    Full Text Available The crop legumes such as chickpea, common bean, cowpea, peanut, pigeonpea, soybean, etc. are important source of nutrition and contribute to a significant amount of biological nitrogen fixation (>20 million tons of fixed nitrogen in agriculture. However, the production of legumes is constrained due to abiotic and biotic stresses. It is therefore imperative to understand the molecular mechanisms of plant response to different stresses and identify key candidate genes regulating tolerance which can be deployed in breeding programs. The information obtained from transcriptomics has facilitated the identification of candidate genes for the given trait of interest and utilizing them in crop breeding programs to improve stress tolerance. However, the mechanisms of stress tolerance are complex due to the influence of multi-genes and post-transcriptional regulations. Furthermore, stress conditions greatly affect gene expression which in turn causes modifications in the composition of plant proteomes and metabolomes. Therefore, functional genomics involving various proteomics and metabolomics approaches have been obligatory for understanding plant stress tolerance. These approaches have also been found useful to unravel different pathways related to plant and seed development as well as symbiosis. Proteome and metabolome profiling using high-throughput based systems have been extensively applied in the model legume species Medicago truncatula and Lotus japonicus, as well as in the model crop legume, soybean, to examine stress signalling pathways, cellular and developmental processes and nodule symbiosis. Moreover, the availability of protein reference maps as well as proteomics and metabolomics databases greatly support research and understanding of various biological processes in legumes. Protein-protein interaction techniques, particularly the yeast two-hybrid system have been advantageous for studying symbiosis and stress signalling in legumes. In

    Challenged by population increase, climatic change, and soil deterioration, crop improvement is always a priority in securing food supplies. Although the production of grain legumes is in general lower than that of cereals, the nutritional value of grain legumes make them important components of food security. Nevertheless, limited by severe genetic bottlenecks during domestication and human selection, grain legumes, like other crops, have suffered from a loss of genetic diversity which is essential for providing genetic materials for crop improvement programs. Illustrated by whole-genome-sequencing, wild relatives of crops adapted to various environments were shown to maintain high genetic diversity. In this review, we focused on nine important grain legumes (soybean, peanut, pea, chickpea, common bean, lentil, cowpea, lupin, and pigeonpea) to discuss the potential uses of their wild relatives as genetic resources for crop breeding and improvement, and summarized the various genetic/genomic approaches adopted for these purposes.

    More than one hundred articles published by Egyptian research workers dealing with the improvement of some seed-legumes through radiation, radioisotopes, chemical mutagens and induced mutations are briefly summarized and discussed from the point of view of a mutation breeder working in this field since 1961. Articles on faba bean (Vicia faba L.), soybean (Glycine Max L.), lentils (Lens culinaris), chick-pea (Cicer arietinum L.), lupin (Lupinus termis), peas=pea (Pisum sativum L.), cowpea (Vigna sinensis, savi), and fenugreek-helba (Trigonella foenum gracum L.) are reviewed. A very few number of promising mutations have been induced. However, none of them are utilized neither in conventional breeding programs nor as cultivars. This may be due to the lack of central plans and organization between efforts or research work being carried in various institutions. Joint plants and cooperation between research institutions, not only in Egypt but also among the Arab countries, are required in this field which may help in closing the wide gab between production and consumption os seed legumes.

  5. Legume root symbioses: Natural history and prospects for improvement

    2011-01-01

    Full Text Available Legumes develop different mutually beneficial microbial-root symbioses such as arbuscular mysorrhiza (AM, rhizobium-legume symbiosis (RLS and epiphytic or endophytic associations with plant growth-promoting bacteria (PGPB which are distinguished in level of integration of the partners. Evidences of the role of AM as ancestral form of symbiosis which might be a source of the legume pre-adaptation to form some RLS are demonstrated. The RLS is supposed to evolve for a few times in ancient legumes in parallel ways based on the universal organization and regulatory mechanisms of the plant genetic material. Associations of plant roots with PGPB probably are the vestige of the early stages of evolution in morphologically differentiated RLS. Also, it is quite possible that 'first' rhizobia have originated from bacterial endosymbionts of AM fungi; then AM fungi might operate as effective vectors for introducing bacteria into the plants. Thus, the legume root symbioses may be considered as a single 'evolutionary plant-microbial continuum'. The acquired knowledge about evolution of plantmicrobe symbioses would contribute to the creation of new commercial varieties of plants with the use of both bio-engineered methods and traditional plant breeding. An original conception of legume breeding to improve their symbiotic effectiveness is proposed.

    In assessing the nutritional limitation of legume proteins it is essential to consider both sulphur amino acids, methionine and cysteine. The possibility of using total seed sulphur as a criteria for screening for improved protein quality is discussed. In some species when relatively large amounts of S-methyl-cysteine are present, total sulphur determinations would be invalid unless that amino acid were extracted with ethanol before the sulphur determination. Methods for sulphur determination are discussed and evaluated. (author)

    Full Text Available The low rates of estimated genetic gains in forage legumes breeding have emphasized the need for new breeding methods that would increase efficiency in forage selection and provide reliable improvement. Information on application of molecular methodologies and tools for the enhancement of the current empirical phenotype-based selection moved us toward implementation of DNA markers to our breeding activities. Firstly, attention was given to identification of genetic variability within the forage species involved in program and comparison of conventional and molecular marker efficiency in variability evaluation. RAPDs were used (i to estimate availability of alfalfa (Medicago sativa L. and Medicago falcata L. genetic variation and (ii to identify changes of red clover (Trifolium pratense L. variability after natural selection. SSRs were applied to evaluate diversity within and among field pea (Pisum sativum L. var. arvense and sativum groups/varieties. A total of 90 (alfalfa or 92 (red clover polymorphic bands was found by RAPDs. Total number of SSR alleles recorded was 118. The average Roger's distance per species/genus estimated was 0.29 (red clover, 0.33 (alfalfa and 0.51 (field pea. 2D PCo analysis of each species/genus separated materials into respective groups. A high degree of genetic variation within populations/varieties of each investigated species was found by AMOVA. The correspondence between pairs of matrices based on the morphological and molecular data was significant (p=0.95 only for red clover. RAPD and SSR data have given valuable information on genetic structure of materials and provided a description that determines heterogeneity. Further studies will be focused on identifying quantitative trait loci and marker assisted selection.

    International Nuclear Information System (INIS)

    1979-01-01

    Based upon the recommendations of a panel of experts in 1968, the Joint FAO/IAEA Division of Atomic Energy in Food and Agriculture established an international programme to improve the protein content and quality in seed crops of importance to developing countries. Reports of previous meetings held under this programme have been published by the IAEA. The meeting on Seed Protein Improvement in Cereals and Grain Legumes, held in September 1978, marked the formal end of the FAO/IAEA/GSF Co-ordinated Research Programme on Seed Protein Improvement. It reviewed the progress achieved. Volume I covers 27 papers. Following a review of the world protein and nutritional situation, the contributions are grouped under the main headings of the need for and use of variability in protein characteristics; genetics, biochemistry and physiology of seed storage proteins; analytical and nutritional techniques; and coordinated research programmes under a joint FAO/IAEA/GSF programme on grain protein improvement. Individual papers of direct relevance are cited as separate entries in INIS

    1978-01-01

    Full text: This Symposium organized in co-operation with the Gesellschaft fur Strahlen- und Umweltforschung mbH (GSF), Neuherberg near Munich, Federal Republic of Germany, was the culmination of the eight year FAO/IAEA/GSF Co-ordinated Research Programme to Improve Protein Content and Quality of Crops by Nuclear Techniques The co-ordinated research programme has stimulated plant breeding in developing countries, assisted in the development of techniques for the identification and evaluation of nutritionally improved mutants and encouraged basic research on seed storage proteins. The Symposium comprised 90 scientific presentations plus equipment displays. Sixty-one scientific papers were orally presented and discussed in eight sessions. An additional 29 scientific contributions were presented as posters and were on display throughout the Symposium. One afternoon of the Symposium was devoted to examination and individual discussion of the poster displays. It was especially notable that this method of presentation and discussion of scientific results was very favourably received. Five items of scientific equipment demonstrated analytical systems in use for protein or amino acid assay in plant breeding programmes. The Symposium clearly demonstrated the reality of nutritional deficiencies in poor countries and outlined plant breeding strategies for overcoming these. Progress was reported in improving the nutritional quality of cereals (wheat, maize, rice, barley, sorghum, millet, triticale, oats), legumes (beans, peas, soybeans, field beans, chick peas, lentils, pigeon peas, cowpeas, grams, peanuts) and some other crops (cotton, buckwheat). Notable results have been achieved, but much of the work has been in progress less than 10 years, which is too short a time for the development, testing and release of commercial varieties. Chemical and nutritional assay methods, including some promising new methods were reviewed and assessed. Rapid developments in knowledge of the

    1979-01-01

    Plant breeders, molecular biologists, analytical chemists and nutritionists report on progress and achievements to date. High-lysine genotypes of maize, barley and sorghum have been produced. One high-protein variety of wheat is reported available for commercial use. Grain legumes already have high seed protein content but, compared to cereals, less of the total biological yield is available as seed, and intensive efforts are being made to produce genotypes with higher seed yield. Genetic variability is available from world germplasm collections and from induced-mutation programmes. In the basic sciences considerable advances are reported. Putative structural genes determining protein quality and quantity have been located on various chromosomes. In vitro synthesis of legume and cereal storage proteins and the isolation of some mRNA and the preparation and cloning of cDNA have been reported. Uptake and incorporation of N into amino acids, their synthesis into proteins, and interaction between protein and carbohydrate biosynthesis during seed development are discussed. Future prospects are considered including potential selection at the cellular rather than the whole plant level. In only a minority of the 64 papers is the use of nuclear techniques indicated specifically enough to justify individual entries in INIS

    1975-01-01

    The potential for use of gamma radiation processing to improve texture, hydration and cooking quality of pulses, particularly red gram, has been examined. The textural changes in irradiated pulses in terms of softening is measured by a texturometer, Radiation (1 Mrad) processing of pulses resulted in reduction of cooking time varying from 8 to 39%, red gram showing the maximum reduction. Initial higher hydration rate on soaking and cooking, stabilized on prolonged cooking and resulted in better and uniform texture of irradiated red gram. In the uncooked, irradiated (1 Mrad) sample, destruction of riboflavin was negligible, whereas thiamine and niacin showed about 7% loss. However, the vitamins were retained better in the samples irradiated and then cooked, compared to the corresponding control ones. (F.J.)

    Full Text Available A pot experiment in green house was done to study the effect of the dosage and speciesof perennial legume green manures to the physiological traits, growth and yield of organic lowland rice (Oryza sativaL., and to obtain the optimal dosage as well.  The research was arranged in a factorial randomized block design consistedof two factors with three replications.The first factor was the species of perennial legume thatconsisted of threespecies: Turi (Sesbaniagrandiflora, Glirisidia (Gliricidiasepium, and Lamtoro (Leucaenaleucocephala and cow manure as control treatment. The second factor was the dosage of green manure thatconsisted of four levels: 5, 10, 20 and 40 t/ha.  The results showed that application ofperennial legumesinto the soil significantly improved the growth and yield of rice.  The application of  20 t Glirisidia leaves/haproduced the highest grain yield, followed by 20 t Lamtoro leaves/ha and 20 t Turi leaves/ha.  The optimal dosages of S. grandiflora, G. sepium and L. leucochepala leaves that could yield 58.03 g/hill (equivalent to14.51 t/ha, 53.67 g/hill (equivalent to 13.42 t/ha, and 49.67 g/hill (equivalent to 12.42 t/ha were 28.05, 25.46 and 26.41 t/ha, respectively.

  3. Food Legumes and Rising Temperatures: Effects, Adaptive Functional Mechanisms Specific to Reproductive Growth Stage and Strategies to Improve Heat Tolerance

    Directory of Open Access Journals (Sweden)

    Kumari Sita

    2017-10-01

    Full Text Available Ambient temperatures are predicted to rise in the future owing to several reasons associated with global climate changes. These temperature increases can result in heat stress- a severe threat to crop production in most countries. Legumes are well-known for their impact on agricultural sustainability as well as their nutritional and health benefits. Heat stress imposes challenges for legume crops and has deleterious effects on the morphology, physiology, and reproductive growth of plants. High-temperature stress at the time of the reproductive stage is becoming a severe limitation for production of grain legumes as their cultivation expands to warmer environments and temperature variability increases due to climate change. The reproductive period is vital in the life cycle of all plants and is susceptible to high-temperature stress as various metabolic processes are adversely impacted during this phase, which reduces crop yield. Food legumes exposed to high-temperature stress during reproduction show flower abortion, pollen and ovule infertility, impaired fertilization, and reduced seed filling, leading to smaller seeds and poor yields. Through various breeding techniques, heat tolerance in major legumes can be enhanced to improve performance in the field. Omics approaches unravel different mechanisms underlying thermotolerance, which is imperative to understand the processes of molecular responses toward high-temperature stress.

    Excess copper (Cu) in soils has deleterious effects on plant growth and can pose a risk to human health. In the last decade, legume-rhizobium symbioses became attractive biotechnological tools for metal phytostabilization. For this technique being useful, metal-tolerant symbionts are required, which can be generated through genetic manipulation.In this work, a double symbiotic system was engineered for Cu phytostabilization: On the one hand, composite Medicago truncatula plants expressing the metallothionein gene mt4a from Arabidopsis thaliana in roots were obtained to improve plant Cu tolerance. On the other hand, a genetically modified Ensifer medicae strain, expressing copper resistance genes copAB from Pseudomonas fluorescens driven by a nodulation promoter, nifHp, was used for plant inoculation. Our results indicated that expression of mt4a in composite plants ameliorated plant growth and nodulation and enhanced Cu tolerance. Lower levels of ROS-scavenging enzymes and of thiobarbituric acid reactive substances (TBARS), such as malondialdehyde (a marker of lipid peroxidation), suggested reduced oxidative stress. Furthermore, inoculation with the genetically modified Ensifer further improved root Cu accumulation without altering metal loading to shoots, leading to diminished values of metal translocation from roots to shoots. The double modified partnership is proposed as a suitable tool for Cu rhizo-phytostabilization.

  5. Potential use of phytocystatins in crop improvement, with a particular focus on legumes.

    Phytocystatins are a well-characterized class of naturally occurring protease inhibitors that function by preventing the catalysis of papain-like cysteine proteases. The action of cystatins in biotic stress resistance has been studied intensively, but relatively little is known about their functions in plant growth and defence responses to abiotic stresses, such as drought. Extreme weather events, such as drought and flooding, will have negative impacts on the yields of crop plants, particularly grain legumes. The concepts that changes in cellular protein content and composition are required for acclimation to different abiotic stresses, and that these adjustments are achieved through regulation of proteolysis, are widely accepted. However, the nature and regulation of the protein turnover machinery that underpins essential stress-induced cellular restructuring remain poorly characterized. Cysteine proteases are intrinsic to the genetic programmes that underpin plant development and senescence, but their functions in stress-induced senescence are not well defined. Transgenic plants including soybean that have been engineered to constitutively express phytocystatins show enhanced tolerance to a range of different abiotic stresses including drought, suggesting that manipulation of cysteine protease activities by altered phytocystatin expression in crop plants might be used to improve resilience and quality in the face of climate change. © The Author 2015.

  6. Characterizing the Suitability of Selected Indigenous Soil Improving Legumes in a Humid Tropical Environment Using Shoot and Root Attributes

    Directory of Open Access Journals (Sweden)

    Anikwe, MAN.

    2003-01-01

    Full Text Available We studied the biomass accumulation, root length, nodulation, and chemical composition of roots and shoot of ten indigenous soil improving legumes in a humid tropical ecosystem with the view to selecting species for soil improvement programmes. Two cultivars of Vigna unguiculata, and one each of Glycine max, Arachis hypogaea, Crotararia ochroleuca, Cajanus cajan, Pueraria phaseoloides, Lablab purpureus, Mucuna pruriens and Vigna subterranea as treatments were planted in 20 kg pots containing soil from an Oxic paleustalf in Nigeria. The pots were arranged in randomized complete block layout with three replications in a greenhouse at IITA Ibadan, Nigeria. Results from the work show that M. pruriens and C. cajan produced the highest quantity of biomass. Root elongation was highest in M. pruriens whereas A. hypogaea produced the most root nodules with native rhizobia. The highest quantity of nodule dry weight was produced by A. hypogaea and P. phaseoloides whereas most of the legumes except G. max and P. phaseoloides had high and statistically comparable N content of between 2.36 and 3.34 mg.kg-1 N. The results show that the legumes have different root and shoot characteristics, which should be taken into consideration when selecting species for soil improvement programmes.

    This study was conducted to explore the changes in soil microbial populations, enzyme activity, and tuber yield under the rotation sequences of Potato–Common vetch (P–C), Potato–Black medic (P–B) and Potato–Longdong alfalfa (P–L) in a semi–arid area of China. The study also determined the effects of continuous potato cropping (without legumes) on the above mentioned soil properties and yield. The number of bacteria increased significantly (p continuous cropping soils, respectively compared to P–C rotation. The highest fungi/bacteria ratio was found in P–C (0.218), followed by P–L (0.184) and then P–B (0.137) rotation over the different cropping years. In the continuous potato cropping soils, the greatest fungi/bacteria ratio was recorded in the 4–year (0.4067) and 7–year (0.4238) cropping soils and these were significantly higher than 1–year (0.3041), 2–year (0.2545) and 3–year (0.3030) cropping soils. Generally, actinomycetes numbers followed the trend P–L>P–C>P–B. The P–L rotation increased aerobic azotobacters in 2–year (by 26% and 18%) and 4–year (40% and 21%) continuous cropping soils compared to P–C and P–B rotation, respectively. Generally, the highest urease and alkaline phosphate activity, respectively, were observed in P–C (55.77 mg g–1) and (27.71 mg g–1), followed by P–B (50.72 mg mg–1) and (25.64 mg g–1) and then P–L (41.61 mg g–1) and (23.26 mg g–1) rotation. Soil urease, alkaline phosphatase and hydrogen peroxidase activities decreased with increasing years of continuous potato cropping. On average, the P–B rotation significantly increased (p improve soil biology environment, alleviate continuous cropping obstacle and increase potato tuber yield in semi–arid region. PMID:28463981

  9. Intercropping frost-sensitive legume crops with winter oilseed rape reduces weed competition, insect damage, and improves nitrogen use efficiency

    2015-05-01

    Full Text Available Mixing plant species in agroecosystems is highlighted as an agroecological solution to reduce pesticides and fertilizers while maintaining profitability. In the French context, intercropping frost-sensitive legume crops with winter oilseed rape is potentially interesting and began to be implemented by farmers. In this study we aimed at measuring the services and disservices of this intercrop with three different legume mixtures, in terms of growth and yield for rapeseed, ground cover of weeds in autumn and damage caused by rape winter stem weevil. The experiment was carried out at four sites from 2011 to 2014. We showed higher total aerial dry weights and total aerial nitrogen contents in the intercrops compared to sole winter oilseed rape in November. The companion plants contributed to the control of weeds and the mitigation of rape winter stem weevil damage, notably through the increase in the total aerial weight. In spring, after destruction of the companion plants, the intercrops had partially compensated a reduction in the N fertilization rate (–30 kg per hectare in terms of aerial nitrogen content in rapeseed, with no consequences on the yield which was maintained or even increased. There were probably other interactions such as an improvement in rapeseed root exploration. The consequences were an increase in the nitrogen use efficiency in intercrops. The intercrop with faba bean and lentil showed the best results in terms of autumn growth, weed control, reduction in rape winter stem weevil damage, and rapeseed N content in spring and yield. Intercropping frost-sensitive legume crops with winter oilseed rape is thus a promising way to reconcile yield and reduction in pesticides and fertilizer use and perhaps to benefit more widely to the cropping system.

  10. Heart of endosymbioses: transcriptomics reveals a conserved genetic program among arbuscular mycorrhizal, actinorhizal and legume-rhizobial symbioses.

    Directory of Open Access Journals (Sweden)

    Alexandre Tromas

    Full Text Available To improve their nutrition, most plants associate with soil microorganisms, particularly fungi, to form mycorrhizae. A few lineages, including actinorhizal plants and legumes are also able to interact with nitrogen-fixing bacteria hosted intracellularly inside root nodules. Fossil and molecular data suggest that the molecular mechanisms involved in these root nodule symbioses (RNS have been partially recycled from more ancient and widespread arbuscular mycorrhizal (AM symbiosis. We used a comparative transcriptomics approach to identify genes involved in establishing these 3 endosymbioses and their functioning. We analysed global changes in gene expression in AM in the actinorhizal tree C. glauca. A comparison with genes induced in AM in Medicago truncatula and Oryza sativa revealed a common set of genes induced in AM. A comparison with genes induced in nitrogen-fixing nodules of C. glauca and M. truncatula also made it possible to define a common set of genes induced in these three endosymbioses. The existence of this core set of genes is in accordance with the proposed recycling of ancient AM genes for new functions related to nodulation in legumes and actinorhizal plants.

    The Containment Performance Improvement (CPI) program has been one of the main elements in the US Nuclear Regulatory Commission's (NRC's) integrated approach to closure of severe accident issues for US nuclear power plants. During the course of the program, results from various probabilistic risk assessment (PRA) studies and from severe accident research programs for the five US containment types have been examined to identify significant containment challenges and to evaluate potential improvements. The five containment types considered are: the boiling water reactor (BMR) Mark I containment, the BWR Mark II containment, the BWR Mark III containment, the pressurized water reactor (PWR) ice condenser containment, and the PWR dry containments (including both subatmospheric and large subtypes). The focus of the CPI program has been containment performance and accident mitigation, however, insights are also being obtained in the areas of accident prevention and accident management

    Mutation breeding was studied on barley (variety Athenais) and Italian drurum wheat (variety Capeiti). Gamma radiation and fast neutrons were used. The intention is to use high protein lines of barley and wheat in crosses with the high-yielding varieties grown in Cyprus, in order to develop new varieties with high seed protein, without reducing grain yield. The work on forage legumes was limited to the screening of varieties of forage vetches and medics, as part of the programme on improving dryland forage crops. Tables indicate the relative performance of M 6 -lines of Attiki barley (1977-79) and of M 4 Athenais barley (1978-79). A list of 8 publications by the author, some of them jointly with A. della, is given, relating to the project

    During fuel cycle 1 at River Bend station, considerable effort was expended to reduce corrective maintenance work orders (MWOs) to <1,000. This was done by complementing the plant staff with costly contract personnel. Coming out of the first refueling outage, most contract personnel were released. The change in MWO backlog started a steady rise. It became readily apparent that to avoid costly contract staff time, a maintenance improvement program (MIP) was necessary. The MIP Was primarily directed at two areas: crew efficiency improvements and improved preplanned MWO packages. The overall effect of the MIP was to achieve significant productivity improvements with reduced operation and maintenance cost by providing frequent accountability to all levels of maintenance supervision. The MIP also produced a feeling of pride among the maintenance department employees that had not really existed before. This was the best benefit of all

    1998-07-01

    The Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture initiated a Co-ordinated Research Project on The Use of Isotopes in Studies to Improve Yield and N 2 Fixation of Grain Legumes with the Aim of Increasing Food Production and Saving N-fertilizer in the Tropics and Sub-Tropics of Asia that was operational from 1990 to 1995. This Project was underpinned by extensive experience in the use of 15 N-labelled fertilizer in quantifying N 2 fixation by food and pasture legumes; the isotope-dilution technique, recognized as the most accurate mode of quantifying fixation, was developed at the IAEA and has been used profitably for over 20 years in co-ordinated research projects that were focused on aspects relevant to the sustainability of agriculture in developing countries in which food security is most under threat. This effort to improve N 2 fixation by food legumes in Asia, and in so doing to increase productivity of cereal-based farming systems as a whole, was timely in terms of regional needs. It was complemented by an overlapping Co-ordinated Research Project entitled ''The Use of Nuclear and Related Techniques in Management of Nitrogen Fixation by trees for Enhancing Soil Fertility and Soil Conservation in Fragile Tropical Soils''. The project involved scientists from Australia, Bangladesh, China, India, Malaysia, Pakistan the Philippines, Sri Lanka, Thailand and Viet Nam

    2016-08-02

    The United Nations declared 2016 as the International Year of Pulses (grain legumes) under the banner 'nutritious seeds for a sustainable future'. A second green revolution is required to ensure food and nutritional security in the face of global climate change. Grain legumes provide an unparalleled solution to this problem because of their inherent capacity for symbiotic atmospheric nitrogen fixation, which provides economically sustainable advantages for farming. In addition, a legume-rich diet has health benefits for humans and livestock alike. However, grain legumes form only a minor part of most current human diets, and legume crops are greatly under-used. Food security and soil fertility could be significantly improved by greater grain legume usage and increased improvement of a range of grain legumes. The current lack of coordinated focus on grain legumes has compromised human health, nutritional security and sustainable food production.

    Full Text Available The objective of this research is to determine a suitable mixture of annual feed legumes and barley as a winter crop under dry-land conditions. Seeds of Hungarian vetch (cv. 2670, smooth vetch (cv. Maragheh, and local varieties of grass pea and field pea were mixed with barley (cv. Abidar in a 1:1 ratio and were tested, along with related monoculture. All legumes in the mixture survived winter while legumes alone, except Hungarian vetch, did not survive in the cold areas. The maximum fresh and dry forage yields (56 and 15 ton ha-1 respectively were obtained from a mixture of smooth vetch and barley in provinces with mild winter and more than 400 mm of rainfall. The mixture of barley and smooth vetch resulted in the highest mean crude protein content (17%. Autumn seeding of smooth vetch and barley in a 1:1 ratio produced more than 2 ton ha-1 of dry biomass with good quality in all studied areas and thus could serve as an alternative cropping system after wheat/barley in cold and semi-cold dry land.

  18. How legumes recognize rhizobia.

    Via, Virginia Dalla; Zanetti, María Eugenia; Blanco, Flavio

    2016-01-01

    Legume plants have developed the capacity to establish symbiotic interactions with soil bacteria (known as rhizobia) that can convert N2 to molecular forms that are incorporated into the plant metabolism. The first step of this relationship is the recognition of bacteria by the plant, which allows to distinguish potentially harmful species from symbiotic partners. The main molecular determinant of this symbiotic interaction is the Nod Factor, a diffusible lipochitooligosaccharide molecule produced by rhizobia and perceived by LysM receptor kinases; however, other important molecules involved in the specific recognition have emerged over the years. Secreted exopolysaccharides and the lipopolysaccharides present in the bacterial cell wall have been proposed to act as signaling molecules, triggering the expression of specific genes related to the symbiotic process. In this review we will briefly discuss how transcriptomic analysis are helping to understand how multiple signaling pathways, triggered by the perception of different molecules produced by rhizobia, control the genetic programs of root nodule organogenesis and bacterial infection. This knowledge can help to understand how legumes have evolved to recognize and establish complex ecological relationships with particular species and strains of rhizobia, adjusting gene expression in response to identity determinants of bacteria.

    1983-07-01

    A modest Tevatron improvement program is suggested which would provide a storage ring for dedicated use as a p anti p collider at 2 TeV (cm) and as an ep collider at 0.2 TeV (cm). It could also serve as a useful test facility for some of the new developments necessary for an economical SSC. Because use could be made of utilities and facilities that are already installed as part of the tevatron, the cost of the p anti p option might be about 100 million dollars (not including the interaction halls or detectors). The additional cost of a 10 x 1000 GeV' ep option might be about 70 million dollars. The experimental facilities at B and D of the Tevatron might be extended for use with the new collider. As the technology of superconducting magnets develops, the cm energy of the p anti p and the ep colliders might be doubled. The intention is either to double the capability of TeV I and TeV II, or to extend the capability by addition of an ep facility. Alternatively, by adding another proton ring, a high luminosity pp facility might also result

    Legumes are the major sources of food and fodder with strong commercial relevance, and are essential components of agricultural ecosystems owing to their ability to carry out endosymbiotic nitrogen fixation. In recent years, legumes have become one of the major choices of plant research. The legume proteomics is currently represented by more than 100 reference maps and an equal number of stress-responsive proteomes. Among the 48 legumes in the protein databases, most proteomic studies have been accomplished in two model legumes, soybean, and barrel medic. This review highlights recent contributions in the field of legume proteomics to comprehend the defence and regulatory mechanisms during development and adaptation to climatic changes. Here, we attempted to provide a concise overview of the progress in legume proteomics and discuss future developments in three broad perspectives: (i) proteome of organs/tissues; (ii) subcellular compartments; and (iii) spatiotemporal changes in response to stress. Such data mining may aid in discovering potential biomarkers for plant growth, in general, apart from essential components involved in stress tolerance. The prospect of integrating proteome data with genome information from legumes will provide exciting opportunities for plant biologists to achieve long-term goals of crop improvement and sustainable agriculture. © 2015 WILEY-VCH Verlag GmbH & Co.

    Full Text Available Primary receptacles improve profitability legumes are limiting demonstrations and acts of plant diseases and pests. Pathogens are 25-50% lower yield of soybean, chickpea, beans, peas. Pests focally up to 87% of viable seeds sown reduce the number of plants per 1 ha. Only effective protection against disease and estimates of crop production can increase the average profitability of legume crops by 15-30%. Livestock is very important, but in the Southern Urals requires real support for its production with a positive balance (in the calculations with a deviation of 5%. The most important resource in our opinion may be a reduction in price of fodder. Thus, legumes are sought for animal protein. Soybeans, chickpeas, beans, peas universal culture and the possibility of their use in the food balance for a healthy diet of ordinary people engaged in recreational and other sports niche expands further improve the profitability of their production. Regulation of the balance of the distribution of food and feed produced grain legumes allows fine regulation of the cost of fodder for a particular type of livestock activities. Phytosanitary capabilities , the balance of influence of legumes on arable land, also requires a fine regulation of these processes. Obtaining long-term public support for this production is unlikely in the WTO because actual search for ways to improve the profitability of production of agricultural technologies. In our view, a comprehensive approach taking into account the capacity of local markets for crop production. Such activity can act as a guaranteed quality of agro-technology and animal products from local resources specific zonal conditions of production.

  3. Legume bioactive compounds: influence of rhizobial inoculation

    2017-04-01

    Full Text Available Legumes consumption has been recognized as beneficial for human health, due to their content in proteins, fiber, minerals and vitamins, and their cultivation as beneficial for sustainable agriculture due to their ability to fix atmospheric nitrogen in symbiosis with soil bacteria known as rhizobia. The inoculation with these baceria induces metabolic changes in the plant, from which the more studied to date are the increases in the nitrogen and protein contents, and has been exploited in agriculture to improve the crop yield of several legumes. Nevertheless, legumes also contain several bioactive compounds such as polysaccharides, bioactive peptides, isoflavones and other phenolic compounds, carotenoids, tocopherols and fatty acids, which makes them functional foods included into the nutraceutical products. Therefore, the study of the effect of the rhizobial inoculation in the legume bioactive compounds content is gaining interest in the last decade. Several works reported that the inoculation of different genera and species of rhizobia in several grain legumes, such as soybean, cowpea, chickpea, faba bean or peanut, produced increases in the antioxidant potential and in the content of some bioactive compounds, such as phenolics, flavonoids, organic acids, proteins and fatty acids. Therefore, the rhizobial inoculation is a good tool to enhance the yield and quality of legumes and further studies on this field will allow us to have plant probiotic bacteria that promote the plant growth of legumes improving their functionality.

    Legumes play a vital role in ensuring global nutritional food security and improving soil quality through nitrogen fixation. Accelerated higher genetic gains is required to meet the demand of ever increasing global population. In recent years, speedy developments have been witnessed in legume genomics due to advancements in next-generation sequencing (NGS) and high-throughput genotyping technologies. Reference genome sequences for many legume crops have been reported in the last 5 years. The availability of the draft genome sequences and re-sequencing of elite genotypes for several important legume crops have made it possible to identify structural variations at large scale. Availability of large-scale genomic resources and low-cost and high-throughput genotyping technologies are enhancing the efficiency and resolution of genetic mapping and marker-trait association studies. Most importantly, deployment of molecular breeding approaches has resulted in development of improved lines in some legume crops such as chickpea and groundnut. In order to support genomics-driven crop improvement at a fast pace, the deployment of breeder-friendly genomics and decision support tools seems appear to be critical in breeding programs in developing countries. This review provides an overview of emerging genomics and informatics tools/approaches that will be the key driving force for accelerating genomics-assisted breeding and ultimately ensuring nutritional and food security in developing countries.

    Medicago truncatula has been developed into a model legume. Its close relative alfalfa (Medicago sativa) is the most widely grown forage legume crop in the United States. By screening a large population of M. truncatula mutants tagged with the transposable element of tobacco (Nicotiana tabacum) cell type1 (Tnt1), we identified a mutant line (NF2089) that maintained green leaves and showed green anthers, central carpels, mature pods, and seeds during senescence. Genetic and molecular analyses revealed that the mutation was caused by Tnt1 insertion in a STAY-GREEN (MtSGR) gene. Transcript profiling analysis of the mutant showed that loss of the MtSGR function affected the expression of a large number of genes involved in different biological processes. Further analyses revealed that SGR is implicated in nodule development and senescence. MtSGR expression was detected across all nodule developmental zones and was higher in the senescence zone. The number of young nodules on the mutant roots was higher than in the wild type. Expression levels of several nodule senescence markers were reduced in the sgr mutant. Based on the MtSGR sequence, an alfalfa SGR gene (MsSGR) was cloned, and transgenic alfalfa lines were produced by RNA interference. Silencing of MsSGR led to the production of stay-green transgenic alfalfa. This beneficial trait offers the opportunity to produce premium alfalfa hay with a more greenish appearance. In addition, most of the transgenic alfalfa lines retained more than 50% of chlorophylls during senescence and had increased crude protein content. This study illustrates the effective use of knowledge gained from a model system for the genetic improvement of an important commercial crop.

    2013-01-01

    The aim of this study was to investigate whether the use of sainfoin-based condensed tannins (CT) enhances feed value when given with tannin-free legumes (lucerne) to sheep. The experiments were conducted with fresh sainfoin and lucerne harvested at two stages (vegetative stage as compared with early flowering) in the first growth cycle. Fresh sainfoin and lucerne forages were combined in ratios of 100 : 0, 75 : 25, 25 : 75 and 0 : 100 (denoted S100, S75, S25 and S0, respectively). Voluntary intake, organic matter digestibility (OMD) and nitrogen (N) retention were measured in sheep fed the different sainfoin and lucerne mixtures. Loss of dry matter (DM) and N from polyester bags suspended in the rumen, abomasum and small intestine (SI) was also measured using rumen-fistulated sheep and intestinally fistulated sheep. The CT content in sainfoin (S100) decreased with increasing percentage of lucerne in the mixture (mean value from 58 g/kg DM for S100 to 18 g/kg DM for S25) and with growth stage (S100: 64 to 52 g/kg DM). OMD did not differ between different sainfoin/lucerne mixture ratios. Sainfoin and lucerne had an associative effect (significant quadratic contrast) on voluntary intake, N intake, total-tract N digestibility, N in faeces and urine (g/g N intake) and N retained (g/g N intake). Compared with lucerne mixtures (S0 and S25), high-sainfoin-content mixtures (S100 and S75) increased the in situ estimates of forage N escaping from the rumen (from 0.162, 0.188 for S0 and S25 to 0.257, 0.287 for S75 and S100) but decreased forage N intestinal digestibility (from 0.496, 0.446 for S0 and S25 to 0.469, 0.335 for S75 and S100). The amount of forage N disappearing from the bags in the SI (per g forage N) was the highest for high-sainfoin mixtures (from 0.082, 0.108 for S100 and S75 to 0.056, 0.058 for S25 and S0, P < 0.001). Rumen juice total N (tN) and ammonia N (NH3-N) values were the lowest in the high-sainfoin diet (mean tN 0.166 mg/g in S100 as compared with 0

    Arbuscular mycorrhiza and the rhizobia-legume symbiosis are two major root endosymbioses that facilitate plant nutrition. In Lotus japonicus, two symbiotic cation channels, CASTOR and POLLUX, are indispensable for the induction of nuclear calcium spiking, one of the earliest plant responses to symbiotic partner recognition. During recent evolution, a single amino acid substitution in DOES NOT MAKE INFECTIONS1 (DMI1), the POLLUX putative ortholog in the closely related Medicago truncatula, rendered the channel solo sufficient for symbiosis; castor, pollux, and castor pollux double mutants of L. japonicus were rescued by DMI1 alone, while both Lj-CASTOR and Lj-POLLUX were required for rescuing a dmi1 mutant of M. truncatula. Experimental replacement of the critical serine by an alanine in the selectivity filter of Lj-POLLUX conferred a symbiotic performance indistinguishable from DMI1. Electrophysiological characterization of DMI1 and Lj-CASTOR (wild-type and mutants) by planar lipid bilayer experiments combined with calcium imaging in Human Embryonic Kidney-293 cells expressing DMI1 (the wild type and mutants) suggest that the serine-to-alanine substitution conferred reduced conductance with a long open state to DMI1 and improved its efficiency in mediating calcium oscillations. We propose that this single amino acid replacement in the selectivity filter made DMI1 solo sufficient for symbiosis, thus explaining the selective advantage of this allele at the mechanistic level.

    At the Asian Vegetable Research and Development Center (AVRDC) Soybean, Glycine max (L.) Merr. and mungbean, Vigna radiata (L.) Wilczek are included in the Legume Program for improvement. Germplasm collection in soybean and mungbean are 9,524 and 5,108 respectively. Developing improved selections with early, uniform maturity, high yield, wide adaptability and resistance to diseases and insects are the major breeding objectives for the tropics and subtropics. Genetic diversity and genetic resources are available in the germplasm for most of the desired traits both in soybean as well as mungbean. However, for traits such as soybean rust resistance in soybean and resistance to insects in mungbean are rare. Limited amount of radiation breeding is being employed in cooperation with Korean Atomic Energy Agency to obtain desirable genes in both species. A number of AVRDC identified accessions and breeding lines are being used by the national programs to develop improved cultivars. AVRDC developed breeding selections have been released as new cultivars in Costa Rica, Fiji, Korea, India, Indonesia, Malaysia and Taiwan. (author)

    Full Text Available Gypsum combined with leguminous residue may extend rootability and improve growth and maize grain yield. The aim of this study was to evaluate the combined effects of gypsum and leguminous residue on soil rootability in the root zone and on maize grain yield in a cohesive tropical soil. We used seven treatments: (i control; (ii urea; (iii leguminous; (iv 6 t/ha of gypsum with leguminous or (v with urea or (vi with both; and (vii 12 t/ha of gypsum with urea and leguminous. Gypsum was applied in January 2010 and soil samples were analyzed in 2012–2015. Maize was sown in 2011–2013 and 2015, when maize yield was determined. Soil penetration strength and the analysis of plant tissue was performed in 2015. The leaf area index, nitrogen accumulation amount, total N concentration and amount of N remobilization were also determined in 2015. Gypsum with leguminous residue modified the root zone by increasing calcium and organic matter levels and by reducing soil penetration strength. The leaf area index and the remobilization of nitrogen to grains increased, due to greater uptake before and after tasseling. The gypsum and leguminous residue combination is a more suitable strategy to improve agrosystems in cohesive soils of the humid tropics.

The aim of this study was to determine the effects of combining TMR (10% CP and 13% ADF), and legume-based herbage (14% CP and 27% ADF) on intake, nutrient digestion, ruminal fermentation, microbial N flow and glucose and nitrogen metabolism in heifers. The experiment was a 3×3 Latin square design replicated three times; each period lasted 18 days (10 adaptation days and 8 measurement days). Nine cross-bred (Aberdeen Angus×Hereford) heifers (214±18 kg) fitted with permanent rumen catheters and housed in individual metabolic cages were assigned to one of three treatments: 24 h access to TMR ( T ), 24 h access to herbage ( H ) or combined diets with 18 h access to TMR and 6 h access to herbage ( T+H ). Data were evaluated using a mixed model. Animals fed T+H (TMR 71% and herbage 29%) diets tended to have a higher dry matter intake as a proportion of their BW than animals fed T. The T+H diet did not change ruminal fermentation (pH, N-NH3 and volatile fatty acids) or the N metabolism relative to the T diet, but increased the glucagon concentration and altered glucose metabolism. Conversely, animals fed T+H had increased purine derivatives excretion, increased N use efficiency for microbial protein synthesis and decreased plasma urea and urinary N excretion relative to animals fed H diet. The use of combined diets led to consumption of nutrients similar to a TMR diet, without reducing nutrient use and could improve N utilization compared with the herbage-only diet.

    Full Text Available Grain legumes, also called pulses, play a key role in the nutritional improvement of food and feed. These legumes are important sources of protein as well as other nutritional compounds. Today, protein is one of the most sought after ingredients in the market and grain legumes represent one of the most sustainable protein sources. However, not all grain legume proteins are nutritionally equal. Their quality varies and depends on their amino acid composition and digestibility. In this article, we review concepts related to grain legume protein quality and discuss challenges regarding their genetic improvement. A comprehensive database of grain legume amino acid profiles and protein digestibility is needed to address the matter of protein quality in grain legume breeding. This database will be enhanced by quantitative information on digestibility-reducing bioactive compounds and the development of reliable screening tools. The achievement of higher protein quality grain legume varieties, better adjusted to animal and human requirements, will cut dietary protein content, associated costs and nitrogen excretion, thus reducing the environmental impact.Las leguminosas grano tienen un alto potencial en alimentación humana y animal siendo una importante fuente de proteínas así como de otros compuestos beneficiosos para la nutrición y salud.

    Food legume crops play important roles in conservation farming systems and contribute to food security in the developing world. However, in many regions of the world, their production has been adversely affected by drought. Although water scarcity is a severe abiotic constraint of legume crops productivity, it remains unclear how the effects of drought co-vary with legume species, soil texture, agroclimatic region, and drought timing. To address these uncertainties, we collected literature data between 1980 and 2014 that reported monoculture legume yield responses to drought under field conditions, and analyzed this data set using meta-analysis techniques. Our results showed that the amount of water reduction was positively related with yield reduction, but the extent of the impact varied with legume species and the phenological state during which drought occurred. Overall, lentil (Lens culinaris), groundnut (Arachis hypogaea), and pigeon pea (Cajanus cajan) were found to experience lower drought-induced yield reduction compared to legumes such as cowpea (Vigna unguiculata) and green gram (Vigna radiate). Yield reduction was generally greater when legumes experienced drought during their reproductive stage compared to during their vegetative stage. Legumes grown in soil with medium texture also exhibited greater yield reduction compared to those planted on soil of either coarse or fine texture. In contrast, regions and their associated climatic factors did not significantly affect legume yield reduction. In the face of changing climate, our study provides useful information for agricultural planning and research directions for development of drought-resistant legume species to improve adaptation and resilience of agricultural systems in the drought-prone regions of the world.

    Full Text Available Legume cultivation has sharply decreased in Italy during the last 50 years. Lucerne remains widely grown (with about 12% of its area devoted to dehydration, whereas soybean is definitely the most-grown grain legume. Poor legume cropping is mainly due to the gap in yielding ability with major cereals, which has widened up in time according to statistical data. Lucerne displays definitely higher crude protein yield and somewhat lower economic gap with benchmark cereals than feed grain legumes. Pea because of high feed energy production per unit area and rate of genetic progress, and white lupin because of high protein yield per unit area, are particularly interesting for Italian rain-fed environments. Greater legume cultivation in Europe is urged by the need for reducing energy and green-house gas emissions and excessive and unbalanced global N flows through greater symbiotic N fixation and more integrated crop-animal production, as well as to cope with ongoing and perspective raising prices of feed proteins and N fertilisers and insecurity of feed protein supplies. The transition towards greater legume cultivation requires focused research effort, comprehensive stakeholder cooperation and fair economic compensation for legume environmental services, with a key role for genetic improvement dragged by public breeding or pre-breeding. New opportunities for yield improvement arise from the ongoing development of cost-efficient genome-enabled selection procedures, enhanced adaptation to specific cropping conditions via ecophysiological and evolutionary-based approaches, and more thorough exploitation of global genetic resources.

    Epidemiological research has shown a positive association between certain diseases and dietary intake of food components found in fruits, grains, legumes, fish oil among others. Food that may provide a health benefit beyond the traditional nutrients that it contains, are named functional food. In addition to the varied nutrients, legumes contain compounds such as polyphenols, soluble fiber, alpha-galactosides and isoflavones which confer propierties of functional foods. Do to the cuse of flatus production in some people, long cooking periods, or anti-nutritional factors, legume consumption levels are limited. In this review, germination and fermentation processes will be presented as alternatives that are able to reduce or inactivate anti-nutritional factors, preserve and even improve the content of the isoflavones, or better the potencial of the legumes as functional food or as ingredients for the formulation of functional foods.

    In Bangladesh grain legumes are the protein meat substitute of the poor, and an integral part of the daily diet. Yet present yields cannot meet demand and every year about 25% of the country's grain legumes' requirements have to be imported at a cost of about US $23 million in hard-earned foreign exchange. This money could easily be saved by increasing production in the country. The Department of Technical Co-operation is sponsoring a programme, with technical support from the Joint FAO/IAEA Division, in Bangladesh to find ways of increasing yields of grain legumes using efficient strains of biofertilizers.

  7. Oil body biogenesis and biotechnology in legume seeds.

    Science.gov (United States)

    Song, Youhong; Wang, Xin-Ding; Rose, Ray J

    2017-10-01

    The seeds of many legume species including soybean, Pongamia pinnata and the model legume Medicago truncatula store considerable oil, apart from protein, in their cotyledons. However, as a group, legume storage strategies are quite variable and provide opportunities for better understanding of carbon partitioning into different storage products. Legumes with their ability to fix nitrogen can also increase the sustainability of agricultural systems. This review integrates the cell biology, biochemistry and molecular biology of oil body biogenesis before considering biotechnology strategies to enhance oil body biosynthesis. Cellular aspects of packaging triacylglycerol (TAG) into oil bodies are emphasized. Enhancing seed oil content has successfully focused on the up-regulation of the TAG biosynthesis pathways using overexpression of enzymes such as diacylglycerol acyltransferase1 and transcription factors such as WRINKLE1 and LEAFY COTYLEDON1. While these strategies are central, decreasing carbon flow into other storage products and maximizing the packaging of oil bodies into the cytoplasm are other strategies that need further examination. Overall there is much potential for integrating carbon partitioning, up-regulation of fatty acid and TAG synthesis and oil body packaging, for enhancing oil levels. In addition to the potential for integrated strategies to improving oil yields, the capacity to modify fatty acid composition and use of oil bodies as platforms for the production of recombinant proteins in seed of transgenic legumes provide other opportunities for legume biotechnology.

    Globally, 800 million people are malnourished. Heavily subsidised farmers in rich countries produce sufficient surplus food to feed the hungry, but not at a price the poor can afford. Even donating the rich world's surplus to the poor would not solve the problem. Most poor people earn their living from agriculture, so a deluge of free food would destroy their livelihoods. Thus, the only answer to world hunger is to safeguard and improve the productivity of farmers in poor countries. Diets of subsistence level farmers in Africa and Latin America often contain sufficient carbohydrates (through cassava, corn/maize, rice, wheat, etc.), but are poor in proteins. Dietary proteins can take the form of scarce animal products (eggs, milk, meat, etc.), but are usually derived from legumes (plants of the bean and pea family). Legumes are vital in agriculture as they form associations with bacteria that 'fix-nitrogen' from the air. Effectively this amounts to internal fertilisation and is the main reason that legumes are richer in proteins than all other plants. Thousands of legume species exist but more common beans (Phaseolus vulgaris L.) are eaten than any other. In some countries such as Mexico and Brazil, beans are the primary source of protein in human diets. As half the grain legumes consumed worldwide are common beans, they represent the species of choice for the study of grain legume nutrition. Unfortunately, the yields of common beans are low even by the standards of legumes, and the quality of their seed proteins is sub-optimal. Most probably this results from millennia of selection for stable rather than high yield, and as such, is a problem that can be redressed by modem genetic techniques. We have formed an international consortium called 'Phaseomics' to establish the necessary framework of knowledge and materials that will result in disease-resistant, stress-tolerant, high-quality protein and high-yielding beans. Phaseomics will be instrumental in improving

    Medicago truncatula has been developed into a model legume. Its close relative alfalfa (Medicago sativa) is the most widely grown forage legume crop in the United States. By screening a large population of M. truncatula mutants tagged with the transposable element of tobacco (Nicotiana tabacum) cell type1 (Tnt1), we identified a mutant line (NF2089) that maintained green leaves and showed green anthers, central carpels, mature pods, and seeds during senescence. Genetic and molecular analyses revealed that the mutation was caused by Tnt1 insertion in a STAY-GREEN (MtSGR) gene. Transcript profiling analysis of the mutant showed that loss of the MtSGR function affected the expression of a large number of genes involved in different biological processes. Further analyses revealed that SGR is implicated in nodule development and senescence. MtSGR expression was detected across all nodule developmental zones and was higher in the senescence zone. The number of young nodules on the mutant roots was higher than in the wild type. Expression levels of several nodule senescence markers were reduced in the sgr mutant. Based on the MtSGR sequence, an alfalfa SGR gene (MsSGR) was cloned, and transgenic alfalfa lines were produced by RNA interference. Silencing of MsSGR led to the production of stay-green transgenic alfalfa. This beneficial trait offers the opportunity to produce premium alfalfa hay with a more greenish appearance. In addition, most of the transgenic alfalfa lines retained more than 50% of chlorophylls during senescence and had increased crude protein content. This study illustrates the effective use of knowledge gained from a model system for the genetic improvement of an important commercial crop. PMID:21957014

    2014-01-01

    European grassland-based livestock production systems face the challenge of producing more meat and milk to meet increasing world demands and to achieve this using fewer resources. Legumes offer great potential for achieving these objectives. They have numerous features that can act together at different stages in the soil–plant–animal–atmosphere system, and these are most effective in mixed swards with a legume proportion of 30–50%. The resulting benefits include reduced dependence on fossil energy and industrial N-fertilizer, lower quantities of harmful emissions to the environment (greenhouse gases and nitrate), lower production costs, higher productivity and increased protein self-sufficiency. Some legume species offer opportunities for improving animal health with less medication, due to the presence of bioactive secondary metabolites. In addition, legumes may offer an adaptation option to rising atmospheric CO2 concentrations and climate change. Legumes generate these benefits at the level of the managed land-area unit and also at the level of the final product unit. However, legumes suffer from some limitations, and suggestions are made for future research to exploit more fully the opportunities that legumes can offer. In conclusion, the development of legume-based grassland–livestock systems undoubtedly constitutes one of the pillars for more sustainable and competitive ruminant production systems, and it can be expected that forage legumes will become more important in the future.

    Small monomeric GTPases act as molecular switches in several processes that involve polar cell growth, participating mainly in vesicle trafficking and cytoskeleton rearrangements. This gene superfamily has largely expanded in plants through evolution as compared with other Kingdoms, leading to the suggestion that members of each subfamily might have acquired new functions associated to plant-specific processes. Legume plants engage in a nitrogen-fixing symbiotic interaction with rhizobia in a process that involves polar growth processes associated with the infection throughout the root hair. To get insight into the evolution of small GTPases associated with this process, we use a comparative genomic approach to establish differences in the Ras GTPase superfamily between legume and non-legume plants. Phylogenetic analyses did not show clear differences in the organization of the different subfamilies of small GTPases between plants that engage or not in nodule symbiosis. Protein alignments revealed a strong conservation at the sequence level of small GTPases previously linked to nodulation by functional genetics. Interestingly, one Rab and three Rop proteins showed conserved amino acid substitutions in legumes, but these changes do not alter the predicted conformational structure of these proteins. Although the steady-state levels of most small GTPases do not change in response to rhizobia, we identified a subset of Rab, Rop and Arf genes whose transcript levels are modulated during the symbiotic interaction, including their spatial distribution along the indeterminate nodule. This study provides a comprehensive study of the small GTPase superfamily in several plant species. The genetic program associated to root nodule symbiosis includes small GTPases to fulfill specific functions during infection and formation of the symbiosomes. These GTPases seems to have been recruited from members that were already present in common ancestors with plants as distant as monocots

    Salt stress is an ever-present threat to crop yields, especially in countries with irrigated agriculture. Efforts to improve salt tolerance in crop plants are vital for sustainable crop production on marginal lands to ensure future food supplies. Grain legumes are a fascinating group of plants due to their high grain protein contents and ability to fix biological nitrogen. However, the accumulation of excessive salts in soil and the use of saline groundwater are threatening legume production worldwide. Salt stress disturbs photosynthesis and hormonal regulation and causes nutritional imbalance, specific ion toxicity and osmotic effects in legumes to reduce grain yield and quality. Understanding the responses of grain legumes to salt stress and the associated tolerance mechanisms, as well as assessing management options, may help in the development of strategies to improve the performance of grain legumes under salt stress. In this manuscript, we discuss the effects, tolerance mechanisms and management of salt stress in grain legumes. The principal inferences of the review are: (i) salt stress reduces seed germination (by up to more than 50%) either by inhibiting water uptake and/or the toxic effect of ions in the embryo, (ii) salt stress reduces growth (by more than 70%), mineral uptake, and yield (by 12-100%) due to ion toxicity and reduced photosynthesis, (iii) apoplastic acidification is a good indicator of salt stress tolerance, (iv) tolerance to salt stress in grain legumes may develop through excretion and/or compartmentalization of toxic ions, increased antioxidant capacity, accumulation of compatible osmolytes, and/or hormonal regulation, (v) seed priming and nutrient management may improve salt tolerance in grain legumes, (vi) plant growth promoting rhizobacteria and arbuscular mycorrhizal fungi may help to improve salt tolerance due to better plant nutrient availability, and (vii) the integration of screening, innovative breeding, and the development of

  17. NPR1 Protein Regulates Pathogenic and Symbiotic Interactions between Rhizobium and Legumes and Non-Legumes

    OpenAIRE

    2009-01-01

    BACKGROUND: Legumes are unique in their ability to establish symbiotic interaction with rhizobacteria from Rhizobium genus, which provide them with available nitrogen. Nodulation factors (NFs) produced by Rhizobium initiate legume root hair deformation and curling that entrap the bacteria, and allow it to grow inside the plant. In contrast, legumes and non-legumes activate defense responses when inoculated with pathogenic bacteria. One major defense pathway is mediated by salicylic acid (SA)....

    1994-01-01

    The effects of adding two legumes, Gliricidia sepium and Leucaena leucocephala, cv. Cunningham, and molasses on the fermentation characteristics of silages made from two tropical grasses (Pangola grass, Digitaria decumbens, and Setaria sphacelata cv. Kazungula) were investigated. Pangola grass silages contained significantly higher contents of water-soluble carbohydrates and lactic acid than did setaria silages after 100 days fermentation, but there were no significant differences between the two silages in populations of lactic acid bacteria and contents of total N and NH3-N. Addition of either species of legume had no significant effect on fermentation acids and NH3-N contents, and numbers of lactic acid bacteria. Addition of both legumes reduced NH3-N production in the silages by 59% after 5 days' fermentation. Numbers of lactic acid bacteria were not significantly affected by the different treatments. Enterococcus faecalis represented 60% of the lactic acid bacteria isolated from the treated herbages prior to ensiling. By 100 days of fermentation, only lactobacilli were isolated: 82% homo-fermenters and 18% hetero-fermenters. Lactobacillus mesenteroides subsp. dextranicum was found only in the silage supplemented with 33% (w/w) legume. It was concluded that the low quality of tropical grasses used as feeds for ruminants may be significantly improved by ensiling these grasses with small amounts of molasses and with high-protein tree leaves.

    A study was conducted to analyze the energy required to produce different legumes in 11 different regions of Turkey. The objective was to improve energy efficiency. Data was collected for the production of dry bean, chickpea and soybean under rainfed and irrigated conditions, as well as for the production of lentil under rainfed conditions. The data was evaluated in terms of energy use efficiency, energy productivity and specific energy for different regions of Turkey. The main energy sources are human, diesel, fertilizer, seed, machine, chemicals and water. The main agricultural operations are seedbed preparation, seeding, fertilization, hoeing, irrigation, spraying, harvesting, threshing and transporting. The total energy input ranged between 3361.5 and 25229.7 MJ/ha. Based on product yields, the energy use efficiency varied between 0.96 and 4.32.

    2008-12-01

    Full Text Available Legumes are important in world agriculture, providing biologically fixed nitrogen, breaking cereal disease cycles and contributing locally grown food and feed, including forage. Pea and faba bean were grown by early farmers in Finland, with remains dated to 500 BC. Landraces of pea and faba bean were gradually replaced by better adapted, higher quality materials for food use. While grain legumes have been restricted by their long growing seasons to the south of the country, red, white and alsike clovers are native throughout and have long been used in leys for grazing, hay and silage. Breeding programmes released many cultivars of these crops during the 1900s, particularly pea and red clover. A.I. Virtanen earned the 1945 Nobel Prize in Chemistry for his work on both nitrogen fixation and silage preservation. Use of crop mixtures may appear modern, but farmers used them already in the early 1800s, when oat was used to support pea, and much effort has been devoted to improving the system and establishing its other benefits. Although international cultivars have been easily accessible since Finland’s 1995 entry into the European Union, the combination of feed quality and appropriate earliness is still needed, as < 1% of arable land is sown to grain legumes and an increase to 9–10% would allow replacement of imported protein feeds. Climate change will alter the stresses on legume crops, and investment in agronomy, physiology and breeding is needed so that farmers can gain from the many advantages of a legume-supported rotation.;

    Full Text Available Legumes have been an important part of cropping systems since the dawn of agriculture. The shift in Europe from draught animals to meat animals coincided with the increasing availability of soybean meal from North and South America, and the Common Agricultural Policy of the European Union promoted the growing of cereals and oilseeds at the expense of other crops so legumes fell out of favour with farmers and decision-makers. Continental concerns about food and feed security, high prices of oil and soybean meal and advances in the application of fundamental molecular genetics to crop species, all mean that now is a good opportunity to promote the return of legumes to European cropping systems by enhancing the efficiency of research and development on this family. Hence we propose the establishment of a Legume Society that will promote information exchange and scientific productivity by uniting the various legume research communities.

    Legumes are characterized as keeping stable nutrient supply under nutrient-limited conditions. However, few studies examined the legumes' stoichiometric advantages over other plants across various taxa in natural ecosystems. We explored differences in nitrogen (N) and phosphorus (P) stoichiometry of different tissue types (leaf, stem, and root) between N2-fixing legume shrubs and non-N2-fixing shrubs from 299 broadleaved deciduous shrubland sites in northern China. After excluding effects of taxonomy and environmental variables, these two functional groups differed considerably in nutrient regulation. N concentrations and N:P ratios were higher in legume shrubs than in non-N2-fixing shrubs. N concentrations were positively correlated between the plants and soil for non-N2-fixing shrubs, but not for legume shrubs, indicating a stronger stoichiometric homeostasis in legume shrubs than in non-N2-fixing shrubs. N concentrations were positively correlated among three tissue types for non-N2-fixing shrubs, but not between leaves and non-leaf tissues for legume shrubs, demonstrating that N concentrations were more dependent among tissues for non-N2-fixing shrubs than for legume shrubs. N and P concentrations were correlated within all tissues for both functional groups, but the regression slopes were flatter for legume shrubs than non-N2-fixing shrubs, implying that legume shrubs were more P limited than non-N2-fixing shrubs. These results address significant differences in stoichiometry between legume shrubs and non-N2-fixing shrubs, and indicate the influence of symbiotic nitrogen fixation (SNF) on plant stoichiometry. Overall, N2-fixing legume shrubs are higher and more stoichiometrically homeostatic in N concentrations. However, due to excess uptake of N, legumes may suffer from potential P limitation. With their N advantage, legume shrubs could be good nurse plants in restoration sites with degraded soil, but their P supply should be taken care of during management

    Instrument setpoints have a definite and often significant impact on plant safety, reliability, and availability. Although typically overshadowed by plant design, modification, and physical change activities, instrument setpoints can alter plant status and system operating characteristics just as significantly. Recognizing the need for a formal program that provides configuration control of instrument setpoints, provides a readily accessible and clearly documented basis for instrument setpoints, and integrates and coordinates operations, engineering, and maintenance activities that influence the basis for instrument setpoints, Philadelphia Electric Company (PECo) is developing an Improved Instrument Setpoint Control Program (IISCP) that incorporates current industry guidance and practices and state-of-the-art information systems technology. The IISCP was designed around PECo's then existing business processes for setpoint control, determination, and maintenance. A task force representing the various constituencies from both plants and the engineering and services organizations were formed to identify objectives and design features for the IISCP. Utilizing industry standards and guidance, regulatory documents, the experiences and good practices obtained from other utilities, and PECo's nuclear group strategies, objectives, and goals, specific objectives were identified to enhance the business processes

    The web program GeMprospector (URL: http://cgi-www.daimi.au.dk/cgi-chili/GeMprospector/main) allows users to automatically design large sets of cross-species genetic marker candidates targeting either legumes or grasses. The user uploads a collection of ESTs from one or more legume or grass species, and they are compared with a database of clusters of homologous EST and genomic sequences from other legumes or grasses, respectively. Multiple sequence alignments between submitted ESTs and their homologues in the appropriate database form the basis of automated PCR primer design in conserved exons such that each primer set amplifies an intron. The only user input is a collection of ESTs, not necessarily from more than one species, and GeMprospector can boost the potential of such an EST collection by combining it with a large database to produce cross-species genetic marker candidates for legumes or grasses.

  13. Biological Nitrogen Fixation on Legume

    Directory of Open Access Journals (Sweden)

    Armiadi

    2009-03-01

    Full Text Available Nitrogen (N is one of the major limiting factors for crop growth and is required in adequate amount, due to its function as protein and enzyme components. In general, plants need sufficient nitrogen supply at all levels of growth, especially at the beginning of growth phase. Therefore, the availability of less expensive N resources would reduce the production cost. The increasing use of chemical fertilizer would probably disturb soil microorganisms, reduce the physical and chemical characteristics of soil because not all of N based fertilizer applied can be absorbed by the plants. Approximately only 50% can be used by crops, while the rest will be altered by microorganism into unavailable N for crops or else dissappear in the form of gas. Leguminous crops have the capacity to immobilize N2 and convert into the available N if innoculated with Rhizobium. The amount of N2 fixed varies depending on legume species and their environment.

    2014-01-01

    Scent glands, or osmophores, are predominantly floral secretory structures that secrete volatile substances during anthesis, and therefore act in interactions with pollinators. The Leguminosae family, despite being the third largest angiosperm family, with a wide geographical distribution and diversity of habits, morphology and pollinators, has been ignored with respect to these glands. Thus, we localised and characterised the sites of fragrance production and release in flowers of legumes, in which scent plays an important role in pollination, and also tested whether there are relationships between the structure of the scent gland and the pollinator habit: diurnal or nocturnal. Flowers in pre-anthesis and anthesis of 12 legume species were collected and analysed using immersion in neutral red, olfactory tests and anatomical studies (light and scanning electron microscopy). The main production site of floral scent is the perianth, especially the petals. The scent glands are distributed in a restricted way in Caesalpinia pulcherrima, Anadenanthera peregrina, Inga edulis and Parkia pendula, constituting mesophilic osmophores, and in a diffuse way in Bauhinia rufa, Hymenaea courbaril, Erythrostemon gilliesii, Poincianella pluviosa, Pterodon pubescens, Platycyamus regnellii, Mucuna urens and Tipuana tipu. The glands are comprised of cells of the epidermis and mesophyll that secrete mainly terpenes, nitrogen compounds and phenols. Relationships between the presence of osmophores and type of anthesis (diurnal and nocturnal) and the pollinator were not found. Our data on scent glands in Leguminosae are original and detail the type of diffuse release, which has been very poorly studied. © 2013 German Botanical Society and The Royal Botanical Society of the Netherlands.

    To assess the nutritional quality of food aid delivered by food banks in France and to identify practical modifications to improve it. National-level data were collected for all food aid distributed by French food banks in 2004, and its nutrient content per 2000 kcal was estimated and compared with French recommendations for adults. Starting with the actual donation and allowing new foods into the food aid donation, linear programming was used to identify the minimum changes required in the actual donation to achieve the French recommendations. French food-bank-delivered food aid does not achieve the French recommendations for dietary fibre, ascorbic acid, vitamin D, folate, magnesium, docosahexaenoic acid, alpha-linolenic acid and the percentage of energy from saturated fatty acids. Linear programming analysis showed that these recommendations are achievable if more fruits, vegetables, legumes and fish were collected and less cheese, refined cereals and foods rich in fat, sugar and/or salt. In addition, new foods not previously collected are needed, particularly nuts, wholemeal bread and rapeseed oil. These changes increased the total edible weight (42%) and economic value (55%) of the food aid donation, with one-third of its edible weight coming from fruits and vegetables, one-third from staples, one-quarter from dairy products and approximately a tenth from meat/fish/eggs. Important changes in the types and amounts of food collected will improve the nutritional quality of food-bank-delivered food aid in France. Such changes are recommended to improve the diets of deprived French populations.

  16. Health benefits of legumes and pulses with a focus on Australian sweet lupins.

    Kouris-Blazos, Antigone; Belski, Regina

    2016-01-01

    The 68th United Nations General Assembly declared 2016 the International Year of Pulses. Therefore it is timely to review the current evidence of the benefits of legumes for human health with a focus on Australian sweet lupins. Medline, Pubmed, Cochrane library were searched to identify cross-sectional/epidemiological studies, randomised controlled trials (RCTs) and systematic reviews. The strongest evidence appears to be for links between eating legumes and reduced risk of colorectal cancer as well as eating soy foods and reduced LDL cholesterol. However, epidemiological studies and RCTs suggest that replacing several meat-based meals a week with legumes can have a positive impact on longevity, diabetes, cardiovascular disease and weight management, potentially via favourable effects on the gut microbiome. Sweet lupins are unique among legumes with one of the highest combined amounts of digestible plant protein (38%) and dietary fibre (30%). Unlike other legumes, their low amount of anti-nutritional factors negates the need for soaking/cooking and they can therefore be eaten uncooked. Sweet lupins may lower blood pressure, improve blood lipids and insulin sensitivity and favourably alter the gut microbiome. There is growing interest in pulses, especially sweet lupins, as ingredients to improve the nutritional value of baked goods (particularly gluten free) and to create novel products to replace meat. Legumes form part of most traditional diets. They, including sweet lupins, can play a useful role in health maintenance.

    The operational oceanography has been engaged in the development of new acquisition, transmission and assimilation systems in order to have the widest possible coverage of real time informations, reflecting the guidelines of the World Meteorological Organization (WMO) and of the Intergovernmental Oceanographic Commission (IOC). Physical and biological processes of marine ecosystems have a high spatial and temporal variability, whose study is possible only through high resolution and synoptic observations. More than for the physical variables, the biological ones have to be observed in situ. Especially in the mid-high latitudes, a deep observation of the water column is needed, because of the typical distribution of phytoplankton's biomass (Mann and Lazier, 1991). In the last times an extensive use of XBT was performed in order to provide near real time analysis of the ocean temperature, but there is still a lack in the biomass estimation. T-FLAP technology (Temperature and Fluorescence LAunchable Probe - Marcelli et al. 2007) was designed to answer to the claim of a cost effective temperature and fluorescence autonomous probe, to be used on ships of opportunity for the Voluntary Observing Ship Program (VOS). During the last three years the probe was upgraded and improved both in materials and in measure sensitivity. New LEDs were mounted to increase the radiant power of the excitation source.. In order to evaluate the red filter efficiency to detect fluorescence chlorophyll a emission wavelengths, transmittance of new available filters in the range 682-685 nm was calculated. In vivo fluorescence spectra of each filter were also performed on samples from Chlorella sp. cultures, to assess the percentage of the fluorescence emission peak transmitted by the filters. A multiple system was designed and realized for a high accuracy dynamic calibration of the probes.

    Legume Information System (LIS), at http://legumeinfo.org, is a genomic data portal (GDP) for the legume family. LIS provides access to genetic and genomic information for major crop and model legumes. With more than two-dozen domesticated legume species, there are numerous specialists working on particular species, and also numerous GDPs for these species. LIS has been redesigned in the last three years both to better integrate data sets across the crop and model legumes, and to better accommodate specialized GDPs that serve particular legume species. To integrate data sets, LIS provides genome and map viewers, holds synteny mappings among all sequenced legume species and provides a set of gene families to allow traversal among orthologous and paralogous sequences across the legumes. To better accommodate other specialized GDPs, LIS uses open-source GMOD components where possible, and advocates use of common data templates, formats, schemas and interfaces so that data collected by one legume research community are accessible across all legume GDPs, through similar interfaces and using common APIs. This federated model for the legumes is managed as part of the 'Legume Federation' project (accessible via http://legumefederation.org), which can be thought of as an umbrella project encompassing LIS and other legume GDPs.

    Cullis, Christopher; Kunert, Karl J

    2017-04-01

    Orphan, or underutilized, legumes are domesticated legumes with useful properties, but with less importance than major world crops due to use and supply constraints. However, they play a significant role in many developing countries, providing food security and nutrition to consumers, as well as income to resource-poor farmers. They have been largely neglected by both researchers and industry due to their limited economic importance in the global market. Orphan legumes are better adapted than the major legume crops to extreme soil and climatic conditions, with high tolerance to abiotic environmental stresses such as drought. As a stress response they can also produce compounds with pharmaceutical value. Orphan legumes are therefore a likely source of important traits for introduction into major crops to aid in combating the stresses associated with global climate change. Modern large-scale genomics techniques are now being applied to many of these previously understudied crops, with the first successes reported in the genomics area. However, greater investment of resources and manpower are necessary if the potential of orphan legumes is to be unlocked and applied in the future. © The Author 2016.

    Full Text Available The two temperate forage legumes containing condensed tannins (CT that promote ruminant production are birdsfoot trefoil (Lotus corniculatus L.; BFT and sainfoin (Onobrychis viciifolia Scop.; SF. Both are well-adapted to the cool-temperate climate and alkaline soils of the Mountain West USA. Condensed tannins comprise a diverse family of bioactive chemicals with multiple beneficial functions for ruminants, including suppression of internal parasites and enteric methane. Birdsfoot trefoil contains 10 to 40 g·CT·kg−1 dry matter (DM, while SF contains 30 to 80 g·CT·kg−1 DM. Our studies have focused on these two plant species and have demonstrated consistently elevated rates of gain for beef calves grazing both BFT and SF. Novel results from our BFT research include carcass dressing percentages and consumer sensory evaluations equivalent to feedlot-finished steers and significantly greater than grass-finished steers, but with omega-3 fatty acid concentrations equal to grass-finished beef. We have further demonstrated that ruminants fed BFT or SF will consume more endophyte-infected tall fescue (Schedonorus arundinaceus (Schreb. Dumort. forage or seed than ruminants fed a non-CT forage legume. There is great potential value for sustainable livestock production in the use of highly digestible, nitrogen-fixing legumes containing tannins demonstrated to improve ruminant productivity.

    Full Text Available In developing countries like India, with increasing urbanization, the demand for processed food and bakery products particularly cookies command wide popularity in both urban and rural mass. Hence, an attempt was made to develop functionally and nutritionally improved cookies and the influence of the partial replacement of the wheat flour by legume on the quality characteristic of cookies was analyzed. Six blends were prepared by homogenously mixing chickpea flour, pigeon pea, moong bean flour, and cowpea flour with wheat flour in the percentage proportions: 100, 25:75, 25:75, 25:75, 25:75, and 10:10:10:10:60 (CPF:WWF, PF:WWF, MF:WWF, CF:WWF, and CPF:PF:MF:CF:WWF and later used to make cookies. Chemical and functional properties of the composite flours and chemical as well as sensory characteristics of cookies made from the above combinations were determined. The incorporation of legume flour significantly affected the physical, chemical, and phytonutrient parameters of the cookies. The results revealed that functional properties, viz. water absorption capacity, oil absorption capacity, and swelling property, increased with addition of legume flours. The physical analysis revealed that the diameter and height increased with the incorporation of legume flour. The results of the proximate composition showed that the A6 possesses highest percentage of proteins (13.42% and crude fat (22.90%, A5 contains maximum value of crude fiber (2.10% and DPPH radical scavenging activity (55.47%, A1 showed maximum moisture (10.60%, A2 total phenolic content (6.14 TAE mg/100 g, and A3 showed maximum ash (3.66%.

    2018-03-01

    Full Text Available Annual cereal and legume grain production is dependent on inorganic nitrogen (N and other fertilizers inputs to resupply nutrients lost as harvested grain, via soil erosion/runoff, and by other natural or anthropogenic causes. Temperate-adapted perennial grain legumes, though currently non-existent, might be uniquely situated as crop plants able to provide relief from reliance on synthetic nitrogen while supplying stable yields of highly nutritious seeds in low-input agricultural ecosystems. As such, perennial grain legume breeding and domestication programs are being initiated at The Land Institute (Salina, KS, USA and elsewhere. This review aims to facilitate the development of those programs by providing criteria for evaluating potential species and in choosing candidates most likely to be domesticated and adopted as herbaceous, perennial, temperate-adapted grain legumes. We outline specific morphological and ecophysiological traits that may influence each candidate’s agronomic potential, the quality of its seeds and the ecosystem services it can provide. Finally, we suggest that perennial grain legume breeders and domesticators should consider how a candidate’s reproductive biology, genome structure and availability of genetic resources will determine its ease of breeding and its domestication timeline.

    The goals and operations of the Software Engineering Laboratory (SEL) is reviewed. For nearly 20 years the SEL has worked to understand, assess, and improve software and the development process within the production environment of the Flight Dynamics Division (FDD) of NASA's Goddard Space Flight Center. The SEL was established in 1976 with the goals of reducing: (1) the defect rate of delivered software, (2) the cost of software to support flight projects, and (3) the average time to produce mission-support software. After studying over 125 projects of FDD, the results have guided the standards, management practices, technologies, and the training within the division. The results of the studies have been a 75 percent reduction in defects, a 50 percent reduction in cost, and a 25 percent reduction in development time. Over time the goals of SEL have been clarified. The goals are now stated as: (1) Understand baseline processes and product characteristics, (2) Assess improvements that have been incorporated into the development projects, (3) Package and infuse improvements into the standard SEL process. The SEL improvement goal is to demonstrate continual improvement of the software process by carrying out analysis, measurement and feedback to projects with in the FDD environment. The SEL supports the understanding of the process by study of several processes including, the effort distribution, and error detection rates. The SEL assesses and refines the processes. Once the assessment and refinement of a process is completed, the SEL packages the process by capturing the process in standards, tools and training.

    Lv, Ming; Li, Yi; Kou, Bo; Zhou, Zhili

    2017-01-01

    Patients received by radiotherapy departments are diverse and may be diagnosed with different cancers. Therefore, they need different radiotherapy treatment plans and thus have different needs for medical resources. This research aims to explore the best method of scheduling the admission of patients receiving radiotherapy so as to reduce patient loss and maximize the usage efficiency of service resources. A mix integer programming (MIP) model integrated with special features of radiotherapy is constructed. The data used here is based on the historical data collected and we propose an exact method to solve the MIP model. Compared with the traditional First Come First Served (FCFS) method, the new method has boosted patient admission as well as the usage of linear accelerators (LINAC) and beds. The integer programming model can be used to describe the complex problem of scheduling radio-receiving patients, to identify the bottleneck resources that hinder patient admission, and to obtain the optimal LINAC-bed radio under the current data conditions. Different management strategies can be implemented by adjusting the settings of the MIP model. The computational results can serve as a reference for the policy-makers in decision making.

    Contingency management interventions effectively reduce or eliminate some individuals' problem substance use. Typically, those who do not benefit never experience the reward or planned contingency available through the intervention because they never produce the behavior (often abstinence) on which the reward is contingent. With two analog studies, we examine whether the effectiveness contingency management interventions improves when contingencies are arranged in ways that improve the likelihood of all participants experiencing the available reward. Participants were smokers not planning to quit. In Study 1, smokers were paid 0, 1, 3, 10, or 30 dollars each day for 5 days for delivery of breath carbon monoxide (CO) levels either contingency management system was made effective based on these results. Study 2 examined the effectiveness of percentile schedules at reducing breath CO levels. Percentile schedules shaped lower breath CO levels. The effectiveness of percentile schedules in shaping abstinence was tested in treatment seekers, and percentile schedules were found to be effective at shaping abstinence.

    Improving quality of care and maximizing efficiency are priorities in hip and knee replacement, where surgical demand and costs increase as the population ages. The authors describe the integrated structure and processes from the Continuous Quality Improvement (CQI) Program for Hip and Knee Replacement Surgical Care and summarize lessons learned from implementation. The Triple Aim framework and 6 dimensions of quality care are overarching constructs of the CQI program. A validated, evidence-based clinical pathway that measures quality across the continuum of care was adopted. Working collaboratively, multidisciplinary experts embedded the CQI program into everyday practices in clinics across Alberta. Currently, 83% of surgeons participate in the CQI program, representing 95% of the total volume of hip and knee surgeries. Biannual reports provide feedback to improve care processes, infrastructure planning, and patient outcomes. CQI programs evaluating health care services inform choices to optimize care and improve efficiencies through continuous knowledge translation. © The Author(s) 2014.

    Although there has been tremendous progress in quality improvement (QI) education for students and trainees in recent years, much less has been published regarding the training of active clinicians in QI. The Partners Clinical Process Improvement Leadership Program (CPIP) is a 6-day experiential program. Interdisciplinary teams complete a QI project framed by didactic sessions, interactive exercises, case-based problem sessions, and a final presentation. A total of 239 teams composed of 516 individuals have graduated CPIP. On completion, participant satisfaction scores average 4.52 (scale 1-5) and self-reported understanding of QI concepts improved. At 6 months after graduation, 66% of survey respondents reported sustained QI activity. Three opportunities to improve the program have been identified: (1) increasing faculty participation through online and tiered course offerings, (2) integrating the faculty-focused program with the trainee curriculum, and (3) developing a postgraduate curriculum to address the challenges of sustained improvement.

  2. Nitrogen modulation of legume root architecture signalling pathways involves phytohormones and small regulatory molecules

    Directory of Open Access Journals (Sweden)

    Nadiatul Akmal Mohd-Radzman

    2013-10-01

    Full Text Available Nitrogen, particularly nitrate is an important yield determinant for crops. However, current agricultural practice with excessive fertilizer usage has detrimental effects on the environment. Therefore, legumes have been suggested as a sustainable alternative for replenishing soil nitrogen. Legumes can uniquely form nitrogen-fixing nodules through symbiotic interaction with specialized soil bacteria. Legumes possess a highly plastic root system which modulates its architecture according to the nitrogen availability in the soil. Understanding how legumes regulate root development in response to nitrogen availability is an important step to improving root architecture. The nitrogen-mediated root development pathway starts with sensing soil nitrogen level followed by subsequent signal transduction pathways involving phytohormones, microRNAs and regulatory peptides that collectively modulate the growth and shape of the root system. This review focuses on the current understanding of nitrogen-mediated legume root architecture including local and systemic regulations by different N-sources and the modulations by phytohormones and small regulatory molecules.

  3. Anti-inflammatory effects of phytochemicals from fruits, vegetables, and food legumes: A review.

    Zhu, Fengmei; Du, Bin; Xu, Baojun

    2017-06-12

    Inflammation is the first biological response of the immune system to infection, injury or irritation. Evidence suggests that the anti-inflammatory effect is mediated through the regulation of various inflammatory cytokines, such as nitric oxide, interleukins, tumor necrosis factor alpha-α, interferon gamma-γ as well as noncytokine mediator, prostaglandin E 2 . Fruits, vegetables, and food legumes contain high levels of phytochemicals that show anti-inflammatory effect, but their mechanisms of actions have not been completely identified. The aim of this paper was to summarize the recent investigations and findings regarding in vitro and animal model studies on the anti-inflammatory effects of fruits, vegetables, and food legumes. Specific cytokines released for specific type of physiological event might shed some light on the specific use of each source of phytochemicals that can benefit to counter the inflammatory response. As natural modulators of proinflammatory gene expressions, phytochemical from fruits, vegetables, and food legumes could be incorporated into novel bioactive anti-inflammatory formulations of various nutraceuticals and pharmaceuticals. Finally, these phytochemicals are discussed as the natural promotion strategy for the improvement of human health status. The phenolics and triterpenoids in fruits and vegetables showed higher anti-inflammatory activity than other compounds. In food legumes, lectins and peptides had anti-inflammatory activity in most cases. However, there are lack of human study data on the anti-inflammatory activity of phytochemicals from fruits, vegetables, and food legumes.

    Sunn hemp (Crotolaria juncea), is a fast growing, high biomass yielding tropical legume that may be a possible southeastern bioenergy crop. When comparing this legume to a commonly grown summer legume - cowpeas (Vigna unguiculata), sunn hemp was superior in biomass yield (kg ha{sup -1}) and subsequent energy yield (GJ ha{sup -1}). In one year of the study after 12 weeks of growth, sunn hemp had 10.7 Mg ha{sup -1} of biomass with an energy content of 19.0 Mg ha{sup -1}. This resulted in an energy yield of 204 GJ ha{sup -1}. The energy content was 6% greater than that of cowpeas. Eventhough sunn hemp had a greater amount of ash, plant mineral concentrations were lower in some cases of minerals (K, Ca, Mg, S) known to reduce thermochemical conversion process efficiency. Pyrolytic degradation of both legumes revealed that sunn hemp began to degrade at higher temperatures as well as release greater amounts of volatile matter at a faster rate. (author)

It can be challenging to help people adjust their diet to meet their nutrient needs and promote weight loss, while at the same time still keeping them satiated. Nutrient rich legumes can be a valuable part of such a diet. They contain soluble fibre and protein and are low glycemic index, all of which may help promote satiety. Legumes are one of the most sustainable sources of protein in the world. Legumes are also significant sources of resistant starch, which is fermented by colonic bacteria to short chain fatty acids.

    Peleg-Grossman, Smadar; Golani, Yael; Kaye, Yuval; Melamed-Book, Naomi; Levine, Alex

    2009-12-21

    Legumes are unique in their ability to establish symbiotic interaction with rhizobacteria from Rhizobium genus, which provide them with available nitrogen. Nodulation factors (NFs) produced by Rhizobium initiate legume root hair deformation and curling that entrap the bacteria, and allow it to grow inside the plant. In contrast, legumes and non-legumes activate defense responses when inoculated with pathogenic bacteria. One major defense pathway is mediated by salicylic acid (SA). SA is sensed and transduced to downstream defense components by a redox-regulated protein called NPR1. We used Arabidopsis mutants in SA defense pathway to test the role of NPR1 in symbiotic interactions. Inoculation of Sinorhizobium meliloti or purified NF on Medicago truncatula or nim1/npr1 A. thaliana mutants induced root hair deformation and transcription of early and late nodulins. Application of S. meliloti or NF on M. truncatula or A. thaliana roots also induced a strong oxidative burst that lasted much longer than in plants inoculated with pathogenic or mutualistic bacteria. Transient overexpression of NPR1 in M. truncatula suppressed root hair curling, while inhibition of NPR1 expression by RNAi accelerated curling. We show that, while NPR1 has a positive effect on pathogen resistance, it has a negative effect on symbiotic interactions, by inhibiting root hair deformation and nodulin expression. Our results also show that basic plant responses to Rhizobium inoculation are conserved in legumes and non-legumes.

    Full Text Available BACKGROUND: Legumes are unique in their ability to establish symbiotic interaction with rhizobacteria from Rhizobium genus, which provide them with available nitrogen. Nodulation factors (NFs produced by Rhizobium initiate legume root hair deformation and curling that entrap the bacteria, and allow it to grow inside the plant. In contrast, legumes and non-legumes activate defense responses when inoculated with pathogenic bacteria. One major defense pathway is mediated by salicylic acid (SA. SA is sensed and transduced to downstream defense components by a redox-regulated protein called NPR1. METHODOLOGY/PRINCIPAL FINDINGS: We used Arabidopsis mutants in SA defense pathway to test the role of NPR1 in symbiotic interactions. Inoculation of Sinorhizobium meliloti or purified NF on Medicago truncatula or nim1/npr1 A. thaliana mutants induced root hair deformation and transcription of early and late nodulins. Application of S. meliloti or NF on M. truncatula or A. thaliana roots also induced a strong oxidative burst that lasted much longer than in plants inoculated with pathogenic or mutualistic bacteria. Transient overexpression of NPR1 in M. truncatula suppressed root hair curling, while inhibition of NPR1 expression by RNAi accelerated curling. CONCLUSIONS/SIGNIFICANCE: We show that, while NPR1 has a positive effect on pathogen resistance, it has a negative effect on symbiotic interactions, by inhibiting root hair deformation and nodulin expression. Our results also show that basic plant responses to Rhizobium inoculation are conserved in legumes and non-legumes.

  14. Transfer of biologically fixed nitrogen to the non-legume component of mixed pastures

    Pasture ecosystems are extremely diverse, as are the management procedures imposed upon them by the pastoralist. In low input pasture enterprises in marginal areas, legume nitrogen fixation is frequently (but not invariably) crucial to continued productivity. Legumes usually do not dominate a pasture and their role in transferring fixed nitrogen to a non-legume, frequently graminaceous, species is important. Methods for measuring this transfer are critically assessed in terms of their usefulness in realistic pasture environments. Existing techniques all have serious disadvantages in this respect. Isotopic studies of individual processes within the transfer system are described and some new lines of investigation are proposed. The value of isotopic studies in improving pasture management is discussed. (author)

    Soybean flour,chick peas flour and lupines were irradiated at 0,5 and 10 kGy and individually used to replace 5,10 or 15% of wheat flour in shamy bread. The effect of supplementation of wheat flour with these legume flours on the major, chemical composition and nutritional quality of bread was studied. Results indicated that protein, ash and fiber contents of supplemented shamy bread were higher than the control. On the other hand, the amino acids of the shamy wheat bread supplemented irradiated legumes flour, improved the quality (water retention capacity, stailing rate and bread freshness) of bread

    The Partners Clinical Process Improvement Leadership Program provides quality improvement training for clinicians and administrators, utilizing graduates as volunteer peer coaches for mentorship. We sought to understand the factors associated with volunteer coach participation and gain insight into how to improve and sustain this program. Review of coach characteristics from course database and survey of frequent coaches. Out of 516 Partners Clinical Process Improvement Leadership Program graduates from March 2010 to June 2015, 117 (23%) individuals volunteered as coaches. Sixty-one (52%) individuals coached once, 31 (27%) coached twice, and 25 (21%) coached 3 or more times. There were statistically significant associations between coaching and occupation (P = .005), Partners Clinical Process Improvement Leadership Program course taken (P = .001), and course location (P = .007). Administrators were more likely to coach than physicians (odds ratio: 1.75, P = .04). Reasons for volunteering as a coach included further development of skills, desire to stay involved with program, and enjoying mentoring. Reasons for repeated coaching included maintaining quality improvement skills, expanding skills to a wider variety of projects, and networking. A peer graduate volunteer coach model is a viable strategy for interprofessional quality improvement mentorship. Strategies that support repeat coaching and engage clinicians should be promoted to ensure an experienced and diversified group of coaches.

    The Accreditation Council for Graduate Medical Education (ACGME) requires programs to engage annually in program evaluation and improvement. We assessed the value of creating educational competency committees (ECCs) that use successful elements of 2 established processes-institutional special reviews and institutional oversight of annual program evaluations. The ECCs used a template to review programs' annual program evaluations. Results were aggregated into an institutional dashboard. We calculated the costs, sensitivity, specificity, and predictive value by comparing programs required to have a special review with those that had ACGME citations, requests for a progress report, or a data-prompted site visit. We assessed the value for professional development through a participant survey. Thirty-two ECCs involving more than 100 individuals reviewed 237 annual program evaluations over a 3-year period. The ECCs required less time than internal reviews. The ECCs rated 2 to 8 programs (2.4%-9.8%) as "noncompliant." One to 13 programs (1.2%-14.6%) had opportunities for improvement identified. Institutional improvements were recognized using the dashboard. Zero to 13 programs (0%-16%) were required to have special reviews. The sensitivity of the decision to have a special review was 83% to 100%; specificity was 89% to 93%; and negative predictive value was 99% to 100%. The total cost was $280 per program. Of the ECC members, 86% to 95% reported their participation enhanced their professional development, and 60% to 95% believed the ECC benefited their program. Educational competency committees facilitated the identification of institution-wide needs, highlighted innovation and best practices, and enhanced professional development. The cost, sensitivity, specificity, and predictive value indicated good value.

    Consolidated Appropriations Resolution, 2003 Conference Report for the Department of Energy's Biological and Environmental Research (BER) program provided $481,000 for the Legume Genome Initiative at the University of Oklahoma. These funds were used to support our research that is aimed at determining the entire sequence of the gene rich regions of the genome of the legume, Medicago truncatula, by allowing us to obtain a greater degree of finished BAC sequences from the draft sequences we have already obtained through research funded by the Noble Foundation. During the funding period we increased the number of Medicago truncatula BACs with finished (Bermuda standard) sequences from 109 to 359, and the total number of BACs for which we collected sequence data from 584 to 842, 359 of which reached phase 2 (ordered and oriented contigs). We also sequenced a series of pooled BAC clones that cover additional euchromatic (gene rich) genomic regions. This work resulted in 6 refereed publications, see below. Genes whose sequence was determined during this study included multiple members of the plant disease resistance (R-gene) family as well as several genes involved in flavinoid biosynthesis, nitrogen fixation and plant-microbial symbosis. This work also served as a prelude to obtaining NSF funding for the international collaborative effort to complete the entire sequence of the Medicago truncatula genomic euchromatic regions using a BAC based approach.

    2007-06-01

    Full Text Available To improve construction site safety, emphasis has been placed on the implementation of safety programs. In order to successfully gain from safety programs, factors that affect their improvement need to be studied. Sixteen critical success factors of safety programs were identified from safety literature, and these were validated by safety experts. This study was undertaken by surveying 70 respondents from medium- and large-scale construction projects. It explored the importance and the actual status of critical success factors (CSFs. Gap analysis was used to examine the differences between the importance of these CSFs and their actual status. This study found that the most critical problems characterized by the largest gaps were management support, appropriate supervision, sufficient resource allocation, teamwork, and effective enforcement. Raising these priority factors to satisfactory levels would lead to successful safety programs, thereby minimizing accidents.

    Over the past year, the Incorporated Research Institutions for Seismology (IRIS) Education and Public Outreach (EPO) program has undertaken a new effort to increase the rigor with which it evaluates its programs and products. More specifically we sought to make evaluation an integral part of our EPO staff's work, enable staff to demonstrate why we do the activities we do, enhance the impact or our products and programs, and empower staff to be able to make evidence-based claims. The challenges we faced included a modest budget, finding an applicable approach to both new and legacy programs ranging from formal and informal education to public outreach, and implementing the process without overwhelming staff. The Collaborative Impact Analysis Method (IAM; Davis and Scalice, 2015) was selected as it allowed us to combine the EPO staff's knowledge of programs, audiences and content with the expertise of an outside evaluation expert, through consultations and a qualitative rubric assessing the initial state of each product/program's evaluation. Staff then developed action plans to make incremental improvements to the evaluation of programs over time. We have found that this approach promotes the development of staff knowledge and skills regarding evaluation, provides a common language among staff, increases enthusiasm to collect and share data, encourages discussions of evaluative approaches when planning new activities, and improves each program's ability to capture the intended and unintended effects on the behaviors, attitudes, skills, interests, and/or knowledge of users/participants. We will share the initial IAM Scores for products and programs in the EPO portfolio, along with examples of the action plans for several key products and programs, and the impact that implementing those actions plans has had on our evaluations.

    This annual report is in fulfillment of contractual obligations with Bonneville Power Administration (BPA), which is the funding source for the Oregon Department of Fish and Wildlife's (ODFW), Umatilla River Subbasin Fish Habitat Improvement Program (Program). The Program works cooperatively with private landowners to develop long-term restoration agreements, under which, passive and active Habitat Improvement Projects are conducted. Historically, projects have included livestock exclusion fencing (passive restoration) to protect riparian habitats, along with the installation of instream structures (active restoration) to address erosion and improve fish habitat conditions. In recent years, the focus of active restoration has shifted to bioengineering treatments and, more recently, to channel re-design and re-construction aimed at improving fish habitat, through the restoration of stable channel function. This report provides a summary of Program activities for the 2005 calendar year (January 1 through December 31, 2005), within each of the four main project phases, including: (1) Implementation--Pre-Work, (2) Implementation--On Site Development, (3) Operation and Maintenance (O&M), and (4) Monitoring and Evaluation (M&E). This report also summarizes activities associated with Program Administration, Interagency Coordination, and Public Education.

    Comparative genomics is an emerging and powerful approach to achieve crop improvement. Using comparative genomics, information from model plant species can accelerate the discovery of genes responsible for disease and pest resistance, tolerance to plant stresses such as drought, and enhanced nutritional value including production of anti-oxidants and anti-cancer compounds. We demonstrate here how to use the Legume Information System for a comparative genomics study, leveraging genomic information from Medicago truncatula (barrel medic), the model legume, to find candidate genes involved with sudden death syndrome (SDS) in Glycine max (soybean). Specifically, genetic maps, physical maps, and annotated tentative consensus and expressed sequence tag (EST) sequences from G. max and M. truncatula can be compared. In addition, the recently published M. truncatula genomic sequences can be used to identify M. truncatula candidate genes in a genomic region syntenic to a quantitative trait loci region for SDS in soybean. Genomic sequences of candidate genes from M. truncatula can then be used to identify ESTs with sequence similarities from soybean for primer design and cloning of potential soybean disease causing alleles.

    Since 1990, my lab has developed and distributed various DNA clone resources for the legumes. In the first several years, the focus was on members of the tropical genus, Vigna, including the widely cultivated species, mungbean (V. radiata) and cowpea (V. unguiculata). Both of these grain legumes play key roles in agriculture in developing countries of Asia (mungbean) and Africa (cowpea). Moreover, because there is substantial genome conservation among legumes, these genetic resources have also been utilized by a wide range of researchers in other crop species. In 1997, my lab began to focus on the development and distribution of a new generation of DNA clone resources; Bacterial Artificial Chromosomes (BAC). A library of these clones was constructed in soybean (Glycine max) the most important legume species worldwide in terms of economic value. Again, the library has become a valuable resource for the legume research community and has been widely used in studies of legume genomics. (author)

    The Engine Component Improvement (ECI) Program has been initiated in connection with projects designed to reduce the impact of the world-wide energy crisis in the area of aviation. The two parts of the ECI program have the overall objective to identify and quantify the sources and causes of CF6 engine performance deterioration, and to reduce the fuel consumption of CF6 engines through the development and the incorporation of various performance improvement concepts. The CF6 high-bypass turbofan engine was selected as a basis for this effort, since it is expected to be a significant fuel user in commercial revenue service for the next 15 to 20 years. The first part of the ECI program represents the initial step in an effort to achieve a goal of five percent reduction in fuel usage for CF6 engines in the 1979-82 time period. The first performance improvement concept selected is an improved efficiency fan blade. Other improvements are related to a short core exhaust system and an improved high pressure turbine.

    Full Text Available Background: Stroke is a devastating disease with increasing incidence and prevalence due to population aging. Even with the best care, a proportion of patients dies or is left with significant neurological and cognitive disability. Organization of stroke centers markedly improved outcomes worldwide. We initiated a ‘lysis alarm' program in September 2013 at our medical center. Methods: This is a retrospective review of electronic data from patients with acute ischemic stroke before (October 2012-June 2013 and after (October 2013-June 2014 the ‘lysis alarm' program was introduced at our medical center. Results: Prior to the introduction of the stroke program, there were only 19 thrombolysis procedures in 777 acute stroke patients in 9 months, while this figure rose to 32 thrombolysis procedures in 737 acute stroke patients after the initiation of the program. The ‘door-to-needle' time decreased from 88 to 71 min when the two study periods were compared. These changes were associated with decreased stroke mortality in patients receiving thrombolytic treatment (16% prior to the program and 9% during the program. In 2013, there were 1,439 thrombolysis procedures, representing 3.2% of all stroke cases throughout Hungary. After the introduction of the ‘lysis alarm' program, we have reached a 4% thrombolysis rate at our medical center. Conclusions: Our thrombolysis rate is higher than the national average, but still low compared to the rates of Western European countries. We are continuously working to enhance our stroke program. Here, we discuss those components that need to be further refined in order to improve stroke intervention and outcome.

    Global market pressures and increasing competition demands that successful companies establish a continual business improvement program as part of implementing its business strategy. Such programs must be driven by the definition of quality from the customer's perspective. This customer quality focus often requires a change in all aspects of the business including products, services, processes and culture. This paper will describe how Atomic Energy of Canada Limited implemented a Continual Business Improvement Program in their Nuclear Laboratories Business Unit. In particular, to review how the techniques were applied to improve the maintenance process and the status of the project. Customer (internal users of the processes at CRL) feedback has shown repeatedly there is dissatisfaction of the maintenance process. Customers complain about jobs not getting done to schedule or being deferred. A project has been launched with the following goals: to improve the maintenance process customer satisfaction and increase trades wrench time by 30 minutes / trade / day. DMAIC (Define-Measure-Analyze-Improve-Control) methodology was applied to find out the Root Cause(s) of the problem, provide solutions, and implement improvements. The expected Operational Benefits include: Executing work efficiently to quality standards and business performance of the site, improve maintenance efficiencies, reduce cycle time for maintenance process and improve process yield, and improve customer and employee satisfaction.

    In recent years, Lean manufacturing principles have been applied to health care quality improvement efforts to improve wait times. In Ontario, an emergency department (ED) process improvement program based on Lean principles was introduced by the Ministry of Health and Long-Term Care as part of a strategy to reduce ED length of stay (LOS) and to improve patient flow. This article aims to describe the hospital-based teams' experiences during the ED process improvement program implementation and the teams' perceptions of the key factors that influenced the program's success or failure. A qualitative evaluation was conducted based on semistructured interviews with hospital implementation team members, such as team leads, medical leads, and executive sponsors, at 10 purposively selected hospitals in Ontario, Canada. Sites were selected based, in part, on their changes in median ED LOS following the implementation period. A thematic framework approach as used for interviews, and a standard thematic coding framework was developed. Twenty-four interviews were coded and analyzed. The results are organized according to participants' experience and are grouped into four themes that were identified as significantly affecting the implementation experience: local contextual factors, relationship between improvement team and support players, staff engagement, and success and sustainability. The results demonstrate the importance of the context of implementation, establishing strong relationships and communication strategies, and preparing for implementation and sustainability prior to the start of the project. Several key factors were identified as important to the success of the program, such as preparing for implementation, ensuring strong executive support, creation of implementation teams based on the tasks and outcomes of the initiative, and using multiple communication strategies throughout the implementation process. Explicit incorporation of these factors into the

    The purpose of this study was to evaluate any improvement in the quality of abdominal CTs after the utilization of the nationally based accreditation program. Approval was obtained from the Institutional Review Board, and informed consent was waived. We retrospectively analyzed 1,011 outside abdominal CTs, from 2003 to 2007. We evaluated images using a fill-up sheet form of the national accreditation program, and subjectively by grading for the overall CT image quality. CT scans were divided into two categories according to time periods; before and after the implementation of the accreditation program. We compared CT scans between two periods according to parameters pertaining to the evaluation of images. We determined whether there was a correlation between the results of a subjective assessment of the image quality and the evaluation scores of the clinical image. The following parameters were significantly different after the implementation of the accreditation program: identifying data, display parameters, scan length, spatial and contrast resolution, window width and level, optimal contrast enhancement, slice thickness, and total score. The remaining parameters were not significantly different between scans obtained from the two different periods: scan parameters, film quality, and artifacts. After performing the CT accreditation program, the quality of the outside abdominal CTs show marked improvement, especially for the parameters related to the scanning protocol

    We investigated the benefits of a cognitive behavior therapy-based exercise program to reduce the dry eye symptoms of office workers. We recruited 11 office workers with dry eye symptoms, aged 31-64 years, who voluntarily participated in group health guidance at a manufacturing company. Participants learned about the role of physical activity and exercise in enhancing wellness and performed an exercise program at home 3 days per week for 10 weeks. We estimated the indexes of body composition, dry eye symptoms, and psychological distress using the Dry Eye-Related Quality of Life Score and the World Health Organization's Subjective Well-Being Inventory questionnaires pre- and postintervention. The 10-week exercise program and the questionnaires were completed by 48.1% (39 of 81) of the participants. Body composition did not change pre- and postintervention. However, the average of the Dry Eye-Related Quality of Life Score scores in participants with subjective dry eye significantly improved after the intervention. Moreover, the World Health Organization's Subjective Well-Being Inventory positive well-being score tended to increase after the intervention. In this study, we showed that a 10-week exercise program improved subjective dry eye symptoms of healthy office workers. Our study suggests that a cognitive behavior therapy-based exercise program can play an important role in the treatment of patients with dry eye disease.

    Summertime has emerged as a high-risk period for weight gain among low-income minority youth who often experience a lack of resources when not attending school. Structured programming may be an effective means of reducing risk for obesity by improving obesogenic behaviors among these youth. The current multi-method study examined sedentary time, physical activity, and dietary intake among low-income urban minority girls in two contexts: an unstructured summertime setting and in the context of a structured 4-week community-based summer day camp program promoting physical activity. Data were analyzed using paired-sample t tests and repeated-measure analyses of variance with significance at the p programming. All improvements were independent of weight status and age, and African-American participants evidenced greater changes in physical activity during programming. The study concludes that structured, community-based summertime programming may be associated with fewer obesogenic behaviors in low-income urban youth and may be a powerful tool to address disparities in weight gain and obesity among high-risk samples.

    The objective of this work was to formulate a cereals and legume (Phaseolus vulgaris) bar and assess its impact on the glycemic response of healthy individuals, in order to contribute to the healthy food supply beneficial to consumers. A mixture of cereals (corn and oats) and different percentages (20 and 30%) of Phaseolus vulgaris was used to formulate the bar. Additionally, a legume cereal bar without legumes (bar control) was prepared. The bar with 30% of Phaseolus vulgaris was selected through sensory evaluation, being scored with better flavor and texture. This combination of cereals and legumes aminoacid improves complementation and reaches the formulation criteria previously established. Chemical characterization indicated a higher protein content in the bar with 30% of Phaseolus vulgaris (13.55%) relative to the bar control (8.5%). The contents of fat, ash and dietary fiber did not differ between the two bars evaluated. However, the soluble fiber and resistant starch of the selected bar was a 32.05% and 18.67%, respectively, than in the control bar; this may contribute to decreasing the rate of glucose uptake. The selected bar presented a low glycemic index (49) and intermediate glycemic load (12.0) in healthy volunteers, which could lead to a possible reduction in the rate of absorption of glucose into the bloodstream, associated with a carbohydrate content of slow absorption. This bar represents a proposal of a healthy snack for the consumer.

  9. Future prospects for ascochyta blight resistance breeding in cool season food legumes

    2012-02-01

    Full Text Available Legume cultivation is strongly hampered by the occurrence of ascochyta blights. Strategies of control have been developed but only marginal successes have been achieved. Breeding for disease resistance is regarded the most cost efficient method of control. Significant genetic variation for disease resistance exists in most legume crops with numerous germplasm lines maintained, providing an excellent resource for plant breeders. Fast and reliable screening methods have been adjusted to fulfil breeding programmes needs. However, the complex inheritance controlled quantitatively by multiple genes, have been difficult to manipulate. Successful application of biotechnology to ascochyta blight resistance breeding in legume crops will facilitate both a good biological knowledge of the crops and of the mechanisms underlying resistance. The current focus in applied breeding is leveraging biotechnological tools to develop more and better markers to speed up the delivery of improved cultivars to the farmer. To date, however, progress in marker development and delivery of useful markers has been slow. The limited saturation of the genomic regions bearing putative QTLs in legume crops makes difficult to identify the most tightly-linked markers

    During the period 1980-87, the areas sown to grain legumes in Australia increased dramatically, from 0.25 Mha to 1.65 Mha. These increases occurred in the western and southern cereal belts, but not in the north which N continued to be supplied by the mineralization of soil organic matter. Therefore, there was a need to promote the use of N 2 -fixing legumes in the cereal-dominated northern cropping belt. Certain problems had to be addressed before farmers would accept legumes and change established patterns of cropping. Here we describe our efforts to improve N 2 fixation by soybean, common bean and pigeon pea. Selection and breeding for enhanced N 2 fixation of soybean commenced at Tamworth in 1980 after surveys of commercial crops indicated that nodulation was sometimes inadequate, particularly on new land, and that the levels of fixed-N inputs were variable and often low. Similar programmes were established in 1985 (common bean) and 1988 (pigeon bean). Progress was made in increasing N 2 fixation by these legumes towards obtaining economic yields without fertilizer N and contributing organic N for the benefit of subsequent cereal crops

    Legumes are bee-pollinated, but to a different extent. The importance of the plant–pollinator interplay (PPI), in flowering crops such as legumes lies in a combination of the importance of pollination for the production service and breeding strategies, plus the increasing urgency in mitigating the decline of pollinators through the development and implementation of conservation measures. To realize the full potential of the PPI, a multidisciplinary approach is required. This article assembles an international team of genebank managers, geneticists, plant breeders, experts on environmental governance and agro-ecology, and comprises several sections. The contributions in these sections outline both the state of the art of knowledge in the field and the novel aspects under development, and encompass a range of reviews, opinions and perspectives. The first three sections explore the role of PPI in legume breeding strategies. PPI based approaches to crop improvement can make it possible to adapt and re-design breeding strategies to meet both goals of: (1) optimal productivity, based on an efficient use of pollinators, and (2) biodiversity conservation. The next section deals with entomological aspects and focuses on the protection of the “pest control service” and pollinators in legume crops. The final section addresses general approaches to encourage the synergy between food production and pollination services at farmer field level. Two basic approaches are proposed: (a) Farming with Alternative Pollinators and (b) Crop Design System. PMID:27047514

    Full Text Available ABSTRACT OBJECTIVE: To report the initial changes after quality-improvement programs based on STS-database in a Brazilian hospital. METHODS: Since 2011 a Brazilian hospital has joined STS-Database and in 2012 multifaceted actions based on STS reports were implemented aiming reductions in the time of mechanical ventilation and in the intensive care stay and also improvements in evidence-based perioperative therapies among patients who underwent coronary artery bypass graft surgeries. RESULTS: All the 947 patients submitted to coronary artery bypass graft surgeries from July 2011 to June 2014 were analyzed and there was an improvement in all the three target endpoints after the implementation of the quality-improvement program but the reduction in time on mechanical ventilation was not statistically significant after adjusting for prognostic characteristics. CONCLUSION: The initial experience with STS registry in a Brazilian hospital was associated with improvement in most of targeted quality-indicators.

    Full Text Available Abstract Background Medicago truncatula is a model legume whose genome is currently being sequenced by an international consortium. Abiotic stresses such as salt stress limit plant growth and crop productivity, including those of legumes. We anticipate that studies on M. truncatula will shed light on other economically important legumes across the world. Here, we report the development of a database called MtED that contains gene expression profiles of the roots of M. truncatula based on time-course salt stress experiments using the Affymetrix Medicago GeneChip. Our hope is that MtED will provide information to assist in improving abiotic stress resistance in legumes. Description The results of our microarray experiment with roots of M. truncatula under 180 mM sodium chloride were deposited in the MtED database. Additionally, sequence and annotation information regarding microarray probe sets were included. MtED provides functional category analysis based on Gene and GeneBins Ontology, and other Web-based tools for querying and retrieving query results, browsing pathways and transcription factor families, showing metabolic maps, and comparing and visualizing expression profiles. Utilities like mapping probe sets to genome of M. truncatula and In-Silico PCR were implemented by BLAT software suite, which were also available through MtED database. Conclusion MtED was built in the PHP script language and as a MySQL relational database system on a Linux server. It has an integrated Web interface, which facilitates ready examination and interpretation of the results of microarray experiments. It is intended to help in selecting gene markers to improve abiotic stress resistance in legumes. MtED is available at http://bioinformatics.cau.edu.cn/MtED/.

    Full Text Available Christie van Diggele,1 Annette Burgess,2 Craig Mellis21The University of Sydney, Sydney, NSW, Australia; 2Sydney Medical School – Central, The University of Sydney, Sydney, NSW, AustraliaIntroduction: Skills in peer teaching, assessment, and feedback are increasingly documented internationally as required graduate attributes in medicine. Yet these skills are rarely taught in medical schools. We sought to design and deliver a short but effective teacher training (TT program for medical students that could be easily integrated into the professional development curriculum. This study sought to evaluate such a pilot program, based on student perception.Methods: The study took place at a major metropolitan teaching hospital, where 38 medical students were invited to attend a voluntary, newly designed four-module TT program. In total, 23/38 (61% of invited students attended. Mixed methods were used for evaluation. Questionnaires were completed by 21/23 (91% of students, and 6/23 (26% of students participated in a focus group.Results: Students reported that as a result of the program they felt more confident to facilitate small group teaching activities and to provide feedback to peers using the suggested frameworks. Students would like the program to contain more in-depth educational theory and to allow a more time for small group learning activities. They would also like to see opportunities for participation across all clinical schools.Conclusion: The TT program was successful in increasing student awareness of educational theory and practice, thereby improving their confidence in teaching and assessing their peers and making them feel better prepared for their careers as medical practitioners. Key improvements to the program are needed in terms of more in-depth theory and more time spent on small group learning. This might be achieved by complementing the course with e-learning.Keywords: teacher training, medical students, peer teaching, peer

    There is scarce evidence of organization-wide and sustained impact of quality improvement (QI) programs in health care. For 20 years, the Jönköping County Council's (Sweden) ambitious program has attracted attention from practitioners and researchers alike. This is a follow-up case of a 2006 study of Jönköping's improvement program, triangulating data from 20 semi-structured interviews, observation and secondary analysis of internal performance data. In 2010, clinical outcomes had clearly improved in 2 departments (pediatrics, intensive care), while process improvements were evident in many departments. In an overall index of the 20 Swedish county councils' performance, Jönköping had improved its ranking since 2006 to lead in 2010. Five key issues shaped Jönköping's improvement program since 2006: a rigorously managed succession of chief executive officer; adept management of a changing external context; clear strategic direction relating to integration; a broadened conceptualization of "quality" (incorporating clinical effectiveness, patient safety, and patient experience); and continuing investment in QI education and research. Physician involvement in formal QI initiatives had increased since 2006 but remained a challenge in 2010. A new clinical information system was being deployed but had not yet met expectations. This study suggests that ambitious approaches can carry health care organizations beyond the sustainability threshold.

    Full Text Available In 2005-2007 growing season, few varieties of field bean, high protein pea and white lupin were compared in an organic farm of Central Italy (Mugello area, Tuscany, to evaluate their agronomic performance in terms of grain yield, nutritional quality and competitive ability against weeds. The experiment was performed under rain-fed conditions. Furthermore, grain legumes features were compared between two different sowing seasons (autumnal vs late-winter for two years, in order to get information on the best time of sowing of these species, and the stability of yields of different genotypes in those climatic and soil conditions. These legumes could be an alternative protein source to external soybean, a high-risk alimentary source of genetically modified organisms, in the organic livestock sector. The main findings indicate that higher yields in grain and crude protein were obtained with the pea species and in particular with cultivars Hardy (4.0 t/ha grain yield; 626 kg/ha crude protein yield and Classic (3.1 t/ha grain yield; 557 kg/ha crude protein yield; followed by field bean cv. Chiaro di Torre Lama (2.9 t/ha grain yield; 624 kg/ha crude protein yield and cv. Vesuvio (2.5 t/ha grain yield; 549 kg/ha crude protein yield. Furthermore the field bean is interesting for the stability of yield in both years despite climatic conditions rather different. The white lupin has showed the lower yield but the best values of grain quality, with higher values in lupin Multitalia for dry matter, crude protein and ether extract and in lupin Luxe also for crude fibre, respect to the other legumes analysed. Among lupin varieties, lupin Multitalia showed the best yield results for the pedo-climatic conditions of Mugello area (0.9 t/ha lupin Multitalia; 0.2 t/ha lupin Luxe. The total yield of organic grain legumes, in the experimental site, is resulted higher with an autumnal seeding respect to the late-winter seeding (2.8 t/ha vs 1.9 t/ha.

    The Clinical Learning Environment Review focuses on the responsibility of the sponsoring institution for quality and patient safety. Very little information is known regarding the status of quality improvement (QI) education during otolaryngology training. The purpose of this survey is to evaluate the extent of resident and faculty participation in QI and identify opportunities for both resident curriculum and faculty development. Cross-sectional survey A 15-item survey was distributed to all 106 otolaryngology program directors. The survey was developed after an informal review of the literature regarding education in QI and patient safety. Questions were directed at the format and content of the QI curriculum, as well as barriers to implementation. There was a 39% response rate. Ninety percent of responding program directors considered education in QI important or very important to a resident's future success. Only 23% of responding programs contained an educational curriculum in QI, and only 33% monitored residents' individual outcome measures. Barriers to implementation of a QI program included inadequate number of faculty with expertise in QI (75%) and competing resident educational demands (90%). Every program director considered morbidity and mortality conferences as an integral component in QI education. Program directors recognize the importance of QI in otolaryngology practice. Unfortunately, this survey identifies a distinct lack of resources in support of these educational goals. The results highlight the need to generate a comprehensive and stepwise approach to QI for faculty development and resident instruction. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

  20. Recommendations for improvements to program and project management

    Energy Technology Data Exchange (ETDEWEB)

    1994-01-01

    Oak Ridge National Laboratory (ORNL) has operated with a balanced matrix organization for over sixteen years. Much of the work at the Laboratory is accomplished with good customer satisfaction through programs, projects, and matrix management. During the past several years concerns about program and project management at ORNL have been expressed by both the Department of Energy and ORNL staff. In May 1993 the ORNL Division/Program/Office Directors Caucus chartered a ``fox team`` to identity and to recommend improvements to matrix management that would lead to resolution of these concerns. Nine experienced ORNL staff members served on this Matrix Management Upgrade Solutions Team (MMUST). The MMUST adopted a four-phase approach in which they first gathered information and then developed and proposed recommended actions. In the fourth phase the team was available to support implementation of the recommendations. They began work in June 1993, gathering and evaluating information in biweekly meetings for six months. Recommendations developed in October and November 1993 were presented to ORNL management in December. The MMUST issued three principal recommendations based on their evaluation of the information gathered. They are: Renew and enhance the ORNL management commitment to matrix management, program managers, and project managers; Implement actions to ensure career path parity between the program/project manager family of positions and the technical line manager family of positions across all directorates and divisions; and Clarify and document program/project manager roles, responsibilities, and authorities.

  1. Student Feedback of Career Development Workshops for Program Improvement

    2016-12-01

    A number of techniques are employed each year to evaluate the effectiveness of and to identify opportunities for improvement in the Laboratory for Atmospheric Research (LAR) REU program at Washington State University. For example, information gathered from pre-/post-surveys and pre-/post-interviews provides information regarding students' perceptions and levels of experience with the scientific process, career and academic goals, and motivation for joining the REU program. Poster session rubrics assess students' abilities to summarize their experiences in a professional setting. Alumni surveys gauge former participants' perceptions of the REU experience. One seemingly simple and highly useful, but often less documented, component of the evaluation process for program improvement is the use of workshop feedback forms. Weekly workshops are designed to provide students with enhanced knowledge and skills in the area of atmospheric chemistry as well as research design skills, academic and career guidance, and presentation skills. According to previous years' evaluation reports, workshops are largely beneficial to students for learning new skills. Yet, students suggest a number of recommendations that may benefit any REU program, such as: providing slides beforehand to provide a framework for the upcoming workshop, having instructors speak in more student-friendly language, covering higher-level topics, and including more hands-on, instructor-guided practice during the workshops. Thus, workshop feedback forms provide meaningful feedback to increase learning outcomes and enhance the REU student experience. This presentation will offer ideas gathered from over five years of workshop feedback forms that, while somewhat specific to workshops offered for the LAR REU, can offer faculty and PIs insight into the student experience, enhancing their ability to improve programming and achieve greater learning outcomes.

    Grain legumes are a cost-effective alternative for the animal protein in improving the diets of the poor in South-East Asia and Africa. Legumes, through symbiotic nitrogen fixation, meet a major part of their own N demand and partially benefit the following crops of the system by enriching soil. In realization of this sustainability advantage and to promote pulse production, United Nations had declared 2016 as the "International Year of pulses". Grain legumes are frequently subjected to both abiotic and biotic stresses resulting in severe yield losses. Global yields of legumes have been stagnant for the past five decades in spite of adopting various conventional and molecular breeding approaches. Furthermore, the increasing costs and negative effects of pesticides and fertilizers for crop production necessitate the use of biological options of crop production and protection. The use of plant growth-promoting (PGP) bacteria for improving soil and plant health has become one of the attractive strategies for developing sustainable agricultural systems due to their eco-friendliness, low production cost and minimizing consumption of non-renewable resources. This review emphasizes on how the PGP actinobacteria and their metabolites can be used effectively in enhancing the yield and controlling the pests and pathogens of grain legumes.

    José Carlos Batista Dubeux Junior

    Full Text Available ABSTRACT Tree legumes are an underexploited resource in warm-climate silvopastures. Perceived benefits of tree legumes include provisioning (browse/mast, timber, fuel, human food, natural medicines, and ornamentals, regulating (C sequestration, greenhouse gas mitigation, soil erosion control and riparian buffers, shade, windbreaks, and habitat for pollinators, supporting (biological N2-fixation, nutrient cycling, soil fertility and soil health, photosynthesis, and primary productivity, and cultural ecosystem services. Tree legumes, however, have not been assessed to the same extent as herbaceous legumes. Once tree legumes are established, they are often more persistent than most herbaceous legumes. There are limitations for extended research with tree legume silvopastures, but extensive research has been done in Africa and Australia and recent efforts have been reported in South America. Economic benefits must be demonstrated to land managers to increase adoption. These benefits are apparent in the research and successes already available, but more long-term research, including the livestock component is necessary. Other factors that reduce adoption include paucity of domesticated germplasm, lag in research/technology, challenges of multipurpose trees and management complexity, challenges to mechanization, dangers of invasive weeds, and social and cultural barriers. In the current scenario of climate change and the need to increase food security, tree legumes are a key component for the sustainable intensification of livestock systems in warm-climate regions.

    There is an increasing interest toward the use of legumes in food industry, mainly due to the quality of their protein fraction. Many legumes are cultivated and consumed around the world, but few data is available regarding the chemical or technological characteristics, and especially on their suitability to be fermented. Nevertheless, sourdough fermentation with selected lactic acid bacteria has been recognized as the most efficient tool to improve some nutritional and functional properties. This study investigated the presence of lunasin-like polypeptides in nineteen traditional Italian legumes, exploiting the potential of the fermentation with selected lactic acid bacteria to increase the native concentration. An integrated approach based on chemical, immunological and ex vivo (human adenocarcinoma Caco-2 cell cultures) analyses was used to show the physiological potential of the lunasin-like polypeptides. Italian legume varieties, belonging to Phaseulus vulgaris, Cicer arietinum, Lathyrus sativus, Lens culinaris and Pisum sativum species, were milled and flours were chemically characterized and subjected to sourdough fermentation with selected Lactobacillus plantarum C48 and Lactobacillus brevis AM7, expressing different peptidase activities. Extracts from legume doughs (unfermented) and sourdoughs were subjected to western blot analysis, using an anti-lunasin primary antibody. Despite the absence of lunasin, different immunoreactive polypeptide bands were found. The number and the intensity of lunasin-like polypeptides increased during sourdough fermentation, as the consequence of the proteolysis of the native proteins carried out by the selected lactic acid bacteria. A marked inhibitory effect on the proliferation of human adenocarcinoma Caco-2 cells was observed using extracts from legume sourdoughs. In particular, sourdoughs from Fagiolo di Lamon, Cece dell'Alta Valle di Misa, and Pisello riccio di Sannicola flours were the most active, showing a decrease

    Biological nitrogen fixation (BNF) by crop legumes reduces demand for industrial nitrogen fixation (INF). Nonetheless, rates of BNF in agriculture remain low, with strong negative feedback to BNF from reactive soil nitrogen (N) and drought. We show that breeding for yield has resulted in strong relationships between photosynthesis and leaf N in non-leguminous crops, whereas grain legumes show strong relations between leaf N and water use efficiency (WUE). We contrast these understandings with other studies that draw attention to the water costs of grain legume crops, and their potential for polluting the biosphere with N. We propose that breeding grain legumes for reduced stomatal conductance can increase WUE without compromising production or BNF. Legume crops remain a better bet than relying on INF.

    Televisions (TVs) account for a significant portion of residential electricity consumption and global TV shipments are expected to continue to increase. We assess the market trends in the energy efficiency of TVs that are likely to occur without any additional policy intervention and estimate that TV efficiency will likely improve by over 60% by 2015 with savings potential of 45 terawatt-hours [TW h] per year in 2015, compared to today’s technology. We discuss various energy-efficiency improvement options and evaluate the cost effectiveness of three of them. At least one of these options improves efficiency by at least 20% cost effectively beyond ongoing market trends. We provide insights for policies and programs that can be used to accelerate the adoption of efficient technologies to further capture global energy savings potential from TVs which we estimate to be up to 23 TW h per year in 2015. - Highlights: • We analyze the impact of the recent TV market transition on TV energy consumption. • We review TV technology options that could be realized in the near future. • We assess the cost-effectiveness of selected energy-efficiency improvement options. • We estimate global electricity savings potential in selected scenarios. • We discuss possible directions of market transformation programs

Materials and methods: We recruited 11 office workers with dry eye symptoms, aged 31–64 years, who voluntarily participated in group health guidance at a manufacturing company. Participants learned about the role of physical activity and exercise in enhancing wellness and performed an exercise program at home 3 days per week for 10 weeks. We estimated the indexes of body composition, dry eye symptoms, and psychological distress using the Dry Eye-Related Quality of Life Score and the World Health Organization’s Subjective Well-Being Inventory questionnaires pre- and postintervention. Results: The 10-week exercise program and the questionnaires were completed by 48.1% (39 of 81 of the participants. Body composition did not change pre- and postintervention. However, the average of the Dry Eye-Related Quality of Life Score scores in participants with subjective dry eye significantly improved after the intervention. Moreover, the World Health Organization’s Subjective Well-Being Inventory positive well-being score tended to increase after the intervention. Conclusion: In this study, we showed that a 10-week exercise program improved subjective dry eye symptoms of healthy office workers. Our study suggests that a cognitive behavior therapy-based exercise program can play an important role in the treatment of patients with dry eye disease.

    Since the 1970s, the federal government has spearheaded major national education programs to reduce the burden of chronic diseases in the United States. These prevention and disease management programs communicate critical information to the public, those affected by the disease, and health care providers. The National Diabetes Education Program (NDEP), the leading federal program on diabetes sponsored by the National Institutes of Health (NIH) and the Centers for Disease Control and Prevention (CDC), uses primary and secondary quantitative data and qualitative audience research to guide program planning and evaluation. Since 2006, the NDEP has filled the gaps in existing quantitative data sources by conducting its own population-based survey, the NDEP National Diabetes Survey (NNDS). The NNDS is conducted every 2–3 years and tracks changes in knowledge, attitudes and practice indicators in key target audiences. This article describes how the NDEP has used the NNDS as a key component of its evaluation framework and how it applies the survey results for strategic planning and program improvement. The NDEP's use of the NNDS illustrates how a program evaluation framework that includes periodic population-based surveys can serve as an evaluation model for similar national health education programs.

    The U.S. Nuclear Regulatory Commission (NRC) identifies (by its assessment of plant operation) certain issues involving public health and safety, the common defense and security, or the environment that could affect multiple entities under NRC jurisdiction. The Generic Issues Program (GIP) addresses the resolution of these Generic Issues (GIs). The resolution of these issues may involve new or revised rules, new or revised guidance, or revised interpretation of rules or guidance that affect nuclear power plant licensees, nuclear material certificate holders, or holders of other regulatory approvals. U.S. NRC provides information related to the past and ongoing GIP activities to the general public by the use of three main resources, namely NUREG-0933, 'Resolution of Generic Safety Issues, ' Generic Issues Management Control System (GIMCS), and GIP public web page. GIP information resources provide information such as historical information on resolved GIs, current status of the open GIs, policy documents, program procedures, GIP annual and quarterly reports and the process to contact GIP and propose a GI This paper provides an overview of the GIP and several examples of safety improvements resulting from the resolution of GIs. In addition, the paper provides a brief discussion of a few recent GIs to illustrate how the program functions to improve safety. (authors)

    Anemia is common in hemodialysis patients, and improvement in anemia management is possible with the implementation of continuous quality improvement (CQI) programs. The aim of this study is to improve anemia management in chronic hemodialysis patients using CQI. Ninety hemodialysis patients in our single center were enrolled in the study. The patients were followed up from January 2004 to October 2005. The CQI team-oriented approach was driven by a process called the 'FOCUS-PDCA cycle plan' (find, organize, clarify, uncover, start, plan, do, check and act). Hemoglobin (Hb), serum ferritin and transferrin saturation were monitored periodically. By implementation of the CQI program, the proportion of patients with Hb >or=110 g/l increased from 42.2 to 60.0% (p method in the management of anemia in hemodialysis patients. Copyright 2006 S.

    Full Text Available Cereals and legumes are important part of dietaries and contribute substantially to nutrient intake of human beings. They are significant source of energy, protein, dietary fiber, vitamins, minerals, and phytochemicals. Primary processing of cereals and legumes is an essential component of their preparation before use. For some grains, dehusking is an essential step, whereas for others, it could be milling the grain into flour. Grains are subjected to certain processing treatments to impart special characteristics and improve organoleptic properties such as expanded cereals. All these treatments result in alteration of their nutritional quality which could either be reduction in nutrients, phytochemicals and antinutrients or an improvement in digestibility or availability of nutrients. It is important to understand these changes occurring in grain nutritional quality on account of pre-processing treatments to select appropriate techniques to obtain maximum nutritional and health benefits. This review attempts to throw light on nutritional alterations occurring in grains due to pre-processing treatments.

    A primary objective of the multilaboratory program is to prepare an updated and improved set of dosimetry, damage correlation, and the associated reactor analysis ASTM standards for LWR-PV irradiation surveillance programs. Supporting this objective are a series of analytical and experimental validation and calibration studies in Benchmark Neutron Fields, reactor Test Regions, and operating power reactor Surveillance Positions. These studies will establish and certify the precision and accuracy of the measurement and predictive methods which are recommended for use in these standards. Consistent and accurate measurement and data analysis techniques and methods, therefore, will have been developed and validated along with guidelines for required neutron field calculations that are used to (1) correlate changes in material properties with the characteristics of the neutron radiation field and (2) predict pressure vessel steel toughness and embrittlement from power reactor surveillance data

    The vitrification of high-level liquid waste produced from nuclear fuel reprocessing has been carried out industrially for over 25 years by AREVA/COGEMA, with two main objectives: containment of the long lived fission products and reduction of the final volume of waste. At the 'La Hague' plant, in the 'R7' and 'T7' facilities, vitrified waste is obtained by first evaporating and calcining the nitric acid feed solution-containing fission products in calciners. The product-named calcinate- is then fed together with glass frit into induction-heated metallic melters to produce the so-called R7/T7 glass, well known for its excellent containment properties. Both facilities are equipped with three processing lines. In the near future the increase of the fuel burn-up will influence the amount of fission product solutions to be processed at R7/T7. As a consequence, in order to prepare these changes, it is necessary to feed the calciner at higher flow-rates. Consistent and medium-term R and D programs led by CEA (French Atomic Energy Commission, the AREVA/COGEMA's R and D and R and T provider), AREVA/COGEMA (Industrial Operator) and AREVA/SGN (AREVA/COGEMA's Engineering), and associated to the industrial feed back of AREVA/COGEMA operations, have allowed continuous improvement of the process since 1998: - The efficiency and limitation of the equipment have been studied and solutions for technological improvements have been proposed whenever necessary, - The increase of the feeding flow-rate has been implemented on the improved CEA test rig (so called PEV, Evolutional Prototype of Vitrification) and adapted by AREVA/SGN for the La Hague plant using their modeling studies; the results obtained during this test confirmed the technological and industrial feasibility of the improvements achieved, - After all necessary improved equipments have been implemented in R7/T7 facilities, and a specific campaign has been performed on the R7 facility by AREVA/COGEMA.

    Full Text Available Root parasitic weeds are a major limiting production factor in a number of crops, and control is difficult. Genetic resistance and chemical control lead the fight, but without unequivocal success. Models that help to describe and even predict the evolution of parasitism underground are a valuable tool for herbicide applications, and even could help in breeding programs. Legumes are heavily affected by Orobanche crenata (crenate broomrape in the Mediterranean basin. This work presents a descriptive model based on thermal time and correlating growing day-degrees (GDD with the different developmental stages of the parasite. The model was developed in three different legume crops (faba bean, grass pea and lentil attacked by crenate broomrape. The developmental stages of the parasite strongly correlated with the GDD and differences were found depending on the host crop.

    The aim was to evaluate pre-post quality of care measures among super-utilizer patients enrolled in the Enhanced Care Program (ECP), a primary care intensive care program. A pre-post analysis of metrics of quality of care for diabetes, hypertension, cancer screenings, and connection to mental health care for participants in the ECP was conducted for patients enrolled in ECP for 6 or more months. Patients enrolled in ECP showed statistically significant improvements in hemoglobin A1c, retinal exams, blood pressure measurements, and screenings for colon cancer, and trends toward improvement in diabetic foot exams and screenings for cervical and breast cancer. There was a significant increase in connecting patients to mental health care. This study shows that super-utilizer patients enrolled in the ECP had significant improvements in quality metrics from those prior to enrollment in ECP.

    Grain legumes are an important source of nutrition and income for billions of consumers and farmers around the world. However, the low productivity of new legume varieties, due to the limited genetic diversity available for legume breeding programmes and poor policymaker support, combined with an increasingly unpredictable global climate is resulting in a large gap between current yields and the increasing demand for legumes as food. Hence, there is a need for novel approaches to develop new high-yielding legume cultivars that are able to cope with a range of environmental stressors. Next-generation technologies are providing the tools that could enable the more rapid and cost-effective genomic and transcriptomic studies for most major crops, allowing the identification of key functional and regulatory genes involved in abiotic stress resistance. In this review, we provide an overview of the recent achievements regarding abiotic stress resistance in a wide range of legume crops and highlight the transcriptomic and miRNA approaches that have been used. In addition, we critically evaluate the availability and importance of legume genetic resources with desirable abiotic stress resistance traits. © 2018 John Wiley & Sons Ltd.

    Full Text Available Cognitive training has been shown to improve executive functions in middle childhood and adulthood. However, fewer studies have targeted the preschool years – a time when executive functions undergo rapid development. The present study tested the effects of a short four session executive function training program in 54 four-year-olds. The training group significantly improved their working memory from pre-training relative to an active control group. Notably, this effect extended to a task sharing few surface features with the trained tasks, and continued to be apparent three months later. In addition, the benefits of training extended to a measure of mathematical reasoning three months later, indicating that training executive functions during the preschool years has the potential to convey benefits that are both long-lasting and wide-ranging.

    Semiannually, the National Surgical Quality Improvement Program (NSQIP) provides its participating sites with observed-to-expected (O/E) ratios for 30-day postoperative mortality and morbidity. At each reporting period, there is typically a small group of hospitals with statistically significantly high O/E ratios, meaning that their patients have experienced more adverse events than would be expected on the basis of the population characteristics. An important issue is to determine which actions a surgical service should take in the presence of a high O/E ratio. This article reviews case studies of how some of the Department of Veterans Affairs and private-sector NSQIP participating sites used the clinically rich NSQIP database for local quality improvement efforts. Data on postoperative adverse events before and after these local quality improvement efforts are presented. After local quality improvement efforts, wound complication rates were reduced at the Salt Lake City Veterans Affairs medical center by 47%, surgical site infections in patients undergoing intraabdominal surgery were reduced at the University of Virginia by 36%, and urinary tract infections in vascular patients were reduced at the Massachusetts General Hospital by 74%. At some sites participating in the NSQIP, notably the Massachusetts General Hospital and the University of Virginia, the NSQIP has served as the basis for surgical service-wide outcomes research and quality improvement programs. The NSQIP not only provides participating sites with risk-adjusted surgical mortality and morbidity outcomes semiannually, but the clinically rich NSQIP database can also serve as a catalyst for local quality improvement programs to significantly reduce postoperative adverse event rates.

    Public Service Electric and Gas (PSE and G) Company operates three commercial nuclear power plants in southern New Jersey. The three plants are of different designs and vintages (two pressurized water reactors licensed in 1976 and 1980 and one boiling water reactor licensed in 1986). As the industry recognized the need to develop design basis programs, PSE and G also realized the need after a voluntary 52-day shutdown of one unit because of electrical design basis problems. In its drive to be a premier electric utility, PSE and G has been aggressively active in developing design basis documents (DBDs) with supporting projects and refined uses to obtain the expected value and see the return on investment. Progress on Salem is nearly 75% complete, while Hope Creek is 20% complete. To data, PSE and G has experienced success in the use of DBDs in areas such as development of plant modifications, development of the reliability-centered maintenance program, procedure upgrades, improved document retrieval, resolution of regulatory issues, and training. The paper examines the design basis development process, supporting projects, and expected improvements in plant operations as a result of these efforts

    HIV programs have provided a major impetus for investments in surveillance data, with 5-10% of HIV program budgets recommended to support data. However there are questions concerning the sustainability of these investments. The Sustainable Development Goals have consolidated health into one goal and communicable diseases into one target (Target 3.3). Sustainable Development Goals now introduce targets focused specifically on data (Targets 17.18 and 17.19). Data are seen as one of the three systemic issues (in Goal 17) for implementing Sustainable Development Goals, alongside policies and partnerships. This paper reviews the surveillance priorities in the context of the Sustainable Development Goals and highlights the shift from periodic measurement towards sustainable disaggregated, real-time, case, and patient data, which are used routinely to improve programs. Finally, the key directions in developing person-centered monitoring systems are assessed with country examples. The directions contribute to the Sustainable Development Goal focus on people-centered development applied to data. ©Daniel Low-Beer, Mary Mahy, Francoise Renaud, Txema Calleja.

    Full Text Available The present paper explains the stages of clothing style improvement by using computer graphics programs. Ovidiu Stan, a student in the Department of Textiles and Leatherworking and Industrial Management, under our guidance, did research at the Ethnographic Museum of Transylvania in Cluj Napoca, where he selected a folk pattern specific to Transylvania area, reinterpreted it and digitized it in the vector graphics program CorelDRAW. This program allows the shape and size of drawings to be modified, and offers a vast chromatic palette which allows us to style the drawings. The pattern was printed on the T-shirt with an Azon Tex Pro printer, which can replace screen-printing or thermal transfer. The printing system is high-speed and very high quality, and the printed patterns can be unique, highly resistent to wear and washing. After the digitization stage, the next stage was to embroider the pattern on the T-shirt with the Happy embroidery machine. The embroidered pattern was designed by using the BERNINA Embroidery Software Designer Plus software. This embroidery software offers the freedom to design and edit elegant monograms, and complete freedom of creative design. All the projects completed with this software can bear their own distinct, individual mark, as an original work of art.

  1. Program planning for future improvement in managing ORNL's radioactive wastes

    International Nuclear Information System (INIS)

    1982-01-01

    This report is intended to serve as a reference document and guide in developing the long-term improvements section of ORNL's radioactive waste management plan. The report reviews ORNL's operations and future program needs in terms of currently applicable DOE regulations and also in terms of regulations and accepted practices of the commerical sector of the nuclear power industry so that the impact of potential future adoption of these regulations and standards on ORNL's operations can be fully evaluated. The principal conclusion reached after reviewing ORNL's waste management operations is that these operations are currently being conducted in a manner that does not endanger the health or safety of workers or the general public and that does not have an adverse effect on the environment. Although nineteen specific problem areas have been identified all of these problems can be attributed to one of the following: a) the legacy of past practices; b) gradual deterioration of systems which have reached (or are near to reaching) the end of their reasonable design lives; and c) potential changes in regulations applicable to ORNL. All of the programs designed to improve or correct these problem areas could be accomplished within a four year period. However, given current limitations on manpower and capital, these programs would more likely be spread out over a five to ten year period of time if they were all to be undertaken. The cost of undertaking all of these projects concurrently is estimated to be between 60 and 100 million dollars. Due to the many unknowns and uncertainties associated with the problem areas, actual total costs for specific projects could vary from those presented in this report by as much as 300 percent

    Full Text Available Cattle and maize play important roles in the dryland faming systems in Timor island of East Nusa Tenggara province, contributing to the farmers’ income, social status, and the regional food security and sources of income. However, the productivity of both commodities is low because of several problems. Lack of feed supply and management knowledge has contributed to the low cattle productivity, while lack of cultivation knowledge and the use of low productivity local maize have caused low productivity in maize. Farmers in Timor in general do not apply fertilizer to their maize plants, although lack of nitrogen (N is evident in many of their maize fields. There is potential to improve the available N in the soils through the incorporation of herbaceous legumes, which can supply the nutrient to the soil as well as providing good quality fodders for the cattle. Among the introduced herbaceous legumes tested, Clitoria ternatea (butterfly pea has shown good performances to be used as an alternative herbaceous legume in the farming system for improving soil fertility and maize production as well as to provide good quality fordder for the cattle.

Therefore, the objectives of this study were to develop and suggest an adaptive technology for cultivation of legumes taking into account existing methodologies for environmentallyfriendly production in the dry steppe zone of Akmola region, Northern Kazakhstan. In order to achieve the objectives, the study focused on determination of a complex impact of combination of agroecological conditions (incl. agro- climatic, content of selected heavy metals such as Cu and Zn in soil, weed pressure, etc., contrasting soil cultivation technology (i.e. traditional vs zero- tillage, nutrient inputs (fertilizers, legume stimulators and pesticides on growth and productivity of selected legume crops (peas and chickpeas. The overall agroecological and growing conditions were suitable for producing economically- important legume crops (i.e. pea and chickpea, despite the temperature fluctiations and soil moisture shortage. Despite the very low content of N and P in the upper soil layer, the Cu and Zn content was within the Maximum Permissible Limits (MPL for Kazakhstan, with a low anticipated negative effect on target legume growth. The least number of weeds was recorded by the variant with application of biological preparation Respecta. The targeted legumes were better developed during the growing season under the traditional technology compared to zero- tillage technology, i.e. germination and seed viability, which might be attributed to better utilisation of soil air and improved soil porosity of the soil layer of 0- 20 cm when using traditional technology. Combinations of mineral fertilizer CaSO4 + 2H2O5 with the innoculation promoter Rizotorfin, and Izagry Phosphorus with Rizotorfin may be recommended to farmers. The application of

    A large amount of energy is utilized by legume nodules for the fixation of nitrogen and assimilation of fixed nitrogen (ammonia) into organic compounds. The source of energy is provided in the form of photosynthates by the host plant. Phosphoenol pyruvate carboxylase (PEPC) enzyme, which is responsible for carbon dioxide fixation in C4 and crassulacean acid metabolism plants, has also been found to play an important role in carbon metabolism in legume root nodule. PEPC-mediated CO2 fixation in nodules results in the synthesis of C4 dicarboxylic acids, viz. aspartate, malate, fumarate etc. which can be transported into bacteroids with the intervention of dicarboxylate transporter (DCT) protein. PEPC has been purified from the root nodules of few legume species. Information on the relationship between nitrogen fixation and carbon metabolism through PEPC in leguminous plants is scanty and incoherent. This review summarizes the various aspects of carbon and nitrogen metabolism in legume root nodules.

    Background: The European Practice Assessment program provides feedback and outreach visits to primary care practices to facilitate quality improvement in five domains (infrastructure, people, information, finance, and quality and safety). We examined the effectiveness of this program in improving management in primary care practices in Germany, with a focus on the domain of quality and safety. Methods: In a before–after study, 102 primary care practices completed a practice assessment using the European Practice Assessment instrument at baseline and three years later (intervention group). A comparative group of 102 practices was included that completed their first assessment using this instrument at the time of the intervention group’s second assessment. Mean scores were based on the proportion of indicators for which a positive response was achieved by all of the practices, on a scale of 0 to 100. Results: We found significant improvements in all domains between the first and second assessments in the intervention group. In the domain of quality and safety, improvements in scores (mean scores were based on the proportion of indicators for which a positive response was achieved by all of the practices, on a scale of 0 to 100) were observed in the following dimensions: complaint management (from a mean score of 51.2 at first assessment to 80.7 at second assessment); analysis of critical incidents (from 79.1 to 89.6); and quality development, quality policy (from 40.7 to 55.6). Overall scores at the time of the second assessment were significantly higher in the intervention group than in the comparative group. Interpretation: Primary care practices that completed the European Practice Assessment instrument twice over a three-year period showed improvements in practice management. Our findings show the value of the quality-improvement cycle in the context of practice assessment and the use of established organizational standards for practice management with the

    Full Text Available Gradual reduction of legumes in mixed tropical pastures requires periodic oversowing. Exploiting the carrying capacity of grass for an extra year after the disappearance of legumes can be economically advantageous to the farmer. This study aimed to evaluate the productivity of Xaraés palisadegrass (Brachiaria brizantha pastures in response to its historical association with stylo (Stylosanthes guianensis under two canopy heights to determine whether different grazing management conditions affect the defoliation pattern left by grazing animals. The split-plot experimental design was used, with the historical botanical composition (HBC (24, 34, 45 and 52 % legume composition corresponding to the main plots and the canopy frequency of defoliation determined at heights of 30 and 45 cm for Xaraés palisadegrass corresponding to the subplots with two replicates (500 m2 grazed by Tabapuã cows. Pastures with over 34 % stylo in the botanical composition remained productive for one year after legume disappearance, accumulating more than 8 mg ha−1 of forage per year. Xaraés palisadegrass pastures at a height of 30 cm provided better canopy structure, with 64 % less stem production and 43 % less dead material. The 30-cm pre-grazing canopy height provided a grazing environment conducive to forage intake by animals that resulted in efficient use of the pasture. In response to the improved canopy structure, the cows grazed an average of 60 fewer minutes. A HBC greater than 34 % of legumes in the pastures allows for the postponement of legume oversowing until the next growing season.

    Two hundred and sixty-five grain legume cultivars developed using induced mutations have been released in 32 countries. A maximum number of cultivars have been released in soybean (58), followed by common bean (50), groundnut (44), pea (32) and mungbean (14). Gamma or x-ray exposures of seeds led to the direct development of 111 cultivars, while neutron and chemical mutagen treatments resulted in 8 and 36 cultivars respectively. One hundred and three cultivars have been developed using mutants in cross breeding. Attempts have been made to estimate the successful dose range for gamma and x-rays, defined as the dose range, which led to the development, registration and release of a maximum number of mutant cultivars. Exposures to seeds ranging between 100-200 Gy in all grain legumes, except faba bean, resulted in 49 out of 111 cultivars being developed as direct mutants. Successful doses reported for faba bean are lower than 100 Gy. Modified crop plant characters are listed. Besides the development of new cultivars, a large number of induced mutants that show altered nodulation pattern have been isolated in grain legumes. Such mutants have made a significant contribution in basic studies on host-symbiont interactions and towards cloning of plant genes related to symbiosis and nitrogen fixation. Their exploitation in breeding programs for enhancing nitrogen fixation is just beginning. Available information on nodulation mutants in grain legume crops is summarised. Mainly, four types of nodulation mutants have been isolated. They show either: no nodulation (nod -), few nodules (nod +/-), ineffective nodulation (Fix-), hypernodulation (nod ++) or hypernodulation even in the presence of otherwise inhibitory nitrate levels (nts). Hypernodulating and nts mutants are of great interest. A soybean cultivar incorporating nts trait has been released in Australia. (author)

    Defining the quality of the university education system is not easy. Institutions of higher education, through curriculum are hoped to provide the knowledge, wisdom and personality of students. It is questionable of how far Quality and Productivity Improvement Program (PPKP) are capable to ensure the courses offered relevant and effective in preparing the students for job market. The effectiveness of a university to undertake responsibilities and the impact given to students even after they graduate can be a measure of education quality at university. So, the quality of education can be enhanced and improved from time to time. In general, this study is aims to determine the effectiveness of PPKP's education system from the perspective of their alumni as well as their satisfaction and the importance level based on how PPKP be able to meet their needs. In overall, summary of open-ended questions from the questionnaire, Importance-Performance analysis and correlation analysis were conducted for this study. Based on result, it appears that there are still some deficiencies that can be improve, particularly in terms of teaching skills and PPKP's relationships with external organizations to enable knowledge be channel effectively. Importance-Performance analysis highlights some topics or courses that should be offered by PPKP based on their importance in industrial practice. Summary of the results of correlation analysis was found that women are more positive and not too demanding compared to men. In addition, it is found that the responsibilities and workload of the older generations, higher income and a high level of experience demands them to use and practice what they have learned during their studies at PPKP. Results of this study are hoped could be used to improve the quality of education system at PPKP.

    This paper describes Compression Planning, an innovative approach for planning in groups. This participative and structured approach is especially suitable for technical and highly regulated organizations. Compression Planning was applied to the first organization-wide effort at training integration for regulatory compliance, at Battelle Pacific Northwest Laboratory (PNL), a multi-program national laboratory. The planning process was judged as measurably superior to PNL's customary planning. Within 10 days a training policy was issued and an action plan drafted. The participants produced a report identifying and prioritizing 33 key training issues; began to data gather and solicit input from personnel Lab-wide, producing a 2-volume training inventory; and formulated 14 recommendations for implementation. Two years later the plan is still evolving, as PNL training continues to develop, consistent with Continuous Improvement Process objectives

    The female prison population has increased dramatically in recent years. Most women prisoners are involved with drugs, and as many as 25 percent are pregnant or have delivered within the past year. Reproductive health and drug treatment services for women in prison are inadequate, if they are available at all, and although illicit drugs are readily available in prison, drug-involved pregnant women often are incarcerated to protect fetal health. Studies of pregnancy outcome among women prisoners have demonstrated high rates of perinatal mortality and morbidity. This article examines issues related to pregnancy among women prisoners and describes an innovative residential program designed for pregnant, drug-dependent women in a state adult corrections system. Social workers can play an important role in promoting policy reform and improved services for this underserved population.

    Recent studies have demonstrated that patients who attend more cardiac rehabilitation (CR) sessions have lower subsequent mortality rates than those who attend fewer sessions. We analyzed the impact of several phased-in policy and process changes implemented to increase patient participation in CR. In March 2010, our CR program changed from a policy of individualizing the recommended number of CR sessions per patient to a policy that recommended all 36 CR sessions. In October 2010, we introduced a 7-minute video describing the benefits of CR. In August 2011, we introduced a motivational program that rewarded patients after every sixth CR session. The number of CR sessions attended was determined through review of billing records. Enrollment and completion were defined as attending ≥1 session and ≥30 sessions, respectively. We identified 1103 patients sequentially enrolled in CR between May 2009 and January 2012. Overall, the median number of sessions per patient improved from 12 to 20 (P attendance by a median of 3 sessions per patient (P = .04), but this effect was limited to local CR participants. Financial analysis suggested that for every $100 spent on motivational rewards, patients attended an additional 6.6 (95% CI, -1 to 14) sessions of CR. Quality improvement activities significantly increased CR participation. Wide implementation of such programs may favorably impact patient participation in CR and potentially decrease the rate of subsequent cardiac events.

    1988-11-01

    The status of the Department of Energy's (DOE) implementation of recommendations in our two reports on DOE's personnel security clearance program was determined. The recommendations were aimed at improving the timeliness, accuracy, and efficiency of personnel security clearance decisions. Specifically, the objective was to determine and report on steps DOE is taking to implement these recommendations. In summary, it was found that DOE has either initiated action or is studying ways to address all the recommendations, but none of the recommendations have been completely implemented. The effectiveness of the DOE actions will depend, in part, on the adequacy of its internal control system for overseeing and evaluating program operations. DOE's personnel security clearance program is intended to provide reasonable assurance that personnel with access to classified information and materials are trustworthy. The Department requests that the Office of Personnel Management or the Federal Bureau of Investigation collect personal data on each person who requires such access to do his or her job. Based on these background investigations, DOE officials authorize individuals whose personal histories indicate that they are trustworthy to have access to classified information, secured facilities, and controlled materials as needed to perform their jobs. DOE has five types of these authorizations or personnel security clearances and must update information on personnel holding each type at 5-year intervals to confirm their continuing reliability. The five types are based on the types of security interests to which the person needs access, e.g., persons needing nuclear weapons-related data must have a Q clearance, and persons with a top secret clearance can have access to national security data classified as top secret

    An important objective of education is to improve clinical competence and hence confidence of students. Ample evidence on effectiveness of medical outreach programs is available but data pertaining to effectiveness of dental outreach, especially from developing countries, are still limited. The present study was undertaken to assess effectiveness of outreach placements on clinical confidence and communication skills of Indian dental students. A non-randomized trial was conducted in three randomly selected dental colleges of Bangalore city, India, amongst 89 students pursuing internship programs. Subjects were put into two groups: outreach (study group) and dental school based only (control group). A pre-tested, self-administered questionnaire was used to evaluate the change in clinical confidence and communication skills of both groups from baseline and after 3 months of follow-up via global self-assessment test, then-test and transition judgment. Outcome measures were analysed using t-test. Global assessment revealed outreach group confidence level was higher in comparison to dental school based group only (4.37±0.49 vs 4.04±0.21, pp=0.04). Transition judgement rated an increase in their confidence significantly higher than the dental school based group only (4.24±0.91 vs 2.54±0.66, peducation to achieve an overall professionally trained dentist.

    Full Text Available The goal of the Young Scientist Program (YSP at Washington University School of Medicine in St. Louis (WUSM is to broaden science literacy and recruit talent for the scientific future. In particular, YSP seeks to expose underrepresented minority high school students from St. Louis public schools (SLPS to a wide variety of careers in the sciences. The centerpiece of YSP, the Summer Focus Program (SFP, is a nine-week, intensive research experience for competitively chosen rising high school seniors (Scholars. Scholars are paired with volunteer graduate student, medical student, or postdoctoral fellow mentors who are active members of the practicing scientific community and serve as guides and exemplars of scientific careers. The SFP seeks to increase the number of underrepresented minority students pursuing STEM undergraduate degrees by making the Scholars more comfortable with science and science literacy. The data presented here provide results of the objective, quick, and simple methods developed by YSP to assess the efficacy of the SFP from 2006 to 2013. We demonstrate that the SFP successfully used formative evaluation to continuously improve the various activities within the SFP over the course of several years and in turn enhance student experiences within the SFP. Additionally we show that the SFP effectively broadened confidence in science literacy among participating high school students and successfully graduated a high percentage of students who went on to pursue science, technology, engineering, and mathematics (STEM majors at the undergraduate level.

    Full Text Available Growth was evaluated three tropical forage legumes in two cropping systems: silvopastoral system (SSP and full sun. A completely randomized design was adopted in factorial three legumes (estilosanthes cv. Campo Grande (Stylozanthes macrocephala x Stylozanthes capitata, tropical kudzu (Pueraria phaseoloides (Roxb. Benth and macrotiloma (Macrotyloma axillare cv. Java x two farming systems, with 4 repetitions. A eucalyptus SSP already deployed, with spatial arrangement of 12 x 2 m between trees was used. Legumes were planted in January 2014 a uniform cut being made in May 2014. The court assessment was carried out 125 days after the uniformity cut. There was difference for mass production of dry legumes (PMMSL between cultivation systems, evidencing increased productivity in the farming full sun. The macrotiloma showed higher PMSL (5.29 kg DM ha-1 cut-1, while the kudzu obtained the lowest yield (3.42 kg DM ha-1 cut-1 in the sun growing full. The cultivation of legumes in SSP increased the levels of mineral matter, crude protein and neutral detergent fiber. The shade provided by the SSP caused a reduction in the mass of dry matter production, but also altered the chemical composition of the studied legumes.

    Purpose The Accreditation Council for Graduate Medical Education (ACGME) expects programs to engage in ongoing, meaningful improvement, facilitated in part through an annual process of program assessment and improvement. The Duke University Hospital Office of Graduate Medical Education (OGME) used an institutional practice-based learning and improvement strategy to improve the annual evaluation and improvement of its programs. Methods The OGME implemented several strategies including the development and dissemination of a template for the report, program director and coordinator development, a reminder and tracking system, incorporation of the document into internal reviews, and use of incentives to promote program adherence. Results In the first year of implementation (summer 2005), 27 programs (37%) submitted documentation of their annual program evaluation and improvement to the OGME; this increased to 100% of programs by 2009. A growing number of programs elected to use the template in lieu of written minutes. The number of citations related to required program review and improvement decreased from 12 in a single academic year to 3 over the last 5 years. Conclusion Duke University Hospital's institutional initiative to incorporate practice-based learning and improvement resulted in increased documentation, greater use of a standardized template, fewer ACGME-related citations, and enhanced consistency in preparing for ACGME site visits.

    A pot experiment was designed to evaluate the interactive effects of multifunctional microbial inoculation treatments and rock phosphate (RP) application on N and P uptake by alfalfa through the use of 15 N and 32 P isotopic dilution approaches. The microbial inocula consisted of a wild type (WT) Rhizobium meliloti strain, the arbuscular mycorrhizal (AM) fungus Glomus mosseae (Nicol. and Gerd.) Gerd. and Trappe, and a phosphate solubilizing rhizobacterium (Enterobacter sp.). Inoculated microorganisms were established in the root tissues and/or in the rhizosphere soil of alfalfa plants (Medicago sativa L.). Improvements in N and P accumulation in alfalfa corroborate beneficial effects of Rhizobium and AM interactions. Inoculation with selected rhizobacteria improved the AM effect on N or P accumulation in both the RP-added soil and in the non RP-amended controls. Measurements of the 15 N/ 14 N ratio in plant shoots indicate an enhancement of the N 2 fixation rates in Rhizobium-inoculated AM-plants, over that achieved by Rhizobium in non-mycorrhizal plants. Whether or not RP was added, AM-inoculated plants showed a lower specific activity ( 32 P/ 31 P) than did their comparable non-mycorrhizal controls, suggesting that the plant was using otherwise unavailable P sources. The phosphate-solubilizing, AM-associated, microbiota could in fact release phosphate ions, either from the added RP or from the indigenous 'less-available' soil phosphate. A low Ca concentrations in the test soil may have benefited P solubilization. Under field conditions, the inoculation with AM fungi significantly increased plant biomass and N and P accumulation in plant tissues. Phosphate-solubilizing rhizobacteria improved mycorrhizal responses in soil dually receiving RP and organic matter amendments. Organic matter addition favoured RP solubilization. This, together with a tailored microbial inoculation, increased the agronomic efficiency of RP in the test soil that was Ca deficient at neutral

  4. Immunosuppression during Rhizobium-legume symbiosis.

    2014-01-01

    Rhizobium infects host legumes to elicit new plant organs, nodules where dinitrogen is fixed as ammonia that can be directly utilized by plants. The nodulation factor (NF) produced by Rhizobium is one of the determinant signals for rhizobial infection and nodule development. Recently, it was found to suppress the innate immunity on host and nonhost plants as well as its analogs, chitins. Therefore, NF can be recognized as a microbe/pathogen-associated molecular pattern (M/PAMP) like chitin to induce the M/PAMP triggered susceptibility (M/PTS) of host plants to rhizobia. Whether the NF signaling pathway is directly associated with the innate immunity is not clear till now. In fact, other MAMPs such as lipopolysaccharide (LPS), exopolysaccharide (EPS) and cyclic-β-glucan, together with type III secretion system (T3SS) effectors are also required for rhizobial infection or survival in leguminous nodule cells. Interestingly, most of them play similarly negative roles in the innate immunity of host plants, though their signaling is not completely elucidated. Taken together, we believe that the local immunosuppression on host plants induced by Rhizobium is essential for the establishment of their symbiosis.

  5. Pollen structure and function in caesalpinioid legumes.

    Banks, Hannah; Rudall, Paula J

    2016-03-01

    A diverse range of pollen morphologies occurs within the large, paraphyletic legume subfamily Caesalpinioideae, especially among early-branching lineages. Previous studies have hypothesized an association between surface ornamentation and pollination syndrome or other aspects of pollen function such as desiccation tolerance and adaptations to accommodate volume changes. We reviewed caesalpinioid pollen morphology using light microscopy, scanning and transmission electron microscopy, in combination with a literature survey of pollination vectors. Pollen structural diversity is greatest in the early-branching tribes Cercideae and Detarieae, whereas Cassieae and Caesalpinieae are relatively low in pollen diversity. Functional structures to counter desiccation include opercula (lids) covering apertures and reduced aperture size. Structures preventing wall rupture during dehydration and rehydration include different forms of colpi (syncolpi, parasyncolpi, pseudocolpi), striate supratectal ornamentation, and columellate or granular wall structures that resist tensile or compressive forces respectively. Specialized aperture structures (Zwischenkörper) may be advantageous for efficient germination of the pollen tube. In Detarieae and Cercideae in particular, there is potential to utilize pollen characters to estimate pollination systems where these are unknown. Supratectal verrucae and gemmae have apparently evolved iteratively in Cercideae and Detarieae. At the species level, there is a potential correlation between striate/verrucate patterns and vertebrate pollination. © 2016 Botanical Society of America.

The present study was carried out with the following aims: (1 to identify and quantify the individual phenolic acid and determine the total phenolic content (TPC; (2 to assess their antioxidant activity, inhibition activities of α-glucosidase, tyrosinase, and formation of advanced glycation endproducts; and (3 to investigate correlations among the phytochemicals and biological activity. Common bean possesses the highest antioxidant activity and advanced glycation endproducts formation inhibition activity. Adzuki bean has the highest α-glucosidase inhibition activity, and mung bean has the highest tyrosinase inhibition activity. There are significant differences in phytochemical content and functional activities among the bean species investigated. Selecting beans can help treat diseases such as dermatological hyperpigmentation illness, type 2 diabetes and associated cardiovascular diseases.

    Peanut, soybean, sesame and lentil are members of legumes worldwide consumed by human that can induce food allergy in genetically predisposed individuals. Several protein allergens, mainly water-soluble, have been described. We studied the non water-soluble fraction from these 4 food sources using immunoproteomics tools and techniques. Flour extracts were solubilized in detergent and chaotropes and analysed in 1 and 2 dimensional gel electrophoresis (2D). Results showed numerous proteins exhibiting wide ranges of isoelectric points and relative molecular masses. When IgE immunoreactivities of 18 food allergy patients were individually tested in 1 and 2D western-blots, a very diversified IgE repertoire was observed, reflecting extensive cross-reactivities but also co-sensitizations. Besides already well known and characterized allergens, mass spectrometry analysis allowed the identification of 22 allergens undescribed until now: 10 in peanut, 2 in soybean, 3 in sesame and 7 in lentil. Three allergens are legume storage proteins and the others belong to transport proteins, nucleotide binding proteins and proteins involved in the regulation of metabolism. Seven proteins are potentially similar to allergens described in plants and fungi and 11 are not related to any known allergen. Our results contribute to increase the repertoire of legume allergens that may improve the diagnosis, categorize patients and thus provide a better treatment of patients.

    Advanced training of healthcare professionals active in organ donation is highlighted as a major means to overcome organ shortage. The objective of this study was to improve donation rates in the selected European target areas (TAs) by providing an advanced training program. A prospective intervention study was conducted in 25 TAs with active donor programs from 17 European countries, between 2007 and 2009. A training program based on collaborative methodology was designed at three different professional levels (health workers awareness, junior transplant coordinators, managers). Courses evaluation scores and donation figures in each TA were collected and compared before and after intervention.

    To determine the effectiveness of the Spirometry 360 distance learning quality improvement (QI) program for enhancing the processes and outcomes of care for children with asthma. Cluster randomized controlled trial involving 25 matched pairs of pediatric primary care practices. Practices were recruited from 2 practice-based research networks: the Slone Center Office-based Research Network at Boston University, Boston, Mass, and the Puget Sound Pediatric Research Network, Seattle, Wash. Study participants included providers from one of the 50 enrolled pediatric practices and 626 of their patients with asthma. Process measures assessed included spirometry test quality and appropriate prescription of asthma controller medications. Outcome measures included asthma-specific health-related quality of life, and outpatient, emergency department, and inpatient utilization for asthma. At baseline, 25.4% of spirometry tests performed in control practices and 50.4% of tests performed in intervention practices were of high quality. During the 6-month postintervention period, 28.7% of spirometry tests performed in control practices and 49.9% of tests performed in intervention practices were of high quality. The adjusted difference-of-differences analysis revealed no intervention effect on spirometry test quality. Adjusted differences-of-differences analysis also revealed no intervention effect on appropriate use of controller medications or any of the parent- or patient-reported outcomes examined. In this study, the Spirometry 360 distance learning QI program was ineffective in improving spirometry test quality or parent- or patient-reported outcomes. QI programs like the one assessed here may need to focus on practices with lower baseline performance levels or may need to be tailored for those with higher baseline performance.

    Border (B) description of melanoma and other pigmented skin lesions is one of the most important tasks for the clinical diagnosis of dermoscopy images using the ABCD rule. For an accurate description of the border, there must be an effective skin tumor area extraction (STAE) method. However, this task is complicated due to uneven illumination, artifacts present in the lesions and smooth areas or fuzzy borders of the desired regions. In this paper, a novel STAE algorithm based on improved dynamic programming (IDP) is presented. The STAE technique consists of the following four steps: color space transform, pre-processing, rough tumor area detection and refinement of the segmented area. The procedure is performed in the CIE L(*) a(*) b(*) color space, which is approximately uniform and is therefore related to dermatologist's perception. After pre-processing the skin lesions to reduce artifacts, the DP algorithm is improved by introducing a local cost function, which is based on color and texture weights. The STAE method is tested on a total of 100 dermoscopic images. In order to compare the performance of STAE with other state-of-the-art algorithms, various statistical measures based on dermatologist-drawn borders are utilized as a ground truth. The proposed method outperforms the others with a sensitivity of 96.64%, a specificity of 98.14% and an error probability of 5.23%. The results demonstrate that this STAE method by IDP is an effective solution when compared with other state-of-the-art segmentation techniques. The proposed method can accurately extract tumor borders in dermoscopy images. © 2011 John Wiley & Sons A/S.

This review article summarizes literature reviews and resource books on faculty development. It tackled why FDP is important, history of FDP in the past years, and questioned whether FDP produced any positive effect on students' academic achievement as well as the different methods to assess FDPs effectiveness. The review also discussed how to establish FDP, presented its ideal structure, features that make FDP effective, and outlined the barriers to its successful implementation as well as the future vision. This report also highlighted the situation of FDP in Saudi Arabia. Finally, the review concluded that professional FDPs produce promising outcomes in the learning and teaching practices and recommended that teachers in higher education should attend FDP training activities on regular basis and that the scope of planned FDPs should extend beyond the health professions discipline, to include social skills necessary for collaboration, professional growth as well as management, and leadership abilities.

  13. Transport processes of the legume symbiosome membrane

    Directory of Open Access Journals (Sweden)

    Victoria C Clarke

    2014-12-01

    Full Text Available The symbiosome membrane (SM is a physical barrier between the host plant and nitrogen-fixing bacteria in the legume-rhizobium symbiosis, and represents a regulated interface for the movement of solutes between the symbionts that is under plant control. The primary nutrient exchange across the SM is the transport of a carbon energy source from plant to bacteroid in exchange for fixed nitrogen. At a biochemical level two channels have been implicated in movement of fixed nitrogen across the SM and a uniporter that transports monovalent dicarboxylate ions has been characterized that would transport fixed carbon. The aquaporin NOD26 may provide a channel for ammonia, but the genes encoding the other transporters have not been identified. Transport of several other solutes, including calcium and potassium, have been demonstrated in isolated symbiosomes, and genes encoding transport systems for the movement of iron, nitrate, sulfate and zinc in nodules have been identified. However, definitively matching transport activities with these genes has proved difficult and many further transport processes are expected on the SM to facilitate the movement of nutrients between the symbionts. Recently, work detailing the SM proteome in soybean has been completed, contributing significantly to the database of known SM proteins. This represents a valuable resource for the identification of transporter protein candidates, some of which may correspond to transport processes previously described, or to novel transport systems in the symbiosis. Putative transporters identified from the proteome include homologues of transporters of sulfate, calcium, peptides and various metal ions. Here we review current knowledge of transport processes of the SM and discuss the requirements for additional transport routes of other nutrients exchanged in the symbiosis, with a focus on transport systems identified through the soybean SM proteome.

    Development and technological transfer of functional pastas extended with legumes. Semolina pasta is a highly consumed foodstuff, the biological value of which is low because its protein is deficient in lysine. However, if the semolina is extended with legumes rich in this essential aminoacid, not only and aminoacid supplementation is produced, but also the dietary fibre and minerals are increased. In this work, pastas extended in 10% with a white variety of Phaseolus vulgaris and with Cajanus cajan were produced on a pilot plant scale, and this technology was transferred to a cooperative producing artisanal pastas. The cooking qualities and the physical, chemical, and nutritional characteristics of the pastas were evaluated, as well as the sensorial acceptability in institutionalized elderly people. The extension of the pastas with legume flours increased the optimum cooking time (15 to 20%), the weight (20% and 25%), and the loss of solids by cooking. Similarly, the functional value of the pastas increased by increasing the contents of minerals and dietary fibre. The protein content, as well as the protein digestibility in vitro also increased; however, the parameters of colour L, a and b, and the total starch content of the pastas decreased. At consumer level, the pastas extended with legumes had a good acceptability, for what it was concluded that the extension of the semolina with legume flours in the manufacture of pastas is technologically feasible.

    Biochar application is gaining popularity in agriculture system as prime technology in sustainable context. Field experiments were conducted at the Research Farm of the University of Agriculture Peshawar, during 2011-2013. Wheat-maize-wheat cropping pattern was followed with the adjustment of legumes in summer gap (land available after wheat harvest till maize sowing). Legumes i.e., mungbean, cowpea and Sesbania with a fallow were adjusted in the summer gap with and without biochar application. Biochar was applied at the rate of 0 and 50 t ha-1 with four N levels of 0, 60, 90 and 120 kg ha-1 to subsequent wheat crop. Biohcar application and plots previously sown with legumes improved thousand grain weight of wheat crop. Nitrogen application increased thousand spikes m-2, grains weight, grain and biological yield. It is concluded that integration of biochar and legumes could be a useful strategy for enhancing the overall farm profitability and productivity of cereal-based systems by providing increased yields from this additional summer gap crop.

    2013-12-01

    Full Text Available The effects of roots are generally not considered in studies assessing crop responses to green manure. However, measuring such effects can contribute to a better understanding of crop rotation. In two experiments, we evaluated the content of legume-N in crop tissue and the fertilizer value of the roots and shoots of two legume species. Roots, shoots, or whole plants of the legumes sunhemp (Crotalaria juncea and jack beans (Canavalia ensiformis were cropped as green manure to supply nitrogen to cabbage crops (Brassica oleracea var. capitata. The principle of the A-value technique was applied to estimate the fertilizer value of each plant part. In a pot experiment, both the content of legume-N in cabbage and the fertilizer value of the whole plant was higher than the shoots, which was in turn higher than that of the roots. In field condition, roots had a decreasing effect on the N content of cabbage plants. Growing cabbage on legume root residue resulted in an increased absorption of 15N-urea, resulting in negative values ​​for legume-N content: -13.59 g kg-1 and -3.51 g kg-1 for sunhemp and jack beans, respectively. Suggesting both low N supply by roots and N immobilization in soil organic matter or microbial biomass. Future research should focus on estimating the net N acquisition by plants from root residues under field conditions, where rooting patterns and biomass distribution differ from those in pot experiments, therefore giving a more realistic quantitative estimate.

    Hi-Z Technology, Inc. (Hi-Z) is currently developing four different auxiliary generator designs that are used to convert a portion (5 to 20%) of the waste heat from vehicle engines exhaust directly to electricity. The four designs range from 200 Watts to 10 kW. The furthest along is the 1 kW Diesel Truck Thermoelectric Generator (DTTEG) for heavy duty Class 8 Diesel trucks, which, under this program, has been subjected to 543,000 equivalent miles of bouncing and jarring on PACCAR's test track. Test experience on an earlier version of the DTTEG on the same track showed the need for design modifications incorporated in DTTEG Mod 2, such as a heavy duty shock mounting system and reinforcement of the electrical leads mounting system, the thermocouple mounting system and the thermoelectric module restraints. The conclusion of the 543,000 mile test also pointed the way for an upgrading to heavy duty hose or flex connections for the internal coolant connections for the TEG, and consideration of a separate lower temperature cooling loop with its own radiator. Fuel savings of up to $750 per year and a three to five year payback are believed to be possible with the 5 % efficiency modules. The economics are expected to improve considerably to approach a two year payback when the 5 kW to 10 kW generators make it to the market in a few years with a higher efficiency (20%) thermoelectric module system called Quantum Wells, which are currently under development by Hi-Z. Ultimately, as automation takes over to reduce material and labor costs in the high volume production of QW modules, a one year payback for the 5 kW to10 kW generator appears possible. This was one of the stated goals at the beginning of the project. At some future point in time, with the DTTEG becoming standard equipment on all trucks and automobiles, fuel savings from the 25% conversion of exhaust heat to useable electricity nationwide equates to a 10% reduction in the 12 to 15 million barrels per day of

    The Department of Energy's (DOE's) Environmental Management Program is the country's largest and most sophisticated environmental program to date. The rapid expansion of the DOE's environmental restoration efforts has led to increased scrutiny of its management processes and systems. As the program continues to grow and mature, maintaining adequate accountability for resources and clearly communicating progress will be essential to sustaining public confidence. The Office of Environmental Management must ensure that adequate processes and systems are in place at Headquarters, Operation Offices, and contractor organizations. These systems must provide the basis for sound management, cost control, and reporting. To meet this challenge, the Office of Environmental Restoration introduced the Management Action Plan process. This process was designed to serve three primary functions: (1) define the program's management capabilities at Headquarters and Operations Offices; (2) describe how management initiatives address identified program deficiencies; and (3) identify any duplication of efforts or program deficiencies. The Environmental Restoration Management Action Plan is a tracking, reporting, and statusing tool, used primarily at the Headquarters level, for assessing performance in key areas of project management and control. BY DOE to communicate to oversight agencies and stakeholders a clearer picture of the current status of the environmental restoration project management system. This paper will discuss how Management Action Plans are used to provide a program-wide assessment of management capabilities

    Full Text Available Immunization programs are one of the most well-recognized and successful public health programs across the world. The immunization programs have achieved significant successes in a number of countries; however, the coverage with available vaccines remains sub-optimal in many low- and middle-income countries (LMICs. This article, based upon extensive review of literature and using universal immunization program (UIP in India as a case study, summarizes the latest developments and initiatives in the area of vaccination and immunization in the last few years. The article analyzes initiatives under UIP in India from the "health system approach" and argues that it is possible to increase coverage with available vaccines and overall program performance by focused attention on various functions of health systems. It also discusses the emerging evidence that health systems could be strengthened prior to the introduction of new interventions (vaccines included and the introduction of new interventions (including vaccines could be planned in a way to strengthen the health systems. It concludes that immunization programs could be one of the entry points for strengthening health systems in the countries and lessons from vaccine introduction could pave pathway for scaling up other health interventions and therefore, could contribute to advancing Universal Health Coverage (UHC.

    There is still controversy surrounding the ability of tannins to modulate the ruminal biohydrogenation (BH) of fatty acids (FA) and improve the lipid profile of milk or meat without conferring a negative response in the digestive utilization of the diet. Based on this, an in vitro trial using batch cultures of rumen microorganisms was performed to compare the effects of two legume hays with similar chemical composition but different tannin content, alfalfa and sainfoin (Onobrychis viciifolia), on the BH of dietary unsaturated FA and on the ruminal fermentation. The first incubation substrate, alfalfa, was practically free of tannins, while the second, sainfoin, contained 3.5% (expressed as tannic acid equivalents). Both hays were enriched with sunflower oil as a source of unsaturated FA. Most results of the lipid composition analysis (e.g., greater concentrations of 18:2n-6, cis-9 18:1 or total polyunsaturated FA in sainfoin incubations) showed the ability of this tannin-containing legume to inhibit the BH process. However, no significant differences were detected in the accumulation of cis-9 trans-11 conjugated linoleic acid, and variations in trans-11 18:1 and trans-11 cis-15 18:2 did not follow a regular pattern. Regarding the rumen fermentation, gas production, ammonia concentration and volatile FA production were lower in the incubations with sainfoin (‒17, ‒23 and ‒11%, respectively). Thus, although this legume was able to modify the ruminal BH, which might result in improvements in the meat or milk lipid profile, the present results were not as promising as expected or as obtained before with other nutritional strategies.

    Full Text Available Bioactive compounds, which are naturally produced in plants, have been concerned with the food and pharmaceutical industries because of the pharmacological effects on humans. In this study, the individual phenolics of six legumes during germination and antioxidant capacity from sprout extracts were determined. It was found that the phenolic content significantly increased during germination in all legumes. Peanuts showed the strongest antioxidant capacity in both the DPPH• (1,1-diphenyl-2-picrylhydrazyl method and the reducing power assay (32.51% and 84.48%, respectively. A total of 13 phenolic acids were detected and quantified. There were 11 phenolic constituents identified in adzuki beans; 10 in soybeans; 9 in black beans, mung beans, and white cowpeas; and 7 compounds in peanuts. Sinapic acid and cinnamic acid were detected in all six legume sprouts, and their quantities in germinated peanuts were the highest (247.9 µg·g−1 and 62.9 µg·g−1, respectively. The study reveals that, among the investigated legumes, germinated peanuts and soybeans obtained maximum phenolics and antioxidant capacity.

    A pot-culture study was made at Indian Agricultural Research Institute, New Delhi to study the native P feeding power of six rainy season legumes (green gram, black gram, cowpea, pigeon pea, soyabean and groundnut). Ordinary superphosphate tagged with 32 P was used in the study. At the first harvest (30 days after seeding) soybean and cowpea and at the second harvest (45 days after sowing) cowpea and groundnut removed more P than the other legumes. Pigeon pea removed the least P due to its slow growth. The tracer studies showed that during the first 30 days, groundnut, pigeon pea and soyabean were relatively better feeders of native soil P than the other legumes. Some varietal differences with respect to their capacity to feed on native soil P were also observed and in groundnut the varieties AK-12-24 and Jyoti removed more soil P than the variety NG-268. Differences between the legumes with respect to feeding on native soil P were much less at the second harvest (45 days after seeding). (author)

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available Many social programs, and most poverty–fighting programs, are based on the assumption that increasing income automatically translates into a raise in well–being. This investigation questions this assumption on the basis of the subjective well–being literature and on empirical analyses from Mexico. It is shown that it is possible to get people out of income poverty without necessarily increasing their well–being. The paper enunciates some general principles that can enhance social programs. It is argued that it is fine to be concerned about getting people out of income poverty, but it is even better to be concerned about placing them in a situation that favors their satisfaction with life.

    Wellness programs are designed to help individuals maintain or improve their health. This article describes how a reporting process can be used to help manage and improve a wellness program. Beginning in 2014, a wellness pilot program became available in New Jersey for individuals with an AARP Medicare Supplement Insurance plan insured by UnitedHealthcare Insurance Company. The program has since expanded to include Missouri, Texas, Alabama, and Washington. This wellness program includes an online health portal, one-on-one telephonic coaching, gym membership discounts, and local health events. To assure smooth program operations and alignment with program objectives, weekly and monthly reports are produced. The weekly report includes metrics on member engagement and utilization for the aforementioned 4 program offerings and reports on the last 4 weeks, as well as for the current month and the current year to date. The monthly report includes separate worksheets for each state and a summary worksheet that includes all states combined, and provides metrics on overall engagement as well as utilization of the 4 program components. Although the monthly reports were used to better manage the 4 program offerings, the weekly reports help management to gauge response to program marketing. Reporting can be a data-driven management tool to help manage wellness programs. Reports provide rapid feedback regarding program performance. In contrast, in-depth program evaluations serve a different purpose, such as to report program-related savings, return on investment, or to report other longer term program-related outcomes.

    Legumes are involved in IgE mediated food allergy in many countries. Avoidance of allergenic food is the only way to avoid symptomatic reaction. The present study investigated the effect of enzymatic hydrolysis on the allergenicity of three legumes - kidney bean (Phaseolus vulgaris), black gram (Vigna mungo) and peanut (Arachis hypogaea). Soluble protein extracts of the study legumes were sequentially treated by Alcalase(®) and Flavourzyme(®). Allergenicity of hydrolysates was then determined by ELISA, immunoblot, stripped basophil histamine release and skin prick test (SPT). Hydrolysis resulted in the loss of all IgE binding fractions determined by immunoblot in the three legumes. Specific IgE binding in ELISA was reduced by 62.2 ± 7.7%, 87.1 ± 9.6% and 91.8 ± 7.2% in the hydrolysates of kidney bean, black gram and peanut, respectively (p < 0.01). The release of histamine was decreased significantly when sensitized basophils were challenged with hydrolysates as compared to raw extracts. Significant reduction in the biopotency of hydrolysates was also observed in SPT where only 1/10 kidney bean-sensitive individuals, 2/6 black gram-sensitive individuals and 1/7 peanut-sensitive individuals were found positive to their respective hydrolysates. In conclusion, enzymatic hydrolysis is effective in attenuating allergenicity of legume proteins and may be employed for preparing hypoallergenic food extracts. Copyright © 2014 Elsevier Ltd.

  8. Traits affecting early season nitrogen uptake in nine legume species

    2017-02-01

    Full Text Available Legume crops are known to have low soil N uptake early in their life cycle, which can weaken their ability to compete with other species, such as weeds or other crops in intercropping systems. However, there is limited knowledge on the main traits involved in soil N uptake during early growth and for a range of species. The objective of this research was to identify the main traits explaining the variability among legume species in soil N uptake and to study the effect of the soil mineral N supply on the legume strategy for the use of available N sources during early growth. Nine legume species were grown in rhizotrons with or without N supply. Root expansion, shoot and root biomass, nodule establishment, N2 fixation and mineral soil N uptake were measured. A large interspecific variability was observed for all traits affecting soil N uptake. Root lateral expansion and early biomass in relation to seed mass were the major traits influencing soil N uptake regardless of the level of soil N availability. Fenugreek, lentil, alfalfa, and common vetch could be considered weak competitors for soil N due to their low plant biomass and low lateral root expansion. Conversely, peanut, pea, chickpea and soybean had a greater soil N uptake. Faba bean was separated from other species having a higher nodule biomass, a higher N2 fixation and a lower seed reserve depletion. Faba bean was able to simultaneously fix N2 and take up soil N. This work has identified traits of seed mass, shoot and root biomass, root lateral expansion, N2 fixation and seed reserve depletion that allowing classification of legume species regarding their soil N uptake ability during early growth.

  10. Contribution of legumes to the soil N pool.

    2010-05-01

    Grain legumes can be used for nitrogen acquisition in different ways in sustainable agriculture (Fustec et al., 2009). They are seen as a tool to reduce mineral N fertilizers in cropping systems. However, estimates of biological N fixation, N balance and N benefit either for the following crop or in mixed crops, remain unclear. The contribution of legumes to the soil N pool is difficult to measure, especially N rhizodeposition, since it is a critical point for assessing N benefits for other crops and for soil biological activity, and for reducing water pollution (Mayer et al., 2003). We adapted and refined the cotton-wick 15N stem labeling method for measuring the amount of soil N derived from rhizodeposition by field peas (Mahieu et al., 2007, 2009). The method was tested in different conditions in the field and in the greenhouse with various pea varieties and isolines. In addition, we used the cotton-wick method for assessing N transfers from pea to neighbouring durum wheat. In the greenhouse, a positive relationship was found between the amount of N rhizodeposits and the legume N content. N rhizodeposition was about 15% of the plant N and 30% in the field. In field pea / durum wheat intercrops, plant-plant N transfers were quantified and found to be bidirectional. Such results should be taken into account when estimating N benefits from biological N fixation by a grain legume crop and for the prediction of N economies in legume-based cropping systems. More studies dealing with rhizodeposit compounds and soil biological activity would now be necessary. Fustec et al. 2009. Agron. Sustain. Dev., DOI 10.1051/agro/2009003, in press. Mahieu et al. 2007.

Agreement was also reached with Georgia Power Co., Power Authority of the State of New York, and Commonwealth Edison Co. for monitoring and data collection at Hatch 1, FitzPatrick, and Quad Cities 1 nuclear plants, respectively. The objective was to identify, develop, and demonstrate improved refueling, maintenance, and inspection procedures and equipment. The improvements recommended in this study are applicable to BWR nuclear plants currently in operation as well as those in the design and construction phases. The recommendations and outage information can be used as a basis to plan and conduct the first outages of new plants and to improve the planning and facilities of currently operating plants. Many of the recommendations can readily be incorporated in plants currently in the design and construction phases as well as in the design of future plants. Many of these recommended improvements can be implemented immediately by utilities without further technical development

    Highlights: • Improving DSM program impacts by targeting high energy users. • DSM energy savings potential hinges on pre-participation performance. • Targeting can benefit different utilities and energy efficiency programs. • Overall performance can be improved by up to 250% via targeting strategies. - Abstract: Electric utilities, government agencies, and private interests in the US have committed and continue to invest substantial resources – including billions of dollars of financial capital – in the pursuit of energy efficiency and conservation through demand-side management (DSM) programs. While most of these programs are deemed to be cost effective, and therefore in the public interest, opportunities exist to improve cost effectiveness by targeting programs to those customers with the greatest potential for energy savings. This article details an analysis of three DSM programs offered by three Florida municipal electric utilities to explore such opportunities. First, we estimate programs’ energy savings impacts; second, we measure and compare energy savings across subgroups of program participants as determined by their pre-intervention energy performance, and third, we explore potential changes in program impacts that might be realized by targeting specific customers for participation in the DSM programs. All three programs resulted in statistically significant average (per-participant) energy savings, yet average savings varied widely, with the customers who performed best (i.e., most efficient) before the intervention saving the least energy and those who performed worst (i.e., least efficient) before the intervention saving the most. Assessment of alternative program participation scenarios with varying levels of customer targeting suggests that program impacts could be increased by as much as 80% for a professional energy audit program, just over 100% for a high-efficiency heat pump upgrade program, and nearly 250% for an attic insulation

    Activities in five major areas were undertaken during the WRIP: experiments using PNL-developed bend-over-sheave fatigue test machines to generate data on which to base a model for predicting large-diameter rope performance from that of small-diameter ropes; bend-over-sheave fatigue testing to determine differences in rope failure rates at varying rope loads; analyses to determine how wire ropes actually fail; development of a load sensor to record and quantity operational loads on drag and hoist ropes; and technology transfer activities to disseminate useful program findings to coal mine operators. Data obtained during the 6-year program support are included. High loads on wire ropes are damaging. As an adjunct, however, potentially useful countermeasures to high loads were identified. Large-diameter rope bend-over-sheave performance can be predicted from small-diameter rope test behavior, over some ranges.

    2010-01-01

    Background Current methods of selecting future residents for anesthesiology training programs do not adequately distinguish those who will succeed from the pool of seemingly well-qualified applicants. Some residents, despite high exam scores, may struggle in the OR in stressful situations. Aims This study examined whether specific neuropsychological and personality measures can distinguish high competency residents from low competency residents to aid in resident selection. Methods 25 residents enrolled in an anesthesiology program at a major academic institution were identified for participation. 13 were evaluated identified as “high competency” residents and 12 as “low competency ” by the department's clinical competency committee. Groups were evaluated on measures of fine motor dexterity, executive functioning, processing speed, attention, and personality using IPIP-NEO. Results There were no significant differences between groups on measures of fine-motor dexterity, executive functioning, processing speed, or attention. High competency residents scored significantly higher than low competency residents on measures of cooperation, self-efficacy, and adventurousness, and lower on measures of neuroticism, anxiety, anger, and vulnerability. Conclusion Although measures of fine-motor dexterity, executive functioning, processing speed, and attention do not appear to distinguish between high- and low competency residents in anesthesiology, specific personality characteristics may be associated with future success in an anesthesiology training program.

    Physicians are often insufficiently trained in bedside teaching and mentoring skills. To develop, implement and assess a simulation-based training program designed to improve clinical teaching among physicians. We developed a one-day tutor training program based on six simulated scenarios with video-based debriefing. The program's efficacy was assessed using questionnaires completed by the participating physicians and their students. Main outcome measures were self-perceived teaching skills at baseline, after participation in the program, and following completion of the tutor role. Secondary outcome measures were the students' perceptions regarding their tutor skills. Thirty-two physicians (mean age 35.5 years, 56% females) participated in the program. Self-assessment questionnaires indicated statistically significant improvement following the program in 13 of 20 measures of teaching skills. Additional improvement was observed upon completion of the tutor role, leading to significant improvement in 19 of the .20 measures. Questionnaires completed by their students indicated higher scores in all parameters as compared to a matched control group of tutors who did not participate in the program, though not statistically significant. Most participants stated that the program enhanced their teaching skills (88%), they implement program-acquired skills when teaching students (79%), and they would recommend it to their peers (100%). Satisfaction was similar among participants with and without previous teaching experience. A novel one-day simulation-based tutor training program was developed and implemented with encouraging results regarding its potential to improve clinical teaching and mentoring skills.

    This article aims to describe continuous quality improvement (CQI) for substance abuse prevention and treatment programs in a community-based organization setting. CQI (e.g., plan-do-study-act cycles (PDSA)) applied in healthcare and industry was adapted for substance abuse prevention and treatment programs in a community setting. The authors assessed the resources needed, acceptability and CQI feasibility for ten programs by evaluating CQI training workshops with program staff and a series of three qualitative interviews over a nine-month implementation period with program participants. The CQI activities, PDSA cycle progress, effort, enthusiasm, benefits and challenges were examined. Results indicated that CQI was feasible and acceptable for community-based substance abuse prevention and treatment programs; however, some notable resource challenges remain. Future studies should examine CQI impact on service quality and intended program outcomes. The study was conducted on a small number of programs. It did not assess CQI impact on service quality and intended program outcomes. Practical implications- This project shows that it is feasible to adapt CQI techniques and processes for community-based programs substance abuse prevention and treatment programs. These techniques may help community-based program managers to improve service quality and achieve program outcomes. This is one of the first studies to adapt traditional CQI techniques for community-based settings delivering substance abuse prevention and treatment programs.

    Nutrition interventions can alleviate the burden of malnutrition by improving patient outcomes; however, evidence on the economic impact of medical nutrition intervention remains limited. A previously published nutrition-focused quality improvement program targeting malnourished hospitalized patients showed that screening patients with a validated screening tool at admission, rapidly administering oral nutritional supplements, and educating patients on supplement adherence result in significant reductions in 30-day unplanned readmissions and hospital length of stay. To assess the potential cost-savings associated with decreased 30-day readmissions and hospital length of stay in malnourished inpatients through a nutrition-focused quality improvement program using a web-based budget impact model, and to demonstrate the clinical and fiscal value of the intervention. The reduction in readmission rate and length of stay for 1269 patients enrolled in the quality improvement program (between October 13, 2014, and April 2, 2015) were compared with the pre-quality improvement program baseline and validation cohorts (4611 patients vs 1319 patients, respectively) to calculate potential cost-savings as well as to inform the design of the budget impact model. Readmission rate and length-of-stay reductions were calculated by determining the change from baseline to post-quality improvement program as well as the difference between the validation cohort and the post-quality improvement program, respectively. As a result of improved health outcomes for the treated patients, the nutrition-focused quality improvement program led to a reduction in 30-day hospital readmissions and length of stay. The avoided hospital readmissions and reduced number of days in the hospital for the patients in the quality improvement program resulted in cost-savings of $1,902,933 versus the pre-quality improvement program baseline cohort, and $4,896,758 versus the pre-quality improvement program in the

    KENO IV is a multigroup Monte Carlo criticality program written for the IBM 360 computers. It executes rapidly and is flexibly dimensioned so the allowed size of a problem (i.e., the number of energy groups, number of geometry cards, etc., are arbitrary) is limited only by the total data storage required. The input data, with the exception of cross sections, fission spectra and albedos, may be entered in free form. The geometry input is quite simple to prepare and complicated three-dimensional systems can often be described with a minimum of effort. The results calculated by KENO IV include k-effective, lifetime and generation time, energy-dependent leakages and absorptions, energy- and region-dependent fluxes and region-dependent fission densities. Criticality searches can be made on unit dimensions or on the number of units in an array. A summary of the theory utilized by KENO IV, a section describing the logical program flow, a compilation of the error messages printed by the code and a comprehensive data guide for preparing input to the code are presented. 14 references

  8. ALTERNATIVES TO IMPROVE HYBRIDIZATION EFFICIENCY IN Eucalyptus BREEDING PROGRAMS

    Full Text Available Simple and quick hybridization procedures and ways to keep pollen grains viable for long periods are sought in plant breeding programs to provide greater work flexibility. The presentstudy was carried out to assess the efficiency of pollinations made shortly after flower emasculationand the viability of stored pollen from Eucalyptus camaldulensis and Eucalyptus urophylla clones cultivated in Northwestern Minas Gerais State. Controlled pollinations were carried out at zero, one,three, five and seven days after emasculation. Hybridization efficiency was assessed by thepercentage of viable fruits, number of seeds produced per fruit, percentage of viable seeds and also bycytological observation of the pollen development along the style. Flower buds from clones of the twospecies were collected close to anthesis to assess the viability of pollen grain storage. Pollen was thencollected and stored in a freezer (-18oC for 1, 2 and 3 months. Pollen assessed was carried out by invitro and in vivo germination tests. The efficiency of the pollinations varied with their delay and alsobetween species. The greatest pollination efficiency was obtained when they were carried out on thethird and fifth day after emasculation, but those performed simultaneously with emasculationproduced enough seeds to allow this practice in breeding programs. The decrease in pollen viabilitywith storage was not sufficiently significant to preclude the use of this procedure in artificialhybridization.

    The American College of Surgeons National Surgical Quality Improvement Program is well recognized in surgical quality measurement and is used widely in research. Recent calls to make it a platform for national public reporting and pay-for-performance initiatives highlight the importance of understanding which types of hospitals elect to participate in the program. Our objective was to compare characteristics of hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program to characteristics of nonparticipating US hospitals. The 2013 American Hospital Association and Centers for Medicare & Medicaid Services Healthcare Cost Report Information System datasets were used to compare characteristics and operating margins of hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program to those of nonparticipating hospitals. Of 3,872 general medical and surgical hospitals performing inpatient surgery in the United States, 475 (12.3%) participated in the American College of Surgeons National Surgical Quality Improvement Program. Participating hospitals performed 29.0% of all operations in the United States. Compared with nonparticipating hospitals, American College of Surgeons National Surgical Quality Improvement Program hospitals had a higher mean annual inpatient surgical case volume (6,426 vs 1,874; P quality-related accreditations (P Quality Improvement Program had established surgical quality improvement collaboratives. The American College of Surgeons National Surgical Quality Improvement Program hospitals are large teaching hospitals with more quality-related accreditations and financial resources. These findings should be considered when reviewing research studies using the American College of Surgeons National Surgical Quality Improvement Program data, and the findings reinforce that efforts are needed to facilitate participation in surgical quality improvement by all

    Background Antiretroviral treatment (ART) for HIV-positive patients has expanded rapidly in Asia over the last ten years. Our study aimed to describe the time trends and risk factors for overall survival in patients receiving first-line ART in Asia. Methods We included HIV-positive adult patients who initiated ART between 2003–2013 (n=16 546), from seven sites across six Asia-Pacific countries. Patient follow-up was to May 2014. We compared survival for each country and overall by time period of ART initiation using Kaplan-Meier curves. Factors associated with mortality were assessed using Cox regression, stratified by site. We also summarized first-line ART regimens, CD4 count at ART initiation, and CD4 and HIV viral load testing frequencies. Results There were 880 deaths observed over 54 532 person-years of follow-up, a crude rate of 1.61 (1.51, 1.72) per 100 person-years. Survival significantly improved in more recent years of ART initiation. The survival probabilities at 4 years follow-up for those initiating ART in 2003–05 was 92.1%, 2006–09 was 94.3% and 2010–2013 was 94.5% (pAsia have improved survival in more recent years of ART initiation.

    Nutritionally adequate complementary foods made from locally available ingredients are of high priority in developing countries, including Ghana. The majority of complementary foods in these countries are cereal-based and are unable to meet the nutrient intakes recommended by the World Health Organization. To evaluate the nutrient content and protein quality of local cereal-legume blends for complementary foods against recommendations and to determine the quantities of additional ingredients required to meet needs by using linear programming. Nine cereal-legume combinations (maize, sorghum, or millet combined with cowpea, peanut, or soybean) and koko (a traditional Ghanaian maize-based complementary food) were evaluated based on the macronutrient targets for a daily ration of complementary food for the age group 12 to 24 months: 264 kcal, 6.5 g of protein, and 8.2 to 11.7 g of fat. Protein quality was assessed by the Protein Digestibility Corrected Amino Acid Score (PDCAAS). Linear programming was then used to determine the amounts of additional oil, sugar, and lysine needed to meet macronutrient requirements. No traditional cereal-legume food met all complementary food macronutrient requirements on its own. Cereal-legume blends made with peanut or cowpeas were low in quality protein, while those with soybean were low in fat. Lysine was the limiting amino acid (PDCAAS 0.50 to 0.82) in all blends. Adding lysine increased utilizable protein by 1% to 10% in soybean blends, 35% to 40% in peanut blends, and 14% to 24% in cowpea blends. Peanut-maize, peanut-millet, and all soybean-cereal blends were able to meet macronutrient targets; most micronutrients remained below recommended levels. Traditional cereal-legume blends made from locally available ingredients do not meet energy, quality protein, and fat recommendations for complementary foods; however, such complementary food blends may be optimized to meet nutrient requirements by using linear programming as a tool to

    The objectives of this study were to assess the influence of green manure legumes and N fertilizer on soil microbial biomass and activities in rice (Oryza sativa) -wheat (Triticum aestivum) system. Soil samples (0-15 cm) were collected from field experiment established in 2001 involving mungbean (Vigna radiata), cowpea (Vigna unguiculata), soybean (Glycine max), sesbania (Sesbania rostrata), pigeonpea (Cajanus cajan) and guar (Cyamopsis tetragonoloba) as green manure in rice-wheat system in Peshawar valley, Pakistan. The results showed that the green manure legumes and N fertilizer application significantly increased the microbial biomass and activities in rice-wheat system. The average improvement gained from the green manure legumes relative to (fallow-based-rice-wheat) FRW, was 1.79 times for microbial activities, 1.70 times for microbial biomass-C (MBC), 1.49 times for microbial biomass-N (MBN), 1.82 times for C mineralization, 1.92 times for N mineralization, 3.36 times for bacterial population and 1.46 times for fungal population. The average improvement gained from N fertilizer (+N) relative to no N unfertilizer (0N), was 1.40 times for microbial activities, 1.17 times for MBC, 1.29 times for MBN, 1.42 times for C mineralization, 1.45 times for N mineralization, 1.17 times for bacterial population and 1.42 times for fungal population. Our results thus suggest that the microbiological attributes proved to be highly responsive and sensitive to the beneficial influence of green manure legumes in rice-wheat system and can be used as indicator of soil quality.

    Screening of immunization status at each health care encounter is recommended to improve immunization coverage rates but is often limited to primary care practices. A pilot intervention study was performed to ascertain the immunization status of hospitalized children and determine if development of an immunization plan before discharge would improve the vaccination status for such children. On the basis of power calculations estimated to detect an increase in immunization status from 60% to 70% with 80% power, 356 randomly selected children were enrolled between March 6, 2012 and June 14, 2012. Immunization records were obtained, immunization status determined, and parent/guardian informed if catch-up dose(s) were needed. If parent requested vaccine dose(s), they were administered before discharge. Vaccination status was current per Advisory Committee on Immunization Practices guidelines in 73% of hospitalized children, and 27% children required catch-up dose(s) (200 doses for 95 children). Human papilloma virus vaccine (dose 1), varicella zoster vaccine (dose 2), and meningococcal conjugate vaccine were the most commonly identified dose(s) needed. Of those requiring catch-up dose(s), 25% were caught up, increasing vaccination status to 80% at 1-month post hospital discharge. This is the first study to determine the immunization status of hospitalized pediatric patients of all ages, including adolescents, providing new data on the immunization status of the inpatient pediatric population. A pilot intervention consisting of obtaining immunization records, determining immunization status, and discussing catch-up dose(s) before discharge resulted in improvement of immunization status, suggesting that the inpatient setting may be used along with many other national strategies to help address missed vaccination opportunities.

ABSTRACT Limestone mining using open pit mining method that involves vegetation removal and soil drilling and blasting in accessing limestone material has caused ecosystem damages. Natural recovery of such a harsh site is a slow process as the site condition in the successional process do not favor the natural vegetation development. Plants Establishment could facilitate other plants by ameliorating harsh environmental characteristics and/or increasing the availability of nutrient resources. Facilitation impact of legume cover crop (Centrosema pubescens and mycorrhizal-inoculated plantation (Vitex cofassus was studied on primary succession of TNS limestone mining quarry. The emergence of natural plants is measured using individual density, diversity and number of species by quadrat systematic plot method base on their habitus. Site conditions measured by litterfall thickness and biomass, soil organic matter content and soil organic carbon levels. The study was conducted in four types of areas on limestone postmining lands are open areas/natural conditions without planting, legume cover crop area, non mycorrhizal-inoculated plant area and mycorrhizal-inoculated plant area. The results indicated, establishment of legume cover crops and mycorrhizal-inoculated plants improved site conditions of limestone quarry. Legume cover crops establishment produced a large amount of litters with 1.08 cm of a thickness and 188.96 g/m2 of biomass, and it’s subsequent decomposition increased soil organic matter of 3.80% and the organic carbon content of 2.20%. Plantation formation gave similar impact as well, particulary those inoculated with Arbuscula Mycorrhizae Fungi (AMF produced amount of litters with 1.32 cm of a thickness and 220.48 g/m2 of biomass, with 3

    distribution, the impact of pests and diseases, as well as vulnerability to poor soils, drought and other effects of climate change. This chapter summarises data from over 50 field experiments undertaken since 2001 on cereal-grain legume intercropping in 13 sites in southern and western France as well...... as in Denmark using spring and winter cereal-grain legume intercrops. Intercropping involves simultaneously growing two or more crops in the same field for a significant period of time. The practice is ancient as early records from many human societies all over the world have shown. Intercropping systems...... are estimated to still provide as much as 15–20% of the world’s food supply. The practice was widespread in some European farming systems up until the 1950s – before the so-called fossilisation of agriculture. At that time as much as 50 % of all available nitrogen (N) may have originated from symbiotic N2...

  19. Rhizobium-legume symbioses: the crucial role of plant immunity.

    Gourion, Benjamin; Berrabah, Fathi; Ratet, Pascal; Stacey, Gary

    2015-03-01

    New research results have significantly revised our understanding of the rhizobium-legume infection process. For example, Nod factors (NFs), previously thought to be absolutely essential for this symbiosis, were shown to be dispensable under particular conditions. Similarly, an NF receptor, previously considered to be solely involved in symbiosis, was shown to function during plant pathogen infections. Indeed, there is a growing realization that plant innate immunity is a crucial component in the establishment and maintenance of symbiosis. We review here the factors involved in the suppression of plant immunity during rhizobium-legume symbiosis, and we attempt to place this information into context with the most recent and sometimes surprising research results.

    Full Text Available Grasslands afforestation aims at adding different soil uses in a way they become profitable for their owners. As such handling aims at minimizing impacts, the current study had as its goal the use of soil macrofauna in order to evaluate legume afforestation effects on the soil, regardless the depth. Thus, nitrogen fixing species were inserted onto grassland areas and the macrofauna collection was performed 6 years after their planting in the 0-10cm, 10-20cm and 20.30cm layers, in winter and summer. Leguminous influence was different between depths and times of the year. It mostly favors communities under "Mimosa" Genus treetops. Besides, the effects from climatic seasonal variations on invertebrates were mitigated by the implementation of such legume trees

    Morales-Medina, Rocío; Del Mar Muñío, María; Guadix, Emilia M; Guadix, Antonio

    2014-01-30

    Resistant starch (RS) was produced by enzymatic hydrolysis of flours from five different legumes: lentil, chickpea, faba bean, kidney bean and red kidney bean. Each legume was firstly treated thermally, then hydrolyzed with pullulanase for 24h at 50°C and pH 5 and lyophilized. At the end of each hydrolysis reaction, the RS amount ranged from 4.7% for red kidney beans to 7.5% for chickpeas. With respect to the curves of RS against hydrolysis time, a linear increase was observed initially and a plateau was generally achieved by the end of reaction. These curves were successfully modeled by a kinetic equation including three parameters: initial RS, RS at long operation time and a kinetic constant (k). Furthermore, the relative increase in hydrolysis, calculated using the kinetic parameters, was successfully correlated to the percentage of amylose. Copyright © 2013 Elsevier Ltd.

    For the past 15 years, Computer Sciences Corporation (CSC) has participated in a process improvement program as a member of the Software Engineering Laboratory (SEL), which is sponsored by GSFC. The benefits CSC has derived from involvement in this program are analyzed. In the environment studied, it shows that improvements were indeed achieved, as evidenced by a decrease in error rates and costs over a period in which both the size and the complexity of the developed systems increased substantially. The principles and mechanics of the process improvement program, the lessons CSC has learned, and how CSC has capitalized on these lessons are also discussed.

    This study aims to determine the influence of reading comprehension skills of English for PGSD students through the application of SQ3R learning method. The type of this research is Pre-Experimental research because it is not yet a real experiment, there are external variables that influence the formation of a dependent variable, this is because there is no control variable and the sample is not chosen randomly. The research design is used is one-group pretest-post-test design involving one group that is an experimental group. In this design, the observation is done twice before and after the experiment. Observations made before the experiment (O1) are called pretests and the post-experimental observation (O2) is called posttest. The difference between O1 and O2 ie O2 - O1 is the effect of the treatment. The results showed that there was an improvement in reading comprehension skills of PGSD students in Class M.4.3 using SQ3R method, and better SQ3R enabling SQ3R to improve English comprehension skills.

    2018-02-27

    The root nodule symbiosis established between legumes and rhizobia is an exquisite biological interaction responsible for fixing a significant amount of nitrogen in terrestrial ecosystems. The success of this interaction depends on the recognition of the right partner by the plant within the richest microbial ecosystems on Earth, the soil. Recent metagenomic studies of the soil biome have revealed its complexity, which includes microorganisms that affect plant fitness and growth in a beneficial, harmful, or neutral manner. In this complex scenario, understanding the molecular mechanisms by which legumes recognize and discriminate rhizobia from pathogens, but also between distinct rhizobia species and strains that differ in their symbiotic performance, is a considerable challenge. In this work, we will review how plants are able to recognize and select symbiotic partners from a vast diversity of surrounding bacteria. We will also analyze recent advances that contribute to understand changes in plant gene expression associated with the outcome of the symbiotic interaction. These aspects of nitrogen-fixing symbiosis should contribute to translate the knowledge generated in basic laboratory research into biotechnological advances to improve the efficiency of the nitrogen-fixing symbiosis in agronomic systems.

    Increasing the level of starch that is not digested by the end of the small intestine and therefore enters the colon ('resistant starch') is a major opportunity for improving the nutritional profile of foods. One mechanism that has been shown to be successful is entrapment of starch within an intact plant tissue structure. However, the level of tissue intactness required for resistance to amylase digestion has not been defined. In this study, intact cells were isolated from a range of legumes after thermal treatment at 60 °C (starch not gelatinised) or 95 °C (starch gelatinised) followed by hydrolysis using pancreatic alpha amylase. It was found that intact cells, isolated at either temperature, were impervious to amylase. However, application of mechanical force damaged the cell wall and made starch accessible to digestive enzymes. This shows that the access of enzymes to the entrapped swollen starch is the rate limiting step controlling hydrolysis of starch in cooked legumes. The results suggest that a single cell wall could be sufficient to provide an effective delivery of starch to the large intestine with consequent nutritional benefits, provided that mechanical damage during digestion is avoided.

    Evidence of the impact of homestead food production programs on nutrition outcomes such as anemia and growth is scant. In the absence of information on program impact pathways, it is difficult to understand why these programs, which have been successful in increasing intake of micronutrient-rich foods, have had such limited documented impact on nutrition outcomes. To conduct a process evaluation of Helen Keller International's (HKI's) homestead food production program in Cambodia to assess whether the program was operating as planned (in terms of design, delivery, and utilization) and to identify ways in which the program might need to be strengthened in order to increase its potential for impact. A program theory framework, which laid out the primary components along the hypothesized program impact pathways, was developed in collaboration with HKI and used to design the research. Semistructured interviews and focus group discussions with program beneficiaries (n = 36 and 12, respectively), nonbeneficiaries (n = 12), and program implementers (n = 17 and 2, respectively) and observations of key program delivery points, including health and nutrition training sessions (n = 6), village model farms (n = 6), and household gardens of beneficiaries (n = 36) and nonbeneficiaries (n = 12), were conducted to assess the delivery and utilization of the primary program components along the impact pathways. The majority of program components were being delivered and utilized as planned. However, challenges with some of the key components posited to improve outcomes such as anemia and growth were noted. Among these were a gap in the expected pathway from poultry production to increased intake of eggs and poultry meat, and some weaknesses in the delivery of the health and nutrition training sessions and related improvements in knowledge among the village health volunteers and beneficiaries. Although the program has been successful in delivering the majority of the program

  9. Improving the Held and Karp Approach with Constraint Programming

    Science.gov (United States)

    Benchimol, Pascal; Régin, Jean-Charles; Rousseau, Louis-Martin; Rueher, Michel; van Hoeve, Willem-Jan

    Held and Karp have proposed, in the early 1970s, a relaxation for the Traveling Salesman Problem (TSP) as well as a branch-and-bound procedure that can solve small to modest-size instances to optimality [4, 5]. It has been shown that the Held-Karp relaxation produces very tight bounds in practice, and this relaxation is therefore applied in TSP solvers such as Concorde [1]. In this short paper we show that the Held-Karp approach can benefit from well-known techniques in Constraint Programming (CP) such as domain filtering and constraint propagation. Namely, we show that filtering algorithms developed for the weighted spanning tree constraint [3, 8] can be adapted to the context of the Held and Karp procedure. In addition to the adaptation of existing algorithms, we introduce a special-purpose filtering algorithm based on the underlying mechanisms used in Prim's algorithm [7]. Finally, we explored two different branching schemes to close the integrality gap. Our initial experimental results indicate that the addition of the CP techniques to the Held-Karp method can be very effective.

    Out-of-reactor experiments and irradiations are being utilized to develop and demonstrate the efficacy of specific advanced fuel designs to improve FCI behavior. The advanced light water reactor fuel designs being evaluated combine annular pellets, graphite coating on the inner surface of the cladding, and helium pressurization. A sphere-pac fuel design is also being developed. Characterization of the graphite coatings includes studies of composition, application methods, thickness control, moisture control, thermal conductivity, compatibility with the zircaloy cladding, strain-to-failure, and friction and wear characteristics. Rods of the different fuel designs, as well as reference rods, are being irradiated in the Halden Boiling Water Reactor and the Big Rock Point Reactor to accumulate burnup prior to ramping tests

    In order to fully exploit the joint Chandra/JWST/HST ventures to detect faint sources, we urgently need an advanced matching algorithm between optical/NIR and X-ray catalogs/images. This will be of paramount importance in bridging the gap between upcoming optical/NIR facilities (JWST) and later X-ray ones (Athena, Lynx). We propose to develop an advanced and automated tool to improve the identification of Chandra X-ray counterparts detected in deep optical/NIR fields based on T-PHOT, a software widely used in the community. The developed code will include more than 20 years in advancements of X-ray data analysis and will be released to the public. Finally, we will release an updated catalog of X-ray sources in the CANDELS regions: a leap forward in our endeavor of charting the Universe.

  12. Tropical forage legumes for environmental benefits: An overview

    2018-01-01

    Full Text Available Ruminant livestock production in the tropics, particularly when based on pastures, is frequently blamed for being detrimental to the environment, allegedly contributing to: (1 degradation and destruction of ecosystems, including degradation and loss of soil, water and biodiversity; and (2 climate change (global warming. In this paper we argue that, rather than being detrimental, tropical forage legumes can have a positive impact on the environment, mainly due to key attributes that characterize the Leguminosae (Fabaceae family: (1 symbiotic nitrogen fixation; (2 high nutritive value; (3 deep-reaching tap-root system; (4 wide taxonomic and genetic diversity; and (5 presence of particular secondary metabolites. Although there are also potential negative aspects, such as soil acidification and the risks of introduced legumes becoming invasive weeds, we submit that legumes have potential to contribute significantly to sustainable intensification of livestock production in the tropics, along with the provision of ecosystem services. To further assess, document and realize this potential, research for development needs in a range of areas are indicated.

    The discovery of bioactive molecules from botanical sources is an expanding field, preferentially oriented to plants having a tradition of use in medicine and providing high yields and availability. Temperate forage legumes are Fabaceae species that include worldwide-important crops. These plants possess therapeutic virtues that have not only been used in veterinary and folk medicine, but have also attracted the interest of official medicine. We have examined here Medicago sativa (alfalfa), Trifolium pratense and T. repens (clovers), Melilotus albus and M. officinalis (sweet clovers), Lotus corniculatus (birdsfoot trefoil), Onobrychis viciifolia (sainfoin), Lespedeza capitata (roundhead lespedeza), and Galega officinalis (goat's rue). The phytochemical complexes of these species contain secondary metabolites whose pharmacological potentials deserve investigation. Major classes of compounds include alkaloids and amines, cyanogenic glycosides, flavonoids, coumarins, condensed tannins, and saponins. Some of these phytochemicals have been related to antihypercholesterolemia, antidiabetic, antimenopause, anti-inflammatory, antiedema, anthelmintic, and kidney protective effects. Two widely prescribed drugs have been developed starting from temperate forage legumes, namely, the antithrombotic warfarin, inspired from sweet clover's coumarin, and the antidiabetic metformin, a derivative of sainfoin's guanidine. Available evidence suggests that temperate forage legumes are a potentially important resource for the extraction of active principles to be used as nutraceuticals and pharmaceuticals.

    2007-01-01

    The Effects of irradiation (dose levels of 5, 7.5 and 10 kGy) on nutritive characteristics of peas (Pisum satinum L), cow peas (Vigna unguiculata L.Walp), lentils (Lens culinaris Med), kidney beans (Phaseolus vulgaris L), and chickpeas (Cicer arietinurn L) were examined. Analyses included proximate composition, levels of anti-nutrients (phytic acid, tannins), available lysine (AL), in vitro protein digestibility (IVPD), and protein efficiency ratio (PER) in the growing rat. The results showed that moisture, crude protein, crude fat, crude fiber, and ash were unchanged by the irradiation. Radiation processing significantly (p<0.05) reduced the levels of phytic acid (PA), tannins (TN), and available lysine (AE). IVPD and PER were significantly enhanced in a dose-dependent manner, relative to unirradiated control samples, for all legumes. The data sets for each legume exhibited high correlation coefficients between radiation dose and PA, TN, AE, IVPD, and PER. These results demonstrate the benefits of irradiation on the nutritional properties of these legumes

    The improved single shank high pressure turbine design was evaluated in component tests consisting of performance, heat transfer and mechanical tests, and in core engine tests. The instrumented core engine test verified the thermal, mechanical, and aeromechanical characteristics of the improved turbine design. An endurance test subjected the improved single shank turbine to 1000 simulated flight cycles, the equivalent of approximately 3000 hours of typical airline service. Initial back-to-back engine tests demonstrated an improvement in cruise sfc of 1.3% and a reduction in exhaust gas temperature of 10 C. An additional improvement of 0.3% in cruise sfc and 6 C in EGT is projected for long service engines.

    Full Text Available This research presented how to use a multi-thread programming technique to improve the performance of a program written by Windows Presentation Foundation (WPF. The Computer Assisted Instruction (CAI software, named GAME24, was selected to use as a case study. This study composed of two main parts. The first part was about design and modification of the program structure upon the Object Oriented Programing (OOP approach. The second part was about coding the program using the multi-thread technique which the number of threads were based on the calculated Catalan number. The result showed that the multi-thread programming technique increased the performance of the program 44%-88% compared to the single-thread technique. In addition, it has been found that the number of cores in the CPU also increase the performance of multithreaded program proportionally.

    2001-01-01

    Full Text Available While the warning systems do an increasingly good job of warning of all probable events, there are still apparent false alarms and a lack of magnitude prediction. History shows that major advances in technology occur when several components mature to be combined into a final system. An example is the communications satellite: around 1960, the silicon solar cell, the RF transistor, the integrated circuit, the large rocket, knowledge of the synchronous orbit, reliable components, and supporting systems came together to produce systems so workable that the early ones are still usable and the current ones just have more channels. We are now in a “1960 position” in tsunami work. Deep ocean sensors are in place, numerous tide gauges and sea level gauges are telemetered (via satellite, real-time numerical analysis programs are under development, Mw can now be calculated in an hour and Mwp in a minute, a global infrasonic network has been deployed, T-phase data are readily available, and so are ionospheric sounders. We have the capability to cheaply and quickly record, correlate, analyze, transmit, and discard data from all these sensor systems. Thus, we should have the means to develop the ability to evaluate a tsunamigenic earthquake and early tsunami waves, reliably and even quantitatively.I suggest the ideal way to accomplish this is to establish a small, dedicated laboratory which will bring together a selection of data from these sensor systems to evaluate every possible tsunamigenic event. It is now easy to temporarily store these data in volatile memory for analyses, retention, and discard. An earthquake that would be checked and discarded by the warning center can provide the trigger for storage and evaluation. Most of the data are low frequency, easy to transmit (part of it is on the Internet now, and store. Information on prior experiments with some of the components, current status, and processing estimates is provided, along with ample

    To enhance the achievement of a college of pharmacy's goals for education, research, and service missions by implementing an excellence program based on the Studer Group model for continuous quality improvement. The Studer model was combined with university strategic planning for a comprehensive quality-improvement program that was implemented over 5 years. The program included identifying and measuring key performance indicators, establishing specific "pillar" goals, aligning behaviors with goals and values, and training leaders. Assessment of key performance indicators over 5 years demonstrated progress toward achieving college goals for student and faculty satisfaction, research funding, numbers of students seeking formal postgraduate training, and private giving. Implementation of a continuous quality-improvement program based on the Studer program enabled the college to focus on and meet its yearly and strategic goals for all components of its mission.

    The silvopastoral system (SPS) has been suggested to ensure sustainability in animal production systems in tropical ecosystems. The objective of this study was to evaluate pasture characteristics, herbage intake, grazing activity and milk yield of Holstein×Zebu cows managed in two grazing systems (treatments): SPS dominated by a graminaceous forage (Brachiaria decumbens) intercropped with different leguminous herbaceous forages (Stylosanthes spp., Pueraria phaseoloides and Calopogonium mucunoides) and legume trees (Acacia mangium, Gliricidia sepium and Leucaena leucocephala), and open pasture (OP) of B. decumbens intercropped only with Stylosanthes spp. Pastures were managed according to the rules for organic cattle production. The study was carried out by following a switch back format with 12 cows, 6 for each treatment, over 3 experimental years. Herbage mass was similar (P>0.05) for both treatments, supporting an average stocking rate of 1.23 AU/ha. Daily dry matter intake did not vary (P>0.05) between treatments (average of 11.3±1.02 kg/cow per day, corresponding to 2.23±0.2% BW). Milk yield was higher (P0.05) in subsequent years. The highest (P0.05) milk yields. Low persistence of Stylosanthes guianensis was observed over the experimental period, indicating that the persistence of forage legumes under grazing could be improved using adapted cultivars that have higher annual seed production. The SPS and a diversified botanical composition of the pasture using legume species mixed with grasses are recommended for organic milk production.

    Quality improvement is a potential method to enhance employee satisfaction. This study describes the impact of a program instituted to enhance employee satisfaction using the principles of high-performing microsystems. A shared leadership committee, participatory meetings, suggestion boxes, and quality improvement projects were implemented as part of the program. A follow-up survey 1 year after implementation of the program demonstrated an increase in employee perception of the division's desire to improve service (16%), opportunities to expand skills (17%), involvement in work decisions (25%), and the institution's interest in employee well-being (17%). Key drivers of discretionary effort (4 of 5), job satisfaction (2 of 6), and overall satisfaction (1 of 8) with the institution showed statistically significant improvement in the study division as compared with the other divisions in which no such program was implemented. Further research is needed to study systems changes that enhance employee satisfaction and their impact on patient and financial outcomes.

    Full Text Available Microbial solubilisation of low soluble inorganic phosphates is an important process contributing for the phosphorus available to plants in tropical soils. This study evaluates the ability of inoculant strains for tropical legumes to solubilise inorganic phosphates of low solubility that are found in tropical soils. Seven strains of Leguminosae nodulating bacteria (LNB were compared with one another and with a non-nodulating positive control, Burkholderia cepacia (LMG 1222T. Four of the strains are used as inoculants for cowpeas (Vigna unguiculata (Bradyrhizobium sp. UFLA 03-84; Bradyrhizobium elkani INPA 03-11B and Bradyrhizobium japonicum BR3267 or for common beans (Phaseolus vulgaris (Rhizobium tropici CIAT 899T. Rhizobium etli UFLA 02-100 and Rhizobium leguminosarum 316C10a are also efficient nodulators of beans and Cupriavidus taiwanensis LMG 19424T nodulates on Mimosa pudica. Two experiments, with solid and liquid media, were performed to determine whether the strains were able to solubilise CaHPO4, Al(H2PO43 or FePO4.2H2O. On solid GELP medium none of the strains dissolved FePO4.2H2O, but LMG 1222, UFLA 03-84 and CIAT 899 solubilised CaHPO4 particularly well. These strains, along with LMG 19424 and BR 3267, were also able to increase the solubility of Al(H2PO43. In liquid GELP medium, LMG 1222 solubilised all phosphate sources, but no legume nodulating strain could increase the solubility of Al(H2PO43. The strains CIAT 899 and UFLA 02-100 were the only legume nodulating bacteria able to solubilise the other phosphate sources in liquid media, dissolving both CaHPO4 and FePO4.2H2O. There was a negative correlation between the pH of the culture medium and the concentration of soluble phosphate when the phosphorus source was CaHPO4 or FePO4.2H2O. The contribution of these strains to increasing the phosphorus nutrition of legumes and non-legume plant species should be investigated further by in vivo experiments.

    Full Text Available Functional properties such as protein solubility, swelling capacity, water holding capacity, gelling ability, bulk density and foaming capacity of flours of some commonly used cereals and legume (wheat, refined wheat, maize and chickpea and their blends were studied. Blends of flours were prepared by mixing equal proportions of selected floors. Statistically significant difference  in studied functional properties except bulk density was observed among cereal flours and their blends. Chickpea flour was found to possess comparatively high water holding capacity, protein solubility index and swelling capacity. The functional properties of maize and wheat flours were found to be improved when blended with chickpea. Chickpea flour and its blends with cereal flours were found to possess good functional score and suggested as favorable candidates for use in the preparation of viscous foods and bakery products. The data provide guidelines regarding the improvement in functional properties of economically favorable cereal flours.

    Full Text Available Jennifer Manlove, Heather Fish, Kristin Anderson Moore Child Trends, Bethesda, MD, USA Background: US adolescents have high rates of teen pregnancy, childbearing, and sexually transmitted infections (STIs, highlighting the need to identify and implement effective programs that will help improve teen sexual and reproductive health. Materials and methods: This review identified 103 random-assignment evaluations of 85 programs that incorporated intent-to-treat analyses and assessed impacts on pregnancy, childbearing, STIs, and their key determinants – sexual activity, number of sexual partners, condom use, and other contraceptive use – among teens. This review describes the evidence base for five broad program approaches, including abstinence education, comprehensive sex education, clinic-based programs, youth development programs, and parent–youth relationship programs. We also describe programs with impacts on key outcomes, including pregnancy/childbearing, STIs, and those that found impacts on both sexual activity and contraceptive use. Results: Our review identified 52 effective programs: 38 with consistent impacts on reproductive health outcomes, and 14 with mixed findings (across subpopulations, follow-ups, or multiple measures of a single outcome. We found that a variety of program approaches produced impacts on sexual and reproductive health outcomes. Parent–youth relationship programs and clinic-based program evaluations more frequently showed impacts than other program approaches, although we also identified a number of abstinence-education, comprehensive sex education, and youth-development programs with impacts on sexual and reproductive health outcomes. Overall, we identified nine program evaluations with impacts on teen pregnancies or births, five with impacts on reducing STIs, and 15 with impacts on both delaying/reducing sexual activity and increasing contraceptive use (including condom use. Conclusion: Future efforts should

    1984-01-01

    The metallurgical irradiation experiment at the Oak Ridge Research Reactor Poolside Facility (ORR-PSF) was designed as a benchmark to test the accuracy of radiation embrittlement predictions in the pressure vessel wall of light water reactors on the basis of results from surveillance capsules. The PSF metallurgical Blind Test is concerned with the simulated surveillance capsule (SSC) and the simulated pressure vessel capsule (SPVC). The data from the ORR-PSF benchmark experiment are the basis for comparison with the predictions made by participants of the metallurgical ''Blind Test''. The Blind Test required the participants to predict the embrittlement of the irradiated specimen based only on dosimetry and metallurgical data from the SSC1 capsule. This exercise included both the prediction of damage fluence and the prediction of embrittlement based on the predicted fluence. A variety of prediction methodologies was used by the participants. No glaring biases or other deficiencies were found, but neither were any of the methods clearly superior to the others. Closer analysis shows a rather complex and poorly understood relation between fluence and material damage. Many prediction formulas can give an adequate approximation, but further improvement of the prediction methodology is unlikely at this time given the many unknown factors. Instead, attention should be focused on determining realistic uncertainties for the predicted material changes. The Blind Test comparisons provide some clues for the size of these uncertainties. In particular, higher uncertainties must be assigned to materials whose chemical composition lies outside the data set for which the prediction formula was obtained. 16 references, 14 figures, 5 tables

    Quality improvement (QI) programs are frequently implemented to support primary healthcare (PHC) team development and to improve care outcomes. In Ontario, Canada, the Quality Improvement and Innovation Partnership (QIIP) offered a learning collaborative (LC) program to support the development of interdisciplinary team function and improve chronic disease management, disease prevention, and access to care. A qualitative study using a phenomenological approach was conducted as part of a mixed-method evaluation to explore the influence of the program on team functioning in participating PHC teams. A purposive sampling strategy was used to identify PHC teams (n = 10), from which participants of different professional roles were selected through a purposeful recruitment process to reflect maximum variation of team roles. Additionally, QI coaches working with the interview participants and the LC administrators were also interviewed. Data were collected through semistructured telephone interviews that were audiotaped and transcribed verbatim. Thematic analysis was conducted through an iterative and interpretive approach. The shared experience of participating in the program appeared to improve team functioning. Participants described increased trust and respect for each other's clinical and administrative roles and were inspired by learning about different approaches to interdisciplinary care. This appeared to enhance collegial relationships, collapse professional silos, improve communication, and increase interdisciplinary collaboration. Teamwork involves more than just physically grouping healthcare providers from multiple disciplines and mandating them to work together. The LC program provided opportunities for participants to learn how to work collaboratively, and participation in the LC program appeared to enhance team functioning.

    Airway management is a critical skill for air medical providers, including the use of rapid sequence intubation (RSI) medications. Mediocre success rates and a high incidence of complications has challenged air medical providers to improve training and performance improvement efforts to improve clinical performance. The aim of this research was to describe the experience with a novel, integrated advanced airway management program across a large air medical company and explore the impact of the program on improvement in RSI success. The Helicopter Advanced Resuscitation Training (HeART) program was implemented across 160 bases in 2015. The HeART program includes a novel conceptual framework based on thorough understanding of physiology, critical thinking using a novel algorithm, difficult airway predictive tools, training in the optimal use of specific airway techniques and devices, and integrated performance improvement efforts to address opportunities for improvement. The C-MAC video/direct laryngoscope and high-fidelity human patient simulation laboratories were implemented during the study period. Chi-square test for trend was used to evaluate for improvements in airway management and RSI success (overall intubation success, first-attempt success, first-attempt success without desaturation) over the 25-month study period following HeART implementation. A total of 5,132 patients underwent RSI during the study period. Improvements in first-attempt intubation success (85% to 95%, p improving RSI intubation performance in a large air medical company.

    Transcription factors are DNA binding proteins that regulate gene expression. The nitrogen fixing symbiosis established between legume plants and soil bacteria is a complex interaction, in which plants need to integrate signals derived from the symbiont and the surrounding environment to initiate the developmental program of nodule organogenesis and the infection process. Several transcription factors that play critical roles in these processes have been reported in the past decade, including proteins of the GRAS and NF-Y families. Recently, we reported the characterization of a new GRAS domain containing-protein that interacts with a member of the C subunit of the NF-Y family, which plays an important role in nodule development and the progression of bacterial infection during the symbiotic interaction. The connection between transcription factors of these families highlights the significance of multimeric complexes in the fabulous capacity of plants to integrate and respond to multiple environmental stimuli.

  6. Genomic resources in mungbean for future breeding programs

    Full Text Available Among the legume family, mungbean (Vigna radiata has become one of the important crops in Asia, showing a steady increase in global production. It provides a good source of protein and contains most notably folate and iron. Beyond the nutritional value of mungbean, certain features make it a well-suited model organism among legume plants because of its small genome size, short life-cycle, self-pollinating, and close genetic relationship to other legumes. In the past, there have been several efforts to develop molecular markers and linkage maps associated with agronomic traits for the genetic improvement of mungbean and, ultimately, breeding for cultivar development to increase the average yields of mungbean. The recent release of a reference genome of the cultivated mungbean (V. radiata var. radiata VC1973A and an additional de novo sequencing of a wild relative mungbean (V. radiata var. sublobata has provided a framework for mungbean genetic and genome research, that can further be used for genome-wide association and functional studies to identify genes related to specific agronomic traits. Moreover, the diverse gene pool of wild mungbean comprises valuable genetic resources of beneficial genes that may be helpful in widening the genetic diversity of cultivated mungbean. This review paper covers the research progress on molecular and genomics approaches and the current status of breeding programs that have developed to move toward the ultimate goal of mungbean improvement.

  7. Activation of cell divisions in legume nodulation

    DEFF Research Database (Denmark)

    Nadzieja, Marcin

    Leguminous plants engage into symbiotic relationships with soil bacteria, rhizobia, and develop root nodules. This process initiates with recognition of bacteria derived signalling molecules called nod factors. The subsequent events lead to symbiotic infection and, occurring in parallel, de novo...... was shown to require auxin signalling. Cytokinin, in contrast, exert a negative regulation of bacterial entry into the root. During organogenesis, auxin and cytokinin maxima are known to accompany nodule primordia development and together regulate progression through the cell cycle. Moreover, application...... the two hormones require further investigation. In order to improve understanding in these areas we aimed to develop and characterise hormone and cell division markers in Lotus japonicus. Using the extensive genetic resources available in L. japonicus, these markers may then be used to develop a more...

    Bokov, Dmitry; Byers, Kenneth R.

    2004-01-01

    As the Russian State regulatory agency responsible for oversight of nuclear material control and accounting (MC and A), Gosatomnadzor of Russia (GAN) determines the status of the MC and A programs at Russian facilities. Last year, GAN developed and implemented their Nuclear Material Measurement Program Plan which documents current non-destructive assay (NDA) measurement capability in all regions of GAN; provides justification for upgrades to equipment, procedures and training; and defines the inspector-facility operator interface as it relates to NDA measurement equipment use. This Program Plan has helped to give the GAN inspection measurements more legal and official status as an oversight tool, and has also helped to improve other GAN MC and A oversight activities. These improvements include developing a tamper-indicating device program, conducting NDA workshops at specific Russian nuclear facilities to better train MC and A inspectors, and developing training evaluation programs. The Program is an important tool to address the GAN role in oversight of the Russian Federal Information System nuclear material database. This paper describes the feedback received from the GAN regional offices on the implementation of the Program Plan during its first year in operation and how the Program Plan has affected other GAN inspection activities to improve MC and A oversight.

    2013-01-01

    In response to increasing abuse of prescription drugs, 44 states have implemented -- and five more states will soon adopt -- monitoring programs to track prescriptions of controlled medications. Although these programs are primarily designed to help law enforcement officials and regulatory agencies spot possible illegal activity, health care providers have begun to use data from them to help improve patient safety and quality of care. We reviewed government documents, expert white papers, articles from the peer reviewed medical literature, and reports of the experiences of local health officials. Although we found some evidence that prescription drug monitoring programs are a benefit to both law enforcement and health care delivery, the programs have strengths and weaknesses, and their overall impact on drug abuse and illegal activity remains unclear. We believe that improving the efficacy of prescription drug monitoring programs will require such changes as more standardization and interstate cooperation, better training of providers, more secure funding, and further evaluation.

    : Employee wellness programs can provide benefits to institutions as well as employees and their families. Despite the attempts of some organizations to implement programs that take a holistic approach to improve physical, mental, and social wellness, the most common programs are exclusively comprised of physical and nutritional components. In this study, we implemented a wellness program intervention, including training, directed at middle managers in several multinational organizations. We included control and experimental groups to measure wellness and teamwork with two repeated measures. Our results indicated that employees receiving the intervention had improved measures of wellness and teamwork. A positive relationship was found between wellness and teamwork in the experimental group when compared to the control group. Taken together, the data suggest that implementation of these programs would provide valuable outcomes for both employees and organizations.

    Natural resource managers are often expected to achieve both environmental protection and economic development even when there are fundamental trade-offs between these goals. Adaptive management provides a theoretical structure for program administrators to balance social priorities in the presence of trade-offs and to improve conservation targeting. We used the case of Mexico's federal Payments for Hydrological Services program (PSAH) to illustrate the importance of adaptive management for improving program targeting. We documented adaptive elements of PSAH and corresponding changes in program eligibility and selection criteria. To evaluate whether these changes resulted in enrollment of lands of high environmental and social priority, we compared the environmental and social characteristics of the areas enrolled in the program with the characteristics of all forested areas in Mexico, all areas eligible for the program, and all areas submitted for application to the program. The program successfully enrolled areas of both high ecological and social priority, and over time, adaptive changes in the program's criteria for eligibility and selection led to increased enrollment of land scoring high on both dimensions. Three factors facilitated adaptive management in Mexico and are likely to be generally important for conservation managers: a supportive political environment, including financial backing and encouragement to experiment from the federal government; availability of relatively good social and environmental data; and active participation in the review process by stakeholders and outside evaluators. © 2014 Society for Conservation Biology.

  17. Strategies and policies for improving energy efficiency programs: Closing the loop between evaluation and implementation

    International Nuclear Information System (INIS)

    Vine, Edward

    2008-01-01

    Program implementers often use evaluation results to improve the performance of their programs, but, as described in this paper, this is not always the case. Based on a review of the literature, participation in workshops, and interviews with over 50 program implementers, evaluators, and regulators in the United States and Canada, the utilization of evaluation results is investigated by asking the following questions: (1) How are program evaluation results used by program implementers and other stakeholders? (2) How are program evaluation results communicated to program implementers and other stakeholders? (3) Are the needs of program implementers being met by program evaluation? (4) What is the role of the utility regulator in facilitating the use of program evaluation results? (5) What other mechanisms can facilitate the use of program evaluation results? While there is some consensus on the answers to these questions, the type of interest in and use of evaluation varies by functional role (e.g., evaluator versus implementer), maturity of the energy efficiency market, institutional context (e.g., evaluation and implementation conducted inside the same organization, or evaluation and implementation conducted by separate entities), and by regulatory demands and evaluation interests

    Understanding how and why programs work-not simply whether they work-is crucial. Good theory is indispensable to advancing the science of improvement. We argue for the usefulness of ex post theorization of programs. We propose an approach, located within the broad family of theory-oriented methods, for developing ex post theories of interventional programs. We use this approach to develop an ex post theory of the Michigan Intensive Care Unit (ICU) project, which attracted international attention by successfully reducing rates of central venous catheter bloodstream infections (CVC-BSIs). The procedure used to develop the ex post theory was (1) identify program leaders' initial theory of change and learning from running the program; (2) enhance this with new information in the form of theoretical contributions from social scientists; (3) synthesize prior and new information to produce an updated theory. The Michigan project achieved its effects by (1) generating isomorphic pressures for ICUs to join the program and conform to its requirements; (2) creating a densely networked community with strong horizontal links that exerted normative pressures on members; (3) reframing CVC-BSIs as a social problem and addressing it through a professional movement combining "grassroots" features with a vertically integrating program structure; (4) using several interventions that functioned in different ways to shape a culture of commitment to doing better in practice; (5) harnessing data on infection rates as a disciplinary force; and (6) using "hard edges." Updating program theory in the light of experience from program implementation is essential to improving programs' generalizability and transferability, although it is not a substitute for concurrent evaluative fieldwork. Future iterations of programs based on the Michigan project, and improvement science more generally, may benefit from the updated theory present here. © 2011 Milbank Memorial Fund.

    A limited availability of microbial protein can impair productivity in ruminants. Ruminal nitrogen efficiency might be optimised by combining high-quality forage legumes such as red clover (RC), which has unfavourably high ruminal protein degradability, with tanniferous legumes like sainfoin (SF) and birdsfoot trefoil (BT). Silages from SF and from BT cultivars [Bull (BB) and Polom (BP)] were incubated singly or in combination with RC using the Rumen Simulation Technique (n = 6). The tanniferous legumes, when compared to RC, changed the total short-chain fatty acid profile by increasing propionate proportions at the expense of butyrate. Silage from SF contained the most condensed tannins (CTs) (136 g CT kg -1 dry matter) and clearly differed in various traits from the BT and RC silages. The apparent nutrient degradability (small with SF), microbial protein synthesis, and calculated content of potentially utilisable crude protein (large with SF) indicated that SF had the greatest efficiency in ruminal protein synthesis. The effects of combining SF with RC were mostly linear. The potential of sainfoin to improve protein supply, demonstrated either individually or in combination with a high-performance forage legume, indicates its potential usefulness in complementing protein-deficient ruminant diets and high-quality forages rich in rumen-degradable protein. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    Background: Neonatal pain management guidelines have been released; however, there is insufficient systematic institutional support for the adoption of evidence-based pain management in Japan. Purpose: To evaluate the impact of a collaborative quality improvement program on the implementation of pain management improvements in Japanese neonatal intensive care units (NICUs). Methods: Seven Japanese level III NICUs participated in a neonatal pain management quality improvement program based on an Institute for Healthcare Improvement collaborative model. The NICUs developed evidence-based practice points for pain management and implemented these over a 12-month period. Changes were introduced through a series of Plan-Do-Study-Act cycles, and throughout the process, pain management quality indicators were tracked as performance measures. Jonckheere's trend test and the Cochran-Armitage test for trend were used to examine the changes in quality indicator implementations over time (baseline, 3 months, 6 months, and 12 months). Findings: Baseline pain management data from the 7 sites revealed substantial opportunities for improvement of pain management, and testing changes in the NICU setting resulted in measurable improvements in pain management. During the intervention phase, all participating sites introduced new pain assessment tools, and all sites developed electronic medical record forms to capture pain score, interventions, and infant responses to interventions. Implications for Practice: The use of collaborative quality improvement techniques played a key role in improving pain management in the NICUs. Implications for Research: Collaborative improvement programs provide an attractive strategy for solving evidence-practice gaps in the NICU setting. PMID:28114148

    Purpose We describe results from a quality improvement project undertaken to address perinatal mental healthcare for women veterans. Description This quality improvement project was conducted in a single VA healthcare system between 2012 and 2015 and included screening for depressive symptoms with the Edinburgh Postnatal Depression Scale (EPDS) three times during the perinatal period, a dedicated maternity care coordinator (MCC), an on-site clinical social worker, and an on-site obstetrician/gynecologist (Ob/gyn). Information on prior mental health diagnosis was collected by the MCC or Ob/gyn. The prevalence of perinatal depressive symptoms and receipt of mental healthcare among those with such symptoms are reported by presence of a pre-pregnancy mental health diagnosis. Assessment Of the 199 women who used VA maternity benefits between 2012 and 2015, 56% (n = 111) had at least one pre-pregnancy mental health diagnosis. Compared to those without a pre-pregnancy mental health diagnosis, those with such a diagnosis were more likely to be screened for perinatal depressive symptoms at least once (61.5% vs. 46.8%, p = 0.04). Prevalence of depressive symptoms was 46.7% among those with a pre-pregnancy mental health diagnosis and 19.2% among those without. Among those with a pre-pregnancy mental health diagnosis and depressive symptoms (n = 35), 88% received outpatient mental healthcare and 77% met with the clinical social worker. Among those without a pre-pregnancy mental health diagnosis and depressive symptoms (n = 8), none received outpatient mental healthcare, but 77.8% met with the clinical social worker. Conclusion Improving perinatal mental healthcare for women veterans requires a multidisciplinary approach, including on-site integrated mental healthcare.

    The purpose of this study was to assess the impact of an automated program on improvement in lung nodule matching efficiency. Four thoracic radiologists independently reviewed two serial chest CT examinations from each of 57 patients. Each radiologist performed timed manual lung nodule matching. After 6 weeks, all radiologists independently repeated the timed matching portion using an automated nodule matching program. The time required for manual and automated matching was compared. The impact of nodule size and number on matching efficiency was determined. An average of 325 (range, 244-413) noncalcified solid pulmonary nodules was identified. Nodule matching was significantly faster with the automated program irrespective of the interpreting radiologist (p 0.5). The automated program achieved 90%, 90%, 79%, and 92% accuracy for the four readers. The improvement in efficiency for a given patient using the automated technique was proportional to the number of matched nodules (p < 0.0001) and inversely proportional to nodule size (p < 0.05). Use of the automated lung nodule matching program significantly improves diagnostic efficiency. The time saved is proportionate to the number of nodules identified and inversely proportional to nodule size. Adoption of such a program should expedite CT examination interpretation and improve report turnaround time.

    Standardized continuous quality improvement (CQI) programs combine Web-based technologies and standardized improvement processes, tools, and expectations to enable quality-related events (QREs) occurring in individual pharmacies to be shared with pharmacies in other jurisdictions. Because standardized CQI programs are still new to community pharmacy, little is known about how they impact medication safety. This research identifies key aspects of medication safety that change as a result of implementing a standardized CQI program. Fifty-three community pharmacies in Nova Scotia, Canada, adopted the SafetyNET-Rx standardized CQI program in April 2010. The Institute for Safe Medication Practices (ISMP) Canada's Medication Safety Self-Assessment (MSSA) survey was administered to these pharmacies before and 1 year into their use of the SafetyNET-Rx program. The nonparametric Wilcoxon signed-rank test was used to explore where changes in patient safety occurred as a result of SafetyNETRx use. Significant improvements occurred with quality processes and risk management, staff competence, and education, and communication of drug orders and other information. Patient education, environmental factors, and the use of devices did not show statistically significant changes. As CQI programs are designed to share learning from QREs, it is reassuring to see that the largest improvements are related to quality processes, risk management, staff competence, and education.

    The objective of this study was to develop and evaluate the effectiveness of a school-based sleep education program aimed at improving the sleep and academic performance of school-age children. Using a community-based participatory research approach, we created a school-based sleep education program, "Sleep for Success"™ (SFS), composed of four distinct modules that addressed the children, their family and community, the school staff, and decision makers within the school setting. Implementation was carried out in three elementary schools. Seventy-one students participated in the evaluation of the program. The effectiveness of the SFS program was evaluated using non-randomized controlled before-and-after study groups (intervention and control) assessed over two time points (pre- and post-program implementation). Before (baseline) and after implementation, sleep and academic performance were measured using actigraphy and report card marks, respectively. In the intervention group, true sleep was extended by 18.2 min per night, sleep efficiency improved by 2.3%, and sleep latency was shortened by 2.3 min, and report card grades in mathematics and English improved significantly. No changes were noted in the control group. Participation in the sleep education program was associated with significant improvements in children's sleep and academic performance.

    Full Text Available Legumes play an important role as food and forage crops in international agriculture especially in developing countries. Legumes have a unique biological process called nitrogen fixation (NF by which they convert atmospheric nitrogen to ammonia. Although legume genomes have undergone polyploidization, duplication and divergence, NF-related genes, because of their essential functional role for legumes, might have remained conserved. To understand the relationship of divergence and evolutionary processes in legumes, this study analyzes orthologs and paralogs for selected 20 NF-related genes by using comparative genomic approaches in six legumes i.e. Medicago truncatula (Mt, Cicer arietinum, Lotus japonicus, Cajanus cajan (Cc, Phaseolus vulgaris (Pv and Glycine max (Gm. Subsequently, sequence distances, numbers of synonymous substitutions per synonymous site (Ks and nonsynonymous substitutions per nonsynonymous site (Ka between orthologs and paralogs were calculated and compared across legumes. These analyses suggest the closest relationship between Gm and Cc and the farthest distance between Mt and Pv in 6 legumes. Ks proportional plots clearly showed ancient genome duplication in all legumes, whole genome duplication event in Gm and also speciation pattern in different legumes. This study also reported some interesting observations e.g. no peak at Ks 0.4 in Gm-Gm, location of two independent genes next to each other in Mt and low Ks values for outparalogs for three genes as compared to other 12 genes. In summary, this study underlines the importance of NF-related genes and provides important insights in genome organization and evolutionary aspects of six legume species analyzed.

    This article is the third article in the Human Resources for Health journal's feature on the theme of leadership and management in public health. The series of six articles has been contributed by Management Sciences for Health (MSH) and will be published article-by-article over the next few weeks. The third article presents a successful application in Mozambique of a leadership development program created by Management Sciences for Health (MSH). Through this program, managers from 40 countries have learned to work in teams to identify their priority challenges and act to implement effective responses. From 2003 to 2004, 11 health units in Nampula Province, participated in a leadership and management development program called the Challenges Program. This was following an assessment which found that the quality of health services was poor, and senior officials determined that the underlying cause was the lack of human resource capacity in leadership and management in a rapidly decentralizing health care system. The program was funded by the US Agency for International Development (USAID) and implemented in partnership between the Mozambican Ministry of Health (MOH) Provincial Directorate in Nampula and Management Sciences for Health (MSH). The Challenges Program used simple management and leadership tools to assist the health units and their communities to address health service challenges. An evaluation of the program in 2005 showed that 10 of 11 health centers improved health services over the year of the program. The Challenges Program used several strategies that contributed to successful outcomes. It integrated leadership strengthening into the day-to-day challenges that staff were facing in the health units. The second success factor in the Challenges Program was the creation of participatory teams. After the program, people no longer waited passively to be trained but instead proactively requested training in needed areas. MOH workers in Nampula reported

Métodos: Estudo transversal e analítico, com 73 gestantes adolescentes de 10 a 19 anos, atendidas no Núcleo de Assistência ao Adolescente (NASA do Hospital Materno Infantil, em São Luís, Maranhão. Utilizou-se o Questionário de Frequência de Consumo Alimentar (QFCA, medidas antropométricas (peso, altura, índice de massa corporal - IMC - pré-gravídico e gravídico e questionário socioeconômico. As variáveis dependentes foram o consumo de frutas, verduras e legumes, e as independentes foram escolaridade, estado civil, raça, renda, situação demográfica, dados gestacionais e antropométricos. Resultados: Observou-se que 39,7% apresentaram IMC pré-gestacional de desnutrição, 50,7% de eutrofia, e menos de 10% sobrepeso ou obesidade. Para o IMC gestacional, os valores se alteraram, com 27,4% das gestantes desnutridas, 57,5% eutróficas e 15,1% com sobrepeso. Observou-se que os maiores percentuais de adequação para o consumo de frutas, verduras e legumes foram em adolescentes casadas ou em união estável (65,4%, que não trabalhavam (92,3% e com renda familiar menor que 1 salário mínimo (84,62%. Entretanto, a única associação positiva encontrada com o consumo de frutas, verduras e legumes foi o início do pré-natal. Conclusão: A maior parte das gestantes avaliadas apresentou-se eutrófica, apesar de cerca de um quarto apresentar baixo peso durante a gestação. Além disso, elas não consumiam uma dieta balanceada, com uma ingestão abaixo do recomendado de FVL. Entre os fatores relacionados a um melhor consumo de FVL destaca-se o início do acompanhamento pré-natal no primeiro trimestre.

    Current assessments on Output-Based Aid (OBA) programs have paid limited attention to the experiences and perceptions of the healthcare providers and facility managers. This study examines the knowledge, attitudes, and experiences of healthcare providers and facility managers in the Kenya reproductive health output-based approach voucher program. A total of 69 in-depth interviews with healthcare providers and facility managers in 30 voucher accredited facilities were conducted. The study hypothesized that a voucher program would be associated with improvements in reproductive health service provision. Data were transcribed and analyzed by adopting a thematic framework analysis approach. A combination of inductive and deductive analysis was conducted based on previous research and project documents. Facility managers and providers viewed the RH-OBA program as a feasible system for increasing service utilization and improving quality of care. Perceived benefits of the program included stimulation of competition between facilities and capital investment in most facilities. Awareness of family planning (FP) and gender-based violence (GBV) recovery services voucher, however, remained lower than the maternal health voucher service. Relations between the voucher management agency and accredited facilities as well as existing health systems challenges affect program functions. Public and private sector healthcare providers and facility managers perceive value in the voucher program as a healthcare financing model. They recognize that it has the potential to significantly increase demand for reproductive health services, improve quality of care and reduce inequities in the use of reproductive health services. To improve program functioning going forward, there is need to ensure the benefit package and criteria for beneficiary identification are well understood and that the public facilities are permitted greater autonomy to utilize revenue generated from the voucher program.

    Utilization of a radiology resident-specific quality improvement (QI) program and curriculum based on the Accreditation Council for Graduate Medical Education (ACGME) milestones can enable a program's assessment of the systems-based practice component and prepare residents for QI implementation post graduation. This article outlines the development process, curriculum, QI committee formation, and resident QI project requirements of one institution's designated radiology resident QI program. A method of mapping the curriculum to the ACGME milestones and assessment of resident competence by postgraduate year level is provided. Sample projects, challenges to success, and lessons learned are also described. Survey data of current trainees and alumni about the program reveal that the majority of residents and alumni responders valued the QI curriculum and felt comfortable with principles and understanding of QI. The most highly valued aspect of the program was the utilization of a resident education committee. The majority of alumni responders felt the residency quality curriculum improved understanding of QI, assisted with preparation for the American Board of Radiology examination, and prepared them for QI in their careers. In addition to the survey results, outcomes of resident project completion and resident scholarly activity in QI are evidence of the success of this program. It is hoped that this description of our experiences with a radiology resident QI program, in accordance with the ACGME milestones, may facilitate the development of successful QI programs in other diagnostic radiology residencies.

    The objectives of this study were to evaluate the effectiveness of Project CLEAR!, a novel simulation-based training program designed to instill Crew Resource Management (CRM) as the communication standard and to create a service-focused environment in the emergency department (ED) by standardizing the patient encounter. A survey-based study compared physicians' and nurses' perceptions of the quality of communication before and after the training program. Surveys were developed to measure ED staff perceptions of the quality of communication between staff members and with patients. Pretraining and posttraining survey results were compared. After the training program, survey scores improved significantly on questions that asked participants to rate the overall communication between staff members and between staff and patients. A simulation-based training program focusing on CRM and standardizing the patient encounter improves communication in the ED, both between staff members and between staff members and patients.

    The preservation of our genetic resources and production of high-quality seeds depends on their ability to remain viable and vigorous during storage. In a quantitative trait locus analysis on seed longevity in Medicago truncatula, we identified the bZIP transcription factor ABSCISIC ACID INSENSITIVE5 (ABI5). Characterization of Mt-abi5 insertion mutant seeds revealed that both the acquisition of longevity and dormancy were severely impaired. Using transcriptomes of developing Mt-abi5 seeds, we created a gene coexpression network and revealed ABI5 as a regulator of gene modules with functions related to raffinose family oligosaccharide (RFO) metabolism, late embryogenesis abundant (LEA) proteins, and photosynthesis-associated nuclear genes (PhANGs). Lower RFO contents in Mt-abi5 seeds were linked to the regulation of SEED IMBIBITION PROTEIN1 Proteomic analysis confirmed that a set of LEA polypeptides was reduced in mature Mt-abi5 seeds, whereas the absence of repression of PhANG in mature Mt-abi5 seeds was accompanied by chlorophyll and carotenoid retention. This resulted in a stress response in Mt-abi5 seeds, evident from an increase in α-tocopherol and upregulation of genes related to programmed cell death and protein folding. Characterization of abi5 mutants in a second legume species, pea (Pisum sativum), confirmed a role for ABI5 in the regulation of longevity, seed degreening, and RFO accumulation, identifying ABI5 as a prominent regulator of late seed maturation in legumes. © 2016 American Society of Plant Biologists.

    To improve the safety and quality of the care that radiologists provide, and to allow radiologists and radiology personnel to remain competitive in an increasingly complex environment, it is essential that all imaging departments establish and maintain managed, comprehensive, and effective performance improvement programs. Although the structure and focus of these programs can vary, a number of common components exist, many of which are now widely mandated by organizations that regulate the field of radiology. Basic components include patient safety, process improvement, customer service, professional staff assessment, and education, each of which requires strategies for implementing continuous programs to monitor performance, analyzing and depicting data, implementing change, and meeting regulatory requirements. All of these components are part of a comprehensive quality management system in a large academic radiology department. For smaller departments or practices, the gradual introduction of one or more of these components is useful in ensuring the safety and quality of their services. (c) RSNA, 2009.

    Full Text Available Psychotic disorders most commonly appear during the late teenage years and early adulthood. A focused and rapid clinical response by an integrated health team can help to improve the quality of life of the patient, leading to a better long-term prognosis. The Vancouver Coastal Health Early Psychosis Intervention program covers a catchment area of approximately 800,000 people in the cities of Vancouver and Richmond, Canada. The program provides a multidisciplinary approach to supporting patients under the age of 30 who have recently experienced first-break psychosis. The program addresses the needs of the treatment environment, medication and psychological therapies. A critical part of this support includes a program to specifically improve patients’ physical health. Physical health needs are addressed through a two-pronged, parallel approach. Patients receive routine metabolic health assessments during their first year in the program where standard metabolic parameters are recorded. Based on the results of clinical interviews and laboratory tests, specific actionable interventions are recommended. The second key strategy is a program that promotes healthy lifestyle goal development. Patients work closely with occupational therapists to develop goals to improve cardiometabolic health. These programs are supported by an active research environment where patients are able to engage in studies with a focus on improving their physical health. These studies include a longitudinal evaluation of the effects of integrated health coaching on maintaining cardiometabolic health in patients recently admitted to the program, as well as a clinical study which evaluates the effects of low versus higher metabolic risk antipsychotic drugs on central adiposity. An additional pharmacogenomic study is helping to identify genetic variants that may predict cardiometabolic changes following treatment with antipsychotic drugs.

Each replicate was planted with 100 legume trees and 100 non legume trees. The isotope plot, where 15 N was applied with 18 legume trees and 18 non legume trees. The planting distance was 1m x 1m. For the calculation of N 2 -fixation each legume and standard tree (Eucalypthus alba) was applied with 12.52g in the from of ammonium sulfate with 10.12% 15 N. The 15 N AS was applied in three splits 11 month earlier. Data obtained from this experiment showed that percentage of N derived from fixation (%N-dfF) of all legume trees was reasonable high. The legume trees used in this experiment were, Leucaena leucocephala, Acacia mangium, Caliandra tetragona, Flemengia congesta and Gliriciadia sepium with potential fixation from 62.31% to 90,68%.

    Legumes are an important plant functional group since they can form a tripartite symbiosis with nitrogen-fixing Rhizobium bacteria and phosphorus-acquiring arbuscular mycorrhizal fungi (AMF). However, not much is known about AMF community composition in legumes and their root nodules. In this study,

    Legumes represent the dominant family of many tropical forests with estimates of 120 billion legume trees in the Amazon basin alone. Many rainforest legume trees form symbioses with N2-fixing bacteria. In the process of atmospheric N2-fixation large amounts of nitrogen-rich litter are generated, supplying half of all nitrogen required to support secondary rainforest succession. However, it is unclear how N2-fixers affect the biogeochemical cycling of other essential nutrients by affecting the rates of mineral dissolution and rock weathering. Here we show that N2-fixing legumes in young Panamanian rainforests promote acidification and enhance silicate rock weathering by a factor of 2 compared to non-fixing trees. We report that N2-fixers also associate with enhanced dissolution of Al- and Fe-bearing secondary minerals native to tropical oxisols. In legume-rich neighbourhoods, non-fixers benefited from raised weathering rates relative to those of legume-free zones thus suggesting a positive community effect driven by N2-fixers. These changes in weathering potential were tracked by parallel functional and structural changes in the soil and rock microbiomes. Our findings support the view that N2-fixing legumes are central components of biogeochemical cycling, associated with enhanced release of Fe- and Al-bound P and primary mineral products (Mg, Mo). Rainforest legume services therefore bear important implications to short-term C cycling related to forest growth and the long-term C cycle related to marine carbonate deposition fuelled by silicate weathering.

    Accelerated second-degree programs are designed to provide entry into baccalaureate nursing program for people who have achieved bachelor's degree in another field. These programs were often designed to respond to nursing shortages at local and national levels. Programs commonly use a cohort model and move students through an intensive structure combining classroom and clinical requirement with a 2-year period. The accelerated second-degree nursing program, Accelerated Entry Level to Nursing program at our small liberal arts college, was considered to be successful. The program had excellent graduation rates and National Council Licensure Examination for Registered Nurses pass rates, indicating that the program was preparing the graduate to thrive in the practice setting. The program had been in existence for more than 7 years, with highly competitive admissions and high student satisfaction. The objective of this study was to provide a quality improvement assessment process to capture quantitative and qualitative information about the graduates. This information would be used to inform our own nursing education department and would provide metrics and information for nurse leaders regarding the rigor of these programs and the potential of graduates. Continuous quality improvement is a vital component in nursing education as well as in the clinical setting. With this in mind, a comprehensive review was undertaken by the nursing faculty during the eighth year of the highly successful accelerated nursing program in a small liberal arts college. This quality improvement project was designed to review existing metrics and to collect additional data through survey and focus groups in order to capture experiences of the program graduates. Graduates of the accelerated program from 2005 to 2011 were included in this study. Faculty who teach in the program participated in focus groups. From 2005 to 2011, there have been a total of 196 graduates in 8 cohorts; 194 surveys

    Introduction Mentorship has been noted as critical to medical students adapting to clinical training in the medical workplace. A lack of infrastructure in a mentoring program might deter relationship building between mentors and mentees. This study assessed the effect of a redesigned clinical mentoring program from the perspective of clerks. The objective was to assess the benefits of the redesigned program and identify potential improvements. Methods A redesigned clinical mentoring program was launched in a medical center according to previous theoretical and practical studies on clinical training workplaces, including the elements of mentor qualifications, positive and active enhancers for mentor–mentee relationship building, the timing of mentoring performance evaluation, and financial and professional incentives. A four-wave web survey was conducted, comprising one evaluation of the former mentoring program and three evaluations of the redesigned clinical mentoring program. Sixty-four fifth-year medical students in clerkships who responded to the first wave and to at least two of the three following waves were included in the study. A structured and validated questionnaire encompassing 15 items on mentor performance and the personal characteristics of the clerks was used. Mixed linear models were developed for repeated measurements and to adjust for personal characteristics. Results The results revealed that the redesigned mentoring program improved the mentors’ performance over time for most evaluated items regarding professional development and personal support provided to the mentees. Conclusions Our findings serve as an improved framework for the role of the institution and demonstrate how institutional policies, programs, and structures can shape a clinical mentoring program. We recommend the adoption of mentorship schemes for other cohorts of medical students and for different learning and training stages involved in becoming a physician. PMID

    External quality assessment (EQA) programs have been conducted by the Japanese Association of Medical Technologists (JAMT) since 1989. The nationwide EQA programs have provided feedback for improving clinical tests quality in individual laboratories. The participating laboratories have been expected to process the survey samples according to their usual practice for patient specimens. However, many problems relating to the EQA programs in clinical microbiology have been raised. Dishonesty in the responses, survey samples being handled in a manner that improves assessment results, surveys depending on volunteers because of time and cost limitations were some of the initial problems. In addition, the criteria used to evaluate the results were poorly understood, so that neither examiners not participants were clear as to how the evaluation worked. And finally, the nationwide EQA programs can detect only gross errors and use invalid methods for evaluating routine performances. They have been measuring only a few steps in specimens processing. To assess overall laboratory competence, other methods are needed. It is time to reform the JAMT nationwide EQA program to initiate real proficiency testing and to this end it is necessary to increase collaboration between JAMT and the regional associations of medical technologists, so that the improved testing program can be properly administered.

    The purpose of this study was to determine if a sports-specific training program could improve neuromuscular and performance indices in female high school basketball players. We combined components from a published anterior cruciate ligament injury prevention program for jump and strength training with other exercises and drills to improve speed, agility, overall strength, and aerobic conditioning. We hypothesized that this sports-specific training program would lead to significant improvements in neuromuscular and performance indices in high school female basketball players. Fifty-seven female athletes aged 14-17 years participated in the supervised 6-week program, 3 d·wk(-1) for approximately 90-120 minutes per session. The program was conducted on the basketball court and in weight room facilities in high schools. The athletes underwent a video drop-jump test, multistage fitness test, vertical jump test, and an 18-m sprint test before and upon completion of the training program. All the subjects attended at least 14 training sessions. After training, a significant increase was found in the mean estimated VO2max (p basketball players.

    total volatile fatty acid production was decreased with the CT-containing legumes. Protozoal count was increased with the mixtures containing LU and either SF or BTB compared with single LU. In conclusion, compared with the other legumes, SF and RC have similar advantages as they show limited proteolysis during ensiling. In addition, SF supplies more uCP relative to total CP. The CT-containing legumes also differed in their effect on ruminal fermentation and ammonia formation, probably because of their different CT contents. Thus, SF and its mixtures appear promising for improving the protein utilisation of ruminants.

  16. An analysis of synteny of Arachis with Lotus and Medicago sheds new light on the structure, stability and evolution of legume genomes

    Full Text Available Abstract Background Most agriculturally important legumes fall within two sub-clades of the Papilionoid legumes: the Phaseoloids and Galegoids, which diverged about 50 Mya. The Phaseoloids are mostly tropical and include crops such as common bean and soybean. The Galegoids are mostly temperate and include clover, fava bean and the model legumes Lotus and Medicago (both with substantially sequenced genomes. In contrast, peanut (Arachis hypogaea falls in the Dalbergioid clade which is more basal in its divergence within the Papilionoids. The aim of this work was to integrate the genetic map of Arachis with Lotus and Medicago and improve our understanding of the Arachis genome and legume genomes in general. To do this we placed on the Arachis map, comparative anchor markers defined using a previously described bioinformatics pipeline. Also we investigated the possible role of transposons in the patterns of synteny that were observed. Results The Arachis genetic map was substantially aligned with Lotus and Medicago with most synteny blocks presenting a single main affinity to each genome. This indicates that the last common whole genome duplication within the Papilionoid legumes predated the divergence of Arachis from the Galegoids and Phaseoloids sufficiently that the common ancestral genome was substantially diploidized. The Arachis and model legume genomes comparison made here, together with a previously published comparison of Lotus and Medicago allowed all possible Arachis-Lotus-Medicago species by species comparisons to be made and genome syntenies observed. Distinct conserved synteny blocks and non-conserved regions were present in all genome comparisons, implying that certain legume genomic regions are consistently more stable during evolution than others. We found that in Medicago and possibly also in Lotus, retrotransposons tend to be more frequent in the variable regions. Furthermore, while these variable regions generally have lower

    This annual report is in fulfillment of contractual obligations with Bonneville Power Administration (BPA), which is the funding source for the Oregon Department of Fish and Wildlife's (ODFW), Umatilla River Subbasin Fish Habitat Improvement Program (Program). The Program works cooperatively with private landowners to develop long-term restoration, under which, passive and active Habitat Improvement Projects are conducted. Historically, projects have included livestock exclusion fencing (passive restoration) to protect riparian habitats, along with the installation of instream structures (active restoration) to address erosion and improve fish habitat. In recent years, the focus of active restoration has shifted to bioengineering treatments and, more recently, to channel re-design and reconstruction aimed at improving fish habitat, by restoring stable channel function. This report provides a summary of Program activities for the 2004 calendar year (January 1 through December 31, 2004), within each of the four main project phases, including: (1) Implementation--Pre-Work, (2) Implementation--On Site Development, (3) Operation and Maintenance, and (4) Monitoring and Evaluation. This report also summarizes Program Administrative, Interagency Coordination, and Public Education activities.

    Nurses play an integral part in providing evidence-based care to patients with stroke, yet some patients receive unnecessary or even harmful care. The literature supports the use of multifaceted strategies to promote implementation of evidence-based practice; however, there is a gap in knowing which combinations of strategies are most successful. The purpose of this study was to determine if a tailored, multifaceted Stroke Competency Program would improve nurses' knowledge of and adherence to evidence-based practices in the care of patients with stroke. This program bundled implementation strategies of local opinion leaders, printed educational materials, and educational outreach. This study used a pretest/posttest program design. Nursing adherence was measured via documentation audits with knowledge measured by an author-developed assessment. Most participating nurses had approximately 10 years of nursing experience and were baccalaureate prepared; participation ranged from 32% to 58% (n = 88). Overall, an improvement in nursing adherence was noted after the program as well as significant improvements in nursing knowledge. Although the Stroke Competency Program improved nursing knowledge of and adherence to stroke guidelines, future research should seek to extend these findings to identify which bundle of strategies are most effective for implementing evidence into nursing practice using psychometrically sound outcome measures.

    Full Text Available The research is aimed to explore the efficiency of innovative technologies and increase the health-improving effect as a result of physical training in ecologically unfavorable conditions. A health-improving rehabilitation program, containing a set of modern means of physical rehabilitation and recreation in combination with physical exercises, was worked out to carry out the pedagogical experiment. The program includes the hydromassage, stretching exercises with biomechanical stimulation and exercises for developing weightlifting abilities. Apart from this, the interval hypoxic training was used in ‘artificially created’ favorable ecological conditions for detoxication. The students at Polotsk State University took part in the experiment. Among the assessment criteria applied by the author, there are generally acknowledged methods identifying the development of physical qualities, external respiration functions, body fat and other components composition. The experiment revealed that the innovative program had enhanced the health-improving effect compared to the traditional training programs, which was expressed by the statistically valid increase of the students’ speed- strength characteristics, flexibility, external respiration functions as well as the body fat decrease. Therefore, in order to increase a health-improving effect of physical training, the author recommends considering the specific ecological and hygienic conditions of a particular region to create the corresponding programs for group and individual health protection and recovery. The research findings can be used in physical education process at universities situated in the regions with unfavorable ecological conditions.

    Although physicians believe that medical errors should be disclosed to patients and their families, they often hesitate to do so. In this study, we assessed the effectiveness of an education program for medical error disclosure. In 2015, six medical interns and 79 fourth-year medical students participated in this study. The education program included practice of error disclosure using a standardized patient scenario, feedback, and short didactic sessions. Participant performance was evaluated with a previously developed rating scale that measures error disclosure performance on five specific component skills. Following education program, we surveyed participant perceptions of medical error disclosure with varying severity of error outcome and their satisfaction with the education program using a 5-point Likert scale. We also surveyed the change of attitude or confidence of participants after education program. The performance score was not significantly different between medical interns and medical students (p = 0.840). Following the education program, 65% of participants said that they had become more confident in coping with medical errors, and most participants (79.7%) were satisfied with the education program. They also indicated that they felt a greater duty to disclose medical errors and deliver an apology when the medical error outcome is more severe. An education program for disclosing medical errors was helpful in improving confidence in medical error disclosure. Extending the program to more diverse scenarios and a more diverse group of physicians is needed.

IR developed between rows of EG. FP was maintained, whilst RC was sow to respective forage systems. The experimental design was completely randomized, with three treatments and two replication, subdivided into parcels over time. Mean rate for forage yield and average stocking rate were 10.6, 11.6 and 14.4 t ha-1; 3.0, 2.8 and 3.1 animal unit ha-1 day-1, for the respective systems. Levels of crude protein and total digestible nutrients were 17.8, 18.7 and 17.5%; 66.5, 66.8 and 64.8%, for the respective forage systems. The presence of RC results in better and higher forage yield in the mixture, whilst FP results in greater control of SGS. The inclusion of forage legumes in pasture systems provides better nutritional rates.

    Databases for either sequence, annotation, or microarray experiments data are extremely beneficial to the research community, as they centrally gather information from experiments performed by different scientists. However, data from different sources develop their full capacities only when combined. The idea of a data warehouse directly adresses this problem and solves it by integrating all required data into one single database - hence there are already many data warehouses available to genetics. For the model legume Medicago truncatula, there is currently no such single data warehouse that integrates all freely available gene sequences, the corresponding gene expression data, and annotation information. Thus, we created the data warehouse TRUNCATULIX, an integrative database of Medicago truncatula sequence and expression data. The TRUNCATULIX data warehouse integrates five public databases for gene sequences, and gene annotations, as well as a database for microarray expression data covering raw data, normalized datasets, and complete expression profiling experiments. It can be accessed via an AJAX-based web interface using a standard web browser. For the first time, users can now quickly search for specific genes and gene expression data in a huge database based on high-quality annotations. The results can be exported as Excel, HTML, or as csv files for further usage. The integration of sequence, annotation, and gene expression data from several Medicago truncatula databases in TRUNCATULIX provides the legume community with access to data and data mining capability not previously available. TRUNCATULIX is freely available at http://www.cebitec.uni-bielefeld.de/truncatulix/.

  3. Signals exchanged between legumes and Rhizobium: agricultural uses and perspectives

    2001-01-01

    Legumes and rhizobia exchange at least three different, but sometimes complementary sets of signals. Amongst the variety of substances normally and continuously secreted into the rhizosphere by plants are phenolic compounds. Flavonoid components of these mixtures are especially active in inducing rhizobial nodulation genes. Many nodgenes exist. Some (e.g., nodD) serve as regulators of transcription, but most code for enzymes involved in the synthesis of a family of lipo-chito-oligosaccharides (LCOs) called Nod-factors. Nod-factors possess hormone-like properties, are key determinants in nodulation, and allow rhizobia to enter the plant. As Nod-factors also stimulate the synthesis and release of flavonoids from legume roots, the response to inoculation is amplified. Once the bacteria enter the plant, other sets of signals are exchanged between the symbionts. These include extra-cellular polysaccharides (EPSs) as well as proteins externalised via type-three secretion systems. These carbohydrates/proteins may be active in invasion of the root. At the time of writing, only flavonoids and Nodfactors have been chemically synthesised and of these only the former are available in large quantities. Field trials in North America show that seed application of flavonoids stimulates nodulation and nitrogen fixation in soybeans grown at low soil temperatures. The biological basis to these responses is discussed. (author)

  4. Widespread fitness alignment in the legume-rhizobium symbiosis.

    Friesen, Maren L

    2012-06-01

    Although 'cheaters' potentially destabilize the legume-rhizobium mutualism, we lack a comprehensive review of host-symbiont fitness correlations. Studies measuring rhizobium relative or absolute fitness and host benefit are surveyed. Mutant studies are tallied for evidence of pleiotropy; studies of natural strains are analyzed with meta-analysis. Of 80 rhizobium mutations, 19 decrease both partners' fitness, four increase both, two increase host fitness but decrease symbiont fitness and none increase symbiont fitness at the host's expense. The pooled correlation between rhizobium nodulation competitiveness and plant aboveground biomass is 0.65 across five experiments that compete natural strains against a reference, whereas, across 14 experiments that compete rhizobia against soil populations or each other, the pooled correlation is 0.24. Pooled correlations between aboveground biomass and nodule number and nodule biomass are 0.76 and 0.83. Positive correlations between legume and rhizobium fitness imply that most ineffective rhizobia are 'defective' rather than 'defectors'; this extends to natural variants, with only one significant fitness conflict. Most studies involve non-coevolved associations, indicating that fitness alignment is the default state. Rhizobium mutations that increase both host and symbiont fitness suggest that some plants maladaptively restrict symbiosis with novel strains. © 2012 The Author.

  5. Experimental evolution of a plant pathogen into a legume symbiont.

    2010-01-01

    Full Text Available Rhizobia are phylogenetically disparate alpha- and beta-proteobacteria that have achieved the environmentally essential function of fixing atmospheric nitrogen in symbiosis with legumes. Ample evidence indicates that horizontal transfer of symbiotic plasmids/islands has played a crucial role in rhizobia evolution. However, adaptive mechanisms that allow the recipient genomes to express symbiotic traits are unknown. Here, we report on the experimental evolution of a pathogenic Ralstonia solanacearum chimera carrying the symbiotic plasmid of the rhizobium Cupriavidus taiwanensis into Mimosa nodulating and infecting symbionts. Two types of adaptive mutations in the hrpG-controlled virulence pathway of R. solanacearum were identified that are crucial for the transition from pathogenicity towards mutualism. Inactivation of the hrcV structural gene of the type III secretion system allowed nodulation and early infection to take place, whereas inactivation of the master virulence regulator hrpG allowed intracellular infection of nodule cells. Our findings predict that natural selection of adaptive changes in the legume environment following horizontal transfer has been a major driving force in rhizobia evolution and diversification and show the potential of experimental evolution to decipher the mechanisms leading to symbiosis.

    Full Text Available A greenhouse study to evaluate adaptation of 4 herbaceous summer legumes to temporary waterlogging was conducted.  Species evaluated were Desmanthus virgatus and Aeschynomene americana in their vegetative stage, and Macroptilium lathyroides and M. atropurpureum in both vegetative and reproductive stages.  The experimental design was randomized blocks with 5 replications and treatments were:  T0, control; T1, saturation by capillary movement placing pots in buckets of 5 L with 10 cm of permanent water; and T2, flooding, placing pots in buckets of 10 L and a layer of water 5 cm above the soil.  The duration of the water treatments was 7 days. Waterlogging did not affect shoot or root biomass production nor nodulation in A. americana, whereas D. virgatus had its highest dry matter production in saturated soil (T1.  In M. lathyroides flooding tolerance was more evident in the reproductive than in the vegetative stage, probably due to more production of adventitious roots and formation of aerenchymatic tissue.  Macroptilium atropurpureum showed adaptation to temporary flooding.  Survival and quick recovery of these species would confirm their potential as forages for temporarily waterlogged soils.Keywords: Forage legumes, flooding, Aeschynomene americana, Desmanthus virgatus, Macroptilium lathyroides, Northeast Argentina.DOI: 10.17138/TGFT(2278-286

    Nationally, immunization coverage for the DTaP/3HPV/1MMR/3HepB/3Hib/1VZV antigen series in children ages 19-35 months are near or above the Healthy People 2020 target (80%). However, children in lower socioeconomic families experience lower coverage rates. Using a community-based participatory research (CBPR) approach, Community Health Improvement for Milwaukee Children (CHIMC) intervened to reduce disparities in childhood immunizations. The CHIMC adopted a self-assessment to examine the effectiveness of adhering to CBPR principles. Using behavior change models, CHIMC implemented education, social marketing campaign, and theory of planned behavior interventions. Community residents and organizational representatives vetted all processes, messages, and data collection tools. Adherence to the principles of CBPR was consistently positive over the 8-year period. CHIMC enrolled 565 parents/caregivers with 1,533 children into educational and planned behavior change (PBC) interventions, and enrolled another 406 surveyed for the social marketing campaign. Retention rate was high (80%) with participants being predominately Black females (90%) and the unemployed (64%); children's median age was 6.2 years. Increased knowledge about immunizations was consistently observed among parents/caregivers. Social marketing data revealed high recognition (85%) of the community-developed message ("Take Control: Protect Your Child with Immunizations"). Barriers and facilitators to immunize children revealed protective factors positively correlated with up-to-date (UTD) status (pmarketing message increased their immunization status from 45% baseline to 82% over 4 years. Using multilayered interventions, CHIMC contributed to the elimination of immunization disparities in children. A culturally tailored CBPR approach is effective to eliminate immunization disparities.

    2015-02-01

    Recent research has found that children who attended pre-kindergarten programs in childhood were more likely to be healthy as adults. One intuitive way of improving population health and longevity may therefore be to invest in pre-kindergarten programs. However, much of the research linking pre-kindergarten programs to health is very recent and has not been synthesized. In this paper, I review the mechanisms linking pre-kindergarten programs in childhood to adult longevity, and the experimental evidence backing up these linkages. I conclude with a critical exploration of whether investments in pre-kindergarten programs could also serve as investments in public health. Copyright © 2014 Elsevier Ltd. All rights reserved.

    The Strengthening Laboratory Management Toward Accreditation (SLMTA) program and subsequent Stepwise Laboratory Quality Improvement Process Toward Accreditation (SLIPTA) checklist were a response to the need for high-quality laboratories to combat the human immunodeficiency virus (HIV) epidemic and provide patients with the highest-quality care. The two tools work together to create a culture of quality in laboratories and allow the identification of gaps. The ultimate goal for any laboratory is to achieve a standard benchmark for quality and these programs have been highly successful in initially affecting the HIV epidemic but continuously improving laboratory quality across all diseases.

    With the increasing numbers of hybrid electric vehicle (HEV), management for two energy sources, engine and battery, is more and more important to achieve the minimum fuel consumption. This paper introduces several working modes of series hybrid electric vehicle (SHEV) firstly and then describes the mathematical model of main relative components in SHEV. On the foundation of this model, dynamic programming is applied to distribute energy of engine and battery on the platform of matlab and acquires less fuel consumption compared with traditional control strategy. Besides, control rule recovering energy in brake profiles is added into dynamic programming, so shorter computing time is realized by improved dynamic programming and optimization on algorithm.

    A novel drain-junction-assisted hot electron programming scheme has been proposed for Si nanocrystal memory devices. Different from the conventional channel hot electron (CHE) injection, two electron injection paths are responsible for the proposed scheme. Experimental results show that the new scheme has a nearly 1 V memory window increase and almost 300 times faster programming speed rather than the conventional CHE method. Meanwhile, improved data retention and endurance characteristics have also been achieved with the enlarged memory window, which is mainly due to less tunnel oxide degradation during the program/erase cycling. Therefore, the new scheme is shown to be more promising for Si nanocrystal memory application.

    Full Text Available The aim of the study was to evaluate non-legume cover crops for growing no-till grain legumes in organic farming systems. Evaluated cover crops should be able to suppress weed growth, reduce plant available nitrogen in the soil and produce large amounts of biomass with slow N mineralisation. Six non-legume species; spring rye (Secale cereale L., black oat (Avena sativa L., sunflower (Helianthus annuus L., white mustard (Sinapis alba L., buckwheat (Fagopyrum esculentum Moench and hemp (Cannabis sativa L. were tested. Plots with organic fertiliser (50 kg N ha−1 and without fertiliser incorporation at three locations in south-east Germany were trialled and the cover crops’ ability to produce biomass and accumulate N in plant compartments was evaluated. The N mineralisation from stem and leaf material was simulated using the STICS model. The biomass production ranged from 0.95 to 7.73 Mg ha−1, with fertiliser increasing the total biomass at locations with low-N status. Sunflower consistently displayed large biomass and N accumulation at all locations and fertiliser variations, although not always significantly more than other species. Most N was stored in sunflower leaf material, which can be easily mineralised making it less suited as cover crop before no-till sown spring grain legumes. Rye, which produced slightly less biomass, but accumulated more N in the stem biomass, would be better suited than sunflower in this type of system. The N mineralisation simulation from rye biomass indicated long N immobilisation periods potentially improving weed suppression within no-till sown legume cash crops.

    This annual report is in fulfillment of contractual obligations with Bonneville Power Administration (BPA), which is the funding source for the Oregon Department of Fish and Wildlife's (ODFW), Umatilla River Subbasin Fish Habitat Improvement Program (Program). The last Annual Program Report was submitted in 1997, and described projects undertaken in 1995. This report describes Program activities carried out in 2003, along with a summary of projects undertaken during the years 1996 through 2002. The Program works cooperatively with private landowners to develop long-term restoration agreements, under which, passive and active Habitat Improvement Projects are conducted. Historically, projects have included livestock exclusion fencing (passive restoration) to protect riparian habitats, along with the installation of instream structures (active restoration) to address erosion and improve fish habitat. In recent years, the focus of active restoration has shifted to bioengineering treatments and, more recently, to channel re-design and re-construction aimed at improving fish habitat, by restoring stable channel function. This report provides a summary table of past projects (1996-2002), along with a text description of more extensive habitat improvement projects, including: (1) Implementation of a four-phased project on the Lobato property (Birch Creek) beginning in 1996 and involving a demonstration bioengineering site and riparian improvements (fencing, planting), (2) Implementation of stable channel design/instream structure placement on the Houser property, East Birch Creek, beginning in 1998, an (3) Implementation of a joint, US Army Corps of Engineers/ODFW (cost share) project beginning in 2001 on the Brogoitti property, East Birch Creek, which involved implementation of stable channel design/construction and riparian improvement treatments.

    New discoveries of legumes in the lower Galilee at the prehistoric site of Ahihud in Israel shed light on early farming systems in the southern Levant. Radiocarbon dating of twelve legumes from pits and floors indicate that the farming of legumes was practiced in southern Levant as early as 10.240–10.200 (1σ) ago. The legumes were collected from pits and other domestic contexts dated to the Early Pre-Pottery Neolithic B. The legumes identified include Vicia faba L. (faba bean), V. ervilia (bitter vetch), V. narbonensis (narbon vetch), Lens sp. (lentil), Pisum sp. (pea), Lathyrus inconspicuus (inconspicuous pea) and L. hirosolymitanus (jerusalem vetchling). Comparison with coeval sites in the region show how the presence of peas, narbon vetches, inconspicuous peas, jerusalem vetchlings and bitter vetches together with faba bean and lentils is unique to the Pre-Pottery Neolithic, and might indicate specific patterns in farming or storing at the onset of agriculture.
