Production riser  

SciTech Connect

A riser is described for production of oil and gas in a marine location with the riser connected to the casing supported at the mud line of a body of water and extending upward in the water to a tension moored floating structure. The riser includes a flexible joint near its connection to the casing and is supported at its upper end from the floating structure and is also supported from the floating structure at a point between 50 and 175 feet below the water level. A production string extends upwardly from the producing zone through the casing, the flexible joint and the riser to the floating structure and wellhead equipment is supported on such riser. Centralizers are provided for the production string with the centralizer immediately above the flexible joint being between 35 to 65% of the total distance between such centralizer and the centralizer positioned immediately below the flexible joint.

Bottom production  

SciTech Connect

In the context of the LHC experiments, the physics of bottom flavoured hadrons enters in different contexts. It can be used for QCD tests, it affects the possibilities of B decays studies, and it is an important source of background for several processes of interest. The physics of b production at hadron colliders has a rather long story, dating back to its first observation in the UA1 experiment. Subsequently, b production has been studied at the Tevatron. Besides the transverse momentum spectrum of a single b, it has also become possible, in recent time, to study correlations in the production characteristics of the b and the b. At the LHC new opportunities will be offered by the high statistics and the high energy reach. One expects to be able to study the transverse momentum spectrum at higher transverse momenta, and also to exploit the large statistics to perform more accurate studies of correlations.

Novolak Production  

NASA Astrophysics Data System (ADS)

Novolak resins are produced by reacting formaldehyde (30-55% concentration) with phenol under acidic conditions, with oxalic acid as the preferred catalyst and in special conditions, sulfuric acid. Depending on the batch size, all raw material components can be introduced into the reactor, or when there is an increase in the batch size as well as in the reactor volume, the reaction exotherm is controlled by a gradual addition of formaldehyde. Modern novolak production facilities are automated and programmed for reduced operational cost. A flow diagram of a general production line for the manufacture of novolak is shown. Recovery of the novolak is accomplished by the removal of water and devolatilization of crude novolak to molten, low-free phenol novolak resin which can be isolated as flake or pastille or dissolved in appropriate solvents. Novolak is stored either in a solid flake or pastille form or in solution. Most production is conducted under atmospheric conditions, but there are some recent, novel activities such as pressure in a hermetically-closed reactor reaching 0.1-10 MPa by using the heat of reaction without reflux to shorten reaction time, accelerating dehydration time by flash distillation, and providing economic benefit in the cost of novolak production.

The empirical results indicate that (i) the nonmilitary public capital stock is dramatically more important in determining productivity than is either the flow of nonmilitary or military spending, (ii) military capital bears little relation to productivity, and (iii) a 'core' infrastructure of streets, highways, airports,

Urban Economies and Productivity  

Microsoft Academic Search

Productivity levels and productivity growth rates vary significantly over space. These differences are perhaps most pronounced between countries, but they remain acutely evident within national spaces as economic growth favors some cities and regions and not others. In this paper, we map the spatial variation in productivity levels across Canadian cities and we model the underlying determinants of that variation.

Petroleum production systems  

SciTech Connect

Petroleum production engineering attempts to maximize production in two connected systems, the reservoir and the artificial structures related to a well field. Determining whether it is economically feasible to drill a discovered source requires a familiarity with a variety of topics and theories. This book devotes the first six chapters to these concepts, including production from undersaturated oil reserves, production from two-phase reservoirs, production from natural gas reservoirs, skin effects, and gravel pack completions. The second part of the production engineer`s mission is maximization of output in the artificial structures, which include the well, bottomhole, and wellhead assemblies, and the surface gathering, separation, and storage facilities. This general system is discussed throughout the remainder of the book. Chapter topics include wellbore flow performance, forecast of well production, well test design and data acquisition, matrix acidizing, hydraulic fracturing for well simulation, gas lift, and systems analysis.

Fermentative production of isobutene.  

PubMed

Isobutene (2-methylpropene) is one of those chemicals for which bio-based production might replace the petrochemical production in the future. Currently, more than 10 million metric tons of isobutene are produced on a yearly basis. Even though bio-based production might also be achieved through chemocatalytic or thermochemical methods, this review focuses on fermentative routes from sugars. Although biological isobutene formation is known since the 1970s, extensive metabolic engineering is required to achieve economically viable yields and productivities. Two recent metabolic engineering developments may enable anaerobic production close to the theoretical stoichiometry of 1isobutene + 2CO(2) + 2H(2)O per mol of glucose. One relies on the conversion of 3-hydroxyisovalerate to isobutene as a side activity of mevalonate diphosphate decarboxylase and the other on isobutanol dehydration as a side activity of engineered oleate hydratase. The latter resembles the fermentative production of isobutanol followed by isobutanol recovery and chemocatalytic dehydration. The advantage of a completely biological route is that not isobutanol, but instead gaseous isobutene is recovered from the fermenter together with CO(2). The low aqueous solubility of isobutene might also minimize product toxicity to the microorganisms. Although developments are at their infancy, the potential of a large scale fermentative isobutene production process is assessed. The production costs estimate is 0.9 Euro kg(-1), which is reasonably competitive. About 70% of the production costs will be due to the costs of lignocellulose hydrolysate, which seems to be a preferred feedstock. PMID:22234536

Infrastructure for microsystem production  

NASA Astrophysics Data System (ADS)

Manufacturing of micro-systems differs from IC manufacturing because the market requires a diversity of products and lower volumes per product. In addition, a diversity of micro-technologies has been developed, including non-IC compatible processes and potentially IC compatible processes. An infrastructure for the production of micro- system devices is lacking. On one side the technology for MST is available at the universities and small university related companies. On the other side there are several small and medium enterprises and bigger companies wanting to implement MST devices in their products, but unwilling to be dependent on universities. Philips Electronics in the Netherlands and Twente MicroProducts realized this problem and have started a project to fill this gap. At this moment the basic of the infrastructure is available: OnStream BV, Eindhoven, The Netherlands, opened its waferfab and assembly facilities for the production of MST devices. Twente MicroProducts will take care of the design of the products and of the small-scale production. Integration of quality systems for maintenance, yield, statistical process control and production in a Manufacturing Execution System offers direct access for all people involved to all the relevant information. It also ensures quality of the products made. The available capabilities of the infrastructure in the current status are compared to the market needs. In this article, a description of a seamless Micro-System Engineering Foundry is given. A seamless organization is capable of helping the customer from design to production. Several examples are given.

Packaging and integration processes have lagged behind MEMS research but are rapidly maturing. As packaging processes evolve, a new challenge presents itself, microsystem product development. Product development entails the maturation of the design and all the processes needed to successfully produce a product. Elements such as tooling design, fixtures, gages, testers, inspection, work instructions, process planning, etc., are often overlooked as MEMS engineers concentrate on design, fabrication and packaging processes. Thorough, up-front planning of product development efforts is crucial to the success of any project.

The underlying parton dynamics is investigated by studying the transverse momentum distribution of charged particles and comparing the measurements with various Monte Carlo generators using different approaches to simulate the parton cascade. In this context also results on forward jet production are discussed. The underlying parton dynamics is also studied using prompt photon production in both DIS and photoproduction regimes. The production is compared to theoretical calculations and Monte Carlo predictions. In the context of hadronisation, studies are presented of the scaled momentum distribution for charged hadrons and for KS0 and ? particles in the current fragmentation region of the Breit frame. The data are compared to models and to next-to-leading order QCD calculations. In addition, differential cross sections for KS0 production in the laboratory and Breit frame are investigated and compared to Monte Carlo predictions, which are used to study the flavour decomposition and strangeness suppression factor. KS0 production is also compared to the production of charged particles and to the production rate of the DIS events.

Reputation and Product Quality  

Microsoft Academic Search

This article considers the role that reputation plays in assuring product quality in markets where consumers can only imperfectly judge product quality even after consumption. Three conclusions are derived. First, high quality firms have more customers because they have fewer dissatisfied customers who leave and word-of-mouth advertising results in more arrivals. Second, higher fixed costs can result in a higher

The MACC Fire Products  

NASA Astrophysics Data System (ADS)

This presentation gives an overview of the global fire emission monitoring products that have so far been developed in the projects GEMS "Global and regional Earth-system (Atmosphere) Monitoring using Satellite and in-situ data" and MACC "Monitoring Atmospheric Composition and Climate". The products are available either in real time with a time lag of about six hours or retrospectively starting in 2003. One line of products is based on the "Global Fire Emissions Database" (GFED) inventory. Another is based on satellite-based fire radiative power (FRP) observations that are routinely available in real time. The FRP products that are based on the geostationary Meteosat-9 observations, which are produced at the EUMETSAT LandSAF, resolve the diurnal variation of open fires in Africa and Southern Europe. The FRP products derived by MACC from geostationary GOES observations do the same for the Americas. The FRP products derived by NASA/NOAA from the polar orbiting MODIS observations provide complementary global coverage in roughly one day and serve as transfer standard between the different geostationary observations. All FRP products are merged in MACC to provide a consistent global map of fire activity, from which emission rates of various species are derived. The emission rates are subsequently used as lower boundary conditions for the atmospheric composition modeling in other parts of MACC. The products are also available to the public.

Primary Productivity: Marine Adaptation  

NSDL National Science Digital Library

This activity is designed to give students a better understanding of the concept of primary productivity and to have them use one or more methods to calculate primary productivity. Students will have also been introduced to the concepts of marine primary productivity, net productivity vs. gross productivity, and the importance of comparing dry weight versus wet weight. Marine primary producers are usually not plants as we typically think about them, but rather seaweeds or single cell algae. The classic example of a marine primary producer is a marine diatom. In this experiment students use marine diatoms to measure primary productivity. Real-time data from several sources may be used to increase understanding of this topic. Students will discover that although often ignored in the classroom, the marine environment produces 32 percent of the world's primary productivity on 71 percent of the Earth's surface area. Although this is far less than the 68 percent from the continental surfaces (29 percent of the Earth's surface area), this productivity is still very important.

Concrete production floating platforms  

SciTech Connect

The floating production platforms operating in the North Sea are adapted from drilling semisubmersibles which allow only a limited payload capacity. Experience of concrete production platforms constructed for the North Sea has led Sea Tank Co. to propose a floating platform which offers large payload and oil storage capacities similar to those of existing fixed platforms. Sea Tank Co. and Institut Francais du Petrole joined forces in early 1976 to study the feasibility of a concrete floating production platform incorporating the structure and the production riser together. The results of this 3-yr program show that the concrete floating structure is economically attractive for permanent utilization on a production site. Furthermore, concrete has definite advantages over other materials, in its long term behavior.

Simplified subsea production wellhead  

SciTech Connect

A simplified subsea production wellhead which permits (1) pumpdown tool operations for routine well maintenance and (2) vertical entry to the wellbore for major workover operations. The wellhead can be lowered by the production pipeline to a wellhead site on the sea floor. The production wellhead includes a diverter spool for releasably attaching to a subsea well. Pumpdown tools can be used with the diverter spool. If vertical entry of the subsea well is required, the diverter spool can be released, raised and moved horizontally to one side of the subsea well, giving vertical entry. After workover operations, the diverter spool is again moved over the subsea well and reattached.

Lyophilization of biotechnology products.  

PubMed

In this review the lyophilization of biotechnology products is discussed. It is emphasized that the final quality of a protein product is determined by an interplay between the proper choice of excipients and the freeze-drying process. A crystalline matrix after freeze-drying is detrimental for the protein product. A glassy amorphous state is a prerequisite for stability, however a glassy state as such will not assure sufficient stability. The glass temperature which defines the state of the freeze-dried cake can be influenced by the moisture content and the choice of excipients. PMID:7850454

Modified product cubature formulae  

NASA Astrophysics Data System (ADS)

In the univariate case, there is a well-developed theory on the error estimation of the quadrature formulae for integrands from the Sobolev classes of functions. It is based on the Peano kernel representation of linear functionals, which yields sharp error bounds for the quadrature remainder. The product cubature formulae are the usual tool for the approximation of a double integral over a rectangular domain. In this paper we suggest a modification of the product cubature formulae, based on blending interpolation of bivariate functions. Besides the usual point evaluations, the modified cubature formulae involve few line integrals. Our approach allows application of the Peano kernel theory for derivation of error bounds for both standard cubature formulae and their modifications. Sufficient conditions for the definiteness of the modified product cubature formulae are given, and some classes of integrands are specified, for which a product cubature formula is inferior to its modified version.

Cancer immunotherapy products  

PubMed Central

Active immunotherapy products (widely known as “cancer vaccines”) are products intended to stimulate an immune response to mediate tumor destruction or reduce the progression of disease in patients where cancer has been diagnosed. Some quality attributes of these products are very difficult to characterize or present a high variability (especially if they are for autologous use), further complicating the interpretation of some of the clinical data. Furthermore, questions arise in the evaluation of efficacy and safety data in comparison with current chemical or biological treatments for the same indications. Some of these aspects are discussed in this paper in relationship with the regulatory requirements in the European Union and as applied to two recently assessed medicinal products, Oncophage and Provenge, both considered therapeutic “cancer vaccines” for renal cell carcinoma and prostate cancer, respectively.

Material and Energy Productivity  

PubMed Central

Resource productivity, measured as GDP output per resource input, is a widespread sustainability indicator combining economic and environmental information. Resource productivity is ubiquitous, from the IPAT identity to the analysis of dematerialization trends and policy goals. High resource productivity is interpreted as the sign of a resource-efficient, and hence more sustainable, economy. Its inverse, resource intensity (resource per GDP) has the reverse behavior, with higher values indicating environmentally inefficient economies. In this study, we investigate the global systematic relationship between material, energy and carbon productivities, and economic activity. We demonstrate that different types of materials and energy exhibit fundamentally different behaviors, depending on their international income elasticities of consumption. Biomass is completely inelastic, whereas fossil fuels tend to scale proportionally with income. Total materials or energy, as aggregates, have intermediate behavior, depending on the share of fossil fuels and other elastic resources. We show that a small inelastic share is sufficient for the total resource productivity to be significantly correlated with income. Our analysis calls into question the interpretation of resource productivity as a sustainability indicator. We conclude with suggestions for potential alternatives.

Exergy and productivity  

SciTech Connect

With the fates of entire industries in the balance in the world's competitive economic battlegrounds, the leading competitor will be the one that is most productive in its sphere of competition. Conservation and competition are unnatural bedfellows. The most adept competitors will use the best principles of productive scientific management to seek the path of least action (Hamilton's principle) and least time (Fermat's principle) to triumph over their competitors' incomplete and insufficient conceptions of management. Exergy management can work in productive synergy with sound economic principles and other valid productivity principles to define and decide on optimal paths for a corporation to follow within existing degrees of freedom. It has identified its AEU and found its proper economics--exergioeconomics. It will encourage other managements to identify, say, their APUs (American Productivity Units) and their proper economics. When other managements follow suit, the revivified corporate entity will be admirably qualified to compete in the marketplace and reap the rewards that production economics offers through optimum allocation and utilization of energy, labor, capital and materials.

Dairy products and cancer.  

PubMed

Cancer is a group of more than 100 diseases in which cells display uncontrolled growth, invasion, and sometimes metastasis. Milk and dairy products contain micronutrients and several bioactive constituents that may influence cancer risk and progression. Much of the focus of human, population-based studies has been on the effects of intake of milk and total dairy products or of calcium intake. Based on a systematic review of the epidemiologic literature, the World Cancer Research Fund and American Institute for Cancer Research report concluded there was a probable association between milk intake and lower risk of colorectal cancer, a probable association between diets high in calcium and increased risk of prostate cancer, and limited evidence of an association between milk intake and lower risk of bladder cancer. For other cancers, the evidence was mixed or lacking. Since the 2007 report, several additional, large-cohort studies have been published, including two that show an inverse association between intake of cultured dairy products and bladder cancer. Little is known about the potential effect of various bioactives produced during rumen microbe metabolism on cancer risk. Furthermore, studies support a role of live microbes present in some dairy products in the modulation of the human gut microbial community and gut metabolism. Given the growing appreciation for the role of the gut microbial community in relation to immune function and health and disease, including cancer, the potential role of various dairy products in the modulation of the human gut microbiome warrants further evaluation. Key teaching points: As a dietary exposure, dairy products are a complex group of foods and composition varies by region, which makes evaluation of their association with disease risk difficult. For most cancers, associations between cancer risk and intake of milk and dairy products have been examined only in a small number of cohort studies, and data are inconsistent or lacking. Meta-analyses of cohort data available to date support an inverse association between milk intake and risk of colorectal and bladder cancer and a positive association between diets high in calcium and risk of prostate cancer. Other constituents of dairy products, such as rumen-derived metabolites, have not been evaluated extensively for cancer-preventive properties. The influence of live microbes in fermented dairy products and certain cheeses on the human gut microbiome and immune function is a growing area of study. PMID:22081693

Beauty production at CDF  

SciTech Connect

A review of recent measurements of beauty production, based on proton antiproton collision data at {radical}s = 1.96 TeV and using the CDF detector, is given. Previous measurements of beauty (b) quark production at the Tevatron, carried out at centre-of-mass energies {radical}s = 1.8 TeV, have shown discrepancies when compared to Next to Leading Order (NLO) predictions [1]. Improved predictions and experimental procedures have reduced this discrepancy [2]. Improved parton density functions, better fragmentation functions and more complete theoretical calculations have improved theoretical accuracy. Experimentally, measurements of beauty production at {radical}s = 1.96 TeV are now presented in terms of b hadrons or B mesons, to avoid problems unfolding back to the quark level. In this review [3] measurements of inclusive beauty (where one beauty jet or hadron is reconstructed in the event), and beauty + X (where X can be a boson or another beauty jet or hadron), production will be presented: inclusive beauty jet cross-section; semi and fully reconstructed B meson cross-section; beauty dijet cross-section; semi-reconstructed B B meson cross-section; Z boson + beauty jet cross-section. More information concerning other measurements of heavy quark production can be found elsewhere [4].

SAR Product Control Software  

NASA Astrophysics Data System (ADS)

As SAR instruments and their operating modes become more complex, as new applications place more and more demands on image quality and as our understanding of their imperfections becomes more sophisticated, there is increasing recognition that SAR data quality has to be controlled more completely to keep pace. The SAR product CONtrol software (SARCON) is a comprehensive SAR product control software suite tailored to the latest generation of SAR sensors. SARCON profits from the most up-to-date thinking on SAR image performance derived from other spaceborne and airborne SAR projects and is based on the newest applications. This paper gives an overview of the structure and the features of this new software tool, which is a product of a co-operation between teams at BAE SYSTEMS Advanced Technology Centre and DLR under contract to ESA (ESRIN). Work on SARCON began in 1999 and is continuing.

The Pareto index is found to decrease with the level of aggregation, i.e., from workers to firms and to industrial sectors. In order to explain these phenomenological laws, we propose a superstatistics framework, where the role of the fluctuating temperature is played by the fluctuating demand.

Productivity increases in science  

SciTech Connect

The study quantifies the impact on the cost of experimentation of synergistic advancements in instrumentation, theory, and computation over the last two decades. The study finds that the productivity of experimental investigation (experimental results/$) is increasing as science is transformed from a linear, isolated approach to a hierarchical, multidisciplinary approach. Developments such as massively parallel processors coupled with instrumental systems with multiple probes and diverse data analysis capabilities will further this transformation and increase the productivity of scientific studies. The complexities and scale of today`s scientific challenges are much greater than in the past, however, so that the costs of research are increasing. Even though science is much more productive in terms of the experimental results, the challenges facing scientific investigators are increasing at an even faster pace. New approaches to infrastructure investments must capitalize on the changing dynamics of research and allow the scientific community to maximize gains in productivity so that complex problems can be attacked cost-effectively. Research strategies that include user facilities and coordinated experimental, computational, and theoretical research are needed.

Glutathione Production in Yeast  

NASA Astrophysics Data System (ADS)

Glutathione, ? -glutamyl-cysteinyl-glycine, is the most abundant non-protein thiol found in almost all eukaryotic cells (and in some prokaryotes). The tripeptide, which is synthesized non-ribosomally by the consecutive action of two soluble enzymes, is needed for carrying out numerous functions in the cell, most important of which is the maintenance of the redox buffer. The cycle of glutathione biosynthesis and degradation forms part of the ? -glutamyl cycle in most organisms although the latter half of the pathway has not been demonstrated in yeasts. Our current understanding of how glutathione levels are controlled at different levels in the cell is described. Several different routes and processes have been attempted to increase commercial production of glutathione using both yeast and bacteria. In this article we discuss the history of glutathione production in yeast. The current bottlenecks for increased glutathione production are presented based on our current understanding of the regulation of glutathione homeostasis, and possible strategies for overcoming these limitations for further enhancing and improving glutathione production are discussed

Strangeness production in ALICE  

NASA Astrophysics Data System (ADS)

The ALICE experiment at the LHC has measured the production of strange and multi-strange hadrons both in Pb–Pb and pp collisions at unprecedented beam energies. Transverse momentum spectra at mid-rapidity for K0S mesons, ?, and ?? baryons and their anti-particles in Pb–Pb collisions at TeV are presented in different centrality intervals. Particles are reconstructed via their weak decay topologies into charged particles only over a wide momentum range, exploiting the tracking and particle identification capabilities of the ALICE detector. The corresponding production yields are compared with those observed in pp collisions and lower energy heavy-ion reactions. In particular, results on baryon-to-meson ratio, strangeness enhancements, elliptic flow and nuclear modification factors are discussed. The comparison of strange particle spectra in pp collisions at TeV with PYTHIA Perugia-2011 predictions is also presented.

This paper reports that the growing use of heavy crude is making delayed coking more important for increased liquid yields. More cokers are being designed to operate in low pressure and ultra low recycle. The type of projects executed include: traditional revamps for heavy feeds, maximum liquid yield greenfield cokers, true zero recycle-single pass cokers (as opposed to an ultra low recycle coker) and units designed for flexibility in product yield distribution. Although delayed coking has been around since the mid-30-s, the current engineering innovations in design and operation of these units by Foster Wheeler focus on the following: increased fuel coke production, paying greater attention to crude desalting operations, reviewing the impacts of vacuum unit outpoint and preprocessing of feeds, operations involving longer heater run lengths, shorter operating cycles and increased automation, safety and environmental concerns.

Sustainable Multi-Product Seafood Production Planning Under Uncertainty  

NASA Astrophysics Data System (ADS)

A multi-product fish production planning produces simultaneously multi fish products from several classes of raw resources. The goal in sustainable production planning is to meet customer demand over a fixed time horizon divided into planning periods by optimizing the tradeoff between economic objectives such as production cost, waste processed cost, and customer satisfaction level. The major decisions are production and inventory levels for each product and the number of workforce in each planning period. In this paper we consider the management of small scale traditional business at North Sumatera Province which performs processing fish into several local seafood products. The inherent uncertainty of data (e.g. demand, fish availability), together with the sequential evolution of data over time leads the sustainable production planning problem to a nonlinear mixed-integer stochastic programming model. We use scenario generation based approach and feasible neighborhood search for solving the model.

Prions and blood products.  

PubMed

The transmission of Creutzfeldt-Jakob disease (CJD) by human pituitary-derived growth hormone has led to concerns that blood products might also provide a route for the iatrogenic transmission of CJD. A number of actions have been implemented by regulatory authorities to address such concerns, and numerous studies have been undertaken to determine whether or not there is a risk of CJD being transmitted in this manner. To date, no excess risk has been identified, leading to a growing consensus that there is little or no risk of long established forms of CJD being transmitted to recipients of blood products. This opinion does not extend to new variant CJD (vCJD) which is found predominantly in the UK and is believed to have resulted from the transmission of bovine spongiform encephalopathy (BSE) to humans. Unlike that of CJD, the prevalence of vCJD is not known. In addition, the detection of abnormal prion protein in the tonsils of vCJD-infected individuals has led to speculation that blood infectivity may be greater than in patients with CJD. A number of precautionary measures have been taken to address the possibility that vCJD may be transmissible by blood products; however, further scientific advances are needed to enable this risk to be defined. A suitable screening test is required to identify any infected blood donors, particularly where cellular blood components are being derived from populations believed to be at risk from BSE infection. Recent experimental data suggest that process operations used in the manufacture of plasma products may be capable of removing prion agents to a significant extent. However, further work is required to confirm these observations and to determine whether or not all potential vCJD infectivity would be removed by these means. PMID:11087171

Speech perception and production  

PubMed Central

Until recently, research in speech perception and speech production has largely focused on the search for psychological and phonetic evidence of discrete, abstract, context-free symbolic units corresponding to phonological segments or phonemes. Despite this common conceptual goal and intimately related objects of study, however, research in these two domains of speech communication has progressed more or less independently for more than 60 years. In this article, we present an overview of the foundational works and current trends in the two fields, specifically discussing the progress made in both lines of inquiry as well as the basic fundamental issues that neither has been able to resolve satisfactorily so far. We then discuss theoretical models and recent experimental evidence that point to the deep, pervasive connections between speech perception and production. We conclude that although research focusing on each domain individually has been vital in increasing our basic understanding of spoken language processing, the human capacity for speech communication is so complex that gaining a full understanding will not be possible until speech perception and production are conceptually reunited in a joint approach to problems shared by both modes.

Advanced Production Planning Models  

SciTech Connect

>This report describes the innovative modeling approach developed as a result of a 3-year Laboratory Directed Research and Development project. The overall goal of this project was to provide an effective suite of solvers for advanced production planning at facilities in the nuclear weapons complex (NWC). We focused our development activities on problems related to operations at the DOE's Pantex Plant. These types of scheduling problems appear in many contexts other than Pantex--both within the NWC (e.g., Neutron Generators) and in other commercial manufacturing settings. We successfully developed an innovative and effective solution strategy for these types of problems. We have tested this approach on actual data from Pantex, and from Org. 14000 (Neutron Generator production). This report focuses on the mathematical representation of the modeling approach and presents three representative studies using Pantex data. Results associated with the Neutron Generator facility will be published in a subsequent SAND report. The approach to task-based scheduling described here represents a significant addition to the literature for large-scale, realistic scheduling problems in a variety of production settings.

Benzene Production on Mars  

NASA Astrophysics Data System (ADS)

The Methane to Aromatics on Mars (METAMARS) system is an in situ resource utilization (ISRU) technique that converts methane produced from the carbon dioxide in the martian atmosphere to low hydrogen content liquid aromatic fuels for an Earth Return Vehicle, thus greatly increasing the leverage of the hydrogen imported from the Earth. More importantly, the METAMARS system reduces the amount of hydrogen imported from Earth by a factor of four, leading to dramatic reductions in mission cost. This project involves design and construction of two fully functional oxygen/aromatic hydrocarbon production facilities (brassboard and protoflight) sized to produce 1 kg of bipropellant per day. Because aromatic fuels contain only about one hydrogen atom per carbon atom, the METAMARS system gives extremely high leverages on the order of 53 in the production of fuel and oxidizer for a Mars Sample Return (MSR) mission and human Mars missions. In addition, there are extensive potential commercial applications for the technology in converting trillions of cubic feet of stranded natural gas into easily transportable liquid aromatic products.

Biological production of hydrogen  

SciTech Connect

All Phase I objectives were satisfactorily achieved. Stoichiometric yields of hydrogen were obtained from CO with R. rubrum. Fast growth was observed on synthesis gas only; however, growth was maximized with a small amount of yeast extract at 30[degrees]C and pH 7. Intrinsic kinetic parameters were determined and showed that fast hydrogen production rates are possible. The Phase II research program concentrated on defining the optimal culture and bioreactor for hydrogen production. To insure that the best possible system was developed, cultures were screened for enzyme activity and hydrogen production. Promising cultures were optimized for hydrogen yield and CO conversion. Bioreactors that achieved high mass transfer rates, as well as high cell concentrations, were studied. Advanced bioreactor concepts, such as solid-state fermentation, non-aqueous fermentation, and high pressure fermentation were applied to these reactors to enhance mass transport. Process design and economic evaluations of the various alternatives were used to guide the research program. A new bacterial culture has been isolated from natural sources which consumes CO rapidly and gives high hydrogen yields. The new isolate, ERIH2, is able to utilize a variety of sugars as growth substrates and, unlike R. rubrum, does not require light for growth. The yield of H[sub 2] by ERIH2 reach 100 percent. Typical H[sub 2] yields by R. rubrum were 75--85 percent.

This review aims at providing an overview on the microbial production of vanillin, a new alternative method for the production of this important flavor of the food industry, which has the potential to become economically competitive in the next future. After a brief description of the applications of vanillin in different industrial sectors and of its physicochemical properties, we described the traditional ways of providing vanillin, specifically extraction and chemical synthesis (mainly oxidation) and compared them with the new biotechnological options, i.e., biotransformations of caffeic acid, veratraldehyde and mainly ferulic acid. In the second part of the review, emphasis has been addressed to the factors most influencing the bioproduction of vanillin, specifically the age of inoculum, pH, temperature, type of co-substrate, as well as the inhibitory effects exerted either by excess substrate or product. The final part of the work summarized the downstream processes and the related unit operations involved in the recovery of vanillin from the bioconversion medium.

Ordered product delivery date management system for management product or part production slot exchange  

US Patent & Trademark Office Database

When content of a production slot database indicates that there is no free production slot which can be allocated to an ordered vehicle designated in received order information, a production management section exchanges a production slot assigned to a potential vehicle so that the ordered vehicle can be delivered by the desired date. When no potential vehicle slot is available, a production slot for an ordered vehicle can be exchanged with that for another ordered vehicle for which a production slot has been secured, and the production slot date of the other vehicle is postponed to another day before the desired delivery date. When a production slot is secured before the desired delivery date but the production slot for a part required for producing the ordered vehicle cannot be secured, management of exchange is performed for the part according to a parts production slot database to enable delivery of as many vehicles by the delivery dates desired by customers as possible.

Fuel from microalgae lipid products  

SciTech Connect

The large-scale production of microalgae is a promising method of producing a renewable feedstock for a wide variety of fuel products currently refined from crude petroleum. These microalgae-derived products include lipid extraction products (triglycerides, fatty acids, and hydrocarbons) and catalytic conversion products (paraffins and olefins). Microalgal biomass productivity and lipid composition of current experimental systems are estimated at 66.0 metric tons per hectare year and 30% lipid content. Similar yields in a large-scale facility indicate that production costs are approximately six times higher than the average domestic price for crude, well-head petroleum. Based on achievable targets for productivity and production costs, the potential for microalgae as a fuel feedstock is presented in context with selected process refining routes and is compared with conventional and alternative feedstocks (e.g., oilseeds) with which microalgae must compete. 24 references, 9 figures, 4 tables.

Microbiological Spoilage of Cereal Products  

NASA Astrophysics Data System (ADS)

A wide range of cereal products, including bakery items, refrigerated dough, fresh pasta products, dried cereal products, snack foods, and bakery mixes, are manufactured for food consumption. These products are subject to physical, chemical, and microbiological spoilage that affects the taste, aroma, leavening, appearance, and overall quality of the end consumer product. Microorganisms are ubiquitous in nature and have the potential for causing food spoilage and foodborne disease. However, compared to other categories of food products, bakery products rarely cause food poisoning. The heat that is applied during baking or frying usually eliminates pathogenic and spoilage microorganisms, and low moisture contributes to product stability. Nevertheless, microbiological spoilage of these products occurs, resulting in substantial economic losses.

Tobacco and Nicotine Product Testing  

PubMed Central

Introduction: Tobacco product testing is a critical component of the Family Smoking Prevention and Tobacco Control Act (FSPTCA), which grants the Food and Drug Administration the authority to regulate tobacco products. The availability of methods and measures that can provide accurate data on the relative health risks across types of tobacco products, brands, and subbrands of tobacco products on the validity of any health claims associated with a product, and on how consumers perceive information on products toxicity or risks is crucial for making decisions on the product's potential impact on public health. These tools are also necessary for making assessments of the impact of new indications for medicinal products (other than cessation) but more importantly of tobacco products that may in the future be marketed as cessation tools. Objective: To identify research opportunities to develop empirically based and comprehensive methods and measures for testing tobacco and other nicotine-containing products so that the best science is available when decisions are made about products or policies. Methods: Literature was reviewed to address sections of the FSPTCA relevant to tobacco product evaluation; research questions were generated and then reviewed by a committee of research experts. Results: A research agenda was developed for tobacco product evaluation in the general areas of toxicity and health risks, abuse liability, consumer perception, and population effects. Conclusion: A cohesive, systematic, and comprehensive assessment of tobacco products is important and will require building consensus and addressing some crucial research questions.

Using appropri ated mathematical and statistical models, one can predict the kinetic profile of drugs and their metabolites and, consequently, develop preventive procedures regarding drug transmission (i.e., determination of appropriate withdrawal periods). Nevertheless, in the present chapter the mathematical and statistical concepts for data interpretation are strictly given to allow understanding of some basic pharma-cokinetic principles and to illustrate the determination of withdrawal periods

The CLAS detector is a large acceptance spectrometer located at the electron accelerator at Thomas Jefferson National Accelerator Facility. Production of K+ and K* mesons along with associated hyperons were measured using the CLAS detector at electron beam energies of 2.4-4.4 GeV. In addition, polarization transfer from the electron helicity to the Lambda hyperon was measured. These data are compared with theoretical models, where available, based on fits to older, less precise K+ data. The new data for CLAS indicate that improvements in the models are necessary in order to interpret the results.

In planning and managing production systems, manufacturers have two main strategies for responding to uncertainty: they build inventory to hedge against periods in which the production capacity is not sufficient to satisfy demand, or they temporarily increase the production capacity by “purchasing” extra capacity. We consider the problem of minimizing the long-run average cost of holding inventory and\\/or purchasing extra

Product life trade-offs: what if products fail early?  

PubMed

Increasing product life allows the embodied emissions in products to be spread across a longer period but can mean that opportunities to improve use-phase efficiency are foregone. In this paper, a model that evaluates this trade-off is presented and used to estimate the optimal product life for a range of metal-intensive products. Two strategies that have potential to save emissions are explored: (1) adding extra embodied emissions to make products more sturdy, increasing product life, and (2) increasing frequency of use, causing early product failure to take advantage of improvements in use-phase efficiency. These strategies are evaluated for two specific case studies (long-life washing machines and more frequent use of vehicles through car clubs) and for a range of embodied and use-phase intensive products under different use-phase improvement rate assumptions. Particular emphasis is placed on the fact that products often fail neither at their design life nor at their optimal life. Policy recommendations are then made regarding the targeting of these strategies according to product characteristics and the timing of typical product failure relative to optimal product life.

Accelerators for energy production  

NASA Astrophysics Data System (ADS)

A tremendous progress of accelerators for these several decades, has been motivated mainly by the research on subnuclear physics. The culmination in high energy accelerators might be SSC, 20 TeV collider in USA, probably the ultimate accelerator being built with the conventional principle. The technology cultivated and integrated for the accelerator development, can now stably offer the high power beam which could be used for the energy problems. The Inertial Confinement Fusion (ICF) with high current, 10 kA and short pulse, 20 ns heavy ion beam (HIB) of mass number approximately 200, would be the most promising application of accelerators for energy production. In this scenario, the fuel containing D-T mixture, will be compressed to the high temperature, approximately 10 keV and to the high density state, approximately 1000 times the solid density with the pressure of ablative plasma or thermal X ray produced by bombarding of high power HIB. The efficiency, beam power/electric power for accelerator, and the repetition rate of HIB accelerators could be most suitable for the energy production. In the present paper, the outline of HIB ICF (HIF) is presented emphasizing the key issues of high current heavy ion accelerator system.

The production of understanding.  

PubMed

While there is little doubt that sociological theory and research has had an important impact on the way people think about health and health care, mental health and medical sociologists are often confronted with challenges concerning the utility of the work that they do. Among the doubters are deans, funding agencies and family members. We are challenged by the ascendency of biological interpretations of human behaviors, by the incompatibility between the contextual view we prefer and the very strong individualistic orientation of our culture, and by the fact that we do not have an applied arm that trains the professionals who treat health and mental-health conditions. How do we respond to this challenge? The title of this paper gives a short answer: "The Production of Understanding." I propose that a powerful but under-recognized value of our work is the generation of explanations about health and mental health matters that help people understand the other side of an "us"/"them" divide. We produce understanding in a context in which misunderstanding is regularly constructed by powerful people who offer victim-blaming explanations for the circumstances experienced by people with less power. The production of understanding serves as an important counterbalance to this tendency. Our work shapes the way people think about problems related to health and mental health, limits the power of inaccurate victim-blaming accounts and provides understanding about why health and mental health are mal-distributed among people from different social circumstances.

IN DRIFT CORROSION PRODUCTS  

SciTech Connect

As directed by a written development plan (CRWMS M&O 1999a), a conceptual model for steel and corrosion products in the engineered barrier system (EBS) is to be developed. The purpose of this conceptual model is to assist Performance Assessment Operations (PAO) and its Engineered Barrier Performance Department in modeling the geochemical environment within a repository drift, thus allowing PAO to provide a more detailed and complete in-drift geochemical model abstraction and to answer the key technical issues (KTI) raised in the NRC Issue Resolution Status Report (IRSR) for the Evolution of the Near-Field Environment (NFE) Revision 2 (NRC 1999). This document provides the conceptual framework for the in-drift corrosion products sub-model to be used in subsequent PAO analyses including the EBS physical and chemical model abstraction effort. This model has been developed to serve as a basis for the in-drift geochemical analyses performed by PAO. However, the concepts discussed within this report may also apply to some near and far-field geochemical processes and may have conceptual application within the unsaturated zone (UZ) and saturated zone (SZ) transport modeling efforts.

Additional Pu-238 production  

SciTech Connect

Possible DOD demands for up to 1 MW thermal of heat sources could be partially met by increasing SRP Pu-238 production. The Pu-238 would be an alternate or supplement to Sr-90 in these heat sources. There is a growing surplus of Np-237 target material which could be used to produce high-assay Pu-238 (83.5%). In addition SRP produces low assay Pu-238 (approx. 27%) that could be extracted instead of being sent to the waste tanks. About 216 kg or 121 kw thermal of additional high-assay Pu-238 could be produced at SRP through FY1997; it would produce power at an incremental cost of approx. $1160/watt. About 77 kg or 44 kw thermal of low assay Pu-238 could also be recovered through FY1997; it would generate power at approx. $1850/watt. These quantities would supply only a fraction (approx. 1/6 of the 1 MW demand projection. Also the costs are considerably higher than the costs for Sr-90 fission product heat sources. Sr-90 from SRP and Hanford could supply the total 1 MW thermal requirement (150 MCi at $1 to $3 per Ci) at costs in the range of $150 to $450 per watt.

Neonatal energy substrate production.  

PubMed

Glucose is the most important foetal energy substrate. At birth the transplacental transfer of substrates is terminated. Before the start of breastfeeding the newborn infant must produce its own glucose particularly for the need of the central nervous system. Neonatal hypoglycaemia commonly occurs in risk groups such as immature and low birth weight infants, infants of mothers with diabetes and infants born large for gestational age. Our data show that extremely immature infants can also produce their own glucose during the first day of postnatal life. Although their stores of depot fat are limited, they also have a capacity for lipolysis. Infants of diabetic mothers have unimpaired lipolysis in spite of hyperinsulinaemia. This may represent a mechanism to compensate for the reduced rate of glucose production in these infants. The number of infants born large for gestational age is increasing in several countries partly consequent to increases in maternal weight. We have shown that foetal weight depends on maternal glucose production, which in turn is related to parameters associated with maternal fat mass. Like infants born small for gestational age, those born large for gestational age are at risk for metabolic disease later in life. Owing to a high fat mass these infants have a high rate of lipolysis, which can be one reason underlying the reduced insulin sensitivity seen already during the first day of life. PMID:20090117

Of the 242 major gas fields in the Permian basin, 67 are on the Central Basin Platform, 59 are in the Delaware basin, 44 are in the Midland basin, 28 are in the Val Verde basin, 24 are on the Eastern Shelf, 12 are in the Horshoe Atoll and eight are on the Northwest Shelf. Eleven fields have produced over one trillion cubic feet of gas, 61 have produced between 100 billion and one trillion cubic feet of gas and 170 have produced less than 100 billion cubic feet. Highlights of the study show 11% of the gas comes from reservoirs with temperatures over 300 degrees F. and 11% comes from depths between 19,000 and 20,000 feet. Twenty percent of the gas comes from reservoirs with pressures between 1000 and 2000 psi, 22% comes from reservoirs with 20-24% water saturation and 24% comes from reservoirs between 125 and 150 feet thick. Fifty-three reservoirs in the Ellenburger formation have produced 30% of the gas, 33% comes from 88 reservoirs in the Delaware basin and 33% comes from reservoirs with porosities of less than five percent. Forty percent is solution gas and 46% comes from combination traps. Over 50% of the production comes from reservoirs with five millidarcys or less permeability, and 60% of the gas comes from reservoirs in which dolomite is the dominant lithology. Over 50% of the gas production comes from fields discovered before 1957 although 50% of the producing fields were not discovered until 1958.

Cosmological element production.  

PubMed

Two recent observations appear to have provided critical information about the past history of the universe. The thermal character of the microwave background radiation suggests that the universe has expanded from a state of high temperature and density, and places constraints on such a big-bang cosmology. The observations of very weak helium lines in the spectra of certain stars in the halo of our galaxy are possibly due to a low primeval abundance of this element. However, the simplest model of a big-bang cosmology leads to much higher helium abundances, such as are observed in the solar system and in many stars. The production of helium can be reduced either by altering the early expansion rate or by introducing degenerate electron neutrinos. Observations of interstellar and intergalactic deuterium and He(4), and possibly even He(3) and Li(7), are needed to test the various models. PMID:17839602

The initial design is based on a 94.35% recovery of dichlorosilane in the distillate and a 99.9% recovery of trichlorosilane in the bottoms. The specified separation is achieved at a reflux ratio of 15 with 20 trays (equilibrium stages). Additional specifications and results are reported including equipment size, temperatures and pressure. Specific raw material requirements necessary to produce the silicon in the process are presented. The primary raw materials include metallurgical grade silicon, silicon tetrachloride, hydrogen, copper (catalyst) and lime (waste treatment). Hydrogen chloride is produced as by product in the silicon deposition. Cost analysis of the process was initiated during this reporting period.

Radioisotope production linac  

SciTech Connect

A 70-MeV proton beam would open a new family of medical radioisotopes (including the important /sup 123/I) to wide application. A 70-MeV, 500-..mu..A linac is described, based on recent innovations in accelerator technology. It would be 27.3 m long, cost approx. $6 million, and the cost of power deposited in the radioisotope-production target is comparable to existing cyclotrons. By operating the rf-power system to its full capability, the same accelerator is capable of producing a 1140-..mu..A beam, and the cost per beam watt on the target is less than half that of comparable cyclotrons. The technology to build such a linac is in a mature stage of developmnt, ready for use by industry.

Formate production through biocatalysis.  

PubMed

The generation of formate from CO 2 provides a method for sequestration of this greenhouse gas as well as the production of a valuable commodity chemical and stabilized form of hydrogen fuel. Formate dehydrogenases are enzymes with the potential to catalyze this reaction; however they generally favor the reverse process, i.e., formate oxidation. By contrast, the formate dehydrogenase of the acetogen Clostridium carboxidivorans has been found to preferentially catalyze the reduction of CO 2. This is in accord with its natural role to introduce CO 2 as a carbon source in the Wood-Ljungdahl pathway. The direction of catalysis derives from the enzyme's low affinity for formate. This enzyme is therefore an excellent candidate for biotechnological applications aimed at producing formic acid and derivative chemicals from CO 2. PMID:23841981

Lens design for production  

NASA Astrophysics Data System (ADS)

During the lens design process the experienced optical designer will examine the design as it evolves to identify any possibilities of lens simplification that may lead to a more cost effective and reliable final product. In this paper the author describes a recent lens design assignment and presents details of how he applied his background and experience to incorporate a number of these design simplification elements. A series of experiments are scheduled for the year 2005 on board the International Space Station under the directon of the Canadian Space Agency. Among these are a number of experiments where the effects of the space environment on several populations of fruit flies will be observed. These observations will be made, not only on board the Space Station, but also remotely via a video link to numerous scientists here on earth. In order to accomplish this remote link, a high quality video camera will need to be an integral part of each insect habitat module.

Observation of WZ production.  

PubMed

We report the first observation of the associated production of a W boson and a Z boson. This result is based on 1.1 fb;-1 of integrated luminosity from pp collisions at sqrt[s]=1.96 TeV collected with the CDF II detector at the Fermilab Tevatron. We observe 16 WZ candidates passing our event selection with an expected background of 2.7+/-0.4 events. A fit to the missing transverse energy distribution indicates an excess of events compared to the background expectation corresponding to a significance equivalent to 6 standard deviations. The measured cross section is sigma(pp-->WZ)=5.0(-1.6)(+1.8) pb, consistent with the standard model expectation. PMID:17501412

Production of zinc pellets  

DOEpatents

Uniform zinc pellets are formed for use in batteries having a stationary or moving slurry zinc particle electrode. The process involves the cathodic deposition of zinc in a finely divided morphology from battery reaction product onto a non-adhering electrode substrate. The mossy zinc is removed from the electrode substrate by the action of gravity, entrainment in a flowing electrolyte, or by mechanical action. The finely divided zinc particles are collected and pressed into pellets by a mechanical device such as an extruder, a roller and chopper, or a punch and die. The pure zinc pellets are returned to the zinc battery in a pumped slurry and have uniform size, density and reactivity. Applications include zinc-air fuel batteries, zinc-ferricyanide storage batteries, and zinc-nickel-oxide secondary batteries. 6 figs.

LCLS undulator production.  

SciTech Connect

Design and construction of the undulators for the linac coherent light source (LCLS) at the Stanford Linear Accelerator Center (SLAC) is the responsibility of Argonne National Laboratory (ANL). A full-scale prototype undulator was constructed in-house and extensively tested at Argonne's advanced photon source (APS). The device was tunable to well within the LCLS requirements and was stable for five years. Experience constructing the prototype undulator led us to conclude that with appropriate engineering design and detailed assembly procedures, precision undulators can be constructed by highly-qualified industrial vendors without undulator-construction experience. Argonne's detailed technological knowledge and experience were transferred to the successful bidders who produced outstanding undulators. Our production concept for the 3.4-m-long, fixed-gap, planar-hybrid undulators with a 30-mm period is discussed. Manufacturing, quality assurance, and acceptance testing details are also presented.

Biomimetic Production of Hydrogen  

NASA Astrophysics Data System (ADS)

The basic reaction for hydrogen generation is formation of molecular hydrogen from two electrons and two protons. Although there are many possible sources for the protons and electrons, and a variety of mechanisms for providing the requisite energy for hydrogen synthesis, the most abundant and readily available source of protons and electrons is water, and the most attractive source of energy for powering the process is sunlight. Not surprisingly, living systems have evolved to take advantage of these sources for materials and energy. Thus, biology provides paradigms for carrying out the reactions necessary for hydrogen production. Photosynthesis in green plants uses sunlight as the source of energy for the oxidation of water to give molecular oxygen, protons, and reduction potential. Some photosynthetic organisms are capable of using this reduction potential, in the form of the reduced redox protein ferredoxin, to reduce protons and produce molecular hydrogen via the action of an hydrogenase enzyme. A variety of other organisms metabolize the reduced carbon compounds that are ultimately the major products of photosynthesis to produce molecular hydrogen. These facts suggest that it might be possible to use light energy to make molecular hydrogen via biomimetic constructs that employ principles similar to those used by natural organisms, or perhaps with hybrid "bionic" systems that combine biomimetic materials with natural enzymes. It is now possible to construct artificial photosynthetic systems that mimic some of the major steps in the natural process.(1) Artificial antennas based on porphyrins, carotenoids and other chromophores absorb light at various wavelengths in the solar spectrum and transfer the harvested excitation energy to artificial photosynthetic reaction centers.(2) In these centers, photoinduced electron transfer uses the energy from light to move an electron from a donor to an acceptor moiety, generating a high-energy charge-separated state. Subsequent electron transfer reactions further separate the electron and hole spatially, reducing the electronic coupling, slowing charge recombination, and lengthening the useful lifetime of the charge separation.(3) Still following the example of natural bacterial photosynthesis, these artificial reaction centers may be inserted into the lipid bilayer membranes of liposomes. There, they are used to power transmembrane proton pumps based on a redox loop that employs a lipid-soluble quinone molecule to shuttle hydrogen ions across the membrane, acidifying the interior of the liposome.(4) Finally, ATP synthase isolated from spinach can be inserted into the liposomal bilayer. Protons flow out of the liposome through the enzyme, driven by the gradient produced by the proton pump. The energy released is used to convert adenosine diphosphate into adenosine triphosphate, which is a major biological energy currency.(5) The chromophores used in these artificial photosynthetic reaction centers may also be attached to wide band gap nanoparticulate semiconductor electrodes, where their excited states inject electrons into the semiconductor, generating the radical cation of the chromophore. Such electrodes have been incorporated into a photoelectrochemical biofuel cell.(6) In the cell, NADH reduces the radical cation, regenerating the chromophore and ultimately producing NAD+. The NAD+ is recycled by converting it back to NADH via dehydrogenase enzymes that oxidize carbohydrates and similar reduced carbon compounds, including glucose, ethanol and methanol. Addition of a suitable cathode produces a cell that generates electric current through the combined action of light and enzymatic oxidation. The two examples of artificial photosynthesis discussed above are potential sources of the reducing power necessary for hydrogen production. A biomimetic approach to this goal is to couple an artificial photosynthetic system to an enzymatic system for hydrogen production isolated from a suitable organism. Some possible approaches to achieving this will be discussed. References (

Gut triglyceride production  

PubMed Central

Our knowledge of how the body absorbs triacylglycerols (TAG) from the diet and how this process is regulated has increased at a rapid rate in recent years. Dietary TAG are hydrolyzed in the intestinal lumen to free fatty acids (FFA) and monoacylglycerols (MAG), which are taken up by enterocytes from their apical side, transported to the endoplasmic reticulum (ER) and resynthesized into TAG. TAG are assembled into chylomicrons (CM) in the ER, transported to the Golgi via pre-chylomicron transport vesicles and secreted towards the basolateral side. In this review, we mainly focus on the roles of key proteins involved in uptake and intracellular transport of fatty acids, their conversion to TAG and packaging into CM. We will also discuss intracellular transport and secretion of CM. Moreover, we will bring to light few factors that regulate gut triglyceride production. Furthermore, we briefly summarize pathways involved in cholesterol absorption.

Global production through 2005  

SciTech Connect

Two companion studies released recently should provide great food for thought among geo-political strategists and various national governments. If predictions contained in these Petroconsultants studies of oil and gas production trends for the next 10 years are realized, there will be great repercussions for net exporters and importers, alike. After analyzing and predicting trends within each of the world`s significant producing nations for the 1996--2005 period, the crude oil and condensate report concludes tat global production will jump nearly 24%. By contrast, worldwide gas output will leap 40%. The cast of characters among producers and exporters that will benefit from these increases varies considerably for each fuel. On the oil side, Russia and the OPEC members, particularly the Persian Gulf nations, will be back in the driver`s seat in terms of affecting export and pricing patterns. On the gas side, the leading producers will be an interesting mix of mostly non-OPEC countries. The reemergence of Persian Gulf oil producers, coupled with an anticipated long-term decline among top non-OPEC producing nations should present a sobering picture to government planners within large net importers, such as the US. They are likely to find themselves in much the same supply trap as was experienced in the 1970s, only this time the dependence on foreign oil supplies will be much worse. Gas supplies will not be similarly constrained, and some substitution for oil is probable. Here, two articles, ``World oil industry is set for transition`` and ``Worldwide gas surges forward in next decade,`` present a summary of the findings detailed in Petroconsultants` recent studies.

Microbial Production of Isoprene  

SciTech Connect

Isoprene is a volatile hydrocarbon of unknown function, produced by certain bacteria, plants and animals, sometimes in huge amounts—the Earth’s forests are estimated to emit >500 x 106 tons of isoprene per year. With funding from this program we explored the biochemistry and regulation of isoprene formation in the model bacterial system, Bacillus subtilis, with the goals of explaining the biological rationale for isoprene biogenesis and constructing an isoprene-overproducing microbial system. Although the role for isoprene formation in B. subtilis is still uncertain, our current model for regulation of this hydrocarbon’s synthesis is that isoprene production in B. subtilis is controlled by a combination of i) rapid regulation of isoprene synthase activity and ii) supply of the substrate for isoprene synthase, dimethyallyl diphosphate (DMAPP). This model parallels our current thinking about the control of isoprene formation in plant chloroplasts. In this reporting period we have been working to test part ii) of this model; this work has produced new results using genetic and analytical approaches. For examples, we have developed an analytical method to resolve DMAPP and its isomer, isopentenyl diphosphate, from each other in bacteria and plants. We have also shown that the IPP isomerase (type 2) of B. subtilis is not the source of “isoprene synthase” activity, and discovered that B. subtilis releases C5 isoprenoid alcohols to the medium, suggesting that isoprene plus other C5 isoprenoids may be common by-products of metabolism. In addition, we have continued to work on our discovery that wild type B. subtilis strains form prolific biofilms, are normal components of plant root microflora, and are testing the idea that B. subtilis growing in biofilms uses isoprene to induce plant root exudation.

2-Phenylethanol (2-PE) is an important flavour and fragrance compound with a rose-like odour. Most of the world's annual production of several thousand tons is synthesised by chemical means but, due to increasing demand for natural flavours, alternative production methods are being sought. Harnessing the Ehrlich pathway of yeasts by bioconversion of L-phenylalanine to 2-PE could be an option, but in situ product removal is necessary due to product inhibition. This review describes the microbial production of 2-PE, and also summarizes the chemical syntheses and the market situation. PMID:12073125

Preservatives in registered chemical products.  

PubMed

Preservatives are common causes of contact allergy and contact dermatitis. Exposure to cosmetics, personal care products, consumer products and occupationally used products often involve contact with the same range of preservatives. The aim of this study is to provide an overview on the occurrence of preservatives in registered chemical products. The studied preservatives included substances from standard patch test series and other preservatives relevant for registered chemical products. Data obtained from the Danish Product Register Database (PROBAS) in January 2005 were compared to similar data from January 2002. Paints/lacquers, cleaning agents and printing inks were the most frequently registered product categories, and the studied preservatives were registered in most of the product categories included in the study. For most product categories the total number of registered products was stable during the study period. Butylated hydroxytoluene, benzoic acid, isothiazolinones, Bronopol and formaldehyde showed an increase from 2002 to 2005. Most of these changes occurred in the product category paints/lacquers, for which a doubling mainly due to a change in registration practice was observed. The frequent registration of isothiazolinones (MCI/MI and benzisothiazolinone) in paints/lacquers may be a possible explanation for the relative high and stable frequency of positive patch test reactions to MCI/MI.

Energy implications of product leasing.  

PubMed

A growing number of advocates have argued that leasing is a "greener" form of business transactions than selling. Leasing internalizes the costs of process wastes and product disposal, placing the burden on the OEMs, who gain from reducing these costs. Product leasing results in closed material loops, promotes remanufacturing or recycling, and sometimes leads to shorter life cycles. This paper provides two case studies to quantitatively test these claims for two distinct product categories. Life cycle optimization and scenario analysis are applied, respectively, to the household appliance and computer industries to determine the effect that life spans have on energy usage and to what extent leasing the product versus selling it may influence the usage life span. The results show that products with high use impacts and improving technology can benefit from reduced life cycles (achieved through product leases), whereas products with high manufacturing impacts and no improving technology do not.

Product quality of parenteral vancomycin products in the United States.  

PubMed

In response to concerns raised about the quality of parenteral vancomycin products, the U.S. Food and Drug Administration (FDA) is investigating the product quality of all FDA-approved parenteral vancomycin products available in the United States. Product quality was evaluated independently at two FDA Office of Testing and Research (FDA-OTR) sites. In the next phase of the investigation, being done in collaboration with the National Institute of Allergy and Infectious Diseases, the in vivo activity of these products will be evaluated in an appropriate animal model. This paper summarizes results of the FDA investigation completed thus far. One site used a validated ultrahigh-pressure liquid chromatography method (OTR-UPLC), and the second site used the high-performance liquid chromatography (HPLC) method for related substances provided in the British Pharmacopeia (BP) monograph for vancomycin intravenous infusion. Similar results were obtained by the two FDA-OTR laboratories using two different analytical methods. The products tested had 90 to 95% vancomycin B (active component of vancomycin) by the BP-HPLC method and 89 to 94% vancomycin by OTR-UPLC methods. Total impurities were 5 to 10% by BP-HPLC and 6 to 11% by OTR-UPLC methods. No single impurity was >2.0%, and the CDP-1 level was ? 2.0% across all products. Some variability in impurity profiles of the various products was observed. No adverse product quality issues were identified with the six U.S. vancomycin parenteral products. The quality parameters of all parenteral vancomycin products tested surpassed the United States Pharmacopeia acceptance criteria. Additional testing will characterize in vivo performance characteristics of these products. PMID:22314525

PRODUCTION OF CARBON PRODUCTS USING A COAL EXTRACTION PROCESS  

SciTech Connect

This Department of Energy National Energy Technology Laboratory sponsored project developed carbon products, using mildly hydrogenated solvents to extract the organic portion of coal to create synthetic pitches, cokes, carbon foam and carbon fibers. The focus of this effort was on development of lower cost solvents, milder hydrogenation conditions and improved yield in order to enable practical production of these products. This technology is needed because of the long-term decline in production of domestic feedstocks such as petroleum pitch and coal tar pitch. Currently, carbon products represents a market of roughly 5 million tons domestically, and 19 million tons worldwide. Carbon products are mainly derived from feedstocks such as petroleum pitch and coal tar pitch. The domestic supply of petroleum pitch is declining because of the rising price of liquid fuels, which has caused US refineries to maximize liquid fuel production. As a consequence, the long term trend has a decline in production of petroleum pitch over the past 20 years. The production of coal tar pitch, as in the case of petroleum pitch, has likewise declined significantly over the past two decades. Coal tar pitch is a byproduct of metallurgical grade coke (metcoke) production. In this industry, modern metcoke facilities are recycling coal tar as fuel in order to enhance energy efficiency and minimize environmental emissions. Metcoke production itself is dependent upon the production requirements for domestic steel. Hence, several metcoke ovens have been decommissioned over the past two decades and have not been replaced. As a consequence sources of coal tar are being taken off line and are not being replaced. The long-term trend is a reduction in coal tar pitch production. Thus import of feedstocks, mainly from Eastern Europe and China, is on the rise despite the relatively large transportation cost. To reverse this trend, a new process for producing carbon products is needed. The process must be economically competitive with current processes, and yet be environmentally friendly as well. The solvent extraction process developed uses mild hydrogenation of low cost oils to create powerful solvents that can dissolve the organic portion of coal. The insoluble portion, consisting mainly of mineral matter and fixed carbon, is removed via centrifugation or filtration, leaving a liquid solution of coal chemicals and solvent. This solution can be further refined via distillation to meet specifications for products such as synthetic pitches, cokes, carbon foam and fibers. The most economical process recycles 85% of the solvent, which itself is obtained as a low-cost byproduct from industrial processes such as coal tar or petroleum refining. Alternatively, processes have been developed that can recycle 100% of the solvent, avoiding any need for products derived from petroleum or coal tar.

JWST mirror production status  

NASA Astrophysics Data System (ADS)

The James Webb Space Telescope (JWST) is an on axis three mirror anastigmat telescope with a primary mirror, a secondary mirror, and a tertiary mirror. The JWST mirrors are constructed from lightweight beryllium substrates and the primary mirror consists of 18 hexagonal mirror segments each approximately 1.5 meters point to point. Ball Aerospace and Technologies Corporation leads the mirror manufacturing team and the team utilizes facilities at six locations across the United States. The fabrication process for each individual mirror assembly takes approximately six years due to limitations dealing with the number of segments and manufacturing & test facilities. The primary mirror Engineering Development Unit (EDU) recently completed the manufacturing process with the final cryogenic performance test of the mirror segment assembly. The 18 flight primary mirrors segments, the secondary mirror, and the tertiary mirror are all advanced in the mirror production process with many segments through the final polishing process, coating process, final assembly, vibration testing, and final acceptance testing. Presented here is a status of the progress through the manufacturing process for all of the flight mirrors.

Regulation of biomedical products.  

PubMed

Two recent decisions, one from Australia and one from Canada, should cause us to examine the ethical issues surrounding the regulation of biomedical products. The protection of vulnerable consumers from variable quality and poorly prepared drugs with uncertain parameters of safety and efficacy is a priority for any community and should not have to be weighed against possible costs based on restrictions of trade. However, the possibility of an environment in which the multinational biomedical industry edges out any other players in the treatment of various illnesses has its own dangers. Not least is the apparent collusion between regulators and industry that ramps up the costs and intensity of licensing and risk management so that only an industry-type budget can sustain the costs of compliance. This has the untoward effect of delivering contemporary health care into the hands of those who make immense fortunes out of it. An approach to regulation that tempers bureaucratic mechanisms with a dose of common sense and realistic evidence-based risk assessment could go a long way in avoiding the Scylla and Charybdis awaiting the clinical world in these troubled waters.

Detecting livestock production zones.  

PubMed

Communities are sets of nodes that are related in an important way, most likely sharing common properties and/or playing similar roles within a network. Unraveling a network structure, and hence the trade preferences and pathways, could be useful to a researcher or a decision maker. We implemented a community detection algorithm to find livestock communities, which is consistent with the definition of a livestock production zone, assuming that a community is a group of farm premises in which an animal is more likely to stay during its lifetime than expected by chance. We applied this algorithm to the network of animal movements within the state of Mato Grosso for 2007. This database holds information concerning 87,899 premises and 521,431 movements throughout the year, totaling 15,844,779 animals moved. The community detection algorithm achieved a network partition that shows a clear geographical and commercial pattern, two crucial features for preventive veterinary medicine applications; this algorithm provides also a meaningful interpretation to trade networks where links emerge based on trader node choices.

Early humour production.  

PubMed

The current studies explored early humour as a complex socio-cognitive phenomenon by examining 2- and 3-year-olds' humour production with their parents. We examined whether children produced novel humour, whether they cued their humour, and the types of humour produced. Forty-seven parents were interviewed, and videotaped joking with their children. Other parents (N= 113) completed a survey. Parents reported children copy jokes during the first year of life, and produce novel jokes from 2 years. In play sessions, 3-year-olds produced mostly novel humorous acts; 2-year-olds produced novel and copied humorous acts equally frequently. Parents reported children smile, laugh, and look for a reaction when joking. In play sessions, 2- and 3-year-olds produced these behaviours more when producing humorous versus non-humorous acts. In both parent reports and play sessions, they produced novel object-based (e.g., underwear on head) and conceptual humour (e.g., 'pig says moo') and used wrong labels humorously (e.g., calling a cat a dog). Thus, parent report and child behaviour both confirm that young children produce novel humorous acts, and share their humour by smiling, laughing, and looking for a reaction. PMID:23039334

STUDIES ON ANTIBODY PRODUCTION  

PubMed Central

After injection of ovalbumin as a water-in-oil emulsion a pronounced adjuvant effect is demonstrable following the incorporation of tubercle bacillary wax into the oily phase of the mixture. With single doses of antigen (10 mg. ovalbumin) there is a 4- to 5-fold increase in the amount of antibody at the median of 3 week serum levels in animals receiving a small dose of wax (40 µg.). With a 5 mg. dose of wax there is an 8-fold increase in serum antibody levels at the median. A striking feature of the action of wax is the stimulation of a macrophage proliferation locally at the site of injection, and the production of morphological abnormalities in these cells. As judged by staining techniques for antibody content, these locally assembled cells are not active in the formation of antibody. Wax injected in mineral oil results in a remarkable systematized stimulation of the reticulo-endothelial system. The greatly increased serum antibody levels demonstrated after the use of tubercle bacillary wax in antigen mixtures is attributed to a widespread proliferation of plasma cell elements in the lymphatic glands, spleen and liver.

CPV Energy Production Analysis  

NASA Astrophysics Data System (ADS)

This work describes a simple method that predicts the CPV energy production (EP) by using Global Horizontal Irradiation (GHI) data from weather stations and the PVGIS database. To establish and examine this prediction model, we analyze data from four CPV installations of different radiation conditions in Spain. The EP prediction involves two steps. First, since Direct Normal Irradiation (DNI) is not widely measured, it is estimated based on real-time GHI and PVGIS data over an average year. Second, the EP is extrapolated as a linear function of the estimated DNI. This is based on the fact that the real EP data from these CPV installations shows very good linearity with respect to the estimated DNI. Moreover, this characteristic does not change when moving from a low radiation location to a high radiation one. Thus, our proposed model uses GHI data from nearby weather stations and the PVGIS database and predicts the performance of CPV installations at any location. Our prediction closely matches the real EP. For the installations we have studied, the difference between the predicted and the real annual EP is less than 2% and the average difference between the predicted and the real monthly EP is in the range of 5-16%.

Waste product profile: Glass containers  

SciTech Connect

In 1992, Waste Age initiated the Waste Product Profile series -- brief, factual listings of the solid waste management characteristics of materials in the solid waste stream. This popular series of profiles high-lighted a product, explained how it fit into integrated waste management systems, and provided current data on recycling and markets for the product. Glass containers are made from sand, limestone, soda ash, cullet (crushed bottles), and various additives, including those used to produce green, brown, and blue glass. Other glass products include flat glass, such as windows, and fiberglass products, such as insulation and glassware. These products are manufactured using different processes and different additives than container glass. This profile covers only glass containers.

Floating units cut production costs  

SciTech Connect

Nine operating semisubmersible and tanker production platform facilities are currently supplying the technology and experiential data necessary for development of floating production systems for depth applications of 1000 to 10,000 ft. Sedco-Hamilton Production Services has developed a 4-well deepwater system consisting of a floating tanker or semi moored on short lines to 4 permanent catenary moored springbuoys. The platform is linked to a seabed tree array through the hull centerline via a flexible, retrievable production riser bundle. Costs associated with floating production platforms normally are lower than those of fixed platforms. A major factor is the decision to convert an existing drilling rig into the production mode or alternatively opt for a new build.

Production of Pseudoscalar Mesons  

NASA Astrophysics Data System (ADS)

Experiments that study the hadronic and electromagnetic production of the pseudoscalar mesons - pions, etas and kaons, contribute to our knowledge of the properties of baryon and hyperon resonances. Fixed-target programs at hadronic facilities, such as BNL-AGS, have been phased out. However, the availability of modern experimental facilities with pseudo-monochromatic or tagged medium-energy photon beams at GRAAL, SPring-8, Bonn, Mainz, and Jefferson Lab, together with LEGS, Max-Lab, and HIGS at lower energies, are beginning to produce high-quality results. These new data have smaller statistical uncertainties and better understood systematic uncertainties, than those obtained at the older bremsstrahlung facilities, for measurements of differential and integrated cross sections, as well as polarization and asymmetry. Experimental results are compared with the predictions of QCD-based approaches, such as the lattice-gauge calculations of baryon properties, and chiral perturbation theory applied to threshold photoproduction, and are essential to the performance of partial-wave analyses (PWA). These PWA studies are less model dependent than in the past, and are used in coupled-channels calculations that incorporate unitarity dynamically, and combine results from hadronic reaction channels with electromagnetic processes. This approach is necessary to extract resonance properties and may lead to the discovery of the "missing resonances" predicted by a number of different QCD-inspired calculations. We discuss recent experimental and phenomenological results for single and double pseudoscalar meson hadronic and photoproduction channels with emphasis on the JLab Hall B and the BNL/AGS Crystal Ball programs.

Imitation during phoneme production.  

PubMed

Does listening to and observing the speaking interlocutor influence phoneme production? In two experiments female participants were required to recognize and, then, to repeat the string-of-phonemes /aba/ presented by actors visually, acoustically and audiovisually. In experiment 1 a male actor presented the string-of-phonemes and the participants' lip kinematics and voice spectra were compared with those of a reading control condition. In experiment 2 female and male actors presented the string-of-phonemes and the lip kinematics and the voice spectra of the participants' responses to the male actors were compared with those to the female actors (control condition). In both experiments 1 and 2, the lip kinematics in the visual presentations and the voice spectra in the acoustical presentations changed in the comparison with the control conditions approaching the male actors' values, which were different from those of the female participants and actors. The variation in lip kinematics induced changes also in voice formants but only in the visual presentation. The data suggest that both features of the lip kinematics and of the voice spectra tend to be automatically imitated when repeating a string-of-phonemes presented by a visible and/or audible speaking interlocutor. The use of imitation, in place of the usual lip kinematics and vocal features, suggests an automatic and unconscious tendency of the perceiver to interact closely with the interlocutor. This is in accordance with the idea that resonant circuits are activated by the activity of the mirror system, which relates observation to execution of arm and mouth gestures. PMID:16698051

Consumer oriented product noise testing  

NASA Astrophysics Data System (ADS)

This paper explores the need for product noise measurements and how best to meet that need in the near future. Currently there is only a small market place for quieter consumer products. This is not because of lack of interest. No one really wants to announce to everyone in their house that they just flushed the toilet, few really want the entire neighborhood to know they are mowing their yard, etc. The small market place is primarily due to a lack of regulations on product noise, a lack of information easily available to consumers about which products are quieter, and market consolidation resulting in fewer manufacturers, most of whom are unwilling to emphasize their quieter products at the risk of eroding sales of their noisier ones (that currently have greater market share). In the absence of the EPA fulfilling its statutory requirement to regulate and label product noise under the Noise Control Act of 1972, and with the unwillingness of most industries to voluntarily publish accurate product noise data, there is a significant role for ``Consumer Oriented Product Noise Testing.'' This paper explores the Noise Pollution Clearinghouse's ongoing and planned product noise testing, evaluating its advantages, disadvantages, and limitations.

The power of product integrity.  

PubMed

In the dictionary, integrity means wholeness, completeness, soundness. In products, integrity is the source of sustainable competitive advantage. Products with integrity perform superbly, provide good value, and satisfy customers' expectations in every respect, including such intangibles as their look and feel. Consider this example from the auto industry. In 1987, Mazda put a racy four-wheel steering system in a five-door family hatchback. Honda introduced a comparable system in the Prelude, a sporty, two-door coupe. Most of Honda's customers installed the new technology; Mazda's system sold poorly. Potential customers felt the fit--or misfit--between the car and the new component, and they responded accordingly. Companies that consistently develop products with integrity are coherent, integrated organizations. This internal integrity is visible at the level of strategy and structure, in management and organization, and in the skills, attitudes, and behavior of individual designers, engineers, and operators. Moreover, these companies are integrated externally: customers become part of the development organization. Integrity starts with a product concept that describes the new product from the potential customer's perspective--"pocket rocket" for a sporty, subcompact car, for example. Whether the final product has integrity will depend on two things: how well the concept satisfies potential customers' wants and needs and how completely the concept has been embodied in the product's details. In the most successful development organizations, "heavyweight" product managers are responsible for leading both tasks, as well as for guiding the creation of a strong product concept.

Intermediate inputs and economic productivity.  

PubMed

Many models of economic growth exclude materials, energy and other intermediate inputs from the production function. Growing environmental pressures and resource prices suggest that this may be increasingly inappropriate. This paper explores the relationship between intermediate input intensity, productivity and national accounts using a panel dataset of manufacturing subsectors in the USA over 47 years. The first contribution is to identify sectoral production functions that incorporate intermediate inputs, while allowing for heterogeneity in both technology and productivity. The second contribution is that the paper finds a negative correlation between intermediate input intensity and total factor productivity (TFP)--sectors that are less intensive in their use of intermediate inputs have higher productivity. This finding is replicated at the firm level. We propose tentative hypotheses to explain this association, but testing and further disaggregation of intermediate inputs is left for further work. Further work could also explore more directly the relationship between material inputs and economic growth--given the high proportion of materials in intermediate inputs, the results in this paper are suggestive of further work on material efficiency. Depending upon the nature of the mechanism linking a reduction in intermediate input intensity to an increase in TFP, the implications could be significant. A third contribution is to suggest that an empirical bias in productivity, as measured in national accounts, may arise due to the exclusion of intermediate inputs. Current conventions of measuring productivity in national accounts may overstate the productivity of resource-intensive sectors relative to other sectors. PMID:23359736

I construct a canonical basis in the tensor product of a simple integrable highest weight module with a simple integrable lowest weight module of a quantized enveloping algebra. This basis is simultaneously compatible with many submodules of the tensor product. As an application, I obtain a construction of a canonical basis of (a modified form of) the quantized enveloping algebra.

Noncommutative Translations and *-PRODUCT Formalism  

NASA Astrophysics Data System (ADS)

We consider the noncommutative space-times with Lie-algebraic noncommutativity (e.g. ?-deformed Minkowski space). In the framework with classical fields we extend the *-product in order to represent the noncommutative translations in terms of commutative ones. We show the translational invariance of noncommutative bilinear action with local product of noncommutative fields. The quadratic noncommutativity is also briefly discussed.

HMI Magnetic Field Data Products  

NASA Astrophysics Data System (ADS)

The Helioseismic and Magnetic Imager (HMI) instrument on the Solar Dynamics Observatory (SDO) spacecraft will begin observing the solar photospheric magnetic field continuously after commissioning in early 2009. This paper describes the HMI magnetic processing pipeline and the expected data products that will be available. The full disk line-of-sight magnetic field will be available every minute with 1" resolution. Comparable vector measurements collected over a three-minute time interval will ordinarily be averaged for at least 10 minutes before inversion. Useful Quick Look products for forecasting purposes will be available a few minutes after observation. Final products will be computed within 36 hours and made available through the SDO Joint Science Operations Center (JSOC). Three kinds of magnetic data products have been defined - standard, on-demand, and on-request. Standard products, such as frequently updated synoptic charts, are made all the time on a fixed cadence. On-demand products, such as high cadence full-disk disambiguated vector magnetograms, will be generated whenever a user asks for them. On-request products, such as high-resolution time series of MHD model solutions, will be generated as resources allow. This paper describes the observations, magnetograms, synoptic and synchronic products, and field model calculations that will be produced by the HMI magnetic pipeline.

Succinate production in Escherichia coli.  

PubMed

Succinate has been recognized as an important platform chemical that can be produced from biomass. While a number of organisms are capable of succinate production naturally, this review focuses on the engineering of Escherichia coli for the production of four-carbon dicarboxylic acid. Important features of a succinate production system are to achieve an optimal balance of reducing equivalents generated by consumption of the feedstock, while maximizing the amount of carbon channeled into the product. Aerobic and anaerobic production strains have been developed and applied to production from glucose and other abundant carbon sources. Metabolic engineering methods and strain evolution have been used and supplemented by the recent application of systems biology and in silico modeling tools to construct optimal production strains. The metabolic capacity of the production strain, the requirement for efficient recovery of succinate, and the reliability of the performance under scaleup are important in the overall process. The costs of the overall biorefinery-compatible process will determine the economic commercialization of succinate and its impact in larger chemical markets. PMID:21932253
