Full Text Available Skorup is Montenegrin traditional dairy product. Its main characteristics are extremely high content of milk fat and centuries-old technology. Due to the specific technology, high nutritional value and its historical heritage, Skorup deserves to be labelled as product with protected designation of origin (PDO or protected geographical indication (PGI. The purpose of this study was to collect the most important data about Skorup technology and quality and to launch the process of protection. The chemical quality of raw milk was analysed using IR spectrophotometry, the number of somatic cells and total bacteria count by flow cytometry, and Skorup composition by FTIR spectrophotometry. The presence of Escherichia coli, coagulase positive staphylococci and aerobic mesophilic bacteria in Skorup was detected by standard broth base methods. All Skorup samples contained more than 80 % of fat in dry matter, more than 70 % dry matter, approximately 60 % milk fat and 6 % proteins. The sensory characteristics of all samples were excellent, and according to sensory classification, they belong to the highest classes (I and IA. However, five out of twenty samples did not meet requirements for hygienic quality, which implies the urgent need for improvement of hygiene conditions during its production.

Jong-il Kim

2006-06-01

Full Text Available This study tries to quantify the technology level of products based on the concept of product ladder. While many studies on country technology competitiveness use the aggregate indices such as total factor productivity and revealed comparative advantage, this study estimates the ranking of about 2000 products in product ladder by using SITC 5 digit level export data. Based on the product ladder, this study measures the country and industry ranking and explores the characteristics of the ranking. It provides the international comparison of inter-industry and intra-industry ranking differences in product ladder. The statistical relationships between the ranking in product ladder and the determinants of technology level such as R&D and physical capital investment and wage, confirms that the measured ranking in product ladder could be regarded as an indirect indicator of technology level. The product ladder is applied to the estimation of production function to see the effect of the product differentiation on labor productivity.

Ethanol production by extractive fermentation - Process development and technology transfer

International Nuclear Information System (INIS)

Daugulis, A.J.; Axford, D.B.; Mau, T.K.

1991-01-01

Extractive Fermentation is an ethanol processing strategy in which the operations of fermentation and product recovery are integrated and undertaken simultaneously in a single step. In this process an inert and biocompatible organic solvent is introduced directly into the fermentation vessel to selectively extract the ethanol product. The ethanol is readily recovered from the solvent at high concentration by means of flash vaporization, and the solvent is recycled in a closed loop back to the fermentor. This process is characterized by a high productivity (since ethanol does not build up to inhibitory levels), continuous operation, significantly reduced water consumption, and lower product recovery costs. The technical advantages of this processing strategy have been extensively demonstrated by means of a continuous, fully integrated and computer-controlled Process Demonstration Unit in the authors' laboratory. Numerous features of this technology have been protected by US patent. A thorough economic comparison of Extractive Fermentation relative to modern ethanol technology (continuous with cell recycle) has been completed for both new plants and retrofitting of existing facilities for a capacity of 100 million liters of ethanol per year. Substantial cost savings are possible with Extractive Fermentation ranging, depending on the process configuration, from 5 cents to 16 cents per liter. Activities are under way to transfer this proprietary technology to the private sector

Nowadays, consumer demand is driving better and more nutritious dairy products. Changing from traditional to new lactose-free products poses technological challenges for the food industry in order to maintain or improve their food characteristics and consumer preferences. This study investigates the production of lactose-free frozen yogurt by enzymati- cally hydrolysis of lactose, and its influence on the final product characteristics. In the case of lactose-free products, commercial Ha-lactase® was used for hydrolysis, and the reaction occurred simultaneously with fermentation. The effect of lactose hydrolysis on the physicochemical properties, texture, viscosity, overrun and sensory attributes in the final product was investigated. After yogurt maturation, the acidity of the lactose-free product was significantly higher than in the control, suggesting that breaking down lactose enhances the fermentation process. Lactose-free frozen yogurt had significantly lower hardness and stickiness and higher viscosity than control frozen yogurt. Moreover, lactose hydrolysis promoted a smooth and creamy consistency, whereas in the case of conventional prod- ucts a coarse structure, due to the presence of large ice crystals, was identified. Hydrolysis of lactose also improved the sweetness and brightness of frozen yogurt. The improved textural properties of lactose-free product results from the fact that monosaccharides produced during lactose hydrolysis depress the freezing point of the mix, which enables product with softer structure and bigger resistance to ice recrystallization to be obtained. The study showed that lactose-free frozen yogurt may be used successfully for production of novel lactose-free frozen desserts. Lactose hydrolysis improves the texture and viscosity of the product,     as well as enhancing its sensory quality.

Depleted uranium (DU) has been used during the War in Yugoslavia in the year 1999 by NATO forces, as well as in Bosnia and Gulf War. In Yugoslavia it has been used in two modalities: as ammunition (mostly caliber 30 mm) and as a part of cruise missiles (counterweight penetrator). Total amount of DU in Yugoslavia was about 10 tons. DU is a by product of nuclear technology and represents low-level nuclear waste. Therefore it should be stored. But, because of military application it is in the environment where it could react chemo toxically or radio toxically and so endanger people and animals. This paper contains all relevant technology parameters of DU created as a by product, DU physical and chemical properties, DU ammunition effects, environmental DU transport, and estimation of consequences on people and environment

The objective of this study was to evaluate the effects of supplying the by-product of peach-palm (Bactris gasipaes) on performance and characteristics of carcass and non-carcass components of feedlot lambs. Twenty Santa Ines lambs of 150 days average age and 22.4 ± 3.4 kg body weight were confined in individual pens. A completely randomized design was utilized with four experimental diets composed of: fresh peach-palm by-product enriched with urea, fresh peach-palm by-product + concentrate, silage of peach-palm by-product + concentrate, and silage of peach-palm by-product enriched with 15 % corn meal + concentrate. Intake was evaluated daily, and at the end of 42 days of experiments, lambs were slaughtered and the characteristics of carcass and non-carcass parts were evaluated. Performance and carcass characteristics showed differences between the animals' intake of total mixed rations (TMR) and only the diet with roughage. For the lambs that intaked TMR, the form of utilization of roughage (fresh or as silage) affected animal performance but did not change the carcass characteristics. Dry matter intake and feed conversion were influenced by the form of utilization of the silage (with and without additive). Providing fresh by-product plus concentrate improves lamb performance but does not interfere in the carcass characteristics, compared with the use of by-product in the form of silage.

Preference Evaluation System for Construction Products Using QFD-TOPSIS Logic by Considering Trade-Off Technical Characteristics

Full Text Available This paper investigates the feasibility of quality function deployment, technique for the order of preference by similarity to ideal solution (QFD-TOPSIS in presenting user preferences for multiple alternatives, such as construction technologies, products, systems, and design solutions, with trade-off technical characteristics (TC. The original QFD as house of quality (HOQ defines the requirements and features as subjective matrix relations, which cause interpretations to vary across users and limit its industrial applications. QFD-TOPSIS is a new model that combines the benefits of QFD with those of TOPSIS, maintains the subjectivity and objectivity evaluation of the technical characteristics (TC, and rates the preferences by considering users’ individual propensity for requirements. In addition, QFD-TOPSIS rates the preferences through the reciprocal compensation effects of trade-off TC and filters unsuitable alternatives with predefined restrictive conditions. Trade-off refers to conflicts and/or contradictions between attributes, often arising in multicriteria decision-making. Users or project stakeholder groups define the priorities of trade-off TC that directly influence product preferences and decision-making. In the present study, we have developed a Web system based on the QFD-TOPSIS logic and tested its operation to verify its industrial applicability and viability for automatic quality evaluation.

Value analysis for advanced technology products

Soulliere, Mark

2011-03-01

Technology by itself can be wondrous, but buyers of technology factor in the price they have to pay along with performance in their decisions. As a result, the ``best'' technology may not always win in the marketplace when ``good enough'' can be had at a lower price. Technology vendors often set pricing by ``cost plus margin,'' or by competitors' offerings. What if the product is new (or has yet to be invented)? Value pricing is a methodology to price products based on the value generated (e.g. money saved) by using one product vs. the next best technical alternative. Value analysis can often clarify what product attributes generate the most value. It can also assist in identifying market forces outside of the control of the technology vendor that also influence pricing. These principles are illustrated with examples.

Astaxanthin is a carotenoid known for its strong antioxidant and health-promoting characteristics, but it is also highly degradable and thus unsuited for several applications. We developed a sustainable method for the extraction and the production of stable astaxanthin microencapsulates. Nearly 2% astaxanthin was extracted by high-pressure homogenization of dried Haematococcus pluvialis cells in soybean oil. Astaxanthin-enriched oil was encapsulated in alginate and low-methoxyl pectin by Ca 2+ -mediated vibrating-nozzle extrusion technology. The 3% pectin microbeads resulted the best compromise between sphericity and oil retention upon drying. We monitored the stability of these astaxanthin beads under four different conditions of light, temperature and oxygen exposition. After 52weeks, the microbeads showed a total-astaxanthin retention of 94.1±4.1% (+4°C/-light/+O 2 ), 83.1±3.2% (RT/-light/-O 2 ), 38.3±2.2% (RT/-light/+O2), and 57.0±0.4% (RT/+light/+O 2 ), with different degradation kinetics. Refrigeration, therefore, resulted the optimal storage condition to preserve astaxanthin stability. Copyright © 2016 Elsevier Ltd. All rights reserved.

Rather high moisture content of many vegetables, e.g., fruit, partially fills the needs of the human organism in water, lowers the energy value of the diet, enhances the motility of the gastrointestinal tract. In this regard, the improvement of technology universal product from regional vegetables available has got importance, prolonged pronounced social effect and contributes to health improvement. Among vegetables the zucchini include diet properties, but the use of them is accompanied by certain difficulties associated with seasonal logistics and the limited range of products from them. In this work, there were studied the varietal characteristics of the zucchini, zoned in the North-West region, in terms of their technological properties, morphological characteristics and biochemical composition of fruit during ripening. Were investigated the optimal ways of canning zucchini by drying with freeze-drying and infrared heating that allows you to provide catering universal semi-finished product during the whole year, not only in areas of cultivation, but also in areas outside of growing vegetables. There was discovered the effect of anomalous dehydration of fruit vegetables in the result of the study , which helped to explain the increased, in comparison with other types of vegetables, losses during heat treatment and to justify their methods and technological parameters of drying. It was found that one of the reasons for the reduction of mechanical strength parenchymal tissue of fruit vegetables, is the destruction of cell walls by increasing the pressure inside the air inclusions, in contrast to some other types of fruit

Natova Margarita

2018-01-01

Full Text Available During conventional polymer injection molding, flow- and weld lines can arise at the molded parts caused by disturbed polymer melt flow when it crosses different parts of the equipment. Such processed plastic goods have discrete zones of inhomogeneities of very small dimensions. In order to stabilize the melt flow and to equalize dimensions of such defective products, an approach for pulse injection molding is applied during production of polymer packagings. Testing methods used for evaluation of macromechanical performance of processed polymer products are not readily applicable to estimate the changes in visual surface obtained during pulse injecting. To overcome this testing inconvenience the performance of processed packagings is evaluated by nanoindentation. Using this method, a quantitative assessment of the polymer properties is obtained from different parts of technological products.

Horse meat and its products can be considered as a food with a high nutritional value. However, due to cases of economically motivated food adulteration by the intentional addition of horse meat beef products in recent years, horse meat has become a controversial issue. Consumer confidence in meat products and the meat industry has diminished, although consumers consider the differences between the food content and the label as the major issue rather than the safety and nutritional characteristics of horse meat. The elaboration of meat products from horse meat (e.g. "cecina", dry-cured loin, salami, bressaola and pâté) is also an interesting alternative to other traditional meat products such as dry-cured pork hams, pork sausages and liver pâtés. In this review, the technological aspects, safety and storage stability of meat products elaborated from horse meat will be addressed by highlighting the nutritional and sensory aspects of these meat products. We aim to improve the existing knowledge about horse meat in the view of recent scandals. Copyright © 2017 Elsevier Ltd. All rights reserved.

The present study aimed to use liquid whey as an ingredient in the formulation of ice cream, hard candies, ham and breads, as well as to evaluate the influence of it in technological characteristics of the products and to quantify the volume of whey used. In order to evaluate the use of liquid whey, the products were developed with partial or total replacement of milk or water by whey, being the substitution accompanied by the determination of centesimal composition, as well as evaluating the visual characteristics of each product. The results show that the preparation of the products under study with substitution of raw milk or water is viable, proving that using liquid whey is a technological possibility of using a by-product considered to be an environmental pollutant. It was concluded that the use of liquid whey in the food industry reduces the environmental impact, since there is a reduction in the volume of whey discharged into the environment.

Influence of High Hydrostatic Pressure Technology on Wine Chemical and Sensorial Characteristics: Potentialities and Drawbacks.

Science.gov (United States)

Nunes, Cláudia; Santos, Mickael C; Saraiva, Jorge A; Rocha, Sílvia M; Coimbra, Manuel A

During last years, scientific research on high hydrostatic pressure (HHP) as a nonthermal processing technology for preservation or aging of wine has increased substantially. HHP between 200 and 500MPa is able to inactivate bacteria and yeasts in red and white wines, suggesting that it may be used for wine preservation. However, these treatments have been shown to promote changes on sensorial and physicochemical characteristics in both red and white wines, not immediately in the first month, but along storage. The changes are observed in wine color, aroma, and taste due mainly to reactions of phenolic compounds, sugars, and proteins. These reactions have been associated with those observed during wine aging, leading to aged-like wine characteristics perceived by sensorial analysis. This chapter will present the influence of HHP technology on wine chemical and sensorial characteristics, criticaly discussing its potentialities and drawbacks. The appropriate use of HHP, based on the scientific knowledge of the reactions occuring in wine promoted by HHP, will allow to exploit this technology for wine production achieving distinct characteristics to address particular market and consumer demands. © 2017 Elsevier Inc.

Packaging colour research by tobacco companies: the pack as a product characteristic.

Science.gov (United States)

Lempert, Lauren K; Glantz, Stanton

2017-05-01

Tobacco companies use colour on cigarette packaging and labelling to communicate brand imagery, diminish health concerns, and as a replacement for prohibited descriptive words ('light' and 'mild') to make misleading claims about reduced risks. We analysed previously secret tobacco industry documents to identify additional ways in which cigarette companies tested and manipulated pack colours to affect consumers' perceptions of the cigarettes' flavour and strength. Cigarette companies' approach to package design is based on 'sensation transference' in which consumers transfer sensations they derive from the packaging to the product itself. Companies manipulate consumers' perceptions of the taste and strength of cigarettes by changing the colour of the packaging. For example, even without changes to the tobacco blends, flavourings or additives, consumers perceive the taste of cigarettes in packages with red and darker colours to be fuller flavoured and stronger, and cigarettes in packs with more white and lighter colours are perceived to taste lighter and be less harmful. Companies use pack colours to manipulate consumers' perceptions of the taste, strength and health impacts of the cigarettes inside the packs, thereby altering their characteristics and effectively creating new products. In countries that do not require standardised packaging, regulators should consider colour equivalently to other changes in cigarette characteristics (eg, physical characteristics, ingredients, additives and flavourings) when making determinations about whether or not to permit new products on the market.

2016-03-01

A process was developed for the production of a high-protein food ingredient, soy-agushie, from the residual by-product of soymilk production. The product, with a moisture content of about 6%, was evaluated for its quality characteristics and performance in traditional dishes. The protein content was about 26% with similar amino acids content as that of the whole soybean. Lysine remained high in the dehydrated product (6.57 g/16 g N). While over 60% of the original B vitamins content in the beans was extracted with the milk, high proportions of the minerals were found to be retained in the residual by-product. The process adequately reduced the trypsin inhibitor levels in the beans from 25 to 1.5 mg/g. High sensory scores were obtained for recipes developed with soy-agushie in traditional dishes. The scope of utilization of the soy-agushie could be widened to include several traditional foods and bakery products for maximum nutritional benefits.

Kai Zhang

2016-06-01

Full Text Available Based on the analysis of the relationship between the process of product innovation design and knowledge, this article proposes a theoretical model of quality function knowledge deployment. In order to link up the product innovation design and the knowledge required by the designer, the iterative method of quality function knowledge deployment is refined, as well as the knowledge retrieval model and knowledge support model based on quality function knowledge deployment are established. In the whole life cycle of product design, in view of the different requirements for knowledge in conceptual design stage, components’ configuration stage, process planning stage, and production planning stage, the quality function knowledge deployment model could link up the required knowledge with the engineering characteristics, component characteristics, process characteristics, and production characteristics in the four stages using the mapping relationship between the function characteristics and the knowledge and help the designer to track the required knowledge for realizing product innovation design. In this article, an instance about rewinding machine is given to demonstrate the practicability and validity of product innovation design knowledge support technology based on quality function knowledge deployment.

Biofuels Fuels Technology Pathway Options for Advanced Drop-in Biofuels Production

Energy Technology Data Exchange (ETDEWEB)

Kevin L Kenney

2011-09-01

Advanced drop-in hydrocarbon biofuels require biofuel alternatives for refinery products other than gasoline. Candidate biofuels must have performance characteristics equivalent to conventional petroleum-based fuels. The technology pathways for biofuel alternatives also must be plausible, sustainable (e.g., positive energy balance, environmentally benign, etc.), and demonstrate a reasonable pathway to economic viability and end-user affordability. Viable biofuels technology pathways must address feedstock production and environmental issues through to the fuel or chemical end products. Potential end products include compatible replacement fuel products (e.g., gasoline, diesel, and JP8 and JP5 jet fuel) and other petroleum products or chemicals typically produced from a barrel of crude. Considering the complexity and technology diversity of a complete biofuels supply chain, no single entity or technology provider is capable of addressing in depth all aspects of any given pathway; however, all the necessary expert entities exist. As such, we propose the assembly of a team capable of conducting an in-depth technology pathway options analysis (including sustainability indicators and complete LCA) to identify and define the domestic biofuel pathways for a Green Fleet. This team is not only capable of conducting in-depth analyses on technology pathways, but collectively they are able to trouble shoot and/or engineer solutions that would give industrial technology providers the highest potential for success. Such a team would provide the greatest possible down-side protection for high-risk advanced drop-in biofuels procurement(s).

Strategies for fuel cell product development. Developing fuel cell products in the technology supply chain

International Nuclear Information System (INIS)

Hellman, H.L.

2004-01-01

Due to the high cost of research and development and the broad spectrum of knowledge and competences required to develop fuel cell products, many product-developing firms outsource fuel cell technology, either partly or completely. This article addresses the inter-firm process of fuel cell product development from an Industrial Design Engineering perspective. The fuel cell product development can currently be characterised by a high degree of economic and technical uncertainty. Regarding the technology uncertainty: product-developing firms are more often then not unfamiliar with fuel cell technology technology. Yet there is a high interface complexity between the technology supplied and the product in which it is to be incorporated. In this paper the information exchange in three current fuel cell product development projects is analysed to determine the information required by a product designer to develop a fuel cell product. Technology transfer literature suggests that transfer effectiveness is greatest when the type of technology (technology uncertainty) and the type of relationship between the technology supplier and the recipient are carefully matched. In this line of thinking this paper proposes that the information required by a designer, determined by the design strategy and product/system volume, should be met by an appropriate level of communication interactivity with a technology specialist.

Selecting appropriate technology for hydrogen production

International Nuclear Information System (INIS)

Tamhankar, S.S.

2004-01-01

'Full text:' Technologies for the production of synthesis gas (H2 + CO), a precursor to hydrogen, from a variety of fossil fuels are well known in industrial applications at relatively large scale. These include Steam Reforming (SR), Auto-Thermal Reforming (ATR) and Partial Oxidation (POX). A particular technology is selected based on the feed type and the desired products. Steam reforming is a mature technology, and is most prevalent for hydrogen production because of its high efficiency. However, at the smaller scale, the capital cost becomes a more significant factor, and a substantial reduction in this cost is necessary to meet the overall H2 gas cost targets, such as that stated by DOE ($1.50/kg). In developing small-scale H2 technologies, often, incremental improvements are incorporated. While useful, these are not adequate for the desired cost reduction. Also, for effective cost reduction, the whole system, including production, purification and associated equipment needs to be evaluated; cost reduction in just one of the units is not sufficient. This paper provides a critical assessment of the existing as well as novel technology options, specifically targeted at small scale H2 production. The technology options are evaluated to clearly point out which may or may not work and why. (author)

Advanced Decontamination Technologies: High Hydrostatic Pressure on Meat Products

Science.gov (United States)

Garriga, Margarita; Aymerich, Teresa

The increasing demand for “natural” foodstuffs, free from chemical additives, and preservatives has triggered novel approaches in food technology developments. In the last decade, practical use of high-pressure processing (HPP) made this emerging non-thermal technology very attractive from a commercial point of view. Despite the fact that the investment is still high, the resulting value-added products, with an extended and safe shelf-life, will fulfil the wishes of consumers who prefer preservative-free minimally processed foods, retaining sensorial characteristics of freshness. Moreover, unlike thermal treatment, pressure treatment is not time/mass dependant, thus reducing the time of processing.

Tc-99m is most frequently used in nuclear medical diagnostics because of its favourable nuclear properties and reasonable prices, and the demand of Tc-99m, is on the increase recently. Mo-99, the parent radionuclide of Tc-99m, is the only source of Tc-99m. This review described overall aspects of process technologies for Mo-99 production. Firstly, the chemical, physical and radioactive properties of Tc-99m, Mo-99 were examined to understand Mo-99 separation process. Also, the technology for Mo-99 production with both the neutron capture and nuclear fission method were examined. But the neutron capture method was scarcely used for large production of Mo-99 because of its low specific activity and high production cost. This review also described mainly process technologies in the nuclear fission method, fabrication and condition for irradiation of targets, transport and dissolution of targets irradiated, separation and purification of Mo-99, etc. Especially, for Mo-99 separation and purification process, the characteristics, merits and demerits of various processes, which have been developed in a few countries, were examined and analyzed. 30 figs., 16 tabs., 60 refs.

Mobile health technology is rapidly evolving with the potential to transform health care. Self-management of health facilitated by mobile technology can maximize long-term health trajectories of adults. Little is known about the characteristics of adults seeking Web-based support from health care providers facilitated by mobile technology. This study aimed to examine the following: (1) the characteristics of adults who seek human support from health care providers for health concerns using mobile technology rather than from family members and friends or others with similar health conditions and (2) the use of mobile health technology among adults with chronic health conditions. Findings of this study were interpreted in the context of the Efficiency Model of Support. We first described characteristics of adults seeking Web-based support from health care providers. Using chi-square tests for categorical variables and t test for the continuous variable of age, we compared adults seeking Web-based and conventional support by demographics. The primary aim was analyzed using multivariate logistic regression to examine whether chronic health conditions and demographic factors (eg, sex, income, employment status, race, ethnicity, education, and age) were associated with seeking Web-based support from health care providers. The sample included adults (N=1453), the majority of whom were female 57.60% (837/1453), white 75.02% (1090/1453), and non-Hispanic 89.13% (1295/1453). The age of the participants ranged from 18 to 92 years (mean 48.6, standard deviation [SD] 16.8). The majority 76.05% (1105/1453) of participants reported college or higher level of education. A disparity was found in access to health care providers via mobile technology based on socioeconomic status. Adults with annual income of US $30,000 to US $100,000 were 1.72 times more likely to use Web-based methods to contact a health care provider, and adults with an annual income above US $100,000 were 2.41 to

Beierlein, Jennifer M; McNamee, Laura M; Ledley, Fred D

2017-12-15

The long path from initial research on oligonucleotide therapies to approval of antisense products is not unfamiliar. This lag resembles those encountered with monoclonal antibodies, gene therapies, and many biological targets and is consistent with studies of innovation showing that technology maturation is a critical determinant of product success. We previously described an analytical model for the maturation of biomedical research, demonstrating that the efficiency of targeted and biological development is connected to metrics of technology growth. The present work applies this model to characterize the advance of oligonucleotide therapeutics. We show that recent oligonucleotide product approvals incorporate technologies and targets that are past the established point of technology growth, as do most of the oligonucleotide products currently in phase 3. Less mature oligonucleotide technologies, such as miRNAs and some novel gene targets, have not passed the established point and have not yielded products. This analysis shows that oligonucleotide product development has followed largely predictable patterns of innovation. While technology maturation alone does not ensure success, these data show that many oligonucleotide technologies are sufficiently mature to be considered part of the arsenal for therapeutic development. These results demonstrate the importance of technology assessment in strategic management of biomedical technologies. Copyright © 2017 The Authors. Published by Elsevier Inc. All rights reserved.

The objects formed by 3D printing, in particular from nonmetallic materials, have an essential disadvantage not eliminated at the present time - a significant anisotropy of the structure and, as a consequence, of physical and mechanical characteristics. The research of 3DP technology in combination with the influence of microwave electromagnetic field of various power on the formed three-dimensional product has been carried out. It was established that a microwave electromagnetic field with an average specific power of 2450 MHz causes an increase in the homogeneity of the of powder materials’ structure, expressed in a decrease of the pore size by 24% and a decrease in their dispersion by almost 30%. As a consequence of the increase in the homogeneity of the structure, the flexural strength of Zp130-powder plates impregnated with cyanoacrylate has increased to 1.77 times. Thus, the use of the microwave electromagnetic field as a final stage in the formation of products made from composite materials is promising and requires additional studies to justify the serial production technology.

Highlights: ► In this paper we review the technologies related to biodiesel production. ► 4 Primary approaches reviewed are direct use and blending of oils, micro-emulsions, pyrolysis and transesterification method. ► Both advantages and disadvantages of the different biodiesel production methods are also discussed. ► The most common technology of biodiesel production is transesterification of oils. ► Selection of a transesterification method depends on the amount of FFA and water content of the feedstock. - Abstract: Despite the high energy demand in the industrialized world and the pollution problems caused by widespread use of fossil fuels, the need for developing renewable energy sources with less environmental impacts are increasing. Biodiesel production is undergoing rapid and extensive technological reforms in industries and academia. The major obstacle in production and biodiesel commercialization path is production cost. Thus, in previous years numerous studies on the use of technologies and different methods to evaluate optimal conditions of biodiesel production technically and economically have been carried out. In this paper, a comparative review of the current technological methods so far used to produce biodiesel has been investigated. Four primary approaches to make biodiesel are direct use and blending of vegetable oils, micro-emulsions, thermal cracking (pyrolysis) and transesterification. Transesterification reaction, the most common method in the production of biodiesel, is emphasized in this review. The two types of transestrification process; catalytic and non-catalytic are discussed at length in the paper. Both advantages and disadvantages of the different biodiesel production methods are also discussed.

Long-term affected energy production of waste to energy technologies identified by use of energy system analysis.

Münster, M; Meibom, P

2010-12-01

Affected energy production is often decisive for the outcome of consequential life-cycle assessments when comparing the potential environmental impact of products or services. Affected energy production is however difficult to determine. In this article the future long-term affected energy production is identified by use of energy system analysis. The focus is on different uses of waste for energy production. The Waste-to-Energy technologies analysed include co-combustion of coal and waste, anaerobic digestion and thermal gasification. The analysis is based on optimization of both investments and production of electricity, district heating and bio-fuel in a future possible energy system in 2025 in the countries of the Northern European electricity market (Denmark, Norway, Sweden, Finland and Germany). Scenarios with different CO(2) quota costs are analysed. It is demonstrated that the waste incineration continues to treat the largest amount of waste. Investments in new waste incineration capacity may, however, be superseded by investments in new Waste-to-Energy technologies, particularly those utilising sorted fractions such as organic waste and refuse derived fuel. The changed use of waste proves to always affect a combination of technologies. What is affected varies among the different Waste-to-Energy technologies and is furthermore dependent on the CO(2) quota costs and on the geographical scope. The necessity for investments in flexibility measures varies with the different technologies such as storage of heat and waste as well as expansion of district heating networks. Finally, inflexible technologies such as nuclear power plants are shown to be affected. Copyright © 2010 Elsevier Ltd. All rights reserved.

Full Text Available The author explains the general principles of influence of the material and technical resources (MTR on performance and efficiency of the main technological operations in crop production. Various technologies from the point of view of MTR expenses were estimated. The general tendencies in development of crop production technologies were revealed. The distribution of costs of materials and equipment to perform a variety of agricultural activities was determined. Cost indicators should be a guide in the search of innovative technological processes and working elements of agricultural machins. The greatest values of expenses of work, fuel, metal, and also, money where found. The concepts allowing to provide costs production reduction were formulated. To achieve the maximum productivity with the minimum expenses, the perspective calculations shoul be based on «progressive» agrotechnologies. When determining progressive agrotechnology it is necessary on reasonable grounds to approach indicators of crop productivity in various agrozones and regions of the country. For an assessment of efficiency of MTR by crop production and ensuring decrease in resource intensity of agricultural products by search and use of essentially new technologies for energy saving when performing agricultural operations, an integrated percentage indicator of comparison of progressive technologies with the applied ones was developed. MTR at application of new progressive crop production technologies by integrated percentage index were estimated. This indicator can be used for definition of efficiency of MTR. Application of the offered technique will promote an effective assessment of MTR, decrease in resource intensity by search and developments of essentially new technologies of performance of operations in crop production.

Full Text Available The article analyses business processes and actions models, based on the utilization of new sciencedriven technologies used for the production of products and services that are implemented by large international industrial conglomerates within the framework of realizing the diversification strategies. As a research sample, we have chosen models of managing technological innovations, which formed the basis of the diversification strategy of Fujifilm Holdings Corporation in 2000–2015. The article notes that the company expedited the widening of new technological areas for development since the beginning of the 2000’s. High technology products manufactured using new technologies are no longer launched by the company every 7–10 years as in 20th century but instead, much more rapidly, every 3–4 years. There is noted a significant change in the company’s approach to reducing the life span of innovations. Today, Fujifilm prefers to enter new markets by purchasing innovations already used by medium sized fast growing high tech companies, and not form new research departments in their holding company. Attention is drawn to the fact that more often Fujifilm uses the strategy of unrelated diversification, by demonstrating whereby the readiness to widen the scope of its activities in any sphere with the good return on investments perspectives. The article emphasizes the significant importance of Russian industrial companies to be able to purchase innovative solutions and partner with providers of science-driven technologies and products, including small and medium-sized enterprises.

Production of FAME by palm oil transesterification via supercritical methanol technology

International Nuclear Information System (INIS)

Tan, Kok Tat; Lee, Keat Teong; Mohamed, Abdul Rahman

2009-01-01

The present study employed non-catalytic supercritical methanol technology to produce biodiesel from palm oil. The research was carried out in a batch-type tube reactor and heated beyond supercritical temperature and pressure of methanol, which are at 239 o C and 8.1 MPa respectively. The effects of temperature, reaction time and molar ratio of methanol to palm oil on the yield of fatty acid methyl esters (FAME) or biodiesel were investigated. The results obtained showed that non-catalytic supercritical methanol technology only required a mere 20 min reaction time to produce more than 70% yield of FAME. Compared to conventional catalytic methods, which required at least 1 h reaction time to obtain similar yield, supercritical methanol technology has been shown to be superior in terms of time and energy consumption. Apart from the shorter reaction time, it was found that separation and purification of the products were simpler since no catalyst is involved in the process. Hence, formation of side products such as soap in catalytic reactions does not occur in the supercritical methanol method.

This study investigates induced productivity effects of firms introducing new environmental technologies. The literature on within-firm organisational change and productivity suggests that firms can achieve higher productivity gains from adopting new technologies if they adapt their organisational structures. Such complementarity effects may be of particular importance for the adoption of greenhouse gas (GHG) abatement technologies. The adoption of these technologies is often induced by publi...

Evaluation of the efficiency of alternative enzyme production technologies

Energy Technology Data Exchange (ETDEWEB)

Albaek, M.O.

2012-03-15

fermentation technologies for enzyme production were identified in the open literature. Their mass transfer capabilities and their energy efficiencies were evaluated by use of the process model. For each technology the scale-up enzyme production was simulated at industrial scale based on equal mass transfer. The technical feasibility of each technology was assessed based on prior knowledge of successful implementation at industrial scale and mechanical complexity of the fermentation vessel. The airlift reactor was identified as a potential high energy efficiency technology for enzyme production with excellent chances for success. Two different pilot plant configurations of the airlift reactor technology were tested in nine fermentations. The headspace pressure was varied between 0.1 and 1.1 barg and the superficial gas velocity in the airlift riser section was varied between 0.02 and 0.06 m/s. The biological model developed in the stirred tank reactor was shown to apply to the airlift reactor with only small modifications: The mass transfer of oxygen in the airlift reactor was studied and a mass transfer correlation containing the superficial gas velocity and the apparent viscosity of the fermentation broth was shown to describe the experimental data well. The mass transfer rate was approximately 20% lower than the literature data for airlift reactors. Mixing in the pilot scale airlift reactor was also studied. As the mixing time was of the same order of magnitude as the characteristic time for oxygen transfer, mixing could also be limiting the process at that scale. The process model for the airlift reactor was also shown to describe the experimental data well for a range of process conditions. A cost function for oxygen transfer including the equipment cost and running cost for nutrients and electricity was developed for both the stirred tank reactor and the airlift reactor. The cost function was used to identify an optimum range of reactor configuration and process

The authors have been struggling to develop a new control technique for the production of shochu, a white distilled liquor made from sweet potato. Aiming to control the production of shochu specific flavor by regulating the expression of β-glucosidase, breeding of several strains of Aspergillus which express β-glucosidase at different levels was made by screening with radiation. Aspergillus M3 and U1, a high-production and a low-production strain of β-glucosidase, respectively were selected. The characteristics of the enzymes produced by these two and their parent strain were compared. There were no significant differences among the three enzymes in respects of optimum pH, pH stability etc. The practical availability of these strains was evaluated by a pilot-scale brewing test. U1 strain was found to have significantly less shochu-specific flavor and to be similar to the parent strain in respect of its production cost, whereas M3 strain was found to produce β-glucosidase at a high level and generate sufficiently strong flavor in the shochu, but there remains some problem in the cost because of the difficulty in adhesion of its conidia.

In order to develop shielding technology for high energy radiation production facility, references and data for high energy neutron shielding are searched and collected, and calculations to obtain the characteristics of neutron shield materials are performed. For the evaluation of characteristics of neutron shield material, it is chosen not only general shield materials such as concrete, polyethylene, etc., but also KAERI developed neutron shields of High Density PolyEthylene (HDPE) mixed with boron compound (B 2 O 3 , H 2 BO 3 , Borax). Neutron attenuation coefficients for these materials are obtained for later use in shielding design. The effect of source shape and source angular distribution on the shielding characteristics for several shield materials is examined. This effect can contribute to create shielding concept in case of no detail source information. It is also evaluated the effect of the arrangement of shield materials using current shield materials. With these results, conceptual shielding design for PET cyclotron is performed. The shielding composite using HDPE and concrete is selected to meet the target dose rate outside the composite, and the dose evaluation is performed by configuring the facility room conceptually. From the result, the proper shield configuration for this PET cyclotron is proposed

Sustainable thermal technologies and care homes: Productive alignment or risky investment?

The use of more sustainable thermal technologies is a policy imperative across the UK building stock. However, not all building uses provide the same opportunities for technology uptake as others. Care homes for older people have characteristics which in technical and economic terms suggest that they might be particularly appropriate for the implementation of more sustainable thermal technologies. They have comparatively high demands for space heating and hot water often sustained on a 24/7 basis. However there are many considerations, both generic and contextual, that will typically play into processes of technology uptake. Through qualitative research in six case study homes, focused on management and staff perspectives and experiences, we explore the degree to which there might be a productive alignment between care home operation and the use of sustainable thermal technologies. Two key themes emerge focused on business considerations and the importance of avoiding risk and damage to reputation; and the ways in which different thermal technologies are relevant to and can potentially impact on care practices. We conclude that despite potential benefits the sector could remain rather resistant to sustainability innovations. We suggest therefore areas in which productive action and further research could be undertaken. -- Highlights: •Care homes for older people might be particularly appropriate for the use of sustainable thermal technologies. •We examine if a productive alignment between care homes and the use of sustainable thermal technologies does exist in practice. •Two key themes are risks to business reputation; and relevance and potential benefits to care practices. •We conclude that the sector could remain rather reluctant to embrace sustainability innovation

This report describes the features of technology, the schedule and the organization for the research and development regarding the hydrogen production technology using FBR thermal energy. Now, the hydrogen production system is proposed as one of new business models for FBR deployment. This system is the production of hydrogen either thermal energy at approximately from 500degC to 550degC or electricity produced by a sodium cooled FBR. Hydrogen is expected to be one of the future clean secondary energies without carbon-dioxide emission. Meanwhile the global energy demand will increase, especially in Asian countries, and the energy supply by fossil fuels is not the best choice considering the green house effect and the stability of energy supply. The development of the hydrogen technology using FBR that satisfies 'sustainable energy development' and 'utilization of energies free from environmental pollution' will be one of the promising options. Based on the above mentioned recognition, we propose the direction of the development, the issues to be solved, the time schedule, the budget, and the organization for R and D of three hydrogen production technologies, the thermochemical hybrid process, the low temperature steam reforming process, and the high temperature steam electrolysis process in JNC.

Full Text Available Fermentation characteristics of grass and grass silage at different maturities were studied using in situ and in vitro gas production methods. In situ data determined difference between grass and silage. Degradable fraction decreased as grass matured while the undegradable fraction increased. Rate of degradation (kd was slower for silage than fresh grass. Gas production method (GP data showed that fermentation of degradable fraction was different between stage of maturity in both grass and silage. Other data did not show any difference with the exception for the rate of GP of soluble and undegradable fraction. The in situ degradation characteristics were estimated from GP characteristics. The degradable and undegradable fractions could be estimated by multiple relationships. Using the three-phases model for gas production kd and fermentable organic matter could be estimated from the same parameters. The only in situ parameter that could not be estimated with GP parameters was the soluble fraction. The GP method and the three phases model provided to be an alternative to the in situ method for animal feed evaluations.

Full Text Available Assistive technology (AT can help support the continued independence of people living with dementia, supported by informal carers. Opinions and preferences of informal carers towards a range of assistive and digital information and communication technologies (ICT to support food purchase and menu selection, including navigation and online shopping, and safe meal-making by individuals living with dementia were investigated. General attitudes and experiences with assistive technologies were first probed by means of a focus group with carers (n = 6, organised through the Alzheimer’s Society in Nottingham, England. A series of AT/ICT product brochures were then produced, describing packages of technologies to enable meal production. Task-specific questions were asked of carers (n = 10 at local Memory Cafés as to the perceived capabilities of each individual for shopping and meal-making. Carers were asked to make pair-wise choices in order to select a personalised brochure and to complete a questionnaire to elicit the practicality, desirability and affordability of specific products and to probe for preferences amongst key features. Opinions on ease-of-use, aesthetics, expected safety-in-use, independence of use and stigma related to the technology packages were also collected. Results showed that carers are able to make detailed choices and express preferences about assistive and digital technologies for the individuals in their care, and customise their enabler package. Most believed that having an enabler package would improve safety. Greater exposure of carers to newer digital products would be beneficial. The brochure method could be employed on consumer websites and by AT assessors.

Romanovich, A. A.; Glagolev, S. N.; Babaevsky, A. N.

2018-03-01

The article considers industrial technology and energy-saving equipment for cement and composite binder production with a reduction in energy intensity of the process up to 50% due to the synergetic effect during mechanic activation of the raw mix with the replacement of part of the clinker component with the mineral hydro-active additive. The technological process is based on the sequential introduction of components in dispersed phases into the feed mixture in the grinding path and at the stage of product separation with certain dispersed characteristics. The increase in the energy efficiency of the line is achieved by the joint operation of the press roller aggregate, which is the development of BSTU named after V.G. Shoukhov, and rotor-vortex mills of a very fine grinding of a new design. The experienced design of the aggregate with the device for deagglomeration of the pressed tape allows combining the processes of grinding and disaggregation of the pressed material, thereby reducing the operating costs and increasing the efficiency of using the grinding unit. Comparative tests of cement samples obtained in energy-saving aggregates (PRA + RVM) are given which allowed establishing that their beam strength for compression and bending is higher by 15-20% than the traditional method obtained in a ball mill. An analytical expression is also given that allows one to determine the power consumed for the deagglomeration of crushed and pressed material between the main rolls, taking into account the geometric dimensions of the rolls and the physico-mechanical characteristics of the material.

Highlights: • An interesting hysteresis phenomenon was analyzed using entropy production theory. • A function was used to calculate the entropy production in the wall region. • Generation mechanism of the hump and hysteresis characteristics was obtained. - Abstract: The hydraulic loss due to friction and unstable flow patterns in hydro-turbines causes a drop in their efficiency. The traditional method for analyzing the hydraulic loss is by evaluating the pressure drop, which has certain limitations and cannot determine the exact locations at which the high hydraulic loss occurs. In this study, entropy production theory was adopted to obtain a detailed distribution of the hydraulic loss in a pump-turbine in the pump mode. In the past, the wall effects of entropy production were not considered, which caused larger errors as compared with the method of pressure difference. First, a wall equation was proposed to calculate the hydraulic loss in the wall region. The comparison of hydraulic loss calculated by entropy production and pressure difference revealed a better result. Then, through the use of the entropy production theory, the performance characteristics were determined for a pump-turbine with 19 mm guide vane opening, and the variation in the entropy production was obtained. Recently, an interesting phenomenon, i.e., a hysteresis characteristic, was observed in the hump region in pump-turbines. Research shows that the hysteresis characteristic is a result of the Euler momentum and hydraulic loss; the hydraulic loss accounts for a major portion of the hysteresis characteristic. Finally, the hysteresis characteristic in the hump region was analyzed in detail through the entropy production. The results showed that the hump characteristic and the accompanying hysteresis phenomenon are caused by backflow at the runner inlet and the presence of separation vortices close to the hub and the shroud in the stay/guide vanes, which is dependent on the direction of

2012-01-01

Industrial production in high-wage countries like Germany is still at risk. Yet, there are many counter-examples in which producing companies dominate their competitors by not only compensating for their specific disadvantages in terms of factor costs (e.g. wages, energy, duties and taxes) but rather by minimising waste using synchronising integrativity as well as by obtaining superior adaptivity on alternating conditions. In order to respond to the issue of economic sustainability of industrial production in high-wage countries, the leading production engineering and material research scientists of RWTH Aachen University together with renowned companies have established the Cluster of Excellence “Integrative Production Technology for High-Wage Countries”. This compendium comprises the cluster’s scientific results as well as a selection of business and technology cases, in which these results have been successfully implemented into industrial practice in close cooperation with more than 30 companies of ...

These works focus on the development of attainment indices for nuclear hydrogen key technologies, the analysis of the hydrogen production process and the performance estimation for hydrogen production system, and the assessment of the nuclear hydrogen production economy. To estimate the attainments of the key technologies in progress with the performance goals of GIF, itemized are the attainment indices based on SRP published in VHTR R and D steering committee of Gen-IV. For assessing the degree of attainments in comparison with the final goals of VHTR technologies in progress of researches, subdivided are the prerequisite items conformed to the NHDD concepts established in a preconceptual design in 2005. The codes for analyzing the hydrogen production economy are developed for calculating the unit production cost of nuclear hydrogen. We developed basic R and D quality management methodology to meet design technology of VHTR's needs. By putting it in practice, we derived some problems and solutions. We distributed R and D QAP and Q and D QAM to each teams and these are in operation. Computer simulations are performed for estimating the thermal efficiency for the electrodialysis component likely to adapting as one of the hydrogen production system in Korea and EED-SI process known as the key components of the hydrogen production systems. Using the commercial codes, the process diagrams and the spread-sheets were produced for the Bunsen reaction process, Sulphuric Acid dissolution process and HI dissolution process, respectively, which are the key components composing of the SI process

Vaginal semisolid products are frequently used to treat vaginal infections and atrophy-related symptoms of menopause. Formulations composition and the methods for their characterization, especially those developed concerning the target epithelia, are key tools to predict in vivo results at early stages of product development. However, recent studies on this subject have been almost exclusively focused on anti-HIV preparations. The aim of this work consists on improving traditional characterization methods by using physiological parameters in order to construct predictive tools to characterize a new ideal vaginal semisolid formulation whatever target it may have. Ten vaginal antimicrobial and hormonal products already available in the market were studied (Gino-Canesten®, Sertopic®, Dermofix®, Gyno-pevaryl®, Lomexin®, Gino Travogen®, Dalacin V®, Ovestin®, Blissel®, Colpotrophine®). Furthermore, Universal Placebo gel and Replens® were used for comparison. Products were characterized in terms of: pH and buffering capacity in a vaginal fluid simulant (VFS); osmolality - directly and upon dilution in VFS; textural parameters (firmness, adhesiveness and bioadhesion) using vaginal ex vivo porcine epithelium; and viscosity (including VFS dilution at 37°C and after administration on an ex vivo model). Interestingly, the majority of the tested commercial vaginal formulations did not present technological characteristics close to the ideal ones when tested under target biological conditions. The inclusion of such methodologic adaptations is expected to optimize cost-efficiency of new formulations development by predicting efficacy and safety profiles at early stages of product development.

Harms on life environment, caused by aero pollution, for the last decades enforced fast development of technologies for filtration of gases that come from thermal power plants and other objects. SO 2 , that appear as one of outputs of fossil fuels combustion, and also processing of sulphide ore, is a main component of acid rains. Acid rains represent one of the most risky factors, responsible for dryne of woods and changing of flora and fauna on land and in water. Starting from 1931 year when on the thermal power plant BATTERSEA STATION, property of London Power, first scrubbers were monnted for filtration of flue gases of SO 2 , and up till today, many procedures are developed for desulfurization of flue gases. For easier coping with numerous technologies for desulfurization , various classifications were made. By state of aggregation of the absorption agent , the technologies for desulfurization of gases are divided in wet , semidry and dry procedures. Wet procedures are technologies with highness rate of desulfurization of 90-95 % and most flexible of the quality of fuel whose flue gases are filtered. Presently they have high price of 90-220 $/kw installed power. According to American sources, their price at the world market is forecasted that till 2000 year will reach price of 100 $/kw. Dry technologies for desulfurization of flue gases are last technologies. The rate of desulfurization is 50-60 % and its prise is 76 -113 $/kw. Their negative side is high variable costs 250 - 388 $/ ton SO 2 (at wet procedures variable costs 76 - 157 $/ton SO 2 ). Semidry technologies by financial and technological characteristics are wet and dry procedures. (Author)

The peculiarities of synthesis of biosurfactants by strains G. rubripertincta UCM Aс-122 and R. erythropolis Au-1 during the growth on the nutrient media with rape phosphatide concentrate as a carbon source was studied. Quantity of biomass was 9.4 – 10.1 g/l, exopoly mers –8.9-9.5 g/l and the content of cellbound trehalose lipids was 1.37 – 2.26 g/l; whereas the content of exogenous trehalose lipids –metabolites of R. erythropolis Au-1 was 2.95 g/l. It was found that the addition of trehalose lipids (0.01 g/l to the nutrient medium caused the increase of biomass on 14.6 –17.0 % and cell-bound lipids on 13.9 –15.5 %. Conclusions. Rape phosphatide concentrate is economically viable carbon source in the technologies of surfactant production by Actinobacteria. Its use promotes an increasing of exogenous surfactants strain R. erythropolisAu-1 in 3-fold compared with cultivation on nutrient medium with hexadecane. Trehalose lipids show a stimulating effect on growth and synthesis of biosurfactants by strains of G. rubripertincta UCM Ac-122 and R. erythropolisAu-1.

Technological feasibility of preserving meat, poultry and fish products by using a combination of conventional additives, mild heat treatment and irradiation

Radappertization is particularly applicable to precooked meat, poultry, fin fish, and shellfish, as well as to dry foods, animal feed, and spices. The resulting radappertized products are free from food spoilage microorganisms and organisms of public health significance, including the pathogens such as C. botulinum, salmonellae, trichinae, etc. The radappertized products can be stored without refrigeration for long periods (years), the limiting factor being the integrity of the primary packaging material. Irradiation sterilization of cured meats allows complete elimination or a drastic reduction of incoming nitrite to the levels needed only for characteristic colour and flavour of the items while providing protection against C. botulinum by irradiation. The irradiated-cured products with the low levels of added nitrite are free from residual nitrite and nitrosamines, including nitrosopyrrolidine in fried bacon. In recent co-operative research with the US Department of Agriculture, it was shown that irradiation also destroys pre-formed nitrosamines in bacon. The technology of the process was developed by the US National Food Irradiation Program and the US Army from 1953 to 1980. The US Army spearheaded the development of this new technology to the point where the food irradiation potentials have become meaningful within the broad scope of national and international interests. Therefore, it was highly appropriate that, effective 1 October 1980, the responsibility for the programme at this stage was transferred to the US Department of Agriculture which has been designated as the leading agency for the US Federal food and nutrition programmes

2007-11-01

The molten salt waste from a pyroprocess to recover uranium and transuranic elements is one of the problematic radioactive wastes to be solidified into a durable wasteform for its final disposal. By using a novel method, named as the GRSS (gel-route stabilization/solidification) method, a molten salt waste was treated to produce a unique wasteform. A borosilicate glass as a chemical binder dissolves the silicate compounds in the gel products to produce one amorphous phase while most of the phosphates are encapsulated by the vitrified phase. Also, Cs in the gel product is preferentially situated in the silicate phase, and it is vitrified into a glassy phase after a heat treatment. The Sr-containing phase is mainly phosphate compounds and encapsulated by the glassy phase. These phenomena could be identified by the static and dynamic leaching test that revealed a high leach resistance of radionuclides. The leach rates were about 10(-3) - 10(-2) g/m2 x day for Cs and 10(-4) - 10(-3) g/m2 x day for Sr, and the leached fractions of them were predicted to be 0.89% and 0.39% at 900 days, respectively. This paper describes the characteristics of a unique wasteform containing a molten salt waste and provides important information on a newly developed immobilization technology for salt wastes, the GRSS method.

E-detailing involves using digital technology, such as Internet, video conferencing, and interactive voice response, by which drug companies target their marketing efforts toward specific physicians with pinpoint accuracy. A mail survey of 671 Iowa physicians was used to gather information about the physician characteristics and practice setting characteristics of those who are usually targeted by pharmaceutical companies to participate in e-detailing. A model is developed and tested to explain firms' targeting strategy for targeting physicians for e-detailing.

Opportunities, perspectives and limits in lactic acid production from waste and industrial by-products

Directory of Open Access Journals (Sweden)

Mladenović Dragana D.

2016-01-01

Full Text Available In line with the goals of sustainable development and environmental protection today great attention is directed towards new technologies for waste and industrial by-products utilization. Waste products represent potentially good raw material for production other valuable products, such as bioethanol, biogas, biodiesel, organic acids, enzymes, microbial biomass, etc. Since the first industrial production to the present, lactic acid has found wide application in food, cosmetic, pharmaceutical and chemical industries. In recent years, the demand for lactic acid has been increasing considerably owing to its potential use as a monomer for the production of poly-lactic acid (PLA polymers which are biodegradable and biocompatible with wide applications. Waste and industrial by-products such are whey, molasses, stillage, waste starch and lignocellulosic materials are a good source of fermentable sugars and many other substances of great importance for the growth of microorganisms, such as proteins, minerals and vitamins. Utilization of waste products for production of lactic acid could help to reduce the total cost of lactic acid production and except the economic viability of the process offers a solution of their disposal. Fermentation process depends on chemical and physical nature of feedstocks and the lactic acid producer. This review describes the characteristics, abilities and limits of microorganisms involved in lactic acid production, as well as the characteristics and types of waste products for lactic acid production. The fermentation methods that have been recently reported to improve lactic acid production are summarized and compared. In order to improve processes and productivity, fed-batch fermentation, fermentation with immobilized cell systems and mixed cultures and opportunities of open (non-sterilized fermentation have been investigated.

Ethanol production in China: Potential and technologies

International Nuclear Information System (INIS)

Li, Shi-Zhong; Chan-Halbrendt, Catherine

2009-01-01

Rising oil demand in China has resulted in surging oil imports and mounting environmental pollution. It is projected that by 2030 the demand for fossil fuel oil will be 250 million tons. Ethanol seems to be an attractive renewable alternative to fossil fuel. This study assesses China's ethanol supply potential by examining potential non-food crops as feedstock; emerging conversion technologies; and cost competitiveness. Results of this study show that sweet sorghum among all the non-food feedstocks has the greatest potential. It grows well on the available marginal lands and the ASSF technology when commercialized will shorten the fermentation time which will lower the costs. Other emerging technologies such as improved saccharification and fermentation; and cellulosic technologies will make China more competitive in ethanol production in the future. Based on the estimated available marginal lands for energy crop production and conversion yields of the potential feedstocks, the most likely and optimistic production levels are 19 and 50 million tons of ethanol by 2020. In order to achieve those levels, the roadmap for China is to: select the non-food feedstock most suitable to grow on the available marginal land; provide funding to support the high priority conversion technologies identified by the scientists; provide monetary incentives to new and poor farmers to grow the feedstocks to revitalize rural economy; less market regulation and gradual reduction of subsidies to producers for industry efficiency; and educate consumers on the impact of fossil fuel on the environment to reduce consumption. Since the share of ethanol in the overall fuel demand is small, the impact of ethanol on lowering pollution and enhancing fuel security will be minimal. (author)

Risk-Optimized Design of Production Systems by Use of GRAMOSA

Directory of Open Access Journals (Sweden)

Michael Lütjen

2014-01-01

Full Text Available Today production and logistic systems are getting more complex. This is a problem which the planning and design of such systems have to deal with. One main issue of production system development in series production is the planning of production processes and systems under uncertainty. New and existing production technologies are often not fully adoptable to new products. This is why some of the main characteristics, like, for example, cost, time, or quality, are not definable at the beginning. Only value ranges and probabilities can be estimated. However, the adaptation process is controllable, which means that the adaptation results are depending on the existing development budget and its resources. This paper presents an approach for the optimized allocation of development resources regarding the adaptation risks of production technologies and processes. The modeling concept GRAMOSA is used for integrated modeling and discrete event-based simulation of the aspired production system. To this end a domain-specific modeling language (DSML is applied. The further risk-based analysis of the simulation results and the optimized allocation of the development budget are done by use of mathematical optimization.

Full Text Available In a knitting factory, any activity oriented toward evaluation, maintenance or improvement of products quality level is based on measuring and examining the product quality characteristics, in order to establish conformity to the quality specifications and/or naming the non-quality characteristics, thus noticing defects or fabrication deficiencies. The quality of the stitching operation has a particular influence on the finite product quality and is determined on side by the quality of knitted pieces, and on the other by insuring the correlation between the technological parameters of the stitching operation and the physico-mechanical characteristics of the knittings that are to be assembled through stitching. Although the product execution processes comprise of manufacturing the elements and distinct subassemblies and their ulterior assembly, they present various difference dictated by the constructive particularities of the machine, as well as fabric characteristics. Because of the multiple interactions between the material, yarn and working parts of the sawing machine, inadequacies in the technological discipline can result in negative effects on both the knitted and stitching thread as well as the machine. A part of these can be fixed by extra time consuming tasks (yarn breaks, stitching ruffling etc., while other defects appear during the usage of the product cheapening it (stitch tearing by perforating the knitted on the stitching line, pilling effect, dimensional instability etc.. This paper systematically presents, the main defects that may occur during the stitching operation of the products made out of circular knitted, as well as the causes that generate them along with preventive or corrective actions.

Translational science by public biotechnology companies in the IPO "class of 2000": the impact of technological maturity.

Science.gov (United States)

McNamee, Laura; Ledley, Fred

2013-01-01

The biotechnology industry plays a central role in the translation of nascent biomedical science into both products that offer material health benefits and creating capital growth. This study examines the relationship between the maturity of technologies in a characteristic life cycle and value creation by biotechnology companies. We examined the core technology, product development pipelines, and capitalization for a cohort of biotechnology companies that completed an IPO in 2000. Each of these companies was well financed and had core technologies on the leading edge of biological science. We found that companies with the least mature technologies had significantly higher valuations at IPO, but failed to develop products based on these technologies over the ensuing decade, and created less capital growth than companies with more mature technologies at IPO. The observation that this cohort of recently public biotechnology companies was not effective in creating value from nascent science suggests the need for new, evidence-based business strategies for translational science.

What environmental factors stimulate and maintain research productivity? To answer this question, the authors conducted an extensive review of articles and books on research productivity published from the mid-1960s through 1990. This review revealed that a consistent set of 12 characteristics was found in research-conducive environments: (1) clear goals that serve a coordinating function, (2) research emphasis, (3) distinctive culture, (4) positive group climate, (5) assertive participative governance, (6) decentralized organization, (7) frequent communication, (8) accessible resources, particularly human, (9) sufficient size, age, and diversity of the research group, (10) appropriate rewards, (11) concentration on recruitment and selection, and (12) leadership with research expertise and skill in both initiating appropriate organizational structure and using participatory management practices. Some of these characteristics are not surprising, although some findings were unexpected, such as that participative governance correlated consistently with research productivity. The differential impact of each of these 12 characteristics is unclear. It is clear, however, that the leader has a disproportionate impact through his or her influence on all of the other characteristics. Yet, an overarching feature of these characteristics is their interdependency. These factors do not operate in research groups as isolated characteristics. Rather, they are like fine threads of a whole fabric: individual, yet when interwoven, providing a strong, supportive, and stimulating backdrop for the researcher. The authors conclude that while at a distance the productive research enterprise looks like a highly robust entity, upon closer inspection it is revealed to be a delicate structure highly dependent on the existence and effective working of numerous individual, organizational, and leadership characteristics.

Full Text Available The article is aimed at studying the characteristics of susceptibility of innovative products in the domestic economy. On the example of the mobile communications market, an analysis of the diffusion of innovations and their acceptance in the context of business cycle has been carried out. On the basis of the mentioned analysis has been determined that the difference between the time of invention of a new product or technology and the time of its application, as well as diffusion into the domestic economy, is connected with different trajectories of business cycle. A comparative analysis of competitive advantages in the implementation of innovation in Finland, Switzerland and Ukraine was carried out through the prism of the factors, which determine the competitiveness of innovations, and the factors, which are not conducive to the implementation of entrepreneurial activity. It has been determined that entrepreneurial activity in the leading countries is most hampered by economic factors, and in Ukraine – by social and political factors. The low innovative capacity compared with Finland and Switzerland in the domestic economy is associated with a weak innovation infrastructure.

Production of drug-loaded polymeric nanoparticles by electrospraying technology.

Sosnik, Alejandro

2014-09-01

The pharmaceutical industry struggles with high attrition. The outbreak of pharmaceutical micro/nanotechnology has been fundamental to overcome several (bio)pharmaceutic drawbacks of drugs such as poor aqueous solubility, physicochemical instability, short half life, inappropriate biodistribution and toxicity. The spatiotemporal release of drugs directly in the site of action and the restriction of the systemic exposure by means of nanotechnology has notoriously improved drug safety ratios. At the same time, the development of production methods that are cost-effective, scalable and reproducible under industrial settings becomes crucial to ensure the clinical translation of any development. The electrospraying process, also known as electrohydrodynamic atomization (EHDA), is a single-stage technique of liquid atomization by means of electrical forces that enables the generation of micro/nanoparticles with especially narrow size distribution. EHDA is based on the ability of an electric field to deform the interface of a liquid drop and break it into smaller mono-disperse droplets. The main advantageous features over conventional methods are the possibility to produce particles without the use of surfactants, at ambient temperature and pressure and with maximum encapsulation efficiency due to the absence of an external medium that allows the migration and/or dissolution of water-soluble cargos. In addition, the mild conditions are optimal for the encapsulation of thermo-sensitive cargos. The present article overviews the applications of this technology for the production of nano-drug delivery systems and discusses its key role to support the transfer of a broad spectrum of nanomedicines to the market.

Hydrogen fuel is a potentially major solution to the problem of climate change, as well as addressing urban air pollution issues. But a key future challenge for hydrogen as a clean energy carrier is a sustainable, low-cost method of producing it in large capacities. Most of the world's hydrogen is currently derived from fossil fuels through some type of reforming processes. Nuclear hydrogen production is an emerging and promising alternative to the reforming processes for carbon-free hydrogen production in the future. This report presents the main results of a research program carried out by a NERI Consortium, which consisted of Penn State University (PSU) (lead), University of South Carolina (USC), Tulane University (TU), and Argonne National Laboratory (ANL). Thermochemical water decomposition is an emerging technology for large-scale production of hydrogen. Typically using two or more intermediate compounds, a sequence of chemical and physical processes split water into hydrogen and oxygen, without releasing any pollutants externally to the atmosphere. These intermediate compounds are recycled internally within a closed loop. While previous studies have identified over 200 possible thermochemical cycles, only a few have progressed beyond theoretical calculations to working experimental demonstrations that establish scientific and practical feasibility of the thermochemical processes. The Cu-Cl cycle has a significant advantage over other cycles due to lower temperature requirements – around 530 °C and below. As a result, it can be eventually linked with the Generation IV thermal power stations. Advantages of the Cu-Cl cycle over others include lower operating temperatures, ability to utilize low-grade waste heat to improve energy efficiency, and potentially lower cost materials. Another significant advantage is a relatively low voltage required for the electrochemical step (thus low electricity input). Other advantages include common chemical agents and

Full Text Available The effect of four storage temperature modes (6, 12, 20 and 30 °C on sensory properties of chocolate products and their colour changes in the experiment over a period of 6 months. The results were evaluated with regard to the production technology and composition of chocolate products. The experiment was performed on filled milk chocolate product called Orion Pistachio made in four versions such as a standard containing cocoa mass of 35 % referred to retempered variant (RS and not treated by retempering (NS variant and with higher proportion of cocoa mass (45 % stated as retempered variant (R45 and not treated by retempering (N45 variant. Retempering means the exposure of products for 24 hours at 24 °C immediately after the production and packaging. The results show that the technology of retempering can effectively increase the resistance of chocolate products to the fat bloom as reflected in the improved colour stability. Sensory most acceptable products were stored at 6 and 12 °C throughout the experiment.

2017-12-01

Full Text Available The promise of industrial biotechnology has been around since Chaim Weizmann developed acetone–butanol–ethanol fermentation at the University of Manchester in 1917 and the prospects nowadays look brighter than ever. Today’s biorefinery technologies would be almost unthinkable without biotechnology. This is a growing trend and biorefineries have also increased in importance in agriculture and the food industry. Novel biorefinery processes using solid state fermentation (SSF technology have been developed as alternative to conventional processing routes, leading to the production of added-value products from agriculture and food industry raw materials. SSF involves the growth of microorganisms on moist solid substrate in the absence of free-flowing water. Future biorefineries based on SSF aim to exploit the vast complexity of the technology to modify biomass produced by agriculture and the food industry for valuable by-products through microbial bioconversion. In this review, a summary has been made of the attempts at using modern microbial SSF technology for future biorefineries for the production of many added-value products ranging from feedstock for the fermentation process and biodegradable plastics to fuels and chemicals.

This contribution describes a continuous process for the production of solid lipid nanoparticles (SLN) as drug-carrier systems via hot-melt extrusion (HME). Presently, HME technology has not been used for the manufacturing of SLN. Generally, SLN are prepared as a batch process, which is time consuming and may result in variability of end-product quality attributes. In this study, using Quality by Design (QbD) principles, we were able to achieve continuous production of SLN by combining two processes: HME technology for melt-emulsification and high-pressure homogenization (HPH) for size reduction. Fenofibrate (FBT), a poorly water-soluble model drug, was incorporated into SLN using HME-HPH methods. The developed novel platform demonstrated better process control and size reduction compared to the conventional process of hot homogenization (batch process). Varying the process parameters enabled the production of SLN below 200 nm. The dissolution profile of the FBT SLN prepared by the novel HME-HPH method was faster than that of the crude FBT and a micronized marketed FBT formulation. At the end of a 5-h in vitro dissolution study, a SLN formulation released 92-93% of drug, whereas drug release was approximately 65 and 45% for the marketed micronized formulation and crude drug, respectively. Also, pharmacokinetic study results demonstrated a statistical increase in Cmax, Tmax, and AUC0-24 h in the rate of drug absorption from SLN formulations as compared to the crude drug and marketed micronized formulation. In summary, the present study demonstrated the potential use of hot-melt extrusion technology for continuous and large-scale production of SLN.

Biomass Gasification. The characteristics of technology development and the rate of learning

Energy Technology Data Exchange (ETDEWEB)

. In the case of large scale, interest has shifted from electricity generation to biofuel production, primarily due to the failed demonstration projects of the technology coupled with combined cycle for electricity generation. On the other hand, in small scale projects, cogeneration applications have gained interest over heat production. However, there are fewer actors involved in small scale experimentation than in large scale. Once the specific situation of each country has been analyzed, and the main characteristics of the development process have been identified, one of the causes which have hindered the technology to reach the expected commercial stage has been the lack of resources to demonstrate its competitiveness. So far, a significant number of experimentation activities, based on demonstration projects and pilot plants, have proved the future potential of the technology. Nonetheless, the uncertainty, shown by the great majority of actors, about integrating the biomass gasification in their industrial process has hindered the demonstration of its operational feasibility. Following this, further efforts should focus on the creation of incentives for the construction of new plants which integrate this technology in an industrial process already consolidated in the market. An approximation of the number of new plants needed, could be a good indicator of the economical resources required in order to acquire enough experience to make biomass gasification a competitive technology in the short-term. After simulating various future evolutions for small scale cogeneration applications, the learning rate obtained through the learning curves model predict that, building roughly forty plants in six years, the technology can be consolidated firmly in the market. Considering the decrease in the number of new plants built since 2002, the expectancies are not really optimistic. Nevertheless, it is not an unachievable objective if incentives are created by all administrative

Food product tracing technology capabilities and interoperability.

Bhatt, Tejas; Zhang, Jianrong Janet

Despite the best efforts of food safety and food defense professionals, contaminated food continues to enter the food supply. It is imperative that contaminated food be removed from the supply chain as quickly as possible to protect public health and stabilize markets. To solve this problem, scores of technology companies purport to have the most effective, economical product tracing system. This study sought to compare and contrast the effectiveness of these systems at analyzing product tracing information to identify the contaminated ingredient and likely source, as well as distribution of the product. It also determined if these systems can work together to better secure the food supply (their interoperability). Institute of Food Technologists (IFT) hypothesized that when technology providers are given a full set of supply-chain data, even for a multi-ingredient product, their systems will generally be able to trace a contaminated product forward and backward through the supply chain. However, when provided with only a portion of supply-chain data, even for a product with a straightforward supply chain, it was expected that interoperability of the systems will be lacking and that there will be difficulty collaborating to identify sources and/or recipients of potentially contaminated product. IFT provided supply-chain data for one complex product to 9 product tracing technology providers, and then compared and contrasted their effectiveness at analyzing product tracing information to identify the contaminated ingredient and likely source, as well as distribution of the product. A vertically integrated foodservice restaurant agreed to work with IFT to secure data from its supply chain for both a multi-ingredient and a simpler product. Potential multi-ingredient products considered included canned tuna, supreme pizza, and beef tacos. IFT ensured that all supply-chain data collected did not include any proprietary information or information that would otherwise

Full Text Available Salt production in the Mixteca Alta is a traditional means of production from prehispanic period, which, despite the economic transformation processes in the colonial period, remained significant features of the traditional process, based on the documented similar models from other productive regions in Mexico. The salt in the novohispanic period was considered a major consumption economic asset due to its use in production processes for the production of new economic products that supported the economy of preindustrial societies (Terán, 2011, p. 71; Williams, 2008. Technology refers to the knowledges for solving human needs arising lifestyle of the cultural groups that develop them. The resources of the natural environment underpin the means of labor that man requires to perform its activities, including economic. The means of production and production processes are technological developments, which involve elements of tangible and intangible order. The study of work processes for salt extraction, are significantly related to the processes of technological evolution that man has developed for the use of natural resources. The economic activities of the primary sector are examples of how humans culturally and economically were inserted in the natural environment (Malpica, 2008, p. 59. This analysis presents a historiographical approach to the study of the processes and the technology required for the extraction of salt in the Mixteca Alta.

In the last decade a production of charcoal and products from charcoal has been taking on an important position in a field of environmental technologies. Technological process of the production of charcoal is accompanied by formation of fluid and gaseous elements. These elements are ranked as pollutants from the legal point of view. There are mainly carbon dioxide and carbon monoxide and other oxide compounds from the chemical point of view. Particularly acetic acid, methanol, 2-furaldehyde. Then aliphatic alcohols, phenols, aldehydes, ketones, esters and other groups of substances. Law limits the quantity and concentration of these essentials emitted into the open air. This matter has to be taken care of during the production of charcoal. It is usually solved by condensation cooling and following burning gases and steams. Condensate is industrially processed or smaller technologies handle with it similar to taking care of wastewater. (authors)

New blue pigment produced by Pantoea agglomerans and its production characteristics at various temperatures.

Science.gov (United States)

Fujikawa, Hiroshi; Akimoto, Ryo

2011-01-01

A bacterium capable of producing a deep blue pigment was isolated from the environment and identified as Pantoea agglomerans. The pigment production characteristics of the bacterium under various conditions were studied. The optimal agar plate ingredients for pigment production by the bacterium were first studied: the optimal ingredients were 5 g/liter glucose, 10 g/liter tryptic soy broth, and 40 g/liter glycerol at pH 6.4. Bacterial cells grew on the agar plate during the incubation, while the pigment spread into the agar plate, meaning that it is water soluble. Pigment production was affected by the initial cell density. Namely, at higher initial cell densities ranging from 10(6.3) to 10(8.2) CFU/cm(2) on the agar plate, faster pigment production was observed, but no blue pigment was produced at a very high initial density of 10(9.1) CFU/cm(2). Thus, the cell population of 10(8.2) CFU/cm(2) was used for subsequent study. Although the bacterium was capable of growing at temperatures above and below 10°C, it could produce the pigment only at temperatures of ≥10°C. Moreover, the pigment production was faster at higher temperatures in the range of 10 to 20°C. Pigment production at various temperature patterns was well described by a new logistic model. These results suggested that the bacterium could be used in the development of a microbial temperature indicator for the low-temperature-storage management of foods and clinical materials. To our knowledge, there is no other P. agglomerans strain capable of producing a blue pigment and the pigment is a new one of microbial origin.

Development of aromatic VOC control technology by electron beam hybrid

International Nuclear Information System (INIS)

Kim, Jo-Chun; Kim, Ki-Joon

2006-01-01

As a fundamental study, the decomposition of volatile organic compounds (VOCs) using electron beam (EB) irradiation has been extensively investigated. EB treatments of VOCs such as toluene and styrene are discussed. The degradation characteristics were intensively investigated under various concentrations and irradiation doses to determine and improve VOC removal efficiencies. This work illustrates that the removal efficiencies of aromatic VOCs generally increase as their concentrations decrease and the irradiation doses increase. Based on these basic studies, it was found that by-products produced from EB irradiation of VOCs would cause a secondary pollution problem. Therefore, a novel hybrid technology has been applied to control aromatic VOC emissions by annexing the catalyst technique with conventional treatment study using EB technology. The experiments were carried out using a bench-scale at first, then a pilot-scale system was followed. Toluene was selected as a typical VOC for EB hybrid control to investigate by-products, effects of ceramic and catalyst, and factors affecting overall efficiency of degradation. It was concluded that VOCs could be destroyed more effectively by a novel hybrid system than single EB irradiation. (author)

Laser aided direct metalimaterial deposition (DMD) process builds metallic parts layer-by-layer directly from the CAD representation. In general, the process uses powdered metaUmaterials fed into a melt pool, creating fully dense parts. Success of this technology in the die and tool industry depends on the parts quality to be achieved. To obtain designed geometric dimensions and material properties, delicate control of the parameters such as laser power, spot diameter, traverse speed and powder mass flow rate is critical. In this paper, the dimensional and material characteristics of directed deposited H13 tool steel by CO II laser are investigated for the DMD process with a feedback height control system. The relationships between DMD process variables and the product characteristics are analyzed using statistical techniques. The performance of the DMD process is examined with the material characteristics of hardness, porosity, microstructure, and composition.

2017-04-01

Full Text Available The increasing prevalence of coeliac disease (CD and gluten-related disorders has led to increasing consumer demand for gluten-free products with quality characteristics similar to wheat bread. The replacement of gluten in cereal-based products remains a challenge for scientists, due to its unique role in network formation, which entraps air bubbles. When gluten is removed from a flour, starch is the main component left. Starch is used as gelling, thickening, adhesion, moisture-retention, stabilizing, film forming, texturizing and anti-staling ingredient. The extent of these properties varies depending on the starch source. The starches can additionally be modified increasing or decreasing certain properties of the starch, depending on the application. Starch plays an important role in the formulation of bakery products and has an even more important role in gluten-free products. In gluten-free products, starch is incorporated into the food formulation to improve baking characteristics such as the specific volume, colour and crumb structure and texture. This review covers a number of topics relating to starch; including; an overview of common and lesser researched starches; chemical composition; morphology; digestibility; functionality and methods of modification. The emphasis of this review is on starch and its properties with respect to the quality of gluten-free products.

Environmental control technology in petroleum drilling and production

International Nuclear Information System (INIS)

Wojtanowicz, A.K.

1997-01-01

Environmental control technology (ECT) is process integrated and relates mainly to pollution prevention and risk assessment. Mechanisms of environmental impact in petroleum drilling, well completion and production, include the generation of waste, induction of toxicity or the creation of pathways for pollutant migration. The identification and evaluation of these mechanisms constitute two parts of the scope of ECT. A third part is the development of new techniques to comply with environmental requirements without prejudicing productivity. The basic concepts of the ECT approach are presented in this chapter. The approach is then used to analyse oilfield drilling and production processes. Environmental control components developed in these technologies are described. These include: the control of the volume and toxicity of drilling fluids; source separation technology in produced water cleaning; subsurface injection of oilfield waste slurries; containment technology in the integrity of petroleum wells; subsurface reduction of produced water; oilfield pit closure technology.

2017-12-01

Full Text Available From its beginnings, up to a few years ago, additive manufacturing technology was able to produce models or prototypes which have limited use, because of materials mechanical properties. With advancement and invention of new materials, this is changing. Now, it is possible to create 3D prints that can be used as final products or functional tools, using technology and materials with low environmental impact. The goal of this study was to examine opportunities for production of paper embossing tools by fused deposition modelling (FDM 3D printing. This study emphasises the use of environmentally friendly poly-lactic acid (PLA materials in FDM technology, contrary to the conventional method using metal alloys and acids. Embossing of line elements and letters using 3D printed embossing tools was done on six different types of paper. Embossing force was applied using SHIMADZU EZ-LX Compact Tabletop Testing Machine. Each type of paper was repeatedly embossed using different values of embossing force (in 250 N increments, starting at 1000 N to determine the optimal embossing force for each specific paper type. When determined, the optimal embossing force was used on ten samples for each paper type. Results of embossing were analysed and evaluated. The analysis consisted of investigating the effects of the applied embossing force and characteristics such as paper basis weight, paper structure, surface characteristic and fibre direction of the paper. Results show that paper characteristics determine the embossing force required for achieving a good embossing result. This means that with the right amount of embossing force, letters and borderlines can be equally well formed by the embossing process regardless of paper weight, surface characteristics, etc. Embossing tools produced in this manner can be used in case of the embossing elements that are not complex. The reason for this is the limitation of FDM technology and lack of precision needed for fine

Say Kong Ng

2013-04-01

Full Text Available From 2006 to 2011, an average of 15 novel recombinant protein therapeutics have been approved by US Food and Drug Administration (FDA annually. In addition, the expiration of blockbuster biologics has also spurred the emergence of biosimilars. The increasing numbers of innovator biologic products and biosimilars have thus fuelled the demand of production cell lines with high productivity. Currently, mammalian cell line development technologies used by most biopharmaceutical companies are based on either the methotrexate (MTX amplification technology or the glutamine synthetase (GS system. With both systems, the cell clones obtained are highly heterogeneous, as a result of random genome integration by the gene of interest and the gene amplification process. Consequently, large numbers of cell clones have to be screened to identify rare stable high producer cell clones. As such, the cell line development process typically requires 6 to 12 months and is a time, capital and labour intensive process. This article reviews established advances in protein expression and clone screening which are the core technologies in mammalian cell line development. Advancements in these component technologies are vital to improve the speed and efficiency of generating robust and highly productive cell line for large scale production of protein therapeutics.

Piesse, J; Thirtle, C

2010-09-27

The relationships between basic and applied agricultural R&D, developed and developing country R&D and between R&D, extension, technology and productivity growth are outlined. The declining growth rates of public R&D expenditures are related to output growth and crop yields, where growth rates have also fallen, especially in the developed countries. However, growth in output value per hectare has not declined in the developing countries and labour productivity growth has increased except in the EU. Total factor productivity has generally increased, however it is measured. The public sector share of R&D expenditures has fallen and there has been rapid concentration in the private sector, where six multinationals now dominate. These companies are accumulating intellectual property to an extent that the public and international institutions are disadvantaged. This represents a threat to the global commons in agricultural technology on which the green revolution has depended. Estimates of the increased R&D expenditures needed to feed 9 billion people by 2050 and how these should be targeted, especially by the Consultative Group on International Agricultural Research (CGIAR), show that the amounts are feasible and that targeting sub-Saharan Africa (SSA) and South Asia can best increase output growth and reduce poverty. Lack of income growth in SSA is seen as the most insoluble problem.

In the present study, a graded ethanol precipitation technique was employed to obtain hemicelluloses from the alkali-extracted corncob liquid. The relationship between the structural characteristics of alkali-soluble corncob hemicelluloses and the production of furfural was investigated by a heterogeneous process in a biphasic system. Results showed that alkali-soluble corncob hemicelluloses mainly consisted of glucuronoarabinoxylans and L-arabino-(4-O-methylglucurono)-D-xylans, and the drying way had less influence on the sugar composition, molecular weights and the functional groups of hemicelluloses obtained by the different ethanol concentration precipitation except for the thermal property, the amorphous structure and the ability for the furfural production. Furthermore, alkali-soluble corncob hemicelluloses with higher xylose content, lower branch degree, higher polydispersity and crystallinity contributed to the furfural production. A highest furfural yield of 45.41% with the xylose conversion efficiency of 99.06% and the furfural selectivity of 45.84% was obtained from the oven-dried hemicelluloses precipitated at the 30% (v/v) ethanol concentration.

Technological change is often seen as the promising device that will mitigate or solve environmental problems. Policy intervention that spurs the development, adoption and diffusion of new, environmentally benign technologies therefore holds great appear for environmental authorities. Policymakers have various instruments at their disposal to affect technological diffusion, ranging from direct regulation (command-and-control strategies) to market-based instruments, such as taxes, subsidies and tradable pollution permits. This paper examines environmental subsidies as a technology diffusion policy. The authors apply evolutionary game theory to explore the relationship between subsidies for clean technology, the diffusion of that technology and the degree of product differentiation in an imperfectly competitive market. They show that the subsidy succeeds in reducing environmental damage only when the substitution effect (the reduction in pollution associated with the clean technology) exceeds the output effect (the extent that the subsidy increases output). When the substitution effect does dominate, environmental damage decreases monotonically during the diffusion process. The extent of diffusion (the degree to which clean technolgy replaces dirty) and the likelihood that the substitution effect will dominate both decrease with the extent of product differentiation. Finally, the subsidy for clean technology will spill over to the remaining dirty producers increasing their profit as well.

ISO26000:2010 International Guidance Standard on Organizational Social Responsibility requires that effective organizational performance recognize social responsibility, including the rights of persons with disabilities (PWD), engage stakeholders and contribute to sustainable development. Millennium Development Goals 2010 notes that the most vulnerable people require special attention, while the World Report on Disability 2011 identifies improved data collection and removal of barriers to rehabilitation as the means to empower PWD. The Assistive Technology Device Classification (ATDC), Assistive Technology Service Method (ATSM) and Matching Person and Technology models provide an evidence-based, standardized, internationally comparable framework to improve data collection and rehabilitation interventions. The ATDC and ATSM encompass and support universal design (UD) principles, and use the language and concepts of the International Classification of Functioning, Disability and Health (ICF). Use ATDC and ICF concepts to differentiate medical, assistive and UD products and technology; relate technology "types" to markets and costs; and support provision of UD products and technologies as sustainable and socially responsible behavior. Supply-side and demand-side incentives are suggested to foster private sector development and commercialization of UD products and technologies. Health and health-related professionals should be knowledgeable of UD principles and interventions.

Production of hydrogen from by-products of food industries by rhodospirillaceae

Energy Technology Data Exchange (ETDEWEB)

Reh, U.

1983-11-01

The decomposition of organic substances from food-by-products as whey, beet sugar molasses, cane-sugar-molasses and potato-water by the Rhodospirillaceae Rp. capsulata, Rp. acidophila, Rm. vannielii, Rs. rubrum, and Rs. tenue to hydrogen and carbon dioxide were tested. In a pre-cultivation Lactobacillus bulgaricus converted the sugars of the by-products into lactic acid, which is easier in handling. Rs. rubrum was superior in producing hydrogen from this nutrient. It released from whey up to 56% of the substrate hydrogen, from beet sugar molasses 42%, from cane-sugar-molasses 89% and from potato-water 19%. Out-door-researches were made to evaluate the decrease of hydrogen yield under the influence of weather as well as day and night periods compared to the homogeneous conditions of the laboratory. From 200 m/sup 3/ whey, the daily output of a dairy, 4000 m/sup 3/ hydrogen corresponding to an energy equivalent of 1000 l fuel oil could be produced. To achieve this, 130 000 m/sup 2/ have to be covered with batch fermenters. These results show, that there is nearly no hope to decompose food by-products by Rhodospirillaceae in large scale technology, unless a new processing technology using a flow-fermenter and raising the hydrogen production significantly will be found.

Gibson, Grant; Newton, Lisa; Pritchard, Gary; Finch, Tracy; Brittain, Katie; Robinson, Louise

2016-07-01

In this review we explore the provision of assistive technology products and services currently available for people with dementia within the United Kingdom. A scoping review of assistive technology products and services currently available highlighted 171 products or product types and 331 services. In addition, we assimilated data on the amount and quality of information provided by assistive technology services alongside assistive technology costs. We identify a range of products available across three areas: assistive technology used 'by', 'with' and 'on' people with dementia. Assistive technology provision is dominated by 'telecare' provided by local authorities, with services being subject to major variations in pricing and information provision; few currently used available resources for assistive technology in dementia. We argue that greater attention should be paid to information provision about assistive technology services across an increasingly mixed economy of dementia care providers, including primary care, local authorities, private companies and local/national assistive technology resources. © The Author(s) 2014.

In addition, jatropha trees are commonly cut down to a height of 45 cm once every 10 years, with a production of 80 t·ha−1 of dry matter of woody biomass. The use of this biomass has not yet been investigated. During the European project JatroMed, woody biomass from jatropha pruning was collected in Morocco. Chemical and physical characteristics of the wood were conducted according to UNI EN ISO standards. The following jatropha wood characteristics have been analyzed: Moisture and ash contents, the ash melting point, heating value, and concentrations of C, H, N, and S. This research focused on the evaluation of the potential use of jatropha pruning for energy production, and the results represent critical data that is useful for future studies and business potential.

Nano-formulation of poorly water-soluble drugs has been developed to enhance drug dissolution. In this review, we introduce nano-milling technology described in recently published papers. Factors affecting the size of drug crystals are compared based on the preparation methods and drug and excipient types. A top-down approach using the comminution process is a method conventionally used to prepare crystalline drug nanoparticles. Wet milling using media is well studied and several wet-milled drug formulations are now on the market. Several trials on drug nanosuspension preparation using different apparatuses, materials, and conditions have been reported. Wet milling using a high-pressure homogenizer is another alternative to preparing production-scale drug nanosuspensions. Dry milling is a simple method of preparing a solid-state drug nano-formulation. The effect of size on the dissolution of a drug from nanoparticles is an area of fundamental research, but it is sometimes incorrectly evaluated. Here, we discuss evaluation procedures and the associated problems. Lastly, the importance of quality control, process optimization, and physicochemical characterization are briefly discussed.

These works focus on the development of attainment indices for nuclear hydrogen key technologies, the analysis of the hydrogen production process and the performance estimation for hydrogen production systems, and the assessment of the nuclear hydrogen production economy. The codes for analyzing the hydrogen production economy are developed for calculating the unit production cost of nuclear hydrogen. We developed basic R and D quality management methodology to meet design technology of VHTR's needs. By putting it in practice, we derived some problems and solutions. We distributed R and D QAP and Q and D QAM to each teams and these are in operation. Computer simulations are performed for estimating the thermal efficiency for the electrodialysis component likely to adapting as one of the hydrogen production system in Korea and EED-SI process known as the key components of the hydrogen production systems. Using the commercial codes, the process diagrams and the spread-sheets were produced for the Bunsen reaction process, Sulphuric Acid dissolution process and HI dissolution process, respectively, which are the key components composing of the SI process

A new production method is presented allowing the production of bulk quantities of fullerenes and other carbon nanomaterials using a 3-phase thermal plasma (260 kW). The main characteristics of this method lie in the independent control of the carbon throughput by injection of a solid carbon feedstock, and the immediate extraction of the synthesised product from the reactor, allowing production on a continuous basis. The currently investigated plasma facility is of an intermediate scale between lab-size and an industrial pilot plant, ready for further up scaling to an industrial size. The influence of a large number of different carbon precursors, plasma gases and operating conditions on the fullerene yield has been studied. At this state, quantities of up to 1 kg of carbon can be processed per hour with further scope for increase, leading to production rates for this type of materials not achievable with any other technology at present

Full Text Available The aim of the research was to learn from a survey about the production and economic characteristics of sheep production as well as economic position and developmental orientation of sheep breeders on the island of Pag. Data on production and economic characteristics of sheep production on the island of Pag were collected from a survey and processed through relevant descriptive statistics methods. The respondents have on average 47 breeding sheep, 2 rams and 9 sheep intended for flock renewal rate (not older than one year; which means an average flock has 58 sheep. The average total income from sheep production in 2009 was 72,460.10 HRK. The average total production costs in 2009 were 13,260.10 HRK, including the costs of fodder and veterinary services. All farms achieved positive financial results of 59,199.90 HRK in average. As many as three quarters of respondents indicated profitability of sheep production as the main motivation to engage in sheep production; very few indicated that heritage and inability to do other jobs were the main motivation. Important limiting factors for future development of sheep breeding on the island of Pag in most farms are lack of potential heirs and high average age of farm holders. Regarding the effects of joining the European Union, half the breeders intend to improve their production and harmonise it with the EU requirements and standards; one quarter of them intend to keep the existing production capacity; and another quarter intend to quit with production.

Biogas Production: Microbiology and Technology.

Science.gov (United States)

Schnürer, Anna

Biogas, containing energy-rich methane, is produced by microbial decomposition of organic material under anaerobic conditions. Under controlled conditions, this process can be used for the production of energy and a nutrient-rich residue suitable for use as a fertilising agent. The biogas can be used for production of heat, electricity or vehicle fuel. Different substrates can be used in the process and, depending on substrate character, various reactor technologies are available. The microbiological process leading to methane production is complex and involves many different types of microorganisms, often operating in close relationships because of the limited amount of energy available for growth. The microbial community structure is shaped by the incoming material, but also by operating parameters such as process temperature. Factors leading to an imbalance in the microbial community can result in process instability or even complete process failure. To ensure stable operation, different key parameters, such as levels of degradation intermediates and gas quality, are often monitored. Despite the fact that the anaerobic digestion process has long been used for industrial production of biogas, many questions need still to be resolved to achieve optimal management and gas yields and to exploit the great energy and nutrient potential available in waste material. This chapter discusses the different aspects that need to be taken into consideration to achieve optimal degradation and gas production, with particular focus on operation management and microbiology.

It has been over half a century since the successful separation of table isotopes carbon, nitrogen and oxygen. The production capacity achieved three levels improvements from the laboratory-scale of one hundred grams, to the pilot production of several kilo- grams, and mass production of one hundred kilograms. The separation technologies also achieved three generation progress. The first generation of separation technology was represented by thermal diffusion method, chromatography, and ion exchange; the second generation of separation technology was represented by chemical exchange, distillation; the third generation of separation technology was characterized by the techniques innovation of material recycling, energy coupling, energy saving, and large-scale production capacity. At present, "1"3C is wholly produced by cryogenic distillation method, "1"5N is produced by NO/HNO_3 chemical exchange and NO cryogenic distillation method, and "1"80 is manufactured by distillation of water, and cryogenic distillation of NO and O_2. The same features of these separation methods are achieving energy coupling, materials recycling, large-scale producing, and energy conservation in the process. In the future, it will be the theme of stable isotope industry to develop environment-friendly, raw materials available, energy saving, low-cost, and large-scale manufacturing technology through continuous technological innovation.

Full Text Available A study was conducted to analyze factors influencing adoption of wheat technology packages by smallholder farmers in Gurawa, Meta and Habro districts in eastern Ethiopia. The analysis was based on a household survey data collected from 136 randomly selected households. A Two-limit Tobit model was used to elucidate factors affecting adoption of technology packages measured based on an index derived from five components of wheat technologies which included row planting, pesticide application, use of improved varieties, and application of inorganic fertilizers, namely, Diammonium Phosphate (DAP and Urea. Among the variables included in the model, variation in district, gender, age of the household head, education status of the household head, farm size, distance to market, distance to FTC (Farmers’ Training Centers, cooperative membership, dependency ratio, and annual income of the households were found to significantly affect the adoption of wheat technology packages. Policy makers, planners and development practitioners should give due attention to these determinants to support smallholder farmers in wheat production and enhance gains derived from it.

The aim of this study was to compare health information technology (HIT) adoption strategies' relative performance on hospital-level productivity measures. The American Hospital Association's Annual Survey and Healthcare Information and Management Systems Society Analytics for fiscal years 2002 through 2007 were used for this study. A two-stage approach is employed. First, a Malmquist model is specified to calculate hospital-level productivity measures. A logistic regression model is then estimated to compare the three HIT adoption strategies' relative performance on the newly constructed productivity measures. The HIT vendor selection strategy impacts the amount of technological change required of an organization but does not appear to have either a positive or adverse impact on technical efficiency or total factor productivity. The higher levels in technological change experienced by hospitals using the best of breed and best of suite HIT vendor selection strategies may have a more direct impact on the organization early on in the process. However, these gains did not appear to translate into either increased technical efficiency or total factor productivity during the period studied. Over a longer period, one HIT vendor selection strategy may yet prove to be more effective at improving efficiency and productivity.

How to Improve the Supportive Role of Estonian Innovation System toward Launching New Products by High Technology Companies?

Directory of Open Access Journals (Sweden)

Liisi Sepp

2013-01-01

Full Text Available The purpose of the study is to evaluate how supportive is Estonian national innovation system toward the launching of new innovative products by high technology firms. The article intends to combine two broad areas of research – national innovation system approach and the different models of the new product launching. Based on the literature review and in-depth analysis of three case studies of Estonian high-tech company’s major barriers as well success factors of highly innovative product launches were identified. The barriers of the new product launching were linked with the systemic failures of the national innovation system. The most relevant failures of Estonian national innovation system inhibiting the new product development are capability and networking failures. The sources of innovation of high-technology firms are too narrow, linkages with domestic firms and higher education institutions as well with foreign firms are poorly developed. High-tech firms have also serious capacity problems due to the extremely weak support mechanism by national innovation system on the seed funding stage of product development and prototype building stage as well. Paper argues that resources needed for the innovation should not be looked too narrowly following linear innovation model approach. Instead interactive approach is needed, which combines capability building, network development, interactive learning with direct investments into fundamental research.

2010-01-01

This article provided a literature review of emerging technologies for ethanol production in Canada. A multi-criteria decision making (MCDM) panel was used to weigh critical metrics for evaluating the potential of emerging forest biorefinery technologies for bio-ethanol production. The 3-step methodology identified key factors for evaluating technology pathways. Key factors were applied to a group of selected technologies in order to collect data. All previous criteria were weighted through the MCDM panel in order to rank the technologies, which included biochemical pathway and thermochemical pathway production processes. Criteria included return on investment; feedstock flexibility; technology risk; energy and integration; products and revenue diversification; potential for additional products; and potential environmental impact. The study showed that techno-economic criteria are the most important barriers to the implementation of ethanol biorefineries. While thermochemical processes are economically feasible and provide greater flexibility, biochemical refining processes may provide for the development of other value-added products. 21 refs., 3 tabs., 7 figs.

Biodiesel production technologies: review

Directory of Open Access Journals (Sweden)

Shemelis Nigatu Gebremariam

2017-05-01

Full Text Available Biodiesel is a fuel with various benefits over the conventional diesel fuel. It is derived from renewable resources, it has less emission to environment, it is biodegradable so has very limited toxicity and above all its production can be decentralized so that it could have a potential in helping rural economies. However, there are also some worth mentioning challenges associated with production of biodiesel. Among them repeatedly mentioned are the cost of feedstock and the choice of convenient technology for efficient production of the fuel from diverse feedstock types. There are four main routes by which raw vegetable oil and/or animal fat can be made suitable for use as substituent fuel in diesel engines without modification. These are direct use or blending of oils, micro-emulsion, thermal cracking or pyrolysis and transesterification reaction. Due to the quality of the fuel produced, the transesterification method is the most preferred way to produce biodiesel from diverse feedstock types. Through this method, oils and fats (triglycerides are converted to their alkyl esters with reduced viscosity to near diesel fuel levels. There are different techniques to carry out transesterification reaction for biodiesel production. Each technique has its own advantages and disadvantages as well as its own specifically convenient feedstock character. There are also some very important reaction conditions to be given due attention in each of this techniques for efficient production of biodiesel, such as molar ratio of alcohol to oil, type and amount of catalyst, reaction temperature, reaction time, reaction medium, type and relative amount of solvents, among others. This review is meant to investigate the main transesterification techniques for biodiesel production in terms of their choice of feedstock character as well as their determinately required reaction conditions for efficient biodiesel production, so that to give an overview on their advantages

Technological Feasibility of Preserving Meat, Poultry and Fish Products by Using a Combination of Conventional Additives, Mild Heat Treatment and Irradiation

Energy Technology Data Exchange (ETDEWEB)

Wierbicki, E. [United States Army Natick Research and Development Laboratory, Natick, MD (United States)

1981-09-15

Radappertization, or irradiation sterilization of meats and other protein foods (poultry, seafoods) is a new processing method applicable to pre-cooked (enzyme inactivated) foods that are hermetically sealed (either in metal cans, flexible pouches, or metal or plastic trays) and involves irradiation to sterilizing doses of either gamma rays (from a cobalt-60 or caesium-137 source) or by X-rays and electrons. The process is particularly applicable to pre-cooked meat, poultry, fin fish, and shellfish, as well as to dry foods, animal feed, and spices. The resulting radappertized products are free from food spoilage microorganisms and organisms of public health significance, including the pathogens such as C. botulinum, salmonellae, trichinae, etc. The radappertized products can be stored without refrigeration for long periods (years), the limiting factor being the integrity of the primary packaging material. Irradiation sterilization of cured meats allows complete elimination or a drastic reduction of incoming nitrite to the levels needed only for characteristic colour and flavour of the items while providing protection against C. botulinum by irradiation. The irradiated-cured products with the low levels of added nitrite are free from residual nitrite and nitrosamines, including nitrosopyrrolidine in fried bacon. In recent co-operative research with the US Department of Agriculture, it was shown that irradiation also destroys pre-formed nitrosamines in bacon. The technology of the process was developed by the US National Food Irradiation Program and the US Army from 1953 to 1980. The US Army spearheaded the development of this new technology to the point where the food irradiation potentials have become meaningful within the broad scope of national and international interests. Therefore, it was highly appropriate that, effective 1 October 1980, the responsibility for the programme at this stage was transferred to the US Department of Agriculture which has been

Comparative Study of Laboratory-Scale and Prototypic Production-Scale Fuel Fabrication Processes and Product Characteristics

International Nuclear Information System (INIS)

2014-01-01

An objective of the High Temperature Gas Reactor fuel development and qualification program for the United States Department of Energy has been to qualify fuel fabricated in prototypic production-scale equipment. The quality and characteristics of the tristructural isotropic coatings on fuel kernels are influenced by the equipment scale and processing parameters. Some characteristics affecting product quality were suppressed while others have become more significant in the larger equipment. Changes to the composition and method of producing resinated graphite matrix material has eliminated the use of hazardous, flammable liquids and enabled it to be procured as a vendor-supplied feed stock. A new method of overcoating TRISO particles with the resinated graphite matrix eliminates the use of hazardous, flammable liquids, produces highly spherical particles with a narrow size distribution, and attains product yields in excess of 99%. Compact fabrication processes have been scaled-up and automated with relatively minor changes to compact quality to manual laboratory-scale processes. The impact on statistical variability of the processes and the products as equipment was scaled are discussed. The prototypic production-scale processes produce test fuels that meet fuel quality specifications.

2016-01-01

Full Text Available The effect of coal rank (from sub-bituminous to semi-anthracite and type of fuel feeding technology (slurry and dry on the production of substitute natural gas (SNG in entrained flow gasifiers is studied. Ten coals from important Colombian mines were selected. The process is modeled under thermochemical equilibrium using Aspen Plus, and its performance is evaluated in function of output parameters that include SNG heating value, Wobbe index, coal conversion efficiency, cold gas efficiency, process efficiency, global efficiency, and SNG production rate, among others. In descending order, the coal-to-SNG process improves energetically with the use of coals with: higher volatile-matter to fixed-carbon ratio, lower ash content, higher C+H/O ratio, and higher coal heating value. The overall energy efficiency of the slurry-feed technology (S-FT to produce SNG by gasification is 17% higher than the dry-feed technology (D-FT, possibly as a consequence of the higher CH4 concentration in the syngas (around 7 vol. % when the coal is fed as aqueous slurry. As the simulated SNG meets the natural gas (NG quality standards in Colombia, the substitute gaseous fuel could be directly transported through pipelines. Therefore, the coal-to-SNG process is a technically feasible and unconventional alternative for NG production.

Consumer concerns and expectations about novel food processing technologies: effects on product liking.

Science.gov (United States)

Cardello, Armand V

2003-06-01

Eighty-eight consumers participated in a blind pre-test in which they rated their baseline preference for chocolate pudding, their liking of three tasted brands of chocolate pudding, and their level of concern for 20 different food processing and preservation technologies. All returned one month later and tasted the same puddings, but this time they were informed that they had been processed by one of several different novel or traditional food processing techniques. Different sub-groups were informed of the name of the process, the name plus a factual description of the process, or the name, the factual description, plus a benefit statement. Ratings of expected liking were obtained before and after viewing the samples, but before tasting them. Finally, subjects tasted and rated the products for actual liking and a sub-group rated their concern levels for the same 20 technologies rated in the pre-test. Pre-test results showed females to have significantly higher concern levels for all technologies. Individuals who had demonstrated a willingness to consume foods processed by one novel technology (irradiation) had lower concern ratings for all technologies. Ratings of concern were negatively correlated with expected liking for products believed to be processed by the technologies. Expected liking ratings were positively influenced by visual exposure to the product and by a safety and benefit statement. Linear regression of the change in product liking as a function of whether products were better or worse than expected supported an assimilation model of the effect of disconfirmed expectations on liking/disliking. Lastly, post-test concern levels for many of the technologies were reduced by participation in the study.

Projection display technology and product trends

Major technology and market trends that could generate a 20 billion dollar electronic projector market by 2010 are reviewed in the perspective of recent product introductions. A log linear analysis shows that the light outputs of benchmark transportable data video projectors have increased at a rate of almost 90 percent per year since 1993. The list prices of these same projectors have decreased at a rate of over 40 percent per year. The tradeoffs of light output vs. resolution and weight are illustrated. Recent trends in projector efficacy vs. year are discussed. Lumen output per dollar of list price is shown to be a useful market metric. Continued technical advances and innovations including higher throughput light valve technologies with integrated drivers, brighter light source, field sequential color, integrated- and micro-optical components, and aerospace materials are likely to sustain these trends.

Full Text Available The aim of the present paper is to make a review of the modern trends in the development of the technologies for production of dental constructions. Three are the main trends in production technologies in dentistry last 30 years: digitalization, simulation and implementation of additive technologies. The simulation occurred first and due to the computers development it underwent fast progress from the mathematical calculations and analytical analysis to the 3D modeling and visualization. Thus Computer Aided Engineering (CAE was developed, allowing dental constructions with optimal design to be produced by optimal technological regimes. The first Computer Aided Design (CAD – Computer Aided Manufacturing (CAM systems were created in 1970s as a result of the digitalization. In this mode of operation at first virtual 3D model is generated by CAD, which then is used for production of the real construction by CAM. The CAD-CAM systems allow fabrication of dental restorations which is difficult or impossible to be manufactured by conventional technologies. The development of CAD unit runs from indirect scanning of the plaster model for obtaining data for the 3D model to direct scanning of the prosthesis area. While the development of CAM unit leads to direct manufacturing of the real dental construction using subtractive or additive technologies. The future development of the CAD-CAM systems as a whole characterizes with transition from closed to open access systems, which make them more flexible. In the late 1980sthe new approach to the production of constructions appeared – by addition of material layer by layer. The additive technologies were developed. They characterize with building of one layer at a time from a powder or liquid that is bonded by means of melting, fusing or polymerization. Stereo lithography, fused deposition modeling, selective electron beam melting, laser powder forming and inkjet printing are the methods, mostly used in

Full Text Available Unconventional methods of modern materials preparation include additive technologies which involve the sintering of powders of different chemical composition, granularity, physical, chemical and other utility properties. The technology called Rapid Prototyping, which uses different technological principles of producing components, belongs to this type of material preparation. The Rapid Prototyping technology facilities use photopolymers, thermoplastics, specially treated paper or metal powders. The advantage is the direct production of metal parts from input data and the fact that there is no need for the production of special tools (moulds, press tools, etc.. Unused powder from sintering technologies is re-used for production 98% of the time, which means that the process is economical, as well as ecological.The present paper discusses the technology of Direct Metal Laser Sintering (DMLS, which falls into the group of additive technologies of Rapid Prototyping (RP. The major objective is a detailed description of DMLS, pointing out the benefits it offers and its application in practice. The practical part describes the production and provides an economic comparison of several prototype parts that were designed for testing in the automotive industry.

Technology benefits resulting from accelerator production of tritium

International Nuclear Information System (INIS)

1998-01-01

One of the early and most dramatic uses of nuclear transformations was in development of the nuclear weapons that brought World War II to an end. Despite that difficult introduction, nuclear weapons technology has been used largely as a deterrent to war throughout the latter half of the twentieth century. The Accelerator Production of Tritium (APT) offers a clean, safe, and reliable means of producing the tritium (a heavy form of hydrogen) needed to maintain the nuclear deterrent. Tritium decays away naturally at a rate of about 5.5% per year; therefore, the tritium reservoirs in nuclear weapons must be periodically replenished. In recent years this has been accomplished by recycling tritium from weapons being retired from the stockpile. Although this strategy has served well since the last US tritium production reactor was shut down in 1988, a new tritium production capability will be required within ten years. Some benefits will result from direct utilization of some of the APT proton beam; others could result from advances in the technologies of particle accelerators and high power spallation targets. The APT may save thousands of lives through the production of medical isotopes, and it may contribute to solving the nation's problem in disposing of long-lived nuclear wastes. But the most significant benefit may come from advancing the technology, so that the great potential of accelerator applications can be realized during our lifetimes

2002-11-01

The report describes and evaluates a selection of technologies which may be adequate for a local power production at the end consumer. Contrary to may other technology surveys it is focused on small-scale production units that also may be of interest to small consumers. For the various technologies the particular technology is described and an evaluation of the suitability to Norwegian conditions is carried out. For each technology the following is described: 1) The technology in general. 2) Construction and technology trends. 3) Environmental conditions, operation and maintenance. 4) Experiences. 5) Key facts/data. It has to be emphasised that all the technologies are in development and this report describes them as they are in 2002 except for general conditions which always will exist. It has not been possible to obtain exact facts regarding the investment costs and the costs for each produced kWh e lectricity or kWh h eat for many of the technologies because they are new and mass production has not yet started. In an appendix a form is presented for use in obtaining information from equipment suppliers. Later in the project there will be developed a model for calculating the profitability of such investments as well. Technologies such as small-scale wind and hydropower units are the technologies most suited for Norway in a short perspective. In the years to come it is probable that technologies which use biologic fuel/waste of some kind would be used to some extent. In a longer perspective technologies as the Stirling engine and fuel cells may be of interest. The micro gas turbines and combustion engines may be current technologies if the distribution network for natural gas is developed. For these technologies the utilisation of waste heat would approximately double the efficiency and halve the operation costs. Various external conditions will play a major part in the spreading of the local power production. The political, legal and economical external

Full Text Available This study aims at exploring how an integrated product and service contributes to achieving Innovation of Meaning (IoM or technology epiphany. Existing IoM studies have focused on intended meaning (as defined in new product development and ignored the received meaning that users reconstruct. The process by which a user assigns meaning to things can not only be static but also dynamic. This study focuses on integrated products and contexts offered by services and analyses the case of Japan’s largest manufacturer of ankle-foot orthoses. The results show that the service guides the users to reconstruct the meaning in dynamic cognitive processes and use the metaphors that contribute to the consistency between products and services.

Technology and economic assessment of lactic acid production and uses

Energy Technology Data Exchange (ETDEWEB)

Datta, R.; Tsai, S.P.

1996-03-01

Lactic acid has been an intermediate-volume specialty chemical (world production {approximately}50,000 tons/yr) used in a wide range of food-processing and industrial applications. Potentially, it can become a very large-volume, commodity-chemical intermediate produced from carbohydrates for feedstocks of biodegradable polymers, oxygenated chemicals, environmentally friendly ``green`` solvents, and other intermediates. In the past, efficient and economical technologies for the recovery and purification of lactic acid from fermentation broths and its conversion to the chemical or polymer intermediates had been the key technology impediments and main process cost centers. Development and deployment of novel separations technologies, such as electrodialysis with bipolar membranes, extractive and catalytic distillations, and chemical conversion, can enable low-cost production with continuous processes in large-scale operations. The emerging technologies can use environmentally sound lactic acid processes to produce environmentally useful products, with attractive process economics. These technology advances and recent product and process commercialization strategies are reviewed and assessed.

Production technologies for molybdenum-99 and technetium-99m

International Nuclear Information System (INIS)

1999-02-01

Technetium-99m (6.02 h) is the most widely used radioisotope in nuclear medicine, accounting for more than 80% of all diagnostic nuclear medicine procedures. It is almost exclusively produced from the decay of its parent 99 Mo. The present sources of 99 Mo are research reactors by using the (n,γ) nuclear reaction with natural Mo ( 98 Mo, ∼24%), resulting in inexpensive but low-specific activity 99 Mo, or by neutron-induced fission of 235 U, which results in expensive but high specific activity 99 Mo. This publication covers several aspects related to the production of 99 Mo and 99m Tc. The contributed papers reflect the current status of the technology and discuss potential alternative methodologies for the production of 99 Mo and 99m Tc for medical use. The first four papers address the technologies using nuclear reactors, including the description of a new method using an aqueous homogenous reactor core for production of fission 99 Mo and the latest development efforts to fabricate 235 U low enriched targets (LEU, 235 U). The next five papers discuss the potential of utilizing particle accelerators and assess the current status of the available nuclear data for the production of both, 99 Mo and 99m Tc with proton and deuteron beams. The last paper discusses a new technology based on gel system for the preparation of 99 Mo/ 99m Tc generators using low specific activity 99 Mo produced in research reactors by the neutron activation of natural and inexpensive molybdenum oxide targets.

Assessing production characteristics, influential factors and administrative policies in a multicenter dental organization.

Science.gov (United States)

Patterson, Charles W

2012-06-01

In multicenter service organizations, managers often make centralized decisions without considering the effects of differing production characteristics and influential factors on each center. In this study, the author examines differences in production characteristics and factors that influence production, as well as their likely effect on policy formulation, in a large, six-center dental group in the Chicago area. The results of the study show that the six centers (in two groups) exhibited two distinct production patterns, with three having logarithmic distributions and three having normal distributions. Production differences between the groups likely resulted from differences in managed care, staffing and dental procedures performed. Instead of being monolithic, the organization exhibited two types of centers, each with its own production characteristics and factors that influenced production. The study results suggest that large service corporations and }partnerships would benefit from conducting analyses of production characteristics and factors that influence production before making policy decisions that affect the entire organization.

2017-07-01

To reduce fermentation-associated wastewater discharge and the cost of wastewater treatment, which further reduces the total cost of DHA and ARA production, this study first analyzed the composition of wastewater from Aurantiochytrium (DHA) and Mortierella alpina (ARA) fermentation, after which wastewater recycling technology for these fermentation processes was developed. No negative effects of DHA and ARA production were observed when the two fermentation wastewater methods were cross-recycled. DHA and ARA yields were significantly inhibited when the wastewater from the fermentation process was directly reused. In 5-L fed-batch fermentation experiments, using this cross-recycle technology, the DHA and ARA yields were 30.4 and 5.13gL -1 , respectively, with no significant changes (P>0.05) compared to the control group, and the water consumption was reduced by half compared to the traditional process. Therefore, this technology has great potential in industrial fermentation for polyunsaturated fatty acid production. Copyright © 2017 Elsevier Ltd. All rights reserved.

2013-01-01

The study examined the impact of improved technologies on the lives of small-scale soybean farmers in Benue State, Nigeria. A total of 160 respondents were selected using simple random sampling technique. Data were analyzed using descriptive statistics, Tobit model and the Kruskal-Wallis test. Findings revealed that 35.6% of the respondents were between 31 and 40 years old, 40.6% had household size of between 6 and 10 members. Majority of the respondents were male, married, and had secondary school education. Tobit analysis revealed that farmers socioeconomic characteristics which include gender, educational status and farming experience; and farmers knowledge on soybean innovations were significant factors determining the adoption of improved soybean production technologies. These factors were statistically significant at p=0.05. The adoption of improved soybean technologies has had a clear positive impact on farmers belief on soybean innovations. The major problems facing farmers in the adoption of improved soybean production technologies according to Kruskal-Wallis ranking were high cost of inputs, problem of labour availability and lack of credit/loan. The results of this study provide a strong case for the promotion of soybean as a solution for malnutrition and a means of poverty alleviation for poor people. (author)

Impacts of reproductive technologies on beef production in the United States.

Dahlen, Carl; Larson, Jamie; Lamb, G Cliff

2014-01-01

Estimations of world population growth indicate that by the year 2050 we will reach nine billion habitants on earth. These estimates impose a tremendous challenge in the current agricultural systems as food supply will need to increase by 100 % in the next 40 years (Food and Agriculture Organization of the United Nations 2009). Beef will be a primary protein source that will assist in meeting the requirements for a portion of the protein in diets of this expanding global populace. Beef is a high-quality protein that contains all essential amino acids for the human body and also contains additional essential nutrients such as iron, zinc, B vitamins, riboflavin, selenium, choline, and conjugated linoleic acid (CLA). Adopting reproductive technologies at greater rates than currently used is a viable method to dramatically enhance production efficiency of beef cattle enterprises.Artificial insemination (AI), estrous synchronization and fixed-time AI (TAI), semen and embryo cryopreservation, multiple ovulation and embryo transfer (MOET), in vitro fertilization, sex determination of sperm or embryos, and nuclear transfer are technologies that are used to enhance the production efficiency of beef operations. In many cases, the development of these technologies is responsible for significant changes to traditional livestock production practices. However, adoption of these technologies appears to has not grown at the same rate in the United States as other formidable beef producing nations. For example, sales of beef semen for AI increased from 3.3 to 11.9 million units between 1993 and 2011 in Brazil, whereas that in the United States has increased from 2.9 to 3.8 million units during the same period. The significant increases in adoption of reproductive technologies in developing countries is likely as a result of the development of practical estrous synchronization and TAI systems that have allowed beef producers the opportunity to eliminate detection of estrus in their

1999-01-01

The electron beam (EB) curing technology has rapidly advanced in recent years. However there were few examples applying this technology to paper products. One reason comes from the high price of EB equipment and the other comes from the difficulty of controlling the irradiation which gives damages to paper. In spite of these problems, the EB cured coating layer shows remarkable features, such as solvent-resistance, water-resistance, heat-resistance and high smoothness using the drum casting technique. Concentrating on application of this technology to paper, we have already developed some products. For example, paper for printings (Super Mirror PN) and for white boards (Super Mirror WB) have been manufactured. In this presentation, we are going to introduce this EB curing technique and the products

Wilhelm, D.J.; Simbeck, D.R.; Karp, A.D.; Dickenson, R.L. [SFA Pacific, Inc., 444 Castro St., Suite 720, 94041 Mountain View, CA (United States)

2001-06-01

The main gas-to-liquids (GTL) interest now is in Fischer-Tropsch (F-T) synthesis of hydrocarbons. While synthesis gas (syngas) for GTL can be produced from any carbon-based feedstock (hydrocarbons, coal, petroleum coke, biomass), the lowest cost routes to syngas so far are based on natural gas. Thus, the focus for GTL has been largely on associated gas, so-called stranded or remotely located gas reserves, and larger gas reserves that are not currently being economically exploited. The principal technologies for producing syngas from natural gas are: catalytic steam methane reforming (SMR), two-step reforming, autothermal reforming (ATR), partial oxidation (POX), and heat exchange reforming. The distinguishing characteristics of these technologies and their commercial uses are discussed in this paper. Ongoing R and D efforts to develop lower-cost syngas generation technologies are also briefly discussed.Relevant commercial experience with large-scale syngas generation for GTL is also discussed. As a frame of reference, in terms of syngas flow rates, a 20,000 b/day F-T plant would be comparable to three 2500 mt/day methanol plants. Single-train methanol plants are now producing more than 2500 t/day-and plants approaching 3000 mt/day have been announced. The projected relative economies of scale of the various syngas production technologies indicate that two-step reforming and ultimately, ATR, should be the technologies of choice for large-scale GTL plants. Nevertheless, for a 20,000 b/day F-T liquids plant, capital charges still dominate the manufacturing costs. Syngas production (oxygen plant and reforming) comprises half of the total capital cost of this size GTL plant. While air-blown reforming eliminates the expensive oxygen plant, air-blown reforming is unlikely to be competitive with, or offer the flexibility of, oxygen-blown reforming. The reasons for this conclusion are discussed.The proposed and future GTL facilities should be substantially less costly than

The main gas-to-liquids (GTL) interest now is in Fischer-Tropsch (F-T) synthesis of hydrocarbons.

Leinonen, A.

2007-12-15

This work has been done in the project where the main target is to evaluate the technology and economy to use bush biomass for power production in Namibia. The project has been financed by the Ministry for Foreign Affairs of Finland and the Ministry of Agriculture, Water and Forestry of the Republic of Namibia. The target of this study is to calculate the production costs of bush chips at the power plant using the current production technology and to look possibilities to develop production technology in order to mechanize production technology and to decrease the production costs. The wood production costs are used in feasibility studies, in which the technology and economy of utilization of wood chips for power generation in 5, 10 and 20 MW electric power plants and for power generation in Van Eck coal fired power plant in Windhoek are evaluated. Field tests were made at Cheetah Conservation Farm (CCF) in Otjiwarongo region. CCF is producing wood chips for briquette factory in Otjiwarongo. In the field tests it has been gathered information about this CCF semi-mechanized wood chip production technology. Also new machines for bush biomass chip production have been tested. A new mechanized production chain has been designed on the basis of this information. The production costs for the CCF semi-mechanized and the new production chain have been calculated. The target in the moisture content to produce wood chips for energy is 20 w-%. In the semi-mechanized wood chip production chain the work is done partly manually, and the supply chain is organized into crews of 4.8 men. The production chain consists of manual felling and compiling, drying, chipping with mobile chipper and manual feeding and road transport by a tractor with two trailers. The CCF production chain works well. The chipping and road transport productivity in the semimechanized production chain is low. New production machines, such as chainsaw, brush cutter, lawn mover type cutter, rotator saw in skid

The automation technology of magnetic pulsed compaction (MPC) has been developed for mass production of high performance powder products by dynamic compaction method. The pulse power equipment in MPC system has been modified for improved lifetime and productivity, so the modified one can produce high-density compacts at a rate of 10 times/min with semipermanent lifetime. Using this modified pulse power equipment, two types of automated MPC apparatus were constructed, which are operated by mechanical and hydraulic driving systems, respectively. By repeated compaction operations at a rate of 5 times/min, durability and productivity of these automated apparatus have been proven to be suitable for mass production. In addition, the lifetime of mold and punch for MPC has been improved by optimizing design and material as well as employing new lubrication system. By applying such automated MPC apparatus, detailed mass production technologies have been developed for several powder products such as diamond drilling segments, ceramic targets for optical coating, silver coins for water disinfection and small powder products for automobile. The developed powder products showed improved performance as compared to commercial ones, so they will be mass-produced industrially before long

Full Text Available The electrochemical alane production process was proposed for a feasible production of alane. The operation of process was difficult because of short circuit by a dendrite growth in the reactor. Therefore, characteristics of the dendrite growth in the process were investigated. We conducted the electrochemical alane production process using Teflon block for inhibition of the dendrite growth. The obtained dendrite was characterized by XRD, SEM and ICP-AES. It was concluded that the dendrite growth was attributed to a melting and agglomeration of Al fine particles existed in the solution.

Innovative applications of technology for nuclear power plant productivity improvements

Naser, J. A.

2012-01-01

The nuclear power industry in several countries is concerned about the ability to maintain high plant performance levels due to aging and obsolescence, knowledge drain, fewer plant staff, and new requirements and commitments. Current plant operations are labor-intensive due to the vast number of operational and support activities required by commonly used technology in most plants. These concerns increase as plants extend their operating life. In addition, there is the goal to further improve performance while reducing human errors and increasingly focus on reducing operations and maintenance costs. New plants are expected to perform more productively than current plants. In order to achieve and increase high productivity, it is necessary to look at innovative applications of modern technologies and new concepts of operation. The Electric Power Research Inst. is exploring and demonstrating modern technologies that enable cost-effectively maintaining current performance levels and shifts to even higher performance levels, as well as provide tools for high performance in new plants. Several modern technologies being explored can provide multiple benefits for a wide range of applications. Examples of these technologies include simulation, visualization, automation, human cognitive engineering, and information and communications technologies. Some applications using modern technologies are described. (authors)

Redd, Evan M.; Sjoden, Glenn; Erickson, Anna

2017-01-01

Highlights: •X-10 reactor is used as a case study for nuclear forensic signatures. •S/U analysis is conducted to derive statistically relevant markers. •Computationally-generated signatures aid with proliferation pathway identification. •Highest uncertainty in total plutonium production originates from 238 Pu and 242 Pu. -- Abstract: With nuclear technology and analysis advancements, site access restrictions, and ban on nuclear testing, computationally-generated nuclear forensic signatures are becoming more important in gaining knowledge to a reclusive country’s weapon material production capabilities. In particular, graphite-moderated reactors provide an appropriate case study for isotopics relevant in Pu production in a clandestine nuclear program due to the ease of design and low thermal output. We study the production characteristics of the X-10 reactor with a goal to develop statistically-relevant nuclear forensic signatures from early Pu production. In X-10 reactor, a flat flux gradient and low burnup produce exceptionally pure Pu as evident by the 240 Pu/ 239 Pu ratio. However, these design aspects also make determining reactor zone attribution, done with the 242 Pu/ 240 Pu ratio, uncertain. Alternatively, the same ratios produce statistically differentiable results between Manhattan Project and post-Manhattan Project reactor configurations, allowing for attribution conclusions.

Application of Modern Technologies for Nuclear Power Plant Productivity Improvements

Joseph, A. Naser

2011-01-01

The nuclear power industry in several countries is concerned about the ability to maintain current high plant performance levels due to aging and obsolescence, knowledge drain, fewer plant staff, new requirements and commitments, unnecessary workloads and stress levels, and human errors. Current plant operations are labor-intensive due to the vast number of operational and support activities required by the commonly used technology in most plants. These concerns increase as plants extend their operating life. In addition, there is the desire by many plants to further improve performance while reducing human errors and increasingly focus on reducing operations and maintenance costs. New productivity improvement capabilities with measurable economic benefits are needed so that a successful business case can be made for their use. Improved and new instrumentation and control, human-system interface, information and communications technologies used properly can address concerns about cost-effectively maintaining current performance levels and enable shifts to even higher performance levels. This can be accomplished through the use of new technology implementations to improve productivity, reduce costs of systemic inefficiencies and avoid unexpected costs. Many of the same type of productivity improvements for operating plants will be applicable for new plants. As new plants are being built, it is important to include these productivity improvements or at least provide the ability to implement them easily later

A technical selection of suitable agricultural products for the application of radurisation technology

International Nuclear Information System (INIS)

Hill, N.D.

1989-01-01

The commercial utilization of radurization technology has not reached the levels expected due, predominantly, to two contributing factors. Over and above the suspicions held by the consumer towards food radurization, a dearth of information exists regarding the costs of applying this technology. It appears, therefore, that if the question of consumer acceptance is surmounted, an indication of benefit costs would be crucial to convincing potential radurization users whether or not this technology can provide any economic benefit. The range of food and agricultural products consumed in South Africa is very diverse. To determine the radurization benefit cost of each food product consumed in South Africa would, therefore, be a monumental task. As a result an investigation was commissioned by the Study Group for the Techno-Economic Aspects of the Steering Committee for the Marketing of Radurized Food Products. This investigation was aimed, in the first instance, at identifying those food and agricultural products best suited for the application of this technology, thereby creating a short list on which detailed benefit cost analyses could be performed

1976-01-01

Some aspects of the use of heat of nuclear origin for the production of hydrogen by water-splitting are considered. General notions pertaining to the yield of chemical cycles are discussed and the heat balance corresponding to two specific processes is evaluated. The possibilities of high temperature reactors, with respect to the coolant temperature levels, are examined from the standpoint of core design and technology of some components. Furthermore, subject to a judicious selection of their characteristics, these reactors can lead to excellent use of nuclear fuel. The coupling of the nuclear reactor with the chemical plant by means of a secondary helium circuit gives rise to the design of an intermediate heat exchanger, which is an important component of the overall installation.

Full Text Available The use of New Rice for Africa (NERICA and complementary rice production technology is being promoted by Nigeria government in order to increase productivity of upland rice farming. This study examines the levels, determinants and effects of complementary technology adoption on productivity of NERICA rice farming. Data for the study were obtained from sample survey of 227 NERICA rice farmers in the guinea savanna zone using multistage sampling technique. Data collected were analyzed using Tobit regression model and Cobb-Douglas production function. Results showed that the average technology score was 52.1 percent (+ 0.242. Fifty-five percent of the farmers who scored above the mean were categorized as low technology users. Tobit regression estimation shows that farmers' technology score was affected significantly (P< 0.05 by farmer's level of education (0.0127, extension visit (0.0145, farming experience (0.0085, land ownership status (0.0687, credit use (0.0698 and level of rice commercialization (0.3783. Cobb-Douglas production estimation shows a neutrally outward shift in production function as the level of complementary technology increases, indicating increasing productivity. Thus, promotion of complementary technology in NERICA rice production is a worthwhile effort and should continue to be funded. Improvement of those factors that significantly affect adoption of complementary technology is recommended.

2015-01-01

Full Text Available In the alcohol industry it is important to create non-waste technology for grain processing into alcohol. The aim of research was the development of technology for wheat processing into ethanol and protein product. We studied the process of enzymatic hydrolysis of starch with glucoamylase of Glucogam preparation. We determined the optimal dosage of the enzyme 8 units. GlA/g of starch, and the temperature of 55°C. In the study of protein hydrolysis by the concomitant to glucoamylase protease of enzyme Glucogam preparation accumulation of amino nitrogen of 4.5 mg / cm 3 in 7 hours of bioconversion takes place. Separation of the resulting saccharified mass was carried out by centrifugation into the filtrate and protein mass. Centrifugation was carried out at a rotational speed of 2500 rev / min for 8 minutes. Protein was dried to 5% moisture content at temperatures not exceeding 35°C, milled, and examined its properties in comparison with native wheat gluten. The resulting product had the following characteristics: the solubility of 10%, water-holding capacity of 1.53 g / g, and fat binding capacity of 1.9 g /g. We investigated the process of fermentation of clarified wort with the dry solids concentration of 14%. We used the yeast Saccharomyces cerevisiae of race XII and Saccharomyces cerevisiae of race IMB Y-5007 in the dose of 120 million cells per 1 cm3 of wort. Optimum composition of mineral salts was determined. For the yeasts of race XII and IMB Y-5007 fertilizing with diammonium phosphate in a dosage of 1.5 g / dm3 is necessary. The alcohol yield when using the yeasts of race IMB Y-5007 was 60.7 dal/ ton of conditional starch, when using yeasts of race XII it accounts 60,6 dal / ton of conditional starch.

Microalgal biomass as renewable energy source is believed to be of great potential for reliable and sustainable biofuels production. However, microalgal biomass production is pinned by harvesting and dewatering stage thus hindering the developing and growing microalgae biotechnology industries. Flotation technology applied in mineral industry could be potentially applied in microalgae harvesting and dewatering, however substantial knowledge on different flotation units is essential. This paper presents an overview on different flotation units as promising cost-effective technologies for microalgae harvesting thus bestowing for further research in development and commercialization of microalgae based biofuels. Dispersed air flotation was found to be less energy consuming. Moreover, Jameson cell flotation and dispersed ozone flotation are believed to be energy efficient microalgae flotation approaches. Microalgae harvesting and dewatering by flotation is still at embryonic stage, therefore extended studies with the focus on life cycle assessment, sustainability of the flotation unit, optimization of the operating parameters using different algal species is imperative. Though there are a number of challenges in microalgae harvesting and dewatering, with well designed and developed cultivation, harvesting/dewatering, extraction and conversion technologies, progressively, microalgae technology will be of great potential for biological carbon sequestration, biofuels and biochemicals production.

Wagner, K.

1986-01-01

Products of technical carbon are made of cokes of different origin, ash content and grain size and of different binders (pitch, tar). For the full understanding of the technical carbon production process analyses are necessary. Investigations were performed by aid of the radioindicator method. One coke component was labelled by 140 La. From the specific radioactivity of samples of a 36 ton mixed coke charge it could be shown that some of the technological steps, i.e. mixing at the coke storage place, calcination, milling, sieving, and mixing with the binder give good mixing effects. Continuous radioactivity measurements (on stream) of the coke mixture showed different streaming velocities of the coke through the furnaces and the furnace chambers, i.e. charges of different composition following each other are mixed together over some hours.

2004-01-01

By analogy with the concepts of human learning, we show and introduce a new method to obtain least product cost and price that includes the effect of innovation and technological learning in manufacturing and production. This key result is a new paradigm instead of the usual economic 'power law' formulation. The new analysis is based on extensive analysis of many technological systems, and is directly related to the presence of learning as experience is accumulated. The results agree with the observed data. By using a consistent basis, the method replaces previous empirical 'power law' descriptions of the technological learning curve with a new 'marginal minimum cost equation' (MCE). (author)

IMPROVING THE EFFECTIVENESS AND EFFICIENCY OF EVIDENCE PRODUCTION FOR HEALTH TECHNOLOGY ASSESSMENT.

Science.gov (United States)

Facey, Karen; Henshall, Chris; Sampietro-Colom, Laura; Thomas, Sarah

2015-01-01

Health Technology Assessment (HTA) needs to address the challenges posed by high cost, effective technologies, expedited regulatory approaches, and the opportunities provided by collaborative real-world evaluation of technologies. The Health Technology Assessment International (HTAi) Policy Forum met to consider these issues and the implications for evidence production to inform HTA. This paper shares their discussion to stimulate further debate. A background paper, presentations, group discussions, and stakeholder role play at the 2015 HTAi Policy Forum meeting informed this paper. HTA has an important role to play in helping improve evidence production and ensuring that the health service is ready to adopt effective technologies. It needs to move from simply informing health system decisions to also working actively to align stakeholder expectations about realistic evidence requirements. Processes to support dialogue over the health technology life cycle need to be developed that are mindful of limited resources, operate across jurisdictions and learn from past processes. Collaborations between health technology developers and health systems in different countries should be encouraged to develop evidence that will inform decision making. New analytical techniques emerging for real-world data should be harnessed to support modeling for HTA. A paradigm shift (to "Health Innovation System 2.0") is suggested where HTA adopts a more central, proactive role to support alignment within and amongst stakeholders over the whole life cycle of the technology. This could help ensure that evidence production is better aligned with patient and health system needs and so is more effective and efficient.

The Department of Energy, Office of Nuclear Energy, has requested that a Hydrogen Technology Down-Selection be performed to identify the hydrogen production technology that has the best potential for timely commercial demonstration and for ultimate deployment with the Next Generation Nuclear Plant (NGNP). An Independent Review Team has been assembled to execute the down-selection. This report has been prepared to provide the members of the Independent Review Team with detailed background information on the High Temperature Electrolysis (HTE) process, hardware, and state of the art. The Idaho National Laboratory has been serving as the lead lab for HTE research and development under the Nuclear Hydrogen Initiative. The INL HTE program has included small-scale experiments, detailed computational modeling, system modeling, and technology demonstration. Aspects of all of these activities are included in this report. In terms of technology demonstration, the INL successfully completed a 1000-hour test of the HTE Integrated Laboratory Scale (ILS) technology demonstration experiment during the fall of 2008. The HTE ILS achieved a hydrogen production rate in excess of 5.7 Nm3/hr, with a power consumption of 18 kW. This hydrogen production rate is far larger than has been demonstrated by any of the thermochemical or hybrid processes to date.

A mapping exercise was undertaken to determine how HTA is being described and conducted across the International Network of Agencies for Health Technology Assessment (INAHTA), with the aim of harmonizing terminologies and approaches. Three progressive surveys were undertaken. In 2010, INAHTA agencies were asked to provide details on all of their HTA products. In 2013, additional information was sought on key methodological characteristics of five of the most common HTA product types. Subsequently, final agreement was sought on three proposed product types. Forty-five HTA agencies responded to at least one of the surveys. In 2010, twenty-one agencies reported publishing over seventy named HTA products. Core domains associated with full HTA reports were reported by a third of agencies but were labeled differently, so products were classified according to product type (n = 17). Agencies producing short, tailored products increased between 2010 and 2013, with the publication of rapid reviews doubling from 33 percent to 66 percent. In 2013, half of the agencies adapted their common HTA products from documents produced by other agencies. A consensus (>70 percent) was achieved on definitions for HTA reports, mini-HTAs, and rapid reviews. The product label for an HTA is not always indicative of its content. Terminology has, therefore, been agreed to make explicit the trade-off between rigor and timeliness in three common HTA product types. An INAHTA Product Type (IPT) Mark has been created to identify each of these. It is hoped this will further facilitate HTA adaptation between agencies and reduce duplication of effort.

Lactobacillus delbrueckii ssp. bulgaricus (L. bulgaricus) is well known for its worldwide application in yogurt production. Flavor production and acid producing are considered as the most important characteristics for starter culture screening. To our knowledge this is the first study applying functional gene sequence multilocus sequence typing technology to predict the fermentation and flavor-producing characteristics of yogurt-producing bacteria. In the present study, phenotypic characteristics of 35 L. bulgaricus strains were quantified during the fermentation of milk to yogurt and during its subsequent storage; these included fermentation time, acidification rate, pH, titratable acidity, and flavor characteristics (acetaldehyde concentration). Furthermore, multilocus sequence typing analysis of 7 functional genes associated with fermentation time, acid production, and flavor formation was done to elucidate the phylogeny and genetic evolution of the same L. bulgaricus isolates. The results showed that strains significantly differed in fermentation time, acidification rate, and acetaldehyde production. Combining functional gene sequence analysis with phenotypic characteristics demonstrated that groups of strains established using genotype data were consistent with groups identified based on their phenotypic traits. This study has established an efficient and rapid molecular genotyping method to identify strains with good fermentation traits; this has the potential to replace time-consuming conventional methods based on direct measurement of phenotypic traits.

Reliability modeling of degradation of products with multiple performance characteristics based on gamma processes

International Nuclear Information System (INIS)

Pan Zhengqiang; Balakrishnan, Narayanaswamy

2011-01-01

Many highly reliable products usually have complex structure, with their reliability being evaluated by two or more performance characteristics. In certain physical situations, the degradation of these performance characteristics would be always positive and strictly increasing. In such a case, the gamma process is usually considered as a degradation process due to its independent and non-negative increments properties. In this paper, we suppose that a product has two dependent performance characteristics and that their degradation can be modeled by gamma processes. For such a bivariate degradation involving two performance characteristics, we propose to use a bivariate Birnbaum-Saunders distribution and its marginal distributions to approximate the reliability function. Inferential method for the corresponding model parameters is then developed. Finally, for an illustration of the proposed model and method, a numerical example about fatigue cracks is discussed and some computational results are presented.

Zheng, Kai; Zou, Xingli; Xie, Xueliang; Lu, Changyuan; Chen, Chaoyi; Xu, Qian; Lu, Xionggang

2018-02-01

This paper investigated the electrolytic production of Ti5Si3/TiC composites from TiO2/SiO2/C in molten CaCl2. The solid-oxide oxygen-ion-conducting membrane tube filled with carbon-saturated liquid tin was served as the anode, and the pressed spherical TiO2/SiO2/C pellet was used as the cathode. The electrochemical reduction process was carried out at 1273 K and 3.8 V. The characteristics of the obtained cathode products and the reaction mechanism of the electroreduction process were studied by a series of time-dependent electroreduction experiments. It was found that the electroreduction process generally proceeds through the following steps: TiO2/SiO2/C → Ti2O3, CaTiO3, Ca2SiO4, SiC → Ti5Si3, TiC. The morphology observation and the elemental distribution analysis indicate that the reaction routes for Ti5Si3 and TiC products are independent during the electroreduction process.

Developing technology for large-scale production of forest chips. Wood Energy Technology Programme 1999-2003. Interim report

International Nuclear Information System (INIS)

Hakkila, P.

2003-01-01

Finland is enhancing its use of renewable sources in energy production. From the 1995 level, the use of renewable energy is to be increased by 50 % by 2010, and 100 % by 2025. Wood-based fuels will play a leading role in this development. The main source of wood-based fuels is processing residues from the forest industries. However, as all processing residues are already in use, an increase is possible only as far as the capacity and wood consumption of the forest industries grow. Energy policy affects the production and availability of processing residues only indirectly. Another large source of wood-based energy is forest fuels, consisting of traditional firewood and chips comminuted from low-quality biomass. It is estimated that the reserve of technically harvest-able forest biomass is 10-16 Mm' annually, when no specific cost limit is applied. This corresponds to 2-3 Mtoe or 6-9 % of the present consumption of primary energy in Finland. How much of this re-serve it will actually be possible to harvest and utilize depends on the cost competitiveness of forest chips against alternative sources of energy. A goal of Finnish energy and climate strategies is to use 5 Mm' forest chips annually by 2010. The use of wood fuels is being promoted by means of taxation, investment aid and support for chip production from young forests. Furthermore, research and development is being supported in order to create techno-economic conditions for the competitive production of forest chips. In 1999, the National Technology Agency Tekes established the five-year Wood Energy Technology Programme to stimulate the development of efficient systems for the large-scale production of forest chips. Key tar-gets are competitive costs, reliable supply and good quality chips. The two guiding principles of the programme are: (1) close cooperation between researchers and practitioners and (2) to apply research and development to the practical applications and commercialization.

Albuquerque, Priscilla B S; Malafaia, Carolina B

2018-02-01

Since the last two decades, the use of synthetic materials has increased and become more frequent in this capitalist system. Polymers used as raw materials are usually disposed very rapidly and considered serious damages when they return to the environment. Because of this behaviour, there was an increasing in the global awareness by minimizing the waste generated, in addition to the scientific community concern for technological alternatives to solve this problem. Alternatively, biodegradable polymers are attracting special interest due to their inherent properties, which are similar to the ones of the conventional plastics. Bioplastics covers plastics made from renewable resources, including plastics that biodegrade under controlled conditions at the end of their use phase. Polyhydroxyalkanoates (PHAs) are polyesters composed of hydroxy acids, synthesized by a variety of microorganisms as intracellular carbon and energy storage. These environmentally friendly biopolymers have excellent potential in domestic, agricultural, industrial and medical field, however their production on a large scale is still limited. This review considered the most recent scientific publications on the production of bioplastics based on PHAs, their structural characteristics and the exploitation of different renewable sources of raw materials. In addition, there were also considered the main biotechnological applications of these biopolymers. Copyright © 2017 Elsevier B.V. All rights reserved.

Song, Junnian; Yang, Wei; Higano, Yoshiro; Wang, Xian’en

2015-01-01

Highlights: • A dynamic input–output model is developed with bioenergy technologies complemented. • Availability of agricultural residues for bioenergy technologies is evaluated. • Trends in electricity and biofuel production are simulated dynamically. • Net profit and GHG mitigation contribution of bioenergy technologies are assessed. • Combustion power generation and briquette fuel are more advantageous. - Abstract: In order to facilitate regional agricultural residue utilization for energy production through bioenergy technologies, a dynamic input–output model is developed to estimate and assess the energy, economic and environmental performances of industrialization of five bioenergy technologies within a 15-year time horizon. Electricity and solid, gaseous and liquid biofuels are energy products of bioenergy technologies. Bioenergy technologies are complemented into regional input–output framework and combined with socioeconomic activities aided by their bottom-up economic and energy parameters. The simulation results for the target area indicate that the agricultural residues available for bioenergy technologies could amount to 55.16 million t, facilitating to 8.38 million t coal-equivalent bioenergy production by 2025. A 3.1% net reduction in accumulative greenhouse gas emission compared with the “business as usual” case could be achieved owing to substitution of fossil energy with electricity and biofuels produced by bioenergy technologies. From energy production, economic benefits and greenhouse gas mitigation three aspects integratedly, direct-combustion power generation and briquette fuel are more advantageous in the target area. The quantified energy, economic and environmental performances of bioenergy technologies are expected to give recommendations for their industrial development.

2018-04-01

Production technology for automotive lithium-ion battery (LIB) cells and packs has improved considerably in the past five years. However, the transfer of developments in materials, cell design and processes from lab scale to production scale remains a challenge due to the large number of consecutive process steps and the significant impact of material properties, electrode compositions and cell designs on processes. This requires an in-depth understanding of the individual production processes and their interactions, and pilot-scale investigations into process parameter selection and prototype cell production. Furthermore, emerging process concepts must be developed at lab and pilot scale that reduce production costs and improve cell performance. Here, we present an introductory summary of the state-of-the-art production technologies for automotive LIBs. We then discuss the key relationships between process, quality and performance, as well as explore the impact of materials and processes on scale and cost. Finally, future developments and innovations that aim to overcome the main challenges are presented.

2011-09-01

Full Text Available The availability of feed and their efficiency of use throughout the year represent the most important constraint affecting the productivity of animals in any agro-ecosystems. Beside being the largest contributor to the total production cost, logistically feeds need to be available on a daily basis across the animal’s life time. In order to be competitive, goat production system must be directed toward the optimum utilization of inconventional feedstuffs such as crop residues and agro-industrial by-products. The horticulture crops provide various crop-residues and by products from the processing of its main products. These biomass are potential feedstuffs that could be used to support the production of goats. The processing of passion fruits (Passiflora edulis yield by products such as fruit shells and seeds. These products are good energy and protein sources for growing goats. Oriental radish (Raphanus sativus by-products composed by damaged root parts and culls have high digestible energy and low ether extract content, but have very high moisture content. The pineapple by-products composed by the peel and bagasse of the fruit could be used as energy source for goats. Other horticulture by-products or residues such as citrus pulp, abandoned citrus fruit, forages from Ipomea batatas are of great potential as feeds for goat production. Preserving technology like ensiling could be implemented in utilising those biomass categorized as wet by-products such as pineapple and oriental radish by-products. The technology of complete feed is an effective means in utilizing some of those products with relatively low palatability or to increase its inclusion level in diets. Introducing shade-tolerant forage species as intercrops such as Stenotaphrum secundatum, Brachiaria humidicola and Arachis pintoi in the citrus plantation should increase feed capacity of the area. The multi-purpose trees such as Indigofera sp. and Calliandra calothyrsus both are

Full Text Available Cattle breeds have a striking effect on milk, including milk composition and technological characteristics. This study aims to compare milk composition, acidification activity, viscosity, milk dispersion system stability and casein molecular weight among three buffalo breeds in China. The technological characteristics of milk produced by three cattle breeds of river buffalo (Murrah, crossbreed 1st generation (F1, crossbreed multiple generation (FH, H≥3 buffaloes were investigated. Cattle breeds showed evident effect on milk protein, fat and total solids content, but little effect on most of buffalo casein molecular weight. Milk fat, protein content and the viscosity of buffalo milk from river buffalo were lower than those of F1 and FH, so was the buffer capacity. The viscosity was negatively correlated to temperature and concentration. Results of stability coefficient showed that milk dispersion system had the best dynamic stability characteristics under pH 6.6 and 6 times dilution, while zeta potential of Murrah milk was slightly higher than that of hybrid offspring (F1, FH. SDS-PAGE results showed that buffalo αs-casein had a slightly faster mobility than standard αs-casein; while buffalo β-casein showed a slightly slower mobility than standard β-casein. There is no clear differences in molecular weight of αs-, β-, and κ-casein among Murrah, F1 and FH.

New technology for production of granular adding material with nanomodifying additives for steel arc welding

Directory of Open Access Journals (Sweden)

BOLDYREV Alexander Mikhaylovich

2016-12-01

Full Text Available The chemical analysis of metal seam showed that introduction of titanium dioxide with MCA intensifies transition of Al2O3 from slag into metal pool and provides double concentration of titanium in the seam compared to the one which appears in the interaction of bathtub with melted flux AH-47 without TiO2 additives. The presence of oxides of titanium and aluminium of endogenous origin in the melt leads to formation of refractory particles with the center of TiO2 and Al2O3 in it. These particles are the centers of crystallization in the tail part of the molten pool and they remain in seam metal in the form of evenly distributed fine nonmetallic inclusions, which have crystallographic affinity with a matrix (α-iron. That provides the fine-grained seam structure with the raised and stable strength characteristics. This article compares the existing and developed technologies for production of MCA. The granulometric analysis of the powder TiO2 has demonstrated that when MCA is processed in the planetary mill, particles of titanium dioxide are crushed to a nanodimensional order. It is shown that the preparation of MCA in high-energy planetary mill (due to double increase of durability in coupling of the modifier with granulate provides its stable structure, increases the cold resistance (20–25% and stability of strength characteristics along the length of welded seam. Metalgraphic researches determined that the fine-grained structure which linear size of grain is twice smaller than the one obtained in the old technology welding is formed in a seam. However the direct introduction of nanomodifiers in a molten pool through the flux or an electrode wire is not efficient because of their deactivation and high temperature in welding zone. Therefore it was offered to use modifiers in the mix with the cooling macroparticles in case of automatic welding of a bridge metalware under flux using metalchemical additive (MCA. The MCA consists of a chopped
