Abstract:
Abstract The fundamental restructuring processes of agri-food networks in developing and emerging markets have intensified the debate on how to improve the integration of smallholders into so called modern value chains. In this context, the company-driven contract farming model and the member-based model of producer organizations are discussed by practitioners and in the scholarly literature as alternatives to traditional market systems. This study compares the models’ abilities to address economic challenges of highly fragmented and small-scale dominated agriculture on a household as well as on an aggregate level. It analyzes empirical data from the Indian floriculture sector with the global value chain approach. The study reveals that the smallholders perceive both contract farming and producer organization to be beneficial for their households’ economic risk situation, while only the producer organization has a positive effect on the households’ income. The contract farming benefits production and value chain efficiency, whereas the producer organization does not show an impact in these respects. We thus observe that the contract farming model increases value creation in the overall chain, but it does not raise the producer’s value capture; while the producer organization model does not heighten value creation in the overall chain, but it lifts the producers’ value capture. The organization’s individual capabilities determine how each model addresses the economic challenges. Overall, the author argues that contract farming and producer organizations are supplementing, not competitive, strategies and should be applied in combination.

Abstract:
AbstractThe European Union's (EU) long-standing financial support for its wine industry has been nontrivial but very difficult to estimate. The Organization for Economic Cooperation and Development's (OECD) generic producer support estimate methodology has been able to capture some of the supports, but it excludes such measures as subsidized distillation of low-quality wine, grants to promote wine generically, protection via import tariffs, and grubbing-up premiums. Nor does the OECD disaggregate EU supports to individual member countries. This article provides a new set of more complete estimates of support to EU wine producers. It also reveals how unevenly those supports are spread across EU member countries. The new estimates suggest that during 2007–2012, annual assistance amounted to approximately 700 euros per hectare of vines or 0.15 euros per liter of wine produced in the EU as measured at the winery gate. That is equivalent to a nominal rate of direct plus indirect producer assistance of approximately 20%. (JEL Classifications: F14, H25, L66, Q18)

Abstract:
Unforeseen important changes in price can present a significant risk in the market. The price fluctuation of agricultural commodities has raised concern for studying the volatility of different agricultural products. A persistent volatility in prices causes continued uncertainty in the market. Higher price volatility is to be mitigated by higher management costs and the higher cost of risk mitigation is often converted into higher producer prices. The aim of this paper is to investigate the price volatility of producer and consumer meat prices and to capture the volatility spillover along the Finnish meat supply chain. The Generalised Autoregressive Conditional Heteroskedasticity – Baba, Engle, Kraft and Kroner (GARCH-BEKK) model is applied to analyse shocks and volatilities of the prices and to estimate whether the price volatility is flowing from the first price level (producer) to the second price level (consumer), using monthly price indices. An asymmetric volatility spillover effect was detected in the poultry meat and a unidirectional, volatility spillover effect, from consumer to producer, is observed for pork prices. The findings of this study could serve as a tool for forecasting meat producer and consumer prices, which could assist the Finnish government with endorsing policy options to alleviate the price volatility impact, to protect both consumers and producers from its negative effects.

Abstract:
Technologies for capturing and transmitting data from different points in livestock value chains are developing very rapidly, and interest is growing in how best to use such technologies. While new data-capture technology comes with the promise of producers and others being more informed about a system, what usually results is large and complex datasets. A key challenge is to make use of the data or information. The present paper initially outlines the data-capture points and flow of information that occurs throughout the Australian beef cattle and meat sheep value chain. The avenues through which feedback can be delivered to commercial producers are briefly summarised, along with the value of this feedback and the factors that affect its value. Finally, practical principles for effective feedback systems are provided. While data capture is occurring throughout the value chain, the main focus of the paper is on carcass- and eating-quality feedback from processors to commercial producers. There is significant variation in the volume, nature and quality of data collected, and also the flow of information among members of the chain. Further, there appears to be an inconsistency in the levels of demand or desire for the feedback. The value of feedback ultimately depends on the producer’s ability to make better business decisions as a result of having that data or information. Increasing market specifications and compliance will result in greater profitability for the producer, as well as processor. The value of feedback also depends on several other factors, including its accuracy, its granularity, whether or not it can be connected to other data, and what options the producer has to use that information in the future. Feedback must be interpretable and enable better business decisions. The value of feedback will also increase if extended further upstream along the supply chain for genetic evaluation, provided there is enough information on genetically informed animals and their identifications can be tracked across the supply chain. For efficient feedback systems, every member in the chain needs to see value in the feedback, and there needs to be a mutual commitment and shared vision between all value-chain partners. Further, feedback must be provided in an efficient and practical manner, so as to increase the willingness of the information providers to deliver the feedback. Producers should be involved in any attempts to enhance feedback systems. Since there is variability in the needs, wants and capabilities of processors and producers, multiple dynamic and flexible feedback systems are required. An incentive to enhance feedback systems is to provide a value proposition by calculating the monetary value of the feedback to all members of the chain. Better objective measurements and Meat Standards Australia for lamb is likely to also contribute to better feedback value propositions. Communication and fostering of relationships among supply-chain members will always remain critical. While data permissions add a complication to information sharing across the chain, benefits can be gained by not only the commercial producer, but the entire industry.

Abstract:
This study aimed to construct the operational base of the educative work in health from a Marxist perspective. Reports of nursing experiences in the basic health services, published between 1988-2003, served as empirical base. The object was captured from: the participants; the action agents; the objective; health and education conceptions; and the generating necessity. The means/instruments were identified through: physical space; didactic resources; frequency of meetings; and the conception of health education. The type of evaluation; to whom it was directed; the goal to be reached and articulation between the theoretical and operational knowledge were identified in order to capture the purpose. The educative work in collective health can strengthen social groups when it becomes praxis that assumes the participant as a dialogical co-producer of the work in health.

Abstract:
Purpose At the beginning of the production year producers face a complex risk management decision environment given by risks specific to their operation, multiple crop insurance contracts and hedging opportunities. The purpose of this paper is to provide a producer-level framework for risk management decision making, focusing on the interaction between crop insurance and hedging. Design/methodology/approach The authors develop a Monte Carlo simulation model that generates a producer’s net income (NI) distribution that incorporates historical producer risk, price-yield correlation via a copula, price risk, and production costs. The authors evaluate the NI distribution through a modified Modern Portfolio Theory (MPT) decision framework. The authors use the modified MPT decision framework to explore tradeoffs between expected NI and farm ruin (defined as 1 or 5 percent expected shortfall) from different crop insurance contracts and pre-harvest hedging options. Findings Only revenue protection and the highest two levels of coverage level exist on the efficient frontier. The level of hedging on the efficient frontier ranges from 0 to 55 percent of Actual Production History. The authors find that increasing coverage level 5 percent (from 80 to 85 percent) negatively impacts the optimal hedging amount by 26 percentage points (from 35 to 9 percent). Originality/value The model provides the precise identification of financial benefits from different risk management strategies by incorporating producer-level historical yield data, using a copula to capture yield-price dependency structure and producer production cost in generating the NI distribution. This model can be applied to any producer’s characteristics and data.

Abstract:
The present study was carried out in the northeastern part of Bangladesh to investigate organochlorine pesticide (OCP) residues in and microbiological quality of dried barb (Puntius sophore). Samples were collected from both producers and retailers from December 2016 to April 2017. A control sample was also prepared in the laboratory with the same raw fish used by the producers to compare the results. Gas chromatography with electron capture detector (GC-ECD) was used to detect and quantify OCP residues. Six samples out of 27 (about 22%) were found to be contaminated with OCP residues. Among these six adulterated samples, four were from retailers and two from producers. Only aldrin was detected in four samples, and in the other two samples both aldrin + dieldrin and aldrin + endrin were detected. Aldrin was found in quantities between 0.332 and 0.967 ppm, dieldrin 0.762 ppm, and endrin 0.828 ppm. All these values were much higher than the maximum residual limit (MRL) of 0.1 ppm. Total plate count (TPC) of producer samples ranged from 5.3 ± 0.02 log cfu g−1 to 5.4 ± 0.03 log cfu g−1 and 6.2 ± 0.02 log cfu g−1 to 6.4 ± 0.02 log cfu g−1 for retailer samples and 5.0 ± 0.03 log cfu g−1 to 5.2 ± 0.04 log cfu g−1 for control samples. Fungal count ranged from 3.2 ± 0.04 log cfu g−1 to 3.5 ± 0.04 log cfu g−1, 3.4 ± 0.04 log cfu g−1 to 3.6 ± 0.03 log cfu g−1, and 2.2 ± 0.05 log cfu g−1 to 2.5 ± 0.03 log cfu g−1 for producer, retailer, and control samples, respectively. All the producer and retailer samples and one-third of the control samples were found to be contaminated with Escherichia coli, whereas Salmonella spp. were detected in amounts of 13.3% in producer samples and 20% in retailer samples and none in the control. In case of Vibrio spp., maximum count was found in retailer samples (13.3%), whereas producer and control samples showed none. The findings of the present study show that the presence of pesticides and poor microbiological quality of dried barb are alarming for consumers in Bangladesh and might cause prolonged disease and impending longstanding risk to human health.

Abstract:
Abstract We study the strategic interaction between a new good producer and a remanufacturer who use advertising campaigns to compete for a dominant share of the market for a certain good. Each firm chooses one of three possible strategies for running its advertising campaign. The two rival firms care only about capturing a dominant share of the relevant market. Hence, if a firm expects to capture dominant market share with probability p є [0, 1], then its payoff in the game we study is also p. Our analysis leads to four results. First, we provide the normal form representation of the game between the new good producer and the remanufacturer. Second, we specify the game in matrix form. Third, we indicate what happens at each stage of the elimination of strictly dominated strategies. Finally, we show that the iterated elimination of strictly dominated strategies yields a clear and unique prediction about the outcome of the advertising game.

Abstract:
During the liberalization process the UK regulatory authority introduced a behavioral remedy (through price-cap regulation) and structural remedy (through divestment series) in order to mitigate an exercise of market power and lower the influence of incumbent producers on wholesale electricity prices. We study the impact of these remedies on the dynamics of the wholesale electricity price during the peak-demand period over trading days. An extended autoregressive and autoregressive conditional heteroscedasticity (AR–ARCH) model with a novel skew generalized error distribution is used. This distribution allows one to capture the features of asymmetry, excess kurtosis, and heavy tails. The model is extended to include individual incumbent producers’ market shares and other explanatory variables reflecting seasonal patterns and regulatory regimes. We find that the structural remedy was more successful than the behavioral remedy because the effect of market share of the previously larger incumbent producer on the wholesale price is statistically insignificant. Moreover, after the second series of divestments, price volatility reduced.

Abstract:
A significant change is taking place in manufacturing company strategies around the globe. With new monitoring and service methods, new opportunities of product use and service provision emerge. The manufacturing companies once focused on mere product manufacture, now have started to provide ‘systemic solutions’, i.e. products combined with service packages, which are often referred to as Product-Service Systems (PSS). Currently, there is not a well-established feedback mechanism between service and design. The aim of this research is to develop a methodology to capture, represent, and re-use service knowledge to support product design. For the accomplishment of this aim an extensive literature review of the related themes to the research area took place. It was found that the feedback from service to design is fundamental for the enhancement of product performance; however, the existing literature in this area is not adequate. The industrial investigation led to the realisation that there is not an established mechanism in place to show how service knowledge (SK) can be used by designers. An in- depth investigation took place with the collaboration of, in total, four UK manufacturing companies. The author studied both the conceptual and detailed design, focusing on the design requirements (DR) and the design/service features (DF/SF) respectively. The first step was the capture of SK and its representation using Protégé software. Following this, at the conceptual design stage, SK can be re-used through the DR-SK tool. The two main purposes of the tool are the knowledge retrieval by designers, and the identification of gaps in SK. At the detailed design stage, designers can access SK through the DF-SK tool, and the developed knowledge templates. The SKaD framework was created, as a result of the amalgamation among the SKaD methodology, the knowledge templates, and the tools developed to link SK and DR, SF, and DF. Conclusively, the framework was applied on case studies within the pump manufacturing and aerospace industries, and its purpose (to aid designers accessing and re-using SK) was validated by experts within the collaborating organisations. As a result of this research’s findings, the service personnel can capture SK in a structured manner, which can then be re- used by product designers at both the conceptual and detailed design stage.

Thesis (S.M.)--Massachusetts Institute of Technology, System Design & Management Program, 2000.<br>Includes bibliographical references (p. 134-135).<br>Two major organizational tools, Integrated Process and Product Development (IPPD) and co-location, have been key initiatives in many corporate knowledge management and information flow strategies. The benefits of IPPD and co-location are well documented, and central to the success of these tools is the increased information flow and knowledge transfer across organizational boundaries. The fundamental knowledge management philosophy of IPPD is person-to-person tacit knowledge sharing and capture through the establishment of multi-disciplined Integrated Product Teams (IPT). Co-location of the integrated product team members has facilitated frequent informal face-to-face information flow outside of the structured meetings typical of IPPD processes. In today's global environment, the development and manufacture of large complex systems can involve hundreds, if not thousands, of geographically dispersed engineers often from different companies working on IPTs. In such an environment, the implementation of IPPD is challenging, and co-location is not feasible across the entire enterprise. The development of a comprehensive knowledge capture and information flow strategy aligned to the organizational architecture and processes involved with proper utilization of available information technologies is critical in facilitating information flow and knowledge transfer between dispersed IPTs. In this thesis we provide a case study of the knowledge capture and information flow issues that have arisen with the recent transition to the Module Center organization at Pratt & Whitney. We identify several critical enablers for efficient information flow and knowledge capture in a dispersed IPT environment by analyzing qualitative and quantitative survey data obtained at Pratt & Whitney, existing research in this area, and our own observations as participants in this environment. From this analysis, we identify key information flow and knowledge capture issues and provide recommendations for potential improvement. The Design Structures Matrix (DSM) methodology is used to understand the complex, tightly coupled information flow between the IPTs that exist at Pratt & Whitney. We build upon the previous Pratt & Whitney DSM work. The proposed DSM is not only a valuable tool identifying the information flow paths that exist between part level and system level attributes, but also can be utilized as an information technology tool to capture the content or knowledge contained in the information flow paths identified.<br>by Stephen V.

Trends for the consumption of fishery products had increased, and as a result, aquaculture has become increasingly more important in this context. The meagre (Argyrosomus regius) is one of the largest Sciaenidae. The meagre is a fish with excellent biological characteristics for aquaculture, such as tolerance to a wide range salinity and high commercial value. The muscle quality is considered very good, with high protein content and low fat content. The present work has as a goal to study the impact of the season of capture in the quality of the meagre, namely the lipid fractions (the total lipids content, the lipids classes, and the fatty acids profile). Samples from November and April were analyzed. This analysis found that the meagre is a low fat fish. The chemical composition of the meagre presents some seasonality, the lipids fractions being the composition that varies the most along the year. The values of lipid content (8.6%), EPA (3.3%), and omega3/omega6 (1.1%) were significantly higher in autumn. In April the samples had more omega3 fatty acids, like the DHA (10.3%), and the omega-6, in particular LA (19.3%).

Abstract:
Produced water presents economical and environmental challenges to oil producers. Downhole separation technology is able to separate oil or gas from produced fluid in downhole environment and injects waste water into deeper formations, thus saving energy and reducing waste emission. More than 120 downhole separation systems have been installed worldwide, but only about 60% of the installations achieved success. Most of the failures were due to the injectivity decline under the invasion of impurities in the injected water, such as suspended particles and oil droplets. A reliable model is needed to predict the reaction of reservoir permeability under the invasion of such impurities and serves as a tool to screen appropriate formations for downhole separator installations.<br>Previous experimental studies on particle-induced permeability damage reveal that high particle concentration, low fluid velocity, large particle size lead to more severe damage. The damage mechanisms are attributed to surface interception, bridging and size exclusion of particles in porous media. While for droplets, the resultant permeability decline is mostly due to surface interception. Empirical correlations with key parameters determined by core flooding data are widely applied to the simulation of permeability decline under invasion of particles and droplets. These correlations are developed based on characteristics of certain rocks and fluids, thus their applications are very restricted.<br>A more scientific method is to model the flow and capture of particulates at pore level. Reservoir rocks are porous media composed of pores of various sizes. Pore network models employ certain assumptions to imitate real porous media, and have been proved realistic in simulating fluid flow in porous media. In this study, a 2-dimensional square network model is used to simulate capture of particles and droplets in porous media. Pore bodies are represented by globes and pore throats are imitated with capillary tubes. The flow rates in the network are obtained by simultaneously solving mass balance equations at each pore body. The network model is tuned to match the porosity and permeability of a certain rock and serves as the infrastructure where the capture process takes place.<br>Particles are categorized as Brownian and non-Brownian particles according to size. For Brownian particles, diffusion is dominant and Fick’s law is applied to each pore inside the network to obtain deposition rate. For non-Brownian particles, their trajectories are mainly governed by gravity and drag force acting on them. Besides, the size of each particle is compared with the size of the pore where it is captured to determine the damage mechanism. For particles much smaller than the pore size, surface deposition is dominant and the permeability decline is gradual. For particles with sizes comparable to pore size, bridging and clogging are dominant and the permeability decline is much more severe.<br>Unlike particles, droplets can not be captured on top of each other. Accordingly, a captureequilibrium theory is proposed. Once the pore surface is covered by droplets, equilibrium is reached and droplets flow freely through porous media without being captured. The simulation on capture of oil droplets reveals that the surface wettability has significant influence on the resultant permeability damage. Most natural reservoirs are neutrally or oil wet. It is thus recommended to apply these surface conditions to future simulations.<br>The proposed model is validated with test data and reasonably good agreements are obtained. This new mechanistic model provides more insights into the capture process and greatly reduces the dependence on core flooding data.

Abstract:
Le captage du CO2 en postcombustion par absorption dans des solutions aqueuses d'amines est la technologie la plus mature pour réduire les émissions de gaz à effets de serre. Cependant, les amines utilisées sont susceptibles de réagir avec l'oxygène présent dans les fumées pour former de nouveaux composés qui peuvent être émis à l'atmosphère et avoir des conséquences sur l'environnement et la santé humaine.. L'objectif de cette thèse était donc d'identifier le maximum de produits de dégradation des amines grâce au développement de différentes techniques analytiques et d'échantillonnage, notamment pour l'analyse de la phase gaz. Ainsi plus de soixante produits issus de la dégradation de la monoéthanolamine (MEA) en pilote de captage du CO2 ont été identifiés. Une trentaine de ces produits sont nouveaux, ils sont souvent issus d'une même famille comme les pyrazines ou les oxazolines ou ils peuvent être caractérisés par l'allongement de la chaine carbonée (C2 entre deux hétéroatomes à C5).Des mécanismes basés sur des réactions d'alkylation/de désalkylation, la formation d'aldéhydes ou de cétones, l'amidification, l'aldolisation, la réaction d'Eschweiler Clarke, la formation de pyridines ont été proposés pour expliquer la formation de tous les nouveaux produits de dégradation et validés, dans la plupart des cas, en mélangeant les réactifs proposés dans le mécanisme. Finalement, il a été montré que la transposition de ces schémas réactionnels à trois autres amines (N-méthylaminoéthanolamine, 1-aminopropan-2-ol, 3-aminopropan-1-ol) a permis de prédire leurs produits de dégradation<br>The CO2 post-combustion capture with aqueous solutions of amines is the most mature technology to reduce greenhouse gases emissions. However chemical absorption is suffering from the degradation of amines mainly due to the presence of O2 in flue gases. Formed products, which could be rejected to atmosphere, may be detrimental to environment and human health. The aim of this thesis was to identify as many degradation products as possible thanks to the development of different sampling and analytical methods especially for gas phase analysis. Thus more than sixty products issued from monoethanolamaine (MEA) degradation were observed in pilot plant samples. Thirty of them are novel, they often belong to the same family as pyrazines or oxazolines, or they could be characterized by the increase of carbon chain lengths (C2 between two heteroatoms to C5).Mechanisms such as alkylation/dealkylation, aldehydes/ketones formation, amidification, aldolisation, Eschweiler Clarke, pyridines formation were proposed to explain the formation of novel products and were, most of the time, validated by mixing the reactants proposed in the mechanism. Finally, it has been shown that the transposition of these reactions to three other amines (N-methylaminoethanolamine, 1-aminopropan-2-ol, 3-aminopropan-1-ol) enabled us to predict their degradation products

Product platform and product family strategies place tremendous demands on the efficient capture, storage, and retrieval of information in the form of product data. The user’s adoption of an information management system for product families and mass customization is critical for allowing the system to perform as it ought. The following is a case study at a major modular playground equipment producer undergoing the implementation of a new graphical-based configurator for managing its mass customized products. The case study examines the proliferation of software packages to perform configuration and the flow of information in the configuration process. Next, the new configurator is evaluated on its new features to capture, store, and reuse configurations and its visual appeal. Last, the paper addresses the personal behaviors and training methods used for increasing adoption and their success.

Full text
Abstract:
A 20 kW reciprocating engine is operated using producer gas derived from a modern open top downdraft re-burn biomass gasifier that has been evaluated by rigorous laboratory performance testing over several hundred hours. The engine is operated at varying compression ratio (CR) from 11.5 to 17.0 and ignition timings from 30 to 6° before Top Centre (TC). The engine – alternator system is characterised for its performance by the simultaneous measurement of gas and airflow rates, gas composition (on-line), emission levels and power delivered. It is also instrumented to obtain the in-cylinder behaviour in the form of pressure-crank angle (p – θ) diagram to assess the thermodynamic behaviour of the engine. Three-dimensional (3-D) simulation of the flow field in the combustion chamber (involving piston-bowl arrangement) through the cycle up to the start of the combustion is used to obtain inputs on the turbulence intensity (u′) and length scale (lT) for the modelling of the flame propagation process in a zero-dimensional model (0-D) designed to predict the p – θ curve. The flame propagation and heat release processes make use of eddy entrainment and laminar burn-up model. The data on u′ extracted from the 3-D flow calculations match reasonably well with experiments till compression stroke but are in contradiction with trends close to TC. This is reasoned to be due to limitation of the k-ε model to capture transient effects due to reverse squish phenomenon. The 0-D model took into account the experimental behaviour of the u′ in the post-TC period to attempt to match the observed p – θ data over a range of CRs and ignition timing advances. While these predictions match well with the experimental data at advanced ignition timing at both higher and lower CRs, the peak pressure is under-predicted at lower ignition advances; reason are traced to increase in flame area and propagation speed due to reverse squish effect. When these are accounted in the model, the p – θ curves are predicted better.

Abstract:
Abstract In today’s pressing quest of emission and pollution reduction in all energy sectors, research on renewable and sustainable fuels is a key component. The Institute of Combustion Technology at the German Aerospace Center strives to assess new, renewable fuel in a gear wheel approach of interdependent linked experiments, database comparison and model-based assessment, allowing for a fast iterative feedback to the fuel producer and giving a detailed valuation of fuels as well as a distinguished preselection when presented with numerous fuel samples. Synthetic fuels as a substitute for fossil fuels are becoming increasingly important within the framework global climate protection goals. Power-to-X technologies such as Fischer-Tropsch synthesis can be used to produce carbon-neutral fuels using carbon dioxide from air (direct air capture) and hydrogen obtained by water electrolysis using green electricity. This fuel assessment has been iteratively performed for the post-processing of a Fischer-Tropsch fuel, produced in the module-based, compact and highly innovative PtL plant erected by INERATEC GmbH. The aim of the present work was to evaluate the postprocessing steps hydration and distillation of the crude Fischer-Tropsch products with hindsight to “fit-for-purpose” properties of the resulting products for aviation. The chemical composition was determined using comprehensive two-dimensional GCxGC chromatography. Numerical blending analysis was performed utilizing the DLR SimFuel platform to evaluate the range of blending ratios of the Fischer-Tropsch fuels with conventional jet fuels. It could be demonstrated that the post-processed Fischer-Tropsch fuels display a beneficially high blending potential with conventional jet fuels considering the chemical composition and combustion behavior.

Abstract:
In order to reduce the amount of carbon dioxide (CO2) greenhouse gases released into the atmosphere, significant consideration has been given to the sequestration of CO2 from power plants and other major producers of greenhouse gas emissions. Integrated Gasification Combined Cycle (IGCC) power plants offer an alternative to pulverized coal plants because the carbon dioxide may be separated from the process gas stream prior to combustion. The compression of the captured carbon dioxide stream requires a sizeable amount of power, which impacts plant availability, capital expenditures and operational cost. Preliminary analysis has estimated that the CO2 compression process reduces the plant efficiency by 8% to 12% for a typical IGCC plant. The detailed thermodynamic analysis presented here examines methods to minimize the power penalty to the producer through integrated, low-power compression concepts. The goal of the present research is to reduce this penalty through novel compression concepts and integration with existing IGCC processes. The research supports the U.S. Department of Energy (DOE) National Energy Technology Laboratory (NETL) objectives of reducing the energy requirements for carbon capture and sequestration in electrical power production. The primary objective of this study is to boost the pressure of CO2 to pipeline pressures with the minimal amount of energy required. Fundamental thermodynamic analysis methods related to the compression of CO2 are used in the following paper to explore pressure and enthalpy rise in both liquid and gaseous states.

Full text
Abstract:
Fluidized beds can be used to gasify biomass in the production of producer gas, a flammable gas that can replace natural gas in process heating. Modeling these reactors with computational fluid dynamics (CFD) simulations is advantageous when performing parametric studies for design and scale-up. From a computational resource point of view, two-dimensional simulations are easier to perform than three-dimensional simulations, but they may not capture the proper physics. This paper will compare two- and three-dimensional simulations in a 10.2 cm diameter fluidized bed with side air injection to determine when two-dimensional simulations are adequate to capture the bed hydrodynamics. Simulations will be completed in a glass bead fluidized bed operating at 1.5Umf and 3Umf, where Umf is the minimum fluidization velocity. Side air injection is also simulated to model biomass injection for gasification applications. The simulations are compared to experimentally obtained time-averaged local gas holdup values using X-ray computed tomography. Results indicate that for the conditions of this study, two-dimensional simulations qualitatively predict the correct hydrodynamics and gas holdup trends that are observed experimentally for a limited range of fluidization conditions.

Abstract:
Besides oil, coffee is one of the most traded commodities worldwide. Colombia is known as the producer of the highest quality coffee in the world, thanks to its smooth taste and aroma. One of the key elements that are responsible for the quality of Colombian coffee is its harvesting method, in which it is enforced that only mature fruits are harvested. Given the terrain conditions in which coffee trees grow, the preferred harvesting method in Colombia is selective hand picking, in which each coffee grain is individually teared off from the branch that is attached to. This work focuses on the analysis of the motion of a human hand performing the action of manual selective coffee harvesting. The analysis is based on the data collected from a custom made motion capture system, which consists of a glove capable of sensing the angular movement of the joints, and accelerations at the tip of the fingers, by means of a set of flex sensors and accelerometers, respectively. The methods followed in this investigation include the study of the biomechanics of the hand, as applied to the motion of hand picking of coffee, which proved to be fundamental for the analysis of the experimentally measured data. After processing the experimental data, the patterns of movement done by a human coffee harvester can be simulated and replicated, which allows identifying trajectories that a good harvester follows, as compared to other harvesters, which collect smaller amounts of grains during the same period of time. After having parameterized the motion of efficient selective hand picking, the results from this investigation serve as the basis for the design and optimization of an electromechanical tool to assist in the process of coffee harvesting, which minimizes the amount of green beans removed from the branches of the coffee trees.

Abstract One of Allen-Bradley’s goals is leveraging — taking better advantage of existing resources. We are developing a methodology and supporting tools that help engineers share and reuse (i.e., leverage) their firmware design and development work. Writing reusable firmware source code is especially difficult due to the tight constraints in most embedded systems — code must usually be written for product specific hardware needs and resources. Reuse of engineering work at the design level is a more effective approach. With this in mind, we have been working with Allen-Bradley Power Products engineers and managers to pilot a Firmware Design Capture (FDC) system. In a FDC system, engineers work in their own paper or electronic workbooks compiling descriptions of their domains’ technologies and algorithms in loosely structured electronic document sets called technology books. Product-specific information is placed in complementary document sets called product books. Engineers can access this growing body of ‘Strategic Design Information’ that they and others have created; freely drawing from, commenting on, or adding to it. Key characteristics of this FDC system are: • A focus on collecting reusable and accessible design information • Incremental, small-grained development of documents during design activity • Electronic format of documents, for ease of refinement and access • Unobtrusive tools and methods, determined through frequent user feedback We expect this methodology to help engineers improve schedule predictability and reduce the firmware development life cycle, better retain vital technologies and product data, and increase product quality. Feedback from our initial work supports these expectations.

Abstract:
ABSTRACT An optimized completion design that addresses gaps in the existing single well Producer-Injector (P-I) concept is presented in this paper. Field development scenarios based on the optimized P-I concept and conventional waterflood were implemented in full-field 3D simulation models. Detailed review of the existing single P-I well concept revealed gaps in the completion design with regards to feasibility of data acquisition, ease of well intervention and well safety/control. The existing design utilizes a Single-String-Single (SSS) design with through-tubing water injection and oil production through annulus, whilst the optimized design is a Two-String-Dual (TSD) incorporating the flexibility of independent injection/production, zonal isolation for interventions &amp; data acquisition and additional safety completion jewelries. A fit-for-purpose reservoir candidate was selected by assessing it's suitability to waterflooding. The reservoir belongs to the paralic sequence of the Agbada Formation of the Niger Delta basin – a sequence of interbedded sandstones and shales. The reservoir is an elongated anticline bounded by W-E oriented faults and exhibiting channelized shoreface sediments. Porosity and permeability ranges are 17-31% and 200mD-2200mD respectively. Shale baffles strongly reduces the influence of the aquifer hence the simulation model is an oil reservoir with weak aquifer completed by the P-I well producing oil and injecting into the aquifer in tandem. Performance of the single P-I well strategy was benchmarked against conventional waterflood patterns to effectively capture the recovery efficiency and production forecast for each scenario. Results from the five-parameter experimental design based on the P-I strategy, indicate Ultimate Oil Recovery is most impacted by horizontal permeability; injection rate, flow barrier transmissibility and vertical permeability with the least influence. Dynamic 3D water saturation maps show the waterflood front propagating principally in the horizontal direction from the injector, providing important reservoir boundary pressure support and minimizing the chance for injected water short-circuiting at the sandface. Ultimate Oil Recovery of 5spot/line drive patterns and the P-I strategy were similar, 54% and 52% respectively. Well completion costs and forecasts were fed into simple economics spreadsheet to test which technique provides the most value. Open book economics results showed the P-I concept provides better value (NPV 23.0 and VIR 0.67) than 5 spot and line drive patterns (NPV-17 and VIR-0.14).

Abstract This paper reports research on approaches for accessing and controlling product data within the Product Introduction Process (PIP) through the specification, prototyping, and integration of a set of product structures, product viewpoints and their relationships. A significant achievement has been the validation of a collection of computer-based models of product structures that enable the capture of work breakdown, product specification, product functionality, and the physical parts that comprise the product. Furthermore, a number of relationships between these product structures and the business processes that use and create them have been identified. The work presented in this paper demonstrates the importance of representing relationships between product introduction processes and products through the adoption of product structures. The potential for exploiting product structures to improve understanding of relationships between products and processes is illustrated. A case study captures flows of related functional and physical product structures within PIPs across a two-tier supply chain, and discusses the issues involved in supporting such related product and process information.

Abstract:
As a result of increased concern over Greenhouse Gas emissions, capture of CO2 from stationary power sources is a topic under discussion throughout the world. The most developed technology for the application is post combustion carbon capture using liquid solvents. However, due to very low concentration of CO2 in the gas turbine emitted flue gas, energy penalty caused by the capture process is relatively high. One of the methods to increase CO2 concentration is the recycling of flue gas (also termed as EGR) in which part of the flue gas is sent back to join the air stream entering the compressor. This paper presents results of an experimental campaign carried out at the Pilot Scale Advanced Capture Technology (PACT) facilities of the UK Carbon Capture and Storage Research Centre (UKCCSRC). A Turbec T100 microturbine of 100kWe is integrated with a post combustion carbon capture plant of 1TPD (Ton per day) CO2 capture capacity. The microturbine is very lean combustion system and produces a flue gas having only 1.5% CO2. Therefore, in order to simulate EGR on industrial gas turbines which produce around 4–5% CO2 in the exhaust stream, CO2 from a cryogenic storage tank was injected into the slip stream of the gas turbine exhaust. The impact of different CO2 concentrations (representing EGR) on the post combustion carbon capture process is experimentally evaluated. It is observed that the energy penalty caused by the capture process is considerably reduced at higher CO2 concentration in the absorber inlet flue gas stream. EGR also has a negative impact on the produced power from the gas turbine as well as the combustion process. However, it has positive impact on the power output from steam turbine. Optimum recycle ratio for maximum power output from combined cycle gas turbine is discussed. Performance of the absorption column as indicated by rich and lean solvent CO2 loadings is discussed. Moreover, emissions of solvent and some of the degradation products with the exhaust gas from the capture plant are monitored and reported.

Abstract:
Why do some fuel protests in Nigeria lead to a response from government, but others are barely noticed? What are the politics behind government response and who are the winners and losers? Using a multi-method approach, this study focuses on the period between 2007 and 2017 to investigate the dynamics of fuel protest in Nigeria to ask how, and under which conditions, struggles over energy access in Nigeria produce accountability and empowerment. The findings suggest that accountability and empowerment outcomes of the struggles over fuel access in Nigeria are severely limited by the very conditions that define the state as fragile: weak institutions, elite capture, widespread corruption, and a citizenry that is protest-fatigued and disempowered. This could be true of other fragile and conflict-affected settings. Therefore, frameworks that open up the civic space for dialogues between the government and citizens may produce better outcomes than protests.

Abstract:
Background: Major depressive disorder is a common mental disorder. Many pressing questions regarding depression treatment and outcomes exist, and new, efficient research approaches are necessary to address them. The primary objective of this project is to demonstrate the feasibility and value of capturing the harmonized depression outcome measures in the clinical workflow and submitting these data to different registries. Secondary objectives include demonstrating the feasibility of using these data for patient-centered outcomes research and developing a toolkit to support registries interested in sharing data with external researchers. Methods: The harmonized outcome measures for depression were developed through a multi-stakeholder, consensus-based process supported by AHRQ. For this implementation effort, the PRIME Registry, sponsored by the American Board of Family Medicine, and PsychPRO, sponsored by the American Psychiatric Association, each recruited 10 pilot sites from existing registry sites, added the harmonized measures to the registry platform, and submitted the project for institutional review board review Results: The process of preparing each registry to calculate the harmonized measures produced three major findings. First, some clarifications were necessary to make the harmonized definitions operational. Second, some data necessary for the measures are not routinely captured in structured form (e.g., PHQ-9 item 9, adverse events, suicide ideation and behavior, and mortality data). Finally, capture of the PHQ-9 requires operational and technical modifications. The next phase of this project will focus collection of the baseline and follow-up PHQ-9s, as well as other supporting clinical documentation. In parallel to the data collection process, the project team will examine the feasibility of using natural language processing to extract information on PHQ-9 scores, adverse events, and suicidal behaviors from unstructured data. Conclusion: This pilot project represents the first practical implementation of the harmonized outcome measures for depression. Initial results indicate that it is feasible to calculate the measures within the two patient registries, although some challenges were encountered related to the harmonized definition specifications, the availability of the necessary data, and the clinical workflow for collecting the PHQ-9. The ongoing data collection period, combined with an evaluation of the utility of natural language processing for these measures, will produce more information about the practical challenges, value, and burden of using the harmonized measures in the primary care and mental health setting. These findings will be useful to inform future implementations of the harmonized depression outcome measures.
