  6. The effects of the African Green Revolution on nitrogen losses from two contrasting soil types in sub-Saharan Africa

    Nearly 80% of countries in sub-Saharan Africa (SSA) face problems of nitrogen (N) scarcity, which together with poverty causes food insecurity and malnutrition. The Alliance for a Green Revolution in Africa has set a goal of increasing fertilizer use in the region six-fold by 2015. While there is substantial evidence that greater N fertilizer use will improve crop yields, it could lead to increased N leaching and elevated nitrate (NO3-) concentrations in surface water and groundwater reservoirs. However, it is unclear what the magnitude of impacts will be in SSA given historically low nutrient additions (of less than 5 kg N/ha/yr), highly degraded soils (due to years of nutrient and soil organic matter depletion), and a wide range of soil types on which increased fertilizer use is occurring. Current estimates of N dynamics and balances in SSA agriculture now rely on data from other regions with different soil types, soil fertility, and land management practices. To understand the influence of increased fertilizer use on water quality requires data from representative areas in SSA. Experimental maize plots were established in a randomized complete block design in both western Kenya (clayey soil) and mid-western Tanzania (sandy soil). Plots were amended with 0, 50, 75, and 200 kg N/ha/yr as mineral fertilizer. Tension lysimeters were installed at three depths in each treatment, and water was collected throughout the maize growing season. Soil water solutions were analyzed for NO3--N. Flow through the soil column at each soil depth, was modeled using VS2DT, a variably saturated flow and solute transport model, and water flux values were multiplied by measured NO3--N concentrations to estimate seasonal N leaching flux. Soil texture was a major driver of N losses, altering both the pathways and magnitude of losses. Clayey soils in western Kenya show an enormous potential for loss of NO3--N immediately following the onset of rains as they trigger high rates of N

    Full Text Available This paper presents the milestones of the Green Revolution, outlining its role in the development of today's sustainable and biotechnological agriculture. In order to do this we used the material found in papers and books on the research in agriculture from the 1940s to the late 1980s. Current sustainable agriculture and biotechnological advancement, incuding the creation of genetically modified organisms could never have been possible without the Green Revolution. Reducing the height of the stalk allowed the production of high-yielding cultivars that now are used and modified with genetic engeneering methods in the context of a sustainable agriculture.

  13. Impacts of an African Green Revolution on Greenhouse Gases and Pollution Precursors: Nonlinear Trace N Gas Emission Responses to Incremental Increases in Fertilizer Inputs in a Western Kenyan Maize Field

    Science.gov (United States)

    Hickman, J. E.; Palm, C.

    2011-12-01

    Over the last several decades, agricultural soils in many parts of sub-Saharan Africa have become depleted of nitrogen (N) and other nutrients, creating challenges to achieving food security in many countries. At only 7 kg N ha-1 yr-1, average fertilizer application rates in the region are an order of magnitude lower than typical rates in the United States, and well below optimal levels. Increased use of nutrient inputs is a centerpiece of most African Green Revolution strategies, making it important to quantify the impacts of this change in practices as farmers begin moving towards 50-80 kg N ha-1 yr-1. Increased N inputs are invariably accompanied by losses of trace N gases to the atmosphere, including the greenhouse gas nitrous oxide (N2O), and nitric oxide (NO), a precursor to tropospheric ozone pollution. Several investigations of greenhouse gas emissions and one investigation of NO emissions from sub-Saharan agricultural systems have been conducted over the last 20 years, but they are few in number and were not designed to identify potentially important thresholds in the response of trace gas emissions to fertilization rate. Here we examine the response function of NO and N2O emissions to 6 different levels of inorganic fertilizer additions in a maize field in Yala, Kenya during the 2011 long rainy season. We used a randomized complete block design incorporating inorganic fertilizer treatments of 0, 50, 75, 100, 150, and 200 kg N ha-1 in 4 blocks. After each of 2 fertilizer applications, we measured trace gas fluxes daily, and conducted weekly measurements until trace gas emissions subsided to control levels. We fit the data to linear and exponential models relating N gas emissions to N input levels, and conducted a model comparison using AIC. Preliminary analysis suggests that NO emissions do respond in a non-linear fashion over the course of 67 days, as has been found in several commercial agroecosystems for N2O. Although N2O emissions responded linearly

    Khush, G S

    1999-08-01

    In the 1960s there were large-scale concerns about the world's ability to feed itself. However, widespread adoption of "green revolution" technology led to major increases in food-grain production. Between 1966 and 1990, the population of the densely populated low-income countries grew by 80%, but food production more than doubled. The technological advance that led to the dramatic achievements in world food production over the last 30 years was the development of high-yielding varieties of wheat and rice. These varieties are responsive to fertilizer inputs, are lodging resistant, and their yield potential is 2-3 times that of varieties available prior to the green revolution. In addition, these varieties have multiple resistance to diseases and insects and thus have yield stability. The development of irrigation facilities, the availability of inorganic fertilizers, and benign government policies have all facilitated the adoption of green-revolution technology. In the 1990s, the rate of growth in food-grain production has been lower than the rate of growth in population. If this trend is not reversed, serious food shortages will occur in the next century. To meet the challenge of feeding 8 billion people by 2020, we have to prepare now and develop the technology for raising farm productivity. We have to develop cereal cultivars with higher yield potential and greater yield stability. We must also develop strategies for integrated nutrient management, integrated pest management, and efficient utilization of water and soil resources. PMID:10464789

    Despite recent achievements in conventional plant breeding and genomics, the rate of increase of crop yields is declining and thus there is a need for a second green revolution. Advances within single disciplines, alone, cannot solve the challenges of increasing yield. As scientific disciplines have become increasingly diversified, a more complete understanding of the mechanisms by which genetic and environmental variation modify grain yield and composition is needed, so that specific quantitative and quality targets can be identified. To achieve this aim, the expertise of plant genomics, physiology and agronomy, as well as recently developed plant modelling techniques, must be combined. There has been recent progress in these individual disciplines, but multidisciplinary approaches must be implemented to tackle drought stress and salinity as major constraints to achieving sufficient grain yield in the future.

    Green Revolution made a substantial contribution to wheat yields worldwide in the 1960s and 1970s. It is of great importance to analyze the haplotype variation of Rht-D1, the Green Revolution gene, during wheat (Triticum aestivum L.) domestication and breeding to understand its evolution and function in wheat breeding history. In this study, the Rht-D1 and its flanking regions were sequenced and single nucleotide polymorphisms were detected based on a panel of 45 accessions of Aegilops tauschi , 51 accessions of landraces and 80 accessions of commercial varieties. Genetic diversity in the wild accessions was much higher than that in the varieties and higher than that reported previously. Seven haplotypes (Hapl I to Hapl VII) of Rht-D1 were identified and their evolutionary relationships were proposed. In addition to the wel-known Green Revolution al ele Rht-D1b, Hapl VII (an al ele Rht-D1k) was identified in early breeding varieties, which reduced plant height by 16%. The results suggested that Rht-D1k had been used in breeding before the Green Revolution and made a great contribution to wheat production worldwide. Based on the breeding history and molecular evidence, we proposed that the wheat Green Revolution in China and International Maize and Wheat Improvement Center (CIMMYT) occurred independently.

    The "green revolution" was desirable because of increased crop yields, but 25 years later after the results of land degradation, groundwater contamination, and environmentally harmful practices were revealed, there is a return to sustainable agriculture. The aim is to minimize agriculture's harmful effects on the environment and to maintain water ad soil resources. Present and future food production depends on suitable land, water, climate, and finances. Unfortunately, the timing is wrong. Population growth is putting pressure on farmers to increase yields. The current conditions are the 11% of the earth's vegetative land surface has diminished productivity due to human activity. There is loss of biodiversity and genetic material. CAttle grazing is inefficient and adds to desertification; animal waste contributes to pollution. Pesticides and fertilizers are the largest US water pollutants. Sustainable agriculture means new tilling methods, reducing pesticide use, and crop rotation. The National Research Council in 1989 reported on alternative agriculture: 1) making the most of natural biological processes; 2) reducing or eliminating pesticides and other chemicals; 3) conserving soil, water, and energy; and 4) matching crops with land to ensure sustainable production levels. Reeducation is needed. Operation SAVE (Sustainable Agriculture that's Voluntary and Economical) produces an annual directory and guide for farmers adopting new methods. Land trusts and conservation easements are being established to preserve farmland. Reclamation of degraded land is being promoted by distribution of tree seedlings to developing countries. Community supported agriculture groups share in the cost of raising crops and receive organic, fresh produce. There are fears about economic feasibility. Conventional farmers argue for pesticide use to increase yields, but a Cornell University study refutes this for organically grown corn. High technology research is not likely to yield a new

    2009-01-01

    Despite extensive literature both supporting and critiquing the Green Revolution, surprisingly little attention has been paid to synthetic fertilizers' health and environmental effects or indigenous farmers' perspectives. The introduction of agrochemicals in the mid-twentieth century was a watershed event for many Mayan farmers in Guatemala. While some Maya hailed synthetic fertilizers' immediate effectiveness as a relief from famines and migrant labor, other lamented the long-term deterioration of their public health, soil quality, and economic autonomy. Since the rising cost of agrochemicals compelled Maya to return to plantation labor in the 1970s, synthetic fertilizers simply shifted, rather than alleviated, Mayan dependency on the cash economy. By highlighting Mayan farmers' historical narratives and delineating the relationship between agricultural science and postwar geopolitics, the constraints on agriculturists' agency become clear. In the end, politics, more than technology or agricultural performance, influenced guatemala's shift toward the Green Revolution. PMID:19824230

    Full Text Available Mutagenesis is a powerful tool used for studying gene function as well as for crop improvement. It is regaining popularity because of the development of effective and cost efficient methods for high-throughput mutation detection. Selection for semi-dwarf phenotype during green revolution has reduced genetic diversity including that for agronomically desirable traits. Most of the available mutant populations in wheat (Triticum aestivum L. were developed in post-green revolution cultivars. Besides the identification and isolation of agronomically important alleles in the mutant population of pre-green revolution cultivar, this population can be a vital resource for expanding the genetic diversity for wheat breeding. Here we report an Ethylmethane Sulfonate (EMS generated mutant population consisting of 4,180 unique mutant plants in a pre-green revolution spring wheat cultivar 'Indian'. Released in early 1900s, 'Indian' is devoid of any known height-reducing mutations. Unique mutations were captured by proceeding with single M2 seed from each of the 4,180 M1 plants. Mutants for various phenotypic traits were identified by detailed phenotyping for altered morphological and agronomic traits on M2 plants in the greenhouse and M3 plants in the field. Of the 86 identified mutants, 75 (87% were phenotypically stable at the M4 generation. Among the observed phenotypes, variation in plant height was the most frequent followed by the leaf morphology. Several mutant phenotypes including looped peduncle, crooked plant morphology, 'gritty' coleoptiles, looped lower internodes, and burnt leaf tips are not reported in other plant species. Considering the extent and diversity of the observed mutant phenotypes, this population appears to be a useful resource for the forward and reverse genetic studies.

    The semidwarf phenotype has been extensively selected during modern crop breeding as an agronomically important trait. Introduction of the semidwarf gene, semi-dwarf1 (sd1), which encodes a gibberellin biosynthesis enzyme, made significant contributions to the "green revolution" in rice (Oryza sativa L.). Here we report that SD1 was involved not only in modern breeding including the green revolution, but also in early steps of rice domestication. We identified two SNPs in O. sativa subspecies (ssp.) japonica SD1 as functional nucleotide polymorphisms (FNPs) responsible for shorter culm length and low gibberellin biosynthetic activity. Genetic diversity analysis among O. sativa ssp. japonica and indica, along with their wild ancestor O. rufipogon Griff, revealed that these FNPs clearly differentiate the japonica landrace and O. rufipogon. We also found a dramatic reduction in nucleotide diversity around SD1 only in the japonica landrace, not in the indica landrace or O. rufipogon. These findings indicate that SD1 has been subjected to artificial selection in rice evolution and that the FNPs participated in japonica domestication, suggesting that ancient humans already used the green revolution gene.

  11. The green bubble: waste into wealth: the new energy revolution

    International Nuclear Information System (INIS)

    In this exhaustive (and exhausting) look at the future of energy, Bell, a professor of management and chairman of the economics department at Brooklyn College, CUNY, maps a complicated future for investors and laymen with clear-eyed examination of failed U.S. environmental policy and worldwide efforts to break away from oil. Under discussion are a wide range of topics: the stampede away from oil; wind energy and turbines; photovoltaic opportunities; what car-makers are saying and what they're actually doing (including a careful look at the popular Toyota Prius); the extremely lengthy timetables for new energy-saving technologies to get off the ground; and the processes, research and expectations tied up in them all. Drawing an analogy to the dot-com debacle, Bell predicts investment in the hot properties of energy tech will lead to a bubble effect, eventually draining the financial resources of investors who linger too long. Frequently fascinating anecdotes-as in the story of Sweden's green welfare state and bicycles of Lyon-buoy what otherwise can read like a university course. Bell's latest (following 2003's The Stock Market Sting) is an educated, opinionated tour through the future of energy economics that should shore up the will and wisdom of investors, as well as open the eyes of average Americans.

    While the Green Revolution has been successful in some regions like South and East Asia, it could hardly address any achievement in Sub-Saharan Africa (SSA). This paper tries to draw a picture on lessons learned from the failures of this revolution that should be taken into account before implementing the so-called Gene Revolution in the SSA region. After scrutinizing the failures and the pros and cons of GM crops in the region, the paper introduces some potentials for improving the malnutrition situation in SSA through launching a successful GM technology. However, it remains doubtful whether this technology can improve the situation of small-scale farmers as long as they receive no financial support from their national governments. Therefore, before any intervention, the socio-economic and environmental impacts of GM technology need to be carefully addressed in the framework of a series of risk assessment studies. Besides, some sort of multi-stakeholder dialog (from small-scale farmers to consumers) involving public-private sector and non-governmental organizations should be heated up at both national and regional levels with regard to the myths and truths of this technology.

Consequently, this article analyzes these questions as a framework for developing a comparative analysis between revolutions and civil rights movements as a means to understand both the intent and outcomes of the Green Movement. From this analysis, lessons learned are put forth as a means to establish a series of recommendations for future Western political engagements with Iran. In doing so, the hope is that a political dialogue will emerge between Western governments that both alleviate the current tensions while also addressing security concerns in the region.

    The development and dissemination of sawah rice eco-technology in Nigeria and Ghana as prerequisites for the actualization of green revolution in West Africa were described. It showed that the neglect of the eco-technology and the overemphasis of the biotechnology have rendered the ineffective transferability of the green revolution process from Asia to Africa. The sawah eco-technology increases yield up to 5 t/hm2 through bunding and the use of inlet and outlet connecting irrigation and drainage, which enhances effective water control and management, improves the efficiency of fertilizer, improves nitrogen fixation by soil microbes and algae, increases the use of wetlands, improves soil organic matter accumulation, suppresses weed growth, and enhances immune mechanism of rice through nutrient supply. The current experience has therefore established that the technology overcomes the constraints that have limited the realization of green revolution in West Africa.

    Post-green revolution advances made in biotechnology paved the way of cultivating the high-yielding, stress and disease resistant genetically modified (GM) varieties of wheat, rice, maize cotton and several other crops. The recent rapid commercialization of the genetically modified crops in Asia, Americas and Australia indicates the potentiality of this new technology. GM crops give higher yields and are rich in nutritional values containing vitamins and minerals and can thus can help to alleviate hunger and malnutrition of the growing population in the under developed and developing countries. It could also be possible to develop more biotic and abiotic stress resistant genotypes in these crops where it was difficult to develop due to the unavailability of genes of resistance in the crossing germplasms. However, further research and investigations are needed to popularize the cultivation of these crops in different parts of the world. This review provides an insight of the impact of GM crops on contemporary agriculture across the past few decades, traces its' history across time, highlights new achievements and breakthroughs and discusses the future implication of this powerful technology in the coming few decades.

  19. Addendum to the Agency's Annual Report to the Economic and Social Council of the United Nations for 1970-71. Nuclear Technics and the Green Revolution

    International Nuclear Information System (INIS)

    In an age beset by social and political revolutions, the Green Revolution deals with the most basic of human needs and offers scope for better balance between the growing population and its food requirements. This report takes a close look at how nuclear techniques are being utilized in modern agricultural research to augment the Green Revolution. The Green Revolution is basically the growing of new, higher yielding cereal varieties, particularly wheat and rice, in the developing countries of Asia and Latin America. Many of the new varieties were developed by plant breeders in the Philippines, the United States of America and in Mexico, among whom is Norman Borlaug, who was recently awarded die Nobel Peace Prize for his work. This report deals only with the additional scientific contribution that nuclear techniques are making and can make to sustain and expand the Green Revolution. In this sense it complements other reports dealing with the contributions of the non-nuclear techniques, which are primarily responsible for the Green Revolution.

    Cannabis is a predominantly diecious phenotypically diverse domesticated genus with few if any extant natural populations. International narcotics conventions and associated legislation have constrained the establishment, characterization, and use of Cannabis genetic resource collections. This has resulted in the underutilization of genepool variability in cultivar development and has limited the inclusion of secondary genepools associated with genetic improvement strategies of the Green Revolution. The structured screening of ex situ germplasm and the exploitation of locally-adapted intraspecific traits is expected to facilitate the genetic improvement of Cannabis. However, limited attempts have been made to establish the full extent of genetic resources available for pre-breeding. We present a thorough critical review of Cannabis ex situ genetic resources, and discuss recommendations for conservation, pre-breeding characterization, and genetic analysis that will underpin future cultivar development. We consider East Asian germplasm to be a priority for conservation based on the prolonged historical cultivation of Cannabis in this region over a range of latitudes, along with the apparent high levels of genetic diversity and relatively low representation in published genetic resource collections. Seed cryopreservation could improve conservation by reducing hybridization and genetic drift that may occur during Cannabis germplasm regeneration. Given the unique legal status of Cannabis, we propose the establishment of a global virtual core collection based on the collation of consistent and comprehensive provenance meta-data and the adoption of high-throughput DNA sequencing technologies. This would enable representative core collections to be used for systematic phenotyping, and so underpin breeding strategies for the genetic improvement of Cannabis. PMID:27524992

  1. Agricultural Green Revolution as a driver of increasing atmospheric CO2 seasonal amplitude

    The atmospheric carbon dioxide (CO2) record displays a prominent seasonal cycle that arises mainly from changes in vegetation growth and the corresponding CO2 uptake during the boreal spring and summer growing seasons and CO2 release during the autumn and winter seasons. The CO2 seasonal amplitude has increased over the past five decades, suggesting an increase in Northern Hemisphere biospheric activity. It has been proposed that vegetation growth may have been stimulated by higher concentrations of CO2 as well as by warming in recent decades, but such mechanisms have been unable to explain the full range and magnitude of the observed increase in CO2 seasonal amplitude. Here we suggest that the intensification of agriculture (the Green Revolution, in which much greater crop yield per unit area was achieved by hybridization, irrigation and fertilization) during the past five decades is a driver of changes in the seasonal characteristics of the global carbon cycle. Our analysis of CO2 data and atmospheric inversions shows a robust 15 per cent long-term increase in CO2 seasonal amplitude from 1961 to 2010, punctuated by large decadal and interannual variations. Using a terrestrial carbon cycle model that takes into account high-yield cultivars, fertilizer use and irrigation, we find that the long-term increase in CO2 seasonal amplitude arises from two major regions: the mid-latitude cropland between 25° N and 60° N and the high-latitude natural vegetation between 50° N and 70° N. The long-term trend of seasonal amplitude increase is 0.311 +/- 0.027 per cent per year, of which sensitivity experiments attribute 45, 29 and 26 per cent to land-use change, climate variability and change, and increased productivity due to CO2 fertilization, respectively. Vegetation growth was earlier by one to two weeks, as measured by the mid-point of vegetation carbon uptake, and took up 0.5 petagrams more carbon in July, the height of the growing season, during 2001-2010 than in 1961

Scientists of all over the world are exploring the possible targets of the new green revolution including improving ribulose-l,5-bisphosphate (RuBP) carboxylase/oxygenase (Rubisco), decreasing pho-torespiratory and respiratory losses, increasing RuBP regeneration capacity, changing C3 plants into C4 plants such as C4 rice, introducing the CO2 concentrating mechanism of cyanobacteria into C3 plants, increasing transporters, as well as improving crop roots, optimizing product quality, and enhancing crop resistances to environmental stresses. This review examines mainly the progress in probing these targets, and points out that the potential problems. Although the gene engineering is a powerful tool, peoples should not put all hopes of success of the new green revolution on it. Some conventional and non-transgenic methods will also play important role in the revolution. The perspective of the revolution is bright, but the time to obtain the success may be much longer than 15 years

    Full Text Available BACKGROUND: Yersinia pestis, the agent of plague, is considered a potential bioweapon due to rapid lethality when delivered as an aerosol. Levofloxacin was tested for primary pneumonic plague treatment in a nonhuman primate model mimicking human disease. METHODS AND RESULTS: Twenty-four African Green monkeys (AGMs, Chlorocebus aethiops were challenged via head-only aerosol inhalation with 3-145 (mean = 65 50% lethal (LD(50 doses of Y. pestis strain CO92. Telemetered body temperature >39 °C initiated intravenous infusions to seven 5% dextrose controls or 17 levofloxacin treated animals. Levofloxacin was administered as a "humanized" dose regimen of alternating 8 mg/kg and 2 mg/kg 30-min infusions every 24-h, continuing until animal death or 20 total infusions, followed by 14 days of observation. Fever appeared at 53-165 h and radiographs found multilobar pneumonia in all exposed animals. All control animals died of severe pneumonic plague within five days of aerosol exposure. All 16 animals infused with levofloxacin for 10 days survived. Levofloxacin treatment abolished bacteremia within 24 h in animals with confirmed pre-infusion bacteremia, and reduced tachypnea and leukocytosis but not fever during the first 2 days of infusions. CONCLUSION: Levofloxacin cures established pneumonic plague when treatment is initiated after the onset of fever in the lethal aerosol-challenged AGM nonhuman primate model, and can be considered for treatment of other forms of plague. Levofloxacin may also be considered for primary presumptive-use, multi-agent antibiotic in bioterrorism events prior to identification of the pathogen.

    Full Text Available This study seeks to explore the significant contributions of the new philanthropy towards improving the conditions of smallholder farmers in Sub-Saharan African, smallholder farmers’ understanding of philanthropy and to investigate the relationship that exists between philanthropy and smallholder farmers. The research is designed to uncover the needs and drivers of both philanthropy and smallholder farmers in relation to their interaction and the fulfilment of the philanthropic contract they have entered into. The main objective of the thesis is to consider the potential of philanthropy to rural transformation for poverty reduction. It focus is the involvement of the Bill and Melinda Gates Foundation in rural development and poverty reduction in Ghana. Since 2006 the Bill and Melinda Gates Foundation (Gates Foundation has dedicated $1.7 billion to assisting smallholder farmers. The bulk of this investment has been delivered through programmes associated with the Alliance for a Green Revolution in Africa (AGRA, which is also supported by the Rockefeller Foundation(Thompson, 2012. This study observed an inherent discrepancies and organisational miscalculations that have adverse influence on the effective collaboration and implementation of philanthropic support to the selected farmers. Untimely release of farming inputs as well as exceedingly unfavourable conditions for the attractions of loans makes it difficult for smooth farming. This exercise also established that both men and women intercrop their farms to ensure household food security and income. Household decisions on which medium of farming to pursue and on use of the income from farming are generally taken by men. Due to these, this research emphasise that philanthropic offering in Ghana should be looked at dispassionately bearing in mind the socio-culturally diverse nature of the country itself as well as key environmental factors that hugely contribute to poverty.

    Full Text Available Focusing on a study of Taiwan’s United News Daily archive and the shifting discourses of the Green Revolution and the organic food movement, the project analyzes the narrative frameworks produced on the apple snail (Pomacea canaliculata in Taiwan. Apple snail has become invasive to many East Asian countries since the 1980s; it is considered among the world’s 100 most invasive species. During the era of the Green Revolution, the economy of killing the apple snail with pesticide was generated by a narrative of how greedy merchants imported invasive apple snail and led to the systematic disruption of Taiwan’s ecology. The paper explores how the organic food movement responded to and was shaped by such a narrative of innocence lost, and emphasizes the importance of going beyond the hyper-real narratives of irreparable ecological destructions by recognizing sites of memories left behind by global capital flow.

    The endemic of chronic renal failure (CRF) emerged in 2002 in the farming provinces of Sri Lanka. An estimate of dietary cadmium intake was between 15 and 28 microg/kg body weight per week. The mean urinary cadmium in patients diagnosed with stage 5 kidney failure was 7.6 microg/g creatinine and 11.6 microg/g for asymptomatic persons. The agrochemical triple superphosphate (TSP) fertilizer containing 23.5-71.7 mg Cd/kg was the source of cadmium added to soils. Mean Cd content in cultivated vs. uncultivated soils in Anuradhapura district was 0.02 +/- 0.01 vs. 0.11 +/- 0.19 mg/kg while in Polonnaruwa district, it was 0.005 +/- 0.004 vs. 0.016 +/- 0.005 mg/kg. Prior to the Green Revolution, the amount of fertilizer used in rice cultivation in 1970 was 32,000 metric tons (Mts) rising to 74,000 Mts in 1975. Up to 68.9 Mts of Cd could have entered into the rice-cascade reservoir environment from TSP use since 1973. Diversion of the Mahaweli River in 1970-1980 further increased cadmium input. Cadmium transfer from Upper Mahaweli water to Polgolla was 72.13 kg/day. Cadmium content of the sediments from reservoirs collecting cadmium from irrigated TSP fertilized crop fields (rice and vegetables) was 1.8-2.4 mg/kg. PMID:20430069

    The Green Revolution dwarfing genes, Rht-B1b and Rht-D1b, encode mutant forms of DELLA proteins and are present in most modern wheat varieties. DELLA proteins have been implicated in the response to biotic stress in the model plant, Arabidopsis thaliana. Using defined wheat Rht near-isogenic lines and barley Sln1 gain of function (GoF) and loss of function (LoF) lines, the role of DELLA in response to biotic stress was investigated in pathosystems representing contrasting trophic styles (biotrophic, hemibiotrophic, and necrotrophic). GoF mutant alleles in wheat and barley confer a resistance trade-off with increased susceptibility to biotrophic pathogens and increased resistance to necrotrophic pathogens whilst the converse was conferred by a LoF mutant allele. The polyploid nature of the wheat genome buffered the effect of single Rht GoF mutations relative to barley (diploid), particularly in respect of increased susceptibility to biotrophic pathogens. A role for DELLA in controlling cell death responses is proposed. Similar to Arabidopsis, a resistance trade-off to pathogens with contrasting pathogenic lifestyles has been identified in monocotyledonous cereal species. Appreciation of the pleiotropic role of DELLA in biotic stress responses in cereals has implications for plant breeding.

  8. Viewpoint – Water Variability, Soil Nutrient Heterogeneity and Market Volatility – Why Sub-Saharan Africa’s Green Revolution Will Be Location-Specific and Knowledge-Intensive

    Pieter van der Zaag

    2010-02-01

    Full Text Available In his interesting Viewpoint article in Water Alternatives, Bruce Lankford suggests that an African Green Revolution cannot come about without irrigation. But he does not convincingly explain why irrigated areas expand only very slowly. This viewpoint article argues that grain yields have remained stagnant in Africa because of high temporal rainfall variability, significant spatial soil nutrient heterogeneity, and weak and volatile markets. This combination calls for location-specific interventions that are aimed at enhancing farmers’ capacity to buffer water variations and address nutrient deficits. This finding is consistent with what Lankford dismisses as an "atomised" approach, but which would preferably be called a farmer-centred approach. Thus a massive investment in African agriculture is indeed required, primarily focused on the creation of knowledge that does justice to the local variation in water and nutrient availability. It should aim to empower farmers to experiment and be innovative, and remake agricultural extension and agricultural engineering exciting with cutting-edge disciplines. Irrigation may then emerge as the right thing to do.

    Full Text Available No virar deste século foram identificados os genes responsáveis pela redução da estatura das variedades de trigo e de arroz que possibilitaram a chamada Revolução Verde dos anos sessenta. Mais recentemente, foi demonstrado que esta alteração da arquitectura das plantas resulta da ausência da acção das giberelinas, as hormonas responsáveis pelo alongamento dos entre-nós dos caules, mas enquanto que no trigo a redução da estatura das plantas foi o produto de mutações com ganho de função que interferem com a sequência de transdução das giberelinas, no caso do arroz resultou de uma mutação com perda de função que impede a síntese daquelas hormonas. Embora as giberelinas sejam por excelência as hormonas responsáveis pelo alongamento dos caules das plantas, é referido o caso de um mutante de milho em que a redução de altura é provocada por uma diminuição na disponibilidade de auxinas. Estas e outras descobertas da biologia molecular vêm municiar a nova revolução requerida na agricultura para que possa satisfazer a procura mundial crescente de alimentos, sob a pressão de uma expansão contínua de culturas para produção de energia.At the turn of this century, the genes responsible for the height reduction of the wheat and rice varieties that made possible the so-called Green Revolution of the 1960s were identified. More recently, it has been shown that this change in plant architecture results from a lack of gibberellin effects, the hormones that cause the internode elongation of stems, but whereas in wheat the reduction in size was accounted for by a gain of function mutation that interfere with the signalling pathway of the gibberellins, in the rice resulted from a loss of function mutation that prevents the synthesis of those hormones. Although gibberellins are the major hormones responsible for stem elongation, it is discussed a maize mutant in which the height reduction is caused by a decrease in auxin

    Full Text Available The function of prostate-specific antigen (PSA is to liquefy the semen coagulum so that the released sperm can fuse with the ovum. Fifteen spliced variants of the PSA gene have been reported in humans, but little is known about alternative splicing in nonhuman primates. Positive selection has been reported in sex- and reproductive-related genes from sea urchins to Drosophila to humans; however, there are few studies of adaptive evolution of the PSA gene. Here, using polymerase chain reaction (PCR product cloning and sequencing, we study PSA transcript variant heterogeneity in the prostates of chimpanzees (Pan troglodytes, cynomolgus monkeys (Macaca fascicularis, baboons (Papio hamadryas anubis, and African green monkeys (Chlorocebus aethiops. Six PSA variants were identified in the chimpanzee prostate, but only two variants were found in cynomolgus monkeys, baboons, and African green monkeys. In the chimpanzee the full-length transcript is expressed at the same magnitude as the transcripts that retain intron 3. We have found previously unidentified splice variants of the PSA gene, some of which might be linked to disease conditions. Selection on the PSA gene was studied in 11 primate species by computational methods using the sequences reported here for African green monkey, cynomolgus monkey, baboon, and chimpanzee and other sequences available in public databases. A codon-based analysis (dN/dS of the PSA gene identified potential adaptive evolution at five residue sites (Arg45, Lys70, Gln144, Pro189, and Thr203.

    Henipaviruses are implicated in severe and frequently fatal pneumonia and encephalitis in humans. There are no approved vaccines or treatments available for human use, and testing of candidates requires the use of well-characterized animal models that mimic human disease. We performed a comprehensive and statistically-powered evaluation of the African green monkey model to define parameters critical to disease progression and the extent to which they correlate with human disease. African green monkeys were inoculated by the intratracheal route with 2.5 × 10(4) plaque forming units of the Malaysia strain of Nipah virus. Physiological data captured using telemetry implants and assessed in conjunction with clinical pathology were consistent with shock, and histopathology confirmed widespread tissue involvement associated with systemic vasculitis in animals that succumbed to acute disease. In addition, relapse encephalitis was identified in 100% of animals that survived beyond the acute disease phase. Our data suggest that disease progression in the African green monkey is comparable to the variable outcome of Nipah virus infection in humans.

    2009-07-01

    The author blows the whistle about what he considers as a worldwide environmental crisis. He brings a fresh outlook to the crises of destabilizing climate change and rising competition for energy - both of which could poison our world if we do not act quickly and collectively. His argument speaks to all of us who are concerned about the state of America in the global future. The author proposes that an ambitious national strategy - which he calls 'Geo-Greenism' - is not only what we need to save the planet from overheating; it is what we need to make America healthier, richer, more innovative, more productive, and more secure. He explains a new era - the Energy-Climate era - through an illuminating account of recent events. He shows how 9/11, Hurricane Katrina, and the flattening of the world by the Internet (which brought 3 billion new consumers onto the world stage) have combined to bring climate and energy issues to Main Street. But they have not gone very far down Main Street; the much-touted 'green revolution' has hardly begun. With all that in mind, the author sets out the clean-technology breakthroughs we, and the world, will need; he shows that the energy technology revolution will be both transformative and disruptive; and he explains why America must lead this revolution - with the first Green President and a Green New Deal, spurred by the Greenest Generation. This book is fearless, incisive, forward-looking, and rich in surprising common sense about the world we live in today.

    Human activities has tranformed the Earth's surface in complex ways. Here we show that not only land cover change, but also the management intensity, namely the intensification of agriculture through the Green Revolution has had a profound impact on the carbon cycle. A long-standing puzzle in the global carbon cycle is the increase in the amplitude of the seasonal cycle of atmospheric CO2. This increase likely reflects enhanced biological activity in the Northern Hemisphere (NH). It has been hypothesized that vegetation growth may have been stimulated by higher concentrations of CO2 as well as warming in recent decades, but the role of such specific mechanisms has not been quantified and they have been unable to explain the full range and magnitude of observations. Here we suggest another potential driver of the increased seasonal amplitude: the intensification of agriculture from the Green Revolution to feed a rising population, that led to a 3-fold increase in world crop production over the last 5 decades. Our analysis of CO2 data and atmospheric inversions shows a robust 15% long-term increase in CO2 seasonal amplitude from 1961 to 2010 that is punctuated by large decadal and interannual variations. The three pillars of the Green Revolution, consisting of high yield cultivars, fertilizer use, and irrigation, are represented in a terrestrial carbon cycle model. The results reveal that the long-term increase in CO2 seasonal amplitude arises from two major regions in the NH: the mid-latitude cropland between 25N-60N that encompasses the world's major agriculture zones in Asia, Europe and North America, and the high-latitude natural vegetation between 50N-70N that includes much of the Northern boreal forests, tundra and some deciduous forests. The long-term trend of seasonal amplitude is 0.3% per year, of which sensitivity experiments attribute 43% to land use change, 31% to climate variability and change, and 26% to CO2 fertilization. Our results suggest that human

Regulations of new socio-economic formation, the basis of which forms «green» (sustainable economy are studied. The results of the analysis. The following conclusions might be done on the base of the author’s studies. The main properties of green economy are: - sharp decline of ecodestructive processes of production and consumption; this is achieved by the transition to renewable sources of energy and renewable material resources, as well as the abandonment of fossil fuels and combustion processes for energy production; today renewable energy sources, reaching in some countries (Germany, Denmark, Sweden 20-30% of the energy production have practically replaced the nuclear power that allows to displace nuclear energy development program; - computerization of all spheres of economic and social life; one of the directions of this was creation of digital control systems: «smart» manufacturing operations, sites, shops and factories, «smart» cities and communications; «smart» regions and countries; the result is a significant increase in the efficiency of the economic processes implementation; - dematerialization of industrial metabolism of society, i.e. reduction of resource intensity (material and energy consumption of the processes; it is achieved by using 3D-printer, the widespread introduction of additive methods of goods production, miniaturization, increased functionality and convergence of consumer goods (i.e. convergence of their properties; - naturalization of materials and processes, i.e. approximation of

    At the end of the eighteenth century, England and France both underwent revolutions: France the French Revolution, England the industrial revolution. This note sheds new light on these contrasting experiences in the histories of England and France by looking at the evolution of real consumer prices...... to maintain a decent living, and often had to cut consumption to make ends meet. The exercise conducted in the present paper gives a quantitative and economic underpinning to the notion that the French revolution did not arise out of nowhere, but rather had its roots in centuries of hardship amongst working...

    An apparent species-specific relatedness of SIVagm suggests a coevolution with their natural hosts. However, the exact species or subspecies classification of African green monkeys, AGM, is uncertain because current classification schemes rely on phenotype markers, while more definitive genetic...... data are lacking. In this study, the CD4 protein involved in tissue type recognition was gentically cloned and sequence from PBMC RNA from all AGM species, including Barbados green monkeys (BGM). Phylogenetic trees were constructed that also included genomic CD4 nucleotide sequences from patas, sooty...

    Understanding the genetic bases of natural variation for developmental and stress-related traits is a major goal of current plant biology. Variation in plant hormone levels and signaling might underlie such phenotypic variation occurring even within the same species. Here we report the genetic and molecular basis of semidwarf individuals found in natural Arabidopsis thaliana populations. Allelism tests demonstrate that independent loss-of-function mutations at GA locus 5 (GA5), which encodes gibberellin 20-oxidase 1 (GA20ox1) involved in the last steps of gibberellin biosynthesis, are found in different populations from southern, western, and northern Europe; central Asia; and Japan. Sequencing of GA5 identified 21 different loss-of-function alleles causing semidwarfness without any obvious general tradeoff affecting plant performance traits. GA5 shows signatures of purifying selection, whereas GA5 loss-of-function alleles can also exhibit patterns of positive selection in specific populations as shown by Fay and Wu's H statistics. These results suggest that antagonistic pleiotropy might underlie the occurrence of GA5 loss-of-function mutations in nature. Furthermore, because GA5 is the ortholog of rice SD1 and barley Sdw1/Denso green revolution genes, this study illustrates the occurrence of conserved adaptive evolution between wild A.thaliana and domesticated plants.

    After an outbreak of Yersinia enterocolitica at a NHP research facility, we performed a multispecies investigation of the prevalence of Yersinia spp. in various mammals that resided or foraged on the grounds of the facility, to better understand the epizootiology of yersiniosis. Blood samples and fecal and rectal swabs were obtained from 105 captive African green monkeys (AGM), 12 feral cats, 2 dogs, 20 mice, 12 rats, and 3 mongooses. Total DNA extracted from swab suspensions served as template for the detection of Y. enterocolitica DNA by real-time PCR. Neither Y. enterocolitica organisms nor their DNA were detected from any of these samples. However, Western blotting revealed the presence of Yersinia antibodies in plasma. The AGM samples revealed a seroprevalence of 91% for Yersinia spp. and of 61% for Y. enterocolitica specifically. The AGM that were housed in cages where at least one fatality occurred during the outbreak (clinical group) had similar seroprevalence to that of AGM housed in unaffected cages (nonclinical group). However, the nonclinical group was older than the clinical group. In addition, 25%, 100%, 33%, 10%, and 10% of the sampled local cats, dogs, mongooses, rats, and mice, respectively, were seropositive. The high seroprevalence after this outbreak suggests that Y. enterocolitica was transmitted effectively through the captive AGM population and that age was an important risk factor for disease. Knowledge regarding local environmental sources of Y. enterocolitica and the possible role of wildlife in the maintenance of yersiniosis is necessary to prevent and manage this disease.

    Full Text Available While the circumstances surrounding the origin and spread of HIV are becoming clearer, the particulars of the origin of simian immunodeficiency virus (SIV are still unknown. Specifically, the age of SIV, whether it is an ancient or recent infection, has not been resolved. Although many instances of cross-species transmission of SIV have been documented, the similarity between the African green monkey (AGM and SIVagm phylogenies has long been held as suggestive of ancient codivergence between SIVs and their primate hosts. Here, we present well-resolved phylogenies based on full-length AGM mitochondrial genomes and seven previously published SIVagm genomes; these allowed us to perform the first rigorous phylogenetic test to our knowledge of the hypothesis that SIVagm codiverged with the AGMs. Using the Shimodaira-Hasegawa test, we show that the AGM mitochondrial genomes and SIVagm did not evolve along the same topology. Furthermore, we demonstrate that the SIVagm topology can be explained by a pattern of west-to-east transmission of the virus across existing AGM geographic ranges. Using a relaxed molecular clock, we also provide a date for the most recent common ancestor of the AGMs at approximately 3 million years ago. This study substantially weakens the theory of ancient SIV infection followed by codivergence with its primate hosts.

    1992-08-01

    Dietary psyllium's ability to reduce low-density-lipoprotein (LDL) cholesterol is presumably mediated by increased LDL catabolism and/or reduced LDL synthesis. To distinguish between these possibilities, apolipoprotein B (apo B) metabolism was studied in adult male African green monkeys consuming one of three semipurified diets: low-cholesterol cellulose (LCC), high-cholesterol cellulose (HCC), or high-cholesterol psyllium (HCP). 131I-labeled LDL and 125I-labeled VLDL were injected simultaneously into animals; blood samples were drawn at selected times and apo B specific activity determined in VLDL, IDL, and LDL. Based on a multicompartmental model, LDL apo B pool size and de novo apo B transport were elevated significantly in HCC animals compared with HCP and LCC animals. Differences in LDL transport, although not significant, paralleled differences observed in LDL apo B pool size. Fractional catabolic rates were similar among groups (HCC 0.040 +/- 0.010; HCP 0.042 +/- 0.009, and LCC 0.043 +/- 0.004 pools/h). These data suggest that dietary psyllium reduces plasma cholesterol concentrations by decreasing LDL synthesis. PMID:1322033

    1992-08-01

    Psyllium's effects on plasma and lipoprotein cholesterol concentrations, cholesterol metabolism, and diet-induced atherosclerosis were studied in adult male African green monkeys (Cercopithecus aethiops). Animals were fed for 3.5 y one of three experimental diets: low-cholesterol cellulose (LCC), high-cholesterol cellulose (HCC), or high-cholesterol psyllium (HCP). The LCC and HCP groups had significantly (P less than 0.05) lower plasma cholesterol concentrations (39% lower) at 1 mo than did the HCC group. These responses persisted throughout the study. Plasma cholesterol changes were due to a reduction in intermediate-density and low-density lipoproteins; very-low and high-density-lipoprotein concentrations were similar among groups. Aortic atherosclerosis, evaluated as percent sudanophilia at 3.5 y, was lowest in the LCC group, intermediate in the HCP group, and highest in the HCC group. Cholesterol absorption, neutral steroid and fat excretion, HMGCoA reductase activity (in intestine and liver), and body weight were unrelated to psyllium's hypocholesterolemic effects. PMID:1322032

    Intestinal structure of male adult African Green monkeys (Cercopithecus aethiops ssp vervets) was studied after 3 1/2 yr of consuming diets containing 10% psyllium husk or cellulose. Scanning electron microscopy (SEM) identified mild damage (cellular swelling and disarray, and microvillar denudation and disarray) at villous tips throughout the small intestine in the psyllium-fed monkeys. The cellulose group had similar duodenal damage. Differences were not found in colons by SEM. By light microscopy, jejunum had shorter villi with psyllium feeding, based upon villous height (P less than 0.05), and length around a sectioned villus (P less than 0.1), but not based upon the number of enterocytes per villus. Jejunal and ileal circular and longitudinal muscle layer thicknesses were increased in psyllium-fed monkeys. Colonic mucosal height was significantly (P less than 0.05) reduced and muscle layer thickness was mildly reduced in the psyllium-fed monkeys. Group differences were not found in intestinal weight or length or in the weight of small intestinal mucosal scrapings. Psyllium husk may cause epithelial cell loss and muscle layer hypertrophy in the jejunum and ileum and thinning of the colonic wall after prolonged feeding. PMID:3031252

  11. Plasmid-Chromosome Recombination of Irradiated Shuttle Vector DNA in African Green Monkey Kidney Cells.

    Mudgett, John Stuart

    1987-09-01

    An autonomously replicating shuttle vector was used to investigate the enhancement of plasmid-chromosome recombination in mammalian host cells by ultraviolet light and gamma radiation. Sequences homologous to the shuttle vector were stably inserted into the genome of African Green Monkey kidney cells to act as the target substrate for these recombination events. The SV40- and pBR322-derived plasmid DNA was irradiated with various doses of radiation before transfection into the transformed mammalian host cells. The successful homologous transfer of the bacterial ampicillin resistance (amp^{rm r}) gene from the inserted sequences to replace a mutant amp^->=ne on the shuttle vector was identified by plasmid extraction and transformation into E. coli host cells. Ultraviolet light (UV) was found not to induce homologous plasmid-chromosome recombination, while gamma radiation increased the frequency of recombinant plasmids detected. The introduction of specific double -strand breaks in the plasmid or prolonging the time of plasmid residence in the mammalian host cells also enhanced plasmid-chromosome recombination. In contrast, plasmid mutagenesis was found to be increased by plasmid UV irradiation, but not to change with time. Plasmid survival, recombination, and mutagenesis were not affected by treating the mammalian host cells with UV light prior to plasmid transfection. The amp^{rm r} recombinant plasmid molecules analyzed were found to be mostly the result of nonconservative exchanges which appeared to involve both homologous and possibly nonhomologous interactions with the host chromosome. The observation that these recombinant structures were obtained from all of the plasmid alterations investigated suggests a common mechanistic origin for plasmid -chromosome recombination in these mammalian cells.

    Full Text Available Filoviruses are members of the genera Ebolavirus, Marburgvirus, and “Cuevavirus”. Because they cause human disease with high lethality and could potentially be used as a bioweapon, these viruses are classified as CDC Category A Bioterrorism Agents. Filoviruses are relatively stable in aerosols, retain virulence after lyophilization, and can be present on contaminated surfaces for extended periods of time. This study explores the characteristics of aerosolized Sudan virus (SUDV Boniface in non-human primates (NHP belonging to three different species. Groups of cynomolgus macaques (cyno, rhesus macaques (rhesus, and African green monkeys (AGM were challenged with target doses of 50 or 500 plaque-forming units (pfu of aerosolized SUDV. Exposure to either viral dose resulted in increased body temperatures in all three NHP species beginning on days 4–5 post-exposure. Other clinical findings for all three NHP species included leukocytosis, thrombocytopenia, anorexia, dehydration, and lymphadenopathy. Disease in all of the NHPs was severe beginning on day 6 post-exposure, and all animals except one surviving rhesus macaque were euthanized by day 14. Serum alanine transaminase (ALT and aspartate transaminase (AST concentrations were elevated during the course of disease in all three species; however, AGMs had significantly higher ALT and AST concentrations than cynos and rhesus. While all three species had detectable viral load by days 3-4 post exposure, Rhesus had lower average peak viral load than cynos or AGMs. Overall, the results indicate that the disease course after exposure to aerosolized SUDV is similar for all three species of NHP.

    Niacin is the most effective drug available for raising levels of high-density lipoprotein (HDL) cholesterol. To evaluate its effects on plasma lipid concentrations, the authors administered a low dose of niacin to healthy, adult, female African green monkeys for 3 months. In the treated monkeys, low-density lipoprotein cholesterol concentrations decreased by 43% from baseline, whereas concentrations of HDL cholesterol and apolipoprotein A-I increased by 49% and 34%, respectively. The results suggest that in this primate model, a low dose of niacin can effectively increase concentrations of HDL cholesterol.©2014 Nature America, Inc. All rights reserved.

    The nucleotide sequence and enhancer activity of the long terminal repeats (LTRs) associated with a cloned endogenous African green monkey (AGM) retroviral DNA designated as lambda-AGM-1 was studied. A unique feature of the endogenous AGM proviral LTRs was the presence of multiple copies of two types of directly repeating units in the U3 region: 16 8-base-pair (bp) repeats were present in the 5' LTR and 12 were present in the 3' LTR which were bound by a 6-bp perfect direct repeat; tandem dup...

  17. Remedial Measures for Counterbalancing the After Effects of Green Revolution on the Georesources of Groundwater, Land and Soil in Haryana, India

    2008-05-01

    In Haryana, one of the wheat granaries of India where water resources have depleted to a critical level (1050 m3 /year/person), groundwater alone has 53% share in the irrigation, the remaining 47% comes from canal system of glacier-fed rivers, viz., Yamuna and Satluj originating from Himalayas. The Green Revolution (1971-1990, intensive phase) enabled this small state to become an agro-economic state in northern alluvial plains of India. Though occupying 1.3 % geographical area and containing 2% of the population of India, it produces country's 13% wheat and about 3% quality rice besides other cereals, oil seeds, sugarcane and cotton. However, Haryana paid a heavy price for the impressive agricultural development- one-third of the irrigated land is salinity affected, water level declined by 3-12 m in twelve of its nineteen districts and excessive nitrate levels in the groundwater (114-1800 mg/l) have rendered the groundwater non-potable in many areas. Groundwater in the arid western Haryana is mostly saline (TDS > 4000 mg/l) and irrational canal irrigation has paradoxically raised the water-table by 3-9m in seven districts causing waterlogging over 2346 km2 land of which 251 km2 is fully waterlogged. In the land use pattern 131,000 ha prime cultivable land (about 3% of the total) has been lost to urbanization jeopardizing the FOOD SECURITY. One possible way to arrest the degradation of groundwater and soil, is to switch to dryland farming. This would involve change in the irrigation method as well as proper selection and rotation of food crops like barley, sorghum, maize, different types of beans (pulses) and oil seeds like groundnut, sunflower, mustard, etc. and restricted use of chemical fertilizers and pesticides. Dryland farming could go hand in hand with the plantation of fruit trees, grasses and medicinal plants suitable to this agro-climatic zone, and animal husbandry. The same considerations also hold good to the adjoining eastern Rajasthan.

    2015-09-01

    Here, we show a mechanism for expansion regulation through mutations in the green revolution gene gibberellin20 (GA20)-oxidase and show that GAs control biosynthesis of the plants main structural polymer cellulose. Within a 12,000 mutagenized Sorghum bicolor plant population, we identified a single cellulose-deficient and male gametophyte-dysfunctional mutant named dwarf1-1 (dwf1-1). Through the Sorghum propinquum male/dwf1-1 female F2 population, we mapped dwf1-1 to a frameshift in GA20-oxidase. Assessment of GAs in dwf1-1 revealed ablation of GA. GA ablation was antagonistic to the expression of three specific cellulose synthase genes resulting in cellulose deficiency and growth dwarfism, which were complemented by exogenous bioactive gibberellic acid application. Using quantitative polymerase chain reaction, we found that GA was positively regulating the expression of a subset of specific cellulose synthase genes. To cross reference data from our mapped Sorghum sp. allele with another monocotyledonous plant, a series of rice (Oryza sativa) mutants involved in GA biosynthesis and signaling were isolated, and these too displayed cellulose deficit. Taken together, data support a model whereby suppressed expansion in green revolution GA genes involves regulation of cellulose biosynthesis. PMID:26198258

    Green technology is a kind of eco-friendly technology shaped in the process of abandoning modern technology ; Provoked by green ide- a in green movement, green technology has three parts of its theoretical foundation: System Ecology; Theory of Marxism and Gala Hypothesis. Besides, green technology aslo tries to make three practical revolutions: they are from "production supreme" to "eco- rationality", from "unlim- ited growth" to "limited development", from "price goes first" to "multiple value centralization". In every turning of green technology, it shows an important idea that human, economy and environment should be a synchronized development.%绿色技术是在对现代技术进行批判扬弃的基础上形成的环境友好型技术,它是绿色观念实践的产物。在理论上,绿色技术的理论支撑主要由系统生态学、马克思主义理论和盖娅假说三个部分组成;在实践中,绿色技术主要实现了从"生产合理性"到"生态合理性",从"增长无极限"到"发展有极限",从"价格导向"到"价值导向"三个方面的实践转向。在每一个转向中,都体现了绿色技术努力践行"人—环境"的双重利益诉求。

However, those who live in the capital still worry whether it will be possible to turn the rather polluted city. into a green or even half-green city. But time and again, China has proved that this kind of huge challenge can be met. Nevertheless,this time around it is a tough call indeed and a little over three years are left to execute and complete an audacious task.

    中国现代革命的发展历程可以明显分为3个阶段:第1阶段是"红色革命",从1921年中国共产党成立到1949年中华人民共和国成立;第2阶段是以发展工业革命为代表的"黑色革命",从1949年新中国成立开始到2000年中国基本进入小康初级阶段;第3阶段是2000~2010年建设资源节约型和环境友好型社会的"绿色革命".中国在不到100年内实现了从"红色革命"到"黑色革命"再到"绿色革命"的三大跨越.中国未来必须走以清洁能源和再生能源、绿色制造和绿色农业为主的低碳经济发展的"绿色革命"之路,才能保障生态环境改善和食品安全并可持续发展.%The history of Chinese modern revolution can be grouped into three periods as follows: the red revolution period (from the founding of the Chinese Communist Party in 1921 to that of the People's Republic of China in 1949), the black revolution period (from start of industrial revolution in 1949 to the initial stage of a well-off society in 2000), and the green revolution period (from 2000 to 2010 aimed at developing a resource-saving and environment-friendly society). China has therefore accomplished a tri-giant leap from the red revolution to the black revolution, and then to the green revolution in the space of just one century. In the future,China must embark on green revolution, develop clean and renewable energy, green manufacturing and agricultural production, and low carbon economy. These measures would not only reduce pollution, but also improve the environment, ensure food safety and sustainable development in the country.

    The turn of the XXth century witnessed a revolution in physics comparable to Isaac Newton’s discovery of the universal laws of mechanics and of gravitation three centuries earlier. The world required to be described in novel terms, as the immutable, deterministic view of our familiar universe had given way to a new world picture, one which featured chance, flux, and an incessant upsurge of waves of matter. Such a worldview was so radically new and counterintuitive that it gave rise to strong debates, to the effect that Albert Einstein himself tried to oppose it on the grounds that “God does not play dice”. In spite of the intense debates that accompanied its emergence, quantum mechanics quickly proved an incredibly efficacious new tool to understand and to predict a wide array of new phenomena. It was so successful that in no time it broke free from the environment of research labs to become part of daily life, making it possible, for example, to understand why some materials...

    The purpose of this work was to detect the properties of African green monkey renal epithelial cells (Vero) after oxidative injury and to study the mediation of the injured Vero on aggregation and formation of calcium oxalate crystals. This injury model was induced by 0.15 mmol/L H2O2 according to the pretest evaluation. The results suggested that H2O2 could injure Vero significantly and decrease cell viability in a time-dependent manner for exposure time of 0.5--2 h. After cell injury, the indexes connected with oxidative injury changed. The malondialdehyde (MDA) content and osteopontin (OPN) expression increased, while superoxide dismutase (SOD) level decreased. It resulted in the increase of both the amount of CaOxa crystals and the degree of crystal aggregation on the injured cells. This work indicated that injured cells promoted the formation of calcium oxalate monohydrate (COM) crystals, thus increased the risk of formation of urinary stone.

  11. Exploring the challenges associated with the greening of supply chains in the South African manganese and phosphate mining industry

    2014-03-01

    Full Text Available As with most mining activities, the mining of manganese and phosphate has serious consequences for the environment. Despite a largely adequate and progressive framework for environmental governance developed since 1994, few mines have integrated systems into their supply chain processes to minimise environmental risks and ensure the achievement of acceptable standards. Indeed, few mines have been able to implement green supply chain management (GrSCM. The purpose of this article was to explore challenges related to the implementation of GrSCM and to provide insight into how GrSCM can be implemented in the South African manganese and phosphate industry. This article reported findings of a qualitative study involving interviews with 12 participants from the manganese and phosphate industry in South Africa. Purposive sampling techniques were used. Emerging from the study were six themes, all of which were identified as key challenges in the implementation of GrSCM in the manganese and phosphate mining industry. From the findings, these challenges include the operationalisation of environmental issues, lack of collaboration and knowledge sharing, proper application of monitoring and control systems,lack of clear policy and legislative direction, the cost of implementing GrSCM practices, and the need for strong leadership and management of change. On the basis of the literature reviewed and empirical findings, conclusions were drawn and policy and management recommendations were accordingly made.

    African green monkeys (AGMs) are natural primate hosts of simian immunodeficiency virus (SIV). Interestingly, features of the envelope-specific antibody responses in SIV-infected AGMs are distinct from that of HIV-infected humans and SIV-infected rhesus monkeys, including gp120-focused responses and rapid development of autologous neutralization. Yet, the lack of genetic tools to evaluate B-cell lineages hinders potential use of this unique non-human primate model for HIV vaccine development. Here we define features of the AGM Ig loci and compare the proportion of Env-specific memory B-cell populations to that of HIV-infected humans and SIV-infected rhesus monkeys. AGMs appear to have a higher proportion of Env-specific memory B cells that are mainly gp120 directed. Furthermore, AGM gp120-specific monoclonal antibodies display robust antibody-dependent cellular cytotoxicity and CD4-dependent virion capture activity. Our results support the use of AGMs to model induction of functional gp120-specific antibodies by HIV vaccine strategies. PMID:27381634

    Full Text Available Human immunodeficiency virus type 1 (HIV-1 Vif is essential for viral evasion of the host antiviral protein APOBEC3G (APO3G. The Vif protein from a distantly related African green monkey (Agm simian immunodeficiency virus (SIVagm is unable to suppress the antiviral activity of human APO3G but is active against Agm APO3G. SIVmac Vif on the other hand, possesses antiviral activity against both human and Agm APO3G. In this study, we were interested in mapping domains in SIVmac Vif that are responsible for its dual activity against human and Agm APO3G. We constructed a series of Vif chimeras by swapping domains in SIVmac Vif with equivalent regions from SIVagm Vif and determined their activity against human and Agm APO3G. We found that replacing any region in SIVmac Vif by corresponding fragments from SIVagm Vif only moderately reduced the activity of the chimeras against Agm APO3G but in all cases resulted in a severe loss of activity against human APO3G. These results suggest that the domains in SIVmac Vif required for targeting human and Agm APO3G are distinct and cannot be defined as linear amino acid motifs but rather appear to depend on the overall structure of full-length SIVmac Vif.

  14. Organisation of nucleosomal arrays reconstituted with repetitive African green monkey α-satellite DNA as analysed by atomic force microscopy

    2007-01-01

    Alpha-satellite DNA (AS) is part of centromeric DNA and could be relevant for centromeric chromatin structure: its repetitive character may generate a specifically ordered nucleosomal arrangement and thereby facilitate kinetochore protein binding and chromatin condensation. Although nucleosomal positioning on some satellite sequences had been shown, including AS from African green monkey (AGM), the sequence-dependent nucleosomal organisation of repetitive AS of this species has so far not been analysed. We therefore studied the positioning of reconstituted nucleosomes on AGM AS tandemly repeated DNA. Enzymatic analysis of nucleosome arrays formed on an AS heptamer as well as the localisation of mononucleosomes on an AS dimer by atomic force microscopy (AFM) showed one major positioning frame, in agreement with earlier results. The occupancy of this site was in the range of 45–50%, in quite good agreement with published in vivo observations. AFM measurements of internucleosomal distances formed on the heptamer indicated that the nucleosomal arrangement is governed by sequence-specific DNA-histone interactions yielding defined internucleosomal distances, which, nevertheless, are not compatible with a uniform phasing of the nucleosomes with the AGM AS repeats.

    Full Text Available Morphometric variation of Pelophylax saharicus was analysed using univariate and multivariate statistics, with both traditional and geometric morphometrics, based on 148 specimens from four different geographical localities in Tunisia and Algeria. The results show the existence of three morphotypes in Tunisia and one in Algeria, and indicate a significant degree of variation in morphometric characters between regions. Specimens from the southernmost region have the smallest body size and the greatest morphometric divergence from other populations. This pattern of morphometric variation probably results from phenotypic plasticity in response to local environmental factors. The results of our chromosomal study (C-, Ag-NOR-, endonuclease digestion, DAPI, CMA3 and Q-banding reveal this species to exhibit the plesiomorphic Pelophylax karyotype of 2n = 26 biarmed chromosomes and NORs on the eleventh pair. Similarities and differences of the North African green frog are discussed in relation to the different forms of data collected (chromosomal, morphometric, ecological [Current Zoology 56 (6: 678–686, 2010].

Previous paleontological and scarce molecular data suggest possible faunal exchange later than the well-documented landbridge in the Messinian (5.3 My; however, a possible African origin of recent terrestrial Sicilian fauna has not been thoroughly tested with molecular methods. To gain insight into the phylogeography of the region, we examine two mitochondrial and two nuclear markers (one is a newly adapted intron marker in green toads (Bufo viridis subgroup across that sea barrier, the Strait of Sicily. Results Extensive sampling throughout the western Mediterranean and North Africa revealed a deep sister relationship between Sicilian (Bufo siculus n.sp. and African green toads (B. boulengeri on the mitochondrial and nuclear level.

  4. Visualization of the African swine fever virus infection in living cells by incorporation into the virus particle of green fluorescent protein-p54 membrane protein chimera

    International Nuclear Information System (INIS)

    Many stages of African swine fever virus infection have not yet been studied in detail. To track the behavior of African swine fever virus (ASFV) in the infected cells in real time, we produced an infectious recombinant ASFV (B54GFP-2) that expresses and incorporates into the virus particle a chimera of the p54 envelope protein fused to the enhanced green fluorescent protein (EGFP). The incorporation of the fusion protein into the virus particle was confirmed immunologically and it was determined that p54-EGFP was fully functional by confirmation that the recombinant virus made normal-sized plaques and presented similar growth curves to the wild-type virus. The tagged virus was visualized as individual fluorescent particles during the first stages of infection and allowed to visualize the infection progression in living cells through the viral life cycle by confocal microscopy. In this work, diverse potential applications of B54GFP-2 to study different aspects of ASFV infection are shown. By using this recombinant virus it was possible to determine the trajectory and speed of intracellular virus movement. Additionally, we have been able to visualize for first time the ASFV factory formation dynamics and the cytophatic effect of the virus in live infected cells. Finally, we have analyzed virus progression along the infection cycle and infected cell death as time-lapse animations

    I respond to the critical comments by Martin Kusch and Ursula Klein on my account of the Chemical Revolution. I comment along three different lines: descriptive, explanatory, and normative. (1) I agree with Klein that Lavoisier did not introduce drastic changes in chemical ontology, but maintain that there was methodological incommensurability in the Chemical Revolution; in response to Kusch's view, I maintain that Lavoisier's victory was slow and incomplete. (2) Admitting that there were many causes shaping the outcome of the Chemical Revolution, including the convenience of Lavoisier's theoretical scheme and various complicated social factors, I still think that the general rise of compositionism was an important factor. (3) I defend my normative pluralist view on the Chemical Revolution, denying Kusch's argument that chemists had overwhelmingly good reasons to trust Lavoisier and his allies over the phlogistonists. Overall, I agree with Kusch that it would be desirable to have a good descriptive-normative sociological account of the Chemical Revolution, but I also think that it should be an account that allows for divergence in individuals' and sub-communities' self-determination.

    The detection of nuclear or radioactive materials for homeland or national security purposes is inherently difficult. This is one reason detection efforts must be seen as just one part of an overall nuclear defense strategy which includes, inter alia, material security, detection, interdiction, consequence management and recovery. Nevertheless, one could argue that there has been a revolution in detection affairs in the past several decades as the innovative application of new technology has changed the character and conduct of detection operations. This revolution will likely be most effectively reinforced in the coming decades with the networking of detectors and innovative application of anomaly detection algorithms.

They are consumed in both rural and urban areas in those places as a main food, food ingredient or traditional medicine. Currently, there is limited information about their nutritional and phytochemical composition. Therefore, mineral, vitamin C, phenolic and flavonoid concentration, and antioxidant activity were evaluated in multiple accessions of these leafy vegetables, and their mineral and vitamin C contribution per serving was calculated. The concentrations of Ca, K, Mg and P in these leafy vegetables were 0.82-2.32, 1.61-7.29, 0.61-1.48 and 0.27-1.44 mg/g fresh weight (FW), respectively. The flavonoid concentration in S. scabrum accessions was up to 1413 μg catechin equivalents/g FW, while the highest antioxidant activities were obtained in C. longirostrata accessions (52-60 μmol Trolox equivalents/g FW). According to guidelines established by the US Food and Drug Administration, a serving size (30 g FW) of C. longirostrata would be considered an excellent source of Mo (20 % or more of the daily value), and a serving of any of these green leafy vegetables would be an excellent source of vitamin C. Considering the importance of the minerals, phytochemicals and antioxidants in human health and their presence in these indigenous green leafy vegetables, efforts to promote their consumption should be implemented.

    Africa's smallholder agricultural systems face unique challenges in planning for reducing poverty, concurrent with adaptation and mitigation to climate change. At continental level, policy seeks to promote a uniquely African Green Revolution to increase crop yields and food production, and improve local livelihoods. However, the consequences on the environment and climate are not clear; these pro-economic development measures should be linked to climate change adaptation and mitigation measures, and research is required to help achieve these policy proposals by identifying options, and testing impacts. In particular, increased nitrogen (N) inputs are essential for increasing food production in Africa, but are accompanied by inevitable increases in losses to the environment. These losses appear to be low at input levels promoted in agricultural development programs, while the increased N inputs both increase current food production and appear to reduce the vulnerability of food production to changes in climate. We present field and remote sensing evidence from Malawi that subsidizing improved seed and fertilizers increases resilience to drought without adding excess N to the environment. In Kenya, field research identified thresholds in N2O losses, where emissions are very low at fertilization rates of less than 200 kg ha-1. Village-scale models have identified potential inefficiencies in the food production process where the largest losses of reactive N occur, and which could be targeted to reduce the amount of N released to the environment. We further review some on-going research activities and progress in Africa that compare different methods of managing resources that target resilience in food production and adaptation to climate change, using nutrient N as an indicator, while evaluating the effects of these resource management practices on ecosystems and the environment.

    Clinical decisions and experimental analyses often involve the assessment of hematology and clinical chemistry. Using clinical pathology to assess the health status of NHP in breeding colonies or data from studies than involve pregnancy can often be complicated by pregnancy status. This study had 2 objectives regarding the hematology and clinical chemistry of African green monkeys (AGM, Chlorocebus aethiops sabaeus): 1) to compare pregnant or recently postpartum animals with nonpregnant, nonlactating animals and 2) to create age- and sex-specific reference intervals. Subjects in this study were 491 AGM from the Vervet Research Colony of the Wake Forest University Primate Center. Results indicated that changes in BUN, serum total protein, albumin, ALP, GGT, calcium, phosphorus, sodium, potassium, cholesterol, total CO2, globulins, lipase, amylase, WBC, neutrophils, lymphocytes, platelets, RBC, Hgb, and Hct occur during pregnancy and the postpartum period. Age- and sex-specific reference intervals consistent with guidelines from the American Society for Veterinary Clinical Pathology were established and further expand the understanding of how to define health in AGM on the basis of clinical pathology. The combination of understanding the changes that occur in pregnancy and postpartum and expansive reference intervals will help guide clinical and experimental decisions.

  1. Inhibition of adaptive immune responses leads to a fatal clinical outcome in SIV-infected pigtailed macaques but not vervet African green monkeys.

    Full Text Available African green monkeys (AGM and other natural hosts for simian immunodeficiency virus (SIV do not develop an AIDS-like disease following SIV infection. To evaluate differences in the role of SIV-specific adaptive immune responses between natural and nonnatural hosts, we used SIV(agmVer90 to infect vervet AGM and pigtailed macaques (PTM. This infection results in robust viral replication in both vervet AGM and pigtailed macaques (PTM but only induces AIDS in the latter species. We delayed the development of adaptive immune responses through combined administration of anti-CD8 and anti-CD20 lymphocyte-depleting antibodies during primary infection of PTM (n = 4 and AGM (n = 4, and compared these animals to historical controls infected with the same virus. Lymphocyte depletion resulted in a 1-log increase in primary viremia and a 4-log increase in post-acute viremia in PTM. Three of the four PTM had to be euthanized within 6 weeks of inoculation due to massive CMV reactivation and disease. In contrast, all four lymphocyte-depleted AGM remained healthy. The lymphocyte-depleted AGM showed only a trend toward a prolongation in peak viremia but the groups were indistinguishable during chronic infection. These data show that adaptive immune responses are critical for controlling disease progression in pathogenic SIV infection in PTM. However, the maintenance of a disease-free course of SIV infection in AGM likely depends on a number of mechanisms including non-adaptive immune mechanisms.

    Green algae of the genus Klebsormidium (Klebsormidiales, Streptophyta) are typical members of biological soil crusts (BSCs) worldwide. The phylogeny and ecophysiology of Klebsormidium has been intensively studied in recent years, and a new lineage called superclade G, which was isolated from BSCs in arid southern Africa and comprising undescribed species, was reported. Three different African strains, that have previously been isolated from hot-desert BSCs and molecular-taxonomically characterized, were comparatively investigated. In addition, Klebsormidium subtilissimum from a cold-desert habitat (Alaska, USA, superclade E) was included in the study as well. Photosynthetic performance was measured under different controlled abiotic conditions, including dehydration and rehydration, as well as under a light and temperature gradient. All Klebsormidium strains exhibited optimum photosynthetic oxygen production at low photon fluence rates, but with no indication of photoinhibition under high light conditions pointing to flexible acclimation mechanisms of the photosynthetic apparatus. Respiration under lower temperatures was generally much less effective than photosynthesis, while the opposite was true for higher temperatures. The Klebsormidium strains tested showed a decrease and inhibition of the effective quantum yield during desiccation, however with different kinetics. While the single celled and small filamentous strains exhibited relatively fast inhibition, the uniserate filament forming isolates desiccated slower. Except one, all other strains fully recovered effective quantum yield after rehydration. The presented data provide an explanation for the regular occurrence of Klebsormidium strains or species in hot and cold deserts, which are characterized by low water availability and other stressful conditions.

    Full Text Available The strategy described in the present paper offers details about the possibility for Brazil to play a more substantial role in the gene revolution. If successfully applied, the powerful science-based technology currently available in Brazil can contribute to extend the benefits of the gene revolution to the poorest countries, very much like the Green Revolution did in the past, thereby reducing the hunger syndrome which claimed the lives of millions of people in some Asian countries, particularly Pakistan and India, decades ago. In his visit to Brazil in February 2004, Norman Borlaug had the opportunity to witness the success of Brazilian agriculture. At a Conference held at ESALQ - Superior School of Agriculture Luiz de Queiroz in Piracicaba, SP, Brazil, he stated that the 21st century revolution will come from Brazil in the area of agriculture. He also said that reducing hunger is essential for the world to achieve socioeconomic stability. A central question remains unanswered: who will fund this revolution? The FAO 2003-2004 Annual Report listed the barriers preventing the gene revolution from reaching the poorest countries: inadequate regulatory procedures - Intellectual Property Rights and Biosafety, poorly functioning seed delivering systems and weak domestic plant breeding capacity; all are discussed in this paper.

  4. Frequent substitution polymorphisms in African green monkey CCR5 cluster at critical sites for infections by simian immunodeficiency virus SIVagm, implying ancient virus-host coevolution.

    In contrast to humans, several primate species are believed to have harbored simian immunodeficiency viruses (SIVs) since ancient times. In particular, the geographically dispersed species of African green monkeys (AGMs) are all infected with highly diversified SIVagm viruses at high prevalences (greater than 50% of sexually mature individuals) without evident diseases, implying that the progenitor monkeys were infected prior to their dispersal. If this is correct, AGMs would be expected to have accumulated frequent resistance-conferring polymorphisms in host genes that are important for SIV replication. Accordingly, we analyzed the coding sequences of the CCR5 coreceptors from 26 AGMs (52 alleles) in distinct populations of the four species. These samples contained 29 nonsynonymous coding changes and only 15 synonymous nucleotide substitutions, implying intense functional selection. Moreover, 24 of the resulting amino acid substitutions were tightly clustered in the CCR5 amino terminus (D13N in the vervets and Y14N in the tantalus species) or in the first extracellular loop (Q93R and Q93K in all species). The Y14N substitution was extremely frequent in the 12 wild-born African tantalus, with 7 monkeys being homozygous for this substitution and 4 being heterozygous. Although two of these heterozygotes and the only wild-type homozygote were naturally infected with SIVagm, none of the Y14N homozygotes were naturally infected. A focal infectivity assay for SIVagm indicated that all five tested SIVagms efficiently use CCR5 as a coreceptor and that they also use CXCR6 (STRL33/Bonzo) and GPR15 (BOB) with lower efficiencies but not CXCR4. Interestingly, the D13N, Y14N, Q93R, and Q93K substitutions in AGM CCR5 all strongly inhibited infections by the SIVagm isolates in vitro. The Y14N substitution eliminates a tyrosine sulfation site that is important for infections and results in partial N-linked glycosylation (i.e., 60% efficiency) at this position. Nevertheless, the CCR

  5. Strategy as revolution.

    Hamel, G

    How often does the strategic-planning process start with senior executives asking what the rest of the organization can teach them about the future? Not often enough, argues Gary Hamel. In many companies, strategy making is an elitist procedure and ¿strategy¿ consists of nothing more than following the industry's rules. But more and more companies, intent on overturning the industrial order, are rewriting those rules. What can industry incumbents do? Either surrender the future to revolutionary challengers or revolutionize the way their companies create strategy. What is needed is not a tweak to the traditional strategic-planning process, Hamel says, but a new philosophical foundation: strategy is revolution. Hamel offers ten principles to help a company think about the challenge of creating truly revolutionary strategies. Perhaps the most fundamental principle is that so-called strategic planning doesn't produce true strategic innovation. The traditional planning process is little more than a rote procedure in which deeply held assumptions and industry conventions are reinforced rather than challenged. Such a process harnesses only a tiny proportion of an organization's creative potential. If there is to be any hope of industry revolution, senior managers must give up their monopoly on the creation of strategy. They must embrace a truly democratic process that can give voice to the revolutionaries that exist in every company. If senior managers are unwilling to do this, employees must become strategy activists. The opportunities for industry revolution are mostly unexplored. One thing is certain: if you don't let the revolutionaries challenge you from within, they will eventually challenge you from without--in the marketplace. PMID:10158475

    2009-01-01

    Louis Pasteur (1822-1895) is considered the most notable medical scientist of his time and perhaps one of the most distinguished of all times in the history of medicine. From Dole in France to Paris, from a student of crystals to "living ferments," and from chemistry to biology and medicine, Pasteur changed the world for the benefit of humanity. The genius of Pasteur dealt with the most pressing issues of his time, basing the germ theory on the effects that microorganisms had on fermentation and putrefaction of organic matter, which gave birth to the science of bacteriology. Many other difficult problems in medicine and biology were tackled by Pasteur, culminating in the spectacular results seen with the treatment of rabies. Surgery was no exception to the scientific conquests of Pasteur. The transformation of the surgical world arose from the antiseptic concepts of Lister that were based on the germ theory of the disease, which had been derived from the germ theory of fermentation and putrefaction discovered by Pasteur. The acceptance of these principles represented the surgical revolution brought on by the science of Pasteur, a revolution that is now accepted in our daily care of surgical patients.

    2007-03-01

    Modern contraceptive technology is more than a technical advance: it has brought about a true social revolution, the 'first reproductive revolution' in the history of mankind. This latter was followed in rapid succession by other major changes in human reproductive strategies. In the human species, sexual activity began to lose its exclusive reproductive meaning at an early stage of its evolution. Human beings must have practiced non-conceptive sex from the outset and therefore must have had a need to avoid, rather than to seek conception during intercourse from time immemorial. The search for methods to control fertility went on for millennia, but a valid solution was only found during the twentieth century, when the population explosion had forever changed the shape of humanity: in only one century the total population of the planet had grown from some 1.6 billion to more than 6 billion. That increase will remain unique in the history of Homo sapiens. At the global level, contraception provided a tool to deal with overpopulation and, in only 50 years, went a long way towards its resolution. However, to solve the problem, national and international family planning initiatives were required. For individuals, contraception also meant a revolution. It allowed sexual intercourse without reproduction. Only 25 years later, in vitro fertilisation permitted childbearing without sexual intercourse. Other advances followed and now cloning, that is, reproduction without the two gametes, looms on the horizon. Such a series of rapid, major changes in human reproductive strategies has confused many. For this reason, a constructive dialogue between sociology and biology is mandatory. Contraception is a powerful tool to promote equity between sexes; it improves women's status in the family and in the community. Avoiding pregnancy during the teens increases opportunities for a young woman's education, training and employment. By controlling their fertility, women get a chance to

  13. Scrutinizing the epigenetics revolution.

    Meloni, Maurizio; Testa, Giuseppe

    2014-11-01

    Epigenetics is one of the most rapidly expanding fields in the life sciences. Its rise is frequently framed as a revolutionary turn that heralds a new epoch both for gene-based epistemology and for the wider discourse on life that pervades knowledge-intensive societies of the molecular age. The fundamentals of this revolution remain however to be scrutinized, and indeed the very contours of what counts as 'epigenetic' are often blurred. This is reflected also in the mounting discourse on the societal implications of epigenetics, in which vast expectations coexist with significant uncertainty about what aspects of this science are most relevant for politics or policy alike. This is therefore a suitable time to reflect on the directions that social theory could most productively take in the scrutiny of this revolution. Here we take this opportunity in both its scholarly and normative dimension, that is, proposing a roadmap for social theorizing on epigenetics that does not shy away from, and indeed hopefully guides, the framing of its most socially relevant outputs. To this end, we start with an epistemological reappraisal of epigenetic discourse that valorizes the blurring of meanings as a critical asset for the field and privileged analytical entry point. We then propose three paths of investigation. The first looks at the structuring elements of controversies and visions around epigenetics. The second probes the mutual constitution between the epigenetic reordering of living phenomena and the normative settlements that orient individual and collective responsibilities. The third highlights the material import of epigenetics and the molecularization of culture that it mediates. We suggest that these complementary strands provide both an epistemically and socially self-reflective framework to advance the study of epigenetics as a molecular juncture between nature and nurture and thus as the new critical frontier in the social studies of the life sciences.

    Full Text Available This article addresses the materialist theory of development and fall of Marxism based on the theory of value as originally considered and presented by Karl Marx in Grundrisse and in Crítica da Economia Política, claiming that the production of value depends on labor force. As it takes place today, capital displaces labor force in every industry, service and activity, country, territory and region all over the world; workers are dismissed and are transferred to speculative activities of the fictional capital. This lesser disposition of labor force eventually harms the mean profit rate and, as time goes by, it provokes a crisis. The present capitalist crisis is resultant from the insufficiency and, to certain extent, to the incapacity of mechanisms from the system to generate enough value production in the labor process, to provide value to the invested capital (in settings of production, raw matter, and in labor force or variable capital; to create more value and to regain increased profit rate. These restraints of the financial capital (fictional capital cause a deviation to the speculative plan and contribute for the formation of tragic speculative bubbles in sectors such as those of housing, energy and food. No matter how much productivity is increased, developing a technological revolution and “sparing labor force”, the reduction of time, socially required for the production of goods and labor force, becomes harder and more marginal. This is the way the capitalist system enters a civilian, structural and organic crisis, as it is now. To go beyond the capital means to construct structures and superstructures of a new non-capitalist society based on a new way to produce, to work and to keep harmonious and friendly human social relations. It is difficult to have a successful revolution if not with the education of its agents, that is, the organized front people, parties and syndicates that will raise the social, political and cultural

    The Earth that sustains us today was born out of a few remarkable, near-catastrophic revolutions, started by biological innovations and marked by global environmental consequences. The revolutions have certain features in common, such as an increase in the complexity, energy utilization, and information processing capabilities of life. This book describes these revolutions, showing the fundamental interdependence of the evolution of life and its non-living environment. We would not exist unless these upheavals had led eventually to 'successful' outcomes - meaning that after each one, at length, a new stable world emerged. The current planet-reshaping activities of our species may be the start of another great Earth system revolution, but there is no guarantee that this one will be successful. This book explains what a successful transition through it might look like, if we are wise enough to steer such a course.

Richard Trudeau confronts the fundamental question of truth and its representation through mathematical models in The Non-Euclidean Revolution. First, the author analyzes geometry in its historical and philosophical setting; second, he examines a revolution every bit as significant as the Copernican revolution in astronomy and the Darwinian revolution in biology; third, on the most speculative level, he questions the possibility of absolute knowledge of the world. Trudeau writes in a lively, entertaining, and highly accessible style. His book provides one of the most stimulating and personal presentations of a struggle with the nature of truth in mathematics and the physical world.

    Since the revolution and the overthrow of the Gang of Four, China has embarked upon a program of modernization, internationalization, and technological development. The sloganeering campaign for general health as espoused by Chairman Mao is as follows: 1) prevention, including immunizations and early illness detection; 2) serve the workers, peasants, and soldiers; 3) medical work integrated into all other modernization efforts; and 4) combine traditional and Western medicine. The mass campaign aims to involve individuals in improving their health care facilities at the same time they are involved in production of goods and services. Rural workers are mobilized in mass cleanup and prevention campaigns. Of the 8.7 million health workers, nearly 2 million are barefoot doctors, or other types of doctors serving at the lowest rung of paramedical service. Basic services are widely available. Costs are low, access is easy. For about 95% of illnesses the system works very well. Patients with illnesses requiring high technology care, e.g., organ transplant, cannot survive. Chairman Mao codified traditional medicine as a curriculum component for education; it is based on ancient West-Central Chinese practices, mostly from the Han people. The 4 main components are theory, diagnosis and prescription, herbal medicine, and accupuncture.

    1987-01-01

    Thailand has achieved a remarkable population revolution in the past 15 years, resulting in a fertility decline of 44%, the 3rd greatest decline of the major developing countries. Thailand is quite distinct from either China or South Korea, the leaders in fertility decline. It has neither China's authoritarian power system to enforce population control nor the highly developed, Westernized outlook of South Korea. Instead it achieved its astounding fertility drop through a noncoercive family planning program operating within a context of rapid social change and a cultural setting. Thailand's drop in population growth has touched almost all segments of Thai society. The preferred number of children among couples married less than 5 years has dropped in both rural and urban families at almost exactly the same rate, from about 3.2 in 1969 to 2.3 in 1984. Religious groups represent the only substantial difference in family size preference; Moslem women married less than 5 years stated a desired average of 3.1 children versus 2.3 for Buddhist women. The direct case of the fertility drop is a national increase in contraceptive use. In 1984, 65% of Thai women reported using contraception. The Thai population, however, was ripe for using contraception when it became available due to 1) mass media creating a desire for consumer goods, 2) the increased costs of education to parents, 3) the willingness of parents to trade off "parent repayment" from many children for a few quality children, 4) couples' autonomy in fertility decision making, 5) the high status of women in Thailand, and 6) the fact that Buddhism poses no barriers to contraception. Current trends show no immediate sign of change.

Ukraine’s presidential elections of 2004 and the competition between Viktor Yushchenko and Victor Yanukovich and the presence of international observers in the process of elections and the controversy of electoral fraud and the West’s support of Yushchenko were all directed toward the formation of a color revolution in Ukraine. Poor economic conditions and official corruption, religious, linguistic, class and racial gaps in Ukraine led the way for foreigners to use them in creating electoral situations and prepare the fall of the government. The main purpose question in this article is the Orange Revolution and its causes.

  8. A Revolution that never happened.

    If we define scientific revolutions as changes of scientists' ontologies, types of causal explanation, and paradigmatic types of methods and instruments, Antoine-Laurent Lavoisier's contribution to chemistry did not amount to a scientific revolution. Contrary to the received view that Lavoisier initiated a "chemical revolution," which is accepted by Chang and Kusch, I argue that Lavoisier shared with the phlogistonists their "flat ontology" of chemical substance, established decades before the 1770s, their types of explaining chemical transformation, and their quantitative methods. Based on my historical reconstruction, I criticize Chang's argument that the late eighteenth-century phlogistic systems and Lavoisier's system belonged to two different theoretical traditions. As a consequence, I also question Chang's argument that the acceptance of Lavoisier's system can be explained in terms of dominance of "compositionism" over "principlism."

  14. Ruin and Revolution in ``Hamlet."

    Usher, P. D.

    1999-05-01

    In the cosmic allegorical interpretation of Shakespeare's "Hamlet" (BAAS 28, 859 & 1305, 1996; Mercury 26:1, 20, 1997; RPS 18:3, 6, 1997; Giornale di Astronomia 24:3, 27, 1998), the usurper King Claudius, namesake of Ptolemy, personifies geocentricity. Textual support for this reading is found in 1.2 where Hamlet is associated with the Sun, as befits a rightful heir, while Claudius is associated with the Earth. In 3.3 Claudius fears Hamlet's antics. Rosencrantz states that the lives of many depend on the well-being of the King. He warns that if the King were to be imperiled, his subjects, those "ten thousand lesser things", would fall in a "boisterous ruin" along with "each small annexment" and "petty consequence." These 10,000 lesser lights are the naked eye stars (mv ~ 6.5) which would collapse with the demise of the pre-Diggesian firmament, along with ancient planets and their geometrical contrivances. In 5.1 Shakespeare puns on "De revolutionibus" when he refers to "fine revolution." The double meaning of "revolution" (alteration, orbital motion) was in use long before 1600. Since "revolution" is used in the context of digging, it may refer as much to the Diggesian as the Copernican Revolution. Shakespeare's prescience is revealed by his anticipation of change, as encapsulated geocentricity is transformed to stellar boundlessness, while his presence is suggested by fatherly concerns and ghost-like direction.

    Full Text Available Green computing is the study and practice of using computing resources efficiently. This give idea about reduce the use of hazardous materials maximize energy efficiency during the product's lifetime, and promote recyclability. Green computing can be broadly defined as the problem of reducing the overall carbon footprint of computing and communication infrastructure, such as data centers, by using energy-efficient design and operations. As the environmentalists and energy conservationists ponder over the issue of conserving environment, technologists have come out with a simple solution to let you contribute to the “Go Green” campaign- with the help of Green PCs. By using green computing practices; you can improve energy management, increase energy efficiency, reduce e-waste, and save money. Taking into consideration the popular use of information technology industry, it has to lead a revolution of sorts by turning green in a manner no industry has ever done before. It is worth emphasizing that this “green technology” should not be just about sound bytes to impress activists but concrete action and organizational policy. The plan towards Green PC should include new electronic products and services with optimum efficiency and all possible options towards energy savings and technical issues in high-performance green computing span the spectrum from green infrastructure like energy-efficient buildings, intelligent cooling systems, green power sources for green hardware multi-core computing systems, energy-efficient server design, energy-efficient solid-state storage for green software and applications.

    The advent of international wideband communication by optical fibre has produced a revolution in communications and the use of the internet. Many African countries are now connected to undersea fibre linking them to other African countries and to other continents. Previously international communication was by microwave links through geostationary satellites. These are becoming redundant in some countries as optical fibre takes over, as this provides 1000 times the bandwidth of the satellite links. In the 1970's and 1980's some two dozen large (30 m diameter class) antennas were built in various African countries to provide the satellite links. Twenty six are currently known in 19 countries. As these antennas become redundant, the possibility exists to convert them for radio astronomy at a cost of roughly one tenth that of a new antenna of similar size. HartRAO, SKA Africa and the South African Department of Science and Technology (DST) have started exploring this possibility with some of the African countries...

    Several bovine, human and porcine endothelial cell lines, bovine fetal gastrointestinal cells (BFGC), Madin-Darby bovine kidney (MDBK) and African green monkey kidney (VERO) cells were exposed in vitro to sporozoites of Eimeria bovis. Parasites invaded all cells used and changed their shape to more stumpy forms within 12 h. Sporozoites left their host cells and invaded new ones frequently within the first 12 h post-infection. Further development took place only in bovine cells, although parasites survived in the other cells for at least 3 weeks. Within the non-bovine cells, conspicuously enlarged parasitophorous vacuoles developed in VERO cells and reached a diameter of 15-20 microm. The best development to first generation schizonts with regard both to time required to mature, to schizont size and to merozoite yields was observed in BFGC, followed by bovine umbilical vein and bovine spleen lymphatic endothelial cells. MDBK cells were less suitable. The life cycle was completed (development of oocysts) only occasionally in BFGC. Results are considered under several aspects. Thus, infected VERO cells may represent a suitable tool for studying the parasitophorous vacuole, while infected endothelial cells represent a system quite narrow to the in vivo situation and should allow basic studies on parasite/host cell interactions and BFGC can be used for the mass production of E. bovis first generation merozoites.

    Full Text Available Paper presents a family of helical two-revolutional cyclical surfaces, which arecreated by movement of the circle alongside the helical cycloidal curve, where circle islocated in the curve normal plane and its centre is on this curve. Helical cycloidal curvecan be created by simultaneous revolution of a point about two different axes 3o, 2o and byscrewing about axis 1o in the space. Form of the helical cycloidal curve and also of thehelical two-revolutional cyclical surface is dependent on the relative position of the threeaxes of revolutions, on multiples of angular velocities and orientations of separaterevolutions. Analytic representation, classification of surfaces and some of their geometricproperties are derived.

Following his observations of the heavenly bodies, Nicolaus Copernicus (1473-1543) abandoned the geocentric system for a heliocentric model, with the sun at the center. His remarkable work, On the Revolutions of Heavenly Spheres, stands as one of the greatest intellectual revolutions of all time, and profoundly influenced, among others, Galileo and Sir Isaac Newton.

    In the 19th century, the United Kingdom began a period of economic transformation known as the Industrial Revolution. It’s commonly believed that this era opened as new inventions improved the technologies used to produce goods and provide services. However, we now know that such improvements affected only a relatively small part of the economy. Nonetheless, output rose during the first stage of the Industrial Revolution because of capital accumulation. One explanation for this increase in ca...

  2. Epilepsy genetics: the ongoing revolution.

    Science.gov (United States)

    Lesca, G; Depienne, C

    2015-01-01

    Epilepsies have long remained refractory to gene identification due to several obstacles, including a highly variable inter- and intrafamilial expressivity of the phenotypes, a high frequency of phenocopies, and a huge genetic heterogeneity. Recent technological breakthroughs, such as array comparative genomic hybridization and next generation sequencing, have been leading, in the past few years, to the identification of an increasing number of genomic regions and genes in which mutations or copy-number variations cause various epileptic disorders, revealing an enormous diversity of pathophysiological mechanisms. The field that has undergone the most striking revolution is that of epileptic encephalopathies, for which most of causing genes have been discovered since the year 2012. Some examples are the continuous spike-and-waves during slow-wave sleep and Landau-Kleffner syndromes for which the recent discovery of the role of GRIN2A mutations has finally confirmed the genetic bases. These new technologies begin to be used for diagnostic applications, and the main challenge now resides in the interpretation of the huge mass of variants detected by these methods. The identification of causative mutations in epilepsies provides definitive confirmation of the clinical diagnosis, allows accurate genetic counselling, and sometimes permits the development of new appropriate and specific antiepileptic therapies. Future challenges include the identification of the genetic or environmental factors that modify the epileptic phenotypes caused by mutations in a given gene and the understanding of the role of somatic mutations in sporadic epilepsies.

    Full Text Available It is important to reconsider the measurements which refer to the “Wealth of Nations” and from which the most appropriate references for better welfare policies are derived. In the present Service Economy, not all the “value added” measures indicate an increase in the level of wealth (the costs to cope with pollution for instance, whereas many developments in service functions and performances (in the case of many communication systems for instance add to real wealth much more than the usual value added references indicate. In particular, the notion of productivity in a Service economy is much more relevant with reference to performance in time (hence in a probabilistic system than to the production factor costs (in an equilibrium-based system. But all this is linked to progress in economics as a discipline, and to its integration with environmental issues (which also pretend to solve the problems of the “Wealth of Nations” on the basis of their “sustainability”. This will be a new era in economic development which will be beyond current extrapolations and will hope for “growth” in the traditional Industrial Revolution perspective.

  5. EDITORIAL: The next photonic revolution The next photonic revolution

    2009-11-01

    This special section on Nanophotonics and Metamaterials is a follow-up to the second European Topical Meeting of the NANOMETA series of meetings (see www.nanometa.org) which took place on 5-8 January 2009, in Seefeld, Austria. The main idea of the first NANOMETA meeting held in 2007 was to bring together the mature community of microwave electrical engineers with the emerging community of photonics researchers interested in the physics of light coupled to nanostructures. In recent years the research landscape has shifted dramatically. A wider proliferation of nanofabrication techniques such as electron beam lithography, nanoimprint and focused ion beam milling, diagnostics techniques such as near-field scanning imaging, cathodoluminescence with nanoscale resolution and micro-spectrometry, and the availability of affordable broadband and ultrafast optical sources, have moved the research focus of the NANOMETA community to the optical domain. Quite naturally the ideas of the nonlinearity of materials and the coherency of light in the nanoscale realm have been widely discussed. Driven by the dream of untapped device and material functionality, nonlinear and switchable nanophotonic devices and photonic metamaterials, along with the concept of tailoring the electromagnetic space with metamaterials, appear to be the main avenues along which the subject will develop in the coming years. Indeed, in the last 20 years photonics has played a key role in creating the world as we know it, with enormous beneficial social impact worldwide. It is impossible to imagine modern society without the globe-spanning broadband internet and mobile telephony made possible by the implementation of optical fibre core networks, optical disc data storage (underpinned by the development of compact semiconductor lasers), modern image display technologies and laser-assisted manufacturing. We now anticipate that the next photonic revolution will continue to grow, explosively fuelled by a new

  8. Hacking the quantum revolution: 1925-1975

    Science.gov (United States)

    Schweber, Silvan S.

    2015-01-01

    I argue that the quantum revolution should be seen as an Ian Hacking type of scientific revolution: a profound, longue durée, multidisciplinary process of transforming our understanding of physical nature, with deep-rooted social components from the start. The "revolution" exhibits a characteristic style of reasoning - the hierarchization of physical nature - and developed and uses a specific language - quantum field theory (QFT). It is by virtue of that language that the quantum theory has achieved some of its deepest insights into the description of the dynamics of the physical world. However, the meaning of what a quantum field theory is and what it describes has deeply altered, and one now speaks of "effective" quantum field theories. Interpreting all present day quantum field theories as but "effective" field theories sheds additional light on Phillip Anderson's assertion that "More is different". This important element is addressed in the last part of the paper.

    Societies before the Industrial Revolution were dependent on the annual cycle of plant photosynthesis for both heat and mechanical energy. The quantity of energy available each year was therefore limited, and economic growth was necessarily constrained. In the Industrial Revolution, energy usage increased massively and output rose accordingly. The energy source continued to be plant photosynthesis, but accumulated over a geological age in the form of coal. This poses a problem for the future. Fossil fuels are a depleting stock, whereas in pre-industrial time the energy source, though limited, was renewed each year.

    We present an algorithm for extracting the axis of revolution from the implicit equation of an algebraic surface of revolution based on three distinct computational methods: factoring the highest order form into quadrics, contracting the tensor of the highest order form, and using univariate resultants and gcds. We compare and contrast the advantages and disadvantages of each of these three techniques and we derive conditions under which each technique is most appropriate. In addition, we provide several necessary conditions for an implicit algebraic equation to represent a surface of revolution. PMID:26561460

  15. Was there an ‘Industrious Revolution' before the Industrial Revolution?

    DEFF Research Database (Denmark)

    Allen, Robert C.; Weisdorf, Jacob Louis

    It is conventionally assumed that the pre-modern working year was fixed and that consumption varied with changes in wages and prices. This is challenged by the twin theories of the ‘industrious' revolution and the consumer revolution, positing a longer working year as people earned surplus money...... to buy novel goods. In this study, we turn the conventional view on its head, fixing consumption rather than labour input. Specifically, we use a basket of basic consumption goods and compute the working year of rural and urban day labourers required to achieve that. By comparing with independent...... estimates of the actual working year, we find two ‘industrious' revolutions among rural workers; both, however, are attributable to economic hardship, and we detect no signs of a consumer revolution. For urban labourers, by contrast, a growing gap between their actual working year and the work  required...

    CERN Document Server

    2016-01-01

    This volume provides an in-depth discussion on the central question – how can people express and survive dissent and disagreement in confined habitats in space? The discussion is an important one because it could be that the systems of inter-dependence required to survive in space are so strong that dissent becomes impossible. John Locke originally said that people have a right to use revolution to overthrow a despotic regime. But if revolution causes violence and damage that causes depressurisation with the risk of killing many people, is it even permissible to have a revolution? How then are people to express their liberty or dissatisfaction with their rulers? The emergence of structures of dissent and disagreement is an essential part of the construction of a framework of liberty in space (revolution is just the extreme example) and thus the topic deserves in-depth and immediate attention. Even today, the way in which we assemble organisations and corporations for the government and private exploration o...

  4. The 'Shale Gas Revolution'. Hype and Reality

    International Nuclear Information System (INIS)

    The 'shale gas revolution' - responsible for a huge increase in unconventional gas production in the US over the last couple of years - is creating huge investor uncertainties for international gas markets and renewables and could result in serious gas shortages in 10 years time. This report casts serious doubt over industry confidence in the 'revolution', questioning whether it can spread beyond the US, or indeed be maintained within it, as environmental concerns, high depletion rates and the fear that US circumstances may be impossible to replicate elsewhere, come to the fore. Investor uncertainty will reduce investment in future gas supplies to lower levels than would have happened had the 'shale gas revolution' not hit the headlines. While the markets will eventually solve this problem, rising gas demand and the long lead-in-times on most gas projects are likely to inflict high prices on consumers in the medium term. The uncertainties created by the 'shale gas revolution' are also likely to compound existing investor uncertainty in renewables for power generation in the aftermath of Copenhagen. The serious possibility of cheap, relatively clean gas may threaten investment in more expensive lower carbon technologies.

  11. Hypercars: The next industrial revolution

    Energy Technology Data Exchange (ETDEWEB)

    Lovins, A.B.; Barnett, J.W.; Lovins, L.H.

    1996-02-01

    The auto industry -- one-seventh of the GNP, and the highest expression of the Iron Age -- is about to trigger the biggest transformation in industrial structure since the microchip. Ultralight cars molded from net-shape advanced composites can be several-fold lighter than present steel cars, yet safer, sportier, and more comfortable, durable, and beautiful. Modern hybrid-electric drives boost efficiency approximately 1.3-1.5x in heavy steel cars, but approximately 5-20x in ultralight, very slippery plafforms. Synergistically combined into ultralight-hybrid `hypercars,` these elements can yield state-of-the-shelf family cars that average 150-300+ mi/gal -- twice that with state-of-the-art technologies -- yet can also be superior in all other respects, probably including cost: carbon-fiber monocoques can actually be cheaper to mass-produce that steel unibodies. Designing cars more like aircraft and less like tanks requires not only an approximately 400-500 kg curb mass and very low air and road drag, but also an aerospace philosophy of engineering integration. Mass, cost, and complexity turn out to compound with heavy hybrids but to decompound with ultralight hybrids, owing partly to radical simplification. Excellent aerodynamics, preferable including advanced techniques for passive boundary-layer control, will be the key to successful design integration. Transforming automaking is a competitive and environmental imperative, could form the nucleus of a green industrial Renaissance, and would enhance national security by, among other things, saving as much oil as OPEC now extracts. However, this transformation faces serious cultural barriers. For example, hypercars will be more like computers with wheels than like cars with chips -- they`ll have an order of magnitude more code than today`s cars -- but Detroit is not a software culture. Just the transition from stamped and welded steel to integrated and adhesive-joined synthetics is difficult enough.

    The auto industry -- one-seventh of the GNP, and the highest expression of the Iron Age -- is about to trigger the biggest transformation in industrial structure since the microchip. Ultralight cars molded from net-shape advanced composites can be several-fold lighter than present steel cars, yet safer, sportier, and more comfortable, durable, and beautiful. Modern hybrid-electric drives boost efficiency approximately 1.3-1.5x in heavy steel cars, but approximately 5-20x in ultralight, very slippery plafforms. Synergistically combined into ultralight-hybrid 'hypercars,' these elements can yield state-of-the-shelf family cars that average 150-300+ mi/gal -- twice that with state-of-the-art technologies -- yet can also be superior in all other respects, probably including cost: carbon-fiber monocoques can actually be cheaper to mass-produce that steel unibodies. Designing cars more like aircraft and less like tanks requires not only an approximately 400-500 kg curb mass and very low air and road drag, but also an aerospace philosophy of engineering integration. Mass, cost, and complexity turn out to compound with heavy hybrids but to decompound with ultralight hybrids, owing partly to radical simplification. Excellent aerodynamics, preferable including advanced techniques for passive boundary-layer control, will be the key to successful design integration. Transforming automaking is a competitive and environmental imperative, could form the nucleus of a green industrial Renaissance, and would enhance national security by, among other things, saving as much oil as OPEC now extracts. However, this transformation faces serious cultural barriers. For example, hypercars will be more like computers with wheels than like cars with chips -- they'll have an order of magnitude more code than today's cars -- but Detroit is not a software culture. Just the transition from stamped and welded steel to integrated and adhesive-joined synthetics is difficult enough. Nonetheless

    2015-02-01

    In a number of papers and in his recent book, Is Water H2O? Evidence, Realism, Pluralism (2012), Hasok Chang has argued that the correct interpretation of the Chemical Revolution provides a strong case for the view that progress in science is served by maintaining several incommensurable "systems of practice" in the same discipline, and concerning the same region of nature. This paper is a critical discussion of Chang's reading of the Chemical Revolution. It seeks to establish, first, that Chang's assessment of Lavoisier's and Priestley's work and character follows the phlogistonists' "actors' sociology"; second, that Chang simplifies late-eighteenth-century chemical debates by reducing them to an alleged conflict between two systems of practice; third, that Chang's evidence for a slow transition from phlogistonist theory to oxygen theory is not strong; and fourth, that he is wrong to assume that chemists at the time did not have overwhelming good reasons to favour Lavoisier's over the phlogistonists' views.

  17. Health and the urban environment: revolutions revisited

    2009-05-15

    From cholera pandemics to smog episodes, urban development driven by narrow economic interests has shown itself to be a serious threat to human health and wellbeing. Past revolutions in sanitation and pollution control demonstrate that social movements and governance reforms can transform an urban health penalty into a health advantage. But many environmental problems have been displaced over time and space, and never truly resolved. Health concerns need once again to drive an environmental agenda – but this time it must be sustainable over the long haul, and globally equitable. With the global economic crisis raising the ante, what's needed is no less than a revolution in environmental justice that puts health, not economics, at the core of its values.

    The recent Ebola crisis has re-opened the debate on global health governance and the role of the World Health Organization. In order to analyze what is at stake, we apply two conceptual approaches from the social sciences - the work on gridlock and the concept of cosmopolitan moments - to assess the ability of the multilateral governance system to reform. We find that gridlock can be broken open by a health crisis which in turn generates a political drive for change. We show that a set of cosmopolitan moments have led to the introduction of the imperative of health in a range of policy arenas and moved health into 'high politics' - this has been called a political revolution. We contend that this revolution has entered a second phase with increasing interest of heads of state in global health issues. Here lies the window of opportunity to reform global health governance.

  20. The Nineteenth-Century Revolution in Astronomy

    Science.gov (United States)

    Batten, Alan Henry

    2015-08-01

    The term "revolution" in scientific contexts usually refers either to the beginnings of modern western science in the sixteenth and seventeenth centuries, or to the two great revolutions of early twentieth century physics. Comparison of what was known at the beginning of the nineteenth century with what was known at the end, however, shows that century to have been one of transformation in astronomy, and in the other sciences, that amounts to "revolution". Astronomers in 1800 knew neither the nature of the Sun nor the distances of the stars. Developments in instrumentation enabled the first determinations of stellar parallax in the 1830s, and later enabled the solar prominences to be studied outside the brief momemnts of total eclipses. The development of photography and of spectroscopy led to the birth of observational astrophysics, while the greater understanding of the nature of heat and the rise of thermodynamics made possible the first attempts to investigate the theory of stellar structure. Nothing was known in 1800 of extra-galactic objects apart from some tentative identifcations by William Herschel but, by the end of the century, the discovery of the spiral structure of some nebulae had led some to believe that these were the "island universes" about which Kant had speculated. Of course, astrophysics and cosmology would be much further developed in the twentieth century and those of us whose careers spanned the second half of that century look back on it as a "golden age" for astronomy; but the nineteenth century was undoubtedly a time of rapid transformation and can be reasonably described as as one of the periods of revolution in astronomy.

    Full Text Available The .Industrial Engineer is caught between the Industrial Revolution and the Information revolution. He is confronted with choosing between pragmatic improvements in productivity and efficiency of a single operation or the opportunistic modelling and reshaping of the networked "virtual enterprise" to become more competitive in a global marketplace . The diagram below depicts the different extremes of the Industrial Engineering timeline. This implies that the two societies (Industrial and information might have conflicting characteristics which requires careful repositioning of the Industrial Engineer to ensure that the benefits that can be obtained from the two societies are maximised.

    This paper documents the development of Industrial engineering , then evaluates the nature of the much publicized Information revolution and its impact on society. In order to establish the nature and composition of contemporary Industrial Engineering in the 1990' s, an analysis and categorization of the literature in four journals for the last two years are performed. This is enhanced with an INTERNET search into Industrial Engineering Research and developments that are currently under development.

    2014-01-01

    Was there a Darwinian Revolution and was it but part of the Scientific Revolution? Before Thomas Kuhn's Structure of Scientific Revolutions in 1962, most people thought that there was a Darwinian Revolution, that it was in some sense connected to the Scientific Revolution, but that neither question nor answer was terribly interesting. Then revolutions in science became a matter of intense debate, not so much about their very existence but about their nature. Was there a switch in world-views? Did the facts change? What was the importance of social groups? And so forth. Recently however some students of the history of science have started to argue that the very questions are misconceived and that there cannot have been a Darwinian Revolution and its relationship to the Scientific Revolution is imaginary because there are no such revolutions in science! This paper takes a sympathetic look at these issues, concluding that there is still life in the revolution-in-science issue, that Kuhn's book was seminal and still has things of importance to say, but that matters are more complex and more interesting than we thought back then.

    Mainly driven by changes in the orbital characteristics of Earth around the sun, the planet's climate has been continuously changing over periods of tens of thousands of years. However, the warming that has been detected in the Earth's atmosphere over the last century is occurring at a rate that cannot be explained by any known natural cycle. Main-stream science has indeed reached consensus that the 'enhanced green house effect', caused by the interplay of incoming short-wave irradiation, outgoing long-wave radiation and the absorption of energy by enhanced levels of CO2 and water vapour in the troposphere, is the main forcing mechanism responsible for the phenomena of global warming. The enhanced greenhouse effect strengthens the 'natural green house effect' that results from the CO2 and water vapour occurring naturally in the atmosphere. The continuous burning of fossil fuels since the industrial revolution and the simultaneous degradation of large forests, are the main reasons for the increase in CO2 concentrations in the atmosphere. The availability of climate change projection data varies considerably for different areas on Earth. Whereas the data centres storing climate change projections for Europe and North America now store petabytes of data, regionally downscaled projections for Africa are rarely available. In the context of the research project CLUVA, (Assessing vulnerability of urban systems, populations and goods in relation to natural and man-made disasters in Africa, co-funded by the European Commission under grant agreement no: 265137), the Council for Industrial and Scientific Research (CSIR) in South Africa and the Centro Euro-Mediterraneo sui Cambiamenti Climatici (CMCC) in Italy have produced a large set of projections of climate change over Africa, covering the time period 1950 to 2100.

    The USN's Landing Craft Air Cushion (LCAC) vehicle's operational capabilities represent not only a revolution in amphibious warfare, but may also prove to bear an evolutionary relationship to other naval mission requirements. After a brief development history of LCAC is presented, attention is given to anticipated uses of this vehicle beyond that of its landing-craft design mission. These missions encompass ASW, antiaircraft, antisurface shipping, and electronic warfare, as well as mine warfare and mine countermeasures. In virtually all such scenarios, the LCAC will retain its current configuration; where modifications must be made, they may be accomplished with easily removed retrofit 'kits'.

  3. Why the Pre-Copernican Cosmological Revolution Was Not a Revolution?

    Science.gov (United States)

    Pacholczyk, A. G.

    The 'scientific component' of the Copernican cosmological revolution followed a seemingly minor local structural change (consisting of the transposition of the Earth and the Sun), initially not affecting the global Platonic-Aristotelian spherical symmetry of the Universe and the general arrangement of astronomical bodies at sufficiently large distances from its center. Yet this change resulted in a rich 'ideological component' of the Copernican revolution in the Popperian sense; the importance of this ideological component is generally regarded as a consequence of the tensions arising from apparent contradictions between the new cosmos and several Scriptural passages (as if the previous Platonic-Aristotelian cosmos were in perfect agreement with the Scriptures, which certainly was not the case). The scientific component of the pre-Copernican cosmological revolution (replacing the plane-parallel scriptural cosmos with the spherically symmetric non-scriptural Universe of Plato and Aristotle), was a major global change in the large-scale structure of the Universe. This change took place at different times in different places in Christendom, and was by no means ideologically revolutionary: the pre-Copernican revolution had a very insignificant 'ideological component'. In this paper, after examining this transition in more detail, we shall ask the pertinent question: why did the pre-Copernican cosmological revolution not have any significant 'ideological component'? If the God-created Universe could be depicted in the opinion of the majority of Church Fathers and Schoolmen by the (non-scriptural) spherically symmetric Platonic or Aristotelian model as well as by the (scriptural) tabernacular Babylonian model, then why couldn't it be described just as well in the opinion of 17th century churchmen by the (also non-scriptural) Copernican model? The paper suggests that the tentative answers to these questions are provided by different anthropocentric ramifications of

    North American cities face many major environmental and health issues such as urban heat island effect, the intensity of storms, microclimate around buildings, imperviousness of sites, poor air quality and increases in respiratory disease. Several new technologies are starting to address global impacts and community level issues as well as the personal health and comfort of building occupants. These include green towers, living walls, vegetated rooftops and ecological site developments. This paper examined these forms of eco-development and presented their benefits. It discussed green walls in Japan; green towers in Malaysia, Singapore and Great Britain; green facades of climbing plants; active living walls in Canada; and passive living walls in France and Canada. It also discussed thermal walls; thematic walls; vertical gardens and structured wildlife habitat. Last, it presented testing, monitoring, research and conclusions. The Centre for the Advancement of Green Roof Technology is setting up a program to test thermal performance, to assess plant survival and to monitor green walls at the British Columbia Institute of Technology in Vancouver, Canada as much of the research out of Japan is only available in Japanese script. It was concluded that green architecture can provide shade, food, rainwater, shelter for wildlife and mimic natural systems. 15 refs.

It points out that this extension of marriage to same-sex couples would not have been possible if it was not for the groundbreaking decisions on sexual orientation discrimination handed down by the South African Constitutional Court over the past ten years. It al so describes the complex legal regime now in place which allows different sex couples to enter into marriage in terms of a traditional Marriage Act or the new Civil Union Act but restricts same-sex couples to entering into marriage in terms of the latter Act. The article concludes that while this extension of marriage rights can be viewed as a legal revolution, some problems remain with the legal regulation of same-sex relationships in South Africa.

  18. Rethinking "relevance": South African psychology in context.

    Science.gov (United States)

    Long, Wahbie

    2013-02-01

    This article examines the phenomenon known as the "relevance debate" in South African psychology. It begins with a historical overview of the contours of the discipline in that country before describing the controversy's international dimensions, namely, the revolutionary politics of 1960s higher education and the subsequent emergence of cognate versions of the debate in American, European, and "Third World" psychology. The article then details how South Africa's "relevance" project enjoyed a special affinity with an assortment of ethnic-cultural, national, and continental myths and metaphors, all of which served the interests of the political formations of the day. It discusses how, in present-day South Africa, the intelligentsia has become an important catalyst for the so-called African Renaissance, which seeks to provide "relevant" solutions for the regeneration of African society. However, the global hegemony of what began in the 1970s as a "second academic revolution," aided by the lifting of the academic boycott of South Africa, has blunted the once critical edge of "relevance" discourse. A new mode of knowledge production now holds sway, the outcome of a dramatic reformulation of the capitalist manifesto in which the values of the "May 68" generation have been hijacked by a managerialist rationality. In light of the capitalization of the knowledge-production enterprise, it is concluded that the idiom of "relevance" has outlived its usefulness. PMID:23421936

    Full Text Available In this study, humor and the confused feelings of overwhelming happiness, fear, and uncertainty intertwine to reflect Tunisians’ attitudes, beliefs, feelings, and experiences in the aftermath of the revolution. The study adopts a blended netnography/ethnography approach to data collection and analysis. My original data consist of 2 hrs of recorded discussions of 60 Tunisian students and a total of 300 online humorous posts collected from the social network Facebook (FB. The data revealed that Tunisians interacting via FB used two main types of situational humor: Third party insult and Alternate reality. These two types of humor were found to be associated with a variety of psychological and social functions and to serve as effective interpersonal strategies to construct group cohesion, strengthen shared attitudes and beliefs, and develop relational identity.

  4. Silicon: Child and Progenitor of Revolution

    Science.gov (United States)

    Cahn, R. W.

    Antoine Lavoisier, the pioneering French chemist who (together with Joseph Priestley in England) identified oxygen as an element and gave it its name, in 1789 concluded that quartz was probably a compound with an as-yet undiscovered but presumably extremely common element. That was also the year in which the French Revolution broke out. Five years later, the Jacobins accused Lavoisier of offences against the people and cut off his head, thereby nearly cutting off the new chemistry. It was not until 1824 that Jöns Berzelius in Sweden succeeded in confirming Lavoisier's speculation by isolating silicon. Argument at once broke out among the scientific elite as to whether the newly found element was a metal or an insulator. It took more than a century to settle that disagreement decisively: As so often, when all-or-nothing alternatives are fiercely argued, the truth turned out to be neither all nor nothing.

  6. Revolution, Romanticism and the Long Nineteenth Century

    Directory of Open Access Journals (Sweden)

    Adriana Craciun

    2006-04-01

    Full Text Available In order to consider the future of Victorian literary studies within the long nineteenth century, we must go back to that earlier “period” of the nineteenth century, and the French Revolution of 1789. Drawing on the aesthetic and political innovations of 1790s women's writings, this essay argues that we need to reconceive of nineteenth-century literary studies beyond the period boundaries of Romantic and Victorian. The sexualization of revolutionary Terror, and particularly of Robespierre, in Romantic-era writings by women like Helen Maria Williams, Mary Robinson and Fanny Burney, offers surprising precedents for the feminization of Terror associated with the retrospectives of Victorian writers like Carlyle and Dickens. In this respect, and given many other aesthetic continuities (for example, the crossgender and cross-period appeal of the “poetess” figure, the “Victorian period” appears increasingly unsatisfactory when compared to the merits of a long nineteenth-century model for literary studies.

  7. The quiet revolution: decentralisation and fuel cells

    International Nuclear Information System (INIS)

    This article discusses how major changes in the electricity supply industry can take place in the next few years due to market liberalisation and efforts to reduce the emission of greenhouse gasses. Decentralisation is discussed as being a 'mega-trend' and fuel cells in particular are emphasised as being a suitable means of generating heat and power locally, i.e. where they are needed. Also, the ecological advantages of using natural gas to 'fire' the fuel cell units that are to complement or replace coal-fired or gas-fired combined gas and steam-turbine power stations is discussed. Various types of fuel cell are briefly described. Market developments in the USA, where the power grid is extensive and little reserve capacity is available, are noted. New designs of fuel cell are briefly examined and it is noted that electricity utilities, originally against decentralisation, are now beginning to promote this 'quiet revolution'

    Devyn Spence Benson

    2012-12-01

    Full Text Available “Owning the Revolution” explores the role that conversations about race and racism played in defining the 1959 Cuban Revolution both on the island and in South Florida, where over half of the exiles fled. It highlights how revolutionary leaders challenged internal and external opposition movements by publicly labeling dissenters “counterrevolutionaries” and “racists.” Using the label “racist” to attack an opponent was not altogether new in the 1960s, but by linking the term to counterrevolution, national discussions occurring in newspapers, magazines, and on television defined public racism as existing outside of the norms of a new Cuba. Exiles disagreed with this identification and accused the revolution of betraying the nineteenth-century colorblind goals of Jose Martí. Exile leaders in Miami argued that Castro invented racial tensions and claimed that their fight was not with blacks or mulatos but with “red” or communist Cubans. The politics expressed by white exile newspapers, however, did not always fit with the concerns of Afro-Cubans in the United States. Miami Cubans failed to acknowledge the persistence of racism in new exile communities in the same way that the revolutionary government dismissed racism on the island. These parallel silences exemplify the dangers of polarized narratives that imagine the revolution as antiracist and the exile community as racist.

    International Nuclear Information System (INIS)

    Last week (March 2009) Slovak government extended the preferential treatment of renewable energy. Companies that will produce electricity from biomass, water, wind, solar and underground thermal springs, have guaranteed that they will receive a decently paid at least the next 15 years. It promises them a new government bill on the promotion of renewable energy. So far, the State guaranteed the purchase of green power for only one year in advance. And because it is more expensive than electricity from coal or uranium, green investment firms feared. Fifteen guarantees give assurance. The government will guarantee only purchase green electricity, but also biomethane to produce heat. So, who wants an ordinary agrarian biogas from waste and adjust to such a gas. Slovak gas industry will have to buy it into its network. Biomethane is not in domestic terms only on paper.

  20. Global Greening Is Firm, Drivers Are Mixed

    2015-12-01

    Evidence for global greening is converging, asserting an increase in CO2 uptake and biomass of the terrestrial biosphere. Global greening refers to global net increases in the area of green canopy, stocks of carbon, and the duration of the growing season. The growing seasons in general have prolonged while the stock of biomass carbon has increased and the rate of deforestation has decelerated, although these trends are mixed in the Tropics. Evidence for these trends comes from firm empirical data obtained through atmospheric CO2 observations, remote sensing, forest inventories and land use statistics. The drivers of global greening cannot be assessed based only on unambiguous empirical measurements. They include spatially and temporally heterogeneous combinations of changing land use and management - including green revolution and increasing yields, afforestation, forest protection and management, and abandonment of agricultural land -, changes in the global environment (increased CO2, warmer temperatures and longer growing seasons in the northern latitudes, acceleration of the global nitrogen cycle), and shifts in demand for forest and farm products. The global trade of biomass-derived commodities affects the link between consumption patterns and the land cover impact. Global greening confirms the immediacy of global change and may be associated with more or less biodiversity and diverse environmental and human consequences depending on local circumstances. Understanding causes, mechanisms, and implications of global greening requires integrated analyses spanning land use and management, demand for products of the terrestrial biosphere, and the atmosphere and climate. Understanding the pace and drivers of global greening matters crucially for assessing the future of the terrestrial C sink; ecological, economic, social, and cultural assessments of the bio-economy; and the preservation of ecosystems.

  5. After the US shale gas revolution

    International Nuclear Information System (INIS)

    After 20 years at different positions in the gas sector, from the policy side to trading floors, the author gives an overview of the major gas issues and elaborate on the consequences of the US shale gas revolution. The first part of the book provides basic knowledge and gives needed tools to better understand this industry, that often stands, in sandwich, between upstream oil and utilities. After extensive research, publication and teaching, the author shares his insights on fundamental issues all along the gas chain and explains the price mechanisms ranging from oil-indexing to spot. The second part looks into the future of worldwide gas balance. To supply growing markets, the major resource holder, Russia, is now in direct competition with the major gas producer, the US. China has the potential not only to select the winner but also to decide the pricing principle for all Asian buyers in 2020. As China is a new and growing gas importer and has a lower price tolerance than historical Asian buyers (Japan and South Korea), it is highly possible that, against basic geography, China selects waterborne US LNG vs. close Russian pipe gas, to achieve lower import price. Europe, so risk adverse that it won't be able to take any decision regarding shale gas production on this side of 2020, should see its power fading on the energy scene and would rely more on Russia. Gas geopolitics could tighten Russia stronghold on Europe, on one side, and create a flourishing North America-Asian trade... This book is accessible to all and will particularly interest readers seeking a global gas perspective where economics and geopolitics mix. It can be read as an economic novel where billions of $ are invested to shape tomorrow energy world or as a geopolitical thriller where Russia and the US compete to impose their respective agenda, leaving China to select the winner.

    Full Text Available The Industrial Revolution had a negative impact on both the city and the environment. By the second half of the 19th century, the urban erosion of industrial cities cried for direct intervention and curing. The methods developed either along an urban or an anti-urban philosophy: they resulted in the new models of green belt systems aimed at solving all the main urban problems with restructuring the urban fabric, controlling the urban spread into the rural landscape, the lack of green areas and open spaces for recreation and social life, and the lack of green spaces for ventilation. Nowadays, the major cities and capitals around the globe are competing for titles such as healthier, more liveable or even greener city. Given the unfortunate attributes of the urban structure in the historical cities, the development of new transportation sites or green areas is an extremely difficult issue. On the other hand, in the big cities, the brownfield sites are considered as reserve areas for sustainable urban development. Reusing the brownfields and rust areas is already a land saving urban development approach and in case of a complex and ecological urban rehabilitation it can underlie the development of an efficient urban green system and green network.

    Bai, ZhengFeng; Zhao, Yang; Wang, XingGui

    2013-08-01

    In this work, the prediction of wear for revolute joint with clearance in multibody systems is investigated using a computational methodology. The contact model in clearance joint is established using a new hybrid nonlinear contact force model and the friction effect is considered by using a modified Coulomb friction model. The dynamics model of multibody system with clearance is established using dynamic segmentation modeling method and the computational process for wear analysis of clearance joint in multibody systems is presented. The main computational process for wear analysis of clearance joint includes two steps, which are dynamics analysis and wear analysis. The dynamics simulation of multibody system with revolute clearance joint is carried out and the contact forces are drawn and used to calculate the wear amount of revolute clearance joint based on the Archard's wear model. Finally, a four-bar multibody mechanical system with revolute clearance joint is used as numerical example application to perform the simulation and show the dynamics responses and wear characteristics of multibody systems with revolute clearance joint. The main results of this work indicate that the contact between the joint elements is wider and more frequent in some specific regions and the wear phenomenon is not regular around the joint surface, which causes the clearance size increase non-regularly after clearance joint wear. This work presents an effective method to predict wear of revolute joint with clearance in multibody systems.

Given their resistance, how can health system Leaders engage them in redesigning care? In this article, Dr. Thomas H. Lee, Press Ganey's chief medical officer, and Dr. Toby Cosgrove, the CEO of the Cleveland Clinic, describe a framework they've developed for encouraging buy-in. Adapting Max Weber's "typology of motives," and applying behavioral economics and other motivational principles, they describe four tactics leadership must apply in concert: engaging doctors in a noble shared purpose; addressing their economic self-interest; leveraging their desire for respect; and appealing to their sense of tradition. Drawing from experiences at the Mayo Clinic, Geisinger Health System, Partners HealthCare, the Cleveland Clinic, Ascension Health, and others, the authors show how the four motivational levers work together to bring this critical group of stakeholders on board.

    2012-01-01

    The year 2012 marks the 50th anniversary of the publication of Thomas S. Kuhn's The Structure of Scientific Revolutions. Up until recently, the book's philosophical reception has been shaped, for the most part, by the debates and the climate in philosophy of science in the 1960s and 1970s; this new collection of essays takes a renewed look at this work. This volume concentrates on particular issues addressed or raised in light of recent scholarship and without the pressure of the immediate concerns scholars had at the time of the Structure's publication. There has been extensive research on all of the major issues concerning the development of science which are discussed in Structure, work in which the scholars contributing to this volume have all been actively involved. In recent years they have pursued novel research on a number of topics relevant to Structure's concerns, such as the nature and function of concepts, the complexity of logical positivism and its legacy, the relation of history to philosophy o...

  20. Systems biology: leading the revolution in ecotoxicology.

    Garcia-Reyero, Natàlia; Perkins, Edward J

    2011-02-01

    The rapid development of new technologies such as transcriptomics, proteomics, and metabolomics (Omics) are changing the way ecotoxicology is practiced. The data deluge has begun with genomes of over 65 different aquatic species that are currently being sequenced, and many times that number with at least some level of transcriptome sequencing. Integrating these top-down methodologies is an essential task in the field of systems biology. Systems biology is a biology-based interdisciplinary field that focuses on complex interactions in biological systems, with the intent to model and discover emergent properties of the system. Recent studies demonstrate that Omics technologies provide valuable insight into ecotoxicity, both in laboratory exposures with model organisms and with animals exposed in the field. However, these approaches require a context of the whole animal and population to be relevant. Powerful approaches using reverse engineering to determine interacting networks of genes, proteins, or biochemical reactions are uncovering unique responses to toxicants. Modeling efforts in aquatic animals are evolving to interrelate the interacting networks of a system and the flow of information linking these elements. Just as is happening in medicine, systems biology approaches that allow the integration of many different scales of interaction and information are already driving a revolution in understanding the impacts of pollutants on aquatic systems.

    The article combines two objectives: understand the genesis and development of the sociology of Bourdieu in connection with his social and intellectual positioning. The sociology of Bourdieu is a theory of Action which reconciles the double requirement of objectification and taking account of the practical logic bound by social agents. From the character both objective and subjective of social space, he analyzes how different institutions (firstly School) are doing that mental structures match the objective structures of society. By making acceptable reality and registering it in the body, these instances contribute to reproduce social divisions and participate in the work of domination. Gradually, Bourdieu develops a general theory about Power, which leads to a sociology of State. But he refuses any sociological fatalism. Because he perceived homologies between the sociologist and the artist facing the social order, each in their own way, he devoted two researches to Flaubert and Manet, seized in the same enterprise of aesthetic subversion he described as a 'symbolic revolution'. In many aspects, the sociology of Bourdieu opens ways of looking for an objectification of caregivers and their practices.

    Today's digital revolution leads to the increasing mobile device usage, which has changed people's life and work. However, the traditional static display and graphic version is unable to meet the requirements of the modern audience, which makes museums face the challenge in the distribution of knowledge. Meanwhile, the information storm produced by big data emerged a variety of new media, such as social media, Natural User Interface, Augmented Reality, and electronic publishing. This dizzying array of tools offered opportunities for museums all over the world to become more vibrant and accessible. Museums around the world have been constant changed and improved its presentation, which provides a valuable experience for us. The new Shanghai Natural History Museum has also applied information technology on exhibition, education, research and collection. But the change does not mean a complete subversion. Because the museum audience are di- verse, such as born in a different era, have different learning habits, museums need to control the change magnitude of display technology to meet the requirements of different audience.

    The paper investigates the topic of green architecture from an architectural point of view and not an energy point of view. The purpose of the paper is to establish a debate about the architectural language and spatial characteristics of green architecture. In this light, green becomes an adjective...... that describes the architectural exclusivity of this particular architecture genre. The adjective green expresses architectural qualities differentiating green architecture from none-green architecture. Currently, adding trees and vegetation to the building’s facade is the main architectural characteristics...... of green architecture. The paper argues that this greenification of facades is insufficient. The green is only a skin cladding the exterior envelope without having a spatial significance. Through the paper it is proposed to flip the order of words from green architecture to architectural green...

  5. Graham Greene and Cuba: Our man in Havana?

    2008-12-01

    Full Text Available [First paragraph] Graham Greene’s novel Our Man in Havana was published on October 6, 1958. Seven days later Greene arrived in Havana with Carol Reed to arrange for the filming of the script of the novel, on which they had both been working. Meanwhile, after his defeat of the summer offensive mounted by the Cuban dictator, Fulgencio Batista, in the mountains of eastern Cuba, just south of Bayamo, Fidel Castro had recently taken the military initiative: the day after Greene and Reed’s arrival on the island, Che Guevara reached Las Villas, moving westwards towards Havana. Six weeks later, on January 1, 1959, after Batista had fled the island, Castro and his Cuban Revolution took power. In April 1959 Greene and Reed were back in Havana with a film crew to film Our Man in Havana. The film was released in January 1960. A note at the beginning of the film says that it is “set before the recent revolution.” In terms of timing, Our Man in Havana could therefore hardly be more closely associated with the triumph of the Cuban Revolution. But is that association merely accidental, or does it involve any deeper implications? On the fiftieth anniversary of novel, film, and Revolution, that seems a question worth investigating, not with a view to turning Our Man in Havana into a serious political novel, but rather to exploring the complexities of the genre of comedy thriller and to bringing back into view some of the local contexts which might be less visible now than they were when the novel was published and the film released.

    Full Text Available Youth joblessness was one of the main triggers of Tunisia’s January Revolution. Unemployment rate in Tunisia has increased from 13 percent in 2010 to 18.3 percent in 2011 (NIS, 2011. Young people and women are more affected by this increase in unemployment .Thus, the purpose of this study is to examine the effects of various individual and job-related characteristics on the probabilities of unemployment of females and males aged 15–29 and to explore policy actions to create jobs in Tunisia. These issues are addressed using data from a 2010 survey of the National Institute of Statistics that provided information on the employment status of youth aged 15–29. The main estimated results show first that individual’s age, gender, marital status, level of education, sector of economic activity, type of employment and region of residence are significantly related to the unemployment. The results indicate that, for young workers, unemployment incidence increases with the level of education. Education has a greater impact on the unemployment of females than on that of males. Second, there is a negative and significant effect of the agricultural, educational and health sectors on the probability of transition into unemployment for women and men in which case the estimated impact is greater for men. Third, coastal area and public employment are associated with lower probability of transition into unemployment. Finally, Tunisian policymakers are aware of the fact that the elected National Constituent Assembly and the transitional government have a set of challenging tasks to accomplish in order to lower the rate of youth unemployment. For instance, generating funds for business development and infrastructure in non-coastal regions, and collaborating with the private sector to promote investment– whether foreign or domestic – and employment for educated young people.

    Before the discovery of insulin 87 years ago, all diabetic children died within a few weeks or months following diagnosis. Since then, improvements in the treatment and live of young diabetics have sometimes occurred in (r)evolutions that have caused debate among physicians. They are briefly reviewed in this paper. Today's young diabetics, properly trained in self-monitoring and self-treatment, are as competitive physically and intellectually as their non-diabetic peers provided their glycemic control (i.e., their glycated hemoglobin levels) is kept close to normal. They escape the potentially incapacitating complications associated with chronic hyperglycemia of several decades' duration: blindness, renal failure, amputations, excess cardiovascular mortality, etc. To achieve this favourable outcome, diabetic children should be followed by multidisciplinary teams that include pediatric diabetologists and have a large enough case load to acquire a high level of expertise. Quality of care and patient well-being should be compared across teams with the goal of optimizing both these parameters. Any dogmatism must be avoided. The international comparisons of the Hvidøre Study Group on Childhood Diabetes have shown that diabetic children and adolescents on twice-daily free-mix regimens have significantly lower HbA1c than those on basal-bolus, pumps or twice-daily premixed/insulin regimens. Attempts to prevent type 1 diabetes are under way: vitamin D supplementation, avoidance of beta-casein (cow's milk hypothesis), etc. A definitive cure for type 1 diabetes mellitus is difficult to foresee.

  9. Revolutions in twentieth-century physics

    International Nuclear Information System (INIS)

    Relativity theory, quantum mechanics, elementary-particle physics, and cosmology are the four pillars of modern physics. The life in the 21th century is without them no more conceivable: The special relativity theory renewed our understanding of space and time, on the laws of quantum mechanics are based countless everyday objects like transistors, computer chips, and mobile telephones; in particle accelerators we study the components oof matter, and with telescopes we take an ever deeper look in the past of the universe. Taking reference books to these themes at hand, one is overwhelmed by the plethora and complexity of the mathematical formulas. This book of the renowned professor of physics David J. Griffiths id refreshingly different. By means of many illustrative examples and entertaining stories it introducts to the themes and helps the reader also without a large mathematical apparatus to a fundamental understanding of that, about which Einstein, Schroedinger, Heisenberg, and Hubble actually thought and spoke. In each chapter numerous, pedagogically selected examples are completely worked out, in order to fill the matter with life. Moreover the text contains a manifold of problems, which allow the reader to deepen his knowledge and apply immediately. Griffith's ''Revolution in Twentieth Century Physics'' appeals not only to pupils and future studyings of natural sciences, who want to get an appetite for what lies ahead, but also to interested readers, which have already heared in the media from quarks and quanta, the curved space-time, Albert Einstein, and the big bang and now want to understandably know what is at stake in all the excitement.

    @@ What is the green tea? The green tea belongs to the type of non-fermenting tea, with a quality feature of "clear tea infusion with green leaves"; this type of tea has the biggest output in China, and the basic processing procedure of the green tea is divided into three steps: heating, rubbing and drying. According to the different processing technologies, the green tea is divided into fried green tea, baked green tea, steamed green tea and dried green tea. The steamed green tea is to heat the tea by steaming; to heat the tea by pan-frying can be divided into frying, baking and drying, which is called heating by frying, heating by baking and heating by drying. West LakeLongjing, Xinyang Maojian, Bi Luochun, and Sanbeixiang belong to fried green tea; Mount Huang Maofeng, Youjiyuluo, and Luhai pekoe belong to baked green tea;Enshiyulu belongs to steamed green tea.

    Full Text Available Tourism and other culture-based types of small business, which are the leitmotif in the planning of the Europark Ruardi, are becoming the guiding motif in the spatial development of urban centres that are influenced by dynamic transformation processes. The system should build upon the exploitation of both local and regional environmental features. This would encourage the quest for special environmental features, with an emphasis on their conservation, i.e. sustainable development, and connections in a wider context.The Europark is seen as a new strategic point of the Zasavje Region (the region of the central Sava Valley, which is linked to other important points in a region relevant for tourism. Due to the "smallness" of the region and/or the proximity of such points, development can be fast and effective. The interaction of different activities in space yields endless opportunities for users, who choose their own goals and priorities in the use of space. Four theme areas of the Europark area planning are envisaged. The organisation of activities is based on the composition of the mosaic field patterns, where green fields intertwine with areas of different, existing and new, urban functions. The fields of urban and recreation programmes are connected with a network of green areas and walking trails, along which theme park settings are arranged.

  14. Essential shift: Scientific revolution in the 20th century

    Ismay, David K.

    1993-05-01

    With the publishing of Sir Isaac Newton's Principia Mathematica in 1687, a scientific paradigm was established that clearly dominated society for two and half centuries. Many historians of science have identified the Copenhagen interpretation of the quantum theory, formulated c.1927, as having completed a scientific revolution that ended the reign of classical Newtonian science. A rival claim to contemporary scientific revolution, however, has been put forward by Ilya Prigogine and the Brussels school of thermodynamics based on Prigogine's work in non-equilibrium thermodynamics. Using the historical consensus model of scientific revolution first articulated by Thomas S. Kuhn in 1962, this analysis examines the extent to which the Copenhagen interpretation of the quantum theory and the work of IIya Prigogine complete the conceptual, scientific paradigm-shift necessary for a scientific revolution. The resulting historical evidence shows that the Copenhagen interpretation did not complete a paradigm-shift; instead, it was a self-revelation by the scientific community which revealed the essence and fundamental limitations of Newtonian science. Evidence further indicates that the valid claim to scientific revolution in the 20th century lies with the contemporary work of Prigogine and the Brussels school. By abandoning the deterministic, mechanical world-view of the Newtonian paradigm and accepting a new reality of process and irreversible time, Prigogine and his associates have established the foundations for a revolutionary new scientific paradigm.

    2013-01-01

    Full Text Available The 2009 Iranian Presidential Elections represented one of the most contentious displays of the evolving Iranian democracy since the 1979 Islamic Revolution that led to the removal of Mohammad Reza Shah Pahlavi – the nation’s last shah. This tumultuous political event not only exposed a growing rift between the political and religious ruling elite in that country; it also led to the emergence of an opposition movement that would later be known as the Green Revolution. Viewed through a Western political lens, this revolution represented yet another opportunity for the demise of the ruling Iranian Islamic Regime. Recently, some scholars have questioned whether this movement was ever intended to topple the government in the first place, and have argued instead that it represented the beginning of a long-term civil rights push. To better understand why the Green Movement emerged one must first understand what the original intent of the movement was, as well as the political factors that led to its rapid growth. In order to answer these questions, this article will compare and contrast identified similarities and differences between the 1979 Islamic Revolution and 2009 Green Movement in order to isolate the true intent behind this perceived Iranian political revolt.

    Manganese-doped LaMgAl11O19 powder has been prepared by an easy combustion method. Powder x-ray diffraction and scanning electron microscopy have been used to characterize the as-prepared phosphor. The electron paramagnetic resonance (EPR) spectrum of LaMgAl11O19:Mn2+ phosphor exhibits six-line hyperfine structure centered at g ≈ 1.973. The number of spins participating in resonance ( N) and the paramagnetic susceptibility ( χ) for the resonance signal at g ≈ 1.973 have been calculated as a function of temperature. The photoluminescence spectrum exhibits green emission at 516 nm, which is attributed to 4T1 → 6A1 transition of Mn2+ ions. From EPR and luminescence studies, it is observed that Mn2+ ions occupy Mg2+ sites and Mn2+ ions are located at tetrahedral sites in the prepared phosphors.

  18. Energy conundrum, digital revolution and politics

    International Nuclear Information System (INIS)

    The 21st Century will be fundamentally different from the previous one in all aspects of the human life. The world is now facing unprecedented challenges that will determine the fate of the human race as a whole. Our tiny planet is too small to shoulder the weight of six and a half billion energy-needy people and it is too vulnerable to afford violent and confrontational approaches as was the case in the past 20th century. It is also a fact that science opened new horizons before us. Digital Revolution inaugurated a new era in human history. Technology offers tremendous opportunities to overcome new and inherited problems. Sadly, the family of nations is ill-equipped for handling these challenges because the organizational structure of the world society is archaic and inoperative. Or, we live in a geo strategic environment pregnant with dangerous crisis of global significance. Furthermore, the good old days when scientists were heeded respectfully as reliable guides and when scientific facts were accepted as 'veritas' are over. Solid scientific arguments are perceived as cover up stories to defend financial interests of multinational companies. Similarly, confidence in politicians is at its lowest level in several countries. At the center of this puzzle lies a frenetic quest for cleaner, cheaper and more secure energy sources. In such circumstances, the best remedies which may be created by the brightest minds of the world will be tributary to the 'goodwill' of politicians. Or, politicians are under the overwhelming pressure of their respective public opinions who may act according to emotional factors or advices from religion, gossip or ideology. Consequently, 'Societal Issues' will be 'the decisive' factor in shaping the future of 'Emerging Nuclear Energy Systems' as well as nonnuclear technologies. This paper will attempt to identify major elements of this global equation from a political standpoint. One also has to take into account a group of new and powerful

    Full Text Available The environmental benefits for green building from the Leadership in Energy and Environment Design (LEED and Ecology, Energy, Waste, and Health (EEWH rating systems have been extensively investigated; however, the effect of green roofs on the credit-earning mechanisms is relatively unexplored. This study is concerned with the environmental benefits of green roofs with respect to sustainability, stormwater control, energy savings, and water resources. We focused on the relationship between green coverage and the credits of the rating systems, evaluated the credits efficiency, and performed cost analysis. As an example, we used a university building in Keelung, Northern Taiwan. The findings suggest that with EEWH, the proposed green coverage is 50–75%, whereas with LEED, the proposed green coverage is 100%. These findings have implications for the application of green roofs in green building.

    Kvasz, Ladislav

    2014-06-01

    The aim of the paper is to clarify Kuhn's theory of scientific revolutions. We propose to discriminate between a scientific revolution, which is a sociological event of a change of attitude of the scientific community with respect to a particular theory, and an epistemic rupture, which is a linguistic fact consisting of a discontinuity in the linguistic framework in which this theory is formulated. We propose a classification of epistemic ruptures into four types. In the paper, each of these types of epistemic ruptures is illustrated by examples from physics. The classification of epistemic ruptures can be used as a basis for a classification of scientific revolutions and thus for a refinement of our view of the progress of science.

    Dies ist die Geschichte von Einsteins unvollendeter Revolution, einer tiefgreifenden Veränderung unserer Begriffe von Raum, Zeit, Materie und Strahlung. Diese Revolution begann in Einsteins Wunderjahr 1905, wurde durch seine allgemeine Relativitätstheorie aus dem Jahre 1915 fortgesetzt und wirkt in den heutigen Versuchen der Wissenschaft, die Entstehung und das Schicksal des Universums zu verstehen, weiter. Vor dem Hintergrund einer historischen Theorie des wissenschaftlichen Fortschritts wird Einsteins bis heute nicht abgeschlossene Revolution als das Ergebnis einer langfristigen Entwicklung des Wissens verständlich. Anhand der spannenden Geschichte von Einsteins Entdeckungen wird nachvollziehbar, warum große Denker wie Einstein weiter gesehen haben als ihre Vorgänger.

    2015-11-01

    Crisis of replicability is one term that psychological scientists use for the current introspective phase we are in-I argue instead that we are going through a revolution analogous to a political revolution. Revolution 2.0 is an uprising focused on how we should be doing science now (i.e., in a 2.0 world). The precipitating events of the revolution have already been well-documented: failures to replicate, questionable research practices, fraud, etc. And the fact that none of these events is new to our field has also been well-documented. I suggest four interconnected reasons as to why this time is different: changing technology, changing demographics of researchers, limited resources, and misaligned incentives. I then describe two reasons why the revolution is more likely to catch on this time: technology (as part of the solution) and the fact that these concerns cut across social and life sciences-that is, we are not alone. Neither side in the revolution has behaved well, and each has characterized the other in extreme terms (although, of course, each has had a few extreme actors). Some suggested reforms are already taking hold (e.g., journals asking for more transparency in methods and analysis decisions; journals publishing replications) but the feared tyrannical requirements have, of course, not taken root (e.g., few journals require open data; there is no ban on exploratory analyses). Still, we have not yet made needed advances in the ways in which we accumulate, connect, and extract conclusions from our aggregated research. However, we are now ready to move forward by adopting incremental changes and by acknowledging the multiplicity of goals within psychological science.

  13. Analysis of the Rotopod: An all revolute parallel manipulator

    Energy Technology Data Exchange (ETDEWEB)

    Schmitt, D.J.; Benavides, G.L.; Bieg, L.F.; Kozlowski, D.M.

    1998-05-16

    This paper introduces a new configuration of parallel manipulator call the Rotopod which is constructed from all revolute type joints. The Rotopod consists of two platforms connected by six legs and exhibits six Cartesian degrees of freedom. The Rotopod is initially compared with other all revolute joint parallel manipulators to show its similarities and differences. The inverse kinematics for this mechanism are developed and used to analyze the accessible workspace of the mechanism. Optimization is performed to determine the Rotopod design configurations which maximum the accessible workspace based on desirable functional constraints.

    In a recently published article Sydney Brenner argued that the most relevant scientific revolution in biology at his time was the breakthrough of the role of "information" in biology.The fundamental concept that integrates this new biological "information" with matter and energy is the universal Turing machine and von Neumann’s self-reproducing machines.In this article we demonstrate that in contrast to Turing/von Neumann machines living cells can really reproduce themselves.Additionally current knowledge on the roles of noncoding RNAs indicates a radical violation of the central dogma of molecular biology and opens the way to a new revolution in life sciences.

  15. Mobilizing private finance to drive an energy industrial revolution

    International Nuclear Information System (INIS)

    While uptake of renewable energies as a solution to climate change is widely discussed, the issue of public vs. private financing is not yet adequately explored. The debates over the Kyoto Protocol and its successor, culminating in the COP15 Climate Change Conference in Copenhagen in December 2009, maintained a strong preference for public over private financing. Yet it is also clear to most observers that the energy revolution will never happen without the involvement of private finance to drive private investment. In this Viewpoint, we discuss the ways in which private financing could be mobilized to drive the energy industrial revolution that is needed if climate change mitigation is to succeed.

The Crafts–Harley view of the Industrial Revolution is thus rein...

  18. Nonlinear behavior of shells of revolution under cyclic loading.

    Science.gov (United States)

    Levine, H. S.; Armen, H., Jr.; Winter, R.; Pifko, A.

    1973-01-01

    A large deflection elastic-plastic analysis is presented applicable to orthotropic axisymmetric plates and shells of revolution subjected to monotonic and cyclic loading conditions. The analysis is based on the finite-element method. It employs a new higher order, fully compatible, doubly curved orthotropic shell-of-revolution element using cubic Hermitian expansions for both meridional and normal displacements. Both perfectly plastic and strain hardening behavior are considered. Strain hardening is incorporated through use of the Prager-Ziegler kinematic hardening theory, which predicts an ideal Bauschinger effect. Numerous sample problems involving monotonic and cyclic loading conditions are analyzed.

    Nanotechnology, in particular nanophotonics, is proving essential to achieving green outcomes of sustainability and renewable energy at the scales needed. Coatings, composites and polymeric structures used in windows, roof and wall coatings, energy storage, insulation and other components in energy efficient buildings will increasingly involve nanostructure, as will solar cells. Nanostructures have the potential to revolutionize thermoelectric power and may one day provide efficient refrigerant free cooling. Nanomaterials enable optimization of optical, opto-electrical and thermal responses to this urgent task. Optical harmonization of material responses to environmental energy flows involves (i) large changes in spectral response over limited wavelength bands (ii) tailoring to environmental dynamics. The latter includes engineering angle of incidence dependencies and switchable (or chromogenic) responses. Nanomaterials can be made at sufficient scale and low enough cost to be both economic and to have a high impact on a short time scale. Issues to be addressed include human safety and property changes induced during manufacture, handling and outdoor use. Unexpected bonuses have arisen in this work, for example the savings and environmental benefits of cool roofs extend beyond the more obvious benefit of reduced heat flows from the roof into the building.

    Science.gov (United States)

    Sabot, R H

    1992-01-01

    There are hugh gender gaps in school enrollments and in cognitive achievements in rural Pakistan. The findings in this study were that the gaps were due to gender differences in school supply. The gender gap in school achievement could have been reduced by half, by eliminating the gender gap in primary school supply, assuming appropriate treatment of preschool ability. Findings also showed that the gender gap in cognitive skills has increased over time, regardless of the more rapid increase in rural schools for girls. Parents now are just as likely to send a girl child to school as a boy child. The gender gap in school supply has narrowed in recent years, except for the age group 10-14 years. School supply can be increased by operating different shifts in boys' schools or with coeducation, which would reduce the need for large capital investments. Cognitive achievement was related to the quantity of rural schooling a child received. There were variations in school quality that were evident and affected girls' cognitive achievement. High quality schools produced more skilled workers, who have an advantage in income potential. Higher levels of educational attainment were related to higher earnings. The estimated return for increasing expenditures on primary schools to insure high quality and increased cognitive achievement was 11%. The rate of return was higher for higher quality schools than primary or middle schools of average quality. Findings were considered tentative and caveats were indicated. Data were obtained from surveys to a panel of over 800 rural households (over 7000 persons) from villages in Attock and Faisalabad districts of the Punjab; respondents were interviewed 4 times a year. The 10th round of the survey was in spring 1989. Background information was provided on gender differences in schooling and the school system. The models yielded 7 equations on gender differences in the determinants of schooling attainment, conditioned on school supply, and in the production of cognitive achievement. Cohorts in ages 20-24 and 30-44 were analyzed separately. Literacy and preschool reasoning ability tests were conducted to assess abilities. Family background, cost of schooling, school characteristics, and school supply were other variables. Background information was given on the issue of quality, and the conceptual framework for returns on quality improvement and quantity increases. PMID:12318401

  10. The Green Revolution in the World’s Religions: Indonesian Examples in International Comparison

    Directory of Open Access Journals (Sweden)

    Thomas A. Reuter

    2015-10-01

    Full Text Available Similar to progressive political movements, the programs of many religious and spiritual groups today are converging around a shared commitment to address the impending global ecological crisis. The paper explores this convergence by looking at the impact of environmentalist thought on religious discourses in modern Indonesia, the author’s primary research area, and comparing the findings to similar trends elsewhere. The research shows that the environmental movement is causing a transformation in how people understand the character and practical relevance of religion and spirituality today, in Indonesia and beyond. For some eco-spiritual groups, a heightened environmental awareness has become the central tenet of their monistic religious cosmology. The more significant phenomenon, however, is a socially much broader shift toward more science-friendly and contemporary religious cosmologies within the mainstream of major world religions. Islam and Christianity now officially accept that other forms of life have a right to exist and that humanity has a custodial obligation to protect nature. This new outlook rectifies the previous tendency within dualist religions to view nature as vastly inferior and servile to human interests. It simultaneously is a rejection of materialist-scientific cosmologies widely prevalent in late modern consumer societies, which deny any notion of the sacred. This trend in the world’s religions toward a re-evaluation of the cosmological status of humanity in relation to nature and the sacred, I argue, will enhance the prospects of the global environmental movement’s campaign for environmental sustainability.

    Full Text Available There is no innocent literature. Literature is made by love, by hate, by a woman, by an idea, by an injustice, by a hope, to praise or to criticize, but I think literature has never been isolated, pure, detached. [...] Literature cannot escape life and history (Manuel Cofiño Lopez, 1985: 9697. Cofiño Lopezs own literature is no exception. The clear contrast that he presents in The Last Woman and the upcoming battle between magic and reality, ignorance and culture, past and present has a purpose. The author raises the need to end with the old beliefs in order to progress.This inextricable link between magic and reality of the Revolution is present in several novels of the Cuban Revolution. It shows how the two interact, as well as how past and present intermingle. Moreover, we find that magic is present throughout, and is fully compatible with the Revolution. This does not make it erroneous to believe in the stories of Magic Realism. It is a mistake on the part of the revolution and those who write about it for attempting to deny people the magic of their superstitions and beliefs, since magic is not the enemy of progress. They are part of their lives and their culture, and are something that should be respected.

    Full Text Available This paper proposed to determine the Cartesian stiffness matrix and angular deflection analysis of revolute manipulator. The selected manipulator has rigid fixed link, two movable links and two rotary joints with joint stiffness coefficients are taken into account. The kinematic model of revolute joint manipulator has considered as a planar kinematic chain, which is composed by rigid fixed link and two revolute joints with clearance and deformable elements. The calculation of stiffness matrix depends on Jacobian matrix and change of configuration. The rotational joints are modeled as torsion springs with the same stiffness constant. The relative angular deflections are proportional to the actuated torques taken into account. The subject of this paper has to describe a method for stiffness analysis of serial manipulator. In the present work is to derive the stiffness matrix and angular deflection equations in the Robotic manipulator under the consideration of two-link optimum geometry model for rotary joint manipulator. The stiffness values are measured by displacements of its revolute links loaded by force.

    YUAN Hong; ZHANG Xiang-wei

    2005-01-01

    By using the fundamental equations of axisymmetric shallow shells of revolution, the nonlinear bending of a shallow corrugated shell with taper under arbitrary load has been investigated. The nonlinear boundary value problem of the corrugated shell was reduced to the nonlinear integral equations by using the method of Green's function. To solve the integral equations, expansion method was used to obtain Green's function. Then the integral equations were reduced to the form with degenerate core by expanding Green's function as series of characteristic function. Therefore, the integral equations become nonlinear algebraic equations. Newton's iterative method was utilized to solve the nonlinear algebraic equations. To guarantee the convergence of the iterative method, deflection at center was taken as control parameter. Corresponding loads were obtained by increasing deflection one by one. As a numerical example,elastic characteristic of shallow corrugated shells with spherical taper was studied.Calculation results show that characteristic of corrugated shells changes remarkably. The snapping instability which is analogous to shallow spherical shells occurs with increasing load if the taper is relatively large. The solution is close to the experimental results.

New approaches on food production and income generation in the rural areas must be found if this sector of agricultural community is to be assisted. Int...

  16. Industrial revolution - industry 4.0: Are German manufacturing SMEs the first victims of this revolution?

    Directory of Open Access Journals (Sweden)

    Lutz Sommer

    2015-11-01

    Full Text Available Purpose: Industry 4.0 represents a special challenge for businesses in general and for SMEs in particular. The study at hand will examine companies´ awareness, readiness and capability to meet this challenge taking into account the special role of SMEs. Methodology: The results of nine studies dealing with this range of topics are examined in the framework of a systematic review and compared with regard to the objective of the study at hand. Findings: The review showed that, as a rule, there is an awareness concerning the relevance of the topic. The readiness and the capability to meet this challenge exist in parts; however, they strongly depend on the enterprise size. The smaller SMEs are, the higher the risk that they will become victims instead of beneficiaries of this revolution.Originality/value: Considering different studies concerning Industry 4.0 the article gives an insight into the dependence of the Industry 4.0 readiness in reference to the company size. This deepens the knowledge in adaption deficits German SME still have and opens different approaches for further research and action plans.

  17. The quiet revolution: decentralisation and fuel cells; Leise Revolution: Dezentralisierung und Brennstoffzellen

    Energy Technology Data Exchange (ETDEWEB)

    Aschenbrenner, N

    2003-07-01

    This article discusses how major changes in the electricity supply industry can take place in the next few years due to market liberalisation and efforts to reduce the emission of greenhouse gasses. Decentralisation is discussed as being a 'mega-trend' and fuel cells in particular are emphasised as being a suitable means of generating heat and power locally, i.e. where they are needed. Also, the ecological advantages of using natural gas to 'fire' the fuel cell units that are to complement or replace coal-fired or gas-fired combined gas and steam-turbine power stations is discussed. Various types of fuel cell are briefly described. Market developments in the USA, where the power grid is extensive and little reserve capacity is available, are noted. New designs of fuel cell are briefly examined and it is noted that electricity utilities, originally against decentralisation, are now beginning to promote this 'quiet revolution'.

  18. Feeding Revolution: The Black Panther Party and the Politics of Food

    Directory of Open Access Journals (Sweden)

    Mary Potorti

    2014-02-01

    Full Text Available This chapter examines the role of food in the symbolic politics and practical agenda of the Black Panther Party (BPP, founded in the late 1960s in Oakland, California.  Situating hunger and the politics of food at the center of drives for racial justice, it argues that the BPP’s anti-hunger efforts and food-centered campaigns were driven by an implicit understanding of the power of food in battles over racialized definitions of personhood, a forum for both enforcing and resisting hegemonic authority.  From this vantage, the Panthers and their allies in the East Bay community utilized the Party’s popular food programs, specifically its Free Breakfast for School Children Program, as staging grounds to prepare for a revolutionary overthrow of the socio-economic order.  In addition to strengthening the physical bodies of African Americans to ensure their “survival pending revolution,” the food programs served a deeper organizing function by encouraging community members to come together to meet an immediate, practical need and, in doing so, to visualize themselves as part of a larger movement for change.  The Panthers’ subsequent demands for consumer rights and calls for conscientious consumption (both as purchasers and eaters of food highlighted the role of food politics in perpetuating racial injustice while demonstrating the capacity for food-related protest to challenge structures of hunger and patterns of widespread malnourishment.

  19. The rise of China and the time of Africa: Gauging Afro-Sino relations in the light of Confucian philosophy and African ideals

    Directory of Open Access Journals (Sweden)

    Cornel du Toit

    2015-03-01

    Full Text Available The article focuses on Sino-African relations, with specific reference to South Africa. An outline is provided of recent developments as a roadmap for the unfolding of this relationship. The question of whether China’s African interest can be seen as tacit colonisation is discussed. Even if these fears are allayed, the question remains whether the Chinese presence on the continent will make a significant difference to African development. To answer this question, the focus shifts to economic models and the Chinese recipe for economic progress. Confucianism was opposed during the cultural revolution of Mao Zedong, but it now forms the basis for Chinese foreign policy and internal affairs. This is briefly investigated. Some Confucian ideas are related to basic African concepts in an effort to find a common ground in Afro-Chinese relations. The impact of secular Confucianism on African spirituality is discussed.

  20. ORNL and the geographic information systems revolution

    Energy Technology Data Exchange (ETDEWEB)

    Dobson, J.E.; Durfee, R.C.

    1995-12-31

    Explorers from competing teams race to find a mysterious lost city in the heart of Africa. The American team is continuously in touch with its Houston home base through satellite communications. In flight, team leader Karen Ross displays a map of Africa on her computer screen and notes the multicolored lines suggesting different routes from city to city and into the rain forest. Each pathway is accompanied by a precise estimate of travel time to the final destination. Zooming in on the target area, she switches to satellite images and interprets them in shades of blue, purple, and green. At each checkpoint, the team reports its progress and gets a revised estimate of arrival time. Beset by difficulties, the explorers ask for a faster route, but the computer says the alternative is too dangerous. A simulation model with data representing geology, terrain, vegetation, weather, and many other geographic factors predicts local hazards, including the impending eruption of a nearby volcano. The Americans take the faster route anyway and beat the odds. This fictional account of emerging geographic information system (GIS) technologies comes from Michael Crichton`s 1980 novel Congo, which was made into a 1995 movie. The same technologies were highlighted in Clive Cussler`s 1988 techno-thriller Treasure. In reality, GIS technology began more than a quarter of a century ago at key universities and government laboratories in the United States and Canada. Since 1969, Oak Ridge National Laboratory has been among the leading institutions in this diverse, now booming field. GIS has been evolving through new forms and applications ever since.

  1. Measuring the Level of Industrial Green Development and Exploring Its Influencing Factors: Empirical Evidence from China’s 30 Provinces

    Directory of Open Access Journals (Sweden)

    Chaofan Chen

    2016-02-01

    Full Text Available Nowadays, with the green economy becoming mainstream in the world, an industrial revolution as the core of green development has emerged. Based on the empirical evidence from China’s 30 provinces, this study establishes an evaluation index system of China’s industrial green development and applies the analytic hierarchy process to determine the indices’ weights and properties to measure the level of industrial green development in China’s 30 provinces. Then, an empirical study is conducted to explore the relevant factors influencing China’s industrial green development by using the dynamic panel data model and a panel threshold test. The results show that China’s level of industrial green development has the characteristic of typical regional differentiation with a ladder-like distribution from the east and middle to the west, and the eastern region has the highest level on industrial green output, industrial green efficiency and industrial green innovation. Technological progress and innovation can stimulate industrial green development. The impact of environmental regulation and foreign investment on industrial green development presents a nonlinear “N”-type trend, and the positive effects are mainly observed in eastern China. Capital deepening, heavy chemical industries and an unreasonable energy structure are not effective in industrial green development. There is no direct relation between the enterprise scale and industrial green development.

  4. Energy [r]evolution. A sustainable world energy outlook. The three step approach: efficiency/renewables/structure. Energy [R]evolution 2010 at a glance - Key facts and figures

    International Nuclear Information System (INIS)

    A global energy scenario paints a picture of our common future - the picture depicts how the future could unfold. Energy scenarios send important messages on alternative futures to decision makers in political, financial, industrial sectors as well as other stakeholders in the energy market. They paint a picture which can encourage and guide decision makers involved in shaping our energy future. This third edition of the Energy [R]evolution provides a more ambitious and visionary blueprint than the previous two. It demonstrates how the world can get from where we are now, to where we need to be in terms of phasing out fossil fuels, cutting CO2 emissions while ensuring energy security. This phase-out of fossil fuels offers substantial benefits such as independence from world market fossil fuel prices as well as the creation of millions of new green jobs. It also means providing energy to the two billion people currently without reliable access to energy services

  5. [The discovery of blood circulation: revolution or revision?].

    Science.gov (United States)

    Crignon, Claire

    2011-01-01

    The discovery of the principle of blood circulation by William Harvey is generally considered as one of the major events of the "scientific revolution" of the 17th century. This paper reconsiders the question by taking in account the way Harvey's discovery was discussed by some contemporary philosophers and physicians, in particular Fontenelle, who insisted on the necessity of redefining methods and principles of medical knowledge, basing themselves on the revival of anatomy and physiology, and of its consequences on the way it permits to think about the human nature. This return allows us to consider the opportunity of substituting the kuhnian scheme of "structure of scientific revolutions" for the bachelardian concept of "refonte".

    2015-12-01

    We live in the era of Data Revolution, yet we produce data lot faster than we can process them. If not addressed this discrepancy in a timely manner Data Revolution will result in data pollution rather than in economic and intellectual progress.The majority of currently developed and used data processing applications are Von Neumann model based: single, sequential processes that start at a point in time, and advance one step at a time until they are finished. In the current age of cloud computing and multi-core hardware architectures this approach has noticeable limitations in processing large, distributed data. In this paper we describe the CLARA framework that is used to developing Big-data processing applications. We demonstrate the programming methodology and discuss some of the issues for data processing application elasticity, agility and maintenance.

    2013-09-17

    For decades, America has anticipated the transformational impact of clean energy technologies. But even as costs fell and technology matured, a clean energy revolution always seemed just out of reach. Critics often said a clean energy future would "always be five years away." This report focuses on four technology revolutions that are here today. In the last five years they have achieved dramatic reductions in cost and this has been accompanied by a surge in consumer, industrial and commercial deployment. Although these four technologies still represent a small percentage of their total market, they are growing rapidly. The four key technologies this report focuses on are: onshore wind power, polysilicon photovoltaic modules, LED lighting, and electric vehicles.

  8. A new sexual revolution? Critical theory, pornography, and the Internet.

    Science.gov (United States)

    Garlick, Steve

    2011-08-01

    The "sexual revolution" was a central element of North American culture in the 1960s. Today, sex is increasingly central to mainstream culture, in large part due to the Internet, and we might wonder whether we are living through a comparable period of sexual history. In this article, I revisit the work of Herbert Marcuse-the original theorist of the sexual revolution-to ask whether it can contribute to a critical theory of sexuality in the era of digital technology. After outlining Marcuse's theory of the role of Eros in social life, I discuss two pornographic Web sites that combine eroticism and social critique. I argue that Marcuse's work is valuable for its emphasis on the intersection of sex, technology, and capitalist economy, but that it needs to be supplemented by a focus on masculinity and the male body in Internet pornography.

After the first wave of "new growth" theory that addressed the causes of sustained increases in productivity, more attention has been given to an important additional stylized fact: that rapid growth itself is new in historical terms. A radical discontinuity separates thousands of years of by and large stagnant living standards from the industrial era. Increasingly in the last few years, models have attempted to c...

    This article considers the thermoelastic stability of bimetallic shallow shells of revolution. Basic equations are derived from Reissner's non-linear theory of shells by assuming that deformations and rotations are small and that materials are linear elastic. The equations are further specialized for the case of a closed spherical cup. For this case the perturbated initial state is considered and it is shown that only in the cases when the cup edge is free or simply supported buckling under h...

    1988-10-01

    A procedure for cutting surfaces of revolution using a numerically controlled milling machine is described. The procedure differs from conventional techniques in that the curve to be cut is approximated by a circular arc. The errors introduced by the approximation scheme are less than the machining errors. This procedure can be implemented on any machine capable of cutting an arbitrary radius circular arc. It also reduces the number of programming instructions by a factor of ~50. PMID:20539518

    Mexican physicians, faithful to their tradition of honor and patriotism, were present in the military and political events of the great Revolution, the began in 1910 and ended triumphantly in 1917. In the first phase, a Madero supporter and opposed to presidential reelection was doctor Francisco Vázquez Gómez, a specialist in otorhinolaryngology, Professor at the National Medical School and past President of our Academy of Medicine. The second phase of this Revolution, characterized by the struggle against the Huerta dictatorship and then by combats among revolutionary factions, also saw the intervention of many physicians and surgeons, such as senator Belisario Domínguez of Chiapas, a victim of dictatorial oppression. Among them were distinguished academicians such as doctors Rafael Silva of Mexico and Francisco Castillo Nájera of Durango. Likewise devoted nurses were in Carranza's group, while medical students enlisted in Zapata's forces. The last phase of the Revolution was dominated by the activities of the Constituent Congress in Querétaro, which promulgated the New Mexican Constitution. Among 223 elected representatives, 20 were physicians and two pharmacists (10%), who had an excellent participation in the different sessions. The new Constitution, sworn and signed on February 5, 1917, added social guarantees to individual guarantees already established by the Constitution of 1857.

    Full Text Available The direction of the current study is the analysis of the Gulag and Romanian Revolution of 1989 using a psychohistorical investigation, which attempts to provide a plausible psychological explanation of these two events.The relationship between the communist prison space and the situation in '89 can be exploited from other perspectives that emphasize different and nuanced interpretations which can radically change the old historical vision, which focused on documents (archives justifying the official history of power. The conspiratorial silence of prisoners, meaning that inability to confess the suffering in the period before 1989, „exploded“ in the revolution through aggressive manifestations in Timișoara, Bucharest and other cities in the country. In the end we can say that the Revolution was that long-expected time for Romanians to express their negative energies, anguish, disappointment in the paternal authority represented by Nicolae Ceaușescu. In 1989, the soul of the crowd (Gustave Le Bon broke loose after a long period of obedience and humiliation in communist prisons, but also in the huge camp: Romania.

Hungarianémigré organizations formed a "Comité de Ayuda pro Hungría Libre" (Aid Committee for a FreeHungary, coordinating the strategies and actions aimed at providing moral and material supportfor the revolution. Supplementing and aiding these actions were those of the Argentinegovernment and population at large. The government named a special commission for refugees;and there was a tremendous outpour of sympathy and material support for Hungarians amongArgentines, with major press coverage for months to come. Of special importance is the literaryand press output following the revolution. These actions provoked fear and rejection from theEmbassy of the People's Republic of Hungary, and it accused the Argentine government of openlysiding with the émigrés. Upon the Hungarian Foreign Ministry's instructions, the Embassystrongly intensified the espionage on the émigré institutions and its prominent members for years.Relations between émigré organizations and the Hungarian Government remained nonexistent orstrained until the lifting of the Iron Curtain in 1990.

  8. Visions of Revolutions: Microphysics and Cosmophysics in the 1930s

    CERN Document Server

    Kragh, Helge

    2011-01-01

    By 1930, at a time when the new physics based on relativity and quantum theory had reached a state of consolidation, problems of a foundational kind began to abound. Physicists began to speak of a new "crisis" and envisage a forthcoming "revolution" of a scale similar to the one in the mid-1920s. The perceived crisis was an issue not only in microphysics but also in cosmology, where it resulted in ambitious cosmophysical theories that transcended the ordinary methods of physics. The uncertain cognitive situation was, in some circles, associated to the uncertain political and moral situation. Did the problems of foundational physics demand a revolution in thinking that somehow paralleled the political revolutions of the time? I argue that although such ideas were indeed discussed in the 1930s, they were more rhetoric than reality. With the benefit of hindsight one can see that the perceived crisis was only temporary and not significantly related to social or ideological developments in the decade.

As green really has no end point, a teacher's goal should be to teach students to question and consider green. In this article, the author provides several useful metrics to help technology teachers…

    Holbrook, Jarita C; Medupe, R. Thebe; Current Archaeoastronomy and Ethnoastronomy research in Africa

    2008-01-01

    Astronomy is the science of studying the sky using telescopes and light collectors such as photographic plates or CCD detectors. However, people have always studied the sky and continue to study the sky without the aid of instruments this is the realm of cultural astronomy. This is the first scholarly collection of articles focused on the cultural astronomy of Africans. It weaves together astronomy, anthropology, and Africa. The volume includes African myths and legends about the sky, alignments to celestial bodies found at archaeological sites and at places of worship, rock art with celestial imagery, and scientific thinking revealed in local astronomy traditions including ethnomathematics and the creation of calendars. Authors include astronomers Kim Malville, Johnson Urama, and Thebe Medupe; archaeologist Felix Chami, and geographer Michael Bonine, and many new authors. As an emerging subfield of cultural astronomy, African cultural astronomy researchers are focused on training students specifically for do...

  19. The two revolutions in bio-medical research

    Full Text Available In the field of modern medical science, we can identify certain epochs. Some of these will be our concern here, for they offer important insights into the development of modern medicine and offer equally important predictors of where it is heading in the future. In fact they are so important that they qualify to be called nothing less than revolutions.Till the early twentieth century, medicine was an activity dependent on a small privileged elite. This changed by the mid-twentieth century into a vast publicly owned enterprise with enlightened governmental approach, support and funding. One example of this was in the 1940s, sixty five years ago, when Vannever Bush in the US, for example, persuaded the government there to divert resources allocated for the then war effort (World War II to fund basic research in academic institutions. Similarly, in India, what was earlier dependent on the benevolence of zamindars/philanthropists and some missionaries who set up charitable dispensaries/hospitals to serve certain sections of the population was supplemented, and then overtaken, by governmental funding after independence in 1947.This major governmental support to medical science was an important development that led to great advances in medical research and facilities all over. Such funding and consequent blossoming of medical science was nothing less than a revolution, which we can legitimately consider the first revolution in modern medicine.A second revolution was soon to follow four decades later. It was fuelled by a vast upsurge in medical research, training and therapy, with capital pouring in from private enterprise and philanthropy. This revolution is still on. It is aided by efforts like the Bayh-Dole Amendments of 1980 in the US, for example. This epoch making amendment conferred intellectual property rights to institutions and connected scientists even if they had developed their products/inventions with government funding. It was followed

    2015-03-01

    The discovery of fluorescent proteins has been a revolution in cell biology and related sciences because of their many applications, mainly emphasizing their use as cellular markers. The green fluorescent protein (GFP) is one of the most used as it requires no cofactors to generate fluorescence and retains this property into any organism when it is expressed by recombinant DNA techniques, which is a great advantage. In this work, we analyze the emission spectra of recombinant green fluorescent protein in vivo and in vitro exposed to a glow discharge plasma of nitrogen in order to relate electron temperature to fluorescence intensity.

  1. Female genital mutilation in African and African American women's literature

    Directory of Open Access Journals (Sweden)

    Darja Marinšek

    2007-12-01

    Full Text Available The article builds on the existing dispute between African and African American women writers on the competence of writing about female genital mutilation (FGM, and tries to determine the existence and nature of the differences between the writings of these two groups. The author uses comparative analysis of two popular African and African American novels, comparing their ways of describing FGM, its causes and consequences, the level ob objectivity and the style of the narrations.This is followed by a discussion on the reasons for such differences, incorporating a larger circle of both African and African American women authors, at the same time analysing the deviance within the two groups. While the differences between African American writers are not that great, as they mostly fail to present the issue from different points of view, which is often the result of their lack of direct knowledge of the topic, African authors' writing is in itself discovered to be ambivalent and not at all invariable. The reasons for such ambivalence are then discussed in greater context, focusing on the effect of the authors' personal contact with circumcision as well as their knowledge and acceptance of Western values. The author concludes by establishing the African ambivalent attitude towards FGM, which includes different aspects of the issue, as the most significant difference between their and African American writers' description of this practice.

    Full Text Available The events during the “Autumn of People” have created sideration and stupor in the eyes and minds of the Western observers – who least expected the communist breakdown –, and consequently significant problems of interpretation and in deciphering the regime change in East-Central Europe. Clearly, with the “transition to democracy” process, the same observers have expressed disappointment and skepticism regarding the prospects of the countries of ECE unrestrainedly and uncritically embracing the model of Western-type consolidated liberal democracy: many have assessed that the exit from communism was not necessarily synonymous with the “return to Europe” tout court, for the very historical background, socio-economic and cultural preconditions and political conditions were not met so as to generate the complete and definitive triumph of liberal democracy in Europe. The present paper is an attempt at critically examining the regime change in 1988-1989 in East-Central Europe as an exponential case of “postmodern revolution”, following the analysis drawn by S.N. Eisenstadt in late ‘90. Breaking with the paradigm of the “Great Revolutions” (G. Pettee, 1989 lacked the characteristic features of a “classical revolution” (in the French or Russian sense, hence imposing a new species of revolution which was dominantly non-ideological, non-class-based, and non-violent, though achieving its central purpose, i.e. that of effectuating regime change. Concretely, this paper tries to introduce the 1988-1989 regime change in ECE in the general discussion of the defining and the characteristic features of a revolution, drawing extensively on the literature that preceded and followed the anus mirabilis, dedicated to the analysis of revolutions.

  4. Growth in an English population from the Industrial Revolution.

    Mays, S; Brickley, M; Ives, R

    2008-05-01

    The rapid urbanization of the Industrial Revolution in 18th-19th century England presented new health challenges. Our aim is to investigate using English skeletal remains whether the living conditions for an urban working class group in the Industrial Revolution negatively impacted upon their skeletal growth compared with a population from a rural agrarian parish. The Industrial Revolution skeletal material is from St Martin's Churchyard, Birmingham (SMB), West Midlands. It dates primarily from the first half of the nineteenth century when Birmingham was a major manufacturing center. The rural group is from Wharram Percy (WP), North Yorkshire, and dates from 10th-19th century AD. The methodology involves plotting diaphyseal bone lengths versus dental age for subadults. No overall difference was found between the two populations in bone length-for-age among the 2- to 18-year cohort. However the younger parts of the SMB cohort were smaller than at WP; the opposite was true of the older parts of the cohort. Growth rate, as inferred from crosssectional data, appeared greater at SMB than at WP. The only result consistent with expectations is the larger bone dimensions in young children from WP, but this likely reflects prolonged breastfeeding at WP not differences in urban and rural environments. That the deleterious health effects that we know accompanied the major transition in human society from a rural agrarian to an urban industrialized living environment should be little manifest in skeletal endochondral growth data is discouraging for those who would use such methodology to monitor health in earlier populations.

    After the sanitary disaster caused by the first months of the conflict, the Health service of the French armies undertook a true revolution. By 1918, it had become the most efficient of all the opposing armies. At the end of 1914, through the spacing out of the evacuating hospitals within the zone of the armies, the most efficient teams were placed as close as possible to the front. Injured soldiers were categorized at every step of the chain. Technical progress, especially in war surgery, pushed medicine into the moderne era. PMID:25069356

    "Green Food" is a Chinese food production innovation, and has been described as "one of the most successful eco-labelling programs in the world" (Giovannucci, 2005, p.12). Green Food provides a "middle way" between chemical and organic farming. China's development of the Green Food concept resolves issues with both chemical and organic agriculture - for the former by offering reduced pesticide use, and for the latter by providing a stepped pathway for conversion from chemical to organic agric...

  14. Leadership in the African context

    Full Text Available The Western world has always viewed the African continent as plagued by corruption; dictatorship; military coups; rebellious leaders; greediness; misuse of power; and incompetent, politically unstable leaders - in effect, suspicious leaders who undermine their own democracies. This paper analyzes African leadership and its impact by concentrating on three historical eras, namely; the African Religious era; the Christian era, and the era of Globalization. These affected African leadership. In addition, many brilliant minds left the continent in search of greener pastures. A review of these three eras will help us understand how leadership shifted from African values into Western concepts. The role of missionaries lead African people to live with both an African and a Western concept of life. In spite of the above problems, our past leaders did their best in addressing the difficulties they faced during the three eras. African concepts of leadership were often regarded as barbaric and uncultured. Structures were evaluated by Western standards. Due to globalisation, African leaders, through programmes like NEPAD, are going back to basics, drawing on African concepts of unity among its leadership. Effectiveness or life-giving leadership is emerging and empowering villagers/communities in the continent. This type of leadership is innovative and has brought new hope for the continent.

  15. Post Civil War African American History: Brief Periods of Triumph, and Then Despair.

    During Reconstruction, which is often called the most progressive period in American history, African Americans made great strides. By 1868 African American men constituted a majority of registered voters in South Carolina and Mississippi, and by 1870 eighty-five percent of Mississippi's black jurors could read and write. However, Reconstruction was followed by approximately one hundred years of Jim Crow laws, lynching, disenfranchisement, sharecropping, unequal educational resources, terrorism, racial caricatures, and convict leasing. The Civil Rights Revolution finally ended that period of despair, but the era of mass incarceration can be understood as a reaction to the Civil Rights Movement. This article attempts to understand the persistence of racism in the United States from slavery's end until the present. PMID:27108470

    There is a rapid transformation afoot in the rice value chain in Asia. The upstream is changing quickly-farmers are undertaking capital-led intensification and participating in burgeoning markets for land rental, fertilizer and pesticides, irrigation water, and seed, and shifting from subsistence to small commercialized farms; in some areas landholdings are concentrating. Midstream, in wholesale and milling, there is a quiet revolution underway, with thousands of entrepreneurs investing in equipment, increasing scale, diversifying into higher quality, and the segments are undergoing consolidation and vertical coordination and integration. Mills, especially in China, are packaging and branding, and building agent networks in wholesale markets, and large mills are building direct relationships with supermarkets. The downstream retail segment is undergoing a "supermarket revolution," again with the lead in change in China. In most cases the government is not playing a direct role in the market, but enabling this transformation through infrastructural investment. The transformation appears to be improving food security for cities by reducing margins, offering lower consumer rice prices, and increasing quality and diversity of rice. This paper discusses findings derived from unique stacked surveys of all value chain segments in seven zones, more and less developed, around Bangladesh, China, India, and Vietnam.

  17. Intensive groundwater use: a silent revolution that cannot be ignored.

    Science.gov (United States)

    Llamas, M R; Martínez-Santos, P

    2005-01-01

    Over the last decades, agriculture in arid and semi-arid countries has experienced a true "silent revolution" of intensive groundwater use. Millions of independent farmers worldwide have chosen to become increasingly dependent on the reliability of groundwater resources, and as a result their countries have reaped abundant social and economic benefits. Data from several countries shows that groundwater irrigation presents a much greater efficiency, than surface water irrigation systems, thus contributing to fulfil the motto of "more crops and jobs per drop". If this situation is confirmed globally, the usual world water visions have to be reviewed. However, the "silent revolution" has been carried out with scarce control on the part of governmental water agencies, and thus a series of unwanted effects have developed in certain places. While these by no means justify the pervasive "hydromyths" and obsolete paradigms that voice the frailty of groundwater, appropriate management of groundwater resources remains a worldwide challenge. This paper provides an overview of these issues, and concludes with the necessity there is to educate all levels of society on the importance of groundwater and to create bottom-up user associations to manage aquifers as common pool resources.

  18. The Copernican Revolution in Pragmatism? Dewey on Philosophy and Science

    Directory of Open Access Journals (Sweden)

    Tracy Ann P. Llanera

    2009-12-01

    Full Text Available A Copernican revolution heralds a grand renovation of a tradition of knowledge. In science—the discipline from which the concept originates—it aptly connotes a paradigm shift from a previously accepted notion of reality. It is upon this conceptualization that John Dewey wrote: “Kant claimed that he had effected a Copernican revolution in philosophy by treating the world and our knowledge of it from the standpoint of the knowing subject.” For the Enlightenment thinker, traditional philosophy construed a rational system of nature and then borrowed from it the features by which to characterize knowledge. He argued that this “borrowing” of a rational system should not be credited to some outworldy power, but to human reason. Thus, his “revolution” was a shift from theological to human authorship and a placing of the locus of intellect in man as a knowing subject. Kant’s work created a new center in philosophy: that it is the mind that knows by means of an equipment of powers complete within itself and that it merely exercises its capabilities upon an antecedent external material equally complete in itself.

  19. Transient dynamic and inelastic analysis of shells of revolution

    International Nuclear Information System (INIS)

    Advances in the limits of structural use in the aerospace and nuclear power industries over the past years have increased the requirements upon the applicable analytical computer programs to include accurate capabilities for inelastic and transient dynamic analyses. In many minds, however, this advanced capability is unequivocally linked with the large scale, general purpose, finite element programs. This idea is also combined with the view that, therefore, such analyses are prohibitively expensive and should be relegated to the 'last resort' classification. While this, in the general sense, may indeed be the case, if however, the user needs only to analyze structures falling into limited categories, he may find that a variety of smaller special purpose programs are available, which do not put an undue strain upon his resources. One such structural category is shells of revolution. This survey of programs will concentrate upon the analytical tools which have been developed predominantly for shells of revolution. The survey will be subdivided into three parts: a) consideration of programs for transient dynamic analysis, b) consideration of programs for inelastic analysis, and finally, c) consideration of programs capable of dynamic plasticity analysis. In each part, programs based upon finite difference, finite element, and numerical integration methods will be considered. The programs will be compared on the basis of analytical capabilities, and ease of idealization and use. In each part of the survey sample problems will be utilized to exemplify the state-of-the-art.

  20. Transatlantic Discourses of Freedom and Slavery during the English Revolution

    Directory of Open Access Journals (Sweden)

    John Donoghue

    2014-12-01

    Full Text Available Three themes in the discursive history of freedom and slavery during the English Revolution are explored here: the liberty of conscience, the liberty of the body, and the liberty of commerce. In the contests waged to define these liberties, contending factions of revolutionaries refashioned their opponents’ concepts of freedom as forms of bondage. Although explored in discrete fashion by historians, these discourses of religious, bodily, and commercial liberty hardly operated independently from one another.  Indeed, they became increasingly entangled as the Revolution reached its imperial turn (ca. 1649-1655, accompanied as it was by the rise of the slave trade in the West Indies and debates over the nature of “free trade” that circulated between England and the colonies.  Ultimately, to recover the entangled nature of these languages of liberty and their importance in the Revolution’s history of ideas, we must move beyond England itself and into the wider Atlantic world to grasp the material contexts that conditioned the Revolution’s discursive history.

It is to be constantly amazed by the dots that the cultural historian connects, by the different terrains that he leads us through, and by the expansive vistas that he brings into focus. Students interested in almost any aspect of modern and contemporary Chinese culture (from film to fiction to music to dance to bodybuilding will appreciate the wealth of materials and references contained in these two volumes. Similarly, scholars of the Cultural Revolution and the developments since will have much to think about and to address, because what Clark presents here is a richer and more complex narrative of recent Chinese cultural history than has heretofore been packaged or popularized. It is a narrative that underscores the continuing evolution of modern Chinese culture in the twentieth century and beyond.

  2. Mathematical model of deformation of orthotropic reinforced shells of revolution

    2013-08-01

    Full Text Available In recent years there are more and more structures made of composite materials, especially in the form of thin-walled shells, being applied in various fields of technology. When using composite materials such as concrete or fiberglass, reinforcing elements are often placed along the axes of the curvilinear coordinate system of the shell, and in this case, the structure can be considered as orthotropic. There are a lot of papers on the calculation of orthotropic shells, but they do not adequately investigate a number of important factors that influence the stress-strain state of the shell and its stability. In particular, the calculation of reinforced shells does not take into account such factors as in-plane shear, shear and torsional stiffness of ribs, etc. The paper presents the mathematical model of deformation of thin orthotropic shells of revolution, based on the model of Timoshenko – Reissner. The model takes into account the design of reinforcement with the shear and torsional stiffness of the ribs, geometric nonlinearity and also the irregular shape of the shell. Possibility of application of methods and algorithms which are used in the study of isotropic shells is shown. The presented model investigates the stress-strain state and stability of thin orthotropic reinforced shells of revolution more adequate.

    2010-01-01

    Although dissimilarities in cranial and post-cranial morphology among African pygmies groups have been recognized, comparative studies on skull morphology usually pull all pygmies together assuming that morphological characters are similar among them and different with respect to other populations. The main aim of this study is to compare cranial morphology between African pygmies and non-pygmies populations from Equatorial Africa derived from both the Eastern and the Western regions in order to test if the greatest morphological difference is obtained in the comparison between pygmies and non-pygmies. Thirty three-dimensional (3D) landmarks registered with Microscribe in four cranial samples (Western and Eastern pygmies and non-pygmies) were obtained. Multivariate analysis (generalized Procrustes analysis, Mahalanobis distances, multivariate regression) and complementary dimensions of size were evaluated with ANOVA and post hoc LSD. Results suggest that important cranial shape differentiation does occur between pygmies and non-pygmies but also between Eastern and Western populations and that size changes and allometries do not affect similarly Eastern and Western pygmies. Therefore, our findings raise serious doubt about the fact to consider African pygmies as a homogenous group in studies on skull morphology. Differences in cranial morphology among pygmies would suggest differentiation after divergence. Although not directly related to skull differentiation, the diversity among pygmies would probably suggest that the process responsible for reduced stature occurred after the split of the ancestors of modern Eastern and Western pygmies.

    In July 2006, the African Non-Petroleum Producers Association was formed in Senegal, Africa to develop alternative energy sources. It involved 13 of Africa's poorest nations, who joined forces to become global suppliers of biofuels, and some have set mandatory mixing of ethanol into gasoline. Although several biofuel production projects have been launched in western Africa, many of the new projects and plantations have not yet reached maturity due to the time lag between plantation and full-scale production, which is about 6 years. Major projects that could be producing significant quantities of biofuels in the next few years are not yet reflected in production statistics. Although ethanol is not yet being produced in large quantities in Africa, short-term opportunities exist. Countries in the South African Development Community are using molasses from the sugar can industry to produce ethanol. Biodiesel is also not currently produced on a significant scale in western Africa, but several other countries are gaining experience with cotton and palm oil resources, and Jatropha. Biomass residue also represents a large potential for all African countries involved in timber production. Unlike biodiesel production, land use conflicts are not an issue with biomass residue production.
