis) leaves or their mixture on productive performance, carcass characteristics and antioxidant enzymes of rabbits reared under heat stress conditions

Sixty growing New Zealand White (NZW) male rabbits aged six weeks, weighed 750.0±5g were used in a feeding experiment lasted 9 weeks. Rabbits were housed in controlled-climatic conditions at a mean ambient temperature 33.1°C and relative humidity 43% to keep rabbits under heat stress conditions. The rabbits were randomly distributed to four equal groups (five replicates each). The 1 st group fed the control diet (R1), R2 group fed diet supplemented with 1% moringa leaves, R3 group fed diet supplemented with 1% rosemary leaves, while R4 group fed diet supplemented with a mixture of moringa and rosemary leaves of 0.5% each. Diets and water were provided ad-libitum over nine weeks. The results revealed that live body weight, average daily gain and feed conversion ratio were significantly improved with R4 and R2 diets, while daily feed intake was not affected among groups. Apparent digestibility of crude fiber and ether extract were increased (p≤0.05) with R2 diet. Nitrogen balance was positive for all groups, however improvement (p≤0.05) was detected with R2 than control. Carcass characteristics were not affected among experimental groups. Hemo-lysatic catalase, glutathione peroxidase and super-oxide dismutase levels were increased (p≤0.01) with supplemented diets, while malondialdehyde was obviously decreased in the experimental groups compared with the control. It could be concluded that, supplementing diets with 1% moringa dry leaves or mixture of moringa leaves and rosemary leaves by 0.5+0.5% can be used to improve growth performance, nutrient digestibility and antioxidant status of rabbits reared under heat stress conditions.
Data of Ethnomedicinal Plants in Wazirabad, District Gujranwala, Punjab, Pakistan

Plants are vast natural sources significant organic and inorganic ethnomedicinal metabolic components that are free from side effects and are being used as probes and remedious agents since ancient times for local remedies. This paper documents the randomly sampled data of roots, leaves, seeds as well as whole plants of 31 ethnomedicinal plants of almost 21 families majorly Apiaceae, Fabaceae, Moraceae, Solanaceae and Rhamnaceae family used by local medicine men by conducting their unstructured interviews including open ended questions relevant to flora of Wazirabad, District Gujranwala, Punjab, Pakistan. This random sampling of different families of plants in particular climatic conditions can attract the phytochemists towards this area for opening scientific mysteries of this flora. The people of the Wazirabad have also been interviewed regarding effectiveness of remedious properties of these plants that have been using them from long time which revealed their prolonged dependence upon these local plants for their prime health problems. The confidence on medicine based over these plants is associated with their traditional beliefs.
