    The growth of the US photovoltaics (PV) industry over the past decade has been impressive. First designed to provide power for satellites using high-cost production techniques, PV is now the economical choice in many remote terrestrial applications. The remarkable growth of PV in terms of quality of cells and modules, production techniques, and system design, was initiated by a cooperative effort of the US Government and the domestic PV manufacturers. European and Japanese firms entered the PV industry later, but are also growing rapidy. The Europeans continue to supply PV systems for village electrification and water pumping to many Third World countries. The Japanese have been developing the amorphous silicon (A-Si) technology by expanding its use in consumer goods. The world PV industry saw dramatic changes in industry ownership and in the emphasis on developing new and improved technology during 1984. The objective of this report is to present information on the developments of the world PV industry and focuses on developments occurring in 1984. Information is presented on a regional basis (US, Europe, Japan, other) to avoid disclosing company-confidential data. All information was gleaned from several sources, including a review of the technical literature and direct contacts with PV manufacturers. Prior to publishing the regional totals, all numbers were compared with those of other sources. The information contained in this report is prepared for use by the Department of Energy for their use in long-term R and D planning. However, this information should also be of interest by PV manufacturers and to those who may be contemplating entering the PV market. PV shipments for 1984, government supports for PV, and various PV market sectors are discussed.

    This paper offers micro-foundations for the dynamic relationship between technology and population in the pre-industrial world, accounting for both technological progress and the hitherto neglected but common phenomenon of technological regress. A positive feedback between population...... and the adoption of new techniques that increase the division of labor explains technological progress. A transient shock to productivity or population induces the neglect of some techniques rendered temporarily unprofitable, which are therefore not transmitted to the next generation. Productivity remains...... constrained by the smaller stock of knowledge and technology has thereby regressed. A slow process of rediscovery is required for the economy to reach its previous level of technological sophistication and population size. The model is employed to analyze specific historical examples of technological regress...

  13. Carbon Capture in the Cement Industry: Technologies, Progress, and Retrofitting.

    2016-01-05

    Several different carbon-capture technologies have been proposed for use in the cement industry. This paper reviews their attributes, the progress that has been made toward their commercialization, and the major challenges facing their retrofitting to existing cement plants. A technology readiness level (TRL) scale for carbon capture in the cement industry is developed. For application at cement plants, partial oxy-fuel combustion, amine scrubbing, and calcium looping are the most developed (TRL 6 being the pilot system demonstrated in relevant environment), followed by direct capture (TRL 4-5 being the component and system validation at lab-scale in a relevant environment) and full oxy-fuel combustion (TRL 4 being the component and system validation at lab-scale in a lab environment). Our review suggests that advancing to TRL 7 (demonstration in plant environment) seems to be a challenge for the industry, representing a major step up from TRL 6. The important attributes that a cement plant must have to be "carbon-capture ready" for each capture technology selection is evaluated. Common requirements are space around the preheater and precalciner section, access to CO2 transport infrastructure, and a retrofittable preheater tower. Evidence from the electricity generation sector suggests that carbon capture readiness is not always cost-effective. The similar durations of cement-plant renovation and capture-plant construction suggests that synchronizing these two actions may save considerable time and money.

    This report describes the current progress and status related to the Industry Application #2 focusing on External Hazards. For this industry application within the Light Water Reactor Sustainability (LWRS) Program Risk-Informed Safety Margin Characterization (RISMC) R&D Pathway, we will create the Risk-Informed Margin Management (RIMM) approach to represent meaningful (i.e., realistic facility representation) event scenarios and consequences by using an advanced 3D facility representation that will evaluate external hazards such as flooding and earthquakes in order to identify, model and analyze the appropriate physics that needs to be included to determine plant vulnerabilities related to external events; manage the communication and interactions between different physics modeling and analysis technologies; and develop the computational infrastructure through tools related to plant representation, scenario depiction, and physics prediction. One of the unique aspects of the RISMC approach is how it couples probabilistic approaches (the scenario) with mechanistic phenomena representation (the physics) through simulation. This simulation-based modeling allows decision makers to focus on a variety of safety, performance, or economic metrics. In this report, we describe the evaluation of various physics toolkits related to flooding representation. Ultimately, we will be coupling the flooding representation with other events such as earthquakes in order to provide coupled physics analysis for scenarios where interactions exist.

    2003-06-01

    The progress achieved by the multi-stakeholder solution gas flaring reduction program in Alberta is discussed. The program was initiated in 1999 by the Alberta Energy and Utilities Board (EUB); within the first three years upstream flaring of solution gas was reduced by 53 per cent. Progress has also been made in reducing volumes of solution gas venting: between 1996 and 2001, there has been a 32 per cent reduction in combined flared and vented volumes of solution gas. Well test flaring has also been reduced by reduced test durations and volumes, to wit: there has been a 3 per cent reduction in flaring volumes while well tests have increased by 23 per cent. At gas plants, the decrease in flaring and venting amounted to 19 per cent, attributed mostly to industry response to the EUB's Guide 60, which incorporates many of the recommendations of the 2002 report and recommendations of the Flaring/Venting Project Team of the Clean Air Strategic Alliance (CASA).

    2015-04-01

    The production of paper pulp by the Kraft method generates considerable amounts of wastes. Namely, lime mud generated in the recovery circuit of chemical reagents, biological sludge from the wastewater treatment of wood digestion process and fly ash collected in the fluidized bed combustor used to generate electricity from biomass burning. The final destination of such wastes is an important concern, since environmental regulations are becoming stricter regarding their landfill. Driven by this fact, industries are looking for more sustainable solutions, such as the recycling in distinct products. This work tested these wastes as secondary raw materials to produce clinker/cement that was then experienced in mortar formulations. The first step involved the residues detailed characterization and a generated amounts survey. Then, specific but simple steps were suggested, aiming to facilitate transport and manipulation. Distinct blends were prepared and fired in order to get belitic and Portland clinkers. The Portland clinkers were processed at lower temperatures than the normally used in the industry due to the presence of mineralizing impurities in some wastes. Belite-based cements were used to produce mortars that developed satisfactory mechanical strength and did not reveal signs of deterioration or durability weaknesses.

    The Advanced Industrial Materials (AIM) Program is a part of the Office of Industrial Technologies (OIT), Energy Efficiency and Renewable Energy, US Department of Energy (DOE). The mission of AIM is to support development and commercialization of new or improved materials to improve energy efficiency, productivity, product quality, and reduced waste in the major process industries. OIT has embarked on a fundamentally new way of working with industries--the Industries of the Future (IOF) strategy--concentrating on the major process industries that consume about 90% of the energy and generate about 90% of the waste in the industrial sector. These are the aluminum, chemical, forest products, glass, metalcasting, and steel industries. OIT has encouraged and assisted these industries in developing visions of what they will be like 20 or 30 years into the future, defining the drivers, technology needs, and barriers to realization of their visions. These visions provide a framework for development of technology roadmaps and implementation plans, some of which have been completed. The AIM Program supports IOF by conducting research and development on materials to solve problems identified in the roadmaps. This is done by National Laboratory/industry/university teams with the facilities and expertise needed to develop new and improved materials. Each project in the AIM Program has active industrial participation and support.

    In many ways, the Advanced Industrial Materials (AIM) Program underwent a major transformation in Fiscal Year 1995 and these changes have continued to the present. When the Program was established in 1990 as the Advanced Industrial Concepts (AIC) Materials Program, the mission was to conduct applied research and development to bring materials and processing technologies from the knowledge derived from basic research to the maturity required for the end use sectors for commercialization. In 1995, the Office of Industrial Technologies (OIT) made radical changes in structure and procedures. All technology development was directed toward the seven ``Vision Industries`` that use about 80% of industrial energy and generated about 90% of industrial wastes. The mission of AIM has, therefore, changed to ``Support development and commercialization of new or improved materials to improve productivity, product quality, and energy efficiency in the major process industries.`` Though AIM remains essentially a National Laboratory Program, it is essential that each project have industrial partners, including suppliers to, and customers of, the seven industries. Now, well into FY 1996, the transition is nearly complete and the AIM Program remains reasonably healthy and productive, thanks to the superb investigators and Laboratory Program Managers. This Annual Report for FY 1995 contains the technical details of some very remarkable work by the best materials scientists and engineers in the world. Areas covered here are: advanced metals and composites; advanced ceramics and composites; polymers and biobased materials; and new materials and processes.

    2014-09-01

    In this paper, we present the possibility of using fly ash to produce synthetic zeolites. The synthesis class F fly ash from the Stalowa Wola SA heat and power plant was subjected to 24 h hydrothermal reaction with sodium hydroxide. Depending on the reaction conditions, three types of synthetic zeolites were formed: Na-X (20 g fly ash, 0.5 dm(3) of 3 mol · dm(-3) NaOH, 75 °C), Na-P1 (20 g fly ash, 0.5 dm(3) of 3 mol · dm(-3) NaOH, 95 °C), and sodalite (20 g fly ash, 0.8 dm(3) of 5 mol · dm(-3) NaOH + 0.4 dm(3) of 3 mol · dm(-3) NaCl, 95 °C). As synthesized materials were characterized to obtain mineral composition (X-ray diffractometry, Scanning electron microscopy-energy dispersive spectrometry), adsorption properties (Brunauer-Emmett-Teller surface area, N2 isotherm adsorption/desorption), and ion exchange capacity. The most effective reaction for zeolite preparation was when sodalite was formed and the quantitative content of zeolite from X-ray diffractometry was 90 wt%, compared with 70 wt% for the Na-X and 75 wt% for the Na-P1. Residues from each synthesis reaction were the following: mullite, quartz, and the remains of amorphous aluminosilicate glass. The best zeolitic material as characterized by highest specific surface area was Na-X at almost 166 m(2) · g(-1), while for the Na-P1 and sodalite it was 71 and 33 m(2) · g(-1), respectively. The ion exchange capacity decreased in the following order: Na-X at 1.8 meq · g(-1), Na-P1 at 0.72 meq · g(-1), and sodalite at 0.56 meq · g(-1). The resulting zeolites are competitive for commercially available materials and are used as ion exchangers in industrial wastewater and soil decontamination.

    Cyanobacteria hold significant potential as industrial biotechnology (IB) platforms for the production of a wide variety of bio-products ranging from biofuels such as hydrogen, alcohols and isoprenoids, to high-value bioactive and recombinant proteins. Underpinning this technology, are the recent advances in cyanobacterial “omics” research, the development of improved genetic engineering tools for key species, and the emerging field of cyanobacterial synthetic biology. These approaches enabled the development of elaborate metabolic engineering programs aimed at creating designer strains tailored for different IB applications. In this review, we provide an overview of the current status of the fields of cyanobacterial omics and genetic engineering with specific focus on the current molecular tools and technologies that have been developed in the past five years. The paper concludes by giving insights on future commercial applications of cyanobacteria and highlights the challenges that need to be addressed in order to make cyanobacterial industrial biotechnology more feasible in the near future.

    Cosmic-ray produced muons arrive at the surface of the earth with enormous energies ranging up to 1012 GeV. There have been sporadic attempts to exploit their extreme penetration through matter to probe the internal structures of very large objects, including an Egyptian pyramid and a volcano but their very low intensity per unit area ( ≈1 cm-2 per min) generally restricts the practicably attainable spatial resolution to large dimensions. Nevertheless the more intense low energy region of the muon spectrum has recently been shown to be capable of detecting high-Z objects with dimensions of the order of 10 cm hidden inside large transport containers in measurement times of minutes. These various developments have encouraged further studies of potential industrial uses of cosmic-ray muons in industrial applications. In order to gain maximum benefit from the low muon flux large area detectors are required and plastic scintillators offer useful advantages in size, cost and simplicity. Scintillator slabs up to 1 m2 square and 76.2 mm thick are undergoing testing for applications in the nuclear industry. The most direct approach employs photomultiplier tubes at each corner to measure the relative sizes of muon induced pulses to determine the location of each muon track passing through the scintillator. The performance of this technique is reported and its imaging potential is assessed.

    2016-01-01

    Full Text Available With an increase in the population and industrialization, a lot of valuable natural resources are depleted to prepare and manufacture products. However industrialization on the other hand has waste disposal issues, causing dust and environmental pollution. In this work, Aluminium Metal Matrix Composite is prepared by reinforcing 10 wt% and 20 wt% of wet grinder stone dust particles an industrial waste obtained during processing of quarry rocks which are available in nature. In the composite materials design wear is a very important criterion requiring consideration which ensures the materials reliability in applications where they come in contact with the environment and other surfaces. Dry sliding wear test was carried out using pin-on-disc apparatus on the prepared composites. The results reveal that increasing the reinforcement content from 10 wt% to 20 wt% increases the resistance to wear rate.

  1. Use of Whey and Whey Preparations in the Food Industry – A Review

    Directory of Open Access Journals (Sweden)

    Królczyk Jolanta B.

    2016-07-01

    Full Text Available The interest in whey and whey preparations has considerably increased in recent years. Whey and whey preparations are the so-called “forgotten treasure” and, because of their unique properties, they have been “rediscovered” and have been increasingly frequently and successfully used by various production plants in the food industry. They have also been eagerly purchased by consumers who are aware of the role of whey preparations in adequate human nutrition. For many years, there has been a tendency in the food processing industry to use substitutes of ingredients in recipes of many products. This situation can be observed in the case of foods with reduced fat and sugar, or products for lacto-ovo-vegetarians. Whey - and more specifically, its preparations - can also be used as a substitute. According to many literature sources, its use can have a positive impact not only on the consumers’ health but also on the finances of many companies, by reducing the costs of raw materials, and thus production costs. This review paper presents selected uses of whey and whey preparations in the food industry. The uses of whey discussed include: meat and meat products, reduced-fat products, yoghurts and ice creams, cheeses, bakery products, confectionery and pastry products, infant formulas, and whey drinks.

    Subjectivity usually causes large fluctuations in evaluation results. Many scholars attempt to establish new mathematical methods to make evaluation results consistent with actual objective situations. An improved catastrophe progression method (ICPM) is constructed to overcome the defects of the original method. The improved method combines the merits of the principal component analysis' information coherence and the catastrophe progression method's none index weight and has the advantage of highly objective comprehensive evaluation. Through the systematic analysis of the influencing factors of the automotive industry's core technology capacity, the comprehensive evaluation model is established according to the different roles that different indices play in evaluating the overall goal with a hierarchical structure. Moreover, ICPM is developed for evaluating the automotive industry's core technology capacity for the typical seven countries in the world, which demonstrates the effectiveness of the method.

    1991-03-01

    Since 1989, the U.S. Department of Energy has sponsored the Energy Efficient Industrialized Housing research program (EEIH) to improve the energy efficiency of industrialized housing. Two research centers share responsibility for this program: The Center for Housing Innovation at the University of Oregon and the Florida Solar Energy Center, a research institute of the University of Central Florida. Additional funding is provided through the participation of private industry, state governments and utilities. The program is guided by a steering committee comprised of industry and government representatives. This report summarizes Fiscal Year (FY) 1990 activities and progress, and proposed activities for FY 1991 in Task 2.1 Design for Energy Efficiency. This task establishes a vision of energy conservation opportunities in critical regions, market segments, climate zones and manufacturing strategies significant to industrialized housing in the 21st Century. In early FY 1990, four problem statements were developed to define future housing demand scenarios inclusive of issues of energy efficiency, housing design and manufacturing. Literature surveys were completed to assess seven areas of influence for industrialized housing and energy conservation in the future. Fifty-five future trends were identified in computing and design process; manufacturing process; construction materials, components and systems; energy and environment; demographic context; economic context; and planning policy and regulatory context.

    2007-01-01

    The rebound effects of technological advancement on energy consumption make it very complicated to measure the impact of technological advancement on energy efficiency.This article,taking 35 industries as samples,utilizes the non-parameter DEA-Malmquist productivity approach to subcategorise technological advancement into three parts:science-technological(sci-tech)progress,pure technical efficiency and efficiency of scale.The panel technique is then used to work out each subcategory’s contribution to energy efficiency individually.Findings show that technological efficiency (calculated by multiplying the results of pure technical efficiency and scale efficiency)is the principal factor in the improvement of energy efficiency while the contribution from sci-tech progress is comparatively less.Overtime,however,the effect of sci-tech progress is gradually heightened while the effect of technical efficiency slowly diminishes.

  7. Preparation of MCM-41 in Industrial Scale and Its Application in Heavy Oil Processing

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    A series of MCM-41 molecular sieves have been prepared on an industrial scale, and the effect of preparation factors such as aging temperature, pH values on the structure and pore distribution of the MCM-41 product have been studied by using X-ray diffraction(XRD), thermogravimetric(TG) and electron microscopy (TEM). It is shown that the pH values have a significant effect on the crystallinity of the synthesized product. Under proper conditions, the MCM-41 prepared on an industrial scale has the same performance as the samples prepared on an Lab-scale. The prepared MCM-41 was used as a modifier of zeolite Y for fluid catalytic cracking (FCC) of residual oil. It is shown that the addition of the MCM-41 in the zeolite Y catalyst increases the pore size, and surface area of the catalysts, which helps to increase the yield of gasoline and diesel and decrease the production of gaseous product and carbon deposition in the catalyst. The better performance of the MCM-41 modified zeolite Y catalyst is believed to be due to its adjustment on the acidity and increase of the pore size.

    Chen Shouhai; Zhang Baosheng

    2009-01-01

    Relaxation of control over the upstream business of the petroleum industry in China is discussed. The authors suggest that a basic institutional preparation should be made before relaxing control over the upstream business, and that the institutional preparation includes at least four parts: 1) setting up the admission standards, 2) perfecting the management system of mining rights, 3) reforming the royalty and taxation system for oil and gas resources, and 4) improving the supervision and management system. Stressing the institutional preparation before relaxation of control does not mean that China could not relax control over the upstream business until the management systems are perfected, but the authors suggest that China could establish a necessary system for relaxation of control and to improve it with future practice.

    2011-03-01

    Seven years ago, the Strategic Programs for Innovations in Undergraduate Physics (SPIN-UP) Report produced by the National Task Force on Undergraduate Physics identified several key characteristics of thriving undergraduate physics departments including steps these departments had taken to prepare students better for careers in industry. Today statistical data from AIP shows that almost 40% of students graduating with a degree in physics seek employment as soon as they graduate. Successful undergraduate physics programs have taken steps to adapt their rigorous physics programs to ensure that graduating seniors have the skills they need to enter the industrial workplace as well as to go on to graduate school in physics. Typical strategies noted during a series of SPIN-UP workshops funded by a grant from NSF to APS, AAPT, and AIP include flexible curricula, early introduction of undergraduates to research techniques, revised laboratory experiences that provide students with skills they need to move directly into jobs, and increased emphasis on ``soft'' skills such as communication and team work. Despite significant success, undergraduate programs face continuing challenges in preparing students to work in industry, most significantly the fact that there is no job called ``physicist'' at the undergraduate level. supported by grant NSF DUE-0741560.

    The recent growth of biotechnology requires a wide range of expertise within the industry. Education is the primary platform for students to gain information and knowledge on biotechnology. In Malaysia where biotechnology is relatively new, education programs and courses must be tailored to meet the demands of the industry. A combination of theoretical knowledge as well as practical and industrial training is essential to ensure graduates are prepared for their career in the fields of biotechnology. Results from this study show that university students lack literacy on biotechnology information and access to facilities provided by the universities. This may be a significant contributing factor to the lack of knowledge and information amongst graduates. Furthermore comparative analysis on the biotechnology program in Malaysian universities with that of other countries show the need to restructure the program by offering more specialized courses as well as soft skills and business subjects. This is to meet the demands of the related professionals as well as the various branches that exist in the biotechnology industry. © 2015 The International Union of Biochemistry and Molecular Biology.

    2004-01-01

    Three kinds of craft waste liquids, which are by-products in the pulp industry and contain much lignin,were used as dispersing additives for preparing Horonai coal CWM (coal water mixture). The experiments showed that the CWM exhibited the lowest viscosity when it was diluted with an appropriate amount of water with the waste eiquids added. The experiments also indicated that the maximum coal concentration in the 62.5% (mass fraction), and 56.5% is the maximum coal mass fraction of the CWM prepared without additives. These data show the effectiveness of the waste liquids as the additives for preparing CWMs. The zeta potential of coal particles in the CWMs changed with the addition of lignin. From the change, the steric repulsion effect of the lignin adsorbed on the coal particles is concluded to be mainly responsible for the CWM dispersion. The waste liquids contain less sulfur than PSSNa(polystyrene sulfonate sodium salt), a typical dispersant which is currently used for preparing the commercial CWM, when the sulfur content in the unit mass of the solid matters within the waste liquids is compared with that in unit mass of PSSNa. This fact suggests that the waste liquids are more advantageous than PSSNa as far as air pollutants are concerned.

WCE is a novel breakthrough in the biomedical industry and future progresses in key technologies, expected to drive the development of the next generation of such devices. WCE became an essential component in the management of several clinical conditions. WCE offers diagnostic tool for diseases like small bowel, gastrointestinal bleeding, Crohn's disease, localization of small bowel tumor, colon cancer screening, assessment of esophageal disorders and diagnosis of coeliac disease. However, compared with wired endoscopies, the limited working time, the low frame rate and the low image resolution limit the wider application. The progress of this new technology is reviewed in this paper and the evolution tendencies are analyzed to be high image resolution, high frame rate, long working time and also current indications of capsule endoscopy.

    Molecularly imprinted polymers (MIPs) are biomimetics which can selectively bind to analytes of interest. One of the most interesting areas where MIPs have shown the biggest potential is food analysis. MIPs have found use as sorbents in sample preparation attributed to the high selectivity and high loading capacity. MIPs have been intensively employed in classical solid-phase extraction and solid-phase microextraction. More recently, MIPs have been combined with magnetic bead extraction, which greatly simplifies sample handling procedures. Studies have consistently shown that MIPs can effectively minimize complex food matrix effects, and improve recoveries and detection limits. In addition to sample preparation, MIPs have also been viewed as promising alternatives to bio-receptors due to the inherent molecular recognition abilities and the high stability in harsh chemical and physical conditions. MIPs have been utilized as receptors in biosensing platforms such as electrochemical, optical and mass biosensors to detect various analytes in food. In this review, we will discuss the current state-of-the-art of MIP synthesis and applications in the context of food analysis. We will highlight the imprinting methods which are applicable for imprinting food templates, summarize the recent progress in using MIPs for preparing and analysing food samples, and discuss the current limitations in the commercialisation of MIPs technology. Finally, future perspectives will be given.

    A typical superhydrophobic (ultrahydrophobic) surface can repel water droplets from wetting itself, and the contact angle of a water droplet resting on a superhydrophobic surface is greater than 150°, which means extremely low wettability is achievable on superhydrophobic surfaces. Many superhydrophobic surfaces (both manmade and natural) normally exhibit micro- or nanosized roughness as well as hierarchical structure, which somehow can influence the surface's water repellence. As the research into superhydrophobic surfaces goes deeper and wider, it is becoming more important to both academic fields and industrial applications. In this work, the most recent progress in preparing manmade superhydrophobic surfaces through a variety of methodologies, particularly within the past several years, and the fundamental theories of wetting phenomena related to superhydrophobic surfaces are reviewed. We also discuss the perspective of natural superhydrophobic surfaces utilized as mimicking models. The discussion focuses on how the superhydrophobic property is promoted on solid surfaces and emphasizes the effect of surface roughness and structure in particular. This review aims to enable researchers to perceive the inner principles of wetting phenomena and employ suitable methods for creation and modification of superhydrophobic surfaces.

    Full Text Available Alite-ye'elimite clinker is a high cementing clinker that is prepared by introducing calcium sulfoaluminate, a non-silicate mineral, into cement clinker. The industrial residue was used to produce cement clinker. The relationship of the aluminate modulus (IM and the mineral composition and mechanics of tricalcium silicate-rich sulfur aluminate cement is reported. The effects of the aluminate modulus on the phase compositions, morphology and compressive strength were investigated. The phase morphology was analyzed by optical microscopy. The results show that the increase of IM in the clink can accelerate the formation of calcium sulfoaluminate; calcium sulfoaluminate can form at the temperature of 1250 °C when the IM value is lower than 2.50, while it exists at a temperature of 1300 °C without reheating when the IM value is higher than 2.50.

    Aonla is an important Indian fruit crop with great potential for processing into various quality products. Aonla preserve making is an important economic activity in our country. The pricking methods are age old, hence a hand operated aonla pricking machine was introduced in preserve making industries to speed up the pricking task. OWAS and RULA two of the most commonly used ergonomic assessment tools were evaluated for their efficacy in the assessment pricking along with Rating of perceived exertion scale. Analysis of working posture using RULA revealed that the pricking task with existing methods i.e. fork and hand tool requires immediate investigation and changes in working posture while with machine pricking investigations and changes are required soon. The results of OWAS indicated that the posture maintained while pricking with existing methods need to be changed in future planning while with machine was acceptable. The subjective assessment revealed that machine pricking was less exerting activity as compared to the existing methods. The preserve prepared from machine pricked fruit was most acceptable among consumers. Hence, in the form of machine ergonomic intervention was brought about in preservation industries which have proved beneficial for workers in terms of their safety and productivity.

    We aimed to develop a simple and low-cost method for the production of high-performance cellulose nanomaterials from renewable and sustainable resources. Here, cellulose microcrystals (CMCs) were prepared by controlled acidic and basic hydrolysis of cotton from textile industry wastes. The resulted CMCs were further converted into cellulose nanocrystals (CNCs) with high crystallinity by acidic hydrolysis. The physicochemical characteristics and morphological feature of CMCs and CNCs were studied by various analytical techniques such as UV-vis spectroscopy, Fourier-transform infrared spectroscopy (FT-IR), Scanning electron microscope (SEM), Fluorescence spectroscopy, Atomic force microscopy (AFM), High-resolution transmission electron microscopy (HR-TEM), X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD). The isolated CNCs possess a needle-like morphological structure with the longitudinal and lateral dimensions of 180 ± 60 nm, 10 ± 1 nm, respectively. The AFM result reveals that the CNCs have a high aspect ratio of 40 ± 14 nm and the average thickness of 6.5 nm. The XRD and TEM analysis indicate that the synthesized CNCs possess face-centered cubic crystal structure. Preliminary experiments were carried out to fabricate CNCs incorporated poly (vinyl alcohol) (PVA) film. The results suggest that the concept of waste to wealth could be well executed from the prepared CNCs, which have great potential for various applications including bio-sensors, food packaging and drug delivery applications.

    Boric acid is often added into coolant as neutron capture agent for pressurized water reactor, whose amount is influenced by its abundance and purity. Therefore, the preparation of enriched (10)B boric acid with high purity is beneficial to nuclear industry. (10)B is also used in developing tumor-specific boronated drugs in boron neutron capture therapy. The boronated drug can be administered to patient intravenously, intratumorally, or deposited at tumor site in surgical excision. Thus, enriched (10)B boric acid is of practical significance in the field of medicine. Self-made boron trifluoride-methanol-complex solution was selected as one of the experimental reagents, and the preparation of (10)B acid was realized by one-step reaction for the complexes with water and calcium chloride. The determination of electrical conductivity in reaction process proves that the optimum reaction time was 16-20 h. Furthermore, the effect of reaction time, ratio of calcium chloride to complex as well as the amount of water on the purity and yield of boric acid was investigated. Finally, the optimum reaction time was 20 h, the optimal solid-liquid ratio (molar ratio) was 3:1, and the amount of water was 1 L of deionized water for each mol of the complex. H2O2 was added in the reaction process to remove Fe(2+). After recrystallization, IR spectra of (10)B boric acid was measured and compared with standard to verify the product of boric acid. The feasibility of the preparation method was determined by the detection of XRD of boric acid. To observe the morphology by polarizing microscope, crystal structure was obtained. The purity of the final product is 99.95 %, and the yield is 96.47 %. The ion concentration of boric acid accords with the national standard of high purity, which was determined by ICP.

    Fermentation and cell culture biotechnology in the form of so-called "cell factories" now play an increasingly significant role in production of both large (e.g. proteins, biopharmaceuticals) and small organic molecules for a wide variety of applications. However, associated metabolic engineering optimisation processes relying on genetic modification of organisms used in cell factories, or alteration of production conditions remain a challenging undertaking for improving the final yield and quality of cell factory products. In addition to genomic, transcriptomic and proteomic workflows, analytical metabolomics continues to play a critical role in studying detailed aspects of critical pathways (e.g. via targeted quantification of metabolites), identification of biosynthetic intermediates, and also for phenotype differentiation and the elucidation of previously unknown pathways (e.g. via non-targeted strategies). However, the diversity of primary and secondary metabolites and the broad concentration ranges encompassed during typical biotechnological processes means that simultaneous extraction and robust analytical determination of all parts of interest of the metabolome is effectively impossible. As the integration of metabolome data with transcriptome and proteome data is an essential goal of both targeted and non-targeted methods addressing production optimisation goals, additional sample preparation steps beyond necessary sampling, quenching and extraction protocols including clean-up, analyte enrichment, and derivatisation are important considerations for some classes of metabolites, especially those present in low concentrations or exhibiting poor stability. This contribution critically assesses the potential of current sample preparation strategies applied in metabolomic studies of industrially-relevant cell factory organisms using mass spectrometry-based platforms primarily coupled to liquid-phase sample introduction (i.e. flow injection, liquid

  10. Do new cellulolytic enzyme preparations affect the industrial strategies for high solids lignocellulosic ethanol production?

    2014-01-01

    Production of ethanol from lignocellulosic materials has a promising market potential, but the process is still only at pilot/demonstration scale due to the technical and economical difficulties of the process. Operating the process at very high solids concentrations (above 20% dry matter-DM) has proven essential for economic feasibility at industrial scale. Historically, simultaneous saccharification and fermentation (SSF) was found to give better ethanol yields compared to separate hydrolysis and fermentation (SHF), but data in literature are typically based on operating the process at low dry matter conditions. In this work the impact of selected enzyme preparation and processing strategy (SHF, presaccharification and simultaneous saccharification and fermentation-PSSF, and SSF) on final ethanol yield and overall performance was investigated with pretreated wheat straw up to 30% DM. The experiments revealed that an SSF strategy was indeed better than SHF when applying an older generation enzyme cocktail (Celluclast-Novozym 188). In case of the newer product Cellic CTec 2, SHF resulted in 20% higher final ethanol yield compared to SSF. It was possible to close the mass balance around cellulose to around 94%, revealing that the most relevant products could be accounted for. One observation was the presence of oxidized sugar (gluconic acid) upon enzymatic hydrolysis with the latest enzyme preparation. Experiments showed gluconic acid formation by recently discovered enzymatic class of lytic polysaccharides monoxygenases (LPMO's) to be depending on the processing strategy. The lowest concentration was achieved in SSF, which could be correlated with less available oxygen due to simultaneous oxygen consumption by the yeast. Quantity of glycerol and cell mass was also depending on the selected processing strategy.

    A new value-added material was developed from wastes to aim for appropriate waste management and sustainable development. This paper reports the valorization of industrial sandblasting operation wastes (SOWs) as new photocatalytic materials. This waste is composed of Fe2 O3 (60.7 %), SiO2 (29.1 %), and Al2 O3 (3.9 %) as the main components. The high presence of iron oxides was used to develop photocatalytic properties through their thermal transformation into α-Fe2 O3 . The new product, SOW-T, exhibited a good behavior towards the photochemical degradation of organic dyes. The preparation of advanced photocatalytic materials that exhibit self-cleaning and depolluting properties was possible by the inclusion of SOW-T and TiO2 in a cement-based mortar. The synergy observed between both materials enhanced their photocatalytic action. To the best of our knowledge, this is the first report that describes the use of transformed wastes based on iron oxide for the photochemical oxidation of NOx gases.

    Cassava peel is an agro-industrial waste which is available in huge quantities in Lampung Province of Indonesia. This work was conducted to evaluate the potential of cassava peel as a source of cellulose and nanocellulose. Cellulose was extracted from cassava peel by using different chemical treatment, and the nanocellulose was prepared by hydrolysis with the use of sulfuric acid. The best methods of cellulose extraction from cassava peels are using alkali treatment followed by a bleaching process. The cellulose yield from this methods was 17.8% of dry base cassava peel, while the yield from nitric and sulfuric methods were about 10.78% and 10.32% of dry base cassava peel respectively. The hydrolysis was performed at the temperature of 50 °C for 2 hours. The intermediate reaction product obtained after each stage of the treatments was characterized. Fourier transform infrared spectroscopy showed the removal of non-cellulosic constituent. X-ray Diffraction (XRD) analysis revealed that the crystallinity of cellulose increased after hydrolysis. Morphological investigation was performed using Scanning Electron Microscopy (SEM). The size of particle was confirmed by Particle Size Analyzer (PSA) and Transmission Electron Microscopy (TEM).

    This chapter addresses past, ongoing, and short (to 2010) and medium-term (to 2030) future actions that can be taken to mitigate GHG emissions from the manufacturing and process industries. Globally, and in most countries, CO{sub 2} accounts for more than 90% of CO{sub 2}-eq GHG emissions from the industrial sector (Price et al., 2006; US EPA, 2006b). These CO{sub 2} emissions arise from three sources: (1) the use of fossil fuels for energy, either directly by industry for heat and power generation or indirectly in the generation of purchased electricity and steam; (2) non-energy uses of fossil fuels in chemical processing and metal smelting; and (3) non-fossil fuel sources, for example cement and lime manufacture. Industrial processes also emit other GHGs, e.g.: (1) Nitrous oxide (N{sub 2}O) is emitted as a byproduct of adipic acid, nitric acid and caprolactam production; (2) HFC-23 is emitted as a byproduct of HCFC-22 production, a refrigerant, and also used in fluoroplastics manufacture; (3) Perfluorocarbons (PFCs) are emitted as byproducts of aluminium smelting and in semiconductor manufacture; (4) Sulphur hexafluoride (SF{sub 6}) is emitted in the manufacture, use and, decommissioning of gas insulated electrical switchgear, during the production of flat screen panels and semiconductors, from magnesium die casting and other industrial applications; (5) Methane (CH{sub 4}) is emitted as a byproduct of some chemical processes; and (6) CH{sub 4} and N{sub 2}O can be emitted by food industry waste streams. Many GHG emission mitigation options have been developed for the industrial sector. They fall into three categories: operating procedures, sector-wide technologies and process-specific technologies. A sampling of these options is discussed in Sections 7.2-7.4. The short- and medium-term potential for and cost of all classes of options are discussed in Section 7.5, barriers to the application of these options are addressed in Section 7.6 and the implication of

    Ni, Ye; Sun, Zhihao

    2009-06-01

    China is one of the few countries, which maintained the fermentative acetone-butanol-ethanol (ABE) production for several decades. Until the end of the last century, the ABE fermentation from grain was operated in a few industrial scale plants. Due to the strong competition from the petrochemical industries, the fermentative ABE production lost its position in the 1990s, when all the solvent fermentation plants in China were closed. Under the current circumstances of concern about energy limitations and environmental pollution, new opportunities have emerged for the traditional ABE fermentation industry since it could again be potentially competitive with chemical synthesis. From 2006, several ABE fermentation plants in China have resumed production. The total solvent (acetone, butanol, and ethanol) production capacity from ten plants reached 210,000 tons, and the total solvent production is expected to be extended to 1,000,000 tons (based on the available data as of Sept. 2008). This article reviews current work in strain development, the continuous fermentation process, solvent recovery, and economic evaluation of ABE process in China. Challenges for an economically competitive ABE process in the future are also discussed.

    This review summarizes recent advances in synthesis routes for quickly and reliably making and functionalizing magnetic nanoparticles for applications in biomedicine. We put special emphasis on describing synthetic strategies that result in the production of nanosized materials with well-defined physical and crystallochemical characteristics as well as colloidal and magnetic properties. Rather than grouping the information according to the synthetic route, we have described methods to prepare water-dispersible equiaxial magnetic nanoparticles with sizes below about 10 nm, sizes between 10 and 30 nm and sizes around the monodomain-multidomain magnetic transition. We have also described some recent examples reporting the preparation of anisometric nanoparticles as well as methods to prepare magnetic nanosized materials other than iron oxide ferrites, for example Co and Mn ferrite, FePt and manganites. Finally, we have described examples of the preparation of multicomponent systems with purely inorganic or organic-inorganic characteristics. (topical review)

    Strecker, A; Kelsch, M; Salzberger, U; Sycha, M; Gao, M; Richter, G; Benthem, K V

    2003-01-01

    In transmission electron microscopy (TEM), often the preparation of samples is the most critical part. Specimens have to have disk geometries of 3 mm diameter laterally, and they have to be transparent for the electron beam vertically. Therefore, a specimen thickness in the range of some 1-10 nm has to be achieved by the preparation process. While shrinking the specimen dimensions, care has to be taken to recover the materials properties in the nm-regime. We report and shortly discuss some TEM specimen preparation techniques mainly used in the Stuttgart TEM specimen preparation laboratory. Furthermore, we demonstrate how more advanced techniques lead to a more reliable preparation of weakly-bonded metal/SrTiO sub 3 interfaces. In addition, the advantage of low-voltage ion-milling is demonstrated by a case study for bulk SrTiO sub 3. As a result, low-voltage ion polishing as a final step in the TEM specimen preparation by conventional ion-thinning turns out to significantly increase the specimen quality. In tu...

    Post-industrial plastic waste streams can be re-used as secondary material streams for polymer processing by extrusion or injection moulding. One of the major commercially available waste stream contains polypropylene (PP) contaminated with polyesters (mostly polyethylene tereftalate - PET). An important practical hurdle for the direct implementation of this waste stream is the immiscibility of PP and PET in the melt, which leads to segregation within the polymer structure and adversely affects the reproducibility and mechanical properties of the manufactured parts. It has been indicated in literature that the creation of PET microfibrils in the PP matrix could undo these drawbacks and upcycle the PP/PET combination. Within the current research, a commercially available virgin PP/PET was evaluated for the microfibrillar preparation. The mechanical (tensile and impact) properties, thermal properties and morphology of the composites were characterized at different stages of the microfibrillar preparation.

    Pure hydroxyappatite Ca10(PO4)6(OH)2 (or HAP) was prepared from eggshell and potassium dihydrogen phosphate (KH2PO4) by a simple self-chemical reaction method. The clean eggshell was heated at 800 °C in air giving the source of CaO. Appropriate amount of CaO was dissolved in KH2PO4 solution at 37°C for few days. The PH value decreases with increasing the duration of preparation of HAP. Silver nanoparticles derived from silver nitrate solution using black tea leaf extract had been introduced to hydroxyapatite due to its biocompatibility. The unique size- dependent properties of nanomaterials make them superior and indispensable. In this work, hydroxyapatite-silver nanoparticles/polyvinyl alcohol (PVA) composites with 4 different concentrations of hydroxyapatite (1-4 wt %) were prepared by bio-reduction method. Several techniques like XRD and SEM were used to characterize the prepared samples. Frequency dependent capacitance and conductance of the samples were measured using an impedance analyzer. The results showed a remarkable increase in dielectric permittivity (~5117) with low loss (~0.23) at1000 HZ and room temperature (300K) for 4wt% Hydroxapatie-Silver/PVA nanocomposite. Such nanocomposite might be directly applied in manufacturing clinical devices and also for embedding capacitor applications.

    Oil-in-water (O/W) nanoemulsions play an important key role in transporting bioactive compounds into a range of cosmeceutical products to the skin. Small droplet sizes have an inherent stability against creaming, sedimentation, flocculation, and coalescence. O/W emulsions varying in manufacturing process were prepared. The preparation and characterization of O/W nanoemulsions with average diameters of as low as 62.99 nm from palm oil esters were carried out. This was achieved using rotor-stator homogenizer and ultrasonic cavitation. Ultrasonic cell was utilized for the emulsification of palm oil esters and water in the presence of mixed surfactants, Tween 80 and Span 80 emulsions with a mean droplet size of 62.99 nm and zeta potential value at -37.8 mV. Results were comparable with emulsions prepared with rotor-stator homogenizer operated at 6000 rpm for 5 min. The stability of the emulsions was evaluated through rheology measurement properties. This included non-Newtonian viscosity, elastic modulus G', and loss modulus G″. A highly stable emulsion was prepared using ultrasonic cavitation comprising a very small particle size with higher zeta potential value and G' > G″ demonstrating gel-like behavior.

    Full Text Available Elimination of heavy metals like nickel from waste water is an important subject in view of public health. In the present study, an attempt has been made to study the applicability of industrial by-products as potential metal adsorbents to remove nickel from aqueous solutions and polluted water. A direct proportionality between the percentage of Ni(II removal and adsorbent dosage was noted. Maximum removal ⁄ recovery of nickel was achieved at pH range of 10-12 for all adsorbents. An optimum temperature of 40 °C for efficient removal of Ni(II was observed. The effect of nickel adsorption was affected by salinity. The adsorption isotherm data confirmed to Freundlich and Langmuir isotherms. Conformation of data to the Lagergren᾽s rate equation indicated first order kinetics. The suitability of the industrial by-products in the successful removal of nickel from aqueous solution is quite obvious from the study.

  16. Regulation and market power in the Spanish liquefied petroleum gas industry: Progress or failure?

    Energy Technology Data Exchange (ETDEWEB)

    Bello, Alejandro; Huerta, Emilio [Departamento de Gestion de Empresas, Universidad Publica de Navarra, Campus de Arrosadia, 31006 Pamplona, Navarra (Spain)

    2007-07-15

    This paper presents a detailed study of the structure, market power and competition in the distribution sector for liquefied petroleum gas (LPG), within Spain. It is a segment of energy consumption and supply that is not often given serious attention, despite the fact that LPG is a crucial source of energy to many households, in many countries in Europe and in the rest of the world. Despite formally being an open and liberalized sector, the Spanish LPG market is characterized by high concentration within the industry; Repsol Butano, the dominant operator, practically controls the entire value chain. These structural characteristics probably justify state intervention in the form of price fixing, in order to guarantee accessible prices for final consumers. Nevertheless, applying this tool has had negative effects on the opening and liberalization process. On the one hand, it fails to encourage entry or an increase in the participation of new operators; on the other, it has considerably deteriorated the economic and financial performance of the distribution agents that are subjected to two strong forces. First, the dominant operator looks after its own interests and its income; and second, the Government tries to defend the interests of final consumers by fixing prices that inadequately remunerate the activity. This shows the contradictory regulatory actions that try to promote competition, and then establish mechanisms to regulate activity by fixing prices that act as price limits. These government set prices discourage new competitors from entering. (author)

  4. Extreme events: being prepared for the pitfalls with progressing sustainable urban water management.

    Science.gov (United States)

    Keath, N A; Brown, R R

    2009-01-01

    It is widely accepted that new, more sustainable approaches to urban water management are required if cities and ecosystems are to become resilient to the effects of growing urban populations and global warming. Climate change predictions show that it is likely that cities around the world will be subject to an increasing number of extreme and less predictable events including flooding and drought. Historical transition studies have shown that major events such as extremes can expedite the adoption of new practices by destabilising existing management regimes and opening up new windows of opportunity for change. Yet, they can also act to reinforce and further entrench old practices. This case study of two Australian cities responding to extreme water scarcity reveals that being unprepared for extremes can undermine progress towards sustainable outcomes. The results showed that despite evidence of significant progress towards sustainable urban water management in Brisbane and Melbourne, the extreme water scarcity acted to reinforce traditional practices at the expense of emerging sustainability niches.

    A conductive activated charcoal plate (ACP) was prepared from a low-cost, abundant, and non-conductive charcoal. The prepared ACP was characterized using N{sub 2} adsorption/desorption isotherms, scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR) and X-ray diffraction (XRD). Brunauer-Emmett-Teller (BET) surface area of the charcoal and the ACP was 0.58m{sup 2} g{sup -1} and 461.67m{sup 2} g{sup -1}, respectively. The ACP was employed in textile wastewater treatment using electrosorption process. Response surface methodology (RSM) was applied to design the experiments. The decolorization efficiency of 76% at optimum conditions of voltage=450mV, pH=4, and contact time=120 min indicated that the ACP has promising potential to decolorize textile wastewater. Moreover, the results of the kinetic analyses demonstrated that wastewater treatment followed pseudo-first order kinetic model. The ACP electrode could be regenerated and reused effectively at five successive cycles of electrosorption/electrodesorption.

    A whey protein hydrolysate was prepared by incubation of reconstituted whey or a whey protein concentrate with Alcalase 0.6L. The proteolytic degradation of alpha-lactalbumin and beta-lactoglobulin initially resulted in 6-kDa and, later, 2.5-kDa degradation products, quickly followed by the appearance of multiple peptides of 1 kDa or smaller. The hydrolysate showed a steady increase in solubility and a biphasic change in foaming characteristics with decreasing peptide size. At the highest degree of hydrolysis achieved (22%), the majority of the peptides were smaller than 1 kDa and could be efficiently assimilated by the yeast Kluyveromyces marxianus growing in a defined medium.

    Rising energy costs and regulations on the efficient utilisation of energy resources force plant operators in all industrial sectors to focus on these aspects. Both in power generation as well as in thermal processes, the use of renewable sources is becoming more and more important. In this respect, especially the utilisation of biomass plays an ever-increasing role. The production of biocoal offers a solution to overcome the challenges of a wide range of different feedstock properties and to provide homogenised, biogenic fuels. The main objectives to be achieved in biocoal production are efficient drying, energy densification, bulk density maximisation and grindability optimisation. Here, the torrefaction of biomass presents a suitable and energy-efficient solution. With regard to uniform temperature distribution, temperature control, efficiency and final product quality, the multiple hearth furnace method is the preferred process of ThyssenKrupp Polysius. A double-zone multiple hearth furnace (POLTORR) permits both drying and torrefaction of wet biomasses up to 50% moisture content in one coupled unit. The main advantage of this process is the direct, safe and efficient utilisation of the volatiles released during torrefaction for the drying process by means of post-combustion, thus under favourable conditions, an almost autothermic process can be realized.

    Discussion about the new composite materials that integrate agro industrial residues for the masonry unit's production, which are directed towards its implementation in projects of affordable housing, is a subject of interest to the public and productive sector of the country. For this reason, it presents a descriptive review of primary and secondary sources, which support the project under study. The methodology consisted in finding research articles in databases supported by the scientific community, which are ordered, integrated and prioritized, creating a matrix synthesis, which condensed the objectives, type of material, studied properties and main results found. It was found that the composite materials for masonry use mainly clay or cement as matrix and as reinforcement, agro waste like paper fibers, bamboo, rice husks, among others are used. Moreover, the properties that determine its potential use are low density, stress resistance and low thermal conductivity. Comparing the results with traditional specimens as the block of clay, concrete, adobe vs. experimental models made of the compounds analyzed, favorable results were obtained in the case of integrating waste materials into its composition, optimized their properties. Thus, science and architecture converge through recognition of the properties of materials that expand the alternatives of building spaces, economic and environmentally sustainable.

    Full Text Available Among the by-products originated in the agro-industrial process of sugar cane, bagasse is one of the most relevant (Paturau, 1989. The negative influence of significant amount of pith, or parenchymatous tissue, present in sugarcane bagasse is discussed. Since this non-fibrous material does not give any desired properties in the pulp and paper, agglomerated boards and polymer productions, it is remarked the importance of its maximum removal. A brief historical review in the development of bagasse depithers and depithing systems is presented in this paper. Further results in the development of depither, named S.M. Caribe by its author, are described. The mechanical performance of first prototypes was evaluated in a test installation where vibration control values and temperatures in the upper and lower rotor bearings were monitored. For comparison it was made a vibrational analysis of other depithers that were in operation. For the technological evaluation the input capacity, the bagasse fiber quality obtained and the influence on the produced paper quality were controlled during two sugar cane crop seasons, as well. The results obtained were superior of those reached by most of depithers currently available in the market.

  16. New Progress in High-Precision and High-Resolution Seismic Exploration Technique in Coal Industry of China

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    In the past twenty years, the proportion of coal in primary-energy consumption in China is generally between 71.3% and 76.5%. The output of coal was 1.374 billion tons in 1996, and 1.21 tons in 1998, which ranked first in the world. Now coal is mined mainly with mechanization in China, which is planned to reach 80% in major State-owned coal mines in 2000 according to the planning of the government (Li et al., 1998; Tang Dejin, 1998).Compared with the USA and Australia, China has more complex coal geological structures. Based on high-resolution seismic technique in coal exploration, a new seismic technique with high-precision and high-resolution (2-D and 3-D) has been developed for the purpose of detecting small geological structures in coal mine construction and production to meet the needs of large-scale popularization of mechanized coal mining in China. The technique is low in cost and requires a relatively short period of exploration, with high precision and wide-range applications. In the middle of the 1980s, it began to be used in pre-mining coal exploration on a trial basis, and entered the peak of exploration in the 1990s, which has made significant progress in providing high-precision geological results for the construction and production of coal industry in China, and is still in the ascendant.This paper discusses some new progress and the exploration capability and application range of the technique.

    To realize the comprehensive utilization of coal-fired industrial solid wastes, a novel high-strength board was prepared from cal-cium silicate slag, fly ash, and flue gas desulfurization (FGD) gypsum. The changes in mineral phases, chemical structure, and morphology during hydration were investigated by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning electron mi-croscopy (SEM). A traditional board made from quartz and lime was prepared as a reference. The novel board not only consumes a lot of solid wastes, but also meets the strength requirement of the class-five calcium silicate board according to the Chinese Standard JC/T 564.2—2008. Microanalysis showed that hydrated calcium silicate gel (C−S−H(I)), ettringite, tobermorite, and xonotlite were successivelygenerated in the novel board by synergistic hydration of the mixed solid wastes. The board strength was improved by the formation of tobermorite and xonotlite but decreased by unhydrated quartz. It was demonstrated that quartz was not completely hydrated in the traditional board. As a re-sult, the flexural strength of the traditional board was much lower than that of the novel board.

    The development of operating scenarios is one of the key issues in the research for ITER which aims to achieve a fusion gain (Q) of ˜10, while producing 500 MW of fusion power for ≥300 s. The ITER Research plan proposes a success oriented schedule starting in hydrogen and helium, to be followed by a nuclear operation phase with a rapid development towards Q ˜ 10 in deuterium/tritium. The Integrated Operation Scenarios Topical Group of the International Tokamak Physics Activity initiates joint activities among worldwide institutions and experiments to prepare ITER operation. Plasma formation studies report robust plasma breakdown in devices with metal walls over a wide range of conditions, while other experiments use an inclined EC launch angle at plasma formation to mimic the conditions in ITER. Simulations of the plasma burn-through predict that at least 4 MW of Electron Cyclotron heating (EC) assist would be required in ITER. For H-modes at q95 ˜ 3, many experiments have demonstrated operation with scaled parameters for the ITER baseline scenario at ne/nGW ˜ 0.85. Most experiments, however, obtain stable discharges at H98(y,2) ˜ 1.0 only for βN = 2.0-2.2. For the rampup in ITER, early X-point formation is recommended, allowing auxiliary heating to reduce the flux consumption. A range of plasma inductance (li(3)) can be obtained from 0.65 to 1.0, with the lowest values obtained in H-mode operation. For the rampdown, the plasma should stay diverted maintaining H-mode together with a reduction of the elongation from 1.85 to 1.4. Simulations show that the proposed rampup and rampdown schemes developed since 2007 are compatible with the present ITER design for the poloidal field coils. At 13-15 MA and densities down to ne/nGW ˜ 0.5, long pulse operation (>1000 s) in ITER is possible at Q ˜ 5, useful to provide neutron fluence for Test Blanket Module assessments. ITER scenario preparation in hydrogen and helium requires high input power (>50 MW). H

    Mineral carbonation is one of the geological approaches for the sequestration of anthropogenic CO2 gas. Its concept is based on the natural weathering processes in which silicate minerals containing divalent cations such as Ca or Mg are carbonated to CaCO3 or MgCO3 in the reaction with CO2gas. Raw materials for the mineral carbonation have been extended to various industrial solid wastes such as steel slag, ashes, or FGD (flue gas desulfurization) gypsum which are rich in divalent cations. These materials have economic advantages when they are produced in CO2 emission sites. Flue gas desulfurization (FGD) gypsum is such a byproduct obtained in at coal-fired power plants. Recently, we carried out a research on the direct mineral carbonation of FGD gypsum for CO2sequestration. It showed high carbonation reactivity under ambient conditions and the process can be described as follows: CaSO4·2H2O + CO2(g) + 2NH4OH(aq) → CaCO3(s) + (NH4)2SO4(aq) (1) At the early stage of the process, calcium carbonate (CaCO3) exists as a dissolved ion pair during the induction period. High-purity CaCO3 could be precipitated from dissolved calcium carbonate solution extracted during the induction period. The effect of experimental parameters on pure CaCO3 was evaluated: CO2 flow rate (1-3 L/min), ammonia content (4-12%), and solid-to-liquid (S/L) ratio (5-300 g/L). FE-SEM (field-emission scanning electron microscopy) and XRD (X-ray diffraction) study revealed that the precipitated CaCO3 was round-shaped vaterite crystals. The induction time was inversely proportional to the CO2 flow rate and the yield for pure CaCO3 increased with the ammonia content. The formation efficiency for pure CaCO3 decreased with S/L (solid/liquid) ratio. It was 90% (mol/mol) when the S/L ratio was 5 g/L. However, S/L ratio didn't affect the maximum solubility limit of dissolved CaCO3.

    When direct wastewater biological treatment is unfeasible, a cost- and resource-efficient alternative to direct chemical treatment consists of combining biological treatment with a chemical pre-treatment aiming to convert the hazardous pollutants into more biodegradable compounds. Whereas the principles and advantages of sequential treatment have been demonstrated for a broad range of pollutants and process configurations, recent progresses (2011-present) in the field provide the basis for refining assessment of feasibility, costs, and environmental impacts. This paper thus reviews recent real wastewater demonstrations at pilot and full scale as well as new process configurations. It also discusses new insights on the potential impacts of microbial community dynamics on process feasibility, design and operation. Finally, it sheds light on a critical issue that has not yet been properly addressed in the field: integration requires complex and tailored optimization and, of paramount importance to full-scale application, is sensitive to uncertainty and variability in the inputs used for process design and operation. Future research is therefore critically needed to improve process control and better assess the real potential of sequential chemical-biological processes for industrial wastewater treatment.

    Following the 1976 Toxic Substances Control Act ban on their manufacture, PCBs remain an environmental threat. PCBs are known to bio-accumulate and concentrate in fatty tissues. Further complications arise from the potential for contamination of commercial mixtures with other more toxic chlorinated compounds such as polychlorinated dibenzodioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs). Until recently, only one option was available for the treatment of PCB-contaminated materials: incineration. This may prove to be more detrimental to the environment than the PCBs themselves due to the potential for formation of PCDDs. Metals have been used for the past ten years for the remediation of halogenated solvents and other contaminants in the environment; however, zero-valent metals alone do not possess the activity required to dehalogenate PCBs. Palladium has been shown to act as an excellent catalyst for the dechlorination of PCBs with active metals. This invention is a method for the production of a palladium/magnesium bimetal capable of dechlorinating PCBs using mechanical milling/mechanical alloying. Other base metals and catalysts may also be alloyed together (e.g., nickel or zinc) to create a similarly functioning catalyst system. Several bimetal catalyst systems currently can be used for processes such as hydrogen peroxide synthesis, oxidation of ethane, selective oxidation, hydrogenation, and production of syngas for further conversion to clean fuels. The processes for making these bimetal catalysts often involve vapor deposition. This technology provides an alternative to vapor deposition that may provide equally active catalysts. A hydrogenation catalyst including a base material coated with a catalytic metal is made using mechanical milling techniques. The hydrogenation catalysts are used as an excellent catalyst for the dehalogenation of contaminated compounds and the remediation of other industrial compounds. The mechanical milling technique is

Black-Right-Pointing-Pointer Modified micro-electrolysis used in cyclohexanone industry wastewater treatment. Black-Right-Pointing-Pointer This modified micro-electrolysis could avoid failure of the electrobath reactor. - Abstract: As new media, ceramic-corrosion-cell fillers (Cathode Ceramic-corrosion-cell Fillers - CCF, and Anode Ceramic-corrosion-cell Fillers - ACF) employed in electrobath were investigated for cyclohexanone industry wastewater treatment. 60.0 wt% of dried sewage sludge and 40.0 wt% of clay, 40.0 wt% of scrap iron and 60.0 wt% of clay were utilized as raw materials for the preparation of raw CCF and ACF, respectively. The raw CCF and ACF were respectively sintered at 400 Degree-Sign C for 20 min in anoxic conditions. The physical properties (bulk density, grain density and water absorption), structural and morphological characters and toxic metal leaching contents were tested. The influences of pH, hydraulic retention time (HRT) and the media height on removal of COD{sub Cr} and cyclohexanone were studied. The results showed that the bulk density and grain density of CCF and ACF were 869.0 kg m{sup -3} and 936.3 kg m{sup -3}, 1245.0 kg m{sup -3} and 1420.0 kg m{sup -3}, respectively. The contents of toxic metal (Cu, Zn, Cd, Pb, Cr, Ba, Ni and As) were all below the detection limit. When pH of 3-4, HRT of 6 h and the media height of 60 cm were applied, about 90% of COD{sub cr} and cyclohexanone were removed.

    One of the challenges for the cement industry is the quality assurance of alternative fuel (e.g., solid recovered fuel, SRF) in co-incineration plants--especially for inhomogeneous alternative fuels with large particle sizes (d95⩾100 mm), which will gain even more importance in the substitution of conventional fuels due to low production costs. Existing standards for sampling and sample preparation do not cover the challenges resulting from these kinds of materials. A possible approach to ensure quality monitoring is shown in the present contribution. For this, a specially manufactured, automated comminution and sample divider device was installed at a cement plant in Rohožnik. In order to prove its practical suitability with methods according to current standards, the sampling and sample preparation process were validated for alternative fuel with a grain size >30 mm (i.e., d95=approximately 100 mm), so-called 'Hotdisc SRF'. Therefore, series of samples were taken and analysed. A comparison of the analysis results with the yearly average values obtained through a reference investigation route showed good accordance. Further investigations during the validation process also showed that segregation or enrichment of material throughout the comminution plant does not occur. The results also demonstrate that compliance with legal standards regarding the minimum sample amount is not sufficient for inhomogeneous and coarse particle size alternative fuels. Instead, higher sample amounts after the first particle size reduction step are strongly recommended in order to gain a representative laboratory sample.

    In 2010, as part of a national sodium reduction strategy, Canada published sodium reduction benchmark targets for packaged foods; however, no evaluation of this policy has occurred. The objective was to evaluate changes in the sodium content of packaged foods, identify categories reduced in sodium, and determine the proportion meeting Health Canada's sodium reduction benchmarks. This was a cross-sectional analysis of Canadian packaged foods in 2010 and 2013 (n = 10 487 and n = 15 394, respectively). Sodium content was obtained from the Nutrition Facts table. Overall, 16.2% of food categories had significantly reduced sodium levels. The greatest shifts in the distribution of sodium within food categories occurred in imitation seafood (mean ± SD, mg/100 g; 602 ± 50 to 444 ± 81, 26.2%, p = 0.002), condiments (1309 ± 790 to 1048 ± 620, 19.9%, p = 0.005), breakfast cereals (375 ± 26 to 301 ± 242, 19.7%, p = 0.001), canned vegetables/legumes (269 ± 156 to 217 ± 180, 19.3%, p foods meeting at least 1 of the 3 phases of the sodium reduction benchmark targets slightly increased (51.4% to 58.2%) and the proportion exceeding maximum benchmark levels decreased (25.2% to 20.8%). These data provide a critical evaluation of changes in sodium levels in the Canadian food supply. Although progress in reducing sodium in packaged foods is evident, the food industry needs to continue efforts in reducing the sodium in the foods they produce.

The results showed that the bulk density and grain density of CCF and ACF were 869.0 kg m(-3) and 936.3 kg m(-3), 1245.0 kg m(-3) and 1420.0 kg m(-3), respectively. The contents of toxic metal (Cu, Zn, Cd, Pb, Cr, Ba, Ni and As) were all below the detection limit. When pH of 3-4, HRT of 6h and the media height of 60 cm were applied, about 90% of COD(cr) and cyclohexanone were removed.

  6. From Disparity to Harmonisation of Construction Industry Payment Legislation in Australia: A Proposal for a Dual Process of Adjudication based upon Size of Progress Payment Claim

    Directory of Open Access Journals (Sweden)

    Jeremy Coggins

    2011-06-01

    Full Text Available Since the introduction of the Building and Construction Industry Security of Payment Act into New South Wales in 1999, construction industry payment legislation has progressively been enacted on a jurisdiction-by-jurisdiction basis throughout Australia. Of the eight Australian Acts, two distinct legislative models can be discerned – what have been termed the ‘East Coast’ and ‘West Coast’ models. This article compares the two models with respect to their payment systems and adjudication schemes, procedural justice afforded, incursion upon freedom of contract, uptake rates and efficiency. From this comparison, the strengths and weaknesses of the two models are identified. Finally, a dual process of adjudication based on progress payment claim size is proposed for a harmonised model, developed from previous proposals put forward by other authors, which aims to combine the strengths of the two existing models.

    Reduced energy consumption and improved product attributes are realizable benefits that are achievable through the adoption of optimal metal forming techniques. With the meteoric rise in energy costs, certain segments of the metal forming industries have accelerated their efforts in switching from energy intensive manufacturing techniques, e.g., casting, to metal forming, and, furthermore, from hot forming and machined components to cold forming, notably the automotive industry. The first year results of a two year study that will identify and document potential energy and cost savings associated with the adoption of low energy consumption techniques are presented. When compared with techniques requiring energy for hot forming, heat treatments, and excess or scrap material, the utilizaton of alternative metal forming processes offer considerable promise for energy savings. Descriptions of savings achieved by a combination of analytical methods and imaginative new processes are provided in the form of specific industrial case studies. The elimination of defects through the use of an analytical criteria for the prevention of the central burst is presented. Such available criteria for central burst serve as a justification for the desirability to develop criteria for the prevention of fishskin and other defects. Other savings which may be possible through the development of new technologies are included in an Appendix entitled: Recent Developments in Wire Making. One specific new process, Continuous Hydrostatic Extrusion, has been developed at Western Electric and is described in detail.

  3. Sustainable use of industrial-waste as partial replacement of fine aggregate for preparation of concrete – A review

    Full Text Available Utilisation of industrial waste materials in concrete compensates the lack of natural resources, solving the disposal problem of waste and to find alternative technique to safeguard the nature. There are a number of industrial wastes used as fully or partial replacement of coarse aggregate or fine aggregate. This review carries out a thorough assessment about industrial waste substances, which can be adequately utilised in concrete as fine aggregate substitution. This paper reviewed some of these industrial wastes like waste foundry sand, steel slag, copper slag, imperial smelting furnace slag (ISF slag, blast furnace slag, coal bottom ash, ferrochrome slag, palm oil clinker etc. Out of these materials, maximum number of experiments have been conducted using waste foundry sand and copper slag as fine aggregate replacement, but still more examinations are required for other waste materials as replacement of sand in concrete. Different physical and mechanical properties of industrial waste as well as of industrial waste concrete, in which natural sand is substituted have been reviewed and comparisons are made between them. Deflection and leaching study review are carried out additionally and compared. It can be observed that the concrete where sand is replaced by copper slag, imperial smelting furnace slag, class F fly ash exhibits improved strength and durability properties, but it’s slump increases as the rate of replacement increases in the case of copper slag and the slump decreases in the case of class F fly ash. There is a less research work reported on ferrochrome slag and palm oil clinker used as sand substitution, so it is felt that further detailed investigations are required.

    2015-01-01

    Animal research together with other investigational methods (computer modeling, in vitro tests, etc) remains an indispensable part of the pharmaceutical research and development process. The European pharmaceutical industry recognizes the responsibilities inherent in animal research and is committed to applying and enhancing 3Rs principles. New nonsentient, ex vivo, and in vitro methods are developed every day and contribute to reducing and, in some instances, replacing in vivo studies. Their utility is however limited by the extent of our current knowledge and understanding of complex biological systems. Until validated alternative ways to model these complex interactions become available, animals remain indispensable in research and safety testing. In the interim, scientists continue to look for ways to reduce the number of animals needed to obtain valid results, refine experimental techniques to enhance animal welfare, and replace animals with other research methods whenever feasible. As research goals foster increasing cross-sector and international collaboration, momentum is growing to enhance and coordinate scientific innovation globally—beyond a single company, stakeholder group, sector, region, or country. The implementation of 3Rs strategies can be viewed as an integral part of this continuously evolving science, demonstrating the link between science and welfare, benefiting both the development of new medicines and animal welfare. This goal is one of the key objectives of the Research and Animal Welfare working group of the European Federation of Pharmaceutical Industries and Associations. PMID:25836966

    As a part of an ongoing project on the production of composite materials based on poly(vinyl alcohol) (PVA) and polymeric materials from renewable resources, the present paper reports on the incorporation of agricultural waste materials as organic fillers in a film matrix based on PVA as continuous phase. In this study lignocellulosic fibers byproducts, derived from sugar cane (SC) and apple (AP) and orange (OR) fruit juice extraction, were cast from PVA aqueous solutions. The effect of fiber type and composition on the relative properties of cast films was evaluated and compared. OR resulted to be suitable for blending in higher amounts by weight than SC and AP. Glycerol and urea were added as plasticizing agents and were observed to be effective in giving flexible films. Additionally, cornstarch was added to further increase the composition of polymers from renewable resources in cost-effective and ecoefficient composite film formulations. The prepared films resulted sensitive to moisture and water. To reduce water sensitivity, hexamethoxymethylmelamine (HMMM) was tested as a cross-linking agent for the present composite formulations. Cross-linked films exhibited significant improvement in water-resistance that can be taken as a tuneable structural feature for customized applications. The mechanical properties of the prepared composite films (elongation at break, tensile strength, Young modulus) were found to be dependent upon the nature and content of the filler and on environmental conditions.

    The addition of carbon nanotubes (CNTs) to polymeric matrices or master batches has the potential to provide composites with novel properties. However, composites with a uniform dispersion of CNTs have proved to be difficult to manufacture, especially at an industrial scale. This paper reports on processing methods that overcome problems related to the control and reproducibility of dispersions. By using a high pressure homogenizer and a three-roll calendaring mill in combination, CNT reinforced epoxies were fabricated by mould casting with a well dispersed nanofiller content from 0.1 to 2 wt%. The influence of the nano-carbon reinforcements on toughness and electrical properties of the CNT/epoxies was studied. A substantial increase of all mechanical properties already appeared at the lowest CNT content of 0.1 wt%, but further raising the nanofiller concentration only led to moderate further changes. The most significant enhancement was obtained for fracture toughness, reaching up to 82%. The low percolation thresholds were confirmed by electrical conductivity measurements on the same composites yielding a threshold value of only about 0.01 wt%. As corroborated by a thorough microscopic analysis of the composites, mechanical and electrical enhancement points to the formation of an interconnected network of agglomerated CNTs.

    Centrifugal Barrel polishing (CBP) is becoming a common R&D tool for SRF cavity preparation around the world. During the CBP process a cylindrically symmetric SRF cavity is filled with relatively cheap and environmentally friendly abrasive and sealed. The cavity is then spun around a cylindrically symmetric axis at high speeds uniformly conditioning the inner surface. This uniformity is especially relevant for SRF application because many times a single manufacturing defects limits cavity?s performance well below it?s theoretical limit. In addition CBP has created surfaces with roughness?s on the order of 10?s of nm which create a unique surface for wet chemistry or thin film deposition. CBP is now being utilized at Jefferson Laboratory, Fermi Laboratory and Cornell University in the US, Deutsches Elektronen-Synchrotron in Germany, Laboratori Nazionali di Legnaro in Italy, and Raja Ramanna Centre for Advanced Technology in India. In this talk we will present current CBP research from each lab including equipment, baseline recipes, cavity removal rates and subsequent cryogenic cavity tests on niobium as well as copper cavities where available.

    Rozelle, P.

    1996-01-01

    This report describes the progress made during this reporting period of a two year project to demonstrate that the air pollution from a traveling grate stoker being used to heat water at a central heating plant in Krakow, Poland can be reduced significantly by (1) substituting the unwashed, unsized coal currently being used with a mechanically cleaned, double-sized stoker fuel and by (2) optimizing the operating parameters of the stoker. It is anticipated that these improvements will prove to be cost effective and hence be adopted by the other central heating plants in Krakow and indeed, throughout Eastern European cities where coal continues to be the primary source of fuel. EFH Coal Company has formed a partnership with two Polish institutions -- MPEC, a central heating company in Krakow, and Naftokrak-Naftobudowa, preparation plant designers and fabricators, for the execution of this effort. The washability data from a 20mm x 0.5mm size fraction of raw coal from the Nikwa Modrejow Mine were evaluated. The data show that the ash content of this coal can be reduced from 34.0 percent to 9.0 percent by washing in a heavy-media cyclone at 1.725 sp.gr.; the actual yield of clean coal would be 63.1 percent. This product would meet compliance limitations of 500 a of SO{sub 2}/GJ. An evaluation of the predicted results that can be expected when washing five different candidate Polish coals shows that compliance products containing less than 640 a SO{sub 2}/GJ and 10 percent ash at attractive yields can be produced by washing the raw coals in a heavy-media cyclone. Discussions with financial institutions regarding the cost of producing a quality stoker coal in Poland and for identifying sources of private capital to help cost share the project continued. The search for markets for utilizing surplus production from the new plant continued.

    Digital and image analysis technologies in greenhouses have become commonplace in plant science research and started to move into the plant breeding industry. However, the core of plant breeding work takes place in fields. We will present successive technological developments that have allowed the migration and application of remote sensing approaches at large into the field of crop genetics and physiology research, with a number of projects that have taken place in France. These projects have allowed us to develop combined sensor plus vector systems, from tractor mounted and UAV (unmanned aerial vehicle) mounted spectroradiometry to autonomous vehicle mounted spectroradiometry, RGB (red-green-blue) imagery and Lidar. We have tested these systems for deciphering the genetics of complex plant improvement targets such as the robustness to nitrogen and water deficiency of wheat and maize. Our results from wheat experiments indicate that these systems can be used both to screen genetic diversity for nitrogen stress tolerance and to decipher the genetics behind this diversity. We will present our view on the next critical steps in terms of technology and data analysis that will be required to reach cost effective implementation in industrial plant breeding programs. If this can be achieved, these technologies will largely contribute to resolving the equation of increasing food supply in the resource limited world that lies ahead.

    1995-06-01

    The objective of this research is the development of improved technology for the preparation of coal-water slurries that have potential for replacing fuel oil in direct combustion. Detailed investigations of the effect of solids content and chemical additives on the rheology of coal-water slurries, prepared with fines produced by the ball milling of Pittsburgh No. 8 coal, were conducted during the first phase of the research program. These experiments were to provide a baseline against which the rheological behavior of slurries prepared with fines produced by high-pressure roll milling or hybrid high-pressure, roll mill/ball mill grinding could be compared. The viscosity of slurries with high solids content is strongly influenced by the packing density of the feed material. The packing density can be significantly altered by mixing distributions of different median sizes, and to an extent by modifying the grinding environment. The research during this quarter was, therefore, directed towards: (1) establishing the relationship between the packing characteristic of fines and the viscosity of slurries prepared with the fines; (2) investigation of the effect of mixing distribution on the rheology; and (3) study of the effect of grinding environment in the ball mill on the rheology of coal-water slurries.

    Full Text Available Chlortetracycline (CTC contamination of aquatic systems has seriously threatened the environmental and human health throughout the world. Conventional biological treatments could not effectively treat the CTC industrial wastewater and few studies have been focused on the wastewater systematic treatment. Firstly, 40.0 wt% of clay, 30.0 wt% of dewatered sewage sludge (DSS, and 30.0 wt% of scrap iron (SI were added to sinter the new media (cathode-anode integrated ceramic filler, CAICF. Subsequently, the nontoxic CAICF with rough surface and porous interior packed into ME reactor, severing as a pretreatment step, was effective in removing CTC residue and improving the wastewater biodegradability. Secondly, expanded granular sludge bed (EGSB and sequencing batch reactor (SBR, serving as the secondary biological treatment, were mainly focusing on chemical oxygen demand (COD and ammonia nitrogen (NH3-N removal. The coupled ME-EGSB-SBR system removed about 98.0% of CODcr and 95.0% of NH3-N and the final effluent met the national discharged standard (C standard of CJ 343-2010, China. Therefore, the CTC industrial wastewater could be effectively treated by the coupled ME-EGSB-SBR system, which has significant implications for a cost-efficient system in CTC industrial systematic treatment and solid wastes (DSS and SI treatment.

    The primary objective of the present Phase 3 effort is to perform the final testing at a 20 MMBtu/hr commercial scale of an air cooled, slagging coal combustor for application to industrial steam boilers and power plants. The focus of the test effort will be on combustor durability, automatic control of the combustor`s operation, and optimum environmental control of emissions inside the combustor. In connection with the latter, the goal is to achieve 0.4 lb/MMBtu of SO{sub 2} emissions, 0.2 lb/MMBtu of NO{sub x} emissions, and 0.02 lb particulates/MMBtu. Meeting the particulate goal will require the use of a baghouse or electrostatic precipitator to augment the nominal slag retention in the combustor. The NO{sub x} emission goal will require a modest improvement over maximum reduction achieved to date in the combustor to a level of 0.26 lb/MMBtu. To reach the SO{sub 2} emissions goal may require a combination of sorbent injection inside the combustor and sorbent injection inside the boiler, especially in high (>3.5%) sulfur coals. Prior to the initiation of the project, SO{sub 2} levels as low as 0.6 lb/MMBtu, equal to 81% reduction in 2% sulfur coals, were measured with boiler injection of calcium hydrate. The final objective is to define suitable commercial power or steam generating systems to which the use of the air cooled combustor offers significant technical and economic benefits. In implementing this objective both simple steam generation and combined gas turbine-steam generation systems will be considered.

    Thin SiO{sub 2} layers were deposited on the surface of porous Vycor glass by alternating vapor phase reaction with SiCl{sub 4} and H{sub 2}O. The membranes prepared by this technique had H{sub 2} permeance of 0.3--0.4 cm{sup 3} (STP)/(min{center_dot}cm{sup 2}{center_dot}atm) and H{sub 2}:N{sub 2} selectivity of 500--1000 at 600{degrees}C. The SiCl{sub 4} dosage at each silylation cycle, the concentration of initial surface -OH groups, and the reaction temperature influence significantly the deposit layer thickness- After two weeks of heating at 550{degrees}C under 3 atmospheres of water vapor, the membrane H{sub 2} permeance decreased by about 20%, and the selectivity increased to more than 2000. The membrane properties after this hydrothermal treatment are superior to those of membranes prepared earlier by one-sided (steady flow) deposition. A simple model incorporating diffusion and surface reaction was used to study the effect of various parameters on the formation of the deposit layer.

    The aim of this project is to find a feasible method for combustion of sewage sludge in existing boilers of the paper industry. Biological sludge is complicated to handle since it contains a lot of bound water. Problems arise at dehydration and subsequent treatment. Moreover, the trend is that the amount of biological sludge increases whereas the amount of easily dehydrated fibre sludge decreases. Today, mixed sludge is combusted at more then half of the paper and pulp mills in Sweden. In order to evaluate the existing problems and the characteristics of different sludge, five mills have been studied. Sludge from three of these mills has also been analysed with regards to content and combustion properties. The content of sludge from different mills varies greatly. If the ash content is high, some substances, especially the alkali metals can cause problems at combustion such as sintering and deposits in the boiler. The analysed sludge did not contain important amounts of substances that causes problems at combustion, nor any toxic substances, except from one mill that had relatively high content of mercury. The combustion tests proved that combustion and especially drying of sludge is made preferably when the sludge particles are small, on as big an area as possible. One feasible method to combust sludge from the forest industry is to dehydrate so called fibre sludge to the same dry substance content as bark, in order to introduce it with existing fuel feeding devises and combust it together with the other fuel on the grate in a grate boiler. Dehydrated biological sludge, with considerably higher moisture content than pure fibre sludge, is added with a burner devise above the bed. The sludge particles are dried (in the furnace) and combusted before they leave the furnace. In this way, wet sludge that plug the bed is avoided. The location of the sludge feeding device in the boiler is important and should be adjusted individually to each furnace. Simulations show that

  12. Recent progress in the applications of layer-by-layer assembly to the preparation of nanostructured ion-rejecting water purification membranes.

    Science.gov (United States)

    Sanyal, Oishi; Lee, Ilsoon

    2014-03-01

    Reverse osmosis (RO) and nanofiltration (NF) are the two dominant membrane separation processes responsible for ion rejection. While RO is highly efficient in removal of ions it needs a high operating pressure and offers very low selectivity between ions. Nanofiltration on the other hand has a comparatively low operating pressure and most commercial membranes offer selectivity in terms of ion rejection. However in many nanofiltration operations rejection of monovalent ions is not appreciable. Therefore a high flux high rejection membrane is needed that can be applied to water purification systems. One such alternative is the usage of polyelectrolyte multilayer membranes that are prepared by the deposition of alternately charged polyelectrolytes via layer-by-layer (LbL) assembly method. LbL is one of the most common self-assembly techniques and finds application in various areas. It has a number of tunable parameters like deposition conditions, number of bilayers deposited etc. which can be manipulated as per the type of application. This technique can be applied to make a nanothin membrane skin which gives high rejection and at the same time allow a high water flux across it. Several research groups have applied this highly versatile technique to prepare membranes that can be employed for water purification. Some of these membranes have shown better performance than the commercial nanofiltration and reverse osmosis membranes. These membranes have the potential to be applied to various different aspects of water treatment like water softening, desalination and recovery of certain ions. Besides the conventional method of LbL technique other alternative methods have also been suggested that can make the technique fast, more efficient and thereby make it more commercially acceptable.

    1997-12-31

    The increasing levels of competition that are available to commercial and residential customers of energy services, particularly in the electricity industry, were discussed. Customer choice has recently become a big issue that allows customers to sanction those companies whose performance is considered to be inadequate. Next to consumer satisfaction, Canadian companies are also looking to protect export flows and to build new opportunities by obtaining marketing licenses in the United States based on their ability to meet Federal Energy Regulatory Commission (FERC) orders 888 and 889. TransAlta Utilities in Alberta, B.C. Hydro, and Hydro-Quebec have already received FERC approval whereas Ontario Hydro has yet to meet FERC`s minimum requirements. The common elements underpinning the repositioning of utility companies were reviewed. These include: (1) the break-down of vertically integrated utilities into competitive production and retailing activities, (2) power generation as a price sensitive commodity business that favours low-cost producers, and (3) the emergence of marketers and brokers in the retail end of the business. The convergence of the gas and electricity markets as well as the electricity and telecommunications markets is another factor that will become increasingly important in the near future. This and the emergence of small-scale combined cycle gas turbines, now capable of delivering energy at prices competitive with large scale facilities, are just two examples of the impact of rapidly advancing technology.

    The preparation of a biomass conversion technology and cost data bank for the Biomass Energy Systems Branch (BES) of DOE/Solar is described. Technical and economic analyses of a number of BES technology options are currently underway. A total of 22 biomass conversion technology options (14 thermochemical and 8 biochemical) have been selected for inclusion in the data bank. These options cover the production of electric power, steam, gases, liquids, and solid fuels from biomass. The majority of the options are believed to be available now or in the near term. A consistent methodology for construction of the data bank has been developed. For each option, the most up-to-date process/product data are gathered and analyzed. A base case is established to generate estimates for plant investments required, operating cost, and product cost. The estimates are then examined systematically to identify and quantify the uncertainties. The uncertainties are combined using statistical methods to produce error band estimates. Preliminary results for catalytic liquefaction (PETC and LBL processes), gasoline from biomass (China Lake process), and MBG from wood, ethanol fermentation are reported here. A sensitivity analysis for co-generation is also reported.

This status report summarizes the work on industry outreach that has been completed since the inception of the project in October 1994. A three-pronged approach was taken to ascertain issues related to industry outreach. First, there was a review of on-going and past industry outreach activities at DOE and NHA. Next, a series of meetings with industry decision makers was arranged to get a better understanding of industry interests and concerns, and to discuss how DOE and industry could work collaboratively to develop hydrogen energy systems. Third, a workshop is scheduled where representatives from industry, DOE and other federal agencies can identify issues that would enhance partnering between the federal government and industry in the development of hydrogen energy systems. At this tiny, the review of on-going and past activities has been completed. Industry interviews are in progress and a majority of meetings have been held. Analysis of the information gained is in progress. The preliminary analysis of this information indicates that for appropriate near-term demonstration-type projects, the level of interest for collaboration between DOE and industry is high. The data also identifies issues industry is concerned with which impact the commercialization of hydrogen energy systems.

    In recent years,due to the lack of oil resources,the way of using lignocellulose to produce ethanol has attracted more and more attention. Wetland plants were considered as a research object. Using artificial wetland plants to produce fuel ethanol,not only can reduce the gas of harmful emissions,alleviate the lack of grain crops raw materials,but also can reduce the accumulation of wetland plants which could lead to secondary pollution. However,it is extremely difficult to produce ethanol directly from lignocellulose,due to the low rate of ethanol production,the expensive cellulase and the not well developed lignocellulose pretreatment process. This paper is to discuss the stain resistance and decontamination,appropriate allocation and multipurpose use of artificial wetland plants together with the existing problems when wetland plants are chosen. Key process was analyzed regarding the active ingredient of artificial wetland plants and other lignocellulose when fuel ethanol is produced via the pretreatment and hydrolysis effects of artificial wetland plants and other lignocellulose. The feasibility for the preparation of fuel ethanol from artificial wetland plants was discussed,and the future research development trend is prospected. At last,it can be concluded that wetland plants can replace grain crops fermentation to produce ethanol.%近年来,石油资源短缺,利用木质纤维素制备燃料乙醇越来越受到重视,本文以人工湿地植物为研究对象,利用人工湿地植物制备燃料乙醇,可以减少有害气体的排放、缓解粮食原材料的紧缺、减少植物处理不当产生的二次污染。但同时存在乙醇产率低、纤维素酶价格贵、木质纤维素预处理过程不成熟等问题。本文首先从人工湿地植物的抗性及去污能力、种间合理搭配及综合利用价值三方面入手,论述了在选择人工湿地植物时应注意的问题。其次重点分析了人工湿地植物及其它木

  12. Industrial Chain: Industrial Vertical Definition

    2004-01-01

    Like value chain and supply chain, “industrial chain” becomes the focus of attention. The implication of “industrial chain” has gained a large range of extension. It not only expresses the industrial “chain” structure and relationship of “back and forward”in order or “up and down” in direction, but also it represents a cluster of large scale of firms in an area or colony. It is a network, or a community. Consequently, we conclude that “industrial chain” is a synthesis of industrial chain, industrial cluster, or industrial network.In this article, firstly we will distinguish industry chain from industry. An industry is the collection of firms that have the same attribute, so an industry can be defined by firm collection of certain attribute. We indicate that industrial chain is a kind of vertical and orderly industrial link. It is defined according to a series of specific product or service created. Secondly we analyze the vertical orderly defiinition process from the aspects of social division of labor and requirement division, self-organization system, and value analysis.Non-symmetry and depending on system or community of large scale of industrial units lead to entire industry to “orderly” structure. On the other hand, the draught of diversity and complexity of requirement simultaneously lead to entire industry to be more “orderly”. Along with processes of self-organization, industrial will appi'oach the state of more orderly and steady, and constantly make industrial chain upgrade. Each firm or unit, who will gain the value, has to establish channels of value, which we called “industrial value chain”. Lastly,we discuss the consequence of vertical and orderly definition, which is exhibited by a certain relationship body. The typical forms of industrial chain include industrial cluster, strategy alliance and vertical integration etc.

It is the function of GPM to identify trends in the use of this resource and to provide a historical record of its development pathway. The information assembled for this issue of GPM indicates that trends in the use of geothermal energy in this country and abroad continue to be very positive. Favorable sentiments as well as pertinent actions on the part of both government and industry are documented in almost every section. The FEDERAL BEAT points up that the National Energy Strategy (NES) developed at the highest levels of the US government recognizes the environmental and energy security advantages of renewable energy, including geothermal, and makes a commitment to 'substantial diversification' of US sources of energy. With the announcement of the construction of several new plants and plant expansions, the INDUSTRY SCENE illustrates industry's continued expectation that the use of geothermal energy will prove profitable to investors. In DEVELOPMENT STATUS, spokesmen for both an investor-owned utility and a major geothermal developer express strong support for geothermal power, particularly emphasizing its environmental advantages. DEVELOPMENT STATUS also reports that early successes have been achieved by joint DOE/industry R & D at The Geysers which will have important impacts on the future management of this mature field. Also there is increasing interest in hot dry rock. Analyses conducted in support of the NES indicate that if all the postulated technology developments occur in this field, the price of energy derived from hot dry rock in the US could drop.

    Based on technological perspective, this paper first analyzes the effects of terms of trade movements on the benefits of industrial structure in theory, and then, classifies trade products into 5 categories by technological levels; and selects the rate of industrial technological progress and export competitiveness of high-tech industrial products as the measure of industrial structural benefits. Meanwhile, the effects are estimated for a panel of 15 countries over 1987 -2008. The results show that: the improvement of terms of trade in primary products has negative effects on industrial structural benefits, but resource-based and high-tech products have positive ones; the improvement of terms of trade in low-tech products increases the rate of technological progress, but weakens export competitiveness of high-tech industrial products; the improvement of terms of trade in medium-tech products has positive effects on industrial structural benefits in developing and newly industrializing countries, but weakens export competitiveness of high-tech industrial products in developed countries.%本文基于技术视角,将贸易产品从不同技术层级分为5类,并采取工业技术进步率和高技术工业产品出口竞争力衡量工业产业结构效益。同时,利用15个国家1987—2008年的相关数据,实证检验了不同技术层级产品贸易条件变动对工业产业结构效益的影响。结果表明:初级产品贸易条件改善对工业产业结构效益具有负效应;而资源性产品和高技术产品贸易条件改善对工业产业结构效益具有正效应;低技术产品贸易条件改善提高了工业技术进步率却削弱高技术工业产品出口竞争力;中等技术产品贸易条件改善对发展中国家及新型工业化国家工业产业结构效益具有正效应,但削弱了发达国家高技术工业产品的出口竞争力。

    @@ 1 Glass Industry and Refractories Industry Closely Connect 1.1 Glass Development Drives Refractories Progress Refractories are indispensable to glass industry; the rapid development of glass industry drives the growth of refractories industry. China's glass industry developed slowly before the mid 1980s. The kilns and furnaces were backward and small-scale with furnace life of only 2-3 years; glass was produced with extremely low efficiency and poor quality. During that period, refractories for glass melting furnaces had very limited varieties and inferior quality. The fused cast refractories for advanced glass melting furnaces were imported, for the materials made in China could not meet the requirements, which seriously restrained the technical progress of China's glass industry.

    Estimated 2012 world production of natural and synthetic industrial diamond was about 4.45 billion carats. During 2012, natural industrial diamonds were produced in at least 20 countries, and synthetic industrial diamond was produced in at least 12 countries. About 99 percent of the combined natural and synthetic global output was produced in Belarus, China, Ireland, Japan, Russia, South Africa and the United States. During 2012, China was the world’s leading producer of synthetic industrial diamond followed by the United States and Russia. In 2012, the two U.S. synthetic producers, one in Pennsylvania and the other in Ohio, had an estimated output of 103 million carats, valued at about $70.6 million. This was an estimated 43.7 million carats of synthetic diamond bort, grit, and dust and powder with a value of $14.5 million combined with an estimated 59.7 million carats of synthetic diamond stone with a value of $56.1 million. Also in 2012, nine U.S. firms manufactured polycrystalline diamond (PCD) from synthetic diamond grit and powder. The United States government does not collect or maintain data for either domestic PCD producers or domestic chemical vapor deposition (CVD) diamond producers for quantity or value of annual production. Current trade and consumption quantity data are not available for PCD or for CVD diamond. For these reasons, PCD and CVD diamond are not included in the industrial diamond quantitative data reported here.

    Full Text Available Development of accommodation, as basic services offered to tourists, led to the creation of a genuine hospitality industry. Currently, the hospitality industry is no longer just the accommodation service itself but also requires an atmosphere that ensures leisure tourists in the hotel. Thus, hospitable unit manager offers its service in addition to accommodation and catering services, leisure services, treatment services, business services required.. The existence of factors such as revenue growth, increasing leisure time, the development of transport services, the emergence of new tourist attractions have caused increasing international flows of tourists, with consequent development of units hospitable, and therefore a strong hospitality industry. In Romania, after 1990, the tourism sector experienced a true expansion, both through the development of the hotel sector, but also by developing rural hospitality units.

    Consumption of restaurant food and beverage products high in fat, sugar and sodium contribute to obesity and non-communicable diseases. We evaluated restaurant-sector progress to promote healthy food environments for Americans. We conducted a desk review of seven electronic databases (January 2006-January 2017) to examine restaurant strategies used to promote healthful options in the United States (U.S.). Evidence selection (n = 84) was guided by the LEAD principles (i.e., locate, evaluate, and assemble evidence to inform decisions) and verified by data and investigator triangulation. A marketing-mix and choice-architecture framework was used to examine eight voluntary strategies (i.e., place, profile, portion, pricing, promotion, healthy default picks, priming or prompting and proximity) to evaluate progress (i.e., no, limited, some or extensive) toward 12 performance metrics based on available published evidence. The U.S. restaurant sector has made limited progress to use pricing, profile (reformulation), healthy default picks (choices), promotion (responsible marketing) and priming and prompting (information and labeling); and some progress to reduce portions. No evidence was available to assess progress for place (ambience) and proximity (positioning) to promote healthy choices during the 10-year review period. Chain and non-chain restaurants can apply comprehensive marketing-mix and nudge strategies to promote healthy food environments for customers.

    纤维素是自然界中储量最大的天然高分子化合物,被认为是未来能源和化工的主要原料。然而,天然纤维素聚合度高、结晶度高的特性,使其难以溶于常规溶剂,极大限制了纤维素的应用。近年来,人们发现了多种新型纤维素溶剂体系,本文简要介绍了基于新型纤维素溶剂体系制备而来的再生纤维素膜以及一系列功能性再生纤维素基有机/无机复合膜材料。通过新型纤维素溶剂体系溶解再生得到的再生纤维素基复合膜在多孔性、热稳定性、强度等性能方面得到一定程度的改善,有望应用于包装、污水处理、传感器、生物医学等领域。本文基于再生纤维素膜及其复合膜材料的最新研究进展,对今后发展的热点方向进行了展望,旨在为纤维素溶解和功能性再生纤维素新材料的开发提供参考。%Cellulose, the most abundant natural renewable resources on the earth, has been considered as the main raw material for future energy and chemical industry. However, due to its high degree of polymerization and crystalline index, cellulose is extremely difficult to dissolve in conventional solvents, which greatly limits its application. More recently, many new cellulose solvents have been developed to overcome this problem. This paper briefly introduces a series of regenerated cellulose membranes and functional organic/inorganic regenerated cellulose composite membranes with these new cellulose solvents. It has been found that the properties of those cellulose composites, such as the porosity, thermal stability and mechanical properties are significantly improved, giving them promising applications in packaging, wastewater treatment, sensors, biological medicine, etc. The latest research progress of regenerated cellulose membranes and functional regenerated cellulose composites is summarized in this paper. Finally, the trends on developing cellulose solvents and

    The essay offers a selective review of central issues related to economic growth. The interrelationship between technological progress, capital accumulation, specialisation and industrial structure is emphasised. It is concluded that, first, there is little evidence that industrial structure plays an independent role in growth. Second, economists have been more successful in explaining the consequence of technological progress than the determinants of technological progress. However, even the consequences are not well understood and there is still a long way to go before general and well-documented policy implications can be drawn. (Author)

  2. Industrial Restructuring and the Selection of Pillar Industries in Qinghai Province, China

    Institute of Scientific and Technical Information of China (English)

    2010-01-01

    Based on the data from the Qinghai Statistical Yearbook 2009, the evolution course of industrial structure and the developmental status of pillar industries is analyzed. The pillar industries in Qinghai Province are analyzed and revaluated from four aspects, which cover demand and income elasticity, location quotient, contribution rate and interrelationship between industries. Through analyzing the problems and causes of the industrial structure of Qinghai Province, we know that the output structure of the three main industries has seriously departed from the employment structure; the pillar industries mainly concentrated on the fields of resource exploitation and primary processing; the interrelationship between the industries is low; and the development between the light and heavy industries are imbalanced. With the globalization and the further implementation of national preferential policies on western development, Qinghai Province follows the following principles in the restructuring of industrial structure in order to carry out the scientific thought of development and the "Ecological province" strategy. Firstly, the restructuring of industrial structure should be guided by market and scientific and technological progress. Secondly, it should fully display the regional advantages. Thirdly, it should attach importance to the developmental status and prospect of relevant accessory industries. Fourthly, the restructuring should be helpful to the labor transfer and reemployment of rural surplus labor forces. Suggestions on the selection of pillar industries and optimization of industrial structure are put forward. Qinghai Province should accelerate the restructuring of industrial structure, strengthen the support on pillar industries and lay stress on the introduction of the capitals, technologies and talents.

    energy services. As the vertically integrated industry is separated into stand-alone business, energy trading companies connect production and consumption in domestic as well as world market, with a low transaction cost due to the progress in IT technology. It should be recognized the fact that the role of energy trading companies will be becoming more and more important in the future energy market because they will directly contact consumer who will have a great market power. Pursuing sustainable development, the energy firm should prepare a appropriate plan and strategy for the paradigm shift. In doing so, the most important thing is to understand what exactly means that power shift from producers to consumers. (author). 9 refs., 7 figs., 4 tabs.

Natural resources emerge as feats of particular political and historical landscape configurations, rather than fixed dormant sediments waiting to be exploited.

    The Energy Resources Conservation Board (ERCB) has developed recommendations for a flaring and venting management framework for the province of Alberta. This report fulfilled the ERCB's information mandate regarding flaring and venting as part of a commitment made in Directive 060 for upstream petroleum industry flaring, incineration, and venting to make flaring and venting data more accessible. It included data on upstream petroleum industry flaring and venting with particular reference to solution gas conserved, flared and vented, from 1996 to 2008; solution gas flaring and venting performance; flaring from all upstream oil and gas sources, from 2000 to 2008; venting from all upstream oil and gas sources, from 2000 to 2008; solution gas flaring and venting maps; and solution gas emissions ranking of operators for 2007. The report also provided a summary of flaring and venting from various oil and gas industry sources, such as well tests, gas plants, gas gathering systems, transmission lines, and batteries. Ranking of companies was established based on solution gas flared plus vented; solution gas flared; and solution gas vented from crude oil and bitumen batteries. The data used in the preparation of this report was submitted by companies. The report revealed that considerable progress has been made in the reduction of flaring and venting volumes for all upstream oil and gas sources. The reduction can be attributed to the decline in new conventional oil production. It can also be correlated to the decline in volumes of solution gas formerly being flared, and now being vented. Solution gas vented in 2008 was 40.7 per cent less than the 2000 venting baseline. However, in 2008, there was a 25.9 per cent increase in venting from crude bitumen batteries which can be correlated to the increase in crude bitumen production. The ERCB is continuing to work with the Clean Air Strategic Alliance to examine options to further address solution gas venting. tabs., figs.

On average, economic growth has been significantly stronger in developing economies than in high-income countries, although progress cannot be observed everywhere. The financial turmoil in ASIA, the tragic events in Sudan and the conflicts in the Balkans are reminders that there is still a long way to go before the world economy is on a path of peaceful, sustainable growth. The international energy scene is characterized by increased competition on two fronts: companies and host countries. Thus the world upstream market is behaving more and more like a genuine market where the forces of supply and demand play an increasing role. 5 refs.

This report updates the progress of the PVUSA project, review the status and performance of all PV installations during 1993, and summarizes key accomplishments and conclusions for the year. The PVUSA project has five objectives designed to narrow the gap between a large utility industry that is unfamiliar with PV, and a small PV industry that is aware of a potentially large utility market but unfamiliar with how to meet its requirements. The objectives are: to evaluate the performance, reliability, and cost of promising PV modules and balance-of-system (BOS) components side-by-side at a single location; to assess PV system operation and maintenance (O and M) in a utility setting; to compare PV technologies in diverse geographic areas; to provide US utilities with hands-on experience in designing, procuring, and operating PV systems; and to document and disseminate knowledge gained from the project.

    2002-01-01

    The prospects of using electrical power beamed from space are coming closer to reality with the continued pursuit and improvements in the supporting space solar research and technology. Space Solar Power (SSP) has been explored off and on for approximately three decades as a viable alternative and clean energy source. Results produced through the more recent Space Solar Power Exploratory Research and Technology (SERT) program involving extensive participation by industry, universities, and government has provided a sound technical basis for believing that technology can be improved to the extent that SSP systems can be built, economically feasible, and successfully deployed in space. Considerable advancements have been made in conceptual designs and supporting technologies including solar power generation, wireless power transmission, power management distribution, thermal management and materials, and the integrated systems engineering assessments. Basic technologies have progressed to the point were the next logical step is to formulate and conduct sophisticated demonstrations involving prototype hardware as final proof of concepts and identify high end technology readiness levels in preparation for full scale SSP systems designs. In addition to continued technical development issues, environmental and safety issues must be addressed and appropriate actions taken to reassure the public and prepare them for the future use of this alternative renewable energy resource. Accomplishing these objectives will allow informed future decisions regarding further SSP and related R&D investments by both NASA management and prospective external partners. In particular, accomplishing these objectives will also guide further definition of SSP and related technology roadmaps including performance objectives, resources and schedules; including 'multi-purpose' applications (terrestrial markets, science, commercial development of space, and other government missions).

  14. Industrial Performance of the Renewable Resources Industry in China

    Directory of Open Access Journals (Sweden)

    Dong Zhou

    2015-08-01

    Full Text Available Promoting the development of renewable resources industry is an effective way to solve the problems of resources shortage and environmental pollution in China. In this paper, studies have found that “market structure” and “ownership structure”, namely “double structure”, is an important explanatory variable that affects industrial performance according to the “structure-conduct-performance” paradigm. Literature reviews have shown that large state-owned enterprises are playing an important role in improving the industrial performance because of the advantage in technology and capital. However, this paper analyzed the performance of China’s renewable resource industry from two aspects—the overall industrial development and the listed companies, from which two conclusions have drawn: (1 Above a designated size, private enterprises have the greatest contribution, while the contribution of state-owned and foreign-funded enterprises is different; (2 The main reason for the high positive growth rate of total factor productivity between 2009 and 2013 is the rapid growth of technological progress such as the improvement of production processes and manufacturing skills, rather than the promotion of management, system, or polices.

    Asia's population accounts for about 60% of world population, and it will grow from 3.1 billion in 1990 to 3.7 billion in 2000. Europe's population of 490 million is not expected to change significantly by 2000. The average total fertility rate (TFR) in Asia in 1991 is estimated to be 3.3. Yemen has the highest TFR (7.4). In 2010 the Asian population will number 4.19 billion, and in 2925 it will further increase to 4.97 billion. Family planning (FP) in Indonesia, Thailand, Japan, China, and in the newly industrialized economies of Hong Kong, Singapore, Taiwan, and Korea have been successful. The fertility rate has dropped to 3.0 in Indonesia and 2.2 in Thailand. The rate of growth has also diminished in India from 2.22% during 1971-82 to 2.11% during 1981-91. The Philippines has adopted the maternal child health (MCH) approach to promote FP. The Integrated Family Planning Project in China has generated a community-based FP/MCH movement by increasing the confidence of the populace especially in rural areas. The UN agencies, bilateral agencies, and international non-governmental organizations based in developed countries have provided family planning assistance in Asia. The National Family Planning Coordinating Board (BKKBN) of Indonesia is sharing its family planning experience with Bangladesh, Nigeria, and Tanzania. BKKBN also signed a memorandum of understanding on cooperation in FP with its Vietnamese counterpart in April 1992. Such technical cooperation will be more effective if UN agencies and donors from developed countries provide financial support.

    The North Okanagan Waste to Energy Consortium initiated a study that evaluated the technical, environmental and economic feasibility of a proposed biomass to renewable energy eco-system, using the technologies of anaerobic digestion (AD), cogeneration and hydroponics in a centralized waste treatment and recovery facility. The Okanagan Valley is well suited for the demonstration plant because of its concentration of food producers and processors and abundance of rich organic waste stream. The agricultural, municipal and industrial waste management consortium consisted of a dairy farm, 5 municipalities and local waste handlers. The consortium proposed to combine several organic waste streams such as dairy manure, slaughterhouse offal and source separated municipal solid waste (MSW) to produce biogas in an anaerobic digester. The methane would be processed into renewable energy (heat and electricity) for a hydroponics barley sprout operation. It is expected that the synergies resulting from this project would increase productivity, end-use efficiency and profitability. This study reviewed the basics of AD technology, technological options and evaluated several technology providers. The type and quantity of waste available in the area was determined through a waste audit and analysis. The potential to market the system by-products locally was also reviewed as well as the general economic viability of a centralized system. The study also evaluated site selection, preliminary design and costing, with reference to proximity to feedstock and markets, access to roads, impacts on neighbours and insurance of minimal environmental impact. 84 refs., 82 figs., 10 appendices.

    Examples of the merits of blue-sky research in the history of science are legion. The invention of the laser, celebrating its 50th anniversary this year, is an excellent example. When it was invented it was considered to be 'a solution waiting for a problem', and yet the level to which it has now infiltrated our day-to-day technological landscape speaks volumes. At the same time it is also true to say that the direction of research is also at times rightly influenced by the needs and concerns of the general public. Over recent years, growing concerns about the environment have had a noticeable effect on research in nanotechnology, motivating work on a range of topics from green nanomaterial synthesis [1] to high-efficiency solar cells [2] and hydrogen storage [3]. The impact of the world's energy consumption on the welfare of the planet is now an enduring and well founded concern. In the face of an instinctive reluctance to curtail habits of comfort and convenience and the appendages of culture and consumerism, research into renewable and more efficient energy sources seem an encouraging approach to alleviating an impending energy crisis. Fuel cells present one alternative to traditional combustion cells that have huge benefits in terms of the efficiency of energy conversion and the limited harmful emissions. In last week's issue of Nanotechnology, Chuan-Jian Zhong and colleagues at the State University of New York at Binghamton in the USA presented an overview of research on nanostructured catalysts in fuel cells [4]. The topical review includes insights into the interactions between nanoparticles and between nanoparticles and their substrate as well as control over the composition and nanostructure of catalysts. The review also serves to highlight how the flourishing of nanotechnology research has heralded great progress in the exploitation of catalysts with nanostructures ingeniously controlled to maximize surface area and optimize energetics for synthesis
