Carbon Capture and Storage

1 What is it? Carbon dioxide Capture and Storage (CCS) refers to a set of technologies which can be installed for the reduction of carbon dioxide (CO 2) emissions in power generation and industrial processes. The process consists of the separation of CO 2 from large industrial and energy-related point sources, subsequent compression, transportation to a storage location and long-term isolation (i.e. storage) from the atmosphere. The large point sources of CO 2 include large fossil fuel or biomass power plants, major CO 2-emitting industries (steel and cement production), natural gas production, synthetic fuel plants and fossil fuel-based hydrogen production plants. CO 2 can be stored in geological formations (e.g. oil and gas fields, unminable coal beds and deep saline aquifers), in the ocean (direct release into the ocean water column or close to the deep seafloor) and via industrial fixation in inorganic carbonates (Figure 1). Alternatively, CO 2 can also be used as an input to other industrial processes. • Capture: There are three different types of CO 2 capture technologies: post-combustion, pre-combustion and oxy-fuel combustion. The selection of the capture system mainly depends on the plant design (e.g. concentration of CO 2 in the flue gas stream, pressure and temperature of the gas stream, retrofitted or newly built plant). • Transportation: Pipelines are preferred for transporting large amounts of CO 2 onshore. For larger distances oversea, the use of ships could be economically more attractive.
A pr 2 01 9 Interface effects of strange quark matter

The interface effects play important roles for the properties of strange quark matter (SQM) and the related physical processes. We show several examples on the implications of interface effects for both stable and unstable SQM. Based on an equivparticle model and adopting mean-field approximation (MFA), the surface tension and curvature term of SQM can be obtained, which are increasing monotonically with the density of SQM at zero external pressure. For a parameter set constrained according to the 2M⊙ strange star, we find the surface tension is ∼2.4 MeV/fm, while it is larger for other cases.

Technology has elevated to grab an important position in humans life, the best example is smartphones. They offer access to network as well as online banking transactions, where simplification of human labour affects security and user authentication, and passwords are first line of defense, it’s crucial to pick a strong password. Online banking applications currently use alphanumerical usernames and passwords for authentication, which are exposed to eves dropping, attacks, and shoulder surfing. Users often choose either easy to remember passwords, which can be easily guessed or difficult ones, which tend to be forgotten. The paper revolves around the views, limitation of current system and offers a dynamic biometrics, as it can be easily integrated into the existing computer security systems with minimal alteration and user intervention. The main objective is to secure using cued click point (CCP), which is one click based graphical password scheme for sequence of images and measuring, assessing humans typing rhythm, it’s based upon the human tendency to memorize graphical passwords more comfortably.
A Comparative Study of Insulators on Magnetic Properties of Sendust Based Nanocomposite Powder Cores

Abstract: In this study, Sendust (Fe85Si9.6Al5.4) nanostructure alloy was prepared by mechanical alloying and was characterized by X-ray diffraction. In addition, the alloy’s morphology and its distribution particle size were investigated by scanning electron microscopy method. The alloyed powders were insulated with 4wt% of three different insulating materials including polyvinyl alcohol, epoxy resin, and sodium silicate. Then, 0.5 wt% zinc stearate was added as a lubricant and the composites were formed at a pressure of 1600 MPa in a torodial die. These cores were annealed in Ar atmosphere at 350 to 450 oC for 1 h. Some of the magnetic parameters of the as-milled and annealed samples were measured and compared with each other in the frequency range of 4 to 1000 kHz. The results showed that polyvinyl alcohol is not a suitable insulating agent for insulating this alloy. In addition, the real part of the initial magnetic permeability of the magnetic powder core insulated by sodium silicate in comparison with that insulated by epoxy resin is a bit smaller, but more reduction of the imaginary part of former results in an increase the Q-factor throughout measuring frequency range. The results show that annealing is more effective on improvement of the measured magnetic properties of the samples insulated with sodium silicate than that insulated with epoxy resin.
2 0 1 4 ) 0 1 9 3 D simulations of the multi-wavelength emission from young supernova remnants including efficient particle acceleration

Within our Galaxy, supernova remnants (SNRs) are believed to be the major sources of cosmic rays, up to the knee of the cosmic ray spectrum. The detection of non-thermal radiation from SNRs, in X-rays over the past two decades, and finally in γ-rays over the past decade, has proved the presence of energetic particles in these objects. However important questions remain regarding the share of the hadronic and leptonic components, and the fraction of the supernova energy channelled into these. If protons are efficiently accelerated at the blast wave, this should impact the dynamics of the SNR itself, and therefore its morphology and spectral properties. In this paper we show how these effects can be investigated by the means of 3D numerical simulations. Our code couples the hydrodynamic evolution of the SNR with a non-linear kinetic model of diffusive shock acceleration, which allows us to produce synthetic projected maps to be compared with observations. We show how the presence of energetic protons can be inferred from the broadband emission of SNRs: 1) relativistic particles modify the properties of the shocked plasma, which affects the thermal X-ray emission, and 2) streaming particles can amplify the ambient magnetic field, which affects the non-thermal radio to γ-ray emission.
C provenance semantics: examples

This note discusses the design of provenance semantics for C, looking at a series of examples. We consider three variants of the provenance-not-via-integer (PNVI) model: PNVI plain, PNVI address-exposed (PNVI-ae) and PNVI address-exposed user-disambiguation (PNVI-ae-udi), and also the provenance-via-integers (PVI) model. The examples include those of Exploring C Semantics and Pointer Provenance [POPL 2019] (also available as ISO WG14 N2311 http://www.open-std.org/jtc1/sc22/wg14/ www/docs/n2311.pdf), with several additions. This is based on recent discussion in the C memory object model study group. It should be read together with the two companion notes, one giving detailed diffs to the C standard text (N2362), and another giving detailed semantics for these variants (N2364).
Interval of time uncertainty in visual detection

The effects of increasing the length of an interval of continuous temporal uncertainty (ITU) on the detectability of visual signals were investigated in a 'Yes/No' detection situation. Ss were uncertain about when a signal might occur within a given observation interval, the duration of which was varied. Longer intervals of uncertainty resulted in a decrement in detectability, which was shown to be directly attributable to increased false alarm rates. It was suggested that observers have more opportunities for confusing signals with noise. The time course of detectabil.ity within a given ITU was also investigated, but there were no significant variations.
Supporting engagement in research through a game design competition

Digital games are an engaging medium that have previously been used for communicating research to a variety of audiences. However, there is an opportunity for engaging people more deeply by involving them in creating games. This article reports on a game design competition, based on participatory design principles and game jam practices, which challenged university students to design games within the context of a research project. Based on their interpretations of research on human error in health care, teams created four games to be disseminated online to a wider public audience. We outline the competition format and reflect on the extent to which it was successful.
Parton Distributions and Neutrino Scattering : Uncertainties of Global QCD Analysis

This paper presents comparisons between recent models of parton distribution functions (viz. CTEQ6) and experimental data from NuTeV deep inelastic neutrino scattering experiments. First, the basics of parton distribution functions will be described. These may be calculated using the Durham University program LHAPDF. Next we move on to an explication of the NuTeV neutrino deep inelastic scattering (DIS) experiment at Fermilab. We then present some of the leading-order (LO) cross-section calculations from QCD and their associated corrections. Finally, we compare error analysis for the previous CTEQ6 parton standard with the new ‘FIT4’ curves, and draw our conclusions. Our goal is to conduct both a graphical and a statistical analysis of the effect of these new PDFs in regards to the experimental data [1].
G A ] 4 F eb 2 01 1 Studies of methanol maser rings

We present the results of studies of a new class of 6.7 GHz meth anol maser sources with a ringlike emission structure discovered recently with the EVN. W e have used the VLA to search for water masers at 22 GHz and radio continuum at 8.4 GHz towards a sample of high-mass star forming regions showing a ring-like distribution of methan ol maser spots. Using the Gemini telescopes we found mid-infrared (MIR) counterparts of five methanol rings with a resolution of 0. "15. The centres of methanol maser rings are located withi n, ypically, only 0. "2 of the MIR emission peak, implying their physical relation with a cent ral star. These results strongly support a scenario wherein the ring-like structures appear at the ve ry early stage of massive star formation before either water-maser outflows or H II regions are seen.
Order Aggressiveness of Different Broker-Types in Response to Monetary Policy News

This paper examines the pattern of order aggressiveness, and the determinants of this pattern for institutional and retail brokers in the interval around monetary policy announcements. Utilizing a high-frequency dataset, with broker identifiers for each order submitted on the ASX over the period Dec 2007–Dec 2014, I identify a sharp increase in the number of orders submissions in the period following RBA announcements. Orders are more aggressive, and more abundant, when there is less information for investors to digest. On average, retail orders are more aggressive and are exclusively concerned with the likelihood of order execution. The submission decision of institutional brokers is more nuanced and evolves over time as market conditions change and information arrives. I also recognize differences in order aggressiveness attributable to firm-size and industry.
What explains the varying degree of export? Internal or external factors

Objective: The objective of this article is to determine and analyse export conditions by combining the entrepreneurial resource perspective and formal institutional approach. Research Design & Methods: Drawing on a representative sample of global nascent entrepreneurs, cross-level (random-effects) moderation analysis is applied to explicate the influence of a country’s formal institution on the relationship between entrepreneurial resource-based determinants and the degree of export, and this method enables the study of country-level slopes. Findings: The results suggest that there is a positive relation between self-efficacy and export and that people who have the willingness to pursue decisions or courses of action associated with uncertainty are more likely to export. In addition, the research findings also confirm the positive moderating effect of formal institutions on entrepreneurial resource aspects and the degree of export. Implications & Recommendations: The findings of the study have implications in particular for policy-makers who are interested in encouraging early export by influencing institutional dimensions. Policymakers have largely concentrated on institutions to increase entrepreneurial opportunities, but institutions may not be sufficient to stimulate international entrepreneurship. Contribution & Value Added: The originality of this work lies in adopting a more comprehensive approach in studying export by integrating entrepreneurial resource perspective with the institutional dimensions.
Isolation of a Singh ' s Aedes albopictus Cell Clone Sensitive to Dengue and Chikungunya Viruses

Twenty clones were isolated from cultured Aedes albopictus (Singh) cells in the presence of anti-Chikungunya (CHIK) virus serum. Each clone was tested for its yields of Dengue (DEN) viruses, types I, 2, 3 and 4, and also CHIK virus. Clone C6 showed the highest yield of each virus tested. Forty-three clones obtained by recloning C6 in the presence of anti-DEN sera showed almost the same virus yields as C6. One of the clones, C6/36, showed mild to extensive cytopathic effects several days after virus infection, in contrast to the original uncloned (SAAR) cells. Fluorescent antibody staining revealed that the amount of virus antigen accumulated in the cytoplasm was almost the same in every cell in the case of clone C6/36, while it was highly heterogeneous for uncloned SAAR cells. Growth curves of the viruses indicated that clone C6/36 gave a significantly higher yield for each virus than uncloned SAAR cells up to 7 days after infection. Virus sensitivity of the C6/36 clone did not change by growing the cells with the medium used for uncloned SAAR cells, nor did the virus sensitivity of uncloned cells increase in medium used for clone C6/36. However, the C6/36 clone became resistant to CHIK virus, but not to DEN or Sindbis viruses, after incubation with the medium used for another A. albopictus cell line (SAAK). The transfer of the specific resistance to CHIK may be mediated by some latent virus related to CHIK.
Accident detection system based on Internet of Things (IoT)- Smart helmet

The objective of our smart helmet is to provide the means for detecting and reporting accidents. The working of this smart helmet is very simple; vibration sensors are placed in different places of the helmet where the probability of hitting is more, which are connected to the microcontroller board. When the rider met with an accident and the helmet hits the ground, these sensors sense and gives to the microcontroller board, then controller extracts GPS location using the GPS module that is interfaced to it. When the data exceeds the minimum stress limit then the GSM module automatically sends a message to the registered emergency contacts and the link through which the location and the speed of the victim will be displayed in the mobile application and in the web application.
Utilization for by products of banana-A Review

Today bananas plantains are best known as a food crop, almost every part of the plant can be used in one way or another. It is both cheap and full of nutrients are rich in nutrition, fiber, vitamins and minerals. Various parts of the banana plant itself can also be used for different purposes all over the world. In Indonesia, the banana plant is used to make traditional medicine and as animal feed. In indigenous systems of medicine, pseudostem juice is a well-known remedy for urinary disorders, stomach troubles like diarrhea, dysentery and flatulence; It helps in treatment for removal of stones in the kidney, gall bladder, and prostate. Banana leaves are used in eczema, as cool dressings for blister and burns disease. Banana flowers is used in dysentery and ulcer disease. Some of the other by products made from banana includes values added products from banana fruits like banana puree, banana powder, banana catsup, banana flour, banana chips dried banana fritter, banana vinegar, banana wine, banana jam, banana jelly sweet coat.
Defining competitivity of an absorbing Markov chain

The problem of defining the competitivity for the different states of an absorbing Markov chain is formulated in a continuous time framework. Chain states are associated with the modules of locally equilibrated, fluctuating energy levels formed due to strong adiabatic interactions within a nonequilibrium system being nonadiabatically coupled weakly to the equilibrium environment. Using a microscopic approach to the description of time evolution of the density matrix of the whole system, we first reduce the corresponding Liouville–von Neumann equation to a master equation for diagonal elements of the density matrix of a nonequilibrium system, then provide a calculus of involved chaotic and stochastic averages with the supposed initial and completed energy-level distributions, and finally arrive at the kinetic equation for the population of aggregated chain states. The equation is in detail balanced by respective transition probabilities being well defined for all the differences between energies and dimensionalities of the chain state modules. For the case of an absorbing Markov chain, this makes it possible to define the competitivity for different modular states, as an inverse slope of log odds of normalized peaks of their population with respect to log of various input transition probabilities set to be free in the wide limits.
Optimal Clustering of Products for Regression-Type and Classification-Type Predictive Modeling for Assortment Planning

In collaboration with a national retailer, this study focused on assessing the impact of sales prediction accuracy when clustering sparse demand products in various ways, while trying to identify scenarios when framing the problem as a regression-problem or classification-problem would lead to the best demand decision-support. This problem is motivated by the fact that modeling very sparse demand products is hard. Some retailers frame the prediction problem as a classification problem, where they obtain the propensity that a product will sell or not sell within a specified planning horizon, or they might model it in a regression setting that is plagued by many zeros in the response. In our study, we clustered products using k-means, SOMs, and HDBSCAN algorithms using lifecycles, failure rates, product usability, and market-type features. We found there was a consistent story behind the clusters generated, which was primarily distinguished by particular demand patterns. Next, we aggregated the clustering results into a single input feature, which led to improved prediction accuracy of the predictive models we examined. When forecasting sales, we investigated a variety of different regressionand classification-type models and report a short list of those models that performed the best in each case. Lastly, we identify certain scenarios we observed when modeling the problem as a classification problem versus a regression problem, so that our partner could be more strategic in how they use these forecasts for their assortment decision.
Shifting Boundaries: Trends in Religious and Educational Homogamy

I assess whether intermarriage between Protestants and Catholics has increased over the course of the twentieth century and, if it has, whether the declining salience of religious boundaries has been accompanied by a rising importance of educational boundaries in spouse selection. By analyzing a set of national surveys that were conducted between 1955 and 1989 and using a research design that separates the effects of period and duration of marriage, I examine changes over a longer period of time than any previous study has done. Multivariate loglinear analyses show that intermarriage between Protestants and Catholics has increased dramatically since the 1920s, while intermarriage between different educational groups has decreased. Currently, the social boundaries that separate educational groups seem to be stronger than the boundaries that separate Protestants and Catholics. In addition, there is some evidence that interfaith marriages have become increasingly homogamous with respect to education, suggesting that education has replaced religion as afactor in spouse selection.
The Relationship Between Organisational Agility and IT Alignment in Public Organisations

Three-decades long IS research suggests that Information Technology (IT) alignment is regarded as one of the pervasive issues among researchers and practitioners. Given the current dynamic business environment, organisations need to foresee external changes and make necessary adjustments (i.e., they need to be agile) while attempting to achieve and maintain IT alignment. However, the research on the two streams — IT alignment and organisational agility — seems not to overlap yet. On the other hand, the prior studies investigating the relationship between the two constructs report contradictory findings. To address the lack of knowledge about the influence of organisational agility on IT alignment in the public sector, this study presents the results of a multiple-case study conducted in four sub-city administrations in the capital of Ethiopia, Addis Ababa. The findings suggest that organisations success to reach IT alignment while aiming for organisational agility is the function of environmental volatility and stakeholder relationships.
The conditions of socioeconomic development exploring the legitimacy of social norms, trust, and corruption in Chile and Argentina

Eine zunehmende Anzahl von Forschungsarbeiten basierend auf grosen internationalen Vergleichsstudien weist einen Zusammenhang zwischen soziookonomischer Entwicklung und verschiedenen Einflussfaktoren auf. Beispielsweise spielen das Ausmas von Respekt fur soziale Normen, interpersonelles Vertrauen, der Grad des Vertrauens in behordliche Einrichtungen oder die Auswirkungen von Korruption in staatlichen Institutionen eine Rolle. Als Beitrag zu dieser Forschung vergleicht das Papier die unterschiedlichen soziookonomischen Entwicklungen in Chile und Argentinien zwischen 1983 und 2013. Im Vordergrund steht die Frage, ob die grosere soziookonomische Entwicklung, die in Chile stattgefunden hat, tatsachlich mit einer hoheren Legitimitat der Gesetzgebung, groserem Vertrauen in offentliche Institutionen, niedrigerem wahrgenommenen Korruptionsgrad und groserem interpersonellen Vertrauen in Zusammenhang zu setzen ist. Diese These wird von den Ergebnissen der vorliegenden Studie weder eindeutig bestatigt noch widerlegt. Stattdessen legen sie die Notwendigkeit nahe, mit einem differenzierten Ansatz zu untersuchen, wie diese Faktoren sich auf soziookonomischen Fortschritt auswirken und wie ihre Assoziierungen im Kontext politisch, sozial und okonomisch fluktuierender Rahmenbedingungen zu berucksichtigen sind.
SKADS Virtual Telescope : Timing relativistic binary pulsars PI

We propose to use the SKADS Virtual Telescope (SVT) for high precision timing observations of relativistic binary pulsars. These will include the presently known sample visible from a Southern-hemisphere location, as well as yet to be discovered, new systems. The new pulsars can be revealed with SVT survey, described in a separate proposal. The surveys have the potential for discovering a pulsar-black hole system which would also be timed under this programme. The proposed timing observations with the SVT will provide the best tests of General relativity in the strongfield regime and will even surpass tests of alternative theories performed in the solar system.
