    As the successor of CBERS-01, CBERS-02 was launched successfully on 21October 2003 and transmitted its first downlink data the next day. According to the OBT (On Board Test) outline, CRESDA cooperated with CAST and many remote sensing organizations in China in implementing the test of the satellite payloads, ground processing system and data application. In this paper, the test is briefly illustrated in three parts: Ⅰ. Satellite Parameters Test (especially the test for payloads), Ⅱ. Payload Image Quality Assessment, and Ⅲ. Data Application Assessment. The results of the test show that the image quality of CBERS-02 is much improved over CBERS-01 and will continue to play a more important role in the society and economic development of China.

    In addition to understanding Brazilian policies and currently utilized methodologies, the measurement of the impacts of deforestation is essential for enhancing techniques to reduce deforestation in the future. Adverse impacts of deforestation include biodiversity loss, increased carbon dioxide emissions, and a reduced rate of evapotranspiration, all of which contribute directly or indirectly to global warming. With the continual growth in population in developing countries such as Brazil, increased demands are placed on infrastructural development and food production. As a result, forested areas are cleared for agricultural production. Recently, exploration for hydrocarbons in Western Brazil has also intensified as a means to stimulate the economy, as abundant oil and gas is believed to be found in these regions. Unfortunately, hydrocarbon-rich regions of Western Brazil are also home to thousands of species. Many of these regions are as of yet untapped but are at risk of ecological disruption as a result of impending human activity. This project utilized Landsat 5 TM to monitor deforestation in a subsection of the Brazilian states of Rondônia and Amazonas. A risk map identifying areas susceptible to future deforestation, based on factors such as proximity to roads, bodies of water, cities, and proposed hydrocarbon activities such as pipeline construction, was created. Areas at higher risk of clearance were recommended to be a target for enhanced monitoring and law enforcement. In addition, an importance map was created based on biodiversity and location of endangered species. This map was used to identify potential areas for future protection. A Chinese-Brazilian satellite, CBERS 2B CCD was also utilized for comparison. The NDVI model was additionally replicated in Quantum GIS, an open source software, so that local communities and policymakers could benefit without having to pay for expensive ArcGIS software. The capabilities of VIIRS were also investigated to

    China Brazil Earth Resource Satellite (CBERS) CCD images have much potential for inland water environmental monitoring. However, their atmospheric accuracy correction can affect their quantitative applications. This paper contains an atmospheric correction algorithm for CBERS CCD images with MODIS data from the same day, the use of which improves the atmospheric correction algorithm of ocean color remote sensing developed by Gordon (1993, 1994) and makes it applicable to inland waters. The improved algorithm retrieves atmospheric parameters from MODIS data and uses them to perform the atmospheric correction of CBERS CCD images. Experimental results show that the atmospheric correction algorithm of CBERS CCD images assisted by MODIS data is reliable. Furthermore, MODIS data can be freely obtained on a daily basis, making the algorithm developed in this paper useful for environmental monitoring of inland waters.

    We estimate a model of importers in Hungarian micro data and conduct counterfactual policy analysis to investigate the effect of imports on productivity. We find that importing all foreign varieties would increase firm productivity by 12 percent, almost two-fifths of which is due to imperfect substitution between foreign and domestic goods. The effectiveness of import use is higher for foreign firms and increases when a firm becomes foreign-owned. Our estimates imply that during 1993-2002 one...

    The special topography of mountain terrain will induce the retrieval distortion in same species and surface spectral lines. In order to improve the research accuracy of topographic surface characteristic, many researchers have focused on topographic correction. Topographic correction methods can be statistical-empirical model or physical model, in which the methods based on the digital elevation model data are most popular. Restricted by spatial resolution, previous model mostly corrected topographic effect based on Landsat TM image, whose spatial resolution is 30 meter that can be easily achieved from internet or calculated from digital map. Some researchers have also done topographic correction based on high spatial resolution images, such as Quickbird and Ikonos, but there is little correlative research on the topographic correction of CBERS-02B image. In this study, liao-ning mountain terrain was taken as the objective. The digital elevation model data was interpolated to 2.36 meter by 15 meter original digital elevation model one meter by one meter. The C correction, SCS+C correction, Minnaert correction and Ekstrand-r were executed to correct the topographic effect. Then the corrected results were achieved and compared. The images corrected with C correction, SCS+C correction, Minnaert correction and Ekstrand-r were compared, and the scatter diagrams between image digital number and cosine of solar incidence angel with respect to surface normal were shown. The mean value, standard variance, slope of scatter diagram, and separation factor were statistically calculated. The analysed result shows that the shadow is weakened in corrected images than the original images, and the three-dimensional affect is removed. The absolute slope of fitting lines in scatter diagram is minished. Minnaert correction method has the most effective result. These demonstrate that the former correction methods can be successfully adapted to CBERS-02B images. The DEM data can be

    Land cover classification is often based on different characteristics between their classes, but with great homogeneity within each one of them. This cover is obtained through field work or by mean of processing satellite images. Field work involves high costs; therefore, digital image processing techniques have become an important alternative to perform this task. However, in some developing countries and particularly in Casacoima municipality in Venezuela, there is a lack of geographic information systems due to the lack of updated information and high costs in software license acquisition. This research proposes a low cost methodology to develop thematic mapping of local land use and types of coverage in areas with scarce resources. Thematic mapping was developed from CBERS-2 images and spatial information available on the network using open source tools. The supervised classification method per pixel and per region was applied using different classification algorithms and comparing them among themselves. Classification method per pixel was based on Maxver algorithms (maximum likelihood) and Euclidean distance (minimum distance), while per region classification was based on the Bhattacharya algorithm. Satisfactory results were obtained from per region classification, where overall reliability of 83.93% and kappa index of 0.81% were observed. Maxver algorithm showed a reliability value of 73.36% and kappa index 0.69%, while Euclidean distance obtained values of 67.17% and 0.61% for reliability and kappa index, respectively. It was demonstrated that the proposed methodology was very useful in cartographic processing and updating, which in turn serve as a support to develop management plans and land management. Hence, open source tools showed to be an economically viable alternative not only for forestry organizations, but for the general public, allowing them to develop projects in economically depressed and/or environmentally threatened areas.

    Full Text Available The satellite images provided by remote sensors represent an important tool for monitoring, controlling and administering water resources. The aim of this work was to model the spatial distribution of the concentration of chlorhophyll-a and the limit of the photic zone in the Rio Tercero reservoir (Córdoba-Argentina, using images from CBERS-2B satellite and a geographical information system (SIG. We selected 15 samples places wherefrom we measured physical, chemical and biological parameters during the fall of 2008. By using a georeferenced image from sensor CBERS-2B and performing an analysis of the principal components (ACP, we were able to identify associations between variables and reflectance values of the satellite bands. Based on these associations and with simple regression models, we were able to know the spatial distribution of the variables: concentration of chlorophyll-a (R2 = 0, 73 and the limit of the photic zone (R2 = 0, 78 in the reservoir as a whole. We may conclude thata there exists a negative correlation between the concentration of chlorophyll-a and the water transparency in reservoir Rio Tercero, as well as that the sensor used allows us to evaluate the quality of the water in a relative short time.

    Using the data measured by energetic particle detector on board CBERS-01 and -02 for the past five years, statistics was made to show the general features of MeV electrons and protons along a solar synchronous orbit at an altitude of 780 km. This height is in the bottom region of the Earth's radiation belts. Detectors are inside the satellite cabinet and such continuous monitoring of particle radiation environment inside a satellite has seldom conducted so far. After a proper and careful treatment, it is indicated that the data inside satellite are well correlated with the radiation environment outside. Besides the agreement of the general distribution characteristics of energetic electrons and protons with similar observations from other satellites, attention is particularly paid to the disturbed conditions. Variations of particle fluxes are closely related with solar proton events, in general, electron fluxes of outer belt are well correlated with Dst index after three days' delay while the electron injection occurred almost at the same day during great magnetic storms. It is confirmed that both energetic electrons and protons appear in the Polar Cap region only after the solar proton events.

  2. STRIPING NOISE REMOVAL OF IMAGES ACQUIRED BY CBERS 2 CCD CAMERA SENSOR

    Directory of Open Access Journals (Sweden)

    E. Amraei

    2014-10-01

    Full Text Available CCD Camera is a multi-spectral sensor that is carried by CBERS 2 satellite. Imaging technique in this sensor is push broom. In images acquired by the CCD Camera, some vertical striping noise can be seen. This is due to the detectors mismatch, inter detector variability, improper calibration of detectors and low signal-to-noise ratio. These noises are more profound in images acquired from the homogeneous surfaces, which are processed at level 2. However, the existence of these noises render the interpretation of the data and extracting information from these images difficult. In this work, spatial moment matching method is proposed to modify these images. In this method, the statistical moments such as mean and standard deviation of columns in each band are used to balance the statistical specifications of the detector array to those of reference values. After the removal of the noise, some periodic diagonal stripes remain in the image where their removal by using the aforementioned method seems impossible. Therefore, to omit them, frequency domain Butterworth notch filter was applied. Finally to evaluate the results, the image statistical moments such as the mean and standard deviation were deployed. The study proves the effectiveness of the method in noise removal.

    2016-09-01

    The main biological cause of oxysterols is the oxidation of cholesterol. They differ from cholesterol by the presence of additional polar groups that are typically hydroxyl, keto, hydroperoxy, epoxy, or carboxyl moieties. Under typical conditions, oxysterol concentration is maintained at a very low and precisely regulated level, with an excess of cholesterol. Like cholesterol, many oxysterols are hydrophobic and hence confined to cell membranes. However, small chemical differences between the sterols can significantly affect how they interact with other membrane components, and this in turn can have a substantial effect on membrane properties. In this spirit, this review describes the biological importance and the roles of oxysterols in the human body. We focus primarily on the effect of oxysterols on lipid membranes, but we also consider other issues such as enzymatic and nonenzymatic synthesis processes of oxysterols as well as pathological conditions induced by oxysterols.

    Full Text Available Every spatial unit of human occupation is part of a network structuring an extensive process of urbanization in the Amazon territory. Multi-resolution remote sensing data were used to identify and map human presence and activities in the Sustainable Forest District of Cuiabá-Santarém highway (BR-163, west of Pará, Brazil. The limits of spatial units of human occupation were mapped based on digital classification of Landsat-TM5 (Thematic Mapper 5 image (30m spatial resolution. High-spatial-resolution CBERS-HRC (China-Brazil Earth Resources Satellite-High-Resolution Camera images (5 m merged with CBERS-CCD (Charge Coupled Device images (20 m were used to map spatial arrangements inside each populated unit, describing intra-urban characteristics. Fieldwork data validated and refined the classification maps that supported the categorization of the units. A total of 133 spatial units were individualized, comprising population centers as municipal seats, villages and communities, and units of human activities, such as sawmills, farmhouses, landing strips, etc. From the high-resolution analysis, 32 population centers were grouped in four categories, described according to their level of urbanization and spatial organization as: structured, recent, established and dependent on connectivity. This multi-resolution approach provided spatial information about the urbanization process and organization of the territory. It may be extended into other areas or be further used to devise a monitoring system, contributing to the discussion of public policy priorities for sustainable development in the Amazon.

  11. Are imported consumer products an important diffuse source of PFASs to the Norwegian environment?

    International Nuclear Information System (INIS)

    The aim of this study was to measure perfluoroalkyl substances in a selection of imported consumer products (n = 45) and estimate population normalized emission rates during the use phase. 6:2 and 8:2 fluorotelomer alcohol (FTOH) were found in the highest concentrations ranging from imported consumer products were estimated to be 6.6, 2130 and 197 μg year−1 capita−1 respectively for the “intermediate” emission scenario. The results from this study suggest that emissions from imported products would have a small impact on the environmental concentrations of perfluoroalkyl acids on a regional scale. - Highlights: • Per- and polyfluoroalkyl substances (PFASs) were measured in 45 imported consumer products. • Population normalized emission rates were estimated for the most abundant PFASs. • Diffuse emissions from imported consumer products constitute a minor ongoing source of PFASs. - We find no support for the hypothesis that emissions from imported consumer products would be an important ongoing source of PFASs to the environment in non-producing countries

  16. Engineered Biosynthesis of Medicinally Important Plant Natural Products in Microorganisms.

    Science.gov (United States)

    Zhang, Shuwei; Wang, Siyuan; Zhan, Jixun

    2016-01-01

    Plants produce structurally and functionally diverse natural products. Some of these compounds possess promising health-benefiting properties, such as resveratrol (antioxidant) curcumin (anti-inflammatory, anti-allergic and anticancer), paclitaxel (anticancer) and artemisinin (antimalarial). These compounds are produced through particular biosynthetic pathways in the plants. While supply of these medicinally important molecules relies on extraction from the producing species, recent years have seen significant advances in metabolic engineering of microorganisms for the production of plant natural products. Escherichia coli and Saccharomyces cerevisiae are the two most widely used heterologous hosts for expression of enzymes and reconstitution of plant natural product biosynthetic pathways. Total biosynthesis of many plant polyketide natural products such as curcumin and piceatannol in microorganisms has been achieved. While the late biosynthetic steps of more complex molecules such as paclitaxel and artemisinin remain to be understood, reconstitution of their partial biosynthetic pathways and microbial production of key intermediates have been successful. This review covers recent advances in understanding and engineering the biosynthesis of plant polyketides and terpenoids in microbial hosts. PMID:26456465

  18. Importance of aerosols for annual lightning production at global scale

    Directory of Open Access Journals (Sweden)

    S. Venevsky

    2014-02-01

    Full Text Available Lightning production is described using thermodynamic hypotheses mainly according to convective activity in the atmosphere. However, existing formal thermodynamic descriptions are unable to fully explain the profound difference in the flash rate between tropical Africa and South America and between land and ocean. Aerosols are shown to be regulators of lightning in regional studies, but their influence on lightning production at the global scale is not described. I analyzed spatial patterns of the satellite annual global flash rate and simulated, annually averaged cloud condensation nuclei (CCN distribution and found consistent positive correlation between them for land, ocean and continents. I developed a simple model of lightning production that is based solely on an aerosol hypothesis. The central premise of this model is that concentration of graupel pellets and concentration of ice crystals, which both determine flash rate, are monotonically increasing by CCN concentration up to a critical value (around 2000 cm−3. However, ice crystal concentration falls rapidly after the threshold due to lowering in the number of large cloud droplets effective for rime-splintering ice multiplication. Comparison of the model with a model of the flash rate based on thermodynamic hypotheses demonstrates that the aerosol hypothesis explains the global annual spatial distribution of lightning production consistently better over land and over oceans. My results emphasize importance of aerosols for lightning production and point to the existence of a global aerosol-lightning feedback, which affects both the climate system and the land surface.

  19. Brand importance across product categories in the Czech Republic

    2016-04-01

    Full Text Available This paper deals with customer loyalty to brands and provides an analysis of brand-related attitudes among Czech consumers. Brand loyalty is a very important aspect of competitive marketing and we contribute an empirically supported point of view on the topic. Based on primary data from a complex consumer survey carried out for the purpose of this study, we investigate the extent of brand loyalty across different product categories, mostly fast moving consumer goods (FMCG. For convenience, the analysis of our survey-data may be divided in two main areas. First, product categories are ranked according to their potential power to attract customers’ interest and loyalty towards brands. When loyalty programs are prepared, it is important to discern product categories where loyalty potential is weak from those categories that attract consumer loyalty. Second, sociodemographic features and lifestyle factors from the survey are evaluated with respect to different product categories, by means of logistic regression and subsequent average partial effect (APE analysis. A detailed and practically oriented interpretation of the empirical results is provided by the authors. However, both corporate marketers and academic readers can use the tables with empirical estimation outputs that are provided in this article to draw their own conclusions, which may be focused on the product category of interest and/or focused on any specific consumer group that is of particular interest. Among other topics, this paper emphasizes the fact that brand loyalty is a highly complex phenomenon and that it can and should be analysed from different perspectives.

  20. DEVELOPMENT OF IMPORT-SUBSTITUTING TECHNOLOGIES FOR BUILDING MATERIAL PRODUCTION

    Directory of Open Access Journals (Sweden)

    N. I. Berezovsky

    2015-01-01

    Full Text Available The paper presents results of investigations on rational usage of mineral resources. In particular, it has shown the possibility to increase a period of raw material serviceability and its application for production of building products depending on chemical and mineralogical composition of the waste. Analysis of the executed investigations shows that import substitution of anthracite, lignite and black coal for local fuels (milled peat and its sub-standard product is possible in the production technology of porous building materials.A mathematical model for drying process has been developed in the paper. Technology for thermal performance of a sintering machine with calculation of its length at the given pallet speed has been proposed on the basis of the developed model. Once-through circulation of flue gases and heated materials is the main specific feature of belt sintering machines being used in production. In such a case the whole drying process can be divided into two periods: a period of constant drying rate and a period of falling drying rate. Calculations have shown that the drying rate depends on moisture content but it does not depend on heat exchange Bio-criteria, however, heating rate is a function of temperature and Biq. A mechanism of moisture transfer using various drying methods is the same as in an environment with constant temperature and so in an environment with variable temperature. Application of the mathematical model provides the possibility to save significantly power resources expended for drying process.The paper gives description of methodology for calculation of technologically important optimum parameters for sintering processes of agglomeration while using milled peat.

  1. Remote Sensing of the EnviSat and Cbers-2B satellites rotation around the centre of mass by photometry

    Koshkin, N.; Korobeynikova, E.; Shakun, L.; Strakhova, S.; Tang, Z. H.

    2016-08-01

    During 2013-2015 the photometric observations of the EnviSat satellite, which became space debris after the failure in April 2012 in low Earth orbit, were performed. The rotation pole position and slow change in sidereal rotation period were updated on the basis of analysis of specular glints observed in 222 light curves using reduction of synodic periods. Apparently, there are minor oscillations of the rotation pole near the normal to the orbital plane. The sense of the EnviSat's spinning is opposite to the sense of its orbital rotation. The sidereal period is best approximated by the second-order polynomial: Psid (sec) = 0.000021534 ·T2 + 0.04936003 · T + 121.18195 where T is measured in days from the beginning of 2013. This method being applied to another representative of space debris, namely the Cbers-2B satellite, has shown a similar result: there is not precise solution for the rotation pole either as it undergoes oscillations with various time scale from several hours to several months. In 2014, the spin axis made the 10 ° angle with the normal to the orbital plane while the sense of spinning is direct in this case, i.e. coincides with the sense of orbital rotation. The sidereal period is best approximated by the following expression: Psid (sec) = 0.000029543 ·T2 + 0.08094931 · T + 81.31775 where T is measured in days starting from March 10, 2014. This method allows of controlling slow changes in the spatial orientation of the rotation axis of the satellites in which specular reflection of light from flat faces of the surface is inherent.

  2. Utility and importance of animal data in drug product labels.

    Baldrick, Paul

    2014-08-01

    Information on the use and safety of medicines to assist prescription by healthcare professionals occurs in drug labels (Summary of Product Characteristics in Europe and Package Insert in the USA). Animal data (notably genotoxicity, reproduction toxicity and carcinogenicity and/or repeat dose toxicity testing) comprise an important component of the information (having a vital role in giving assurance that an extensive safety assessment for the medicinal product has occurred) and regulatory guidance is available to help inform on its input into drug labels. However, an evaluation of animal data for the 27 new drugs approved in the USA in 2013 (and the same drugs if available in Europe) shows great variability in detail and level of information presented within and across regions and/or the possibility of confusion on interpretation of some of the presented animal study findings. It is concluded that it may be time to revisit what animal data are presented in drug product labels (although bearing in mind current regional regulatory guidance requirements), not only to allow within and across region consistency on information given but to present it in a way that fully assists healthcare professions when prescribing a medicine.

  4. Production and refining. Increase of Chinese petroleum imports

    International Nuclear Information System (INIS)

    China produced 156.5 Mt of petroleum in 1996, from which 56 Mt were extracted from the Daqing oil field, exploited since 1960. About 10% of the crude oil comes from offshore fields. Over the 100 Mt refined in 1996, 20 Mt were imported. The Chinese petroleum products demand should increase to 200 Mt/y by the end of the century with respect to 150 Mt/y in 1997. The Dalian refinery, the first Chinese-foreign joint venture, started to work in November 1996 and should reached its full capacity of 100000 b/day in the first quarter of 1997. The Chinese refining activity has now an excess capacity of 206 Mt/y. Several other joint venture projects in petrochemistry are planned in China. Short paper. (J.S.)

    Energy Technology Data Exchange (ETDEWEB)

    Mukhopadhyay, Aindrila; Redding, Alyssa M.; Rutherford, Becky J.; Keasling, Jay D.

    2009-12-02

    Microorganisms have been rich sources for natural products, some of which have found use as fuels, commodity chemicals, specialty chemicals, polymers, and drugs, to name a few. The recent interest in production of transportation fuels from renewable resources has catalyzed numerous research endeavors that focus on developing microbial systems for production of such natural products. Eliminating bottlenecks in microbial metabolic pathways and alleviating the stresses due to production of these chemicals are crucial in the generation of robust and efficient production hosts. The use of systems-level studies makes it possible to comprehensively understand the impact of pathway engineering within the context of the entire host metabolism, to diagnose stresses due to product synthesis, and provides the rationale to cost-effectively engineer optimal industrial microorganisms.

    2015-09-01

    Full Text Available The article proves the important role of import substitution in the economic security protection of state and its regions, especially in times of crisis, geopolitical and economical instability. The authors argue that the problem of import substitution is not modern, trendy scientific stream. The issue of displacement of import goods by domestic ones was brought up in famous classic theories of mercantilists. The particular emphasis is placed on the analysis and systematization of different scientific approaches, which are utilized by native and foreign scientists to bring out the matter of “import substitution,” to determine its essential characteristics. The authors suggest their own interpretation of the import substitution notion. In the article, the most significant pro and contra arguments in import substitution policy are defined. The regional aspects in the import substitution are approved: case study — organization of industrial import substitution in the Sverdlovsk region. In the article, the authors analyze the subject matter of the Program “Development of Intraregional Industrial Cooperation and Implementation of an Import Substitution in Branches of Industry in the Sverdlovsk Region.” It is resumed, that active policy of import substitution in the industry may become the driver of regional economic development.

    level for ecological products is indeed a decisive obstacle to the sale of ecological prducts. 2. The survey indicated that the market share for ecological products cannot be increased at the present price level. Hence, there is good reason to focus on the price parameter. 3. An experiment with price...... reductions produced considerable changes in customer choices and hence in the estimated market share. The change for tomatoes entails a doubling of the market share at a price reduction of DKK 2.00. For potatoes one could observe a 10% increase per DKK 1.30 price reduction.

  16. Prospects of petroleum product trades by ROK/Taiwan/Singapore: tougher environmental standards and changes in product imports/exports

    International Nuclear Information System (INIS)

    From April, Japan repealed the Provisional Law on Importation of Specified Petroleum Products (PLISPP) and thus freed imports further. Since the dawn of the 1990s, Asia has suffered soaring oil demand and lack of refining capacity. Besides intra-region trade, product imports from outside the region, like the US West Coast and the Mediterranean Sea, have expanded. Given such conditions in Asia, as well as Japan's stringent product specifications for environmental reasons, potential exporters of the three specified products (gasoline, kerosene and diesel) in Asia should virtually be limited to the three of the Republic of Korea (the ROK), Taiwan and Singapore. This study is designed to make an in-depth examination of the present and the future of oil supply/demand and product trade of the three countries. (author)

    Full Text Available Rice is an economically important food security crop, cultivated in almost all of Nigeria’s 36 States. Nigeria spends more than 356 billion naira (2.24 billion US dollars annually on rice import. This paper set out to analyze the trend in rice production, productivity, import, value of import and consumption that follows the adoption of the Structural Adjustment Programme (SAP in Nigeria, with emphasis on the effects of exchange rate (ER deregulation on domestic rice production and rice imports over the period 1986-2010. Relevant time series data were collected and used. A semi-log growth rate model and 2simple linear regression models were developed and estimated. Highlights of the findings include (i accelerated rate of growth in rice production (Instantaneous Growth Rate (IGR 2.2%; Cumulative Growth Rate (CGR 2.2%; rice hectarage (IGR 3.7%; CGR 3.8%; rice importation (IGR 8.5%; CGR8.9%; expenditure on rice importation (IGR 10.6%; CGR 11.2% and rice consumption (IGR 3.4%; CGR 3.5% alongside a significant deceleration in rice yield (IGR -1.4%; CGR -201.4% (ii The observed significant increase in domestic rice production cannot be confidently attributed to ER deregulation alone because it does not lead to a decrease in rice importation into Nigeria. (iii The significant increase in domestic rice importation as observed contradicts a priori expectation that ER deregulation will lead to significant decrease in rice importation. The study concluded that free market approach alone cannot stimulate local agricultural production in countries where farmers producing under low-technology-agriculture are put in direct competition with farmers from advancedtechnology-agriculture; hence governments need to restrict importation to protect local producers.

    2015-07-01

    Product development is a creative task where is systematically created a new product, which makes possible to firms to offer attractive, innovative and market oriented products. In conditions of fierce competition and saturated markets, companies that do not innovate are stagnating and disappear from the market. Innovation is therefore every intervention which can reduce production costs, enables optimum utilization of available human, energy and material resources, improve product quality, improve the placement, which leads to an increase in competitiveness. A prerequisite for fulfillment of the above-mentioned tasks is that the companies have engineers with the appropriate competencies, which are able to, through creativity, innovation and fascinating technique of creating new or improving existing products and lunch it on the market. The paper discusses the role and importance of the competences that are necessary for a successful professional career of product development engineers.

    Full Text Available Abstract With the development of technology and increasing competition, producing goods or services of the business is not enough today. Production forms of business and their pers- pectives on the environment during the production of goods and services are also monitored by the clients. Today, in the matter of ensuring the sustainability of products and hence the company, recycling has come into prominence. With these grounds, in the product life cycle costing in this study, the importance of recycling have been studied in a theoretical framework. For this purpose, basic concepts are primarily explained and product life cycle is compared with traditional costing. Then, employing the importance of recycling and its advantages are described. The presence of shortages of raw materials, the risk of extinction of natural resources and in today’s world where the cost rises, using recycled products decreases operating costs and so customers turn to recycled products with the environmental awareness. Hereat, competitiveness of enterprises, their product sales and market share have increased. In terms of environment, air and water pollution decrease and logging is prevented. During recent years, the creation of renewable resources by recycling will ensure sustainable production and bring a new dimension to the production systems.

  12. Radionuclide contents in food products from domestic and imported sources in Nigeria

    International Nuclear Information System (INIS)

    Samples of some domestic and imported food products of nutritive importance to both the child population and the adult population in Nigeria were collected and analysed in order to determine their radionuclide contents. The samples were collected from open markets in major commercial cities in the country. Gamma-ray spectrometry was employed in the determination of the radionuclide contents in the products. The gamma-ray peaks observed with reliable regularity in all the samples analysed belong to naturally occurring radionuclides, namely 226Ra, 228Th and 40K. The activity concentrations of these radionuclides in both the domestic and imported products were observed to be not significantly different. Essentially radioactive elements such as 137Cs were not detected in any of the samples. The non-detection of 137Cs in the imported products may be attributed to the suitably modified agricultural practices and countermeasures being employed to reduce caesium uptake by plants after the Chernobyl nuclear reactor accident. It seems unlikely that the elemental concentrations in the food products analysed will contribute significantly to public health risks in the country, as the cumulative ingestion effective dose values from 226Ra and 228Th were found to be low. Although 40K has the highest activity concentrations in all the samples analysed, it is usually under homeostatic control in the body, and hence the concentrations are irrelevant to possible contamination in the food products analysed.

  13. Role of the tunisian central pharmacy in the import of radio-pharmaceutical products

    International Nuclear Information System (INIS)

    In Tunisia the centralized organization of the medicine sector has a strategic and economic importance. It presents particular characteristics concerning the importation and the control of drugs. Tcp has a monopoly on the importation of drugs for the country, which enters in the state policy for the control of drug purchasing costs, their availability in different region of the country and their guarantee and quality. The Tcp has a crucial role in the availability of drugs and in the holding safety stock and strategic reserve of the imported pharmaceutical products, either for the public or private sector. The Tcp has to stock up medicaments, chemical and pharmaceutical products, objects of bandages, instruments, accessory tools and other supplies necessary for the human and veterinary medicine. The Tcp packages any specialized or not medicament and all other products or supplies. The Tcp provides medicaments and products entering within the framework of its task to different health groups and hospitals. The Tcp provides distributors, laboratories and pharmacies over the country. In Tunisia the import of radioisotopes used in the medical domain is attributed to the Tcp. The objective is to centralize purchases and to guarantee: the security, the availability as well as the traceability. The Tcp supply radiopharmaceutical products for diagnostic and therapy purposes according to an authorization delivered annually by the National Center of Radiation Protection (NCRP). An authorization of removal used at the customs allows the clearance of products at the level of the air freights by the transit service of the Tcp. Regarding the evolution of purchases of radio-pharmaceutical products, their importation remained stable during the last three years. Indeed, it is approximately around 1MDT annually (954 121 DT in 2010, 939 956 in 2011 and 1047 967 in 2012). Sources of supply are divided between 4 suppliers: International IBA-CISBIO (49.9 pour cent), COVIDIEN EX (TYCO

  14. Forecasting natural gas supply in China: Production peak and import trends

    International Nuclear Information System (INIS)

    China's natural gas consumption has increased rapidly in recent years making China a net gas importer. As a nonrenewable energy, the gas resource is exhaustible. Based on the forecast of this article, China's gas production peak is likely to approach in 2022. However, China is currently in the industrialization and urbanization stage, and its natural gas consumption will persistently increase. With China's gas production peak, China will have to face a massive expansion in gas imports. As the largest developing country, China's massive imports of gas will have an effect on the international gas market. In addition, as China's natural gas price is still controlled by the government and has remained at a low level, the massive imports of higher priced gas will exert great pressure on China's gas price reform. - Highlights: ► We figured out the natural gas production peak of China. ► We predict the import trends of natural gas of China. ► We study the international and national impacts of China's increasing import of gas. ► It is important for China to accelerate price reformation of natural gas.

  20. Evaluating the effect of exchange rate and labor productivity on import penetration of Brazilian manufacturing sectors

    Directory of Open Access Journals (Sweden)

    João Paulo Martin Faleiros

    2016-01-01

    Full Text Available In recent years, several economists have argued that the sharp loss of competitiveness of the Brazilian industry was caused by a strong exchange rate appreciation. However, other economists have attributed this loss of competitiveness to the dismal growth of labor productivity in the Brazilian industrial sector. The present paper proposes to estimate the differential impacts of variations in exchange rate and labor productivity on the Brazilian market share of imports measured by the coefficient of import penetration of total demand for manufacturing goods. We start by developing a simple theoretical model to investigate under what conditions the impacts of an exchange rate depreciation and an increase in labor productivity would differ. We test the theoretical implications of the model by means of a GMM panel data analysis focusing on 17 manufacturing sectors in the period between 1996 and 2011. Our results suggest that both variables matter to explain the coefficient of import penetration. Nevertheless, labor productivity has the strongest negative impact on the market share of imported goods, even after controlling for sector fixed-effects.

  2. Importance of core/concrete aerosol production and some containment heat sources to the source term

    International Nuclear Information System (INIS)

    Production of aerosols by core/concrete interaction in a large break PWR severe accident is discussed, and both vaporization and mechanical production processes are examined. In the case of the former, equilibrium chemical thermodynamic studies are used to decide which chemical species should be considered, recognizing the uncertainty in the likely configuration of the core/concrete melt. Lanthanide release is found to be particularly sensitive to this configuration. It is found that kinetic effects are not important in preventing the attainment of chemical equilibrium in the gas bubbling through the melt. At early times aerosol production by bubble bursting at the melt surface is found to be less important than that due to vaporization, except for those materials released in small quantities, e.g. Mo. The bubble bursting mechanism becomes relatively more important at later times. Calculations for a large modern PWR show that environmental release from the core/concrete aerosol is likely to be of comparable or greater importance (in terms of released decay heat) than that from the in-vessel core-melt aerosol for all but very early containment failure or failure to isolate, neglecting attenuation of the core/concrete aerosol during its flow from the cavity to the main containment volume. The importance of performing linked thermal-hydraulic and aerosol physics calculations is highlighted by the blowdown aerosol in a large break accident. Treatment of the decay heat arising from the aerosol material released to the containment is discussed. It is shown that it is very important to consider this heat source in containment pressure calculations, but it was not found to be important to treat its spatial dependence accurately in the large break accident considered here. Some scoping calculations for material resuspension on containment overpressure failure, due to a hydrogen burn, are presented

  3. Relative importance of nitrate and sulfate aerosol production mechanisms in urban atmospheres

    International Nuclear Information System (INIS)

    The relative importance of the various sulfate and nitrate aerosol production mechanisms is calculated for different atmospheric conditions. The calculation scheme used to determine the rates of nitrate and sulfate production, based on the concept that vapor transfer to the aerosols and nitrate and sulfate formation within the aerosols are coupled kinetic processes, considers sulfate formation by ozone and hydrogen peroxide oxidation and catalytic oxidation in the presence of soot, iron and manganese of sulfite solutions and sulfuric acid condensation and nitrate formation by the liquid-phase oxidation of dissolved nitrogen oxides for different initial gas concentrations and particle compositions and sizes. It is found that sulfate production is higher under daytime conditions, primarily proceeding by mechanisms involving sulfuric acid and hydrogen peroxide, while at night oxidation processes on the surface of the aerosol film are more important. Nitrate tends to decrease nighttime sulfate production due to an increase in aerosol acidity and nitrate production is found to be higher under nighttime conditions and in the winter

  8. Gas Strategy of China: Developing competition between national production and imports

    International Nuclear Information System (INIS)

    The Chinese gas market is facing four key challenges and the government is elaborating responses which will have implications for the Chinese and world energy markets: - Enabling the development of gas demand in order to fight against the issue of air pollution which is particularly strong in the big coast cities of the East and South-East of the country. This means replacing coal and oil by cleaner energy sources, including natural gas for which demand is booming. In such a young market, everything needs to be put in place: from the construction of LNG terminals to the sale and installation of gas stoves. The price of gas needs to be competitive for the market to develop. - Securing supplies: As national production is struggling to follow the rise in demand and as shale gas - of which China owns the second largest reserves in the world - is still a distant dream, this country is more and more reliant on imports. For evident energy security reasons, China diversifies its supplies at the maximum level and develops new energy partnerships. Four importing routes are favoured: LNG transported by ships, the West axis with Central Asia, the South axis with Burma and the new North-East axis with Russia. These imports, which amounted to 53 bcm in 2013, may triple by 2020. Even though China managed to negotiate a favourable price with Russia and its LNG importing price is lower than the one of Japan - thanks to its first LNG importing contracts signed in the early 2000 - imports are expensive, in particular for a country used to producing or importing coal at a very low cost. Up to now, the price at which gas is sold could not cover the import price and this system is not sustainable. - Developing national production: Despite important gas reserves - in particular for unconventional gas (shale gas, tight gas, CBM) - production in China is still not much developed in comparison with its potential and the growth opportunities are significant. Making the best of this potential

    Approximately 1 million tons of Agave tequilana plants are processed annually by the Mexican Tequila industry generating vast amounts of agricultural waste. The aim of this study was to investigate the potential use of Agave tequilana waste as substrate for the production of commercially important enzymes. Two strains of Aspergillus niger (CH-A-2010 and CH-A-2016), isolated from agave fields, were found to grow and propagate in submerged cultures using Agave tequilana waste as substrate. Isolates showed simultaneous extracellular inulinase, xylanase, pectinase, and cellulase activities. Aspergillus CH-A-2010 showed the highest production of inulinase activity (1.48 U/ml), whereas Aspergillus niger CH-A-2016 produced the highest xylanase (1.52 U/ml) and endo-pectinase (2.7U/ml) activities. In both cases production of enzyme activities was significantly higher on Agave tequilana waste than that observed on lemon peel and specific polymeric carbohydrates. Enzymatic hydrolysis of raw A. tequilana stems and leaves, by enzymes secreted by the isolates yielded maximum concentrations of reducing sugars of 28.2 g/l, and 9.9 g/l respectively. In conclusion, Agave tequilana waste can be utilized as substrate for the production of important biotechnological enzymes. PMID:18833660

  14. Important fission product nuclides identification method for simplified burnup chain construction

    International Nuclear Information System (INIS)

    A method of identifying important fission product (FP) nuclides which are included in a simplified burnup chain is proposed. This method utilizes adjoint nuclide number densities and contribution functions which quantify the importance of nuclide number densities to the target nuclear characteristics: number densities of specific nuclides after burnup. Numerical tests with light water reactor (LWR) fuel pin-cell problems reveal that this method successfully identifies important FP nuclides included in a simplified burnup chain, with which number densities of target nuclides after burnup are well reproduced. A simplified burnup chain consisting of 138 FP nuclides is constructed using this method, and its good performance for predictions of number densities of target nuclides and reactivity is demonstrated against LWR pin-cell problems and multi-cell problem including gadolinium-bearing fuel rod.

  15. Pharmaceuticals and personal care products alter the holobiome and development of a medically important mosquito

    International Nuclear Information System (INIS)

    The increasing demand for fresh water has forced many countries to use reclaimed wastewater for agricultural purposes. This water contains pharmaceuticals and personal care products (PPCPs) that remain biologically active following passage through wastewater treatment plants. Run-off from farms and contaminated water from treatment facilities exposes aquatic ecosystems to PPCPs. This study examined the effects of PPCPs on a lower trophic organism. Culex quinquefasciatus larvae were reared in water contaminated with environmentally relevant concentrations of common PPCPs. Acetaminophen alone and a mixture of contaminants were found to increase developmental time of larvae. Susceptibility to Bti increased in larvae exposed to antibiotics, acetaminophen, or a mixture of PPCPs. Antibiotics, hormones, and the mixture altered the mosquito bacterial microbiome. Overall, the results indicate that at environmentally relevant concentrations, PPCPs in reclaimed water can have biologically important effects on an ecologically and medically important lower trophic level insect. - Highlights: • Effects of Pharmaceuticals and Personal Care Products on mosquitoes were examined. • Three PPCP treatments increase susceptibility to a common larvicide (Bti). • Acetaminophen and the mixture of PPCPs caused an increase in developmental time. • The holobiome of mosquitoes treated with PPCPs were sequenced. • Three PPCP regimes changed the holobiome of the mosquitoes. - Pharmaceuticals and personal care products, common to reclaimed wastewater, alter the development of mosquitoes. They also alter the whole-body bacterial microbiome

  16. Importance of nuclear technology in the conservation and production of nutritional fungi

    International Nuclear Information System (INIS)

    The shortfall in food and field crops due to bad weather and the incidence of insects and microbes during harvesting, handling and storage under non-suitable conditions, called the attention of researchers to try to minimize the damage happening and by various means, whether to develop sources of new food, such as producing nutritional fungi, or by following non-traditional methods of anti-microbes and insects such as the use of radiation as a safe and successful way to save the food without any toxic effects. Permits have been issued for food irradiation by many international organizations including IAEA, World Health Organization and FAO. Nutritional fungi is one of the food sources used as food fit for human consumption in various countries around the world due to their importance which includes many aspects: the nutritional and health value; medical significance; environmental importance and industrial importance. Nuclear technology has contributed in many of the developments in the production and conservation of nutritional fungi, notably, biological studies of nutritional fungi, production technology of fungus, the role of radiation in the preparation and improvement of the nutritional media, improvement of the fungus strains, the use of radiation in the conservation of nutritional fungi and the detection of irradiated nutritional fungus.

    Full Text Available The objective of the research is to compare the importance of agribusiness in Polish and German economies. The paper analyses the internal structure of agribusiness and its share in national economies in terms of production and income results. The analysis is based on input-output matrix. The results show that the changes in the agribusiness structure in Poland go in the desired direction. The agriculture loses its significance, while food industry and industries manufacturing the production means and service become more significant. Agribusiness’ share in the national economy in Poland has been systematically falling in the analysed period. It must be emphasised here that the Polish agribusiness is still run in an old fashioned way, while in Germany it is modern. The main condition to change the situation in Poland is to generate economic growth and be able to benefit from the CAP instruments.

  19. Effect of important operating parameters on product properties and operation of HDPE slurry reactor

    International Nuclear Information System (INIS)

    In this article, a complete model for the mixed flow slurry reactor for polymerization of ethylene to high density polyethylene in the presence of Ziegler-Natta catalyst is presented. In addition to the effects of the multiple active sites, the effect of other important parameters such as the catalyst concentration, co-catalyst, hydrogen, monomer, impurities and pressure on the mass-average and number-average polymer product chain length, the average product distribution index and the required residence time for the reactor were investigated. The simulation results show that as the catalyst, hydrogen and solvent concentrations increase, the mass and number-average polymer chain length decrease, whereas with increasing monomer concentration and pressure, the average molecular weight increases. The effects of these parameters on the polydispersity index and residence time do not follow the same trend and their relationship changes in some of these variables

    The objective of this study was to determine antimicrobial resistance and elucidate the resistance mechanism in nontyphoidal Salmonella enterica serovars isolated from food products imported into the United States from 2011 to 2013. Food products contaminated with antimicrobial-resistant nontyphoidal S. enterica were mainly imported from Taiwan, Indonesia, Vietnam, and China. PCR, DNA sequencing, and plasmid analyses were used to characterize antimicrobial resistance determinants. Twentythree of 110 S. enterica isolates were resistant to various antimicrobial classes, including β-lactam, aminoglycoside, phenicol, glycopeptide, sulfonamide, trimethoprim, and/or fluoroquinolone antimicrobial agents. Twelve of the isolates were multidrug resistant strains. Antimicrobial resistance determinants blaTEM-1, blaCTX-M-9, blaOXA-1, tetA, tetB, tetD, dfrA1, dfrV, dhfrI, dhfrXII, drf17, aadA1, aadA2, aadA5, orfC, qnrS, and mutations of gyrA and parC were detected in one or more antimicrobial-resistant nontyphoidal S. enterica strains. Plasmid profiles revealed that 12 of the 23 antimicrobial-resistant strains harbored plasmids with incompatibility groups IncFIB, IncHI1, IncI1, IncN, IncW, and IncX. Epidemiologic and antimicrobial resistance monitoring data combined with molecular characterization of antimicrobial resistance determinants in Salmonella strains isolated from imported food products may provide information that can be used to establish or implement food safety programs to improve public health.

    Listeria monocytogenes, the causative organism of listeriosis, is primarily transmitted to humans through contaminated food. In this study, we examined 1275 batches of aquatic products imported from 29 countries and found that 36 batches from 8 countries were contaminated by Listeria (2.8%), with L. monocytogenes accounting for 2.6% (33/1275) and L. innocua for 0.2% (3/1275). Of the 23 selected L. monocytogenes isolates (from the 33 identified), 15 (65.2%) were of serovar 4b complex (4b, 4d, or 4e), three (13.0%) of 1/2a or 3a, four (17.4%) of 1/2b or 3b, and one (4.4%) of 1/2c or 3c. Notably, four of the 23 isolates belonged to epidemic clone I (ECI) and another four were associated with epidemic clone II (ECII), two highly clonal 4b clusters responsible for most of the documented listeriosis outbreaks. In the multilocus sequence typing scheme based on the concatenated genes gyrB-dapE-hisJ-sigB-ribC-purM-betL-gap-tuf, serovar 4b complex isolates from imported aquatic products exhibited significant genetic diversity. While the four ECI isolates were genetically related to those from Chinese diseased animals, both lacking one proline-rich repeat of ActA, the four ECII isolates were located between 1/2b or 3b strains. As the L. monocytogenes isolates from imported aquatic products possessed a nearly complete set of major infection-related genes, they demonstrated virulence potential in mouse model. PMID:19735205

  2. The Importance of Ammonia for Winter Haze Formation in Two Oil and Gas Production Regions

    Fine particle ammonium nitrate formation results from the atmospheric reaction of gaseous ammonia and nitric acid. This reaction is most important in winter when low temperatures thermodynamically enhance particle formation. Nitrogen oxides emissions from oil and gas operations partially react in the atmosphere to form nitric acid. The availability of atmospheric ammonia plays an important role in determining whether the nitric acid formed results in wintertime ammonium nitrate formation. Here we contrast situations in two important U.S. oil and gas production regions. Measurements of ammonia, nitric acid, ammonium nitrate and other species were made from 2007 to present near Boulder, Wyoming and in winters 2013 and 2014 in western North Dakota. The Boulder, Wyoming site is close to the large Jonah and Pinedale Anticline gas fields. Field sites at the north unit of Theodore Roosevelt National Park and Fort Union are situated in the large Bakken Formation oil and gas production region. Wintertime formation of nitric acid and ammonium nitrate, together comprising nitrogen in the +5 oxidation state (N(V)), was observed in both locations. Concentrations of N(V), however, are generally much lower at Boulder, WY than in the Bakken. An even bigger difference is seen in fine particle ammonium nitrate concentrations; limited regional ammonia is available in western Wyoming to react with nitric acid, leaving a portion of the nitric acid trapped in the gas phase. Higher concentrations of ammonia are observed in the Bakken where they support formation of much higher concentrations of ammonium nitrate. Comparison of these two regions clearly indicates the importance of understanding both local NOx emissions and regional concentrations of ammonia in predicting source impacts on formation of fine particles and haze.

  3. Contamination with heavy metals and bacteria in some local and imported fish and fish products

    International Nuclear Information System (INIS)

    Some local and imported fish and fish products sold in retail markets of three cities at Sharkia Governorate, Egypt, were examined against heavy metals contamination (i.e. Pb, Cd and Hg) and the presence of some specific groups of bacteria. The results showed that concentrations of Pb in fresh and frozen fish, salted and smoked fish and canned fish samples were lower than the permissible limits recommended by the Egyptian Organization 1993 (1.0 mg/kg). On the other hand, all the tested fish and fish products of collected samples showed levels of Cd (0.29-0.41 mg/kg) higher than the permissible limit (0.10 mg/kg) recommended by the Egyptian Organization. Such limits should be re-considered because the limit determined by WHO (1992) was 0.5 mg/kg. Mercury level in fresh mullet was equal or lower (0.46-0.50 mg/kg) than the limit of Egyptian Organization (0.50 mg/kg) while other fresh and frozen fish, salted and smoked fish samples had higher Hg than the allowance. In most cases, imported canned products of sardine, mackerel and tuna had higher Pb, Cd and Hg concentrations than that found in the local ones. Among fresh fish samples, such as mackarona, contained the highest total bacterial count, while mullet was the lowest. Considering salted and smoked fish, heavy salted mullet had the highest total bacterial count, while the lowest number was recorded in salted sardine. Smoked herring showed lowest total bacterial count than salted samples. Generally, no correlation was observed between fish species or consumption place and the contamination with heavy metals and bacteria

    A model to assess the value of improved information regarding the inventories, productions, exports, and imports of crop on a worldwide basis is discussed. A previously proposed model is interpreted in a stochastic control setting and the underlying assumptions of the model are revealed. In solving the stochastic optimization problem, the Markov programming approach is much more powerful and exact as compared to the dynamic programming-simulation approach of the original model. The convergence of a dual variable Markov programming algorithm is shown to be fast and efficient. A computer program for the general model of multicountry-multiperiod is developed. As an example, the case of one country-two periods is treated and the results are presented in detail. A comparison with the original model results reveals certain interesting aspects of the algorithms and the dependence of the value of information on the incremental cost function.

  8. Pesticide risk assessment in flower greenhouses in Argentina: The importance of manipulating concentrated products

    International Nuclear Information System (INIS)

    An evaluation of the Potential Dermal Exposure of workers to endosulfan and procymidone at the mix/load and application stages was done in small floricultural production units in Argentina. Seven experiments were performed with different operators under typical greenhouse conditions, based on the whole body dosimetry methodology. These results indicate that the mean Potential Dermal Exposure of the application step was 45.0 ± 55.0 mL h-1 with the highest proportion on torso, head, arms and hands. When the mix/load and application stages were compared, the first was found to contribute the most to the total exposure. Also, the Margin of Safety for the different operations was calculated, and a pesticide surrogate was developed and used to make comparative evaluations of hand exposure for different groups of operators. These results emphasize the importance of the mix/load stage in the exposure process.

  10. Remediation options and the importance of water treatment at former uranium production sites in eastern Germany

    International Nuclear Information System (INIS)

    The WISMUT remediation project in the States of Saxony and Thuringia, Germany, comprises several mine and mill sites including large volumes of production residues. Due to the climate, the intensive land use and the regulatory conditions, the water path is most important in evaluating remediation options. Water treatment is an integral part of mine flooding, mine dump and tailings remediation and treatment costs represent a major portion of the overall costs of the project. Uncertainties in the estimations of quantities of mine and seepage waters, variations in quality from site to site and changing conditions in time demand a strategic approach to the selection and optimisation of water treatment methods. The paper describes options taken and experience gained including efforts to limit long-term treatment costs by developing and applying passive treatment systems and negotiating reasonable discharge limits.

    Over the last 4 decades the use of blue water has received increasing attention in water resources research, but little attention has been paid to the quantification of green water in food production and food trade. In this paper, we estimate both the blue and green water components of consumptive water use (CWU) for a wide range of agricultural crops, including seven cereal crops, cassava, cotton, groundnuts, potatoes, pulses, rapeseed, soybeans, sugar beets, sugarcane, and sunflower, with a spatial resolution of 30 arc min on the land surface. The results show that the global CWU of these crops amounted to 3823 km3 a-1 for the period 1998-2002. More than 80% of this amount was from green water. Around 94% of the world crop-related virtual water trade has its origin in green water, which generally constitutes a low-opportunity cost of green water as opposed to blue water. High levels of net virtual water import (NVWI) generally occur in countries with low CWU on a per capita basis, where a virtual water strategy is an attractive water management option to compensate for domestic water shortage for food production. NVWI is constrained by income; low-income countries generally have a low level of NVWI. Strengthening low-income countries economically will allow them to develop a virtual water strategy to mitigate malnutrition of their people.

    To pre-establish an alternative technique to the toxic fumigant, methyl bromide which is the current quarantine measure of agricultural products for export and import, some selected agricultural products, such as chestnut, acorn, red bean and mung bean, were subjected to a preliminary study to confirm the comparative effects of gamma irradiation and MBr fumigant on their disinfestation and quality, thereby preparing the basic data for the practical approach. Current quarantine activities were examined and the related limitations were investigated. Quarantine-related pests were investigated on their radiosensitivity and disinfestation effects by both treatments. The pests in chestnut and acorn, Curculio skkimensis Heller, Curculio dentipes Roelofs, and Dichocrocis punctiferalis Guenee showed an increased mortality when exposed to above 0.5 kGy irradiation, resulting in 100% of mortality three weeks later. Callosobruchus chinensis Linne from both red and mung beans revealed a apparent mortality at around 10 days after irradiation of 1 to 3 kGy. Current fumigation was perfect in its disinfesting capability, but it caused the detrimental effects on physical quality of agricultural produce. Whereas, irradiation doses suitable for controlling the pests did not induce any significant changes in the quality of the samples. (author). 53 refs., 74 figs., 138 tabs.

  15. The importance of radon and its daughter products in environmental hygiene

    International Nuclear Information System (INIS)

    Radon and its daughter products have recently been paid great attention as components of natural ionizing radiation. Their presence in houses and flats are focus of interest. The radon isotopes and their short-lived daughter products are represented briefly, followed by a condensed survey of the historical development of this topic. There are various reasons why this became topical only 80 years after radon had been proved in the atmospheric air. After the listing of the different sources of radon, a rough risk estimation is given regarding the role of radon in lung cancer incidence in the GDR. For environmental hygiene the houses with particularly high radon content of the air, the causes of which are given, are of special importance. Among these causes the ventilation of rooms is the factor having the greatest influence on the radon concentration. From the evidence of occasional, extremely high radon values efforts are derived to elaborate limits of radon concentrations in flats. Finally, the priority of the radon problem for environmental hygiene is pointed out by indicating the current interest of this problem in literature and at congresses. (author)

  16. Micro-bubbles in cold production of heavy oil : are they present, are they important?

    2006-07-01

    Various models and studies of non-equilibrium behaviour of gas in the cold production of heavy oil have led researchers to believe that some of the geo-mechanical effects manifested in sand production are responsible for the generation of wormholes that act as high permeability conduits. This abstract examined the existence and flow of micro-bubbles and their importance in heavy oil recovery. An inline densitometer was installed on a flow-line to measure the bulk density of the fluids as they exited the porous medium. Micro-bubble flow was investigated by measuring the density of the flowing fluids. Results indicated that when micro-bubbles were present, they flowed with the oil after the bubbles were nucleated, thereby affecting the bulk density of the flowing fluid. The density of the produced fluid then decreased as a result of the existence of the micro-bubbles in the oil. In the absence of micro-bubbles, the bubbles grew in-situ and were trapped in the porous media by capillary forces. In this scenario, the flowing fluid was oil and the density measurements were not affected until the bulk gas flow started after critical gas saturation. Results of depletion experiments performed at varying depletion rates were presented, and the implications of the study for the modelling of foamy oil flow were also discussed.

  17. A preliminary investigation of radiation level and some radionuclides in imported food and food products

    International Nuclear Information System (INIS)

    A preliminary study of gross beta activity and content of some long-lived radionuclides associated with fission products in various types of imported food and food-products was carried out. Food samples were purchased monthly during 1976-1977 from general well-known supermarkets and local grocery stores up to a total of 89 samples. The gamma spectrum of long-lived radionuclides was searched using a 128 channel analyzer coupled with 3'' x 3'' NaI (T1) crystal detector. Two radionuclides were frequently found to be present in these food samples, viz. potassium-40 and cesium-137 and their concentrations were subsequently determined. The limits of detection under the conditions used for potassium-40 and cesium-137 were 0.04 and 0.03 pCi/g-wet weight, respectively. Samples were dry-ashed and counted for gross beta activity utilizing a low background anti-coincidence G.M. counter. The content of strontium-90 was also investigated concurrently by solvent extraction technique employing tri-n-butyl phosphate as an extractant. Results of the study are tabulated. (author)

  18. The socio-economic importance of family poultry production in the Republic of Mauritius

    International Nuclear Information System (INIS)

    Almost every household keeps semi-scavenging family poultry in the backyard as a tradition, both for food and for the generation of additional income in Rodrigues, the second biggest island of the Republic of Mauritius. Recent studies have shown that improving husbandry and management practices on the farm can increase the return of the family poultry farmer significantly. A survey was carried out on households with family poultry on the social and economic importance of family poultry production on the island in 2002. Results showed that on an average, the family poultry farmer was 50 years of age, 42% were illiterate, 32% of the farmers were women, and the family consisted of five members. Besides their main occupation, animal farming was the main side-activity of 56% of the households. 50% of the respondents reared chickens firstly for income, 43% for home consumption, 4% for cultural reasons, and 3% simply for leisure. The profit obtained from the sale of chickens and eggs, and the monetary value of sale and home consumption of these commodities represented 9% and 18% of the total income of the family, respectively. 65% of the households wished to expand family poultry production as they found this system of production more profitable than the rearing improved commercial broilers and layers. The birds of 5% of the farmers constituted a nuisance to their neighbours. All the poultry merchants who marketed the family poultry found their business profitable, and wished to expand it. They priced the birds by their appearance, offered US dollar 2 / kg live weight, and sold them at US dollar 3.4 / kg live-weight to consumers in Mauritius. Family poultry had a guaranteed market, especially for being free scavenging birds, and for their rustic taste. (author)

    Full Text Available Wheat is the second most cultivated crop on the world and is very important plant for feed not only mankind but also animals. Because of this is necessary to develop new varieties with better properties. Bread making quality of wheat grain is one of the most important paramaters for quality evaluation. Sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE of wheat storage proteins and allelic specific polymerase chain reaction (AS-PCR are analysis suitable for identification, differentiation and characterization of bread wheat (Triticum aestivum L.. There were analysed 16 genotypes of new varieties of bread wheat in our work by SDS-PAGE and obtained results were verified by AS-PCR. Analysed genotypes of bread wheat genotypes were homogenous and single line with very good bread making quality. Our results confirmed hypothesis, that cultivated bread wheat genotypes are uniformed with high production and quality but there is a risk of sensitivity to environmental conditions. SDS-PAGE analyses of wheat grain proteins are fast and not very expensive technique, which provide us information of bread making quality of grains. However, there is possibility of environmental influence on protein synthesis and because of this is necessary to couple these analysis with analysis of DNA.

  1. From seed production to seedling establishment: Important steps in an invasive process

    Ferreras, Ana Elisa; Galetto, Leonardo

    2010-03-01

    It is widely accepted that exotic invasive species are one of the most important ecological and economic problems. Reproductive and establishment traits are considered key features of a population expansion process, but few works have studied many of these simultaneously. This work examines how large the differences are in reproductive and establishment traits between two Fabaceae, the exotic invasive, Gleditsia triacanthos and the native, Acacia aroma. Gleditsia is a serious leguminous woody invader in various parts of the world and Acacia is a common native tree of Argentina. Both species have similar dispersal mechanisms and their reproductive phenology overlaps. We chose 17 plants of each species in a continuous forest of the Chaco Serrano Forest of Córdoba, Argentina. In each plant we measured fruit production, fruit removal (exclusion experiments), seed predation (pre- and post-dispersal), seed germination, seed bank (on each focal tree, three sampling periods during the year), and density of seedlings (around focal individuals and randomly in the study site). Gleditsia presented some traits that could favour the invasion process, such as a higher number of seeds per plant, percentage of scarified seed germination and density of seedlings around the focal individuals, than Acacia. On the other hand, Gleditsia presented a higher percentage of seed predation. The seed bank was persistent in both species and no differences were observed in fruit removal. This work highlights the importance of simultaneously studying reproductive and establishment variables involved in the spreading of an exotic invasive species. It also gives important insight into the variables to be considered when planning management strategies. The results are discussed from the perspective of some remarkable hypotheses on invasive species and may contribute to rethinking some aspects of the theory on invasive species.

  2. Uranium mining and production: A legal perspective on regulating an important resource

    International Nuclear Information System (INIS)

    The importance of uranium can be examined from several perspectives. First, natural uranium is a strategic energy resource because it is a key ingredient for the generation of nuclear power and, therefore, it can affect the energy security of a state. Second, natural uranium is also a raw material in relative abundance throughout the world, which can, through certain steps, be transformed into nuclear explosive devices. Thus, there is both an interest in the trade of uranium resources and a need for their regulatory control. The importance of uranium to the worldwide civilian nuclear industry means that its extraction and processing - the so-called 'front end' of the nuclear fuel cycle - is of regulatory interest. Like 'ordinary' metal mining, which is generally regulated within a country, uranium mining must also be considered from the more particular perspective of regulation and control, as part of the international nuclear law regime that is applied to the entire nuclear fuel cycle. The present overview of the regulatory role in overseeing and controlling uranium mining and production will outline the regulation of this resource from an international level, both from early days to the present day. Uranium mining is not regulated internationally; rather, it is a state responsibility. However, developments at the international level have, over time, led to better national regulation. One can note several changes in the approach to the uranium industry since the time that uranium was first mined on a significant scale, so that today the mining and trade of uranium is a well-established and regulated industry much less marked by secrecy and Cold War sentiment. At the same time, it is informed by international standards and conventions, proliferation concerns and a modern regard for environmental protection and the health and safety of workers and the public.

  3. Minireview: importance of herbicide-tolerant sunflower hybrids in suppressing common ragweed (Ambrosia artemisiifolia pollen production

    Directory of Open Access Journals (Sweden)

    Peter Reisinger

    2014-01-01

    Full Text Available Common ragweed (Ambrosia artemisiifolia is the number one weed in Hungary: it covers ca. 5% of the arable land, causing huge losses in row crops, especially in sunflowers. In addition, because of the high allergenicity of its pollen, common ragweed is a heavy burden on the health care system. This minireview discusses the importance of use of herbicide-tolerant sunflower hybrids in eliminating common ragweed from sunflower fields, with special emphasis on the efficacy of common ragweed control of two acetolactate-synthase inhibitor postemergence herbicides (imazamox and tribenuron methyl in several sunflower hybrids that carry the resistance gene against such herbicides. Common ragweed control by these herbicides was excellent: they suppressed the growth of the weed plant until the canopy closure of the crop (8-leaf stage. Common ragweed plants germinating after this date were unable to compete with the crop: although they survived, they remained small (ca. 70% reduction in height, produced ca. 90% less male inflorescences (source of the allergenic pollen, and caused no significant reduction in the crop yield. In order to stop the seed production by the few late-germinating weed plants we recommend a mechanical common measure (row-cultivator in late August.

  4. Importance of the Computed Tomography Dose Index (CTDI) and Dose Length Product (DLP)

    International Nuclear Information System (INIS)

    This work is under the auspice of the International Atomic Energy Agency (IAEA) projects (RAF/9/053) untitled Strengthening of the technical capacity for the protection patients and worker. The goal of this work is to highlight the importance of the Computed Tomography Dose Index (CTDI) and the Dose Length product (DLP). Measures were done at Polyclinic of Ilafy and CRDT Anosivavaka, Antananarivo, Madagascar. Doses were evaluated by use of pencil ionization chamber model 6000-10 connected with an electrometer RAD-CHECK model 06-256. Knowledge of dose indicator and Diagnostic Reference Level (DRL) allow the monitoring of scanner within the appropriate average dosimeter. It also insures the progressive determination for the most adapted dose requirements by choice of parameters available on scanner device. Measurements confirmed that doses from scanner devices of the two centers were under DRL requirements proposed by the IAEA, the European Commission (EC) and the National Radiological Protection Board (NRPB). The present results confirm that the patient delivered doses for the two centers are optimized.

  5. Modeling the importance of biomass qualities in biomass supply chains for bioenergy production

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available A tactical-operational level quantitative model can be an important decision support tool for bioenergy producers. Goal programming approach can help analyze the costs and volume implications of various competing goals in terms of biomass characteristics on part of the bioenergy producers. One cost and six quality characteristics goals, namely moisture and ash contents, and thermal values of two types of biomass (forest harvest residue and un/under-utilized species are selected for the four bioenergy producers in northwestern, Ontario, Canada. We run four models cenarios: i benchmark total cost and ceilings of mean values of six biomass qualities (Initial Goals, iirelaxing the quality goals by 10% from the Initial Goals scenario, iii increasing the conversion efficiency by 10%, and iv all goals as in Initial Goals except the Atikokan Generating Station (AGSbeing supplied with only un/under-utilized biomass. The smaller power plants have relatively less per unit biomass procurement cost. While per unit procurement costs increased, the total costs and biomass volume required to produce the same amount of bioenergy for each power plant decreased in all scenarios compared to the benchmark costs. The goal programming approach, and the results thereof are found to be useful in making effective decisions in the biomass supply chains for bioenergy production.

    Full Text Available Forage pea (Pisum sativum L. is gaining importance as a forage legume in the Republic of Croatia. Pea seed contains 20-30 percent of protein, it is utilized without thermal treatment in feeding different types and categories of livestock, and with stable yield it provides an appreciable income per hectare. Two-year field trials (2005-2006 were carried out to determine the effect of winter pea seed inoculation and nitrogen top-dressing on the number and mass (g/plant-1 of root nodules and also on the yield and quality of winter pea cv. Maksimirski rani in a mixture with wheat cv. Sana. Just before sowing, pea seeds were inoculated with the strain Rhizobium leguminosarum bv. viciae 1001 from the microbial collection of the Department of Microbiology, Faculty of Agriculture, University of Zagreb. The highest number of root nodules (43 nodules/plant, as well as the highest nodule mass (0.219 g/plant-1 were determined in the inoculated variant. The highest number of pods (19.0 and seeds per plant (60 were determined in the inoculated variant as well. The highest 1000-seed mass (132 g and seed mass per plant (7.93 g were also determined in the inoculated variant. Average pea seed yield ranged from 2949 kg ha-1 (control up to 3353 kg ha-1 (inoculation. The conclusion of this research is that the highest seed (3353 kg ha-1 and crude protein yields (833 kg ha-1 were obtained with inoculated forage winter pea cv. Maksimirski rani. Seed inoculation of the studied pea cultivar Maksimirski rani with the strain Rhizobium leguminosarum bv. viciae 1001 influenced also higher milk production per hectare compared to the control and the nitrogen top-dressed variant.

    Full Text Available The slaughter data of the National pig database was analysed by the authors. The authors investigated the results of the (SEUROP grade scheme, which showed the connection between the pig proportions fell into the various grade classes and their prices. The analyses started when the introduction of the (SEUROP grade scheme took place in 1997 and was based on the official database published each week. For the sake of better overview the results were summed up to monthly intervals. The authors found that in the first period (shortly after the introduction of the grade scheme the prices of the slaughtered pigs fell into the various grade classes differed from each other by 6-7 %. As a result of the (SEUROP grade scheme’s introduction the proportion of the slaughtered pigs fell in the grade classes E and U increased from 18% to 27% and from 37% to 44% respectively. The proportions in the R, O, and P classes consequently decreased. Following the first period no changing pattern was found concerning these proportions which means that the improvement of the graded slaughter pigs stopped. Investigating the possible explanations the authors realised that the price differences between the grade classes decreased from 6-7% to 4-5%. Thus the meat processing industry in fact was paying more for one unit lean content of slaughtered pigs when fell into the worst categories than for those which can be found in the best categories. This however does not provide any motivation for the producers for improving carcass quality, which can only be obtained through higher costs. It can be concluded that carcass quality improvement is an important requirement for Hungary. Concerning the EU members the graded slaughter pigs can be found in the E and U categories almost exclusively. The same ratio is only 65% in Hungary. Therefore the modification of slaughtered pig prices of the E and U grade classes is vital in order to motivate the production of slaughtered pigs

    Economical production of xylanase and three cellulases, endo-β-1,4-glucanase (CMCase), exo-β-1,4-glucanase (FPase), β-glucosidase (BGL) was studied in submerged fermentation using cane molasses medium. A statistical optimization approach involving Plackett-Burman design and response surface methodology (RSM) resulted in the production of 72,410, 36,420, 32,420 and 5180 U/l of xylanase, CMCase, FPase and β-glucosidase, respectively. Optimization resulted in more than fourfold improvements in production of xylanolytic and cellulolytic enzymes. Scale up of enzymes production in shake flasks of varied volumes was sustainable, suggesting a good scope for large scale enzyme production. Addition of microparticles engineered fungal morphology and enhanced enzymes production. Xylanase of S. thermophile is a neutral xylanase displaying its optimal activity at 60 °C while all the cellulases are optimally active at pH 5.0 and 60 °C. The efficacy of enzyme cocktail in waste tea cup paper and rice straw hydrolysis showed that maximum sugar yield of 578.12 and 421.79 mg/g substrate for waste tea cup and rice straw, respectively, were achieved after 24 h. Therefore, concomitant production of cellulolytic and xylanolytic enzymes will be beneficial for the saccharification of lignocellulosics in generating both monomeric and oligomeric sugars for biofuels and other biotechnological applications.

    2016-04-01

    Bumble bee (Bombus) species are ecologically and economically important pollinators, and many species are in decline. In this article, we develop a mechanistic model to analyse growth trajectories of Bombus vosnesenskii colonies in relation to floral resources and land use. Queen production increased with floral resources and was higher in semi-natural areas than on conventional farms. However, the most important parameter for queen production was the colony growth rate per flower, as opposed to the average number of available flowers. This result indicates the importance of understanding mechanisms of colony growth, in order to predict queen production and enhance bumble bee population viability. Our work highlights the importance of interpreting bumble bee conservation efforts in the context of overall population dynamics and provides a framework for doing so. PMID:26913696

    The aim of this study was to review the current legislation and rules in Brazil that involve quality assurance of animal products during food service reception. Published federal legislation and technical regulations were verified to present a broad general approach to raw material reception. Food service determinations included specifications of the criteria for evaluating and selecting suppliers, verifying the transport system, reception area requirements, and inspecting raw material. For product approval, the packaging, labeling, and temperature should be evaluated. However, periodic microbiological, physicochemical, and sensory support assessment analyses are not required for receiving animal products. For the safety of the raw material, it was concluded that the largest impacts came from the regulation and supervision of the food sector provider because of the challenges of food service and a lack of requirements to use more complex evaluation methods during the reception of raw materials.

    Today, the act of purchase is more and more irrational. Customers' choices are based on emotional and multisensorial features, particularly on touch, which is the most emotional sense. Then it is essential in the design process to work on shapes, materials, textures to make users living pleasant experiences in all contact areas of the product. It's also essential to consider the dynamic aspect of touch to follow the body and generate pleasant tactile effects. Finally, how can we introduce touch in the design process considering companies' know-how, culture and subjectivity of each actor of new product creation?

    Burd, Brenda J.; Thomson, Richard E.

    2015-11-01

    The purpose of this study is to show that seafloor hydrothermal venting in the open northeast Pacific Ocean has a marked impact on secondary biomass and production within the overlying water column. Specifically, we use net tows and concurrently measured acoustic backscatter data collected over six summers to examine the effects of hydrothermal venting from the Endeavour Segment of Juan de Fuca Ridge on macro-zooplankton biomass and production throughout the entire 2000 m depth range. Previous research shows that ontogenetic diapausing migrators and their predators from the upper ocean aggregate above the neutrally buoyant plumes in summer and resume feeding on plume and bottom upwelled particles, resulting in increased zooplankton reproductive output to the upper ocean. Within the limitations of our sampling methodology, net tows reveal a statistically significant exponential decline in total water-column biomass with increasing lateral distance from the vent fields. The acoustic backscatter data show a similar decline, but only below 800 m depth. Near-surface biomass was highly variable throughout the region, but values near vents consistently ranged higher than summer values found elsewhere in the offshore northeast Pacific. Water-column biomass was similar in magnitude above and below 800 m depth throughout the region. Because epiplume biomass can be advected a considerable distance from vent fields, biomass enhancement of the water column from hydrothermal venting may extend considerable distances to the west and northwest of the vent sites, in the prevailing directions of the subsurface flow. Based on the extensive acoustic Doppler current profiler (ADCP) data collected, and the strong correlation between zooplankton production derived from net sample biomass and acoustic backscatter intensity, we estimate that daily macro-zooplankton production in the upper 400 m of the water column within 10 km of the vent fields averages approximately 16% of photosynthetic

    2016-03-01

    The American Herbal Products Association estimates that there as many as 3000 plant species in commerce. The FDA estimates that there are about 85,000 dietary supplement products in the marketplace. The pace of product innovation far exceeds that of analytical methods development and validation, with new ingredients, matrixes, and combinations resulting in an analytical community that has been unable to keep up. This has led to a lack of validated analytical methods for dietary supplements and to inappropriate method selection where methods do exist. Only after rigorous validation procedures to ensure that methods are fit for purpose should they be used in a routine setting to verify product authenticity and quality. By following systematic procedures and establishing performance requirements for analytical methods before method development and validation, methods can be developed that are both valid and fit for purpose. This review summarizes advances in method selection, development, and validation regarding herbal supplement analysis and provides several documented examples of inappropriate method selection and application.

    2013-01-01

    Full Text Available How to seek the important nodes of complex networks in product research and development (R&D team is particularly important for companies engaged in creativity and innovation. The previous literature mainly uses several single indicators to assess the node importance; this paper proposes a multiple attribute decision making model to tentatively solve these problems. Firstly, choose eight indicators as the evaluation criteria, four from centralization of complex networks: degree centrality, betweenness centrality, closeness centrality, and eigenvector centrality and four from structural holes of complex networks: effective size, efficiency, constraint, and hierarchy. Then, use fuzzy analytic hierarchy process (AHP to obtain the weights of these indicators and use technique for order preference by similarity to an ideal solution (TOPSIS to assess the importance degree of each node of complex networks. Finally, taking a product R&D team of a game software company as a research example, test the effectiveness, operability, and efficiency of the method we established.

  8. The importance of urea-molasses multinutrient blocks for ruminant production in Indonesia

    International Nuclear Information System (INIS)

    Early work demonstrated that the growth of rumen microbes in ruminants fed cut and carry grass was low and inefficient but that with supplementation of a mixture of nutrients this improved threefold. Feeding urea-molasses multinutrient blocks (UMMBs) to buffaloes fed cut and carry grass improved rumen ammonia levels and microbial growth yield. Supplementation with UMMBs markedly stimulated milk yield and growth rate of cattle under village management conditions where other nitrogenous supplements were not used but had no effect when a large amount of concentrate or soybean curd waste was included in the diets. When supplemented with UMMBs, cattle or sheep fed cut and carry grass showed a wide variation in growth rate improvement. The best response in sheep was a 126% increase in the live weight gain of Garut fighting sheep, for which the weight gain improved from 140 g/d in the controls to 316 g/d in the supplemented lambs. Reproductive rate, specifically birth weight and survival of goats, was increased by feeding UMMBs in the traditional system of raising goats. In 12 out of 14 trials highly significant and economic increases in production resulting from feeding UMMBs were observed. The potential of UMMBs to increase both the level and efficiency of livestock production and so profitability in Indonesia is substantial and represents a major technology breakthrough for all meat/milk production systems.

  9. Photon Production through Multi-step Processes Important in Nuclear Fluorescence Experiments

    Energy Technology Data Exchange (ETDEWEB)

    Hagmann, C; Pruet, J

    2006-10-26

    The authors present calculations describing the production of photons through multi-step processes occurring when a beam of gamma rays interacts with a macroscopic material. These processes involve the creation of energetic electrons through Compton scattering, photo-absorption and pair production, the subsequent scattering of these electrons, and the creation of energetic photons occurring as these electrons are slowed through Bremsstrahlung emission. Unlike single Compton collisions, during which an energetic photon that is scattered through a large angle loses most of its energy, these multi-step processes result in a sizable flux of energetic photons traveling at large angles relative to an incident photon beam. These multi-step processes are also a key background in experiments that measure nuclear resonance fluorescence by shining photons on a thin foil and observing the spectrum of back-scattered photons. Effective cross sections describing the production of backscattered photons are presented in a tabular form that allows simple estimates of backgrounds expected in a variety of experiments. Incident photons with energies between 0.5 MeV and 8 MeV are considered. These calculations of effective cross sections may be useful for those designing NRF experiments or systems that detect specific isotopes in well-shielded environments through observation of resonance fluorescence.

    2010-07-01

    The thermal decomposition reactions of several important natural flavor and fragrance chemicals have been investigated using density functional theory (DFT, B3LYP/6-31G*). Retro-aldol reactions of glucose, fructose, hernandulcin, epihernandulcin, [3]-gingerol, and [4]-isogingerol; retro-carbonyl-ene reactions of isopulegol, lavandulol, isolyratol, and indicumenone; and pyrolytic syn elimination reactions of linalyl acetate, alpha-terpinyl acetate, and bornyl acetate, have been carried out. The calculations indicate activation enthalpies of around 30 kcal/mol for the retro-aldol reactions and for retro-carbonyl-ene reactions, comparable to pericyclic reactions such as the Cope rearrangement and electrocyclic reactions, and therefore important reactions at elevated temperatures (e.g., boiling aqueous solutions, gas-chromatograph injection ports). Activation enthalpies for pyrolytic eliminations are around 40 kcal/mol and are unlikely to occur during extraction or GC analysis. PMID:20734926

    The results of the conversion of a VGO over six equilibrium commercial FCC catalysts with different formulations in a batch CREC Riser Simulator laboratory reactor at 500 and 550 C, catalyst to oil ratio 6.1 and reaction times from 3 to 30 s, were analyzed. It was possible to define the main catalyst characteristics in terms of various evaluation items, such as activity, gasoline yield and quality, LPG yield and coke yield, or the yields of particular compounds like, e.g., isobutane. Important differences in activity between catalysts were not observed, but catalyst properties reflected clearly as significant differences in gasoline, LPG or coke selectivities. Particularly, catalyst's hydrogen transfer properties impacted on gasoline composition and isobutane yield. The results showed that the CREC Riser Simulator reactor is an important tool for the evaluation of both commercial catalysts and feedstocks and process conditions. (author)

  16. The importance of water transit time and mineral dissolution kinetics for the flux of weathering products

    Science.gov (United States)

    Erlandsson, Martin; Bishop, Kevin; Köhler, Stephan; Amvrosiadi, Nino

    2016-04-01

    Soil mineral weathering is one of the major sources of base cations (BC), which play a dual role for a forest ecosystem; they function both as plant nutrients, and for buffering against acidification of catchment runoff. On a long-term basis, the soil weathering rates will determine the highest sustainable forest productivity without causing acidification. It is believed that the hydrologic residence time play a key role in determining weathering rates on a landscape scale. In this study, we investigate the significance of the water transit residence time (WTT) distribution for the transport of base cations to catchment runoff. By modelling hillslope flowpaths with different transit times, using the geochemical computing code PHREEQC, we demonstrate how in-stream dynamics as exemplified by elemental ratios can be explained by mineral dissolution kinetics and equilibria. Specifically, we hypothesize that equilibrium of plagioclase regulates the delivery of base cations and silica to catchment runoff. These patters can be seen in field data from 10 years of sampling from a nested-catchment, where the Na+/BC and the Si/BC-ratios vary systematically with WTT on both a temporal and a spatial scale. This behavior has implications for the total transport of products from mineral dissolution to catchment runoff. As the water entering the stream is a mixture of water with different transit times, the composition of stream water will not only be dependent on the average WTT, but also on the shape of the WTT distribution. For the base cations associated with minerals that becomes supersaturated or with precipitating secondary phases within the range of WTT, i.e. Na+ and K+, the tails of "old water" of the WRT-distribution will not contribute to any extra transport of these elements. Finally, we use the derived relationships to estimate the transport of weathering products from a forested hillslope, given the modelled WRT distribution.

  17. Evaluating the Potential Importance of Monoterpene Degradation for Global Acetone Production

    Science.gov (United States)

    Kelp, M. M.; Brewer, J.; Keller, C. A.; Fischer, E. V.

    2015-12-01

    Acetone is one of the most abundant volatile organic compounds (VOCs) in the atmosphere, but estimates of the global source of acetone vary widely. A better understanding of acetone sources is essential because acetone serves as a source of HOx in the upper troposphere and as a precursor to the NOx reservoir species peroxyacetyl nitrate (PAN). Although there are primary anthropogenic and pyrogenic sources of acetone, the dominant acetone sources are thought to be from direct biogenic emissions and photochemical production, particularly from the oxidation of iso-alkanes. Recent work suggests that the photochemical degradation of monoterpenes may also represent a significant contribution to global acetone production. We investigate that hypothesis using the GEOS-Chem chemical transport model. In this work, we calculate the emissions of eight terpene species (α-pinene, β-pinene, limonene, Δ3-carene, myrcene, sabinene, trans-β-ocimene, and an 'other monoterpenes' category which contains 34 other trace species) and couple these with upper and lower bound literature yields from species-specific chamber studies. We compare the simulated acetone distributions against in situ acetone measurements from a global suite of NASA aircraft campaigns. When simulating an upper bound on yields, the model-to-measurement comparison improves for North America at both the surface and in the upper troposphere. The inclusion of acetone production from monoterpene degradation also improves the ability of the model to reproduce observations of acetone in East Asian outflow. However, in general the addition of monoterpenes degrades the model comparison for the Southern Hemisphere.

    The opinions of seven respondent groups about the relative importance of different practices pertaining to the welfare of Australian beef cattle, sheep and goats were surveyed. Respondent groups comprised farmers, livestock transportation representatives, veterinarians, meat processors, animal welfare advocates, animal welfare scientists and government officers. The survey consisted of a web-based adaptive conjoint analysis questionnaire, which was administered to a sample population that was selected randomly for large respondent groups and comprehensively for small groups. The hierarchy of opinion concerning the importance of the different beef cattle practices was: stockmanship > ground (road and rail) transport > spaying > food supply > dehorning > stunning > shelter > identification > pretransport food and water deprivation > castration > sea transport > mustering > confinement. For sheep/goat practices the hierarchy was: parasite control > mulesing > shelter > stockmanship > tail docking > ground transport > feeding > predation > stunning > castration > pretransport food and water deprivation > sea transport > mustering. The method of performing invasive procedures was perceived as less important than the provision of pain relief. Differences in opinion were evident between respondent groups, with animal welfare advocates tending to focus on painful procedures more than those with direct involvement in the industry.

    2010-06-01

    Full Text Available Livestock systems in Colombia have been developed taking concepts and technologies from the green revolution, where gramineous monocrop is privileged over arboreal cover in grazing lands. This model has not taken into account the climatic conditions of the different tropical ecosystems, in which variables as temperature, relative humidity and evaporation can limit the animal´s productive and reproductive efficiency, besides being a risk factor for illness occurrence in the herd. Bos Taurus and Bos Indicus breeds show termoneutral ranges where its genetic potential can be express. However, out of this comfort area animals can enter in caloric stress which in consequence reduces its performance and sometimes can end up causing death. Silvopastoral systems comprise several functions; it contributes to lessen caloric stress since temperature under the tree canopy can reach between 2 and 9°C lower in comparison to open pastures. Differences in temperature reduction have been found among silvopastoral systems and species, being the tree group arrangements and the species with high density canopy, those with superior effect. Interactions among components should be analyzed in order to design systems that incorporate enough arboreal cover to achieve caloric stress reductions, but without affecting forage production in pastures. Silvopastoral systems contribute to improve animal welfare.

  1. The importance of phytoplankton production for carbon budgets in a semiarid floodplain wetland

    Directory of Open Access Journals (Sweden)

    Álvarez-Cobelas, Miguel

    2011-12-01

    Full Text Available Phytoplankton production (PP in wetlands is not measured as often as that of macrophytes. A three year-study during a period of sustained high flooding was undertaken in a central Spanish floodplain wetland (Las Tablas de Daimiel National Park to determine net PP, its spatial heterogeneity and controlling factors, and compare it with primary production in macrophyte communities. This enabled us to estimate carbon budgets for each community. All PP variables showed high spatial and temporal variability among sites, resulting in low coherence even when flooding connected all sites. Net PP corresponded to 25- 36% of submerged plant production and 3-10% of helophyte production. Net PP was controlled by different size fractions of phytoplankton biomass at different wetland sites. Neither nutrients nor zooplankton affected net PP or productivity. A high spatiotemporal variability of PP in wetlands occurs arising from complex processes that affect the underwater light field. Carbon budgets of phytoplankton often exceeded those of submerged macrophytes and attained between 4 and 37% of helophyte budgets. Although usually considered to be marginal, our study shows that PP in the open water of wetlands should be taken into account for determining accurate wetland carbon budgets, mostly in periods of high flooding, which often result in changing the carbon budget of primary producers.

    In this paper the construction, technological parameters and operation of Gabcikovo (primary hydro energy power) and Cierny Vah (secondary hydro energy power) are described. Construction of the hydroelectric power plant (HPP) Gabcikovo started in 1978 as a part of a system of hydro power projects Gabcikovo-Nagymaros. Basic technical data are: installed capacity 8 x 90 MW, production in an average aqueous year 2.650 GWh, number of hydroelectric generating sets (HGS) 8, turbine flow 8 x 413-636 m3/s, head 12.9-24 m.The Gabcikovo plant produced 9.163 GWh of electricity from the beginning of its operation till the end of 1966. The construction of the pumped storage plant (PSP) Cierny Vah started in 1976 and it was put into operation at the end of 1980. The main goal of the PSP Cierny Vah is to meet the control functions of an electrification system of the Slovak Republic, a substitute function in the cases of unexpected power outages and a planned electricity production from re-pumping. Technological parts are: six re-pumping vertical HGS in a three machine arrangement - a motor-generator, a turbine, a pump - are located in three double-blocks. Basic technical data: installed capacity 6 x 122.4 MW + 0.768 MW, yearly production 1,281 GWh, number of HGS 6, number of domestic hydroelectric generating sets 1, turbine flow 3 x 30 m/s, pump flow 6 x 22 m3/s, upper reservoir volume 3.7 mil. m3, max. head 434 m, peak time 5.71 hour, pumping time 7.78 hour, re-pumping cycle efficiency 74.36%. From putting the PSP into operation till the end of 1996, the HGS in operation 145,269 hours in total, including 53,332 hours in a turbine mode of operation, 70,293 hours in a pumping mode operation and 21,644 hours in a compensation mode operation.

  5. The importance of Soret transport in the production of high purity silicon for solar cells

    Science.gov (United States)

    Srivastava, R.

    1985-01-01

    Temperature-gradient-driven diffusion, or Soret transport, of silicon vapor and liquid droplets is analyzed under conditions typical of current production reactors for obtaining high purity silicon for solar cells. Contrary to the common belief that Soret transport is negligible, it is concluded that some 15-20 percent of the silicon vapor mass flux to the reactor walls is caused by the high temperature gradients that prevail inside such reactors. Moreover, since collection of silicon is also achieved via deposition of silicon droplets onto the walls, the Soret transport mechanism becomes even more crucial due to size differences between diffusing species. It is shown that for droplets in the 0.01 to 1 micron diameter range, collection by Soret transport dominates both Brownian and turbulent mechanisms.

This article presents the model of a lean startup, which can be applied to an organization regardless of its size or environment. It also emphasizes the conditions of extreme uncertainty under which the commercialization of new technology is carried out. The lean startup philosophy advocates efficient use of resources by introducing a minimum viable product to the market as soon as possible in order to test its value and the entrepreneur’s growth projections. This testing is done by running experiments that examine the metrics relevant to three distinct types of the growth. These experiments bring about accelerated learning to help reduce the uncertainty that accompanies commercialization projects, thereby bringing the resulting new technology to market faster.

The conclusion of this research is that the highest dry matter yield (4.33 t ha-1 and crude protein yield was obtained with the inoculation of new genotype winter pea G3.

  8. The importance of nuclear energy in stabilizing or reducing electricity production costs

    International Nuclear Information System (INIS)

    Nuclear power plants are characterized by their high investment cost per installed kilowatt and the financial charges associated with that investment generally represent two thirds of the cost of producing a kilowatt-hour of nuclear origin. The cost of the fuel cycle is approximately one-fourth of this cost, the balance consisting of expenditure on personnel. Although natural uranium is the raw material of this cycle, it represents only a fraction of the cost of the cycle, the bulk of which arises out of expenditures associated with a whole range of operations - enrichment, fabrication, fuel reprocessing as well as treatment and storage of waste. This high value of the ratio of investment cost to natural uranium cost is a determining factor in the stabilization of the cost of electricity generation, inasmuch as this situation actually shelters the nuclear kilowatt-hour from price fluctuations as sudden and serious as those affecting fossil fuels. Furthermore, the easy and relatively inexpensive storage of uranium provides power generation of nuclear origin with energy reserves which protect it against unforeseen supply complications due to crises and conflicts of all kinds. Of course, the kilowatt-hour production cost of a nuclear unit depends on a number of parameters whose influence has to be evaluated - in particular, the availability of the facility, itself a function of the quality of its design, construction and operation. In all countries having the technical know-how to ensure this availability, long experience has shown the definite economic advantage of the nuclear kilowatt-hour over the traditional kilowatt-hour. Countries which have staked heavily on nuclear energy have seen that this advantage has very favourable repercussions on the production cost of electric energy. (author). 6 figs, 3 tabs

    The YjgF/YER057c/UK114 family proteins are highly conserved across all three domains of life, and most of them currently have no clearly defined biological roles. In vitro, these proteins were found to hydrolyze the enamine/imine intermediates generated from serine or threonine, and were renamed Reactive Intermediate Deaminase A (RidA). RidA was recently discovered in Arabidopsis thaliana, and by deaminating the toxic enamine/imine intermediates, it prevents the inactivation of many functionally important pyridoxal 5′-phosphate (PLP)-containing enzymes in plants such as branched-chain aminotransferase BCAT (IlvE). In this study, we determined the crystal structure of Arabidopsis thaliana RidA in the apo form, as well as RidA complexed with the ligand pyruvate. RidA forms the trimeric, barrel-like quaternary structure and inter-subunit cavities, and resembles most RidA family members. Each pyruvate molecule binds to the interface between two subunits, and the recognition of pyruvate is achieved by the interactions with R165 and T167. From sequence alignment and structural superposition, we identified a series of key residues responsible for the trimer assembly, whose importance was confirmed by enzymatic assays. This study provides structural insight into RidA functions in plants. PMID:27458092

  10. The importance of grasslands for animal production and other functions: a review on management and methodological progress in the tropics.

    Boval, M; Dixon, R M

    2012-05-01

    The global importance of grasslands is indicated by their extent; they comprise some 26% of total land area and 80% of agriculturally productive land. The majority of grasslands are located in tropical developing countries where they are particularly important to the livelihoods of some one billion poor peoples. Grasslands clearly provide the feed base for grazing livestock and thus numerous high-quality foods, but such livestock also provide products such as fertilizer, transport, traction, fibre and leather. In addition, grasslands provide important services and roles including as water catchments, biodiversity reserves, for cultural and recreational needs, and potentially a carbon sink to alleviate greenhouse gas emissions. Inevitably, such functions may conflict with management for production of livestock products. Much of the increasing global demand for meat and milk, particularly from developing countries, will have to be supplied from grassland ecosystems, and this will provide difficult challenges. Increased production of meat and milk generally requires increased intake of metabolizable energy, and thus increased voluntary intake and/or digestibility of diets selected by grazing animals. These will require more widespread and effective application of improved management. Strategies to improve productivity include fertilizer application, grazing management, greater use of crop by-products, legumes and supplements and manipulation of stocking rate and herbage allowance. However, it is often difficult to predict the efficiency and cost-effectiveness of such strategies, particularly in tropical developing country production systems. Evaluation and on-going adjustment of grazing systems require appropriate and reliable assessment criteria, but these are often lacking. A number of emerging technologies may contribute to timely low-cost acquisition of quantitative information to better understand the soil-pasture-animal interactions and animal management in

    2008-07-01

    Despite much progress in characterizing asphaltenes, little is known about the relation between the size and shape of asphaltenes and their impact on flow assurance. This lack of understanding is related primarily to the fact that the asphaltenes structure found in crudes depends on many geochemical processes that are generally not included as input for flow assurance studies. The geochemical processes that are important to asphaltenes are type of source rock and deposited organic matter, maturity, migration history, and processes in the reservoir as hybridization and biodegradation. A careful examination of geochemical processes can reveal the relationship between asphaltene behaviour in fields that are seemingly very different or distant. This paper provided some examples of these relationships. Understanding the structure of asphaltenes is critical and warrants the further development of methods for more accurate characterization.

    Full Text Available Home appliances are among basic requirements of anyone in the world and it is always important to find out about factors influencing this industry. Therefore, the purpose of this study is to provide a comprehensive model to detect major factors influencing on consumer purchasing intention. For this purpose, the proposed study designs a questionnaire and distributes it among 400 customers who have some experiences on purchasing home appliances in city of Tehran, Iran, recently. Cronbach alpha was calculated for all components of the survey and they were all well above the minimum acceptable level. We analyzed the data using structural equation modeling via LISREL and the results of this survey show that brand familiarity, brand trust, and perceived value have significant positive effects on consumers purchase intention.

    Full Text Available Yield capacity, quality of grapes and resistance to downy mildew attack remain the important breeding objectives for grape. For these traits were analyzed more than 2200 F1 hybrids, belonging to eight combinations of wine grape. In each combination cv. Gewurztraminer was used, both as maternal and as paternal genitor, the other genitor being represented by an interspecific selection, rated as highly resistant to diseases (derived from Saint Emilion x Rayon d'or and Seyve-Villard 12-375 x Queen of Vine combinations. The rating of susceptibility to downy mildew in the tested hybrid individuals was performed in natural conditions of infection by visual observation and scored from "0"(no infection on leaves to "5" (very severe infection, and the scale 1-5 was used for bunch number per hybrid and sugar content in grape must. Obvious differences for analysed traits were noted both among the studied combinations and within the same combination, depending on whether 'Gewurztraminer' has been used as maternal or as paternal genitor. These results suggest possible maternal effects on the phenotypic expression of these traits in grape vine. Variability indices (s% were high and very high in all combinations (22.1-39.4% for response to Plasmopara viticola attack; 24.7-29.7% for bunch number per vine; 32.4-44.0% for sugar content in must, offering a good background for an efficient selection. The characters seem to be polygenically inherited, with high and very high heritability indices in the broad sense. The low values computed for heritability in the narrow sense suggest that except additive effects, epistasis and dominance effects have an important role in the phenotypic expression of vine yield capacity, sugar content of the must and resistance to downy mildew attack.

  15. Study on the potential imports by member states of agricultural products containing radiocesium concentrations in excess of EC limits

    International Nuclear Information System (INIS)

    As a consequence of the Chernobyl accident, the European Commission maintains Council Regulation (EEC) number 737/90 which sets out the conditions governing the import of agricultural products originating in third countries and includes maximum permitted level (MPL) that shall be applied in respect of contamination with radiocesium. The main objective of the study was to identify agricultural products which might exceed the MPL of radiocesium. The results show that mushroom and berries from Norway or Russia or Belarus or Ukraine may exceed the MPL. Reindeer meat from Norway will stay suspicious for at least 30 years as well as meat from wild animals originating from Russia, Belarus and Ukraine and some other countries. Some agricultural products like living cows or horses, poultry,... can be excluded from the list except for products issued from areas with strong contamination

    2005-12-01

    To help manage red imported fire ant, Solenopsis invicta Buren, invasion, several types of pest management systems have been developed, including baits. To accurately test liquid bait effectiveness in the laboratory, we determined that starvation time of 96 h is required for laboratory fire ants to simulate foraging ants in the field. We measured density and viscosity of two commercial baits and 20% sugar water at 25 degrees C and then compared amount of material consumed per ant at these physical properties. Mean densities of 20% sugar water, Dr. Moss, and Terro were 1.051, 1.287, and 1.354 g/ml, respectively, and viscosity of each bait treatment varied in the same order but more drastically (1.7, 32, and 400 centipoises, respectively). Field and laboratory studies demonstrated that bait acceptability may be affected by toxicant and physical properties. Baits that are more dense have more mass per volume and may cause the ant to cease feeding with a lower crop load than when they feed on sugar water. Ants that feed on formulated baits exhibit feeding behaviors different from those that occur when feeding on sugar water. At first glance, one might conclude that the difference is because of the toxicant, but our findings suggest that physical properties of baits may be a factor in this change in feeding behavior.

  17. Importance of polarization transfer in reaction products for interpreting and analyzing CIDNP at low magnetic fields

    The magnetic field dependence of Chemically Induced Dynamic Nuclear Polarization (CIDNP) was studied for the amino acids N-acetyl histidine, N-acetyl tryptophan and N-acetyl tyrosine. It is demonstrated that at low field CIDNP is strongly affected by polarization redistribution in the diamagnetic molecules. Such a polarization transfer is of coherent nature and is due to spin coherences formed together with non-equilibrium population of the spin states. These coherences clearly manifest themselves in an oscillatory time dependence of polarization. Polarization transfer effects are most pronounced at nuclear spin Level Anti-Crossings (LACs), which also result in sharp features in the CIDNP field dependence. Thus, polarization transfer is an important factor, which has to be taken into account in order to interpret low-field CIDNP data on both qualitative and quantitative level. Possible applications of polarization transfer phenomena are also discussed in the paper. In particular, the role of LACs in spin order transfer is highlighted: LACs provide a new tool for precise manipulation of spin hyperpolarization and NMR enhancement of selected target spins.

    1977-01-01

    The burrowing nematode, Radopholus similis, attacks agronomic and horticultural crops and many weeds, and is reported to reproduce on more than 250 plant species. Two races of R. similis are recognized. Although one race attacks citrus and the other race does not, they are morphologically similar. At present, the citrus race is found attacking citrus only in Florida, U.S.A., but it is known to infect more than 250 species and varieties of noncitrus plants. Although it has many hosts, R. similis is probably most widely distributed on banana and is found worldwide. Although best known as a pest of Piper nigrum, Musa spp., and Citrus spp., it also attacks many crops that are important in world commerce and in subsistence-type agriculture, a factor which makes it a significant agricultural pest. Worldwide dissemination occurs primarily when parasitized plants are moved into areas where the pest could adapt. Yield losses of 12.5 tons/ha in bananas have been reported from R. similis infection. Infections suppress orange and grapefruit yields as much as 70-80%. Because of the severity of R. similis damage (particularly to banana and citrus), extensive control programs have been developed. Prevention, cultural practices, resistant varieties, and chemical pesticides interact to reduce losses. PMID:19305565

  19. The Relationship between Major Oil Products Consumption and Efficiency of Industry Sector in Selected Oil Exporting and Importing Countries

    2013-11-01

    Full Text Available The aim of this study is to investigate the realization of the law of diminishing returns in usage of major oil products in the industry sector of some oil exporting and importing countries during 2002- 2008. To achieve this aim, in a first stage the efficiency of industry sector of countries has been calculated using DEA window analysis and then in the second stag the existence of an inverted U' shape relationship between major oil product consumption and efficiency has been tested in the context of dynamic panel data (GMM approach. The results confirm this relationship in each group of countries except that the turning point in the case of oil importing countries is much higher than oil exporting countries. This firstly suggests that oil dependence in oil importing countries is more than oil exporting countries and secondly indicates that the industry sector of oil importing countries have advanced technology and high scale and capacity so that they can take benefits of oil products consumption without decrease in efficiency.

  20. Host cell-induced signaling causes Clostridium perfringens to upregulate production of toxins important for intestinal infections.

    2014-01-01

    Clostridium perfringens causes enteritis and enterotoxemia in humans and livestock due to prolific toxin production. In broth culture, C. perfringens uses the Agr-like quorum sensing (QS) system to regulate production of toxins important for enteritis/enterotoxemia, including beta toxin (CPB), enterotoxin, and epsilon toxin (ETX). The VirS/VirR two-component regulatory system (TCRS) also controls CPB production in broth cultures. Both the Agr-like QS and VirS/VirR systems are important when C. perfringens senses enterocyte-like Caco-2 cells and responds by upregulating CPB production; however, only the Agr-like QS system is needed for host cell-induced ETX production. These in vitro observations have pathophysiologic relevance since both the VirS/VirR and Agr-like QS signaling systems are required for C. perfringens strain CN3685 to produce CPB in vivo and to cause enteritis or enterotoxemia. Thus, apparently upon sensing its presence in the intestines, C. perfringens utilizes QS and TCRS signaling to produce toxins necessary for intestinal virulence. PMID:24061146

  1. Is importing second-hand products a good thing? The cases of computers and tires in Cambodia

    International Nuclear Information System (INIS)

    Is importing second-hand products (SHPs) good for Cambodia? To answer this question, one must seriously consider environmental and social effects. The main objective of this study is to identify and assess the economic, social, and environmental impacts of imported SHPs to determine whether or not Cambodia benefits. Imported second-hand computers (SHPCs) and second-hand tires (SHTs) were selected as cases for the study. The study used a scaling checklist to identify significant impacts of these two imported items. Significant impacts were ranked and rated into a single value (score) for integration. Integrated impact assessment showed that imported SHPCs create a very small positive impact (+ 0.1 of + 5) and imported SHTs generate a large negative impact (- 2.83 of - 5). These scores are mainly the result of environmental impact, predominantly waste issues. Thus, current imports of SHPCs and SHTs do not really benefit Cambodia, but instead cause serious environmental problems from their waste issues. The import serves as a channel to transfer waste into developing countries.

    This paper examines how international production/distribution networks provide individual firms with exporting/importing responsiveness to exchange rate movements. With the micro-data of Japanese manufacturing firms from 1994 to 2004, we find that firms' exports tend to respond to exchange rate movements, in particular (1) when firms are large in size, (2) when majority-owned affiliates are dominant among their foreign affiliates, and (3) when their intra-firm trade ratio is moderately high. ...

  3. Characterization of extended-spectrum β-lactamase (ESBL) producing non-typhoidal Salmonella (NTS) from imported food products.

    Food contaminated with extended-spectrum β-lactamase (ESBL)-producing Salmonella enterica has emerged as an important global issue due to the international food-product trade. Therefore, the purpose of this study was to investigate whether imported food products can serve as a reservoir for non-typhoidal Salmonella (NTS) that can transmit β-lactam-resistance to humans through ingestion of the contaminated food. NTS isolates (n=110) were collected from various imported food products (n=3480) from 2011 to 2013. The NTS isolates were analyzed by serotyping, antimicrobial susceptibility tests, and plasmid profiling. Salmonella ser. Weltevreden, Salmonella ser. Newport, Salmonella ser. Senftenberg, Salmonella ser. Virchow, Salmonella ser. Enteritidis, Salmonella ser. Typhimurium, and Salmonella ser. Bareilly were the most prevalent serovars. Nine NTS strains were resistant to ampicillin and/or one or more cephalosporins (MIC>32 μg/mL). Polymerase chain reaction (PCR) detection revealed that all nine isolates carried the bla(TEM-1) β-lactamase gene, with or without the bla(CTX-M-9) or bla(OXA-1) genes. Two isolates, PSS_913 and PSS_988, exhibited decreased susceptibility to extended-spectrum cephalosporins and ampicillin. Plasmids ranging in size from less than 8 to over 165 kbp, from all of the 9 resistant isolates, belonged to the IncHI1, IncI1, IncN, or IncX groups. Conjugation experiments and Southern hybridization, using bla(TEM-1), confirmed the plasmid-mediated transfer of ESBL genes, which resulted in increased MICs of β-lactams for Escherichia coli transconjugants. The contamination of imported food products by NTS with conjugative plasmid-borne ESBL genes may contribute to the spread of ESBL-producing NTS and compromise the therapeutic activity of extended-spectrum β-lactam antibiotics.

    2016-04-01

    Certain groups of soil invertebrates, namely scarab beetles and millipedes, are capable of emitting considerable amounts of methane due to methanogens inhabiting their gut system. It was already pointed out in the early 1990's, that these groups of invertebrates may represent a globally important source of methane. However, apart from termites, the importance of invertebrates for the soil methane budget is still unknown. Here, we present preliminary results of a laboratory soil incubation experiment elucidating the influence of forest cockchafer larvae (Melolontha hippocastani FABRICIUS) on soil methane cycling. In January/February 2016, two soils from two different management systems - one from a pine forest (extensive use) and one from a vegetable field (intensive use) - were incubated for 56 days either with or without beetle larvae. Net soil methane fluxes and larvae methane emissions together with their stable carbon isotope signatures were quantified at regular intervals to estimate gross methane production and gross methane oxidation in the soils. The results of this experiment will contribute to testing the hypothesis of whether methane production hotspots can significantly enhance the methane oxidation capacity of soils. Forest cockchafer larvae are only found in well-aerated sandy soils where one would usually not suspect relevant gross methane production. Thus, besides quantifying their contribution to net soil methane fluxes, they are also ideal organisms to study the effect of methane production hotspots on overall soil methane cycling.

  5. Availability of biomass for energy production. GRAIN: Global Restrictions on biomass Availability for Import to the Netherlands

    International Nuclear Information System (INIS)

    great opportunities for a sustainable supply of energy and materials, but on the other hand it bears large ecological and economical risks, such as deforestation and competition with food production. It is therefore of the utmost importance to formulate minimum requirements for large-scale bio-energy projects and international trade in biomass energy. For international trade in biomass energy it is important to identify regions with a future biomass energy surplus, related to their own energy consumption. Exporting this surplus would have to be done as efficiently as possible, with regard to CO2 emission reduction. Transatlantic shipments of wood have to be balanced against local conversion and shipping the fuel. An important recommendation to the Netherlands government about the possible future import of biomass is therefore: increase the knowledge and insights in the possible consequences of large scale import of biomass energy. This can be done by setting up a limited number of pilot projects for the trade in bio-energy, and by monitoring these projects very carefully, supported by research activities. Such pilot projects can also provide a better understanding in how broad the support for these activities is, both in the Netherlands as well in exporting countries. In the long run much more knowledge and information is required about which regions would be most suited for a sustainable production and trade in biomass energy. It will be necessary to develop and introduce a 'FSC' type mark for biomass-based energy carriers. There are still a number of crucial research questions in areas such as: economic drivers of land use, competition of biomass with other land uses, and competition with other sources of energy and materials. These interactions need to be studied at local/regional level, taking into account the effect of technological and economical changes in time. In addition there are complex questions in the field of optimising the allocation of biomass resources

    Propionibacteria are actinobacteria consisting of two principal groups: cutaneous and dairy. Cutaneous propionibacteria are considered primary pathogens to humans, whereas dairy propionibacteria are widely used in the food and pharmaceutical industries. Increasing attention has been focused on improving the performance of dairy propionibacteria for the production of industrially important chemicals, and significant advances have been made through strain engineering and process optimization in the production of flavor compounds, nutraceuticals, and antimicrobial compounds. In addition, genome sequencing of several propionibacteria species has been completed, deepening understanding of the metabolic and physiological features of these organisms. However, the metabolic engineering of propionibacteria still faces several challenges owing to the lack of efficient genome manipulation tools and the existence of various types of strong restriction-modification systems. The emergence of systems and synthetic biology provides new opportunities to overcome these bottlenecks. In this review, we first introduce the major species of propionibacteria and their properties and provide an overview of their functions and applications. We then discuss advances in the genome sequencing and metabolic engineering of these bacteria. Finally, we discuss systems and synthetic biology approaches for engineering propionibacteria as efficient and robust cell factories for the production of industrially important chemicals.

    Full Text Available Hydrogen is one of the most promising energy sources of the future enabling direct production of power and heat in fuel cells, hydrogen engines or furnaces with hydrogen burners. One of the last remainder problems in hydrogen technology is how to produce a sufficient amount of cheap hydrogen. One of the best options is large scale thermochemical production of hydrogen in combination with nuclear power plant. copper-chlorine (CuCl cycle is the most promissible thermochemical cycle to produce cheap hydrogen.This paper focuses on a CuCl cycle, and the describes the models how to calculate thermodynamic properties. Unfortunately, for many components in CuCl cycle the thermochemical functions of state have never been measured. This is the reason that we have tried to calculate some very important thermophysical properties. This paper discusses the mathematical model for computing the thermodynamic properties for pure substances and their mixtures such as CuCl, HCl, Cu2OCl2 important in CuCl hydrogen production in their fluid and solid phase with an aid of statistical thermodynamics. For the solid phase, we have developed the mathematical model for the calculation of thermodynamic properties for polyatomic crystals. In this way, we have used Debye functions and Einstein function for acoustical modes and optical modes of vibrations to take into account vibration of atoms. The influence of intermolecular energy we have solved on the basis of Murnaghan equation of state and statistical thermodynamics.

    1999-01-01

    The recent decade has seen a concentration in the food retail sector in Europe (Eurostat, 1997), and this has increased the importance of understanding value creation in the retail industry, as retailers are becoming the gatekeepers to the consumer mar-ket (Skytte & Blunch 1998; Sternquist 1994......). The creation of value in a product or service is also widely recognised as the pri-mary source of competitive advantage (Woodruff & Gardial, 1996). However, so far, consequences and values have not been analysed in relation to retail buyer behaviour, as previous research has focused on specific buyer...... attributes (Dzever 1993; Johnston 1996; Möller 1985; Skytte 1998;Woodruff 1997).

    predictions, we know relatively little about the plot and landscape-level controls on tundra biogeochemical cycling in wintertime as compared to summertime. We investigated the relative influence of vegetation type and climate on CO2 production rates and total wintertime CO2 release in the Scandinavian...... northern Sweden. Both climate and vegetation type were strong interactive controls on ecosystem CO2 production rates during winter. Of all variables tested, soil temperature explained by far the largest amount of variation in respiration rates (41-75%). Our results indicate that vegetation type only...... respiration, suggesting that spatial variations in maximum snowdepth may be a primary determinant of regional patterns of wintertime CO2 release. Together, our results have important implications for predictions of how the distribution of tundra vegetation types and the carbon balances of arctic ecosystems...

A simple production index was constructed with data collected from the Washington State Department of Agriculture (WSDA), the United States Bureau of the Census, and the United States Department of Agriculture (USDA). Hanford Environmental Dose Reconstruction (HEDR) Project staff from Battelle, Pacific Northwest Laboratories, in cooperation with members of the Technical Steering Panel (TSP), selected lettuce and spinach as the produce pathways most likely to impact dose. County agricultural reports published in 1956 provided historical descriptions of the predominant distribution patterns of fresh lettuce and spinach from production regions to local population centers. Pathway rankings and screening dose estimates were calculated for specific populations living in selected locations within the HEDR study area.

    Full Text Available Mycological analysis of local meat products (luncheon and minced meat and livers of poultry and imported bulls resulted in isolation of 29 fungal species related to 10 genera. The average total counts of fungi per gram fresh weight ranged from 2680 in luncheon to 7460 in livers of poultry. Aspergillus was the most prevalent genus followed by Penicillium where they were isolated from all the examined substrates. Many of the isolated fungi might have mycotoxin-producing potential. Results of mycotoxins analysis revealed that, 45% of the examined samples were positive. Aflatoxins (B1, B2, G1 and G2, ochratoxin A, citrinin and sterigmatocystin were detected. Samples of livers from imported bulls contained the highest levels of aflatoxins and ochratoxin A (54 and 145 μg/kg, respectively. The majority of the remaining mycotoxin contaminated samples contained a high level which was far above the acceptable ones. The hazardous effects of these natural pollutants were discussed.

    Full Text Available Decisions are a result of choices made between several alternatives and will affect all participants in the decision-making process. In this paper we analyze the Monte Carlo simulation as an important management tool in evaluating decisions under risk. The method is particularly useful in simulating decision problems. For example, the profit that could be achieved if a company launches a new product may depend on a number of factors (market share, advertising, production costs, launch costs, the lifetime of the product, etc. The company manager should identify all factors that could affect profit and then to consider the large number of ways in which these factors may interrelate. In such situations it is recommended company manager to divide the problem into smaller parts, asking him to estimate the probability distribution for market share, for advertising, for the cost of launch. Once they were obtained it can be determined their combined effect in order to obtain the probability distribution of profit. Through computer can generate a large number of possible combinations of situations where you choose a particular course of action. Upon completion of the simulation possible combination will be generated mostly while the least possible combination will be generated less frequently. For exemplification we selected a company producing shoes in Cluj market who wants to launch a new model for autumn-winter 2013-2014. In the current period the company has limited production capacity, has a number of additional contracts honored and general economic crisis situation makes money availability to be extremely limited. Accordingly, the company will have to choose a single product to be launched next season. The company will have to decide which of the two new products to be launched on the market: a model of boots for men in business class or a new model of women\\'s boots of the same class business. The company is not sure either production costs or

  13. Improving the productivity of imported dairy cattle on small-holder farms in Morocco through supplementation with fish silage blocks

    International Nuclear Information System (INIS)

    The present study was designed to identify problems that lower the productivity of imported dairy cattle in Morocco. For this purpose, a comprehensive survey was carried out on 8 small-holder farms over a period of two years. Analysis of the data collected indicated that in most of the herds reproductive performance was adequate (calving intervals ranging from 338 ± 11 to 420 ± 31 and services to conception ranging from 1.14 ± 0.13 to 1.91 ± 0.3), but the animals had difficulty in meeting the nutrient requirements for milk production. Although some farmers provided supplements to their animals they were either expensive or not available at the required time. One possible way of alleviating the problem was the introduction of a fish by-product into the dairy cattle ration. Two experiments were conducted, one at the Institute experimental farm and the other at a private farm selected for the survey. In both experiments, fish silage blocks were incorporated into the ration of dairy cattle in replacement of an equal amount of the most commonly used supplements. The introduction of fish silage blocks in the ration did not affect their intake or body condition. In addition, the yield and quality of the milk were maintained. This substitution allowed the farmer to utilize by-products from the fish industry which are readily available and less costly than most conventional supplementary feeds. It is concluded, that the proposed utilization of fish silage blocks will reduce the production costs and improve the economic efficiency of the small-holder farms. (author)

  14. The Importance of the Ionic Product for Water to Understand the Physiology of the Acid-Base Balance in Humans

    Directory of Open Access Journals (Sweden)

    María M. Adeva-Andany

    2014-01-01

    Full Text Available Human plasma is an aqueous solution that has to abide by chemical rules such as the principle of electrical neutrality and the constancy of the ionic product for water. These rules define the acid-base balance in the human body. According to the electroneutrality principle, plasma has to be electrically neutral and the sum of its cations equals the sum of its anions. In addition, the ionic product for water has to be constant. Therefore, the plasma concentration of hydrogen ions depends on the plasma ionic composition. Variations in the concentration of plasma ions that alter the relative proportion of anions and cations predictably lead to a change in the plasma concentration of hydrogen ions by driving adaptive adjustments in water ionization that allow plasma electroneutrality while maintaining constant the ionic product for water. The accumulation of plasma anions out of proportion of cations induces an electrical imbalance compensated by a fall of hydroxide ions that brings about a rise in hydrogen ions (acidosis. By contrast, the deficiency of chloride relative to sodium generates plasma alkalosis by increasing hydroxide ions. The adjustment of plasma bicarbonate concentration to these changes is an important compensatory mechanism that protects plasma pH from severe deviations.

    In the developing heart, the epicardium is a major source of progenitor cells that contribute to the formation of the coronary vessel system. These epicardial progenitors give rise to the different cellular components of the coronary vasculature by undergoing a number of morphological and physiological changes collectively known as epithelial to mesenchymal transformation (EMT). However, the specific signaling mechanisms that regulate epicardial EMT are yet to be delineated. In this study we investigated the role of TGF{beta}2 and hyaluronan (HA) during epicardial EMT and how signals from these two molecules are integrated during this important process. Here we show that TGF{beta}2 induces MEKK3 activation, which in turn promotes ERK1/2 and ERK5 phosphorylation. TGF{beta}2 also increases Has2 expression and subsequent HA production. Nevertheless, inhibition of MEKK3 kinase activity, silencing of ERK5 or pharmacological disruption of ERK1/2 activation significantly abrogates this response. Thus, TGF{beta}2 promotes Has2 expression and HA production through a MEKK3/ERK1/2/5-dependent cascade. Furthermore, TGF{beta}2 is able to induce epicardial cell invasion and differentiation but not proliferation. However, inhibition of MEKK3-dependent pathways, degradation of HA by hyaluronidases or blockade of CD44, significantly impairs the biological response to TGF{beta}2. Taken together, these findings demonstrate that TGF{beta}2 activation of MEKK3/ERK1/2/5 signaling modulates Has2 expression and HA production leading to the induction of EMT events. This is an important and novel mechanism showing how TGF{beta}2 and HA signals are integrated to regulate changes in epicardial cell behavior.

  16. The Importance of Considering Product Loss Rates in Life Cycle Assessment: The Example of Closure Systems for Bottled Wine

    Directory of Open Access Journals (Sweden)

    Olivier Jolliet

    2012-10-01

    Full Text Available Purpose: The objective of this study is to discuss the implications of product loss rates in terms of the environmental performance of bottled wine. Wine loss refers to loss occurring when the consumer does not consume the wine contained in the bottle and disposes of it because of taste alteration, which is caused by inadequate product protection rendering the wine unpalatable to a knowledgeable consumer. The decision of whether or not to drink the wine in such cases is guided by subjective consumer taste perception and wine quality expectation (drinking the bottle or disposing of the wine down the drain and replacing it with a new bottle. This study aims to illustrate the importance of accurately defining system boundaries related to wine packaging systems. Methods: The environmental impacts resulting from wine loss rates as related to two types of wine bottle closures—natural cork stoppers and screw caps—have been estimated based on literature review data and compared to the impact of the respective closure system. The system studied relates to the functional unit “a 750 mL bottle of drinkable wine” and includes bottled wine, bottle and closure production, wine production, wine loss and wine poured down the drain. Results: The range of wine alteration rates due to corked wine is estimated to be 2–5% based on interviews with wine experts. Consumer behavior was assessed through a sensitivity study on replacement rates. When the increase in loss rate with the cork stopper is higher than 1.2% (corresponding to 3.5% corked wine multiplied by a consumer replacement rate of 35%, the influence of losses on the impact results is higher than that of the closure material itself. The different closures and associated wine losses represent less than 5% of the total life cycle impact of bottled wine.

    2013-06-01

    Full Text Available The problem of personal debt is becoming more present in people's lives. What was once considered a personal problem only became a problem in part of the organizations, as when the employee is indebted, he ends up bringing their problems into the company. With that financial education has become increasingly important for companies. Today, 5% of large companies in Brazil have already inserted financial education for their employees. This research shows that recurring problems with debts lead employees to lose focus in their activities, to commit more errors in the process, missing more work and, in extreme cases, to resign in order to receive the guarantee fund for the working time. With financial education, employees learn to manage their finances, repay their debts and not acquiring debts that can not repay. Employees with no financial problems, increase productivity and quality of the process also. The advantage is for the company and the employee.

  20. Controls on the production, incorporation and decomposition of glomalin - a novel fungal soil protein important to soil carbon

    2003-11-20

    OAK B263 Glomalin is an operationally defined soil protein, produced by arbuscular mycorrhizal fungi (AMF), with importance in soil carbon sequestration through its relationship with soil aggregation. The goal of the project was to further explore the natural history of glomalin and to address several questions regarding basic behavior of this compound in soil (production, incorporation, decomposition). We have obtained a significant amount of novel information on the arbuscular mycorrhizal fungal soil protein, concerning factors controlling its production to mechanisms of incorporation and decomposition. These findings have resulted in 10 publications in peer-reviewed journals, with several more submitted or in preparation, and 16 contributed presentations at meetings. I have sought collaborative opportunities whenever they fit within the research proposed to enhance our productivity. Additionally, although not part of the original proposed work, we have made a significant effort to elucidate the molecular biology of glomalin (in response to Program Officer suggestions). In addition to peer-reviewed publications there have also been a number of invited presentations, including a keynote address delivered by the PI at the International Conference on Mycorrhizae (ICOM4) in Montreal, summer 2003. Two Master's students have been trained (and graduated), and a postdoctoral associate has been mentored, as well as numerous undergraduate researchers at UM. In this report I summarize the major findings of the project in the areas of glomalin production control (host factors, elevated CO2), incorporation, and decomposition. Section D is newly added and describes recent progress in molecular biology. Briefly, we found that glomalin production is influenced by the host, as shown by host species effects and responses to elevated CO2. We have recently made a significant breakthrough in understanding how glomalin may become deposited into soil; apparently the dominant

    The sonochemical degradation of ethyl paraben (EP), a representative of the parabens family, was investigated. Experiments were conducted at constant ultrasound frequency of 20kHz and liquid bulk temperature of 30°C in the following range of experimental conditions: EP concentration 250-1250μg/L, ultrasound (US) density 20-60W/L, reaction time up to 120min, initial pH 3-8 and sodium persulfate 0-100mg/L, either in ultrapure water or secondary treated wastewater. A factorial design methodology was adopted to elucidate the statistically important effects and their interactions and a full empirical model comprising seventeen terms was originally developed. Omitting several terms of lower significance, a reduced model that can reliably simulate the process was finally proposed; this includes EP concentration, reaction time, power density and initial pH, as well as the interactions (EP concentration)×(US density), (EP concentration)×(pHo) and (EP concentration)×(time). Experiments at an increased EP concentration of 3.5mg/L were also performed to identify degradation by-products. LC-TOF-MS analysis revealed that EP sonochemical degradation occurs through dealkylation of the ethyl chain to form methyl paraben, while successive hydroxylation of the aromatic ring yields 4-hydroxybenzoic, 2,4-dihydroxybenzoic and 3,4-dihydroxybenzoic acids. By-products are less toxic to bacterium V. fischeri than the parent compound. PMID:26964924

  2. Importance of Radiology among the Spanish medical journal dealing with radiodiagnostics: analysis of their production between 1984 and 1993

    International Nuclear Information System (INIS)

    We present a bibliometric analysis of the publications of the journal Radiologia between 1984 and 1993 to contribute to the study of radiodiagnostics reporting in Spain and to determine the importance of Radiologia as a source of information on this subject. We have used the database of the Spanish Medical Index (Indice Medico Espanol, IME) and the journal itself, analyzing the volume, course and distribution of publications on radiodiagnostic procedures. The journal Radiologia publishes 20.1% of the articles dealing with radiology and radiation therapy in Spain. The total number of works was 1,344, that of authors was 2,580 and that of signatures was 6.173, presenting an exponential growth with doubling times of 83.3, 8.5 and 7.4 years, respectively. The analysis shows that the journal's production not only increases over time, but also increments the proportion it contributes to the Spanish medical press as a whole. Radiologia is the most representative journal, in terms of volume of the scientific activity reported in the field of radiodiagnostics in Spain, and its production tends to adapt to the model established for other firmly consolidated scientific and medical disciplines. It alone constitutes the core of the medical journals devoted to radiology and its mean index of circulation according to the IME is 85.79/%. (Author) 34 refs

  4. Association mapping in Scandinavian winter wheat for yield, plant height and traits important for second-generation bioethanol production

    Directory of Open Access Journals (Sweden)

    Andrea eBellucci

    2015-11-01

    Full Text Available A collection of 100 wheat varieties representing more than 100 years of wheat-breeding history in Scandinavia was established in order to identify marker-trait associations for plant height, grain yield and biomass potential for bioethanol production. The field-grown material showed variations in plant height from 54 to 122 cm and in grain yield from 2 to 6.61 t ha-1. The release of monomeric sugars was determined by high-throughput enzymatic treatment of ligno-cellulosic material and varied between 0.169 and 0.312 g/g dm for glucose and 0.146 and 0.283 g/g dm for xylose. As expected, plant height and grain yield showed to be highly influenced by genetic factors with repeatability (R equal to 0.75 and 0.53 respectively, while this was reduced for glucose and xylose (R=0.09 for both . The study of trait correlations showed how old, low-yielding, tall varieties released higher amounts of monomeric sugars after straw enzymatic hydrolysis, showing reduced recalcitrance to bioconversion compared to modern varieties. 93 lines from the collection were genotyped with the DArTseq® genotypic platform and 5525 markers were used for genome-wide association mapping. Six QTLs for grain yield, plant height and glucose released from straw were mapped. One QTL for plant height was previously reported, while the remaining QTLs constituted new genomic regions linked to trait variation. This paper is one of the first studies in wheat to identify QTLs that are important for bioethanol production based on a genome-wide association approach.

  5. Cooperative dialogues during the shift change-over. Importance for the safety and reliability of production systems

    International Nuclear Information System (INIS)

    During shift changeover, verbal communications between operators constitute a means of cooperating in order to continue actions and to carry out the process. The present study was aimed at analyzing verbal exchanges and consequently the role of this work phase. The paper proposes a method of analyzing verbal exchanges This method allows to follow the development of dialogues step by step and enables the operators' representation to be described as the dialogues unfolds. Dialogues observed in two industrial settings (paper manufacturing and nuclear power plant) are analyzed in two complementary ways. The analysis of the content of verbal exchanges (categorization) shows that these exchanges can be very different depending on the work situation (process state, work organization, last shift of the incoming operator...). More precise dialogues analyses show, in some cases, the construction by the operators of a shared functional representation. They consequently emphasize the importance of these exchanges for collective work. The results point out that these exchanges during shift changeover are not only an information transfer allowing actions related to the production process to be continued. They also allow cooperative problem solving and improvement of operators' expertise. On this basis, propositions related to the improvement of this work phase are made. (authors)

    With the stimulator of IFN genes (STING) C terminus being extensively studied, the role of the N-terminal domain (NTD) of STING remains an important subject of investigation. In this article, we identify novel mutations in NTD of Sting of the MOLF strain in response to HSV and Listeria monocytogenes both in vitro and in vivo. These mutations are responsible for low levels of IFN-β caused by failure of MOLF STING to translocate from the endoplasmic reticulum. These data provide evidence that the NTD of STING affects DNA responses via control of trafficking. They also show that the genetic diversity of wild-derived mice resembles the diversity observed in humans. Several human alleles of STING confer attenuated IFN-I production similar to what we observe with the MOLF Sting allele, a crucial functional difference not apparent in classical inbred mice. Thus, understanding the functional significance of polymorphisms in MOLF STING can provide basic mechanistic insights relevant to humans. PMID:26685207

  8. Irradiation of Oil / Water Biphasic Systems: the Importance of Interfacial Surface Area on the Production of Hydrogen and Other Deleterious Products

    International Nuclear Information System (INIS)

    -water interfacial surface area, control of headspace gas composition, and removal of sample aliquots. Results highlight the importance of interfacial surface area in affecting the radiolytic degradation of the studied hydrocarbons. In particular, experiments having higher oil-water interfacial surface areas generate greater quantities of oil degradation products as compared with lower surface area samples. As expected, one notable result from these irradiations was the formation of significant quantities of hydrogen, which was found to be dependent on the interfacial surface area. Presented here is a review of the radiolytic degradation of insoluble organic material in aqueous systems, a summary of experimental results focusing on biphasic systems and a description of a strategy to mitigate the effects of insoluble organic material ingress and to aid in developing station-appropriate responses.

    2009-01-01

    Water is vital to food production: every calorie of plant food requires at least one litre of water, while one calorie of meat or dairy product can require up to 10 litres of water. Water is supplied either through rainfall or through irrigation. Irrigated agriculture uses 18 per cent of agricultural land, and produces 40 per cent of agricultural products. But urbanisation, agricultural land degradation, the mandating of biofuels, drought and climate change are reducing the amount of water available to agriculture. The green revolution of last century doubled cereal production with only a very small increase in land. This century we need a blue revolution, a dramatic increase in the amount of food produced from irrigation or blue water. The blue revolution must be based on knowledge, with that knowledge accessible, and useful, to farmers in both the developed and developing world. PMID:19965339

This makes future production a key question for future social development and this thesis attempts to answer whether it is possible to rely on an assumption of ever increasing production of coal and oil. Both coal and oil are finite resources, created over long time scales by geological processes. It is thus impossible to extract more fossil fuels than geologically available. In other words, there are limits to growth imposed by nature. The concept of depletion and exhaustion of recoverable resources is a fundamental question for the future extraction of coal and oil. Historical experience shows that peaking is a well established phenomenon in production of various natural resources. Coal and oil are no exceptions, and historical data shows that easily exploitable resources are exhausted while more challenging deposits are left for the future. For oil, depletion can also be tied directly to the physical laws governing fluid flows in reservoirs. Understanding and predicting behaviour of individual fields, in particularly giant fields, are essential for understanding future production. Based on comprehensive databases with reserve and production data for hundreds of oilfields, typical patterns were found. Alternatively, depletion can manifest itself indirectly through various mechanisms. This has been studied for coal. Over 60% of the global crude oil production is derived from only around 330 giant oilfields, where many of them are becoming increasingly mature. The annual decline in existing oil production has been determined to be around 6% and it is unrealistic that this will be offset by new field developments, additional discoveries or unconventional oil. This implies that the peak of the oil age is here. For coal a similar picture emerges, where 90% of the global coal production originates

  20. The importance of urea-molasses blocks and bypass protein in animal production: The situation in Pakistan

    International Nuclear Information System (INIS)

    The potential of introducing urea-molasses blocks as a dry season supplementary strategy for domestic ruminants was investigated in several on-farm and on-station experiments. These studies demonstrated the obvious advantage of using the blocks as a farm package to increase milk production in dairy cows and buffaloes and growth rates in calves and lambs under village conditions in Pakistan. Positive responses in productivity to block feeding were attributed to improved rumen efficiency caused by a sustained supply of critical microbial nutrients from continuous licking of the blocks. The studies also confirmed the economic benefits of using the blocks as a complement to conventional concentrates in lactating and growing cows and buffaloes. The need for feeding bypass protein for further increasing animal productivity was also emphasized. The block package was readily accepted by local farmers and was found easy to introduce into the existing on-farm feeding practices in Pakistan. (author). 9 refs, 2 figs, 5 tabs

    Human plasma is an aqueous solution that has to abide by chemical rules such as the principle of electrical neutrality and the constancy of the ionic product for water. These rules define the acid-base balance in the human body. According to the electroneutrality principle, plasma has to be electrically neutral and the sum of its cations equals the sum of its anions. In addition, the ionic product for water has to be constant. Therefore, the plasma concentration of hydrogen ions depends on th...

    Ribosomes are abundant, large RNA–protein complexes that are the source of all protein synthesis in the cell. The production of ribosomes is an extremely energetically expensive cellular process that has long been linked to human health and disease. More recently, it has been shown that ribosome biogenesis is intimately linked to multiple cellular signalling pathways and that defects in ribosome production can lead to a wide variety of human diseases. Furthermore, changes in ribosome production in response to nutrient levels in the diet lead to metabolic re-programming of the liver. Reduced or abnormal ribosome production in response to cellular stress or mutations in genes encoding factors critical for ribosome biogenesis causes the activation of the tumour suppressor p53, which leads to re-programming of cellular transcription. The ribosomal assembly intermediate 5S RNP (ribonucleoprotein particle), containing RPL5, RPL11 and the 5S rRNA, accumulates when ribosome biogenesis is blocked. The excess 5S RNP binds to murine double minute 2 (MDM2), the main p53-suppressor in the cell, inhibiting its function and leading to p53 activation. Here, we discuss the involvement of ribosome biogenesis in the homoeostasis of p53 in the cell and in human health and disease. PMID:27528756

    2015-11-01

    Full Text Available The aim of the study was to answer the following questions: 1. Is the correct valuation of products significant from the point of view of economic risk? 2. Are there situations in Polish practice of inaccurate valuations that lead to material misstatements of financial statements? 3. Is there a risk of inaccurate cost information being used by the management of Polish companies? The review of published materials on the topic has shown that inaccuracies in the calculation of indivi-dual product costs, or overlooking the issue of idle capacity, may increase the economic risk of faulty decisions. A survey conducted among Polish companies has demonstrated that, in many cases, cost accounting does not allow for the accurate calculation of individual product costs or the cost of idle capacity. In addition, the research has highlighted the issue of idle capacity in many Polish companies that hold a significant level of inventories. All of this indicates a risk of distortion in financial statements due to the faulty valua-tion of products in the reports of those companies.

  7. Importance of the in situ production of 36Cl, 36Ar and 14C in hydrology and hydrogeochemistry

    International Nuclear Information System (INIS)

    The paper critically discusses the conditions for the in situ production of 36Cl, 36Ar and 14C. For several confined aquifers in Australia, Canada and North Africa, the 36Cl content (in atoms/L) close to recharge is about one hundred times greater than can be accounted for by reasonable evapotranspiration values. Possible additional sources of 36Cl include cosmic ray irradiation in the shallow unsaturated zone and solutions of rock chloride in environments where the in situ production of 36Cl is large. Dating of old groundwaters with 36Cl should be limited to cases where chlorinity is constant. The age of Cl-, and hence of groundwater, may then be deduced from the decay of the cosmic 36Cl input, or where the groundwater migrates into a U/Th rich environment, from the subsequent ingrowth of 36Cl because of irradiation by the high in situ neutron flux. In the case of 36Ar, after about 1.5 Ma, the accumulation rate of 36Cl is equal to the 36Cl production rate. In the uppermost few metres of continental crust and of the ocean, cosmic ray interactions enhance production by up to several orders of magnitude. Oceanic production amounts to about one-half of the total production. For Cl- rich fluid inclusions in minerals which remained exposed for a long time close to the surface, values of the 36Ar/40Ar ratio may become much higher than the atmospheric value (3.385x10-3). For 14C, in situ production reactions in both the fluid and the rock matrix and the extent to which they may interfere with the use of 14C for groundwater dating have been assessed. The reactions considered include neutron interactions, the exotic decay of radium and α particle reactions. Groundwater of very low alkalinity in high neutron flux environments (e.g. Stripa granite in central Sweden) may gain in situ produced 14C which is equivalent to a few per cent modern carbon.

  13. The tariff equivalent of tariff-rate quotas - A case study applied to the import of an agricultural product in Romania

    Directory of Open Access Journals (Sweden)

    Petru Catalin Bodea

    2008-05-01

    Full Text Available The paper presents one methodology of calculating the tariff equivalent of the tariff-rate quota as a particular case of a non-tariff barrier for an agricultural product imported in Romania based on recommendations in international literature. The tariff equivalent of tariff-rate quota of imports from the EU is approximately 35%, lower than the tariff outside the quota. Nonetheless this is considerable higher when compared with the Common External Tariff (CET. Elimination of the nominal protection level as consequence of the adoption the CET is expected to stimulate imports pressure especially from price competitive import partners both from EU (such as Slovakia, Belgium, Austria, Czech Republic and Italy and non EU countries (Serbia, Bosnia and Herzegovina, Macedonia and Croatia. A basic model forecasts that, with the lowered protection, annual imports will rise with at least 13.5 thousand tonnes, thus an increase of 23% compared with the average annual imports during 1990-2005.

  15. Fast product formation and slow product release are important features in a hysteretic reaction mechanism of glutathione transferase T2-2.

    Jemth, P; Mannervik, B

    1999-08-01

    The reaction mechanism of rat glutathione transferase T2-2 has been studied using pre-steady-state and steady-state kinetics. Several parts of the catalytic cycle including binding of substrates, product formation, and product release were investigated. Under saturating conditions, a two-step product release was found to be rate limiting in the enzyme-catalyzed reactions between the nucleophilic substrate glutathione and either of the two electrophilic substrates 1-menaphthyl sulfate and 4-nitrobenzyl chloride. The rate constant for pre-steady-state product formation on rat glutathione transferase T2-2 has an observed pK(a) value of 5.7 apparently due to ionization of the sulfhydryl group of glutathione. This rate constant is approximately 2 orders of magnitude higher than k(cat) at pH values of >6. It can be predicted from the pH dependence that product formation would be the sole rate-limiting step at pH values of <3. A hysteretic mechanism of rGST T2-2 is proposed based on a slow conformational transition detected in pre-steady-state displacement experiments. PMID:10433705

  16. Spatial decoupling of agricultural production and consumption: quantifying dependences of countries on food imports due to domestic land and water constraints

    International Nuclear Information System (INIS)

    In our globalizing world, the geographical locations of food production and consumption are becoming increasingly disconnected, which increases reliance on external resources and their trade. We quantified to what extent water and land constraints limit countries’ capacities, at present and by 2050, to produce on their own territory the crop products that they currently import from other countries. Scenarios of increased crop productivity and water use, cropland expansion (excluding areas prioritized for other uses) and population change are accounted for. We found that currently 16% of the world population use the opportunities of international trade to cover their demand for agricultural products. Population change may strongly increase the number of people depending on ex situ land and water resources up to about 5.2 billion (51% of world population) in the SRES A2r scenario. International trade will thus have to intensify if population growth is not accompanied by dietary change towards less resource-intensive products, by cropland expansion, or by productivity improvements, mainly in Africa and the Middle East. Up to 1.3 billion people may be at risk of food insecurity in 2050 in present low-income economies (mainly in Africa), if their economic development does not allow them to afford productivity increases, cropland expansion and/or imports from other countries.

  2. The impacts of oil price fluctuations on the economy of sub-Saharan African countries, importers of oil products

    International Nuclear Information System (INIS)

    This work comprises three parts. The first part aims at presenting the energy situation of sub-Saharan African (SSA) countries grouped in five regions. Because of the demographic pressure and of the petroleum shocks, the commercial energy consumption is growing up rapidly and the energy prices are high for the end-users (because the energy is imported and paid in dollars, and the fiscality share is increased by governments in the case of prices drop in the international market). The important problem of wood fuel is considered, together with the energy-economic growth relations and the determining factors of the energy demand in SSA. Some econometric relations are tested. The second part analyzes the mechanisms generated by petroleum shocks and counter-shocks, and stresses first on the transfers induced by these fluctuations. Then, it presents some macro-economical models which try to integrate the effects of a petroleum shock and makes some calculations based on a decomposition of imports and exports global and partial coefficients. Some important conclusions are inferred from this study: 1 - the second petroleum shock strikes more seriously the oil importing SSA countries because they do not benefit from a favorable international context, like during the first shock (also because the second shock is accompanied by a dollar shock); 2 - the absence of symmetry in oil shocks-counter-shocks; 3 - the crisis of SSA countries is not only of petroleum origin but is also linked with the drop of the export incomes (which itself is partially explained by the impact of petroleum shocks on the industrialized economies), with their bad insertion in the world economy, and with unsuitable domestic economies. The third part proposes some solutions to attenuate the energy and economical difficulties of these countries. It is necessary to implement an energy planning mainly based on the mastery of the demand and on a better management of local resources. The policies of

    2003-04-01

    In order to prevent excess sludge production during wastewater treatment, a membrane bioreactor-sludge disintegration (MBR-SD) system has been introduced, where the disintegrated sludge is recycled to the bioreactor as a feed solution. In this study, a mathematical model was developed by incorporating a sludge disintegration term into the conventional activated sludge model and the relationships among the operational parameters were investigated. A new definition of F/M ratio for the MBR-SD system was suggested to evaluate the actual organic loading rate. The actual F/M ratio was expected to be much higher than the apparent F/M ratio in MBR-SD. The kinetic parameters concerning the biodegradability of organics hardly affect the system performance. Instead, sludge solubilization ratio (alpha) in the SD process and particulate hydrolysis rate constant (k(h)) in biological reaction determine the sludge disintegration number (SDN), which is related with the overall economics of the MBR-SD system. Under reasonable alpha and k(h) values, SDN would range between 3 and 5 which means the amount of sludge required to be disintegrated would be 3-5 times higher for preventing a particular amount of sludge production. Finally, normalized sludge disintegration rate (q/V) which is needed to maintain a certain level of MLSS in the MBR-SD system was calculated as a function of F/V ratio. PMID:12697235

This is causing a global food crisis. The production of ethanol from corn is emerging as an alternative that may address global warming and attacking the alleged shortage of oil, which has resulted in rising prices. The point in discussion is what are the possible effects of policies to induce the production of biofuels (ethanol on the main importers of corn. That’s why the current status of the ethanol industry is analyzed, whose main protagonists on the world stage are the United States and Brazil. Then we made a brief analysis of the market of corn. Finally, based on the foregoing, we reflect on the possible implications it might have on the development of food production of etanol.

  7. The importance of urea-molasses blocks and bypass protein in animal production: The situation in tropical Latin America

    International Nuclear Information System (INIS)

    The grasslands of Latin America sustain 25% of the world cattle population. Most of the cattle are located in tropical Latin America. There are two predominant systems of production, dual purpose and beef, with diets based primarily on cultivated or native pastures and to a minor extent on conserved feeds and fibrous agricultural by-products. Urea-molasses blocks and bypass protein supplements are recently introduced technologies that could contribute to solution of some of the feeding constraints of the systems. The use of bypass protein has been mainly studied using fish meal as a supplement to medium quality basal feeds. Large live weight gain responses have been obtained with growing animals, but the influence on milk yield of dual purpose animals is small or non-existent. Supplements with fish meal offered once a day did not increase the utilization of basal fibrous diets in the rumen and were not able to sustain adequate levels of ammonia nitrogen throughout the day. Lower responses have been obtained with other bypass protein sources. The use of urea-molasses blocks has been investigated less. The major impact of this technology should be in extensive grazing systems with diets based on native pastures low in nitrogen. The scarce evidence available indicates that the sporadic consumption of blocks in these conditions prevents them from fulfilling the main objective, which is to provide a constant source of degradable nitrogen throughout the day. But there is still a positive effect on live weight change and reproduction during the dry season. The blocks should be adapted to this situation by incorporation of sources of slow nitrogen release.

  8. Slow and fast pyrolysis of Douglas-fir lignin: Importance of liquid-intermediate formation on the distribution of products

    International Nuclear Information System (INIS)

    The formation of liquid intermediates and the distribution of products were studied under slow and fast pyrolysis conditions. Results indicate that monomers are formed from lignin oligomeric products during secondary reactions, rather than directly from the native lignin. Lignin from Douglas-fir (Pseudotsuga menziesii) wood was extracted using the milled wood enzyme lignin isolation method. Slow pyrolysis using a microscope with hot-stage captured the liquid formation (>150 °C), shrinking, swelling (foaming), and evaporation behavior of lignin intermediates. The activation energy (Ea) for 5–80% conversions was 213 kJ mol−1, and the pre-exponential factor (log A) was 24.34. Fast pyrolysis tests in a wire mesh reactor were conducted (300–650 °C). The formation of the liquid intermediate was visualized with a fast speed camera (250 Hz), showing the existence of three well defined steps: formation of lignin liquid intermediates, foaming and liquid intermediate swelling, and evaporation and droplet shrinking. GC/MS and UV-Fluorescence of the mesh reactor condensate revealed lignin oligomer formation but no mono-phenols were seen. An increase in pyrolytic lignin yield was observed as temperature increased. The molar mass determined by ESI-MS was not affected by pyrolysis temperature. SEM of the char showed a smooth surface with holes, evidence of a liquid intermediate with foaming; bursting from these foams could be responsible for the removal of lignin oligomers. Py-GC/MS studies showed the highest yield of guaiacol compounds at 450–550 °C. - Highlights: • The formation of a liquid intermediate phase is a critical step during lignin pyrolysis. • The lignin oligomers are thermally ejected from the liquid intermediate phase. • The mono-phenols are formed mainly from the secondary reactions of lignin oligomers

    Aspartate kinase (AK) is an enzyme which is tightly regulated through feedback control and responsible for the synthesis of 4-phospho-L-aspartate from L-aspartate. This intermediate step is at an important branch point where one path leads to the synthesis of lysine and the other to threonine, methionine and isoleucine. Concerted feedback inhibition of AK is mediated by threonine and lysine and varies between the species. The crystal structure of biotechnologically important Clostridium acetobutylicum aspartate kinase (CaAK; E.C. 2.7.2.4; Mw=48,030Da; 437aa; SwissProt: Q97MC0) has been determined to 3Å resolution. CaAK acquires a protein fold similar to the other known structures of AKs despite the low sequence identity (Clostridium tetani (64% sequence identity) suggesting the potential of the structure solved here to be applied for modeling drug interactions. CaAK structure may serve as a guide to better understand and engineer lysine biosynthesis for the biotechnology industry. PMID:25170437

  10. THE PRODUCTION OF LOW-ENERGY NEUTRONS IN SOLAR FLARES AND THE IMPORTANCE OF THEIR DETECTION IN THE INNER HELIOSPHERE

    International Nuclear Information System (INIS)

    Neutron detectors on spacecraft in the inner heliosphere can observe the low-energy (ion –1) most important for producing low-energy neutrons from these reactions. We calculate escaping-neutron spectra and neutron-capture line yields from ions propagating in a magnetic loop with various kinetic-energy spectra. This study provides the basis for planning inner-heliospheric missions having a low-energy neutron detector. The MESSENGER spacecraft orbiting Mercury has such a detector. We conclude that a full understanding of ion acceleration, transport, and interaction at the Sun requires observation of both neutrons and gamma rays with detectors of comparable sensitivity. We find that the neutron-capture line fluence at 1 AU is comparable to the 1-10 MeV neutron fluence at 0.5 AU, and therefore as effective for revealing low-energy ion acceleration. However, as the distance from the Sun to the neutron detector decreases, the tremendous increase of the low-energy neutron flux allows exploration of ion acceleration in weak flares not previously observable and may reveal acceleration at other sites not previously detected where low-energy neutrons could be the only high-energy signature of ion acceleration. Also, a measurement of the low-energy neutron spectrum will provide important information about the accelerated-ion spectrum that is not available from the capture line fluence measurement alone.

    In the present study, we employed a DNA barcoding approach to authenticate the species of fish imported via one port in China. The fish were identified as smallmouth scad based on morphological characteristics, Alepes apercna (Perciformes, Carangidae), but were labeled as Rastrelliger brachysoma (Perciformes, Scombridae). Fragments of the partial mitochondrial cytochrome c oxidase 1 (COI) gene were sequenced from 12 specimens, and their phylogenetic relationship was subsequently examined. The phylogenetic analysis demonstrated that all of the individuals formed a monophyletic cluster with high bootstrap values and were placed in a sister group with the ancestor of Alepes vari and Alepes melanoptera. The K2P genetic distances at an intraspecific level were significantly smaller than those at an interspecific level. Our results indicated that the fish were A. apercna, rather than R. brachysoma, which confirms the morphological analysis. This study presents a practical demonstration of the use of DNA barcoding to prevent fraud in international trade. PMID:26920274

    Full Text Available Aspartate kinase (AK is an enzyme which is tightly regulated through feedback control and responsible for the synthesis of 4-phospho-l-aspartate from l-aspartate. This intermediate step is at an important branch point where one path leads to the synthesis of lysine and the other to threonine, methionine and isoleucine. Concerted feedback inhibition of AK is mediated by threonine and lysine and varies between the species. The crystal structure of biotechnologically important Clostridium acetobutylicum aspartate kinase (CaAK; E.C. 2.7.2.4; Mw = 48,030 Da; 437aa; SwissProt: Q97MC0 has been determined to 3 Å resolution. CaAK acquires a protein fold similar to the other known structures of AKs despite the low sequence identity (<30%. It is composed of two domains: an N-terminal catalytic domain (kinase domain and a C-terminal regulatory domain further comprised of two small domains belonging to the ACT domain family. Pairwise comparison of 12 molecules in the asymmetric unit helped to identify the bending regions which are in the vicinity of ATP binding site involved in domain movements between the catalytic and regulatory domains. All 12 CaAK molecules adopt fully open T-state conformation leading to the formation of three tetramers unique among other similar AK structures. On the basis of comparative structural analysis, we discuss tetramer formation based on the large conformational changes in the catalytic domain associated with the lysine binding at the regulatory domains. The structure described herein is homologous to a target in wide-spread pathogenic (toxin producing bacteria such as Clostridium tetani (64% sequence identity suggesting the potential of the structure solved here to be applied for modeling drug interactions. CaAK structure may serve as a guide to better understand and engineer lysine biosynthesis for the biotechnology industry.

    Limnologists recently have developed an interest in quantifying benthic resource contributions to higher-level consumers. Much of this research focuses on natural lakes with very little research in reservoirs. In this study, we provide a contemporary snapshot of the food web structure of Lake Mead to evaluate the contribution of benthic resources to fish consumers. In addition, we document the available food to fishes on soft sediments and changes to the invertebrate community over 2 time periods. Benthic invertebrate food availability for fishes is greater in Las Vegas Bay than Overton Arm. Las Vegas Bay is dominated by oligochaetes, whose biomass increased with depth, while Overton Arm is dominated by chironomids, whose biomass did not change with depth. Diet and isotopic measurements indicate the fish community largely relies on benthic resources regardless of basin (Las Vegas Bay >80%; Overton Arm >92%); however, the threadfin shad likely contribute more to largemouth and striped bass production in Overton Arm versus Las Vegas Bay. A 2-time period analysis, pre and post quagga mussel establishment and during lake level declines, suggests there is no change in the density of benthic invertebrates in Boulder Basin, but there were greater abundances of select taxa in this basin by season and depth than in other basins. Given the potential of alterations as a result of the expansion of quagga mussel and the reliance of the fishery on benthic resources, future investigation of basin specific, benthic processes is recommended.

    Recurrent coastal upwelling is recognized as one of the main factors promoting the exceptionally high productivity of the Humboldt Current System. Herein, we study time series data of gross primary production (2003-2006) and its fluctuation in relation to seasonal changes in the light and nutrient field of the Concepción upwelling ecosystem. Concurrent measurements of gross primary production, community respiration, bacterial secondary production, and sedimentation rates allowed a characterization of the main carbon fluxes and pathways in the study area. The integrated values of gross primary production were higher during the upwelling period (>1 g C m -2 d -1; October-April; that is, early spring to early austral fall). Seasonal changes in the system were also reflected in community respiration, organic matter sedimentation, and bacterial production rates, which varied along with the gross primary production. The significant correlation between gross primary production and community respiration (Spearman, r = 0.7; p 6 g C m -2 d -1) were consistently associated with maximum biomass levels of Skeletonema costatum and Thalassiosira subtilis. We observed a positive correlation between gross primary production and the sedimentation of intact diatom cells (Spearman, r = 0.5, p < 0.05, n = 17). Our data suggest that, in the Concepción upwelling ecosystem, bacteria utilize an important fraction of the gross primary production. If our interpretations are correct, they leave unanswered the question of how the system supports the extremely high fish biomass levels, therein pointing out the system’s limited capacity to buffer the evasion of CO 2 following upwelling.

  15. The importance of urea-molasses blocks and bypass protein in animal production: The situation in Bangladesh

    International Nuclear Information System (INIS)

    Molasses remains underutilized as an animal feed in Bangladesh. Urea and molasses are used for supplementation of fibrous feeds in many countries. Used in sprayed form on straw or in liquid form, urea-molasses caused practical problems in village farming conditions owing to urea toxicity from higher intake by livestock, as well as difficulties in handling, storage and transport to remote villages. To overcome these problems and to produce a supply of easily available energy and nitrogen to ruminants, a simple method has been developed for making urea-molasses blocks with locally available ingredients and equipment at the farm level in the villages. To evaluate the nutritional potential of urea-molasses blocks fed to livestock on a straw based diet, a study has been conducted on the performance of livestock under on-farm conditions. Results from experiments on the nutritional value of the block are reported. Daily live weight gain, milk yield and draught output of cattle increased significantly. A similar positive response in the performance of sheep and goats was also observed. Once the supply of rumen fermentable nitrogen and energy is ensured to optimize the rate of degradation of fibrous substrate with supplementation of urea-molasses block lick, the next limitation to production is the availability of amino acids absorbed from the intestine. To overcome this limitation, protein with a low rate of degradation, such as fish meal, could be used as bypass protein. Several experiments were conducted on the effect of supplementation of bypass protein on the performance of cattle, sheep and goats in both on-station and on-farm conditions. Results indicated a positive response in daily live weight gain, milk yield and draught power output. 31 refs, 6 figs, 6 tabs

    The silkworm middle silk gland (MSG) is the sericin synthesis and secretion unique sub-organ. The molecular mechanisms of regulating MSG protein synthesis are largely unknown. Here, we performed shotgun proteomic analysis on the three MSG subsections: the anterior (MSG-A), middle (MSG-M), and posterior (MSG-P) regions. The results showed that more strongly expressed proteins in the MSG-A were involved in multiple processes, such as silk gland development and silk protein protection. The proteins that were highly expressed in the MSG-M were enriched in the ribosome pathway. MSG-P proteins with stronger expression were mainly involved in the oxidative phosphorylation and citrate cycle pathways. These results suggest that the MSG-M is the most active region in the sericin synthesis. Furthermore, comparing the proteome of the MSG with the posterior silk gland (PSG) revealed that the specific and highly expressed proteins in the MSG were primarily involved in the ribosome and aminoacyl-tRNA biosynthesis pathways. These results indicate that silk protein synthesis is much more active as a result of the enhancement of translation-related pathways in the MSG. These results also suggest that enhancing ribosome biogenesis is important to the efficient synthesis of silk proteins. PMID:26051239

    2013-05-01

    Full Text Available This paper analyses consumer preferences for different eggs attributes to assess the importance placed by consumers on the origin and method of production when shopping. The data comes from an experiment conducted in Spain during 2009. An Error Component Random Parameter Logit model is used to estimate the effect of different eggs characteristics on consumers’ utility and derive their willingness to pay. Results suggest that consumers positively value the free-range and organic method of production and the local and regional origin and that they are willing to pay an additional € 0.85 for each package of six free-range or organic eggs, € 0.77 for locally produced and € 0.27 for regional produced eggs. Hence, the least valued eggs for consumers are those produced in cages and outside the region. Relative to this product, the highest willingness to pay corresponds to free-range or organic eggs followed by locally produced eggs and finally, by the regional eggs. Thus, we can conclude that Spanish consumers give more importance when shopping for eggs to the method of production than to the origin of production.

  20. The Byzantine ceramics from Pergamon excavations. Characterization of local and imported productions by elementary analysis using PIXE and INAA methods and by petrography

    International Nuclear Information System (INIS)

    An important ceramics material dated back to the 12th-14th centuries has been excavated in Pergamon (Turkey). Among these findings, wasters, tripod stilts and unfinished ware attest to local production in the Byzantine period. Elemental analysis by the methods PIXE (Particle Induced X-ray Emission) and INAA (Instrumental Neutron Activation Analysis) has been performed on a representative sampling of 160 sherds, including attested local material. Multivariate statistical techniques were used to classify the sherds into groups of similar composition and thus to distinguish ceramics made in Pergamon from imported wares. Several groups of local production have been constituted, which correspond to wares differing in date and fabric. The geochemical characterization of the pastes, complemented with petrographical and mineralogical data, shows that specific raw materials have been used to manufacture each ware. The analytical data related to ceramics made in Pergamon will serve as reference data for future provenance studies. Such reference groups of Byzantine ceramics are very rare, and therefore the ceramics imported into Pergamon cannot be attributed as to their origin. Among the ceramics widely diffused in the Byzantine world, some importations belonging to the ''fine sgraffito'' and ''Zeuxippus ware'' types have been identified. The latter type has been a source of stylistic influence for the workshops of Pergamon, since the analyses show that imitated ''Zeuxippus ware'' has been produced there. These imitations were probably themselves diffused on a regional scale. (author). 238 refs., 48 figs., 53 tabs., 22 photos., 8 appends

    In the present paper the Natvig measures of component importance for repairable systems, and its extended version are analyzed for two three-component systems and a bridge system. The measures are also applied to an offshore oil and gas production system. According to the extended version of the Natvig measure a component is important if both by failing it strongly reduces the expected system uptime and by being repaired it strongly reduces the expected system downtime. The results include a study of how different distributions affect the ranking of the components. All numerical results are computed using discrete event simulation.

    Full Text Available The goal of the paper was the analysis of Romania’s the agro-food export, import and trade balance by the EU country group and agro-food product group based on the statistical data in the year 2010 in order to identify the commercial relationships with a positive and respectively a negative impact of the trade balance. The EU trade partners were divided into 4 groups: Central Eastern (CE, Western (W, Northern (N and Southern (S EU countries and the agro-food product groups were: Live animals and preparations of animal origin, Vegetal products, Fats and oils of vegetal and animal origin, Food, beverages and tobacco. The data were processed using the share and comparison methods. In 2010, Romania registered a negative agro-food trade balance with a deficit of Euro thousand 903,148.This was due to the unefficient commerce with the CE and W EU countries, which together recorded Euro Thousand 1,400,298 deficit. The balance was positively influenced by the Southern EU trade partners whose contribution accounted for Euro thousand 513,953. Therefore, the agro-food trade has to be intensified with the Southern EU countries and to become more relaxed with the CE and W EU countries, especially regarding imports. Live animals are mainly required in the CE and W EU countries, vegetal products in the W and S EU countries, fats and oils in the CE and S EU countries, and finally, food, beverages and tobacco in the S and the CE EU countries. Agro-food imports have to be substantially diminished as long as Romania’ s agriculture is able to produce for the internal market and export has to be intensified especially with the countries with a positive impact on the trade balance.

    1. Lakes Michigan and Huron, which are undergoing oligotrophication after reduction of phosphorus loading, invasion by dreissenid mussels and variation in climate, provide an opportunity to conduct large-scale evaluation of the relative importance of these changes for lake productivity. We used remote sensing, field data and an information-theoretic approach to identify factors that showed statistical relationships with observed changes in chlorophyll a (chla) and primary production (PP). 2. Spring phosphorus (TP), annual mean chla and PP have all declined significantly in both lakes since the late 1990s. Additionally, monthly mean values of chla have decreased in many but not all months, indicating altered seasonal patterns. The most striking change has been the decrease in chla concentration during the spring bloom. 3. Mean chlorophyll a concentration was 17% higher in Lake Michigan than in Lake Huron, and total production for 2008 in Lake Michigan (9.5 tg year 1 ) was 10% greater than in Lake Huron (7.8 tg year 1 ), even though Lake Michigan is slightly smaller (by 3%) than Lake Huron. Differences between the lakes in the early 1970s evidently persisted to 2008. 4. Invasive mussels influenced temporal trends in spring chla and annual primary production. However, TP had a greater effect on chla and primary production than did the mussels, and TP varied independently from them. Two climatic variables (precipitation and air temperature in the basins) influenced annual chla and annual PP, while the extent of ice cover influenced TP but not chla or primary production. Our results demonstrate that observed temporal patterns in chla and PP are the result of complex interactions of P, climate and invasive mussels.

    2014-07-01

    Full Text Available Designations of origin (DOs are commercial brands of wide use in the agro-food sector. Its use in Spain has taken place for more than three decades and although wineries managers have incorporated these new forms of protection, little is known about their opinion and their point of view during the DO implementation process. In fact, the consumers’ point of view has been the one most often analyzed in the literature. In the present study we analyzed extrinsic attributes of a wine with DO from the company point of view. In particular, we analyzed brand, product, price, packaging and label, and origin of the product following a qualitative analysis on interviews carried out with winemakers of the DO wine Ribera del Guadiana during the last decade. The qualitative analysis of the interviews was performed using the software package ATLAS/ti, designed for this type of data analysis in the form of large blocks of text. The results indicated that winemakers consider that they offer a good product to the market, and try to promote their brands using the origin of the product as a marketing strategy. From the company point of view, this protected DO (PDO has important opportunities for positioning to create a sustainable competitive advantage, focusing on quality and the territorial differentiation.

    Full Text Available The present study had as objective to characterize aspects of the attainment and commercialization of the Brazilian-pine nut, as a resource capable to contribute for attainment of income and conservation of FOM. For this, studies were carried out aiming at: checking Brazilian-pine production on a natural population (RGFC – Genetic and Forest Reserve of Caçador and on a reforestation with Brazilian-pine (Flona- Caçador’s National Florest; identifying the profile of the Brazilian-pine nut’s collectors in the District of Taquara Verde, Caçador-SC – its knowledge about the resource and the importance of this resource as an income source. For this, 36 female Brazilian-pines were target in Flona and 25 in RGFC. Brazilian-pine nut production was estimated based on the number of female plants, number of cones per plant, number of nut per cone and nut weight. To the other objectives, interviews with the nut’s collectors were made. The production found at RGFC was 44.3kg.ha-1 and at Flona was 24.6kg.ha-1, the difference was attributed to the higher density found at Flona. About the importance of Brazilian-pine nut to the community, it could be found out that this resource is very important both as an income source and food, allowing us to separate the collectors in four kinds of profile. The families which were more dependent on this resource as income, more often they collect and more people in the family are involved in the collection of the Brazilian-pine nut, but not necessary they know more about it. The results of this study indicate a good potential of this resource to increase the household of poor communities, emphasizing the importance of natural areas to the exploration of Brazilian-pine nut and bringing subsidies for the establishment of politics that can effectively join a valuation of the forest resources, the communities’ development together with nature conservation.

    This research aimed to monitor the concentrations of sulfamethoxydiazine (SMD), sulfamethazine (SMT), sulfamethoxazole (SMX) and sulfadiazine (SDZ) in imported Pangasius catfish products in Thailand. The residues of the four sulfonamides (SAs) were analyzed by extraction process and liquid chromatography coupled with tandem mass spectrometry. The highest concentrations found were 10.97ng/g for SMD, 6.23ng/g for SMT, 11.13ng/g for SDZ and 245.91ng/g for SMX, which was higher than the European Union (EU) standard (100ng/g). Moreover, all samples contaminated with SMX also contained SMT, indicating that more than one antibiotic was used for production in the country of origin. Because Thai standards for antibiotics in food have not been completely set, all contaminated discovered would not be considered to be an illegal food, in which antibiotic residues may affect human health in the long term. Therefore, antibiotic residues in Pangasius catfish products should be continually regulated and monitored. PMID:27374578

    We measured a large suite of gas- and particle-phase multi-functional organic compounds with a Filter Inlet for Gases and AEROsols (FIGAERO) coupled to a high-resolution time-of-flight chemical ionization mass spectrometer (HR-ToF-CIMS) developed at the University of Washington. The instrument was deployed on environmental simulation chambers to study monoterpene oxidation as a secondary organic aerosol (SOA) source. We focus here on results from experiments utilizing an ionization method most selective towards acids (acetate negative ion proton transfer), but our conclusions are based on more general physical and chemical properties of the SOA.

    Helicoerpa armigera nucleopolyhedrovirus (HearNPV) ha83 is a late expressed gene that encodes a chitin binding protein. Chitin domain truncation studies revealed that the cysteine at the 128 amino acid position probably played an important role in both chitin binding ability and protein transmission of Ha83. In order to study the function of ha83 in the HearNPV infection cycle, an ha83 knockout HearNPV (Ha83KO) was constructed via homologous recombination. Viral growth and viral DNA replication curves showed that fewer budded virions were produced in Ha83KO transfected cells, while viral DNA replication was increased. Electron microscopy revealed that fewer nucleocapsids were transmitted from virogenic stroma in the Ha83KO transfected cell nucleus, and the morphology of occlusion bodies was prominently larger and cube-shaped. Furthermore, DNA quantity in occlusion bodies of Ha83KO was significantly lower than the occlusion bodies of HaWT. The transcription analysis indicated that these changes may be due to the decreased expression level of viral structural associated genes, such as polyhedrin, p10, pif-2, or cg30 in Ha83KO infected cells. Above results demonstrated that the cysteine at the 128 amino acid position in Ha83 might be the key amino acid, and Ha83 plays an important role in BVs production and OBs assembling. PMID:26057202

    During the analysis of a Customs' importation case for the suspected presence of controlled drugs, amphetamine was found to be present. The samples were also found to contain by-products from the amphetamine synthesis and these included benzyl cyanide, phenylacetone (P2P), methyl-phenyl-pyrimidines, N-formylamphetamine, a pair of naphthalene derivatives and amphetamine dimers. During the experimental investigation of the naphthalenes formation, a series of syntheses involved the acid hydrolysis of α-phenylacetoacetonitrile (APAAN). In one such experiment with sulfuric acid, a white substance was visibly deposited on the glassware and this was identified as the pyridone derivative, 4,6-dimethyl-3,5-diphenylpyridin-2-one. This compound was subsequently found to be present in the amphetamine product seized by the Customs and also in the final product of our own laboratory synthesized amphetamine (APAAN hydrolyzed to P2P/Leuckart reaction). Interestingly, the, 4,6-dimethyl-3,5-diphenylpyridin-2-one was not found when commercially supplied P2P underwent the Leuckart reaction to yield amphetamine. This suggests that 4,6-dimethyl-3,5-diphenylpyridin-2-one may be a route specific marker to the use of APAAN as a starting material in the synthesis of P2P and subsequent Leuckart reaction to yield amphetamine.

  18. Why is seed production so variable among individuals? A ten-year study with oaks reveals the importance of soil environment.

    Directory of Open Access Journals (Sweden)

    Ignacio M Pérez-Ramos

    Full Text Available Mast-seeding species exhibit not only a large inter-annual variability in seed production but also considerable variability among individuals within the same year. However, very little is known about the causes and consequences for population dynamics of this potentially large between-individual variability. Here, we quantified seed production over ten consecutive years in two Mediterranean oak species - the deciduous Quercus canariensis and the evergreen Q. suber - that coexist in forests of southern Spain. First, we calibrated likelihood models to identify which abiotic and biotic variables best explain the magnitude (hereafter seed productivity and temporal variation of seed production at the individual level (hereafter CVi, and infer whether reproductive effort results from the available soil resources for the plant or is primarily determined by selectively favoured strategies. Second, we explored the contribution of between-individual variability in seed production as a potential mechanism of satiation for predispersal seed predators. We found that Q. canariensis trees inhabiting moister and more fertile soils were more productive than those growing in more resource-limited sites. Regarding temporal variation, individuals of the two studied oak species inhabiting these resource-rich environments also exhibited larger values of CVi. Interestingly, we detected a satiating effect on granivorous insects at the tree level in Q. suber, which was evident in those years where between-individual variability in acorn production was higher. These findings suggest that individual seed production (both in terms of seed productivity and inter-annual variability is strongly dependent on soil resource heterogeneity (at least for one of the two studied oak species with potential repercussions for recruitment and population dynamics. However, other external factors (such as soil heterogeneity in pathogen abundance or certain inherent characteristics of the

  19. US Oil import dependency

    International Nuclear Information System (INIS)

    After declining oil imports in the US in the first half of the 1980's, the trend is reversed since 1986; the world oil price collapse of 1986 was obviously a major factor in the US import rise. However, it may just have expedited a trend that was already in the making rather than started a new. The growing import dependence have evident impacts on the balance of trade (but not so important), on encouraging domestic production against supply disruption for example, and on environmental policies

    In Senegal, a project has been undertaken to eradicate a population of tsetse flies (Glossina palpalis gambiensis) from a prime area for intensifying livestock production--the coastal region of Niayes. The project is intended to remove the constraint of trypanosomosis and allow the ecological intensification of cattle production. A cross-sectional analysis of ten case studies was the inductive phase of an assessment to gauge the impact of removing trypanosomosis on livestock production strategies. The methodology used was comprehensive analysis, with participatory epidemiology tools to understand farmers' rationales. The authors analysed the strategies of three main types of livestock producer (agro-pastoralists, mixed crop/livestock farmers and intensive dairy farmers). The strategies were in line with the farmers' goals and their ability to mobilise the socio-technical network. The risk management of trypanosomosis has been incorporated into livestock management practices through the use of trypanotolerant breeds, medical prophylaxis or placing livestock in low-risk areas. Removing the risk of disease would therefore have a major impact on decisions about the composition and strategic direction of herds. This change in the animal health environment would steer livestock production along different routes of intensification in a highly competitive environment. The indicators of innovation capacity revealed by this study will be used to quantitatively monitor various change scenarios, taking livestock producers' reasoning into account, in order to assess the socio-economic impact of eradicating the tsetse fly population in this area. The methodology presented in the study can be used to understand the impact of controlling other vector-borne infections on the innovation dynamics of livestock producers. PMID:26470458

    Light is one of the key elicitors that directly fluctuates plant developmental processes and biosynthesis of secondary metabolites. In this study, the effects of various spectral lights on biomass accumulation and production of antioxidant secondary metabolites in callus cultures of Prunella vulgaris were investigated. Among different spectral lights, green light induced the maximum callogenic response (95%). Enhanced fresh biomass accumulation was observed in log phases on day-35, when callus cultures were exposed to yellow and violet lights. Yellow light induced maximum biomass accumulation (3.67g/100ml) from leaf explants as compared to control (1.27g/100ml). In contrast, violet lights enhanced biomass accumulation (3.49g/100ml) from petiole explant. Maximum total phenolics content (TPC; 23.9mg/g-DW) and total flavonoids content (TFC; 1.65mg/g-DW) were observed when cultures were grown under blue lights. In contrast, green and yellow lights enhanced total phenolics production (TPP; 112.52g/100ml) and total flavonoids production (TFP; 9.64g/100ml) as compared to control. The calli grown under green, red and blue lights enhanced DPPH-free radical scavenging activity (DFRSA; 91.3%, 93.1% and 93%) than control (56.44%) respectively. The DFRSA was correlated either with TPC and TFC or TPP and TFP. Furthermore, yellow lights enhanced superoxide dismutase (SOD), peroxidase (POD) and protease activities, however, the content of total protein (CTP) was higher in control cultures (186μg BSAE/mg FW) as compared to spectral lights. These results suggest that the exposure of callus cultures to various spectral lights have shown a key role in biomass accumulation and production of antioxidant secondary metabolites. PMID:26995670

  9. Transcription factor σB plays an important role in the production of extracellular membrane-derived vesicles in Listeria monocytogenes.

    Directory of Open Access Journals (Sweden)

    Jung Hwa Lee

    Full Text Available Gram-negative bacteria produce extracellular outer membrane vesicles (OMVs that interact with host cells. Unlike Gram-negative bacteria, less is known about the production and role of extracellular membrane vesicles (MVs in Gram-positive bacteria. The food-borne pathogen Listeria monocytogenes can survive under extreme environmental and energy stress conditions and the transcription factor σ(B is involved in this survival ability. Here, we first determined the production of MVs from L. monocytogenes and evaluated whether general stress transcription factor σ(B affected production of MVs in L. monocytogenes. L. monocytogenes secreted MVs during in vitro broth culture. The wild-type strain actively produced MVs approximately nine times more and also produced more intact shapes of MVs than those of the isogenic ΔsigB mutant. A proteomic analysis showed that 130 and 89 MV proteins were identified in the wild-type and ΔsigB mutant strains, respectively. Wild-type strain-derived MVs contained proteins regulated by σ(B such as transporters (OpuCA and OpuCC, stress response (Kat, metabolism (LacD, translation (InfC, and cell division protein (FtsZ. Gene Ontology (GO enrichment analysis showed that wild-type-derived MV proteins corresponded to several GO terms, including response to stress (heat, acid, and bile resistance and extracellular polysaccharide biosynthetic process, but not the ΔsigB mutant. Internalin B (InlB was almost three times more contained in MVs derived from the wild-type strain than in MVs derived from the ΔsigB mutant. Taken together, these results suggest that σ(B plays a pivotal role in the production of MVs and protein profiles contained in MVs. L. monocytogenes MVs may contribute to host infection and survival ability under various stressful conditions.

    In terrestrial high-latitude regions, observations indicate recent changes in snow cover, permafrost, and soil freeze-thaw transitions due to climate change. These modifications may result in temporal shifts in the growing season and the associated rates of terrestrial productivity. Changes in productivity will influence the ability of these ecosystems to sequester atmospheric CO2. We use the terrestrial ecosystem model (TEM), which simulates the soil thermal regime, in addition to terrestrial carbon (C), nitrogen and water dynamics, to explore these issues over the years 1960-2100 in extratropical regions (30-90??N). Our model simulations show decreases in snow cover and permafrost stability from 1960 to 2100. Decreases in snow cover agree well with National Oceanic and Atmospheric Administration satellite observations collected between the years 1972 and 2000, with Pearson rank correlation coefficients between 0.58 and 0.65. Model analyses also indicate a trend towards an earlier thaw date of frozen soils and the onset of the growing season in the spring by approximately 2-4 days from 1988 to 2000. Between 1988 and 2000, satellite records yield a slightly stronger trend in thaw and the onset of the growing season, averaging between 5 and 8 days earlier. In both, the TEM simulations and satellite records, trends in day of freeze in the autumn are weaker, such that overall increases in growing season length are due primarily to earlier thaw. Although regions with the longest snow cover duration displayed the greatest increase in growing season length, these regions maintained smaller increases in productivity and heterotrophic respiration than those regions with shorter duration of snow cover and less of an increase in growing season length. Concurrent with increases in growing season length, we found a reduction in soil C and increases in vegetation C, with greatest losses of soil C occurring in those areas with more vegetation, but simulations also suggest that

  12. Purification and characterization of a furfural reductase (FFR) from Escherichia coli strain LYO1--an enzyme important in the detoxification of furfural during ethanol production.

    Gutiérrez, Tony; Ingram, Lonnie O; Preston, James F

    2006-01-24

    Furfural, an inhibitor of ethanol production from hemicellulose acid hydrolysates, is reductively detoxified to furfuryl alcohol by the ethanologenic bacterium Escherichia coli strain LYO1. Furfural reductase was purified 106-fold from this bacterium to approximately 50% homogeneity. It has a native molecular mass of 135 kDa, determined by gel filtration, and subunit molecular mass of approximately 68 kDa, determined by denaturing gel electrophoresis, indicating the holoenzyme is a dimer of two similar if not identical subunits. The enzyme shows strong activity from pH 4 to 8 (optimum pH 7.0), relatively high temperature tolerance (50-55 degrees C), and an apparent Km and Vmax for furfural of 1.5x10(-4)M and 28.5 micromol/min/mg of protein, respectively. It catalyzes the essentially irreversible reduction of furfural with NADPH, is specific for NADPH as cofactor, and is relatively specific for the reduction of furfural and benzaldehyde; 2-acetylfuran, xylose, and glucose were not reduced, while acetaldehyde was reduced at a rate 25-fold lower than furfural. This is the first description of a furfural reductase which, based upon size and substrate specificity, appears to represent a new type of alcohol-aldehyde oxido-reductase. The conversion of relatively toxic furfural to less toxic furfuryl alcohol suggests a beneficial role for this enzyme in mitigating furfural toxicity encountered during ethanol production from lignocellulosic biomass.

    To pre-establish an alternative technique to the toxic fumigant, methyl bromide which is the current quarantine measure of agricultural products for export, some selected agricultural products, such as apple and pear, were subjected to a preliminary study to confirm the comparative effects of gamma irradiation and MeBr fumigant on their disinfestation and quality, thereby preparing the basic data for the practical approach. Current quarantine activities were examined and the related limitations were investigated. Quarantine-related pests were investigated on their radiosensitivity and disinfestation effects by both treatments. The pests in apple and pear, Tetranychus urticae Koch, Panonychus ulmis Koch revealed a 100% mortality at around 17 days after irradiation of 3 kGy but it was too high dose for apple and pear. Tetranychus urticae Koch, Panonychus ulmi Koch from both apple and pear showed an increased mortality when exposed to 1 {approx} 2 kGy irradiation, resulting in apparent mortality 1 month later. 1 {approx} 2 kGy irradiation could be recommended for apple and pear. Current fumigation was perfect in its disinfesting capability, but it caused the detrimental effects on physical quality of agricultural produce. Whereas, irradiation doses suitable for controlling the pests did not induce any significant changes in the quality of the samples. 40 refs., 64 figs., 160 tabs. (Author)

    Full Text Available The article is based on several interrogative assumptions related to the positive impact of the crises and the recession on determinations in the econometric models of Romania’s GDP as a variable dependent in relation to the export and import of fuels. After a short introductory section, which details, in a relative manner, the overall goal and the objectives of the paper, a first section makes use of elasticity and the modern solutions of building the coefficient of elasticity, proposing an original alternative to existing variants, and afterwards the next section builds on these statistical tools in the econometric modeling of Romania’s GDP, starting from the ratios and value indicators and offering a few original models where the export and import of fuels are the key initial explanatory factors. The final remarks reinterpret the role of the energy resources, as well as that of the related flows, in enhancing statistical connections, and especially the role of crises and recessions in validating econometric models, by raising their degree of predictability.

  15. Trichodiene Production in a Trichoderma harzianum erg1-Silenced Strain Provides Evidence of the Importance of the Sterol Biosynthetic Pathway in Inducing Plant Defense-Related Gene Expression.

    Trichoderma species are often used as biocontrol agents against plant-pathogenic fungi. A complex molecular interaction occurs among the biocontrol agent, the antagonistic fungus, and the plant. Terpenes and sterols produced by the biocontrol fungus have been found to affect gene expression in both the antagonistic fungus and the plant. The terpene trichodiene (TD) elicits the expression of genes related to tomato defense and to Botrytis virulence. We show here that TD itself is able to induce the expression of Botrytis genes involved in the synthesis of botrydial (BOT) and also induces terpene gene expression in Trichoderma spp. The terpene ergosterol, in addition to its role as a structural component of the fungal cell membranes, acts as an elicitor of defense response in plants. In the present work, using a transformant of T. harzianum, which is silenced in the erg1 gene and accumulates high levels of squalene, we show that this ergosterol precursor also acts as an important elicitor molecule of tomato defense-related genes and induces Botrytis genes involved in BOT biosynthesis, in both cases, in a concentration-dependent manner. Our data emphasize the importance of a balance of squalene and ergosterol in fungal interactions as well as in the biocontrol activity of Trichoderma spp. PMID:26168138

    Full Text Available Wild pepper (Piper peepuloides Roxb., family: Piperaceae is an evergreen climber which grows wild in tropical evergreen forests and subtropical evergreen forests of northeast India. This plant grows luxuriantly in the areas with high rainfall at lower elevations ranging from 100 to 800 m above mean sea level. In Meghalaya, to meet the market demand, farmers have domesticated it in arecanut agroforests and betel leaf agroforests. We found that the mean density of wild pepper in arecanut agroforest is 585 stem/ha and only 85 stem/ha in natural forest. In India, wild pepper is used in a variety of Ayurvedic medicines. Local people of Meghalaya uses powdered dry seeds mixed with honey and egg yolk for the treatment of severe cough. The study reveals that the average gross annual production of wild pepper is 7 quintals/ha, and final market price fetches Rs. 336,000/ha, out of which 42% of the money goes to the grower, 16% to local trader, 23% to dealer, 17% to retailer, 1.2% to wages of labourers, and 0.6% to transport.

  17. Reassessing the importance of the colour-singlet contributions to direct J/psi+W production at the LHC and the Tevatron

    CERN Document Server

    Lansberg, J P

    2013-01-01

    Contrary to earlier claims, we show that there are two kinds of colour-singlet contributions to the hadroproduction of J/psi in association with a W boson at orders alpha^3_S alpha and alpha^3 and that they are sizable, if not dominant over the colour-octet contributions. They come from the partonic processes s+g-> J/psi + c +W and q+q'-bar -> gamma* W -> J/psi W, which have systematically been overlooked in the literature until now. Our conclusion is that the hadroproduction of a J/psi in association with a W boson cannot be claimed as a clean probe of the colour-octet mechanism --and in turn of the NRQCD universality-- because of the sizable colour-singlet contribution and because of the small rate for this process at the LHC. During this analysis, we have also noted that, for reactions such as the production of a J/psi by light quark-antiquark fusion, the colour-singlet contribution via an off-shell photon is of the order of the expectation from the colour-octet contribution via an off-shell gluon. This is...

  18. Study of important parameters on the irradiation of 124Xe, to improve the production of 123I with high purity using the Cyclone-30 cyclotron at IPEN-CNEN/SP

    International Nuclear Information System (INIS)

    The development of diagnosis equipment and therapy procedures in nuclear medicine depends on the availability of commercial radioisotopes. IPEN is the most important institution that provides radioisotopes for national market. In order to achieve this function, IPEN had invested in the acquisition of a 30 MeV Cyclone-30 cyclotron to produce mainly 18F, 67Ga, 201Tl and 123I. The 123I production is the aim of the present work. With the 123I routine production data obtained by proton irradiation of Xe targets with an enrichment greater than 99.8%, it was possible to identify the important parameters that have direct influence on the production yield of high purity degree 123I. Even though the methodology for the commercial production of 123I, there are an scarcity of operational parameters data for this task. In this work the evaluated parameters were: 124Xe pressure, proton beam quality, irradiation time, operational temperature of the irradiation system under irradiation, waiting time to obtain 123I, temperature of washing solution and the impact of the internal Ni coating in the target. With the obtained results it was possible to modify the operational conditions for routine production and increasing the efficiency in about 30%. (author)

    Full Text Available Abstract Background The Gram-negative bacterium Xanthomonas citri subsp. citri (Xac causes citrus canker, one of the most destructive diseases of citrus worldwide. In our previous work, a transposon mutant of Xac strain 306 with an insertion in the XAC3110 locus was isolated in a screening that aimed at identifying genes related to biofilm formation. The XAC3110 locus was named as bdp24 for biofilm-defective phenotype and the mutant was observed to be affected in extracellular polysaccharide (EPS and lipopolysaccharide (LPS biosynthesis and cell motility. In this study, we further characterized the bdp24 (XAC3110 gene (designated as gpsX using genetic complementation assays and expanded the knowledge about the function of the gpsX gene in Xac pathogenesis by investigating the roles of gpsX in EPS and LPS production, cell motility, biofilm formation on host leaves, stress tolerance, growth in planta, and host virulence of the citrus canker bacterium. Results The gpsX gene encodes a putative glycosyltransferase, which is highly conserved in the sequenced strains of Xanthomonas. Mutation of gpsX resulted in a significant reduction of the amount of EPS and loss of two LPS bands visualized on sodium dodecylsulphate- polyacrylamide gels. Biofilm assays revealed that the gpsX mutation affected biofilm formation by Xac on abiotic and biotic surfaces. The gpsX mutant showed delayed bacterial growth and caused reduced development of disease symptoms in susceptible citrus leaves. The gpsX mutant was more sensitive than the wild-type strain to various stresses, including the H2O2 oxidative stress. The mutant also showed attenuated ability in cell motility but not in flagellar formation. Quantitative reverse transcription-PCR assays indicated that mutation of gpsX did not affect the expression of virulence genes such as pthA in Xac strain 306. The affected phenotypes of the gpsX mutant could be complemented to wild-type levels by the intact gpsX gene

  3. Beyond buffer zone protection: a comparative study of park and buffer zone products' importance to villagers living inside Royal Chitwan National Park and to villagers living in its buffer zone.

    Even after 30 years of strict de jure protection, today's de facto extraction of products from Nepal's Royal Chitwan National Park (RCNP) and their great economic importance to local households suggests that this reality should be explicitly internalised in managing this world heritage park. Several studies have quantified local people's use of protected areas and estimated the value of such areas to them. However, few studies incorporate economic analyses to investigate the effect of management interventions on local communities' resource use and collection behaviour. In Nepal, buffer zones and especially buffer zone community forestry are seen as means to define and demarcate places, where local people may legally extract goods that are either identical to or relevant substitutes for products that are collected in protected areas. The intention is to resolve park-people conflicts over resource use. This article presents the findings of an in-depth study of the importance of natural resources to the livelihoods of 18 households. One village was located inside RCNP with no realistic alternatives to Park resources, while the other is located in the buffer zone with equal distance to the Park, a national forest and their community forest. For each household, the collection of products, allocation of time, and purchase and sale of goods were recorded daily through 12 consecutive months and economic values were calculated on the basis of local market prices and recorded quantities. The study shows that products from RCNP are of great importance to the livelihoods of local people. Furthermore, we find that products collected in the national forest substitute products from the Park, while the substitution effect of the community forest is small. Accordingly, the study illustrates that, irrespective of buffer zone community forestry, there is still a gap between local people's need for supplementing natural resources and their rights to satisfy them on a legal basis

  6. Mexico: Imports or exports?

    International Nuclear Information System (INIS)

    This presentation provides an overview of Mexico's energy sector. Proven oil reserves place Mexico in ninth position in the world and fourth largest in natural gas reserves. Energy is one of the most important economic activities of the country, representing 3 per cent of Gross Domestic Product (GDP). Oil exports represent 8.4 per cent of total exports. Approximately 40 per cent of total public investment is earmarked for energy projects. The author discusses energy resources and energy sector limitations. The energy sector plan for the period 2001-2006 is discussed. Its goals are to ensure energy supply, to develop the energy sector, to stimulate participation of Mexican enterprises, to promote renewable energy sources, and to strengthen international energy cooperation. The regulatory framework is being adapted to increase private investment. Some graphs are presented, displaying the primary energy production and primary energy consumption. Energy sector reforms are reviewed, as are electricity and natural gas reforms. The energy sector demand for 2000-2010 and investment requirements are reviewed, as well as fuel consumption for power generation. The author discusses the National Pipeline System (SNG) and the bottlenecks caused by pressure efficiency in the northeast, flow restriction on several pipeline segments, variability of the Petroleos Mexicanos (PEMEX) own use, and pressure drop on central regions. The entire prospect for natural gas in the country is reviewed, along with the Strategic Gas Program (PEG) consisting of 20 projects, including 4 non-associated natural gas, 9 exploration and 7 optimization. A section dealing with multiple service contracts is included in the presentation. The authors conclude by stating that the priority is a national energy policy to address Mexico's energy security requirements, to increase natural gas production while promoting the diversification of imports, and a regulatory framework to be updated in light of current

    Full Text Available TOM1L (target of Myb-1 Like was identified as a binding partner for the full length and catalytically-active Lck in a yeast 2-hybrid screening assay. Here we show that in Jurkat T cells stimulated by CD3/CD28 coligation where the expression of TOM1L is reduced by lenti virus mediated-siRNA results in a dramatically lower IL-2 production. The production of IL-2 in siRNA treated cells stimulated with PMA/ionomycin was not affected indicating an involvement of TOM1L in a pathway proximal of TCR and CD28. The coexpression of Fyn with TOM1L increased the level of the phosphorylated form of Fyn indicating that TOM1L has the ability to activate Fyn. The ability of TOM1L to activate Fyn was further shown in a kinase assay using angiotensin II as a substrate. By confocal microscopy, we show that the expression of TOM1L in non-treated HeLa and SK-N-SH cells colocalizes with the mitochondrial membrane but not with lysosomal compartments or the trans-Golgi network. Furthermore, we show that the over-expression of TOM1L in Jurkat cells causes an increase of the STAT3 expression . Based on our results, we here propose that TOM1L is involved in a novel signaling pathway that is important for the IL-2 production in T cells.

  10. Normalization of NDVI from Different Sensor System using MODIS Products as Reference

    International Nuclear Information System (INIS)

    Medium Resolution NDVI(Normalized Difference Vegetation Index) from different sensor systems such as Landsat, SPOT, ASTER, CBERS and HJ-1A/1B satellites provide detailed spatial information for studies of ecosystems, vegetation biophysics, and land cover. Limitation of sensor designs, cloud contamination, and sensor failure highlighted the need to normalize and integrate NDVI from multiple sensor system in order to create a consistent, long-term NDVI data set. In this paper, we used a reference-based method for NDVI normalization. And present an application of this approach which covert Landsat ETM+ NDVI calculated by digital number (NDVIDN) to NDVI calculated by surface reflectance (NDVISR) using MODIS products as reference, and different cluster was treated differently. Result shows that this approach can produce NDVI with highly agreement to NDVI calculated by surface reflectance from physical approaches based on 6S (Second Simulation of the satellite Signal in the Solar Spectrum). Although some variability exists, the cluster specified reference based approach shows considerable potential for NDVI normalization. Therefore, NDVI products in MODIS era from different sources can be combined for time-series analysis, biophysical parameter retrievals, and other downstream analysis

We use a rich product-firm-level dataset providing both revenue and quantities of all products for a large panel of Danish manufacturing firms over the period 1998-2005 and link it to another...... dataset describing firms' international trade transactions by product. We use our detailed product level information to compute a firm level deflator and avoid the criticism of biased estimates due to the use of industry level deflator. We find that both importing and exporting behaviours are strongly...... associated with productivity, but firms involved in both importing and exporting are the most productive. We also find evidence of a self-selection into importing and exporting but no learning effect. Finally, we try to distinguish between cost effect and product quality effect by analyzing the importance of...

    An important ceramics material dated back to the 12th-14th centuries has been excavated in Pergamon (Turkey). Among these findings, wasters, tripod stilts and unfinished ware attest to local production in the Byzantine period. Elemental analysis by the methods PIXE (Particle Induced X-ray Emission) and INAA (Instrumental Neutron Activation Analysis) has been performed on a representative sampling of 160 sherds, including attested local material. Multivariate statistical techniques were used to classify the sherds into groups of similar composition and thus to distinguish ceramics made in Pergamon from imported wares. Several groups of local production have been constituted, which correspond to wares differing in date and fabric. The geochemical characterization of the pastes, complemented with petrographical and mineralogical data, shows that specific raw materials have been used to manufacture each ware. The analytical data related to ceramics made in Pergamon will serve as reference data for future provenance studies. Such reference groups of Byzantine ceramics are very rare, and therefore the ceramics imported into Pergamon cannot be attributed as to their origin. Among the ceramics widely diffused in the Byzantine world, some importations belonging to the ``fine sgraffito`` and ``Zeuxippus ware`` types have been identified. The latter type has been a source of stylistic influence for the workshops of Pergamon, since the analyses show that imitated ``Zeuxippus ware`` has been produced there. These imitations were probably themselves diffused on a regional scale. (author). 238 refs., 48 figs., 53 tabs., 22 photos., 8 appends.

    Full Text Available The poultry industry is characterized for its constant search for productivity and profitability, which are based on flock health status. Brazilian Commercial laying hens (Gallus gallus domesticus have been impacted significantly by mite infestations. This review aims to compile the literature on the occurrence, economic losses, biology, epidemiology and control of mite species considered important for the Brazilian laying poultry industry. The national experience was compared with practices of other countries and a scarcity of studies on this subject in Brazil was evident. The poultry industry has prioritized the use of pesticides to control infestations with little regard for the adverse effects. In this context, the integrated control programs using several strategies simultaneously constitute the best alternative to mite control. Integrated control programs involve measures of chemical, physical and biological nature, as well as attention to cultural aspects. However, studies should be performed aiming at the development of new control methods, evaluating the adequacy of practices developed in other countries to the national reality.A indústria avícola é caracterizada por sua constante busca por produtividade e lucratividade, que se relacionam diretamente ao status sanitário dos plantéis avícolas.

    Understanding the organic chemistry of molecular clouds, particularly the formation of biologically important molecules, is fundamental to the study of the processes which lead to the origin, evolution and distribution of life in the Galaxy. Determining the level of molecular complexity attainable in the clouds, and the nature of the complex organic material available to protostellar disks and the planetary systems that form from them, requires an understanding of the possible chemical pathways and is therefore a central question in astrochemistry. We have thus searched for prebiologically important molecules in the hot molecular cloud cores: Sgr B2(N-LMH), W51 e1/e2 and Orion-KL. Among the molecules searched: Pyrimidine is the unsubstituted ring analogue for three of the DNA and RNA bases. 2H-Azirine and Aziridine are azaheterocyclic compounds. And Glycine is the simplest amino acid. Detections of these interstellar organic molecular species will thus have important implications for Astrobiology. Our preliminary results indicate a tentative detection of interstellar glycine. If confirmed, this will be the first detection of an amino acid in interstellar space and will greatly strengthen the thesis that interstellar organic molecules could have played a pivotal role in the prebiotic chemistry of the early Earth.

The main purpose of building codes are to protect public health, safety and general welfare as they relate to the construction and occupancy of buildings and structures. The building code becomes law of a particular jurisdiction when formally enacted by the appropriate governmental or private authority. Building codes are generally intended to be applied by architects, engineers, constructors and regulators but are also used for various purposes by safety inspectors, environmental scientists, real estate developers, subcontractors, manufacturers of building products and materials, insurance companies, facility managers, tenants and others.

    Full Text Available Monitoring the performance of lubricants in practical application has multiple significance for both the consumer and the lubricant manufacturer. The primary significance for the consumer is extended life and timely change of lubricants, which keeps the costs of maintenance down. The lubricant manufacturer gains by creating a partner relationship with the consumer, as well as creating the possibility of gathering information about the performance of his product which will serve as the foundation for its further improvement and development. If we wish to maintain technical systems so that they have minimum halts and costs caused by halt removal or system failures, we must monitor data indicating equipment condition throughout the system operation. It is especially difficult to obtain data on equipment condition for parts which cannot be observed due to their position. In such cases, the oil analysis enables a continuous equipment condition monitoring and timely response in order to prevent undesirable prolonged halts.

But in these difficult days of financial austerity, even the most obvious benefits of science have to undergo careful scrutiny. Eradicating poverty and hunger is a worldwide priority, and activities that do not directly attempt to resolve these issues can be hard to justify and support. However, several studies have told us that investing in science education, research and technology provides a great return (not only economically, but culturally and indirectly for the population in general and has helped countries to face and overcome crises.

    With increased utilization of platelet-rich plasma (PRP), it is important for clinicians to understand the United States, the Food and Drug Administration (FDA) regulatory role and stance on PRP. Blood products such as PRP fall under the prevue of FDA's Center for Biologics Evaluation and Research (CBER). CBER is responsible for regulating human cells, tissues, and cellular and tissue-based products. The regulatory process for these products is described in the FDA's 21 CFR 1271 of the Code of Regulations. Under these regulations, certain products including blood products such as PRP are exempt and therefore do not follow the FDA's traditional regulatory pathway that includes animal studies and clinical trials. The 510(k) application is the pathway used to bring PRP preparation systems to the market. The 510(k) application allows devices that are "substantially equivalent" to a currently marketed device to come to the market. There are numerous PRP preparation systems on the market today with FDA clearance; however, nearly all of these systems have 510(k) clearance for producing platelet-rich preparations intended to be used to mix with bone graft materials to enhance bone graft handling properties in orthopedic practices. The use of PRP outside this setting, for example, an office injection, would be considered "off label." Clinicians are free to use a product off-label as long as certain responsibilities are met. Per CBER, when the intent is the practice of medicine, clinicians "have the responsibility to be well informed about the product, to base its use on firm scientific rationale and on sound medical evidence, and to maintain records of the product's use and effects." Finally, despite PRP being exempted, the language in 21 CFR 1271 has caused some recent concern over activated PRP; however to date, the FDA has not attempted to regulate activated PRP. Clinicians using activated PRP should be mindful of these concerns and continued to stay informed. PMID

    The Pimenta Bueno sedimentary basin was studied with remote sensing techniques and images. A structural analysis was performed by statistical treatment over linear element of relief and drainage obtained from LANDSAT/TM images and radar mosaic in the scale of 1:250,000. Interpretation of the anisotropy drainage curves and interpretation of the magnetic lineaments in the whole area was also done. The main structural trends of fractures found in this area are: N85E-S80E, N10E-N10W, and N40-50E. The fractures in the range N85E-S80E were responsible for the control of paleozoic sedimentation in this basin. The drainage anisotropy analysis over the cretaceous sedimentation gave strong coherence with the most important regional lineaments, making the identification of highs and lows of the basement easy.

    Galindo-Hernández, Félix; Domínguez, J. M.; Portales, Benjamín

    2015-08-01

    Newer catalysts for the methane reforming with H2S are designed, which are based on Fe2O3/γ-Al2O3, nanocrystalline γ-Al2O3 supports, and 1.0 to 6.0 wt% Fe. The main phases are identified as hematite and γ-Al2O3, with sizes of about 2-4 nm. The structural features are characterized by X-ray diffraction, Rietveld's Refinement and Radial Distribution Function analysis. The textural properties of these catalysts are determined by N2 sorption and surface fractal dimension calculations. Also, the electronic states are inferred by Mössbauer and UV-Vis (diffuse reflectance) spectroscopies. The activity of Fe2O3/γ-Al2O3 catalysts in the methane reforming is tested in a fixed bed type reactor. Further calculations indicate that Fe2O3/γ-Al2O3 catalysts go through a charge transfer decrease, which depends on the iron content, i.e., from 1.08 to 0.88 eV; Mössbauer spectroscopy reveals that Fe3+ ions adopt a tetrahedral coordination, which coincides with their higher activity for hydrogen production, with respect to catalysts having octahedral coordination. The specific surface area of these catalysts is about 84 m2 g-1, with a mean pore diameter of 2.5 nm. A mechanism for the methane reforming with H2S is proposed herein.

    International Nuclear Information System (INIS)

    This study first gives an overview of existing tools and methodological challenges to account emissions included in consumed products fabricated elsewhere. It notably discusses the passage from a methodology based on a production principle to a methodology based on a consumption principle, outlines the different methodologies associated with the different analysis levels, and the importance of uncertainty sources. The second part proposes a view on emission flows included in exports and imports. It addresses the following issues: the international level, increasing importance of emissions transferred via world trade, emissions related to consumption per capita and per social class, carbon and energy intensity of products at the origin of emissions, composition of imported and exported products and intensity of their emissions, impact of a methodological change on greenhouse gas emissions by France, extent of emissions imported in France, and Germany as the first trade partner and emission importer of France. The third part discusses the political implications of an accounting of emissions related to consumption and to world trade

In order to achieve this function, IPEN had invested in the acquisition of a 30 MeV Cyclone-30 cyclotron to produce mainly {sup 18}F, {sup 67}Ga, {sup 201}Tl and {sup 123}I. The {sup 123}I production is the aim of the present work. With the {sup 123}I routine production data obtained by proton irradiation of Xe targets with an enrichment greater than 99.8%, it was possible to identify the important parameters that have direct influence on the production yield of high purity degree {sup 123}I. Even though the methodology for the commercial production of {sup 123}I, there are an scarcity of operational parameters data for this task. In this work the evaluated parameters were: {sup 124}Xe pressure, proton beam quality, irradiation time, operational temperature of the irradiation system under irradiation, waiting time to obtain {sup 123}I, temperature of washing solution and the impact of the internal Ni coating in the target. With the obtained results it was possible to modify the operational conditions for routine production and increasing the efficiency in about 30%. (author)

    The Gram-negative bacterium Pasteurella multocida is the causative agent of a number of economically important animal diseases, including avian fowl cholera. Numerous P. multocida virulence factors have been identified, including capsule, lipopolysaccharide (LPS), and filamentous hemagglutinin, but little is known about how the expression of these virulence factors is regulated. Hfq is an RNA-binding protein that facilitates riboregulation via interaction with small noncoding RNA (sRNA) molecules and their mRNA targets. Here, we show that a P. multocida hfq mutant produces significantly less hyaluronic acid capsule during all growth phases and displays reduced in vivo fitness. Transcriptional and proteomic analyses of the hfq mutant during mid-exponential-phase growth revealed altered transcript levels for 128 genes and altered protein levels for 78 proteins. Further proteomic analyses of the hfq mutant during the early exponential growth phase identified 106 proteins that were produced at altered levels. Both the transcript and protein levels for genes/proteins involved in capsule biosynthesis were reduced in the hfq mutant, as were the levels of the filamentous hemagglutinin protein PfhB2 and its secretion partner LspB2. In contrast, there were increased expression levels of three LPS biosynthesis genes, encoding proteins involved in phosphocholine and phosphoethanolamine addition to LPS, suggesting that these genes are negatively regulated by Hfq-dependent mechanisms. Taken together, these data provide the first evidence that Hfq plays a crucial role in regulating the global expression of P. multocida genes, including the regulation of key P. multocida virulence factors, capsule, LPS, and filamentous hemagglutinin.

    Full Text Available Packaging has been considered the main vehicle for sales, brand building and product identity, since it is the first contact with the product that the consumer has, it is fundamental when choosing and buying a product. In this sense, the packaging is a silent salesperson, because it is up to the package to attract attention, create interest and desire, show the quality of the product and close the sale within seconds. Packaging has contributed to corporate communication with consumers; it provides product protection, storage and convenience, as products move through the value chain. Thinking about it, the product cannot be planned separately from its packaging, and it should not be defined based only on engineering, marketing, communications or economics. The packaging concept has expanded and gained product status; packaging is able to communicate the same language of convenience wherever it goes. Today, packaging industries are taking advantage of this opportunity to differentiate their products through packaging, finding that it is not enough for the package to be beautiful, unbreakable, or preserve the flavor and freshness of foods. Within this context, the objective of this research is to analyze, from the point of view of consumers, the most important product packaging attributes at the time of purchase. For this purpose, the data obtained in this study was run through the Statistica 8.0 and SPSS 16 (Statistical Package Social Sciences software’s.

    @@ Net imports of crude oil, product oil, liquefied petroleum gas (LPG), and other oil products rose by 16.2% and hit a historic high of 253.7 million tons in 2010.Among these, net imports of crude oil reached 236.3 million tons, 93% of the total, and the growth rate was as high as 19.0% (see Fig.1).As the demand for oil products maintained a robust growth and the scale of oil refineries was expanded further, China's processing quantity of crude oil rose by 50 million tons in 2010, 13.4% higher than the figure in 2009.Sales of oil products were brisk, in particular diesel demand was increased suddenly in the fourth quarter of 2009.Therefore, China's apparent need (production + net imports) of seven kinds of main oil products including gasoline, kerosene, diesel, lubricant oil, fuel oil, LPG and chemical light oil was increased by 11.6% in 2010 (Table 1 and Table 2).

  6. Zirconium - an imported mineral commodity

    International Nuclear Information System (INIS)

    This report examines Canada's position in regard to the principal zirconium materials: zircon; fusion-cast zirconium-bearing refractory products; zirconium-bearing chemicals; and zirconium metal, master alloys, and alloys. None of these is produced in Canada except fused alumina-zirconia and certain magnesium-zirconium alloys and zirconium-bearing steels. Most of the 3 000-4 000 tonnes of the various forms of zircon believed to be consumed in Canada each year is for foundry applications. Other minerals, notably chromite, olivine and silica sand are also used for these purposes and, if necessary, could be substituted for zircon. Zirconium's key role in Canada is in CANDU nuclear power reactors, where zirconium alloys are essential in the cladding for fuel bundles and in capital equipment such as pressure tubes, calandria tubes and reactivity control mechanisms. If zirconium alloys were to become unavailable, the Canadian nuclear power industry would collapse. As a contingency measure, Ontario Hydro maintains at least nine months' stocks of nuclear fuel bundles. Canada's vulnerability to short-term disruptions to supplies of nuclear fuel is diminished further by the availability of more expensive electricity from non-nuclear sources and, given time, from mothballed thermal plants. Zirconium minerals are present in many countries, notably Australia, the Republic of South Africa and the United States. Australia is Canada's principal source of zircon imports; South Africa is its sole source of baddeleyite. At this time, there are no shortages of either material. Canada has untapped zirconium resources in the Athabasca Oil Sands (zircon) and at Strange Lake along the ill-defined border between Quebec and Newfoundland (gittinsite). Adequate metal and alloy production facilities exist in France, Japan and the United States. No action by the federal government in regard to zirconium supplies is called for at this time

    Full Text Available Active pharmaceutical ingredients represent a group of emerging environmental contamination. Even in trace amounts, they are of great concern due to then continuous introduction into the environment, their impact an ecosystem and human and vetenery health is of great importance. This has given birth to the science of Ecopharmacovigilance (EPV. It aims to ensure that significant environmental issues associated with pharmaceuticals in the environment are identified and managed appropriately. EPV has become a research hotspot in Europe and North America. Environmental Risk assessment (ERA is now a regulatory requirement prior to launch of any new drug. The biggest difference and greatest challenge concerns signal detection in the environment and the dilemma of identifying cause and effect. In the background of growing Indian pharmaceutical industry and drug consumption, India should shoulder responsibility for its own environment and people along with the world ecosystem. Compared to the west EPV in India is in infancy ERA is now a regulatory requirement prior to launch of any new drug. However there is no formal frame-work to monitor for potential adverse effects in the environment, once a product has been launched. There should be laws and regulations on EPV, rational medication, drug take back programs, strengthening policy guided and scientific researches on EPV by pharmaceutical firms and academia.

    Sufficiently fast chemical equilibration of (strange) antibaryons in an environment of nucleons, pions and kaons during the course of a relativistic heavy ion collision can be understood by a `clustering' of mesons to built up baryon-antibaryon pairs. This multimesonic (fusion-type) process has to exist in medium due to the principle of detailed balance. Novel numerical calculations for a dynamical setup are presented. They show that at maximum SPS energies - yields of each antihyperon specie are obtained which are consistent with chemical saturated populations of T approximately=150-160 MeV, in line with popular chemical freeze-out parameters extracted from thermal model analyses.

Here, we review the literature on the impact of importance on prospective memory performance. We highlight different methods used to manipulate the importance of a prospective memory task such as providing rewards, importance relative to other ongoing activities, absolute importance, and providing social motives. Moreover, we address the relationship between importance and other factors known to affect prospective memory and ongoing task performance such as type of prospective memory task (time-, event- or activity-based, cognitive loads, and cue focality. Finally, we provide a connection to motivation, we summarize the effects of task importance and we identify important venues for future research.

  1. The Importance of Water-Hydrocarbon Phase Equilibria During Reservoir Production and Drilling Operations Nouveaux défis liés à la présence d'équilibres eau-hydrocarbures lors des opérations de production et de forage

    Directory of Open Access Journals (Sweden)

    Zhou H.

    2006-12-01

    Full Text Available The inevitable presence of water in high pressure-high temperature reservoirs leads to a number of new challenges for petroleum engineers. A brief state of the art on water-hydrocarbon phase equilibria is presented. It appears that large amounts of water may be present in the hydrocarbon phase (up to 10% molar, and non negligible amounts of gas can dissolve in water. Based on experimental data, a large number of models have been developed. However, concerning the limitations of the data, caution is expressed about the correctness of some models. Recent studies have proven the usefulness of Henry's constants to predict hydrocarbon solubilities in water. The new challenges that are raised by this problem are discussed based on a number of recent publications. The water present in the hydrocarbon may lead to salt deposits downwell, and it must be taken into account in order to estimate the amount of gas in place. It can also result in modifications of the saturation pressure. Due to the presence of water, additional treatment is needed for pipe transport. On the other hand, the large amount of hydrocarbons dissolved in the water phase may result in a modification of the hydrocarbon composition, especially when reservoir pressure becomes very low. The increased toxicity of the water, containing either H2S or aromatics, can become a real burden for gas reservoirs in contact with aquifers or when disposing of production water. During drilling, large amounts of dissolved gas can become very hazardous, increasing the risk of eruption. A particular attention must be paid to acid gas injection in reservoirs, as the true effect of the injected gas may not be straightforward to predict. In conclusion, in light of the industrial importance of this information, some general guidelines are provided concerning additional data to be gathered and ideas for improving current models.

    2013-03-01

    A variety of centrality measures can be defined on a network to determine the global `importance' of a node i. However, the inhomogeneity of complex networks implies that not all nodes j will consider i equally important. In this talk, we use a linearized form of the Generalized Erdos numbers [Morrison and Mahadevan EPL 93 40002 (2011)] to define a pairwise measure of the importance of a node i from the perspective of node j which incorporates the global network topology. This localized importance can be used to define a global measure of centrality that is consistent with other well-known centrality measures. We illustrate the use of the localized importance in both artificial and real-world networks with a complex global topology.

    CERN Document Server

    Frikha, Noufel

    2011-01-01

    We investigate in this paper an alternative method to simulation based recursive importance sampling procedure to estimate the optimal change of measure for Monte Carlo simulations. We propose an algorithm which combines (vector and functional) optimal quantization with Newton-Raphson zero search procedure. Our approach can be seen as a robust and automatic deterministic counterpart of recursive importance sampling by means of stochastic approximation algorithm which, in practice, may require tuning and a good knowledge of the payoff function in practice. Moreover, unlike recursive importance sampling procedures, the proposed methodology does not rely on simulations so it is quite generic and can come along on the top of Monte Carlo simulations. We first emphasize on the consistency of quantization for designing an importance sampling algorithm for both multi-dimensional distributions and diffusion processes. We show that the induced error on the optimal change of measure is controlled by the mean quantizatio...

During quiescence and cell cycle arrest, proteasomes accumulate in granules in close proximity to the nuclear envelope/ER. With prolonged quiescence in yeast, these proteasome granules pinch off as membraneless organelles, and migrate as stable entities through the cytoplasm. Upon exit from quiescence, the proteasome granules clear and the proteasomes are rapidly transported into the nucleus, a process reflecting the dynamic nature of these multisubunit complexes. Due to the scarcity of studies on the nuclear transport of mammalian proteasomes, we summarised the current knowledge on the nuclear import of yeast proteasomes. This pathway uses canonical nuclear localisation signals within proteasomal subunits and Srp1/Kap95, and the canonical import receptor, named importin/karyopherin αβ. Blm10, a conserved 240 kDa protein, which is structurally related to Kap95, provides an alternative import pathway. Two models exist upon which either inactive precursor complexes or active holo-enzymes serve as the import cargo. Here, we reconcile both models and suggest that the import of inactive precursor complexes predominates in dividing cells, while the import of mature enzymes mainly occurs upon exit from quiescence.

    A physical-chemical model which is an extension of that of Hong and Carmichael (1983) is used to investigate the role of formaldehyde in cloud chemistry. This model takes into account the mass transfer of SO2, O3, NH3, HNO3, H2O2, CO2, HCl, HCHO, O2, OH and HO2 into cloud droplets and their subsequent chemical reactions. The model is used to assess the importance of S(IV)-HCHO adduct formation, the reduction of H2O2 by HCHO, HCHO-free radical interactions, and the formation of HCOOH in the presence of HCHO in cloud droplets. Illustrative calculations indicate that the presence of HCHO inhibits sulfate production rate in cloud droplets. The direct inhibition of sulfate production rate in cloudwater due to nucleophilic addition of HSO3(-) to HCHO(aq) to form hydroxymethanesulfonate is generally low for concentrations of HCHO typical of ambient air. However, inhibition of sulfate production due to formaldehyde-free radical interactions in solution can be important. These formaldehyde-free radical reactions can also generate appreciable quantities of formic acid.

  6. Dynamically consistent oil import tariffs

    International Nuclear Information System (INIS)

    The standard theory of optimal tariffs considers tariffs on perishable goods produced abroad under static conditions, in which tariffs affect prices only in that period. Oil and other exhaustable resources do not fit this model, for current tariffs affect the amount of oil imported, which will affect the remaining stock and hence its future price. The problem of choosing a dynamically consistent oil import tariff when suppliers are competitive but importers have market power is considered. The open-loop Nash tariff is solved for the standard competitive case in which the oil price is arbitraged, and it was found that the resulting tariff rises at the rate of interest. This tariff was found to have an equilibrium that in general is dynamically inconsistent. Nevertheless, it is shown that necessary and sufficient conditions exist under which the tariff satisfies the weaker condition of time consistency. A dynamically consistent tariff is obtained by assuming that all agents condition their current decisions on the remaining stock of the resource, in contrast to open-loop strategies. For the natural case in which all agents choose their actions simultaneously in each period, the dynamically consistent tariff was characterized, and found to differ markedly from the time-inconsistent open-loop tariff. It was shown that if importers do not have overwhelming market power, then the time path of the world price is insensitive to the ability to commit, as is the level of wealth achieved by the importer. 26 refs., 4 figs

  7. Uses of risk importance measures

    International Nuclear Information System (INIS)

    Risk importance measures provide an understandable and practical way of presenting probabilistic safety analysis results which too often tend to remain abstract numbers without real insight into the content. The report clarifies the definitions, relationships and interpretations of the three most basic measures: Risk increase factor, risk decrease factor, and fractional contribution. The above three measures already cover the main types of risk importance measures. Many other importance measures presented in literature are close variants to some of these three measures. They are related in many cases so that, for a technical system considered, the two other measures can be derived from the one calculated first. However, the practical interpretations are different, and hence each three measures have their own uses and rights to existence. The fundamental aspect of importance measures is, that they express some specific influence of a basic event on the total risk. The basic failure or error events are the elements from which the reliability and risk models are constituted. The importance measures are relative, which is an advantage compared to absolute risk numbers, due to insensitivity with respect to quantification uncertainties. Therefore they are particularly adapted to give first hand guidance where to focus main interest from the system's risk and reliability point of view and wherefrom to continue the analysis with more sophisticated methods requiring more effort

  8. The important role of energy taxation

    International Nuclear Information System (INIS)

    This is a discussion of the importance of energy taxation in EU countries. Although natural gas is the most environmentally friendly of the fossil fuels, its use may be taxed far harder in the future. The price effects of such a development are discussed. The increasing taxes on oil products which has taken place in the OECD area may come to slow down if competing economies elsewhere do not follow the same policy. The challenge is particularly coming from the new economies in Asia, included the giants China and India, which now have far larger economic growth than the OECD area with a corresponding increased energy consumption. Strong competition may develop both in the markets for products and in the market for factor inputs (energy), so that taxes within the OECD area no longer can be increased but must be lowered. This may also happen if the oil price is high over some time. As far as taxes on natural gas in the European gas market is concerned, the large industrial users will face a regional competitive situation for natural gas as an input factor, while they are globally in a competitive situation for oil as an input factor. In product markets, this industry competes globally in the same way, as does industry that uses oil. This may lead to European countries wishing to tax the use of natural gas in the consumer sector harder than gas for industry and the production of electricity

    Sustained economic growth in China has triggered a surge of energy imports, especially oil imports. This paper investigates the determinants of China’s energy import demand by using cointegraiton and VECM techniques. The findings suggest that, in the long run, growth of industrial production and expansion of transport sectors affect China’s oil imports, while domestic energy output has a substitution effect. Thus, as the Chinese economy industrializes and the automotive sector expands, China’...

    Full Text Available Secure raw material supply is one of the most important topics for industry. Growing economies such as China, India, Brazil and others increase the global demand and in the same time the competition for resources. In order to undertake appropriate actions the most important raw materials should be identified. The aim of this study was to identify the most important raw materials for Lithuanian economy in terms of economic importance, supply and environmental risks. The methodology used in the study relies on three sustainability dimensions accordingly expressed by three indicators: Economic Importance (Economic dimension; Supply Risk (Social dimension; Environmental Country Risk (Environmental dimension. The methodology used to define these indicators on imported resources for Lithuanian industry was adapted from report on critical raw materials for European Union (Report of the Ad-hoc Working Group on defining critical raw materials 2010 published by European Commission in June 2010. Critical raw materials are considered to be economically important and the subject to a higher risk of supply interruption. All materials investigated in this study were combined into five groups: chemicals, metals, building materials, paper, paperboard and wood, other materials. Only the imported raw materials were selected for further analysis. The significance of raw material import was considered as important according to the ratio of production and consumption of certain material. After the analysis of statistical information about raw materials import in Lithuania and the actual countries of origin of these resources twenty one raw material was selected for further investigation. According to the results of assessment the list of critical raw materials for Lithuania was indentified. Results of the investigation showed that top five materials in terms of economic importance, supply and environmental country risks for Lithuanian economy are: crude oil, natural

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

  15. Import of biofuels and peat

    International Nuclear Information System (INIS)

    In areas neighbouring Sweden, i.e., foremost the Baltic States, it is probable that a large part of the available amounts will be consumed on the domestic market. Studies of the possible use of wood fuel in Estonia, Latvia and Lithuania are being made by the World Bank. Considerable investments will probably be made in the near future to replace existing coal- and oil-fired boiler plants with plants burning wood fuel. Consequently, the opportunities for exports of wood fuel will probably be small. In a global perspective, peat is used only to a limited extent as fuel. In the former Soviet Union alone it is estimated that the amount of peat that is economically feasible to extract is about 166x109 tonnes at a moisture content of 40%. Among the most interesting bio products that can be used in energy production from different food processing industries are nut-shells and fruit stones. Some stones, such as those in olives, plums and peaches, are excellent as fuels. The advantage with olive stones, in comparison with chips is that the bulk weight is high and the moisture content is low. Olive stones are thus similar to processed biofuels such as pellets. Due to their high energy content the olive stones can replace coal, which cannot be done by unprocessed fuels without expensive investments in materials handling equipment. Our survey shows that processed forest fuels and crushed olive stones are the products of greatest interest for the Swedish market. It also shows that both chips and peat-based products from the Baltic States are competitive

    When we look at our environment, we primarily pay attention to visually distinctive objects. We refer to these objects as visually important or salient. For efficient visual processing, the human visual system identifies salients objects and dedicates most of its processing resources to them. An analogous resource allocation can be performed by salient-object detection algorithms, which identify objects of interest in an image. Consequently, thanks to salient-object detection, complex visual computing operations can focus on the important parts of the visual data and can save time and resources.

    Murine typhus, caused by Rickettsia typhi, is an important zoonosis in all parts of the world. The disease is transmitted from rodents to humans by fleas. In this article we describe the first three cases of serologically proven murine typhus imported into Norway during the 1990s. The patients were Norwegian tourists who had visited respectively Guinea-Bissau, Crete and Thailand. They all became acutely ill with fever, chills and severe headache 1-10 days after return to Norway. None of them had a rash. Two patients were admitted to hospital, and one was treated with ciprofloxacin for suspected typhoid fever. All the patients recovered without sequelae. The diagnosis of murine typhus was based on detection of IgM-anti-bodies against R typhi in serum samples during reconvalescence. PMID:9265302

  13. Important plasma problems in astrophysics

    International Nuclear Information System (INIS)

    In astrophysics, plasmas occur under very extreme conditions. For example there are ultra strong magnetic fields in neutron stars) relativistic plasmas around black holes and in jets, extremely energetic particles such as cosmic rays in the interstellar medium, extremely dense plasmas in accretion disks, and extremely large magnetic Reynold's numbers in the interstellar medium. These extreme limits for astrophysical plasmas make plasma phenomena much simpler to analyze in astrophysics than in the laboratory. An understanding of such phenomena often results in an interesting way, by simply taking the extreme limiting case of a known plasma theory. I will describe one of the more exciting examples. I will attempt to convey the excitement I felt when I was first exposed to it. However, not all plasma astrophysical phenomena are so simple. There are certain important plasma phenomena in astrophysics, which have not been so easily resolved. In fact a resolution of them is blocking significant progress in astrophysical research. They have not yet yielded to attacks by theoretical astrophysicists nor to extensive numerical simulation. I will attempt to describe one of the more important of these plasma-astrophysical problems, and discuss why its resolution is so important to astrophysics. This significant example is fast, magnetic reconnection. Another significant example is the large-magnetic-Reynold's-number MHD dynamos

    It is needless to cite the importance of education for succeed of engineering. IEEJ called for the establishment of ICEE in 1994, where the education is thought highly of, though its discussion has not been well working. Generally speaking, education has been one of the most important national strategies particularly at a time of its political and economical development. The science and technology education is, of course, not the exemption. But in these days around 2000 it seems that the public pays little attention on the science and technology, as they are quite day to day matters. As the results, for instance, such engineering as power systems and electric heavy machines are referred to as “endangered”. So fur, many engineers have tried not to be involved in social issues. But currently they can not help facing with risks of social issues like patent rights, troubles and accidents due to application of high technology, information security in the use of computers and engineering ethics. One of the most appropriate ways for the risk management is to learn lessons in the past, that is, history, so that the idea suggested in it could be made full use for the risk management. The author cited the global importance of education, particularly of engineering history education for engineering ethics, in the ICEE 2010 held in Bussan, Korea, as the 16th anniversary.

  15. The efficient importation and distribution of radioisotopes. Suggestions for the most economic importation of radioisotopes

    International Nuclear Information System (INIS)

    In the course of their work in many Member States, IAEA technical assistance experts have sometimes encountered difficulties in connection with the importation of radioactive isotopes. In some countries they have been consulted as to the possible improvement of import procedures. The purpose of this publication is to summarize the experience that has been gained in the hope that it may be useful both to scientists who wish to import radioisotopes for their work and to public officials who are concerned with the administrative and financial aspects of the problem. This question is of considerable importance because many countries have only limited resources of scientific man-power and foreign exchange and hence it is essential, if these resources are to be utilized fully, that efficient importing procedures be established. Furthermore, the success or failure of technical assistance activities may depend on whether radioisotopes needed for the project can be efficiently imported. Although the data summarized in this publication are based mainly on the experience of medical users of radioisotopes, they are equally applicable to their uses in other fields such as agriculture and hydrology. This publication covers the subject of importation and distribution of radioisotopes, and concludes with a brief section on the domestic production of short-lived radioisotopes in research reactors

    Full Text Available The name maglev is derived from magnetic levitation. Magnetic levitation is a highly advanced technology. It has various uses. The common point in all applications is the lack of contact and thus no wear and friction. This increases efficiency, reduces maintenance costs, and increases the useful life of the system. The magnetic levitation technology can be used as an efficient technology in the various industries. There are already many countries that are attracted to maglev systems. Many systems have been proposed in different parts of the worlds. This paper tries to study the most important uses of magnetic levitation technology. The results clearly reflect that the maglev can be conveniently considered as a solution for the future engineering needs of the world.

    Since changes in import prices feed into consumer prices and thus might affect monetary policy decisions, policymakers need to establish whether or not German importers’ long-run pricing behaviour has changed. Of particular interest are any shifts in the importance of cost passthrough and pricing-to-market for import pricing in Germany that may have ocurred since the 1990s. We analyse pricing in single equations for 11 product categories because the factors influencing the pricing behaviour, ...

  6. Clinical importance of predicting radiosensitivity

    International Nuclear Information System (INIS)

    Full text: The optimal use of radiation therapy in cancer treatment is hampered by the application of normal tissue tolerance limits that are derived from population averages. Such limits do not reflect the considerable differences in susceptibility to radiation injury that exist among individuals. Development of assays that accurately predicted normal tissue tolerance in individual patients would permit real application of the concept of treatment to tolerance. By adjusting doses upwards or downwards to achieve a uniform probability of complication in each patient, the therapeutic ratio, i e., the probability of an uncomplicated cure, would be increased for the population as a whole. Although the pathogenesis of radiation injury is highly complex, clinical studies have demonstrated a significant correlation between the in vitro radiosensitivity of patients' fibroblasts and their risk of developing late connective tissue type complications of radiotherapy. While such assays lack the precision and practicality to be used clinically, they do establish the principle of prediction of normal tissue tolerance. Newer assays using surrogate endpoints for cell survival and incorporating insights into the effects of radiation on cellular growth, differentiation, senescence and cytokine production are being developed. Such assays may, in the future, be complemented or replaced by molecular and/or cytogenetic probes to derive robust estimates of individual tolerance. The goal of accurate prediction of individual tolerance for clinical use, while not imminent, does seem achievable

    Based on the knowledge and related theory of earth's radiation belt, the data chronous orbit were analyzed. It is proved that the observational results are in agreement with the theoretical description of the radiation belt structures. Analysis of more than 3years' data showed clearly that under quiet solar conditions, at a height of about 800 km the energetic particles were mainly located in three regions: northern auroral belt (40°-80°), southern auroral belt (-40°- -80°) and South Atlantic Geomagnetic Anomaly Region (SAA). Actually, this is for the global distribution, at each longitude the latitudinal coverage is much narrower and particles are along the geomagnetic latitude of about ±60°.The species of particles in different regions and their counting rates are different. In SAA,usually both electrons and protons are observed, which should come from inner radiation belt; in polar regions only energetic electrons are observed under the quiet condition,which belongs to the outer radiation belt. The distribution of outer radiation electrons is asymmetrical for longitudes as well as northern and southern polar regions. These asymmetries can be explained with the reflecting altitudes of the mirror points of charged particles at the same L shell.

    Full Text Available Asia has now woken up. Its huge economic development is proof of this. The Asian-Pacific nations have known how to adopt Western means of production and have incorporated them into their own culture and tradition. However, this does not mean that they are not undergoing profound transformations both at a domestic and external level, as can be highlighted, with regard to the latter, by the desire to establish a new order in the Asia-Pacific region. In this context, the present article analyses whether this dynamic presents a reformation of the world order: the fundamental role that the US plays in this region after the Cold War; the new actors and power relations that are emerging such as Japan, China and ASEAN (Association of South East Nations; and forums such as APEC (AsiaPacific Economic Cooperation, EAEC (East Asian Economic Conference, ASEAN and the ASEAN Security Forum, created and empowered among other things in order to keep a check on the reappearance of those old “ghosts” (nationalisms, territorial disputes pending solution which could triumph over the growing prosperity.Finally, the author draws to attention the Europe of the EU which is too busy in its own self-construction and puts before it the challenge of knowing how to shape itself into the third great actor of the region, after the U.S. and Japan and he speaks of the necessityfor Spain to be more present in the Pacific given that it is vital for its economy.

    The product test asks the product of a quantity index number and a price index number to equal the corresponding value change. The literature treats the product test as being so important that it is used to identify acceptable index number pairs, and to construct implicit index numbers when an otherwise desirable pair fails the test. We treat the product test as a hypothesis to be tested, and we provide an empirical application.

  12. Toxoplasmosis: An Important Protozoan Zoonosis

    Sonar S. S. and Brahmbhatt M.N.

    Full Text Available Toxoplasmosis is an important infection caused by single celled parasite Toxoplasma gondii which is one of the world's most common parasites. Toxoplasmosis is considered to be the third leading cause of death attributed to food-borne illness in the United States. Most people affected never develop signs and symptoms. But for infants born to infected mothers and for people with compromised immune systems, toxoplasmosis can cause extremely serious complications. Toxoplasmosis was first described in 1908 from a small rodent. The parasite infects almost all worm blooded animals and serological evidence indicates that it is one of the most common of humans’ infections throughout the world. The disease is transmitted mainly by ingestion of infective stage of the parasite, organ transplant as well as blood transfusion in addition to the transplacental transmission which is very common. Toxoplasmosis can be presented in various forms of clinical manifestations depending on the immune status of the patient causing life threatening disease in AIDS patient. Pregnant women, cat owners, veterinarians, abattoir workers, children, cooks, butchers are considered as high risk group. Timely treatment of man and animals with proper antibiotic, hygienic measures, proper disinfection, mass education and vaccination are the measures to curtail the disease.

  14. The importance of effective catheter securement.

    Science.gov (United States)

    Fisher, Jayne

    This article examines the importance of securing/fixing indwelling urinary catheters. The Oxford English dictionary interlinks the two words-'secure' and 'fix'-as having the same meaning. To secure the catheter should not be confused with 'support', whereby the weight of the urine drainage bag is supported with the use of velcro straps or a sleeve. The author introduces the need for the concept of this practice to be at the forefront of nurses' minds in all settings, and this is demonstrated through the use of case studies. Current guidance in this area is reviewed, as well as the problems that can arise when catheters are not secured properly and the available products for health professionals to use. PMID:20948482

  15. The importance of recent results from epidemiology

    International Nuclear Information System (INIS)

    The underground miner radon epidemiology reported in the past 15 years has led to modeling of the lung cancer risk from 222Rn exposure, quantitating the risk in present day mines, extrapolating the risk to environmental 222Rn exposure, and relating effects of low and high LET radiation. Many countries have occupational guidelines that now better conform to the actual risks experienced in mining and some have governmental guidelines regarding environmental exposure which, when fully implemented, can impose substantial benefit but also substantial cost to society. For this reason it important to follow the health of underground mining populations to better understand the risk that has been deduced, inferred or calculated. The purpose of this report is to describe the most recent results and advances. In this examination a biological basis for a new model for 222Rn decay product risk is developed

  16. Comparison of China's oil import risk. Results based on portfolio theory and a diversification index approach

    International Nuclear Information System (INIS)

    In recent years, the international oil price has fluctuated violently, bringing about huge risk for the international oil trade. In fact, the risk of crude oil and petroleum product imports is different because of the different import origins and prices. Which import risk is lower for China? From the perspective of oil supply security, how should China portfolio crude oil and petroleum product imports to minimize its oil import risk? Using portfolio theory and a diversification index approach, this paper compares and analyzes the supply, price and transport risks of crude oil and petroleum product imports. Our results show that the following: (1) Specific risk (diversification risk) and marine transport risk of China's petroleum product imports are lower than that of crude oil imports. (2) The average rate of return of China's petroleum product imports is higher than that of crude oil imports. Moreover, the average import price variance of petroleum product imports is lower than that of crude oil imports. Thus, the systematic risk (price risk) of petroleum products is lower too. Therefore, from the perspective of oil supply security, China should increase petroleum product imports to decrease its oil import risk. (author)

    Full Text Available The most important protozoan parasites in Indonesia are the malaria parasites, Toxoplasma gondii and Entamoeba histolytica. After the second world war the residual insecticides and effective antimalarial drugs were used in the control of malaria. After development of resistance among mosquitoes to insecticides, the Malaria Control Programme was switched over to the Malaria Eradication Programme. Malaria incidence dropped heavily. However, due to the quick development of vector resistance and financial limitations, malaria came back and so did the Malaria Control Programme. P. falciparum and P.vivax are the most common species in Indonesia. Important vectors are An. sundaicus, An. aconitus, An. maculatus, An. hyrcanus group, An. balabacensis, An. farauti etc. An. sundaicus and An. aconitus have developed resistance to DDT and Dieldrin in Java. In 1959 the Malaria Eradication Programme was started in Java, Bali and Lampung. In 1965 the API dropped to 0,15 per thousand. From 1966 onwards malaria transmission was on the increase, because spraying activities were slowed down, but dropped again from 1974 onwards by occasional residual house spraying with DDT or Fenitrothion, malaria surveillance and treatment of malaria cases, resulting in an API of 0.18 per thousand in 1987. At present malaria is not transmitted in Jakarta and in capitals of the provinces and kabupatens, except in Irian Jaya, Nusa Tenggara Timur and one or two other provinces, but it still exists in rural areas. The distribution of chloroquine resistant P.falciparum is patchy. Resistance is at the RI, RII and RUT levels. The main problems of malaria control are : the increasing development of resistance of the vector to insecticides, the change of An.aconitus from zoophili to anthropophili and from indoor to outdoor biting, the increasing resistance of P.falciparum to chloroquine, the shortage of skilled manpower and limitation of budget. In Indonesia many newborns with congenital

  20. Global Grazing Systems: Their Continuing Importance in Meeting Global Demand

    Animal production exerts significant demand on land, water and food resources and is an extensive means by which humans modify natural systems. Demand for animal source foods has more than tripled over the past 50 years due to population growth and dietary change. To meet this demand, livestock intensification (e.g. concentrated animal feeding operations) has increased and with it the water, nitrogen and carbon footprints of animal production. However, grass-fed systems continue to contribute significantly to overall animal production. To date, little is known about the contributions of grass- and grain-fed systems to animal calorie production, how this has changed through time and to what extent these two systems are sensitive to climate. Using a calorie-based approach we hypothesize that grain-fed systems are increasing in importance (with serious implications for water and nutrient demand) and that rangeland productivity is correlated with rainfall. Our findings show that grass-fed systems made up the majority of animal calorie production since 1960 years but that the relative contribution of grain-fed system has increased (from 27% to 49%). This rapid transition towards grain-fed animal production is largely a result of changing diets demand, as we found the growth of grass-fed production only kept pace with population growth. On a regional scale, we find that Asia has been the major contributor to the increase in grass-fed animal calorie production and that Africa has undergone the most drastic transition from grass-fed to grain-fed dependence. Finally, as expected we see a positive relationship between rangeland productivity and precipitation and a shift from dairy- to meat-dominated production going from drier to wetter climates. This study represents a new means of analyzing the food security of animal products and an important step in understanding the historic trends of animal production, their relation to climate, their prospects for the future and their
