The effect of ion charge-mass ratio on adsorption of heavy metals on magnetotactic bacteria

The magnetotactic bacteria have the properties of both capturing heavy metal ions and being quickly separated out from the wastewater, which makes them high quality adsorbents. The adsorption of ions usually shows selectivity in the multi component aqueous solutions. This paper investigated the mechanism of adsorption selectivity using the molecular dynamics method on the basis of periodic law of elements. A universal equation with respect to the mass, volume and charge of ions was deduced. Based on the analysis of the surficial properties, a model was built to describe the structure of magnetotactic bacteria using the organic groups. Then, the interface system of bacterium surface, aqueous solutions and heavy metal ions was developed and dynamics simulation was performed. It was found that the ion having smaller charge-mass ratio according to the periodic system of elements might be easier to be adsorbed. The ionic thermal motion could depress the adsorption of ions and might be one of the reasons which cause adsorption selectivity. Furthermore, the larger charge-mass ions were more inclined to be drifting away from the bacteria in the simulation.
Transaction Logging Unleashed with NVRAM ∗

Most single node database systems such as PostgreSQL use centralized write-ahead logging [4]: log records are first buffered in DRAM and then flushed to stable storage upon commit to ensure durability and consistency. On today’s massively parallel hardware, however, this single log buffer design has become a bottleneck: as shown in Figure 1, on a 4-socket, 24-core server with hyperthreading (the OS sees 48 “CPUs”) logging gradually became the worst bottleneck with increasing parallelism: ∼45% of the CPU cycles are spent on contending for the log buffer (in green color). In this paper, we advocate using byte-addressable, non-volatile memory (NVRAM) as log buffers. The non-volatility and byteaddressability of NVRAM resurrect distributed logging—a once prohibitive technique for single node systems—to scale databases on modern hardware. We discuss the challenges and solutions brought by NVRAM and distributed logging. All of our techniques have been implemented based on the Shore-MT [1] storage manager. Since NVRAMs built with new materials (e.g., PCM) are not yet widely available, we consider flash-backed DRAM in our evaluation. We run a write-intensive telecommunications transaction (TATP Update Location) and the TPC-C benchmark. Evaluation results show that our approach can significantly ease the logging bottleneck and achieve ∼3x speedup over Aether [2], a state-ofthe-art centralized logging scheme.
Effects of spatially varying slip length on friction drag reduction in wall turbulence

A series of direct numerical simulation has been made of turbulent flow over hydrophobic surfaces, which are characterized by streamwise periodic micro-grooves. By assuming that the size of micro-grooves is much smaller than the typical length-scale of near-wall turbulent structures, the dynamical boundary condition is expressed by a mobility tensor, which relates the slip velocity and the surface shear stress. Based on the derived mathematical relationship between the friction drag and different dynamical contributions, it is shown how the turbulence contribution can be extracted and analyzed.
Hematoporphyrin derivatives: The ultrahigh performance liquid chromatography: Diode array: Electrospray ionization: Mass spectrometry analysis

Recent advances in the column technology have led to the development of small particles as stationary phase carriers in reversed-phase liquid chromatography for separation of large scale of molecules. This work represents an application of UHPLC (ultrahigh performance liquid chromatography with 1.9 μm C-18 particles) coupled with ESI-MS (electro spray ionization-mass spectrometry) and DAD (diode array) analysis for the identification of the mixture of porphyrins such as hematoporphyrin and protoporphyrin derivatives, widely known photosensitizers used in medicine. Five porphyrin derivatives were separated and identified in the hematoporphyrin mixture: hematoporphyrin IX, protoporphyrin IX, two hydroxyethyl-vinylderivatives and methyl-ester of protoporphyrin IX.
Simulation of the CERN GTS-LHC ECR ion source extraction system with lead and argon ion beams

A comprehensive study of beam formation and beam transport has been initiated in order to improve the performance of the CERN heavy ion injector, Linac3. As part of this study, the ion beam extraction system of the CERN GTS-LHC 14.5 GHz Electron Cyclotron Resonance Ion Source (ECRIS) has been modelled with the ion optical code IBSimu. The simulations predict self-consistently the triangular and hollow beam structures which are often observed experimentally with ECRIS ion beams. The model is used to investigate the performance of the current extraction system and provides a basis for possible future improvements. In addition, the extraction simulation provides a more realistic representation of the initial beam properties for the beam transport simulations, which aim to identify the performance bottle necks along the Linac3 low energy beam transport. The results of beam extraction simulations with Pb and Ar ion beams from the GTS-LHC will be presented and compared with experimental observations.
The Natural Resource Curse Revisited:Theory and Evidence from India

I construct a model of religion as an institution that provides community enforcement of contracts within families. Family altruism implies that family members cannot commit to reporting broken contracts to the community, so the community must monitor contract performance as well as in icting punishment. The community has less information than family members, and so community monitoring is ine cient. I provide evidence from a study of Amish institutions, including qualitative evidence from sociological accounts and quantitative evidence from a novel dataset covering nearly the entire Amish population of Holmes county, Ohio. I nd that 1) Amish households are not unitary, 2) the Amish community helps to support families by in icting punishments on wayward family members, 3) without the community Amish people have di culty committing to punishing family members, and 4) Amish community membership strengthens family ties, while otherwise similar religious communities in which there is less need for exchange between family members have rules that weaken family ties. My model has implications for understanding selection into religious practice and the persistence of culture.
Lessons and learnings from mid-term evaluation of watersheds: experiences in God's own country' of Kerala, India.

Management of rainfed agriculture in low or high rainfall regions necessitates equal attention. In both situations, farm households are beset with problems detrimental to agricultural productivity. In the high rainfall area of Kerala specifically in three watersheds supported by the National Watershed Development Project for Rainfed Areas (NWDPRA) launched in the early 1990s, its system of watershed management revealed insights relevant to generic sustainable management of resources. The project, which consists of improved biophysical interventions and enhanced social resources, has significantly abated the major problem of soil erosion and water run-off. In turn, these contributed to a better agricultural livelihood system to an extent. Ensuring community participation by putting into practice demand-driven activities, involving local institutions, developing their commitment and capacities, is the major insight towards the successful management of the watersheds and livelihoods of the NWDPRA project. Institutional reforms in the project like the creation of an autonomous body; the watershed committee (WC) that oversees the watershed activities with legitimate participation of the gram panchayat (system of self-governance at the village level); the panchayat president as a member of the WC provided the avenue for ensuring the cooperation of the village. The initial outcomes of the (participatory) monitoring and evaluation (PME) show need for strengthening capacity building in the areas of productivity enhancement initiatives, better water use strategies, maintenance of water harvesting structures and more importantly programs need to be more inclusive to benefit large number of community members. However, some areas still needing attention are inevitable due to the dynamism of the watershed system. There is the need to address issues of the social exclusion of some segments of the community and making markets work for broad based economic growth, which can then make the watershed project even more sustainable.
Autopoietic Features of the Urban Body's Elements - Similarity studies on network elements' attributes

The methodology presented in this paper is grounded on the analysis and relational relocation of attributes of the urban body, deriving from the reconstruction of the urban body as a network configuration. In contrast to the hierarchical constructions, network constructions allow for multiple connections between elements, therefore being closer to the complexity of the associative forces found in the structure of the urban body.Similarity function is applied in an attempt to restructure those attributes of the urban body which emerge from the position of each element (node) in relation to other elements of the network and not from the Cartesian topology. Being able to represent material elements as nodes, counter-bodies deriving from autopoietic -network functions emerge, allowing for an inquiry in what concerns the autopoietic features of the urban body in general, focusing on the application of autopoietic functions which generate the urban body parts and components and on the multiplicity of elements' structure, in terms of association of crowds of elements and sets of attributes' values, aiming at the redefinition of proximity as similarity and of remoteness as difference.

Pensamiento Reflexivo , Autoeficacia , Autoestima y Rendimiento Académico de Estudiantes Iranís con Inglés como Segunda Lengua en Educación Superior : ¿ Existe una Relación ?

The present study investigated the relationship between reflective thinking, general self-efficacy, self-esteem and academic achievement of Iranian EFL students. To this end, 132 Iranian EFL students from three state universities were recruited. To collect the data, the participants completed four questionnaires, namely background information questionnaire, the reflective thinking skills questionnaire, the general self-efficacy scale and Rosenberg self-esteem scale. The results of two correlation matrixes revealed that there were statistically significant positive relationships between general self-efficacy, self-esteem and academic achievement of Iranian EFL students, while reflective thinking had no significant relationship with selfesteem, self-efficacy and academic achievement of the participants; in addition, no significant relationship between the components of reflective thinking and academic achievement of Iranian EFL students was observed. Moreover, the results of multiple regression analysis showed that between self-esteem and self-efficacy, the former was a stronger predictor of academic achievement of the Iranian EFL students.
Multi-model mean nitrogen and sulfur deposition from the Atmospheric Chemistry and Climate Model Intercomparison Project (ACCMIP): evaluation of historical and projected future changes

Abstract. We present multi-model global datasets of nitrogen and sulfate deposition covering time periods from 1850 to 2100, calculated within the Atmospheric Chemistry and Climate Model Intercomparison Project (ACCMIP). The computed deposition fluxes are compared to surface wet deposition and ice core measurements. We use a new dataset of wet deposition for 2000–2002 based on critical assessment of the quality of existing regional network data. We show that for present day (year 2000 ACCMIP time slice), the ACCMIP results perform similarly to previously published multi-model assessments. For this time slice, we find a multi-model mean deposition of approximately 50 Tg(N) yr−1 from nitrogen oxide emissions, 60 Tg(N) yr−1 from ammonia emissions, and 83 Tg(S) yr−1 from sulfur emissions. The analysis of changes between 1980 and 2000 indicates significant differences between model and measurements over the United States but less so over Europe. This difference points towards a potential misrepresentation of 1980 NH3 emissions over North America. Based on ice core records, the 1850 deposition fluxes agree well with Greenland ice cores, but the change between 1850 and 2000 seems to be overestimated in the Northern Hemisphere for both nitrogen and sulfur species. Using the Representative Concentration Pathways (RCPs) to define the projected climate and atmospheric chemistry related emissions and concentrations, we find large regional nitrogen deposition increases in 2100 in Latin America, Africa and parts of Asia under some of the scenarios considered. Increases in South Asia are especially large, and are seen in all scenarios, with 2100 values more than double their 2000 counterpart in some scenarios and reaching > 1300 mg(N) m−2 yr−1 averaged over regional to continental-scale regions in RCP 2.6 and 8.5, ~ 30–50% larger than the values in any region currently (circa 2000). However, sulfur deposition rates in 2100 are in all regions lower than in 2000 in all the RCPs. The new ACCMIP multi-model deposition dataset provides state-of-the-science, consistent and evaluated time slice (spanning 1850–2100) global gridded deposition fields for use in a wide range of climate and ecological studies.

Spread of odontogenic infections in the elderly: Prevalence and characteristic multidetector CT findings

Purpose: To analyze spread of odontogenic infections in the elderly, especially the prevalence and characteristic multidetector computed tomography (MDCT) findings. Materials and methods: Ninety-seven patients with odontogenic infection who underwent 64-row MDCT were evaluated in this study. The study patients comprised 31 elderly patients (60 years) and 66 adults (< 60 years). Age, gender, location of causal tooth, and spread of odontogenic infections with MDCT were analyzed. Results: The elderly patients (74.2%) had higher ratio with female compared to the adults (57.6%). The buccal space (93.5%) was the most common spread of odontogenic infections for the elderly patients, followed by the masticator space (54.8%) and submandibular space (45.2%), whereas the buccal space (97.0%) was the most common spread of odontogenic infections for the adults, followed by submandibular space (65.2%) and masticator space (51.5%). Logistic multivariate regression analysis for odontogenic infections in the elderly demonstrated that the gender (odds ratio = 3.462, P = .024) and submandibular space (odds ratio = 0.168, P = .013) were significant variable. Conclusions: The study showed the prevalence and characteristic MDCT findings of spread of odontogenic infections in the elderly.
Virtual structural health monitoring and remaining life prediction of steel bridges

In this study a structural health monitoring (SHM) system is combined with bridge weigh-in-motion (B-WIM) measurements of the actual traffic loading on a bridge to carry out a fatigue damage calculation. The SHM system uses the ‘virtual monitoring’ concept, where all parts of the bridge that are not monitored directly using sensors, are ‘virtually’ monitored using the load information and a calibrated finite element (FE) model of the bridge. Besides providing the actual traffic loading on the bridge, the measurements are used to calibrate the SHM system and to update the FE model of the bridge. The newly developed virtual monitoring concept then uses the calibrated FE model of the bridge to calculate stress ranges and hence to monitor fatigue at locations on the bridge not directly monitored. The combination of a validated numerical model of the bridge with the actual site-specific traffic loading allows a more accurate prediction of the cumulative fatigue damage at the time of measurement and facilitates.
Utilizing Complex-valued Network for Learning to Compare Image Patches

At present, the great achievements of convolutional neural network(CNN) in feature and metric learning have attracted many researchers. However, the vast majority of deep network architectures have been used to represent based on real values. The research of complex-valued networks is seldom concerned due to the absence of effective models and suitable distance of complex-valued vector. Motived by recent works, complex vectors have been shown to have a richer representational capacity and efficient complex blocks have been reported, we propose a new approach for learning image descriptors with complex numbers to compare image patches. We also propose a new architecture to learn image similarity function directly based on complex-valued network. We show that our models can perform competitive results on benchmark datasets. We make the source code of our models publicly available.
The influence of seasonal processes on geochemical profiles and foraminiferal assemblages on the outer shelf of the Bay of Biscay

Benthic foraminifera are widely used tools to reconstruct paleoenvironments. They reflect bottom water oxygen concentrations and organic carbon flux. To increase their accuracy as proxies, seasonal variability of foraminiferal populations from the outer shelf of the Bay of Biscay (150m water depth) was followed over a 3-year period. The selected area is characterized by seasonal variation in organic matter deposition. A strong interaction between organic detritus input, macrofaunal bioturbational activity, the degree of separation of redox zones and the reproduction, growth and migrational response of benthic foraminifera was found. During periods of high labile organic matter input, as occurs during spring bloom conditions, the redox zonation was not well established. Different organic degradation pathways occurred at the same depth intervals in the sediment. Shallow infaunal species reacted in response to the high nutrient content with rapid growth (Bolivina subaenariensis) or reproduction (Epistominella vitrea, Bolivina seminuda, Bolivina dilatata/spathulata). Infaunally living foraminifera, Chilostomella oolina and to lesser extent Nonion scaphum, migrated to the sediment surface in reaction the increase organic matter input to the seafloor. This migration could have been induced by the more intensive overlapping of redox zones that were perhaps better separated vertically in winter. However, this migration could also have been triggered by the occurrence of fresh phytodetritus in the sediment, becoming even available in slightly deeper sediment level due to the increased bioturbation activity. r 2006 Elsevier Ltd.

On 0-Complete Partial Metric Spaces and Quantitative Fixed Point Techniques in Denotational Semantics

In 1994, Matthews introduced the notion of partial metric space with the aim of providing a quantitative mathematical model suitable for program verification. Concretely, Matthews proved a partial metric version of the celebrated Banach fixed point theorem which has become an appropriate quantitative fixed point technique to capture the meaning of recursive denotational specifications in programming languages. In this paper we show that a few assumptions in statement of Matthews fixed point theorem can be relaxed in order to provide a quantitative fixed point technique useful to analyze the meaning of the aforementioned recursive denotational specifications in programming languages. In particular, we prove a new fixed point theorem for self-mappings between partial metric spaces in which the completeness has been replaced by 0-completeness and the contractive condition has been weakened in such a way that the new one best fits the requirements of practical problems in denotational semantics. Moreover, we provide examples that show that the hypothesis in the statement of our new result cannot be weakened. Finally, we show the potential applicability of the developed theory by means of analyzing a few concrete recursive denotational specifications, some of them admitting a unique meaning and others supporting multiple ones.
NuSTAR observations of Mrk 766: distinguishing reflection from absorption

We present two new NuSTAR observations of the narrow-line Seyfert 1 (NLS1) galaxy Mrk 766 and give constraints on the two scenarios previously proposed to explain its spectrum and that of other NLS1s: relativistic reflection and partial covering. The NuSTAR spectra show a strong hard (>15 keV) X-ray excess, while simultaneous soft X-ray coverage of one of the observations provided by XMM–Newton constrains the ionized absorption in the source. The pure reflection model requires a black hole of high spin (a > 0.92) viewed at a moderate inclination (⁠i=46^(+1)_(−4)∘⁠). The pure partial covering model requires extreme parameters: the cut-off of the primary continuum is very low (⁠22^(+7)_(−5) keV) in one observation and the intrinsic X-ray emission must provide a large fraction (75 per cent) of the bolometric luminosity. Allowing a hybrid model with both partial covering and reflection provides more reasonable absorption parameters and relaxes the constraints on reflection parameters. The fractional variability reduces around the iron K band and at high energies including the Compton hump, suggesting that the reflected emission is less variable than the continuum.
