The study of the health and defense policy reforms in France and the US during the 1990s and 2000s shows that far from disappearing, the influence of state elites is being strategically reconfigured to defend some sector-specific policies. Similarly to those ＂custodians of policy＂ dear to P. Selznick, small groups of elites are gaining expertise within strategic sectors of public policy; they are also making the need to control the cost of public spending their royal battle, in order to safeguard what they see as the crucial role of the public good. In the American cases study, the image of the ＂revolving door＂, which encapsulates the idea of professional mobility back and forth from the private to the public sector, implies a fragmented state, open to external pressures of social groups. We document career and professional trajectories marked by a strong commitment to a given policy area. Circulation, we note, is frequent between these positions in the public sector. While these findings do not in and of themselves allow us to fully assess the influence wielded by these elites, this study identifies the social and political resources and forms of specialization which predispose them to play important roles in shaping public policy. For the past 30 years, the question of varieties of liheralisation has been put forward as an explanatory factor for a wide range of public policies （Schrnidt ＆ Thatcher, 2013; Thelen, 2014）. In this perspective, numerous authors have theorised the dismantling of democratic states and the weakening of public authority that would follow （Suleiman, 2003; Fukuyama, 2004; Bez^s, 2009; Bonneli ＆ Pelletier, 2010; Lodge, 2013）. Research on public policy has focused on the success of neoliberal ideas among European and North American political elites （Pierson, 1994; Prasad, 2006; Fourcade, 2009） on the calling into question of the neo-Keynesian paradigm （Hall, 1986; Crouch, 2011） and on the development of budgetary constraints （Bezbs ＆ Sinr, 2011; Streeck ＆ Schafer, 2013; Blyth, 2013）. Other work emphasises the idea that the effects of economic globalization-reinforced by those of the financial crisis of 2008-have accelerated the weakening of state capacity in western democracies by accelerating the expansion of market relations within national political systems （Streeck ＆ Thelen, 2005; Jabko, 2012）. At the same time, this period has seen renewed interest in national regulation （Lodge, 2011）. Even so, if analysis is limited to the evolution of public policies as a simple functional response to the evolution of the international, financial, or ideological contexts in which they are found, research tends to underestimate the role played by competition among the elite groups involved with their elaboration and their capacity for resilient attachment to the power of public authority. For this reason, the hypothesis of the dismantling of the state, allegedly accelerated by the crisis of 2008, should be revisited.展开更多

It is pathology with a predilection for women. The present clinical case is that of a man with the renal complications of scleroderma and the difficulties of the treatment even in the developed countries like France. In the present case, the management of this disease required a high dose of corticosteroid therapy and extra-renal purification. Early detection of complications through a minimal clinical examination supplemented with paraclinic tests has proved necessary.展开更多

HyFrance3 is a new project that focuses on the economic competitiveness of different steps of the hydrogen chain, from the production to end usage, at the time horizon of 2030 in France. The project is coordinated by CEA with the other partners being： ADEME （co-funding）, AFH2, CNRS, IFP, Air Liquide, EdF, GdF Suez, TOTAL, ALPHEA. The project is divided into 4 sub-projects, that address present and future French hydrogen industrial markets for chemical ＆ refinery uses, the analysis of the interplay between wind energy production and storage of hydrogen for different automotive requirements （refuelling stations, BtL plants, H2/NG mix）, massive hydrogen storage to balance various offer and demand characteristics, and the supply network （pipeline option competitiveness vs. trucked in supply） to distribute hydrogen in a French region for automotive applications. Technical and economical issues, as well as GHG emissions, are addressed.展开更多

The purpose was to report 14 years of experience about the early impact on the quality of life of patients with AD. Methodology: Descriptive retrospective study over 14 years in the geriatric department of Pitié Salpêtrière Hospital, using the activity of daily living, Instrumental activity of daily living, neuropsychological inventory and Hoen Yahr scale evaluated at the time of diagnosis of AD according to the National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer Disease’s and Related Disorders Association diagnostic criteria. Results: A total of 214 exploitable files had been listed. At the moment of diagnosis, the mean age was 82.1 years with extremes 68 to 95 with sex ratio 1.6 in women’s favor. The mean socio-cultural level was 4.9 with extremes about 0 to 7. There was poly pathology with a mean Cumulative Illness Rate Scale = 4.6 with extremes 0 to 16. the mean cognitive status was moderate = 22.5 with extremes 0 to 30. Quality life showed moderate impairment of IADL = 9.2 with extreme 3 to 11 compared to activity of daily living. The activity of daily living was more affected in 68 - 80-year-olds, while poly pathology impacted more on IADL in men. The cognitive impairment was more deficient in IADL when the MMSE test was low. The common disorders at the NPI were psychological, behavioral and psychotic. Conclusion: At the early diagnosis of Alzheimer’s Disease cognitive deficiencies were predominant and influenced on global Instrumental activity and psychological, behavioral disorders.展开更多

Environmental availability of cadmium （Cd）, lead （Pb）, zinc （Zn）, copper （Cu）, and indium （In） in 27 urban soils located around two former Pb and Zn smelters in Northern France were studied by analysing the chemical forms of these metals and evaluating their phytoavailability. These metals were determined using flame or electrothermal absorption atomic spectrometry （FAAS or ETAAS）, depending on their concentration levels. After optimisation of the ETAAS method, characteristic mass of In in water and aqua regia were 9.9 and 18 pg, respectively, showing the high sensitivity of the analytical procedure. Metal partitioning was conducted using a four-step sequential extraction procedure. The results showed that Cd and Zn were mainly in the acid-extractable and reducible forms in the urban soils studied. In contrast, Pb and In were largely in the reducible fraction. However, in some samples, the amount of In extracted in the residual or exchangeable fraction was higher than that in the reducible fraction. Copper was mainly found in the reducible and residual fractions. A pot experiment was conducted in a glasshouse with seven soils （six contaminated and one uncontaminated） and two plant species, ryegrass and lettuce. The results showed transfer of metals from the contaminated soils to the shoots of ryegrass and the edible part of lettuce. The metal bioconcentration factor was in the order of Cd 〉〉 Cu 〉 In 〉 Zn 〉〉 Pb for lettuce leaves, whereas for ryegrass shoots, three orders were found, Cd 〉 Zn 〉 Cu 〉〉 In 〉 Pb, Cd 〉〉 In 〉 Zn 〉 Cu 〉〉Pb, and Zn 〉 Cd 〉 Cu 〉 In 〉〉 Pb, depending on the physico-chemical properties of the soils, such as pH, cation exchange capacity, carbonates, and organic matter. It was established that the metal toxicity was related to the contamination levels and the physico-chemical properties, including pH, organic matter, and in a lesser extent, Ca, Mg, and phosphorus contents, of the soils. However, it was shown that lettuce could grow on soils having high Cd and CaCO3 contents. Cadmium was one of the most available metals while Pb was always the least available in the soils studied.展开更多

After 3-6 days of abstinence, semen samples were collected. Measurements of seminal fluid volume, pH, sperm concentration, total sperm count, motility and detailed morphology of spermatozoa were performed. Sperm parameters were analysed on the entire population and in men with normal total numeration （ 〉~ 40 million per ejaculate）. The whole population demonstrated declining trends in sperm concentration （1.5% per year）, total sperm count （1.6% per year）, total motility （0.4% per year）, rapid motility （5.5% per year） and normal morphology （2.2% per year）. In the group of selected samples with total normal sperm count, the same trends of sperm quality deterioration with time were observed. Our results clearly indicate that the auality of semen decreased in this population over the study period.展开更多

NOx, SO2, O3 and PM10 concentrations were continuously measured over a three-month period, as well as real-time particle size distribution. A rural site located at Cape Gris-Nez, 20 km from Calais, was considered to deduce intrinsic contribution of ship emissions at the harbor city. The average concentrations of the studied species as well as the pattern of the conditional bivariate probability function at the two sites evidenced that in-port shipping, especially during the maneuvering operations, has an important influence on the NOx and SO2 concentrations. The impact of shipping in the harbor of Calais on average concentrations was estimated to 5l% for SO2, 35% for NO, 15% for NO2 and 2% for PM10 in the studied period. Concentration peaks of SO2 and NOx associated with an 03 depletion appeared synchronized with departures and arrivals of ferries. For winds blowing from the harbor, when compared to the background level, the number of particles appeared 10 times higher, with the highest differences in the 30-67 nm and the 109-167 nm size ranges. The average impact of in-port ships on PM10 concentrations was estimated to ＋28.9 μg/m^3 and concerned mainly the PM1 size fraction （40%）. Punctually, PM10 can potentially reach a concentration value close to 100μg/m^3.展开更多

Europe has large areas potentially suitable for poplar forestry and a bioenergy policy that would encourage poplar forestry. In this study I estimated biomass production and carbon sequestration in poplar monoculture plantation and poplar-wheat agroforestry, in the Mediterranean region of France. A single-tree harvesting method was used to estimate biomass and an empirical conversion factor was adopted to calculate sequestered carbon. Total biomass was higher in agroforestry trees(1223 kg tree) than in monoculture plantation trees(1102 kg tree).Aboveground and belowground biomass distributions were similar in both cases(89 and 88% aboveground, and 11 and12% belowground, respectively in agroforestry and monoculture). The partitioning of total biomass in an agroforestry tree in leaves, branch, and trunk(aboveground), and fine roots, medium roots, coarse roots and underground stem(belowground) was 1,22,and 77,and 6,9, 44 and 40%,respectively. Except for branch and trunk, all other compartments were similarly distributed in a monoculture tree.Storage of C was higher in agroforestry trees(612 kg tree)than in monoculture trees(512 kg tree). In contrast, C storage on a per hectare basis was lower in agroforestry(85 Mg ha) than in monoculture(105 Mg ha) due to the lower density of trees per hectare in agroforestry(139 trees in agroforestry vs 204 trees in monoculture). On a per hectare basis, soil C stocks pattern were similar to per tree stocking:They were higher in agroforestry at 330 Mg hathan in monoculture 304 Mg ha. Higher C accumulation by agroforestry has a direct management implication in the sense that expanding agroforestry into agriculture production areas with short rotation and fast growing trees like poplar would encourage quicker and greater C sequestration. This could simultaneously fulfil the requirement of bioenergy plantation in Europe.展开更多

Modern high input energy and resource inefficient agriculture does not address these problems. An efficient food producing system which marries wildlife conservation with resource and energy efficient human food production is needed. This is Ecological Agriculture, modelled on how natural ecosystems work. It is defined as: The establishment and maintenance of a diversified, self-sustaining low input farming system managed to maximize net production without causing large or long term changes to the environment. It must be economically viable, and ethically and aesthetically acceptable [1]. Forty years of research on 4 experimental farms have assessed the practicality of this approach (results previously published). The 5th experimental farm in the mountains of the Pre Alps has completed its 10 years. The results are discussed in relation to the tenets of Ecological Agriculture. The techniques previously developed have allowed the results to fulfil the majority of the demands of efficient ecological agriculture and to produce food for 20 families from the farm’s resources despite the difficult climate, topography and soils. It is shown how energy and resource inefficient the omnivorous animals (poultry and pigs) are, compared to herbivores. The species diversity has increased and the whole farm is a nature reserve. Aesthetic and ethical problems have been addressed with an emphasis on a life of quality for farm animals.展开更多

Research on public policy has focused on the success of neoliberal ideas among European and North American political elites （Pierson, 1994; Prasad, 2006; Fourcade, 2009） on the calling into question of the neo-Keynesian paradigm （Hall, 1986; Crouch, 2011） and on the development of budgetary constraints （Bezbs ＆ Sinr, 2011; Streeck ＆ Schafer, 2013; Blyth, 2013）. Other work emphasises the idea that the effects of economic globalization-reinforced by those of the financial crisis of 2008-have accelerated the weakening of state capacity in western democracies by accelerating the expansion of market relations within national political systems （Streeck ＆ Thelen, 2005; Jabko, 2012）. At the same time, this period has seen renewed interest in national regulation （Lodge, 2011）. Even so, if analysis is limited to the evolution of public policies as a simple functional response to the evolution of the international, financial, or ideological contexts in which they are found, research tends to underestimate the role played by competition among the elite groups involved with their elaboration and their capacity for resilient attachment to the power of public authority. For this reason, the hypothesis of the dismantling of the state, allegedly accelerated by the crisis of 2008, should be revisited.

文摘The Mediterranean Sea is recognized by France as the most important adjacent area and also the gate to Africa,France’s vast sphere of influence beyond the Mediterranean.The political turmoil here since the Arab Spring has begun,especially emergence of a flood of refugees coming to the EU,was a serious problem for France.The current situation of EU,which is shaken over the acceptance of immigrants and refugees,is grave for France,having a strategic pillar which is to raise the own presence in global politics by obtaining the leadership in the EU.France sets out to put the migration and refugee issues to rest,to maintain EU’s political power and to seize the initiative in the EU.This article will analyze such a national strategy of France focusing on the process from Chirac’s administration to Macron’s.
文摘Systemic scleroderma is a rare disease in which visceral manifestations occur, particularly peripheral vascular, digestive, cardiopulmonary and renal. It is pathology with a predilection for women. The present clinical case is that of a man with the renal complications of scleroderma and the difficulties of the treatment even in the developed countries like France. In the present case, the management of this disease required a high dose of corticosteroid therapy and extra-renal purification. Early detection of complications through a minimal clinical examination supplemented with paraclinic tests has proved necessary.

文摘In Quebec,Canada,the public healthcare system offers free medical services.However,patients with spinal pain often encounter long waiting times for specialist appointments and limited physiotherapy coverage.In contrast,private clinics provide expedited care but are relatively scarce and entail out-of-pocket expenses.Once a patient with pain caused by a spinal disorder meets a pain medicine specialist,spinal intervention is quickly performed when indicated,and patients are provided lifestyle advice.Transforaminal epidural steroid injections are frequently administered to patients with radicular pain,and steroid injections are administered on a facet joint to control low back or neck pain.Additionally,medial branch blocks are performed prior to thermocoagulation.France’s universal healthcare system ensures accessibility at controlled costs.It emphasizes physical activity and provides free physical therapy services.However,certain interventions,such as transforaminal and interlaminar epidural injections,are not routinely used in France owing to limited therapeutic efficacy and safety concerns.This underutilization may be a potential cause of chronic pain for many patients.By examining the differences,strengths,and weaknesses of these two systems,valuable insights can be gained for the enhancement of global spinal pain management strategies,ultimately leading to improved patient outcomes and satisfaction.
文摘The HyFrance Group was originally formed in France to support the European project HyWays, by providing （former projects HyFrancel and HyFrance2） the French data and possible hydrogen pathways according to national specificities. HyFrance3 is a new project that focuses on the economic competitiveness of different steps of the hydrogen chain, from the production to end usage, at the time horizon of 2030 in France. The project is coordinated by CEA with the other partners being： ADEME （co-funding）, AFH2, CNRS, IFP, Air Liquide, EdF, GdF Suez, TOTAL, ALPHEA. The project is divided into 4 sub-projects, that address present and future French hydrogen industrial markets for chemical ＆ refinery uses, the analysis of the interplay between wind energy production and storage of hydrogen for different automotive requirements （refuelling stations, BtL plants, H2/NG mix）, massive hydrogen storage to balance various offer and demand characteristics, and the supply network （pipeline option competitiveness vs. trucked in supply） to distribute hydrogen in a French region for automotive applications. Technical and economical issues, as well as GHG emissions, are addressed.
文摘Alzheimer’s disease (AD) is the most common neurodegenerative disease causing an alteration of life quality in the terminal stage. The purpose was to report 14 years of experience about the early impact on the quality of life of patients with AD. Methodology: Descriptive retrospective study over 14 years in the geriatric department of Pitié Salpêtrière Hospital, using the activity of daily living, Instrumental activity of daily living, neuropsychological inventory and Hoen Yahr scale evaluated at the time of diagnosis of AD according to the National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer Disease’s and Related Disorders Association diagnostic criteria. Results: A total of 214 exploitable files had been listed. At the moment of diagnosis, the mean age was 82.1 years with extremes 68 to 95 with sex ratio 1.6 in women’s favor. The mean socio-cultural level was 4.9 with extremes about 0 to 7. There was poly pathology with a mean Cumulative Illness Rate Scale = 4.6 with extremes 0 to 16. the mean cognitive status was moderate = 22.5 with extremes 0 to 30. Quality life showed moderate impairment of IADL = 9.2 with extreme 3 to 11 compared to activity of daily living. The activity of daily living was more affected in 68 - 80-year-olds, while poly pathology impacted more on IADL in men. The cognitive impairment was more deficient in IADL when the MMSE test was low. The common disorders at the NPI were psychological, behavioral and psychotic. Conclusion: At the early diagnosis of Alzheimer’s Disease cognitive deficiencies were predominant and influenced on global Instrumental activity and psychological, behavioral disorders.
文摘Soil contamination by metals from anthropogenic activities （e.g., mining and smelting） is a major concern for the environment and human health. Environmental availability of cadmium （Cd）, lead （Pb）, zinc （Zn）, copper （Cu）, and indium （In） in 27 urban soils located around two former Pb and Zn smelters in Northern France were studied by analysing the chemical forms of these metals and evaluating their phytoavailability. These metals were determined using flame or electrothermal absorption atomic spectrometry （FAAS or ETAAS）, depending on their concentration levels. After optimisation of the ETAAS method, characteristic mass of In in water and aqua regia were 9.9 and 18 pg, respectively, showing the high sensitivity of the analytical procedure. Metal partitioning was conducted using a four-step sequential extraction procedure. The results showed that Cd and Zn were mainly in the acid-extractable and reducible forms in the urban soils studied. In contrast, Pb and In were largely in the reducible fraction. However, in some samples, the amount of In extracted in the residual or exchangeable fraction was higher than that in the reducible fraction. Copper was mainly found in the reducible and residual fractions. A pot experiment was conducted in a glasshouse with seven soils （six contaminated and one uncontaminated） and two plant species, ryegrass and lettuce. The results showed transfer of metals from the contaminated soils to the shoots of ryegrass and the edible part of lettuce. The metal bioconcentration factor was in the order of Cd 〉〉 Cu 〉 In 〉 Zn 〉〉 Pb for lettuce leaves, whereas for ryegrass shoots, three orders were found, Cd 〉 Zn 〉 Cu 〉〉 In 〉 Pb, Cd 〉〉 In 〉 Zn 〉 Cu 〉〉Pb, and Zn 〉 Cd 〉 Cu 〉 In 〉〉 Pb, depending on the physico-chemical properties of the soils, such as pH, cation exchange capacity, carbonates, and organic matter. It was established that the metal toxicity was related to the contamination levels and the physico-chemical properties, including pH, organic matter, and in a lesser extent, Ca, Mg, and phosphorus contents, of the soils. However, it was shown that lettuce could grow on soils having high Cd and CaCO3 contents. Cadmium was one of the most available metals while Pb was always the least available in the soils studied.
文摘Semen from 10 932 male partners of infertile couples was analysed and sperm parameter trends were evaluated at the Reproduction Biology Laboratory of the University Hospital of Marseille （France） between 1988 and 2007. After 3-6 days of abstinence, semen samples were collected. Measurements of seminal fluid volume, pH, sperm concentration, total sperm count, motility and detailed morphology of spermatozoa were performed. Sperm parameters were analysed on the entire population and in men with normal total numeration （ 〉~ 40 million per ejaculate）. The whole population demonstrated declining trends in sperm concentration （1.5% per year）, total sperm count （1.6% per year）, total motility （0.4% per year）, rapid motility （5.5% per year） and normal morphology （2.2% per year）. In the group of selected samples with total normal sperm count, the same trends of sperm quality deterioration with time were observed. Our results clearly indicate that the auality of semen decreased in this population over the study period.

文摘The influence of in-port ship emissions on gases and PM10 concentrations has been estimated in the port city of Calais, northern France, one of the busiest harbor in Europe, with numerous rotations of ferries or roll-on/roll-off cargo in average per day. NOx, SO2, O3 and PM10 concentrations were continuously measured over a three-month period, as well as real-time particle size distribution. A rural site located at Cape Gris-Nez, 20 km from Calais, was considered to deduce intrinsic contribution of ship emissions at the harbor city. The average concentrations of the studied species as well as the pattern of the conditional bivariate probability function at the two sites evidenced that in-port shipping, especially during the maneuvering operations, has an important influence on the NOx and SO2 concentrations. The impact of shipping in the harbor of Calais on average concentrations was estimated to 5l% for SO2, 35% for NO, 15% for NO2 and 2% for PM10 in the studied period. Concentration peaks of SO2 and NOx associated with an 03 depletion appeared synchronized with departures and arrivals of ferries. For winds blowing from the harbor, when compared to the background level, the number of particles appeared 10 times higher, with the highest differences in the 30-67 nm and the 109-167 nm size ranges. The average impact of in-port ships on PM10 concentrations was estimated to ＋28.9 μg/m^3 and concerned mainly the PM1 size fraction （40%）. Punctually, PM10 can potentially reach a concentration value close to 100μg/m^3.

文摘Hydrogen(H2)is an essential vector for freeing our societies from fossil fuels and effectively initiating the energy transition.Offering high energy density,hydrogen can be used for mobile,stationary,or industrial applications of all sizes.This perspective on the crucial role of hydrogen is shared by a growing number of countries worldwide(e.g.,China,Germany,Japan,Republic of Korea,Australia,and United States),which are publishing ambitious roadmaps for the development of hydrogen and fuel cell technologies,supported by substantial financial efforts.
文摘This study's goal is to present a dynamic portrait of the farm-buildings environment in Occitania,in Southern France,in order to better identify the transitions underway in agri-food chains.To this end,we undertook a ter-ritorial diagnosis based on actor statements,using 28 semi-structured interviews across Occitania.This diagnosis was enriched by graphic modelling,which enabled the spatialization of the dynamics described.We show that the process of standardisation of farm buildings prevails in the majority of the territories studied.This phenomenon has intensified in recent years with the development of vast photovoltaic-roofed sheds,accentuating the farm-land conversion and soil sealing.At the same time,in areas with strong environmental,landscape and heritage contexts,a'new adventure in farm buildings'(2022 survey)is taking shape.It is primarily driven by local short food chains,which rely on self-construction,repurposing and refurbishment,the sharing of tools and equipment,and which favour the use and reuse of local resources.This study shows that farm-buildings dynamics crystallise many challenges confronting the reterritorialisation of agriculture and food production.

文摘Wildfire events are increasing globally which may be partly associated with climate change,resulting in significant adverse impacts on local,regional air quality and global climate.In September 2020,a small wildfire(burned area:36.3 ha)event occurred in Souesmes(Loiret-Cher,Sologne,France),and its plume spread out over 200 km on the following day as observed by the MODIS satellite.Based on measurements at a suburban site(~50 km northwest of the fire location)in Orléans and backward trajectory analysis,young wildfire plumes were characterized.Significant increases in gaseous pollutants(CO,CH_(4),N_(2)O,VOCs,etc.)and particles(including black carbon)were found within the wildfire plumes,leading to a reduced air quality.Emission factors,defined as EF(X)=ΔX/ΔCO(where,X represents the target species),of various trace gases and black carbon within the young wildfire plumes were determined accordingly and compared with previous studies.Changes in the ambient ions(such as ammonium,sulfate,nitrate,chloride,and nitrite in the particle-and gasphase)and aerosol properties(e.g.,aerosol water content,aerosol p H)were also quantified and discussed.Moreover,we estimated the total carbon and climate-related species(e.g.,CO_(2),CH_(4),N_(2)O,and BC)emissions and compared them with fire emission inventories.Current biomass burning emission inventories have uncertainties in estimating small fire burned areas and emissions.For instance,we found that the Global Fire Assimilation System(GFAS)may underestimate emissions(e.g.,CO)of this small wildfire while other inventories(GFED and FINN)showed significant overestimation.Considering that it is the first time to record wildfire plumes in this region,related atmospheric implications are presented and discussed.

文摘Poplar is useful in different climates for bioenergy production and carbon sequestration when planted as a single species or in agroforestry. Europe has large areas potentially suitable for poplar forestry and a bioenergy policy that would encourage poplar forestry. In this study I estimated biomass production and carbon sequestration in poplar monoculture plantation and poplar-wheat agroforestry, in the Mediterranean region of France. A single-tree harvesting method was used to estimate biomass and an empirical conversion factor was adopted to calculate sequestered carbon. Total biomass was higher in agroforestry trees(1223 kg tree) than in monoculture plantation trees(1102 kg tree).Aboveground and belowground biomass distributions were similar in both cases(89 and 88% aboveground, and 11 and12% belowground, respectively in agroforestry and monoculture). The partitioning of total biomass in an agroforestry tree in leaves, branch, and trunk(aboveground), and fine roots, medium roots, coarse roots and underground stem(belowground) was 1,22,and 77,and 6,9, 44 and 40%,respectively. Except for branch and trunk, all other compartments were similarly distributed in a monoculture tree.Storage of C was higher in agroforestry trees(612 kg tree)than in monoculture trees(512 kg tree). In contrast, C storage on a per hectare basis was lower in agroforestry(85 Mg ha) than in monoculture(105 Mg ha) due to the lower density of trees per hectare in agroforestry(139 trees in agroforestry vs 204 trees in monoculture). On a per hectare basis, soil C stocks pattern were similar to per tree stocking:They were higher in agroforestry at 330 Mg hathan in monoculture 304 Mg ha. Higher C accumulation by agroforestry has a direct management implication in the sense that expanding agroforestry into agriculture production areas with short rotation and fast growing trees like poplar would encourage quicker and greater C sequestration. This could simultaneously fulfil the requirement of bioenergy plantation in Europe.

文摘In Europe and especially in France,there is a growing enthusiasm for outdoor sports and recreation.In the meantime,the risk of both severe and frequent injuries associated with active pursuits is acknowledged,especially in mountainous areas.The effectiveness of prevention must rely on detailed knowledge of typical circumstances and scenarios but thorough understanding of the mechanisms of accidentality remains limited by the fragmentation of sources and by mostly heterogeneous methodologies.This paper aims at giving insights on victims’profiles,season,location,and circumstances of mountaineering accidents in the French Alps,through the study of rescue interventions data from 2008 to 2018.Thanks to the analysis of the exhaustive database of search and rescue interventions from the French mountain national police force,and while questioning its limitations,we strive to answer two questions:what are the characteristics of the hazardous situations leading to a rescue intervention in mountaineering?Among these situations,what are the characteristics that tend to make them more harmful?
文摘Wildlife conservation must be integrated with energy and resource efficient agriculture for the human population to survive. Modern high input energy and resource inefficient agriculture does not address these problems. An efficient food producing system which marries wildlife conservation with resource and energy efficient human food production is needed. This is Ecological Agriculture, modelled on how natural ecosystems work. It is defined as: The establishment and maintenance of a diversified, self-sustaining low input farming system managed to maximize net production without causing large or long term changes to the environment. It must be economically viable, and ethically and aesthetically acceptable [1]. Forty years of research on 4 experimental farms have assessed the practicality of this approach (results previously published). The 5th experimental farm in the mountains of the Pre Alps has completed its 10 years. The results are discussed in relation to the tenets of Ecological Agriculture. The techniques previously developed have allowed the results to fulfil the majority of the demands of efficient ecological agriculture and to produce food for 20 families from the farm’s resources despite the difficult climate, topography and soils. It is shown how energy and resource inefficient the omnivorous animals (poultry and pigs) are, compared to herbivores. The species diversity has increased and the whole farm is a nature reserve. Aesthetic and ethical problems have been addressed with an emphasis on a life of quality for farm animals.
