Chemical kinetic modeling of low pressure methylcyclohexane flames.

Alkyl cyclohexanes are important components in gasoline, diesel, and jet fuels. With the recent introduction of oil-sand derived petroleum feedstocks, the levels of alkyl cyclohexanes in fuels are likely to increase. Elevated levels of alkyl cyclohexanes in fuels are expected to increase soot emissions when utilized in combustion devices. With expected increases in alkyl cyclohexanes in fuels, more accurate chemical kinetic pathways and rate constants are needed to understand the chemical pathways responsible for increased soot production. To improve the accuracy of chemical kinetic models, low pressure premixed flames with tunable UV molecular beam sampling provides a wealth of speciation data for model validation. This data will help to understand the flame chemistry of alkyl cyclohexanes and their production of soot precursors like benzene, acetylene, fulvene and others. In this study, we have focused on methyl cyclohexane (MCH) which is the simplest alkyl cyclohexane. In a recently published study of methyl cyclohexane flames by the present authors, the LLNL MCH model and other available literature models were found to be inaccurate in predicting many intermediate species in low pressure MCH flames. This finding has led to improvements of the MCH chemical kinetic model. The following submodels have been replaced in the previous 2007 LLNL model: The C1-C4 base chemistry using the Saudi Aramco version 1, the aromatics base chemistry using the latest LLNLNUIG base model, and the cyclohexane submodel with the more recent LLNL 2007 version. Also, there are additional updates of the MCH mechanism. The abstraction reactions from MCH were replaced using recent experimentally measured values and standardized using the latest LLNL reaction rate rules. The previous 2007 MCH model lumped many of unsaturated ring products of MCH that lead to soot precursors. These species have now been expanded to include all the relevant isomers with their associated chemical kinetic reaction paths and rate constants. The model now tracks the intermediate unsaturated methylcyclohexane species with much more fidelity and predicts their experimentally measured concentrations with much more accuracy. The improved MCH chemical kinetic model was employed using Chemkin Pro® and the experimentally measured temperature profile to model the low pressure flames of equivalence ratios of 1 and 1.9. A more accurate experimental temperature profile than previously available was obtained using the FKT transfer function. In the paper, the experimentally measured and predicted cyclic species, aromatics, and soot precursors are compared and discussed. Additionally, the production and consumption of key aromatic species is tracked to identify the important chemical pathways leading to aromatics, and soot precursors in these MCH

Genetic marking with the D LNGFR-gene for tracing goat cells in bone tissue engineering q

The use of bone marrow derived stromal cells (BMSC’s) for bone tissue engineering has gained much attention as an alternative for autologous bone grafting. Little is known however, about the survival and differentiation of the cells, especially in the clinical application. The aim of this study was to develop a method to trace goat BMSC’s in vivo. We investigated retroviral genetic marking, which allows stable expression of the label with cell division. Goat BMSC’s were subjected to an amphotropic envelope containing a MoMuLV-based vector expressing the human low affinity nerve growth factor receptor (DLNGFR). Labeling efficiency and effect on the cells were analyzed. Furthermore, transduced cells were seeded onto porous ceramic scaffolds, implanted subcutaneously in nude mice and examined after successive implantation periods. Flow cytometry indicated a transduction efficiency of 40–60%. Immunohistochemistry showed survival and subsequent bone formation of the gene-marked cells in vivo. Besides, marked cells were also found in cartilage and fibrous tissue. These findings indicate the maintenance of the precursor phenotype following gene transfer as well as the ability of the gene to be expressed following differentiation. We conclude that retroviral gene marking with DLNGFR is applicable to trace goat BMSC’s in bone tissue engineering research. 2003 Orthopaedic Research Society. Published by Elsevier Ltd.

The architecture of the PLATO instrument control unit

The "PLAnetary Transits and Oscillations of stars" (PLATO) is one of the three selected candidates for the next M-class mission in the framework of the European Space Agency Cosmic Vision 2015-2025, currently expected for launching by the end of 2018. PLATO aims to find and characterize exoplanetary systems by detecting planetary transits and carrying out asteroseismology of their parent stars. The Instrument Control Unit (ICU) is part of the on-board Data Processing System and it is devoted to process and compress digital data inputs from 18 processing units, collecting analog data from 34 FPAs hosting 4 CCDs each. ICU will be also in charge of managing telemetry and telecommands to and from the Service Module (SVM) and to collect the payload's housekeeping and science data. This paper will describe the ICU architecture and functionalities addressing the mission scientific requirements.
Vision-based UAV pose estimation

The popularity of Unmanned Aerial Vehicles(UAVs) has increased dramatically in the past few decades. The main challenging task for UAVs operation is to find their position and orientation accurately and continuously during the flight, using the onboard sensors (camera in our case). There are lots of different approaches for UAV pose estimation in literature now. Several different approach and their problems in real-life application were studied in this research. We chose the real time single camera SLAM method [12], because our robot was equipped with an onboard camera, and MonoSLAM had proved its reliability in previous localization experiments[12],[10],[6],[11]. In our work, we obtained the ground truth by the Vicon cameras. The experimental results suggest that this method can be reliably used in the control of indoor UAV navigation.
Aalborg Universitet Peatland Acidobacteria with a dissimilatory sulfur metabolism

Sulfur-cycling microorganisms impact organic matter decomposition in wetlands and consequently greenhouse gas emissions from these globally relevant environments. However, their identities and physiological properties are largely unknown. By applying a functional metagenomics approach to an acidic peatland, we recovered draft genomes of seven novel Acidobacteria species with the potential for dissimilatory sulfite (dsrAB, dsrC, dsrD, dsrN, dsrT, dsrMKJOP) or sulfate respiration (sat, aprBA, qmoABC plus dsr genes). Surprisingly, the genomes also encoded DsrL, which so far was only found in sulfur-oxidizing microorganisms. Metatranscriptome analysis demonstrated expression of acidobacterial sulfur-metabolism genes in native peat soil and their upregulation in diverse anoxic microcosms. This indicated an active sulfate respiration pathway, which, however, might also operate in reverse for dissimilatory sulfur oxidation or disproportionation as proposed for the sulfur-oxidizing Desulfurivibrio alkaliphilus. Acidobacteria that only harbored genes for sulfite reduction additionally encoded enzymes that liberate sulfite from organosulfonates, which suggested organic sulfur compounds as complementary energy sources. Further metabolic potentials included polysaccharide hydrolysis and sugar utilization, aerobic respiration, several fermentative capabilities, and hydrogen oxidation. Our findings extend both, the known physiological and genetic properties of Acidobacteria and the known taxonomic diversity of microorganisms with a DsrAB-based sulfur metabolism, and highlight new fundamental niches for facultative anaerobic Acidobacteria in wetlands based on exploitation of inorganic and organic sulfur molecules for energy conservation.
Metabolism and carbon exchange in microplankton of the Grand Banks (Newfoundland)

We measured simultaneously the size-distribution of oxygen consumption, inorganic and orgamc dissolved carbon assimilation, and the standing stocks of phytoplankton and bacteria, to develop simple carbon budgets and "C exchange models for the microplankton communities of a large conhnental shelf system. In spring samples (dominated by large-celled dlatoms) community respiration consumed 33 to 100 % or more of the gross primary production (GPP) measured by the 0,-light-anddark-bottle technique and was apparently due entirely to microheterotrophs. In fall samples (dominated by flagellates) community respiration consumed 100 % or more of the measured GPP, and appeared on average to be due equally to autotrophs and heterotrophs. Pnmary production, estimated by 14C-CO2 assimilation into particulate matter, often greatly underestimated GPP and community metabolism measured by the 0, technique, with apparent photosynthetic quotients (PQ) of about 5.0 in the spring samples. Modelling of the tracer dynamics suggested large rates of DOC release (> particulate production) from a small and rapidly cycling pool w i t h the autotrophs as the cause of the large apparent PQ's. The large share of primary production consumed by small microheterotrophs ( c 5 or l p) and frequent lack of positive net community production suggested a low efficiency for the transfer of microheterotrophic production to larger or. ;a~isn? s.
Possibilistic Missing Data Estimation ANAS

An approach that deals with the heterogeneity and the imperfection of information elements which constitute the objects in large databases has been proposed in this paper. Unlike the prior works that separately tackle these aspects using complex and conditional techniques, our method is general and takes account of them within a simple, flexible, and robust unified framework. It is fundamentally based on two fuzzy monotone measures: the possibility and the necessity degrees introduced in the theory of possibilities. A simple concrete example will also be given to clarify and to simply illustrate the main steps of computation, pointing out the outperformance and the robustness of the proposed strategy.

Distribution patterns and genetic variability of three stream-dwelling fish species

Present study established correlations between the spatial distribution of three stream-dwelling fish species (chub, stone loach and gudgeon), the environmental variables which affect their distribution, and the genetic structure of their assemblages, in a North Hungarian drainage system. The spatial distribution of gudgeon and stone loach (which have more specific habitat needs) was affected by elevation, slope and distance from the mouth. Chub occurred frequently in the wider and deeper streams of the hills with higher velocity, but was repeatedly caught in lowland situated sections close to the mouth as well. Genetic data obtained with AFLP were correlated with distribution and as a result higher genetic distances were revealed among gudgeon and stone loach than among chub assemblages. The assemblages of the former two species show a clear pattern of isolation by distance. Results suggest that lowland sections of the studied streams might act as ecological barriers for stone loach and gudgeon assemblages, but not for the chub. Hence, in this drainage system the stone loach and gudgeon appear with separated populations while the chub is characterized by a metapopulation structure.
Nutraceutical Properties of Meat from Grazing Podolian Young Bulls

The effect of rearing system (pasture with supplementation 15% crude protein OUT15 vs indoorIND) on meat nutritional and nutraceutical properties was evaluated in twenty Podolian young bulls. Meat quality characteristics were measured on three different muscles (Longissimus dorsi, LD, Semimembranosus, SM, Semitendinosus, ST), vacuum-packaged and chilled stored at 2℃ - 4℃ for 15 days. No differences were found on chemical composition in meat from animals reared with different rearing system. Pasture with supplementation produced an improvement in fatty acid composition with a higher polyunsaturated fatty acid percentage, particularly, conjugated linoleic acids (CLA) and very long chain ω3 PUFA, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Meat from young bulls reared at pasture with supplementation showed in all examined muscles the highest α-tocopherol content compared with meat from IND group. On the other hand, malondialdehyde content was not affected by the feeding treatment.
Making customer relationship management systems entrepreneurial

Customer relationship management systems (CRMS) are designed to facilitate and pre-empt customer-centric needs and wishes. CRMS designers suggest that CRMS can provide solutions to hotel customer problems and provide for customer needs by recording guest history. Databases such as CRMS are a “systems school” (Earl, 2001), and are considered a form of knowledge management. As a result, the knowledge creation process is initially set in motion by a data, which is entered into the CRMS and retrieved requires a solution that will be to a customer need of some description. Whilst CRMS are data storage for guest history, they also have the potential to support new ideas, innovation it is suggested that can be sources of new knowledge leading to innovation that can potentially enhance the business. Alternatively, research evidenced in this paper argues that CRMS are used as expensive glorified filing systems and the potential for entrepreneurial innovation remains largely untapped. Conversely, what can be seen is that the system, which is supposed to enable and support innovation, can, in fact, reduce the ability of the organisations to develop new ideas. The system becomes distracting and prescriptive. In addition the CRMS can create in the minds of the users an illusion of busyness, of apparent knowledge creation when, in fact, the opposite is true. A change in the way CRMS are viewed and supported is required for organisations to manage the potential learning and knowledge creation processes from CRMS that can result in development of an innovative culture.

Application of the Normalized Surface Magnetic Source Model to a Blind Unexploded Ordnance Discrimination Test

The Normalized Surface Magnetic Source (NSMS) model is applied to unexploded ordnance (UXO) discrimination data collected at Camp Sibert, AL, with the EM63 electromagnetic induction sensor. The NSMS is a fast and accurate numerical forward model that represents an object's response using a set of equivalent magnetic dipoles distributed on a surrounding closed surface. As part of the discrimination process one must also determine the location and orientation of each buried target. This is achieved using a physics-based technique that assumes a target to be a dipole and extracts the location from the measured magnetic field vector and the scalar magnetic potential; the latter is reconstructed from field measurements by means of an auxiliary layer of magnetic charges. Once the object's location is estimated, the measured magnetic field is matched to NSMS predictions to determine the time- dependent amplitudes of the surface magnetic sources, which in turn can be used to generate classifying features. This paper shows the superior discrimination performance of the NSMS model.
Evaluation of cytotoxicity and oxidative stress induced by alcoholic extract and oil of Lepidium Sativum seeds in human liver cell line HepG 2

Since, the primary site of drug metabolism is the liver, that plays a major role in metabolism, digestion, detoxification, and elimination of substances from the body, the present studies were designed to investigate the possible adverse effect of alcoholic extract of seeds of Lepidium sativum (LSA) and Lepidium sativum seed oil (LSO) on HepG2 cells, a human liver cell line. LSA and LSO induced cell viability by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) and neutral red uptake (NRU) assays. Morphological changes, lipid peroxidation, glutathione, catalase, and superoxide dismutase activities in HepG2 cells were studied. Cells were exposed to 25 to 1000 μg/ml of LSA and LSO for 24 h. The results show that LSA and LSO reduced cell viability, and altered the cellular morphology in dose dependent manner. Concentrations (100 to 1000 μg/ml) of LSA and LSO were found to be cytotoxic, whereas 50 μg/ml and lower concentrations did not cause any significant adverse effect in cell viability of HepG2 cells. LSA and LSO were also found to induce oxidative stress in dosedependent manner indicated by decrease in glutathione level, catalase activity, and SOD activity and an increase in lipid peroxidation. The results indicate that LSA and LSO induced oxidative stress mediated cytotoxicity in HepG2 cells.
Instability of the Atlantic overturning circulation during Marine Isotope Stage 3

Variations in the strength of the Atlantic meridional overturning circulation (AMOC) were involved in the occurrences of Dansgaard‐Oeschger (D‐O) events during Marine Isotope Stage 3 (MIS3). The stability of the AMOC to North Atlantic freshwater perturbations is studied using a comprehensive climate model under MIS3 boundary conditions. An AMOC stability diagram constructed from a series of equilibrium freshwater perturbation experiments reveals a highly nonlinear dependence of AMOC strength on freshwater forcing. The MIS3 baseline state is remarkably unstable with respect to minor perturbations. The global climate signal associated with a change in AMOC strength is consistent with a transition from an interstadial to a stadial state including an annual mean surface air temperature drop of ~8 K in central Greenland. We suggest that minor freshwater perturbations in the hydrologic cycle, e.g., related to ice sheet processes, had the potential to trigger D‐O‐type climate shifts associated with a threshold in the atmosphere‐ocean system.

The simultaneous occurrence of surge and discharge extremes for the Rhine delta

Abstract. The low-lying Netherlands is at risk from multiple threats of sea level rise, storm surges and extreme river discharges. Should these occur simultaneously, a catastrophe will be at hand. Knowledge about the likelihood of simultaneous occurrence or the so-called "compound effect" of such threats is essential to provide guidance on legislation for dike heights, flood barrier design and water management in general. In this study, we explore the simultaneous threats of North Sea storm surges and extreme Rhine river discharge for the current and future climate in a large 17-member global climate model ensemble. We use a simple approach, taking proxies of north-northwesterly winds over the North Sea and multiple~day precipitation averaged over the Rhine basin for storm surge and discharge respectively, so that a sensitivity analysis is straightforward to apply. By investigating soft extremes, we circumvent the need to extrapolate the data and thereby permit the model's synoptic development of the extreme events to be inspected. Our principle finding based on the climate model data is that, for the current climate, the probability of extreme surge conditions following extreme 20-day precipitation sums is around 3 times higher than that estimated from treating extreme surge and discharge probabilities as independent, as previously assumed. For the future climate (2070–2100), the assumption of independence cannot be rejected, at least not for precipitation sums exceeding 7 days.
A GGRESSIVE DISPLACEMENT OF CARPENTER BEES X YLOCOPA NIGRITA FROM FLOWERS OF L AGENARIA SPHAERICA ( C UCURBITACEAE ) BY TERRITORIAL MALE E ASTERN O LIVE S UNBIRDS ( C YANOMITRA OLIVACEA ) IN T ANZANIA

Male Eastern Olive Sunbirds (Cyanomitra olivacea) and Xylocopa nigrita carpenter bees in Tanzania both utilise the flowers of male plants of Lagenaria sphaerica (Cucurbitaceae) as a source of nectar. The sunbirds set up territories defending this nectar resource. Observations of interactions between the sunbirds and the carpenter bees show that the bees are aggressively displaced from flowers when spotted by the birds. Only the bees can be considered as legitimate pollinators as the birds do not contact the anthers of the male flowers and were never seen visiting nectarless female flowers of Lagenaria sphaerica. Such territory defence may have implications for the frequency of movement and composition of pollen being transferred from male to female flowers which warrants further research.
Taking the Plunge: An Introduction to Undertaking Seascape Genetic Studies and Using Biophysical Models

The field of seascape genetics aims to evaluate the effects of environmental features on spatial genetic patterns of marine organisms. Although many methods of genetic analysis and inference appropriate to ‘‘marine landscapes’’ derive from terrestrial landscape genetics, aspects of marine living introduce special challenges for assessing spatial genetic variation. For instance, marine organisms are often highly dispersive, so that genetic patterns can be subtle, and the temporal variability of the marine environment makes these patterns difficult to characterise. Tools and techniques from oceanography can help describe the highly connected and dynamic nature of the marine environment. In particular, models incorporating physical oceanography and species attributes in realistic simulations (e.g. biophysical models) can help us understand this complex process and formulate spatially explicit biologically-informed predictions of gene flow. Thus, researchers embarking on a seascape genetic study need a solid understanding of marine organisms and spatial genetics perhaps combined with knowledge of physical oceanography and ecological modeling. Although some researchers may acquire proficiency in all of these areas, seascape genetic studies incorporating biophysical modeling are likely to bring together groups of investigators with complementary expertise. This preliminary guide is intended to be a starting point for a reader new to either seascape genetics or biophysical models.
