    Full Text Available Recent debates concerning organic food systems have focused on the conventionalization hypothesis, which posits that the organic food sector has become increasingly bifurcated between “historical” players in the organic movement on one side, and on the other by distributors and industrial operators recently arrived in the sector, who practice a more conventionalized form of organic agriculture which is now on the ascendancy. The most prominent explanations for the growth and dominance of a conventionalized organic food system have been economic, based in the logics of input costs, especially land rent. We use the cases of the Belgian Blue commodity system and the Belgian organic beef commodity system to argue that conventionalization is also cognitive. To understand the role of cognition in the ascendance of the conventional organic food sector, we utilize the concept of “référentiel” – or system of cognitive references – as developed by Muller and Jobert. We believe that comparing organic and conventional practices as two systems of cognitive references makes a deeper understanding of conventionalization possible in two ways: first because it makes it clear that the two systems coexist on a cognitive level, understood in a broad sense as tightly knit sets of knowledge, beliefs, standards, and images. Secondly, the concept of “referential” enables one to understand how the conventional system can become irreversible (lock-in effect and thus incompatible with the development of the organic system.

  5. Energy Optimized Envelope for Cold Climate Indoor Agricultural Growing Center

    Full Text Available This paper presents a study of the development of building envelope design for improved energy performance of a controlled indoor agricultural growing center in a cold climate zone (Canada, 54° N. A parametric study is applied to analyze the effects of envelope parameters on the building energy loads for heating, cooling and lighting, required for maintaining growing requirement as obtained in the literature. A base case building of rectangular layout, incorporating conventionally applied insulation and glazing components, is initially analyzed, employing the EnergyPlus simulation program. Insulation and glazing parameters are then modified to minimize energy loads under assumed minimal lighting requirement. This enhanced design forms a base case for analyzing effects of additional design parameters—solar radiation control, air infiltration rate, sky-lighting and the addition of phase change materials—to obtain an enhanced design that minimizes energy loads. A second stage of the investigation applies a high lighting level to the enhanced design and modifies the design parameters to improve performance. A final part of the study is an investigation of the mechanical systems and renewable energy generation. Through the enhancement of building envelope components and day-lighting design, combined heating and cooling load of the low level lighting configuration is reduced by 65% and lighting load by 10%, relative to the base case design. Employing building integrated PV (BIPV system, this optimized model can achieve energy positive status. Solid Oxide Fuel Cells (SOFC, are discussed, as potential means to offset increased energy consumption associated with the high-level lighting model.

  13. Potential use of a chemical leaching reject from a kaolin industry as agricultural fertilizer Uso potencial do resíduo químico lixiviado duma indústria de caulim como adubo de terras agrícolas

    2007-10-01

    Full Text Available The industrial refining of kaolin involves the removal of iron oxides and hydroxides along with other impurities that cause discoloration of the final product and depreciate its commercial value, particularly undesirable if destined to the paper industry. The chemical leaching in the industrial processing requires treatments with sodium hyposulfite, metallic zinc, or sulfuric and phosphoric acids, in order to reduce, dissolve and remove ferruginous compounds. To mitigate the environmental impact, the acidic effluent from the leaching process must be neutralized, usually with calcium oxide. The resulting solid residue contains phosphorous, zinc, and calcium, among other essential nutrients for plant growth, suggesting its use as a macro and micronutrient source. Samples of such a solid industrial residue were used here to evaluate their potential as soil fertilizer in an incubation greenhouse experiment with two soil samples (clayey and medium-textured. The small pH shift generated by applying the residue to the soil was not a limiting factor for its use in agriculture. The evolution of the concentrations of exchangeable calcium, and phosphorous and zinc extractability by Mehlich-1 extractant during the incubation period confirms the potential use of this industrial residue as agricultural fertilizer.O beneficiamento industrial do caulim envolve a remoção de óxidos e hidróxidos de ferro e outras impurezas, que conferem coloração indesejável ao produto final e depreciam seu valor comercial, particularmente se destinado à indústria de papel. A lixiviação química, na linha de processamento industrial, pode ser feita com tratamentos com hipossulfito de sódio, zinco metálico e ácidos sulfúrico e fosfórico, para redução, solubilização e remoção de compostos ferruginosos. A fim de minimizar o impacto ambiental, o efluente ácido, procedente da etapa de lixiviação, deve ser inicialmente neutralizado, usualmente por óxido de c

    The report entitled Climate Change Impacts and Adaptation : A Canadian Perspective, presents a summary of research regarding the impacts of climate change on key sectors over the past five years as it relates to Canada. This chapter on agriculture describes how climate change will affect primary agriculture production in Canada with particular focus on potential adaptation options, and vulnerability of agriculture at the farm level. Agriculture is a vital part of the Canadian economy, although only 7 per cent of Canada's land mass is used for agricultural purposes due to the limitations of climate and soils. Most parts of Canada are expected to experience warmer conditions, longer frost-free seasons and increased evapotranspiration. The impacts of these changes on agriculture will vary depending on precipitation changes, soil conditions, and land use. Northern regions may benefit from longer farming seasons, but poor soil conditions will limit the northward expansion of agricultural crops. Some of the negative impacts associated with climate change on agriculture include increased droughts, changes in pest and pathogen outbreaks, and moisture stress. In general, it is expected that the positive and negative impacts of climate change would offset each other. 74 refs., 2 tabs., 1 fig

    Fragmentation of natural habitats is a central concern of biodiversity conservation and is considered a significant factor contributing to species loss and populations decline. We studied this in Cotové Agricultural Center in the municipality of Santa Fe de Antioquia (Colombia),where the conversion of natural forests to different land use systems, has limited the amount of available habitat. With the aim to describe the effect of habitat loss on bird presence in five land uses (fruiting trees, silvopastoral systems, secondary forest, pasture low density of trees and grass cutting) in this area, we studied bird diversity using two methods: fixed point counts and mist nets to analyze the influence of land use in the composition, richness and abundance of birds present were studied. A total of 6633 individuals of 101 species were observed of which 11 species were migratory. The insectivorous and frugivorous foraging guilds were better represented. The Shannon index indicated the highest values of alpha diversity for the silvopastoral system, and the fruit with the lowest. The grazing and silvopastoral land systems shared more species with low tree density. The importance of the environmental heterogeneity found is highlighted as a positive factor for bird species richness, mostly of low and middle habitat specificity, and preferably from edge habitats and open areas. In order to preserve natural regeneration and connectivity between different land use types, and to promote stability of bird species populations, some management actions should be implemented in the area.

    Ola Zetterquist

    2011-05-01

    Full Text Available The article analyses the fundamental constitutional enigma of the European Union (EU, namely whether the EU can be considered as a (from its Member States separate and independent constitutional legal order. The EU is often referred to as a legal order sui generis, i.e. of a unique character that defies traditional definitions. More specifically, the notion of an independent and separate EU is at odds with the idea of the sovereign state. The notion of the EU as a legal order sui generis is too much influenced by the models of the sovereign state and sovereignty (in the vein of Thomas Hobbes. The key component in the Hobbesian idea of sovereignty is freedom as non-interference. A sovereign state is consequently a state that is free from, i.e. not interfered with by, external actors like, for example, the EU. Put differently, either the EU is sovereign or the Member States are sovereign. By shifting the perspective to a neo-Roman republican understanding of freedom as non-domination the constitutional picture of the EU will become more nuanced. Res publica is best understood as what citizens hold in common and above their narrow self-interest. According to a republican notion of the constitution the purpose of the law is to eliminate the possibility of arbitrary domination. For that reason, not all interference is to be considered as a restriction of freedom but only those restrictions that cannot be justified according to the res publica. Viewed through the republican prism it can be argued that the EU represents an important advancement in securing freedom as non-domination without implying that the EU must become a state. The fundamental enigma can thus be rephrased as a clash between two diverging concepts of freedom. Whereas the EU will always be at odds with the idea of sovereignty (however framed it will be much easier to reconcile with the republican ideal.

    Today, urban agriculture is one of the most widely used sustainability strategies to improve the metabolism of a city. Schools can play an important role in the implementation of sustainability master plans, due their socio-educational activities and their cohesive links with families; all key elements in the development of urban agriculture. Thus, the main objective of this research is to develop a procedure, in compact cities, to assess the potential installation of rooftop greenhouses (RTGs) in schools. The generation of a dynamic assessment tool capable of identifying and prioritizing schools with a high potential for RTGs and their eventual implementation would also represent a significant factor in the environmental, social, and nutritional education of younger generations. The methodology has four-stages (Pre-selection criteria; Selection of necessities; Sustainability analysis; and Sensitivity analysis and selection of the best alternative) in which economic, environmental, social and governance aspects all are considered. It makes use of Multi-Attribute Utility Theory and Multi-Criteria Decision Making, through the Integrated Value Model for Sustainability Assessments and the participation of two panels of multidisciplinary specialists, for the preparation of a unified sustainability index that guarantees the objectivity of the selection process. This methodology has been applied and validated in a case study of 11 schools in Barcelona (Spain). The social perspective of the proposed methodology favored the school in the case-study with the most staff and the largest parent-teacher association (social and governance indicators) that obtained the highest sustainability index (S11); at a considerable distance (45%) from the worst case (S3) with fewer school staff and parental support. Finally, objective decisions may be taken with the assistance of this appropriate, adaptable, and reliable Multi-Criteria Decision-Making tool on the vertical integration and

    Buchanan, B J; Filkins, J P

    1976-07-01

    The intravascular removal rates of colloidal carbon and of biologically active endotoxin by the reticuloendothelial system (RES) were evaluated as a function of blood-glucose levels. There was a significant negative correlation of carbon clearance half time on blood glucose in both saline-treated and insulin-treated rats. Insulin hypoglycemia depressed RES carbon clearance with the maximal effect occurring at blood glucose values below 30 mg/dl. Insulin hypoglycemia also severely impaired the intravascular removal of endotoxin as evaluated by lethality bioassay in lead-sensitized rats. It is concluded that blood glucose may modulate RES phagocytic function and that the hypoglycemia of endotoxin shock may augment the shock state due to impairment of RES host defense clearance functions.

    Full Text Available Com a realização deste trabalho, avaliou-se a qualidade física, química e bioquímica do percolado produzido em colunas de resíduo sólido urbano recém-coletado (RSU, contendo ou não camada de resíduo de construção civil (RCC, com fins de aproveitamento agrícola; para isso, o RSU foi colocado, de forma seqüencial em camadas de 0,15 m de espessura e peso específico de 7 kN m-3, obtidas por compressão do material acondicionado, formando-se ao final duas colunas com 2,47 m de altura. Em uma das colunas, antes do acondicionamento do RSU, foi disposta uma camada de 0,30 m de RCC, como base para a coluna. Amostras do percolado lixiviado das colunas foram coletadas quinzenalmente para a realização das seguintes caracterizações: CE, pH, ST, SST, DQO, DBO, N total, Ca, Mg, Fe, Mn, Cd, Cu, Zn, Pb, Ni e Cr. Com base nos relativamente altos valores de pH e de concentrações de material orgânico e macronutrientes (N, Ca, Mg e de baixas concentrações de metais pesados, o uso dos percolados de aterros sanitários deve ser considerado como forma viável de disposição final dessa água residuária.This study aimed to evaluate the physical, chemical and biochemical characteristics of the percolate produced by recently collected solid residue (RSU columns with or without residue layer from building demolition (RCC. For this, the RSU was sequentially conditioned in layers of 0.15 m and 7 kN m-3 density to obtain two columns of 2.47 m height. One of the columns received a RCC 0.30 cm layer, positioned at its base. Samples of the leachate were collected every fifteen days for the following characterization: pH, EC and concentration of TS, TSS, COD, BOD, total N, Ca, Mg, Fe, Mn, Cd, Cu, Zn, Pb, Ni and Cr. The presence of the RCC layer in the columns provided no alterations in EC, but caused a decrease in concentrations of BOD, COD, TOC, TS, TSS, Ca, Mn and Fe in the leachate.

    Full Text Available The present work aimed to investigate the antioxidant properties of byproducts derived from wine production. The varieties of PINOT GRIS and COUDERC 13 grapes, collected in Videira-SC, were analyzed as natural sources of polyphenols and other prophylactic agents (antioxidants for application in food and phytochemical industries. The biomass used for extracts was ground and dried in different temperatures (45oC, 60oC e 80oC, using acetone 80% as solvent. The phenolic compounds were quantitatively evaluated by the Folin-Ciocalteu method and the results expressed in mg/100g of Gallic acid. For the flavonoids analysis, it was applied DMACA (p- Dimethylaminocinnamaldehye method and the results were expressed in equivalent mg of catechin/100g sample. The antioxidant activity was evaluated by spectrophotometric method through the discoloration of ABTS•+ radical (2,2'-azino-bis[3- ethylbenzthiazoline-6-sulfonic acid] with potassium persulphate and by DPPH method, which is based on the reduction of DPPH• radical absorbance by antioxidant substances; the results were expressed in TEAC (antioxidant activity equivalent to Trolox and VCEAC (antioxidant activity equivalent to vitamin C. It was observed a better antioxidant activity on extracts obtained from PINOT GRIS grapes, in which the 45 oC dried extracts presented a higher number of phenolic compounds and flavonoids, as well as a better antioxidant activity in both varieties. These information become useful for phenolic compounds identifying and for a possible using of these extracts as a secure additive in food industry.Este trabalho propõe uma investigação do potencial antioxidante do resíduo no processamento de uvas das variedades COUDERC 13 e PINOT GRIS, ambas coletadas em Videira-SC, como fonte natural de polifenóis e outros agentes profiláticos (antioxidantes para aplicação nas indústrias alimentícia e de fitoterápicos.

  20. RES: Regularized Stochastic BFGS Algorithm

    Science.gov (United States)

    Mokhtari, Aryan; Ribeiro, Alejandro

    2014-12-01

    RES, a regularized stochastic version of the Broyden-Fletcher-Goldfarb-Shanno (BFGS) quasi-Newton method is proposed to solve convex optimization problems with stochastic objectives. The use of stochastic gradient descent algorithms is widespread, but the number of iterations required to approximate optimal arguments can be prohibitive in high dimensional problems. Application of second order methods, on the other hand, is impracticable because computation of objective function Hessian inverses incurs excessive computational cost. BFGS modifies gradient descent by introducing a Hessian approximation matrix computed from finite gradient differences. RES utilizes stochastic gradients in lieu of deterministic gradients for both, the determination of descent directions and the approximation of the objective function's curvature. Since stochastic gradients can be computed at manageable computational cost RES is realizable and retains the convergence rate advantages of its deterministic counterparts. Convergence results show that lower and upper bounds on the Hessian egeinvalues of the sample functions are sufficient to guarantee convergence to optimal arguments. Numerical experiments showcase reductions in convergence time relative to stochastic gradient descent algorithms and non-regularized stochastic versions of BFGS. An application of RES to the implementation of support vector machines is developed.

    Full Text Available Este estudo avaliou a contaminação por ovos de helmintos, cistos e oocistos de protozoários em compostos orgânicos utilizando lodo de esgoto doméstico e resíduos agropecuários. Foram realizadas análises parasitológicas em amostras de 25 diferentes compostos orgânicos, antes e após tratamento térmico a 60°C durante 12 horas. Os resultados demonstraram elevada contaminação parasitária em todos os compostos analisados antes do tratamento e a não redução dessa contaminação após o tratamento térmico. A identificação das larvas obtidas em coproculturas antes e após o tratamento térmico dos compostos indicou que os gêneros mais freqüentemente observados foram Cooperia e Trichostrongylus, que são nematóides gastrintestinais de ruminantes. Estes resultados demonstram que ovos de helmintos podem permanecer viáveis mesmo após o processo de compostagem e o tratamento térmico. Os compostos produzidos com lodo de esgoto doméstico e resíduo agropecuários, utilizando esses processos de tratamentos, podem constituir riscos de contaminação para humanos e animais.This research aimed at evaluating the cysts, oocysts and eggs contamination before and after thermal treatment of 60°C for 12 hours, in 25 different organic composts produced with biosolids from domestic waste-water treatment and animal and agricultural residues. The results showed high parasitological contamination for all organic composts before the treatment and these contaminations were not reduced after thermic treatment. The larva identification in coprocultures before and after thermic treatment showed Cooperia spp. and Trichostrongylus spp. were the most prevalent nematodes. These results demonstrated that helmintus’ eggs can remain viable even after the composing and thermic treatment. The obtained composition with sewage sludge and agricultural residues through these treatment processes can establish contamination risks for humans and animals.

  4. Hi-Res scan mode in clinical MDCT systems: Experimental assessment of spatial resolution performance.

    The introduction of a High-Resolution (Hi-Res) scan mode and another associated option that combines Hi-Res mode with the so-called High Definition (HD) reconstruction kernels (referred to as a Hi-Res/HD mode in this paper) in some multi-detector CT (MDCT) systems offers new opportunities to increase spatial resolution for some clinical applications that demand high spatial resolution. The purpose of this work was to quantify the in-plane spatial resolution along both the radial direction and tangential direction for the Hi-Res and Hi-Res/HD scan modes at different off-center positions. A technique was introduced and validated to address the signal saturation problem encountered in the attempt to quantify spatial resolution for the Hi-Res and Hi-Res/HD scan modes. Using the proposed method, the modulation transfer functions (MTFs) of a 64-slice MDCT system (Discovery CT750 HD, GE Healthcare) equipped with both Hi-Res and Hi-Res/HD modes were measured using a metal bead at nine different off-centered positions (0-16 cm with a step size of 2 cm); at each position, both conventional scans and Hi-Res scans were performed. For each type of scan and position, 80 repeated acquisitions were performed to reduce noise induced uncertainties in the MTF measurements. A total of 15 reconstruction kernels, including eight conventional kernels and seven HD kernels, were used to reconstruct CT images of the bead. An ex vivo animal study consisting of a bone fracture model was performed to corroborate the MTF results, as the detection of this high-contrast and high frequency task is predominantly determined by spatial resolution. Images of this animal model generated by different scan modes and reconstruction kernels were qualitatively compared with the MTF results. At the centered position, the use of Hi-Res mode resulted in a slight improvement in the MTF; each HD kernel generated higher spatial resolution than its counterpart conventional kernel. However, the MTF along the

    2014-01-01

    Relative equilibria (REs) and relative periodic orbits (RPOs) are ubiquitous in symmetric Hamiltonian systems and occur, for example, in celestial mechanics, molecular dynamics, and rigid body motion. REs are equilibria, and RPOs are periodic orbits of the symmetry reduced system. Relative Lyapunov...... center bifurcations are bifurcations of RPOs from REs corresponding to Lyapunov center bifurcations of the symmetry reduced dynamics. In this paper we first prove a relative Lyapunov center theorem by combining recent results on the persistence of RPOs in Hamiltonian systems with a symmetric Lyapunov...... center theorem of Montaldi, Roberts, and Stewart. We then develop numerical methods for the detection of relative Lyapunov center bifurcations along branches of RPOs and for their computation. We apply our methods to Lagrangian REs of the N-body problem....

    The environmental risk assessment of the veterinary pharmaceutical ivermectin is receiving significant attention. This paper assesses the capacity of the MS{center_dot}3 soil microcosm as a tool for targeting the environmental impact assessment of veterinary drugs, using ivermectin as model. Two screening MS{center_dot}3 were performed using different European soils; one with a soil collected in an agricultural station near to Madrid, Spain and a second with a soil collected in a farm area close to York, UK. Soils were fortified with ivermectin at the following ranges: 0.01-10 mg kg{sup -}1 and 0.1-100 mg kg{sup -}1 in the Madrid and York studies, respectively. The effects on earthworms, plants and soil microorganisms were assessed in the Madrid soil. Toxicity tests on aquatic organisms (algae, cladocerans and in vitro fish cell line RTLW1) were also conducted with the leachates. No effects were observed in earthworms and plants at any tested concentration; reduction in the respiration rate (< 5%) of soil microorganisms was detected. Earthworm/soil bioconcentration factors decreased with the increase in soil concentrations and were higher for the York soil. Effects on daphnids were observed in tested leachates; based on measured levels of ivermectin in the leachates an EC50 of about 0.5{mu}gL{sup -}1 can be estimated. Comparisons based on toxicity data and equilibrium partitioning confirmed that the main risk is expected to be related to the high sensitivity of cladocerans. The results confirm that MS{center_dot}3 systems are cost-effective tools for assessing the impact of veterinary pharmaceuticals when applied to agricultural land, as previously demonstrated for antimicrobials.

    Water and sediment samples were collected from June through October 2007 from seven plots at the Rutgers Agricultural Research and Extension Center in Upper Deerfield, New Jersey, and analyzed for a suite of pesticides (including fungicides) and other physical and chemical parameters (including sediment mineralogy) by the U.S. Geological Survey. Plots were selected for inclusion in this study on the basis of the crops grown and the pesticides used. Forty-one pesticides were detected in 14 water samples; these include 5 fungicides, 13 herbicides, 1 insecticide, and 22 pesticide degradates. The following pesticides and pesticide degradates were detected in 50 percent or more of the groundwater samples: 1-amide-4-hydroxy-chorothalonil, alachlor sulfonic acid, metolachlor oxanilic acid, metolachlor sulfonic acid, metalaxyl, and simazine. Dissolved-pesticide concentrations ranged from below their instrumental limit of detection to 36 micrograms per liter (for metolachlor sulfonic acid, a degradate of the herbicide metolachlor). The total number of pesticides found in groundwater samples ranged from 0 to 29. Fourteen pesticides were detected in sediment samples from continuous cores collected within each of the seven sampled plots; these include 4 fungicides, 2 herbicides, and 7 pesticide degradates. Pesticide concentrations in sediment samples ranged from below their instrumental limit of detection to 34.2 nanograms per gram (for azoxystrobin). The total number of pesticides found in sediment samples ranged from 0 to 8. Quantitative whole-rock and grain-coating mineralogy of sediment samples were determined by x-ray diffraction. Whole-rock analysis indicated that sediments were predominantly composed of quartz. The materials coating the quartz grains were removed to allow quantification of the trace mineral phases present.

    2017-04-01

    BonaRes is short for "soil as a sustainable resource for the bioeconomy". It is funded by the German Federal Ministry of Education and Research (BMBF) under the umbrella of the National Research Strategy BioEconomy 2030. BonaRes consists of ten interdisciplinary research project consortia and the 'BonaRes - Centre for Soil Research' (see also Wollschläger et al 2016). It is one task of the BonaRes Data Centre as part of the 'BonaRes - Centre for Soil Research', to collect data and meta-data of agricultural long-term field experiments (LTFE) in Germany. The definition of LTFE in the context of BonaRes is a minimum duration of twenty years and a static design. LTFE are essential research infrastructures for agricultural sciences and soil sciences amongst other disciplines. Some LTFE run since a very long time; the start of the oldest one in Germany was 1878. Therefore, in many cases valuable time series exist. Data sets of LTFE shall be compiled and made publicly available by the BonaRes Data Centre. The public availability together with an easy access will lead to an enhanced usability of the data. This probably makes the LTFE itself more valuable through an improved visibility and may also help to maintain the LTFE. Beyond the data compilation there is the possibility for every data owner to make a data publication, which offers an additional value for the data owner after his first right of use. A first step towards a joint database is a compilation of all existing LTFE in Germany with meta information to each trial. This information is shown in an interactive web map, what is completely new in that context. Besides the exact position of the LTFE the following metadata are shown: name of the LTFE, website (if available), institution, land use category, participation in existing networks, research theme, start (and maybe end) of the trial, and research parameters. Details on the meta information will be presented in the speech. Literature Wollschläger, U; Helming

    Urban agriculture is crucial to local populations, but the risk of it contaminating water has rarely been documented. The aim of this study was to assess pesticide contamination of surface waters from the Méfou watershed (Yaoundé, Cameroon) by 32 selected herbicides, fungicides, and insecticides (mainly polar) according to their local application, using both grab sampling and polar organic compounds integrative samplers (POCIS). Three sampling campaigns were conducted in the March/April and October/November 2015 and June/July 2016 rainy seasons in urban and peri-urban areas. The majority of the targeted compounds were detected. The quantification frequencies of eight pesticides were more than 20% with both POCIS and grab sampling, and that of diuron and atrazine reached 100%. Spatial differences in contamination were evidenced with higher contamination in urban than peri-urban rivers. In particular, diuron was identified as an urban contaminant of concern because its concentrations frequently exceeded the European water quality guideline of 0.200 μg/L in freshwater and may thus represent an ecological risk due to a risk quotient > 1 for algae observed in 94% of grab samples. This study raises concerns about the impacts of urban agriculture on the quality of water resources and to a larger extent on the health of the inhabitants of cities in developing countries.

    Farmers’ views on research and extension services (RES) included in the Agricultural Knowledge and Innovation System are rarely investigated. This study analyses the relationship between key factors of innovation behaviour (market orientation, learning orientation, and innovation attitude) and the use of RES through structural equation modelling, focusing on small-scale agricultural holdings. Market orientation and learning orientation appear to be positively correlated, confirming that synergies between both factors provide a background for innovativeness. Learning orientation and farm-holders’ education level, improve knowledge exchange and make the agriculture innovation process more inclusive. However, farmers’ innovation attitude is not clearly correlated with the use of RES. Motivations about “the will to do innovations” are represented by a construct that does not appear to have a determinant effect as a mediator in farmer’s decisions about using RES.

    Greenhouse crop evolution if from one hand improves the quality of products and productive cycles, from another hand cause negative effects on the natural resources, the environment and the economy of the country. Although renewable energies already feature to some extent in the European Union's regional, the 2007-2013 Structural Funds package could be the occasion to increase the weight given to RES within the energy programmes for less favoured regions (particularly in ex-objective 1 areas). In those areas, greenhouse crop sector is particularly developed as agriculture industrial activity. According to numerous investigations, agricultural greenhouse consumption for greenhouse acclimatization represents approximately between 2% to 6% of the E U's-27 total energy consumption. This report is intended to give a general overview to the potential of renewable energy and technology in Italy, particularly geothermal, wind and solar (thermic and photovoltaic) as energy for greenhouse crop sector. RES have a high potential for developing of indigenous resources, service activities, new job creation and reducing Co2 emissions. [it

  11. CoRes utilization for building PCK in pre-service teacher education on the digestive system topic

    Nugraha, Ikmanda

    2017-05-01

    Knowledge of teachers in learning activities in the classroom has a close relationship with how well and how much students learn. Recently, a promising development in teacher education has appeared that centers on the academic construct of pedagogical content knowledge (PCK). This study was an exploratory study into a science teacher education program that seeks to build the foundations on which pre-service teachers can begin to build their pedagogical content knowledge (PCK). The program involved the use of Content Representations (CoRes), which was initially applied as component of a strategy for exploring and gaining insights into the PCK of in-service science teachers. This study involved the researcher and 20 students (third year) in a pre-service teacher education course (School Science I) in science education when the students worked to make content analysis on the digestive system topic. During the course, the students make their own CoRes through a workshop for digestive system topic individually, in pairs and whole class discussion. Data were recorded from students' CoRes, student reflective journals, interviews, and field notes recorded in the researcher's reflective journal. Pre-service teachers' comments from interviews and reflective journals were coded in relation to references about: (1) the effectiveness of variety strategies in building the knowledge bases required to design a CoRes and (2) their awareness and/or development of tentative components of future PCK for a digestive system topic as a result of CoRes construction. Observational data were examined for indications of increasing independence and competency on the part of student teachers when locating appropriate information for designing their CoRes. From this study, it is hoped that the pre-service science teachers are able to build knowledge and then transform it into a form of PCK for digestive system topic for their first classroom planning and teaching to teach digestive system

    This paper presents an extensive analysis of the Greek electricity market for the next 7-year period (2014–2020) based on an hour-by-hour simulation considering five different RES technologies, namely wind, PV, small hydro, biomass and CHP with emphasis on PV integration. The impact of RES penetration on the electricity market operation is evaluated under two different models regarding the organization of the Greek wholesale day-ahead electricity market: a mandatory power pool for year 2014 (current market design) and a power exchange for the period 2015–2020 (Target Model). An integrated software tool is used for the simulation of the current and the future day-ahead market clearing algorithm of the Greek wholesale electricity market. Simulation results indicate the impact of the anticipated large-scale RES integration, in conjunction with each market model, on specific indicators of the Greek electricity market in the long-term. - Highlights: • Analysis of the Greek electricity market for the next 7-year period (2014–2020) based on hour-by-hour simulation. • Five different RES technologies are considered with emphasis on PV integration. • A power pool (for 2014) and a power exchange (for 2015–2020) are considered. • Various market indicators are used for the analysis of the impact of the RES integration on the Greek electricity market. • Two alternative tariff schemes for the compensation of the new ground-mounted PV units from 2015 onwards are investigated

    The strong in-plane anisotropy of rhenium disulfide (ReS 2 ) offers an additional physical parameter that can be tuned for advanced applications such as logic circuits, thin-film polarizers, and polarization-sensitive photodetectors. ReS 2 also presents advantages for optoelectronics, as it is both a direct-gap semiconductor for few-layer thicknesses (unlike MoS 2 or WS 2 ) and stable in air (unlike black phosphorus). Raman spectroscopy is one of the most powerful characterization techniques to nondestructively and sensitively probe the fundamental photophysics of a 2D material. Here, we perform a thorough study of the resonant Raman response of the 18 first-order phonons in ReS 2 at various layer thicknesses and crystal orientations. Remarkably, we discover that, as opposed to a general increase in intensity of all of the Raman modes at excitonic transitions, each of the 18 modes behave differently relative to each other as a function of laser excitation, layer thickness, and orientation in a manner that highlights the importance of electron-phonon coupling in ReS 2 . In addition, we correct an unrecognized error in the calculation of the optical interference enhancement of the Raman signal of transition metal dichalcogenides on SiO 2 /Si substrates that has propagated through various reports. For ReS 2 , this correction is critical to properly assessing the resonant Raman behavior. We also implemented a perturbation approach to calculate frequency-dependent Raman intensities based on first-principles and demonstrate that, despite the neglect of excitonic effects, useful trends in the Raman intensities of monolayer and bulk ReS 2 at different laser energies can be accurately captured. Finally, the phonon dispersion calculated from first-principles is used to address the possible origins of unexplained peaks observed in the Raman spectra, such as infrared-active modes, defects, and second-order processes.

    Since its beginnings, the Agricultural Area had a selected research team involved in the development of different agricultural techniques. Currently, there are two main branches engaged in the solution of agricultural problems: Soil fertility and induced mutations. Soil fertility: Within this branch, studies on soil nutrients and availability of water and light resources, have been made by using isotope methods. In the near future studies on nitrogen and potassium content in potato, rice and wheat plantations will be held. Induced mutations: The main objective of this team is to obtain through radioinduced mutations, as well as in vitro growth, improved rice and other cereal seeds to be used under hostile environmental conditions. The further goal will be to develop new genotypes straight from the mutants or by utilization of this material as breeding materials in interchange programs

    Although there were not reasons to deplore against major activity release from any of the 110 industrial reactors authorized to operate in US, the nuclear incident that occurred at the Three Mile Island Plant in 1979 urged the public conscience toward the necessity of readiness to cope with events of this type. The personnel of the Emergency Planning Office functioning in the frame of US Department of Agriculture has already participated in around 600 intervention drillings on a federal, local or state scale to plan, test or asses radiological emergency plans or to intervene locally. These exercises allowed acquiring a significant experience in elaborating emergency plans, planning the drillings, working out scenarios and evaluation of the potential impact of accidents from the agricultural point of view. We have also taken part in different international drillings among which the most recent are INEX 1 and RADEX 94. We have found on these occasions that the agricultural problems are essential preoccupations in most of the cases no matter if the context is international, national, local or of state level. The paper poses problems specifically related to milk, fruits and vegetables, soils, meat and meat products. Finally the paper discusses issues like drilling planning, alarm and notification, sampling strategy, access authorizations for farmers, removing of contamination wastes. A number of social, political and economical relating problems are also mentioned

  5. Agriculture and environmental pollution

    Agriculture came into existence about 15,000 years ago and passed through different stages of food gathering, hunting, hoe culture and sedentary agriculture followed by modem agriculture. It began simultaneously in five world centers concentrating on different crops, most suited to those areas. It was also effected by changes in climate influenced by temperature, drought and magnitude of precipitation, which determined the distribution of populations and occupation of the people. With the increase in population the need for food also progressively increased, necessitating introduction of modern agriculture to enhance production. The indiscriminate and faulty use of advanced technology has added its share in the, destruction of environment. The two approaches that contributed to this were horizontal wand vertical expansion. The former results in deforestation, desertification, soil erosion, land salting and water logging as well as the frequent occurrence of droughts and famines, the latter destroyed soil structure and fertility through decreased microbial populations, fish culture, wildlife and bird sanctuaries, in addition to hazards in human beings and fauna. The real culprit of this global devastation is the high population growth rate, which needs to be contained at safer levels, coupled with sensible use of inputs to produce needed quantities of food and fiber.

    Enhanced in 2014, the energy and climate goals for 2030 of the European Union require the mobilization of everyone, everywhere. In a dynamic set to intensify rural territories, as well as cities, the communities have a major role to play. As the principal trustees of renewable resource deposits, they are the vanguard of the energy transition. Their strengths? Wind and water in abundance (very often), the sun of course, biomass - agricultural, forest, woodland, domestic, food processing - geothermal energy. With the desire to make this renewable capital live, it made some decide to take or regain control of the energy issue, reduce their energy bills and those of their inhabitants. Attracted by the opportunity to revitalize local economies and rural communes (alone or in groups) they are more likely to want to become 100% RES. But how to move from intention to action when faced with the lack of knowledge, or means, or when you feel too small to act? It is to assist you in developing your energy policy that this guide was written. Pragmatic, practical, it brings together the return on experience from partners and communities involved in 100% RES Communities project. For three years, elected representatives from rural areas, some experienced and some less, together with experts from 10 countries in Europe, have sought the best organizational, technical and financial means to reduce consumption and produce renewable energy. If because of the administrative, cultural, economic differences within the Union, all the territories do not enjoy the same facilities, the 100% RES Communities project has defined pragmatic methods, practices and tools which will make your work easier. You will find in this guide the key steps in defining your strategy and building your action plan. This is a feasible action plan to be shared and implemented with the stakeholders. A final note: because it is within networks that we discover new solutions, which can replenish the practices and

    The most recent EU member states seem to have important Renewable Energy Sources (RES) potential. However, they have serious structural difficulties in development and integration of RES policies. Indeed, the balanced development of RES between the member states is urgent today. The penetration of the RES in these member states is related to the existence of an appropriate environment (political, economical, social, and technological). The current paper is based on an analytical review and specific PEST analysis aiming to assess the current RES environment and the progress so far in each of these most recent EU members. (author)

    2013-06-01

    This report summarises the outcomes of a 30 months duration continuing education project entitled 'Urban Planners with Renewable Energy Skills' (UP-RES). The project was carried out by a multi-disciplinary international consortium with the aim of informing planners and related professionals about energy-efficient and CO{sub 2} reducing technologies, practices and systems that can be developed across urban areas to serve whole communities. This report provides an overview of the key issues: The overall project approach to devising a training program based on preceding training needs analysis The key tasks involved in creating the training materials The marketing of the training as well as evaluation results Best practise examples of RES in urban planning. The UP-RES project has focused on several major target groups. These include those groups directly involved in taking forward renewable energy projects for whom the UP-RES training was principally focused; those who wish to deliver such training programmes; and policy makers who are ultimately responsible for the decisions that govern how widely such technologies will be implemented. Each of these groups has its own perspective concerning renewable energy technologies so the report is structured accordingly: For professionals involved in implementation: Among those professions that are likely to become involved with renewable energy initiatives in urban areas are urban planners, architects, energy suppliers, developers, building owners, and consulting engineers. For these professionals chapters 3.2 (summary of training need analysis) and 4 (best practise examples) are most likely to appeal. For training experts and organisations: Training programmes that address the relevance of renewable energies in urban areas require a comprehensive set of materials. As an example of how to organise training courses and lessons learnt, chapter 3 might be interesting. For the generally interested: Renewable energies are

    2016-10-01

    Full Text Available Japan's agriculture provides only a part from the population's needs, in caloric terms Japan must impute 60% of foods. Arable land are few, but are worked very performant, rice being the main crop together with cotton, citrus, sugarcane, wheat, potato, soybean, sugar beet, other vegetables. Widely is practiced sericulture and fisheries, Japan being one of the leading producers of silk from the world and having over 600 ports specialized for fishing. Japanese agriculture has remained behind the industry and services, this trend being manifested after the very high economic growth from 1960-1970. The main focus of the movements from the Japanese cooperative system is represented by the creation of large specialized farms through the replacing of the traditional ones. The most important task of agricultural cooperatives from Japan is meeting the consumption needs of its members. Integrated leadership of Japanese cooperatives of farmers act at all levels, primary, at prefecture level and at national level. Contractual relationships play a decisive role in the integration of Japanese farmers. In Japan there are about 840 agricultural cooperatives very well organized with a balanced planning and efficiently conducted, agricultural cooperative MIKABI being the most developed, mainly focused on the production of mandarins. In Japan there are three large distribution centers of agricultural products, 29 distribution markets controlled by the prefecture and 1,000 local markets. Organization of cooperatives is the pyramid system on three levels: local, prefecture and national (National Federation of Agricultural Cooperatives.

    2013-01-01

    The massive deployment of renewable energy sources represents a high priority for Greece in order to comply with the Directive 2009/28/EC on the promotion of the use of energy from renewable sources by 2020. In this perspective, Aegean islands especially Lesvos, are endowed with a considerable potential of a portfolio of renewables, a fact that the entrepreneurial interest has already been targeted. However, regulatory attempts for a massive penetration of renewables do not take seriously into account preferences and risk perceptions of local communities where the proposed projects are to be installed. The aim of this study is to investigate individual preferences and social values towards specific technologies of renewables in Lesvos island. We apply an open-ended contingent valuation survey in order to analyze factors shaping public attitudes towards a portfolio of renewable technologies and estimate the economic welfare (Willingness To Pay) of the preferred technologies. We argue that such information is relevant for energy policy design and the establishment of effective measures for the promotion of renewable energy sources. - Highlights: ► We investigate individual preferences and attitudes towards a portfolio of RES technologies. ► We elicit public acceptance for investing in specific RES technologies. ► We analyze factors shaping public preferences of the preferred technologies. ► We estimate the economic welfare of the preferred technologies

    masculinity and horsemanship conveys the impression that women had nothing to do with horses. This is true for many situations. The circus arena, however, seems to have been an exception as women could perform there. At the heart of the performances was not only equestrianism, but also the notion of gender......The purpose of this article is to analyse gender relations in equestrianism from the beginning of the 19th to the first decades of the 20th century. Focus will be on the female horse riding circus artists, the écuyères. The fact that women were circus riders at this time is interesting as in many....... It is even likely that ”doing gender” was an indispensable part of the show, as the allure of the écuyères depended on the embodiment and presentation of seemingly incompatible features: beauty, grace and femininity as well as mastery of an art that was a traditionally male domain....

  15. A novel protein-protein interaction in the RES (REtention and Splicing) complex.

    The retention and splicing (RES) complex is a conserved spliceosome-associated module that was shown to enhance splicing of a subset of transcripts and promote the nuclear retention of unspliced pre-mRNAs in yeast. The heterotrimeric RES complex is organized around the Snu17p protein that binds to both the Bud13p and Pml1p subunits. Snu17p exhibits an RRM domain that resembles a U2AF homology motif (UHM) and Bud13p harbors a Trp residue reminiscent of an UHM-ligand motif (ULM). It has therefore been proposed that the interaction between Snu17p and Bud13p resembles canonical UHM-ULM complexes. Here, we have used biochemical and NMR structural analysis to characterize the structure of the yeast Snu17p-Bud13p complex. Unlike known UHMs that sequester the Trp residue of the ULM ligand in a hydrophobic pocket, Snu17p and Bud13p utilize a large interaction surface formed around the two helices of the Snu17p domain. In total 18 residues of the Bud13p ligand wrap around the Snu17p helical surface in an U-turn-like arrangement. The invariant Trp(232) in Bud13p is located in the center of the turn, and contacts surface residues of Snu17p. The structural data are supported by mutational analysis and indicate that Snu17p provides an extended binding surface with Bud13p that is notably distinct from canonical UHM-ULM interactions. Our data highlight structural diversity in RRM-protein interactions, analogous to the one seen for nucleic acid interactions. © 2014 by The American Society for Biochemistry and Molecular Biology, Inc.

  16. ResDE Two-Component Regulatory System Mediates Oxygen Limitation-Induced Biofilm Formation by Bacillus amyloliquefaciens SQR9.

    Efficient biofilm formation and root colonization capabilities facilitate the ability of beneficial plant rhizobacteria to promote plant growth and antagonize soilborne pathogens. Biofilm formation by plant-beneficial Bacillus strains is triggered by environmental cues, including oxygen deficiency, but the pathways that sense these environmental signals and regulate biofilm formation have not been thoroughly elucidated. In this study, we showed that the ResDE two-component regulatory system in the plant growth-promoting rhizobacterium Bacillus amyloliquefaciens strain SQR9 senses the oxygen deficiency signal and regulates biofilm formation. ResE is activated by sensing the oxygen limitation-induced reduction of the NAD + /NADH pool through its PAS domain, stimulating its kinase activity, and resulting in the transfer of a phosphoryl group to ResD. The phosphorylated ResD directly binds to the promoter regions of the qoxABCD and ctaCDEF operons to improve the biosynthesis of terminal oxidases, which can interact with KinB to activate biofilm formation. These results not only revealed the novel regulatory function of the ResDE two-component system but also contributed to the understanding of the complicated regulatory network governing Bacillus biofilm formation. This research may help to enhance the root colonization and the plant-beneficial efficiency of SQR9 and other Bacillus rhizobacteria used in agriculture. IMPORTANCE Bacillus spp. are widely used as bioinoculants for plant growth promotion and disease suppression. The exertion of their plant-beneficial functions is largely dependent on their root colonization, which is closely related to their biofilm formation capabilities. On the other hand, Bacillus is the model bacterium for biofilm study, and the process and molecular network of biofilm formation are well characterized (B. Mielich-Süss and D. Lopez, Environ Microbiol 17:555-565, 2015, https://doi.org/10.1111/1462-2920.12527; L. S. Cairns, L. Hobley, and

    2015-06-01

    Full Text Available Biodynamic agriculture is undoubtedly the oldest organized agricultural movement in the world. It is considered as an organic agricultural farming approach and determined as the oldest organized alternative agricultural movement in the world. In 1924 Rudolf Steiner – an Austrian natural scientist and philosopher, carried out a series of eight lectures in Koberwitz, currently Kobierzyce- Poland, where he formulated his visions on changes in agriculture and revealed his spiritual and scientific concepts about the connection between nature and agriculture by determining the important role of agriculture for the future of humanity and thus he became known as “the father of anthroposophy”. The great ecological effect of the application of the biodynamic agriculture is expressed in soil preservation and preservation of the living organisms in the soil, as well as maintenance of the natural balance in the vegetable and animal kingdom.

The authors of these narratives resist the dominant biomedical interpretation of their impairments, but also demonstrate their dependency upon others--social, medical, or familial others. Second, in writing these narratives, the authors are also engaged in an act of identity formation, which sometimes challenge and sometimes embrace the label of disability. By telling their stories in the middle of the action of their lives--in media res, taking up or resisting the label of disability-they also demonstrate the way in which lives can be lived open to new possibilities and interpretations.

    Batlle, C.; Pérez-Arriaga, I.J.; Zambrano-Barragán, P.

    2012-01-01

    Drawing from relevant experiences in power systems around the world, this paper offers a review of existing policy support mechanisms for RES-E, with a detailed analysis of their regulatory implications. While recent studies provide an account of current RES-E support systems, in this paper we focus on some of the impacts these mechanisms have on the overall energy market structure and its performance. Given the rising importance of RES-E in systems everywhere, these impacts should no longer be overlooked. - Highlights: ► This paper offers a critical review of RES-E support mechanisms and their regulatory implications. ► The discussion focuses on how the different schemes impact the performance of the energy markets. ► We propose to redesign of current RES-E mechanisms to optimize incentives and market performance. ► Our recommendation is also to gradually move from price-based mechanisms to auctions.

  17. RES hyperphagocytosis by rats with streptozotocin-induced diabetes mellitus.

    Science.gov (United States)

    Cornell, R P

    1981-03-01

    In contrast to previous studies of neutrophils from diabetic animals and humans in vitro and of macrophages from diabetic humans in vivo, which reported phagocytic depression, reticuloendothelial system (RES) hyperphagocytosis of colloidal carbon was observed in rats at 14 and 28 days after diabetes induction with streptozotocin (STZ). Carbon clearance half times were significantly enhanced to 6.3 +/- 0.79 and 8.1 +/- 1.04 min at 14 and 28 days post-STZ, respectively, compared with the nondiabetic value (12.7 +/- 0.98 min). The severity of uncontrolled STZ-induced diabetes in rats was confirmed by significant hypoinsulinemia, hyperglucagonemia, hyperglycemia, and hyperlipidemia. Although body weights of STZ-diabetic animals declined progressively, liver weights as a percent of body weight increased above the control value at 14 and 28 days post-STZ. In fact, expression of carbon phagocytosis as the corrected phagocytic index, which accounts for changes in liver and spleen weights relative to body weight, eliminated the significant difference between STZ-diabetic and nondiabetic animals. Antibiotic treatment of diabetic rats failed to alter the hyperphagocytosis, implying that a chronic bacterial infection was not the cause of phagocytic stimulation. Daily insulin replacements, but not a single large insulin dose to 14-day post-STZ rats, reversed the enhanced phagocytosis of colloidal carbon.

    The paper presents the design features, the energy modelling and optical performance details of two pilot Intelligent Energy Buildings, (IEB). Both are evolution of the Zero Energy Building (ZEB) concept. RES innovations backed up by signal processing, simulation models and ICT tools were embedded into the building structures in order to implement a new predictive energy management concept. In addition, nano-coatings, produced by TiO2 and ITO nano-particles, were deposited on the IEB structural elements and especially on the window panes and the PV glass covers. They exhibited promising SSP values which lowered the cooling loads and increased the PV modules yield. Both pilot IEB units were equipped with an on-line dynamic hourly solar radiation prediction model, implemented by sensors and the related software to manage effectively the energy source, the loads and the storage or the backup system. The IEB energy sources covered the thermal loads via a south façade embedded in the wall and a solar roof which consists of a specially designed solar collector type, while a PV generator is part of the solar roof, like a compact BIPV in hybrid configuration to a small wind turbine.

There are a great number of instruments and ways of intervention...... in agricultural policy and they have different functions and impacts. Market price support and deficiency payments are two very important instruments in agricultural policy; however, they belong to two different support regimes or support systems.

  1. Cardiovascular Small Heat Shock Protein HSPB7 Is a Kinetically Privileged Reactive Electrophilic Species (RES) Sensor.

    2018-02-08

    Small heat shock protein (sHSP)-B7 (HSPB7) is a muscle-specific member of the non-ATP-dependent sHSPs. The precise role of HSPB7 is enigmatic. Here, we disclose that zebrafish Hspb7 is a kinetically privileged sensor that is able to react rapidly with native reactive electrophilic species (RES), when only substoichiometric amounts of RES are available in proximity to Hspb7 expressed in living cells. Among the two Hspb7-cysteines, this RES sensing is fulfilled by a single cysteine (C117). Purification and characterizations in vitro reveal that the rate for RES adduction is among the most efficient reported for protein-cysteines with native carbonyl-based RES. Covalent-ligand binding is accompanied by structural changes (increase in β-sheet-content), based on circular dichroism analysis. Among the two cysteines, only C117 is conserved across vertebrates; we show that the human ortholog is also capable of RES sensing in cells. Furthermore, a cancer-relevant missense mutation reduces this RES-sensing property. This evolutionarily conserved cysteine-biosensor may play a redox-regulatory role in cardioprotection.

  2. Hydrogen-induced structural transition in single layer ReS2

    2017-09-01

    By performing density functional theory-based calculations, we investigate how structural, electronic and mechanical properties of single layer ReS2 can be tuned upon hydrogenation of its surfaces. It is found that a stable, fully hydrogenated structure can be obtained by formation of strong S-H bonds. The optimized atomic structure of ReS2H2 is considerably different than that of the monolayer ReS2 which has a distorted-1T phase. By performing phonon dispersion calculations, we also predict that the Re2-dimerized 1T structure (called 1T {{}\\text{R{{\\text{e}}2}}} ) of the ReS2H2 is dynamically stable. Unlike the bare ReS2 the 1T {{}\\text{R{{\\text{e}}2}}} -ReS2H2 structure which is formed by breaking the Re4 clusters into separated Re2 dimers, is an indirect-gap semiconductor. Furthermore, mechanical properties of the 1T {{}\\text{R{{\\text{e}}2}}} phase in terms of elastic constants, in-plane stiffness (C) and Poisson ratio (ν) are investigated. It is found that full hydrogenation not only enhances the flexibility of the single layer ReS2 crystal but also increases anisotropy of the elastic constants.

In Latvia this volume is the highest, while in Estonia and Lithuania it is half as high. One of the factors that determine the RES-E production volumes is support policies, which in the Baltic States are different. The main objective of this work was to analyze and compare these support policies. The results have shown that for rapid RES-E development the most effective policy is to be market-oriented (as in Estonia, whereas for more stable development such policy should be producer-oriented (as in Lithuania.

    In order to achieve cost-effective RES-E deployment it is often argued that technology-neutral support schemes for renewables are indispensable. Against this background, RES-E support policies making widely use of technology differentiation in remuneration settings, e.g. across the EU, are frequently criticized from a theoretical point of view. However, in this paper we provide a systematic critique of the technology neutrality concept as a foundation for designing policy support schemes in the RES-E technology field. Specifically, the main objective of the paper is to scrutinize the arguments for technology-neutrality, and discuss three conceptual arguments for why technology-specific support schemes could in fact help minimize the societal costs of reaching future RES-E targets. We also briefly address different political economy concerns, which could constrain the choice of cost-effective policy support schemes, and that have to be taken into account for economic policy advice. For empirical illustration of the key arguments we refer to the case of German RES-E policy-making. The central conclusion from this paper is that technology-specific RES-E support schemes may generate significant economic benefits, particularly if technology markets work imperfectly and in second-best policy settings with additional non-internalized market failures. - Highlights: • Three theoretical cost-effectiveness reasons for technology-specific RES-E support. • German case study to show relevance of theoretical arguments for policy-making. • Political economy constraints to technology-neutral support are demonstrated. • Technology-specific RES-E support may generate significant economic benefits.

    A tight mask seal is frequently difficult to obtain and maintain during single-rescuer bag-valve-mask (BVM) ventilation. The ResMed mask (Bella Vista, NSW, Australia) is a continuous-positive-airway-pressure mask (CM) designed for noninvasive ventilation. In this study, we compared the ventilation performances of a standard mask (SM) and a ResMed CM using a simulation manikin in an out-of-hospital single-rescuer BVM ventilation scenario. Thirty emergency medical technicians (EMTs) performed two 2-minute attempts to ventilate a simulation manikin using BVM ventilation, alternatively, with the SM or the ResMed CM in a randomized order. Ventilation parameters including tidal volume and peak airway pressure were measured using computer analysis software connected to the simulation manikin. Successful volume delivery was defined as delivery of 440-540 mL of tidal volume in accord with present cardiopulmonary resuscitation guidelines. BVM ventilation using the ResMed CM produced higher mean (± standard deviation) tidal volumes (452 ± 50 mL vs. 394 ± 113 mL, p = 0.014) and had a higher proportion of successful volume deliveries (65.3% vs. 26.7%, p < 0.001) than that using the SM. Peak airway pressure was higher in BVM ventilation using the ResMed CM (p = 0.035). Stomach insufflation did not occur during either method. Twenty-nine of the participants (96.7%) preferred BVM ventilation using the ResMed CM. BVM ventilations using ResMed CM resulted in a significantly higher proportion of successful volume deliveries meeting the currently recommended range of tidal volume. Clinical studies are needed to determine the value of the ResMed CM for BVM ventilation.

  13. Revisiting long-run relations in power markets with high RES penetration

    2016-01-01

    Electricity generation from renewable energy resources (RES) has become increasingly significant to reach EU and emissions reduction targets. At the same time, one of the main EU policy goals has been the creation of a common internal energy market for Europe. In this paper, we focus on these two issues previously studied separately, considering their possible interactions. We first analyze the long-run relationship between day-ahead electricity prices and fuel prices (natural gas and coal) looking at two samples of years characterized by low and high RES penetration, then we explore the integration of EU markets. We show that the electricity–fuel nexus found over 2006–2008 changed dramatically over 2010–2014 for the majority of countries considered. In particular, the long-run dependence of electricity from gas and coal prices is much lower in recent years. Furthermore, our results confirm that the considered EU countries are becoming less integrated as RES-E increases. Our findings suggest that nationally implemented policies to support renewables are successful in increasing RES penetration, but they have lessened the linkage among EU markets, then making integration more difficult to obtain. - Highlights: •RES lower the intra-daily electricity dependence from coal and natural gas. •RES affect the EU wholesale electricity market integration, studied at hourly level. •Overlapping national and supranational policies tackle the achievement of EU targets. •Strong policy coordination is required to avoid that the “greens” promote the “dirtiest”.

    The purpose of this study was to determine the mastery of Content Representation (CoRes) teachers related to the integration of technology and pedagogy in teaching Biology (TPACK). This research uses a descriptive method. The data were taken using instruments CoRes as the primary data and semi-structured interviews as supporting data. The subjects were biology teacher in class X MIA from four schools in Bandung. Teachers raised CoRes was analyzed using a scoring rubric CoRes with coding 1-3 then categorized into a group of upper, middle, or lower. The results showed that the two teachers in the lower category. This results means that the control of teachers in defining the essential concept in the CoRes has not been detailed and specific. Meanwhile, two other teachers were in the middle category. This means that the ability of teachers to determine the essential concepts in the CoRes are still inadequate so that still needs to be improved.

    In this paper, we present the formation of large-size rhenium disulfide (ReS2) films via the sulfurization of Re films deposited on sapphire substrates. The effects of sulfurization temperature and pressure on the crystal quality were investigated. A [001]-oriented single crystal of ReS2 films with 6 × 10 mm2 area was realized. By sulfurizing Re films at 1100 °C, ReS2 films with well-defined sharp interfaces to c-plane sapphire substrates could be formed. Below and above the sulfurization temperature of 1100 °C, incomplete sulfurization and film degradation were observed. The twofold symmetry of the monocrystalline in-plane structure composed of Re-Re bonds along with Re-S bonds pointed to a distorted 1T structure, indicating that this structure is the most stable atomic arrangement for ReS2. For a S/Re compositional ratio equal to or slightly lower than 2.0, characteristic Raman vibrational modes with the narrowest line widths were observed. The typical absorption peak of ReS2 can be detected at 1.5 eV.

    To learn more about the use of the mass media for agricultural extension, the World Bank has considered the efforts of 2 units: INADES-formation in West Africa and the Extension Aids Branch of Malawi. The INADES-formation study focuses on Cameroon but also considers work in Rwanda and the Ivory Coast. Some general conclusions emerge from a comparison of the 2 organizations. Malawi operates an extension service which reaches farmers through extension agents, through farmer training centers, and through mass media. The Extension Aids Branch (EAB) has responsibility for its media work and broadcasts 4 1/2 hours of radio each week. Its 6 regular radio programs include a general program which interviews farmers, a music request program in which the music is interspersed with farming advice, a farming family serial, and a daily broadcast of agricultural news and information. The 17 cinema vans show some agricultural films, made by EAB, some entertainment films, and some government information films from departments other than the ministry of agriculture. EAB also has a well-developed program of research and evaluation of its own work. INADES-formation, the training section of INADES, works towards social and economic development of the population. It teaches peasant farmers and extension agents and does this through running face-to-face seminars, by publishing a magazine, "Agripromo," and through correspondence courses. In 1978-79 INADES-formation enrolled some 4500 farmers and extension agents as students. Both of these organizations work to teach farmers better agriculture techniques, and both were created in response to the fact that agricultural extension agents cannot meet all the farmers in their area. Despite the similarity of objective, there are differences in methods and philosophy. The EAB works in a single country and uses a variety of mass media, with print playing a minor role. INADES-formation is an international and nongovernmental organization and its

    Agriculture is an important component of Canadian energy policy. There are many opportunities for both the production of energy from agricultural processes and the conservation of energy in agricultural production. These opportunities, as well as current practices and research in progress, are outlined in this report. Energy sources in agriculture include biomass (straw and other residues), methane production from manure, and oil and alcohol from crops. Alternate energy sources such as solar and wind power conserve conventional resources, and additional conservation opportunities exist in the use of greenhouses, waste heat and energy-efficient farming processes. Research programs and possible trends are outlined. 10 figs., 3 tabs.

    Full Text Available Agricultural business is a very specific branch which is characterized by very low financial performance while this characteristic is given mainly by external factors as market pricing of agricultural commodities on one side, and production costs of agricultural commodities on the other side. This way, agricultural enterprises recognize negative values of gross margin in the Profit and Loss Statement but positive value of operating profit after even there are items of costs which are deducted. These results are derived from agricultural production subsidies which are recognized as income in the P/L Statement. In connection with this fact, the government subsidies are a substantial component of financial performance of agricultural enterprises.Primary research proceeded on the statistical sample of one hundred agricultural companies, has shown that also other specifics influencing financial performance of these businesses exist here. In order to determine the influences, the cluster analysis has been applied at using more than 10 variables. This approach has led to construction of clusters (groups of agricultural business entities with different characteristics of the group. The objective of this paper is to identify the main determinants of financial performance of agricultural enterprises and to determine their influences under different economic characteristics of these business entities. For this purpose, the regression analysis has been subsequently applied on the groups of companies coming out from the cluster analysis. Besides the operating profit which is the main driving force of financial performance measured with the economic value added (EVA in agricultural enterprises, also capital structure and cost of capital have been observed as very strong influences on financial performance but these factors have different directions of their influence on the economic value added under different financial characteristics of agricultural

    2D transition metal dichalcogenides materials are explored as potential surface-enhanced Raman spectroscopy substrates. Herein, a systematic study of the Raman enhancement mechanism on distorted 1T (1T') rhenium disulfide (ReS 2 ) nanosheets is demonstrated. Combined Raman and photoluminescence studies with the introduction of an Al 2 O 3 dielectric layer unambiguously reveal that Raman enhancement on ReS 2 materials is from a charge transfer process rather than from an energy transfer process, and Raman enhancement is inversely proportional while the photoluminescence quenching effect is proportional to the layer number (thickness) of ReS 2 nanosheets. On monolayer ReS 2 film, a strong resonance-enhanced Raman scattering effect dependent on the laser excitation energy is detected, and a detection limit as low as 10 -9 m can be reached from the studied dye molecules such as rhodamine 6G and methylene blue. Such a high enhancement factor achieved through enhanced charge interaction between target molecule and substrate suggests that with careful consideration of the layer-number-dependent feature and excitation-energy-related resonance effect, ReS 2 is a promising Raman enhancement platform for sensing applications. © 2018 WILEY-VCH Verlag GmbH & Co.

    In this paper, we perform a systematic and rigorous study to evaluate the Ohmic nature of the top-contact formed by the monolayer ReS 2 (mReS 2 ) and metals (gold, silver, platinum, nickel, titanium, and scandium) by means of first-principles density functional theory calculations. We investigate the potential barrier, charge transfer and atomic orbital overlap at the mReS 2 -metal interface in consideration of van der Waals forces to understand how efficiently carriers could be injected from the metal contact to the mReS 2 channel. ReS 2 is physisorbed on Au and Ag, which leads to little perturbation of its electronic structures and forms a larger Schottky contact and a higher tunnel barrier at the interface. ReS 2 is chemisorbed on Ti and Sc, where the bonding strongly perturbs the electronic structures and is found to be purely Ohmic. The bonding of ReS 2 on Pt and Ni lies between these two extreme cases, demonstrating an intermediate behavior. These findings not only provide an insight into the mReS 2 -metal interfaces but may also prove to be instrumental in the future design of ReS 2 -based devices with good performance.

    Full Text Available This article seeks to understand why Colombians, compared to many other Latin Americans, have traditionally eaten so much more beef than pork. The article first pointstothe development of a culinary tradition thatfavored beef. The bulkof the argument, though, centers on the fact that, historically, beef has been substantially cheaper than pork. This price difference, in turn, is rooted in the low productivity of Colombian agriculture, which made corn, often used to fatten hogs, expensive. Additional factors that favored beef include a receding agrarian frontier, a small hog population, the various advantages of cattle, a conflictridden history of land monopolization, and the influence of lard imports and the subsequent development of a vegetable oil industry.

Some of the sustainable agricultural marketing initiatives practiced around the world are carried out through civil organizations. Furthermore; some of these initiatives have also launched by farmers, consumers, food processors and retailers. The long-term strategies to increase these initiatives should be determined due to the fact that examples of successful sustainable agricultural marketing initiatives are inadequate and cannot be spread in Turkey. In this context, first of all, the supports provided by the government to improve agricultural marketing systems, such as EU funds for rural development should be compatible with the goals of sustainable marketing. For this purpose, it should be examined whether all proposed projects related to agricultural marketing meet the social, economic, and environmental principles of sustainable marketing. It is important that supporting organizations, especially civil society organisations, should take an active role for faster dissemination and adoption of sustainable agricultural marketing practices in Turkey. These organizations may provide technical assistance in preparing successful project proposals and training to farm groups. In addition, the other organizations, such as local administrations, producers' associations, cooperatives, can contribute to the success of sustainable agricultural marketing initiatives. The use of direct marketing strategies and vertical integration attempts in sustainable agricultural marketing initiatives that will likely be implemented in Turkey is

    Full Text Available Camemberts, livarots et pont-l’évêque participent encore largement à l'identification du pays d'Auge. Entre Saint-Pierre-sur-Dives et Livarot, de nombreux hâloirs, ou pièces d’affinage, témoignent de l’importance d’une production fermière aujourd’hui révolue et souvent peu documentée. Une simple lecture architecturale de ces édifices permet cependant de déterminer quels fromages y ont été affinés. Elle remet aussi en cause les principes couramment admis concernant leur aménagement, en particulier la disposition de leurs ouvertures, et montre que les prescriptions techniques émises au XIXe siècle et relayées par les sociétés savantes, sont restées lettre morte.Camemberts, livarots and pont-l’évêque are still largely part of the characterizing components of the pays d’Auge. Between Saint-Pierre-sur-Dives and Livarot, many hâloirs or cheese maturing rooms attest the importance of that bygone and often poorly documented agricultural production. A mere architectural examination of these buildings allows us nevertheless to determine which kind of cheese had been matured in which building. It gives us also a whole new perspective on the commonly received principles about the arrangement of the buildings, especially the setting of their apertures, and points the fact that the technical prescriptions from the 19th century that have been spread through the scientific societies have had no follow-up.

    In this study, a direct sulfidation reaction of ammonium perrhenate (NH4ReO4) leading to a synthesis of rhenium disulfide (ReS2) is demonstrated. These findings reveal the first example of a simplistic bottom-up approach to the chemical synthesis of crystalline ReS2. The reaction presented here takes place at room temperature, in an ambient and solvent-free environment and without the necessity of a catalyst. The atomic composition and structure of the as-synthesized product were characterized using several analysis techniques including energy dispersive x-ray spectroscopy, x-ray photoelectron spectroscopy, x-ray diffraction, transmission electron microscopy, Raman spectroscopy, thermogravimetric analysis and differential scanning calorimetry. The results indicated the formation of a lower symmetry (1Tʹ) ReS2 with a low degree of layer stacking.

    Highlights: • The ReS_2/rGO composites have been synthesized by a facile one-pot method. • The ReS_2/rGO composites exhibit hierarchical architecture. • The ReS_2/rGO composites deliver better electrochemical performances than ReS_2. • The enhanced performance is due to porous and conductive structure of ReS_2/rGO. - Abstract: Rhenium disulfide (ReS_2), a two-dimensional (2D) semiconductor, has attracted more and more attention due to its unique anisotropic electronic, optical, mechanical properties. However, the facile synthesis and electrochemical property of ReS_2 and its composite are still necessary to be researched. In this study, for the first time, the ReS_2/reduced graphene oxide (rGO) composites have been synthesized through a facile and one-pot hydrothermal method. The ReS_2/rGO composites exhibit a hierarchical, interconnected, and porous architecture constructed by nanosheets. As anode for lithium-ion batteries, the as-synthesized ReS_2/rGO composites deliver a large initial capacity of 918 mAh g"−"1 at 0.2 C. In addition, the ReS_2/rGO composites exhibit much better electrochemical cycling stability and rate capability than that of bare ReS_2. The significant enhancement in electrochemical property can be attributed to its unique architecture constructed by nanosheets and porous structure, which can allow for easy electrolyte infiltration, efficient electron transfer, and ionic diffusion. Furthermore, the graphene with high electronic conductivity can provide good conductive passageways. The facile synthesis approach can be extended to prepare other 2D transition metal dichalcogenides semiconductors for energy storage and catalytic application.

  10. Revisiting support policies for RES-E adulthood: Towards market compatible schemes

    International Nuclear Information System (INIS)

    Huntington, Samuel C.; Rodilla, Pablo; Herrero, Ignacio; Batlle, Carlos

    2017-01-01

    The past two decades of growth in renewable energy sources of electricity (RES-E) have been largely driven by out-of-market support policies. These schemes were designed to drive deployment on the basis of specific subsidies sustained in time to allow for the larger costs as well as to limit investor risk. While these policies have proven to be effective, the way they have been designed to date has led to costly market distortions that are becoming more difficult to ignore as penetrations reach unpreceded levels. In the context of this growing concern, we provide a critical analysis of the design elements of RES-E support schemes, focusing on how they affect this trade-off between promoting and efficiently integrating RES-E. The emphasis is on the structure of the incentive payment, which in the end turns to be the cornerstone for an efficient integration. We conclude that, while needed, a well-designed and further developed capacity-based support mechanism complemented with ex-post compensations defined for reference benchmark plants, such as the mechanism currently implemented in Spain, is an alternative with good properties if the major goal is truly market integration. The approach is robust to future developments in technology cost, performance and market penetration of RES-E. - Highlights: • Market distortions due to RES support mechanisms are becoming difficult to ignore. • This paper provides a critical analysis of the design elements of RES support schemes. • The emphasis is on the structure of the incentive, key for an efficient integration. • We argue in favor of a further developed capacity-based support mechanism. • The incentive should be combined with the design of a set of reference plants.

  11. Energy and climate hand-in-hand: Financing RES-E support with carbon revenues

    In Italy, the cost of support for renewable electricity (RES-E) is largely recovered through the “A3 surcharge”, which weighs heavily on electricity bills. Using household survey data, we show the A3 surcharge is markedly regressive. Carbon taxation in the non-ETS sector is envisaged as a means to reduce CO_2 emissions cost-effectively and generate revenue to lower the A3 surcharge. A non-ETS carbon tax would be less regressive than the A3 surcharge and its cost would be more evenly distributed across households. We calculate the revenue of a €20/tCO_2 non-ETS carbon tax would have allowed a cut in the A3 surcharge of about 68% in 2011, and 39% in 2012. The impact of the carbon tax plus the reduced A3 surcharge would have been less regressive, but the cost higher for most households. The restrictions imposed in the simulations mean the results are only appropriate to render first-round effects of the reform. Policy relevance: In the vast majority of the EU Member States, the cost of RES-E support is largely paid by electricity consumers, most often through specific surcharges. Rising electricity prices are a common concern given the implications for competitiveness and equity. The Member States facing this issue could conveniently address it through environmental tax reforms consistent with the Climate and Energy Package. Replacing RES-E surcharges with carbon taxes in the non-ETS sector would permit cost-effective reduction of CO_2 emissions while allocating the cost of RES-E support more equitably. The difference in regressivity would stem from the different consumption patterns of home fuels (including electricity) and motor fuels across income distribution. A cross-country comparison of energy household budget shares proves the structural nature of this difference between home fuels and motor fuels. Moreover, the notion that electricity consumers should pay for RES-E support is questioned on the grounds that electricity is a basic necessity good and RES

As Instituições de Ensino Superior (IES são importantes fontes geradoras devido à diversidade de atividades de ensino, pesquisa e extensão realizadas no seu âmbito. Os Restaurantes Escola (RE atendem à comunidade acadêmica dos campi universitários, e caracterizam-se por produzir resíduos similares aos domésticos, mas em maior quantidade. Este estudo foi realizado com o objetivo de investigar a composição gravimétrica dos resíduos produzidos em um RE de uma IES localizada no sul do país, bem como conhecer a situação atual do gerenciamento dos resíduos. Os dados foram obtidos através da caracterização dos resíduos do RE durante cinco dias, de entrevista com os gestores responsáveis pelo estabelecimento e da observação direta no local. Averiguou-se a inexistência de um Plano de Gerenciamento dos Resíduos Sólidos no RE, bem como a ausência de práticas efetivas relacionadas ao manejo destes. A segregação dos resíduos é prejudicada devido à falta de lixeiras específicas e a sobrecarga dos funcionários quanto às atividades desempenhadas. Ao longo do período experimental foram caracterizados 547,068 Kg de resíduos, dos quais mais de 80% corresponderam à matéria orgânica. Conclui-se que o montante de resíduo orgânico gerado pode ser destinado à compostagem. Recomenda-se a implantação de uma infraestrutura adequada para o manejo dos resíduos, que pode ser feita através da elaboração e aplicação de um plano de gestão integrada dos resíduos sólidos no RE.Abstract Nowadays, the amount of waste generated and its proper final destination is one of the greatest environmental issues.

    Rhenium disulfide (ReS2) is a unique semiconducting TMD with distorted 1T structure and weak interlayer coupling. We have previously investigated its in-plane anisotropic property and electronic applications on FET and digital inverters. In this talk, we will present high responsivity phototransistors based on few-layer ReS2. Depending on the back gate voltage, source drain bias and incident optical light intensity, the maximum attainable photoresponsivity can reach as high as 88,600 A W-1, which is one of the highest value among individual two-dimensional materials with similar device structures. Such high photoresponsivity is attributed to the increased light absorption as well as the gain enhancement due to the existence of trap states in the few-layer ReS2 flakes. The existence of trap states is proved by temperature dependent transport measurements. It further enables the detection of weak signals. Our studies underscore ReS2 as a promising material for future electronic and sensitive optoelectronic applications.

  15. Distribution of costs induced by the integration of RES-E power

    Barth, Ruediger; Weber, Christoph; Swider, Derk J.

    2008-01-01

    This article focuses on the distribution of costs induced by the integration of electricity generation from renewable energy sources (RES-E). The treatment to distribute these costs on different market actors is crucial for its development. For this purpose, individual actors of electricity markets and several cost categories are identified. According to the defined cost structure, possible treatments to distribute the individual cost categories on different relevant actors are described. Finally, an evaluation of the cost distribution treatments based on an economic analysis is given. Economic efficiency recommends that clearly attributable (shallow) grid connection as well as (deep) grid costs are charged to the corresponding RES-E producer and that the RES-E producers are also charged the regulating power costs. However, deep grid integration costs should be updated to reflect evolving scarcities. Also regulating power costs should reflect actual scarcity and thus be symmetric and based on real-time prices, taking into account the overall system imbalance. Moreover, the time span between the closure of the spot market and actual delivery should be chosen as short as possible to enable accurate RES-E production forecasts

    Parity violating electron scattering has become a well established tool which has been used, for example, to probe the Standard Model and the strange-quark contribution to the nucleon. While much of this work has focused on elastic scattering, the RES-Parity experiment, which has been proposed to take place at Jefferson Laboratory, would focus on inelastic scattering in the low-Q 2 , low-W domain. RES-Parity would search for evidence of quark-hadron duality and resonance structure with parity violation in the resonance region. In terms of parity violation, this region is essentially unexplored, but the interpretation of other high-precision electron scattering experiments will rely on a reasonable understanding of scattering at lower energy and low-W through the effects of radiative corrections. RES-Parity would also study nuclear effects with the weak current. Because of the intrinsic broad band energy spectrum of neutrino beams, neutrino experiments are necessarily dependent on an untested, implicit assumption that these effects are identical to electromagnetic nuclear effects. RES-Parity is a relatively straight forward experiment. With a large expected asymmetry (∼ 0.5 x 10 -4 ) these studies may be completed with in a relatively brief period

    Full Text Available An OECD funded research was conducted where methods and processes for speeding up innovation in agriculture were assessed. A global web-based questionnaire was sent to experts in agricultural engineering, research, marketing, education and users of new technologies. Interviews of selected experts were done to deepen the analysis. The results show that considerable part of the relatively slow innovation comes from the fact that users do not trust in new technologies or that the usability of them is unacceptable. The experts suggest that education of the engineers and designers should include more elements from User-Centered Design (UCD and also User-Driven Innovation methods should be more used. As a conclusion a new ‘Dream Team’ of agricultural innovation was developed where user interaction and marketing professionals were given more roles.

    Agricultural productivity to meet growing demands of human population is a matter of great concern for all countries. Use of green compounds to achieve the sustainable agriculture is the present necessity. This review highlights the enormous use of harsh surfactants in agricultural soil and agrochemical industries. Biosurfactants which are reported to be produced by bacteria, yeasts, and fungi can serve as green surfactants. Biosurfactants are considered to be less toxic and eco-friendly and thus several types of biosurfactants have the potential to be commercially produced for extensive applications in pharmaceutical, cosmetics, and food industries. The biosurfactants synthesized by environmental isolates also has promising role in the agricultural industry. Many rhizosphere and plant associated microbes produce biosurfactant; these biomolecules play vital role in motility, signaling, and biofilm formation, indicating that biosurfactant governs plant-microbe interaction. In agriculture, biosurfactants can be used for plant pathogen elimination and for increasing the bioavailability of nutrient for beneficial plant associated microbes. Biosurfactants can widely be applied for improving the agricultural soil quality by soil remediation. These biomolecules can replace the harsh surfactant presently being used in million dollar pesticide industries. Thus, exploring biosurfactants from environmental isolates for investigating their potential role in plant growth promotion and other related agricultural applications warrants details research. Conventional methods are followed for screening the microbial population for production of biosurfactant. However, molecular methods are fewer in reaching biosurfactants from diverse microbial population and there is need to explore novel biosurfactant from uncultured microbes in soil biosphere by using advanced methodologies like functional metagenomics.

    Given the mentioned circumstances, conventional energy planning in the Canary Islands is a very complex task. The Regional Energy Plan PECAN (2007-2015) tries to correct the existing critical situation setting, among others, the ambitious goal of >25% electricity from RES (mostly wind) for 2015. In parallel to this conventional energy planning, outstanding initiatives in the distributed generation field are underway. ITC vision is that the Canarian Archipelago, given its particular characteristics (insular systems of different sizes, abundant RES potential -different sources-, important natural and biodiversity heritage, etc.), are a laboratory for testing and demonstrating new energy technologies in real conditions, as well as their commercial implementation. These new technologies include energy storage (particularly for excess RES that cannot be absorbed by the grids), development of 100% energy self- sufficiency models (with exclusive use of RES) and micro-/minigrids with high RES penetration and RES forecasting, including advanced ICTs and sustainable mobility concepts (e.g. V2G technologies). Given the high conventional generation costs and the relatively low RES costs (wind electricity production cost is less than 0.03 Euro/kWh), the Canary Islands could in the short term achieve grid parity, and in this sense pioneer the change to a RES based energy system. Models tested on the islands could be exported or extrapolated to our islands, regions of developing countries and even other regions in continental Europe. (orig.)

    Local agricultural practices in the Nordic countries have resulted in a great diversity in agriculture in the Nordic countries. The diversities mean that in the event of contamination of agricultural land by radioactive fallout the consequences may differ greatly from region to region. For crops and soils contaminated directly by radioactive fallout there are five primary causes for concern, namely: 1. short-term internal contamination of man and animals through ingestion of surface-contaminated mature crops; 2. internal contamination of crops through foliar intake; 3. contamination of mature crops from resuspended soil; 4. direct irradiation of agricultural workers; 5. internal irradiation from inhalation of resuspended soil particulates. In the short-term, most of the radionuclides likely to be released to the atmosphere in the event of an accident have a potential to cause problems in agriculture and many have the potential for causing long-term problems. Generally, the magnitude of the problems created will depend on the: deposition mechanism (wet or dry); radionuclide composition of the fallout; type of farming system (i.e. arable or dairy); type of soil (for instance organic soils are more sensitive than mineral soils with respect to radiocaesium); state of development of the crop which in turn is determined by the season of the year.

This paper introduces a general equilibrium effective rate of protection (GE-ERP) measure, which extends and generalizes earlier partial equilibrium nominal protection measures...... shares and intersectoral linkages - are crucial for determining the sign and magnitude of trade policy bias. The GE-ERP measure is therefore uniquely suited to capture the full impact of trade policies on agricultural price incentives. A Monte Carlo procedure confirms that the results are robust....... For the 15 sample countries, the results indicate that the agricultural price incentive bias, which was generally perceived to exist during the 1980s, was largely eliminated during the 1990s.

    In this paper we address two topical questions: How do the quality of governance and agricultural intensification impact on spatial expansion of agriculture? Which aspects of governance are more likely to ensure that agricultural intensification allows sparing land for nature? Using data from the Food and Agriculture Organization, the World Bank, the World Database on Protected Areas, and the Yale Center for Environmental Law and Policy, we estimate a panel data model for six South American countries and quantify the effects of major determinants of agricultural land expansion, including various dimensions of governance, over the period 1970–2006. The results indicate that the effect of agricultural intensification on agricultural expansion is conditional on the quality and type of governance. When considering conventional aspects of governance, agricultural intensification leads to an expansion of agricultural area when governance scores are high. When looking specifically at environmental aspects of governance, intensification leads to a spatial contraction of agriculture when governance scores are high, signaling a sustainable intensification process.

  16. Agricultural Leaders' Influence on the Safety Culture of Workers.

    2017-01-01

    Most US farmers are small, independent owner-operators, many of whom are exempt from safety regulation and enforcement, as well as age restrictions relative to family members performing hazardous tasks. These smaller farms account for a disproportionate share of the total fatality and injury statistics from farming incidents, contributing to an agriculture-industry death rate that is seven times greater than all occupations combined. In contrast, large agricultural enterprises that employ larger numbers of non-family workers are more regulated and more highly incentivized by economic, supply chain, and societal factors to implement cultures of safety, and are more readily influenced by agricultural opinion leaders, agribusinesses, farm organizations, and agricultural media. These agricultural influencer institutions must find ways to play more significant roles in changing the culture on operations that use only family labor. They will find willing partners in safety organizations such as the Agricultural Safety and Health Council of America (ASHCA), Agricultural Extension, and other health and safety advocates, including the National Institute for Occupational Safety and Health (NIOSH)-funded agricultural research centers. The overall workplace injury statistics for agriculture remain alarming; however, with leadership from the larger farm operations, and help from ASHCA, academia, the healthcare community, and others, the current culture of workplace safety and health in agriculture can be impacted in positive ways.

    1993-01-01

    The recommendations on the title subject are focused on the question whether advantages and disadvantages of agricultural fuels compared to fossil fuels justify the Dutch policy promotion of the use of agricultural products as basic materials for agricultural fuels. Attention is paid to energetic, environmental and economical aspects of both fuel types. Four options to apply agricultural transportation fuels are discussed: (1) 10% bio-ethanol in euro-unleaded gasoline for engines of passenger cars, equipped with a three-way catalyst; (2) the substitution of 15% methyl tertiair butyl ether (MTBE) by ethyl tertiair butyl ether (ETBE) as a substituent for lead in unleaded super plus gasoline (Sp 98) for engines of passenger cars, equipped with a three-way catalyst; (3) 50% KME (rapeseed oil ester) in low-sulfur diesel (0.05%S D) for engines of vans without a catalyst; and (4) the substitution of 0.05% S D by bio-ethanol or KME for buses with fuel-adjusted engines, equipped with a catalyst. Also the substitution by liquefied petroleum gas (LPG), compressed natural gas (CNG) or E 95 was investigated in option four. Each of the options investigated can contribute to a reduction of the use of fossil energy and the environmental effects of the use of fossil fuels, although some environmental effects from agricultural fuels must be taken into consideration. It is recommended to seriously pay attention to the promotion of agricultural fuels, not only in the Netherlands, but also in an international context. Policy instruments to be used in the stimulation of the use of such fuels are the existing European Community subsidies on fallow lands, exemption of the European Community energy levy, and the use of tax differentiation. Large-scale demonstration projects must be started to quantify hazardous emissions and to solve still existing technical problems. 8 figs., 3 tabs., refs., 4 appendices

    Fertile soils are a fundamental resource for the production of biomass and provision of food and energy. A growing world population and latest climate targets lead to an increasing demand for bio-based products which require preserving and - ideally - improving the long-term productivity of soils as a bio-economic resource. At the same time, other soil functions and ecosystem services need to be maintained: filter for clean water, carbon sequestration, provision and recycling of nutrients, and habitat for biological activity. All these soil functions result from the interaction of a multitude of physical, chemical and biological processes which are insufficiently understood. In addition, we lack understanding about the interplay between the socio-economic system and the soil system and how soil functions benefit human wellbeing, including SDGs. However, a solid and integrated assessment of soil quality requires the consideration of the ensemble of soil functions and its relation to soil management. To make soil management sustainable, we need to establish a scientific knowledge base of complex soil system processes that allows for developing models and tools to quantitatively predict the impact of a multitude of management measures on soil functions. This will finally allow for the provision of options for a site-specific, sustainable soil management. To face this challenge, the German Federal Ministry of Education and Research (BMBF) recently launched the funding program "Soil as a Sustainable Resource for the Bioeconomy - BonaRes". In a joint effort, ten collaborative projects and the coordinating BonaRes Centre are engaged to close existing knowledge gaps for a profound and systemic assessment and understanding of soil functions and their sensitivity to soil management. In BonaRes, the complete process chain of sustainable soil use in the context of a sustainable bio-economy is being addressed: from understanding of soil processes using state-of the art and

    Precipitation is a key forcing variable in hydrological modeling of floods and being able to accurately observe precipitation is extremely important in mitigating flood impacts. The Global Precipitation Measurement (GPM) Mission, launched in Feb 2014 also presents an opportunity for high-quality real-time precipitation data and improved flood warnings. The PERSIANN-CCS developed by the scientists at the Center for Hydrometeorology and Remote Sensing (CHRS) at the University of California, Irvine is one algorithm integrated in the IMERG of PMM/GPM. In this research, the high resolution coupled hydrologic/hydraulic model named HiResFlood-UCI was applied to simulate the historical 2008 Iowa flood in the Cedar River basin. HiResFlood-UCI is a coupling of the NWS's distributed hydrologic model HL-RDHM and the hydraulic model BreZo developed by the Computational Hydraulics Group at the University of California, Irvine. The model was forced with the real-time PERSIANN-CCS and NEXRAD Stage 2 precipitation data. Simulations were evaluated based on 2 criteria: hydrographs within the basin and the areal extent of the flooding. Streamflow hydrographs were compared at 7 USGS gages, and simulated inundation maps were evaluated using USDA AWiFS 56m resolution areal flood imagery. The results show reasonable simulated hydrographs compared to USGS streamflow observations when simulating with PERSIANN-CCS and NEXRAD Stage 2 as forcing inputs. The simulation driven by NEXRAD Stage 2 slightly outperforms the PERSIANN-CCS simulation as the latter marginally underestimated the observed hydrographs. The simulation in both cases shows a good agreement (0.672 and 0.727 CSI for Stage 2 and PERSIANN-CCS simulations respectively) with the AWiFS image over the most impacted area in the Cedar Rapids region. Since the PERSIANN-CCS simulation slightly underestimated the discharge, the probability of detection (0.925) is lower than that of the Stage 2 simulation (0.965). As a trade-off, the false

    2017-09-29

    The ResStock analysis tool is helping states, municipalities, utilities, and manufacturers identify which home upgrades save the most energy and money. Across the country there's a vast diversity in the age, size, construction practices, installed equipment, appliances, and resident behavior of the housing stock, not to mention the range of climates. These variations have hindered the accuracy of predicting savings for existing homes. Researchers at the National Renewable Energy Laboratory (NREL) developed ResStock. It's a versatile tool that takes a new approach to large-scale residential energy analysis by combining: large public and private data sources, statistical sampling, detailed subhourly building simulations, high-performance computing. This combination achieves unprecedented granularity and most importantly - accuracy - in modeling the diversity of the single-family housing stock.

  10. The future has come: the 100% RES driven power system is reality

    International Nuclear Information System (INIS)

    Orths, Antje; Borre Eriksen, Peter

    2016-01-01

    The Danish political energy and climate targets fixed in the RES (Renewable Energy Sources) directive require Denmark to reach a 30 % RES share of its total energy consumption in 2020. Besides, Danish national targets aim at wind power production to correspond to 50 % of domestic gross electricity consumption (status in 2015: 42 %). For 2050, the political target is to be free of fossil fuels in the whole energy sector - i.e. including transportation. The major part of variable RES in Denmark is wind energy, the remaining power consumption mainly based on biomass, gas and coal fired central power stations and local CHP plants. Some key figures: at the end of 2015, 5,076 MW wind power capacity and 783 MW of solar power capacity were installed in Denmark, with Danish peak load at ∼6.400 MW and the total electricity consumption at 33.6 TWh. Wind power is split into 3,805 MW onshore and 1.272 MW offshore installations. In 2015, wind power produced 14.1 TWh electricity (9.3 TWh onshore, 4.8 TWh offshore), which made a ∼42 % share of the Danish electricity consumption, while solar power produced 0.6 TWh. The high RES level is already today challenging the system e.g. concerning the need for flexibility on the one hand, or by pushing power plants delivering important system services out of the market on the other hand. To fulfill the political ambitions, new arrangements concerning the technical and market design incentivizing flexibility or ancillary services, such as frequency control and voltage control, are needed and currently under development. This article gives examples and illustrates the urgency by showing a real dispatch in a windy week. (authors)

    International Nuclear Information System (INIS)

    2004-01-01

    This report documents state-of-the-art methods, tools, and data for the conduct of a fire Probabilistic Risk Assessment (PRA) for a commercial nuclear power plant (NPP) application. The methods have been developed under the Fire Risk Re-quantification Study. This study was conducted as a joint activity between EPRI and the U. S. NRC Office of Nuclear Regulatory Research (RES) under the terms of an EPRI/RES Memorandum of Understanding (RS.1) and an accompanying Fire Research Addendum (RS.2). Industry participants supported demonstration analyses and provided peer review of this methodology. The documented methods are intended to support future applications of Fire PRA, including risk-informed regulatory applications. The documented method reflects state-of-the-art fire risk analysis approaches. The primary objective of the Fire Risk Study was to consolidate recent research and development activities into a single state-of-the-art fire PRA analysis methodology. Methodological issues raised in past fire risk analyses, including the Individual Plant Examination of External Events (IPEEE) fire analyses, have been addressed to the extent allowed by the current state-of-the-art and the overall project scope. Methodological debates were resolved through a consensus process between experts representing both EPRI and RES. The consensus process included a provision whereby each major party (EPRI and RES) could maintain differing technical positions if consensus could not be reached. No cases were encountered where this provision was invoked. While the primary objective of the project was to consolidate existing state-of-the-art methods, in many areas, the newly documented methods represent a significant advancement over previously documented methods. In several areas, this project has, in fact, developed new methods and approaches. Such advances typically relate to areas of past methodological debate.

    Institute of Scientific and Technical Information of China (English)

    2011-01-01

    The advantages of cooperative economic organization being the effective carrier of agricultural insurance development are analyzed. Firstly, cooperative economic organization promotes scale management and solves the problem of decentralized operation of small households. Secondly, cooperative economic organization can settle the problem of peasants’ low systematization. Thirdly, cooperative economic organization can largely reduce the costs of agricultural insurance operation. Fourthly, cooperative organization decreases moral risks as well as adverse selection to some extent. Lastly, cooperative organization, to a certain degree, reduces the risks of agricultural production and increases the insurability of agricultural risks. Meanwhile, limitations of agricultural cooperative economic organization being the carrier of agricultural insurance operation are pointed out. Firstly, cooperative economic organization has limited coverage and small size of organization, which is harmful to the diversification of agricultural risks. Secondly, cooperative economic organization lacks capital funds and its development is not standard, which is not perfect for the function exertion as a carrier. Lastly, members of professional cooperative organization have low cultural qualities, which restrict the implementation of agricultural insurance. The modes of farmers’ cooperative economic organization promoting agricultural insurance development are proposed, including mode of agricultural insurance cooperative ( mutual corporation), mode of "leading enterprises (companies) + professional cooperative organization (planting majors) + insurance" and mode of professional cooperatives serving as agricultural insurance agent. Last of all, the promoting role of agricultural insurance in agricultural cooperative economic organization is briefly illustrated.

  17. Innovative method of RES integration into the regional energy development scenarios

    Klevas, Valentinas; Biekša, Kestutis; Murauskaitė, Lina

    2014-01-01

    Scarcity or abundance of energy resources usually depends on physical and geographical conditions in the region. However, the energy flow in the region also depends on the efficient use of energy resources, the consumption rate of energy and the possibility to use local renewable and non-renewable energy resources. Production, distribution and the use of energy resources in the region are the challenges for central and local government, business and social service, customers and other stakeholders. Development of regional energy economy should be optimized according to the available energy flow in the region using a network system analysis method, which provides solutions for developing sustainable energy economy models. The network system analysis method enables to optimize the use of local and renewable resources at the regional level and reveals available local energy resources. An efficient use of available regional resources and the use of renewable energy sources (RES) should be the main goals for the development of regional energy system. RES can compete with traditional fossil fuel with the condition that all hidden aspects are revealed. The network system analysis method enables to indicate energy flows in the region as well as indicate pros and cons of using renewable energy technologies. - Highlights: • RES integration into the regional energy development scenarios is done. • Innovative process network system (PNS) analysis method is used. • PNS method is used to optimize the use of local and renewable resources. • Analysis of energy flow in region using PNS method is done

    1992-01-01

    How will increases in levels of CO 2 and changes in temperature affect food production? A recently issued report analyzes prospects for US agriculture 1990 to 2030. The report, prepared by a distinguished Task Force, first projects the evolution of agriculture assuming increased levels of CO 2 but no climate change. Then it deals with effects of climate change, followed by a discussion of how greenhouse emissions might be diminished by agriculture. Economic and policy matters are also covered. How the climate would respond to more greenhouse gases is uncertain. If temperatures were higher, there would be more evaporation and more precipitation. Where would the rain fall? That is a good question. Weather in a particular locality is not determined by global averages. The Dust Bowl of the 1930s could be repeated at its former site or located in another region such as the present Corn Belt. But depending on the realities at a given place, farmers have demonstrated great flexibility in choosing what they may grow. Their flexibility has been increased by the numerous varieties of seeds of major crops that are now available, each having different characteristics such as drought resistance and temperature tolerance. In past, agriculture has contributed about 5% of US greenhouse gases. Two large components have involved emissions of CO 2 from farm machinery and from oxidation of organic matter in soil due to tillage. Use of diesel fuel and more efficient machinery has reduced emissions from that source by 40%. In some areas changed tillage practices are now responsible for returning carbon to the soil. The report identifies an important potential for diminishing net US emissions of CO 2 by growth and utilization of biomass. Large areas are already available that could be devoted to energy crops

Man survival in the biosphere will depend on its ability of using four technologies - mechanization, fertilizers, irrigation and pest disease control. The isotopes are usefull to establish means of producing more food and to preserve it; and clains of unbearable damages to the ecosystems caused by fertilizers and pesticides are not true, are presented.

    2013-07-01

    Full Text Available La diversification des cultures est souvent présentée comme un levier d’action pour accroître la durabilité des systèmes de production agricoles. Bien raisonnée, elle favorise en effet une réduction de l’usage d’intrants extérieurs à l’exploitation – pesticides, engrais, eau – et des nuisances environnementales associées à leur utilisation excessive. À l’inverse, la simplification des systèmes de culture engagée depuis plus de 40 ans s’est accompagnée d’un recours croissant aux intrants. Cependant, malgré son intérêt pour les systèmes de production en termes de durabilité écologique mais aussi économique (répartition des risques, et son inscription dans divers plans et dispositifs incitatifs, la diversification des cultures progresse peu. Les ministères en charge de l’agriculture et de l’environnement ont donc commandé à l’INRA une étude visant à identifier les freins à la diversification des cultures en France et les leviers mobilisables, par les pouvoirs publics notamment, pour la favoriser. L’hypothèse de travail est que ces freins relèvent du fonctionnement global du système agro-industriel, et de la capacité de développement de filières valorisant les cultures de diversification. L’étude a examiné un certain nombre de cas représentatifs de la diversité des filières et notamment de leurs modes d’organisation, qui déterminent la coordination et l’engagement des acteurs économiques impliqués dans le développement d’une culture de diversification.

  17. Nuclear techniques in agriculture

    Crops provide us food grains and many other products. Demand for food and other agricultural products is increasing. There is also need for improvement of quality of the agricultural produce. There are several technologies in use for achieving the goal of increasing the quantity and quality of agricultural produce. Nuclear techniques provide us with an option which has certain advantages. The characteristics of crop plants are determined by the genetic make up of the plant. Traditionally the genetic make up was modified using conventional breeding techniques such as cross breeding to improve crops for yield, disease resistance, stress tolerance, resistance to insect pests or to improve quality. New varieties of crops are produced which replace the earlier ones and thus the demands are met. The process of development of new varieties is long and time consuming. Nuclear technique called mutation breeding provides an efficient way of breeding new varieties or improving the older ones. This technique merely enhances the process of occurrence of mutations. In nature mutations occur at a rate of approximately one in a million, while when mutations are induced using radiations such as gamma rays the efficiency of inducing mutations is enhanced. Useful mutations are selected, the mutants are evaluated and developed as a new variety. In the Nuclear Agriculture and Biotechnology Division (NA and BTD) this technique has been used to develop mutants of many crop plants. The mutants can be used to develop a variety directly or by using it in further breeding programme. Using these approaches the NA and BTD has developed 40 new varieties of crops such as groundnut, mungbean, urid, pigeon pea, mustard, soybean, sunflower, cowpea, jute. These varieties are developed in collaboration with other agricultural institutions and are popular among the farming community. The method of mutation breeding can be applied to many other crops for improvement. There is increasing interest among

    Highlights: • Guidelines for power utilities to reach specific decarbonisation targets offered. • Optimization model of RES share to be introduced into power system is proposed. • Single criteria analysis and multicriteria sustainability assessment are applied. • The optimization method has been demonstrated on a real power system. • In the considered case, HIGH RES scenario showed to be the preferable one. - Abstract: This paper provides guidelines and principles for power utilities to reach specific energy and decarbonisation targets. Method of power generation portfolio optimization, as function of sustainability and decarbonisation, along with appropriate criteria, has been proposed. Application of this optimization method has been demonstrated on a real power system – power utility JP Elektroprivreda BiH d.d. – Sarajevo (EPBiH), a typical example of South East European power system. The software tool WASP IV has been employed in the analysis, in order to define the dynamics and an optimized expansion of generation portfolio of the power system under consideration for the next period. The mid-term generation portfolio development plan for the EPBiH power system until year 2030 has been made during this research, taking into account the shutdown dynamics of existing power units and commissioning new ones, in order to provide safe supply of electric and heat energy for local consumers. Three basic scenario of renewable energy sources (RES) expansion have been analysed to reach specific RES and decarbonisation targets set for 2030, including RES share increase from the current level of 18% up to 35% (LOW RES), 45% (MID RES) and 55% (HIGH RES). Effects to the sustainability are considered through environmental, economic and social indicators. Multicriteria sustainability assessment gave an advantage to the HIGH RES, under assumption of equal weighting factors of economic and environment groups of indicators.

    A 5-yr demonstration project was conducted to determine benefits and identify harmful effects of using waste heat in condenser cooling water (90 0 F-110 0 F) for agricultural purposes. Initial phases emphasized use and evaluation of warm water for spring frost protection, irrigation, and plant cooling in summer. Row crops, and fruit and nut trees were used in the evaluation. Undersoil heating was demonstrated on a 1.2-acre soil plot. Two and one half inch plastic pipes were buried 26 in deep and 5 ft on center, connecting to 6-in. steel headers. Warm water was circulated through the grid, heating soil on which row crops were grown. Crop production was evaluated in a 22 x 55-ft plastic greenhouse constructed on a portion of the undersoil heat grid. The greatest potential benefit of waste heat use in agriculture is in the area of greenhouse soil heating. Monetary benefits from industrial waste heat appear achievable through proper management

    Substitutional doping of transition metal dichalcogenide two-dimensional materials has proven to be effective in tuning their intrinsic properties, such as band gap, transport characteristics, and magnetism. In this study, we realized substitutional doping of monolayer rhenium disulfide (ReS 2 ) with Mo via chemical vapor deposition. Scanning transmission electron microscopy demonstrated that Mo atoms are successfully doped into ReS 2 by substitutionally replacing Re atoms in the lattice. Electrical measurements revealed the degenerate p-type semiconductor behavior of Mo-doped ReS 2 field effect transistors, in agreement with density functional theory calculations. The p-n diode device based on a doped ReS 2 and ReS 2 homojunction exhibited gate-tunable current rectification behaviors, and the maximum rectification ratio could reach up to 150 at V d = -2/+2 V. The successful synthesis of p-type ReS 2 in this study could largely promote its application in novel electronic and optoelectronic devices.

J Strength Cond Res 32(1): 323-329, 2017-This study examined the possibility of using movement velocity and the perceived exertion as indicators of relative load in the bench press (BP) exercise. A total of 308 young, healthy, resistance trained athletes (242 men and 66 women) performed a progressive strength test up to the one repetition maximum for the individual determination of the full load-velocity and load-exertion relationships. Longitudinal regression models were used to predict the relative load from the average velocity (AV) and the OMNI-Resistance Exercise Scales (OMNI-RES 0-10 scale), considering sets as the time-related variable. Load associated with the AV and the OMNI-RES 0-10 scale value expressed after performing a set of 1-3 repetitions were used to construct 2 adjusted predictive equations: Relative load = 107.75 - 62.97 × average velocity; and Relative load = 29.03 + 7.26 × OMNI-RES 0-10 scale value. The 2 models were capable of estimating the relative load with an accuracy of 84 and 93%, respectively. These findings confirm the ability of the 2 calculated regression models, using load-velocity and load-exertion from the OMNI-RES 0-10 scale, to accurately predict strength performance in BP.

    The growing pressures on the world's land resources will result in problems requiring a major research effort.The first group of problems relates to increased soil degradation. The research to alleviate this will have to incorporate not only physical and biological solutions, but also pay much more attention to the socio-economic context in which the conservation programmes need to succeed.The second major area for research on land resource is to make better use of low-capacity or problem soils.This could be by reducing the existing limitations, such as changing physical or chemical characteristics of the soil, or by developing plants and production techniques which reduce the detrimental effects of constraints. Example of these are acidity, salinity, and aluminium toxicity. Finally the broadest and more important area is that of research to enable more intensive use of better-quality land. Research topics here may relate to optimal plant nutrient management, soil moisture management, and developing cultivation techniques with minimum commercial energy requirements. Making plants more productive will involve research aimed at increasing photosynthetic efficiency, nitrogen fixation, disease and pest resistance, improved weed control, and bio-engineering to adjust plant types to maximize production potentials. Improved rotational systems for the achievement of many of the above goals will become increasingly important, as the potential problems or inappropriate cultivation practices become evident. In conclusion, food supplies of the world could meet the rapidly rising demands that are made on them, if agriculture receives sufficient attention and resources. Even with most modern development, land remains the base for agriculture, and optimal use of the world's land resources is thus crucial for future agricultural production

    Anisotropic two-dimensional (2D) van der Waals (vdW) layered materials, with both scientific interest and application potential, offer one more dimension than isotropic 2D materials to tune their physical properties. Various physical properties of 2D multi-layer materials are modulated by varying their stacking orders owing to significant interlayer vdW coupling. Multilayer rhenium disulfide (ReS2), a representative anisotropic 2D material, was expected to be randomly stacked and lack interlayer coupling. Here, we demonstrate two stable stacking orders, namely isotropic-like (IS) and anisotropic-like (AI) N layer (NL, N > 1) ReS2 are revealed by ultralow- and high-frequency Raman spectroscopy, photoluminescence and first-principles density functional theory calculation. Two interlayer shear modes are observed in AI-NL-ReS2 while only one shear mode appears in IS-NL-ReS2, suggesting anisotropic- and isotropic-like stacking orders in IS- and AI-NL-ReS2, respectively. This explicit difference in the observed frequencies identifies an unexpected strong interlayer coupling in IS- and AI-NL-ReS2. Quantitatively, the force constants of them are found to be around 55-90% of those of multilayer MoS2. The revealed strong interlayer coupling and polytypism in multi-layer ReS2 may stimulate future studies on engineering physical properties of other anisotropic 2D materials by stacking orders.Anisotropic two-dimensional (2D) van der Waals (vdW) layered materials, with both scientific interest and application potential, offer one more dimension than isotropic 2D materials to tune their physical properties.

  6. Polymères en ambiance nucléaire comportement à long terme

    CERN Document Server

    Audouin, Ludmila; Fayolle, Bruno; Richaud, Emmanuel; Verdu, Jacques

    2012-01-01

    Ce livre présente des outils théoriques originaux, indispensables pour ta prédiction de la durée de vie des matériaux polymères en ambiance nucléaire. Le problème de vieillissement des polymères est avant tout un problème d'ingénieur, dont la préoccupation majeure est la prédiction de durée de vie selon des critères pertinents du point de vue de l'application. Partant de ce constat, les auteurs ont focalisé leur intérêt sur les aspects les plus souvent négligés dans les ouvrages classiques mais cruciaux : la modélisation cinétique de l'oxydation radio-amorcée à faible débit de dose et les conséquences de l'irradiation sur les propriétés thermomécaniques. Ces deux aspects font l'objet de développements qui confèrent à l'ouvrage son originalité, lui permettant d'être un complément utile aux ouvrages classiques. Présenté de manière claire et pédagogique, cet ouvrage permettra à l'étudiant de Master, au jeune chercheur comme à l'ingénieur de rejoindre un courant de reche...

  7. COMMUNITY SUPPORTED AGRICULTURE (CSA

    Full Text Available Farms of CSA types are a viable alternative to trade of agricultural products coming from conventional agriculture. These farms are faced with a number of policy issues related to product, price, distribution and promotion. In order to elucidate the issues listed above, we have investigated the literature of specialty. Farmers must make more flexible the content of basket both quantitatively and in terms of the nature of food products offered. Consumers need information on ways of preparation or preservation of products. The growth of the processing degree in farm, and inclusion in the offer of services in ecotourism represent effective options to satisfy consumers. To offset the negative impact of high prices measures should be taken in reducing costs, more flexibility in rescheduling of payments due from customers and compensate for the lack of financial resources with the provision of farm work or subsidize a portion of the basket value from private or government sources. Delivery of baskets should be both at fixed points and at customers domicile. Farmers must provide customers the possibility so that they could harvest themselves the products they will buy. Negative influence of prices will be reduced by establishing an effective communication policy with the market, by organizing events on the farm or nearby towns, through blogs and social networks, and through participation in fairs and exhibitions. A greater customer involvement in farming activities will lead to the implementation of an effective marketing mix.

    Global support for Conservation Agriculture (CA) as a pathway to Sustainable Intensification is strong. CA revolves around three principles: no-till (or minimal soil disturbance), soil cover, and crop rotation. The benefits arising from the ease of crop management, energy/cost/time savings, and soil and water conservation led to widespread adoption of CA, particularly on large farms in the Americas and Australia, where farmers harness the tools of modern science: highly-sophisticated machines, potent agrochemicals, and biotechnology. Over the past 10 years CA has been promoted among smallholder farmers in the (sub-) tropics, often with disappointing results. Growing evidence challenges the claims that CA increases crop yields and builds-up soil carbon although increased stability of crop yields in dry climates is evident. Our analyses suggest pragmatic adoption on larger mechanized farms, and limited uptake of CA by smallholder farmers in developing countries. We propose a rigorous, context-sensitive approach based on Systems Agronomy to analyze and explore sustainable intensification options, including the potential of CA. There is an urgent need to move beyond dogma and prescriptive approaches to provide soil and crop management options for farmers to enable the Sustainable Intensification of agriculture.

  14. HiRes camera and LIDAR ranging system for the Clementine mission

    Energy Technology Data Exchange (ETDEWEB)

    Ledebuhr, A.G.; Kordas, J.F.; Lewis, I.T. [and others

    1995-04-01

    Lawrence Livermore National Laboratory developed a space-qualified High Resolution (HiRes) imaging LIDAR (Light Detection And Ranging) system for use on the DoD Clementine mission. The Clementine mission provided more than 1.7 million images of the moon, earth, and stars, including the first ever complete systematic surface mapping of the moon from the ultra-violet to near-infrared spectral regions. This article describes the Clementine HiRes/LIDAR system, discusses design goals and preliminary estimates of on-orbit performance, and summarizes lessons learned in building and using the sensor. The LIDAR receiver system consists of a High Resolution (HiRes) imaging channel which incorporates an intensified multi-spectral visible camera combined with a Laser ranging channel which uses an avalanche photo-diode for laser pulse detection and timing. The receiver was bore sighted to a light-weight McDonnell-Douglas diode-pumped ND:YAG laser transmitter that emmitted 1.06 {micro}m wavelength pulses of 200 mJ/pulse and 10 ns pulse-width, The LIDAR receiver uses a common F/9.5 Cassegrain telescope assembly. The optical path of the telescope is split using a color-separating beamsplitter. The imaging channel incorporates a filter wheel assembly which spectrally selects the light which is imaged onto a custom 12 mm gated image intensifier fiber-optically-coupled into a 384 x 276 pixel frame transfer CCD FPA. The image intensifier was spectrally sensitive over the 0.4 to 0.8 {micro}m wavelength region. The six-position filter wheel contained 4 narrow spectral filters, one broadband and one blocking filter. At periselene (400 km) the HiRes/LIDAR imaged a 2.8 km swath width at 20-meter resolution. The LIDAR function detected differential signal return with a 40-meter range accuracy, with a maximum range capability of 640 km, limited by the bit counter in the range return counting clock.

    As global populations continue to increase, agricultural productivity will be challenged to keep pace without overtaxing important environmental resources. A dynamic and integrated approach will be required to solve global food insecurity and position agriculture on a trajectory toward sustainability. Genetically modified (GM) crops enhanced through modern biotechnology represent an important set of tools that can promote sustainable agriculture and improve food security. Several emerging biotechnology approaches were discussed in a recent symposium organized at the 13th IUPAC International Congress of Pesticide Chemistry meeting in San Francisco, CA, USA. This paper summarizes the innovative research and several of the new and emerging technologies within the field of agricultural biotechnology that were presented during the symposium. This discussion highlights how agricultural biotechnology fits within the context of sustainable agriculture and improved food security and can be used in support of further development and adoption of beneficial GM crops.

    Full Text Available Financial institutions present on the market become more attentive when they have to give loans to the agriculture sector. The lack of necessary guarantees the low profit registered in agricultural district, economy instability and other things had and continue to have a negative impact on the evolution of agricultural sector, this being seen as one with a high level of risk. Commercial banks use less own funds for lending to agriculture and especially when the loans are guaranteed from various funds, programs or foreign donor agencies. Farmers find it difficult to bank loans because of collateral amount required is too high. However, commercial banks in Moldova provide agricultural loans, thus increasing the economic efficiency of agriculture.

    The mission of the Sustainable Bioenergy Development Center (SBDC) is to enhance the capability of America’s bioenergy industry to produce transportation fuels and chemical feedstocks on a large scale, with significant energy yields, at competitive cost, through sustainable production techniques. Research within the SBDC is organized in five areas: (1) Development of Sustainable Crops and Agricultural Strategies, (2) Improvement of Biomass Processing Technologies, (3) Biofuel Characterization and Engine Adaptation, (4) Production of Byproducts for Sustainable Biorefining, and (5) Sustainability Assessment, including evaluation of the ecosystem/climate change implication of center research and evaluation of the policy implications of widespread production and utilization of bioenergy. The overall goal of this project is to develop new sustainable bioenergy-related technologies. To achieve that goal, three specific activities were supported with DOE funds: bioenergy-related research initiation projects, bioenergy research and education via support of undergraduate and graduate students, and Research Support Activities (equipment purchases, travel to attend bioenergy conferences, and seminars). Numerous research findings in diverse fields related to bioenergy were produced from these activities and are summarized in this report.

    Full Text Available Botswana, a middle-income country, is experiencing a sluggish economic growth and a rapid urbanisation which has brought in its wake high unemployment, poverty and food insecurity. This has led some people to engage in subsistence and commercial urban and peri-urban agriculture (UPA to address these problems. However, in spite of its known advantages, uptake of UPA has been low for a number of reasons including: high GDP before the economic meltdown of recent years; a harsh climate; lack of water; poor access to land; and over-reliance on generous government handouts. Nevertheless, the extent of its practice and its contribution to food security – albeit modest – shows that it is a sector that needs to be encouraged and supported. Both central and local government can play a big role by providing land and infrastructure, and also by implementing an enabling policy and regulatory environment which promotes small- and medium-scale urban food production.

    A long-range program is needed to maximize and sustain world food production without destroying its ecological base. Attempts to make more land available for cultivation and to increase crop yields must incorporate environmental planning as well. The most-pressing agricultural problems are soil loss because of environmental degradation, erosion, runoff, and urbanization. The large-scale use of pesticides, whose inefficient application leaves residues in food and leads to new resistant species, and irrigration projects, which lead to salination and alkalinization of groundwater and the spread of water-borne diseases, as well as other problems are dealt with best by using strategies that work with nature and natural systems.

    This paper presents the possibility of using one of the renewable energy resources in agriculture. Specifically, the paper shows the possibility of converting solar energy into electricity through photovoltaic panels. The paper includes the analysis of the energy potential of solar radiation in the AP Vojvodina (Serbia). The results of the analysis can be used for the design of photovoltaic energy systems. The amount of solar energy on the territory of the province is compared with the same data from some European countries, in order to obtain a clear picture of the possibilities of utilization of this type of renewable sources. Three examples of possible application of photovoltaic systems are presented. The first relates to the consumer who is away from the electric distribution network - photovoltaic system in island mode. The remaining two examples relate to the application of photovoltaic power sources in manufacturing plants, flowers or vegetables. Applying photovoltaic source of electrical energy to power pumps for irrigation is highlighted

    This article starts with a profile of African agricultural trade. Using the pre-release version 9.2 of the GTAP database, we then show that the results for tariff elimination on intra-African trade are promising, but these tariff barriers are not as significant as the various trade-related barriers...... outside of tariffs. Impressive results were forecast by simulating both a 50% reduction in what can be considered traditional non-tariff barriers and a modest 20% reduction in the costs associated with transit time delays at customs, terminals and internal land transportation. Gains from tariff...... elimination, non-tariff barrier reductions and time in transit cost reductions are likely to be cumulative and would generate very large gains to Africa. The policy implications are clear: while cooperation will enhance the gains, much of the benefits will result from unilateral actions and regional...

  7. Coherent Control of Nanoscale Ballistic Currents in Transition Metal Dichalcogenide ReS2.

    2015-04-28

    Transition metal dichalcogenides are predicted to outperform traditional semiconductors in ballistic devices with nanoscale channel lengths. So far, experimental studies on charge transport in transition metal dichalcogenides are limited to the diffusive regime. Here we show, using ReS2 as an example, all-optical injection, detection, and coherent control of ballistic currents. By utilizing quantum interference between one-photon and two-photon interband transition pathways, ballistic currents are injected in ReS2 thin film samples by a pair of femtosecond laser pulses. We find that the current decays on an ultrafast time scale, resulting in an electron transport of only a fraction of one nanometer. Following the relaxation of the initially injected momentum, backward motion of the electrons for about 1 ps is observed, driven by the Coulomb force from the oppositely moved holes. We also show that the injected current can be controlled by the phase of the laser pulses. These results demonstrate a new platform to study ballistic transport of nonequilibrium carriers in transition metal dichalcogenides.

  8. Anomalous Polarized Raman Scattering and Large Circular Intensity Differential in Layered Triclinic ReS2.

    The Raman tensor of a crystal is the derivative of its polarizability tensor and is dependent on the symmetries of the crystal and the Raman-active vibrational mode. The intensity of a particular mode is determined by the Raman selection rule, which involves the Raman tensor and the polarization configurations. For anisotropic two-dimensional (2D) layered crystals, polarized Raman scattering has been used to reveal the crystalline orientations. However, due to its complicated Raman tensors and optical birefringence, the polarized Raman scattering of triclinic 2D crystals has not been well studied yet. Herein, we report the anomalous polarized Raman scattering of 2D layered triclinic rhenium disulfide (ReS 2 ) and show a large circular intensity differential (CID) of Raman scattering in ReS 2 of different thicknesses. The origin of CID and the anomalous behavior in polarized Raman scattering were attributed to the appearance of nonzero off-diagonal Raman tensor elements and the phase factor owing to optical birefringence. This can provide a method to identify the vertical orientation of triclinic layered materials. These findings may help to further understand the Raman scattering process in 2D materials of low symmetry and may indicate important applications in chiral recognition by using 2D materials.

The values for the prediction equation would be obtained using OMNI-RES scale values of different loads of the bench press exercise. Sixty males ( voluntarily participated in the study and were tested using an incremental protocol on a Smith machine to determine one repetition maximum (1RM in the bench press exercise. A linear regression analysis produced a strong correlation (r = -0.94 between rating of perceived exertion (RPE and mean bar velocity (Velmean. The Pearson correlation analysis between real power output (PotReal and estimated power (PotEst showed a strong correlation coefficient of r = 0.77, significant at a level of p = 0.01. Therefore, the OMNI-RES scale can be used to predict Velmean in the bench press exercise to control the intensity of the exercise. The positive relationship between PotReal and PotEst allowed for the identification of a maximum power-training zone.

    2014-01-01

    Full Text Available The author discusses the effects of the res judicata rule as regards jurisdictional decisions of the International Court of Justice. He finds that there exists a special position of a judgment on preliminary objection in respect to both aspects of the res judicata rule - its binding force and finality. A perception of distinct relativity of a jurisdictional decision of the Court, expressing its interlocatory character pervades, in his opinion, the body of law regulating the Court's activity. Preliminary objections as such do not exhaust objections to the jurisdiction of the Court, as evidenced by non-preliminary objections to the jurisdiction of the Court giving rise to the application of the principle compétence de la compétence understood in the narrow sense. With regard to the binding force of a judgment on preliminary objections, it does not create legal obligations stricto sensu. The author finds that the relative character of jurisdictional decisions of the Court as compared with a judgment on the merits is justified on a number of grounds.

    RES Equipment Sales of Dryden, Ontario is leading the development of a battery-powered personnel utility vehicle for underground mining applications. Among the advantages of the battery-powered personnel carrier are quietness of the carrier and zero emissions, which eliminates particulates from diesel engines and reduces the need for ventilation. This article discussed the design and building of the vehicle. It was designed to accommodate up to 3 battery packs, depending on the frequency of use. Swapping batteries takes between 2 or 3 minutes. Spent batteries must be plugged in for 6 hours and rest for another 6 to 8 hours before being ready for service. The vehicle accommodates 2 or 3 people and travels at speeds of 6 to 8 miles per hour. This article also provided background information on RES Equipment Sales. The company remanufactures underground mining equipment, including load-haul-dump machines, jumbos, haul trucks and utility vehicles. In addition, the company sells and services new equipment, including Oldenburg Cannon jumbos, scalers and utility vehicles, as well as Canun International pneumatic rock drills and NPK rock breakers. 1 ref., 1 fig.

    2002-01-01

    'Full text:' Agricultural drainage systems have been identified as potential contributors of non-point source pollution. Two of the major concerns have been with nitrate-nitrogen (NO3 - -N) concentrations and bacteria levels exceeding the Maximum Acceptable Concentration in drainage water. Heightened public awareness of environmental issues has led to greater pressure to maintain the environmental quality of water systems. In an ongoing field study, three experiment sites, each with own soil properties and characteristics, are divided into drainage plots and being monitored for NO3 - -N and fecal coliforms contamination. The first site is being used to determine the impact of the rate of manure application on subsurface drainage water quality. The second site is being used to determine the difference between hog manure and inorganic fertilizer in relation to fecal coliforms and NO3-N leaching losses under a carrot rotation system. The third site examines the effect of timing of manure application on water quality, and is the only site equipped with a surface drainage system, as well as a subsurface drainage system. Each of the drains from these fields lead to heated outflow buildings to allow for year-round measurements of flow rates and water samples. Tipping buckets wired to data-loggers record the outflow from each outlet pipe on an hourly basis. Water samples, collected from the flowing drains, are analyzed for NO3 - -N concentrations using the colorimetric method, and fecal coliforms using the Most Probable Number (MPN) method. Based on this information, we will be able better positioned to assess agricultural impacts on water resources which will help towards the development on industry accepted farming practices.

    2015-12-01

    Full Text Available Agriculture is one of the most important economic activities in each country or area, as it is in close correlation with all other the other economic activities, in a whole which must be structured so as to achieve a more efficient planning and organization of the territory. The practice of a traditional agriculture, based on industrialization, affects the natural environment through emissions of pollutants, waste and deforestation which together affects biodiversity. Green Agriculture suppose to empower managers to widespread the use of fertilizers, to improve the crop rotation, to realize a more efficient water consumption, to improve the storage methods and the supply chain of products. Agricultural policies are closely interrelated with environmental policies as agricultural activities have a considerable influence on the environment. The efficiency of agricultural policies is reflected in monetary transfers between agriculture and other economic sectors, in the costs due to the reallocation of the resources between different agricultural and non-agricultural activities and in the realized gains. Currently there is a constant concern of the governments for the transition to a green agriculture, and most countries recognize the importance of achieving sustainable economic development.

    We demonstrated the fabrication of large-area ReS 2 transistors and logic gates composed of a chemical vapor deposition (CVD)-grown multilayer ReS 2 semiconductor channel and graphene electrodes. Single-layer graphene was used as the source/drain and coplanar gate electrodes. An ion gel with an ultrahigh capacitance effectively gated the ReS 2 channel at a low voltage, below 2 V, through a coplanar gate. The contact resistance of the ion gel-gated ReS 2 transistors with graphene electrodes decreased dramatically compared with the SiO 2 -devices prepared with Cr electrodes. The resulting transistors exhibited good device performances, including a maximum electron mobility of 0.9 cm 2 /(V s) and an on/off current ratio exceeding 10 4 . NMOS logic devices, such as NOT, NAND, and NOR gates, were assembled using the resulting transistors as a proof of concept demonstration of the applicability of the devices to complex logic circuits. The large-area synthesis of ReS 2 semiconductors and graphene electrodes and their applications in logic devices open up new opportunities for realizing future flexible electronics based on 2D nanomaterials.

  9. Teaching international animal agriculture.

    Science.gov (United States)

    Lukefahr, S D

    1999-11-01

    Students who major in animal science at U.S. institutions are generally exposed to a curriculum that emphasizes commercial, large-scale production of the few traditional food animals: cattle, poultry, sheep, and swine. Globally, most farmers live in lesser-developed countries under limited-resource conditions of land, feed supplies, equipment, and capital. The promotion of commercial animal production enterprises may not be appropriate for such farms because it can subject farmers to considerable economic risk. Rather, use of limited numbers of large livestock, locally adapted breeds, or smaller livestock (e.g., ducks, goats, guinea pigs, and rabbits) may be more appropriate under subsistence, integrated farming systems. In this global context, a course in international animal agriculture has been taught for 15 yr to undergraduate and graduate students. The course consists of a review of traditional and potential livestock species well suited for impoverished families on small farms and methods to implement sustainable livestock projects, including feasibility, design, implementation, monitoring, and evaluation stages. To enhance student understanding, global food issues and challenges are illustrated with case studies. A term paper is also assigned for which students choose three suitable livestock species or local breeds that would be complementary on a small crop farm (< 5 ha). Daily dietary requirements of protein and energy per family member are calculated. Itemized enterprise budgets and production tables are prepared. Early in the course, the general consensus of students was that people who are malnourished and live in poverty have low personal ambition and motivation, and that their problems should be amenable to solution by application of American technology and expertise. The course modifies such attitudes and enhances a student's critical thinking and problem-solving abilities and communication skills. Course evaluations indicated that students believed

    Full Text Available RESUMO A gestão de resíduos dos serviços de saúde (RSS constitui um grande desafio para o poder público, pois, apesar do avanço nos aspectos legislativos, ainda há grandes deficiências, especialmente relacionadas aos resíduos de medicamentos descartados inadequadamente. Este estudo teve como objetivo caracterizar o processo de descarte de drogas e resíduos dos serviços de saúde humana e veterinária em uma cidade de médio porte da Região Serrana de Santa Catarina. Foram realizadas visitas às unidades participantes, selecionadas por critérios de conveniência, contemplando unidades de saúde municipais, pet shops , clínicas veterinárias, hospital de atendimento humano, hospital de atendimento veterinário e empresas coletoras, totalizando 15 unidades participantes. A coleta de dados ocorreu de março a maio de 2014, com aplicação de questionários e roteiro de observação de campo. Os resultados evidenciaram deficiências no gerenciamento dos resíduos de medicamentos, assim como dos demais resíduos, nas etapas de segregação e armazenamento em instituições de atendimento humano e veterinário, com poucas exceções. As maiores dificuldades foram observadas nos estabelecimentos de atendimento veterinário, especialmente quanto à segregação e ao armazenamento dos resíduos contaminados, à falta de cuidado com material perfurocortante e às normas de biossegurança. A inexistência do Plano de Gerenciamento de Resíduos de Serviços de Saúde nas unidades de saúde e no hospital veterinário, assim como a falta de capacitações aos profissionais, a dissimilaridade no descarte de medicamentos entre os estabelecimentos e a falta de fiscalização por parte dos órgãos competentes foram os principais responsáveis pelo atual cenário de descarte inadequado dos resíduos na região.

    2007-01-01

    Agriculture plays an important role in the national economy of Pakistan, where most of the rapidly increasing population resides in rural areas and depends on agriculture for subsistence. Biotechnology has considerable potential for promoting the efficiency of crop improvement, food production, and poverty reduction. Use of modern biotechnology started in Pakistan since 1985. Currently, there are 29 biotech centers/institutes in the country. However, few centers have appropriate physical facilities and trained manpower to develop genetically modified (GM) crops. Most of the activities have been on rice and cotton, which are among the top 5 crops of Pakistan. Biotic (virus/bacterial/insect) and abiotic (salt) resistant and quality (male sterility) genes have already been incorporated in some crop plants. Despite acquiring capacity to produce transgenic plants, no GM crops, either produced locally or imported, have been released in the country. Pakistan is signatory to the World Trade Organization, Convention on Biological Diversity, and Cartagena protocols. Several legislations under the Agreement on Trade-Related Aspects of Intellectual Property Rights have been promulgated in the country. National Biosafety Guidelines have been promulgated in April 2005. The Plant Breeders Rights Act, Amendment in Seed Act-1976, and Geographical Indication for Goods are still passing through discussion, evaluation, and analysis phases. Meanwhile, an illegal GM crop (cotton) has already sneaked into farmer's field. Concerted and coordinated efforts are needed among various ministries for implementation of regulation and capacity building for import/export and local handling of GM crops. Pakistan could easily benefit from the experience of Asian countries, especially China and India, where conditions are similar and the agriculture sector is almost like that of Pakistan. Thus, the exchange of information and experiences is important among these nations.

    2018-03-01

    Full Text Available Machined surfaces are rough from a microscopic perspective no matter how finely they are finished. Surface roughness is an important factor to consider during production quality control. Using modern techniques, surface roughness measurements are beneficial for improving machining quality. With optical imaging of machined surfaces as input, a convolutional neural network (CNN can be utilized as an effective way to characterize hierarchical features without prior knowledge. In this paper, a novel method based on CNN is proposed for making intelligent surface roughness identifications. The technical scheme incorporates there elements: texture skew correction, image filtering, and intelligent neural network learning. Firstly, a texture skew correction algorithm, based on an improved Sobel operator and Hough transform, is applied such that surface texture directions can be adjusted. Secondly, two-dimensional (2D dual tree complex wavelet transform (DTCWT is employed to retrieve surface topology information, which is more effective for feature classifications. In addition, residual network (ResNet is utilized to ensure automatic recognition of the filtered texture features. The proposed method has verified its feasibility as well as its effectiveness in actual surface roughness estimation experiments using the material of spheroidal graphite cast iron 500-7 in an agricultural machinery manufacturing company. Testing results demonstrate the proposed method has achieved high-precision surface roughness estimation.

    Mitochondria are sub-cellular organelles that have a central role in energy production and in other metabolic pathways of all eukaryotic respiring cells. In the last few years, with more and more genomes being sequenced, a huge amount of data has been generated providing an unprecedented opportunity to use the comparative analysis approach in studies of evolution and functional genomics with the aim of shedding light on molecular mechanisms regulating mitochondrial biogenesis and metabolism. In this context, the problem of the optimal extraction of representative datasets of genomic and proteomic data assumes a crucial importance. Specialised resources for nuclear-encoded mitochondria-related proteins already exist; however, no mitochondrial database is currently available with the same features of MitoRes, which is an update of the MitoNuc database extensively modified in its structure, data sources and graphical interface. It contains data on nuclear-encoded mitochondria-related products for any metazoan species for which this type of data is available and also provides comprehensive sequence datasets (gene, transcript and protein) as well as useful tools for their extraction and export. MitoRes http://www2.ba.itb.cnr.it/MitoRes/ consolidates information from publicly external sources and automatically annotates them into a relational database. Additionally, it also clusters proteins on the basis of their sequence similarity and interconnects them with genomic data. The search engine and sequence management tools allow the query/retrieval of the database content and the extraction and export of sequences (gene, transcript, protein) and related sub-sequences (intron, exon, UTR, CDS, signal peptide and gene flanking regions) ready to be used for in silico analysis. The tool we describe here has been developed to support lab scientists and bioinformaticians alike in the characterization of molecular features and evolution of mitochondrial targeting sequences.

    Denatured radioiodinated human serum albumin (DHA) clearance studies at a dose of 1 mg/kg body wt., were carried out in 16 thalassemic children, prior to and 7-10 days following blood transfusion, to investigate changes of the effective RES blood flow which might accompany the posttransfusion spleen size diminution. A statistically significant increase (P<0.001) of the DHA plasma clearance rate was observed 7-10 days following blood transfusion denoting an increase of the blood flow to the effective RES while at the same time the spleen diminished in size. It is suggested that changes in the effective RES blood flow in these patients are directly related to changes in the intrasplenic circulatory capacity. (orig.)

    The objective of this investigation is identification the relation between the naturals resources degradation, and the Colombian agriculture productive. It's means a way to quantification the influence of a bad utilization in the water and land resources in the agricultural sector, to guide the sector in to a sustainable development. This objective is to make by an empirical exercise where we built four econometrics models (ordinary minims square) based in the Colombia's history statistic of the variables: land erosion, river sedimentation, plaguicides, Insecticides, Fungicides y Herbicides, agriculture productivity and agriculture yield. The resolute of this exercise is that an increase in the erosion area also the river sedimentation gives a decrease in the agriculture productivity. The same situation happens when it use the consumption of the insecticides and the fungicides which in the long time shows an opposite relation with the yield and productivity. At last we have that the aperture of the ninety's, bring to good changes for the agricultural productivity. So that, it concludes that the rivers and lands degradation affect in the long time the agriculture yield and productivity. The best use in the naturals resources, can help to increase the agricultural development, because it can increase the yield while it maintain for the future the possibility curve of production when it conserve the resources

The quanti cation of redistribution effects builds on the theoretical analysis by Unteutsch (2014), who shows that cooperation in RES-E support increases overall welfare but is not beneficial for all groups. In this paper, we use a dynamic investment and dispatch optimization model of the European electricity system to investigate which groups potentially benefit from cooperation and which groups would be worse off compared to a situation in which national RES-E targets are reached solely by domestic RES-E production. In the analysis, cooperation in RES-E support is implemented as a European-wide green certificate trading scheme. Main findings of the analysis include that in the European electricity system, effects of the change in the certificate price in most countries would overcompensate for the effects of the change in the wholesale electricity price. Thus, in most countries with comparatively high (low) generation costs for renewable energies, consumer rents increase (decrease) due to cooperation and producers yield lower (higher) profits. In addition, it is found that the magnitude of redistribution effects between the individual groups is quite large: In some countries, the change in consumer rents or producer profits resulting from cooperation is nearly twice as high as the overall welfare effect of cooperation in the whole European electricity system. Moreover, we find that the sign, but not always the magnitude, of redistribution effects is quite robust to different developments of interconnector extensions, the CO 2 price and RES-E investment costs.

    SERVICE ROBOTS in precision agriculture have the potential to ensure a more competitive and sustainable production, but the lack of skilled engineers within this area is limiting the industry’s ability to develop new and innovative agricultural technology products. Part of the reason...... is that engineers and scientists have little knowledge about agricultural technology, and they therefore choose to work in other domains. It is hypothesised that introducing engineering students to precision agriculture through practical work with small-scale service robots will increase their interest...... in agriculture and agricultural technology. This article presents the results of an interdisciplinary extracurricular activity for first year engineering students carried out in the Fall 2012 at the University of Southern Denmark. The case was based on practical group-work centered around an agricultural mobile...

    Occupational exposures in the agricultural industry are associated with numerous lung diseases, including chronic obstructive pulmonary disease, asthma, hypersensitivity pneumonitis, lung cancer, and interstitial lung diseases. Efforts are ongoing to ascertain contributing factors to these negative respiratory outcomes and improve monitoring of environmental factors leading to disease. In this review, recently published studies investigating the deleterious effects of occupational exposures in the agricultural industry are discussed. Occupational exposures to numerous agricultural environment aerosols, including pesticides, fungi, and bacteria are associated with impaired respiratory function and disease. Increases in certain farming practices, including mushroom and greenhouse farming, present new occupational exposure concerns. Improved detection methods may provide opportunities to better monitor safe exposure levels to known lung irritants. In the agricultural industry, occupational exposures to organic and inorganic aerosols lead to increased risk for lung disease among workers. Increased awareness of respiratory risks and improved monitoring of agricultural environments are necessary to limit pulmonary health risks to exposed populations.

    2012-03-01

    Despite the high and relatively stable overall growth of the economy, India's agriculture sector is underperforming and a vast section of the population remains undernourished. To explore the possible interplay between agricultural performance and malnutrition indicators to see whether states that perform better in agriculture record better nutritional outcomes. Correlation analysis and a simple linear regression model were used to study the relationship between agricultural performance and malnutrition among children under 5 years of age and adults from 15 to 49 years of age at 20 major states using data from the National Family Health Survey-3 for the year 2005/06 and the national accounts. Indicators of the level of agricultural performance or income have a strong and significant negative relationship with indices of undernutrition among adults and children, a result suggesting that improvement of agricultural productivity can be a powerful tool to reduce undernutrition across the vast majority of the population. In addition to agriculture, access to sanitation facilities and women's literacy were also found to be strong factors affecting malnutrition. Access to healthcare for women and child-care practices, in particular breastfeeding within 1 hour after birth, are other important determinants of malnutrition among adults and children. Malnutrition is a multidimensional problem that requires multisectoral interventions. The findings show that improving agricultural performance can have a positive impact on nutritional outcomes. However, improvements in agriculture alone cannot be effective in combating malnutrition if several other mediating factors are not in place. Interventions to improve education, health, sanitation and household infrastructure, and care and feeding practices are critical. Innovative strategies that integrate agriculture and nutrition programs stand a better chance of combating the malnutrition problem.

  20. An RES-Based Model for Risk Assessment and Prediction of Backbreak in Bench Blasting

    2013-07-01

    Most blasting operations are associated with various forms of energy loss, emerging as environmental side effects of rock blasting, such as flyrock, vibration, airblast, and backbreak. Backbreak is an adverse phenomenon in rock blasting operations, which imposes risk and increases operation expenses because of safety reduction due to the instability of walls, poor fragmentation, and uneven burden in subsequent blasts. In this paper, based on the basic concepts of a rock engineering systems (RES) approach, a new model for the prediction of backbreak and the risk associated with a blast is presented. The newly suggested model involves 16 effective parameters on backbreak due to blasting, while retaining simplicity as well. The data for 30 blasts, carried out at Sungun copper mine, western Iran, were used to predict backbreak and the level of risk corresponding to each blast by the RES-based model. The results obtained were compared with the backbreak measured for each blast, which showed that the level of risk achieved is in consistence with the backbreak measured. The maximum level of risk [vulnerability index (VI) = 60] was associated with blast No. 2, for which the corresponding average backbreak was the highest achieved (9.25 m). Also, for blasts with levels of risk under 40, the minimum average backbreaks (<4 m) were observed. Furthermore, to evaluate the model performance for backbreak prediction, the coefficient of correlation ( R 2) and root mean square error (RMSE) of the model were calculated ( R 2 = 0.8; RMSE = 1.07), indicating the good performance of the model.

  1. The Nordic welfare model providing energy transition? A political geography approach to the EU RES directive

    International Nuclear Information System (INIS)

    Westholm, Erik; Beland Lindahl, Karin

    2012-01-01

    The EU Renewable Energy Strategy (RES) Directive requires that each member state obtain 20% of its energy supply from renewable sources by 2020. If fully implemented, this implies major changes in institutions, infrastructure, land use, and natural resource flows. This study applies a political geography perspective to explore the transition to renewable energy use in the heating and cooling segment of the Swedish energy system, 1980–2010. The Nordic welfare model, which developed mainly after the Second World War, required relatively uniform, standardized local and regional authorities functioning as implementation agents for national politics. Since 1980, the welfare orientation has gradually been complemented by competition politics promoting technological change, innovation, and entrepreneurship. This combination of welfare state organization and competition politics provided the dynamics necessary for energy transition, which occurred in a semi-public sphere of actors at various geographical scales. However, our analysis, suggest that this was partly an unintended policy outcome, since it was based on a welfare model with no significant energy aims. Our case study suggests that state organization plays a significant role, and that the EU RES Directive implementation will be uneven across Europe, reflecting various welfare models with different institutional pre-requisites for energy transition. - Highlights: ► We explore the energy transition in the heating/cooling sector in Sweden 1980–2000. ► The role of the state is studied from a political geography perspective. ► The changing welfare model offered the necessary institutional framework. ► Institutional arrangements stand out as central to explain the relative success. ► The use of renewables in EU member states will continue to vary significantly.

  2. Integrated electrification solution for autonomous electrical networks on the basis of RES and energy storage configurations

    Most medium and small islands of the Aegean Archipelagos face serious infrastructure problems, strongly related with the limited electrical energy available at extremely high cost. On the other hand, the area is characterized by very high wind speeds and abundant solar energy, thus the exploitation of the available renewable energy sources (RES) may significantly contribute to the fulfillment of the local societies energy demand at minimum environmental and macroeconomic cost. However, the stochastic availability of wind energy and the variable availability of solar energy, the daily and seasonal electricity demand fluctuations, as well as the limited local electrical network capacity result in serious restrictions concerning the maximum renewable power penetration. In this context, the present paper investigates the possibility of creating a combined electricity generation facility based on the exploitation of wind or/and solar potential of an area as well as on the utilization of an appropriate energy storage configuration in order to replace the existing thermal power stations with rational investment requirements. For this purpose, the major parameters of the proposed integrated configuration are firstly calculated and its financial viability is accordingly analyzed. One of the main targets of the proposed solution is to maximize the RES exploitation of the area at a minimum electricity generation cost, while special emphasis is given in order to select the most cost-efficient energy storage device available. According to the results obtained the proposed solution is not only financially attractive but also improves the quality of the electricity offered to the local communities, substituting the expensive and heavily polluting existing thermal power stations

    Full Text Available Development of ecodegradable materials and use of them in innovative technology of sowing of seeds of grain crops in a tape isan important and actual problem of polymeric chemistry. Material is affected by programmable destruction under the influence of natural factors taking into account the biochemical processes in a plant. At the present time in literature there are no the data about polymeric materials which can operate plants biochemical processes when contacting to root system of directly in the soil. The authors developed compositions on the basis of synthetic polymer - low density polyethylene (LDPE and biodegradable polymer - a polylactide (PLA. Thermophysical properties of ecofilms change under the influence of ultra-violet radiation. Photooxidation leads to cracking of samples with the raised maintenance of PLA. Temperature of melting of PLA decreases from 165 to 152 degrees Celsius (in some compositions to 137 degrees and crystallinity degrees lower on average by 20 percent. Thus the most considerable decrease in crystallinity (about 30 percent is noted in composition with a ratio of components of 50:50 mass percent. A composition formulation affects on the speed of destructive influence of moisture and an ultraviolet. The speed advantage of these processes is characteristic for the compositions containing from 30 to 60 mass percent of PLA. The soil samples with the maintenance of PLA more than 30 mass percent will be in less time exposed to biodegradation. Composition 50:50 has the greatest loss of weight equaled 18 percent. For other samples relative loss of weight makes 5-10 percent. The test for biodestruction showed considerable change of properties of polymeric samples of PLA- LDPE depending on mix composition. It means that it is possible to select such ratio of components at which material properties would conform to requirements imposed to agricultural appointment films.

    This work studies the composability of the building blocks ofstructural CNN models (e.g., GoogleLeNet and Residual Networks) in thecontext of network pruning. We empirically validate that a networkcomposed of pre-trained building blocks (e.g. residual blocks andInception modules) not only gives a better initial setting fortraining, but also allows the training process to converge at asignificantly higher accuracy in much less time. Based on thatinsight, we propose a {\\em composability-centered} design for CNNnetwork pruning. Experiments show that this new scheme shortens theconfiguration process in CNN network pruning by up to 186.8X forResNet-50 and up to 30.2X for Inception-V3, and meanwhile, the modelsit finds that meet the accuracy requirement are significantly morecompact than those found by default schemes.

    “Increased women’s enrollment in agricultural courses” as one among the strategies when addressing gender issues in the education and training components of agricultural development projects. In this context the study was carried out to ascertain the representation of women and their academic achievement in agricultural education. The study revealed that almost equal representation was found for women in agricultural course and they were also provided better quality education in their schooling, in the form of English medium education and education in private schools. Recent trends for the past four years showed a higher percentage of enrollments of women in agricultural course than men. The growth rate was also higher for the female students. Women also showed a significantly higher percentage of academic achievement than men. These positive indicators provide sufficient signals for equality of women in agricultural course and have positive implications for development of the agricultural sector in future.

    This article describes an environmental assessment of Swedish agriculture, including upstream and downstream effects. The analysis is based on environmentally extended input-output analysis, but it is also supplemented with data from other sources. The analysis shows that direct effects by the Swedish agriculture are the most important, while indirect effects from other sources including mobile and impacts abroad are also considerable. The most important impacts from Swedish agriculture according to the analysis are eutrophication, global warming and resource use. The agricultural sector produces a large share of the Swedish emissions causing both global warming and eutrophication. In addition, current agricultural practice causes problems with loss of biodiversity. The most important actors in the sector are agriculture itself, but also all actors using fossil fuels: primarily the transport sector and the energy sector. In addition, consumers are important since they can influence the composition of agricultural production. The analysis shows the importance of including upstream and downstream effects when analysing the environmental impacts from a sector. (author)

    Reports from interdisciplinary areas including microbiology, biochemistry, animal nutrition, agricultural engineering and economics are integrated in this proceedings. The major theme of this book is environmental preservation by controlling release of undesirable greenhouse gases to realize the sustainable development of animal agriculture. Technology exists for the effective collection of methane generated from anaerobic fermentation of animal effluent and its use as a biomass energy source. Fossil fuel consumption can be reduced and there can be increased use of locally available energy sources. In addition, promoting environmentally-conscious agriculture which does not rely on the chemical fertilizer can be realized by effective use of animal manure and compost products.

    Over the coming decades, climate change is likely to pose a major challenge to agriculture; temperatures are rising, rainfall is becoming more variable and extreme weather is becoming a more common event. Researchers and policymakers agree that adapting agriculture to these impacts is a priority for ensuring future food security. Strategies to achieve that in practice tend to focus on modern science. But evidence, both old and new, suggests that the traditional knowledge and crop varieties of indigenous peoples and local communities could prove even more important in adapting agriculture to climate change.

Under its technical assistance program, IAEA assigned an expert in the agricultural applications of radioisotopes for this project. Discussions were held with regional representatives of the Food and Agriculture Organization on the best lines of research to be adopted at the laboratory in its early stages. As the most important crop in Burma is rice, a series of experiments were planned for a study of the nutrition of rice, particularly its phosphorus uptake, with special reference to comparative responses on a range of typical paddy soils. The experiments began last year and are being continued.

  11. Current experience with support schemes for RES-E in Europe. A regulatory point of view

    International Nuclear Information System (INIS)

    Lackner, Ursula

    2006-01-01

    The need to reduce the dependence of the European economy on imported primary energy and the impact of fossil fuels on the environment has encouraged countries to increase the share of renewable energy sources (RES) for electricity supply. EU Directive 2001/77/EC requires EU Member States to take appropriate steps to introduce new incentive mechanisms in order to reach the target of generating 21 % of the electricity in the EU from RES. At the same time EU Directive 2003/54/EC takes significant steps towards establishing a single market in electricity across the EU. Under this directive, European energy regulators have a number of responsibilities. These include the avoidance of discrimination and the promotion of effective competition along with an efficient functioning of the market. One of their main tasks is to ensure that European consumers pay a final electricity price that is as cost reflective as possible. The final price shall also reflect the social and the environmental costs. At the current stage it is not unlikely that the promotion of renewable energy sources will create significant barriers and distortions on the liberalized electricity market. Several issues arising from the implementation of renewable incentive schemes and policies can be identified and are analysed below; - Conflicting targets on EU-Level; - The variation in the level of incentives may be greater among Member States than is justified by the real level of technology costs, or other factors; - Unbalanced burden sharing for final consumers, due to different allocation mechanisms and designs of support schemes; -The regulation and charges for relevant items of the electricity chain, such as connection and balancing costs, vary significantly among Member States and may introduce competitive advantages. The contents of the paper is as follows: 1 Background; 2 Conflicting targets on EU-Level; 3 Different support levels; 4 Unbalanced burden sharing of final customers; 5 Allocation of

  15. Soil Erosion and Agricultural Sustainability

    Science.gov (United States)

    Montgomery, D. R.

    2009-04-01

    Data drawn from a global compilation of studies support the long articulated contention that erosion rates from conventionally plowed agricultural fields greatly exceed rates of soil production, erosion under native vegetation, and long-term geological erosion. Whereas data compiled from around the world show that soil erosion under conventional agriculture exceeds both rates of soil production and geological erosion rates by up to several orders of magnitude, similar global distributions of soil production and geological erosion rates suggest an approximate balance. Net soil erosion rates in conventionally plowed fields on the order of 1 mm/yr can erode typical hillslope soil profiles over centuries to millennia, time-scales comparable to the longevity of major civilizations. Well-documented episodes of soil loss associated with agricultural activities date back to the introduction of erosive agricultural methods in regions around the world, and stratigraphic records of accelerated anthropogenic soil erosion have been recovered from lake, fluvial, and colluvial stratigraphy, as well as truncation of soil stratigraphy (such as truncated A horizons). A broad convergence in the results from studies based on various approaches employed to study ancient soil loss and rates of downstream sedimentation implies that widespread soil loss has accompanied human agricultural intensification in examples drawn from around the world. While a broad range of factors, including climate variability and society-specific social and economic contexts — such as wars or colonial relationships — all naturally influence the longevity of human societies, the ongoing loss of topsoil inferred from studies of soil erosion rates in conventional agricultural systems has obvious long-term implications for agricultural sustainability. Consequently, modern agriculture — and therefore global society — faces a fundamental question over the upcoming centuries. Can an agricultural system

    International Nuclear Information System (INIS)

    Fischer, G.; Shah, M.; Van Velthuizen, H.

    2002-08-01

    After the introduction Chapter 2 presents details of the ecological-economic analysis based on the FAO/IIASA agro-ecological zones (AEZ) approach for evaluation of biophysical limitations and agricultural production potentials, and IIASA's Basic Linked System (BLS) for analyzing the world's food economy and trade system. The BLS is a global general equilibrium model system for analyzing agricultural policies and food system prospects in an international setting. BLS views national agricultural systems as embedded in national economies, which interact with each other through trade at the international level. The combination of AEZ and BLS provides an integrated ecological-economic framework for the assessment of the impact of climate change. We consider climate scenarios based on experiments with four General Circulation Models (GCM), and we assess the four basic socioeconomic development pathways and emission scenarios as formulated by the Intergovernmental Panel on Climate Change (IPCC) in its Third Assessment Report. Chapter 3 presents the main AEZ results of the impact of climate change on agriculture. Results comprise environmental constraints to crop agriculture; climate variability and the variability of rain-fed cereal production; changes in potential agricultural land; changes in crop-production patterns; and the impact of climate change on cereal-production potential. Chapter 4 discusses the AEZ-BLS integrated ecological-economic analysis of climate change on the world food system. This includes quantification of scale and location of hunger, international agricultural trade, prices, production, land use, etc. It assesses trends in food production, trade, and consumption, and the impact on poverty and hunger of alternative development pathways and varying levels of climate change. Chapter 5 presents the main conclusions and policy implications of this study

    2017-07-01

    Full Text Available Future power systems control will require large-scale activation of reserves at distribution level. Despite their high potential, distributed energy resources (DER used for frequency control pose challenges due to unpredictability, grid bottlenecks, etc. To deal with these issues, this study presents a novel strategy of power frequency characteristic dynamic adjustment based on the imbalance state. This way, the concerned operators become aware of the imbalance location but also a more accurate redistribution of responsibilities in terms of reserves activations is achieved. The proposed control is based on the concept of “cells” which are power systems with operating capabilities and responsibilities similar to control areas (CAs, but fostering the use of resources at all voltage levels, particularly distribution grids. Control autonomy of cells allows increased RES hosting. In this study, the power frequency characteristic of a cell is adjusted in real time by means of a fuzzy controller, which curtails part of the reserves, in order to avoid unnecessary deployment throughout a synchronous area, leading to a more localised activation and reducing losses, congestions and reserves exhaustion. Simulation tests in a four-cell reference power system prove that the controller significantly reduces the use of reserves without compromising the overall stability.

    2012-04-01

    FOR MEDICAL HUMANITARIAN ORGANIZATIONS, MAKING THEIR SOURCES OF LEGITIMACY EXPLICIT IS A USEFUL EXERCISE, IN RESPONSE TO: misperceptions, concerns over the 'humanitarian space', controversies about specific humanitarian actions, challenges about resources allocation and moral suffering among humanitarian workers. This is also a difficult exercise, where normative criteria such as international law or humanitarian principles are often misrepresented as primary sources of legitimacy. This essay first argues for a morally principled definition of humanitarian medicine, based on the selfless intention of individual humanitarian actors. Taking Médecins Sans Frontières (MSF) as a case in point, a common source of moral legitimacy for medical humanitarian organizations is their cosmopolitan appeal to distributive justice and collective responsibility. More informally, their legitimacy is grounded in the rightfulness of specific actions and choices. This implies a constant commitment to publicity and accountability. Legitimacy is also generated by tangible support from the public to individual organizations, by commitments to professional integrity, and by academic alliances to support evidence-based practice and operational research.

    Recently megalopolises have become centres of economy development worldwide. Gradual growth in energy consumption and thereafter - enormous power production and delivery to sustain metropolis’ needs entailed, rapid increase in emissions of hazardous substances in quantities, no longer tolerable for secure residence in majority of these cities. Ekaterinburg, is one of them. In order to abridge harmful pollution in Ekaterinburg and further centralize economic importance of the city, this paper proposes to implement the concept of urban sustainable development/ref. / by introducing alternative energy sources, which would progressively displace traditional fossil fuels. A number of actual cases, where the concept was successfully implemented, were studied and analysed to demonstrate how different shares of renewables can become effective substitutes to conventional energy sources in the cities strongly dependent on them: 1. Energy strategy of Pecs (Hungary); 2. International low carbon city (ILCC) project (Shenzhen, China); 3. Electric power system template of Tangshan city (China). Further, regional environmental and economic specifics of Ekaterinburg were studied to understand power consumption needs and energy generation possibilities, which led authors to conclude on the alternative energy sources feasibility, plot specific flow chart for RES implementation in Ekaterinburg’s power network and outline recommendations for future works.

    Operational research (OR) has become a hot topic at national meetings, international conferences and donor fora. The International Union Against Tuberculosis and Lung Disease (The Union) and Médecins Sans Frontières (MSF) Operational Centre Brussels strongly promote and implement OR with colleagues in low- and middle-income countries. Here we describe how the two organisations define OR, and explain the guiding principles and methodology that underpin the strategy for developing and expanding OR in those countries. We articulate The Union's and MSF's approach to supporting OR, highlighting the main synergies and differences. Then, using the Malawi National Tuberculosis Control Programme as an example, we show how OR can be embedded within tuberculosis control activities, leading to changes in policy and practice at the national level. We discuss the difficult, yet vitally important, issue of capacity building, and share our vision of a new paradigm of product-related training and performance-based OR fellowships as two ways of developing the necessary skills at country level to ensure research is actually performed. Finally, we highlight the need to consider and incorporate into practice the ethical components of OR. This is a key moment to be involved in OR. We are confident that in partnership with interested stakeholders, including the World Health Organization, we can stimulate the implementation of quality, relevant OR as an integral part of health service delivery that in turn will lead to better health for people, particularly for those living in the poorer parts of the world.

    During the Responding to HIV/AIDS: Technology Development Needs for African Smallholder Agriculture Conference in Harare, about 70 delegates participated from government and nongovernmental organizations, community-based organizations, agricultural research, and regional and international organizations. The aims of the conference were to analyze the impact of HIV/AIDS on smallholder agriculture; identify the necessary technologies, policy, and institutional responses; and propose frameworks for future activities. The conference participants noted that the onset of HIV/AIDS has changed the African rural environment in which existing policy and programs on agriculture have been operating. In view of this, recommendations on technology and development and policy to mitigate the impact of the epidemic were highlighted; namely, promote existing labor and capital saving technologies; review existing agricultural extension; develop appropriate technologies to reduce the time spent on water and fuel collection; develop income-generating activities; strengthen existing community-based initiatives; and redefine the criteria for land tenure and ownership. Moreover, collaboration between development organizations and applied research were also emphasized.

    As Earth's climate warms, agricultural producers will need to adapt. Changes, especially increases in extreme events, are already having an impact on food production, according to speakers at a 1 May session on agriculture and food security at the AGU Science Policy Conference. Christopher Field, director of the Department of Global Ecology at the Carnegie Institution for Science of Washington, D. C., pointed out the complex factors that come into play in understanding food security, including spatially varying controls and stresses, incomplete models, and the potential for threshold responses. Factors that are likely to cause problems include increasing population; increasing preference for meat, which needs more land and energy inputs to produce; climate change; and increasing use of agricultural lands for biomass energy.

    Excessive use of chemical fertilizers to increase production from available land has resulted in deterioration of soil quality. To prevent further soil deterioration, the use of methylotrophic bacteria that have the ability to colonize different habitats, including soil, sediment, water, and both epiphytes and endophytes as host plants, has been suggested for sustainable agriculture. Methylotrophic bacteria are known to play a significant role in the biogeochemical cycle in soil ecosystems, ultimately fortifying plants and sustaining agriculture. Methylotrophs also improve air quality by using volatile organic compounds such as dichloromethane, formaldehyde, methanol, and formic acid. Additionally, methylotrophs are involved in phosphorous, nitrogen, and carbon cycling and can help reduce global warming. In this review, different aspects of the interaction between methylotrophs and host plants are discussed, including the role of methylotrophs in phosphorus acquisition, nitrogen fixation, phytohormone production, iron chelation, and plant growth promotion, and co-inoculation of these bacteria as biofertilizers for viable agriculture practices.
