    Full Text Available Rudolf Steiner presented his Agriculture Course to a group of 111, farmers and others, at Koberwitz (Kobierzyce, Poland in 1924. Steiner spoke of an agriculture to ‘heal the earth’ and he laid the philosophical and practical underpinnings for such a differentiated agriculture. Biodynamic agriculture is now practiced internationally as a specialist form of organic agriculture. The path from proposal to experimentation, to formalization, to implementation and promulgation played out over a decade and a half following the Course and in the absence of its progenitor. Archival material pertaining to the dissemination of the early printed editions of ‘The Agriculture Course’ reveals that within six years of the Course there was a team of more than 400 individuals of the Agricultural Experimental Circle (AEC, each signed a confidentiality agreement, and located throughout continental Europe, and also in Australia, Britain, Canada, New Zealand, South Africa, and USA. Membership expanded to over 1000 AEC members (with a lower bound estimate of 1144 members who were committed to working collectively towards an evidence based, new and alternative agriculture, ‘for all farmers’, which was to be developed into a ‘suitable for publication’ form. That publication milestone was realized in 1938 with the release of Ehrenfried Pfeiffer’s ‘Bio-Dynamic Farming and Gardening’ which was published simultaneously in at least five languages: Dutch, English, French, German and Italian

    Full Text Available Modern educational activity requires the application of procedures and methodologies to help its projections to reach all kind of people. One of the aspects that may contribute to this purpose is to include virtual processes. In the second stage of the research project entitled «Application of a creativity model to update the administrative teaching in Colombian agricultural entrepreneurial systems» there was a specific objective aimed at the production of a virtual course as an appropriate complement to the results obtained in the first phase of the project. Thus, a work including the following points was developed: 1. Selection and preparation of contents (the book «Entrepreneurial creativity for agricultural education», produced in the first stage of the project was taken as a reference. 2. Organization of a method to study this book. 3. Definition of the characteristics and conditions of the students at the beginning of this teaching learning process (it wanted to reach all kind of people in two situations: creation of entrepreneurial projects or improvement of existing companies 4. Learning evaluation activities through virtual procedures were designed; additionally different internet links related with creativity were chosen. In all this process technicians associated to the teaching office of the La Salle University constantly participated incorporating New Technologies of Information and Communication (NTIC. The new course was creativity bases to concrete personal and entrepreneurial projects. Its contents have been applied in 2004 and 2005 with undergraduate and graduate students getting excellent results.

  12. A Short Course in General Relativity

    CERN Document Server

    Foster, James

    2006-01-01

    Suitable for a one-semester course in general relativity for senior undergraduates or beginning graduate students, this text clarifies the mathematical aspects of Einstein's theory of relativity without sacrificing physical understanding. The text begins with an exposition of those aspects of tensor calculus and differential geometry needed for a proper treatment of the subject. The discussion then turns to the spacetime of general relativity and to geodesic motion. A brief consideration of the field equations is followed by a discussion of physics in the vicinity of massive objects, including an elementary treatment of black holes and rotating objects. The main text concludes with introductory chapters on gravitational radiation and cosmology. This new third edition has been updated to take account of fresh observational evidence and experiments. It includes new sections on the Kerr solution (in Chapter 4) and cosmological speeds of recession (in Chapter 6). A more mathematical treatment of tensors and manif...

  14. Agriculture-related radiation dose calculations

    International Nuclear Information System (INIS)

    Estimates of radiation dose to the public must be made at each stage in the identification and qualification process leading to siting a high-level nuclear waste repository. Specifically considering the ingestion pathway, this paper examines questions of reliability and adequacy of dose calculations in relation to five stages of data availability (geologic province, region, area, location, and mass balance) and three methods of calculation (population, population/food production, and food production driven). Calculations were done using the model PABLM with data for the Permian and Palo Duro Basins and the Deaf Smith County area. Extra effort expended in gathering agricultural data at succeeding environmental characterization levels does not appear justified, since dose estimates do not differ greatly; that effort would be better spent determining usage of food types that contribute most to the total dose; and that consumption rate and the air dispersion factor are critical to assessment of radiation dose via the ingestion pathway. 17 refs., 9 figs., 32 tabs

  16. An investigation of the practice of scientific inquiry in secondary science and agriculture courses

    Science.gov (United States)

    Grady, Julie R.

    The purpose of this exploratory qualitative study was to investigate the practice of scientific inquiry in two secondary biology classes and one agriculture class from different schools in different communities. The focus was on teachers' interests and intentions for the students' participation in inquiry, the voices contributing to the inquiry, and students' opportunities to confront their conceptions of the nature of science (NOS). The Partnership for Research and Education in Plants (PREP) served as the context by providing students with opportunities to design and conduct original experiments to help elucidate the function(s) of a disabled gene in Arabidopsis thaliana . Transcripts of teacher and student semi-structured interviews, field notes of classroom observations and classroom conversations, and documents (e.g., student work, teacher handouts, school websites, PREP materials) were analyzed for evidence of the practice of scientific inquiry. Teachers were interested in implementing inquiry because of potential student learning about scientific research and because PREP supports course content and is connected to a larger scientific project outside of the school. Teachers' intentions regarding the implementation of inquiry reflected the complexity of their courses and the students' previous experiences. All inquiries were student-directed. The biology students' participation more closely mirrored the practice of scientists, while the agriculture students were more involved with the procedural display of scientific inquiry. All experiences could have been enhanced from additional knowledge-centered activities regarding scientific reasoning. No activities brought explicit attention to NOS. Biology activities tended to implicitly support NOS while the agriculture class activities tended to implicitly contradict NOS. Scientists' interactions contributed to implied support of the NOS. There were missed opportunities for explicit attention to NOS in all classes

  20. Agriculture

    International Nuclear Information System (INIS)

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

  1. A college course on relativity and cosmology

    CERN Document Server

    Cheng, Ta-Pei

    2015-01-01

    This advanced undergraduate text introduces Einstein's general theory of relativity. The topics covered include geometric formulation of special relativity, the principle of equivalence, Einstein's field equation and its spherical-symmetric solution, as well as cosmology. An emphasis is placed on physical examples and simple applications without the full tensor apparatus. It begins by examining the physics of the equivalence principle and looks at how it inspired Einstein's idea of curved spacetime as the gravitational field. At a more mathematically accessible level, it provides a metric description of a warped space, allowing the reader to study many interesting phenomena such as gravitational time dilation, GPS operation, light deflection, precession of Mercury's perihelion, and black holes. Numerous modern topics in cosmology are discussed from primordial inflation and cosmic microwave background to the dark energy that propels an accelerating universe. Building on Cheng's previous book, 'Relativity, Grav...

  2. An elementary course on general relativity

    International Nuclear Information System (INIS)

    This report gives an informal account of the theory of general relativity, for non-specialists. It does not contain any detailed technical expose of tensor calculus but relies instead on a number of intuitive arguments. After a brief historical introduction the notion of curvature is developed, first in two dimensions (as done originally by Gauss) and then in higher dimensions, following the ideas of Riemann. This curvature is then related to quantities of physical interest through the following steps: i) The equality of gravitational and inertial masses is discussed and presented as the ''weak equivalence principle''. ii) This is then extended to the ''strong equivalence principle'' according to the original programme of Einstein. iii) The ''strong equivalence principle'' implies the existence of a local inertial observer in any point of space-time. In a sufficiently small region of space-time this observer will not sense any gravitational field. iv) In a larger region the observer will, however, sense residual tidal forces. These forces are identified with the curvature of spacetime, to achieve a direct geometrical interpretation of gravity. v) Finally certain curvature components are related to the distribution of matter through Einstein's field equations. Section 4 contains a discussion of the classical tests of the theory and of the possibility of detecting gravitational waves. Sections 5 and 6 deal with cosmology and with the possible extension of the theory along the lines of the original ideas of Einstein, with emphasis on the dimensional reduction techniques of current interest.

    2012-04-01

    Courses of the first year at Engineering are typically basic to understanding other subjects and in many cases less attractive for students. In order to innovate and incorporate some aims of the Bologna process, here we present the development of the course of Geology and Climatology given the first year of Agricultural and Forestry degrees at the University of Córdoba. Temporal distribution of activities was as follows: a) to the whole group: 35% of master class, 5% of conferences and 10% of field trip, b) to the medium group (performance of a professional work: characterization of the geology and climatology of an area that will need to know for the courses in the coming years (for example soil science, crop sciences and environmental sciences). Students have to a) complete a literature review of all work done to date, b) use and study the geological map (1:50000) published by the Geological Survey of Spain (IGME), visit the study area in which they had to pick up rocks and subsequently to characterize them, and c) obtain meteorological data from the Spanish Agency of Meteorology (AEMET) (minimum 30 years of precipitation, 15 years of temperatures and 10 years of other variables) for a complete characterization of the climate. The assessment system for students included: attend classes, participation in practicals and excursions, carry out exercices, oral presentation of the report and a final written test. Key factors that favored student participation and interest in the course were: a) the small number of students in classes dedicated to the practicals and seminars and the continuous advice from teachers, and b) the personal choice by the student of the work area, usually close to their origin and in many cases from family property. All of this has served to students, who are involved with more dedication to the course, to solve specific problems and close to critical thinking, have contact with the real problems (in accessing the necessary data

    Too often, students in introductory courses are left with the impression that Einstein's special theory of relativity comes into play only when the relative speed of two objects is an appreciable fraction of the speed of light ("c"). In fact, relativistic length contraction, along with Coulomb's law, accounts quantitatively for the force on a…

    Zeilik, Michael; Markus, M. Jennifer

    2005-04-01

    We have designed, implemented, assessed, and revised a new conceptual physics course at the University of New Mexico. Using the NRC/NAS report ``Connecting Quarks with the Cosmos'' (2003) as a guide, we pared down the 11 questions to six based on a student poll. The instructor (MZ) reconceptualized these six into a one- semester course focused on general relativity and cosmology, while taking into account known misconceptions research. The full implementation of an active- learning version took place in Spring 2003. The classes contained about 2/3 males and 1/3 females, about 60% ``freshmen.'' Some 50% took the course to meet a requirement. Students entered with a wide variety of math backgrounds, with the men reporting more advanced courses. We report on assessments to probe the success of the course based on our learning outcomes. In math and science aptitude, females and males ranked themselves the same at the start of the course; men felt more confident at the end. Using a conceptual diagnostic test as a pre- and post assessment, we found that males outscored the females pre- and post, but the normalized gains were the same. The normalized gains on Force Concept Inventory items was 0.2; for general relativity and cosmology ones, 0.5.

  9. The Relationship between Low-carbon Agriculture and Agricultural Science and Technology Based on Gray Relational Theory

    Institute of Scientific and Technical Information of China (English)

    TAO Ai-xiang

    2012-01-01

    The agricultural energy consumption per unit of GDP is selected as an indicator for measuring the development level of low-carbon agriculture. Using gray relational theory, I analyze the relationship between development level of agricultural science and technology and development level of low-carbon agriculture in China. The results show that the correlation between the two is prominent; the number of agricultural science and technology talents, the number of agricultural science and technology patents, and the number of agricultural science and technology input are three major factors influencing the development of low-carbon agriculture. On this basis, I propose to take further effective measures, and put forth corresponding recommendations, in order to improve the level of agricultural science and technology.

  11. Capturing Weather-related Shocks In Smallholder Agriculture

    Murray, S.

    2015-12-01

    Rainfed agriculture accounts for 93% of total cultivated area in SSA (FAO, 2002) and smallholder is the predominant form of farm organization (33 million with less than 2 ha, representing 80% of all farms). At the same time, 75% of extreme poor live in rural areas and 90% rely on agriculture. A poor harvest can have significant impact on livelihood and welfare of a household with limited coping mechanisms and little savings.This study aims to shed light on how small farmers are affected by growing conditions in a given season and how well these impacts can be predicted using objective measures derived from time-series of remote-sensing data. We investigate the covariate vs idiosyncratic nature of shocks experienced at the household level, using both community-level and household-level observations. We also test the relative efficiency of different metrics in predicting shocks, acknowledging that both spatial resolution and temporal frequency are likely to be limiting factors in the objective measures. To support this analysis we draw on surveys from the Living Standards Measurement Study Integrated Surveys on Agriculture (LSMS-ISA) project. The LSMS-ISA surveys are georeferenced, multi-topic panel surveys with a strong focus on agriculture, conducted in 7 African countries. We combine the LSMS-ISA data on production and agricultural shocks with objective measures (rainfall deficit/surplus, phenological variables, water requirements satisfaction index) derived from various data sources (CHIRPS, MODIS Land Cover Dynamics, NDVI3g). Objective measures will be considered in both absolute terms as well as deviation from mean in the survey season.

  13. Food and agriculture in relation to energy, environment and resources

    International Nuclear Information System (INIS)

    Current trends in cultivated land, world population, agricultural practices food and energy are briefly reviewed. The rise in energy input/food energy output ratios with modernization is indicated. Nutritional needs, and trends in food and energy demand per capita are also indicated. Some emerging constraints in relation to soil fertility and agrochemical usage are identified. A growing pressure on land for ''energy and chemical farming'' is foreseen. Losses of native and added soil nitrogen, comparable with total industrial fertilizer nitrogen fixation, seem unavoidable for two decades at least. This consideration of trends and their interactions suggests the need for more effective interdisciplinary study, longer-term planning and international cooperation. (author)

    2009-04-01

    aggressive floods in 1500-1800 era, and actual added trends of "climate change" are towards higher temperatures, less water and higher perturbations. These long term risks are rather poorly predictable and will be handled mostly by improvements in agriculture and also by social and economic adaptations, but at shorter delays and specific areas active policies are possible and exist. An agribusiness can set his production plans lowering his global risk. Sometimes it might use prudently some financial instruments, such as "orange juice futures". When using decision making models, some utility functions may consider that severe losses have higher effects than good profits, letting ranges for business margins for insurers to be limited by concurrence at correct levels. Correct availability of credits is necessary for bad periods, and also state policies for rare bad situations, concerning agribusiness survival and also alimentary safety. Insurance products are effective aids for a growing variety of well definite natural risks, such as in cases of hailstorm, that have probabilities of occurrence measurable from previous events data, and a variety of adequate professional models are continuously made for them. Related to Universidad Politecnica de Madrid the CEIGRAM institute has started recently and is involved in agricultural insurance, being connected with insurers through ENESA and AGROMUTUA. That world is active, important, evolving, and is regulated by diverse laws.

In order to qualitatively establish the efficiency of tutoring ICTRC, this study investigates the effect of ICT resources on students’ perception and performance in ICTRC. Two hundred and forty-eight (248 students in the Department of Computer Science/ICT from two universities: a Federal and a Private University from the South-South region of Nigeria were used. A pre-test, post-test control group and quasi experimental design were utilized. Findings revealed that teaching ICTRC without using ICT resources are not effective at empowering the students with the right perception and the students are not enabled to perform to the best of their ability. Some recommendations are proffered encouraging ICT aided teaching strategies in Nigeria.

  19. Factors related to student performance in statistics courses in Lebanon

    Science.gov (United States)

    Naccache, Hiba Salim

    The purpose of the present study was to identify factors that may contribute to business students in Lebanese universities having difficulty in introductory and advanced statistics courses. Two statistics courses are required for business majors at Lebanese universities. Students are not obliged to be enrolled in any math courses prior to taking statistics courses. Drawing on recent educational research, this dissertation attempted to identify the relationship between (1) students’ scores on Lebanese university math admissions tests; (2) students’ scores on a test of very basic mathematical concepts; (3) students’ scores on the survey of attitude toward statistics (SATS); (4) course performance as measured by students’ final scores in the course; and (5) their scores on the final exam. Data were collected from 561 students enrolled in multiple sections of two courses: 307 students in the introductory statistics course and 260 in the advanced statistics course in seven campuses across Lebanon over one semester. The multiple regressions results revealed four significant relationships at the introductory level: between students’ scores on the math quiz with their (1) final exam scores; (2) their final averages; (3) the Cognitive subscale of the SATS with their final exam scores; and (4) their final averages. These four significant relationships were also found at the advanced level. In addition, two more significant relationships were found between students’ final average and the two subscales of Effort (5) and Affect (6). No relationship was found between students’ scores on the admission math tests and both their final exam scores and their final averages in both the introductory and advanced level courses. On the other hand, there was no relationship between students’ scores on Lebanese admissions tests and their final achievement. Although these results were consistent across course formats and instructors, they may encourage Lebanese universities

  1. BOOK REVIEW: A First Course in General Relativity (Second Edition) A First Course in General Relativity (Second Edition)

    Science.gov (United States)

    Poisson, Eric

    2010-05-01

    A few years ago, in my review of Sean Carroll's book in Classical and Quantum Gravity [1], I wrote that while the 1970s was the decade of Weinberg [2] and Misner, Thorne and Wheeler [3], and while the eighties was the decade of Schutz [4] and Wald [5], the 2000s was clearly the decade of Hartle [6] and Carroll [7]. In my opinion, these books continue to stand out in the surprisingly dense crowd of introductory textbooks on general relativity. At the dawn of this new decade I look forward to see what fresh pedagogical insights will be produced next, and who will be revealed as the winners of the 2010s. It is, of course, much too early to tell, but Schutz is back, and he will set the standard just as he did back in 1985. This is the long-awaited second edition of his `First Course', a short, accessible, and very successful introduction to general relativity. The changes from the first edition are modest: Schutz wisely refrained from bloating the text with new topics, and limited himself to updating his discussion of gravitational-wave sources and detectors, neutron-star and black-hole astrophysics, and suggestions for further reading. Most importantly, he completely rewrote the chapter on cosmology, a topic that has evolved enormously since the first edition. The book begins in chapter 1 with a beautiful review of special relativity that emphasizes spacetime geometry and stays away from an algebraic approach based on the Lorentz transformation, which appears only later in the chapter. This is followed up in chapters 2 and 3 with an introduction to vector and tensor analysis in flat spacetime. The point of view is modern (tensors are defined as linear mapping of vectors and one-forms into real numbers) but the presentation is very accessible and avoids an overload of mathematical fine print. In chapter 4 the book introduces the spacetime description of fluids; it is here that the energy-momentum tensor makes its first appearance. The move to curved spacetime is

  2. How do student evaluations of courses and of instructors relate?

    DEFF Research Database (Denmark)

    Sliusarenko, Tamara; Clemmensen, Line Katrine Harder; Ersbøll, Bjarne Kjær

    Course evaluations are widely used by educational institutions to assess the quality of teaching. At the course evaluations, students are usually asked to rate different aspects of the course and of the teaching. We propose to apply canonical correlation analysis (CCA) in order to investigate the...... degree of association between how students evaluate the course and how students evaluate the teacher. Additionally it is possible to reveal the structure of this association. Student evaluations data is characterized by high correlations between the variables within each set of variables, therefore two...... modifications of the CCA method; regularized CCA and sparse CCA, together with classical CCA were applied to find the most interpretable model. Both methods give results with increased interpretability over traditional CCA on the present student evaluation data. The method shows robustness when evaluations over...

    2009-01-01

    Full Text Available This paper reports a simple laboratory project to introduce students to the nonpoint source pollution, which may be an issue of great interest to both undergraduate and graduate students of environmental or agricultural chemistry courses. The aim of this work is introduce to the students the concepts and techniques such as the polymericbased controlled release system of an agrochemical, theory of diffusion (first Fick law and spectrophotometric analysis. Thus, this laboratory project includes three experimental modules to be conducted during three weeks. Programmatic contents are described in this proceeding. Students must be aware that dissemination of nutrients and pesticides is prone to occur by both surface runoff and groundwater leaching, causing damages on all neighboring land. To demonstrate dissemination of such pollutants, we have chosen inorganic phosphorus as example of a common agrochemical. Students are invited to follow the eventual movement of the inorganic P into the groundwater. With this purpose, gelatin gels containing inorganic P were prepared to obtain a continuous release of inorganic P at a controlled rate. The slow release of P allows fewer applications and less active ingredient needed, helping to prevent leaching, with consequent reduction of groundwater contamination. At this point, students are able to compare the advantages of slow release inorganic P vs. its application by conventional methods.Este trabalho descreve uma experiência laboratorial simples para introduzir o conceito de poluição disseminada (nonpoint source pollution a estudantes do Ensino Secundário e Universitário das áreas de Ambiente e de Agricultura.

    Full Text Available   In-Service training is among the important tools for updating the professional capabilities of librarians and skilled manpower working in research and educational institutions. Agriculture Scientific Information and Documentation Center (ASDIC, during the 2000-2004 periods, offered forty in-service courses. The present paper investigates the views of the instructors and learners participating in these courses. Findings indicate that 79% of instructors were satisfied with courses scheduling while 36% were dissatisfied with lighting, acoustics and air conditionings in the classes. 80% of the learners were satisfied with Courses notifications while 38% were dissatisfied with extracurricular activities. However there was a 85% satisfaction rate regarding the command and preparedness of instructors. The instructors proposed more specialized courses with shorter schedules, higher coordination with specialist groups within ASIDC in design and implementation of courses, as well as coordination with instructors for course scheduling. Learners proposed course follow-ups as well as instruction courses being offered in provinces that are equipped for it.

    Full Text Available Agriculture and entrepreneurship are tools of salvaging poverty, especially among agriculturally educated youths. This study therefore investigated descriptive norms, perceived economic viability and behavioural intention regarding animal-agriculture based entrepreneurship among final year agriculture related students in Ibadan, Nigeria. Four hundred and twenty one copies of randomly administered questionnaires yielded data whose analysis reveal that a little above half of the respondents have ‘serious’ behavioural intention to engage animal-agriculture based entrepreneurship. Marital status, institutional category and discipline affiliation had significant effects on this behavioural intention (p0.05. Age and descriptive norms are significantly related to this behavioural intention, but perceived economic viability is the best predictor of same (p<0.01. Being married, a college rather than a university student as well as being in animal-related discipline are associated with greater behavioural intention to engage in animal-agriculture based entrepreneurship.

  1. Runoff-related agricultural impact in relation to macroinvertebrate communities of the Lourens River, South Africa.

    Thiere, Geraldine; Schulz, Ralf

    2004-07-01

    A field study at the Lourens River, South Africa, was undertaken during the pesticide application period between November 2001 and January 2002 in order to investigate the potential relation of agricultural pollution to the aquatic macroinvertebrate fauna. The upper regions of the Lourens River were free of contamination (LR1), whereas subsequent stretches flowing through a 400-ha orchard area (LR2) received transient insecticide peaks. Continuously operating suspended-particle samplers as well as flood samplers operating during runoff events were used to measure pesticide contamination. In addition, various physicochemical and morphological parameters were examined. A survey of the macroinvertebrate communities associated with the rocky substrates was carried out every three weeks. Community indices were calculated using the South African Scoring System (SASS 5) for bioassessment of water quality in rivers. The two sites differed in pesticide pollution as well as in average turbidity levels (LR1 5.5 mg/L; LR2 64.3 mg/L), but were similar in bottom substrate composition and most other abiotic factors. At the downstream site (LR2), pesticide values of 0.05 microg/L azinphos-methyl in water as well as 49 microg/kg azinphos-methyl, 94 microg/kg chlorpyrifos and 122 microg/kg total endosulfan in suspended particles were found during runoff conditions. The macroinvertebrate communities of the two sampling sites were similar in terms of number of total individuals, but differed significantly (ANOVA) in average number of taxa (LR1 11.7, LR2 8.9). Seven out of 17 investigated taxa occurred in significantly reduced numbers or were even absent at the downstream site LR2. The community characteristics determined by SASS 5 showed a significantly less sensitive community structure at the downstream site (TS 41; ASPT 4.6), indicating continuously lower water quality compared to site LR1 (TS 80; ASPT 6.9). It is concluded that the Lourens River macroinvertebrate communities are

  10. Rearward Visibility Issues Related to Agricultural Tractors and Self-Propelled Machinery: Contributing Factors, Potential Solutions.

    Science.gov (United States)

    Ehlers, S G; Field, W E

    2016-01-01

    As the size, complexity, and speed of agricultural tractors and self-propelled machinery have increased, so have the visibility-related issues, placing significant importance on the visual skills, alertness, and reactive abilities of the operator. Rearward movement of large agricultural equipment has been identified in the literature as causing both fatalities and injuries to bystanders who were not visible to the operator and damage to both the machine and stationary objects. The addition of monitoring assistance, while not a new concept, has advanced significantly, offering agricultural machinery operators greater options for increasing their awareness of the area surrounding the machine. In this research, we attempt to (1) identify and describe the key contributors to agricultural machinery visibility issues, i.e., operator-related and machine-related factors, and (2) enumerate and evaluate the potential solutions being offered that address these factors. Enhanced operator safety and efficiency should result from a better understanding of the efforts to solve the visibility problems inherent in large tractors and self-propelled agricultural machinery.

    The objective of this study was to relate earthworm assemblage structure with three different soil use intensities, and to indentify the physical, chemical, and microbiological soil variables that are associated to the observed differences. Three soil uses were evaluated: 1-Fifty year old naturalized grasslands, low use intensity; 2-Recent agricultural fields, intermediate use intensity, and 3-Fifty year old intensive agricultural fields, high use intensity. Three different sites for each soil use were evaluated from winter 2008 through summer 2011. Nine earthworm species were identified across all sampling sites. The sites shared five species: the native Microscolex dubius, and the introduced Aporrectodea caliginosa, A. rosea, Octalasion cyaneum, and O. lacteum, but they differed in relative abundance by soil use. The results show that the earthworm community structure is linked to and modulated by soil properties. Both species abundance and diversity showed significant differences depending on soil use intensity. A principal component analysis showed that species composition is closely related to the environmental variability. The ratio of native to exotic species was significantly lower in the intensive agricultural system when compared to the other two, lower disturbance systems. Microscolex dubius abundance was related to naturalized grasslands along with soil Ca, pH, mechanical resistance, and microbial respiration. Aporrectodea caliginosa abundance was related to high K levels, low enzymatic activity, slightly low pH, low Ca, and appeared related to the highly disturbed environment. Eukerria stagnalis and Aporrectodea rosea, commonly found in the recent agricultural system, were related to high soil moisture condition, low pH, low Ca and low enzymatic activity. These results show that earthworm assemblages can be good indicators of soil use intensities. In particular, Microscolex dubius, Aporrectodea caliginosa, and Aporrectodea rosea, showed different

Three different sites for each soil use were evaluated from winter 2008 through summer 2011. Nine earthworm species were identified across all sampling sites. The sites shared five species: the native Microscolex dubius, and the introduced Aporrectodea caliginosa, A. rosea, Octalasion cyaneum, and O. lacteum, but they differed in relative abundance by soil use. The results show that the earthworm community structure is linked to and modulated by soil properties. Both species abundance and diversity showed significant differences depending on soil use intensity. A principal component analysis showed that species composition is closely related to the environmental variability. The ratio of native to exotic species was significantly lower in the intensive agricultural system when compared to the other two, lower disturbance systems. Microscolex dubius abundance was related to naturalized grasslands along with soil Ca, pH, mechanical resistance, and microbial respiration. Aporrectodea caliginosa abundance was related to high K levels, low enzymatic activity, slightly low pH, low Ca, and appeared related to the highly disturbed environment. Eukerria stagnalis and Aporrectodea rosea, commonly found in the recent agricultural system, were related to high soil moisture condition, low pH, low Ca and low enzymatic activity. These results show that earthworm assemblages can be good indicators of soil use intensities. In particular, Microscolex dubius, Aporrectodea caliginosa, and Aporrectodea rosea

    Emerging contaminants have received much attention in recent years due to their presence in surface waters, but little attention has been paid to their occurrence in agricultural irrigation waters. This study investigated the occurrence of these compounds in an agricultural irrigation network in northeastern Spain and, for the first time, using two plant uptake models, estimated the concentration of selected micropollutants in crops. The concentration of micropollutants in agricultural irrigation waters ranged from 10 to 5130 ng L{sup -1} and exhibited some attenuation over the course of the irrigation network. Bromoform, chloroform, diclofenac, caffeine, ibuprofen, naproxen, methyl dihydrojasmonate, galaxolide, butylated hydroxytoluene, and butylated hydroxyanisole were the most abundant contaminants (> 200 ng L{sup -1}, on average). The estimated concentration of micropollutants in crops ranged from < 1 to 7677 ng kg{sup -1}, with the neutral compounds being the most abundant. Moreover, the predicted data obtained by fate models generally agreed with experimental data. Finally, human exposure to micropollutants through fruit and vegetable consumption was estimated to be 9.8 {mu}g per person and week ({Sigma} 27 contaminants detected). Further studies are needed to determine the health implications that the presence of these compounds in fruit and vegetables may have for consumers.

    Full Text Available Many U.S. colleges and universities are concerned with how best to prepare students to become globally competent citizens. Therefore, the need existed to examine the general global competence of students enrolling in international dimension (ID courses at Oklahoma State University. This investigation was a census study; the target population included all undergraduate students (N = 147 enrolled in three ID courses offered in the College of Agricultural Sciences and Natural Resources (CASNR during the fall semester of the 2010–2011 academic year. General knowledge instruments were used to gather pretest and posttest data to measure differences. Although students’ post-course scores were higher than pre-course scores, their overall performance was below 60%. This difference in knowledge gain connoting general global competence was statistically significant (p < .05, but the corresponding effect size was small, which signaled little practical significance. Whether ID courses are an efficacious way of achieving substantial change in students’ general global competence remains an open question. A more appropriate method to assess change in general global competence may be writing assignments. Faculty are encouraged to improve their ID courses by infusing learning experiences that stand to enhance students’ general global competence while complementing content-specific objectives.

    Full Text Available Problem statement: The bottom line in agricultural trade is that manufacturers are demanding agricultural products that are produced in a sustainable way and with assurance that they are truly conforming to the standards of Good Agriculture Practice. Towards this objective, attention has been given on sustainable agricultural productions in Malaysia. This study is an attempt to investigate job performance of extension workers in terms of competency in relation to the Good Agricultural Practices. This research investigates the influence of competencies on extension workers’ job performance at the department of agriculture in Malaysia with the emphasis of having both human development competencies and technical competencies in order to perform extension job. Approach: Stratified random sampling technique employed to select 210 extension workers from the Department of Agriculture in four states of Malaysia. A structured research instrument was utilized to survey extension workers’ competency and job performance. To test the extent research data support the MLR model, Enter regression method was used. Results: Results showed that out of the nine competencies included in the regression model only four competencies contributed significantly in explaining the variation of job performance. The R2 value of 0.544 implies that the nine predictors explain about 54.4% of the variance in the extension workers' job performance. Conclusion/Recommendations: The findings suggest that the data dose not fully support the proposed nine-predictors multiple linear regression model. Finding was contrary to the expectations, since human development areas of competencies did not contribute to the job performance. Hence extension workers are not much involved in human development aspects of their job and they give primary attention to technology transfer rather than human development.

Basics of the theory of groups and Lie algebras are explained, with discussion of the group of rotations and the Lorentz and Poincaré groups. In addition, a concise account of representation theory and of tensor calculus is provided. Quantization of the electromagnetic field in the radiation range is fully discussed. The essentials of the Lagrangian and Hamiltonian formalisms are reviewed, proceeding from systems with a finite number of degrees of freedom and extending the discussion to fields. The final four chapters are devoted to development of the quant...

  7. [The role of national rural organization and agricultural extension services in relation to women].

    Science.gov (United States)

    Martius Von Harder, G

    1985-01-01

    Rural extension services are designed to provide rural dwellers with information needed to further technical or social development and to solve problems. Extension agents should be fully aware of their responsibility for the advice they provide. The number of rural and agricultural development and extension agencies has multiplied greatly in the past 2 decades. Agricultural extension is the principal component of most rural development strategies. Training given to men is usually economic, while that for women is devoted to household and social functioning. Programs for women usually lag general development programs. Training of women is usually not included in agricultural extension programs, especially in countries practicing segregation of the sexes. Agricultural extension programs are generally limited to cultivation techniques and neglect transformation and storage of crops and seed preparation for increased production. Measures that could improve productivity of women's agriculture-related work are expected to be delivered through the intermediacy of their husbands, but the husbands may not appreciate the import of such messages if they are not familiar with their wives' work. Agricultural training should consider all stages of production, should be delivered to the individuals actually performing the tasks, and should be ecologically appropriate. The overall objective of agricultural extension is to increase production, but most programs do not specify who is to use the surplus or to benefit from it. The rural population or the urban population may be the prime beneficiary, or cash crops may be produced for export. Although increased production should benefit the rural population through a better food supply, in reality most extension programs are devoted to cash crops for export and are less than fully successful because of problems of crop distribution and marketing and other shortcomings. Where men and women perform the same agricultural work, it should

  8. Walking the Pens: A Case Study of Secondary Agriculture Teachers’ Experiences Using a Serious Digital Game in an Introductory Animal Science Course

    Directory of Open Access Journals (Sweden)

    J. C. Bunch

    2015-02-01

    Full Text Available In a world where knowledge is a click away, today’s students need information delivered in ways that meet their expectations as digital natives. Serious digital games are one way to meet the demand. This particularistic case study sought to understand agriculture teachers’ experiences using a serious digital game in an introductory animal science course. Three themes emerged from the data collected: 1 the real-world context provided by the game; 2 the game’s potential to promote students’ agricultural awareness; and 3 teachers’ positioning of the game as a secondary teaching approach. Based on these findings, it can be recommended that professional development opportunities be created for teachers to learn how to use serious digital games more effectively in other situations. Inservice workshops focused on using digital games as a primary approach to teaching secondary agricultural education curricula, especially when simulations are necessary for teaching content. Because agricultural literacy was an unintended outcome, future research should focus intentionally on the impact serious digital games have on agricultural literacy.

  9. IS IT NECESSARY TO TEACH THE THEORY OF RELATIVITY IN GENERAL PHYSICS COURSE

    Directory of Open Access Journals (Sweden)

    Sergey N. Kolgatin

    2015-01-01

    Full Text Available The aim of the present investigation is to discuss and study the general structure of the course of Physics at the high school in an extended sense. In a narrower sense, the author wonders about the necessity for inclusion of the section «Theory of Relativity» in the General Physics course, and discusses the possible site of this issue in the order of presentation.Methods. A method for designing Physics course in modern conditions requires certain sophistication from a lecturer. This is due to the strong reduction of Physics course occurred in recent years, and due to a number of objective and subjective reasons. Planning the course structure, one has to make the selection of most significant questions sacrificing minor and less significant issues. This process is particularly exacerbated by severe restrictions on the time allowed for the subject. It is necessary to re-examine the content of the course due to the recent reduction in lecture hours on Physics. In this case, it would be undesirable to neglect the substantial parts of the subject content which are important conceptually or in its applications, e.g. the Relativity Theory. The author discusses two ways of disposition of the relevant material in the course structure, and correlates them with the required level of Physics teaching. In the first approach the Relativity Theory course is considered as a part of Modern Mechanics and is placed in the first semester immediately following Kinematics. In the second approach, Relativistic Physics is presented as a result of deduction, as a generalized theory explaining the unity of the world and the objective existence of physical laws; in this case, the section is better to locate after Optics, immediately before Atomic Physics.Results. As a result of consideration, the author proves the conclusion that the inclusion of the Relativistic Theory course in a number of sections of General Physics is necessary. The author offers a list of

    2012-12-01

    During the fall 2012 semester, students in two introductory courses at Susquehanna University - EENV:101 Environmental Science and POLI:131 World Affairs - will participate together in an online international relations simulation called Statecraft (www.statecraftsim.com). In this strategy game, students are divided into teams representing independent countries, and choose their government type (democracy, constitutional monarchy, communist totalitarian, or military dictatorship) and two country attributes (industrial, green, militaristic, pacifist, or scientific), which determine a set of rules by which that country must abide. Countries interact over issues such as resource distribution, war, pollution, immigration, and global climate change, and must also keep domestic political unrest to a minimum in order to succeed in the game. This simulation has typically been run in political science courses, as the goal is to allow students to experience the balancing act necessary to maintain control of global and domestic issues in a dynamic, diverse world. This semester, environmental science students will be integrated into the simulation, both as environmental advisers to each country and as independent actors representing groups such as Greenpeace, ExxonMobil, and UNEP. The goal in integrating the two courses in the simulation is for the students in each course to gain both 1) content knowledge of certain fundamental material in the other course, and 2) a more thorough, applied understanding of the integrated nature of the two subjects. Students will gain an appreciation for the multiple tradeoffs that decision-makers must face in the real world (economy, resources, pollution, health, defense, etc.). Environmental science students will link these concepts to the traditional course material through a "systems thinking" approach to sustainability. Political science students will face the challenges of global climate change and gain an understanding of the nature of

  14. Determination of radiocaesium in agriculture-related water samples containing suspended solids using gelling method

    International Nuclear Information System (INIS)

    After the TEPCO Fukushima Dai-ichi Nuclear Power Plant accident in 2011, the radiocaesium, which flowed into the paddy fields via irrigation water, have been widely investigated. When the concentration of radiocaesium in the water samples containing suspended solids were directly measured using a high purity germanium detector with a 2 L marinelli beaker, the radiocaesium concentration might be overestimated due to the sedimentation of the suspended solids during the measurement time. In fact, the values obtained by the direct method were higher than those obtained by the filtering method and/or the gelling method in most of the agriculture-related water samples. We concluded that the gelling method using sodium polyacrylate can be widely adapted for the analysis of the total radiocaesium in the agriculture-related water samples because of its many advantage such as simple preparation procedure, accurate analysis values, excellent long-term stability of geometry and low operating cost.

    Full Text Available The article analyzes the development of agriculture and trade relations in the Caucasus in the early 20th century. This article utilizes the records of Georgian national archives, pre-revolutionary periodicals and monographic literature published in pre-revolutionary, soviet and Russian contemporary periods. The authors used the research methods such as principles of objectivity, historicism, systematic, comprehensive accounting of the economic indicators of agriculture development and trade in the Caucasus and the maximum possible neutrality of the researcher to interpret factual material. The authors come to the conclusion that the development of agriculture in the Caucasus after the revolutionary upheavals of 1905-1907 years in the subsequent period before the First World War entered into the stage of recovery. The reasons of this phenomenon became the discovery of significant quantities of oil, cement, manganese and other fields. The objects of the industry demanded also the additional food supply, this enabled the agriculture in the Caucasus to develop actively.

  17. Secondary school physics availability in an urban setting: Issues related to academic achievement and course offerings

    Science.gov (United States)

    Kelly, Angela M.; Sheppard, Keith

    2009-10-01

    High school physics is a gateway course for post-secondary study in science, and an essential component in the formation of students' scientific literacy. The opportunity to study physics is not universally available for children in U.S. schools, particularly in urban areas. Restricted science opportunities result in inequitable participation and a barrier to future participation in STEM-related fields. Although the national trend in physics enrollment has recently shown an increase, the percentage of participation is much lower for students in urban schools. We examined the availability of physics in New York City, and whether access was related to academic achievement measures, such as prior science performance, and graduation and college attendance percentages. High schools that offered physics were compared to those that did not, and patterns in types of available physics courses were examined. The findings substantiate the compelling need to explore the barriers to increased physics access and participation for urban youth.

    2013-05-01

    Full Text Available Agricultural land management, such as fertilization, liming, and tillage affects soil properties, including pH, organic matter content, nitrification rates, and the microbial community. Three different study sites were used to identify microorganisms that correlate with agricultural land use and to determine which factors regulate the relative abundance of the microbial signatures of the agricultural land-use. The three sites included in this study are the Broadbalk Experiment at Rothamsted Research, UK, the Everglades Agricultural Area, Florida, USA and the Kellogg Biological Station, Michigan, USA. The effects of agricultural management on the abundance and diversity of bacteria and archaea were determined using high throughput, barcoded 16S rRNA sequencing. In addition, the relative abundance of these organisms was correlated with soil features. Two groups of microorganisms involved in nitrogen cycle were highly correlated with land use at all three sites. The ammonia oxidizing-archaea, dominated by Ca. Nitrososphaera, were positively correlated with agriculture while a ubiquitous group of soil bacteria closely related to the diazotrophic symbiont, Bradyrhizobium, was negatively correlated with agricultural management. Analysis of successional plots showed that the abundance of ammonia oxidizing-archaea declined and the abundance of bradyrhizobia increased with time away from agriculture. This observation suggests that the effect of agriculture on the relative abundance of these genera is reversible. Soil pH and NH3 concentrations were positively correlated with archaeal abundance but negatively correlated with the abundance of Bradyrhizobium. The high correlations of Ca. Nitrososphaera and Bradyrhizobium abundances with agricultural management at three long-term experiments with different edaphoclimatic conditions allowed us to suggest these two genera as signature microorganisms for agricultural land use.

    Agriculture is known to be a risk-filled industry in South Korea, as it is worldwide. The aims of this study were to identify the magnitude of farm work-related injuries and evaluate the association between injury and possible risk factors. Farmers, including farm members (N = 16,160), were surveyed. After excluding 7 subjects with missing data in questions about injury, 16,153 farmer responses were used for the analysis. Of the 16,153 farmers, 3.6% answered having at least one farm work-related injury requiring outpatient treatment or hospitalization during 2012. The proportion of injured men (4.3%) was 1.5 times higher than women (2.9%). From an age perspective, the proportion was 1.3% of those aged 49 or below, 2.7% of those aged 50-59, 4.2% of those aged 60-69, 4.2% of those aged 70-79, and 3.1% of those aged 80 or above. We used a multivariate logistic regression analysis with a stepwise model (forward) for risk factors (gender, age, farm ownership, farm type, work years in agriculture, work months during 2012, night work experience, and work experience under the influence of alcohol). The increased risk of farm work-related injuries significantly remained associated with age, farm ownership, and experience of night work. Further studies should be conducted to consistently identify injury characteristics, especially for old farmers, considering the crop cultivation in Asian countries. PMID:27428880

    In courses where topics are sensitive or even considered taboo for discussion, it can be difficult to assess students' deeper learning. In addition, incorporating a wide variety of students' values and beliefs, designing instructional strategies and including varied assessments adds to the difficulty. Journal entries or response notebooks can highlight reflection upon others' viewpoints, class readings, and additional materials. These are useful across all educational levels in deep learning and comprehension strategies assessments. Journaling meshes with transformative learning constructs, allowing for critical self-reflection essential to transformation. Qualitative analysis of journals in a death and dying class reveals three transformative themes: awareness of others, questioning, and comfort. Students' journal entries demonstrate transformative learning via communication with others through increased knowledge/exposure to others' experiences and comparing/contrasting others' personal beliefs with their own. Using transformative learning within gerontology and geriatrics education, as well as other disciplined aging-related courses is discussed. PMID:25386895

    Full Text Available This study assesses qualitative information from studies that address the problems incurred by agricultural pilots in the execution of their work, which may be related to the occupational health and safety. The aim is to investigate whether the evolution of the technologies used in agricultural aviation is accompanied by an improvement in working conditions. In order to achieve this, it was performed a systematic review through computerized search engines to gather existing information on this subject. Data synthesis included the exposure factors presented in work environment and their relations with occupational health and safety. The main problems associated with the health and safety covered in the studies includes exposure to chemicals, noise exposure and unfavorable thermal conditions, improper use or lack of personal and collective protective equipment, team management and occupational health management. Although they are not treated in more detail, other problems are presented in studies that evaluated the conditions of the work environment. These include training and education, working time management, shocks and vibrations, gravitational forces, personal relationships, weather conditions and pilot’s responsibilities.

    Full Text Available Orientation: If South African organisations are to retain talented and skilled staff, they need to consider the psychological needs of employees and their predictors.Research purpose: The aim of this study was to investigate the relationship between manager relations, the satisfaction of the psychological needs of employees and their intentions to leave.Motivation for the study: The effective retention of skilled employees is necessary in organisations in South Africa. However, studies on the psychological processes (and specifically the satisfaction of psychological needs, through which manager relations could promote the retention of staff, are necessary.Research design, approach and method: The authors used a cross-sectional survey design. They drew convenience samples of managers in agricultural organisations (N = 507 in South Africa. They administered the Manager Relations Scale, the Work-related Basic Need Satisfaction Scale and the Turnover Intention Scale. Main findings: The results confirmed a model in which manager relations affected the satisfaction of psychological needs and intentions to leave. Autonomy satisfaction mediated the relationship between manager relations and the intentions of employees to leave.Practical/managerial implications: Managers should participate in training on applying self determination theory to support the autonomy and the relatedness satisfaction of employees.Contribution/value add: This study contributes to the literature by exploring the processes through which manager relations influence the intentions of employees to leave.

    The link between family relations and well-being in old age has received ample attention in the international literature, but remains least examined in the Arab region where cultural ideals assume positive intergenerational relations within families as the norm. In this paper, we employ survey data collected in Greater Beirut in 2009 to explore associations between family relations and health. over the life course. We tested (1) the extent to which age and social relation characteristics predict health; and (2) whether the association between age and health is stronger for those who report: smaller social networks and poorer relationship quality. We employed self-rated health and self-reported chronic illness as the health outcome measures and:social network size, positive quality and negative quality with family members as the social relations measures. Our findings suggest that social relations are differentially important depending on the health status indicator examined. The single dimension that influenced both self-rated health and the probability of reporting a chronic illness was positive relationship quality with spouse. Further, social relations, particularly having a negative relationship quality with spouse and adult child, exert stronger effects on both self-rated health and chronic illness for older compared to younger adults. The findings of the present study are important for clinical practitioners who often consider the role and importance of available social resources as they address the health needs of older adults.

    Full Text Available The study examines various aspects of student teachers' initial motivation for educational psychology course and the motivation's effect on student teachers' engagement in a specific academic activity and on the final course achievement. At the beginning of the academic year 2004/2005 undergraduate student teachers filled in the Motivated Strategies for Learning Questionnaire (MSLQ, Pintrich et al., 1991, the part which assesses students' motivational orientations. During the academic year students prepared and then presented to their colleagues their seminar work in groups. After each presentation, members of the group assessed the quality of their individual preparation, analyzed the quality of group work and assessed their part of the seminar presentation. Students' achievement was measured by an exam after completing the entire educational psychology course. The results showed that those students who had found the educational psychology course interesting and useful, and who had participated in the course because of extrinsic reasons prepared seminar work better and assessed their seminar presentation with higher marks than those with low motivation for the course. Students' engagement in individual study and self-assessment of seminar presentation were related to the final course grade. In addition, students' perception of the course as interesting and useful (task value independently predicted final course grade, over and above the account of previous academic achievement.

    Mobility is the most studied and most relevant physical ability affecting quality of life with strong prognostic value for disability and survival. Natural selection has built the "engine" of mobility with great robustness, redundancy, and functional reserve. Efficient patterns of mobility can be acquired during development even by children affected by severe impairments. Analogously, age-associated impairments in mobility-related physiological systems are compensated and overt limitations of mobility only occur when the severity can no longer be compensated. Mobility loss in older persons usually results from multiple impairments in the central nervous system, muscles, joints, and energetic and sensory physiological systems. Early preclinical changes in these physiological systems that precede mobility loss have been poorly studied. Peak performance, rate of decline, compensatory behaviors, or subclinical deterioration of physiological resources may cumulatively influence both timing of mobility loss and chances of recovery, but their role as risk factors has not been adequately characterized. Understanding the natural history of these early changes and intervening on them would likely be the most effective strategy to reduce the burden of disability in the population. For example, young women with low bone peak mass could be counseled to start strength resistance exercise to reduce their high risk of developing osteoporosis and fracture later in life. Expanding this approach to other physiological domains requires collecting and interpreting data from life course epidemiological studies, establishing normative measures of mobility, physical function, and physical activity, and connecting them with life course trajectories of the mobility-relevant physiological domains.

  14. Evaluation of the Performance of Financial Support for Agriculture in Guizhou Province Using Secondary Relative Benefit Model Based on DEA

    Institute of Scientific and Technical Information of China (English)

    2012-01-01

    We use the secondary relative benefit model based on DEA to evaluate the performance of agricultural financial expenditure in Guizhou Province, which can give due consideration to the production effectiveness determined by objective natural conditions, and management effectiveness of all regions (as decision-making body) in the use of financial fund for supporting agriculture. In general, there is north-south gradient difference in the performance of financial support for agriculture between regions in Guizhou Province. The drought in 2010 has significant impact on the technical efficiency in the whole province; the performance score of each item in Liupanshui City and Southwest Guizhou is very low; the technical efficiency and management efficiency in most regions need to be improved. In order to improve the performance of financial support for agriculture, we need to ensure the scale of input; at the same time, provide appropriate preferential financial policies for agricultural infrastructure, especially the construction of rural water conservancy, development and promotion of agricultural science and technology, and other fields; adopt the way of special check and acceptance of supporting projects to strengthen the use management of the fund for agriculture.

    Full Text Available Introduction: Nowadays, the social networks are more present in people’s daily lives, especially students, becoming a reality in the educational environment. More than entertainment, these networks have been a valuable interaction tools to passing information through. Objective: In this scenario, the aim of this research is to observe the interpersonal and intragroup interaction abilities in a group of undergraduate students in a public university in order to understand the formation and expansion of social networks initiated through personal contact and extended to the virtual universe. In that sense, it aims specifically at mapping the students interpersonal interactions in the creation of social networks and the expansion of their relations. It describes which are the most used forms of interaction and it gets a basic profile data of the actors. Methodology: To better understand the reality of these subjects it has been adopted as an instrument of data collection, a questionnaire consisting of closed questions directed to students of the course mentioned. A total of 95 student names were enrolled in the course in last May, who could be marked by the respondents. The survey was carried out throughout June 2014 and tallied 71 answered questionnaires. After the data collection, the data were tabulate and it was applied the Gephi software. Results: The results show a tendency to form an extensive network within the course, but it is more intense among certain students, forming small groups and the existence of actors-bridge. The article also showed that there was a clear transposition from the personal relationship contact to the virtual environment. Conclusion: Social networks can increasingly serve as a space for communication and interaction, although the use of these networks in education is related to the teaching and learning process, making advances in the ways of interaction and access to information and search among its users

    International Nuclear Information System (INIS)

    This paper reports on the effects of increasing trace gas concentrations and concomitant climate change on agriculture which are likely to be substantial. With cropland and pasture now covering 2, CH4, and N2O. Land clearing for agriculture and other purposes is responsible for 10 to 30% of total net CO2 emissions; the rest is due to fossil fuel combustion. In addition, intentional burning of agricultural wastes, grasslands, and forests makes a significant contribution to global emissions of CO, CH4, NOx and N2O. Methane emissions from anaerobic respiration in rice (Oryza sativa L.) paddies and domestic animal remains account for 30 to 50% of the global total, making agriculture the dominant anthropogenic source of this gas. The amount of N2O emitted as a result of N fertilizer applications is highly uncertain, but may be on the order of 10% of total N2O emissions. Future agricultural greenhouse gas emissions will be affected by population growth, economic development, and agricultural practices. Greenhouse gas emissions are likely to increase substantially in the future unless steps are taken to control them. Investigating potential approaches to reducing these emissions while expanding production presents a major challenge to the agricultural research community

    2011-01-01

    Full Text Available Abstract Background Alcohol and drug use is known to be a major factor affecting the incidence of traumatic injury. However, the ways in which immediate pre-injury substance use affects patients' clinical care and outcomes remains unclear. The goal of the present study is to determine the associations between pre-injury use of alcohol or drugs and patient injury severity, hospital course, and clinical outcome. Materials and methods This study used more than 200,000 records from the National Trauma Data Bank (NTDB, which is the largest trauma registry in the United States. Incidents in the NTDB were placed into one of four classes: alcohol related, drug related, alcohol-and-drug related, and substance negative. Logistic regression models were used to determine comorbid conditions or treatment complications that were significantly associated with pre-injury substance use. Hospital charges were associated with the presence or absence of drugs and alcohol, and patient outcomes were assessed using discharge disposition as delimited by the NTDB. Results The rates of complications arising during treatment were 8.3, 10.9, 9.9 and 8.6 per one hundred incidents in the alcohol related, drug related, alcohol-and-drug related, and substance-negative classes, respectively. Regression models suggested that pre-injury alcohol use is associated with a 15% higher risk of infection, whereas pre-injury drug use is associated with a 30% higher risk of infection. Pre-injury substance use did not appear to significantly impact clinical outcomes following treatment for traumatic injury, however. Conclusion This study suggests that pre-injury drug use is associated with a significantly higher complication rate. In particular, infection during hospitalization is a significant risk for both alcohol and drug related trauma visits, and drug-related trauma incidents are associated with increased risk for additional circulatory complications. Although drug and alcohol related

  2. Assessing agricultural management effects on structure related soil hydraulic properties by tension infiltrometry

    2009-04-01

    Soil structure is a dynamic property subject to numerous natural and human influences. It is recognized as fundamental for sustainable functioning of soil. Therefore knowledge of management impacts on the sensitive structural states of soil is decisive in order to avoid soil degradation. The stabilization of the soil's (macro)pore system and eventually the improvement of its infiltrability are essential to avoid runoff and soil erosion, particularly in view of an increasing probability of intense rainfall events. However structure-related soil properties generally have a high natural spatiotemporal variability that interacts with the potential influence of agricultural land use. This complicates a clear determination of management vs. environmental effects and requires adequate measurement methods, allowing a sufficient spatiotemporal resolution to estimate the impact of the targeted management factors within the natural dynamics of soil structure. A common method to assess structure-related soil hydraulic properties is tension infiltrometry. A major advantage of tension infiltrometer measurements is that no or only minimum soil disturbance is necessary and several structure-controlled water transmission properties can readily be derived. The method is more time- and cost-efficient compared to laboratory measurements of soil hydraulic properties, thus enabling more replications. Furthermore in situ measurements of hydraulic properties generally allow a more accurate reproduction of field soil water dynamics. The present study analyses the impact of two common agricultural management options on structure related hydraulic properties based on tension infiltrometer measurements. Its focus is the identification of the role of management within the natural spatiotemporal variability, particularly in respect to seasonal temporal dynamics. Two management approaches are analysed, (i) cover cropping as a "plant-based" agro-environmental measure, and (ii) tillage with

    AIM: To evaluate properties of bone quantity/quality using young non-obese Type 1 (T1D)-diabetic (NOD) prone and syngenic non-diabetic (NOD.scid) mice. METHODS: Quantitative bone assessment of tibia was conducted using dual-energy X-ray absorptiometry (DXA) for the evaluation of body mass, bone mineral content, body fat mass and lean mass. Qualitative assessment was accomplished by three-point breakage for assessment of force to failure and micro-computed tomography for evaluation of trabecular and cortical properties of bone. In addition, fasting blood was evaluated prior to sacrifice at week eleven and fifteen to evaluate and compare glucose homeostasis between the strains of mice. RESULTS: Our findings support a perturbation in the relationship between bone quantity, quality, and subsequently, the association between structure and strength. There were no differences in DXA-assessed body composition (body fat, % fat mass and lean mass) and bone composition (bone mineral content and bone mineral density) between strains. However, relative to NOD.scid, NOD mice had lower trabecular bone volume, relative trabecular bone volume, trabecular number and trabecular total material density (P < 0.05). Conversely, NOD mice had greater cortical total mean volume (P < 0.05). General linear models analysis adjusted for body weight revealed a significant contribution of T1D to bone health as early as 5 wk. CONCLUSION: It is well-established that diabetes is a significant risk factor for increased fractures, although the underlying mechanisms are not fully understood. Investigation of bone parameters encompassing strength and structure early in the life course will facilitate the elucidation of the pathogenesis of impaired bone integrity. PMID:23961325

    Full Text Available In the Ecuadorian province of Azuay, agro-ecology seems to signal towards the rebirth of family agriculture in a context of regional migration. Given changes in land usage and the improvement of peasant economies, we envisage a profound mutation in the rural landscape of Azuay. Notwithstanding, in lieu of a true model of territorial rural development, the term territorial resistance is used as weak regional commercial networks do not allow an adequate integration of a majority of peasants, evidencing the need for a more ambitious vision that takes into account the close ties between rural and urban areas, to assist the insertion of poor peasant farmers into commercial agriculture.

    2005-06-01

    This study compared students' academic procrastination tendency with the (1) frequency and nature of rationalizations used to justify procrastination, (2) self-regulation, and (3) performance in a web-based study strategies course with frequent performance deadlines. 106 college students completed the 16-item Tuckman Procrastination Scale, a measure of tendency to procrastinate, the Frequency of Use Self-survey of Rationalizations for Procrastination, and a 9-item self-regulation scale. Students' subsequent course performance was measured by total points earned. A linear regression with Academic Procrastination as the criterion variable and Rationalization score and Course Points as the predictor variables suggested academic procrastinators support procrastinating by rationalizing, not self-regulating, and thus put themselves at a disadvantage, with respect to evaluation in highly structured courses with frequent enforced deadlines.

    Full Text Available Abstract Background Medical students report high levels of stress related to their medical training as well as to other personal and financial factors. The aim of this study is to investigate whether there are differences in course-related stressors reported by medical students on undergraduate problem-based learning (PBL and non-PBL programmes in the UK. Method A cross-sectional study of second-year medical students in two UK medical schools (one PBL and one non-PBL programme was conducted. A 16-question self-report questionnaire, derived from the Perceived Medical Student Stress Scale and the Higher Education Stress Inventory, was used to measure course-related stressors. Following univariate analysis of each stressor between groups, multivariate logistic regression was used to determine which stressors were the best predictors of each course type, while controlling for socio-demographic differences between the groups. Results A total of 280 students responded. Compared to the non-PBL students (N = 197, the PBL students (N = 83 were significantly more likely to agree that: they did not know what the faculty expected of them (Odds Ratio (OR = 0.38, p = 0.03; there were too many small group sessions facilitated only by students resulting in an unclear curriculum (OR = 0.04, p Conclusion There are significant differences in the perceived course-related stressors affecting medical students on PBL and non-PBL programmes. Course designers and student support services should therefore tailor their work to minimise, or help students cope with, the specific stressors on each course type to ensure optimum learning and wellbeing among our future doctors.

    Full Text Available Abstract Background Optical indicators of cytosolic calcium levels have become important experimental tools in systems and cellular neuroscience. Indicators are known to interfere with intracellular calcium levels by acting as additional buffers, and this may strongly alter the time-course of various dynamical variables to be measured. Results By investigating the underlying reaction kinetics, we show that in some ranges of kinetic parameters one can explicitly link the time dependent indicator signal to the time-course of the calcium influx, and thus, to the unperturbed calcium level had there been no indicator in the cell.

    2016-01-01

    Massively open online courses (MOOCs) are becoming increasingly popular ways to reach diverse lifelong learners all over the world. Although MOOCs resemble more formal classes (e.g. videos of content, quizzes, activities), they are often used by informal audiences from home. Recently, MOOCs have become more utilized by universities to conduct outreach as they explore how to use MOOCs to reach new potential learners. Despite the rapid adaption of MOOCs, little is known about individuals who choose to take a MOOC, how they interact with the course materials, and what motivates them to finish the course.We present results of a study of lifelong learners engaged in an astronomy "101" MOOC. Through analysis of registered learners' behaviors as well as self-reported responses to a survey about science, we were able to characterize a subset of the learners engaged in the MOOC during its first offering. Overall, 25363 learners from over 100 countries registered for the MOOC. Of those, 14900 accessed at least one part of the course. Learners were recruited to complete a survey of their knowledge and attitudes towards science. Of the learner group who opened the course, 2889 individuals completed the survey, 2465 of those were able to be linked to their usage of the MOOC through a unique identifier.Learners represented a wide-range of ages, professions, and previous science experience. The best predictors for MOOC completion were engagement in the first activity and first writing assignment and engagement in the online forum. Learners were very interested in science prior to their registration, had higher basic science knowledge that most undergraduate students enrolled in a parallel astronomy course, and used online searches and science sites to get their information about science. As we reach out to a worldwide audience to learners in these massively open online courses, understanding their motivations and behaviors will be essential. This work is helping us understand and

  9. Soil type as factor controlling the effects of forest transformation to agricultural use in soil aggregation and related properties

    The stability of aggregates has an important role in soil functioning and its behavior to avoid erosion and degradation, the ability to transfer liquids and gases, which are important features for crop production and ecosystem health (Tisdall and Oades, 1982). It's also a property that is highly influenced by land use and management (Angers et al., 1993). The stability of aggregates provides key information about the capacity of soil functions that defines the soil quality. This study has aimed to identify the long-term effects of forest transformation on agricultural use on soil structure and related properties. For the research was chosen seven localities in the Alicante Province (E Spain) with different soil types in all cases to compare how the land use changes can affect as a function of soil type and characteristics. In every site, samples were collected from agricultural land use (dry crops with tillage management), and in forest areas close to them with similar soil type that are used as references. On the samples, selected physical and chemical properties were analyzed such as Soil aggregate stability (AS), Organic matter (OM), Mean weight diameter (MWD) of aggregates and Water repellency (WR). As expected, in all cases the AS was significant lower in agricultural sites than in forest. But in some cases the differences were much higher than in others. In forest sites the AS varied between 46 to 82% while in agricultural sites ranged between 14 to 45%. The results showed strong positive correlation of AS with OM. The lowest initial values of AS were found in wettable sandy soils. The agricultural land use lead to relative decrease in AS by 39 to 79% compared to forest soils, indicating that some soils are much more vulnerable to land use than others. These differences can be explained mainly because intrinsic soil properties, such as OM content, texture, and WR. Particularly, the decrease in OM content and absence of WR are responsible for the decrease in

    Full Text Available Context Knowledge of variations of the vessels closely related to the pancreas adds greatly to the success of pancreatic surgery. Splenic vein is one of the vessels that are closely related to the pancreas. Its variations might not only change the haemodynamics in the vein but also cause unexpected bleeding during pancreatic surgery. Case report During our dissection classes, we noted the variations in the course and termination of the splenic vein. After emerging from the spleen, it coursed upward and to the right, embedded in a groove on the anterior surface of body of pancreas. After reaching the upper border, it turned downwards and entered the body of the pancreas. After having a downward course in the body of pancreas, it emerged out and united with the superior mesenteric vein at an angle of about 160 degrees to form the portal vein. Conclusion This peculiar course of the vein might predispose it for thrombosis in case of pancreatitis. It can also lead to iatrogenic injuries during pancreatic or splenic surgeries.

  15. Trends in atmospheric ammonium concentrations in relation to atmospheric sulfate and local agriculture

    International Nuclear Information System (INIS)

    Ammonium (NH4+) concentrations in air and precipitation at the Institute of Ecosystem Studies (IES) in southeastern New York, USA declined over an 11-year period from 1988 to 1999, but increased from 1999 to 2001. These trends in particulate NH4+ correlated well with trends in particulate SO42- over the 1988-2001 period. The NH4+ trends were not as well correlated with local cattle and milk production, which declined continuously throughout the period. This suggests that regional transport of SO42- may have a greater impact on concentrations of NH4+ and subsequent deposition than local agricultural emissions of NH3. Ammonium concentrations in precipitation correlated significantly with precipitation SO42- concentrations for the 1984-2001 period although NH4+ in precipitation increased after 1999 and SO42- in precipitation continued to decline after 1999. The correlation between NH4+ and SO42- was stronger for particulates than for precipitation. Particulate NH4+ concentrations were also correlated with particulate SO42- concentrations at 31 of 35 eastern U.S. CASTNet sites that had at least 10 years of data. Air concentrations of NH4+ and SO42- were more strongly correlated at the sites that were located within an agricultural landscape than in forested sites. At most of the sites there was either no trend or a decrease in NH4+ dry deposition during the 1988-2001 period. The sites that showed an increasing trend in NH4+ dry deposition were generally located in the southeastern U.S. The results of this study suggest that, in the northeastern U.S., air concentrations of NH4+ and subsequent deposition may be more closely linked to SO42- and thus SO2 emissions than with NH3 emissions. These results also suggest that reductions in S emissions have reduced NH4+ transport to and NH4+-N deposition in the Northeast. - Relationships between NH4+ and SO42- suggest that aerosol NH4+ may be more strongly linked to SO2 emissions than to local agricultural NH3 emissions

    Full Text Available A study was conducted to identify the campers’ backgrounds and their recreation participation pattern in camping site at Shah Alam Agriculture Park, Selangor. The study has found that the campers were comprised of well-educated youths with tertiary education background. They usually came during festive holiday break with their friends and most of them are the first time visitors. The results also indicated that most of them valued the natural beauty, cleanliness and maintenance in campsite, safety and friendly staff of the park. The main purpose of camping is to enjoy and experiencing nature, escape from daily stress and learning of new experience. In overall, it shows that the campers’ dynamics where their emphasis on the naturalness, cleanliness as well as provision of more activities (especially activities involving family recreation or group leadership camping programs and facilities (using actually tent instead of chalet would be the criteria to attract campers to this park.

  17. Assessing the co-occurrence of intimate partner violence domains across the life-course: relating typologies to mental health

    2014-09-01

    Full Text Available Background: The inter-generational transmission of violence (ITV hypothesis and polyvictimisation have been studied extensively. The extant evidence suggests that individuals from violent families are at increased risk of subsequent intimate partner violence (IPV and that a proportion of individuals experience victimisation across multiple rather than single IPV domains. Both ITV and polyvictimisation are shown to increase the risk of psychiatric morbidity, alcohol use, and anger expression. Objective: The current study aimed to 1 ascertain if underlying typologies of victimisation across the life-course and over multiple victimisation domains were present and 2 ascertain if groupings differed on mean scores of posttraumatic stress disorder (PTSD, depression, alcohol use, and anger expression. Method: University students (N=318 were queried in relation to victimisation experiences and psychological well-being. Responses across multiple domains of IPV spanning the life-course were used in a latent profile analysis. ANOVA was subsequently used to determine if profiles differed in their mean scores on PTSD, depression, alcohol use, and anger expression. Results: Three distinct profiles were identified; one of which comprised individuals who experienced “life-course polyvictimisation,” another showing individuals who experienced “witnessing parental victimisation,” and one which experienced “psychological victimisation only.” Life-course polyvictims scored the highest across most assessed measures. Conclusion: Witnessing severe physical aggression and injury in parental relationships as a child has an interesting impact on the ITV into adolescence and adulthood. Life-course polyvictims are shown to experience increased levels of psychiatric morbidity and issues with alcohol misuse and anger expression.

  18. Clinical course over two to six years of age-related macular degeneration with or without radiation

    International Nuclear Information System (INIS)

    We previously reported about the long-term outcome as long as three years after radiation therapy for choroidal neovascularization secondary to age-related macular degeneration (AMD). Though MPS (Macular Photocoagulation Study) Group reported the long-term natural course of AMD, such reports have not been provided concerned about Japanese AMD patients. Furthermore, there is not report that revealed the course of AMD with radiation therapy more than three years. We evaluated the long-term natural course and long-term effect of low-dose radiation on AMD. The fundus ophthalmoscopic evaluation and visual outcome were compared retrospectively among control group and two treated groups; seven eyes received 10 Gy, and eight eyes 20 Gy. The control group consisted of 10 eyes without treatment. All patients were followed at least four years, and the average follow-up duration was 6.56 years. The course of median visual acuity without treatment showed the similar result to that of MPS Group's report. In control group, visual acuity (VA) after four years was better in no eyes, unchanged in two eyes, and worse in eight eyes; in treated group, better in four eyes, unchanged in one eye, and worse in ten eyes. After four years VA was kept 20/200 or higher in 2 eyes without treatment, 4 eyes with 10 Gy, and 4 eyes with 20 Gy of radiation. Then maximum VA was 20/125 with no treatment, and 20/50 with radiation therapy. The natural course of the AMD of Japanese patients showed similar results to US patients. All eyes of AMD withort treatment got worse in VA, and some showed better outcome with radiation therapy; but it was not statistically significant. (author)

    2016-01-01

    The aim of this study was to investigate how landscape disturbance associated with roads, agriculture and forestry influenced temporal patterns in woylie (Bettongia penicillata) abundance before, during and after periods of rapid population change. Data were collected from an area of approximately 140,000 ha of forest within the Upper Warren region in south-western Australia. Woylie abundance was measured using cage trapping at 22 grid and five transect locations with varying degrees of landscape disturbance between 1994 and 2012. We found evidence that the distribution and abundance of woylies over time appears to be related to the degree of fragmentation by roads and proximity to agriculture. Sites furthest from agriculture supported a greater abundance of woylies and had slower rates of population decline. Sites with fewer roads had a greater abundance of woylies generally and a greater rate of increase in abundance after the implementation of invasive predator control. The results of this study suggest that landscape disturbance is less important at peak population densities, but during times of environmental and population change, sites less dissected by roads and agriculture better support woylie populations. This may be due to the role these factors play in increasing the vulnerability of woylies to introduced predators, population fragmentation, weed species invasion, mortality from road collisions or a reduction in available habitat. Strategies that reduce the impact of disturbance on woylie populations could include the rationalisation of forest tracks and consolidation of contiguous habitat through the acquisition of private property. Reducing the impact of disturbance in the Upper Warren region could improve the resilience of this critically important woylie population during future environmental change. PMID:27501320

    2008-01-01

    Full Text Available The growth of accredited postgraduate courses in public relations highlights the need for research that explores the motivations and career expectations of postgraduate students.Australian and international research suggests that undergraduate student expectations differ from the realities of courses and careers in public relations (Bowen, 2003; Storto, 1990; Xavier, Mehta & Larkin, 2006.Undergraduate students favour training in publicity and promotion more than the critical thinking and business skills preferred by employers (Bowen, 2003. The gap between perception and reality has the potential to affect the continued development of public relations as a management function.Using international research as its base, this study explores the Australian postgraduate perspective through a survey of approximately 140 students to identify their motivations to study public relations and preferences for positions and workplace environments.The survey was administered in an introductory postgraduate public relations theory unit across four consecutive semesters during 2004 and 2005. The findings provide insight into the career expectations of postgraduate students who prefer careers in event management and publicity. Educators must balance student needs with university teaching and learning goals and industry expectations by preparing students for the diversity of careers in public relations.

    2014-01-01

    The purpose of this study was to provide a formative needs assessment of Diné (Navajo) parents for the prevention of childhood injuries resulting from livestock and horses. The research objectives were to identify parents' perceived livestock and horse related injury risks to Diné children and describe Diné community stakeholder input on prevention interventions for reducing injury risks to children associated with livestock and horse related activities on farms or ranches. The assessment used a survey constructed of closed and open-response questions to gauge Diné farmers' and ranchers' perceptions of injury risks to children who live or work on agricultural operations. Additional questions were asked to gauge Diné acceptance of an online training program as a prevention intervention to reduce livestock and horse related injuries to children. A total of 96 individuals agreed to participate in the survey and provided usable responses. A total of 53.2% (f = 50) of participants were female. Sixty-three percent of participants (f = 58) perceived that youth who work with intact male livestock were at high risk for injury. A total of 25 individuals perceived that youth who ride horses without equestrian helmets were at high risk for injury. Approximately 96% (f = 89) of those surveyed agreed or strongly agreed that they would use an online training program to promote agricultural health and safety for Diné youth. When participants were asked if there were safety issues associated with having youth working on a farm or ranch, a very large portion felt that the biggest issue was a lack of education and instruction from elders. A recommendation for an injury prevention practice included developing a user-friendly online network, giving parents and community leaders access to resources to assist in educating youth in local agricultural traditions integrated with safety training.

    Terraced landscapes are one of the most obvious human-shaped landscapes, mainly used to reduce the negative impact of soil erosion due to uncontrolled runoff and shallow landslides occurrence. Nevertheless, as the recent literature emphasizes, these old best practices can transform into a potential hazard for soil degradation, if not appropriately maintained. In Moldavian Plateau (NE Romania), agricultural terraces were built after the 1960s for landslide, soil erosion and runoff control, mainly in connection with construction of reservoirs, for increasing their operation time. Usually, the slope reduction was obtained by construction of cut-off ditches, hillside ditches, intermittent terraces, bench terraces, broad-based terraces, vineyardand orchard terraces. Due to the dry climatic setting, to the lack of hard rocks for construction, and to the generally light earth moving machinery available for construction, terraces are generally characterized by a small escarpment (0.5m to 1m), and a relatively short lateral extension (5 to 40 m). When the terraces were maintained, the backslope was typically covered with grass. When, after the 1990s, the lands were returned to the initial owners, the vegetation cover of the terraces was no more maintained, and the terraces themselves were progressively abandoned, due to lack of funds. Accurate landslide mapping on high resolution LiDAR DEM derived images, allowed to produce geomorphological inventories in 5 test cases, representative of the whole study area. In each inventory, landslides were classified based on type and relative age based on published classification schemes. We investigate the spatial and temporal relation between landslides occurrence and terraces, based on the spatial interactions of landslides of different ages and terraces. Results reveal that terraces were built, both on landslide-free and landslide-bearing slopes, and that frequently landslides and gullies develop on terraced slopes. Reactivations of

  6. The impact of climate change on agriculture and related resources in the Great Plains

    International Nuclear Information System (INIS)

    The impacts of climate change on water resources and agriculture in the four Great Plains states Missouri, Iowa, Nebraska and Kansas (MINK), using the anomalously hot and dry weather of the 1930s as a model for climate in the year 2030 and a mechanistic crop simulation model known as the Erosion Productivity Impact Calculator (EPIC), are described. EPIC was modified for climate impact analysis by compiling data sets providing detailed descriptions of farms representative of the MINK region, representing the effect of increased carbon dioxide on crop water use and photosynthetic efficiency, and incorporating daily temperature and precipitation data, monthly solar radiation and humidity levels. Technologies assumed to become available include advances in breeding and biotechnology to increase harvest index, boosting of photosynthetic efficiency, and advances in pest management. If no technological adjustment was incorporated, corn yielded 20% less than baseline, soybeans 15% less and sorghum 8% less. Wheat and alfalfa yielded slightly higher. Incorporation of technological advances greatly reduced negative effects of climate change, with yields raised above baseline for every crop but corn

  7. Impact of pedoclimatic and agricultural conditions on sunflower seeds characteristics in relation to the dehulling process

    Full Text Available Dehulling sunflower seeds can increase meal protein content by up to 35–36%. However, high variability in seed quality constitutes an obstacle to optimizing the dehulling process. This study has sought to identify the parameters that influence the protein content of sunflower seeds and the ease with which they can be dehulled. Genetic, climatic and crop management effects were studied using seed samples taken from farmers’ fields in south-west France. Soil and climatic effects were revealed to be important for protein content and ease of dehulling (hullability. Some cultivars were found to be significantly more difficult to dehull than others. No relationship was observed between oil content and protein content expressed as a proportion of DDM (defatted dry matter, but there was a significant negative linear relationship between hullability and oil content. Due to the wide range of locations and agricultural practices encountered in the farmers’ fields, it was not possible to verify with confidence the influence of other interactions such as nitrogen fertilization and the potential fertility of the fields. This work nevertheless showed that locality and growing conditions affect the quality of sunflower seeds. This variability in quality could be measured by crushers in order to optimize the dehulling process and thereby produce a meal of consistent quality, with a guaranteed protein content.

  8. Aspects of soil organic matter and nutrient cycling in relation to climate change and agricultural sustainability

    International Nuclear Information System (INIS)

    The role of the world's soils and their organic matter content is highlighted against the backdrop of an anticipated anthropogenic climate change. Contrary to many recent publications, it is argued that the hazards of their degradation, under a transient scenario of global change, may diminish rather than increase. Terrestrial carbon sequestration, through the buildup of organic matter in soils, makes sense in its own right. Possibilities for restoring depleted organic matter levels are reviewed and special attention is given to historic examples of sustained doubling of soil carbon content, both in northwestern Europe and in the tropics. A plea is made to carry out research on the processes that have caused such a sustainable improvement in soil fertility with a view to emulating this for soils of the moist savannah zones of sub-Saharan Africa. A proposal is then made to make this operational in the onchocerciasis freed zone of West Africa, in combination with a recent World Bank initiative for large scale rock phosphate applications in tropical soils as a capital investment in integrated natural resources management - as a 'win-win' situation of increasing agricultural productivity in developing countries and of protecting global environmental conditions.

    Full Text Available In this article an attempt was made to analyse the stock, output, and incomes in individual agricultural farms in Poland, in comparison with farms from the other EU countries in the year 2006. Research was based on the FADN database. The research showed, that (among other things the Polish average individual farm had a four time lower the balance’s sum than the medium one in the EU, and the average output and family farm income were about three times lower in Poland than the average in the Union. The highest share of stock in the balance’s sum in Poland three direction of production had: permanent crops combined, specialist other field crops and specialist orchards – fruits. While in the Union the highest stock had the specialist wine. According to the regression’s models, in Poland the positive influence on the increase of family farm income had stock, crops and livestock output. In the Union positive influence on an income’s growth had crops and livestock production and negative influence had the stock.

    A survey Of "top" wheat farmers in 12 counties in western Nebraska was undertaken to help guide future research and extension programs (in agricultural meteorology and economics) in the region. One hundred forty-two farmers (59 percent of those receiving questionnaires) responded to the survey. Of the respondents, 42 percent own or are considering purchasing a personal computer; the vast majority of farmers own a rain gage and some form of temperature- measuring device; the respondents were moderately familiar with an existing Automated Weather Data Network in Nebraska; commercial and NOAA weather radio and commercial television are the main sources of weather data and information. short-term weather forecasts (1 day and 3-5 days) are most important to overall farm planning; respondents considered market and cost-of-production information and more-accurate weather forecasts most important in better management of their farm operations; the risk factors that impacted farm net income were economic followed by weather factors and marketing decisions; and most farmers would be willing to forward contract before the crop was half developed if good projections of crop status and yield could be made. A major constraint to preharvest forward contracting from some of the farmers' perspective appears to be variability in yield due to hail.

    Observations led to the selection of the alfalfa dehydration industry for in-depth analysis of the application of moderate-temperature geothermal heat. Six geothermal heat exchanger/dryer configurations were examined. A low-temperature conveyor dryer using geothermal water to supply all required heat was chosen for site-specific analysis, the retrofitting of a large alfalfa dehydration plant within the Heber KGRA in the Imperial Valley, California. Even in the most favorable scenario--sharing a geothermal pipeline with the neighboring fertilizer plant--geothermal retrofitting would increase the price of the alfalfa ''dehy'' about 40 percent. The geothermal brine is estimated to cost $2.58/million Btu's compared with a 1977 natural gas cost of $1.15. Capital cost for heat exchangers and the new dryers is estimated at $3.3 million. The Heber plant appeared to offer the only good opportunity for geothermal retrofitting of an existing alfalfa dehydration plant. Construction of new plants at geothermal resource sites cannot be justified due to the uncertain state of the ''dehy'' industry. Use of geothermal heat for drying other crops may be much more promising. The potato dehydration industry, which is concentrated in the geothermal-rich Snake River Valley of Idaho, appears to offer good potential for geothermal retrofitting; about 4.7 x 10{sup 12}Btu's are used annually by plants within 50 miles of resources. Drying together at the geothermal wellhead several crops that have interlocking processing seasons and drying-temperature requirements may be quite attractive. The best ''multicrop drying center'' site identified was at Power Ranch Wells, Arizona; 34 other sites were defined. Agricultural processing applications other than drying were investigated briefly.

    Ecological changes associated with anthropogenic ecosystem disturbances can influence human risk of exposure to malaria and other vector-borne infectious diseases. This study in Mwea, Kenya, investigated the pattern of insecticide use in irrigated and nonirrigated agroecosystems and association with the density, survival, and blood-feeding behavior of the malaria vector Anopheles arabiensis. The parity rates of adult An. arabiensis from randomly selected houses were determined by examining their ovaries for tracheal distension, and polymerase chain reaction was used to identify the host blood meals. In addition, structured questionnaires were used to generate data on insecticide use. Anopheles arabiensis densities were highest in irrigated rice agroecosystems, intermediate in irrigated French beans agroecosystems, and lowest in the nonirrigated agroecosystem. Anopheles arabiensis adult survivorship was significantly lower in irrigated rice agroecosystems than in irrigated French beans agroecosystems. The human blood index (HBI) was significantly higher in the nonirrigated agroecosystem compared to irrigated agroecosystems. Moreover, there was marked variation in HBI among villages in irrigated agroecosystems with significantly lower HBI in Kangichiri and Mathangauta compared to Kiuria, Karima, and Kangai. The proportion of mosquitoes with mixed blood meals varied among villages ranging from 0.25 in Kangichiri to 0.83 in Kiuria. Sumithion, dimethoate, and alpha cypermethrin were the most commonly used insecticides. The 1st was used mostly in irrigated rice agroecosystems, and the last 2 were used mostly in irrigated French beans agroecosystems. These findings indicate that agricultural practices may influence the ecology and behavior of malaria vectors and ultimately the risk of malaria transmission. PMID:24199496

    The amount of evapotranspiration (ET) to the atmosphere can account for 60% or more of the water loss in many semi-arid locations, and can critically affect local economies tied to agriculture, recreation, hydroelectric power, ecosystems, and numerous other water-related areas. NASA supports many activities using satellite and Earth science data to more accurately and cost effectively estimate ET. NASA ET related work includes the research, development and application of techniques. The free and open access of NASA satellite data and products now permits a much wider application of ET mapping. Typically the NASA supported approaches ranges from large regional and continental ET mapping using MODIS (also with AIRS and CERES), GRACE (gravimetric water balance), geostationary (e.g., GOES and Meteosat for near continental sca|e), land surface modeling (i.e, Land Data Assimilation Systems) to fine scale mapping such as provided bvLandsatdata(agriculture with an emphasis on the Western U3.. This summary includes a description of ET projects in the Middle Rio Grande, Yakima, North Platte and other selected basins in the western US. We will also discuss plans to further address ET applications through working with the USDA and the Group on Earth Observations (GEO) to extend and evaluate western U.S. ET mapping to other parts of the U.S. and internationally.

  14. Legumes increase rhizosphere carbon and nitrogen relative to cereals in California agricultural plots

    2013-12-01

    Nitrogen (N) is an essential nutrient to plant growth, therefore a sufficient supply is needed for high yields. By using N-fixing plants like legumes in crop rotation, we can increase soil N and yields of following crops. Furthermore, legumes also affect soil carbon (C) and C:N ratios, which impacts nutrient cycling in soils. We assessed the effects of two legumes (vetch, fava bean) and a cereal mixture (oats and wheat) on soil N and C by comparing both rhizosphere and bulk soils. We studied the impacts of these plants with different management types (organic, low-input conventional, unfertilized) to see if plant effects on soil C and N changed across management. We used plots from the Long-Term Research on Agricultural Systems (LTRAS) experiment (Davis, CA) to conduct this experiment, where three plots were under each management type. Within each of these plots, we sampled three micro-plots, where we collected rhizosphere soil from fava bean, vetch, and cereals as well as bulk soil, i.e. non-rhizosphere soil. We collected 108 samples, each of which were dried and ball-milled into a fine, uniform powder. Tin capsules with 15-30mg of soil were then analyzed with a Carlo Erba Elemental analyzer to measure how much N and C was present in each of the samples. The different management types didn't affect the relationship among plants, but soil C and N were highest in organic and lowest in unfertilized plots. We found that N was significantly higher in legume rhizosphere than cereal rhizosphere and bulk soils. Soil C was also higher in legumes vs. cereals and bulk soils, but the only significant difference was with the bulk soils. This ultimately resulted in lower C:N ratios in the rhizosphere of legumes, only vetch, however, had significantly lower soil C:N than cereals. Vetch had higher N, and lower C and C:N than fava bean, but the difference between the two legumes was never significant. Similarly, cereals had higher C and N and lower C:N than bulk soils, although

    Mega-fauna (defined as animals > 44 kg) experienced a global extinction with 97 of 150 genera going extinct by {approx} 10 000 years ago. We estimate the net primary production (NPP) that was liberated following the global extinction of these mega-herbivores. We then explore how humans, through agriculture, gradually appropriated this liberated NPP, with specific calculations for 800, 1850, and 2000 AD. By 1850, most of the liberated NPP had been appropriated by people, but NPP was still available in the Western US, South America and Australia. NPP liberated following the extinction of the mega-herbivores was {approx} 2.5% ({approx}1.4 (between 1.2 and 1.6) Pg yr{sup -1} of 56 Pg C yr{sup -1}; Pg: petagrams) of global terrestrial NPP. Liberated NPP peaked during the onset of agriculture and was sufficient for sustaining human agriculture until {approx} 320 (250-500) years ago. Humans currently use {approx} 6 times more NPP than was utilized by the extinct Pleistocene mega-herbivores.

    Previous research had shown that three closely related species of Lysobacter, i.e., Lysobacter antibioticus, Lysobacter capsici, and Lysobacter gummosus, were present in different Rhizoctonia-suppressive soils. However, the population dynamics of these three Lysobacter spp. in different habitats remains unknown. Therefore, a specific primer-probe combination was designed for the combined quantification of these three Lysobacter spp. using TaqMan. Strains of the three target species were efficiently detected with TaqMan, whereas related non-target strains of Lysobacter enzymogenes and Xanthomonas campestris were not or only weakly amplified. Indigenous Lysobacter populations were analyzed in soils of 10 organic farms in the Netherlands during three subsequent years with TaqMan. These soils differed in soil characteristics and crop rotation. Additionally, Lysobacter populations in rhizosphere and bulk soil of different crops on one of these farms were studied. In acid sandy soils low Lysobacter populations were present, whereas pH neutral clay soils contained high populations (respectively, <4.0-5.87 and 6.22-6.95 log gene copy numbers g(-1) soil). Clay content, pH and C/N ratio, but not organic matter content in soil, correlated with higher Lysobacter populations. Unexpectedly, different crops did not significantly influence population size of the three Lysobacter spp. and their populations were barely higher in rhizosphere than in bulk soil. PMID:21448673

    Complex associations exist among socioeconomic status (SES) in early life, beliefs about oral health care (held by individuals and their parents), and oral health-related behaviors. The pathways to poor adult oral health are difficult to model and describe, especially due to a lack of longitudinal data. The study aim was to explore possible pathways of oral health from birth to adulthood (age 38 y). We hypothesized that higher socioeconomic position in childhood would predict favorable oral health beliefs in adolescence and early adulthood, which in turn would predict favorable self-care and dental attendance behaviors; those would lead to lower dental caries experience and better self-reported oral health by age 38 y. A generalized structural equation modeling approach was used to investigate the relationship among oral health-related beliefs, behaviors in early adulthood, and dental health outcomes and quality of life in adulthood (age, 38 y), based on longitudinal data from a population-based birth cohort. The current investigation utilized prospectively collected data on early (up to 15 y) and adult (26 and 32 y) SES, oral health-related beliefs (15, 26, and 32 y), self-care behaviors (15, 28, and 32 y), oral health outcomes (e.g., number of carious and missing tooth surfaces), and oral health-related quality of life (38 y). Early SES and parental oral health-related beliefs were associated with the study members' oral health-related beliefs, which in turn predicted toothbrushing and dental service use. Toothbrushing and dental service use were associated with the number of untreated carious and missing tooth surfaces in adulthood. The number of untreated carious and missing tooth surfaces were associated with oral health-related quality of life. Oral health toward the end of the fourth decade of life is associated with intergenerational factors and various aspects of people's beliefs, SES, dental attendance, and self-care operating since the childhood years

    Full Text Available One of the most important issues affecting future world is managing the existing water resources. There is no doubt that global warming has created significant troubles on people's lives and it has caused shortage of water in the world. Therefore, we need to manage the water resources by allocating appropriate methods. In this paper, we use data envelopment analysis to measure the relative efficiency of fourteen different irrigation methods. The proposed model of this paper uses four inputs including cost, risk, maintenance and expertise and two outputs including flexibility and durability of irrigation methods. The preliminary results indicate that two surface irrigation methods, one sprinkler irrigation method and one subsurface irrigation technique are considered efficient. Other irrigation techniques are only as much as 50 to 94 percent efficient compared with these five irrigation techniques

    Denis Fargette

    Full Text Available The mechanisms of evolution of plant viruses are being unraveled, yet the timescale of their evolution remains an enigma. To address this critical issue, the divergence time of plant viruses at the intra- and inter-specific levels was assessed. The time of the most recent common ancestor (TMRCA of Rice yellow mottle virus (RYMV; genus Sobemovirus was calculated by a Bayesian coalescent analysis of the coat protein sequences of 253 isolates collected between 1966 and 2006 from all over Africa. It is inferred that RYMV diversified approximately 200 years ago in Africa, i.e., centuries after rice was domesticated or introduced, and decades before epidemics were reported. The divergence time of sobemoviruses and viruses of related genera was subsequently assessed using the age of RYMV under a relaxed molecular clock for calibration. The divergence time between sobemoviruses and related viruses was estimated to be approximately 9,000 years, that between sobemoviruses and poleroviruses approximately 5,000 years, and that among sobemoviruses approximately 3,000 years. The TMRCA of closely related pairs of sobemoviruses, poleroviruses, and luteoviruses was approximately 500 years, which is a measure of the time associated with plant virus speciation. It is concluded that the diversification of RYMV and related viruses has spanned the history of agriculture, from the Neolithic age to the present.

    Atkins, E.L.

    1979-04-01

    PART I: Continuous exposure to 30 ppB H/sub 2/S increased lifespan of caged worker honey bees, Apis mellifera L., 33%; whereas, bees exposed > 13 days to 100 ppB and 300 ppB H/sub 2/S the lifespan was shortened 32% and 51%, respectively, over unexposed bees; bees exposed > 15 days to a combination of 300 ppB H/sub 2/S + 50 ppM CO/sub 2/ the lifespan was shortened 4.4% more that 300 ppB H/sub 2/S alone. The mean temperature and/or relative humidity did not exert a direct effect on the hazard to bees. A continuous exposure to 300 ppB SO/sub 2/ was detrimental to caged worker honey bees; and, a mean temperature of 27.2/sup 0/C was 75.7% more toxic than the same dosage at 16.7/sup 0/C. Worker bee lifespans exposed to 300 ppB SO/sub 2/ at 16.7/sup 0/C were shortened 13.5% and 79%, respectively, compared to unexposed bees. Therefore, both dosage and temperature exert direct effects on the hazards to bees. PART II: The status of the apicultural industry in Imperial County, California, was outlined giving a short characterization of the area in relation to the apicultural industry. Agriculture utilizes 500,000 intensely farmed acres which generated a 11-year average income of $370 million. Over 40 agricultural commodities are produced. The apicultural industry is intimately involved in 25% of the total gross agricultural income. In addition, most of the flora growing in the desert community which comprises the remainder of the county are very important to honey bees by providing sustaining nectar and/or pollen for brood rearing. The bee foraged flora provides substantial bee forage when colonies are located outside of the agriculutral area. It is concluded that geothermal resource development in the Imperial Valley is contemplated to have minimal effects on the apicultural industry.

  17. The teaching of physics and related courses to residents in radiation oncology

    International Nuclear Information System (INIS)

    A survey of physics and related teaching to radiation oncology residents in 21 Canadian cancer centres was undertaken in December 1987 and January 1988. This survey illustrates a very considerable variation in the formal teaching of physics to aspiring radiation oncologists with, for example, the number of hours offered ranging from 40 to 160 in those 10 centres that have a training program. It would appear to be of benefit to radiation oncology residents, those charged with teaching them, and the radiation oncology community as a whole, to develop specific guidelines for this aspect of resident education.

    The amount of evapotranspiration (ET) to the atmosphere can account for 60% or more of the water loss in many semi-arid locations, and can critically affect local economies tied to agriculture, recreation, hydroelectric power, ecosystems, and numerous other water-related areas. NASA supports many activities using satellite and Earth science data to more accurately and cost effectively estimate ET. NASA ET related work includes the research, development and application of techniques. The free and open access of NASA satellite data and products now permits a much wider application of ET mapping. Typically the NASA supported approaches ranges from large regional and continental ET mapping using MODIS (also with AIRS and CERES), GRACE (gravimetric water balance), geostationary (e.g., GOES and Meteosat for near continental sca|e), land surface modeling (i.e, Land Data Assimilation Systems) to fine scale mapping such as provided bvLandsatdata(<100 m). Usually satellite or airborne thermal imagery are used as input to an ET estimated surface energy balance based approach. There are currently several of these ET approaches under development and implementation including 'METRIC', 'SEBS', 'ALEXI/DisALEXI', etc.. One exception is an approach using GRACE satellite data that estimates the terrestrial water storage using gravimetric data over large areas and estimates ET indirectly. Also land surface modeling within the context of data assimilation and integration schemes provides the capability to integrate in situ, ancillary and satellite together to provide a spatially and synoptic estimates of ET also for use to provide for short-term ET predictions. We will summarize NASA related activities contributing to the improved estimation of ET for water management and agriculture with an emphasis on the Western U3.. This summary includes a description of ET projects in the Middle Rio Grande, Yakima, North Platte and other selected basins in the western US. We will also discuss

  19. GLOBALIZATION AND RESPONSE OF LARGE STATED OWNED ENTERPRISES IN AGRICULTURAL RELATED INDUS TRIES: COMPANY CASE STUDIES FROM CENTRAL CHINA

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    By using interview data from three large state-owned enterprises (SOEs) in agriculture related industries, this paper reveals that SOEs in inland area are much slow in response to globalization. Although they pursued some strate gies to adjust themselves, they are far behind the position to utilize the opportunities generated by economic globaliza tion. Most of them are still out of the networks of transnational corporations. The strategies they adopted are quite differ ent from SOEs in the coastal area. They overlook the importance of information infrastructure, well-educated personnel, and collaboration with the competitive leaders in their industries. The lagging situation is related to isolated location, tradi tional culture, and slow progress in enterprise reform. International comparison shows that the case companies did follow the general patterns that globalization promotes extension of company′s networks of linkages but in a rather slow phase. The decision makers should encourage intra-regional linkages between SOEs, between SOEs and private, foreign owned companies, as well as inter-regional linkages among them. The latter appears particularly important given the enlarging gaps between coastal and inland areas.

    While sanitation interventions have focused primarily on child health, women's unique health risks from inadequate sanitation are gaining recognition as a priority issue. This study examines the range of sanitation-related psychosocial stressors during routine sanitation practices in Odisha, India. Between August 2013 and March 2014, we conducted in-depth interviews with 56 women in four life stages: adolescent, newly married, pregnant and established adult women in three settings: urban slums, rural villages and indigenous villages. Using a grounded theory approach, the study team transcribed, translated, coded and discussed interviews using detailed analytic memos to identify and characterize stressors at each life stage and study site. We found that sanitation practices encompassed more than defecation and urination and included carrying water, washing, bathing, menstrual management, and changing clothes. During the course of these activities, women encountered three broad types of stressors-environmental, social, and sexual-the intensity of which were modified by the woman's life stage, living environment, and access to sanitation facilities. Environmental barriers, social factors and fears of sexual violence all contributed to sanitation-related psychosocial stress. Though women responded with small changes to sanitation practices, they were unable to significantly modify their circumstances, notably by achieving adequate privacy for sanitation-related behaviors. A better understanding of the range of causes of stress and adaptive behaviors is needed to inform context-specific, gender-sensitive sanitation interventions. PMID:26164119

  2. Accumulation of Chernobyl radionuclides in agricultural plants during 1986-1988 in relation to contamination conditions and soil characteristics

    International Nuclear Information System (INIS)

    Since August of 1986, the uptake of Chernobyl radionuclides in the soil to plant system has been under observation (monitoring) at a network of agroecological testing sites and sampling grounds in the contaminated provinces in the Ukrainian and Byelorussian Soviet Socialist Republics. The main aim of this monitoring is to determine transfer factors (Kt) for plant produce in relation to environmental conditions (soil type, agrochemical and climatic characteristics, contamination conditions, etc.) and time. The network of sampling grounds or uncultivated meadowlands is included in the monitoring of herbaceous plant contamination. The radionuclide concentrations in the soil layers and in plants (green matter, grain, straw, root crops, tubers, etc.) are measured annually. The amount of precipitation, humidity and other climate and soil characteristics are being compiled on all of the sites and experimental fields. The results of observations, obtained up to October 1988, show that the Kt values fluctuate within wide ranges (by up to two orders of magnitude) and there is no obvious dependence on physical contamination conditions and soil types. The main conclusion is that in order to predict radioactive contamination on a specific individual farm or in a particular agroindustrial region, one must carry out special research into the uptake of Chernobyl radionuclides by agricultural plants under the real conditions prevailing in that farm or region.

    2007-01-01

    The goal of this study was to test the relative effectiveness of morphological measurements and body size in predicting the smolt age of Atlantic salmon Salmo salar and to determine the time course of body size and shape differences between smolt ages. Analyses were conducted on age-0 to age-2 fish that were stocked as fry in the West Brook, Massachusetts and on laboratory-raised age-0 to age-1 fish. Using both body size and shape, we could partition the age-0 fish collected during fall into future early or late smolts, although the predictive ability of body shape was somewhat weaker than that of body size, especially in the laboratory. Classification success averaged 81% (size) and 79% (shape) in the field and 85% (size) and 73% (shape) in the laboratory. Despite differences in smolt age between the field and the laboratory, the relative timing of growth rate differences between future early and late smolts was similar in the field and the laboratory and peaked at 50-60% of development from fry to smolt. While body shape differed between early and late smolts well before smoltification, it did not improve classification based on size alone.

    Full Text Available Diagnostic delay frequently occurs in Crohn's disease (CD patients because of diagnostic limitations. However, diagnostic delay and its related factors remain poorly defined. Therefore, we aimed to identify the predictors associated with diagnostic delay and to evaluate the impact of diagnostic delay on clinical course in a Korean CD patient cohort. We performed a multicenter retrospective analysis of 1,047 CD patients registered in the Crohn's Disease Clinical Network and Cohort study in Korea. The mean interval of diagnostic delay was 16.0 ± 33.1 months. Multivariate analysis showed that older age at diagnosis (≥40 years (p = 0.014, concomitant upper gastrointestinal (UGI disease (p = 0.012 and penetrating disease behavior at diagnosis (p = 0.001 were positively associated with long diagnostic delay (≥18 months. During the longitudinal follow-up, long diagnostic delay was independently predictive of further development of intestinal stenosis (hazard ratio [HR], 1.43; 95% confidence interval [CI], 1.07-1.93; p = 0.017, internal fistulas (HR, 1.62; 95% CI, 1.12-2.33; p = 0.011, and perianal fistulas (HR, 1.38; 95% CI, 1.06-1.80; p = 0.016. However, as for the risk of abscess formation, bowel perforation, and CD-related abdominal surgery, no significant association with diagnostic delay was observed. Older age at diagnosis, UGI involvement, and penetrating behavior are associated with long diagnostic delay in Korean CD patients. Moreover, diagnostic delay is associated with an increased risk of CD-related complications such as intestinal stenosis, internal fistulas, and perianal fistulas.

  10. Agricultural problems

    International Nuclear Information System (INIS)

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

    Soils play an important role in the benefits offered by ecosystems services. In densely populated Switzerland soils are a scarce resource, with high pressure on services ranging from urban expansion to over-utilization. Key change drivers include erosion, soil degradation, land management change and (chemical) pollution, which should be taken into consideration. Therefore there is an emerging need for an integrated, sustainable and efficient system assessing the management of soil and land as a resource. The use of remote sensing can offer spatio-temporal and quantitative information of extended areas. In particular imaging spectroscopy has shown to perfectly complement existing sampling schemes as secondary information for digital soil mapping. Although only the upper-most layer of soil interacts with light when using reflectance spectroscopy, it still can offer valuable information that can be utilized by farmers and decision makers. Fully processed airborne imaging spectrometer data from APEX as well as land cover classification for the agricultural area in Lyss were available. Based on several spectral analysis methods we derived multiple soil properties, including soil organic matter, soil texture, and mineralogy; complemented by vegetation parameters, including leaf area index, chlorophyll content, pigment distribution, and water content. The surface variables were retrieved using a combination of index-based and physically-based retrievals. Soil properties in partly to fully vegetated areas were interpolated using regression kriging based methods. This allowed the continuous assessment of potential soil functions as well as non-contiguous maps of abundances of combined soil and vegetation parameters. Based on a simple regression model we could make a rough estimate of ecosystem services. This provided the opportunity to look at the differences between the interpolated soil function maps and the non-contiguous (but combined) vegetation and soil function maps

  12. Relative Importance of Quality Factors and Determinants in the Selection of Foreign Language Courses in Social Networks

    Danielle Miranda de Oliveira Arruda Gomes

    2015-09-01

    Full Text Available This paper is based on a research of the relative importance of quality factors and determinants for the selection of language courses in a virtual environment, according to Lee e Kozar (2006. The method used was the Analytic Hierarchy Process. A survey was carried out with 200 individuals who had experiences with any type of educational service in the virtual environment. The more significant factor was the system’s quality, followed by the quality of service, the quality of the information, and the quality of a specific vendor. The main sub-factors were responsiveness, response time, navigability, and security. The study concludes that better-structured social networks facilitate purchases and can induce consumers to change their behavior, moving from conventional to virtual environments. The discovery of the quality factor hierarchy for selecting the social network to study languages suggests that the developers should design websites that present more aesthetic, comfortable, and effective educational services provision, in accordance with the consumers’ expectations.

    Full Text Available Abstract Background With evolving evidence of association between tuberculosis (TB and tobacco smoking, recommendations for the inclusion of tobacco cessation interventions in TB care are becoming increasingly important and more widely disseminated. Connecting TB and tobacco cessation interventions has been strongly advocated as this may yield better outcomes. However, no study has documented the impact of such connection on health-related quality of life (HRQoL. The objective of this study was to document the impact of an integrated TB directly observed therapy short-course (DOTS plus smoking cessation intervention (SCI on HRQoL. Methods This was a multi-centered non-randomized controlled study involving 120 TB patients who were current smokers at the time of TB diagnosis in Malaysia. Patients were assigned to either of two groups: the usual TB-DOTS plus SCI (SCIDOTS group or the usual TB-DOTS only (DOTS group. The effect of the novel strategy on HRQoL was measured using EQ-5D questionnaire. Two-way repeated measure ANOVA was used to examine the effects. Results When compared, participants who received the integrated intervention had a better HRQoL than those who received the usual TB care. The SCIDOTS group had a significantly greater increase in EQ-5D utility score than the DOTS group during 6 months follow-up (mean ± SD = 0.98 ± 0.08 vs. 0.91 ± 0.14, p = 0.006. Similarly, the mean scores for EQ-VAS showed a consistently similar trend as the EQ-5D indices, with the scores increasing over the course of TB treatment. Furthermore, for the EQ-VAS, there were significant main effects for group [F (1, 84 = 4.91, p = 0.029, η2 = 0.06], time [F (2, 168 = 139.50, p = 2 = 0.62] and group x time interaction [F (2, 168 = 13.89, p = 2 = 0.14]. Conclusions This study supports the evidence that an integrated TB-tobacco treatment strategy could potentially improve overall quality of life outcomes among TB patients who are smokers.

  17. One model for an integrated math/physics course focusing on electricity and magnetism and related calculus topics

    Science.gov (United States)

    Dunn, Jason W.; Barbanel, Julius

    2000-08-01

    Over the last decade, there has been an increasing, widespread pedagogical interest in developing various types of integrated curricula for science and engineering programs. Over the last three years, a year-long Integrated Math/Physics course has been developed at Union College. This paper will focus on a model for a one-quarter integrated course organized around a traditional set of electricity and magnetism (E&M) physics topics, integrated with appropriate mathematical topics. Traditional, nonintegrated E&M physics students often struggle with challenging vector calculus ideas which may have been forgotten, not yet encountered, or introduced with different notation in different contexts. Likewise, traditional vector calculus mathematics students are often unable to gain intuitive insight, or fail to grasp the physical significance of many of the vector calculus ideas they are learning. Many of these frustrations are due to the fact that at many schools, the physics and calculus teachers teaching separate courses probably have little or no idea what their fellow educators are actually doing in these courses. Substantial differences in context, notation, and philosophy can cause breakdowns in the transfer of knowledge between mathematics and physics courses. We will discuss the methods, philosophy, and implementation of our course, and then go on to present what we feel were the substantial strengths and insights gained from a thoughtful integration of the two subjects. In addition, some problem areas and recommendations for probable student difficulties will be addressed.

    Full Text Available The need to increase food production for a growing world population makes an assessment of global agricultural water productivities and virtual water flows important. Using the hydrology and agro-biosphere model LPJmL, we quantify at 0.5° resolution the blue (irrigation water and green (precipitation water virtual water content, i.e. the inverse of water productivity, for 11 of the world's major crop types. Based on these, we also quantify the water footprints (WFP of all countries, for the period 1998-2002, distinguishing internal and external WFP (virtual water imported from other countries and their blue and green components, respectively. Moreover, we calculate water savings and losses, and for the first time also land savings and losses, through international trade with these products. The consistent separation of blue and green water flows and footprints, which is needed due to the different sources and opportunity costs of these two water pools, shows that green water globally dominates both the internal and external WFP (84% of the global WFP and 94% of the external WFP rely on green water. Accordingly, some of the major exporters of the crops considered here (e.g. Argentina, Canada export mainly green virtual water, but traditional rice exporters such as India and Pakistan mainly export blue virtual water. The external WFPs are found to be relatively small (6% of the total global blue WFP, 16% of the total global green WFP. Nevertheless, current trade saves significant water volumes and land areas (~263 km3 and ~41 Mha, respectively, equivalent to 5% of the sowing area of the crops considered here and 3.5% of the annual precipitation on this area. Linking the proportions of external to internal blue/green WFP with the per capita WFPs allows recognizing that only a few countries consume more water from abroad than from their own territory and have at the same time above average WFPs. Thus, countries with high levels of per

    Among other skills, a capacity for abstraction and good spatial awareness are needed to succeed in physics courses. According to the prevailing low percentages of passed students on these courses, a great proportion of those students are likely to lack these skills. Our working hypothesis is that simulations could help engineering students visualize physical phenomena and thereby gain a better understanding of physical theoretical concepts and achieve higher grades. Two groups of students (n1 = 40 and n2 = 43) took the same fluid mechanics course at an engineering school. Both groups took the same end-of-course examination, but only group 1 was simulation-taught. For that purpose, 15 original simulations were created with GeoGebra software. Simulation-taught students completed a questionnaire on the interest of using simulations to teach fluid mechanics. Simulations designed in this work covered all the concepts taught on the course and overcame criticisms made on previous simulations also created to teach fluid mechanics. At the examination, the average grade and the percentage of passed students were higher in group 1 than in group 2. When surveyed, group 1 students declared that they enjoyed interacting with the simulations and considered them to be a good complement to the theoretical explanations because simulations helped them revise previously explained concepts. Simulations assisted students with difficulties to visualize and understand physical theoretical concepts but still students performed poorly on the examination. Additional strategies need to be adopted in order to help students develop the skills required to succeed in physics courses.

It received funding from the Swedish National Board of Health and Welfare. It was a continuation of an earlier one-week full-time university course from 2010 with the same title. As a result of a new law relating to refugee reception, which led to organizational change, the participants requested a continuation of the original course. The learning objectives were met (5.4 on a 6-point scale; 1 = strongly disagree, 6 = strongly agree. The general assessment of the course as a whole by the participants was 5.7 (on a 6-point scale, 1 = very unsatisfied, 6 = very satisfied. The participants thought that their skills had increased, and their perception was that they had significantly better control of their work situation following completion of the course. The most important findings were that participants from different agencies at the local level: (1 perceived that they had developed the sense that there was a local inter-cultural and inter-professional inter-agency collaboration in the reception of newly arrived refugees and (2 will continue efforts to stabilize and develop this together. This method of teaching, in terms of skills training, is not a “quick fix.” It is a process, and it needs support from those in power in order to continue.

    Interdependence has always been central to economics but assumes pressing importance for agricultural economists as they deal with industrialising agricultures. Continued unresolvable uncertainties, when properly recognised, also add to the challenge of relevant work in agricultural economics. The related roles of interdependence and uncertainty are illustrated through examples from the progress of agricultural technology and enhancement of food security.

    The report contains the contributions by the Institute of Food and Resource Economics (IFRO) to a Danish Government appraisal of greenhouse gas (GHG) reduction measures. The policy goal is a 40 per cent reduction in total Danish GHG emissions by 2020 compared to 1990. The GHGs analysed in the present study include emissions of CO{sub 2}, nitrous oxide and methane plus soil carbon sequestration. The purpose of the study is to identify GHG mitigation measures related to agriculture which can deliver cost-effective contributions to the targeted reduction in GHG emissions in Denmark. A total of 21 GHG mitigation measures are included in the assessment. The stipulated implementation period is 2013 to 2020. The cost calculations have a time horizon equal to 30 years, i.e. from 2013 to 2042. The GHG reduction potential, expressed in CO{sub 2} equivalents (CO{sub 2}-eq), is calculated as the sum of the effect on the emission of CO{sub 2} (with and without changes in soil carbon), methane and nitrous oxide. The 21 mitigation measures are listed below (figures in brackets show the assumed implementation potential): 1. Biogas from livestock manure/slurry (10 % of total slurry production) 2. Biogas from slurry and maize (10 % of total slurry production) 3. Biogas from organic clover 4. Additional fat in diet for dairy cows (80% of conventional dairy cow stock and 20 % of organic dairy cow stock) 5. Additional concentrated feed in diet for other cattle (25 % of cattle stock under 2 years of age) 6. Prolonged lactation period for dairy cows (10 % of dairy cow stock) 7. Acidification of slurry (10 % of total slurry production) 8. Covers on slurry containers (40 % of total slurry production) 9. Cooling of pig slurry (10 % of pig slurry) 10. Nitrification inhibitors in nitrate fertilisers (100 % of chemical fertilisers with nitrogen) 11. Increased nitrogen utilization requirement for degassed slurry in nitrogen quota system (50 % of total slurry production) 12. Increased nitrogen

    Background Molecular analysis of neovascularization related genes by time course in response to ischemia has not been described in the context of aging. We aimed to provide a progressively deeper understanding of how aging compromises neovascularization.Methods Young (3-month) and old (18-month) C57BI mice were subjected to left hindlimb ischemia. Necrosis score was evaluated in calf muscles. Calf muscles,peripheral blood,bone marrow were harvested at different time points. The expressions of matrix metalloproteiniase-9 (MMPg),endothelial nitric oxide synthase (eNOS),vascular endothelial growth factor (VEGF),stromal derived growth factor-1 (SDF1),hypoxia inducible factor-1α (HIF1α),VEGF receptor-1(Fit1),VEGF receptor-2 (Flk1),angiopoietin-1 (Ang1),CD133,CD26 were detected by RT-PCR or Western blotting.White blood cells were counted in the peripheral blood. Gene expression data were compared by two-way analysis of variance.Results MMP9,HIF-1α and SDF-1 were more upregulated during acute ischemia in old vs. young mice,reflecting increased ischemia in aging mice. However VEGF and eNOS exhibited lower expression in old vs. young mice,despite greater ischemia intensity. Ang1 and Flk1 showed similar expression in old vs. young mice. MMP9 peaked earlier in peripheral blood in young vs. old mice. Concurrent decreasing CD26 and increasing CD133 expression in aging bonemarrow suggest aging impairs progenitor cell mobilization,Conclusions Our results indicate that a complex array of defects occur with aging that interfere with optimal neovascularization. These include potential impaired mobilization of progenitor cells to ischemic tissue,decreased levels of eNOS and VEGF and delayed responses to ischemia.ZLEr.

    Exercise training has proven to be beneficial in the prevention of disease. In addition, exercise can improve the pathogenesis and symptoms associated with a variety of chronic disease states and can attenuate drug-induced adverse effects. Exercise is a drug-free polypill. Because the benefits of exercise are clear and profound, Exercise is Medicine, a joint initiative between the American Medical Association and American College of Sports Medicine, was launched in 2007 to call on all health care providers to counsel patients and prescribe exercise in the prevention and treatment of chronic disease states. Pharmacists play an increasing role in direct patient care and are the most accessible health care providers in the community. Thus, pharmacists should be knowledgeable in counseling patients on the frequency, intensity, time, and type of exercise that is appropriate for various conditions and disease states. The aim of the present study was to determine the prevalence of didactic course offerings in United States pharmacy school curricula regarding training in exercise prescription. School websites were accessed for information regarding course offerings in PharmD programs. No United States pharmacy schools offered courses that were dedicted to the role of exercise in disease prevention or exercise prescription in disease management. Ninety percent of pharmacy schools did not offer courses with the keywords "exercise," "fitness, or "physical activity" in the title or description. The data suggest that student pharmacists are not adequately trained to counsel patients on the benefits of exercise or exercise prescription. PMID:27445279

    Corporations have long influenced environmental and occupational health in agriculture, doing a great deal of damage, making substantial profits, and shaping public debate to make it appear that environmental misfortunes are accidents of an otherwise well-functioning system, rather than systemic. The debate over the genetically modified (GM) crops is an example. The largest producer of commercial GM seeds, Monsanto, exemplifies the industry's strategies: the invocation of poor people as beneficiaries, characterization of opposition as technophobic or anti-progress, and portrayal of their products as environmentally beneficial in the absence of or despite the evidence. This strategy is endemic to contemporary market capitalism, with its incentives to companies to externalize health and environmental costs to increase profits. PMID:16350477

    Full Text Available Through this research is analyzed labor force from Romanian agriculture. The agriculture in Romania has a very large share in the Gross Domestic Product (GDP. Compared to other countries, the share of romanian agriculture in the GDP is 1.6 times higher compared to Hungary, almost three times compared to Poland and more than nine times to European Union. This does not explain the performance of romanian agriculture, but rather show the underperforming of the other sectors (industry and services sector from Romania compared to those sectors of the developed countries. Also, Romania is currently one of the European countries, with the most farmers about 30% of the total active population. This share is almost 40% of the number of farmers, existing in the European Union, where the share of the active population in agriculture of all activities, is less than 5%. In Romania, the share of active population employed in agriculture, was relatively stable until 1990, about 3 million people were employed in this area. Structural economic reforms and dismantling of Agricultural Production Cooperatives of the early 1990s led to a drastic increase of the labor force employed in agriculture area. Rural labor force is engaged mainly in the agricultural sector, which is one of the major constraints of economic development of the country. Regarding of the quantitative and qualitative structural evolution of the labor resources in romanian agriculture, on long-term, the employment in agriculture fall into the general tend of all countries wich are in the course of modernization, respectively of the absolute and relative reduction.

    A previous genome-wide association study (GWAS) of more than 100,000 individuals identified molecular-genetic predictors of educational attainment. We undertook in-depth life-course investigation of the polygenic score derived from this GWAS using the four-decade Dunedin Study (N = 918). There were five main findings. First, polygenic scores predicted adult economic outcomes even after accounting for educational attainments. Second, genes and environments were correlated: Children with higher polygenic scores were born into better-off homes. Third, children's polygenic scores predicted their adult outcomes even when analyses accounted for their social-class origins; social-mobility analysis showed that children with higher polygenic scores were more upwardly mobile than children with lower scores. Fourth, polygenic scores predicted behavior across the life course, from early acquisition of speech and reading skills through geographic mobility and mate choice and on to financial planning for retirement. Fifth, polygenic-score associations were mediated by psychological characteristics, including intelligence, self-control, and interpersonal skill. Effect sizes were small. Factors connecting DNA sequence with life outcomes may provide targets for interventions to promote population-wide positive development. PMID:27251486

    The theory of relativity has become a cornerstone of modern physics. Over the course of time it has been scrutinized in a multitude of experiments and has always been verified with high accuracy. The correctness of this theory can no longer be called into question. Right after its discovery by Albert Einstein in 1905, special relativity was only gradually accepted because it made numerous predictions contradicting common sense, fervently castigated by Einstein, and also defied experiment for too long a time. It was only with the advent of particle or high energy physics that matter could be ac

    Full Text Available Abstract Background Although rural Canadians are reported to have higher rates of diabetes than others, little is known about the relative influence of known versus agriculture-related risk factors. The purpose of this research was to carry out a comprehensive study of prevalence, risk factors and co-morbidities of diabetes among adults in rural Saskatchewan and to determine possible differences between those living on and off farms. Methods In 2010, we conducted a baseline mail-out survey (Saskatchewan Rural Health Study of 11,982 households located in the province′s four agricultural quadrants. In addition to self-reported physician-diagnosed diabetes, the questionnaire collected information from farm and small town cohorts on possible diabetes determinants including lifestyle, family history, early life factors and environmental/agricultural-related exposures. Clustering effect within households was adjusted using Generalized Estimating Equations approach.

    2010-01-01

    A doctoral program in Systems Agriculture was initiated at West Texas A&M University, Canyon, TX, in September, 2003. The stated objective of the program was "..to prepare leaders for the agricultural industry that are trained in a multidisciplinary, research-based curriculum that emphasizes a systems approach to problem solving". The program offers a single doctoral degree in Agriculture and accepts qualified students with a master's or professional degree in agricultural or related disciplines. Courses related to systems methodologies, leadership, agricultural economics, plant and soil science, and animal science are required. Additional program requirements include a systems research project and dissertation, leadership training, and written and oral exams. The program has exceeded enrollment and graduation targets, suggesting interest in this approach to a doctoral degree. Students have entered the program with M.S. backgrounds in education, traditional agricultural disciplines, veterinary medicine, business, and physics. Graduates have gained employment in industry, university teaching and research, government research/administration, and extension. Doctoral student projects in systems agriculture contributed to curriculum changes and to the conceptual framework adopted by a multi-state research group. Designing and teaching courses for students with diverse backgrounds has been challenging. Development of a common understanding of systems agriculture was identified by a third-party program review as an issue for faculty. Development and maintenance of program standards and administrative procedures posed additional challenges. Leadership, administrative support, and timely and continuing program assessment are suggested as necessary components for a nontraditional doctoral program. PMID:20491404

  16. Emergy Evaluations of Denmark and Danish Agriculture. Assessing the Limits of Agricultural Systems to Power Society

    As the process of industrialization has run its course over the twentieth century, the relative importance of agriculture as an economic activity and a means of cultural sustenance for nations has declined dramatically. In this thesis, a historical ecological-economic perspective offers insights into both the causes and effects of Danish agriculture's decline in economic importance relative to the economy of Denmark as a whole. Emergy evaluations were made of the national economy and agricultural subsystem of Denmark for the years 1936, 1970 and 1999. Emergy is defined as all the available energy that was used in the work of making a product and expressed in units of one type of energy. In total, six separate emergy analyses were performed. By quantifying the emergy requirements of both a national agricultural system and the economy within which this system is nested, the analysis highlights the changing relationship of these two systems over a temporal scale of 63 years. The ecological sustainability of the studied systems is assessed through the calculation of emergy-based indices and ratios. In accordance with emergy theory, ecological sustainability is considered to be a function of the dependence of a system on renewable emergy, the degree to which the system depends on imported emergy, and the overall load that the system places on the environment. The analysis indicates that as the national economy of Denmark evolved to rely more on the use of nonrenewable emergy and on emergy appropriated through trade to stimulate economic activity and to generate wealth, its sustainability declined, and the importance of the Danish agricultural system to the national economy subsided. While the total amount of emergy supporting the economy of Denmark over the period studied increased substantially, the total emergy supporting agriculture remained relatively constant. Furthermore, though the emergy signature and thermodynamic efficiencies of Danish agricultural

    Full Text Available Evolution of relations between agriculture and breeding was studied in peanut basin in Senegal and cotton area in northern Cameroon. Joint development of animal traction, peanut and cotton furthered the emergence of mixed systems (agriculture and breeding. The producer’s strategy of capitalization in cattle is still existing but conflicts in access to natural resources and evolution of urban markets let them to intensify breeding systems, especially in high populated areas located near cities. To make these evolutions sustainable, it’s necessary to enhance vegetal biomass production and to reduce losses of water and soil nutrients. Weaknesses of approaches based only on technology transfer have been shown. Research must get involved more actively in developing different options with farmers to manage production areas (from farm to region. At the end, a renewed framework for analysis and intervention is proposed. It combines 3 complementary approaches related to (i technical farming systems, (ii management of production units and organization of commodity chains, and (iii collective resource management.

    The evolution of policies relating to the financial burden imposed on Taiwan farmers makes a convincing case for the proposition that the capital input needed for the industrial development of a poverty-stricken region can be provided by its farming undertakings via explicit taxation and the implicit financial burdens imposed on its farmers. Following successful industrial development and economic take-off, one may shift from preferential policies to policies involving subsidies, in an effort to protect the development of agriculture and raise farmers' household incomes.

    Full Text Available Abstract Background Severe obesity is a complex condition that is associated with a wide range of serious health complications and reduced health-related quality of life (HRQoL. In addition to physiological factors, activity and participation, environmental factors, and personal factors are related to an individual’s overall quality of life HRQoL. In Norway, a course based on cognitive behavioral principles is offered to people seeking medical treatment for weight management. The aim is to assist participants to achieve a healthier lifestyle and thereby improve their HRQoL. We therefore investigated changes in HRQoL in participants after they attended this learning and mastery course, and explored how well sociodemographic variables, paid work, social support, personal factors, and surgery predicted HRQoL at 12-month follow-up. Methods A single-group longitudinal study was conducted. Data were collected by self-reported questionnaires. This article reports on those who had completed the questionnaire at the 12-month (n = 69 follow-up. HRQoL was assessed with the EQ-5D. Other standardized instruments measured employment, social support, self-efficacy, and surgery. Results At the 12-month follow-up, participants scored higher on all dimensions of the EQ-5D and on the EQ-VAS. Generalized linear model showed that having paid work, and social support were statistically significant predictors of HRQoL at the 12-month follow-up. Sex, self-efficacy, and surgery were not statistically significant associated with HRQoL. Conclusions Participation in paid work, and receiving social support from persons with whom they had a close relationship were strongly related to HRQoL in obese people 12 months after participating in a learning and mastery course. Trial registration The study is registered in Clinical Trials: NCT01336725.

  1. The relative importance of fertilization and soil erosion on C-dynamics in agricultural landscapes of NE Germany

    The hummocky ground moraine landscape of north-east Germany is characterized by distinct small-scale soil heterogeneity on the one hand, and intensive energy crop cultivation on the other. Both factors are assumed to significantly influence gaseous C exchange, and thus driving the dynamics of soil organic carbon stocks in terrestrial, agricultural ecosystems. However, it is not yet clear to which extent fertilization and soil erosional status influence soil C dynamics and whether one of these factors is more relevant than the other. We present seasonal and dynamic soil C balances of biogas maize for the growing season 2011, recorded at different sites located within the CarboZALF experimental area. The sites differ regarding soils (non-eroded Albic Luvisols (Cutanic), extremely eroded Calcaric Regosol and depositional Endogleyic Colluvic Regosol,) and applied fertilizer (100% mineral N fertilizer, 50% mineral and 50% N organic fertilizer, 100% organic N fertilizer). Fertilization treatments were established on the Albic Luvisol (Cutanic). Net-CO2-exchange (NEE) and ecosystem respiration (Reco) were measured every four weeks using a dynamic flow-through non-steady-state closed manual chamber system. Gap filling was performed based on empirical temperature and PAR dependency functions to derive daily NEE values. At the same time, daily above-ground biomass production (NPP) was estimated based on biomass samples and final harvest, using a sigmoidal growth function. In a next step, dynamic soil C balances were generated as the balance of daily NEE and NPP considering the initial C input due to N fertilizers. The resulted seasonal soil C balances varied from strong C losses at the Endogleyic Colluvic Regosol (602 g C m-2) to C gains at the Calcaric Regosol (-132 g C m-2). In general, soils exerted a stronger impact on seasonal and dynamic C balances compared to differences in applied N fertilizer. There are indications that inter-annual variations in climate conditions

    The objective of this study is the analysis of damaging frost events in agriculture, by examining the relationship between the daily minimum temperature in the lower atmosphere (at an isobaric level of 850 hPa) and crop production losses. Furthermore, the study suggests a methodological approach for estimating agriculture risk due to frost events, with the aim of estimating the short-term probability and magnitude of frost-related financial losses for different levels of 850 hPa temperature. Compared with near-surface temperature forecasts, temperature forecasts at the level of 850 hPa are less influenced by varying weather conditions or by local topographical features; thus, they constitute a more consistent indicator of the forthcoming weather conditions. The analysis of the daily monetary compensations for insured crop losses caused by weather events in Greece shows that, during the period 1999-2011, frost caused more damage to crop production than any other meteorological phenomenon. Two regions of different geographical latitudes are examined further, to account for the differences in the temperature ranges developed within their ecological environment. Using a series of linear and logistic regressions, we found that minimum temperature (at an 850 hPa level), grouped into three categories according to its magnitude, and seasonality, are significant variables when trying to explain crop damage costs, as well as to predict and quantify the likelihood and magnitude of damaging frost events.

  7. Risk factors and clinical courses of chemoradiation-related arterio-esophageal fistula in esophageal cancer patients with clinical invasion of the aorta

    International Nuclear Information System (INIS)

    Although concurrent chemoradiotherapy (CRT) is a standard treatment for esophageal cancer invading adjacent structures (T4-EC), arterio-esophageal fistula (AEF) occurs occasionally as a critical adverse event of T4-EC with CRT. The frequency, clinical course, and risk factors of AEF related to CRT are not well known. We retrospectively analyzed 48 patients with T4-EC invasion of the aorta who were treated with 5-fluorouracil, cisplatin, and concurrent radiotherapy at our institution between September 2002 and April 2009. Treatment-related AEF was defined as AEF without obvious tumor progression. We evaluated the frequency, clinical courses, and risk factors of AEF. The median survival time was 10.6 months with a median follow-up time of 33.3 months. The 2-year survival rate was 25%. Treatment-related AEF was observed in 7 patients (14.6%) and 4 of them died of massive bleeding due to aortic AEF. In the other 3 patients with non-aortic AEF, hemorrhage could be arrested by transcatheter arterial embolization (TAE). In the univariate analysis of risk factors for AEF, lower serum cholesterol level was a risk factor for AEF (odds ratio (OR) 14.7; 95% confidence interval (CI) 1.58-137; P=0.008). Although CRT has a curative potential even for patients with T4-EC invading the aorta, we should be aware of the relatively high incidence of treatment-related AEF. TAE may be successful in rescuing a non-aortic AEF patient. Low serum cholesterol level may be a risk factor for AEF, but further investigation is needed. (author)

    In the last 25 years, the number and scope of fish-related journals have changed. New and existing journals are increasingly specialized. Journals that are read and cited are changing because of differential accessibility via electronic databases. In this review, we examine shifts in numbers and foci of existing fish-related journals. We ask how these fish-related metrics differ across type of application, ecological system, taxa, and discipline. Although many journals overlap to some extent in content, there are distinct groups of journals for authors to consider. By systematically reviewing the focus of an individual manuscript, comparing it to the suite of journals available and examining the audience for the manuscript, we believe that authors can make informed decisions about which journals are most suitable for their work. Our goal here is to help authors find relevant journals and deliver scientific publications to the appropriate readership.

    The diet, its quality and quantity considerably influence population parameters of rodents. In this study, we used NIRS methods for estimation of nitrogen content in stomachs of rodent populations. The study was carried out in diverse arable landscape in South Moravia, Czech Republic. Rodents were sampled in cultural crops (alfalfa, barley, wheat, sunflower, maize and rape) as well as in fallow habitats (herbal set-aside and old orchard). Influence of habitat, date, year, individual parameters (body length, sex, breeding and age), and relative abundance on quality of consumed food was studied. Under conditions of higher population density, dominant species [wood mouse (Apodemus sylvaticus) and common vole (Microtus arvalis)] consumed food richer in nitrogen. Also the strong effect of crop and date (season) was found in both species. There was no significant effect of the other parameters studied on food quality (N-content). PMID:27099997

    2015-07-01

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

    For assessment of the dose-response relationship between concentrations of microbial agents in the air of various agricultural settings and occurrence of work-related symptoms in exposed workers, a meta-analysis of the results obtained in 1994-2007 on the territory of eastern Poland was performed. The studies on the airborne concentrations of total culturable microorganisms, mesophilic bacteria, Gram-negative bacteria, thermophilic actinomycetes, fungi, and bacterial endotoxins, as well as on the frequency of work-related respiratory and general symptoms in the exposed workers, were carried out at grain, thyme, valerian, flax, and hop handling on farms, in cow barns, piggeries, horse stables and in a modern hatchery. The airborne concentrations of the total microorganisms were in the range of 9.2-1236.5 × 10(3) CFU/m(3) , of the total mesophilic bacteria 3.5-1225.8 × 10(3) CFU/m(3) , of Gram-negative bacteria 0.0- 46.2 × 10(3) CFU/m(3) , of thermophilic actinomycetes 0.0-7.1 × 10(3) CFU/m(3) , of fungi 2.1-77.9 × 10(3) CFU/m(3) , and of bacterial endotoxin 0.00925-429.55 µg/m(3) . The frequency of work-related symptoms ranged between 21.7-63.8%. In a meta-analysis for assessment of the correlations between the log-transformed concentrations of airborne microbial agents and the occurrence of work-related symptoms, the multiple regression test was applied. Statistically significant correlations were found between the occurrence of work-related symptoms and the concentration of total airborne microorganisms (R=0.748555; P=0.020317), mesophilic bacteria (R=0.7573; P=0.029548), Gram-negative bacteria (R=0.835938; P=0.019129), and endotoxins (R=0.705356; P=0.03378). The correlations between the concentrations of thermophilic actinomycetes and fungi, on one side, and frequency of work-related symptoms on the other, did not attain the threshold of significance (P=0.087049 and P=0.062963, respectively).

  19. The course of health-related quality of life in head and neck cancer patients treated with chemoradiation: A prospective cohort study

    International Nuclear Information System (INIS)

    Background and purpose: To evaluate the course of health-related quality of life (HRQOL) from diagnosis to 2 years follow-up in patients with head and neck cancer (HNSCC) treated with chemoradiation (CRT). Materials and methods: 164 patients completed the EORTC QLQ-C30 and QLQ-H and N35 questionnaires 1 week before and 6 weeks and 6, 12, 18, and 24 months after CRT. Patients were compared to a reference group. A linear mixed-model analysis was used to assess changes in HRQOL over time, and whether this was associated with age, gender, comorbidity, and tumor sublocation. Results: Significant differences for the majority of HRQOL scales were observed between patient and reference group at baseline, and follow-up. The course of HRQOL was different for survivors compared to non-survivors. In survivors, improvement over time was observed (in global quality of life, physical, role, and social function, fatigue, pain, swallowing, speech, social eating, and social contacts), while in non-survivors the pattern over time was either no changes in HRQOL or a deterioration (in physical function, social eating and contacts). In both survivors and non-survivors, emotional functioning improved after treatment, but deteriorated in the longer term. Patients with comorbidity reported worse physical function, and patients with oral/oropharyngeal cancer (compared to hypopharyngeal/laryngeal cancer) reported more oral pain and sexual problems, but fewer speech problems. Conclusions: The course of HRQOL of HNSCC patients during the first 2 years after CRT is different for survivors compared to non-survivors and is associated with comorbidity and tumor subsite

  20. MODERNIZATION OF AGRICULTURE VS SUSTAINABLE AGRICULTURE

    Directory of Open Access Journals (Sweden)

    2014-04-01

    Full Text Available The paper shows the correlation between the need to modernise agriculture and sustainable development. Modernisation of agriculture aiming only at increasing the efficiency of production, if implemented in accordance with the principles of sustainable development, enabled reduction in the negative external effects. Modernisation of agriculture is supposed to ensure productivity growth without imposing any threats to the natural environment and the well-being of animals, reduced impoverishment in rural areas as well as to ensure food security, growth in the profitability of farms, improvement to the efficiency of use of natural resources. Therefore, in the near future, the agriculture – environment relation will be subject to change taking into account, on the one hand, concern about the natural environment, and, on the other, pressure on increasing the efficiency of production. The above challenges will be addressed by the need to implement efficient and, at the same time, environmentally-friendly production technologies and relevant legal instruments which oblige agricultural producers to protect the natural environment.

  3. Nature-Based Stress Management Course for Individuals at Risk of Adverse Health Effects from Work-Related Stress—Effects on Stress Related Symptoms, Workability and Sick Leave

    Directory of Open Access Journals (Sweden)

    2014-06-01

    Full Text Available Sick leave due to stress-related disorders is increasing in Sweden after a period of decrease. To avoid that individuals living under heavy stress develop more severe stress-related disorders, different stress management interventions are offered. Self-assessed health, burnout-scores and well-being are commonly used as outcome measures. Few studies have used sick-leave to compare effects of stress interventions. A new approach is to use nature and garden in a multimodal stress management context. This study aimed to explore effects on burnout, work ability, stress-related health symptoms, and sick leave for 33 women participating in a 12-weeks nature based stress management course and to investigate how the nature/garden activities were experienced. A mixed method approach was used. Measures were taken at course start and three follow-ups. Results showed decreased burnout-scores and long-term sick leaves, and increased work ability; furthermore less stress-related symptoms were reported. Tools and strategies to better handle stress were achieved and were widely at use at all follow-ups. The garden and nature content played an important role for stress relief and for tools and strategies to develop. The results from this study points to beneficial effects of using garden activities and natural environments in a stress management intervention.

  5. The Effect of the Common Agricultural Policy Reform by 2013 on Direct Payments in Relation to Animal Welfare in the European Union - Review

    Directory of Open Access Journals (Sweden)

    Marek Angelovič

    2011-10-01

    Full Text Available The primary role of agriculture is to provide food and the European Union should be able to contribute to rising world food demand. The Common Agriculture Policy covers the wide variety of measures used to support and protect the European Union farmers. The most important measure within the Common Agriculture Policy is direct payments paid directly to farmers to protect their income. The Common Agriculture Policy is due to be reformed by 2013. The main object of the Common Agriculture Policy, which is a provision of safe, healthy choice of food at transparent and affordable prices, will remain unchanged, but further changes of the Common Agriculture Policy are necessary to respond to the new challenges such as animal welfare, global food security, natural resources such as water, air, biodiversity and soil, climate changes, increasing globalization and rising price volatility.

    Head, Denise; Raz, Naftali; Gunning-Dixon, Faith; Williamson, Adrienne; Acker, James D

    2002-03-01

    This study examined the impact of age-related differences in regional cerebral volumes and cognitive resources on acquisition of a cognitive skill. Volumes of brain regions were measured on magnetic resonance images of healthy adults (aged 22-80). At the early stage of learning to solve the Tower of Hanoi puzzle, speed and efficiency were associated with age, prefrontal cortex volume, and working memory. A similar pattern of brain-behavior associations was observed with perseveration measured on the Wisconsin Card Sorting Test. None of the examined structural brain variables were important at the later stages of skill acquisition. When hypertensive participants were excluded, the effect of prefrontal shrinkage on executive aspects of performance was no longer significant, but the effect of working memory remained.

    Full Text Available Context Data from Asian populations about gender-related differences in Crohn’s disease are few. Objectives This study was to analyze the clinical characteristics between women and men affected by Crohn’s disease. Methods This was a retrospective cohort study to analyze consecutive Crohn’s disease patients from Jan 2000 to Dec 2012. Clinical and phenotypic characteristics and treatment outcomes were evaluated. Results 79 patients (55 male and two of them with positive family history were diagnosed with Crohn’s disease. Ileocolonic disease and inflammatory lesion was the most dominant site of involvement and disease behavior respectively in both men and women. Apart from higher frequency of nausea (45.83 vs 23.64%, P 0.024 and lower body mass index (19.44 vs 22.03 kg/m2, P 0.003 reported in women, no significant gender-related differences in clinical characteristics were observed. Women were more associated with delay use of immunosuppressive therapy (12 vs 36 months, P = 0.028, particularly for those aged less than 40 years old (85 vs 62.6%, P = 0.023. Cox proportional hazard regression analysis revealed that active smoking (HR, 4.679; 95% CI, 1.03-21.18 and delayed use of immunosuppressive therapy (HR, 4.13; 95% CI, 1.01-16.88 were only independent risk factors associated with increased risk of complications. Conclusions There were no significant gender-specific differences in clinical and phenotypic characteristics between male and female Crohn’s disease patients. Smoking history and delay use of immunosuppressive therapy were associated with higher risk of complications.

    Objective To discuss the relation between the course of type 2 diabetes (2 DM) and blood sugar, body mass index (BMI), insulin resistance (INS), and the secretion function of insulin, and the effects of these factors to the quality of life. Methods The 233 patients were divided into 5 groups. They were normal sugar tolerance (A) group, impaired sugar tolerance (B) group, the course of DM less than 5 years(C) group, the course of DM between 5~ 9 years(D) group, and the course of DM more than 10 years (E)group. To measure the blood sugar, BMI, the area under the INS Curve, INS active index (IAI), INS secretion index (IS) were calculated to analyze their effects in the course of type 2 DM. Results From group A to group E, FPG, 1 hour PG, 2 hour PG, and the area of blood sugar were much higher with the course of DM, and increased progressively. IAI was much lower with the course of DM, and descended progressively.Conclusion In the course of 2 DM, the level of blood sugar rose progressively and the progressive impairment of INS and the secretion function of insulin had important effects in this term.

  16. Evolution of exchangeable copper and relative exchangeable copper through the course of Wilson's disease in the Long Evans Cinnamon rat.

    Directory of Open Access Journals (Sweden)

    Françoise Schmitt

    Full Text Available BACKGROUND: Wilson's disease (WD is an inherited disorder of copper metabolism leading to liver failure and/or neurological impairment. Its diagnosis often remains difficult even with genetic testing. Relative exchangeable copper (REC has recently been described as a reliable serum diagnostic marker for WD. METHODOLOGY/PRINCIPAL FINDINGS: The aim of this study was to validate the use of REC in the Long Evans Cinnamon (LEC rat, an animal model for WD, and to study its relevance under different conditions in comparison with conventional markers. Two groups of LEC rats and one group of Long-Evans (LE rats were clinically and biologically monitored from 6 to 28 weeks of age. One group of LEC rats was given copper-free food. The other groups had normal food. Blood samples were collected each month and different serum markers for WD (namely ceruloplasmin oxidase activity, exchangeable copper (CuEXC, total serum copper and REC and acute liver failure (serum transaminases and bilirubinemia were tested. Every LEC rat under normal food developed acute liver failure (ALF, with 40% global mortality. Serum transaminases and bilirubinemia along with total serum copper and exchangeable copper levels increased with the onset of acute liver failure. A correlation was observed between CuEXC values and the severity of ALF. Cut-off values were different between young and adult rats and evolved because of age and/or liver failure. Only REC, with values >19%, was able to discriminate LEC groups from the LE control group at every time point in the study. REC sensitivity and specificity reached 100% in adults rats. CONCLUSIONS/SIGNIFICANCE: REC appears to be independent of demographic or clinical data in LEC rats. It is a very simple and reliable blood test for the diagnosis of copper toxicosis owing to a lack of ATP7B function. CuEXC can be used as an accurate biomarker of copper overload.

  19. Interregional training course on use of nuclear and related techniques to measure storage, flows and balance of water in cropping systems

    International Nuclear Information System (INIS)

    An interregional training course on the Use of Nuclear and Related Techniques to Measure Storage, Flows and Balance of Water in Cropping Systems was organized jointly by the SWMCN Section and the Soil Science Unit (SSU) and held from 1 to 25 October 2007 at the Agency's Laboratories, Seibersdorf. In the first week of the Course participants learned about new developments in soil water monitoring devices and took part in computer laboratory exercises aimed at estimating crop water use. The participants were taught the principles behind the electromagnetic (capacitance) probes and why they do not work effectively. During practical sessions they learned how to use the hydroprobes in the field and also learned how to build their own time domain reflectometry (TDRs). It was emphasized that the soil moisture readings from the neutron probe are currently the best, but the need for better capacitance sensors was advocated. Lectures and practicals during the second week focused on plant water relationships, evapotranspiration and crop water use and requirements. Participants learned about the theory and construction of thermocouples and TDR sap flow sensors and constructed their own thermocouples and TDR sap flow sensors to measure and analyze sap flow in citrus. The use of porometers to measure transpiration and leaf conductance and portable infra red (IR) thermometers for measuring the crop water stress index was also demonstrated. As a follow up to the lectures in the second week, the third week lectures and practical sessions in the third week focused on an introductory lecture which outlined the use of stable isotopes to trace plant source water, leaf water isotope enrichment and transpiration and combining 13C and 18O to understand plant response to a water deficit. Participants had field practicals on isotopic procedures for determining sources and fluxes of water in plants and soil, and isotopic methods for integrating inputs and losses to receiving water bodies

  20. Health-Related Quality of Life in Elderly Patients With Newly Diagnosed Glioblastoma Treated With Short-Course Radiation Therapy Plus Concomitant and Adjuvant Temozolomide

    International Nuclear Information System (INIS)

    Purpose: To describe the quality of life (QOL) in elderly patients with glioblastoma (GBM) treated with an abbreviated course of radiation therapy (RT; 40 Gy in 15 fractions) plus concomitant and adjuvant temozolomide (TMZ). Methods and Materials: Health-related QOL (HRQOL) was assessed by European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core-30 (QLQ-C30, version 3) and EORTC Quality of Life Questionnaire Brain Cancer Module (QLQ-BN20). Changes from baseline in the score of 9 preselected domains (global QLQ, social functioning, cognitive functioning, emotional functioning, physical functioning, motor dysfunction, communication deficit, fatigue, insomnia) were determined 4 weeks after RT and thereafter every 8 weeks during the treatment until disease progression. The proportion of patients with improved HRQOL scores, defined as a change of 10 points or more, and duration of changes were recorded. Results: Sixty-five patients completed the questionnaires at baseline. The treatment was consistently associated with improvement or stability in most of the preselected HRQOL domains. Global health improved over time; mean score differed by 9.6 points between baseline and 6-month follow-up (P=.03). For social functioning and cognitive functioning, mean scores improved over time, with a maximum difference of 10.4 points and 9.5 points between baseline and 6-month follow-up (P=.01 and P=.02), respectively. By contrast, fatigue worsened over time, with a difference in mean score of 5.6 points between baseline and 4-month follow-up (P=.02). Conclusions: A short course of RT in combination with TMZ in elderly patients with GBM was associated with survival benefit without a negative effect on HRQOL until the time of disease progression

    A total of 53 high-ability students who had completed the eleventh year in high school enrolled in a standard college chemistry course at the University of Iowa. Half of them had completed a high-school course in chemistry and half had not. After 2 months of instruction during a summer session, there was no difference between groups as to attitude toward chemistry, performance on the ACS-NSTA Chemistry Achievement Examination, final examination for the course, and course grade. There was a great difference in the amount of time required of tutors; the students who had not completed high-school chemistry spent more time in studying and with tutors.

    This study aimed to evaluate the relationships between oxidative stress and heavy metal exposure (lead [Pb] and cadmium [Cd]), as well as co-factors such as physical activity and age, in Japanese women. This study was conducted with female subjects from a rural agricultural community in Japan. Subjects were asked to complete lifestyle-related questionnaires and undergo a group health examination. Physical activity, alcohol consumption, body mass index, and other demographic information were collected. Blood and urine samples were collected to measure urinary 8-hydroxydeoxyguanosine (8-OHdG) levels and blood and urinary Cd and Pb concentrations. Urine samples were analyzed using high performance liquid chromatography and flameless atomic absorption spectrometry; blood samples were analyzed using inductively coupled plasma-mass spectrometry. Age, physical activity, and blood and urinary Cd and Pb concentrations were included in structural equation modeling analysis. Two latent factors for heavy metal exposure and physical activity were produced to predict the total influence of the variables. The final model was good: CMIN/DF = 0.775, CFI = 1.000, GFI = 0.975, AGFI = 0.954, RMSEA = 0.000. 8-OHdG levels were positively associated with heavy metal exposure, physical activity, and age (standard β of path analysis: 0.33, 0.38, and 0.20, respectively). Therefore, oxidative stress is associated with both, environmental and lifestyle factors, in combination with aging. PMID:27386333

    Using the event-related potential (ERP) approach, we tracked the time-course of white participants’ empathic reactions to white (own-race) and black (other-race) faces displayed in a painful condition (i.e. with a needle penetrating the skin) and in a nonpainful condition (i.e. with Q-tip touching the skin). In a 280–340 ms time-window, neural responses to the pain of own-race individuals under needle penetration conditions were amplified relative to neural responses to the pain of other-race individuals displayed under analogous conditions. This ERP reaction to pain, whose source was localized in the inferior frontal gyrus, correlated with the empathic concern ratings of the Interpersonal Reactivity Index questionnaire. In a 400–750 ms time-window, the difference between neural reactions to the pain of own-race individuals, localized in the middle frontal gyrus and other-race individuals, localized in the temporoparietal junction was reduced to nil. These findings support a functional, neural and temporal distinction between two sequential processing stages underlying empathy, namely, a race-biased stage of pain sharing/mirroring followed by a race-unbiased stage of cognitive evaluation of pain.

    Full text: Seventeen students from Cambodia, the Republic of China, India, Israel, Pakistan, the Philippines, Syria, Thailand and the United Arab Republic attended an inter-regional training course on the use of radioisotopes in soil and plant investigations in Manila, Philippines. Held from 3 October to 25 November 1966, the course was organised by the International Atomic Energy Agency (IAEA) and the Food and Agricultural Organization (FAO) under the UN Expanded Programme of Technical Assistance. During the first three weeks, the students, most of whom had graduate training or experience in agricultural research, were taught the basic characteristics of isotopes and the techniques of measuring radiation. Lectures and practical laboratory exercises in the more specialized studies of soil-plant relations took up the rest of the time. Some of the topics covered were: field and water culture experiments, measurement of nutrient in the soil, autoradiography of plant materials, plant mutation and breeding, use of radioisotopes in the study of photosynthesis and plant growth, nuclear techniques for determining soil moisture and density, the use of labelled fertilizer in studying the efficient utilization of fertilizer, etc. Dr. Getulio B. Viado, Head of the Training Institute, Philippine Atomic Energy Commission, was Director of the course, while Dr. Shaukat Ahmed, Director of the Atomic Research Centre, West Pakistan, served as Technical Adviser and as a principal lecturer. The teaching staff consisted of Philippine scientists and three visiting professors: Dr. Victor Middelboe of the IAEA Seibersdorf Laboratory, Dr. M.S. Chandraratna of Ceylon and Dr. S.C.

    Full Text Available The study compared the support and rewards provided faculty members for online course teaching and the development approaches used at business schools accredited by AACSB between 2001 and 2006. Data were collected from 81 professors in 2001 and 140 professors in 2006. The professors were involved in developing or teaching online courses at AACSB business schools across the United States. The findings indicate that faculty members received limited support and are not taking advantage of training options. Faculty members are most likely rewarded for their involvement in distance learning through stipends based on the number of online sections taught. Little has changed during the five-year period in regards to course development. Faculty members continue to use an individual instead of a team approach to course development and most faculty members learned online course development and delivery techniques on their own.

    2013-02-01

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

  12. Regulatory and bio-safety issues in relation to transgenic animals in food and agriculture, feeds containing GMO and veterinary biologics

    International Nuclear Information System (INIS)

    The development of an effective regulatory system for genetically engineered animals and their products has been a subject of increasing discussions among researchers, industry and policy developers, as well as the public. Transgenic technology alters an animal's genome to achieve desired production or health effects of commercial or societal value. Since transgenesis itself is a relatively new scientific approach, transgenic animals are new organisms for which there is no existing information relevant to their performance under domestication or to their behavior in the wild, nor is there any firm basis for predicting their potential. The issues associated with the regulation and biosafety of transgenic animals pertain to environmental impact, human food safety, animal health and welfare, trade, and ethics. Many concerns related to genetic modifications in animals or plants focus on safety of the human food chain. Given the present public perception of animal biotechnology in general, transgenic animals are viewed with varying degrees of optimism and skepticism. In light of these divergent views the question that remains to be answered is how to develop regulations that safeguard the public concerns and at the same time allow this technology to benefit agriculture, in a manner that neither 'restricts' nor 'facilitates'. Transgenic animals are produced for four basic reasons: to improve animal health, to increase productivity and improve product quality, to mitigate the environmental impact of foodanimal production, and to produce therapeutics. To date, scientists have been able to add, delete, silence or partially activate genes of interest. To regulate such a powerful technology predicated on limited background information is a challenge not only to the regulators, but also to the developers who strive to prove that these animals are safe by demonstrating bioequivalency to their conventional counterparts. The regulations are based on the principle of substantial

    Full Text Available This study investigates the determinants of agricultural output in Syria, 1980-2010. The Johansen cointegration test results indicate that agricultural outputs are positively related to the capital, food exports, expenditure and arable land, and negatively related to the oil price. Arable land has the biggest effect on agricultural outputs. The Granger causality test indicates bidirectional short-run causality relationships between capital, food exports, expenditure, arable land and agricultural outputs, and unidirectional short-run causality relationship running from oil price to agricultural outputs. There are also unidirectional long-run causality relationships moving from agricultural outputs to gross fixed capital formation of agriculture, oil price, food exports and arable land. However, there is no long-run causality relationships between final consumption expenditure and agricultural outputs. The result indicates that it is important to speed up the land reclamation process and encourage the investment in the agricultural sector.

    Full Text Available Relationship between evolution in the agriculture and in the water quality from 1950 to 2000. In 1991, Europe has adopted the Nitrates Directive to reduce the impact of agriculture on water nitrate pollution. Nitrate concentration in groundwater has not always been so worrying as it was at the end of the ’80. Working on the revision of Action Programme, it is usefull to list changes in agriculture during the two decades before the degradation of water quality. So, with regards to land use, we observe a huge decrease of grassland cover and an increase of maize surfaces. Livestock has highly increased during this period. Finally, use of nitrogen (mineral and organic has increased out of proportion to the yield increase. Following this analyze, loss of grassland cover should be at least stopped, nitrogen supplies should strictly correspond to crop needs, taking into account the soil restitutions.

    In the Central Negev hills (Israel) many ancient terraced wadis exist, which captured run-off and caused gradual soil aggradation, which enabled agricultural practices. In these terraces, dark colored soil horizons were observed, containing charcoal, as can be found in Terra Preta soils, suggesting

  6. Regulatory and biosafety issues in relation to transgenic animals in food and agriculture, feeds containing genetically modified organisms (GMO) and veterinary biologics

    International Nuclear Information System (INIS)

    Development of an effective regulatory system for genetically engineered animals and their products has been the subject of increasing discussion among researchers, industry and policy developers, as well as the public. Since transgenesis and cloning are relatively new scientific techniques, transgenic animals are new organisms for which there is limited information. The issues associated with the regulation and biosafety of transgenic animals pertain to environmental impact, human food safety, animal health and welfare, trade and ethics. To regulate this new and powerful technology predicated on limited background information is a challenge not only for the regulators, but also for the developers of such animals, who strive to prove that the animals are safe and merit bio-equivalency to their conventional counterparts. In principle, an effective regulatory sieve should permit safe products while forming a formidable barrier for those assessed of posing an unacceptable risk. Adoption of transgenic technology for use in agriculture will depend upon various factors that range from perceived benefits for humans and animals, to safe propagation, animal welfare considerations and integrity of species, as well as effects on bio-diversity. A regulatory framework designed to address the concerns connected with the environmental release of transgenic animals needs to also take into account the ability of genetically modified animals to survive and compete with conventional populations. Regulatory initiatives for biotechnology-derived animals and their products should ensure high standards for human and animal health; a sound scientific basis for evaluation; transparency and public involvement; and maintenance of genetic diversity. Feeds obtained by use of biotechnology have to be evaluated for animal and human safety by using parameters that define their molecular characterization, nutritional qualities and toxicological aspects, while veterinary biologics derived from

  9. Natural resources in the Agriculture

    International Nuclear Information System (INIS)

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

    Directory of Open Access Journals (Sweden)

    2015-04-01

    Full Text Available Agricultural production risk is of special nature due to a great number of hazards, relative weakness of production entities on the market and high ambiguity which is greater than in industrial production. Natural disasters occurring very frequently, at simultaneous low percentage of insured farmers, cause damage of such sizes that force the state to organise current financial aid (for instance in the form of preferential natural disaster loans. This aid is usually not sufficient. On the other hand, regional diversity of the risk level does not positively affect the development of insurance. From the perspective of insurance companies and policymakers it becomes highly important to investigate the spatial structure of losses in agriculture caused by natural disasters. The purpose of the research is to classify the 16 Polish voivodeships into clusters in order to show differences between them according to the criterion of level of damage in agricultural farms caused by natural disasters. On the basis of the cluster analysis it was demonstrated that 11 voivodeships form quite a homogeneous group in terms of size of damage in agriculture (the value of damage in cultivations and the acreage of destroyed cultivations are two most important factors determining affiliation to the cluster, however, the profile of loss occurring in other five voivodeships has a very individual course and requires separate handling in the actuarial sense. It was also proved that high value of losses in agriculture in the absolute sense in given voivodeships do not have to mean high vulnerability of agricultural farms from these voivodeships to natural risks.

  18. Water Depletion Threatens Agriculture

    Science.gov (United States)

    Brauman, K. A.; Richter, B. D.; Postel, S.; Floerke, M.; Malsy, M.

    2014-12-01

    Irrigated agriculture is the human activity that has by far the largest impact on water, constituting 85% of global water consumption and 67% of global water withdrawals. Much of this water use occurs in places where water depletion, the ratio of water consumption to water availability, exceeds 75% for at least one month of the year. Although only 17% of global watershed area experiences depletion at this level or more, nearly 30% of total cropland and 60% of irrigated cropland are found in these depleted watersheds. Staple crops are particularly at risk, with 75% of global irrigated wheat production and 65% of irrigated maize production found in watersheds that are at least seasonally depleted. Of importance to textile production, 75% of cotton production occurs in the same watersheds. For crop production in depleted watersheds, we find that one half to two-thirds of production occurs in watersheds that have not just seasonal but annual water shortages, suggesting that re-distributing water supply over the course of the year cannot be an effective solution to shortage. We explore the degree to which irrigated production in depleted watersheds reflects limitations in supply, a byproduct of the need for irrigation in perennially or seasonally dry landscapes, and identify heavy irrigation consumption that leads to watershed depletion in more humid climates. For watersheds that are not depleted, we evaluate the potential impact of an increase in irrigated production. Finally, we evaluate the benefits of irrigated agriculture in depleted and non-depleted watersheds, quantifying the fraction of irrigated production going to food production, animal feed, and biofuels.

During last 20 years the increasing population andlivestock, over-reclamation, over-pasturing, over-deforesting, andother intensified negative human activities in the zone resulted incoarsening of surface soil, decrease of organic mater content insoil, reduction of vegetation coverage, variation and degradationof flora structure, and hence in desertization of the land,although average of gales and sandstorms some decreased and theclimate tended to be better in the region. However, the frequentsandstorms occurring in the springs of last and present years hasattracted much attention.

    This article starts with a profile of African agricultural trade. Using the pre-release version 9.2 of the GTAP database, we then show that the results for tariff elimination on intra-African trade are promising, but these tariff barriers are not as significant as the various trade-related barriers...... elimination, non-tariff barrier reductions and time in transit cost reductions are likely to be cumulative and would generate very large gains to Africa. The policy implications are clear: while cooperation will enhance the gains, much of the benefits will result from unilateral actions and regional...

    2013-01-01

    Through the vertical and horizontal analysis of agricultural export data in Liaoning Province during the period 2006-2010,we can find that Liaoning Province has already a major exporter of agricultural products,but there is no significant increase in many indicators with great fluctuation or declining trend. Meanwhile,compared with other provinces,the competitive advantages of agricultural export in Liaoning Province are not obvious,lacking competitive potential. Analysis shows that it is a strenuous task for Liaoning Province to transform from a major exporter of agricultural products to strong export province; during the course,relying on independent innovation is the fundamental guarantee. Liaoning Province should rely on independent innovation,to create new agricultural varieties,lead the international standards of agricultural products,form the brand agriculture,and improve the agricultural industry chain.

Or should we first try to access the literal meaning and only after failing try to find a metaphorical one in metaphor comprehension? Researchers proposed two hypotheses:the three-stage model and the parallel hypotheses.The present paper experimentally verified the above assumption.We used Event-Related Potentials(ERPs) to study the process of metaphor comprehension and focused on the time-course difference between the comprehension of metaphorical meanings and literal ones.Thirty-one participants were college students.They were asked to perform a semantic judgment task that required them to decide whether the sentence they saw on the computer screen conveyed a meaningful expression or not.The stimuli sentences were familiar metaphors,novel metaphors,literal sentences and error sentences.Each type had 50 ones:thus there were 200 stimuli sentences in all.The E-prime software was used to compile the experimental program.ERPs data revealed that the waveforms and scalp distributions of ERPs,which were evoked by literal sentences and metaphoric ones,were in agreement(see Figure 1 and Figure 2).Two dependent variables,peak amplitude value of N200 and N400s,were entered into the two-way repeated measure analysis of variance(ANOVA),with the following repeated factors;sentence types(familiar metaphors,novel metaphors

  11. Food, soil, and agriculture

    International Nuclear Information System (INIS)

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

    Central Europe, the focus region of this study, is a region in transition, climatically from maritime to continental and politically from formerly more planning-oriented to more market-oriented management regimes, and in terms of climate change from regions of increasing precipitation in the west and north of Europe to regions of decreasing precipitation in central and southern Europe. The Elbe basin, a trans-boundary catchment flowing from the Czech Republic through Germany into the North Sea, was selected to investigate the possible impacts of global change on crop yields and water resources in this region. For technical reasons, the paper has been split into two parts, the first showing the overall model concept, the model set-up for the agricultural sector, and first results linking eco-hydrological and agro-economic tools for the German part of the basin. The second part describes the model set-up for simulating water supply and demand linking eco-hydrological and water management tools for the entire basin including the Czech part.

    Traditional large lecture classes are fundamentally passive and teacher-centered. Most existing online courses are as well, including massive open online courses (MOOCs). Research tells us that this mode of instruction is not ideal for student learning. However, the unique attributes of the online environment have thus far been mostly underutilized. We hypothesize that new tools and the innovative curricula they enable can foster greater student engagement and enhance learning at large scale. To test this hypothesis, over the past three years, Arizona State University developed and offered "Habitable Worlds", an online-only astrobiology lab course. The course curriculum is based on the Drake Equation, which integrates across disciplines. The course pedagogy is organized around a term-long, individualized, game-inspired project in which each student must find and characterize rare habitable planets in a randomized field of hundreds of stars using concepts learned in the course. The curriculum allows us to meaningfully integrate concepts from Earth, physical, life, and social sciences in order to address questions related to the possibility of extraterrestrial life. The pedagogy motivates students to master concepts, which are taught through interactive and adaptive inquiry-driven tutorials, featuring focused feedback and alternative pathways that adjust to student abilities, built using an intelligent tutoring system (Smart Sparrow's Adaptive eLearning Platform - AeLP). Through the combination of the project and tutorials, students construct knowledge from experience, modeling the authentic practice of science. Because the tutorials are self-grading, the teaching staff is free to dedicate time to more intense learner-teacher interactions (such as tutoring weaker students or guiding advanced students towards broader applications of the concepts), using platforms like Piazza and Adobe Connect. The AeLP and Piazza provide robust data and analysis tools that allow us to

  18. Agriculture and the greenhouse gas emissions: A literature review

    International Nuclear Information System (INIS)

    Agriculture contributes to the greenhouse effect by increasing carbon dioxide, nitrous oxide and methane emissions. This literature review examines agricultural sources and sinks of greenhouse gases as well as factors affecting emissions. Options for mitigating emissions are presented as well the results of greenhouse gas emission measurements on Finnish agricultural soils. In addition, some basic information is given about Finnish agriculture, and the estimation of emissions using the IPCC Guidelines is described. Carbon dioxide sources include decomposition of soil organic matter, combustion and liming. The agricultural sector can mitigate CO2 emissions by increasing carbon stocks in soils and vegetation, reducing fossil fuel consumption, and increasing the production of bioenergy. There is little opportunity to decrease the amount of liming in Finland. The main nitrous oxide sources are nitrification and denitrification. N2O emissions can be reduced by enhancing plants' ability to compete for soil nitrogen and by keeping the rate of emission processes as low and the duration of emissions as short as possible. Special attention should be paid to manure management because manure contains abundant nitrogen that can be lost as N2O. Improvements in the protein feeding of livestock could also reduce potential N2O emissions from manure. Methane is emitted, for example, in the course of enteric fermentation and the anaerobic decomposition of organic matter in manure. The emission of CH4 from soils depends on the relative amounts of methane production and consumption. Cattle with high productivity emit less methane per unit of milk or meat than do animals with low productivity. The number of breeding animals could be reduced by improving animal reproduction efficiency. Methane emitted from manure should be utilized as an energy source, or the formation of it should be prevented by keeping manure under aerobic conditions

  20. Water, agriculture, energy: a growing interweaving. Towards an extended water security

    International Nuclear Information System (INIS)

    In this paper, the author first notices that the definition of water security according to the United Nations Development Program (UNDP) is a rather restrictive one. Thus, the search for a global security takes all forms of insufficiencies and (military or not) instabilities into account, and is then related to strategic stakes of State stability such as agriculture production, water or energy. He discusses the determining factors and vulnerabilities of a renewed water security and its implications. He highlights how internal political and social constraints are sources of local and regional tensions. In this respect, agriculture is at the heart of use conflicts (difficult and necessary reform of the sector, rivalries between rural and urban users), and water stress directly affects daily domestic uses. The author then outlines the necessary integration stakes related to water, food and energy by discussing the use of water in energy production, the use of energy to produce drinkable water, the relationship between agriculture and energy, and, of course between agriculture and water as agriculture is the main water consumer

    2012-04-01

    Soil has recently been attracting some renewed public attention due to its inextricable link to current environmental challenges such as climate change, food security and water resource protection. It is increasingly acknowledged that the world's future will require a better understanding of soil science. Yet enrolment in soil related programs at universities in North America and around the world has been declining. One of the proposed causes for this drop is the tendency for soil science education to emphasize the agricultural side of soil science, while our increasingly urban and environmentally conscious student population is more interested in environmental sciences. To address this issue, in 2011 we created an on-line, first-year soil science course designed specifically to communicate the significance of soil science to global environmental questions. We propose that this type of course is an effective way to help increase interest in higher level soil courses and reverse the downward trend in enrolments. The course content was centered on prominent environmental issues, which were used to introduce basic concepts of soil science. Course materials emphasized integration with other natural resources disciplines such as ecology, biogeochemistry and hydrology. The online format allowed for a seamless integration of multimedia components and web content into course materials, and is believed to be appealing to technologically savvy new generations of students. Online discussion boards were extensively used to maintain strong student engagement in the course. Discussion topics were based on soil-related news stories that helped demonstrate the relevance of soils to society and illustrate the complex and often controversial nature of environmental issues. Students also made significant use of an online bulletin board to post information about environmental events and share news stories related to the course. This course was offered for the first time in term 1 of

    2014-10-01

    Full Text Available The purpose of this descriptive study was to assess preservice agriculture teachers’ perceptions of the importance of Supervised Agricultural Experience (SAE and their views on barriers to conducting SAE. A census of the sophomore-level agricultural education course at Oklahoma State University was conducted to measure perceptions at the beginning and end of the course. This study was framed upon Ajzen’s Theory of Planned Behavior. Results indicated that preservice teachers perceived SAE was an important component of agricultural education and important at the secondary school they attended. The greatest barrier to conducting SAE was their lack of familiarity with newer SAE categories. This was true at both the beginning and end of the course. It is recommended that preservice teachers receive instruction on and experiences in all types of SAE. This would increase the likelihood of preservice teachers perceiving they have control over this barrier regarding SAE implementation. This cohort of preservice teachers should be surveyed over time to determine change in their perceptions of barriers to SAE implementation as they progress in the agricultural education program and through their careers. Further, the views of in-service teachers should also be assessed to determine if perceived barriers differ with professional experience.

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

Approach: There were two objectives for this study .The first objective of this study was to identify the effective factors in achieving sustainable agriculture. The second objective was to categorize the effective factors in achieving sustainable agriculture. In this study the Delphi technique has been used. Sustainable agriculture expert researchers of statistical and related issues were 56 scholars selected from the experts in the research centers of Tehran and Yazd provinces. The instruments used in data collection were three series of questionnaires sent to the researchers via email, fax and mail. Results: Findings have shown that the researchers have identified effective factors in achieving sustainable agriculture in Iran as the sections of Infrastructure, policy-making, economy, society, participation, research, extension and education. From the 35 factors exposed to the researchers, the factors of attainment of researches related to sustainable agriculture by agricultural research institutions in Iran, Interaction and participation of researchers, extension educators, farmers and policy-makers of sustainable agriculture, attempt to give priority to those who are the most appropriate from the standpoint of practically creating interactive, logical as well as flexible planning system between different sections dealing with sustainable agriculture have gained the agreement of 100% researchers. Conclusion: The important conclusion is that the communication between extension, farmers and policymaker should be strengthened. So

    2006-01-01

    The article explores the importance of agricultulture in line with development of society. It uses examples of high productivity achieved in grain and cotton crops in lnner Mongolia and Xinjiang areas to show that the fundamental objective of agricultural science is to maximize crops through the most effective use of soil, fertilizer and water in gaining the greatest benefit from power of the sun. Agricultural science should take up relevant theories and methodologies from other sciences, such as biological science, earth science and economics. The use of information technology will have great benefits for agricultural science. It hopes the scientific communities of China can make a significant contribution to solving the problems facing our rural areas, farmers and agriculture itself.

    2015-01-01

    Background The influence of previous alcohol (ethanol) drinking experience on increasing the rate and amount of future ethanol consumption might be a genetically-regulated phenomenon critical to the development and maintenance of repeated excessive ethanol abuse. We have recently found evidence supporting this view, wherein inbred C57BL/6J (B6) mice develop progressive increases in the rate of binge-ethanol consumption over repeated Drinking-in-the-Dark (DID) ethanol access sessions (i.e. ‘front-loading’). The primary goal of the present study was to evaluate identical parameters in High Alcohol Preferring (HAP) mice to determine if similar temporal alterations in limited-access ethanol drinking develop in a population selected for high ethanol preference/intake under continuous (24hr) access conditions. Methods Using specialized volumetric drinking devices, HAP mice received 14 daily 2 hour DID ethanol or water access sessions. A subset of these mice was then given one day access to the opposite assigned fluid on day 15. Home cage locomotor activity was recorded concomitantly on each day of these studies. The possibility of behavioral/metabolic tolerance was evaluated on day 16 using experimenter administered ethanol. Results The amount of ethanol consumed within the first 15 minutes of access increased markedly over days. However, in contrast to previous observations in B6 mice, ethanol front-loading was also observed on day 15 in mice that only had previous DID experience with water. Furthermore, a decrease in the amount of water consumed within the first 15 minutes of access compared to animals given repeated water access was observed on day 15 in mice with 14 previous days of ethanol access. Conclusions These data further illustrate the complexity and importance of the temporal aspects of limited-access ethanol consumption, and suggest that previous procedural/fluid experience in HAP mice selectively alters the time course of ethanol and water consumption

  8. Applications of radioisotopes in agriculture

    International Nuclear Information System (INIS)

    India has large population which is engaged in agriculture or related activities. With many agro-climatic zones, diversity in crops and traditional largely plant food based diets, there is need to meet these and increase agricultural production in the face of increasing constraints. Radiations and radioisotopes can contribute significantly to these developments. Mutation breeding is very useful technique in Indian context. Basic technique can be applied where a radiation source or irradiation service and facility to grow few thousand plants are available. Radiation processing can save the valuable food which is subject to spoilage by microbes and insects. Value addition by export is possible by meeting the quarantine and hygienisation conditions

    Describing temporal relations between perceptual and emotional elements underlying responses to infant crying is important to our understanding of sensitive parenting. Prior research on adults' responses to infant crying has mostly relied on playback and snapshot approaches to obtaining recall of responses following exposure to relatively short cry stimuli. This study documented continuous temporal relations in the perception of the infant's distress and affect-related processes in response to a 4-min-long bout of crying. Three visual-analog slider scales were used to collect 90 participants' real-time responses on perceived aversiveness of the cry, empathic concern for the infant, and personal distress elicited by the cry, respectively. The results highlighted a moderating role of empathic concern at certain second in the relation between personal distress and empathic concern at the following second. In addition, personal distress moderated the relation between concurrent perceived aversiveness and empathic concern. The findings carry potentially important implications for cognitive and emotional regulation in adaptive parenting. PMID:26705932

  11. Plutonium safety training course

    International Nuclear Information System (INIS)

    This course seeks to achieve two objectives: to provide initial safety training for people just beginning work with plutonium, and to serve as a review and reference source for those already engaged in such work. Numerous references have been included to provide information sources for those wishing to pursue certain topics more fully. The first part of the course content deals with the general safety approach used in dealing with hazardous materials. Following is a discussion of the four properties of plutonium that lead to potential hazards: radioactivity, toxicity, nuclear properties, and spontaneous ignition. Next, the various hazards arising from these properties are treated. The relative hazards of both internal and external radiation sources are discussed, as well as the specific hazards when plutonium is the source. Similarly, the general hazards involved in a criticality, fire, or explosion are treated. Comments are made concerning the specific hazards when plutonium is involved. A brief summary comparison between the hazards of the transplutonium nuclides relative to 239Pu follows. The final portion deals with control procedures with respect to contamination, internal and external exposure, nuclear safety, and fire protection. The philosophy and approach to emergency planning are also discussed

    Full Text Available Problem statement: Without doubt, it is important to expose and educate farmers with the current and updated agriculture information. To implement this, the related agriculture agencies in Malaysia should consider the best channels for them in spreading the needed valuable agriculture information to the farmers. The question that can be raised now, can the mass media be the right channel for agriculture information dissemination and is the mass media has been utilized in disseminating the agriculture information to the farmers. Approach: This is a conceptual study discussing the usage of mass media in disseminating agriculture information. The data of this study are gained through literature analysis and document analysis. The data is presented descriptively. Results: Based on the analyses done, it was found that majority of Malaysian nowadays can afford to own their own mass media such as television, radio and internet. The number of available television channels, radio channels and newspapers either free or paid are encouraging. Currently, there are three television agriculture programs aired on RTM, while currently there are five agriculture radio programs aired on local radio stations, one program aired on Klasik National FM and the other four programs aired on four different states FM. For newspapers, there are two daily newspapers that provide agriculture information to their readers namely Utusan Malaysia and Berita Harian. Based on the data gained, usage of internet especially on website surfing must be encouraged among the farmers. Mobile web system initiated by five agriculture agencies in Malaysia is seen as a wise step for information dissemination and information sharing. Conclusion: Even though mass media in Malaysia has played its role in disseminating agriculture information, the number of programs and spaces produced and provided can be doubled, hence it is recommended that local giant agriculture based companies can play their

    Full Text Available Problem statement: Considering unsustainable agricultural conditions of Iran and organizational recession and inability of current extension organization to achieve sustainability, it seems that extension systems require a new organizational structure to achieve sustainability objectives. The purpose of the present study was to identify the most appropriate characteristics for extension organization toward green agriculture in Iran context. Approach: To fulfill this objective, a sample of 120 respondents was selected through simple random sampling technique. A survey study was applied as a methodology of research. A mailed questionnaire was used to collect the data. The response rate of questionnaire was 65.83% (N = 79. Appropriate descriptive statistics such as mean scores, standard deviations and variation ratio were used. Results: Extension experts believed that among important organizational characteristics of extension system for supporting green agriculture collaboration among research, extension, education organizations, farmers' associations, NGOs, rural credit agencies, transportation companies, considering local groups and learning organization had very high importance for supporting green agriculture. According to factor analysis, the implications for extension organization were categorized into two groups consisting: (1 Holistic organizations (2 Participatory organizations that those factors explained 67.54% of the total variance of the research variables. Conclusion: Identifying suitable extension mechanisms had important role for developing extension system. Therefore, identifying extension organizational characteristics for supporting green agriculture of Iran is one of the major approaches needs to be carefully thought and accurately implemented for the extension system development.

    Introduction Inflammatory pseudotumor (IPT) of the liver is a rare and benign disease that has a good prognosis. It is often difficult to distinguish IPT from hepatic malignancies, such as hepatocellular carcinoma (HCC), because specific clinical symptoms are absent and the diseases’ radiological findings can be similar. IPT is particularly difficult to distinguish from HCC in livers with hepatitis C virus (HCV)-related cirrhosis. We report a case of IPT of the liver that mimicked HCV-related HCC recurrence. Presentation of case A 78-year-old asymptomatic Japanese man who had undergone hepatectomy for HCV-related HCCs (moderately differentiated type) in segments 7 and 5 four and a half years previously was referred to our hospital for treatment of a 30-mm enhanced tumor in segment 5 (a typical HCC pattern). The tumor was identified via abdominal dynamic computed tomography (CT) and CT with hepatic arteriography and arterial portography. Thereafter, liver segmentectomy 5 was performed, and the histopathological diagnosis was a 10-mm IPT of the liver. After 1.5 years, magnetic resonance imaging revealed two new enhanced lesions in segment 8, which showed the typical pattern of HCC. Because these lesions grew in size for 3 months, liver segmentectomy 8 was performed for HCC recurrence. Histopathological examination showed that both lesions were HCCs. Conclusion HCV-related HCC has a high rate of multicentric recurrence. Our experience suggests that, when a hepatic lesion is suspected to be HCC, surgical resection should be considered for curative treatment and to rule out malignancy, even if the lesion may be an IPT.

    The objectives of the project were: To determine the admixing levels for different peat classes to various energy crops (straw, Salix and Reed canary grass) that are required to reach positive effects regarding slagging, deposit formation/(high temperature corrosion) and bed agglomeration; and, To demonstrate the possibilities to reduce the occurrence of ash related operational problems in combustion of energy crops upon admixing peat. Operational experiences and research of effects of co-firing peat and energy crops are scarce. Some previous tests in bench scale indicated though, on a strong reduction of the agglomeration tendency and lowering of the agglomeration temperature for straw and Salix at a peat admixing level corresponding to 15 - 20 weight% (on DS basis). A reduction in the amount of emitted fine particles was also observed in these experiments. However, care must be taken in the choice of peat. Some Carex dominated peats with high Si contents may cause problems with slagging. Another conclusion from the mentioned bench scale tests was that peats with relative high Ca/Si ratios should be selected to minimize the risk of slagging and bed agglomeration. Thermochemical modelling was performed to determine the effects of peat admixture, on slagging-, deposit formation- (corrosion)- and bed agglomeration tendencies during combustion of straw, willow and reed canary grass with high and low ash content. These results and previously conducted bench scale experiments were used as a basis for determining combinations of fuel and peat admixtures for the demonstration experiments. The calculations were performed with admixing levels of 0-, 5-, 15, 25-, and 40 weight% (on DS basis) of four peat samples to the investigated four crop fuels. The used peat samples were typical carex-containing Swedish peat with differences in e.g. silicon-, calcium- and sulfur contents. A number of the model calculations were qualitatively validated against previously conducted

    2013-03-01

    1. Introduction Better information on greenhouse gas (GHG) emissions and mitigation potential in the agricultural sector is necessary to manage these emissions and identify responses that are consistent with the food security and economic development priorities of countries. Critical activity data (what crops or livestock are managed in what way) are poor or lacking for many agricultural systems, especially in developing countries. In addition, the currently available methods for quantifying emissions and mitigation are often too expensive or complex or not sufficiently user friendly for widespread use. The purpose of this focus issue is to capture the state of the art in quantifying greenhouse gases from agricultural systems, with the goal of better understanding our current capabilities and near-term potential for improvement, with particular attention to quantification issues relevant to smallholders in developing countries. This work is timely in light of international discussions and negotiations around how agriculture should be included in efforts to reduce and adapt to climate change impacts, and considering that significant climate financing to developing countries in post-2012 agreements may be linked to their increased ability to identify and report GHG emissions (Murphy et al 2010, CCAFS 2011, FAO 2011). 2. Agriculture and climate change mitigation The main agricultural GHGs—methane and nitrous oxide—account for 10%-12% of anthropogenic emissions globally (Smith et al 2008), or around 50% and 60% of total anthropogenic methane and nitrous oxide emissions, respectively, in 2005. Net carbon dioxide fluxes between agricultural land and the atmosphere linked to food production are relatively small, although significant carbon emissions are associated with degradation of organic soils for plantations in tropical regions (Smith et al 2007, FAO 2012). Population growth and shifts in dietary patterns toward more meat and dairy consumption will lead to

    The level of uptake and use of personal protective equipment (PPE) by farm workers in Oman is low; the conditions under which pesticides are stored are frequently below acceptable international standards. Research was undertaken to explore the drivers working against safe storage of agrochemicals and effective personal protection usage by pesticide application personnel. Results from a survey of over 200 respondents, representing workers in, and owners of, farms either within or outside a local farmer's association (FA), suggest that FA membership raises standards of behaviour both in terms of safe pesticide storage and use of PPE. Age of respondents had no apparent effect on the likelihood of PPE (gloves and masks) use. PPE use was, however, highest among respondents with more advanced educational backgrounds. Positive responses for glove and mask use, when applying pesticides, were higher for owners and workers in FA farms compared to non-FA farms. Lowest reported use of PPE was among workers in non-FA farms. Analysis of responses appears to indicate that behaviour patterns of workers in FA farms mirror that of the farm owners. This was not the case in non-FA farms. The results suggest that conformity to social norms, in this case acceptable work-environment behaviour, is a powerful driver behind raised usage levels of PPE in farms in Oman. - Highlights: • Pesticide-related safety standards are frequently poor on many farms in Northern Oman. • Pesticides are frequently stored within the living accommodation of farm workers. • Safety standards generally increase with the education status of farm workers. • A local farmers’ association (FA) has the effect of raising safety standards on member’s farms. • FA farm workers are more likely to conform to the behaviour shown by owners of FA farms.

    1996-07-01

    Full Text Available This paper provides an overview of the use of machine vision in agriculture. Agriculture is practised in a more natural environment than most industrial undertakings, implying that agricultural automation requires robotic systems with well developed sensory abili­ties. For such systems, machine vision is an essential component. In this paper examples are used to show that the use of machine vision is already widespread in agriculture, and that there are many more potential applications for this technology. It is also indicated that machine vision in agriculture does not only hold potential financial advantages, but that it can also contribute to improved quality of life for agricultural workers, and even for farm animals.

  15. Agricultural drainage water quality

    International Nuclear Information System (INIS)

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

  16. Water and Agriculture

    Directory of Open Access Journals (Sweden)

    Wulf Klohn

    1999-10-01

    Full Text Available The growing scarcity of water resources causes concern, especially with reference to agriculture-related applications. Such scarcity is not due to hydrological reasons, but goes back to the dynamics of human society and the way in which the resource is used. Thisarticle emphasizes the basic facts of this dynamic. For instance, while total quantity of water available yearly on our planet has not changed significantly, the human population has increased greatly –consequently, the quantity of water available per person is inferior.Natural disasters multiply themselves and have a greater resonance, perhaps helped by a climatic change, and their impact on society is dramatic. The human beings affected by disasters are generally not only the poorest, but are constrained to living on steep hills,along river beds that easily flood, and in arid regions of scarce productive potential. Beyond this, the volume of water appropriated in one way or another for human use is already considerable and the rhythm of water appropriation cannot be extended towards the future. Irrigation for agriculture itself amounts to about 70% of all water extraction. Our civilization, capable of exploring the solar system, has the technological solutions to the water problems, but the levels of costs and of the necessary social organization for their application make these solutions available only to the richest societies. The technical, economic and social solutions to overcome the water global crisis exist, but their application requires the existence of a political will, and, in many cases, of international cooperation. At present, such political will appears hesitant, and multilateral international cooperation is undergoing a deep crisis. It is necessary for a public opinion to be formed on these topics so that it can find expression at a political level.

  17. Gaining control: changing relations between executive control and processing speed and their relevance for mathematics achievement over the course of the preschool period

    Directory of Open Access Journals (Sweden)

    2014-02-01

    Full Text Available Early executive control (EC predicts a range of academic outcomes and shows particularly strong associations with children's mathematics achievement. Nonetheless, a major challenge for EC research lies in distinguishing EC from related cognitive constructs that also are linked to achievement outcomes. Developmental cascade models suggest that children's information processing speed is a driving mechanism in cognitive development that supports gains in working memory, inhibitory control and associated cognitive abilities. Accordingly, individual differences in early executive task performance and their relation to mathematics may reflect, at least in part, underlying variation in children's processing speed. The aims of this study were to: 1 examine the degree of overlap between EC and processing speed at different preschool age points; and 2 determine whether EC uniquely predicts children's mathematics achievement after accounting for individual differences in processing speed. As part of a longitudinal, cohort-sequential study, 388 children (50% boys; 44% from low income households completed the same battery of EC tasks at ages 3, 3.75, 4.5 and 5.25 years. Several of the tasks incorporated baseline speeded naming conditions with minimal EC demands. Multidimensional latent models were used to isolate the variance in executive task performance that did not overlap with baseline processing speed, covarying for child language proficiency. Models for separate age points showed that, while EC did not form a coherent latent factor independent of processing speed at age 3 years, it did emerge as a distinct factor by age 5.25. Although EC at age 3 showed no distinct relation with mathematics achievement independent of processing speed, EC at ages 3.75, 4.5 and 5.25 showed independent, prospective links with mathematics achievement. Findings suggest that EC and processing speed are tightly intertwined in early childhood. As EC becomes progressively

    Full Text Available After becoming self-standing state one of new needs of Croatia important for agricultural profession, farmers, policy makers and public needs was regionalization of agriculture. It is the analyse of state of agroecological conditions in agrosphere and based on results identification and territorial separation of agricultural regions as parts of agrosphere with similar conditions for plant and animal growing and similar farming systems. On this track within a special project we fi nished an inventory of agrosphere, result of which is Regionalisation of Croatian Agriculture presented in this paper. Following wise message of old Chinese proverb cited above, the starting approach is the MFCAL concept (Multifunctional Character of Agriculture and Land, which means that apart from very important and primary economic, agriculture and agricultural land (soil in human life play other roles (functions of similar importance; environmental, social, cultural and spatial, as well as the role of shaping the cultural landscape as a factor of rural development. As well, we respect the point of view prevailing in EU that all natural resources used in agriculture but at the fi rst place soil as a major one, need sustainable use and efficient protection. Using the data on Land resource potential based primarily on data of General Soil Map of Croatia (GSM in a scale of 1:50 000 and results of our research in the period 2000 – 2003, the agrosphere of Croatia is divided in three agricultural regions; Pannonian with four, Mountain with two and Adriatic with three subregions.

    2009-04-01

    An engineering education should prepare students, i.e., emerging engineers, to use problem-solving processes that combine creativity and imagination with rigour and discipline. The emphasis on training engineers may be best placed on answering the needs of industry; indeed, many proposals are now being made to try to reduce the gap between the educational and industrial communities. Training in the use of certain skills or competences may be one way of better preparing engineering undergraduates for eventual employment in industry. However, industry's needs in this respect must first be known. The aim of this work was to determine which skills are used by practising agricultural engineers with the aim of incorporating training in their use into our department's teaching curriculum. Three surveys were undertaken to determine which skills are demanded by agricultural engineers in their professional activities in Spain. Surveys were carried out by the Department of Rural Engineering, Technical University of Madrid (Spain), analysing two related degrees (agricultural engineer with a duration of the study plan of three and five years, respectively) during the courses 2006/07 and 2007/08. The first survey determined the competences acquired by the students along their academic studies (371 students interviewed). The second survey determined the skills demanded by the enterprises of the agricultural sector (50 enterprises interviewed). The third survey determined the skills demanded by the agricultural engineers working in the sector (70 engineers interviewed), specifically asking about the computer programs used by practising agricultural engineers. Surveys showed important differences between the competences demanded by the enterprises and the competences acquired by the students at the university. Enterprises mainly demanded general competences (team working, time organizing, and skills with computer programs) and were less interested in specific technical skills

    Science.gov (United States)

    Yagasaki, Y.; Shirato, Y.

    2014-08-01

    Future potentials of the sequestration of soil organic carbon (SOC) in agricultural lands in Japan were estimated using a simulation system we recently developed to simulate SOC stock change at country-scale under varying land-use change, climate, soil, and agricultural practices, in a spatially explicit manner. Simulation was run from 1970 to 2006 with historical inventories, and subsequently to 2020 with future scenarios of agricultural activity comprised of various agricultural policy targets advocated by the Japanese government. Furthermore, the simulation was run subsequently until 2100 while forcing no temporal changes in land-use and agricultural activity to investigate duration and course of SOC stock change at country scale. A scenario with an increased rate of organic carbon input to agricultural fields by intensified crop rotation in combination with the suppression of conversion of agricultural lands to other land-use types was found to have a greater reduction of CO2 emission by enhanced soil carbon sequestration, but only under a circumstance in which the converted agricultural lands will become settlements that were considered to have a relatively lower rate of organic carbon input. The size of relative reduction of CO2 emission in this scenario was comparable to that in another contrasting scenario (business-as-usual scenario of agricultural activity) in which a relatively lower rate of organic matter input to agricultural fields was assumed in combination with an increased rate of conversion of the agricultural fields to unmanaged grasslands through abandonment. Our simulation experiment clearly demonstrated that net-net-based accounting on SOC stock change, defined as the differences between the emissions and removals during the commitment period and the emissions and removals during a previous period (base year or base period of Kyoto Protocol), can be largely influenced by variations in future climate. Whereas baseline-based accounting, defined
