  1. Errors in Seismic Hazard Assessment are Creating Huge Human Losses

    The current practice of representing earthquake hazards to the public based upon their perceived likelihood or probability of occurrence is proven now by the global record of actual earthquakes to be not only erroneous and unreliable, but also too deadly! Earthquake occurrence is sporadic and therefore assumptions of earthquake frequency and return-period are both not only misleading, but also categorically false. More than 700,000 people have now lost their lives (2000-2011), wherein 11 of the World's Deadliest Earthquakes have occurred in locations where probability-based seismic hazard assessments had predicted only low seismic low hazard. Unless seismic hazard assessment and the setting of minimum earthquake design safety standards for buildings and bridges are based on a more realistic deterministic recognition of "what can happen" rather than on what mathematical models suggest is "most likely to happen" such future huge human losses can only be expected to continue! The actual earthquake events that did occur were at or near the maximum potential-size event that either already had occurred in the past; or were geologically known to be possible. Haiti's M7 earthquake, 2010 (with > 222,000 fatalities) meant the dead could not even be buried with dignity. Japan's catastrophic Tohoku earthquake, 2011; a M9 Megathrust earthquake, unleashed a tsunami that not only obliterated coastal communities along the northern Japanese coast, but also claimed > 20,000 lives. This tsunami flooded nuclear reactors at Fukushima, causing 4 explosions and 3 reactors to melt down. But while this history of huge human losses due to erroneous and misleading seismic hazard estimates, despite its wrenching pain, cannot be unlived; if faced with courage and a more realistic deterministic estimate of "what is possible", it need not be lived again. An objective testing of the results of global probability based seismic hazard maps against real occurrences has never been done by the

    Full Text Available The intention of a loan loss provision is the anticipation of the loan's expected losses by adjusting the book value of the loan. Furthermore, this loan loss provision has to be compared to the expected loss according to Basel II and, in the case of a difference, liable equity has to be adjusted. This however assumes that the loan loss provision and the expected loss are based on a similar economic rationale, which is only valid conditionally in current loan loss provisioning methods according to IFRS. Therefore, differences between loan loss provisions and expected losses should only result from different approaches regarding the parameter estimation within each model and not due to different assumptions regarding the outcome of the model. The provisioning and accounting model developed in this paper overcomes the before-mentioned shortcomings and is consistent with an economic rationale of expected losses. Additionally, this model is based on a close-to-market valuation of the loan that is in favor of the basic idea of IFRS. Suggestions for changes in current accounting and capital requirement rules are provided.

    Human activity is causing high rates of biodiversity loss. Yet, surprisingly little is known about the extent to which socioeconomic factors exacerbate or ameliorate our impacts on biological diversity. One such factor, economic inequality, has been shown to affect public health, and has been linked to environmental problems in general. We tested how strongly economic inequality is related to biodiversity loss in particular. We found that among countries, and among US states, the number of species that are threatened or declining increases substantially with the Gini ratio of income inequality. At both levels of analysis, the connection between income inequality and biodiversity loss persists after controlling for biophysical conditions, human population size, and per capita GDP or income. Future research should explore potential mechanisms behind this equality-biodiversity relationship. Our results suggest that economic reforms would go hand in hand with, if not serving as a prerequisite for, effective conservation.

  6. Globalization to amplify economic climate losses

    Economic welfare under enhanced anthropogenic carbon emissions and associated future warming poses a major challenge for a society with an evolving globally connected economy. Unabated climate change will impact economic output for example through heat-stress-related reductions in productivity. Since meteorologically-induced production reductions can propagate along supply chains, structural changes in the economic network may influence climate-related losses. The role of the economic network evolution for climate impacts has been neither quantified nor qualitatively understood. Here we show that since the beginning of the 21st century the structural change of the global supply network has been such that an increase of spillover losses due to unanticipated climatic events has to be expected. We quantify primary, secondary and higher-order losses from reduced labor productivity under past and present economic and climatic conditions and find that indirect losses are significant and increase with rising temperatures. The connectivity of the economic network has increased in such a way as to foster the propagation of production loss. This supply chain connectivity robustly exhibits the characteristic distribution of self-organized criticality which has been shifted towards higher values since 2001. Losses due to this structural evolution dominated over the effect of comparably weak climatic changes during this decade. Our finding suggests that the current form of globalization may amplify losses due to climatic extremes and thus necessitate structural adaptation that requires more foresight than presently prevalent.

  8. Economic growth, biodiversity loss and conservation effort.

    This paper investigates the relationship between economic growth, biodiversity loss and efforts to conserve biodiversity using a combination of panel and cross section data. If economic growth is a cause of biodiversity loss through habitat transformation and other means, then we would expect an inverse relationship. But if higher levels of income are associated with increasing real demand for biodiversity conservation, then investment to protect remaining diversity should grow and the rate of biodiversity loss should slow with growth. Initially, economic growth and biodiversity loss are examined within the framework of the environmental Kuznets hypothesis. Biodiversity is represented by predicted species richness, generated for tropical terrestrial biodiversity using a species-area relationship. The environmental Kuznets hypothesis is investigated with reference to comparison of fixed and random effects models to allow the relationship to vary for each country. It is concluded that an environmental Kuznets curve between income and rates of loss of habitat and species does not exist in this case. The role of conservation effort in addressing environmental problems is examined through state protection of land and the regulation of trade in endangered species, two important means of biodiversity conservation. This analysis shows that the extent of government environmental policy increases with economic development. We argue that, although the data are problematic, the implications of these models is that conservation effort can only ever result in a partial deceleration of biodiversity decline partly because protected areas serve multiple functions and are not necessarily designated to protect biodiversity. Nevertheless institutional and policy response components of the income biodiversity relationship are important but are not well captured through cross-country regression analysis.

    2013-01-01

    We extended the U.S. Geological Survey's Prompt Assessment of Global Earthquakes for Response (PAGER) empirical fatality estimation methodology proposed by Jaiswal et al. (2009) to rapidly estimate economic losses after significant earthquakes worldwide. The requisite model inputs are shaking intensity estimates made by the ShakeMap system, the spatial distribution of population available from the LandScan database, modern and historic country or sub-country population and Gross Domestic Product (GDP) data, and economic loss data from Munich Re's historical earthquakes catalog. We developed a strategy to approximately scale GDP-based economic exposure for historical and recent earthquakes in order to estimate economic losses. The process consists of using a country-specific multiplicative factor to accommodate the disparity between economic exposure and the annual per capita GDP, and it has proven successful in hindcast-ing past losses. Although loss, population, shaking estimates, and economic data used in the calibration process are uncertain, approximate ranges of losses can be estimated for the primary purpose of gauging the overall scope of the disaster and coordinating response. The proposed methodology is both indirect and approximate and is thus best suited as a rapid loss estimation model for applications like the PAGER system.

    Brucellosis is a serious public health issue in India. Estimation of economic losses occurring due to brucellosis is required to help formulate prevention and control strategies, but has not been done in India. We estimated economic losses due to brucellosis by sourcing prevalence data from epidemiological surveys conducted in India. Data for livestock populations were obtained from official records. Probability distributions were used for many of the input parameters to account for uncertainty and variability. The analysis revealed that brucellosis in livestock is responsible for a median loss of US $ 3.4 billion (5th-95th percentile 2.8-4.2 billion). The disease in cattle and buffalo accounted for 95.6% of the total losses occurring due to brucellosis in livestock populations. The disease is responsible for a loss of US $ 6.8 per cattle, US$18.2 per buffalo, US $ 0.7 per sheep, US $ 0.5 per goat and US $ 0.6 per pig. These losses are additional to the economic and social consequences of the disease in humans. The results suggest that the disease causes significant economic losses in the country and should be controlled on a priority basis.

  16. Are Global Economic Losses from Natural Hazards Increasing?

    2016-04-01

    Global society has long been influenced by natural hazards, but it has been widely noted that the economic cost of natural hazards has been rising rapidly over recent decades. This upward trend highlights the increasing exposure of the global economy to natural hazards and the need for society to understand the driving factors to help improve the resilience of communities. However disaster risk is driven by a plethora of factors, including population, wealth, land-use, and demographics. Consider also the natural variability in the frequency and severity of events, climate change, and implementation of resilience policies, and it becomes clear that disaster-risk management is a challenging field. To investigate the apparent upward trend in reported annual economic losses from natural disasters, socioeconomic factors known to influence the magnitude of losses must first be accounted for. Adjustment for these factors, known as loss normalisation, aims to estimate the losses sustained if historical events were to impact present day society. We have undertaken a detailed assessment of global economic losses from natural disasters for the period 1995 through 2013. Although the studied time-period is relatively short, expanding the investigated period would not necessarily produce more reliable insights owing to the inherent difficulty in obtaining accurate economic loss estimates for earlier periods and the challenge of finding consistent and reliable sources of socioeconomic data for the normalisation process. The results of the study, presented at a global and regional level, appear to suggest that the main driver of perceived increase in economic losses over the last ~20 years was the development of nations' economies (i.e. increase in population and wealth/GDP) and not in the natural hazards themselves. As populations all over the world migrate into areas of higher natural hazards regions (e.g. coastal areas or floodplain zones) and global wealth continues to

    Taking Zhejiang Province as an example, we use the JOHNES export coefficient model to estimate the total nitrogen (TN) and total phosphorus (TP) load of agricultural planting, livestock and poultry breeding and rural living non-point source in 2009. Based on the protection cost method in environmental economics, we quantitatively assess the economic loss caused by these three types of non-point source nutrient loss. The results show that in TN non-point source load, the load of land for planting accounts for 57.48%, the load of rural living accounts for 30.22%, and the load of livestock and poultry breeding accounts for 12.30%; in TP non-point source load, the load of rural living accounts for 46.18%, the load of livestock and poultry breeding accounts for 29.00%, and the load of land for planting accounts for 24.82%. The economic loss arising from the agricultural non-point source nutrient loss is equivalent to 2.329 424 7 billion yuan per year (the loss from land for planting accounts for 55.46%; the loss from rural living accounts for 31.21%; the loss from livestock and poultry breeding accounts for 13.33%). It indicates that in order to reduce the loss arising from agricultural non-point source nutrient loss, we should pay attention to controlling the land for planting and rural living source.

    Full Text Available INTRODUCTION: Southern Mediterranean countries have experienced a marked increase in the prevalence of obesity whose consequences for gender related health inequities have been little studied. We assessed gender obesity inequalities and their environmental and socio-economic modifiers among Tunisian adults. METHODS: Cross-sectional survey in 2005; national, 3 level random cluster sample of 35-70 years Tunisians (women: n = 2964, men: n = 2379. Overall adiposity was assessed by BMI = weight(kg/height(m(2 and obesity was BMI≥30, WHtR = waist circumference to height ratio defined abdominal obesity as WHtR≥0.6. Gender obesity inequality measure was women versus men Prevalence Proportion Odds-Ratio (OR; models featuring gender x covariate interaction assessed variation of gender obesity inequalities with area (urban versus rural, age, marital status or socio-economic position (profession, education, household income proxy. RESULTS: BMI was much higher among women (28.4(0.2 versus men (25.3(0.1, P<0.0001 as was obesity (37.0% versus 13.3%, OR = 3.8[3.1-7.4], P<0.0001 and abdominal obesity (42.6% versus 15.6%, 4.0[3.3-4.8], P<0.0001. Gender obesity inequalities (women versus men adjusted OR were higher in urban (OR = 3.3[1.3-8.7] than rural (OR = 2.0[0.7-5.5] areas. These gender obesity inequalities were lower for subjects with secondary education or more (OR = 3.3[1.3-8.6], than among those with no schooling (OR = 6.9[2.0-23.3]. They were also lower for those with upper/intermediate profession (OR = 1.4[0.5-4.3] or even employees/workers OR = 2.3[1.0-5.4] than those not professionaly active at all (OR = 3.3[1.3-8.6]. Similar results were observed for addominal obesity. CONCLUSION: The huge overall gender obesity inequities (women much more corpulent than men were higher in urban settings, but lower among subjects of higher education and professional activity.

The analysis provided three key results: a) The production of economic fragility functions from the 1900-2008 events showed very good correlation to the economic loss and cost from earthquakes from 2009-2013, in real-time. This methodology has been extended to other natural disaster types (typhoon, flood, drought). b) The reanalysis of historical earthquake events in order to check associated historical loss and costs versus the expected exposure in terms of intensities. The 1939 Chillan, 1948 Turkmenistan, 1950 Iran, 1972 Managua, 1980 Western Nepal and 1992 Erzincan earthquake events were seen as huge outliers compared with the modelled capital stock and GDP and thus additional studies were undertaken to check the original loss results. c) A worldwide GIS layer database of capital stock (gross and net), GDP, infrastructure age and economic indices over the period 1900-2013 have been created in conjunction with the CATDAT database in order to define correct economic loss and costs.

    Full Text Available Catastrophic events affect various regions of the world with increasing frequency and intensity. The number of catastrophic events and the amount of economic losses is varying in different world regions. Part of these losses is covered by insurance. Catastrophe events in last years are associated with increases in premiums for some lines of business. The article focus on estimating the amount of net premiums that would be needed to cover the total or insured catastrophic losses in different world regions using Bühlmann and Bühlmann-Straub empirical credibility models based on data from Sigma Swiss Re 2010-2016. The empirical credibility models have been developed to estimate insurance premiums for short term insurance contracts using two ingredients: past data from the risk itself and collateral data from other sources considered to be relevant. In this article we deal with application of these models based on the real data about number of catastrophic events and about the total economic and insured catastrophe losses in seven regions of the world in time period 2009-2015. Estimated credible premiums by world regions provide information how much money in the monitored regions will be need to cover total and insured catastrophic losses in next year.

    Full Text Available Brucellosis is an important zoonosis of worldwide distribution. Reliable epidemiologic brucellosis data covering approximately 90% of the cattle population in Brazil have been recently published. Therefore, considering the scarcity of information regarding the economic impact of bovine brucellosis in Brazil, the goal of this study was to estimate economic impact of brucellosis on the Brazilian cattle industry. Several parameters including abortion and perinatal mortality rates, temporary infertility, replacement costs, mortality, veterinary costs, milk and meat losses were considered in the model. Bovine brucellosis in Brazil results in an estimated loss of R$ 420,12 or R$ 226,47 for each individual dairy or beef infected female above 24 months of age, respectively. The total estimated losses in Brazil attributed to bovine brucellosis were estimated to be approximately R$ 892 million (equivalent to about 448 million American dollars. Every 1% increase or decrease in prevalence is expected to increase or decrease the economic burden of brucellosis in approximately 155 million Reais.

  5. Toward economic flood loss characterization via hazard simulation

    Czajkowski, Jeffrey; Cunha, Luciana K.; Michel-Kerjan, Erwann; Smith, James A.

    2016-08-01

    Among all natural disasters, floods have historically been the primary cause of human and economic losses around the world. Improving flood risk management requires a multi-scale characterization of the hazard and associated losses—the flood loss footprint. But this is typically not available in a precise and timely manner, yet. To overcome this challenge, we propose a novel and multidisciplinary approach which relies on a computationally efficient hydrological model that simulates streamflow for scales ranging from small creeks to large rivers. We adopt a normalized index, the flood peak ratio (FPR), to characterize flood magnitude across multiple spatial scales. The simulated FPR is then shown to be a key statistical driver for associated economic flood losses represented by the number of insurance claims. Importantly, because it is based on a simulation procedure that utilizes generally readily available physically-based data, our flood simulation approach has the potential to be broadly utilized, even for ungauged and poorly gauged basins, thus providing the necessary information for public and private sector actors to effectively reduce flood losses and save lives.

    Full Text Available Background: Currently, analyzing the economic losses caused by health problems in population is of particular importance since it stipulates calculations of the volumes invested in healthcare systems in order to improve population’s health. Objective: The aim of our study was to find out economic losses caused by traumatic brain injury (TBI in children. Methods: The given work has utilized governmental statistical reports for Russia, for federal regions as well as for individual subjects. Direct medical expenses (medical services and indirect expenses (losses due to a temporary disability of parents having a sick child were calculated both in general and per patient. Results: Among all the direct medical costs of treatment of children with TBI inpatient care costs account for 85%. In the Central and Volga Federal District accounted for half of nationwide spending in general, brain injury and to provide certain kinds of healthcare. The structure of Russian costs as a result of the incidence of TBI children Moscow accounts for 20%. In Moscow, the cost of treating cases of traumatic brain injury in children is 3.2 times higher than the average for Russia. The resulting calculations of the value of health care costs attributable to a case of child head injury, behind the cost of treatment of the case of a child with head trauma, calculated according to the standards of Russia and the territories. This difference in the whole RF is 23%. Conclusion: The obtained findings have shown that in 2010 in Russia the magnitude of losses caused by TBI incidence in children amounted to 3 billion roubles or 0.008% of the gross product 1.2 billion roubles of which were direct expenses. However, this figure is considerably lower of the real amount; it becomes evident after the analysis of direct medical expenses per one case of pediatric TBI. Our calculations have shown that in Russia and in its regions the amount of expenses per one TBI patient is a quarter less

  10. Evaluation of economic loss from energy-related environmental pollution: a case study of Beijing

    2013-09-01

    With the growth of energy consumption, energy-related environmental pollution has become increasingly serious, which in turn causes enormous economic loss because of public health damage, corrosion of materials, crop yield reduction, and other factors. Evaluating economic loss caused by energy-related environmental pollution can contribute to decision making in energy management. A framework for evaluating economic loss from environmental pollution produced during energy production, transportation, and consumption is proposed in this paper. Regarding SO2, PM10, and solid waste as the main pollutants, economic losses from health damage, materials corrosion, crop yield reduction, and solid waste pollution are estimated based on multiple concentration-response relationships and dose-response functions. The proposed framework and evaluation methods are applied to Beijing, China. It is evident that total economic loss attributable to energy-related environmental pollution fluctuated during 2000-2011 but had a general growth trend, with the highest value reaching 2.3 × 108 CNY (China Yuan) in 2006. Economic loss caused by health damage contributes most to the total loss among the four measured damage types. The total economic loss strongly correlates with the amount of energy consumption, especially for oil and electricity. Our evaluation framework and methods can be used widely to measure the potential impact of environmental pollution in the energy lifecycle.

    2014-04-01

    Full Text Available Aim: To develop a simple mathematical model to assess the losses due to peste des petits ruminants (PPR in small ruminants in India. Materials and Methods: The study was based on cases and deaths in goats and sheep due to PPR from the average combined data on ovine/caprine as published by Government of India for the last 5 years (2008-2012. All possible direct and indirect losses due to the disease, viz. mortality losses, losses due to direct reduction in milk/wool yield, losses due to reproduction failure, body weight losses, treatment costs and opportunity costs, were considered to provide estimate of annual economic losses due to PPR in sheep and goats in India. Based on cases and deaths as reported in sample survey studies, the annual economic loss was also estimated. Results: On the basis of data reported by Government of India, the study has shown average annual economic loss of Rs. 167.83 lacs, of which Rs. 125.67 lacs and Rs. 42.16 lacs respectively are due to the incidence of the disease in goats and sheep. Morbidity losses constituted the greater share of the total loss in both goats and sheep (56.99% and 61.34%, respectively. Among different components of morbidity loss, direct body weight loss was the most significant in both goats and sheep. Based on cases and deaths as reported in sample survey studies, the estimated annual economic loss due to PPR in goats and sheep is Rs. 8895.12 crores, of which Rs. 5477.48 and Rs. 3417.64 crores respectively are due to the disease in goats and sheep. Conclusion: The low economic losses as reported based on Government of India data points towards underreporting of cases and deaths due to the disease. The study thus revealed a significant loss due to PPR in small ruminants on a large scale.

    Most forestry property in Andalusia is privately held. One of the most important possibilities for economic development of rural areas is the use of pasture lands (dehesa in Spanish). During the spring–summer season, swine grazing takes advantage of grasses between the trees, and during winter (harsher times), they use Quercus tree fruit. Swine production has a direct...

    Clinical case series and analysis. The purpose of the present study is to evaluate the advantages and disadvantages of robotic presacral tumor resection compared with conventional open approach. Conventional open approach for huge presacral tumors in the retroperitoneal space often demands excessive hospitalization and poor cosmesis. Furthermore, narrow surgical field sometimes interrupt delicate procedures. Nine patients with huge (diameter >10 cm) presacral tumors underwent surgery. Five patients among them had robotic procedure and the others had open transperitoneal tumor resection. Operation time, blood loss, hospitalization, and complications were analyzed. Robotic presacral tumor resection showed shorter operation time, less bleeding, and shorter hospitalization. Moreover, there was no complication related to abdominal adhesion. Although robotic resection for presacral tumor still has limitations technically and economically, robotic resection for huge presacral tumors demonstrated advantages over open resection specifically for benign neurogenic tumors.

    Indonesia has a high vulnerability towards earthquakes. The low adaptive capacity could make the earthquake become disaster that should be concerned. That is why risk management should be applied to reduce the impacts, such as estimating the economic loss caused by hazard. The study area of this research is West Java. The main reason of West Java being vulnerable toward earthquake is the existence of active faults. These active faults are Lembang Fault, Cimandiri Fault, Baribis Fault, and also Megathrust subduction zone. This research tries to estimates the value of earthquakes economic loss from some sources in West Java. The economic loss is calculated by using HAZUS method. The components that should be known are hazard (earthquakes), exposure (building), and the vulnerability. Spatial modeling is aimed to build the exposure data and make user get the information easier by showing the distribution map, not only in tabular data. As the result, West Java could have economic loss up to 1,925,122,301,868,140 IDR ± 364,683,058,851,703.00 IDR, which is estimated from six earthquake sources with maximum possibly magnitude. However, the estimation of economic loss value in this research is the worst case earthquakes occurrence which is probably over-estimated.

    Full Text Available Subway system is one of the critical infrastructures in a society. In economic optimizations of risk control measures, valuing the loss of life and other financial losses in terms of money on the other hand, could influence the optimal investments in safety. The purpose is to contribute to the implementation of HSE in the transportation system. In this research, a fire risk assessment along with its economic loss estimation in the Direct Current (DC trains and rectifier substation (RS of Tehran subway is implemented. The number of fatalities, the extent of damage on the train equipment, etc., is then calculated in monetary unit. By using Event Tree Analysis (herein ETA, after identification of initiating events through observation, interviews, and evaluation of documents, event tree was constructed for each of them and the probability of multiple scenarios were computed. The scenario with the highest probability of fire in RS, including increased heats in the RTU panels generate a loss of at least 730 Million Rials. Accordingly, the minimum and maximum economic loss caused by fire on DC trains is minimum 510 and 1230 Million Rials, respectively. Conclusion: Given the findings of this study, the financial and human life risks, along with all tangible and intangible losses, which is considerable, the relevant managers must compare investments in safety, with the decrease of calculated economic risks as a result of fire accident in Tehran subway.

    This work estimates the economic losses due to Neospora abortions in the humid pampa region of Argentina.The total dairy and beef cattle population at risk of abortion is 1,771,326 and 9,726,684 head, respectively. In dairy cattle, there was an 8 % risk of experiencing abortion due to a variety of causes, but 16.5 % of them were due to Neospora caninum. The economic losses were estimated at US$1,415 (1,400-1,431) per abortion, which equates to a total loss of US$33,097,221 (15,622,600-119,349,693) for the dairy industry at the humid pampa region of Argentina. In beef cattle, the overall risk of abortion was estimated to be 4.5 % for all pregnancies,whereas 6.7 % are specifically due to N. caninum, with an economic loss of US$440 (range, 150-730) per abortion.This amounts to an annual loss to the beef industry of US$12,903,440 (range, 1,130,700-42,070,630) in the same area. The results of this study show that Neospora infections and thus abortions cause severe economic impacts in the dairy and beef industries in the humid pampa region of Argentina, which is one the most important areas of cattle production in the world [corrected].

  6. Probabilistic Forecasting of Life and Economic Losses due to Natural Disasters

    2014-12-01

    The magnitude of natural hazard events such as hurricanes, tornadoes, earthquakes, and floods are traditionally measured by wind speed, energy release, or discharge. In this study we investigate the scaling of the magnitude of individual events of the 20th and 21stcentury in terms of economic and life losses in the United States and worldwide. Economic losses are subdivided into insured and total losses. Some data sets are inflation or population adjusted. Forecasts associated with these events are of interest to insurance, reinsurance, and emergency management agencies. Plots of cumulative size-frequency distributions of economic and life loss are well-fit by power functions and thus exhibit self-similar scaling. This self-similar scaling property permits use of frequent small events to estimate the rate of occurrence of less frequent larger events. Examining the power scaling behavior of loss data for disasters permits: forecasting the probability of occurrence of a disaster over a wide range of years (1 to 10 to 1,000 years); comparing losses associated with one type of disaster to another; comparing disasters in one region to similar disasters in another region; and, measuring the effectiveness of planning and mitigation strategies. In the United States, life losses due to flood and tornado cumulative-frequency distributions have steeper slopes, indicating that frequent smaller events contribute the majority of losses. In contrast, life losses due to hurricanes and earthquakes have shallower slopes, indicating that the few larger events contribute the majority of losses. Disaster planning and mitigation strategies should incorporate these differences.

  7. Modelling economic losses of historic and present-day high-impact winter windstorms in Switzerland

    2016-03-01

    Full Text Available This study investigates the wind gusts and associated economic loss patterns of high-impact winter windstorms in Switzerland between 1871 and 2011. A novel approach for simulating windstorm-related gusts and losses at regional to local scales is applied to a sample of 84 windstorms. The approach involves the dynamical downscaling of the Twentieth Century Reanalysis (20CR ensemble mean to 3-km horizontal grid size using the Weather Research and Forecasting (WRF model. Economic losses are simulated at municipal level for present-day asset distribution based on the downscaled (parameterised wind gusts at high spatiotemporal resolution using the open-source impact model climada. A comparison with insurance loss data for two recent windstorms (“Lothar” in 1999, “Joachim” in 2011 indicates that the loss simulation allows to realistically simulate the spatial patterns of windstorm losses. The loss amplitude is strongly underestimated for ‘Lothar’, while it is in reasonable agreement for ‘Joachim’. Possible reasons are discussed. Uncertainties concerning the loss simulation arise from the wind gust estimation method applied; estimates can differ considerably among the different methods, in particular over high orography. Furthermore, the quality of the loss simulation is affected by the underlying simplified assumptions regarding the distribution of assets and their susceptibilities to damage. For the whole windstorm sample, composite averages of simulated wind gust speed and loss are computed. Both composites reveal high values for the densely populated Swiss Plateau and lower values for south-eastern Switzerland; metropolitan areas stand out in the loss composite. Eight of the top 10 events concerning the losses simulated for present-day asset distribution and summed over all Swiss municipalities occurred after 1950. It remains uncertain whether this is due to decadal-scale changes of winter windstorms in Switzerland or merely due to a

  8. Economic growth, climate change, biodiversity loss: distributive justice for the global north and south.

    Economic growth-the increase in production and consumption of goods and services-must be considered within its biophysical context. Economic growth is fueled by biophysical inputs and its outputs degrade ecological processes, such as the global climate system. Economic growth is currently the principal cause of increased climate change, and climate change is a primary mechanism of biodiversity loss. Therefore, economic growth is a prime catalyst of biodiversity loss. Because people desire economic growth for dissimilar reasons-some for the increased accumulation of wealth, others for basic needs-how we limit economic growth becomes an ethical problem. Principles of distributive justice can help construct an international climate-change regime based on principles of equity. An equity-based framework that caps economic growth in the most polluting economies will lessen human impact on biodiversity. When coupled with a cap-and-trade mechanism, the framework can also provide a powerful tool for redistribution of wealth. Such an equity-based framework promises to be more inclusive and therefore more effective because it accounts for the disparate developmental conditions of the global north and south.

  9. Economic growth and biodiversity loss in an age of tradable permits.

    2006-08-01

    Tradable permits are increasingly becoming part of environmental policy and conservation programs. The efficacy of tradable permit schemes in addressing the root cause of environmental decline-economic growth--will not be achieved unless the schemes cap economic activity based on ecological thresholds. Lessons can be learned from the largest tradable permit scheme to date, emissions trading now being implemented with the Kyoto Protocol. The Kyoto Protocol caps neither greenhouse gas emissions at a level that will achieve climate stability nor economic growth. If patterned after the Kyoto Protocol, cap-and-trade schemes for conservation will not ameliorate biodiversity loss either because they will not address economic growth. In response to these failures to cap economic growth, professional organizations concerned about biodiversity conservation should release position statements on economic growth and ecological thresholds. The statements can then be used by policy makers to infuse these positions into the local, national, and international environmental science-policy process when these schemes are being developed. Infusing language into the science-policy process that calls for capping economic activity based on ecological thresholds represents sound conservation science. Most importantly, position statements have a greater potential to ameliorate biodiversity loss if they are created and released than if this information remains within professional organizations because there is the potential for these ideas to be enacted into law and policy.

    2009-10-01

    We used socioeconomic models that included economic inequality to predict biodiversity loss, measured as the proportion of threatened plant and vertebrate species, across 50 countries. Our main goal was to evaluate whether economic inequality, measured as the Gini index of income distribution, improved the explanatory power of our statistical models. We compared four models that included the following: only population density, economic footprint (i.e., the size of the economy relative to the country area), economic footprint and income inequality (Gini index), and an index of environmental governance. We also tested the environmental Kuznets curve hypothesis, but it was not supported by the data. Statistical comparisons of the models revealed that the model including both economic footprint and inequality was the best predictor of threatened species. It significantly outperformed population density alone and the environmental governance model according to the Akaike information criterion. Inequality was a significant predictor of biodiversity loss and significantly improved the fit of our models. These results confirm that socioeconomic inequality is an important factor to consider when predicting rates of anthropogenic biodiversity loss.

    Full Text Available Agricultural risk, especially the risk assessment, partition and economic loss estimation of specific and main crops, maize, wheat and rice, is widely touted in China as a means of improving the effective productivity. The main objective of this article is to perform a detailed analysis of the stability and comparative advantage of rice production in 30 provinces on the basis of relative rice production data from 2000 to 2012 in China. The non-parametric information diffusion model based on entropy theory was used to assess rice production risk. Accordingly, we divided the risk level with hierarchical cluster analysis. Then, we calculated the economic loss of rice production by the scenario analysis. The results show that, firstly, the national disaster risk of rice production is at a lower level. Secondly, there are significant differences in the stability, comparative advantage and risk probability of rice production among the 30 provinces. Thirdly, Shanxi province belongs to the high risk zone, 12 provinces belong to the middle risk zone and 17 provinces to the low risk zone. Finally, there is a proportional rate between the economic loss (yield loss and disaster area (yield loss rate of rice production. Therefore, we could obtain some significant policy suggestions.

    2017-07-01

    This paper develops a methodology to assess a group of measures of electrical improvements in distribution systems, starting from the complementation of technical and economic criteria. In order to solve the problem of energy losses in distribution systems, technical and economic analysis was performed based on a mathematical model to establish a direct relationship between the energy saved by way of minimized losses and the costs of implementing the proposed measures. This paper aims at analysing the feasibility of reducing energy losses in distribution systems, by changing existing network conductors by larger crosssection conductors and distribution voltage change at higher levels. The impact of this methodology provides a highly efficient mathematical tool for analysing the feasibility of implementing improvement projects based on their costs which is a very useful tool for the distribution companies that will serve as a starting point to the analysis for this type of projects in distribution systems.

    2017-06-01

    This study investigated, among the Dutch working population, whether job loss during the post-2008 economic crisis is associated with harmful drinking and whether this association is stronger than before the crisis. Repeated cross-sectional data from the Dutch Health Interview Survey 2004-2013 were used to define episodic drinking (≥6 glasses on 1 day ≥1/week) and chronic drinking (≥14 glasses/week for women and ≥21 for men). These data were linked to longitudinal data from tax registries, to measure the experience and duration of job loss during a 5-year working history. Before the crisis, job loss experience and duration were not associated with harmful drinking. During the crisis, job loss for more than 6 months was associated with episodic drinking [OR 1.40 (95% CI 1.01; 1.94)], while current job loss was associated with chronic drinking [OR 1.43 (95% CI 1.03; 1.98)]. These associations were most clear in men and different between the pre-crisis and crisis period (p interaction = 0.023 and 0.035, respectively). The results suggest that economic crises strengthen the potential impact of job loss on harmful drinking, predominately among men.

    Wind erosion is a severe land degradation process in hot arid western India and affects the agricultural production system. It affects crop yield directly by damaging the crops through abrasion, burial, dust deposition etc. and indirectly by reducing soil fertility. In this study, an attempt was made to quantify the indirect impact of wind erosion process on crop production loss and associated economic loss in hot arid ecosystem of India. It has been observed that soil loss due to wind erosion varies from minimum 1.3 t ha-1 to maximum 83.3 t ha-1 as per the severity. Yield loss due to wind erosion was found maximum for groundnut (Arachis hypogea) (5-331 kg ha-1 yr-1), whereas minimum for moth bean (Vigna aconitifolia) (1-93 kg ha-1 yr-1). For pearl millet (Pennisetum glaucum), which covers a major portion of arable lands in western Rajasthan, the yield loss was found 3-195 kg ha-1 yr-1. Economic loss was found higher for groundnut and clusterbean (Cyamopsis tetragonoloba) than rest crops, which are about

Various environmental problems are faced by Semarang involve tidal inundation, land subsidence, and floods during rainy season. This study was conducted to examine the potential economic losses caused by the sea level rise phenomenon. Distribution of inundated area mapped using Digital Elevation Model and Land Subsidence data. The Scenarios of International Panel on Climate Change (2007 sea level rises used to build a model of inundated area that notes by 2030 the rise of sea level rise at 13.4 cm. The inundated map was overlayed with landuse map to calculate the potential economic losses. The results show that the inundated area that occurred in 2030 was 1,718.2 ha with the potential economic losses Rp. 6,130 trillion. With the land subsidence scenario that happen at the area, inundated area increased to 5,171.3 ha with the eonomic potential loss about Rp. 28,724 trillion.

  18. An Assessment of Direct and Indirect Economic Losses of Climatic Extreme Events

    2015-12-01

    Risk of extreme weather events like storms, heat extremes, and floods has already risen due to anthropogenic climate change and is likely to increase further under future global warming. Additionally, the structure of the global economy has changed importantly in the last decades. In the process of globalization, local economies have become more and more interwoven forming a complex network. Together with a trend towards lean production, this has resulted in a strong dependency of local manufacturers on global supply and value added chains, which may render the economic network more vulnerable to climatic extremes; outages of local manufacturers trigger indirect losses, which spread along supply chains and can even outstrip direct losses. Accordingly, in a comprehensive climate risk assessment these inter-linkages should be considered. Here, we present acclimate, an agent based dynamic damage propagation model. Its agents are production and consumption sites, which are interlinked by economic flows accounting for the complexity as well as the heterogeneity of the global supply network. Assessing the economic response on the timescale of the adverse event, the model permits to study temporal and spatial evolution of indirect production losses during the disaster and in the subsequent recovery phase of the economy. In this study, we focus on the dynamic economic resilience defined here as the ratio of direct to total losses. This implies that the resilience of the system under consideration is low if the high indirect losses are high. We find and assess a nonlinear dependence of the resilience on the disaster size. Further, we analyze the influence of the network structure upon resilience and discuss the potential of warehousing as an adaptation option.

    Warming of the climate system and its impacts on biophysical and human systems have been widely documented. The frequency and intensity of extreme weather events have also changed, but the observed increases in natural disaster losses are often thought to result solely from societal change, such as increases in exposure and vulnerability. Here we analyse the economic losses from tropical cyclones in the United States, using a regression-based approach instead of a standard normalization procedure to changes in exposure and vulnerability, to minimize the chance of introducing a spurious trend. Unlike previous studies, we use statistical models to estimate the contributions of socioeconomic factors to the observed trend in losses and we account for non-normal and nonlinear characteristics of loss data. We identify an upward trend in economic losses between 1900 and 2005 that cannot be explained by commonly used socioeconomic variables. Based on records of geophysical data, we identify an upward trend in both the number and intensity of hurricanes in the North Atlantic basin as well as in the number of loss-generating tropical cyclone records in the United States that is consistent with the smoothed global average rise in surface air temperature. We estimate that, in 2005, US$2 to US$14 billion of the recorded annual losses could be attributable to climate change, 2 to 12% of that year's normalized losses. We suggest that damages from tropical cyclones cannot be dismissed when evaluating the current and future costs of climate change and the expected benefits of mitigation and adaptation strategies.

  20. Dependency of U.S. Hurricane Economic Loss on Maximum Wind Speed and Storm Size

    CERN Document Server

    Zhai, Alice R

    2014-01-01

    Many empirical hurricane economic loss models consider only wind speed and neglect storm size. These models may be inadequate in accurately predicting the losses of super-sized storms, such as Hurricane Sandy in 2012. In this study, we examined the dependencies of normalized U.S. hurricane loss on both wind speed and storm size for 73 tropical cyclones that made landfall in the U.S. from 1988 to 2012. A multi-variate least squares regression is used to construct a hurricane loss model using both wind speed and size as predictors. Using maximum wind speed and size together captures more variance of losses than using wind speed or size alone. It is found that normalized hurricane loss (L) approximately follows a power law relation with maximum wind speed (Vmax) and size (R).

    Full Text Available The aim of this paper which reference to Trakya University Hospital draws attention to economic losses of university hospitals due to lack of a system for payment of forensic reports. In this paper, forensic documents of Trakya University Hospital, covering the period January 2003- December 2004, were reviewed. We established the institutions that ask to prepare forensic reports and queries during this period. These institutions were offices of the public prosecutor and court, police, gendarme, and the other institutions (such as management of jails, notary public offices. In 2003 and 2004 Trakya University Hospital forensic reports were 471 and 653, respectively. We established annual rate of increase to the number of prepared forensic reports (39% and unit prices (50-60% between 2003 and 2004. Economic losses of no payment for preparing forensic reports in 2003 and 2004 years have been calculated as 9.647.500.000 TL and 19.420.000.000 TL, respectively. A total economic loss for two years was 29.067.500.000 TL. As a conclusion, the prices of contributing forensic expertise services by university for medicolegal cases must be measured according to price list of Council of Forensic Medicine. Managements of the universities with the help of Council of Higher Education should apply to Ministry of Finance for solving this problem. Key words: Forensic report, cost, university hospital

    To predict the economic loss of crops caused by acid rain, we used partial least squares (PLS) regression to build a model of single dependent variable-the economic loss calculated with the decrease in yield related to the pH value and levels of Ca2+, NH4+, Na+, K+, Mg2+, SO42-, NO3-, and Cl- in acid rain. We selected vegetables which were sensitive to acid rain as the sample crops, and collected 12 groups of data, of which 8 groups were used for modeling and 4 groups for testing. Using the cross validation method to evaluate the performace of this prediction model indicates that the optimum number of principal components was 3, determined by the minimum of prediction residual error sum of squares, and the prediction error of the regression equation ranges from-2.25% to 4.32%. The model predicted that the economic loss of vegetables from acid rain is negatively corrrelated to pH and the concentrations of NH4+, SO42-, NO3-, and Cl- in the rain, and positively correlated to the concentrations of Ca2+, Na+, K+ and Mg2+. The precision of the model may be improved if the non-linearity of original data is addressed.

    To demonstrate the feasibility of laparoscopic management of a huge cervical myoma. Step-by-step video demonstration of the surgical procedure (Canadian Task Force classification III-C). Uterine myoma is the most common benign neoplasm of the female reproductive tract, with an estimated incidence of 25% to 30% at reproductive age [1,2]. Patients generally have no symptoms; however, those with such symptoms as severe pelvic pain, heavy uterine bleeding, or infertility may be candidates for surgery. The traditional management is surgery; however, uterine artery embolization or hormonal therapy using a gonadotropin-releasing hormone agonist or a selective estrogen receptor modulator should be preferred as the medical approach. Surgical management should be performed via laparoscopy or laparotomy; however, the use of laparoscopic myomectomy is being debated for patients with huge myomas. Difficulties in the excision, removal, and repair of myometrial defects, increased operative time, and blood loss are factors keeping physicians away from laparoscopic myomectomy [1,2]. A 40-year-old gravida 0, para 0 woman was admitted to our clinic with complaints of chronic pelvic pain, dyspareunia, and infertility. Her health history was unremarkable. Ultrasonographic examination revealed a 14 × 10-cm myoma in the cervical region. On bimanual examination, an immobile solid mass originating from the uterine cervix and filling the pouch of Douglas was palpated. The patient was informed of the findings, and laparoscopic myomectomy was recommended because of her desire to preserve her fertility. Abdominopelvic examination revealed a huge myoma filling and enlarging the cervix. Myomectomy was performed using standard technique as described elsewhere. A transverse incision was made using a harmonic scalpel. The myoma was fixed with a corkscrew manipulator and enucleated. Once bleeding was controlled, the myoma bed was filled with Spongostan to prevent possible bleeding from leakage

    Full Text Available The present study was conducted to investigate the prevalence of various reproductive disorders and to estimate the economic losses due to genital prolapse in buffaloes in Sir Shamir area of District Faisalabad, Pakistan. The survey was conducted in 8 villages during the 12 months period from June 2005 to May 2006 and the data from 400 farmers (50 farmers from each village were collected. The total buffalo population of this area was 7,785, out of which 2,135 (27.42% animals were included in the study. The overall prevalence of reproductive disorders in buffaloes was recorded as 46.18%. Among all the reproductive disorders, repeat breeding showed the highest prevalence (15.69%, followed by anestrous (9.74%, genital prolapse (7.73%, abortion (5.99%, retained placenta (2.58%, uterine torsion (2.39% and dystocia (2.06%. The total economic losses due to genital prolapse in buffaloes in eight villages during the period of study were estimated to be Rs. 4,59,500/- Among these, the highest losses were due to mortality of dam (39.17%, followed by milk losses (25.14%, service charges (21.33% and medicine cost (14.36%. Thus, repeat breeding, anoestrus and genital prolapse seem to be the major reproductive problems in buffaloes in the study area.

  5. Physically-based Assessment of Tropical Cyclone Damage and Economic Losses

    2012-12-01

    Estimating damage and economic losses caused by tropical cyclones (TC) is a topic of considerable research interest in many scientific fields, including meteorology, structural and coastal engineering, and actuarial sciences. One approach is based on the empirical relationship between TC characteristics and loss data. Another is to model the physical mechanism of TC-induced damage. In this talk we discuss about the physically-based approach to predict TC damage and losses due to extreme wind and storm surge. We first present an integrated vulnerability model, which, for the first time, explicitly models the essential mechanisms causing wind damage to residential areas during storm passage, including windborne-debris impact and the pressure-debris interaction that may lead, in a chain reaction, to structural failures (Lin and Vanmarcke 2010; Lin et al. 2010a). This model can be used to predict the economic losses in a residential neighborhood (with hundreds of buildings) during a specific TC (Yau et al. 2011) or applied jointly with a TC risk model (e.g., Emanuel et al 2008) to estimate the expected losses over long time periods. Then we present a TC storm surge risk model that has been applied to New York City (Lin et al. 2010b; Lin et al. 2012; Aerts et al. 2012), Miami-Dade County, Florida (Klima et al. 2011), Galveston, Texas (Lickley, 2012), and other coastal areas around the world (e.g., Tampa, Florida; Persian Gulf; Darwin, Australia; Shanghai, China). These physically-based models are applicable to various coastal areas and have the capability to account for the change of the climate and coastal exposure over time. We also point out that, although made computationally efficient for risk assessment, these models are not suitable for regional or global analysis, which has been a focus of the empirically-based economic analysis (e.g., Hsiang and Narita 2012). A future research direction is to simplify the physically-based models, possibly through

  6. Implementation and adaptation of a macro-scale methodology to calculate direct economic losses

    As one of the 195 member countries of the United Nations, Germany signed the Sendai Framework for Disaster Risk Reduction 2015-2030 (SFDRR). With this, though voluntary and non-binding, Germany agreed to report on achievements to reduce disaster impacts. Among other targets, the SFDRR aims at reducing direct economic losses in relation to the global gross domestic product by 2030 - but how to measure this without a standardized approach? The United Nations Office for Disaster Risk Reduction (UNISDR) has hence proposed a methodology to estimate direct economic losses per event and country on the basis of the number of damaged or destroyed items in different sectors. The method bases on experiences from developing countries. However, its applicability in industrial countries has not been investigated so far. Therefore, this study presents the first implementation of this approach in Germany to test its applicability for the costliest natural hazards and suggests adaptations. The approach proposed by UNISDR considers assets in the sectors agriculture, industry, commerce, housing, and infrastructure by considering roads, medical and educational facilities. The asset values are estimated on the basis of sector and event specific number of affected items, sector specific mean sizes per item, their standardized construction costs per square meter and a loss ratio of 25%. The methodology was tested for the three costliest natural hazard types in Germany, i.e. floods, storms and hail storms, considering 13 case studies on the federal or state scale between 1984 and 2016. Not any complete calculation of all sectors necessary to describe the total direct economic loss was possible due to incomplete documentation. Therefore, the method was tested sector-wise. Three new modules were developed to better adapt this methodology to German conditions covering private transport (cars), forestry and paved roads. Unpaved roads in contrast were integrated into the agricultural and

    Mycotoxins, toxins produced by fungi that colonize food crops, can pose a heavy economic burden to the United States corn industry. In terms of economic burden, aflatoxins are the most problematic mycotoxins in US agriculture. Estimates of their market impacts are important in determining the benefits of implementing mitigation strategies within the US corn industry, and the value of strategies to mitigate mycotoxin problems. Additionally, climate change may cause increases in aflatoxin contamination in corn, greatly affecting the economy of the US Midwest and all sectors in the US and worldwide that rely upon its corn production. We propose two separate models for estimating the potential market loss to the corn industry from aflatoxin contamination, in the case of potential near-future climate scenarios (based on aflatoxin levels in Midwest corn in warm summers in the last decade). One model uses probability of acceptance based on operating characteristic (OC) curves for aflatoxin sampling and testing, while the other employs partial equilibrium economic analysis, assuming no Type 1 or Type 2 errors, to estimate losses due to proportions of lots above the US Food and Drug Administration (FDA) aflatoxin action levels. We estimate that aflatoxin contamination could cause losses to the corn industry ranging from $52.1 million to $1.68 billion annually in the United States, if climate change causes more regular aflatoxin contamination in the Corn Belt as was experienced in years such as 2012. The wide range represents the natural variability in aflatoxin contamination from year to year in US corn, with higher losses representative of warmer years. PMID:26807606

    Cystic ehinococcosis (CE) caused by Echinococcus granulosus remains a neglected zoonotic disease despite its considerable human and animal health concerns. This is the first systematic analysis of the livestock and human related economic losses due to cystic echinococcosis in India. Data about human cases were obtained from a tertiary hospital. Human hydatidosis cases with and without surgical interventions were extrapolated to be 5647 and 17075 per year assuming a total human population of 1210193422 in India. Data about prevalence of hydatid cysts in important food producing animals were obtained from previously published abattoir based epidemiological surveys that reported a prevalence of 5.39% in cattle, 4.36% in buffaloes, 3.09% in pigs, 2.23% in sheep and 0.41% in goats. Animal population data were sourced from the latest census conducted by the Department of Animal Husbandry, Dairying and Fisheries, India. Other input parameters were obtained from published scientific literature. Probability distributions were included for many input values to account for variability and uncertainty. Sensitivity analyses were conducted to evaluate the effect of important parameters on the estimated economic losses. The analysis revealed a total annual median loss of Rs. 11.47 billion (approx. US $ 212.35 million). Cattle and buffalo industry accounted for most of the losses: 93.05% and 88.88% of the animal and total losses, respectively. Human hydatidosis related losses were estimated to be Rs. 472.72 million (approx. US $ 8.75 million) but are likely to be an under-estimate due to under-reporting of the disease in the country. The human losses more than quadrupled to Rs. 1953 million i.e. approx. US $ 36.17 million, when the prevalence of human undiagnosed cases was increased to 0.2% in the sensitivity analyses. The social loss and psychological distress were not taken into account for calculating human loss. The results highlight an urgent need for a science based policy

    Recent theory predicts harsh and stochastic conditions to generally promote the evolution of cooperation. Here, we test experimentally whether stochasticity in economic losses also affects the value of reputation in indirect reciprocity, a type of cooperation that is very typical for humans. We used a repeated helping game with observers. One subject (the "Unlucky") lost some money, another one (the "Passer-by") could reduce this loss by accepting a cost to herself, thereby building up a reputation that could be used by others in later interactions. The losses were either stable or stochastic, but the average loss over time and the average efficiency gains of helping were kept constant in both treatments. We found that players with a reputation of being generous were generally more likely to receive help by others, such that investing into a good reputation generated long-term benefits that compensated for the immediate costs of helping. Helping frequencies were similar in both treatments, but players with a reputation to be selfish lost more resources under stochastic conditions. Hence, returns on investment were steeper when losses varied than when they did not. We conclude that this type of stochasticity increases the value of reputation in indirect reciprocity.

    Full Text Available Aim: To analyze the factors associated with morbidity and mortality rates as well as to evaluate economic losses due to important diseases of bovines, viz. mastitis, HS and surra in Purvanchal Region of Uttar Pradesh. Materials and Methods: A sample of 300 livestock owners were selected from each of five divisions of Purvanchal region of the state of Uttar Pradesh using multistage stratified sampling with simple random sampling without replacement at village level. The morbidity, mortality and case fatality rates due to different diseases were determined using standard statistical indices. Association between cattle morbidity and mortality rates and different factors was calculated by χ2 Test. The total economic loss due to diseases in bovines was worked out as sum of mortality loss, loss in milk yield and cost of treatment of affected animals. Results: The overall morbidity rates of mastitis, HS and surra in cattle and buffaloes were 15.5%, 7.1% and 5.3%, respectively. The mortality and case fatality due to HS was found higher in the young calves as compared to the adults in case of both buffaloes and cattle. Mortality and case fatality due to surra was greater in the adult animals as compared to the younger ones in case of both buffaloes and cattle. Total losses due to mastitis per lactation in ND cow, CB cow and buffalo were INR 868.34, INR 1, 314.10 and INR 1, 272.36, respectively. Total losses due to HS per animal in ND cows, CB cows and buffaloes were INR 2, 355.78, INR 3, 228.52 and INR 4, 262.57, respectively. Total losses due to surra per animal in ND cow, CB cow and buffalo were INR 3, 328.18, INR 6, 193 and INR 9, 872.33, respectively. Conclusion: The study thus revealed significant losses due to diseases in large ruminants on. There is thus ample scope for preventive measures to control the disease bovines.

    Full Text Available This paper analyses the efficient use of pesticides by internalizing the costs of externality, and estimates the monetary value of welfare loss. The benefit of pesticide use is estimated using a production function, and the economic value of the adverse impact on human health and the environment are represented by a health cost and consumers’ willingness to pay for a kg reduction in pesticide use. To estimate the benefit of pesticides, the paper uses farm level crosssectional and time series data set on rice production. The results indicate low efficiency of using pesticide. This means that totally banning the use of pesticides is economically inefficient.

A 35-year-old woman was admitted to our clinic with complaints of chronic pelvic pain and heavy menstrual bleeding. Her medical history included multiple hospitalizations for blood transfusions, along with a recently measured hemoglobin level of 9.5 g/dL and a hematocrit value of 29%. She had never been married and had no children. Pelvic ultrasonography revealed a 12 × 10-cm uterine myoma located on the posterior side of the corpus uteri and protruding through to the cervical channel. This was a huge intramural submucous myoma in close proximity to the endometrial cavity and spreading through the myometrium. On vaginal examination, the myoma was found to extend into the vagina through the cervical channel. Laparoscopic myomectomy was planned because of the patient's desire for fertility preservation. Abdominopelvic exploration revealed a huge myoma filling the posterior side of the corpus uteri and

    In this paper, multiobjective economic load dispatch (MELD) problem considering generation cost and transmission losses has been formulated using priority goal programming (PGP) technique. In this formulation, equality constraint has been considered by inclusion of penalty parameter K. It has been observed that fixing its value to 1,000 keeps the equality constraint within limits. The non-inferior set for IEEE 5, 14 and 30-bus systems has been generated by Particle Swarm Optimization (PSO) technique. The best compromise solution has been chosen as the one which gives equal percentage saving for both the objectives.

    Windstorms can cause significant financial damage and they rank among the most hazardous meteorological hazards in Switzerland. Risk associated with windstorms involves the combination of hazardous weather conditions, such as high wind gust speeds, and socio-economic factors, such as the distribution of assets as well as their susceptibilities to damage. A sophisticated risk assessment is important in a wide range of areas and has benefits for e.g. the insurance industry. However, a sophisticated risk assessment needs a large sample of storm events for which high-resolution, quantitative meteorological and/or loss data are available. Latter is typically an aggravating factor. For present-day windstorms in Switzerland, the data basis is generally sufficient to describe the meteorological development and wind forces as well as the associated impacts. In contrast, historic windstorms are usually described by graphical depictions of the event and/or by weather and loss reports. The information on historic weather events is overall sparse and the available historic weather and loss reports mostly do not provide quantitative information. It has primarily been the field of activity of environmental historians to study historic weather extremes and their impacts. Furthermore, the scarce availability of atmospheric datasets reaching back sufficiently in time has so far limited the analysis of historic weather events. The Twentieth Century Reanalysis (20CR) ensemble dataset, a global atmospheric reanalysis currently spanning 1871 to 2012, offers potentially a very valuable resource for the analysis of historic weather events. However, the 2°×2° latitude-longitude grid of the 20CR is too coarse to realistically represent the complex orography of Switzerland, which has considerable ramifications for the representation of smaller-scale features of the surface wind field influenced by the local orography. Using the 20CR as a starting point, this study illustrates a method to

    While preparing an anticancer drug, even if it is an expensive molecular target drug, the remainder is not divided and saved for use in other patients; instead, it is discarded, resulting in waste of medical resources. In this study, we examined the economic loss in terms of medical costs by calculating the discarded amounts of 12 commonly used molecular target drugs at Ogaki Municipal Hospital, Japan between January 2012 and December 2014. We found, on average, that drugs valued at ¥ 52,593,182 were discarded annually. In particular, the discarded amounts of relatively expensive drugs, such as bevacizumab, bortezomib, and rituximab, were valued at ¥ 16,646,300, ¥ 15,866,289, and ¥ 8,401,324, respectively. Among these, the average amount of waste per administration of bortezomib was particularly expensive, at a cost of ¥ 67,325. Bortezomib is a commonly used treatment, resulting in excessive cumulative discarded cost. In an effort to save cost, we should consider using small capacity standard injections. Development of a simulation that used the remaining drug contents from only 1 day showed that bevacizumab alone accounts for an average cost saving of ¥1 2,542,191(75.3%) per year. This study suggests that effectively utilizing the remaining drug contents would ensure efficient use of medical resources, thereby reducing economic losses.

    The number of surface water pollution accidents (abbreviated as SWPAs) has increased substantially in China in recent years. Estimation of economic losses due to SWPAs has been one of the focuses in China and is mentioned many times in the Environmental Protection Law of China promulgated in 2014. From the perspective of water bodies' functions, pollution accident damages can be divided into eight types: damage to human health, water supply suspension, fishery, recreational functions, biological diversity, environmental property loss, the accident's origin and other indirect losses. In the valuation of damage to people's life, the procedure for compensation of traffic accidents in China was used. The functional replacement cost method was used in economic estimation of the losses due to water supply suspension and loss of water's recreational functions. Damage to biological diversity was estimated by recovery cost analysis and damage to environmental property losses were calculated using pollutant removal costs. As a case study, using the proposed calculation procedure the economic losses caused by the major Songhuajiang River pollution accident that happened in China in 2005 have been estimated at 2263 billion CNY. The estimated economic losses for real accidents can sometimes be influenced by social and political factors, such as data authenticity and accuracy. Besides, one or more aspects in the method might be overestimated, underrated or even ignored. The proposed procedure may be used by decision makers for the economic estimation of losses in SWPAs. Estimates of the economic losses of pollution accidents could help quantify potential costs associated with increased risk sources along lakes/rivers but more importantly, highlight the value of clean water to society as a whole.

    Trichobezoar is a rare clinical entity in which a ball of hair amasses within the alimentary tract. It can either be found as isolated mass in the stomach or may extend into the intestine. Trichobezoars mostly occur in young females with psychiatric disorders such as trichophagia and trichotillomania. Authors present a giant trichobezoar in an 18year old female presented with complaints of upper abdominal mass, epigastric area pain, anorexia and weight loss. The patient underwent trans-abdominal ultrasonography (USG), Computed tomography (CT), upper gastrointestinal endoscopy and subsequently laparotomy. USG was inconclusive due to non-specific findings. It revealed a thick echogenic layer with posterior dirty shadowing extending from the left sub-diaphragmatic area to the right sub hepatic region obscuring the adjacent structures. Abdominal CT images revealed a huge, well defined, multi-layered, heterogeneous, solid appearing, non-enhancing mass lesion in the gastric lumen extending from the gastric fundus to the pyloric canal. An endoscopic attempt was performed for removal of this intraluminal mass, but due to its large size, and hard nature, the endoscopic removal was unsuccessful. Finally the large trichobezoar was removed with open laparotomy. Trichobezoars should be suspected in young females with long standing upper abdominal masses; as the possibility of malignancy is not very common in this age group. While USG is inconclusive, trichobezoar can be accurately diagnosed with CT. In patient with huge trichobezoar, laparotomy can be performed firstly because of big size and location of mass, and psychiatric recommendation should be made to prevent relapse of this entity.

    Land degradation is a consequence stemming from both natural processes and social economic activities. On the bases of analyzing general situation of agricultural land degradation in China, the monetary estimating methods such as market value method and shadow engineering method were used to quantitatively assess the economic loss resulting from land deterioration. Results showed that the economic loss in 1999 was 326.81 billion RMB Yuan, which accounted for 4.1% of GDP in the same year of China. If taking five items namely farmland conversion, soil erosion, salinization, decline in reservoir functions, and siltation in waterways and, comparing with that in 1992, the percentage of economic loss to GDP has increased by 1.5 in the only 7 years.

    Full Text Available With an annual loss averaging 580 M€ between 1990 and 2014, floods are the main natural catastrophe (Nat Cat risk for the French Nat Cat compensation scheme. As part of its role in this scheme, the Caisse Centrale de Réassurance (CCR offers state guaranteed reinsurance programs and has been modelling the risk of flooding since 2003. This model is based on the traditional valuation approach of direct tangible costs which pairs a physical model with exposure through damage curves. CCR wishes now to widen the studied damage scope to insured and noninsured economic costs and has been collaborating with the SAF research laboratory from the Institute of Financial and Insurance Sciences (ISFA since 2014. CCR’s model has been used to estimate the insured direct damage to residential and non-residential properties and it is now being developed to include damage to vehicles, agriculture and network infrastructures. Research is also being carried out to take into account business interruptions and indirect losses using an Input-Output model. This article describes the undergoing work on model development to estimate the damage to agriculture.

    2017-01-01

    Potatoes are one of the commodities with the highest loss shares along the entire supply chain. In the present study, we analyzed six potential loss reduction scenarios concerning their environmental-socio-economic sustainability compared with the current situation by using the "SustainOS" methodology. For this purpose, life cycle assessments, full-cost calculations and an online consumer survey were conducted. Environmental improvements through loss reduction were rather small and did not cross limits of significance, but the socio-economic performance of the entire supply chain can be improved considerably. Pearson correlation coefficients and linear regression analyses were used to predict the influence of specific subjective items like the intention to avoid food loss, knowledge related to food loss and consumers' price sensitivity on the assigned preference. Results show that perceived risks, perceived inconvenience and the general acceptance of loss-reducing instruments influence consumers' preferences. Altogether, only three out of six tested scenarios seem realistic: selling unwashed potatoes in a lightproof box, selling unpacked potatoes, and improved quality sorting at farms. For two of the other scenarios, consumers significantly indicated their refusal even if losses decreased considerably, whereas the sixth scenario was unfavorable from a socio-economic perspective.

  6. The Role of Geoscience Information in Reducing Catastrophic Loss Using a Web-Based Economics Experiment

    What role can geoscience information play in the assessment of risk and the value of insurance, especially for natural hazard type risks? In an earlier, related paper Ganderton and others (2000) provided subjects with relatively simple geoscience information concerning natural hazard-type risks. Their research looked at how subjects purchase insurance when faced with relatively low probability but high loss risks of the kind that characterize natural hazards and now, increasingly, manmade disasters. They found evidence to support the expected utility theory (definitions of economics terms can be found in a glossary at the end of report), yet there remained the implication that subjects with excessive aversion to risk were willing to pay considerably more for insurance than the actuarially fair price plus any reasonable risk premium. Here, we report the results of additional experiments that provide further support for the basic postulates of expected utility theory. However, these new experiments add considerably to the decision environment facing subjects by offering an option to purchase geoscientific information that would assist them when calculating expected losses from hazards more accurately. Using an Internet-based mechanism to present information and gather data in an experimental setting, this research provided subjects with considerable textual and graphical information, and time to process it. Over a period of three months, almost 400 subjects participated in on-line experiments that generated approximately 22,000 usable data points for the empirical analysis discussed in this report. In the design of the experiment, we modeled the decisions to purchase (1) a detailed map giving subjects more information regarding the distribution of losses from a hazard and (2) insurance to indemnify them from any losses should they occur. On the basis of this design, we find strong evidence in support of the expected utility theory. Many of the findings reinforce

    The aim of this study was to investigate the epidemiology and transmission of Taenia hydatigena in sheep and dogs from Sardinia and the economic estimation of losses due to this metacestodosis in lambs. A total of 7781 Sarda breed lambs were examined at abattoirs for the detection of Cysticercus tenuicollis or necrotic-haemorrhagic tracks of their migration. Morphological and molecular identification of parasites was carried out. Individual faecal samples from 300 dogs were examined for copromicroscopic investigations and coproELISA assay. An overall prevalence of 14.6% for T. hydatigena cysticercosis was found in the examined lambs. In total, 10,807 parasitary tracks were found, with an abundance of 1.39 and an average intensity of 9.52. The molecular analysis of the isolates showed an overall pairwise nucleotide divergence for the CO1 and ND1 was of 0-3.1 and 0-3.3%, respectively. Low intra- and interspecific variation was recorded for C. tenuicollis isolates used in this study which suggested the absence of differentiation. Microscopic examination of dog faeces showed a total prevalence of 31.3% for endoparasites in the examined samples (94/300). Taeniid eggs were found in 8.3% of the dogs. The results of the monoclonal antibody ATH4 ELISA test showed a prevalence of 11% (33/300) for T. hydatigena coproantigens. The total economic costs related to cysticercosis amounted to almost € 330,000. The prevalence of C. tenuicollis in 14.6% of 30-40-day-old lambs highlights the high parasitic pressure by T. hydatigena in the territory of Sardinia, Italy.

  8. Assessment of the Economic Losses Resulting from Land Subsidence in Bandung Basin, Indonesia

    2012-04-01

    The Bandung Basin is a large intra-montane basin surrounded by volcanic highlands, in western Java, Indonesia, inhabited by more than seven million people. The basin, an area of about 2300 km2, is a highland plateau at approximately 650-700 m above sea level and is surrounded by up to 2400 m high Late Tertiary and Quaternary volcanic terrain. Based on the results of 9 GPS surveys conducted since 2000 up to 2011 it was shown that several locations in the Bandung Basin have experienced land subsidence, with an average rate of about -8 cm/year and can go up to about -23 cm/year in certain locations. A similar rate of subsidence was also detected by the InSAR (Interferometric Synthetic Aperture Radar) technique. In general, the impacts of land subsidence in Bandung basin could be seen in several forms, such as cracking of houses, permanent constructions and roads, changes in river canal and drain flow systems, wider expansion of flooding areas, and malfunction of drainage system. The tangible and intangible impacts of land subsidence cannot be underestimated. The primary environmental and economic effects of land subsidence phenomena can vary from negligible to severe depending on the present land-use nature of the affected area and the subsidence magnitude and coverage. The indirect effects of subsidence through aggravation of other hazards already present in the area are frequently more severe than the direct effects. In the case of Bandung basin, the increase in flooding coverage caused by continuing subsidence introduce more problems compared to other indirect effects of land subsidence. Land subsidence also Increases the maintenance costs for the affected buildings and infrastructure, and lowering the quality of living environment (e.g. health and sanitation condition) and ecosystem in the affected areas. Although not easy, quantitative assessment of economic losses resulting from land subsidence in Bandung basin has been carried out. Methodology and estimated

    Food wastage costs society far more than the direct economic loss of US$ 750 billion per year. When food is discarded, all embodied natural resources are wasted, too. The aim of this study is to estimate global environmental costs of soil erosion and the loss of biodiversity and ecosystem services caused by food wastage. Firstly, environmental indicators and their quantities such as soil erosion rates, N, P and pesticide inputs and land use changes to agricultural production were assessed thr...

    The expected economic losses to buildings due to the tsunami impact is of particular importance for the tsunami risk management. However, only few efforts can be found in this direction. In this study we approached this issue selecting the city of Rhodes Isl., Greece, as a test-site. The methodological steps followed include (a) selection of worst case scenario in the study area based on the tsunami history of the area which includes several powerful events, e.g. 142 AD, 1303, 1481, 1609, 1741, (b) numerical simulation of the tsunami and determination of the inundation zone, (c) application of the DAMASCHE empirical tool, produced by the SCHEMA EU-FP6 project, for the calculation of the damage level expected at each one of the buildings as a function of the water depth in the inundation area, (d) calculation of the buildings that would need reparation after partial damage and of those that would need reconstruction after total destruction, (e) calculation of the cost implied for both reparation and reconstruction. The several data sets which are needed for the execution of these steps, are susceptible to uncertainties and, therefore, the final results are quite sensitive to changes of the data sets. Alternative costs were calculated by taking into account the several uncertainties involved. This research is a contribution to the EU-FP7 tsunami research project ASTARTE (Assessment, Strategy And Risk Reduction for Tsunamis in Europe), grant agreement no: 603839, 2013-10-30.

  12. Neglecting rice milling yield and quality underestimates economic losses from high-temperature stress.

    Directory of Open Access Journals (Sweden)

    Nathaniel B Lyman

    Full Text Available Future increases in global surface temperature threaten those worldwide who depend on rice production for their livelihoods and food security. Past analyses of high-temperature stress on rice production have focused on paddy yield and have failed to account for the detrimental impact of high temperatures on milling quality outcomes, which ultimately determine edible (marketable rice yield and market value. Using genotype specific rice yield and milling quality data on six common rice varieties from Arkansas, USA, combined with on-site, half-hourly and daily temperature observations, we show a nonlinear effect of high-temperature stress exposure on yield and milling quality. A 1 °C increase in average growing season temperature reduces paddy yield by 6.2%, total milled rice yield by 7.1% to 8.0%, head rice yield by 9.0% to 13.8%, and total milling revenue by 8.1% to 11.0%, across genotypes. Our results indicate that failure to account for changes in milling quality leads to understatement of the impacts of high temperatures on rice production outcomes. These dramatic losses result from reduced paddy yield and increased percentages of chalky and broken kernels, which together decrease the quantity and market value of milled rice. Recently published estimates show paddy yield reductions of up to 10% across the major rice-producing regions of South and Southeast Asia due to rising temperatures. The results of our study suggest that the often-cited 10% figure underestimates the economic implications of climate change for rice producers, thus potentially threatening future food security for global rice producers and consumers.

    In spite of the recent improved results of hepatectomy for huge hepatocellular carcinomas (HCC), the prognosis of patients with huge HCCs is still poor compared to that of patients with small HCCs. This study was performed to compare the results of hepatectomy between patients with huge HCCs and those with small HCCs, to identify the prognostic factors in patients with huge HCCs, and to determine the preoperative selection criteria. We retrospectively analyzed 51 patients who underwent hepatectomy, between July 1994 and February 2009 at Dankook University Hospital. Patients with HCC≥10 cm were classified in large (L) group and others were classified in small (S) group. The clinicopathological features, operative procedures, and postoperative outcome were compared between both groups and various prognostic factors were investigated in group L. Eleven patients were classified in group L. Tumor size, vascular invasion, and tumor stage were higher in group L. Postoperative morbidity was higher in group L, but mortality was not different between the groups. Disease-free survivals were significantly lower in group L than in group S (36.4%, and 24.2% vs. 72.0%, and 44.0% for 1- and 3-year), but overall survival rates were similar in both groups (45.5%, and 15.2% in group L vs. 60.3%, and 41.3% in group S for 3- and 5-year). Presence of satellite nodules was the only prognostic factor in multivariate analysis after surgery for huge HCC. Regardless of tumor size, huge HCCs deserve consideration for surgery in patients with preserved liver function. Furthermore, the effect of surgery could be maximized with appropriate selection criteria, such as huge HCC without satellite nodules.

    Air pollution is severe in China, and pollutants such as PM2.5 and surface O3 may cause major damage to human health and crops, respectively. Few studies have considered the health effects of PM2.5 or the loss of crop yields due to surface O3 using model-simulated air pollution data in China. We used gridded outputs from the WRF-Chem model, high resolution population data, and crop yield data to evaluate the effects on human health and crop yield in mainland China. Our results showed that outdoor PM2.5 pollution was responsible for 1.70-1.99 million cases of all-cause mortality in 2006. The economic costs of these health effects were estimated to be 151.1-176.9 billion USD, of which 90% were attributed to mortality. The estimated crop yield losses for wheat, rice, maize, and soybean were approximately 9, 4.6, 0.44, and 0.34 million tons, respectively, resulting in economic losses of 3.4 billion USD. The total economic losses due to ambient air pollution were estimated to be 154.5-180.3 billion USD, accounting for approximately 5.7%-6.6% of the total GDP of China in 2006. Our results show that both population health and staple crop yields in China have been significantly affected by exposure to air pollution. Measures should be taken to reduce emissions, improve air quality, and mitigate the economic loss. Copyright © 2016. Published by Elsevier B.V.

    Primary liver liposarcoma is a rare disease. Because of its rarity, the knowledge of the clinical course, management, and prognosis of primary liver liposarcoma are all limited for clinicians. A 61-year-old female patient who suffered from a huge primary liposarcoma in the central portion of the liver had the clinical presentations of fever, nausea, vomiting, jaundice, and body weight loss.The huge tumor was resected successfully. However,the tumor recurred repeatedly and she had repeated hepatectomies to remove the tumor. Thetumor became aggravating after repeated surgeries. Eventually, the patient had cervical spinal metastasis of liposarcoma and she survived for 26 months after liver liposarcoma was diagnosed. Although the tumor may become aggravating after repeated surgeries, repeated hepatectomies are still the best policy to achieve a long-term survival for the patients.

    The objective of the study was to estimate the losses associated with subclinical mastitis (SCM) in crossbred dairy cows in the Central Highlands of Ethiopia. A split udder investigation was performed with 30 cows to determine production losses associated with SCM. Each quarter of the study cows was examined using the California Mastitis Test (CMT) and quarter milk production was measured over a period of 8 days. Production losses were determined for different CMT scores by comparing production of quarters with CMT score 0 to quarters with CMT scores trace, 1, 2 and 3, respectively. Using data from a recently published study, economic losses were determined for different farm sizes and production subsystems by multiplying the prevalence of the respective CMT scores with the production losses associated with these CMT scores. Mean quarter milk production was 0.82 +/- 0.40 kg per milking in the split udder trial. Milk production was reduced by 1.2%, 6.3%, and 33% in quarters with CMT scores 1+, 2+, and 3+, respectively. Using data from the published study, a quarter with SCM lost an average of 17.2% of its milk production. Production losses associated with SCM were estimated at 5.6% for the Addis Ababa Milk Shed. Stratified losses were highest (9.3%) in urban dairy farms (UDF) and small-scale farms (6.3%). The estimates of the financial losses ranged from US dollars 29.1 in dairy herds in secondary towns (DHIST) to US dollars 66.6 in UDF. A total loss of US dollars 38 was estimated for each cow per lactation. Reducing mastitis in UDF (highest prevalence) to the level of DHIST (lowest prevalence) could reduce the loss by US dollars 35. As this does not include costs associated with treatment or culling of diseased cows, this figure probably underestimates the possible benefits of control measures.

    The objective of the study was to estimate the prevalence and losses associated with subclinical mastitis (SCM) caused by Staphylococcus aureus in Ethiopian crossbred dairy cows. A split-udder trial was carried out to determine milk yield losses in udder quarter with S. aureus-caused SCM. Each quarter of the study cows was examined using the California Mastitis Test (CMT) and quarter milk production was measured over a period of 8 days. Milk yield losses for CMT positive quarters were estimated by comparing production of quarters with CMT score 0. Mean milk yield for uninfected healthy quarters was 1.66 kg per milking (95% CI, 1.66-1.55 kg per milking), and the rate of milk reduction for quarters with CMT scores of 1+, 2+, and 3+ was 25%, 33%, and 48%, respectively. Economic losses at different farm-size levels were calculated by multiplying the prevalence of CMT scores with milk yield losses associated with respective CMT scores. In Debre Ziet dairy herds, a quarter with SCM due to S. aureus lost an average of 34.5% of its potential milk production while the total milk yield loss per cow was estimated at 6.8%. Losses were highest in large-scale (13%) farms and lowest (3.7%) in small-scale. Based on the prevalence, the overall financial loss for each cow per lactation was 984.64 Eth Birr (US$78.65) and losses in large farms (1,882.40 Eth Birr or US$150.35) were over 3.5 times the loss in small-size farms. These figures possibly underestimate the potential benefits of mastitis control program as they do not include other direct and indirect costs.

    The main objective of this work is to compare the potential direct economic losses between two different hazards in Guadeloupe (French Antilles), earthquakes and storm surges, for different return periods. In order to validate some hypotheses which are done concerning building typologies and their insured values a comparison between real economic loss data and estimated ones is done using a real event. In 2004 there was an earthquake in Guadeloupe, Mw 6.3, in a little archipelago in the south of Guadeloupe called Les Saintes. The heaviest intensities were VIII in the municipalities of Les Saintes and decreases from VII to IV in the other municipalities of Guadeloupe. The CCR, French Reinsurance Organism, has provided data about the total insured economic losses estimated per municipality (in a situation in 2011) and the insurance penetration ratio, it means, the ratio of insured exposed elements per municipality. Some other information about observed damaged structures is quite irregular all over the archipelago, being the only reliable one the observed macroseismic intensity per municipality (field survey done by BCSF). These data at Guadeloupe's scale has been compared with results coming from a retro damage scenario for this earthquake done with the vulnerability data from current buildings and their mean economic value of each building type and taking into account the local amplification effects on the earthquake propagation. In general the results are quite similar but with some significant differences. The results coming from scenario are quite correlated with the spatial attenuation from the earthquake intensity; the heaviest economic losses are concentrated within the municipalities exposed to a considerable and damageable intensity (VII to VIII). On the other side, CCR data show that heavy economic damages are not only located in the most impacted cities but also in the most important municipalities of the archipelago in terms of economic activity

    Slow earthquakes are characterized by a wide spectrum of fault slip behaviors and seismic radiation patterns that differ from those of traditional earthquakes. However, slow earthquakes and huge megathrust earthquakes can have common slip mechanisms and are located in neighboring regions of the seismogenic zone. The frequent occurrence of slow earthquakes may help to reveal the physics underlying megathrust events as useful analogs. Slow earthquakes may function as stress meters because of their high sensitivity to stress changes in the seismogenic zone. Episodic stress transfer to megathrust source faults leads to an increased probability of triggering huge earthquakes if the adjacent locked region is critically loaded. Careful and precise monitoring of slow earthquakes may provide new information on the likelihood of impending huge earthquakes.

However, slow earthquakes and huge megathrust earthquakes can have common slip mechanisms and are located in neighboring regions of the seismogenic zone. The frequent occurrence of slow earthquakes may help to reveal the physics underlying megathrust events as useful analogs. Slow earthquakes may function as stress meters because of their high sensitivity to stress changes in the seismogenic zone. Episodic stress transfer to megathrust source faults leads to an increased probability of triggering huge earthquakes if the adjacent locked region is critically loaded. Careful and precise monitoring of slow earthquakes may provide new information on the likelihood of impending huge earthquakes.

    Central neurocytomas (CNs), initially asymptomatic, sometimes become huge before detection. We described and analyzed the clinical, radiological, operational and outcome data of 13 cases of huge intraventricular CNs, and discussed the treatment strategies in this study. All huge CNs (n=13) in our study were located in bilateral lateral ventricle with diameter ≥5.0 cm and had a broad-based attachment to at least one side of the ventricle wall. All patients received craniotomy to remove the tumor through transcallosal or transcortical approach and CNs were of typical histologic and immunohistochemical features. Adjuvant therapies including conventional radiation therapy (RT) or gamma knife radiosurgery (GKRS) were also performed postoperatively. Transcallosal and transcortical approaches were used in 8 and 5 patients, respectively. Two patients died within one month after operation and 3 patients with gross total resection (GTR) were additionally given a decompressive craniectomy (DC) and/or ventriculoperitoneal shunt (VPS) as the salvage therapy. Six patients received GTR(+RT) and 7 patients received subtotal resection (STR)(+GKRS). Eight patients suffered serious complications such as hydrocephalus, paralysis and seizure after operation, and patients who underwent GTR showed worse functional outcome [less Karnofsky performance scale (KPS) scores] than those having STR(+GKRS) during the follow-up period. The clinical outcome of huge CNs seemed not to be favorable as that described in previous reports. Surgical resection for huge CNs should be meticulously considered to guarantee the maximum safety. Better results were achieved in STR(+GKRS) compared with GTR(+RT) for huge CNs, suggesting that STR(+GKRS) may be a better treatment choice. The recurrent or residual tumor can be treated with GKRS effectively.

    Objective To estimate the economic burden of vision loss and eye disorders in the United States population younger than 40 years in 2012. Design Econometric and statistical analysis of survey, commercial claims, and census data. Participants The United States population younger than 40 years in 2012. Methods We categorized costs based on consensus guidelines. We estimated medical costs attributable to diagnosed eye-related disorders, undiagnosed vision loss, and medical vision aids using Medical Expenditure Panel Survey and MarketScan data. The prevalence of vision impairment and blindness were estimated using National Health and Nutrition Examination Survey data. We estimated costs from lost productivity using Survey of Income and Program Participation. We estimated costs of informal care, low vision aids, special education, school screening, government spending, and transfer payments based on published estimates and federal budgets. We estimated quality-adjusted life years (QALYs) lost based on published utility values. Main Outcome Measures Costs and QALYs lost in 2012. Results The economic burden of vision loss and eye disorders among the United States population younger than 40 years was $27.5 billion in 2012 (95% confidence interval, $21.5–$37.2 billion), including $5.9 billion for children and $21.6 billion for adults 18 to 39 years of age. Direct costs were $14.5 billion, including $7.3 billion in medical costs for diagnosed disorders, $4.9 billion in refraction correction, $0.5 billion in medical costs for undiagnosed vision loss, and $1.8 billion in other direct costs. Indirect costs were $13 billion, primarily because of $12.2 billion in productivity losses. In addition, vision loss cost society 215 000 QALYs. Conclusions We found a substantial burden resulting from vision loss and eye disorders in the United States population younger than 40 years, a population excluded from previous studies. Monetizing quality-of-life losses at $50 000 per QALY would

    Success in many decision-making scenarios depends on the ability to maximize gains and minimize losses. Even if an agent knows which cues lead to gains and which lead to losses, that agent could still make choices yielding suboptimal rewards. Here, by analyzing event-related potentials (ERPs) recorded in humans during a probabilistic gambling task, we show that individuals' behavioral tendencies to maximize gains and to minimize losses are associated with their ERP responses to the receipt of those gains and losses, respectively. We focused our analyses on ERP signals that predict behavioral adjustment: the frontocentral feedback-related negativity (FRN) and two P300 (P3) subcomponents, the frontocentral P3a and the parietal P3b. We found that, across participants, gain maximization was predicted by differences in amplitude of the P3b for suboptimal versus optimal gains (i.e., P3b amplitude difference between the least good and the best gains). Conversely, loss minimization was predicted by differences in the P3b amplitude to suboptimal versus optimal losses (i.e., difference between the worst and the least bad losses). Finally, we observed that the P3a and P3b, but not the FRN, predicted behavioral adjustment on subsequent trials, suggesting a specific adaptive mechanism by which prior experience may alter ensuing behavior. These findings indicate that individual differences in gain maximization and loss minimization are linked to individual differences in rapid neural responses to monetary outcomes.

    Aggravated air pollution in Beijing, China has caused serious health concern. This paper comprehensively evaluates the health losses from illness and premature death caused by air pollution in monetary terms. We use the concentration of PM10 as an indicator of the pollution since it constitutes the primary pollutant in Beijing. By our estimation, air pollution in Beijing caused a health loss equivalent to Ұ583.02 million or 0.03 % of its GDP. Most of the losses took the form of depreciation in human capital that resulted from premature death. The losses from premature deaths were most salient for people of either old or young ages, with the former group suffering from the highest mortality rates and the latter group the highest per capital losses of human capitals from premature death. Policies that target on PM10 emission reduction, urban vegetation expansion, and protection of vulnerable groups are all proposed as possible solutions to air pollution risks in Beijing.

    The economic downturn of 2007 created significant fiscal losses for public and private agencies conducting behavioral prevention. Such macro-economic changes may influence program implementation and sustainability. We examined how public and private agencies conducting RESPECT, a brief HIV/STI (sexually transmitted infection) counseling and testing intervention, adapted to fiscal loss and how these adaptations impacted program fidelity. We collected qualitative and quantitative data in a national sample of 15 agencies experiencing fiscal loss. Using qualitative analyses, we examined how program fidelity varied with different types of adaptations. Agencies reported three levels of adaptation: agency-level, program-level, and direct fiscal remedies. Private agencies tended to use direct fiscal remedies, which were associated with higher fidelity. Some agency-level adaptations contributed to reductions in procedural fit, leading to negative staff morale and decreased confidence in program effectiveness, which in turn, contributed to poor fidelity. Findings describe a "work stress pathway" that links program fiscal losses to poor staff morale and low program fidelity.

    Full Text Available The depth and duration of the credit crisis has highlighted a number of problems in modern finance. Banks have been accused of excessive risk taking, rating agencies of severe conflicts of interest, central banks of neglecting the inflation of asset price bubbles and national supervisors of lax regulatory controls. Credit and market losses have been considerable. Operational losses have also surged as surviving corporates merge or acquire less fortunate ones without the requisite controls. Furthermore, as more jobs get made redundant it is believed that people are getting forced to play their hand to get involved in internal fraud as their sources of income has dried up drastically and stealing from the institution seems to be their last resort.. The main objective of this paper is to establish if there has been a changed in the nature of operational risk with regards to the number of operational losses as well as their impact pre and during the crisis. The way in which operational losses have been affected will be presented and a comparison will be made between operational loss characteristics pre and during the crisis. Some of the main findings of this paper were that operational losses shown little change in frequency, but shown a significant increase in severity, meaning that their financial impact has been more severe during the crisis.  Therefore it is quite safe to say that the financial crisis most defiantly had an impact on operational risk as the impact of operational losses became much more severe

    Full Text Available A huge left renal capsular leiomyoma mimicking retroperitoneal sarcoma presented in a patient as an abdominal mass. Computed tomography displayed a large heterogeneous retro-peritoneal mass in the left side of the abdomen with inferior and medial displacement as well as loss of fat plane with the left kidney. Surgical exploration revealed a capsulated mass that was tightly adherent to the left kidney; therefore, total tumor resection with radical left nephrectomy was performed. Histopathology ultimately confirmed the benign nature of the mass. This is the largest leiomyoma reported in literature to the best of our knowledge.

    Recent surveys suggest tens of thousands of elephants are being poached annually across Africa, putting the two species at risk across much of their range. Although the financial motivations for ivory poaching are clear, the economic benefits of elephant conservation are poorly understood. We use Bayesian statistical modelling of tourist visits to protected areas, to quantify the lost economic benefits that poached elephants would have delivered to African countries via tourism. Our results show these figures are substantial (∼USD $25 million annually), and that the lost benefits exceed the anti-poaching costs necessary to stop elephant declines across the continent's savannah areas, although not currently in the forests of central Africa. Furthermore, elephant conservation in savannah protected areas has net positive economic returns comparable to investments in sectors such as education and infrastructure. Even from a tourism perspective alone, increased elephant conservation is therefore a wise investment by governments in these regions. PMID:27802262

    2011-01-01

    Full Text Available Although its socio-economic disaster pattern was obvious, the March 4, 1977 Vrancea, Romania earthquake was studied mainly in seismological and earthquake engineering terms. In 1977, the loss data released in Romania, referred to 32,900 collapsed or heavily damaged dwellings, 35,000 homeless families, thousands of damaged buildings, many other damages and destructions in industry and economy, 1,578 people killed, 11,321 people injured (with 90% of the killed and 67% of the injured being in the city of Bucharest. The Romanian government reported the economic losses from this event in December 1977, as being US$ 2 billion. For a long time, the evaluation of human casualties vs. collapse pattern of buildings in 1977 was not addressed and we still miss integral data. The recovery and reevaluation of economic and social impacts of the 1977 disaster was a concern of the authors, with the intent to better understand its consequences and prepare a new strategy of seismic risk reduction in view of future earthquakes in Romania, and in order to fill that gap the authors recovered many unpublished and obscure data.

    Full Text Available Rapeseed cultivation in Iran is growing rapidly while this product has been facing specific problems. Every year a significant portion of edible oil is imported to the country from other countries. Despite this deficit, a great amount of canola is being lost every year. Therefore, in compliance with technical points, adding a suitable platform to the exisiting machineries may reduce the losses. A field study was conducted in Moghan Agricultural Research Centre to study the technical and economical characteristics of harvesting machineries and evaluate Canola harvesting losses in different maturity stages, using three different combine harvester heads. The experiments were conducted in a completely randomized\tsplit split plot design with four replications. The main plot included seed maturity stage at three levels: A 60%, B 70% and C 80%, and the subplot was the harvester’s ground speed at three levels: A 1.5, B 2.5 and C 3.5 km h-1. The sub-subplot was combine head type with three forms: A Mechanical, B Hydraulically Joybar and C Hydraulically Biso's Head. The results of ANOVA showed that maximum cutter bar losses occurred with Mechanical Head (5.36% while the loss of Hydraulically Joybar's and Biso's head were 4.28 and 4.13 %, respectively. The results also showed that the maximum cutter bar losses occurred when 80% of seeds were matured and adequate time for canola harvesting was 70% of seeds maturity. The results of analysing the effects of harvesting ground speeds showed that the maximum cutter bar losses occurred with the speed of 3.5 km h-1. Finally, the results showed that the minimum cutter bar loss was obtained with Hydraulically Joybar's head considering the benefit per cost ratio. The cost for Mechanical head and Hydraulically Biso's head were 13500 and 262500 Rial ha-1, respectively.

    Perineural cysts have become a common incidental finding during lumbosacral magnetic resonance (MR) imaging. Only some of the symptomatic cysts warrant treatment. The authors describe the successful operative treatment of a patient with, to the best of their knowledge, the largest perineural cyst reported to date. A 29-year-old woman had been suffering from long-standing constipation and low-back pain. During an obstetric investigation for infertility, the clinician discovered a huge presacral cystic mass. Computed tomography myelography showed the lesion to be a huge Tarlov cyst arising from the left S-3 nerve root and compressing the ipsilateral S-2 nerve. The cyst was successfully treated by ligation of the cyst neck together with sectioning of the S-3 nerve root. Postoperative improvement in her symptoms and MR imaging findings were noted. Identification of the nerve root involved by the cyst wall, operative indication, operative procedure, and treatment of multiple cysts are important preoperative considerations.

    We compare 6 forecasts productions models on two windfarms located in France. The evaluation is made in terms of root mean square errors. The power production forecasts are the products of both physical and statistical models and cover a period of 6 months. We show that the economic performances of those models can be improved using econometric approaches, where we to minimize the cost induced by the forecast error instead of minimizing the forecast error itself. This technique relies on state of the art non-parametric estimators of conditional probability distribution functions (cpdf) of energy production at a wind farm, given the wind speed forecasts of a deterministic meteorological model. In this case, no assumption is made about the shape of the underlying laws. The economical benefits of ensemble versus deterministic wind speed forecasts are also assessed.

    Full Text Available Modern society is characterised not only by a fascination with scientific technology as a means of solving all problems, especially those that stand in the way of material progress (technicism, but also by an obsessive interest in everything that has to do with money (economism or mammonism. The article discusses the relationship between technicism and economism, on the basis of their relationship to utilitarian thinking: the quest for the greatest happiness for the greatest number of people. Recent major studies of neo-liberalism (seen as an intensification of utilitarianism by Laval and Dardot are used as reference to the development of utilitarianism. It is suggested that the western view of the world, as expressed in economism and technicism, with a utilitarian ethics, features three absolutisations: those of theoretical thinking, technology and economics. In a second part, the article draws on the framework of reformational philosophy to suggest an approach that, in principle, is not marred by such absolutisations.

    Full Text Available An investigation carried out in the Western Carpathian Mountains (Ujsoły, Węgierska Górka, Ustroń and Wisła Forest Districts demonstrated a strong relationship between dieback in Norway spruce stands and the intensity of occurrence of Armillaria ostoyae. For the most endangered site types – mountain deciduous forest (LG and mountain mixed forest (LMG, analyses of losses of annual volume increment and of stand productivity were performed, and their financial dimensions determined. The greatest losses – of about 8 m3/ha/year for tree stands of the age of 100 years, and 400 m3/ha for the rotation period – were found for LG (Mountain broadleaved forest site type.

    2016-05-01

    Despite the large implications of the use of tropical land for exports ("land absorption") on ecosystem services (ES) and global biodiversity conservation, the magnitude of these externalities is not known. We quantify the net value of ES lost in tropical countries as a result of cropland, forestland and pastureland absorption for exports after deducting ES gains through imports ("land displacement"). We find that net ES gains occur only in 7 out of the 41 countries and regions considered. We estimate global annual net losses of over 1.7 x 10(12) international dollars (I$) (I$1.1 x 10(12) if carbon-related services are not considered). After deducting the benefits from agricultural, forest and livestock rents in land replacing tropical forests, the net annual losses are I$1.3 and I$0.7 x 10(12), respectively. The results highlight the large magnitude of tropical ES losses through international trade that are not compensated by the rents of land uses in absorbed land.

    Crovelli, Robert A.; Coe, Jeffrey A.

    2008-01-01

    The Probabilistic Landslide Assessment Cost Estimation System (PLACES) presented in this report estimates the number and economic loss (cost) of landslides during a specified future time in individual areas, and then calculates the sum of those estimates. The analytic probabilistic methodology is based upon conditional probability theory and laws of expectation and variance. The probabilistic methodology is expressed in the form of a Microsoft Excel computer spreadsheet program. Using historical records, the PLACES spreadsheet is used to estimate the number of future damaging landslides and total damage, as economic loss, from future landslides caused by rainstorms in 10 counties of the San Francisco Bay region in California. Estimates are made for any future 5-year period of time. The estimated total number of future damaging landslides for the entire 10-county region during any future 5-year period of time is about 330. Santa Cruz County has the highest estimated number of damaging landslides (about 90), whereas Napa, San Francisco, and Solano Counties have the lowest estimated number of damaging landslides (5?6 each). Estimated direct costs from future damaging landslides for the entire 10-county region for any future 5-year period are about US $76 million (year 2000 dollars). San Mateo County has the highest estimated costs ($16.62 million), and Solano County has the lowest estimated costs (about $0.90 million). Estimated direct costs are also subdivided into public and private costs.

    Full Text Available Yellow nutsedge (Cyperus esculentus is adapted to flooding and reduces yield in irrigated rice. Information on the competitive ability of this weed with the crop and the size of the economic damage caused is lacking. Mathematical models quantify the damage to crops and support control decision-making. This study aimed to determine yield losses and economic thresholds (ET of this weed in the culture according to weed population and time of onset of irrigation of the crop. The field study was conducted in the agricultural year of 2010/2011 in Pelotas/RS to evaluate the competitive ability of BRS Querência in competition with different population levels of yellow nutsedge and two periods of onset of flood irrigation (14 and 21 days after emergence. The hyperbolic model satisfactorily estimated yield losses caused by yellow nutsedge. Population of yellow nutsedge was the variable most fitted to the model. The delay of seven days for the beginning of rice irrigation causes decrease in competitive ability of BRS Querência, and based on the ET calculated to the price paid for rice, it is necessary between two and thirteen plants m-2 weed to justify the control in the first and second period of irrigation, respectively. Increases in yield, price paid for rice and control efficiency of the herbicide, besides reduction of costs of controlling promote reduction of ET of yellow nutsedge in rice crops, justifying the adoption of control measures even at smaller weed population.

    Full Text Available Taiwan usually suffers severe inundation disasters during typhoons and strong rainstorms, and therefore flood mitigation is considered an important issue. To assess the effect of the Yuansantze flood diversion tunnel (YFDT on flood mitigation at the upstream reaches of the Keelung River, a three-dimensional, unstructured grid, Finite-Volume, primitive equation Community Ocean Model (FVCOM was used. The model was validated with observed data for water levels and inundation extent during different typhoon events. The simulated results show a good agreement with field measurements of water level with three historical typhoon events but underestimated the measured inundation extent with Typhoon Nari. The validated model was then applied to assess the flood mitigation and economic loss with the YFDT. The results demonstrated that the river level decreases approximately 3 m with the YFDT and that the inundation extent decreases by more than 50% in the Ruifang District with YFDT. The YDFT aims to not only mitigate hazards but also reduce economic losses. The average annual expected benefit after construction of the YFDT is approximately 184 million NTD in the Ruifang District.

    A large effort has been made over the past 10 years to promote the operational use of probabilistic or ensemble streamflow forecasts. Numerous studies have shown that ensemble forecasts are of higher quality than deterministic ones. Many studies also conclude that decisions based on ensemble rather than deterministic forecasts lead to better decisions in the context of flood mitigation. Hence, it is believed that ensemble forecasts possess a greater economic and social value for both decision makers and the general population. However, the vast majority of, if not all, existing hydro-economic studies rely on a cost-loss ratio framework that assumes a risk-neutral decision maker. To overcome this important flaw, this study borrows from economics and evaluates the economic value of early warning flood systems using the well-known Constant Absolute Risk Aversion (CARA) utility function, which explicitly accounts for the level of risk aversion of the decision maker. This new framework allows for the full exploitation of the information related to a forecasts' uncertainty, making it especially suited for the economic assessment of ensemble or probabilistic forecasts. Rather than comparing deterministic and ensemble forecasts, this study focuses on comparing different types of ensemble forecasts. There are multiple ways of assessing and representing forecast uncertainty. Consequently, there exist many different means of building an ensemble forecasting system for future streamflow. One such possibility is to dress deterministic forecasts using the statistics of past error forecasts. Such dressing methods are popular among operational agencies because of their simplicity and intuitiveness. Another approach is the use of ensemble meteorological forecasts for precipitation and temperature, which are then provided as inputs to one or many hydrological model(s). In this study, three concurrent ensemble streamflow forecasting systems are compared: simple statistically dressed

    The economic impacts of potential terrorist attacks on the New Jersey electric power system are examined using a regional econometric model. The magnitude and duration of the effects vary by type of business and income measure. We assume damage is done during in the summer 2005 quarter, a peak period for energy use. The state economy recovers within a year, if we assume that economic activity is restored in the next time period. However, if the attacks prompt an absolute of loss of activity due to firm relocation, closing, and geographical changes in expansion plans, then the economy does not fully recover by the year 2010. Hence, the electrical power system's resiliency to damage is the key to the extent and duration of any economic consequences of a terrorist attack, at least in New Jersey. The policy implication is that the costs and benefits of making the electric power system more resilient to plausible attacks should be weighed and that the restorative capacity of the system should be strengthened.

    The welfare economic consequences of reductions in nitrogen loading to the aquatic environment in Denmark are analysed with the purpose of assessing the cost-effectiveness of different abatement measures and instruments. The analyses cover a broad range of instruments and measures. These include......: nitrogen taxes at sector level implemented as deposit refund systems, fertiliser accounts and nitrogen quotas, requirements on utilisation of livestock manure, restrictions on livestock density, set aside, forestation and wetland restoration. Based on the analyses the conclusions are that deposit refund...... taxes at sector level are the most cost effective instrument at national level, while other instruments and measures have to be used to reduce nutrient emissions further in especially sensitive areas. These areas are not identified yet, and the cost of action will depend on the localisation. However...

  17. Does China's Huge External Surplus Imply an Undervalued Renminbi?

    A pegged exchange rate regime has been pivotal to China's export-led development strategy. However, its huge trade surpluses and massive build up of international reserves have been matched by large deficits for major trading partners, creating acute policy concerns abroad, especially in the USA. This paper provides a straightforward conceptual framework for interpreting the effect of China's exchange rate policy on its own trade balance and that of trading partners in the context of discrepant economic growth rates. It shows how pegging the exchange rate when output is outstripping expenditure induces China's trade surpluses and counterpart deficits for its trading partners. An important corollary is that given its strictly regulated capital account, China's persistently large surpluses imply a significantly undervalued renminbi, which should gradually become more flexible.

  18. Optimizing the District Heating Primary Network from the Perspective of Economic-Specific Pressure Loss

    2017-07-01

    Full Text Available A district heating (DH system is one of the most important components of infrastructures in cold areas. Proper DH network design should balance the initial investment and the heat distribution cost of the DH network. Currently, this design is often based on a recommended value for specific pressure loss (R = ∆P/L in the main lines. This will result in a feasible network design, but probably not be optimal in most cases. The paper develops a novel optimization model to facilitate the design by considering the initial investment in the pipes and the heat distribution costs. The model will generate all possible network scenarios consisting of different series of diameters for each pipe in the flow direction of the network. Then, the annuity on the initial investment, the heat distribution cost, and the total annual cost will be calculated for each network scenario, taking into account the uncertainties of the material prices and the yearly operating time levels. The model is applied to a sample DH network and the results indicate that the model works quite well, clearly identifying the optimal network design and demonstrating that the heat distribution cost is more important than the initial investment in DH network design.

    Ferrisia gilli Gullan (Hemiptera: Pseudococcidae) is a new pest in California pistachios, Pistacea vera L. We conducted a 3-yr field study to determine the type and amount of damage caused by F. gilli. Using pesticides, we established gradients of F. gilli densities in a commercial pistachio orchard near Tipton, CA, from 2005 to 2007. Each year, mealybug densities on pistachio clusters were recorded from May through September and cumulative mealybug-days were determined. At harvest time, nut yield per tree (5% dried weight) was determined, and subsamples of nuts were evaluated for market quality. Linear regression analysis of cumulative mealybug-days against fruit yield and nut quality measurements showed no relationships in 2005 and 2006, when mealybug densities were moderate. However, in 2007, when mealybug densities were very high, there was a negative correlation with yield (for every 1,000 mealybug-days, there was a decrease in total dry weight per tree of 0.105 kg) and percentage of split unstained nuts (for every 1,000 mealybug-days, there was a decrease in the percentage of split unstained of 0.560%), and a positive correlation between the percentage of closed kernel and closed blank nuts (for every 1,000 mealybug-days, there is an increase in the percentage of closed kernel and closed blank of 0.176 and 0.283%, respectively). The data were used to determine economic injury levels, showing that for each mealybug per cluster in May there was a 4.73% reduction in crop value associated with quality and a 0.866 kg reduction in yield per tree (4.75%).

  20. Effect of acidic deposition on productivity of forest ecosystem and estimation of its economic losses in southern suburbs of Chongqing

    Institute of Scientific and Technical Information of China (English)

    1998-01-01

    In accordance with principle sand methods of ecology,this paper studied the effects of acidic deposition on productivity and volume increment of masson pine and Cinnamomum campora forest which are widely distributed in southern suburbs of Chongqing. Based on the field data and measurements, a multivariable stepwise regression model was established to analyze the effects of multiple environmental factors on the productivity of the forest ecosystems. This model was used to assess the volume and economic losses of these two forest ecosystems caused by acidic deposition. The results showed that, among the environmental factors, pH value of precipitation, soil depth, soil organic contents and slope are the dominant ones influencing the growth of masson pine forest. It is also shown that the acidic deposition has no clear relation to the growth of C.Campora forest, so development of such broad-leaved forest is suitable in the area.

    Full Text Available Introduction: Lipomas are among the most common tumors of the human body. However, they are uncommon in the oral cavity and are observed as slow growing, painless, and asymptomatic yellowish submucosal masses. Surgical excision is the treatment of choice and recurrence is not expected.    Case Report: The case of a 30-year-old woman with a huge lipoma on the tip of her tongue since 3 years, is presented. She had difficulty with speech and mastication because the tongue tumor was filling the oral cavity. Clinical examination revealed a yellowish lesion, measuring 8 cm in maximum diameter, protruding from the lingual surface. The tumor was surgically excised with restoration of normal tongue function and histopathological examination of the tumor confirmed that it was a lipoma.   Conclusion:  Tongue lipoma is rarely seen and can be a cause of macroglossia. Surgical excision for lipoma is indicated for symptomatic relief and exclusion of associated malignancy.

    This image of a pair of colliding galaxies called NGC 6240 shows them in a rare, short-lived phase of their evolution just before they merge into a single, larger galaxy. The prolonged, violent collision has drastically altered the appearance of both galaxies and created huge amounts of heat turning NGC 6240 into an 'infrared luminous' active galaxy. A rich variety of active galaxies, with different shapes, luminosities and radiation profiles exist. These galaxies may be related astronomers have suspected that they may represent an evolutionary sequence. By catching different galaxies in different stages of merging, a story emerges as one type of active galaxy changes into another. NGC 6240 provides an important 'missing link' in this process. This image was created from combined data from the infrared array camera of NASA's Spitzer Space Telescope at 3.6 and 8.0 microns (red) and visible light from NASA's Hubble Space Telescope (green and blue).

    Full Text Available In October 2005 a devastating earthquake caused extensive damage among populations in Pakistan administered Kashmiri Region and parts of North Western Frontier. In addition to the loss of more than 87`000 human lives and 70`000 injured, many livestock namely buffaloes, cattle and goats were lost. This eroded the livelihoods of families that solely relied on livestock and agriculture for their economic survival. The International Committee of the Red Cross together with the German Red Cross (ICRC/ GRC and the Kashmiri authorities formulated a project that sought to restore the livelihoods of the most vulnerable households to a level comparable to before the earthquake. The project adapted an agro-vet and micro-economic approach, part of which included the provision of a milking cow and calf. This report indicates that antibiotics and homoeopathic medicines provide similar levels of protection against mastitis (Spranger, 2000. Preventive measures like vaccinations, disinfectant footbaths and reducing stress during the critical time of calving goes a long way towards improving the overall health of the dairy cows (Dettloff, 2005. Although milking is in many cases still done by hand, pre-milking and post-milking hygienic procedures, such as udder washing and drying greatly decrease prevalence of mastitis.

  4. On the tragedy of the commons: When predation and livestock loss may improve the economic lot of herders.

    This paper studies the practice of semi-domestic reindeer (Rangifer t. tarandus) herding in Finnmark county in northern Norway. In this area, the Saami reindeer herders compete for space and grazing areas and keep large herds, while at the same time, the reindeer population is heavily exposed to carnivore predation by the lynx (Lynx lynx), the wolverine (Gulo gulo), and the golden eagle (Aquila chrysaetos). It is demonstrated that predation actually may improve the economic lot of livestock holders in this unmanaged local common setting. There are ecological as well as economic reasons as to why this happens. The ecological reason is that predation compensates for natural mortality; that is, increased predation reduces natural mortality, indicating that the net loss due to predation actually may be quite small. When predation reduces livestock density, the feeding conditions of the animals will improve, resulting in increased livestock weight and higher per animal slaughter value. At the same time, a smaller stock reduces the operating costs of the herders.

    In this research, the main parameters of the multivariate cumulative sum (CUSUM) control chart (the reference value k, the control limit H, the sample size n and the sampling interval h) are determined by minimising the Lorenzen-Vance cost function [Lorenzen, T.J., and Vance, L.C. (1986), 'The Economic Design of Control Charts: A Unified Approach', Technometrics, 28, 3-10], in which the external costs of employing the chart are added. In addition, the model is statistically constrained to achieve desired in-control and out-of-control average run lengths. The Taguchi loss approach is used to model the problem and a genetic algorithm, for which its main parameters are tuned using the response surface methodology (RSM), is proposed to solve it. At the end, sensitivity analyses on the main parameters of the cost function are presented and their practical conclusions are drawn. The results show that RSM significantly improves the performance of the proposed algorithm and the external costs of applying the chart, which are due to real-world constraints, do not increase the average total loss very much.

  6. HUBBLE SPIES HUGE CLUSTERS OF STARS FORMED

    2002-01-01

    BY ANCIENT ENCOUNTER This stunningly beautiful image [right] taken with the NASA Hubble Space Telescope shows the heart of the prototypical starburst galaxy M82. The ongoing violent star formation due to an ancient encounter with its large galactic neighbor, M81, gives this galaxy its disturbed appearance. The smaller picture at upper left shows the entire galaxy. The image was taken in December 1994 by the Kitt Peak National Observatory's 0.9-meter telescope. Hubble's view is represented by the white outline in the center. In the Hubble image, taken by the Wide Field and Planetary Camera 2, the huge lanes of dust that crisscross M82's disk are another telltale sign of the flurry of star formation. Below the center and to the right, a strong galactic wind is spewing knotty filaments of hydrogen and nitrogen gas. More than 100 super star clusters -- very bright, compact groupings of about 100,000 stars -- are seen in this detailed Hubble picture as white dots sprinkled throughout M82's central region. The dark region just above the center of the picture is a huge dust cloud. A collaboration of European and American scientists used these clusters to date the ancient interaction between M82 and M81. About 600 million years ago, a region called 'M82 B' (the bright area just below and to the left of the central dust cloud) exploded with new stars. Scientists have discovered that this ancient starburst was triggered by the violent encounter with M81. M82 is a bright (eighth magnitude), nearby (12 million light-years from Earth) galaxy in the constellation Ursa Major (the Great Bear). The Hubble picture was taken Sept. 15, 1997. The natural-color composite was constructed from three Wide Field and Planetary Camera 2 exposures, which were combined in chromatic order: 4,250 seconds through a blue filter (428 nm); 2,800 seconds through a green filter (520 nm); and 2,200 seconds through a red (820 nm) filter.

  7. A pharmaco-economic analysis of patients with schizophrenia switching to generic risperidone involving a possible compliance loss

    2009-02-01

    Full Text Available Abstract Background As schizophrenia patients are typically suspicious of, or are hostile to changes they may be reluctant to accept generic substitution, possibly affecting compliance. This may counteract drug costs savings due to less symptom control and increased hospitalization risk. Although compliance losses following generic substitution have not been quantified so far, one can estimate the possible health-economic consequences. The current study aims to do so by considering the case of risperidone in Germany. Methods An existing DES model was adapted to compare staying on branded risperidone with generic substitution. Differences include the probability of non-compliance and medication costs. Incremental probability of non-compliance after generic substitution was varied between 2.5% and 10%, while generic medication costs were assumed to be 40% lower. Effect of medication price was assessed as well as the effect of applying compliance losses to all treatment settings. The probability of staying on branded risperidone being cost-effective was calculated for various outcomes of a hypothetical study that would investigate non-compliance following generic substitution of risperidone. Results If the incremental probability of non-compliance after generic substitution is 2.5%, 5.0%, 7.5% and 10% respectively, incremental effects of staying on branded risperidone are 0.004, 0.007, 0.011 and 0.015 Quality Adjusted Life Years (QALYs. Incremental costs are €757, €343, -€123 and -€554 respectively. Benefits of staying on branded risperidone include improved symptom control and fewer hospitalizations. If generic substitution results in a 5.2% higher probability of non-compliance, the model predicts staying on branded risperidone to be cost-effective (NICE threshold of ₤30,000 per QALY gained. Compliance losses of more than 6.9% makes branded risperidone the dominant alternative. Results are sensitive to the locations at which compliance

    The spotted wing drosophila (SWD), Drosophila suzukii (Matsumura), is an invasive vinegar fly with a preference for infesting commercially viable berries and stone fruits. SWD infestations can reduce yields significantly, necessitating additional management activities. This analysis estimates economic losses in the California raspberry industry that have resulted from the SWD invasion. California raspberry producers experienced considerable revenue losses and management costs in the first years following SWD's invasion of North America. Conventional producers have since developed effective chemical management programs, virtually eliminating revenue losses due to SWD and reducing the cost of management to that of purchasing and applying insecticides more often. Organic raspberry producers, who do not have access to the same chemical controls, continue to confront substantial SWD-related revenue losses. These losses can be mitigated only by applying expensive insecticides registered for organic use and by performing labor-intensive field sanitation. SWD's invasion into North America has caused extensive crop losses to berry and cherry crops in California and elsewhere. Agricultural producers and researchers have responded quickly to this pest by developing management programs that significantly reduce revenue losses. Economic losses are expected to continue to fall as producers learn to manage SWD more efficiently and as new control tactics become available. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

    Full Text Available Abstract Background The prevalence of obesity is over 25 % in many developed countries. Obesity is strongly associated with an increased risk of fatal and chronic conditions such as cardiovascular disease and type 2 diabetes. Therefore it has become a major public health concern for many economies. E-learning devices are a relatively novel approach to promoting dietary change. The new generation of devices are ‘adaptive’ and use interactive electronic media to facilitate teaching and learning. E-Learning has grown out of recent developments in information and communication technology, such as the Internet, interactive computer programmes, interactive television and mobile phones.

Outcomes were expressed in terms of Quality-Adjusted Life-Years (QALYs and costs were estimated from a health services perspective. All parameter estimates were derived from the literature. A systematic review was undertaken to derive the estimate of relative treatment effect. Results The base case results from the e-Learning Economic Evaluation Model (e-LEEM suggested that the incremental cost-effectiveness ratio was approximately £102,000 per Quality-Adjusted Life-Year (QALY compared to conventional care.

    Full Text Available Background: Huge umbilical hernias (HUH are voluminous umbilical hernia (UH that are frequent in black African children. Several surgical techniques are used in their treatment for umbilical reconstruction, but techniques using skin flaps provide better aesthetic results. In this study, we presented our technique of umbilicoplasty in HUH, and its results. Patients and Methods: It is a retrospective study on children treated for HUH, from January 2012 to December 2013. The UH was called HUH when its basis diameter (BD exceeds 3 cm. Every HUH was characterised by its height, BD and morphology. Our technique was a two lateral flaps technique; the flaps are symmetrical and drawn so as to reconstitute the different parts of the umbilicus. The results were appreciated with criteria, including the peripheral ring and the central depression of the neo-umbilicus. Results : Twelve children were concerned (7 boys and 5 girls. Their mean age was 5 years and 6 months. The mean BD was 5.6 cm (extremes 3 and 8 cm, and the mean height of the HUH was 7.45 cm (extremes 3 and 9 cm. All underwent umbilicoplasty. In early post-operative period, two children presented a transitory subcutaneous hematoma. Late complications were granulation tissue with two children, and cheloid scar with one. With a mean follow-up of 10 months, we had 10 excellent results and two fair results according to our criteria. Conclusion: Our two lateral flaps umbilicoplasty is well-adapted to HUH in children. It is simple and assures a satisfactory anatomical and cosmetic result.

    The surgical resection of huge hepatocellular carcinoma (HCC) is still controversial. This study was designed to introduce our experience of liver resection for huge HCC and evaluate the safety and outcomes of hepatectomy for huge HCC. A total of 258 hepatic resections for the patients with huge HCC were analysed retrospectively from December 2002 to December 2011. The operative outcomes were compared with 293 patients with HCC >5.0 cm but huge HCC group and HCC >5.0 cm but huge HCC group has significantly a more longer overall and disease-free survival time than nodular huge HCC (P = 0.026, P = 0.022). Univariate and multivariate analysis revealed that the types of tumour, vascular invasion, and UICC stage were independent prognostic factors for overall survival (P = 0.047, P = 0.037, P = 0.033). Hepatic resection can be performed safely for huge HCC with a low mortality and favorable survival outcomes. Solitary huge HCC has the better surgical outcomes than nodular huge HCC.

    Natural disasters have enormous impacts on human society, especially on the development of the economy. To support decision-making in mitigation and adaption to natural disasters, assessment of economic impacts is fundamental and of great significance. Based on a review of the literature on economic impact evaluation, this paper proposes a new assessment model of the economic impacts of droughts by using the sugar industry in China as a case study, which focuses on the generation and transfer of economic impacts along a simple value chain involving only sugarcane growers and a sugar-producing company. A perspective of profit loss rate is applied to scale economic impact. By using "with and without" analysis, profit loss is defined as the difference in profits between disaster-hit and disaster-free scenarios. To calculate profit, analysis of a time series of sugar price is applied. With the support of a linear regression model, an endogenous trend in sugar price is identified and the time series of sugar price "without" disaster is obtained, using an autoregressive error model to separate impact of disasters from the internal trend in sugar price. Unlike the settings in other assessment models, representative sugar prices, which represent value level in disaster-free conditions and disaster-hit conditions, are integrated from a long time series that covers the whole period of drought. As a result, it is found that in a rigid farming contract, sugarcane growers suffer far more than the sugar company when impacted by severe drought, which may promote reflections among various economic bodies on economic equality related to the occurrence of natural disasters. Further, sensitivity analysis of the model built reveals that sugarcane purchase price has a significant influence on profit loss rate, which implies that setting a proper sugarcane purchase price would be an effective way of realizing economic equality in future practice of contract farming.

    In the aftermath of a disaster, the extent of the socioeconomic loss (fatalities, homelessness and economic losses) is often not known and it may take days before a reasonable estimate is known. Using the technique of socio-economic fragility functions developed (Daniell, 2014) using a regression of socio-economic indicators through time against historical empirical loss vs. intensity data, a first estimate can be established. With more information from the region as the disaster unfolds, a more detailed estimate can be provided via a calibration of the initial loss estimate parameters. In 2013, two main disasters hit the Philippines; the Bohol earthquake in October and the Haiyan typhoon in November. Although both disasters were contrasting and hit different regions, the same generalised methodology was used for initial rapid estimates and then the updating of the disaster loss estimate through time. The CEDIM Forensic Disaster Analysis Group of KIT and GFZ produced 6 reports for Bohol and 2 reports for Haiyan detailing various aspects of the disasters from the losses to building damage, the socioeconomic profile and also the social networking and disaster response. This study focusses on the loss analysis undertaken. The following technique was used:- 1. A regression of historical earthquake and typhoon losses for the Philippines was examined using the CATDAT Damaging Earthquakes Database, and various Philippines databases respectively. 2. The historical intensity impact of the examined events were placed in a GIS environment in order to allow correlation with the population and capital stock database from 1900-2013 to create a loss function. The modified human development index from 1900-2013 was also used to also calibrate events through time. 3. The earthquake intensity and the wind speed intensity was used from the 2013 events as well as the 2013 capital stock and population in order to calculate the number of fatalities (except in Haiyan), homeless and

    opinion were resolved at each stage. Studies were synthesised through a narrative review with full tabulation of the results of all included studies. In the economic model the analysis was developed for three patient populations, those with BMI > or = 40; BMI > or = 30 and or = 30 and costs and comorbidity. A total of 5386 references were identified of which 26 were included in the clinical effectiveness review: three randomised controlled trials (RCTs) and three cohort studies compared surgery with non-surgical interventions and 20 RCTs compared different surgical procedures. Bariatric surgery was a more effective intervention for weight loss than non-surgical options. In one large cohort study weight loss was still apparent 10 years after surgery, whereas patients receiving conventional treatment had gained weight. Some measures of QoL improved after surgery, but not others. After surgery statistically fewer people had metabolic syndrome and there was higher remission of Type 2 diabetes than in non-surgical groups. In one large cohort study the incidence of three out of six comorbidities assessed 10 years after surgery was significantly reduced compared with conventional therapy. Gastric bypass (GBP) was more effective for weight loss than vertical banded gastroplasty (VBG) and adjustable gastric banding (AGB). Laparoscopic isolated sleeve gastrectomy (LISG) was more effective than AGB in one study. GBP and banded GBP led to similar weight loss and results for GBP versus LISG and VBG versus AGB were equivocal. All comparisons of open versus laparoscopic surgeries found similar weight losses in each group. Comorbidities after surgery improved in all groups, but with no significant differences between different surgical interventions. Adverse event reporting varied; mortality ranged from none to 10%. Adverse events from conventional therapy included intolerance to medication, acute cholecystitis and gastrointestinal problems. Major adverse events following surgery, some

    We designed a new probabilistic algorithm, named PAGEC (probabilistic algorithm for genome comparison), which allowed a highly interactive study of long genomic strings. The comparison between two nucleic acid sequences is based on the creation of multiple index tables, which drastically reduces processing time for huge genomes, e.g. 13 min for a 4 Mb/4 Mb comparison. PAGEC lowered the need for memory when compared with other types of algorithm and took into account the low resolution of the final representation (paper or computer screen). Considering that standard printers permit a 300 d.p.i. resolution, the loss of computed information due to the probabilistic conception of the algorithm was not usually noticeable in the present study, mainly due to increased genomic sizes. Refinement was possible through an interactive zooming system, which enabled the visualization of the lexical base sequences of a considered part of both of the studied genomes. Biological examples of computation based on yeast and animal nucleic acid sequences presented in this paper reveal the flexibility of the PAGEC program, which is a valuable tool for genetic studies as it offers a solution to an important problem that will become even more important as time passes.

    利用环境经济学原理方法,借助ArcGIS9.3和统计分析工具,对延河流域土壤侵蚀主要经济损失进行定量评价,旨在为当地生态补偿和绿色GDP核算提供依据。结果表明:延河流域年土壤侵蚀经济损失总量达到38.52亿元,其中养分流失经济损失最多,占到总损失的94.73%,说明土壤侵蚀最直接、最严重的危害是导致土地生产力下降。延河流域的土壤侵蚀模数和单位面积土壤侵蚀经济损失大体均呈现从上游向下游递减的趋势。土地利用情况对土壤侵蚀经济损失的影响十分明显,主要表现为生态系统服务功能越完善,植被覆盖情况越好,土壤侵蚀经济损失越小。延河流域土壤侵蚀经济损失总量占到其GDP总量的17.49%,明显高于全国及陕西省平均水平,说明土壤侵蚀损失对该区域经济可持续发展的影响巨大。%Based on the principles and methods of environmental economics, the economic losses of soil erosion in the Yanhe River basin were estimated with ArcGIS 9.3. The results provided a basis for the green GDP accounting and ecological compensation policy for soil erosion. The total economic loss of soil erosion in the Yanhe River basin was 3. 852 billion Yuan per year. And the economic loss of nutrient losses was the biggest part of the total economic loss, which accounted for 94.73~ of the total. So the most direct and the most se- rious harm of soil erosion was the land productivity decline. The intensity of economic losses of soil erosion per unit area and soil erosion modules showed a decreasing trend from the upper reaches to the lower reaches of the Yanhe River. The land use influenced the economic loss of soil erosion obviously. The better the eco- system service function and the vegetation coverage were, the smaller the economic loss of soil erosion was. The ratio of economic losses of soil erosion to GDP was 17.49~ in the Yanhe River basin

    Full Text Available A 84-year-old white female had a brief loss of consciousness while playing bridge. A few minutes before the episode she had eaten pizza and significant amount of carbonated soft drinks. After recovery, her friends noticed that she was alert, but pale and sweating. Upon arrival at the emergency room, sitting blood pressure was 160/60 mmHg with a normal sinus rhythm. A chest X-Ray was performed, which was essential to make the diagnosis. The X-Ray showed a large retrocardiac opacity with air and liquid level compatible with a giant hiatus hernia. After a copious snack the hiatal hernia compressed the left atrium, decreasing the left cardiac output, elucidating the mechanism of the syncopal episode. In patients presenting with swallow syncope (particularly after a copious meal, validating the importance of a careful history, a chest X-Ray should be always be performed.

    Disaster loss estimation is a basis for managing risks and enacting scientific disaster prevention and miti- gation plans. In addition to direct economic loss, indirect economic loss is an important indicator to reflect the in- tensity of disasters and the socio-economic vulnerability. The more developed the economy, the higher interaction degree within the economic system, the greater vulnerability of the socio-economic system, and the larger indirect impact of the disasters. Indirect economic loss estimation is an indispensible part of disaster impact assessment, in which the estimation of indirect economic loss and recovery reconstruction period of each industrial sector is an im- portant basis for post-disaster reconstruction decision-making and risk management. Government policy makers and academic interests should pay more attention to the possible impact of the greater disasters on the local sustainable development, so as to prepare well for minimizing the adverse effects of the disasters.%灾害损失评估是灾害风险管理、科学防灾减灾规划的基础。除了直接经济损失外,间接经济损失是反映灾害影响强度及社会经济系统脆弱性的重要指标。经济越发达,经济系统关联程度越高,经济系统的脆弱性就越大,灾害间接经济影响也越大。已有研究表明,灾害间接经济损失往往与直接经济损失为同一量级,甚至是直接经济损失的数倍。间接经济损失评估是科学评价灾害影响不可或缺的组成部分,其中,产业部门间接经济损失和灾后恢复重建期的评估,可以为灾后恢复重建决策和防灾减灾规划提供有效的决策工具。政府决策者、学术界应重视灾害,特别是重大灾害(或巨灾)对地区经济长期可持续发展可能造成的影响,从而为减轻灾害的影响做好充分准备。

  3. Power Scaling of the Size Distribution of Economic Loss and Fatalities due to Hurricanes, Earthquakes, Tornadoes, and Floods in the USA

    Traditionally, the size of natural disaster events such as hurricanes, earthquakes, tornadoes, and floods is measured in terms of wind speed (m/sec), energy released (ergs), or discharge (m3/sec) rather than by economic loss or fatalities. Economic loss and fatalities from natural disasters result from the intersection of the human infrastructure and population with the size of the natural event. This study investigates the size versus cumulative number distribution of individual natural disaster events for several disaster types in the United States. Economic losses are adjusted for inflation to 2014 USD. The cumulative number divided by the time over which the data ranges for each disaster type is the basis for making probabilistic forecasts in terms of the number of events greater than a given size per year and, its inverse, return time. Such forecasts are of interest to insurers/re-insurers, meteorologists, seismologists, government planners, and response agencies. Plots of size versus cumulative number distributions per year for economic loss and fatalities are well fit by power scaling functions of the form p(x) = Cx-β; where, p(x) is the cumulative number of events with size equal to and greater than size x, C is a constant, the activity level, x is the event size, and β is the scaling exponent. Economic loss and fatalities due to hurricanes, earthquakes, tornadoes, and floods are well fit by power functions over one to five orders of magnitude in size. Economic losses for hurricanes and tornadoes have greater scaling exponents, β = 1.1 and 0.9 respectively, whereas earthquakes and floods have smaller scaling exponents, β = 0.4 and 0.6 respectively. Fatalities for tornadoes and floods have greater scaling exponents, β = 1.5 and 1.7 respectively, whereas hurricanes and earthquakes have smaller scaling exponents, β = 0.4 and 0.7 respectively. The scaling exponents can be used to make probabilistic forecasts for time windows ranging from 1 to 1000 years

    Full Text Available In most new commercial business software applications like Customer Relationship Management, the datais stored in the database layer which is usually a Relational Database Management System (RDBMS likeOracle, DB2 UDB or SQL Server. To access data from these databases, Structured Query Language (SQLqueries are used that are generated dynamically at run time based on defined business models and businessrules. One such business rule is visibility- the capability of the application to restrict data access based onthe role and responsibility of the user logged in to the application. This is generally achieved by appendingsecurity predicates in the form of sub-queries to the main query based on the roles and responsibility of theuser. In some cases, the outer query may be more restrictive while in other cases, the security predicatesmay be more restrictive. This often results in a dilemma for the cost-based optimizer (CBO of the backenddatabase whether to drive from the outer query or drive from the security predicate sub-queries. Thisdilemma is sometimes called the “Tiny-Huge, Huge-Tiny” problem and results in serious performancedegradation by way of increased response times on the application User Interface (UI. This paperprovides a case study of a new approach to vastly reduce this CBO dilemma by a combination of denormalizedcolumns and re-writing of the security predicates’ sub-queries at run-time, thereby levelling theouter and security sub-queries. This approach results in more stable execution plans in the database andmuch better performance of such SQLs, effectively leading to higher performance and scalability of theapplication.

    Destructive typhoon usually causes serious direct economic losses and restricts economic development. Through the establishment of economic losses assessment model,the relevant departments for disaster prevention and reduction could more easily make decisions. Based on the data of 40 typhoon disasters and historical data in Zhejiang Province during 1984-2007, this paper selected hazard risk, disaster environmental sensitivity, vulnerability of disaster bodies, and disaster prevention and mitigation capabilities as the four influencing factors to establish a direct economic losses assessment model with fuzzy comprehensive evaluation method. Correlation analysis result showed that the model had a high fitting rate with a correlation coefficient 0.806. For verification of the model, the data of three typhoons were used to make error analysis. The results showed that the analog values of the direct economic losses were basically in accord with the actual, and the simulation error was within a reasonable range. It is considered that the model established in this paper could reasonably evaluate the direct economic losses caused by typhoon disaster and give support to the decision-making of the government.%基于浙江省1984-2007年发生的40个台风数据及历史灾情数据,从致灾因子、孕灾环境、承灾体和防灾减灾4个方面选取影响因子,利用模糊综合评价方法建立直接经济损失模型,并对其进行验证。结果显示:该模型具有较高的拟合率,相关性系数达到0.806;基于3次台风过程数据进行模型验证和误差分析得知其模拟值与实际统计值基本一致,模拟误差在合理的范围之内;模型能够较好地评估一次台风灾害可能造成的直接经济损失,为政府部门的防灾减灾工作提供科学依据和决策支持,具有实际意义。

    It is challenging for neurosurgeons to remove huge tumors involving the skull that may possibly invade the dura or intracranial neural tissue. In this situation, excision of the tumor may cause profound blood loss, unexpected opening of the dura, or neurological injury. We describe a technique of craniotomy in a pediatric patient to avoid surgical complications. A 15-year-old boy had a huge metastatic calvarial Ewing's sarcoma. We removed the tumor successfully with modified concentric craniotomy. First, two oval burr holes are made on both sides of the tumor. The inner craniotomy uses the internal margin of the oval holes, while the outer cut uses the outer margins. The skull bone in between the two craniotomies is removed easily in two pieces and the dura surrounding the tumor can be exposed early in the procedure. In this way, the huge skull tumor can be removed en bloc under direct vision to avoid unwanted complications. Minimal blood and bone loss can be achieved. Blood transfusion was not necessary during the surgery. The patient did not have new neurological symptoms and signs after surgery. The goal of the modified concentric craniotomy is to develop an accessible margin of the dura surrounding the bulky tumor in the early phase of surgery. Blood and bone loss can be reduced significantly.

    Symptomatic or complicated liver cysts sometimes require surgical intervention and laparoscopic fenestration is the definitive treatment for these cysts. We performed minimally invasive surgery, hybrid natural orifice transluminal endoscopic surgery (NOTES) without scarring, for a huge liver cyst. An 82-year-old female presented with a month-long history of right upper abdominal pain. We diagnosed her condition as a huge liver cyst by morphological studies. She denied any history of abdominal trauma. Her serum CEA and CA19-9 were normal and a serum echinococcus serologic test was negative. Laparoscopic fenestration, using a hybrid NOTES procedure via a transvaginal approach, was performed for a huge liver cyst because we anticipated difficulty with an umbilical approach, such as single incision laparoscopic surgery (SILS). Her post-operative course was uneventful and she was discharged from our hospital three days after surgery. Pain killers were not required during and after hospitalization. No recurrence of the liver cyst or bulging was detected by clinical examination two years later. A recent trend of laparoscopic procedure has been towards minimizing the number of incisions to achieve less invasiveness. This hybrid NOTES, with a small incision for abdominal access, along with vaginal access, enabled painless operation for a huge liver cyst. We report a huge liver cyst treated by hybrid NOTES. This approach is safe, less invasive, and may be the first choice for a huge liver cyst. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

  14. Linking an economic model for European agriculture with a mechanistic model to estimate nitrogen losses from cropland soil in Europe

    Directory of Open Access Journals (Sweden)

    2007-07-01

    Full Text Available For the comprehensive assessment of the policy impact on greenhouse gas emissions from agricultural soils both socio-economic aspects and the environmental heterogeneity of the landscape are important factors that must be considered. We developed a modelling framework that links the large-scale economic model for agriculture CAPRI with the bio-geochemistry model DNDC to simulate greenhouse gas fluxes, carbon stock changes and the nitrogen budget of agricultural soils in Europe. The framework allows the ex-ante simulation of agricultural or agri-environmental policy impacts on wide range of environmental problems such as climate change (greenhouse gas emissions, air pollution and groundwater pollution. Those environmental impacts can be analysed in the context of economic and social indicators as calculated by the economic model. The methodology consists in four steps (i the definition of appropriate calculation units that can be considered as homogeneous in terms of economic behaviour and environmental response; (ii downscaling of regional agricultural statistics and farm management information from a CAPRI simulation run into the spatial calculation units; (iii setting up of environmental model scenarios and model runs; and finally (iv aggregating results for interpretation. We show first results of the nitrogen budget in cropland for the area of fourteen countries of the European Union. These results, in terms of estimated nitrogen fluxes, must still be considered as illustrative as needs for improvements in input data (e.g. the soil map and management data (yield estimates have been identified and will be the focus of future work. Nevertheless, we highlight inter-dependencies between farmer's choices of land uses and the environmental impact of different cultivation systems.

    An 85-year-old man complaining of vague abdominal discomfort was admitted to our hospital. A pulsatile 8 × 7-cm mass in the right upper abdomen was noticed on clinical examination. Computed tomography of the abdomen showed a huge arterial aneurysm in the right gastroepiploic artery, and the left gastroepiploic artery was meandering and expanding. An image diagnosis of gastroepiploic arterial aneurysm (GEAA) was made. Because of the huge size of the aneurysm and the predicted high risk of perforation, surgical intervention was planned. The aneurysm was identified in the greater curve and was found to adhere firmly to the transverse colon. Partial resection of the stomach, aneurysmectomy and partial resection of the transverse colon were performed. Clinically, splanchnic arterial aneurysms are rare. Among them, GEAA is especially rare. We report a rare case of a huge GEAA that was treated successfully by surgery. Published by Oxford University Press and JSCR Publishing Ltd. All rights reserved. © The Author 2015.

    Plunging ranula is a rare form of mucous retention cyst arising from submandibular and sublingual salivary glands, which may occasionally become huge occupying the whole of the floor of the mouth and extending into the neck, thus, restricting the neck movement as well as disfiguring the normal airway anatomy. Without fiberoptic assistance, blind or retrograde nasal intubation remains valuable choices in this type of situation. Here, we present a case of successful management of airway by blind nasal intubation in a patient posted for excision of a huge plunging ranula.

    Gastric teratoma is very rare tumor and usually presents in early infancy. An 8-year-old boy presented with a huge mass in abdomen extending from epigastrium to the pelvis. Ultrasound and CT scan of abdomen revealed a huge mass with solid and cystic components and internal calcifications. The preoperative diagnosis was a teratoma but not specifically gastric one. At operation, it was found to be gastric teratoma. The mass was excised completely with part of the stomach wall. The histopathology confirmed it to be mature gastric teratoma. The rarity of the teratoma with delayed presentation prompted us to report the case.

    Full Text Available Paediatric airway management is a great challenge even for an experienced anaesthesiologist. Difficult airway in huge cervical teratoma further exaggerates the complexity. This case report is intended at describing the intubation difficulties that were confronted during the airway management of a three year old girl presenting with huge neck teratoma and respiratory distress. This patient was successfully intubated with uncuffed endotracheal tubes in second attempt under inhalational anaesthesia with halothane and spontaneous ventilation. This case exemplifies the importance of careful preoperative workup of an anticipated difficult airway in paediatric patients with neck swelling to minimize any perioperative complications.

    We report an unusual granulomatous reaction of wear debris that produced a huge pelvic mass causing ureteral obstruction. A 72-year-old woman, who received a cemented total hip arthroplasty 30 years ago, was referred to the department of gynecology for examination of a pelvic mass. A computed tomography scan revealed a huge homogenous mass, measuring approximately 20 x 16 x 12 cm, including extensive osteolysis of the left pelvis around the acetabular component. Intravenous pyelogram revealed complete obstruction of the left ureter resulting in hydronephrosis of the left kidney. Histological examination from the biopsy specimen detected polyethylene wear debris in the mass.

    Full Text Available Introduction: Aim of this in vitro study is to evaluate the loss of tooth enamel after acid etching using a custom made profile projector (×100. Materials and Methods: Twenty human extracted maxillary and mandibular premolars were collected, and each tooth was mounted on an acrylic block (2 cm × 1 cm along with a 0.8 mm stainless steel wire partially embedded in acrylic in front of the buccal surface of the teeth. The 0.8 mm wire was used for reference; the image appeared on the projection screen was 80 mm implying that magnification ×100 has been achieved. Fabrication of custom made profile projector followed the principles of optics. Two projections of each sample before and after etching were projected. The projection was recorded using tracing paper. The difference between the two tracings before and after etching was measured using a millimeter scale. This reading was converted into microns, i.e., 1 mm = 10 μ. Results: The statistical method used for this study is a measure of central tendency. The research shows that the average enamel loss was around 15.25 microns. The median is a value at the midpoint of the group, and median for enamel loss is 15 μ. Mode for enamel loss is 15 μ that means most frequent or most repetitive enamel loss is 15 μ. The maximum enamel loss was 25 μ, and minimum of that was 10 μ. Conclusions: The results of this study indicate that etching enamel with 37% phosphoric acid for 30 s loses 15 μ of surface enamel using an economical and efficient custom made profile projector.

  3. Financing and budgetary impact of landslide losses for highways and urban infrastructures in NW Germany - an economic analysis using landslide database information and cost survey data

    Recent studies show that landslides cause even in low mountain areas of Central and Western Europe millions of dollars in annual losses (Klose et al., 2012; Vranken et al., 2013). The objective of this study has therefore been to model landslide disaster financing and to assess budgetary impacts of landslide losses for highways and urban infrastructures in the Lower Saxon Uplands, NW Germany. The present contribution includes two case studies on the financial burden of landslides for public budgets using the examples of the Lower Saxony Department of Transportation and the city of Hann. Münden. The basis of this research is a regional subset of a landslide database for the Federal Republic of Germany. Using a toolset for landslide cost modeling based on landslide databases (Klose et al., 2013), the direct costs of more than 30 landslide damage events to highways in a local case study area were determined. The annual average landslide maintenance, repair, and mitigation costs for highways in this case study area are estimated at 0.76 million between 1980 and 2010. Alternatively, a cost survey based on expert interviews has been conducted to collect landslide loss data for urban infrastructures. This cost survey for the city of Hann. Münden shows annual landslide losses of up to 3.4 million during the previous 10 years. Further expert interviews at city and highway agency level were focused on identifying procedure, resources, and limits of financing landslide damage costs. The information on landslide disaster financing and cost survey data on annual maintenance and construction budgets for highways, city sewer lines, and urban roads were used to evaluate the fiscal significance of estimated landslide losses. The results of this economic impact assessment prove variable financial burdens of analyzed public budgets. Thus, in costly years with landslide losses of more than 7 million, the Lower Saxony Department of Transportation is required to shift up to 19% of its

  4. Lessons about parks and poverty from a decade of forest loss and economic growth around Kibale National Park, Uganda.

    2011-08-23

    We use field data linked to satellite image analysis to examine the relationship between biodiversity loss, deforestation, and poverty around Kibale National Park (KNP) in western Uganda, 1996-2006. Over this decade, KNP generally maintained forest cover, tree species, and primate populations, whereas neighboring communal forest patches were reduced by half and showed substantial declines in tree species and primate populations. However, a bad decade for forest outside the park proved a prosperous one for most local residents. Panel data for 252 households show substantial improvement in welfare indicators (e.g., safer water, more durable roof material), with the greatest increases found among those with highest initial assets. A combination of regression analysis and matching estimators shows that although the poor tend to be located on the park perimeter, proximity to the park has no measureable effect on growth of productive assets. The risk for land loss among the poor was inversely correlated with proximity to the park, initial farm size, and decline in adjacent communal forests. We conclude the current disproportionate presence of poor households at the edge of the park does not signal that the park is a poverty trap. Rather, Kibale appears to provide protection against desperation sales and farm loss among those most vulnerable.

    The diagnosis and surgical treatment of 36 huge mediastinal tumors were summarized in order to evaluate the effect and safety of the operation. Thirty-six huge mediastinal tumor patients treated in our department from June 2006 to June 2013 were retrospective analyzed, of whom clinical manifestations, diagnosis, surgical treatment and prognosis were carefully collected. Twenty-three cases were men and 13 were women. The average age was 39.2 years old. The pathology turned out to be benign in 23 cases and malignant in 13 cases. Complete resection was achieved in 34 cases while palliative resection in 2 cases with no perioperative death. Six cases had developed postoperative complications but all recovered after active treatment. Patients who had been diagnosed with benign tumors were all alive after follow-up periods of 6 months to 7 years. Nine malignat tumor patients developed recurrence or metastasis, including seven deaths. Surgery played a vital role in the diagnosis and treatment of huge mediastinal tumors. Preoperative diagnosis, accurate surgical approach and careful operation were the key to successful treatment. Benign huge mediastinal tumors had excellent prognosis with surgery.

    Liposarcoma is the single most common soft tissue sarcoma. Because mediastinal liposarcomas often grow rapidly and frequently recur locally despite adjuvant chemotherapy and radiotherapy, they require complete excision. Therefore, the feasibility of achieving complete surgical excision must be carefully considered. We here report a case of a huge mediastinal liposarcoma resected via clamshell thoracotomy. A 64-year-old man presented with dyspnea on effort. Cardiomegaly had been diagnosed 6 years previously, but had been left untreated. A computed tomography scan showed a huge (36 cm diameter) anterior mediastinal tumor expanding into the pleural cavities bilaterally. The tumor comprised mostly fatty tissue but contained two solid areas. Echo-guided needle biopsies were performed and a diagnosis of an atypical lipomatous tumor was established by pathological examination of the biopsy samples. Surgical resection was performed via a clamshell incision, enabling en bloc resection of this huge tumor. Although there was no invasion of surrounding organs, the left brachiocephalic vein was resected because it was circumferentially surrounded by tumor and could not be preserved. The tumor weighed 3500 g. Pathologic examination of the resected tumor resulted in a diagnosis of a biphasic tumor comprising dedifferentiated liposarcoma and non-adipocytic sarcoma with necrotic areas. The patient remains free of recurrent tumor 20 months postoperatively. Clamshell incision provides an excellent surgical field and can be performed safely in patients with huge mediastinal liposarcomas.

  11. Global crop yield reductions due to surface ozone exposure: 1. Year 2000 crop production losses and economic damage

    Exposure to elevated concentrations of surface ozone (O 3) causes substantial reductions in the agricultural yields of many crops. As emissions of O 3 precursors rise in many parts of the world over the next few decades, yield reductions from O 3 exposure appear likely to increase the challenges of feeding a global population projected to grow from 6 to 9 billion between 2000 and 2050. This study estimates year 2000 global yield reductions of three key staple crops (soybean, maize, and wheat) due to surface ozone exposure using hourly O 3 concentrations simulated by the Model for Ozone and Related Chemical Tracers version 2.4 (MOZART-2). We calculate crop losses according to two metrics of ozone exposure - seasonal daytime (08:00-19:59) mean O 3 (M12) and accumulated O 3 above a threshold of 40 ppbv (AOT40) - and predict crop yield losses using crop-specific O 3 concentration:response functions established by field studies. Our results indicate that year 2000 O 3-induced global yield reductions ranged, depending on the metric used, from 8.5-14% for soybean, 3.9-15% for wheat, and 2.2-5.5% for maize. Global crop production losses totaled 79-121 million metric tons, worth $11-18 billion annually (USD 2000). Our calculated yield reductions agree well with previous estimates, providing further evidence that yields of major crops across the globe are already being substantially reduced by exposure to surface ozone - a risk that will grow unless O 3-precursor emissions are curbed in the future or crop cultivars are developed and utilized that are resistant to O 3.

The yearly maximum avoidable cost of CM at herd level was estimated at €14 504, corresponding to 6.9% of the net...... and the conventional modelling strategy, with the exception of the cost per case of CM. Similarities between the results obtained using the two methods were particularly evident when the mastitic cows' own yield level, had they not developed CM, was used as the reference for production in healthy cows when yield...

The diverticulum was mimicking with various cysts present in the lateral side of the female genital tract. Histopathological examination confirmed this to be a cervical diverticulum with communication to uterine cavity through two different openings. They can attain huge size if left ignored for long duration and present a diagnostic challenge to clinicians, radiologists, as well as pathologists because of its extreme rarity. Therefore, diverticula should also be included as a differential diagnosis. Its histopathological confirmation also highlights that diverticula can present as an acute abdomen, requiring early diagnosis with appropriate timely intervention. Immunohistochemistry CD 10 has also been used to differentiate it from a mesonephric cyst.

    The unitary moving mirror model is one of the best quantum systems for checking the reasoning of the firewall paradox in quantum black holes. The reasoning of Almheiri et al. inevitably raises a firewall paradox in the model. We resolve this paradox from the viewpoint of the energy cost of quantum measurements. No firewall with a deadly, huge energy flux appears, as long as the energy for the measurement is much smaller than the ultraviolet cutoff scale.

    The purpose of this study was to report an unusual case of severe microphthalmos, together with an orbital cyst and huge ocular surface dermolipoma. This is a clinical report relating clinical features as well as imaging and histopathologic findings, along with surgical management of the patient. A 5-month-old Chinese male infant was referred, with 2 large masses in the left eye that were present since birth. Ocular examination results revealed a complete absence of any eye structures in the left orbit. In its place were 2 large masses between the left upper and lower palpebral fissure. One was a 3 × 3 × 2.5-cm spherical red tumor with a smooth surface. The other was a large solid spherical tumor, 4 × 4 × 5 cm, covered with normal skin located in the temporal region and attached to the red mass by a pedicle. Orbital magnetic resonance imaging examination findings confirmed that no eye structures were present in the left orbit. However, a cystic lesion was found in the left orbit, with a low signal on T1-weighted imaging and high signal on T2-weighted imaging, and another huge spherical heterogeneous mass was located "outside" the left orbit. Anterior orbitotomy by conjunctival incision was performed under general anesthesia. A spherical cystic mass of 1.5 × 1.5 × 1.6 cm, a small eye of 0.7 × 0.7 × 0.6 cm, and a huge dermolipoma were removed completely. Pathologic examination results confirmed the diagnosis of severe microphthalmos, together with orbital dermoid cyst and dermolipoma. This rare case demonstrates that severe microphthalmos with a cyst may be completely covered by conjunctiva and associated with an unusually huge dermolipoma.

    Bezoars are rare causes of gastrointestinal obstruction. Basically, they are of four types: trichobezoars, phytobezoars, pharmacobezoars, and lactobezoars. Some rare types of bezoars are also known. In this article a unique case of plastic bezoars is presented. We describe a girl aged 14 years who ingested large amounts of plastic material used for knitting chairs and charpoys. The conglomerate of plastic threads, entrapped food material and other debris, formed a huge mass occupying the whole stomach and extended into small bowel.

    2015-01-01

    Giant left atria are defined as those measuring larger than 8 cm and are typically found in patients who have rheumatic mitral valve disease with severe regurgitation. Enlargement of the left atrium may create compression of the surrounding structures such as the esophagus, pulmonary veins, respiratory tract, lung, inferior vena cava, recurrent laryngeal nerve, and thoracic vertebrae and lead to dysphagia, respiratory dysfunction, peripheral edema, hoarse voice, or back pain. However, a huge left atrium is usually associated with rheumatic mitral valve disease but is very rare in a normally functioning prosthetic mitral valve, as was the case in our patient. A 46-year-old woman with a past medical history of mitral valve replacement and chronic atrial fibrillation was admitted to our hospital with a chief complaint of cough and shortness of breath, worsened in the last month. Physical examination showed elevated jugular venous pressure, respiratory distress, cardiac cachexia, heart failure, hepatomegaly, and severe edema in the legs. Chest radiography revealed an inconceivably huge cardiac sell-out. Transthoracic echocardiography demonstrated a huge left atrium, associated with thrombosis, and normal function of the prosthetic mitral valve. Cardiac surgery with left atrial exploration for the extraction of the huge thrombosis and De Vega annuloplasty for tricuspid regurgitation were carried out. The postoperative course was eventful due to right ventricular failure and low cardiac output syndrome; and after two days, the patient expired with multiple organ failure. Thorough literature review showed that our case was the largest left atrium (20 × 22 cm) reported thus far in adults with a normal prosthetic mitral valve function.

    Full Text Available Intravenous leiomyomatosis (IVL is a rare neoplasm characterized by histologically benign-looking smooth muscle cell tumor mass, which is growing within the intrauterine and extrauterine venous system. In this report we aimed to present an unusual case of IVL, which is originating from iliac vein and extended throughout to right cardiac chambers. A 49-year-old female patient, who was treated with warfarin sodium due to right iliac vein thrombosis, was admitted to our department with intermittent dyspnea, palpitation, and dizziness. Physical examination was almost normal except bilateral pretibial edema. On magnetic resonance venography, there was an intravenous mass, which is originated from right internal iliac vein and extended into the inferior vena cava. Transthoracic echocardiography and transesophageal echocardiography revealed a huge mass extending from the inferior vena cava through the right atrium, with obvious venous occlusion. Thoracic, abdominal, and pelvic MR showed an intravascular mass, which is concordant with leiomyomatosis. Surgery was performed through median sternotomy. A huge mass with 25-cm length and 186-gr weight was excised through right atrial oblique incision, on beating heart with cardiopulmonary bypass. Histopathologic assessment was compatible with IVL. Exact strategy for the surgical treatment of IVL is still controversial. We used one-stage approach, with complete resection of a huge IVL extending from right atrium to right iliac vein. In such cases, high recurrence rate is a significant problem; therefore it should be kept in mind.

    For huge hepatocellular carcinoma (HCC), therapeutic decisions have varied from local therapy to systemic therapy, with radiotherapy (RT) playing only a palliative role. In this study, we investigated whether multimodality treatment involving RT could be effective in huge HCC. This study was performed in 116 patients with HCC >10 cm. The number of patients in stage II, III and IV was 12, 54 and 50, respectively. RT was given as a combined modality in most patients. The median dose was 45 Gy, with 1.8 Gy per fraction. The median overall survival (OS) and progression-free survival (PFS) were 14.8 and 6.5 months, respectively. The median infield PFS was not reached. Infield failure, outfield intrahepatic and extrahepatic failure were observed in 8.6, 18.1, and 12.1% of patients, respectively. For OS and PFS, number of tumors, initial alpha-fetoprotein (AFP) level, treatment response, percent AFP decrement, and hepatic resection were significant prognostic factors. Tumor characteristics and treatment response were significantly different between long-term survivors and the other patients. Although huge HCC presents an aggressive clinical course, multimodality approaches involving RT can offer an opportunity for prolonged survival. © 2014 S. Karger AG, Basel.

    Intravenous leiomyomatosis (IVL) is a rare neoplasm characterized by histologically benign-looking smooth muscle cell tumor mass, which is growing within the intrauterine and extrauterine venous system. In this report we aimed to present an unusual case of IVL, which is originating from iliac vein and extended throughout to right cardiac chambers. A 49-year-old female patient, who was treated with warfarin sodium due to right iliac vein thrombosis, was admitted to our department with intermittent dyspnea, palpitation, and dizziness. Physical examination was almost normal except bilateral pretibial edema. On magnetic resonance venography, there was an intravenous mass, which is originated from right internal iliac vein and extended into the inferior vena cava. Transthoracic echocardiography and transesophageal echocardiography revealed a huge mass extending from the inferior vena cava through the right atrium, with obvious venous occlusion. Thoracic, abdominal, and pelvic MR showed an intravascular mass, which is concordant with leiomyomatosis. Surgery was performed through median sternotomy. A huge mass with 25-cm length and 186-gr weight was excised through right atrial oblique incision, on beating heart with cardiopulmonary bypass. Histopathologic assessment was compatible with IVL. Exact strategy for the surgical treatment of IVL is still controversial. We used one-stage approach, with complete resection of a huge IVL extending from right atrium to right iliac vein. In such cases, high recurrence rate is a significant problem; therefore it should be kept in mind.

    The city of Augusta is located in the southern part of the eastern coast of Sicily. Italian tsunami catalogue and paleo-tsunami surveys indicate that at least 7 events of tsunami affected the bay of Augusta in the last 4,000 years, two of which are associated with earthquakes (1169 and 1693) that destroyed the city. For these reasons Augusta has been chosen in the project ASTARTE as a test site for the study of issues related to tsunami hazard and risk. In last two years we studied hazard through the approach of the worst-case credible scenario and carried out vulnerability and damage analysis for buildings. In this work, we integrate that research, and estimate the damage to people and the economic loss of buildings due to structural damage. As regards inundation, we assume both uniform inundation levels (bath-tub hypothesis) and inundation data resulting from the worst-case scenario elaborated for the area by Armigliato et al. (2015). Human damage is calculated in three steps using the method introduced by Pagnoni et al. (2016) following the work by Terrier et al. (2012) and by Koshimura et al. (2009). First, we use census data to estimate the number of people present in each residential building affected by inundation; second, based on water column depth and building type, we evaluate the level of damage to people; third, we provide an estimate of fatalities. The economic loss is computed for two types of buildings (residential and trade-industrial) by using data on inundation and data from the real estate market. This study was funded by the EU Project ASTARTE - "Assessment, STrategy And Risk Reduction for Tsunamis in Europe", Grant 603839, 7th FP (ENV.2013.6.4-3)

    Digital pathology images are increasingly used both for diagnosis and research, because slide scanners are nowadays broadly available and because the quantitative study of these images yields new insights in systems biology. However, such virtual slides build up a technical challenge since the images occupy often several gigabytes and cannot be fully opened in a computer's memory. Moreover, there is no standard format. Therefore, most common open source tools such as ImageJ fail at treating them, and the others require expensive hardware while still being prohibitively slow. We have developed several cross-platform open source software tools to overcome these limitations. The NDPITools provide a way to transform microscopy images initially in the loosely supported NDPI format into one or several standard TIFF files, and to create mosaics (division of huge images into small ones, with or without overlap) in various TIFF and JPEG formats. They can be driven through ImageJ plugins. The LargeTIFFTools achieve similar functionality for huge TIFF images which do not fit into RAM. We test the performance of these tools on several digital slides and compare them, when applicable, to standard software. A statistical study of the cells in a tissue sample from an oligodendroglioma was performed on an average laptop computer to demonstrate the efficiency of the tools. Our open source software enables dealing with huge images with standard software on average computers. They are cross-platform, independent of proprietary libraries and very modular, allowing them to be used in other open source projects. They have excellent performance in terms of execution speed and RAM requirements. They open promising perspectives both to the clinician who wants to study a single slide and to the research team or data centre who do image analysis of many slides on a computer cluster.

    Full Text Available Due to the tremendous growth of data and large databases, efficient extraction of required data has become a challenging task. This paper propose a novel approach for knowledge discovery from huge unlabeled temporal databases by employing a combination of HMM and K-means technique. We propose to recursively divide the entire database into clusters having similar characteristics, this process is repeated until we get the cluster’s where no further diversification is possible. Thereafter, the clusters are labeled for knowledge extraction for various purposes.

    Full Text Available Paratubal cysts are asymptomatic embryological remnants. These cysts are usually diagnosed during adolescence and reproductive age. In general, their sizes are small but can be complicated by rupture, torsion, or hemorrhage. Paratubal cysts are often discovered fortuitously on routine ultrasound examination. We report a 19-year-old female patient who presented with irregular menses and abdominal pain. Ultrasound examination revealed a huge cystic mass at the right adnexial area. The diagnosis was confirmed as paratubal cyst during laporotomy and, hence, cystectomy and right salpingectomy were performed. [Cukurova Med J 2016; 41(3.000: 573-576

    A room acoustical model capable of modeling point sources, line sources, and surface sources is presented. Line and surface sources are modeled using a special ray-tracing algorithm detecting the radiation pattern of the surfaces of the room. Point sources are modeled using a hybrid calculation...... method combining this ray-tracing method with image source modeling. With these three source types it is possible to model huge and complex sound sources in industrial environments. Compared to a calculation with only point sources, the use of extended sound sources is shown to improve the agreement...

    production in 2030 due to the need to feed a growing population, our calculations of crop production and economic losses are conservative. Our results suggest that O3 pollution poses a growing threat to global food security even under an optimistic scenario of future ozone precursor emissions. Further efforts to reduce surface O3 concentrations and adapt crops to elevated O3 thus provide an excellent opportunity to increase global grain yields without the environmental degradation associated with additional fertilizer application or land cultivation.

    Full Text Available Abstract Cavernous hemangioma consists mainly of congenital vascular malformations present before birth and gradually increasing in size with skeletal growth. A small number of patients with cavernous hemangioma develop scoliosis, and surgical treatment for the scoliosis in such cases has not been reported to date. Here we report a 12-year-old male patient with severe progressive scoliosis due to a huge subcutaneous cavernous hemangioma, who underwent posterior correction and fusion surgery. Upon referral to our department, radiographs revealed a scoliosis of 85° at T6-L1 and a kyphosis of 58° at T4-T10. CT and MR images revealed a huge hemangioma extending from the subcutaneous region to the paraspinal muscles and the retroperitoneal space and invading the spinal canal. Posterior correction and fusion surgery using pedicle screws between T2 and L3 were performed. Massive hemorrhage from the hemangioma occurred during the surgery, with intraoperative blood loss reaching 2800 ml. The scoliosis was corrected to 59°, and the kyphosis to 45° after surgery. Seven hours after surgery, the patient suffered from hypovolemic shock and disseminated intravascular coagulation due to postoperative hemorrhage from the hemangioma. The patient developed sensory and conduction aphasia caused by cerebral hypoxia during the shock on the day of the surgery. At present, two years after the surgery, although the patient has completely recovered from the aphasia. This case illustrates that, in correction surgery for scoliosis due to huge subcutaneous cavernous hemangioma, intraoperative and postoperative intensive care for hemodynamics should be performed, since massive hemorrhage can occur during the postoperative period as well as the intraoperative period.

    Introduced in the late 90s, the active middle ear implant Vibrant Soundbridge (VSB) is nowadays used for hearing rehabilitation in patients with mild to severe sensorineural hearing loss (SNHL) unable to tolerate conventional hearing aids. In experienced hands, the surgical implantation is fast done, safe and highly standardized. Here, we present a systematic review, after more than 15 years of application, to determine the efficacy/effectiveness and cost-effectiveness, as well as patient satisfaction with the VSB active middle ear implant in the treatment of mild to severe SNHL. A systematic search of electronic databases, investigating the safety and effectiveness of the VSB in SNHL plus medical condition resulted in a total of 1640 papers. After removing duplicates, unrelated articles, screening against inclusion criteria and after in-depth screening, the number decreased to 37 articles. 13 articles were further excluded due to insufficient outcome data. 24 studies remained to be systematically reviewed. Data was searched on safety, efficacy and economical outcomes with the VSB. Safety-oriented outcomes included complication/adverse event rates, damage to the middle/inner ear, revision surgery/explant rate/device failure and mortality. Efficacy outcomes were divided into audiological outcomes, including hearing thresholds, functional gain, speech perception in quiet and noise, speech recognition thresholds, real ear insertion gain and subjective outcomes determined by questionnaires and patient-oriented scales. Data related to quality of life (QALY, ICER) were considered under economical outcomes. The VSB turns out to be a highly reliable and a safe device which significantly improves perception of speech in noisy situations with a high sound quality. In addition, the subjective benefit of the VSB was found to be mostly significant in all studies. Finally, implantation with the VSB proved to be a cost-effective and justified health care intervention.

    Big Data refers to the dynamic, large and disparate volumes of data comes from many different sources (tools, machines, sensors, mobile devices) uncorrelated with each others. It requires new, innovative and scalable technology to collect, host and analytically process the vast amount of data. Proper architecture of the system that perform huge data sets is needed. In this paper, the comparison of distributed and parallel system architecture is presented on the example of MapReduce (MR) Hadoop platform and parallel database platform (DBMS). This paper also analyzes the problem of performing and handling valuable information from petabytes of data. The both paradigms: MapReduce and parallel DBMS are described and compared. The hybrid architecture approach is also proposed and could be used to solve the analyzed problem of storing and processing Big Data.

    Full Text Available Lumbar disc herniation (LDH is the most common cause of sciatica and only in about 10% of the affected patients, surgical intervention is necessary. The side of the patient (the side of most prominent clinical complaints is usually consistent with the side of imaging (the side with most prominent disc herniation on imaging scans. In this case series, we presented our experience in four cases with huge intracanal LDH that a mismatch between the patient’s side and the imaging’s side was present. In these cases, for deciding to do the operation, the physicians need to rely more on clinical findings, but for deciding the side of discectomy, imaging characteristic (imaging side may be a more important criterion.

    HDSS (Huge Dense Linear System Solver) is a Fortran Application Programming Interface (API) to facilitate the parallel solution of very large dense systems to scientists and engineers. The API makes use of parallelism to yield an efficient solution of the systems on a wide range of parallel platforms, from clusters of processors to massively parallel multiprocessors. It exploits out-of-core strategies to leverage the secondary memory in order to solve huge linear systems O(100.000). The API is based on the parallel linear algebra library PLAPACK, and on its Out-Of-Core (OOC) extension POOCLAPACK. Both PLAPACK and POOCLAPACK use the Message Passing Interface (MPI) as the communication layer and BLAS to perform the local matrix operations. The API provides a friendly interface to the users, hiding almost all the technical aspects related to the parallel execution of the code and the use of the secondary memory to solve the systems. In particular, the API can automatically select the best way to store and solve the systems, depending of the dimension of the system, the number of processes and the main memory of the platform. Experimental results on several parallel platforms report high performance, reaching more than 1 TFLOP with 64 cores to solve a system with more than 200 000 equations and more than 10 000 right-hand side vectors.

    The glandular odontogenic cyst is a rare lesion described in 1987. It generally occurs at anterior region of mandible in adults over the age of 40 and has a slight tendency to recur. Histopathologically, a cystic cavity lined by a nonkeratinized, stratified squamous, or cuboidal epithelium varying in thickness is found including a superficial layer with glandular or pseudoglandular structures. A 21-year-old male visited Dankook University Dental Hospital with a chief complaint of swelling of the left posterior mandible. Radiographically, a huge multilocular radiolucent lesion involving impacted 3rd molar at the posterior mandible was observed. Buccolingual cortical expansion with partial perforation of buccal cortical bone was also shown. Histopathologically, this lesion was lined by stratified squamous epithelium with glandular structures in areas of plaque-like thickening. The final diagnosis was made as a glandular odontogenic cyst.

    A 75-year-old man had a history of triple vessel coronary artery disease. In August 2009, he had undergone successful percutaneous coronary intervention to the left circumflex coronary artery (LCX) for management of an in-stent restenosis (ISR) lesion. However, in September 2010, he began experiencing recurrent episodes of exertional chest pain. Chest radiography showed the left cardiac border bulging upwards. Transthoracic echocardiography and chest computed tomography revealed a huge oval mass of about 10.4 cm × 7.9 cm × 8.6 cm, which showed calcification and was obliterating the LCX. Subsequent coronary angiography revealed significant instent restenosis, with extravasation of a small amount of contrast material at the stent location, suggesting that the coronary artery had ruptured. We implanted a polytetrafluoroethylene-covered stent to seal the coronary perforation and to release the occlusion. The patient was symptom-free and had an uneventful outcome until the 1-year follow up. Coronary artery perforation; Covered stent; Hematoma.

    Full Text Available Abstract Background Mediastinal cysts compromise almost 20% of all mediastinal masses with bronchogenic subtype accounting for 60% of all cystic lesions. Although compression of adjoining soft tissues is usual, spinal complications and neurological symptoms are outmost rare and tend to characterize almost exclusively the neuroenteric cysts. Case presentation A young patient with intermittent, dull pain in his back and free medical history presented in the orthopaedic department of our hospital. There, the initial clinical and radiologic evaluation revealed a mediastinal mass and the patient was referred to the thoracic surgery department for further exploration. The following computed tomography (CT and magnetic resonance imaging (MRI shown a huge mediastinal cyst compressing the T4-T6 vertebral bodies. The neurological symptoms of the patient were attributed to this specific pathology due to the complete agreement between the location of the cyst and the nervous rule area of the compressed thoracic vertebrae. Despite our strongly suggestions for surgery the patient denied any treatment. Conclusion In controversy with the common faith that the spine plays the role of the natural barrier to the further expansion of cystic lesions, our case clearly indicates that, exceptionally, mediastinal cysts may cause severe vertebral complications. Therefore, early excision should be considered especially in young patients or where close follow up is uncertain.

    Introduction: Cardiac rhabdomyoma is type of benign myocardial tumor that is the most common fetal cardiac tumor. Cardiac rhabdomyomas are usually detected before birth or during the first year of life. They account for over 60% of all primary cardiac tumors. Case report: A 6 month old child with coughing and obstruction in breathing, was hospitalized in the Pediatric Clinic in UCCK, Pristine. The difficulty of breathing was heard and the pathological noise of the heart was noticed from the pediatrician. In the echo of the heart at the posterior and apico-lateral part of the left ventricle a tumoral mass was presented with the dimensions of 56 × 54 mm that forwarded the contractions of the left ventricle, the mass involved also the left ventricle wall and was not vascularized. The right ventricle was deformed and with the shifting of the SIV on the right the contractility was preserved. Aorta, the left arch and AP were normal with laminar circulation. The pericard was presented free. Radiography of thoracic organs was made; it resulted on cardiomegaly and significant bronchovascular drawing. It was completed with an MRI and it resulted on: Cardiomegaly due to large tumoral mass lesion (60×34 mm) involving lateral wall of left ventricle. It was isointense to the muscle on T1W images, markedly hyperintense on T2W images. There were a few septa or bant like hypointensities within lesion. On postcontrast study it showed avid enhancement. The left ventricle volume was decreased. Mild pericardial effusion was also noted. Surgical intervention was performed and it resulted on the histopathological aspect as a huge infantile rhadbomyoma. Conclusion: In most cases no treatment is required and these lesions regress spontaneously. Patients with left ventricular outflow tract obstruction or refractory arrhythmias respond well to surgical excision. Rhabdomyomas are frequently diagnosed by means of fetal echocardiography during the prenatal period. PMID:27147810

    Ground-motion variability, which was used in the probabilistic seismic hazard analysis (PSHA) in computing annual exceedence probability, is composed of random variability (aleatory uncertainty) and model uncertainty (epistemic uncertainty). Finding random variability of ground motions has become an important issue in PSHA, and only the random variability can be used in deriving the annual exceedence probability of ground-motion. Epistemic uncertainty will be put in the logic tree to estimate the total uncertainty of ground-motion. In the present study, we used about 18,859 records from 158 shallow earthquakes (Mw > 3.0, focal depth ≤ 35 km, each station has at least 20 records) form the Taiwan Strong-Motion Instrumentation Program (TSMIP) network to analyse the random variability of ground-motion. First, a new ground-motion attenuation model was established by using this huge data set. Second, the residuals from the median attenuation were analysed by direct observation on inter-event variability and site-specific variability. Finally, the single-path variability was found by a moving-window method on either single-earthquake residuals or single-station residuals. A variogram method was also used to find minimum variability for intra-event residuals and inter-event residuals, respectively. Results reveal that 90% of the single-path sigma σSP are ranging from 0.219 to 0.254 (ln unit) and are 58% to 64% smaller than the total sigma (σT =0.601). The single-site sigma (σSS) are also 39%-43% smaller. If we use only random variability (single-path sigma) in PSHA, then the resultant hazard level would be 28% and 25% lower than the traditional one (using total sigma) in 475-year and in 2475-year return period, respectively, in Taipei.

    We present a case of an 87-year-old male patient with a huge ascending aortic aneurysm, filled by a huge thrombus most probably due to previous dissection. This finding was detected by two-dimensional transthoracic echocardiography and contrast-enhanced computed tomography (CT) angiography scan. The patient refused surgical treatment and was medically treated. Despite the huge and mobile intraluminal thrombus, the patient remained embolic event-free up to 6 years later, and this makes the case unique.

    The value of hepatic resection (HR) for huge hepatocellular carcinomas (HCC) (≥ 10 cm in diameter) remains controversial. The aim of this study is to evaluate the efficacy of hepatic resection (HR) for patients with huge HCC. A total of 739 patients with huge HCC (≥ 10 cm in diameter) (huge HCC group, n = 244) or small HCC (huge HCC were identified based on Cox regression analyses. The hospital mortality of these two groups were similar (P = 0.252). The 5-year OS of huge HCC group and small HCC group were 30.3% and 51.9%, respectively (P huge HCC had a significant higher 5-year OS (50.6%) than mutinodular huge HCC (26.9%) (P = 0.016). Multivariate analysis revealed that uninodular huge HCC and absence of PVTT independently predicted better OS for huge HCC patients. HR is a safe and effective approach for the treatment of huge HCC, especially for the uninodular subtype.

    Full Text Available The importance of medical devices in everyday users/patients lives is imensse. This is the reason why emphasis must be put on safety during their use. Satisfactory safety level can be achived by implementation of quality and risk management standards. Medical device manufacturers must learn to deal with the potential risks by using theoretical and practical examples and measures in order to protect their users/patients and themselves from suffering huge losses arising from adverse events or recall of their products. The best moment for implementation of risk management methods and analysis begins from the device design and development through manufacturing, sales and distribution. These way medical device manufacturers will succseed in protecting their users/patients from serious adverse events and at the same time protect their brand and society status, while minimizing economic losses.

    The simulation of climate data tends to produce very large data sets, which hardly can be processed in classical post-processing visualization applications. Within the most traditional post-processing scenarios the visualization pipeline consisting of the processes data generation, visualization mapping and rendering is distributed into two parts over the network or separated via file transfer: the data generation on a supercomputer on the one hand and the other tasks on a special visualization system on the other hand. That way either temporary data sets with huge volume have to be transferred over the network, which leads to bandwidth bottlenecks and volume limitations. As an alternative all simulation and visualization processes are integrated in a monolithic application, where just 2D pixel data is stored, which reduces the user's possibilities for 3D interaction with visualization to frame skipping. Within the Climate Visualization Lab - as part of the Cluster of Excellence "Integrated Climate System Analysis and Prediction" (CliSAP at the University of Hamburg, in cooperation with the German Climate Computing Center (DKRZ) - we plan to integrate a different approach, which has been proven to be successful in former meteorology applications, e.g. PALM (Parallel Large Eddy Simulation Model). Our software framework DSVR is based on the separation of the process chain between the mapping and the rendering processes. We have developed a parallelized visualization library based on MPI and evaluated on various supercomputers. DSVR can be used to integrate the visualization into a parallel simulation model to support in-situ processing, resulting in a sequence of time-based geometric 3D objects which can be interactively rendered in a separate 3D viewer application. To meet the actual requirements (a) to visualize existing data sets, (b) to support more than rectilinear grids, and (c) to integrate in-situ processing in the ICON model, all based on our DSVR framework

    Full Text Available A comprehensive assessment of policy impact on greenhouse gas (GHG emissions from agricultural soils requires careful consideration of both socio-economic aspects and the environmental heterogeneity of the landscape. We developed a modelling framework that links the large-scale economic model for agriculture CAPRI (Common Agricultural Policy Regional Impact assessment with the biogeochemistry model DNDC (DeNitrification DeComposition to simulate GHG fluxes, carbon stock changes and the nitrogen budget of agricultural soils in Europe. The framework allows the ex-ante simulation of agricultural or agri-environmental policy impacts on a wide range of environmental problems such as climate change (GHG emissions, air pollution and groundwater pollution. Those environmental impacts can be analyzed in the context of economic and social indicators as calculated by the economic model. The methodology consists of four steps: (i definition of appropriate calculation units that can be considered as homogeneous in terms of economic behaviour and environmental response; (ii downscaling of regional agricultural statistics and farm management information from a CAPRI simulation run into the spatial calculation units; (iii designing environmental model scenarios and model runs; and finally (iv aggregating results for interpretation. We show the first results of the nitrogen budget in croplands in fourteen countries of the European Union and discuss possibilities to improve the detailed assessment of nitrogen and carbon fluxes from European arable soils.

    The dielectric properties of polyimide/boron nitride (PI/BN) nanocomposite films are investigated as a function of the BN nanofiller size from 20 to 350 °C and at low filler content (1-2 vol.%). The role of the BN nanofiller size on the large reduction of the electrode polarization relaxation phenomenon due to ionic movements is reported. For the two smallest BN nanoparticles (95 nm and 35 nm), the permittivity, dielectric losses and dc conductivity are strongly attenuated above 200 °C by a factor of 10 to 1000 compared to neat PI. Thus, the dc conductivity at 350 °C is reduced from 4   ×   10-8 Ω-1 cm-1 for neat PI to 3   ×   10-11 Ω-1 cm-1 for PI/BN (35 nm). Moreover, a further decrease is obtained by functionalizing the nanofiller surface with a silane coupling agent which improves the grafting of PI chains on those latter nanoparticles. These results highlight the trapping efficiency in the interphase region introduced by the small BN nanofillers (<100 nm) and provides evidence as to the huge nanodielectric effects on the charge carrier transport controlled by the nanoparticle diameter. This finding should be of great importance for advanced high temperature electrical insulation in the future.

    Patients with huge hepatocellular carcinoma >10 cm in diameter represent a special subgroup for treatment. To date, there are few data and little consensus on treatment strategies for huge hepatocellular carcinoma. In this study, we summarized the effects and safety of transarterial chemoembolization for huge hepatocellular carcinoma. A retrospective study was performed based on a large cohort of patients (n = 511) with huge hepatocellular carcinoma who underwent serial transarterial chemoembolization between January 2008 to December 2011 and were followed up until March 2013. We found median survival time was 6.5 months. On multivariate analysis, Child-Pugh class (A versus B) (p huge hepatocellular carcinoma and is recommended as a component of combination therapy. In addition, patients with good liver function and low alpha-fetoprotein levels may acquire greater survival benefits from transarterial chemoembolization.

    This study compares the perceptions of producers and veterinarians on the economic impacts of Mycobacterium avium subspecies paratuberculosis (MAP) infection in cow-calf herds. Questionnaires were mailed to beef producers through the Designated Johne's Coordinators and to veterinarians belonging to a nationwide professional organization. Important components of losses associated with MAP infected cows were used to estimate total loss per infected cow-year using an iterative approach based on collected survey data. Veterinarians were more likely to perceive a lower calving percentage in MAP infected cows compared to producers (P=0.02). Income lost due to the presence of Johne's disease (JD) in an infected cattle herd was perceived to be higher by veterinarians (Pveterinarians without JD certification, seedstock producers were more likely to perceive genetic losses due to culling cows positive for MAP (Pveterinarians was $250 ($82-$486). Mean annual loss due to JD in a 100 cow herd with a 7% true prevalence was $1644 ($625-$3250) based on information provided by producers. Similarly, mean annual loss based on information collected from veterinarians was $1747 ($575-$3375). Copyright © 2013 Elsevier B.V. All rights reserved.

    Full Text Available Background & objectives: To examine the household economic impact of an outbreak of chikungunya in terms of out-of-pocket health care expenditure and income foregone due to loss of productive time in Orissa, India.Methods: Structured interviews were conducted on 150 respondents, bread winners from the affected households of a village with maximum number of reported cases in the state, during August 2007. We looked at the economic profile, treatment history, and patient-side cost of care, loss of productivity and consequent income loss.Results: The median out-of-pocket health care expenditure was US$ 84, of which the proportion of cost of diagnosis was the highest (US$ 77. One hundred and forty nine respondents incurred cost of care more than 10% of their monthly household income (catastrophic health expenditure. The median catastrophic health care expenditure was 37%. The respondents depended more on private health care providers (49% and 31% of them accessed care from both public and private health care providers. The median work days lost was 35 with a consequent loss of income of US$ 75.Interpretation & conclusion: Outbreak of an emerging disease creates unforeseen catastrophic health care expenditure and reinforcing the poverty ill-health nexus. The priorities of tackling emerging diseases should include; discretionary public health spending, financial protection against the cost of illness and productivity with special emphasis on people living on daily wages with less financial reserves, and further research on therapeutic measures to reduce the duration of suffering and consequent economic loss.

    Full Text Available Given the growing importance of integrating marketing and operations indicators to enhance business performance, and the availability of sophisticated geospatial statistical techniques, this paper draws on these concepts to develop an indicator of propensity to energy commercial losses. Loss management is a strategic topic among energy distribution companies, in particular for AES Eletropaulo. In such context, this work’s objectives are: (i to appropriate spatial auto-regressive models and geographically weighted regression (GWR in measuring the cultural influence of neighborhood in customer behavior in the energy fraud act; (ii to replace slum coverage areas by a regional social vulnerability index; and (iii to associate energy loss with customer satisfaction indicators, in a spatial-temporal approach. Spatial regression techniques are revised, followed by a discussion on social vulnerability and customer satisfaction indicators. Operational data obtained from AES Eletropaulo’s geographical information systems were combined with secondary data in order to generate predictive regression models, having energy loss as the response variable. Results show that the incorporation of market and social oriented data about customers substantially contribute to explicate energy loss – the coefficient of determination in the regression models rose from 17.76% to 63.29% when the simpler model was compared to the more complex one. Suggestions are made for future work and opportunities for the replication of the methodology in comparable contexts are discussed.

    Full Text Available A study was carried out in Manas National Park, Assam in northeastern India between 2007 and 2009 to understand the magnitude of human-elephant conflict through a quantification of damage and assessment of economic loss. A cluster of six villages adjacent to the Park was selected for this study. Five major agricultural crops were grown during the study period of which three were raided by elephants: winter paddy, autumn paddy and pulses. Paddy was the principle crop central to the farmers’ subsistence. Winter paddy was the most cultivated crop and autumn paddy was the least cultivated. The incidence rate of crop raiding was highest for autumn paddy and lowest for pulses. Overall economic loss due to crop raiding was negligible, however at the individual farmer level, it was quite high. The study revealed that human-elephant conflict is not so severe, indicating ample opportunity for human-elephant coexistence in the region. Crop fields adjacent to the Park were particularly vulnerable to crop raiding which necessitates creation of a buffer zone. The frequency of raiding and the extent of damage was found to be significantly less in crop fields which were guarded by farmers. This was due to traditional crop guarding practices being followed in the region, the strengthening of which could effectively reduce annual crop loss and thus human-elephant conflict could be minimized to a large extent.

    To investigate the surgical outcome of combined posterior and anterior approaches for the resection of thoracolumbar spinal canal huge dumbbell-shaped tumor. Between January 2009 and March 2015, 12 patients with thoracolumbar spinal canal huge dumbbell-shaped tumor were treated by posterior approach and anterolateral approach through diaphragmatic crura and thoracoabdominal incision for complete resection. There were 9 males and 3 females, with an average age of 45 years (range, 30-65 years). The disease duration was 8-64 weeks (mean, 12.7 weeks). The tumor was located at T(12), L1 in 6 cases, at L(1,2) in 5 cases, and at L(2,3) in 1 case. The tumor size ranged from 4.3 cm x 4.0 cm x 3.5 cm to 7.5 cm x 6.3 cm x 6.0 cm. According to tumor outside the spinal involvement scope and site and based on the typing of Eden, 5 cases were rated as type b, 2 cases as type d, 4 cases as type e, and 1 case as type f in the transverse direction; two segments were involved in 8 cases, and more than two segments in 4 cases. The degree of tumor excision, tumor recurrence, and the spine stability were observed during follow-up. The verbal rating scale (VRS) was used to evaluate pain improvement. The average surgical time was 170 minutes (range, 150-230 minutes); the average intraoperative blood loss was 350 mL (range, 270-600 mL). All incisions healed by first intention, and no thoracic cavity infection and other operation related complication occurred. Of 12 cases, 10 were histologically confirmed as schwannoma, and 2 as neurofibroma. The patients were followed up 6 months to 6 years (mean, 31 months). Neurological symptoms were significantly improved in all patients, without lower back soreness. The thoracolumbar X-ray film and MRI showed no tumor residue. No tumor recurrence, internal fixator loosening, scoliosis, and other complications were observed during follow-up. VRS at last follow-up was significantly improved to grade 0 (10 cases) or grade 1 (2 cases) from preoperative

    Flexible electricity consumption has potential to become an important step towards achieving an economically efficient electricity supply. One way to obtain flexible electricity consumption is to establish agreements with private consumers regarding power-cuts during periods of peak consumption. Whether these agreements are economically efficient depends on how big a welfare loss the consumers experience during controlled power-cuts. This loss has so far not been estimated; hence the objective of this rapport is to indicate the level of such welfare loss. This rapport aims to analyse and quantify the private consumer's preferences for a number of characteristics relating to 'controlled power-cuts' of washing machine, dish-washer and dry-tumbler respectively. These characteristics are decisive factors in determining loss of utility the consumer associate with the power-cuts. Additionally, these characteristics are significant for the application of power-cuts. The selected characteristics investigated are duration and frequency. The consumers required compensation for acceptance of changes to the various characteristics is derived. (A combination of number of power cuts per year with a given duration is to be considered as an agreement) Data was collected through questionnaires and analysed using Discrete Choice Experiment. This method is based on the consumers choice between various combinations of controlled power-cut agreements. Apart from providing the possibility to value a change to each of the specified characteristics, the method can also estimate a total value of a changed agreement. The survey shows that the consumers experience an increasing welfare loss the longer duration of the power-cuts and the greater the frequency. Preferences and compensation for the various agreements are shown not to be dependent on whether the consumer has received information regarding the environmental benefits of the agreement. A lower compensation threshold

    Economic losses incurred by Przhevalskiana silenus in goats of Jammu province of Jammu and Kashmir (North India) were assessed from July 2005 to June 2006. Abattoir studies revealed holes in hides for 112 days (mid-December 2005 to first week of April 2006) and trimming of carcass for 243 days (July 2005 to February 2006) during a lifecycle, leading to annual losses of Rs. 7,391,432 and Rs. 10,510,837, respectively. An effect on production traits (weight gain and milk) was assessed on naturally P. silenus-infested Beetal goats. The mean body weight loss of warbled goats was 2.40 kg (equal to 1.096 kg of meat, assuming 45.7% dressing percentage of goat) leading to an annual loss of Rs. 35,473,265. The mean milk yield loss per warbled goat per day was 101.7 g resulting in losses to the tune of Rs. 19,879,012. It can be concluded that P. silenus infestation resulted in an overall loss of Rs. 73,254,547, i.e. 73.26 million annually (equivalent to US $1.62 million; US $1 = Rs. 45.24), where reduced growth alone contributed 49% of the total losses. A study recommends that a control scheme against P. silenus infestation in goats using an effective insecticide should be followed to prevent huge economic losses in hide, milk and meat production. Economic losses associated with P. silenus infestation in goats were estimated for the first time from India.

    Mucinous cystadenoma (MC) of the ovary is an unilateral, multilocular cystic benign epithelial tumor. Supposed to be hormone responsive, MC reaches huge sizes during pregnancy. Aortocaval compression is common during pregnancy, especially when the pregnant woman is in the supine position. However, the compression recovers with a change in position. The authors report the first case of a huge mucinous cystadenoma of the ovary complicating pregnancy and causing virilization, premature labor, and persistent supine hypotensive syndrome.

    The traditional open surgery, for the treatment of huge tumor in the narrow space of pelvic cavity and in close proximity to pelvic organs and neurovascular structures, is very difficult and challenging. We report a case of huge neurilemmoma operated using the robot-assisted laparoscopy. We used interventional pre-operation embolization to control blood supply of tumor because MRI showed the tumor had a sufficient blood supply.

    That the current economic crisis is having an impact on population health and healthcare utilisation across Europe is fairly established; how national health systems and markets are reacting is however still poorly understood. Drawing from the economic literature we conducted 21 interviews with physicians, policy-makers and healthcare managers in Portugal, to explore their perceptions on the impact of the crisis on the country's market medical services, on physicians' motivation, and the ensuing coping strategies. Interviews were recorded, transcribed and analysed using NVivo software. We show that despite the crisis, few physicians reported considering leaving the public sector and the country, and very diverse coping strategies are emerging, depending on the respective employment institutions and seniority. In spite of the changes in patient case-mix, demand for medical services may not have necessarily increased, having shifted from public to private, with many highlighting the contribution of the current crisis in consolidating the private sector. In order to maintain their pre-crisis living standards amidst deteriorating salaries and increasing controls, hospital physicians have resorted to strategies such as shifting hours to the private, and primary care ones to anticipating their retirement. Migration was reported to be an option only for the younger and older doctors. Our study suggests the existence of resilience among Portuguese physicians and in the country's market for medical services, which, if corroborated by further research, will need to be taken into account by national health policies.

    Full Text Available Background: Road traffic accidents, considered as global tragedies, are in increasing trend however, the safety situation is very severe in developing countries incurring substantial amount of human, economic and social costs. Motorcycle crashes, the commonest form, occur mostly on economically active population. However, there is limited coverage of studies on economic burden of motorcycle crashes. This study aims to estimate the total cost and DALYs lost due to motorbike accidents among victims of Kathmandu Valley.Materials and Methods: Retrospective cross-sectional study was conducted among the patients having history of motorbike accidents within past twelve months and at least 3 months from the date of data collection. Interview was conducted using proforma among 100 victims of accidents and their care giver in case of death from November 15, 2014 to May 15, 2015. Cost estimation of motorbike accident was done based on human capital approach. Data collection tool was pretested and collected data were analyzed by SPSS and Microsoft excel. Results: Males (79% belonging to the economically productive age group shared the highest proportion among total accidents victims. Most common reason for accidents was reported to be poor road condition (41%. Indirect cost was found to be significantly higher than direct costs highlighting its negative impact on economy of family and nation due to productivity loss. Total Disability Adjusted Life Years (DALYs lost per person was found to be 490 years and national estimation showed large burden of motorbike accidents due to huge DALY loss.Conclusions: For low resource countries like Nepal, high economic costs of motorbike accidents can pose additional burden to the fragile health system. These accidents can be prevented, and their consequences can be alleviated. There is an urgent need for reinforcement of appropriate interventions and legislation to decrease the magnitude of it and its associated grave

    To evaluate the relationship between chronic renal failure (CFR) defined through HUGE (hematocrit, urea and gender) formula score and the patient's cardiovascular risk measured through cardiovascular disease antecedents such as ischemic cardiopathy, cerebrovascular disease and peripheral arterial disease. The sample consisted of 2,831 subjects. Mean age was 51.2±14.7 years and 53.5% were female. Serum creatinine, urea, hematocrit and 24h proteinuria were analyzed. HUGE score was calculated from gender, urea and hematocrit. GFR was estimated from uncalibrated serum creatinine using the abbreviated Modification of Diet in Renal Disease equation (MDRD-4). UAE was measured in first morning urine sample. Using HUGE formula 2.2% (n = 61) of subjects had CRF. Of them, 12 (19.7%) had cardiovascular disease history. Among patients without CRF (n = 2770), 194 subjects had history of previous cardiovascular diseases (0.07%; p HUGE definition of CRF was 3.25 (p = 0.001, Mantel-Haenszel test). CFR was associated to higher pulse pressure (PP) and increased urinary albumin excretion. A significant cardiovascular risk was associated to the diagnosis of CRF through HUGE formula. This relation was closer than the obtained using MDRD estimated GFR in spite of a bigger sample. HUGE formula seems to be a useful tool for diagnosing CRF and evaluate the cardiovascular risk of these patients.

  20. Weeds Cause Losses in Field Crops through Allelopathy

    Directory of Open Access Journals (Sweden)

    Tasawer ABBAS

    2016-03-01

    Full Text Available A large number of weeds are known to be associated with crops and causing economic losses. Weeds interfere with crops through competition and allelopathy. They produce secondary metabolites known as allelochemicals, which belong to numerous chemical classes such as phenolics, alkaloids, fatty acids, indoles, terpens etc. However, phenolics are the predominant class of allelochemicals. The allelochemicals release from weed plants takes place through leaf leachates, decomposition of plant residues, volatilization and root exudates. Weeds leave huge quantities of their residues in field and affect the associated, as well as succeeding crops, in various cropping systems. Liberation of allelochemicals from weeds affects the germination, stand establishment, growth, yield and physiology of crop plants. They cause substantial reduction in germination and growth of the crop plants by altering various physiological processes such as enzyme activity, protein synthesis, photosynthesis, respiration, cell division and enlargement, which ultimately leads to a significant reduction in crop yield. In crux, allelopathic weeds represent a potential threat for crop plants and cause economic losses.

    We consider a test of the Copernican Principle through observations of the large-scale structures, and for this purpose we study the self-gravitating system in a relativistic huge void universe model which does not invoke the Copernican Principle. If we focus on the the weakly self-gravitating and slowly evolving system whose spatial extent is much smaller than the scale of the cosmological horizon in the homogeneous and isotropic background universe model, the cosmological Newtonian approximation is available. Also in the huge void universe model, the same kind of approximation as the cosmological Newtonian approximation is available for the analysis of the perturbations contained in a region whose spatial size is much smaller than the scale of the huge void: the effects of the huge void are taken into account in a perturbative manner by using the Fermi-normal coordinates. By using this approximation, we derive the equations of motion for the weakly self-gravitating perturbations whose elements have relative velocities much smaller than the speed of light, and show the derived equations can be significantly different from those in the homogeneous and isotropic universe model, due to the anisotropic volume expansion in the huge void. We linearize the derived equations of motion and solve them. The solutions show that the behaviors of linear density perturbations are very different from those in the homogeneous and isotropic universe model.

    Prediction of inundation loss can provide important reference for flood control planning. Base on GIS, the digital elevation model was built, and the the submerged area of Harbin city was simulated under condition that the water level of Songhua River reached to 120.89 m by plane simulation method. The spatial information of urban land use and the spatial distribution of the socio-economic information in Harbin city were acquired by combining GIS with RS technology, and the direct and indirect economic losses were forecasted on agriculture, industry, tertiary industry, rural and urban housing and family wealth in the submerged area. The results showed that when the water level of Songhua River reached 120.89 m, the submerged area which including the Songbei area, Hulan area, Daowai area, Daoli area, Xiangfang area in Harbin would be 1 402 km2, and the total economic loss was 6.82 billion Yuan. Songbei was the most severe submerged area with biggest total economic loss especially on agriculture, industry, tertiary industry and rural residential family wealth. Daoli area and Daowai area had the most severe loss area with urban housing and family wealth, and their economic loss rate per unit area was also higher, so they were the focus of Harbin city for flood control. Hulan area and the Songbei area had the lowest rate of economic loss per unit area, so it could be considered as flood zoon. Spatial layout of parts of industrial land in Songbei area, Hulan area and Daowai area and parts of urban residential land in Daowai area, Daoli area and Xiangfang area was unreasonable.%利用地理信息系统预测洪水造成的经济损失,可以为防洪规划提供重要的依据.本文基于地理信息系统GIS技术构建数字高程模型,采用平面模拟方法模拟了松花江水位达到120.89 m时哈尔滨市各区的淹没范围,运用地理信息系统GIS与遥感RS技术相结合的方法获取了哈尔滨市区土地利用现状空间分布信息,并用其将

  3. Impact of Climate Conditions on Occupational Health and Related Economic Losses: A New Feature of Global and Urban Health in the Context of Climate Change.

    One feature of climate change is the increasing heat exposure in many workplaces where efficient cooling systems cannot be applied. Excessive heat exposure is a particular problem for working people because of the internal heat production when muscle work is carried out. The physiological basis for severe heat stroke, other clinical effects, and heat exhaustion is well known. One feature of this health effect of excessive workplace heat exposure is reduced work capacity, and new research has started to quantify this effect in the context of climate change. Current climate conditions in tropical and subtropical parts of the world are already so hot during the hot seasons that occupational health effects occur and work capacity for many working people is affected. The Hothaps-Soft database and software andClimateCHIP.orgwebsite make it possible to rapidly produce estimates of local heat conditions and trends. The results can be mapped to depict the spatial distribution of workplace heat stress. In South-East Asia as much as 15% to 20% of annual work hours may already be lost in heat-exposed jobs, and this may double by 2050 as global climate change progresses. By combining heat exposure data and estimates of the economic consequences, the vulnerability of many low- and middle-income countries is evident. The annual cost of reduced labor productivity at country level already in 2030 can be several percent of GDP, which means billions of US dollars even for medium-size countries. The results provide new arguments for effective climate change adaptation and mitigation policies and preventive actions in all countries.

    2016-01-01

    Colonic angiodysplasia (AD) with bleeding as a comorbidity in the aging population is being increasingly reported. However, to our knowledge, there is no report on colonic AD accompanied by a huge hematoma. Herein, we report a case of colonic AD with a huge submucosal hematoma. A 75-year-old man with sudden melena was referred to our hospital. Helical computed tomographic angiography (CTA) revealed bleeding from the sigmoid colon. Additionally, colonoscopy showed a huge submucosal hematoma with bleeding in the sigmoid colon. As endoscopic hemostasis was difficult, sigmoidectomy was performed. The pathological diagnosis was colonic AD. The present case indicates that colonic AD should be considered in the differential diagnosis for melena. In addition, the case shows that helical CTA, which is a noninvasive imaging modality, is useful for the diagnosis of colonic AD and is as effective as colonoscopy and angiography for diagnosis.

    Teratomas are tumors composed of tissues derived from more than one germ cell line. They manifested with a great variety of clinical and radiological features. We report a case of a giant left hemithorax teratoma in a female with huge spleen tumor and review the relevant literature. A 38-year-old female with progressively aggravating dyspnea at rest from a mild trauma. Absent breath sounds on the left side. There was splenomegaly. Computed tomography scan revealed a huge mass (20 × 15 × 18 cm), containing elements of heterogeneous density in the left hemithorax. The spleen tumor was occupying most of the spleen without any other abdominal manifestations. The patient underwent left thoracotomy and laparoscopic splenectomy. Histopathological examination revealed a benign mature teratoma and cystic lymphangiomatosis of the spleen. To the best of our knowledge and after reviewing the available literature this is the first case of huge mature pulmonary teratoma with large cystic spleen lymphangiomatosis.

    A 30-year-old female was referred to our hospital for further examination of liver dysfunction. A huge, soft mass was noted in her left upper quadrant on physical examination. Abdominal ultrasonography and computed tomography revealed a huge cystic tumor of 20 cm in the hilus of the spleen. Serum CA19-9 was 491 U/ml, and splenectomy was performed under suspicion of a malignant cystic tumor. The inner surface of the cyst was lined by squamous epithelial cells that were immunohistochemically positive for CA19-9. Serum CA19-9 level was normalized after the surgery. Our case of a very rare, huge epidermoid cyst of the spleen suggests that measurement of the serum CA19-9 level is useful for evaluating therapeutic efficacy of a splenic epidermoid cyst.

    Hepatic artery aneurysms are rare but potentially life threatening. We describe a novel case of a successful endovascular coil embolization of a huge hepatic artery aneurysm. A 67-year-old woman presented with recent abdominal pain that had begun from 2 weeks before referring to our hospital. Sonographic and computerized tomographic (CT) findings revealed a huge hepatic artery aneurysm with 95 mm × 83 mm diameter. The patient underwent an endovascular technique. In aortic angiography, the celiac artery orifice and superior mesenteric artery were so narrow, so sonography was used in order to determine the exact position of the catheter in the celiac artery orifice. The aneurysm was thrombosed using coil embolization. Pulsation of the aneurysm immediately disappeared. Huge hepatic artery aneurysm can be safely treated using coil embolization.

    An intrathoracic meningocele is a relatively rare disease, and it commonly accompanies neurofibromatosis type 1. Patients tend to have no symptom but if its size is too large and compresses a lung and neighboring organs, it needs shunt drainage or surgical resection. Herein, we present the case of a 52 year-old female patient with huge intrathoracic meningoceles associated with neurofibromatosis type 1, who has complained about chest discomfort and dyspnea at rest. As for a preliminary treatment, a neurosurgeon had performed a cystoperitoneal shunt, but the symptoms continued and the size of mass and the amount of pleural effusion did not change significantly. Therefore, the huge thoracic meningoceles were successfully treated through the thoracotomic approach in combination with lumbar puncture and cerebrospinal fluid drainage. It is reported that double huge intrathoracic meningoceles associated with neurofibromatosis type 1 was successfully treated by a shunting procedure followed by thoracotomic resection with collaboration of a neurosurgeon.

    Paraovarian cysts are uncommon adnexal masses which are usually asymptomatic. We describe a case of bilateral huge paramesonephric cysts in a nulliparous woman. A 25-year-old lady presented with abdominal distension for one year duration. Examination and imaging revealed large abdominopelvic cystic masses with no solid areas or septations. Intraoperatively there were huge bilateral paraovarian cysts which were excised. Histopathology revealed low cuboidal to ciliated columnar epithelium with no evidence of ovarian parenchyma suggestive of paramesonephric cyst. Paraovarian cyst should be included in the differential diagnosis of a cystic mass visualised on ultrasound. PMID:24392412

    2015-07-01

    We report a unique case of chronic dissection of the ascending aorta complicated with huge and thrombotic pseudoaneurysm in a patient with coarctation of descending aorta. Preoperative investigations such as transesophageal echocardiography (TEE) confirmed the diagnosis of dissection. Intraoperative findings included a12 cm eccentric bulge of the right lateral side of dilated the ascending aorta filled with the clot and a circular shaped intimal tear communicating with an extended hematoma and dissection of the media layer. The rarity of the report is an association of the chronic dissection with huge pseudoaneurysm and coarctation. The patient underwent staged repair of an aneurysm and coarctation and had an uneventful postoperative recovery period.

    Full Text Available O objetivo do presente estudo foi a determinação das perdas físicas e econômicas de banana em diferentes equipamentos varejistas na Cidade de Botucatu - SP e suas possíveis causas. Os equipamentos foram sorteados aleatoriamente. As informações foram coletadas através da aplicação de questionário para a determinação das perdas de três variedades de banana. O resultado mostrou perda global de 39 toneladas, correspondente a 11,1% da quantidade comercializada, sendo 10,5% em supermercados, 15,0% em quitandas/sacolões e 10,6% em feiras livres. O valor total das perdas anuais atingiu R$ 35.038,00, em valores de maio de 2002. A manipulação excessiva do cliente, excedente de oferta, uso de embalagem inadequada e baixa qualidade da fruta foram as principais causas de perdas. Conclui-se pela necessidade de conscientização do cliente, do uso de embalagens plásticas e de cuidados no manuseio da fruta durante toda pós-colheita.The objective of this research was to determinate the physics and economic banana's loss and its possible reason, in several retail trades in the city of Botucatu - SP. The equipments were drawn aleatory. The information were collected through questions applied to people to determine the annual loss of three different varieties of banana. The results showed that all loss was 39 ton., that represents 11,1% of all saled in retail trades, with 10,5% in supermarkets, 15% in grocery store/retail shops, and 10,6% in free markets. The retail trade showed an annual loss of R$ R$ 35.038,00, in values of may/2002. The excessive handling by the client, excess offering inadequate packing, and low quality of fruit were the most important cause of losses. It was possible to conclude that, the client's behavior should be better, the plastic packing utilization, and caution in the handling during all the post harvest process.

    Siracusa, an important city of the south-east Sicily, is located in an area highly exposed to the danger of tsunami, local and remote. Among the many events that affected this area those with a major effect are the AD 365 tsunami generated by an earthquake in the Western Hellenic Arc, the event of 11 January 1693, following an earthquake in the area of Augusta, and the tsunami of 28 December 1908 generated in the Messina strait. The aim of this study is to evaluate the number of exposed people and of fatalities as well as the type of damage to constructions and the associated loss of economic value in case of a tsunami, based on a simple tsunami scenario, i.e. on assuming a uniform inundation level of 5 m. This figure is considered appropriate for this preliminary tsunami loss analysis since it is compatible with historical tsunami observations and is also supported by recent tsunami hazard studies carried out for this area (Armigliato et al., 2015). The main physical tsunami parameter used in computations is the water column, which is merely the difference between the assumed inundation level and the topographic altitude. We use numerical geo-referenced 1:2000 maps providing a database of constructions in the area of Siracusa together with data from national and local statistical institutions to make estimates on the number and type of buildings and on the number of people that may be found in the inundation area in different periods of the year, discriminating between residents and tourists. Using a variant of the Terrier et al. (2012) table and tsunami mortality curves proposed by Koshimura et al. (2009) we are able to estimate expected fatalities with tsunami inundation reaching at most the first floor of buildings. We calculate economic loss by taking into account both residential buildings and commercial-industrial structures and data from the real estate market. This study is funded by the EU Project ASTARTE - "Assessment, STrategy And Risk Reduction for

    In the article there are reported the methodological approaches to the calculation of actual and avoided as a result of control and supervisory activities of economic losses caused by mortality, morbidity and disability in the population, associated with the negative impact of environmental factors. There is suggested a consistent solution of the chain of problems: the establishment of cause-and-effect relationships between indices of the health status and indices of the quality of the environment; indices of the quality of the environment and indices of the control and supervision activity of organs and institutions of Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing calculation of the cases of violations of health prevented as a result of the activity ofthe service; evaluation of their economic equivalents. Approbation of approaches on the example of the Russian Federation allowed to establish that as a result of the activity of organs and institutions of Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing in 2013, a positive trend was observed on 51 indices of quality of the habitat environment, there were prevented about 160 thousands of deaths and more than 2 million cases of disease that would be held in conditions of the lack of adequate control and surveillance measures in the field of sanitary and epidemiological welfare of the population. Loss prevention of gross domestic product (GDP) amounted to more than 120 billion rubles, Tax shortfalls in the federal budget--about 25.7 billion rubles. With taking into account the costs of the federal budgetfor the activities of the Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing in 2013 in part to ensure sanitary epidemiological surveillance in the amount of 11.386 billion rubles there was prevented loss of GDP of 10.56 rubles per 1 rub. of the cost of the federal budget and there was warned the shortfall of taxes to

  20. Handbook on loss reserving

    Schmidt, Klaus; Schnaus, Anja

    2016-01-01

    This handbook presents the basic aspects of actuarial loss reserving. Besides the traditional methods, it also includes a description of more recent ones and a discussion of certain problems occurring in actuarial practice, like inflation, scarce data, large claims, slow loss development, the use of market statistics, the need for simulation techniques and the task of calculating best estimates and ranges of future losses. In property and casualty insurance the provisions for payment obligations from losses that have occurred but have not yet been settled usually constitute the largest item on the liabilities side of an insurer's balance sheet. For this reason, the determination and evaluation of these loss reserves is of considerable economic importance for every property and casualty insurer. Actuarial students, academics as well as practicing actuaries will benefit from this overview of the most important actuarial methods of loss reserving by developing an understanding of the underlying stochastic models...

  4. Constructing Optimal Coarse-Grained Sites of Huge Biomolecules by Fluctuation Maximization.

    Coarse-grained (CG) models are valuable tools for the study of functions of large biomolecules on large length and time scales. The definition of CG representations for huge biomolecules is always a formidable challenge. In this work, we propose a new method called fluctuation maximization coarse-graining (FM-CG) to construct the CG sites of biomolecules. The defined residual in FM-CG converges to a maximal value as the number of CG sites increases, allowing an optimal CG model to be rigorously defined on the basis of the maximum. More importantly, we developed a robust algorithm called stepwise local iterative optimization (SLIO) to accelerate the process of coarse-graining large biomolecules. By means of the efficient SLIO algorithm, the computational cost of coarse-graining large biomolecules is reduced to within the time scale of seconds, which is far lower than that of conventional simulated annealing. The coarse-graining of two huge systems, chaperonin GroEL and lengsin, indicates that our new methods can coarse-grain huge biomolecular systems with up to 10,000 residues within the time scale of minutes. The further parametrization of CG sites derived from FM-CG allows us to construct the corresponding CG models for studies of the functions of huge biomolecular systems.

    The patients with huge (≥10cm) or multiple hepatocellular carcinoma (HCC) in the right liver and insufficient size of the remnant left liver can not be performed an operation of right hemihepatectomy because of that liver failure will occur post operation. We designed anatomic trisegmentectomy in right liver to increase the ratio of future liver remnant volume (%FLRV), thus increasing resectability of huge or multiple HCC. Thirteen patients were analyzed by preoperative CT scan for liver and tumor volumetries. If the right hemihepatectomy was done, %FLRV would be at the range of 29.6%-37.5%. However, if trisegmentectomy was done, %FLRV would increase by an average of 14.0%. So patients will not undergo postoperative liver failure due to sufficient %FLRV. Therefore, we designed anatomic trisegmentectomy, with retention of segment 5 or segment 8, to increase %FLRV and increase the resectability for huge or multiple HCC. After trisegmentectomy, the inflow and outflow of remnant liver were maintained well. Severe complications and mortality were not happened post operation. Of the 13 patients, 10 survived up to now. Of the 10 living cases, postoperative lung metastasis was found in 2 and intrahepatic recurrence was found in 1. These 3 patients survive with tumor after comprehensive therapies including oral administration of Sorafenib. Compared to right hemihepatectomy, anatomic trisegmentectomy in right liver guarantees the maximum preservation of %FLRV to increase the resectability of huge or multiple HCC, thus improving the overall resection rate.

    Huge hepatocellular carcinoma (HCC) possesses a potential risk for spontaneous rupture, which leads to a life-threatening complication with a high mortality rate. In addition, a large HCC is frequently accompanied by intrahepatic metastases. We describe, the case of a 74-year-old woman with a huge extrahepatically expanding HCC with multiple intrahepatic metastases who was treated by liver resection with repeated transcatheter arterial chemoembolization (TACE). To prevent tumor rupture or bleeding, we performed right hepatectomy. After the operation, TACE was applied for multiple intrahepatic metastases in the remnant liver. Furthermore, the elevated protein induced vitamin K absence (PIVKA II) level had decreased to limits within the normal range. Three months after the first TACE, computed tomography revealed several recurrences in the liver. TACE was applied for the second and third time and the tumors were well controlled. Although, liver resection is occasionally performed for patients with huge HCC to avoid spontaneous tumor rupture, only surgical approach might not be sufficient for such advanced HCC. To achieve long-term survival, it is necessary to control the residual intrahepatic tumors. We could control multiple intrahepatic metastases with repeated TACEs after hepatectomy. Multimodal treatment involving hepatectomy and TACE might be a good treatment strategy for patients with huge HCC with multiple intrahepatic metastases if the tumors are localized in the liver without distant or peritoneal metastasis.

    The optimal treatment for huge unresectable hepatocellular carcinoma (HCC) remains controversial. The outcome of transcatheter arterial chemoembolization (TACE) for patients huge unresectable HCC is generally poor and the survival benefit of TACE in these patients is unclear. The aim of the study is to compare the effect of hepatic arterial infusion chemotherapy (HAIC) versus symptomatic treatment in patients with huge unresectable HCC. Since 2000 to 2005, patients with huge (size >8 cm) unresectable HCC were enrolled. Fifty-eight patients received HAIC and 44 patients received symptomatic treatment. In the HAIC group, each patient received 2.4+1.4 (range: 1-6) courses of HAIC. Baseline characteristics and survival were compared between the HAIC and symptomatic treatment groups. The HAIC group and the symptomatic treatment group were similar in baseline characteristics and tumor stages. The overall survival rates at one and two years were 29% and 14% in the HAIC group and 7% and 5% in the symptomatic treatment group, respectively. The patients in the HAIC group had significantly better overall survival than the symptomatic treatment group (Phuge unresectable HCC.

    BACKGROUND Kasabach-Merritt syndrome is a potentially fatal disease that consists of hemangioma(s) with thrombocytopenia, microangiopathic hemolytic anemia, and coagulopathy. Extensive hemangiomatosis is rare. We present the radiological features and treatment strategy of a young adult suffering from Kasabach-Merritt syndrome with widespread hemangiomas and an infected huge hematoma in the right thigh. CASE REPORT A 33-year-old Taiwanese male presented with a painful 20-cm mass over his right thigh and gross hematuria for 2 days. Hemangiomatosis was bioptically proven in infancy and the patient was under regular follow-up. Physical examination revealed normal heart rate, respiratory rate, and body temperature. Multiple palpable lumps with brown and purple areas of skin over the neck, trunk, and right thigh were noted. Laboratory examinations revealed thrombocytopenia anemia and elevated fibrin degradation products. There were no signs of sepsis. Blood transfusion and steroid therapy were executed. Computed tomography showed a huge complicated subcutaneous hematoma in the right thigh. Drainage of the huge hematoma was performed and antibiotics were prescribed. After the local infection in the right thigh and the bleeding tendency were controlled, the patient was discharged in a stable condition two weeks later. CONCLUSIONS A huge infected hematoma and widespread hemangiomas are extremely rare complications of Kasabach-Merritt syndrome. There are no known treatment guidelines currently available. Our patient was successfully treated with steroids, drainage, and antibiotics.

    Most hepatic cysts are asymptomatic, but complications occasionally occur. We describe a patient with biliary obstruction due to a huge simple hepatic cyst treated with laparoscopic resection. A 60-year-old Japanese woman was admitted to our hospital because of a nontender mass in the right upper quadrant of the abdomen. Laboratory tests revealed the following: serum total bilirubin, 0.6 mg/dL; serum aspartate aminotransferase, 100 IU/L; serum alanine aminotransferase, 78 IU/L; serum alkaline phosphatase, 521 IU/L; and serum gamma glutamic transpeptidase, 298 IU/L. Abdominal computed tomography, ultrasonography, and magnetic resonance cholangiopancreatography revealed a huge hepatic cyst, 13 cm in diameter, at the hepatic hilum, accompanied by dilatation of the intrahepatic bile duct and obstruction of the common bile duct. We diagnosed biliary obstruction due to a huge hepatic cyst at the hepatic hilum, and laparoscopic surgery was performed. A huge hepatic cyst was seen at the hepatic hilum. After needle puncture of the huge cyst, the anterior wall of the cyst was unroofed, and cholecystectomy was done. Intraoperative cholangiography through a cystic duct revealed stenosis of the duct. Subsequent decapsulation of the cyst was performed in front of the common bile duct. After this procedure, cholangiography revealed that the stenosis of the common bile duct had resolved. Histopathological examination of the surgical specimen confirmed the hepatic cyst was benign. The postoperative course was uneventful, and the results of liver function tests normalized. The patient was discharged 7 days after operation. Computed tomography 3 months after operation revealed disappearance of the hepatic cyst and no dilatation of the intrahepatic bile duct.

    Full Text Available A novel system of image retrieval, based on Hadoop and Spark, is presented. Managing and extracting information from Big Data is a challenging and fundamental task. For these reasons, the system is scalable and it is designed to be able to manage small collections of images as well as huge collections of images. Hadoop and Spark are based on the MapReduce framework, but they have different characteristics. The proposed system is designed to take advantage of these two technologies. The performances of the proposed system are evaluated and analysed in terms of computational cost in order to understand in which context it could be successfully used. The experimental results show that the proposed system is efficient for both small and huge collections.

    2014-01-01

    Full Text Available Invoice printing just has two-color printing, so invoice font image can be seen as binary image. To embed watermarks into invoice image, the pixels need to be flipped. The more huge the watermark is, the more the pixels need to be flipped. We proposed a new pixels flipping method in invoice image for huge watermarking capacity. The pixels flipping method includes one novel interpolation method for binary image, one flippable pixels evaluation mechanism, and one denoising method based on gravity center and chaos degree. The proposed interpolation method ensures that the invoice image keeps features well after scaling. The flippable pixels evaluation mechanism ensures that the pixels keep better connectivity and smoothness and the pattern has highest structural similarity after flipping. The proposed denoising method makes invoice font image smoother and fiter for human vision. Experiments show that the proposed flipping method not only keeps the invoice font structure well but also improves watermarking capacity.

    Conclusion: Ovarian cysts in young women who are associated with elevated levels of tumor markers and ascites require careful evaluation. Management of ovarian cysts depends on patient's age, size of the cyst, and its histopathological nature. Conservative surgery such as ovarian cystectomy or salpingo-oophorectomy is adequate in mucinous tumors of ovary. Multiple frozen sections are very important to know the malignant variation of this tumor and helps accurate patient management. Surgical expertise is required to prevent complications in huge tumors has distorted the anatomy, so gynecologic oncologist plays a prominent role in management. In this case, beside of the huge tumor and massive ascites uterine and ovaries were preserved by gynecologist oncologist and patient is well up to now.

    Congenital cervical teratomas are rare and usually large enough to cause respiratory distress in the neonatal period. We present two cases of congenital huge cystic neck masses in which distinguishing cervical cystic hygroma and congenital cystic teratoma was not possible through radiologic imaging techniques. Experience with the first case, which was initially diagnosed and treated as cystic hygroma by injection sclerotherapy, led to early suspicion and surgery in the second case. The masses were excised completely and histopathologic diagnoses were congenital teratoma in both patients. Our aim is to review congenital huge neck masses causing respiratory distress in early neonatal life to highlight this dilemma briefly with these interesting cases. Copyright © 2014.

    Echinococcocal cysts are predominantly located in the right liver. They are usually solitary and asymptomatic, but large cysts can cause compression symptoms. We report two cases of huge (25cm and 20cm in diameter, respectively) echinococcal cysts located in the left liver, which presented as a large palpable mass causing compression symptoms. Diagnosis was established with CT scan showing a cystic mass with the characteristic daughter cysts and reactive layer (pericystic wall) consisting of fibrous connective tissue and calcifications. Both patients were treated radically with left hepatectomy and had uneventful postoperative course and no recurrence upon follow-up. The treatment of liver echinococcal cysts represent a unique surgical challenge. Even though conservative approaches are less technically demanding, the radical approach with resection has better outcome with less recurrences, when performed by experienced surgeons. Resection rather than drainage is the management of choice for such huge liver echinococcal cysts. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

    2015-01-01

    We describe an R package named huge which provides easy-to-use functions for estimating high dimensional undirected graphs from data. This package implements recent results in the literature, including Friedman et al. (2007), Liu et al. (2009, 2012) and Liu et al. (2010). Compared with the existing graph estimation package glasso, the huge package provides extra features: (1) instead of using Fortan, it is written in C, which makes the code more portable and easier to modify; (2) besides fitting Gaussian graphical models, it also provides functions for fitting high dimensional semiparametric Gaussian copula models; (3) more functions like data-dependent model selection, data generation and graph visualization; (4) a minor convergence problem of the graphical lasso algorithm is corrected; (5) the package allows the user to apply both lossless and lossy screening rules to scale up large-scale problems, making a tradeoff between computational and statistical efficiency.

    2015-09-01

    We describe a case of mitral valve annular dilatation caused by a huge left atrial myxoma obstructing the mitral valve orifice. A 50-year-old man presenting with palpitation was found to have a huge left atrial myxoma protruding into the left ventricle during diastole, causing severe mitral regurgitation. The diagnosis was made with echocardiogram. Transoesophageal echocardiography revealed a solid mass of 75 × 55 mm. During operation, the myxoma was completely removed from its attachment in the atrium. We preferred to place a mechanical heart valve after an annuloplasty ring because of severely dilated mitral annulus and chordae elongation. The patient had an uneventful recovery. Our case suggests that immediate surgery, careful evaluation of mitral valve annulus preoperatively is recommended.

    We report a case of a huge gastric gastrointestinal stromal tumor(GIST)that was safely resected followingpreoperative imatinib therapy. A 72-year-old woman was hospitalized with severe abdominal distension. Computed tomography revealed a 27×17 cm tumor in the left upper abdominal cavity. The patient was diagnosed with high risk GIST by EUS-FNA. We initiated preoperative adjuvant chemotherapy with imatinib to achieve a reduction of operative risks and functional preservation. After 6 months of chemotherapy, CT showed a reduction in the tumor size and the patient underwent partial gastrectomy and partial resection of the diaphragm. Histologically, most of the tumor cells were replaced by hyalinized collagen and viable cells were scattered only around the blood vessels. Neoadjuvant chemotherapy with imatinib has the potential to become an important therapeutic option for the treatment of huge GISTs.

    The presence of primary intracardiac tumors are scarce, and most of them are myxomas. We reported, in this paper, a case with huge mass in the right side of the heart. A 45-year-old man, with a complaint of bilateral lower limbs edema and exertional dyspnea, was admitted to intensive cardiac care unit. Cardiac auscultation revealed soft grade systolic murmur without any evidence of "tumor plop." Echocardiography showed a huge mobile mass in right side of the heart that suggested myxoma. Our patient underwent cardiac surgery with excision of 13 cm mass. Histopathological study was confirmed the diagnosis of mass type. In this case report, it shows that in the differential diagnosis of right-sided heart failure, the right sided myxoma must be considered. The preferable approach in patient with cardiac myxomas is surgical excision to alleviate symptoms, early identification, and removal.

    Full Text Available We report a unique case of chronic dissection of the ascending aorta complicated with huge and thrombotic pseudoaneurysm in a patient with coarctation of descending aorta. Preoperative investigations such as transesophageal echocardiography (TEE confirmed the diagnosis of dissection. Intraoperative findings included a12 cm eccentric bulge of the right lateral side of dilated the ascending aorta filled with the clot and a circular shaped intimal tear communicating with an extended hematoma and dissection of the media layer. The rarity of the report is an association of the chronic dissection with huge pseudoaneurysm and coarctation. The patient underwent staged repair of an aneurysm and coarctation and had an uneventful postoperative recovery period.

    Invoice printing just has two-color printing, so invoice font image can be seen as binary image. To embed watermarks into invoice image, the pixels need to be flipped. The more huge the watermark is, the more the pixels need to be flipped. We proposed a new pixels flipping method in invoice image for huge watermarking capacity. The pixels flipping method includes one novel interpolation method for binary image, one flippable pixels evaluation mechanism, and one denoising method based on gravity center and chaos degree. The proposed interpolation method ensures that the invoice image keeps features well after scaling. The flippable pixels evaluation mechanism ensures that the pixels keep better connectivity and smoothness and the pattern has highest structural similarity after flipping. The proposed denoising method makes invoice font image smoother and fiter for human vision. Experiments show that the proposed flipping method not only keeps the invoice font structure well but also improves watermarking capacity.

    Huge (≥10 cm) hepatocellular carcinomas (HCCs) show dismal prognosis and only a limited number of cases are eligible for curative resection. We studied the therapeutic benefit of radiotherapy (RT) in patients with huge unresectable HCCs. Data from 283 patients with huge HCCs and preserved liver function who underwent non-surgical treatment from July 2001 to March 2012 were retrospectively reviewed. Patients were divided into 4 groups according to the initial treatment: Group A (N= 49), transarterial chemoembolization (TACE); Group B (N = 35), TACE + RT; Group C (N = 50), hepatic arterial infusion chemotherapy; and Group D (n = 149), concurrent chemoradiotherapy (CCRT). The median follow-up period was 27.8 months (range, 12.9-121.9 months). The median overall survival (OS) was longer in Groups B (15.3 months) and D (12.8 months) than in Groups A (7.5 months) and C (8.2 months; Group B vs. A, Bonferroni corrected P [P(c)] = 0.04; Group B vs. C, P(c) = 0.02; Group D vs. A, P(c) = 0.01; Group D vs. C, Pc = 0.006). Groups B and D also showed superior progression-free survival (PFS) and intrahepatic control than Groups A and C. In multivariate analysis, tumour multiplicity, serum alpha-foetoprotein level (≥200 ng/ml) and initial treatment were independent prognostic factors for OS and PFS. Patients with huge unresectable HCCs treated with RT, either as CCRT or in combination with TACE, showed excellent intrahepatic control and prolonged survival. RT could be considered a promising treatment modality in these patients. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    A 63-year old male was referred to our emergency unit due to acute renal failure. The level of serum renal function tests levels, blood urea nitrogen (BUN)/creatinine, were 63 mmol/L/848 μmol/L. CT (Computarised Tomography) scan showed a huge bladder stone (5 cm x 6 cm x 5 cm) with increased bladder wall thickness. Post-renal acute renal failure due to bilateral ureterohydronephrosis was diagnosed. The huge bladder stone was considered to be the cause of ureterohydronephrosis and renal failure. The patient was catheterised and received haemodialysis immediately. He received haemodialysis four times during ten days of hospitalization and the level of serum renal function tests levels (BUN/ creatinine) decreased 18 mmol/L/123 μmol/L. After improvement of renal function, we performed cystoscopy that demonstrated normal prostatic urethra and bladder neck and bilaterally normal ureteral orifices. Bladder wall was roughly trabeculated and Bladder outlet was completely obstructed by a huge bladder stone. After cystoscopy open, cystolithotomy was performed to remove calcium phosphate and magnesium ammonium phosphate stone weighing 200 g removed. Four days after operation the patient was discharged uneventfully and urethral catheter was removed on the seventh day. Post-renal acute renal failure due to large bladder stones is rare in literature. According to the our knowledge; early diagnosis of the stone avoid growth to large size and prevent renal failure.

    Summary Huge (≥10 cm) hepatocellular carcinoma (HCC) is not uncommon at clinical presentation, and the surgical outcomes of such tumors are poor. This systematic review aimed to assess the safety and efficacy of partial hepatectomy for huge HCC. We performed a search on Medline and PubMed databases for all relevant studies published prior to December 2009. After exclusions, 21 studies remained for appraisal and data extraction. All studies were classified as level-4 evidence. The median overall perioperative morbidity and mortality rates were 29.2% (range: 13.6–72%) and 3.5% (range: 0–18.2%), respectively. The overall median survival since the partial hepatectomy was 20.7 months (range: 10.1–32 months), with median 1-, 3- and 5-year survival of 60.7% (range: 41–72.2%), 34% (range: 0–60.3%) and 28.6% (range: 0–54%), respectively. The median disease-free survival since the partial hepatectomy was 11.3 months (range: 5.5–32months), with median 1-, 3- and 5-year disease-free survival rates of 48.7% (range: 32–65.4%), 27.5% (range: 14.1–49%) and 20.7% (range: 9.5–43%), respectively. Partial hepatectomy can be performed safely and is associated with long-term survival in a subset of patients with huge HCC, but the evidence of benefit is currently weak. PMID:21358616

    Focal nodular hyperplasia (FNH) is a benign lesion of the liver which is usually found in healthy adults, however, FNH is rare in children, and comprises only 2% of all pediatric liver tumors. Herein, we report the case of a 6-year-old child (male) with a huge FNH which size is more than 10cm. This could be the biggest FNH among all children's FNH cases ever reported. A 6-year-old boy was found a hepatic space-occupying lesion two years ago. As the time went by, the lesion became bigger gradually. The last CT examination showed the size of the tumor to be 10.5×9.9cm in the right hepatic lobe. This child underwent surgical resection of the tumor which was confirmed as FNH (11×8×7cm) by pathology. FNH is a benign lesion of the liver, and it is characterized by hepatocyte hyperplasia and a central stellate scar. It is uncommon for FNH to be diagnosed in children. Such huge FNH (about 11cm) is extremely rare. Surgical operation may be the effective method to cure huge FNH. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Bile duct injury is one of the known serious complications of laparoscopic fenestration for nonparasitic liver cysts. Herein, we report the case of a huge liver cyst for which we performed laparoscopic fenestration using intraoperative fluorescent cholangiography with indocyanine green. A 71-year-old woman with abdominal distention was referred to our hospital. CT demonstrated a 17 × 11.5-cm simple cyst replacing the right lobe of the liver, so laparoscopic fenestration was performed. Although the biliary duct could not be detected because of compression by the huge cyst, fluorescent cholangiography with indocyanine green through endoscopic naso-biliary drainage tube clearly delineated the intrahepatic bile duct in the remaining cystic wall. The patient had no complications at 3 months after surgery. Fluorescent cholangiography using indocyanine green is a safe and effective procedure to avoid bile duct injury during laparoscopic fenestration, especially in patients with a huge liver cyst. © 2015 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and Wiley Publishing Asia Pty Ltd.

    To compare the efficacy of hepatic resection (HR) and transarterial chemoembolization (TACE) for patients with solitary huge (≥ 10 cm) hepatocellular carcinoma (HCC). Records were retrospectively analyzed of 247 patients with solitary huge HCC, comprising 180 treated by HR and 67 by TACE. Long-term overall survival (OS) was compared between the two groups using the Kaplan-Meier method, and independent predictors of survival were identified by multivariate analysis. These analyses were performed using all patients in both groups and/or 61 pairs of propensity score-matched patients from the two groups. OS at 5 years was significantly higher in the HR group than the TACE group, across all patients (P = 0.002) and across propensity score-matched pairs (36.4% vs 18.2%, P = 0.039). The two groups showed similar postoperative mortality and morbidity. Multivariate analysis identified alpha-fetoprotein ≥ 400 ng/mL, presence of vascular invasion and TACE treatment as independent predictors of poor OS. Our findings suggest that HR can be safe and more effective than TACE for patients with solitary huge HCC.

    We describe a case of a huge intramural hematoma in a thrombosed middle cerebral artery aneurysm. A 47-year-old female patient with liver cirrhosis and thrombocytopenia presented to the neurosurgical unit with a 5-day history of headache and cognitive dysfunction. Magnetic resonance imaging and computed tomography of the brain showed a thrombosed aneurysm located in the right middle cerebral artery with a posteriorly located huge intramural hematoma mimicking an intracerebral hematoma. Imaging studies and cerebrospinal fluid analysis showed no evidence of subarachnoid hemorrhage. Angiography showed a partially thrombosed aneurysm at the origin of the right anterior temporal artery and an incidental aneurysm at the bifurcation of the right middle cerebral artery. Both aneurysms were embolized by coiling. After embolization, the thrombosed aneurysmal sac and intramural hematoma had decreased in size 4 days later and almost completely disappeared 8 months later. This is the first reported case of a nondissecting, nonfusiform aneurysm with a huge intramural hematoma, unlike that of a dissecting aneurysm.

    Cognitive economics is the economics of what is in people’s minds. It is a vibrant area of research (much of it within behavioural economics, labour economics and the economics of education) that brings into play novel types of data, especially novel types of survey data. Such data highlight the importance of heterogeneity across individuals and highlight thorny issues for welfare economics. A key theme of cognitive economics is finite cognition (often misleadingly called “bounded rationality”), which poses theoretical challenges that call for versatile approaches. Cognitive economics brings a rich toolbox to the task of understanding a complex world. PMID:28149186

    The Ranwu-Tongmai section of the Sichuan-Tibet Railway passes through the Palongzangbu River basin which locates in the southeast Qinghai-Tibetan Plateau. Due to widely distributed maritime glacier in this area, the huge glacier debris flows are very developed. Consequently, the disastrous glacier debris flows with huge scale (106-108 m3 for one debris flow event) and damage become one of the key influencing factors for the route alignment of the Sichuan-Tibet Railway. The research on disaster characteristics and mitigation measures of huge glacial debris flows in the study area were conducted by the remote sensing interpretation, field investigation, parameter calculation and numerical simulation. Firstly, the distribution of the glaciers, glacier lakes and glacier debris flows were identified and classified; and the disaster characteristics for the huge glacier debris flow were analyzed and summarized. Secondly, the dynamic parameters including the flood peak discharge, debris flow peak discharge, velocity, total volume of a single debris flow event were calculated. Based on the disaster characteristics and the spatial relation with the railway, some mitigation principles and measures were proposed. Finally, the Guxiang Gully, where a huge glacier debris flow with 2*108m3 in volume occurred in 1953, was selected as a typical case to analyze its disaster characteristics and mitigation measures. The interpretation results show that the glacier area is about 970 km2 which accounts for 19% of the total study area. 130 glacier lakes and 102 glacier debris flows were identified and classified. The Sichuan-Tibet Railway passes through 43 glacier debris flows in the study area. The specific disaster characteristics were analyzed and corresponding mitigation measures were proposed for the route selection of the railway. For the Guxiang Gully, a numerical simulation to simulate the deposition condition at the alluvial fan was conducted. the simulation results show that the

China is one of the countries seriously affected by marine disasters. In the marine disaster control, loss evaluation is the core content of disaster grade division and risk prevention of marine disasters, and is also the key to study the relationship between marine disasters and economic.Theoretically, the marine disaster will disrupt the normal order of production, reduce economic efficiency, and affect the marine economy. But from a dynamic point of view, investment and consumption caused by marine disasters may also make the marine disasters have posi-tive effects on the development of marine economy.Inaddition, the development of marine economy will in-crease the marine disaster losses. Therefore, the question that whether there is a correlation between the marine disaster losses and marine economic growth, is it positive or negative, is worth in-depth study. With the ocean development and exploitation in depth and breadth, marine disasters have become an important factor affecting the sustainable and healthy development of our marine economy.

    This study aims to evaluate the efficacy of five measures; including the release of two strains of Trichogramma, Bacillus thuringiensis (B.t.). Sweetened B.t. and the environmentally friend insecticide (Tracer®), to manage the grape moth, Lobesia botrana that infested the grape vines c.v. "Thompson seedless " in Egypt severely during the two successive years of 2011 and 2012. In concern to the release of the worldwide, Trichogramma evanescens Westwood., the mean total grape yield ranged from 8.00 to 14.00 ton/fed and from 6.90 to 11.9, in respect to the two seasons and the mean infestation percentages fluctuated between 50.00 and 16.14; 43.48 and 21.01 in sequence for the same years. The corresponding grape bunches loss percentages averaged from 21.43 to 6.91; 18.63 to 9.00,respectively for the same periods of this study. Whereas, it was noticed that in releasing the indigenous T. bourarchae was more effective than T. evanescens in reducing all the above mentioned grape yield particularly. Applying Bacillus thuringiensis (B.t.) and/or adding sugar as a stimulant to improve yields reduced the infestation and the crop loss percentage. However, Bacillus thuringiensis mixed with sugar which overweighed the use of Bacillus thuringiensis alone. Although Tracer® provided good harvest in both years, but unfortunately it affected the grape berries components rather than the other treatments. Control plots indicated 48 and 50% infestation, with very low yield compared with the other five trials to manage the assigned insect pest. For the first time worldwide economics and profits were computed taking into account the whole market sale, the total control costs and the gross income to decide the most profitable treatment for the table grape growers under the Egyptian conditions. It was found that the mean (L.E.) profits/fed were arranged in a descending order as follows: 470.95, 513.28, 504.78, 500.82, 397.25 and 0.00 for Bacillus thuringiensis + sugar, Trichogramma

    Accumulating evidence suggests platelets play critical roles in tumor metastasis. Moreover, the role of platelets in metastasis is partially correlated with inflammation. However, evidence regarding the contribution of platelets to hepatocellular carcinoma (HCC) metastasis is lacking. This study investigated the association between platelets and metastatic risk in HCC. We used huge HCC (diameter over 10 cm), a tumor subgroup with a strong inflammatory background, as a model to evaluate the potential predictive role of platelets and platelet-related biomarkers for metastasis in HCC patients undergoing transarterial chemoembolization. A logistic regression model was used to analyze risk factors for metastasis. Patients with huge HCC (n = 178) were enrolled, and 24.7% (44/178) of patients had remote metastases after treatment. Univariate analyses showed high platelet counts (P = 0.012), pretreatment platelet-to-lymphocyte ratios (pre-PLR) of 100 or more (P = 0.018) and post-PLR of 100 or more (P = 0.013) were potential risk factors for metastasis. Furthermore, multivariate analyses showed high platelet counts (odds ratio, 2.18; 95% confidence interval, 1.074-4.443; P = 0.031) and platelet-related biomarkers were independent risk factors for HCC metastasis. Particularly, the risk of metastasis in patients with high post-PLR values was significantly greater than patients with low post-PLR values. For tumor response and survival, patients with high platelet counts had faster disease progression (P = 0.002) and worse survival (P huge HCC undergoing chemoembolization, which supply clinical verification of the association between high platelet counts and HCC metastasis. © 2016 The Japan Society of Hepatology.

    To evaluate the safety and efficacy of Cyberknife stereotactic body radiation therapy (SBRT) and its effect on survival in patients with unresectable huge hepatocellular carcinoma (HCC) unsuitable of other standard treatment option. Between 2009 and 2011, 22 patients with unresectable huge HCC (≧10 cm) were treated with SBRT. dose ranged from 26 Gy to 40 Gy in five fractions. Overall survival (OS) and disease-progression free survival (DPFS) were determined by Kaplan-Meier analysis. Tumor response and toxicities were also assessed. After a median follow-up of 11.5 month (range 2-46 months). The objective response rate was achieved in 86.3% (complete response (CR): 22.7% and partial response (PR): 63.6%). The 1-yr. local control rate was 55.56%. The 1-year OS was 50% and median survival was 11 months (range 2-46 months). In univariate analysis, Child-Pugh stage (p = 0.0056) and SBRT dose (p = 0.0017) were significant factors for survival. However, in multivariate analysis, SBRT dose (p = 0.0072) was the most significant factor, while Child-Pugh stage of borderline significance. (p = 0.0514). Acute toxicities were mild and well tolerated. This study showed that SBRT can be delivered safely to huge HCC and achieved a substantial tumor regression and survival. The results suggest this technique should be considered a salvage treatment. However, local and regional recurrence remain the major cause of failure. Further studies of combination of SBRT and other treatment modalities may be reasonable.

    Phyllodes tumor is an extremely rare tumor of the breast. It occurs in females in the third and fourth decades. The difficulty in distinguishing between phyllodes tumors and benign fibroadenoma may lead to misdiagnosis. Lymph node involvement is rarely described in phyllodes tumors; for this reason, sentinel node biopsy may be warranted. We present a case of a 33-year-old woman affected by huge tumor of the right breast with ulceration in the skin with a rapid tumor growth and with omolateral axillary metastasis.

    Mature ovarian cystic teratomas are common benign ovarian neoplasm derived from germ cells. With increasing availability of ultrasound services even in developing countries, the diagnosis of benign ovarian tumour is made earlier and the size of the ovarian tumour at diagnosis is relatively small. It is unusual to find an ovarian cystic teratoma larger than 10 cm. We report a huge mature ovarian cystic teratoma in a multipara with a history of Hansen's disease. We conclude that, in circumstances where women have restricted access to health care, the unusual finding of mature ovarian cystic teratoma larger than 10 cm is possible due to delayed presentation for diagnosis and treatment.

    Cemento-ossifying Fibroma (COF) is an osteogenic benign neoplasm affecting the jaws and other craniofacial bones. It commonly presents as a progressively slow growing pathology, which can sometimes attain an enormous size, causing facial deformity. A case of a huge cemento-ossifying fibroma, appearing as a mandibular dumbell tumour in a male patient is documented, which caused massive bone destruction and deformity. It was surgically removed by performing en bloc resection of mandible avoiding the splitting of lower lip incision technique, thereby maintaining his normal facial appearance.

    We report a young healthy woman, who believed that the consumption of large amounts of honeycomb would lead to good health and who finally developed a huge gastric bezoar of hard consistency. The conventional endoscopic techniques failed to manage the bezoar. Using the combination of injection of hydrogen peroxide 3% solution inside the bezoar to induce disintegration and a special designed needle-knife sphincterotome (bezotome) we managed to remove the bezoar in fragments. To the best of our knowledge this is the first reported bezoar caused by honeycomb. PMID:19829904

    We propose and analyze a superluminal ring laser gyroscope (RLG) using multilayer optical coatings with huge group delay (GD). This GD assisted superluminal RLG can measure the absolute rotation with a giant sensitivity-enhancement factor of ~10(3); while, the broadband FWHM of the enhancement factor can reach 20 MHz. This superluminal RLG is based on a traditional RLG with minimal re-engineering, and beneficial for miniaturization according to theoretical calculation. The idea of using GD coatings as a fast-light medium will shed lights on the design and application of fast-light sensors.

    Objectives Cotton is an important economic crop in China. Frequent outbreaks of biological disasters such as plant disease and pest insect has been threatening the cotton production in China since 1991. [Methods] In current study, by using 20 years’ statistical data of cotton protection, cotton yields and occurrence of pathogens and pest insects, we mainly analyzed the potential tendency of occurrence areas, yield enhance after control, actual loss yield after control of cotton pest insect and disease from 1991 to 2010. [Results] Firstly, with respect to the pest insect, the occurrence areas and control areas decreased 24.2% and 15.1% while yield enhance after control, actual loss yield after control increased 25.3% and 22.4%, respectively. With respect to the pathogen disease, the occurrence areas, control areas, yield enhance after control, actual loss yield after control all increased 16.2%, 38.3%, 303.8%and 175.4%, respectively. Secondly, the occurrence areas, control areas, yield enhance after control, actual loss yield after control from pest insect were higher than these from pathogen diseases. Thirdly, although we took a series of control measures, the actual loss yield rate caused by insect pest and pathogen disease were elevated from 4.0% in 1991 to 5.7% in 2010. Specifically, the actual loss yield caused by pest insect and pathogen disease was increased from 19.06 ton and 3.90 ton in 1991 to 23.33 ton and 10.72 ton in 2010, respectively. Finally, pathogen diseases and pest insects of cotton mainly occurred in Middle and Eastern regions as well as Xinjiang’s districts of China. [Conclusion] Pest insects and pathogen disease are still important factors influencing the cotton production in China. In order to effectively reduce the negative effect of cotton pest insect and pathogen disease, we should establish the risk assessment and monitor and warn those biological disasters in time, improve the ecological environment of farmland, increase the

    Surgery for massive abdominal tumors is both interesting and challenging. We present a case involving a multiple uterine myoma weighing 6.2 Kg which coincided with omental leiomyosarcoma. To our knowledge, this is the first report of this type of condition in the English literature. A 44-year-old nulliparous woman had suffered from abdominal pain for a long time. A huge abdominal mass was palpated on physical examination. Computed tomography scanning revealed a huge pelvic-abdominal mass with the possibility of small bowel loops invaded by the mass. A 6-cm omental mass was incidentally found during the subsequent hysterectomy procedure. Perforation of the urinary bladder occurred during the dissection of adhesion. Resection of the omental mass, wide wedge resection of the invaded small bowel, primary repair of the bladder, and hysterectomy were performed. The final pathologic diagnosis was uterine leiomyomata with omental leiomyosarcoma. The patient returned home on postoperative day 14 and was well at the 18-month follow-up examination. The challenge of these tumors lies in their proper diagnosis and surgical management. More case reports and follow-up studies are needed to confirm the efficacy of their management.

    Full Text Available The aim of this study is to examine the safety and efficacy of Cinobufacini injection in transarterial chemoembolization (TACE for treatment of huge hepatocellular carcinoma (HCC. Clinical data of 56 consecutive patients with HCC larger than 10 cm who had been treated with TACE between December 2010 and August 2014 were retrospectively analyzed. Among these patients, 31 belonged to the Cinobufacini group and 25 belonged to the epirubicin group. The clinical efficacy, survival time, and adverse events in patients in the two groups were compared. The objective response rate in the Cinobufacini group was significantly higher than that in the epirubicin group (53.6% versus 23.1%, P=0.022. The median survival time (10.6 versus 14.1 months, χ2=0.092, P=0.762 and the median time to progression (4.9 versus 5.7 months, χ2=0.097, P=0.756 were similar between the groups. The incidence rate of adverse events was lower in the Cinobufacini group than in the epirubicin group (P<0.05. The short-term clinical efficacy of Cinobufacini is better than that of epirubicin in TACE for treating huge HCC, while their long-term clinical efficacy is similar. However, lower incidence of adverse events was noted in TACE using Cinobufacini rather than epirubicin.

    Cemento-ossifying fibroma, also known as ossifying fibroma, usually occurs in the mandible and less commonly in the maxilla. The huge example in the skull base is even rare. We present a case of a huge cemento-ossifying fibroma arising below the skull base of a 30-year-old woman patient. Radiologic investigations showed a giant, lobulated, heterogeneous calcified hard tissue mass, which is well circumscribed and is a mixture of radiolucent and radiopaque, situated at the rear of the right maxilla to the middle skull base. The tumor expands into the right maxillary sinus and the orbital cavity, fusing with the right maxilla at the maxillary tuberosity and blocking the bilateral choanas, which caused marked proptosis and blurred vision. The tumor was resected successfully by intraoral approach, and pathologic examination confirmed the lesion to be a cemento-ossifying fibroma. This case demonstrates that cemento-ossifying fibroma in the maxilla, not like in the mandible, may appear more aggressive because the extensive growth is unimpeded by anatomic obstacles and that the intraoral approach can be used to excise the tumor in the skull base.

    'Qin brick and Han tile' has a great worldwide reputation in the architectural history of China. According to the former archaeological materials, the big hollow brick is usually one meter long and thirty to forty centimeters wide, while the solid brick is generally much smaller. But in 1995, large scale vestiges and structures were unearthed at the center of Guangzhou's old district, from the relic of Nanyue Kingdom Palace, which was built some 2000 years ago during the Western-Han Dynasty, A great number of earthen structural members were discovered, especially the solid glazed bricks in various beautiful patterns with an astonishing thickness and size. Some of them are one meter square, more than 20 centimeters thick, and weight half a ton, which are named ‘Brick No.1 in the world' by excavators. People have shown great interest in how to make these huge glazed bricks at the ancient technical conditions, because it is very difficult to manufacture such huge bricks even with the modern technology. At the request of Guangdong Nanyue Kingdom Palace Museum, Shanghai Institute of Ceramics carried out systematical measurements and analysis on these bricks and studied the physical and chemical forming mechanisms from their chemical compositions, structure, and physical characteristics. Here the technical characteristics of the bricks are also discussed.

    Spatial heterogeneity can have serious effects on the precision of field experimentation in plant breeding. In the present study the capacity of the honeycomb design (HD) to sample huge spatial heterogeneity was appraised. For this purpose, four trials were conducted each comprising a lentil landrace being screened for response to viruses. Huge spatial heterogeneity was reflected by the abnormally high values for coefficient of variation (CV) of single-plant yields, ranging 123-162 %. At a given field area, increasing the number of simulated entries was followed by declined effectiveness of the method, on account of the larger circular block implying greater intra-block heterogeneity; a hyperbolic increasing pattern of the top to bottom entry mean gap (TBG) indicated that a number of more than 100 replicates (number of plants per entry) is the crucial threshold to avoid significant deterioration of the sampling degree. Nevertheless, the honeycomb model kept dealing with variation better than the randomized complete block (RCB) pattern, thanks to the circular shape and standardized type of block that ensure the less possible extra heterogeneity with expanding the area of the block. Owing to the even and systematic entry allocation, breeders do not need to be concerned with the extra spatial heterogeneity that might induce the extra surface needed to expand the size of the block when many entries are considered. Instead, they could improve accuracy of comparisons with increasing the number of replicates (circular blocks) despite the concomitant greater overall spatial heterogeneity.

    Graph matching is essential in several fields that use structured information, such as biology, chemistry, social networks, knowledge management, document analysis and others. Except for special classes of graphs, graph matching has in the worst-case an exponential complexity; however, there are algorithms that show an acceptable execution time, as long as the graphs are not too large and not too dense. In this paper we introduce a novel subgraph isomorphism algorithm, VF3, particularly efficient in the challenging case of graphs with thousands of nodes and a high edge density. Its performance, both in terms of time and memory, has been assessed on a large dataset of 12700 random graphs with a size up to 10000 nodes, made publicly available. VF3 has been compared with four other state-of-the-art algorithms, and the huge experimentation required more than two years of processing time. The results confirm that VF3 definitely outperforms the other algorithms when the graphs become huge and dense, but also has a very good performance on smaller or sparser graphs.

    Prostate cancer is a growing public health problem. The palliation of pain in patients with painful bone metastases is of primary importance in the clinical management of advanced cancer. Internal therapy with radionuclides, which concentrate at sites of increased bone turnover, is used to control pain and improve quality of life as an alternative to conventional therapies. In the present study, we report the case of a 52-year-old male who had been diagnosed with prostate cancer. The patient presented with severe pain in multiple areas, but particularly in the right hip. A whole-body bone scan revealed that the right hip, ilium and ischium were covered with huge metastatic lesions. Treatment with radionuclide strontium-89 chloride ((89)Sr) resulted in a partial response which was confirmed by the successful relief of pain and other imaging modalities. No significant change in the leukocyte or thrombocyte levels was observed. The results of the present study indicate that systemic radionuclide therapy using (89)Sr is an effective, well-tolerated and safe palliative treatment in patients with huge osseous metastases in prostate carcinoma.

    Objective To investigate the possibility and surgical procedures for huge liver cancer involving the second porta hepatis.Methods 55 cases of huge liver cancer, with the diameter of 8-28 cm(mean 12.7 cm) were studied. Right subcostal or “rooftop” incision was made, the liver ligments were divided, good exposure of the tumor and access to retrohepatic inferior vena cava were achieved.Hepatectomies were completed under intermittent interruption of first porta hepatis. Occluding tape around vena cava was applied before liver resection if necessary.Results All tumors were successfully resected without death during operation.The longest survival time was now 4 years in one case. The 1-4 year postoperative survival rates were 63%,50%,50% and 30% respectively.Conclusion Young patients with solitary large liver tumor, which grows slowly over a long period on basis of non-cirrhotic or mild cirrhotic liver, should undergo an exploration in an attempt of resection irrespective of the image contraindication, provided that there is no extra-hepatic metastasis.

    A male of 17 years old complained of bilateral nasal congestion with mouth breathing for half a year. The physical examination showed patency of bilateral nasal cavity. Nasopharyngeal fiberscope revealed a huge spherical smooth reddish mass at the nasopharyngeal posterior wall and the back-end of nasal cavity blocking the entire postnaris and contacting with bilateral tubal tori, the size of which is about 3.5 cm x 2.5 cm. The nasopharyngeal 3D-CT showed a low density cystic mass area in the nasopharynx with smooth edges, and the CT value is approximately 32.4 HU. No exact enhancement was observed. The cystic mass originated from and compressed the back end of nasal septum. A semicircular defect in the leading edge of clivus was observed, and the inferior wall of sphenoid sinus is compressed uplifted upwards. The nasopharyngeal MR showed that the nasopharyngeal lesion presented short T1 and long T2 signals with multiple small wall nodules around. Neither the lesion nor the peripheral nodules can be significantly enhanced by enhancement scan. After a nasal endoscopic surgery, the case was definitely diagnosed as nasal septum back-end huge cyst.

It demonstrates that the economic liberalization is an absolute prerequisite for the transition to sustainable socio-economic development. Such development must rely on investment activities of the state, which in the current circumstances is a necessary but not sufficient measure for reversing the negative trends. The negative developments can be prevented only through implementation, along with the institutional changes in the economic area that form a strata of economically independent entrepreneurs-innovators, of no less profound transformation in political institutions aimed at democratization of public life

    Chronically reduced glomerular filtration rate (GFR) in old people does not always mean that they suffer from chronic kidney disease (CKD) since their GFR can just be reduced by aging. The HUGE equation has been recently described and validated in Spain for screening CKD without taking into account the patient's GFR value. This equation is based on patient's hematocrit, plasma urea levels and gender. The present study documented that the HUGE equation had and acceptable performance for screening CKD in elderly Argentine patients.

    Full Text Available Many experts interested in explaining and understanding the deepness of latest financial crisis, far away yet to be solved, have gone beyond the appearances capture only by the economic science. It is more than sure that bubble on US prime rate real estate market was a only the detonator of much more complex mechanism built in time behind the scene of the financial system. Two things are more perceivable, the lack of comprehensive, but not overburdened, regulations and the sophisticated financial products less understood even by the managers of the financial institutions using them. A question still remains. Who was actually in charge with the explosion and the changing nature of the derivatives products, as innovation in every field of human activity is not always to be blamed? When the crisis burst, we were talking about toxic financial products with a huge capability to contaminate the entire globe. When the things became a little calmer, we started to call them exotic financial products and now it is a vague feeling of forgetting about the bad impact they produced, focusing ourselves on the new and more needed regulation of the global financial system, leaving aside the human behavior. What we see is that financial world became huge as compared with the real economy and, as a long time and well experienced former banker said, huge money are looking for more huge yields, producing more money out of nothing. That simple thought brings us to the ethic in economics and morality in the financial system, completely reversed from the normality, if just have a look to the anti cycle movement between the bonus policy and the losses or failures of some banks in the latest years. The connection is to be found in the risky management of the risks in very exposed markets to the information asymmetry, moral hazard and herd behavior.

    There is limited information available regarding the treatment of huge hypertensive putaminal hemorrhage (HPH). This study aimed to evaluate our experience of 33 patients with huge HPH who were treated by open surgery (decompressive craniectomy and hematoma evacuation) and external cerebrospinal fluid (CSF) drainage. We reviewed the records of 33 consecutive patients admitted to our hospital with huge HPH (≥ 60 cm(3)). All patients were treated by decompressive craniectomy, hematoma evacuation, and CSF drainage. Data collected included age, gender, blood pressure at admission, Glasgow Coma Scale (GCS) score, intracranial hemorrhage (ICH) location, ICH volume, degree of midline shift, presence/absence of basal cistern obliteration at admission and before surgery, and presence/absence of intraventricular hemorrhage (IVH). Outcome was assessed by the Glasgow Outcome Scale score at 30 days after surgery. The median GCS score was 5.0 at admission, and improved to 8.0 at 1 week after surgery. The median ICH volume was 95 cm(3) before surgery and 4 cm(3) after surgery. IVH was observed in 93.9% of patients. The overall survival rate to discharge was 75.6% (25/33), including 15.1% (4/33) with good function, 36.4% (12/33) with disability, and 24.3% (8/33) in a vegetative state. The mortality rate was 24.3% (8/33). Patients with right-sided ICH had better outcomes than those with left-sided ICH. No patients with GCS score ≤ 6 and ICH volume ≥ 90cm(3) at admission achieved good postoperative function. Operative time was significantly shorter with hematoma evacuation via the transcortical approach than via the transsylvian approach (3.41 ± 0.75 h vs. 4.14 ± 0.59 h, Phuge HPH by decompressive craniectomy, hematoma evacuation, and CSF drainage is life-saving. Patients with GCS score 7-8, ICH volume 60-90 cm(3), and right-sided ICH may achieve good recovery. The transcortical approach appears to be more effective than the transsylvian approach for rapid decompression of

    2007-01-01

    The relative importance of economics and environment in debate may soon be reversed due to the influence of three factors. Firstly, in the global economy it is hard to hide the unwanted products of economic processes. Secondly, huge advances in science will reduce the imperfect knowledge of markets, making some monitoring and analyzing tools show the design of sensible and equitable livelihood in communities, which is more important than the motivation of maximising profits for some individuals or fums. Thirdly, China, as the last major player on the planet to take on economic growth, comes from traditions fundamentally different from those economies that have experienced the Industrial Revolution previously. Its challenges with sustainability and environmental conservation predate Western economics by millennia,and it is implementing policies domestically and starting to work on the world stage that acknowledges that the surroundings are the host for any economic and socio-political system.

    Full Text Available Parachordoma is an extremely rare soft tissue tumor of unknown lineage. Parachordoma develops most often on the extremities. Only 2 cases have been reported as pelvic parachordoma. A 46-year old Egyptian woman with a huge painful pelvic mass was found to have a parachordoma with ectopic pelvic right kidney. There is only one report in the literature of fine needle aspiration cytology in this setting. The microscopic picture of parachordoma is not new to pathologists but the gross picture of this rare tumor has not previously been published; not even in the World Health Organization classification of soft tissues tumors. Diagnosis was confirmed by immuno-histochemistry. The patient is in good clinical condition without any evidence of recurrence or metastasis after 84 months of follow up.

    Full Text Available Ni–Mn–Ga polycrystalline alloy fibers with diameters of 33 μm are reported to exhibit significantly improved ductility and huge superelastic and shape memory strains in comparison to conventional brittle bulk polycrystalline alloys. Particularly, the recoverable strain of the Ni54.9–Mn23.5–Ga21.6 fiber can be as high as 10% at 40 °C. Such optimized behavior has been achieved by a suitable fabrication process via a glass-coating melt spinning method. The superelastic properties at different temperatures and the shape memory effect of Ni54.9–Mn23.5–Ga21.6 fibers were investigated.

    Nanocrystals, despite their tiny sizes, contain thousands to millions of atoms. Here we show that the large number of atoms packed in each metallic nanocrystal can provide a huge gain in signal amplification for biomolecule detection. We have devised a highly sensitive, linear amplification scheme by integrating the dissolution of bound nanocrystals and metal-induced stoichiometric chromogenesis, and demonstrated that signal amplification is fully defined by the size and atom density of nanocrystals, which can be optimized through well-controlled nanocrystal synthesis. Further, the rich library of chromogenic reactions allows implementation of this scheme in various assay formats, as demonstrated by the iron oxide nanoparticle linked immunosorbent assay (ILISA) and blotting assay developed in this study. Our results indicate that, owing to the inherent simplicity, high sensitivity and repeatability, the nanocrystal based amplification scheme can significantly improve biomolecule quantification in both laboratory research and clinical diagnostics. This novel method adds a new dimension to current nanoparticle-based bioassays.

    We report on the case of a huge varix that developed after the endovascular embolization of a cerebellar arteriovenous malformation (AVM) with a single drainer. A 21-year-old male presented with trigeminal neuralgia which was caused by the dilated drainer of the AVM. A varix was found at the basal vein of Rosenthal 2 months after an initial stage of embolization with polyvinyl alcohol particles; it diminished after the surgical extirpation of the AVM. The varix formation might have been facilitated by the stenosis in the vein of Galen and by the dynamic changes that followed the embolization. This rare complication should be kept in mind when embolization is performed for AVMs with impaired venous outlets. (orig.).

    Huge spin-transfer torque (STT) in a magnetic tunnel junction (MTJ) achieved by superlattice barrier composed of alternate layers of a nonmagnetic metal and an insulator is proposed. The magnitude of the STT depends on the number of cells in the superlattice barrier and the nonmagnetic metal layer's thickness. The result shows that the STT of the novel superlattice-barrier MTJ can reach values up to four orders of magnitude greater than those of traditional single-barrier stacks based on three cells superlattice by designing the nonmagnetic metal layer's thickness. In addition, the spin-transfer torque of the proposed MTJ can also be thousands of magnitude greater than those of traditional double-barrier MTJs.

    Full Text Available Renal Angiomyolipoma (AML is an unusual benign mesenchymal tumor with no malignant potential. It is composed of adipose tissue, smooth muscle and abnormal thick walled blood vessels. It can occur sporadically or may be associated with tuberous sclerosis. Sporadic angiomyolipoma (AML coexisting with simple renal cyst is extremely rare and only one case report is available in the literature. In our case, unique combination of sporadic AML along with simple renal cyst with huge size and weight was noted. To the best of our knowledge, ours is the second such case and first case from India. Due to its large size, complete nephrectomy was performed to avoid chances of rupture and retroperitoneal hemorrhage. Post-operative period was uneventful and the patient ahs been on regular follow-up.

    Spontaneous rupture of the collecting system with extravasation of urine and urinoma formation is usually associated with urinary tract obstruction by a ureteral calculus. Tumor growth is an extremely rare cause of urinary extravasation. Here we report a case of bilateral obstructive uropathy with a huge spontaneous left retroperitoneal urinoma caused by advanced infiltrative transitional cell carcinoma of the urinary bladder. The point of leakage was located in the left renal pelvis. The urinary leakage ceased after percutaneous nephrostomy drainage, and the patient subsequently underwent radical cystoprostatectomy. Histopathology revealed a high-grade urothelial carcinoma of the urinary bladder with pelvic lymph node metastasis. The patient refused any adjuvant treatment and expired 6 months after the operation from disseminated metastasis from bladder cancer. Copyright © 2011. Published by Elsevier B.V.

    Full Text Available Personal recommendation system is one which gives better and preferential recommendation to the users to satisfy their personalized requirements such as practical applications like Webpage Preferences, Sport Videos preferences, Stock selection based on price, TV preferences, Hotel preferences, books, Mobile phones, CDs and various other products now use recommender systems. The existing Pearson Correlation Coefficient (PCC and item-based algorithm using PCC, are called as UPCC and IPCC respectively. These systems are mainly based on only the rating services and does not consider the user personal preferences, they simply just give the result based on the ratings. As the size of data increases it will give the recommendations based on the top rated services and it will miss out most of user preferences. These are main drawbacks in the existing system which will give same results to the users based on some evaluations and rankings or rating service, they will neglect the user preferences and necessities. To address this problem we propose a new approach called, Personnel Recommendation System (PRS for huge data analysis using Porter Stemmer to solve the above challenges. In the proposed system it provides a personalized service recommendation list to the users and recommends the most useful services to the users which will increase the accuracy and efficiency in searching better services. Particularly, a set of suggestions or keywords are provided to indicate user preferences and we used Collaborative Filtering and Porter Stemmer algorithm which gives a suitable recommendations to the users. In real, the broad experiments are conducted on the huge database which is available in real world, and outcome shows that our proposed personal recommender method extensively improves the precision and efficiency of service recommender system over the KASR method. In our approach mainly consider the user preferences so it will not miss out the any of the data

    Splenic cysts are rare in all age groups and there are a few reports in the world literature. Primary cysts occur most frequently in children and young adults, comprising around 25% of all nonparasitic splenic cysts. Various techniques are suggested for the treatment of splenic cysts. In this case report, a huge epithelial splenic cyst in a 17-year-old female is presented and different treatment methods of splenic cysts are evaluated. A 17-year-old female presented with progressive abdominal mass in left upper quadrant associated with abdominal pain and food intolerance of duration of several months. There was no history of trauma. On physical examination, there was a huge mass located in the upper left side of abdomen. Computerized tomography scan revealed that a large cystic lesion had occupied the spleen with dimensions of 32x21xI5.6 cm. After patient preparation laparotomy was performed and complete cyst excision was done with splenectomy, patient was discharged after 2 days. This is a report of a case of epithelial splenic cyst of the spleen in a 17-year old female. The management of splenic cysts continues to evolve and the optimum treatment of patients with nonparasitic splenic cysts is controversial, as a principle preservation technique of the spleen with minimally invasive methods such as laparoscopy is preferred to splenectomy with the exception of very large cysts and when splenic hilum is involved in cyst wall. However, significant cyst recurrences were encountered with these techniques. Recently open partial splenectomy has been proposed as a safe and effective method in the management of NPSCs it ensures complete cyst removal, lack of cyst recurrence, and preservation of the spleen functions.

    Oil pollution to aquatic devices, especially to those oil-cleaning devices and equipment-repairing robots during oil spill accidents, has drawn great attention and remains an urgent problem to be resolved. Developing devices that can move freely in an oil/water system without contamination from oil has both scientific and practical importance. In nature, the insect water strider can float on water by utilizing the superhydrophobic supporting force received by its legs. Inspired by this unique floating phenomenon, in this article, we designed a model device named "oil strider" that could float stably at the oil/water interface without contamination by oil. The floating capability of the oil strider originated from the huge underwater superoleophobic supporting force its "legs" received. We prepared the micro/nanohierarchical structured copper-oxide-coated copper wires, acting as the artificial legs of oil strider, by a simple base-corrosion process. The surface structures and hydrophilic chemical components of the coatings on copper wires induced the huge superoleophobic force at the oil/water interface, to support the oil strider from sinking into the oil. Experimental results and theoretical analysis demonstrate that this supporting force is mainly composed of three parts: the buoyancy force, the curvature force, and the deformation force. We anticipate that this artificial oil strider will provide a guide for the design of smart aquatic devices that can move freely in an oil/water system with excellent oil repellent capability, and be helpful in practical situations such as oil handling and oil spill cleanup.

  16. ECOLOGICAL ECONOMICS VS ECONOMIC(AL ECOLOGY

    2015-10-01

    Full Text Available Currently world faces the dilemma – ecological economy or economic(al ecology. The researchers produce hundreds of surveys on the topic. However the analyses of recent most cited simulations had shown the diversity of results. Thus, for some states the Kuznets environmental curve has place, for others – no. Same could be said about different years for the same state. It provokes the necessity of drawing new group analyses to reveal the tendencies and relationships between economic and environmental factors. Most flexible and mirror factor of environmental sustainability is the volume of CO2 emissions. The econometric analysis was used for detecting the economic impact on this indicator at the global level and in the spectra of group of states depending on their income. The hypothesis of the existence of environmental Kuznets curve for the analysed data is rejected. Real GDP per capita impact on carbon dioxide emissions is considered only at the global level. The impact of openness of the economy is weak. Rejection happened also to the hypothesis that for the developed countries there is a reverse dependence between the environmental pollution and economic openness. Indicator “energy consumption per capita” impacts on greenhouse gas emissions only in countries with high income. Whereby it should be noted that the more developed a country is, the more elastic is this influence. These results have a potential usage for environmental policy regulation and climate strategy.

    This paper briefly reviews the economic performance of China's economic reform starting in 1978, and which it presents personal views on the experiences of Korea's economic development and lessons for China's economic reform. The paper reviews the ChinaKorea economic relationship, and explores both the opportunities of China's economic development for Korea and the prospects for Bilateral Economic cooperation. It is estimated that the Chinese economy will maintain dynamic growth for the coming decade. The 2008 Olympic Games and the 2010 World Expo in China will provide further impetuses for Chinese economic development. China's huge market and its rapid economic growth can help the further recovery and development of the Korean economy. At the same time, the further development of the Chinese economy can benefit from financial, technical and managerial support from Korea. The complementarities between the industrial structures of China and Korea will surely push their future economic cooperation into a broader and deeper stage. Bilateral trade will enhance the competitiveness of both nations in the global market and help them achieve mutual prosperity and development.

    Inflammation is particularly strong in huge hepatocellular carcinoma (HCC). However, it is unclear whether the platelet-to-lymphocyte ratio (PLR), as an inflammatory-related marker, can predict survival of patients with huge HCC. In this study, we enrolled 291 patients with huge HCC (diameter over 10 cm) who were undergoing repeated transarterial chemoembolization (TACE) at our institute. The baseline PLR was calculated from complete serum blood counts before the first chemoembolization. We found that a baseline PLR cutoff value over 150 best predicted huge HCC survival. The 12, 24, and 36 months survival rates in the high PLR group (22.6, 8.1, and 4.1 %, respectively) were significantly lower than in the low PLR group (35.6, 22.4, and 14 %, respectively). Thus, a significant difference was found in overall survival (log-rank test, p huge HCC, a high baseline PLR is a useful predictor of poor survival in patients undergoing chemoembolization. Additional anti-inflammatory or anti-platelet treatments, in combination with TACE, may improve survival in HCC patients with high PLR.

    Despite increasing use in clinical practice, an estimated glomerular filtration rate value (eGFR) of HUGE formula. A formula including haematocrit , blood urea, and gender (HUGE), diagnoses CRI regardless of the variables of age, blood creatinine, creatinine clearance, or other eGFR. The HUGE formula is: L = 2.505458 - (0.264418 x Hematocrit) + (0.118100 x Urea) [+ 1.383960 if male]. If L is a negative number the individual does not have CRI; if L is a positive number, CRI is present. Our data demonstrate that the HUGE formula is more reliable than MDRD and CKD-EPI, particularly in persons aged over 70. Our HUGE screening formula offers a straightforward, easily available and inexpensive method for differentiating between CRI and eGFR < 60 ml/min/1.73 m2 that will prevent a considerable number of aged healthy persons, as much as 1.700.000 in Spain and 2.600.000 in U.K., to be excluded from clinical assays or treatments contraindicated in CRI.

    Assessment of the health and economic impacts of PM2.5 pollution is of great importance for urban air pollution prevention and control. In this study, we evaluate the damage of PM2.5 pollution using Beijing as an example. First, we use exposure-response functions to estimate the adverse health effects due to PM2.5 pollution. Then, the corresponding labour loss and excess medical expenditure are computed as two conducting variables. Finally, different from the conventional valuation methods, this paper introduces the two conducting variables into the computable general equilibrium (CGE) model to assess the impacts on sectors and the whole economic system caused by PM2.5 pollution. The results show that, substantial health effects of the residents in Beijing from PM2.5 pollution occurred in 2013, including 20,043 premature deaths and about one million other related medical cases. Correspondingly, using the 2010 social accounting data, Beijing gross domestic product loss due to the health impact of PM2.5 pollution is estimated as 1286.97 (95% CI: 488.58-1936.33) million RMB. This demonstrates that PM2.5 pollution not only has adverse health effects, but also brings huge economic loss.

    About 18 years ago, a large-scale discontinuous layer in properties and colour was found in the new Fengjie town at the shore of the Three Gorges Reservoir area in China. There are many resettled residents and buildings on the sloping area, the safety of which is potentially affected by this layer, so it has become the focus of attention. Before this study started there were two viewpoints regarding the origin of this layer. One was that is was from a huge ancient slide and the other was that is was from a fault graben. In order to find out how it was formed and to be able to carry out a stability analysis of the slope the authors have carried out a research program, including geological field investigations and mapping, a deep drilling hole, a geotechnical centrifuge model test, and a simulation analysis. The results of the research led to the conclusion that the layer is the sliding plane of a huge deep-seated ancient rock slide, which we called the Sanmashan landslide. An important argument for the conclusion is the recognition of a regional compressive tectonic stress field in this area, which cannot lead to the formation of a fault graben because it needs a tensional tectonic stress field. Moreover, numerous unique geological features, sliding marks, and other relics of the ancient slide have been discovered in the field. The formation process of the ancient slide could be repeated in a large geotechnical centrifuge model test. The test shows that a deformation and failure process of "creep-crack-cut" has occurred. The type of the ancient slide can be classified as a "successive rotational rock slide". Finally, the role of seepage in the stability of the Sanmashan landslide has been analysed. Our final conclusions are that, during rainfall and filling-drawdown cycles in the Three Gorges Reservoir, the Sanmashan landslide as a whole is dormant and stable and the secondary landslides in the toe area of the slope are presently stable but can be reactivated.

    A clinical trial of radiotherapy with modified simultaneous integrated boost (SIB) technique against huge tumors was conducted. A 58-year-old male patient who had a huge pelvic tumor diagnosed as a rectal adenocarcinoma due to familial adenomatous polyposis was enrolled in this trial. The total dose of 77 Gy (equivalent dose in 2 Gy/fraction) and 64.5 Gy was delivered to the center of the tumor and the surrounding area respectively, and approximately 20% dose escalation was achieved with the modified SIB technique. The tumor with an initial maximum size of 15 cm disappeared 120 d after the start of the radiotherapy. Performance status of the patient improved from 4 to 0. Radiotherapy with modified SIB may be effective for patients with a huge tumor in terms of tumor shrinkage/disappearance, improvement of QOL, and prolongation of survival.

    The objective of this study was to introduce and evaluate a method for MR-based attenuation and truncation correction in phantom and patient measurements to improve PET quantification in PET/MR hybrid imaging. The fully MR-based method HUGE (B0 Homogenization using gradient enhancement) provides field-of-view extension in MR imaging, which can be used for truncation correction and improved PET quantification in PET/MR hybrid imaging. The HUGE method in this recent implementation is combined with continuously moving table data acquisition to provide a seamless nontruncated whole-body data set of the outer patient contours to complete the established standard MR-based Dixon-VIBE data for attenuation correction. The method was systematically evaluated in NEMA standard phantom experiments to investigate the impact of HUGE truncation correction on PET quantification. The method was then applied to 24 oncologic patients in whole-body PET/MR hybrid imaging. The impact of MR-based truncation correction with HUGE on PET data was compared to the impact of the established PET-based MLAA algorithm for contour detection. In phantom and in all patient measurements, the standard Dixon-VIBE attenuation correction data show geometric distortions and signal truncations at the edges of the MR imaging field-of-view. In contrast, the Dixon-VIBE-based attenuation correction data additionally extended by applying HUGE shows significantly less distortion and truncations and due to the continuously moving table acquisition robustly provides smooth outer contours of the patient arms. In the investigated patient cases, MLAA frequently showed an overestimation of arm volume and associated artifacts limiting contour detection. When applying HUGE, an average relative increase in SUVmean in patients' lesion of 4.2% and for MLAA of 4.6% were measured, when compared to standard Dixon-VIBE only. In specific lesions maximal differences in SUVmean up to 13% for HUGE and 14% for MLAA were measured

These attacks devastate societies causing huge economic loss with negative growth effects. Recent attacks suspectively conducted by Boko Haram in the north of Nigeria and along its border with Cameroon and Chad are already inflicting damage to local economies with a general drop in savings, investment, trade and a strain on domestic budgets. Poverty and exclusion generate dissidents and reactionary groups activities such as Boko Haram. But, the historical background permits to understand the emergency and the development of some of them. Tackling the Boko Haram threat requires a concerted multinational approach with a key socioeconomic component that incorporates the fact that conflict thrives better in circumstances of poverty and inequality.

    Paper presents the results of experimental studies on thermophysical properties of boron nitride (BN) plate-like shaped particles in ethylene glycol (EG). Essentially, the studies were focused on the thermal conductivity of suspensions of these particles. Nanofluids were obtained with two-step method (by dispersing BN particles in ethylene glycol) and its’ thermal conductivity was analyzed at various mass concentrations, up to 20 wt. %. Thermal conductivity was measured in temperature range from 293.15 K to 338.15 K with 15 K step. The measurements of thermal conductivity of nanofluids were performed in the system based on a device using the transient line heat source method. Studies have shown that nanofluids’ thermal conductivity increases with increasing fraction of nanoparticles. The results of studies also presented that the thermal conductivity of nanofluids changes very slightly with the increase of temperature. - Highlights: • Huge thermal conductivity enhancement in BN-EG nanofluid was reported. • Thermal conductivity increase very slightly with increasing of the temperature. • Thermal conductivity increase linearly with volume concentration of particles.

  13. Synovial sarcoma presenting with huge mediastinal mass: a case report and review of literature

    Science.gov (United States)

    2013-01-01

    Background Synovial sarcoma presenting in the mediastinum is exceedingly rare. Furthermore, data addressing optimal therapy is limited. Herein we present a case where an attempt to downsize the tumor to a resectable state with chemotherapy was employed. Case presentation A 32 year female presented with massive pericardial effusion and unresectable huge mediastinal mass. Computed axial tomography scan - guided biopsy with adjunctive immunostains and molecular studies confirmed a diagnosis of synovial sarcoma. Following three cycles of combination Ifosfamide and doxorubicin chemotherapy, no response was demonstrated. The patient refused further therapy and had progression of her disease 4 months following the last cycle. Conclusion Synovial sarcoma presenting with unresectable mediastinal mass carry a poor prognosis. Up to the best of our knowledge there are only four previous reports where primary chemotherapy was employed, unfortunately; none of these cases had subsequent complete surgical resection. Identification of the best treatment strategy for patients with unresectable disease is warranted. Our case can be of benefit to medical oncologists and thoracic surgeons who might be faced with this unique and exceedingly rare clinical scenario. PMID:23800262

    Peierls theory predicted atomic distortion in one-dimensional (1D) crystal due to its intrinsic instability in 1930. Free-standing carbon atomic chains created in situ in transmission electron microscope (TEM)1-3 are an ideal example to experimentally observe the dimerization behavior of carbon atomic chain within a finite length. We report here a surprisingly huge distortion found in the free-standing carbon atomic chains at 773 K, which is 10 times larger than the value expected in the system. Such an abnormally distorted phase only dominates at the elevated temperatures, while two distinct phases, distorted and undistorted, coexist at lower or ambient temperatures. Atom-by-atom spectroscopy indeed shows considerable variations in the carbon 1s spectra at each atomic site but commonly observes a slightly downshifted π* peak, which proves its sp(1) bonding feature. These results suggest that the simple model, relaxed and straight, is not fully adequate to describe the realistic 1D structure, which is extremely sensitive to perturbations such as external force or boundary conditions.

  15. A Huge Capital Drop with Compression of Femoral Vessels Associated with Hip Osteoarthritis

    Tomoya Takasago

    2015-01-01

    Full Text Available A capital drop is a type of osteophyte at the inferomedial portion of the femoral head commonly observed in hip osteoarthritis (OA, secondary to developmental dysplasia. Capital drop itself is typically asymptomatic; however, symptoms can appear secondary to impinge against the acetabulum or to irritation of the surrounding tissues, such as nerves, vessels, and tendons. We present here a case of unilateral leg edema in a patient with hip OA, caused by a huge bone mass occurring at the inferomedial portion of the femoral head that compressed the femoral vessels. We diagnosed this bone mass as a capital drop secondary to hip OA after confirming that the mass occurred at least after the age of 63 years based on a previous X-ray. We performed early resection and total hip arthroplasty since the patient’s hip pain was due to both advanced hip OA and compression of the femoral vessels; moreover, we aimed to prevent venous thrombosis secondary to vascular compression considering the advanced age and the potent risk of thrombosis in the patient. A large capital drop should be considered as a cause of vascular compression in cases of unilateral leg edema in OA patients.

    Full Text Available The association of pregnancy and torsion of bilateral huge benign ovarian cyst is rare. We report a case of multigravida at 13 weeks of pregnancy presenting with acute onset of lower abdominal pain. Ultrasound revealed bilateral multiloculated ovarian cysts of size 10x10 cm on right side and 15x10cm on left side with evidence of torsion and a single live intrauterine fetus of gestational age 13 weeks 4 days. Emergency laparotomy was done with vaginal susten 200 mg as perioperative tocolysis. Intra operatively, uterus was enlarged to 14 weeks size. Both ovaries were replaced with multiloculated cysts of size 15x10 cm on left side and 10x10 cm on right side. Ovarian pedicle was found to be twisted once on right side and twice on left side. On right side, untwisting of pedicle was done and the ovarian cyst was punctured at multiple sites to drain the clear fluid. Biopsy was taken from the right ovarian cyst wall. On left side, ovariotomy was done. Histopathology revealed mucinous cyst adenoma of left ovary and multiple corpus luteum in right ovarian biopsy specimen. The patient was followed up with regular antenatal check-ups and ultrasound to rule out the recurrence of ovarian cyst on right side. The patient successfully delivered a term male baby at 39 weeks.

    Full Text Available Background. Infantile hemangiomas (IHs are the most common benign tumours of infancy. Propranolol has recently been reported to be a highly effective treatment for IHs. This study aimed to evaluate the efficacy and side effects of propranolol for treatment of complicated cases of IHs. Patients and Methods. This prospective clinical study included 30 children with huge or complicated IHs; their ages ranged from 2 months to 1 year. They were treated by oral propranolol. Treatment outcomes were clinically evaluated. Results. Superficial cutaneous hemangiomas began to respond to propranolol therapy within one to two weeks after the onset of treatment. The mean treatment period that was needed for the occurrence of complete resolution was 9.4 months. Treatment with propranolol was well tolerated and had few side effects. No rebound growth of the tumors was noted when propranolol dosing stopped except in one case. Conclusion. Propranolol is a promising treatment for IHs without obvious side effects. However, further studies with longer follow-up periods are needed.

    I present here a review of past and present multi-disciplinary research of the Pittsburgh Computational AstroStatistics (PiCA) group. This group is dedicated to developing fast and efficient statistical algorithms for analysing huge astronomical data sources. I begin with a short review of multi-resolutional kd-trees which are the building blocks for many of our algorithms. For example, quick range queries and fast n-point correlation functions. I will present new results from the use of Mixture Models (Connolly et al. 2000) in density estimation of multi-color data from the Sloan Digital Sky Survey (SDSS). Specifically, the selection of quasars and the automated identification of X-ray sources. I will also present a brief overview of the False Discovery Rate (FDR) procedure (Miller et al. 2001a) and show how it has been used in the detection of ``Baryon Wiggles'' in the local galaxy power spectrum and source identification in radio data. Finally, I will look forward to new research on an automated Bayes Netw...

  19. Distributed data organization and parallel data retrieval methods for huge laser scanner point clouds

    This paper proposes a novel method for distributed data organization and parallel data retrieval from huge volume point clouds generated by airborne Light Detection and Ranging (LiDAR) technology under a cluster computing environment, in order to allow fast analysis, processing, and visualization of the point clouds within a given area. The proposed method is suitable for both grid and quadtree data structures. As for distribution strategy, cross distribution of the dataset would be more efficient than serial distribution in terms of non-redundant datasets, since a dataset is more uniformly distributed in the former arrangement. However, redundant datasets are necessary in order to meet the frequent need of input and output operations in multi-client scenarios: the first copy would be distributed by a cross distribution strategy while the second (and later) would be distributed by an iterated exchanging distribution strategy. Such a distribution strategy would distribute datasets more uniformly to each data server. In data retrieval, a greedy algorithm is used to allocate the query task to a data server, where the computing load is lightest if the data block needing to be retrieved is stored among multiple data servers. Experiments show that the method proposed in this paper can satisfy the demands of frequent and fast data query.

  20. Ecological economics and economic growth.

    2010-01-01

    Boulding's 1966 paper on the economics of spaceship Earth established the framework for ecological economics and an understanding of economic growth. In ecological economics, economies are conceptualized as open subsystems of the closed biosphere and are subject to biophysical laws and constraints. Economic growth measured as an increase in real gross domestic product (GDP) has generally been associated with increases in the use of energy and materials and the generation of wastes. Scale, composition, and technology are the proximate determinants of environmental impacts. They are often reduced to two: scale (GDP) and intensity (impact per unit GDP). New work described in this paper defines "green" growth as intensity that declines faster than scale increases. Similarly, "brown" growth occurs when intensity declines more slowly than increases in scale, and "black" growth happens when both scale and intensity increase. These concepts are then related to the environmental Kuznets curve, which can be understood as a transition from brown to green growth. Ecological economics provides a macroperspective on economic growth. It offers broad policy principles, and it challenges the primacy of economic growth as a policy objective, but many important questions remain.

    The Authors (Avnery et al., 2011a,b) estimated the relative yield losses of wheat crop in China in 2000 and 2030 to be 15%-20% and 25%-30%, respectively. And the relative yield losses of soybean crop in China in 2000 and 2030 to be 20%-25% and 30%-45%, respectively. These findings do not agree with the information that shows the relative yield losses of wheat crop should be greater than those of soybean crop in China. Additionally, do not agree with the findings of previous studies.

    Recent worldwide earthquakes have resulted in staggering losses. The Northridge, California; Kobe, Japan; Loma Prieta, California; Izmit, Turkey; Chi-Chi, Taiwan; and Bhuj, India earthquakes, which range from magnitudes 6.7 to 7.7, have all occurred near populated areas. These earthquakes have resulted in estimated losses between \\3 and \\300 billion, with tens to tens of thousands of fatalities. Subduction zones are capable of producing the largest earthquakes. The 1939 M7.8 Chilean, the 1960 M9.5 Chilean, the 1964 M9.2 Alaskan, the 1970 M7.8 Peruvian, the 1985 M7.9 Mexico City and the 2001 M7.7 Bhuj earthquakes are damaging subduction zone quakes. The Cascadia fault zone poses a tremendous hazard in the Pacific Northwest due to the ground shaking and tsunami inundation hazards combined with the population. To address the Cascadia subduction zone threat, the Oregon Department of Geology and Mineral Industries conducted a preliminary statewide loss study. The 1998 Oregon study incorporated a M8.5 quake, the influence of near surface soil effects and default building, social and economic data available in FEMA's HAZUS97 software. Direct financial losses are projected at over \\$12 billion. Casualties are estimated at about 13,000. Over 5,000 of the casualties are estimated to result in fatalities from hazards relating to tsunamis and unreinforced masonry buildings.

This study was to investigate the clinical and angiographic outcomes of the treatment of the huge dissecting aneurysms involving the BA by the internal trapping (IT technique. Methods: We retrospectively studied 15 patients with the huge dissecting aneurysms involving the BA treated by the IT technique between September 2005 and September 2014 in Department of Interventional Neuroradiology of Beijing Tiantan Hospital. Clinical and angiographic data were reviewed and evaluated. Results: All patients were treated by the IT technique. That meant the dissecting artery and aneurysm segments were completed occlusion. After the procedure, the angiography demonstrated that all the dissecting artery and aneurysm segments were completed occlusion. Follow-up angiography was performed at 3-6 months or 12-18 months after the endovascular treatment (median 8 months, 14 patients had a good recovery. Re-canalization occurred in one patient whose aneurysm involved in bilateral vertebral arteries and the two third of the middle-lower BA. After the second treatment, the patient died by the ventricular tachycardia. Conclusions: The IT technique is a technically feasible and safe alternative for the treatment of BA dissecting aneurysms, but it is not necessarily the safest or most definitive treatment modality. The ideal treatment of the huge dissecting aneurysms involving the BA remains debatable and must be investigated on a case-by-case basis.

    Case report and review of relevant literature. To discuss the surgical strategies and clinical outcome of managing huge tear drop fracture of axis. Teardrop fracture of axis is rarely seen, especially the huge type. The surgical technique is demanding because of the special anatomical structure and difficulty with bone grafting. Moreover, the surgical approach is controversial in the literature. A 51-year-old male patient suffered from neck pain after falling from the bicycle, neck movement was limited with no neurological compromise. X-ray suggested huge tear-drop fracture of anterior-inferior corner of axis, narrowing of C2/3 intervertebral disc. Fusion with self-designed tricortical trapezoidal iliac bone was performed. Treating huge teardrop fracture of axis by anterior bone grafting with self-designed tricortical trapezoidal iliac bone is effective and stable. A 3-month follow-up showed fusion was achieved, upper cervical curvature was restored, and neck pain disappeared. Self-designed tricortical trapezoidal iliac bone provided adequate fusion area of bone grafting, restoring the normal intervertebral height and cervical alignment, and the midterm outcome is satisfactory. 5.

    Complete cytoreductive surgery (CCRS) plus Hyperthermic Intraperitoneal Chemotherapy (HIPEC) is the best-known treatment for pseudomyxoma peritonei (PMP). In 30% of the cases, PMP realize a widespread involvement of the peritoneal cavity. In these extreme situations, we developed, devoted strategies to optimize the feasibility and safety of CCRS. This study describes the surgical resections required for CCRS and the consequent approaches that we propose to achieve CCRS. We defined "huge PMP" by a peritoneal cancer index (PCI) ≥ 28. Surgical procedures of patients operated on between 1994 and 2014 were retrospectively reviewed from a prospective database in a single institution. During this period, 311 patients were operated on and 247 (79%) underwent CCRS + HIPEC. Among them, 100 patients presented "huge" PMP and 54 patients underwent CCRS + HIPEC. In patients with "huge" PMP, the rate of CCRS + HIPEC was 25% before 2002 and reached 71% between 2011 and 2014. We identified 3 conditions for CCRS 1) to guaranty a sufficient length of residual small bowel 2) to preserve the left gastric vessels in order to preserve the superior third of the stomach 3) to ensure that the hepatic pedicle can be entirely cleared from its tumor involvement. None of the other peritonectomy procedures were decisional for CCRS. Our learning curve improved the selection and completion rate of CCRS + HIPEC for "huge PMP". Some anatomical and physiological prerequisites guarantee the feasibility and safety of such extensive surgeries. Copyright © 2016 Elsevier Ltd. All rights reserved.

    This retrospective study aimed to validate the safety and effectiveness of hepatectomy for huge hepatocellular carcinoma (HCC). Data of patients who underwent hepatectomy for HCC between January 2006 and December 2012 were reviewed. The patients were divided into three groups: huge HCC(≥ 10 cm in diameter), large HCC(≥ 5 buthuge and large HCC groups were lower than that of the small HCC group (OS: 32.5% vs 36.3% vs 71.2%, p=0.000; DFS: 20.0% vs 24.8% vs 40.7%, p=0.039), but there was no difference between the huge and large HCC groups (OS: 32.5% vs 36.3%, p=0.667; DFS: 20.0% vs 24.8%, p=0.540). In multivariate analysis, five independent poor prognostic factors that affected OS were significantly associated with worse survival (phuge HCC is similar to that for large and small HCC; and this approach for huge HCC may achieve similar long-term survival and disease-free survival as for large HCC.

    Huge goiters are common in iodine-deficient endemic regions. They are of concern to the surgeons because of the anticipated risk of difficult dissection and increased chances of surgical complications. Similarly, they are of concern to the anesthesiologists because of anticipated intubation-related difficulties and post-thyroidectomy tracheomalacia. In the present study we aimed to present our experience of managing goiters based on their gross weight, highlighting their clinicopathological profile, perioperative airway-related difficulties, and management of surgical morbidity. Retrospective analysis of patients who underwent total thyroidectomy in the primary setting at our institute from 1995 to 2009 was carried out based on the gross gland weight. The patients were thus grouped into group A: ≤200 g; group B: 201 to ≤400 g; group C: 401 to ≤600 g; group D: >600 g. Group A (660 cases); group B (108 cases); group C (36 cases); and group D (9 cases) were included. As the goiter size increased, the mean duration of goiter, compressive symptoms, retrosternal extension (RSE), airway deformity, intubation difficulty, and tracheomalacia increased. The rate of tracheostomy, sternotomy, hemorrhage, visceral injury, and hospital stay was high with huge goiters. These features were more marked in malignant goiters compared to benign goiters. However, the postoperative complications were comparable in both of those groups. Long-standing huge goiters are common in iodine-deficient endemic areas. The majority of patients have symptomatic or clinicoradiological evidence of airway involvement. The incidence of RSE, airway deformity, intubation difficulty, and tracheomalacia is high with huge goiters. The surgery is technically demanding with greater associated chances of injury to native structures. Malignancy influences the presentation and outcome in smaller goiters. In centers with experienced endocrine surgeons and dedicated anesthetists, huge goiters can be

Although initial applications focused on consumer behavior, such as explaining why people failed to save adequately for retirement, the field has moved increasingly into the area of explaining health behaviors as well as the design of lifestyle interventions, such as weight loss and smoking-cessation programs. This article provides an overview of several important behavioral economics concepts of relevance to public health and health behavior change.

  2. The economics of natural disasters

    Hallegatte, S.

    2007-05-01

    Mitigating natural disasters is probably more important for society than it can be inferred from direct losses. Total economic losses, indeed, can be much larger than direct losses, especially for large disasters, which affect the economy for extended periods of time (e.g., New Orleans after Katrina), and represent an important obstacle to economic development in certain regions (e.g. Central America). A series of recent modelling exercises highlights several findings. First, total economic losses due to an event are increasing nonlinearly as a function of its direct losses, because destructions both increase reconstruction needs and reduce reconstruction capacity. Second, endogenous economic dynamics has to be taken into account in the assessment of disaster consequences. More particularly, an economy in the expansion phase of its business cycle appears to be more vulnerable to extreme events than an economy in recession. This result is supported by the fact that worker availability is found to be one of the main obstacles to a rapid and efficient reconstruction. Third, natural disasters can create poverty traps for poor countries, which have a lower ability to fund and carry out reconstruction. As a consequence, climate change impacts from extreme events may be significant, and will depend on how societies are able to adapt their reconstruction capacity to new levels of risk.

    In federal fiscal year 2000 (FY00), Berkeley Lab had 4,347 full- and part-time employees. In addition, at any given time of the year, there were more than 1,000 Laboratory guests. These guests, who also reside locally, have an important economic impact on the nine-county Bay Area. However, Berkeley Lab's total economic impact transcends the direct effects of payroll and purchasing. The direct dollars paid to the Lab's employees in the form of wages, salaries, and benefits, and payments made to contractors for goods and services, are respent by employees and contractors again and again in the local and greater economy. Further, while Berkeley Lab has a strong reputation for basic scientific research, many of the Lab's scientific discoveries and inventions have had direct application in industry, spawning new businesses and creating new opportunities for existing firms. This analysis updates the Economic Impact Analysis done in 1996, and its purpose is to describe the economic and geographic impact of Laboratory expenditures and to provide a qualitative understanding of how Berkeley Lab impacts and supports the local community. It is intended as a guide for state, local, and national policy makers as well as local community members. Unless otherwise noted, this analysis uses data from FY00, the most recent year for which full data are available.

  13. [Economic crime].

    Science.gov (United States)

    Dinitz, S

    1976-01-01

    Economic crime, often also referred to as white collar crime, is one of the most incidious and predatory of offenses. Unlike street crime, for which there may well be some protection, the average citizen is completely at the mercy of the perpetrators of economic crimes. The concept of white collar crime was first identified by Edwin H. Sutherland. He dealt with the problem as a violation of trust involving either or both misrepresentation and duplicity. He argued for the use of criminal sanctions rather than civil remedies as a means of dealing with white collar offenses. Sutherland's views were attacked by the legal profession, by sociologists and criminologists and by public opinion specialists. They contended that an act treated in civil court is not a crime; that criminals are those persons who are defined as such and white collar criminals are neither so defined nor do they define themselves as criminals and, finally, that economic crime is universal. Can anyone be criminal, then, ask the critics? A number of studies by Clinard, Quinney, Black, Ball, Cressey, Newman and others have translated the interest in white collar crime into empirical terms. The last thirty-five years have also witnessed the elaboration and alteration of the theory itself. Geis' work has been particularly important in this respect. His "street" versus "suite" crime is a useful dichotomy. Most important, however, have been the monograph and papers by Herbert Edelhertz who has conceptualized the issues on various levels - from consumer fraud to the illegal activities of the multinational corporation. This article is concerned with the exposition of the theory and research in the field. Most significant, the paper raises serious doubts whether the problem of economic crime can be researched and studied; it raises even more difficult issues concerning the legal and sociological implications of economic crime and of its prevention, management and control.

  14. Economics of human trafficking.

    Wheaton, Elizabeth M; Schauer, Edward J; Galli, Thomas V

    2010-01-01

    Because freedom of choice and economic gain are at the heart of productivity, human trafficking impedes national and international economic growth. Within the next 10 years, crime experts expect human trafficking to surpass drug and arms trafficking in its incidence, cost to human well-being, and profitability to criminals (Schauer and Wheaton, 2006: 164-165). The loss of agency from human trafficking as well as from modern slavery is the result of human vulnerability (Bales, 2000: 15). As people become vulnerable to exploitation and businesses continually seek the lowest-cost labour sources, trafficking human beings generates profit and a market for human trafficking is created. This paper presents an economic model of human trafficking that encompasses all known economic factors that affect human trafficking both across and within national borders. We envision human trafficking as a monopolistically competitive industry in which traffickers act as intermediaries between vulnerable individuals and employers by supplying differentiated products to employers. In the human trafficking market, the consumers are employers of trafficked labour and the products are human beings. Using a rational-choice framework of human trafficking we explain the social situations that shape relocation and working decisions of vulnerable populations leading to human trafficking, the impetus for being a trafficker, and the decisions by employers of trafficked individuals. The goal of this paper is to provide a common ground upon which policymakers and researchers can collaborate to decrease the incidence of trafficking in humans.

  15. Climate change adaptation accounting for huge uncertainties in future projections - the case of urban drainage

    Willems, Patrick

    2015-04-01

    Hydrological design parameters, which are currently used in the guidelines for the design of urban drainage systems (Willems et al., 2013) have been revised, taking the Flanders region of Belgium as case study. The revision involved extrapolation of the design rainfall statistics, taking into account the current knowledge on future climate change trends till 2100. Uncertainties in these trend projections have been assessed after statistically analysing and downscaling by a quantile perturbation tool based on a broad ensemble set of climate model simulation results (44 regional + 69 global control-scenario climate model run combinations for different greenhouse gas scenarios). The impact results of the climate scenarios were investigated as changes to rainfall intensity-duration-frequency (IDF) curves. Thereafter, the climate scenarios and related changes in rainfall statistics were transferred to changes in flood frequencies of sewer systems and overflow frequencies of storage facilities. This has been done based on conceptual urban drainage models. Also the change in storage capacity required to exceed a given overflow return period, has been calculated for a range of return periods and infiltration or throughflow rates. These results were used on the basis of the revision of the hydraulic design rules of urban drainage systems. One of the major challenges while formulating these policy guidelines was the consideration of the huge uncertainties in the future climate change projections and impact assessments; see also the difficulties and pitfalls reported by the IWA/IAHR Joint Committee on Urban Drainage - Working group on urban rainfall (Willems et al., 2012). We made use of the risk concept, and found it a very useful approach to deal with the high uncertainties. It involves an impact study of the different climate projections, or - for practical reasons - a reduced set of climate scenarios tailored for the specific type of impact considered (urban floods in our

    To evaluate the clinical efficacy of CT-guided percutaneous huge ilio-psoas abscesses drainage combined with posterior approach surgery for the management of dorsal and lumbar spinal tuberculosis in 16 adult cases. Between January 2006 and June 2013, a total of 16 dorsal and lumbar spinal tuberculosis patients with huge ilio-psoas abscesses underwent two-stage CT-guided percutaneous abscesses drainage and posterior debridement, decompression, intervertebral fusion and instrumentation. Standard quadruple antituberculous chemotherapy was performed both before and after surgery. The average follow-up period was 26.7 months (range 18-38 months). There is no severe complication and relapse of spinal tuberculosis. The blood loss was 921.0±141.3mL, operation time was 174.8±15.7minutes. Kyphotic angle improved from 36.6±10.0° preoperatively to 8.1±1.8° postoperatively with 2.2±1.5° loss of correction at final follow-up. The solid bone fusion was achieved in all cases at average 6.6±2.2 months after surgery. Neurologic deficits were recovered in varing degrees except 4 cases remained the same. The postoperative quality of life significantly improved. The Oswestry Disability Index (ODI) decreased from 32.8±10.6 preoperatively to 14.4±7.9 at the final follow-up. CT-guided percutaneous drainage combined with posterior approach surgery was proved to be safe and effective for the management of dorsal and lumbar spinal tuberculosis with huge ilio-psoas abscesses in adults.

    Only ten cases of neonatal congenital segmental dilatation (CSD) of the colon have been described so far. We present a full-term female newborn with trisomy 21, ventricular septal defect, and gross abdominal distension. Plain abdominal radiographs revealed a huge cystic lesion occupying the left hemiabdomen. Upon laparotomy on day 4 a CSD of the distal sigmoid and proximal rectum was confirmed and resected. The proximal colon was exteriorized and the distal part closed as a Hartmann pouch. Histology confirmed a huge segmental dilatation of the sigmoid without dysganglionosis or pseudodiverticula, but normal intestinal architecture. After correction of the ventricular septal defect a low rectal end-to-end anastomosis could be performed at an age of 5 months. The postoperative course was uneventful. CSD of the sigmoid colon is extremely "rare to meet" and a "challenge to treat" in the newborn period, but clinical awareness of this entity prompts pediatric surgical success.

    This study aimed to introduce a method to remove huge ovarian tumors (≥15 cm) intact with single-port laparoscopic surgery (SPLS) using SW Kim's technique and to compare the surgical outcomes with those of laparotomy. Medical records were retrospectively reviewed for patients who underwent either SPLS (n=21) with SW Kim's technique using a specially designed 30×30-cm(2)-sized 3XL LapBag or laparotomy (n=22) for a huge ovarian tumor from December 2008 to May 2016. Perioperative surgical outcomes were compared. In 19/21 (90.5%) patients, SPLS was successfully performed without any tumor spillage or conversion to multi-port laparoscopy or laparotomy. There was no significant difference in patient characteristics, including tumor diameter and total operation time, between both groups. The postoperative hospital stay was significantly shorter for the SPLS group than for the laparotomy group (median, 2 [1 to 5] vs. 4 [3 to 17] days; Phuge ovarian tumors.

  19. Financial Bubbles, Real Estate Bubbles, Derivative Bubbles, and the Financial and Economic Crisis

    Sornette, Didier; Woodard, Ryan

    The financial crisis of 2008, which started with an initially well-defined epicenter focused on mortgage backed securities (MBS), has been cascading into a global economic recession, whose increasing severity and uncertain duration has led and is continuing to lead to massive losses and damage for billions of people. Heavy central bank interventions and government spending programs have been launched worldwide and especially in the USA and Europe, with the hope to unfreeze credit and bolster consumption. Here, we present evidence and articulate a general framework that allows one to diagnose the fundamental cause of the unfolding financial and economic crisis: the accumulation of several bubbles and their interplay and mutual reinforcement have led to an illusion of a "perpetual money machine" allowing financial institutions to extract wealth from an unsustainable artificial process. Taking stock of this diagnostic, we conclude that many of the interventions to address the so-called liquidity crisis and to encourage more consumption are ill-advised and even dangerous, given that precautionary reserves were not accumulated in the "good times" but that huge liabilities were. The most "interesting" present times constitute unique opportunities but also great challenges, for which we offer a few recommendations.

    A comprehensive methodology for economic consequence analysis with appropriate models for risk analysis of process systems is proposed. This methodology uses loss functions to relate process deviations in a given scenario to economic losses. It consists of four steps: definition of a scenario, identification of losses, quantification of losses, and integration of losses. In this methodology, the process deviations that contribute to a given accident scenario are identified and mapped to assess potential consequences. Losses are assessed with an appropriate loss function (revised Taguchi, modified inverted normal) for each type of loss. The total loss is quantified by integrating different loss functions. The proposed methodology has been examined on two industrial case studies. Implementation of this new economic consequence methodology in quantitative risk assessment will provide better understanding and quantification of risk. This will improve design, decision making, and risk management strategies.

    Tumor recurrence is very common after resection of huge hepatocellular carcinoma (HCC). This study intended to evaluate early recurrence and long-term outcomes in patients with huge HCC ≥ 10 cm after primary resection and treatment of recurrence. Recurrence and survival outcomes were retrospectively evaluated in 471 patients with huge HCCs who underwent resection between January 2000 and April 2012. Mean tumor diameter was 13.6 ± 3.1 cm, with 93 % of patients having single tumors. Anatomic and R0 resection rates were 91.1 and 89.4 %, respectively. Perioperative mortality rate was 1.7 %. Tumor recurrence and patient survival rates were 62.2 and 69.2 % at 1 year and 76.0 and 35.5 % at 5 years, respectively. Of patients with recurrence, 92.5 % received specific treatment. Median patient survival period after initial intrahepatic recurrence was 16 months. Tumor volume did not affect recurrence or survival outcomes. Independent risk factors for tumor recurrence and patient survival were serum alpha-fetoprotein ≥ 100 ng/mL, hypermetabolic uptake on positron emission tomography, satellite nodules, and microvascular invasion. These four factors were used to develop a risk prediction model, in which 1-year HCC recurrence rates in patients with 0, 1, 2, 3, and 4 risk factors were 18.7, 30.3, 58.7, 79.0, and 92.1 %, respectively, and their 1-year patient survival rates were 100, 97.0, 75.5, 63.9, and 42.1 %, respectively. In patients with huge HCCs, hepatic resection with active recurrence treatment resulted in improved long-term survival. Our 4-factor risk prediction model appears to contribute to quantitative postoperative risk estimation for early HCC recurrence and patient survival in patients with HCC ≥ 10 cm.

    Inflammation plays a critical role in tumor metastasis. However, few inflammation-related biomarkers are currently available to predict the risk of metastasis for advanced hepatocellular carcinoma (HCC). Using huge tumors (diameter >10 cm) as a model, we evaluated the potential risk of pre- and post-treatment inflammatory responses in the development of metastasis of HCC patients undergoing transarterial chemoembolization (TACE). A logistic regression model was used to analyze the risk factors. One hundred and sixty-five patients with huge HCC were enrolled in the study. Metastases were identified in 25.5% (42/165) patients by imaging evaluation post-TACE. Neutrophils increased, whereas lymphocytes decreased significantly post-TACE. Univariate analysis showed that high post-treatment neutrophil-to-lymphocyte ratio (NLR; p = 0.003), low post-treatment lymphocyte count (p = 0.047), and high baseline NLR (p = 0.100) were potential risk factors for metastasis. Further, multivariate analysis showed that high post-treatment NLR, but not pre-treatment NLR, was an independent risk factor for metastasis; this was confirmed by receiver operating characteristic curve analysis. Post-treatment NLR, however, had no correlation to tumor response and overall survival of patients. In conclusion, post-treatment NLR but not pre-treatment NLR independently increases the risk of metastasis in huge HCC. Our findings suggest the potential contribution of treatment-related inflammation to metastasis in advanced HCC.

    Inversion of the uterus is an extremely rare complication of the non-puerperal period and is commonly caused by benign submucous, especially fundal, leiomyomas. A case of a totally inverted cervix due to a prolapsed huge cervical leiomyoma mimicking chronic non-puerperal uterine inversion in a perimenopausal woman is presented. A 52-year-old perimenopausal woman was admitted to our clinic with an ulcerated, necrotic, infected and swollen prolapsed mass. Gynecologic history revealed that she was advised myomectomy because of her cervical myoma 2 years ago but she refused to have an operation as she believed that her positive thoughts would shrink the myoma. Presumed diagnosis before surgery was chronic non-puerperal uterine inversion. An intraoperative diagnosis was totally inverted cervix due to a huge cervical leiomyoma. Vaginal hysterectomy without adnexectomy, was performed. This is the first case in the literature which a totally inverted cervix due to a prolapsed huge cervical leiomyoma. Cervical fibroids can grow in perimenopausal period and in extremely rare cases can cause total cervical inversion. Copyright © 2014 The Authors. Published by Elsevier Ltd.. All rights reserved.

    The Energy Policy and Conservation Act (EPCA) mandated that minimum energy efficiency standards be established for classes of refrigerators and refrigerator-freezers, freezers, clothes dryers, water heaters, room air conditioners, home heating equipment, kitchen ranges and ovens, central air conditioners, and furnaces. EPCA requires that standards be designed to achieve the maximum improvement in energy efficiency that is technologically feasible and economically justified. Following the introductory chapter, Chapter Two describes the methodology used in the economic analysis and its relationship to legislative criteria for consumer product efficiency assessment; details how the CPES Value Model systematically compared and evaluated the economic impacts of regulation on the consumer, manufacturer and Nation. Chapter Three briefly displays the results of the analysis and lists the proposed performance standards by product class. Chapter Four describes the reasons for developing a baseline forecast, characterizes the baseline scenario from which regulatory impacts were calculated and summarizes the primary models, data sources and assumptions used in the baseline formulations. Chapter Five summarizes the methodology used to calculate regulatory impacts; describes the impacts of energy performance standards relative to the baseline discussed in Chapter Four. Also discussed are regional standards and other program alternatives to performance standards. Chapter Six describes the procedure for balancing consumer, manufacturer, and national impacts to select standard levels. Details of models and data bases used in the analysis are included in Appendices A through K.

    风暴潮是我国沿海省市面临的重大自然灾害之一,给这些地区造成了难以估量的损失。选取1989—2008年沿海11省、市、自治区风暴潮的历史数据作为研究样本,运用因子得分基础上的聚类分析和熵值评价等方法,对这些地区风暴潮灾害经济损失的风险进行了评估,最终按风暴潮灾害的经济损失程度将沿海省市划分为3个区域:即上海为第1区,表示风暴潮经济损失风险最小;海南、福建、浙江、广东4省为第3区,风险最大;其他省、市、自治区为第2区,表示经济损失风险居中。3个区域的灾害区划,为我们从更深层次上认识风暴潮的发生及是造成的损失情况提供了新的视角。%Storm surges is one of the major natural disasters in coastal area of China, which has caused incalculable loss. In this paper, we selected 11 coastal provinces ( municipalities, autonomous regions, ) ' storm surge data from the year 1989 to 2008 as a research sample, while the cluster analysis based on factor scores and evaluation of en- tropy methods were used to evaluate the disaster risk of storm surge in these areas. According to extent of loss, these areas can be divided into three kinds: Shanghai has the smallest risk of storm surge disaster as the First District; the provinces of Hainan, Fujian, Zhejiang and Guangdong have the greatest risk as the Second District; the other provinces( municipality, autonomous region) have the medial risk as the Third District. This result gives us a new perspective to understand the occurrence of storm surge and the loss caused by it.

    Full Text Available Foot and mouth disease is probably the most important livestock disease in the world in terms of economic impact. Of all the vesicular diseases prevalent in India, FMD remains the greatest and most feared scourge. In Chazhoor Panchayat, 62 animals were affected with FMD, out of which 28 were vaccinated. The economic loss was calculated taking into consideration milk loss, losses due to abortion and treatment charges. The total economic loss was calculated as Rs 313900/- out of which loss in milk production accounted for 80.68%. Cost of milk was calculated at the rate of Rs. 12/ litre, to assess the economic loss. Treatment cost includes vehicle charges and cost of medicine. An average loss of 8 hrs/day/ animal was calculated. Vaccination cost of Rs. 5/ animal was also considered. Towards the nursing of animal and disinfection of shed, loss of manpower of 2-hrs/ animals for 5 days was calculated. [Veterinary World 2008; 1(1.000: 5-6

    Full Text Available The object of this article consists of establishing the relation between competitiveness and economic policy in the case of the People’s Republic of China in the period from 1948 to 2008. The hypothesis that is demonstrated throughout the presentation maintains that more than the macroeconomic stability, the economic growth is directly related to the type of economic policy that applies a nation, as it is the case of China. The historical antecedents (1948-1978, the economic policy in the days of the reform of the economy (1978-1998 and the present time in which the past and the present are crossed, constitute the huge landmarks of the work. The economic policy is analyzes in “sub political” such as the agriculturist, industrialist, prices, foreign trade, foreign affairs, fiscal, monetary, exchange and investment, competitiveness etc., taking the work to planes of better concretion.

  8. Widening economic & social disparities: implications for India.

    Science.gov (United States)

    Kurian, N J

    2007-10-01

    India is often characterized as an emerging economic super power. The huge demographic dividend, the high quality engineering and management talent, the powerful Indian diaspora and the emerging Indian transnational--kneeling the optimism. In contrast, there is another profile of India which is rather gloomy. This is the country with the largest number of the poor, illiterates and unemployed in the world. High infant mortality, morbidity and widespread anaemia among women and children continue. India suffers from acute economic and social disparities. This article addresses four dimensions of such disparities, viz. regional, rural-urban, social, and gender. There is empirical evidence to indicate that during the last two decades all these disparities have been increasing. As a result of economic reforms, the southern and western States experienced accelerated economic and social development as compared to northern and eastern States. This has led to widening gap in income, poverty and other indicators of development between the two regions. Rural-urban divide also widened in the wake of reforms. While large and medium cities experience unprecedented economic prosperity, the rural areas experience economic stagnation. As a result, there is widespread agrarian distress which results in farmers' suicide and rural unrest. Socially backward sections, especially scheduled castes and tribes (SCs and STs) have gained little from the new prosperity which rewards disproportionately those with assets, skills and higher education. STs have often been victims of development as a result of displacement. The gender gap in social and economic status, traditionally more in India as compared to other societies; has further widened by the economic reforms and globalization. The approach paper to the Eleventh Plan stresses the importance of more inclusive economic growth. It emphasizes the need for bridging the divides discussed in this article. Unless these are achieved in a time

    This study was conducted to evaluate the safety and efficacy of stereotactic body radiotherapy (SBRT) combined with transarterial chemoembolization (TACE) for huge (≥10 cm) hepatocellular carcinomas (HCCs). Between May, 2006 and December, 2012, 72 patients with huge HCCs were treated by SBRT following incomplete TACE. The median total dose of 35.6 Gy was delivered over 12-14 days with a fractional dose of 2.6-3.0 Gy and 6 fractions per week. The patients were classified into those with tumor encapsulation (group A, n=33) and those without tumor encapsulation (group B, n=39). The clinical outcomes of tumor response, overall cumulative survival and toxicities/complications were retrospectively analyzed. Among the 72 patients, CR, PR, SD and PD were achieved in 6 (8.3%), 51 (70.8%), 9 (12.5%) and 6 patients (8.3%), respectively, within a median follow-up of 18 months. The objective response rate was 79.1%. The overall cumulative 1-, 3- and 5-year survival rates and the median survival time were 38, 12 and 3% and 12.2 months, respectively. In group A, the overall cumulative 1-, 3- and 5-year survival rates were 56, 21 and 6%, respectively, with a median survival of 19 months; in group B, the overall cumulative 1-, 3- and 5-year survival rates were 23, 4 and 0%, respectively, with a median survival of 10.8 months (P=0.023). The treatment was well tolerated, with no severe radiation-induced liver disease and no reported > grade 3 toxicity. Tumor encapsulation was found to be a significant prognostic factor for survival. In conclusion, the combination of SBRT and TACE was shown to be a safe and effective treatment option for patients with unresectable huge HCC.

    The surgical approach to the jugular foramen has been considered to be very difficult and troublesome, because of the location in which important structures, such as the internal jugular vein, internal carotid artery and lower cranial nerves, converge in the narrow deep space. A case of huge neurofibroma, which extended from the tentorium cerebelli through the dilated jugular foramen to the level of the vertebral body of C/sub 3/ was presented. A 12-year-old girl was admitted with complaints of visual disturbance and palsy of the V-XII cranial nerves of the left side. Plain skull film showed prominent widening of the cranial sutures and enlargement of the sella turcica. Horizontal CT scan with contrast showed symmetrical ventricular dilatation and a heterogeneously enhanced mass, which was situated mainly in the left CP angle. Coronal CT scan with contrast revealed a huge mass and enlarged jugular foramen, through which the tumor extended to the level of the vertebral body of C/sub 3/. Occlusion of the sigmoid sinus and the internal jugular vein of the left side was noticed in the vertebral angiography. Two-stage approach, the first one for removal of the intracranial tumor and the second one for extracranial tumor, was performed for its huge tumor. Several authors have reported excellent surgical approaches for the tumors situated in the jugular foramen. By our approach, modifying Gardner's original one, a wide operative field was obtained to remove the tumor around the jugular foramen with success. Our approach for the jugular foramen was described with illustrations.

    Ectopic varices (EcV) are enlarged portosystemic venous collaterals, which usually develop secondary to portal hypertension (PHT). Mesocaval collateral vessels are unusual pathways to decompress the portal system. Here we report the case of a huge varicose inferior mesenteric vein (IMV) that drained into peri rectal collateral veins, demonstrated by {sup 99m}Tc-labeled red blood cell (RBC) scintigraphy performed for lower gastrointestinal (GI) bleeding in a 14-year-old girl. This case illustrates the crucial role of {sup 99m}Tc-labeled RBC scintigraphy for the diagnosis of rare ectopic lower GI varices.

    Physical extremes can be distinguished in "sudden physical extremes" (e.g. earthquakes, tsunami) and "progressive physical extremes" (e.g. drought, desertification, landslides). They differ for frequency, intensity, spatial extent, duration and timing of occurrence. If a physical extreme, by interacting with human systems, induces negative consequences, its outcome can be a "disaster". The disasters are, in both above cases, characterized by a few phases: physical extreme occurrence, emergency, response, and recovery. However, in the case of a progressive physical extreme, the disaster develops with an overlap in the time of the above-mentioned phases. When the events are repetitive, the emergency planning (which follows a cycle) succeeds with preparedness and mitigation with the intent of reducing the risk. Both the sudden and progressive physical extremes produce cascading effects of consequences on social, environmental and economic systems. Disasters consequent to sudden and progressive extremes show, however, some differences, mainly attributable to the "visibility" of the effects and to their time scale of evolution. As matter of fact, a disaster consequent to a progressive physical extreme produces "emerging signals" that are often invisible. Moreover, the emergency phase can arise with a time delay compared to the occurrence of the physical extreme, depending on the spatial scale of impacted system. The above differences allow defining "creeping disasters" the potential disasters related to progressive physical extremes. This study deals with some peculiar "cascading disasters" consequent to drought, which is the main "creeping disaster", namely the groundwater drought and the consequent salinization of coastal aquifers. In regional flow systems, their effects are invisible in the immediate to common people (and often even to managers) because of the concealed nature of groundwater; moreover, they are difficult to assess because of the shift over time of

    Huge livestock population of India is under threat by a large number of endemic infectious (bacterial, viral, and parasitic) diseases. These diseases are associated with high rates of morbidity and mortality, particularly in exotic and crossbred cattle. Beside morbidity and mortality, economic losses by these diseases occur through reduced fertility, production losses, etc. Some of the major infectious diseases which have great economic impact on Indian dairy industries are tuberculosis (TB), Johne’s disease (JD), mastitis, tick and tick-borne diseases (TTBDs), foot and mouth disease, etc. The development of effective strategies for the assessment and control of infectious diseases requires a better understanding of pathogen biology, host immune response, and diseases pathogenesis as well as the identification of the associated biomarkers. Indigenous cattle (Bos indicus) are reported to be comparatively less affected than exotic and crossbred cattle. However, genetic basis of resistance in indigenous cattle is not well documented. The association studies of few of the genes associated with various diseases, namely, solute carrier family 11 member 1, Toll-like receptors 1, with TB; Caspase associated recruitment domain 15, SP110 with JD; CACNA2D1, CD14 with mastitis and interferon gamma, BoLA­-DRB3.2 alleles with TTBDs, etc., are presented. Breeding for genetic resistance is one of the promising ways to control the infectious diseases. High host resistance is the most important method for controlling such diseases, but till today no breed is total immune. Therefore, work may be undertaken under the hypothesis that the different susceptibility to these diseases are exhibited by indigenous and crossbred cattle is due to breed-specific differences in the dealing of infected cells with other immune cells, which ultimately influence the immune response responded against infections. Achieving maximum resistance to these diseases is the ultimate goal, is technically

    2016-04-01

    Based on the CATDAT damage and loss database we analyse global trends of earthquake losses (in current values) and fatalities for the period between 1900 and 2015 from a statistical perspective. For this time period the data are complete for magnitudes above 6. First, we study the basic statistics of losses and find that losses below 10 bl. US satisfy approximately a power law with an exponent of 1.7 for the cumulative distribution. Higher loss values are modelled with the General Pareto Distribution (GPD). The 'transition' between power law and GPD is determined with the Mean Excess Function. We split the data set into a period of pre 1955 and post 1955 loss data as in those periods the exposure is significantly different due to population growth. The Annual Average Loss (AAL) for direct damage for events below 10 bl. US differs by a factor of 6, whereas the incorporation of the extreme loss events increases the AAL from 25 bl. US/yr to 30 bl. US/yr. Annual Average Deaths (AAD) show little (30%) difference for events below 6.000 fatalities and AAD values of 19.000 and 26.000 deaths per year if extreme values are incorporated. With data on the global Gross Domestic Product (GDP) that reflects the annual expenditures (consumption, investment, government spending) and on capital stock we relate losses to the economic capacity of societies and find that GDP (in real terms) grows much faster than losses so that the latter one play a decreasing role given the growing prosperity of mankind. This reasoning does not necessarily apply on a regional scale. Main conclusions of the analysis are that (a) a correct projection of historic loss values to nowadays US values is critical; (b) extreme value analysis is mandatory; (c) growing exposure is reflected in the AAL and AAD results for the periods pre and post 1955 events; (d) scaling loss values with global GDP data indicates that the relative size - from a global perspective - of losses decreases rapidly over time.

    Full Text Available This article aims to highlight the quality of life that depends on necessary, harmonious and simultaneous satisfying of all human needs, instead of „one at a time”, health and economic insecurity being at the very foundation of it. A society that is focused on quality of life will be a society centered on the individual, their needs and aspirations. It needs to offer alternatives and choices of the individual and not to impose models. Coercion of society over the individual is an objective and necessary phenomenon. Its deepening is not, however, as required. Social environment based on quality of life must be characterized by the maximum possible degree of permissiveness in which the individual is educated in its contribution to social awareness.

    Pauly's (1968) [Pauly, M., 1968. The economics of moral hazard, Comment, American Economic Review 58, 531-537.] analysis of the welfare loss from insurance assumes that medical care consumption is not determined by income, but recent studies suggest it is. This study argues that (1) Pauly's analysis overstates the welfare loss because it includes the effect of income on consumption, (2) the relevant income effect is derived from income transfer from the healthy to the ill that occur when the probability of illness is less than 1, and (3) the welfare loss can be considered the transaction cost of insurance.

    Climate-forced ice losses are increasing potential for iceberg-seabed collisions, termed ice scour. At Ryder Bay, West Antarctic Peninsula (WAP) sea ice, oceanography, phytoplankton and encrusting zoobenthos have been monitored since 1998. In 2003, grids of seabed markers, covering 225 m(2) , were established, surveyed and replaced annually to measure ice scour frequency. Disturbance history has been recorded for each m(2) of seabed monitored at 5-25 m for ~13 years. Encrusting fauna, collected from impacted and nonimpacted metres each year, show coincident benthos responses in growth, mortality and mass of benthic immobilized carbon. Encrusting benthic growth was mainly determined by microalgal bloom duration; each day, nanophytoplankton exceeded 200 μg L(-1) produced ~0.05 mm radial growth of bryozoans, and sea temperature >0 °C added 0.002 mm day(-1) . Mortality and persistence of growth, as benthic carbon immobilization, were mainly influenced by ice scour. Nearly 30% of monitored seabed was hit each year, and just 7% of shallows were not hit. Hits in deeper water were more deadly, but less frequent, so mortality decreased with depth. Five-year recovery time doubled benthic carbon stocks. Scour-driven mortality varied annually, with two-thirds of all monitored fauna killed in a single year (2009). Reduced fast ice after 2006 ramped iceberg scouring, killing half the encrusting benthos each year in following years. Ice scour coupled with low phytoplankton biomass drove a phase shift to high mortality and depressed zoobenthic immobilized carbon stocks, which has persevered for 10 years since. Stocks of immobilized benthic carbon averaged nearly 15 g m(-2) . WAP ice scouring may be recycling 80 000 tonnes of carbon yr(-1) . Without scouring, such carbon would remain immobilized and the 2.3% of shelf which are shallows could be as productive as all the remaining continental shelf.

    Laying the foundations of property rights economics stands out among Ronald Coase's many seminal contributions. This approach had an impact on a number of fields in economics in, particularly, the 1960s and 1970s. The modern body of property rights economics mainly originates in the work Oliver...... Hart and is quite different in style, scope, and implications from the original property rights economics of Coase, Demsetz, Alchian, Cheung, Umbeck, Barzel, etc. Based on our earlier work on the subject (Foss and Foss, 2001), we argue that the change from Mark I to Mark II property rights economics...... led to a substantial narrowing of the scope of property rights economics, somewhat akin to a Kuhnian loss of content. In particular, Mark II property rights economics make strong assumptions concerning the definition and enforcement of ownership rights made which lead to many real life institutions...

    Fast Fourier transforms (FFT) is a basic approach to remote sensing image processing. With the improvement of capacity of remote sensing image capture with the features of hyperspectrum, high spatial resolution and high temporal resolution, how to use FFT technology to efficiently process huge remote sensing image becomes the critical step and research hot spot of current image processing technology. FFT algorithm, one of the basic algorithms of image processing, can be used for stripe noise removal, image compression, image registration, etc. in processing remote sensing image. CUFFT function library is the FFT algorithm library based on CPU and FFTW. FFTW is a FFT algorithm developed based on CPU in PC platform, and is currently the fastest CPU based FFT algorithm function library. However there is a common problem that once the available memory or memory is less than the capacity of image, there will be out of memory or memory overflow when using the above two methods to realize image FFT arithmetic. To address this problem, a CPU and partitioning technology based Huge Remote Fast Fourier Transform (HRFFT) algorithm is proposed in this paper. By improving the FFT algorithm in CUFFT function library, the problem of out of memory and memory overflow is solved. Moreover, this method is proved rational by experiment combined with the CCD image of HJ-1A satellite. When applied to practical image processing, it improves effect of the image processing, speeds up the processing, which saves the time of computation and achieves sound result.
